Referring to fig. 1 and 2, a control system provided by an embodiment of the present invention may include a touch switch 100 and a controlled device 300. When the touch switch 100 is applied to the control system, the principle, method, effect and the like thereof can be understood by referring to the description of the embodiments corresponding to the touch switch 100 and the control method thereof.

In fig. 1, a touch switch 100 and a controlled device 300 are illustrated, in an actual control system, the number of the touch switch 100 and the controlled device 300 may be multiple, and meanwhile, wired control may be implemented between the touch switch 100 and the controlled device 300, and/or wireless signals may be transmitted, where the wireless signals may be, for example, bluetooth, radio frequency, wifi, and the like.

The touch switch 100 is used for implementing the control method referred to hereinafter, and the following description of the control method is understood to refer to the description of the software and/or hardware operation, functions, and specific implementation of the touch switch 100.

The touch switch 100 can be manipulated to control a controlled device 300. The control may be direct control, for example, the touch switch 100 directly controls the on-off of a power supply circuit of the controlled device 300, or may be direct communication between the controlled devices 300 of the touch switch 100, so that the controlled device 300 performs corresponding operation according to an instruction sent by the touch switch 100, so that the response is more timely and the controlled device is not out of control due to network disconnection; the wireless communication module is arranged in the touch switch 100, so that the on-off of a circuit can be controlled by the touch of a user, and the wireless signal can be sent and received based on the built-in wireless communication module, thereby realizing wireless control. For example, as shown in fig. 2, the signal is processed and forwarded by the gateway 400, the touch switch 100 reports the corresponding instruction to the gateway 400, and the gateway 400 processes the instruction and then controls the corresponding controlled device 300.

The gateway 400 may be any device or combination of devices capable of forming and/or managing a network, and the number of the devices may be one or more, but is not limited thereto. The gateway 400 can realize protocol conversion and intercommunication among the touch switch 100, the terminal device 200 and the controlled device 300. Further, the gateway device 400 may be connected to the cloud to access the internet, so as to implement data exchange with other devices (e.g., the terminal device 200) accessing the internet. The gateway 400 may be a device dedicated to the gateway or may be another device having a gateway function (for example, a speaker device having a gateway function, a display device having a gateway function, a computer having a gateway function, a host, or the like). The gateway 400 may be a gateway, a router, or a device integrated with a gateway and a router. In addition, the gateway 400 may be an intelligent speaker equipped with a Wifi communication module (for communicating with the terminal device 200) and a radio frequency or bluetooth communication module (for communicating with the touch switch 100 or the controlled device 300), or may be a gateway device dedicated to data interaction and processing. The gateway device 400 may be configured with a separate bluetooth communication module, which may also be integrated with the Wifi communication module.

In an alternative embodiment, the touch switch 100 can be controlled by a user to turn on or off a line, and can also receive an external wireless signal and control the line to turn on or off according to the wireless signal. In addition, the touch switch 100 may emit a wireless signal to the outside to control other controlled devices 300 connected to the network through the gateway device 400. Specifically, both the touch switch 100 and the controlled device 300 may join the network of the gateway device 400 after the network is configured through bluetooth. The gateway device 400 may also access the internet to communicate with the terminal device 200, and further may display the touch switch 100 and the controlled device 300 that have been configured with the network on an Application (APP) of the terminal device 200, so that a user may configure a control policy for the controlled device 300 on the APP. When the touch switch 100 is touched, the touch information can be transmitted to the gateway apparatus 400 by transmitting a wireless signal, and the gateway apparatus 400 receives the touch information and controls the controlled apparatus 300, thereby realizing wireless control of the touch switch 100.

In an example, the gateway 400 is a bluetooth gateway 400, and the corresponding network is a bluetooth network, where the touch switch 100 is a touch switch 100 that performs wireless communication based on a bluetooth communication protocol. The touch switch 100 may transmit a bluetooth control message to control the controlled device 300 as a bluetooth receiver. In addition, the controlled device 300 may communicate with the bluetooth gateway 400, receive a control instruction of the bluetooth gateway 400, and report its own status to the bluetooth gateway 400. All controlled devices 300 accessing the bluetooth network where the bluetooth gateway 400 is located are stored in a device list of the bluetooth gateway 400, and after the touch switch 100 and the bluetooth gateway 400 are configured, a user can select any one or more controlled devices 300 in the bluetooth gateway 400 list as the controlled devices 300 of the touch switch 100.

The terminal device 200 may be any device or combination of devices having data processing capability and external communication capability, for example, it may be a mobile phone, a computer, a tablet computer, a car machine, etc.

The controlled device 300 may be any controlled device capable of being controlled by the touch switch 100, or a device connected to the controlled device, and in particular, the controlled device 300 may be, for example, a light fixture, a doorbell, an automatic curtain, an automatic window opener, or the like. The control it receives may be, for example, but not limited to:

controlling the controlled apparatus 300 or a device connected thereto to enter a certain state; such as turning on or off a light, pressing a doorbell, automatic curtain opening or closing, automatic window opener opening or closing, turning on or off a designated function of the controlled device 300, etc.;

controlling the controlled apparatus 300 or a device connected thereto to switch between two states; such as the on-off state of a toggle (switch) lamp, the on-off state of a toggle (switch) automatic window shade, the on-off state of a toggle (switch) automatic window pusher, the on-off state of a designated function of the toggle (switch) controlled device 300, and the like;

controlling the controlled apparatus 300 or a device connected thereto to change an operation parameter; such as adjusting the brightness/color temperature of the lamp, adjusting the degree of opening of the window covering, adjusting the degree of opening of the automatic window pusher, etc.

The specific control and control can be arbitrarily changed according to the application field of the touch switch 100, and all the specific control and control can be performed without departing from the scope of the embodiment of the invention.

Meanwhile, the following detailed description about the switching command and the touch signal can be understood by referring to the above description.

In a possible application scenario, the touch switch 100 may be used directly to control a power supply circuit of a lamp, when the touch switch 100 is driven by a human body (for example, touched), when the touch switch 100 receives a direct control signal directly sent by the local wireless switch 500 based on a bluetooth protocol, or when the touch switch 100 receives a network control signal sent by the router/gateway 400, a switch instruction is generated, where the switch instruction is used to switch an on/off state of the power supply circuit of the lamp to switch the lamp on/off.

It should be noted that, the schematic diagrams of the scenes of the control system shown in fig. 1 and fig. 2 are only examples, and the control system and the application scene of the touch switch described in the embodiments of the present application are for more clearly describing the technical solutions of the embodiments of the present application, and do not constitute a limitation to the technical solutions provided in the embodiments of the present application, and as a person of ordinary skill in the art can know that, along with the evolution of the control system of the touch switch and the appearance of a new service scene, the technical solutions provided in the embodiments of the present application are applicable to similar technical problems.

Referring now to FIG. 3, a schematic block diagram of a touch switch 100 in accordance with one embodiment of the present invention is shown;

wherein the touch switch 100 is adapted to be connected to and used to control a circuit.

As shown in fig. 3, the touch switch 100 at least includes a bottom case 3, a control module 216, a power supply module 217, and an execution module 218; wherein the control module 216 is configured to generate a switching command, and the power supply module 217 is adapted to electrically connect the control module 216 to the circuit and is capable of taking power from the circuit via the bottom case 3 to supply power to the control module 216; the execution module 218 is electrically connected to the power supply circuit to control the circuit according to the switching instruction. The circuit may be, for example but not limited to, a power supply line carrying 220v/50hz alternating current.

The execution module 218 may understand an on-off circuit formed by an element or a combination of elements having on and off states, for example, an on-off circuit having a relay or a thyristor as an action element, which is connected to a live wire of the circuit, for controlling the circuit on-off of the electrical consumer that is powered through the live wire. The execution module 218 is turned on, the loop is turned on, the execution module 218 is turned off, and the loop is turned off. The switching command may be understood as any signal capable of controlling the execution module 218 to switch on and off states.

The bottom shell 3 is adapted to be fixed in a wall, which may be understood as a wall for the circuit traces, and the bottom shell 3 is adapted to be fixed in a wall, which may be understood as an 86 x 86 bottom box reserved for fixing to a wall in use, although the size of the bottom box is not limited thereto. The specific implementation and use of the bottom case 3 can be understood by referring to the description of the embodiment shown in fig. 38 to 60, and the same parts will not be repeated in this embodiment.

The power supply module 217 includes a power conversion unit for converting the ac mains power in the circuit into a dc voltage suitable for the control module 216 and the execution module 218. In a specific example, the power conversion unit includes a BUCK circuit for converting 220V/50Hz ac power to 5V dc power for powering the execution module 218 and the vibration unit 25.

As shown in fig. 4, the apparatus further includes a step-down voltage stabilizing unit 2171 for stabilizing the dc voltage to a predetermined range and outputting the dc voltage for use by a circuit (e.g., a control module, a frequency generating unit) with higher power supply stability at the back end.

In a specific example, the buck regulator 2171 employs an LDO buck chip, and the 5V dc power is further converted into 3.3V power by the LDO buck chip to supply power to the control module 216. Of course, in other embodiments, the step-down voltage stabilizing unit 2171 may also use DCDC, which is not limited in this embodiment.

The touch switch 100 further has a first sensing unit 219, wherein the control module 216 is configured to be able to trigger generation of the switch instruction based on the first sensing unit 219; the first sensing unit 219 is configured to cover a first control distance.

In some embodiments, to further subdivide the first control distance to accommodate more diverse touch demands, the control module 216 is configured to have at least a first mode and a second mode, and the control module 216 is switchably operable in either the first mode or the second mode; the first control distance of the first mode is different from the first control distance in the second mode. In other words, the first control distance has a first designated distance (D1) in the first mode, the first control distance has a second designated distance (D2) in the second mode, and the first designated distance (D1) and the second designated distance (D2) are different to cover different manipulation ranges in the first mode and the second mode, respectively. The control module 216 is capable of adjusting the range of manipulation by switching between the first mode and the second mode.

Furthermore, in the above-mentioned scheme, since the first control distance in the first mode is different from the first control distance in the second mode, the control range of the control module 216 in the first mode is different from the control range in the second mode, so that the user can switch the first mode and the second mode based on the actual control requirement, so as to achieve the purpose of adjusting the control range of the touch switch 100. And it can be understood that the larger the control range is, the higher the touch sensitivity of the touch switch is, and conversely, the lower the sensitivity is, the user can adjust the sensitivity of the touch switch according to the switching of the first mode and the second mode so as to adapt to different control experience requirements. Further, the switching of the first mode and the second mode may depend on the external terminal device 200, such as a smart phone, a smart speaker, etc. Of course, manipulation of the touch switch 100 itself may also be relied upon, such as a continuous trigger for a specified time or a continuous trigger for a specified number of times to cause the touch switch 100 to switch between the first mode and the second mode.

In a possible application scenario, the touch switch 100 is used for controlling a kitchen lamp, and the user increases the first control distance by switching modes (a first mode and a second mode) to achieve the effect of manipulating the touch switch 100 at intervals, so as to prevent the greasy dirt from affecting the look and feel of the touch switch 100 after being stained on the surface of the touch switch 100.

In another possible application scenario, the touch switch 100 is used to control a room light of the elderly, and the first control distance can be reduced by switching modes (the first mode and the second mode), so that the effect of touch control of the touch switch 100 is achieved, so as to adapt to the pressing control of a traditional switch used by the elderly.

In summary, in the present embodiment, the user can further adjust the first control distance and the sensitivity of the touch switch 100 by switching the first mode and the second mode of the control module 216 to accommodate more diversified touch requirements.

FIG. 5 is a schematic diagram of a touch switch 100 according to an embodiment of the invention;

as shown in fig. 5, in order to solve the problem that the control manner of the conventional touch switch 100 is limited and single, in an embodiment of the present invention, the touch switch 100 has a second sensing unit 2112 and a third sensing unit 2111 in addition to the first sensing unit 219. Specifically, the control module 216 is configured to be able to generate the switching instruction based on triggering of at least one of the first sensing unit 219, the second sensing unit 2112, and the third sensing unit 2111; the first sensing unit 219 is configured to cover a first control distance, the second sensing unit 2112 is configured to cover a second control distance, and the third sensing unit 2111 is configured to cover a third control distance; the first control distance, the second control distance, and the third control distance are sequentially incremented such that the touch switch 100 is adapted to be triggered by multiple control distances.

The first sensing unit 219, the second sensing unit 2112, and the third sensing unit 2111 may be the same sensing method, or may be different sensing methods, so long as the purpose of distinguishing control distances can be achieved. Only one of the first sensing unit 219, the second sensing unit 2112, and the third sensing unit 2111 may be provided; there may be a plurality of each. The first sensing unit 219, the second sensing unit 2112 and the third sensing unit 2111 may have a linkage relationship therebetween, or may operate independently.

It should be noted that the first control distance, the second control distance, or the third control distance should be understood as the farthest distance that can control the touch switch 100. Taking the first control distance as an example, the first sensing unit 219 is configured to cover the first control distance, it may be understood that the control module 216 is within the first control distance based on a range in which the first sensing unit 219 can be operated, in other words, the control module 216 is configured to receive a driving action of a user within the first control distance based on the first sensing unit 219.

Furthermore, in the above-mentioned scheme, the control module 216 can be triggered by a plurality of sensing units with different control distances to realize coverage of different control distances, so that the touch switch 100 is not limited to a single control manner, and can be suitable for more control scenarios.

As shown in fig. 6, a schematic diagram of a touch switch 100 according to an embodiment of the present invention is shown;

as shown in fig. 6, the first sensing unit 219, the second sensing unit 2112 and the third sensing unit 2111 adopt different sensing modes. Specifically, the first sensing unit 219 triggers the control module 216 based on a contact/proximity sensing principle, the second sensing unit 2112 triggers the control module 216 based on a local wireless or wired control manner, and the third sensing unit 2111 triggers the control module 216 based on a network linkage manner. Further, in this embodiment, the first control distance, the second control distance, and the third control distance are increased, thereby realizing the coverage of a plurality of control distances.

As shown in fig. 6, according to an embodiment of the present invention, the third sensing unit 2111 receives a network control signal within a third control distance range based on a network communication protocol, and the control module 216 processes the network control signal to generate the switch command; the network control signal is communicated to the third sensing unit 2111 via the router and/or gateway 400, and the control module 216 may switch between a first mode and a second mode based on the third sensing unit 2111.

Specifically, the control module 216 may access a MESH network, for example, a MESH network of any communication mode such as WIFI, BLE, ZIGBEE, based on the third sensing unit 2111. The network control signal may be derived from a local area network, such as a local bluetooth MESH network established by the bluetooth gateway 400, or may be derived from a wide area network, such as a remote network control signal sent to the gateway 400 and/or router via a cloud server over the Internet. The control module 216 can access the MESH network via the router and/or the gateway 400 based on the third sensing unit 2111 to access the cloud server, and the user can remotely link the control module 216 through a terminal device (e.g., a mobile phone, a computer, etc.).

As shown in fig. 6, according to an embodiment of the present invention, the second sensing unit 2112 receives a direct control signal within the second control distance range based on a local communication protocol, and the control module 216 processes the direct control signal to generate the switching instruction; the direct control signal is sent by a remote controller which previously establishes a corresponding relation with the touch switch 100 based on the local communication protocol.

Specifically, the second sensing unit 2112 includes an integrated circuit in which the local communication protocol is burned and a radio frequency antenna used in combination, and the control module 216 receives a control message within the second control distance range through the second sensing unit 2112 to generate the switch instruction.

In one example, the local communication protocol may be, for example, a short code communication protocol, and the editable portion of the control message is less than or equal to 30 bytes.

Further by way of example, the local communication protocol may be, for example, a bluetooth radio frequency communication protocol, and the local device may be, for example, a bluetooth communication based battery wireless switch capable of controlling the touch switch 100 over a second control range of distances of at least 50 meters. Of course, in other embodiments, the local communication protocol may be other communication modes such as 433M radio frequency communication and near field communication, and the embodiment is not limited in particular.

Wherein the direct control signal may be, for example, a control message sent by a local device paired with the control module 216, where the control message is programmed based on the local communication protocol, so that the local second control distance is greater than 1 meter (e.g., a control message based on bluetooth communication may cover a control distance of about 50 meters). In particular, the local device may be a wireless switch, such as a battery wireless switch, a self-generating wireless switch, a wall switch with a wireless function, etc., and the direct control signal may be, for example, but not limited to, a wireless switch derived from a battery wireless switch, a self-generating wireless switch, and/or a wall switch, etc. The correspondence may be, for example, the pairing relationships described in the corresponding embodiments of fig. 19 to 37, and further, the establishment of the correspondence may be understood with reference to the process of establishing the pairing relationships. The process of establishing the specific pairing relationship between the wireless switch and the touch switch 100 can be understood with reference to the description of the corresponding embodiments of fig. 19 to 37.

In some embodiments, the control module 216 includes an integrated circuit with data processing capabilities and peripheral circuits thereof; the second sensing unit 2112 and the third sensing unit 2111 are integrally formed with the integrated circuit to share a signal receiving and transmitting antenna (for example, a wireless communication module 211 described in the embodiment).

In a specific example, the gateway 400 is a bluetooth gateway 400, the second sensing unit 2112 receives a direct control signal sent by the local wireless switch 500 based on bluetooth radio frequency, the third sensing unit 2111 receives a network control signal based on a bluetooth mesh network where the bluetooth gateway 400 is located, and the second sensing unit 2112 and the third sensing unit 2111 are integrated in an integrated chip (e.g. a bluetooth module) where the control module 216 is located and transmit and receive data through the same bluetooth antenna.

As shown in fig. 7, a block diagram of a touch switch 100 according to an embodiment of the present invention is shown;

as shown in fig. 7, in order to reduce the surge impact when the execution module 218 acts, the touch switch 100 further includes a surge suppression module 220 electrically connected to the control module 216, for detecting a zero crossing point of the alternating current in the circuit, where the control module 216 operates the execution module 218 according to the zero crossing point signal transmitted by the surge suppression module 220, so that the execution module 218 acts near the zero point, reducing the surge impact, and enhancing the use safety.

In addition, in order to more precisely detect the zero crossing position and to switch the action of the execution module 218 to be closer to the zero crossing position of the ac, in an embodiment, when the action of the execution module 218 needs to be controlled, the control module 216 continuously monitors the zero crossing signal transmitted by the surge suppression module 220, and performs the situation division according to the specific form of the zero crossing signal, specifically: as shown in fig. 8, if the control module 216 monitors that the zero crossing signal is changed from high to low, the execution module 218 is operated after delaying for a first specified time; if the zero crossing signal is detected to change from low to high, then the execution module 218 is operated after a second specified time is delayed; wherein the difference between the second specified time and the first specified time is less than or equal to T, T.epsilon.1 ms,1.5 ms. Preferably the second specified time is 4.6ms, the first specified time is 3.6ms, the difference is 1ms.

Further, to prevent the control module 216 from failing to control the execution module 218 to operate when the surge suppressing module 220 is abnormal, in some embodiments, the control module 216 continuously monitors the surge suppressing module 220 before operating the execution module 218, and if the zero crossing signal is not received after a continuous delay time, operates the execution module 218 to operate. The delay time may be understood as a time-out period for acquiring the zero crossing signal, and after the time-out period is exceeded, the execution module 218 is still controlled to act even if the control module 216 does not receive the zero crossing signal, so as to ensure that the execution module 218 acts smoothly when the surge suppression module 220 works abnormally. In a specific example, the delay time is 20 ms-120 ms; preferably 100ms.

As shown in fig. 9, a circuit diagram of an implementation of the surge suppression module 220 is shown, the surge suppression module 220 includes an optocoupler, an input terminal of the optocoupler is connected to the circuit to access the ac power in the circuit, an output terminal of the optocoupler is connected to the control module 216, an output signal ZVD of the optocoupler is pulled low when the ac power crosses zero, the control module 216 receives a low level, and when the ac power does not cross zero, the ZVD is pulled high, and the control module 216 receives a high level. The control module 216 identifies zero crossing signals based on the high and low levels communicated by ZVD.

As shown in fig. 10, a schematic diagram of a touch switch 100 according to an embodiment of the present invention is shown;

as shown in fig. 10, the touch switch 100 further includes a vibration unit 25 and a touch panel 11, wherein the touch panel 11 is configured to receive a driving action, the control module 216 drives the vibration unit 25 through a driving unit 2211, and the vibration unit 25 is elastically disposed on the bottom case 3 and directly or indirectly abuts against the touch panel 11 to transmit vibration feedback to the touch panel 11.

The driving unit 2211 may be understood as a driving circuit adapted to a driving element or a driving element construction of the vibration unit 25, and the control module 216 drives the vibration unit 25 to vibrate through the driving unit 2211, and the vibration may, for example, last for a certain period of time at a specified frequency and in a specified direction, wherein the specified frequency, the vibration time and the specified direction may be set by the control module 216. The control module 216, when triggered, provides vibration feedback to the user via the touch panel 11 by controlling the vibration unit 25 to vibrate, which may be divided into long and short vibrations according to the duration, for giving different vibration feedback.

It will be appreciated that in the mounted state of the touch switch 100, the bottom case 3 is fixed to the wall, and if the vibration unit 25 is fixed to the wall following the bottom case 3, the vibration feeling transmitted to the touch panel 11 is greatly reduced. Therefore, in this embodiment, the vibration unit 25 is elastically disposed on the bottom case 3 to enhance the vibration transmission of the vibration unit 25, so that the vibration of the vibration unit 25 can be efficiently transmitted to the surface of the touch panel 11, thereby giving the user timely touch feedback.

In a specific example, the insulating member 23 may be disposed on the elastic supporting structure of the bottom case 3 through a middle case, so as to be elastically supported on the bottom case 3. The elastic supporting structure may be integrally disposed on the bottom shell 3, or may be disposed independently of the bottom shell 3 and the middle shell, and may be understood as a structure that can be driven by at least one of the middle shell and the bottom shell 3 to generate elastic deformation, where the middle shell may be understood as the insulating member 23, or may be understood as a structure that carries the insulating member 23 and can interact with the elastic supporting structure, and the insulating member 23 may perform elastic movement with respect to the bottom shell 3 when the bottom shell 3 is installed in a wall body. The insulator 23 protrudes out of the bottom case 3, and when the touch panel 11 is mounted on the bottom case 3, the insulator 23 can be abutted against the insulator, so that vibration of the vibration unit 25 can be efficiently transmitted to the surface of the touch panel 11 through the insulator 23, and further, a user is given touch feedback. In specific examples, the specific implementation between the middle shell and the elastic support structure and the bottom shell 3 and the insulator 23 can be understood with reference to the description of the related embodiments shown in fig. 38 to 60, and will not be repeated here.

Further, the vibration unit 25 includes at least one linear motor that is provided to vibrate in a direction in which a driving motion is applied to the touch panel 11 in a forward direction, and a start time is 60ms or less, preferably 40ms. The start-up time is understood as the time required for starting the vibration to complete vibration, so that the vibration feedback can be transmitted to the touch panel 11 within 200ms after the touch panel 11 is touched by a human hand, avoiding bad use experience of the hysteresis of the vibration feedback.

In a specific example, the linear motor employs a Z-axis linear motor in which a Z-axis is set as a direction in which a driving motion is applied to the touch panel 11 in a forward direction; the driving unit 2211 adopts a driving chip, and the driving chip communicates with the control module 216 to receive vibration configuration data (such as vibration duration, vibration frequency, etc.) representing the target vibration characteristic, which is issued by the control module 216, and in specific operation, the driving unit 2211 outputs a PWM signal representing the vibration characteristic to the linear motor, and the Z-axis linear motor receives the PWM signal and demodulates the PWM signal to generate vibration representing the target vibration characteristic.

In some embodiments, the driving unit 2211 may use an IIC bus to communicate with the control module 216, the frequency generating unit 2191 may also use an IIC bus to communicate with the control module 216, and the frequency generating unit 2191 and the driving unit 2211 may share the IIC bus and set respective different addresses so that the control module 216 can perform differentiated data transceiving through the IIC bus according to the corresponding addresses.

As shown in fig. 11, a block diagram of the first sensing unit 219 involved in the above embodiment is shown;

as shown in fig. 11, the first sensing unit 219 involved in the above embodiment includes:

at least one frequency generating unit 2191 having an oscillation frequency;

at least one touch sensing unit 2192 receives a driving motion of a human body within a first control distance range, and generates an oscillation frequency change of the frequency generating unit 2191 by using the driving motion of the human body, wherein the frequency generating unit 2191 triggers the control module 216 to generate the switch command according to the oscillation frequency change.

The touch sensing unit 2192 may be understood as an electronic switch that generates an oscillation frequency change of the frequency generating unit 2191 using the human body driving action or a component composition; the touch switch 100 receives a driving action applied by a human body through the touch panel 11, which may be, for example, a space driving (i.e., the human body is not in contact with the touch panel 11) and a contact driving (i.e., the human body is in contact with the touch panel 11); at least part of the touch sensing unit 2192 (e.g., a second sensing piece 12 to be described later) is provided on the touch panel 11 to change the oscillation frequency of the frequency generating unit 2191 when the driving action is applied to the touch panel 11 by the human body.

Further, the control module 216 is configured to periodically query the frequency generation unit 2191 to actively confirm whether there is a driving action; the query period is set to [50ms,150ms ]; preferably 100ms. In other words, the control module 216 in this embodiment has a passive response mode that the passive receiving frequency generating unit 2191 triggers signals, and also has an active response mode that the active inquiring frequency generating unit 2191, and the passive response mode and the active response mode are combined to improve the response speed and accuracy.

In some embodiments, the frequency generation unit 2191 is configured to output a trigger signal for triggering the control module 216 when the oscillation frequency change amount reaches a specified threshold.

It is understood that the distance of the driving action of the human body received by the touch panel 11 is different, and the change amount of the oscillation frequency of the frequency generation unit 2191 is different by the touch sensing unit 2192. Based on this, in the present embodiment, the control module 216 is configured to obtain a first control instruction for adjusting the specified threshold based on the third sensing unit 2111 to adjust the first control distance.

The first control instructions may be encoded based on the network communication protocol and transmitted via the gateway 400 and/or the router. The first control instruction carries data indicating a target specified threshold, and the control module 216 receives the first control instruction through the third sensing unit 2111 to obtain the target specified threshold, so as to update the specified threshold in the frequency generating unit 2191 to the target specified threshold, so as to realize adjustment of sensitivity and switching of modes (a first mode and a second mode).

In a specific example, the user can switch the first mode and the second mode through the relevant setting interface of the mobile phone app, and default specified thresholds are preset in the first mode and the second mode, the user only needs to select the first mode or the second mode, the mobile phone app will automatically generate the first control instruction carrying the corresponding default specified threshold data, and send the first control instruction to the touch switch 100 through the router and/or the gateway 400, so that the user can achieve the purpose of quickly switching the modes through simple operation.

Further, the specified threshold in the first mode has a first value, and the specified threshold in the second mode has a second value; the first value is greater than the second value such that the first control distance in the first mode is less than the first control distance in the second mode. In other words, in the first mode, the variable (specified threshold) of the oscillation frequency required for the frequency generation unit 2191 to output the trigger signal is set to the first value, so that the control module 216 in the first mode has the manipulation range of the first specified distance D1; in the second mode, the variable (designated threshold) of the oscillation frequency required by the frequency generation unit 2191 to output the trigger signal is set to a second value, so that the control module 216 has a manipulation range of the second designated distance D2 in the second mode, and the first value is greater than the second value, so that the first designated distance D1 is smaller than the second designated distance D2.

Specifically, in one embodiment, the first value is set to [16khz,36khz ] and the second value is set to [5khz,15khz ] such that: the control module 216 is capable of being touch activated (as may be understood by the touch actuation above) within a first control distance range (first specified distance) of less than or equal to 1mm in a first mode and capable of being blank activated (as may be understood by the blank actuation above) within a first control distance range (second specified distance) of greater than 1mm in a second mode. The preferred first value is 26kHz and the second value is 10kHz. The first control distance in the second mode is further limited to less than 3cm, for example, the touch switch 100 can be operated at a distance of 1cm to 2cm from the touch panel, and the touch switch 100 can be operated in a manner of contacting the touch panel 11 in the first mode. To avoid the second mode being too sensitive to cause interaction between the plurality of tactile switches 100 during triggering.

As shown in fig. 12, in some embodiments, in order to enlarge the touch area of the sensing panel and implement large-area touch sensing, the touch switch further includes a touch panel 11 for receiving a driving action; the touch sensing unit 2192 includes a first sensing piece 22 and a second sensing piece 12 that can conduct electricity, the second sensing piece 12 is disposed on the touch panel 11, the first sensing piece 22 is disposed below the second sensing piece 12 and is electrically connected to the frequency generating unit 2191, and the second sensing piece 12 and the first sensing piece 22 form a coupling relationship to generate a change in oscillation frequency of the frequency generating unit 2191 by a driving action applied to the touch panel 11 by a human body; wherein the area of the second inductive tab 12 is larger than the area of the first inductive tab 22.

Furthermore, in this embodiment, the controllable area of each touch key of the touch switch 100 is lifted by the manner of overlapping and coupling the double-layer sensing pieces (the first sensing piece 22 and the second sensing piece 12), so as to realize large-area touch of each touch key, thereby facilitating blind operation and solving the problem that the touch position is not well found when the user touches due to limited touch area of the conventional touch switch 100.

In some embodiments, the touch panel 11 is detachably disposed on the bottom case 3, and a layer of insulation member 23 is laid on the surface of the first sensing piece 22 to isolate the first sensing piece 22 from the second sensing piece 12.

The detachable assembly mode between the touch panel 11 and the bottom shell 3 is beneficial to the replacement and personalized customization of the touch panel 11 in the later stage, and when the touch panel 11 is detached from the bottom shell 3, the touch switch 100 after the touch panel 11 is detached is still in an electrical isolation state due to the existence of the insulating piece 23, so that the use safety is enhanced.

In some embodiments, the frequency generating unit 2191 and the control module 216 are disposed on a control circuit board 21, the control circuit board 21 is disposed in the bottom case 3 in a sinking manner, and the first sensing piece 22 is suspended on the control circuit board 21 in order to reduce the thickness of the touch panel 11. The insulator 23 protrudes from the bottom case 3. Furthermore, the first sensing piece 22 is not disposed on the control circuit board 21 but is disposed in a manner of suspending above the control circuit board 21, so that the occupied area of the control circuit board 21 can be reduced, the volume of the control circuit board 21 can be reduced, the control circuit board 21 can be sunk into the bottom shell 3 to reduce the thickness of the touch panel 11 exposed outside the wall, and the first sensing piece 22 is disposed in a manner of suspending on the control circuit board 21 to increase the sensing distance, i.e. to properly raise the first control distance, so that the first control distance can be further subdivided during the switching between the first mode and the second mode.

The specific manner of setting the control circuit board 21 and the specific manner of setting the first sensing piece 22 and the second sensing piece 12 can be understood by referring to the descriptions of the corresponding embodiments shown in fig. 38 to 60.

As shown in fig. 13, a block diagram of the frequency generation unit 2191 is shown.

In some embodiments, as shown in fig. 13, the frequency generating unit 2191 includes at least one oscillator 21911, and the first sensing piece 22 and the second sensing piece 12 form a capacitive coupling relationship to change a capacitance value of a frequency selection network of the oscillator 21911 by using a driving action applied by a human body to change an oscillation frequency of the oscillator 21911.

In a specific example, the frequency-selecting network of the oscillator 21911 is formed by a capacitor and a resistor, the oscillator 21911 may include an RC oscillator, and the power supply module 217 supplies power to the RC oscillator through a voltage stabilizing circuit, so as to prevent the unstable power supply voltage from affecting the oscillation frequency and improve the stability of the oscillation frequency of the oscillator 21911.

Specifically, as shown in fig. 13, the operating principle of the RC oscillator may be, for example: the first sensing piece 22, the second sensing piece 12 and the reference ground form a capacitor C, the capacitor C and a resistor R form a positive input end of the frequency-selective network connected to an amplifier with the same phase ratio, a negative end of the amplifier with the same phase ratio is connected to a reference voltage VREF, the voltage supplied by the voltage-reducing and voltage-stabilizing unit 2171 charges the capacitor C through the resistor R, the amplifier outputs a low level before the voltage of the capacitor is lower than the voltage VREF, and after the voltage of the capacitor is higher than the voltage of the VREF, the amplifier outputs a high level, and then a switch is triggered to be turned on to discharge the capacitor C, so that the capacitor is charged again after the voltage of the capacitor is reduced, and an oscillation signal is output repeatedly. When a driving action is applied to the human body, the capacitance is changed, and thus the oscillation frequency of the RC oscillator is changed, and the driving action accepted by the touch panel 11 can be recognized by measuring the change in the frequency.

Specifically, as shown in fig. 13, when the driving motion is not applied to the human body, R, C is constant, the oscillation frequency of the oscillation signal is fixed, and when the driving motion is applied to the human body, C is changed, and the oscillation frequency follows the change. The amount of change in the C value varies depending on the driving operation applied by the human body, and the variable that affects the oscillation frequency varies, for example, as the distance between the human hand and the touch panel 11 increases, the amount of change in the C value increases as the distance between the human hand and the touch panel decreases, and for example, as the number of fingers increases, the amount of change in the C value increases and the number of fingers decreases when the driving operation is applied by the fingers. In this embodiment, the specified threshold is adjusted by the first control instruction, so as to adjust the difficulty of triggering the touch switch 100. In other words, the larger the specified threshold setting, the smaller the first control distance, i.e., the lower the sensitivity of the touch switch 100, and the larger the specified threshold setting, i.e., the higher the sensitivity of the touch switch 100.

In a specific example, when the human does not apply the driving action, the oscillation frequency is 2000kHz, when the human finger is 1cm away from the touch panel, the oscillation frequency is 1990kHz, and when the human finger is in contact with the touch panel 11, the oscillation frequency is 1970kHz. If the specified threshold is set to 10kHz, the touch switch 100 will be triggered when the human finger is 1cm from the touch panel. If the specified threshold is set to 26kHz, only a change in the oscillation frequency of 10kHz is caused when the human finger is 1cm away from the touch panel, and thus the touch switch 100 cannot be triggered, and when the human hand touches the touch panel 11, a change in the oscillation frequency of 30kHz is caused, exceeding 26kHz, the touch switch 100 can be triggered.

As shown in fig. 14, in some embodiments, the second sensing piece 12 of each touch sensing unit 2192 forms a touch area on the surface of the touch panel 11 (as shown in fig. 27), the touch sensing unit 2192 has a plurality of multi-area large-area touch modes to form the touch switch 100, and the frequency generating unit 2191 has a plurality of oscillators 21911 corresponding to each other, so that when the control module 216 is triggered, the touch area to which the driving action is applied in the plurality of touch areas is confirmed according to the corresponding oscillators 21911.

It can be understood that when the change of the oscillation frequency of any one of the plurality of oscillators 21911 reaches the specified threshold, the frequency generation unit 2191 outputs a trigger signal, and if the plurality of touch sensing units 2192 are sequentially and continuously triggered or the same touch sensing unit 2192 is repeatedly triggered in a short time, the single trigger signal passing through the frequency generation unit 2191 cannot be distinguished in detail, which is further unfavorable for complex operation of the touch switch 100. In this embodiment, on the basis that the control module 216 is interrupted by the frequency generation unit 2191 and passively triggered, the state of the frequency generation unit 2191 is periodically actively queried by the control module 216, so that the above adverse situation can be effectively avoided, and complex operations such as combined touch operation, continuous multiple touch operation, and touch operation lasting for a certain time of the touch switch 100 can be supported.

Wherein in some embodiments several of said oscillators 21911 are integrally provided. Of course, in other embodiments, the touch sensing unit 2192 may be constructed by using separate elements, and the embodiment is not limited in particular.

As shown in fig. 10, in some embodiments, each control channel is further provided with a light emitting unit 212, which can be controlled by the control module 216 to emit light.

The external illumination of the light emitting unit 212 may indicate one or more information, such as an operation state of the control module 216, for example, a change of an operation mode of the control module 216, and further, for example, whether the control module 216 sends out a signal, or what kind of signal. No matter what kind of information the light emitting unit 212 is used to indicate, it does not depart from the scope of the embodiment of the present invention.

In a specific example, the light emitting unit 212 includes a plurality of LED lamp sets, which are respectively corresponding to the touch sensing units 2192 and are used for indicating the touch sensing units 2192; each LED lamp group comprises at least two LED lamp beads with two colors so as to respectively indicate different states of the execution module 218 corresponding to the touch sensing unit 2192; wherein the LED lamp beads of the first color are even numbers, the LED lamp beads of the second color are odd numbers, and the LED lamp beads of the first color and the LED lamp beads of the second color are alternately arranged.

In a further example, the first color LED beads are 2 white LED beads, the second color LED beads are 3 yellow LED beads, and when the LED lamp is used specifically, two of the 3 yellow LED beads are arranged at two ends, and the other one is arranged in the middle; the 2 white LED lamp beads are arranged in an interpenetration mode between two adjacent yellow LED lamp beads to form a symmetrical arrangement relation, so that light is evenly emitted. The white light from the 2 white LED beads is used to indicate the execution module 218 is off, and the yellow light from the 3 yellow LED beads is used to indicate the execution module 218 is on.

The power supply module 217 converts 220V/50hz alternating current into 5V direct current by using a BUCK circuit, the BUCK voltage stabilizing unit 2171 uses an LDO chip ME6231C33M5G to BUCK and stabilize the 5V direct current output to be near 3.3V to supply power to the Bluetooth module MHCB 05P-B. The execution module 218 adopts a relay which is connected with a live wire of a circuit where the lamp is positioned to control the on-off of the live wire so as to control the on-off of the lamp, the relay is powered by 5V direct current and is controlled by a Bluetooth module MHCB05P-B, and the Bluetooth module MHCB05P-B drives the relay to be on-off through a triode amplifying circuit. The first sensing unit 219 employs a capacitive touch sensing chip BS83B04C, and is connected to the four-way touch sensing unit 2192, and the touch sensing unit 2192 employs double-layer sensing chip coupling (first sensing chip and second sensing chip). The surge suppression module adopts an optocoupler LTV-354T-A. The driving unit 2211 employs an AW86223QNR motor driving chip for driving the Z-axis linear motor L0832F.

PA1, PA3, PA4 and PA5 are respectively connected with respective anti-surge resistors (R34, R36, R38, R39) and matching capacitors (C21 to C24). The power supply terminal VDD of the touch sensing chip BS83B04C counts into the output power DVCC of the LDO chip ME6231C33M5G through C19, C20 and R31. The touch sensing chip BS83B04C communicates with the bluetooth module mhc B05P-B through the IIC bus to be set with the specified threshold, and outputs an interrupt trigger signal to the bluetooth module mhc B05P-B through the IRQ after the oscillation frequency change amount exceeds the specified threshold, and reads status data in the register of the touch sensing chip BS83B04C through the IIC bus after the bluetooth module mhc B05P-B is triggered to determine the touch sensing unit 2192 to which the driving action is specifically applied.

As shown in fig. 18, a block diagram of a touch switch 100 according to an embodiment of the present invention is shown;

as shown in fig. 18, in some embodiments, the touch switch 100 further includes an audio feedback unit 2213, and the control module 216 is electrically connected to the audio feedback unit 2213 so as to prompt an external output audio signal when the touch panel 11 is manipulated. The acoustic feedback unit 2213 may be, for example, but not limited to, a buzzer or the like.

As shown in fig. 18, in some embodiments, the touch switch 100 further includes a human presence module 2214, the human presence module 2214 is electrically connected to the control module 216, and is used for detecting whether a human body approaches, a detection distance of the human presence module 2214 is far greater than that of the first sensing unit (for example, more than ten times of the first control distance, 30cm to 100 cm), and the control module 216 is used for controlling the lighting unit to be turned on after receiving a signal of the human body detected by the human presence module 2214, and controlling the lighting unit to be turned off when a signal of the human body detected by the human presence module 2214 is not received. So as to realize the automatic control of the light signal of the indicating unit through the detection of the human body.

In some embodiments, the detection result of the human presence module 2214 may be linked with other functions, for example, when the circuit is a single fire circuit, in order to reduce the power consumption of the touch switch, the control module may be set to sleep when no person is present, and the control module is awakened sometimes, so as to reduce the power consumption of the control module, and prevent the excessive power consumption of the control module from affecting the normal off state (such as strobing) of the lamp in the off state.

To further reduce power consumption, the frequency generating unit, the driving unit, and all may be set to sleep even when no person is present, and wake up only when the human presence module 2214 detects the presence of a person.

In particular, the human presence module 2214 may be, for example, a microwave-based human presence sensor. In a specific example, an MS58-1616213M4 microwave human body presence detection chip can be used. In other embodiments, an infrared PIR human body sensor or a human body presence sensor with infrared and microwave integration may be used, and the embodiment is not particularly limited.

Referring to fig. 19, fig. 19 is a flowchart illustrating a control method according to an embodiment of the invention, which can be applied to the touch switch 100 in the above embodiment. As shown in fig. 19, the control method includes:

s301, the touch switch is switched to a first mode and a second mode according to a first control instruction.

In a specific embodiment, the touch switch is provided with a touch panel (which can be understood as the touch panel 11 described in the corresponding embodiments of fig. 1 to 18 and fig. 38 to 60), and can be touched to realize on-off control, and can communicate to the outside based on wireless communication. The wireless communication can be in any mode such as radio frequency, bluetooth, wifi, mobile network and the like. In one example, the touch switch may be a wall switch powered by a strong current. The wireless communication module is arranged in the touch switch, so that the wireless signal can be sent and received, and the wireless control is realized.

In an alternative embodiment, the first control instruction may originate from a terminal device. Specifically, the touch switch joins in a network (for example, a network of gateway devices) after the network is configured, so as to communicate with the gateway devices, where the gateway devices may also communicate with the terminal devices, and further the touch switch that has been configured may be displayed and may be controlled on an application program of the terminal devices. The terminal equipment generates and sends out a first control instruction based on the displayed touch switch after being controlled, and the touch switch receives the first control instruction and switches between a first mode and a second mode.

In the first mode, the touch switch can be triggered in response to a touch operation at a first designated distance D1 from the touch panel.

In a specific embodiment, in the first mode, the touch switch can be triggered in response to a touch operation at a first designated distance D1 from the touch panel, so that on-off control can be realized based on the touch operation, and a wireless signal can be emitted outwards based on the touch operation.

In an alternative embodiment, a first specified distance D1 ε [0,0.1cm ], wherein a setting of D1 to 0 indicates that the touch panel is touched, i.e., the touch switch can be touch-triggered in response to a touch operation in the first mode; d1 being set to be greater than 0 means that the touch panel is not touched, i.e., the touch switch can be activated at intervals in response to a touchless touch operation in the first mode, and it is required that the touch switch is brought closer to the touch panel, i.e., not more than 0.1cm, when activated.

In S303, in the second mode, the touch switch may be triggered in response to a touch operation performed at a first designated distance D1 or a second designated distance D2 from the touch panel, where the first designated distance D1 is smaller than the second designated distance D2.

In a specific embodiment, in the second mode, the touch switch can be triggered not only in response to the touch operation at the first designated distance D1 from the touch panel, but also in response to the touch operation at the second designated distance D2 from the touch panel, so that on-off control can be realized based on the touch operation, and a wireless signal can be emitted outwards based on the touch operation. Wherein the second specified distance D2 is greater than the first specified distance D1, that is, in the second mode the touch switch may be further from the touch panel than in the first mode when triggered by the space.

In an alternative embodiment, the second designated distance d2∈ (0.1cm, 2cm ] indicates that the touch panel is not touched, that is, the touch switch in the second mode can be triggered by a gap in response to a touchless touch operation, and the touch switch can be further away from the touch panel when triggered than in the first mode at this time, that is, the distance exceeds 0.1cm, so that the touch switch can be triggered by a gap (of course, the touch switch in the second mode can also be triggered within 0.1 cm), but in the second mode, the distance between the touch switch and the touch panel cannot be too far, that is, the distance does not exceed 2cm, so as to avoid inconvenience caused by frequent false touch of the touch switch in the second mode, and referring to fig. 20, the touch switch is a wall switch with strong electricity in the embodiment of the invention, and is mounted on a wall, and it is required to indicate that the touch switch shown here is conveniently triggered by a specific touch switch in the first mode, that the touch switch in the second mode is not longer than the first mode, that the touch switch in the first mode can be triggered by the touch panel can be designated as well, and the touch switch in the second mode can be triggered by the touch panel is not longer than the first mode.

It can be seen that in the above embodiment, the touch switch is provided with a touch panel, and in the first mode, the touch switch can be touch-triggered, and also can be spaced-apart to trigger in response to a touch operation closer to the touch panel (than in the second mode); in the second mode, the touch switch can be touch-triggered, but also can be spaced-apart to trigger in response to a touch operation that is farther from the touch panel (than in the first mode); the touch switch can further realize on-off control based on touch operation, and can also transmit wireless signals outwards based on touch operation so as to realize wireless control. The touch switch can be switched between a first mode and a second mode according to a first control instruction, so that the touch switch can be switched between a working mode of being triggered by touch, being triggered by short distance and being triggered by long distance, thereby being applicable to different application scenes and meeting the diversified requirements for the application scenes of the touch switch.

Referring to fig. 21, fig. 21 is a second flowchart of a control method according to an embodiment of the invention, and the control method can be applied to the touch switch 100 described above. As shown in fig. 21, the control method includes:

S501, the touch switch is switched to a first mode and a second mode according to a first control instruction.

For a specific description of step S501, reference may be made to the above description of step S301, which is not repeated here.

S502, in a first mode, the touch switch can be triggered by touch.

In a specific embodiment, in the first mode, the touch switch can be touch-triggered in response to a touch operation, so that on-off control can be realized, and wireless signals can be emitted outwards.

In an alternative embodiment, the touch switch is further provided with a vibration unit (which can be understood with reference to the vibration unit 25 described in the examples corresponding to fig. 1 to 18 and fig. 38 to 60) for providing vibration feedback. In practical applications, when a user touches the touch panel of the touch switch, the vibration unit may vibrate to provide vibration feedback to the user. Since the touch switch can only be touch-triggered in the first mode, the user can further feel vibration when touching the touch panel, so that whether the touch switch is triggered or not can be clearly known.

In S503, in the second mode, the touch switch can be triggered in response to a touch operation not more than 2cm from the touch panel.

In a specific embodiment, in the second mode, the touch switch can be touch-triggered, and also can be blank-triggered in response to a contactless touch operation. And the distance between the touch switch and the touch panel can not be too far when the touch switch is triggered at intervals, namely the distance is not more than 2cm, so that inconvenience caused by frequent error touch control of the touch switch due to the too far distance is avoided. Referring to fig. 22, fig. 22 is a schematic diagram showing a touch switch triggered in different modes according to an embodiment of the invention. As shown in fig. 22, the touch switch is a wall switch powered by strong electricity, and is mounted on a wall, and it should be noted that the touch switch shown here is only for convenience of description, and the structure of the touch switch is not particularly limited. The touch switch is provided with a touch panel, and it can be seen that the touch switch can be touch-triggered in the first mode, and the touch switch can be triggered in response to a touch operation of not more than 2cm away from the touch panel in the second mode.

It can be seen that in the above embodiments, the touch switch is provided with a touch panel and a vibration unit. In the first mode, the touch switch can be touch-triggered, and when a user touches the touch panel, the vibration unit can vibrate to provide vibration feedback for the user, so that the user can clearly know whether the touch switch is triggered. In the second mode, the touch switch can be triggered in response to a touch operation of not more than 2cm away from the touch panel, so that when a user is inconvenient to directly touch, for example, water stains are stained on hands or articles are held, the touch switch can still be triggered by approaching the touch panel; in some scenes needing to avoid direct contact, indirect contact can be achieved by triggering the touch switch by approaching to the touch panel, so that the diversified requirements for the application scene of the touch switch are met.

Referring to fig. 23, fig. 23 is a flowchart illustrating a control method according to an embodiment of the invention, which can be applied to the touch switch 100 described above. As shown in fig. 23, the control method includes:

s701, the touch switch sets a first designated touch area in the at least one touch area to a third mode according to a second control instruction, and an execution module (which may be understood with reference to the execution module 218 in other embodiments) corresponding to the first designated touch area in the third mode is kept in an on state.

In an alternative embodiment, the touch panel of the touch switch is divided into at least one touch area; the touch switch is also provided with at least one execution module corresponding to the at least one touch area, and the touch area receives touch operation to enable the corresponding execution module to switch on and off states. Specifically, the touch panel is divided into one or more touch areas, the touch switch can be connected to the electric appliances, and the on-off state of the touch switch is switched by the control execution module, so that the on-off state of a power supply loop of each electric appliance is controlled. For example, the execution module may be a relay, and the on/off of the power supply loop is controlled by controlling the relay to switch on/off states. For example, the touch switch is connected with a lamp, and a touch area on the touch panel is used for controlling the lamp; when the touch area is triggered by touch or is triggered by interval, the corresponding execution module switches the on state and the off state, so that the lamp is controlled to be turned on or off.

In a specific embodiment, the touch switch not only can be touched to realize on-off control, but also can set a first designated touch area in at least one touch area to be in a third mode according to a second control instruction; in the third mode, the first designated touch area can be touched to emit a wireless signal outwards. In other words, the first designated touch area will not be a function of a touch switch in the third mode, but a function of a wireless switch, which corresponds to a wireless remote control powered by a strong electricity.

In an alternative embodiment, the second control instruction may originate from a terminal device. Specifically, the touch switch of the matched network can be displayed and controlled on the application program of the terminal equipment. The terminal device generates and sends out a second control instruction based on the displayed touch switch after being controlled, and the touch switch receives the second control instruction and sets the first designated touch area to be in a third mode. In another alternative embodiment, the second control command may also originate from an operation on the first designated touch area, e.g. the second control command is generated after a designated operation is applied to the first designated touch area. The above description of the source of the second control instruction is merely an example, and the second control instruction may be an instruction that originates from another device or is generated based on another operation.

In the third mode, the execution module corresponding to the first designated touch area is kept in an on state. For example, the first designated touch area corresponds to a lamp, and before being set in the third mode, the lamp can be controlled to be turned on or off by touching the area; after being set to the third mode, the corresponding execution module keeps on state, that is, the lamp keeps on power supply state, and the power supply of the lamp cannot be controlled to be cut off by touching the area.

S702, the touch switch responds to the touch operation of the first designated touch area to transmit a wireless signal outwards, and the on state of the execution module is maintained.

In a specific embodiment, the execution module corresponding to the first designated touch area in the third mode is kept in an on state, and a wireless signal is emitted outwards when responding to a touch operation so as to realize wireless control; and at this point the execution module remains on. It can be seen that, in the third mode, the first designated touch area is only enabled to emit a wireless signal, but the corresponding execution module is not enabled to be disconnected, and when the intelligent device is connected to the corresponding power supply circuit, the following steps can be avoided: because the corresponding execution module is disconnected by the error touch control, the intelligent device is powered off and off, and cannot be controlled by the gateway device, so that inconvenience is caused in practical application.

In an alternative embodiment, in response to a touch operation on a first designated touch area, the touch switch reports a first event to a network, where the network refers to a network added after the touch switch is configured; the first event is used for indicating a touch operation on the touch area, so that a control result corresponding to the first event is executed by the controlled device. Specifically, after the touch switch is configured with the network, the touch switch can be displayed on the terminal device, and the mapping relation between at least one event reported by the touch switch and at least one control result can be configured, so that when the event is reported, the corresponding control result is executed by the controlled device, thereby realizing the intelligent and automatic control of the touch switch. For example, the touch panel is divided into four touch areas including a touch area 1, a touch area 2, a touch area 3, and a touch area 4; wherein the touch area 1 is set to the third mode, when the user clicks the touch area 1, the touch switch reports a click event of the touch area 1, so that a control result corresponding to the click event of the touch area 1 is executed. For example, if the control result corresponding to the clicking event of the touch area 1 configured on the terminal device is that an intelligent device is controlled to be turned on or turned off, the touch switch reports the clicking event in response to clicking the touch area 1, so as to trigger the intelligent device to be controlled to be turned on or turned off.

In another alternative embodiment, touching the first designated touch area in the third mode does not cause the corresponding execution module to be turned on or off, but the corresponding execution module can be turned on or off by a communication instruction or by an operating state control in which the touch switch is powered off and then powered on. Specifically, the terminal device may display the switch buttons corresponding to all the touch areas, and may specifically display a shortcut operation interface or a detailed operation interface; the shortcut operation interface displays all the switch buttons corresponding to the touch areas, so that a user can conveniently click the switch buttons to switch the switch buttons to be in an on state and an off state, and the corresponding execution modules are switched on or off; the detailed operation interface can display the switch buttons corresponding to all the touch areas, and can also perform other operation or configuration on the touch switch so as to meet the personalized requirements of users and improve the user experience. When a user clicks a switch button corresponding to a first designated touch area on the shortcut operation interface or the detailed operation interface to turn on or off, the terminal equipment sends a communication instruction to the touch switch through the gateway equipment, so that the corresponding execution module is turned on or off. In addition, the working states of the touch switch which is powered on after being powered off include a closed state, a memory state and an open state, and the working states can be configured on an operation interface of the terminal equipment. In the closed state, all execution modules are disconnected when the execution modules are powered on after being powered off; in the memory state, the state of any execution module when being powered on after being powered off is consistent with the state of the corresponding execution module before being powered off; in the on state, all execution modules are turned on when powered up after being powered down. That is, the execution module in the third mode can still be turned on or off by a communication instruction or according to the working state of power-on after power-off, so that a user can control the on or off of the execution module in the third mode through the terminal device according to the requirement. For example, when a lamp is connected, after the corresponding touch area is set to the third mode, the lamp cannot be controlled to be turned off by touching the touch area; when the lamp is required to be turned off, the lamp can still be controlled to be turned off through the terminal equipment, so that various control requirements of the touch switch are met, and the use experience of a user is improved.

Further, in an optional implementation manner, after the execution module corresponding to the first designated touch area is controlled to be turned on or turned off, the touch switch reports a second event or a third event to the network; the second event is used for indicating that the execution module corresponding to the touch area is turned on, and the third event is used for indicating that the execution module corresponding to the touch area is turned off, so that the control result corresponding to the second event or the third event is executed by the controlled device. Specifically, after the touch switch is configured with the network, the touch switch can be displayed on the terminal device, and the mapping relation between at least one event reported by the touch switch and at least one control result can be configured, so that when the event is reported, the corresponding control result is executed by the controlled device, thereby realizing the intelligent and automatic control of the touch switch. For example, the touch area 1 in the touch panel is set to a third mode, and when the user clicks a switch button corresponding to the touch area 1 on the operation interface to turn on or off, the terminal device sends a communication instruction to the touch switch, so that an execution module corresponding to the touch area 1 is turned on or off; the touch switch reports an on or off event of the touch area 1 to the network, so that a control result corresponding to the on or off event of the touch area 1 is executed. For example, the control result corresponding to the opening event of the touch area 1 configured on the terminal device is to control an intelligent device to be opened, the control result corresponding to the closing event of the touch area 1 configured on the terminal device is to control the intelligent device to be closed, and when the execution module is turned on or off in response to the operation on the terminal device, the touch switch reports the opening or closing event to trigger the intelligent device to be controlled to be opened or closed.

Referring to fig. 24, fig. 24 is a flowchart illustrating a control method according to an embodiment of the invention, which can be applied to the touch switch 100 described above. As shown in fig. 24, the control method includes:

s801, the touch switch sets a first appointed touch area in at least one touch area to a third mode according to a second control instruction, and an execution module corresponding to the first appointed touch area in the third mode is kept in an on state.

S802, the touch switch responds to the touch operation of the first designated touch area to transmit a wireless signal outwards, and the on state of the execution module is maintained.

For specific descriptions of steps S801 and S802, reference may be made to the above descriptions of steps S701 and S702, and the descriptions are not repeated here.

S803, the touch switch enters a locking mode according to a third control instruction; the on state of the execution module corresponding to the first designated touch area in the lock mode is locked, so that the execution module is not disconnected by any communication instruction in the lock mode. The communication command may be understood as a control command from the outside, such as a communication command sent by a smart speaker, a mobile phone app, or a gateway, etc. to disconnect the execution module.

In an alternative embodiment, the third control instruction may originate from the terminal device. Specifically, the touch switch of the matched network can be displayed and controlled on the application program of the terminal equipment. The terminal device generates and sends a third control instruction outwards based on the displayed touch switch after being controlled, and the touch switch receives the third control instruction and enters a locking mode.

In a specific embodiment, touching the first designated touch area in the third mode does not cause the corresponding execution module to be turned on or off, but the corresponding execution module can be turned on or off by a communication instruction. In some application scenarios, an intelligent device is connected to a power supply loop corresponding to a first designated touch area, and if an execution module corresponding to the area is disconnected by a communication instruction, the intelligent device is powered off and off-line, so that inconvenience is caused to a user; at the moment, the problem can be solved by entering a locking mode, the on state of an execution module corresponding to the area in the locking mode is locked, and the execution module cannot be disconnected by any communication instruction in the locking mode, so that the problem that the intelligent equipment is always powered off and off in some application scenes is solved; and the user can control whether the touch switch enters the locking mode or not through the terminal equipment, so that the degree of freedom of the user is also improved. In an alternative embodiment, the communication instruction may be a communication instruction sent by the terminal device to the touch switch through the gateway device when the user clicks a corresponding switch button on the operation interface to turn on or off the switch button. In another alternative embodiment, the communication instruction may also be a communication instruction generated by the gateway device based on the voice instruction and sent to the outside; for example, when the user controls the voice, the intelligent sound box with the gateway function can send a communication instruction to the touch switch based on the voice instruction to control the touch switch.

Referring to fig. 25, fig. 25 is a flowchart of a control method according to an embodiment of the invention, and the control method can be applied to the touch switch 100 described above. As shown in fig. 25, the control method includes:

s901, the touch switch sets a first appointed touch area in at least one touch area to be in a third mode according to a second control instruction, and an execution module corresponding to the first appointed touch area in the third mode is kept in an on state.

S902, the touch switch transmits a wireless signal outwards in response to the touch operation on the first designated touch area, and keeps the on state of the execution module.

For the specific description of steps S901 and S902, reference may be made to the related descriptions of steps S701 and S702, which are not repeated herein.

S903, the touch switch enters a locking mode according to a third control instruction; the on state of the execution module corresponding to the first designated touch area in the lock mode is locked, so that the execution module is not disconnected by any communication instruction in the lock mode.

For a specific description of step S903, reference may be made to the above description of step S803, which is not repeated here.

S904, according to a fourth control instruction, when the touch switch is powered on after being powered off, one of the following working states is realized: all execution modules are disconnected; the state of any execution module is consistent with the state of the corresponding execution module before power failure; all execution modules are on.

In a specific embodiment, the fourth control instruction may originate from the terminal device. The touch switch of the matched network can be displayed and controlled on the application program of the terminal equipment. The terminal equipment generates and sends a fourth control instruction outwards based on the displayed touch switch after being controlled, and the touch switch receives the fourth control instruction and switches the working state when the terminal equipment is powered off and then powered on.

In an alternative embodiment, the operating states of the touch switch that are powered up after being powered down include a closed state, a memory state and an open state, and the operating states can be configured on an operation interface of the terminal device to be switched between closed, memory and open. In the closed state, all execution modules are disconnected when the execution modules are powered on after being powered off; in the memory state, the state of any execution module when being powered on after being powered off is consistent with the state of the corresponding execution module before being powered off; in the on state, all execution modules are turned on when powered up after being powered down.

In the S905, in the locking mode, the execution module corresponding to the first designated touch area is not disconnected according to the working state that the touch switch is powered off and then powered on.

In a specific embodiment, the execution module corresponding to the first designated touch area in the third mode can be disconnected according to the working state that the touch switch is powered off and then powered on. For example, in the off state, no matter whether the execution module corresponding to the first designated touch area is turned on or off before power-off, the execution module is turned off after power-on again; for another example, in the memory state, if the execution module corresponding to the first designated touch area is disconnected before power-off, the state of the execution module after re-powering is consistent with that before power-off, i.e. disconnected. In some application scenarios, an intelligent device is connected to a power supply loop corresponding to a first designated touch area, and if an execution module corresponding to the area can be disconnected according to a working state that a touch switch is powered off and then powered on, the intelligent device may be powered off and off, so that inconvenience is caused to a user; at the moment, the problem can be solved by entering a locking mode, the on state of an execution module corresponding to the area is locked in the locking mode, and the execution module is not disconnected according to the working state that the touch switch is powered off and then powered on in the locking mode, so that the problem that the intelligent equipment is always powered off and off in some application scenes is solved; and the user can control whether the touch switch enters the locking mode or not through the terminal equipment, so that the degree of freedom of the user is also improved.

Referring to fig. 26, fig. 26 is a flowchart illustrating a control method according to an embodiment of the invention, which can be applied to the touch switch 100 described above. As shown in fig. 26, the control method includes:

s1001, the touch switch sets a first appointed touch area in at least one touch area to be in a third mode according to a second control instruction, and an execution module corresponding to the first appointed touch area in the third mode is kept in an on state.

S1002, the touch switch transmits a wireless signal to the outside in response to the touch operation on the first designated touch area, and maintains the on state of the execution module.

For the specific description of steps S1001 and S1002, reference may be made to the related descriptions of steps S701 and S702, which are not repeated herein.

S1003, the touch switch controls any one of the light emitting units (which can be understood as the light emitting unit 212 described in the corresponding embodiment of fig. 1 to 18) to emit or not emit the second light signal when the corresponding execution module is controlled to be turned off, and still emit the first light signal when the execution module is controlled to be turned on according to a fifth control command.

In a specific embodiment, the touch switch is further provided with at least one light emitting unit, corresponding to the at least one touch area, the light emitting unit being capable of emitting a first light signal and a second light signal of different colors to indicate an on state and an off state of the execution module corresponding to the touch area, respectively. Referring to fig. 27, fig. 27 is a schematic view of a touch panel according to an embodiment of the invention. As shown in fig. 27, the touch panel is divided into four touch areas, namely, a touch area 1, a touch area 2, a touch area 3, and a touch area 4, corresponding to the light emitting unit 1, the light emitting unit 2, the light emitting unit 3, and the light emitting unit 4, respectively. When the execution module corresponding to any touch area is switched on, the corresponding light-emitting unit emits a first light signal; when the execution module corresponding to any touch area is disconnected, the corresponding light-emitting unit emits a second light signal; wherein the first and second light signals are different in color to indicate an on state and an off state of the execution module. For example, the first light signal may be orange light, and the second light signal may be white light, so that the execution module emits orange light when turned on, and emits white light when turned off, so that the user can distinguish on or off. It should be noted that the colors of the first light signal and the second light signal are not orange or white, which is merely an example, so long as the colors are different to facilitate distinction.

Further, in an alternative embodiment, the fifth control instruction may originate from the terminal device. Specifically, the touch switch of the matched network can be displayed and controlled on the application program of the terminal equipment. The terminal equipment generates and sends out a fifth control instruction based on the displayed touch switch after being controlled, the touch switch receives the fifth control instruction and controls any one of the light emitting units to emit or not emit a second light signal when the corresponding execution module is disconnected, and the terminal equipment still emits a first light signal when the execution module is connected. For example, an indicator button is provided on the operation interface of the terminal device, and when the indicator button is clicked, the indicator button can be switched on or off. When a user clicks the indicator light button to turn on, the terminal equipment sends a fifth control instruction to the touch switch so that any one of the light emitting units emits a second light signal when the corresponding execution module is turned off and emits a first light signal when the execution module is turned on; when the user clicks the button to close the button, the terminal device sends a fifth control instruction to the touch switch so that any one of the light emitting units does not emit a second light signal when the corresponding execution module is turned off, and still emits a first light signal when the execution module is turned on. For example, the first light signal is orange light and the second light signal is white light; when the indicator lamp button is turned on, the corresponding light-emitting unit emits white light if the execution module is turned off, and the corresponding light-emitting unit emits orange light if the execution module is turned on; when the indicator light button is turned off, if the execution module is turned off, the corresponding light-emitting unit does not emit white light, and if the execution module is turned on, the corresponding light-emitting unit still emits orange light.

Through the function of setting the on or off of the indicator lamp button, a user can flexibly set whether the corresponding light-emitting unit emits light when the execution module is disconnected. For some users, the indication lamp button can be set to be turned on, so that the corresponding light-emitting unit emits light when the execution module is turned off, and thus the user can conveniently find the corresponding switch to operate at night. But to the sensitive user of light source when night, then can set up the pilot lamp button and close and make the luminescence unit that corresponds when the execution module disconnection not give out light to the better sleep of user, can satisfy different crowds' user demand like this. In addition, no matter the indicator light button is turned on or turned off, the execution module still emits a first light signal when being turned on, so that a user can know that the area is turned on clearly, and the situation that the area is turned off due to incorrect touch is avoided.

Referring to fig. 28, fig. 28 is a flow chart of a control method according to an embodiment of the invention, and the control method can be applied to the touch switch 100 described above. As shown in fig. 28, the control method includes:

and S1201, the touch switch sets a first appointed touch area in at least one touch area to be in a third mode according to a second control instruction, and an execution module corresponding to the first appointed touch area in the third mode is kept in an on state.

S1202, the touch switch transmits a wireless signal outwards in response to the touch operation on the first designated touch area, and keeps the on state of the execution module.

For the specific description of steps S1201 and S1202, reference may be made to the related descriptions of steps S701 and S702, which are not repeated here.

And S1203, controlling any one of the light emitting units to emit or not emit a second light signal when the corresponding execution module is controlled to be turned off according to a fifth control instruction, and still emitting a first light signal when the corresponding execution module is controlled to be turned on.

The specific description of step S1203 may refer to the related description of step S1003, and will not be repeated here.

S1204, the touch switch receives a sixth control instruction, wherein the sixth control instruction comprises brightness information.

In an alternative embodiment, the sixth control instruction may originate from the terminal device. Specifically, the touch switch of the matched network can be displayed and controlled on the application program of the terminal equipment. The terminal device generates and sends a sixth control instruction outwards based on the displayed touch switch after being controlled, and the touch switch receives the sixth control instruction. For example, the operation interface of the terminal device has an indicator light brightness option that can be set, the user can set the indicator light brightness, and after the setting is completed, the terminal device generates a sixth control instruction carrying the brightness information and sends the sixth control instruction to the touch switch. For example, the indicator light brightness options displayed on the operator interface include a range of 0-100%, where 0 represents a brightness of 0, i.e., no lighting; where 100% represents the highest brightness. If the user does not configure the indicator light brightness on the terminal device, the indicator light brightness may be a default value, for example, the default indicator light brightness is 50%. The brightness of the indicator light refers to the brightness of the second light signal emitted when the execution module is turned off.

And S1205, controlling any one of the light emitting units by the touch switch to emit a second light signal based on the brightness indicated by the brightness information when the corresponding execution module is controlled to be disconnected.

In a specific embodiment, when the indicator light button displayed by the terminal device is set to be turned on, the corresponding light emitting unit emits a second light signal based on the brightness indicated by the brightness information when the execution module is turned off; when the indicator light button displayed by the terminal equipment is set to be closed, the corresponding light-emitting unit does not emit a second light signal when the execution module is disconnected; and the corresponding light emitting units emit the first light signal when the execution module is switched on, so that the brightness of the first light signal is fixed and is not controlled by the brightness information.

Through the function of setting the brightness of the indicator lamp, a user can flexibly set the brightness of the second light signal emitted by the corresponding light emitting unit when the execution module is disconnected. For the user sensitive to the light source at night, the corresponding light-emitting unit can be still set to emit light when the execution module is disconnected, the light-emitting brightness can be adjusted, the user can lower the brightness, the user can conveniently find the switch at night, the user can conveniently sleep, and the use requirement of the user can be further met. In addition, the brightness of the first light signal emitted by the light emitting unit is fixed and is not regulated and controlled by a user, so that when the brightness of the user-regulated indicator light is low or 0, the brightness of the first light signal cannot be low or even does not emit light, and the user cannot distinguish that the corresponding switch is in an on or off state at the moment.

Referring to fig. 29, fig. 29 is a flowchart illustrating a control method according to an embodiment of the invention, which can be applied to the touch switch 100 described above. As shown in fig. 29, the control method includes:

s1301, the touch switch sets a first appointed touch area in at least one touch area to be in a third mode according to a second control instruction, and an execution module corresponding to the first appointed touch area in the third mode is kept in an on state.

S1302, the touch switch transmits a wireless signal to the outside in response to the touch operation on the first designated touch area, and maintains the on state of the execution module.

For specific descriptions of steps S1301 and S1302, reference may be made to the above descriptions of steps S701 and S702, and the descriptions are not repeated here.

And S1303, controlling any one of the light emitting units to emit or not emit a second light signal when the corresponding execution module is controlled to be turned off and still emit a first light signal when the execution module is controlled to be turned on by the touch switch according to a fifth control instruction.

The specific description of step S1303 may refer to the related description of step S1003, which is not repeated here.

Further, in the case that the touch switch causes the light emitting unit to emit the second light signal when the corresponding execution module is turned off according to the fifth control instruction, steps S1304 and S1305 are performed; steps S1306 and S1307 are performed in a case where the touch switch causes the light emitting unit not to emit the second light signal when the corresponding execution module is turned off according to the fifth control instruction.

In the third mode, the touch switch controls the light emitting unit corresponding to the first designated touch area to emit the second light signal.

In a specific embodiment, when the touch switch makes the light emitting unit emit the second light signal when the corresponding execution module is turned off according to the fifth control instruction, the light emitting unit corresponding to the first designated touch area keeps emitting the second light signal in the third mode. For example, when the execution module corresponding to any touch area is turned on or off, the corresponding light emitting unit emits orange light or white light respectively; wherein after the touch area 1 is set to the third mode, the light emitting unit corresponding to the touch area 1 remains to emit white light and is not controlled by the execution module corresponding to the touch area 1 being turned on or off. It can be seen that after the touch area is set to the third mode, the corresponding light emitting manner is different from the touch area not set to the third mode, so that the user can distinguish the touch area set to the third mode.

S1305, in response to the touch operation on the first designated touch area, the touch switch controls the corresponding light emitting unit to extinguish the second light signal and keep emitting the second light signal again.

In a specific embodiment, the light emitting unit corresponding to the first designated touch area keeps emitting the second light signal in the third mode, and when the touch operation is accepted, the corresponding light emitting unit extinguishes the second light signal and keeps emitting the second light signal. For example, after the touch area 1 is set to the third mode, the light emitting unit corresponding to the touch area 1 keeps emitting white light; when a user touches the touch area 1, the light-emitting units corresponding to the touch area 1 turn off the white light and keep emitting the white light again, namely the white light is always bright in the third mode, and the white light is always bright after blinking once when touched. It can be seen that the touch area set to the third mode blinks when touched by the user so that the user clearly knows whether the touch area is triggered. It should be noted that, after entering the lock mode, the light emitting mode of the light emitting unit corresponding to the first designated touch area is consistent with that when not entering the lock mode, and reference may be made to the description related to steps S1304 and S1305, which are not repeated here.

In S1306, in the third mode, the touch switch controls the light emitting unit corresponding to the first designated touch area not to emit the second light signal.

In a specific embodiment, in a case that the touch switch makes the light emitting unit not emit the second light signal when the corresponding execution module is turned off according to the fifth control instruction, the light emitting unit corresponding to the first designated touch area in the third mode does not emit the second light signal. For example, after the touch area 1 is set to the third mode, the light emitting unit corresponding to the touch area 1 does not emit white light and is not controlled by the execution module corresponding to the touch area 1 being turned on or off. It can be seen that after the touch area is set to the third mode, the corresponding light emitting manner is different from the touch area not set to the third mode, so that the user can distinguish the touch area set to the third mode.

S1307, in response to the touch operation on the first designated touch area, the touch switch controls the corresponding light emitting unit to emit the second light signal and then to keep not emitting the second light signal.

In a specific embodiment, the light emitting unit corresponding to the first designated touch area in the third mode does not emit the second light signal, and when the touch operation is accepted, the corresponding light emitting unit emits the second light signal and then keeps not emitting the second light signal. For example, after the touch area 1 is set to the third mode, the light emitting units corresponding to the touch area 1 do not emit white light; when a user touches the touch area 1, the light emitting units corresponding to the touch area 1 emit white light and remain non-emitting white light, namely the white light is always turned off in the third mode, and the white light is always turned off after blinking once when the user touches the touch area. It can be seen that the touch area set to the third mode blinks when touched by the user so that the user clearly knows whether the touch area is triggered. It should be noted that, after entering the lock mode, the light emitting mode of the light emitting unit corresponding to the first designated touch area is consistent with that when not entering the lock mode, and reference may be made to the related description of steps S1306 and S1307, which are not repeated here.

Referring to fig. 30, fig. 30 is a flowchart illustrating a control method according to an embodiment of the invention, and the control method can be applied to the touch switch 100 described above. As shown in fig. 30, the control method includes:

s1401, in response to a touch operation on any touch area, the touch switch reports a first event to a network, where the first event is used to indicate the touch operation on the touch area, so that a control result corresponding to the first event is executed by the controlled device.

In a specific embodiment, a network is added after the touch switch is configured, the touch switch can be displayed on the terminal device, and the mapping relation between at least one event reported by the touch switch and at least one control result can be configured, so that when the event is reported, the corresponding control result is executed by the controlled device, and the intelligent and automatic control of the touch switch is realized.

Specifically, when the touch area is touched, a first event is reported to the network, wherein the first event is used for indicating a touch operation on the touch area, namely a click event. For example, if the control result corresponding to the clicking event configuring the touch area 1 on the terminal device is to control the intelligent air conditioner to be turned on or turned off, the touch switch reports the clicking event of the touch area 1 in response to clicking the touch area 1, so as to trigger the intelligent air conditioner to be turned on or turned off.

And S1402, the touch switch also reports a second event or a third event to the network, wherein the second event is used for indicating that the execution module corresponding to the touch area is controlled to be turned on, and the third event is used for indicating that the execution module corresponding to the touch area is controlled to be turned off, so that the control result corresponding to the second event or the third event is executed by the controlled equipment.

In a specific embodiment, in response to a touch operation on any touch area (excluding the touch area set to the third mode), the touch switch reports not only the first event but also the second event or the third event, so that a control result corresponding to the second event or the third event is also executed.

Specifically, when the touch area is touched so that the corresponding execution module is connected, a second event is reported, wherein the second event is used for indicating that the execution module corresponding to the touch area is connected, namely, an opening event; and when the touch area is touched to disconnect the corresponding execution module, reporting a third event, wherein the third event is used for indicating that the execution module corresponding to the touch area is disconnected, namely, the event is closed. For example, the touch area 1 is not set to the third mode, and the control results corresponding to the clicking event, the opening event and the closing event of the touch area 1 configured on the terminal device are that the intelligent air conditioner is controlled to be opened or closed, the intelligent television is controlled to be opened and the intelligent television is controlled to be closed. For example, when the user touches the touch area 1, the touch switch reports a click event and a start event of the touch area 1, thereby triggering the intelligent air conditioner to be turned on and triggering the intelligent television to be turned on. It can be seen that when the touch area is touched, the touch switch can report not only a single click event but also an on or off event, that is, a user touches one touch area to control at least two intelligent devices. In some control scenes, a user can configure one touch area to correspond to a plurality of intelligent devices, so that the plurality of devices can be controlled by only one touch, and the requirement of the user on diversification of the control scenes is met.

Referring to fig. 31, fig. 31 is a flowchart illustrating a control method according to an embodiment of the invention, which can be applied to the touch switch 100 described above. As shown in fig. 31, the control method includes:

s1501, responding to a first appointed operation of any touch area, the touch switch broadcasts a distribution network message outwards, so that a terminal device can scan the distribution network message and display the touch switch.

In an alternative embodiment, the first designation operation may be an operation of applying three touches to any one of the touch areas and the third touch is continued for a first designation time, wherein the first designation time is set to 3s to 10s. Preferably, the first designated time is 5s, that is, when the user touches any touch area three times and the duration of the third touch reaches 5s, the touch switch broadcasts the distribution network message outwards. In a specific embodiment, the configuration network packet includes identification information of the touch switch, which is used for uniquely distinguishing the touch switch. After the terminal equipment scans the distribution network message, the touch switch can be displayed on an interface, and a user can select to distribute the distribution network to the touch switch.

S1502, after the touch switch displayed by the terminal equipment is selected, the touch switch joins a network of gateway equipment, and a corresponding relation with the terminal equipment is established, so that the terminal equipment can display the touch switch and can control the touch switch.

In a specific embodiment, the terminal device displays the touch switch after scanning the network distribution message, and after the touch switch is selected, the terminal device distributes the network to the touch switch so as to join in a network of a gateway device, thereby establishing a corresponding relationship with the terminal device. Specifically, after the network is configured, the touch switch can communicate with the gateway equipment; the gateway device may also interact with the terminal device so that the touch switch may be displayed and manipulated on the terminal device.

The touch switch joins the network of the gateway device after the network is configured, wherein the gateway device can also communicate with other controlled devices. The touch switch and other controlled devices of the distributed network can be displayed on an application program (APP) of the terminal device, so that a user can formulate a control strategy of the touch switch on the controlled devices on the APP. When the touch switch is touched, touch information can be sent to the gateway equipment, and the gateway equipment receives the touch information and controls the controlled equipment, so that intelligent control of the touch switch is realized.

In an alternative embodiment, after the execution module corresponding to any touch area is turned on or turned off, an eighth control instruction is sent to the terminal device, so that the switch button corresponding to the touch area displayed by the terminal device switches between an on state and an off state, and the state of the switch button is consistent with the state of the execution module.

In this embodiment, the terminal device may display the switch buttons corresponding to all the touch areas, and may specifically display a shortcut operation interface or a detailed operation interface; the shortcut operation interface displays the switch buttons corresponding to all the touch areas, so that a user can conveniently click the switch buttons to switch the switch buttons to an on state and an off state, and the corresponding execution modules are switched on or off; the detailed operation interface can display the switch buttons corresponding to all the touch areas, and can also carry out other configurations on the touch switch so as to meet the personalized requirements of users and improve the user experience.

Taking the touch panel divided into 4 touch areas as an example, please refer to fig. 32, fig. 32 is a schematic diagram of a shortcut operation interface in an embodiment of the present application. As shown in fig. 32, on the shortcut operation interface, switch buttons corresponding to the 4 touch areas of the touch switch, respectively, are displayed, and each of the switch buttons may be clicked to be switched to the on and off states. After clicking a switch button on the shortcut operation interface to switch on or off, the user can switch on or off the corresponding execution module. In addition, after any touch area is touched by a user to enable the corresponding execution module to be switched on or off, the touch switch sends an eighth control instruction to the terminal equipment, so that the corresponding switch button on the shortcut operation interface is switched on or off, the state of the corresponding switch button is consistent with that of the execution module, and synchronous display on the terminal equipment is realized. It can be seen that the state of the switch button on the shortcut operation interface indicates the state of the corresponding execution module, so that the user can clearly know the state of the execution module according to the display of the terminal device, and the user can use the shortcut operation interface conveniently.

Also taking the touch panel divided into 4 touch areas as an example, please refer to fig. 33, fig. 33 is a schematic diagram of a detailed operation interface in an embodiment of the present application. In an alternative embodiment, when clicking on "more operations" on the shortcut interface shown in FIG. 32, a jump may be made to the detailed operation interface shown in FIG. 33; in another alternative embodiment, the touch switch displayed on the terminal device may also be selected to directly enter the detailed operation interface as shown in fig. 33. As shown in fig. 33, the detailed operation interface displays switch buttons corresponding to the 4 touch areas of the touch switch, and each switch button can be clicked to switch between an on state and an off state, so that the corresponding execution module is turned on or off; and the detailed operation interface also displays a full-open button and a full-close button, clicking the full-open button can lead all the execution modules to be connected, and clicking the full-close button can lead all the execution modules to be disconnected. In addition, the name of each touch area displayed on the interface may be set; when "more function" is clicked, the touch switch may be further configured. After any touch area is touched by a user to enable the corresponding execution module to be switched on or off, the touch switch sends an eighth control instruction to the terminal equipment, so that the corresponding switch button on the detailed operation interface is switched on or off, the state of the switch button is consistent with that of the execution module, and synchronous display on the terminal equipment is realized. It can be seen that the state of the switch button on the detailed operation interface also indicates the state of the corresponding execution module, so that the user can clearly know the state of the execution module according to the display of the terminal device, and the user can use the device conveniently.

Further, after entering the locking mode, if an intelligent device is connected to the power supply loop corresponding to the touch area, the state of the switch button corresponding to the touch area on the shortcut operation interface or the detailed operation interface in the locking mode is used for indicating the state of the intelligent device. For example, the touch area 1 is set to the third mode, and a smart device is connected to the corresponding power circuit, and the on state of the execution module corresponding to the touch area 1 is locked after the lock mode is entered. At this time, the state of the switch button corresponding to the touch area 1 on the terminal device is not used for indicating the state of the execution module, but is used for indicating the state of the intelligent device. Specifically, the intelligent device can be controlled to be opened or closed by the wireless signal, and an instruction is sent to the terminal device, so that the switch button corresponding to the touch area 1 on the terminal device is switched to be in an opened or closed state, the state of the switch button is consistent with that of the intelligent device, a user can clearly know the state of the intelligent device according to the display of the terminal device, and the intelligent device is convenient for the user to use.

In another optional embodiment, the touch switch receives a ninth control instruction sent by the terminal device, where the ninth control instruction includes time information generated by the terminal device after the third designated touch area in the at least one touch area is set; and the touch switch controls the execution module corresponding to the third designated touch area to be switched on and/or switched off at the time indicated by the time information.

In this embodiment, a timing option can also be displayed on the operation interface of the terminal device, and the user can select to set the timing on and/or off for the third designated touch area. For example, when the touch area 3 is set to be turned on and off in a specified period of time, the touch switch controls the execution module corresponding to the touch area 3 to be turned on at the start time of the specified period of time and turned off at the end time of the specified period of time. For another example, when the touch area 3 is set to be turned on or off at a designated time point, the touch switch controls the execution module corresponding to the touch area 3 to be turned on or off at the designated time point.

Referring to fig. 34, fig. 34 is a flowchart eleven of a control method according to an embodiment of the invention, and the control method can be applied to the touch switch 100 described above. As shown in fig. 34, the control method includes:

s1801, in response to a second designation operation of a second designated touch area of the at least one touch area, causing the second designated touch area to enter a pairing mode.

In an alternative embodiment, the second designating operation may be an operation of applying a touch to the second designated touch area for a second designated time, wherein the second designated time is set to 1s to 6s. Preferably, the second designated time is 3s, that is, when the duration of the user touching the second designated touch area reaches 3s, the touch area enters the pairing mode.

In another alternative embodiment, in the pairing mode, the touch switch controls the light emitting units corresponding to the second designated touch area to alternately emit the first light signal and the second light signal according to the first designated frequency. For example, after the touch area 2 is touched for 3s to enter the pairing mode, the corresponding light emitting units can alternately emit orange light and white light according to the first designated frequency, that is, the orange light and the white light alternately flash, so that the user can clearly know that the area has entered the pairing mode.

And S1802, in the pairing mode, the touch switch receives a pairing message sent by a wireless switch.

In an alternative embodiment, the pairing message is generated and sent out after the wireless switch is applied with the third specified operation. The third specified operation may be a pressing operation of a key or an area on the wireless switch. For example, when any touch area of the touch switch is in a pairing mode and a button of a wireless switch is pressed, the wireless switch generates a pairing message and sends the pairing message outwards.

S1803, the touch switch establishes a pairing relation between the second designated touch area and the wireless switch, so that the execution module corresponding to the second designated touch area can be controlled to be switched on or switched off by the wireless switch.

Specifically, after the touch switch receives the pairing message, a pairing relationship between the second designated touch area and the wireless switch is established. After pairing, when the wireless switch is pressed, a wireless signal is generated, and then the touch switch receives the wireless signal and enables the paired execution module to be switched on or switched off. For example, the touch switch is arranged on a wall, the touch switch can be touched only when the user approaches the wall, but after the user is paired with a wireless switch, the wireless switch is controlled so as to control the touch switch, so that the control mode of the touch switch is enriched, and the user can use the touch switch conveniently.

In an alternative embodiment, the second designated touch area may establish a pairing relationship with at most m wireless switches; after a pairing relation is established with the m wireless switches, responding to a second appointed operation on the second appointed touch area, controlling a light-emitting unit corresponding to the second appointed touch area to alternately emit a first light signal and a second light signal for appointed times according to a second appointed frequency, and controlling the second appointed touch area to exit a pairing mode; wherein the first designated frequency and the second designated frequency may be set to be the same or different.

In this embodiment, m may be 10, i.e., any touch area of the touch switch may be paired with at most 10 wireless switches. For example, after the touch area 2 has been paired with 10 wireless switches, if the touch area 2 is touched for 3 seconds again to enter a pairing mode, the corresponding light emitting units alternately emit orange light and white light twice according to the second designated frequency, that is, the orange light and the white light alternately flash twice; and after flashing, exiting the pairing mode. In this way, the user can distinguish between the touch switch that can be paired and the touch switch that is full of pairing and cannot be paired according to the number of blinks. In addition, the first designated frequency and the second designated frequency may be the same or different, and the user may distinguish according to the number of flashes when the same is used, and the user may distinguish according to the number of flashes and the number of flashes when the same is used.

In another alternative embodiment, after the second designated touch area enters the pairing mode, the area is controlled to exit the pairing mode in response to a touch operation on the area; or when the second designated touch area does not establish a pairing relation with the wireless switch within the third designated time, controlling the area to exit the pairing mode.

In this embodiment, the third specified time may be 30s. For example, after the touch area 2 enters the pairing mode, touching the touch area 2 may cause the area to exit the pairing mode. For another example, when the touch area 2 is not paired with the wireless switch within 30 seconds after entering the pairing mode, the area also exits the pairing mode.

Referring to fig. 35, fig. 35 is a flowchart illustrating a control method according to an embodiment of the invention, and the control method can be applied to the touch switch 100 described above. As shown in fig. 35, the control method includes:

s1901, the touch switch is switched between a first mode and a second mode according to a first control instruction.

In S1902, in the first mode, the touch switch can be triggered in response to a touch operation at a first specified distance D1 from the touch panel.

In S1903, in the second mode, the touch switch can be triggered in response to a touch operation of the first designated distance D1 or the second designated distance D2 from the touch panel, where the first designated distance D1 is smaller than the second designated distance D2.

For specific descriptions of steps S1901, S1902 and S1903, reference may be made to the related descriptions of steps S301, S302 and S303, which are not repeated herein.

S1904, the touch switch controls the vibration unit to vibrate or not vibrate in response to the touch operation according to a seventh control instruction, so as to turn on or off vibration feedback.

In an alternative embodiment, the seventh control instruction may originate from the terminal device. For example, an option of setting on or off of the touch feedback is displayed on the operation interface of the terminal device, and is set on or off based on the user, so that the vibration unit vibrates or does not vibrate in response to the touch operation, and vibration feedback can be provided when the vibration unit vibrates. If the user sets the touch feedback to be on, the user can feel vibration when touching the switch, so that whether the switch is triggered or not can be clearly known. If the user sets the touch feedback to be closed, the user can judge whether the switch is triggered according to the light of different colors emitted by the light-emitting unit when touching the switch, and noise caused by vibration can be avoided, so that the requirements of users with different sensitivity degrees to sound can be met.

In an embodiment, which is not shown, the present invention further provides a control method, which is applied to the touch switch in the above embodiment, where the touch switch is provided with at least one operation area, and corresponds to at least one execution module, and the operation area accepts a driving action to make the corresponding execution module switch between an on state and an off state, and the method includes:

entering a locking mode according to a first control instruction;

in a specific embodiment, the touch switch can receive a driving action to realize on-off control, and can communicate externally based on wireless communication. The wireless communication can be in any mode such as radio frequency, bluetooth, wifi, mobile network and the like. In one example, the touch switch may be a wall switch powered by a strong current, adapted to be connected to a circuit and turned on and off by other devices connected in the on-off control circuit of the switch. The touch switch is provided with at least one operation area corresponding to at least one execution module, and the operation area receives the driving action to enable the corresponding execution module to switch on and off states. For example, the execution module may be a relay, and the operation region receives the driving action such that the corresponding relay is turned on or off.

In an alternative embodiment, the first control instruction may originate from a terminal device. Specifically, the touch switch is added into a network after the network is allocated, so that the touch switch of the allocated network can be displayed and controlled on an application program of the terminal equipment. The terminal equipment generates and sends a first control instruction outwards based on the displayed touch switch after being controlled, and the touch switch receives the first control instruction and enters a locking mode. In another alternative embodiment, the first control command may also be derived from manipulation of the touch switch, for example, the first control command is generated to enter the lock mode after a specified operation is applied to the operation area of the touch switch; for example, the touch switch may be further provided with an area designated for entering the lock mode, and the first control command is generated after the designated area is manipulated to enter the lock mode. The foregoing description of the source of the first control instruction is merely an example, and the first control instruction may be an instruction that originates from another device or is generated based on another operation, which is not specifically limited herein.

The on state of the execution module corresponding to the operation area in the locking mode is locked, so that the execution module in the locking mode is not disconnected by any communication instruction; the operation area is set to a third mode, and the execution module is kept in an on state in the third mode and is not disconnected according to the driving action accepted by the operation area.

In a specific embodiment, the touch switch is provided with one or more operation areas, wherein the operation areas may be set to the third mode. In the third mode, the corresponding execution module of the operation area is kept in an on state, and the corresponding execution module is not disconnected after the driving action is applied to the operation area.

After the touch switch enters the locking mode, the on state of the execution module corresponding to the operation area set to the third mode is locked, and the execution module is not disconnected by any communication instruction in the locking mode. In an alternative embodiment, the communication instruction may be a communication instruction sent by the terminal device to the touch switch through the gateway device when the user manipulates the touch switch displayed on the terminal device so that the execution module is disconnected. In another alternative embodiment, the communication instruction may also be a communication instruction generated by the gateway device based on a voice instruction and sent to the outside; for example, when the user controls the voice, the intelligent sound box with the gateway function can send a communication instruction to the touch switch based on the voice instruction to control the touch switch.

It can be seen that, in the above embodiment, the execution module corresponding to the operation area in the third mode is kept in the on state and is not disconnected by the driving action; further, after the locking mode is entered, the on state of the execution module corresponding to the operation area is locked and cannot be disconnected by any communication instruction. That is, the execution module corresponding to the operation area set to the third mode in the lock mode is not disconnected by the driving action nor by the communication instruction. In some application scenarios, the touch switch is connected to a circuit and the circuit is connected to at least one intelligent device, and if the corresponding execution module is disconnected, the intelligent device is powered off and off, thereby causing inconvenience to the user. At the moment, the problem can be solved by entering a locking mode, the on state of the execution module in the locking mode is locked and cannot be disconnected by the driving action or the communication instruction, so that the problem that the intelligent equipment is always powered off and off in some application scenes is solved, and the limitation of the use scenes of the touch switch is improved. And the user can control whether the touch switch enters the locking mode or not through the terminal equipment, so that the degree of freedom of the user is also improved.

In some embodiments, prior to entering the locked mode according to a first control instruction, the method further comprises:

Setting the operation area to a third mode according to a second control instruction; and in a third mode, a wireless signal is transmitted outwards in response to the driving action of the operation area. In other words, the operation area in the third mode will not be the function of a touch switch any more, but the function of a wireless switch, which corresponds to a wireless remote control powered by strong electricity.

In some embodiments, the method further comprises:

according to a third control instruction, when the touch switch is powered off and then powered on, one of the following working states is realized: all the execution modules are disconnected; the state of any execution module is consistent with the state of the corresponding execution module before power failure; all the execution modules are connected;

and the execution module corresponding to the operation area in the locking mode is not disconnected according to the working state that the touch switch is powered off and then powered on.

In some embodiments, the touch switch is further provided with at least one light emitting unit, and corresponds to at least one operation area, and the touch switch is suitable for being connected into a circuit and controlling the working state of at least one controlled device connected in the circuit through the execution module; the method further comprises the steps of:

Before entering a locking mode, controlling the light-emitting unit to emit different light signals to indicate the working state of the execution module corresponding to the operation area; and

after entering a locking mode, controlling the light emitting unit to emit different light signals to indicate the working state of the controlled equipment; the touch switch changes different light signals of the light-emitting unit according to a first working state message reported by the controlled equipment.

In some embodiments, the touch switch is adapted to be connected to a circuit and to control the operating state of at least one controlled device connected in the circuit via the execution module; the method further comprises the steps of:

before entering a locking mode, reporting the working state of an execution module corresponding to the operation area, so that a terminal device indicates the working state of the execution module through an identifier; and

after entering a locking mode, the on state of an execution module corresponding to the operation area is locked, so that the terminal equipment indicates the working state of the controlled equipment through the identification; the terminal equipment changes the indication state of the mark according to a first working state message reported by the controlled equipment.

In some embodiments, the method further comprises:

after entering a locking mode, the on state of the execution module corresponding to the operation area is locked, so that the terminal equipment indicates the on state of the execution module through the first indication state of the identifier, the indication state of the identifier is changed after the terminal equipment receives the operation of turning off the execution module, and the first indication state of the identifier is recovered when the terminal equipment enters the interface again after exiting the interface where the identifier is located.

Further, the method further comprises:

after entering a locking mode, the on state of the execution module corresponding to the operation area is locked, so that the terminal equipment indicates the on state of the execution module through the first indication state of the identifier, and the terminal equipment can change the indication state of the identifier according to the second working state message reported by the touch switch, so that the identifier is restored to the first indication state;

The second working state message is reported after the touch switch receives a turn-off instruction sent by the terminal equipment; the turn-off instruction is sent after the terminal equipment receives the operation of turning off the execution module.

In some embodiments, the method further comprises:

after entering a locking mode, the on state of the execution module corresponding to the operation area is locked, so that the terminal equipment indicates the on state of the execution module through the first indication state of the identifier, the indication state of the identifier is changed after the terminal equipment receives the operation of turning off the execution module, and the first indication state of the identifier is recovered after a preset time.

Further, the method further comprises:

Referring to fig. 36-58, a touch switch 100 provided by the present invention is specifically described. The structural scheme of the touch switch 100 provided in the present embodiment may be used for the touch switch in the above embodiment or for implementing the control method in the above embodiment.

The conventional touch switch is generally in point touch control, and the touch control area is very small, and the reason is that: the conductive film of the touch switch is arranged inside the shell, and the area of the conductive film is small due to the limited space inside the shell, so that the area of a touch control area on the touch panel is small, and inconvenience is brought to the operation of a user. To this end, according to a first aspect of the present invention, there is provided a touch switch 100, as shown in fig. 36 and 37, comprising a touch panel 11 and a control circuit board 21, wherein the control circuit board 21 is electrically connected with at least one first sensing piece 22, and the first sensing piece 22 is laid between the touch panel 11 and the control circuit board 21; a second sensing piece 12 is laid between the touch panel 11 and the first sensing piece 22, the first sensing piece 22 and the second sensing piece 12 can conduct electricity, and the second sensing piece 12 is coupled with the first sensing piece 22 and is used for jointly sensing the touch input of the touch panel 11; the surface of the touch panel 11 for receiving a touch input is set as a first surface 111, and the projected area of the second sensing piece 12 on the first surface 111 is larger than the projected area of the first sensing piece 22 on the first surface 111. The first sensing piece 22 and the second sensing piece 12 may be conductive cloth, conductive paint, ITO film, metal film, carbon fiber plastic or other thin sheet structure with conductive property. The control circuit board 21 is provided with a sensing circuit, which can detect the capacitance change of the first sensing piece 22, when the finger of the user touches the touch panel 11, the first sensing piece 22 and the finger form a capacitance relation, so that the capacitance value of the first sensing piece 22 changes, and the control circuit board 21 judges the touch input of the user by detecting the capacitance value change of the first sensing piece 22. The first sensing piece 22 cannot be quite large due to the limitation of the shell structure, the second sensing piece 12 is arranged between the first sensing piece 22 and the touch panel 11, the coupling of the second sensing piece 12 and the first sensing piece 22 can be understood as the mutual coupling capacitance relation among the first sensing piece 22, the second sensing piece 12 and the fingers of a user, the capacitance of the first sensing piece 22 can be changed when the user touches the corresponding area of the second sensing piece 12, and the control circuit board 21 can obtain the touch input of the user by detecting the capacitance change of the first sensing piece 22. Because the projection area of the second sensing piece 12 is larger than that of the first sensing piece 22, the user can trigger the touch switch 100 by touching the corresponding area of the second sensing piece 12, so that the touch area is greatly increased, and the user does not need to deliberately find the position of the touch area, thereby improving the operation convenience. Moreover, since the second sensing piece 12 increases the touch area, the first sensing piece 22 does not need to be made large on the premise of ensuring the touch sensitivity, thereby reducing the occupation of the inner space of the housing, and enabling the touch switch 100 to be made thinner. In addition, since the second sensing piece 12 is closer to the touch panel 11 than the first sensing piece 22, the touch sensitivity is higher.

Further, as shown in fig. 37, 44 and 45, the first sensing piece 22 is not in contact with the second sensing piece 12, the second sensing piece 12 is laid on a surface of the touch panel 11 facing the first sensing piece 22, and an insulating member 23 is disposed between the first sensing piece 22 and the second sensing piece 12.

The insulating member 23 is used for isolating an internal circuit board, isolating a charged part inside the shell, so that the charged part is not contacted with the touch panel 11, and when the user removes the touch panel 11, the charged part is not exposed, so that the user can freely remove and replace the touch panel 11 to adapt to different use scenes, for example, the touch panel 11 with different patterns can be replaced to indicate different controlled devices; or the touch panel 11 with different key numbers is replaced, and then a plurality of touch areas are combined into the same touch area through software setting, so that the key number of the touch switch 100 can be quickly changed without changing hardware. Further, the insulating member 23 is made of a flame retardant material. In a specific embodiment, the touch switch 100 further includes a bottom case 3 and a panel assembly 1, where the bottom case 3 is fixedly mounted on a wall; the panel assembly 1 comprises the touch panel 11, a second induction piece 12 and a panel shell 13, wherein the panel shell 13 is fixedly connected with the touch panel 11, and the second induction piece 12 is paved between the touch panel 11 and the panel shell 13; the panel housing 13 is detachably connected to the bottom chassis 3 such that the touch panel 11 and the second sensing piece 12 are detachably connected to the bottom chassis 3.

In summary, the invention creatively separates two isolated sensing pieces into the shell and the panel assembly 1 in a capacitive coupling manner so as to jointly sense touch input, and the area of the second sensing piece 12 is increased to realize the function of large-area touch, thereby improving the convenience of touch operation, reducing the thickness of the panel assembly 1 and improving the safety of disassembling the panel assembly 1, and facilitating the replacement of the panel assembly 1 by a user to adapt to different use scenes.

Further, as shown in fig. 42, a preset distance d1 is provided between the first sensing piece 22 and the second sensing piece 12, where d1 is less than or equal to 20mm, so as to ensure that the touch sensitivity is not too low. In a preferred embodiment, d1=2 mm.

Further, as shown in fig. 40, 38 and 39, the pattern projected by the first sensing piece 22 on the first surface 111 is set as a first projected pattern 221, the pattern projected by the second sensing piece 12 on the first surface 111 is set as a second projected pattern 121, and the second projected pattern 121 covers at least 90% of the area of the first projected pattern 221. So that the first sensing piece 22 and the second sensing piece 12 form a positive capacitive coupling relationship, thereby improving the sensing sensitivity and ensuring that the corresponding position of the edge of the second sensing piece 12 can also be successfully touched to trigger the touch switch 100.

Further, as shown in fig. 39 and 40, the projection of the second sensing pieces 12 on the touch panel 11 is covered on the touch panel 11, a preset interval 123 is provided between the second sensing pieces 12, the second sensing pieces 12 are not contacted, and each second sensing piece 12 is provided with a second notch 122; when the touch input is applied to the opposite position of the second sensing piece 12, the opposite position of the preset interval 123 or the opposite position of the second notch 122, the control circuit board 21 can generate a trigger signal in response to the touch input. Wherein the second notch 122 extends through the second sensing piece 12, the second notch 122 may be a through hole located inside, a notch near the edge, or another type of notch. The second notch 122 is used for transmitting light, or avoiding shielding the microwave signal. In the actual use process, since the capacitive coupling of the second sensing piece 12 and the first sensing piece 22 is used to sense the touch input in the touch area, the area of the actually generated touch area is slightly larger than that of the second sensing piece 12, so that an overlapping area exists between the adjacent touch areas, and the preset interval 123 is used to separate the two second sensing pieces 12, so that the overlapping area between the adjacent touch areas is smaller, and false touch is prevented. According to the invention, by controlling the sizes of the preset interval 123 and the second notch 122, the touch control area can cover the preset interval 123 and the second notch 122, so that the opposite position of the touch input acting on the preset interval 123 or the second notch 122 can be sensed by the second sensing piece 12, and therefore, the touch switch 100 can be triggered at any position in the touch control area, and no touch control blind area can occur.

Further, as shown in fig. 39, the minimum value of the width of the second notch 122 of the second sensing piece 12 is b, and the preset interval 123 is L3, so that both b and L3 are smaller than 15mm, so that the second sensing piece 12 can sense the touch input when the touch input acts on the position opposite to the preset interval 123 or the position opposite to the second notch 122. The second notch 122 may be circular, rectangular, polygonal, or any other shape, and the minimum value b of the width of the second notch 122 may be the diameter of the circular notch, the length of the short side of the rectangular notch, the shortest width of the polygonal notch, the radius of the semicircular notch, etc. The applicant finds through many experiments that when the average thickness of the finger of the adult touches the touch panel 11, and when b or L3 is smaller than 15mm, it can be ensured that the finger touches the second notch 122 or the preset interval 123 to be opposite to the position, the touch switch 100 can be successfully triggered, and when b or L3 is larger than 15mm, the finger touches the second notch 122 or the preset interval 123 to be opposite to the position is insufficient to ensure that the touch switch 100 is 100% triggered. Therefore, the applicant sets the minimum value of the width of the second notch 122 and the preset interval 123 to be less than 15mm, so as to ensure the success rate of triggering. In a specific embodiment, as shown in fig. 39, the minimum value b=9.2 mm of the width of the second notch 122, and the preset interval l3=3 mm. In another embodiment, as shown in fig. 57, the control circuit board 21 is provided with a proximity sensing module 215, and the second sensing piece 12 is provided with a fourth notch 124 at a position opposite to the proximity sensing module 215, so as to avoid microwave signal emission of the proximity sensing module 215.

The touch area may be understood as a virtual key area of the touch switch 100, and the touch area may be single, two, three or four, which is equivalent to a single key, a double key, a triple key, or a four-key switch of a conventional switch. The effective touch area may be understood as a total area occupied by the touch area.

That is, when the number of the touch areas is changed, the area of the touch area is changed, so that the effective touch area is always distributed over the surface area of the touch panel 11, thereby maximally increasing the touch area and improving the control convenience. In a specific embodiment, as shown in fig. 36-39, the first sensing pieces 22 and the second sensing pieces 12 are four, and each second sensing piece 12 corresponds to a position of each first sensing piece 22; there is no contact between the first inductive pads 22 and there is no contact between the second inductive pads 12; the four second sensing pads 12 are combined to form one, two, three or four touch areas, and the touch switch 100 issues different control instructions in response to the different touch areas being touched. The combination may be understood as a logical combination, rather than a physical combination, that is, the trigger signals generated by triggering the plurality of second sensing pads 12 are set to the same trigger signal through software setting, so that the touch areas corresponding to the plurality of second sensing pads 12 are logically combined to the same touch area, and in this process, the number and the area of the first sensing pads 22 and the second sensing pads 12 are not changed. The scheme can quickly change the number of keys of the touch switch 100 without changing hardware, and is convenient and quick. And the number of keys is switched so as not to affect the effective touch area, and the effective touch area is always distributed on the surface of the touch panel 11. The first sensing pieces 22 are not contacted with each other, and the second sensing pieces 12 are not contacted with each other, so that the overlapping area between the adjacent touch areas is smaller, and false touch is prevented.

The third projection pattern may be understood as a projection pattern formed by the second sensing piece 12 and the through hole inside the second sensing piece 12. In a specific embodiment, the sum of the areas of the third projected patterns is equal to 80% of the area of the first surface 111, so as to ensure that any position touching the touch panel 11 can successfully trigger the touch switch 100.

The proximity sensing module 215 is configured as a microwave proximity sensing module 215, and is capable of sensing the proximity of a user's limb, and since the first sensing piece 22 and the second sensing piece 12 are conductive pieces, the first sensing piece 22 of the present invention has a shielding effect on the emission of microwave signals, and the second sensing piece 12 is provided with the third notch 224, and the fourth notch 124, so that the microwave signals can be emitted to the outside through the third notch 224 and the fourth notch 124; meanwhile, due to the shielding effect of the sensing piece, the microwave signal can only be emitted from the third notch 224 and the fourth notch 124, so that the directivity close to the sensing direction is better, and the microwave signal is not easy to be interfered. Further, the third notch 224 is formed between the two first sensing pieces 22, so that the sensing area loss caused by the third notch 224 is shared by the two first sensing pieces 22; the fourth notch 124 is opened between the two second sensing pieces 12, so that the sensing area loss caused by the fourth notch 124 is shared by the two second sensing pieces 12; thereby reducing the effect of the third gap 224 and the fourth gap 124 on the sensing area.

In yet another embodiment, as shown in fig. 58, each of the second sensing pads 12 forms a touch area on the first surface 111 of the touch panel 11, which is different from the embodiment of fig. 36 to 56 in that the number of touch areas is equal to the number of the second sensing pads 12, and the touch switch 100 sends different control instructions in response to touching different touch areas; the area of the touch area corresponds to the area of the second sensing pieces 12, the area of a single second sensing piece 12 decreases with the increase of the number of the touch areas, the shape formed by the outer contour of each second sensing piece 12 is projected on the first surface 111 to form a third projected pattern, and the sum of the areas of the third projected patterns is greater than 70% of the area of the first surface 111, so that the sum of the areas of the touch areas can be distributed on the touch panel 11. The number and the area of the touch areas of the touch switch 100 of the embodiment correspond to those of the second sensing pieces 12, that is, the number of the second sensing pieces 12 is one, and the single second sensing piece 12 occupies more than 70% of the area of the touch panel; the number of the second sensing pieces 12 of the double-bond touch switch 100 is two, and the two second sensing pieces 12 occupy more than 70% of the area of the touch panel; the three-key touch switch 100 has three second sensing pieces 12, and the three second sensing pieces 12 occupy 70% or more of the area of the touch panel; the four-key touch switch 100 has four second sensing pieces 12, and the four second sensing pieces 12 occupy 70% or more of the area of the touch panel. Wherein fig. 58 shows only a double-key touch switch 100 embodiment. Compared with the embodiment shown in fig. 36-56, in this embodiment, instead of forming single, double and triple bonds by combining four touch areas, the number of touch areas is corresponding to that of the second sensing pieces 12, so that the touch areas are more complete, no separation exists in the touch areas, and the touch sensitivity of each part in the touch areas is more consistent. Further, the number of the first notches 223 and the second notches 122 is equal to the number of the touch areas, so that the number of the first notches 223 and the second notches 122 is smaller, and the touch areas are more complete.

Further, in the embodiment shown in fig. 58, the number of the first sensing pads 22 is equal to the number of the second sensing pads 12, and the area of the first sensing pads 22 is reduced as the number of the touch areas is increased. Namely, the number of the first sensing pieces 22 of the single-key touch switch 100 is one; the number of the first sensing pieces 22 of the double-bond touch switch 100 is two; the number of the first sensing pieces 22 of the three-key touch switch 100 is three; the number of the first sensing pads 22 of the four-key touch switch 100 is four. The number and the area of the first sensing pieces 22 correspond to those of the second sensing pieces 12, so that the touch sensitivity of each touch area is more consistent.

The conventional touch switch is generally in point touch, the touch area is very small, and the touch blind area is very large, and the reason is that: the conductive film of the touch switch is arranged inside the shell, and the area of the conductive film is small due to the limited space inside the shell, so that the area of a touch control area on the touch panel is small, and inconvenience is brought to the operation of a user. To this end, according to a second aspect of the present invention, as shown in fig. 36 to 58, there is provided a touch switch 100 including: a touch panel 11; a plurality of second sensing pieces 12 disposed inside the touch panel 11 for sensing a touch input of the touch panel 11; a control circuit board 21 coupled to the second sensing piece 12, capable of generating a trigger signal in response to the touch input of the touch panel 11; the projection of the second sensing pieces 12 on the touch panel 11 is covered on the touch panel 11, a preset interval 123 is provided between the second sensing pieces 12, and each second sensing piece 12 is provided with a second notch 122; when the touch input is applied to the opposite position of the second sensing piece 12, the opposite position of the preset interval 123 or the opposite position of the second notch 122, the control circuit board 21 can generate a trigger signal in response to the touch input. The technical details of the touch panel 11, the control circuit board 21, and the second sensing piece 12 are described in detail above, and will not be described here again. The second sensing piece 12 is arranged at the inner side of the touch panel 11 instead of the inner side of the shell, so that the area of the second sensing piece 12 is not limited by the shell any more, the area is enlarged, the area of a touch area is greatly increased, and convenience is brought to operation. In addition, in the actual use process, since the second sensing piece 12 senses the touch input in the touch area, the area of the touch area generated by the second sensing piece 12 is slightly larger than that of the second sensing piece 12, so that an overlapping area exists between the adjacent touch areas, and the preset interval 123 has the effect of separating the two second sensing pieces 12, so that the overlapping area between the adjacent touch areas is smaller, and false touch is prevented. According to the invention, by controlling the sizes of the preset interval 123 and the second notch 122, the touch control area can cover the preset interval 123 and the second notch 122, so that the opposite position of the touch input acting on the preset interval 123 or the second notch 122 can be sensed by the second sensing piece 12, and therefore, the touch switch 100 can be triggered at any position in the touch control area, and no touch control blind area can occur.

Further, as shown in fig. 39, the minimum value of the width of the second notch 122 of the second sensing piece 12 is b, and the preset interval 123 is L3, so that both b and L3 are smaller than 15mm, so that the second sensing piece 12 can sense the touch input when the touch input acts on the position opposite to the preset interval 123 or the position opposite to the second notch 122. The technical details of the second notch 122 and the preset interval 123 are described in detail above, and are not described herein. The applicant finds through many experiments that when the average thickness of the finger of the adult touches the touch panel 11, and when b or L3 is smaller than 15mm, it can be ensured that the finger touches the second notch 122 or the preset interval 123 to be opposite to the position, the touch switch 100 can be successfully triggered, and when b or L3 is larger than 15mm, the finger touches the second notch 122 or the preset interval 123 to be opposite to the position, which is insufficient to ensure that the touch switch 100 is 100% triggered. Therefore, the applicant sets the minimum value of the width of the second notch 122 and the preset interval 123 to be less than 15mm, so as to ensure the success rate of triggering. In a specific embodiment, the minimum value b=9.2 mm of the width of the second notch 122, and the preset interval l3=3 mm.

Further, as shown in fig. 37 to 39, the touch panel 11 includes at least one touch area, and the control circuit board 21 generates a corresponding trigger signal in response to a touch input of each of the touch areas; the number of touch areas on the touch panel 11 may be changed, but the effective touch area formed by the touch areas together remains unchanged, so as to make full use of the surface area of the touch panel 11, where the effective touch area is set as an area on the touch panel 11 where the touch input can be sensed. The technical details of the touch area are described in detail above, and are not described herein.

Further, as shown in fig. 37 to 39, when the number of touch areas of the touch panel 11 is single, the effective touch area formed by the single touch area is the area of the entire touch panel 11; when the number of the touch areas of the touch panel 11 is two, the effective touch area formed by the two touch areas together is still the area of the whole touch panel 11; when the number of the touch areas of the touch panel 11 is three, the effective touch area formed by the three touch areas is still the area of the whole touch panel 11; when the number of the touch areas of the touch panel 11 is four, the effective touch area formed by the four touch areas is still the area of the entire touch panel 11.
