The applicant finds that the existing knob switch has defects, wherein a pressing part and a rotating part of the knob are in a split type design, when a user presses or rotates the knob, relative movement exists between the pressing part and the rotating part, friction exists, and the hand feeling is not smooth.

To this end, according to a first aspect of the present utility model, referring to fig. 1 to 25, there is provided a rotary press trigger device 100 (hereinafter referred to as "the present device") which can be used as a knob manipulation device for a knob wireless switch, a knob wall switch or other devices. As shown in fig. 2 to 4, the present apparatus includes: a rotation detection unit 6 for detecting a rotation input; a pressing detection unit 5 for detecting a pressing input; a pressing unit 1 that can be pressed to directly or indirectly trigger the pressing detection unit 5; a rotating part 2 connected to the rotation detecting part 6 through a connecting part 3, and driving the rotation detecting part 6 to rotate through the connecting part 3; and a reset portion 4 capable of providing a reset force, wherein the reset portion 4 is connected between the connection portion 3 and the pressing portion 1, so that when the rotation portion 2 rotates, the pressing portion 1, the reset portion 4 and the connection portion 3 simultaneously rotate, and the three portions of the pressing portion 1, the reset portion 4 and the connection portion 3 maintain a relatively stationary state while rotating. The rotational input may be understood as a rotational movement, a rotational force, etc., received by the rotating part 2. The pressing input may be understood as a pressing motion or a pressing force received by the pressing portion 1, or the like. The restoring portion 4 may be understood as a structure capable of providing a restoring force, such as a spring, a spring plate, a torsion spring, silica gel, rubber, foam, an elastic arm, etc., and this embodiment is described in detail only with reference to the spring, and other restoring structures may be considered as equivalent to the spring and still be within the scope of the present utility model. The pressing portion 1 is configured to receive a pressing force of a user, and the pressing portion 1 may directly trigger the pressing detection portion 5, or may indirectly trigger the pressing detection portion 5 through another member. When the user rotates the rotating part 2, the rotating part 2 drives the connecting part 3 to rotate, and then the connecting part 3 drives the rotation detecting part 6 to rotate, and the rotation operation of the user is detected through the rotation detecting part 6; when the user presses the pressing portion 1, the pressing portion 1 triggers the pressing detection portion 5, and the pressing operation of the user is detected by the pressing detection portion 5. According to the rotary pressing triggering device 100 provided by the utility model, the reset part 4 is arranged between the pressing part 1 and the connecting part 3, when a user rotates the rotary part 2, the connecting part 3, the reset part 4 and the pressing part 1 synchronously rotate and can be relatively static, so that the reset part 4 can provide reset force and simultaneously does not prevent the rotary motion of the rotary part 2, the rotary hand feeling of the user is smoother, and the rotary part 2 can rotate while the pressing part 1 is pressed, so that the operation of pressing and rotating is realized; in addition, since the pressing part 1 and the rotating part 2 are relatively static, friction is avoided between the pressing part and the rotating part, and the pressing and rotating hand feeling is better.

Further, in the conventional knob switch using the hollow encoder, the pressing portion and the rotating portion of the knob are generally designed in a split type, because the return spring is disposed between the pressing portion and the circuit board, and the return spring blocks the pressing portion from rotating, so that the pressing portion and the rotating portion need to be separated, a gap is reserved between the pressing portion and the rotating portion, so that the pressing and the rotating of the knob do not interfere, but the sealing performance of the knob is poor due to the gap. In this embodiment, since the pressing portion 1 and the rotating portion 2 are relatively stationary, the pressing portion 1 and the rotating portion 2 can be hermetically connected to each other, and the sealing performance of the device can be improved.

It should be noted that, if the pressing portion 1 is in sealing connection with the rotating portion 2, the pressing operation is easily triggered by a user during the rotating operation. Therefore, the reset portion 4 of the embodiment of the utility model not only can provide the reset force, but also can provide the pretightening force for the pressing portion 1, so that the pressing portion 1 cannot be loosened and collapsed, and further the false triggering of the pressing operation during the rotation operation is avoided.

The rotation detecting section 6 may be understood as an electronic component capable of detecting a rotational motion or a rotational force, such as a hollow encoder, a magnetic encoder, a photoelectric encoder, a torsion sensor, or other electronic components capable of detecting a rotational operation; in an embodiment, the rotation detecting section 6 is provided as a hollow encoder. Compared with a middle shaft encoder, the hollow encoder has the following advantages: 1. the model of the pressing detection part 5 can be freely selected, for example, a micro switch, a tact switch, a Hall switch and the like are selected, so that better pressing hand feeling is obtained; 2. the hollow encoder may be used with the display screen 8 (as in the embodiment shown in fig. 21-25) to achieve more functionality; 3. other electronic components may be disposed in the hollow portion of the hollow encoder, so that the performance of the electronic component is better, for example, the antenna 781 may be disposed in the hollow portion of the hollow encoder (such as the embodiment shown in fig. 7); 4. the pressing part 1 can be pressed in multiple directions, and pressing different parts can trigger different pressing detection parts 5 (as shown in the embodiment of fig. 16-17).

The rotating portion 2 and the connecting portion 3 of the present embodiment are positioned by the third hook 211, when the edge of the pressing portion 1 is pressed, the pressing motion of the pressing portion 1 is not a straight up-down motion, but is a tilting motion, so that the pressing hand feel of the pressing portion 1 is smoother, the pressing portion 1 can implement omni-directional pressing, and the omni-directional pressing can be understood that each position and the central position of the edge of the pressing portion 1 are pressed to trigger the pressing detection portion 5.

Further, as shown in fig. 9-14, the connecting portion 3 is provided with a limiting unit 35 facing the pressing portion 1, and the reset portion 4 is limited in the limiting unit 35, so that the relative position of the reset portion 4 and the connecting portion 3 is not changed, and the reset force provided by the reset portion 4 is more balanced; at the same time, the reset portion 4 and the connecting portion 3 are rotated synchronously, so that friction between the reset portion 4 and the pressing portion 1 is reduced.

Further, as shown in fig. 9 and 10, the return portion 4 includes four return springs 41 uniformly distributed along the circumferential direction of the connection portion 3; the return spring 41 is in contact with the pressing portion 1 and provides a return force to the pressing portion 1.

In this embodiment, the trigger post 111 is disposed at the center of the pressing portion 1, and the pressing portion 1 can be omnidirectionally pressed by matching with the 4 third hooks 211, so that when the user presses the edge of the pressing portion 1, the third hooks 211 are equivalent to fulcrums, and the pressing portion 1 is equivalent to a labor-saving lever, so that the pressing hand feel is better.

If 3 third hooks 211 are selected, when a position directly above a certain third hook 211 is pressed, the rotation axis of the pressing portion 1 moving up and down is the connecting line of the other two third hooks 211, so the rotation axis is close to the center of the pressing portion 1, at this time, the stroke of the center of the pressing portion 1 is relatively small, and the trigger post 111 extending from the center of the pressing portion 1 may not trigger the detection switch 51. If 5 or more third hooks 211 are selected, the requirement for the dimensional accuracy of each hook is higher except that the mold becomes complicated, which results in an increase in manufacturing cost and difficulty in disassembly, and in addition, when the number of the third hooks 211 is 6 or more, the hooks will interfere with the movement of the pressing portion 1.

Wherein the hollow portion of the hollow encoder may be understood as the inner region of the second sleeve 634 of the mount 62. The electrical connection includes soldering, wire connection, abutment, etc., and in particular embodiments, the proximity sensing module 78 and antenna 781 are soldered to the circuit board 71, respectively. The function of the antenna 781 is to improve the sensing distance and the sensing sensitivity close to the sensing module 78, the conventional antenna 781 is tiled on the circuit board 71, and the position of the antenna 781 is far away from the outside of the device and is easy to be blocked, so that the sensing distance is short and the sensing sensitivity is poor; in this embodiment, the antenna 781 is disposed in the hollow portion of the hollow encoder, and the antenna 781 is raised by a larger height relative to the circuit board 71, which corresponds to a distance between the antenna 781 and the user being pulled up, and the phase change increases the sensing distance close to the sensing module 78. Meanwhile, since the height of the antenna 781 is increased, the number of cases covering the antenna 781 is reduced, and the sensing sensitivity of the sensing module is improved.

In other embodiments, as shown in fig. 6, the latch 637 is made of a metal material, the latch 637 is soldered to the circuit board 71, and the latch 637 may also be used as an antenna near the sensing module 78. In a preferred embodiment, both the latch 637 and the antenna 781 are used as sensing antennas (sensing electrodes) in proximity to the sensing module 78, which not only improves the space utilization of the circuit board 71, but also improves the sensing effect in proximity to the sensing module 78 because the height of both the latch 637 and the antenna 781 is higher than that of the circuit board 71. The battery is used for power supply in this embodiment, and the proximity sensing module 78 is a capacitive proximity sensing chip, and improves the sensing strength by means of an external antenna, so that the power consumption of the chip is reduced, and the battery is more durable. The capacitive proximity sensing chip is provided with a leading-out polar plate, and the proximity detection function is realized by measuring the variation of the capacitance value formed between the human body and the leading-out polar plate; the specific capacitance value calculation formula is:

s is the relative area of the capacitor plates, d is the distance between the plates, ε _r Is the relative dielectric constant (which is an intrinsic parameter, related to the dielectric material). The latch 637 and antenna 781 are used together as the antenna, i.e., the extraction plate, of the proximity sensing module 78.

The C36 is used for adjusting the sensitivity, when the sensitivity is required to be maximum, the C36 is not arranged, and when the sensitivity is required to be reduced, the C36 corresponding to the capacitance value can be increased adaptively. R37 (47 Ω is a common choice) is used to prevent static electricity and to prevent the chip U2 from being damaged when there is a dead spot in E0. And C34 and C35 are reference capacitors of U2 and are used for adjusting the working modes of the chip, wherein the working modes are divided into a low-power consumption mode and a normal mode, and the working modes are respectively the low-power consumption mode when C34 and C35 are respectively 1uF and 100pF, and the normal mode when C34 and C35 are respectively 4.7uF and 100 nF. VDDHI is used for power supply, C31 and C32 are used for filtering, and R38 is used for current limiting. IO1 and IO2 can be used as GPIO ports or I2C ports, and when the program is burnt, the I2C ports are used for the program, and at the moment, R33 and R34 are used as pull-up resistors of I2C. When the program is not burnt, the communication processing module is used as a GPIO port, OUT is pulled down when the capacitance change is detected, the communication processing module is electrically connected with the OUT terminal, and when the low-level signal sent by the OUT terminal is identified, the communication processing module judges that the communication processing module is someone, and performs response control.

In some embodiments, as shown in fig. 12 and 13, the difference from the embodiment of fig. 9 is that the return portion 4 further includes a spring connector 42, and the spring connector 42 connects at least two return springs 41 together, so that the return springs 41 are not easy to pop up from the limiting unit 35 during assembly, thereby improving assembly efficiency.

According to a second aspect of the present utility model, there is provided a knob control system comprising: the above-described rotary press trigger device 100; a controlled device operatively connected to the rotary press trigger 100 such that the rotary press trigger 100 is capable of controlling the controlled device based on the rotary input and/or the press input. The controlled device may be understood as an execution terminal, such as a curtain motor, a lamp, an air conditioner, an electric fan, a window pusher, etc. The operable connection may be understood as a connection capable of transmitting signals, including wired connections such as wire connections, power carrier communication connections, etc., and wireless connections such as wifi connections, bluetooth connections, zigbee connections, etc.

According to a third aspect of the present utility model, there is provided a curtain motor control method applied to a knob control apparatus having a knob configured to be capable of tracking an external rotational input motion and to be pressed inward by a direction of a rotational axis of the rotational input motion. The knob control device can be a knob wall switch, a knob wireless switch, a knob emitter or other electrical equipment with a knob. The controlled target device may be a curtain, a window, a door, etc., and the utility model is described in detail with the curtain as an exemplary embodiment, and other embodiments adopting the scheme are all within the scope of the utility model.

The applicant finds that the existing method for controlling the curtain motor by using the knob control device has the defects, and specifically, the existing control method is as follows: the knob control device responds to the rotation input to control the rotation of the curtain motor so as to drive the opening and closing of the curtain, and when the rotation input is stopped, the knob control device also controls the curtain motor to stop rotating. Because the opening and closing speed of the curtain is slower, when the opening and closing stroke of the curtain is longer, a user needs to continuously rotate the knob for a long time to drive the curtain to finish the stroke, and the operation is too complicated.

In order to solve the above problems, as shown in fig. 26, the present utility model provides a curtain motor control method, comprising:

the motor starts to rotate in response to the first control command is understood to mean that the motor can continuously rotate without continuously receiving the first control command, but can continuously rotate only after receiving the first control command once. The coupling may be understood as a controlled connection, including an electrical connection, a wireless communication connection, or other connection, and in a particular embodiment is provided as a power carrier communication connection.

Wherein said adjusting the rotational state comprises adjusting at least one parameter of said motor: speed, direction, start-stop status. Compared with the existing control method, the control method provided by the utility model can enable the control of the curtain motor to be simpler and faster, and is specifically described as follows.

In an exemplary embodiment, the adjusting the rotation state specifically includes adjusting a start-stop state of the motor: the motor stops rotating in a rotating state in response to the second control instruction; and in a rotation stop state, starting rotation in response to the second control instruction. In the actual use process, a user applies one-time rotation operation to the knob, the knob control equipment sends out a first control instruction, the motor receives the first control instruction and starts to rotate continuously, and the motor drives the curtain to open or close; when the user applies the knob pressing operation, the knob control equipment sends out a second control instruction, and the motor receives the second control instruction to stop rotating, so that the curtain also stops moving. In the whole control process, a user does not need to control the motor to continuously rotate by continuously rotating the knob, so that the operation is simplified. In addition, the user can control the motor to rotate only by pressing the knob, specifically, when the motor is rotated, the user applies a pressing operation to the knob once, the motor stops rotating, the pressing operation is applied again, the motor continues to rotate toward the initial rotation direction, or rotates in the opposite direction to the initial rotation direction, and when the pressing operation is applied for the third time, the motor stops rotating. The motor can be controlled to rotate only by pressing operation, so that the motor can be controlled rapidly. The control method provided by the utility model is mutually matched with the pressing operation through the rotation operation, so that the curtain motor can be controlled conveniently and simply.

In another exemplary embodiment, the adjusting the rotation state specifically includes adjusting a rotation speed of the motor, and during actual use, the rotation speed of the motor may be set to a plurality of gears, such as three gears of low speed, medium speed, and high speed. When a user applies the second control command to the knob pressing operation, the knob control equipment sends the second control command, and the motor receives the second control command to sequentially switch each gear, so that the quick switching of the rotation speed gear of the motor is realized, and the movement speed of the curtain is further quickly switched.

In another exemplary embodiment, the adjusting the rotation state specifically includes adjusting a rotation direction of the motor, and in actual use, the rotation direction of the motor is controlled only by a pressing operation of the knob and is not controlled by the rotation direction of the knob. The user applies to knob one-time rotation operation, and knob control equipment sends first control command, and the motor receives first control command begins to rotate continually, and the motor drives the (window) curtain to open or close. In this process, the rotation direction of the motor is the same direction, which is set as the initial rotation direction, regardless of whether the direction of the rotation operation is the forward direction or the reverse direction. When the user applies the knob pressing operation, the knob control device sends out a second control instruction, the motor receives the second control instruction to stop rotating, and the rotating direction is switched. When the user applies the rotation operation again, the motor will rotate in a direction opposite to the initial rotation direction regardless of whether the direction of the rotation operation is forward or reverse. When the window curtain is used, a user only needs to apply the rotation operation in any direction to the knob, and if the movement direction of the window curtain is opposite to the expected direction, the user only needs to apply the knob pressing operation and apply the rotation operation again. The arrangement ensures that a user does not need to think about the direction before operating, and can realize the rapid opening and closing operation of the curtain.

In an exemplary embodiment, the adjusting the rotation state specifically includes adjusting a start-stop state of the motor, and the rotation operation includes a first rotation operation and a second rotation operation; issuing a first control command in response to a rotation operation such that the motor receives the first control command and starts rotating in response to the first control command; the method specifically comprises the following steps: issuing a first control command in response to the first rotation operation, so that the motor starts to rotate in a first direction in response to the first control command; or, a first control command is sent out in response to the second rotation operation, so that the motor starts to rotate in a second direction in response to the first control command; wherein the first rotational operation and the second rotational operation are in opposite directions, and correspondingly, the first direction and the second direction are opposite. The embodiment establishes a corresponding relation between the rotation operation direction and the motor rotation direction, so that a user can precisely control the motor rotation direction, and further precisely control the movement of the curtain.

Further, as shown in fig. 27, the second control command is used for triggering the motor to start rotating when the motor is in a rotation stopping state, and responding to the second control command; the method specifically comprises the following steps: the second control instruction is used for triggering the motor to judge whether the duration time of the current rotation stopping state is within a preset time; and continuing to rotate in the rotation direction before stopping rotation in response to the second control instruction when the judgment result is yes, and rotating in the opposite direction of the rotation direction before stopping rotation when the judgment result is no. So that the pressing operation of the knob not only can finely adjust the position of the curtain, but also can realize the opening and closing of the curtain at any position. Specifically, in actual use, a user wants to accurately adjust the window curtain to an expected position, the window curtain can be moved towards the expected direction through rotation operation, when the window curtain approaches to the expected position, the knob pressing operation is applied to the knob pressing operation, the knob pressing operation device sends out a second control instruction to stop the movement of the window curtain, then the pressing operation is applied again within a preset time, the knob pressing operation device sends out the second control instruction again, the window curtain can continue to move along the movement direction before the movement is stopped, when the pressing operation is applied again, the window curtain can move again to stop, and the window curtain is continuously close to the expected position until the expected position is reached. The applicant has found through investigation analysis of a large number of usage scenarios that when the time interval between two pressing operations applied to the knob by the user is longer than the preset time, the user is highly likely to wish not to fine-tune the position of the window shade but to switch the opening and closing of the window shade, and therefore, when the duration of the motor in the stopped rotation state is longer than the preset time, the control method switches the rotation direction of the motor, which is rotated in a direction opposite to the rotation direction before the rotation is stopped. The user can apply the knob pressing operation to open the window curtain, and apply the pressing operation again after the window curtain opening time is longer than the preset time, so as to close the window curtain, and the window curtain can be opened and closed quickly. Further, the preset time is 3 seconds to 1 minute. Further, the preset time is preferably 30 seconds.

Further, as shown in fig. 28, the second control command is used for triggering the motor to be in a rotation stopping state, and responding to the second control command to start rotation; further comprises: the second control instruction is used for triggering the motor to judge whether the motor is currently in an end point interval or not; if so, rotating along the direction opposite to the rotation direction before stopping rotating; if not, continuing to rotate along the rotation direction before stopping rotation. The end point zone may be understood as a zone in which the window covering is in a closed state. In the actual use process, a section of closing interval is reserved near the closing point of the curtain, and the curtain is in a closing state in the closing interval. The reason for such design is that there are some cases where the window curtains cannot reach the closing point due to interference or extrusion force between the window curtains or external reasons, or a small distance is retracted after the window curtains reach the closing point, so that a small distance still exists between the window curtains and the closing point after the window curtains are closed, and at this time, the motor is easy to misjudge that the window curtains are in an open state, so that the knob is pressed again, and the window curtains continue to move towards the closing direction. In order to solve the problem, the method sets the end point interval, wherein the end point interval corresponds to the closing interval of the curtain, and when the motor is positioned in the end point interval, the curtain is considered to be in a closed state, so that misjudgment of the motor on the curtain state is avoided. And further, the phenomenon that the curtain cannot be opened by pressing the knob or the curtain does not act when the curtain is in a closed state is avoided.

Further, the range of the end point interval is smaller than or equal to the range of 2% of a preset stroke, so that the curtain can be closed tightly, and the preset stroke is matched with the maximum opening and closing stroke of the curtain controlled by the curtain motor.

Further, the first control instruction is further configured to cause: after the motor starts to rotate, if other control instructions are not received, the motor continuously rotates to a terminal interval, so that a user can conveniently open or close the curtain through single rotation operation.

Further, the method further comprises the following steps: issuing a third control command in response to the pressing rotation operation to cause the motor to rotate a specified stroke in response to the third control command; the designated stroke is smaller than a maximum opening and closing stroke of a target device controlled by the motor, so that a user can finely adjust the position of the window curtain through a pressing rotation operation. The pressing rotation operation may be understood as a rotation of the knob while pressing the knob, or a rotation of the knob while pressing a key.

Further, as shown in fig. 29, a third control instruction is issued in response to the pressing rotation operation, so that the motor rotates a specified stroke in response to the third control instruction; the method specifically comprises the following steps: if the rotation operation is detected during the duration of the pressing operation, periodically generating and sending out a third control instruction during the duration of the rotation operation, and stopping sending out the third control instruction after the pressing operation and/or the rotation operation is stopped; and the designated travel of the motor indicated by the third control instruction issued in each cycle is the same. That is, the user continuously acts on the knob by pressing the rotation operation, the knob controlling device periodically sends out the third control command, the motor rotates at a constant speed no matter how fast the user rotates the knob, when the user stops rotating the knob or stops pressing the operation, the knob controlling device stops sending the third control command, the motor rotates the designated stroke after receiving the last third control command, and then stops rotating. In a specific embodiment, the specified stroke is set to be a maximum opening and closing stroke of 1/100 of the controlled target device to implement the fine tuning function of the target device.

Further, the sending period of the third control instruction is 50 ms-200 ms. Further, the sending period of the third control command is preferably 100ms, so that the sending period of the third control command can be adapted to the rotation speed of the motor, and the motor can continuously rotate at a constant speed.

According to a fourth aspect of the present utility model, as shown in fig. 30, there is provided a knob control system including a knob controlling apparatus for the above-described control method; and the motor is controlled by the knob control equipment and used for controlling the opening and closing of target equipment. The knob control equipment can be connected with the motor in a wired or wireless mode, so that communication connection is established between the knob control equipment and the motor, and the wired connection mode is preferably power carrier communication connection. Further, the target device comprises a curtain, a window, a door. The knob control device may be a knob wall switch, a knob wireless switch, a knob emitter, or other control device having a knob.
