Description
The invention relates to a divisional application of a high-power-generation rotary wireless passive device, which has the application number of 201911073618.X, the application date of 2019, 11 and 05, and the application type of the device is the invention.
Technical Field
The invention relates to the technical field of switches, in particular to a power generation component of a wireless switch and a power generation control method.
Background
The switch is the most common control device, and the switch can control the connection and disconnection of the circuit, so that the switch has wide application in various industries. Common switches are: pull-cord, toggle, knob, and push-button, among others. Although these switches have a large difference in their shapes, they have a distinct commonality: the wiring installation is necessary, which means that there are some inconveniences in using, such as: line planning must be carried out in advance, and point locations are designed; the process of installation and debugging is time-consuming and labor-consuming, and once the installation is wrong or irregular, the result is hard to imagine; when the space is subjected to reconstruction, the space needs to be refitted and wired again; the higher cost and lack of flexibility … … as industrial control and sensing technology evolves, various sensor and control switch applications become more common. Conventional sensors and switch products need to transmit signals through signal lines and/or supply power through power lines to work normally.
However, in many practical applications, where wiring is either substantially impossible or very expensive due to environmental constraints, wireless sensing and control techniques are desirable. However, wireless technology only solves the problem that no signal line is needed, but energy is also needed, so that batteries are often used for supplying power to the wireless sensor and the switch in places where power lines cannot be distributed. The batteries have a limited service life and need to be replaced frequently, which increases the use and maintenance cost and often causes the system to fail to work normally due to untimely replacement. Since the sensors and control switches used in daily life are relatively small in size and power consumption, it is usually considered to collect mechanical energy such as pressure or light energy in the surrounding environment and convert the mechanical energy into electric energy to supply power to the sensors and control switches. In the aspect of light energy collection, because the indoor illumination intensity of the sensor and the control switch is possibly insufficient, the area of the light energy battery plate is limited by the volume of the whole sensor and the switch, and the use effect in partial places is not ideal. In the aspect of mechanical energy collection, attempts have also been made to develop a wireless passive switch by using the principle that piezoelectric ceramics are deformed by external force, thereby generating current and voltage. However, piezoelectric ceramic technology is more limited because it is more expensive and the current and voltage generated by stacking the piezoelectric ceramics are usually not enough to drive the switch circuit. Mechanical energy generation technology based on the conductive coil electromagnetic induction principle can generate enough current or voltage, but if a traditional coil and rotor structure is adopted, the generator is relatively large in size and is generally not suitable for application of a miniaturized sensor or a flat control switch.
At present, in the field of indoor lighting control all over the world, 86-type seesaw type wired switches installed on walls are mainly adopted to control the on and off of lamps, so that the positions of all switches are required to be planned in detail and accurately before indoor decoration, and effective operations such as switch bottom boxes, groove chiseling, PVC pipe pre-embedding, cable penetrating and the like are required to be pre-embedded on the walls, so that time and labor are wasted, materials such as pipelines and the like are wasted, more importantly, if the positions of switch layout are found to be unsatisfactory in later period and need to be moved or changed, wall chiseling and wiring are required to be carried out again, otherwise, the switches cannot be changed, and the switches cannot be installed in places with damp and explosion-proof requirements.
For the above problems, in the prior art, a wireless remote control switch is also used to control the on/off of the lamp, but the wireless remote control switch in the prior art is not generally accepted by the public, and cannot become a mainstream application, and there are many reasons: 1) the use habits of people are difficult to change; 2) the random placement of the common wireless remote control switch can prevent people from finding the switch, and finding the wireless remote control switch when the lamp is switched is a very troublesome task; 3) if the wireless remote control switch is made into a form capable of being fixed on a wall, the battery is troublesome to replace in future, the wireless remote control switch is required to be disassembled for replacement, the battery needs to be replaced regularly, if the battery is not replaced timely after being used for a long time, liquid leakage and corrosion products can occur, harmful substances are generated to pollute the environment, and the reliability is also greatly reduced; these inconveniences prevent the wide application of wireless remote switches in the field of indoor lighting. In addition, a wireless remote control switch has been produced in foreign countries, but the wireless remote control switch generates electricity by adopting up-and-down reciprocating type pressing, has a complex structure, short service life, poor reliability and high price, and cannot be popularized and applied.
The rotary switch is a switch which controls the on-off of a main contact by rotating a handle. The rotary switch has two structural forms, namely a single-pole unit structure and a multi-pole multi-position structure. The single-pole single-position rotary switch is commonly used with a rotary shaft potentiometer in application, and the multi-pole multi-position rotary switch is mainly used for switching working state lines. The rotary switch can be used to replace the rotary pulse generator of the analog function of the traditional resistance potentiometer, the rotary switches are usually applied to the human-computer interface of the instrument front panel and the video control panel, the rotary switch adopts an orthogonal optical encoder as a pure digital device replacing the analog potentiometer, the rotary switches are similar to the traditional or resistance potentiometer in appearance, but the internal structure of the rotary switches is completely digitalized and uses optical technology. Similar to the conventional incremental encoder product, there are two quadrature output signals (channel a and channel B) that can be directly connected to the encoder processing chip. The common band switch and the shift switch of the multimeter are rotary switches, and the structures of the rotary switches are two types: the BBM (Break Before make) contact type is characterized by that in the transposition, the movable contact is firstly disconnected from front contact and then connected to back contact, and between them there is a state of disconnection with both front and back contacts: the other is MBB (make Before Break) contact type, which is characterized in that the movable contact has a state of contacting with both front and rear contacts during transposition, and then the front contact is disconnected and kept in a contact state with the rear contact. The appropriate rotary switch should be selected in the circuit design according to the circuit application and the circuit safety.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the high power generation rotary wireless passive device includes at least a first power generation unit 1 and a second power generation unit 2. In case of applying an external force action to the wireless passive device, the first power generation part 1 and the second power generation part 2 interact with each other to trigger at least one active operation. The interaction between the first power generation section 1 and the second power generation section 2 is synchronized based on the operation when the user turns the wireless passive device. The wireless passive device provided by the invention can trigger the first effective operation and the second effective operation by utilizing the interaction between the first power generation component 1 and the second power generation component 2 to complete the first power generation and the second power generation. The wireless passive device can trigger a third active operation with the second power generation means 2 to complete a third power generation. Wherein the triggered effective operation refers to an operation generated during the interaction of the first power generation component 1 and the second power generation component 2 with each other, which can power the wireless passive device. The efficient operation may be a coupling of one or more of a triboelectric effect, an electrostatic induction effect, a direct piezoelectric effect, and an electromagnetic induction effect.
More wireless passive devices have been proposed in the prior art for the technical problem of how to achieve higher power generation, however, the prior wireless passive devices have always focused on how to generate higher power generation while a user has a single operation, the technical scheme usually focuses on the magnetic flux change caused by the moment of single operation of the user or the piezoelectric deformation caused by the moment of single operation of the user, in practice, the instantaneous high power generation obtained by the technical scheme is all consumed in enhancing the stability of signal transmission, therefore, the implicit condition that is not mentioned in the technical solution but is of great importance lies in that the operated object corresponding to the wireless passive device is in a standby state for a long time, therefore, the transmission signal can be received at any time, but the operated object always consumes electricity to keep the standby state, and the continuous consumption of the electricity is contrary to the low power consumption target of the wireless passive device.
Based on the problem that the existing wireless passive device can not achieve the low power consumption target under the high power generation capacity, the invention is different from the technical scheme that the existing wireless passive device focuses on generating higher power generation capacity while the user operates the wireless passive device once, and the high power generation rotary wireless passive device provided by the invention aims to improve the interaction mode among a plurality of power generation components to provide different intensities of electric quantities required by the wireless passive device to be capable of activating and controlling the operated object step by step, under the setting, the operated object can be in a dormant state for a long time instead of a standby state of continuously consuming the electric quantities, and the operated object in the dormant state is completely free from electric quantity maintenance.
Specifically, at least one first effective operation and at least one third effective operation are simultaneously performed in one hand rotation, so that the power generation amount by the first effective operation and the power generation amount by the third effective operation form an accumulation relationship. Wherein, one hand rotation refers to the process from the time when the user operates the wireless passive device to the time when the user stops rotating the device. Because the first effective operation and the third effective operation are simultaneously completed in the one-time hand rotation process, the generated energy formed by mutual accumulation of the generated energy of the first effective operation and the generated energy of the third effective operation is stronger, and the wireless passive device has better transmitting power and more stable transmitting signals based on the automatic gain control function of the receiver. Under the stable emission signal, it is enough to activate the operated object in the dormant state. Therefore, unlike the prior art scheme of sacrificing the power consumption of the operated object to improve the stability of the transmission signal, the solution of high power generation of the wireless passive device provided by the present invention is to use part of the obtained power generation for preferentially activating the operated object on the basis of improving the existing structure in a small range without increasing the manufacturing cost, and thus, the wireless passive device provided by the present invention is an effective solution with really low power consumption and low cost.
The amount of power generated by the second active operation is generated immediately thereafter and accompanied by the first active operation and the third active operation again. The second active operation is realized in the process from the release of the wireless passive device by the user to the wireless passive reset, namely, the first active operation and the third active operation are followed. In synchronization with this, the second effective operation is accompanied by the second first effective operation and the third effective operation, and a stronger power generation amount is formed by mutual addition of the power generation amounts by the first effective operation, the second effective operation, and the third effective operation, and the wireless passive device has good transmission power and a stable transmission signal based on the automatic gain control action of the receiver. Under the condition that the operated object is already in an activated state, the stable transmitting signal can greatly reduce the interference of stray signals, and further the wireless passive device can be supported to accurately transmit a more complex control signal to the operated object to realize multifunctional control.
The time interval between the second effective operation and the first effective operation and the third effective operation is determined by the user according to the requirement in a single rotation. The first effective operation/the third effective operation and the second effective operation are completed by two rotations in opposite directions in the case of a single operation by the user. And the total stroke of the rotation operations respectively corresponding to the first effective operation/the third effective operation and the second effective operation does not reach 360 °. Meanwhile, for the user, the user can only perceive the "first effective operation/third effective operation" and the "second effective operation" with time intervals in operation, wherein the second effective operation is used for setting the time intervals, and compared with a software implementation mode which consumes more energy and has poor safety, the obtaining of the intervals is realized by separating from the software implementation mode, and is more reliable and durable. Moreover, the setting of the interval can allow the wireless passive device to have at least four operation functions under the single operation of a user, such as: white light illumination/yellow light illumination/daylight color illumination/blinking illumination. Compared with the prior art, in the operation function switching scheme provided by the wireless passive device, either the logic operation of repeatedly pressing/rotating/sliding is adopted, or the software implementation mode is relied on, the former scheme can cause the reduction of the switch service life under the long-term repeated relative motion, the latter scheme is based on the software technology, has the software error which is difficult to eliminate, so that the reliability is poor, and the fixed environment of long-time work is not facilitated under the condition that the software version is too old or damaged, so that the network cannot be normally acquired or the software cannot be updated. The inventive solution proposed by the present invention to implement time intervals by means of a mechanical structure to configure the switching function while bringing signals required for the switching operation is not described in any of the documents before the present invention was made, nor is there any motivation for the skilled person to make the above improvements to the mature existing wireless passive devices based on the existing multi-operation switches and software programming solutions.
Specifically, for example, when the user operation is set in advance, the wireless passive device is set to be turned on within 1 second by rotating once, and/or the wireless passive device is set to enter the color switching mode by rotating once and being released within 3 seconds, and/or the wireless passive device is set to be turned off within 5 seconds by rotating once, wherein the corresponding time length is the time interval between the second effective operation and the first effective operation and the third effective operation, the wireless passive device in the rotating state is selectively held based on the requirement of the user during single rotation, the control on the wireless passive device is released until the corresponding time length is reached, and the wireless passive device transmits the obtained corresponding operation instruction to the operated object to realize corresponding function control. Different from the prior art, although the conventional wireless passive device realizes the function control of the operated object according to different operations of the user, the technical scheme focuses on identifying and controlling the combination of the rotation operations of the user for different times, namely, only a single function can be realized under a single rotation operation, for example, the brightness of the operated object is improved when the device is continuously rotated twice or the operated object is started when the device is rotated once, and the limited operation mode of the wireless passive device causes the function which can be realized by the operated object to be limited. Therefore, the technical scheme of the wireless passive device provided by the invention for improving the interaction mode among the plurality of power generation components not only solves the technical problem that the continuous consumption of the electric quantity is contrary to the low power consumption target of the wireless passive device in the prior art, but also enriches the functions of the operated object in the interaction mode.
The wireless passive device comprises a plurality of power generation bodies and a plurality of piezoelectric sheets, wherein the plurality of power generation bodies and the plurality of piezoelectric sheets are arranged on the wireless passive device, and the plurality of piezoelectric sheets are arranged on the wireless passive device. Preferably, when the operated object is in the color switching mode, the user operation may be set in advance, for example, the wireless passive device that rotates twice in a short time continuously is set as a parameter for switching the operated object, such as a color, and/or the wireless passive device that rotates once in a short time continuously is set as a color switching mode for ending the switching of the operated object. Further, the interaction mode among the power generation components is beneficial for users to customize rich corresponding relations between the operation of the users and the functions of the operated objects.
According to a preferred embodiment, the second effective operation is performed based on potential energy converted from kinetic energy provided by the first effective operation and the third effective operation. The third effective operation is in a trigger state throughout the power generation from the wireless passive device start-up to the wireless passive device shut-down based on the linkage relationship between the second power generation means 2 and the wireless passive device. Wherein the wireless passive device is capable of activating a signal path between the wireless passive device and the operated object under the first power generation and the third power generation which are accumulated based on a single rotation of a user when the operated object corresponding thereto is in a sleep state. The wireless passive device is capable of maintaining continuous activation of the signal path at a third power generation based on a third active operation that is always in a trigger state. The wireless passive device can transmit signals under the first power generation, the second power generation and the third power generation which are accumulated based on the releasing action after the user rotates.
Preferably, the at least one first effective operation and the at least one third effective operation are simultaneously completed in one hand rotation, and simultaneously, although the second effective operation is synchronously performed, since the speed of the user in a single hand rotation operation is slow, the conductor cutting speed in the second effective operation based on the electromagnetic induction effect is small, so that the second power generation obtained by the second effective operation is small and negligible. In contrast, when the user releases the wireless passive device and makes it quickly rotate backward in a manner of releasing elastic potential energy, the conductor cutting speed in the second effective operation based on the electromagnetic induction effect is faster, so that the second power generation obtained by the second effective operation is greatly increased. The generated energy associated with the first effective operation and the third effective operation is combined, so that the electric energy obtained when the wireless passive device rapidly turns back is greatly increased.

According to a preferred embodiment, the first power generation component 1 has a hollow interior. The second power generation component 2 can be connected to the first power generation component 1 through the hollow inner cavity in a nested manner in such a way that it can rotate relative to the first power generation component 1. At least two inner walls having different polarities are arranged in a radial extending direction of the inner wall of the first power generation member 1. For example, two non-adjacent 1/4 have their inner circumferential wall N-polar and two other non-adjacent 1/4 have their inner circumferential wall S-polar. The first power generation component 1 is used for providing a magnetic field intersecting with the second power generation component 2 so that the magnetic induction wire cutting component 6 can generate power by utilizing the electromagnetic induction effect. The magnetically inductive wire cutter 6 may be a metal frame disposed outside the second power generation piece 4. The metal frame generates electricity by cutting the magnetic induction lines.
According to a preferred embodiment, the second power generation component 2 comprises at least a hollow inner cavity thereof and at least one cantilever beam provided in the hollow inner cavity by means of an elastic connection. At least one third power generation piece 5 is arranged on the cantilever beam. The rotary wireless passive device causes the cantilever beam to rotate relative to the inner wall of the second power generation part 2 by an external load applied thereto. The cantilever beams interact with each other with the second power generation means 2 in such a way that they correspond alternately to different magnetic areas on the second power generation means 2. The cantilever beam enables the at least one third power generation sheet 5 to generate forced bending deformation in a mode of storing or releasing elastic potential energy under the interaction. The forced bending deformation based on the third power generation sheet 5 triggers a second effective operation, and the second effective operation converts the mechanical energy provided by the forced bending deformation into a second power generation output to the outside. Preferably, the cantilever beam is arranged on the shaft inside the second power generation part 2 with one end thereof being a free end. The rotating shaft is rotationally connected with the housing of the second power generation component 2 without mutual influence, and the rotating shaft extends out of the housing and is fixedly connected to the inner wall of the housing of the wireless passive power generation device to move synchronously.
According to a preferred embodiment, the cantilever beams comprise at least a first 7 and a second 8 cantilever beam along a plane perpendicular to the rotation plane of the rotating wireless passive device. At least one third power generation piece 5 is arranged between the first cantilever beam 7 and the second cantilever beam 8. Wherein the third power generating strip 5 can be in a flat state in a case where the first cantilever beam 7 and the second cantilever beam 8 alternately correspond to different magnetic regions on the second power generating member 2, respectively, or in a piezoelectric state in a manner that the first cantilever beam 7 and the second cantilever beam 8 elastically deform toward directions close to each other, respectively. As shown in fig. 1, at least one magnet is disposed on an inner wall of the housing of the second power generation component 2, and the magnet above the inner wall has a magnetic property opposite to that of the magnet below the inner wall. At least one magnet is arranged on the first cantilever beam 7 close to the upper part of the inner wall of the shell of the second power generation component 2, and one end surface of the magnet close to the inner wall of the shell has the same magnetism as the magnet above the inner wall and repels the magnet.

When the first cantilever beam 7 and the second cantilever beam 8 respectively repel each other with the inner wall of the shell of the second power generation component 2, the distance between the first cantilever beam 7 and the second cantilever beam 8 is rapidly close to but not attached to each other due to the repulsive force acting in the vertical direction and the mutual attractive force between the first cantilever beam 7 and the second cantilever beam 8. At least one third power generation sheet 5 positioned on the first cantilever beam 7 and the second cantilever beam 8 is forced to be elastically deformed and is in a piezoelectric state to output electric potential energy outwards. Meanwhile, as the distance between the first cantilever beam 7 and the second cantilever beam 8 is sharply close, the first cantilever beam 7 and the second cantilever beam 8 are respectively elastically bent, so that at least one power generation piece 5 positioned on the first cantilever beam 7 and the second cantilever beam 8 is elastically deformed to be in a piezoelectric state and output electric potential energy outwards. When the rotating shaft in the second power generation component 2 rotates relative to the housing, at least one magnet is arranged on the first cantilever beam 7 close to the upper part of the inner wall of the housing of the second power generation component 2, and one end surface of the magnet close to the inner wall of the housing is different from the magnet above the inner wall in magnetism and mutually attracts.

Thereby causing the first and second cantilevered beams 7 and 8, respectively, that are close to each other to move away from each other. And the first cantilever beam 7 or the second cantilever beam 8 cannot be attracted to the inner wall of the housing of the second power generation component 2 due to the length limitation of the at least one power generation piece 5 positioned on the first cantilever beam 7 and the second cantilever beam 8.
According to a preferred embodiment, the first power generating component 1 is configured to rotate together with the wireless passive device with respect to the device base in such a manner that the second coil spring 9 connected to the wireless passive device is wound to store elastic potential energy when an external load is applied to the wireless passive device to rotate it with respect to the device base.
