At present, batteries are required to be used as power supplies of wireless switches used in the market, most of the batteries cannot be reused, the service life of the wireless switches is short, and if the wireless remote controller is used for a long time, the batteries must be purchased circularly for replacement, so that the economic burden of a user is increased; secondly, the manufacturing of the battery consumes resources, and according to the fact that experts call the damage of the battery, one button battery can pollute 60 thousands of liters of water; one battery is rotten in the ground, so that the utilization value of ten thousand square meters of land can be lost. In recent years, measures for saving energy, reducing consumption and protecting environment are pushed to the utmost in all countries around the world, and thus the protection of the environment is a very slow matter. Therefore, there are many wireless switches capable of generating power in the prior art. Meanwhile, the wireless passive switch can be divided into a plurality of different types according to the power generation principle of the power generation module. The self-generating mode mainly comprises a piezoelectric mode, an electrostatic mode, an electromagnetic mode and a photovoltaic mode.

For example, patent document No. CN107132795A discloses a self-generating wireless switch, which includes a micro-generator and a control board for sending wireless control signals to the outside; the micro generator comprises a magnet group and a coil group, wherein the magnet group is movably arranged, the coil group comprises an iron core and a lead which is electrically connected to the control board, and the lead is wound outside the iron core to form a coil; the magnet group is arranged on the outer side of the coil group and is arranged opposite to the central line of the coil, and the magnet group comprises a permanent magnet and magnetic conduction plates respectively arranged on two opposite sides of the permanent magnet. According to the self-generating wireless switch, mechanical energy is converted into electric energy by operating the magnet group to move up and down, so that the effects of providing power for the control board by self-generating electricity and sending a wireless control signal to the outside are achieved; the remote control switch has the advantages of better reliability, safety, convenience for remote control, no need of using a chemical battery, waste and environmental pollution prevention, no need of wiring, cost saving, convenience for layout, simple structure and wide popularization and application in life.

For example, patent document No. CN110033969A discloses a self-generating wireless switch, which includes a base, a button, a circuit board, and a power generation module, where two opposite sides of the power generation module are respectively provided with a touch power generation switch elastic sheet, the base is symmetrically provided with a pair of pressing arms independent from each other, each pressing arm includes a connecting portion and a supporting portion, the end of the connecting portion is pivoted with the base, and the supporting portion is arranged between the button and the touch power generation switch elastic sheet; the base is also provided with a gland; both ends of the button can rotate around the second rotating shaft. According to the embodiment of the invention, the elastic parts are respectively arranged below the two ends of the button, so that the two ends of the button are subjected to the same reaction force of the elastic parts when being pressed, the pressing force is consistent when the two ends of the button are pressed, and the heights of the two ends of the button are kept consistent when the button rebounds under the action of the elastic parts through the pair of mutually independent pressing arms and the pressing covers for limiting the rotation amplitude of the pressing arms which are symmetrically arranged.

To sum up, current from generating electricity wireless switch presses the button through the hand in order to input the power generation module with kinetic energy, and then makes the power generation module turn into the electric energy with kinetic energy. When the hand stops pressing the button, the power generation module stops working immediately, so that the wireless control signal stops being sent immediately, namely the sending time of the whole wireless control signal is short, and the normal receiving of the electric appliance cannot be guaranteed.

Example 1

As shown in fig. 1, the present invention provides a seesaw type self-generating device with an extended signal duration, which at least comprises a self-generating module 1, an external force receiving module 2 and a signal forwarding module 3. When an operator presses the external force receiving module 2, the external force receiving module 2 can receive mechanical energy applied by the operator and convert the mechanical energy into kinetic energy. The self-generating module 1 can be coupled with the external force receiving module 2, so that the self-generating module 1 can receive kinetic energy generated by the external force receiving module 2 and further generate electricity, wherein the self-generating module 1 can respond to the kinetic energy with difference to form different working states, so that the self-generating module 1 can at least generate electric energy A and electric energy B with different characteristics, and further can prompt the signal forwarding module 3 to send different control commands through the electric energy with different characteristics. The signal repeating module 3 can be electrically connected with the self-generating module 1 so that the signal repeating module 3 can receive the electric power generated from the self-generating module 1. The signal forwarding module 3 can respond to the received electric energy and send the pre-stored control command to the designated electric appliance 4, so that the electric appliance 4 can work according to the established state matched with the control command. For example, the signal forwarding module 3 pre-stores a first control command for controlling the electrical appliance to be turned on and a second control command for controlling the electrical appliance to be turned off. The signal forwarding module 3 can be controlled to select a proper control command to control the electric appliance 4 to be in a required working state through the electric energy A and the electric energy B generated by the external force receiving module from the power generation module 1, and finally one-to-one control of the electric appliance 4 is realized. I.e. one self-generating device is able to control the operating state of one appliance 4. For example, the signal forwarding module 3 can recognize the power a and further send a first control command to the electrical appliance 4, so that the electrical appliance 4 is in an on state. Or, the signal forwarding module 3 can recognize the B electric energy, and then send the second control command to the electrical appliance 4, so that the electrical appliance 4 is in a closed state. It will also be understood that, as shown in fig. 3, different control commands for controlling the operation of several different electrical appliances 4 can also be provided in the signal forwarding module 3. For example, by setting the plurality of external force receiving modules 2, the self-generating module 1 can generate electric energy with different characteristics in response to different external force receiving modules 2, and then the signal forwarding module 3 can select a corresponding control command according to the characteristics of the electric energy and send the control command to the corresponding electrical appliance 4. That is, each external force receiving module 2 individually controls one electric appliance 4, and thus the electric appliance 4 can be brought into different operating states in response to different control commands. Finally, one-to-many control of the electric appliance 4 is realized.

Preferably, referring again to fig. 1, the self-power generation device further includes a first body 5 capable of accommodating the self-power generation module 1 and the external force receiving module 2. The first body 5 can have a first housing cavity 6. Both the self-generating module 1 and the external force receiving module 2 may be disposed in the first receiving cavity 6. Specifically, the first body 5 includes at least a first case 5a and a second case 5 b. The first case 5a and the second case 5b can be integrally molded to collectively constitute the first body 5. The shapes of the first case 5a and the second case 5b can each be defined by a hollow cylindrical shape. Both end portions of the first housing 5a are open. One end of the second case 5b is open, and the other end of the second case 5b is closed. The first case 5a and the second case 5b can be connected to each other in such a manner that their respective central axes coincide with each other. For example, as shown in fig. 1, the lower end of the first housing 5a can be brought into abutting contact with the upper end of the second housing 5 b. Both the upper end and the lower end of the first housing 5a can be open. The upper end of the second housing 5b is open-shaped, and the lower end of the second housing 5b is closed-shaped, so that the second housing 5b can communicate with the first housing 5a to define a first accommodation chamber 6 together.

Preferably, again with reference to fig. 1, the self-generating device further comprises a second body 7 able to be snapped to the first body 5. The second body 7 can have a second receiving cavity 8, such that the signal forwarding module 3 can be disposed in the second receiving cavity 8. The shape of the second body 7 can be defined by a hollow cylinder. One end of the second body 7 may be open. The other end of the second body 7 can be closed. The closed end of the second body 7 can be clamped to the second housing 5b, so that the first body 5 and the second body 7 can be integrated when the self-generating device is used, and the self-generating device can be conveniently used. Specifically, as shown in fig. 1, the outer diameter of the first housing 5a can be substantially equal to the outer diameter of the second body 7, and the outer diameter of the second housing 5b can be smaller than the outer diameter of the second body 7. A cylindrical fixing groove 9 is provided at the closed end of the second body 7. The inner diameter of the fixing groove 9 can be matched with the outer diameter of the second housing 5b so that the second housing 5b can be inserted into the fixing groove 9. Preferably, an inner thread may be provided on an inner wall of the fixing groove 9, and an outer thread may be provided on an outer wall of the second housing 5b, so that the reliability of the connection of the second housing 5b with the second body 7 may be improved by the cooperation of the inner thread and the outer thread.

Preferably, referring again to fig. 1, a first wire guide hole 10 is provided in the second housing 5 b. The fixing groove 9 is provided with a second wire guide hole 11. The first accommodating cavity 6 and the second accommodating cavity 8 can be communicated with each other through a first wire guide hole 10 and a second wire guide hole 11 in sequence, so that the self-generating module 1 in the first body 1 can be connected with the signal forwarding module 3 in the second body 5 through a cable, for example. A sealing cover 12 may be provided on one end of the second body 7 having an open shape. The sealing cover 12 can be nested in the second accommodating cavity 8. Preferably, the outer wall of the sealing cover 12 can be provided with an external thread. The inner wall of the second receiving chamber 8 may be provided with an internal thread. And can be screwed to the second receiving chamber 8 by means of the sealing cover 12.

Preferably, referring again to fig. 1, the signal forwarding module 3 at least includes a communication main board 3a and a signal enhancing antenna 3 b. The signal booster antenna 3b can be electrically connected to the communication main board 3 a. The communication main board 3a can be electrically connected to the self-generating module 1. The pre-stored control command can be wirelessly transmitted to the electric appliance 4 through the signal enhancing antenna 3b through the communication main board 3 a. The signal enhancing antenna 3b can enhance the signal coverage of the communication main board 3a so that it has a longer communication distance.

Preferably, referring again to fig. 1, the self-generating module 1 includes at least a self-generating assembly 1a, a first power transmission assembly 1b, and a second power transmission assembly 1 c. The first power transmission assembly 1b and the second power transmission assembly 1c are used for transferring kinetic energy generated by the external force receiving module 2 to the self-generating assembly 1a, so that the self-generating assembly 1a can generate electric energy with different characteristics. For example, a phase difference can be provided between the a electric power generated by the first power transmission assembly 1B and the B electric power generated by the second power transmission assembly 1B. And then the electric energy A can trigger the signal forwarding module 3 to transmit the first control command to the electric appliance 4, so that the electric appliance 4 is started. Or the B electric energy can trigger the signal forwarding module 4 to transmit the second control command to the electric appliance 4, thereby realizing the turning off of the electric appliance 4.

Preferably, referring again to fig. 1, the self-generating assembly 1a includes at least a generating motor 13 and a third meshing gear 14. The self-generating module 1a can be disposed in the second housing 5 b. The axial direction of the third meshing gear 14 can be substantially perpendicular to the axial direction of the second housing 5 b. The generator motor 13 may be an electromagnetic generator that generates an induced current by cutting magnetic induction wires. The generating motor 13 can be coaxially connected with the third meshing gear 14, so that the third meshing gear 14 can drive the generating motor 13 to rotate when rotating. When the first power transmission assembly 1b is operated, it can drive the third meshing gear 14 to rotate, for example, in a clockwise direction, thereby generating electric energy a. When the second power transmission assembly 1c is operated, it can drive the third meshing gear 14 to rotate in, for example, a counterclockwise direction, thereby generating B electric power. It can be understood that the characteristics of the electric energy only act on the signal forwarding module 3 to distinguish and identify the electric energy, so that the signal forwarding module 3 can select the control command corresponding to the electric energy to transmit. Therefore, the characteristics of the electric energy are not limited to the phase difference. The characteristics of the electrical energy may also be defined by, for example, the duration of the electrical energy, the magnitude of the electrical current, etc. That is, different operating states from the power generation module 1 refer to different power generation modes resulting from different rotational directions of the third meshing gear 14.

Preferably, referring to fig. 1 again, the self-generating module 1 further includes a self-generating assembly 1a and a first engaging rack 15 which are engaged and linked with each other. In a case where the external force receiving module 2 and the self-generating module 1 are in the second operation state, and the external force receiving module 2 is applied with mechanical energy, the first engaging rack 15 can move at a first speed in the first direction in response to the kinetic energy input from the external force receiving module 2, wherein, in a case where the external force receiving module 2 is continuously applied with mechanical energy such that the external force receiving module 2 and the self-generating module 1 are in the third operation state, the first engaging rack 15 can move at a second speed greater than the first speed in a second direction opposite to the first direction based on the release of elastic potential energy, or the external force receiving module 2 and the self-generating module 1 are in the second operation state, and the external force receiving module 2 is applied with mechanical energy, the first engaging rack 15 can move at the second speed in the second direction in response to the kinetic energy input from the external force receiving module 2, wherein, under the condition that the mechanical energy is continuously applied to the external force receiving module 2 so that the external force receiving module 2 and the self-generating module 1 are in the third working state, the first engaging rack 15 can move at the second speed in the first direction based on the release of the elastic potential energy. The self-generating assembly 1a generates a electric energy in a case where the first engaging rack 15 moves in the first direction, or generates B electric energy in a case where the first engaging rack 15 moves in the second direction. Specifically, the self-generating module 1 further includes a first power transmission assembly 1b connected to a first end 15a of the first meshing rack 15 and a second power transmission assembly 1c connected to a second end 15b of the first meshing rack 15. In the case that the external force receiving module 2 and the self-generating module 1 are in the second working state, and the first engaging rack 15 moves along the first direction, the first power transmission assembly 1b can store the first elastic potential energy in the first form, and the second power transmission assembly 1c can store the second elastic potential energy in the second form, wherein, in the case that the external force receiving module 2 and the self-generating module 1 are switched from the second working state to the third working state, the first power transmission assembly 1b can push the first engaging rack 15 to move along the second direction, and the second power transmission assembly 1b can pull the second engaging rack 15 to move along the second direction, or in the case that the external force receiving module 2 and the self-generating module 1 are in the second working state, and the first engaging rack 15 moves along the second direction, the first power transmission assembly 1b can store the second elastic potential energy, the second power transmission assembly 1c can store a first elastic potential energy, wherein, when the external force receiving module 2 and the self-generating module 1 are switched from the second working state to the third working state, the first power transmission assembly 1b can pull the first engaging rack 15 to move along the first direction, and the second power transmission assembly 1b can push the second engaging rack 15 to move along the first direction. As shown in fig. 1, the first direction may be a horizontal left direction and the second direction may be a horizontal right direction. The first form of the first elastic potential energy refers to the elastic potential energy of the compression spring 16c formed as a result of being compressed. The second form of second elastic potential energy is elastic potential energy formed by the compression spring 16c as a result of being stretched.

Preferably, each of the first power transmission assembly 1b and the second power transmission assembly 1c includes at least a first energy storage portion 16, a second energy storage portion 17, and a connecting cord 18. The second energy storage part 17 can be in meshed linkage with the external force receiving module 2 to receive kinetic energy, wherein the second energy storage part 17 can pull the first meshed rack 15 to move in the first direction or the second direction through the connection rope 8 in response to the kinetic energy, so that the first energy storage part 16 can store the first elastic potential energy and/or the second elastic potential energy based on the movement of the first meshed rack 15. Specifically, the first engaging rack 15 can engage with the third engaging gear 14, and the third engaging gear 14 can rotate when the first engaging rack 15 moves in the set direction. For example, as shown in fig. 1, when the first meshing rack 15 moves rightward, the third meshing gear 14 can rotate clockwise. When the first engaging rack 15 is moved leftward, the third engaging gear 14 can be rotated counterclockwise. The first energy storage portion 16 corresponding to the first power transmission assembly 1b can be connected to the first end 15a of the first engaging rack 15. The first energy storage portion 16 corresponding to the second power transmission assembly 1c can be connected with the second end 15b of the first engaging rack 15. When the first engaging rack 15 moves leftward, the first energy storage portion 16 corresponding to the first power transmission assembly 1b can be compressed to store elastic potential energy, and the first energy storage portion 16 corresponding to the second power transmission assembly 1c can be stretched to store elastic potential energy. Or, when the first engaging rack 15 moves rightward, the first energy storage portion 16 corresponding to the first power transmission assembly 1b can be stretched to store elastic potential energy, and the first energy storage portion 16 corresponding to the second power transmission assembly 1c can be compressed to store elastic potential energy. The first end 15a of the first engaging rack 15 is connected to the second energy storage portion 17 corresponding to the first power transmission assembly 1b through the connecting rope 18 corresponding to the first power transmission assembly 1 b. The second end 15b of the first engaging rack 15 is connected to the second energy storage portion 17 corresponding to the second power transmission assembly 1c through the connecting rope 18 corresponding to the second power transmission assembly 1 c. When all the first energy storing portions 16 are in the non-energy storing state, all the second energy storing portions 17 are in the energy storing state. The first engagement rack 15 is movable in a first direction or a second direction to define a first position, a second position and a third position. Specifically, as shown in fig. 1, for convenience of description, an extreme position where the first engaging rack 15 is located on the left side of the third engaging gear 14 is defined as a first position, a position where the first engaging rack 15 is located in the middle of the third engaging gear 14 is defined as a second position, and an extreme position where the first engaging rack 15 is located on the right side of the third engaging gear 14 is defined as a third position. When the first engaging rack 15 is in the second position, all of the first energy storing portions 16 are in the non-charged state, and all of the second energy storing portions 17 are in the charged state. For example, as shown in fig. 1 and 2, the second energy storing portion 17 includes at least a rotary shaft 17a, a meshing tooth 17b, and a coil spring 17 c. The first body 5 is provided with a fixing hole 19 therein. A coil spring 17c can be disposed in the fixing hole 19 and a rotation shaft 17a can be rotatably disposed in the fixing hole 19, wherein both end portions of the coil spring 17c are connected to the inner wall of the fixing hole 19 and the rotation shaft 17a, respectively, and thus when the rotation shaft 17a rotates, the degree of curling of the coil spring 17a can be increased to store elastic potential energy, thereby causing the second energy storing portion 17 to assume an energy storing state. The spiral directions of the two coil springs 17c are arranged in a mutually opposite manner. For example, the spiral direction of the coil spring 17c corresponding to the first power transmission assembly 1b is the clockwise direction. The spiral direction of the coil spring 17c corresponding to the second power transmission assembly 1c is counterclockwise. When the rotary shaft 17a corresponding to the first power transmission assembly 1b is rotated counterclockwise, the degree of curling of the coil spring 17c corresponding thereto is increased, and the connecting cord 18 corresponding thereto can be wound around the rotary shaft 17a, thereby enabling the first engaging rack 15 to be moved from the second position to the first position. The movement of the first engaging rack 15 can drive the rotating shaft 17a corresponding to the second power transmission assembly 1c to rotate clockwise, so that the curling degree of the coil spring 17c corresponding to the second power transmission assembly 1c is increased. Alternatively, when the rotary shaft 17a corresponding to the second power transmission assembly 1c is rotated clockwise, the degree of curling of the coil spring 17c corresponding thereto is increased, and the connecting cord 18 corresponding thereto can be wound around the rotary shaft 17a, so that the first engaging rack 15 can be moved from the second position to the first position. The movement of the first engaging rack 15 can drive the rotating shaft 17a corresponding to the first power transmission assembly 1c to rotate counterclockwise, so that the curling degree of the coil spring 17c corresponding to the first power transmission assembly 1c is increased. That is, during the leftward or rightward movement of the first engaging rack 15, all the coil springs 17c can be in a power accumulating state, and thus all the connecting cords 18 can be in a tightened state.

Preferably, referring again to fig. 1, the first energy storage portion 16 includes at least a mounting seat 16a, a web 16b and a compression spring 16 c. The shape of the mount 16a can be defined by a hollow cylindrical shape. Both end portions of the mounting seat 16a can be opened. The web 16b can be nested in the mounting seat 16 a. Both ends of the compression spring 16a are connected to the web 16b and the first meshing rack 15, respectively. The web 16b is provided with a through hole 20 so that the connecting string 18 can be inserted through the through hole 20 to be nestingly arranged in the mounting seat 16 a. It will be appreciated that several guide wheels 21 may be provided in order to arrange the running direction of the connecting cord 18, whereby the running direction of the connecting cord 18 can be changed by means of the guide wheels 21.

Preferably, referring again to fig. 1, the external force receiving module 2 includes at least a first engaging gear 2a, a second engaging gear 2b, a second engaging rack 2c, a third engaging rack 2d, a first driving body 2e, and a second driving body 2 f. The first meshing gear 2a can mesh with the second energy storage portion 17 corresponding to the first power transmission assembly 1 b. The second meshing gear 1b can mesh with the second energy storage portion 17 corresponding to the second power transmission assembly 1 c. In the case where the first engaging gear 2a is actively rotated in the third direction, the length of the connecting string 18 corresponding to the first power transmission assembly 1b can be decreased so that the first engaging rack 15 can be moved in the first direction, and the length of the connecting string 18 corresponding to the second power transmission assembly 1c can be increased to bring the second engaging gear 2b into rotation in the fourth direction opposite to the third direction, or in the case where the second engaging gear 2b is actively rotated in the fourth direction, the length of the connecting string 18 corresponding to the second power transmission assembly 1c can be decreased so that the first engaging rack 15 can be moved in the second direction, and the length of the connecting string 18 corresponding to the first power transmission assembly 1b can be increased to bring the first engaging gear 2a into rotation in the third direction. Specifically, as shown in fig. 1, the third direction may be a clockwise direction. The fourth direction may be a counterclockwise direction. Both the first drive body 2e and the second drive body 2f are slidably provided in the first body 5, and the first drive body 2e or the second drive body 2f is slidable in the axial direction of the first body 5 when the first drive body 2e or the second drive body 2f receives a thrust force applied from the outside. For example, the first and

second driving bodies

2e and 2f are provided with the protrusions 22. The inner wall of the first body 5 is provided with a sliding groove 23. When the protrusion 22 is received in the sliding groove 23, the first driving body 2e or the second driving body 2f can slide along the extending direction of the sliding groove 23. The second engaging rack 2c is disposed on the first driving body 2 e. The third engaging rack 2d is disposed on the second driving body 2 f. The respective extending directions of the second and third racks of

engagement

2c and 2d are substantially parallel to the axial direction of the first body 5. The first engaging gear 2a and the second engaging gear 2b are both provided in the first body 5, wherein the engaging teeth 17b corresponding to the first power transmission portion 1b can be engaged with the first engaging gear 2a, and the engaging teeth 17b corresponding to the second power transmission portion 1c can be engaged with the second engaging gear 2 b. The first meshing gear 2a can also mesh with the second meshing rack 2c, and the second meshing gear 2b can also mesh with the third meshing rack 2 d. By pushing the first driving body 2e downward, the second engaging rack 2c can be driven to move downward, and finally the first engaging gear 2a is driven to rotate by the movement of the second engaging rack 2 c. Alternatively, the third engaging rack 2d can be driven to move downward by pushing the second driving body 2f downward, and finally the second engaging gear 2b is driven to rotate by the movement of the third engaging rack 2 d.

Preferably, referring again to fig. 1, the external force receiving module 2 further includes a mounting plate 2g, a first return spring 2h, and a second return spring 2 i. The mounting plate 2g is fixedly disposed in the first body 5. The first and second return springs 2h and 2i are both provided on the mounting plate 2g, wherein the first return spring 2h is connected to the first driving body 2e, and the second return spring 2i is connected to the second driving body 2 f. When the first driving body 2e moves downward, it can compress the first return spring 2h, thereby enabling the first return spring 2h to take a compressed state. Alternatively, when the second driving body 2f moves downward, it can compress the second return spring 2i, thereby allowing the second return spring 2i to take a compressed state. The first and

second driving bodies

2e and 2f can be automatically moved upward to be restored to their original positions after the external force is removed by providing the first and second return springs 2h and 2 i.

Preferably, referring again to fig. 1, the external force receiving module 2 further includes a rocker button 2 j. One end of the seesaw button 2j abuts against and contacts the first driving body 2e, and the other end thereof abuts against and contacts the second driving body. The rocker button 2j can be hinged to the first body 5. For example, the first body 5 may be provided with a mounting hole. A through hole may be provided on rocker button 2 j. The rocker button 2j can be rotated about its through hole by inserting the rotation shaft into the mounting hole and the through hole at the same time. The first driving body 2e can be moved in the set direction in case the rocker button 2j is rotated in the fourth direction, or the second driving body 2f can be moved in the set direction in case the rocker button 2j is rotated in the third direction. For example, when the rocker button 2j is rotated counterclockwise, the left end thereof can push the first driving body 2e to move downward, or when the rocker button 2j is rotated clockwise, the right end thereof can push the second driving body 2f to move downward. The difference of kinetic energy generated by the external force receiving module 2 is used for distinguishing different working states of the external force receiving module 2. For example, the first driving body 2e can generate the first kinetic energy when moving downward, thereby allowing the self-generating module 1 to generate the first electric energy. The second driving body 2f can generate second kinetic energy when moving downward, thereby enabling the self-generating module 1 to generate second electric energy.

Preferably, the signal forwarding module 3 is configured to transmit the control command as follows:

s1: when the external force receiving module 2 is disposed at the first operating position so as to be in the first operating state separated from the self-generating module 1, mechanical energy is applied to the external force receiving module 2, so that the external force receiving module 2 can move a first set distance in a set direction to be located at the second operating position, and thus the external force receiving module 2 and the self-generating module 1 can be switched from the first operating state to the second operating state in contact with each other, wherein in the process of switching the first operating state to the second operating state, the self-generating module 1 can be in the operating state in which electric energy is not generated, so that the signal forwarding module 3 is in the power-off state.

Specifically, as shown in fig. 1, when the external force receiving module 2 is in the first working position, the second engaging rack 2c and the first engaging gear 2a are in a separated state, and the third engaging rack 2d and the second engaging gear 2b are in a separated state. The set direction may be a vertically downward direction. In the second operating position, the second engaging rack 2c is in a state of just contact with the first engaging gear 2a, or the third engaging rack 2d is in a state of just separation from the second engaging gear 2 b.

S2: continuing to apply mechanical energy to the external force receiving module 2, enabling the external force receiving module 2 to continue to move a second set distance in the set direction so as to be located at a third working position, and enabling the external force receiving module 2 and the self-generating module 1 to be switched to a third working state to be separated from each other from the second working state, wherein in the process that the second working state is switched to the second working state, the self-generating module 1 can convert kinetic energy received by the self-generating module into elastic potential energy for storage while generating first electric energy or second electric energy.

Specifically, during the process that the external force receiving module 2 and the self-generating module 1 are switched from the second working state to the third working state, the first engaging rack 15 can move leftwards or rightwards to enable the self-generating module 1 to generate electric energy, meanwhile, the compression spring 16c can store elastic potential energy in a compression or stretching manner, and the coil spring 17c can store elastic potential energy in a curling manner. For example, when the first engaging rack 15 moves leftward, the compression spring 16c corresponding to the first power transmission assembly 1b can be compressed, and the compression spring 16c corresponding to the second power transmission assembly 1c can be extended.

S3: continuing to apply mechanical energy to the external force receiving module 2, so that the external force receiving module 2 and the self-generating module 1 can be switched from the third working state to a fourth working state completely separated from each other, so that elastic potential energy can be released to prompt the self-generating module 1 to continue to generate the first electric energy or the second electric energy, wherein the signal forwarding module 3 can transmit a corresponding control command to the electrical appliance 4 based on the first electric energy or the second electric energy.

Specifically, when the external force receiving module 2 and the self-generating module 1 are separated from each other, the first engaging rack 15 can move based on the elastic potential energy of the compression spring 16c and the coil spring 17c, and further, the power generation motor 13 is driven to generate power.

For ease of understanding, the power generation principle of the self-power generation device of the present invention will be described in detail.

In a case where the self-generating module 1 and the external force receiving module 2 are configured in the second operating state such that the first engaging rack 15 is located at the first position, the second operating state is switched to the third operating state such that the first engaging rack 15 can be moved in the first direction, and thus the first engaging rack 15 can be switched from the first position to the second position; and continuously switching the self-generating module 1 and the external force receiving module 2 from the third working state to the fourth working state, so that the first engaging rack 15 can firstly move in the second direction based on the release of the elastic potential energy and finally stay at the second position after reciprocating at least once between the first position and the third position, wherein the self-generating module 1 can generate the first electric energy or the second electric energy based on the movement and reciprocating movement of the first engaging rack 15. Specifically, when the control device 4 needs to be turned on, a force can be applied to the rocker button 2j to rotate counterclockwise, and the first driving body enables the first driving body 2e to drive the second engaging rack 2c to move downward, wherein when the first driving body 2e is at the initial position, the second engaging rack 2c and the first engaging gear 2a are in a state of being separated from each other. When the second engaging rack 2c moves downwards for a first set distance, the second engaging rack 2c can be engaged with the first engaging gear 2a, and further when the second engaging rack 2c continues to move downwards for a second set distance, the first engaging gear 2a can be driven by the second engaging rack 2c to rotate clockwise. Subsequently, the rotary shaft 17a corresponding to the first power transmission assembly 1b can be rotated counterclockwise based on the engagement of the meshing teeth 17b with the first meshing gear 2a, thereby causing the degree of curling of the coil spring 17c corresponding to the first power transmission assembly 1b to increase and causing the connecting cord 18 corresponding to the first power transmission assembly 1b to be wound around the rotary shaft 17 a. Finally, the first engaging rack 15 is moved leftward to the first position based on the pulling action of the connecting cord 18 corresponding to the first power transmission assembly 1 b. During the process that the first meshing rack 15 moves from the second position to the first position, the third meshing gear 14 continuously rotates counterclockwise, so that the generator motor 13 can generate electric energy. Meanwhile, the connection string 18 corresponding to the second power transmission assembly 1b can apply a pulling force to the rotation shaft 17a connected thereto, thereby rotating the rotation shaft 17a corresponding to the second power transmission assembly 1b clockwise, wherein the degree of curling of the coil spring 17c corresponding to the second power transmission assembly 1b can be increased based on the clockwise rotation of the rotation shaft 17 a. At this time, the first energy storage portion 16, the second energy storage portion 17, the first return spring 2h, and the second return spring 2i are all in the power storage state.

Subsequently, the first driving body 2e is continuously pressed downward so that the second engaging rack 2c can be disengaged from the first engaging gear 2 a. At this time, based on the elastic potential energy stored in the first energy storage part 16 and the second energy storage part 17, the first engaging rack 15a can move rightward, and then the third engaging gear 14 can rotate clockwise to drive the generator motor 13 to continuously generate electric energy. Due to the elastic potential energy of the first energy storage part 16 and the second energy storage part 17, the first engaging rack 15a will swing back and forth several times between the first position and the third position until the internal forces reach equilibrium. Due to the symmetrical arrangement of the first power transmission assembly 1b and the second power transmission assembly 1c, the first engaging rack 15a will finally stay at the second position after several back and forth swings between the first position and the third position.

Finally, the rocker button 2j is released, and the first driving body 2e moves upward under the action of the elastic potential energy of the first return spring 2h, so that the first driving body 2e can be restored to its original position. At this point, the first driving body 2e drives the self-generating module 1 to generate electricity. Similarly, when the electrical appliance 4 needs to be controlled to be turned off, the second driving body 2f is pressed only by following the above process, so that the first meshing rack 15 drives the third meshing gear 14 to rotate counterclockwise, and the generator motor 13 generates electric energy. For convenience of description, the electric energy generated by the movement of the first driving body 2e is defined as a first electric energy. The electric energy generated by the movement of the second driving body 2f is defined as second electric energy. At this time, the respective characteristics of the first electric power and the second electric power can be defined by the first rotation direction of the third meshing gear 14. That is, the signal forwarding module 3 can recognize the first rotation direction of the third engaging gear 14, and can distinguish the first electric energy and the second electric energy generated from the power generation module 1, and finally transmit the first control command matched with the first electric energy to the electric appliance 4, or transmit the second control command matched with the second electric energy to the electric appliance 4. For example, an a sensor and a B sensor may be provided in the second housing 5B. Two sensors are provided on both sides of one tooth of the third meshing gear 14, respectively. Further, when the third meshing gear 14 rotates counterclockwise, the a sensor first acquires a signal. When the third meshing gear 14 rotates clockwise, the B sensor first acquires a signal.

Through the mode, the following technical effects can be at least achieved: in the conventional non-self-generating device, the revocation operation cannot be performed. Namely, once the button is pressed, electric energy is generated to further trigger the generation of a control signal, and when the button is mistakenly pressed, the cancel operation cannot be realized under the condition of not changing the current working state of the electric appliance. Meanwhile, the existing self-generating device is generally provided with two buttons to control the on and off of the appliance, respectively. When a user finds a button selection error, they often quickly toggle the switch to effect a change in the appliance state. For example, when the self-generating device is used to control the turning-on and turning-off of the electric lamp, when the user presses the first driving body, the control signal is instantly generated and the electric lamp is instantly turned on. If the user finds that it is not actually necessary to turn on the lamp, i.e., it is turned on by mistake, the user immediately presses the second driving body, so that the lamp is immediately turned off. Since the turn-on and turn-off intervals of the lamp are short in the above process, the lamp is easily damaged. In the case where the first driving body 2e and the second driving body 2f are in their initial positions, the second engaging rack 2c and the first engaging gear 2a and the third engaging rack 2d and the second engaging gear 2b are in an unengaged state, and the process of pressing down the first driving body 2e or the second driving body 2f includes three stages, the first stage is to move down by a first set distance so that the second engaging rack 2c and the first engaging gear 2a are switched from a disengaged state to an engaged state, or so that the third engaging rack 2d and the second engaging gear 2b are switched from a disengaged state to an engaged state. The second stage is to continue moving downward by a second set distance, so that the second meshing rack 2c and the first meshing gear 2a are switched from the meshing state to the state to be separated, or the third meshing rack 2d and the second meshing gear 2b are switched from the meshing state to the state to be separated. The third stage is to continue moving downward by a third set distance so that the second engaging rack 2c is completely separated from the first engaging gear 2a, or so that the third engaging rack 2d is completely separated from the second engaging gear 2 b. In the first phase, the first meshing rack 15 does not move and therefore does not trigger the generation of electrical energy. First meshing rack in the second phase, the moving speed of the first driving body 2e or the second driving body 2f is directly related to the pressing speed of the user, so that the first meshing rack 15 moves at an unstable and small speed, and then unstable electric energy is generated to trigger the sending of the control signal. In the third phase, the first meshing rack 15 can obtain enough energy based on the first energy storage part 16 and the second energy storage part 17 to obtain enough moving speed, and then can generate enough electric energy to trigger the sending of the control signal. Thus, the first phase can provide the user with sufficient thinking time so that the user can perform the undo operation without affecting the current working state of the appliance 4. The two, current from power generation facility, when pressing the button, just can promote the generator motor through the button and generate electricity, the generating efficiency of generator motor can receive the speed influence that pushes down of button. According to the invention, the first energy storage part 16 and the second energy storage part 17 are arranged, so that the moving speed of the first meshing rack 15 is not influenced by the pressing speed of the first driving body 2e or the second driving body 2f, and the stability of the power generation process in each power generation period is higher. The third, based on the elastic potential energy that first power transmission subassembly 1b and second power transmission subassembly 1c stored respectively for first meshing rack 15 can make a plurality of times of round trip movement between primary importance and third position, and at this in-process, can continuously produce the electric energy from power generation module 1, and then make signal forwarding module 3 continuously work, make the duration of the control command that it sent increase.
