Moreover, for the remote controller, comfortable hand feeling and sensitive control are very important, and the existing passive wireless switch technology cannot be applied to actual products because the technology is used for manufacturing the multi-key remote controller of the electric appliance and has the defects of large stroke, poor hand feeling and large noise. On the other hand, the existing self-generating device has low generating efficiency and is not suitable for providing enough electric energy for signal transmitting operation of various key instructions of the remote controller.

Fig. 1A to 15 show a preferred embodiment of a self-generating remote controller according to the present invention. Specifically, the self-generating remote controller includes a housing 10, a key device 20, a controller 30, and a kinetic energy generating device 40. The housing 10 includes a key cover 11 and a drive cover 12. The key cover 11 and the driving cover 12 may be disposed on opposite sides of the housing 10, as an upper cover and a lower cover of the housing 10, respectively; or the driving cover 12 is located at the side of the cloth key cover 11, such as the cloth key cover 11 is located at the upper side of the housing 10, and the driving cover 12 is located at a certain periphery of the housing 10.

In this embodiment of the present invention, the driving cover 12 may be a lower cover of the self-generating remote controller, and the key cover 11 may be an upper cover to form a containing cavity 13, the key device 20 includes one or more keys 21, which can cooperate with the controller 30 to complete command information acquisition, and the kinetic energy generating device 40 can generate at least one induced current under the driving action of the driving cover 12 to supply to the controller 30, so that the controller 30 can emit at least one remote control signal under the supply of electric energy. In this embodiment, the controller 30 and the kinetic energy generating device 40 are disposed in the accommodating chamber 13.

More specifically, the controller 30 is a circuit board device integrating a plurality of circuit modules, and includes one or more key electrodes 31, a coding module 32, a wireless signal transmission source 33, and a shaping circuit 34. The induced current generated by the kinetic energy generating device 40 is supplied to the encoding module 32 to transmit an ammonium key instruction corresponding to a certain key electrode 31 to an electrical appliance needing remote control through the wireless signal emission source 33 after passing through the shaping circuit 34.

The key device 20 may comprise a plurality of keys 21 which are independent of each other, or in this embodiment of the invention, the key device 20 further comprises a keypad board 22 which is integrally formed with the plurality of keys 21, so that the key device 20 of the invention may form an integrated key pad. Each of the keys 21 includes a pressing portion and a conductive portion disposed on the pressing portion, such as being embedded in the pressing portion or coated on the surface of the pressing portion. The pressing part can be made of flexible materials, such as silica gel materials, so that the comfort degree of pressing of an operator is guaranteed. The conductive portions are used to conduct the corresponding electric board 31 of the controller 30, and thus may be a suitable conductive material such as a conductive rubber material. The key arrangement cover 11 has a plurality of key grooves 111 on the top surface thereof to match the pressing portions of the keys 21.

The key device 20 is attached to the key distribution cover 11, the pressing portion of each key 21 protrudes from the corresponding key slot 11, so that an operator can conveniently perform pressing operation, or a plurality of keys 21 protrude from the same key slot 11, or each key 21 may not protrude from the key slot 11, such as being substantially flush with the surface of the key distribution cover 11 and embedded in the key distribution cover 11. The contact point of the conductive part of each key 21 is arranged on the back surface of the pressing part and is matched and opposite to the corresponding key electrode 31 on the controller 30, so that the conductive part is conductive. That is, when the operator presses the pressing portion of each key 21, the conductive portion is in contact with and conducted with the key corresponding key electrode 31 of the controller 30, and when the operator releases the silicone portion 211, the pressed key 21 returns to the original position, that is, when the key is not pressed initially, the conductive portion is not in contact with the corresponding key electrode 31. When the key 21 is pressed, the conductive part of the key 21 is in contact with the corresponding key electrode 31 on the controller 30 for conduction, the coding module 32 sends out a control instruction corresponding to the key 21, and the wireless signal emission source 33 receives the corresponding control instruction sent out by the coding module 32 and sends out a remote control signal to control a remote electric appliance. It should be understood that the structure of the key device 20 is only for example and not for limiting the present invention, and it only needs to be configured to be pressed to cooperate with the controller 30 to complete the function of collecting the command information.

That is, the wireless signal transmitting source 33 is only required to realize the function of transmitting the wireless remote control signal, and the present invention is not limited in this respect.

It is worth mentioning that in this embodiment of the present invention, the infrared emission is taken as an example. The structure of the remote controller of the invention can adapt to the multi-key arrangement of the infrared remote controller, for example, when the remote controller of the invention is applied to the control of a television, the keys 21 are correspondingly connected with circuits for completing control instructions such as a power switch, channel increase and decrease selection, volume increase and decrease selection, digital input, display menus and the like. When the remote controller of the present invention is applied to control of an air conditioner, for example, the keys 21 are correspondingly turned on to complete circuits for controlling commands such as power switch, mode selection, air volume selection, temperature selection, and the like. When the remote controller is applied to the control of an intelligent electrical system such as an intelligent home system, the keys 21 of the remote controller can be correspondingly connected with circuits for completing the power connection and control of different electrical appliances such as televisions, air conditioners, sound equipment, intelligent curtains, illuminating lamps and other household electrical appliances.

The housing 10 is further provided with a window 14, and for example, one side of the key cover 11, for example, the right side in fig. 1, is further provided with the window 14 corresponding to the wireless signal emission source 33 implemented as an infrared emission diode, and the infrared emission diode is positioned corresponding to the window 14 for emitting an infrared remote control signal to a remote appliance.

In this embodiment of the present invention, the arrangement of the cloth key cover 11 for the keys 21 is such that the pressing portion of each key 21 protrudes from the top surface of the cloth key cover 11 for the operator to press the key 21 conveniently. The driving cover 12 is used for starting the kinetic energy generating device 40, that is, the driving cover 12 can drive the kinetic energy generating device 40 to convert mechanical energy into electric energy when being pressed to provide electric energy for the controller 30. Therefore, in the embodiment of the invention, the collection of the key instruction information and the generation of the electric energy are independently carried out, so that the arrangement of a plurality of keys of the remote controller can be facilitated. In other words, in the prior art, the power generation device needs to be driven to generate power while the key is pressed, so that the arrangement of multiple keys is not easy to realize, and thus, the remote controller can only be implemented as a passive wireless switch with simple switch keys to play a role in turning on and off an electric appliance, but cannot be like the remote controller of the present invention, and not only can realize a switch function, but also can realize the above-mentioned various remote control functions.

Fig. 3 to 12 show an embodiment of the kinetic energy generating device 40, which discloses one of the structures of the kinetic energy generating device 40, which can convert mechanical energy into electrical energy when being driven to provide the electrical energy to the controller 30. For example, a piezoelectric effect generator, an electromagnetic induction generator, or the like. In this embodiment, the kinetic energy generating device 40 includes, by way of example, a magnet assembly 42, a coil 43, and a center post 44. The magnetic assembly 42 includes a permanent magnet 421 and two

magnetizers

422 and 423 located at two opposite sides of the permanent magnet 421 to form opposite magnetic poles, i.e. a top magnetizer 422 and a bottom magnetizer 423, and a magnetic gap 424 is formed between the two magnetizers, and one end of the center pillar 44 extends into the magnetic gap 424. The coil 43 is disposed around the center pillar 44, and the coil 43 is electrically connected to the controller 30, wherein the center pillar 44, which may be implemented as a magnetic conductor such as an iron core, can alternately contact the two

magnetic conductors

422 and 423, so that the direction of the magnetic induction line passing through the coil 43 is changed, so as to generate an induced current in the coil 43, so that the kinetic energy generating device 40 can provide electric energy for the controller 30 and supply the electric energy to the encoding module 32 and the wireless signal transmitting source 33 for signal transmission operation under the power shaping effect of the shaping circuit 34 of the controller 30.

It will be appreciated that the magnet assembly 42 is fixed and the central leg 44 can be driven to alternately contact the two

conductors

422 and 423. Or the center pillar 44 is fixed, the magnetic assembly 42 is driven to move to make the two

magnetizers

422 and 423 contact with the center pillar 44, respectively, so that the induced current is generated in the coil 43 disposed around the center pillar 44. The coil 43 may be directly sleeved on the center pillar 44, or the coil 43 may be sleeved on a coil frame, and the coil frame is further sleeved on the center pillar 44.

In the preferred embodiment of the present invention, the kinetic energy generating device further comprises a magnetic conductive cavity 41. The coil 43 is disposed in a magnetic conducting cavity 410 formed by the magnetic conducting cavity 41, and the magnetic group 42 performs reciprocating displacement on one side surface of the magnetic conducting cavity 41, so as to convert mechanical kinetic energy into electric energy. More specifically, the magnetic cavity 41 may be implemented as a magnetic shell, the center pillar 44 is located in the magnetic shell, the center pillar 12 and the magnetic shell comprise magnetic materials and are assembled or integrally formed to improve magnetic efficiency, and the coil 43 is disposed inside the magnetic shell, i.e., in the magnetic cavity 410, and surrounds the center pillar 44. Except one side of the magnetic conductive shell is provided with an opening 411, other sides such as other four sides or five sides can be shielded by magnetic conductive materials. That is, the magnetically conductive chamber 41 forms a relatively closed magnetically conductive container in which the coil 43 is accommodated, and the opening 411 is implemented as a magnetic group seal. Thus, when the magnet assembly 20 is used to seal the opening 411, the coil 30 is completely covered by the magnetic induction lines, thereby reducing the leakage flux of the entire magnetic circuit system. In other words, in this embodiment, the magnetic conductive cavity 41 forms a relatively closed magnetic conductive cavity, so as to reduce magnetic leakage.

The magnetic group 42 includes the permanent magnet 421, the top magnetizer 422, and the bottom magnetizer 423, and the permanent magnet 421 is disposed between the top magnetizer 422 and the bottom magnetizer 423. The top magnetizer 422 and the bottom magnetizer 423 each have one end placed inside the magnetic conductive chamber 410, and the top magnetizer 422 and the bottom magnetizer 423 each have a portion protruding with respect to the permanent magnet 421, and the magnetic gap 424 is formed between the protruding portions, and the outer end of the center pillar 44 extends into the magnetic gap 424. The width between the top magnetizer 422 and the bottom magnetizer 423 is the width of the magnetic gap. It is understood that the top magnetizer 422 and the bottom magnetizer 423 are made of magnetic conductive materials or coated with magnetic conductive materials. The permanent magnet 421 is made of a permanent magnetic material, such as a magnet, an alnico permanent magnetic alloy, an iron-chromium-cobalt permanent magnetic alloy, a permanent magnetic ferrite, a rare earth permanent magnetic material, a composite permanent magnetic material, and the like. It is worth mentioning that, in the operation of the kinetic energy generating device 40 to generate electric energy, when the middle pillar alternately contacts the top magnetizer 422 and the bottom magnetizer 423, the top magnetizer 422 and the bottom magnetizer 423 may also alternately collide with the top edge and the bottom edge of the magnetic conductive shell 411, respectively, so that the direction of the magnetic induction line passing through the coil 43 is changed, thereby generating an induced current in the coil 43. It is of course understood that in other embodiments, the top magnetic conductor 422 and the bottom magnetic conductor 423 may also each have no end disposed inside the magnetic conductive cavity 410, i.e., do not extend into the interior of the magnetic conductive cavity 410.

It is to be understood that the kinetic energy generating apparatus of the present invention may be various apparatuses capable of converting mechanical energy into kinetic energy. In the illustrated preferred embodiment of the present invention, the coil 43 is disposed inside the magnetic conduction cavity 411, the magnetic group 42 is enclosed on the side, and the coil 43 is covered by the magnetic induction lines, so that the leakage flux is minimized, and thus the generated energy is much higher than that of the conventional kinetic energy power generation device, so that the kinetic energy power generation device of the present embodiment has a higher power generation efficiency.

More specifically, the magnetic cavity 41 may include a top case 412, two side wings 413, and a bottom case 414, which may be assembled or integrally formed. The two side wings 413 respectively extend to two sides of the top case 412, the bottom case 414 extends to connect the two side wings 413, one end of the bottom case 414 of the magnetic conductive cavity 41 extends outward to form a bottom edge 4141, and the other end extends upward and outward to form the center pillar 44, that is, the center pillar 44 extends to one end of the bottom case 414 and is parallel to and opposite to the bottom case 414, and a gap is left between the center pillar 44 and the two side wings 413 of the magnetic conductive cavity 41, so that the coil 43 is sleeved on the center pillar 44. It is understood that the center pillar 44 may be assembled to the magnetic conductive cavity 41, or may be integrally formed in the magnetic conductive cavity 41 in other manners, and the invention is not limited in this respect.

In this embodiment of the present invention, the magnetic cavity 41 can be fixed and the magnetic group 42 is driven to make the center pillar 44 in the magnetic cavity 41 and the magnetic group 42 generate relative displacement. The magnetic conductive cavity 41 may be fixedly connected to the controller 30, or fixedly connected to the casing 10, such as fixed to the key cover 11.

One end of the top magnetizer 422 extends outward to form a top magnetizer abutting end 4221, one end of the bottom magnetizer 423 extends outward to form a bottom magnetizer abutting end 4231, and the top magnetizer abutting end 4221 and the bottom magnetizer abutting end 4231 can be arranged inside the magnetism guiding cavity 410. The width between the top magnetizer abutting end 4221 and the bottom magnetizer abutting end 4231 is the width of a magnetic gap. Under the action of external force, the top magnetizer abutting end 4221 and the bottom magnetizer abutting end 4231 alternately contact with the top edge 4121 and the bottom edge 4141 of the magnetic cavity 41, respectively, and the center pillar 44 alternately contacts with the bottom magnetizer abutting end 4231 and the top magnetizer abutting end 4221, so that the direction of the magnetic induction line passing through the coil 43 is changed, thereby generating an induced current in the coil 43.

It can be understood that the magnetic conductive cavity 41 and the magnetic group 42 generate relative displacement, so that the kinetic energy generating device 40 generates the induced current. It is contemplated by those skilled in the art that the magnetic cavity 41 may be fixed and the magnetic assembly 42 driven to displace relative to each other, or the magnetic assembly 42 may be fixed and the magnetic cavity 41 driven to drive the center post 44 to displace relative to each other, such that the center post 44 alternately contacts the bottom and top magnetizer abutment ends 4231 and 4221, thereby causing the coil 43 to generate the induced current.

Further, in order to make the kinetic energy power generation device 40 more easily realize the displacement of the magnetic group 42 relative to the magnetic conduction cavity 41 by applying an external force, the kinetic energy power generation device 40 further includes a driving bracket 45, and the magnetic group 42 is disposed in the driving bracket 45. In the example shown in the figure, the magnet pack 42 can oscillate up and down, with a stroke determined by the width of the magnetic gap (for example, 0.5mm can be implemented, but the invention is not limited thereto). That is, the driving bracket 45 fixes the magnet assembly 42 such that the magnet assembly 42 alternately abuts against the top edge 4121, the center pillar 44, and the bottom edge 4141 in the magnetic gap range. In addition, the driving bracket 45 is also used for supporting and stabilizing the magnetic group 42. The driving bracket 45 is pivotally engaged with the magnetic cavity 41, so that the driving bracket 45 can be driven to displace the magnetic assembly 42 relative to the center pillar 44 in the magnetic cavity 41. Of course, in other embodiments, the driving bracket 45 may be fixed, and the magnetic conductive cavity 41 may be driven to displace.

More specifically, the kinetic energy generating device 40 further includes a driving member 46 connected to the driving bracket 45, and the driving bracket 45 can be driven when an external force is applied to the driving member 46. The drive bracket 45 includes a bracket base 451, a magnet unit fixing arm 452, and a swing arm 453. The driving element 46 is connected to the bracket base 451 of the driving bracket 45, and preferably, the driving element 46 can be integrally injection-molded with the driving bracket 45. In particular, the drive element 46 may be embodied as a spring plate in this embodiment, the elastic structure being capable of rapidly displacing the drive carrier. That is, the elastic piece is connected to the holder base 451 in this embodiment. The elastic sheet 41 is also used to increase potential energy, and accelerate the movement speed of the magnetic assembly 42 of the kinetic energy power generation device 40.

The magnetic group fixing arm groups 452 extend inward from both ends of the U-shaped holder base 451 and form a magnetic group fixing groove 454 with the holder base 451. The top magnetizer 422, the bottom magnetizer 423 and the permanent magnet 421 of the magnet assembly 42 are assembled and then disposed in the magnet assembly fixing groove 454, and the magnet assembly fixing groove 454 has an opening 455 facing the center pillar 44 in the magnetic conductive cavity 41, so that the center pillar 44 extends into the magnetic gap 44 of the magnet assembly 42. It should be noted that each of the magnetic group fixing arm groups 452 is further convexly provided with a abutting end positioning pin 4521 for respectively stabilizing the top magnetic abutting end 4221 of the top magnetizer 422 and the bottom magnetic abutting end 4231 of the bottom magnetizer 423, so that the magnetic group 42 can be more stably disposed in the magnetic group fixing groove 454. It is understood that the driving bracket 45 may have other structures capable of forming a fixing groove to fix the magnet assembly 42.

The swinging arm sets 453 further extend outward from the respective bracket bases 451 and each have a rotating shaft 4531 at the inner side of the distal end, and accordingly, the two side wings 413 of the magnetic conductive cavity 41 are each provided with a rotating shaft groove 4131. Each of the rotating shafts 4531 is positioned in each of the corresponding rotating shaft grooves 4131, so that the driving bracket 45 swings around the rotating shaft 4531, and the driving bracket 45 drives the magnetic group 42 to alternately abut against the top edge 4121, the bottom edge 4141 and the center pillar 44 of the magnetic conductive cavity 41. It is understood that the rotating shaft 4531 and the rotating shaft groove 4131 may be respectively disposed on the lateral wing 413 of the magnetic conductive cavity 41 and the swing arm assembly 453 of the driving bracket 45. It will be understood by those skilled in the art that the above-mentioned structure of the driving bracket 45 and the magnetically conductive cavity 41 pivotally coupled in a matching manner is also only an example and is not intended to limit the present invention.

In this embodiment of the present invention, the coil 43 is disposed in the magnetic conducting cavity 410 of the magnetic conducting cavity 41 and is sleeved on the middle pillar 512, the driving bracket 45 disposes the magnetic group 42 in the magnetic group fixing groove 454, and the driving element 46 is connected to the driving bracket 45, so that the swing of the driving element can make the magnetic group 42 perform a swing displacement change, thereby generating an induced current in the coil 43, and further the kinetic energy generating device 40 provides a power source for the self-generating remote controller.

The kinetic energy generating device 40 further includes a reset element 47, the reset element 47 accumulates potential energy when the driving element 46 drives the driving bracket 45 and drives the magnet assembly 42 to displace, and when the external force applied to the driving element 46 disappears or decreases to a predetermined magnitude, the reset element 47 can return the driving element 46 to the initial position, so that the magnet assembly 42 returns to the initial position, and the center pillar 44 again alternately contacts the top magnetizer 422 and the bottom magnetizer 423, so that another induced current can be generated again. I.e., one cycle operation, in this embodiment of the invention, two induced currents may be generated.

In this embodiment, the self-generating device 40 is located between the driving cover 12 and the controller 30, and the reset element 47 is connected to the driving element 46 at one end and fixed to the controller 30 at the other end, or fixed to the housing 10 at the other end, such as to the inner surface of the key cover 11. The reset element 47 can be implemented as various elements capable of accumulating potential energy when being stressed and automatically resetting when the stress is relieved or reduced, such as a spring plate, a compression spring, a torsion spring, and the like.

The top side of the magnetic conductive cavity 41 may further include two pins 415, and two ends of the coil 43 may be respectively located at the pins 415, and further connected to the shaping circuit 34 of the controller 30, so that the electric energy generated by the kinetic energy generating device 40 is supplied to the controller 30.

In this embodiment of the invention, the drive cap 12 is multi-directional and can oscillate slightly up and down, left and right, and back and forth, with a stroke of about 1.5mm or less. Specifically, the driving cover 12 includes a driving cover main body 121, and an actuating element 122 convexly disposed on an inner surface of the driving cover main body 121 for pressing the driving element 46 to drive the magnetic assembly 42, and the driving cover 12 further includes a plurality of hooks 123, such as four hooks 123 on four sides, slidably engaged with the key distribution cover 11 for fixing and limiting. If a corresponding number of sliding grooves 112 are formed inside the key cover 11, the hooks 123 are slidably disposed on the sliding grooves 112. It is understood that the hook 123 may be disposed on the key cover 11, and the sliding groove 112 may be disposed on the driving cover 12. The slide groove 112 may also be provided on the outer surface of the key top 11, i.e., the drive cover 12 may be located on the outer side of the key top 11, unlike the drive cover 12 shown in fig. 11 and 12 which is located on the inner side of the key top 11, so that the drive cover 12 moves on the outer side of the key top 11.

It should be noted that, as shown in fig. 11, the top of the reset element 47 abuts against the driving element 46 to make the magnetic assembly 42 in the initialization position shown in fig. 10A, and the reset element 47 simultaneously makes the four hooks 123 of the driving cover 12 hook the four sliding slots 112 of the cloth key cover 10 to make the driving cover 12 in the initialization state. That is, the sliding groove 112 limits the hook 123 accordingly, so that the driving cover 12 does not fall off from the cloth key cover 10, and can flexibly generate relative displacement.

The driving element 46 (which may be implemented as a spring plate) that is a starting part of the power generation operation of the self-generating remote controller is pushed by the driving cover (which may be implemented as a lower cover) disposed at the bottom surface of the self-generating remote controller. In the passive wireless switch in the prior art, the keys are required to press and move and also need to be abutted against the conductive rubber, the action is complex, and more keys cannot be arranged. The self-generating remote controller of the invention separates two parts, namely the moving part, namely the driving cover 12, and the key information acquisition part, namely the key device 20, have separated functions, do not interfere with each other, work independently and operate continuously at the same time. It should be noted that the driving cover 12 can also be a part of the lower cover, such as only the size of the corresponding key area.

Fig. 10A and 10B are schematic diagrams illustrating the power generation principle of the kinetic energy power generation device 40. Wherein the dotted lines with arrows in the figure indicate the direction of the magnetic induction lines. As shown in fig. 10A, in an initial state, the top magnetizer abutting end 4221 of the top magnetizer 422 connected to the N pole of the permanent magnet 421 abuts against the center pillar 44, and the bottom magnetizer abutting end 4231 of the bottom magnetizer 423 connected to the S pole of the permanent magnet 421 abuts against the bottom edge 4141. At this time, the magnetic induction line is in a steady state, and no induced current is generated in the coil 43. As shown in fig. 10B, if the driving element 45 is driven by the driving cover 12 to move the magnet assembly 42 upward, the top magnetizer abutting end 4221 abuts against the top rim 4121. And the bottom magnetizer abutting end 4231 connected with the S pole of the permanent magnet 421 abuts against the center pillar 44. It will be appreciated by those skilled in the art that the above-described azimuthal arrangements of the N and S poles are also exemplary only and not limiting to the invention. During the moving process, the direction of the magnetic induction line passing through the coil 43 is changed, and the coil 43 generates an induced current due to the rapid change, and the magnitude of the current is directly related to the displacement speed of the magnetic group 42, the number of turns of the coil 43, the magnetic permeability of the magnetic conductive material, the magnetic leakage rate, the magnetic saturation strength and other parameters.

The calculation formula of the induced electromotive force is as follows:

E＝-n*ΔΦ/Δt

in the formula: e is induced electromotive force, n is the number of turns of the coil, and Δ Φ/Δ t is the rate of change of magnetic flux.

Further, the kinetic energy generating device 40 provides a power source for the self-generating remote controller. In addition, when the external force applied to the driving cover 12 disappears or decreases to a predetermined magnitude, the magnetic group 42 returns from the position of fig. 10B to the position of fig. 10A by the reset action of the reset element 47, so that the direction of the magnetic induction line passing through the coil 43 is changed again, and this rapid change causes the coil 43 to generate a current to be induced again.

As shown in fig. 12, a process of operating the self-generating remote controller by an operator is disclosed:

when the key 21 is pressed, the conductive portion (which is implemented as conductive rubber) conducts the corresponding key electrode 31 of the controller 30, and the pressing force F required for the key 21 is about F1 — 0.2N in value.

The trigger element 122 of the drive cap 12 is supported by the reset element 47 and requires a force F2-2-3N when pressed, wherein F1 < F2.

When the operator starts to use the remote controller, the thumb of the operator presses the key 21 in fig. 12 due to the action of the hand, and the other four directions push the driving cover 12 in the palm center; of course, other ways may be used according to the habit of the operator, such as pressing the key 21 with the index finger and pressing the driving cap 12 with other fingers.

When f is larger than 0.2N, the stroke of the key 21 reaches the end point, the key electrode 31 on the controller 30 is conducted in advance, but at the moment, the controller 30 is not powered yet, and the key electrode 31 is conducted in advance to prepare a corresponding instruction for transmission immediately after power is on; each of the keys 21 has a different command, which is generated by an encoder in the encoding module 32.

When the force applied to trigger 122 of the driving cap 12 is greater than 3N, the distal-most end of the driving cap 12 may be depressed by about 1.5mm (1.5 mm is taken as an example of this embodiment of the present invention, but not limited thereto), and the trigger 122 may be pressed against the driving element 46 by a stroke of 0.75 mm.

The driving element 46 moves the magnet assembly 42, and the displacement of the magnet assembly 42 causes the center post 44 to alternately contact the top magnetizer 422 and the bottom magnetizer 423 of the magnet assembly 42, thereby generating an induced current in the coil 43.

The current generated by the coil 43 can provide the encoding circuit with dc power having a voltage of about 2V and a duration of about 10ms after passing through the shaping circuit 34 of the controller 30.

At this time, the circuit part obtains electric energy and starts to work, and the encoder of the encoding module 32 transmits a remote control signal according to the instruction of the corresponding key electrode 31 at the key 21 pressed in advance.

Within 10ms, the wireless signal transmission is completed, at this time, the inward movement stroke of the driving cover 12 is in place, the grip force of the operator is still maintained, so that the state of the magnetic group 42 is kept still, the previously generated induced electric energy is also consumed, and the circuit is in a power-off state again.

At this time, if the hand holding the self-generating remote controller is released, the driving cover 12 starts to be reset towards the outside of the self-generating remote controller under the pushing force of the reset element 47, and the touch element 122 retreats along with the driving cover 12.

The reset element 47 pushes the driving element 45 and the touching element 122 to reset towards the outside of the self-generating remote controller, causing the magnetic assembly 42 to return to the original initial position (fig. 10A), and thus, an induced current is generated in the coil 43 again.

The re-generated induced current will in turn power up the circuit for 10ms and issue a corresponding signal (e.g. a release signal) command.

The signal can be transmitted twice in total by pressing a key once. The remote controlled appliance may be designed to perform a corresponding control operation only by receiving a first signal, or to perform a corresponding control operation only by receiving a second signal, or to perform a corresponding control operation by receiving both signals.

It should be noted that F1 and F2 are defined as characteristic values, F1 is the minimum force value required for the conductive rubber to conduct the controller key electrode, F2 is the minimum force value required for the triggering element 122 to press the driving element 46 to make the magnetic group 42 abut against the center pillar 44 in the magnetic conducting cavity 41, and F2> F1. Therefore, in the releasing step, when F is reduced to be below F2 but is larger than F1 in the releasing process due to the characteristic values F2> F1, the driving cover 12 is retracted but the key is not released, and the corresponding key electrode can still be in the pre-connection state. In addition, it should be noted that the values of the specific parameters appearing in the above operation process are only used as examples and do not limit the present invention, and can be designed according to the actual application.

In addition, the key operation for the key 21 of the key device 20 and the pressing operation for the driving cover 12 are independent two operations, which can be performed simultaneously; the key operation for the key 21 of the key device 20 may be performed before and then the pressing operation for the drive cover 12 may be performed; alternatively, before the pressing operation of the driving cover 12, the key operation of the key 21 of the key device 20 is performed, and then the driving cover 12 is released, and when the driving cover 12 is released, a second induced current may be generated, thereby transmitting a wireless control signal.

In this preferred embodiment of the present invention, any position of the outer surface of the driving cover 12 can be pressed, and as long as the hand presses any position of the outer surface of the driving cover 12, the touching element 122 can be made to collide with the driving element 46 to displace, and the displacement of the driving element 46 will drive the magnetic group 42 to displace, so that the polarity of the magnetic induction line passing through the coil 43 changes, thereby generating an induced current in the coil 43.

It is worth mentioning that, as shown in fig. 13, transmitting the signal twice can realize important functions, such as stepless volume adjustment, brightness adjustment, and other continuous variables.

More specifically, for general control requirements, one firing is enough, and one firing is unnecessary at all, and the firing is not necessary again when the spring reset is carried out. However, in the daily remote control operation of the electrical appliance, there are cases, such as the adjustment of the volume of the television, the adjustment of the brightness, and other items, if the traditional remote controller using the battery is used, the remote controller continuously transmits the instruction as long as the button is pressed and the hand is not loose, and the volume is gradually changed, which is a continuous variable quantity; the remote controller from electricity generation can only have the electric energy in the twinkling of an eye of pressing, presses and send a signal once, if press key volume change a bit once, if the scope of adjustment is more, the button that does not stop, the hand can be tired relatively. Therefore, continuous key emission of the traditional remote controller is simulated through the time difference of the two times of emission so as to realize stepless adjustment of volume and brightness.

That is, it is worth mentioning that variable operations requiring continuous adjustment, such as stepless adjustment of volume and brightness, can be realized by using the time difference between two transmissions as shown in fig. 13.

Further, in a general key operation, the time for pressing and releasing the key does not exceed 1s, and like a television remote controller, the key is usually pressed and released in a channel selection operation, the process is usually 0.2-0.5s, if the time for pressing the key exceeds 1s and the hands are not loose, the MCU at the receiving end considers that the user is performing a continuous operation, and then a program for adjusting continuous variables is executed, such as: when the adjustment volume is increased, if the time for pressing the volume key exceeds 1s, at this time, the receiving end receives the instruction when pressing, and still does not receive the instruction for releasing after waiting for one second, so that the MCU (Microcontroller Unit) can continuously increase the volume until receiving the position of the key for releasing the instruction, thereby realizing the adjustment control of continuous variables under the passive wireless technology. The logic diagram is shown in fig. 14B.

Fig. 15 is a block diagram of the wireless transmission circuit system. When the key 21 is pressed, the key 21 is contacted with the corresponding key electrode 31, the current generated by the coil 43 of the kinetic energy generating device 40 can provide direct current power for the encoding circuit after passing through the power shaping circuit, so that the circuit part of the controller 30 obtains the power, and the encoding module 32 sends out a wireless control instruction corresponding to the key 21 and transmits a corresponding remote control signal such as an infrared wireless signal through the wireless signal transmitting source 33 to control a remote electrical appliance.

Therefore, taking infrared signal transmission as an example, the infrared wireless signal transmission process of the self-generating remote controller of the invention is as follows: at least one key 21 of the self-generating remote controller is pressed, and a conductive part of the key 21 is conducted with a key electrode 31 corresponding to a controller; a convex point (the touch element 122) of a driving cover 12 of the self-generating remote controller is pressed; the return spring (the return element 47) supporting the salient point drives a spring plate (the driving element 46), the spring plate drives the magnetic assembly 42 of the kinetic energy generating device to move, and the displacement of the magnetic assembly 42 causes the induced current to be generated in the coil 43; the current generated by the coil 43 provides direct current power for the encoding module 32 after passing through the shaping circuit 34 of the controller; the encoder of the encoding module 32 will issue a corresponding instruction according to the corresponding key electrode that is turned on; an infrared emitting diode (the wireless signal emitting source 33) receives the instruction and emits a remote control signal of infrared light waves; the state of the magnetic group 42 is kept temporarily static, and the circuit is in a power-off state again after the previously generated induced electric energy is consumed; when the driving cover 12 is loosened, the return spring pushes the elastic sheet and the salient points to return; the magnetic group 42 is driven by the elastic sheet to generate relative displacement, and induced current is generated in the coil 43 again; the current generated by the coil 43 is supplied to the controller; the encoding module of the controller re-emits the remote control signal of the infrared light wave through the infrared emitting diode.

In addition, the continuous variable signal control method of the present invention has a remote controller portion, that is, the self-generating remote controller of the present invention and a receiving processor portion of a remote-controlled appliance, and the continuous variable signal control process is as follows: at least one key 21 of the remote controller is pressed; the coding module 32 of the controller 30 of the remote controller is in a switch-on state corresponding to the circuit of the key instruction of the key 21; the driving cover 12 of the remote controller is pressed and triggers the kinetic energy generating device 40 to generate electric energy; the controller 30 of the remote controller encodes and transmits infrared signals according to corresponding key instructions under power supply; the receive processor portion receives a decode; the receiving processor part judges whether two instructions are received or not within the set time, and if the two instructions are received, the receiving processor part performs continuous key processing, so that the control of continuous variable signals is realized. It is understood that the receiving processor portion may determine to perform a single key pressing process according to the fact that no instruction is received twice within the above-mentioned set time.

It should be noted that, in the preferred embodiment of the present invention, for convenience of description, the signal emission source in the self-generating remote controller is described by using an infrared emission manner as an example, but those skilled in the art can understand that the signal emission source in the present invention is not limited to the infrared emission manner, and may also be other reasonable implementations such as bluetooth and WIFI, and the present invention is not limited thereto.

Correspondingly, the invention provides a wireless signal transmitting method of a self-generating remote controller, which comprises the following steps: in response to a key operation and an independent power generation pressing operation, the self-generating remote controller generates power and emits a wireless control signal corresponding to the key operation.

More specifically, for example, in the present invention, the wireless signal transmission method further includes the steps of:

in the key operation: when at least one key 21 of the key device 20 is pressed, the control command circuit of the controller 30 corresponding to the key 21 is turned on;

in the power generation pressing operation: when the driving cover 12 is pressed, the kinetic energy generating device 40 is driven to convert mechanical energy into electrical energy; and

the controller 30 transmits a wireless control signal corresponding to the key 21 under the power supply provided by the kinetic energy power generation device.

It is understood that the key operation refers to various operations for completing key instruction information collection through keys. The power generation pressing operation may be any operation capable of implementing driving of the kinetic energy power generation device 40 to cause the kinetic energy power generation device 40 to perform a self-power generation function, independently of the key operation, and is not limited to the illustrated embodiment of the present invention.

Accordingly, in the key operation, the pressed key 21 connects the corresponding key electrode 31 of the controller 30 into a circuit, and the encoding module 32 of the controller 30 is preset with an encoding instruction corresponding to the key electrode 31.

In the power generation pressing operation, the center pillar 44 of the kinetic energy power generation device 40 is caused to alternately contact the top magnetizer 422 and the bottom magnetizer 423 of the magnet group 42 by the driving action of the driving cover 12, and the coil 42 disposed around the center pillar 44 generates a primary induced current. Accordingly, when the driving cover 12 is pressed, the magnetic assembly 42 is driven to move, and the center pillar 44 is also driven to move.

More specifically, in this particular example of the invention, the actuating element 122 of the driving cover 12 presses against the driving element 46, the driving element 46 drives the driving bracket 45 to move, and the magnetic group 42 moves accordingly, so that the central pillar 44 alternately contacts the bottom magnetizer 423 and the top magnetizer 422 of the magnetic group 42.

In addition, when the actuating element 122 of the driving cover 12 presses against the driving element 46, the reset element 47 is elastically deformed, and in the subsequent process of releasing the pressed driving cover 12, that is, when the pressing force is reduced, the reset element 47 is restored from the elastically deformed state to the initial state, so that the center pillar 44 alternately contacts the top magnetizer 422 and the bottom magnetizer 423 of the magnetic group 42 again, thereby generating a second induced current.

In the wireless signal transmitting step, the induced current generated by the kinetic energy generating device 40 is supplied to the encoding module 32 after the power shaping action of the shaping circuit 34 of the controller 30, and the wireless signal transmitting source 33 connected to the encoding module 32 transmits the wireless control signal.

It is worth mentioning that when the kinetic energy power generation device 40 is in the reset step, if the pressed key 21 is still pressed, but the driving cover 12 is released, the self-generating remote controller can send out the wireless control signal twice. Therefore, the continuous variable control operation of the self-generating remote controller can be realized, or the remotely controlled electric appliance can be programmed to selectively receive any one of the wireless control signals to execute the corresponding operation. Of course, when a certain key 21 is kept pressed for a long time and the wireless control signal is sent twice, the remote controlled electric appliance may be programmed to perform certain operations correspondingly, such as pressing the key corresponding to the power switch for a long time, entering the operation of setting parameters, and the like. When the pressed key 21 is completely released in the reset step of the kinetic energy power generation device 40, the self-generating remote controller may not send out the wireless control signal any more, and the remotely controlled appliance may be programmed to selectively receive the wireless control signal sent out in the first power generation operation to perform a corresponding operation.

In addition, the invention provides a self-generating method of the self-generating remote controller, which comprises the following steps:

when the driving cover 12 is pressed, the driving cover 12 causes the magnetic assembly 42 and the center post 44 located in the magnetic conductive cavity 41 to displace relative to the magnetic assembly 42, so that the center post 44 alternately contacts the top magnetizer 422 and the bottom magnetizer 423 of the magnetic assembly 42, thereby generating an induced current in the coil 43 disposed around the center post 44. In this embodiment of the present invention, the coil 43 and the center pillar 44 are located in the magnetic conductive cavity 41, and the coil 30 is completely covered by the magnetic induction lines, so as to reduce the magnetic leakage of the whole magnetic circuit system, and improve the power generation efficiency of the whole kinetic energy power generation device 40 of the self-generating remote controller.

When the driving cap 12 is no longer pressed, the reset action of the reset element 47 causes the center pillar 44 to alternately contact the bottom magnetizer 423 and the top magnetizer 422 of the magnet assembly 42, thereby generating another induced current in the coil 43 disposed around the center pillar 44.

It is understood that in the illustrated example of the present invention, the self-generating remote controller is configured with one kinetic energy generating device 40, in practical applications, a plurality of kinetic energy generating devices 40 may be configured, and each of the kinetic energy generating devices is driven by the corresponding touch element 122 to generate electric energy, and the generated electric energy can be comprehensively utilized to be supplied to the controller 30 for transmitting wireless control signals.

Fig. 16 to 18 show another modified embodiment of the self-generating remote controller according to the present invention. In this variant embodiment, the self-generating remote control can be installed on an environmental surface. For example, the remote controller can be mounted on a wall, and is widely applied to remote control operation of air conditioners, heaters, intelligent control panels and other electrical appliances.

Specifically, as shown in fig. 16, the self-generating remote controller includes a housing 10 ', a key device 20', a controller 30 ', and a kinetic energy generating device 40'. The housing 10 ' includes a key cover 11 ' and a drive cover 12 ' pivotally engaged with each other. The driving cover 12 ' serves as a bottom cover of the self-generating remote controller, and the key distribution cover 11 ' serves as a top cover to jointly form an accommodating cavity for accommodating the kinetic energy generating device 40 ', the key device 20 ' is matched with the controller 30 ' to achieve collection of control instruction information, and the controller 30 ' sends out wireless control signals under the supply of electric energy generated by the kinetic energy generating device 40 '.

More specifically, the key device 20 ' includes one or more keys 21 ', and the key cover 11 ' has a plurality of key grooves 111 ' corresponding to the respective keys 21 '. When the key device 20 ' is disposed in close contact with the key arrangement cover 11 ', each key 21 ' protrudes from the corresponding key slot 111 ', i.e. protrudes from the top surface of the key arrangement cover 11 ', so that the operator can perform key operation conveniently. Similarly, the controller 30 'further includes one or more key electrodes 31', a coding module 32 'electrically connected to the key electrodes 31', the wireless signal transmission source 33 and the shaping circuit 34.

Preferably, in this embodiment of the present invention, the self-generating remote controller is implemented as a high frequency wireless transmission circuit when mounted on a wall. In this embodiment of the invention, the silicone key 21' can similarly function to conduct an electrical circuit. That is, the key 21 ' of the key device 20 ' is disposed at a position corresponding to the corresponding key electrode 31 ' of the controller 30 ', when the top end of the key 21 ' is stressed, the bottom end of the key 21 ' contacts the key electrode 31 ', so that the key electrode 31 ' is short-circuited, and the controller 30 ' accordingly sends out a radio frequency signal, thereby controlling a remote appliance in a radio frequency manner.

Further, the kinetic energy generating device 40 'includes a magnetic group 42', a coil 43 'and a center pillar 44'. The magnetic assembly 42 'includes a permanent magnet 421' and two magnetizers 422 'and 423' forming opposite magnetic poles at opposite sides of the permanent magnet 421 ', and a magnetic gap 424' is formed between the two magnetizers, and one end of the center pillar 44 'extends into the magnetic gap 424'. The coil 43 ' is disposed around the center pillar 44 ', and the coil 43 ' is electrically connected to the controller 30 ', wherein the center pillar 44 ' can alternately contact the two magnetizers 422 ' and 423 ' to change the direction of the magnetic induction line passing through the coil 43 ' so as to generate an induced current in the coil 43 ', so that the kinetic energy generating device 40 ' can supply electric energy to the controller 30 ' and supply the electric energy to the encoding module 32 ' and the wireless signal transmitting source 33 ' for signal transmitting operation under the power shaping effect of the shaping circuit 34 ' of the controller 30 '.

In the preferred embodiment of the present invention, the kinetic energy generating device further comprises a magnetic conductive cavity 41'. The coil 43 ' is disposed in a magnetic conducting cavity 410 ' formed by the magnetic conducting cavity 41 ', and the magnetic group 42 ' performs reciprocating displacement on one side surface of the magnetic conducting cavity 41 ', so as to convert mechanical kinetic energy into electric energy. The magnetic cavity 41 'may be implemented as a magnetic shell, the central pillar 44' is located in the magnetic shell, the central pillar 12 'and the magnetic shell comprise magnetic materials and are assembled or integrally formed to improve magnetic efficiency, and the coil 43' is disposed inside the magnetic shell, i.e., in the magnetic cavity 410 ', and surrounds the central pillar 44'. The coil 30 is completely covered by the magnetic induction lines, thereby reducing the leakage flux of the whole magnetic circuit system. In other words, in this embodiment, the magnetic conductive cavity 41' forms a relatively closed magnetic conductive cavity, thereby reducing magnetic leakage.

Similarly, the magnetic cavity 41 ' can be fixed and the magnetic group 42 ' is driven to make the central pillar 44 ' and the magnetic group 42 ' in the magnetic cavity 41 ' generate relative displacement. The magnetic conductive cavity 41 'may be fixedly connected to the controller 30' or fixedly connected to the housing 10 ', such as the key cover 11'.

Similarly, one end of the top magnetizer 422 ' extends outward to form a top magnetizer abutting end 4221 ', one end of the bottom magnetizer 423 ' extends outward to form a bottom magnetizer abutting end 4231 ', and the top magnetizer abutting end 4221 ' and the bottom magnetizer abutting end 4231 ' can be disposed inside the magnetism guiding cavity 410 '. The width between the top magnetizer abutting end 4221 'and the bottom magnetizer abutting end 4231' is the width of a magnetic gap. Under the action of external force, the top magnetizer abutting end 4221 'and the bottom magnetizer abutting end 4231' are alternately contacted with the top edge and the bottom edge of the magnetic cavity 41 ', respectively, and the central column 44' is alternately contacted with the bottom magnetizer abutting end 4231 'and the top magnetizer abutting end 4221', so that the direction of the magnetic induction line passing through the coil 43 'is changed, and the induced current is generated in the coil 43'.

The kinetic energy generating device 40 'further includes a driving bracket 45', the magnetic assembly 42 'is disposed in the driving bracket 45', and the driving bracket 45 'is used for supporting and stabilizing the magnetic assembly 42'. The driving bracket 45 'is pivotally engaged with the magnetic conductive cavity 41', so that the driving bracket 45 'can be driven to displace the magnetic group 42' relative to the central pillar 44 'in the magnetic conductive cavity 41'. Of course, in other embodiments, the driving bracket 45 'may be fixed, and the magnetic conductive cavity 41' may be driven to displace.

The kinetic energy generating device 40 ' further includes a driving member 46 ' connected to the driving bracket 45 ', and the driving bracket 45 ' can be driven when an external force is applied to the driving member 46 '. Preferably, the drive element 46 'can be integrally injection molded with the drive bracket 45'. In particular, the driving element 46 ' may be implemented as a spring plate in this embodiment, and the spring plate is also used to increase potential energy and accelerate the movement speed of the magnetic assembly 42 ' of the kinetic energy generating device 40 '.

The kinetic energy generating device 40 ' further includes a reset element 47 ', the reset element 47 ' accumulates potential energy when the driving element 46 ' drives the driving bracket 45 ' and drives the magnet assembly 42 ' to displace, and when the external force applied to the driving element 46 ' disappears or decreases to a predetermined magnitude, the reset element 47 ' can make the driving element 46 ' return to the initial position, so that the magnet assembly 42 ' returns to the initial position, and the center pillar 44 ' again alternately contacts the top magnetizer 422 ' and the bottom magnetizer 423 ', so that another induced current can be generated again.

In this embodiment of the invention, the drive cover 12 'and the key cover 11' are pivotably arranged with respect to each other to achieve a one-sided oscillation. Specifically, as shown in fig. 16, the driving cover 12 'includes a driving cover body 121' and a triggering member 122 'convexly disposed on an inner surface of the driving cover body 121' for pressing against the driving member 46 'to drive the magnetic assembly 42'. The driving cover 12 ' is provided with a front and a rear clamping groove 124 ' respectively, and the cloth key cover 11 ' is provided with a clamping shaft 113 ' at a position corresponding to the clamping groove 124 ', so that the cloth key cover 11 ' can be pivotally jointed with the driving cover 12 ' through the matching of the clamping groove 124 ' and the clamping shaft 113 '. It is understood that the latch shaft 113 ' may be disposed on the driving cover body 121 ' of the driving cover 12 ', and the latch groove 124 ' is disposed on the key arranging cover 11 '.

As shown in the drawings, the left side of the driving cover 12 ' further includes a hook 123 ' slidably engaged with the cloth key cover 11 ' for fixing and limiting. If the inner side of the key arranging cover 11 'is formed with a corresponding sliding slot 112', the hook 123 'is slidably disposed on the sliding slot 112'. It is understood that the hook 123 'may be disposed on the key arranging cover 11' and the sliding groove 112 'is disposed on the driving cover 12'. The slide groove 112 'may also be provided on the outer surface of the key cover 11', i.e. the drive cover 12 'may also be located on the outer side of the key cover 11' instead of the drive cover 12 'being located on the inner side of the key cover 11' as shown in fig. 17.

It is worth mentioning that in this embodiment of the present invention, as shown in fig. 17 and 18, the driving cover 12 'and the key arranging cover 11' are in a one-side swing type. That is to say, the self-generating remote controller adopts one end draw-in groove formula to connect fixedly, and the other end can swing. The connection mode can be similar to a stapler, and one end of the connecting device can move up and down and one side. Therefore, the self-generating remote controller is stable in structure and suitable for being installed on the surface of a wall body for operation of operators. In this preferred embodiment, a pivotal connection structure, i.e. the latch shaft 113 'and the latch slot 124', may be provided on the other side of the autonomous electric remote control, the end of the cloth key cover 11 'remote from the pivotal connection structure being adapted to be pressed so as to be pivotally moved relative to the latch shaft 113'.

Further, when the self-generating remote controller is installed on a wall W, when the key cover 11 ' is pressed, the driving cover 12 ' is supported by the wall W without displacement, and the key cover 11 ' is relatively displaced by the pressing, i.e. pivoted around the clamping shaft 113 ', so that the driving cover 12 ' is recessed in the key cover 11 ' (of course, when the key cover 11 ' is disposed inside the driving cover 12 ', the key cover 11 ' may be recessed toward the inside of the driving cover 12 '), i.e. the driving cover 12 ' is opposite to the key cover 11 ', and the triggering element 122 ' abuts against the driving element 46 ' to make the kinetic energy generating device 40 ' convert the mechanical kinetic energy into the electrical energy to generate the power. When a pressing force is applied to the key 21 ', the driving cover 12 ' is supported by the wall surface W and does not displace relatively, but the driving cover 12 ' and the key distribution cover 11 ' can be opposite, so that the triggering element 122 ' causes the driving element 46 ' to displace, and power generation of the kinetic energy power generation device 40 ' is also realized. Similarly, the kinetic energy power generator 40 'can generate power again by the reset action of the reset element 47', and can transmit a second wireless control signal.

It should be noted that, in this embodiment of the present invention, compared with the above preferred embodiment of the present invention, which applies the infrared emitting diode, the self-generating remote controller may adopt a mode of infrared emitting wireless signals, or may not adopt the infrared emitting diode. Because, for the self-generating remote controller fixed on the wall surface, the wireless radio frequency mode is adopted for remote control without directional limitation, and the remote controller is more convenient. Of course in

Accordingly, this preferred embodiment of the present invention provides a wireless signal transmission method of a self-generating remote controller, which includes the steps of:

when at least one key 21 'of the key device 20' is pressed, the control command circuit of the controller 30 'corresponding to the key 21' is turned on;

when the key arrangement cover 11 'is pressed, the key arrangement cover 11' and the driving cover 12 'generate relative displacement, and the kinetic energy generating device 40' is driven to convert mechanical energy into electric energy; and

the controller 30 ' transmits a wireless control signal corresponding to the key 21 ' under the power supply provided by the kinetic energy generating device 40 '.

In other words, in the invention, the two cover bodies generate relative displacement, so that the kinetic energy generating device is driven to generate electric energy. In this preferred embodiment, the kinetic energy generating device 40 'engaged with the driving cap 12' is driven to generate electric energy.

Accordingly, when the pressing force applied to the cloth key cover 11 ' is removed, the reset element 47 ' is restored from elastic deformation, so that its reset action causes the magnetic group 42 ' disposed in the driving bracket 45 ' to return to the original position, so that the center pillar 44 ' again alternately contacts the bottom magnetizer 423 ' and the top magnetizer 422 ' of the magnetic group 42 ', so that the kinetic energy generating device 40 ' again generates electric energy, and if the key 21 ' is still pressed, the controller 30 ' can again issue another wireless control signal.

when the key arrangement cover 11 ' is pressed, the driving cover 12 ' and the key arrangement cover 11 ' are relatively displaced, so that the magnetic group 42 ' and the central pillar 44 ' and the magnetic group 42 ' located in the magnetic conductive cavity 41 ' are relatively displaced, and the central pillar 44 ' alternately contacts the top magnetizer 422 ' and the bottom magnetizer 423 ' of the magnetic group 42 ', thereby generating a primary induced current in the coil 43 ' disposed around the central pillar 44 '. Accordingly, the coil 43 ' and the central pillar 44 ' are located in the magnetic conductive cavity 41 ', and the coil 30 ' is completely covered by the magnetic induction lines, so that the magnetic leakage of the whole magnetic circuit system is reduced, and the power generation efficiency of the whole kinetic energy power generation device 40 ' of the self-generating remote controller is improved.

When the key cover 11 'is no longer pressed, the reset action of the reset element 47' causes the center leg 44 'to alternately contact the bottom magnetizer 423' and the top magnetizer 422 'of the magnet assembly 42', thereby generating another induced current in the coil 43 'disposed around the center leg 44'.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
