Description

Technical Field

[0001] This utility model relates to the field of passive switches, and in particular to a rotor generator with an embedded ultra-miniature self-generating module. Background Technology

[0002] Switches, as crucial control components in the field of electrical equipment, are used to control the operating status of other electrical devices in a circuit, such as controlling the on / off state of electrical appliances like lights and doorbells. Existing electrical equipment switches mainly include wired and wireless control switches. Wired control switches are electrically connected to the operating circuit of the electrical device; however, they have several drawbacks, such as wasted wiring and cumbersome installation. Wireless control switches, on the other hand, communicate with the electrical device in the circuit using a wireless receiver while powered by a battery. They control the device's operating status wirelessly, overcoming many of the drawbacks of wired switches, such as wasted wiring. However, because wireless control switches rely on energy storage devices such as dry cell batteries or lithium batteries, they require periodic battery replacements, undoubtedly increasing resource waste and environmental pollution.

[0003] To address the shortcomings of current wired and wireless control switches, passive wireless control switches, such as passive wall switches, have emerged on the market. These switches utilize the mechanical force of a finger pressing the switch panel to drive a magnet and coil to make a relative movement, generating a very short electrical pulse. This pulse then drives the wireless transmitting circuit to transmit a short string of codes, thus controlling the state of the terminal device passively without relying on battery power, which has significant environmental advantages.

[0004] However, compared to switches with continuous battery power, the drawback of the passive wireless switch is that the energy generated by the generator is extremely short-lived after each actuation, limiting the applications of current passive controller products. Most current passive wireless switches use a lever mechanism where a permanent magnet and a coil interact to generate electricity. Because the pressure applied by each operator varies, these switches often incorporate a spring-loaded buffer to ensure successful triggering of the lever motion. The operator's force must overcome the elastic deformation of the spring to trigger the lever motion, resulting in instantaneous triggering and consequently, instantaneous energy generation. For example, Chinese utility model patent CN106462127B discloses a self-generating wireless switch where each actuation of the switch plate drives a micro-generator to produce voltage. Typically, the energy generated by the micro-generator after a single actuation of the switch plate lasts for 1.5ms. Figure 1 As shown, in a single operation, the self-generated wireless switch produces a single pulse of energy, with a maximum duration of 2ms. Even with repeated charging and discharging of the micro-generator via an energy storage device, the operating time of the self-generated wireless switch can only be extended to approximately 6ms. In other words, the current passive wireless control switches have a maximum power supply time of less than 10ms, which severely limits their communication capabilities. The short transmission time of current passive wireless control switches leads to poor security and incompatibility with standard communication protocols, such as WiFi communication.

[0005] Currently, the method to improve the mechanical energy utilization of existing passive wireless switches is to utilize the two actions of pressing and releasing the switch separately. A pulse of energy is generated when the switch is pressed, and another pulse is generated when it is released to reset the circuit. However, the generated energy is only enough for the corresponding communication circuit to send 2-3 32-bit data signals at a time, which is insufficient to support the passive wireless switch in data reception, device identification, and binding processes. In actual operation, the duration of a single press and release action is typically around 200-900ms, while the existing passive wireless switch can only output energy for less than 10ms. This means that the mechanical energy during the operation is not being fully utilized, and most of the mechanical energy is wasted.

[0006] While some piezoelectric ceramic generators can continuously generate weak electrical energy based on sustained vibration, the instantaneous energy density and power of these generators are extremely low. They require a considerable amount of time to accumulate energy before reaching a usable voltage for the circuit. This accumulation period typically lasts several seconds or even tens of seconds, making it impossible to provide usable energy instantly during operation. However, in many applications, users are accustomed to instantaneous use, such as controlling lights with a wall switch. Users expect the light's status to change immediately upon pressing the button, rather than waiting several seconds for the control effect to occur. This is clearly not user-friendly. Therefore, even if a piezoelectric ceramic generator can output energy for a relatively long time, the energy required for storage is only sufficient for a short period and cannot sustain the circuit's operation while the generator is continuously generating power.

[0007] Furthermore, with the rise of the smart home market, various smart wireless devices are widely used. However, these smart devices all use standard communication protocols, such as WiFi and Bluetooth protocols. But as mentioned earlier, the power supply time of the existing passive wireless switches is too short to complete the pairing process with WiFi and Bluetooth devices. They can only send simple codes or generate Beacon broadcast protocols, which do not provide sufficient security, thus limiting the application of the current passive wireless switches.

[0008] Meanwhile, the short power supply time of the existing passive wireless switches directly affects product upgrades. Currently, many new switches on the market use capacitive touch to generate button commands. However, since the touch chip needs 400ms-800ms to complete the calibration of the corresponding command after being powered on, while the power supply time of the existing passive wireless switches is only a few milliseconds, it is obviously insufficient to maintain the acquisition of touch commands. Therefore, the current new switches that use capacitive touch to generate button commands can only be forced to use active power supply, and cannot use passive technology to obtain the advantages in daily maintenance and environmental protection.

[0009] One objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the self-generating module can continuously generate multiple pulses of energy after being operated once, thereby extending its energy output time and ensuring sufficient energy supply.

[0010] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the self-generating module is continuously operated to generate electricity during operation by the operator, and has a high efficiency in utilizing mechanical energy.

[0011] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component and power generation method, wherein the self-generating module can generate electricity instantaneously when driven by an external force, so as to meet the user habit of "press and use" while being able to continuously output energy.

[0012] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method. The self-generating module includes a pivot drive arm, the speed-increasing component, and the rotor generator. The pivot drive arm is pivoted under the drive of an external force. The speed-increasing component is coupled to the pivot drive arm and the rotor generator to transfer the pivoting kinetic energy of the pivot drive arm to the rotor generator under the force of pivoting, thereby converting it into the rotational kinetic energy of the rotor generator, which in turn drives the rotor generator to generate electrical energy, thus continuously converting mechanical energy into electrical energy.

[0013] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein, corresponding to one actuation of the pivot drive arm, the rotor generator is driven to generate multiple pulse energies.

[0014] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the rotor generator includes a magnetic wheel, wherein the magnetic wheel rotates multiple times under a single actuation of the pivot drive arm to repeatedly disturb the magnetic field lines of the rotor generator and generate multiple pulse energy.

[0015] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method, wherein the motion of the pivot drive arm is amplified by the speed-increasing component and output to the rotor generator to improve the power generation efficiency of the self-generating module.

[0016] Another objective of this utility model is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method. The speed-increasing component includes a push rod, a speed-increasing wheel assembly, and an output drive wheel. The push rod is coupled to a pivoting drive arm, and is activated when the pivoting drive arm is pivoted. The speed-increasing wheel assembly has an input wheel and a speed-increasing output wheel. The push rod is coupled to the input wheel, and the speed-increasing output wheel is coupled to the output drive wheel. When the pivoting drive arm is pivoted under force, the pivoting drive arm drives the push rod to advance into the receiving cavity, thereby driving the input wheel. The input wheel then drives the speed-increasing output wheel to increase speed. The output drive wheel is rapidly linked, wherein the output drive wheel and the magnetic wheel are coaxially arranged and the output drive wheel drives the magnetic wheel to rotate when the output drive wheel rotates. The transmission ratio between the speed-increasing wheel set and the output drive wheel is less than 1, thereby enabling the speed-increasing output of the pivot drive arm's motion to the rotor generator to increase the rotational speed of the magnetic wheel. This increases the number of magnetic pole switching of the magnetic wheel in the corresponding magnetic field and helps to accelerate the response speed of the rotor generator to the movement of the pivot drive arm. This allows the rotor generator to generate energy instantaneously while the pivot drive arm is being operated, thereby increasing the pulse energy output of the rotor generator, improving the power generation efficiency of the rotor generator, and meeting the user habit of plug-and-play operation.

[0017] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method. Preferably, the transmission ratio between the speed-increasing wheel set and the output drive wheel is less than or equal to 1 / 4. When the pivot drive arm is driven, the magnetic wheel can be rotated at high speed in conjunction with the motor. On the one hand, this increases the rotational speed of the magnetic wheel to enhance the pulse energy output by the rotor generator. On the other hand, it accelerates the power generation response speed of the rotor generator, satisfying the user's habit of using it immediately upon pressing.

[0018] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method. The stroke of the push rod is amplified and output by the speed-increasing wheel assembly. The input wheel and the output wheel of the speed-increasing wheel assembly are coaxially arranged gears. The diameter of the output wheel is larger than the diameter of the input wheel. The input wheel is engaged with the push rod, causing it to rotate in conjunction with the push rod when it is driven by the pivot drive arm. The output wheel shares the same axis of rotation with the input wheel and rotates at the same speed as the input wheel. Because the output wheel has a larger diameter than the input wheel, it has a greater stroke at the same speed, thus amplifying the stroke of the push rod and outputting it to the output drive wheel. This extends the drive stroke of the rotor generator under the same pressing stroke, increasing the power generation of the rotor generator and ensuring sufficient energy supply.

[0019] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method. The diameter of the speed-increasing output wheel is preferably set to be more than five times the diameter of the input wheel. When the input wheel rotates one revolution in conjunction with the push rod, the corresponding stroke is amplified more than five times by the speed-increasing wheel assembly. This amplifies the stroke of the push rod and outputs it to the output drive wheel. Under the same pressing stroke, the drive stroke of the rotor generator is extended. This benefits both by increasing the number of revolutions of the magnetic wheel, thereby enhancing the pulse energy output by the rotor generator, and by accelerating the rotor generator's response speed to the pivot drive arm, satisfying the user's "press and use" habit.

[0020] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-increasing component, and power generation method. The movement of the pivot drive arm is transmitted to the input wheel via the push rod. The input wheel coaxially drives the speed-increasing output wheel to rotate, amplifying the motion stroke and outputting it to the output drive wheel. The output drive wheel is accelerated by the speed-increasing output wheel, amplifying the motion speed increase to the magnetic wheel. This allows the movement of the pivot drive arm to be amplified and transmitted to the magnetic wheel multiple times. Thus, in a single pressing operation of the pivot drive arm, the rotor generator can generate multiple pulses of energy, ensuring sufficient energy supply.

[0021] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the movement of the pivot drive arm is continuously transmitted via the push rod, that is, during the process of the pivot drive arm being driven, the push rod is continuously pushed by the pivot drive arm rather than momentarily pushed, wherein the pivot drive arm has a chamfered surface, and one end of the push rod is abutted against the chamfered surface, wherein when the pivot drive arm is pivoted under force, the end of the push rod is continuously pushed by the pivot drive arm along the chamfered surface, thereby extending the driving time of the rotor generator, so that the actuation time of the pivot drive arm can be continuously transmitted to drive the rotor generator, so as to maintain the continuous power generation of the rotor generator rather than generating instantaneous electrical energy, thereby extending the power supply time of the rotor generator to enable the self-generating module to work continuously.

[0022] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the push rod has a push rack, wherein the push rack is disposed on the side of the push rod in the radial direction, wherein the push rod and the push rack are engaged with the input wheel, so that when the push rod is pushed, the input wheel rotates along the push rack and is linked by the push rod, wherein the push rack is close to the other end of the push rod, which is beneficial to the structural layout of the self-generating module.

[0023] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method. The rotor generator includes a generating cavity, a drive shaft, and at least one coil winding. The magnetic wheel and the output drive wheel are coaxially arranged and rotate around the drive shaft. The magnetic wheel is rotatably housed in the generating cavity to isolate it by the generating cavity covering it, thereby effectively preventing the magnetic wheel from being affected by the external environment during rotation, ensuring smooth rotation of the magnetic wheel, and also improving the response speed of the rotor generator.

[0024] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the coil winding is wound around the power generation cavity and supported by the power generation cavity, and is designed without an iron core, thereby avoiding the influence of the coil iron core on the magnetic wheel, avoiding the magnetic wheel being affected by magnetic attraction, ensuring that the rotor generator can respond to the movement of the pivot drive arm in a timely manner, and helping to reduce the driving force of the self-generating module.

[0025] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the power generation cavity is made of a non-magnetic material, thereby avoiding magnetic attraction between the power generation cavity and the magnetic wheel, ensuring that the magnetic wheel can rotate at high speed in the power generation cavity, and facilitating that the rotor generator can respond to the movement of the pivot drive arm in a timely manner.

[0026] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the magnetic wheel is preferably designed in the form of a disc, so that the rotation coverage area of ​​the magnetic wheel is consistent with the actual area of ​​the magnetic wheel. Therefore, the power generation cavity does not need to reserve additional space for the rotation of the magnetic wheel, which is beneficial to increasing the volume ratio of the magnetic wheel to the power generation cavity and to miniaturizing the rotor generator.

[0027] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the magnetization direction of the magnetic wheel is radial, that is, the two poles of the magnetic wheel are distributed on both sides of the magnetic wheel along the diameter direction of the magnetic wheel. When the magnetic wheel rotates in the power generation cavity, the magnetic field lines of the magnetic wheel can be disturbed by the coil windings wound around the power generation cavity, thereby ensuring the energy output stability of the rotor generator.

[0028] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the power generation cavity includes a first half-cavity and a second half-cavity, wherein the first half-cavity and the second half-cavity are detachably spliced ​​together, so that the power generation cavity based on the split splicing design facilitates the assembly of the rotor generator and helps to improve the corresponding production efficiency.

[0029] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method. The speed-up component includes a reverse thrust member, which is abutted against the push rod and accumulates potential energy when the push rod is linked by the pivot drive arm. The potential energy is released when the force on the pivot drive arm is removed, thereby pushing the push rod in the opposite direction. This causes the speed-up wheel set to rotate in the opposite direction. The speed-up wheel set amplifies the reset stroke of the push rod and outputs it to the rotor generator, so that the rotor generator can generate multiple pulses of energy again, thereby increasing the output energy of the self-generating module and extending the energy output time of the rotor generator.

[0030] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the push rod has a hollow section, the hollow section is hollowly designed to define a force-guiding cavity, wherein the reverse thrust member is disposed in the force-guiding cavity, thereby being limited by the force-guiding cavity to guide the direction of the force applied by the push rod to the reverse thrust member, and the reverse thrust direction of the reverse thrust member, ensuring the linkage stability of the push rod to the speed-up wheel assembly.

[0031] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the pivot drive arm has a drive section and two connecting sections extending from both ends of the drive section, and a power generation movement opening is formed between the drive section and the two connecting sections. The pivot drive arm is pivotally connected to two opposite side walls of the housing via the two connecting sections to encircle the housing, so that the speed-up component and the rotor generator are disposed in the power generation movement opening, thereby improving the structural compactness of the self-generating module and facilitating the miniaturization of the self-generating module.

[0032] Another objective of this invention is to provide a self-generating module and its rotor generator, speed-up component, and power generation method, wherein the oblique surface is provided in the drive section, and the push rod is pushed by the pivot drive arm in the drive section, ensuring the kinetic energy of the pivot drive arm in conjunction with the push rod, and based on the pivot drive arm in conjunction with the push rod in the drive section with the largest stroke, the stroke of the pivot drive arm driving the push rod is increased, thereby increasing the energy output of the rotor generator.

[0033] According to one aspect of the present invention, a rotor generator is provided, wherein the rotor generator comprises:

[0034] A power generation cavity, wherein the power generation cavity defines a power generation cavity;

[0035] A magnetic wheel, wherein the magnetic wheel is rotatably housed in the power generation cavity, wherein the magnetization direction of the magnetic wheel is the radial direction of the magnetic wheel; and

[0036] At least one coil winding, wherein the coil winding is wound around the power generation cavity outside the power generation cavity, so as to generate electrical energy based on the principle of electromagnetic induction when the magnet wheel rotates in the power generation cavity.

[0037] In one embodiment, the magnetic wheel is designed in the form of a disk.

[0038] In one embodiment, the number of coil windings is two, and the two coil windings are respectively named a first coil winding and a second coil winding, and the first coil winding and the second coil winding are wound side by side in the power generation cavity.

[0058] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0059] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0060] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0061] Refer to the accompanying drawings in the specification of this utility model. Figures 2 to 10 An embodiment of the present invention is illustrated with a self-generating module. Compared to existing technologies where a single instantaneous pulse generated by pressing can only support the operation of a wireless transmitter with a power of 0dB for a few milliseconds, the self-generating module provided by the present invention can continuously generate multiple pulses of energy after a single operation, enabling a wireless transmitter with a power of 0dB to maintain operation for more than 100ms. Compared to existing passive control switches, it has significant advantages in power generation, efficiency, and energy duration. Therefore, it is suitable for achieving higher communication standards, allowing the corresponding self-generating switch to connect to the Internet using international standard communication protocols, thus integrating the self-generating switch into smart home systems. This is of great significance to the development of the self-generating switch field.

[0062] Specifically, the self-generating module includes a housing 10, a pivot drive arm 20, a speed-increasing component 30, a rotor generator 40, and a communication circuit 50. The housing 10 defines a receiving cavity 101. The pivot drive arm 20 is pivotally disposed outside the receiving cavity 101 on the housing 10. The speed-increasing component 30 and the rotor generator 40 are housed in the receiving cavity 101 and can be linked by the movement of the pivot drive arm 20. The speed-increasing component 30 transmits the speed-increasing motion of the pivot drive arm 20 to the rotor generator 40 to drive the rotor generator 40 to rotate at high speed and continuously generate multiple pulses of energy. The communication circuit 50 is housed in the receiving cavity 101 and is powered and connected to the rotor generator 40 so that it can be powered by the rotor generator 40 to operate.

[0063] In detail, the speed-increasing assembly 30 includes a push rod 31, a speed-increasing wheel set 32, and an output drive wheel 33. The speed-increasing wheel set 32 ​​and the output drive wheel 33 are housed in the receiving cavity 101 and are linked together. The push rod 31 is linked to the speed-increasing wheel set 32 ​​and one end extends out of the receiving cavity 101. The pivot drive arm 20 is linked to the end of the push rod 31 and has an abutment position that abuts against the push rod. The rotor generator 40 includes a magnetic wheel 41, a generator cavity 42, and at least one coil winding 43. The magnetic wheel 41 is connected to the output drive wheel 33. The shaft linkage state is housed in a power generation cavity 420 defined by the power generation cavity 42, wherein the coil winding 43 is wound around the power generation cavity 42 outside the power generation cavity 420. When the pivot drive arm 20 is pivoted under force, the position of the abutment position of the pivot drive arm 20 changes, driving the push rod 31 to advance into the receiving cavity 101 and linking the speed-increasing wheel set 32. The speed-increasing wheel set 32 ​​links the output drive wheel 33 and links the magnetic wheel 41 to rotate in the power generation cavity 420, so as to generate electrical energy with the coil winding 43 based on the principle of electromagnetic induction, so that the rotor generator 40 generates pulse energy.

[0064] It is worth mentioning that the pressing stroke of the pivot drive arm 20 is amplified and transmitted to the rotor generator 40 by the speed-increasing component 30 in multiple stages. This allows the magnetic wheel 41 to rotate at high speed multiple times in the power generation chamber 420 to generate multiple pulses of energy under a single press of the pivot drive arm 20. In other words, under the same pressing stroke, the pivot drive arm 20 can drive the rotor generator 40 to generate multiple pulses of energy, thereby increasing the power generation of the rotor generator 40 and meeting higher energy consumption requirements.

[0065] Specifically, the stroke of the pivot drive arm 20 is amplified when the push rod 31 is linked to the speed-increasing wheel set 32. The speed-increasing wheel set 32 ​​has an input wheel 321 and a speed-increasing output wheel 322. The push rod 31 is coupled to the input wheel 321, and the speed-increasing output wheel 33 is coupled to the output drive wheel 322. When the pivot drive arm 20 is pivoted under force, the position of the abutment position of the pivot drive arm 20 changes, driving the push rod 31 to advance into the receiving cavity and linking the input wheel 321. The input wheel 321 links the speed-increasing output wheel 322 to speed up the output drive wheel 33, thereby linking the magnetic wheel 41 to rotate in the power generation cavity 420 to generate electrical energy based on the principle of electromagnetic induction and the coil winding 43.

[0066] In this embodiment of the present invention, the input wheel 321 and the output wheel 322 of the speed-increasing wheel set 32 ​​are configured as coaxial gears. The diameter of the output wheel 322 is larger than that of the input wheel 321. The input wheel 321 is engaged with the push rod 31 so that it is rotated by the push rod 31 when the push rod 31 is pushed into the receiving cavity 101 by the pivot drive arm 20. The output wheel 321 and the input wheel 322 have the same axis of rotation and rotate at the same speed as the input wheel 322. Since the diameter of the output wheel 321 is larger than that of the input wheel 322, the output wheel 321 has a larger circumferential stroke than the input wheel 322 at the same speed, thereby amplifying the stroke of the push rod 31 and outputting it to the output drive wheel 33. This extends the drive stroke of the rotor generator 40 under the same pressing stroke, increases the power generation of the rotor generator 40, and ensures sufficient energy supply.

[0067] Preferably, the diameter of the speed-increasing output wheel 322 is set to be more than five times the diameter of the input wheel 321, that is, the ratio between the diameter of the speed-increasing output wheel 322 and the diameter of the input wheel 321 is greater than or equal to 5. When the input wheel 321 is rotated one revolution by the push rod 31, the corresponding stroke is amplified more than five times by the speed-increasing wheel set 32. In this way, the movement stroke of the push rod 31 can be amplified and output to the output drive wheel 33. Under the same pressing stroke, the drive stroke of the rotor generator 40 is extended. On the one hand, this is beneficial to increase the number of revolutions of the magnetic wheel 41, thereby enhancing the pulse energy output by the rotor generator 40. On the other hand, it is beneficial to accelerate the movement response speed of the rotor generator 40 to the pivot drive arm 20, satisfying the user's habit of pressing and using immediately.

[0068] Furthermore, the linkage of the pivot drive arm 20 is amplified when the speed-increasing wheel set 32 ​​is linked to the output drive wheel 33, and the transmission ratio between the speed-increasing wheel set 32 ​​and the output drive wheel 33 is less than 1, thereby enabling the speed-increasing motion of the pivot drive arm 20 to be output to the rotor generator 40.

[0069] Specifically, the speed-increasing output wheel 322 of the speed-increasing wheel set 32 ​​meshes with the output drive wheel 33, and the transmission ratio between the speed-increasing output wheel 322 and the output drive wheel 33 is less than 1. When the speed-increasing output wheel 322 rotates in conjunction with the output drive wheel 33, the speed of the output drive wheel 33 will be increased, and the speed of the magnetic wheel 41, which is coaxially arranged with the output drive wheel 33, will also be increased. This increases the number of magnetic pole switching of the magnetic wheel 41 in the corresponding magnetic field and helps to accelerate the response speed of the rotor generator 40 to the movement of the pivot drive arm 20. That is, when the pivot drive arm 20 is driven, the corresponding mechanical energy is rapidly amplified and output to the rotor generator 40 to drive the rotor generator 40 to rotate at high speed. This allows the rotor generator 40 to rotate at high speed instantaneously while the pivot drive arm 20 is operated, so that the coil winding 43 generates energy. This increases the pulse energy output by the rotor generator 20, improves the power generation efficiency of the rotor generator 20, and meets the user habit of plug-and-play.

[0070] Preferably, the transmission ratio between the speed-increasing output wheel 322 and the output drive wheel 33 is less than or equal to 1 / 4. In this case, when the pivot drive arm 20 is driven, the magnetic wheel 41 can be rotated at high speed in conjunction with the magnetic wheel 41. This increases the rotational speed of the magnetic wheel 41 to enhance the pulse energy output by the rotor generator 40, and also speeds up the power generation response of the rotor generator 40, thus satisfying the user's habit of using it immediately.

[0071] In other words, the movement of the pivot drive arm 20 is transmitted to the input wheel 321 via the push rod 31. The input wheel 321 coaxially drives the speed-increasing output wheel 322 to rotate. The larger diameter speed-increasing output wheel 322 is coaxially driven by the smaller diameter input wheel 321 and rotates at the same speed as the input wheel 321, thus amplifying the motion stroke and outputting it to the output drive wheel 33. The output drive wheel 33 is accelerated by the speed-increasing output wheel 322. That is, when the speed-increasing output wheel 322 rotates one revolution, the output drive wheel 33 is driven by the speed-increasing output wheel 322 to rotate several revolutions, thereby amplifying the motion speed increase to the magnetic wheel 41. In this way, the movement of the pivot drive arm 20 is amplified and transmitted to the magnetic wheel 41 multiple times. So that when the pivot drive arm 20 is pressed once, the rotor generator 40 can generate multiple pulse energy, ensuring sufficient energy supply and accelerating the power generation response speed of the rotor generator 40.

[0072] Furthermore, the speed-increasing wheel assembly 32 includes a shared shaft 323, wherein the input wheel 321 and the speed-increasing output wheel 322 share the shared shaft 323 and are coaxially arranged, wherein the physical center points of the input wheel 321 and the speed-increasing output wheel 322 are arranged along the axial direction of the shared shaft 323, wherein the housing 10 includes an upper cover 11 and a lower housing 12, wherein the lower housing 12 is provided with a shaft slot 123, wherein one end of the shared shaft 323 is inserted into the shaft slot 123, so that the speed-increasing wheel assembly 32 is rotatably installed in the receiving cavity 101, wherein the upper cover 11 is provided with a shaft insertion hole 111, wherein the other end of the shared shaft 322 is inserted into the shaft insertion hole 111, thereby ensuring the installation stability of the speed-increasing wheel assembly 32.

[0073] Specifically, the movement of the pivot drive arm 20 pushes the push rod 31 continuously. That is, during the movement of the pivot drive arm 20, the movement of the push rod 31 is continuous along with the movement of the pivot drive arm 20, rather than being momentarily displaced when the pivot drive arm 20 is pressed or momentarily driven to displace when the pivot drive arm 20 is pressed to a certain position. This is beneficial to improving the utilization rate of the mechanical energy duration of the pivot drive arm 20, so that the power generation duration of the rotor generator 40 can match the actuation duration of the pivot drive arm 20.

[0074] In other words, the movement of the pivot drive arm 20 is continuously transmitted through the push rod 31, meaning that during the process of the pivot drive arm 20 being driven, the push rod 31 is continuously pushed by the pivot drive arm 20 rather than being pushed instantaneously.

[0075] In one embodiment, the pivot drive arm 20 has a chamfered surface 210, and the end of the push rod 31 extending from the receiving cavity 101 abuts against the chamfered surface 210. When the pivot drive arm 20 is pivoted under force, the end of the push rod 31 displaces relative to the chamfered surface 210 to form the abutment position, thereby continuously pushing the push rod 31 by the pivot drive arm 20. Specifically, initially, one side of the chamfered surface 210 of the pivot drive arm 20 abuts against the end of the push rod 31. When the pivot drive arm 20 is pivoted under force, the push rod 31 moves relative to the chamfered surface 210 to the other side of the chamfered surface 210 and is continuously pushed by the pivot drive arm 20. The pusher continuously pushes the push rod 31, causing the speed-increasing wheel assembly 32 to rotate continuously, which in turn drives the output drive wheel 33 to rotate continuously, thereby causing the magnetic wheel 41 to rotate continuously. This extends the driving time of the rotor generator 40, allowing the actuation time of the pivot drive arm 20 to be continuously transmitted to drive the rotor generator 40, thus maintaining the continuous power generation of the rotor generator 40. Therefore, the rotor generator 40 can continuously generate power under the single drive of the pivot drive arm 20, rather than generating instantaneous electrical energy. This extends the power supply time of the rotor generator 40 to power the self-generating module to work continuously, making it suitable for achieving higher standard communication and facilitating interconnection with devices using standard communication protocols.

[0076] In particular, the movement of the pivot drive arm 20 pushes the push rod 31 continuously. According to the disclosure of this utility model, there can be a variety of mechanical transmission methods between the two, and this utility model is not limited to any one of them.

[0077] Furthermore, the push rod 31 has a push rack 311, wherein the push rack 311 is disposed on the side of the push rod 31 in the radial direction of the push rod 31, wherein the push rod 31 is engaged with the input wheel 321 by the push rack 311, so that when the push rod 31 is pushed, the input wheel 321 rotates along the push rack 311 and is linked by the push rod 31, wherein the push rack 311 is close to the other end of the push rod 31, which is beneficial to the structural layout of the self-generating module and ensures the structural compactness of the self-generating module.

[0078] Specifically, to fully utilize mechanical energy, the speed-increasing component 30 includes a reverse thrust member 34, which abuts against the push rod 31. The reverse thrust member 34 accumulates potential energy when the push rod 31 is linked to the pivot drive arm 20, and releases this potential energy when the pivot drive arm 20 is no longer under force, thus pushing the push rod 31 in the opposite direction. This causes the speed-increasing wheel set 32 ​​to rotate in the opposite direction. The speed-increasing wheel set 32 ​​amplifies the reset stroke of the push rod 31 and outputs it to the rotor generator 40, enabling the rotor generator 40 to generate multiple pulses of energy again. This increases the output energy of the self-generating module and extends the energy output time of the rotor generator. Therefore, in the two movements of pushing the push rod 31 forward and the reverse thrust member 34 pushing the push rod 31 backward, the rotor generator 40 generates two rotational power generation actions, further increasing the generated energy and extending the energy retention time.

[0079] It is worth mentioning that, in order to ensure the accuracy of the force direction applied by the thrust reverser 34 to the push rod 31 and to ensure the force balance of the thrust reverser 34, in this embodiment of the present invention, the thrust reverser 34 is also guided. Specifically, the push rod 31 has a hollow section 312, which is hollowly designed to define a force guiding cavity 3120. The thrust reverser 34 is disposed in the force guiding cavity 3120, with one end inserted into the force guiding cavity 3120 and the other end extending out of the force guiding cavity 3120 and abutting against the housing 10, thereby being limited by the force guiding cavity 3120 to guide the force direction of the push rod 31 on the thrust reverser 34 and the thrust reverser 34's reverse direction, ensuring the force balance of the thrust reverser 34, thereby ensuring the linkage stability of the push rod 31 with the speed-increasing wheel set 34. At the same time, this concealed structure significantly reduces the size of this invention, achieving multiple benefits in one fell swoop.

[0080] Furthermore, in order to ensure the kinetic energy of the pivot drive arm 20 while maintaining the structural compactness of the self-generating module, the pivot drive arm 20 is configured to surround the speed-increasing component 30 and the rotor generator 40.

[0081] Specifically, the pivot drive arm 20 has a drive section 21 and two connecting sections 22 extending from both ends of the drive section 21, and forms a power generation movement opening between the drive section 21 and the two connecting sections 22. The pivot drive arm 20 is pivotally connected to two opposite side walls of the housing 10 via the two connecting sections 22 to encircle the housing 10, so that the speed-increasing component 30 and the rotor generator 40 are arranged in the power generation movement opening, thereby improving the structural compactness of the self-generating module and facilitating the miniaturization of the self-generating module.

[0082] The pivot drive arm 20 is provided with a shaft arm 221 at the end of the two connecting segments 22 away from the drive segment 21. The housing body 10 is provided with a shaft hole 121 on the side wall of the lower housing 12 corresponding to the shaft arm 221. The pivot drive arm 20 is pivotally mounted on the housing body 10 with the shaft arm 221 inserted into the corresponding shaft hole 121. It is understood that in some embodiments, the shaft arm 221 and the shaft hole 121 are interchangeable, that is, the shaft hole 121 is provided in the connecting segment 22 and the shaft arm 221 is provided in the lower housing 12.

[0083] Specifically, in order to maximize the transmission of the movement stroke of the pivot drive arm 20 to the speed-increasing component 30, in this embodiment of the present invention, the oblique surface 210 is preferably provided on the drive section 21. The push rod 31 is pushed by the pivot drive arm 20 on the drive section 21, ensuring the kinetic energy of the pivot drive arm 20 in conjunction with the push rod 31. Based on the pivot drive arm 20 in conjunction with the push rod 31 on the drive section 21 with the largest movement stroke, the stroke of the pivot drive arm 20 driving the push rod 31 is increased, thereby increasing the number of rotations of the magnetic wheel 41 when the pivot drive arm 20 is driven once, and increasing the energy output of the rotor generator 40.

[0084] Furthermore, the rotor generator 40 ensures the smooth rotation of the magnetic wheel 41, reducing the driving force required to drive the magnetic wheel 41 and improving the operator's pressing feel. The magnetic wheel 41 is rotatably housed in the power generation cavity 42, isolating the magnetic wheel 41 by covering it with the power generation cavity 42. This effectively prevents the magnetic wheel 41 from being affected by the external environment during rotation and also helps prevent external impurities such as iron filings from entering the power generation cavity 420, thus ensuring the smooth rotation of the magnetic wheel 41. It also helps the speed-increasing component 30 to quickly drive the magnetic wheel 41 to rotate, improving the response speed of the rotor generator 40.

[0085] It is worth mentioning that the rotor generator 40 includes a drive shaft 44, wherein the magnetic wheel 41 is suspended and supported by the drive shaft 44 in the generator cavity 420, wherein the magnetic wheel 41 and the output drive wheel 33 are coaxially arranged and rotate about the drive shaft 44, wherein the drive shaft 44 passes through the physical center point of the magnetic wheel 41 and the driven shaft 33, wherein the physical center points of the magnetic wheel 41 and the driven shaft 33 are arranged along the axial direction of the coaxial shaft 323, wherein the generator cavity 42 has a pivot hole 422 communicating with the generator cavity 420, wherein one end of the drive shaft 44 extends out of the generator cavity 420 from the pivot hole 422 and is connected to the output drive wheel 33, so that the output drive wheel 33 is disposed outside the generator cavity 420 and can drive the magnetic wheel 41 enclosed by the generator cavity 42 to rotate.

[0086] Furthermore, the power generation cavity 42 has a rotating shaft groove 4201 opposite to the rotating shaft hole 422, and the other end of the drive shaft 44 is inserted into the rotating shaft groove 4201 and installed in the power generation cavity 42. This ensures the installation stability of the drive shaft 44 and helps to reduce the resistance of the rotation of the magnetic wheel 41. The upper cover 11 is further provided with another insertion shaft hole 111, and the end of the drive shaft 44 extending from the power generation cavity 420 is inserted into the insertion shaft hole 111 to ensure the installation stability of the output drive wheel 33 and the magnetic wheel 41.

[0087] Specifically, the power generation cavity 42 further has a pin protrusion 423 opposite to the pivot hole 422. On the one hand, the pin protrusion 423 defines the pivot groove 4201 in the power generation cavity 420. On the other hand, the pin protrusion 423 improves the installation stability of the power generation cavity 42. The lower box 12 has a pin hole 124. The power generation cavity 42 is installed on the box body 10 with the pin protrusion 423 inserted into the pin hole 124. The pin protrusion 423 and the pin hole 124 are limited to improve the installation stability of the power generation cavity 42.

[0088] It is worth mentioning that, for the purpose of improving the installation stability of the rotor generator 40, the lower box 12 further has a limiting wall 125, wherein the limiting wall 125 extends upward from the bottom of the lower box 12, thereby defining an installation cavity 102 in the receiving cavity 101, wherein the rotor generator 40 is installed in the installation cavity 102 and limited by the limiting wall 125, so that the installation stability of the rotor generator 40 is ensured by the limiting wall 125, the pin hole 124 and the shaft hole 111 jointly limiting the rotor generator 40.

[0089] Specifically, in this invention, a light operating feel and extremely high instantaneous response speed are also technical problems that the rotor generator 40 needs to solve. Because this invention uses the speed-increasing component 30, the initial starting torque of the magnetic wheel 41 directly affects the driving force of the pivot drive arm 20. If the magnetic wheel 41 is constrained by other factors, it cannot quickly generate high-speed rotation within less than 30 milliseconds, thus preventing the coil from outputting the rated voltage. Furthermore, if the magnetic wheel 41 is constrained by other factors, after being amplified by each stage of gears, the pivot drive arm 20 becomes difficult to press, rendering this invention impractical.

[0090] Furthermore, to reduce the influence of external factors on the magnetic wheel 41 and ensure that the magnetic wheel 41 can rotate at high speed immediately upon startup, the coil winding 43 is designed without an iron core. That is, this utility model application uses an air-core coil. The coil winding 43 is wound around the power generation cavity 42 and supported by the power generation cavity 42 without an iron core. This avoids the magnetic attraction force generated by the coil core on the magnetic wheel 41, preventing the magnetic wheel 41 from being unable to rotate at high speed instantly. This ensures that the rotor generator 40 can respond to the movement of the pivot drive arm 20 in a timely manner and helps to reduce the driving force of the self-generating module.

[0091] It is worth mentioning that in the existing understanding of micro-generators with self-generating switches, coil windings are wound on an iron core to increase magnetic induction intensity or energy density. However, unlike the existing technology, the high-speed rotation of the magnetic wheel 41 is a key factor in increasing the power output of the rotor generator 40. Therefore, the coreless design of the coil winding 43 helps to ensure the high-speed rotation of the magnetic wheel 41. Furthermore, when pressing the pivot drive arm 20, the corresponding mechanical energy is not lost in overcoming the magnetic attraction between the magnetic wheel 41 and the iron core, which can improve the operator's pressing feel, improve the utilization rate of mechanical energy, and facilitate the rapid response rotation of the magnetic wheel 41.

[0092] Furthermore, also based on reducing the influence of external factors on the magnetic wheel 41 and ensuring that the magnetic wheel 41 can rotate at high speed, the power generation cavity 42 is made of non-magnetic material, thereby avoiding the magnetic attraction between the power generation cavity 42 and the magnetic wheel 41, ensuring that the magnetic wheel 41 can rotate at high speed in the power generation cavity 42, and helping to ensure that the rotor generator 40 can respond to the movement of the pivot drive arm 20 in a timely manner.

[0093] In other words, the magnetic wheel 41 does not generate magnetic attraction with any other component, thereby ensuring that the magnetic wheel 41 can be driven quickly and rotate at high speed, which is beneficial to ensuring the rapid supply of electrical energy of the self-generating module.

[0094] Preferably, to improve space utilization and enhance the miniaturization of the rotor generator 40, the magnetic wheel 41 is designed in the form of a disc. The rotational coverage area of ​​the magnetic wheel 41 is then nearly identical to its actual area. Therefore, the power generation cavity 42 does not need to reserve additional space for the rotation of the magnetic wheel 41, which helps to increase the volume ratio of the magnetic wheel 41 to the power generation cavity 42, thus facilitating the miniaturization of the rotor generator 40 and improving its power generation efficiency.

[0095] In particular, the diameter of the magnetic wheel 41 is larger than the diameter of the output drive wheel 33. During the process of the output drive wheel 33 driving the magnetic wheel 41 to rotate, the stroke of the magnetic wheel 41 at the same speed is amplified, which helps to enhance the power generation efficiency of the rotor generator 40.

[0096] Preferably, the distance between the magnetic wheel 41 and the power generation cavity 42 along the axial direction is less than 5 mm, so as to ensure that the magnetic wheel 41 can rotate in the power generation cavity 420, while taking into account the miniaturization of the rotor generator 40, and to facilitate the proximity of the magnetic wheel 41 and the coil winding 43 to ensure power generation efficiency.

[0097] Preferably, the distance between the magnetic wheel 41 and the power generation cavity 42 in the radial direction is less than 3 mm, so as to ensure that the magnetic wheel 41 can rotate in the power generation cavity 420, while taking into account the miniaturization of the rotor generator 40, and to facilitate the proximity of the magnetic wheel 41 and the coil winding 43, so as to ensure power generation efficiency.

[0098] It is worth mentioning that the magnetization direction F of the magnetic wheel 41 is the radial direction of the magnetic wheel 41, that is, the two poles of the magnetic wheel 41 are distributed on both sides of the magnetic wheel 41 along the diameter direction of the magnetic wheel 41. When the magnetic wheel 41 rotates in the power generation cavity 42, the magnetic field lines of the magnetic wheel 41 can be disturbed by the coil winding wound around the power generation cavity 42, thereby ensuring the energy output stability of the rotor generator 20.

[0099] Specifically, there are two coil windings 43, which are respectively named as the first coil winding 431 and the second coil winding 432. The first coil winding 431 and the second coil winding 432 are wound in parallel in the power generation cavity 42, which helps to improve the power generation efficiency of the rotor generator 40 and to facilitate the miniaturization of the rotor generator 40.

[0100] Specifically, to improve power generation efficiency, the first coil winding 431 and the second coil winding 432 are respectively sleeved on both sides of the magnetic wheel 41, and the hollow portions formed by the first coil winding 431 and the second coil winding 432 respectively accommodate the two magnetic poles of the magnetic wheel 41.

[0101] It is worth mentioning that the power generation cavity 42 has a convex partition beam 421, wherein the first coil winding 431 and the second coil winding 432 are wound around the power generation cavity 42 on both sides of the partition beam 421. Initially, the magnetic poles of the magnetic wheel 41 are bounded by the partition beam 421, and the first coil winding 431 and the second coil winding 432 are respectively arranged on both sides of the magnetic wheel 41, which helps to reduce the loss of magnetic energy.

[0102] In particular, the distance between the first coil winding 431 and the second coil winding 432 is less than or equal to the diameter of the magnet wheel 41, which is beneficial to the miniaturization of the rotor generator 40.

[0103] It is worth mentioning that the power generation cavity 42 includes a first half cavity and a second half cavity, wherein the first half cavity and the second half cavity are detachably spliced ​​together. The power generation cavity 42 based on the split splicing design facilitates the assembly of the rotor generator 40 and helps to improve the corresponding production efficiency.

[0104] Specifically, the power generation cavity 42 houses the magnetic wheel 41 in a sealed manner to ensure the reliable operation of the magnetic wheel 41. That is, the power generation cavity 42 is set to be closed to keep the power generation cavity 420 from the influence of external substances, so as to ensure that the magnetic wheel 41 housed in the power generation cavity 420 can operate reliably without the influence of external substances.

[0105] It is worth mentioning that when an operation is completed, the magnetic wheel 41 rotates at high speed in the closed power generation cavity 42, and the coil winding 43 can drive a load with a resistance of 700 ohms to continuously provide 2V voltage for more than 70 milliseconds.

[0106] Specifically, when an operation is completed, the high-speed rotation of the magnetic wheel 41 causes the coil winding 43 to output a pulse voltage. The time from the initial generation of electrical energy to the output of the rated voltage is less than 80 milliseconds. For a more detailed example, please refer to the accompanying drawings of this utility model. Figure 11 As shown, when the pivot drive arm 20 is pressed by approximately 5mm and actuated once, the rotor generator 20 can output 2V of electrical energy within 30ms and generate at least 10 pulses of energy within 100ms. Taking a 700-ohm resistor as an example, with a 2V power supply, the rotor generator 20 can provide continuous energy to the load for at least 100ms with one actuation of the pivot drive arm 20. If the load is a low-power microcontroller (MCU), the rotor generator 20 can provide power for tens of seconds or even one minute with one actuation of the pivot drive arm 20, providing sufficient time for the MCU to complete specific tasks. When the self-generating module can generate multiple continuous pulses of power, the communication circuit 50 can continuously transmit wireless data for a longer period of time to pair and bind with other standard Bluetooth devices, and issue a variable security key to the self-generating module through the gateway.

[0107] In other words, the self-generating module, due to its sufficient energy supply, is significantly superior to existing passive control switches in terms of communication distance, security, and the types of devices it can connect to. It is understood that the "sustainable" aspect of this invention should not be narrowly interpreted as a continuous power supply capability similar to battery power, nor should it be interpreted as a power supply capability similar to a hand-cranked generator.

[0108] It is worth mentioning that, based on the speed-increasing component 30, the speed-increasing amplification of the movement of the pivot drive arm 20 can continuously extend the mechanical energy of pressing the pivot drive arm 20 to the magnetic wheel 41. In a short pressing operation of about 100ms, the speed-increasing extension forms an energy supply time of about 200-900ms, which significantly extends the energy supply time of the rotor generator 40, which is a huge improvement compared to the existing technology that can only achieve an energy supply time of 2 milliseconds.

[0109] Furthermore, based on the speed-increasing component 30 amplifying the speed of the pivot drive arm 20's movement, and the free design of the magnetic wheel 41 within the power generation cavity 42 (i.e., the magnetic wheel 41 is not subject to magnetic attraction), the driving force of the pivot drive arm 20 can be set to less than 10N, which is beneficial for improving the operator's pressing feel.

[0110] Based on the linkage and relationship between the pivot drive arm 20, the speed-increasing component 30, and the rotor generator 40, the rotor generator 40 has high power generation efficiency, which can increase the power supply time by 20 to 100 times compared with the existing passive control switch. Therefore, it can maintain the communication circuit 50 with higher power requirements and / or support the communication circuit 50 to complete long-term operation. Since the energy consumption of various loads is different, in order to measure the power generation capacity of the rotor generator 40, in this embodiment, the equivalent resistance of the communication circuit 50 can be set to 400-700 ohms. Compared with the communication circuit of the current passive control switch, it has higher working energy and can achieve complex operation, so as to support the self-generating module to successfully access the network to achieve the required communication tasks, or support the touch circuit to reliably complete the key detection process, realize multi-key capacitive touch operation under passive conditions, which is of great significance to the upgrading of self-generating products and the development of the self-generating switch field.

[0111] To further understand this utility model, this utility model provides a method for generating electricity using a self-generating module, wherein the method for generating electricity using the self-generating module includes the following steps:

[0112] A. When the pivot drive arm 20 is in a pivoted state, the position change of its contact position drives a speed-increasing component 30 in conjunction with the pivot drive arm 20.

[0113] B. The speed-increasing component 30 amplifies the motion stroke of the pivot drive arm 20 and outputs it to a rotor generator 40;

[0114] C. A magnet 41 of the rotor generator 40 is driven by the speed-increasing component 30 and rotates within a power generation cavity 42 to generate electrical energy with at least one coil winding 43 wound around the power generation cavity 42.

[0115] Specifically, step B includes:

[0116] B1. A push rod 31 of the speed-increasing component 30 is linked by the pivot drive arm 20 to drive an input wheel 321 to rotate.

[0117] B2. The input wheel 321 drives a speed-increasing output wheel 322, which is coaxially arranged with it, to rotate. The diameter of the speed-increasing output wheel 322 is larger than the diameter of the input wheel 321, so that the movement stroke of the pivot drive arm 20 is amplified at one time.

[0118] B3. The speed-increasing output wheel 322 drives an output drive wheel 33 meshing with it to rotate. The transmission ratio between the speed-increasing output wheel 322 and the output drive wheel 33 is less than 1, so that the output drive wheel 33 is driven by the speed-increasing output wheel 322 at an increased speed.

[0119] B4. The output drive wheel 33 drives the magnetic wheel 41, which is coaxially arranged with it, to rotate.

[0120] Preferably, in step B2, if the ratio of the diameter of the speed-increasing output wheel to the diameter of the input wheel is greater than or equal to 5, then when the input wheel 321 is rotated one revolution by the push rod 31, the corresponding stroke is amplified by the speed-increasing wheel set 32 ​​by more than five times. This allows the motion stroke of the push rod 31 to be amplified and output to the output drive wheel 33. Under the same pressing stroke, the drive stroke of the rotor generator 40 is extended. On the one hand, this helps to increase the number of revolutions of the magnetic wheel 41, thereby enhancing the pulse energy output by the rotor generator 40. On the other hand, it helps to accelerate the motion response speed of the rotor generator 40 to the pivot drive arm 20, satisfying the user's habit of pressing and using immediately.

[0121] Preferably, in step B3, the transmission ratio between the speed-increasing output wheel and the output drive wheel is less than or equal to 1 / 4. In this case, when the pivot drive arm 20 is driven, the magnetic wheel 41 can be rotated at high speed in conjunction with the drive arm. This increases the rotational speed of the magnetic wheel 41 to enhance the pulse energy output by the rotor generator 40, and also speeds up the power generation response of the rotor generator 40, thus satisfying the user's habit of using the device immediately upon pressing it.

[0122] Specifically, initially, one side of the oblique surface 210 of the pivot drive arm 20 abuts against the push rod 31. In step A, the push rod 31 moves relative to the oblique surface 210 to the other side of the oblique surface 210, forming a positional change of the abutment position. This causes the speed-increasing wheel set 32 ​​to rotate continuously, thereby driving the output drive wheel 33 to rotate continuously, which in turn causes the magnetic wheel 41 to rotate continuously. This extends the driving time of the rotor generator 40, allowing the actuation time of the pivot drive arm 20 to be continuously transmitted to drive the rotor generator 40, thus maintaining the continuous power generation of the rotor generator 40.

[0123] Furthermore, the self-generating module further includes step D, where a reverse thrust member 34 reverses the push rod 31 to repeat step B, wherein the reverse thrust member 34 is linked with the push rod 31 in step A to accumulate potential energy in order to make full use of mechanical energy, thereby increasing the output energy of the self-generating module and extending the energy output time of the rotor generator 40.

[0124] Furthermore, in step B1, the push rod 31 engages with the input wheel 321 via a push rack 311 to rotate the input wheel 321, wherein the push rack 311 is disposed on the side of the push rod 31 in the radial direction of the push rod 31.

[0125] Furthermore, one end of the push rod 31 is abutted against the chamfered surface 210, and the push rack 311 is close to the other end of the push rod 31, so as to facilitate the structural layout of the self-generating module.

[0126] Furthermore, in step D, the thrust reverser 34 is positioned within a force-guiding cavity 3120 of the push rod 31 and is thus limited. The push rod 31 has a hollow section 312, which is hollowly designed to define the force-guiding cavity 3120. This guides the direction of the force applied by the push rod 31 to the thrust reverser 34 and the direction of the thrust reverser 34's thrust, ensuring a balanced force application by the thrust reverser 34 and thus ensuring the linkage stability of the push rod 31 with the speed-increasing wheel set 34.
