Description

Technical Field

[0001] This invention relates to a self-generating device, and more specifically, to a self-generating module dual-spring trigger mechanism and a self-generating push-button switch. Background Technology

[0002] Self-generating modules, also known as micro-energy push-to-power modules, utilize the principle of electromagnetic induction. By pressing or other means, the direction of magnetic flux is changed, generating an electromotive force in the coil, which in turn induces a current in a closed circuit. Currently, they are widely used in some wireless control switches or devices, such as wireless push-to-power doorbell buttons, wireless light switches, remote controls, and wireless keyboards. They generate current by pressing to send control signals, eliminating the need for battery power.

[0003] Existing self-generating modules mainly consist of two parts: a coil and a magnetic circuit. The magnetic circuit typically comprises a permanent magnet, a magnetic guide frame, and a switching lever. The coil is wound around the magnetic circuit, and the switching lever changes the direction of the magnetic flux, inducing a current in the coil. During the switching of the magnetic flux direction, the switching speed directly affects the power generation efficiency and current intensity. Therefore, most existing self-generating modules employ a spring-loaded design on the lever, utilizing the deformation of the spring during pressing to store energy. This allows the lever to switch quickly when the switching threshold is reached, thanks to the spring's elasticity.

[0004] However, existing self-generating modules all use a single spring design. To ensure good elasticity, the spring itself is very thin. The pressing stroke required to deform the spring and switch the spring force is relatively large, which seriously affects the user experience. In addition, the spring needs to cooperate with a pressing component or transmission component to bend and deform it. A small hole with a height greater than the thickness of the spring needs to be set on the pressing component or transmission component, and the free end of the spring extends into the small hole. However, because the spring is small and thin, the size of the matching small hole is also very small, which makes it difficult to manufacture. Especially for stamped transmission components, it is difficult to punch the small hole that mates with the spring. If a larger hole is used, a larger pressing stroke is required, which is often counterproductive. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve

[0006] The purpose of this invention is to overcome the shortcomings of existing self-generating module spring trigger mechanisms, such as large travel distance and small spring hole size, which are difficult to process. This invention provides a dual-spring trigger mechanism for self-generating modules and a self-generating push-button switch. The invention employs a dual-spring design, with a gap between the upper and lower springs in the free state. During the pressing of the transmission component, the upper spring bends to store energy, and during the rebound of the transmission component, the lower spring bends to store energy. This reduces the pressing and rebound travel distance of the springs, improves the triggering stability of the self-generating module, and enhances the user experience of self-generating products. Furthermore, the size of the spring hole that mates with the dual springs can be designed to be larger, facilitating the manufacturing of the spring hole.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0009] The present invention provides a self-generating module dual-spring trigger mechanism, comprising a self-generating module, a transmission component, and an elastic component. The self-generating module has a magnetic guide rod, the end of which is provided with a spring. The transmission component has a spring hole, the free end of which extends into the spring hole. The elastic component acts directly or indirectly on the transmission component. The spring includes an upper spring and a lower spring arranged opposite to each other, and there is a gap between the upper spring and the lower spring in the free state.

[0010] During the process of the transmission component being pressed down by a force opposite to the elastic force of the elastic component, the upper hole wall of the spring plate hole pushes the corresponding upper spring plate to bend it, and the lower hole wall of the spring plate hole separates from the lower spring plate.

[0011] During the process of the transmission component rebounding under the elastic force of the elastic element, the lower hole wall of the spring plate hole pushes the corresponding lower spring plate, causing it to bend, and the upper hole wall of the spring plate hole separates from the upper spring plate.

[0012] Furthermore, when the transmission component is pressed down to the critical point of switching the magnetic circuit direction of the magnetic guide lever by a force opposite to the elastic force of the elastic component, the free end of the upper spring plate does not contact the lower spring plate, just contacts it, or contacts it, and forces the lower spring plate to bend in the same direction.

[0013] When the transmission component rebounds to the critical point of switching the magnetic circuit direction of the magnetic guide lever due to the elastic force of the elastic element, the free end of the lower spring plate does not contact the upper spring plate, just contacts it, or contacts it, and forces the upper spring plate to bend in the same direction.

[0014] Furthermore, when the transmission component springs back to its initial position, the magnetic guide lever switches the magnetic circuit direction accordingly. At this time, the upper spring plate does not contact or just contacts the upper hole wall of the spring plate hole.

[0015] When the transmission component is pressed down to the lower limit position, the magnetic guide lever switches the magnetic circuit direction accordingly. At this time, the lower spring plate does not contact or just contacts the lower hole wall of the spring plate hole.

[0016] Furthermore, the width of both the upper and lower spring sheets gradually decreases from the connecting end to the free end.

[0017] Furthermore, the self-generating module also includes a coil holder, an induction coil, a magnetic guide frame, a first permanent magnet, and a second permanent magnet. The coil holder is fixedly connected to the magnetic guide frame. The inner side of the coil holder has a channel through which the magnetic guide lever passes and can rotate in a lever-like manner within the channel. The induction coil is wound on the coil holder, and the magnetic guide lever passes through the inner side of the induction coil. The first permanent magnet and the second permanent magnet are respectively fixed on the magnetic guide frame. When the magnetic guide lever rotates in a lever-like manner, one end of the magnetic guide lever can contact the magnetic guide frame, and the other end can contact the first permanent magnet or the second permanent magnet, forming two closed magnetic circuits with opposite magnetic flux directions on the magnetic guide lever.

[0018] Furthermore, the magnetic guide frame includes a first magnetic guide plate, a second magnetic guide plate, and a rear magnetic guide plate. The front end of the first magnetic guide plate has a first pair of insertion holes and a first pair of horizontally bent insertion arms. The rear end of the first magnetic guide plate has a first magnet mounting portion that is horizontally bent. The front end of the second magnetic guide plate has a second pair of insertion holes and a second pair of horizontally bent insertion arms. The rear end of the second magnetic guide plate has a second magnet mounting portion that is horizontally bent. The first and second magnetic guide plates are interlocked, with the first pair of insertion arms inserted into the second pair of insertion holes and the second pair of insertion arms inserted into the first pair of insertion holes. The first and second magnet mounting portions are joined to form a rectangular magnet mounting frame. The rear magnetic guide plate has horizontally bent connecting plates at the top and bottom. The rear magnetic guide plate is fastened to the rear of the rectangular magnet mounting frame through the horizontal connecting plates. The free ends of the first pair of insertion arms protrude from the sidewall of the second magnetic guide plate as mounting portions, and the free ends of the second pair of insertion arms protrude from the sidewall of the first magnetic guide plate as mounting portions.

[0019] The present invention discloses a self-generating push-button switch, comprising a self-generating module, a transmission component, an elastic component, a base, a button panel, and a circuit board. The self-generating module and the circuit board are fixed inside the base and electrically connected. The transmission component is movably disposed within the base. The elastic component is disposed within the base and acts on the transmission component. The button panel is movably mounted on the base and is directly or indirectly connected to the transmission component. The self-generating module and the transmission component are coupled using the aforementioned self-generating module double-spring trigger mechanism.

[0020] Furthermore, the transmission component is a sheet metal part, and the lower hole wall of the spring hole that connects with the upper surface of the transmission component is an inclined surface that slopes downward toward the self-generating module side.

[0021] Furthermore, the base is provided with a front latch and a rear latch, each consisting of two latches placed on opposite sides. The front latch and the rear latch fix the self-generating module to the base from the side.

[0022] Furthermore, the button panel has at least two buttons, and the circuit board has contact switches corresponding to each button panel. The transmission component spans each button panel and is guided and cooperated with the base, so that each button panel can independently trigger the transmission component to perform a pressing action. The circuit board is also provided with a waterproof soft cover and an intermediate pressure cover in sequence. The intermediate pressure cover is fixed on the base, confining the waterproof soft cover between the intermediate pressure cover and the base.

[0023] 3. Beneficial effects

[0024] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages:

[0025] (1) A self-generating module double-spring triggering mechanism of the present invention includes a self-generating module, a transmission component and an elastic component. The self-generating module has a magnetic guide rod, and the end of the magnetic guide rod is provided with a spring. The transmission component is provided with a spring hole, and the free end of the spring extends into the spring hole. The elastic component acts directly or indirectly on the transmission component. The spring includes an upper spring and a lower spring arranged opposite to each other. There is a gap between the upper spring and the lower spring in the free state. During the process of the transmission component being pressed down, the upper spring is used to bend and store energy. During the process of the transmission component rebounding, the lower spring is used to bend and store energy. This can reduce the spring pressing and rebound stroke, improve the triggering stability of the self-generating module, and improve the user experience of the self-generating product. In addition, the size of the spring hole that cooperates with the double spring can be designed to be larger, which facilitates the manufacturing of the spring hole.

[0026] (2) The self-generating module double spring triggering mechanism of the present invention, in the process of the transmission component being pressed down, the upper spring bends and stores energy, and the lower spring separates from the lower hole wall of the spring hole. In the process of the transmission component rebounding, the lower spring bends and stores energy, and the upper spring separates from the upper hole wall of the spring hole. When the magnetic guide rod reaches the critical point of magnetic circuit direction switching, the double spring can quickly release the elastic force and instantly complete the magnetic circuit switching, thereby improving the power generation efficiency and current intensity.

[0027] (3) The self-generating module double spring triggering mechanism of the present invention can use either single spring bending energy storage or double spring bending energy storage when the transmission component is pressed down to the critical point of magnetic circuit direction switching of the magnetic guide lever or when the transmission component rebounds to the critical point of magnetic circuit direction switching of the magnetic guide lever. The single spring bending energy storage design makes the structure design simpler and the pressing and rebound strokes can be designed to be smaller; the double spring bending energy storage design allows the combined elastic force of the springs to be designed to be greater, making the magnetic circuit switching action faster and more stable.

[0028] (4) In the self-generating module double spring triggering mechanism of the present invention, when the transmission component rebounds to the initial position, the magnetic guide rod switches the magnetic circuit direction accordingly. At this time, the upper spring does not contact or just contacts the upper hole wall of the spring hole; when the transmission component is pressed down to the lower limit position, the magnetic guide rod switches the magnetic circuit direction accordingly. At this time, the lower spring does not contact or just contacts the lower hole wall of the spring hole. With this design, while ensuring that the pressing and rebound strokes are small enough, it can prevent the spring from colliding with the spring hole, which would reduce the magnetic circuit switching speed and stability, and effectively ensure that the spring bounces quickly.

[0029] (5) The self-generating module double spring triggering mechanism of the present invention has a width of upper spring and lower spring that gradually decreases from the connecting end to the free end, which makes the elastic deformation capability of the free end of the spring stronger, and can better exert the instantaneous spring effect of the spring, further improving the magnetic circuit switching speed and reliability.

[0030] (6) A self-generating module double spring triggering mechanism of the present invention, wherein the self-generating module further includes a coil holder, an induction coil, a magnetic guide frame, a first permanent magnet and a second permanent magnet. When the magnetic guide lever rotates in a lever-like manner, one end of the magnetic guide lever can contact the magnetic guide frame, and the other end can contact the first permanent magnet or the second permanent magnet, forming two closed magnetic circuits with opposite magnetic flux directions on the magnetic guide lever. The self-generating module has a compact and small structure, a simple structure, and stable and efficient self-generating power.

[0031] (7) A self-generating module dual-spring triggering mechanism of the present invention has a magnetic guide frame including a first magnetic guide plate, a second magnetic guide plate and a rear magnetic guide plate. The magnetic guide frame is assembled from the above three magnetic guide plates, which makes the magnetic guide frame simple and convenient to manufacture and facilitates the assembly and manufacturing of the self-generating module. In addition, in the magnetic guide frame, the free ends of the first pair of plug arms protrude from the side wall of the second magnetic guide plate as mounting parts, and the free ends of the second pair of plug arms protrude from the side wall of the first magnetic guide plate as mounting parts, which adds a snap-fit ​​fixing point for the self-generating module and facilitates the installation of the self-generating module in the product.

[0032] (8) A self-generating push button switch of the present invention includes a self-generating module, a transmission component, an elastic component, a base, a button panel and a circuit board. The self-generating module and the transmission component are cooperated by the above-mentioned self-generating module double spring triggering mechanism, so that the self-generating push button switch has a smaller pressing stroke and better pressing rebound feedback, further improving the feel of the self-generating push button switch.

[0033] (9) A self-generating push button switch of the present invention has a transmission component made of sheet metal. The lower hole wall that connects the spring hole and the upper surface of the transmission component is a slope that slopes downward toward the self-generating module. The transmission component is manufactured using sheet metal technology, which results in high structural strength and simple and convenient manufacturing. Furthermore, the sloped design of the lower hole wall can avoid the lower spring, ensuring that the spring can be bent under force at the free end, thus preventing interference with the lower spring and affecting the performance of the spring.

[0034] (10) A self-generating push button switch of the present invention has a base with a front buckle and a rear buckle. The front buckle and the rear buckle are each composed of two buckles placed on both sides and opposite to each other. The front buckle and the rear buckle fix the self-generating module in the base from the side of the self-generating module, making the installation and operation of the self-generating module in the base simpler and more convenient.

[0035] (11) The present invention provides a self-generating push button switch, which has at least two push button panels and a circuit board with contact switches corresponding to each push button panel. This allows multiple independently controlled push buttons to be formed on one switch, improving the practicality of the switch. Furthermore, the switch has a simple and compact structure, is waterproof, does not require battery power, and has a longer service life. Attached Figure Description

Detailed Implementation

[0049] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0050] Combination Figure 1 , Figures 2(a) to 2(d)As shown, the self-generating module dual-spring trigger mechanism of the present invention includes a self-generating module 1, a transmission component 2, and an elastic component 3. The transmission component 2 is used to change the magnetic circuit of the self-generating module 1, and the elastic component 3 is used to reset the self-generating module 1. The self-generating module 1 has a magnetic guide rod 1-1, and the end of the magnetic guide rod 1-1 is provided with a spring. The transmission component 2 is provided with a spring hole 2-1, and the free end of the spring extends into the spring hole 2-1. The elastic component 3 acts directly or indirectly on the transmission component 2. The action of the transmission component 2 can be transmitted to the magnetic guide rod 1-1 through the spring, causing the magnetic guide rod 1-1 to switch the magnetic circuit direction, thereby generating an induced current. Unlike existing self-generating trigger mechanisms, the present invention adopts a dual-spring design, that is, the spring includes an upper spring 1-2 and a lower spring 1-3 arranged opposite to each other, and there is a gap between the upper spring 1-2 and the lower spring 1-3 in the free state. During the process of the transmission component 2 being pressed down by the opposite force to the elastic force of the elastic component 3, the upper hole wall 2-1-1 of the spring plate hole 2-1 pushes the corresponding upper spring plate 1-2 to bend it. At this time, the lower hole wall 2-1-2 of the spring plate hole 2-1 separates from the lower spring plate 1-3 (as shown in Figure 2(b)). As the deformation of the upper spring plate 1-2 increases, the bending elastic potential energy of the upper spring plate 1-2 increases. When the critical point of magnetic circuit switching is reached, the upper spring plate 1-2 rebounds, causing the magnetic guide lever 1-1 to swing rapidly to switch the direction of the magnetic circuit (as shown in Figure 2(c)). Since the lower hole wall 2-1-2 and the lower spring plate 1-3 are in a separated state before the rebound action occurs, both the upper spring plate 1-2 and the lower spring plate 1-3 have rebound motion space. Conversely, during the rebound of the transmission component 2 by the elastic force of the elastic component 3, the lower hole wall 2-1-2 of the spring plate hole 2-1 pushes the corresponding lower spring plate 1-3 to bend it. At this time, the upper hole wall 2-1-1 of the spring plate hole 2-1 separates from the upper spring plate 1-2 (as shown in Figure 2(d)). As the deformation of the lower spring plate 1-3 increases, the bending elastic potential energy of the lower spring plate 1-3 increases. When the critical point of magnetic circuit switching is reached, the lower spring plate 1-3 rebounds, causing the magnetic guide lever 1-1 to swing rapidly to switch the direction of the magnetic circuit (as shown in Figure 2(a)). Since the upper hole wall 2-1-1 and the upper spring plate 1-2 are in a separated state before the rebound action occurs, both the upper spring plate 1-2 and the lower spring plate 1-3 have rebound motion space. It should be understood that the position of the upper and lower springs bending to reach the critical point of magnetic circuit switching depends on the magnetic attraction between the magnetic guide rod 1-1 and the permanent magnet in the self-generating module 1. When the elastic potential energy of the springs bending overcomes the magnetic attraction of the permanent magnet on the magnetic guide rod 1-1, the magnetic guide rod 1-1 will rotate to switch the direction of magnetic circuit conduction, thereby forming an induced current.

[0051] Based on the above-mentioned dual-spring design, during the pressing and rebounding processes, the two springs cooperate with the transmission component 2. The transmission component 2 only needs to press down or rebound a small distance to control the swing of the magnetic lever 1-1 using the springs, thereby reducing the pressing and rebounding stroke of the self-generating module, improving the triggering stability of the self-generating module, and improving the user experience of the self-generating product. Furthermore, the size of the spring hole that cooperates with the dual springs can be designed to be larger, which facilitates the manufacturing of the spring hole. Especially for stamping, the size of the punch can be designed to be larger, making it less prone to breakage.

[0052] The present invention will be further described below with reference to embodiments.

[0053] [Example 1]

[0054] like Figure 1 , Figures 2(a) to 2(d)As shown, this embodiment of a self-generating module dual-spring trigger mechanism includes a self-generating module 1, a transmission component 2, and an elastic component 3. The self-generating module 1 has a magnetic guide rod 1-1. The direction of the magnetic circuit within the self-generating module 1 is switched by the swing of the magnetic guide rod 1-1, thereby generating an induced current. The end of the magnetic guide rod 1-1 is provided with a spring piece. The transmission component 2 is provided with a spring piece hole 2-1. The free end of the spring piece extends into the spring piece hole 2-1. The movement of the transmission component 2 can be transmitted to the magnetic guide rod 1-1 through the spring piece. The elastic component 3 acts directly or indirectly on the transmission component 2, providing elastic force for the reset of the transmission component 2. In this embodiment, the spring pieces include an upper spring piece 1-2 and a lower spring piece 1-3 arranged opposite to each other. Both the upper spring piece 1-2 and the lower spring piece 1-3 can be made of thin metal plates and can be fixed to the magnetic guide rod 1-1 by riveting. There is a gap between the upper spring piece 1-2 and the lower spring piece 1-3 in the free state. For ease of installation, the upper spring piece 1-2 and the lower spring piece 1-3 can be placed on opposite sides of the magnetic guide rod 1-1. In this case, the free-state gap between the upper spring piece 1-2 and the lower spring piece 1-3 is approximately equal to the thickness of the magnetic guide rod 1-1. The distance between the upper hole wall 2-1-1 and the lower hole wall 2-1-2 of the spring piece hole 2-1 is roughly equivalent to the distance between the outer walls of the upper spring piece 1-2 and the lower spring piece 1-3 in their free state; it can be slightly larger or smaller. As shown in Figure 2(b), during the process of the transmission component 2 being pressed down by the opposite force to the elastic force of the elastic component 3 (such as a pressing action), the upper hole wall 2-1-1 of the spring hole 2-1 pushes the corresponding upper spring 1-2 to bend it, and the lower hole wall 2-1-2 of the spring hole 2-1 separates from the lower spring 1-3. After the upper spring 1-2 bends to a certain extent, it overcomes the swing magnetic attraction of the magnetic guide rod 1-1. At this time, the upper spring 1-2 rebounds, causing the magnetic guide rod 1-1 to swing rapidly to the state shown in Figure 2(c). As shown in Figure 2(d), after the pressing action is released, the transmission component 2 is only subjected to the elastic force of the elastic component 3. During the rebound process of the transmission component 2 under the elastic force of the elastic component 3, the lower hole wall 2-1-2 of the spring hole 2-1 pushes the corresponding lower spring 1-3 to bend it. The upper hole wall 2-1-1 of the spring hole 2-1 separates from the upper spring 1-2. After the lower spring 1-3 bends to a certain extent, it overcomes the swing magnetic attraction of the magnetic guide rod 1-1. At this time, the lower spring 1-3 rebounds, causing the magnetic guide rod 1-1 to swing rapidly to the state shown in Figure 2(a).

[0055] The above-mentioned double-spring design has a gap between the upper and lower springs in the free state. During the pressing of the transmission component 2, the upper spring 1-2 is used to bend and store energy, and during the rebound of the transmission component 2, the lower spring 1-3 is used to bend and store energy. This reduces the pressing and rebound stroke of the springs, improves the triggering stability of the self-generating module, and improves the user experience of the self-generating product. In addition, the size of the spring hole 2-1 that cooperates with the double springs can be designed to be larger, which facilitates the manufacturing of the spring hole.

[0056] Furthermore, when the transmission component 2 is pressed down to the critical point of magnetic circuit direction switching of the magnetic guide lever 1-1 by the opposite force to the elastic force of the elastic component 3 (as shown in Figure 2(b)), the free end of the upper spring piece 1-2 is not in contact with or is just in contact with the lower spring piece 1-3. When the transmission component 2 is rebounded to the critical point of magnetic circuit direction switching of the magnetic guide lever 1-1 by the elastic force of the elastic component 3 (as shown in Figure 2(d)), the free end of the lower spring piece 1-3 is not in contact with or is just in contact with the upper spring piece 1-2. At this time, only the bending energy storage of a single spring piece is used, the structural design is simpler, and the pressing and rebound strokes can be designed to be smaller. Moreover, when the magnetic guide lever 1-1 reaches the critical point of magnetic circuit direction switching, there is a gap between the unbent and deformed spring piece and the corresponding hole wall. At this time, the bent and deformed spring piece can quickly release the elastic force and instantly complete the magnetic circuit switching, which is beneficial to improving power generation efficiency and current intensity.

[0057] Furthermore, in this embodiment, when the transmission component 2 springs back to its initial position, the magnetic guide lever 1-1 switches the magnetic circuit direction accordingly, as shown in Figure 2(a). At this time, the upper spring piece 1-2 is not in contact with or is just in contact with the upper hole wall 2-1-1 of the spring piece hole 2-1. When the transmission component 2 is pressed down to the lower limit position, the magnetic guide lever 1-1 switches the magnetic circuit direction accordingly, as shown in Figure 2(c). At this time, the lower spring piece 1-3 is not in contact with or is just in contact with the lower hole wall 2-1-2 of the spring piece hole 2-1. With the above design, while ensuring that the pressing and rebound strokes are sufficiently small, it can prevent the spring piece from colliding with the spring piece hole 2-1, which would reduce the magnetic circuit switching speed and stability, and effectively ensure the rapid spring movement. More preferably, the widths of both the upper spring piece 1-2 and the lower spring piece 1-3 gradually decrease from the connecting end to the free end, making the elastic deformation capability of the free end of the spring piece stronger, better utilizing the instantaneous spring movement effect of the spring piece, and further improving the magnetic circuit switching speed and reliability.

[0058] This embodiment provides a dual-spring-trigger mechanism for a self-generating module, which can be applied to various self-generating modules using spring triggering, thereby reducing the trigger stroke of the self-generating module. This embodiment further provides a specific structure of a self-generating module 1, as follows: Figures 2(a) to 2(d)As shown, the self-generating module 1 also includes a coil holder 1-4, an induction coil 1-5, a magnetic guide frame 1-6, a first permanent magnet 1-7, and a second permanent magnet 1-8. The coil holder 1-4 is fixedly connected to the magnetic guide frame 1-6. The coil holder 1-4 can be made of non-magnetic insulating material, such as an injection molded part. The inner side of the coil holder 1-4 has a channel through which the magnetic guide lever 1-1 passes and can rotate in a lever-like manner within the channel. To facilitate the rotation of the magnetic guide lever 1-1, a fulcrum structure can be set on the upper and lower inner walls in the middle of the channel. The magnetic guide lever 1-1 is supported in the channel by the upper and lower fulcrums and can swing flexibly on the fulcrums. An induction coil 1-5 is wound around a coil holder 1-4, and a magnetic guide lever 1-1 passes through the inside of the induction coil 1-5. A first permanent magnet 1-7 and a second permanent magnet 1-8 are respectively fixed to a magnetic guide frame 1-6. When the magnetic guide lever 1-1 rotates in a lever-like manner, one end of the lever 1-1 can contact the magnetic guide frame 1-6, and the other end can contact either the first permanent magnet 7 or the second permanent magnet 8, forming two closed magnetic circuits with opposite magnetic flux directions on the magnetic guide lever 1-1. In this embodiment, the first permanent magnet 1-7 and the second permanent magnet 1-8 are arranged opposite each other, with their opposite magnetic poles facing each other. One end of the magnetic guide lever 1-1 is located between the first permanent magnet 1-7 and the second permanent magnet 1-8, and the other end passes through the channel of the coil holder 1-4 and is movably engaged with the magnetic guide frame 1-6. The first permanent magnet 1-7 and the second permanent magnet 1-8 are preferably in surface contact with the magnetic guide rod 1-1. This increases the contact area between the magnetic guide rod 1-1 and the permanent magnet poles, ensuring sufficient magnetic flux density through the magnetic guide rod 1-1 and further improving the power generation efficiency and current intensity of the self-generating device. Specifically, the first permanent magnet 1-7 and the second permanent magnet 1-8 can be tilted or designed as trapezoidal structures, so that the opposite magnetic poles of the first permanent magnet 1-7 and the second permanent magnet 1-8 are both inclined planes, and the tilt angle of the inclined planes is the same as the tilt angle of the magnetic guide rod 1-1 when rotated to the corresponding limit position. This ensures surface contact between the magnetic guide rod 1-1 and the permanent magnet. The self-generating module 1 described above has the advantages of being compact, simple in structure, and providing stable and efficient self-generating power.

[0059] like Figure 3 and Figure 4As shown, to facilitate the fabrication of the magnetic guide frame 1-6, in this embodiment, the magnetic guide frame 1-6 includes a first magnetic guide plate 1-6-1, a second magnetic guide plate 1-6-2, and a rear magnetic guide plate 1-6-3. The first magnetic guide plate 1-6-1, the second magnetic guide plate 1-6-2, and the rear magnetic guide plate 1-6-3 are all integral sheet metal parts. The front end of the first magnetic guide plate 1-6-1 has a first pair of insertion holes 1-6-1b and a horizontally bent first pair of insertion arms 1-6-1a. The rear end of the first magnetic guide plate 1-6-1 has a horizontally bent first magnet mounting portion 1-6-1c. The front end of the second magnetic guide plate 1-6-2 has a second pair of insertion holes 1-6-2b and a horizontally bent second pair of insertion arms 1-6-1a. 2a. The rear end of the second magnetic plate 1-6-2 has a horizontally bent second magnet mounting part 1-6-2c. The first magnetic plate 1-6-1 and the second magnetic plate 1-6-2 are interlocked, so that the first pair of insertion arms 1-6-1a are inserted into the second pair of insertion holes 1-6-2b, and the second pair of insertion arms 1-6-2a are inserted into the first pair of insertion holes 1-6-1b. The first magnet mounting part 1-6-1c and the second magnet mounting part 1-6-2c are joined to form a rectangular magnet mounting frame. The rear magnetic plate 1-6-3 has horizontally bent horizontal connecting plates 1-6-3a at the top and bottom, and the rear magnetic plate 1-6-3 is fastened to the rear of the rectangular magnet mounting frame through the horizontal connecting plates 1-6-3a. The magnetic frame 1-6 is assembled from the above three magnetic plates, making the magnetic frame 1-6 simple and convenient to manufacture, and facilitating the assembly and manufacturing of the self-generating module. The first magnet mounting portion 1-6-1c and the second magnet mounting portion 1-6-2c described above preferably adopt a U-shaped structure with opposite openings, so that the splicing seam between the two is located in the middle. The first permanent magnet 1-7 and the second permanent magnet 1-8 are respectively installed in the rectangular magnet mounting frame formed by the first magnet mounting portion 1-6-1c and the second magnet mounting portion 1-6-2c, which is beneficial to improving the magnetic conductivity of the magnetic guide frame 1-6. Furthermore, the free ends of the first pair of insert arms 1-6-1a protrude from the side wall of the second magnetic guide plate 1-6-2 as mounting portions, and the free ends of the second pair of insert arms 1-6-2a protrude from the side wall of the first magnetic guide plate 1-6-1 as mounting portions, which adds snap-fit ​​fixing points for the self-generating module 1, facilitating the installation of the self-generating module in the product.

[0060] This embodiment presents a self-generating module dual-spring trigger mechanism, which can be used in various push-button self-generating products, such as wireless push-button doorbells, wirelessly controlled light switches, remote controls, and wireless keyboards. Figures 5 to 8As shown, this embodiment also discloses a self-generating push button switch, which includes a self-generating module 1, a transmission component 2, an elastic component 3, a base 4, a button panel 5, and a circuit board 6. The self-generating module 1 and the circuit board 6 are fixed inside the base 4 and are electrically connected. The transmission component 2 is movably disposed inside the base 4, and the elastic component 3 is disposed inside the base 4 and acts on the transmission component 2. The button panel 5 is movably mounted on the base 4 and is directly or indirectly connected to the transmission component 2. The self-generating module 1 and the transmission component 2 are cooperated by the aforementioned self-generating module double spring trigger mechanism, so that the self-generating push button switch has a smaller pressing stroke and better pressing rebound feedback, further improving the feel of the self-generating push button switch.

[0061] See Figure 1 , Figures 2(a) to 2(d) As shown, in this embodiment, the transmission component 2 is a sheet metal part, and the spring hole 2-1 can be manufactured using bending and punching processes. The transmission component has high structural strength and is simple and convenient to manufacture. Since the lower hole wall 2-1-2 of the spring hole 2-1 is connected to the horizontal part of the transmission component 2, in order to prevent the horizontal part of the transmission component 2 from interfering with the lower spring 1-3, preferably, the lower hole wall 2-1-2 that connects the spring hole 2-1 to the upper surface of the transmission component 2 is a sloped surface inclined downward toward the self-generating module 1. By adopting a sloped design for the lower hole wall 2-1-2, the lower spring 1-3 can be avoided, ensuring that the spring can be bent under force at the free end, preventing interference with the lower spring 1-3 and affecting the performance of the spring. The aforementioned elastic component 3 is preferably a torsion spring, which is installed in the base 4, with one elastic arm resting in the base 4 and the other elastic arm resting on the transmission component 2.

[0062] like Figure 7 and Figure 8 As shown, in this embodiment, the base 4 is provided with a front latch 4-3 and a rear latch 4-4 inside. Both the front latch 4-3 and the rear latch 4-4 consist of two latches positioned on opposite sides. The front latch 4-3 and the rear latch 4-4 fix the self-generating module 1 to the base 4 from the side. Specifically, the two front latches 4-3 are respectively latched onto the protrusions of the two interlocking arms of the magnetic guide frame 1-6 of the self-generating module 1, and the two rear latches 4-4 are respectively latched onto the rear end side wall of the magnetic guide frame 1-6 of the self-generating module 1. This way, only the side latches are needed to fix the self-generating module 1, making the installation of the self-generating module inside the base simpler and more convenient. Furthermore, the base 4 is also provided with limiting baffles 4-2 located on both sides of the self-generating module 1, and corresponding limiting bosses are also provided at the front and rear ends of the self-generating module 1 for limiting its position. A torsion spring seat is provided in the base 4 at the position opposite to the spring of the self-generating module 1. Torsion spring mounting posts 4-6 are provided on both sides of the torsion spring seat, and the torsion spring is mounted on the torsion spring mounting posts 4-6.

[0063] This embodiment of a self-generating push-button switch has at least two push-button panels 5, such as... Figure 5 The circuit board 6 has three button panels 5, and corresponding contact switches 6-1 on each button panel 5. When a button panel 5 is pressed, the corresponding contact switch 6-1 is simultaneously pressed, thus sending a signal that the button panel 5 has been pressed, allowing each button panel 5 to be controlled independently. The aforementioned transmission component 2 spans across each button panel 5 and is guided and cooperates with the base 4, allowing each button panel 5 to independently trigger the transmission component 2 to perform a pressing action. That is, when any button panel 5 is pressed, the transmission component 2 can drive the self-generating module 1 to generate electricity, and only one self-generating module 1 is needed to realize all functions. To make the self-generating button switch more compact and flat, the circuit board 6 also has an opening 6-3 corresponding to the position of the self-generating module 1. The self-generating module 1 is located in the opening 6-3 of the circuit board 6, making the self-generating button switch flatter. Guide holes 2-2 are provided on both sides of the transmission component 2, and guide posts 4-1 corresponding to the guide holes 2-2 are provided in the base 4. The transmission component 2 slides through the guide holes 2-2 and the guide posts 4-1, making the up-and-down movement of the transmission component 2 more stable. In addition, a limit buckle 4-5 is provided on the base 4. The limit buckle 4-5 is located on one side of the transmission component 2 and can limit the upward stroke stop of the transmission component 2. The circuit board 6 is also provided with a micro-encoded switch 6-2 and other electronic components. The circuit principle of the self-generating push button switch is the same as that of the prior art, so the specific circuit combination and principle of the self-generating push button switch will not be described in detail here. In addition, a waterproof soft cover 7 and an intermediate pressure cover 8 are sequentially provided on the circuit board 6. The waterproof soft cover 7 can be made of soft silicone. The intermediate pressure cover 8 is fixed on the base 4, restricting the waterproof soft cover 7 between the intermediate pressure cover 8 and the base 4, which can play a waterproof role, does not require battery power, and has a longer service life.

[0064] [Example 2]

[0065] The self-generating module dual-spring triggering mechanism and self-generating push-button switch of this embodiment have the same basic structure and working principle as in Embodiment 1, except that:

[0066] In this embodiment, when the transmission component 2 is pressed down to the critical point of magnetic circuit direction switching of the magnetic guide lever 1-1 by the opposite force to the elastic force of the elastic component 3 (as shown in Figure 2(b)), the free end of the upper spring piece 1-2 contacts the lower spring piece 1-3 and forces the lower spring piece 1-3 to bend in the same direction; when the transmission component 2 rebounds to the critical point of magnetic circuit direction switching of the magnetic guide lever 1-1 by the elastic force of the elastic component 3 (as shown in Figure 2(d)), the free end of the lower spring piece 1-3 contacts the upper spring piece 1-2 and forces the upper spring piece 1-2 to bend in the same direction. At this time, both the upper spring piece 1-2 and the lower spring piece 1-3 bend and store energy during the pressing or rebounding process, and jointly play a rebounding role. The combined elastic force of the spring pieces can be designed to be larger, making the magnetic circuit switching action faster and more stable.

[0067] This invention discloses a dual-spring trigger mechanism for a self-generating module and a self-generating push-button switch. The trigger mechanism employs a dual-spring design, with a gap between the upper and lower springs in their free state. During the pressing of the transmission component, the upper spring bends to store energy, and during the rebound of the transmission component, the lower spring bends to store energy. This reduces the pressing and rebound strokes of the springs, improves the triggering stability of the self-generating module, and enhances the user experience of the self-generating product. Furthermore, the size of the spring hole that mates with the dual springs can be designed to be larger, facilitating the manufacturing of the spring hole. The self-generating push-button switch, with its dual-spring trigger mechanism design, features a shorter pressing stroke and better pressing and rebound feedback, further improving the tactile feel of the self-generating push-button switch. It also optimizes the structure of the transmission component and the snap-fit ​​connection structure of the self-generating module within the base, resulting in more stable product performance and facilitating the assembly and manufacturing of the self-generating push-button switch.

[0068] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
