Description

Technical Field

[0001] This utility model relates to a self-generating switch, and more specifically, to a self-generating switch with a double-sided pressing structure and a self-generating wireless switch. Background Technology

[0002] The self-generating wireless switch works by converting kinetic energy into electrical energy to achieve wireless control, and has broad application prospects in smart homes, industrial automation, and energy conservation and environmental protection. The self-generating wireless switch mainly consists of two core parts: an energy conversion module and a wireless communication module. The energy conversion module is primarily a miniature generator composed of coils, magnets, magnetic plates, and spring contacts. When the switch is triggered, the internal pressing structure drives the spring contacts to switch the magnetic circuit of the energy conversion module, thereby generating an induced current in the coil, which is then used by the wireless communication module.

[0003] For self-generating switches with multiple buttons and only one internal micro-generator, most have an internal linkage pressing device. This allows the micro-generator to be driven to generate electricity when any button is pressed. Examples include a self-generating wireless switch (patent publication number CN205159138U), a self-generating wireless switch (patent publication number CN211578614U), and a lever-driven self-generating device (patent publication number CN214959234U). These self-generating switches can achieve multi-button and single-micro-generator pressing transmission, enabling multi-switch control. However, these existing self-generating switches share the following common drawbacks:

[0004] Because the micro generator has button drive rods on both sides, and the two button drive rods are connected together by the spring of the micro generator (as in patent applications CN205159138U and CN214959234U) or linked by a lever structure (as in patent application CN211578614U), this linked pressing device design will cause the button drive rod on one side to move when it is pressed. The passively moving button drive rod will generate a certain resistance to the movement of the spring of the micro generator. This resistance is unfavorable, as it will affect the tactile feel of the switch button and the rebound speed of the spring, thus reducing the power generation. Summary of the Invention

[0005] 1. Technical problem to be solved by the utility model

[0006] The purpose of this invention is to overcome the aforementioned shortcomings of existing multi-button self-generating switches and to provide a double-sided pressing structure for a self-generating switch and a self-generating wireless switch. Using the technical solution of this invention, two transmission levers independently and unidirectionally press the spring of the micro-generator, and an elastic reset component provides a rebound force to the spring. This ensures that when one transmission lever is pressed, the other transmission lever remains stationary, thus not affecting the rapid rebound of the micro-generator's spring, guaranteeing the power output of the micro-generator and the operational stability of the switch, while also improving the tactile feedback of the switch buttons.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] This utility model discloses a double-sided pressing structure for a self-generating switch, comprising a micro generator, transmission levers, and an elastic reset component. One end of the micro generator has a spring for transmitting kinetic energy. Each side of the micro generator is provided with a transmission lever capable of pressing and swinging. Both transmission levers have swing arms capable of driving the springs. Wherein:

[0010] Both of the transmission rocker arms have a spring pressing part at their distal ends that can press the spring sheet unidirectionally to the same side. The elastic reset member acts on the spring sheet and applies an elastic force to the spring sheet in the opposite direction to the pressing direction of the spring sheet pressing part.

[0011] Furthermore, the two transmission swing arms are respectively rotatably arranged on both sides of the micro generator, and the swing arms of the two transmission swing arms are respectively extended inward from the rotation axis of their respective transmission swing arms.

[0012] Furthermore, the transmission swing arm has a U-shaped structure consisting of a pressing part and rotating arms at both ends of the pressing part. A first pivot is provided on one end of the rotating arm of the transmission swing arm, and a second pivot coaxial with the first pivot is provided on the other end of the rotating arm. The swing arm is arranged on the corresponding rotating arm facing away from the pressing part.

[0013] Furthermore, the elastic reset element is a torsion spring acting on the spring sheet.

[0014] The present invention provides a self-generating wireless switch having the aforementioned double-sided pressing structure.

[0015] Furthermore, the micro generator and the elastic reset component are respectively mounted on the base, the transmission swing arm is rotatably mounted on the base, and the base is also fixedly provided with an upper cover. The upper cover is equipped with a switch button that cooperates with the transmission swing arm. When the switch button is pressed, the corresponding side of the transmission swing arm drives the spring to move, and when the switch button is released, the elastic reset component drives the spring to spring back to reset, so as to drive the micro generator to generate electrical energy.

[0016] Furthermore, a circuit board is provided between the top cover and the micro generator, and the top cover is also provided with a spring button corresponding to the detection switch on the circuit board. When the switch button is pressed, the corresponding detection switch is triggered by the corresponding spring button.

[0017] Furthermore, the upper cover is also provided with a button mounting shaft for mounting the switch button.

[0018] 3. Beneficial effects

[0019] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0020] (1) The present invention provides a self-generating switch with a double-sided pressing structure and a self-generating wireless switch. The double-sided pressing structure includes a micro generator, a transmission lever, and an elastic reset component. One end of the micro generator has a spring for transmitting kinetic energy. Each side of the micro generator is provided with a transmission lever that can be pressed and swung. Both transmission levers have a swing arm that can drive the spring to move. The far end of the swing arm of both transmission levers has a spring pressing part that can press the spring in one direction to the same side. The elastic reset component acts on the spring and applies an elastic force to the spring in the opposite direction to the pressing direction of the spring pressing part. By using the two transmission levers to independently and unidirectionally press the spring of the micro generator and by using the elastic reset component to provide a rebound force to the spring, when one side of the transmission lever is pressed, the other side of the transmission lever does not move. Therefore, it will not affect the rapid rebound of the spring of the micro generator, ensuring the power generation of the micro generator and the working stability of the switch, and also improving the operation feel of the switch button.

[0021] (2) The present invention provides a self-generating switch with a double-sided pressing structure and a self-generating wireless switch. The two transmission swing arms are respectively rotatably arranged on both sides of the micro generator, and the swing arms of the two transmission swing arms are respectively extended inward from the rotation shaft of their respective transmission swing arms. Thus, the transmission swing arms can drive the spring of the micro generator with a more appropriate pressing force by using the rotation shaft as the fulcrum and lever action, thereby ensuring the feel of the self-generating switch pressing operation.

[0022] (3) The present invention provides a self-generating switch with a double-sided pressing structure and a self-generating wireless switch. The transmission swing arm is a "U"-shaped structure composed of a pressing part and rotating arms at both ends of the pressing part. A first pivot is provided on one end of the rotating arm of the transmission swing arm, and a second pivot coaxial with the first pivot is provided on the other end of the rotating arm. The swing arm is set on the corresponding rotating arm facing away from the pressing part. The two "U"-shaped transmission swing arms can form a space in the middle that is convenient for the installation of a micro generator, which makes the structure of the self-generating switch more compact and the thickness of the self-generating switch made is smaller.

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0034] [Example 1]

[0035] Combination Figure 1 , Figures 3 to 7 As shown, a self-generating switch double-sided pressing structure of this embodiment includes a micro generator 1, a transmission swing arm 2, and an elastic reset member 3. One end of the micro generator 1 has a spring piece 1-1 for transmitting kinetic energy. By switching the spring piece 1-1, the direction of the magnetic circuit inside the micro generator 1 can be changed, thereby generating electrical energy in the induction coil. Each side of the micro generator 1 is provided with a transmission swing arm 2 that can be pressed and swung. Both transmission swing arms 2 have swing arms 2-3 that can drive the spring piece 1-1 to move. That is, the micro generator 1 can be driven to move by the transmission swing arm 2. Both transmission levers 2 and 2 have distal ends of their arms 2-3 that can press the spring piece 1-1 unidirectionally to the same side. That is, the spring piece pressing part 2-4 can only move the spring piece 1-1 to one side, and when the spring piece 1-1 is moved, it will not cause the transmission lever 2 on the other side to move. The elastic reset member 3 acts on the spring piece 1-1 and applies an elastic force to the spring piece 1-1 in the opposite direction to the pressing direction of the spring piece pressing part 2-4, so that the spring piece 1-1 can quickly rebound after being pressed and released. Compared with the existing double-sided linkage design, when one transmission lever 2 is pressed, the other transmission lever 2 remains stationary (e.g., ...). Figure 6 As shown in the figure, this will not affect the rapid rebound of the spring 1-1 of the micro generator 1, ensuring the power generation of the micro generator 1 and the working stability of the switch, and also improving the tactile feel of the switch button.

[0036] Reference Figures 1 to 6 As shown, two transmission levers 2 are respectively rotatably mounted on both sides of the micro generator 1, and the swing arms 2-3 of the two transmission levers 2 extend inward from their respective rotation axes. This allows the transmission levers 2 to drive the spring 1-1 of the micro generator 1 with a more suitable pressing force, using the rotation axis as a fulcrum and lever action, thus ensuring a tactile feedback during the self-generating switch pressing operation. Specifically, the pressing force can be adjusted by adjusting the length of the lever arms on both sides of the rotation axis of the transmission lever 2. In this embodiment, the transmission lever 2 has a U-shaped structure consisting of a pressing part 2a and rotating arms 2b located at both ends of the pressing part 2a (see reference). Figure 8As shown, a first pivot 2-1 is provided on one end of the rotating arm 2b of the transmission lever 2, and a second pivot 2-2 coaxial with the first pivot 2-1 is provided on the other end of the rotating arm 2b. The first pivot 2-1 and the second pivot 2-2 form the rotation axis of the transmission lever 2. The transmission lever 2 can be rotatably mounted on the base of the switch via the first pivot 2-1 and the second pivot 2-2. The swing arm 2-3 is provided on the corresponding rotating arm 2b facing away from the pressing part 2a. The two U-shaped transmission levers 2 can form a space in the middle that facilitates the installation of the micro generator 1, making the structure of the self-generating switch more compact and the thickness of the self-generating switch smaller. The aforementioned spring pressing part 2-4 can be provided with a step for contacting the spring 1-1. Preferably, the elastic reset member 3 is a torsion spring acting on the spring 1-1. The torsion spring can be mounted on the base of the switch, and its elastic arm abuts against one side of the spring 1-1.

[0037] Figure 7 The transmission principle of the double-sided pressing structure of the self-generating switch is shown. When the switch button is pressed, the switch button acts on the pressing part 2a of the corresponding side of the transmission rocker arm 2, causing the transmission rocker arm 2 to rotate around its rotation axis. This causes the rocker arm 2-3 on the other side of the transmission rocker arm 2 to swing, and pushes the spring 1-1 through the pressing part 2-4 of the spring, so that the micro generator 1 works. At the same time, after the switch button is released, the spring 1-1 can be driven to spring back to its original position under the action of the elastic reset member 3, so that the micro generator 1 generates electrical energy.

[0038] [Example 2]

[0039] This embodiment discloses a self-powered wireless switch. The self-powered wireless switch has the double-sided pressing structure of the self-powered switch in Embodiment 1 above.

[0040] Specific reference Figures 1 to 4 As shown, in this embodiment, the micro generator 1 and the elastic reset member 3 are respectively mounted on the base (the "base" part is not shown in the figure). The transmission swing rod 2 is rotatably mounted on the base. Specifically, the micro generator 1 can be fixed inside the base by a snap-fit ​​structure. When the elastic reset member 3 is a torsion spring, the spring rings on both sides of the torsion spring can be fitted onto the positioning pins on the base. The transmission swing rod 2 can be mounted on the base via the first pivot 2-1 and the second pivot 2-2 on it. A top cover 4 is also fixedly mounted on the base. The top cover 4 can also be mounted on the base by a snap-fit ​​structure. The pressing part 2a of the transmission swing rod 2 can extend to the outside of the top cover 4. A switch button that cooperates with the transmission swing rod 2 is installed on the top cover 4. When the switch button is pressed, the corresponding side of the transmission swing rod 2 drives the spring piece 1-1 to move. When the switch button is released, the elastic reset member 3 drives the spring piece 1-1 to spring back and reset, thereby driving the micro generator 1 to generate electrical energy.

[0041] In addition, a circuit board 5 is provided between the upper cover 4 and the micro generator 1. The upper cover 4 also has a spring-loaded button 4-2 corresponding to the detection switch on the circuit board 5. When the switch button is pressed, the corresponding detection switch is triggered by the spring-loaded button 4-2. The spring-loaded button 4-2 can be integrally formed on the upper cover 4. Simultaneously with the switch button being pressed, the corresponding detection switch is triggered by the spring-loaded button 4-2, thereby identifying the corresponding switch operation. To facilitate the installation of the switch button, a button mounting shaft 4-1 for mounting the switch button is also provided on the upper cover 4.

[0042] As for the circuit structure within circuit board 5 and other unmentioned structural principles of the self-generating wireless switch, they are similar to existing self-generating wireless switches and will not be explained further here.

[0043] This utility model discloses a double-sided pressing structure for a self-generating switch and a self-generating wireless switch. It utilizes two transmission levers to independently and unidirectionally press the spring of a micro generator, and uses an elastic reset component to provide a rebound force to the spring. This ensures that when one transmission lever is pressed, the other transmission lever remains stationary, thus not affecting the rapid rebound of the spring of the micro generator. This guarantees the power generation of the micro generator and the working stability of the switch, and also improves the tactile feel of the switch button.

[0044] 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.
