Technical Field
[0001] This utility model relates to the field of switch technology, and in particular discloses a self-generating auxiliary switch. Background Technology
[0002] In modern home and building electrical systems, smart switches are increasingly widely used. Traditional smart switches typically require an external power source or battery replacements to operate, which not only increases the complexity of installation and maintenance but may also cause the switch to malfunction due to battery depletion or power failure. Furthermore, in certain scenarios, such as humid environments or locations requiring frequent relocation, the safety and convenience of traditional switches are also limited.
[0003] The emergence of self-generating technology has provided a new solution for smart switches. Through energy harvesting technology, switches can convert minute amounts of energy, such as mechanical energy, into electrical energy, thus achieving self-powered operation without the need for an external power source or batteries. However, existing self-generating switches still have shortcomings in terms of power generation efficiency, structural design, and functional versatility. For example, the power generation device has a complex structure, poor tactile feedback, and unstable signal transmission. Therefore, there is a need for a self-generating auxiliary switch that is simple in structure, highly efficient in power generation, easy to use, and safe and reliable. Utility Model Content
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a self-generating auxiliary switch.
[0005] To achieve the above objectives, this utility model provides a self-generating auxiliary switch, comprising a pressing module, a power generation module, an electronic control module, and a housing module. The pressing module has a pressing panel, and the housing module has an accommodating cavity and an opening. The power generation module and the electronic control module are located in the accommodating cavity. The pressing panel is movably mounted on the housing module and covers the opening. The power generation module has an electromagnetic induction component, which includes a coil and a magnet that can reciprocate relative to the coil. The coil cuts magnetic field lines to provide power to the electronic control module. The pressing panel triggers the electronic control module to send a wireless signal to control the on / off state of an external main switch.
[0006] Furthermore, the electromagnetic induction component also has a bracket and magnetic sheets. The coil is wound on the bracket to form a cavity, and the magnet is located in the cavity. There are multiple magnetic sheets, which are snapped together by the bracket and wrapped around the outside of the coil. The multiple magnetic sheets and the magnet form a closed magnetic circuit, which improves the magnetic flux and power generation efficiency.
[0007] Furthermore, the pressing panel reciprocates elastically relative to the housing module, and the pressing panel drives the magnet to move relative to the coil, causing the coil to cut magnetic field lines to generate electricity.
[0008] Furthermore, the power generation module also has a force-saving button and an elastic pressing handle; the elastic pressing handle is connected to a magnet; the force-saving button has a lever structure, one end of the force-saving button abuts against the housing module to form a fulcrum, and the other end of the force-saving button is the force-bearing end; when the pressing panel moves, it presses down on the force-bearing end, causing the force-saving button to drive the elastic pressing handle to move the magnet and generate current; the restoring force generated by the pressure on the elastic pressing handle drives the magnet to reset, the magnet reset pushes the force-saving button to reset, and thus the pressing panel resets.
[0009] Furthermore, the force-receiving end has a body and support arms extending vertically from both ends of the body, and the fulcrum is formed by the end of the support arm that abuts against the housing module; the electromagnetic induction component is located between the two support arms; a protruding shank is provided at the end of the force-receiving end near the elastic pressing handle, and the bottom of the shank abuts against the top of the elastic pressing handle.
[0010] Furthermore, the elastic pressing handle has a tongue and an elastic element. One end of the tongue is fixedly connected to a magnet, and the other end of the tongue extends to the bottom of the handle. The elastic element is located below the tongue and abuts against the tongue.
[0011] Furthermore, the electronic control module has a wireless communication unit with an operating frequency of 433MHz and supports AES-128 encrypted communication.
[0012] Furthermore, the electronic control module has a micro switch, which, when triggered by pressing the panel, sends a wireless signal to control the external main switch.
[0013] Furthermore, the housing module includes a bottom shell and a middle shell, with the middle shell located between the pressing panel and the bottom shell; the pressing panel has a frame mounted on the bottom shell and an elastic cantilever mounted on the frame for easy pressing by the user.
[0014] Furthermore, the self-generating auxiliary switch also has a waterproof module with an elastic waterproof layer that covers the power generation module and the electronic control module. The elastic waterproof layer is pressed between the middle shell and the bottom shell to form a sealed structure. The middle shell has an operating hole through which the pressing module passes and abuts against the elastic waterproof layer. When the user operates the pressing panel, the elastic waterproof layer undergoes elastic deformation due to the pressure of the pressing panel, which drives the electromagnetic induction component in the power generation module.
[0015] Furthermore, the self-generating auxiliary switch also has a status indication module, which includes a light-transmitting hole on the pressing panel and an LED on the electronic control module; the light from the LED is emitted through the light-transmitting hole, and the LED displays the working status of the auxiliary switch through its flashing frequency and color.
[0016] The beneficial effects of this utility model are:
[0017] (1) High-efficiency self-powered: The magnetic sheet structure is increased to form a closed magnetic circuit design, which improves the utilization rate of magnetic flux;
[0018] (2) Dual-point effortless pressing: The combination of effortless pressing plate and elastic pressing handle reduces pressing resistance and amplifies pressing stroke by lever principle, making pressing operation smoother. In addition, the elastic pressing handle's restoring force can automatically drive each component to reset, providing a good user experience.
[0019] (3) Waterproof and moisture-proof: The elastic waterproof layer of the waterproof module can effectively protect the power generation module and the electrical control module, prevent moisture intrusion and malfunction, and is suitable for humid environments.
[0020] (4) Intelligent interaction: The status indicator module displays the working status of the switch through the flashing frequency and color of the dual-color LED, making it convenient for users to understand the real-time status of the switch. Attached Figure Description

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0029] Please see Figures 1 to 6 As shown, this utility model discloses a self-generating auxiliary switch, comprising a pressing module 1, a power generation module 2, an electronic control module 3, and a housing module 4. The pressing module 1 has a pressing panel 11, and the housing module 4 has an accommodating cavity and an opening. The power generation module 2 and the electronic control module 3 are located in the accommodating cavity. The pressing panel 11 is movably mounted on the housing module 4 and covers the opening. The power generation module 2 has an electromagnetic induction component 21, which includes a coil 212 and a magnet 211 that can reciprocate relative to the coil 212. The coil 212 cuts magnetic field lines to provide power to the electronic control module 3. The pressing panel 11 triggers the electronic control module 3 to send a wireless signal to control the on / off state of an external main switch.
[0030] In actual use, the bottom shell 41 is of type 86, with its four ends bent to form side plates. A square annular surrounding plate protrudes from the center of the bottom shell 41. The middle shell 42 is smaller than the bottom shell 41, and its four ends are bent to form convex plates. During installation, the convex plates surround the outside of the surrounding plates, and the middle shell 42 is fixed to the bottom shell 41 with screws. The convex plates, surrounding plates, bottom shell 41, and middle shell 42 together form an accommodating cavity. One end of the bottom shell 41 is provided with a connecting end for a rotating shaft. The number of connecting ends is the same as the number of pressing modules 1. In this embodiment, the pressing module 1 includes three pressing panels 11, so the number of connecting ends is also 3. This auxiliary switch can be matched one-to-one with an external main switch; or one auxiliary switch can be matched with multiple external main switches. In this embodiment, the auxiliary switch includes three pressing panels 11, each of which can be matched with one external main switch; or multiple auxiliary switches can be matched with the same main switch.
[0031] Specifically, the electromagnetic induction component 21 also has a bracket 213 and magnetic sheets 214. The coil 212 is wound around the bracket 213 to form a cavity, and the magnet 211 is located in the cavity. There are multiple magnetic sheets 214, which are snapped together by the bracket 213 and surround the outside of the coil 212. The multiple magnetic sheets 214 and the magnet 211 form a closed magnetic circuit, which improves the magnetic flux and power generation efficiency.
[0032] In actual use, the magnetic conductive sheet 214 is made of silicon steel, and a rectangular limiting groove is provided at the center of the bottom shell 41. The electromagnetic induction component 21 is set in the limiting groove, and the magnetic conductive sheet 214 wraps around the coil 212. The setting of the magnetic conductive sheet 214 significantly reduces the loss of magnetic flux, allowing more magnetic lines of force to pass through the coil 212, thereby improving the effective utilization rate of magnetic flux.
[0033] Specifically, the pressing panel 11 reciprocates elastically relative to the housing module 4, and the pressing panel 11 drives the magnet 211 to move relative to the coil 212, so that the coil 212 cuts the magnetic field lines to generate electricity.
[0034] Specifically, the power generation module 2 also has a force-saving button 22 and an elastic pressing handle 23; the elastic pressing handle 23 is connected to a magnet 211; the force-saving button 22 has a lever structure, one end of the force-saving button 22 abuts against the housing module 4 to form a fulcrum 224, and the other end of the force-saving button 22 is a force-bearing end 222; when the pressing panel 11 moves, it presses down on the force-bearing end 222, causing the force-saving button 22 to drive the elastic pressing handle 23 to drive the magnet 211 to move and generate current; the restoring force generated by the elastic pressing handle 23 under pressure drives the magnet 211 to reset, and the reset of the magnet 211 pushes the force-saving button 22 to reset, thereby causing the pressing panel 11 to reset.
[0035] In actual use, the principle of the power generation module 2 is that the magnet 211 moves within the coil 212, cutting magnetic field lines to generate current. Therefore, one end of the elastic pressing handle 23 is directly connected to the magnet 211 within the coil 212, and the other end protrudes from the magnet 211 and the coil 212, contacting the middle of the force-saving button 22. The force-saving button 22 is perpendicular to the three pressing panels 11, meaning that the user can trigger the force-saving button 22 and the elastic pressing handle 23 by pressing any one of the pressing panels 11, and the elastic pressing handle 23 will return to its original state due to the elastic force generated by its deformation.
[0036] Specifically, the force-receiving end 222 has a body and support arms 223 extending vertically from both ends of the body. The fulcrum 224 is formed by the end of the support arm 223 that abuts against the housing module 4. The electromagnetic induction component 21 is located between the two support arms 223. A protruding handle 221 is provided at the end of the force-receiving end 222 near the elastic pressing handle 23. The bottom of the protruding handle 221 abuts against the top of the elastic pressing handle 23.
[0037] In actual use, the base is provided with a slot, one side of the support arm 223 of the effort-saving button 22 is fixed in the slot, and the other side abuts against the limiting groove to form a fulcrum 224. The middle part of the force-bearing end 222 of the effort-saving button 22 is provided with a protruding handle 221 that abuts against the elastic pressing handle 23. The protruding handle 221 extends upward beyond the effort-saving button 22, which at this time extends the effort-saving button 22 and enlarges the pressing stroke, but reduces the longitudinal space required by the effort-saving button 22, making the pressing operation smoother. Moreover, the restoring force of the elastic pressing handle 23 can automatically drive the components to reset, providing a good user experience.
[0038] Specifically, the elastic pressing handle 23 has a tongue 231 and an elastic element 232. One end of the tongue 231 is fixedly connected to the magnet 211, and the other end of the tongue 231 extends to the bottom of the handle 221. The elastic element 232 is located below the tongue 231 and abuts against the tongue 231.
[0039] In actual use, the width of one end of the elastic pressing handle 23 is greater than the width of the magnet 211, and screws are provided on both sides to fix it to the magnet 211. The other end of the elastic pressing handle 23 is a narrower protrusion 231, which is located below the protrusion handle 221 and is completely covered by the protrusion handle 221. The elastic element 232 is a double torsion spring. The two lugs of the double torsion spring are fixed to the two ends of the limiting groove, and the elastic rod in the middle of the double torsion spring is located below the protrusion 231. When the protrusion 231 is pressed down by the protrusion handle 221, the elastic rod is pressed down by the protrusion 231, producing elastic deformation, storing and releasing energy.
[0040] Specifically, the electronic control module 3 has a wireless communication unit with an operating frequency of 433MHz and supports AES-128 encrypted communication.
[0041] In actual use, the electronic control module 3 has a main control unit, a 433MHz radio frequency transceiver unit, an encryption security unit, an energy management unit, a signal triggering unit, and a reserved 2.4GHz stamp hole pad.
[0042] Specifically, the electronic control module 3 has a micro switch 31. When the micro switch 31 is triggered by pressing the panel 11, the electronic control module 3 sends a wireless signal to control the external main switch.
[0043] In actual use, the number of microswitches 31 corresponds to the number of pressing panels 11. The electronic control module 3 is also equipped with time-skipping spread spectrum technology to avoid interference from signals on the same frequency.
[0044] Specifically, the housing module 4 includes a bottom shell 41 and a middle shell 42, with the middle shell 42 located between the pressing panel 11 and the bottom shell 41; the pressing panel 11 has a frame mounted on the bottom shell 41 and an elastic cantilever mounted on the frame for easy pressing by the user.
[0045] In actual use, there are 3 pressing panels 11. One end of the pressing panel 11 is provided with a rotating shaft, which is rotatably connected to the connecting end of the bottom shell 41. The other end of the pressing panel 11 is provided with an interface retainer. The middle shell 42 is provided with a sliding groove at the end near the interface retainer. When one end of the pressing panel 11 rotates around the rotating shaft, the interface retainer slides along the sliding groove.
[0046] Specifically, the self-generating auxiliary switch also has a waterproof module 5, which has an elastic waterproof layer that covers the power generation module 2 and the electronic control module 3. The elastic waterproof layer is pressed between the middle shell 42 and the bottom shell 41 to form a sealed structure. The middle shell 42 has an operation hole 421, through which the pressing module 1 passes and abuts against the elastic waterproof layer. When the user operates the pressing panel 11, the elastic waterproof layer undergoes elastic deformation due to the pressure of the pressing panel 11, and drives the electromagnetic induction component 21 in the power generation module 2.
[0047] In actual use, the shape and outline of the elastic waterproof layer are similar to those of the middle shell 42. The elastic waterproof layer can fit the middle shell 42 well with the power generation module 2 and the electronic control module 3, ensuring a good user experience. The middle shell 42 has through holes in the parts that abut against the first and second contacts, allowing the first and second contacts to pass through the through holes and directly abut against the elastic waterproof layer below the middle shell 42.
[0048] Specifically, the self-generating auxiliary switch also has a status indicator module, which includes a light-transmitting hole 12 on the pressing panel 11 and an LED 32 on the electronic control module 3; the light from the LED 32 is emitted through the light-transmitting hole 12, and the LED 32 displays the working status of the auxiliary switch through its flashing frequency and color.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
