Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a self-generating module and a switch incorporating it. Background Technology

[0002] Existing indoor lighting equipment also employs wireless switches that connect wirelessly to the luminaires and control them via a switching mechanism. For example, Chinese patent document CN205005033U discloses a self-generating wireless switch module suitable for detachable assembly with a switch board to form a self-generating wireless switch. This module includes a micro-generator and a controller. The micro-generator comprises a magnetic assembly, a coil core, an electromagnetic coil, an elastic element, a swing arm, and a fulcrum. When the switch board is pressed, it drives the swing arm to move, causing the elastic element to deform. When the elastic element returns to its original position, it drives the coil core to move, alternately contacting two different magnetic plates of the magnetic assembly. This induces a current in the electromagnetic coil, which powers the controller to generate wireless control commands.

[0003] For example, Chinese patent document CN110350755B discloses a self-generating wireless switch and its application. The self-generating wireless switch includes: a controller for generating a wireless control signal; a switch plate driven to generate mechanical energy; and a micro generator operatively connected to the switch plate, which includes a magnetic group and a coil group. The magnetic group and the coil group are movable relative to each other to convert the mechanical energy from the switch plate into electrical energy and supply it to the controller so as to drive the controller in a battery-free manner.

[0004] In existing technology, the magnetic field lines of the iron core are changed by swinging the iron core and contacting different magnetic plates, so as to generate an induced current in the coil, power the circuit board, and transmit wireless signals.

[0005] Existing technologies support the iron core using a separate support plate or an extended structure of the magnetic guide plate. Since the iron core must pass through the frame before contacting the magnetic guide plate, and the fulcrum for the core's oscillation is located outside the frame, the frame cannot be made too long, otherwise it will affect the core's oscillation. The location of the fulcrum limits the length of the frame, which in turn affects the number of turns in the coil, thus constraining the overall performance of the power generation module. Utility Model Content

[0006] In view of the above-mentioned technical problems, the present invention provides a self-generating module and a switch with the same.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] The switch in this embodiment, such as Figures 1 to 8 As shown, it includes a housing 1, a button 2, a circuit board 3, and a self-generating module 6. The self-generating module 6 includes a frame 61, an iron core 62, a coil 63, a first magnet 64, and a second magnet 65. The frame 61 has an annular groove 611 on its outer side, and the coil 63 is wound in the annular groove 611. The frame 61 has two terminals 66, and the two ends of the coil 63 are connected to different terminals 66. The terminals 66 are copper terminals.

[0042] The skeleton 61 is hollow with a through hole 612. A long, block-shaped iron core 62 passes through the through hole 612, and both ends of the iron core 62 extend beyond the port of the through hole 612. A first magnet 64 and a second magnet 65 are arranged separately on both sides of the end opening of the through hole 612, and the polarities of the two magnets are opposite when they are close to each other. The end of the iron core 62 passes between the first magnet 64 and the second magnet 65.

[0043] The inner side walls of the clearance hole 612 are integrally formed with protrusions 613 facing each other. The middle part of the iron core 62 abuts against the protrusions 613, so that the upper and lower sides of the iron core 62 maintain a distance from the side walls of the clearance hole 612. The iron core 62 can swing with the protrusions 613 as a fulcrum, so that the end of the iron core 62 switches contact between the first magnet 64 and the second magnet 65. When the end of the iron core 62 switches contact between the first magnet 64 and the second magnet 65, the magnetic field lines of the iron core 62 change direction, thereby inducing a current in the coil 63. The specific principle is the same as that of the prior art, and will not be elaborated here.

[0044] Compared with the prior art, the swing fulcrum of the iron core 62 is integrally formed on the inner wall of the relief hole 612 of the skeleton 61, which is simple and compact in structure and facilitates the stable swing of the iron core 62. Moreover, the layout of the first magnet 64 and the second magnet 65 is more compact.

[0045] In this embodiment, a metal shielding shell 67 is provided around the periphery of the frame 61. The metal shielding shell 67 includes a rear sheet metal part 671 and two side sheet metal parts 672. The rear sheet metal part 671 includes a U-shaped vertical plate portion 6711 and a horizontal plate portion 6712. The two horizontal plate portions 6712 are parallel to each other and surround the upper and lower sides of the first magnet 64 and the second magnet 65. The vertical plate portion 6711 surrounds the rear side of the first magnet 64 and the second magnet 65. Each side sheet metal part 672 includes an L-shaped vertical plate portion 6721 and a front plate portion 6722. The vertical plate portion 6721 surrounds the side of the coil 63, and the front plate portion 6722 surrounds the front side of the frame 61. The rear end of the vertical plate portion 6721 is bent into a U-shaped limiting portion 6723. The limiting portion 6723 and the horizontal plate portion 6712 are stacked.

[0046] Specifically, the protrusion 613 is strip-shaped and the contact surface with the iron core 62 is arc-shaped. The protrusion 613 and the iron core 62 are in near-line contact, which makes it easier for the iron core 62 to swing.

[0047] Specifically, the end of the skeleton 61 is integrally injection molded with a positioning groove 614, and the first magnet 64 and the second magnet 65 are embedded in different positioning grooves 614.

[0048] Specifically, a lever 621 is fixed to the front end of the iron core 62. The iron core 62 and the lever 621 are fixed together by rivets 622.

[0049] In this embodiment, circuit board 3 and self-generating module 6 are installed inside housing 1. Terminal 66 is electrically connected to circuit board 3. Button 2 is hinged to housing 1. Spring 4 (torsion spring) is provided inside housing 1 to keep iron core 62 and button 2 in a preset posture. When external force is applied to button 2, it can overcome the force of spring 4 and drive iron core 62 to swing. The swing of iron core 62 induces current in coil 63, which powers circuit board 3, triggers the control module therein, and starts wireless signal transmission module 5. The relationship between circuit board 3 and wireless signal transmission module is the same as in the prior art and will not be described in detail here.

[0050] Specifically, the circuit board 3 is provided with a U-shaped contact spring 31, one end of which is connected to the circuit board 3 and the other end is connected to the terminal block 66.

[0051] Specifically, the housing 1 includes a main body 11, a bottom cover 14, and a top cover 15. The main body 11 has an upper chamber 12 and a lower chamber 13. The self-generating module 6 is fixed in the upper chamber 12, and the circuit board 3 is installed in the lower chamber 13. The terminal block 66 passes through the lower chamber 13 to connect the circuit board 3. The bottom cover 14 and the top cover 15 are respectively connected to the main body 11 by a hook structure. Similarly, the bottom cover 14 and the top cover 15 are connected to each other. The top cover 15 is provided with a hinge groove 16 for the hinge button 2.

[0052] Specifically, the button 2 is integrally formed with a pressure tongue 21 and a stop hook 22. The stop hook 22 cooperates with the top cover 15 to limit the upward movement of the button 2. When the button 2 is pressed down, the pressure tongue 21 abuts against the lever 621, thereby driving the iron core 62 to swing.
