Description

Technical Field

[0001] This utility model relates to the field of self-generating switch technology, specifically to a swing-type self-generating switch. 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. Summary of the Invention

[0028] 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.

[0029] This embodiment provides a swing-type self-generating switch, such as... Figures 1 to 7 As shown, the device includes a housing 1 and a top cover 2 that are interlocked, forming a receiving chamber between the housing 1 and the top cover 2. A partition 3 is provided within the receiving chamber, dividing it into an upper chamber and a lower chamber. A swing assembly 4 is located in the upper chamber, and a self-generating module 5 is located in the lower chamber. The partition 3 has a through-hole 30, through which the swing assembly 4 passes into the lower chamber and is connected to the self-generating module 5, enabling the self-generating module 5 to generate electricity under the drive of the swing assembly 4.

[0030] Furthermore, the swing assembly 4 includes a force-applying rod 40, a connecting block 41, and a pressure rod 42. The middle part of the connecting block 41 is hinged to the partition 3, and the force-applying rod 40 is located at the corresponding hinge position of the connecting block 41. In order to make it easier for the user to move the force-applying rod 40, the top of the force-applying rod 40 extends out of the top cover 2. The pressure rod 42 is fixedly set at the bottom of the connecting block 41, and the pressure rod 42 can extend into the lower cavity through the through hole 30.

[0031] The top cover 2 is provided with a nut 20 that is threadedly connected to it. The nut 20 is through the top and bottom. The force-applying rod 40 passes through the nut 20. The top opening of the nut 20 is elliptical, and the major axis of the elliptical opening is adapted to the swing trajectory of the force-applying rod 40. This allows the force-applying rod 40 to swing along the major axis of the elliptical opening when it swings under the action of an external force, while also guiding the swing of the force-applying rod 40.

[0032] A return spring 43 is also provided in the upper chamber. The return spring 43 is used to reset the swing assembly 4 after it moves. The top of the return spring 43 abuts against the bottom of the connecting block 41 near the end of the pressure rod 42, and the bottom of the return spring 43 abuts against the top of the partition 3. In use, when the force rod 40 swings under the action of external force, the force rod 40 can drive the connecting block 41 to rotate. The rotation of the connecting block 41 drives the pressure rod 42 to press down through the through hole 30 to drive the self-generating module 5. At this time, the return spring 43 is compressed and stores force due to the rotation of the connecting block 41. When the external force applied to the force rod 40 disappears, the return spring 43 releases its elastic potential energy. The thrust generated by its deformation drives the connecting block 41 to rotate in the opposite direction. The reverse rotation of the connecting block 41 drives the force rod 40 to swing in the opposite direction and drives the pressure rod 42 to move upward with the connecting block 41, thereby completing the reset.

[0033] Furthermore, the self-generating module 5 includes a frame 50, an iron core 51, a coil 52, a first magnet 55 and a second magnet 56. The frame 50 has an annular groove 501 on its outer side, and the coil 52 is wound in the annular groove 501. The frame 50 has two terminals 53, and the two ends of the coil 52 are connected to different terminals 53. The terminals 53 are copper terminals.

[0034] The skeleton 50 is hollow with a through hole 54. The iron core 51 passes through the through hole 54, and both ends of the iron core 51 extend beyond the port of the through hole 54. The front end of the iron core 51 is located below the pressure rod 42 in the swing assembly 4. The first magnet 55 and the second magnet 56 are arranged separately on both sides of the end opening of the through hole 54, and the polarities of the two magnets are opposite when they are close to each other. The end of the iron core 51 passes between the first magnet 55 and the second magnet 56.

[0035] The two opposing side walls inside the clearance hole 54 are integrally formed with protrusions 541. The middle part of the iron core 51 abuts against the protrusions 541, thus maintaining a distance between the upper and lower sides of the iron core 51 and the side walls of the clearance hole 54. The iron core 51 can use the protrusions 541 as a fulcrum and swing under the action of the swing assembly 4, causing the end of the iron core 51 to switch contact between the first magnet 55 and the second magnet 56. When the end of the iron core 51 switches contact between the first magnet 55 and the second magnet 56, the magnetic field lines of the iron core 51 change direction, thereby causing the coil 52 to generate an induced current. The specific principle is the same as that of the prior art and will not be elaborated here.

[0036] Compared with the prior art, the swing fulcrum of the iron core 51 is integrally formed on the inner wall of the relief hole 54 of the skeleton 50, which is simple and compact in structure and facilitates the stable swing of the iron core 51. Moreover, the layout of the first magnet 55 and the second magnet 56 is more compact.

[0037] It should be noted that the protrusion 541 is strip-shaped and the contact surface with the iron core 51 is arc-shaped. The protrusion 541 and the iron core 51 are in close line contact, which makes it easier for the iron core 51 to swing. The end of the frame 50 is integrally injection molded with a positioning groove 502, and the first magnet 55 and the second magnet 56 are embedded in different positioning grooves 502.

[0038] In addition, the front end of the iron core 51 is provided with a lever 510. The iron core 51 and the lever 510 are fixedly connected by rivets, and the lever 510 is located below the pressure rod 42. When the pressure rod 42 in the swing assembly 4 is pressed down, it can push against the lever 510, thereby driving the iron core 51 to swing.

[0039] Furthermore, to enable the iron core 51 to reset after being driven by the swing assembly 4, a torsion spring 11 is also provided in the lower chamber. One end of the torsion spring 11 abuts against the bottom of the iron core 51, and the other end abuts against the bottom of the housing 1. It should be noted that since the front end of the iron core 51 is fixedly connected to the lever 510, one end of the torsion spring 11 can also selectively abut against the bottom of the lever 510. In addition, the torsion spring 11 can also cooperate with the reset spring 43 in the upper chamber. When the external force disappears, the two release elastic potential energy together, driving the iron core 51 to reset while simultaneously driving the swing assembly 4 to complete the reset action, thereby improving the overall reset response speed of the switch.

[0040] Furthermore, a metal shielding shell 57 is provided around the periphery of the frame 50. The metal shielding shell 57 includes a rear sheet metal part 571 and two side sheet metal parts 572. The rear sheet metal part 571 includes a U-shaped vertical plate portion 5710 and a horizontal plate portion 5711. The two horizontal plate portions 5711 are parallel to each other and surround the upper and lower sides of the first magnet 55 and the second magnet 56. The vertical plate portion 5710 surrounds the rear side of the first magnet 55 and the second magnet 56. Each side sheet metal part 572 includes an L-shaped vertical plate portion 5721 and a front plate portion 5722. The vertical plate portion 5721 surrounds the side of the coil 52. The front plate portion 5722 surrounds the front side of the frame 50. The rear end of the vertical plate portion 5721 is bent into a U-shaped limiting portion 5723. The limiting portion 5723 is stacked with the horizontal plate portion 5711.

[0041] Furthermore, the self-generating switch also includes a circuit board 6 located in the lower chamber and a wireless signal transmitting module 7 electrically connected to the circuit board 6. Specifically, the circuit board 6 is electrically connected to the self-generating module 5, with one end of the contact spring 60 connected to the circuit board 6 and the other end connected to the terminal 53 in the self-generating module 5. In use, when the iron core 51 swings, it induces a current in the coil 52, supplying power to the circuit board 6, triggering the control module therein, and activating the wireless signal transmitting module 7. The relationship between the circuit board 6 and the wireless signal transmitting module 7 is the same as in the prior art and will not be elaborated upon here.

[0042] The housing 1 has a bottom cover 10 that snaps into it, and the circuit board 6 and the wireless signal transmitting module 7 are fixedly mounted on the top of the bottom cover 10. This design allows the circuit board 6 or the wireless signal transmitting module 7 to be easily removed by opening the bottom cover 10 when they malfunction and require repair or replacement, without having to disassemble the entire switch, thus improving work efficiency during maintenance.
