When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0050] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] Please refer to the following: Figures 2 to 4 The switching mechanism provided in the embodiments of this application will now be described. The switching mechanism includes a housing 10, a switching element 30, and a transmission assembly 40; the switching element 30 is installed inside the housing 10 and is used for electrical connection with the power supply 20 and the light source assembly 50; the transmission assembly 40 is used to press the switching element 30 and is installed on the housing 10; the housing 10 is provided with a limiting structure 120, which is used to limit the range of motion of the transmission assembly 40 to protect the switching element 30.

[0053] It should be noted that the transmission component 40 can be a linkage assembly, which converts the swinging or sliding operation into a pressing or touch operation on the switch 30. The operating end of the transmission component 40 can be offset from the switch 30, that is, the operating direction (pressing or tossing direction) of the operating end of the transmission component 40 is not directly opposite the pressing direction of the switch 30, to avoid excessive compression of the switch 30 when the housing 10, which is directly opposite the switch 30, is subjected to impact. The power supply 20 can be a battery or a power adapter that is electrically connected to an external circuit, such as a lithium battery or a dry cell battery. The switch 30 can be a pressing or touch switch, such as a pressing mechanical switch. The housing 10 can be a rigid part, such as a metal or plastic part, made of materials such as aluminum alloy or ABS. The switch 30 being installed inside the housing 10 means that the switch 30 can be directly fixed to the inside of the housing 10, or fixed in the inner cavity of the housing 10 by other structures. The limiting structure 120 is a structure used to limit the range of motion of the transmission assembly 40. It can be disposed inside or outside the housing 10. When the operating end of the transmission assembly 40 is operated to press the switch 30, the limiting structure 120 can limit the further movement of the transmission assembly 40 after the switch 30 is pressed at the output end of the transmission assembly 40, preventing the output end of the transmission assembly 40 from further pressing the switch 30. The operating end of the transmission assembly 40 refers to the end of the transmission assembly 40 exposed outside the housing 10, and the output end of the transmission assembly 40 refers to the end of the transmission assembly 40 closest to the switch 30.

[0054] This embodiment employs a transmission component 40 to transmit the user's pressing operation to the interior of the housing 10. This allows the switch 30 to be installed inside the housing 10, ensuring it avoids the operating end of the transmission component 40 and preventing damage to the switch 30 caused by impact when the corresponding position on the housing 10 is subjected to an impact. Because the housing 10 has a limiting structure 120, which restricts the range of motion of the transmission component 40, when an external force impacts the transmission component 40, the limiting structure 120 prevents further compression of the switch 30. This helps prevent damage to the internal electronic switch or circuit board when the housing 10 of the switching mechanism is impacted, thus improving the reliability of the switching mechanism.

[0055] In one embodiment of this application, please refer to Figure 3 , Figure 4 and Figure 7The transmission assembly 40 includes a swing base 41, a support shaft 42, and a toggle member 43. The support shaft 42 is rotatably mounted on the housing 10, with one end extending out of the housing 10 and connected to the toggle member 43. The swing base 41 is located inside the housing 10 and is connected to the portion of the support shaft 42 that extends into the housing 10. The swing base 41 is used to push against the switch member 30. The toggle member 43 forms the operating end of the transmission assembly 40, and the swing base 41 forms the output end of the transmission assembly 40. By pushing the toggle member 43 to swing, the swing base 41 can be driven to swing, thereby achieving a pressing operation on the switch member 30 and controlling the switch member 30 to open or close.

[0056] In one embodiment of this application, please refer to Figures 2 to 4 The limiting structure 120 includes a limiting groove, in which the actuating member 43 is placed. The limiting groove is used to limit the swing angle of the actuating member 43. Thus, the limiting groove can accommodate and protect the actuating member 43, and limit its swing angle, thereby controlling the swing amplitude of the swing seat 41. Of course, in other embodiments, the limiting structure can also be a limiting block disposed outside the housing 10, which limits the swing amplitude of the actuating member 43.

[0057] In another embodiment of this application, a limiting block is provided inside the housing 10 to stop and position the swing seat 41, forming a limiting structure 120. This allows the limiting block to control the swing amplitude of the swing seat 41 when pressing the switch 30, preventing the swing seat 41 from excessively pressing the switch 30. Alternatively, in other embodiments, a limiting groove can be provided inside the housing 10 to limit the swing amplitude of the swing seat 41.

[0058] In another embodiment of this application, the support shaft 42 is provided with an adapter position, which may be a limiting groove or a limiting block provided on one side of the support shaft 42. The limiting structure 120 is used to limit the rotation angle range of the adapter position. In this way, the rotation angle of the support shaft 42 can be limited to prevent the swing seat 41 from excessively pressing the switch member 30.

[0059] Optionally, the support shaft 42 is connected to the middle of the swing seat 41 along the length direction, such as by screws.

[0060] In one embodiment of this application, the switching mechanism further includes a reset member, which is used to push the swing seat 41 to reset. The reset member is installed inside the housing 10, and its two ends are respectively connected to the housing 10 and the swing seat 41. The reset member can be a spring or a spring sheet, etc. After the toggle member 43 is pressed, the reset member pushes the swing seat 41 to separate from the switching member 30, thereby resetting the toggle member 43.

[0061] In one embodiment of this application, please refer to Figures 1 to 3An elastic body 44 is provided at one end of the swing base 41 corresponding to the switch component 30. The elastic body 44 can be a rubber block or a silicone block, etc. In this way, hard contact can prevent damage to the switch component 30 or the circuit board.

[0062] In one embodiment of this application, please refer to Figures 1 to 3 The housing 10 has a through hole 121, and the support shaft 42 passes through the through hole 121. A sealing ring 45 is fitted on the support shaft 42. The sealing ring 45 is used to seal the gap between the support shaft 42 and the inner wall of the through hole 121 of the housing 10, so as to play a waterproof role.

[0063] In one embodiment of this application, please refer to Figures 1 to 3 The housing 10 includes a cylindrical shell 11 and a cover 12 that fits over one end of the cylindrical shell 11. The switch 30 is installed inside the cover 12, and the transmission assembly 40 is installed on the cover 12. This facilitates the machining of the housing 10 and the assembly of the switch 30.

[0064] In one embodiment of this application, please refer to Figures 2 to 4 One side of the cover 12 is hinged to the cylindrical shell 11, and the other end of the cover 12 is provided with a claw 13. The cylindrical shell 11 is provided with a locking position 110 for fitting the claw 13. The locking position 110 can be a locking groove or a locking strip, etc. In this way, it is convenient for the cover 12 to be opened and closed quickly, and it can prevent the cover 12 from separating from the cylindrical shell 11 and being lost.

[0065] In one embodiment of this application, please refer to Figures 2 to 5 The claw 13 is hinged to the cover 12 at its midpoint along the length direction. The switching mechanism also includes an elastic element 131 for pushing the claw 13 into the locking position 110. Optionally, the elastic element 131 can be a compression spring, torsion spring, or spring sheet. In this way, the claw 13 can be prevented from automatically disengaging from the locking position 110, keeping the cover 12 covering the end of the cylindrical shell 11.

[0066] In another embodiment of this application, please refer to Figure 8 and Figure 9 The cover 12 and the cylindrical shell 11 are connected by screws. This allows for a detachable connection between the cover 12 and the cylindrical shell 11. In other embodiments of this application, the cover 12 and the cylindrical shell 11 may also be connected by threads or snap-fit ​​connections.

[0067] In one embodiment of this application, please refer to Figures 1 to 3The switching mechanism also includes a first circuit board 31 electrically connected to the switch element 30. One side of the first circuit board 31 is abutted against the inner wall of the housing 10, and the switch element 30 is mounted on the other side of the first circuit board 31. The output end of the transmission assembly 40 is located on the side of the switch element 30 away from the first circuit board 31. The first circuit board 31 is used to electrically connect the power supply 20 and the light source assembly 50. In this way, the connection position between the switch element 30 and the first circuit board 31 can be kept stable when the transmission assembly 40 presses the switch element 30, preventing the switch element 30 and the first circuit board 31 from shifting under pressure. Specifically, one side of the first circuit board 31 is abutted against the bottom of the cover 12, and the swing seat 41 is located on the side of the switch element 30 away from the first circuit board 31. The bottom plane of the cover 12 can support the first circuit board 31, which is beneficial for heat dissipation of the first circuit board 31 and prevents the first circuit board 31 from being damaged when pressed.

[0068] In one embodiment of this application, please refer to Figures 3 to 6 The first circuit board 31 includes a fixed section 311, an output section 313, and a connecting section 312.

A second circuit board 21 is installed inside the housing 10. The second circuit board 21 is used for electrical connection with the light source assembly 50 and the power supply 20. The second circuit board 21 is provided with a terminal block that can be detachably connected to the output section 313. This facilitates the detachable connection of the first circuit board 31 with the power supply 20 and the light source assembly 50. The first circuit board 31 can be a flexible board or a rigid board.

[0069] Specifically, the fixing section 311 is attached to the bottom of the cover 12. This allows the switch element 30 to be conveniently placed at the bottom of the cover 12, and the transmission assembly 40 and the switch element 30 to be conveniently placed on the cover 12, facilitating the assembly of the switching mechanism.

[0070] In one embodiment of this application, please refer to Figures 3 to 6 A pressure seat 14 is detachably installed inside the housing 10.

In this way, the position of the switch 30 and the first circuit board 31 can be kept stable.

[0072] In one embodiment of this application, please refer to Figures 3 to 6The housing 10 has a positioning protrusion 122 inside, and the first circuit board 31 has a positioning hole 310. The positioning protrusion 122 is inserted into the positioning hole 310.
