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.

[0052] 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.

[0053] Please refer to the diagram as well. Figure 1 , Figure 2 and Figure 7 The lamp provided in the embodiments of this application will now be described. The lamp includes a light source assembly 50, a focusing assembly 60, and a first reset member 70; the light source assembly 50 includes a lens barrel 51, a lens 52, a light source 53, and a fixing base 54. The lens 52 and the light source 53 are located inside the lens barrel 51. The fixing base 54 is movably installed at one end of the lens barrel 51, and the light source 53 is installed at the end of the fixing base 54 that extends into the lens barrel 51; the focusing assembly 60 is movably installed inside the lens barrel 51 and is connected to the lens 52; the lens barrel 51 is used to drive the focusing assembly 60 to adjust the distance between the light source 53 and the lens 52; the first reset member 70 is installed inside the lens barrel 51 and is used to lock the lens barrel 51 and the fixing base 54.

[0054] It should be noted that one end of the mounting base 54 is movably connected to the lens barrel 51, and the other end of the mounting base 54 is used to connect to the housing 10 or an external connecting seat. Under the action of external force, the lens barrel 51 can move relative to the mounting base 54, thereby unlocking the lens barrel 51 from the mounting base 54. When the lens barrel 51 is unlocked from the mounting base 54, adjusting the lens barrel 51 can drive the adjusting component 60 to adjust the vertical distance between the lens 52 and the light source 53, thereby adjusting the focus. When the external force is removed, the first reset component 70 can drive the lens barrel 51 to lock the mounting base 54, so as to maintain the relative stability of the positions of the lens barrel 51 and the mounting base 54, and to a certain extent prevent the lens barrel 51 from moving relative to the mounting base 54 when the lamp is impacted.

[0055] This embodiment of the application, by employing the aforementioned focusing assembly 60, can adjust the position of the lens 52 to achieve focus adjustment. By using a lens barrel 51 movably connected to a fixed base 54, the lens barrel 51 drives the focusing assembly 60. After the lens barrel 51 and the fixed base 54 are unlocked, the lens barrel 51 can move relative to the fixed base 54 under the action of external force, thereby driving the focusing assembly 60 to adjust the position of the lens 52. Through the first reset member 70, when the external force is removed, it can drive the lens barrel 51 and the fixed base 54 to automatically lock, maintaining the relative stability of the positions of the lens barrel 51 and the fixed base 54, so as to a certain extent prevent the focusing assembly 60 from moving when the lamp is impacted, keeping the position of the lens 52 stable, and keeping the focus of the lamp stable.

[0056] In one embodiment of this application, please refer to Figures 7 to 12 The focusing assembly 60 includes a lens frame 61 connected to the lens 52 and an adjusting ring 63 rotatably sleeved on the lens frame 61. The lens frame 61 is slidably connected to the fixed base 54, and the adjusting ring 63 is connected to the lens barrel 51. When the lens barrel 51 is unlocked from the fixed base 54, the lens barrel 51 can rotate relative to the fixed base 54. When the adjusting ring 63 rotates, it can drive the lens frame 61 to slide along the fixed base 54. The slidable connection between the lens frame 61 and the fixed base 54 facilitates guiding the lens 52 closer to or further away from the light source 53. When the lens barrel 51 is unlocked from the fixed base 54, the lens barrel 51 can lock the adjusting ring 63, so rotating the lens barrel 51 will drive the adjusting ring 63 to rotate.

[0057] In one embodiment of this application, please refer to Figure 7 , Figure 11 and Figure 12 The adjusting ring 63 has a spiral hole 630, and the frame 61 has a first protrusion 62 that engages with the spiral hole 630. When the first protrusion 62 slides along the spiral hole 630, the frame 61 and the adjusting ring 63 move relative to the axis of the lens barrel 51, causing the lens 52 to move closer to or further away from the light source 53. Specifically, when the lens barrel 51 is rotated, the adjusting ring 63 connects to the lens barrel 51, the rotation angle between the adjusting ring 63 and the lens barrel 51 is locked, the position of the adjusting ring 63 within the lens barrel 51 along the axis is fixed, and the frame 61 moves relative to the lens barrel 51 along the axis. In other embodiments of this application, the adjusting ring 63 may also be threadedly connected to the frame 61, or the frame 61 may have a spiral hole, and the adjusting ring 63 may have a first protrusion 62 that slides into the spiral hole.

[0058] In one embodiment of this application, please refer to Figure 7 , Figure 11 and Figure 12The frame 61 is provided with a first sliding groove 610, and the fixed base 54 is provided with a slider 542, which slides in conjunction with the first sliding groove 610. Thus, when the lens barrel 51 is rotated, the slider 542 can restrict the frame 61 from rotating relative to the lens barrel 51, and guide the frame 61 to slide along the axis of the fixed base 54.

[0059] In one embodiment of this application, please refer to Figures 7 to 12 The fixed base 54 has a limiting ring 541 at one end that extends into the lens barrel 51. The lens barrel 51 has an annular groove 510, and the limiting ring 541 is confined within the annular groove 510. The limiting ring 541 can rotate within the annular groove 510 and slide along the axial direction within the annular groove 510. This prevents the fixed base 54 from separating from the lens barrel 51, and allows the lens barrel 51 to rotate and slide relative to the fixed base 54, so as to drive the adjusting ring 63 to rotate using the lens barrel 51.

[0060] Furthermore, the lens barrel 51 is provided with a locking part 5111, and the fixed seat 54 is provided with a first locking position 543. The first locking position 543 is used to cooperate with the locking part 5111 to restrict the rotation of the lens barrel 51 relative to the fixed seat 54. The focusing assembly 60 is provided with a second locking position 631. The second locking position 631 is used to cooperate with the locking part 5111 to restrict the rotation of the lens barrel 51 relative to the adjusting ring 63. The first locking position 543 and the second locking position 631 are located on the sliding path of the locking part 5111 along the axial direction of the annular groove 510. When the lens barrel 51 slides relative to the fixed base 54 to the position where the locking part 5111 engages with the first locking position 543, the rotation angle between the lens barrel 51 and the fixed base 54 is locked, preventing rotation. When the lens barrel 51 slides relative to the fixed base 54 to the position where the locking part 5111 engages with the second locking position 631, the locking part 5111 disengages from the first locking position 543, allowing the lens barrel 51 to rotate relative to the fixed base 54. Rotating the lens barrel 51 also drives the adjusting ring 63 to rotate. Specifically, the adjusting ring 63 has a second locking position 631. Thus, when the locking part 5111 engages with the second locking position 631, the lens barrel 51 and the adjusting ring 63 rotate synchronously.

[0061] In one embodiment of this application, please refer to Figures 7 to 12 One end of the adjusting ring 63 is rotatably connected to the fixed base 54, and the other end of the adjusting ring 63 is slidably engaged with the lens barrel 51, meaning that the lens barrel 51 can slide relative to the adjusting ring 63 along its axial direction. This helps to improve the stability of the adjusting ring 63.

[0062] Furthermore, the first reset member 70 is an elastic member, installed within the annular groove 510, with both ends of the first reset member 70 abutting against the limiting ring 541 and the sidewall of the annular groove 510 near the light-emitting side, respectively. That is, the first reset member 70 is used to push the fixed base 54 and the lens barrel 51 away from each other, so that the locking part 5111 engages with the first locking position 543 to lock the rotation angle between the lens barrel 51 and the fixed base 54. When the lens barrel 51 is pushed to slide towards the fixed base 54, the rotation angle between the lens barrel 51 and the fixed base 54 can be unlocked. Thus, after adjustment, the first reset member 70 can push the lens barrel 51 to slide, automatically locking its rotation angle with the fixed base 54 to maintain stable focusing.

[0063] When the lens barrel 51 is pushed close to the fixed base 54, the lens barrel 51 slides along the axial direction of the fixed base 54, and the locking part 5111 is unlocked and separated from the first locking position 543, the lens barrel 51 can rotate relative to the fixed base 54; when the lens barrel 51 slides to the point where the locking part 5111 engages with the second locking position 631 and locks, the lens barrel 51 can rotate relative to the fixed base 54, thereby driving the adjusting ring 63 to rotate relative to the fixed base 54. The fixed base 54 can restrict the movement of the adjusting ring 63 along its axial direction, so that the frame 61 slides relative to the fixed base 54 along the axial direction of the lens barrel 51.

[0064] Optionally, the locking part 5111 is a first protrusion, and the first locking position 543 is a first notch. The first protrusion can enter or leave the first notch along the axial direction of the fixing seat 54; the second locking position 631 is a second notch, and the first protrusion can enter or leave the second notch along the axial direction of the fixing seat 54. When the first protrusion slides into the first notch, the rotation angle between the lens barrel 51 and the fixing seat 54 is locked, and they cannot rotate relative to each other. When the first protrusion leaves the first notch, the rotation angle between the lens barrel 51 and the fixing seat 54 is unlocked, and they can rotate relative to each other. When the first protrusion is inserted into the second notch, the rotation angle between the lens barrel 51 and the adjusting ring 63 is locked, and they cannot rotate relative to each other. Rotating the lens barrel 51 will drive the adjusting ring 63 to rotate synchronously. Pushing the lens barrel 51 along the axial direction of the fixing seat 54 will allow the first protrusion to enter or leave the first or second notch.

[0065] Optionally, there can be multiple first locking positions 543, arranged circumferentially around the fixing seat 54. This allows the lens barrel 51 to be locked relative to the fixing seat 54 when rotated to different angles. Specifically, the fixing seat 54 has a first protruding ring at one end extending into the lens barrel 51, and the first locking positions 543 are located on the first protruding ring. On the side of the first protruding ring near the housing 10, the outer diameter of the fixing seat 54 is smaller than the first protruding ring, so it will not interfere with the first protruding strip.

[0066] In one embodiment of this application, please refer to Figures 7 to 12When the lens barrel 51 slides toward the mounting base 54 until the locking part 5111 moves away from the first locking position 543, the locking part 5111 engages with the second locking position 631 to lock the rotation angle of the adjusting ring 63, preventing the adjusting ring 63 from rotating relative to the lens barrel 51. That is, when the locking part 5111 unlocks and separates from the first locking position 543, the locking part 5111 engages with the second locking position 631 to lock. Thus, when the lens barrel 51 unlocks from the mounting base 54, the lens barrel 51 locks the rotation angle of the adjusting ring 63, and rotating the lens barrel 51 will cause the adjusting ring 63 to rotate.

[0067] Optionally, there are multiple second locking positions 631. The distance between two adjacent second locking positions 631 is equal to the distance between two adjacent first locking positions 543, and the multiple second locking positions 631 can correspond one-to-one with multiple first locking positions 543. This allows the locking part 5111 to cooperate with different second locking positions 631 to adjust the focal length. Specifically, the end of the adjusting ring 63 away from the fixed base 54 is provided with a second protruding ring, and the second locking position 631 is located on the second protruding ring. The second protruding ring is located on the side of the first protruding ring away from the fixed base 54. On the side of the second protruding ring closer to the fixed base 54, the outer diameter of the adjusting ring 63 is smaller than that of the second protruding ring, so it will not interfere with the first protruding strip.

[0068] In one embodiment of this application, please refer to Figures 7 to 12 There are two locking portions 5111, arranged along the axis of the lens barrel 51, and the distance between the two locking portions 5111 is greater than or equal to the width of the first locking position 543. Thus, when the first locking position 543 is between the two locking portions 5111, the locking portions 5111 are separated from the first locking position 543 and unlocked. Specifically, the first reset member 70 is used to push the fixing seat 54 and the lens barrel 51 away from each other, so that the locking portion 5111 closest to the fixing seat 54 engages and locks with the first locking position 543. This reduces the sliding distance between the lens barrel 51 and the fixing seat 54 when the locking portion 5111 switches between the first locking position 543 and the second locking position 631.

[0069] Optionally, the distance between the two locking parts 5111 is less than the distance between the ends of the first locking position 543 and the second locking position 631 near the light-emitting side. The distance between the ends of the first locking position 543 and the second locking position 631 near the light-emitting side can be understood as the sum of the width of the first convex ring and the distance between the first convex strip and the second convex strip. When the first locking position 543 is between the two locking parts 5111, and one of the locking parts 5111 near the light-emitting side is at least partially engaged in the second locking position 631, rotating the lens barrel 51 will not be interfered with by the fixing seat 54, and will drive the adjusting ring 63 to rotate.

[0070] Optionally, the lens barrel 51 includes a first barrel 511 and a second barrel 512, which are threaded together, and an annular groove 510 is formed on the inner side of the connection position of the first barrel 511 and the second barrel 512. This facilitates the assembly and processing of the light source assembly 50.

[0071] Optionally, the first reset member 70 can be a spring or an annular spring pad, with both ends of the first reset member 70 abutting against the sidewalls of the limiting ring 541 and the annular groove 510 away from the fixed base 54, respectively. In this way, the lens barrel 51 can be pushed to slide towards the light-emitting side.

[0072] Optionally, the mounting base 54 has an annular groove on its outer side, and a sealing ring 64 is fitted inside the annular groove. The sealing ring 64 seals the gap between the outer periphery of the mounting base 54 and the inner wall of the lens barrel 51. In this way, it not only achieves a sealing effect, but also helps to improve the stability between the lens barrel 51 and the mounting base 54.

[0073] Optionally, the frame 61 has an annular groove on its outer periphery, and a sealing ring 64 is fitted inside the groove. The sealing ring 64 seals the gap between the outer periphery of the frame 61 and the inner wall of the lens barrel 51. This achieves a sealing effect on the one hand, and helps to improve the stability between the lens barrel 51 and the frame 61 on the other.

[0074] Optionally, an annular groove is formed inside the frame 61 corresponding to the position of the lens 52, and a sealing ring 64 is provided in the annular groove to seal the gap between the inner wall of the frame 61 and the lens 52. In this way, a sealing effect can be achieved, which helps to improve the stability of the lens 52.

[0075] In one embodiment of this application, please refer to Figures 7 to 12 The fixed base 54 is provided with a limiting part 544, and the frame 61 is provided with a second sliding groove 611. The limiting part 544 is slidably disposed in the second sliding groove 611, and a first limiting wall 612 is provided at one end of the second sliding groove 611 near the fixed base 54. This can limit the sliding distance of the frame 61 along the axis of the fixed base 54 and prevent the frame 61 from separating from the fixed base 54.

[0076] Optionally, a limiting plate 632 is provided at one end of the adjusting ring 63 near the fixed base 54, and a first limiting groove 540 is provided on the fixed base 54. The first limiting groove 540 is used to limit the sliding of the adjusting ring 63 along the axial direction of the fixed base 54; the limiting plate 632 is confined within the first limiting groove 540, and the frame 61 is located on the side of the limiting plate 632 away from the fixed base 54. This can limit the movement of the adjusting ring 63 along the axial direction of the fixed base 54 and maintain the stability of the connection between the adjusting ring 63, the frame 61, and the fixed base 54.

[0077] In the initial state, the first reset member 70 pushes the lens barrel 51 to slide to the end away from the fixed seat 54. A locking part 5111 near the fixed seat 54 engages with the first locking position 543 to restrict the rotation of the lens barrel 51 relative to the fixed seat 54 and maintain focus lock. When the lens barrel 51 is pushed towards the fixed seat 54 and the first locking position 543 is between the two locking parts 5111, a locking part 5111 away from the fixed seat 54 engages with the second locking position 631. At this time, rotating the lens barrel 51 allows it to rotate relative to the fixed seat 54 and drives the adjusting ring 63 to rotate synchronously. The adjusting ring 63 is restricted by the fixed seat 54 and cannot slide along the axis of the fixed seat 54. The frame 61 is also restricted by the fixed seat 54 and cannot rotate, causing the adjusting ring 63 to rotate relative to the frame 61. The first protrusion 62 slides along the spiral hole 630, causing the frame 61 to slide along the axis of the fixed seat 54, thereby adjusting the distance between the lens 52 and the light source 53.

[0078] Please refer to the following: Figures 1 to 3 The luminaire also includes a housing 10, a power supply 20, and a switch 30. The power supply 20 is installed inside the housing 10, and the housing 10 is connected to a mounting base 54. The switch 30 is electrically connected to the power supply 20 and the light source 53. The switch 30 can be used to control the light source 53, such as turning the light source 53 on and off. Optionally, the mounting base 54 is threadedly connected to the housing 10, thus facilitating the connection and disassembly of the light source assembly 50 from the housing 10.

[0079] In one embodiment of this application, please refer to Figure 1 , Figure 5 and Figure 6 A sliding seat 112 is slidably mounted on the housing 10. The sliding seat 112 is used for connection to an external connector. The lamp also includes a locking assembly 113 for locking the sliding seat 112. The external connector refers to the part that connects to the lamp, such as a bicycle, guide rail, vehicle, or headband. It can be connected to the sliding seat 112 by means of clips, screws, or magnets. The sliding seat 112 can slide on the housing 10 in a straight line or an arc. The sliding seat 112 can slide on the housing 10 to facilitate the adjustment of its position. After the position of the sliding seat 112 is adjusted, the locking assembly 113 can lock the position of the sliding seat 112 to maintain the stability of the lamp.

[0080] In one embodiment of this application, please refer to Figure 1 , Figure 5 and Figure 6 The housing 10 has a fourth groove 111 on one side for inserting an external connector, and a sliding seat 112 is slidably disposed at the bottom of the fourth groove 111. The external connector is connected by the cooperation of the fourth groove 111 and the sliding seat 112, which facilitates the adjustment of the lamp position and improves the stability of the lamp during installation.

[0081] In one embodiment of this application, please refer to Figure 1 , Figure 5 and Figure 6 The sliding seat 112 has a connecting hole 1121. Optionally, the connecting hole 1121 can be a screw hole, and the external connecting seat and the sliding seat 112 are connected by screws; or the connecting hole 1121 can be a snap-fit ​​hole, and the external connecting seat and the sliding seat 112 are snap-fitted by a snap-fit ​​component, such as a snap hook. In this way, a detachable connection between the sliding seat 112 and the external connecting seat can be achieved.

[0082] In one embodiment of this application, please refer to Figure 1 , Figure 5 and Figure 6 The sliding seat 112 has a second protrusion 1122, and the outer connecting seat has a recess. The second protrusion 1122 is used to engage with the recess of the outer connecting seat. The engagement of the second protrusion 1122 with the recess on the outer connecting seat facilitates alignment and helps prevent relative sliding between the outer connecting seat and the sliding seat 112, thus improving the stability of the connection between them. Alternatively, a screw can be used to connect the fittings through the connecting hole 1121, increasing the length of the second protrusion 1122 to accommodate different recess lengths on the outer connecting seat.

[0083] In one embodiment of this application, please refer to Figure 1 , Figure 5 and Figure 6 The sliding seat 112 is provided with multiple positioning grooves 1123, which are arranged along the length direction of the sliding seat 112. A locking component 113 engages with the positioning grooves 1123 to lock the position of the sliding seat 112. Thus, the sliding seat 112 can slide until different positioning grooves 1123 correspond to the locking component 113, thereby adjusting the position of the housing 10. The length direction of the sliding seat 112 is the same as the length direction of the fourth slide groove 111.

[0084] Optionally, the locking assembly 113 includes a rotating member 1131, a second reset member 1132, a locking plate 1133, and a connecting member 1134. The rotating member 1131 is rotatably mounted on the housing 10. The rotating member 1131 is provided with a locking block 1135, which is used to engage with the positioning groove 1123. The locking plate 1133 is used to lock the rotating member 1131. The connecting member 1134 connects the locking plate 1133 and the housing 10. The connecting member 1134 is used to release or lock the locking plate 1133. The second reset member 1132 is used to push the rotating member 1131 to reset. When the connecting piece 1134 releases the locking plate 1133, the locking plate 1133 releases the rotating piece 1131, which can push the sliding seat 112 to slide. When the sliding seat 112 is pushed, the sliding seat 112 can push the rotating piece 1131 to swing forward or backward, so that the adjacent positioning groove 1123 cooperates with the locking block 1135. When the locking block 1135 is engaged in the adjacent positioning groove 1123, the second reset piece 1132 can push the rotating piece 1131 to reset. At this time, the connecting piece 1134 is locked, and the locking plate 1133 can lock the position of the rotating piece 1131, thereby locking the position of the sliding seat 112 and the housing 10.

[0085] Optionally, the rotating member 1131 has a mating surface on the side near the locking plate 1133. When the connecting member 1134 locks the locking plate 1133, the locking plate 1133 engages with the mating surface to lock the rotating member 1131. The mating surface can be a flat surface or a serrated surface, etc. In this way, when the locking plate 1133 presses against the mating surface, the position of the rotating member 1131 can be locked.

[0086] Optionally, the locking plate 1133 forms a sidewall of the fourth slide groove 111 on the side near the rotating member 1131. When the connecting member 1134 releases the locking plate 1133, the fourth slide groove 111 can be opened to facilitate the release of the external connecting seat.

[0087] In one embodiment of this application, please refer to Figure 1 , Figure 5 and Figure 6 The housing 10 has a third sliding groove 1111, and the sliding seat 112 has a third protrusion 1124, which is slidably placed within the third sliding groove 1111. This guides the sliding direction of the sliding seat 112. Specifically, the third sliding groove 1111 is arranged along the length of the fourth sliding groove 111, and is located at the bottom of the fourth sliding groove 111.

[0088] Optionally, the third protrusion 1124 is located at one end of the sliding seat 112, and the end of the fourth sliding groove 111 away from the third protrusion 1124 is provided with a stop protrusion 114, which is used to stop the sliding seat 112. In this way, the sliding seat 112 can be prevented from sliding out of the end of the fourth sliding groove 111.

[0089] In one embodiment of this application, please refer to Figures 2 to 4 The lighting fixture also includes a transmission assembly 40; the transmission assembly 40 is used to press the switch 30, and the transmission assembly 40 is mounted 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 switch 30.

[0090] 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 touching operation of the switch 30. The operating end of the linkage assembly can be offset from the switch 30 to avoid excessive compression of the switch 30 when the housing 10 directly opposite the switch 30 is impacted. The power source 20 can be a battery or a power adapter that connects to an external circuit, such as a lithium battery or dry cell battery. The switch 30 can be a pressing or touching 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 to 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 component 40, which can be set inside the housing 10 or outside the housing 10. When the operating end of the transmission assembly 40 presses the switch member 30 at its output end, the limiting structure 120 can restrict further movement of the transmission assembly 40 after the switch member 30 is pressed at its output end, preventing the output end of the transmission assembly 40 from further pressing the switch member 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 member 30.

[0091] 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, it prevents further compression of the switch 30 when an external force impacts the transmission component 40. This helps prevent damage to the internal electronic switch or PCB board when the housing 10 of the lamp is impacted, thus improving the reliability of the lamp.

[0092] In one embodiment of this application, please refer to Figures 2 to 4The 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 free 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.

[0093] Optionally, the housing 10 has a through hole, and the support shaft 42 passes through the through hole; a sealing ring is fitted on the support shaft 42, and the sealing ring is used to seal the gap between the support shaft 42 and the inner wall of the through hole of the housing 10, so as to play a waterproof role.

[0094] In one embodiment of this application, please refer to Figures 2 to 4 The limiting structure 120 includes a second limiting groove, in which the actuating member 43 is placed. The second limiting groove is used to limit the swing angle of the actuating member 43. Thus, the second 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.

[0095] 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 limiting block controls the swing amplitude of the swing seat 41 when pressing the switch 30, preventing the swing seat 41 from excessively pressing the switch 30. Of course, in other embodiments, a second limiting groove can also be provided inside the housing 10 to limit the swing amplitude of the swing seat 41.

[0096] In another embodiment of this application, the support shaft 42 is provided with an adapter position, which may be a second 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.

[0097] Optionally, the support shaft 42 is connected to the middle of the swing seat 41 along the length direction, such as by screws.

[0098] In one embodiment of this application, the lamp further includes a third reset member for pushing the swing base 41 to reset. The third reset member is installed inside the housing 10, and its two ends are respectively connected to the housing 10 and the swing base 41. The third reset member may be a first spring or a first spring sheet, etc. After the toggle member 43 is pressed, the third reset member pushes the swing base 41 to separate from the switch member 30, thereby resetting the toggle member 43.

[0099] Optionally, a buffer block is provided on the swing seat 41 near the switch 30. The buffer block is an elastic body, such as a rubber block or a silicone block. This can prevent hard contact from damaging the switch 30 or the first circuit board 31.

[0100] 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.

[0101] Optionally, the power source 20 is a battery installed inside the housing 11, and the light source assembly 50 is installed at the other end of the housing 11. The cover 12 and the housing 11 can be connected by threads, screws, or snaps to cover and seal the end of the housing 11.

[0102] In one embodiment of this application, please refer to Figures 3 to 5 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.

[0103] In one embodiment of this application, please refer to Figures 3 to 5 The claw 13 is hinged to the cover 12 at its midpoint along the length direction. The lamp also includes a second elastic element 131 for pushing the claw 13 into the locking position 110. Optionally, the second 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.

[0104] In another embodiment of this application, please refer to Figure 13 and Figure 14 The cover 12 and the cylindrical shell 11 are connected by screws. In this way, the cover 12 and the cylindrical shell 11 can be detachably connected.

[0105] In one embodiment of this application, please refer to Figures 1 to 3The lamp also includes a first circuit board 31 electrically connected to the power supply 20. One side of the first circuit board 31 is attached to the bottom of the cover 12, and the switch 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 30 away from the first circuit board 31. In this way, the connection position between the switch 30 and the first circuit board 31 can be kept stable when the transmission assembly 40 presses the switch 30, preventing the switch 30 and the first circuit board 31 from shifting under pressure. Specifically, the swing seat 41 is located on the side of the switch 30 away from the first circuit board 31, which can support the first circuit board 31 using the bottom plane of the cover 12, which is beneficial for heat dissipation of the first circuit board 31 and prevents the first circuit board 31 from being damaged when pressed.

[0106] Optionally, one end of the first circuit board 31 connected to the switch 30 rests against the bottom of the cover 12, and the other end of the first circuit board 31 is electrically connected to the power supply 20 and the light source assembly 50. This allows the switch 30 to be conveniently positioned at the bottom of the cover 12, and facilitates the other end of the first circuit board 31 to extend out of the cover 12 for electrical connection with the power supply 20. The first circuit board 31 can be a flexible board or a rigid board.

[0107] Optionally, a pressure seat 14 is installed inside the cover 12, and the pressure seat 14 abuts against the end of the first circuit board 31 near the switch 30, pressing one end of the first circuit board 31 against the bottom of the cover 12; a pressure plate 15 is detachably installed at the end of the cover 12 near the cylindrical shell 11, and the pressure plate 15 is used to fix the pressure seat 14. In this way, the positions of the switch 30 and the first circuit board 31 can be kept stable.

[0108] Optionally, the first circuit board 31 has a positioning hole at one end near the switch 30, and the bottom of the cover 12 has a positioning block that is inserted into the positioning hole. This helps to keep the first circuit board 31 stable at the bottom of the cover 12, so as to facilitate the alignment of the switch 30 and the swing seat 41.

[0109] In one embodiment of this application, please refer to Figures 2 to 4 A mounting plate 211 is installed at one end of the cylindrical shell 11 near the cover 12. A second circuit board 21 is mounted on the mounting plate 211. The second circuit board 21 is electrically connected to the battery and the first circuit board 31. This facilitates connection with the battery.

[0110] Optionally, the second circuit board 21 has a conductive spring or conductive contact piece on the side away from the cover 12 that abuts against the battery, and a terminal block on the other side of the second circuit board 21 that is detachably connected to the first circuit board 31; the first circuit board 31 is electrically connected to the light source assembly 50 through the second circuit board 21 and the terminal block. In this way, the battery electrical connection can be kept stable, and the disassembly of the first circuit board 31 and the second circuit board 21 and the circuit arrangement can be facilitated.

[0111] Optionally, please refer to Figure 2 A third circuit board 22 is mounted on one end of the mounting base 54 near the housing 10.
