The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0031] like Figures 1 to 4 As shown, a detachable self-resetting assembly 10 of an embodiment includes a self-resetting elastic pressing member 100, an annular stopper 200, a housing 300, a reflector 400 and a reflective sheet 500. The reflector 400 is provided with a light exit hole 410, the reflector 400 is snap-connected to the inner wall of the housing 300, and the reflective sheet 500 is movably covered on the light exit hole 410. Further, the reflective sheet 500 is arranged on the self-resetting elastic pressing member 100, the first end of the self-resetting elastic pressing member 100 is connected to the reflector 400, and the second end of the self-resetting elastic pressing member 100 is elastically movably arranged on one side of the reflector 400.

[0032] It can be understood that, since the reflective sheet 500 is movably covered on the light exit hole 410 of the reflector 400, and the reflective sheet 500 is arranged on the self-resetting elastic pressing member 100, the reflective sheet 500 can close and open the light exit hole 410, so that the self-resetting elastic pressing member 100 can press the reflective sheet 500 on the light exit hole 410 of the reflector 400; and since the first end of the self-resetting elastic pressing member 100 is connected to the reflector 400, and the second end of the self-resetting elastic pressing member 100 is elastically movably arranged on one side of the reflector 400, the first end of the self-resetting elastic pressing member 100 can be fixed on the reflector 400, and the reflector 400 is installed. When the reflector 400 is removed, the operator only needs to press the reflective sheet 500 inwardly, and the second end of the self-resetting elastic pressing member 100 will shrink inwardly, so that a gap is exposed between the reflective sheet 500 and the light outlet hole 410. The reflector 400 can be removed by pulling it outward through the gap. After the reflector 400 is removed, the shrinking second end of the self-resetting elastic pressing member 100 will automatically reset, so that the reflective sheet 500 will be pressed against the light outlet hole 410 of the reflector 400 again, so that the reflector 400 is easy to disassemble and assemble and the reflective sheet 500 can be automatically reset, thereby improving the efficiency of disassembling and assembling the reflector 400.

[0033] Furthermore, the reflective sheet 500 is a reflective glass sheet, which has good optical properties and a relatively hard and wear-resistant surface, thereby reducing the number of replacements and maintenance costs.

[0034] Furthermore, the reflector 400 is provided with an elastic barb buckle on the outer peripheral wall away from the light exit hole 410, and the elastic barb buckle is used to snap into the inner wall of the shell 300. Through the additional elastic barb buckle, the operator can directly press the reflector toward the inner wall of the shell 300, and the reflector can be snapped into the inner wall of the shell 300 under the action of elasticity, which simplifies the installation of the reflector and thus improves the installation efficiency.

[0035] Furthermore, the self-resetting elastic pressing member 100 is detachably connected to the reflector 400 to ensure the convenience of replacing the self-resetting elastic pressing member 100 .

[0036] Furthermore, in one embodiment, an annular stopper 200 is protruded from the inner wall of the outer shell 300, a first end of the self-resetting elastic pressure member 100 abuts against the annular stopper 200, and a second end of the self-resetting elastic pressure member 100 is elastically and movably arranged on one side of the reflector 400, so that the reflective sheet is elastically pressed to cover the light exit hole 410.

[0037] like Figure 2 and Figure 3As shown, in one embodiment, the self-resetting elastic pressure member 100 includes a pressure ring 110 and a fixed elastic ring 120 that are elastically connected, that is, the fixed elastic ring 120 is elastically connected to the pressure ring 110, the pressure ring 110 is tiltedly arranged on the fixed elastic ring 120, the pressure ring 110 forms a limited position clamping groove 111, the reflective sheet 500 is arranged in the limited position clamping groove 111, and the fixed elastic ring 120 is fixedly connected to the reflector 400. In this embodiment, the fixed elastic ring 120 is detachably connected to the reflector 400.

[0038] It can be understood that since the clamping ring 110 is tiltedly arranged on the fixed elastic ring 120, an angle is formed between the clamping ring 110 and the fixed elastic ring 120, which can ensure the elastic activity between the clamping ring 110 and the fixed elastic ring 120, so that the clamping ring 110 can be automatically reset under the action of the fixed elastic ring 120; and since the reflective sheet 500 is arranged in the limiting snap-fit ​​groove 111, when the clamping ring 110 is reset, the reflective sheet 500 is automatically reset along with the clamping ring 110, that is, the reflective sheet 500 is automatically reset to press and cover the light outlet hole 410.

[0039] In one embodiment, the preset angle of inclination between the clamping ring 110 and the fixed elastic ring 120 is 20° to 25°. It can be understood that since the preset angle of inclination between the clamping ring 110 and the fixed elastic ring 120 is 20° to 25°, a more appropriate elastic restoring force is provided to ensure that the clamping ring 110 can be automatically reset after being subjected to external force and the action of the fixed elastic ring 120, thereby improving the efficiency and stability of the automatic reset, thereby improving the efficiency of the automatic reset of the reflective sheet 500 of the reflector 400.

[0040] In one embodiment, the fixed elastic ring 120 includes an elastic ring body 122 and a first elastic fixing portion 123 and a second elastic fixing portion 124 respectively protruding from both ends of the elastic ring body 122, the first elastic fixing portion 123 is connected to the first connecting position of the clamping ring 110, the second elastic fixing portion 124 is connected to the second connecting position of the clamping ring 110, and an inclined preset angle is formed between the plane where the elastic ring body 122 is located and the plane where the clamping ring 110 is located, and the elastic ring body 122 is detachably connected to the reflector 400. It can be understood that by providing the first elastic fixing portion 123 and the second elastic fixing portion 124 which are respectively connected to the first connecting position and the second connecting position of the clamping ring 110, the firmness of the connection between the fixed elastic ring 120 and the clamping ring 110 is improved; due to the detachable connection between the elastic ring body 122 and the reflector 400, it is convenient to replace the self-resetting elastic clamping piece 100; and since a preset inclined angle is formed between the plane where the elastic ring body 122 is located and the plane where the clamping ring 110 is located, it is ensured that the clamping ring 110 can be automatically reset when subjected to external force and under the action of the first elastic fixing portion 123 and the second elastic fixing portion 124.

[0041] Furthermore, the line connecting the first connection position and the second connection position passes through the center of the clamping ring 110, that is, the first connection position and the second connection position are located at two ends of the clamping ring 110 with a center angle of 180°. It can be understood that since the first connection position and the second connection position are located at two ends of the clamping ring 110 with a center angle of 180°, under the action of the fixed elastic ring 120, the clamping ring 110 can more evenly bear the force at both ends of the fixed elastic ring 120, thereby achieving a more stable clamping and resetting effect.

[0042] In one embodiment, the detachable self-resetting assembly 10 further includes a position-limiting mounting portion, which is disposed at the periphery of the clamping ring 110 and is used for position-limiting mounting of the reflective sheet 500. It can be understood that the additional position-limiting mounting portion improves the accuracy of the installation of the reflective sheet 500, can effectively limit the position of the reflective sheet 500, and avoids position deviation during the installation process. In addition, the detachable design facilitates the replacement and maintenance of the reflective sheet 500, and reduces the maintenance cost and difficulty.

[0043] like Figure 3 As shown, further, in one embodiment, the position-limiting installation portion includes a plurality of position-limiting baffles 600, and the plurality of position-limiting baffles 600 are arranged at intervals on a side of the clamping ring 110 adjacent to the reflector 500, each position-limiting baffle 600 abuts against the outer peripheral wall of the reflector 500, and each position-limiting baffle 600 and the position-limiting engaging groove 111 jointly position-limit the reflector 500. It can be understood that the plurality of position-limiting baffles 600 restrict the reflector 500 from different directions, thereby improving the stability of the installation, and working together with the position-limiting engaging groove 111, provide a precise installation position for the reflector 500, ensure that the reflector 500 is firmly installed on the clamping ring 110, and when the reflector 400 is disassembled and assembled, the problem of the reflector 500 falling off is avoided, thereby improving the efficiency of disassembling and assembling the reflector 400.

[0044] In one of the embodiments, the clamping ring 110 is welded to the fixed elastic ring 120 to ensure the firmness of the connection between the clamping ring 110 and the fixed elastic ring 120, to ensure that the clamping ring 110 and the fixed elastic ring 120 have a certain strength during elastic deformation, and to reduce the breakage or deformation of the clamping ring 110 and the fixed elastic ring 120 during use.

[0045] In one embodiment, the clamping ring 110 is a stainless steel clamping ring 110, a titanium alloy clamping ring 110, or an aluminum bronze clamping ring 110. It can be understood that since stainless steel, titanium alloy, and aluminum bronze have good elasticity and high strength, the clamping ring 110 is ensured to maintain a stable reset and clamping ability during repeated use, and is not prone to breakage or deformation.

[0046] Similarly, in one embodiment, the fixed elastic ring 120 is a stainless steel fixed elastic ring 120, a titanium alloy fixed elastic ring 120, or an aluminum bronze fixed elastic ring 120. It can be understood that since stainless steel, titanium alloy, and aluminum bronze have good elasticity and high strength, they can provide good elasticity, ensuring that the fixed elastic ring 120 maintains stable elastic properties during repeated use and is not prone to breakage or deformation.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the detachable self-resetting assembly 10 further includes a fixing member 800, a fixing elastic ring 120 is provided with a mounting hole 121, and a fixing hole 420 is provided at the end of the reflector 400 adjacent to the fixing elastic ring 120, and the fixing member 800 is connected to the fixing hole 420 through the mounting hole 121. It can be understood that the connection of the fixing member 800 provides a reliable fastening force, ensures a stable connection between the fixing elastic ring 120 and the reflector 400, and prevents loosening during use. The connection of the fixing member 800 is convenient for disassembly and assembly when the self-resetting elastic pressing member 100 needs to be replaced, thereby improving the efficiency of replacement. In this embodiment, the fixing hole 420 is a threaded hole, and the fixing member 800 is a screw. A fixing column is convexly provided at the end of the reflector 400 adjacent to the fixing elastic ring 120, and the fixing hole 420 is opened in the fixing column. In other embodiments, the fixing hole 420 is a clamping hole, the fixing member 800 is a buckle, and the mounting hole 121 is opened in the elastic ring body 122.

[0048] In one embodiment, the detachable self-resetting assembly 10 further includes a sealing ring 700, which is disposed between the reflector 500 and the reflector 400, and the reflector 500 abuts against the end surface of the reflector 400 through the sealing ring 700. It can be understood that the additional sealing ring 700, on the one hand, improves the waterproof performance and effectively prevents moisture from penetrating into the interior of the anti-fog lamp 1 from the fitting surface of the reflector 500 and the reflector 400, and on the other hand, improves the sealing effect and fills the small gap between the fitting surfaces, ensuring a tighter seal and preventing dust from entering the interior of the anti-fog lamp 1.

[0049] The present disclosure further provides an anti-fog lamp 1, comprising the detachable self-resetting assembly 10 described in any one of the above embodiments.

[0050] Compared with the prior art, the present invention has at least the following advantages:

[0051] Since the reflective sheet 500 is movably covered on the light-emitting hole 410 of the reflector 400, and the reflective sheet 500 is arranged on the self-resetting elastic pressing member 100, the reflective sheet 500 can close and open the light-emitting hole 410, so that the self-resetting elastic pressing member 100 can press the reflective sheet 500 on the light-emitting hole 410 of the reflector 400; and since the first end of the self-resetting elastic pressing member 100 is connected to the reflector 400, and the second end of the self-resetting elastic pressing member 100 is elastically movably arranged on one side of the reflector 400, so that the first end of the self-resetting elastic pressing member 100 can be fixed on the reflector 400, when the reflector 400 is installed, The reflector 400 is directly connected to the inner wall of the shell 300 inwardly. When disassembling, the operator only needs to press the reflective sheet 500 inwardly, and the second end of the self-resetting elastic pressing member 100 shrinks inwardly, so that a gap is exposed between the reflective sheet 500 and the light outlet hole 410. The reflector 400 can be removed by pulling it outward through the gap. After removing the reflector 400, the shrinking second end of the self-resetting elastic pressing member 100 is automatically reset, so that the reflective sheet 500 is again against the light outlet hole 410 of the reflector 400, so that the reflector 400 is easy to disassemble and assemble and the reflective sheet 500 can be automatically reset, thereby improving the efficiency of disassembling and assembling the reflector 400.

[0052] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
