It is understood that the position avoiding hole 111 is used for lens penetration, so that the light entering the lens 12 can further exit out of the housing 11. The profiling fixing position 131 is used for accommodating and positioning the lens 12, preferably, the profile of the profiling fixing position 131 is matched with the profile of the lens 12, so that the lens 12 can be just accommodated and positioned in the profiling fixing position 131, and the installation accuracy of the lens 12 is improved; further preferably, the bottom of the profile fixing position 131 may be provided with a top holding surface, which has the same specification as the profile or slope of the surface of the lens 12 adjacent to the bracket 13, so that the lens 12 can be further limited after being accommodated in the profile fixing position 131, thereby further improving the installation accuracy of the lens 12.

As shown in fig. 3 to 9, the bracket 13 may include a body 13a, at least one limiting member 132, at least one elastic member 133, and a sliding rail mechanism 14, wherein the at least one limiting member 132 and the at least one elastic member 133 are disposed on the body 13a, and the sliding rail mechanism 14 is used for guiding the body 13a to slide;

the at least one limiting member 132 and the at least one elastic member 133 define a profiling fixing position 131 on the body together; the body 13a can move towards the direction close to or away from the lens 12 under the guidance of the slide rail mechanism 14, and the elastic member 133 can deform under the support of the lens 12 to open the profile fixing position 131, so that the lens 12 can be inserted into the profile fixing position 131. When the edge of the lens 12 abuts against the stopper 132, the elastic member 133 is elastically restored by being disengaged from the abutment of the lens 12, so that the lens 12 is positioned in the profile fixing position 131 in the sliding direction of the body 13 a.

It can be understood that the body 13a also has the function of pressing and holding the lens 12, and the lens 12 is located on the body 13a on the one hand and is fixed at the predetermined installation position by the pressing and holding of the body 13a on the other hand; each limiting member 132 and each elastic member 133 are located on the body 13a, and each limiting member 132 and each elastic member 133 are used for limiting the lens 12 in the profiling fixing position 131; preferably, the limiting member 132 and the elastic member 133 can position the lens 12 from two positions; more preferably, the limiting member 132 and the elastic member 133 can position the lens 12 from three different positions; more preferably, the position-limiting member 132 and the elastic member 133 can position the lens 12 from four different positions. Of course, the number of the limiting members 132 and the number of the elastic members 133 can be flexibly adjusted, and is preferably adapted to the surface profile of the lens and to the effective positioning of the lens 12.

It is also understood that the elastic member 133 has a certain elasticity, and the elastic member 133 may be configured as a spring, and may also be configured as other structures or components having elastic resetting capability in the related art. The limiting member 132 may be configured as a spring, a limiting wall, a limiting protrusion, or other structure or component capable of limiting in the related art. The slide rail mechanism 14 may be a slide connection mechanism such as a slide rail mechanism or a slide groove mechanism, and may also be a slide structure such as a slide channel, as long as the slide structure can guide the support 13 to slide along a predetermined track relative to the lens 12, and the predetermined slide track may be flexibly set, and may be a straight line, a curved line, an irregular line, or the like.

In particular, a detachable connection mechanism may be further disposed on the bracket 13, so that the bracket 13 is detachably disposed at a predetermined position, and after the bracket 13 is disposed at the predetermined position, the bracket 13 can be further slid by the slide rail mechanism 14, thereby completing the assembly of the lens 12 and the bracket 13.

Preferably, the elastic member 133 may be configured to: when the holder 13 slides in a predetermined direction, the lens 12 can smoothly bend against the elastic member 133, and after the lens 12 is positioned and the elastic member 133 is restored, the holder 13 does not compress the elastic member 133 regardless of the direction in which it moves.

It can be understood that, with the present preferred embodiment, the lens entering the copying fixing station 131 can be prevented from coming off the holder 13, improving the mounting reliability. Of course, the elastic member 133 can also be configured to be compressed only when a certain amount of force is required to drive the support 13 and the lens 12 to move relatively, so as to complete the disassembly of the lens 12 and the support 13, and thus, the elastic member can be applied to an application scenario that requires the rapid disassembly of the lens 12 and the support 13.

As shown in fig. 4 to 7, the body 13a may be provided with a first surface 131a and a second surface 132a in some embodiments, the profiling fixing position 131 is located on the first surface 131a, and the second surface 132a is used for mounting a light source; light from the light source may be directed onto lens 12.

It will be appreciated that the first surface 131a and the second surface 132a are preferably opposite sides of the body 13a, so that a linearly propagating light source can be directed onto the lens 12. The light source can be an LED lamp bead or other components capable of emitting light rays in the related technology; the number of the light sources can be one or a plurality of light sources, and the light sources can be arranged at intervals, closely, radially or randomly.

As shown in fig. 6 to 9, the at least one elastic member 133 may include two elastic members 133 in some embodiments, the lateral sides of the two elastic members 133 are each bent to extend into a contoured surface 1334 adapted to the edge of the lens 12, and the contoured surface 1334 is used for abutting against the edge of the lens 12.

It is understood that the number of the elastic members 133 may be two, and the two elastic members 133 may be spaced apart or closely arranged; preferably, the two elastic members 133 are symmetrically disposed, and the lens 12 is fixed from two symmetrical positions, respectively, so that the installation stability of the lens 12 can be improved. The contoured surface 1334 may be a plane, a curved surface or an irregular surface, and the contoured surfaces 1334 on the respective springs 133 may be the same or different, and are preferably adapted to the contour of the lens 12, so as to ensure the mounting stability of the lens 12.

As shown in fig. 6 to 9, the elastic member 133 may include a connecting portion 1331 disposed on the body 13a and a protruding portion 1332 disposed on the connecting portion 1331, wherein the thickness of the protruding portion 1332 gradually decreases towards a direction away from the profiling fixing position 131 to form a guiding curved surface 1333, and the lens 12 is configured to slidably abut against the guiding curved surface 1333 to bend and deform the connecting portion 1331.

It is understood that the connection portion 1331 has a certain elasticity, and a hole or a groove may be formed on the body 13a to provide a deformation space for the connection portion 1331; the protrusion 1332 is used to position the lens 12, and the guiding curved surface 1333 on the protrusion 1332 is used to guide the protrusion 1332 to bring the connecting portion 1331 into compression.

It can be understood that, during the sliding process of the support 13, the lower position on the guiding curved surface 1333 contacts the lens 12 first, that is, the position with smaller thickness on the protruding portion 1332 contacts the lens 12 first, so that the edge of the lens 12 can smoothly fall onto the guiding curved surface 1333, and it is avoided that, during the positioning process of the lens 12, the support at the edge of the lens 12 is stuck outside the protruding portion 1332 to cause the connecting portion 1331 to be unable to bend, and it is ensured that the profiling fixing position 131 can be opened for the lens 12 to enter when the support 13 slides along the predetermined direction, thereby further improving the installation efficiency of the lens;

accordingly, the lens 12 that is pulled out from the higher position of the guiding curved surface 1333 will not push against the protruding portion 1332 any more, so that the connecting portion 1331 drives the protruding portion 1332 to reposition, and the edge of the lens 12 that enters the profiling fixing position 131 will be hard to enter the higher position of the guiding curved surface 1333, that is, the position with larger thickness on the protruding portion 1332.

The higher position of the guiding curved surface 1333 does not absolutely mean the position of the raised portion 1332 with a larger thickness, and the lens is positioned and is difficult to be removed from the profiling fixing position 131; similarly, the lower position of the guiding curved surface 1333 is not absolutely the position where the thickness on the protruding portion 1332 is small.

As shown in fig. 6 to 9, the at least one limiting member 132 may include, in some embodiments, a first limiting edge 1321 and a second limiting edge 1322 both disposed on the body 13 a;

It is understood that the first limiting edge 1321 and the second limiting edge 1322 may be disposed at intervals, or they may be directly connected to each other; the first limiting edge 1321 and the second limiting edge 1322 are symmetrically arranged, so that the lens 12 can be positioned from two symmetrical positions, and the mounting stability of the lens 12 is improved.

It will also be appreciated that either or both of the first limiting edge 1321 and the second limiting edge 1322 can be substantially linear or curvilinear.

As shown in fig. 7 to 9, the body 13a may be formed with an insertion notch 134 communicating with the profiling fixing position 131 in some embodiments, the insertion notch 134 is used for inserting the lens 12, and the elastic member 133 is exposed between the insertion notch 134 and the profiling fixing position 131;

it can be understood that the insertion notch 134 is used to guide the lens 12 to align with the copying fixing position 131, and at the same time, provides a space for the lens 12 to enter the copying fixing position 131, so as to prevent the lens 12 from being stuck to the edge of the body 13a and being unable to be installed smoothly.

Preferably, the bottom of the insertion notch 134 may be provided with a slope to guide the lens 12 to smoothly enter the insertion notch 134 at a lower position and gradually move to a matching height or inclination of the profile fixing position 131, etc., to further improve the mounting accuracy.

As shown in fig. 5, 8 and 9, the lens 12 may include a base 121 and a convex mirror 122 in some embodiments; the bottom plate 121 is used for being inserted into and fixed in the copying fixing position 131, and the convex mirror 122 is used for guiding light rays to be emitted along a preset track.

It is understood that the bottom plate 121 can also be jammed in the housing 11 to prevent the lens 12 from directly escaping from the clearance hole 111. The convex mirror 122 is used for guiding the light from the bottom plate 121 and emitting the light in a predetermined direction.

It can be understood that the convex mirror 122 penetrates through the avoiding hole 111 and is exposed outside the housing, so that the light emitted through the convex mirror 122 can be projected to the outside of the housing.

The power source 16 is used for supplying power, and the power source 16 may be a battery, preferably a rechargeable lithium battery. The positioning columns 135 and the positioning holes 151 are used for positioning the relative positions of the body 13a and the lamp panel 15.
