[0030] Please refer to Figures 1 to 8 The embodiment of the utility model provides a filter mounting structure, which comprises a lens holder 1, two groups of opposite side one 2 and side two 3 are arranged on the lens holder 1, the side one 2 and the side two 3 form a rectangular mounting groove, and a sensor is installed in the mounting groove. In order to quickly install the filter body 13, the fixed plate 10 is respectively clamped on the upper side of the two side one 2, and the filter body 13 is fixed between the two groups of fixed plates 10.

[0031] The fixed groove 7 is formed in the upper side of the side one 2, and the lower side of the fixed plate 10 is clamped in the fixed groove 7. The filter body 13 can be quickly and accurately fixed on the upper side of the sensor, and the efficiency of installing the filter body 13 is improved.

[0032] A plurality of springs 8 are arranged in the fixed groove 7, the lower side of the fixed plate 10 is attached to the spring 8, when the fixed plate 10 is clamped in the fixed groove 7, the spring 8 is extruded downward, the spring 8 is contracted under stress, and the spring 8 can promote the fixed plate 10 to quickly move out of the fixed groove 7 when the filter body 13 is disassembled.

[0033] Therefore, in order to keep the fixing plate 10 stable when it is clamped in the fixing groove 7, the fixing plate 10 is fixed in the side edge one 2 by the positioning assembly, specifically, the positioning assembly includes an external positioning piece 14, both sides of the external positioning piece 14 are symmetrically provided with an extension plate 15, the extension plate 15 penetrates the through groove 11 on the upper side of the fixing plate 10, since the outer side of the side edge one 2 is provided with a bolt 9, the bolt 9 is threaded through the extension plate 15 and the threaded hole 12 of the fixing plate 10 to be screwed, thereby fixing the external positioning piece 14 and the fixing plate 10.

[0034] In addition, the positioning plate 4 is symmetrically arranged on the side edge two 3, the inner side of the positioning plate 4 is provided with a clamping groove 5, the clamping block 18 arranged on both sides of the external positioning piece 14 is clamped and matched with the clamping groove 5, one side of the clamping groove 5 is provided with a convex groove 6, one side of the clamping block 18 is provided with a convex block 19, the convex block 19 is clamped and matched with the convex groove 6, thereby enhancing the stability of the external positioning piece 14.

[0035] Further, the side plate 17 is arranged on the other two sides of the external positioning piece 14, the camera assembly 20 is located between the two side plates 17, the annular sleeve 16 is arranged inside the two side plates 17, the annular sleeve 16 is clamped with the lower end of the camera assembly 20, thereby making the light filter body 13 can accurately correspond to the camera assembly 20.

[0036] On the other hand, the application also provides a light filter of the light filter mounting structure, including a light filter body 13, two groups of fixing plates 10 are respectively pasted on both sides of the light filter body 13 by glue.

[0037] In summary, the working principle of the filter mounting structure and the filter according to the embodiments of the present application is as follows: two groups of the fixing plates 10 are respectively pasted to the two sides of the filter body 13 by means of glue, the lower side of the fixing plate 10 to which the filter body 13 is pasted is aligned with the fixing groove 7 on the side edge one 2, and the fixing plate 10 is clamped into the fixing groove 7. At this time, the fixing plate 10 will extrude the spring 8 in the fixing groove 7 downward, so that the spring 8 is retracted, thereby providing elastic force assistance for subsequent disassembly. The extension plate 15 of the external positioning member 14 is inserted through the through groove 11 on the upper side of the fixing plate 10, so that the external positioning member 14 can stably support the fixing plate 10. The bolt 9 is inserted through the threaded holes 12 on the extension plate 15 and the fixing plate 10, and the external positioning member 14 and the fixing plate 10 are firmly fixed together by means of threaded connection, so that the filter body 13 cannot be easily displaced. The clamping blocks 18 arranged on the two sides of the external positioning member 14 are clamped with the clamping grooves 5 on the inner side of the positioning plate 4 on the side edge two 3, and the protrusions 19 on one side of the clamping blocks 18 are matched with the protruding grooves 6 on one side of the clamping grooves 5, so as to further enhance the stability of the external positioning member 14. The side plates 17 arranged on the other two sides of the external positioning member 14 are located between the camera assemblies 20, and the annular sleeves 16 in the side plates 17 are clamped with the lower ends of the camera assemblies 20, so as to ensure the accurate correspondence between the filter body 13 and the camera assemblies 20, thereby realizing the correct arrangement of the optical path. After the above steps, the filter body 13 has been quickly and accurately mounted above the sensor, and the entire mounting structure is stable and reliable, does not affect the function of the image sensor, and is convenient for subsequent disassembly and maintenance work. When the filter needs to be disassembled, the bolt 9 is loosened, the external positioning member 14 is taken out, and then the fixing plate 10 together with the filter body 13 can be easily ejected from the fixing groove 7 by means of the elastic force of the spring 8 in the fixing groove 7, so that the quick disassembly is completed.
