DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0024] like Figures 1 to 5 As shown, the utility model provides an easy-to-assemble lens module, comprising a base 1, a shell 2 and a lens assembly 3, wherein the shell 2 is mounted on the base 1, and the lens assembly 3 is mounted between the base 1 and the shell 2; a first protrusion 11 is provided on one side of the base 1, and a second protrusion 21 is provided on one side of the shell 2;

[0025] When the housing 2 is mounted on the base 1 , the first protrusion 11 and the second protrusion 21 abut against each other; the first protrusion 11 and the second protrusion 21 cooperate to form a stopper 4 assembled to an external component.

[0026] In actual use, the base has a wiring hole 14 for guiding the wires (not shown in the figure) of the lens assembly 3, and the housing 2 has a lens hole 26 for allowing the lens assembly 3 to shoot the outside world.

[0027] Specifically, after the lens assembly 3 is assembled to the base 1, it is assembled to the base 1 through the shell 2 so that the lens assembly 3 is located between the base 1 and the shell 2 to achieve the protection effect of the lens assembly 3; after the base 1 and the shell 2 are assembled, the first protrusion 11 and the second protrusion 21 abut against each other to form a limiter 4, which not only serves to position the camera assembled to the outside world, but also is used to achieve the positioning and alignment effect between the base 1 and the shell 2, that is, to allow the base 1 and the shell 2 to be assembled to each other in a suitable posture.

[0028] The camera using the present invention does not need to be provided with a bracket inside, but only needs to be provided with a hole for accommodating the present invention and a slot for accommodating the limiter 4. The simple structure can ensure the installation effect and further reduce the size of the camera.

[0029] In this embodiment, hollow grooves 5 are respectively provided between the first protrusion 11 and the base 1 and between the second protrusion 21 and the housing 2, and the two hollow grooves 5 are connected to each other. The hollow grooves 5 can be provided with corresponding latches to achieve a positioning effect, or the latches can be not provided and only used for positioning, so that the hollow grooves 5 can be provided to reduce raw materials and further save costs.

[0030] Specifically, the cross-sectional shapes of the first protrusion 11 and the second protrusion 21 are respectively rectangular; the first protrusion 11 is integrally formed with the base 1 , and the second protrusion 21 is integrally formed with the housing 2 .

[0031] In this embodiment, the inner side wall of the base 1 is provided with a plurality of positioning grooves 12 , and one end of the housing 2 inserted into the base 1 is provided with a plurality of positioning members 22 , and the positioning grooves 12 and the positioning members 22 are assembled in a one-to-one correspondence.

[0032] By inserting the positioning member 22 into the positioning groove 12, the base 1 and the housing 2 are assembled so that the relative posture of the base 1 and the housing 2 is maintained, thereby improving the assembly efficiency.

[0033] In this embodiment, the base 1 is provided with a limit stop ring 13, and the positioning member 22 is provided with a guide slope 23, which is used to guide the positioning member 22 to slide into the positioning groove 12 along the limit stop ring 13, and the limit stop ring 13 is used to prevent the positioning member 22 from detaching from the positioning groove 12 after the positioning member 22 is assembled into the positioning groove 12.

[0034] That is, the limit stop ring 13 blocks the top of the positioning groove 12. When the base 1 and the shell 2 are assembled, the guide bevel 23 of the positioning member 22 first contacts the limit stop ring 13 to guide the limit member 4 to bend into the guide bevel 23 until the guide bevel 23 is no longer in contact with the limit stop ring 13. The positioning member 22 then restores its shape and is inserted into the positioning groove 12, so that the base 1 and the shell 2 can be assembled and fixed. Since the positioning member 22 is inserted into the positioning groove 12 after restoring its shape, the limit stop ring 13 prevents the positioning member 22 from detaching from the positioning groove 12 based on the stopping effect of the limit stop ring 13, thereby ensuring the stability of the assembly between the base 1 and the shell 2 and avoiding the separation of the two.

[0035] In this embodiment, the lens assembly 3 has a limiting mounting member 31, the cross-sectional shape of the limiting mounting member 31 is a polygonal structure, the mounting limiting member 4 is provided with n limiting edges 32 and n non-limiting edges 33, and a non-limiting edge 33 is provided between two adjacent limiting edges 32;

[0036] The inner side wall of the housing 2 is provided with n limiting structures 24 , and the n limiting structures 24 are arranged in a one-to-one correspondence with the n limiting edges 32 .

[0037] Specifically, the limiting structure 24 includes two limiting ribs 25 arranged at intervals, and the limiting ribs 25 conflict with the limiting edges 32. The utility model achieves the positioning effect of the lens assembly 3 by the limiting ribs 25 conflicting with the limiting edges 32, ensuring that the lens assembly 3 will not rotate relative to the housing 2 when in the housing 2.

[0038] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
