[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figure 1 as well as Figure 2A lens assembly of a camera, comprising a camera housing 1, a lens 2 and a foam member 3, wherein the foam member 3 is arranged between the camera housing 1 and the lens 2, and the foam member 3 comprises a first strong adhesive 31, a foam 32, a weak adhesive 33, a film 34 and a second strong adhesive 35 which are arranged in sequence, the film 34 comprises a connected bonding portion and a tearing portion 341, and opposite sides of the bonding portion are respectively bonded to the weak adhesive 33 and the second strong adhesive 24, the first strong adhesive 31 is bonded to the camera housing 1, and the second strong adhesive 24 is bonded to the lens 3.

[0024] The structural principle of the utility model is briefly described as follows: the lens 2 assembly described in the utility model has a high viscosity of the first strong adhesive 31 and the second strong adhesive 35, and a low viscosity of the weak adhesive 33. In actual application, the foam piece 3 is bonded to the camera housing 1 through the first strong adhesive 31, and the foam piece 3 is bonded to the lens 2 through the second strong adhesive 35. During the bonding process, in order to ensure the reliability of the bonding of the lens 2, the lens 2 needs to be pressure-maintained. At this time, the foam 32 located between the lens 2 and the camera housing 1 can play a buffering role for the lens 2 and the camera to prevent the lens 2 from being crushed; the film The outer contour of the bonding portion of 34 extends to the side away from the bonding portion to form a tearing portion 341, and the tearing portion 341 protrudes from the outer contour of the lens 2. When the lens 2 needs to be removed from the camera housing 1 for cleaning, due to the low viscosity of the weak adhesive 33, the operator can pull the tearing portion 341 on the film 34 to destroy the weak adhesive 33 between the film 34 and the foam 32, so that the bonding portion of the film 34 is separated from the foam 32, thereby making the first strong adhesive 31 and the foam 32 adhere to the camera housing 1, and the film 34, the second strong adhesive 35 and the lens 2 are removed from the camera housing 1.

[0025] From the above description, it can be seen that the beneficial effect of the utility model is that: the lens 2 assembly described in the utility model, the lens 2 is bonded to the camera housing 1 through the foam part 3. In actual application, the operator can pull the film 34 through the tearing part 341 to separate the film 34 from the foam 32, thereby removing the film 34 together with the lens 2 from the camera housing 1. The lens 2 assembly is convenient for the operator to clean the lens 2. This lens 2 assembly can reduce the difficulty of disassembling the lens 2 of the camera, and the lens 2 will not be damaged during the disassembly process. The lens 2 assembly can reduce the cost of cleaning and maintenance of the camera.

[0026] Furthermore, a side of the film 34 close to the weak adhesive 33 is provided with a smooth surface, and a side of the film 34 close to the second strong adhesive 35 is provided with a frosted surface.

A granular structure is formed on the frosted surface of the film 34, which makes the contact area between the second strong adhesive 35 larger, thereby increasing the adhesive force between the second adhesive and the film 34, and ensuring that the film 34 and the weak adhesive 33 are separated first during the process of disassembling the lens 2, so that the film 34 can drive the second strong adhesive 35 and the lens 2 to be removed from the camera housing 1.

[0028] Furthermore, the thickness of the first strong adhesive layer is 0.08-0.12 mm.

[0029] In some preferred embodiments of the present invention, the thickness of the first strong adhesive layer is 0.1 mm.

[0030] Furthermore, the thickness of the foam 32 is 0.5-1 mm.

[0037] Furthermore, a lens hole 11 is formed on the camera housing 1 , and a through hole 36 is formed on the foam member 3 corresponding to the lens hole 11 .

[0038] It can be seen from the above description that the foam piece 3 can be bonded to the lens 2 and the camera housing 1 without cutting, and the installation operation is simpler.

[0039] Furthermore, a glue groove 12 is formed on the camera housing 1 and is arranged around the lens hole 11 , and the foam member 3 is arranged in the glue groove 12 .

[0040] It can be seen from the above description that the foam member 3 is arranged in the glue groove 12, which can improve the flatness of the outer surface of the camera.
