Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a lens waterproof structure. Background Art

[0002] In recent years, with the development of electronic technology, optical lenses have been widely used in various industries. In some fields, the lens needs to work in harsh outdoor environments, such as the automotive field, but the existing automotive lens equipment often has only a simple shell. The circuit board and the lens are placed in the shell, and a cover plate is provided at the opening of the shell. The lens is then extended directly out of the cover plate, which will cause a gap between the lens and the cover plate. However, when the vehicle encounters rainy and foggy weather while driving, the lens equipment using this structure will cause rain and fog to directly enter the shell from the connection between the lens and the shell, which can easily cause water to enter the lens equipment, and finally make the lens as a whole unusable. Therefore, it is necessary to provide a lens mounting structure with good waterproof properties. Utility Model Content

DETAILED DESCRIPTION

[0018] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] As attached Figure 1 ,2 As shown in Figures 3, 4, 5 and 6, the utility model provides a lens waterproof structure, including a shell 1, a cover plate 2 and a lens module 3. An opening 4 is provided on one side of the shell 1, and the lens module 3 is provided inside the shell 1. The output end of the lens module 3 faces the opening 4, and the cover plate 2 is provided at the opening 4. A protrusion module 5 is provided on the side of the cover plate 2 away from the shell 1, and the interior of the protrusion module 5 is arranged to be hollow. The output end of the lens module 3 is arranged inside the protrusion module 5. At the same time, a baffle 6 is provided at the outlet end of the protrusion module 5. The baffle 6, the protrusion module 5 and the cover plate 2 are integrally formed, so as to ensure the overall sealing when the baffle 6, the protrusion module 5 and the cover plate 2 are combined.

[0020] Therefore, when the lens module 3 is installed, the lens module 3 can be directly placed inside the housing 1, avoiding the problem of a gap between the lens and the cover plate, thereby preventing the lens module from being flooded in rainy and foggy weather, thereby ensuring the waterproofness of the overall structure;

[0021] When the lens module 3 is installed, the output end of the lens module 3 can be set to the protrusion module 5, so that the output end of the lens module 3 can be extended out of the cover plate 2 through the protrusion module. There is no need to adjust the lens module 3, and the normal use of the lens module 3 can be guaranteed.

[0022] Preferably, the baffle 6, the protruding module 5 and the cover plate 2 are made of transparent plastic material. The use of transparent plastic material can ensure that the lens module 3 can transmit light through the baffle 6 at the outlet end of the protruding module 5, thereby ensuring the normal operation of the lens module 3.
