Waterproof case for in-vehicle camera

Abstract

A waterproof case for an in-vehicle camera includes a front case part and a rear case part, and houses imaging means such as the imaging device therein. A packing member is set between the front case part and the rear case part, and waterproofs and seals the space therebetween. A water-stop wall part is protrudingly formed on a flange part which is an attaching portion of the rear case part at a peripheral of the packing member. A concave part, into which the water-stop wall part can be fitted, is formed on an opening peripheral part which is an attaching portion of the front case part.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a technique for waterproofing an in-vehicle camera provided outside a vehicle. [0003] 2. Description of the Related Art [0004] There is a technique to take an image of periphery of a vehicle, particularly a dead zone, with an in-vehicle camera provided outside the vehicle and to display the image on a display apparatus inside the vehicle. [0005] Since such in-vehicle camera is provided outside the vehicle body, it is required to have a sufficient waterproof property. [0006] In a general waterproof structure of such in-vehicle camera, a packing is held between a front case and a rear case, which constitutes an outer part of the in-vehicle camera, and the cases are screwed shut. [0007] However, in such waterproof structure, since a packing is compressed and disposed between the front case and the rear case, a small clearance is formed in an attaching portion between the front case and ...

AI Technical Summary

Benefits of technology

The invention is a waterproof case for an in-vehicle camera that has excellent waterproof properties. The case includes a first case part, a second case part that forms a case body with the first case part, a packing member that waterproofs and seals the space between the first case part and the second case part, and a water preventing section that prevents the packing member from being exposed to water outside. The water preventing section may include a water-stop wall part that prevents high pressure injection water from reaching the packing member during car washing. The case has a small clearance between the first case part and the second case part, and the water-stop wall part maintains a constant positional relation between the first case part and the second case part to prevent viewing scope defects. The case has a compact structure and is efficient in preventing water infiltration.

Problems solved by technology

Accordingly, when washing a vehicle with high pressure, an injection water of high pressure may directly hit the packing.

In such case, there is a problem that the packing is pressed inwardly by the water pressure, whereby a waterproof property is deteriorated.
