Waterproof and anti-collision structure arranged in automobile circuit board

Abstract

The invention discloses a waterproof and anti-collision structure arranged in an automobile circuit board. The structure comprises an outer layer upper cover, an outer layer upper cover seal ring, aninner layer upper cover, an internal circuit board, a rubber anti-collision backing ring, an inner layer shell, an outer layer shell, a fixed convex lug, an outer layer lower cover, an outer layer lower cover seal ring and an inner layer upper cover seal ring; the automobile produces the bumping in the driving process, the bumping transmitted to the automobile circuit board is greatly reduced through the springs at the inner sides of the inner layer shell and the outer layer shell, thereby improving the anti-collision capacity of the circuit board; the rubber anti-collision backing ring in theinner layer shell further improves the anti-collision performance of the anti-collision structure; a double-deck wrapping structure is provided, a boss-groove matching structure is adopted at a connecting part, the boss is upward and the groove is downward, thereby preventing the water from entering the shell from the connecting part; seal rings are adopted at various connecting parts, the outside water stains cannot enter the inner layer shell, thereby preventing the water from entering the circuit board, and the waterproof capacity is greatly improved.

Description

technical field [0001] The invention relates to the field of automobile interior circuit boards, in particular to a waterproof and anti-collision structure installed inside the automobile circuit board. Background technique [0002] The circuit board of the car is an important part of the car. The damage of the circuit board will cause the loss of most of the functions of the car, and even threaten the life of the driver. The circuit board of the existing car is mainly installed directly inside the car body. Waterproof and anti-collision capabilities are seriously lacking, which leads to the damage of the car due to water ingress in the circuit board of the car when the existing car is in the rainy day or in the process of walking on the waterway, or when the car is walking on the potholed road, the car The circuit board of the car is damaged by collision and causes damage to the car, so the emergence of a waterproof and anti-collision structure installed inside the circuit ...
