Problems solved by technology

Although such a design solves the waterproof of the whole equipment well, it cannot meet the high and low temperature resistance requirements of the equipment.
[0008] 2. Pure high and low temperature resistance design, leaving ordinary straight air holes, it is difficult to meet the waterproof requirements of the entire equipment in the IP65 and above tests
[0011] (1) If there is no space for the circuit board or filler inside the shell to design the ribs, this method is not feasible, so this method has certain limitations;
[0012] (2) Due to the expansion of gas inside the equipment at high temperature, the reinforcing ribs pull the shell to prevent the expansion of the shell and bear the force caused by the gas expansion, resulting in obvious white marks at the position of the reinforcing ribs from the outside, which affects the appearance of the equipment
[0016] In order to adapt to the high temperature environment of the product, the usual design is to design a vent hole for the product shell, and the ordinary linear vent design does solve the problem of high and low temperature, but it brings difficulties to the waterproof design of the entire product , making it difficult for the entire product to achieve a relatively high waterproof level

Abstract

The invention discloses an interior equipment casing with high environmental adaptability. The casing includes an outer casing edge and an outer casing edge, wherein the outer casing edge forms an inner chamber, the inner chamber is used for accommodating a circuit board or a filler, a casing wall between the inner casing edge and the outer casing edge is internally provided with a gas passage structure, the gas passage structure includes at least a turning point, gas heated and expanded in the inner chamber can be partially exhausted through the gas passage structure, and the water can be further stopped from flowing into the inner chamber. The casing is advantaged in that through setting the gas passage structure, a problem of deformation caused by gas expansion due to heat in the equipment casing in a vehicle can be avoided, and the waterproof function can be further achieved.

Description

technical field [0001] The invention relates to the field of casings of automotive electronic products, in particular to a high environmental adaptability casing for in-vehicle equipment. Background technique [0002] At present, the requirements for anti-deformation, anti-expansion, and waterproof of the casing of electronic products or electronic equipment are getting higher and higher. The electronic equipment in the vehicle is often damaged or deformed due to vehicle collisions, temperature changes, etc., and sometimes the equipment is flooded due to vehicle wading or rain. Deformation or water ingress caused by these factors is often due to design defects. Once the equipment encounters water, it will cause equipment failure, failure or even permanent damage. [0003] The reliability design of the casing of automotive electronic equipment is to consider the waterproof design, and the second is the temperature resistance design. Waterproof refers to preventing water or w...
