Abstract

The invention relates to the field of new energy automobile accessories, and discloses a breathable waterproof valve for a battery box of a new energy automobile. The breathable waterproof valve for the battery box of the new energy automobile comprises a positioning pipe body, a cover plate and a breathable waterproof film, elastic connecting devices are arranged between the two sides of the positioning pipe body and the two sides of the cover plate, a sliding sealing plate attached to the side face of the positioning pipe body is arranged on the elastic connecting devices, the sliding sealing plate can rotate relative to the positioning pipe body, the breathable waterproof film is arranged between the sliding sealing plate and the cover plate, and the breathable waterproof film is in a tubular shape between the sliding sealing plate and the cover plate. According to the breathable waterproof valve for the battery box of the new energy automobile, through the structural design that the breathable waterproof film is arranged between the positioning pipe body and the cover plate in a tubular shape and can rotate relative to the positioning pipe body and the cover plate, under the condition that the inner diameter of the positioning pipe body is not changed, and compared with an existing breathable waterproof valve for the battery box, the area of air flowing through the breathable waterproof film is larger, so that the breathability efficiency of the battery box of the new energy automobile is higher, and the effect is better.

Description

technical field [0001] The invention relates to the field of new energy automobile accessories, in particular to a ventilating and waterproof valve for a battery box of a new energy automobile. Background technique [0002] New energy vehicles are mainly electric-driven vehicles. Today, as energy problems and environmental pollution problems continue to intensify, the development of new energy vehicles has become an important strategy to implement the national requirements for energy conservation, emission reduction, and development of a low-carbon economy. The batteries of existing new energy vehicles The battery box is one of the essential components of the car, and the battery box is usually equipped with a breathable waterproof valve to balance the air pressure difference inside and outside the battery box, and at the same time prevent water vapor from entering the battery box. [0003] However, the breathable and waterproof membrane of the existing breathable and waterp...
