Novel liquid storage and filling cover belt oil-blocking ventilation mechanism assembly for automobile

Abstract

The invention discloses a novel liquid storage and filling cover belt oil-blocking ventilation mechanism assembly for an automobile, which comprises a liquid storage filling cover, an oil inlet rubbersealing ring, a vent rubber sealing ring, a sealing bracket, a floating block, the sealing bracket and the floating block are both arranged in the liquid storage filling cover; the floating block issleeved with the bottom of the sealing bracket and is connected with the vent rubber sealing ring; the end surface of the bottom of the sealing bracket is connected to the end surface of an oil inletof a liquid storage tank through the oil inlet rubber sealing ring; the liquid storage filling cover is arranged at the oil inlet of the liquid storage tank, the sealing bracket is provided with an air communication channel which is communicated with the outside atmosphere and the inner side of the oil inlet of the liquid storage tank, and the upper movement of the floating block under the impactof oil liquid drives the vent rubber sealing ring to seal at the air communication channel. The assembly can effectively avoid the problem that the liquid in the liquid storage tank leaks from the oilinlet of the liquid storage tank when the automobile is bumped and braked in an emergency, and has the advantages of unique design and reliable and stable performance.

Description

technical field [0001] The invention relates to a cover assembly of a liquid storage tank, in particular to a novel liquid storage filling cover assembly with an oil-blocking ventilation mechanism for automobiles. Background technique [0002] In the traditional automobile brake fluid storage cap assembly, the internal ventilation and oil resistance structure is often just a small gap cut in the center of the thin rubber sealing ring, or a swivel channel is designed inside the sealing bracket to achieve the ventilation and oil resistance effect, but These two traditional oil-blocking and ventilating structures can only resist the liquid splash caused by the bumping of the car. It is difficult to resist the rapid impact of the liquid in the liquid storage tank on the liquid storage tank cover when the car is in emergency braking, and there will often be brake fluid Leaking from the liquid storage cap, dripping into the front engine compartment of the car, and even the leaked ...
