Abstract

The invention discloses an automatic inflation / exhaust type vehicle door sealing device, and aims to provide a vehicle door sealing device having the characteristics of good sealing performance and no generation of permanent deformation of a sealing strip and capable of effectively solving the rainwater leakage problem caused by excessive gap between a vehicle door and a vehicle body door frame. The automatic inflation / exhaust type vehicle door sealing device comprises an annular inflation sealing ring encircled on the outer surface of the vehicle body door frame, and a voltage stabilizing air storage tank and an air pump arranged on a vehicle body, wherein an annular inflation inner cavity is formed in the annular inflation sealing ring; and a self-adaptive inflation execution mechanism is additionally arranged on the annular inflation sealing ring.

Description

technical field [0001] The invention relates to a car door sealing device, in particular to an automatic inflation and exhaust type car door sealing device. Background technique [0002] The door sealing device is one of the important parts of the car. The door sealing device usually includes a circle of outer door sealing strip installed on the inner surface of the car door and a circle of inner door sealing strip installed on the outer surface of the door frame of the vehicle body; when the door is closed, the inner and outer door sealing strips are squeezed, thereby A seal is formed between the door and the body door frame. [0003] At present, the sealing strip of the car door sealing device is often impacted and squeezed by the door, and the sealing strip is prone to permanent deformation during long-term use, resulting in a reduced partial sealing effect of the sealing strip, resulting in the problem of rainwater leakage. On the other hand, due to the influence of th...
