Movable sealing device for large-opening rear cabin door of armored vehicle

Abstract

The invention discloses a movable sealing device for a large-opening rear cabin door of an armored vehicle, belongs to the technical field of armored vehicles and solves the problems that vehicle vibration causes distorting deformation of a vehicle body due to increased size of an opening for the cabin door of an armored vehicle, and that common seal strips have poor sealing effect. The movable sealing device comprises an inflating component, a sealing component and a control component. During closing of a door, the inflating component performs inflating, a raised channel of an inflatable rubber strip inflated comes in tight contact with a sealing side door plate, and the door plate and a door frame are strictly sealed; during opening of the door, the inflatable rubber strip is relieved, an extensible portion of the inflatable rubber strip is retracted into a channel of the door frame and leaves the sealing side door plate. When the sealing side door plate has distorting deformation, tight fitting is achieved through flexible mobile sealing of the inflatable sealing rubber strip; zero leakage is ensured for the vehicle during float-crossing on water, particularly for the fact thata thin-shelled armored vehicle may vibrate and experience distorting deformation during travelling under complex road conditions.

Description

technical field [0001] The invention belongs to the technical field of armored vehicles, and in particular relates to a mobile sealing device for a large-opening rear hatch of an armored vehicle that can be used as a springboard. Background technique [0002] At present, the western-style humanized design of large-opening rear hatches in armored vehicles, due to the relatively large opening, is affected by processing and assembly precision or is subject to thermal expansion and contraction due to changes in ambient temperature, resulting in inconsistent gaps or gaps that need to be sealed. The variation range is generally 3-5 mm or even larger. At the same time, the body of a thin-shell armored vehicle will vibrate during driving under complex road conditions, which will cause distortion and deformation, which will cause difficulty in closing the rear hatch and poor sealing. And other problems, it is difficult to achieve the ideal sealing effect with ordinary sealing strips....

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of poor sealing performance of ordinary sealing rubber strips in the design of the rear hatch with large openings and the thin-shell armored vehicle body due to vibration and distortion of the vehicle body, a mobile sealing device that can be used independently on armored vehicles is provided

It solves the problem that the sealing effect of ordinary sealing rubber strips is not ideal due to the large opening size of the rear hatch of the armored vehicle and the distortion of the vehicle body caused by vehicle vibration.
