Abstract

The invention discloses a rear air window for removing negative pressure of an automobile cab. The rear air window is mounted at a rear part of an automobile cab, the rear air window is a box body with a frame, an upper part of the box body is open, a plurality of windows are formed at a lower portion of the box bottom, each window is provided with a plugging rubber sheet, one side of each plugging rubber sheet is of a movable structure, the other side of each plugging rubber sheet is fixed or compacted on an inner side edge of the corresponding window through a partition plate, the partitionplates are vertically arranged relative to the plugging rubber sheets, and a plurality of air outlet bins are formed among the partition plates. The rear air window is advantaged in that drivers and passengers can conveniently close vehicle doors, a negative pressure problem is solved, a sealing problem of a cab is further solved, and the structure is simple, economical and practical.

Description

technical field [0001] The invention relates to components of an automobile cab, in particular to a rear windshield for removing negative pressure in an automobile cab. Background technique [0002] The car cab is the space for the driver and passengers to drive the car and ride. The airtightness and air permeability of the space are the key factors. The airtight space environment ensures comfort and cleanliness, but the air in the fully enclosed space or the air in the cab is relatively poor. When the driver closes the door, it will cause negative air pressure and prevent the door from closing or not closing tightly; or closing the door requires a lot of effort, especially when standing on the ground to close a higher door. [0003] Or setting vent holes in the cab can solve the problem of negative pressure, but it cannot achieve the airtight effect, especially the air, dust, rain, and temperature outside the cab will cause a certain temperature difference in the cab and ot...
