Description

Rear air window for removing negative pressure in automobile cab

Technical Field

The invention relates to a component of an automobile cab, in particular to a rear windshield for removing negative pressure in the automobile cab.

Background

The automobile cab is a space for drivers and passengers to drive and ride, the air tightness and air permeability of the space are key factors, the closed space environment ensures comfort, cleanness and sanitation, but the fully closed space or the air in the cab is relatively not circulated, and when the driver closes the automobile door, the negative pressure of the air can be caused to prevent the automobile door from being closed or not closed tightly; or the door needs to be closed with great effort, especially when standing on the ground to close a door that is tall.

Or the problem of negative pressure can be solved by arranging the vent hole in the cab, but the sealing effect cannot be achieved, and particularly, air, dust, rainwater and temperature outside the cab can cause a certain temperature difference and other series of environmental factors in the cab.

Disclosure of Invention

The invention provides a rear windshield for an automobile cab to solve the problem that negative pressure of the automobile cab causes an automobile switch and the problem of sealing of the cab, and particularly provides a rear windshield for the automobile cab to remove the negative pressure.

Therefore, the technical scheme of the invention is that the rear windshield for removing the negative pressure in the automobile cab comprises a rear windshield arranged at the rear part of the automobile cab, and is characterized in that: the back wind window be a box body that has the frame, the upper portion of box body is uncovered, the lower part of box bottom is equipped with a plurality of windows, every window is equipped with the shutoff sheet rubber respectively, one side of every shutoff sheet rubber is movable structure, the another side of every shutoff sheet rubber is fixed or the compaction is at the inside side of window through the baffle, wherein the baffle is for the vertical setting of shutoff sheet rubber, forms a plurality of gas outlets storehouse between a plurality of baffles simultaneously.

The further improvement lies in that: the multiple windows at the lower part of the box bottom are arranged in a step structure, wherein each window is further divided into multiple small windows from the outside.

The further improvement lies in that: a shutter is arranged outside the upper opening of the box body through a filter screen.

The further improvement lies in that: and a positioning pin is also arranged between the shutter and the frame of the box body.

The further improvement lies in that: the edge of the shutter and the edge of the box body are sleeved with a circle of sealing ring, wherein the sealing ring protrudes out of the shutter to form an outer frame, and the sealing ring forms a sealing surface under the edge of the box body.

The further improvement lies in that: an included angle of 45-75 degrees is formed between the side surface of the box body and the open surface of the box body.

Has the advantages that:

the rear air window is assembled behind the cab, the plugging rubber sheets plug the plurality of windows and exhaust through the plurality of air outlet bins to form a one-way ventilation channel, at the moment, when a driver closes the vehicle door, air flow formed by the vehicle door and the cab naturally exhausts through the air outlet bins, the plurality of air outlet bins are arranged to help to disperse the air flow, meanwhile, the vehicle door is prevented from impacting a door frame of the cab, and the purpose of safe use is achieved by utilizing the buffering of the air flow; meanwhile, the plugging rubber sheets plug the plurality of windows, so that air outside the cab has a blocking effect, and dust, rainwater and temperature outside the cab are blocked.

The plurality of windows at the lower part of the box bottom are arranged in a step structure, wherein each window is further divided into a plurality of small windows from the outside. The plurality of windows are arranged in a step structure and can disperse airflow, and each window is divided into a plurality of small windows from the outside so as to subdivide the airflow and achieve the aim of buffering.

The filter screen and the louver are arranged, and the filter screen and the louver also filter external air and change the direction of the external air, so that the air outlet bin is clean and sanitary, and cross contamination is prevented.

The positioning pin is arranged between the shutter and the frame of the box body so as to facilitate and fast installation of the shutter.

The shutter and the box body are connected into a whole through the arrangement of the sealing ring, meanwhile, the outer frame is attractive, the sealing surface is in surface-to-surface contact with the sealing of the cab after the rear air window is installed, and the sealing surface is increased.

An included angle of 45-75 degrees is formed between the side face of the box body and the open face of the box body, so that the box body forms an inclined angle in a cab after being installed, has certain directionality, corresponds to the opening and closing angle and radian of a vehicle door, and is used for better removing negative pressure caused by the cab as soon as possible.

The arrangement of the invention is convenient for the driver and passengers to close the vehicle door, solves the problem of negative pressure and the problem of sealing of the cab, and has simple structure, economy and applicability.
