In order to achieve the purpose, the invention adopts the following technical scheme:

the invention discloses a bus window structure convenient for escape, which comprises a window and a window groove, wherein a safety air cushion which can be broken when high pressure is applied is arranged between the inner side surface of the window and the window groove; after the bus just fell into water, the automobile body inside can not be full of by water at once, and there is great water pressure this moment the automobile body outside, and after the door window received water pressure, and the frictional force increase between the door window groove, the door window is hardly opened to the people in the automobile body, safety air cushion can be broken by the crowd after receiving water pressure, leads to the clearance between door window and the door window groove to increase, makes the door window open more easily.

Preferably, the window groove is provided with a ball which can be contacted with a window after the safety air cushion is crushed; when the safety airbag is squeezed under the action of water pressure, the car window is pressed onto the ball, and the friction force borne by the car window is changed from sliding friction to rolling friction when the car window is opened, so that the car window is opened more easily.

Preferably, the lower side of the vehicle window is provided with an inner cavity for accommodating the opened vehicle window; the distance of general bus door to chassis is bigger for the distance of bus window to roof portion, more is fit for being used for setting up the inner chamber, if set up the inner chamber in the left and right sides of door window, then when the door window is opened, the space of fleing of left and right sides is occupied, consequently, is located the inner chamber of door window downside and can increases the space that the passenger fled by furthest.

Preferably, a pressure receiving surface which is inclined upwards towards the normal direction outside the vehicle is arranged on the outer side surface of the vehicle window; when the bus falls into water, the bus can be pressed by the pressure vertical to the window surface, and the window can be subjected to a downward component force due to the fact that the pressure is obliquely downward and the outward normal direction of the pressed surface is obliquely upward, so that the window can be automatically opened when the window is subjected to water pressure, and the escape time of passengers in the bus is saved.

Preferably, the bottom of the inner cavity is provided with a connecting channel communicated with the outer side of the vehicle body; in the normal running process of the bus, if rain occurs, rainwater possibly enters the inner cavity, so that the windows of the bus can bring the rainwater into the bus in the opening and closing process to destroy the cleanness in the bus, the connecting channel can discharge the rainwater entering the inner cavity to the outside of the bus body, and the process that the rainwater enters the inner cavity and is discharged from the connecting channel can take away dust in the inner cavity to prevent dust accumulation so as to influence the normal opening and closing of the windows of the bus; in addition, when the car window is normally opened and closed, the connecting channel can prevent the inner cavity and the outside from forming air pressure difference, so that the car window is unsmooth to be opened and closed.

Preferably, a rubber pad is arranged between the outer side surface of the vehicle window and the vehicle window groove; the friction coefficient between the rubber pad and the vehicle window is large, when the vehicle window is opened and closed, the vehicle window can be stopped at any height, the stepless switch of the vehicle window is realized, when the bus falls into water, the safety air cushion is broken by the vehicle window, the gap between the vehicle window and the vehicle window groove is increased, the air cushion cannot be obstructed by the rubber pad, and the rubber pad also has the effect of preventing rainwater and dust from entering the interior of the bus body.

Preferably, the vehicle window is provided with a handle which is convenient for opening and closing the vehicle window, so that the vehicle window is more convenient and labor-saving to open and close.

Therefore, the invention has the following beneficial effects: (1) when the bus falls into water, the windows of the bus can be opened quickly and laborsavingly, so that the escape time of passengers in the bus body is shortened; (2) the vehicle window can realize stepless opening and closing, and the opening and closing are smooth.
