Automatic window opening and unlocking device for vehicles falling into water and rolling over

Abstract

The invention provides an automatic window opening and unlocking device for vehicles falling into water and rolling over. The automatic window opening and unlocking device comprises a first detection assembly and a second detection assembly, when the vehicles incline and fall into water, due to the fact that a first limiting cylinder is kept vertically downward, the inner wall of the first limiting cylinder cannot block a buoyancy piece, and the floating speed of the buoyancy piece is high. A first change-over switch can be quickly driven to act, and therefore the time for opening a vehicle window and unlocking a vehicle door is shortened, and personnel escape is facilitated. In addition, when the vehicles fall into water vertically, due to the fact that the first limiting cylinder is still arranged vertically downwards, the buoyancy piece can still float upwards, and compared with the prior art that the buoyancy piece does not act, the application range is widened, and reliability is improved. In conclusion, when the vehicles roll over or overturn on the road surface, the second detection assembly can conduct control to achieve automatic window opening and unlocking. When the vehicles roll over and fall into water, the first detection assembly can conduct control to achieve automatic window opening and unlocking, and therefore automatic window opening and unlocking can be achieved when the vehicles encounter various conditions, and personal safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automatic window opening and unlocking device for vehicles falling into water and rolling over. Background technique [0002] When an existing vehicle falls into water, it is difficult to open the door due to the high external water pressure, and it is difficult to avoid being injured by broken glass by smashing the window glass to escape. [0003] In order to solve the above problems, Chinese patent document CN105150977A discloses an integrated switch for detecting falling into the water and tilting state and a drowning self-rescue system using the switch. The component and the action switch are provided with a plurality of water inlet holes on the side wall of the limit cylinder. When the vehicle rolls over and falls into the water, the water will enter the limit cylinder, and the floating ball assembly will move upward under the buoyancy of the water, thereby dri...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of slow response speed of the drowning self-rescue system in the prior art, which is unfavorable for personnel to escape, so as to provide a fast response speed, high safety and reliability automatic opening and closing system for vehicles falling into water and rollover.
