Vehicle emergency door opening device and method and vehicle

Abstract

The invention relates to the technical field of vehicles, and discloses a vehicle emergency door opening device and method and a vehicle, and the vehicle emergency door opening device comprises a vehicle exterior door lock pull wire, a motor locking mechanism, an electromagnetic locking mechanism and a control device; the control device is used for controlling the motor locking mechanism to release the vehicle exterior door lock pull wire and controlling the electromagnetic locking mechanism to lock the vehicle exterior door lock pull wire when the vehicle exterior door lock pull wire meets a preset pre-release condition, so that the vehicle exterior door lock pull wire is in a pre-release state; when the outside door lock pull wire is in the pre-release state and the electromagnetic locking mechanism is not powered, the electromagnetic locking mechanism can automatically release the outside door lock pull wire so that the outside door lock pull wire can be in the release state, in this way, people outside the automobile can unlock the automobile door through the outside door lock pull wire, rescue can be carried out in time, and the safety of the automobile is improved. And meanwhile, the problem of driving risks caused by false triggering of unlocking of the vehicle door due to a collision early-warning unlocking mode in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle emergency door opening device, method and vehicle. Background technique [0002] At present, the collision unlocking method is generally adopted in the industry. Specifically, when a vehicle collides with an accident, the vehicle automatically controls the door unlocking so that rescuers outside the vehicle can open the door to rescue people inside the vehicle. However, when a vehicle collides with an accident, if the vehicle is powered off before controlling the unlocking of the door, the door cannot be successfully unlocked, which makes it difficult for rescuers outside the vehicle to rescue people in the vehicle. At present, in order to overcome the above problems, the unlocking method of collision warning is usually adopted, and the principle of unlocking of collision warning is specifically: using the collision warning signal, it is judged that the vehicle has a c...

Problems solved by technology

However, when a vehicle collides with an accident, if the vehicle is powered off before controlling the unlocking of the doors, the doors will not be able to be successfully unlocked, making it difficult for rescuers outside the vehicle to rescue people inside the vehicle.

At present, in order to overcome the above problems, the unlocking method of collision warning is usually adopted, and the principle of unlocking of collision warning is specifically: using the collision warning signal, it is judged that the vehicle has a collision risk and then unlocks the door lock. However, this method of collision warning unlocking, It is easy to accidentally trigger the unlocking of the door during driving, which may cause the risk of interfering with driving safety. For example, when the vehicle encounters a height limit pole, it may be misjudged that the whole vehicle is at risk of collision and the unlocking of the door may be triggered by mistake
