Description

Emergency power supply circuit for vehicle and car Technical Field The utility model relates to the technical field of car safety, in particular to an emergency power supply circuit for a car and a car. Background With the development of society and the continuous improvement of living standard, cars are gradually popularized in daily life as an important riding-replacing tool, and car driving safety is also increasingly emphasized. Accidents, such as collision, water falling, fire and the like, inevitably occur in the running process of the car, and escape speed and self-rescue capability of passengers in the accident vehicle are one of key factors for determining the survival probability of the accident. The battery of most of the existing family cars is arranged in a front cabin of a car body and is connected with low-voltage electric appliances at all positions in the car through wires, and when an engine runs, the battery stores kinetic energy of the engine as electric energy and supplies power for the low-voltage electric appliances of the whole car. When an accident occurs in the running process of the car, the battery and the positions of the wires can be damaged due to the action of external force, temperature change and the like, so that the power supply of the car is forced to be interrupted, and the car door lock, the glass lifter, the skylight, the trunk lock and other piezoelectric devices cannot work due to power failure, so that passengers are seriously hindered from escaping from the inside, and a large potential safety hazard exists. Accordingly, the prior art is still in need of improvement and development. Disclosure of utility model In view of the shortcomings of the prior art, the utility model aims to provide an emergency power supply circuit for a vehicle and a car, so as to solve the technical problem that in the prior art, when power supply of a battery is interrupted in an accident vehicle, a switch of an emergency channel such as a door lock, a glass lifter, a skylight, a trunk lock and the like cannot be opened, and passengers are prevented from escaping quickly.
