Detailed Description

In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 to 3, in an embodiment, the vehicle includes a body 10, a door 20, a door lock, a whole vehicle power supply, a door lock switching circuit 30, and a door lock control circuit 40. The vehicle may be an electric vehicle, a hybrid vehicle, a fuel vehicle, or the like.

The door 20 is mounted on the vehicle body 10, and a door lock is used for locking and unlocking the door 20, the door 20 cannot be opened when the vehicle body 10 and the door 20 are locked, and the door 20 can move relative to the vehicle body 10 when the door 20 is unlocked to enable the door 20 to be opened or closed.

The whole car power supply can supply power to the door lock switch circuit 30, and the door lock switch circuit 30 is used for controlling locking or unlocking of a door lock. The door lock can lock the door 20 when locked, and unlock the door 20 when unlocked. The whole vehicle power supply is a battery or the like provided in the vehicle itself for supplying power to a corresponding electric device of the vehicle. For example, when the vehicle is a hybrid vehicle or an electric vehicle, the whole vehicle power supply includes a power battery of the vehicle and a corresponding backup battery. The door lock switch circuit 30 may be of a conventional type, and the present embodiment is not limited thereto.

The door lock control circuit 40 is an emergency circuit, when the electric quantity of the whole vehicle power supply is exhausted, the whole vehicle power supply cannot supply power to the door lock switch circuit 30, and at this time, the door lock control circuit 40 can supply power to the door lock switch circuit 30 by adopting the standby power supply 50 so as to lock or unlock the door lock. The standby power supply 50 may be a mobile power supply such as a charger, or may be a power supply such as a commercial power. It should be appreciated that the power output of the door lock control circuit 40 is electrically connected to the door lock circuit 30, and the power input of the door lock control circuit 40 is electrically connected to the standby power supply 50, so that the standby power supply 50 can supply power to the door lock switch circuit 30 through the door lock control circuit 40.

In addition, the door lock is controlled mainly by controlling the forward and reverse rotation of the motor of the door lock, which can be regarded as a part of the door lock switching circuit 30, so as to lock or unlock the door lock. For example, when the motor is controlled to rotate forward, locking of the door lock can be achieved, and when the motor is controlled to rotate backward, unlocking of the door lock can be achieved. When the whole car power supply is exhausted and the car door 20 needs to be opened, the motor can be powered forward through the standby power supply 50 so as to rotate forward, and when the whole car power supply is exhausted and the car door 20 needs to be locked, the motor can be powered backward through the standby power supply 50 so as to rotate backward.

In addition, the door lock switching circuit 30 includes a power connection terminal, and the power connection terminal of the door lock switching circuit 30 may be electrically connected to a whole vehicle power supply so as to supply power to the door lock switching circuit 30 through the whole vehicle power supply. The power output terminal of the door lock control circuit 40 may be electrically connected to the power connection terminal of the door lock switch circuit 30, so that the standby power 50 may supply power to the entire door lock switch circuit 30. Of course, when the standby power supply 50 supplies power to the door lock switch circuit 30, only a part of the circuits of the door lock switch circuit 30 may be supplied power, for example, the power output end of the door lock control circuit 40 may be directly and electrically connected to the power connection end of the motor of the door lock, and at this time, the standby power supply 50 may only supply power to the motor of the door lock.

That is, by the arrangement of the present embodiment, when the whole vehicle is powered off due to the exhaustion of the battery, the standby power supply 50 is used to supply power to the door lock, so that the vehicle door 20 can be opened conveniently. It should be understood that the power output of the door lock control circuit 40 is the second terminal 13, and the power input of the door lock control circuit 40 is the first terminal 12.

When the whole vehicle power supply is powered on, the control module 11 can be continuously powered on, so that the first terminal 12 and the second terminal 13 can be kept disconnected, and at the moment, even if the first terminal 12 is electrically connected with the standby power supply 50, the standby power supply 50 can not power the door lock.
