Abstract

The invention discloses a method and system for replacing a power battery of an electric car. A car body connecting device comprises a power unit for supplying driving force, a transmission device for supplying rotating torque and changing the transmission direction, racks and locking devices. The transmission device is a transition steering gear and toothed rod mechanism. A transmission gear at one end of the transition steering gear and toothed rod mechanism is connected with the power unit. A driving gear at the other end of the transition steering gear and toothed rod mechanism is meshed with one end of each rack. The other ends of the racks are fixedly connected with the locking devices. The locking devices are inserted type special-shaped taper pin mechanisms. The power unit supplies the driving force to drive the transmission device to drive the racks to retreat and go forward relatively so that the locking devices, namely, the inserted type special-shaped taper pin mechanisms at the tail ends of the racks can be separated from and connected with a power battery box. The system ensures that the power battery installed on a car body of the electric car can be safely, conveniently and quickly replaced.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method and system for replacing a power battery of an electric vehicle. Background technique [0002] With the global energy shortage, the problem of environmental pollution is becoming more and more serious. Under the general trend of environmental protection and clean energy concepts, electric vehicles have a very broad development prospect because they have less impact on the environment than traditional vehicles. An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Among them, the power battery is the core of electric vehicles, but the insufficient endurance of power batteries has always been the bottleneck that plagues the development of electric vehicles. [0003] Now there is an operation mode that does not need to charge the po...
