Problems solved by technology
Using the plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; 2. The charging time is too long, at least 2 to 4 hours, which is comparable to that of ordinary cars. Compared with electric vehicles, it takes too long to replenish energy, which is very inconvenient and far from meeting people's needs.
However, for small electric vehicles, due to the low chassis, the battery replacement space formed after the battery frame is lowered to the ground is relatively small, resulting in inconvenient operation and low battery replacement efficiency.

The invention relates to a battery frame lifting device facilitating battery replacing of an electric vehicle. The battery frame lifting device comprises a motor, a scissor jack and a ball pin mechanism. A motor supporting seat is mounted on a rocking seat of the scissor jack, a motor is vertically mounted on the motor supporting seat, and a rotating shaft of the motor is vertically downward and is connected with a lead screw of the scissor jack through a transmission mechanism; the ball pin mechanism is mounted on a saddle of the scissor jack; and a base of the scissor jack is connected witha battery frame mounted at the bottom of the electric vehicle, the top of the ball pin mechanism is connected with an electric vehicle body, and the driving end of the motor is connected with an electric vehicle control system. According to the battery frame lifting device facilitating battery replacing of the electric vehicle, rising and falling of the battery frame mounted at an electric vehiclechassis can be controlled, after the battery frame reaches the ground, the electric vehicle can further be lifted to leave the ground, thus the battery replacing space is expanded effectively, it isguaranteed that battery replacing operation is convenient, and the battery replacing efficiency is improved.
Description
technical field [0001] The invention relates to an auxiliary device for battery replacement of an electric vehicle, in particular to a battery frame lifting device for improving the battery replacement space of the electric vehicle and facilitating the battery replacement of the electric vehicle. Background technique [0002] In order to achieve the purpose of energy saving and emission reduction, electric vehicles powered by power batteries are becoming more and more popular. At present, the power supply methods of electric vehicle power batteries are generally divided into two methods: plug-in charging with the car and battery replacement. Among them, there are two modes of plug-in charging: slow charging and fast charging. The plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; 2. The charging time is too long, at least 2 to 4 hours,...
