An electric vehicle with side-to-side battery replacement at the bottom of the vehicle and a battery replacement device thereof

Abstract

An electric vehicle with side-to-side linkage battery replacement at the bottom of the vehicle and a battery replacement device thereof. The chassis of the invention is mechanically connected with a battery box (1); the battery box (1) is a rectangular body, and the battery box (1) The open ends at both ends are arranged on the two sides of the abdomen of the chassis, and a cover plate (5) capable of opening and closing is provided at the open ends. The beneficial effects of the present invention are: 1. The cost is low; 2. The battery replacement speed is very fast: compared with the second battery replacement solution in the background technology, the present invention can be carried out simultaneously when removing the battery and installing the battery. 3. Accurate positioning and convenient replacement: due to the combination of positioning pins, positioning holes, positioning rails, and positioning slots, it can ensure accurate positioning when replacing batteries. sex. 4. The present invention can simultaneously replace batteries for multiple electric vehicles at the same time and on the same site.

Description

technical field [0001] The invention belongs to the technical field of battery changing system structure, in particular to the technical field of electric vehicle battery changing system structure. Background technique [0002] There are generally two ways to replace batteries in existing electric vehicles: 1. The batteries are respectively arranged at the head and the tail. 2. Install the battery as a whole on the chassis of the car. These two battery setting methods all have certain advantages and disadvantages: for example, the advantage of the first method is that it can ensure the weight balance between the front and rear of the vehicle, and the vehicle will not run badly because the front is heavy and the rear is light or the rear is heavy and the front is light. But the disadvantage of this method is that when the battery is connected, the internal connection of the vehicle is complicated, and a lot of wires will be generated, the wires are prone to failure, and even...

AI Technical Summary

Problems solved by technology

The disadvantages of this process are that the replacement is very time-consuming and difficult to locate

In addition, the manufacturing cost of special equipment for battery replacement is very high. There is a similar car battery replacement positioning system in Germany, which costs up to 3 million U.S. dollars; and the battery is not tightly sealed after replacement, and it is easy to enter water and dust

[0003] In addition, the above two battery replacement systems are not yet popular in China. Currently, charging piles are the mainstays. After purchasing electric vehicles, citizens generally use them during the day and park them in residential areas at night for charging, and the charging time is as long as 8 hours. -10 hours

This greatly reduces the utilization efficiency of electric vehicles and seriously affects the development of electric vehicles.
