Positioning method and apparatus for power battery of electric car and car body

Abstract

The invention discloses a positioning method and an apparatus for a power battery of an electric car and a car body. According to the invention, a point positioning mechanism is formed through fit between a point positioning pin and a joint bearing, wherein the point positioning pin is equipped on the power battery and the joint bearing is equipped on the car body. A line positioning mechanism is fit constituted of a line positioning pin and a limit channel steel, wherein the line positioning pin is arranged on the power battery and the limit channel steel is arranged on the car body; and positioning is carried out to the power battery simultaneously by the above two different positioning mechanisms to solve influence of undetermined factors of car body posture to automatic replacement of the power battery. With the two different positioning modes of the point positioning mechanism and the line positioning mechanism, effects of some factors are overcome. The factors comprise different car types, different aeration quantity of tyres of the electric power car, unevenness of ground and the like. The effects can cause different car body postures and bring trouble to the automatic replacement of the power battery. Accurate positioning of the power battery is realized, wherein the power battery is placed at a position where the power battery should be placed on the electric car. According to the invention, a guiding angle can be automatically adjusted. The method and the apparatus have the advantages of simple structure, reliable guidance and high positioning accuracy.

Description

Technical field [0001] The present invention involves a positioning method and device for electric vehicle power batteries and vehicles, which belongs to the technology field of power battery replacement of electric vehicles. Background technique [0002] Electric vehicles use power batteries as active power, so it is like fuel vehicles need to refuel frequently. Electric vehicles need to replace power batteries frequently.When changing the power battery, electric vehicles need to accurately position the power battery with the power battery on the electric vehicle.However, the body's posture will also cause trouble with the changes in factors such as the tire inflection, the ground unevenness of the ground, and the different models of the model.At present, in existing technologies, artificially uses artificial ways to replace electric vehicles.This not only has the problem of low replacement efficiency, but also the problem of time and effort. Invention content [0003] The purp...
