Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0023] Example. A positioning method for electric vehicle power battery and vehicle body, such as figure 1 with figure 2 As shown, the method forms a point positioning mechanism 1 by cooperating the point positioning pin 3 on the power battery 7 with the joint bearing 4 on the car body 8; the line positioning pin 5 on the power battery 7 and the The limit channel steel 6 on the car body 8 cooperates to form a line positioning mechanism 2; the above two different positioning mechanisms simultaneously position the power battery 7 to solve the influence of the uncertain attitude of the car body 8 on the automatic replacement of the power battery. The point positioning mechanism 1 and the line positioning mechanism 2 are arranged diagonally to the power battery 7 to ensure accurate posit...

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 invention relates to a positioning method and device for a power battery and a vehicle body of an electric vehicle, and belongs to the technical field of power battery replacement of electric vehicles. Background technique [0002] Electric vehicles use power batteries as the active power, so just like fuel vehicles need to be refueled frequently, electric vehicles need to replace power batteries frequently. When replacing the power battery of an electric vehicle, it is necessary to accurately locate the power battery and the position where the power battery is placed on the electric vehicle. However, with the change of factors such as tire inflation, uneven ground, and different models, the posture of the electric vehicle body will also change, which brings trouble to the automatic replacement of the power battery. At present, in the prior art, manual methods are often used to replace the power battery of the electric vehicle. This not only has ...
