Rapid installation and rapid exchange system of electric automobile battery and rapid installation and rapid exchange method thereof

Abstract

The invention discloses a rapid installation and rapid exchange system of an electric automobile battery and a rapid installation and rapid exchange method thereof. The rapid installation and rapid exchange system comprises a battery pack, an installation plate and a battery pack protection frame arranged on an automobile body, wherein four corners of the installation plate are provided with a hoisting ring respectively, four corners of the protection frame are provided with a lock body respectively, and the lock body comprises a latch hook, a latch hook drive motor and a sensor. When the battery pack is arranged on the installation plate and hoisted to the lower part of the automobile body together with the installation plate, the hoisting ring on the installation plate hoisted up contacts the root part of the latch hook to cause the latch hook to rotate around a fixed shaft thereof and penetrate through the hoisting ring to be connected and locked with the battery pack, therefore the battery pack is fixed under the floor of the automobile body. The proposal provided by the invention is practical, reliable, simple, convenient and easy to operate, thus being capable of not only guaranteeing the rapid exchange and rapid installation of the battery pack but also meeting the arrangement requirements of most automobiles.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a battery quick-changing and quick-installing system and a quick-installing and quick-changing method for the electric vehicle. Background technique [0002] As a representative of new energy vehicles, electric vehicles have the advantages of economy and cleanliness. However, due to the limitation of battery energy, the driving range is low, which limits the promotion of electric vehicles. In order to extend the driving range of electric vehicles, the method of replacing batteries can be adopted. When the battery power is low, you can go to the charging station to quickly replace a fully charged battery pack. The battery replacement time is controlled within 3 minutes, which is similar to the fuel vehicle refueling time, which not only prolongs the driving range, but also saves time. [0003] In addition, the battery packs of electric vehicles are large in number, large in size ...

AI Technical Summary

Problems solved by technology

The first defect of this solution is that there is usually not such a large space on the car so that the battery pack can slide flexibly. The battery pack on the electric vehicle is large in size. To realize the rolling installation of the rollers, there must be no less than twice the length of the battery pack on the floor. Flat floor space; the second defect of this solution is that the battery pack can only be installed above the car floor, and the battery installation space is limited due to the impact of seats, spare tires, etc.; the third defect of this solution is that there are rollers under the battery pack, and the upper There are pressure bars, which significantly increase the height of the battery pack, resulting in a reduced ground clearance of the car and tight interior layout

Therefore, this scheme can only be applied to certain special vehicle models, and cannot be popularized in large quantities, especially it is difficult to realize on cars.
