This scheme is based on battery package 6000 can dismantle the bottom of connecting in electric automobile through locking means, and locking means is including the locking mechanism who has L type locked groove and fix the locking axle on battery package 6000 side, and the locking axle further horizontal migration to battery package 6000 locking after the L type locked groove vertical migration targets in place succeeds, and battery package 6000 realizes the locking by further horizontal migration after the vertical migration promptly. And when the battery pack 6000 rises to the proper position, the liquid cooling connecting device of the battery pack 6000 is in sealed communication with the liquid cooling connecting device of the electric automobile. Therefore, when the battery pack 6000 moves horizontally, the liquid cooling connecting device of the battery pack 6000 and the liquid cooling connecting device of the electric automobile are kept in a fixed position through the moving part, namely, the connecting valve of the battery pack 6000 moves in the opposite direction relative to the moving part, and the accuracy, the sealing performance and the connectivity of liquid cooling connection are guaranteed.
In another embodiment, the battery pack 6000 has all the features of the above embodiments, and further includes: the quick-change battery end liquid cooling connecting device is two in number, wherein one of the quick-change battery end liquid cooling connecting device is used as an input part of cooling liquid, and the other quick-change battery end liquid cooling connecting device is used as an output part of the cooling liquid. The arrangement mode of the liquid cooling pipeline in the battery pack 6000 is more flexible by separately arranging the input part and the output part of the liquid cooling connecting device. Preferably, the two quick-change battery end liquid-cooling connecting devices are respectively arranged at two opposite ends of the battery pack 6000. The input part and the output part of the liquid cooling connecting device are arranged at the two ends of the battery pack 6000, so that the layout of liquid cooling pipelines in the battery pack 6000 can be optimized, the occupied space of the liquid cooling pipelines is reduced, and the heat exchange efficiency is improved.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
