    [0001] The invention relates to the field of automobiles, and in particular to a mounting structure for a battery pack, a battery pack, and an automobile with such a mounting structure for a battery pack. Background Art
    [0002] Recently, batteries have been largely commercialized as an alternative vehicle power source. However, there are still many problems to be overcome when the batteries are used on a large scale. Perhaps the biggest challenge is charging. ICE vehicles are easily refuelled in gas stations in minutes. Electric vehicles require specialized charging equipment and a large amount of charging time (in hours). Electric automobiles charge more frequently than fuel automobiles, and a smaller range than an ICE vehicle makes the problem worse. It is not hard to park an electric automobile for a few hours or overnight in the company or at home, but parking a vehicle for hours during a long-distance trip is not practical.
    [0003] Swappable battery packs are a promising technology for electric automobiles, which replaces the traditional long battery charge cycle and automatically and easily swaps a used battery on a vehicle for a fresh battery pack in a battery swap station, and the process lasts for a very short time.
    [0004] Hitherto, there have been many methods for vehicles to retain and fix a battery pack, most of which use a bolt assembly to retain the battery pack, which requires an external drive mechanism and is time-consuming. In addition, a large number of sensors and electronics required for battery swap operations in battery swap stations make the operation unreliable and result in poor robustness. Summary of the Invention
    [0005] The invention proposes a mounting structure for a battery pack, which can quickly swap a battery pack.
    [0006] The mounting structure for a battery pack proposed according to one aspect of the invention comprises a plug disposed on a battery pack, the plug being horizontally movable with respect to the battery pack, the bottom of the plug being provided with a bevel configured to cooperate with a mating bevel provided on a vehicle, thereby mounting the battery pack on the vehicle.
    [0007] According to one aspect of the invention, a battery pack is further proposed, wherein a plug is disposed on the battery pack, the plug is horizontally movable with respect to the battery pack, and the bottom of the plug is provided with a bevel configured to cooperate with a mating bevel provided on a vehicle. With the battery pack configured in such a manner, a quick battery pack swap can be realized.
    [0008] In addition, another aspect of the invention provides an automobile with such a mounting structure for a battery pack. Since the automobile has the mounting structure for a battery pack according to the invention, it is possible for the automobile to have the advantages as described above.
    [0009] The beneficial effects of the invention comprise: the battery pack is mounted on the vehicle by means of cooperation between the bevel on the bottom of the plug and the mating bevel on the vehicle, and the battery pack is conveniently loaded or unloaded by the horizontal movement of the plug relative to the battery pack, thus facilitating rapid swapping of a used battery pack for a fresh battery pack. Brief Description of the Drawings
    [0010] The disclosure of the invention is now described with reference to accompanying drawings. It should be appreciated that the accompanying drawings are merely used for the purpose of illustration, and are not intended to limit the scope of protection of the invention.
