The invention relates to mounting and replacement of batteries of electric vehicle, in particular to a battery box locking device. The device aims to solve the problems that a battery box cannot be reliably mounted and rapidly replaced and cannot prevent looseness during driving. In order to solve the problems, the device comprises a mounting casing, a fastening piece, a flange, a compressing piece and an anti-loose component, wherein the flange cannot rotate around the axial direction of the fastening piece but can slide in the axial direction; the compressing piece can compress the flange to enable the flange to be compressed to and in contact with the mounting flange and to ensure that the flange and the fastening piece cannot rotate relative to the mounting casing; the fastening piece can connect the mounting casing to the body of the electric vehicle. As the structure is adopted, the locking device can safely and reliably mount and rapidly and conveniently replace the battery box and realize the rigid fixing of the battery box, thereby being capable of preventing looseness of the battery box during driving.
Description
technical field [0001] The invention relates to battery installation and replacement of an electric vehicle, and specifically provides a battery box locking device and a battery box including the battery box locking device. Background technique [0002] my country is a country that is relatively short of oil resources, and needs to import a large amount of crude oil and refined oil every year. With the rapid increase of car ownership, domestic fuel supply pressure is extremely high. The large-scale promotion of electric vehicles is not only related to national oil security and energy security, but also can reduce the dependence of automobiles on imported oil. Therefore, the development of electric vehicles is an important strategic choice to ensure the sustainable development of the automobile industry. [0003] Battery replacement for electric vehicles is a useful supplement to battery charging. Replacing the battery can realize the rapid replenishment of vehicle energy,...
