Abstract

The invention discloses a fixing device and an automobile, and relates to the technical field of mechanical devices. The fixing device and the automobile solve the problems that in the prior art, nutscannot be replaced due to the fact that the nuts used for fixing a power battery pack is welded on an automatic frame, and fixing effect is poor after usage for a long time. The fixing device comprises a bolt, a gear nut, a locking mechanism and a base used for fixing the locking mechanism, wherein the base is fixedly arranged on the automobile frame, the base comprises a supporting part used forsupporting the gear nut and a replacement part used for disassembling the gear nut, the supporting part and the replacement part communicate with each other, the locking mechanism is used for lockingthe gear nut assembled on the supporting part, and the bolt and the locked gear nut are in threaded connection with the fixed power battery pack. The automobile comprises the fixing device provided in the technical scheme.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a fixing device and an automobile. Background technique [0002] With the development of social economy and the improvement of human awareness of energy conservation and environmental protection, electric vehicles, as new energy vehicles, are increasingly becoming the direction of future automobile development. Among them, the energy storage system of the electric vehicle, such as the battery is a key component of the electric vehicle. At present, the charging time of batteries of electric vehicles is usually relatively long, and the cruising range is relatively short, which has become the main factor restricting the popularization of electric vehicles. Under the premise that it is difficult to make a major breakthrough in the existing battery technology, replacing the battery pack has become the main way to solve the battery life problem of electric vehicles. That i...
