Abstract

The invention provides a locking device, a battery pack assembly and a vehicle. The locking device comprises a connecting shaft, a limiting sleeve, a sleeve and a first baffle; a first limiting structure is arranged in the circumferential direction of the connecting shaft, a second limiting structure is arranged on the inner wall of the limiting sleeve, a first guide structure is arranged on the outer wall of the limiting sleeve, and a second guide structure is arranged on the inner wall of the sleeve; the connecting shaft and the limiting sleeve are slidably connected and coaxially assembled, and the limiting sleeve and the sleeve are slidably connected and coaxially assembled; when the limiting sleeve slides to a locking position relative to the sleeve, the first limiting structure is clamped with the second limiting structure; when the limiting sleeve slides to the unlocking position relative to the sleeve, the first limiting structure is separated from the second limiting structure; the first guide structure is in sliding connection with the second guide structure; the first baffle is fixedly connected with the sleeve so as to limit the limiting sleeve to be separated from the sleeve. The locking device disclosed by the invention can be reliably used for a long time under the environment that the battery pack is frequently disassembled and assembled and the vehicle is bumpy.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a locking device, a battery pack assembly and a vehicle. Background technique [0002] In recent years, with the rapid development of the domestic automobile industry, it is facing severe challenges in the field of energy and the environment. The country has listed new energy and new energy vehicles as one of the strategic emerging industries supported by the state, and pure electric vehicles have entered a period of rapid development. As the power source and the most fundamental component of electric vehicles, power batteries are the key factors affecting the development of electric vehicles. Charging anxiety, cost anxiety and mileage anxiety have always been troubles for users of new energy vehicles when traveling. The most effective way to solve the above problems is to quickly replace the battery pack, which requires that the quick-change battery pack device can be used r...
