Locking device for battery assembly and electric automobile

Abstract

The invention relates to a locking device for a battery assembly and an electric automobile. The locking device comprises a main shaft structure, a rotating structure and a fixed block structure. Themain shaft structure comprises a main shaft body, a first circumferential limiting structure, a clamping structure, a limiting shaft structure and a limiting structure, the clamping structure is usedfor being connected with an external driving mechanism, and the limiting shaft structure is used for being connected with the locking block; the rotating structure comprises a rotating cylinder body,a second circumferential limiting structure arranged on the inner wall surface of the rotating cylinder body and a spring clamped in the rotating cylinder body, the main shaft body penetrates in the rotating cylinder body, the first circumferential limiting structure is matched with the second circumferential limiting structure to limit the rotation of the main shaft body, and the spring is arranged between the rotating cylinder body and the limiting structure; and the fixed block structure comprises a fixed block body with a connecting hole, and the rotating cylinder body penetrates in the connecting hole. According to the locking device for the battery assembly and the electric automobile, no vibration noise exists in the use process, the structure is simple, use is convenient and reliable, and the implementing cost is low.

Description

technical field [0001] The invention relates to the field of quick locking mechanisms for battery boxes and vehicle bodies, in particular to a locking device for battery components and an electric vehicle. Background technique [0002] In order to solve the energy problem, my country is vigorously developing the electric vehicle industry. Users’ anxiety about the cruising range has always been a difficult problem to overcome. The use of quick-change technology can meet the customer’s requirements for the cruising range on the one hand, and on the other hand, it can also solve the operating user’s needs. Charging time anxiety. There are a variety of battery replacement methods in the prior art, such as the fast replacement method using bolt tightening, but there are defects in service life, and the buckle-type locking method has defects such as vibration and noise. [0003] Therefore, it is necessary to propose a structure with simple structure, convenience, reliability and l...
