Abstract

The invention discloses a battery frame fixing device of an automobile and the automobile. The battery frame fixing device is provided with a first fixing component, a second fixing component and a connecting rod assembly. Wherein in the fastening process, the first fixing component and the second fixing component can be connected through the connecting rod assembly in a clamping mode; for example, the locking component can be driven to enable the rod body to drive the clamping connector to be close to the first fixing component and clamped with the clamping part, the two components can be disassembled and assembled in the simple mode, and the automobile body frame can be directly used on the premise of changing the structure of the automobile body frame and has the advantage of being good in compatibility. Besides, according to the battery frame fixing device disclosed by the invention, a second connecting through hole with a spiral structure is formed in a second fixing component, and the spiral hole with the structure can further provide limiting force for the second fixing component in the axial direction of the rod body; therefore, the connector has the advantage of good connection reliability.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a battery frame fixing device of an automobile and an automobile. Background technique [0002] With the technological development of automotive power battery packs, the power capacity of power battery packs is also increasing. The traditional charging method is used to supplement the power, and the corresponding charging time is also increased. In order to shorten the time for electric vehicles to replenish power and improve the user experience Experience, you can directly replace the power battery pack by replacing the battery. [0003] In the existing power battery pack power exchange mechanism, the power exchange mechanism can generally be divided into two modes: bolt-type connection and snap-on connection. (1) Bolted connection method, the usual structure is: welded nut at the body end, and the power battery pack is fixed on the body end through the bolt and nut tightening connec...
