Abstract

The invention relates to the technical field of new energy automobiles, in particular to a power battery pack fixing device. A plurality of battery pack mounting mechanisms are uniformly arranged on the outer side of the battery pack in the circumferential direction, positioning holes are formed in the battery pack mounting mechanisms, electric fasteners are arranged on the battery pack mounting mechanisms, and the electric fasteners are used for quickly fixing and separating the battery pack on an automobile bottom plate; the electric fastening device comprises a motor, a speed reducer, a screw rod, a wedge-shaped sliding block, a fixing support, a mounting pin, a reset piece, a positioning pin and a fixing claw, a shell of the motor is fixedly connected with the automobile bottom plate, and the output end of the motor vertically points to the ground. According to the technical scheme, the problems that in the prior art, the power battery assembly process is tedious, and when the power battery is in the short circuit or spontaneous combustion condition, the power battery cannot be automatically and timely separated from the automobile bottom plate, so that an automobile body is ignited, and losses are increased are solved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a power battery pack fixing device. Background technique [0002] Power batteries are the core components of electric vehicles. Lithium batteries, which are widely used at present, form current through internal electrochemical reactions to supply drive motors; with the large-scale popularization of electric vehicles, the safety requirements for electric vehicles are getting higher and higher. When batteries In the case of internal short circuit or thermal runaway, if the battery can be separated from the vehicle body in time, it will avoid burning and explosion of the vehicle, avoiding major accidents and personal injury; at the same time, the power battery pack is usually screwed under the vehicle body through several bolts , On-site assembly operations are cumbersome, affecting production beats. Contents of the invention [0003] In view of the deficiencies of th...
