Abstract

The invention relates to a battery case lock mechanism of an electromobile. The battery case lock mechanism is composed of a rocking handle, a transmission shaft assembly, a fixing flange, a crank, a connection rod assembly, a hinge block and a lock core assembly. Torque is transmitted through a slider crank mechanism so as to achieve displacement changing of a lock core; the capacity for bearing axial load is achieved through a limiting design of a transmission shaft; locking or unlocking of the lock core of the battery case and sliding in or sliding out of an automobile chassis from the battery case are achieved by twisting, pushing or pulling the rocking handle, and combination or separation of the battery case and the automobile chassis is achieved. The battery case lock mechanism meets requirements for being multifunctional and capable of bearing axial and radial load of a lock, simultaneously has the advantages of being high in reliability, precise in mechanical structure and capable of being used in automatic and manual operation and meeting the requirements for fast jointing and separation between the battery case and the electromobile.

Description

technical field [0001] The invention relates to a battery box lock mechanism, in particular to a side battery box lock mechanism for an electric vehicle. Background technique [0002] The pollution of the living environment is increasing day by day, and the harmful emissions of ordinary vehicles are increasing day by day, making electric vehicles the leading role in the new energy vehicle industry. The popularization and application of quick replacement battery technology has enabled batteries to be accessed and placed as easily as fuel, and basically eliminated people's anxiety about the low battery life of electric vehicles. In the rapid battery replacement technology, the installation and disassembly of the battery box requires the use of a battery box lock mechanism with reliable performance and reasonable structure, so that the battery box and the electric vehicle can be quickly and safely locked and opened. Although the locking mechanism in the state of the art has pr...
