Battery box fixing device and vehicle

Abstract

The invention relates to the technical field of automobiles, in particular to a battery box fixing device and a vehicle. The battery box fixing device comprises a fixing support, a limiting assembly and at least two locking assemblies; the limiting assembly is arranged on one side of the fixing support and used for limiting a battery box of a vehicle. The locking assembly comprises a driving partand a locking part; the driving part and the locking part are both connected with the fixing support; the driving end of the driving part is connected with the locking part, the driving part is used for driving the locking part to rotate, and the locking part is used for fixing a battery box of a vehicle to the fixing support; According to the battery box fixing device, the limiting assembly is arranged to limit the battery box of the vehicle, and it is guaranteed that the battery box is installed at the accurate position; and the locking assemblies are arranged to lock the battery box of thevehicle, the Z direction of the battery box is restrained, and the battery box is prevented from falling off from the fixing support.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a battery box fixing device and a vehicle. Background technique [0002] At present, in the field of battery replacement for electric heavy trucks, the battery box adopts a fast-replacement structure, which can be quickly replaced in a dedicated battery replacement station. Under the action of the special battery replacement device, the battery box for battery replacement is removed and put into the charging station, and the fully charged battery box is installed on the electric heavy truck at the same time. The container is hoisted and removed under the action of special hoisting fixtures. The advantage is that the replacement of the battery box can be completed in a short time; the battery box is hoisted during the battery replacement process, and the hoisting fixture uses a winding steel cable to move up and down, and the horizontal accuracy is difficult to achieve high-p...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure sufficient mileage requirements for electric heavy-duty trucks, the total volume and weight of the heavy-duty truck batteries are too large. The vehicle is in two states of rapid acceleration and sudden braking, which will cause a large impact force after the battery box is fixed and installed. Therefore, the existing battery box The cost of the fixed structure is high, and the battery box in the prior art also has problems such as complicated installation and disassembly process and long time consumption
