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 includes a fixing bracket, a limiting component and at least two locking components; the limiting component is arranged on the fixing bracket, and the limiting component is used for The battery box of the vehicle is limited; the locking component is connected with the fixing bracket, and the locking component is used to fix the battery box of the vehicle on the fixing bracket. The locking component includes a locking piece and a protrusion, and the protrusion is arranged on the locking on the side wall of the piece; the fixing bracket includes a first limiting hole, and a notch and a first limiting groove are provided on the side wall of the first limiting hole; the protrusion passes through the notch and engages with the first limiting groove; this The invention uses a limiting component to limit the position of the battery box to ensure that the battery box is installed in an accurate position; and a locking component is set to lock the battery box of the vehicle to prevent the battery box from falling off the fixing bracket and make the locking parts It is clamped with the fixed bracket to prevent the locking piece from falling off from the fixed bracket, which will affect the stability of the connection.

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. When the vehicle is in two states of rapid acceleration and sudden braking, there will be a large impact after the battery box is fixed and installed, and there will be damage to the battery box. Fixing is not stable, so the fixed structure cost of the existing battery box is relatively high, and the battery box in the prior art also has problems such as complicated installation and disassembly process and long time consumption
