Battery replacement power battery assembly of heavy truck

Abstract

The invention relates to the field of battery replacement power battery assemblies, in particular to a heavy truck battery replacement power battery assembly which comprises a battery pack locking frame, a battery replacement connector, a locking mechanism and a battery pack. The transfer pressing oil cylinder drives the pressing plate on the transfer pressing oil cylinder to rotate and press downwards, so that the pressing plate on the transfer pressing oil cylinder is pressed on the battery pack, the transfer pressing oil cylinder is a hydraulic cylinder, and compared with an air cylinder for pressing, the pressing of the battery pack is tighter, the battery pack is prevented from moving upwards, and the battery pack is prevented from moving upwards. Therefore, faults caused by the fact that a plug of the battery pack cannot be tightly inserted into the battery replacing connector are avoided, and if a pressing mechanism is replaced with a clamping mechanism, faults still occur due to the fact that a tilting gap is generated between the bottom of the battery pack and the top of a battery pack locking frame due to machining, and gas interruption occurs during actual pressing of an air cylinder are avoided.

Description

technical field [0001] The invention relates to the field of power-exchange power battery assemblies, in particular to a power-exchange power battery assembly for heavy trucks. Background technique [0002] With the gradual popularization of electric new energy vehicles, various technologies have also been improved and enhanced. For the battery pack set on the heavy truck, because the shape is too large, it is often necessary to use a locking mechanism to lock the battery pack. [0003] Chinese patent application number: CN202011070863.8; discloses an electric heavy-duty truck power exchange system, the solution is controlled by electric power, and then the battery pack is locked. [0004] This scheme has the following disadvantages: [0005] 1. In this solution, the battery pack is clamped in an electric way, so that the battery pack will not move up and down. However, since the bottom of the battery pack and the top of the battery pack locking frame will have a warped ga...

AI Technical Summary

Problems solved by technology

[0005] 1. This solution blocks the battery pack by electric means, so that the battery pack will not move up and down. However, due to the warping gap between the bottom of the battery pack and the top of the battery pack locking frame due to processing, the battery pack will not move up and down. After installation, the battery pack will shake on the battery pack locking frame, affecting the precise connection between the connector on the battery pack and the battery replacement connector

[0006] 2. And the device is not equipped with a pressing mechanism, so that the battery pack cannot be pressed on the battery pack locking frame
