Fixed battery quick changing mechanism for electric vehicle

Abstract

The invention relates to a fixed battery quick changing mechanism for an electric vehicle and overcomes the defect of inconvenience in replacing a battery due to an upward battery entrance and exit port in the existing battery frame. The fixed battery quick changing mechanism for the electric vehicle comprises a battery frame connected with a chassis frame of the electric vehicle. The battery frame is positioned below the chassis frame; a plurality of accommodating cavities for placing battery packs are arranged inside the battery frame; the lateral surface of the battery frame is open to form entrance and exit ports corresponding to the accommodating cavities; and battery frame covers capable of being opened and locked are arranged at the positions of the entrance and exit ports. The battery frame is fixed together with the chassis frame of the vehicle, so that after the batteries are arranged in the battery frame, the stability of the batteries can be improved and the batteries have low vibration; the battery fame is positioned below the chassis frame and cannot block the batteries from entering and exiting the battery frame, so that the batteries are convenient to replace; the battery entrance and exit ports of the battery frame are arranged at the side edges and below the chassis frame, so that the frame cannot block the entrance and exit ports and the batteries can be replaced by the entrance and exit ports; and the fixed battery quick changing mechanism for the electric vehicle has simple structure, is convenient to install and cannot occupy more space.

Description

technical field [0001] The invention relates to a battery installation part on an electric vehicle, in particular to a fixed electric vehicle battery quick-changing mechanism which is fixed on the chassis of the vehicle to facilitate battery replacement. Background technique [0002] With the world's energy shortage and environmental protection requirements, gasoline and diesel fueled vehicles have been subject to certain restrictions and impacts. Environmentally friendly and energy-saving electric vehicles have become an important branch of the automotive industry. Electric vehicles just meet the dual requirements of energy and environmental protection. Require. The key component of an electric vehicle is the battery. The reasonable layout and installation of the battery can provide greater power for the electric vehicle. In order to save the battery installation space, the battery is generally assembled into the battery frame in the existing electric vehicle. The frame is...

AI Technical Summary

Problems solved by technology

[0005] The invention solves the defect that the battery inlet and outlet in the existing battery frame face upwards, which causes battery replacement, and provides a fixed electric vehicle battery quick-changing mechanism with the battery inlet and outlet at the level, which is convenient for battery replacement

[0006] The invention also solves the defect that the existing battery frame is fixed to the bottom of the car and needs to be disassembled to replace the battery, which causes inconvenience in battery replacement. It provides a battery quick-change mechanism for electric vehicles, and a battery inlet and outlet are provided on the side of the battery frame, which is convenient. battery replacement

[0007] The invention also solves the defect that the existing battery frame uses a rotating structure to expose the battery inlet and outlet, which requires a large space and brings inconvenience to the installation of the battery frame. Under the car chassis, the battery replacement is more convenient
