Fast battery displacement device of battery compartment of large electric vehicle

Abstract

A fast battery displacement device of a battery compartment of a large electric vehicle structurally includes a working table with road wheels, which is used for storing the battery compartment in the middle and a matched control circuit. The fast battery displacement device of the battery compartment of the large electric vehicle is characterized in that the working table consists of a sliding table surface and a fixed table surface, the two table surfaces form a transverse sliding-fit structure with the aid of transverse sliding rails and a transverse driving mechanism, the upper end face of the sliding table surface is provided with two parallel longitudinal guide rails and a longitudinal linear driving mechanism which is arranged relative to the two parallel longitudinal guide rails in a matching mode, and the road wheels are positioned under the fixed table surface with the aid of a frame which is composed of a controllable lifting support column, a spherical hinge and an adjustable support rod. The fast battery displacement device of the battery compartment of the large electric vehicle utilizes a simple structure to dismount and replace a battery in the same station so that operating time and the manpower are saved to the largest extent; and utilizes the controllable lifting support column and the universal joint mechanism to achieve the random fine adjustment of the positions of the device and the electric vehicle to guarantee the perfect connection of the parallel longitudinal sliding rails arranged on the sliding table surface and the guide rails arranged in the battery compartment of the electric vehicle, which is used for storing a battery box.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for electric vehicles, and in particular relates to a quick power exchange device for a battery compartment of a large-scale pure electric vehicle. Background technique [0002] As a representative of new energy vehicles, electric vehicles have the advantages of economy and cleanliness; however, due to the limitation of battery capacity, the cruising range is low, which limits the promotion of electric vehicles. Increasing the capacity can extend the cruising range of electric vehicles, but it prolongs the charging time and increases the size and weight of the battery, making the process of replacing the battery more difficult. That is, when the on-board battery is low, you can go to the charging station to quickly replace a fully charged battery box. At present, the relevant policies formulated by the state stipulate that the battery replacement time should be controlled within 3 m...
