Replacing device for battery boxes of electric vehicle

Abstract

The invention provides a replacing device for battery boxes of an electric vehicle, which is used for taking down one undercharged battery box from the vehicle, conveying the undercharged battery box to a battery transfer rack or conveying one fully-charged battery box on the battery transfer rack, and mounting the fully-charged battery box on the vehicle. The battery boxes don't need to rotate when being replaced by the device, so that replacing time is saved, and the problem that a large rotating space is needed for replacing the battery boxes is solved. The device comprises a translational device, a mechanical arm and a lifting device, the mechanical arm has a bidirectional moving function, namely, the mechanical arm is capable of extending along the vehicle direction and extending along a battery rack, and two rows of rollers are arranged on the mechanical arm so as to be convenient for drawing off the battery boxes. The device has the advantages that the device consisting of various conventional products is lower in manufacture cost, small in size, flexible in action and fine in universality, the required moving passage width is obviously decreased, and occupied area for replacing is saved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a battery box replacement device for electric vehicles. Background technique [0002] Energy conservation, environmental protection, mitigation of energy crisis, improvement of human living environment, and containment of atmospheric conditions are the primary issues facing the sustainable development of the automobile industry. Electric vehicles use electricity as the main energy source, and have the advantages of low emissions and high energy efficiency, and are the main choice to replace fuel vehicles. In the context of increasingly prominent global energy and environmental problems, the development of electric vehicles has become an important way to get rid of dependence on oil resources, achieve energy conservation and emission reduction, and alleviate energy and environmental problems. [0003] There are currently three energy supplement modes for electric vehi...

AI Technical Summary

Problems solved by technology

This device is suitable for vehicles whose body height changes at any time when the battery box is picked and placed, and can solve the impact of the change of body height on the replacement of the battery box; and the battery box only needs translation during the entire replacement process, which improves the reliability of the replacement process sex
