Power supply device for electric automobile

Abstract

The invention relates to a power supply device for an electric automobile. The power supply device comprises a power receiving side device (9) used for being connected with electric equipment and a power supply side device (8) used for being electrically connected with a power source, wherein the power receiving side device (9) can move close to the power supply side device (8) along with the electric equipment to supply power; the power receiving side device (9) comprises a base frame (91) and guiding rods (92) supported by a supporting arm (93) which is fixedly connected with the base frame (91); and a power supply plug device (94) which is electrically connected with the electric equipment through a tensile cable (940) is mounted on the guiding rods (92) in a sliding manner.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a power supply device for an electric vehicle. Background technique [0002] In occasions where power supply is required, it is often necessary to supply power to, for example, some motorized equipment, such as charging transport vehicles for indoor use and electric vehicles for transportation. In order to realize the electrical connection between the vehicle and the power source, it is often necessary to manually electrically connect the connector of the vehicle or the electric device to the power charging device. This often brings inconvenience to the operation and reduces the work efficiency in occasions where work efficiency is required to be high and where manual operation is inconvenient. Moreover, it is difficult to disconnect the charging in time, especially in the case where a mechanical connection is required to ensure charging reliability and safety, it is difficult to dis...

AI Technical Summary

Problems solved by technology

This often brings inconvenience to the operation and reduces work efficiency in occasions where work efficiency is high and where manual operation is inconvenient.

And it is difficult to achieve timely charging disconnection, especially in the occasions where mechanical connection is required to ensure charging reliability and safety, it is difficult to disconnect both electrical and mechanical connections

And some ways of directly mechanically connecting the plug of the electrical equipment to the power supply through the motorized movement of the electrical equipment can solve the problem of fast electrical connection, but it has a high accuracy for the mechanical movement positioning of the electrical equipment. Requirements, it is difficult to meet the position error fault tolerance problem caused by inaccurate stop position of electrical equipment
