Abstract

The invention aims to provide a battery fixing device for an electric automobile, which is convenient to mount and disassemble/assemble and is firm for fixation. The battery fixing device for the electric automobile comprises a battery tray, a battery press plate, a screw with thread at the top end and a nut matched with the screw; a through hole for fixing is formed on a bottom plate of the battery tray; through holes are formed on the opposite side walls of at least two sides of the battery tray; a through hole is formed on the battery press plate; the bottom end of the screw is bent to form a hook; the screw passes through the through hole on the battery press plate; the hook at the bottom end of the screw is inserted into the through holes on the side walls of the battery tray; and the top of the screw is compacted and fixed with the battery press plate through the nut. The battery fixing device of the electric automobile has simple structure and can be formed by punching through a metal plate with relatively low cost; and moreover, the battery is convenient to mount and disassemble/assemble and subject to multidirectional limit in the device, thus realizing firm fixation.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle manufacturing, and in particular relates to a battery fixing device for the electric vehicle. Background technique [0002] Electric vehicles use batteries as power sources to achieve zero emissions and zero pollution. This is the direction and inevitable trend of the future development of automobiles. At present, the power batteries used in electric vehicles are relatively heavy, generally around 60kg. If there is no good fixing device, the power The battery may move while the car is running, causing an accident. In addition, the service life of the power battery is generally shorter than the service life of the car, so the electric car will inevitably replace the battery during its use, and unreasonable battery fixing devices will make the handling and disassembly of the battery more difficult. Contents of the invention [0003] The object of the present invention is to provide a bat...
