Abstract

A battery mounting device for electric vehicle disclosed in the invention includes a first motor, Second motor, Fan body, fixing bar, Installation box, screw, Nut holder, lifting box, Battery case, mounting bracket and seal support plate. A first motor is installed at four corner positions on the bottom surface of the top plate of the mounting box, the rotating shaft of the first motor is fixedlyconnected with one end of the screw rod by a coupling. As that screw rod is driven to rotate by the first motor. As that screw rod transmission principle is use for controlling the rise or fall of thenut seat, so as to control the rise or fall of the lifting box, so as to control the ascending and descending of the battery box in the lifting box. The battery box can be self-unloaded, and the installation, disassembly and maintenance of the battery box are more convenient. The sealing support plate is fixed and stable by using the mounting bracket, the battery box is avoided to sway up and down when the vehicle is bumpy by using the fixing bracket, and the fan body is driven to rotate by the second motor, so as to cool the battery.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery installation device for electric vehicles. Background technique [0002] With the development of society, the popularity of new energy vehicles is getting higher and higher, and the utilization rate of electric vehicles in new energy vehicles occupies a dominant position. The batteries of some large electric vehicles are larger in size and heavier in weight. Under the bottom plate, when installing, it is necessary to raise the car bottom plate first, and then install the battery box. Due to the large volume of the battery box, it is more troublesome to install and disassemble. Contents of the invention [0003] The object of the present invention is to provide a battery installation device for an electric vehicle to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following techni...
