Device for fixedly mounting lithium battery of new energy electric motorcar

Abstract

The invention discloses a device for fixedly mounting the lithium battery of a new energy electric motorcar. The device comprises a mounting base, wherein the middle point of the top of the mounting base is fixedly connected with a supporting base plate through a supporting spring; two sides of the top of the supporting base plate are fixedly connected with side mounting racks respectively; an upper pressing plate is arranged between the two side mounting racks; two sides of the upper pressing plate are fixedly connected with plug rods respectively; a through groove cooperatively used with each side mounting rack is formed in the position of the corresponding plug rod of each side mounting rack; and the side, close to each through groove, of the corresponding plug rod runs through the through groove and extends to the outside of the through groove. The device is simple in structure and convenient to mount, and most shaking force for the lithium battery generated by jolting when the motorcar drives in a poor road condition can be eliminated effectively, so that the battery is protected from being collided, the surface damage of the battery is avoided or the internal devices of the battery are avoided from being consumed, the service life of the battery is prolonged, the maintenance cost is reduced, and the using requirement of motorcars driving in multiple road conditions can bemet completely.

Description

technical field [0001] The invention relates to the technical field of new energy electric vehicles, in particular to a lithium battery fixed installation device for new energy electric vehicles. Background technique [0002] The composition of new energy electric vehicles includes: electric drive and control systems, mechanical systems such as drive force transmission, and working devices for completing predetermined tasks. The most widely used power source is lead-acid battery, but with the development of electric vehicle technology, lead-acid battery is gradually replaced by other batteries due to its low energy, slow charging speed, and short life. The main power sources under development are sodium-sulfur batteries, Nickel-cadmium batteries, lithium batteries, fuel cells, etc., the application of these new power sources has opened up broad prospects for the development of electric vehicles. Most of the traditional fixed installation devices for new energy electric vehic...
