Described reinforcement is U-steel, and described U-steel is by horizontally disposed roof and is vertically connected on the sidewall of this left and right sides, roof bottom and constitutes, and the lower end of described sidewall outwards vertically turns down and forms horizontal bending edges.
Described postive stop baffle offers ventilating heat dissipating hole.
Described housing is rectangular housing, and described postive stop baffle has four pieces, and these four pieces of rectangular distributions of postive stop baffle.
The bottom of described housing is provided with the installing hole for connection body.
The utility model has the advantages that:
1, achieve the laminated multi-layer of battery module, save the space of car inner height.
2, the sidewall of base enclosure surrounding upwardly extends and protrudes from the top of cover plate, it is located at the postive stop baffle that cover plate is peripheral thus being formed to enclose, these postive stop baffles can not only limit the horizontal movement of upper strata battery module, and as the installation positionable wall of upper strata battery module, the location and installation of upper strata battery module can be facilitated.
3, the reinforcement arranged in base enclosure cover plate, substantially increases the structural strength of cover plate, effectively limits the up and down motion of upper strata battery module so that the anti-vibration of battery module and the ability of antidumping are greatly improved.
4, cover plate adopts the spaced apart structure of upper and lower plate body, and arranges channel-section steel reinforcement between upper plate body and lower body, thus reserving air communication channel between upper and lower two-layer battery module, improves heat dissipating state.
5, postive stop baffle offers hole, it is simple to the heat radiation of upper strata battery module.
6, two-layer module is individually highly all little, and assembly manipulation is convenient.Two-layer can be respectively mounted.
