Technical Field

The utility model relates to a non-road vehicle lithium electric power system technical field, concretely relates to electric fork truck battery package box.

Background

At present electric fork-lift adopts the power supply of individual layer battery package more, and the power supply volume is limited, and live time is shorter, and the space is great on actual electric fork-lift's the battery package mounted position direction of height, and the space does not obtain effectual utilization, and space utilization is low, has consequently appeared bilayer structure's battery package, has strengthened the utilization ratio in space when having improved the power supply volume, but the bilayer structure's of battery package among the prior art support rigidity is not enough, produces low frequency resonance easily.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides an electric fork-lift battery package box has strengthened the intensity of battery package box, has avoided low frequency resonance's production.

The utility model provides an electric fork-lift battery package box, includes box curb plate, box front panel, box upper cover and box bottom plate to enclose and close and constitute the box, its characterized in that install lower floor's module fixed plate and upper module fixed plate in the box, lower floor's module fixed plate and box bottom plate fixed connection are provided with an upper supporting beam between lower floor's module fixed plate and the upper module fixed plate.

Furthermore, the back of the upper-layer module fixing plate is provided with a longitudinal reinforcing beam.

Furthermore, the upper-layer supporting beam comprises a transverse supporting beam and a longitudinal supporting beam, the transverse supporting beam is fixedly connected with the side plate of the box body, and the longitudinal supporting beam is fixedly connected with the transverse supporting beam and the lower-layer module fixing plate.

Furthermore, a fan mounting hole and a heat dissipation hole are formed in the side plate of the box body.

Furthermore, the box upper cover be the L type, including back plate and upper plate, be equipped with the bending on the upper plate.

Furthermore, a battery control system mounting plate is arranged on the longitudinal supporting beam.

The utility model can effectively utilize the installation space of the battery pack and install more modules, thereby increasing the power supply capacity of the battery pack; meanwhile, the strength of the box body is enhanced, and low-frequency resonance is avoided.
