Double-deck storage battery box body

Abstract

The invention discloses a double-deck storage battery box body which comprises a main body bracket, an upper fixed plate and a lower fixed plate, wherein batteries are placed on the upper fixed plate and the lower fixed plate respectively; a sliding plate is fixed on the inner side of the bottom end of the main body bracket; a plurality of holes are formed in the upper surface of the sliding plate, balls are mounted in the holes, and the lower surface of the lower fixed plate is in contact with the balls to enable the lower fixed plate to adopt a withdrawable structure; the fixed sleeve of a regulating mechanism is fixedly connected onto the bottom of the lower fixed plate, and the two ends of an adjustment lever are fixed onto a front end beam and a rear end beam; a limiting plate is fixed at the front end beam of the main body bracket and positioned at the front end of the lower fixed plate; a baffle plate is fixed on the lateral surface of the support frame of the main body frame. According to the invention, the arrangement of the lead-acid storage batteries for starting is changed to a stacking manner from a parallel manner, so that the arrangement space is effectively saved, the arrangement flexibility is improved, the distance between shafts is shortened at the same time to fulfill the purpose of light weight, and the center of gravity of a storage battery box body assembly is dispersed to reduce the bending moment to a fixed point so as to reduce the use of bolts.

Description

technical field [0001] The invention relates to a vehicle battery box, in particular to a power supply box for a heavy-duty truck lead vehicle. Background technique [0002] Most of the existing heavy-duty tractor power supply system layout schemes are two 12V batteries arranged side by side, which results in a minimum space occupied by the battery box assembly on the chassis of about 550mm. If the wheelbase is shortened and the weight of the vehicle is reduced, it often cannot meet the layout requirements of the vehicle, resulting in tight layout of parts on the chassis, affecting use and maintenance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-layer storage battery case which saves layout space. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A double-layer storage battery box, comprising a main body...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing power system layout schemes of heavy truck tractors are two 12V batteries arranged side by side, which causes the space occupied by the battery box assembly on the chassis to be at least about 550mm

If the wheelbase is shortened and the weight of the vehicle is reduced, it often cannot meet the layout requirements of the vehicle, resulting in tight layout of parts on the chassis, affecting use and maintenance, etc.
