Double layer battery box

Abstract

The invention discloses a double-layer storage battery box, which comprises a main body bracket and an upper and lower fixing plate. Batteries are respectively placed on the upper fixing plate and the lower fixing plate. A sliding plate is fixed on the inner side of the bottom end of the main body bracket, and several holes are opened on the upper surface of the sliding plate. Balls are housed in the holes, and the lower surface of the lower fixing plate is in contact with the balls. Make the lower fixing plate a withdrawable structure. The fixing sleeve of the adjusting mechanism is fixedly connected to the bottom of the lower fixing plate, and the two ends of the adjusting rod are fixed on the front and rear beams. A limit plate is fixed on the front end beam of the main body bracket at the front end of the lower fixing plate, and a baffle plate is fixed on the side of the support frame of the main body bracket. In the present invention, the lead-acid batteries for starting are changed from a side-by-side arrangement to a stacked arrangement, which effectively saves the arrangement space and improves the arrangement flexibility. At the same time, the wheelbase can be shortened to achieve the purpose of light weight, and the overall battery box is dispersed. The formed center of gravity reduces the bending moment on the fixed point, thereby reducing the number of bolts used.

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.
