Description

Technical Field

[0001] The invention relates to the technical field of lead-acid batteries, in particular to a battery shell of a lead-acid battery. Background Art

[0002] At present, when producing 65AH automotive battery products, because the size of the original product cell shell remains unchanged, a new type of plate is added. The position of the new plate not only changes the position of the ear from the side ear to the middle ear, but also changes the height of the plate; after the height change, because the position of the product's pole and bus remains unchanged, it is necessary to increase the height at the bottom of the car, and the height of this part is the height of the reduced plate; from the perspective of cost and efficiency, the improved cell shell adds 6 high saddles at the bottom of the original cell shell. The structure of the high saddle is sheet-mounted, with a thickness of 3mm, and rises along the bottom toward the notch; the height of the saddle is determined according to the height of the plate. After adding the saddle, a cross-shaped passage is formed at the saddle and the partition wall after the glue is added at the bottom of the cell shell. The amount of glue increases at this position. If the exhaust is not smooth during the cooling process, it is easy to form pores or even perforations. If there are perforations at the bottom of the partition wall of the cell shell, the battery will be scrapped after production. In order to solve this problem, a new saddle structure is invented to solve the above perforation problem; The locking method of the top cover and the shell of the lead-acid battery case mentioned above is to lock them by bolts.
