Storage battery shell convenient to assemble

Abstract

The invention discloses a storage battery shell convenient to assemble. The storage battery shell comprises a battery slot, a middle battery cover, and a protection cover plate, wherein the upper opening of the battery slot is connected with the middle battery cover in a matching manner by epoxy resin glue or heat sealing; stepping surfaces which are lower than the surface of the middle battery cover are arranged at two ends at the front side of the long side surface of the middle battery cover; terminal slots are symmetrically formed in the stepping surfaces at two ends; lead covers and terminal positioning slots are formed in the terminal slots; air discharge slots are formed in the middle of the middle battery cover and are internally provided with a plurality of air discharging openings; water overflowing openings are formed in the bottoms at the side walls of the air discharging slots; a water overflowing slot is formed in the periphery of the side walls of the air discharging slots in an annual manner; a notch is formed in a junction of the water overflowing slot and the middle battery cover; a circle of boss is formed around the protection cover; a plurality of clamping tables clamped with the water overflowing holes in the middle battery cover are formed on the inner wall of the boss. The storage battery shell convenient to assemble is simple in structure, is suitable for whole casting and welding of copper cover electrode columns, and is capable of achieving the mechanical automation production and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to an easily assembled accumulator case. Background technique [0002] From manual work to mechanized production is an inevitable trend of enterprise innovation. At present, the assembly of electric vehicle batteries usually adopts the method of manual welding busbars. Due to environmental protection requirements, manual welding is labor-intensive, low efficiency, and large quality fluctuations. The reason is that the company has been promoting mechanized casting and welding production, but there are still many problems in the mechanized battery casting and welding process currently used. For example, the battery terminals of electric vehicles are combined with copper core and lead-based die-casting. The bridge pole is cast-welded and the terminal pole is reserved for vacant positions, and then the terminal pole is welded by manual secondary assembly. The existing battery shell structur...

[0002] From manual work to mechanized production is an inevitable trend of enterprise innovation. At present, the assembly of electric vehicle batteries usually adopts the method of manual welding busbars. Due to environmental protection requirements, manual welding is labor-intensive, low efficiency, and large quality fluctuations. The reason is that the company has been promoting mechanized casting and welding production, but there are still many problems in the mechanized battery casting and welding process currently used. For example, the battery terminals of electric vehicles are combined with copper core and lead-based die-casting. The bridge pole is cast-welded and the terminal pole is reserved for vacant positions, and then the terminal pole is welded by manual secondary assembly. The existing battery shell structure prevents the casting and welding of the pole end pole. This method is time-consuming. laborious, affecting work efficiency

[0003] In addition, after the battery is charged and turned off-line, it is necessary to install an exhaust valve on the battery, and at the same time install a protective cover on the exhaust valve. The exhaust valve is an important part of the lead-acid battery, which directly affects the internal sealing reaction efficiency of the battery. Therefore, it is especially important to assemble the protective cover structure. It is necessary to press the exhaust valve with the protective cover. In the past, it was directly glued manually with glue to prevent the battery from being lifted and causing serious water loss, which would affect the performance and life of the battery.
