The novel storage battery plastic shell comprises a plastic shell body with a rectangular structure, wherein a partition plate is arranged in the plastic shell body and divides the interior of the plastic shell body into a plurality of battery tanks, damping clamping devices which are symmetrically arranged are arranged on the inner walls of two sides of the interior of each battery tank, energy absorbing devices which are symmetrically arranged are arranged on the opposite surfaces of one side of the exterior of the plastic shell body, and each energy absorbing device comprises an energy absorbing ring and an energy absorbing support, wherein the energy absorbing ring is arranged at the central position of the end surface of the plastic shell body, and the energy absorbing support is distributed to the periphery of the end surface of the plastic shell body in a radiation manner; the opposite surfaces of the other side of the outside of the plastic shell body are respectively provided with the reinforcing rib plate outer shell layers, and the battery pack is good in structural stability, but only suitable for a storage battery with a certain size, and poor in universality, and the size of the battery can not be adjusted.

Disclosure of Invention

The utility model aims at overcoming prior art can only adapt to the battery of a certain size, the poor shortcoming of commonality, but the not co-altitude battery of adaptation moulds the shell, but the commonality is good is moulded to the battery that provides a commonality.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a good battery of commonality moulds shell, includes drain pan and lid, be equipped with a plurality of baffles that are used for carrying out the subregion to the drain pan inside in the drain pan, the lid corresponds the position at the baffle and is equipped with the second baffle, the baffle is close to second baffle one side and is equipped with the slot, second baffle tip insert in its slot that corresponds and with slot sliding connection, drain pan lateral wall sliding connection has the side seal board, the side seal board upwards slides to lid one side back and lid rigid coupling, the side seal board bottom is connected with the spring, the one end that the side seal board was kept away from to the spring is connected on the drain pan. After the batteries are placed in the bottom shell, the batteries with different heights can be adapted by sliding the second partition plate up and down, so that the technical effect of adapting the batteries with different sizes is achieved; the side seal board prevents that the foreign matter from getting into in the drain pan, and the spring provides the pulling force, guarantees that the lid supports all the time and leans on the battery, live battery parcel.

Preferably, the bottom shell comprises a side plate, a slide rail is arranged on the side plate, the cross section of the slide rail is of a T-shaped structure, a slide groove matched with the slide rail is arranged on the side sealing plate, and the slide rail is located in the slide groove and is in sliding connection with the slide groove. The slide rail is T-shaped structure, and has the effect of limiting.

Preferably, a heat dissipation cavity is formed between the bottom end of the second partition plate and the bottom end of the slot at the lower portion of the slot, and heat dissipation holes are formed in the side face of the bottom shell at positions corresponding to the end portions of the heat dissipation cavity. When the battery is being used, there is a large amount of heats bottom shell inside, and the heat gets into the heat dissipation intracavity, and the louvre makes heat dissipation intracavity circulation of air, is convenient for dispel the heat.

Preferably, the inner side wall of the slot is provided with a sealing oil film. The sealing oil film prevents water in the heat dissipation chamber from flowing to the battery.

Preferably, the bottom shell comprises a side plate, a third partition plate is arranged at a position, corresponding to the side plate, of the cover, a second slot is formed in the side plate, and the end portion of the third partition plate is inserted into the second slot and is in sliding connection with the second slot. Increase the third baffle, further increase the utility model discloses a leakproofness.

Preferably, the side closure plates are bolted to the lid. The bolt is connected, and the installation and the disassembly are convenient.

Preferably, the number of the partition plates is equal to or less than five. When the number of the partition plates is too large, the installation is troublesome, the requirement on the process is high, and the production cost is high.

The utility model has the advantages that: the utility model provides a battery that the commonality is good moulds the shell, but the not co-altitude battery of adaptation, the commonality is good. In addition, the installation is convenient, the structure is simple, and the production cost is low.
