Abstract
The utility model discloses a square plastic shell of a heat-dissipating type lithium battery. The square plastic shell comprises a shell and an upper cover plate arranged at the upper part of the shell, wherein the upper cover plate is provided with a positive terminal, a negative terminal and a liquid charging hole; and the upper mouth of the shell is designed in a form of the transition from a slope to a plane. The front surface, the rear surface, the side surface and the bottom surface of the shell are all provided with reinforcing rib structures. The plastic shell of the lithium battery is square, so that the square plastic shell is suitable for various types of batteries, especially for the lithium-ion power battery which is made of polypropylene (PP) and can resist the corrosion of the electrolyte solution; the upper mouth outside the plastic shell is designed in a form of the transition from a slope to a plane, so that when the battery is sealed, the problems of poor tightness and undesirable appearance are solved, and when the battery is assembled, the problems of ventilation and heat dissipation are solved; the front surface, the rear surface, the side surface and the bottom of the shell all adopt the reinforcing rib structures, therefore, the strength of the shell is enhanced, and the ventilation and heat dissipation are improved on one hand, the weight of the shell of the battery is lowered on the other hand.
Description
Technical field
The utility model relates to battery case, specifically a kind of heat radiating type lithium battery square plastic casing.
Background technology
Since the lithium ion battery square plastic casing of polypropylene material was succeeded in developing, unique advantages such as light weight, moulding are simple, pollution-free because it has, recyclable utilization had been widely used in various lithium ion batteries at present.Though this battery plastics shell has its oneself characteristics, because reasons in structure, the welding effect of upper oral part is bad, and intensity is bad, so influenced its bulk life time.And the ventilation and heat of whole casing is poor.
The utility model content
The purpose of the utility model is the defective that exists to prior art; A kind of heat radiating type lithium battery square plastic casing is provided; Solve the technical problem of the bad and ventilation and heat difference of plastic battery housing welding effect that prior art exists, and when gaining in strength, alleviated the weight of entire cell shell.
The utility model solves the technical scheme that its technical problem adopted: a kind of heat radiating type lithium battery square plastic casing, and its structure comprises the upper cover plate of shell and shell upper, said upper cover plate is provided with positive terminal and negative terminal and offers liquid injection hole; Said shell upper oral part is a kind of by the design of chamfered transition to the plane.
The front and rear surfaces of said shell, side and bottom surface are provided with reinforcing rib structure.
A kind of heat radiating type lithium battery square plastic casing of the utility model is compared with prior art, has following beneficial effect:
The material that shell in the utility model adopts is polypropylene (PP), and the shell upper oral part is by the design of chamfered transition to the plane, the poor sealing that has caused when having solved battery seal, the problem of bad order, and ventilation and heat problem when having solved battery and assembling; Reinforcing rib structure is all adopted in shell front and rear surfaces, side and bottom surface, plays on the one hand and strengthens the casing rigidity effect, can alleviate the weight of battery container on the other hand, the more important thing is the effect that can play ventilation and heat.

Embodiment
Next explanation at length below with reference to Figure of description a kind of heat radiating type lithium battery square plastic casing of the utility model being done.
A kind of heat radiating type lithium battery square plastic casing, its structure comprises the upper cover plate 6 of shell 1 and shell upper, said upper cover plate is provided with positive terminal 3 and negative terminal 4 and offers liquid injection hole 5; Said shell upper oral part 7 is a kind of by the design of chamfered transition to the plane.The front and rear surfaces of said shell, side and bottom surface are provided with reinforcement 2 structures.The utility model battery plastics shell is square; Be fit to various size battery needs, particularly lithium-ion-power cell, its material is polypropylene (PP); But electrolyte resistance corrosion; The plastic housing external Design adopts upper oral part by the design of chamfered transition to the plane, the poor sealing that has caused when having solved battery seal, the problem of bad order, and ventilation and heat problem when having solved battery and assembling; Reinforcing rib structure is all adopted in shell front and rear surfaces, side, bottom, plays the effect of strengthening casing rigidity and ventilation and heat on the one hand, can alleviate the weight of battery container on the other hand.
The above embodiment is a kind of of the more preferably concrete execution mode of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection range of the utility model.
