Abstract

The application discloses a battery case and a battery case production mold for preventing bulging of the battery case. The battery case comprises two sidewalls, wherein reinforcing ribs are respectively arranged on the two sidewalls. Therefore, the battery case can prevent bulging deformation in the width direction by arranging the reinforcing ribs on the sidewalls of the battery case, thereby improving the strength of the battery case.

Description

A kind of battery case and a kind of battery case production mould that prevents the battery case bulging

Technical field

The application relates to the battery technology field, is specifically related to a kind of battery case and a kind of battery case production mould that prevents the battery case bulging.

Background technology

Along with the rapid increase of automobile storage battery demand, the competitiveness between storage battery manufacturing firm is also increasing, one of effective way that the accumulator product of low-cost, high-performance and good looking appearance is enhanced competitiveness beyond doubt.Yet, because raw-material price is constantly soaring, in order to reduce raw-material loss, to reduce costs, improve performance and outward appearance, normally accumulator product is carried out structure optimization and improvement.And be namely wherein one to structure optimization and the improvement of battery case.

Because battery case is simple in structure, so a lot of producer comes implementation structure optimization by the mode of the thick and heavy battery case of wall thickness being taken out glue or attenuate.If to carrying out attenuate with the battery case wall thickness of producing, and be to make the low-temperature startup performance of battery better, and be difficult for falling cream, accumulator pole group need to be assembled in battery case, fill tightlyer, usually utmost point group can produce certain precompression to the sidewall of battery case Width, so the problems such as insufficient strength, bulging distortion appear in the sidewall that the attenuate of battery case wall thickness will cause being close to utmost point group, in storage battery as shown in Figure 1, the bulging problem on deformation appears in two sidewalls 11 of its battery case and 12.And if when design with after the thick attenuate of glue, because the shrink material rate of producing battery case is large, make in the battery case cooling procedure, battery case inhomogeneous cooling, sidewall easily produce the situation of Inward deflection, as shown in Figure 2, two of

battery case sidewalls

21 and 22 indents in figure.Existing is to adopt the setting piece to improve the Inward deflection of battery case, as shown in Fig. 3-5, has six single lattice 31 as example take storage battery 30, and in Fig. 3, each single lattice 31 of battery case need to be put a setting piece 32, and the width of setting piece equals single lattice width.Although the method for this employing setting piece can avoid the distortion of battery case sidewall to produce harmful effect to assembling, it needs extra material manufacturing setting piece, and needs operation bidirectional, has reduced operating efficiency.

The utility model content

According to the application's first aspect, the application provides a kind of battery case that prevents bulging, comprises two sidewalls, and described two sidewalls have respectively reinforcement.Further, described reinforcement is netted.

According to the application's second aspect, the application provides a kind of battery case production mould that prevents the battery case bulging, and described mould has respectively and corresponding two mould side walls of two sidewalls of battery case, and described two mould side walls have respectively reinforcement.Further, described reinforcement is netted.

The application's beneficial effect is: because the sidewall of battery case has reinforcement, make battery case suppress the bulging distortion at the battery case Width due to the effect of reinforcement, thereby improved the intensity of battery case.

Embodiment

By reference to the accompanying drawings the application is described in further detail below by embodiment.

Embodiment 1:

As shown in Figure 6 and Figure 7, two sidewalls of the battery case 60 of a kind of embodiment of the application have respectively reinforcement 61, make battery case 60 suppress the battery case bulging at battery case Width (be illustrated as vertical) due to the effect of reinforcement 61, overcome the bulging problem on deformation, thereby improved the intensity of battery case.

In embodiment, reinforcement 61 is netted, and concrete web form can be multiple, can design web form based on the aesthetic appearance basis, thereby can improve the aesthetic feeling of product, has improved battery quality and the market competitiveness.

Embodiment 2:

The battery case production that prevents the battery case bulging of a kind of embodiment of the application is with in mould, and mould has respectively and corresponding two mould side walls of two sidewalls of battery case, is respectively equipped with reinforcement on these two mould side walls.The battery case that adopts this mould to produce, corresponding on its battery case sidewall also will have reinforcement, thereby overcome the battery case bulging problem on deformation of moulding due to the effect of reinforcement.In addition, owing to being improvement to mould, make battery case that mould thus obtains because there is not Inward deflection in the effect of reinforcement, solved existing because production process takes out to battery case the Inward deflection problem that glue causes, and do not need extra setting piece, and then need not simultaneously to increase cost in the intensity that improves the battery case product, reduced the cost of raw materials consumption.

In embodiment, reinforcement is netted, and concrete web form can be multiple, can design web form based on the aesthetic appearance basis, thereby can improve the aesthetic feeling of product, has improved battery quality and the market competitiveness.

The battery case of the embodiment of the present application and produce with the structural design of mould with implement simply, by increasing the side bead structures, improve the intensity of product and the aesthetic feeling of product, reduce the cost of raw materials consumption, improve battery quality and the market competitiveness.

Above content is the further description of the application being done in conjunction with concrete execution mode, can not assert that the application's concrete enforcement is confined to these explanations.For the application person of an ordinary skill in the technical field, under the prerequisite that does not break away from the application's design, can also make some simple deduction or replace.
