Abstract
The utility model discloses a battery steel shell structure which comprises a shell. The shell is composed of a bottom cap and a side wall, wherein the bottom cap and the side wall form a hollow cavity provided with an opening at the one end in a surrounding manner, and the opening is horn-shaped. The battery steel shell structure has the beneficial effects that through configuring the opening to be horn-shaped, a relatively large space is provided for a battery cell when the battery cell is placed into the shell, so that the battery cell is not likely to be damaged, and at the same time the production efficiency is improved; and in addition, the wall thickness of the side wall successively decreases from the opening to the bottom cap, and thus the space inside the shell is enlarged, and the battery capacity is increased.
Description
Technical field
The utility model relates to a kind of battery steel shell structure.
Background technology
At present, along with the expansion that Ni-MH battery is used, the demand of Ni-MH battery increases gradually.In producing the Ni-MH battery process, usually adopt pack into the mode of box hat of battery is produced.Yet, because the inwall internal diameter of the external diameter of battery and box hat is very approaching, therefore deviation is arranged slightly, very easily cause battery to damage or distortion, have a strong impact on the production efficiency of battery and reduced the quality of battery.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of battery steel shell structure is provided, and produces battery solve to adopt existing battery steel shell structure, the low and battery flimsy problem when packing into of efficient.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of battery steel shell structure comprises housing, and described housing is made of bottom and sidewall, and described bottom and sidewall surround the cavity that an end has opening, and described opening is bell mouth shape.
Further, the wall thickness of described sidewall is reduced successively by opening to bottom direction.
Further, the wall thickness of described opening one distolateral wall is 0.2mm, and the wall thickness of described bottom one distolateral wall is 0.13mm.
The beneficial effects of the utility model are, described battery steel shell structure is set to bell mouth shape by opening, thereby when battery is placed in the housing, for battery provides larger space, make battery not fragile, have improved simultaneously production efficiency; In addition, the wall thickness of sidewall is reduced successively by opening to bottom direction, has increased the enclosure interior space, has increased battery capacity.
Description of drawings
Fig. 1 is the structural representation of a kind of battery steel shell structure of the utility model;
In figure:
1, bottom; 2, sidewall; 3, opening.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of a kind of battery steel shell structure of the utility model; In the present embodiment, a kind of battery steel shell structure, comprise housing, described housing is made of bottom 1 and sidewall 2, described bottom 1 and sidewall 2 surround the cavity that an end has opening 3, and described opening 3 is bell mouth shape, and the wall thickness of described sidewall 2 is reduced successively by opening 3 to bottom 1 direction, the wall thickness of the distolateral wall 2 of described opening 3 one is 0.2mm, and the wall thickness of the distolateral wall 2 of described bottom 1 one is 0.13mm.
The utility model is simple in structure, be easy to realize, produce battery by adopting this kind structure, the efficient that battery is packed in battery steel shell improves greatly, and battery is not fragile, the wall thickness of sidewall 2 by opening 3 to bottom side 1 to reducing successively, thereby improved the inner space of housing, increased battery capacity.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
