Abstract
The invention discloses a battery steel shell structure. The battery steel shell structure comprises a shell, wherein the shell consists of a bottom cover and a side wall; and a cavity is enclosed by the bottom cover and the side wall, and a horn-shaped opening is formed at one end of the cavity. The battery steel shell structure has the advantages that by forming the horn-shaped opening, when the battery cell is placed into the shell, a large space is provided for a battery cell, so the battery cell is difficult to damage, and production efficiency is improved; and moreover, the thickness of the side wall is gradually decreased along the direction from the opening to the bottom cover, the internal space of the shell is enlarged, and battery capacity is improved.
Description
Technical field
The present invention 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.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of battery steel shell structure is provided, produce battery solve to adopt existing battery steel shell structure, the low and battery flimsy problem when packing into of efficient.
The objective of the invention 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.
Beneficial effect of the present invention is, 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, so that battery is not fragile, 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 present invention;
Among the figure:
1, bottom; 2, sidewall; 3, opening.
Embodiment
Further specify technical scheme of the present invention 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 present invention; 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 described opening 3 one distolateral walls 2 is 0.2mm, and the wall thickness of described bottom 1 one distolateral walls 2 is 0.13mm.
The present invention is simple in structure, be easy to realize, produce battery by adopting this kind structure, the efficient that battery is packed in the 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 invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
