Abstract
The invention provides a battery case of a lithium battery pack, which relates to the technical field of battery cases, and solves the problem that the safety of the lithium battery pack of the prior art is relatively bad when in use. The battery case of lithium battery pack is arranged in a power supply box, and comprises a body and a roof cover which are made of alloy; the roof cover is provided with a chuck, and is fastened with the body through the chuck; a plurality of fixing holes are arranged in the bottom side of the body, and a plurality of locking holes of which the positions correspond to the fixing holes, are formed in the roof cover; and the outlet holes and the inlet holes, which are connected with each other, are formed in the roof cover. The battery case of lithium battery pack disclosed by the invention has the advantage of improving the use safety of the lithium battery pack.
Description
Technical field
The invention provides a kind of battery case, a kind of battery case of lithium battery group especially is provided.
Background technology
At present, lithium battery is widely used in portable electronics such as laptop computer, video camera, mobile communication with its distinctive performance advantage.And the high-capacity lithium battery of exploitation has begun to try out in electric automobile, and expectation will become one of major impetus power supply of 21 century electric automobile, and will be applied aspect artificial satellite, Aero-Space and energy storage.Along with the pressure of the environmental protection aspect in the in short supply and world of the energy, lithium battery is widely used in the electric motor car industry now, and the particularly appearance of LiFePO 4 material battery has more promoted development and the application of lithium battery industry.
The thing followed is that the lithium battery group in use exists larger safety problem simultaneously, own chemical characteristic due to lithium battery, to such an extent as to the lithium battery group is in use easily blasted, and the lithium battery group is when using as power supply, the lithium battery group directly is fixed in consumer unit usually, consumer unit adopts metal and plastics to be mixed usually, and the intensity of therefore tackling lithium battery group explosion time consumer unit is lower, and fail safe is relatively poor.
Summary of the invention
The present invention is directed to existing technology and have the problems referred to above, proposed a kind of battery case that can improve lithium battery group safety in utilization.
The present invention realizes by following technical proposal: a kind of battery case of lithium battery group, this battery case is arranged in consumer unit, comprise the body and the top cover that adopt alloy to make, described top cover has dop and is fastened on body by dop, it is characterized in that, described body bottom has several fixing holes, has several positions locking hole corresponding with fixing hole on described top cover, also has the wire hole that is interconnected and line concentration hole in the middle part of described top cover.
The battery case that alloy is made has higher mechanical strength, the blast of lithium battery group can be controlled in battery case.This battery case is realized sealing by the fastening of body and top cover, and the corresponding matching of fixing hole and locking hole further fixes body and top cover, wire hole is used for power line for the lithium battery group and passes and collect in the line concentration hole, avoids the staggered short circuit of power line of lithium battery group.
In the battery case of above-mentioned a kind of lithium battery group, described body comprises housing and the bottom that is fastened on housing bottom, and described fixing hole is opened on bottom.
Compared with prior art, the battery case of making by alloy is set in consumer unit, the lithium battery group is fixed in battery case, utilize the higher mechanical strength of battery case, when the lithium battery group is blasted, this battery case can be controlled at the impact that blast produces in battery case, has improved the fail safe that the lithium battery group is used.Simultaneously wire hole and line concentration hole can facilitate the power line of lithium battery group to draw, and avoid the power line short circuit that interlocks.

In figure, 1, top cover; 1a, dop; 2, body; 2a, housing; 2b, bottom; 3, wire hole; 4, line concentration hole; 5, fixing hole; 6, locking hole.
Embodiment
Be below specific embodiments of the invention, and by reference to the accompanying drawings technical scheme of the present invention be further described, but the present invention is not limited to these embodiment.
A kind of battery case of lithium battery group as shown in Figure 1, this battery case is arranged in consumer unit, comprise the body 2 and the top cover 1 that adopt alloy to make, described top cover 1 has dop 1a and is fastened on body 2 by dop 1a, described body 1 bottom has several fixing holes 5, have several positions locking hole corresponding with fixing hole 56 on described top cover 1, also have the wire hole 3 that is interconnected and line concentration hole 4 at described top cover 1 middle part.The battery case that alloy is made has higher mechanical strength, the blast of lithium battery group can be controlled in battery case.This battery case is realized sealing by the dop 1a of top cover 1 and the fastening of body 2, and the corresponding matching of fixing hole 5 and locking hole 6 and pass one by one fixing hole 5 and locking hole 6 with bolt, further body 2 and top cover 1 are fixed, wire hole 3 is used for power line for the lithium battery group and passes and collect in line concentration hole 4, avoids the staggered short circuit of power line of lithium battery group.As shown in Figure 2, body 2 comprises housing 2a and the bottom 2b that is fastened on housing 2a bottom, and described fixing hole 5 is opened on bottom 2b.
The battery case of making by alloy is set in consumer unit, the lithium battery group is fixed in battery case, utilize the higher mechanical strength of battery case, when the lithium battery group is blasted, this battery case can be controlled at the impact that blast produces in battery case, has improved the fail safe that the lithium battery group is used.Simultaneously wire hole 3 and line concentration hole 4 can facilitate the power line of lithium battery group to draw, and avoid the power line short circuit that interlocks.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has more used the terms such as top cover 1, dop 1a, body 2, housing 2a, bottom 2b, wire hole 3, line concentration hole 4, fixing hole 5, locking hole 6, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present invention; They are construed to any additional restriction is all contrary with spirit of the present invention.
