Description

Battery package shell subassembly

Technical Field

The utility model relates to a battery package field specifically is a battery package shell subassembly.

Background

The battery pack is generally a generic term for a protective case in which the battery pack is attached to the outside of the battery pack. Some electronic products are not enough in self-contained battery capacity, and need to wear an external battery with larger capacity, and a battery pack is born from the battery pack, and a shell attached to the outside of the battery pack is generally called a battery pack shell.

A battery pack assembly including an upper case and a lower case has been disclosed in the prior art. The upper shell is provided with a buckle, the lower shell is provided with a clamping groove, and the buckle and the clamping groove are movably clamped together, so that the upper shell and the lower shell can be movably clamped together. However, since the flexibility of the buckle makes the upper case or the lower case easily disassemble the housing assembly when external force is applied, the utility of the battery pack is greatly limited.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem to the current situation of prior art, and provide a battery package shell subassembly.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: it is proposed a battery pack housing assembly comprising:

the upper shell is provided with a top wall formed at the top of the upper shell and a first side wall formed at the side of the upper shell, and a buckle is arranged at the bottom end of the first side wall in a direction far away from the top wall;

a lower case detachably mounted at a bottom of the upper case and having: a second sidewall formed at a side of the lower case; a catching groove formed at an upper portion of the second sidewall; a stopper formed on an inner wall of the lower case;

the movable buckle is clamped in the clamping groove, the back face of the buckle is abutted to the stop block, and the buckle is prevented from being separated from the clamping groove.

In the above battery pack case assembly, the stopper is formed to extend from the bottom of the lower case in the height direction of the lower case.

In the battery pack case assembly, a chamfer is arranged on one side of the stop block close to the upper end of the lower case.

In the battery pack case assembly, the cross section of the clamping groove is rectangular, trapezoidal or parallelogram, and the clamping groove penetrates through the second side wall.

Compared with the prior art, the utility model has the advantages of pass through, the inner wall of casing increases the dog and prevents buckle and draw-in groove separation under the effect of external force down for go up the casing and down between the casing block more firm, finally make the battery package shell no longer receive service environment's restriction.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and fig. 2, the present invention provides a battery pack housing assembly, comprising: an upper case 10 and a lower case 20.

The lower case 20 is detachably mounted to the bottom of the upper case 10. The detachable installation mode provides convenience for the installation of the whole battery pack battery. And when in subsequent repair or replacement, only the upper and lower shells need to be disassembled to replace the battery pack in the battery pack, so that the whole battery pack does not need to be replaced, and the maintenance and replacement cost of the battery pack is well reduced.

As shown in fig. 3 and 4, the upper housing 10 has a top wall at the top and a first side wall at the side, and a latch 11 is provided at the bottom end of the side wall in a direction away from the top wall. The lower shell 20 is provided with a second side wall formed by the side face, a clamping groove 21 arranged on the upper portion of the side wall and a stop block 22 arranged on the inner wall, when the buckle 11 is clamped in the clamping groove 21, the back face of the buckle 11 abuts against the stop block, and thus under the condition that the upper shell 10 or the lower shell 20 is subjected to external force, the stop block 22 blocks the plastic deformation of the buckle 11, so that the separation of the buckle 11 and the clamping groove 21 is blocked.

As a preferable aspect of the present invention, the stopper 22 is formed by extending from the bottom of the lower case 20 along the height direction of the lower case 20, and such a design enables the stopper 22 to have the highest strength, and the manufacturing process of the lower case 20 can be simple. Of course, in the case of making the stopper strong enough to block the buckle 11, the length of the stopper 22 near the bottom of the lower case 20 can be reduced appropriately, which can achieve the effect of saving material and further saving manufacturing cost.

As an optimized scheme of the utility model, one side that dog 22 is close to casing 20 upper end down is equipped with the chamfer, and this chamfer can be the oblique angle also can be a fillet, and like this when casing joint under and at last, chamfer and buckle 11's tip contact on the dog 22 for buckle 11 is better scratch into in the middle of the draw-in groove 21.

As another preferred embodiment of the present invention, the interface of the slot 21 may be a rectangle, a trapezoid or a parallelogram, and other irregular shapes may also be acceptable as long as the purpose of fastening with the buckle 11 can be achieved, but the regular shapes such as a rectangle, a trapezoid or a parallelogram may make the production process of the lower housing relatively simple.

Preferably, the clamping groove 21 penetrates through the second side wall, so that the maximum clamping area of the buckle 11 and the clamping groove 21 can be achieved without changing the wall thickness of the upper shell 10 and the lower shell 20, and the lower shell 20 of the scheme is processed in the simplest manner. Of course, the locking slot 21 may be a blind hole formed on the second side wall, which increases the difficulty of processing the lower housing 20, but provides a more complete and beautiful appearance of the entire housing assembly.

The greater the number of the hooks 11 and the slots 21, the more firmly the upper and

lower cases

10 and 20 are hooked, but correspondingly, the manufacturing cost and the complexity of the manufacturing process of the upper and

lower cases

10 and 20 are increased. Preferably, the utility model discloses what chooseed for use is the joint of three group's buckles 11 and draw-in groove 21.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
