Description

A kind of battery packaging structure

Technical field

The utility model relates to a kind of battery packaging structure.

Background technology

At present; the built-in injecting glue battery design of polymer Li-ion scheme mainly is that electric core is wrapped up a kind of steel disc (can satisfy the face shaping of customer requirement and increase the hardness of electric core); requirement according to client's appointment designs portion's shape end to end then; to form one with electric core, protective circuit, and be placed at last and carry out injection moulding in the mould that designs.As shown in Figure 1, moulding steel disc 15 in electric core 14 outer wrap, the head sheet has a baffle 12 for 11 times.During injection moulding, inject injecting glue material 13, self-contained battery structure in baffle 12 bottoms.

This kind design exists that equipment has high input (injection molding machine and injection mold), operation is loaded down with trivial details and the unmanageable problem of quality, along with the internal battery constantly trend of development and the pressure of cost, needs the more reasonable better organization plan of design.

Therefore, prior art awaits improving and development.

The utility model content

The purpose of this utility model is to provide the battery packaging structure that a kind of operation is easier, cost is low.

The technical solution of the utility model is as follows:

A kind of battery packaging structure comprises the steel disc of plastic parts, baffle, electric core and parcel electricity core, and wherein, there is gear described plastic parts lower end, snaps in described steel disc; Described baffle is fixed in the described plastic parts.

Described battery packaging structure, wherein, described baffle is fixed in the described plastic parts by metallic pin.

Described battery packaging structure, wherein, porose position is used to insert described metallic pin on the described plastic parts.

Described battery packaging structure, wherein, the quantity of position, described hole is 2.

Described battery packaging structure, wherein, there is pad the lower end of described baffle, with the lug welding of described electric core.

Described battery packaging structure wherein, also comprises label paper, and described label paper wraps up entire cell.

Described battery packaging structure, wherein, described plastic parts upper end has and the adaptive recess of described label paper shape.

Adopt such scheme, the utility model can obtain following effect by this plastic parts of design:

1. reduced Shooting Technique, process structure is simplified;

2. production operation is convenient, fast, has improved operating efficiency;

3. the production cost and the cost of raw material have all obtained reduction;

4. be convenient to do over again, quality related cost also greatly reduces.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.

The utility model changes present organization plan by plastic parts structure of design and metallic pin on battery.

Electrostrictive polymer core 24 head constructions behind the parcel steel disc 25 shown in Fig. 2 a, 2b, this moment is in all gapped space of six faces of head position of electric core 24, can utilize the clearance space between steel disc 25 and the electric core 24, designing what a plastic parts 21 snaps in this clearance space, and utilize 25 pairs of plastic parts 21 of steel disc of forming to position, shown in Fig. 3 a, 3b.

Fig. 4 a, 4b are the explosive view of battery assembling; wherein; after electric core 24 assembles with steel disc 25; the lug 1 of electric core 24 and the pad 2 in the baffle 22 are welded; again according to tell about above plastic parts 21 is buckled well with moulding steel disc 25; gear 3 in the plastic parts 21 contacts with steel disc 25 inwalls at this moment, makes steel disc 25 realize fixing plastic parts 21.

Anticipate as shown in Fig. 3 b, the baffle 22 of this moment is in vacant state, need fix.For this reason, position, hole 4 is set and is used for placing corresponding with it metallic pin 26 in plastic parts 21.As shown in Fig. 5 a, 5b, metallic pin 26 runs through plastic parts 21 by position, hole 4, and screens baffle 22 can not move baffle 22 in the head plastic parts.The quantity of metallic pin 26 is not limit, and can be as shown in the figure 2, can be 1 or several yet; Shape is not limit yet, can be to sell directly to households, and also can be screw, rivet etc.

With label paper 23 the entire cell structure is wrapped up at last, wherein protuberance 6 places in the label paper 23 just in time cover recess 5 places in the plastic parts 21, after parcel is good, can guarantee that plastic parts 21 can not do any moving, and make its location.The effect of recess 5 is to make label paper 23 parcels tightr, does not produce displacement behind the parcel, therefore only needs adaptive with label paper 23.The quantity of recess 5 can be as shown in the figure 2, also can be several; As long as can make fixedly plastic parts 21 of label paper 23, shape size and position are not limit yet, as being grid shape, trellis etc.

As above promptly finished the assembling of battery.

The utility model has the plastic parts of gear by design, can directly snap in steel disc and fix; For fixing baffle, design porose position on this plastic parts, can insert metallic pin baffle is stuck in the plastic parts; Simultaneously,, further plastic parts is fixed, obtained firm battery packaging structure by the parcel of label paper.The encapsulation process of battery need not injection moulding, and operation is simple, accessory is easily replaced, cost is low, can reach satisfied fixed effect simultaneously.

Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection range of the utility model claims.
