Abstract
The utility model discloses a component for a metal foil to coat a battery capable of preventing rebounding. During cold punching forming of the metal foil, a V-shaped slot and a small circular hole are added to a bending part, so that the defect that battery products are difficult to assemble because of the large flexibility of a metal material is solved. The component for the metal foil to coat the battery capable of preventing rebounding provided by the utility model has the advantages that product sizes are easy to control, mechanical strength is high, safety and reliability are high, the contradiction between the battery capacity and volume is remitted, the service life of a product is prolonged, and the market competitiveness of the product is high.
Description
Technical field
The utility model relates to a kind of battery coated member, and particularly a kind of battery coated member that prevents resilience, belongs to cell package technical field.
Background technology
Mobile phone digital product appearance is more and smaller and more exquisite ultra-thin at present, is convenient for carrying, and from strength to strength, this just requires to continue a journey, and battery volume is less, capacity is larger for function.
But well-known, concerning lithium ion battery, battery capacity and volume have direct relation, battery volume is larger under normal circumstances, and battery capacity is also corresponding larger.In order to overcome the contradictory relation of capacity and volume, except battery core performance is improved, under more susceptible condition, be to be that battery core is reserved greater room to improve battery core capacity by improving PCAK technique, and then promote battery capacity.
In order to meet the requirement of mechanical strength and fail safe aspect of battery product, industry mostly substitutes plastic cement by metal forming and encapsulates lithium battery at present, and metal material is flexible larger due to himself, in addition battery product narrow space, while causing assembling product, easily there is stress resilience, be not easy to assembling.
Summary of the invention
In order to overcome the flexible defect that causes greatly assembling product difficulty of metal forming, the present invention by metal forming when the cold-punching molding, increase V-type groove 1 and small sircle hole 2 at metal forming bending part, to reduce stress resilience, more greatly cause battery product to assemble difficult defect because self is flexible thereby solved because of metal material.
Beneficial effect
1, solved metal forming bending after resilience stress large, assembling product difficulty, the problems such as the difficult to govern control of size, thereby improved product quality and acceptance rate;
2, improve mobile phone digital product battery capacity, solved the contradiction between capacity and volume;
3, increased the security reliability of mobile phone digital product battery;
4, the mechanical strength that has improved mobile phone digital product battery, has extended useful life.
Brief description of the drawings
Fig. 1 is the disclosed stereogram of the utility model;
Fig. 2 is the V-type groove enlarged diagram of the disclosed bending part of the utility model;
Fig. 3-5th, the disclosed encapsulation schematic diagram of the utility model.
Embodiment
First, by metal forming punch forming as shown in Figure 3, both sides bending part is evenly distributed with small sircle hole, increases V-type groove at bending part simultaneously, and object is that the time can more can ensure R angle square cun in order not flick after assembling battery core and glue shell.
Secondly battery core and glue shell, as shown in Figure 4, first metal forming be fixed on to tool, then left and right two parts raised, pack glue shell and battery core into, owing to all can not be encountered metal forming.This just need to raise enough large space, but metal forming is opened a business, distance is larger, just finally closes up and more easily flicks.Therefore, V-type groove and small sircle hole be exactly for reduce moulding and when assembling metal forming after opening a business, close up flexible, thereby convenient assembling.
Finally, as shown in Figure 5, then both sides metal forming is flattened, the product after completing is smooth, metal forming there will not be open, warp, distortion etc. is abnormal.Owing to having increased V-type groove and small sircle hole at bending part, the flexible of bending part greatly reduced, thereby after having solved metal forming bending, resilience stress is large, assembling product difficulty, the problems such as the difficult to govern control of size.
Above disclosed is only a kind of preferred embodiment of the present invention, the interest field that certainly can not limit the present invention with this, and the equivalent variations of therefore doing according to the claims in the present invention, still belongs to the scope that the present invention is contained.
Claims (3)
1. a power brick clad with metal foil member that prevents resilience, is characterized in that: comprise foil member body, the encapsulation bending part of described foil member is fluted.
2. the power brick clad with metal foil member that prevents resilience according to claim 1, is characterized in that: the encapsulation bending part of described foil member is porose.
3. the power brick clad with metal foil member that prevents resilience according to claim 2, is characterized in that: described hole is circular port.
