Abstract
The utility model is related to the technical field of battery, discloses battery cap, including cover plate in the form of sheets, and the two side ends of cover plate upper surface form boss, installation table top is formed with boss respectively towards upper process；The following table of cover plate faces up concave shape into fluted, and groove is located at the underface of boss.In the battery cap that the utility model is provided, when cover plate is sealed in the upper end open of housing, the inside arrangement that the following table of cover plate faces down just to this housing, so, because the two side ends of the upper surface of cover plate form boss towards upper process, and the following table in cover plate faces up concave shape into groove, groove is located at the underface of boss, so, the inner chamber that formation is surrounded between cover plate and housing then includes the space of groove, and then the volume of increase inner chamber, more battery cores can be placed in inner chamber, and then increase the capacity of battery.
Description
Technical field
The utility model is related to the technical field of battery, more particularly to battery cap.
Background technology
As electronic product is increasingly minimized, portability, the utilization of battery is more and more extensive, because battery structure is simple
Single, easy to carry, discharge and recharge is easy to operation, is not influenceed by outside climatic and temperature, stable and reliable for performance, so existing
Very big effect is played for the various aspects in social life.
Battery cap includes cover plate, and cover plate is sealed on the upper end open of housing, so, shape is then surrounded between cover plate and housing
Into the inner chamber of battery, battery core can be placed in the inner chamber, certainly, the capacity of the capacity of battery core then with battery is directly related.
In the prior art, because the volume of the inner chamber of battery is too small, and then cause the capacity of battery smaller.
Utility model content
The purpose of this utility model is to provide battery cap, it is intended to which it is too small that solution has battery capacity in the prior art
Problem.
The utility model is achieved in that battery cap, including cover plate in the form of sheets, the both sides of the cover plate upper surface
End forms boss respectively towards upper process, and installation table top is formed with the boss；The following table of the cover plate face up concave shape into
Fluted, the groove is located at the underface of the boss.
Further, the two side ends of cover plate court respectively
Upper bent projection, forms the boss and groove.
Further, the perpendicular shape arrangement of the lateral wall of the boss.
Further, the madial wall of the groove is protruded towards inside grooves arc surfaced and arranged.
Further, it is provided with stepped hole in the boss.
Further, it is provided with location hole in the boss.
Further, the side end of the cover plate has the extension for extending outwardly, and the extension is located at the boss
Outside.
Further, the horizontal arrangement in the extension.
Compared with prior art, in the battery cap that the utility model is provided, when cover plate is sealed on the upper end open of housing
When upper, the inside that the following table of cover plate faces down just to this housing is arranged, so, because the two side ends of the upper surface of cover plate are dashed forward upward
Rise and form boss, and following table in cover plate faces up concave shape into groove, groove is located at the underface of boss, so, cover plate with
The inner chamber that formation is surrounded between housing then includes the space of groove, and then increases the volume of inner chamber, can be placed in inner chamber
More battery cores, and then increase the capacity of battery.
Brief description of the drawings
Fig. 1 is the cut-away illustration of the battery cap that the utility model embodiment is provided；
Fig. 2 is the enlarged diagram at the A in Fig. 1；
Fig. 3 is the schematic perspective view of the battery cap that the utility model embodiment is provided.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
Realization of the present utility model is described in detail below in conjunction with specific embodiment.
Referring to figs. 1 to shown in 3, for the utility model provides preferred embodiment.
The battery cap that the utility model is provided can be used in lithium battery, it is also possible to be used in other batteries, and
It is not limited only to one of which.
Battery cap includes cover plate 101, and cover plate 101 in the form of sheets, and dash forward upward respectively by the two side ends of the upper surface of cover plate 101
Rise, form boss 102, be formed with installation table top on boss 102, and following table in cover plate 101 faces up concave shape into fluted
101, the groove 101 is located at the underface of boss 102.
In the battery cap of above-mentioned offer, when cover plate 101 is sealed in the upper end open of housing, the following table of cover plate 101
The inside arrangement faced down just to this housing, so, because the two side ends of the upper surface of cover plate 101 form boss towards upper process
102, and following table in cover plate 101 faces up concave shape into groove 101, groove 101 is located at the underface of boss 102, so, lid
The inner chamber that formation is surrounded between piece 101 and housing then includes the space of groove 101, and then increases the volume of inner chamber, Ke Yi
More battery cores are placed in inner chamber, and then increases the capacity of battery.
Specifically, the two side ends of cover plate 101 bent projection upward respectively, and then form above-mentioned boss 102 and convex
The groove 101 of the lower section of platform 102.
The inner side of groove 101 protrudes arrangement towards the inside arc surfaced of groove 101, so, is easy to the bent projection of cover plate 101
Manufacture, is easy to the formation of boss 102 and groove 101.
In the present embodiment, the perpendicular shape arrangement of lateral wall of boss 102, so, it is ensured that the boss 102 of formation is cylindrical
Arrangement, is easy to boss 102 to coordinate with the connection of outer member.
Stepped hole 103 is formed with boss 102, the stepped hole 103 runs through the upper end of boss 102 and lower end, and then is formed
Through hole, so, using stepped hole 103, wears pole etc. in cover plate 101.
In addition, location hole 104 is provided with boss 102, so, when needing to install superior pole piece etc. on boss 102, then
It is embedded in location hole 104 using locating piece, and is embedded in superior pole piece, then can be realized between superior pole piece and boss 102
Positioning is installed.
In the present embodiment, the side end of cover plate 101 has the extension for extending outwardly, and the extension is located at boss 102
Outside, so, for cover plate 101, boss 102 will not be formed in the end of cover plate 101, be easy to the processing of boss 102.
Also, above-mentioned extension is horizontal to be disposed to extend.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
