Abstract
The utility model discloses a kind of washers for lithium ion battery cover, including matrix, the bottom surface of described matrix is inwardly formed the first boss of the rectangular type in section, the second boss of the rectangular type in section is provided on the inside of first boss, is connected at the top of the vertical wall middle and upper part of first boss and the vertical wall of second boss by dowel；Resistance material muscle is formed in the middle part of described matrix inner wall；The first boss top surface forms bulge loop.The step of this base bottom is set as double step type structure; protect the small aluminium flake in step; the stress degree of small aluminium flake can not only be slowed down during battery seal; and even if small aluminium flake has a degree of deformation; small aluminium flake is effectively prevented to be come off by the extruding at slot rolling R angles and cause scrapping for battery; it efficiently avoids battery R angles to contact with the direct of small aluminium flake, the positive and negative anodes short circuit of battery can be prevented well.
Description
Technical field
The utility model belongs to a kind of battery cap sealing ring, and in particular to a kind of pad for lithium ion battery cover
Circle.
Background technology
The appearance of battery is the life of our mankind, amusement and work provide important power supply guarantee.With society
Development and the progress of human civilization, one-shot battery due to environment pollution, capacity is low, usage time is short the shortcomings of gradually will be by
The secondary cell of the advantages that superseded instead pollution-free, capacity is big, service life is long, wherein lithium battery are distinctive certainly
Body structure and performance are widely applied to every field, as laptop, mobile power, electric tool etc. are exactly therein
It represents.
Cell safety combination cover cap is the most important safety guarantee component of lithium battery, and the structure and production technology of itself are straight
The performance of lithium battery is connect or affects indirectly, the wherein structure of sealing ring can not only affect the sealing effect of battery, also hold
Easily cause small the coming off for aluminium flake of Laser Welding in battery manufacture sealing process and be directed at scrapping for battery, it is potential can also cause explosion,
Fire etc..Sealing ring in existing cell safety combination cover cap is primarily present problems with：Sealing ring is combined with combining material
Afterwards it is vibrated, squeeze and be oppositely positioned etc. due to, material is easy to come off, and rework rate is big, working efficiency reduces, virtually
It increases manufacturing cost；Easily in battery seal, pressure applied is squeezed sealing ring by slot rolling R angles, can directly be conducted
It gives Laser Welding small aluminium flake, be directed at small aluminium flake deformation or directly come off, be finally directed at scrapping for battery；The small aluminium flake of finished battery takes off
Positive and negative short circuit can be directly directed at and cause the immeasurable loss such as the explosion of battery, fire by falling.
Utility model content
The utility model proposes that the purpose is to provide one kind to be used in order to overcome shortcoming in the prior art
The washer of lithium ion battery cover.
The technical solution of the utility model is：
A kind of washer for lithium ion battery cover, including matrix, the bottom surface of described matrix is inwardly formed section in straight
The first boss of angle-style, is provided with the second boss of the rectangular type in section on the inside of first boss, in the vertical wall of first boss on
It is connected at the top of the vertical wall of portion and second boss by dowel；Resistance material muscle is formed in the middle part of described matrix inner wall；Described first is convex
Countertop forms bulge loop.
Described matrix top surface is intilted inclined-plane.
The first boss it is always open towards on the outside of matrix.
The second boss it is always open towards on the inside of matrix.
The dowel tilts upward setting from first boss to second boss.
The second boss top surface is less than first boss top surface, higher than first boss bottom surface.
The cross section of the resistance material muscle is triangle.
The cross section of the bulge loop is semicircle.
The beneficial effects of the utility model are：
The utility model provides a kind of washer for lithium ion battery cover, and the step of base bottom is set as dual stage
Rank type structure, protects the small aluminium flake in step, and when battery seal can not only slow down the stress degree of small aluminium flake, and small aluminium flake
Even if there is a degree of deformation, effectively prevent small aluminium flake and come off by the extruding at slot rolling R angles and cause scrapping for battery,
It efficiently avoids battery R angles to contact with the direct of small aluminium flake, the positive and negative anodes short circuit of battery, user can be prevented well
Just, it is with obvious effects.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein：
1 matrix, 2 first boss
3 second boss, 4 dowel
5 resistance material muscle, 6 bulge loop.
Specific embodiment
With reference to the accompanying drawings of the specification and embodiment carries out in detail the utility model for the washer of lithium ion battery cover
It describes in detail bright：
As shown in Figure 1, a kind of washer for lithium ion battery cover, including matrix 1, the bottom surface of described matrix 1 is inside
The first boss 2 of the rectangular type of Formation cross-section, 2 inside of first boss are provided with the second boss 3 of the rectangular type in section, and first is convex
The vertical wall middle and upper part of platform 2 is connect at the top of the vertical wall of second boss 3 by dowel 4；It is formed in the middle part of 1 inner wall of described matrix
Resistance material muscle 5；2 top surface of first boss forms bulge loop 6.
1 top surface of described matrix is intilted inclined-plane.
The first boss 2 it is always open towards the outside of matrix 1.
The second boss 3 it is always open towards the inside of matrix 1.
The dowel 4 tilts upward setting from first boss 2 to second boss 3.
3 top surface of second boss is less than 2 top surface of first boss, higher than 2 bottom surface of first boss.
The cross section of the resistance material muscle 5 is triangle.
The cross section of the bulge loop 6 is semicircle.
The utility model provides a kind of washer for lithium ion battery cover, and the step of base bottom is set as dual stage
Rank type structure, when first boss is squeezed, due to thering is the muscle at certain angle of inclination and hollow presence, first boss just to have
Very big shrink space, second boss is with regard to stress very little, so as to protect the small aluminium flake in step.Can not only it subtract during battery seal
Delay small aluminium flake stress degree, even and if small aluminium flake have a degree of deformation, because matrix bottom first boss it is effective
It surrounds, effectively prevents small aluminium flake and come off by the extruding at slot rolling R angles and cause scrapping for battery, efficiently avoid battery R
Angle is directly contacted with small aluminium flake, can prevent the positive and negative anodes short circuit of battery well；The resistance material muscle of matrix inner wall, energetic,
Component height is limited, when mostly one combination material of dress any of which, resistance material muscle will be coated over below material, hence it is evident that seen
Less than resistance material muscle, it with the naked eye can intuitively check that block fills problem more；When otherwise material fills less, resistance material muscle will not be filled up
Away from the distance between bottom in washer, few the problem of filling is effectively prevented, improves block assembling quality；And combination material is pressed
Apparent pause and transition in rhythm or melody sense is had during into washer, and material thickness just fills up resistance material muscle away from distance between bottom in washer, firmly will
Combination material is stuck within sealing ring, no matter either vibrated, extruding and the stacking in level direction, material will not all take off
Fall, avoid well because vibrate, squeeze and the reasons such as oppositely positioned caused by material come off.It is easy to use, it is with obvious effects.
