Specific embodiment
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
As shown in figs 1-9, the embodiment of the present application provides a kind of battery cap component, and which includes battery cap 10 and sealing
Nail 20, opens up liquid injection hole 100 on battery cap 10, electrolyte can pass through the inside that liquid injection hole 100 is injected into battery.Sealing nail 20
For sealing liquid injection hole 100, which may include spherical sealed nail 200, and the spherical sealed nail 200 can be matched somebody with somebody with the sealing of liquid injection hole 100
Close.Spherical sealed nail 200 herein has spherical outer surface.
Due to the construction featuress of spherical sealed nail 200 so that when spherical sealed nail 200 is assembled in liquid injection hole, not only may be used
To provide certain guide effect, also there is no directivity, therefore when the spherical sealed nail 200 is installed, when avoiding the need for spending
Between recognize its installation direction.So, the battery cap component is capable of the leakage efficiency of lift-off seal nail 20.In addition, spherical sealed
Nail 200 it is relatively simple for structure, be easily worked, processing cost is than relatively low.
In order to improve the sealing property at liquid injection hole 100, sealing nail 20 may also include lid sealing nail 201, and this lid is close
Envelope nail 201 can be coordinated with the sealing of liquid injection hole 100, and this lid sealing nail 201 is located at the top of spherical sealed nail 200.Herein
Top be defined according to state shown in figure.After being arranged such, it is possible to by spherical sealed nail 200 and lid sealing nail
201 are coordinated with liquid injection hole 100 simultaneously so that the sealing at liquid injection hole 100 is higher.
During production battery, in order to ensure that the sealing property at liquid injection hole 100 can meet requirement, it usually needs right
Sealing at liquid injection hole 100 is tested.When sealing nail 20 includes spherical sealed nail 200 and lid sealing nail 201, so that it may
To detect the sealing between spherical sealed nail 200 and lid sealing nail 201 and liquid injection hole 100 respectively.For example, can first by ball
Shape sealing nail 200 is put in liquid injection hole 100, then detects whether the sealing between spherical sealed nail 200 and liquid injection hole 100 reaches
To requiring；Then lid sealing nail 201 is put in liquid injection hole 100, then detect lid sealing nail 201 and liquid injection hole 100 it
Between sealing whether reach requirement.
However, when adopting aforesaid way, when the sealing between lid sealing nail 201 and liquid injection hole 100 is detected, due to
Spherical sealed nail 200 is coordinated with the sealing of liquid injection hole 100, therefore can not truly reflect lid sealing nail under this state
Sealing between 201 and liquid injection hole 100.Specifically, when lid sealing nail 201 has poor sealing (example with liquid injection hole 100
Such as, using the defect that often there is failure welding, rosin joint during welded seal) when, there is ball due to sealing in assembling process
Shape seals the pre-sealed of nail 200, therefore cannot detect the sealing between lid sealing nail 201 and liquid injection hole 100 exactly.This
Outward, as spherical sealed nail 200 often adopts continuously connected fastener, which is easily aging after long-term use so that itself departs from and liquid injection hole
100 sealing state, the poor sealing problem between now lid sealing nail 201 and liquid injection hole 100 will come out, and cause
Sealing between whole sealing nail 20 and liquid injection hole 100 is not readily available guarantee.
In order to solve the above problems, as viewed in figures 5-8, above-mentioned lid sealing nail 201 may include rivet nut 201a and fixation
Raised 201b in rivet nut 201a.This raised 201b is located between rivet nut 201a and spherical sealed nail 200, and which is relative to nail
Body 201a can be contacted with spherical sealed nail 200 to the direction protrusion near spherical sealed nail 200, and projection 201b.

Lid sealing nail 201 is loaded in liquid injection hole 100.Now, the raised 201b of lid sealing nail 201 can be with spherical sealed nail 200
Contact, so as to form relatively closed space between the hole wall of liquid injection hole 100, spherical sealed nail 200 and lid sealing nail 201.
When lid sealing nail 201 is welded on battery cap 10, the temperature of the spatial peripheral increases, and the gas in which can be with temperature
Rising and expand, and then produce instantaneous pressure, spherical sealed nail 200 will be subject to the active forces that gas applies, and to battery
Inside movement, finally depart from liquid injection hole 100, this process may be referred to Fig. 8 and Fig. 9.In this case, then covered
When the sealing propertytest between 201 and liquid injection hole 100 is followed closely in shape sealing, make as spherical sealed nail 200 cannot play sealing
With the sealing that lid sealing nail 201 is formed at gas communication, therefore liquid injection hole 100 with inside battery only relies on lid sealing nail
201, so now being detected the sealing feelings that just can reflect truly, exactly between lid sealing nail 201 and liquid injection hole 100
Condition, it is possible to obtain more accurate testing result.
Generally, the surface on above-mentioned raised 201b for 200 phase separations are followed closely with spherical sealed can adopt plane or song
Face, but after being arranged to curved surface, the active area between raised 201b and spherical sealed nail 200 can be smaller, therefore the application
Surface on embodiment preferably projection 201b for contacting with spherical sealed nail 200 is plane.In addition, this kind of structure can also
Simplify the processing technique of lid sealing nail 201.
Usually, in order to reach preferable sealing, spherical sealed nail 200 can adopt elastic construction, by spherical sealed
The elastic deformation produced after following closely 200 stress reaches object defined above, however, when spherical sealed nail 200 deforms, extending thereon
Material lid sealing nail will be caused 201 low with the assembly precision of liquid injection hole 100.In view of this, can carry out as divided into
Put：In the projection obtained along the axial direction of liquid injection hole 100, have between the inwall at the edge and liquid injection hole 100 of raised 201b and keep away
Allow gap.Alternatively, aforementioned raised 201b could be arranged to cylindrical protrusions, and liquid injection hole 100 could be arranged to cylindrical hole, this
The diameter of cylindrical protrusions forms aforesaid avoidance gap with this less than the diameter of liquid injection hole 100.Now, once spherical sealed
Nail 200 deforms, and the material for extending thereon can enter above-mentioned avoidance gap, ensures that lid sealing nail 201 has enough with this
Installing space.
Further, as shown in figure 9, in order to be more reliably prevented from the deformation of spherical sealed nail 200 to lid sealing nail 201
Installation produce harmful effect, can arrange in rivet nut 201a at the position of projection 201b and open up depressed part E, depressed part E to
It is connected with aforesaid avoidance gap away from the direction depression of spherical sealed nail 200, and depressed part E.That is, when spherical
When sealing nail 200 deforms, the material for extending thereon can be entered in depressed part E herein by above-mentioned avoidance gap, because
The quantity of material that this depressed part E can be accommodated is more.
In specific embodiment, above-mentioned depressed part E can be locally provided in rivet nut 201a, but in order to obtain bigger keeping away
Allow space, depressed part E can be set to annular recess, the circular direction of this annular recess and the circumference of liquid injection hole 100
