Embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to embodiment
And referring to the drawings, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
The structural assembly 100 of accompanying drawing 2- accompanying drawings 5, lithium battery group provided by the utility model and protection board is referred to, is wrapped
Lithium battery group 10 is included, the support 20 in lithium battery group 10, and the protection board 30 being assemblied on support 20.Wherein, it is described
Multiple nickel sheet 11 are electrically connected with lithium battery group 10, and are engaged with protection board 30, so as to follow-up plating tin welding, and finally
Realize that lithium battery group 10 is powered to the circuit board that there is institute's soldering on protection board 30.
In the present embodiment, it is directly to be assembled between the nickel sheet 11 on the protection board 30 and lithium battery group 10, and
Manually nickel sheet need not be pressed on protection board 30, so be to realize its automation welded when producing and preparing.
Specifically, the multiple nickel sheet 11 being electrically connected in lithium battery group 10 are stretched in one end part away from lithium battery group 10
Enter to the opening position between support 20 and protection board 30, then stretched out again from protection board 30.Correspondingly, on the protection board 30
It is corresponding to offer multiple pilot holes 31, and the nickel sheet 11 is specifically outwardly directed from the pilot hole 31 on protection board 30.
From the foregoing, it will be observed that the nickel sheet 11 come out to from lithium battery group 10 from pilot hole 31 on protection board 30 out its need
Passing through could realize by way of bending, therefore, being provided with two kinks in the nickel sheet 11, be respectively defined as the first kink
111 and second kink 112, wherein first kink is specifically to stretch to support 20 and protection board 30 from lithium battery group 10
Between opening position, second kink 112 from protection board 30 the part of pilot hole 31 stretch out.In the present embodiment, institute
The bending angle for stating the first kink 111 and the second kink 112 is 90 °.
In the present embodiment, the protection board 30 only sets a plating on a side end face of the protection board 30 away from support 20
Tin layers 32, and can use it to be welded and fixed nickel sheet and protection board, that is, protection board 30 is specifically used for and nickel in the present embodiment
The tin coating 32 that piece 11 is welded and fixed is positioned only on the outer face of protection board 30, and it is during actual production, phase
The step for can setting up drilling more specific than prior art, obtained after the tin coating in the middle level of protection board 30 is removed.Also
The tin coating 32 for being specifically used for being welded and fixed with nickel sheet 11 i.e. on protection board 30 is provided in the outer layer of protection board 30, so
When nickel sheet 11 and protection board 30 are welded and fixed with welding gun, the welding between the protection board 30 and nickel sheet 11 of the present embodiment
Node only on the outer layer of protection board 30, is so welded and fixed compared to existing protection board with nickel sheet, light using flatiron
Pine separates nickel sheet with protection board, and then has been easy to dismounting.Further, tin coating 32 and pilot hole 31 on the protection board 30
Between leave 0.1mm gap.This clearance distance avoids causes that tin does not connect or heap tin is too many because distance is too big,
It will not cause to be not easily disconnected from because too small, this is the optimal spacing obtained under limited number of time experiment.
In addition, the protection board 30 of the present embodiment is provided with clear area (not shown) in the periphery of each of which pilot hole 31,
And the tin coating 32 does not cover to the clear area on protection board 30.That is, in the clear area of the protection board 30 and to set
It is equipped with tin coating 32 to cover, so accordingly, when protection board 30 is welded and fixed with nickel sheet 11, does not have weldering in clear area
Binding place, so further it is easy to be separated nickel sheet 11 and protection board 30.Pilot hole 31 on the protection board 30
Bore is more than the external diameter for the nickel sheet 11 for being contained in the pilot hole 31, is preferably slightly larger than.That is, the present embodiment nickel sheet 11 by way of
Pilot hole 31 on protection board 30 and it is protruding when, its nickel sheet 11 is not contacted directly with pilot hole 31 on protection board 30
's.So on the one hand, it has been easy to the assembling between nickel sheet 11 in the entirety of protection board 30 and support 20 and lithium battery group 10；Separately
On the one hand, when the one of damage of the battery core or protection board 30 of lithium battery group 10, using flatiron easily by nickel sheet with protecting
Backplate separates, and then can utilize the gap between nickel sheet 11 and pilot hole 31 again, be siphoned away with tin small of the stock tin, thus easily
Both are separated, it is easy to disassemble.
It is appreciated that when protection board 30 is specifically assembled on support 20, for the ease of assembling, the present embodiment can prop up
Multiple spacing cams 21 are set on frame 20, it is spacing to be carried out to the protection board 30 being assemblied on the support 20.In the present embodiment,
Spacing cam 21 on the support 20 is concentrated located at the side of support 20.Moreover, for the ease of the lithium battery group that will be assembled
10th, support 20 carries out follow-up soldering with protection board 30, the present embodiment, specifically uses screw 101 by protection board 30 and support 20
It is fixedly connected and plays.
To sum up, the structural assembly of lithium battery group of the present utility model and protection board, nickel sheet in lithium battery group and protection are passed through
Rational structure setting between pilot hole on plate so that when producing preparation, protection board can be directly securely fitted in lithium battery
On support in group, and nickel sheet operation need not be manually pressed, so be achieved that the operation of automatic welding；And pass through protection
The Rational structure of tin coating is set on plate so that when protection board and nickel sheet are attached into fixed with welding gun, both is only outside
Layer is welded and fixed, and so when the one of damage of the battery core or protection board of lithium battery group, easily will using flatiron
Nickel sheet separates with protection board, and then has been easy to dismounting.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model all should be included in
Within the scope of protection.
