It is connected to hardboard region 3, there are four hardboard region 3 is set, setting is connected to the two sides in the second soft board region 22 two-by-two, and rubber shell 4 is wrapped up
In the outside in hardboard region 3.In an embodiment of the present invention, hardboard region 3 is pressed together with the second soft board region 22, rubber shell
4 are arranged and are fixedly connected on hardboard region 3, and cell device is located on hardboard region 3 in the present invention, soft board region 2 and hardboard
The material in region 3 includes copper foil, and the electric conductivity of copper foil is good, and resistance is low, can satisfy demand of the circuit to route, rubber shell 4
It is to protect the cell device on hardboard region 3 not damaged by external force.
Referring to Figure 1 and Figure 3, protrusion 5 be equipped with it is multiple, the first soft board region 21 setting protrusion 5 be the first protrusion 6, second
The protrusion 5 that soft board region 22 is arranged is the second protrusion 7.
In an embodiment of the present invention, the first protrusion 6 is located at the first soft board region 21, is not limited by 4 size of rubber shell,
Width can suitably be increased according to actual layout scenarios, the second protrusion 7 is located at the second soft board region 22 of the package of rubber shell 4, by glue
The limitation of 4 shape of shell can be arranged second according to the thickness and actual current demand of rubber shell 4 in the case where not influencing overall appearance
Protrusion 7 height, provided with multiple raised 5 further can locally increase battery protecting plate ontology 1 plate it is wide, increase electric current
The cabling area of copper foil can play the role of reducing battery protecting plate temperature rise.
Referring to Fig.1 with 3, there are two the first protrusion 6 is set, it is divided into raised 61 and lower convexity 62, upper raised 61 are located at first
The upside in soft board region 21, lower convexity 62 are located at the bottom side in the first soft board region 21.
In an embodiment of the present invention, upper raised 61 be the first soft board region 21 top plate, and plate face, which outwardly protrudes, to be formed,
Lower convexity 62 is the lower plywood in the first soft board region 21, what plate face was downwardly protrude to form, and multiple first protrusions 6 are arranged can be into one
The plate that step increases the first flexible board area 21 is wide, increases electric current cabling area, plays the role of the temperature rise for reducing the first soft board region 21.
Referring to Figure 1 and Figure 3, hardboard region 3 is equipped with the convex block 31 of the second protrusion 7 in the second soft board region 22 of matching.
In an embodiment of the present invention, hardboard region 3 faces out protrusion in location plate identical with the second soft board region 22
The convex block 31 of formation can locally increase the width in the second soft board region 22 and hardboard region 3 according to size of current and actual demand
Degree increases electric current cabling area, can play the role of the temperature rise for reducing the second soft board region 22 and hardboard region 3.
In an embodiment of the present invention, first one end of soft board region 21 far from hardboard region 3, bends upwardly to and hardboard
Region 3 is orthogonal, and in an alternative embodiment of the invention, first one end of soft board region 23 far from hardboard region 3 can also be with
Bent to other directions it is orthogonal with hardboard region 3, other bending directions include but is not limited to upward or downward.
Referring to FIG. 1, FIG. 2 and FIG. 4, rubber shell 4 is equipped with shrinkage pool 41, and convex block 31 and the second protrusion 7 are each provided in shrinkage pool 41.
In an embodiment of the present invention, valley portion represents 4 bottom of rubber shell and is worn by inner surface exterior surface is used in Fig. 2 dotted line
The shrinkage pool 41 of row, region is shrinkage pool 41 at Fig. 4 center choosing, and the shrinkage pool 41 that the bottom in rubber shell 4 is equipped with is according to battery protecting plate
Broadening width and be arranged, width in the horizontal direction and 41 horizontal direction of the shrinkage pool opening of the second protrusion 7 and convex block 31
Equivalent width, when the second soft board region 22 and hardboard region 3 are located in rubber shell 4, second protrusion 7 and convex block 31 be stuck in it is recessed
Setting in hole 41, rubber shell 4 itself has thickness, therefore the thickness of shrinkage pool 41 is equal to the thickness of rubber shell 4, and the thickness of rubber shell 4 can root
It is adjusted according to the broadening width in the vertical direction of the second protrusion 7 and convex block 31, in an alternative embodiment of the invention, shrinkage pool 41
Thickness than second protrusion 7 and convex block 31 vertical direction broadening width it is 0.1mm or more big, keep 4 base profile of rubber shell smooth,
So that same rubber shell 4, which packs size, can walk broader copper foil plus monnolithic case after rubber shell 4 without widening.
In above-mentioned rubber shell 4, rubber shell is wrapped with high tempreture tape on 4 outside.
In an embodiment of the present invention, high tempreture tape has the function of insulation and high temperature masking.
Referring to Fig.1, lower convexity 62 is L-type structure.
In an embodiment of the present invention, 62 side of lower convexity is the bottom side that the first soft board region 21 is arranged in L-type structure, under
Protrusion 62 is outwardly protruded by the bottom side in the first soft board region 21 to be formed, the bottom side of the shape of lower convexity 62 and the first soft board region 21
Shape matches.The area of lower convexity 62 is greater than upper raised 61 area, can preferably increase the width of the first flexible board area 21,
Increase electric current cabling area, play the role of reduce the first soft board region 21 temperature rise, in other embodiments of the present invention, under it is convex
The structure for playing 62 may be U type structure, specifically can be depending on the production shape of product.
Referring to Fig.1 and Fig. 4, the height of each upper protrusion 61, lower convexity 62 and the second protrusion 7 can be 0.1-0.4mm.
In an embodiment of the present invention, if upper raised 61, the lower convexity 7 and all broadening 0.4mm of convex block of the 62, second protrusion, if
The soft board region 2 of battery protecting plate is made of two the first soft board regions 21 and two the second soft board regions 22, the second flexible board area
22 two sides of domain respectively press two hardboard regions 3, then 21 broadening two upper raised 61 Hes of the first soft board region in battery protecting plate
Two lower convexity 62, broadening 1.6mm, 8 broadening two second protrusions 7 in soft or hard bond area and four convex blocks 31, broadening 2.4mm,
Battery protecting plate altogether can broadening 4mm, the width of copper foil will also increase 4mm, and through-current capability can be remarkably enhanced, and guarantee
In the case where the battery protecting plate plate tolerance is processed, increase copper foil height, is effectively reduced internal resistance and temperature rise, dramatically increases electricity
Gas performance, in an alternative embodiment of the invention, the number in soft board region 2 and hardboard region 3 can change according to practical layout situation,
In another embodiment of the present invention, the broadening width of protrusion 5 in soft board region 2 and hardboard region 3 can also change according to practical layout situation
Become.
The present invention compares previous technology, and beneficial effect is: increasing high current copper foil cabling area, reduces internal resistance, drop
Low-temperature-rise guarantees that battery protecting plate has the temperature environment of a proper operation；Improve that high current copper foil area before invention is narrow, hair
The big drawback of heat；Promote the electric property and reliability of product.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
