Abstract

The present invention provides a kind of high intensity battery cases, including lower housing and upper cover plate, the lower housing is in square tubbiness, it is made of materials at two layers, the carbon fiber layer of stainless steel layer and outer layer including internal layer, carbon fiber layer is bonded in stainless steel layer outer surface by glue, the upper cover plate is in square plate shape, rectangular groove is provided on the inside of upper cover plate, the upper end of lower housing can be caught in groove, the side of the upper cover plate is provided with threaded hole, and lower housing upper end, which corresponds to, is provided with connecting hole, and upper cover plate is fixed after being buckled in above lower housing by bolt insertion threaded hole.The lower housing of this high intensity battery case has double layer material, since the rigidity and intensity of stainless steel plate are all relatively good, and the lighter in weight of carbon fibre material, so this high intensity battery case lower housing uses double layer material, not only meet intensity and toughness requirement, but also meet light-weight requirement.

Description

A kind of high intensity battery case
Technical field
The invention belongs to battery case technical fields, are related to a kind of high intensity battery case.
Background technology
Battery case (Battery Cases, Enclosures) or battery case, battery protection case, battery tank shell are used In the battery for accommodating and protecting electronic and the vehicle of hybrid power or the power battery on naval vessel, mobile phone or computer.In extreme case Under, for example, automobile collides, and power battery may burn in puncturing shock, explodes, and generates noxious material, electricity Pond breakage leads to safety accident.Battery case main problem currently used in the market is that mechanical strength is low, and tank capacity is small, weight Greatly, if using aluminum tank, although reducing weight, intensity is less desirable.For this reason, it may be necessary to which intensity is high, capacity is big, Light-weight battery case.New material, new process, newly-designed introducing, improve battery case intensity and safety (is not less than GB4208-2008 shell protections grade IP67), lightweight, while reducing cost.
High intensity, firm, impact resistance and shock, while light-weight, accurate size, at low cost, these requirements are generally applicable in In the battery case (electric vehicle, naval vessel) of power battery, laptop computer battery case etc..
The used material of battery case currently on the market is common iron, composite material or plastics, not using reinforcing work Skill is easily broken during high-speed impact.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of high intensity battery case,.
Object of the invention can be realized by the following technical scheme:A kind of high intensity battery case, including lower housing and upper Cover board, which is characterized in that the lower housing is in square tubbiness, is made of materials at two layers, including the stainless steel layer of internal layer and outer layer Carbon fiber layer, carbon fiber layer are bonded in stainless steel layer outer surface by glue, and the upper cover plate is in square plate shape, on the inside of upper cover plate It is provided with rectangular groove, the upper end of lower housing can be caught in groove, and the side of the upper cover plate is provided with threaded hole, lower housing upper end Corresponding to be provided with connecting hole, upper cover plate is fixed after being buckled in above lower housing by bolt insertion threaded hole.
Lower housing is two layers, and carbon fiber layer can protect stainless steel layer, in extraneous fierce knockout process, carbon fiber layer tool Have preferable tensile strength, can effectively prevent stainless steel layer by external force squeeze or hit and caused by distort.
Further, the thickness of the stainless steel layer is 1mm-1.5mm.
Further, the stainless steel layer is that high-strength alloy Steel material or ordinary carbon steel material pass through heat stamping and shaping.
Further, the thickness of the carbon fiber layer is 0.5mm-0.8mm, and carbon fiber layer is carbon cloth.
Further, it is distributed U-channel on the surface of the lower box.U-channel is set, the shock resistance of lower box is improved Property and intensity.
Further, the depth of the U-channel is 0.5mm.
Compared with prior art, the lower housing of this high intensity battery case has double layer material, since stainless steel plate is heavier, such as Fruit is all using stainless steel plate, then weight is big, if all using carbon fiber board, although lighter in weight, its intensity and Hardness does not reach requirement then, so this high intensity battery case lower housing uses double layer material, has not only met intensity and toughness requirement, but also symbol Close light-weight requirement.

In figure, 1, lower housing;11, stainless steel layer;12, carbon fiber layer;13, connecting hole;14, U-channel;2, upper cover plate; 21, groove;22, threaded hole.
Specific implementation mode
As shown in Figs 1-4, this high intensity battery case includes lower housing 1 and upper cover plate 2, and the lower housing 1 is in square tubbiness, by Materials at two layers is made, and includes the carbon fiber layer 12 of the stainless steel layer 11 of internal layer and outer layer, and carbon fiber layer 12 is bonded in by glue 11 outer surface of stainless steel layer, the upper cover plate 2 are in square plate shape, and rectangular groove 21 is provided in 2 inside of upper cover plate, lower housing 1 Upper end can be caught in groove 21, and the side of the upper cover plate 2 is provided with threaded hole 22, and 1 upper end of lower housing corresponds to and is provided with connecting hole 13, Upper cover plate 2 is buckled in behind 1 top of lower housing and is inserted into threaded hole 22 by bolt to fix.
Lower housing 1 is two layers, and carbon fiber layer 12 can protect stainless steel layer 11, in extraneous fierce knockout process, carbon fiber Tie up layer 12 have preferable tensile strength, can effectively prevent stainless steel layer 11 by external force squeeze or hit and caused by deform turn round It is bent.
The thickness of the stainless steel layer 11 is 1mm-1.5mm, and the stainless steel layer 11 is high-strength alloy Steel material or general Logical carbon steel material passes through heat stamping and shaping.
The thickness of the carbon fiber layer 12 is 0.5mm-0.8mm, and carbon fiber layer 12 is carbon cloth.
U-channel 14 is distributed on the surface of the lower box, the depth of the U-channel 14 is 0.5mm.U-shaped ditch is set Slot 14 improves the impact resistance and intensity of lower box.
