Specific implementation mode
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention Rather than it limits the scope of the invention.In the following examples, the experimental methods for specific conditions are not specified, usually according to conventional strip Part or according to the normal condition proposed by manufacturer.
Unless otherwise defined, all professional and scientific terms used in text and meaning known to one skilled in the art Justice is identical.In addition, any method and material similar or impartial to described content can be applied to the method for the present invention.Wen Zhong The preferred implement methods and materials are for illustrative purposes only.
Battery pack bottom tray
As shown in Figure 1, the battery pack bottom tray of the present invention, is formed by 1 welding of extruded aluminium section, inside has cavity.
Aluminium section bar is exactly that aluminium bar is hot-melted and extruded, to obtain the aluminum material of different cross section shape.Extruding be proximate matter at The means of shape, first according to product forms section design, produce mold, using extruder by the round casting rod heated from mold Extrusion molding.The extruded aluminium section of the present invention, inside are hollow structure.
In another preferred example, it is welded again with agitating friction after first carrying out extruded aluminium section splicing using automatic jig, Obtain the battery pack bottom tray.
In a preferred embodiment, the weight of the battery pack bottom tray is 8-10kg.
In a preferred embodiment, the volume of the battery pack bottom tray is 0.001-0.005m3。
In a preferred embodiment, the area of the battery pack bottom tray is 2.2-2.8m2。
In a preferred embodiment, the aluminium section bar is internally provided with reinforcing rib.
In the present invention, the arrangement of reinforcing rib is related with required bottom bracket intensity, can be according to required bottom bracket intensity It needs to use means, as CAE simulations are designed.
The bottom bracket of the present invention carries out welding using extruded aluminum and forms, aluminium two-dimensional end surface has been concentrated to be molded advantage, It can effectively prevent the heat of vehicle halted state from transmitting using hollow material, while the reinforcing rib width of hollow material can also be utilized Adjustment, carry out the design of pilot hole, the overall processing after welding is assembled good has a high dimensional consistency, due to using hollow type Material designs, and by the structural mechanics of end face designing material and the inherent mechanical structure of material, the bottom bracket of aluminium section bar only has 8-10KG or so.Be approximately the half of the weight of steel pallet, cost is but consistent with rigid cost, if considering recycling, overall cost with Steel is compared and wants low.
As shown in Fig. 2, battery pack bottom tray is also configured with cooled plate 2.
In a preferred embodiment, inlet and outlet, the cooled plate inner hollow, water are set in cooled plate 2 2 inside of cold plate has fluid channel 3.
In another preferred example, 2 inside of cooled plate is equipped with water, for cooling the battery.
