In one embodiment, the battery case for new-energy automobile, including battery pack tray 10 and covering are provided in electricity
The lid (not shown) of 10 top end opening of pond group pallet.
In conjunction with shown in Fig. 1 to Fig. 3, battery pack tray 10 includes bottom plate 11, coaming plate 12 and support element 13.
Coaming plate 12 is protruded upward from the edge of bottom plate 11, and surrounds a groove for placing battery component with bottom plate 11.
Support element 13 is supported between bottom plate 11 and lid, including horizontally disposed first plate body 131 and is vertically arranged
The second plate body 132, the second plate body 132 is fixed on the top of the first plate body 131, and the first plate body 131 is formed between bottom plate 11.
In the technical solution, the second plate body 132 is supported in vertically between bottom plate 11 and lid, can be with when lid is installed
Play the role of a support limit to the lower surface of lid, in use, lid deformation can also be avoided to cause to electric in groove
The compressing of pond group.
In this case, the first plate body 131 and the second plate body 132 are preforming, can be integrally formed, when assembling, present bottom plate 11
In reserve the position of the first plate body 131, then the first plate body 131 is embedded in and realizes that the splicing between bottom plate 11 is fixed,
So that the first plate body 131 constitutes a part for bottom plate 11, to realize the whole installation of support element 13.
In a preferred embodiment, it is arranged for T shapes or L-shaped between the first plate body 131 and the second plate body 132.
In a preferred embodiment, the first plate body 131 and the second plate body 132 are integrally formed.
In a preferred embodiment, the first plate body 131 and the second plate body 132 use aluminum alloy material, in the first plate body 131
It is formed with the first cavity 1311 that both ends communicate.
Further, 1311 inner support of the first cavity has at least one the first supporting beam 1312 being vertically arranged.
In the technical solution, the first plate body 131 uses aluminum alloy material, while being arranged by cavity, and it is whole can to reduce its
Body weight.It is relatively high to the support strength requirement of vertical direction additionally, due to the first plate body 131, need the weight for carrying battery pack
Amount, therefore, this case can improve its support strength in vertical direction by the way that the first vertical supporting beam is arranged in the cavity,
It is unlikely to deform, service life is long.
In a preferred embodiment, the second cavity 1321 that both ends communicate is formed in the second plate body 132.
Further, the second cavity 1321 is supported by least one between two opposing sidewalls in the horizontal direction
Two supporting beams 1322.Non-perpendicular setting between second supporting beam 1322 and the side wall.
In the technical solution, the second plate body 132 uses aluminum alloy material, while being arranged by cavity, and it is whole can to reduce its
Body weight.It is relatively high to the support strength requirement of vertical direction additionally, due to the second plate body 132, it needs to carry lid and lid
External pressure, therefore, this case by being arranged the second supporting beam in this cavity, to improve its vertical direction support strength.
Further, it is contemplated that 132 vertical direction height of the second plate body is longer, if vertical direction is arranged in the cavity
Supporting beam, on the one hand, processing is inconvenient, and on the other hand, longer supporting beam support strength is bad, is extremely easy to happen bending and becomes
Shape.Therefore, multiple second supporting beams of this case are arranged in broken line, at an acute angle or blunt between the two side walls of the second plate body 132
The angle at angle, specifically, by the second supporting beam of multiple broken line shapes, whole cavity can be separated into multiple triangles or
Trapezoidal small cavity.
In addition, in order to ensure the uniformity of support, the second supporting beam includes two parts, and the supporting beam per part is parallel to be set
It sets, two-part supporting beam is staggered, and adjacent two-part supporting beam constitutes trapezoidal or triangular cavity isosceles two sides
Wall.
In a preferred embodiment, bottom plate 11 uses aluminum alloy material, including the multiple bottom board units 111 being spliced,
It is welded and fixed between adjacent bottom plates unit 111.
Further, each bottom board unit 111 is formed at least one cavity that both ends communicate along its length respectively
1111。
In the technical solution, 11 area of bottom plate of battery case is larger, is molded using aluminium alloy, and primary is difficult to obtain large area
Plate body while being arranged by cavity because this case is spliced using the welding of multiple bottom board units, ensureing its strength conditions
Under, its overall weight can also be reduced.
The battery case overall weight of this case is light, and support strength is high, and principle is：Be all made of on the whole aluminum alloy material at
Type, module units at least may include bottom plate 11, lid, coaming plate 12 and support element 13, in order to reduce its weight, each unit
Multiple cavities can be opened up in its plate body length direction, in order to ensure its intensity, can be set according to cavity size in each cavity
Set the supporting beam of different number.
In one embodiment, 10 assembling process of battery pack tray includes：First, by multiple bottom board units along certain direction battle array
Row splicing, while between the first plate body 131 of support element 13 is embedded in two neighboring bottom plate Unit 11, being allowed to constitute entire bottom
Then a part for plate 11 is welded, after the completion, all bottom board units and support element between the seam of adjacent bottom plates unit
13 structures are integral spare.Then, circuit bracket is located in the realization of 11 surface of bottom plate to be welded and fixed, and coaming plate 12 is located in
The edge of bottom plate 11, then by being welded and fixed between seam.
Further, it is further fixed on circuit bracket 20 on bottom plate 11, is formed between the second plate body 132 and is worn for circuit bracket
The recess 133 crossed.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
