Wherein, the height of multiple aluminium section bars is identical, and multiple aluminium section bars can be same aluminium section bar, can so cause side
Enclose 20 height it is identical, so as to improve the overall leveling of battery container 100.
The arrangement form of hanger 30 once is described in conjunction with gusset 20 below.
A part for multiple hangers 30 is welded and fixed with corresponding aluminium section bar, and another part of multiple hangers 30 with it is right
The aluminium section bar answered is formed in one part.That is, according to actual production design conditions, a part can be with individually designed, then
On aluminium section bar corresponding to being weldingly fixed on again, another part hanger 30 can be using integral extrusion forming by the way of and gusset 20
Aluminium section bar is integrally formed.Thus, by rationally designing the fixed form of each hanger 30, can aspect hanger 30 can be caused to exist
It is fixed reliable on gusset 20, the assembly difficulty between hanger 30 and gusset 20 on the other hand can be reduced, battery case can be shortened
The manufacturing cycle of body 100.
As shown in figure 1, the horizontal aluminium section bar 20a positioned at front is corresponding with two hangers 30 spaced apart, and before being located at
The horizontal aluminium section bar 20a of side is welded and fixed with two hangers being spaced apart 30.Hanger 30 positioned at front is general highly larger, this
Sample can pass through welding manner and gusset 20 in order to the matching of battery container 100 and the bottom space of vehicle, hanger 30 so
Fixation is relatively reliable.
As shown in figure 1, the horizontal aluminium section bar 20a being located behind is corresponding with two hangers 30 spaced apart, and after being located at
Horizontal aluminium section bar 20a and two hangers being spaced apart 30 of side are formed in one part.Further, longitudinal aluminium section bar 20b is four, side
The every side for enclosing 20 is provided with two longitudinal aluminium section bar 20b of time interval, the longitudinal aluminium section bar 20b being located behind and four intervals
The correspondence of hanger 30 opened, and the longitudinal aluminium section bar 20b being located behind and four hangers being spaced apart 30 are formed in one part.By
This, without the horizontal aluminium section bar 20a to be located behind and longitudinal aluminium section bar 20b matching hangers 30, so as to reduce battery case
The manufacture difficulty of body 100.
Further, as shown in figure 1, being welded and fixed positioned at longitudinal the aluminium section bar 20b and window corner aluminum profile 20c in front junction
There is a hanger 30.The volume of the hanger 30 is generally large, so as to improve battery container 100 and the bottom space of vehicle
Fixed reliability.
Alternatively, multiple hangers 30 are symmetrical on the axis of gusset 20.Thus, multiple uniform forces of hanger 30,
So as to improve fixation reliability of the battery container 100 in the bottom space of vehicle.
Specifically, multiple hangers 30 are aluminium section bar, and as shown in figure 8, the height of multiple hangers 30 is more than multiple aluminium
The height of section bar.The hanger 30 being arranged such can be fixedly connected in order to it with the bottom space of vehicle, can reduce gusset 20
Influence to assembling.
Wherein, for multiple hangers 30 formed with hollow structure 2 34, hollow structure 2 34 can be used for the weight for reducing hanger 30
Amount.
Wherein, the hollow structure 2 34 of hanger 30 can be rectangle, and the volume of rectangle is larger, so as to preferably remove
The weight of hanger 30, it can make it that hanger 30 is in light weight.
According to a specific embodiment of the present utility model, as shown in Fig. 6, Fig. 7 and Fig. 9, hanger 30 includes：Vertical limb two
31 and horizontal limb 2 32, vertical limb 2 31 is connected to the side of horizontal limb 2 32, and the hollow structure 2 34 of vertical limb 2 31
It is different from the placement direction of the hollow structure 2 34 in horizontal limb 2 32.Vertical limb 2 31 is vertically extending, horizontal limb two
32 is horizontally extending, as shown in fig. 7, the hollow structure 2 34 in vertical limb 2 31 is vertically placed, in horizontal limb 2 32
Hollow structure 2 34 is laterally disposed.In this way, hollow structure 2 34 can be allowd to ensure vertical limb 2 31 and horizontal limb 2 32
Structural strength while, effectively reduce hanger 30 weight.
Round-corner transition is used between the side wall of limb 2 31 and the roof of horizontal limb 2 32 vertically.Thus, the vertical He of limb 2 31
Transition is connected between horizontal limb 2 32 naturally, reliable so as to improve the connection between vertical limb 2 31 and horizontal limb 2 32
Property.
Alternatively, the height of vertical limb 2 31 can be h1, wherein, 50mm≤h1≤80mm.Meet above-mentioned relation formula
The vertical height of limb 2 31 is suitable, thereby may be ensured that the connective stability between battery container 100 and the bottom space of vehicle.
Specifically, as shown in fig. 6, there is the inner surface of horizontal limb 2 32 first gusset stationary plane 35 and the second gusset to fix
Face 36, the angle between the first gusset stationary plane 35 and the second gusset stationary plane 36 is obtuse angle.Thus, on horizontal limb 2 32
One gusset stationary plane 35 and the second gusset stationary plane 36 can be fixed on longitudinal the aluminium section bar 20b and window corner aluminum profile of gusset 20
Between 20c, it can so make it that the location arrangements of hanger 30 are suitable, and can make it that the structure of hanger 30 is reliable.
Alternatively, as shown in fig. 6, the projection of vertical limb 2 31 and horizontal limb 2 32 can be trapezoidal.This projection refers to
Projection in the horizontal plane.Such hanger 30 is reasonable in design, can be effectively matched gusset 20, thereby may be ensured that gusset 20
Cooperation reliability between hanger 30.
Further, as shown in Figure 6 and Figure 7, horizontal limb 2 32 also has the lower extension for extending laterally and being located at lower surface
Plate 33.Lower extension board 33 can strengthen the fixation reliability between hanger 30 and gusset 20.
