Paper will assist installation set 63 to be pasted on reinforcing beam 61 and bottom plate 2 simultaneously, and it is soft that auxiliary installation set 62 can be enable to be completely covered by
Property item 62.During installing battery 1, battery 1 can gradually be placed in bottom plate 2 along the surface of auxiliary installation set 63
On, it is directly contacted with flexible strip 62 to avoid because of battery 1, frictional force is larger and increases installation difficulty；Meanwhile assisting installation set 63
Certain limit and protective effect can also be played, to flexible strip 62 to extend the service life of flexible strip 62.
Further, multiple batteries 1 can form a battery pack, and each battery pack can be correspondingly arranged at least one
Positive stop strip 6, in order to make each battery in battery pack that can limit cooperation, on mentioned length direction, battery pack with positive stop strip 6
Projection can corresponding setting positive stop strip 6 projection overlapping.
Specifically, multiple batteries 1 can be divided into multiple battery packs by equivalent, multiple battery packs can be respectively corresponded and are provided with
Multiple positive stop strips 6, such as in the longitudinal direction, a positive stop strip 6 has can be set in the opposite sides of a battery pack, this can be with
Positive stop strip 6 is further increased to the limit effect of battery 1.In a thickness direction, the length of positive stop strip 6 can be greater than or equal to single
The length of a battery pack, the surface of this battery 1 that positive stop strip 6 can be made to be completely covered in the longitudinal direction near proximal panel 3, with
Guarantee that each battery 1 does not appear in the displacement that this side up.
Further, as shown in figure 4, reinforcing beam 61 may include interconnecting piece 611 and limiting section 612, limiting section 612 can be with
It is connect by interconnecting piece 611 with bottom plate 2；Connecting hole 612a can be set on limiting section 612, press strip 4 can pass through the company of passing through
The connector for meeting hole 612a is connect with limiting section 612.
Specifically, limiting section 612 can be square structure, two sides can be distinguished on the limiting section 612 of square structure
For contacting with battery 1, and the structures such as insulating layer, flexible layer can also be covered on both of the aforesaid surface, further to protect
Battery 1.It can be bored on limiting section 612 and process multiple connecting hole 612a, it can also be directly on the inner wall of connecting hole 612a
Vehicle Processing goes out internal screw thread, allows to directly be connected through a screw thread the screw-internal thread fit of part Yu connecting hole 612a, and connection trim strip 4
With limiting section 612.Optionally, bushing 40 is also provided between press strip 4 and positive stop strip 6, bushing 40 can be set in connection
On part, bushing 40 can prevent occurring the case where excessively locking between press strip 4 and positive stop strip 6.Interconnecting piece 611 can be long for plate
Structure, the quantity of interconnecting piece 611 can for one, it is two or more.
Further, positive stop strip 6 may include a limiting section 612 and two interconnecting pieces 611, and two interconnecting pieces 611 can
To be connected to the two sides of limiting section 612, and two interconnecting pieces 611 can be recessed to close to mutual direction.
Specifically, along its length, two interconnecting pieces 611 can be connected to the two sides of 612 bottom surface of limiting section, connection
Part-structure in portion 611 can be recessed to close to mutual direction, and to form accommodation space, which can accommodate soft
At least part of property item 62.In sticking flexible item 62, the interconnecting piece 611 with aforementioned accommodation space can play pre-determined bit
Effect；Meanwhile after being squeezed and compressing in flexible strip 62, accommodation space can accommodate compressed flexible strip 62, so that
The stress of battery 1 in the height direction is more evenly.
More specifically, in order to prevent because 611 indent of interconnecting piece is likely to occur the case where stress is concentrated, interconnecting piece 611 can be with
It, in the height direction, can during changeover portion 611b extends to close bottom plate 2 including being bonded section 611a and changeover portion 611b
With gradually to close to mutual direction transition, then, fitting section 611a can be connect by changeover portion 611b with limiting section 612,
Flexible strip 62 can fit on fitting section 611a, and being bonded between section 611a and auxiliary installation set 63 has accommodation space, the appearance
At least part of flexible strip 62 can be accommodated by receiving space.Fitting section 611a and changeover portion 611b can be integrally formed, can also be with
Fission molding, then connect together by welding.
In order to improve in short transverse and length direction, to the limit effect of battery 1, a kind of preferred specific embodiment
It is that press strip 4 and positive stop strip 6 can be set multiple, and the two sides for any battery 1 arranged in the longitudinal direction can be set
Press strip 4 and positive stop strip 6, and multiple press strips 4 and multiple positive stop strips 6 can be arranged in a one-to-one correspondence, the limit to battery 1 can be improved in this
Position effect, to further increase the safety of entire battery pack.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair
