When four supporting beams 5, fastener 7 can be also cross the mounting hole 66 on beam element 6, the peace on 30 side plate of lower layer's battery modules
The mounting hole 66 (the corresponding design of three's hole location) in hole 66 and bracket supporting beam 20 is filled, such setting can make beam element 6, battery
The mounting hole 66 being correspondingly arranged on 30 side plate of mould group and bracket supporting beam 20 shares the same bolt, so as to reduce bolt
Quantity is set, and then can reduce the weight of the double-deck module bracket 10, the production cost of the double-deck module bracket 10 can also be reduced.
Wherein, the mounting hole 66 on 30 side plate of upper layer battery modules can be corresponded with the mounting hole 66 on beam element 6
Setting can be by bolt also cross the mounting hole 66 and upper layer battery on beam element 6 when assembling upper layer battery modules 30
Mounting hole 66 on 30 side plate of mould group is assembled together upper layer battery modules 30 and the double-deck module bracket 10, and setting can in this way
Facilitate installation bolt, it is possible to reduce worker operation working hour, also, avoid the influence that battery modules 30 are installed in welding.
In some embodiments of the invention, it can have thread bush in mounting hole 66, also can be set in pilot hole 65
There is thread bush, such setting can make bolt preferably be assembled together with thread bush, bolt looseness can be prevented, so as to
Guarantee the reliability of installation.
In some embodiments of the invention, the upper surface and/or upper surface of support plate 1 can be set thermal insulation layer or
Heat conductive pad.It should be noted that thermal insulation layer or heat conductive pad only can be provided in the upper surface of support plate 1, can also only exist
The lower surface of support plate 1 is provided with thermal insulation layer or heat conductive pad, can also be arranged simultaneously in the upper and lower surfaces of support plate 1
There are thermal insulation layer or heat conductive pad.Wherein it is possible to according to actual needs, upper surface, the lower surface of support plate 1 paste thermal insulation layer or
Person's heat conductive pad, thermal insulation layer have heat-blocking action, and setting in this way can prevent the heat transfer of lower layer's battery modules 30 to upper layer electricity
Chi Mo group 30 is also possible to prevent the heat transfer of upper layer battery modules 30 to lower layer's battery modules 30, so as to prevent battery
Thermal runaway occurs for mould group 30.Also, heat conductive pad has thermally conductive function effect, and the heat transfer that can make battery modules 30 is arranged such
To the double-deck module bracket 10, heat can be made to distribute from the double-deck module bracket 10.
In some embodiments of the invention, support plate 1 can be set to aluminium sheet, and support plate 1 can have lightening hole,
In, lightening hole has loss of weight effect, and setting in this way can be further reduced the weight of the double-deck module bracket 10, can be further real
The light-weight design of existing bilayer module bracket 10, also, support plate 1 can be set to plate, may be set to be profile.
Wherein, 10 changeability of the double-deck module bracket of the application is strong, can be according to design strength demand, double-mold group branch
The structure type of the supporting beam of frame 10, installation point position, support plate 1 form can be carried out change meet demand.Also,
In the case that battery pack height allows, molding cavate profile is can be set to increase intensity in support plate 1.
Battery pack according to an embodiment of the present invention, the double-deck module bracket 10 including above-described embodiment, the double-deck module bracket
10 settings are mounted in battery pack, which can eliminate the need for elbow tool and install the double-deck module bracket 10
