Embodiment approach

[0066] According to yet another specific embodiment of the present invention, the plate body 8 includes a plurality of recesses 7 that are recessed downwards, and the recesses 7 are configured to be able to bear against the top wall of the beam 1 to be assembled with the beam 1 , the structure is simple, which is conducive to improving the assembly strength between the shell and the beam, and optimizing the protection effect of the power battery pack. Further, the recess 7 can be provided with a plurality of installation holes at intervals, and the top wall of the beam 1 includes a plurality of installation points corresponding to the plurality of installation holes, so as to be assembled to the installation points of the beam 1 by fasteners such as bolts. , which improves the assembly strength between the upper shell and the beam.

[0067] According to another specific embodiment of the present invention, such as Figure 7 As shown, the side beam includes a transverse beam 1...

Abstract

The invention relates to the technical field of vehicles, in particular to a power battery pack and a vehicle. The power battery pack comprises an outer shell with a cavity and a module contained in the cavity, the outer shell comprises an upper shell body and a lower shell body with an upward opening, the upper shell body comprises a plate body and an outer edge, and the outer edge extends downwards from the periphery of the plate body and inclines outwards. The plate body covers the opening of the lower shell through the outer edge, the lower shell comprises a boundary beam and a mounting box mounted on the boundary beam, in the height direction, the top wall of the boundary beam is flush with the top wall of the mounting box to jointly form the opening of the lower shell, and the top wall of the boundary beam is arranged adjacent to the top wall of the module. According to the power battery pack, through the structure, the top wall of the boundary beam is lifted, the required heightof the outer edge of the upper shell is reduced accordingly, the adverse effect that the cross sectional area of the outer edge is gradually reduced along with the increase of the height is weakened,and the space utilization rate of the cavity is increased.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power battery pack and a vehicle. Background technique [0002] As the country vigorously promotes the field of new energy, electric vehicles have become the mainstream trend in the future. Among them, the power battery pack, as the core power supply component of the vehicle, determines key indicators such as the driving range, cost, service life, safety, and maintainability of the vehicle. [0003] At present, the power battery pack includes a casing and a module, the casing has a chamber, and the module is packaged in the chamber; wherein, the casing includes a lower casing and an upper casing, and the lower casing is usually set so that the height of the side beam is significantly lower than The height of the installation box installed on the side beam makes the top wall of the lower shell uneven. In order to match the shape of the lower shell, the upper shell also needs t...
