Based on the above overall description, specifically, firstly, in view of the arrangement of the front floor panel 102, similar to most of the existing vehicle types that adopt the battery pack and the vehicle body to integrate, the battery pack frame structure of the present embodiment is located in the middle of the whole vehicle, and the battery pack frame structure serves as both the housing of the battery pack and the chassis structure in the middle of the whole vehicle, so as to realize the integrated design of the battery pack housing and the vehicle body structure. In addition, a bottom tray 3 is also generally attached to the bottom of the battery pack frame structure, similar to the design in the existing vehicle model, for closing the battery module mounting space 10 and protecting the internal battery module 20 and related electrical components.

In the present embodiment, as a preferred embodiment, as shown in fig. 4 and 5, the upper frame 101 is provided with an upper cross member 104 disposed along the left-right direction of the vehicle body on the inner side, and the lower frame 201 is also provided with a lower cross member 202 disposed along the left-right direction of the vehicle body on the inner side. The upper cross member 104 and the lower cross member 202 are each a plurality of ones arranged at intervals in the vehicle body front-rear direction, and the present embodiment is further provided with a center tunnel 103 arranged in the vehicle body front-rear direction inside the upper bezel 101.

In addition, in the present embodiment, the upper cross members 104 and the lower cross members 202 are arranged to provide a force transmission channel in the left-right direction of the vehicle body, so that the capability of the entire vehicle to cope with the pillar impact and the side impact can be improved. The arrangement of the middle channel 103 can provide a force transmission channel in the front-back direction of the vehicle body, so that the capacity of the whole vehicle for coping with direct collision can be improved.

As also shown in fig. 4, as a preferred embodiment, the upper frame 101 of the present embodiment has upper side members 1011 which are disposed on the left and right sides, respectively, and an upper front side member 1012 which is connected between the front ends of the upper side members 1011 on both sides, and an upper rear side member 1013 which is connected between the rear ends of the upper side members 1011 on both sides. Each upper cross member 104 is connected between the side upper beams 1011 and the center tunnel 103 is connected between the upper front beam 1012 and the upper rear beam 1013.

Similarly to the structure of the upper frame 101, the lower frame 201 of the present embodiment also has lower side beams 2011 respectively provided on the left and right sides, a lower front beam 2012 connected between the front ends of the lower side beams 2011 on the two sides, and a lower rear beam 2013 connected between the rear ends of the lower side beams 2011 on the two sides, and each lower cross member 202 is connected between the lower side beams 2011 on the two sides.

On the basis of the above structure of the upper frame 101 and the lower frame 201, the present embodiment preferably causes both the upper front side member 1012 and the lower front side member 2012 to arch forward in the vehicle body longitudinal direction, and causes both the upper rear side member 1013 and the lower rear side member 2013 to arch rearward in the vehicle body longitudinal direction. In this way, the upper front edge beam 1012 and the lower front edge beam 2012 are arched forwards, and the upper rear edge beam 1013 and the lower rear edge beam 2013 are arched backwards, so that the structural strength of the upper frame and the lower frame can be better improved by utilizing the characteristic of high arched structural strength, and the collision force at the upper front edge beam 1012 and the lower front edge beam 2012, and at the upper rear edge beam 1013 and the lower rear edge beam 2013 can be transmitted to the upper side beam 1011 and the lower side beam 2011 at two sides, thereby improving the collision safety of the whole battery pack frame structure.

The first upper cross member 1041 and the third upper cross member 1043 mainly perform lateral (i.e., left-right direction of the vehicle body) reinforcement and transfer of a collision force between a pillar and a side collision. The two middle second upper cross beams 1042 not only can play a role in transversely reinforcing and transferring collision force, but also can be used as front seat mounting beams for mounting a front seat in a vehicle body. In specific implementation, the front seats are mounted on the two second upper cross beams 1042 by adopting the conventional bolt connection mode.

Based on the arrangement of the center tunnel 103, as a preferred embodiment, the upper front frame 1012 and the upper rear frame 1013 in the present embodiment are divided into two parts respectively disposed on the left and right sides of the center tunnel 103 by the center tunnel 103, and at the same time, the part of the upper cross member 104 is divided into two parts respectively disposed on the left and right sides of the center tunnel 103 by the center tunnel 103. At this time, the transmission of the collision force between the respective parts of the upper frame 1 can be improved by the better engagement between the upper front frame 1012, the upper rear frame 1013, and the upper cross member 104, which contributes to the formation of the force transmission network in the upper frame 1.

In this embodiment, as mentioned above, a reinforcing longitudinal beam 105 is also provided in the upper frame 1, and the reinforcing longitudinal beam 105 is connected between the upper cross beam 104 adjacent to the upper front edge beam 1012, that is, the first upper cross beam 1041 and the upper front edge beam 1012. The reinforcing side members 105 are arranged in the vehicle body front-rear direction, and as a preferred embodiment, reinforcing side members 105 are provided on both the left and right sides of the center tunnel 103. By providing the reinforcing side member 105, the present embodiment is advantageous in that the frontal collision force is transmitted to the rear upper cross member 104 more favorably, and the frontal collision safety can be further improved.

In this embodiment, the lower side beam 2011 is inclined toward one side of the battery module installation space 10, so that more safety spaces can be provided for the battery module 20 during collision, stress on the battery module 20 is reduced, and safety of the battery module can be improved. Of course, the cross section of each lower side edge beam 2011 is trapezoidal, so that the characteristic of large strength of a trapezoidal structure can be utilized, the structural strength of the lower side edge beam 2011 is improved, the overall structural strength of the lower frame 2 is further ensured, and the capability of dealing with column collision and side collision is improved.

In particular, each part of the frame structure of the battery pack of this embodiment can be made of any suitable material. Furthermore, as a preferred embodiment, the upper frame 101, the lower frame 201, the upper cross member 104, the lower cross member 202 and the middle channel 103 in the present embodiment may be made of roll members and connected by welding.
