[0034] In this embodiment, the battery pack for vertical installation is improved by adding a reinforcing frame 12, which is connected to the bottom wall 112 of the receiving groove 111 of the housing body 11. This improves the structural strength of the housing body 10. At the same time, the battery pack 20 is installed on the bottom wall 112 of the receiving groove 111, and the groove wall of the receiving groove abuts against the reinforcing frame 12 installed on the groove wall of the receiving groove 111, thereby improving the support strength of the housing body 10 for the battery pack 20 and realizing the vertical installation of the battery pack.

[0035] It should be noted that the vertical installation in this embodiment refers to the installation of the battery pack along the direction of a set of oppositely arranged groove walls of the receiving groove 111, specifically the X direction in the figure, rather than the vertical direction of the bottom wall 112 of the groove. The vertical direction of the bottom wall 112 of the groove is the direction in which the battery pack 20 is installed, which is the wall surface with the largest area of ​​the battery pack.

[0036] Specifically, the box body 11 includes a bottom wall 112, two first side walls 113 and two second side walls 114. The bottom wall 112, the two first side walls 113 and the two second side walls 114 enclose the box body 11 with the receiving groove 111. The battery pack 20 and the reinforcing frame 12 are fixed to the bottom wall 112, and the reinforcing frame 12 is located on the side of the first side wall 113 and the second side wall 114 away from the bottom wall 112, that is, close to the opening, thereby improving the structural strength of the entire box body 10.

[0037] Specifically, in this embodiment, vertical installation means that the battery pack is installed along the relative orientation of the two first sidewalls 113 of the receiving groove 111, specifically in the X direction shown in the figure.

[0038] Optionally, the housing 10 includes a fixing beam 13, which is disposed on the bottom wall 112 of the receiving groove 111. The fixing beam 13 is used to connect the reinforcing frame 12 and the battery pack 20. The fixing beam 13 not only improves the structural strength of the housing 11, but also fixes the reinforcing frame 12 and the battery pack 20 and other structures installed in the receiving groove 111.

[0039] Specifically, multiple fixed beams 13 are provided, specifically at the connection between the first side wall 113 and the bottom wall 112, the connection between the second side wall 114 and the bottom wall 112, and the location where the battery pack 20 is installed and fixed, etc.

[0040] Optionally, the housing 10 further includes a fixing part 14, which is disposed on the outside of the first side wall 113, and the mounting surface of the fixing part 14 is parallel to the first side wall 113. The fixing part 14 is used to connect with an external connection structure to realize the installation of the battery pack along the X direction.

[0041] Furthermore, the reinforcing frame 12 includes a connecting frame 121 and a fixing frame 122. The fixing frame 122 is disposed on the side of the groove wall of the receiving groove 111 away from the bottom wall 112 of the groove. The two ends of the connecting frame 121 are respectively connected to the bottom wall 112 of the receiving groove 111 and the fixing frame 122, thereby realizing the fixing and installation of the reinforcing frame 12.

[0042] Optionally, the connection between the connecting frame 121 and the fixed frame 122 can be achieved by bolting or welding the connecting frame 121 and the bottom wall 112 of the receiving groove 111.

[0043] Specifically, the fixed frame 122 includes two first longitudinal beams 1221 and two first transverse beams 1222, which are vertically connected. The receiving slot 111 includes two first sidewalls 113 and two second sidewalls 114, which are vertically connected. The first sidewalls 113 and the second sidewalls 114 are located on the side of the first sidewall 113 away from the bottom wall 112 of the receiving slot 111, and the first transverse beams 1222 are located on the side of the second sidewall 114 away from the bottom wall 112 of the receiving slot 111. The battery pack 20 abuts against the first longitudinal beams 1221. By setting the first crossbeam 1222 and the first longitudinal beam 1221, the housing 10 is provided with a reinforcing structure at the opening of the first side wall 113 and the second side wall 114, thereby improving the structural strength of the entire housing 10. The first longitudinal beam 1221 is used to support the battery pack 20, which can realize the supporting function of the battery pack 20 when the battery pack is installed vertically.

[0044] Optionally, at least two battery packs 20 are provided, and the fixing frame 122 further includes at least one second longitudinal beam 1223. The second longitudinal beam 1223 is parallel to the first longitudinal beam 1221 and its two ends are respectively connected to two first cross beams 1222. The second longitudinal beam 1223 divides the receiving slot 111 into at least two battery slots. Battery packs 20 are installed in the battery slots. One of the at least two battery packs 20 abuts against the first longitudinal beam 1221, and the rest abut against the corresponding second longitudinal beam 1223. That is, if at least two battery packs 20 are provided, except for the battery pack 20 at the bottom along the X direction which abuts against the first longitudinal beam 1221 for support, the other battery packs 20 in the X direction are supported by the second longitudinal beam 1223, so as to ensure the support of each battery pack 20 in the X direction, that is, to ensure the support of each battery pack 20 in the vertical direction.

[0045] Optionally, the first crossbeam 1222 and the first longitudinal beam 1221, as well as the first crossbeam 1222 and the second longitudinal beam 1223, are fixedly connected by welding to achieve the connection of the entire reinforcing frame 12, thereby improving the structural strength of the box 10.

[0046] Specifically, the connecting frame 121 includes multiple connecting beams 1211, which are evenly distributed between the bottom wall 112 of the receiving groove 111 and the fixed frame 122. The arrangement of multiple connecting beams 1211 ensures the connection stability between the fixed frame 122 and the bottom wall 112 of the receiving groove 111, thereby improving the structural strength of the box 10 and the load-bearing capacity of the fixed frame 122 for the battery pack 20.

[0047] Optionally, the battery pack 20 includes a plurality of cells 21, wherein the cells 21 are relatively narrow to ensure that they can be installed in the box 10 with a narrow lateral space.

[0048] Furthermore, the battery pack for vertical installation also includes a cold plate structure 40, which is disposed between the battery pack 20 and the bottom wall 112 of the receiving slot 111. The cold plate structure 40 is used to cool the battery pack 20, so that the ambient temperature of the battery pack 20 meets the operating range, effectively heats up the battery pack, improves the energy density and range of the battery pack, and thus enhances the performance and safety of the whole vehicle.

[0049] It should be noted that the commonly used cold plate structure 40 can be selected. It is connected to the external liquid supply device through water circuit connectors and pipes, thereby realizing the supply of coolant to the inside of the cold plate structure 40. Its specific structure will not be described in detail here.

[0050] Optionally, the cold plate structure 40 is also provided with a heating element for heating the battery pack 20. Integrating the heating element into the cold plate structure 40 improves volume utilization and energy density, reduces the number of parts, and makes assembly more convenient.
