[0038] This application provides an integrated panel and battery pack. By setting crossbeams and reinforcing ribs between the front panel and the front end panel, and molding these components in one piece, the strength of the panel and battery pack is increased, the number of parts is reduced, and the assembly steps and difficulty are lowered.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] like Figures 3-5 As shown, the integrated panel 2 provided in this application has a length direction as a first direction, a width direction as a second direction, and a third direction perpendicular to both the first and second directions. The integrated panel 2 includes:

[0041] The front panel 201 and the front panel 202 are positioned relative to each other, and there is a gap between the front panel 201 and the front panel 202 in a third direction.

[0042] A crossbeam 203 is disposed between the front panel 201 and the front end plate 202;

[0043] A reinforcing rib 206 is provided between the front panel 201 and the front end plate 202;

[0044] The front panel 201, the front end plate 202, the crossbeam 203, and the reinforcing rib 206 are integrally formed.

[0045] This application increases the structural strength of the panel by setting a crossbeam 203 and a reinforcing rib 206 between the front panel 201 and the front end plate 202 and molding these components into one piece; since the panel will be assembled into a battery pack, the structural strength of the battery pack is increased; the one-piece panel reduces the number of parts of the panel and the battery pack, and there is no need to assemble the one-piece panel 2 itself during assembly. It is only necessary to assemble the one-piece panel 2 into the battery box 1 of the battery pack, which reduces the assembly steps and difficulty.

[0046] In a preferred embodiment, such as Figures 3-5 As shown, the crossbeam 203 is disposed between the front panel 201 and the front end plate 202 and extends along the first direction, that is, the length direction of the crossbeam 203 is parallel to the first direction, while the width direction of the crossbeam 203 is consistent with the third direction. In other words, the crossbeam 203 can be set perpendicular to the front panel 201 and the front end plate 202. Of course, the crossbeam 203 can also be set to have an angle with both the front panel 201 and the front end plate 202, as long as the length direction of the crossbeam 203 is approximately extended along the first direction. The reinforcing rib 206 is disposed between the front panel 201 and the front end plate 202 and extends along the second direction. The reinforcing rib 206 is intersected with the crossbeam 203 and evenly distributed along the length of the crossbeam 203. In this way, the crossbeam 203 and the reinforcing rib 206 can form a mesh, which improves the overall strength of the integrated panel 2; the front panel 201 and the front end plate 202 are also provided with side plates between their two ends in the first direction. One side plate can connect the front panel 201 and the front end plate 202 at one end in the first direction, and the other side plate can connect the front panel 201 and the front end plate 202 at the other end in the first direction, so that the front panel 201, the front end plate 202 and the side plates form a closed structure, which further increases the structural strength; the front panel 201, the front end plate 202, the crossbeam 203, the reinforcing rib 206 and the side plates are integrally formed, which further increases the structural strength, reduces the number of parts and saves assembly procedures.

[0047] This application also provides a battery pack, such as Figure 1 , Figure 2 and Figure 6As shown, the device includes an integrated panel 2, a battery housing 1, a water inlet pipe 4, and a water outlet pipe 5. The battery housing 1 has a panel mounting space. The water inlet pipe 4 and the water outlet pipe 5 are both located in the panel mounting space and are connected to the cooling pipes inside the battery housing 1, thereby achieving cooling of the battery housing 1 and the battery cells inside. The integrated panel 2 can be installed in the panel mounting space and can cover the water inlet pipe 4 and the water outlet pipe 5.

[0048] The battery pack of this application increases the strength of the battery pack, reduces the number of parts, and lowers the assembly steps and difficulty by using the aforementioned integrated panel 2. The integrated panel 2 can be installed in the panel mounting space and achieve a fixed connection with the battery box 1. The integrated panel 2 is supported and connected by a mesh structure composed of crossbeams 203 and reinforcing ribs 206. There are hollow parts in this mesh structure, or some reinforcing ribs 206 can be removed, thereby creating clearance space for the water inlet pipe 4 and the water outlet pipe 5, so that the integrated panel 2 can cover the water inlet pipe 4 and the water outlet pipe 5 without occupying additional space in the battery box 1, thus saving space inside the battery box 1.

[0049] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, the battery housing 1 includes a first housing side beam 101, a second housing side beam 102, and a bottom cold plate 103. The first housing side beam 101 and the second housing side beam 102 are respectively arranged on both sides of the bottom cold plate 103 in a first direction and form a U-shaped structure. The first housing side beam 101, the second housing side beam 102, and the bottom cold plate 103 form an opening at one end in a third direction. The panel mounting space is located at the opening, and the integrated panel 2 is installed in the panel mounting space. In this way, the integrated panel 2 forms the end plate of the battery housing 1 in a third direction. The front panel 201 of the integrated panel 2 can be exposed to the outside of the battery housing 1 through the above-mentioned opening, forming a panel structure that can be interactively operated.

[0050] In a preferred embodiment, such as Figures 1-3As shown, the bottom cold plate 103 is equipped with the aforementioned cooling pipes. The inlet pipe 4 and outlet pipe 5 are installed on the bottom cold plate 103 and are connected to the cooling pipes respectively. The front panel 201 is provided with a water nozzle clearance port 205. A clearance space corresponding to the water nozzle clearance port 205 is also provided between the front panel 201 and the front end plate 202. When the integrated panel 2 is installed in the panel installation space, the inlet pipe 4 and outlet pipe 5 are located in the clearance space. The water inlet connector 401 of the inlet pipe 4 and the water outlet connector 501 of the outlet pipe 5 can extend out of the battery box 1 through the water nozzle clearance port 205 and connect to the cooling liquid source. In this embodiment, the water inlet connector 401 of the inlet pipe 4 and the water outlet connector 501 of the outlet pipe 5 extend out of the battery box 1 through the water nozzle clearance port 205. The water inlet connector 401 and the water outlet connector 501 are separately installed from the front panel 201, which does not require high installation precision and reduces the installation difficulty.

[0051] In a preferred embodiment, such as Figure 1 and Figure 8 As shown, the battery pack also includes a panel cover 6, which has an inlet opening 601 and an outlet opening 602. The inlet opening 601 and the outlet opening 602 are respectively fitted onto the inlet connector 401 and the outlet connector 501. The panel cover 6 is fixedly connected to the inlet pipe 4 and the outlet pipe 5. The shape of the panel cover 6 is consistent with the shape of the water nozzle clearance opening 205, and the panel cover 6 is coplanar with the front panel 201.

[0052] The panel cover 6 can prevent dust from entering the battery box 1 through the water nozzle avoidance port 205, and can also serve as the positioning structure of the front panel 201 when the integrated panel 2 is installed. After the water inlet opening 601 and the water outlet opening 602 are respectively fitted onto the water inlet connector 401 and the water outlet connector 501, the water inlet opening 601 is welded to the water inlet connector 401 and the water outlet opening 602 is welded to the water outlet connector 501 to achieve a fixed connection between the panel cover 6 and the water inlet pipe 4 and the water outlet pipe 5.

[0053] In a preferred embodiment, such as Figure 8 As shown, the edge of the panel cover 6 is provided with a welding bevel, which increases the welding area when the panel cover 6 is welded to the front panel 201, thereby reducing the welding difficulty.

[0054] In a preferred embodiment, such as Figures 3-5 As shown, in order to reduce the difficulty of welding, welding bevels 204 are provided at the edges where the front panel 201 and the front end plate 202 abut against the battery box 1, and the front panel 201 and the front end plate 202 are welded to the battery box 1 at the welding bevels 204.

[0055] Specifically, the welding bevel 204 is set at the edge of the front panel 201 in the first direction and the edge of the second direction, as well as at the edge of the front panel 202 in the first direction and the edge of the second direction. The lines at these edges are changed to surfaces, and there is an angle between them and the surface of the front panel 201 or the front surface. In this way, the contact area between the integrated panel 2 and the battery box 1 is large, which can increase the welding strength and reduce the welding difficulty.

[0056] In a preferred embodiment, such as Figure 6 and Figure 7 As shown, in order to protect and isolate the surface of the front panel 202 that is opposite to the battery cell, the battery pack also includes an end plate cover 3. The surface of the front panel 202 away from the front panel 201 is provided with a cover plate mounting hole 2021. The end plate cover 3 is provided with a mounting post 301. The mounting post 301 can be inserted into the cover plate mounting hole 2021 and the end plate cover 3 is placed on the front panel 202.

[0057] In a preferred embodiment, such as Figure 5 As shown, the front panel 202 has a reinforcing support grid on its surface away from the front panel 201. The cover plate mounting hole 2021 is located at the intersection of the reinforcing support grid. When the mounting post 301 is inserted into the cover plate mounting hole 2021, the surface of the end plate cover 3 can abut against the reinforcing support grid.

[0058] The reinforced support grid increases the thickness of the front plate 202, so that the plug-in post will not penetrate the front plate 202. In addition, the end plate cover 3 is not only connected and fixed to the front plate 202 by several mounting posts 301, but also allows the surface of the end plate cover 3 to abut against the reinforced support grid, increasing the contact area between the two and avoiding damage caused by excessive local pressure.

[0059] This application also provides a method for assembling a battery pack, the assembly steps of which include:

[0060] Weld the inlet pipe 4 and the outlet pipe 5 to the battery box 1;

[0061] Connect the inlet opening 601 of the panel plug 6 to the inlet connector 401, and the outlet opening 602 to the outlet connector 501. Then weld the panel plug to the inlet pipe 4 and the outlet pipe 5.

[0062] By positioning and cooperating with the panel plug 6 through the water tap clearance 205 of the integrated panel, the integrated panel is installed in the panel installation space. At this time, the clearance space of the integrated panel covers the water inlet pipe 4 and the water outlet pipe 5.

[0063] The integrated panel is welded to the battery box 1 and to the panel cover 6 respectively;

[0064] Install and plug the end plate cover 3 into the front end plate 202.

[0065] The battery pack assembly method described in this application has few steps and is easy to assemble.
