[0022] In related technologies, during the assembly of power batteries, multiple individual components such as busbars, wiring harness assemblies, water pipe assemblies, liquid cooling connectors, and quick-change connectors are typically installed on the battery separately. This increases the number of installation stations and complicates the process. In addition, this installation method may also lead to problems such as low installation accuracy and low efficiency.

[0023] To address the problems existing in the aforementioned related technologies, this utility model provides an integrated bracket, battery pack, and vehicle.

[0024] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an integrated bracket according to an embodiment of the present invention includes a mounting plate 1 and a fixing structure 2. The fixing structure 2 is disposed on one side of the mounting plate 1 and is used to fix the busbar 300 and / or wiring harness assembly 400 of the battery pack. The mounting plate 1 includes a first mounting part 11 and a second mounting part 12. The first mounting part 11 is used to install the quick-change connector 100 of the battery pack, and the second mounting part 12 is used to install the liquid-cooled quick-change connector 200 of the battery pack.

[0025] It should be noted that the quick-change connector 100 of the battery pack is the external interface of the battery pack, used to realize the electrical connection between the battery pack and external electrical components; the liquid-cooled quick-change connector 200 is located at the inlet and outlet of the liquid-cooling plate, used to connect the inlet and outlet water pipes (i.e., Figure 5 Water pipe assembly 500 (in the middle).

[0026] Specifically, the mounting plate 1 is roughly square in shape and is used to be installed inside the battery pack housing, located between the side panel of the battery pack housing and the battery module. Figure 1The side with the Z-axis pointing upwards (i.e., the upper side of mounting plate 1) faces the cover plate of the battery pack housing. Mounting plate 1 is located at... Figure 1 The side of the mounting plate facing away from the cover plate of the battery pack housing (i.e., the lower side of the mounting plate 1) is opposite to the cover plate of the battery pack housing. In other words, the mounting plate 1 is set horizontally inside the battery pack housing, with the upper side of the mounting plate 1 facing the cover plate of the battery pack housing and the lower side of the mounting plate 1 facing away from the cover plate of the battery pack housing. The fixing structure 2 is located on the side of the mounting plate 1 facing away from the cover plate of the battery pack housing, that is, on the lower side of the mounting plate 1.

[0027] More specifically, the mounting plate 1 includes a first mounting portion 11 for mounting a quick-change connector 100 for mounting a battery pack and a second mounting portion 12 for mounting a liquid-cooled quick-change connector 200 for mounting a battery pack. The first mounting portion 11 and the second mounting portion 12 are arranged horizontally, and the quick-change connector 100 and the liquid-cooled quick-change connector 200 can be mounted on the upper end of the mounting plate 1 using fasteners such as bolts (i.e., the mounting plate 1 is located at...). Figure 1 The end with the Z-axis pointing positively upwards). Meanwhile, the lower end of mounting plate 1 (i.e., where mounting plate 1 is located) Figure 1 A fixing structure 2 is provided at one end (opposite to the Z-axis) for fixing the busbar 300 and / or wiring harness assembly 400 of the battery pack arranged below the mounting plate 1. The fixing structure 2 can be provided at the lower end of the first mounting part 11 and / or the second mounting part 12, for example, Figure 2 The example given shows that both the lower ends of the first mounting part 11 and the second mounting part 12 are provided with fixing structures 2. The busbar 300 and / or the wire harness assembly 400 can be fixed to the fixing structure 2 using, for example, a cable tie 600. The fixing structure 2 can be a slot for engaging with the snap-fit ​​portion 620 of the cable tie 600. In this case, the cable tie 600 is a round hole type cable tie or a waist hole type cable tie, and the snap-fit ​​portion 620 of the cable tie 600 is a snap-fit ​​structure. The fixing structure 2 can also be a plate for engaging with the snap-fit ​​portion 620 of the cable tie 600, such as... Figure 5 As shown, at this time, the cable tie 600 is a steel plate type cable tie, and the buckle part 620 of the cable tie 600 is a clip for clamping onto the plate, which is not specifically limited here.

[0028] In this embodiment, by configuring the mounting plate 1 to include a first mounting portion 11 for mounting the quick-change connector 100 of the battery pack and a second mounting portion 12 for mounting the liquid-cooled quick-change connector 200 of the battery pack, the mounting plate 1 can provide mounting and fixing points for the quick-change connector 100 and the liquid-cooled quick-change connector 200 of the battery pack. At the same time, by providing a fixing structure 2 for mounting the busbar 300 and / or wiring harness assembly 400 of the battery pack at the lower end of the mounting plate 1, the mounting plate 1 can also provide mounting and fixing points for the busbar 300 and / or wiring harness assembly 400 of the battery pack. In this way, when assembling the battery pack, the quick-change connector 100 and the liquid-cooled quick-change connector 200 of the battery pack can be installed on, for example, the upper end of the integrated bracket, and the busbar 300 and / or wiring harness assembly 400 of the battery pack can be installed on, for example, the lower end of the integrated bracket. Then, the entire assembly is installed onto the battery pack housing. This allows the busbar 300 and / or wiring harness assembly 400 of the battery pack to be integrated with the quick-change connector 100 and the liquid-cooled quick-change connector 200 on the same bracket. This eliminates the need to use separate brackets for each of the quick-change connector 100, the liquid-cooled quick-change connector 200, the busbar 300, and the wiring harness assembly 400 when installing them onto the battery pack housing. This not only improves the assembly efficiency of the battery pack but also increases the integration of the integrated bracket, reduces the number of parts, and lowers material management costs. Furthermore, by setting the fixing structure 2 on one side of the mounting plate 1, for example, on the lower side of the mounting plate 1, the bottom space of the mounting plate 1 can be fully utilized to arrange the busbar 300 of the battery pack and / or the wiring harness assembly 400, thereby improving space utilization.

[0029] Optionally, combined Figure 1 and Figure 4 As shown, the first mounting part 11 has a first mounting surface 111 on the side away from the fixed structure 2, and the second mounting part 12 has a second mounting surface 121 on the side away from the fixed structure 2. The first mounting surface 111 and the second mounting surface 121 are used to mount the quick-change connector 100 and the liquid-cooled quick-change connector 200, respectively, and the height of the first mounting surface 111 is lower than the height of the second mounting surface 121.

[0030] It should be noted that the mounting plate 1 is roughly horizontally set inside the battery pack housing. If the horizontal plane where the lower surface of the mounting plate 1 is located is taken as the reference plane, then the height of the first mounting surface 111 refers to the distance between the first mounting surface 111 and the reference plane, and the height of the second mounting surface 121 refers to the distance between the second mounting surface 121 and the reference plane. The fact that the height of the first mounting surface 111 is lower than the height of the second mounting surface 121 can be understood as the distance from the first mounting surface 111 to the reference plane being less than the distance from the second mounting surface 121 to the reference plane.

[0031] Since the quick-change connector 100 has a boss structure at the mounting hole, and this boss structure is located on the mounting side of the quick-change connector 100 (i.e. the side of the quick-change connector 100 used to connect with the first mounting part 11), if the first mounting surface 111 and the second mounting surface 121 are set flush, the quick-change connector 100 will occupy more space at the upper end of the integrated bracket. Therefore, in this optional embodiment, by setting the height of the first mounting surface 111 used to install the quick-change connector 100 to be lower than the height of the second mounting surface 121 used to install the liquid-cooled quick-change connector 200, the first mounting surface 111 is lower than the second mounting surface 121. In this way, the height of the quick-change connector 100 above the second mounting surface 121 can be reduced, thereby reducing the space occupied by the quick-change connector 100 and facilitating its arrangement.

[0032] Furthermore, combined Figure 1 and Figure 4 As shown, the first mounting surface 111 is provided with a first mounting hole 112 for mounting the quick-connect connector 100; and / or, the second mounting surface 121 is provided with a second mounting hole 122 for mounting the liquid-cooled quick-connect connector 200. Thus, by using fasteners such as bolts at the first mounting hole 112 and the second mounting hole 122 to respectively mount the quick-connect connector 100 and the liquid-cooled quick-connect connector 200 on the integrated bracket, the quick-connect connector 100 and the liquid-cooled quick-connect connector 200 are respectively mounted and fixed on the integrated bracket.

[0033] Furthermore, combined Figure 1 and Figure 3 As shown, the mounting plate 1 has a third mounting hole 14, which is used to detachably connect to the battery pack housing via fasteners. This allows the integrated bracket to be fixedly mounted on the battery pack housing.

[0034] Furthermore, combined Figure 1 and Figure 3 As shown, the mounting plate 1 also includes a connecting portion 13 disposed between the first mounting portion 11 and the second mounting portion 12. The upper end surface of the connecting portion 13 is inclined, and the first mounting surface 111 and the second mounting surface 121 are respectively connected to the opposite ends of the inclined surface. In this way, connecting the first mounting portion 11 and the second mounting portion 12 through the connecting portion 13 not only increases the connection strength between the first mounting portion 11 and the second mounting portion 12, but also increases the safety distance between the quick-change connector 100 and the liquid-cooled quick-change connector 200, avoiding mutual interference between the two. Moreover, by setting the upper end surface of the connecting portion 13 as an inclined surface, the material consumption of the mounting plate 1 is saved while increasing the safety distance, reducing production costs. In addition, it is also convenient to set more reinforcing ribs 4 on the lower end surface of the inclined connecting portion 13 to improve the structural strength of the connecting portion 13.

[0035] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the first mounting surface 111 is provided with a first clearance hole 113, which is used for the quick-change connector 100 to pass through the mounting plate 1. In this way, on the one hand, it is convenient to install the quick-change connector 100, and on the other hand, it can further reduce the space occupied by the quick-change connector 100, making the overall structure of the integrated bracket with the quick-change connector 100 installed more compact, so as to facilitate the arrangement.

[0036] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the second mounting surface 121 is provided with a second clearance hole 123, which is used for the liquid-cooled quick-connect connector 200 to pass through the mounting plate 1 and connect to the water pipe assembly 500. In this way, on the one hand, it is convenient to install the liquid-cooled quick-connect connector 200, and on the other hand, it can reduce the space occupied by the liquid-cooled quick-connect connector 200, making the overall structure of the integrated bracket with the liquid-cooled quick-connect connector 200 more compact, so as to facilitate the arrangement. At the same time, the water pipe assembly 500 can also be arranged at the bottom of the integrated bracket to further improve the space utilization.

[0037] Optionally, combined Figure 1 and Figure 3 As shown, the edge of the first mounting surface 111 is provided with a flange structure 114, and the flange structure 114 is located on the side of the mounting plate 1 facing away from the fixing structure 2. In this way, the flange structure 114 can be used to improve the structural strength of the first mounting part 11. Moreover, by placing the flange structure 114 on the side of the mounting plate 1 facing away from the fixing structure 2, for example, at the upper end of the mounting plate 1, interference between the flange structure 114 and the busbar 300 and wiring harness assembly 400 arranged below the mounting plate 1 can be avoided. Furthermore, since the first mounting surface 111 is lower than the second mounting surface 121, by only placing the flange structure 114 around the first mounting surface 111 and ensuring that the flange structure 114 is not higher than the second mounting surface 121, the space at the upper end of the first mounting surface 111 can be effectively utilized, while avoiding increasing the vertical dimension of the mounting plate 1.

[0038] Optionally, combined Figure 2 and Figure 5 As shown, the fixing structure 2 includes a first fixing structure 21 and a second fixing structure 22. The first fixing structure 21 and the second fixing structure 22 are respectively used to engage with the cable ties 600 that are tied to the positive output busbar 310 and the negative output busbar 320 of the busbar 300.

[0039] In this optional embodiment, the busbar 300 includes a positive output busbar 310 and a negative output busbar 320. A first fixing structure 21 is used to engage with a cable tie 600 bound to the positive output busbar 310, and a second fixing structure 22 is used to engage with a cable tie 600 bound to the negative output busbar 320. The cable tie 600 includes a cable tie body 610 and a snap-fit ​​portion 620. The cable tie body 610 is bound to the positive output busbar 310 and the negative output busbar 320, and the first fixing structure 21 and the second fixing structure 22 are respectively engaged with the snap-fit ​​portion 620 of the corresponding cable tie 600. In this way, the positive output busbar 310 and the negative output busbar 320 of the busbar 300 are respectively fixed to the integrated bracket by snap-fit, thereby improving the convenience of installation. In addition, multiple first fixing structures 21 and second fixing structures 22 can be provided respectively, so as to provide multiple fixing points for the positive output bus 310 and the negative output bus 320, thereby improving the firmness of the bus on the integrated bracket.

[0040] Optionally, combined Figure 2 and Figure 6 As shown, the fixing structure 2 includes a third fixing structure 23, which is used to snap onto the cable ties 600 bundled on the wire harness assembly 400. This snap-on method secures the wire harness assembly 400 to the integrated bracket, improving installation convenience.

[0041] Optionally, combined Figure 2 , Figure 5 and Figure 6 As shown, the fixing structure 2 includes a first fixing structure 21, a second fixing structure 22, and a third fixing structure 23. The first fixing structure 21 and the second fixing structure 22 are arranged opposite to each other, and the third fixing structure 23 is located between the first fixing structure 21 and the second fixing structure 22. This allows for the arrangement of the busbar 300 and the wiring harness assembly 400 on the integrated bracket by placing the positive output busbar 310 and the negative output busbar 320 on opposite sides of the lower end of the integrated bracket, and placing the wiring harness assembly 400 between the positive output busbar 310 and the negative output busbar 320. Furthermore, this also facilitates the routing of the wiring harness assembly 400.

[0042] Optionally, combined Figure 2 and Figure 5 As shown, the first fixing structure 21 includes a first snap-fit ​​portion 211 and a first flange portion 212. The first snap-fit ​​portion 211 has a first flange portion 212 at each of its opposite ends. One end of the first snap-fit ​​portion 211 and the two first flange portions 212 are connected to the mounting plate 1. The first snap-fit ​​portion 211 is used to snap-fit ​​with the cable tie 600 that is tied to the positive output busbar 310.

[0043] In this optional embodiment, the cross-section of the first fixing structure 21 is approximately U-shaped, wherein the first snap-fit ​​portion 211 forms the bottom edge of the U-shape, and the two first flange portions 212 respectively form the two vertical sides of the U-shape. One end of the first snap-fit ​​portion 211 and the two first flange portions 212 along the axial direction of the U-shape are connected to the mounting plate 1. The cable tie 600 binding the positive output busbar 310 is a steel plate type cable tie, that is, the buckle portion 620 of the cable tie 600 is a clip and is used to clamp onto the first snap-fit ​​portion 211 of the first fixing structure 21. In this way, the positive output busbar 310 is fixed to the first fixing structure 21 by the cable tie 600. Moreover, by providing the first flange portions 212 at opposite ends of the first snap-fit ​​portion 211, the rigidity of the first fixing structure 21 is improved by using the first flange portions 212, ensuring the stability of the positive output busbar 310 fixed to the first fixing structure 21. In addition, compared with the "I" shaped cross-section, the cross-section of the first fixing structure 21 is set to a U-shaped structure, so that the positive output bus 310 can be fixed on the side of the first snap-fit ​​part 211 away from the two first flange parts 212, which facilitates the arrangement of the positive output bus 310.

[0044] Optionally, combined Figure 2 and Figure 5 As shown, the second fixing structure 22 includes a second snap-fit ​​portion 221 and a second flange portion 222. The second snap-fit ​​portion 221 has a second flange portion 222 at each of its opposite ends. One end of the second snap-fit ​​portion 221 and the two second flange portions 222 are connected to the mounting plate 1. The second snap-fit ​​portion 221 is used to snap into the cable tie 600 that is tied to the negative output busbar 320. The second fixing structure 22 has the same structure as the first fixing structure 21, and its structure will not be described in detail here. This allows the negative output busbar 320 to be fixed to the second fixing structure 22 by the cable tie 600. Furthermore, by providing second flange portions 222 at each of the opposite ends of the second snap-fit ​​portion 221, the rigidity of the second fixing structure 22 is increased, ensuring the stability of the negative output busbar 320 fixed to the second fixing structure 22. In addition, compared with the "I" shaped cross-section, the cross-section of the second fixing structure 22 is set to a U-shaped structure, so that the negative output bus 320 can be fixed on the side of the second snap-fit ​​part 221 away from the two second flange parts 222, which facilitates the arrangement of the negative output bus 320.

[0045] Optionally, combined Figure 2 As shown, the third fixing structure 23 is a slot structure. The slot structure may or may not penetrate the mounting plate 1, for example... Figure 2 and Figure 3An example of a slot structure penetrating the mounting plate 1 is given. In this way, it is not only convenient to use round hole type cable ties or waist hole type cable ties to fix the wire harness assembly 400 to the lower end of the mounting plate 1, but the slot structure can also be used as a weight-reducing hole to reduce weight.

[0046] Optionally, combined Figure 2 As shown, the integrated bracket also includes a positioning structure 3, which is located on the side of the mounting plate 1 where the fixing structure 2 is located, and is used to position and cooperate with the battery pack housing. Thus, during battery pack assembly, the positioning structure 3 can be used to position and connect with the battery pack housing to improve the installation accuracy of the integrated bracket, ensuring the accurate installation position of the integrated bracket, and consequently ensuring the accurate installation position of external output components such as the quick-change connector 100 and the liquid-cooled quick-change connector 200 installed on the integrated bracket.

[0047] Furthermore, combined Figure 2 As shown, the positioning structure 3 includes two positioning posts, which are respectively located at opposite ends of the mounting plate 1 and are used to insert into the positioning holes on the battery pack housing.
