[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] This embodiment relates to a mounting structure, which is arranged in a battery pack. In terms of overall structure, the mounting structure includes a base 1 mounted on the battery pack shell, and a mounting frame 2 rotatably arranged on the base 1, and the mounting frame 2 is provided with a plurality of mounting parts for mounting a wiring harness or a copper busbar. A suspension part is provided between the base 1 and the mounting frame 2, and the suspension part can suspend the rotating mounting frame 2 at a preset position.

[0040] The mounting structure described in this embodiment is achieved by rotatably setting the mounting frame 2 on the base 1, and setting a mounting portion for mounting a wiring harness or a copper busbar on the mounting frame 2, and setting a hovering portion between the base 1 and the mounting frame 2. By rotating the mounting frame 2 and hovering it at a preset position, the position of the mounting portion can be changed, thereby improving the versatility of the mounting structure and further reducing production costs.

[0041] Based on the above overall introduction, an exemplary structure of the installation structure in this embodiment is as follows: Figures 1 to 3As shown in . The base 1 in this embodiment has a connecting portion 101 connected to the battery pack housing, and a mounting portion 102 bent relative to the connecting portion 101, and the mounting frame 2 is rotatably arranged on the mounting portion 102. The arrangement of the connecting portion 101 and the mounting portion 102 facilitates the installation of the base 1 on the battery pack housing and also facilitates the installation of the mounting frame 2 on the base 1.

[0042] like Figure 5 As shown in , the mounting portion 102 and the connecting portion 101 are connected so that the base 1 is in an "L" shape. The structure of the base 1 here is simple and easy to process and form, which is beneficial to reduce production costs. To further improve the flexibility of use of the mounting structure. An elongated hole 1011 is provided on the connecting portion 101, and the base 1 is connected to the battery pack shell by a connector passing through the elongated hole 1011. The elongated hole 1011 here extends along the length direction of the connecting portion 101. By changing the position where the connector passes through the elongated hole 1011, the base 1 can be installed on the battery pack shell according to the use requirements, thereby having better flexibility of use. In specific implementation, the connector can adopt a structure with a connecting function such as a screw.

[0043] As a preferred embodiment, the mounting frame 2 in this embodiment is in the shape of a straight line, and at least one mounting portion is provided at both ends of the mounting frame 2. Figure 1 and Figure 6 As shown in , the middle part of the mounting frame 2 is rotatably connected to the base 1. Preferably, mounting parts are respectively provided at both ends of the mounting frame 2. Here, the mounting frame 2 has a simple structure, is easy to process, and has a good use effect. It can be understood that the mounting frame 2 in this embodiment can also be in other structural forms, and the number of mounting parts can also be determined according to the use requirements.

[0044] The mounting portion in this embodiment is a mounting hole 201, and a mounting piece with a clamping portion is provided on the copper bar or the wiring harness, and the copper bar or the wiring harness is mounted on the mounting frame 2 by clamping the mounting hole 201 with the clamping portion. The mounting frame 2 here can be a product in the prior art, such as a wiring harness mounting seat, and the clamping portion is a clamping head provided on the mounting piece. The clamping head passes through the mounting hole 201 from one side of the mounting frame 2 and is clamped on the other side of the mounting frame 2, so that the arrangement and fixation of the wiring harness or the copper bar can be completed. The mounting portion in this embodiment can be used to fix the wiring harness, and can also be used to fix the copper bar. When it is specifically implemented, it can be determined according to the layout requirements.

[0045] In this embodiment, one of the base 1 and the mounting frame 2 is provided with a connecting shaft 1031, and the other of the two is provided with a connecting groove 2021, and the connecting shaft 1031 is inserted into the connecting groove 2021 and can rotate relative to the connecting groove 2021. The suspension portion is provided between the connecting shaft 1031 and the inner peripheral wall of the connecting groove 2021.

[0046] Here, the setting of the connecting shaft 1031 and the connecting groove 2021 is not only simple in structure, but also convenient for the mounting frame 2 to be rotatably set on the base 1. The hovering portion is set between the connecting shaft 1031 and the inner peripheral wall of the connecting groove 2021, which is convenient for improving the hovering setting of the mounting frame 2.

[0047] Further, the suspension part includes a plurality of protrusions 1032 arranged at intervals on the outer peripheral wall of the connecting shaft 1031 and the inner peripheral wall of the connecting groove 2021 in a circumferential direction, and a groove 2022 arranged on the other side thereof and corresponding to the protrusions 1032. Each protrusion 1032 can be rotated into or out of the corresponding groove 2022, or each protrusion 1032 can be inserted into the corresponding groove 2022. In the suspension part, by rotating the plurality of protrusions 1032 into or out of the plurality of grooves 2022, or inserting the protrusions 1032 into the corresponding grooves 2022, the mounting frame 2 can be rotated to a preset position and maintained, so that the mounting frame 2 is fixedly arranged relative to the base 1, and has good stability in use.

[0048] like Figures 4 to 8 As shown in the figure, the following description is made by taking the example that the connecting shaft 1031 is arranged on the base 1, the connecting groove 2021 is arranged on the mounting frame 2, the multiple protrusions 1032 are arranged on the outer peripheral wall of the connecting shaft 1031, and the multiple grooves 2022 are arranged on the inner peripheral wall of the connecting groove 2021.

[0049] As a rotation example of a mounting frame 2, a plurality of protrusions 1032 are respectively inserted into corresponding grooves 2022. When the mounting frame 2 is driven to rotate by external force, the protrusions 1032 can be respectively rotated out of the initial grooves 2022 and rotated into the next grooves 2022 in turn until the mounting frame 2 is rotated to a preset position and the position of the mounting hole 201 reaches the preset mounting position.

[0050] As a preferred embodiment, the outer peripheral surface of each protrusion 1032 is an arc surface; a guide surface 2023 for guiding the protrusion 1032 to rotate into or out of the groove 2022 is provided between two adjacent grooves 2022. The outer peripheral surface of the protrusion 1032 is set as an arc surface, and the guide surface 2023 is provided, which is conducive to the protrusion 1032 rotating into or out of the groove 2022, thereby having good adjustment flexibility. In addition, to ensure the rotation effect of the mounting frame 2, a gap is formed between the two sides of the protrusion 1032 located in the groove 2022 and the two side walls of the groove 2022.

[0051] As another example of the rotation of the mounting frame 2, the mounting frame 2 can be detached from the base 1, and then the mounting frame 2 is rotated to a preset angle, and then the mounting frame 2 is suspended on the base 1 by inserting each protrusion 1032 in the corresponding groove 2022 at this position, and the mounting frame 2 can be kept at this position through the cooperation of the protrusion 1032 and the groove 2022, and will not rotate relative to the base 1. This rotation scheme of the mounting frame 2 has the advantages of simple operation and easy implementation.

[0052] like Figures 5 to 8 As shown in , a first fixing hole is provided on the base 1, and a first seat body 103 is installed in the first fixing hole through interference, and a connecting shaft 1031 is provided on the first seat body 103, for example, the connecting shaft 1031 can be integrally formed with the first seat body 103. A second fixing hole is provided on the mounting frame 2, and a second seat body 202 is installed in the second fixing hole through interference, and a connecting groove 2021 is provided on the second seat body 202. By arranging the connecting shaft 1031 on the first seat body 103 and the connecting groove 2021 on the second seat body 202, it is convenient to arrange the connecting shaft 1031, the connecting groove 2021 and the hovering part, and it is easy to process and arrange the implementation. It should be noted that the solution that the connecting shaft 1031 is arranged on the second seat body 202 and the connecting groove 2021 is arranged on the first seat body 103 is also feasible.

[0053] In order to improve the installation effect of the first base body 103 and the second base body 202, the Figure 4 , Figure 5 and Figure 7 As shown in the figure, a first flange 1033 protruding radially outward is provided on the side of the first seat body 103 away from the mounting portion 102, and a second flange 2024 protruding radially outward is provided on the side of the second seat body 202 away from the mounting frame 2. In the process of the first seat body 103 and the second seat body 202 being pressed into the first fixing hole and the second fixing hole respectively, the first seat body 103 can be confirmed to be installed in place on the mounting portion 102 by the abutment of the first flange 1033 and the mounting portion 102. The second seat body 202 can be confirmed to be installed in place on the mounting frame 2 by the abutment of the second flange 2024 and the mounting frame 2. In addition, the first flange 1033 and the second flange 2024 have simple structures, are easy to process and form, and have a good limiting effect.

[0054] In this embodiment, the first base body 103 and the second base body 202 are provided to facilitate replacement and maintenance of the hovering part, and also facilitate processing and molding, thereby reducing production and maintenance costs. Of course, it is also feasible to directly mold the connecting shaft 1031 and the connecting groove 2021 on the base 1 and the mounting frame 2 respectively.

[0055] In addition, in this embodiment, a magnetic attraction portion is provided between the base 1 and the mounting frame 2, and the magnetic attraction portion adsorbs the mounting frame 2 at a preset position on the base 1. This arrangement is conducive to preventing the mounting frame 2 from falling off the base 1, thereby improving the use stability of the mounting frame 2. Figure 5 and Figure 7 As shown in , the magnetic attraction portion includes a magnetic attraction block 1034 disposed on one of the base 1 and the mounting frame 2, and a matching block 2025 disposed on the other of the two and magnetically matched with the magnetic attraction block 1034.

[0056] As a preferred example, Figure 7 and Figure 8 As shown in the figure, the magnetic block 1034 is embedded in the end surface of the connecting shaft 1031, and the matching block 2025 is embedded in the bottom of the groove 2022. Such a configuration is not only conducive to meeting the rotation requirements of the mounting frame 2, but also can prevent the mounting frame 2 from falling out, and the magnetic block 1034 and the matching block 2025 have simple structures and are easy to arrange and implement. The magnetic block 1034 in this embodiment is a magnet, and the matching block 2025 is an iron block that can be attracted by a magnet.

[0057] The mounting structure in this embodiment, by rotating the mounting frame 2 and keeping the mounting frame 2 at a preset position with the help of the suspension part, is conducive to adjusting the height and position of the mounting part on the mounting frame 2 according to different needs, so as to meet the requirements of the copper bus or wire harness direction. Compared with the traditional bracket, it is conducive to improving the versatility of the mounting structure in the battery pack, so as to save the manufacturing cost of the battery pack. In addition, the mounting structure is conducive to making the structure in the battery pack more neat and beautiful, and is also conducive to improving the utilization rate of the space in the pack, and has a good promotion significance.
