[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0038] This application proposes a bracket structure. Figures 1 to 6 In some embodiments of the present application, as shown in the accompanying drawings, the Z direction is a first direction, the Y direction is a second direction, and the X direction is a third direction. The first direction and the second direction intersect, and both the first direction and the second direction are perpendicular to the third direction. The following description will be based on the first direction X, the second direction Y, and the third direction Z.

[0039] See also Figures 1 to 2 In some embodiments of the present application, the mounting bracket 1 includes a first mounting end 1A in a first direction Z, and the first mounting end 1A is configured to mount a copper bus 2; wherein at least one side of the mounting bracket 1 in a second direction Y is configured to mount a wiring harness 3.

[0040] The mounting bracket 1 also includes a second mounting end 1B arranged opposite to the first mounting end 1A in the first direction Z, and the second mounting end 1B is configured to be connected to the battery box; wherein, the wiring harness 3 installed on one side of the mounting bracket 1 in the second direction Y is located between the first mounting end 1A and the second mounting end 1B.

[0041] In the technical solution of the present application, the copper busbar 2 is installed on the first mounting end 1A of the mounting bracket 1, and the wiring harness 3 is installed on one side of the mounting bracket 1 in the second direction Y, so that the copper busbar 2 and the wiring harness 3 can be integrated and installed on the mounting bracket 1, thereby concentrating the arrangement of the wiring harness 3 and the copper busbar 2 in the battery pack to reduce the space occupied by the wiring harness 3 and the copper busbar 2 in the battery pack.

[0042] It can be understood that since the copper busbar 2 is arranged on the first mounting end 1A of the mounting bracket 1 in the first direction Z, the wiring harness 3 is located on one side of the mounting bracket 1 in the second direction Y, and is located between the first mounting end 1A and the second mounting end 1B, that is, the copper busbar 2 and the wiring harness 3 are arranged in sequence in the first direction Z, and the space size in the first direction Z in the battery pack can be effectively utilized, that is, the mounting bracket 1 can integrate the copper busbar 2 and the wiring harness 3 together in the first direction Z.

[0043] In one embodiment of the present application, the wiring harness 3 can be installed on one side of the mounting bracket 1 in the second direction Y; in another embodiment of the present application, the wiring harness 3 can be installed on both opposite sides of the mounting bracket 1 in the second direction Y.

[0044] Please refer again Figures 1 to 2 In some embodiments of the present application, wiring harnesses 3 can be installed on both sides of the mounting bracket 1 in the second direction Y. This arrangement allows more wiring harnesses 3 to be integrated and installed on the mounting bracket 1, and different wiring harnesses 3 can be installed on both sides of the mounting bracket 1 in the second direction Y according to the different positions of the wiring harnesses 3 in the battery pack.

[0045] In addition, there is no limitation on the relative fixing form between the wiring harness 3 and the mounting bracket 1 , which can be a snap connection or an adhesive connection.

[0046] See also Figures 2 to 3In some embodiments of the present application, the bracket structure further includes a limiting portion 4, which is arranged on one side of the mounting bracket 1 in the second direction Y and is connected to the mounting bracket 1; wherein, at least a portion of the limiting portion 4 is spaced apart from the mounting bracket 1 in the second direction Y; in this embodiment, at least a portion of the limiting portion 4 is spaced apart from the mounting bracket 1 in the second direction Y by a certain space, that is, the space between at least a portion of the limiting portion 4 and the mounting bracket 1 in the second direction Y can be used to accommodate the wiring harness 3, and the operator or operating tooling can install the wiring harness 3 between the limiting portion 4 and the mounting bracket 1, thereby achieving the fixation of the relative positions of the mounting bracket 1 and the wiring harness 3.

[0047] It can be understood that the limiting portion 4 can limit the wire harness 3 from being separated from the mounting bracket 1 in the second direction Y.

[0048] In addition, in some embodiments of the present application, the part where the limiting portion 4 is connected to the mounting bracket 1 is the first part, and the other part where the limiting portion and the mounting bracket 1 are spaced apart in the second direction Y is the second part. The first part is connected to the second part, and the first part is located on the side of the second part that is away from the first mounting end 1A in the first direction Z. This arrangement is because, under the action of gravity, the wiring harness 3 will move in the first direction Z in a direction away from the first mounting end 1A, and the first part is the part where the limiting portion 4 is connected to the mounting bracket 1, thereby stopping the movement of the wiring harness 3 in the first direction Z and preventing the wiring harness 3 from separating from the mounting bracket 1.

[0049] In some embodiments of the present application, a mounting groove 5 is provided on one side of the mounting bracket 1 in the second direction Y, and the mounting groove 5 is configured to accommodate at least a portion of the wiring harness 3; such a configuration ensures that the bracket structure does not occupy too much space in the battery pack in the second direction Y.

[0050] Among them, the fixed size of the wiring harness 3 installed on one side of the mounting bracket 1 in the second direction Y is used for explanation. When the mounting bracket 1 is not provided with the mounting groove 5, the entire wiring harness 3 protrudes from the mounting bracket 1 in the second direction Y, so that the overall size of the limiting portion 4 and the mounting bracket 1 in the second direction Y is longer. The mounting groove 5 is provided on the mounting bracket 1, and part of the wiring harness 3 can be located in the mounting groove 5, that is, only part of the wiring harness 3 will protrude from the mounting bracket 1 in the second direction Y, so as to reduce the overall size of the limiting portion 4 and the mounting bracket 1 in the second direction Y, thereby reducing the size of the space occupied by the bracket structure in the battery pack in the second direction Y.

[0051] Likewise, since the mounting bracket 1 is provided with the mounting groove 5 , the overall size and weight of the mounting bracket 1 can also be reduced.

[0052] In some embodiments of the present application, the cross-section of the limiting portion 4 on the plane where the first direction Z and the second direction Y are located is arc-shaped; that is, when the wiring harness 3 is arranged between the limiting portion 4 and the mounting bracket 1, the shape of the side of the limiting portion 4 close to the wiring harness 3 matches the outer peripheral shape of the wiring harness 3, so that when the wiring harness 3 is installed between the limiting portion 4 and the mounting bracket 1, the space waste between the limiting portion 4 and the wiring harness 3 is reduced, so as to effectively utilize the space between the limiting portion 4 and the mounting bracket 1.

[0053] In some embodiments of the present application, the groove shape of the mounting groove 5 located on the mounting bracket 1 is also arranged in an arc shape, so that the groove wall shape of the mounting groove 5 matches the outer peripheral shape of the wiring harness 3, so that when the wiring harness 3 is installed between the limiting portion 4 and the mounting bracket 1, the space waste between the mounting bracket 1 and the wiring harness 3 is reduced, so as to effectively utilize the space between the limiting portion 4 and the mounting bracket 1.

[0054] In some embodiments of the present application, one end of the limiting portion 4 is connected to the mounting bracket 1, and the other end is spaced apart from the mounting bracket 1 to form an opening 6; that is, in this embodiment, the wiring harness 3 can enter between the limiting portion 4 and the mounting bracket 1 from the opening 6 to achieve the fixation of the wiring harness 3 on the bracket structure.

[0055] In some embodiments of the present application, the limiting portion 4 is elastic; wherein the size of the opening 6 in the second direction Y is smaller than the size of the wiring harness 3 in the second direction Y; that is, in this embodiment, when the wiring harness 3 is located between the limiting portion 4 and the mounting bracket 1 and is not subjected to external force, the size of the opening 6 is set so that the wiring harness 3 is not easy to fall out from between the limiting portion 4 and the mounting bracket 1, so as to ensure the stability of the installation of the wiring harness 3 on the bracket structure.

[0056] When the wiring harness 3 is installed on the bracket structure, since the limiting part 4 is elastic, it can be elastically deformed under the action of external force. At this time, the size of the opening 6 in the second direction Y increases, so that the wiring harness 3 can enter between the limiting part 4 and the mounting bracket 1.

[0057] There is no limitation on the fixing method of the mounting bracket 1 and the limiting portion 4. In one embodiment, the mounting bracket 1 and the limiting portion 4 can be integrally formed; in another embodiment of the present application, the mounting bracket 1 and the limiting portion 4 are independent components connected to each other by means of a snap connection, a fusion connection, or the like.

[0060] In some embodiments of the present application, the mounting bracket 1 is provided with a fixing groove 8 extending along the first direction Z on the first mounting end 1A; wherein, at least a portion of the fixing portion 72 is limited in the fixing groove 8; in this embodiment, the copper bus 2 can be fixed on the first mounting end 1A through the cooperation between the fixing groove 8 and the fixing portion 72.

[0061] Among them, the matching form of the fixing groove 8 and the fixing part 72 is not limited. In one embodiment of the present application, the fixing groove 8 can be a threaded groove, and the fixing part 72 is screwed into the fixing groove 8; in another embodiment of the present application, the fixing groove 8 can be a card slot, and a card protrusion is provided on the outer periphery of the fixing part 72, and the card protrusion on the outer periphery of the fixing part 72 is card-engaged with the fixing groove 8.

[0062] In some embodiments of the present application, the connecting portion 71 is a cable tie, which is used to tighten and limit the copper busbar 2, and the fixing portion 72 is provided on one side of the cable tie.

[0063] When the copper busbar 2 is fixed at the first mounting end 1A, the extension direction of the copper busbar 2 is not restricted; in one embodiment of the present application, the copper busbar 2 fixed at the first mounting end 1A extends in a plane perpendicular to the first direction Z; in another embodiment of the present application, the copper busbar 2 fixed at the first mounting end 1A extends in a plane perpendicular to the second direction Y and is vertically arranged on the first mounting end 1A.

[0065] In some embodiments of the present application, the copper busbar 2 is extended along the third direction X.

[0067] In some embodiments of the present application, the wire duct 9 can be used to install wires, signal wires, etc. whose size is smaller than that of the wire harness 3 located between the mounting bracket 1 and the limiting portion 4 .

[0068] In some embodiments of the present application, at least a portion of the mounting bracket 1 is hollowed out. That is, in this embodiment, the mounting bracket 1 is provided with at least one weight-reducing groove 14. The design of the weight-reducing groove 14 can reduce the weight of the mounting bracket 1 and also save consumable materials for the mounting bracket 1.

[0069] In some embodiments of the present application, the weight-reducing groove 14 is provided in the third direction X and passes through the mounting bracket 1 .
