[0001] The utility model relates to the technical field of battery packs, and in particular to a wiring harness bracket structure and a battery pack. Background Art

[0002] The battery pack is the most important power supply component of an electric vehicle. The wiring harness serves as a transmission carrier for battery pack signals and currents, connecting the various parts of the battery pack together. Therefore, the installation and fixation method of the wiring harness in the battery pack is very important.

[0003] Most of the methods for fixing the wiring harness in related technologies are to set a bracket on the battery pack. Generally, the bracket and the battery pack are mostly connected by welding.

However, setting the bracket by welding is not conducive to the assembly and transportation of the battery pack. The method of fixing the bracket to the outside of the battery pack by bolts and other connectors requires multiple connectors to achieve the positioning connection of the bracket, and the assembly efficiency is low.

[0034] The utility model provides a wire harness bracket structure.

[0035] Reference Figures 1 to 7 , Figure 1 This is a structural schematic diagram of an embodiment of the wiring harness bracket structure of the utility model; Figure 2 This is a schematic diagram of the structure of a bracket in an embodiment of the wiring harness bracket structure of the utility model; Figure 3 This is a schematic structural diagram of a bracket in another embodiment of the wiring harness bracket structure of the utility model; Figure 4 It is a partial structural schematic diagram of a beam body in an embodiment of the wiring harness support structure of the utility model; Figure 5 It is a cross-sectional structural schematic diagram of an embodiment of the wiring harness support structure of the utility model; Figure 6 This is a schematic structural diagram of an embodiment of a battery pack of the utility model; Figure 7 It is a structural schematic diagram of another embodiment of the battery pack of the utility model.

[0036] In the embodiment of the present utility model, the wiring harness support structure 100; Figures 1 to 5 As shown, including:

[0037] Beam 60;

[0038] A bracket 10, the bracket 10 is mounted on the beam body 60 through a connector 14 and is used to fix the wiring harness;

[0039] The bracket 10 is provided with a limiting portion 30 , and the limiting portion 30 passes through the beam body 60 .

[0040] It should be noted that the beam body 60 is the longitudinal beam of the battery pack case. A high-voltage wire harness is generally arranged on the front side of the battery pack case. Therefore, the high-voltage wire harness needs to be fixed to ensure the stability of the connection of the high-voltage wire harness. Therefore, a fixing bracket for fixing the high-voltage wire harness needs to be provided on the outer side of the battery pack case. Generally, the fixing bracket is mostly provided on the longitudinal beam of the battery pack case.

[0041] It is understandable that if Figure 6 to Figure 7 As shown, the side of the beam body 60 exposed from the battery pack case is defined as the installation surface of the bracket 10. Since the high-voltage wire harness is arranged on one side of the battery pack case, the bracket 10 is arranged on the side of the beam body 60 close to the high-voltage wire harness, so that the bracket 10 can support the high-voltage wire harness and improve the stability of the high-voltage wire harness.

[0042] It should be noted that, generally, the fixing bracket is mostly connected to the battery pack case by welding, and the fixing bracket externally arranged on the battery pack case will affect the convenience and efficiency of packaging during the packaging of the battery pack case.

[0043] It can be understood that the bracket 10 is detachably connected to the side of the beam body 60 through the connecting piece 14. When the battery pack case is packaged, the bracket 10 is disassembled and packaged separately from the battery pack case to improve the packaging efficiency of the battery pack case. When the bracket 10 and the longitudinal beam are assembled, the bracket 10 and the longitudinal beam are connected together through the connecting piece 14 to fix the high-voltage wiring harness.

[0044] In order to ensure the accuracy of the connection between the bracket 10 and the beam body 60, a limiting portion 30 is provided on the bracket 10. During the assembly of the bracket 10, the limiting portion 30 is passed through the beam body 60 and cooperates with the connecting piece 14 to accurately position and fix the bracket 10 on the side of the beam body 60, which is beneficial to improve the assembly efficiency of the bracket 10 while improving the accuracy of the assembly of the bracket 10.

[0045] It is understandable that the number of the connecting member 14 is one. Since the limiting portion 30 is disposed through the beam body 60, only a single connecting member 14 is needed to fix the bracket 10 on the beam body 60, thereby reducing the assembly cost of the bracket 10 and improving the assembly efficiency.

[0046] The technical solution of the utility model fixes the wiring harness through the bracket 10, and the bracket 10 is detachably connected to the side of the beam body 60 through the connecting piece 14 to improve the assembly efficiency of the bracket 10, and when the beam body is packaged, the bracket 10 is disassembled to improve the packaging efficiency and reduce the difficulty of packaging, and by setting the limiting portion 30, during the assembly of the bracket 10, the limiting portion 30 is penetrated into the beam body 60, and cooperates with the connecting piece 14 to achieve the positioning of the bracket 10 on the beam body 60, thereby ensuring the accuracy of assembly, and at the same time, only a single connecting piece 14 is needed to fix the bracket, thereby improving the efficiency of assembly and reducing the cost of assembly.

[0047] In order to facilitate the penetration of the limiting portion 30 to achieve the assembly and positioning of the bracket 10 , a positioning hole 70 is provided on the beam body 60 , and the limiting portion 30 is penetrated through the positioning hole 70 .

[0048] It is understandable that if Figures 1 to 5 As shown, the positioning hole is provided on the beam body 60 , and when the bracket 10 is assembled, the limiting portion 30 is inserted into the positioning hole to limit the bracket 10 in a single direction of the beam body 60 , and cooperates with the connecting piece 14 to realize the positioning and fixation of the bracket 10 on the beam body 60 .

[0049] It is understandable that the limiting portion 30 can be limitedly positioned on the beam body 60 , and a positioning groove facing the bracket 10 can be opened on the beam body 60 , and part of the limiting portion 30 is inserted into the positioning groove to ensure that the bracket 10 is positioned.

[0050] Preferably, the bracket 10 includes a mounting portion 11 and a limiting portion 30 , the mounting portion 11 is disposed on a side of the beam body 60 , the limiting portion 30 is disposed on a side edge of the mounting portion 11 , and the limiting portion 30 and the mounting portion 11 are disposed at an angle.

[0051] It can be understood that in order to ensure the stability of the assembly of the bracket 10 on the beam body 60, the mounting portion 11 is attached to the side of the beam body 60, and then when the bracket 10 is fixed to the side of the beam body 60 by the connecting member 14, the mounting portion 11 is tightly attached to the beam body 60, thereby avoiding relative movement between the bracket 10 and the beam body 60 and ensuring the stability of the connection.

[0052] like Figure 1 and Figure 5As shown, in order to ensure the convenience of assembly of the mounting portion 11 and to realize the positioning of the mounting portion 11 on the side of the beam body 60 through the limiting portion 30, the limiting portion 30 and the mounting portion 11 are arranged at an angle. During assembly, the limiting portion 30 is first inserted into the positioning hole 70, and then the mounting portion 11 is made to fit tightly against the side of the beam body 60.

[0053] Preferably, the angle between the limiting portion 30 and the mounting portion 11 is 90°.

[0054] In order to make the limiting portion 30 and the mounting portion 11 integral, the limiting portion 30 is bent and disposed on one side edge of the mounting portion 11 .

[0055] It is understandable that if Figures 2 to 3 As shown, the limiting portion 30 is bent and arranged on the side of the mounting portion 11, so that the limiting portion 30 and the mounting portion 11 are integrated, eliminating the connection process of the limiting portion 30 and the mounting portion 11.

[0056] It should be noted that the limiting portion 30 is located at the edge of the mounting portion 11 and at the edge where the mounting portion 11 contacts the beam body 60 , so that the limiting portion 30 can be inserted into the beam body 60 to achieve limited positioning of the mounting portion 11 .

[0057] It can be understood that, in one embodiment, the limiting portion 30 is arranged on the edge of the mounting portion 11 that is not in contact with the beam body 60, and when the bracket 10 is matched with the beam body 60, the limiting portion 30 abuts against the side of the beam body 60. At this time, the limiting portion 30 can also realize the positioning of the bracket 10 in one direction of the beam body 60.

[0058] In order to better organize the wiring harness, such as Figure 5 As shown, part of the mounting portion 11 is attached to the side surface of the beam body 60 , and part of the mounting portion 11 is suspended in the air.

[0059] It is understandable that the wire harness disposed on the front side of the battery pack case is fixed to the suspended portion of the mounting portion 11 to avoid bending the wire harness when it is constrained by the wire harness clamp 90, so as to ensure that the wire harness is neatly arranged.

[0060] It can be understood that when the mounting portion 11 is partially attached to the side of the beam body 60, the limiting portion 30 passes through the beam body 60 and the connecting member 14 connects the mounting portion 11 and the beam body 60, the mounting portion 11 is tightly attached to the side of the beam body 60 to avoid a gap between the mounting portion 11 and the side of the beam body 60 to affect the stability of the installation of the bracket 10.

[0061] In order to facilitate the penetration and connection of the connecting member 14 , a mounting hole 80 is provided on the side of the beam body 60 , and the mounting portion 11 is provided with a through hole 20 . The connecting member 14 penetrates the through hole 20 and the mounting hole 80 and is connected to the beam body 60 .

[0062] It can be understood that the connecting member 14 is a bolt.

[0063] It can be understood that when the limiting portion 30 is passed through the beam body 60 to achieve positioning between the mounting portion 11 and the beam body 60, the mounting hole 80 is aligned with the through hole 20 to facilitate the passing of the connecting member 14 to achieve connection between the beam body 60 and the mounting portion 11.

[0064] It can be understood that the beam body 60 and the bracket 10 are connected by the single connecting member 14, but with the cooperation of the limiting portion 30, the bracket 10 can also be stably fixed to the beam body 60 to ensure the stability of the wire harness constraint.

[0065] In this embodiment, the bracket 10 is connected to the beam body 60 via the connecting piece 14, and the connecting piece 14 is detachably connected. During packaging and transportation, the bracket 10 is removed from the beam body 60 to avoid bumping or damage to the battery pack due to the bracket 10 protruding from the battery pack case. During assembly, the bracket 10 is directly fixed to the side of the beam body 60 via the connecting piece 14 in cooperation with the limiting portion 30, thereby improving the installation efficiency of the bracket 10.

[0066] Optionally, a fixing portion 13 is provided on the edge of the suspended mounting portion 11 , a wire harness clamp 90 is provided on the fixing portion 13 , and the wire harness clamp 90 fixes the wire harness.

[0067] Specifically, Figures 1 to 3 As shown, the fixing portion 13 is provided at a bent edge of the mounting portion 11 , and the fixing portion 13 is provided at a suspended portion of the mounting portion 11 .

[0068] It can be understood that the fixing portion 13 is bent and disposed on the mounting portion 11 , and the fixing portion 13 is integrated with the mounting portion 11 to facilitate processing of the fixing portion 13 .

[0069] Specifically, Figures 2 to 3 As shown, a connection hole 50 is provided on the fixing portion 13 , the wire harness clamp 90 wraps the restrained wire harness, a bolt passes through the connection hole 50 , and the wire harness clamp 90 is clamped between the fixing portion 13 and the bolt.

[0070] It is understandable that the wire harness clamp 90 is fixed to the side of the fixing portion 13 by bolts so as to fix the wire harness on the bracket 10 .

[0071] It should be noted that the fixing portion 13 and the mounting portion 11 are arranged at an angle, and the fixing portion 13 is bent and coupled to the wiring harness clamp 90 so that the fixing portion 13 can better cooperate with the wiring harness clamp 90 to constrain the wiring harness, thereby ensuring that the wiring harness is neat when being constrained and fixed.

[0072] Cooperating with the suspended mounting portion 13, the bent fixing portion 13 can better restrain the wiring harness arranged on the front side of the battery pack body to ensure the neatness of the wiring harness after restraint.

[0073] In order to improve the structural strength of the bracket 10 , a reinforcing portion 12 is further provided at the edge of the mounting portion 11 , and the reinforcing portion 12 is arranged at an angle to the mounting portion 11 .

[0074] Specifically, Figures 1 to 3 As shown, the reinforcing portion 12 is disposed at the edge of the mounting portion 11 , and the reinforcing portion 12 is bent and disposed at the edge of the mounting portion 11 .

[0075] It is understandable that the reinforcing portion 12 is provided by bending the edge of the mounting portion 11 to increase the structural bending strength of the bracket 10, thereby preventing the bracket 10 from bending under force when the battery pack box is subjected to external force and affecting the restraint effect on the wiring harness.

[0076] It can be understood that the mounting portion 11, the reinforcing portion 12, the fixing portion 13 and the limiting portion 30 are all sheet metal parts. By providing the reinforcing portion 12 on the side of the mounting portion 11, the structural strength of the bracket 10 is improved and the weight of the bracket 10 is reduced.

[0077] It should be noted that one or more reinforcement parts 12 may be provided on the edge of the mounting part 11 .

[0078] In order to ensure the connection between the connecting piece 14 and the wiring harness clamp 90 , a first nut 41 is provided on the side of the fixing portion 13 close to the mounting portion 11 for connecting the wiring harness clamp 90 , and a second nut 42 is provided on the side of the beam body 60 away from the mounting portion 11 for connecting the connecting piece 14 .

[0079] It should be noted that the first nut 41 is welded to the side of the fixing portion 13 close to the mounting portion 11 , and the second nut 42 is welded to the side of the beam body away from the mounting portion 11 .

[0080] It should be noted that the nut hole of the first nut 41 is connected to the connecting hole 50 , and the nut hole of the second nut 42 is connected to the through hole 20 and the mounting hole 80 .

[0081] It is understandable that the connecting member 14 passes through the through hole 20 , the mounting hole 80 and the nut hole 42 of the second nut in sequence, and is connected to the second nut 42 , and the bracket 10 is installed or removed by rotating the connecting member 14 .

[0082] It can be understood that the bolt fixing the wiring harness clamp 90 on the fixing portion 13 passes through the connecting hole 50 and is connected to the first nut 41, so that the wiring harness clamp 90 can be detachably installed on the fixing portion 13, which is convenient for installing the wiring harness clamp 90 while agreeing on the wiring harness.

[0083] The utility model also proposes a battery pack, which includes the wiring harness support structure 100. The specific structure of the wiring harness support structure 100 refers to the above-mentioned embodiment. Since the battery pack adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0084] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
