[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] See Figures 1 to 6 This embodiment provides a wire harness protection structure, including a protective member 10 and a fastener 20. The protective member 10 extends along the X direction, and a positioning groove 101 is recessed along the Z direction on the protective member 10. Multiple positioning grooves 101 are spaced apart along the X direction. The bottom wall of the positioning groove 101 is provided with a mounting hole 102. A positioning opening 103 is opened on one side of the protective member 10 along the Y direction, avoiding the positioning groove 101. Multiple positioning openings 103 are spaced apart along the X direction and penetrate the protective member 10 along the Z direction for positioning the wire harness. The fastener 20 is disposed in the positioning groove 101 and is detachably connected to the mounting hole 102. The fastener 20 has a wire-passing hole 201 for passing the wire harness through. In this embodiment, the X direction is the length direction of the protective member 10, the Y direction is the width direction of the protective member 10, and the Z direction is the height direction of the protective member 10.

[0050] The protective component 10 extends along the X direction to guide the wire harness. The mounting hole 102 on the protective component 10 is used to install the fastener 20. The positioning groove 101 provides clearance for the fastener 20. The wire-passing hole 201 of the fastener 20 is used to pass the wire harness through, limiting and protecting it. The positioning port 103 on the protective component 10, which avoids the positioning groove 101, is used to position the wire harness. The fastener 20 is detachably connected to the mounting hole 102, facilitating wire harness installation and reducing wire harness movement and friction caused by vibration. When a wire harness malfunctions and needs repair or replacement, the entire protective structure does not need to be disassembled; only the corresponding fastener 20 needs to be removed to operate on the target wire harness, significantly reducing the time cost and operational difficulty of later maintenance. The cooperation between the fastener 20 and the protective component 10 ensures a neat and orderly arrangement of the wire harness, effectively alleviating wire harness tangling, twisting, and friction, thereby reducing assembly difficulty and improving assembly reliability. The protective component 10 and fastener 20 have a simple structure, are easy to assemble, occupy little space, and reduce costs.

[0051] The number of positioning grooves 101 and positioning openings 103 provided on the protective component 10 is not limited here. In some embodiments, at least some of the positioning openings 103 are located between two adjacent positioning grooves 101 to make full use of space and ensure structural compactness. Since there are multiple positioning grooves 101, no positioning opening 103 may be provided between two adjacent positioning grooves 101, or one positioning opening 103 may be provided, or two or more positioning openings 103 may be provided.

[0052] like Figure 4 As shown, in some embodiments, at least a portion of the positioning opening 103 is located on one side edge of the positioning groove 101 along the X direction. The positioning opening 103 is formed at the edge of the positioning groove 101 and does not interfere with the positioning groove 101's reception and positioning of the fastener 20. In some embodiments, at least a portion of the positioning opening 103 is located on the side of the positioning groove 101 at the outermost edge, close to the edge of the protective member 10.

[0053] The shape of the positioning groove 101 can be set according to actual needs. For example, the positioning groove 101 is cylindrical or cuboid. The positioning groove 101 has a bottom wall and side walls. The mounting hole 102 is provided in the bottom wall, and the side walls serve to protect the fasteners 20 inside the positioning groove 101. When the positioning groove 101 is cylindrical, the side walls of the positioning groove 101 are annular; when the positioning groove 101 is cuboid, the side walls of the positioning groove 101 are flat. The positioning groove 101 can have one side wall, two side walls, three side walls, or four side walls.

[0054] For example, at least a portion of the positioning groove 101 extends through at least one side of the protective member 10 along the Y direction, facilitating manufacturing and installation of the fastener 20. For example, at least a portion of the positioning groove 101 extends through both sides of the protective member 10 along the Y direction, and the positioning groove 101 has two opposing sidewalls, which are spaced apart along the X direction.

[0055] The mounting hole 102 can penetrate the protective member 10 along the Z direction, which facilitates processing and production. The mounting hole 102 can also be set as a blind hole, as long as it can be connected to the fastener 20. For example, the mounting hole 102 penetrates the protective member 10 along the Z direction, and part of the fastener 20 passes through the mounting hole 102 to engage with the protective member 10, which facilitates processing and production.

[0056] Exemplarily, the fastener 20 includes a fastening portion 21 and a connecting portion 22. The fastening portion 21 passes through the mounting hole 102 to engage with the protective member 10. One end of the connecting portion 22 is fixedly disposed on the fastening portion 21, and the other end of the connecting portion 22 is detachably connected to the fastening portion 21 to form a wire-passing hole 201. Through the cooperation of the fastening portion 21 and the connecting portion 22, the fastening portion 21 is used to connect the fastener 20 to the protective member 10, and the connecting portion 22 facilitates the threading of the wire harness by forming the wire-passing hole 201. During installation, the fastener 20 is placed in the positioning groove 101, the fastening portion 21 is inserted into the mounting hole 102 so that the fastening portion 21 engages with the mounting hole 102, the wire harness to be positioned is placed at the position of the connecting portion 22, and the free end of the connecting portion 22 is connected to the fastening portion 21 to position the wire harness.

[0057] The fastening part 21 and the connecting part 22 can be configured with different hardnesses. For example, the connecting part 22 can be made of a flexible strip, and the enclosure size can be flexibly adjusted according to the actual diameter of the wire harness to facilitate fixing and connection. In some embodiments, the fastening part 21 includes a support post and a plurality of elastic protrusions provided on the support post, which are inserted into the mounting hole 102 by means of the elasticity of the elastic protrusions. Exemplarily, the end of the support post has a tapered tip, which greatly reduces the difficulty of alignment when inserting into the mounting hole 102 and makes it easier to insert into the mounting hole 102. In some embodiments, the fastening part 21 includes a claw, which is inserted into the mounting hole 102 by means of the elasticity of the claw. In some embodiments, the connecting part 22 includes a strip body with locking teeth. The end of the connecting part 22 can pass through a locking hole on the fastening part 21, and the connecting part 22 is fixed by means of the locking teeth engaging with the locking hole. Exemplarily, the locking teeth are one-way ratchet teeth to prevent the connecting part 22 from disengaging from the locking hole under vibration.

[0058] While the fastening part 21 is engaged with the protective part 10, adhesive can be applied between the fastening part 21 and the protective part 10 to improve the stability of the fastener 20.

[0059] For example, the protective member 10 includes a first protective plate 11 and a second protective plate 12. A positioning groove 101 and a positioning opening 103 are both provided on the first protective plate 11. The second protective plate 12 is bent and connected to the first protective plate 11. An avoidance opening 121 is provided on the side of the second protective plate 12 away from the first protective plate 11 along the Z-direction. By providing the first protective plate 11 and the second protective plate 12, it is convenient to set the required installation or avoidance structure in different orientations. The positioning groove 101 and the positioning opening 103 are provided on the first protective plate 11, and the avoidance opening 121 is provided on the second protective plate 12 to avoid mutual interference. The required component can pass through the avoidance opening 121, so that the protective member 10 can protect the component.

[0060] The second protective plate 12 is bent and connected to the first protective plate 11, supporting each other to increase structural strength. The included angle between the second protective plate 12 and the first protective plate 11 can be set according to actual needs. For example, the included angle between the second protective plate 12 and the first protective plate 11 is 60 degrees to 120 degrees. For example, the second protective plate 12 is perpendicular to the first protective plate 11. The second protective plate 12 and the first protective plate 11 can be connected in an L-shape or a T-shape. Reinforcing ribs can be provided between the first protective plate 11 and the second protective plate 12 to increase structural strength.

[0061] For example, the first protective plate 11 has a first surface 111 and a second surface 112 disposed opposite to each other along the Z direction. A portion of the first surface 111 is recessed to form a positioning groove 101. The second protective plate 12 is disposed on the second surface 112 and perpendicular to the first protective plate 11. The second protective plate 12 can be disposed at the edge of the second surface 112 or at the middle position of the second surface 112. The second protective plate 12 avoids the positioning groove 101 so that the positioning groove 101 penetrates the protective member 10 along the Y direction, providing a larger space for the installation of the fastener 20.

[0062] For example, the second protective plate 12 is disposed on the side of the first protective plate 11 away from the positioning opening 103 along the Y direction, that is, the second protective plate 12 and the first protective plate 11 are connected in an L-shaped structure. The length direction of the second protective plate 12 is along the X direction, the width direction of the second protective plate 12 is along the Z direction, and the thickness direction of the second protective plate 12 is along the Y direction.

[0063] A clearance opening 121 is provided on the second protective plate 12, and the position of the clearance opening 121 on the second protective plate 12 can be determined as needed. For example, along the X direction, the clearance opening 121 is located on the side of the outermost positioning groove 101 near the edge of the protective member 10. Along the Z direction, the clearance opening 121 is located on the side of the second protective plate 12 away from the first protective plate 11. Along the Y direction, the clearance opening 121 penetrates through the second protective plate 12.

[0064] The protective component 10 also includes two opposing third protective plates 13. The two third protective plates 13 are respectively located at both ends of the first protective plate 11 along the X direction and connected to the second protective plate 12. The first protective plate 11, the second protective plate 12, and the third protective plate 13 form a protective cavity. The positioning groove 101 is recessed into the protective cavity. Both the positioning opening 103 and the clearance opening 121 communicate with the protective cavity. Therefore, the wire harness passing through the positioning opening 103 is at least partially located within the protective cavity. The protective cavity can isolate external interference from the X, Y, and Z directions, not only blocking the intrusion of dust, moisture, and other impurities, but also buffering external impacts to prevent direct force damage to the wire harness, thus providing protection. By including the first protective plate 11, the second protective plate 12, and the third protective plate 13 in the protective component 10, the structure is simple and easy to manufacture.

[0065] Along the Z-direction, the depth of the positioning groove 101 is less than or equal to the height of the protective cavity. By recessing the positioning groove 101 in the protective member 10, a portion of the fastener 20 can be accommodated. After the fastener 20 is connected to the mounting hole 102, a portion of the fastener 20 is located within the positioning groove 101, while a portion of the fastener 20 protrudes along the Z-direction from one side of the protective member 10 where the positioning groove 101 is located, facilitating the connection of the wire harness. By setting the depth of the positioning groove 101 to be less than or equal to the height of the protective cavity, sufficient space is ensured for the fastener 20, while preventing the positioning groove 101 from protruding from the other side of the protective member 10 in the Z-direction, thus avoiding interference with other components.

[0066] See Figures 7 to 12 This embodiment also provides a battery pack, including a battery housing 100, the aforementioned wiring harness protection structure, and an assembly wiring harness 200. The wiring harness protection structure is disposed within the battery housing 100. The assembly wiring harness 200 is disposed within the battery housing 100 and includes multiple branch wiring harnesses 210. The multiple branch wiring harnesses 210 are respectively inserted through positioning openings 103 and extend along the X direction, converging at the assembly wiring harness 200 before being inserted along the X direction through at least one through-hole 201. The protective component 10 guides the assembly wiring harness 200 to extend along the X direction, thus guiding the assembly wiring harness 200. The branch wiring harnesses 210 are located within the positioning openings 103, achieving wiring harness diversion, preventing multiple branch wiring harnesses 210 from merging and clogging together, and facilitating the installation of branch wiring harnesses 210, improving installation efficiency. After installation, the assembly wiring harness 200 and branch wiring harnesses 210 can be neatly and orderly arranged, effectively alleviating wiring harness tangling, twisting, and friction. The protective component 10 provides support for the wire harness, preventing it from falling off under vibration. Meanwhile, the separate and orderly arrangement of the positioning port 103 and the wire-passing hole 201 avoids wire harness accumulation caused by bundling, increases the heat dissipation surface area of ​​a single wire harness, and reduces the risk of wire harness insulation aging.

[0067] Branch harness 210 branches off from the main harness 200. Branch harness 210 connects to various internal components of the battery pack, such as the BMU, CMU, and BDSB. Therefore, the diameter of branch harness 210 is smaller than that of the main harness 200. The size of the positioning opening 103 can be determined based on the diameter of branch harness 210, allowing it to be secured within the opening for initial fixation. The positioning opening 103 positions and limits the branch harness 210, preventing it from swinging freely during transport and use. It also prevents the positioning opening 103 from becoming too large, which would reduce the structural strength of the protective component 10. Furthermore, by rationally setting the size of each positioning opening 103, space is fully utilized.

[0068] The battery pack also includes an electrical compartment 300, which is disposed within the battery housing 100. A protective member 10 is disposed on one side of the electrical compartment 300 along the Z-direction. At least a portion of the branch wiring harness 210 passes through the inlet 310 of the electrical compartment 300, and the protective member 10 blocks the inlet 310. By engaging the protective member 10 with the electrical compartment 300, it acts as a sealant, preventing the expanding foam from spreading from the inlet 310 into the electrical compartment 300 during the potting of the battery pack. Since the depth of the positioning groove 101 along the Z-direction is less than or equal to the height of the protective cavity, the recessed positioning groove 101 will not block the inlet 310.

[0069] For example, the electrical compartment 300 is located on one side of the battery housing 100 along the Y direction, and the cable inlet 310 is located on one side of the electrical compartment 300 along the Z direction. A battery module is disposed inside the battery housing 100, which also includes a bottom protective plate and a cover. Along the Z direction, the bottom protective plate is located at the bottom of the battery module, and the cover is located at the top of the battery module. For example, the cable inlet 310 is located at the top of the electrical compartment 300, and the protective member 10 is also located at the top of the electrical compartment 300; that is, both the cable inlet 310 and the protective member 10 are located on the side of the electrical compartment 300 closest to the cover. Branch wire harnesses 210 on the protective member 10 pass through the cable inlet 310 into the electrical compartment 300. The cable inlet 310 can be configured as a long strip extending along the X direction, facilitating the passage of multiple branch wire harnesses 210 within a single cable inlet 310.

[0070] The protective component 10 includes a first protective plate 11, a second protective plate 12, and a third protective plate 13 to form a protective cavity. The first protective plate 11 and the third protective plate 13 abut against the side wall of the battery housing 100 along the Y direction, and the second protective plate 12 and the third protective plate 13 abut against the top wall of the electrical compartment 300 along the Z direction. This arrangement ensures that the protective cavity of the protective component 10 communicates with the inlet 310 of the electrical compartment 300, and the first protective plate 11, the second protective plate 12, and the third protective plate 13 of the protective component 10 cooperate to prevent adhesive from entering the protective cavity through the edges of the protective component 10 by abutting against the side wall of the battery housing 100 and the top wall of the electrical compartment 300.

[0071] For example, the side wall of the battery box 100 is flat, and the first protective plate 11 and the third protective plate 13 are flush with one side along the Y direction so as to fully contact the side wall of the battery box 100; the top wall of the electrical compartment 300 is flat, and the second protective plate 12 and the third protective plate 13 are flush with one side along the Z direction so as to fully contact the top wall of the electrical compartment 300.

[0072] The assembly wiring harness 200 is located on the side of the first protective plate 11 away from the electrical compartment 300 and runs along the first protective plate 11. The branch wiring harness 210 is housed in the protective cavity. The first protective plate 11 guides the assembly wiring harness 200, and the protective cavity protects the branch wiring harness 210.

[0073] The battery pack also includes a sealing gasket 400, which is disposed between the electrical compartment 300 and the protective component 10. By providing the sealing gasket 400, the gap between the protective component 10 and the electrical compartment 300 is sealed, further preventing the foam from entering the protective cavity during potting, thereby preventing the foam from spreading from the inlet 310 into the electrical compartment 300.

[0074] For example, the battery pack also includes copper busbars 500, which pass through the clearance opening 121. The protective member 10 protects the copper busbars 500 and provides insulation to enhance safety. Part of the copper busbars 500 are located inside the electrical compartment 300, and part are located outside the electrical compartment 300. The copper busbars 500 located outside the electrical compartment 300 pass through the protective cavity and the clearance opening 121. The shape of the clearance opening 121 can be configured to match the shape of the copper busbars 500. The number of clearance openings 121 can be set according to actual needs, and the clearance openings 121 can accommodate the required components as needed.

[0075] The length, width, and height of the protective component 10 can be set according to actual needs, reducing space occupation, achieving internal clearance within the package, and simultaneously serving functions such as installation, positioning, limiting, and protection. For example, the protective component 10 is a plastic part, which facilitates one-piece molding, has a simple process and high integration, provides insulation, and allows for control of the length of the protective component 10 along the X direction as needed. The protective component 10 can be fixed to the electrical compartment 300 or the battery box 100 using methods such as adhesive bonding or riveting, resulting in low cost and high installation efficiency. The protective component 10 provides insulation protection, improving the assembly efficiency and safety of the entire package.

[0076] This embodiment also provides an electrical device, including the battery pack described above. The electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0077] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
