[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0028] According to the inventors, when a vehicle is in motion, it is inevitably affected by external excitations (such as road conditions) and internal excitations (such as vibrations of the power system and body vibrations) in the operating environment. This causes the vehicle's motor wiring harness to be prone to shaking and pulling, which not only poses a risk of wire cutting but also exacerbates the wear and tear on the motor wiring harness, making it impossible to ensure the safety and reliability of the vehicle.

[0029] To address the insufficient protection of vehicle motor wiring harnesses in existing technologies, it is necessary to structurally improve or optimize existing technologies to ensure vehicle safety and reliability.

[0030] Example 1 Please see Figures 1 to 6 An embodiment of the first aspect of this utility model provides a motor wiring harness sheath. The motor wiring harness sheath 100 includes a sheath body 10 and a sheath fixing portion 11, wherein the sheath fixing portion 11 is formed on the outer surface of the sheath body 10 and is used to connect with the vehicle body to fix the motor wiring harness sheath 100 on the vehicle body. Preferably, the sheath fixing portion 11 is integrally formed with the sheath body 10. This helps to reduce problems such as gaps and mismatches that may occur during assembly.

[0031] For example, such as Figure 1 , Figure 2 and Figure 3As shown, the sheath body 10 includes a main line protection section 101 and at least one branch line protection section 102, wherein the branch line protection section 102 is connected to the main line protection section 101. Specifically, one end of the branch line protection section 102 is connected to the outer surface of the main line protection section 101, and the other end of the branch line protection section 102 extends in a direction away from the main line protection section 101. Preferably, the branch line protection section 102 and the main line protection section 101 are integrally formed. It should be noted that, in order to achieve the purpose of protecting the vehicle's motor wiring harness 1, the main line protection section 101 forms a main line receiving cavity 103, and the branch line protection section 102 forms a branch line receiving cavity 104, wherein the main line receiving cavity 103 is used to receive the main line of the vehicle's motor wiring harness 1, and the branch line receiving cavity 104 is used to receive the branch line branching from the main line, and one end of the branch line receiving cavity 104 is connected to the main line receiving cavity 103, and the other end of the branch line receiving cavity 104 extends in a direction away from the main line receiving cavity 103. Preferably, both the main line receiving cavity 103 and the branch line receiving cavity 104 are semi-enclosed structures, such as a U-shaped structure. This facilitates the installation of the main line and branch line of the motor wiring harness 1 within the main line protection section 101 and the branch line protection section 102, respectively, through the respective receiving spaces of the main line receiving cavity 103 and the branch line receiving cavity 104. Specifically, when the motor wiring harness sheath 100 is installed outside the motor wiring harness 1 of the vehicle, the main line of the motor wiring harness 1 is located in the main line receiving cavity 103, and the branch line of the motor wiring harness 1 is located in the branch line receiving cavity 104. The isolation of the motor wiring harness 1 by the motor wiring harness sheath 100 is beneficial for protecting the motor wiring harness 1 (e.g., preventing the motor wiring harness 1 from being cut due to forced vibration).

[0032] For example, please refer to the following: Figure 4 , Figure 5 To ensure that the layout of the motor wiring harness 1 conforms to the design requirements, the main protection section 101 includes a straight section 105 and a bent section 106. The bent section 106 is located at one end of the straight section 105 and bends away from the straight section 105. Specifically, viewed from the rear of the vehicle towards the front, the straight section 105 extends along the width of the vehicle, and the bent section 106 bends from one end of the straight section 105 towards the front of the vehicle (in the direction of the vehicle's front end). Furthermore, the length of the straight section 105 is greater than the length of the bent section 106. Preferably, the angle between the bent section 106 and the straight section 105 is an obtuse angle. This helps to prevent damage to the internal structure of the motor wiring harness 1 due to significant bending.

[0033] It is worth mentioning that the main line receiving cavity 103 passes through the straight section 105 and the bent section 106, one end of the branch line receiving cavity 104 is connected to the main line receiving cavity 103 on the straight section 105, and the other end of the branch line receiving cavity 104 extends in a direction away from the main line receiving cavity 103 on the straight section 105.

[0034] Furthermore, to ensure the arrangement path of each branch of the motor wiring harness 1, in some embodiments, the number of branch protection segments 102 is multiple. In this embodiment, there are five branch protection segments 102. Specifically, four of these five branch protection segments 102 are arranged at intervals along the axial direction of the straight segment 105 on one side of the straight segment 105, and the other branch protection segment 102 is arranged on the other side of the straight segment 105. By having each branch protection segment 102 correspond one-to-one with each branch of the motor wiring harness 1, it is convenient to protect each branch of the motor wiring harness 1. It should be noted that the included angle between each branch protection segment 102 and the straight segment 105 is related to the arrangement path of the corresponding branch in the motor wiring harness 1. That is, the included angle between the branch protection segment 102 and the straight segment 105 can be an acute angle, a right angle, or an obtuse angle, which is beneficial for matching the arrangement path requirements of each branch.

[0035] For example, such as Figure 1 , Figure 4 and Figure 5 As shown, to secure the motor wiring harness sheath 100 to the vehicle body, a sheath fixing hole 110 is provided on the sheath fixing part 11. The sheath fixing hole 110 is used to cooperate with fasteners to secure the motor wiring harness sheath 100 to the vehicle body. It should be noted that, to ensure the connection stability of the motor wiring harness sheath 100 on the vehicle body, in some embodiments, the number of sheath fixing parts 11 is multiple. In this first embodiment, the number of sheath fixing parts 11 is two. It is worth mentioning that one of these two sheath fixing parts 11 is formed at one end of the straight segment 105, and the other is formed at the other end of the straight segment 105; that is, the two sheath fixing parts 11 are arranged opposite to each other on the straight segment 105. The provision of two mounting points helps to ensure the connection stability of the motor wiring harness sheath 100 on the vehicle body.

[0036] Preferably, the sleeve fixing hole 110 on one of the two sleeve fixing parts 11 is a waist hole. By adjusting the position of the fastener in the waist hole, this facilitates the fixed connection between the motor wiring harness sleeve 100 and the vehicle body.

[0037] For example, such as Figure 1 , Figure 5 As shown, to reduce the weight of the motor wiring harness sheath 100, a sheath weight-reducing groove 111 is also provided on the sheath fixing part 11. Specifically, the sheath weight-reducing groove 111 is formed on the bottom surface of the lower part of the sheath fixing part 11. Preferably, the opening of the sheath weight-reducing groove 111 faces downward (such as the bottom of the vehicle body). This helps to prevent water accumulation in the sheath weight-reducing groove 111.

[0038] For example, such as Figure 1 , Figure 5As shown, to improve the structural strength of the motor wiring harness sheath 100, the motor wiring harness sheath 100 further includes a reinforcing portion 12. Specifically, the reinforcing portion 12 is formed on the outer surface of the sheath body 10, but is not limited thereto. Preferably, the reinforcing portion 12 protrudes from the outer surface of the sheath body 10, and the extending direction of the reinforcing portion 12 includes, but is not limited to, the axial direction of the straight segment 105, the circumferential direction of the straight segment 105, the axial direction of the bent segment 106, and the circumferential direction of the bent segment 106.

[0039] For example, to prevent water accumulation in the motor wiring harness sheath 100, the motor wiring harness sheath 100 also includes a water passage hole 13, which is used to prevent water accumulation inside the motor wiring harness sheath 100. This helps to prevent water accumulation from damaging the performance of the motor wiring harness 1 inside the motor wiring harness sheath 100.

[0040] For example, to reduce and suppress vibration loads transmitted from the vehicle body to the motor wiring harness 1, the motor wiring harness sheath 100 also includes vibration damping pads (not shown in the figure). Specifically, the vibration damping pads are installed inside the sheath body 10. Preferably, the vibration damping pads are made of materials related to vibration isolation and noise reduction, such as butyl rubber and rubber-plastic composites. This helps to prevent the motor wiring harness 1 from experiencing large-amplitude forced vibrations due to environmental excitations, thereby solving problems such as the motor wiring harness 1 being easily subjected to pulling and wear.

[0041] Example 2 A second aspect of this utility model provides a wiring harness assembly including a motor wiring harness sheath as described in Embodiment 1.

[0042] Furthermore, such as Figure 6 As shown, the wiring harness assembly also includes a motor wiring harness 1. Specifically, the main wire of the motor wiring harness 1 is installed within the main wire protection section 101 of the motor wiring harness sheath 100, and the branch wires of the motor wiring harness 1 are installed within the branch wire protection section 102 of the motor wiring harness sheath 100. It should be noted that the motor wiring harness 1 referred to here is the wiring harness connecting the vehicle's control system and the motor, used to provide stable and reliable power transmission to the motor while ensuring the accuracy of signal transmission. This contributes to the long service life of the wiring harness assembly.

[0043] Example 3 A third aspect of this utility model provides a vehicle that includes a wiring harness assembly as described in Embodiment 2, which is beneficial to improving the safety and reliability of the vehicle.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
