The high-voltage electrical box is fixed on the mounting bracket, the mounting bracket is fixed on the electromechanical coupling transmission (GMC), and the electromechanical coupling transmission is fixed on the car engine. When the car starts or drives, the engine vibration will be transmitted to the high-voltage wire harness through the electromechanical coupling transmission, the mounting bracket and the high-voltage electrical box. The main body of the high-voltage wire harness needs to be fixed to the body sheet metal through the bracket, which will cause the engine vibration to be transmitted to the body sheet metal through the high-voltage wire harness. Because the bracket for fixing the high-voltage wire harness is set near the position of the fixed brake pedal, the brake pedal and the high-voltage wire harness bracket are fixed on both sides of the front wall panel sheet metal at the same time. The brake pedal is fixed on the cab side of the front wall panel sheet metal, and the high-voltage wire harness bracket is fixed on the cabin side of the front wall panel sheet metal. Affected by the vibration of the high-voltage wire harness, the pedal will vibrate more obviously, affecting the driving experience and the NVH performance of the entire vehicle.

[0035] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

The wire body of the high-voltage wire harness 5 is fixed to the vehicle body 1 through the first wire harness guard plate bracket 6. The first wire harness guard plate bracket 6 has the function of fixing and buffering the vibration of the high-voltage wire harness 5. There is also a wire harness guard plate bracket 6 between the first wire harness guard plate bracket 6 and the vehicle body 1. A guard plate vibration isolation pad 7 is provided to further cushion and reduce vibration. Meanwhile, a long curved groove 601 is provided on the first harness guard plate bracket 6 to accommodate and secure the high-voltage harness 5. The long curved groove 601 is configured as a long strip to increase the contact area between the long curved groove 601 and the high-voltage harness 5, thereby enhancing the securing and vibration reduction effect of the high-voltage harness 5. Combined with the guard plate vibration isolation pad 7 mentioned above, the vibration of the high-voltage harness 5 is fully reduced, thereby reducing the vibration of the pedal. Specifically, there is no limit to the number of first harness guard plate brackets 6. Furthermore, the guard plate vibration isolation pad 7 is made of an elastic material, such as rubber, plastic, or silicone, with silicone being preferred.

[0039] The beneficial effects of this embodiment are as follows: a long curved groove 601 is provided on the first wire harness guard plate bracket 6 to increase the contact area between the high-voltage wire harness 5 and the first wire harness guard plate bracket 6 and reduce the vibration of the high-voltage wire harness 5. The first wire harness guard plate bracket 6 is also provided with multiple connecting parts 602 to increase the connection stability with the vehicle body 1. At the same time, a guard plate vibration isolation pad 7 is connected to the connecting part 602 to further improve the vibration reduction effect.

[0040] Example 2

[0041] Based on Example 1, the difference from Example 1 is that:

[0042] like Figure 5 As shown, the high-voltage wire harness 5 includes at least two high-voltage wires. The long curved groove body 601 includes a deep groove section 6011 for longitudinally accommodating the high-voltage wires, a transition section 6012 connected to the deep groove section 6011, and a wide groove section 6013 connected to the transition section 6012 for transversely accommodating the high-voltage wires. The high-voltage wires are twisted at an angle under the restraining effect of the long curved groove body 601. Figure 4As shown, the long curved groove body 601 is provided with multiple groups of through-hole groups 8 for inserting wires, and each group of through-hole groups 8 includes two holes respectively arranged on both sides of the long curved groove body 601. The first harness guard plate bracket 6 is provided with at least three connecting parts 602, and the connecting position lines of any three connecting parts 602 are distributed in a triangular shape. The mounting surfaces of all the connecting parts 602 include at least two non-parallel surfaces. Figure 5 As shown, it also includes a second harness guard plate bracket 9 connected to the high-voltage harness 5, and the second harness guard plate bracket 9 is provided with at least two receiving grooves 901 for accommodating high-voltage wires, and any two adjacent receiving grooves 901 are respectively provided with a separation strip 902 for separating the high-voltage wires. Figure 4 As shown, a plurality of through hole groups 8 are provided on the second wire harness guard plate bracket 9 .

[0043] The commonly used high-voltage wire harness 5 generally includes two high-voltage wires, but it does not exclude the case of including more than two high-voltage wires. In order to facilitate the arrangement and routing of the high-voltage wires, the long curved groove body 601 is set as multiple sections, including a deep groove section 6011, a transition section 6012 and a wide groove section 6013. The high-voltage wires are longitudinally accommodated in the deep groove section 6011. Figure 5 As shown, the high-voltage wires are arranged longitudinally in the deep groove section 6011 and transversely or in a direction different from the longitudinal direction in the wide groove section 6013. They are bent or twisted in the transition section 6012, thereby ensuring the orderly positioning of the high-voltage wires. Furthermore, the arrangement can be twisted at any angle based on the configuration of the deep groove section 6011 and the wide groove section 6013. This not only ensures the neat arrangement of the wire harness, but also reduces vibration of the high-voltage wires by twisting the high-voltage wire harness 5, thereby improving the vibration reduction effect. A set of through holes 8 is provided for inserting cable ties to further secure the high-voltage wire harness 5 within the elongated curved groove body 601, further reducing vibration of the high-voltage wire harness 5. Specifically, a single cable tie is inserted through the holes on both sides and then tightened. Multiple sets of through holes 8 can each be inserted with multiple cable ties. The connecting portion 602 is used to connect to the vehicle body 1. At least three connecting portions 602 are provided, and any three connecting portions 602 form a triangle, thereby improving connection stability and reducing vibration. Each connecting portion 602 is connected to a different surface of the vehicle body 1, thereby improving the spatial stability of the connection between the first wiring harness slide plate bracket and the vehicle body 1. The second wire harness guard plate bracket 9 is also used to fix the high-voltage wire harness 5. Unlike the first wire harness guard plate, the second wire harness guard plate is provided with a receiving groove 901, and a dividing strip 902 is provided between the receiving grooves 901, which can separate the high-voltage wires in the high-voltage wire harness, further restrict the high-voltage wires, and reduce the vibration of the high-voltage wires and the high-voltage wire harness 5 as a whole.

[0044] Furthermore, the inner surface of the long curved groove 601 of the first wire harness guard plate bracket 6 is pasted with elastic PU foam fabric, which not only improves the contact surface between the high-voltage wire harness 5 and the first wire harness guard plate bracket 6, but also reduces the vibration of the first wire harness guard plate bracket 6 caused by the shaking of the high-voltage wire harness 5.

[0045] The remaining features and working principles of this embodiment are consistent with those of embodiment 1.

Figure 6 As shown, the mounting bracket 3 includes a main mounting frame 301, which is made by bending and stamping a single piece of sheet metal and has multiple mounting holes for connecting to the electromechanical coupling transmission 2. The mounting bracket 3 also includes a reinforcement frame 302 connected to the main mounting frame 301. The top and side surfaces of the reinforcement frame 302 are welded to the main mounting frame 301, and the edges of the reinforcement frame 302 are provided with reinforcing ribs.

[0049] The pedal assembly 10 is arranged inside the vehicle, specifically on the forearm plate of the vehicle body 1, and the first wire harness guard plate bracket 6 is installed on the back of the pedal assembly 10, that is, on the other side of the forearm plate. At the same time, the first wire harness guard plate bracket 6 and the pedal assembly 10 are staggered to avoid the vibration of the first wire harness guard plate bracket 6 being directly transmitted to the pedal assembly 10, thereby further reducing the shaking of the pedal assembly 10. The main mounting part of the mounting bracket 3 is made of a single piece of sheet metal to ensure strength and reduce vibration, and multiple mounting holes are provided to ensure installation stability. A reinforcement frame 302 is provided to suppress the vibration of the main mounting frame 301, and the reinforcement frame 302 is welded to the main mounting frame 301 to ensure strength.

[0050] Specifically, such as Figure 1-4 As shown, the vehicle body 1 includes a front floor sheet metal and a front wall sheet metal, the pedal assembly 10 is mounted on the inner side of the front wall sheet metal, and the first harness guard plate bracket 6 is mounted on the outer side of the front wall sheet metal, as shown in FIG. Figure 2 As shown, the pedal assembly 10 and the first harness guard plate bracket 6 are staggered. Figure 3-4 As shown, the second harness guard bracket 9 is installed on the bottom surface of the front floor sheet metal.

[0051] Further, such as Figure 3As shown, the high-voltage wire harness 5 is also connected to a fixed bracket 11, which is fixed as a whole on the electromechanical coupling gearbox 2. At the same time, one end of the high-voltage wire harness 5 close to the electromechanical coupling gearbox 2 is fixed on the fixed bracket 11, and an elastic PU foam fabric is also provided inside the fixed bracket 11 to further reduce the vibration of the high-voltage wire harness 5.
