Description

Technical Field

[0001] This utility model belongs to the field of wiring harnesses for new energy vehicles. Specifically, this utility model relates to a wiring harness fixing bracket for new energy commercial vehicles. Background Technology

[0002] Currently, new energy vehicles have many more electrical components compared to traditional gasoline vehicles, involving numerous high-voltage wiring harnesses. In areas where both high and low voltage harnesses need to be secured simultaneously, if they are not classified and layered for secure fixing, the stacking of high and low voltage harnesses can lead to crosstalk and electromagnetic interference. High-voltage harnesses, with their high voltage and high current, are prone to capacitive coupling and electromagnetic interference. Stacking them with low-voltage harnesses can cause signal transmission failures in the low-voltage harnesses and also affect the stability of the high-voltage output. Furthermore, current technology typically uses cable ties and pipe clamps to secure the harnesses; however, relying solely on cable ties for securing the harnesses is unreliable. During vehicle operation, the harnesses are prone to shaking, which can cause connectors to move, leading to poor contact and safety hazards. Limited space also prevents the provision of additional pipe clamps for separate securing of high and low voltage harnesses, making it difficult to meet the overall vehicle wiring harness assembly requirements.

[0003] A search revealed a Chinese patent published on March 17, 2020, disclosing an automotive wiring harness fixing device and an automobile, publication number CN110890732A. This device is used for installation between the door sill and the vehicle floor. The device includes a fixing plate and a flip plate that interlock. One end of the fixing plate is hinged to the flip plate, and the other end is connected via a connector. A wiring harness guide groove is provided between the fixing plate and the flip plate to accommodate the automotive wiring harness. However, it cannot achieve classified fixing of the wiring harness.

The connecting plate 3 is mounted on a vehicle frame 4. A low-voltage wiring harness 5 is mounted on the first fixing plate 1, and a high-voltage wiring harness 6 is mounted on the second fixing plate 2. By mounting the low-voltage wiring harness 5 on the first fixing plate 1 and the high-voltage wiring harness 6 on the second fixing plate 2, the wiring harnesses can be classified and fixed.

[0024] like Figure 2 and Figure 3 As shown, the first fixing plate 1 is provided with a first slot 9, and the first slot 9 is provided with a first cable tie 7. The low-voltage wire harness 5 is connected to the first fixing plate 1 through the first cable tie 7. Multiple sets of first slots 9 are provided on the first fixing plate 1. The first slots 9 are used to connect with the first cable ties 7. The low-voltage wire harness 5 is fixed by the first cable ties 7 being placed in the first slots 9.

[0025] The second fixing plate 2 is provided with a second slot 10, and a second cable tie 8 is provided on the second slot 10. The high-voltage wire harness 6 is connected to the second fixing plate 2 through the second cable tie 8. The second fixing plate 2 is provided with multiple sets of second slots 10. The second slots 10 are used to connect with the second cable ties 8. The high-voltage wire harness 6 is fixed by the second cable ties 8 being placed on the second slots 10.

[0026] A first reinforcing rib 11 is provided at the junction of the first fixing plate 1 and the second fixing plate 2; a second reinforcing rib 12 is provided at the junction of the second fixing plate 2 and the connecting plate 3. The first reinforcing rib 11 serves to fix the bend between the first fixing plate 1 and the second fixing plate 2, and the second reinforcing rib 12 serves to fix the bend between the second fixing plate 2 and the connecting plate 3.

[0027] The connecting plate 3 is provided with mounting holes 13, and the connecting plate 3 and the frame 4 are connected by bolts 14. The connecting plate 3 is provided with mounting holes 13, and the mounting holes 13 and the frame 4 are connected by bolts 14, so as to fix the connecting plate 3 to the frame 4.

[0028] The first fixing plate 1 has a first guide plate 15 at one end and a second guide plate 16 at the other end. The first guide plate 15 and the second guide plate 16 serve to guide the installation process.

[0029] Multiple sets of first slots 9 and second slots 10 are provided; multiple sets of first cable ties 7 and second cable ties 8 are also provided. In this embodiment, four first slots 9 are provided, respectively located at both ends of the first fixing plate 1. Two first cable ties 7 provide better fixing effect. There are two first slots 9 that cooperate with each first cable tie 7 on the first fixing plate 1, resulting in a more secure fixation.

The first fixing plate 1 has multiple sets of slots for connecting with cable ties, thus fixing the first cable tie 7 to the first fixing plate 1, and connecting the low-voltage wiring harness 5 through the first cable tie 7 and the first fixing plate 1. The second fixing plate 2 has multiple sets of slots for connecting with cable ties, thus fixing the second cable tie 8 to the second fixing plate 2, and connecting the high-voltage wiring harness 6 through the second cable tie 8 and the second fixing plate 2. The first reinforcing rib 11 fixes the bend between the first fixing plate 1 and the second fixing plate 2, and the second reinforcing rib 12 fixes the bend between the second fixing plate 2 and the connecting plate 3.
