Description

Technical Field

[0001] This utility model relates to the field of wire harness bracket technology, specifically a high-voltage wire harness bracket for blocking resonance. Background Technology

[0002] Automotive wiring harnesses form the core of a vehicle's electrical network, connecting and enabling the electrical and electronic components to function. Without wiring harnesses, there would be no automotive electrical system. Currently, whether in high-end luxury cars or economy cars, the wiring harness structure is basically the same, consisting of wires, connectors, corrugated tubing, and tape. It must ensure the transmission of electrical signals, guarantee the reliability of circuit connections, supply the specified current to electronic and electrical components, and prevent electrical short circuits. With the increasing functionality of automobiles and the widespread application of electronic control technology, the number of electrical components and wires is also increasing, significantly increasing the number of circuits and power consumption in vehicles, making wiring harnesses thicker and heavier. This presents a major problem: how to efficiently and rationally arrange a large number of wiring harnesses within the limited space of a car, maximizing their functionality, has become a challenge for the automotive manufacturing industry. Consequently, fixing the wiring harness routing and converging the wire exits have become urgent issues. This is where wiring harness brackets come in, with a particularly strong demand for them in mid-to-high-end vehicles. Utility Model Content

[0003] To address the above problems, this utility model provides a high-voltage wiring harness bracket that blocks resonance, thus solving the aforementioned issues.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage wiring harness bracket for blocking resonance, comprising a bracket body, the bracket body being U-shaped, with both ends of the bracket body bent outwards to form folded edges, each folded edge having an installation hole, each installation hole having a shock-absorbing pad inserted into it, a metal bushing inserted into the shock-absorbing pad, and multiple cable tie holes on the bracket body.

[0005] Preferably, the shock-absorbing pad is cylindrical with a smaller top and a larger bottom, and the shock-absorbing pad is provided with a snap-fit ​​groove. An upper pressure ring is fixed to the upper end of the snap-fit ​​groove, and a lower pressure ring is fixed to the lower end of the snap-fit ​​groove.

[0006] Preferably, the shock-absorbing pad has a cavity inside, and multiple countersunk holes are formed at the upper and lower ends of the cavity along its circumference.

[0007] Preferably, the shock-absorbing pad is provided with a plurality of rubber columns, which are located in the chamber, and the upper and lower ends of the rubber columns are respectively connected to the countersunk holes.

[0008] Preferably, the rubber column includes a connecting column, a pressure-bearing part, and an extrusion part. The connecting column is located in the middle of the rubber column and is spindle-shaped with small ends and a large center. The pressure-bearing part is located in the center of the connecting column. There are two extrusion parts, which are symmetrically arranged on the outside of the connecting column. The opposite ends of the two extrusion parts are fixedly connected to the rubber column.

[0009] Preferably, the upper and lower ends of the pressure-bearing part are chamfered.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. During vehicle operation, this device reduces vehicle vibration and friction between wiring harnesses, thereby reducing noise transmission into the vehicle. It ensures the harness remains fixed and prevents resonance. By setting up a bracket body to protect the vehicle's high-voltage wiring harness, it straightens and corrects the wiring harness routing, gathers the wiring harness outlets, and fixes the high-voltage wiring harness. During vehicle operation, it prevents the wiring harness from contacting the sheet metal and abrading the wire insulation, which could lead to a short circuit. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] Please see Figure 1 , Figure 2 and Figure 3 A high-voltage wiring harness bracket for blocking resonance includes a bracket body 1, which is U-shaped with outwardly bent edges at both ends. Mounting holes 12 are provided on each of the bent edges, which serve as mounting legs for easy fixation to the vehicle's chassis suspension. Mounting holes 12 are also provided on the mounting legs, and shock-absorbing pads 2 are respectively secured to the mounting legs. Metal bushings 3 are inserted into the shock-absorbing pads 2. Multiple cable tie holes 11 are provided on the bracket body 1. M6 bolts are used to pass through the metal bushings 3 from the upper end of the mounting legs to fix the bracket body 1 to the vehicle body. Cable ties are used to securely connect the high-voltage wiring harness to the bracket body 1 through the cable tie holes 11, protecting the high-voltage wiring harness inside the bracket body 1. The metal bushings 3 are made of DC01 material; the shock-absorbing pads 2 are 13.5mm high, made of EPDM material, and have a hardness of 55-65HA.

[0021] Please see Figure 2 , Figure 3 and Figure 4 The shock-absorbing pad 2 is cylindrical, with a smaller top and a larger bottom. A snap-fit ​​groove 21 is provided on the shock-absorbing pad 2. An upper pressure ring 24 is fixed to the upper end of the snap-fit ​​groove 21, and a lower pressure ring 25 is fixed to the lower end of the snap-fit ​​groove 21. The shock-absorbing pad 2 is snapped into the mounting hole 12 through the snap-fit ​​groove 21. Simultaneously, when the shock-absorbing pad 2 is snapped into the mounting hole 12, the upper pressure ring 24 and the lower pressure ring 25 on the snap-fit ​​groove 21 will press against the edge of the mounting hole 12, clamping the shock-absorbing pad 2 onto the mounting hole 12 and preventing it from falling off, thus facilitating its installation.

[0022] Please see Figure 4 , Figure 5 and Figure 6The shock-absorbing pad 2 has a cavity 22 inside. Multiple countersunk holes 23 are formed along the circumference of the upper and lower ends of the cavity 22. Multiple rubber pillars 4 are disposed inside the shock-absorbing pad 2. The rubber pillars 4 are located in the cavity 22, and their upper and lower ends are connected to the countersunk holes 23. The countersunk holes 23 serve to position and limit the rubber pillars 4, facilitating their fixation and allowing for orderly installation inside the shock-absorbing pad 2. Each rubber pillar 4 includes a connecting pillar 41, a pressure-bearing part 42, and a compression part 43. The connecting pillar 41 is located in the middle of the rubber pillar 4 and is spindle-shaped, with smaller ends and a larger center. The pressure-bearing part 42 is located in the middle of the connecting pillar 4. At the center of the connecting column 41, there are two extrusion parts 43. The extrusion parts 43 are symmetrically arranged on the outside of the connecting column 41. The opposite ends of the two extrusion parts 43 are fixedly connected to the rubber column 4. The upper and lower ends of the pressure-bearing part 42 are chamfered. When fixed by M6 bolts, the bolts squeeze the metal bushing 3, and the metal bushing 3 squeezes the shock-absorbing pad 2. After the shock-absorbing pad 2 is squeezed, the rubber column 4 will be compressed. At this time, the opposite ends of the two extrusion parts 43 will apply pressure to the pressure-bearing part 42. Due to the chamfering effect of the pressure-bearing part 42, the opposite ends of the two extrusion parts 43 will expand outward, thus squeezing the shock-absorbing pad 2 and making the contact between the shock-absorbing pad 2 and the mounting hole 12 tighter.

[0023] When installing and using this device, the shock absorber 2 is inserted into the mounting hole 12, and then the metal bushing 3 is inserted into the shock absorber 2. Finally, the metal bushing 3 is fixed to the car body by passing through the upper end face of the M6 ​​bolt. The high-voltage wiring harness is protected inside the bracket body 1. Specifically, it is used in the position directly above the chassis suspension. This position has limited space and the wiring harness has a single route. This device protects the car's high-voltage wiring harness, straightens and corrects the wiring harness route, and fixes the wiring harness to prevent it from contacting the sheet metal and abrading the wire insulation when the wiring harness shakes, which could lead to a short circuit. It reduces the vibration and friction between the wiring harness during vehicle operation and reduces the noise transmitted into the car. This device can ensure that it is fixed and will not fall off, and it can also play a role in shock absorption.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
