Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harnesses, specifically to a wiring harness bracket with a dual shock absorption structure. Background Technology

[0002] During vehicle operation, vibrations occur. To prevent wear and tear on the wiring harness during this process, a vibration-damping structure is needed to extend its lifespan.

[0003] Currently, most brackets on the market are single-damping structures. Single-damping structures have an uneven absorption effect on high-frequency and low-frequency vibrations, which can easily lead to resonance. After long-term use, rubber parts are prone to fatigue. Therefore, a double-damping structure bracket was studied to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a wire harness bracket with a dual shock absorption structure to solve at least one of the above-mentioned technical problems.

[0005] The technical solution of this utility model is: a wire harness bracket with a dual shock absorption structure, comprising a bracket body, characterized in that the bracket body is a sheet metal part, the bracket body is stepped, the bracket body includes an upper plate and a lower plate, the upper plate and the lower plate are connected by a connecting plate, a fixing hole is opened in the center of the lower plate, a first shock-absorbing rubber washer is installed in the fixing hole, and a second shock-absorbing rubber washer is fixed to the bottom of the upper plate by a cable tie;

[0006] The connecting plate is provided with a through hole, and the upper surface of the second shock-absorbing rubber washer is provided with a groove. The width of the groove is the same as the width of the upper plate. The cable tie passes through the through hole and is fixed to the upper surface of the upper plate and the lower surface of the second shock-absorbing rubber washer.

[0007] The second shock-absorbing rubber washer has three threading holes, and the direction of the threading holes is perpendicular to the length direction of the second shock-absorbing rubber washer.

[0008] This invention reduces vibration transmission rate and the risk of wire harness resonance by incorporating shock-absorbing washers at both the top and bottom ends of the sheet metal bracket body, providing a dual shock-absorbing structure for wire harnesses operating across motion zones. The invention features a simple structure, is easy to install and disassemble, and extends the service life of the wire harness.

[0009] Further preferably, the depth of the groove is the same as the thickness of the upper plate. This ensures a flush surface, facilitating subsequent installation in different locations within the vehicle.

[0010] Further preferably, the threading hole has a notch, and the notch is opened in an upward or downward direction.

[0011] The notch allows for easy entry and exit of wire harnesses, facilitating wiring.

[0012] In a further preferred embodiment, the connecting plates are arranged at an angle, and the connection points between the connecting plates and the upper plate and the lower plate are both arc-shaped.

[0013] Reduce damage to the wire harness caused by sharp points.

[0014] Preferably, the height of the second shock-absorbing rubber washer is not greater than the length of the connecting plate, and the through hole on the connecting plate is a rectangular square hole.

[0015] This ensures the stability of the cable ties after securing the item.

[0016] Further preferably, the length of the upper plate is greater than the length of the lower plate, and a reinforcing rib is provided on the inner side of the connection between the lower plate and the connecting plate.

[0017] This increases the connection strength and ensures stability after installation. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Reference Figs. 1-3As shown, a wire harness bracket with a dual shock absorption structure includes a bracket body, which is a sheet metal part with a stepped shape. The bracket body includes an upper plate 2 and a lower plate 1, which are connected by a connecting plate 3. A fixing hole is opened in the center of the lower plate, and a first shock-absorbing rubber washer 4 is installed in the fixing hole. A second shock-absorbing rubber washer 5 is fixed to the lower part of the upper plate by a cable tie 6. The connecting plate has a through hole 7, and the upper surface of the second shock-absorbing rubber washer has a groove 11. The width of the groove is the same as the width of the upper plate. The cable tie passes through the through hole and is fixed to the upper surface of the upper plate and the lower surface of the second shock-absorbing rubber washer. The second shock-absorbing rubber washer has three wire holes 8, and the opening direction of the wire holes is perpendicular to the length direction of the second shock-absorbing rubber washer.

[0024] This invention reduces vibration transmission rate and the risk of wire harness resonance by incorporating shock-absorbing washers at both the top and bottom ends of the sheet metal bracket body, providing a dual shock-absorbing structure for wire harnesses operating across motion zones. The invention features a simple structure, is easy to install and disassemble, and extends the service life of the wire harness.

[0025] Further optimization involves ensuring that the depth of the groove matches the thickness of the upper plate. This guarantees a flush surface, facilitating subsequent installation in different locations within the vehicle.

[0026] Further optimized, the wire hole is provided with a notch 9, which is opened facing upwards or downwards. The notch facilitates the entry and exit of the wire harness, making wiring easier.

[0027] Further optimization involves the connecting plates being arranged at an angle, with both the connection points between the connecting plates and the upper plate and the connection points between the connecting plates and the lower plate being arc-shaped. This reduces damage to the wire harness caused by sharp edges.

[0028] Further optimization involves ensuring that the height of the second shock-absorbing rubber washer is no greater than the length of the connecting plate, and that the through hole on the connecting plate is a rectangular square hole. This ensures the stability of the cable tie after it is secured.

[0029] Further optimization involves an upper plate being longer than the lower plate, and a reinforcing rib 10 being provided on the inner side of the connection between the lower plate and the connecting plate. This increases the connection strength and ensures stability after installation.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
