Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness fixing technology, specifically an automotive wiring harness fixing component. Background Technology

[0002] Automotive wiring harnesses form the core of a vehicle's electrical network, running through various parts of the car and connecting various electrical devices to transmit electrical signals and power. They are crucial components ensuring the normal operation of the vehicle. With the rapid development of the automotive industry, vehicles are becoming increasingly feature-rich, with ever-increasing levels of intelligence and electrification. This has led to a significant increase in the number and complexity of automotive wiring harnesses. In modern vehicles, wiring harnesses are indispensable for connections from engine control and chassis systems to body electronics and safety systems. For example, compared to traditional gasoline vehicles, new energy vehicles have added battery management systems and motor control systems, resulting in a greater number and variety of wiring harnesses with more complex layouts. In intelligent connected vehicles, the addition of various sensors, radars, and communication devices further exacerbates the complexity of the wiring harness system.

[0003] Many existing automotive wiring harness mounting components use a fixed structure, meaning the position of the mounting clip cannot be adjusted once it's determined. However, wiring harness layouts vary between different car models, and even within the same model, different configurations may have different numbers and diameters of wiring harnesses. This fixed structure cannot accommodate the spacing requirements of different wiring harnesses, often leading to problems such as harness compression and tangling during installation. This affects heat dissipation and lifespan of the wiring harness, and may even cause poor signal transmission, resulting in electrical faults.

[0004] Therefore, an automotive wiring harness fixing component is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this paper addresses the issue that many current automotive wiring harness fixing components use a fixed structure, where the position of the fixing clip cannot be adjusted once it is determined. However, the wiring harness layout varies between different vehicle models, and even within the same vehicle model, different configurations may have different numbers and diameters of wiring harnesses. This fixed structure cannot accommodate the spacing requirements of different wiring harnesses, often leading to problems such as wire harness compression and tangling during installation. This affects the heat dissipation and lifespan of the wiring harness, and may even cause poor signal transmission, resulting in electrical faults.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The automotive wiring harness fixing assembly of this utility model includes an adjustable fixing assembly, a buffer shock absorption assembly installed at the bottom of the adjustable fixing assembly, and an installation device installed on the side of the buffer shock absorption assembly; the adjustable fixing assembly includes a support frame, a sliding groove is provided inside the support frame, and a slider is slidably connected inside the sliding groove; a limit groove is provided on the side of the sliding groove, and a limit rod is engaged inside the limit groove; a fixing clip is fixedly connected to the top of the slider, and a hinge is fixedly connected to one side of the fixing clip; a rotating clip is fixedly connected to the other side of the hinge, and a bolt is threadedly connected to the end of the rotating clip.

[0007] Preferably, the rotating clip forms a rotating structure with the fixing clip via a hinge, and the rotating clip forms a threaded structure with the fixing clip via bolts.

[0008] Preferably, the fixing card forms a sliding structure with the support frame through a slider, a sliding groove, and a locking structure with the support frame through a limiting rod, a limiting groove, and a locking structure.

[0009] Preferably, the buffer and shock absorption assembly includes a rubber pad, the inside of which is provided with a groove, and a protrusion is engaged inside the groove, and a spring is fixedly connected to the end of the protrusion.

[0010] Preferably, the grooves are arranged at equal intervals with respect to the interior of the rubber pad, and the protrusions and grooves form an engaging structure.

[0011] Preferably, the protrusion and the spring are integrated, and the spring and the groove are aligned with the vertical central axis.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, with its adjustable fixing component, offers significant advantages in adjustable fixing. The support frame within the adjustable fixing component has an internal groove, allowing the slider to slide smoothly within the groove, flexibly adjusting the position of the fixing clip. This design enables the fixing clip to easily change position according to differences in wiring harness layout across different vehicle models, as well as variations in the number and diameter of wiring harnesses under different configurations within the same vehicle model. This precisely adapts to different wiring harness spacing requirements, effectively avoiding the wiring harness compression and tangling problems common in traditional fixing structures. It ensures heat dissipation and extends the service life of the wiring harness, and reduces electrical faults such as poor signal transmission caused by improper wiring harness layout. Furthermore, the engaging connection between the limiting groove and the limiting rod firmly fixes the fixing clip to the support frame after it is adjusted to the appropriate position, ensuring that the fixing clip will not shift due to vibration or other factors during vehicle operation, thus guaranteeing the stability of the wiring harness fixation. Furthermore, the rotating clip, with its hinge and fixed clip forming a rotating structure, combined with the threaded connection of bolts, not only facilitates the insertion and removal of the wiring harness but also allows for flexible adjustment of the clamping force according to the diameter of the harness, achieving a tight clamping effect and further enhancing the fixation. This prevents the harness from wobbling within the fixed clip. In terms of cushioning and shock absorption, the damping component effectively addresses vibrations of varying frequencies and amplitudes generated during vehicle operation. It reduces the transmission of vibration to the adjustable fixed component and the wiring harness, decreasing friction and collisions between the harness and the fixed component caused by vibration. This prevents wear on the harness sheath and breakage of internal wires, while also preventing loosening of the fixed component connection. This significantly improves the stability and lifespan of the wiring harness in complex vibration environments. Regarding installation, the side-mounted installation device simplifies the entire assembly process. Compared to traditional fixed components requiring multiple tools for tightening, it effectively reduces assembly time and labor costs, while also reducing the risk of improper installation, bringing great convenience to automotive production and subsequent maintenance.

[0014] 2. This utility model incorporates a buffer and shock-absorbing component, whose design is particularly ingenious, significantly improving the shock absorption effect. The rubber pad itself possesses excellent elasticity and cushioning properties, absorbing a portion of the vibration energy and reducing vibration transmission. The equally spaced grooves and protrusions within the pad form a tight interlocking structure. This structure increases the deformation space of the rubber pad, allowing it to more fully exert its cushioning effect when subjected to vibration. Furthermore, the interlocking connection ensures the stable position of the protrusions within the grooves, preventing component misalignment due to vibration and ensuring the stability of the shock-absorbing structure. Moreover, the protrusions and springs are integrated, with the spring coinciding with the vertical central axis of the groove. When subjected to vibration, the spring can extend and retract along the central axis of the groove, precisely buffering and absorbing vibration energy, further weakening vibration transmission. The interlocking of rubber pads, grooves, and protrusions, along with the synergistic effect of springs, addresses vibrations of varying frequencies and amplitudes during vehicle operation from multiple dimensions. This significantly reduces friction and collisions between the wiring harness and the mounting components caused by vibration, effectively preventing wear on the harness sheath and breakage of internal wires. It also prevents loosening of the mounting components, significantly improving the stability and lifespan of the wiring harness in complex vibration environments. In terms of installation, the side-mounted mounting device simplifies the entire assembly process. Compared to traditional mounting components that require multiple tools for tightening, it effectively reduces assembly time and labor costs, while also reducing the risk of improper installation, bringing great convenience to vehicle production and subsequent maintenance.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Example 1

[0023] like Figure 1 The present invention relates to an automotive wiring harness fixing assembly, comprising an adjustable fixing assembly 1, a shock-absorbing and damping assembly 2, and a mounting device 3.

[0024] Please see Figure 1 and Figure 4 The diagram shows an automotive wiring harness fixing assembly, including an adjustable fixing assembly 1. A shock-absorbing assembly 2 is mounted on the bottom of the adjustable fixing assembly 1, and a mounting device 3 is mounted on the side of the shock-absorbing assembly 2. The adjustable fixing assembly 1 includes a support frame 101, with a sliding groove 102 inside the support frame 101. A slider 103 is slidably connected inside the sliding groove 102. A limiting groove 104 is provided on the side of the sliding groove 102, and a limiting rod 105 is engaged inside the limiting groove 104. A fixing clip 106 is fixedly connected to the top of the slider 103. A hinge 107 is fixedly connected to one side of the card 106, and a rotating card 108 is fixedly connected to the other side of the hinge 107. A bolt 109 is threadedly connected to the end of the rotating card 108. The rotating card 108 forms a rotating structure with the fixed card 106 through the hinge 107, and the rotating card 108 forms a threaded structure with the fixed card 106 through the bolt 109. The fixed card 106 forms a sliding structure with the support frame 101 through the slider 103 and the slide groove 102, and the fixed card 106 forms an engaging structure with the support frame 101 through the limiting rod 105 and the limiting groove 104.

[0025] Please see Figure 4The diagram shows an automotive wiring harness fixing assembly. The buffer and shock absorption assembly 2 includes a rubber pad 201. The rubber pad 201 has a groove 202 inside, and a protrusion 203 is engaged inside the groove 202. A spring 204 is fixedly connected to the end of the protrusion 203. The grooves 202 are arranged at equal intervals inside the rubber pad 201, and the protrusion 203 and the groove 202 form an engaging structure. The protrusion 203 and the spring 204 are integrated, and the spring 204 and the groove 202 are arranged with their vertical central axes coinciding.

[0026] Working Principle: When fixing the wire harness, the adjustable fixing component 1 is used to first complete the initial position adjustment and clamping. The support frame 101 in the adjustable fixing component 1 provides a stable support base for the entire adjustment structure, and the sliding groove 102 inside provides a path for the movement of the slider 103. When it is necessary to adjust the fixing position according to the layout and quantity of the wire harness, the operator can push the fixing clip 106. At this time, the slider 103, which is fixedly connected to the top of the fixing clip 106, will slide smoothly along the sliding groove 102, driving the fixing clip 106 to move to the appropriate position. During the adjustment process, the limiting groove 104 on the side of the sliding groove 102 and the limiting rod 105 on the slider 103 play a key positioning role. When the fixing clip 106 reaches the predetermined position, the limiting rod 105 is inserted into the corresponding limiting groove 104, which can firmly fix the fixing clip 106 on the support frame 101 and prevent it from shifting due to vibration and other factors during vehicle operation.

[0027] Next, the wire harness is clamped. The rotating clip 108, connected to one side of the fixing clip 106 via a hinge 107, plays a crucial role. The operator can rotate the rotating clip 108 using the hinge 107 to place the wire harness between the fixing clip 106 and the rotating clip 108, then close the rotating clip 108 and tighten it using the bolt 109 threaded to the end of the rotating clip 108. Because the rotating clip 108 and the fixing clip 106 form a threaded structure via the bolt 109, the operator can adjust the tightening of the bolt 109 according to the diameter of the wire harness, thereby changing the clamping force to ensure a tight clamping of the wire harness and prevent it from wobbling within the fixing clip 106.

[0028] When the vehicle vibrates during operation, the damping assembly 2 begins to function, reducing the impact of vibration on the wiring harness and mounting components. The rubber pad 201 in the damping assembly 2 directly contacts the bottom of the adjustable mounting component 1. Its excellent elasticity and cushioning performance initially absorb some of the vibration energy, mitigating the transmission of vibration. The interlocking structure formed by the equally spaced grooves 202 and protrusions 203 inside the rubber pad 201 further enhances the damping effect. When subjected to vibration, the protrusions 203 will move relative to each other within the grooves 202. This interlocking relationship increases the deformation space of the rubber pad 201, allowing it to more effectively dampen vibration, while also ensuring that the protrusions 203 do not easily disengage from the grooves 202, thus ensuring the stability of the damping structure.

[0029] Simultaneously, the spring 204, fixedly connected to the end of the protrusion 203, also participates in the vibration damping process. Since the protrusion 203 and spring 204 are integrated, and the spring 204 and groove 202 are aligned vertically, when vibration is transmitted to this point, the spring 204 will extend and retract along the central axis of the groove 202, absorbing and buffering vibration energy through its elastic deformation, further weakening the transmission of vibration. The synergistic effect of the rubber pad 201, groove 202, protrusion 203, and spring 204 addresses vibrations of different frequencies and amplitudes in multiple dimensions, effectively reducing friction and collisions between the wire harness and the fixing components caused by vibration, protecting the outer sheath and internal wires of the wire harness, and preventing loosening of the fixing component connections.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
