Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness guide bracket technology, specifically an anti-detachment automotive wiring harness guide bracket. Background Technology

[0002] Automotive wiring harnesses are important components of intelligent vehicle control, and they are distributed throughout various parts of the vehicle. Due to their multidirectional distribution within the vehicle, their routing and working environment are generally narrow and compact. To prevent damage caused by repeated movement and friction between the wiring harness and the sheet metal components in the environment due to external forces during vehicle operation, guide brackets are installed to assist in unfavorable locations of the wiring harness distribution. These brackets are used to position the wiring harness, restrict its routing, and organize and protect the wiring harness.

[0003] Existing automotive wiring harness guides include original equipment manufacturer (OEM) brackets and optional self-installation brackets used in subsequent automotive repairs. Self-installed automotive wiring harness guides are largely driven by market demand. Compared to OEM brackets, they can further improve wiring harness stability and installation convenience while meeting basic guidance requirements. For example, existing automotive wiring harness guides, in addition to ensuring wiring harness stability, facilitate bending and guiding control of the wiring harness, reducing its tangling. Alternatively, they may employ a box structure, using bolts or binding to secure the box structure in a spare space on the vehicle body, and using the box for wiring harness guidance control. However, in actual use, while these types of automotive wiring harness guides can organize the wiring harness, the wiring harness routing is often restricted by the environment. The guide bracket can limit and guide a section of the wiring harness, but its guiding protection is poor in areas where the wiring harness is restricted by the surrounding environment or workpieces. The wiring harness is still prone to loosening during prolonged automotive operation, leading to guide detachment and friction damage.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing automotive wiring harness guide brackets. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-detachment automotive wiring harness guide bracket to solve the problem mentioned in the background art, where existing automotive wiring harness guide brackets are easily obstructed and restricted by the surrounding environment when guiding the wiring harness, affecting the guidance and protection of the wiring harness.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-detachment type automotive wiring harness guide bracket, comprising a positioning frame and a positioning plate used for positioning and mounting thereon, as well as binding holes on the positioning frame for positioning the automotive wiring harness; It also includes: an extension located at the end of the positioning frame, and the extension is provided with a positioner for limiting the automotive wiring harness, while the positioner is provided with a damping element to prevent the automotive wiring harness from falling off. An extension strip is fixed to the bottom of the positioning frame and the extension. The extension strip adjusts the twist distribution and positioning of the extension by its own twisting and deformation. At the same time, an elastic damping ring is also sleeved on the outside of the extension. The elastic damping ring is used to splice and gather the edges of adjacent extensions.

[0007] Preferably, the extensions are evenly distributed at the ends of the positioning frame, and the elastic damping rings on adjacent extensions are elastically compressed in a fitted manner, wherein the outer side of the elastic damping ring is set as a regular polygon.

[0008] Preferably, adjacent elastic damping rings are connected to each other by planar edges of regular polygons, wherein the planar edges of the elastic damping rings are in contact with each other, and a permanent magnet is embedded inside the planar edges of the elastic damping rings.

[0009] Preferably, two extension strips are arranged parallel to each other at the bottom of the positioning frame and the extension section, and the extension strips are made of aluminum strips. The connection node between the extension strips and the extension section is at the center of the bottom of the extension section, and a gap is reserved between the extension strips and the extension section outside the connection node.

[0010] Preferably, the locator is composed of a side rod and a central positioning rod, wherein the side rod is symmetrically arranged at the top edge of the extension, and the central positioning rod is fixed at the top center of the extension, wherein the outer side of the central positioning rod is used for the winding and limiting of the automotive wiring harness; The damping component is fixed to the top of the side rod and the positioning rod.

[0011] Preferably, the locator consists only of side rods symmetrically arranged at the top edge of the extension, and the symmetrically distributed side rods restrict the direction of the vehicle wiring harness distribution. The damping component is fixed to the top of the side rod.

[0012] Preferably, a fastening adjuster is also installed at the bottom of the positioning frame and the extension to replace the extension strip; The fastening adjuster includes a rotating component that is rotatably mounted through the end of the positioning frame, and a movable component that is rotatably mounted at the bottom center of the extension. One end of a tension tube is rotatably mounted inside the lower end of the rotating component, and the other end of the tension tube is connected to the interior of the movable component through a flexible rubber tube. Meanwhile, the adjacent extensions are also connected to their bottom movable parts by stretching tubes and flexible hoses.

[0013] Preferably, the rotating component and the tensioning tube form a relatively telescopic structure, and an elastic component is also provided at their through-connection. Meanwhile, the rotating component is internally connected to the tension tube, flexible hose, and moving component, and positioning and fastening are achieved by injecting adhesive into the rotating component.

[0014] Preferably, the extension is configured as a rectangular structure in the middle and a rounded structure at the ends to increase the rotation angle between adjacent extensions. At the same time, adjacent extensions and extensions and positioning frames are elastically connected by elastic damping rings.

[0015] Compared with the prior art, the beneficial effects of the present invention are: this anti-detachment automotive wiring harness guide bracket facilitates the guidance and positioning control of automotive wiring harnesses, while simultaneously guiding and protecting excess wiring harnesses, reducing the problem of unstable guidance and easy loosening and damage of automotive wiring harnesses caused by the regional environment. Its specific details are as follows: 1. The combined extension section guides and positions the automotive wiring harness segments in confined and unfavorable environments. The positioning device also guides the automotive wiring harness without requiring uniform tape wrapping, facilitating independent inspection and replacement of the automotive wiring harness. Furthermore, a deformable extension strip is provided to achieve horizontal bending, projection bending, and spiral bending at the location of the extension, which can meet the guidance and installation distribution of automotive wiring harnesses due to environmental limitations. In this process, the extension can still guide, control, and position the automotive wiring harness, resulting in a stable performance.

[0016] 2. By setting a fastening adjuster consisting of a rotating part, a tensioning tube, a movable part, and a flexible hose, the extension part arranged in combination can be bent in the horizontal plane to achieve the guidance control and positioning of the wire harness. At the same time, after the fastening adjuster is calibrated for use, it can be stabilized by injecting glue. This makes the extension part and positioning frame, which are used for a long time, have good shock resistance and the guiding and positioning effect of automotive wire harness, and are not prone to loosening and falling off of automotive wire harness.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-6 This invention provides a technical solution: an anti-detachment automotive wiring harness guide bracket, comprising a positioning frame 1 and a positioning plate 2 for positioning and installation, and binding holes 3 on the positioning frame 1 for positioning the automotive wiring harness; in this solution, when positioning the automotive wiring harness, the positioning plate 2 and the positioning frame 1 are first installed in the vehicle frame or corresponding power compartment according to their positioning position and the requirements for positioning the automotive wiring harness. For example, by using bolt drilling and binding positioning methods, the positioning frame 1 and the positioning plate 2 can be installed and fixed. The binding holes 3 and the binding straps can be combined to fix the middle section of the automotive wiring harness to the positioning frame 1.

[0021] This solution also includes: an extension 4 located at the end of the positioning frame 1, and the extension 4 is provided with a locator 5 for limiting the automotive wiring harness, and the locator 5 is provided with a damping element 6 to prevent the automotive wiring harness from falling off; the extension 4 is provided so that after the middle section of the automotive wiring harness is positioned by the binding hole 3, the binding strap and the positioning frame 1, the extension 4 is used to guide and position the excess unpositioned automotive wiring harness, and the locator 5 and the damping element 6 are provided to prevent the automotive wiring harness positioned on the extension 4 from loosening and falling off due to external force load during long-term use.

[0022] Specifically, in this solution, the extension strip 7 is fixed to the bottom of the positioning frame 1 and the extension part 4. The extension strip 7 adjusts the twisting distribution and positioning of the extension part 4 through its own twisting and deformation. At the same time, an elastic damping ring 401 is also sleeved on the outside of the extension part 4. The elastic damping ring 401 is used to splice and gather the edges of adjacent extension parts 4. Since automotive wiring harnesses are distributed in the narrow interior space of a car, and multiple wiring harnesses in the same direction are often distributed and scattered, after the middle section of the automotive wiring harness is fixed, the remaining automotive wiring harnesses will extend to the wiring harness inlet / outlet interface or the gaps and corners of other automotive parts. Using only the middle section of the automotive wiring harness for guidance and limitation is insufficient for the fixing of the wiring harnesses in other positions, which are prone to scattering and wear during use. Existing solutions for this part of the wiring harness often involve scattering or uniformly wrapping and binding with tape. When it is necessary to extract and replace a single wiring harness, the operation is extremely inconvenient and can easily cause damage to other wiring harnesses. This solution uses the extension strip 7 to address this issue. Two extension strips 7 are arranged parallel to each other at the bottom of the positioning frame 1 and the extension part 4. The extension strip 7 is made of aluminum strip, and the connection node between the extension strip 7 and the extension part 4 is at the center of the bottom of the extension part 4. A gap is reserved between the extension strip 7 and the extension part 4 outside the connection node. After the extension strip 7 is used and the automotive wiring harness is initially placed in the extension part 4 by the positioning device 5 and the damping device 6, the extension strip 7 can be twisted in the plane, the projection plane, or the spiral state, which can achieve the effect of changing the distribution state between adjacent extension parts 4. After the extension strip 7 is twisted and deformed as a whole, the direction deformation control of the extension part 4 is achieved, so that the extension part 4 can guide and stabilize the automotive wiring harness and extend into the residual gap of the automotive workpiece or the gap of the automotive wiring harness in other directions, so as to isolate and guide the automotive wiring harness in this part. The extension strip 7 is made of a metal with good ductility, such as copper or aluminum.

[0023] Furthermore, the extensions 4 are evenly distributed at the ends of the positioning frame 1, and the elastic damping rings 401 on adjacent extensions 4 are elastically compressed in a fitted manner. The outer side of the elastic damping ring 401 is set as a regular polygon. Adjacent elastic damping rings 401 are connected to each other through the planar edges of the regular polygons, wherein the planar edges of the elastic damping rings 401 are in contact with each other, and a permanent magnet is embedded in the inner side of the planar edge of the elastic damping ring 401. When the extension strip 7 is deformed, the use of the elastic damping rings 401 can reduce the collision between the extensions 4 and the automotive workpiece or other objects, while stabilizing the extensions. The positioning of the extension 4 itself, such as by directly contacting the automotive workpiece through the elastic damping ring 401, provides good protection against vibrations during vehicle operation. The permanent magnet inside facilitates the adsorption and positioning of the elastic damping ring 401. At the same time, if only the plane where the extension strip 7 is located is twisted, the components of the extension 4 can be bent in multiple ways, such as S-shaped bends, to guide and protect the automotive wiring harness. The elastic damping ring 401 facilitates the alignment and assembly of adjacent extensions 4, and the assembly and alignment stability between extensions 4 is improved through its own shape, the use of elasticity and permanent magnet installation.

[0024] In this design, the locator 5 is configured in two types. The first type of locator 5 consists of a side rod 501 and a positioning center rod 502. The side rod 501 is symmetrically positioned at the top edge of the extension 4, and the positioning center rod 502 is fixed at the top center of the extension 4. The outer side of the positioning center rod 502 is used for winding and limiting the automotive wiring harness. The damping element 6 is fixed at the top of the side rod 501 and the positioning center rod 502. In this configuration, when the automotive wiring harness is guided between the side rod 501 and the positioning center rod 502 for positioning through the damping element 6, it is not necessary to wrap and bind the automotive wiring harness with tape. The individual automotive wiring harnesses can be positioned sequentially outside the positioning center rod 502. The positioning is achieved by spiral winding and positioning on the side, and then the spacing between the positioning rod 502 and the side rod 501 is used to achieve the positioning and stabilization of the automotive wiring harness. At the same time, the automotive wiring harness installed by spiral winding and positioning can reduce its looseness and is not easy to loosen when guided and positioned on the extension part 4. It also facilitates the single extraction and repair and replacement of a damaged single automotive wiring harness. There are independent wiring harness routing channels between the left and right sides of the positioning rod 502 and the two side rods 501, so that adjacent automotive wiring harnesses with the same routing can be guided, positioned and separated on the extension part 4, which is convenient for subsequent maintenance and wiring harness inspection. At the same time, the positioning rod 502 and the side rod 501 are made of rubber. The second type of locator 5 consists only of side rods 501 symmetrically arranged on the top edge of the extension 4. The symmetrically distributed side rods 501 restrict the direction of the distribution of the automotive wiring harness. The damping element 6 is fixed to the top of the side rods 501. The automotive wiring harness is guided by the side rods 501 and the extension 4 with the above-mentioned movement control. This method reduces production costs, but it cannot perform additional tightness adjustment and stable guidance control of the automotive wiring harness on the extension 4.

[0025] In the above scheme, the damping component 6 can be set as a damping brush, a rubber damping strip, or an elastic rubber bladder, which facilitates the installation of automotive wiring harnesses. By utilizing the flexible damping of rubber, the automotive wiring harness is less likely to detach due to the location of the damping component 6 during long-term use.

[0026] Adopting such Figure 7 and Figure 8 As shown, in addition to the above technical solution, the present invention also discloses another usable embodiment, as follows: The positioning frame 1 and the bottom of the extension 4 are also equipped with a fastening adjuster to replace the extension strip 7; the fastening adjuster includes a rotating part 8 that is rotatably mounted through the end of the positioning frame 1, and a movable part 10 that is rotatably mounted at the center of the bottom of the extension 4, wherein one end of the tension tube 9 is rotatably mounted through the lower end of the rotating part 8, and the other end of the tension tube 9 is connected to the interior of the movable part 10 through a flexible rubber tube 11; at the same time, the movable parts 10 at the bottom of adjacent extensions 4 are also connected to each other through the tension tube 9 and the flexible rubber tube 11; This solution aims to eliminate the vibration caused by the inherent toughness of the extension strip 7 during installation and deformation. In other words, the excellent extensibility and flexibility of the extension strip 7 can cause oscillations at the location of the extension section 4 after long-term use following the guiding and positioning of the automotive wiring harness. This affects the wiring harness distribution and the frequency of oscillation friction. To address this, a new fastening adjuster is provided to adjust the positioning of the extension section 4, reducing its stability after adjustment, allowing for selective market use. Specifically, in this solution, adjacent extension sections 4 can only have their positions adjusted within their respective planes, allowing the "I"-shaped distribution of the extension sections 4 to be changed to an "S"-shaped distribution, suitable for guiding and positioning automotive wiring harnesses in areas with ample space. When adjusting the position of the extension 4, the positioning state between the extension 4 is adjusted by rotating the rotating part 8 and the movable part 10. Simultaneously, the planar alignment of the regular polygonal joints between the elastic damping rings 401 and the magnetic attraction between the permanent magnets achieve the positioning effect of the extension 4. The difference lies in that in this solution, the rotating part 8 and the stretching tube 9 form a relatively telescopic structure, and an elastic element 901 is provided at their through-connection. Furthermore, the rotating part 8 is internally connected to the stretching tube 9, the flexible hose 11, and the movable part 10, and the positioning is achieved through internal glue injection into the rotating part 8. The positioning and fastening mechanism, with the elastic element 901 providing stable convergence between adjacent extensions 4, allows positioning adhesive to be introduced into the rotating element 8 through the opening of the rubber plug 801 at the top of the rotating element 8. The adhesive is introduced and cured through the internal connection between the rotating element 8 and the tension tube 9, flexible tube 11, and movable element 10. After final curing, the extensions 4 are stably positioned, preventing rigid breakage. This also facilitates the guidance and positioning protection of automotive wiring harnesses, making it suitable for preventing detachment, guiding, and positioning automotive wiring harnesses in auxiliary environments.

[0027] Example 2: Based on Example 1, this solution further optimizes the shape of the extension 4. For example, the extension 4 is set as a rectangular structure in the middle and a round shape at the end to expand the rotation angle between adjacent extensions 4. At the same time, adjacent extensions 4 and the extension 4 and the positioning frame 1 are elastically connected by elastic damping rings 401, which makes it more convenient for guiding and positioning control of automotive wiring harnesses. It is suitable for large vehicles and is used for guiding and positioning control of automotive wiring harnesses in vehicles.

[0028] In the above solution, the automotive wiring harness guide bracket is not only suitable for small and medium-sized vehicles, but also for large vehicles such as trailers, for guiding and positioning automotive wiring harnesses to prevent them from detaching.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
