Description

Technical Field

[0001] This application relates to the field of automotive parts technology, specifically a guide harness bracket. Background Technology

[0002] In the automotive manufacturing industry, the contact area between the main wiring harness at the rear of the fuse box and the body crossbeam is a known high-risk area for failure. The reasons are as follows: continuous vibrations occur during vehicle operation, causing repeated friction between the wiring harness and the metal crossbeam. Prolonged friction leads to wear on the outer sheath of the wiring harness, wire breakage, and a series of other problems, which can cause abnormal signal transmission or even short circuits and fires.

[0003] To address this issue, automakers have adopted various methods, such as using plastic corrugated tubing over the wire harness and attaching it to the crossbeam with foam tape to prevent direct friction between the harness and the vehicle body, or using dedicated metal brackets to support the harness. However, the tape is prone to aging and detachment after prolonged use or at high temperatures; metal brackets are heavy, and the hard contact between the metal and the harness also poses a risk of wire harness wear. Summary of the Invention

[0004] To address the aforementioned issues, this application proposes a guiding wire harness bracket.

[0005] A guiding wire harness bracket includes a bracket body and a cable tie that cooperates with it. The bracket body includes a receiving portion for isolating the wire harness. The receiving portion includes a first receiving portion and a second receiving portion. The center lines of the second receiving portion and the first receiving portion form an angle of 0° to 90°. The bracket body also includes a transition section for connecting the first receiving portion and the second receiving portion. The curvature of the transition section matches the angle between the first receiving portion and the second receiving portion, forming a guiding path. This allows the wire harness to bend naturally and transition smoothly, avoiding stress concentration at the bend point caused by hard bending, which leads to wear. At the same time, it restricts the freedom of the cable, limits the lateral displacement of the wire harness during vibration, and reduces friction with the vehicle body.

[0006] Furthermore, it also includes arc-shaped parts that are fixedly connected to both sides of the receiving part. The thickness of the arc-shaped parts increases gradually from the bottom to the top to enhance the structural strength and resist vibration deformation.

[0007] Furthermore, the arc-shaped portion includes a first arc-shaped portion and a second arc-shaped portion, which are fixedly connected by a transition section. The arc-shaped portion surrounds the wire harness from both sides, restricting the swing of the wire harness.

[0008] Furthermore, it also includes a fixing ear piece, which includes a first fixing ear piece and a second fixing ear piece that are fixedly connected to the top ends of the first arc-shaped portion and the second arc-shaped portion to prevent the wire harness from coming out;

[0009] Furthermore, it also includes a third fixing lug that is fixedly connected to the top of the transition section. The third fixing lug connects the first fixing lug and the second fixing lug. The curvature of the third fixing lug corresponds to the curvature of the transition section, so as to prevent the wire harness from being squeezed and worn at the bend.

[0010] Furthermore, the ratio of the thickness of the receiving part to the thickness of the bottom of the arc-shaped part is 1.8 to 2.2; the thicker plate-shaped part can provide a stable bearing surface and disperse the downward pressure of the wire bundle, while the thinner arc-shaped part is beneficial to reducing the overall weight of the support.

[0011] Furthermore, the thickness of the fixing ear is less than the thickness of the top of the arc-shaped portion, and the ratio of the thickness of the fixing ear to the thickness of the top of the arc-shaped portion is 1.3 to 1.6; the thinner ear can avoid excessive weight increase while ensuring flexibility and reducing hard contact.

[0012] Furthermore, the surface of the arc-shaped part is provided with cable tie fixing holes. The cable ties pass through the cable tie fixing holes to fix the bracket and the wire harness, replacing the tape, avoiding the risk of aging and falling off, and at the same time facilitating quick replacement later.

[0013] Furthermore, the receiving part is a flat or slightly curved panel with a width of at least 1.5 times the diameter of the wire harness, increasing the area within a reasonable range to further reduce pressure. The surface of the receiving part is provided with anti-slip texture, and the bottom surface of the receiving part is provided with anti-slip strips.

[0014] When in use, wrap the bracket body around the main wiring harness of the car, so that the wiring harness fits against the plate-shaped part, and use cable ties to pass through the cable tie holes on the arc-shaped parts on both sides to apply radial preload; finally, position the assembled bracket assembly to the contact surface of the car body crossbeam.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] The system employs a first and second receiving section with an included angle of 0° to 90°, combined with a transition section that matches the curvature to form a natural guiding path. This, along with the arc-shaped section on both sides that thickens gradually to wrap the wire harness, significantly restricts the degree of freedom of the wire harness and prevents it from rubbing hard against the vehicle body beam. The binding holes and fixing lugs work together to form a constraint frame, further reducing the risk of wire harness detachment. The gradient design of the arc-shaped section, which is thin at the bottom and thick at the top, achieves structural weight reduction. At the same time, the receiving section is widened, and anti-slip textures and anti-slip strips on the bottom surface are added to increase the contact area and distribute pressure, allowing the wire harness to make flexible contact with the bracket and suppressing wear from the source.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-8As shown, a guide harness bracket includes a bracket body and a cable tie that cooperates with it. The bracket body includes a receiving portion for isolating the harness. The receiving portion includes a first receiving portion 101 and a second receiving portion 102. The center lines of the second receiving portion 102 and the first receiving portion 101 form an angle of 0° to 90°. The bracket also includes a transition section 4 for connecting the first receiving portion 101 and the second receiving portion 102. The curvature of the transition section 4 matches the angle between the first receiving portion 101 and the second receiving portion 102, forming a guide path that allows the harness to bend naturally, avoiding stress concentration at the bend and wear caused by hard bending. At the same time, it restricts the freedom of the cable, limits the lateral displacement of the harness during vibration, and reduces friction with the vehicle body.

[0036] It also includes arc-shaped portions fixedly connected to both sides of the receiving part, the thickness of which gradually increases from the bottom to the top to enhance structural strength and resist vibration deformation;

[0037] The arc-shaped portion includes a first arc-shaped portion 201 and a second arc-shaped portion 202. The first arc-shaped portion 201 and the second arc-shaped portion 202 are fixedly connected by a transition section 4. The arc-shaped portion surrounds the wire harness from both sides, restricting the swing of the wire harness.

[0038] It also includes a fixing ear piece, which includes a first fixing ear piece 301 and a second fixing ear piece 302 that are fixedly connected to the top ends of the first arc-shaped portion 201 and the second arc-shaped portion 202 to prevent the wire harness from coming out;

[0039] It also includes a third fixing ear 303 that is fixedly connected to the top of the transition section 4. The third fixing ear 303 connects the first fixing ear 301 and the second fixing ear 302. The curvature of the third fixing ear 303 corresponds to the curvature of the transition section 4 to prevent the wire harness from being squeezed and worn at the bend.

[0040] The ratio of the thickness of the receiving part to the thickness of the bottom of the arc-shaped part is 1.8 to 2.2; the thicker plate-shaped part can provide a stable bearing surface and disperse the downward pressure of the wire bundle, while the thinner arc-shaped part is beneficial to reducing the overall weight of the support.

[0041] The thickness of the fixing ear is less than the thickness of the top of the arc-shaped portion, and the ratio of the thickness of the fixing ear to the thickness of the top of the arc-shaped portion is 1.3 to 1.6; the thinner ear can avoid excessive weight increase while ensuring flexibility and reducing hard contact.

[0042] The arc-shaped part has cable tie fixing holes 6. The cable ties pass through the cable tie fixing holes 6 to fix the bracket and the wire harness, replacing the tape, avoiding the risk of aging and falling off, and facilitating quick replacement later.

[0043] The receiving part is a flat or slightly curved panel with a width of at least 1.5 times the diameter of the wire harness. The area is increased within a reasonable range to further reduce the pressure. The surface of the receiving part is provided with anti-slip texture, and the bottom surface of the receiving part is provided with anti-slip strip 5.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
