Description

Technical Field

[0001] This utility model relates to the technical field of automotive wiring harness fixing devices, and in particular to a wiring harness bracket suitable for flat wiring. Background Technology

[0002] In automobile manufacturing, the arrangement of wiring harnesses is a critical process, and its rationality directly affects the assembly efficiency and safety of the vehicle. Traditional automotive wiring harnesses use tape to bind the wires into bundles, forming cylindrical bundles, which are then fixed to equipment or the vehicle body with cable ties.

[0003] While this traditional process is highly mature, it suffers from several insurmountable drawbacks. First, the cylindrical shape of the wiring harness results in a large outer diameter, leading to extremely poor flexibility when wiring in the limited space of a car's interior. Second, its protective performance is generally poor; the bundled wiring harness cannot be punctured by sharp objects, squeezed, or stepped on, otherwise it is easily damaged. Third, it is particularly unsuitable for scenarios requiring flat wiring, such as wiring harnesses above the headliner and under the carpet, as the cylindrical shape will lift the headliner and carpet, affecting the flatness and aesthetics of the car's interior trim. Furthermore, traditional wiring harnesses struggle to easily achieve stable connections between the vehicle's wiring harness and specialized harnesses such as sunroof, seat, and fuel tank harnesses, and it is difficult to avoid moving parts during wiring, easily leading to interference between the harness and components.

[0004] In addition, traditional fixing methods rely heavily on bolts for fastening, which can easily break or wear down the wiring harness during the fastening process. Furthermore, the brackets are mostly non-removable structures, which are easily damaged after being disassembled once and cannot be reused, increasing the cost of use. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wire harness bracket suitable for flat wiring. This bracket addresses the technical problems of traditional automotive wire harnesses, such as large outer diameter, limited wiring scenarios, poor protection performance, easy interference with components, inconvenient assembly and disassembly, and easy damage to the wire harness when tightening bolts. It enables flexible wiring in special scenarios such as long and narrow gaps, above car headliners, and under carpets, enhances wire harness protection, prevents wire harness damage, improves the bracket's reusability, and reduces usage costs.

[0006] The above objectives are achieved through the following technical solutions: A wire harness bracket suitable for flat cabling includes a bracket body with a hollow wire channel cavity for accommodating and protecting the wire harness, while providing a stable arrangement space for the wire harness. At least one outwardly extending guide seat is provided at each end of the wire channel cavity, which guides the wire harness to enter and exit, ensuring smooth wire harness cabling. The guide seat has a wire groove communicating with the wire channel cavity. After the wire harness enters the wire channel cavity from either end of the wire groove, it is led out through the wire groove at the other end.

[0007] Furthermore, the wire groove is an open groove with its opening facing upwards. The wire groove includes a bottom edge and wire groove side edges symmetrically arranged on both sides of the bottom edge and perpendicular to the bottom edge. The bottom surface of the bottom edge of the wire groove is level with the bottom surface of the support body, and the upper surface of the bottom edge of the wire groove is level with the bottom wall of the wire groove cavity. This structural design can ensure that the wire harness transitions smoothly in the wire groove and the wire groove cavity, avoiding bending damage to the wire harness.

[0008] Furthermore, the inner ends of the two sides of the same wire groove abut against the port of the wire groove cavity to form an inlet and outlet. A heat dissipation port is formed between the outer side of any wire groove and the port of the wire groove cavity. This heat dissipation port can facilitate the rapid dissipation of the high temperature generated in the wire groove cavity when the high current wire harness is working, thus ensuring the stability of the wire harness operation.

[0009] Furthermore, a cable tie hole is provided on the side of the wire channel. The cable tie hole is used to fix the wire bundle in the wire channel with a cable tie to prevent the wire bundle from falling out of the wire channel during use, thereby further improving the stability of the wire bundle arrangement.

[0010] Furthermore, the guide seat and the bracket body are integrally formed, and both the guide seat and the bracket body are made of plastic material; the integral forming process can ensure the stability and firmness of the overall structure of the bracket, while the plastic material takes into account the mechanical strength and manufacturing cost of the bracket, making it easy to mass-produce.

[0011] Furthermore, the length of the wire channel does not exceed 30mm, the height of the wire channel does not exceed the height of the bracket body, and the width of the wire channel does not exceed the width of the bracket body. This size limitation ensures that the wire channel and the bracket body have a compact structure and do not occupy too much extra space.

[0012] Furthermore, the bracket body has a straight, flat shape, and the thickness of the bracket body does not exceed 10mm; the flat shape allows the bracket to adapt to special wiring spaces such as long and narrow gaps, greatly improving the utilization rate of the car's interior space.

[0013] Furthermore, the bottom surface of the bracket body is provided with a detachable buckle. The buckle is used with a round hole or an oblong hole to fix the bracket body to the external support, thereby controlling the wiring harness routing. The detachable design makes it easy to remove the buckle from the bracket body separately, avoiding the problem of the bracket being damaged after being disassembled once.

[0014] Furthermore, the wiring harness adapted to the bracket body is flat in shape, matching the flat shape of the bracket, which further optimizes the wiring effect.

[0015] Furthermore, the bracket body does not have bolt holes. This design can effectively prevent the wire harness from being crushed or worn when tightening bolts, thus avoiding the risk of wire harness damage caused by traditional bolt fixing methods from the root.

[0016] This utility model provides a wire harness bracket suitable for flat cabling, which allows for flexible cabling in scenarios such as long and narrow gaps, improving space utilization, protecting the wire harness, providing good heat dissipation, and featuring detachable clips for easy reuse. It also boasts a simple structure, low cost, and avoids damage to the wire harness caused by bolts. It offers the following advantages: 1. Significantly improved space utilization: The bracket body adopts a straight and flat design with a thickness of no more than 10mm. The compatible wiring harness is also flat, which can easily carry out wiring in special scenarios such as long and narrow gaps, above the car roof, and under the carpet. At the same time, it facilitates the connection between the whole vehicle wiring harness and special wiring harnesses such as sunroof wiring harness, seat wiring harness, and fuel tank wiring harness, without having to deliberately bypass wiring obstacle areas.

[0017] 2. Enhanced protection for wire harnesses: The wire harness is placed in a wire groove cavity with a certain mechanical strength, which can effectively prevent damage caused by sharp objects puncturing, squeezing, or stepping on it; the bracket body does not have bolt holes, which completely eliminates the possibility of the wire harness being crushed or worn when tightening bolts, and the wire harness in the wire groove can be fixed with cable ties through the cable tie holes to prevent the wire harness from coming off.

[0018] 3. Optimized heat dissipation performance and wiring stability: The heat dissipation vents formed by the outer side of the wire channel and the port of the wire channel cavity can quickly dissipate the high temperature generated by the high current wire harness operation, ensuring the stable operation of the wire harness; the guiding role of the guide seat and the fixing role of the buckle on the bracket make the wire harness routing controlled and prevent interference with the moving areas of surrounding components.

[0019] 4. High reusability and cost control: The detachable buckle design allows the bracket to be repeatedly disassembled and used, reducing the cost of use; the overall structure of the bracket is simple, the guide seat and the bracket body are integrally molded, made of plastic, the mold structure is simplified, the production process is simple, the cost is easy to control, and it is suitable for mass production.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] This solution provides a wire harness bracket suitable for flat cabling, including a bracket body 1. The bracket body 1 is a straight, flat plastic component with a thickness strictly controlled within 10mm. This thickness design ensures that the bracket can be easily embedded into narrow spaces such as long and narrow gaps in automobiles, without affecting the installation and movement of surrounding components.

[0024] like Figures 1-3 As shown, the bracket body 1 has a hollow wire groove cavity 2 inside. The size of the wire groove cavity 2 is set according to the specifications of the compatible flat wire harness, which can fully accommodate the wire harness and provide it with sufficient protective space to prevent the wire harness from being squeezed and deformed inside the cavity. At each end of the wire groove cavity 2, there is an outwardly extending guide seat 3 integrally formed. The guide seat 3 is also made of plastic. The integral structure with the bracket body 1 ensures the firmness of the connection between the two and prevents breakage and detachment during use.

[0025] like Figure 1 and Figure 2As shown, each guide seat 3 has a wire groove 4, which is fully connected to the wire groove cavity 2, forming a complete channel for the wire harness to enter and exit. The wire groove 4 is an open groove with its opening facing upwards, consisting of a bottom edge 5 and two side edges 6. The side edges 6 are symmetrically and vertically arranged on both sides of the bottom edge 5, and the bottom surface of the bottom edge 5 is level with the bottom surface of the support body 1, while the upper surface is level with the bottom wall of the wire groove cavity 2. This structure allows the wire harness to smoothly transition from the wire groove 4 into the wire groove cavity 2 without causing excessive bending angles, effectively protecting the wire harness sheath and internal wires.

[0026] like Figure 1 and Figure 2 As shown, the inner ends of the two wire groove sides 6 of the same wire groove 4 are tightly abutted against the port of the wire groove cavity 2, forming the wire inlet and outlet 7. The wire harness shuttles between the wire groove 4 and the wire groove cavity 2 through the wire inlet and outlet 7. Meanwhile, the outer side of the wire groove side 6 and the port of the wire groove cavity 2 naturally form a heat dissipation port 8. When the high current wire harness generates high temperature during operation, the heat will be quickly dissipated to the outside through the heat dissipation port 8, avoiding the excessive temperature inside the wire groove cavity 2 from affecting the conductivity and service life of the wire harness.

[0027] like Figure 1 and Figure 2 As shown, cable tie holes 9 are also machined on the side 6 of the wire trough. After the wire harness is arranged in the wire trough 4, the cable tie can be passed through the cable tie hole 9 and tightened to firmly fix the wire harness in the wire trough 4, preventing the wire harness from coming off the wire trough 4 due to bumps during vehicle operation and ensuring the stability of the wiring. In this embodiment, the length of the wire trough 4 is set to 30mm, and its height and width do not exceed the height and width of the bracket body 1, so that the wire trough 4 and the bracket body 1 form a compact integral structure without occupying additional space.

[0028] like Figure 2 As shown, a detachable clip 10 is installed on the bottom surface of the bracket body 1. The clip 10 is made of plastic material that is compatible with the bracket body 1 and can be used with round or oval holes on automobiles to quickly fix the bracket to external support components such as the vehicle body, thereby precisely controlling the routing direction of the wiring harness. When it is necessary to disassemble or adjust the position of the bracket, the clip 10 can be removed from the bracket body 1 separately, avoiding the problem of easy damage after disassembly of traditional brackets and realizing the reuse of the bracket.

[0029] It is particularly noteworthy that the bracket body 1 in this embodiment does not have any bolt holes, completely abandoning the traditional bolt fixing method and fundamentally solving the industry pain point of wire harness breakage or wear when tightening bolts. At the same time, the wire harness adapted to this bracket is flat in shape, perfectly matching the flat design of the bracket, further improving the fit and aesthetics of the wiring. This is especially suitable for scenarios requiring concealed wiring, such as above car headliners or under carpets, effectively avoiding the problem of traditional cylindrical wire harnesses lifting up the headliner or carpet.

[0030] The fixed bracket in this embodiment has a simple and reasonable structure. Through multiple structural designs such as flat shape, wire groove cavity protection, detachable buckle, and heat dissipation vent, it comprehensively solves many defects of traditional wire harness arrangement and has extremely high practical value and promotion prospects.

[0031] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
