Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an automotive wiring harness bracket. Background Technology

[0002] As an indispensable component in automotive electronic and electrical systems, the performance and design of automotive wiring harness brackets have a significant impact on the installation positioning, assembly efficiency, and stability of the entire vehicle's electronic and electrical systems. With the continuous development of the automotive industry, people's demands for vehicle comfort, safety, and intelligence are increasing, leading to a corresponding increase in the complexity of automotive electronic and electrical systems. This places higher demands on the function and performance of wiring harness brackets.

[0003] In existing wiring harness bracket technologies, such as "A Novel Automotive Wiring Harness Bracket" (application number: 201720883778.0), a bracket body with an elongated structure is disclosed. The bracket body has multiple slots for the wiring harness to pass through. Multiple extensions with mounting holes are provided on the rear side of the bracket body. Multiple first snap-fit ​​members are provided on the front side of the bracket body. Each first snap-fit ​​member includes a vertically arranged snap-fit ​​groove on the left and right sides. Second snap-fit ​​members are provided on both the front and rear side walls of the bracket body. Each second snap-fit ​​member includes a buckle at the bottom.

[0004] However, there is still room for improvement in the design of existing wiring harness brackets. With the increasing number of connectors in automotive electronic and electrical systems, higher demands are placed on the connector installation capabilities of wiring harness brackets. However, since most existing brackets use a fully enclosed structure to confine the wiring harness, while providing good protection, it increases material costs. A fully enclosed structure requires more material to construct the complete protective space, which leads to increased costs in mass production. If a simple slot design is used instead of a fully enclosed structure, the wiring harness may not receive sufficient protection. Utility Model Content

[0005] The technical problem to be solved by this application is to provide an automotive wiring harness bracket that, through a semi-enclosed protective barrier structure, reduces material and production costs, simplifies the wiring harness assembly process, and improves assembly efficiency.

[0006] The technical solution adopted in this application is as follows: an automotive wiring harness bracket, comprising a bracket body with an elongated structure, wherein the bracket body extends downward to form a first side guard, a second side guard, and a third side guard, the first side guard, the second side guard, and the third side guard are spaced apart, the second side guard is located between the first side guard and the third side guard, the first side guard and the second side guard form a mounting groove for the wiring harness to pass through, the second side guard and the third side guard form a mounting groove for the wiring harness to pass through, a first protective rail extends from the bottom of a portion of the second side guard towards the first side guard, a second protective rail extends from the bottom of a portion of the second side guard towards the first side guard, snap-fit ​​members are provided on the upper and lower end faces of the bracket body and the outer side of the third side guard, and plug-in members are provided on the bracket body, the first side guard, the second side guard, and the third side guard.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, the bottom portion of the wire harness bracket extends towards the first side edge from the second side edge, forming a first and second protective railing, thus creating a semi-enclosed protective structure. This design reduces material costs compared to a fully enclosed structure. While a fully enclosed structure offers excellent protection, it requires more material to construct the surrounding protection. The semi-enclosed protective railings, however, also provide some protection, preventing excessive compression or impact on the wire harness within the mounting groove, while simultaneously saving material and reducing production costs.

[0008] Secondly, due to the semi-enclosed protective barrier structure, the entire wire harness does not require drilling. In some traditional wire harness bracket designs, the wire harness may need to be threaded through holes for fixation, which is cumbersome during assembly and prone to problems such as difficulty in drilling and wire harness wear. This design simplifies the wire harness assembly process; the wire harness can simply be placed in the mounting groove formed by the first and second side guards, the second side guard, and the third side guard, thus improving assembly efficiency.

[0009] Finally, the elongated support body extends downwards with multiple side guards, which cooperate with the support body, connectors, snap-fit ​​components, and other structures to form a highly integrated support. This structural design allows the support to better distribute stress when subjected to external forces (such as the tension of the wiring harness or vibrations during vehicle operation), thereby improving the support's load-bearing capacity and durability.

[0010] In this application, for ease of description, the figures in the specification are used as references. Figure 1 Using the top and bottom and front and back as a reference does not imply the product's orientation in actual application.

[0011] In some embodiments of this application, an arc-shaped groove is provided on the outer side of the bottom of the first side guard, and an arc-shaped guard extends outward from the top surface of the arc-shaped groove. The arc-shaped guard and the inner wall surface of the arc-shaped groove form a semi-circular wire harness protection space.

[0012] This arc-shaped structure design reduces the contact between the wire harness and other components in the environment without adding new accessories, thereby better protecting the wire harness, avoiding external wear and interference, and improving the service life and reliability of the wire harness.

[0013] In some embodiments of this application, a third protective rail extends from the bottom of a portion of the third side guard towards the direction of the second side guard, and the first and second protective rails respectively cover a portion of the side length of the second side guard, and the third protective rail covers a portion of the side length of the second side guard.

[0014] The addition of a third protective barrier further enhances the protection of the wire harness. This prevents excessive pressure or impact on the harness within the mounting slot, improving its stability and safety.

[0015] Specifically, the first and second guardrails cover 1 / 3 to 2 / 3 of the length of the second side guardrail. The third guardrail covers 1 / 3 to 2 / 3 of the length of the second side guardrail.

[0016] In some embodiments of this application, a fastener is provided on the outer side of the first side stop, and the axial direction of the fastener is perpendicular to the outer side of the first side stop; a mounting plate is provided above the third side stop, and a mounting hole is provided on the mounting plate, and the axial direction of the mounting hole is parallel to the third side stop.

[0017] This design changes the installation direction of existing technology. By using two perpendicular fixing methods, the force on the clips is reduced, preventing axial detachment. This extends the service life of the wire harness bracket and improves its stability and reliability.

[0018] In some embodiments of this application, a reinforcing plate is provided between the mounting plate and the third side flange, and an inverted L-shaped baffle is provided on the side of the mounting plate near the third side flange. The L-shaped baffle and the top surface of the bracket body form a rectangular channel.

[0019] The design of the reinforcing plate and L-shaped baffle enhances the structural strength between the mounting plate and the third side flange, improving the overall stability of the bracket. Simultaneously, the rectangular channel formed by the L-shaped baffle and the top surface of the bracket body better guides and secures the wiring harness or other components, improving assembly accuracy and stability.

[0020] In some embodiments of this application, the front and rear sides of the bracket body, the first side stop, the second side stop, and the third side stop are all provided with weight-reducing grooves.

[0021] The weight-reducing groove in this application is aligned with the mold draft direction, eliminating the need for additional sliders. This reduces mold complexity and cost, while simultaneously reducing the weight of the support frame while maintaining its strength, thus improving material utilization.

[0022] In some embodiments of this application, the front side of the bracket body is provided with a plurality of snap-fit ​​slots, the outer side of the snap-fit ​​slots is open, the snap-fit ​​member is arranged on the outer side of the snap-fit ​​slots, the inner side of the snap-fit ​​slots is provided with an opening adapted to the width of the snap-fit ​​member, and the outer side and the inner side of the snap-fit ​​slots are two sides arranged opposite to each other.

[0023] This design makes the installation and removal of snap-fit ​​components easier, improving assembly efficiency. At the same time, the openings on the inner and outer sides of the snap-fit ​​slot better secure the snap-fit ​​component, enhancing its stability and reliability.

[0024] In some embodiments of this application, a reinforcing rib is provided in the middle of the inner side of the snap-fit ​​member, and reinforcing ridges extend outward from both sides of the snap-fit ​​member; multiple snap-fit ​​members face the same direction.

[0025] By employing a single-sided guiding matching structure and appropriately adding reinforcing ribs and edges at the snap-fit ​​points, the strength of the bracket can be guaranteed even under single-sided assembly, preventing the bracket assembly structure from breaking. This improves the durability and reliability of the snap-fit ​​components and extends the service life of the bracket.

[0026] In some embodiments of this application, the connector is a plate-shaped structural member, and the surface of the connector is provided with undercuts.

[0027] The plate-like connector surface features inverted clips for better installation and to prevent loosening or detachment during use. This improves the stability and reliability of the connector, ensuring the stability of the wire harness connection.

[0028] In some embodiments of this application, at least one of the plurality of connectors is arranged in the opposite direction to the others.

[0029] This design allows for the installation of more connectors within the same bracket length, or a shorter bracket to accommodate the same number of connectors. This improves the bracket's space utilization, adapts to the compact installation environment inside a vehicle, and meets the connection requirements of complex wiring in automotive electronic and electrical systems.

[0034] The present application will now be described in detail with reference to the accompanying drawings.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] An automotive wiring harness bracket, as described in Embodiment 1 Figures 1 to 3As shown, the device includes a long, narrow support body 1. The support body 1 extends downwards to form a first side guard 2, a second side guard 3, and a third side guard 4. These three side guards are spaced apart, with the second side guard 3 located between the first and third side guards 2 and 4. The first and second side guards 2 and 3 form a mounting groove for the wire harness to pass through. A first protective rail 6 extends from the bottom of a portion of the second side guard towards the first side guard 2, and a second protective rail 7 extends from the bottom of another portion of the second side guard towards the first side guard 2. The wire harness support, with the first and second protective rails 6 and 7 extending from the bottom of a portion of the second side guard 3 towards the first side guard 2, forms a semi-enclosed protective structure. This design reduces material costs compared to a fully enclosed structure. While a fully enclosed structure offers excellent protection, it requires more material to construct the surrounding protection. The semi-enclosed guardrail can also provide protection to a certain extent, preventing the wire harness from being excessively squeezed or bumped by the outside in the installation groove, while saving materials and reducing production costs.

[0037] Because of its semi-enclosed protective barrier structure, the entire wire harness does not require drilling. In some traditional wire harness bracket designs, the wire harness may need to be threaded through holes for fixation, which is cumbersome during assembly and prone to problems such as difficulty in drilling and wire harness wear. This design simplifies the wire harness assembly process; the wire harness can simply be placed in the mounting groove formed by the first side guard 2, the second side guard 3, the third side guard 4, and the fourth side guard 4, thus improving assembly efficiency.

[0038] The upper and lower end faces of the bracket body 1 and the outer side of the third side flange 4 are all provided with snap-fit ​​members 8. The bracket body 1, the first side flange 2, the second side flange 3, and the third side flange 4 are all provided with plug-in members 9. In this application, the elongated bracket body 1 extends downwards with multiple side flanges, and these side flanges cooperate with the bracket body 1, the plug-in members 9, the snap-fit ​​members 8, and other structures to form a highly integrated bracket. This structural design allows the bracket to better distribute stress when subjected to external forces (such as the tension of the wiring harness, vibration during vehicle operation, etc.), thereby improving the bracket's load-bearing capacity and durability.

[0039] In this application, for ease of description, the figures in the specification are used as references. Figure 1 Using the top and bottom and front and back as a reference does not imply the product's orientation in actual application.

[0040] Example 2, as Figures 1 to 3As shown, an arc-shaped groove 10 is formed on the outer side of the bottom of the first side guard 2. An arc-shaped guard 11 extends outward from the top surface of the arc-shaped groove 10. The arc-shaped guard 11, together with the inner wall of the arc-shaped groove 10, forms a semi-circular wire harness protection space. This arc-shaped structure design can reduce the contact between the wire harness and other components in the environment without adding new components, thereby better protecting the wire harness, avoiding external wear and interference, and improving the service life and reliability of the wire harness.

[0041] The bottom portion of the third side guard extends towards the second side guard 3 to form a third protective rail 12. The first protective rail 6 and the second protective rail 7 respectively cover a portion of the side length of the second side guard, and the third protective rail 12 also covers a portion of the side length of the second side guard. By adding the third protective rail 12, the protective performance of the wire harness is further enhanced. This prevents the wire harness from being excessively squeezed or impacted by external forces within the mounting groove, improving the stability and safety of the wire harness.

[0042] Specifically, the first guardrail 6 and the second guardrail 7 cover 1 / 3 to 2 / 3 of the length of the second side guardrail. The third guardrail 12 covers 1 / 3 to 2 / 3 of the length of the second side guardrail.

[0043] A latching element 13 is provided on the outer surface of the first side stop, and the axial direction of the latching element 13 is perpendicular to the outer surface of the first side stop. A mounting plate 14 is provided above the third side stop, and a mounting hole 15 is provided on the mounting plate 14, and the axial direction of the mounting hole 15 is parallel to the third side stop. This design changes the installation direction of the prior art. By fixing in two perpendicular directions, the force borne by the latch is reduced, and axial detachment is prevented. This extends the service life of the wire harness bracket and improves the stability and reliability of the bracket.

[0044] A reinforcing plate 16 is provided between the mounting plate 14 and the third side flange. An inverted L-shaped baffle 17 is provided on the side of the mounting plate 14 closest to the third side flange. The L-shaped baffle 17 and the top surface of the bracket body 1 form a rectangular channel. The design of the reinforcing plate 16 and the L-shaped baffle 17 enhances the structural strength between the mounting plate 14 and the third side flange, improving the overall stability of the bracket. At the same time, the rectangular channel formed by the L-shaped baffle 17 and the top surface of the bracket body 1 can better guide and fix the wire harness or other components, improving the accuracy and stability of assembly.

[0045] Weight-reducing grooves 19 are evenly distributed on the front and rear sides of the bracket body 1, the first side stop 2, the second side stop 3, and the third side stop 4. In this application, the weight-reducing grooves 19 are aligned with the mold draft direction, eliminating the need for additional sliders. This reduces the complexity and cost of the mold, while simultaneously reducing the weight of the bracket and improving material utilization while maintaining its strength.

[0046] The front side of the bracket body 1 has multiple snap-fit ​​slots 20. The outer side of each snap-fit ​​slot 20 is open, and the snap-fit ​​component 8 is positioned on the outer side of the snap-fit ​​slot 20. The inner side of each snap-fit ​​slot 20 has an opening adapted to the width of the snap-fit ​​component 8. The outer and inner sides of the snap-fit ​​slot 20 are opposite to each other. This design makes the installation and removal of the snap-fit ​​component 8 more convenient, improving assembly efficiency. Simultaneously, the openings on the inner and outer sides of the snap-fit ​​slot 20 better secure the snap-fit ​​component 8, improving the stability and reliability of the snap-fit ​​connection.

[0047] A reinforcing rib 21 is provided in the middle of the inner side of the snap-fit ​​component 8, and reinforcing ridges 22 extend outward from both sides of the snap-fit ​​component 8; multiple snap-fit ​​components 8 face the same direction. By adopting a single-sided guiding matching structure and appropriately adding reinforcing ribs 21 and reinforcing ridges 22 at the snap-fit ​​position, the strength of the component can be guaranteed even under single-sided assembly, preventing the bracket assembly structure from breaking. This improves the durability and reliability of the snap-fit ​​component 8 and extends the service life of the bracket.

[0048] The connector 9 is a plate-shaped structure with buckles 23 on its surface. These buckles allow for better installation and prevent the connector 9 from loosening or falling off during use. This improves the stability and reliability of the connector 9, ensuring the stability of the wire harness connection.

[0049] At least one of the multiple connectors 9 is oriented opposite to the others. This design allows for the installation of more connectors 9 on a bracket of the same length, or for a shorter bracket to accommodate the same number of connectors 9. This improves the space utilization of the bracket, adapts to the compact installation environment inside a vehicle, and meets the connection requirements of complex wiring in automotive electronic and electrical systems.

[0050] The rest of the contents of Example 2 are the same as those of Example 1.

[0051] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
