Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness protection technology, and in particular to a door wiring harness sleeve for automobiles. Background Technology

[0002] In automotive low-voltage wiring harness layouts, the wiring harnesses between the body side panel and the door side are typically connected using rubber sleeves to prevent exposed wires and breakage due to stress during door opening and closing. In existing technology, especially in models with large tailgate opening angles (e.g., 270°), the wiring harness sleeves are often corrugated tubular structures, which are quite long and prone to getting caught between the tailgate and taillights during tailgate opening and closing, posing a risk of wire entrapment. To address this issue, existing solutions typically involve increasing the rigidity of the sleeves or increasing the space between the taillights and the tailgate sealing strip; however, the former increases assembly difficulty, while the latter increases manufacturing costs. Utility Model Content

[0003] The purpose of this utility model is to provide a door wiring harness sleeve for automobiles to solve the problem that existing low-voltage wiring harness sleeves for automobiles are easily trapped between the tailgate and the taillight.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A door wiring harness sleeve for vehicles includes: a first mounting base, a second mounting base, and a protective tube assembly. Both ends of the protective tube assembly are connected to the first mounting base and the second mounting base, respectively. The first mounting base is for mounting on a vehicle body; the second mounting base is for mounting on a vehicle door. The protective tube assembly includes a first corrugated pipe, a straight pipe, and a second corrugated pipe connected thereto. The end of the first corrugated pipe is connected to the first mounting base; the second corrugated pipe is connected to the second mounting base. Reinforcing ribs are formed on the first corrugated pipe and / or the second corrugated pipe, and the reinforcing ribs extend along the axial direction of the first corrugated pipe and / or the second corrugated pipe.

[0005] Based on the above technical means, this utility model sets a straight pipe between two corrugated pipes and adopts a combination of "first corrugated pipe-straight pipe-second corrugated pipe". This effectively avoids the problem that the corrugated pipe is easily hooked or stuck by the edge of the taillight due to its own pleated structure during the opening and closing of the tailgate, and fundamentally reduces the risk of the rubber sleeve being sandwiched between the tailgate and the taillight.

[0006] Meanwhile, by setting axially extending reinforcing ribs on at least one corrugated pipe, this utility model locally enhances the rigidity and rebound stress of key parts of the protective pipe assembly without significantly increasing the overall hardness of the rubber sleeve. This allows the protective pipe assembly to deviate from the taillight edge by its own stress, further avoiding the trapping of the line.

[0007] Furthermore, the protective pipe assembly also includes a first guide pipe, which has an arc-shaped curved structure. The first guide pipe is installed between the first mounting base and the first corrugated pipe and is connected to the first mounting base and the first corrugated pipe.

[0008] Based on the aforementioned technical means, the arc-shaped first guide tube provides a pre-set, smoothly transitioning bending path for the wiring harness sleeve during the opening and closing of the tailgate, which can guide the entire protective tube assembly to move along the expected trajectory and effectively avoid potential interference points such as the edge of the taillight.

[0009] Furthermore, the protective pipe assembly also includes a second guide pipe, which has an arc-shaped curved structure. The second guide pipe is installed between the second mounting base and the second corrugated pipe and is connected to the second mounting base and the second corrugated pipe.

[0010] Based on the above technical means, this utility model adds an arc-shaped second guide tube symmetrical to the side of the vehicle body on the side of the door, so that both ends of the entire protective tube assembly can achieve smooth and controllable directional bending during the opening and closing of the door, so as to guide the entire protective tube assembly to move along the expected trajectory and effectively avoid potential interference points such as the edge of the taillight.

[0011] Furthermore, the reinforcing ribs on the first corrugated pipe and / or the second corrugated pipe extend axially to a portion of the first guide pipe and / or a portion of the second guide pipe.

[0012] According to the above-mentioned technical means, the reinforcing rib gives the first guide tube or the second guide tube a certain stress, so that when the first guide tube or the second guide tube bends or twists during the opening and closing of the car door, it can automatically recover.

[0013] Furthermore, the number of reinforcing ribs is at least two, and each reinforcing rib is evenly distributed circumferentially along the first corrugated pipe and / or the second corrugated pipe.

[0014] According to the above technical means, when the rubber sleeve is deformed, twisted or squeezed by the surrounding components during the opening and closing of the tailgate, the multiple reinforcing ribs can not only provide rebound stress, but also provide radial support force to prevent the first or second corrugated tube from collapsing inward and maintain the safe space required for the wire harness inside the tube.

[0015] Furthermore, the protective tube assembly is a one-piece molded structure.

[0016] Based on the above technical means, the one-piece molding structure ensures that there are no splicing seams or connection interfaces between the various parts of the protective tube assembly, preventing moisture and dust from entering the tube body through these seams and damaging the wiring harness.

[0017] Furthermore, the installation direction of the first mounting base is arranged at 180° with the extension direction of the protective tube assembly.

[0018] Furthermore, a first snap-fit ​​cavity is formed on the first mounting base, which is used to snap-fit ​​with the vehicle body.

[0019] Based on the aforementioned technical means, the snap-fit ​​connection structure enables the first mounting bracket to be quickly installed on the vehicle body.

[0020] Furthermore, the angle between the installation direction of the second mounting base and the extension direction of the protective tube assembly is ≤30°.

[0021] According to the above technical means, the installation of the first mounting bracket and the installation of the second mounting bracket can increase the gap between the rubber sleeve and the edge of the taillight during the tailgate closing process, and prevent the wire from getting caught.

[0022] Furthermore, a second snap-fit ​​cavity is formed on the second mounting base, the second snap-fit ​​cavity being used to snap into the vehicle door.

[0023] Based on the aforementioned technical means, the snap-fit ​​connection structure enables the second mounting bracket to be quickly installed on the car door.

[0024] The beneficial effects achieved by this utility model are: This invention features a straight pipe between two corrugated pipes, employing a combination of "first corrugated pipe - straight pipe - second corrugated pipe". This effectively prevents the corrugated pipe from being easily hooked or stuck by the taillight edge due to its own pleated structure during the opening and closing of the tailgate, fundamentally reducing the risk of the rubber sleeve being trapped between the tailgate and the taillight.

[0025] Meanwhile, by setting axially extending reinforcing ribs on at least one corrugated pipe, this utility model locally enhances the rigidity and rebound stress of key parts of the protective pipe assembly without significantly increasing the overall hardness of the rubber sleeve. This allows the protective pipe assembly to deviate from the taillight edge by its own stress, further avoiding the trapping of the line. Attached Figure Description

[0034] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, a door wiring harness sleeve for vehicles includes: a first mounting base 1, a second mounting base 2, and a protective tube assembly 3. The two ends of the protective tube assembly 3 are respectively connected to the first mounting base 1 and the second mounting base 2. The first mounting base 1 is used for mounting on the vehicle body; the second mounting base 2 is used for mounting on the vehicle door. The protective tube assembly 3 includes a first corrugated pipe 31, a straight pipe 32, and a second corrugated pipe 33 connected thereto. The end of the first corrugated pipe 31 is connected to the first mounting base 1; the second corrugated pipe 33 is connected to the second mounting base 2. A reinforcing rib 34 is formed on the first corrugated pipe 31 and / or the second corrugated pipe 33, and the reinforcing rib 34 extends along the axial direction of the first corrugated pipe 31 and / or the second corrugated pipe 33.

[0036] In this embodiment, a straight pipe 32 is set between the two corrugated pipes, and a combination of "first corrugated pipe 31-straight pipe 32-second corrugated pipe 33" is adopted. This effectively avoids the problem that the corrugated pipe is easily hooked or stuck by the edge of the taillight due to its own pleated structure during the opening and closing of the tailgate, and fundamentally reduces the risk of the rubber sleeve being sandwiched between the tailgate and the taillight.

[0037] Meanwhile, this embodiment provides axially extending reinforcing ribs 34 on at least one bellows, thereby locally enhancing the rigidity and rebound stress of key parts of the protective tube assembly 3 without significantly increasing the overall hardness of the sleeve. This allows the protective tube assembly 3 to deviate from the taillight edge by its own stress, further avoiding the trapping of the line.

[0038] like Figure 1 and Figure 2 As shown, the protective pipe assembly 3 also includes a first guide pipe 35, which has an arc-shaped curved structure. The first guide pipe 35 is installed between the first mounting base 1 and the first corrugated pipe 31 and is connected to the first mounting base 1 and the first corrugated pipe 31.

[0039] The arc-shaped first guide tube 35 provides a pre-set, smoothly transitioning bending path for the wiring harness sleeve during the opening and closing of the tailgate, which can guide the entire protective tube assembly 3 to move along the expected trajectory and effectively avoid potential interference points such as the edge of the taillight.

[0040] like Figure 1 and Figure 2 As shown, the protective pipe assembly 3 also includes a second guide pipe 36, which has an arc-shaped curved structure. The second guide pipe 36 is installed between the second mounting base 2 and the second corrugated pipe 33 and is connected to the second mounting base 2 and the second corrugated pipe 33.

[0041] In this embodiment, by adding an arc-shaped second guide tube 36 symmetrical to the side of the vehicle body on the side of the door, the entire protective tube assembly 3 can achieve smooth and controllable directional bending at both ends during the opening and closing of the door, so as to guide the entire protective tube assembly 3 to move along the expected trajectory and effectively avoid potential interference points such as the edge of the taillight.

[0042] like Figure 1 and Figure 2 As shown, the reinforcing ribs 34 on the first corrugated pipe 31 and / or the second corrugated pipe 33 extend axially to a portion of the first guide pipe 35 and / or a portion of the second guide pipe 36.

[0043] The reinforcing rib 34 provides the first guide tube 35 or the second guide tube 36 with a certain stress, so that the first guide tube 35 or the second guide tube 36 can automatically recover after bending and twisting during the opening and closing of the car door.

[0044] In this embodiment, as Figure 1 and Figure 2 As shown, a reinforcing rib 34 is formed on the second corrugated pipe 33. The reinforcing rib 34 extends to a portion of the second guide pipe 36, but does not penetrate to the second mounting base 2, so as to form a one-sided, asymmetrical design.

[0045] The number of reinforcing ribs 34 is at least two, and each reinforcing rib 34 is evenly distributed circumferentially along the first corrugated pipe 31 and / or the second corrugated pipe 33.

[0046] When the rubber sleeve deforms, twists, or is squeezed by surrounding components during the opening and closing of the tailgate, the multiple reinforcing ribs 34 can not only provide rebound stress, but also provide radial support force to prevent the first corrugated tube 31 or the second corrugated tube 33 from collapsing inward and maintain the safe space required for the wire harness inside the tube.

[0047] In this embodiment, as Figure 2 As shown, two reinforcing ribs 34 are symmetrically distributed on the second corrugated pipe 33 to provide uniform stiffness and resilience stress.

[0048] In this embodiment, the protective tube assembly 3 is an integrally molded structure.

[0049] The one-piece molding structure eliminates the need for assembly seams or connection interfaces between the various parts of the protective tube assembly 3, preventing moisture and dust from entering the tube body through these seams and damaging the wiring harness.

[0050] like Figure 2 As shown, the installation direction of the first mounting base 1 is arranged at 180° with the extension direction of the protective tube assembly 3.

[0051] like Figure 4 As shown, a first snap-fit ​​cavity 11 is formed on the first mounting base 1, and the first snap-fit ​​cavity 11 is used to snap-fit ​​with the vehicle body.

[0052] This embodiment uses a snap-fit ​​connection structure to enable the first mounting base 1 to be quickly installed on the vehicle body.

[0053] In this embodiment, when installing the first mounting seat 1, simply insert the lower part of the first mounting seat 1 into the sheet metal hole of the vehicle body, press the upper part of the first mounting seat 1 until the sheet metal edge is engaged with the first snap-fit ​​cavity 11, and the interference fit of the upper and lower lips can achieve a firm lock and effectively prevent it from falling off, while also having good sealing, dustproof and waterproof performance.

[0054] like Figure 2 As shown, the angle between the installation direction of the second mounting base 2 and the extension direction of the protective tube assembly 3 is ≤30° (specifically, angle C in the figure is ≤30°).

[0055] The combination of installing the first mounting bracket 1 and the second mounting bracket 2 can increase the gap between the rubber sleeve and the edge of the taillight during the tailgate closing process, preventing wire entrapment.

[0056] like Figure 3 As shown, a second snap-fit ​​cavity 21 is formed on the second mounting base 2, and the second snap-fit ​​cavity 21 is used to snap-fit ​​with the car door.

[0057] This embodiment uses a snap-fit ​​connection structure to enable the second mounting bracket 2 to be quickly installed on the car door.

[0058] In this embodiment, when installing the second mounting seat 2, simply insert the lower part of the second mounting seat 2 into the sheet metal hole of the vehicle body, press the upper part of the second mounting seat 2 until the sheet metal edge is engaged with the second snap-fit ​​cavity 21, and the interference fit of the upper and lower lips can achieve a firm lock and effectively prevent detachment, while also having good sealing, dustproof and waterproof performance.

[0059] In this embodiment, as Figure 1 and Figure 3 As shown, a mounting tail 22 is also formed on the second mounting base 2. (As indicated...) Figure 5As shown, during installation, the wire end of the automotive wiring harness, starting from the side of the vehicle body, is passed sequentially through: the cavity of the first mounting base 1; the entire internal channel of the protective tube assembly 3 connected to the first mounting base 1; and the cavity of the second mounting base 2. Finally, the wire end is pulled out from the mounting tail 22 of the second mounting base 2. The wire harness outside the mounting tail 22 is tightly wrapped and secured to the tail structure using tape. After confirming the wire is securely fixed, the first mounting base 1 and the second mounting base 2 are respectively snapped into the corresponding sheet metal holes on the vehicle body and door according to their preset installation directions.

[0060] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
