Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a long cylindrical rubber part used for automotive wing door wiring harness. Background Technology

[0002] The automotive door wiring harness is a core component connecting electrical systems such as door locks, window and door controllers, and audio systems. Its functional stability directly determines the safe operation and user experience of the door and even the entire vehicle. Since the wiring harness moves with the door during opening and closing, it requires specialized protective components to prevent damage from friction, interference, and environmental corrosion (dust, rain), while also ensuring the installation stability and the reliability of signal and power transmission.

[0003] There are already various door wiring harness protection solutions in the existing technology. For example, Chinese patent CN221497908U discloses a wiring harness pipeline consisting of a body connecting pipe, a flexible movable pipe, and a hinge connecting pipe connected end to end. By limiting the movable part of the wiring harness to a flexible movable pipe, the range of movement of the wiring harness is reduced, thereby avoiding interference between the wiring harness and surrounding parts such as the fender when the door is opened and closed. This patent uses a corrugated pipe structure to improve the waterproof performance of the pipeline, and achieves detachable fixing through body end brackets and hinge end brackets, which improves the wiring harness protection effect and installation convenience of conventional doors to a certain extent.

[0004] However, the aforementioned existing technical solutions are mainly designed for car door types with relatively simple motion trajectories. When applied to car wing doors with more complex motion trajectories, they still have significant drawbacks: First, the opening and closing of wing doors is usually accompanied by a combination of rotation and lifting motion. The required travel and spatial attitude change of the wiring harness are much greater than those of conventional car doors. The L-shaped segmented pipeline structure and the limited length of the flexible moving tube in the patent are difficult to adapt to this complex motion trajectory, which can easily lead to excessive stretching or bending of the protection pipeline during movement, resulting in pipeline rupture or internal wiring harness breakage. Second, the existing solutions lack a dedicated structure to ensure stable connection between the door wiring harness and the floor wiring harness. Moreover, the overall stability of the wiring harness after installation depends on the connection between the bracket and the hinge. Under the complex motion conditions of wing doors, it is easy for it to loosen, which not only reduces the reliability of protection but also requires the entire pipeline to be disassembled during subsequent maintenance, making the operation cumbersome.

[0005] In addition to the patented solutions mentioned above, traditional automotive door wiring harness protection components also suffer from problems such as low installation accuracy and simple fixing structure. For example, traditional protection components do not have a wiring harness docking structure designed, and the connection between the door wiring harness and the floor wiring harness requires the use of external plugs, which not only increases the assembly process, but also easily leads to unstable signal transmission due to docking gaps.

[0006] In summary, existing door wiring harness protection solutions cannot adapt to the special motion characteristics and high protection requirements of automotive wing doors, and have problems such as poor adaptability to complex motion and unstable wiring harness connection. Utility Model Content

[0007] This invention proposes a long cylindrical rubber component for automotive wing door wiring harnesses, which solves the problems of poor adaptability to complex movements and unstable wiring harness connectivity in the prior art.

[0008] The technical solution of this utility model is implemented as follows: A long cylindrical rubber component for automotive wing door wiring harnesses includes a rubber body with a long cylindrical structure. One end of the rubber body is integrally connected to a sealing structure, and the other end is integrally connected to a connector. A skeleton for connection with a mating plug is snapped onto the connector. This long cylindrical, integrally molded structure avoids the defects of traditional segmented structures, such as easy stretching and breakage or tangling, ensuring the rubber component maintains structural stability throughout the door's full operational movement, thereby improving the rubber component's adaptability to complex movements.

[0009] The connector has a slot on its inner side and a retaining plate at the edge of the frame. The slot and retaining plate engage to secure the frame to the connector, ensuring stable installation of the frame on the connector.

[0010] The skeleton is a rectangular ring structure, with the retaining plate arranged perpendicular to the axis of the rectangular ring structure. The rectangular ring structure is adapted to the rectangular interface contour of the connector, and the fit between the retaining plate and the retaining slot restricts the axial movement of the skeleton.

[0011] The frame is provided with a spring clip for engaging with the docking plug. The spring clip extends outward from the frame, and when the long cylindrical rubber component is connected to the docking plug, the spring clip engages with the docking plug.

[0012] The spring clips are symmetrically arranged on a set of opposite sides of the rectangular ring structure. The symmetrical arrangement of the spring clips can provide uniform clamping force when they mate with the docking plug, ensuring the stability of the connection between the frame and the docking plug, avoiding loosening of the connection due to the vibration of the wing door, and thus realizing reliable connection between the wing door wiring harness and the vehicle floor wiring harness, ensuring the continuity of signal transmission and power supply.

[0013] The sealing structure is a flared structure that makes tight contact with the door sheet metal hole. The flared structure precisely matches the contour of the wing door's door sheet metal hole, ensuring tight contact with the hole throughout the entire opening and closing process, thus forming an initial seal.

[0014] The inner side of the flared structure has an annular protrusion that fits snugly against the edge of the door sheet metal hole. The annular protrusion engages with the edge of the door sheet metal hole, ensuring a stable connection between the sealing structure and the door sheet metal.

[0015] An integrally connected retaining ring is provided on the outer surface of the rubber body. The retaining ring is used to fix the long cylindrical rubber component to the car door. Specifically, a cable tie is used to connect the long cylindrical rubber component to the car door by passing through the retaining ring. This restricts the movement of the long cylindrical rubber component and ensures the installation stability of the long cylindrical rubber component.

[0016] The rubber body has a receiving cavity for threading the wire harness, and the inner wall of the receiving cavity is provided with a wear-resistant layer. The wear-resistant layer can significantly reduce the wear rate of the wire harness insulation layer and extend the service life of the wire harness when the frequent movement of the wing door causes relative friction between the wire harness and the inner wall of the receiving cavity.

[0017] The length of the elongated cylindrical structure ranges from 700 to 900 mm. This length range can fully cover the wiring harness movement requirements of the Pengyi door from its closed to its opening limit, avoiding excessive stretching due to insufficient length or entanglement interference caused by redundant length.

[0018] The beneficial effects of this utility model are: 1. The long cylindrical rubber parts have good compatibility with composite materials. The long cylindrical one-piece molding structure, combined with the length design of 700mm~900mm, can fully cover the large stroke requirements of the composite motion of the Pengyi door's rotation and lifting, avoiding the defects of traditional segmented structures that are prone to stretching and breaking or entanglement, and ensuring that the rubber parts always maintain structural stability during the full working condition of the door.

[0019] 2. The long rubber parts have good connection stability after installation. The slots and plates of the connector and the frame cooperate, and the symmetrical spring pieces of the frame and the docking plug cooperate to form a double stable connection structure. This can resist the risk of loosening caused by the vibration of the wing door, ensure reliable connection between the door wiring harness and the floor wiring harness, and avoid signal interruption or unstable power supply.

[0020] In addition, by connecting the long rubber component to the car door through the fixing hole with cable ties, the range of motion of the long rubber component is further restricted, thereby improving the installation stability of the long rubber component.

[0021] 3. The long cylindrical rubber component protects the wire harness. The wear-resistant layer on the inner wall of the cavity is made of highly elastic wear-resistant rubber, which can significantly reduce the friction loss between the wire harness and the cavity wall, while buffering vibration and impact, effectively extending the service life of the wire harness and reducing the cost of later maintenance and replacement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, as Figure 1 , Figure 2 , Figure 3 As shown, a long cylindrical rubber component for automotive wing door wiring harnesses includes a rubber body 1, which is a long cylindrical structure. A sealing structure 11 is integrally connected to one end of the rubber body 1, and a connector 13 is integrally connected to the other end. A skeleton 2 for connection with a mating plug is snapped onto the connector 13. The sealing structure 11 and the connector 13 are simultaneously integrally vulcanized with the rubber body 1, avoiding the defects of traditional segmented structures that are prone to stretching breakage or entanglement. This ensures that the rubber component maintains structural stability throughout the entire operating condition of the door, thereby improving the adaptability of the rubber component to complex movements.

[0027] Furthermore, the inner side of the connector 13 is provided with a slot 131, and the edge of the frame 2 is provided with a retaining plate 21. The slot 131 and the retaining plate 21 engage with each other. This achieves the connection and fixation between the frame 2 and the connector 13, ensuring the frame 2 is stably installed on the connector 13. In addition, the frame 2 has a rectangular ring structure, and the retaining plate 21 is arranged perpendicular to the axis of the rectangular ring structure. The slot 131 is an annular groove, located on the inner side of the connector 13, and the retaining plate 21 is an annular plate, located at the end of the frame 2. The rectangular ring structure is adapted to the rectangular interface contour of the connector, and the engagement of the retaining plate 21 and the slot 131 restricts the axial movement of the frame 2.

[0028] Furthermore, the frame 2 is provided with spring tabs 22 for engaging with the docking plug. The spring tabs 22 extend outwards from the frame 2, engaging with the docking plug when the long cylindrical rubber component is connected. The spring tabs 22 are symmetrically arranged on a set of opposite sides of the rectangular ring structure. In this embodiment, two spring tabs 22 are provided on one side of the rectangular ring structure, and two spring tabs 22 are symmetrically arranged on opposite sides of the rectangular ring structure. The symmetrically arranged spring tabs 22 can provide uniform clamping force when engaging with the docking plug, ensuring the stability of the connection between the frame 2 and the docking plug, preventing loosening due to vibration of the wing door movement, and thus achieving reliable connection between the wing door wiring harness and the vehicle floor wiring harness, ensuring the continuity of signal transmission and power supply.

[0029] Example 2, based on Example 1, provides a long cylindrical rubber component for a wiring harness in an automotive wing door. The sealing structure 11 is a flared structure, which makes tight contact with the door sheet metal hole. The flared structure precisely matches the contour of the wing door's sheet metal hole, ensuring constant tight contact throughout the entire opening and closing process, forming a preliminary seal. An annular protrusion 111 is provided on the inner side of the flared structure, fitting snugly against the edge of the door sheet metal hole. The annular protrusion 111 engages with the edge of the door sheet metal hole, ensuring a stable connection between the sealing structure 11 and the door sheet metal.

[0030] Furthermore, an integrally connected fixing ring 12 is provided on the outer surface of the rubber body 1. The fixing ring 12 is used to fix the long cylindrical rubber part on the car door. Specifically, a cable tie is used to pass through and fix the long cylindrical rubber part to the car door, restricting the movement of the long cylindrical rubber part and ensuring the installation stability of the long cylindrical rubber part.

[0031] Furthermore, the rubber body 1 has a receiving cavity for threading the wire harness, and the inner wall of the receiving cavity is provided with a wear-resistant layer. The wear-resistant layer can significantly reduce the wear rate of the wire harness insulation layer and extend the service life of the wire harness when the frequent movement of the wing door causes relative friction between the wire harness and the inner wall of the receiving cavity.

[0032] Furthermore, the length of the elongated cylindrical structure ranges from 700 to 900 mm. This length range can fully cover the wiring harness movement requirements of the wing door from its closed to its opening limit, avoiding excessive stretching due to insufficient length or entanglement interference caused by redundant length.
