Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harness installation, in particular to an automotive wire harness protection component. Background Art

[0002] The low-voltage wire harness of an automobile connects various electrical components on the whole vehicle, playing the roles of power distribution and signal transmission, and is an important part of the automobile. During the design of the wire harness system, it is necessary to combine the working environments of various regions of the whole vehicle to ensure the stability of the wire harness system. Waterproof performance is an important index in wire harness design. When conducting waterproof design, the wading depth of the whole vehicle needs to be considered. The maximum wading depth of an automobile refers to the height of the wading line from the ground. The wading line usually refers to the horizontal plane of the deepest water area that the automobile can pass through when driving at a speed of 10 km / h. When designing the automobile, it is necessary to make the positions of key electronic components above the wading line.

[0003] The position below the wading line is usually called the wet area, and the parts outside the wet area in the automobile are the dry area. During wire harness assembly, the assembly is usually carried out by the method of press-fitting through holes from the wet area to the dry area of the vehicle. This assembly method requires a certain assembly space to be reserved in the wet area. Otherwise, it will lead to difficult assembly. However, there will also be a visual blind area on the premise of reserving the assembly space. Therefore, when pulling the wire harness in the dry area of the vehicle for assembly, problems such as incomplete assembly or excessive pulling may occur due to the operation in the visual blind area, affecting the accuracy and efficiency of the assembly.

[0033] The wire harness rubber part has been widely used as a necessary component in the field of automotive wire harnesses. During assembly, generally, the method of press-fitting through holes from the wet area to the dry area of the vehicle is adopted for assembly. This assembly method requires a certain amount of hand-operating space to be reserved on the wet area side. When the assembly space on the wet area side cannot be satisfied, it will directly lead to assembly difficulties. Therefore, when considering adopting the method of pulling the wire harness in the dry area of the vehicle for assembly, it is necessary to prevent the situation of incomplete assembly or excessive pulling caused by blind operation. To solve the problem of pulling and assembling the wire harness rubber part in a space-compact area and improve the assembly efficiency at the same time, the present utility model provides an automotive wire harness protection assembly. Figure 1 The structural schematic diagram of the automotive wire harness protection assembly provided by an embodiment of the present utility model; Figure 2 The side view of the automotive wire harness protection assembly provided by an embodiment of the present utility model; Figure 3 The axial structural schematic diagram of the automotive wire harness protection assembly provided by an embodiment of the present utility model. Combining Figures 1 to 3 As shown, an automotive wire harness protection assembly provided by an embodiment of the present utility model includes:

[0034] An elastic protective sleeve 100, made of an elastic material, for protecting the automotive wire harness. A first through hole 101 for passing through the automotive wire harness is provided on the elastic protective sleeve 100, and a first guiding structure is provided on the elastic protective sleeve 100;

[0035] The guiding skeleton 200 is sleeved outside the elastic protective sleeve 100 and is used to support the elastic protective sleeve 100. A second through hole 201 for threading the vehicle wiring harness is provided on the guiding skeleton 200. A second guiding structure is provided on the guiding skeleton 200, and the second guiding structure is used to cooperate with the first guiding structure to limit the relative positions of the elastic protective sleeve 100 and the guiding skeleton 200 when installing the protection assembly.

[0036] Among them, the vehicle wiring harness refers to a system on the vehicle composed of multiple cables and connectors for transmitting electricity and signals. The cable is composed of copper wires and aluminum wires for transmitting electrical energy and signals and an insulating material coated on the outside. According to the different connected areas, the vehicle wiring harness can be divided into engine wiring harness, body wiring harness, instrument panel wiring harness, door wiring harness, etc. As Figure 1 shown, the guiding skeleton 200 is sleeved outside the elastic protective sleeve 100. To facilitate the threading of the wiring harness, the first through hole 101 and the second through hole 201 are coaxially installed. The axial dimension of the elastic protective sleeve 100 is greater than the axial dimension of the guiding skeleton 200, so as to be able to protect the extended wiring harness and prevent the wiring harness from being bent at the edge of the protection assembly when stressed. The elastic protective sleeve 100 is made of an elastic material and can allow a certain degree of deformation, and can play a buffering and protecting role when subjected to external forces. The elastic material needs to have properties such as wear resistance, heat resistance, chemical corrosion resistance and weather resistance, and can include ethylene propylene rubber, neoprene, silicone rubber or thermoplastic elastomer, etc. The guiding skeleton 200 sleeved outside the elastic protective sleeve 100 can play a protective role and is also convenient for holding and installing. The preparation material of the guiding skeleton 200 needs to have certain wear resistance, heat resistance and mechanical strength, and can be made of engineering plastics and other materials. The first guiding structure and the second guiding structure can have various implementation manners. For example, the first guiding structure can be a guiding block or a guiding groove, and the second guiding structure can be a guiding groove or a guiding block that cooperates with it, or a snap structure, a connecting piece and other structures are used to limit the relative positions of the elastic protective sleeve 100 and the guiding skeleton 200. The elastic protective sleeve 100 and the guiding skeleton 200 can be in a cylindrical shape or a stepped shape, and the inner surface shapes can be the same or cooperate with each other to improve the tightness and stability of the cooperation. The outer contour shape can be a circle as shown in the figure, or other shapes. Chamfer or fillet structures are provided at the transitions of the elastic protective sleeve 100 and the guiding skeleton 200 to avoid stress concentration and improve the safety of the installation process.

[0037] The above-mentioned automotive wire harness protection component includes an elastic protective sleeve 100 made of an elastic material, which can absorb and mitigate external vibrations and impacts, protecting the automotive wire harness from mechanical damage. A first through-hole 101 for threading the automotive wire harness is provided on the elastic protective sleeve 100, which can limit the position of the wire harness, prevent movement or detachment, and enhance the protection effect. A first guiding structure is provided on the elastic protective sleeve 100; a guiding skeleton 200, the guiding skeleton 200 is sleeved outside the elastic protective sleeve 100 and is used to support the elastic protective sleeve 100, which can enhance the protection ability of the protection component for the automotive wire harness. A second through-hole 201 for threading the automotive wire harness is provided on the guiding skeleton 200. A second guiding structure is provided on the guiding skeleton 200, and the second guiding structure is used to cooperate with the first guiding structure to limit the relative position of the elastic protective sleeve 100 and the guiding skeleton 200 when installing the protection component. The cooperation of the first guiding structure and the second guiding structure can limit and reduce the probability of installation errors, simplify the installation process, and improve the installation efficiency and reliability.

[0038] As Figures 1 to 3 shown, in one embodiment, the first guiding structure includes a flange 102 provided at the first end of the elastic protective sleeve 100. The flange 102 is provided with a first groove 103 along the circumferential direction. The second guiding structure includes a first flange 202 provided along the circumferential direction at the first end of the guiding skeleton 200. The first flange 202 is used to be installed in the first groove 103 to limit the axial relative movement between the elastic protective sleeve 100 and the guiding skeleton 200. Among them, the flange 102 refers to a vertical edge or curled edge formed at the edge of the elastic protective sleeve 100. The flange 102 can make the edge of the elastic protective sleeve 100 more solid and can also provide a reliable connection surface between the elastic protective sleeve 100 and the guiding skeleton 200. The flange 102 can be made by processes such as injection molding, thermoforming, or machining. The first groove 103 refers to a groove formed between the flange 102 and the outer surface of the elastic protective sleeve 100. The first flange 202 refers to an annular part formed at the edge of the guiding skeleton 200. When the elastic protective sleeve 100 and the guiding skeleton 200 are installed in place, the first flange 202 can be accommodated in the first groove 103 to prevent the axial relative movement between the elastic protective sleeve 100 and the guiding skeleton 200, thereby ensuring the accuracy and stability of the installation. The sizes of the first groove 103 and the first flange 202 can be set according to the size of the wire harness protection component, and the present application does not limit this.

[0039] Figure 4 is a schematic structural diagram of the elastic protective sleeve 100 of the automotive wire harness protection component provided by an embodiment of the present utility model; Figure 5 is a schematic structural diagram of the guiding skeleton 200 of the automotive wire harness protection component provided by an embodiment of the present utility model. As Figures 4 to 5As shown, in one embodiment, a protruding rib 104 is provided in the first groove 103, and a second groove 203 is provided on the first flange 202. The protruding rib 104 is used to cooperate with the second groove 203 to limit the relative rotation of the elastic protective sleeve 100 and the guiding skeleton 200. Herein, the protruding rib 104 refers to a raised portion formed on the surface of the first groove 103. A plurality of protruding ribs 104 can be provided along the circumferential direction in the first groove 103, and the positions of the protruding ribs 104 can be symmetric. Correspondingly, there can also be a plurality of second grooves 203, which are arranged along the circumferential direction of the first flange 202. The interval between two adjacent second grooves 203 should be consistent with the interval between two adjacent protruding ribs 104. The size of the second groove 203 should be at least capable of accommodating the protruding rib 104. When the protruding rib 104 and the second groove 203 are installed in place, the relative rotation of the elastic protective sleeve 100 and the guiding skeleton 200 can be limited. Through the mutual cooperation of the first groove 103, the protruding rib 104, the first flange 202, and the second groove 203, the relative positions of the elastic protective sleeve 100 and the guiding skeleton 200 can be limited, preventing phenomena such as misalignment or detachment during the installation process, and facilitating the smooth installation of the wire harness protection assembly in the blind area of vision.

[0040] As Figure 5 shown, in one embodiment, the guiding skeleton 200 is provided with a plurality of claw teeth 204 along the circumferential direction. The claw teeth 204 are used to engage with the mounting holes of the vehicle to fix the wire harness protection assembly. The claw teeth 204 are arranged along the circumferential direction on the side wall of the guiding skeleton 200, with one end connected to the guiding skeleton 200 and the other end suspended, so as to achieve a certain degree of elastic deformation, facilitating installation and fixation.

[0041] Figure 6 This is a schematic structural diagram of the guiding skeleton 200 of the wire harness protection assembly for a vehicle provided by an embodiment of the present utility model. In one embodiment, a stop portion 205 is provided on the claw teeth 204. The stop portion 205 protrudes from the surface of the claw teeth 204 and is used to limit the axial displacement of the wire harness protection assembly after the wire harness protection assembly is installed in place. After the wire harness protection assembly is installed in place, the stop portion 205 can abut against the opening through which the vehicle wire harness passes to play a limiting role. The claw teeth 204 can also produce a sound when installed in place, providing a sound prompt for the operator.

[0042] In one embodiment, the claw teeth 204 and the second grooves 203 are arranged alternately. As Figure 5 shown, arranging the claw teeth 204 and the second grooves 203 alternately along the circumferential direction of the guiding skeleton 200 can take into account both the strength of the guiding skeleton 200 and the installation accuracy.

[0043] In one embodiment, the size of the elastic protective sleeve 100 gradually decreases from the first end to the second end. The size of the first end of the elastic protective sleeve 100 is larger, which is convenient for passing through the wire harness and cooperating with the guiding skeleton 200. The size of the second end for leading out the wire harness is smaller, which is convenient for gathering the wire harness and saving the installation space. The structure of the elastic protective sleeve 100 can be a multi-segment structure as shown in Figures 1 to 4 The first segment is a hollow conical cylindrical structure, with a flanging 102 formed at the larger-sized end and the smaller-sized end connected to the second segment. The second segment is a cylindrical structure. In other embodiments, the elastic protective sleeve 100 can also be a single-segment or more than two-segment structure, which can be set according to factors such as the actual type of wire harness and installation area.

[0044] In one embodiment, the edges of the elastic protective sleeve 100 and the guiding skeleton 200 are rounded structures. The edges of both the elastic protective sleeve 100 and the guiding skeleton 200 are provided with chamfered structures, which can better adapt to the assembly method of pulling the wire harness during installation inside the vehicle and blind operation, effectively saving the space resources on the wet area side.

[0045] In one embodiment, the preparation material of the elastic protective sleeve 100 includes ethylene propylene diene monomer (EPDM). This material has excellent anti-aging and weather resistance properties and can provide excellent sealing and weather resistance for automotive wire harnesses. In some embodiments, the preparation material of the elastic protective sleeve 100 can also include one or more of neoprene, silicone rubber, polyurethane rubber, and thermoplastic elastomer.

[0046] In one embodiment, the preparation material of the guiding skeleton 200 includes thermoplastic engineering plastic (PA6-GF15, polyamide 6 reinforced material). This material has good heat resistance, and the glass fiber contained therein gives the material high tensile strength and rigidity. Using the material prepared with PA6-GF15 can combine strength and rigidity, making the wire harness protection assembly more durable and reliable. In some embodiments, the preparation material of the guiding skeleton 200 can also include composite materials such as nylon 66-glass fiber reinforced, polypropylene-glass fiber reinforced, and polycarbonate-glass fiber reinforced.

[0047] In one embodiment, both the elastic protective sleeve 100 and the guiding skeleton 200 can be made by die molding process.

[0048] Compared with the existing assembly method of wire harness rubber parts, the top of the guiding skeleton 200 of the wire harness protection component provided by the present utility model has a chamfer design, which can adapt to the assembly method under the condition of pulling the wire harness inside the vehicle and blind operation, effectively saving the space resources on the wet area side. One end of the elastic protective sleeve 100 is provided with a flanging, and protruding ribs are added inside the flanging. The guiding skeleton 200 is matched with the four protruding ribs of the elastic protective sleeve 100 through four grooves to limit the relative rotation between the guiding skeleton 200 and the elastic protective sleeve 100. Four claw catches are arranged on the periphery of the guiding skeleton 200 to ensure that the whole wire harness rubber part can be installed in place during the blind installation process, improving the assembly rhythm and having a clear sound prompt, and can adapt to the assembly method of pulling the wire harness inside the vehicle. On the basis of ensuring the original functions of the wire harness rubber part, a plastic guiding skeleton 200 with claw catches 204 and guiding ability is wrapped on the rubber part to realize blind operation. By using the limiting and guiding ability of the guiding skeleton 200, the assembly difficulty is reduced, the assembly quality is ensured, the assembly speed is increased, and the space resources on the wet area side can be effectively saved.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0050] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
