[0033] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0034] As attached Figure 1 To Attachment Figure 3As shown, the automobile wiring harness installation structure proposed by the utility model includes a main body 10, which is installed on a body sheet metal 20. A through hole for installing the main body 10 is opened on the body sheet metal 20. The through hole passes through the body sheet metal 20 and connects the first side 201 and the second side 202 of the body sheet metal 20. The main body 10 includes a wiring harness hole 101, which is used to pass the wiring harness 30.

[0035] Combined with Figure 1 and attached Figure 2 A sealing portion 11 and a guide portion are provided on the main body 10. The sealing portion 11 is used to connect with the through hole to make the wiring harness 30 and the through hole sealed. The guide portion is located on at least one of the first side 201 and the second side 202 of the main body 10. The position of the guide portion matches the wiring harness hole 101. The guide portion is configured so that when the wiring harness 30 is inserted into the wiring harness hole 101, the guide portion can contact the wiring harness 30.

[0036] The sealing portion 11 can ensure the sealing of the connection between the main body 10 and the vehicle body sheet metal 20, and has good waterproof and dustproof effects. The guide portion is used to contact the wire harness 30, and can support and guide the wire harness 30 to increase the contact area between the main body 10 and the wire harness 30, which can improve the stability of the wire harness 30, reduce shaking, avoid abnormal noise, and improve the NVH performance of the vehicle.

[0037] In one example, the main body 10 is an EPDM (Ethylene Propylene Diene Monomer) member.

[0038] In one example, the vehicle body sheet metal 20 is a front panel of a vehicle.

[0039] For a car, it has a wet area that is exposed to the external environment and often comes into contact with rain, snow and other water in the external environment, and a dry area that is basically unaffected by the external environment. In one example, the first side 201 mentioned above is the wet area side of the car, and the second side 202 is the dry area side of the car.

[0040] In one embodiment of the present invention, Figure 1 and attached Figure 2 A mounting hole 102 is provided on the main body 10, and the mounting hole 102 is set as a through hole. A positioning piece 21 is convexly provided on the body sheet metal 20, and the positioning piece 21 is matched and connected with the mounting hole 102. When the main body 10 is installed on the body sheet metal 20 through the sealing part 11, the positioning piece 21 is passed through the mounting hole 102, and the positioning piece 21 is fixedly connected with the main body 10 through a fixing piece to fix the main body 10 to the body sheet metal 20. Through the cooperation of the positioning piece 21 and the sealing part 11, the main body 10 can be stably and securely installed on the body sheet metal 20 to prevent the sealing part 11 from failing and falling off after a long period of use, thereby extending the service life.

[0041] In one example, a bushing is inserted into the mounting hole 102 , and the positioning member 21 is inserted into the bushing. The provision of the bushing can improve the structural strength of the main body 10 to ensure reliable connection with the positioning member 21 .

[0042] Optionally, the bushing is made of PP (polypropylene).

[0043] Optionally, the bushing and the main body 10 are connected as one body through an injection molding process.

[0044] In one example, the positioning member 21 is protruded on the second side 202 of the vehicle body sheet metal 20 . Such a configuration can hide the installation traces and improve the overall aesthetics.

[0045] In one example, the positioning member 21 is configured as a projection welding stud, which is connected to the vehicle body sheet metal 20 by welding, and the fixing member is a nut that matches the projection welding stud, which is convenient for disassembly and assembly.

[0046] In one example, the positioning member 21 is interference fit with the mounting hole 102 .

[0047] In one example, the number of the mounting holes 102 is set to four, and the number of the positioning members 21 is set to four, so that the stability of the installation can be improved.

[0048] In one embodiment of the present invention, Figure 1 , Attachment Figure 3 and attached Figure 4 The sealing portion 11 includes a connecting piece 111, which is protruding from one end of the main body 10 close to the first side 201, and the connecting piece 111 is matched with the through hole of the body sheet metal 20. When the sealing portion 11 is connected to the through hole, the connecting piece 111 contacts the hole wall of the through hole and has an interference fit with the through hole. In this way, the main body 10 and the body sheet metal 20 can be sealed by clamping the connecting piece 111 in the through hole. The structure is simple and the installation is convenient.

[0049] In one example, the connecting member 111 and the main body 10 are integrally formed.

[0050] In one example, the connecting member 111 is configured as a circular ring, and the orthographic projection of the connecting member 111 along the axial direction is in a circular ring shape.

[0051] In one example, as shown in the attached Figure 4As shown, the connector 111 includes at least two arc segments, and a weakening area 112 is provided between two adjacent arc segments 111. The provision of the weakening area 112 makes it easy for the arc segment to deform. Since the connector 111 and the through hole have an interference fit, when the connector 111 is clamped in the through hole, the weakening area 112 can make the arc segment easily offset in the radial direction, thereby reducing the difficulty of installation. The provision of the weakening area 112 facilitates molding and demolding, and reduces the overall weight.

[0052] Optionally, at least two arc segments are located on the same circle, that is, at least two arc segments are divided by a circular ring.

[0053] In one embodiment of the present invention, the sealing portion 11 also includes at least one supporting member 113, which is protruding from one end of the main body 10 close to the first side 201, the axial height of the supporting member 113 is less than the axial height of the connecting member 111, and the supporting member 113 is located on the radially outer side of the connecting member 111. When the sealing portion 11 is connected to the through hole, the connecting member 111 is stuck in the through hole, the supporting member 113 is in contact with the second side 202 of the body sheet metal 20, and the supporting member 113 is located on the radially outer side of the through hole.

[0054] The supporting member 113 and the connecting member 111 are radially spaced apart so that the supporting member 113, the connecting member 111 and the body sheet metal 20 cooperate to form a water-containing area. When external water flows to the through-hole, the interference fit between the connecting member 111 and the through-hole prevents external water from entering the through-hole. Even if the connecting member 111 fails due to long-term use, external water enters the through-hole through the gap between the connecting member 111 and the through-hole and will preferentially enter the water-containing area. The supporting member 113 located on the outside of the connecting member 111 can play a secondary waterproof role to prevent water seepage in the vehicle, thereby ensuring the dryness of the second side 202 of the body sheet metal 20.

[0055] In one example, the supporting member 113 is configured as a circular ring, and the orthographic projection of the supporting member 113 along the axial direction is in the shape of a circular ring. Optionally, the supporting member 113 is located on a concentric circle of the connecting member 111 .

[0056] In one example, the number of supporting members 113 is set to two, and they are radially spaced apart on the outside of the connecting member 111. With this arrangement, the two supporting members 113 cooperate with the body sheet metal 20 to form a water-holding area, which can achieve a multi-level waterproof effect. Through the cooperation of the mounting hole 102, the positioning member 21 and the fixing member, the supporting member 113 can fit tightly with the body sheet metal 20, thereby improving the sealing performance.

[0057] In one embodiment of the present invention, Figure 1 and attached Figure 3The guide portion includes a first guide member 12, which is located at one end of the main body 10 close to the first side 201, and / or, is located at one end of the main body 10 close to the second side 202, and the first guide member 12 is protruded from the main body 10, the position of the first guide member 12 is matched with the wiring harness hole 101, and the wiring harness hole 101 passes through the main body 10 and the first guide member 12, when the wiring harness 30 is inserted into the wiring harness hole 101, the first guide member 12 is sleeved on the outside of the wiring harness 30.

[0058] In one example, as shown in the attached Figure 1 As shown, the first guide member 12 is arranged in a columnar shape. Optionally, the first guide member 12 is a cylindrical member or a truncated cone member.

[0059] In one example, the first guide member 12 is integrally formed with the main body 10 .

[0060] In one example, as shown in the attached Figure 3 As shown, the radial dimension of the wiring harness hole 101 gradually decreases from one end of the main body 10 to one end of the second guide member 12. Such a configuration enables the second guide member 12 to have at least one snap-in section that is interference-fitted with the wiring harness 30, so as to improve the connection stability of the wiring harness 30 and prevent external water from entering the second side 202 of the vehicle body sheet metal 20 through the gap between the wiring harness hole 101 and the wiring harness 30.

[0061] In one embodiment of the present invention, as shown in the attached Figure 2 As shown, the guide portion includes a second guide member 13, and the second guide member 13 is protruded at one end of the main body 10 close to the second side 202. Figure 5 As shown, the second guide member 13 includes a support plate 131 and side plates 132 located at both ends of the support plate 131. One end of the support plate 131 is connected to the main body 10, and the other end is a free end. The position of the support plate 131 matches the wiring harness hole 101. When the wiring harness 30 is inserted into the wiring harness hole 101, the support plate 131 contacts the wiring harness 30.

[0062] Refer to the attached Figure 2 The side plate 132 protrudes and extends toward one end away from the body sheet metal 20. When the wire harness 30 is inserted into the wire harness hole 101, the side plate 132 contacts both sides of the wire harness 30. The side plate 132 cooperates with the support plate 131 to support the bottom of the wire harness 30 and limit the side thereof, so as to increase the contact area between the main body 10 and the wire harness 30. After the wire harness 30 passes through the wire harness hole 101, it is guided and limited by the second guide member 13 to prevent the wire harness 30 from shaking during the driving of the vehicle and causing contact friction between the wire harness 30 and the body sheet metal 20, thereby reducing the probability of abnormal noise.

[0063] In one example, the support plate 131 includes a curved surface, and the curved surface is used to cooperate with the outer circumference of the wire harness 30 so that the support plate 131 fits the wire harness 30 .

[0064] In one example, the support plate 131 and the side plate 132 are integrally formed.

[0065] In one example, the second guide member 13 is integrally formed with the main body 10 .

[0066] In one example, as shown in the attached Figure 4 As shown, the support plate 131 and the main body 10 are connected by a reinforcing plate 133, and the reinforcing plate 133 is located on the side of the support plate 131 away from the side plate 132, that is, the reinforcing plate 133 is arranged on the side of the support plate 131 close to the body sheet metal 20. Through the arrangement of the reinforcing plate 133, the connection strength between the support plate 131 and the main body 10 can be increased, and the structural strength of the support plate 131 can be improved, so that the support plate 131 has sufficient supporting force for the wiring harness 30, and the structure is simple and stable.

[0067] Optionally, the reinforcing plate 133 is integrally formed with the supporting plate 131 and the main body 10 .

[0068] In one embodiment of the present invention, as shown in the attached Figure 5 As shown, a notch 134 is formed at one end of the side plate 132 away from the body sheet metal 20. Figure 4 A guide rib 135 is protruded from one end of the support plate 131 away from the side plate 132. The number of the guide ribs 135 is set to two, and they are distributed on the support plate 131 along the axial interval of the wiring harness 30. The interval between the guide ribs 135 is set corresponding to the notch 134, and the notch 134 is connected to the interval. The notch 134 cooperates with the guide rib 135 to set a binding member 136. The binding member 136 passes through the interval between the guide ribs 135 and the notch 134, and is used to fix the wiring harness 30 to the second guide member 13 to prevent the wiring harness 30 from shaking relative to the second guide member 13.

[0069] In one example, the tie 136 is configured as a cable tie.

[0070] In one example, one end of the side panel 132 close to the body sheet metal 20 protrudes from the support plate 131, so that the axial projection of the entire second guide member 13 is "H"-shaped, and the two ends of the guide rib 135 are respectively connected to the two side panels 132. The guide rib 135 can increase the structural strength and stability of the side panel 132.

[0071] In one embodiment of the present invention, Figure 1 and attached Figure 5 The main body 10 is provided with a connecting column 14 at one end close to the first side 201. Figure 6 As shown, the main body 10 is provided with a positioning hole 141 at one end close to the second side 202. The positioning hole 141 passes through the main body 10 and partially passes through the connecting column 14. Figure 7When at least two main bodies 10 are stacked axially, the connecting column 14 of the lower main body 10 is at least partially accommodated in the positioning hole 141 of the upper main body 10. This arrangement facilitates overall storage and transportation.

[0072] In one example, the connecting post 14 is integrally formed with the main body 10 .

[0073] In one example, one end of the connecting column 14 away from the main body 10 includes a small diameter section, which cooperates with the positioning hole 141 . When at least two main bodies 10 are stacked axially, the small diameter section is completely accommodated in the positioning hole 141 .

[0074] In one embodiment of the present invention, as shown in the attached Figure 1 As shown, a blocking member 22 is convexly provided on the end surface of the first side 201 of the body sheet metal 20, and the blocking member 22 encloses a mounting area 23. A through hole is opened in the mounting area 23. When the main body 10 is installed on the body sheet metal 20, the blocking member 22 surrounds the outer periphery of the main body 10. The blocking member 22 can prevent external water from entering the mounting area 23, so as to cooperate with the sealing part 11 to play a waterproof role.

[0075] The automobile wiring harness installation structure of the utility model is adopted. By setting a sealing part 11 on the main body 10, the sealing part 11 can seal and assemble the wiring harness 30 with the through hole on the body sheet metal 20, so as to prevent external water from entering the interior of the vehicle body through the gap between the wiring harness 30 and the through hole, thereby improving the sealing performance of the vehicle, reducing the probability of water seepage and damage to the internal parts of the vehicle body, and having a good dustproof effect. It can also prevent the wiring harness 30 from shaking in the through hole and generating abnormal noise, thereby improving the NVH performance of the vehicle and improving the stability of the installation of the wiring harness 30.

[0076] By arranging a guide portion on the main body 10, the guide portion is used to contact the wire harness 30 installed in the wire harness hole 101 of the main body 10, and the guide portion can guide the wire harness 30 and can increase the contact area between the main body 10 and the wire harness 30. The guide portion cooperates with the sealing portion 11 to reduce the probability of oscillation of the wire harness 30 during vehicle driving, increase the stability and reliability of the installation of the wire harness 30, and has good practicality.
