For example, the displays are installed on the B-pillars that support the roof and connect the front and rear doors, showing the vehicle's current status information as well as external information such as weather forecasts and news summaries.

[0003] When electronic components such as vehicle displays are located in the pillar area, the internal environment of the pillar is easily affected by external climate conditions. For example, in the case of high temperature and high humidity or drastic temperature changes, water vapor in the air can easily condense on the surface of the wiring harness, which is at a lower temperature. This condensation can easily seep into the vehicle through the wiring harness through-holes on the outer panel of the pillar, leading to the risk of electrical faults such as short circuits and leakage in the relevant electronic components inside the pillar. Utility Model Content

The width of the sealing groove is less than the thickness of the wire harness seal, so that the wire harness seal forms a first engaging part and a second engaging part on opposite sides of the sealing groove. During installation, the first engaging part and the second engaging part abut against the inner and outer sides of the outer plate of the column, respectively.

[0008] Optionally, the outlet is eccentrically positioned above the wire harness seal to increase the distance between the outlet and the lowest point of the guide section.

[0009] Optionally, the second snap-fit ​​portion is provided with a sealing lip that extends into the sealing groove, the sealing lip being used to abut against the outer plate of the column.

[0032] Please see Figure 1 and Figure 2The present invention also proposes an automobile, including a pillar 3. Specifically, the pillar 3 of the present invention includes a pillar outer plate 31 and a pillar trim 32. The pillar outer plate 31 and the pillar trim 32 extend approximately along the height direction of the automobile. The pillar trim 32 is fixed to the side of the pillar outer plate 31 away from the passenger compartment by means of fastener connection, snap-fit, etc. The pillar trim panel 32 is equipped with electronic components 5 such as a screen entertainment host 51 and an NFC controller 52. In this embodiment, the pillar trim panel 32 is also equipped with a wiring harness assembly. Specifically, the wiring harness assembly includes a wiring harness body 1 and a wiring harness seal 2. The pillar outer plate 31 has a wiring harness through hole, and the wiring harness seal 2 passes through the wiring harness through hole and is fixedly connected to the pillar outer plate 31 by at least one of snap-fit ​​and interference fit. The wiring harness seal 2 is integrally injection molded from materials such as rubber and silicone, and has wear-resistant and flexible properties, which facilitates installation and improves the sealing between the wiring harness body 1 and the pillar outer plate 31, preventing condensation and moisture on the surface of the wiring harness body 1 from seeping into the vehicle interior through the wiring harness through hole, thereby improving the vehicle's environmental adaptability and safety. It should be noted that this utility model does not limit the type of electronic component 5 or the installation position of the wiring harness assembly.

[0033] Please see Figures 3 to 5 Furthermore, the wiring harness body 1 passes through the wiring harness seal 2 fixed to the outer plate 31 of the pillar, and extends to form a first wiring harness 11 and a second wiring harness 12 on the outer and inner sides of the outer plate 31, respectively. The ends of both the first wiring harness 11 and the second wiring harness 12 are provided with connectors 13, which are used to establish electrical signal connections with electronic components 5 installed on the inner and outer sides of the outer plate 31, respectively. Specifically, the first wiring harness 11 is located on the outer side of the outer plate 31, and includes an upper wiring harness 112 and a lower wiring harness 113. The upper wiring harness 112 and the lower wiring harness 113 are respectively connected to the interfaces of the screen entertainment host 51 and the NFC controller 52 via corresponding connectors 13. Furthermore, the second wiring harness 12 is located on the inner side of the outer plate 31, and is connected to the interfaces of the entertainment host and power module inside the vehicle via connectors 13 at its ends.

[0034] Please see Figure 6 In one embodiment, the screen entertainment host 51 is located on the upper part of the pillar trim panel 32, the NFC controller 52 is located on the lower part of the pillar trim panel 32, the wiring harness through hole is located below the NFC controller 52, and the portion of the first wiring harness 11 near the interface between the screen entertainment host 51 and the NFC controller 52 extends along the vertical direction of the vehicle to prevent condensation on the surface of the wiring harness body 1 from flowing to the interface of the aforementioned electronic component 5.

[0035] In one embodiment, the portion of the first wiring harness 11 near the wiring harness through-hole is bent downward relative to the other portion to form a guide section 111. Condensation on the wiring harness body 1 flows downward due to gravity, and the guide section 111 guides the condensation on the surface of the first wiring harness 11 to the lowest point of the guide section 111, preventing condensation from flowing into the inner side of the pillar outer panel 31 along the inlet 24 of the wiring harness seal 2, thereby improving waterproofing performance. During installation, the upper wiring harness 112 extends from the end of the guide section 111 along the front-rear direction of the vehicle, extends to the area near the edge of the pillar trim panel 32, and then runs upward, connecting to the screen entertainment host 51 via connector 13. The lower wiring harness 113 extends from the end of the guide section 111 along the front-rear direction of the vehicle and then runs upward, connecting to the interface of the NFC controller 52 via connector 13. Since the space between the column trim panel 32 and the column outer panel 31 is small, the first wiring harness 11 is arranged in the above manner to achieve waterproofing while avoiding interference between the first wiring harness 11 and surrounding components, and to save space and improve space utilization.

[0036] Please see Figure 7 In some embodiments, a wire harness fixing member is provided on the column trim panel 32 or the column outer panel 31 to fix the first wire harness 11 to the column trim panel 32 and guide the direction of the first wire harness 11. The wire harness fixing member can be a buckle 321 or a strap, etc. As shown in the figure, in one embodiment, the wire harness fixing member is a buckle 321, which is fixed to the column trim panel 32 by adhesive bonding, snap-fitting, etc., or the buckle 321 is integrally formed with the column trim panel 32. Optionally, the buckle 321 is "L" shaped, "U" shaped, etc. Specifically, the buckle 321 includes a fixing plate 322 and a side plate 323. The column trim panel 32 protrudes from its surface toward the column outer panel 31 to form the side plate 323, and the side plate 323 bends and extends from its end away from the column trim panel 32 to form the fixing plate 322. During installation, the wire harness body 1 is inserted into the wire harness fixing component and clamped between the fixing plate 322 and the column decorative panel 32, thereby fixing the first wire harness 11 to the column decorative panel 32, and the installation is convenient.

[0037] The column 3 includes a sealing component 4, which includes a first sealing strip 41 and a second sealing strip 42. Optionally, the first sealing strip 41 is fixed to the area near the edge of the column trim 32 by means of waterproof adhesive bonding, snap-fit, or fastener connection, and is sandwiched between the column trim 32 and the column outer plate 31, serving as a seal and waterproofing function, and also facilitating installation. The second sealing strip 42 surrounds the aforementioned electronic components 5. Specifically, the second sealing strip 42 includes an upper sealing strip 421 and a lower sealing strip 422 respectively surrounding the screen entertainment host 51 and the NFC controller 52. The sealing strips are made of materials such as foam, rubber, silicone, and polyurethane. In this embodiment, the housing of the electronic components 5, such as the screen entertainment host 51 and the NFC controller 52, is provided with a cover plate 53. The second sealing strip 42 is sandwiched between the cover plate 53 and the column trim 32 and is fixedly connected to the cover plate 53 by means of sealant bonding. The cover plate 53 is made of plastic material, reducing costs. The sealing assembly 4 is provided with a mounting hole for the first wire harness 11 to pass through. The first wire harness 11 passes through the mounting hole and is fixedly connected to the corresponding sealing strip by sealant, thereby further achieving a sealing and waterproof effect.

[0038] Optionally, a waterproof ring 14 is provided on the first wire harness 11. The waterproof ring 14 is made of elastic materials such as silicone or rubber. Specifically, the waterproof ring 14 is fitted onto the area of ​​the first wire harness 11 near its end connector 13 and is fixedly connected to the second sealing strip 42 by means of waterproof adhesive, so that the first wire harness 11 fits better with the surrounding components and improves the sealing performance. The sealing component 4, the waterproof ring 14, and the cover plate 53 are fixedly connected to each other by means of waterproof adhesive, which can ensure the sealing performance at the interface of the electronic component 5. In this embodiment, the connector 13 can be a non-waterproof connector 13, which can effectively reduce costs compared with the waterproof connector 13 in the prior art.

[0039] In some embodiments, the wire harness seal 2 has a wire inlet 24 and a wire outlet 25 connected on opposite sides for the wire harness to pass through. The outer surface of the wire harness seal 2 is recessed inward to form a sealing groove 21 for engaging with the column outer plate 31. The width of the sealing groove 21 is less than the thickness of the wire harness seal 2, so that the wire harness seal 2 forms a first engaging part 22 and a second engaging part 23 on opposite sides of the sealing groove 21. During installation, the first engaging part 22 is used to pass through the wire harness through hole of the column outer plate 31 and abut against the side of the column outer plate 31 near the carriage, and the second engaging part 23 is used to abut against the side of the column outer plate 31 away from the carriage.

[0040] Optionally, the outlet 25 is eccentrically positioned on the upper part of the wiring harness seal 2, thereby increasing the distance between the outlet 25 and the lowest point of the guide section 111, and making the guide section 111 more inclined relative to the front and rear directions of the vehicle, which is beneficial for guiding condensate to the lowest point of the guide section 111 and preventing condensate from flowing into the vehicle through the inlet 24 and outlet 25.

[0041] In one embodiment, the second snap-fit ​​portion 23 is provided with a sealing lip 231 extending into the sealing groove 21. Optionally, the second snap-fit ​​portion 23 protrudes from its edge toward the sealing groove 21 to form the sealing lip 231. The sealing lip 231 abuts against the outer plate of the pillar to prevent condensation and other substances from seeping into the vehicle interior through the wiring harness through hole of the outer plate of the pillar 31, thereby improving the sealing performance between the wiring harness seal 2 and the outer plate of the pillar 31.

[0042] Optionally, the width of the sealing groove 21 gradually decreases along the direction close to the wire harness through hole. The width of the sealing groove 21 on the side close to the wire harness through hole is less than the thickness of the corresponding wire harness through hole portion of the column outer plate 31. This allows the first snap-fit ​​portion 22 and the second snap-fit ​​portion 23 to be securely clamped to the inner and outer sides of the column outer plate 31, ensuring the sealing performance between the wire harness seal 2 and the column outer plate 31 while facilitating installation and improving the stability of the installation.

[0043] In one embodiment, the wire harness seal 2 is provided with a guide cylinder 221 in the area corresponding to the outlet 25. Specifically, a portion of the first snap-fit ​​portion 22 protrudes outward to form the guide cylinder 221. The guide cylinder 221 is hollow cylindrical and has an outlet channel communicating with the outlet 25 along its axial direction. The guide cylinder 221 extends downward or extends downward at an angle relative to the outer plate 31 of the column to guide the wire harness body 1 through the portion of the wire harness seal 2. Optionally, the guide cylinder 221 protrudes radially outward from the end away from the first snap-fit ​​portion 22 to form a reinforcing flange 222, thereby improving the structural strength of the guide cylinder 221. Optionally, a waterproof layer is provided between the guide cylinder 221 and the wire harness body 1. Specifically, the waterproof layer is formed by filling the space between the guide cylinder 221 and the wire harness body 1 with a waterproof material such as cement. In this embodiment, the shape of the anti-cement and the guide cylinder 221 are adapted to each other. The gap between the anti-cement filling harness and the guide cylinder 221 is prevented from the infiltration of water vapor into the vehicle, thus improving the sealing performance. In addition, the cost is low.

[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
