Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and more specifically, to a side sealing structure and a vehicle. Background Technology

[0002] In the A-pillar area of ​​the front fender, side panels, and front doors of a car, there is usually an exterior trim panel. The upper end of this trim panel mates with the side panel, the lower end mates with the front fender, and the sides mate with the front door, side triangular windows, and side trim strips. Because this trim panel needs to mate with many parts, there are many gaps between the parts. Therefore, sealing strips are also installed to solve the wind noise problem caused by the gaps.

[0003] However, the installation of the sealing strip in the A-pillar area often relies on the side trim strip, resulting in poor installation stability. Under the wind pressure and vehicle vibration at high speeds, it will deform or vibrate, affecting the sealing performance and generating new wind noise, thus affecting the overall NVH (Noise, Vibration, and Harshness) performance of the vehicle. Utility Model Content

[0004] In view of this, this application provides a side sealing structure and vehicle to solve the technical problem of poor installation stability of the sealing strip in the A-pillar area.

[0005] One embodiment of this application provides a side panel sealing structure, including an exterior trim panel, a first seal, and a snap-fit ​​member. The first seal is at least partially disposed between a side trim strip and the exterior trim panel of a vehicle. The lower end of the first seal extends to the front fender of the vehicle. The first seal is used to seal the side trim strip and the exterior trim panel. The snap-fit ​​member and the first seal are fixedly connected. The exterior trim panel has mounting holes. A portion of the snap-fit ​​member passes through the mounting holes, and the first seal abuts against the exterior trim panel to secure the first seal to the exterior trim panel.

[0006] The first seal is fixed to the exterior panel by snap-fit ​​components. The exterior panel provides mounting holes for the fixing position of the first seal, which improves the installation stability of the first seal and reduces the possibility of deformation or vibration of the first seal between the side trim strip and the exterior panel, thereby improving the NVH performance of the whole vehicle.

[0007] In some embodiments, the exterior trim panel includes an exterior trim panel body. The exterior trim panel body bends and extends toward one side of the side trim strip to form a first flange. A mounting hole extends through the first flange along its thickness direction. The snap-fit ​​member includes a fixing portion and a connecting portion spaced apart. The fixing portion and a first seal are fixedly connected. The connecting portion passes through the mounting hole and abuts the first seal and the first flange.

[0008] The exterior trim panel is bent and extended to form a first flange, which can provide an installation position for the snap-fit ​​component. The connecting part passes through the mounting hole and abuts the first seal and the first flange to clamp the first seal onto the exterior trim panel, which helps to improve the installation strength.

[0009] In some embodiments, the side panel sealing structure further includes a second seal. The second seal extends along the rear edge of the exterior trim panel. The upper end of the second seal is connected to the first seal. The second seal is located on the rear side of the exterior trim panel in the longitudinal direction, and the second seal is at least partially disposed between the side panel and the exterior trim panel of the vehicle. The second seal is used to seal the side panel and the exterior trim panel.

[0010] There is usually a gap between the rear side of the A-pillar area exterior trim panel and the front door of the vehicle. The second seal is installed on the rear side of the exterior trim panel, which can seal the exterior trim panel and the rear and side panels, and also cover the gap between the exterior trim panel and the front door to prevent the gap from leaking out, reduce wind noise in this area, and improve the appearance quality of this area.

[0011] In some embodiments, the exterior trim panel includes an exterior trim panel body. The exterior trim panel body extends rearward in a front-to-back direction to form a second flange. A second seal is provided with a first sealing groove. The sidewall of the first sealing groove has a raised first lip. The second flange is received in the first sealing groove and abuts against the first lip to fix the second seal to the exterior trim panel.

[0012] The second seal can form a tight contact by abutting the first lip and the second flange of the outer trim panel, thereby preventing the second flange from falling out of the sealing groove, making the second seal and the outer trim panel relatively fixed, which helps to improve the stability of the connection between the second seal and the outer trim panel.

[0013] In some embodiments, the second seal has a second lip protruding from the side facing the side panel. The second lip is used to press against the side panel to form a seal.

[0014] The exterior trim panel and the side panel are usually fitted with a clearance. A second lip is provided on the side of the second seal facing the side panel. The second lip can reduce the clearance between the exterior trim panel and the side panel, thereby reducing wind noise in this area and helping to improve the NVH performance of the whole vehicle.

[0015] In some embodiments, the side panel sealing structure further includes a third seal. The third seal extends along the lower edge of the exterior trim panel. The front end of the third seal is for abutting against the front fender of the vehicle, and the rear end of the third seal is connected to the lower end of the second seal. The third seal is located below the exterior trim panel in a vertical direction. The third seal is at least partially disposed between the side panel and the exterior trim panel. The third seal is used to seal the side panel and the exterior trim panel.

[0016] By placing a third seal between the lower side of the exterior trim panel and the side panel to seal this area, wind noise can be reduced, thereby improving the overall NVH performance of the vehicle.

[0017] In some embodiments, the exterior trim panel includes an exterior trim panel body. The exterior trim panel body extends vertically and bends rearward in the front-to-back direction to form a third flange. A third seal is provided with a second sealing groove. The third flange engages with the second sealing groove to secure the third seal to the exterior trim panel.

[0018] The third flange and the second sealing groove work together to snap the third seal and the outer trim panel together, thereby fixing the third seal and the outer trim panel relatively, improving the connection strength between the third seal and the outer trim panel, and enhancing the sealing performance of the third seal at this point.

[0019] In some embodiments, the third seal extends vertically to cover the third flange. The side of the third seal away from the outer trim panel is connected to the side panel.

[0020] By extending the third seal along the vertical direction to cover the third flange of the exterior panel, the side panel can also be concealed, improving the appearance quality of this area.

[0021] In some embodiments, the first seal, the second seal, and the third seal are integrally formed.

[0022] By molding the first, second, and third seals into a single piece, the seams between the seals can be reduced, which helps to improve sealing performance, thereby improving the appearance and reducing processing and management costs.

[0023] One embodiment of this application provides a vehicle. The vehicle includes a side sealing structure as described in any of the above embodiments. Attached Figure Description

[0027] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Embodiments of this application provide a side panel sealing structure, including an exterior trim panel, a first seal, and a snap-fit ​​member. The first seal is at least partially disposed between a side trim strip and the exterior trim panel of a vehicle. The lower end of the first seal extends to the front fender of the vehicle. The first seal is used to seal the side trim strip and the exterior trim panel. The snap-fit ​​member and the first seal are fixedly connected. The exterior trim panel has mounting holes. A portion of the snap-fit ​​member passes through the mounting holes, and the first seal abuts against the exterior trim panel to secure the first seal to the exterior trim panel.

[0029] The first seal is fixed to the exterior panel by snap-fit ​​components. The exterior panel provides mounting holes for the fixing position of the first seal, which improves the installation stability of the first seal and reduces the possibility of deformation or vibration of the first seal between the side trim strip and the exterior panel, thereby improving the NVH performance of the whole vehicle.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please see Figure 1 and Figure 2One embodiment of this application provides a side sealing structure 100 for the A-pillar area of ​​a vehicle. In various embodiments of this application, the up-down direction refers to the up-down direction when the vehicle is in motion, and the front-back direction refers to the front-back direction when the vehicle is in motion.

[0032] The side panel sealing structure 100 includes an exterior trim panel 1, a first seal 2, and a snap-fit ​​member 3. The first seal 2 is at least partially disposed between the side trim strip 4 and the exterior trim panel 1 of the vehicle. The lower end of the first seal 2 extends to the front fender 8 of the vehicle. The first seal 2 is used to seal the side trim strip 4 and the exterior trim panel 1. The snap-fit ​​member 3 and the first seal 2 are fixedly connected. The exterior trim panel 1 is provided with a mounting hole 101. A portion of the snap-fit ​​member 3 passes through the mounting hole 101 and abuts against the first seal 2 and the exterior trim panel 1 to fix the first seal 2 to the exterior trim panel 1.

[0033] The first seal 2 is fixed to the outer trim panel 1 by the snap-fit ​​component 3. The outer trim panel 1 provides mounting holes 101 for fixing the first seal 2, which improves the installation stability of the first seal 2 and reduces the possibility of deformation or vibration of the first seal 2 between the side trim strip 4 and the outer trim panel 1, thereby improving the NVH performance of the whole vehicle.

[0034] Please see Figure 3 In some embodiments, the exterior trim panel 1 includes an exterior trim panel body 10. The exterior trim panel body 10 is bent and extended toward the side trim strip 4 to form a first flange 11. A mounting hole 101 extends through the first flange 11 along its thickness direction. The snap-fit ​​member 3 includes a fixing portion 31 and a connecting portion 32 spaced apart. The fixing portion 31 is fixedly connected to the first seal 2. The connecting portion 32 passes through the mounting hole 101 and abuts the first seal 2 and the first flange 11.

[0035] The exterior trim panel 1 is bent and extended to form a first flange 11. The first flange 11 provides an installation position for the snap-fit ​​member 3. The connecting part 32 passes through the mounting hole 101 and abuts against the first seal 2 and the first flange 11 to secure the first seal 2 to the exterior trim panel 1, thereby improving installation strength. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 The connecting part 32 may be provided with a stop structure, which is used to stop the connecting part 32 from exiting the mounting hole 101.

[0036] Please see Figure 1 and Figure 2 In some embodiments, the side panel sealing structure 100 further includes a second seal 5. The second seal 5 extends along the rear edge of the outer trim panel 1. The upper end of the second seal 5 is connected to the first seal 2. The second seal 5 is located on the rear side of the outer trim panel 1 in the front-rear direction, and the second seal 5 is at least partially disposed between the side panel 6 and the outer trim panel 1 of the vehicle. The second seal 5 is used to seal the side panel 6 and the outer trim panel 1.

[0037] There is usually a gap between the rear side of the A-pillar area exterior trim panel 1 and the front door of the vehicle. The second seal 5 is installed on the rear side of the exterior trim panel 1, which can seal the exterior trim panel 1 and the rear and side panels 6, and also cover the gap between the exterior trim panel 1 and the front door, preventing the gap from leaking out, reducing wind noise in this area, and improving the appearance quality of this area.

[0038] Please see Figure 5 In some embodiments, the exterior trim panel 1 includes an exterior trim panel body 10. The exterior trim panel body 10 extends rearward in a front-to-back direction to form a second flange 12. The second seal 5 is provided with a first sealing groove 501. The sidewall of the first sealing groove 501 has a protruding first lip 502. The second flange 12 is accommodated in the first sealing groove 501 and abuts against the first lip 502 to fix the second seal 5 and the exterior trim panel 1 together.

[0039] The second seal 5 can form a tight contact by abutting the first lip 502 and the second flange 12 of the outer trim panel 1, thereby preventing the second flange 12 from falling out of the sealing groove, so that the second seal 5 and the outer trim panel 1 are relatively fixed, which helps to improve the stability of the connection between the second seal 5 and the outer trim panel 1.

[0040] In some embodiments, the second seal 5 has a second lip 503 protruding from the side facing the side panel 6. The second lip 503 is used to press against the side panel 6 to form a seal.

[0041] The exterior trim panel 1 and the side panel 6 are usually fitted with a clearance. A second lip 503 is provided on the side of the second seal 5 facing the side panel 6. The second lip 503 can reduce the clearance between the exterior trim panel 1 and the side panel 6, thereby reducing wind noise in this area and helping to improve the NVH performance of the whole vehicle.

[0042] like Figure 5 In the embodiment shown, there is an interference between the first lip 502 and the second flange 12, and there is also an interference between the second lip 503 and the side panel 6. The embodiments of this application do not limit the interference at these two locations, and it is generally between 0.5mm and 1.5mm.

[0043] Please see Figure 1 and Figure 2 In some embodiments, the side panel sealing structure 100 further includes a third seal 7. The third seal 7 extends along the lower edge of the outer trim panel 1. The front end of the third seal 7 is used to abut against the front fender 8 of the vehicle, and the rear end of the third seal 7 is connected to the lower end of the second seal 5. The third seal 7 is located on the lower side of the outer trim panel 1 in the vertical direction. The third seal 7 is at least partially disposed between the side panel 6 and the outer trim panel 1. The third seal 7 is used to seal the side panel 6 and the outer trim panel 1.

[0044] By placing the third seal 7 between the lower side of the exterior trim panel 1 and the side panel 6 to seal this area, wind noise can be reduced, thereby improving the overall NVH performance of the vehicle.

[0045] Please see Figure 6 In some embodiments, the exterior trim panel 1 includes an exterior trim panel body 10. The exterior trim panel body 10 extends vertically and bends backward in the front-to-back direction to form a third flange 13. The third seal 7 is provided with a second sealing groove 701. The third flange 13 is engaged with the second sealing groove 701 to fix the third seal 7 and the exterior trim panel 1 together.

[0046] The third flange 13 and the second sealing groove 701 work together to snap the third sealing element 7 and the outer trim panel 1 together, thereby fixing the third sealing element 7 and the outer trim panel 1 relatively, improving the connection strength between the third sealing element 7 and the outer trim panel 1, and enhancing the sealing performance of the third sealing element 7 at this point.

[0047] In some embodiments, the third seal 7 extends vertically to cover the third flange 13. The side of the third seal 7 away from the outer trim panel 1 is connected to the side panel 6.

[0048] By extending the third seal 7 in the vertical direction to cover the third flange 13 of the outer trim panel 1, the side panel 6 can also be concealed, thus improving the appearance quality of this area.

[0049] like Figure 6 As shown, a doghouse structure 9 is typically provided between the outer trim panel 1 and the side panel 6 to connect them, and is generally located on the third flange 13. By extending the third seal 7 vertically to cover the third flange 13 of the outer trim panel 1, the doghouse structure 9 can be further concealed. Since the doghouse structure 9 is concealed by the third seal 7, its structure can be designed more simply, thereby simplifying the mold structure of the doghouse structure 9.

[0050] Please see Figure 2 In some embodiments, the first seal 2, the second seal 5, and the third seal 7 are integrally formed.

[0051] By integrally molding the first seal 2, the second seal 5, and the third seal 7, the seams between the seals can be reduced, which helps to improve the sealing performance, thereby improving the appearance, and also reducing processing and management costs.

[0052] Please see Figure 7 One embodiment of this application provides a vehicle 200. The vehicle 200 includes a side sealing structure 100 as described in any of the above embodiments.

[0053] Since vehicle 200 includes all embodiments of all technical solutions of the above-mentioned side sealing structure 100, it has at least all the beneficial effects brought by all the above embodiments, which will not be described in detail here.
