Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle accessories, in particular to a sealing structure. Background Art
[0002] At present, sealing structures such as sealing strips are generally provided between the doors and the body of a vehicle to ensure sealing inside the vehicle and play a role in waterproofing, dustproofing and sound insulation.
[0003] In the prior art, the sealing structure consists of two separate sealing parts, one on the door and one on the vehicle body. When the door is closed relative to the vehicle body, the two separate sealing parts contact and abut against each other, achieving a tight seal. However, over time, the sealing structure gradually deforms due to repeated contact and friction between the two sealing parts during door opening and closing, weakening the abutment and reducing the sealing performance of the door. Furthermore, as the abutment between the two sealing parts weakens, the door becomes more likely to wobble relative to the vehicle body when the vehicle drives over potholes, affecting the stability of the door's closure. Utility Model Content
[0004] The purpose of the utility model is to provide a sealing structure that can effectively ensure the sealing between the vehicle door and the vehicle body, and can limit the vehicle door to prevent the vehicle door from shaking inside and outside relative to the vehicle body.

[0034] This embodiment provides a sealing structure. Figures 1 to 2 As shown, the sealing structure is provided between the vehicle body 3 and the vehicle door 4, with glass 5 provided on the outer side of the vehicle door 4. The sealing structure comprises a first sealing body 1 and a second sealing body 2. The first sealing body 1 is fixedly provided on the vehicle body 3 and has a first sealing end face 11 facing the vehicle door 4. The first sealing end face 11 defines an arcuate sealing groove 12. The second sealing body 2 is fixedly provided on the vehicle door 4 and has a second sealing end face 21 facing the vehicle body 3. The second sealing end face 21 is provided with an arcuate sealing head 22. When the vehicle door 4 is closed relative to the vehicle body 3, the first sealing end face 11 abuts the second sealing end face 21, and the arcuate sealing head 22 extends into the arcuate sealing groove 12 and abuts against the wall of the arcuate sealing groove 12.
[0035] In this embodiment, when the vehicle door 4 is closed relative to the vehicle body 3, the first sealing end face 11 on the vehicle body 3 abuts the second sealing end face 21 on the vehicle door 4, while the arcuate sealing head 22 abuts the groove wall of the arcuate sealing groove 12, forming two seals between the first sealing end face 11 and the second sealing end face 21, and between the arcuate sealing head 22 and the arcuate sealing groove 12. Even if the first sealing end face 11 or the second sealing end face 21 deforms after prolonged use, the cooperation between the arcuate sealing head 22 and the arcuate sealing groove 12 still ensures a two-stage seal between the vehicle body 3 and the vehicle door 4, effectively enhancing the sealing performance. The arcuate sealing head 22 and the arcuate sealing groove 12 are both configured in an arc shape. This configuration ensures that the arcuate sealing head 22 can contact and extend into the arcuate sealing groove 12 more smoothly and reliably, avoiding any jamming. In addition, the cooperation between the arc-shaped sealing head 22 and the arc-shaped sealing groove 12 can also play a reliable limiting role on the vehicle door 4, preventing the vehicle door 4 from shaking inward and outward relative to the vehicle body 3, and effectively ensuring the stability of the vehicle door 4 when it is closed.
[0036] In this embodiment, the first sealing body 1 and the second sealing body 2 are both made of elastic material. This allows the arcuate sealing head 22 to be squeezed and deformed to enter and abut against the arcuate sealing groove 12 during contact between the arcuate sealing head 22 and the arcuate sealing groove 12.
[0037] Exemplarily, the material of the first sealing body 1 and the second sealing body 2 is set to be rubber.
[0038] In this embodiment, a through-hole 13 is defined at the bottom of the arcuate sealing groove 12, and a threaded hole is defined in the vehicle body 3. A screw 6 is threadedly connected through the through-hole 13. Specifically, the screw 6 secures the first sealing body 1 to the vehicle body 3, resulting in a simple and reliable structure. Furthermore, the through-hole 13, located at the bottom of the arcuate sealing groove 12, allows the screw 6 to be embedded within the arcuate sealing groove 12, preventing it from being exposed, thus maintaining aesthetics and preventing rust from occurring.
[0039] In this embodiment, a relief groove 14 is provided at the bottom of the arcuate sealing groove 12. The screw head of the screw 6 is located within the relief groove 14, and the through hole 13 is connected to the relief groove 14. The relief groove 14 provides space for the screw head of the screw 6, preventing the screw head from extending outward and occupying the space of the arcuate sealing groove 12.
[0040] In this embodiment, a metal bead 15 is provided in the avoidance groove 14. The metal bead 15 is provided so that the metal bead 15 is clamped in the avoidance groove 14. When the screw 6 is tightened, the first sealing body 1 is compressed by the metal bead 15, thereby achieving a more reliable and stable fixing effect on the first sealing body 1.
[0041] In this embodiment, a first engaging claw 16 is provided on a side of the first sealing body 1 corresponding to the exterior of the vehicle body 3. The first engaging claw 16 bends and extends toward the corresponding vehicle body 3 and engages the vehicle body 3. The provision of the first engaging claw 16 effectively blocks the gap between the exterior of the vehicle body 3 and the first sealing body 1, further ensuring the seal between the exterior of the vehicle body 3 and the first sealing body 1.
