The roof glass of the vehicle sunroof may include a single roof glass, and may further include a front roof glass and a rear roof glass. In some scenarios, the sunroof is controlled to be tilted for ventilation purposes, so that air inside and outside the vehicle can be convected through the opening formed during tilting. The embodiment shown in fig. 3 shows a partial structure of a sunroof of a vehicle when a front windshield glass is in a tilted state. When the air flow speed at the opening is high, the air flow speed is mixed with the surrounding air flow with relatively low speed to generate turbulence, and a large vortex structure is formed, so that lasting noise is generated.

Referring to fig. 1 and 2, fig. 1 is a perspective view showing a partial structure of a sunroof for a vehicle according to an exemplary embodiment of the present invention. Fig. 2 shows a cross-sectional view of a vehicle sunroof according to an exemplary embodiment of the present invention. The seal of the front sunroof glass 100 is formed by a first hem 102 of PU material and a seal strip 300, and the seal of the rear sunroof glass 200 is formed by a second hem 202 of PU material. When the front skylight glass 100 is in a closed state, the sealing strip 300 is abutted against the second wrapping edge 202 of the rear skylight glass, so that a sealed structure is formed for water and sound proofing; when the front sunroof glass 100 is in a raised state, the sealing member 300 is separated from the second hem 202 of the rear sunroof glass 200, and an opening is formed through which air can flow convectively. Since different air flows form turbulent vortex structures near the openings, the turbulent vortex structures are improved by arranging the turbulent vortex structures 312 with the saw teeth 314 on the sealing strip 300, so that the noise reduction effect is achieved.

The sealing strip 300 comprises a sealing strip body 302 and a spoiler structure 312 extending along the length direction of the sealing strip body 302, and as shown in the embodiment of fig. 1 and 2, the sealing strip body 302 is provided with a cavity 304 suitable for deformation generated when the sealing strip body abuts against a second edge of the rear skylight glass, so as to seal the skylight glass in a closed state. The spoiler structure 312 is between the weatherstrip body 302 and the second bead 202 of the rear sunroof glass when the front sunroof glass 100 is tilted (as shown in FIG. 3). When the air current flows through the sawtooth through the opening 400, the vortex structure is disassembled through the dispersion of the sawtooth shape, so that the disassembled vortex structure can disappear rapidly. Further, an insert 306 is provided adjacent to the first envelope 102 of the sealing strip body. The insert portion 306 is adapted to fit into the slot 104 on the first skirt 102 for secure attachment to form a sealed structure. Further, the socket 104 is provided with a constriction 106 to interlock with the insert 306, further enhancing the sealing effect.

Fig. 4 is a partial structural view showing a weather strip according to an exemplary embodiment of the present invention. In fig. 4, a plurality of teeth 314 are provided at a lower portion of the spoiler structure near the middle. Further, the spoiler is provided with a support 319 (see fig. 6 and 7) arranged along a length direction thereof, the support 319 supporting the plurality of teeth 314. Fig. 5 and fig. 6 are combined, wherein fig. 5 shows a cross-sectional view along a-a in fig. 4, and fig. 6 shows a cross-sectional view along B-B in fig. 4. The saw teeth 314 and the supporting part 319 may be integrally formed. It can be seen from fig. 5 that the cross section of the integrated structure formed by the saw teeth 314 and the supporting part 319 is an inverted cone, and the cross section at the tooth top 316 is a circular arc, i.e. the tooth top 316 is a horizontal partial cylinder. By means of the circular arc arrangement, the air flow through the position is relatively smooth and does not suddenly change. Fig. 6 shows a cross-sectional view of the support portion 319 of the spoiler structure 312. That is, the serrations 314 are not directly provided on the surface of the sealing tape body 302, but are provided on the spoiler 312 through the supporting portions 319. Through setting up like this, can guarantee the intensity of vortex structure, the vortex structure of also being convenient for simultaneously processing the sealing strip.

Based on a number of experimental results, in some embodiments, serrations 3Height h of 14₁The length d of the tooth top 316 along the length direction of the turbulent flow structure is set to be within the range of 2.2 mm to 2.6 mm₁The maximum length d of the single sawtooth 314 along the length direction of the spoiler structure is set within the range of 5.0 mm to 8.0 mm₂The setting is in the range of 18.0 mm to 22.0 mm, and a good noise reduction effect is achieved.

For example, in some embodiments, the height h of the serrations₁Set in the range of 2.2 mm to 2.4 mm, the length d of the tooth top₁Is set in the range of 5.0 mm to 6.5 mm, and the maximum length d of the sawtooth along the length direction₂Set in the range of 18.0 mm to 20.0 mm; height h of the serrations₁The length d of the tooth top along the length direction is set in the range of 2.3 mm to 2.5 mm₁The maximum length d of the sawtooth along the length direction is set in the range of 6.0 mm to 7.0 mm₂Set in the range of 20.0 mm to 21.5 mm; height h of the serrations₁Is set in the range of 2.4 mm to 2.6 mm, and the length d of the tooth top along the length direction₁The maximum length d of the sawtooth along the length direction is set in the range of 6.5 mm to 8.0 mm₂Is set in the range of 21.0 mm to 22.0 mm.

As a preferred embodiment, as shown in FIG. 7, two adjacent saw teeth pass through a radius R₁The length d of the tooth top 316 along the length direction of the turbulent flow structure is 2 mm of fillet connection₁6.5 mm, the height h of the serrations 314₁Is 2.4 mm, and the maximum length d of a single serration 314₂Is 20.0 mm.

In some embodiments, the height h of the seal strip in the same cross-section as the turbulator structure₂Set to a saw tooth height h₁4.0 to 7.0 times. Not only can guarantee the intensity of vortex structure and be convenient for process, still gained better noise reduction effect. Alternatively, in some embodiments, the height of the sealing strips on the same section as the spoiler structure is set to be 5.0 times, 6.0 times, 6.5 times the height of the serrations.

In order to prevent rainwater from penetrating into the interior of the vehicle body from the sealed structure between the front sunroof glass and the rear sunroof glass, a drain groove 500 is provided below the weather strip and the first hem. Both ends of the drain channel 500 are provided with receiving structures 502 to receive the respective sealing members 600. Therefore, the spoiler structure for improving the turbulent vortex structure is not suitable for being disposed at both ends of the drain groove 500 because of easy interference. In the embodiment shown in fig. 1 and 2, the spoiler structure 312 is not adapted to be arranged at the first position 107 of the first envelope 102. In addition, since the slot 104 of the first edge wrapping 102 needs to be matched with the insertion portion 306 of the sealing strip, if the spoiler structure 312 is disposed at the second position 109 below the slot, the deformation of the slot may be increased due to the self-weight, and the sealing performance between the slot 104 and the insertion portion 306 may be affected. Further, if the flow disturbing structure 312 for noise reduction is provided at the first position 107 and the second position 109, the height of the flow disturbing structure 312 needs to be additionally increased to be suitable for the air flow at the saw tooth contact opening 400, thereby requiring more space for arranging the drain groove 500 and the flow disturbing structure. In addition, if such an arrangement is provided, the amount of adjustment of the roof glass is also affected. Based on the above reasons, the turbulent flow structure is integrated in the sealing strip body, and has the advantages of compact structure, cost saving and the like.

The material that sets up the sealing strip is Ethylene Propylene Diene Monomer (EPDM), has further reduced the cost of vortex structure.
