As shown in Figure 1, Figure 2 and shown in Fig. 5, the both ends of weather strip ontology 1 front end with two spring leafs 2 respectively in the present embodiment
It is affixed, and the rear end of spring leaf 2 is used to be fixed in the guide rail of skylight by fixed frame 3.It when in use, will using fixed frame 3
The rear end of spring leaf 2 is fixed in guide rail；After the glass assembly with glass of skylight is opened, the front end of spring leaf 2 drives weather strip ontology 1
It is upturned, to adjust the flowing of outside air and in-vehicle air, and realizes keeping out the wind, dropping the wind effect of making an uproar for weather strip ontology 1.And
The both ends of middle weather strip ontology 1 are hit by a bullet by rotational pin and the hinged connection type of guide rail, the present embodiment compared with the prior art
The rear end of reed 2 is fixed in guide rail, i.e., the both ends of weather strip ontology 1 are connect by spring leaf 2 with guide rail, so that weather strip sheet
The vibration natural frequency of body 1 is effectively improved, because there may be noises for the vibration of weather strip ontology 1 when reducing vehicle driving
Risk, and further enhance the ability that this day draught bead reduction wind is made an uproar.
As shown in Figure 1, Figure 2 and shown in Fig. 5, the rear end of spring leaf 2 is equipped with through-hole 21 in the present embodiment, and fixed frame 3 has limit
Slot 31, and the upper side wall of limiting slot 31 is equipped with retention bead 32, the rear end of spring leaf 2 is limited for being inserted in limiting slot 31
Protrusion 32 is in through-hole 21.When in use, fixed frame 3 is fixed in the guide rail of skylight, and by the rear end of spring leaf 2
It is inserted into limiting slot 31, and makes retention bead 32 in through-hole 21, to utilize the left and right sidewall limited spring of limiting slot 31
It moves in left-right direction the rear end of piece 2；And utilize the mating reaction of retention bead 32 and through-hole 21, the rear end of limited spring piece 2
It moves along the longitudinal direction；And moved along the vertical direction using the rear end of the upper side wall of limiting slot 31 and guide rail limited spring piece 2, from
And realize and the rear end of spring leaf 2 is fixed in guide rail using fixed frame 3, traditional centre part, such as rotational pin are eliminated, is dropped
The risk of noise is generated when low rotation, and the system first-order modal vibration frequency of entire weather strip can be improved.Meanwhile as schemed
Shown in 5, the front side wall of retention bead 32 is equipped with guiding surface 321 in the present embodiment.In an assembling process, fixed frame 3 is consolidated
After being scheduled on guide rail, the rear end of spring leaf 2 is inserted back into limiting slot 31, before the rear end of spring leaf 2 and retention bead 32
Side wall leans, and smoothly slides backward along guiding surface 321, until the through-hole 21 of spring leaf 2 is moved to and retention bead 32
Opposite position, retention bead 32 is in through-hole 21.In addition, as shown in figure 5, fixed frame 3 is in retention bead in the present embodiment
32 side is equipped with deformation notch 33；Specifically fixed frame 3 is equipped with deformation in the left and right side of retention bead 32 and back side edge
Notch 33, to reduce the bonding strength of the ontology of retention bead 32 and fixed frame 3, and effectively enhancing retention bead 32 is upturned
Deformability.The rear end of above-mentioned spring leaf 2 and the antetheca of retention bead 32 lean, and slide backward along guiding surface 321
In the process, retention bead 32 will be upturned, to guarantee that the rear end of spring leaf 2 can be smoothly inserted back into limiting slot 31, until
The through-hole 21 of spring leaf 2 is corresponding with retention bead 32, and retention bead 32 resets downwards and in the through-hole 21 of spring leaf 2；
At this point, the rear wall of retention bead 32 moves forward the rear end of effective limited spring piece 2, and the rear wall of limiting slot 31 will have
The rear end of effect limited spring piece 2 moves backward.The rear end of the left and right sides wall energy limited spring piece 2 of limiting slot 31 in the present embodiment
It in left and right directions and in suitable manufacturing tolerance will not play or movement.
The material of weather strip ontology 1 is polypropylene in the present embodiment, guarantee weather strip ontology 1 have required rigidity and
While intensity, its manufacturing cost is reduced.Weather strip ontology 1 specifically passes through mold injection by plastics PP-GF50 in the present embodiment
It forms, manufacturing cost is lower, and corrosion resistance is strong, forms simple and easily controllable.Weather strip ontology 1 is having in the present embodiment
There is the above-mentioned convex block 11 that keeps out the wind equal with the thickness at wind-guiding notch 12.
As depicted in figs. 1 and 2, the both ends of weather strip ontology 1 are equipped with reinforcement convex ribs 13 in the present embodiment, to effectively improve gear
The rigidity of wind ontology 1, and meet requirement of the client to rigidity.
As shown in Figure 1, side buffer stopper 4 is installed on the antetheca of weather strip ontology 1 in the present embodiment, it is total in the glass of skylight
At closing, and during weather strip ontology 1 moves down, side buffer stopper 4 is in contact with roof, straight to avoid weather strip ontology 1
It connects and is contacted firmly with roof.Meanwhile as shown in Figure 1, the bottom of weather strip ontology 1 is equipped with lower buffer stopper 5 in the present embodiment, in day
During the glass assembly with glass of window is closed, and weather strip ontology 1 moves down, lower buffer stopper 5 is in contact with preceding rhone, to avoid
Weather strip ontology 1 is directly contacted with preceding rhone firmly.
As shown in figure 3, the surface of the rear wall for the convex block 11 that keeps out the wind in the present embodiment is in tapered plane.It is above-mentioned in the present embodiment to lead
Stream interface 111 obtains proper height and radius of curvature by CAE analysis, alleviates the weight of weather strip ontology 1, also ensures simultaneously
The design frequency of this day draught bead is able to satisfy the requirement that client need to be greater than first-order modal 30Hz.
In the present embodiment the front end of spring leaf 2 by plastic technique with weather strip ontology 1 is affixed is integrally formed, its rear end is straight
It patches in above-mentioned fixed frame 3, eliminates traditional rotation pin assembly, so that the assembly of weather strip ontology 1 and fixed frame 3 is more
Securely, it can effectively improve the vibration fixed frequency of weather strip.
Above-mentioned day draught bead in the present embodiment, for dropping low wind noise when automobile skylight glass is opened, optimization it is interior with
Ambient atmos convection current is a kind of light-weighted day draught bead structure of low cost.The day draught bead of such plastics compares metal
Weather strip structure has the advantages that at low cost, lightweight and corrosion resistance are higher.Meanwhile day draught bead is not in the present embodiment
It needs to rotate in fixed frame 3 using rotating dog, support arm in the prior art is replaced with spring leaf 2, and weather strip ontology 1 is not
Most spring leaf 2 is coated again, effectively reduces the weight of product, is improved product vibration frequency, is reduced vehicle driving
There may be the risks of noise by Shi Zhendong.And the present embodiment optimizes the weather strip of common great-wall shaped structure, it can
It is enough simpler, stable, and effectively optimize gas flowing.The present embodiment is by the material of weather strip ontology 1 by traditional metal
Or PA66-CF30 replaces with above-mentioned PP-GF50, and while guaranteeing required stiffness and strength, weather strip ontology 1 is effectively reduced
Cost.Day draught bead meets requirement of the client to the noise reduction of weather strip, rigidity and vibration frequency in the present embodiment, and effectively
Ground reduces development cost, alleviates the total weight of retractable roof system.
In conclusion the utility model effectively overcomes various shortcoming in the prior art and has high industrial exploitation value
Value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
