A kind of automobile front door guide rail sealed strip
Technical field
The present invention relates to a kind of sealed strip, particularly a kind of automobile front door guide rail sealed strip.
Background technology
Now commercially automobile front door guide rail sealed strip, comprise bar on Qianmen, Shang Tiao one end, described Qianmen is connected with the front door pillar bar of extension downwards, the described front door pillar bar the other end is connected with and the Qianmen vertical bar that front door pillar bar extends in the same way, and on Qianmen, bar the other end place is connected with the Qianmen side bar parallel with described front door pillar bar. On Qianmen there is gap in junction between bar and side, Qianmen bar, due to the existence in gap, thus the stopping property causing sealed strip reduces, and waterproof and dustproof, the windproof effect made an uproar just weaken greatly, and can obviously see due to Qianmen guide rail sealed strip, seriously affect the aesthetics of outward appearance.
Summary of the invention
It is an object of the invention to solve above-mentioned the deficiencies in the prior art, it is provided that a kind of good sealing effect and automobile front door guide rail sealed strip attractive in appearance.
In order to realize above-mentioned purpose, a kind of automobile front door guide rail sealed strip designed by the present invention, comprise bar on Qianmen, Shang Tiao one end, described Qianmen is connected with the front door pillar bar of extension downwards, the described front door pillar bar the other end is connected with and the Qianmen vertical bar that front door pillar bar extends in the same way, and on Qianmen, the place's seamless link of the bar the other end has the Qianmen side bar parallel with described front door pillar bar.
The specific form of bar on Qianmen, on described Qianmen, bar comprises bar support bar, described upper bar support bar two ends are provided with the first holding division, wherein the first U-shaped setting of holding division of one end and be embedded with the first U-shaped aluminium band therein, the inner side-wall of described the first holding division being embedded with the first aluminium band is provided with some assembling teeth, deviating from the first holding division side on described upper bar support bar and be provided with some first sealing lip limits, the end points being provided with the first holding division of the first aluminium band is provided with outward extending 2nd sealing lip limit;
The specific form of side, Qianmen bar, side, described Qianmen bar comprises side bar support bar, and support bar side, described side article is provided with some 2nd holding divisions, and another side is provided with some 3rd sealing lip limits;
Away from be embedded with the first aluminium band the first holding division upper article of support bar on the first sealing lip limit on one end and between the 3rd sealing lip limit on the right side of the support bar of side article by a block rubber injection moulding mold pressing seamless link. Connected by block rubber, it is possible to play the effect of seamless link, strengthen the Resisting fractre intensity of junction simultaneously, extend the work-ing life of sealed strip.
Preferably, described block rubber is TPV material.
Further, with cashmere-planted layer on described first sealing lip limit, the 2nd sealing lip limit and the 3rd sealing lip limit. Cashmere-planted layer can play waterproof and dustproof and the anti-effect made an uproar.
Preferably, described cashmere-planted layer heat bonding is on described first sealing lip limit, the 2nd sealing lip limit and the 3rd sealing lip limit.
Preferably, described upper article of support bar, side article support bar, the first holding division, the 2nd holding division, the first sealing lip limit, the 2nd sealing lip limit and the 3rd sealing lip limit are EPDM material.
A kind of automobile front door guide rail sealed strip that the present invention obtains, its technique effect is: 1, bar and the bar seamless link of side, Qianmen on Qianmen, it is to increase the stopping property of sealed strip, the successful of waterproof and dustproof, noise windproof, anti-, the outward appearance of seamless link is more attractive in appearance, it is to increase comfort level time by bus; 2, adopt the combination of TPV material and EPDM material, it is possible to improve the Resisting fractre intensity of junction, increase work-ing life.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, a kind of automobile front door guide rail sealed strip provided by the invention, comprise bar 1 on Qianmen, on described Qianmen, bar 1 one end is connected with the front door pillar bar 2 of extension downwards, described front door pillar bar 2 the other end is connected with and the Qianmen vertical bar 3 that front door pillar bar 2 extends in the same way, and on Qianmen, the place's seamless link of bar 1 the other end has the Qianmen side bar 4 parallel with described front door pillar bar 2.
As shown in Figure 3, the specific form of bar 1 on Qianmen, on described Qianmen, bar 1 comprises bar support bar 5, described upper bar support bar 5 two ends are provided with the first holding division 6, wherein the first U-shaped setting of holding division of one end and be embedded with the first U-shaped aluminium band 7 therein, the inner side-wall of described the first holding division 6 being embedded with the first aluminium band 7 is provided with some assembling teeth 8, deviating from the first holding division 6 side on described upper bar support bar 5 and be provided with some first sealing lip limits 9, the end points being provided with the first holding division 6 of the first aluminium band 7 is provided with outward extending 2nd sealing lip limit 10;
As shown in Figure 4, the specific form of side, Qianmen bar 4, side, described Qianmen bar 4 comprises side bar support bar 11, and support bar 11 side, described side article is provided with some 2nd holding divisions 12, and another side is provided with some 3rd sealing lip limits 13;
As shown in Figure 2, away from be embedded with the first aluminium band 7 the first holding division 6 upper article of support bar 5 on the first sealing lip limit 9 on one end and between the 3rd sealing lip limit 13 on the right side of side article support bar 11 by a block rubber 14 injection moulding mold pressing seamless link. Connected by block rubber 14, it is possible to play the effect of seamless link, strengthen the Resisting fractre intensity of junction simultaneously, extend the work-ing life of sealed strip.
In the present embodiment, described block rubber 14 is TPV material.
On described first sealing lip limit 9, the 2nd sealing lip limit 10 and the 3rd sealing lip limit 13, heat bonding has cashmere-planted layer 15. Cashmere-planted layer 15 can play waterproof and dustproof and put the effect made an uproar.
In the present embodiment, described upper article of support bar 5, side article support bar 11, first holding division 6, the 2nd holding division 12, first sealing lip limit 9, the 2nd sealing lip limit 10 and the 3rd sealing lip limit 13 are EPDM material.
A kind of automobile front door guide rail sealed strip that the present invention obtains, its technique effect is: 1, bar 1 and bar 4 seamless link of side, Qianmen on Qianmen, it is to increase the stopping property of sealed strip, the successful of waterproof and dustproof, noise windproof, anti-, the outward appearance of seamless link is more attractive in appearance, it is to increase comfort level time by bus; 2, adopt the combination of TPV material and EPDM material, it is possible to improve the Resisting fractre intensity of junction, increase work-ing life.
