The vehicle window sealing band
Technical field
The utility model relates to automotive sealant, relates in particular to a kind of vehicle window sealing band.
Background technology
In order to keep car body in-to-in leak tightness, be provided with the vehicle window sealing band between automotive glazing and the glass installation groove, sealing band sealing effectiveness such as bad, not only sound insulation noise control effect is bad, and dust etc. also enters in the car body easily, and existing sealing band designs for square in the corner of vehicle window.In China Patent No. is ZL00249561.9, name is called the connection structure that discloses the corner of a kind of sealing band and vehicle window in the patent documentation of " a kind of angle structure of automotive window guide groove sealing strip ", it is that the sealing band that will laterally place is connected by a joint angle with the vertical sealing band of placing, this joint angle is a structure of right angle tyoe, but sternly do not produce air-flow noise because the production technology error of square design-calculated sealing band joint angle and vehicle window often causes sealing band and wind glass to be fitted, and influence the overall acoustic seal characteristic of automobile.
Summary of the invention
The utility model provides a kind of sealing band of good sealing effect, and having solved existing sealing band and vehicle window corner is that sealing band and the wind glass applying that square caused sternly do not produce air-flow noise, and influences the problem of the overall acoustic seal characteristic of automobile.
Above technical matters solves by following technical proposal: a kind of vehicle window sealing band, comprise joint angle and the sealing band body that is connected the joint angle two ends, and described joint angle is a circular arc.Circular arc design makes wind glass and sealing band big in the joint face of corner, thereby low to the error requirements that adds man-hour.
As preferably, all be provided with on sealing band body and the joint angle and hold the groove that the glass for vehicle window edge is used, on the sidewall of described groove, be provided with the sealing wing.Improve sealing effectiveness.
As preferably, on two sidewalls of described groove, all be provided with the sealing wing, the described sealing wing is located at the free end of described trenched side-wall.From both sides wind glass is sealed, sealing effectiveness is better.
As preferably, on the joint face of described sealing band body, be provided with raised line." joint face " be sealing band and the surface that vehicle window guide groove sidewall is connected when being meant running condition, makes sealing band more firm with being connected of vehicle window guide groove.
As preferably, described raised line is along the longitudinal extension of sealing band body." vertically " is meant the direction that parallels with the cross-sectional plane of sealing band body.
Preferred as another, described raised line is along the horizontal expansion of described sealing band body.After preventing that viscose glue between sealing band and the vehicle window guide groove is aging, the sealing property decline between sealing band and the vehicle window guide groove.
The utlity model has following advantage, adopt the design of fillet type in the corner of sealing band, not only make outward appearance more attractive in appearance, increased the area of contact of sealing band corner and vehicle window simultaneously, make sealing band under the state of distortion, also can play good sealing function, improved the overall acoustic seal characteristic of car door.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment one, referring to Fig. 1, a kind of vehicle window sealing band, comprise joint angle 1 and the sealing band body 2 that is connected the joint angle two ends, joint angle 1 is a circular arc, the radius of the downside arc surface 11 of joint angle 1 is 3 centimetres, on the leading flank of sealing band body 2 and trailing flank, all be provided with raised line 3, the leading flank of sealing band body 2 and trailing flank when using with vehicle window guide groove 6(referring to Fig. 4) surface that is connected, raised line 3 is along the radially extension of sealing band body 2, on sealing band body 2 and joint angle 1, all be provided with the groove 4 that extends vertically, on the front side wall of groove 4 and rear wall, all be provided with and seal the wing 5.
Sealing the wing 5 referring to Fig. 2 forms towards the groove internal bend for the free end of groove 4 sidewalls.
Referring to Fig. 3, the sealing wing 5 extends vertically.
Embodiment two, referring to Fig. 4, with the difference of embodiment one be that raised line 3 extends axially along sealing band body 2.
Referring to Fig. 5, during use, sealing band body 2 is built in the vehicle window guide groove 6, joint angle 1 is the corner with vehicle window guide groove 6, raised line 3 elasticity are connected on the sidewall of vehicle window guide groove, and the place, slit between vehicle window guide groove 6 and vehicle window sealing band body is coated with lining cement, and vehicle window sealing band and vehicle window guide groove are fixed together, glass for vehicle window 7 is positioned at groove 4, and the sealing wing 5 is close on the glass for vehicle window 7 from the both sides of glass for vehicle window 7.
