Description
Technical Field
The utility model relates to an automobile skylight structure, two seal structure of back glass PU water drainage tank specifically say so.
Background
For the purposes of openness and aesthetic design increase, the existing automobile widely uses a panoramic sunroof, the panoramic sunroof is divided into front glass and rear glass, and the gap space between the front glass and the rear glass must meet various requirements such as sealing performance and the like. Add between preceding, back glass in current skylight structure and establish the sealing strip to set up PU water drainage tank under the sealing strip, via ponding under the sealing strip seepage, realize not having leaking with dredging, nevertheless when in-service use, because the automobile in the driving process inevitable have instantaneous speed change's such as acceleration, emergency brake the condition, easily lead to the PU water drainage tank in the water spills from back glass PU water drainage tank, have certain sealed problem.
Disclosure of Invention
The utility model provides a compact structure, firm can prevent effectively that instantaneous variable speed from leading to PU water drainage tank to spill ponding, two seal structure of back glass PU water drainage tank that sealing performance is good.
The utility model adopts the technical proposal that: the utility model provides a two seal structure of back glass PU water drainage tank which characterized in that: the rear sealing device comprises a front glass support, a rear glass support, a middle sealing strip, a rear sealing strip and a rear glass PU strip, wherein the middle sealing strip is connected to the outer side of the front end of the rear glass support and is in a state that the front part is sealed and tightly abutted against the rear end of the front glass support, the lower end of the front part of the front glass support is connected with the front part of the rear glass PU strip, the rear part of the rear glass PU strip extends into the lower part of the rear glass support, the rear end of the rear glass PU strip is connected with the rear sealing strip, the front part of the rear sealing strip is tightly abutted against the inner side of the front end of the rear glass.
Further, the back sealing strip includes joint end and hollow crimping end, and the joint end is at glass PU strip rear portion behind the bayonet socket joint, and hollow crimping end elastic deformation supports the crimping back glass support front end inboard.
Furthermore, a rigid bayonet strip is embedded in the bayonet at the clamping end or the bayonet is integrally formed.
Furthermore, the front part of the middle sealing strip is tightly pressed against the rear end of the front glass bracket through the hollow compression joint section.
Furthermore, the middle sealing strip is connected to the outer side of the front end of the rear glass support and is in a state that the front part of the middle sealing strip is tightly pressed against the PU strip of the rear glass in a sealing mode.
Furthermore, the top of the rear sealing strip abuts against the lower side of the rear glass support.
The utility model discloses a prevent that water from spilling from back glass PU when the car from emergency braking in the driving process, joint back sealing strip on back glass PU strip, well sealing strip and back sealing strip combination form closed chamber, can prevent effectively that instantaneous speed change from resulting in spilling out ponding in the back glass PU strip, the leakproofness chamber, it is extensive to use, the suitability is strong, can follow different environment and arrange different shapes; and the back sealing strip passes through rigidity bayonet strip joint back glass PU strip, and the joint power is big, is favorable to further improving sealing performance.
