Abstract

The utility model relates to an automobile skylight edge-covered PU extending structure which comprises a front PU edge-covered edge connected with front skylight glass and a rear PU edge-covered edge connected with rear skylight glass, wherein PU bosses integrally extend backwards from the left side and the right side of the rear end of the front PU edge-covered edge, an outer side sealing strip and a corner sealing element are connected with the periphery of the rear PU edge-covered edge, the outer side sealing strip is connected with the left side edge and the right side edge of the PU edge-covered edge, the corner sealing element is matched with the front end of the outer side sealing strip and is connected with front corners on the left side and the right side of the rear PU edge-covered edge, and a sealing concave circular bead correspondingly matched with the PU bosses is arranged on the outer side of the front end of the corner sealing element. The structure is simple, the sealing effect between the front glass and the rear glass is good, and the service life is long.

Description

Skylight covering PU (polyurethane) extending structure for automobile

Technical Field

The utility model relates to the technical field of skylights, in particular to an automobile skylight edge-covering PU extending structure.

Background

In the existing panoramic sunroof, PU wrapping edges are wrapped outside front glass and rear glass, and sealing strips are externally connected to the wrapping edges and used for achieving sealing matching between the side edges of the glass and a vehicle body and between the front glass and the rear glass. However, because the corners of the front glass and the rear glass are arc-shaped, the wrapping edges are necessarily arc-shaped, if the existing PU wrapping edges are arranged along the periphery of the glass and the sealing strips are arranged outside the PU wrapping edges, a hollow part is inevitably formed outside the middle matching part of the front glass and the rear glass, the sealing effect is directly influenced, and the water leakage problem is easy to occur.

Disclosure of Invention

The utility model provides the PU extending structure for the edge covering of the automobile skylight, which has the advantages of simple structure, good sealing effect between the front glass and the rear glass and long service life.

The technical scheme adopted by the utility model is as follows: the utility model provides a skylight bordures PU and extends structure, includes that the disjunctor bordures in skylight glass's preceding PU in the front and bordures with skylight glass's back PU in the back and bordures its characterized in that: preceding PU bordures the rear end left and right sides and all extends towards the back an organic whole and has the PU boss, and back PU bordures periphery joint outside sealing strip and corner sealing member, and the outside sealing strip joint is on PU bordured left and right sides limit, and corner sealing member cooperation outside sealing strip front end and joint are in the angle department before the PU bordures the left and right sides of back, and the front end outside of corner sealing member sets up the sealed concave circular bead that corresponds cooperation PU boss.

The inner side outer angle of the PU boss is arc-shaped, and the inner concave angle of the sealing concave circular bead corresponding to the inner side outer angle of the PU boss is corresponding arc-shaped.

The corner sealing piece inwards extends a middle sealing strip which is jointed at the front end of the PU edge cover at the back and at the rear end of the PU edge cover before sealing and matching.

According to the utility model, the traditional straight line fit sealing between the upper sealing strip of the rear PU edge and the front PU edge is changed into two bosses extending from the left and right at the rear end of the front PU edge and matched with the concave shoulder of the corner sealing element at the corner at the front end of the rear PU edge to realize positioning, limiting, matching, clamping and sealing, so that the sealing device has a good sealing effect and effectively prevents water leakage of a skylight.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

In the figure: the glass comprises front glass 1, rear glass 2, a front PU edge 3, a PU boss 4, a rear PU edge 5, an outer side sealing strip 6, a middle sealing strip 7, a corner sealing element 8 and a sealing concave circular bead 9.

Detailed Description

The following is further described with reference to the accompanying drawings.

FIG. 1 shows: the utility model provides a sunroof bordures PU extension structure, sunroof includes preceding glass 1, back glass 2, preceding glass 1, the disjunctor is moulded plastics respectively in the 2 outsides of back glass has preceding PU to bordure 3 and back PU bordures 5, preceding PU bordures 3 rear end left and right sides and all has PU boss 4 towards integrative extension in the back, back PU bordures 5 side joint outside sealing strip 6, corner sealing member 8 cooperation outside sealing strip 6 front end and joint are bordured 5 left and right sides in back PU and are turned round angle department before, corner sealing member 8's the front end outside sets up the sealed concave circular bead 9 that corresponds cooperation PU boss, corner sealing member extends a joint inwards and bordures the front end in back PU, the middle sealing strip 7 of PU bordures the rear end before the sealed cooperation.

In this embodiment, the inboard external angle of PU boss is the arc, and the interior fillet of the sealed concave circular bead that the inboard external angle of PU boss corresponds is corresponding arc, and the arc corresponds the cooperation and can further improve sealed joint performance and spacing joint stability.

Claims

1. The utility model provides a skylight bordures PU and extends structure, includes that the disjunctor bordures in skylight glass's preceding PU in the front and bordures with skylight glass's back PU in the back and bordures its characterized in that: preceding PU bordures the rear end left and right sides and all extends towards the back an organic whole and has the PU boss, and back PU bordures periphery joint outside sealing strip and corner sealing member, and the outside sealing strip joint is on PU bordured left and right sides limit, and corner sealing member cooperation outside sealing strip front end and joint are in the angle department before the PU bordures the left and right sides of back, and the front end outside of corner sealing member sets up the sealed concave circular bead that corresponds cooperation PU boss.

2. The automobile skylight edge-covering PU extending structure of claim 1, wherein: the inner side outer angle of the PU boss is arc-shaped, and the inner concave angle of the sealing concave circular bead corresponding to the inner side outer angle of the PU boss is corresponding arc-shaped.
