Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a sunroof frame sealing strip. Background Art

[0002] Existing car sunroofs and car bodies are generally sealed with semi-solid sealants, but the structure of traditional sealing strips is complex, making assembly and replacement difficult. To solve the above problems, the Chinese patent document "A Sealing Strip for Car Sunroofs" (patent application number: 201520551341.8) discloses a sealing strip for car sunroofs that solves the problems of simple assembly and easy replacement. However, after long-term use, the above-mentioned sealing strips still have poor sealing, and their thin cross-section makes them easily folded inward when installed on the vehicle, which in turn causes rain leakage. Utility Model Content

[0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide a skylight frame sealing strip, which improves the sealing performance, avoids folding, and prevents rain leakage.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a skylight frame sealing strip, comprising a rectangular ring-shaped sealing strip body, the sealing strip body comprising a single-bubble sealing strip base, a foaming part is arranged inside the single-bubble sealing strip base, and the cross-section of the single-bubble sealing strip base is triangular, including a horizontal edge located on the top surface, a convex arc edge located on the outside and a concave arc edge located on the inside; the middle part of the horizontal edge extends vertically upward to form a first extension part, and a number of raised parts are arranged relatively on the inner and outer sides of the first extension part; a first lip edge is provided at the bottom of the single-bubble sealing strip base, and the first lip edge is inclined toward the inside; the position of the concave arc edge near the upper end extends horizontally inward to form a second extension part, and a second lip edge and a third lip edge are respectively provided on the upper and lower sides of the free end of the second extension part, the second lip edge is inclined toward the outside, and the third lip edge is inclined toward the inside.

[0005] A further improvement is that a clamping groove is formed between the horizontal edge and the upper adjacent protrusion, and between each two upper and lower adjacent protrusions.

[0006] A further improvement is that the second lip, the first extension portion and the second extension portion form a first opening.

[0007] A further improvement is that the third lip edge, the concave arc edge and the second extension portion form a second opening.

[0008] A further improvement is that a rebound groove is provided at the connection between the third lip and the second extension portion.

[0009] A further improvement is that the raised portions are all arranged to be inclined downward.

[0010] A further improvement is that two protrusions are arranged opposite to each other on the top of the first extension portion, and two protrusions are arranged opposite to each other in the middle portion of the first extension portion.

[0011] A further improvement is that the upper end of the second lip is lower than the upper end of the first extension portion, and a gap is left between the second lip and the raised portion located at the top of the first extension portion.

[0012] A further improvement is that both the inner and outer sides of the single-bubble sealing strip base do not exceed the raised portion.

[0013] A further improvement is that the third lip has the same inclination angle as the first lip, and the lower end of the third lip is higher than the lower end of the first lip.

[0014] The beneficial effects of the present invention are:

[0015] 1. In the present invention, the sealing performance of the product is improved by designing multiple sealing lips and cooperating with the raised parts.

[0016] 2. In the present invention, by designing the first opening and the second opening, the fit between the product and the car is improved, and the sealing performance of the product is further improved.

[0017] 3. In the present invention, by adjusting the structure of the single-cell sealing strip base and its relative position to the second extension portion and the raised portion, folding can be avoided and rain leakage can be prevented.

[0018] 4. In the present invention, a rebound groove is provided at the connection between the third lip and the second extension portion, which further improves the sealing performance of the product. BRIEF DESCRIPTION OF THE DRAWINGS
