BACKGROUND OF THE DISCLOSURE

Technical Field

The present disclosure relates to a field of vehicles and in particular, to an anti-lift sunroof structure for automobiles.

Description of Related Art

In recent years, sunroofs have been widely used in various vehicles to meet the needs of users. Generally, there are two types of sunroofs: a fixed type and a movable type. Regardless of whether it is a fixed-type sunroof or a movable-type sunroof. In order to avoid entry of rain or moisture into the inside of a vehicle, rubber strips are disposed on an outer periphery of a window frame where a glass panel is mounted, so that the rubber strips can achieve sealing between the window frame and a vehicle metal part through elastic deformation of the rubber strips.

However, when the vehicle is running at high speed, a pressure difference between the inside and the outside of the vehicle causes a suction force to lift the movable-type sunroof toward the outside of the vehicle. Especially, when the speed of the vehicle reaches more than 200 kilometers per hour, a distance of positional shifting of the movable-type sunroof increases, which causes the rubber strips to be separated from the vehicle metal part, thus affecting a sealing effect of the rubber strips. Even worse, it may even cause the movable-type sunroof to be detached or fly away.

In light of the above, the inventor of the present disclosure has devoted himself to doing research and studying scientific principles so as to solve the above problem of related-art techniques.

DETAILED DESCRIPTION

The technical content of the present disclosure is described in detail below with reference to accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present disclosure.

The present disclosure provides an anti-lift sunroof structure which may be opened and closed corresponding to an opening A1 of a vehicle roof. Referring to FIGS. 1 to 4, the anti-lift sunroof structure mainly includes a glass panel 10, a window frame 20, a sealing strip 30, and a support element 40. It should be noted that the vehicle roof in the present embodiment includes a reinforcement frame A and a sheet metal portion B. The sheet metal portion B covers a top and sides of the reinforcement frame A to increase structural strength through the reinforcement frame A. The opening A1 is defined by the reinforcement frame A and the sheet metal portion B, and is provided for placing the anti-lift sunroof structure. The present disclosure is not limited to the above-mentioned. For example, the vehicle roof may only include the sheet metal portion B.

In the present embodiment, the glass panel 10 is substantially of a rectangular shape, and the four corners of the glass panel 10 are provided with rounded corners to avoid cracks due to stress concentration. The present disclosure is not limited in this regard, and designers may adjust a shape of the glass panel 10 according to requirements.

The window frame 20 matches the shape of the glass panel 10 and surrounds an outer periphery and a bottom of the glass panel 10. Specifically, the window frame 20 includes a front frame bar 21, two side frame bars 22, and a rear frame bar 23. Two ends of each side frame 22 are respectively connected to the front frame bar 21 and the rear frame bar 23. The front frame bar 21, the rear frame bar 23, and the side frame bars 22 form a mounting groove 24 for installation of the glass panel 10. The glass panel 10 may be mounted to the mounting groove 24 of the window frame 20 through bonding (adhesion), press-fitting, or buckling with fasteners, etc. The present disclosure is not limited to a particular assembly method. Any assembly method may be adopted as long as the glass panel 10 is fixed to the mounting groove 24. In the present embodiment, the window frame 20 is integrally formed (or formed in one piece) by injection molding of PU (polyurethane), but the present disclosure is not limited in this regard. The window frame 20 may also be integrally formed (or formed in one piece) by injection molding of other plastic materials.

The sealing strip 30 is disposed on an outer periphery of the window frame 20 to abut against an inner edge of the opening A1 of the sheet metal portion B to form a seal when the sunroof structure closes the opening A1 of the sheet metal portion B. The sealing strip 30 may be fixed to the window frame 20 by bonding (adhesion) or engagement. The drawing of the present embodiment shows fixation by means of engagement, but the present disclosure is not limited to the above-mentioned method. Specifically, the outer periphery of the window frame 20 in the present embodiment is provided with an engagement groove 25, and a covering portion 26 is extended from the outer periphery of the window frame 20. The sealing strip 30 includes an abutting portion 31 and a fastening strip 32 extended from the abutting portion 31. The covering portion 26 is located on a top of the window frame 20 and extended away from the mounting groove 24. The engagement groove 25 is located at a bottom of the window frame 20 with respect to the covering portion 26. A cross-section of the fastening strip 32 is roughly hook-shaped to be engaged with the engagement groove 25, so that the abutting portion 31 tightly abuts against the window frame 20 to achieve sealing, and the covering portion 26 abuts against and covers at least a portion of the abutting portion 31, so as to effectively ensure the sealing between the sealing strip 30 and the window frame 20.

The support element 40 is disposed corresponding to the front frame bar 21. A stop plate 41 is extended from the support element 40 in a direction away from the rear frame bar 23. The stop plate 41 protrudes from the front frame bar 21 and the sealing strip 30. Specifically, the support element 40 is provided with a plurality of coupling holes 42, and the window frame 20 is provided with a plurality of coupling blocks 27. Each coupling block 27 is secured in one of the coupling holes 42, so as to fix the support element 40 to the window frame 20. Please refer to FIG. 4, when the anti-lift sunroof structure of the present disclosure closes the opening A1 of the sheet metal portion B, the stop plate 41 is located under the sheet metal portion B of the vehicle roof and has a distance d from the sheet metal portion B. Accordingly, the stop plate 41 may stop the window frame 20 from lifting upward. In this way, when the sunroof structure is sucked upward due to a pressure difference between the inside and the outside of a vehicle as a result of the high-speed running of the vehicle, the stop plate 41 of the sunroof structure abuts against the reinforcement frame A, so the window frame 20 is only sucked to move the aforementioned distance d, so that the sealing strip 30 may still keep abutting against the inner edge of the opening A1, thereby effectively maintaining the sealing, as shown in FIG. 5.

In some embodiments, please refer to FIG. 6. FIG. 6 is another embodiment of the present disclosure. This embodiment is mainly different in that there is a wrapping portion 211 extended from the front frame bar 21, and the wrapping portion 211 wraps the stop plate 41. Specifically, the wrapping portion 211 in the present embodiment is injection molded together with the window frame 20 to cover the stop plate 41. The present disclosure is not limited in this regard. Such a configuration may prevent the stop plate 41 from directly contacting the sheet metal portion B of the vehicle roof. The present embodiment uses the wrapping portion 211 (PU) with low hardness to touch the sheet metal portion B (metal) of the vehicle roof, thus reducing noises generated from contacting the sheet metal portion B of the vehicle roof and may provide a buffer to reduce an impact force during contact. At the same time, the stop plate 41 wrapped inside may provide desirable structural strength for the overall structure.

In detail, the anti-lift sunroof structure of the present disclosure further includes additional support elements 40, and the additional support elements are respectively arranged corresponding to the rear frame bar 23 and the side frame bars 22, so as to strengthen the structural strength of the window frame 20. The window frame 20 further includes a plurality of connection plates 28, and the connection plates 28 are respectively arranged at junctions of the front frame bar 21 and the side frame bars 22 and arranged at junctions of the rear frame bar 23 and the side frame bars 22. The connection plates 28 collectively support the glass panel 10. Each connection plate 28 is provided with two coupling blocks 27, and a coupling hole 42 is defined at each of two ends of each support element 40. Each coupling block 27 is fixed in one of the coupling holes 42, thereby fixing each support element 40 to the window frame 20. A fixing method for the support element 40 and the window frame 20 is not limited in this regard. For example, the window frame 20 may also directly cover each support element 40 during injection molding.

Certainly, the present disclosure also can have other multiple embodiments. Without departing from the spirit and essence of the present disclosure, various changes and modifications can be made by those skilled in the art according to the present disclosure. Such changes and modifications should be deemed to belong to the protection scope of the present disclosure.
