Description

Technical Field

[0001] The present invention relates to the technical field of automobile sunroofs, and in particular to a ventilated automobile sunroof assembly. Background Art

[0002] Car roofs are categorized into fixed glass windows and panoramic sunroofs. Fixed glass windows are merely transparent, allowing for more sunlight, but they cannot be opened for ventilation. Panoramic sunroofs, on the other hand, allow drivers to enjoy the pleasure of driving by opening the glass while the vehicle is in motion, for example, improving ventilation and allowing for more sunlight. However, panoramic sunroofs typically include front and rear glass. The front glass is slidably mounted in front of the sunroof opening, while the rear glass is fixedly mounted in the rear. However, these panoramic sunroofs require a relatively complex sliding structure to achieve movement of the front glass, and a relatively complex sealing structure to ensure overall sealing of the panoramic sunroof. Some panoramic sunroofs have both front and rear glass that can be opened. For example, CN209552910 U discloses a dual-glass, double-opening panoramic sunroof for cars that allows both the front and rear glass to tilt and open simultaneously, but this structure is also relatively complex.

[0003] Therefore, a car sunroof assembly with a simple structure and easy ventilation is needed. Summary of the Invention

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0043] like Figure 1 As shown, the present invention provides a vehicle sunroof assembly, which includes:

[0044] A fixing mechanism includes an outer frame 4, a front glass 5, and a rear glass 3. The outer frame 4 sequentially forms a front window, a middle window, and a rear window. The front glass 5 is fixed in the front window, and the rear glass 3 is fixed in the rear window.

[0045] The opening mechanism is placed at the middle window. Figure 2 and Figure 3 、 Figure 4 As shown, the opening mechanism includes a cover plate 1 and a driving assembly 2. The size of the cover plate 1 is adapted to the middle window. The driving assembly 2 includes a connecting rod 21 and a rotating assembly. The connecting rod 21 is fixedly connected to the cover plate 1, and one end of the connecting rod 21 is slidably connected to the outer frame 4. The other end of the connecting rod 21 is connected to the rotating assembly. The rotation of the rotating assembly drives the cover plate 1 to rotate, thereby sealing or opening the middle window.

[0046] The outer frame 4 is provided with an extension portion 41 extending to the bottom of the cover plate 1 around the middle window. Figure 2 As shown, a sealing member 42 is provided on the extension portion 41 for contacting the cover plate 1 .

[0047] The automobile sunroof assembly of the present invention protects the fixed front glass 5 and rear glass 3, and is provided with an opening mechanism between the front and rear glasses. The cover plate 1 can be driven to rotate and open by a driving component to achieve ventilation. The driving component drives the cover plate 1 to rotate without the need for a sliding mechanism, thereby simplifying the overall structure of the sunroof. Moreover, through the provision of the extension portion 41 and the sealing member 42, the cover plate 1 and the outer frame 4 are sealed, thereby improving the sealing performance of the automobile sunroof assembly.

[0048] To facilitate drainage, see Figure 2As shown, in this embodiment, there are gaps between the cover plate 1 and the front window 5, and between the cover plate 1 and the rear window 3, and there are drainage grooves 6 on the extensions between the cover plate 1 and the front window 5, and the extensions 41 between the cover plate 1 and the rear window 3. The drainage grooves guide rainwater to the drainage area where the car sunroof assembly is connected to the car body, achieving centralized drainage. In addition, the provision of the drainage grooves 6 also prevents water from accumulating at the junction of the opening mechanism and the outer frame, which would cause the accumulated water to enter the car during the opening process. More preferably, in the vehicle width direction, this embodiment can be seen Figure 3 As shown, a drain port 61 communicating with the drain groove is provided between the cover plate 1 and the outer frame 4 , so that water collected in the drain groove can be discharged from the drain port 61 .

[0049] In order to improve the sealing performance of the automobile sunroof assembly, the sealing member 42 in this embodiment can be connected by snapping (see Figure 2 The seal 42 is fixed to the extension 41 by means of a sealant (as shown) or adhesive. The seal 42 can be a sealing bubble, a sealing strip with a closed cross section, or a sealing strip with an open cross section. The seal 42 has a certain degree of elasticity and, when the cover 1 is closed, contacts the bottom of the cover 1, achieving a tight fit and seal.

[0050] In this embodiment, the cover plate 1 can be made of glass or plastic, and its shape and size are compatible with the middle window formed in the outer frame. It only needs to form the above-mentioned gap to facilitate the collection of rainwater into the above-mentioned drainage groove 6. In this embodiment, the above-mentioned drive assembly is divided into two groups, respectively connected to the two ends of the cover plate 1. That is, in the left and right directions of the vehicle body, one drive assembly is provided at each end of the cover plate 1. The rotation of the cover plate 1 is achieved through the synchronous movement of the two drive assemblies. The two sets of drive assemblies improve the stability of the rotation of the cover plate 1.

[0051] In order to limit the vertical movement of the cover plate 1 within a certain range during the rotation process, see Figure 5 and Figure 6 As shown, in this embodiment, a mounting base with a sliding groove 43 is fixed to the bottom surface of the outer frame 4. One end of the connecting rod 21 is located in the sliding groove 43. When the rotating assembly rotates and drives the connecting rod 21, the sliding groove 43 restricts the sliding movement of the connecting rod 21 therein, thereby limiting the vertical swing range of the connecting rod 21. The sliding connection between the connecting rod 21 and the outer frame 4 is not limited to this. Other sliding fitting structures can also be used. For example, by providing a sliding groove on the connecting rod and a protrusion on the outer frame, so that the protrusion is located in the sliding groove, thereby achieving sliding fit between the connecting rod 21 and the outer frame 4. In this embodiment, the connecting rod 21 and the cover plate 1 can be fixed by snapping or bolting, or other fixing structures can also be used.

[0052] See Figures 4 and 5As shown, the rotating assembly in this embodiment includes a mounting shell 23, a driving motor (not shown) placed in the mounting shell 23, and a cam 24 connected to the driving motor. The other end of the connecting rod 21 is connected to the cam 24 via a crank 22; the mounting shell 23 is fixed to the outer frame 4. In this embodiment, the cam mechanism (i.e., the driving motor, cam, and crank) is used to achieve the swing of the connecting rod 21, thereby driving the rotation of the cover 1. To ensure that the cover 1 remains stationary after opening, an electromagnetic pin 25 is provided in the mounting shell 23 in this embodiment, and a pin hole is provided on the cam 24 to cooperate with the electromagnetic pin 25. Figure 5 As shown, when the cover is opened, the electromagnetic pin 25 is driven to move and inserted into the pin hole of the cam 24 to lock the cam. In addition, through the cooperation between the connecting rod 21 and the slide groove 43, the two ends of the connecting rod are positioned and immobilized, thereby further ensuring that the cover 1 does not move, so that the opening mechanism can be applied to the high-speed movement state of the car and will not be closed due to external forces such as vibration.

[0053] In order to improve the stability of opening and closing, a limiting protrusion 26 for limiting the rotation of the cam is provided on the mounting shell 23 in this embodiment. In this embodiment, the cam 24 is notched, and two limiting protrusions 26 are provided at the corresponding notches of the mounting shell 23, one of which is an upper limiting protrusion for limiting the cam during the opening process, and the other is a lower limiting protrusion for limiting the cam during the closing process. Figure 5 As shown, a stopper 27 is provided on the mounting shell 23 to stop the crank 22 from rotating, which further limits the opening range of the cover 1. The stopper 27 can make the crank 22 vertical, further maintaining the cover 1 motionless after opening.

[0054] Therefore, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
