One of the medium and high-end cars has a sunroof structure on the top of the car. The sunroof can increase the sufficient ventilation effect and light intensity in the car. At the same time, the sunroof is also a symbol of the fashion and personality of the car. The wide field of view eliminates the feeling of depression in the cabin and increases the driving pleasure.

For example, the Chinese patent literature once disclosed a car sunroof installation structure [Chinese Patent No.: ZL200910191230.X; authorized announcement number: CN101695897A], including a roof cover, a sunroof reinforcement plate and a sunroof body, and the sunroof reinforcement plate is fixed on the roof At the skylight of the cover, projection welding nuts are arranged on the frame of the skylight reinforcement plate, and bolt holes are opened on the frame of the skylight body. The skylight reinforcement plate and the skylight body are connected by bolts through the projection welding nut and the bolt hole. The tail end of the sunroof body is connected with the roof cover, a positioning hole is opened on the frame on both sides of the sunroof reinforcement plate, and a positioning pin is arranged on the frame on both sides of the sunroof body, the skylight body is installed on the skylight reinforcement plate When the top is in the theoretical best position, the two positioning pins are respectively located in the two positioning holes and are in clearance fit with the positioning holes.

The installation structure of the above-mentioned automobile sunroof realizes the fixed connection to the sunroof body, but the installation structure will cause the sunroof reinforcement plate to loosen during the vibration generated by the driving of the automobile, thereby generating noise and reducing its service life.

Contents of the invention

The utility model provides a reinforcing structure of an automobile sunroof, which realizes firm fixing of a sunroof and a sunroof reinforcing plate through an edge-wrapping structure.

The purpose of the utility model can be achieved through the following technical proposals: a reinforced structure of a car sunroof, which is arranged on the roof of the car on which the sunroof can be installed. The sheet-shaped sunroof reinforcement plate is characterized in that the side edge corresponding to the rear end of the sunroof on the car roof has a downward wrapping edge, and the front side of the rear sunroof reinforcement plate located at the rear side of the sunroof is clipped to the Inside the hemming.

The reinforced structure of the car sunroof wraps one side of the sunroof reinforcement plate and closely abuts it to form the side to be clamped and fixed, so that the whole of the sunroof reinforcement plate is firmly connected with the roof cover of the car, preventing the The loosening of the sunroof reinforcement reduces noise and prolongs its service life.

In the above-mentioned reinforcing structure of the car sunroof, the said hemming includes a vertical connection part connected with the body of the car roof and a clamping part for pressing the rear sunroof reinforcement plate on the body of the car roof , the transition between the vertical connecting portion and the clamping portion is rounded. The rounded corner of the vertical connection part transitions to the clamping part which is parallel to the sunroof reinforcement plate and closely adheres to it to form an inner cavity capable of containing, which enables the side edge of the skylight reinforcement plate to be firmly embedded in it to form a clamping connection.

In the above-mentioned reinforced structure of the automobile sunroof, the height of the inner cavity of the wrapping is 6 mm to 8 mm. According to the empirical value, the height within this range can be firmly clamped to the skylight reinforcement plate and bear the force support.

In the above-mentioned reinforcing structure of the automobile sunroof, the front side of the rear sunroof reinforcing plate has a downward flange, and the flange is arranged in the wrapping of the car roof and abuts against the vertical connection portion of the wrapping. The abutment between the flange and the vertical connecting portion increases the contact area, so that the skylight reinforcing plate is in a stable position.

In the above-mentioned reinforcing structure for the sunroof of an automobile, the lower end of the flange is tangent to the rounded corner of the flange. The edge of the flanging produces an upward supporting force under the action of the tangential fillet, so that the sunroof reinforcement plate can be more stably fixed on the roof of the car.

In the above-mentioned reinforced structure of the automobile sunroof, the rear part of the rear skylight reinforcing plate is connected to the automobile roof by bonding.

In the above-mentioned reinforced structure for the sunroof of an automobile, the rear sunroof reinforcement plate is bonded to the roof of the automobile through shock-absorbing glue. Bonding the top side of the sunroof reinforcement plate to the roof of the car not only improves the reliability of fixing, but also reduces the noise generated by vibration.

In the above-mentioned reinforcing structure for the sunroof of an automobile, the rear sunroof reinforcing plate has several longitudinally arranged grooves. The groove is beneficial for glue coating and bonding of the sunroof reinforcement plate and the roof cover of the car, and at the same time improves the strength of the sunroof reinforcement plate.

Compared with the prior art, the hemming provided by the reinforced structure of the car sunroof greatly enhances the stability of the connection between the sunroof reinforcement plate and the car roof, prevents the vibration generated by the vehicle from causing the sunroof reinforcement plate to loosen, and reduces noise. Extended service life.

Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Figure 1 and Figure 2, the reinforcing structure of the car sunroof is arranged on the car roof 1 that can be installed with the sunroof, and the inside of the periphery of the car roof 1 for connecting the sunroof is respectively provided with sheet-shaped sunroof reinforcement plates 2. On the side edge of the car roof 1 corresponding to the rear end of the sunroof, there is an edge 1a capable of receiving and clamping the edge of the side sunroof reinforcement plate 2 .

The hemming 1a includes a vertical connection part 1a1 connected to the body of the car roof 1, and the end of the vertical connection part 1a1 is rounded, transitioned upwards and curved to connect with the rear sunroof reinforcement plate 2 to form a parallel and sticking snap connection Section 1a2. The front side edge of the rear sunroof reinforcement plate 2 located at the rear side of the sunroof extends into the wrapping 1a, which penetrates through the gap between the car roof 1 and the clamping part 1a2 and forms a close-fitting clamping connection with the two. The front edge of the skylight reinforcing plate 2 is bent vertically downward to form a flange 2a, so that the flange 2a is arranged in the cavity of the wrapping 1a. The height of the inner cavity of the wrapping 1a is 6 mm to 8 mm. According to empirical values, the height within this range can be firmly clamped to the rear sunroof reinforcement plate 2 and bear the force support. In this embodiment, 7.5 mm is used. The abutment of the flange 2a and the vertical connection portion 1a1 of the flange 1a increases the contact area, and the edge of its lower end is tangent to the fillet of the flange 1a, so that the fillet produces an upward direction on the flange 2a. The supporting force enables the rear sunroof reinforcement plate 2 to be more stably fixed on the car roof 1.

There are several longitudinally arranged grooves 2b on the rear sunroof reinforcement plate 2, which improve the strength of the rear sunroof reinforcement plate 2, and are located between the grooves 2b on the rear top side of the rear sunroof reinforcement plate 2 and the car roof 1 Apply shock-absorbing glue for bonding, so as to improve the reliability of fixing and reduce the noise generated by vibration.

The skylight is located below the skylight reinforcing plate 2 and is fixedly connected with the skylight reinforcing plate 2. Its overall structure is compact and stable, which prevents loosening, reduces noise, and prolongs its service life.
