Description

Roof structure and vehicle

Technical Field

The utility model belongs to the technical field of vehicle parts, and particularly relates to a roof structure and a vehicle.

Background

With the continuous improvement of living standard, consumers have increasingly improved requirements on automobile driving comfort, and automobile noise is a primary problem of automobile driving comfort. When the vehicle runs, turbulent flow or leakage noise generated by the air flow passing through the vehicle body is a main cause of wind noise, wherein when the air flow flows to the top cover through the front windshield, the speed is increased, and the air flow is separated. Most of the ceilings of the existing vehicles are formed by split splicing and are not of an integral structure, if the sealing performance of the joints between the components is reduced, wind current is very easy to enter the vehicle along the gaps of the joints, and the noise in the vehicle is increased. Because the roof area is very close to the head of the driver, the problem of wind noise is more easily perceived by passengers in the vehicle.

In addition, the sealing effect of the roof is not only related to the magnitude of noise in the vehicle but also related to the environmental problem inside the vehicle. Most front decorative plates (plastic decorative plates or toughened glass panels) of automobile installation and a ceiling are prone to water accumulation, if the front decorative plates are soaked by the water accumulation for a long time, the inside sealing strips are invalid, water can permeate the adhesive tapes at the bottoms of the sealing strips and flow into the ceiling, and the environment in the automobile is affected.

Compared with the prior art, the roof structure provided by the utility model has the advantages that the first sealing strip 4 and the second sealing strip 5 are respectively arranged on the front sides of the ceiling 2 and the side decorative plates 3 and are used for sealing gaps between the roof 2 and the side decorative plates, so that the sealing effect is improved. After the sealing performance between the front decorative plate 1, the side decorative plate 3 and the ceiling 2 is improved, external air flow can be prevented from entering the vehicle, noise in the vehicle is reduced, NVH performance of the whole vehicle is improved, external water flow can be prevented from entering the vehicle, and the internal environment of the vehicle is guaranteed to be tidy. The roof structure is formed by connecting the front decorative plate 1, the ceiling 2 and the side decorative plates 3, so that the volume of each part is reduced, and the processing and the installation are more convenient.

Optionally, the roof structure further includes a third sealing strip disposed at the rear side of the front trim panel 1, and the third sealing strip is abutted to the first sealing strip 4 and the second sealing strip 5.

Optionally, the third sealing strip is of a non-hollow structure, so that the problem that the elastic resetting capability is reduced after long-term use and the sealing effect is affected due to overlarge deformation of the third sealing strip is avoided.

Specifically, the first sealing tape 4 and the second sealing tape 5 are each a flexible member, such as a rubber member or an EVA member.

In some embodiments, referring to fig. 2 to 5, the front trim panel 1 includes a trim panel body 101 and a sealing flange 102 disposed on a rear side of the trim panel body 101, where the sealing flange 102 is bent downward and abuts against the first sealing strip 4 and the second sealing strip 5.

In this embodiment, the sealing flange 102 is disposed at the rear side of the plaque body 101, so as to increase the contact area between the plaque body 101 and the first sealing strip 4 and the second sealing strip 5, on one hand, reduce the pressure intensity of the first sealing strip 4 and the second sealing strip 5, reduce the damage probability of the first sealing strip 4 and the second sealing strip 5 after being stressed, and on the other hand, improve the sealing performance, and avoid external air flow or water flow from entering the vehicle.

Alternatively, the trim body 101 and the sealing flange 102 are an integral component, which may be manufactured by a bending process.

In some embodiments, referring to fig. 4 to 5, the first sealing strip 4 includes a first sealing body 401 and a first mounting body 402, the first sealing body 401 is connected to the front side of the ceiling 2, and a deformation cavity 404 is formed along its own extending path, the first sealing body 401 abuts against the front trim 1, and the first mounting body 402 is disposed on the rear side of the first sealing body 401 and is connected to the bottom of the ceiling 2.

The second sealing body 501 and the second installation body 502 are respectively connected to the front side and the bottom of the side decoration plate 3, so that the contact area with the side decoration plate 3 is increased, the connection firmness is improved, the second sealing strip 5 is limited in the up-down direction and the front-back direction, positioning is not needed during installation, and the installation is more convenient. Since the second sealing body 501 is provided with the deformation cavity 404, the second sealing body 501 has larger deformation when being abutted against the front decorative plate 1, thereby ensuring tight connection and improving sealing performance.

Alternatively, the second sealing body 501 and the second mounting body 502 are adhered to the ceiling 2, respectively.

In some embodiments, referring to fig. 2 to 3, the second mounting body 502 is provided with a sealing cavity along its own extending path, and the second sealing body 501 and the second mounting body 502 are abutted against the vehicle body frame 6 along the up-down direction.

Since the second sealing body 501 is located between the side trim 3 and the vehicle body frame 6 in the up-down direction and is connected to the side trim 3 and abuts against the vehicle body frame 6, the sealing performance of the vehicle is further improved, and even after the sealing between the second sealing body 501 and the front trim 1 fails, water flow and air flow cannot enter the vehicle through the gap between the side trim 3 and the vehicle body frame 6. The second sealing body 501 is provided with a sealing cavity, so that the second sealing body 501 has larger deformation and can be more closely attached to the vehicle body frame 6 and the side decorative plate 3. The second mounting body 502 is not only abutted against the front trim 1 but also against the top of the body frame 6, so that the sealing performance of the joint between the front trim 1 and the side trim 3 is further improved.

In some embodiments, referring to fig. 2 to 3, the second mounting body 502 includes a connection portion 5021 and lips 5022 provided at the top and bottom of the connection portion 5021, the lips 5022 abutting against the vehicle body frame 6.

The lip 5022 is abutted to the vehicle body frame 6, so that the sealing performance between the side decorative plate 3 and the vehicle body frame 6 is improved, the resistance during installation is reduced, meanwhile, the contact area between the lip 5022 and the vehicle body frame 6 as well as the side decorative plate 3 is reduced, and the problem that the side decorative plate 3 is deformed due to expansion and contraction of the second installation body 502 after long-term use is avoided.

Optionally, the sealing cavity is formed in the connection portion 5021.

Based on the same inventive concept, the utility model also provides a vehicle. Referring to fig. 1 to 5, a vehicle includes the roof structure described above.

The vehicle provided by the utility model adopts the roof structure, and the front sides of the roof 2 and the side decorative plates 3 are respectively provided with the first sealing strip 4 and the second sealing strip 5, so that the gap between the vehicle and the roof 2 is closed, and the sealing effect is improved. After the sealing performance between the front decorative plate 1, the side decorative plate 3 and the ceiling 2 is improved, external air flow can be prevented from entering the vehicle, noise in the vehicle is reduced, NVH performance of the whole vehicle is improved, external water flow can be prevented from entering the vehicle, and the internal environment of the vehicle is guaranteed to be tidy. The roof structure is formed by connecting the front decorative plate 1, the ceiling 2 and the side decorative plates 3, so that the volume of each part is reduced, and the processing and the installation are more convenient.
