Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle components, and more specifically, relates to a roof structure and a vehicle. Background Art

[0002] As living standards continue to improve, consumers are increasingly demanding more comfortable driving. Vehicle noise is the primary issue to be addressed. When a vehicle is driving, turbulence or leakage noise generated by airflow across the vehicle body is the primary cause of wind noise. When the airflow passes through the front windshield and flows toward the roof, its velocity increases, causing the airflow to separate. The roofs of existing vehicles are mostly formed by splicing parts together, rather than as a one-piece structure. If the sealing performance of the joints between the components is reduced, it is very easy for airflow to enter the vehicle along the gaps in the joints, causing increased noise inside the vehicle. Because the roof area is very close to the driver's head, passengers in the vehicle are more susceptible to wind noise.

[0003] Furthermore, the sealing performance of the roof not only affects the noise level inside the vehicle, but also the interior environment. Most cars often have water accumulating between the front fascia (plastic or tempered glass) and the roof. Prolonged waterlogging can cause the internal sealing strip to fail, allowing water to penetrate the rubber strip at the bottom of the sealing strip and flow into the roof, affecting the interior environment.

[0033] Please also refer to Figure 1 and Figure 5The roof structure and vehicle provided by the present invention are now described. The roof structure includes a front fascia 1, a roof 2 disposed on the rear side of the front fascia 1, and side fascias 3 disposed on either side of the roof 2 in the left-right direction. The side fascias 3 and the roof 2 are both connected to the rear side of the front fascia 1. The roof structure also includes a sealing structure, which includes a first sealing strip 4 and a second sealing strip 5. The first sealing strip 4 is connected to the front side of the roof 2 and abuts the front fascia 1 in the front-to-back direction. The second sealing strip 5 is connected to the front side of the side fascias 3 and abuts the front fascia 1 in the front-to-back direction.

[0034] Compared with the prior art, the roof structure provided by the present invention is provided with a first sealing strip 4 and a second sealing strip 5 on the front sides of the ceiling 2 and the side trim 3, respectively, for closing the gap between the ceiling 2 and the side trim 3, thereby improving the sealing effect. The improved sealing performance between the front trim 1, the side trim 3 and the ceiling 2 can not only prevent external airflow from entering the vehicle, reduce noise inside the vehicle, and improve the NVH performance of the entire vehicle, but also prevent external water from entering the vehicle, ensuring a clean and tidy interior environment. The roof structure in the present invention is formed by connecting the front trim 1, the ceiling 2 and the side trim 3, so that the volume of each component is reduced, making it easier to process and install.

[0035] Optionally, the roof structure further includes a third sealing strip provided on the rear side of the front trim panel 1 , the third sealing strip abutting against the first sealing strip 4 and the second sealing strip 5 .

[0036] Optionally, the third sealing strip has a non-hollow structure to avoid excessive deformation of the third sealing strip, which may reduce the elastic reset ability after long-term use and affect the sealing effect.

[0037] Specifically, the first sealing strip 4 and the second sealing strip 5 are both flexible components, such as rubber components or EVA components.

[0038] In some embodiments, see Figures 2 to 5 The front trim panel 1 includes a trim panel body 101 and a sealing flange 102 provided on the rear side of the trim panel body 101 . The sealing flange 102 is bent downward and abuts against the first sealing strip 4 and the second sealing strip 5 .

[0039] In this embodiment, a sealing flange 102 is provided on the rear side of the trim panel body 101 to increase the contact area with the first sealing strip 4 and the second sealing strip 5. On the one hand, it can reduce the pressure on the first sealing strip 4 and the second sealing strip 5, and reduce the probability of damage to the first sealing strip 4 and the second sealing strip 5 after being subjected to force; on the other hand, it can also improve the sealing performance and prevent external airflow or water flow from entering the vehicle.

[0040] Optionally, the decorative plate body 101 and the sealing flange 102 are an integral component and can be prepared by a bending process.

[0041] In some embodiments, see Figures 4 and 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 has a deformation cavity 404 along its own extension path. The first sealing body 401 abuts against the front trim panel 1; the first mounting body 402 is arranged on the rear side of the first sealing body 401 and is connected to the bottom of the ceiling 2.

[0042] The first sealing body 401 and the first mounting body 402 are connected to the front and bottom of the roof 2, respectively. This not only increases the contact area with the roof 2 and enhances the secure connection, but also limits the first sealing strip 4 in the vertical and front-to-back directions, eliminating the need for positioning during installation and making installation more convenient. Because the first sealing body 401 defines a deformation cavity 404, it deforms more significantly when in contact with the front fascia 1, ensuring a tight connection and improving sealing performance.

[0043] Optionally, the first sealing body 401 and the first mounting body 402 are respectively bonded to the ceiling 2 .

[0044] In some embodiments, see Figures 4 and 5 The first sealing strip 4 further includes a guide piece 403 connected to the lower portion of the first sealing body 401. The guide piece 403 is inclined toward the front side to guide the flow direction of the water.

[0045] In this embodiment, a guide plate 403 is further provided. Since the guide plate 403 is tilted toward the rear, the remaining water flow between the first sealing body 401 and the front trim panel 1 can be directed toward the front to prevent it from entering the vehicle.

[0046] In some embodiments, see Figures 2 to 3 The second sealing strip 5 includes a second sealing body 501 and a second mounting body 502. The second sealing body 501 is arranged on the front side of the side trim panel 3 and has an extrusion cavity 503 along its own extension path. The second sealing body 501 abuts against the front trim panel 1; the second mounting body 502 is arranged on the rear side of the second sealing body 501 and is connected to the bottom of the side trim panel 3.

[0047] The second sealing body 501 and the second mounting body 502 are respectively connected to the front and bottom of the side trim panel 3. This not only increases the contact area with the side trim panel 3 and improves the connection security, but also limits the second sealing strip 5 in the vertical and front-to-back directions, eliminating the need for positioning during installation and making installation more convenient. Because the second sealing body 501 defines a deformation cavity 404, it can deform more when it abuts the front trim panel 1, ensuring a tight connection and improving sealing performance.

[0048] Optionally, the second sealing body 501 and the second mounting body 502 are respectively bonded to the ceiling 2 .

[0049] In some embodiments, see Figures 2 to 3 The second mounting body 502 defines a sealed cavity along its own extension path, and the second sealing body 501 and the second mounting body 502 are both in contact with the vehicle body frame 6 in the up-down direction.

[0050] Because the second sealing body 501 is vertically positioned between the side trim panel 3 and the vehicle body frame 6, connected to the side trim panel 3 and abutting the vehicle body frame 6, the vehicle's sealing performance is further improved. Even if the seal between the second sealing body 501 and the front trim panel 1 fails, water and air cannot enter the vehicle through the gap between the side trim panel 3 and the vehicle body frame 6. The sealing cavity provided in the second sealing body 501 allows for greater deformation, allowing it to fit more closely to the vehicle body frame 6 and the side trim panel 3. Because the second mounting body 502 abuts not only the front trim panel 1 but also the top of the vehicle body frame 6, the sealing performance at the connection between the front trim panel 1 and the side trim panel 3 is further improved.

[0051] In some embodiments, see Figures 2 to 3 The second mounting body 502 includes a connecting portion 5021 and lips 5022 provided at the top and bottom of the connecting portion 5021 , and the lips 5022 abut against the vehicle body frame 6 .

[0052] The lip 5022 abuts against the vehicle body frame 6, which improves the sealing performance between the side trim panel 3 and the vehicle body frame 6 while reducing the resistance during installation. At the same time, the contact area between the lip 5022 and the vehicle body frame 6 and the side trim panel 3 is reduced, which also avoids the problem of deformation of the side trim panel 3 due to thermal expansion and contraction of the second mounting body 502 after long-term use.

[0053] Optionally, a sealed cavity is opened in the connecting portion 5021 .

[0054] Based on the same inventive concept, the present invention also provides a vehicle. Figures 1 to 5 , the vehicle includes the above-mentioned roof structure.

[0055] The vehicle provided by the present invention adopts the above-mentioned roof structure, and a first sealing strip 4 and a second sealing strip 5 are respectively provided on the front sides of the roof 2 and the side trim 3, which are used to close the gap between the roof 2 and the side trim 3, thereby improving the sealing effect. After the sealing performance between the front trim 1 and the side trim 3 and the roof 2 is improved, it can not only prevent external airflow from entering the vehicle, reduce the noise inside the vehicle, and improve the NVH performance of the entire vehicle, but also prevent external water from entering the vehicle, ensuring a clean and tidy environment inside the vehicle. The roof structure in the present invention is formed by connecting the front trim 1, the roof 2 and the side trim 3, so that the volume of each component is reduced, which is more convenient for processing and installation.

[0056] In some embodiments, see Figures 2 to 5The vehicle also includes a body frame 6, the front trim panel 1, the roof 2 and the side trim panels 3 are all connected to the top of the body frame 6, and the body frame 6 has a water flow channel 601 correspondingly arranged below the first sealing strip 4 and the second sealing strip 5. The water flow channel 601 is used to discharge the water accumulated between the front trim panel 1 and the roof 2 and the side trim panels 3.

[0057] When the sealing performance of the first sealing strip 4 and the second sealing strip 5 decreases, external water flows into the water channel 601 along the gap between the first sealing strip 4 and the second sealing strip 5 and the front trim panel 1, preventing water from entering the vehicle and ensuring a clean environment inside the vehicle.

[0058] Optionally, both ends of the water trough 601 are connected to the vehicle body drainage system.

[0059] In some embodiments, see Figure 5 A mounting block 201 is provided at the bottom of the front trim panel 1, the mounting block 201 abuts against the top of the body frame 6, and is provided with a first mounting hole. The body frame 6 is provided with a second mounting hole corresponding to the first mounting hole, and a locking member 7 is inserted into the first mounting hole and the second mounting hole.

[0060] Mounting block 201 abuts against vehicle body frame 6, limiting the position of front fascia 1. Locking member 7 is inserted through the first and second mounting holes to connect front fascia 1 to vehicle body frame 6. Because the first mounting hole is provided in the mounting hole, locking member 7 inserted into the first mounting hole increases the contact area with the mounting hole, thus improving the connection security compared to a solution in which the first mounting hole is provided in front fascia 1.

[0061] Optionally, the locking member 7 is a threaded member or a clamping member. When the locking member 7 is a threaded member, the first mounting hole is a threaded hole.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
