Description

Technical Field

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

[0002] To meet users' needs for a wider view of the scenery while driving, the current roof designs of cars on the market are mainly fixed glass panoramic skylights and segmented, openable panoramic sunroofs. A panoramic skylight is different from a sunroof structure embedded in the roof structure. It refers to a structure that uses an entire piece of glass as the roof of the car, replacing the traditional car roof. Fixed panoramic skylights have advantages such as good light transmittance, a wide field of view, and a simple shape, but they also have disadvantages such as poor light and heat insulation and slow heat dissipation in the car. To solve this problem, the rear windshield of the glass is located on the rear side of the roof. The opening of the rear windshield can achieve ventilation and heat dissipation in the car, while also having the characteristics of a large light-transmitting area.

[0003] However, since both the rear windshield and the panoramic sunroof are glass components, they carry significant weight and are connected to the vehicle body frame, placing high demands on the frame's strength. Furthermore, because the rear windshield abuts the roof when closed and slides above it when open, a drive component is required on the frame to connect it to the rear windshield, further increasing the frame's strength and rigidity requirements. However, simply increasing the frame's material thickness to achieve these gains would result in excessive frame weight, compromising the vehicle's overall lightweighting. Utility Model Content

[0004] The purpose of the utility model is to provide a panoramic skylight structure and vehicle, aiming to solve the problems in the prior art that the body frame is not strong enough to provide effective support for the rear windshield and skylight glass, and increasing the thickness of the body frame easily causes the weight of the entire vehicle to be too large.

The rear crossbeam divides the side supports from front to rear into a roof installation area and a rear window installation area. The roof structure is connected to the roof installation area, and the rear windshield is connected to the rear window installation area. Both the roof structure and the rear windshield are mounted on the rear crossbeam. The rear crossbeam is provided with a first water flow trough in opposite directions along the left and right directions, and the first water flow trough corresponds to the bottom of the joint between the roof structure and the rear windshield.

Since the rear windshield needs to switch between an open state and a closed state during use, the vehicle body frame at the connection between the rear windshield and the roof structure needs to withstand a greater force to ensure the stability of the rear windshield during the opening and closing process. Therefore, the present invention provides a reinforcing beam at the bottom of the vehicle body frame, and the reinforcing beam corresponds to the connection between the roof structure and the rear windshield, thereby increasing the strength and stability of the vehicle body frame.

The terms "including," "having," and their variations used in the claims, specification, and drawings of this utility model are intended to mean "including but not limited to."

[0026] Please also refer to Figures 1 to 4 The panoramic sunroof structure and vehicle provided by the present invention are now described. The panoramic sunroof structure includes a roof structure 2, a rear window 1 located behind the roof structure 2, and a vehicle body frame 3 located below the roof structure 2 and the rear window 1. The roof structure 2 and the rear window 1 are sealed and butted together in the front-to-rear direction and are respectively connected to the vehicle body frame 3. The panoramic sunroof structure also includes a reinforcement beam 4 connected to the bottom of the vehicle body frame 3. The reinforcement beam 4 corresponds to the junction of the roof structure 2 and the rear window 1 in the vertical direction, and the reinforcement beam 4 has a reinforcement channel 402 along its extension path.

[0027] Compared to the prior art, the panoramic skylight structure provided by the present invention connects the roof structure 2 and rear window 1 separately to the vehicle body frame 3. When the rear window 1 is closed, the structure seals against the roof structure 2, ensuring a sealed seal across the vehicle and preventing external water and dust from entering the vehicle interior. Because the rear window 1 switches between open and closed positions during use, the vehicle body frame 3 at the junction of the rear window 1 and the roof structure 2 must withstand greater forces to ensure stability during the opening and closing of the rear window 1. Therefore, the present invention incorporates a reinforcement beam 4 at the bottom of the vehicle body frame 3, corresponding to the junction between the roof structure and the rear window 1, to enhance the strength and stability of the vehicle body frame 3. The reinforcement beam 4 has a reinforcement channel 402 along its extension, further enhancing its strength and rigidity compared to a flat-plate structure. Furthermore, the present invention eliminates the need to increase the thickness of the vehicle body frame 3 or the reinforcement beam 4, contributing to overall vehicle lightweighting.

[0028] In some embodiments, see Figure 2 The reinforcement beam 4 includes two reinforcement members 401 connected in the up-down direction. The reinforcement member 401 has a reinforcement groove. The two reinforcement grooves are connected to form a reinforcement channel 402.

[0029] In this embodiment, two reinforcement members 401 are joined vertically to form the reinforcement beam 4. Compared to a one-piece tubular structure, this allows for a larger reinforcement channel 402 to be formed. The reinforcement member 401 can be formed from a plate-like member using a stamping or bending process, simplifying the production process. Furthermore, since the reinforcement beam 4 is an arc-shaped member that bends forward or backward, using a one-piece tubular member would require a bending process, making the manufacturing process more complex.

[0030] Optionally, the reinforcement member 401 is a U-shaped member, and the open ends of two U-shaped members are butted together to form a tubular member with a smooth outer wall.

[0031] Optionally, the two reinforcement members 401 are welded or bonded.

[0032] In some embodiments, see Figure 2 The reinforcement 401 includes a reinforcement portion 4011 and connecting portions 4012 located on both sides of the reinforcement portion 4011 along the front-to-back direction. The reinforcement portion 4011 is a "U"-shaped structure. The connecting portion 4012 extends along the front-to-back direction and is connected to the open end of the reinforcement portion 4011. The connecting portion 4012 is connected to the corresponding connecting portion 4012 of another reinforcement 401, and the reinforcement groove is located in the reinforcement portion 4011.

[0033] Since the connecting portion 4012 extends in the front-to-back direction, the two corresponding connecting portions 4012 can be connected to increase the connection area, thereby improving the firmness and stability of the connection. The reinforcing portion 4011 is a "U" member. When the two reinforcing portions 4011 are connected, the reinforcing grooves of the "U"-shaped member jointly form the reinforcing channel 402.

[0034] Optionally, the two connecting parts 4012 are welded to increase the number of welding points and enhance the firmness of the connection.

[0035] In some embodiments, see Figure 2 The panoramic skylight structure also includes a reinforcement beam 5 located above the vehicle body frame 3 . The reinforcement beam 5 is connected to the bottom of the rear windshield 1 and has a reinforcement cavity 503 .

[0036] Since the rear windshield 1 is a glass component with limited strength and rigidity, attaching a reinforcement beam 5 to the bottom of the rear windshield 1 increases its strength. Furthermore, glass components are difficult to drill, which can easily cause cracking. However, the rear windshield 1 also needs to be connected to other body components. Therefore, the reinforcement beam 5 is bonded to the bottom of the rear windshield 1, connecting it to the body components. The reinforcement beam 5 has a reinforced cavity, which not only prevents interference with the rear windshield 1 during connection, but also improves its strength and deformation resistance.

[0037] Optionally, the reinforcement beam 5 is a tubular structure.

[0038] In some embodiments, see Figure 2 The reinforcement beam 5 includes a reinforcement portion 501 and connecting flanges 502 connected to opposite sides of the reinforcement portion 501 along the front-to-back direction. The reinforcement portion 501 has a reinforcement groove that is recessed downward. The connecting flange 502 is connected to the bottom of the rear window 1. The rear window 1 covers the opening of the reinforcement groove and forms a reinforcement cavity 503.

[0039] The reinforcement portion 501 and the connecting flange 502 form a U-shaped structure with flanges in the front-to-back direction. The opening of the U-shaped structure faces downward. After the connecting flange 502 is connected to the rear window 1, the rear window 1 covers the opening of the U-shaped structure to form a reinforcement cavity 503. The connecting flange 502 increases the contact area with the rear window 1, improving the connection strength. The U-shaped structure of the reinforcement portion 501 reduces weight compared to a tubular structure, contributing to the lightweighting of the entire vehicle.

[0040] In some embodiments, see Figure 4The vehicle body frame 3 includes two side supports 301 spaced apart in the left-right direction, a front crossbeam 302 connected to the front ends of the two side supports 301, and a rear crossbeam 303 located at the rear side of the front crossbeam 302 and connected to the two side supports 301. The rear crossbeam 303 divides the side supports 301 from front to back into a roof installation area and a rear window installation area. The roof structure 2 is connected to the roof installation area, and the rear windshield 1 is connected to the rear window installation area. The roof structure 2 and the rear windshield 1 are both mounted on the rear crossbeam 303. The rear crossbeam 303 has a first water flow trough 3031 opened in opposite directions in the left-right direction. The first water flow trough 3031 corresponds to the lower part of the joint between the roof structure 2 and the rear windshield 1.

[0041] The roof structure 2 and rear window 1 are both mounted on the rear crossbeam 303. Therefore, the joint between the roof structure 2 and rear window 1 corresponds to the rear crossbeam 303. If water temporarily accumulates at this joint, it could easily enter the rear crossbeam 303 and potentially infiltrate the cockpit. A water gutter is provided at the junction of the rear crossbeam 303 and the roof structure 2 and rear window 1 to drain any water that enters the rear crossbeam 303, ensuring a clean and tidy interior. Furthermore, the vehicle body frame 3 in this embodiment provides effective support for both the roof structure 2 and rear window 1, while also avoiding the added weight of the vehicle body frame 3 due to its complex structure.

[0042] Optionally, a first mounting groove is opened in the ceiling mounting area along the front-to-back direction for accommodating the front slide rail, and a second mounting groove is opened in the rear window mounting area along the front-to-back direction for accommodating the rear slide rail. The rear wind window 1 is respectively connected to the front slide rail and the rear slide rail to enable the rear wind window 1 to move above the ceiling after being raised.

[0043] In some embodiments, see Figures 3 and 4 The front cross beam 302 has a downwardly protruding reinforcement area, and the top of the reinforcement area forms a concave avoidance groove 3021, which forms a separation space with the roof structure 2 in the upper and lower directions.

[0044] The ceiling structure 2 is overlapped with the front cross beam 302, so the front cross beam 302 needs to provide support for the ceiling structure 2. A downward protruding reinforcement area is set on the front cross beam 302. On the one hand, it can increase the strength of the strong cross beam. On the other hand, the avoidance groove 3021 can form a separation space with the ceiling structure 2 in the upper and lower directions, avoiding the front cross beam 302 from being completely attached to the ceiling structure 2, thereby achieving the effect of buffering and shock absorption.

[0045] In some embodiments, see Figure 1The ceiling structure 2 includes a skylight glass 201, a side trim panel 202 located on the outside of the skylight glass 201, and a front trim panel 203 located on the front side of the skylight glass 201. The front trim panel 203 is correspondingly connected to the front cross beam 302. The front ends of the skylight glass 201 and the side trim panel 202 are connected to the front cross beam 302, and the rear ends are connected to the rear cross beam 303. The front cross beam 302 is provided with a second water flow trough 3022, and the second water flow trough 3022 is correspondingly arranged below the connection between the skylight glass 201 and the front trim panel 203.

[0046] The front fascia 203 and side fascia 202 are both non-glass components, while the skylight glass 201 is a glass component. Positioning the front fascia 203 and side fascia 202 on the front and outer sides of the skylight glass 201, respectively, effectively protects the outer edges of the skylight glass 201 from external forces. Furthermore, because glass components are less likely to bend and form flanges, sealing strips can be installed around the outer perimeter of the skylight glass 201 to achieve a sealed connection with the front fascia 203 and side fascia 202. The front fascia 203 and rear fascia are non-glass components, allowing for flanged edges for easier connection to the side panels.

[0047] Optionally, sealing strips are respectively provided around the peripheries of the front trim panel 203 , the side trim panels 202 , the skylight glass 201 and the rear windshield 1 .

[0048] In some embodiments, see Figure 3 The front trim panel 203 includes a trim panel body 2032 and a reinforcing flange 2031 circumferentially arranged at the outer edge of the trim panel body 2032 . The reinforcing flange 2031 and the trim panel body 2032 enclose a cavity structure with a bottom opening.

[0049] Compared with the flat plate structure, the solution in this embodiment has increased strength and rigidity, is less prone to deformation, and the reinforced flange 2031 abuts against the skylight glass 201 and the side trim panel 202 respectively, increasing the contact area and improving the sealing performance.

[0050] Optionally, the decorative plate body 2032 and the reinforcing flange 2031 are an integral component and can be prepared by a stamping process.

[0051] Based on the same inventive concept, the present invention further provides a vehicle comprising the above-mentioned panoramic skylight structure.

[0052] The vehicle provided by the present invention utilizes the aforementioned panoramic skylight structure, with the roof structure 2 and rear window 1 separately connected to the vehicle body frame 3. When the rear window 1 is closed, the roof structure 2 is sealed against the roof structure 2, ensuring the vehicle's sealing performance and preventing external water and dust from entering the vehicle interior. Because the rear window 1 needs to switch between open and closed states during use, the vehicle body frame 3 at the connection between the rear window 1 and the roof structure 2 must withstand greater forces to ensure the stability of the rear window 1 during opening and closing. Therefore, the present invention provides a reinforcement beam 4 at the bottom of the vehicle body frame 3, corresponding to the connection between the roof structure and the rear window 1, to increase the strength and stability of the vehicle body frame 3. The reinforcement beam 4 has a reinforcement channel 402 along its extension path, further enhancing the strength and rigidity of the reinforcement beam 4 compared to a flat plate structure. Furthermore, the present invention eliminates the need to increase the thickness of the vehicle body frame 3 or the reinforcement beam 4, facilitating overall vehicle lightweighting.

[0053] 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.
