[0036] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a vehicle roof structure is provided.

[0037] Specifically, the vehicle roof structure includes: a front crossbeam assembly 1, a middle crossbeam assembly 2, and a rear crossbeam assembly 3. The front crossbeam assembly 1 extends along the width direction of the vehicle and is connected between the left and right doors 4. The middle crossbeam assembly 2 extends along the width direction of the vehicle and is connected between the left and right doors 4. The rear crossbeam assembly 3 extends along the width direction of the vehicle and is connected between the left and right doors 4. The middle crossbeam assembly 2 is located between the rear crossbeam assembly 3 and the front crossbeam assembly 1.

[0038] In the embodiments of this application, the front crossbeam assembly 1, the middle crossbeam assembly 2, and the rear crossbeam assembly 3 are all connected between the left and right side doors 4, with the middle crossbeam assembly 2 located between the front crossbeam assembly 1 and the rear crossbeam assembly 3. Each crossbeam assembly can distribute the forces generated during vehicle driving or collisions to ensure the rigidity of the entire vehicle. Furthermore, the installation position of each crossbeam assembly in the length direction of the vehicle can be adjusted according to assembly requirements to meet the design requirements of the panoramic sunroof and the panoramic windshield roof, thereby reducing the types of body-in-white. The aforementioned vehicle roof structure, while ensuring the rigidity of the entire vehicle, improves its versatility and reduces manufacturing costs by adjusting the installation position of each crossbeam assembly.

[0039] In one exemplary embodiment of this application, the front crossbeam assembly 1 is a hollow structure, and / or the middle crossbeam assembly 2 is a hollow structure, and / or the rear crossbeam assembly 3 is a hollow structure.

[0040] Designing one or more of the crossbeam assemblies as hollow structures reduces the weight of the crossbeam assembly, which is beneficial for lightweight vehicle design. Hollow structures can provide higher bending and torsional rigidity than solid structures through the design of their geometry and internal space.

[0041] As a preferred embodiment, the front crossbeam assembly 1, the middle crossbeam assembly 2, and the rear crossbeam assembly 3 are all hollow structures.

[0042] In one exemplary embodiment of this application, the front crossbeam assembly 1 includes a front roof outer panel 11 and a front roof inner panel 12. The front roof inner panel 12 is connected to the front roof outer panel 11, and a first cavity is formed between the front roof inner panel 12 and the front roof outer panel 11. The first cavity extends along the length direction of the front roof inner panel 12, wherein at least one of the front roof outer panel 11 and the front roof inner panel 12 is connected to the side wall of the door 4.

[0043] The inner front roof panel 12 and the outer front roof panel 11 are connected vertically to form a first cavity, which increases the moment of inertia of the front crossbeam assembly 1, thereby improving the structural rigidity of the front crossbeam assembly 1. The first cavity structure helps to reduce the weight of the front crossbeam assembly 1, which is beneficial to the lightweight design of the vehicle. The first cavity structure also helps to optimize the vibration characteristics of the vehicle body, reduce body resonance and noise, and improve the ride comfort of the vehicle.

[0044] Furthermore, the front crossbeam assembly 1 also includes a first connector 13, one end of which is detachably connected to the inner panel 12 of the front roof, and the other end of which is detachably connected to the side panel of the door 4.

[0045] The first connector 13 is detachably connected to the inner panel 12 of the front roof, so that different first connectors 13 can be replaced according to the structure of different doors 4 to adapt to different door structures, further improving the universality of the front crossbeam assembly 1. The detachable connection between the first connector 13 and the side panel of the door 4 does not require pre-reserved welding space compared with welding, and the disassembly and assembly are more convenient, which is conducive to the maintenance and replacement of the first connector 13 in the future.

[0046] like Figure 2 As shown, the inner front roof panel 12 and the outer front roof panel 11 are connected by welding. The first connector 13 is a groove-shaped structure adapted to the inner front roof panel 12. The first connector 13 is fastened to the outside of the inner front roof panel 12, and the inner wall of the first connector 13 is in contact with the outer wall of the inner front roof panel 12. The first connector 13 and the inner front roof panel 12 are connected by multiple bolts. The end of the first connector 13 near the door 4 is provided with a first flange, and the first flange is connected to the side panel of the door 4 by multiple bolts.

[0047] The outer wall of the front top cover 11 is provided with multiple glue-applying grooves 5. The multiple glue-applying grooves 5 are spaced apart along the length of the front top cover 11. The front top cover 11 is bonded to the glass through the glue-applying grooves 5.

[0048] In one exemplary embodiment of this application, the central crossbeam assembly 2 includes a central top cover outer panel 21 and a central top cover inner panel 22. The central top cover inner panel 22 is connected to the central top cover outer panel 21, and a second cavity is formed between the central top cover inner panel 22 and the central top cover outer panel 21. The second cavity extends along the length direction of the central top cover inner panel 22, wherein at least one of the central top cover inner panel 22 and the central top cover outer panel 21 is connected to the side wall of the door 4.

[0049] The inner panel 22 of the middle roof and the outer panel 21 of the middle roof are connected vertically to form a second cavity, which increases the moment of inertia of the cross section of the middle crossbeam assembly 2, thereby improving the structural stiffness of the middle crossbeam assembly 2. The setting of the second cavity structure helps to reduce the weight of the middle crossbeam assembly 2, which is conducive to the lightweight design of the vehicle. The setting of the second cavity structure helps to optimize the vibration characteristics of the vehicle body, reduce body resonance and noise, and improve the ride comfort of the vehicle.

[0050] Furthermore, the central crossbeam assembly 2 also includes a second connector 23, one end of which is detachably connected to the inner panel 22 of the central top cover, and the other end of which is detachably connected to the side panel of the door 4.

[0051] The second connector 23 is detachably connected to the inner panel 22 of the central top cover, so that different second connectors 23 can be replaced according to the structure of different doors 4 to adapt to different door structures, further improving the versatility of the central crossbeam assembly 2; the detachable connection between the second connector 23 and the side panel of the door 4 does not require pre-reserved welding space compared to welding, and is more convenient to disassemble and assemble, which is conducive to the maintenance and replacement of the second connector 23 in the future.

[0052] like Figure 3 As shown, the inner panel 22 and outer panel 21 of the central roof are connected by welding. The second connector 23 is a groove-shaped structure adapted to the inner panel 22 of the central roof. The second connector 23 is fastened to the outside of the inner panel 22 of the central roof, and the inner wall of the second connector 23 is in contact with the outer wall of the inner panel 22 of the central roof. The second connector 23 and the inner panel 22 of the central roof are connected by multiple bolts. The end of the second connector 23 near the door 4 is provided with a second flange, which is connected to the side panel of the door 4 by multiple bolts. The inner panel 22 of the central roof has a symmetrical structure and is provided with an anti-misassembly mark 24 to further identify the front and rear ends of the inner panel 22 of the central roof to avoid incorrect assembly of the inner panel 22 of the central roof.

[0053] Furthermore, the middle top cover outer plate 21 has a first step surface 211 and a second step surface 212, with a height difference between the first step surface 211 and the second step surface 212. The first step surface 211 is flush with part of the front crossbeam assembly 1, and the second step surface 212 is flush with part of the rear crossbeam assembly 3.

[0054] The stepped surface design ensures a smooth transition between the middle roof outer panel 21 and the front crossbeam assembly 1 and the rear crossbeam assembly 3, avoiding step differences, making the roof appearance more beautiful and the lines smooth, thus improving the overall visual effect and design of the vehicle.

[0055] like Figure 4As shown, the central roof outer panel 21 has a stepped structure, with a height difference between the first step surface 211 and the second step surface 212. The vertical height of the first step surface 211 is greater than that of the second step surface 212. The first step surface 211 is used for connection with the windshield glass, and the second step surface 212 is used for connection with the panoramic sunroof glass. The thickness of the windshield glass is less than that of the panoramic sunroof glass. Multiple adhesive grooves 5 are provided on the outer wall of the central roof outer panel 21, spaced apart along the length of the central roof outer panel 21. The central roof outer panel 21 is bonded to the glass through these adhesive grooves 5.

[0056] In one exemplary embodiment of this application, the rear crossbeam assembly 3 includes a rear roof outer panel 31 and a rear roof inner panel 32. The rear roof inner panel 32 is connected to the rear roof outer panel 31, and a third cavity is formed between the rear roof inner panel 32 and the rear roof outer panel 31. The third cavity extends along the length direction of the rear roof inner panel 32, wherein at least one of the rear roof outer panel 31 and the rear roof inner panel 32 is connected to the side panel of the door 4.

[0057] The rear roof inner panel 32 and the rear roof outer panel 31 are connected vertically to form a third cavity, which increases the moment of inertia of the rear crossbeam assembly 3, thereby improving the structural rigidity of the rear crossbeam assembly 3. The setting of the third cavity structure helps to reduce the weight of the rear crossbeam assembly 3, which is conducive to the lightweight design of the vehicle. The setting of the third cavity structure helps to optimize the vibration characteristics of the vehicle body, reduce body resonance and noise, and improve the ride comfort of the vehicle.

[0058] like Figure 5 As shown, the inner rear roof panel 32 and the outer rear roof panel 31 are connected by welding, and the outer rear roof panel 31 is welded to the side wall of the door 4. The outer wall of the outer rear roof panel 31 has multiple adhesive grooves 5, which are spaced apart along the length of the outer rear roof panel 31. The outer rear roof panel 31 is bonded to the glass through these adhesive grooves 5.

[0059] In one exemplary embodiment of this application, the vehicle roof structure further includes: a panoramic windshield, a sunroof, and a roof glass. The panoramic windshield is connected to a first end of the front crossbeam assembly 1, one end of the sunroof is connected to a second end of the front crossbeam assembly 1, the other end of the sunroof is connected to a first end of the middle crossbeam assembly 2, one end of the roof glass is connected to a second end of the middle crossbeam assembly 2, and the other end of the roof glass is connected to a rear crossbeam assembly 3.

[0060] It should be noted that when the front crossbeam assembly 1 is connected to the panoramic windshield, the front crossbeam assembly 1 moves to the upper area of ​​the 4B pillar of the door. When the front crossbeam assembly 1 is connected to the ordinary windshield, the front crossbeam assembly 1 is located between the 4A pillar and the 4B pillar of the door.
