[0001] The present application relates to the technical field of vehicles, and in particular, to a vehicle roof and a vehicle. Background Art

[0002] In recent years, with the continuous deepening of the pursuit of lightweight design in the automotive industry, the outer covering parts of vehicles have gradually developed towards being thinner and lighter. Although this design helps to improve fuel efficiency, reduce the overall vehicle weight, and conform to the global trend of energy conservation and emission reduction, it also brings a series of technical challenges. Especially for the vehicle roof, a key component, due to its unique styling requirements, it often has a relatively small bi-curvature. This design meets the streamlined appearance of the vehicle aesthetically, but there are problems such as insufficient drawing of stamping parts during manufacturing, resulting in a significant decrease in the stiffness of the roof. At the same time, due to lightweight requirements, the thickness of the roof has been greatly reduced, further exacerbating the problem of poor roof stiffness, leading to low dent resistance of the roof and easy occurrence of vibration and noise, seriously affecting the safety performance of the entire vehicle and the NVH (Noise, Vibration, Harshness) performance.

[0039] The following refers to Figures 1 - 4Describe the roof cover 100 and the vehicle 200 according to the embodiments of the present application.

[0040] As Figure 1 and Figure 2 shown, the roof cover 100 according to the embodiment of the first aspect of the present application, the roof cover 100 includes: a body 1 and a connecting beam 3.

[0041] Wherein, the body 1 is provided with a plurality of cross beams 2 spaced along the vehicle body length direction; the connecting beam 3 is connected to the body 1, straddles a plurality of cross beams 2, and is located on the width center line of the body 1.

[0042] Specifically, the body 1 is the main structure of the roof cover 100 for covering and protecting the top of the vehicle body. A plurality of cross beams 2 are arranged on the body 1, and the plurality of cross beams 2 are spaced along the vehicle body length direction, and each cross beam 2 extends in the vehicle body width direction. The plurality of cross beams 2 can strengthen the lateral support of the roof cover 100 and optimize the force transmission path and force dispersion performance of the roof cover 100, so that when the roof cover 100 is subjected to an impact force from the side, the stress can be more evenly dispersed, thereby reducing the risk of local depression; the connecting beam 3 straddles a plurality of cross beams 2 and is located on the width center line of the body 1. It can be understood that the connecting beam 3 straddles the midpoint position of the cross beam 2 in the extending direction and connects the plurality of cross beams 2. The connecting beam 3 can extend in the vehicle body length direction. The connecting beam 3 can strengthen the longitudinal support of the roof cover 100, while the cross beam 2 extends in the vehicle body width direction, so that the cross beam 2 and the connecting beam 3 cross to form a grid-like support structure, which can significantly improve the overall stiffness and anti-dent performance of the roof cover 100. Among them, the materials of the cross beam 2 and the connecting beam 3 can be selected from high-strength steel or aluminum alloy and other lightweight and high-strength materials to reduce the weight while ensuring the strength.

[0043] For the roof cover 100 according to the present application, by arranging the connecting beam 3 to straddle a plurality of cross beams 2, the roof cover 100 can effectively resist deformation and depression when subjected to external forces, effectively improve the anti-deformation ability, significantly enhance the overall structural strength and stiffness of the roof cover 100. Thus, on the basis of ensuring that the roof cover 100 meets the requirements of anti-dent and anti-bending and torsion resistance, more possibilities can be provided for the roof cover 100 to tend to small double curvature and lightweight design, so that the roof cover 100 can take into account good anti-dent performance and thin and light styling requirements, and further optimize the vehicle safety performance and NVH performance, and improve the user experience.

[0044] As Figures 1 - 3 shown, according to some embodiments of the present application, the connecting beam 3 includes a plurality of sub-beam bodies, and both ends of each sub-beam body are connected to the adjacent cross beam 2.

[0045] Specifically, the connecting beam 3 is composed of multiple sub-beam bodies. Each sub-beam body extends in the longitudinal direction of the vehicle body. The two ends of each sub-beam body in the extending direction can be respectively connected to two adjacent cross beams 2. A cross beam 2 is arranged between two adjacent sub-beam bodies. Thus, multiple sub-beam bodies can connect multiple cross beams 2, and multiple sub-beam bodies and multiple cross beams 2 form a cross structure to effectively improve the load-bearing capacity and stability of the entire roof cover 100. By adopting the method of using multiple sub-beam bodies to form the connecting beam 3, on the one hand, on the premise of ensuring the structural strength of the roof cover 100, unnecessary material use in the cross region between the connecting beam 3 and the cross beam 2 can be reduced, the overall weight can be reduced, which helps to realize the lightweight of the roof cover 100; on the other hand, multiple sub-beam bodies can be constructed as common parts. In this way, the convenience and efficiency of processing and manufacturing the connecting beam 3 can be improved, and it is beneficial to improve the versatility of the connecting beam 3 applied to different vehicles 200; on the third hand, the separate installation and arrangement of multiple sub-beam bodies have higher flexibility than the installation of a single integral connecting beam 3, which can improve the assembly efficiency and assembly convenience. Moreover, when a certain sub-beam body is damaged or needs to be replaced, it can be replaced separately without affecting the entire connecting beam 3 or other parts of the roof cover 100, thereby reducing the maintenance cost and difficulty.

[0046] In addition, in some specific embodiments of the present application, the number of the cross beams 2 is configured to be five, which are respectively a front cross beam 2a and a rear cross beam 2b located at both ends of the body 1, and three intermediate beams 2c sequentially arranged between the front cross beam 2a and the rear cross beam 2b. The number of the sub-beam bodies is configured to be four, which are respectively two first sub-beam bodies 31 and two second sub-beam bodies 32. The first sub-beam bodies 31 are arranged between the intermediate beams 2c, and the second sub-beam bodies 32 are arranged between the front cross beam 2a and the intermediate beam 2c and between the rear cross beam 2b and the intermediate beam 2c. By configuring the number of the cross beams 2 to be five and the number of the sub-beam bodies to be four, the number of the sub-beam bodies and the cross beams 2 is appropriate, which can realize the lightweight of the roof cover 100 while playing a good strengthening role for the roof cover 100. Moreover, the multiple sub-beam bodies are divided into two types, namely the first sub-beam bodies 31 and the second sub-beam bodies 32. While the sub-beam bodies can be connected to multiple cross beams 2, the sub-beam bodies can be two common parts, which is beneficial to improve the adaptability and versatility of the connecting beam 3.

[0047] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, the body 1 and the connecting beam 3 are adhesively bonded.

[0048] Specifically, the connecting beam 3 and the body 1 can be connected by an adhesive bonding method. Exemplarily, an expansion rubber strip can be pre-set on the connecting beam 3. When the connecting beam 3 and the body 1 are assembled, a fixed connection can be achieved through the expansion rubber strip. By adopting the adhesive bonding method, on the one hand, by fitting the bonded parts of the connecting beam 3 and the body 1, the connection and fixation of the two can be realized, and the connection problem of the middle area on the body 1 where spot welding cannot be performed can be solved; on the other hand, by adopting the adhesive bonding method, it can be ensured that the connecting beam 3 and the body 1 can be firmly connected, the damping effect can be enhanced, and the appearance quality will not be affected, improving the styling quality performance of the top cover 100.

[0049] In addition, the adhesive bonding method also has the advantages of good adaptability to complex curved surfaces, reliable connection, convenient installation, small stress, and low cost. By setting the body 1 and the connecting beam 3 to be connected by the adhesive bonding method, it is beneficial to improve the connection efficiency, connection stability, and force dispersion performance between the body 1 and the connecting beam 3, and it is also beneficial to save economic costs.

[0050] Furthermore, in some specific embodiments of the present application, first adhesive bonding portions 3b are formed on both sides of the connecting beam 3 in the width direction, which are opposite to the body 1 in the thickness direction of the body 1. The first adhesive bonding portions 3b can be provided with adhesive bonding members (such as expansion rubber strips), so as to achieve a firm connection between the connecting beam 3 and the body 1 without affecting the appearance quality. Moreover, the first adhesive bonding portions 3b are located on both sides of the connecting beam 3 in the width direction, which is equivalent to that both side regions of the connecting beam 3 in the width direction can be adhesively bonded to the body 1. In this way, the adhesive bonding area between the connecting beam 3 and the body 1 can be increased and the connection points can be increased, which can further enhance the connection strength and stability between the connecting beam 3 and the body 1 and improve the working reliability of the connecting beam 3.

[0051] In other specific embodiments of the present application, second adhesive bonding portions 21 are formed on both sides of the cross beam 2 in the width direction. The second adhesive bonding portions 21 are adhesively bonded to the body 1, and both ends of the cross beam 2 in the extending direction are welded to both sides of the body 1 in the width direction, for example, by spot welding. In this way, the connection stability between the cross beam 2 and the body 1 can be improved.

[0052] As Figures 1 - 3 shown, according to some embodiments of the present application, both ends of each sub-beam body have connecting flanges, and the connecting flanges are welded to the cross beam 2.

[0053] Specifically, both ends of each sub-beam body in the extending direction can be provided with connecting flanges, and the connecting flanges can be connected to the adjacent cross beam 2 by welding, so as to realize the connection between the sub-beam body and the cross beam 2. Moreover, the adopted welding connection method is firm and reliable, which can ensure the stability of the connection between the sub-beam body and the cross beam 2 when bearing various forces and vibrations, and can effectively improve the overall stability and safety of the top cover 100.

[0054] Preferably, the connecting flange on the sub-beam body and the cross beam 2 are welded together by a tailor welded blank to ensure the welding strength and stability between the sub-beam body and the cross beam 2. Moreover, by being welded together by a tailor welded blank, splicing of different materials with different material thicknesses can be satisfied according to performance requirements. Therefore, the material utilization rate can be improved, costs can be saved, and the stiffness and strength of the top cover 100 can be further enhanced.

[0055] As Figure 3 shown, according to some embodiments of the present application, a weight-reducing hole 3a is formed on each sub-beam body.

[0056] Specifically, the number of weight-reducing holes 3a on each sub-beam body can be one or more. The weight-reducing holes 3a can penetrate the sub-beam body in the thickness direction of the sub-beam body. The weight-reducing holes 3a can be, but are not limited to, configured as circular holes, oval holes, etc. By providing the weight-reducing holes 3a, on the one hand, the amount of material used can be reduced, production costs can be saved, the weight of the connecting beam 3 can be reduced, and the light weight of the top cover 100 can be improved; on the other hand, by providing the weight-reducing holes 3a, the structural strength and stiffness of the sub-beam body itself can also be enhanced, which helps to further improve the load-bearing capacity and stability of the connecting beam 3.

[0057] In addition, in some specific embodiments of the present application, the weight-reducing holes 3a on each sub-beam body are configured as multiple, and the multiple weight-reducing holes 3a are arranged at intervals along the extending direction of the sub-beam body to achieve a good weight-reducing effect and ensure good structural stiffness.

[0058] As Figure 1 、 Figure 2 and Figure 4 shown, according to some embodiments of the present application, reinforcing ribs 4 are provided on the body 1.

[0059] Specifically, reinforcing ribs 4 can be provided on the body 1. The reinforcing ribs 4 can increase the bending resistance, torsional resistance and shear resistance of the structure. The reinforcing ribs 4 can extend along a specific path to form strip-shaped, mesh-shaped or other shapes, etc., so as to strengthen the areas prone to deformation (such as the center, edges, etc. of the body 1), thereby enhancing the strength of the local stress-bearing area of the body 1 and improving the anti-deformation ability of the top cover 100. By providing the reinforcing ribs 4, the overall structural stiffness of the top cover 100 can also be improved, the stability and durability of the overall structure of the top cover 100 can be improved, and further help to improve the NVH performance of the vehicle 200, and improve the driving stability and safety.

[0060] As Figure 4 shown, according to some embodiments of the present application, the reinforcing rib 4 includes: a first reinforcing rib 41, and the first reinforcing rib 41 extends along the length direction of the body 1, and is provided at the length center line of the body 1 and is located on both sides of the width center line of the body 1.

[0061] Specifically, the first reinforcing rib 41 can be provided at the length midline of the body 1 and extend in the length direction of the body 1 to enhance the rigidity and strength of the roof cover 100 in the length direction. During the driving of the vehicle 200, the roof cover 100 may be subjected to impacts and vibrations from the road surface, and these forces often transmit along the length direction of the vehicle body. Therefore, arranging the first reinforcing rib 41 along the length direction on the body 1 of the roof cover 100 can effectively resist the deformation caused by these forces and maintain the shape stability of the roof cover 100. At the same time, the first reinforcing rib 41 is located on both sides of the width midline of the body 1 and is symmetric about the width midline of the body 1. In this way, the balance and stability of the roof cover 100 in the width direction can be optimized.

[0062] It should be noted that the distance between the first reinforcing rib 41 and the width midline of the body 1 can be correspondingly designed according to the force conditions and material properties of different roof covers 100 to ensure sufficient support in the key stress areas.

[0063] As Figure 4 shown, according to some embodiments of the present application, the reinforcing rib 4 further includes: the second reinforcing rib 42 is symmetrically arranged about the width midline of the body 1, and one end of the second reinforcing rib 42 is connected to the end of the first reinforcing rib 41, and the other end is far from the first reinforcing rib 41 and extends obliquely close to the length midline of the body 1 in the direction towards the length edge of the body 1.

[0064] Specifically, the second reinforcing rib 42 can be symmetrically arranged about the width midline of the body 1 so that the forces on the roof cover 100 in the width direction are balanced, thereby enhancing the overall stability and anti-deformation ability of the roof cover 100. One end of the second reinforcing rib 42 can be connected to the end of the first reinforcing rib 41 to ensure the continuity of the reinforcing rib 4 and jointly bear and disperse the loads from different directions, thereby improving the load-bearing capacity of the roof cover 100. The other end of the second reinforcing rib 42 is far from the first reinforcing rib 41 and extends obliquely close to the length midline of the body 1 in the direction towards the length edge of the body 1, so that the second reinforcing rib 42 and the first reinforcing rib 41 can form a structure similar to a triangle. By using the stability principle of the triangle structure, the bending resistance of the roof cover 100 in the width direction and the length direction can be further improved. At the same time, the oblique extension of the second reinforcing rib 42 also helps to guide and disperse the loads, reduce the occurrence of local stress concentration phenomena, and effectively improve the load-bearing capacity and bending resistance of the roof cover 100 in all directions.

[0065] As Figure 4As shown, according to some embodiments of the present application, the reinforcing rib 4 further includes: a third reinforcing rib 43, which is symmetrically arranged about the width median line of the body 1. One end of the third reinforcing rib 43 is connected to the end of the second reinforcing rib 42 in the vehicle body length direction. The other end of the third reinforcing rib 43 is away from the first reinforcing rib 41 and extends obliquely towards the length edge of the body 1.

[0066] Specifically, the third reinforcing rib 43 can be symmetrically arranged about the width median line of the body 1. The symmetrical layout of the third reinforcing rib 43 can ensure the even stress distribution of the roof cover 100 in the width direction, which helps to improve the overall stability and anti-deformation ability of the final product. One end of the third reinforcing rib 43 is connected to the end of the second reinforcing rib 42 in the vehicle body length direction, so that the third reinforcing rib 43, the second reinforcing rib 42 and the first reinforcing rib 41 together form a continuous and multi-directional reinforcing structure on the roof cover 100, similar to an "X-X" shaped structure. And this "X-X" structure covers the length direction and width direction of the body 1, so that there is no large-scale flat structure in the whole roof cover 100, compensating for the problem of insufficient stiffness of the roof cover 100 caused by the small bi-directional curvature due to the styling. The reinforcing ribs 4 work together to jointly bear and disperse the loads from different directions, effectively enhancing the anti-deformation ability of the roof cover 100 in the length direction and width direction. At the same time, the layout of the third reinforcing rib 43, the second reinforcing rib 42 and the first reinforcing rib 41 increases the length of the position where the reinforcing rib 4 is located in the vehicle body height direction. In this way, the drawing of the roof cover 100 in the length direction and width direction can be more sufficient, which can improve the stiffness of the roof cover 100 after stamping, improve the anti-denting performance of the roof cover 100, and thus improve the NVH performance and safety of the vehicle 200.

[0067] It should be noted that at least part of the third reinforcing rib 43 and the second reinforcing rib 42 near the length edge of the body 1 extend in the vehicle body length direction to ensure the continuity and structural stability of the reinforcing rib 4, and to provide additional support for the area near the edge of the roof cover 100 to enhance the anti-deformation ability of the roof cover 100 edge.

[0068] As Figure 1 shown, the vehicle 200 according to the second aspect embodiment of the present application includes: the roof cover 100 described in any one of the above embodiments, and the technical effects generated are the same as those in the above embodiments, which will not be elaborated here.

[0069] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.
