Description

Technical Field

[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 automotive industry's pursuit of lightweight design, 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-directional curvature. This design meets the streamlined appearance of the vehicle aesthetically, but poses challenges mechanically. Due to the lightweight requirement, the thickness of the roof has been significantly reduced. Coupled with the small curvature resulting in insufficient drawing of the stamping parts during manufacturing, it directly causes a significant decrease in the stiffness of the roof. Currently, reinforcing rib groups are often arranged in sequence in the length direction of the roof in order to improve the structural stiffness and strength. However, due to the need of the stamping process, the thickness of the reinforcing ribs usually gradually changes from a certain initial thickness to zero, which further exacerbates the problem of poor stiffness in the area where the reinforcing rib groups are close to each other, further reducing the dent resistance. This area is extremely prone to denting under external forces and is also prone to vibration and noise, seriously affecting the safety performance of the entire vehicle and the NVH (Noise, Vibration, Harshness) performance. Summary of the Utility Model

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, an object of the present application is to provide a vehicle roof. By providing connecting beams, the stiffness of the interval area between the reinforcing rib groups can be enhanced, effectively improving the anti-deformation ability of the interval area, enhancing the overall structural strength and stiffness of the roof, enabling the roof to take into account good dent resistance and the lightweight styling requirements, and optimizing the safety performance of the entire vehicle and the NVH performance.

The body is provided with at least two groups of reinforcing ribs arranged in sequence along the vehicle body length direction; the connecting beams are connected to the body and at least span the interval area between adjacent two groups of the reinforcing ribs.

[0006] According to the roof cover of the present application, by providing connecting beams, the problem of insufficient stiffness in the spaced areas between the reinforcing rib groups can be solved, deformation or damage caused by excessive force in local areas can be prevented, and the anti-deformation ability can be effectively improved. At the same time, the connecting beams also enhance the overall structural strength and stiffness of the roof cover. On the basis of ensuring that the roof cover meets the requirements of anti-denting and anti-bending and torsion resistance, more possibilities can be provided for the roof cover to tend to have a small double curvature and a lightweight design, enabling the roof cover to balance good anti-deformation performance and the need for a thin and light shape, and optimizing the vehicle safety performance and NVH performance.

[0044] Reference is made below to Figures 1 - 5 describe the top cover 100 and the vehicle 200 according to the embodiments of the present application.

[0045] As Figure 2 and Figure 3 shown, the top cover 100 according to the first aspect embodiment of the present application, the top cover 100 includes: a main body 1 and a connecting beam 2.

[0046] Wherein, at least two groups of reinforcing ribs 11 are sequentially arranged on the main body 1 along the vehicle body length direction; the connecting beam 2 is connected to the main body 1 and at least straddles the interval area between adjacent two groups of reinforcing ribs 11.

[0047] Specifically, the body 1 is the main structure of the roof cover 100, which is used to cover and protect the top of the vehicle body. There are at least two sets of reinforcing ribs 11 arranged in sequence along the length direction of the vehicle body on the body 1. It can be understood that each set of reinforcing ribs 11 is arranged at intervals in the length direction of the vehicle body with the adjacent set of reinforcing ribs 11. The quantity and position of each set of reinforcing ribs 11 can be arranged according to the requirements of the roof cover 100 and the vehicle body structure. The reinforcing ribs 11 can enhance the strength and stiffness of the roof cover 100 and improve the anti-deformation ability of the roof cover 100. The connecting beam 2 is fixed on the body 1. The connecting beam 2 can extend in the length direction of the vehicle body and at least span the interval area between two adjacent sets of reinforcing ribs 11. The connecting beam 2 can provide additional support for the interval area between the sets of reinforcing ribs 11 to effectively share and resist the influence of external forces on the interval area, and can prevent deformation or damage caused by excessive local stress. At the same time, the connecting beam 2 connects the adjacent sets of reinforcing ribs 11 to form a more stable overall reinforcing structure, which can further enhance the overall structural strength, stiffness and stability of the roof cover 100.

[0048] It should be noted that the connecting beam 2 is configured as a general component, which can be applied to different roof covers 100 and different vehicles 200. In this way, the mold development cost and the production cost per vehicle can be saved, and it is beneficial to simplify the installation and maintenance operations of the connecting beam 2, and the production efficiency and maintenance efficiency of the vehicle 200 can be improved.

[0049] For the roof cover 100 according to the present application, by setting the connecting beam 2, the problem of insufficient stiffness in the interval area between the sets of reinforcing ribs 11 can be solved, the deformation or damage caused by excessive stress in the local area can be prevented, and the anti-deformation ability can be effectively improved. At the same time, the connecting beam 2 also enhances the overall structural strength and stiffness of the roof cover 100. On the basis of ensuring that the roof cover 100 meets the requirements of anti-denting and anti-bending and torsion resistance, more possibilities can be provided for the roof cover 100 to tend to a small double curvature and lightweight design, so that the roof cover 100 can take into account good anti-deformation performance and thin and light styling requirements, and optimize the overall vehicle safety performance and NVH performance.

[0050] As Figure 2 and Figure 3 shown, according to some embodiments of the present application, there are multiple connecting beams 2, and the multiple connecting beams 2 are arranged in sequence along the width direction of the vehicle body.

[0051] Specifically, the connecting beams 2 can be configured as multiple ones arranged at intervals in the vehicle body width direction. The multiple connecting beams 2 can further enhance the strength and stiffness of the roof cover 100, especially the strength and stiffness of the interval area between adjacent groups of reinforcing ribs 11, thereby effectively solving the problem of insufficient stiffness caused by the reduced sheet thickness due to the shaping requirements of the roof cover 100 and the stamping process of the reinforcing ribs 11. In addition, arranging the multiple connecting beams 2 at intervals in the vehicle body width direction helps to improve the uniformity of load distribution when the roof cover 100 is subjected to external forces, can avoid local stress concentration, and thus can effectively improve the stability and safety of the overall structure of the roof cover 100.

[0052] It should be noted that the number of the connecting beams 2 and the layout spacing between adjacent connecting beams 2 can be adjusted according to the specific requirements of different vehicle models to improve the flexibility and versatility of the application of the connecting beams 2 to different vehicles 200.

[0053] Preferably, the number of the connecting beams 2 is configured as two, and the two connecting beams 2 are arranged at intervals in the width direction of the body 1, so as to achieve lightweight while ensuring good structural strength and uniform load distribution of the roof cover 100.

[0054] As Figure 2 shown, according to some embodiments of the present application, the body 1 and the connecting beam 2 are adhesively bonded.

[0055] Specifically, the connecting beam 2 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 2, and when the connecting beam 2 and the body 1 are assembled, the fixed connection can be achieved through the expansion rubber strip. By adopting the adhesive bonding method, on the one hand, by fitting the bonded part 22 of the connecting beam 2 and the body 1, the connection and fixation of the two can be achieved, and the connection problem that the body 1 cannot be spot-welded can be solved; on the other hand, by adopting the adhesive bonding method, it can be ensured that the connecting beam 2 and the body 1 can be firmly connected and the appearance quality will not be affected, improving the shaping quality performance of the roof cover 100.

[0056] 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 2 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 2, and is also beneficial to saving economic costs.

[0057] As Figure 5 shown, according to some embodiments of the present application, the connecting beam 2 includes: a body portion 21 and a bonded portion 22.

[0058] Among them, the body part 21 extends in the vehicle body length direction, the body part 21 protrudes away from the body 1 and defines a cavity, and bonding parts 22 are provided on both sides of the body part 21 in the width direction, and the bonding parts 22 are adapted to be bonded to the body 1.

[0059] Specifically, the body part 21 can extend in the vehicle body length direction and serve as the main support structure of the connecting beam 2. The body part 21 protrudes away from the body 1 in the thickness direction of the body 1 and defines a cavity. In this way, the strength of the connecting beam 2 can be enhanced, the force dispersion performance of the connecting beam 2 can be optimized, and it is beneficial to reduce the cost and weight of the connecting beam 2; a bonding surface can be formed on the side of the bonding part 22 facing the body 1 to install a bonding part (such as an expansion rubber strip), so as to realize a firm connection between the connecting beam 2 and the body 1 without affecting the appearance quality. Moreover, the bonding parts 22 are located on both sides of the body part 21 in the width direction, which is equivalent to that both sides of the connecting beam 2 in the width direction can be bonded to the body 1. In this way, the bonding area between the connecting beam 2 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 2 and the body 1, and improve the working performance and service life of the roof cover 100.

[0060] As Figure 5 shown, according to some embodiments of the present application, a weight reduction hole 21a is formed on the body part 21.

[0061] Specifically, the number of the weight reduction holes 21a can be one or more. The weight reduction holes 21a can penetrate the body part 21 in the thickness direction of the body part 21 and extend in the vehicle body length direction. By providing the weight reduction holes 21a, on the one hand, the use of materials can be reduced, the production cost can be saved, the weight of the connecting beam 2 can be reduced, and the light weight of the roof cover 100 can be improved; on the other hand, the weight reduction holes 21a can also enhance the structural strength and stiffness of the body part 21, which is helpful to further improve the bearing capacity and stability of the connecting beam 2.

[0062] In addition, in some specific embodiments of the present application, the weight reduction holes 21a are configured as two, and the two weight reduction holes 21a are spaced apart in the extending direction of the body part 21 to achieve a good weight reduction effect.

[0063] In some other specific embodiments of the present application, the weight reduction holes 21a are configured as elongated holes to optimize the stress distribution and match the shape contour of the body part 21.

[0064] As Figure 5 shown, according to some embodiments of the present application, the body part 21 has positioning parts 21b at both ends in the extending direction.

[0065] Specifically, the body portion 21 has positioning portions 21b at both ends in the extending direction. The positioning portions 21b can be configured as positioning holes or positioning posts. The positioning portions 21b can be used to play a good positioning and guiding role. For example, during the stamping process, the positioning portions 21b can satisfy the positioning and matching of the connecting beam 2 with the mold to ensure the accurate forming of the connecting beam 2 and the entire top cover 100. The positioning portions 21b can also be used to ensure the accurate docking of the connecting beam 2 with the body 1 and other related components, which can avoid installation problems caused by position deviation, improve the installation accuracy of the connecting beam 2 and the entire top cover 100. By providing the positioning portions 21b, the production efficiency and the overall assembly efficiency can also be improved.

[0066] As Figure 5 shown, according to some embodiments of the present application, a first connecting portion 23 and a second connecting portion 24 are respectively provided at both ends of the body portion 21, and the first connecting portion 23 and the second connecting portion 24 extend away from each other.

[0067] Specifically, the first connecting portion 23 and the second connecting portion 24 are respectively located at both ends of the body portion 21 in the extending direction, and the first connecting portion 23 and the second connecting portion 24 extend in a direction away from each other, so that the first connecting portion 23 and the second connecting portion 24 can be connected to other components (such as the rear crossbeam structure assembly of the top cover 100, etc.). It can be understood that the first connecting portion 23 and the second connecting portion 24 provide additional installation points for the installation and fixation of the connecting beam 2. In this way, the installation reliability and stability of the connecting beam 2 can be further improved, and the stress dispersion performance can be enhanced. Furthermore, the overall structural strength and stiffness of the top cover 100 can be improved, and the NVH performance can be optimized.

[0068] Furthermore, mounting holes can be formed on both the first connecting portion 23 and the second connecting portion 24. The mounting holes are adapted to cooperate with the fasteners 4 to connect the first connecting portion 23 and the second connecting portion 24 to other components respectively. Among them, the fasteners 4 can be bolts, screws, etc. Adopting the method of cooperating the fasteners 4 with the mounting holes is beneficial to improving the connection reliability and also facilitates the assembly, maintenance, and replacement of the connecting beam 2.

[0069] Preferably, in some specific embodiments of the present application, other components (such as the rear crossbeam structure assembly of the top cover 100, etc.) connected to the first connecting portion 23 and the second connecting portion 24 are provided with welding nuts. The mounting holes of the first connecting portion 23 and the second connecting portion 24 are bolt-connected to the welding nuts to achieve the stable connection of the connecting beam 2 with the rear crossbeam structure assembly of the top cover 100, etc.

[0070] As Figure 5 shown, according to some embodiments of the present application, the projected contour dimensions of the first connecting portion 23 and the second connecting portion 24 in the vehicle body height direction are different.

[0071] Specifically, the projection shapes and sizes of the first connecting portion 23 and the second connecting portion 24 in the vehicle body height direction are different, which can be understood as a differential design of the sizes of the first connecting portion 23 and the second connecting portion 24. In this way, the connection positions of the two ends of the connecting beam 2 with other components can be different, which can improve the flexibility of the connecting beam 2 during the assembly process with other components, can play a good role in preventing assembly mistakes, can reduce errors or rigidities during the assembly process, and thus can effectively improve the assembly efficiency and assembly accuracy of the connecting beam 2.

[0072] As Figures 1 - 4 shown, according to some embodiments of the present application, the roof cover 100 further includes: a plurality of cross beams 3 arranged in sequence along the vehicle body length direction, and the two ends of the connecting beam 2 are respectively connected to two cross beams 3.

[0073] Specifically, the plurality of cross beams 3 can be arranged at intervals in sequence along the vehicle body length direction. By arranging these cross beams 3, the strength and stiffness of the roof cover 100 can be enhanced, and the plurality of cross beams 3 can effectively disperse and bear the forces from above or the side, such as collision forces, wind pressure, etc., so as to protect the safety of the passengers in the vehicle and improve safety. The number, position, cross-sectional shape, etc. of the cross beams 3 can be selected and optimized differently according to the specific design and safety standards of the vehicle 200. Among them, the two ends (i.e., the first connecting portion 23 and the second connecting portion 24) of the connecting beam 2 are respectively connected to two cross beams 3. Here, the two cross beams 3 can be two adjacent cross beams 3, or two cross beams 3 with other cross beams 3 in between. It can be understood that the layout of the connecting beam 2 can cover two cross beams 3 or more than two cross beams 3. The embodiments of the present application do not limit this, and the connecting beam 2 only needs to span at least the interval area between two adjacent sets of reinforcing ribs 11.

[0074] By arranging the two ends of the connecting beam 2 to be respectively connected to two cross beams 3, on the one hand, the installation stability of the connecting beam 2 can be increased, and the working reliability of the connecting beam 2 can be improved; on the other hand, the connecting beam 2 can strengthen the connection between the cross beams 3, so that the plurality of cross beams 3 form a more stable overall structure, which helps to further improve the overall stability and load-bearing capacity of the roof cover 100, and further enhance the overall safety and NVH performance of the vehicle 200.

[0075] In addition, as Figure 2 and Figure 3 shown, in some specific embodiments of the present application, one of the plurality of cross beams 3 is configured as the middle-rear cross beam 32 of the roof cover, and the other of the plurality of cross beams 3 is configured as the rear cross beam 31 of the roof cover. The first connecting portion 23 of the connecting beam 2 is connected to the middle-rear cross beam 32 of the roof cover through a fastener 4, and the second connecting portion 24 is connected to the rear cross beam 31 of the roof cover through a fastener 4 to achieve improving the installation stability of the connecting beam 2.

[0076] As shown Figure 1 As shown, the vehicle 200 according to the embodiment of the second aspect 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 herein.
