[0002] With the development and growth of the vehicle market, vehicle technologies have been continuously developed and matured, and consumers' requirements for vehicle driving comfort have also become higher and higher. The NVH (Noise, Vibration, Harshness) characteristics give the most direct and obvious feelings to vehicle users.
[0003] In related technologies, due to the continuous trend of vehicle lightweight and low-cost design, but the NVH performance cannot decline. Under such a premise, when existing vehicles are tested on roads, there is a problem that the rear part of the sunroof frame of the vehicle body has a relatively large vibration frequency, resulting in a poor driving experience for users. Summary of the Utility Model
[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the utility model is to provide a sunroof frame, which can increase the weight and spatial mode of the rear crossbeam, so as to enhance the structural strength of the rear crossbeam and reduce the vibration amplitude of the rear crossbeam.

When the natural frequency of the rear crossbeam is far from the excitation frequency in the environment, the rear crossbeam is not easy to generate resonance, so as to reduce the vibration amplitude of the rear crossbeam), thereby improving the driving comfort of the vehicle.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary.
[0030] The following references Figures 1-5Describe the awning frame 100 according to an embodiment of the present utility model, which can increase the weight and spatial mode of the rear crossbeam 1, so as to achieve the effects of enhancing the structural strength of the rear crossbeam 1 and reducing the vibration amplitude of the rear crossbeam 1.
[0031] Combined with Figures 1-5 As shown in the figure, the awning frame 100 according to the first aspect embodiment of the present utility model includes a rear crossbeam 1 and a reinforcing plate 2. Among them, the rear crossbeam 1 mainly serves as a supporting structural member of the outer contour of the awning frame 100, and the reinforcing plate 2 can play the role of increasing the structural strength of the rear crossbeam 1 and reducing the vibration amplitude of the rear crossbeam 1.
[0032] Specifically, a reinforcing structure 11 is provided at the front part of the rear crossbeam 1. The reinforcing plate 2 is arranged on the rear crossbeam 1, and the reinforcing plate 2 is arranged opposite to the reinforcing structure 11 up and down. The reinforcing plate 2 and the reinforcing structure 11 jointly form a cavity 21, and the longitudinal section of the cavity 21 is in a closed shape. It can be understood that in the front-rear direction, a reinforcing structure 11 for enhancing its own structural strength is provided at the front part of the rear crossbeam 1, so as to improve the structural reliability of the rear crossbeam 1; the reinforcing plate 2 is connected to the rear crossbeam 1, and the reinforcing plate 2 and the reinforcing structure 11 are arranged opposite to each other in the up-down direction. In this way, the weights of the rear crossbeam 1 and the reinforcing plate 2 can be increased, and the spatial mode at the position of the reinforcing structure 11 on the rear crossbeam 1 can be effectively enhanced. On the one hand, it can improve the structural strength and flexural and torsional stiffness of the rear crossbeam 1, and on the other hand, it can also reduce the vibration amplitude of the rear crossbeam 1 and attenuate its vibration energy (since the natural frequency of a mechanical structure depends on its mass and stiffness, the effect of increasing the mass and stiffness of the rear crossbeam 1 can be achieved by connecting the reinforcing plate 2 to the rear crossbeam 1 in this case, so as to reduce the natural frequency of the rear crossbeam 1. When the natural frequency of the rear crossbeam 1 is far from the excitation frequency in the environment, the rear crossbeam 1 will not easily generate resonance, and thus the vibration amplitude of the rear crossbeam 1 can be reduced), thereby improving the ride comfort of the vehicle.
[0033] Among them, the longitudinal section structure of the cavity 21 jointly formed by the reinforcing plate 2 and the reinforcing structure 11 is in a closed shape, so that a closed force transmission path can be formed between the reinforcing plate 2 and the rear crossbeam 1, which helps to disperse the loads received by each other, thereby effectively improving the structural reliability of the rear crossbeam 1 at the position of the reinforcing structure 11.
[0034] In addition, compared with the arrangement method of increasing the damping structure, the reinforcing plate 2 in this case can achieve an effective damping effect without excessively increasing the weight of the rear crossbeam 1, thus taking into account the lightweight design effect and damping effect of the awning frame 100 at the same time.
[0035] Thus, by setting the awning frame 100, the weight and spatial mode of the rear crossbeam 1 can be increased, thereby achieving the effects of enhancing the structural strength of the rear crossbeam 1 and reducing the vibration amplitude of the rear crossbeam 1, and further improving the structural reliability of the whole vehicle and the riding comfort of users.
[0036] According to some alternative embodiments of the present invention, in combination with Figure 1 and Figure 5 as shown, the reinforcing plate 2 is connected to the lower surface of the rear crossbeam 1, and the longitudinal section of the reinforcing plate 2 is configured in an arch shape with higher sides and a lower middle.
[0037] Among them, since the arch structure can effectively convert the vertical load (the load in the up and down directions) into a horizontal thrust and can be transmitted to the support structure (that is, the rear crossbeam 1) through the arch feet, the arch structure has high structural stability and load-bearing capacity, and the layout method in this case can effectively improve the structural reliability of the reinforcing plate 2.
[0038] According to some alternative embodiments of the present invention, in combination with Figure 1 and Figure 5 as shown, in the front-to-back direction, the reinforcing structure 11 is located at the one-third position in the width direction of the rear crossbeam 1, and the reinforcing structure 11 protrudes away from the reinforcing plate 2.
[0039] Among them, with the above layout, the bending and torsion resistance of the rear crossbeam 1 at the one-third position in its width direction (in the front-to-back direction) can be effectively enhanced, thereby improving the structural strength of the local position of the rear crossbeam 1; it can also reduce the use of materials while ensuring the satisfaction of the structural strength requirements, thereby reducing the overall weight and cost; in summary, the reinforcing structure 11 can prevent the rear crossbeam 1 from undergoing local deformation or buckling when subjected to concentrated loads or impacts, thereby improving the overall structural stability and safety of the rear crossbeam 1. For example, the reinforcing structure 11 can be configured as a reinforcing rib extending along the length direction of the rear crossbeam 1.
[0040] According to some alternative embodiments of the present invention, in combination with Figure 2 、 Figure 3 and Figure 5 as shown, a first connecting portion 22 is provided at the rear side of the reinforcing plate 2, and the first connecting portion 22 is welded to the rear crossbeam 1.
[0041] Specifically, a first connecting portion 22 for welding connection with the rear cross member 1 is provided at the rear side of the reinforcing plate 2, so that the reinforcing plate 2 and the rear cross member 1 can be connected into a firm whole, thereby ensuring the connection reliability between the two. Among them, compared with connection methods such as screwing and riveting, welding connection has the characteristics of higher connection strength and greater connection flexibility (it can be connected between complex shapes and structures without considering the position and size limitations of fasteners). In addition, welding connection can also reduce the assembly time and improve the production efficiency.
[0042] Optionally, as shown in Figure 2 , Figure 3 and Figure 5 , a second connecting portion 23 is provided at the front side of the reinforcing plate 2, and the second connecting portion 23 is welded to the rear cross member 1. It can be understood that a second connecting portion 23 for welding connection with the rear cross member 1 is provided at the front side of the reinforcing plate 2, so that the reinforcing plate 2 and the rear cross member 1 can be connected into a firm whole, thereby ensuring the connection firmness between the two. Moreover, compared with connection methods such as screwing and riveting, welding connection can, on the one hand, improve the connection strength between the two, thereby improving the connection reliability between the rear cross member 1 and the reinforcing plate 2; on the other hand, it can also save the layout space occupied by fasteners and the assembly time spent, thereby improving its production and assembly efficiency.
[0043] For example, the reinforcing plate 2 and the front side position of the rear cross member 1 are connected through 10 welding points (that is, the second connecting portion 23). Since the connection position is at the edge in the width direction of the rear cross member 1, such an arrangement can increase the connection strength between the two while also increasing the structural strength of the upper edge position of the rear cross member 1 and the reinforcing plate 2.
[0044] Specifically, as shown in Figure 2 , Figure 3 and Figure 5 , a plurality of weight reduction holes 12 spaced in the left - right direction are provided at the rear side of the rear cross member 1. The first connecting portion 22 is plural, and the plurality of first connecting portions 22 include end connecting portions 221 and middle connecting portions 222, and the end connecting portions 221 are respectively located at the left and right ends of the reinforcing plate 2.
[0045] That is to say, along the left - right direction, a plurality of weight reduction holes 12 are spaced at the rear side of the rear cross member 1. In this way, on the basis of meeting the structural strength of the rear side position of the rear cross member 1, the weight of the rear cross member 1 can be reduced, thereby achieving the lightweight design effect of the rear cross member 1.
[0046] Among them, the end connecting portions 221 at the left and right ends of the reinforcing plate 2 are connected to the rear cross member 1, so that the end connecting portions 221 can effectively enhance the connection strength at the weak force - bearing positions at the edges of the reinforcing plate 2, thereby improving the overall structural reliability of the reinforcing plate 2 and the cross member.
[0047] In addition, the middle connecting portion 222 is located in the middle of the reinforcing plate 2. The middle connecting portion 222 is respectively connected to one-third and / or two-thirds of the length direction of the weight-reducing hole 12 on the corresponding rear cross member 1, so that the stress borne at the weight-reducing hole 12 corresponding to the middle connecting portion 222 can be more evenly distributed, thereby avoiding the risk of excessive local stress concentration at the weight-reducing hole 12, and further taking into account the lightweight design effect and structural reliability of the rear cross member 1 at the same time.
[0048] Furthermore, as shown in Figure 2 , Figure 3 and Figure 5 the first connecting portion 22 further includes a side connecting portion 223. Along the left-right direction of the vehicle, the side connecting portion 223 is located at one-fourth or three-fourths of the length direction of the reinforcing plate 2, and the side connecting portion 223 is connected to one-third or two-thirds of the length direction of the weight-reducing hole 12 corresponding thereto.
[0049] It can be understood that such an arrangement can increase the connection force-bearing positions between the reinforcing plate 2 and the rear cross member 1 at different positions along its length direction, thereby improving the connection stability between the reinforcing plate 2 and the rear cross member 1; it can also more evenly distribute the stress borne at the weight-reducing hole 12 corresponding to the side connecting portion 223, thereby avoiding the risk of excessive local stress concentration at the weight-reducing hole 12, and further taking into account the lightweight design effect and structural reliability of the rear cross member 1 at the same time.
[0050] For example, the rear side position of the reinforcing plate 2 and the rear cross member 1 is connected by 6 welding points. There is one welding point at each of the left and right ends (that is, the end connecting portion 221), and there are two welding points at the middle force-bearing weak position of the rear cross member 1 (that is, the middle connecting portion 222), and these two welding points are located at the one-third force-bearing weak positions on the left and right sides of the weight-reducing hole 12 of the corresponding rear cross member 1, so that the structural strengthening of the two force-bearing weak positions of the reinforcing plate 2 and the weight-reducing hole 12 of the rear cross member 1 can be achieved simultaneously; there is one welding point at each of the one-fourth weak positions in the length direction of the reinforcing plate 2 (that is, the side connecting portion 223), and this welding point is located at the one-third force-bearing weak positions on the left and right sides of the weight-reducing hole 12 of the corresponding rear cross member 1, so that the structural strengthening of the two force-bearing weak positions of the reinforcing plate 2 and the weight-reducing hole 12 of the rear cross member 1 can be further achieved simultaneously.
[0051] According to some alternative embodiments of the present invention, as shown in Figure 4 a plurality of downwardly protruding arched convex structures 24 are provided at least on one side of the reinforcing plate 2 in the front-rear direction of the vehicle at intervals, and the ratios of the height-width ratios of the plurality of arched convex structures 24 are different.
[0052] Specifically, in the left - right direction of the whole vehicle, a plurality of arched convex structures 24 with different height - width ratios are provided on the reinforcing plate 2. The height - width ratio of the arched convex structure 24 refers to the ratio of the rise of the arch to the length of the arch. The rise is the vertical height from the crown of the arch to the springing, that is, the dimension of the protruding part of the arched convex structure 24. Here, it is the maximum dimension of the arched convex structure 24 protruding downward, and the arch length is the arch span dimension, that is, the dimension in the extending direction (i.e., the length direction) of the arched convex structure 21. Such a setting can improve the structural strength and the anti - bending and anti - torsion stiffness at the structurally weak positions of the reinforcing plate 2 itself, thereby enhancing the structural reliability of the reinforcing plate 2. It can also make the reinforcing plate 2 have different strengths and sizes of closed cavities formed with the rear cross - beam 1 at different positions through a plurality of arched convex structures 24 with different height - width ratios at different positions, so as to generate different vibration frequencies for the vibration received by the rear cross - beam 1, and thus achieve the local frequency avoidance effect of the sunroof frame 100.
[0053] According to some alternative embodiments of the present invention, the length of the reinforcing plate 2 is L1, and the length of the rear cross - beam 1 is L2. Among them, L1 and L2 satisfy the relationship L1≥2 / 3*L2. Such an arrangement can make the reinforcing plate 2 cover most of the length space of the rear cross - beam 1 in the length direction, so as to effectively cover the structurally weak area at the middle position of the rear cross - beam 1, thereby improving the structural strength of the structurally weak position on the rear cross - beam 1.
[0054] Optionally, the width of the reinforcing plate 2 is W1, and the width of the rear cross - beam 1 is W2. Among them, W1 and W2 satisfy the relationship W1≥2 / 3*W2. Such an arrangement can make the reinforcing plate 2 cover most of the width space of the rear cross - beam 1 in the width direction, so as to effectively cover the structurally weak area at the middle position of the rear cross - beam 1, thereby improving the structural strength of the structurally weak position on the rear cross - beam 1.
[0055] According to some alternative embodiments of the present invention, as shown in Figure 3 the reinforcing plate 2 is formed with a recessed portion 25 and a protruding portion 26 on at least one side in the front - rear direction, and the recessed portion 25 and the protruding portion 26 are alternately arranged in the left - right direction.
[0056] Among them, compared with the flat shape, the alternately arranged recessed portion 25 and protruding portion 26 in the left - right direction can effectively increase the spatial mode of the reinforcing plate 2 on the premise of limited length dimensions, thereby improving the anti - bending and anti - torsion stiffness of the reinforcing plate 2, and further enhancing the structural reliability of the reinforcing plate 2.
[0057] Furthermore, as shown in Figure 1As shown, the front crossbeam 101 and the rear crossbeam 1 are arranged at intervals in the front-rear direction. The front crossbeam 101 and the rear crossbeam 1 are respectively connected between two longitudinal beams 102 arranged at intervals in the left-right direction, and they jointly form a closed frame structure. In this way, a closed force transmission structure can be formed, thereby improving the overall structural reliability.
[0058] The vehicle according to the second aspect embodiment of the present invention includes the sunroof frame 100 of the above embodiment. In this way, the vehicle with the sunroof frame 100 can enhance the structural strength of the sunroof frame 100, and can also reduce the vibration energy of the rear crossbeam 1 on the sunroof frame 100, thereby improving the structural reliability and ride comfort of the vehicle, and further enhancing the market competitiveness of the whole vehicle.
