[0002] As users increasingly value vehicle functionality, roof racks have become a popular feature. These racks not only serve an aesthetic purpose but also provide support for luggage and heavy items.

[0003] In related technologies, in order to improve the smoothness of the roof rack lines and make the roof rack more coordinated with the vehicle body shape, the ends of the roof rack are generally bent.

[0004] However, as the cross-sectional height of the luggage rack increases, the difficulty of bending the ends of the luggage rack increases dramatically, which in turn limits the design of the cross-sectional height of the luggage rack. Utility Model Content

[0005] Therefore, it is necessary to address the problem in the related technology that as the cross-sectional height of the luggage rack increases, the difficulty of bending the ends of the luggage rack increases sharply, which leads to the limitation of the cross-sectional height design of the luggage rack. In this regard, a luggage rack and vehicle are provided.

[0006] On one hand, this application provides a luggage rack, which includes a first rod and a second rod stacked together. The end of the first rod is provided with a first contact surface, and the end of the second rod is provided with a second contact surface. The end of the first rod is bent toward the second rod, and the radius of curvature of the bent portion is a preset radius of curvature. The preset radius of curvature is configured to make the first contact surface and the second contact surface fit together.

[0007] The aforementioned luggage rack, through the stacking of the first and second rods, helps to reduce the cross-sectional height of each individual rod, thereby reducing the difficulty of bending the end of the first rod and allowing it to be bent at a preset radius of curvature. Furthermore, the arrangement of a first contact surface at the end of the first rod and a second contact surface at the end of the second rod helps to ensure a proper fit between the end of the first rod and the end of the second rod after bending, thus improving the overlap and conformity of the first and second rods and meeting the bending requirements of the overlapping structure.

[0010] In one embodiment, the main body is provided with a flange structure at the connection with the first support portion, the flange structure being used to cover the end of the mounting portion.

[0011] In one embodiment, there is an assembly gap between the mounting part and the first support part, and the value of the assembly gap is in the range of 0-1.5mm.

[0012] In one embodiment, the second rod includes a third side, a fourth side, a first connecting portion, and a second connecting portion that are connected to each other. The third side is parallel to the fourth side, and both the third side and the fourth side are perpendicular to the first connecting portion. The first connecting portion is parallel to the second connecting portion.

[0013] In one embodiment, the first rod and the second rod are configured to have different colors and / or materials.

[0014] In one embodiment, the luggage rack includes at least two locking structures spaced apart along the length of the second rod, the locking structures being used to lock and secure the first rod and the second rod.

[0015] In one embodiment, the locking structure includes a double-ended bolt, a locking base, and a first seal. The double-ended bolt is used to lock the first rod and the second rod. The locking base is used to be disposed between the second rod and the body sheet metal part. The first seal is disposed between the locking base and the body sheet metal part.

Detailed Implementation

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] Please see Figure 1 This application provides a luggage rack 10, which may include a first rod 100 and a second rod 200 stacked together.

[0032] Combination Figure 2 and Figure 3 As shown, where Figure 2 This is a schematic diagram of the end milling area of ​​the first rod 100 of the luggage rack 10 in one embodiment of this application. Figure 3 for Figure 2 The diagram shows the structure of the end of the first rod 100 of the luggage rack 10 after milling. The end of the first rod 100 is provided with a first contact surface 101.

[0033] Combination Figure 4 and Figure 5 As shown, where Figure 4 This is a schematic diagram of the end milling area of ​​the second rod 200 of the luggage rack 10 in one embodiment of this application. Figure 5 for Figure 4 The diagram shows the milled end of the second rod 200 of the luggage rack 10. The end of the second rod 200 is provided with a second contact surface 201.

[0034] Combination Figure 6 As shown, Figure 6 This is an assembly diagram of the first rod 100 and the second rod 200 of the luggage rack 10 in one embodiment of this application. The end of the first rod 100 is bent toward the second rod 200, and the radius of curvature of the bent portion is a preset radius of curvature. The preset radius of curvature is configured such that the first mating surface 101 and the second mating surface 201 fit together properly.

[0035] The aforementioned luggage rack 10, through the overlapping arrangement of the first rod 100 and the second rod 200, helps to reduce the cross-sectional height of each individual rod, thereby reducing the difficulty of bending the end of the first rod 100 and allowing the end of the first rod 100 to be bent with a preset radius of curvature. Furthermore, the arrangement of a first contact surface 101 at the end of the first rod 100 and a second contact surface 201 at the end of the second rod 200 helps to ensure a proper fit between the end of the first rod 100 and the end of the second rod 200 after bending, thus improving the overlap and conformity of the first rod 100 and the second rod 200 and meeting the bending requirements of the overlapping structure.

[0036] It should be noted that the aforementioned preset radius of curvature can be determined based on the actual bending degree of the end of the first member 100, and is not limited here, as long as it meets the requirement that the preset radius of curvature corresponding to the bending degree is configured to ensure that the first mating surface 101 and the second mating surface 201 fit together properly. Of course, it is understandable that the shapes of the first mating surface 101 and the second mating surface 201 can be adapted and designed accordingly based on different preset radii of curvature.

[0037] It is worth noting that the luggage rack 10 described in this application, through the overlapping arrangement of the first rod 100 and the second rod 200, allows for flexibility in the design process. This means that only the end of the first rod 100 can be bent, with the first mating surface 101 and the second mating surface 201 fitting together. Alternatively, the end of the first rod 100 can be bent at a larger angle, while the end of the second rod 200 is bent at a smaller angle, with the first mating surface 101 and the second mating surface 201 fitting together. In this way, both methods ensure that the end of the second rod 200 does not need to be bent or is bent at a smaller angle, thus ensuring the structural strength of the second rod 200 while meeting the bending requirements of the overlapping structure. Furthermore, the second rod 200, as a contact element connecting to the vehicle body, enhances the connection strength of the luggage rack 10 on the top of the vehicle body.

[0038] Please refer to the previous document. Figure 1 In some embodiments, the luggage rack 10 includes at least two locking structures 300, which are spaced apart along the length of the second rod 200. The locking structures 300 are used to lock and secure the first rod 100 and the second rod 200, thus ensuring the connection stability between the first rod 100 and the second rod 200. Simultaneously, this facilitates the detachable configuration of the first rod 100 and the second rod 200, improving the ease of component maintenance.

[0039] Optionally, the aforementioned locking structure 300 may be implemented as a bolt or locking pin, etc.

[0040] Please see Figure 7 In some embodiments, the locking structure 300 may include a double-ended bolt 310, a locking base 320 and a first seal 330. The double-ended bolt 310 is used to lock the first rod 100 and the second rod 200. The locking base 320 is used to be disposed between the second rod 200 and the body sheet metal part 20. The first seal 330 is disposed between the locking base 320 and the body sheet metal part 20.

[0041] Specifically, one end of the double-ended bolt 310 is used to lock the first rod 100 and the second rod 200, and the other end is used to lock the second rod 200 onto the body sheet metal part 20, resulting in a simple and reliable structure. The locking base 320 is used to fill the gap between the second rod 200 and the body sheet metal part 20, ensuring the force transmission of the double-ended bolt 310 and improving the locking effect of the double-ended bolt 310. The first sealing element 330 is used to improve the sealing performance, noise reduction, and structural protection between the locking base 320 and the body sheet metal part 20.

[0042] Optionally, please refer to Figure 7 In some embodiments, the double-ended bolt 310 may include a double-ended stud 311 and a rivet nut 312. The rivet nut 312 is used to pass through and clamp the first rod 100 and the second rod 200. One end of the double-ended stud 311 is threaded to the rivet nut 312, and the other end is used to first thread to the locking base 320 and then lock it to the body sheet metal part 20. This ensures the connection stability between the first rod 100 and the second rod 200, as well as the connection stability of the luggage rack 10 on the body sheet metal part 20.

[0043] Optionally, the aforementioned first seal 330 may be implemented as a sealing ring, etc.

[0044] Alternatively, please continue reading Figure 7 In some embodiments, the luggage rack 10 may also include a second seal 400 disposed between the second rod 200 and the body sheet metal 20, thereby improving the sealing performance, noise reduction and structural protection between the second rod 200 and the surface of the body sheet metal 20.

[0045] Optionally, the aforementioned second seal 400 may be implemented as, but is not limited to, a foam strip, etc.

[0046] Please see Figure 8 In some embodiments, the first rod 100 may include an integrally formed main body 110 and a first support 120, and the second rod 200 may include an integrally formed mounting portion 210 and a second support portion 220, combined with... Figure 10As shown, the mounting part 210 is provided with a receiving groove 2101, the first support part 120 is limited to the receiving groove 2101, and the first support part 120 and the second support part 220 abut against each other.

[0047] Specifically, the main body 110, as the uppermost structure of the luggage rack 10, not only serves an aesthetic purpose within the vehicle but also directly contacts and supports luggage and heavy items. The mounting section 210, with its receiving groove 2101, enhances the assembly positioning of the first member 100 and also limits its width in the luggage rack 10, improving the assembly stability between the first member 100 and the second member 200. The mutual abutment between the first support section 120 and the second support section 220 helps ensure the overlap and fit between the first member 100 and the second member 200.

[0048] Please see Figure 9 In some embodiments, the first support portion 120 may include a first side portion 121, a second side portion 122, and a bottom portion 123 connected to each other. The first side portion 121 and the second side portion 122 are parallel and both are perpendicular to the bottom portion 123. This allows the structures of the first side portion 121 and the second side portion 122 to be arranged at the cross-sectional height of the luggage rack 10 perpendicular to the bottom portion 123. This ensures that when the end of the first rod 100 is subjected to the aforementioned bending operation in the cross-sectional height direction of the luggage rack 10, the structures of the first side portion 121 and the second side portion 122 can still remain arranged in the cross-sectional height direction of the luggage rack 10, thereby improving the structural strength of the first side portion 121 and the second side portion 122 and increasing the load-bearing capacity for luggage and heavy objects.

[0049] More specifically, the direction of force exerted by luggage and heavy objects on the luggage rack 10 is generally along the cross-sectional height direction of the luggage rack 10. Therefore, setting the first side 121 and the second side 122 to be perpendicular to the bottom 123 helps to reduce the adverse effect of the vertical pressure of luggage and heavy objects on the first side 121 and the second side 122 being dispersed to both sides, thereby improving the load-bearing capacity of the first side 121 and the second side 122.

[0050] Please see Figure 10 In some embodiments, the second rod 200 may include a third side 211, a fourth side 212, a first connecting part 213 and a second connecting part 214 that are connected to each other. The third side 211 and the fourth side 212 are parallel, and both the third side 211 and the fourth side 212 are perpendicular to the first connecting part 213. The first connecting part 213 and the second connecting part 214 are parallel.

[0051] It should be noted that the second connecting portion 214 is used to directly contact and fix the body sheet metal part 20. The first connecting portion 213 is used to directly contact and support the first rod 100. The third side portion 211, the fourth side portion 212, the first connecting portion 213, and the second connecting portion 214 can be mutually enclosed to form the aforementioned second support portion 220 with a rectangular cross-sectional shape. The second support portion 220 can be, but is not limited to, hollow, which helps to ensure structural strength while reducing the weight of the parts and improving lightweighting. It is worth noting that part of the structure of the third side portion 211 and the fourth side portion 212 can be protruding relative to the first connecting portion 213. In this way, the two protruding portions on both sides and the first connecting portion 213 can be mutually enclosed to form the aforementioned receiving groove 2101, which is used to assemble and limit the first rod 100.

[0052] Optionally, the aforementioned first mating surface 101 and second mating surface 201 may be manufactured by, but not limited to, milling operations.

[0053] It is also worth noting that you should refer to Figure 11 According to this embodiment of the application, when milling the second mating surface 201 at the end of the second rod 200, only the third side 211, the fourth side 212, and the first connecting portion 213 can be milled, while retaining the structure of the second connecting portion 214. Figure 11 The first connecting portion 213 is milled, while the second connecting portion 214 is retained. This helps to increase the length of the second connecting portion 214, thereby increasing the contact area between the second rod 200 and the body sheet metal, and thus improving the connection stability between the roof rack 10 and the body.

[0054] Furthermore, the arrangement that the first side 121 and the second side 122 are both perpendicular to the bottom 123, and the third side 211 and the fourth side 212 are both perpendicular to the first connecting part 213, helps to ensure that the width of the first rod 100 and the second rod 200 remains unchanged regardless of the milling depth of the first contact surface 101 and the second contact surface 201 at the cross-sectional height of the luggage rack 10. Thus, only the curvature shape of the first contact surface 101 and the second contact surface 201 at the cross-sectional height needs to be adapted, avoiding the problem that the first rod 100 and the second rod 200 cannot be adapted and overlapped due to the inconsistency in width caused by milling. Therefore, by having the first side portion 121 and the second side portion 122 both perpendicular to the bottom portion 123, and the third side portion 211 and the fourth side portion 212 both perpendicular to the first connecting portion 213, it helps to expand the degree of freedom in milling depth design. In other words, it increases the degree of freedom in bending the first rod 100 at its end.

[0055] Optionally, the aforementioned first side 121, second side 122, bottom 123, third side 211, fourth side 212, first connecting part 213, and second connecting part 214 can all be configured as plates extending along the length of the luggage rack 10. The main body 110 can be designed according to actual appearance or load-bearing area requirements, and is not limited here.

[0056] Please refer to the previous document. Figure 7 and Figure 9 In some embodiments, the main body 110 is provided with a flange structure 111 at the connection with the first support 120. The flange structure 111 is used to cover the end of the second rod 200, i.e. the mounting part 210, in terms of cross-sectional height. This avoids the problem of the end of the mounting part 210 being exposed at the connection with the first rod 100, which reduces the aesthetics. This helps to improve the structural integrity and aesthetics of the luggage rack 10.

[0057] Please continue reading. Figure 7 In some embodiments, there is an assembly gap d between the mounting part 210 and the first support part 120. The value of the assembly gap d is in the range of 0-1.5mm, which helps to improve the assembly tolerance and ease of assembly between the first support part 120 and the mounting part 210. For example, the aforementioned assembly gap d can be 0, 0.5mm, 1mm, or 1.5mm, etc.

[0058] In some instances, the first rod 100 and the second rod 200 can be configured with different colors and / or materials, giving the luggage rack 10 a layered appearance with different effects. This helps to improve the diversity and aesthetics of the luggage rack 10. For example, the first rod 100 and the second rod 200 can have a two-tone design, or the first rod 100 and the second rod 200 can each have a different material design, or even the first rod 100 and the second rod 200 can have both a two-tone design and different material designs.

[0059] According to another aspect of this application, this application also provides a vehicle that may include the aforementioned roof rack 10. Understandably, the roof rack 10 of this application may be configured as two racks, with the two racks 10 respectively arranged on both sides of the roof of the vehicle along the width direction and also arranged along the length direction of the vehicle.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
