Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a luggage rack, a roof assembly, and a method for installing the same. Background Technology

[0002] Because the vehicle features a panoramic sunroof, the sunroof glass requires a significant installation area on the roof, limiting the space available for roof racks. The simultaneous presence of a roof rack and panoramic sunroof can easily cause interference, making integration difficult. In related technologies, the sunroof glass is glued to the roof panel, and the roof rack is also glued to the sunroof glass. However, the stability of the roof rack after installation is poor, and it is prone to detaching from the roof panel. Furthermore, the load-bearing capacity of the roof rack is easily transferred directly to the sunroof glass, increasing the risk of breakage. Summary of the Invention

[0003] Therefore, it is necessary to provide a roof rack, a roof assembly, and an installation method thereof, which can easily integrate the roof rack and the panoramic sunroof, improve the stability of the roof rack and the sunroof glass after installation, and reduce the risk of damage to the sunroof glass and the roof rack falling off.

[0004] In a first aspect, embodiments of this application provide a luggage rack, including:

[0005] A first beam extends in a first direction, and a mounting groove is provided on one side of the first beam in a second direction. The mounting groove is used to accommodate the side of the skylight glass, and the groove wall of the mounting groove is spaced apart from the skylight glass.

[0006] Fasteners, a portion of which are inserted through the roof sheet metal and extend into the vehicle compartment, are used to fix the first beam to the roof sheet metal in a third direction, wherein the first direction, the second direction, and the third direction intersect each other.

[0007] In one embodiment, a first sealing member is further included. The first sealing member is disposed in the mounting groove. One side of the first sealing member in the second direction abuts against the bottom wall of the mounting groove. The other side of the first sealing member in the second direction has a snap-fit ​​groove for insertion with one end of the canopy glass in the second direction.

[0008] In one embodiment, a second seal is also included, wherein one end of the second seal abuts against the side wall of the first beam and the other end abuts against the side wall of the roof sheet metal in the second direction.

[0009] In one embodiment, the first beam has a limiting groove on the side facing away from the canopy glass in the second direction, and at least a portion of the second seal is installed in the limiting groove.

[0010] In one embodiment, the limiting groove includes a first groove and a second groove that are connected, the first groove and the second groove being disposed sequentially away from the panoramic glass in the second direction; the second sealing member includes a limiting portion and an abutting portion connected in the second direction, the limiting portion being located in the first groove, the maximum dimension of the limiting portion in the third direction being greater than the maximum dimension of the second groove in the third direction, and the abutting portion protruding from the second groove and used to abut against the side wall of the roof sheet metal.

[0011] In one embodiment, the abutment portion is tilted toward the side away from the skylight glass in the second direction from the skylight glass toward the bottom wall of the limiting groove.

[0012] In one embodiment, the first beam body has a cavity inside and also includes a reinforcing rib located in the cavity. In the direction along the second direction from the bottom wall of the mounting groove to the skylight glass, the reinforcing rib is inclined toward the side away from the skylight glass.

[0013] In one embodiment, the thickness of the sidewall of the first beam at the end near the roof panel in the third direction is greater than the thickness of the sidewalls of the other parts of the first beam.

[0014] In one embodiment, a third seal is further included, which extends in the third direction and is fitted around the periphery of the fastener. The third seal abuts against the first beam on one side in the third direction and abuts against the roof sheet metal on the opposite side in the third direction.

[0015] In one embodiment, the bottom surface of the mounting groove is perpendicular to the two opposite sides of the mounting groove.

[0016] In one embodiment, the fastener includes a stud and a locking nut, the stud extending upward on the third side, the stud being connected to the first beam, the stud penetrating the roof sheet metal and extending into the passenger compartment, the locking nut being sleeved on the stud and located inside the passenger compartment, and the locking nut abutting against the opposite side wall of the roof sheet metal.

[0017] Secondly, this application provides a roof assembly, including a panoramic glass and a luggage rack as described in any one of the first aspects, wherein there are two first beams, which are spaced apart in a second direction; the two first beams are corresponding to the two sides of the panoramic glass in the second direction; the sides of the panoramic glass in the second direction are inserted into the mounting groove through the first sealing member.

[0018] Thirdly, this application provides a method for installing a roof assembly, used to install the roof assembly described in the second aspect, the method comprising the following steps:

[0019] The two sides of the canopy glass in the second direction are inserted into the mounting groove of the first beam one by one through the first sealing member to be fixedly connected to the luggage rack assembly.

[0020] An adhesive layer is provided between the panoramic glass and the roof sheet metal part on the opposite sidewalls along the third direction;

[0021] The roof panel is fixedly connected to the luggage rack using fasteners.

[0022] The aforementioned roof rack features a mounting groove on one side of the first beam in the second direction, which accommodates the side of the panoramic sunroof, facilitating integration of the roof rack and panoramic sunroof. Furthermore, fasteners penetrate the roof panel and extend into the passenger compartment, securing the integrated panoramic sunroof and roof rack to the roof panel. Compared to related technologies where the sunroof, roof rack, and roof panel are bonded together, this improves the stability of the roof rack after installation and reduces the risk of detachment. Simultaneously, because the groove wall is spaced apart from the sunroof, stress on the roof rack is directly transferred to the roof panel, not the sunroof, further reducing the risk of sunroof breakage.

[0028] 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.

[0029] See Figure 1 and Figure 3 As shown, an embodiment of this application provides a luggage rack including a first beam 1 and fasteners 2. The first beam 1 extends in a first direction and is used to connect with the roof sheet metal 7. To avoid interference between the first beam 1 and the panoramic sunroof 6 during installation, a mounting groove 11 is provided on one side of the first beam 1 in a second direction. The mounting groove 11 extends in the first direction and is used to accommodate the side of the panoramic sunroof 6. The groove wall of the mounting groove 11 is spaced apart from the panoramic sunroof 6, meaning that the groove wall of the mounting groove 11 does not contact the side walls and outer peripheral walls of the panoramic sunroof 6 in the thickness direction. By accommodating the side of the panoramic sunroof 6 through the mounting groove 11, the luggage rack and panoramic sunroof are integrated. Fastener 2 extends through the roof sheet metal 7 and into the passenger compartment. It securely connects the first beam 1 to the roof sheet metal 7 in a third-order direction. Compared to related technologies where the sunroof glass, roof rack, and roof sheet metal are fixed by adhesive bonding, this improves the stability of the roof rack and sunroof glass 6 after installation, reducing the risk of the roof rack falling off. Furthermore, because the mounting groove 11 is spaced apart from the sunroof glass 6, the sunroof glass 6 does not contact the roof rack. When the roof rack is subjected to force, the force is directly transferred to the roof sheet metal, not to the sunroof glass 6, thus reducing the risk of damage to the sunroof glass 6.

[0030] It should be noted that the first direction is the length direction of the first beam 1 (X-axis direction in the figure). The length direction of the first beam 1 is the same as the length direction of the vehicle body. The first beam 1 is the longitudinal beam part of the roof rack assembly, which is used for installation and positioning with the roof sheet metal part 7. The second direction is the width direction of the first beam 1 (Y-axis direction in the figure). The third direction is the height direction of the first beam 1 (Z-axis direction in the figure). The first direction, the second direction and the third direction intersect each other.

[0031] Furthermore, since the first beam 1 is generally made of aluminum alloy through a metal extrusion process, after the side of the skylight glass 6 is accommodated in the mounting groove 11, if the side wall of the skylight glass 6 directly abuts against the side wall of the mounting groove 11, the skylight glass 6 is easily damaged due to vibration during vehicle operation. In this application, the groove wall of the mounting groove 11 is spaced apart from the skylight glass 6. To prevent dust, rainwater, and other impurities from the external environment from entering the mounting groove 11 through the gap between the skylight glass 6 and the groove wall of the mounting groove 11, causing contact wear or breakage between the skylight glass 6 and the side wall of the mounting groove 11, thus reducing the stability of the connection between the first beam 1 and the skylight glass 6. In this application, if... Figure 1 and Figure 2 As shown, in order to improve the stability of the connection between the skylight glass 6 and the first beam 1, and at the same time reduce the risk of damage to the skylight glass 6, in one embodiment, the luggage rack further includes a first seal 3. The first seal 3 extends in a first direction and is installed in the mounting groove 11. One side of the first seal 3 in a second direction abuts against the bottom wall of the mounting groove 11, and the other side of the first seal 3 in the opposite direction in the second direction has a snap-fit ​​groove 31, and one end of the skylight glass 6 in the second direction is inserted into the snap-fit ​​groove 31.

[0032] It should be noted that the first seal 3 and the mounting groove 11 are interference-fitted. The first beam 1 presses and fixes the first seal 3 within the mounting groove 11, preventing the first seal 3 from falling out of the mounting groove 11. Simultaneously, the dimension of the snap-fit ​​groove 31 in the third direction is slightly smaller than the thickness of the panoramic glass 6, so as to press, fix, and seal the portion of the panoramic glass 6 located within the snap-fit ​​groove 31. This prevents dust, rainwater, and other impurities from the external environment from entering the snap-fit ​​groove 31, improving the stability of the connection between the first beam 1 and the panoramic glass 6. Furthermore, due to the presence of the first seal 3, the panoramic glass 6 is flexibly connected to the first beam 1 through the first seal 3, which can buffer vibrations during vehicle operation and reduce the risk of collision damage between the panoramic glass 6 and the first beam 1.

[0033] Furthermore, to simplify the structure of the mounting groove 11 and facilitate its processing, while ensuring uniform stress distribution on the portion of the canopy glass 6 within the mounting groove 11 via the first sealing member 3, the bottom surface of the mounting groove 11 is perpendicular to its two opposing sides in the third direction, forming a U-shaped structure. For example... Figure 1 and Figure 2As shown, the two side walls of the mounting groove 11, which are spaced apart in the third direction, are parallel to each other. After the first beam 1 and the skylight glass 6 are installed, the two side walls of the skylight glass 6 in the thickness direction are parallel to the two side walls of the mounting groove 11, which can avoid local stress concentration between the skylight glass 6 and the side walls of the mounting groove 11, and reduce the risk of breakage of the skylight glass 6.

[0034] Furthermore, since the first seal 3 is installed on the outside of the vehicle body, it needs to be exposed to a complex outdoor environment for a long time, enduring the erosion of multiple environmental factors such as sunlight, rain, and ultraviolet radiation. To improve the structural stability of the first seal 3, it must possess good weather resistance, anti-aging properties, and waterproof sealing performance. In one embodiment, the first seal 3 is made of ethylene propylene diene monomer (EPDM) rubber or thermoplastic vulcanizate (TPV) rubber. This can prevent the first seal 3 from becoming brittle, cracking, or softening under extreme environments such as high temperature, low temperature, and alternating hot and humid conditions. At the same time, it avoids performance degradation caused by ultraviolet radiation and oxidation, thereby maintaining long-term elasticity and structural integrity, and ensuring a good waterproof sealing effect.

[0035] Furthermore, such as Figure 1 As shown, to avoid interference between the roof rack and the roof sheet metal 7 during installation, a gap exists between the first beam 1 and the side wall of the roof sheet metal 7 in the second direction. This gap not only affects the overall aesthetics of the vehicle, but also allows dust, grit, and other impurities from the external environment to easily enter and become lodged between the first beam 1 and the side wall of the roof sheet metal 7. This leads to wear on both the first beam 1 and the roof sheet metal 7, and generates abnormal noises during vehicle bumps or vibrations, affecting the driving experience. In this application, as... Figure 1 As shown, the roof rack also includes a second seal 4. In the second direction, one end of the second seal 4 abuts against the side wall of the first beam 1, and the other end abuts against the side wall of the roof sheet metal 7. The first seal 3 is used to cover the gap between the first beam 1 and the side wall of the roof sheet metal 7, improving the overall aesthetics of the vehicle and preventing impurities from the external environment from entering the gap, reducing the risk of wear on the first beam 1 and the roof sheet metal 7, and avoiding abnormal noise, thus improving the driving experience of the vehicle.

[0036] It should be noted that, in this application, if Figure 1As shown, the roof sheet metal 7 includes an interior sheet metal 71 and a side sheet metal 72. Specifically, the first beam 1 has a gap between itself and the side wall of the roof sheet metal 7 in the second direction; the second seal 4 is located between the side sheet metal 72 and the first beam 1. In the third direction, the side sheet metal 72 and the interior sheet metal 71 are partially stacked to support the first beam 1 and increase its stability after installation.

[0037] Furthermore, such as Figure 2 As shown, to facilitate the installation of the second seal 4 and prevent it from detaching from the gap between the roof panel 7 and the first beam 1, in one embodiment, a limiting groove 12 is formed on the side of the first beam 1 facing away from the panoramic glass 6 in the second direction, and at least a portion of the second seal 4 is embedded in the limiting groove 12. Both ends of the second seal 4 abut against the sidewalls of the limiting groove 12 and the roof panel 7 respectively, limiting the second seal 4 in the second direction. Simultaneously, since the opening of the limiting groove 12 faces the roof panel 7, the limiting groove 12 also limits the second seal 4 in the third direction, thereby preventing the second seal 4 from detaching.

[0038] It should be noted that, since the second seal 4 is exposed to the outdoor environment, in one embodiment, the second seal 4 is made of TPV material to improve its structural stability. Furthermore, to improve the production efficiency of the second seal 4, it is manufactured using an extrusion process. In some other embodiments, to reduce the impact of different temperatures in the outdoor environment on the performance of the second seal 4 and to improve its structural stability during installation and use, the second seal 4 also includes glass fiber. Glass fiber has the characteristics of high strength, high modulus, and low coefficient of thermal expansion; when uniformly dispersed in the second seal 4 in an appropriate proportion, it can improve the structural stability of the second seal 4.

[0039] Furthermore, such as Figure 2As shown, to prevent the second seal 4 from detaching after being installed in the limiting groove 12, and to improve the stability of the installation of the second seal 4 and the limiting groove 12, in one embodiment, the limiting groove 12 includes a first groove 121 and a second groove 122 connected in a second direction. The first groove 121 and the second groove 122 are sequentially disposed away from the sunroof glass 6 in a second direction. The maximum dimension of the first groove 121 in a third direction is greater than the maximum dimension of the second groove 122 in a third direction. The limiting groove 12 is generally T-shaped. The second seal 4 includes a limiting portion 41 and an abutting portion 42 sequentially connected in a second direction. The limiting portion 41 is located inside the first groove 121. The maximum dimension of the limiting portion 41 in a third direction is greater than the maximum dimension of the second groove 122 in a third direction. At least a portion of the abutting portion 42 extends outside the second groove 122 and is used to abut against the side wall of the roof sheet metal 7. When the second seal 4 is installed in the limiting groove 12, it has an inverted structure, which can prevent the second seal 4 from detaching from the limiting groove 12 in both the second and third directions. It should be noted that both the second seal 4 and the limiting groove 12 extend in the first direction. When the second seal 4 and the limiting groove 12 are installed, the limiting part 41 can be inserted into the limiting groove 12 along the first direction.

[0040] Furthermore, such as Figure 2 As shown, to facilitate the insertion of the limiting part 41 into the limiting groove 12 and improve assembly efficiency, in one embodiment, the limiting part 41 includes a main body segment 411 and a deformable segment 412. The main body segment 411 extends along a second direction, with one end connected to the abutment portion in the second direction, and the other end abutting against the bottom wall of the first groove 121 in the opposite direction. The deformable segment 412 is arranged around the outer peripheral wall of the main body segment 411 and is used to abut against the side wall of the first groove 121. When the limiting part 41 is inserted into the limiting groove 12, the deformable segment 412 can tilt and elastically deform close to the main body segment 411, facilitating the rapid insertion of the limiting part 41 into the limiting groove 12. After the limiting part 41 is fully inserted into the limiting groove 12, the deformable segment 412 rebounds and abuts against the inner wall of the limiting groove 12, thereby fixing the second seal 4 within the limiting groove 12.

[0041] Furthermore, in order to increase the contact area between the abutment portion 42 and the side wall of the roof sheet metal 7, and to reduce the resistance of the abutment portion 42 during the installation of the first beam 1 and the roof sheet metal 7, thus facilitating the assembly of the first beam 1 and the roof sheet metal 7, in some embodiments, the abutment portion 42 is inclined toward the side away from the sunroof glass 6 in the direction along the second direction from the sunroof glass 6 to the bottom wall of the limiting groove 12. (See also...) Figure 1 and Figure 2Specifically, in one embodiment, in the direction along the second direction from the sunroof glass 6 to the bottom wall of the limiting groove 12, the abutment portion 42 is inclined towards the side away from the sunroof glass 6. This increases the contact area between the abutment portion 42 and the side wall of the roof sheet metal 7, reducing the resistance of the abutment portion 42 during the installation of the first beam 1 and the roof sheet metal 7, and making it easier to conceal the gap between the roof sheet metal 7 and the first beam 1 in the second direction. Simultaneously, due to the inclined arrangement of the abutment portion 42, after it abuts against the roof sheet metal 7, force analysis shows that the force exerted by the abutment portion 42 on the first beam 1 points from the first beam 1 towards the roof sheet metal 7, increasing the pressure between the first beam 1 and the roof sheet metal 7 and improving the stability of the connection between the first beam 1 and the roof sheet metal 7.

[0042] Furthermore, such as Figure 1 As shown, to simplify the structure of fastener 2, in one embodiment, fastener 2 includes a stud 21 and a locking nut 22. The stud 21 extends upward in a third direction and is connected to the first beam 1. The stud 21 passes through the roof sheet metal 7 and extends into the passenger compartment. The locking nut 22 is sleeved on the stud 21 and located inside the passenger compartment, abutting against the opposite side wall of the roof sheet metal 7. In related technologies, to fix the roof rack to the roof sheet metal 7, a die-cast aluminum seat is usually provided between the first beam 1 and the roof sheet metal 7. The roof rack is first fixed to the die-cast aluminum seat, and then the first beam 1 and the roof sheet metal 7 are connected by fastener 2. In this application, to reduce the overall number of parts of the roof rack and further reduce the production cost of the roof rack, the thickness of the side wall of the first beam 1 near the roof sheet metal 7 in a third direction is greater than the thickness of the side walls of other parts of the first beam 1. Specifically, as shown... Figure 1 and Figure 2 As shown, the first beam 1 includes a mounting part 15 and a main body 16. The mounting part 15 and the main body 16 are arranged sequentially away from the roof sheet metal part 7 in a third-dimensional direction. The mounting part 15 and the main body 16 together form a mounting groove 11. The mounting part 15 has a threaded hole for threaded connection with the stud 21. The wall thickness of the mounting part 15 is greater than the wall thickness of the main body 16. It should be noted that the increased thickness of the mounting part 15 not only facilitates the threaded connection with the stud 21 and reduces the number of parts in the luggage rack, but also, since the load on the luggage rack is transmitted from top to bottom, the increased thickness of the mounting part 15 helps to improve the overall support strength of the luggage rack, allowing it to bear heavier luggage and increasing the structural strength of the luggage rack.

[0043] Furthermore, such as Figure 1As shown, when the first beam 1 is fixedly connected to the roof sheet metal 7 using fasteners 2, mounting holes need to be made on the roof sheet metal 7 for the studs 21 of the fasteners 2 to pass through. Since one end of the stud 21 is located outside the vehicle and the other end is located inside the vehicle, the mounting holes need to be sealed to prevent water and impurities from the external environment from entering the vehicle through the mounting holes. In this application, as... Figure 1 As shown, the luggage rack also includes a third seal 5, which extends in a third direction and is fitted around the fastener 2. One side of the third seal 5 abuts against the first beam 1 in the third-direction upward direction, and the other side abuts against the roof panel 7 in the third-direction upward direction. The third seal 5 seals the mounting holes to prevent water from the external environment and the roof from entering the passenger compartment. The third seal 5 is generally made of waterproof foam, which can be EPDM material, capable of preventing water penetration while also possessing a certain degree of elasticity. Therefore, the third seal 5 can also buffer the vibration transmitted from the luggage rack to the roof panel 7 when luggage is placed or during vehicle operation, preventing collisions or wear between the first beam 1 and the opposite sidewalls of the roof panel 7.

[0044] Based on the same concept, this application also provides a roof assembly, including a panoramic glass, multiple second beams, and a luggage rack as described above. There are two first beams 1, spaced apart in a second direction. The two first beams 1 correspond one-to-one with the two sides of the panoramic glass 6 in the second direction. The sides of the panoramic glass 6 in the second direction are inserted into the mounting groove 11 via a first sealing member 3. That is, the two sides of the panoramic glass 6 in the second direction are flexibly connected to the first beams 1 in a corresponding manner. The second beams (not shown in the figure) extend in the second direction, with multiple second beams spaced apart in the first direction. The two ends of each second beam in the second direction are connected one-to-one to the two first beams 1.

[0045] It should be noted that the first beam 1 is the longitudinal beam of the luggage rack, and the second beam is the transverse beam of the luggage rack assembly. The two first beams 1 are spaced apart in the second direction, and multiple second beams are spaced apart in the first direction to enclose and form a storage space for luggage, providing support for the outer circumference and / or bottom of the luggage. During placement, the luggage comes into contact with the first beam 1 and / or the second beam, thereby transferring the load to the roof sheet metal 7.

[0046] like Figure 1 and Figure 2As shown, to facilitate the rapid installation and positioning of the first beam 1 and the second beam in the luggage rack, in this application, the first beam 1 has positioning grooves 17 for connecting with the second beam on both side walls spaced apart in the second direction. Specifically, in one embodiment, there are two positioning grooves 17, and the two side walls of the first beam 1 spaced apart in the second direction are recessed inward to form the positioning grooves 17. The end of the second beam in the second direction (i.e., the length direction of the second beam) has protrusions corresponding to the positioning grooves 17, and the two protrusions form a claw-like structure to achieve the connection and positioning between the second beam and the first beam 1.

[0047] like Figure 1 As shown, in some embodiments, to reduce the overall weight of the luggage rack, the first beam 1 and the second beam are typically manufactured using a metal extrusion process. The first beam 1 has an internal cavity 13 to reduce the weight of the luggage rack assembly. During the installation of the first beam 1 and the second beam, the second beam compresses the two side walls of the first beam 1 in the second direction. Simultaneously, when luggage is placed on the luggage rack, a load is applied to the side wall of the first beam 1 near the canopy glass 6 in the second direction. Figure 1 (The direction of the dashed arrow in the diagram). In one embodiment, the first beam 1 further includes a reinforcing rib 14 located within the cavity 13. Along the second direction from the bottom wall of the mounting groove 11 towards the canopy glass 6, the reinforcing rib 14 is inclined towards the side away from the canopy glass 6, which enhances the supporting strength of the first beam 1 and prevents deformation caused by the compression of the second beam. Simultaneously, when the luggage rack carries heavy objects, the load can be distributed to the bottom of the first beam 1 through the reinforcing rib 14, thereby improving the load-bearing capacity and structural stability of the luggage rack.

[0048] Based on the same concept, this application also provides a method for installing a roof assembly, which includes the following steps:

[0049] The two sides of the panoramic glass 6 in the second direction are inserted into the mounting grooves 11 of the first beam 1 one by one through the first sealing member 3, so that the panoramic glass 6 is fixedly connected to the roof rack; an adhesive layer is provided between the panoramic glass 6 and the opposite sidewalls of the roof sheet 7 in the third direction; the roof sheet 7 is fixedly connected to the roof rack by fasteners.

[0050] Specifically, in this application, such as Figure 1As shown, the first sealing element 3 is located in the mounting groove 11. The side edges of the panoramic sunroof 6 in the second direction are inserted one-to-one into the snap-fit ​​grooves 31 of the first sealing element 3 located in the first beam 1, limiting the position of the panoramic sunroof 6 in the second and third directions, thereby fixing the panoramic sunroof 6 to the roof rack. After the panoramic sunroof 6 is integrated with the roof rack, the whole assembly is assembled with the roof sheet metal 7 to achieve the integration of the roof rack and panoramic sunroof. This allows for integrated supply, reducing the installation difficulty of the roof rack and panoramic sunroof during vehicle assembly by the OEM, and improving the overall vehicle production efficiency. To prevent relative movement between the panoramic sunroof 6 and the roof sheet metal 7, an adhesive layer 8 is provided between the opposite side walls of the panoramic sunroof 6 and the roof sheet metal 7 along the third direction. The adhesive layer 8 can be made of glass glue, which, after curing, can bond and fix the panoramic sunroof 6 to the roof sheet metal 7. Subsequently, the roof rack and the roof sheet metal 7 are fixedly connected by fasteners 2. Specifically, the first beam 1 is fixedly connected to the roof sheet metal 7 by fasteners 2, thereby realizing the simultaneous fixed connection of the sunroof glass 6 and the roof rack to the roof sheet metal 7. Compared with related technologies where the sunroof glass and the roof rack are connected to the roof sheet metal separately, this greatly improves the installation efficiency between the sunroof glass 6 and the roof rack and the roof sheet metal 7.

[0051] 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.

[0052] 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.
