Fig. 1 is a top view of an embodiment of the present invention for a rear roof rail of a vehicle. As shown in fig. 1, in one or more embodiments, a rear roof rail 100 for a vehicle of the present invention includes a hardware mounting portion 10, a lap joint portion 20, and a gutter portion 30. The rear roof rail 100 is made of an aluminum alloy material through a high-pressure die casting process. Alternatively, other suitable metallic materials may be used for the rear roof rail 100. Alternatively, the overlap portion 20 or the gutter portion 30 may be omitted. The rear roof rail 100 of the present invention is an integral structure that includes only one plate-like member, rather than a rear roof rail assembly formed by two or more plates.

With continued reference to FIG. 1, in one or more embodiments, the rear roof rail 100 has a first surface 40. The first surface 40 is a continuous surface on one side of the plate-like rear roof rail 100 shown in fig. 1. The first surface 40 is adapted to face toward the outside of the vehicle in a state in which the rear roof rail 100 is mounted to the vehicle. The rear roof rail 100 also has a second surface 50 facing away from the first surface 40, which second surface 50 is adapted to face towards the passenger compartment of the vehicle in the state in which the rear roof rail 100 is mounted to the vehicle. The hardware mount 10 has a hardware mount area 10a on the first surface 40, where the hardware mount area 10a is adapted to place at least one predetermined hardware 700, the predetermined hardware 700 including, but not limited to, a 5g & wifi communication module, a GPS positioning module, a camera, and the like. The hardware mounting region 10a has opposed first and second longitudinal edges 11, 12, and first and second transverse edges 13, 14 extending between the first and second longitudinal edges 11, 12. The first longitudinal edge 11, the second longitudinal edge 12, the first transverse edge 13 and the second transverse edge 14 together enclose a generally rectangular area for mounting the predetermined hardware 700. In the mounted state on the vehicle, both the first lateral edge 13 and the second lateral edge 14 extend substantially in the lateral direction of the vehicle, and the first lateral edge 13 is close to the vehicle tail. Alternatively, the hardware mount area 10a may be configured in other suitable shapes.

Fig. 2 is a partial isometric view of the embodiment of the rear roof rail for a vehicle of the present invention shown in fig. 1. As shown in fig. 1 and 2, in one or more embodiments, a seal 15 is provided on the hardware mounting area 10a that extends continuously from the first longitudinal edge 11 to the second longitudinal edge 12. In one or more embodiments, the seal 15 is integrally formed on the rear roof rail 100 at the time of casting. The sealing portion 15 projects outwardly from the first surface 40 and has a top wall 151 (shown in fig. 4). The top wall 151 is adapted to form a sealed connection with the roof 600 of the vehicle so as to divide the hardware mounting area 10a into a dry mounting area 16 and a wet mounting area 17 spaced apart from each other. Alternatively, the sealing portion 15 may be configured in other suitable shapes. Alternatively, the sealing portion 15 may be provided on the hardware mounting region 10a by other suitable means, such as being fastened to the hardware mounting region 10a by a fastener using a rubber material. In one or more embodiments, a plurality of support protrusions 152 are provided on the top wall 151. The supporting protrusions 152 protrude upward from the outer wall surface of the top wall 151 so as to support the roof 600 of the vehicle. The top wall 151 formed by the high pressure die casting process may have an excessively large flatness error, resulting in a local roughness phenomenon. By the arrangement of the supporting protrusions 152, the top cover 600 directly abuts against the plurality of supporting protrusions 152, and the other positions of the top wall 151 where the supporting protrusions 152 are not provided are filled with glue to eliminate the influence of manufacturing deviation of the top wall 151. The gel includes, but is not limited to, a sealant, a glass gel, and the like.

With continued reference to fig. 1, in one or more embodiments, the seal 15 includes a first straight segment 153, a bent segment 154, and a second straight segment 155 that are connected in sequence. In one or more embodiments, the bending section 154 is configured in a generally arcuate shape and both ends of the bending section 154 are disposed on the first lateral edge 13 such that the wet mounting area 17 is enclosed by the inner side 1541 of the bending section 154 along with the first lateral edge 13; the dry mounting area 16 is enclosed by the outer side 1542 of the folded section 154 together with the second transverse edge 14, the first straight section 153 and the second straight section 155. Alternatively, the two ends of the bending section 154 may be disposed at other suitable locations. In one or more embodiments, the bent section 154 is connected at both ends to the first straight section 153 and the second straight section 155, respectively. Alternatively, both ends of the bending section 154 may also be disposed away from the first straight section 153 and the second straight section 155. In one or more embodiments, the first straight section 153 and the second straight section 155 extend along the first lateral edge 13 so as to enclose a dry mounting area 16 that is as large as possible. Alternatively, the first straight section 153 and the second straight section 155 may be arranged away from the first transverse edge 13, in which case the first straight section 153 and the second straight section 155 each enclose 1 wet installation area 17 with the outer side 1542 of the bent section 154 and the first transverse edge 13, respectively, and together with the wet installation area 17 enclosed by the inner side 1541 of the bent section 154 and the first transverse edge 13, together with a total of 3 wet installation areas 17, when both ends of the bent section 154 are still arranged on the first transverse edge 13. In one or more embodiments, the intermediate portion of the bending section 154 intersects the second lateral edge 14. As shown in fig. 1, the generally arcuate bend 154 extends centrally beyond the second transverse edge 14, dividing the dry mounting region 16 defined by the second transverse edge 14 along with the first straight segment 153, the second straight segment 155, and the outer side 1542 of the bend 154 into 2 dry mounting regions 16, namely a first dry mounting region 161 located to the left of the bend 154 and a second dry mounting region 162 located to the right of the bend 154. Alternatively, the intermediate portion of the bending section 154 may be omitted from intersecting the second transverse edge 14 such that the dry mounting region 16 is integral. In alternative embodiments, the seal 15 may also be configured in other suitable shapes extending continuously between the first longitudinal edge 11 and the second longitudinal edge 12, configuring the hardware mounting area with other suitable numbers of dry mounting areas and other suitable numbers of wet mounting areas.

With continued reference to fig. 1, in one or more embodiments, the seal 15 further includes a third straight section 156 extending along the second lateral edge 14. The third straight section 156 may be configured to be discontinuous, i.e., an interrupted notch 1561 is formed in the third straight section 156. By providing third straight section 156, top cover 600 has more connection area with sealing portion 15 so as to enhance the connection strength of top cover 600 with rear roof rail 100. Alternatively, the third straight section 156 may be omitted. In one or more embodiments, the notch 1561 may be used for positioning of the overcap 600. Alternatively, the notch 1561 may also be used for passing wiring harnesses. In one or more embodiments, the seal 15 further includes a fourth straight segment 157 extending along the first longitudinal edge 11 and/or the second longitudinal edge 12. By the arrangement of the fourth straight section 157, the top cover 600 and the sealing portion 15 have more connection areas so as to improve the connection strength of the top cover 600 and the rear roof rail 100. Alternatively, the fourth straight section 157 may be omitted.

It should be noted that the first straight section 153, the second straight section 155, the third straight section 156 and the fourth straight section 157 described above are substantially straight in shape, but may also be configured to be slightly curved depending on the shape of the first longitudinal edge 11, the second longitudinal edge 12, the first transverse edge 13 and the second transverse edge 14.

With continued reference to FIG. 1, in one or more embodiments, 1 service hole 163 is formed in each of the first and second dry mounting regions 161, 162. Each service hole 163 extends through the rear roof rail 100, and the body of the predetermined hardware 700 is adapted to be received within the service hole 163. The repair holes 163 are sized to fit the predetermined hardware 700 housed therein. In one or more embodiments, a reinforcing flange 1631 (shown in FIG. 7) is provided at the edge of the service hole 163. Reinforcing flange 1631 is integrally formed on rear roof rail 100 at the time of casting and extends from the edge of service hole 163 toward the side where second surface 50 is located so as not to encroach on the space of hardware mounting area 10 a. Alternatively, the service holes 163 in each dry mounting area 16 may be configured in other numbers greater than 1, such as 2, 3, etc. Alternatively, the provision of the repair holes 163 may be omitted, and the predetermined hardware 700 may be installed by forming a plurality of doghouse structures having closed bottom surfaces on the rear roof rail 100.

With continued reference to FIG. 2, in one or more embodiments, the inner side 1541 of the bending section 154 and the first lateral edge 13 define the wet-mount area 17. In the mounted state on the vehicle, the wet mounting area 17 is adapted to be brought into communication with the outside space of the vehicle. Predetermined hardware 700 having a strict signal transmission/reception angle, such as a camera 701, a laser radar or a V2X module 702 (i.e., vehicle to Everything, "X" may mean any object capable of communicating with a vehicle, through which the vehicle can "communicate" with the outside by the V2X module 702), etc., is suitably disposed in the wet installation area 17. In one or more embodiments, the bottom wall of the wet mounting area 17 has a sloping downward slope (shown in fig. 3) in the mounted state to the vehicle, the first lateral edge 13 being the lowest point of the wet mounting area 17, since the wet mounting area 17 is adapted to be in direct communication with the exterior space of the vehicle. Furthermore, in one or more embodiments, to meet the needs of a plurality of predetermined hardware 700 disposed in the wet mounting area 17, a plurality of predetermined hardware 700 is disposed along a mounting gradient. For example, a camera 701 and a V2X module 702 having good air tightness are provided in the wet mounting area 17, and the V2X module 702 is provided below the camera 701. In one or more embodiments, the camera 701 is disposed on the wet mount area 17 by a camera 701 holder (not shown in the drawings) so as to be configured to be higher than the V2X module 702. Alternatively, the camera 701 may be disposed in the wet mount area 17 by other suitable means. In one or more embodiments, as shown in FIG. 2, a doghouse 171 (i.e., a recess recessed from the first surface 40 toward the interior of the rear roof rail 100) is formed on the wet mounting area 17 of the rear roof rail 100. The V2X module 702 is disposed in the doghouse 171 so as to be disposed lower than the camera 701 so as not to interfere with the visual range of the camera 701. Alternatively, the V2X module 702 may be secured in the wet mount area 17 by other suitable means. In alternative embodiments, the installation gradient setup may also be eliminated.
