Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicles, and specifically provides a rear roof cross beam for a vehicle and a vehicle. BACKGROUND

[0002] The rear roof cross beam of a vehicle (also referred to as a vehicle rear beam or a rear fixed cross beam) is an important component in the roof structure. The rear roof cross beam plays a role of structural reinforcement at the rear of the vehicle, and it connects and supports the rear of the vehicle body, such as the left side wall assembly, the right side wall assembly, and the rear door assembly, to increase the stiffness and load-carrying capacity of the rear of the vehicle body, and to improve the stability and safety of the vehicle. In particular, in the event of a collision or accident, the rear roof cross beam can bear part of the impact force to protect the vehicle occupants and the vehicle structure.

[0003] In the prior art, the hardware for transmitting and receiving signals is usually arranged in a shark fin-shaped roof antenna, or arranged in a spoiler on the rear door. However, with the continuous development of the intelligence of electric vehicles, there are more and more hardware for assisting driving and intelligent networking arranged on the vehicle, and more and more of these hardware tend to be arranged in the roof area for better information collection and information interaction. The roof structure in the prior art cannot meet the arrangement requirements of these hardware.

[0004] Therefore, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0005] In order to solve the problem that the roof structure of the vehicle in the prior art cannot meet the arrangement requirements of the hardware, the present application provides a rear roof cross beam for a vehicle. The rear roof cross beam of the present application has a first surface, and a hardware mounting area is provided on the first surface. The hardware mounting area has opposite first and second longitudinal edges, and a sealing portion continuously extending from the first longitudinal edge to the second longitudinal edge is provided on the hardware mounting area. The sealing portion divides the hardware mounting area into at least one dry mounting area and at least one wet mounting area.

[0006] The rear roof cross beam of the present application has a first surface, and a hardware mounting area is arranged on the first surface to accommodate hardware related to auxiliary driving and intelligent networking. The hardware mounting area has opposite first and second longitudinal edges, and a sealing portion is arranged on the hardware mounting area and continuously extends from the first longitudinal edge to the second longitudinal edge. Through the above arrangement, the predetermined hardware arranged in the hardware mounting area is all located between the first and second longitudinal edges, and the sealing portion continuously extends between the first and second longitudinal edges to divide the hardware mounting area into at least two non-communicating areas. Further, the sealing portion divides the hardware mounting area into at least one dry mounting area and at least one wet mounting area. Therefore, hardware that is difficult to waterproof or hardware that will significantly increase the overall vehicle manufacturing cost if waterproofed can be accommodated in the dry mounting area. Even in rainy and snowy weather, the hardware arranged in the dry mounting area will not be affected. In addition, hardware with better air tightness, strict signal emission angle, or hardware that must be connected to the outside of the vehicle to function can be arranged in the wet mounting area. Through the above arrangement, the rear roof cross beam of the present application can meet the hardware arrangement requirements of current highly intelligent vehicles.

[0007] In the above preferred technical solution of the rear roof cross beam for a vehicle, at least one maintenance hole is arranged on the dry mounting area, the maintenance hole penetrates the rear roof cross beam and is adapted to accommodate predetermined hardware of the vehicle. Due to the presence of the sealing portion, the dry mounting area is not adapted to directly communicate with the outside of the vehicle in the state of being mounted on the vehicle, so the hardware arranged in the dry mounting area is relatively complex in the steps of maintenance and disassembly, but through the arrangement of the maintenance hole, after the removal of the roof trim panel of the vehicle for separating the passenger cabin and the body assembly, the hardware accommodated in the maintenance hole can be directly maintained or disassembled. In addition, the doghouse structure (a space for accommodating hardware on a plate-shaped member with a closed bottom surface) is replaced by the maintenance hole, which reduces the occupation of the rear roof cross beam to the interior space of the vehicle and controls the cross-sectional size of the rear roof cross beam to be smaller, thereby ensuring the structural strength of the rear roof cross beam.

[0008] In the above preferred technical solution of the rear roof cross beam for a vehicle, the rear roof cross beam further has a second surface opposite to the first surface; a reinforcing flange is arranged on the edge of the maintenance hole and extends from the edge to the side where the second surface is located. The maintenance hole will affect the strength of the rear roof cross beam to some extent, and the reinforcing flange is arranged to ensure the structural strength of the periphery of the maintenance hole. The reinforcing flange is arranged on the second surface opposite to the first surface, leaving sufficient space on the first surface to install the hardware that needs to be arranged on the rear roof cross beam.

[0009] In the preferred technical scheme of the rear roof cross beam for a vehicle, the hardware mounting area further has opposite first and second transverse edges extending between the first and second longitudinal edges; the sealing portion comprises a first straight section, a bent section and a second straight section connected in sequence, the first and second straight sections extend along the first transverse edge, the two ends of the bent section are positioned on the first transverse edge and the middle part of the bent section intersects with the second transverse edge, so that the first straight section, the bent section and the second transverse edge together enclose the first dry mounting area, the second straight section, the bent section and the second transverse edge together enclose the second dry mounting area, and the bent section and the first transverse edge together enclose the wet mounting area. Through the above arrangement, the hardware mounted on the hardware mounting area is located in the area enclosed by the first transverse edge, the second transverse edge, the first longitudinal edge and the second longitudinal edge. The sealing portion comprises a first straight section, a bent section and a second straight section connected in sequence, and the two ends of the bent section are positioned on the first transverse edge, so that the wet mounting area enclosed by the bent section and the first transverse edge can be arranged at the middle position of the rear roof cross beam, facilitating the hardware in the wet mounting area to be arranged at a suitable position to meet the signal receiving / emitting angle requirement. The first and second straight sections extend along the first transverse edge, and the middle part of the bent section intersects with the second transverse edge, so that the first straight section, the bent section and the second transverse edge together enclose the first dry mounting area, and the second straight section, the bent section and the second transverse edge together enclose the second dry mounting area. The first and second straight sections are arranged to extend along the first transverse edge, so that the area of the dry mounting area is as large as possible to reduce the wet area and facilitate drainage. The middle part of the bent section is arranged to intersect with the second transverse edge, so that the first straight section, the bent section and the second transverse edge together enclose the first dry mounting area, and the second straight section, the bent section and the second transverse edge together enclose the second dry mounting area. The above arrangement reduces the material as much as possible to reduce the vehicle weight under the premise of meeting the hardware arrangement space of the wet mounting area, and divides the dry mounting area into two parts to reduce the risk that all the hardware arranged in the dry mounting area is damaged when the sealing fails.

[0010] In the preferred technical scheme of the rear roof cross beam for a vehicle, the second surface is formed with a reinforcing rib protruding outward. Through the arrangement of the reinforcing rib, the rigidity and strength of the rear roof cross beam are ensured.

[0011] In the preferred technical scheme of the rear roof cross beam for a vehicle, the rear roof cross beam comprises a water flow channel portion having a water flow channel communicating with the wet mounting area. Through the arrangement of the water flow channel portion, the rainwater falling on the roof can be discharged in time through the water flow channel portion. The water flow channel communicates with the wet mounting area, so that the water in the wet mounting area can be discharged in time to protect the hardware in the wet mounting area from the influence of accumulated water.

[0012] In the preferred embodiment of the rear roof crossbeam for a vehicle described above, the rear roof crossbeam further includes a first overlapping portion and a second overlapping portion suitable for fixing to the side panel assembly of the vehicle. The first overlapping portion forms a fixed connection with a first longitudinal edge, and the second overlapping portion forms a fixed connection with a second longitudinal edge. Through this arrangement, the hardware mounting area is located between the first overlapping portion and the second overlapping portion, ensuring the strength of the connection between the rear roof crossbeam and the side panel assembly.

[0013] To address the problem that existing vehicle roof structures cannot meet hardware layout requirements, this invention also provides a vehicle characterized by comprising a roof and a rear roof crossbeam for a vehicle according to any one of claims 1-7, wherein the roof abuts against and forms a sealed connection with the sealing part. Through the above configuration, the roof, the sealing part, and the dry mounting area enclose a space isolated from the vehicle exterior. This space is unaffected by external rainwater and is suitable for placing hardware that is difficult to waterproof or whose waterproofing would significantly increase the overall vehicle manufacturing cost. The roof, the sealing part, and the wet mounting area together enclose a space connected to the vehicle exterior. This space is suitable for placing hardware with good airtightness, strict signal transmission angles, or hardware that requires connection to the vehicle exterior to function. This allows the vehicle of this invention to meet the hardware layout requirements of today's highly intelligent vehicles.

[0014] In the preferred technical solution of the aforementioned vehicle, the roof is made of glass. Existing metal roofs, commonly used in the prior art, severely interfere with the signals of hardware mounted on the rear roof crossbeam. By using a glass roof, the normal signal transmission of the hardware mounted on the rear roof crossbeam is ensured, while also increasing natural light inside the vehicle, providing a wider field of vision, and improving passenger comfort.

[0015] In the preferred embodiment of the aforementioned vehicle, at least one maintenance hole is provided in the dry mounting area of ​​the rear roof crossbeam; at least one predetermined hardware is installed on the side of the roof facing the interior of the vehicle, and each predetermined hardware is accommodated in a corresponding maintenance hole. With this configuration, the hardware is fixed to the roof, eliminating the need for a mounting structure on the rear roof crossbeam, thus ensuring the strength of the rear roof crossbeam and the rear of the vehicle.

[0030] In order to solve the problem that the vehicle roof structure in the prior art cannot meet the hardware arrangement requirement, the present application provides a rear roof cross beam 100 for a vehicle. The rear roof cross beam 100 of the present application has a first surface 40, a hardware mounting area 10a is provided on the first surface 40, the hardware mounting area 10a has opposite first and second longitudinal edges 11 and 12, and a sealing portion 15 continuously extending from the first longitudinal edge 11 to the second longitudinal edge 12 is provided on the hardware mounting area 10a, the sealing portion 15 divides the hardware mounting area 10a into at least one dry mounting area 16 and at least one wet mounting area 17.

[0031] Figure 1 is a top view of an embodiment of the rear roof cross beam for a vehicle of the present application. As Figure 1 shown, in one or more embodiments, the rear roof cross beam 100 for a vehicle of the present application includes a hardware mounting portion 10, a lap joint portion 20, and a gutter portion 30. The rear roof cross beam 100 is made of aluminum alloy material by high-pressure die casting process. Alternatively, the rear roof cross beam 100 can also be made of other suitable metal materials. Alternatively, the lap joint portion 20 or the gutter portion 30 can be omitted. The rear roof cross beam 100 of the present application is a one-piece structure, which only contains one layer of plate-shaped member, rather than a two-layer or multi-layer plate spliced rear roof cross beam assembly.

[0032] Referring to Figure 1 , in one or more embodiments, the rear roof cross beam 100 has a first surface 40. The first surface 40 is Figure 1The first surface 40 is a continuous surface on one side of the plate-shaped rear roof crossbeam 100. When the rear roof crossbeam 100 is mounted on the vehicle, this first surface 40 is adapted to face the exterior of the vehicle. The rear roof crossbeam 100 also has a second surface 50 facing away from the first surface 40, which, when the rear roof crossbeam 100 is mounted on the vehicle, is adapted to face the passenger compartment of the vehicle. The hardware mounting section 10 has a hardware mounting area 10a located on the first surface 40, in which at least one predetermined hardware 700 is adapted to be placed. The predetermined hardware 700 includes, but is not limited to, a 5G & WIFI communication module, a GPS positioning module, and a camera. The hardware mounting area 10a has opposing first longitudinal edges 11 and second longitudinal edges 12, and a first lateral edge 13 and a second lateral edge 14 extending between the first longitudinal edges 11 and the second longitudinal edges 12. The first longitudinal edge 11, the second longitudinal edge 12, the first lateral edge 13, and the second lateral edge 14 together form a generally rectangular area for mounting the predetermined hardware 700. When mounted on a vehicle, both the first lateral edge 13 and the second lateral edge 14 extend substantially laterally along the vehicle, with the first lateral edge 13 located closer to the rear of the vehicle. Alternatively, the hardware mounting area 10a can also be configured in other suitable shapes.

[0033] Figure 2 yes Figure 1 The diagram shows a partial axonometric view of an embodiment of the present invention for use in a vehicle's rear roof crossbeam. (See attached image.) Figure 1 and Figure 2 As shown, in one or more embodiments, a sealing portion 15 is provided on the hardware mounting area 10a, extending continuously from a first longitudinal edge 11 to a second longitudinal edge 12. In one or more embodiments, the sealing portion 15 is integrally formed on the rear top crossbeam 100 during casting. The sealing portion 15 protrudes outward from the first surface 40 and has a top wall 151 ( Figure 4The 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 dry mounting areas 16 and wet mounting areas 17 spaced apart from each other. Alternatively, the sealing portion 15 can also be configured in other suitable shapes. Alternatively, the sealing portion 15 can also be provided on the hardware mounting area 10a by other suitable means, for example, fixed on the hardware mounting area 10a by fasteners using rubber material. In one or more embodiments, a plurality of supporting protrusions 152 are provided on the top wall 151. The supporting protrusions 152 protrude upward from the outer wall 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 can have a large flatness error, resulting in a locally uneven phenomenon. By the provision of the supporting protrusions 152, the roof 600 directly abuts against the plurality of supporting protrusions 152, and at other positions of the top wall 151 where no supporting protrusions 152 are provided, the effect of the manufacturing deviation of the top wall 151 is eliminated by filling the glue. The glue includes but is not limited to sealant, glass glue, etc.

[0034] With continued reference to Figure 1 In one or more embodiments, the sealing portion 15 includes a first straight section 153, a bent section 154 and a second straight section 155 connected in sequence. In one or more embodiments, the bent section 154 is configured in a substantially arc shape and both ends of the bent section 154 are provided on the first lateral edge 13 so as to enclose the wet mounting area 17 together with the inner side 1541 of the bent section 154 and the first lateral edge 13; and enclose the dry mounting area 16 together with the outer side 1542 of the bent section 154, the first straight section 153 and the second straight section 155. Alternatively, both ends of the bent section 154 can also be provided at other suitable positions. In one or more embodiments, both ends of the bent section 154 are connected to the first straight section 153 and the second straight section 155, respectively. Alternatively, both ends of the bent section 154 can also be configured 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 the dry mounting area 16 with the largest possible area. Alternatively, the first straight section 153 and the second straight section 155 can also be configured away from the first lateral edge 13, in which case when both ends of the bent section 154 are still provided on the first lateral edge 13, the first straight section 153 and the second straight section 155 each enclose 1 wet mounting area 17 with the outer side 1542 of the bent section 154 and the first lateral edge 13, respectively, plus the wet mounting area 17 enclosed by the inner side 1541 of the bent section 154 and the first lateral edge 13, for a total of 3 wet mounting areas 17. In one or more embodiments, the middle portion of the bent section 154 intersects the second lateral edge 14. As shown in FIG. 1, the middle portion of the bent section 154 intersects the second lateral edge 14 at an angle, and the intersection between the bent section 154 and the second lateral edge 14 is substantially perpendicular to the first lateral edge 13. Alternatively, the intersection between the bent section 154 and the second lateral edge 14 can also be configured in other suitable shapes. Figure 1As shown, the middle of the substantially arc-shaped bent section 154 protrudes beyond the second transverse edge 14, and divides the dry mounting area 16 surrounded by the second transverse edge 14, the first straight section 153, the second straight section 155, and the outer side 1542 of the bent section 154 into two dry mounting areas 16, i.e. a first dry mounting area 161 on the left side of the bent section 154 and a second dry mounting area 162 on the right side of the bent section 154. Alternatively, the middle of the bent section 154 can be arranged not to intersect the second transverse edge 14, so that the dry mounting area 16 is continuous. In alternative embodiments, the sealing portion 15 can also be configured in other suitable shapes that continuously extend between the first longitudinal edge 11 and the second longitudinal edge 12, and the hardware mounting area is configured to have other suitable numbers of dry mounting areas and other suitable numbers of wet mounting areas.

[0035] With continued reference to Figure 1 In one or more embodiments, the sealing portion 15 further includes a third straight section 156 extending along the second transverse edge 14. The third straight section 156 can be configured to be discontinuous, i.e. having an interrupted gap 1561 formed thereon. With the third straight section 156, the roof header 600 has more connection areas with the sealing portion 15, so as to facilitate the connection strength of the roof header 600 with the rear roof cross beam 100. Alternatively, the third straight section 156 can be omitted. In one or more embodiments, the gap 1561 can be used for positioning of the roof header 600. Alternatively, the gap 1561 can also be used for passing a wiring harness. In one or more embodiments, the sealing portion 15 further includes a fourth straight section 157 extending along the first longitudinal edge 11 and / or the second longitudinal edge 12. With the fourth straight section 157, the roof header 600 has more connection areas with the sealing portion 15, so as to facilitate the connection strength of the roof header 600 with the rear roof cross beam 100. Alternatively, the fourth straight section 157 can be omitted.

[0036] It is noted that the first straight section 153, the second straight section 155, the third straight section 156, and the fourth straight section 157 are substantially straight, but can also be configured to be slightly curved according to the shapes of the first longitudinal edge 11, the second longitudinal edge 12, the first transverse edge 13, and the second transverse edge 14.

[0037] With continued reference to Figure 1 In one or more embodiments, each of the first dry mounting area 161 and the second dry mounting area 162 has a repair hole 163 formed therein. Each repair hole 163 penetrates the rear roof cross beam 100, and a body of a predetermined hardware 700 is adapted to be received in the repair hole 163. The repair hole 163 is sized to match the predetermined hardware 700 received therein. In one or more embodiments, a reinforcing flange 1631 is provided at the edge of the repair hole 163. Figure 7The reinforcing flange 1631 is integrally formed on the rear top cross beam 100 at the time of casting and extends from the edge of the service hole 163 toward the side where the second surface 50 is located so as not to encroach on the space of the hardware mounting area 10a. Alternatively, the service hole 163 in each dry mounting area 16 can also be configured in other numbers greater than 1, such as 2, 3, etc. Alternatively, the provision of the service hole 163 can also be cancelled and the predetermined hardware 700 is installed by forming a plurality of doghouse structures with closed bottom surfaces on the rear top cross beam 100.

[0038] With continued reference to Figure 2 In one or more embodiments, the inner side 1541 of the bent section 154 and the first lateral edge 13 enclose the wet mounting area 17. In the state of being mounted on the vehicle, the wet mounting area 17 is adapted to form communication with the external space of the vehicle. In the wet mounting area 17, predetermined hardware 700 with strict signal emission / reception angles, such as a camera 701, a lidar, or a V2X module 702 (i.e., Vehicle to Everything, “X” can represent any object capable of communicating with the vehicle, and the vehicle can “communicate” with other things in the outside world through the V2X module 702), etc. are adapted to be provided. In one or more embodiments, since the wet mounting area 17 is adapted to directly form communication with the external space of the vehicle, in the state of being mounted on the vehicle, the bottom wall of the wet mounting area 17 has an inclined downward slope (as shown in Figure 3 , the first lateral edge 13 is the lowest part of the wet mounting area 17. In addition, in one or more embodiments, in order to meet the needs of a plurality of predetermined hardware 700 provided in the wet mounting area 17, the plurality of predetermined hardware 700 is provided along a mounting gradient. For example, in the wet mounting area 17, a camera 701 with better air tightness and a V2X module 702 are provided, and the V2X module 702 is provided below the camera 701. In one or more embodiments, the camera 701 is provided on the wet mounting area 17 by a camera 701 bracket (not shown in the figure) so as to be configured to be higher than the V2X module 702. Alternatively, the camera 701 can also be provided in the wet mounting area 17 by other suitable means. In one or more embodiments, as shown in Figure 2 , a doghouse structure 171 (i.e., a recess recessed from the first surface 40 toward the inside of the rear top cross beam 100) is formed on the wet mounting area 17 of the rear top cross beam 100. The V2X module 702 is provided in the doghouse structure 171 so as to be configured to be lower than the camera 701 so as not to interfere with the visual range of the camera 701. Alternatively, the V2X module 702 can also be fixed in the wet mounting area 17 by other suitable means. In alternative embodiments, the installation gradient can also be cancelled.

As Figure 3 As shown, in one or more embodiments, the gutter section 30 forms a fixed connection with the first lateral edge 13. The gutter section 30 has a gutter 31 that is in communication with the wet-out area 17, and in a state where the rear roof cross beam 100 is installed on the vehicle, the gutter 31 is located below the wet-out area 17 so as to form a hydraulic slope, such that water of the wet-out area 17 can be smoothly drained through the gutter 31. As Figure 1 Figure 4 As shown, in one or more embodiments, a tailgate mounting section 32 is provided on the gutter section 30 so as to facilitate installation of a tailgate hinge 321. Alternatively, the tailgate mounting section 32 can also be omitted, and the tailgate hinge 321 is installed on other suitable locations of the vehicle, for example, the tailgate mounting section 32 is provided on the CD pillar. In one or more embodiments, the gutter section 30 has a tailgate edge 33 that is adapted to enclose a tailgate opening, and a tailgate weatherstrip 331 is adapted to be provided on the tailgate edge 33 so as to prevent rainwater in the gutter section 30 from entering the interior of the vehicle through the tailgate.
