Technical Field

[0001] This application relates to the field of vehicle body structure technology, specifically to a roof front crossbeam assembly, a vehicle body, and a vehicle. Background Technology

[0002] The front crossbeam assembly of the roof is installed in the front area of ​​the vehicle roof, providing mounting points for the windshield, panoramic sunroof, lidar, roof liner, and front dome lights. At the same time, the front crossbeam assembly of the roof plays a very important role in the vehicle's roof compression resistance, bending and torsional performance, overall vehicle fatigue durability, and overall vehicle NVH. This requires the front crossbeam assembly of the roof to not only meet various performance requirements, but also to meet the requirements of head safety envelope and lightweight design.

[0003] In traditional vehicles, the roof front crossbeam assembly used for mounting panoramic sunroofs or lidar systems consists of upper and lower plates welded together to form a cavity. The structure of the roof front crossbeam assembly is influenced by the roof design and interior visibility, limiting the cross-sectional dimensions of the cavity between the upper and lower plates and resulting in lower structural strength. Current technologies typically increase the thickness of the upper and lower plates and replace materials to meet performance requirements, leading to increased weight and cost, which is detrimental to overall vehicle lightweighting and cost control. Utility Model Content

[0004] One objective of this application is to provide a roof front crossbeam assembly to solve the problems of heavy weight and high cost of the existing roof front crossbeam assembly; another objective is to provide a vehicle body; and a third objective is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A roof front crossbeam assembly includes a first plate, a second plate, and a connecting plate. The roof front crossbeam assembly has a first direction and a second direction that are perpendicular to each other. The first plate and the second plate are disposed along the first direction and enclose to form a first cavity. The first plate is adapted to be connected to a side panel assembly of a vehicle body. The connecting plate is disposed on at least one side of the second plate along the second direction, and the connecting plate and the first plate are spaced apart along the first direction. One side of the connecting plate is connected to the second plate, and the other side of the connecting plate is adapted to be connected to the side panel assembly. The connecting plate, the first plate, the second plate, and the side panel assembly enclose to form a second cavity, and the second cavity and the first cavity are spaced apart along the second direction.

[0007] Based on the aforementioned technical means, the front crossbeam assembly of the roof features a dual-cavity spaced structure, effectively improving its structural strength within the limited roof space, while providing a stable and reliable mounting base for various components at the front of the roof. Furthermore, the front crossbeam assembly of this application, while ensuring performance indicators, effectively reduces its weight through a cavity design, achieving lightweighting and thus lowering costs.

[0008] Furthermore, the second plate includes a body and a flange; the body has a first groove, and the first plate covers the opening of the first groove to form the first cavity; the flange is arranged circumferentially around at least a portion of the body, one end of the flange is connected to the body, and the other end of the flange extends in a direction away from the first groove and is connected to the first plate; the connecting plate is connected to the side opposite to the first plate from the body.

[0009] According to the above technical means, by connecting the flange and the body, the connection area between the second plate and the first plate is increased, thereby improving the connection strength between the second plate and the first plate, and thus improving the structural stiffness, strength, buckling resistance and fatigue life of the first cavity located between the second plate and the first plate.

[0010] Furthermore, the first plate is provided with a clearance hole, which communicates with the first cavity; the connection between the connecting plate and the main body is arranged opposite to the clearance hole, which provides clearance space for the connection between the connecting plate and the main body.

[0011] According to the above technical means, when the connecting plate is connected to the body, it is convenient to provide clearance space through the clearance hole, thereby facilitating the connection between the connecting plate and the body.

[0012] Furthermore, the connecting plate has a first positioning part facing the side, and the main body has a second positioning part corresponding to the first positioning part, and the first positioning part and the second positioning part are connected.

[0013] According to the above-mentioned technical means, the positioning of the two parts is achieved by connecting the first positioning part and the second positioning part, thereby providing higher precision when welding the two parts.

[0014] Furthermore, one of the first positioning part and the second positioning part is configured as a positioning buckle, and the other is configured as a positioning hole, wherein the positioning buckle and the positioning hole are engaged.

[0015] The aforementioned technical means facilitate production and manufacturing.

[0016] Furthermore, there are two connecting plates; the two connecting plates are respectively disposed on both sides of the second plate along the second direction, and each connecting plate, together with the first plate, the second plate and the side assembly, forms the second cavity.

[0017] The aforementioned technical means ensure that the front crossbeam assembly of the roof is subjected to uniform force on both sides along the second direction.

[0018] Furthermore, the first plate is provided with a second groove; the second groove is recessed from the side surface of the first plate away from the second plate towards the direction close to the first cavity.

[0019] According to the above-mentioned technical means, the cross-sectional shape of the first plate is changed by the groove design, and its cross-sectional moment of inertia is increased, so that the first plate can withstand a larger load without significant bending or buckling.

[0020] Furthermore, the thickness of the connecting plate along the first direction is greater than the thickness of the second plate along the first direction; and / or, the thickness of the second plate along the first direction is greater than the thickness of the first plate along the first direction.

[0021] By employing the aforementioned technical methods, the bending resistance and deformation resistance of the front crossbeam assembly of the roof are enhanced, effectively avoiding localized stress concentration and improving overall connection reliability and structural lifespan.

[0022] Furthermore, the second plate is a thermoformed part; and / or, the first plate and the connecting plate are stamped parts.

[0023] Based on the above technical means, a lightweight and high-strength composite load-bearing system is constructed by configuring differentiated materials and processes for thermoformed and stamped parts.

[0024] A vehicle body includes a roof front crossbeam assembly and a side panel assembly as described above; a first panel is connected to the side panel assembly, and a connecting plate is connected to the side panel assembly on the side away from the second panel.

[0025] Based on the aforementioned technical means, the vehicle body structure is connected to the side assembly via a first plate and a connecting plate, forming a dual support. The first plate acts as the main support to resist the impact force on the roof, while the connecting plate acts as an auxiliary support to disperse the lateral impact energy. The two connection points form a closed-loop frame, significantly reducing the stress at the connection points, avoiding stress concentration, and improving the roof's compressive strength, making the overall structure lighter and safer.

[0026] Furthermore, the vehicle body also includes a windshield and an adhesive component; the windshield is mounted on the first panel, and the adhesive component is disposed between the windshield and the first panel, the adhesive component being used to connect the windshield and the first panel; and / or, the vehicle body also includes a panoramic sunroof and an adhesive component; the panoramic sunroof is mounted on the first panel, and the adhesive component is disposed between the panoramic sunroof and the first panel, the adhesive component being used to connect the panoramic sunroof and the first panel.

[0027] According to the above-mentioned technical means, the windshield and the first panel are connected by adhesive, as are the sunroof glass and the first panel, thereby preventing rainwater, dust, noise and other external factors from entering the driver's cabin and ensuring a good riding experience environment in the driver's cabin.

[0028] A vehicle comprising the roof front crossbeam assembly as described above, or comprising the body as described above.

[0029] Based on the aforementioned technical means, the front crossbeam assembly of the roof has a dual-cavity spaced structure, thereby effectively improving the overall rigidity, strength, and fatigue durability of the front crossbeam assembly within the limited roof space, while providing a stable and reliable mounting foundation for various components at the front end of the roof. Furthermore, the front crossbeam assembly of this application, while ensuring performance indicators, can effectively reduce component weight and reliance on high-grade, high-thickness materials, thereby reducing manufacturing costs and achieving lightweighting.

[0041] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0043] like Figures 1 to 2 As shown, a front crossbeam assembly 10 for a roof includes a first plate 11, a second plate 12, and a connecting plate 13. The front crossbeam assembly 10 has a first direction Z and a second direction Y that are perpendicular to each other. The first plate 11 and the second plate 12 are arranged along the first direction Z and enclose each other to form a first cavity 14. The first plate 11 is adapted to be connected to a side panel assembly 20 of the vehicle body. The connecting plate 13 is disposed on at least one side of the second plate 12 along the second direction Y, and the connecting plate 13 and the first plate 11 are spaced apart along the first direction Z. One side of the connecting plate 13 is connected to the second plate 12, and the other side of the connecting plate 13 is adapted to be connected to the side panel assembly 20. The connecting plate 13, the first plate 11, the second plate 12, and the side panel assembly 20 enclose each other to form a second cavity 15. The second cavity 15 and the first cavity 14 are spaced apart along the second direction Y.

[0044] It should be noted that the first direction Z is the height direction of the vehicle, the second direction Y is the width direction of the vehicle, and the third direction X is the length direction of the vehicle.

[0045] In this embodiment, a first cavity 14 is formed by arranging and enclosing a first plate 11 and a second plate 12 along a first direction Z. A connecting plate 13 is disposed on one side of the second plate 12 along a second direction Y, and the connecting plate 13 and the first plate 11 are spaced apart along the first direction Z. One side of the connecting plate 13 is connected to the second plate 12, and the other side of the connecting plate 13 is connected to the side wall assembly 20 to form a second cavity 15. Thus, the roof front crossbeam assembly 10 has a double-cavity spaced-apart structure, effectively improving the structural strength of the roof front crossbeam assembly 10 within the limited roof space, while providing a stable and reliable mounting base for various components at the front end of the roof. Furthermore, the roof front crossbeam assembly 10 of this application, while ensuring performance indicators, effectively reduces the weight of the roof front crossbeam assembly 10 through the cavity design, achieving lightweighting and thus reducing costs.

[0046] In addition, the dual-cavity synergistic load-bearing mechanism can enhance the overall rigidity of the front crossbeam assembly 10 of the roof and the stability of local mounting points, thereby improving the vehicle's noise, vibration, and harshness (NVH) performance.

[0047] Optionally, Figures 2 to 5 As shown, the second plate 12 includes a body 121 and a flange 122; the body 121 has a first groove 123, and the first plate 11 covers the opening of the first groove 123 to form a first cavity 14; the flange 122 is arranged around at least part of the body 121 in a circumferential direction, one end of the flange 122 is connected to the body 121, and the other end of the flange 122 extends in a direction away from the first groove 123 and is connected to the first plate 11; the connecting plate 13 is connected to the side of the body 121 that is away from the first plate 11.

[0048] In this embodiment, a first cavity 14 is formed by covering the opening of the first groove 123 with a first plate 11. A flange 122 is arranged circumferentially around at least a portion of the body 121. One end of the flange 122 is connected to the body 121, and the other end of the flange 122 extends away from the first groove 123 and is connected to the first plate 11. A connecting plate 13 is connected to the side of the body 121 that is away from the first plate 11. In this way, by connecting the flange 122 and the body 121, the connection area between the second plate 12 and the first plate 11 is increased, thereby improving the connection strength between the second plate 12 and the first plate 11, and thus improving the structural stiffness, strength, buckling resistance and fatigue life of the first cavity 14 located between the second plate 12 and the first plate 11.

[0049] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, flanges 122 are provided around the body 121, and the flanges 122 are connected to the first plate 11 to form a relatively closed first cavity 14.

[0050] Different types of mounting holes are provided on the side of the main body 121 away from the first plate 11. The mounting holes can be used to install components such as linings, lamps, and light shields. The wiring of these components can be set in the relatively sealed first cavity 14 to avoid damage to the wiring due to external forces.

[0051] Optionally, such as Figure 3 and Figure 4 As shown, the first plate 11 is provided with a clearance hole 111, which communicates with the first cavity 14; the connection between the connecting plate 13 and the body 121 is arranged opposite to the clearance hole 111, and the clearance hole 111 is used to provide clearance space for the connection between the connecting plate 13 and the body 121.

[0052] In this embodiment, a clearance hole 111 is provided in the first plate 11, which communicates with the first cavity 14. The connection point between the connecting plate 13 and the body 121 is positioned opposite to the clearance hole 111. This allows for clearance space to be provided through the clearance hole 111 when the connecting plate 13 is connected to the body 121, thus facilitating the connection between the connecting plate 13 and the body 121.

[0053] Specifically, such as Figure 4 As shown, there are two clearance holes 111, which are spaced apart along the third direction X, thereby providing more clearance space for the connection between the connecting plate 13 and the body 121.

[0054] In some embodiments, the connecting plate 13 and the body 121 are connected by welding. Specifically, a welding torch can be inserted into the clearance hole 111, and the connecting plate 13 and the body 121 can be welded together by spot welding. For example, the connecting plate 13 and the body 121 can be welded together by setting four spot welding connection points. Of course, the connecting plate 13 and the body 121 can also be connected by riveting, and this embodiment of the application does not limit this.

[0055] Optionally, such as Figure 3 As shown, the connecting plate 13 is provided with a first positioning part 131 on one side, and the body 121 is provided with a second positioning part 124 corresponding to the first positioning part 131. The first positioning part 131 and the second positioning part 124 are connected.

[0056] In this embodiment, a first positioning part 131 is provided on one side of the connecting plate 13, and a second positioning part 124 is provided in the body 121, with the first positioning part 131 and the second positioning part 124 connected. Thus, the connection between the first positioning part 131 and the second positioning part 124 achieves positioning of both, thereby providing higher precision during welding.

[0057] In some embodiments, the first positioning part 131 can be configured as a wedge block, and the second positioning part 124 can be configured as a beveled groove. The wedge block and the beveled groove form an interference fit, which eliminates the risk of relative misalignment between the connecting plate 13 and the body 121 before welding, thereby reducing the cumulative tolerance of assembly.

[0058] Optionally, such as Figure 3 As shown, one of the first positioning part 131 and the second positioning part 124 is configured as a positioning buckle, and the other is configured as a positioning hole, and the positioning buckle and the positioning hole are engaged.

[0059] In this embodiment, one of the first positioning part 131 and the second positioning part 124 is configured as a positioning buckle, and the other is configured as a positioning hole, with the positioning buckle and the positioning hole engaging. This facilitates production and manufacturing.

[0060] Specifically, such as Figure 3 As shown, the positioning buckle is bent toward the first cavity 14; this allows the bent positioning buckle to pass through the positioning hole and connect to the body 121.

[0061] Optionally, such as Figure 2 As shown, there are two connecting plates 13; the two connecting plates 13 are respectively located on both sides of the second plate 12 along the second direction Y, and each connecting plate 13, together with the first plate 11, the second plate 12 and the side assembly 20, forms a second cavity 15.

[0062] In this embodiment, two connecting plates 13 are respectively disposed on both sides of the second plate 12 along the second direction Y, and each connecting plate 13, together with the first plate 11, the second plate 12 and the side assembly 20, forms a second cavity 15. In this way, the force on both sides of the top cover front crossbeam assembly 10 along the second direction Y is uniform.

[0063] In some embodiments, multiple partition plates (not shown in the figure) may be provided in the first cavity 14 to divide the first cavity 14 into multiple sub-cavities, thereby changing the moment of inertia and stiffness of the top cover front crossbeam assembly 10 and increasing its structural strength.

[0064] Optionally, such as Figure 4 As shown, the first plate 11 is provided with a second groove 112; the second groove 112 is recessed from the side surface of the first plate 11 away from the second plate 12 toward the direction close to the first cavity 14.

[0065] In this embodiment, a second groove 112 is provided in the first plate 11; the second groove 112 is recessed from the side surface of the first plate 11 away from the second plate 12 toward the direction close to the first cavity 14. In this way, the cross-sectional shape of the first plate 11 is changed by the groove design, increasing its cross-sectional moment of inertia, so that the first plate 11 can withstand a larger load without significant bending or buckling.

[0066] In some embodiments, two second grooves 112 are provided, and the two second grooves 112 are spaced apart along the third direction X, so as to provide a larger moment of inertia for the first plate 11, thereby enhancing the structural strength of the first plate 11.

[0067] It should be noted that the second groove 112 can be a rectangular groove or an arc-shaped groove; of course, the second groove 112 can be continuous or discontinuous, and this embodiment of the application does not impose any restrictions.

[0068] Optionally, the thickness of the connecting plate 13 along the first direction Z is greater than the thickness of the second plate 12 along the first direction Z.

[0069] In this embodiment, since the second plate 12 is connected to the side panel assembly 20 via a connecting plate 13, the thickness of the connecting plate 13 along the first direction Z is set to be greater than the thickness of the second plate 12 along the first direction Z. Thus, when the second plate 12 is subjected to load, the thicker connecting plate 13 acts as the main load-bearing component, enhancing the bending resistance and deformation resistance of the top cover front crossbeam assembly 10, effectively avoiding local stress concentration, and improving overall connection reliability and structural lifespan.

[0070] Optionally, the thickness of the second plate 12 along the first direction Z is greater than the thickness of the first plate 11 along the first direction Z.

[0071] In this embodiment, since the second plate 12 and the first plate 11 are connected along the first direction Z, the thickness of the second plate 12 along the first direction Z is set to be greater than the thickness of the first plate 11 along the first direction Z. Thus, when the second plate 12 is subjected to a load, the thicker second plate 12 acts as the main load-bearing component, avoiding damage to the thinner first plate 11 caused by stress.

[0072] Optionally, the second plate 12 is a thermoformed part; and / or, the first plate 11 and the connecting plate 13 are stamped parts.

[0073] In this embodiment, the second plate 12 is a thermoformed part, and the first plate 11 and the connecting plate 13 are stamped parts. Thus, a lightweight and high-strength composite load-bearing system is constructed through the differentiated material and process configurations of the thermoformed and stamped parts.

[0074] Specifically, the thermoformed second plate 12, relying on the high-temperature phase transformation strengthening effect, still forms an impact-resistant core skeleton even with reduced thickness; the stamped first plate 11 and connecting plate 13, thanks to their cold-forming adaptability, absorb assembly stress and vibration energy through elastic deformation. This process combination achieves lightweight, high reliability, and low-cost mass production.

[0075] It should be noted that thermoformed parts refer to structural components made using thermoforming processes. Thermoforming is an advanced metal sheet processing technology that integrates heating, stamping, and quenching, enabling the production of complex stamped parts with ultra-high strength, high precision, and lightweight properties. Stamped parts, on the other hand, refer to structural components made using stamping processes. Stamping is a cold working process that uses a press and dies to apply external force to metal sheets, strips, tubes, etc., causing plastic deformation or separation to obtain parts or blanks with the desired shape, size, and performance.

[0076] Optionally, such as Figure 1 and Figure 8 As shown, a vehicle body is also proposed, including a roof front crossbeam assembly 10 and a side panel assembly 20 as described above; a first plate 11 is connected to the side panel assembly 20, and a connecting plate 13 is connected to the side panel assembly 20 on the side away from the second plate 12.

[0077] In this embodiment, the roof front crossbeam assembly 10 and the side panel assembly 20 are connected; the first plate 11 is connected to the side panel assembly 20, and the connecting plate 13 is connected to the side panel assembly 20 on the side away from the second plate 12. Thus, the vehicle body structure is connected to the side panel assembly 20 via the first plate 11 and the connecting plate 13, forming a dual support. The first plate 11 acts as the main support to resist the impact force on the roof, while the connecting plate 13 acts as an auxiliary support to disperse the lateral impact energy. The two connection points form a closed-loop frame, significantly reducing the stress at the connection points, avoiding stress concentration, and simultaneously improving the roof's compressive strength, making the overall structure lighter and safer.

[0078] Specifically, such as Figure 1 and Figure 8 As shown, the first plate 11 is mounted on the side panel assembly 20 and welded to the side panel assembly 20, and the connecting plate 13 is located on the side of the side panel assembly 20 away from the first plate 11 and welded to the side panel assembly 20.

[0079] Optionally, such as Figure 7As shown, the vehicle body also includes a windshield 40 and an adhesive component 30; the windshield 40 is mounted on the first panel 11, and the adhesive component 30 is located between the windshield 40 and the first panel 11, and the adhesive component 30 is used to connect the windshield 40 and the first panel 11.

[0080] In this embodiment, the windshield 40 is mounted on the first panel 11, and the adhesive 30 is disposed between the windshield 40 and the first panel 11. This allows the windshield 40 and the first panel 11 to be connected by the adhesive 30, thereby preventing rainwater, dust, noise, and other external elements from entering the driver's cabin and ensuring a comfortable riding environment inside the driver's cabin.

[0081] In some embodiments, the adhesive 30 can be made of silicone sealant, and two layers of silicone sealant can be applied alternately to optimize vehicle acceleration noise, reduce the vibration response sensitivity of the front crossbeam assembly 10, improve NVH performance, and enhance ride comfort. Of course, the adhesive 30 can also be made of epoxy resin adhesive. Those skilled in the art can choose according to actual needs, and this application does not impose any limitations.

[0082] Furthermore, such as Figure 7 As shown, the first layer of glass glue is applied at the connection between the first plate 11 and the second plate 12, and the second layer of glass glue is applied on the first plate 11.

[0083] Optionally, such as Figure 7 As shown, the vehicle body also includes a panoramic glass 50 and an adhesive component 30; the panoramic glass 50 is mounted on the first panel 11, and the adhesive component 30 is located between the panoramic glass 50 and the first panel 11, and the adhesive component 30 is used to connect the panoramic glass 50 and the first panel 11.

[0084] In this embodiment, the panoramic glass 50 is mounted on the first panel 11, and the adhesive 30 is disposed between the panoramic glass 50 and the first panel 11. This allows the panoramic glass 50 and the first panel 11 to be connected by the adhesive 30, thereby preventing rainwater, dust, noise, and other external factors from entering the driver's cabin and ensuring a good riding experience environment inside the driver's cabin.

[0085] In some embodiments, the adhesive 30 used between the skylight glass 50 and the first panel 11 may be the same as or different from the adhesive 30 used between the windshield glass 40 and the first panel 11. This application embodiment does not limit this.

[0086] In some embodiments, the windshield and the sunroof 50 are both mounted on the first plate 11, meaning that the windshield and the sunroof 50 are supported by the same structure, which effectively ensures the matching accuracy of the windshield and the sunroof 50, effectively ensures the sealing and waterproof performance of the whole vehicle, and makes the appearance more streamlined and beautiful.

[0087] In other embodiments, such as Figure 7 As shown, the vehicle body also includes a connector 60, one end of which is connected to the panoramic glass 50, and the other end of which is connected to the windshield, thereby improving the connection strength between the panoramic glass 50 and the windshield.

[0088] Alternatively, a vehicle is also proposed, including the roof front crossbeam assembly 10 as described above, or including the body as described above.

[0089] In this embodiment, a first cavity 14 is formed by arranging and enclosing a first plate 11 and a second plate 12 along a first direction Z. A connecting plate 13 is disposed on one side of the second plate 12 along a second direction Y, and the connecting plate 13 and the first plate 11 are spaced apart along the first direction Z. One side of the connecting plate 13 is connected to the second plate 12, and the other side of the connecting plate 13 is connected to the side wall assembly 20 to form a second cavity 15. Thus, the roof front crossbeam assembly 10 has a double-cavity spaced-apart structure, effectively improving the structural strength of the roof front crossbeam assembly 10 within the limited roof space, while providing a stable and reliable mounting base for various components at the front end of the roof. Furthermore, the roof front crossbeam assembly 10 of this application, while ensuring performance indicators, effectively reduces the weight of the roof front crossbeam assembly 10 through the cavity design, achieving lightweighting and thus reducing costs.

[0090] The above embodiments are merely preferred embodiments provided to fully illustrate this application, and the scope of protection of this application is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on this application are all within the scope of protection of this application.
