Description

Technical Field

[0001] This application relates to the field of vehicle component manufacturing technology, and in particular to a roof front crossbeam assembly and a vehicle. Background Technology

[0002] The front crossbeam of the roof is located on the front side of the vehicle roof and is usually connected to the side panel components and the roof body. It plays multiple roles, such as supporting the roof, enhancing the body strength, dispersing collision energy, and carrying electrical components and trim.

[0003] In related technical solutions, the front crossbeam of the roof typically includes an outer panel and an inner panel arranged opposite each other along the vehicle's height direction. The inner panel has a groove on the side facing the outer panel, and the outer panel covers the inner panel. The two panels are fixed together by welding, bolts, or other methods. The two ends of the front crossbeam of the roof are connected and fixed to the side panel assemblies on both sides along the vehicle's width direction.

[0004] However, the overall strength of the front crossbeam of the roof is relatively low when the relevant technology is used, and it is easy to deform and bend when the vehicle is involved in a collision, which affects driving safety. Utility Model Content

[0005] In view of this, the present application provides a roof front crossbeam assembly and a vehicle. The present application is beneficial to improving the strength of the roof front crossbeam assembly, reducing the risk of deformation and bending during a collision, and improving driving safety.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] This application embodiment provides a front crossbeam assembly for a roof cover, including: a front crossbeam for a roof cover, the front crossbeam for a roof cover comprising:

[0008] outer panel;

[0009] The inner plate and the outer plate are disposed opposite each other along a first direction. The inner plate has a first groove on the side facing the outer plate, and the first groove is disposed along a second direction.

[0010] A reinforcing plate is connected to the inner plate and is located on one side of the inner plate along a third direction. The side of the reinforcing plate facing the outer plate is provided with a second groove, which is arranged along the second direction.

[0011] The outer plate covers the inner plate and the reinforcing plate. The outer plate and the first groove of the inner plate together form a first cavity, and the outer plate and the second groove of the reinforcing plate together form a second cavity.

[0012] This embodiment of the application adds a reinforcing plate to one side of the inner panel, and provides a first groove on the inner panel and a second groove on the reinforcing plate, so that the outer panel and the inner panel form a first cavity, and the outer panel and the reinforcing plate form a second cavity. Compared with related technologies, this embodiment of the application improves the strength of the front crossbeam assembly of the roof, thereby reducing the risk of deformation and bending during a collision and improving driving safety.

[0013] In one possible implementation of this application, the inner panel includes an inner panel bottom plate and a plurality of inner panel side walls, the plurality of inner panel side walls being connected end to end and all connected to the inner panel bottom plate; the plurality of inner panel side walls include a first inner panel side wall perpendicular to the third direction, along the first direction, the side of the first inner panel side wall opposite to the inner panel bottom plate is provided with a first flange, along the third direction, the first flange is disposed opposite to the first groove;

[0014] The reinforcing plate includes a reinforcing plate base plate and multiple reinforcing plate sidewalls. The multiple reinforcing plate sidewalls are connected end to end and are all connected to the reinforcing plate base plate. The multiple reinforcing plate sidewalls include a first reinforcing plate sidewall perpendicular to the third direction. The first reinforcing plate sidewall is disposed close to the first inner plate sidewall. Along the first direction, the side of the first reinforcing plate sidewall opposite to the reinforcing plate base plate is provided with a second flange. Along the third direction, the second flange is disposed opposite to the second groove.

[0015] The second flange overlaps the first flange and is connected to the first flange; the outer plate is connected to the second flange, the multiple inner plate sidewalls, and the multiple reinforcing plate sidewalls.

[0016] In this embodiment, the reinforcing plate is connected to the first flange of the inner plate via the second flange. The outer plate is not only connected to the top of each side wall of the inner plate and the top of each side wall of the reinforcing plate, but also connected to the second flange, thereby increasing the connection area between the outer plate and the inner plate and the reinforcing plate, thereby further improving the strength of the front crossbeam assembly of the roof and reducing the risk of deformation, bending and other damage during a collision.

[0017] In one possible implementation of this application, a third groove is provided on the side of the outer plate opposite to the inner plate along the first direction.

[0018] This embodiment of the application provides a third groove on the side of the outer panel away from the inner panel. Compared with the near-planar structure in related technologies, this can greatly improve the deformation and torsion resistance of the outer panel, thereby helping to further improve the strength of the front crossbeam assembly of the top cover.

[0019] In one possible implementation of this application, a mass block is also included, which is located within the first groove.

[0020] By setting a mass block, the overall weight of the front crossbeam assembly of the roof can be increased, which helps to reduce noise and vibration inside the vehicle. The mass block also helps to further improve the strength of the front crossbeam assembly of the roof, thereby improving the vehicle's driving stability and safety.

[0021] In one possible implementation of this application, the inner plate is provided with a plurality of first through holes, the mass block is provided with a plurality of first fixing holes, and the first fastener passes through the first through holes and connects to the corresponding first fixing holes.

[0022] The first fastener in this embodiment can be a screw, bolt, etc. The first fastener passes through the first through hole on the inner plate and is assembled and fixed with the first fixing hole on the mass block, which helps to improve the assembly efficiency of the mass block and facilitates subsequent maintenance and disassembly.

[0023] In one possible implementation of this application, a reinforcing plate is further included, the reinforcing plate being located within the first groove; along the first direction, the two ends of the reinforcing plate are respectively connected to the outer plate and the inner plate.

[0024] This application embodiment uses a reinforcing plate to connect the outer and inner plates, thereby further strengthening the connection area between the outer and inner plates and improving the strength of the front crossbeam assembly of the roof.

[0025] In one possible implementation of this application, the reinforcing plate includes:

[0026] First reinforcing plate;

[0027] Two adapter plates are respectively located on both sides of the first reinforcing plate along the second direction;

[0028] Two second reinforcing plates are respectively connected to the two adapter plates;

[0029] The first reinforcing plate is connected to the inner plate, and both second reinforcing plates are connected to the outer plate.

[0030] In this embodiment of the application, the reinforcing plate is connected to the inner plate through a first reinforcing plate, and to the outer plate through two second reinforcing plates. The first and second reinforcing plates are connected through an adapter plate. Thus, the inner plate and the outer plate can be connected as one unit by the reinforcing plate, increasing the connection area between the inner plate and the outer plate, which is beneficial to improving the strength of the front crossbeam assembly of the top cover.

[0031] In one possible implementation of this application, the second reinforcing plate is provided with a second through hole, and the outer plate is provided with a third through hole, the second through hole corresponding to the third through hole;

[0032] The inner plate is also provided with process holes, which correspond to the second through hole.

[0033] This embodiment of the application provides a second through hole on the second reinforcing plate, a corresponding third through hole on the outer plate, and a process hole on the inner plate. This facilitates the connection and fixation of fasteners to the lidar by passing them through the second and third through holes, which helps to ensure the connection stability of the lidar and improves assembly efficiency.

[0034] In one possible implementation of this application, the inner plate is further provided with a third flange at both ends along the second direction, and the reinforcing plate is further provided with a fourth flange at both ends along the second direction.

[0035] It also includes two side panel assemblies. Along the second direction, the two side panel assemblies are respectively located at both ends of the front crossbeam of the top cover. The side panel assembly includes an upper side beam, a support plate, a first upper side beam reinforcing plate, and a second upper side beam reinforcing plate. The support plate, the first upper side beam reinforcing plate, and the second upper side beam reinforcing plate are all located on the side of the upper side beam facing the front crossbeam of the top cover. Along the first direction, the support plate is spaced apart from the first upper side beam reinforcing plate and the second upper side beam reinforcing plate. The support plate is connected to the bottom plate of the inner panel. The third flange overlaps on the first upper side beam reinforcing plate and is connected to the first upper side beam reinforcing plate. The fourth flange overlaps on the second upper side beam reinforcing plate and is connected to the second upper side beam reinforcing plate.

[0036] In this embodiment, the inner panel is connected to the first upper beam reinforcing plate of the side panel assembly via the third flange, and to the second upper beam reinforcing plate of the side panel assembly via the fourth flange of the reinforcing plate. The inner panel is also connected to the support plate of the side panel assembly. This increases the connection area between the front crossbeam of the roof and the side panel assembly in the second direction Y and the third direction, which is beneficial to improving the connection strength between the front crossbeam of the roof and the side panel assembly.

[0037] This application also provides a vehicle including the roof front crossbeam assembly as described above.

[0038] The vehicle in this embodiment of the application uses the aforementioned front crossbeam assembly of the roof, thus increasing the strength of the front crossbeam assembly of the roof, thereby reducing the risk of deformation and bending during a collision and improving driving safety.

[0064] As described in the background section, in related technologies, the front crossbeam of the roof consists only of an outer plate and an inner plate arranged opposite each other, which together form a cavity to improve the strength of the front crossbeam and absorb the impact force during a collision. However, the overall strength of the front crossbeam assembly in the related technologies is relatively low, making it prone to deformation and bending when a vehicle collides, thus affecting driving safety.

[0065] In view of this, the present application aims to provide a roof front crossbeam assembly and a vehicle. By adding a reinforcing plate to one side of the inner panel and providing a first groove on the inner panel and a second groove on the reinforcing plate, the outer panel and the inner panel form a first cavity, and the outer panel and the reinforcing plate form a second cavity. Compared with related technologies, the present application's embodiment improves the strength of the roof front crossbeam assembly, thereby reducing the risk of deformation and bending during a collision and improving driving safety.

[0066] The embodiments of this application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. It should be noted that in the embodiments of this application, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. The first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. The first direction X can be, for example, the height direction of the vehicle, the second direction Y can be, for example, the width direction of the vehicle, and the third direction Z can be, for example, the length direction of the vehicle.

[0067] This application provides a roof front crossbeam assembly and a vehicle for improving vehicle body strength. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, vehicles are equipped with wheels and a body. A roof front crossbeam is located on the front side of the roof, connecting to the side panel assembly and the roof body, serving multiple functions such as supporting the roof, enhancing vehicle body strength, dispersing collision energy, and supporting electrical components and trim.

[0068] Please refer to Figures 1-7 This application provides a roof front crossbeam assembly, including: a roof front crossbeam 10, which can be made of metal materials, such as steel, and the size of the roof front crossbeam 10 can be set based on the overall size of the vehicle body.

[0069] The front crossbeam 10 of the roof includes:

[0070] Outer panel 100 is a panel that is exposed on one side of the vehicle body surface.

[0071] An inner panel 200 is disposed opposite to an outer panel 100 along a first direction X. A first groove 210 is provided on the side of the inner panel 200 facing the outer panel 100, and the first groove 210 is disposed along a second direction Y. For example, the first groove 210 can be formed on the inner panel 200 by a process such as stamping.

[0072] A reinforcing plate 300 is connected to the inner plate 200 and is located on the side of the inner plate 200 along a third direction Z, for example, on the side of the inner plate 200 away from the forward nacelle. A second groove 310 is provided on the side of the reinforcing plate 300 facing the outer plate 100, and the second groove 310 is provided along a second direction Y. Exemplarily, the second groove 310 can be formed on the reinforcing plate 300 by a process such as stamping.

[0073] like Figure 6 As shown, in this embodiment, the outer plate 100 covers the inner plate 200 and the reinforcing plate 300. The periphery of the outer plate 100, the periphery of the inner plate 200, and the periphery of the reinforcing plate 300 can be connected and fixed by welding, bonding, or other methods. The first groove 210 of the outer plate 100 and the inner plate 200 together form a first cavity 410, and the second groove 310 of the outer plate 100 and the reinforcing plate 300 together form a second cavity 420.

[0074] With the above structure, two independent cavities (including a first cavity 410 and a second cavity 420) are formed inside the front crossbeam 10 of the top cover in this embodiment of the application. Figure 1 As shown, when the side of the vehicle collides with the side impact pillar 30, the first cavity 410 and the second cavity 420 can form two force transmission paths, thereby reducing the force applied to each force transmission path. This can improve the strength of the front crossbeam assembly of the roof, thereby reducing the risk of deformation and bending during a collision and improving driving safety.

[0075] This embodiment of the application adds a reinforcing plate 300 to one side of the inner plate 200, and provides a first groove 210 on the inner plate 200 and a second groove 310 on the reinforcing plate 300, so that the outer plate 100 and the inner plate 200 form a first cavity 410, and the outer plate 100 and the reinforcing plate 700 form a second cavity 420. Compared with the solutions of related technologies, this embodiment of the application improves the strength of the front crossbeam assembly of the roof, thereby reducing the risk of deformation and bending during a collision and improving driving safety.

[0076] Please continue to refer to Figure 2 and Figure 3The inner panel 200 of this embodiment includes an inner panel bottom plate 201 and a plurality of inner panel sidewalls, which are connected end-to-end and all connected to the inner panel bottom plate 201. For example, the plurality of inner panel sidewalls include a first inner panel sidewall 202 and a third inner panel sidewall 204 perpendicular to a third direction Z, and a second inner panel sidewall 203 and a fourth inner panel sidewall 205 perpendicular to a second direction Y. The first inner panel sidewall 202, the second inner panel sidewall 203, the third inner panel sidewall 204, and the fourth inner panel sidewall 205 are connected end-to-end, and together with the inner panel bottom plate 201, they form the aforementioned first groove 210. Along the first direction X, the side wall 202 of the first inner plate is provided with a first flange 220 on the side opposite to the bottom plate 201 of the inner plate; along the third direction Z, the first flange 220 is provided opposite to the first groove 210.

[0077] The reinforcing plate 300 includes a reinforcing plate base plate 301 and multiple reinforcing plate sidewalls, which are connected end-to-end and all connected to the reinforcing plate base plate 301. For example, the multiple reinforcing plate sidewalls include a first reinforcing plate sidewall 302 and a third reinforcing plate sidewall 304 perpendicular to the third direction Z, and a second reinforcing plate sidewall 303 and a fourth reinforcing plate sidewall 305 perpendicular to the second direction Y. The first reinforcing plate sidewall 302 is disposed close to the first inner plate sidewall 202. The first reinforcing plate sidewall 302, the second reinforcing plate sidewall 303, the third reinforcing plate sidewall 304, and the fourth reinforcing plate sidewall 305 are connected end-to-end, and together with the reinforcing plate base plate 301, they form the aforementioned second groove 310. Along the first direction X, the side wall 302 of the first reinforcing plate is provided with a second flange 320 on the side opposite to the bottom plate 301 of the reinforcing plate, and along the third direction Z, the second flange 320 is provided opposite to the second groove 310.

[0078] Please continue to refer to Figure 6 In this embodiment, the second flange 320 overlaps and is connected to the first flange 220. Exemplarily, the first flange 220 can be welded to the second flange 320. The outer plate 100 is connected to the second flange 320, multiple inner plate sidewalls, and multiple reinforcing plate sidewalls. That is, the four sides of the outer plate 100 are respectively connected to the second inner plate sidewall 203, the third inner plate sidewall 204, the fourth inner plate sidewall 205, the second reinforcing plate sidewall 303, the third reinforcing plate sidewall 304, and the fourth reinforcing plate sidewall 305, and the middle part of the outer plate 100 is connected to the second flange 320.

[0079] In this embodiment, the reinforcing plate 300 is connected to the first flange 220 of the inner plate 200 via the second flange 320. The outer plate 100 is not only connected to the top of each side wall of the inner plate 200 and the top of each side wall of the reinforcing plate 300, but also connected to the second flange 320, thereby increasing the connection area between the outer plate 100, the inner plate 200 and the reinforcing plate 300, thereby further improving the strength of the front crossbeam assembly of the roof and reducing the risk of deformation and bending during a collision.

[0080] Please continue to refer to Figure 2 Along the first direction X, the outer plate 100 of this application embodiment is provided with a third groove 110 on the side opposite to the inner plate 200, and the third groove 110 can be provided along the second direction Y.

[0081] In this embodiment, by providing a third groove 110 on the side of the outer panel 100 away from the inner panel 200, the deformation and torsion resistance of the outer panel 100 can be greatly improved compared with the near-planar structure in related technologies, thereby helping to further improve the strength of the top cover front crossbeam assembly.

[0082] Please continue to refer to Figure 2 , Figure 4 and Figure 6 The top cover front crossbeam assembly of this application embodiment also includes a mass block 500, which is located within the first groove 210. The weight of the mass block 500 can be determined as needed, and the position of the mass block 500 can also be set as needed, for example, it can be located in the middle of the inner plate 200.

[0083] By setting the mass block 500 in this embodiment, the overall weight of the front crossbeam assembly of the roof can be increased, which helps to reduce noise and vibration inside the vehicle; the setting of the mass block 500 also helps to further improve the strength of the front crossbeam assembly of the roof, and improve the driving stability and safety of the vehicle.

[0084] To facilitate the connection between the mass block 500 and the inner plate 200, this embodiment of the application provides a plurality of first through holes 230 on the inner plate bottom plate 201 of the inner plate 200, and a plurality of first fixing holes 510 on the mass block 500. The first fastener 610 passes through the first through hole 230 and is connected to the corresponding first fixing hole 510.

[0085] The first fixing hole 510 in this embodiment can be a threaded hole, and the first fastener 610 can be a screw, bolt, etc. The first fastener 610 passes through the first through hole 230 on the inner plate 200 and is assembled and fixed with the first fixing hole 510 on the mass block 500, which is beneficial to improve the assembly efficiency of the mass block 500 and facilitates subsequent maintenance and disassembly.

[0086] Please continue to refer to Figure 2 , Figure 4and Figure 6 The top cover front crossbeam assembly of this application embodiment also includes a reinforcing plate 700, which is located within the first groove 210. Along the first direction X, the two ends of the reinforcing plate 700 are respectively connected to the outer plate 100 and the inner plate 200.

[0087] In this embodiment of the application, a reinforcing plate 700 is provided to connect the outer plate 100 and the inner plate 200, thereby further strengthening the connection area between the outer plate 100 and the inner plate 200, which is beneficial to improving the strength of the front crossbeam assembly of the top cover.

[0088] Specifically, the reinforcement plate 700 includes:

[0089] The first reinforcing plate 710 is connected to the inner plate 200, for example, by welding.

[0090] Two adapter plates 720 are located on both sides of the first reinforcing plate 710 along the second direction Y.

[0091] Two second reinforcing plates 730 are connected to two adapter plates 720 respectively, and both second reinforcing plates 730 are connected to the outer plate 100. For example, the second reinforcing plates 730 and the outer plate 100 can be connected by welding.

[0092] In this embodiment, the reinforcing plate 700 is connected to the inner plate 200 through a first reinforcing plate 710, and to the outer plate 100 through two second reinforcing plates 730. The first reinforcing plate 710 and the second reinforcing plate 730 are connected through a transition plate 720. Thus, the inner plate 200 and the outer plate 100 can be connected as a whole by the reinforcing plate 700, increasing the connection area between the inner plate 200 and the outer plate 100, which is beneficial to improving the strength of the front crossbeam assembly of the top cover.

[0093] Please continue to refer to Figure 2 and Figure 4 In this embodiment, the second reinforcing plate 730 has a second through hole 731, and the outer plate 100 has a third through hole 120, with the second through hole 731 corresponding to the third through hole 120. The inner plate 200 also has a process hole 240, which corresponds to the second through hole 731. During assembly, the reinforcing plate 700 can be welded to the outer plate 100 and the inner plate 200 through the process hole 240, and fasteners can be passed through the second through hole 731 and the third through hole 120 and then connected and fixed to the lidar.

[0094] In this embodiment, a second through hole 731 is provided on the second reinforcing plate 730, a corresponding third through hole 120 is provided on the outer plate 100, and a process hole 240 is provided on the inner plate 200. This facilitates the fasteners to pass through the second through hole 731 and the third through hole 120 and then be connected and fixed to the lidar through the process hole 240, which helps to ensure the connection stability of the lidar and improve assembly efficiency.

[0095] Please continue to refer to Figure 2 , Figure 3 and Figure 7 In this embodiment of the application, the inner plate 200 is provided with a third flange 250 at both ends along the second direction Y, and the reinforcing plate 300 is provided with a fourth flange 330 at both ends along the second direction Y.

[0096] The front crossbeam assembly also includes two side panel assemblies 20, located at both ends of the front crossbeam 10 along the second direction Y. Each side panel assembly 20 includes an upper beam 21, a support plate 22, a first upper beam reinforcing plate 23, and a second upper beam reinforcing plate 24. The support plate 22, the first upper beam reinforcing plate 23, and the second upper beam reinforcing plate 24 are all located on the side of the upper beam 21 facing the front crossbeam 10. Furthermore, along the first direction X, the support plate 22 is spaced apart from the first upper beam reinforcing plate 23 and the second upper beam reinforcing plate 24.

[0097] The support plate 22 is connected to the inner bottom plate 201. For example, the support plate 22 may have two spaced-apart fourth through holes 221, and the inner bottom plate 201 may have two corresponding projection-welded nuts 260. A second fastener 620 (e.g., a bolt) passes through the fourth through holes 221 and is threadedly connected to the corresponding projection-welded nut 260. The support plate 22 may also be welded to the inner bottom plate 201 around its perimeter to improve the stability of the connection.

[0098] The third flange 250 overlaps the first upper beam reinforcing plate 23 and is connected to the first upper beam reinforcing plate 23. For example, as shown... Figure 7 As shown, the first upper beam reinforcing plate 23 can extend from the inside of the upper beam 21, thereby increasing the strength of the upper beam 21. The third flange 250 is attached to the first upper beam reinforcing plate 23 and then fixed by welding.

[0099] The fourth flange 330 overlaps and connects to the second upper beam reinforcing plate 24. Exemplarily, the second upper beam reinforcing plate 24 can also extend from the interior of the upper beam 21, thereby increasing the strength of the upper beam 21. After the fourth flange 330 overlaps the second upper beam reinforcing plate 24, it can be fixed by welding.

[0100] In this embodiment, the inner plate 200 is connected to the first upper beam reinforcing plate 23 of the side wall assembly 20 via the third flange 250, and to the second upper beam reinforcing plate 24 of the side wall assembly 20 via the fourth flange 330 of the reinforcing plate 300. The inner plate 200 is also connected to the support plate 22 of the side wall assembly 20. This increases the connection area between the front crossbeam 10 of the top cover and the side wall assembly 20 in the second direction Y and the third direction Z, which is beneficial to improving the connection strength between the front crossbeam 10 of the top cover and the side wall assembly 20.

[0101] This application also provides a vehicle including the aforementioned roof front crossbeam assembly.

[0102] The vehicle in this embodiment of the application uses the aforementioned front crossbeam assembly of the roof, thus increasing the strength of the front crossbeam assembly of the roof, thereby reducing the risk of deformation and bending during a collision and improving driving safety.
