[0033] Hereinafter, with reference to the accompanying drawings, a roof front cross beam structure 100 according to an embodiment of the present utility model will be described.

[0034] like Figure 1-Figure 3 As shown, the front crossbeam structure 100 of the top cover includes an upper crossbeam plate 1 and a lower crossbeam plate 2. The upper crossbeam plate 1 is formed with a first mounting portion 11, and the first mounting portion 11 is used to mount the radar assembly. The lower crossbeam plate 2 is arranged on one side of the upper crossbeam plate 1 in the thickness direction. Then, the two sides of the upper crossbeam plate 1 in the thickness direction are respectively a first side and a second side. The lower crossbeam plate 2 can be arranged on the first side of the upper crossbeam plate 1, or, the lower crossbeam plate 2 can be arranged on the second side of the lower crossbeam plate 2; the lower crossbeam plate 2 is fixedly connected to the upper crossbeam plate 1, and the lower crossbeam plate 2 is formed with a second mounting portion 21, and the second mounting portion 21 is used to mount the airbag assembly.

[0035] Among them, in the length direction of the front cross beam structure 100 of the top cover, the first mounting portion 11 and the second mounting portion 21 are staggered. Then, on any plane parallel to the length direction of the front cross beam structure 100 of the top cover, the orthographic projection of the first mounting portion 11 will not be entirely located within the orthographic projection range of the second mounting portion 21, and the orthographic projection of the second mounting portion 21 will not be entirely located within the orthographic projection range of the first mounting portion 11; in other words, on any plane parallel to the length direction of the front cross beam structure 100 of the top cover, the orthographic projection of the first mounting portion 11 can be spaced apart from the orthographic projection of the second mounting portion 21, or a portion of the orthographic projection of the first mounting portion 11 overlaps with a portion of the orthographic projection of the second mounting portion 21.

[0036] It can be seen that in the embodiment of the present application, the front cross beam structure 100 of the roof includes an upper cross beam plate 1 and a lower cross beam plate 2 which are stacked and fixedly connected along the thickness direction of the upper cross beam plate 1, which can improve the structural strength, bending stiffness and torsional stiffness of the front cross beam structure 100 of the roof, thereby improving the bearing capacity of the front cross beam structure 100 of the roof, so as to lay a good foundation for providing a reliable installation position for other components of the front cross beam structure 100 of the roof; at the same time, the upper cross beam plate 1 can provide a mounting position for the radar assembly to realize the installation of the radar assembly, which is convenient for bringing the radar assembly close to the external environment of the vehicle 300, and is conducive to using a smaller number of radar assemblies to achieve a larger detection range, and the upper cross beam plate 1 and the lower cross beam plate 2 are not easy to affect the detection of the radar assembly, which is conducive to improving the detection reliability of the radar assembly. , and the lower plate 2 of the crossbeam can provide an installation position for the airbag assembly to realize the installation of the airbag assembly, which is convenient for making the airbag assembly close to the internal environment of the vehicle 300. The upper plate 1 of the crossbeam and the lower plate 2 of the crossbeam are not likely to affect the deployment of the airbag assembly, so that the airbag assembly can provide good safety protection for the occupants in the vehicle; and, since the first mounting portion 11 and the second mounting portion 21 are staggered in the length direction of the top cover front crossbeam structure 100, it is convenient for the radar assembly and the airbag assembly to be staggered in the length direction of the top cover front crossbeam structure 100, so that the distribution of the radar assembly and the airbag assembly is relatively dispersed, which is convenient for reducing the influence between the radar assembly and the airbag assembly, and it is not easy to affect the radar assembly even after the airbag assembly is deployed.

[0037] Obviously, installing the airbag assembly on the lower plate 2 of the crossbeam in the vehicle 300 is conducive to freeing up more space for components at the dashboard of the vehicle 300, and the components at the dashboard are not likely to restrict the installation and deployment of the airbag assembly.

[0038] Exemplarily, the thickness direction of the crossbeam upper plate 1 is the up-down direction, the length direction of the roof front crossbeam structure 100 is the left-right direction, the width direction of the roof front crossbeam structure 100 is the front-back direction, the crossbeam lower plate 2 is arranged on the lower side of the crossbeam upper plate 1, and the first mounting portion 11 and the second mounting portion 21 are staggered along the left-right direction. For example, the first mounting portion 11 is located in the middle of the crossbeam upper plate 1 in the left-right direction, and the second mounting portion 21 is located in the left or right part of the crossbeam lower plate 2 in the left-right direction.

[0039] The airbag assembly is mainly used to prevent the collision between the occupants and the internal parts of the vehicle when the vehicle 300 collides; when the front cross beam structure 100 of the roof is used for the vehicle 300, if the vehicle 300 has a main driver's seat and a co-driver's seat, the airbag assembly in the embodiment of the present application may include a main driver's airbag and / or a co-driver's airbag. In the description of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the related objects before and after are in an "or" relationship.

[0040] The radar can have at least one of the following functions: perceiving the environment (for example, after the radar is turned on, the environment around the vehicle can be presented in the form of a laser scanning 3D model, and the algorithm can also be used to compare the changes between the previous and next frames, and then compare the surrounding environment), assisting the car in planning the route (it can independently plan the driving route and control the vehicle to reach the predetermined target; for example, the turning time after the signal encounters an obstacle is used to measure the distance between the target and the vehicle itself, and then it can also assist the vehicle in identifying the system street), assisting driving safety (achieving redundancy and improving safety; for example, when the visual effect is affected by strong light and the perception ability is affected, the radar will escort the assisted driving), and detailed positioning (for example, the radar can realize synchronous mapping to obtain the global map in real time during driving, thereby improving navigation accuracy and speed); for example, the radar can be selected as a laser radar, but is not limited to this.

[0041] According to the roof front cross beam structure 100 of the embodiment of the utility model, the roof front cross beam structure 100 includes an upper cross beam plate 1 and a lower cross beam plate 2 to improve the bearing capacity of the roof front cross beam structure 100, so as to lay a good foundation for the roof front cross beam structure 100 to provide a reliable installation position for other components; at the same time, a first installation portion 11 is formed on the upper cross beam plate 1 for installing the radar assembly, and a second installation portion 21 is formed on the lower cross beam plate 2 for installing the airbag assembly, and the first installation portion 11 and the second installation portion 21 are staggered in the length direction of the roof front cross beam structure 100, so that the roof front cross beam structure 100 can realize the integrated installation of the radar assembly and the airbag assembly, and reduce the constraints and restrictions on the airbag assembly, improve the collision safety, and thus achieve the maximum compatibility of performance and function.

[0042] It should be noted that in the embodiment of the present application, there is no specific restriction on the specific structural form of the first mounting portion 11 and the second mounting portion 21, that is, there is no specific restriction on the connection mode between the first mounting portion 11 and the radar assembly, and the connection mode between the second mounting portion 21 and the airbag assembly. Exemplarily, the first mounting portion 11 is formed with a plurality of spaced first mounting holes 111, and fasteners are inserted through the first mounting holes 111 to achieve the fixation of the radar assembly and the upper plate 1 of the crossbeam; or the first mounting portion 11 is configured as a plate-like structure. The second mounting portion 21 is formed with a plurality of spaced second mounting holes 211, and fasteners (such as bolts, etc.) are inserted through the second mounting holes 211 to achieve the fixation of the airbag assembly and the lower plate 2 of the crossbeam; or the second mounting portion 21 is configured as a plate-like structure.

[0043] In some embodiments, Figure 1 and Figure 3 As shown, the upper crossbeam plate 1 is formed with a first mounting groove 1a recessed toward the lower crossbeam plate 2, the first mounting groove 1a is used to accommodate at least part of the radar assembly, and the groove wall of the first mounting groove 1a defines a first mounting portion 11, so as to reduce the height of the radar assembly protruding toward the side of the upper crossbeam plate 1 away from the lower crossbeam plate 2 under the premise of realizing reliable installation of the radar assembly, and even facilitate the radar assembly not to protrude toward the side of the upper crossbeam plate 1 away from the lower crossbeam plate 2, and at the same time, the first mounting groove 1a can strengthen the upper crossbeam plate 1 to a certain extent; and / or, The crossbeam lower plate 2 is formed with a second mounting groove 2a recessed toward the crossbeam upper plate 1, the second mounting groove 2a is used to accommodate at least part of the airbag assembly, and the groove wall of the second mounting groove 2a defines a second mounting portion 21, so as to reduce the height of the airbag assembly protruding toward the side of the crossbeam lower plate 2 away from the crossbeam upper plate 1 under the premise of achieving reliable installation of the airbag assembly, and even facilitate the airbag assembly not protruding toward the side of the crossbeam lower plate 2 away from the crossbeam upper plate 1, and at the same time, the second mounting groove 2a can strengthen the crossbeam lower plate 2 to a certain extent.

[0044] In addition, the airbag assembly is installed on the lower plate 2 of the crossbeam, so that when the front crossbeam structure 100 of the roof is used in the vehicle 300, the airbag assembly is basically located on the upper side of the driver and passengers. The larger volume of the airbag assembly can better achieve cushioning, and the setting of the second installation groove 2a is convenient for meeting the layout requirements of the larger volume of the airbag assembly.

[0045] Exemplarily, the crossbeam upper plate 1 is formed with a downwardly recessed first mounting groove 1a, the groove bottom wall and / or groove side wall of the first mounting groove 1a defines a first mounting portion 11, and the crossbeam lower plate 2 is formed with an upwardly recessed second mounting groove 2a, the groove bottom wall and / or groove side wall of the second mounting groove 2a defines a second mounting portion 21.

[0046] In some embodiments, Figure 1 , Figure 3 and Figure 4 As shown, the upper crossbeam plate 1 is formed with two first connection parts 12 and a second connection part 13, which are respectively fixedly connected to the lower crossbeam plate 2, and the two first connection parts 12 are respectively located at the two ends of the upper crossbeam plate 1 in the width direction of the roof front crossbeam structure 100, and the second connection part 13 is arranged between the two first connection parts 12. Therefore, it is convenient to improve the connection strength between the upper crossbeam plate 1 and the lower crossbeam plate 2, which is conducive to further improving the bearing capacity of the roof front crossbeam structure 100.

[0047] Among them, a part of the second connecting portion 13 is fixedly connected to the second mounting portion 21, and the above-mentioned part of the second connecting portion 13 can play a certain supporting role on the second mounting portion 21, so as to improve the load-bearing capacity of the front cross beam structure 100 of the top cover at the position of the second mounting portion 21, thereby helping to improve the safety and reliability of the airbag assembly.

[0048] In the above technical solution, there is no specific limitation on the fixed connection method between a part of the second connection portion 13 and the second mounting portion 21 ; illustratively, a part of the second connection portion 13 is fixed to the second mounting portion 21 by welding.

[0049] For example, in Figure 1 , Figure 3 and Figure 4In the example, the crossbeam upper plate 1 is formed with two first connection portions 12 and a second connection portion 13, the two first connection portions 12 are respectively located at the front and rear ends of the crossbeam upper plate 1, the second connection portion 13 is adjacent to the middle position of the crossbeam upper plate 1 in the front and rear direction, and the first connection portion 12 and the second connection portion 13 are respectively spaced apart from the first mounting portion 11; the crossbeam lower plate 2 is formed with a second mounting groove 2a which is recessed upward, the second mounting groove 2a is used to accommodate at least part of the airbag assembly, the groove wall of the second mounting groove 2a defines a second mounting portion 21, a portion of the second connection portion 13 is fixedly connected to the groove bottom wall of the second mounting groove 2a, and another portion of the second connection portion 13 is fixedly connected to the groove side wall of the second mounting groove 2a, thereby improving the structural stability and structural bearing capacity of the second mounting groove 2a.

[0050] In some embodiments, Figure 3-Figure 5 As shown, a reinforcing portion 14 is formed on the crossbeam upper plate 1, and the reinforcing portion 14 is spaced apart from the first mounting portion 11, thereby improving the structural strength of the crossbeam upper plate 1 and the bearing capacity of the crossbeam upper plate 1, which is beneficial to improving the installation reliability of the radar assembly, and the reinforcing portion 14 is not easy to interfere with the installation of the radar assembly.

[0051] The reinforcing portion 14 includes a first reinforcing portion 141. The first mounting portion 11 is provided with the first reinforcing portion 141 on at least one of the two sides in the length direction of the top cover front cross beam structure 100. The first reinforcing portion 141 includes a first reinforcing rib 141a and a second reinforcing rib 141b arranged crosswise. The first reinforcing rib 141a extends along the length direction of the top cover front cross beam structure 100, and the second reinforcing rib 141b extends along the width direction of the top cover front cross beam structure 100. The first reinforcing portion 141 can enhance the structural strength and torsion resistance of the cross beam upper plate 1 in multiple directions, and the first reinforcing portion 141 has a simple structure and is easy to process. And / or, the reinforcement portion 14 includes a second reinforcement portion 142, and the first mounting portion 11 is provided with a second reinforcement portion 142 on at least one side of the two sides in the width direction of the front cross beam structure 100 of the top cover, and the second reinforcement portion 142 includes at least one third reinforcement rib 142a, and the third reinforcement rib 142a includes a plurality of recesses 142b and a plurality of protrusions 142c, and the plurality of recesses 142b and the plurality of protrusions 142c are alternately arranged one by one along the length direction of the front cross beam of the top cover. The second reinforcement portion 142 can also enhance the structural strength and torsional resistance of the cross beam upper plate 1 in multiple directions, and the second reinforcement portion 142 has a simple structure and is easy to process.

[0052] It should be noted that, in the embodiment of the present application, the "recess 142b" and the "convex portion 142c" can be understood as relative concepts. If the side protruding toward the first mounting portion 11 on the width of the front cross beam structure 100 of the top cover is the convex portion 142c, then the side protruding toward the side away from the first mounting portion 11 on the width direction of the front cross beam structure 100 of the top cover is the recess 142b; or, if the side protruding toward the first mounting portion 11 on the width of the front cross beam structure 100 of the top cover is the recess 142b, then the side protruding toward the side away from the first mounting portion 11 on the width direction of the front cross beam structure 100 of the top cover is the convex portion 142c.

[0053] It can be understood that in the embodiment of the present application, the reinforcing ribs (the first reinforcing rib 141a, the second reinforcing rib 141b, and the second reinforcing rib 141b described above) can be convex ribs formed on the upper plate 1 of the beam and protruding toward the side away from the lower plate 2 of the beam, or can be grooves formed on the upper plate 1 of the beam and concave toward the side close to the lower plate 2 of the beam.

The third reinforcing rib 142a extends in the left-right direction into a long strip shape and includes a plurality of convex portions 142c protruding forward and a plurality of concave portions 142b concave backward. The convex portions 142c and the concave portions 142b are respectively roughly formed into an arc shape, so that the third reinforcing rib 142a is roughly formed into a wave shape. The first reinforcement portion 141 and the second reinforcement portion 142 are disposed adjacent to the periphery of the first mounting portion 11 so as to enhance the bearing capacity of the periphery of the first mounting portion 11 .
