The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0040] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0041] See also Figures 1 to 3 This embodiment provides a beam connection structure 100 for a vehicle 200 (see attached Fig. 9), the beam connection structure 100 includes a first beam body 10, a second beam body 20, a first connecting member 30 and a second connecting member 40. The length direction of the first beam body 10 intersects with the length direction of the second beam body 20. The first connecting member 30 is provided with a mounting hole 31, and the end of the first beam body 10 fits in the mounting hole 31 and is connected to the first connecting member 30. One side of the second connecting member 40 is connected to the first connecting member 30, and the other side of the second connecting member 40 is connected to the second beam body 20.

[0042] In this embodiment, the first beam body 10 can be a cross beam, and the second beam body 20 can be a longitudinal beam. The first beam body 10 is assembled in the mounting hole 31 of the first connecting member 30 and connected to the first connecting member 30. Compared with the existing solution that the cross beam is simply fixed to the longitudinal beam by angle steel, the first connecting member 30 with the mounting hole 31 cooperates with the first beam body 10. When the beam connection structure 100 is impacted, the structural design of the mounting hole 31 can play a role in buffering, shock absorption and energy absorption, ensuring the connection reliability between the first beam body 10 and the first connecting member 30, and the first connecting member 30 as a whole defines the mounting hole 31, further ensuring the overall strength of the first connecting member 30, thereby improving the connection strength between the first beam body 10 and the first connecting member 30. The first connecting member 30 is then connected to the second beam body 20 through the second connecting member 40, which can ensure the connection reliability between the first beam body 10 and the second beam body 20 through the first connecting member 30 and the second connecting member 40. Therefore, the beam connection structure 100 of this embodiment can improve the connection stability between the first beam body 10 and the second beam body 20.

[0043] In this embodiment, see Figure 2 The first beam body 10 is made of extruded aluminum profiles. The first beam body 10 includes four first side walls 11. The four first side walls 11 sequentially form a rectangular frame, wherein two first side walls 11 are arranged at intervals along the first direction Z, and the other two first side walls 11 are arranged at intervals along the second direction X. Optionally, the first beam body 10 also includes a connecting wall 12, which is arranged between the two first side walls 11 along the first direction Z, and the two ends of the connecting wall 12 along the second direction X are respectively connected to the other two first side walls 11. Extruded aluminum profiles can reduce the overall weight of the first beam body 10 and further reduce the overall weight of the vehicle 200. When the vehicle 200 is a gasoline vehicle, it can further improve fuel economy and reduce emissions. When the vehicle 200 is a pure electric vehicle, it can further improve the endurance of the pure electric vehicle. In addition, extruded aluminum profiles also have lower production and processing costs, which is conducive to reducing the cost of the beam connection structure 100. At the same time, the structural design of the four first side walls 11 and the connecting wall 12 can improve the structural stability of the first beam body 10 and ensure the overall strength of the first beam body 10 .

[0044] Alternatively, see Figure 2, two first side walls 11 arranged opposite to each other along the second direction X are respectively provided with two inwardly concave grooves 13, and the two grooves 13 located on the same first side wall 11 are arranged on both sides of the connecting wall 12 along the first direction Z. Figure 4 The two grooves 13 are sunken inward to form reinforcing ribs, thereby reinforcing the first beam body 10 and saving external space.

[0045] In this embodiment, see Figure 1 , the second beam body 20 is made of extruded aluminum profile, and the second beam body 20 includes four second side walls 21, and the four second side walls 21 are sequentially surrounded by a rectangular frame. The extruded aluminum profile can reduce the overall weight of the second beam body 20, and further reduce the overall weight of the vehicle 200. When the vehicle 200 is a fuel vehicle, the fuel economy can be further improved and emissions can be reduced. When the vehicle 200 is a pure electric vehicle, the endurance of the pure electric vehicle can be further improved. In addition, the extruded aluminum profile also has a lower production and processing cost, which is conducive to reducing the cost of the beam connection structure 100. At the same time, the structural design of the four second side walls 21 can improve the structural stability of the second beam body 20 and ensure the overall strength of the second beam body 20. In other embodiments, other components can be additionally provided in the second beam body 20 according to actual needs.

[0046] In this embodiment, see Figure 3 and Figure 4 The first connecting member 30 includes a first side wall 32, a second side wall 33 and two third side walls 34, the two third side walls 34 are arranged at intervals along the first direction Z, the first side wall 32 and the second side wall 33 are arranged at intervals along the second direction X, the two ends of the first side wall 32 along the first direction Z are respectively connected to the two third side walls 34, the two ends of the second side wall 33 along the first direction Z are respectively connected to the two third side walls 34, the first side wall 32, the second side wall 33 and the two third side walls 34 surround the mounting hole 31, and the second connecting member 40 is connected to the third side wall 34.

[0047] The structure with the mounting hole 31 formed by the first side wall 32, the second side wall 33 and the two third side walls 34 has high structural stability, which can improve the connection reliability between the first beam body 10 and the first connecting member 30. At the same time, the third side wall 34 also facilitates the fixed connection between the second connecting member 40 and the first connecting member 30. In other embodiments, the second connecting member 40 can also be fixedly connected to the first side wall 32 and / or the second side wall 33.

[0048] Specifically, the first connecting member 30 may be made of an extruded aluminum profile, which has low production and processing costs.

[0049] In this embodiment, see Figure 4 and Figure 5The first connecting member 30 also includes a fourth side wall 35. Along the second direction X, the fourth side wall 35 is arranged on the side of the first side wall 32 away from the second side wall 33. The two ends of the fourth side wall 35 along the first direction Z are respectively connected to the two third side walls 34. The fourth side wall 35, the first side wall 32 and the two third side walls 34 are connected to form a rectangular tube structure 36.

[0050] In this way, the rectangular tube structure 36 can play the role of transferring loads and reducing vibration and absorbing energy, and improve the anti-collision performance of the beam connection structure 100.

[0051] Alternatively, see Figure 5 The first connecting member 30 includes two fourth side walls 35, the two fourth side walls 35 are spaced apart along the second direction X, and the first side wall 32 and the second side wall 33 are arranged between the two fourth side walls 35. The first connecting member 30 includes two rectangular tube structures 36. One rectangular tube structure 36 is composed of Figure 5 The right sides of the two third side walls 34, Figure 5 The fourth side wall 35 and the second side wall 33 on the right side of the middle are together surrounded by another rectangular tube structure 36. Figure 5 The left sides of the two third side walls 34, Figure 5 The fourth side wall 35 on the left side of the middle and the first side wall 32 are together formed. In this way, the overall strength of the first connecting member 30 can be further enhanced, so that the first connecting member 30 can have a better vibration reduction and energy absorption effect when subjected to forces in different directions.

[0052] In this embodiment, see Figure 4 The first connecting member 30 further includes a reinforcing wall 37, which extends along the second direction X, and the reinforcing wall 37 is connected between the first side wall 32 and the fourth side wall 35, and / or the reinforcing wall 37 is connected between the second side wall 33 and the fourth side wall 35, and the first fastener 60 passes through the reinforcing wall 37. The reinforcing wall 37 can further strengthen the strength and stability of the rectangular tube structure 36, and improve its energy absorption and vibration reduction effect. When there are two fourth side walls 35, two reinforcing walls 37 can be provided, one reinforcing wall 37 is connected between the first side wall 32 and the fourth side wall 35 adjacent to the first side wall 32, and the other reinforcing wall 37 is connected between the second side wall 33 and the fourth side wall 35 adjacent to the second side wall 33. In other embodiments, a plurality of reinforcing walls 37 can be respectively provided on one side of the first side wall 32 and / or one side of the second side wall 33, and the plurality of reinforcing walls 37 are distributed along the first direction Z to further improve the strength and stability of the rectangular tube structure 36.

[0053] In this embodiment, see Figure 3 and Figure 4There are two second connecting members 40, and the two second connecting members 40 are respectively connected to the two third side walls 34. The beam connection structure 100 also includes a first fastener 60, which is disposed between the first side wall 32 and the fourth side wall 35, passes through the two second connecting members 40 and the two third side walls 34, and fixes the two second connecting members 40 to the two third side walls 34.

[0054] Thus, the two second connectors 40 are reliably fixed to the first connector 30 by the first fastener 60. Meanwhile, the two second connectors 40 can also ensure the reliability of the connection between the first connector 30 on both sides of the first direction Z and the first beam body 10 on both sides of the first direction Z and the longitudinal beam.

[0055] Alternatively, see Figure 4 The first fastener 60 includes a bolt 61 and a nut 62. The bolt 61 passes through the two second connectors 40 and the two third side walls 34, and the head of the bolt 61 abuts against one of the second connectors 40. The other end of the bolt 61 extends from the other second connector 40. The nut 62 is connected to the bolt 61, and one end of the nut 62 passes through the other second connector 40 and abuts against the other third side wall 34. In this way, the reliability of the bolt 61 and the nut 62 jointly fixing the two second connectors 40 to the two third side walls 34 can be improved.

[0056] In other embodiments, the nut 62 may also directly abut against another second connecting member 40, and the reliability of fixing the two second connecting members 40 to the outer sides of the two third side walls 34 can also be achieved through the mutual clamping action of the head of the bolt 61 and the nut 62. In another embodiment, the head of the bolt 61 passes through one of the second connecting members 40 and abuts against the third side wall 34 adjacent to the second connecting member 40, and the nut 62 abuts against the other second connecting member 40.

[0057] In this embodiment, see Figure 4 The first connecting member 30 also includes a sleeve 38, which extends along the first direction Z. The sleeve 38 passes through a second connecting member 40 and a third side wall 34. One end of the sleeve 38 abuts against the second connecting member 40, and the other end of the sleeve 38 abuts against another third side wall 34. The first fastener 60 is disposed in the sleeve 38.

[0058] In the process of the first fastener 60 fixing the two second connectors 40 on both sides of the first connector 30, since the two ends of the sleeve 38 are respectively supported between one second connector 40 and the third side wall 34 connected to the other second connector 40, the fastening force of the first fastener 60 is prevented from bending the third side wall 34 or the second connector 40, thereby ensuring the overall shape integrity of the first connector 30.

[0059] In other embodiments, both ends of the sleeve 38 may also abut against the two third side walls 34 respectively, and the sleeve 38 may be installed into the first connecting member 30 from the end of the rectangular tube structure 36 .

[0060] Alternatively, see Figure 4 and Figure 5 , one of the two third side walls 34 is provided with a first opening 391, the reinforcing wall 37 is provided with a second opening 392, and the other third side wall 34 is provided with a third opening 393. Among them, the inner diameter of the first opening 391 is greater than or equal to the outer diameter of the sleeve 38, the inner diameter of the second opening 392 is greater than or equal to the outer diameter of the sleeve 38, and the inner diameter of the third opening 393 is less than or equal to the outer diameter of the sleeve 38. In the process of installing the sleeve 38 and the second connecting member 40 on the first connecting member 30, the sleeve 38 is first installed into the first connecting member 30 from the first opening 391, so that the sleeve 38 passes through the second opening 392 and abuts against the third side wall 34 provided with the third opening 393, and then the two second connecting members 40 are respectively stacked on the two third side walls 34, and finally the two second connecting members 40 are locked on the two third side walls 34 by the first fastener 60.

[0061] Optionally, the inner diameter of the first opening 391 is approximately 0.5 mm larger than the outer diameter of the sleeve 38, and the inner diameter of the third opening 393 is approximately 2 mm larger than the outer diameter of the first fastener 60. In other embodiments, the specific outer diameters of the first opening 391, the second opening 392 and the third opening 393 can be adjusted according to actual needs.

[0062] In this embodiment, see Figure 6 and Figure 7 The second connecting member 40 includes a first plate body 41 and a second plate body 42 connected to each other. The first plate body 41 is stacked on the first connecting member 30 and connected to the first connecting member 30 . The second plate body 42 is stacked on the second side wall 21 of the second beam body 20 and connected to the second beam body 20 .

[0063] In this way, the first connecting member 30 is fixed by the first plate body 41 , and the second plate body 42 is fixedly connected to the second beam body 20 , so that the second connecting member 40 can be firmly connected with the first connecting member 30 and the second beam body 20 .

[0064] Optionally, the second plate body 42 is connected to the second beam body 20 via second fasteners 70 , and the number and arrangement of the second fasteners 70 can be adjusted according to actual needs.

[0065] In other embodiments, the second connecting member 40 may also be configured as an aluminum profile with a rectangular cylindrical structure, and is fixed to the first connecting member 30 and the second beam body 20 respectively by fastening structures such as screws.

[0066] In this embodiment, the first plate body 41 and the second plate body 42 are connected by bending, so that it is convenient to realize that the first plate body 41 is stacked on the first connecting member 30, and the second plate body 42 is stacked on the second side wall 21. At the same time, the first plate body 41 and the second plate body 42 are integrally formed into a bending structure, which can further improve the overall strength of the second connecting member 40, improve the connection stability between the second beam body 20 and the first connecting member 30, and can reduce the assembly process and improve the assembly efficiency. In other embodiments, the first plate body 41 and the second plate body 42 can be fixedly connected by other connection methods such as welding, riveting, and screwing.

[0067] In this embodiment, see Figure 6 and Figure 7 , a first plate body 41 of a second connecting member 40 is provided with a plurality of welding holes 43 distributed at intervals, and the beam connection structure 100 also includes a plurality of first welding portions 51, which are respectively provided in the plurality of welding holes 43 and are used for welding and connecting the second connecting member 40 and the first connecting member 30.

[0068] In this embodiment, the first welding portion 51 can be configured as an arc-shaped welding seam.

[0069] In this embodiment, see Figure 6 and Figure 7 There are three welding holes 43 , and the three welding holes 43 are distributed at three vertices of the triangle to improve the connection stability between the first plate body 41 and a third side wall 34 of the first connecting member 30 .

[0070] In this embodiment, see Figure 6 The first plate 41 of the other second connecting member 40 is provided with a protrusion 44 protruding outward along the third side wall 34. The protrusion 44 can play a buffering and energy absorption role when the second connecting member 40 is subjected to external force, thereby ensuring the connection reliability between the second connecting member 40, the first connecting member 30 and the second beam body 20.

[0071] In this embodiment, see Figure 4 The first beam body 10 is installed in the installation hole 31 , wherein two first side walls 11 are respectively stacked on the first side wall 32 and the second side wall 33 , and the other two first side walls 11 are respectively stacked on the two third side walls 34 .

[0072] In this embodiment, the first beam body 10 is welded to the first side wall 32 , the second side wall 33 and the two third side walls 34 .

[0073] Specifically, on the side of the first connecting member 30 away from the second beam body 20 along the third direction Y, the two first side walls 11 spaced apart along the second direction X are connected to the first side wall 32 and the second side wall 33 respectively through the two second welding portions 52, and the two first side walls 11 spaced apart along the first direction Z are connected to the two third side walls 34 respectively through the two second welding portions 52. On the side of the first connecting member 30 close to the second beam body 20 along the third direction Y, the two first side walls 11 spaced apart along the second direction X are connected to the first side wall 32 and the second side wall 33 respectively through the two third welding portions 53, and the two first side walls 11 spaced apart along the first direction Z are connected to the two third side walls 34 respectively through the two third welding portions 53.

[0074] The second welding portion 52 and the third welding portion 53 may be respectively configured as arc-shaped welds.

In this way, the two ends of the first beam body 10 are connected to the two second beam bodies 20 through the same structure, further strengthening the overall strength of the beam connection structure 100.
