[0045] As described in the background art, the frame of a light truck has many parts, which makes the frame assembly complicated and heavy. The inventors have found that the reason for this problem is that the connecting plate and the longitudinal beam are connected by bolts and nuts, which makes the frame have many parts, which makes the frame assembly complicated and heavy.

[0046] In order to solve the above problems, the embodiments of the utility model provide an aluminum alloy frame assembly and a vehicle, in which a connecting plate is integrated on a longitudinal beam body, so that the longitudinal beam body and the connecting plate do not need to be fixed by fixing parts, and the longitudinal beam body and the connecting plate do not need to be assembled, thereby reducing the number of parts of the aluminum alloy frame assembly, thereby simplifying the assembly of the aluminum alloy frame assembly, reducing the weight of the aluminum alloy frame assembly, and reducing the production cost of the aluminum alloy frame assembly.

[0047] The aluminum alloy frame assembly and the vehicle provided by the utility model embodiment are described in detail below in conjunction with specific embodiments.

[0048] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an aluminum alloy frame assembly, including two longitudinal beams 10 and multiple cross beams 20; the longitudinal beam 10 includes an integrally formed longitudinal beam body 11 and a connecting plate 12; the multiple cross beams 20 are arranged between the two longitudinal beams 10, and each cross beam 20 is fixed to the connecting plate 12 of the longitudinal beam 10 by a fixing member 30.

[0049] Among them, the material of the longitudinal beam 10 and the cross beam 20 is aluminum alloy, which can reduce the weight of the aluminum alloy frame assembly and make the aluminum alloy frame assembly lightweight.

[0050] The longitudinal beam body 11 and the connecting plate 12 of the longitudinal beam 10 are integrally formed by extrusion of aluminum alloy.

[0051] like Figure 3 As shown, the length direction of the longitudinal beam 10 is the X-axis direction, the width direction of the longitudinal beam 10 is the Y-axis direction, and the height direction of the longitudinal beam 10 is the Z-axis direction. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0052] The two longitudinal beams 10 are spaced apart along the Y-axis direction to form an installation space.

[0053] The cross beam 20 is formed by extrusion of aluminum alloy and can be an I-beam, a Z-beam, an M-beam or a square beam.

[0054] A plurality of cross beams 20 are located in the installation space. The plurality of cross beams 20 are spaced apart along the length direction of the longitudinal beams 10 . Each cross beam 20 is fixed to the connecting plates 12 of two longitudinal beams 10 by using fixing members 30 .

[0055] The number of cross beams 20 can be set according to the load-bearing capacity of the aluminum alloy frame assembly.

[0056] The fixing member 30 may be a bolt and a nut, or a rivet, or other components capable of fixing the cross beam 20 and the connecting plate 12 .

[0057] The aluminum alloy frame assembly provided by the embodiment of the utility model integrally forms the longitudinal beam body 11 and the connecting plate 12, so that the longitudinal beam body 11 and the connecting plate 12 are integrated, so that the longitudinal beam body 11 and the connecting plate 12 do not need to be fixed by fixing parts, and the longitudinal beam body 11 and the connecting plate 12 do not need to be assembled, thereby reducing the number of parts of the aluminum alloy frame assembly, thereby simplifying the assembly of the aluminum alloy frame assembly, reducing the weight of the aluminum alloy frame assembly, and reducing the production cost of the aluminum alloy frame assembly.

[0058] In a possible implementation, Figure 3 and Figure 4 As shown, the longitudinal beam body 11 includes a first connecting section 111 and two second connecting sections 112. The two second connecting sections 112 are respectively intersected and connected with the two ends of the first connecting section 111. The two second connecting sections 112 are respectively connected to a connecting plate 12. That is to say, the longitudinal beam body 11 is connected to the two connecting plates 12, and the cross beam 20 is connected between the two connecting plates 12.

[0059] The first connecting section 111 is parallel to a plane defined by the X-axis and the Z-axis, the length direction of the first connecting section 111 is the X-axis direction, and the height direction of the first connecting section 111 is the Z-axis direction.

[0060] The two second connecting segments 112 are respectively intersected and connected with both ends of the first connecting segment 111 in the Z-axis direction. Exemplarily, the second connecting segment 112 is parallel to the plane defined by the X-axis and the Y-axis, the length direction of the second connecting segment 112 is the X-axis direction, and the width direction of the second connecting segment 112 is the Z-axis direction. It can be understood that the second connecting segment 112 is vertically connected to the first connecting segment 111.

[0061] One end of the second connecting section 112 away from the first connecting section 111 is connected to the connecting plate 12 .

[0062] The connecting plate 12 may be directly connected to the second connecting section 112 or indirectly connected to the second connecting section 112 .

[0063] The connecting plate 12 of the longitudinal beam 10 and the cross beam 20 have corresponding threaded holes. In a possible implementation, the fixing member 30 includes a bolt 31 and a nut 32. When the longitudinal beam 10 and the cross beam 20 are assembled, the cross beam 20 is placed between the two connecting plates 12 of the longitudinal beam 10, and the threaded holes on the connecting plate 12 are aligned with the threaded holes on the cross beam 20. After that, the bolt 31 passes through the threaded holes of the connecting plate 12 and the threaded holes of the cross beam 20 and is connected with the nut 32, so that the longitudinal beam 10 and the cross beam 20 are relatively fixed.

[0064] Figure 4 The cross section of the longitudinal beam 10 is parallel to the plane defined by the Y-axis and the Z-axis.

[0065] In a possible implementation, Figure 4 As shown, the two second connecting sections 112 are both connected to the back-wrapped section 113, that is, the longitudinal beam body 11 includes two back-wrapped sections 113. The back-wrapped section 113 extends toward the cross beam 20, and the back-wrapped section 113 is connected between the connecting plate 12 and the second connecting section 112. In this way, the connecting plate 12 can be indirectly connected to the second connecting section 112 through the back-wrapped section 113, thereby avoiding the connecting plate 12 from being connected to the second connecting section 112 after the thickness is increased, thereby reducing the thickness of the connecting plate 12 and achieving lightweight aluminum alloy frame assembly.

[0066] The return packet segment 113 is connected to an end of the second connection segment 112 away from the first connection segment 111. Exemplarily, the return packet segment 113 is parallel to the plane defined by the X-axis and the Z-axis, the length direction of the return packet segment 113 is the X-axis direction, and the height direction of the return packet segment 113 is the Z-axis direction. It can be understood that the return packet segment 113 is perpendicular to the second connection segment 112 and parallel to the first connection segment 111.

[0067] Furthermore, the two connecting plates 12 of the longitudinal beam 10 are parallel and perpendicular to the first connecting section 111, and one end of each connecting plate 12 away from the back-wrapped section 113 is exposed outside the longitudinal beam body 11. This arrangement facilitates the assembly of the cross beam 20 and the connecting plates 12.

[0068] Among them, the connecting plate 12 is parallel to the plane defined by the X-axis and the Y-axis, the length direction of the connecting plate 12 is the X-axis direction, and the width direction of the connecting plate 12 is the Y-axis direction. It can be understood that the connecting plate 12 is vertically connected to the return package section 113, the connecting plate 12 is parallel to the second connecting section 112, and the connecting plate 12 is vertical to the first connecting section 111.

[0069] A threaded hole is provided on one end of the connecting plate 12 away from the back-packing section 113 , and the threaded hole is exposed outside the longitudinal beam body 11 . This arrangement facilitates the bolt 31 to pass through the threaded hole of the connecting plate 12 .

[0070] In a possible implementation, Figure 3 and Figure 4 As shown, a reinforcing rib 13 is connected between the connecting plate 12 and the first connecting section 111, that is, the longitudinal beam 10 includes the reinforcing rib 13, and the reinforcing rib 13 is integrally formed with the longitudinal beam body 11. In this way, when the aluminum alloy frame assembly bears load, the first connecting section 111 and the connecting plate 12 are connected by the reinforcing rib 13, which can avoid stress concentration on the connecting plate 12 of the longitudinal beam 10, thereby improving the service life of the longitudinal beam 10 and improving the strength of the longitudinal beam 10.

[0071] The longitudinal beam body 11, the connecting plate 12 and the reinforcing ribs 13 are integrally formed by extrusion of aluminum alloy.

[0072] The reinforcing rib 13 extends along the X-axis direction.

[0073] In a possible implementation, Figure 3 and Figure 4 As shown, a plurality of reinforcing plates 14 are connected to the first connecting section 111, that is, the longitudinal beam 10 includes a plurality of reinforcing plates 14, and the plurality of reinforcing plates 14 are arranged at intervals along the height direction of the longitudinal beam 10, and each reinforcing plate 14 is integrally formed with the longitudinal beam body 11. In this arrangement, the reinforcing plates 14 and the longitudinal beam body 11 do not need to be fixed, which can reduce the number of parts of the aluminum alloy frame assembly.

[0074] Among them, the longitudinal beam body 11, the connecting plate 12, the reinforcing rib 13 and the reinforcing plate 14 are formed in one piece by extruding an aluminum alloy. By extruding the aluminum alloy, the thickness of the longitudinal beam 10 formed is uneven, and the reinforcing plate 14 and the first connecting section 111 can be formed. It can be understood that in the area where the first connecting section 111 of the longitudinal beam 10 is located, the thicker part is composed of the reinforcing plate 14 and a part of the first connecting section 111, and the thinner part is composed of only another part of the first connecting section 111. For the area where the first connecting section 111 of the longitudinal beam 10 is located, the thicker part can be used to install the stressed bracket or bolt on the vehicle, that is, the stressed bracket or bolt on the vehicle can be installed on the reinforcing plate 14 and the first connecting section 111.

[0075] The reinforcing plate 14 is disposed on the inner side of the longitudinal beam 10 , that is, the reinforcing plate 14 is located on one side of the first connecting section 111 in the +Y axis direction.

[0076] The reinforcing rib 13 is connected between the connecting plate 12 and the reinforcing plate 14 .

[0077] In a possible implementation, the chamfer at the inner side of the connection between the first connection section 111 and the second connection section 112 is greater than the chamfer at the outer side of the connection between the first connection section 111 and the second connection section 112. This arrangement can avoid stress concentration at the connection between the first connection section 111 and the second connection section 112, thereby extending the service life of the longitudinal beam 10.

[0078] Among them, Figure 4 As shown, the inner chamfer of the connection between the first connection segment 111 and the second connection segment 112 is a first chamfer R1 ; the outer chamfer of the connection between the first connection segment 111 and the second connection segment 112 is a second chamfer R2 .

[0079] An embodiment of the utility model provides a vehicle, comprising an aluminum alloy frame assembly.

[0080] Among them, the driving aluminum alloy frame assembly in this embodiment has the same structure as the aluminum alloy frame assembly provided in any of the above embodiments, and can bring the same or similar technical effects, which will not be described one by one here, and the details can be referred to the description of the above embodiments.

[0081] It should be noted that the vehicle in this embodiment may refer to a light truck, a heavy truck, etc.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
