[0049] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0050] Such as Figure 1 and Figure 2As shown, in one embodiment, the vehicle frame 100 includes a cross beam 1, longitudinal beams 2, and a connecting member 3; the longitudinal beams 2 are connected to the cross beam 1; the connecting member 3 includes a first connecting arm 31 and a second connecting arm 32; one end of the first connecting arm 31 is connected to the cross beam 1, and the other end of the first connecting arm 31 is connected to the longitudinal beam 2; one end of the second connecting arm 32 is connected to the first connecting arm 31, and the other end of the second connecting arm 32 is connected to the cross beam 1 and / or the longitudinal beam 2.

[0051] In this embodiment, after the cross beam 1 and the longitudinal beam 2 are connected, they are respectively connected to the cross beam 1 and the longitudinal beam 2 again through the connecting member 3, which can enhance the connection strength between the cross beam 1 and the longitudinal beam 2. In addition, the connecting member 3 includes two connecting arms, namely the first connecting arm 31 and the second connecting arm 32. After assembly, the connecting member 3 and at least one of the cross beam 1 and the longitudinal beam 2 can enclose a triangular cavity (or enclose a cavity of other shapes), thereby further improving the connection strength between the cross beam 1 and the longitudinal beam 2.

[0052] In some scenarios, the connecting member 3 can also adopt a strip-like structure. After the vehicle frame 100 is assembled, one end of the strip-like connecting member 3 is connected to the cross beam 1, and the other end of the strip-like connecting member 3 is connected to the longitudinal beam 2. At this time, the strip-like connecting member 3 is equivalent to the first connecting arm 31 in this embodiment.

[0053] Compared with the way of setting the connecting member 3 with a strip-like structure, the setting in this embodiment is equivalent to adding an additional connecting arm (that is, adding an additional second connecting arm 32), and one end of this connecting arm is connected to the cross beam 1 or the longitudinal beam 2, and the other end of this connecting arm is connected to the first connecting arm 31. Compared with the way of setting the connecting member 3 with a strip-like structure, the setting in this embodiment can not only enhance the connection strength between the cross beam 1 and the longitudinal beam 2, but also enhance the strength of the connecting member 3.

[0054] In an application scenario, the cross beam 1 is arranged to be able to connect a trailer hitch 4.

[0055] Such as Figure 3 and Figure 4 As shown, in one embodiment, the first end of the first connecting arm 31 is connected to the cross beam 1, the second end of the first connecting arm 31 is connected to the longitudinal beam 2, and the end of the second connecting arm 32 far from the first connecting arm 31 is connected to the longitudinal beam 2.

[0056] Such as Figure 5 and Figure 6As shown, in one embodiment, in the first direction, the second connecting arm 32 includes a first plate 321 and a second plate 322 connected in sequence; in the first direction, the first plate 321 is stacked on the first connecting arm 31; in the first direction, the second plate 322 is located on the side of the first plate 321 away from the second connecting arm 32; the second plate 322 is configured to be able to connect the crossbeam 1 and / or the longitudinal beam 2. This configuration can facilitate the production and preparation of the connecting member 3, and this configuration can also reduce the weight of the connecting member 3, and can achieve cost reduction while optimizing the connection performance of the crossbeam 1 and the longitudinal beam 2.

[0057] The first direction is the arrangement direction of the first connecting arm 31 and the second connecting arm 32. In addition, the first direction may be a vertical direction, and the second connecting arm 32 may be located above the first connecting arm 31.

[0058] In a feasible implementation, both the first plate 321 and the second plate 322 may be flat plate structures, and the area of the first connecting arm 31 used to connect to the first plate 321 is also a flat plate.

[0059] like Figure 5 and Figure 6 As shown, in one embodiment, the second plate 322 is set at an obtuse angle with the first plate 321. During production, the second connecting arm 32 can be prepared by a bending process, and the angle between the first plate 321 and the second plate 322 is set to an obtuse angle, which can ensure the connection strength between the first plate 321 and the second plate 322.

[0060] After assembly, in the length direction of the longitudinal beam 2, the second plate 322 is located between the first plate 321 and the cross beam 1, and the second plate 322 is inclined upward. In addition, the first plate 321 and the first connecting arm 31 may be welded together.

[0061] Since the first connecting arm 31 connects the cross beam 1 and the longitudinal beam 2 respectively, a portion of the first connecting arm 31 is also located between the first plate 321 and the cross beam 1 in the length direction of the longitudinal beam 2 .

[0062] like Figure 5 and Figure 6 As shown, in one embodiment, in the second direction, the first connecting arm 31 includes a third plate 311 and a fourth plate 312 connected in sequence; in addition, in the first direction, the first plate 321 is stacked on the third plate 311, and the fourth plate 312 is located on the side of the third plate 311 away from the first plate 321. The first direction intersects with the second direction, and preferably, the first direction and the second direction may be perpendicular, and in this case, the second direction may be parallel to the length direction of the longitudinal beam 2.

[0063] like Figure 5 and Figure 6As shown, in one embodiment, in a first direction, the second plate 322 and the third plate 311 are spaced apart and opposite to each other. "In the first direction, the second plate 322 and the third plate 311 are spaced apart and opposite to each other" means that in the first direction, the second plate 322 and the third plate 311 are spaced apart and the second plate 322 and the third plate 311 are opposite to each other.

[0064] Wherein, in the first direction, the second plate 322 and the third plate 311 being opposite to each other may mean that in the orthographic projection on a first plane, the projection of the first plate 321 and the projection of the second plate 322 have an overlapping area, wherein the first plane is perpendicular to the first direction.

[0065] As Figure 5 and Figure 6 As shown, in a second direction, the arrangement direction from the first plate 321 to the second plate 322 is the same as the direction from the third plate 311 to the fourth plate 312. At this time, in the second direction, a part of the third plate 311 and the fourth plate 312 are located between the first plate 321 and the cross beam 1, and the part of the third plate 311 located between the first plate 321 and the cross beam 1 is spaced apart and opposite to the second plate 322.

[0066] In an application scenario, the first plate 321 is located above the third plate 311, the second plate 322 protrudes upward from the first plate 321, and the fourth plate 312 protrudes downward from below the third plate 311. In addition, in the second direction, the second plate 322 is located between the first plate 321 and the cross beam 1, and the fourth plate 312 is located between the third plate 311 and the cross beam 1.

[0067] In an achievable implementation manner, both the third plate 311 and the fourth plate 312 are of flat plate structures.

[0068] After the connector 3 is assembled, in the second direction, the end of the first plate 321 facing away from the second plate 322 and the end of the third plate 311 facing away from the fourth plate 312 may be flush, and moreover, in the length direction of the cross beam 1 (defining this direction as the third direction), the two ends of the first plate 321 are respectively flush with the two ends of the third plate 311. Wherein, both the first direction and the second direction are perpendicular to the third direction. Wherein, when the vehicle frame 100 is applied to a vehicle, the first direction may be the height direction of the vehicle, the second direction may be the length direction of the vehicle, and the third direction may be the width direction of the vehicle.

[0069] As Figure 3 and Figure 6 As shown, in one embodiment, the first plate 321, the second plate 322, and the third plate 311 are all arranged to be able to connect to the longitudinal beam 2, and the fourth plate 312 is arranged to be able to connect to the cross beam 1.

[0070] As Figure 6As shown, in one embodiment, at least one of the first plate 321, the second plate 322, the third plate 311, and the fourth plate 312 is provided with a reinforcing rib 33. When a plate is provided with a reinforcing rib 33, the strength of the plate can be improved.

[0071] In addition, when a plate is provided with a reinforcing rib 33, the reinforcing rib 33 can be formed on the plate by stamping or other means, that is, after the plate is stamped, it can bulge in one direction to form a reinforcing rib; alternatively, when a plate is provided with a reinforcing rib 33, the reinforcing rib 33 can also be a rib welded to the plate.

[0072] As Figure 6 shown, in one embodiment, both the first plate 321 and the second plate 322 are provided with a reinforcing rib 33. Among them, at least a part of the reinforcing rib 33 provided on the first plate 321 is the first reinforcing rib 323, and at least a part of the reinforcing rib 33 provided on the second plate 322 is the second reinforcing rib 324.

[0073] Among them, the first reinforcing rib 323 is provided on the surface of the first plate 321 facing away from the first connecting arm 31, and the second reinforcing rib 324 is provided on the surface of the second plate 322 facing away from the first connecting arm 31; the first reinforcing rib 323 and the second reinforcing rib 324 are of an integral structure, which can further improve the strength of the second connecting arm 32. Among them, in addition to the first reinforcing rib 323, other reinforcing ribs 33 can also be provided on the first plate 321; in addition to the second reinforcing rib 324, other reinforcing ribs 33 can also be provided on the second plate 322.

[0074] In one embodiment, at least a part of the edge of the first plate 321 is a flanging structure, that is, the edge part of the first plate 321 is bent toward the side close to the first connecting arm 31, or the edge part of the first plate 321 is bent toward the side away from the first connecting arm 31. This can improve the strength of the first plate 321 and also improve the strength of the overlapping area between the first plate 321 and the first connecting arm 31.

[0075] The overlapping area between the first plate 321 and the first connecting arm 31 may refer to the area that can overlap in the orthographic projection of the first plate 321 and the first connecting arm 31 on the first plane.

[0076] In addition, at least a part of the edge of the second plate 322 is a flanging structure, that is, the edge part of the second plate 322 is bent toward the side close to the first connecting arm 31, or the edge part of the second plate 322 is bent toward the side away from the first connecting arm 31, which can improve the strength of the second plate 322.

[0077] As Figure 3As shown, in one embodiment, the longitudinal beam 2 includes a longitudinal beam body 21 and a first longitudinal beam reinforcement plate 22; the first longitudinal beam reinforcement plate 22 is connected to one end of the longitudinal beam body 21 and connected to the cross beam 1, and the first longitudinal beam reinforcement plate 22 is located between the longitudinal beam body 21 and the cross beam 1; the first longitudinal beam reinforcement plate 22 is provided with an avoidance hole 221, and the avoidance hole 221 penetrates the first longitudinal beam reinforcement plate 22 along the length direction of the longitudinal beam body 21; the first connecting arm 31 is penetrated through the avoidance hole 221 and connected to the longitudinal beam body 21; the second connecting arm 32 is located on the side of the first longitudinal beam reinforcement plate 22 away from the cross beam 1, and connected to the first longitudinal beam reinforcement plate 22. Such a configuration can improve the connection strength between the connecting member 3 and the longitudinal beam 2, and the connecting member 3 connects the longitudinal beam body 21 and the first longitudinal beam reinforcement plate 22 respectively, which can also improve the connection strength between the longitudinal beam body 21 and the first longitudinal beam reinforcement plate 22.

[0078] The length direction of the longitudinal beam body 21 is the length direction of the longitudinal beam 2. The first longitudinal beam reinforcement plate 22 protrudes from the outer side of the longitudinal beam body 21, and the part of the first longitudinal beam reinforcement plate 22 protruding from the outer side of the longitudinal beam body 21 can be connected to the cross beam 1. In addition, the first longitudinal beam reinforcement plate 22 can be a flat plate structure.

[0079] The first connecting arm 31 passes through the first longitudinal beam reinforcement plate 22 from the avoidance hole 221. At this time, the first end of the first connecting arm 31 is located between the longitudinal beam reinforcement plate 22 and the cross beam 1, and the second end of the first connecting arm 31 is located on the side of the first longitudinal beam reinforcement plate 22 away from the cross beam 1; the second end of the first connecting arm 31 is connected to the longitudinal beam body 21.

[0080] In addition, when the first connecting arm 31 is connected to the longitudinal beam body 21 , the third plate 311 is connected to the longitudinal beam body 21 .

[0081] The second plate 322 is located on a side of the first longitudinal beam reinforcement plate 22 away from the cross beam, and the second plate 322 is connected to the first longitudinal beam reinforcement plate 22. The second connecting arm 32 is also connected to the longitudinal beam body 21, and specifically, the first plate 321 is connected to the longitudinal beam body 21.

[0082] like Figure 3 As shown, in one embodiment, the longitudinal beam body 21 is provided with a receiving groove 211, and the receiving groove 211 penetrates the longitudinal beam body 21 along the length direction of the longitudinal beam body 21; the receiving groove 211 is opposite to the avoidance hole 221; and the first connecting arm 31 is located in the receiving groove 211. In this way, the weight of the longitudinal beam 2 can be reduced, which is conducive to the lightweight design of the frame 100. Moreover, by arranging the first connecting arm 31 in the receiving groove 211, the interference of the first connecting arm 31 with the arrangement of other components can also be reduced.

[0083] like Figure 9As shown, in one embodiment, the longitudinal beam 2 further includes a second longitudinal beam reinforcement plate 23. The second longitudinal beam reinforcement plate 23 is disposed in the receiving groove 211 and is connected to the longitudinal beam body 21. The first connecting arm 31 is located in the receiving groove 211 and is connected to the second longitudinal beam reinforcement plate 23. At this time, the first connecting arm 31 is connected to the longitudinal beam body 21 through the second longitudinal beam reinforcement plate 23.

[0084] As Figure 10 shown, in one embodiment, the second longitudinal beam reinforcement plate 23 includes a first connecting plate 231, a second connecting plate 232, and a third connecting plate 233 that are connected in sequence. Both the first connecting plate 231 and the third connecting plate 233 are located on one side of the second connecting plate 232 facing away from the bottom wall of the receiving groove 211, and the first connecting plate 231 and the third connecting plate 233 are respectively connected to the two side walls of the receiving groove. The second connecting plate 232 is connected to the bottom wall of the receiving groove. The first connecting arm 31 is located between the first connecting plate 231 and the third connecting plate 233 and is connected to at least one of the first connecting plate 231 and the third connecting plate 233.

[0085] Among them, the first connecting plate 231, the second connecting plate 232, and the third connecting plate 233 are connected to form a U-shaped structure, and the first connecting arm 31 is located on one side of the second connecting plate 232 facing away from the bottom wall of the receiving groove 211.

[0086] In addition, preferably, both the first connecting plate 231 and the third connecting plate 233 are connected to the first connecting arm 31.

[0087] As Figure 3 and Figure 6 shown, in one embodiment, the first connecting arm 31 is connected to the second longitudinal beam reinforcement plate 23 through a first weld seam 10, that is, the first connecting arm 31 is welded to the second longitudinal beam reinforcement plate 23. Specifically, the first connecting arm 31 is welded to the first plate 231, and the first connecting arm 31 is also welded to the third plate 233; and / or, the first connecting arm 31 is connected to the cross beam 1 through a second weld seam 20, that is, the first connecting arm 31 is welded to the cross beam 1; and / or, the second connecting arm 32 is connected to the first longitudinal beam reinforcement plate 22 through a third weld seam 30, that is, the second connecting arm 32 is welded to the first longitudinal beam reinforcement plate 22.

[0088] Compared with the setting method of using bolts to connect the connecting member 3 and the cross beam 1, or using bolts to connect the connecting member 3 and the longitudinal beam 2, the setting of this embodiment can reduce the number of bolts and nuts, thereby reducing costs and weight. Moreover, this can also eliminate the problem of bolt loosening caused by repeated impact loads.

[0089] When the first connecting arm 31 is welded to the main beam body 21, the first plate 321 and the main beam body 21 can also be welded together, that is, the first plate 321 can also be connected to the main beam body 21 through the first weld seam 10, which can improve the connection firmness between the first connecting arm 31 and the main beam body 21. When the first connecting arm 31 is welded to the cross beam 1, in fact, the fourth plate 312 is welded to the cross beam 1. When the second connecting arm 32 is welded to the first main beam reinforcing plate 22, in fact, one end of the second plate 322 facing away from the first plate 321 is welded to the first main beam reinforcing plate 22.

[0090] As Figure 1 and Figure 6 shown, in an embodiment, the cross beam 1 includes a cross beam body 11 and a cross beam mounting plate 12. The cross beam mounting plate 12 is connected to one end of the cross beam 1, and the connecting member 3 is connected to the cross beam mounting plate 12. The length direction of the cross beam body 11 is the length direction of the cross beam 1.

[0091] As Figure 1 and Figure 6 shown, in an embodiment, the cross beam mounting plate 12 includes a first mounting plate 121, a second mounting plate 122, and a third mounting plate 123; the first mounting plate 121 is connected to the cross beam body 11, the second mounting plate 122 is connected to the first mounting plate 121, and the connection between the first mounting plate 121 and the second mounting plate 122 forms a bent structure; the second mounting plate 122 is respectively connected to the longitudinal beam 2 and the connecting member 3, and the longitudinal beam 2 and the connecting member 3 are on the same side of the second mounting plate 122; the third mounting plate 123 is respectively connected to the first mounting plate 121 and the second mounting plate 122, and the third mounting plate 123 is on the side of the second mounting plate 122 facing away from the longitudinal beam 2.

In addition, the spacer plate 6 is further provided with corresponding avoidance structures to avoid interference with the connection between the connecting member 3 and the second mounting plate 122.

[0100] When both the rear apron 5 and the spacer plate 6 are disposed between the first longitudinal beam reinforcing plate 22 and the second mounting plate 122, the rear apron 5 can be disposed between the spacer plate 6 and the first longitudinal beam reinforcing plate 22.
