In addition, the present application also provides a vehicle including the above-mentioned vehicle frame.

[0004] In order to achieve the above objectives, this application provides the following technical solutions:

[0005] A vehicle frame comprising:

[0006] Two longitudinal beams set at intervals;

[0007] A flat crossbeam is used, the flat surface of which is perpendicular to the supporting direction of the frame, and the crossbeam is arranged on the top of the longitudinal beam, with both ends of the crossbeam respectively connected to the outer side surfaces of the two longitudinal beams.

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The vehicle frame in the embodiment of the present application is a load-bearing component of the vehicle, and is particularly suitable for vehicles that require more power batteries to be arranged inside the vehicle frame.

[0032] like Figure 1-Figure 4 As shown, the frame provided by the embodiment of the present application includes a crossbeam 2 and two longitudinal beams 1, wherein the two longitudinal beams 1 are arranged at intervals, the crossbeam 2 adopts a flat design, and the flat surface of the crossbeam 2 is perpendicular to the support direction of the frame, and the support direction of the frame is parallel to and opposite to the direction of gravity. The crossbeam 2 is arranged on the top of the longitudinal beam 1, and the two ends of the crossbeam 2 are respectively connected to the outer side surfaces of the two longitudinal beams 1.

[0033] It should be noted that the cross beam 2 is arranged on the top of the longitudinal beam 1 in the above text, which means that the cross beam 2 is arranged close to the supporting side of the longitudinal beam 1 (the supporting side is the side of the longitudinal beam 1 away from the ground) in the supporting direction of the frame. Figure 1 As shown, in a specific embodiment, the flat surface on the top of the beam 2 is flush with the top surface of the beam 2 .

[0034] It should also be noted that, in the embodiment of the present application, the surfaces facing each other between the two longitudinal beams 1 are the inner surfaces of the longitudinal beams 1 , and the surfaces facing away from each other between the two longitudinal beams 1 are the outer surfaces of the longitudinal beams 1 .

[0035] In the aforementioned vehicle frame, since crossbeam 2 is flat and its flat surface is perpendicular to the frame's support direction, when assembled to longitudinal beam 1, crossbeam 2 requires less space in the support direction. Furthermore, crossbeam 2 is positioned atop longitudinal beam 1, with its ends connected to the outer sides of the two longitudinal beams 1. This allows the space beneath crossbeam 2 on the inner sides of the longitudinal beams 1 (i.e., between the two longitudinal beams 1) to be reserved for the power battery, thereby maximally meeting the power battery layout requirements. Furthermore, the flat design of crossbeam 2 also reduces its weight, contributing to the vehicle's lightweight design.

[0036] More preferably, the cross beam 2 is vertically arranged on the top of the longitudinal beam 1, that is, in the supporting direction of the frame, the cross beam 2 is arranged close to the supporting side of the longitudinal beam 1 (the supporting side is the side of the longitudinal beam 1 away from the ground), and the length direction of the cross beam 2 (the length direction of the cross beam 2 can be referred to Figure 1 The Y direction in the figure, the same below) is perpendicular to the length direction of the longitudinal beam 1 (the length direction of the longitudinal beam 1 can be referred to Figure 1 This arrangement minimizes the space occupied by the cross beam 2 in the supporting direction and the longitudinal beam 1 in the length direction.

[0037] In some optional embodiments, such as Figure 1 and Figure 2 As shown, both ends of the crossbeam 2 are connected to the longitudinal beam 1 via a connector 3. The connector 3 includes a first connector 301 and a second connector 302. The first connector 301 abuts the outer side of the longitudinal beam 1 and is fixed to the longitudinal beam 1 by welding or threading. The second connector 302 is integrated with the first connector 301 or fixedly connected to the first connector 301. In other words, the second connector 302 and the first connector 301 are integrally formed or the second connector is an independent structure and fixedly connected to the first connector 301. When the second connector is an independent structure and fixedly connected to the first connector 301, its connection method can be welding or threading, which is not specifically limited in this application. In addition, the second connector 302 is connected to the crossbeam 2, and the crossbeam 2 and the longitudinal beam 1 are connected by the connector 3. Under this setting method, during the vehicle assembly process, the connecting member 3 can be pre-set on the longitudinal beam 1, and then the accessories (such as the power battery) located between the two longitudinal beams 1 can be assembled, and finally the connecting member 3 is used to connect the cross beam 2 and the longitudinal beam 1; under this assembly sequence, the cross beam 2 can be prevented from interfering with the installation of accessories, thereby ensuring assembly efficiency.

[0038] In other optional embodiments, the ends of crossbeam 2 are directly fixed to longitudinal beam 1, that is, the ends of crossbeam 2 have connecting structures that can be directly connected to longitudinal beam 1. In one exemplary embodiment, crossbeam 2 and longitudinal beam 1 are detachably connected via bolts. Specifically, the longitudinal beam 1 has a first bolt hole at the location where crossbeam 2 is to be connected, and the end of crossbeam 2 is bent and provided with a second bolt hole. During connection, after aligning the first bolt hole with the second bolt hole, a bolt is inserted through the first and second bolt holes, and the nut is tightened to connect crossbeam 2 to longitudinal beam 1. This arrangement helps simplify the connection structure between crossbeam 2 and longitudinal beam 1 and further improves the overall strength of the vehicle frame.

[0039] Furthermore, on the basis of the cross beam 2 being connected to the longitudinal beam 1 via the connector 3, multiple cross beams 2 are provided along the length direction of the longitudinal beam 1, and the ends of all cross beams 2 connected to the same longitudinal beam 1 are connected to the longitudinal beam 1 via the same connector 3. In this arrangement, the multiple cross beams 2 are connected as a whole via the connector 3, providing better structural stability and overall rigidity. At the same time, the provision of multiple cross beams 2 can also effectively reduce stress concentration, thereby improving the durability and reliability of the vehicle frame.

[0040] It should be noted that the number of beams 2 is not specifically limited in this application, and can be adaptively designed as needed during the specific implementation process. Figure 1-Figure 3 As shown, the number of cross beams 2 can be two, and the two cross beams 2 are arranged side by side, and the ends of the two cross beams 2 connected to the same longitudinal beam 1 are connected to the longitudinal beam 1 through the same connecting member 3. In addition, in some other embodiments, the number of cross beams 2 can also be three or four.

[0041] In some embodiments, the end of the cross beam 2 abuts against the inner side of the longitudinal beam 1 (the definition of the inner side is detailed above) to cooperate with the first connecting portion 301 to clamp the longitudinal beam 1. Specifically, Figure 3 As shown, the end of the crossbeam 2 is spaced apart from the first connecting portion 301 of the connecting member 3, and the distance between the end of the crossbeam 2 and the first connecting portion 301 is equal to the width of the longitudinal beam 1. In this way, a snap-in groove can be formed between the end of the crossbeam 2, the first connecting portion 301 and the second connecting portion 302, and during the assembly process, the snap-in groove can be snapped onto the longitudinal beam 1. In this way, the stability of the connection between the crossbeam 2 structure and the longitudinal beam 1 can be further improved.

[0042] On the basis of the crossbeam 2 cooperating with the first connecting portion 301 to clamp the longitudinal beam 1, it is further preferred that a guide structure can be provided at the end of the crossbeam 2. For example, a guide slope can be provided on the side of the end of the crossbeam 2 facing the ground. This is more conducive to reducing the difficulty of assembling the crossbeam 2 and thereby improving the assembly efficiency.

[0043] Furthermore, an avoidance structure 10 is provided at the center of the first connecting portion 301 in the longitudinal direction of the longitudinal beam 1. The avoidance structure 10 is used to avoid the bolt holes for connecting accessories on the longitudinal beam 1. It is understandable that in some vehicles, in order to fully utilize the chassis space of the vehicle, it is necessary to connect some accessories using a bracket-like structure on the outside of the longitudinal beam 1. Based on this, during the assembly process, the avoidance structure 10 in this embodiment can ensure that after the first connecting portion 301 is fixed to the longitudinal beam 1, it will not block the bolt holes on the longitudinal beam 1, thereby ensuring the installation of accessories that need to be fixed using bolts or other connecting structures. In other words, this embodiment can effectively avoid interference between accessories installed on the longitudinal beam 1 and the connecting member 3 through the above-mentioned avoidance structure 10, which is conducive to improving the rationality of the setting position of the first crossbeam 2, and thus improving the deformation resistance and force uniformity of the frame.

[0044] It should be noted that the avoidance structure 10 can be a notch provided in the first connection portion 301, or can be a through hole provided in the first connection portion 301. Figure 1 In the fuel tank 5 and the frame 7, etc.; in a specific implementation, the fuel tank 5 and the frame 7 are fixed to the outer side of the longitudinal beam 1 by the fuel tank connecting plate 4 and the frame connecting plate 6 respectively.

[0045] Furthermore, in some embodiments, the dimension of the avoidance structure 10 does not exceed 200 mm along the length of the longitudinal beam 1. This arrangement satisfies both the lightweight requirements of the structure and the structural strength requirements of the connector 3. Furthermore, with regard to the placement of the avoidance structure 10, it is preferred that the first connecting portion 301 be centered along the length of the longitudinal beam 1. This further helps ensure the strength of the connection structure on both sides of the avoidance structure 10. Of course, the above is only a preferred placement of the avoidance structure 10, and it can be adjusted as needed during implementation.

[0046] like Figure 4 As shown, in some embodiments, the first connection part 301 and the second connection part 302 are both plate-shaped sheet metal parts, and there is an angle between the two. The size of the angle can be adaptively adjusted as needed during the specific implementation process. Preferably, the angle between the first connection part 301 and the second connection part 302 is 90°, that is, the first connection part 301 and the second connection part 302 are perpendicular to each other, the first connection part 301 is in contact with the outer side surface of the longitudinal beam 1, and the second connection part 302 is overlapped on the top surface of the longitudinal beam 1. In this way, a limit is formed between the first connection part 301 and the longitudinal beam 1 and between the second connection part 302 and the longitudinal beam 1, which is more conducive to improving the stability of the connection between the crossbeam 2 and the longitudinal beam 1.

[0047] In other embodiments, the first connection portion 301 and the second connection portion 302 are integrally formed and are a casting or a removed-material-machined part (ie, a part formed by removing material).

[0048] like Figure 2 and Figure 3 As shown, the crossbeam 2 is provided with a crossbeam mounting hole 8 extending along the length direction of the longitudinal beam 1. The crossbeam mounting hole 8 is used to fix various accessories located on the inner side of the longitudinal beam 1.

[0049] In addition, the frame in the embodiment of the present application further includes a reinforcing plate 9, which is used to improve the connection strength. Specifically, the reinforcing plate 9 is located on the inner side of the longitudinal beam 1 and is close to the inner side of the longitudinal beam 1. Figure 2 and Figure 3 As shown, the reinforcing plate 9 is provided with a plurality of connection holes, and at least some of the connection holes of the reinforcing plate 9 are arranged to be aligned with the plurality of connection holes of the first connection portion 301 and are connected via threaded connectors 3 that pass through the longitudinal beam 1. This arrangement allows the different threaded connectors 3 to form a single unit under the action of the reinforcing plate 9, thereby facilitating improved connection strength.

[0050] In addition, an embodiment of the present application also provides a vehicle, which includes the above-mentioned frame.
