[0030] The present invention will be described based on embodiments. Those of ordinary skill in the art should understand that the attached drawings provided here are all for illustrative purposes, and the attached drawings are not necessarily drawn to scale.

[0031] Unless the context clearly requires otherwise, the words such as "include", "comprise" and similar words in the whole specification and claims should be interpreted as the meaning of including rather than exclusive or exhaustive meaning; that is, it is the meaning of "including but not limited to".

[0032] Refer to Figures 1-5 As shown, the frame of the vehicle of the present invention increases the structural strength of the frame of the rear section part of the vehicle body.

[0033] The frame includes a front section part 6 of the vehicle body, a body section part 5 of the vehicle body and a rear section part 4 of the vehicle body. As Figure 1 shown, the front axle of the vehicle is located in the front section part 6 of the frame, and the rear axle of the vehicle is located in the rear section part 4 of the frame.

[0034] The rear section part 4 includes a cross beam 41. As Figure 3 and Figure 4 shown, the cross beam 41 extends along the vehicle width direction of the frame, the cross beam 41 penetrates the entire vehicle width of the frame, the cross beam 41 is an integral structure, and the integral structure cross beam 41 has higher structural strength than the cross beam 41 formed by multi-section welding in the prior art.

[0035] The distance between the cross beam 41 and the lowest end of the vehicle frame is 2424 mm - 2430 mm. Lifting the cross beam 41 can avoid structural components such as the drive shaft, so as to prevent interference between the cross beam 41 and the drive shaft caused by vehicle bouncing due to uneven road surfaces during vehicle driving, thereby avoiding vehicle damage. Moreover, after lifting the cross beam 41, it is set as a complete cross beam, which can improve the overall strength of the vehicle.

[0036] The rear end section 4 further includes a rear axle mounting assembly 42, as Figure 3 and Figure 4 shown. The rear axle of the vehicle is mounted on the rear axle mounting assembly 42. The rear axle of the vehicle is located below the rear axle mounting assembly 42. The rear axle mounting assembly 42 forms a part of the rear end section 4. The cross beam 41 is arranged between the rear axle mounting assembly 42 and the rear of the vehicle.

[0037] The rear axle mounting assembly 42 includes a longitudinal beam 421. The longitudinal beam 421 extends along the length direction of the vehicle frame. One end of the longitudinal beam 421 is connected to the cross beam 41.

[0038] The rear end section 4 further includes a transverse skeleton 45 disposed close to the body section 5. The transverse skeleton 45 is arranged in parallel with the cross beam 41. The other end of the longitudinal beam 421 is connected to the transverse skeleton 45.

[0039] The rear end section 4 further includes a vertical skeleton 46. The vertical skeleton 46 extends along the height direction of the vehicle frame. The upper end of the vertical skeleton 46 is simultaneously connected to the transverse skeleton 45 and the longitudinal beam 421. The rear end section 4 further includes an arc-shaped skeleton 43 and a rear thrust rod seat assembly 44, as Figure 4 shown. The rear thrust rod seat assembly 44 is arranged at the lower part of the connection position between the rear end section 4 and the body section 5. One end of the arc-shaped skeleton 43 is arranged on the rear end section 4 and above the rear thrust rod seat assembly 44. The other end of the arc-shaped skeleton 43 extends obliquely upward to the longitudinal beam 421 of the rear axle mounting assembly 42. The lower end of the vertical skeleton 46 is connected to the arc-shaped skeleton 43. The arc-shaped skeleton 43 can increase the structural strength at the rear axle mounting assembly 42 of the rear end section 4.

[0040] The rear thrust rod seat assembly 44 includes a reinforcement plate 441. The two sides of the reinforcement plate 441 are bent in opposite directions to form a first folded edge 4411, a second folded edge 4412 and an intermediate part 4413 disposed therebetween. The first folded edge 4411 and the intermediate part 4413 cover the welding position between the vehicle body section 5 and the vehicle tail section 4 to increase the connection strength between the vehicle body section 5 and the vehicle tail section 4. One end of the arc-shaped frame 43 is disposed above the second folded edge 4412 and is simultaneously connected to the second folded edge 4412 and a partial structure of the vehicle tail section 4 near the vehicle body section 5. The second folded edge 4412 can increase the connection strength between the arc-shaped frame 43 and the vehicle tail section 4. In the prior art, a diagonal brace is provided between the rear thrust rod seat assembly at the vehicle tail section and the rear axle mounting assembly 42. The diagonal brace is a straight rod, or a combined member formed by at least two straight rods with side walls connected. In the present invention, the use of the complete arc-shaped frame 43 can reduce the amount of welding, and under the same force guiding effect, the strength of the vehicle frame itself is improved.

[0041] The arc-shaped frame 43 protrudes toward the rear axle mounting assembly 42, and one end of the arc-shaped frame 43 is connected to the circumferential mounting assembly 42 to guide the force to the main frame.

[0042] The vehicle tail section 4 further includes a rear suspension airbag connection structure, and the airbag of the vehicle rear suspension part is mounted on the rear suspension airbag connection structure.

[0043] The connection structure includes a connecting member 1 and an airbag mounting plate 2. As Figure 2 shown, the connecting member 1 includes a connecting plate 11. One side of the upper part of the connecting plate 11 is connected to the vehicle tail section 4 of the vehicle frame, and the lower end of the connecting plate 11 is connected to the airbag mounting plate 2. The airbag is mounted on the airbag mounting plate 2. Mounting holes 21 are provided on the airbag mounting plate 2, and the airbag is mounted on the airbag mounting plate 2 through the mounting holes 21. The structure of the connection structure is simple, and the connection structure and the vehicle tail section 4 of the vehicle frame can be connected by means of, for example, welding, and the connection strength is reliable.

[0044] As Figure 1 shown, in the width direction of the vehicle frame, the size of the upper part of the connecting plate 11 is smaller than the size of the lower part of the connecting plate 11 to achieve the purposes of weight reduction, aesthetics and increasing the weld seam. Among them, increasing the weld seam can improve the strength.

[0045] Four airbags are arranged in the rear section 4 of the vehicle, and each airbag is installed through two of the rear suspension airbag connection structures. There are 8 of the rear suspension airbag connection structures, and the connecting plates 11 in two of the rear suspension airbag connection structures are connected to the crossbeam 41. When the airbag works, the reaction force can be better guided to the vehicle frame through the crossbeam 41, and the force on the vehicle frame is more evenly distributed.

[0046] The rear suspension airbag connection structure includes a mounting member 3. The mounting member 3 is connected to the rear part 4 of the vehicle frame. One side of the upper part of the connecting plate 11 is connected to one side wall of the mounting member 3. The two connecting plates 11 connected to the crossbeam 41 are connected to the crossbeam 41 through two mounting members 3 to better transmit the damping force and improve the connection strength of the vehicle frame. Preferably, one side of the upper part of the connecting plate 11 is welded to one side wall of the mounting member 3 to ensure the reliable connection between the connecting plate 11 and the mounting member 3.

[0047] The upper part of the connecting plate 11 is provided with a first through hole 12, as Figure 1 and Figure 2 shown. The extending direction of the first through hole 12 extends along the width direction of the vehicle frame. The welding position of the connecting plate 11 and the mounting member 3 includes not only the outer side wall of the upper part of the connecting plate 11 but also the inner side wall position of the first through hole 12 of the connecting plate 11. The first through hole 12 can make the welding position of the upper part of the connecting plate 11 and the mounting member 3 longer, increase the welding strength of the connecting plate 11 and the mounting member 3, and thus ensure the reliable installation of the airbag.

[0048] The lower part of the connecting plate 11 is provided with a second through hole 13, as Figure 1 and Figure 2 shown. The second through hole 13 can reduce the weight of the connecting plate 11.

[0049] The connecting member 1 further includes a reinforcing plate 14 connected to the connecting plate 11, as Figure 1 and Figure 2 shown. The reinforcing plate 14 is located on one side of the connecting plate 11. The reinforcing plate 14 can increase the rigidity of the connecting member 1.

[0050] The reinforcing plate 14 is arranged at an angle with the connecting plate 11, as Figure 1 and Figure 2 shown. Preferably, the reinforcing plate 14 and the connecting plate 11 are bent from the same sheet. The arrangement of the reinforcing plate 14 and the connecting plate 11 at an angle can increase the self-rigidity of the connecting member 1, and thus ensure the reliable installation of the airbag.

[0051] There are two reinforcing plates 14, as Figure 1As shown, the two reinforcing plates 14 are arranged in parallel. In the longitudinal direction of the vehicle frame, the size of the reinforcing plate 14 closer to the center position of the vehicle frame is larger than that of the other reinforcing plate 14, so as to facilitate the maintenance of the airbag under the vehicle.

[0052] A vehicle according to the present invention includes the above vehicle frame and a body shell, and both ends of the cross beam 41 are connected to the side walls of the body shell.

[0053] It is easily understood by those skilled in the art that, on the premise of no conflict, the above preferred solutions can be freely combined and superimposed.

[0054] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
