[0034] The present invention will be further described below with reference to specific embodiments:

[0035] A split-type vehicle frame includes a chassis assembly 1, a front suspension assembly 2, and a rear suspension assembly 3. The chassis assembly 1 is used to mount a floor plate, on which a driver's seat, a middle seat, and a rear seat can be mounted for users to sit on. The front suspension assembly 2 is used to mount a front swingarm assembly, which connects the front wheel 4 and a steering wheel for driving the front wheel 4. The rear suspension assembly 3 is used to mount the rear wheel 5.

[0036] like Figure 1 , 2 As shown in this patent, the chassis assembly 1 includes a left longitudinal beam 11 and a right longitudinal beam 12, with a longitudinal beam connector 16 between them. The chassis assembly 1 is used to mount a base plate. The left longitudinal beam 11 and the right longitudinal beam 12 have square cross-sections and can be made of aluminum or steel. The longitudinal beam connector 16 has U-shaped connecting seats at both ends, which are fastened to the left and right longitudinal beams 11 and 12 to achieve a detachable connection. After the longitudinal beam connector 16 is installed, the left and right longitudinal beams 11 and 12 are connected as a whole, and a base plate can be mounted on the left and right longitudinal beams 11 and 12 to support the seats or various other components in the vehicle. The chassis assembly 1 can also be used to install some seat frames, on which panels and cushions can be set for people to sit. The seat frames include at least a middle seat frame 17 and a driver's seat frame 18. In this patent, the middle seat frame 17 and the driver's seat frame 18 are seat-shaped brackets obtained by splicing together several rods and are directly fixed to the longitudinal beam connector 16 by fasteners. The above seat frame structure realizes the modular production of the seat part, thereby accelerating the manufacturing efficiency and transportation efficiency.

[0037] The front ends of the left longitudinal beam 11 and the right longitudinal beam 12 are provided with the front suspension assembly 2. The front suspension assembly 2 includes a front rocker arm mounting bracket 21, which is used to mount the front rocker arm assembly. Figure 2 , 3 As shown in this patent, the front ends of the left longitudinal beam 11 and the right longitudinal beam 12 are tightened towards the inside of each other, and a horizontally placed front bumper bracket 219 is detachable at its end. The front bumper bracket 219 is used to install the bumper.

[0038] The front rocker arm mounting bracket 21 includes a front shock absorber mounting front plate 211 and a front shock absorber mounting rear plate 212. A front rocker arm mounting front plate 213 and a front rocker arm mounting rear plate 214 are respectively provided outside the front shock absorber mounting front plate 211 and the front shock absorber mounting rear plate 212. The height of the front rocker arm mounting front plate 213 and the front rocker arm mounting rear plate 214 is slightly lower than that of the front shock absorber mounting front plate 211 and the front shock absorber mounting rear plate 212. Bracket mounting slots 217 are provided on the left and right sides of the front shock absorber mounting front plate 211, the front shock absorber mounting rear plate 212, the front rocker arm mounting front plate 213, and the front rocker arm mounting rear plate 214. The bracket mounting slots 217 are square. Figure 3 , 4As shown, square front rocker arm mounting seats 218 are provided in the bracket mounting slots 217 on both sides of the front shock absorber mounting front plate 211, the front shock absorber mounting rear plate 212, the front rocker arm mounting front plate 213, and the front rocker arm mounting rear plate 214. In this embodiment, the two front rocker arm mounting seats 218 are welded together with the front shock absorber mounting front plate 211, the front shock absorber mounting rear plate 212, the front rocker arm mounting front plate 213, and the front rocker arm mounting rear plate 214, respectively. The cross-section of the front rocker arm mounting seat 218 is U-shaped and is fastened to the corresponding left longitudinal beam 11 and right longitudinal beam 12. Fasteners are provided on the front rocker arm mounting seat 218 to fix it to the left longitudinal beam 11 or the right longitudinal beam 12, thereby fixing the front shock absorber mounting front plate 211, the front shock absorber mounting rear plate 212, the front rocker arm mounting front plate 213, and the front rocker arm mounting rear plate 214 between the left longitudinal beam 11 and the right longitudinal beam 12.

[0039] A rocker arm mounting portion 215 is formed between the front shock absorber mounting plate 211 and the front rocker arm mounting plate 213, and between the front shock absorber mounting rear plate 212 and the front rocker arm mounting rear plate 214. A shock absorber mounting portion 216 is formed between the front shock absorber mounting plate 211 and the front shock absorber mounting rear plate 212. Figure 3 , 4 As shown, the shock absorber mounting portion 216 and the rocker arm mounting portion 215 are actually hollow parts, which can be formed between the adjacent panels. Two rocker arm mounting portions 215 are formed vertically between the front shock absorber mounting front plate 211 and the front rocker arm mounting front plate 213, and between the front shock absorber mounting rear plate 212 and the front rocker arm mounting rear plate 214, respectively. The front rocker arm assembly includes a Y-shaped rocker arm, with two rocker arms 6 connected vertically to each front wheel 4. One end of the rocker arm 6 is located in the front and rear rocker arm mounting portions 215 and is connected by a rotating shaft, while the other end of the rocker arm is connected to the front wheel 4. The front rocker arm assembly also includes a front shock absorber 7, which is connected in the shock absorber mounting portion 216, and the other end is connected to the rocker arm. Similarly, the other front wheel 4 is also connected through the same structure.

[0040] In summary, the front rocker arm mounting bracket 21 in this patent is connected to the front end of the chassis assembly 1 in a modular manner. The front rocker arm mounting bracket 21 can be disassembled separately during transportation, and its modular manufacturing effectively reduces manufacturing and transportation costs. Furthermore, the front ends of the left longitudinal beam 11 and right longitudinal beam 12 are well-convex towards each other, leaving space for the front wheel 4, making the entire front suspension assembly 2 more compact.

[0041] Furthermore, the front suspension assembly 2 also includes a front cross brace bracket 22, which supports the vehicle's roof and front end shell. Specifically, the front cross brace bracket 22 includes a left crossbar support 221 and a right crossbar support 222 connected to the left longitudinal beam 11 and the right longitudinal beam 12, respectively. A front crossbar support 223 connects the left crossbar support 221 and the right crossbar support 222, and the two ends of the front crossbar support 223 are connected to a left roof support column 224 and a right roof support column 225, respectively. Figure 5 As shown, the left support 221 of the crossbar includes two columns fixed to the left longitudinal beam 11, one in front and one behind. These columns are offset outwards, extending to the same level as the wheel. A crossbar support seat 2231 is welded to the top of each column. Similarly, the right support 222 consists of two columns fixed to the right longitudinal beam 12, each also bearing the crossbar support seat 2231. The front crossbar support 223 is fixed to the two crossbar support seats 2231 and connected to them using fasteners. The two ends of the front crossbar support 223 are respectively connected to the left support column 224 and the right support column 225 of the roof, as shown... Figure 2 , 5 As shown, the left support column 224 and the right support column 225 of the roof are fixed to the left and right ends of the front cross brace 223 by an angle iron piece, which extends to the rear side of the vehicle.

[0042] Furthermore, the front suspension assembly 2 also includes a brake pedal mounting bracket 23, which has a brake pedal mounting seat 231 for fixing to the left support 221 and the right support 222 of the crossbar. Figure 5 As shown, the brake pedal mounting bracket 23 is a grid-like frame formed by welding together several rods. On both sides of the brake pedal mounting bracket 23 are brake pedal mounting seats 231 with a "U"-shaped cross-section. The brake pedal mounting seats 231 are fastened to the columns in the left support 221 and right support 222 of the two crossbars, thereby achieving fixation. The brake pedal mounting bracket 23 is used to mount the brake pedal, and its grid-like structure allows the steering wheel to pass through into the driver's cab.

[0043] The left longitudinal beam 11 and the right longitudinal beam 12 are respectively provided with a left chassis extension longitudinal beam 13 and a right chassis extension longitudinal beam 14. Supporting connecting rods 15 are provided between the left chassis extension longitudinal beam 13 and the right chassis extension longitudinal beam 14 and the left support column 224 and the right support column 225 of the roof, respectively. Figure 2As shown, the left chassis extension longitudinal beam 13 and the right chassis extension longitudinal beam 14 are located outside the left longitudinal beam 11 and the right longitudinal beam 12, and are U-shaped to widen the entire chassis assembly 1. In order to increase the stability of the vehicle, this patent provides the support link 15. The two ends of the support link 15 can be fixed between the left chassis extension longitudinal beam 13 and the right chassis extension longitudinal beam 14 and the left roof support column 224 and the right roof support column 225 by fasteners.

[0044] like Figure 6 , 7 As shown, the rear ends of the left longitudinal beam 11 and the right longitudinal beam 12 are offset upwards, forming a space below them for mounting the rear wheel 5. A rear suspension assembly 3 is provided on the rear ends of the left longitudinal beam 11 and the right longitudinal beam 12. The rear suspension assembly 3 includes a rear support rod 31, and a rear frame 32 for connecting to the rear wheel 5 is connected below the rear support rod 31. Two "U"-shaped mounting seats are provided at the left and right ends of the rear support rod 31, which fix the left and right ends of the rear support rod 31 to the left and right longitudinal beams 11 and 12. The rear frame 32 consists of several rods fixed below the rear support rod 31, extending downwards to connect to the wheel. Specifically, a rear shock absorber 8 is connected to the rear ends of the left longitudinal beam 11 and the right longitudinal beam 12. The lower end of the rear shock absorber 8 is connected to the rear frame 32 and the rear rotating rod connecting the rear wheel 5, thus connecting the rear shock absorber 8 and the rear wheel 5 through the rear frame 32.

[0045] Furthermore, it also includes a rear seat frame 33, which has two rear seat mounting brackets 331 respectively connected to the left longitudinal beam 11 and the right longitudinal beam 12. Figure 7 As shown, the rear seat frame 33 is specifically a bracket assembled into a seat shape by connecting rods. A U-shaped rear seat fixing seat 331 is provided at its lower end, through which the rear seat frame 33 is fixed to the left longitudinal beam 11 and the right longitudinal beam 12. The rear seat frame 33 is used to mount the rear seat.

[0046] Furthermore, the rear seat frame 33 has a left connecting C-pillar 34 and a right connecting C-pillar 35 on both sides, which are connected to the left roof support column 224 and the right roof support column 225, respectively. Figure 6 , 7 As shown, connecting joints are welded to the left and right ends of the rear support rod 31. The connecting joints connect the two upward-extending left connecting C-pillar 34 and right connecting C-pillar 35.
