[0021] The front frame of an off-road vehicle is generally composed of a water tank upper crossbeam assembly, a water tank lower crossbeam assembly, a central support assembly, and a front pillar assembly. The traditional front pillar assembly uses multiple sheet metal parts welded into a closed beam structure, which has a large number of parts and a complex welding process; the front pillar assembly welded from sheet metal parts has poor rigidity and durability.

[0022] like Figure 1As shown, the embodiment of the utility model provides a front-end frame structure assembly, which is arranged on the front-end structure of the vehicle, the upper end of the front column assembly 1 is welded to the upper longitudinal beam 5 of the engine room, the lower end of the front column assembly 1 is welded to the lower longitudinal beam 6 of the engine room, the upper cross beam assembly 2 of the water tank is screwed on the upper longitudinal beam 5 of the engine room, and the lower cross beam assembly 3 of the water tank is welded to the lower longitudinal beam 6 of the engine room. The front-end frame structure assembly includes the upper cross beam assembly 2 and the lower cross beam assembly 3 of the water tank installed in front of the vehicle, the upper cross beam assembly 2 of the water tank and the lower cross beam assembly 3 of the water tank are connected by the central support assembly 4, and also includes a plurality of front column assemblies 1; the two ends of the front column assembly 1 are also connected to the two sides of the upper cross beam assembly 2 and the lower cross beam assembly 3 of the water tank respectively. The front column assembly 1 of the present design is formed by bending a closed square tube, which can effectively reduce the number of parts, and the manufacturing process is simple, and the cost reduction effect is obvious.

[0023] Figure 2 The front frame structure schematic diagram is shown, and the front frame is composed of a front column assembly 1, a water tank upper crossbeam assembly 2, a water tank lower crossbeam assembly 3, and a central support assembly 4. The front column assembly 1 plays a very important role in the torsional performance of the front frame structure, and therefore, the front column assembly 1 is required to have high rigidity and durability.

[0024] The front column assembly 1 is a square tube structure with closed ends. In terms of manufacturing technology, the front column assembly 1 can adopt a spliced ​​structure or an integrated structure. The present design preferably adopts a bent integrated structure with closed ends for the front column assembly 1.

[0025] The front pillar assembly 1 preferably includes a first straight pipe section 11 and a second straight pipe section 12, and the first straight pipe section 11 and the second straight pipe section 12 are connected by a curved pipe section 13, and the curved pipe section 13 is an S-shaped structure or other shapes, and has torsion resistance. The front pillar assembly 1 is also provided with installation points for riveted nuts 7 and threaded welded pipes 8.

[0026] When the front frame structure of the present design is installed on the cabin structure, the water tank upper cross beam assembly 2 is connected to the cabin upper longitudinal beam 5, and the water tank lower cross beam assembly 3 is connected to the cabin lower longitudinal beam 6. In order to facilitate installation and removal, it is preferred to screw the water tank upper cross beam assembly 2 onto the cabin upper longitudinal beam 5; and for greater stability, the water tank lower cross beam assembly 3 is welded to the cabin lower longitudinal beam 6.

[0027] A vehicle is also proposed, including the above-mentioned front-end frame structure assembly. This embodiment takes an off-road vehicle as an example, but is not limited to an off-road vehicle, and may also be other vehicles, such as trucks, buses, cars, etc.
