[0044] As described in the background technology, the current all-terrain vehicles have poor maneuverability and stability. The inventors have found that the reason for this problem is that the fuel tank of the all-terrain vehicle is arranged at the top of the frame, which causes the center of gravity of the all-terrain vehicle to be higher, affecting the driving stability; or along the driving direction of the all-terrain vehicle, the fuel tank is arranged at the rear end of the frame, causing the center of gravity of the all-terrain vehicle to be moved backward, affecting operability.

[0045] In response to the above technical problems, an embodiment of the present application provides an all-terrain vehicle. By setting the fuel tank in the middle space and on the chassis, not only the center of gravity height of the all-terrain vehicle can be lowered, but the center of gravity of the all-terrain vehicle is closer to the middle, which is beneficial to improving the stability and maneuverability of the all-terrain vehicle.

[0046] Furthermore, by arranging the power system in the rear space of the frame and on the chassis of the all-terrain vehicle, the center of gravity of the all-terrain vehicle is more balanced in the front and rear directions, thereby improving the maneuverability of the all-terrain vehicle.

[0047] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0048] To facilitate the description of the all-terrain vehicle provided in the embodiment of the present application, the coordinate system of the attached drawings is first described. The X-axis direction is the first direction, which can be defined as the driving direction of the all-terrain vehicle; the Y-axis direction is the second direction, which can be defined as the width direction of the all-terrain vehicle; and the Z-axis direction is the third direction, which can be defined as the height direction of the all-terrain vehicle.

[0049] like Figure 1As shown, the all-terrain vehicle 100 provided in the embodiment of the present application includes a frame 10, wheels, a steering system, a power system and a fuel tank 20, wherein the frame 10 is a frame structure and has a storage space. Along the first direction, the storage space of the frame 10 is divided into a front space 10a, a middle space 10b and a rear space 10c, and the fuel tank 20 is arranged in the middle space 10b and is located on the chassis of the all-terrain vehicle 100, wherein the chassis of the all-terrain vehicle 100 is configured as a load-bearing structure installed at the bottom of the frame 10.

[0050] The power system is disposed in the rear space 10c and is located on the chassis of the all-terrain vehicle 100. The power system is used to provide driving power to the all-terrain vehicle 100, and the power system includes an engine 30, which is connected to a fuel tank 20, and the fuel tank 20 contains fuel, which is further transmitted to the combustion chamber of the engine 30.

[0051] The wheels include a front wheel and a rear wheel. The front wheel can be installed at the front end of the frame 10 through a front wheel support, and the rear wheel can be installed at the rear end of the frame 10 through a rear wheel support. The power generated by the power system can be transmitted to the wheels through the transmission system and drive the wheels to rotate.

[0052] For example, the transmission system includes a front transmission shaft, a front axle assembly, a rear axle assembly, and a rear transmission shaft, wherein one end of the front transmission shaft is transmission-connected to the engine 30 to receive power; the other end of the front transmission shaft is transmission-connected to the front axle assembly, and transmits power to the front wheel through the front axle assembly to rotate the front wheel. One end of the rear transmission shaft is transmission-connected to the engine 30 to receive power; the other end of the rear transmission shaft is transmission-connected to the rear axle assembly, and transmits power to the rear wheel through the rear axle assembly to rotate the rear wheel.

[0053] Furthermore, a steering system is disposed in the front space 10a of the frame 10, and the steering system is used to control the driving direction of the wheels. For example, the steering system includes a steering rod and a steering wheel, one end of the steering rod is connected to the steering wheel, and the other end of the steering rod is connected to the steering gear, and the steering of the front wheels is controlled by the steering gear, thereby controlling the driving direction of the all-terrain vehicle 100.

[0054] In the related art, the fuel tank of the all-terrain vehicle is arranged on the top of the frame, which causes the center of gravity of the all-terrain vehicle to be higher, affecting driving stability; or the fuel tank is arranged at the rear end of the frame along the driving direction of the all-terrain vehicle, causing the center of gravity of the all-terrain vehicle to be backward, affecting operability.

[0055] However, the embodiment of the present application arranges the frame 10 reasonably and arranges the fuel tank 20 in the middle space 10b and on the chassis, so as to reduce the height of the center of gravity of the all-terrain vehicle 100 and make the center of gravity of the all-terrain vehicle 100 closer to the middle, which is conducive to improving the stability and maneuverability of the all-terrain vehicle 100. Furthermore, the power system is arranged in the rear space 10c of the frame 10 and on the chassis of the all-terrain vehicle 100, so as to make the center of gravity of the all-terrain vehicle 100 more balanced in the front and rear directions, so as to improve the maneuverability of the all-terrain vehicle 100.

[0056] like Figure 2 As shown, the vehicle frame 10 in the embodiment of the present application includes two first main beams 11, two second main beams 12 and a plurality of support beams; wherein the first main beams 11 and the second main beams 12 may be weldable square tubes or round tubes. Along the third direction, the two first main beams 11 are located at the top of the vehicle frame 10, the two second main beams 12 are located at the bottom of the vehicle frame 10, and the two first main beams 11 correspond to the two second main beams 12 respectively, that is, a first main beam 11 is arranged above each second main beam 12 at intervals.

[0057] Multiple support beams are arranged along the third direction, each support beam is connected between the corresponding first main beam 11 and the second main beam 12, and each support beam and the first main beam 11 and the second main beam 12 respectively enclose a front space 10a, a middle space 10b and a rear space 10c.

[0058] Specifically, the plurality of support beams include a first support beam 13 and a second support beam 14, wherein the first support beam 13 and the second support beam 14 may be weldable square tubes or round tubes, the first support beam 13 and the second support beam 14 are arranged opposite to each other along a first direction, and the first support beam 13 is located in front of the second support beam 14. Along the third direction, both ends of the first support beam 13 and the second support beam 14 are respectively connected between the first main beam 11 and the second main beam 12 and enclose a middle space 10b.

[0059] It should be noted that the connection method between the first support beam 13 and the first main beam 11 and the connection method between the second support beam 14 and the second main beam 12 include but are not limited to welding or connection by fasteners, which is not limited in the embodiment of the present application. Preferably, welding is used to improve the structural strength of the entire frame 10.

[0060] Two first main beams 11 are arranged at intervals along the second direction, and two second main beams 12 are arranged at intervals along the second direction. Each first main beam 11 corresponds to one second main beam 12, and along the third direction, the first main beam 11 is arranged above the second main beam 12. The first main beam 11 and the second main beam 12 extend along the first direction respectively, and the front end of the first main beam 11 is bent downward along the third direction to form a bending portion 111. The bending portion 111 extends obliquely to the front end of the second main beam 12 and is connected to the second main beam 12, so that the bending portion 111 of the first main beam 11 and the second main beam 12 and the first support beam 13 enclose a front space 10a. Similarly, the connection method of the bending portion 111 of the first main beam 11 and the second main beam 12 includes but is not limited to welding or connection through fasteners, and the embodiment of the present application does not limit this. Preferably, welding is used to improve the structural strength of the entire frame 10.

[0061] Furthermore, the plurality of support beams further include a third support beam 15, which includes a special-shaped structure formed by splicing a plurality of support tubes, and the support tubes may be weldable square tubes and round tubes. The third support beam 15 and the second support beam 14 are arranged opposite to each other along the first direction, and the third support beam 15 is located at the rear side of the second support beam 14; along the third direction, the two ends of the third support beam 15 are respectively connected to the first main beam 11 and the second main beam 12, and the third support beam 15, the second support beam 14, the first main beam 11 and the second main beam 12 enclose a rear space 10c.

[0062] Similarly, the splicing method of the multiple support tubes in the third support beam 15, and the connection method of the third support beam 15 with the first main beam 11 and the second main beam 12 include but are not limited to welding or connection by fasteners, which are not limited in the embodiment of the present application. Preferably, welding is used to improve the structural strength of the entire frame 10.

[0063] On the basis of the above embodiment, the first support beam 13 in the embodiment of the present application is connected obliquely between the first main beam 11 and the second main beam 12. For example, along the third direction, the first support beam 13 gradually tilts toward the rear side from the upper end to the bottom end, and the second support beam 14 gradually tilts toward the front side from the upper end to the bottom end. The first support beam 13, the second support beam 14, part of the first main beam 11, and part of the second main beam 12 form an inverted trapezoidal structure. In this way, the structural strength of the middle space 10b and the structural strength of the entire vehicle can be improved.

[0064] Along the third direction, the bottom of the fuel tank 20 is detachably connected to the two second main beams 12, so that the fuel tank 20 is installed on the chassis of the all-terrain vehicle 100. For example, first connecting seats are respectively provided on both sides of the bottom of the fuel tank 20, and are detachably connected to the two second main beams 12 through the first connecting seats.

[0065] Further, along the first direction, at least one side of the fuel tank 20 is detachably connected to the first support beam 13 or the second support beam 14. For example, along the first direction, the front side and / or the rear side of the fuel tank 20 are respectively provided with a second connection seat, and the fuel tank 20 is detachably connected to the first support beam 13 and / or the second support beam 14 through the second connection seat. Preferably, the second connection seats are respectively provided on both sides of the fuel tank 20, and are detachably connected to the first support beam 13 and the second support beam 14 through the second connection seats, so as to improve the installation stability of the fuel tank 20.

For example, the all-terrain vehicle 100 further includes a carrier, which is used to fix the engine 30, that is, the engine 30 is installed on the carrier, and is further detachably connected to the two second main beams 12 through the carrier.

[0067] In the embodiment of the present application, an anti-collision beam 16 is further provided in the rear space 10c. The anti-collision beam 16 is provided obliquely, and the two ends of the anti-collision beam 16 are respectively detachably connected to the first main beam 11 and the second main beam 12. In this way, along the second direction, the anti-collision beam 16 is located on both sides of the engine 30, which can not only protect the engine 30, but also improve the structural strength of the entire frame 10.

[0068] Preferably, both ends of the anti-collision beam 16 are detachably connected to the first main beam 11 and the second main beam 12, respectively, and the anti-collision beam 16 is connected to the outer sides of the first main beam 11 and the second main beam 12 along the second direction. With such an arrangement, it is convenient to install the anti-collision beam 16 on the vehicle frame 10 after the engine 30 is arranged in the rear space 10c, and it is convenient to install and remove the engine 30.

[0069] In one embodiment, the first main beam 11 is provided with a first mounting seat, and the second main beam 12 is provided with a second mounting seat, the first mounting seat is used to mount the upper end of the anti-collision beam 16, and the second mounting seat is used to mount the lower end of the anti-collision beam 16. The mounting surfaces of the first mounting seat and the second mounting seat are arranged toward the outside along the second direction, and each mounting surface has a mounting point, so that the two ends of the anti-collision beam 16 can be detachably connected to the first mounting seat and the second mounting seat. For example, the anti-collision beam 16 can be connected to the first mounting seat and the second mounting seat by bolts.

[0070] It should be noted that the all-terrain vehicle 100 in the embodiment of the present application also includes a plurality of connecting beams 17. For example, the connecting beams 17 are horizontally arranged along the first direction and can connect the first support beam 13 and the bending portion 111 of the first main beam 11; or, the connecting beams 17 are horizontally arranged along the second direction and can connect the two first support beams 13; or, the connecting beams 17 are inclined and can connect the first main beam 11 and the first support beam 13. The embodiment of the present application does not impose any restrictions on this. A plurality of connecting beams 17 are arranged on the frame 10, which can improve the overall structural strength of the frame 10.

For the convenience of describing the embodiment, one of the rear left suspension 40b and the rear right suspension 40a is taken as an example for description.

[0073] In the embodiment of the present application, the rear right suspension 40a includes an upper rocker arm 41 and a lower rocker arm 42, wherein the upper rocker arm 41 and the lower rocker arm 42 are arranged upward and downward along the third direction, and the frame 10 is provided with a rear wheel support 50 and a rear suspension mounting plate 18. One end of the upper rocker arm 41 is connected to the rear suspension mounting plate 18, and two first connection points are formed between the upper rocker arm 41 and the rear suspension mounting plate 18; the other end of the upper rocker arm 41 is connected to the upper part of the rear wheel support 50, and two second connection points are formed.

[0074] Furthermore, in the first direction, the length L1 between the two first connection points is greater than the length L2 between the two second connection points. In this way, the connection length L1 between the upper rocker arm 41 and the frame 10 is greater than the connection length L2 between the upper rocker arm 41 and the rear wheel support 50, which can improve the reliability and stability of the connection between the rear suspension and the frame 10.

[0075] On the basis of the above embodiment, the lower rocker arm 42 in the embodiment of the present application includes a first arm 421 and a second arm 422, wherein one end of the first arm 421 and the second arm 422 are connected to the lower part of the rear wheel support 50, one end of the first arm 421 is connected to the rear suspension mounting plate 18, and two third connection points are formed. The other end of the second arm 422 is connected to the frame 10.

[0076] The width of the rear suspension mounting plate 18 gradually decreases from top to bottom along the third direction, and the upper rocker arm 41 and the first arm 421 are respectively connected to one rear suspension mounting plate 18, and form a first connection point and a third connection point respectively. Along the first direction, the length L1 between the two first connection points is greater than the length L3 between the two third connection points. Such an arrangement can improve the shock absorption performance of the rear suspension.
