This application is based on and claims priority to Chinese Application No. 202120374068.1, filed on Feb. 10, 2021, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of motor vehicles and, more particularly, to an all-terrain vehicle.
Saddle-type all-terrain vehicles in the related art include exposed fuel tanks that are usually arranged in front of and above seats. The higher position of the fuel tanks causes the center of gravity of the vehicles to be high, easily making the vehicles unsteady. Moreover, the fuel tanks externally arranged are exposed to the sun in the open air, which is a safety risk.
An all-terrain vehicle includes: a frame including a seat cushion and a steering handle; an engine including a crankcase arranged on the frame; an air filter arranged on the frame and coupled to the engine through an engine intake pipe; and a fuel tank arranged on the frame, wherein a projection of the fuel tank at least partially overlaps with a projection of the crankcase of the engine in a plane perpendicular to a longitudinal central symmetry plane of the all-terrain vehicle.
Another all-terrain vehicle includes: a frame including a seat cushion and a steering handle; an engine including a crankcase arranged on the frame; an air filter arranged on the frame and coupled to the engine through an engine intake pipe; and a fuel tank arranged on the frame, and located between the engine and the air filter and in front of the engine and the air filter.
Embodiments of the present disclosure will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure rather than limit the present disclosure.
Referring to the drawings, embodiments of the present disclosure provide an all-terrain vehicle including: a frame 10, an engine 20, an air filter 30, and a fuel tank 40. The frame 10 includes a seat cushion 11 and a steering handle 12. The engine 20 is arranged on the frame 10 and provides power, and the engine includes a crankcase arranged on the frame 10. The air filter 30 is arranged on the frame 10 and is coupled to the engine 20 through an engine intake pipe. The fuel tank 40 is arranged on the frame 10 and coupled to the engine 20. In a plane perpendicular to a longitudinal central symmetry plane of the all-terrain vehicle, a projection of the fuel tank 40 at least partially overlaps with a projection of the crankcase of the engine 20. Such an arrangement can lower a center of gravity of the fuel tank and make the vehicle more stable during driving.
The fuel tank 40 may be located in front of the engine 20. In some embodiments, the fuel tank 40 may be located in front of and above the engine 20. In other embodiments, the fuel tank 40 may be located between the engine 20 and a front wheel 60 of the all-terrain vehicle, and the center of gravity of the fuel tank 40 is above a center of the front wheel 60. Thus, the spatial arrangement of various components of the all-terrain vehicle can be optimized and the stability of the all-terrain vehicle during driving can be further improved.
In a specific embodiment, the air filter 30 is located between the seat cushion 11 and the steering handle 12, and the air filter 30 at least partially shields an upper surface of the fuel tank 40. The weight of the air filter 30 is lighter than that of the fuel tank 40, and arranging the lighter air filter 30 in a higher position is conducive to the lowering of the center of gravity of the whole vehicle. Further, since the air filter 30 at least partially shields the upper surface of the fuel tank 40, it is possible to diminish or prevent the fuel tank 40 from being exposed, reducing or avoiding exposure to the sun, and lowering the safety risk.
Further, the fuel tank 40 is located the front of and below the air filter 30, and the lowered position of the fuel tank 40 facilitates the lowering of the center of gravity of the entire vehicle and improves the stability of the entire vehicle. In some embodiments, the position of the seat cushion 11 is higher than the position of the fuel tank 40, further lowering the center of gravity of the fuel tank 40.
In a specific embodiment, the center of gravity of the fuel tank 40 is located in front of and below a center of gravity of the air filter 30. That is, the fuel tank 40 is located below and forward of the air filter 30.
A decorative cover 31 is arranged on a top of the air filter 30 and covers the air filter 30. The decorative cover 31 is smoothly transitioned to the seat cushion 11. The decorative cover 31 protects the air filter 30 and is able to cover all components below the decorative cover 31 (at least including a partial structure of the fuel tank 40) in all directions. The smooth transition described here means that adjacent edges of the two components are at the same height.
In a specific embodiment, a refueling port 41 of the fuel tank 40 is located on a left or right side of the decorative cover 31. As shown in
Referring to
Further, the decorative cover 31 includes a holding space that can be selectively opened and closed. The holding space can be used to mount electrical terminals, realizing the concealed arrangement of the electrical terminals and preventing dust or rain from affecting the performance of the electrical terminals, and can also be used for storage to make it convenient for drivers to store some items.

Referring to
The fuel tank 40 and the frame 10 at least have a first connection point 43, a second connection point 44, and a third connection point 45. The first connection point 43 and the second connection point 44 are located on an upper part of the fuel tank 40, and the third connection point 45 is located on a lower part of the fuel tank 40. The three connection points ensures the stable installation of the fuel tank 40.
In an embodiment, a horizontal cross-section of the fuel tank 40 decreases from top to bottom, so that a shape of the fuel tank 40 allows the fuel tank to be adaptively fitted to the frame 10. The horizontal cross-section herein refers to the horizontal cross-section of the fuel tank 40 when mounted to the frame. In some embodiments, an overall shape of the fuel tank 40 in a mounted state is approximately an inverted triangle, and the fuel tank is arranged as far forward as possible on the premise of not interfering with front wheels 60.
In conclusion, for the all-terrain vehicle provided by the embodiments of the present disclosure, based on the concealed design of the fuel tank, the mounting position of the fuel tank is lowered and thus the center of gravity of the whole vehicle is lowered, making the vehicle more stable during driving. Further, the fuel tank is no longer exposed, reducing the safety hazards arising from the fuel tank being exposed to the sun, and reducing the volatilization of gasoline due to high temperature.
