[0001] The present invention relates to the technical field of vehicles, and in particular to an all-terrain vehicle. Background Art

[0002] With the development of technology, all-terrain vehicles are gradually gaining recognition for their good passability and outstanding driving pleasure, and are gradually entering people's lives.

[0003] In the related technology, the air filter connected to the air intake of the engine can filter the wind about to enter the engine, so as to prevent impurities or foreign objects in the wind from entering the engine and causing damage to the engine. The air intake of the air filter is generally set at the front of the all-terrain vehicle, while the engine and air filter are generally located at the rear of the all-terrain vehicle. This will not only make the air transport pipeline longer and occupy too much space of the all-terrain vehicle, but also make the wind flow longer, increase the resistance to the wind, and when the wind enters the air filter, the wind flow rate is low, which will reduce the engine's air intake efficiency. Summary of the Invention

[0031] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0032] Reference below Figures 1-6 An all terrain vehicle 100 according to an embodiment of the present invention is described.

[0033] like Figures 1-4As shown, the all-terrain vehicle 100 according to an embodiment of the present invention includes: a frame 10, a cockpit 101, wheels (not shown in the figure), a suspension assembly (not shown in the figure), an engine 20, an air filter 30, a cargo box 40, an outer cover 60 and an intake pipe 70, wherein the cockpit 101 is arranged in the middle of the frame 10, the wheels are connected to the left and right sides of the frame 10, and the suspension assembly is connected between the wheels and the frame 10. The driver and passengers can sit in the cockpit 101, and the driver can control the all-terrain vehicle 100 in the cockpit 101. The wheels on the left and right sides of the frame 10 can be rotated to achieve normal driving of the all-terrain vehicle 100. The suspension assembly can buffer the all-terrain vehicle 100 when the all-terrain vehicle 100 is bumpy or subjected to external force. This not only improves the driving experience of the driver, but also improves the reliability of the all-terrain vehicle 100.

[0034] Furthermore, during normal driving of the all-terrain vehicle 100, the engine 20 absorbs air from the outside to maintain normal operation. Due to the rotation of the wheels or other factors, dust and foreign matter will be raised around the all-terrain vehicle 100, which will cause the air about to enter the engine 20 to contain more impurities and foreign matter. After the impurities and foreign matter in the air enter the engine 20, they will cause damage to the engine 20.

[0035] Therefore, by arranging both the engine 20 and the air filter 30 on the vehicle frame 10 and connecting the air filter 30 to the air path of the engine 20, not only can the air filter 30 fully filter the impurities and foreign matter in the air about to enter the engine 20, but also the air flowing out of the air filter 30 into the engine 20 can be made relatively clean, which can improve the service life and reliability of the engine 20. Moreover, since the engine 20 and the air filter 30 are both arranged on the vehicle frame 10, the engine 20 and the air filter 30 are arranged relatively close to each other, and the distance for the air to flow from the air filter 30 to the engine 20 is shorter, which can reduce the resistance encountered by the air in the process of flowing out of the air filter 30 into the engine 20, thereby facilitating the air intake of the engine 20.

[0036] Combine Figures 1-4As shown, the cargo box 40 is disposed on the vehicle frame 10 and is located above the engine 20 and the air filter 30. Specifically, the cargo box 40 is disposed on the vehicle frame 10, and the air filter 30 and the engine 20 are both disposed below the cargo box 40. This not only allows the engine 20 and the air filter 30 to fully utilize the space below the cargo box 40, thereby improving the space utilization rate of the all-terrain vehicle 100 and making the structure of the all-terrain vehicle 100 more compact, but also the cargo box 40 can, to a certain extent, shield and protect the engine 20 and the air filter 30, thereby preventing external forces from impacting the engine 20 and the air filter 30 and causing damage to the engine 20 and the air filter 30, thereby improving the service life and reliability of the engine 20 and the air filter 30.

[0037] Combine Figure 3-Figure 6 As shown, the outer cover 60 is disposed on the outside of the cargo box 40, and an air duct 61 is defined between the outer cover 60 and the cargo box 40, and the air duct 61 is connected to the outside. Specifically, by disposing the outer cover 60 on the outside of the cargo box 40, the outer cover 60 and the outside of the cargo box 40 can jointly define the air duct 61, and the air duct 61 can be connected to the outside, that is, the external wind can directly enter the air duct 61. In this way, a stable and strong air duct 61 can be formed on the outside of the cargo box 40 without affecting the installation and normal operation of other components, thereby optimizing the structural design of the all-terrain vehicle 100.

[0038] It should be noted that the positions where the air duct 61 is connected to the outside are on both sides of the cargo box 40 and are open toward the front. With this arrangement, during the normal driving of the all-terrain vehicle 100, the wind can enter the air duct 61 through the connecting position of the air duct 61 more quickly, thereby further improving the reliability of the air duct 61.

[0039] Further, combined with Figure 3As shown, one end of the intake duct 70 is connected to the air filter 30, and the other end of the intake duct 70 is disposed in the air duct 61. The other end of the intake duct 70 is provided with at least one air inlet 711 that communicates with the air duct 61. Specifically, the intake duct 70 can communicate with the air duct 61 through the other end. Since the other end of the intake duct 70 is provided with at least one air inlet 711 that communicates with the air duct 61, air in the air duct 61 can flow into the intake duct 70 through the air inlet 711 at the other end of the intake duct 70. After flowing through the intake duct 70 to one end of the intake duct 70, it flows into the air filter 30. The arrangement of the intake duct 70 on the all-terrain vehicle 100 fully utilizes the available space under the cargo box 40. This not only shortens the path of air flowing from the other end of the intake duct 70 to the one end, thereby improving the air intake efficiency of the air filter 30, but also makes the structural layout of the all-terrain vehicle 100 more compact. In addition, this can also ensure the stability and firmness of the installation of the intake pipe 70 on the all-terrain vehicle 100.

[0040] Therefore, by arranging the outer cover 60 on the outside of the cargo box 40, the outer cover 60 and the cargo box 40 jointly define the air duct 61, the air duct 61 is connected to the outside, and the other end of the air intake pipe 70 is connected to the air duct 61. The wind in the air duct 61 can enter the air filter 30 through the other end of the air intake pipe 70. This can reduce the path of the wind flowing from the other end of the air intake pipe 70 into the air filter 30, thereby improving the air intake efficiency of the air filter 30.

[0041] Combine Figure 3 and Figure 5 As shown, the outer cover 60 is disposed on the rear side of the cargo box 40, and an air duct 61 defined between the outer cover 60 and the cargo box 40 is located on the rear side of the cargo box 40. At least one air inlet 711 is located in the air duct 61. Specifically, by disposing the outer cover 60 on the rear side of the cargo box 40, the air duct 61 between the outer cover 60 and the cargo box 40 is located on the rear side of the cargo box 40. Since the air filter 30 and the engine 20 are also located on the rear side of the vehicle frame 10, the air duct 61 is relatively close to the air filter 30. The air inlet 711 at the other end of the intake pipe 70 is located in the air duct 61. This shortens the distance that air travels from the air duct 61 to the air filter 30, thereby further improving the air intake efficiency of the air filter 30 and thereby improving the reliability of the all-terrain vehicle 100.

[0042] Combine Figure 6As shown, the ATV 100 may also primarily include taillights 50, which are disposed on the rear side of the cargo box 40 and connected to the outer cover 60. There are two taillights 50, one located on either side of the air inlet 711. Specifically, the taillights 50 are disposed on the rear side of the cargo box 40 and connected to the outer cover 60. This allows the outer cover 60 to protect the taillights 50 while providing stable light transmission for the taillights 50. Furthermore, the two taillights 50 are located on either side of the air inlet 711, allowing the air inlet 711 to fully utilize the space between the two taillights 50. This not only improves space utilization and makes the ATV 100 more compact, but also prevents the placement of the air inlet 711 from interfering with the installation of other components on the ATV 100, making the placement of the air inlet 711 more reasonable.

[0043] Combine Figure 1-Figure 3 As shown, the cargo box 40 may mainly include a rear panel 41 and side panels 42 connected to the rear panel 41, and auxiliary air inlets 4521 communicating with the air duct 61 are provided on the rear panel 41 and / or the side panels 42. Specifically, the rear panel 41 of the cargo box 40 is located at the rear side of the cargo box 40, and the side panels 42 of the cargo box 40 are located on both sides of the cargo box 40 and are connected to the rear panel 41. By providing the auxiliary air inlets 4521 on the rear panel 41 and / or the side panels 42 of the cargo box 40, and making the auxiliary air inlets 4521 communicate with the air duct 61, since during the normal driving of the all-terrain vehicle 100, there will be high-speed wind flowing from front to back in the cargo box 40, and the auxiliary air inlets 4521 are communicated with the air duct 61, the auxiliary air inlets 4521 are communicated with the air duct 61. Or an auxiliary air inlet 4521 is set on the side panel 42, so that the high-speed wind flowing in the cargo box 40 enters the air duct 61 through the auxiliary air inlet 4521. On the premise that the air duct 61 itself is connected to the outside, the air intake volume and the wind flow speed of the air duct 61 can be further increased, thereby further increasing the air intake volume of the intake pipe 70 and the flow rate of the wind flowing in the intake pipe 70 to the air filter 30, thereby further improving the reliability of the air duct 61 and the intake pipe 70.

[0044] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, the other end of the air intake duct 70 is provided with a tube body 71, and an air inlet 711 is connected to the tube body 71 and faces the left and right sides of the all-terrain vehicle 100. Specifically, the air inlet 711 is connected to the tube body 71 at the other end of the air intake duct 70 and faces the left and right sides of the all-terrain vehicle 100. The air on the left and right sides of the tube body 71 enters the tube body 71 stably and continuously through the auxiliary air inlets 4521 on the left and right sides of the tube body 71, and then flows into the air intake duct 70 together, and then flows through the air intake duct 70 to the air filter 30. This can further improve the air intake reliability of the air intake duct 70 while making the structure of the air intake duct 70 simple and direct, and can prevent the air from flowing through the air intake duct 70 from having a long or complex path, thereby further improving the air intake efficiency of the air filter 30.

[0045] Combine Figure 3 、 Figure 4 and Figure 6 As shown, the auxiliary air inlet 4521 is provided with an air inlet grille 45211. Specifically, since the cargo box 40 generally needs to be loaded with cargo, the wind on the cargo box 40 blows from front to back and, in the process of entering the air duct 61 through the auxiliary air inlet 4521, may blow larger foreign objects toward the auxiliary air inlet 4521. Therefore, by providing the air inlet grille 4521 at the auxiliary air inlet 4521, the air inlet grille 45211 can separate larger foreign objects from the air duct 61, preventing larger foreign objects from entering the air duct 61 through the auxiliary air inlet 4521 and damaging components in the air duct 61, thereby making the air duct 61 more stable and reliable.

[0046] Combine Figure 1 and Figure 2 As shown, the cargo box 40 may primarily include a bottom plate 43, which is located at the bottom of the cargo box 40. The tube body 71 is higher than the bottom plate 43 in the height direction and lower than the highest edge of the rear panel 41. Specifically, the tube body 71 is positioned higher than the bottom plate 43 and lower than the highest edge of the rear panel 41, so that the tube body 71 is positioned between the upper and lower ends of the rear panel 41. This allows the rear panel 41 to provide a certain degree of shielding and protection for the tube body 71, preventing the tube body 71 from protruding from the rear panel 41 in the height direction, which could cause the tube body 71 to easily rub against external objects. This further optimizes the structural design of the air intake duct 70.

[0047] Combine Figure 3 、 Figure 5 and Figure 6As shown, the bottom plate 43 defines a maintenance opening 421. The cargo box 40 may further include a maintenance cover 46, which is openably and closably disposed on the maintenance opening 421. At least one of the engine 20 and the air filter 30 is disposed directly below the maintenance opening 421. Specifically, by defining the maintenance opening 421 on the bottom plate 43 of the cargo box 40 and providing the maintenance cover 46 with an openable and closable position thereon, the maintenance cover 46 can reliably seal the maintenance opening 421 during normal operation of the all-terrain vehicle 100. This ensures that cargo loaded in the cargo box 40 is stable, prevents cargo leakage, and ensures the reliability of the cargo box 40.

[0048] Furthermore, at least one of the engine 20 and the air filter 30 is arranged directly below the maintenance port 421. When at least one of the engine 20 and the air filter 30 needs maintenance, the maintenance cover 46 can be directly removed from the cargo box 40, thereby opening the maintenance port 421 on the cargo box 40. With this arrangement, maintenance personnel can repair at least one of the engine 20 and the air filter 30 from top to bottom through the maintenance port 421, which can facilitate the operation of maintenance personnel and reduce the difficulty of maintenance.

[0049] Furthermore, a tool box is provided between the bottom of the cargo box 40 and the air filter 30 or the engine 20. This not only allows the tool box to fully utilize the space between the bottom of the cargo box 40 and the air filter 30 or the engine 20, but also allows tools to be directly taken from the tool box to repair the air filter 30 or the engine 20 during maintenance, which can further facilitate the maintenance of the air filter 30 or the engine 20.

[0050] Furthermore, the outer cover 60 is detachably connected to the cargo box 40. Specifically, by detachably connecting and fixing the outer cover 60 to the cargo box 40, the outer cover 60 can be easily removed while ensuring a stable and secure connection to the cargo box 40, thereby facilitating the repair and replacement of the taillight 50 and the air intake duct 70 in the air duct 61. This can facilitate the user's subsequent maintenance of the all-terrain vehicle 100, thereby improving the user's experience.

[0051] Combine Figure 3-Figure 6As shown, the baffle 45 can mainly include: a connecting portion 451, an air inlet portion 452 and a covering portion 453, the connecting portion 451 is connected to the notch 44, the air inlet portion 452 is connected between the connecting portion 451 and the covering portion 453, the air inlet portion 452 is provided with an auxiliary air inlet 4521, and faces the front side of the all-terrain vehicle 100, and the rear of the covering portion 453 is connected to the outer cover 60. Specifically, the baffle 45 can be stably and firmly installed on the cargo box 40 as a whole by first connecting the connecting portion 451 and the notch 44, and then the air inlet portion 452 is connected between the connecting portion 451 and the covering portion 453. By providing an auxiliary air inlet 4521 on the air inlet portion 452, and making the auxiliary air inlet 4521 face the front side of the all-terrain vehicle 100, the wind flowing from front to rear in the cargo box 40 can smoothly and stably pass through the auxiliary air inlet 4521 into the air duct 61, so that the structural setting of the air inlet portion 452 can be reasonable and simple.

[0052] Furthermore, the rear part of the covering portion 453 is connected to the outer cover 60, which not only ensures the stability of the installation of the outer cover 60, but also prevents the connection between the outer cover 60 and the baffle 45 from affecting the air intake of the auxiliary air inlet 4521 on the air inlet portion 452, thereby further optimizing the structural design of the baffle 45.
