Description

Technical Field

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

[0002] An all-terrain vehicle (ATV) is a vehicle designed for off-road use. For example, an ATV can be used in deserts, jungles, and other environments. The ATV's powertrain includes the engine and continuously variable transmission (CVT). Because off-road conditions are often harsh, and the engine and CVT require air to operate, dust and other impurities in the air can enter the engine and CVT during off-road use, increasing wear and tear on the engine and CVT, ultimately reducing their service life.

[0003] However, for the engine, the powertrain includes an air filter that supplies air to the engine. The air filter can filter impurities in the air, so the engine's air intake requirements can be met by the air filter.

[0004] However, the air intake of the continuously variable transmission does not have a filtering structure. Therefore, how to meet the air intake requirements of the continuously variable transmission to increase the service life of the continuously variable transmission is a technical problem that urgently needs to be solved in this field.

[0009] Further, the continuously variable transmission mechanism is at least partially located behind the seat assembly, and the transmission air inlet is at least partially located in front of the continuously variable transmission mechanism.

[0010] Furthermore, a longitudinal plane perpendicular to the width direction of the all-terrain vehicle and substantially bisecting the frame is defined, and the speed change air intake and the continuously variable transmission mechanism are located on the same side of the longitudinal plane.

[0011] Furthermore, an air supply port is provided on the continuously variable transmission mechanism, and the air supply port is located on a side of the continuously variable transmission mechanism away from the longitudinal plane.

[0012] Furthermore, the power assembly includes an air intake duct, both ends of which are connected to the continuously variable transmission mechanism and the transmission air intake port respectively, and the length of the air intake duct ranges from 600 mm to 800 mm.

[0013] Furthermore, one end of the air intake duct away from the continuously variable transmission mechanism is passed through the rear fender and communicated with the air intake port.

[0025] like Figure 1 and Figure 2 As shown, the present application provides an all-terrain vehicle 100 , which includes a frame 11 , a body panel 12 , a running system 13 , a suspension assembly 14 , a seat assembly 15 and a powertrain 16 .

[0026] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 In this application, the length direction of the all-terrain vehicle 100 refers to the front, rear, left, right, up, and down. Figure 1 The front-to-back direction in the all-terrain vehicle 100 is the width direction. Figure 1 The left and right directions in the text are as follows: the height direction of the all-terrain vehicle 100 refers to Figure 1 The up and down directions in .

[0027] Among them, the frame 11 serves as the basic framework of the all-terrain vehicle 100 and is used to support the body cover 12, the running system 13, the suspension assembly 14, the seat assembly 15 and the powertrain 16. The body cover 12 is connected to the frame 11, and the body cover 12 can protect the components inside the frame 11. The running system 13 is at least partially located below the frame 11, and the suspension assembly 14 connects the running system 13 to the frame 11 so that the running system 13 can be supported by the frame 11. The seat assembly 15 is used to provide support for the driver and / or passengers. The powertrain 16 is connected to the running system 13 in a transmission connection, so that the power of the powertrain 16 can be transmitted to the running system 13, so that the running system 13 can move.

[0028] Specifically, the travel system 13 includes front wheels 131 and rear wheels 132. The front wheels 131 are used for steering, while the rear wheels 132 are in transmission connection with the powertrain 16, enabling the rear wheels 132 to serve as the drive wheels of the ATV 100. It should be noted that in some embodiments, the front wheels 131 can also be in transmission connection with the powertrain 16, i.e., in this case, the ATV 100 is a four-wheel drive vehicle. Both the front wheels 131 and the rear wheels 132 are connected to the frame 11 via the suspension assembly 14.

[0029] Specifically, the powertrain 16 includes an engine 161 and a continuously variable transmission mechanism 162, which is in driving connection with the engine 161. The continuously variable transmission mechanism 162 can change the transmission ratio of the engine 161, thereby adjusting the output power of the engine 161. The continuously variable transmission mechanism 162 connects the engine 161 to the travel system 13. More specifically, the continuously variable transmission mechanism 162 connects the engine 161 to the rear wheels 132, thereby transmitting power from the engine 161 to the rear wheels 132.

[0030] Specifically, the seat assembly 15 includes a seat cushion 151 and a backrest 152 . The backrest 152 is at least partially located above the seat cushion 151 . Both the seat cushion 151 and the backrest 152 are supported by the vehicle frame 11 .

[0031] Specifically, the powertrain 16 also includes a transmission air inlet 163. The transmission air inlet 163 is supported by the vehicle frame 11. For example, the transmission air inlet 163 can be connected to the vehicle frame 11 via bolts. The transmission air inlet 163 is in communication with the continuously variable transmission mechanism 162, so that the transmission air inlet 163 can be used to supply air to the continuously variable transmission mechanism 162, thereby maintaining the continuously variable transmission mechanism 162 at an operating temperature and preventing the continuously variable transmission mechanism 162 from overheating and causing damage.

[0032] It should be noted that during the travel of the ATV 100, the rear wheel 132 may splash dust and other impurities to the outside of the ATV 100. To prevent the transmission air inlet 163 from inhaling the splashed impurities and damaging the continuously variable transmission mechanism 162, in this embodiment, the transmission air inlet 163 is located below the seat cushion 151.

[0033] More specifically, a reference plane 102 perpendicular to the height of the ATV 100 is defined. The projection of the transmission air inlet 163 along the height of the ATV 100 onto the reference plane 102 is referred to as the air inlet projection. The projection of the seat cushion along the height of the ATV 100 onto the reference plane 102 is referred to as the seat cushion projection. The seat cushion projection and the air inlet projection at least partially overlap. In other words, the air inlet projection can be located within the seat cushion projection, or the air inlet projection is at least partially located within the seat cushion projection.

[0034] Through the above-mentioned setting, the speed change air inlet 163 can be located inside the all-terrain vehicle 100, so that impurities splashed from the outside will not be transported to the continuously variable transmission mechanism 162 through the speed change air inlet 163, which is beneficial to improve the cleanliness of the air entering the continuously variable transmission mechanism 162 to meet the air intake requirements of the continuously variable transmission mechanism 162, and then avoid the continuously variable transmission mechanism 162 from being worn due to impurities, so as to improve the service life of the continuously variable transmission mechanism 162.

[0035] like Figure 2 and Figure 3 As shown, as an implementation, the body cover 12 includes a rear fender 121 , which is supported by the frame 11 and at least partially located in front of the rear wheel 132 , so that the rear fender 121 can block impurities such as mud and water splashed by the rear wheel 132 .

[0036] Specifically, the transmission air inlet 163 is located in front of the rear fender 121, so that the rear fender 121 can prevent mud, water and other impurities from splashing into the transmission air inlet 163, thereby preventing impurities from entering the continuously variable transmission mechanism 162 and causing damage to the continuously variable transmission mechanism 162, thereby improving the service life of the continuously variable transmission mechanism 162.

[0037] As an implementation, the continuously variable transmission mechanism 162 is at least partially located behind the seat assembly 15, and the speed-shifting air inlet 163 is at least partially located in front of the continuously variable transmission mechanism 162. This shortens the distance between the continuously variable transmission mechanism 162 and the speed-shifting air inlet 163, thereby facilitating a shorter duct between the continuously variable transmission mechanism 162 and the speed-shifting air inlet 163. Specifically, the powertrain 16 includes an intake duct 164, the ends of which respectively connect to the continuously variable transmission mechanism 162 and the speed-shifting air inlet 163. This arrangement shortens the length of the intake duct 164, thereby reducing the cost and weight of the intake duct 164 and achieving a lightweight powertrain 16.

[0038] In the present application, one end of the intake duct 164 away from the continuously variable transmission mechanism 162 passes through the rear fender 121 and is connected to the air intake port, so that the intake duct 164 does not need to bypass the rear fender 121, thereby further shortening the length of the intake duct 164.

[0039] In this embodiment, a longitudinal plane 101 is defined, perpendicular to the width of the ATV 100 and substantially bisecting the frame 11. The speed-shifting air inlet 163 and the continuously variable transmission mechanism 162 are located on the same side of the longitudinal plane 101. This arrangement allows the speed-shifting air inlet 163 and the continuously variable transmission mechanism 162 to be located on either the left or right side of the ATV 100. This eliminates the need for the air intake duct 164 to pass through the longitudinal plane 101. Specifically, the air intake duct 164 does not need to pass from one side of the ATV 100 to the other along its width. This shortens the length of the air intake duct 164 and prevents interference between the air intake duct 164 and other components of the ATV 100, thereby improving the operational stability of the air intake duct 164 and other components of the ATV 100.

[0040] Specifically, the continuously variable transmission mechanism 162 is provided with an air delivery port 1621, which is located on a side of the continuously variable transmission mechanism 162 away from the longitudinal plane 101. This arrangement allows the air delivery port 1621 to be closer to the speed change air inlet 163, thereby further shortening the length of the air inlet duct 164.

[0041] As an implementation, the length of the intake duct 164 ranges from 600 mm to 800 mm. Specifically, the length of the intake duct 164 ranges from 650 mm to 750 mm. More specifically, the length of the intake duct 164 is 700 mm. This arrangement avoids excessive length of the intake duct 164, which would otherwise lead to redundancy, thereby reducing the cost and quality of the intake duct 164. It also avoids the intake duct 164 being too short to accommodate the arrangement of the continuously variable transmission mechanism 162 and the transmission air inlet 163, thereby improving the operating stability of the continuously variable transmission mechanism 162.

[0042] It should be noted that the length range of the above-mentioned intake duct 164 is formed by the arrangement of the continuously variable transmission mechanism 162, the speed-changing air inlet 163, and the intake duct 164, that is, the arrangement of the continuously variable transmission mechanism 162, the speed-changing air inlet 163, and the intake duct 164 can shorten the length of the intake duct 164 to simplify the structure of the intake duct 164.

[0043] like Figure 2 and Figure 4 As shown, in order to further prevent external impurities from entering the transmission air intake 163, the body covering 12 of the present application includes a seat side panel 122, a seat front baffle 123 and a seat cover 124, and the seat side panel 122, the seat front baffle 123 and the seat cover 124 are all supported by the frame 11, that is, the seat side panel 122, the seat front baffle 123 and the seat cover 124 are all installed on the frame 11.

[0044] Specifically, the seat side panel 122 is located at a position away from the longitudinal plane 101 (refer to FIG. Figure 3 ) on one side, the seat front baffle 123 is located in front of the seat side panel 122, the seat cover 124 is located above the seat side panel 122 and is connected to the seat cushion 151, the rear fender 121 is located behind the seat side panel 122, and the seat side panel 122, the seat front baffle 123, the seat cover 124 and the rear fender 121 are surrounded to form an accommodating space 1201, and the speed change air intake 163 is located in the accommodating space 1201.

[0045] Through the above-mentioned setting, the speed transmission air inlet 163 can be located in a space surrounded by the vehicle body cover 12, so that external impurities cannot enter the speed transmission air inlet 163, thereby avoiding external impurities causing wear of the continuously variable transmission mechanism 162, thereby further improving the service life of the continuously variable transmission mechanism 162.

[0046] It should be noted that the seat side panels 122, the seat front panel 123, and the seat cover 124 can be snap-fitted or connected to each other, thereby making the seat side panels 122, the seat front panel 123, and the seat cover 124 more stable. Alternatively, the seat side panels 122, the seat front panel 123, and the seat cover 124 can fit together, that is, in this case, there is no connection between the seat side panels 122, the seat front panel 123, and the seat cover 124.

[0047] It should be noted that the storage space 1201 formed by the seat side panels 122, the seat front panel 123, the seat cover 124, and the rear fender 121 is not a sealed space. That is, the storage space 1201 is open to the outside world, allowing air from outside to enter the storage space 1201, thereby enabling the transmission air intake 163 to continuously draw air in. However, due to the obstruction of the seat side panels 122, the seat front panel 123, the seat cover 124, and the rear fender 121, foreign matter is unlikely to enter the storage space 1201, thereby maintaining a high degree of air cleanliness within the storage space 1201.

[0048] In this embodiment, the transmission air inlet 163 is provided with an air inlet opening 1631, which is disposed toward the seat side panel 122. Since impurities are minimized between the seat side panel 122 and the transmission air inlet 163, this arrangement further improves the cleanliness of the air entering the transmission air inlet 163, thereby facilitating reduced wear of the continuously variable transmission mechanism 162 and thereby increasing the service life of the continuously variable transmission mechanism 162.

[0049] It should be noted that the orientation of the air inlet opening 1631 of the present application can also be adjusted according to usage requirements, that is, the orientation of the air inlet opening 1631 can be in any direction, and this application does not impose any restrictions.

[0050] As an implementation method, the vehicle frame 11 further includes a seat frame 111 , which is located below the seat cushion 151 and connected to the seat cushion 151 , so that the seat frame 111 can serve as a support frame for the seat cushion 151 to improve the working stability of the seat cushion 151 .

[0051] Specifically, the speed change air inlet 163 is located below the seat frame 111 and connected to the seat frame 111, thereby facilitating improved stability of the speed change air inlet 163. The speed change air inlet 163 can be bolted to the seat frame 111, thereby further improving stability of the speed change air inlet 163.

[0052] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
