Description

Technical Field

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

[0002] An all-terrain vehicle is a multi-functional vehicle designed specifically for various complex terrains. It can travel freely on terrains that are difficult for ordinary vehicles to traverse, such as beaches, riverbeds, forest roads, streams, and deserts.

[0003] All-terrain vehicles (ATVs) typically include body panels, a running gear, a suspension system, a powertrain, a radiator, and fuel system. The powertrain is connected to the radiator so that the cooling system can dissipate heat from the powertrain. In existing technology, air exiting the radiator enters the ATV's interior, causing the overall vehicle temperature to become excessively high. Furthermore, the heat from the radiator-exiting air is transferred to the ATV's body, leading to excessively high perceived temperatures for the driver and passengers, thus reducing ride comfort. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with better riding comfort.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An all-terrain vehicle includes a frame, body panels, a running gear, a suspension system, and a cooling assembly; the body panels are supported by the frame; the running gear is at least partially located below the frame; the suspension system connects the running gear to the frame; a powertrain is supported by the frame and driven by the running gear; the cooling assembly includes a radiator for cooling the powertrain, the radiator being supported by the frame and at least partially located in front of the frame; the body panels include a deflector mounted on the radiator and / or the frame, the deflector being at least partially located behind the radiator, and the deflector being configured to direct airflow through the radiator to both sides of the all-terrain vehicle in the width direction and / or below the all-terrain vehicle.

[0007] Furthermore, a flow guide space and a flow guide gap communicating with the flow guide space are formed between the deflector and the radiator. The flow guide gap is located on both sides of the flow guide space along the width direction of the vehicle frame, and / or the flow guide gap is located below the flow guide space. The flow guide space is configured to deliver the air flowing through the radiator to the outside of the flow guide space through the flow guide gap.

[0008] Furthermore, the body panel includes a first front fender and a second front fender distributed along the width direction of the vehicle frame. Both the first front fender and the second front fender are provided with fender heat dissipation holes, which are configured to communicate with the flow guide gaps located on both sides of the flow guide space.

[0009] Furthermore, the mudguard cooling vents are set along the width of the frame, penetrating through the first and second front mudguards.

[0010] Furthermore, the body panel includes a first lamp cover and a second lamp cover distributed along the width direction of the frame. Both the first lamp cover and the second lamp cover have heat dissipation holes, which are configured to communicate with the airflow gaps located on both sides of the airflow space.

[0011] Furthermore, the heat dissipation holes of the cover include a first heat dissipation hole and a second heat dissipation hole. The first heat dissipation hole is disposed through the first lamp cover and the second lamp cover in a substantially longitudinal direction along the width of the frame. Both the first lamp cover and the second lamp cover extend away from the radiator to form a protrusion. The second heat dissipation hole is opened on the protrusion, and the opening of the second heat dissipation hole is at least partially oriented downward.

[0012] Furthermore, when viewed from the width direction of the frame, the heat dissipation holes of the shroud and the airflow gap at least partially overlap.

[0013] Furthermore, the air deflector is at least partially recessed away from the radiator to form a recessed portion, and the non-recessed portion of the air deflector is defined as a flat portion, with the flat portion surrounding the recessed portion.

[0014] Furthermore, the recessed portion includes a groove bottom that is further away from the radiator than the flat portion and a groove wall that is connected to the flat portion. The groove wall is basically sloping and has air-enhancing holes for increasing air intake.

[0015] Furthermore, the air deflector includes a top mounting portion, a side mounting portion, and a lower mounting portion. The top mounting portion is located above the flat portion, the side mounting portion is located on at least one side of the flat portion along the width direction of the vehicle frame, and the lower mounting portion is located below the flat portion. The top mounting portion extends at least partially toward the radiator and is fixedly connected to the radiator. The lower mounting portion and the side mounting portion are both fixedly connected to the vehicle frame.

[0016] The all-terrain vehicle of this application has a radiator that can carry away the heat generated by the powertrain. This heat is discharged to the outside of the all-terrain vehicle with the airflow, and the airflow is guided by a deflector. Therefore, this application can reduce the overall vehicle temperature and prevent the driver and passengers from feeling too hot, thereby improving the ride comfort of the all-terrain vehicle.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, this application provides an all-terrain vehicle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, a powertrain 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19, and an electrical assembly 22.

[0025] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.

[0026] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panel 12, running gear 13, suspension system 14, powertrain 15, transmission assembly 16, fuel system 17, seat assembly 19, and electrical assembly 22. The body panel 12 is at least partially located on and connected to the frame 11, protecting the internal components of the all-terrain vehicle 100. The running gear 13 is at least partially located below the frame 11, and the suspension system 14 connects the running gear 13 to the frame 11. The powertrain 15 is drive-connected to the running gear 13; specifically, the transmission assembly 16 drives the powertrain 15 to the running gear 13. The fuel system 17 includes a fuel tank 171 for powering the powertrain 15; specifically, the fuel tank 171 supplies fuel to the powertrain 15. The electrical component 22 is supported by the frame 11, and is also supported by the body panel 12 or the frame 11. The electrical component 22 is used to display the driving data of the all-terrain vehicle 100 and control the operation of the all-terrain vehicle. The seat assembly 19 is supported by the frame 11 and is used to support the driver and / or passengers.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, in one implementation, the all-terrain vehicle 100 includes a heat dissipation assembly 25, supported by a frame 11, for dissipating heat from the powertrain 15 and the like. The heat dissipation assembly 25 includes a radiator 252 for dissipating heat from the powertrain 15, supported by the frame 11 and at least partially located in front of the frame 11. A body panel 12 includes a deflector 121 mounted to the radiator 252 and / or the frame 11. The deflector 121 is at least partially located behind the radiator 252 and is configured to direct airflow through the radiator 252 to both sides of the all-terrain vehicle 100 in the width direction and / or below the all-terrain vehicle 100. The radiator 252 carries away heat generated by the powertrain 15, which is discharged to the outside of the all-terrain vehicle 100 with the airflow, and the deflector 121 guides this airflow. Therefore, this application can reduce the overall temperature of the all-terrain vehicle 100 and prevent the driver and passengers from feeling too hot.

[0028] It should be noted that the lower part of the all-terrain vehicle 100 is a frame structure formed by the vehicle frame 11. Gaps are formed between the frames of the frame structure, and the air delivered to the lower part of the all-terrain vehicle 100 can pass through these gaps and be discharged to the outside of the all-terrain vehicle 100.

[0029] As one implementation, a flow guide space 1211 and a flow guide gap 1212 communicating with the flow guide space 1211 are formed between the deflector 121 and the radiator 252. The flow guide gap 1212 is located on both sides of the flow guide space 1211 along the width direction of the frame 11, and / or the flow guide gap 1212 is located below the flow guide space 1211. The flow guide space 1211 is configured to transport air flowing through the radiator 252 to the outside of the flow guide space 1211 through the flow guide gap 1212. The air flowing through the radiator 252 is first transported into the flow guide space 1211, then through the flow guide gaps 1212 on both sides and / or below the flow guide space 1211, and finally transported to both sides of the all-terrain vehicle 100 along the width direction and / or below the all-terrain vehicle 100. Therefore, the radiator 252 removes the heat generated by the powertrain 15, which can be discharged to the outside of the all-terrain vehicle 100, reducing the overall temperature of the all-terrain vehicle 100 and lowering the perceived temperature for the driver and passengers.

[0030] In one implementation, the body panel 12 includes a first front fender 122 and a second front fender 123 distributed along the width direction of the frame 11. The first front fender 122 and the second front fender 123 protect the internal components of the all-terrain vehicle 100 located between the first front fender 122 and the second front fender 123, preventing these internal components from being soiled or rusted by mud splashes, and preventing damage to these internal components from flying stones impacting them. Both the first front fender 122 and the second front fender 123 are provided with fender heat dissipation holes 1201, which are configured to communicate with the guide gaps 1212 located on both sides of the guide space 1211. The air flowing through the radiator 252 is first delivered to the flow guide space 1211, then through the flow guide gaps 1212 on both sides of the flow guide space 1211, and then through the mudguard heat dissipation holes 1201 on both sides, and finally delivered to both sides of the all-terrain vehicle 100 along the width direction.

[0031] Specifically, the mudguard heat dissipation holes 1201 are basically arranged along the width direction of the frame 11, passing through the first front mudguard 122 and the second front mudguard 123, so that air can pass directly and quickly through the mudguard heat dissipation holes 1201, thereby dissipating heat to both sides of the all-terrain vehicle 100 along the width direction, thereby quickly reducing the overall temperature of the all-terrain vehicle 100, and quickly reducing the perceived temperature of the driver and passengers.

[0032] In one implementation, the body panel 12 includes a first lamp cover 124 and a second lamp cover 125 distributed along the width direction of the frame 11. The first lamp cover 124 and the second lamp cover 125 are used to install and protect the lamps therein. Both the first lamp cover 124 and the second lamp cover 125 have heat dissipation holes 1202, which are configured to communicate with the airflow gaps 1212 located on both sides of the airflow space 1211. Air flowing through the radiator 252 is first delivered into the airflow space 1211, then through the airflow gaps 1212 on both sides of the airflow space 1211, and then through the heat dissipation holes 1202 on the first lamp cover 124 and the second lamp cover 125 respectively, and finally delivered to the outside of the all-terrain vehicle 100.

[0033] The first lamp cover 124 is integrally formed or fixedly connected to the first front mudguard 122, and the first lamp cover 124 is located on the outer side of the all-terrain vehicle 100 in the width direction relative to the first front mudguard 122. The second lamp cover 125 is integrally formed or fixedly connected to the second front mudguard 123, and the second lamp cover 125 is located on the outer side of the all-terrain vehicle 100 in the width direction relative to the second front mudguard 123.

[0034] Specifically, the heat dissipation vents 1202 of the radiator cover include a first heat dissipation vent 1202a and a second heat dissipation vent 1202b. The first heat dissipation vent 1202a is disposed substantially along the width direction of the frame 11, penetrating through the first lamp cover 124 and the second lamp cover 125. Air flowing through the radiator 252 is first delivered to the airflow guiding space 1211, then through the airflow guiding gaps 1212 on both sides of the airflow guiding space 1211, then through the first heat dissipation vent 1202a, and finally delivered to both sides of the all-terrain vehicle 100 along the width direction.

[0035] It should be noted that the first heat dissipation hole 1202a and the mudguard heat dissipation hole 1201 can cooperate with each other, so that the air flowing through the radiator 252 can be discharged from the first heat dissipation hole 1202a and the mudguard heat dissipation hole 1201 at the same time, thereby improving the heat dissipation efficiency of the all-terrain vehicle 100, and facilitating the installation and cooperation of the first lamp cover 124 and the first front mudguard 122, as well as the installation and cooperation of the second lamp cover 125 and the second front mudguard 123.

[0036] Both the first lamp cover 124 and the second lamp cover 125 extend away from the radiator 252 to form a protrusion 1203. A second heat dissipation hole 1202b is formed on the protrusion 1203, and the opening of the second heat dissipation hole 1202b is at least partially oriented downwards. Air flowing through the radiator 252 is first delivered to the guide space 1211, then through the guide gaps 1212 on both sides of the guide space 1211, then through the second heat dissipation hole 1202b, and finally delivered to the bottom of the all-terrain vehicle 100.

[0037] In this application, the opening of the second heat dissipation vent 1202b is inclined towards the lower front of the all-terrain vehicle 100, so that the air passing through the second heat dissipation vent 1202b is finally delivered to the lower front of the all-terrain vehicle 100. It should be noted that the second heat dissipation vent 1202b can also be arranged substantially along the width direction of the frame 11, penetrating through the first lamp cover 124 and the second lamp cover 125. This application does not limit the arrangement of the second heat dissipation vent 1202b.

[0038] More specifically, when viewed from the width direction of the frame 11, the heat dissipation holes 1202 of the shield and the air guide gap 1212 at least partially overlap, so that the air flowing out from the air guide gap 1212 can flow directly out from the heat dissipation holes 1202 of the shield along the width direction of the frame 11, thereby rapidly reducing the overall temperature of the all-terrain vehicle 100 and rapidly reducing the perceived temperature of the driver and passengers.

[0039] like Figure 6 As shown, in one implementation, the guide plate 121 is at least partially recessed away from the heat sink 252 to form a recessed portion 1213. The non-recessed portion of the guide plate 121 is defined as a flat portion 1214, and the flat portion 1214 is arranged around the recessed portion 1213. If the volume of the flow space 1211 is small, the air pressure in the flow space 1211 will be high, making it difficult for air to pass through the heat sink 252 and enter the flow space 1211. This will result in a small amount of air passing through the heat sink 252, leading to poor heat dissipation of the heat sink 252. The recessed portion 1213 increases the volume of the flow space 1211 between the guide plate 121 and the heat sink 252, allowing air to pass smoothly through the heat sink 252 and enter the flow space 1211, thereby improving the heat dissipation effect of the heat sink 252.

[0040] Specifically, the recessed portion 1213 includes a bottom 1213a and a wall 1213b. The bottom 1213a is further away from the radiator 252 than the flat portion 1214, and the wall 1213b is in contact with the flat portion 1214. The wall 1213b is basically inclined, and air inlet holes 1213c are provided on the wall 1213b to increase the air intake. The inclined wall 1213b acts as a guide for air, directing the air between the radiator 252 and the recessed portion 1213 to the space between the radiator 252 and the flat portion 1214, and then flowing into the airflow gap 1212. The air inlet 1213c is designed to allow the two sides of the guide plate 121 to be connected, so as to avoid excessive air pressure in the guide space 1211. This allows air to pass smoothly through the radiator 252 into the guide space 1211, increasing the air intake of the radiator 252 and thus improving the heat dissipation effect of the radiator 252.

[0041] It should be noted that, since the direction of air flow along the tank wall 1213b is perpendicular to the direction of air flow from the guide space 1211 to the other side of the guide plate 121 through the air inlet 1213c, the air in the guide space 1211 will not flow to the other side of the guide plate 121 through the air inlet 1213c.

[0042] In one implementation, the air deflector 121 includes a top mounting portion 1215, a side mounting portion 1216, and a lower mounting portion 1217. The top mounting portion 1215 is located above the flattened portion 1214, the side mounting portions 1216 are located on at least one side of the flattened portion 1214 along the width direction of the frame 11, and multiple side mounting portions 1216 can be provided on one side of the air deflector 121. The lower mounting portion 1217 is located below the flattened portion 1214. The top mounting portion 1215 extends at least partially toward the radiator 252, so that the top of the airflow space 1211 is closed by the top mounting portion 1215, thereby preventing air from flowing out from the top of the airflow space 1211. The top mounting portion 1215 is fixedly connected to the radiator 252, and the fixed connection between the top mounting portion 1215 and the radiator 252 can be a bolt connection or the like. The lower mounting part 1217 and the side mounting part 1216 are both fixedly connected to the frame 11. The fixed connection between the lower mounting part 1217 and the side mounting part 1216 and the frame 11 can be by bolt connection or the like.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
