Description

Technical Field

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

[0002] Existing transmission cooling systems utilize engine oil flowing from the transmission housing's outlet into an air-cooled oil cooler for cooling. The air-cooled oil cooler relies on the rapid airflow during vehicle operation to dissipate heat. The cooled transmission oil then flows out of the air-cooled oil cooler and re-enters the transmission housing through the inlet. However, transmissions generate significant heat, resulting in high temperatures, and existing cooling systems are ineffective at cooling them. Consequently, the internal temperature of the all-terrain vehicle becomes excessively high, leading to slow heat dissipation and impacting the vehicle's cooling performance and lifespan. Summary of the Invention

[0003] To address the issue of poor transmission heat dissipation, this invention provides an all-terrain vehicle, comprising: a frame; a body panel, at least partially disposed on the frame and including an instrument panel cover; a running gear, including a first running wheel and a second running wheel; a suspension assembly, including a front suspension and a rear suspension, the first running wheel being connected to the frame via the front suspension, and the second running wheel being connected to the frame via the rear suspension; a power system, including an engine for driving the running gear; a transmission assembly, disposed between the power system and the running gear and for transmitting power from the power system to the running gear; and an intake system, at least partially connected to the power system. The intake system further comprises: an air intake, at least partially disposed on the instrument panel cover; and an intake pipe connected to the transmission assembly.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the all-terrain vehicle 100 includes a frame 12, a fuel system 13, a steering assembly 16, an electrical system 17, an exhaust system 18, a control assembly 22, a body panel 23, a mounting bracket assembly 24, an intake system 25, a running gear 26, a suspension assembly 27, and a seat assembly 28. The frame 12 supports the steering assembly 16, the exhaust system 18, and the body panel 23. The mounting bracket assembly 24 is mounted on the frame 12. The steering assembly 16 controls the rotation of the running gear 26. The exhaust system 18 discharges gases generated during the operation of the all-terrain vehicle 100 to the external environment. The control assembly 22 is mounted on the frame 12 and connected to the body panel 23. The suspension assembly 27 connects the running gear 26 to the frame 12. To clearly illustrate the technical solution of the present invention, the following are also defined: Figure 1 The front, back, left, right, top, and bottom sides are shown.

[0030] like Figure 2As shown, the running gear 26 includes a first running wheel 261 and a second running wheel 262. Both the first running wheel 261 and / or the second running wheel 262 can serve as drive wheels for the all-terrain vehicle 100, and the first running wheel 261 is connected to the steering assembly 16 and can be rotated. The suspension assembly 27 includes a front suspension 271 and a rear suspension 272 (see...). Figure 1 The first traveling wheel 261 is connected to the frame 12 via the front suspension 271, and the second traveling wheel 262 is connected to the frame 12 via the rear suspension 272.

[0031] like Figure 3 As shown, the all-terrain vehicle 100 also includes a power system 11 and a transmission assembly 14. The power system 11 is mounted on the frame 12 and provides power to the all-terrain vehicle 100. The power system 11 includes an engine 111, which is connected to the transmission assembly 14. The transmission assembly 14 can change the driving force and travel speed of the all-terrain vehicle 100. The engine 111 includes at least one cylinder 1111 and a cylinder head 1112 located at one end of the cylinder 1111. The cylinder 1111 contains a combustion chamber and a piston assembly, and the combustion chamber is connected to the intake system 25. The engine 111 is mounted on the frame 12. In this embodiment, the transmission assembly 14 is a CVT transmission. It is understood that the transmission assembly 14 can also be other transmissions such as an AT automatic transmission, a DCT dual-clutch transmission, etc.

[0032] like Figure 4 As shown, the frame 12 is a metal frame, including a frame body 121 and a front support frame 122. The frame body 121 includes a first main beam 1211, a second main beam 1212, a third main beam 1213, a fourth main beam 1214, a fifth main beam 1215, a sixth main beam 1216, a seventh main beam 1217, an eighth main beam 1218, and a ninth main beam 1219. The frame body 121 can be manufactured by welding. In the front-rear direction, the front support frame 122 is located on the front side of the frame body 121. The front support frame 122 serves as an extension of the frame 12, which can extend the overall length of the frame 12, allowing the frame 12 to be equipped with more devices.

[0033] like Figure 5As shown, the exhaust system 18 includes an exhaust pipe 181 and a muffler 182. The exhaust system 18 is used to discharge the gas output by the power system 11. The gas enters the muffler 182 through the exhaust pipe 181 and is discharged into the outside air through the muffler 182. The exhaust pipe 181 and the muffler 182 extend substantially along the longitudinal direction of the all-terrain vehicle 100. The muffler 182 is located at the rear of the all-terrain vehicle 100 and is connected to the engine 111 through the exhaust pipe 181. A heat shield 183 and an exhaust pipe 184 are provided on the muffler 182. The gas enters the interior of the muffler 182 through the exhaust pipe 181, the muffler 182 processes the noise of the gas, and finally the gas is discharged into the outside air through the exhaust pipe 184. As one implementation, the exhaust pipe 184 has a curved structure and is located on the outer peripheral wall of the muffler 182, and is connected to the muffler 182. The exhaust pipe 184 is positioned on the lower side of the muffler 182. Compared to an arrangement where the exhaust pipe 184 is connected to the tail end of the muffler 182, this arrangement increases the longitudinal length of the exhaust pipe 184, thereby increasing the volume of the muffler 182. The connection point between the exhaust pipe 184 and the muffler 182 is the first connection point. The distance h between the first connection point and the tail end of the muffler 182 is greater than or equal to 0.1 and less than or equal to 0.2. This arrangement allows for the reception of gas after sufficient silencing by the muffler 182, and also provides space for the installation of other components of the all-terrain vehicle 100, while reducing the temperature impact of the exhaust gas on other components of the all-terrain vehicle 100.

[0034] like Figure 6As shown, in one implementation, a heat shield 183 is disposed at the end of the muffler 182 away from the exhaust pipe 181. The heat shield 183 includes a decorative layer 1831 and a heat insulation layer 1832. The decorative layer 1831 is in contact with the outside air, and the heat insulation layer 1832 is disposed between the decorative layer 1831 and the muffler 182, effectively insulating against heat conducted by the muffler 182. Understandably, to minimize heat transfer from the muffler 182, the thickness of the heat insulation layer 1832 is greater than the thickness of the decorative layer 1831 along the longitudinal direction of the all-terrain vehicle 100. Specifically, the heat insulation layer 1832 can be made of composite materials, which offer better heat insulation compared to traditional metal materials. Along the longitudinal direction of the all-terrain vehicle 100, the ratio of the thickness of the heat insulation layer 1832 to the thickness of the decorative layer 1831 is greater than or equal to 2. This arrangement means that the thickness of the heat insulation layer 1832 is at least twice the thickness of the decorative layer 1831, which ensures a certain heat insulation effect while reducing the difficulty in material manufacturing and assembly. Both the muffler 182 and the heat shield 183 have circular cross-sections. The diameter of the heat insulation layer 1832 is larger than the diameter of the tail end of the muffler 182, and the diameter of the decorative layer 1831 is larger than the diameter of the heat insulation layer 1832. Understandably, the heat shield 183 can have other shapes, but the inner diameter of the heat insulation layer 1832 is larger than the diameter of the muffler 182, and the inner diameter of the decorative layer 1831 is larger than the inner diameter of the heat insulation layer 1832.

[0035] like Figure 7 As shown, the air intake system 25 is used to supply clean, dry, sufficient, and stable air to the engine 111. The air intake system 25 includes an air intake 251 and an air intake pipe 252. The body panel 23 includes an instrument panel 23b. The air intake 251 is at least partially disposed on the instrument panel 23b. In the driving direction of the all-terrain vehicle 100, the instrument panel 23b has a windward surface 23ba. The all-terrain vehicle 100 includes a first projection surface 304 perpendicular to the vertical direction of the all-terrain vehicle 100 and a second projection surface 305 perpendicular to the horizontal direction of the all-terrain vehicle 100. The first projection surface 304 and the second projection surface 305 are arranged perpendicular to each other. The windward surface 23ba is substantially perpendicular to the second projection surface 305. Along the horizontal direction of the all-terrain vehicle 100, the projection of the windward surface 23ba onto the second projection surface 305 is a first projection line, and the projection of the first projection surface 304 onto the second projection surface 305 is a second projection line. In this embodiment, the included angle M between the first projection line and the second projection line is greater than or equal to 45° and less than or equal to 90°. This arrangement reduces the length of the instrument cover 23b in the longitudinal direction of the all-terrain vehicle 100, making the structure of the all-terrain vehicle 100 more compact, improving its space utilization, and enhancing its maneuverability.

[0036] Specifically, the included angle M between the first projection line and the second projection line is greater than or equal to 50° and less than or equal to 80°. Through this setting, the length of the instrument cover 23b in the longitudinal direction of the all-terrain vehicle 100 can be reduced, thereby decreasing the longitudinal length of the instrument cover 23b, making the structure of the all-terrain vehicle 100 more compact, improving the space utilization of the all-terrain vehicle 100, and enhancing the driving maneuverability of the all-terrain vehicle 100.

[0037] The instrument panel cover 23b has at least one air inlet 251 on its windward side 23ba. In this embodiment, the instrument panel cover 23b divides the windward side 23ba into multiple air inlets 251 by providing multiple baffles 23bb. Ambient air enters the interior of the instrument panel cover 23b through the air inlets 251, thereby causing the ambient air to flow to the air intake pipe 252. The air intake pipe 252 is connected to the transmission assembly 14, allowing ambient air to enter the transmission assembly 14, thereby reducing the internal temperature of the transmission assembly 14. Specifically, the baffles 23bb are substantially perpendicular to the second projection plane 305. Along the left-right direction of the all-terrain vehicle 100, the projection of the baffles onto the second projection plane 305 is a third projection line. The angle N between the second projection line and the third projection line is greater than or equal to 9° and less than or equal to 11°. With the above settings, the amount of air entering the instrument cover 23b can be sufficient, and water and other liquids can be prevented from flowing to the rear of the instrument cover 23b, thus preventing water and other liquids from entering the interior of the instrument cover 23b, thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100.

[0038] In this embodiment, the angle N between the second projection line and the third projection line is 10°. At this time, the amount of air entering the instrument cover 23b can meet the requirements, while preventing liquids such as water from flowing to the rear of the instrument cover 23b and avoiding the entry of liquids such as water into the interior of the instrument cover 23b, thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100.

[0039] As one implementation, the windward surface 23ba includes a left windward surface and a right windward surface. The left windward surface is provided with at least one air inlet 251 and at least one baffle 23bb, and the right windward surface is provided with at least one air inlet 251 and at least one baffle 23bb. Specifically, the number of air inlets 251 provided on the left and right windward surfaces can be the same, or the number of air inlets 251 provided on the left and right windward surfaces can be different, and can be adjusted according to requirements. The number of baffles 23bb provided on the left and right windward surfaces can be the same, or the number of air inlets 251 provided on the left and right windward surfaces can be different, and can be adjusted according to requirements. Through the above configuration, the amount of air entering the instrument cover 23b can meet the requirements, while preventing liquids such as water from flowing to the rear of the instrument cover 23b and avoiding the entry of liquids such as water into the interior of the instrument cover 23b, thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100.

[0040] like Figure 8 As shown, in one implementation, the intake pipe 252 includes a first intake pipe 2521, a connector 2522, and a second intake pipe 2523. The connector 2522 includes a first connecting portion 2522a and a second connecting portion 2522b. The first connecting portion 2522a is disposed between the first intake pipe 2521 and the second intake pipe 2523, and is used to connect the first intake pipe 2521 and the second intake pipe 2523. One end of the first intake pipe 2521 is connected to the instrument cover 23b, and the other end of the first intake pipe 2521 is connected to the first connecting portion 2522a. One end of the second intake pipe 2523 is connected to the first connecting part 2522a. The second connecting part 2522b is disposed between the second intake pipe 2523 and the transmission assembly 14. The other end of the second intake pipe 2523 is connected to the second connecting part 2522b. The end of the second connecting part 2522b away from the second intake pipe 2523 is connected to the transmission assembly 14. Both the first connecting part 2522a and the second connecting part 2522b are hollow annular structures. Ambient air enters the instrument cover 23b from the air inlet 251, is introduced into the second intake pipe 2523 through the first intake pipe 2521, and is then introduced into the transmission assembly 14 from the second intake pipe 2523. In one implementation, the first air intake pipe 2521 is connected to the ninth main beam 1219 by bolts. The second air intake pipe 2523 includes a first channel 2523a and a second channel 2523b. One end of the first channel 2523a is connected to the first connecting portion 2522a, and the other end of the first channel 2523a is connected to the second connecting portion 2522b. The second channel 2523b is arranged around the ninth main beam 1219. One end of the second channel 2523b enters the first connecting portion 2522a from one side, and the end of the second channel 2523b away from the first connecting portion 2522a is connected to the first channel 2523a. The inner diameter of the second channel 2523b is smaller than the inner diameter of the first channel 2523a. In this embodiment, the connector 2522 can be made of an elastic material. Specifically, the connector 2522 can be made of rubber. Utilizing the elasticity of the rubber, it can absorb the force of the intake pipe 252 swinging during the movement of the all-terrain vehicle 100, thereby reducing the vibration of the intake pipe 252 and thus reducing frictional loss. A clamp is also provided on the outside of the connector 2522 for further securing the connection. The instrument cover 23b can introduce ambient air into the vehicle body, which is then introduced to the transmission assembly 14 through the intake pipe 252, effectively reducing the internal temperature of the transmission assembly 14. The intake pipe 252 utilizes a branched intake pipe design, increasing the air intake area and effectively improving the air intake volume, solving the problem of insufficient air intake, greatly improving air intake efficiency, achieving better heat dissipation, and fully utilizing the internal space of the all-terrain vehicle 100, thus improving space utilization.

[0041] like Figures 9 to 11 As shown, the all-terrain vehicle 100 also includes a cooling system 19, which can promptly transfer heat from inside the all-terrain vehicle 100 to the ambient air, allowing the all-terrain vehicle 100 to operate at the most suitable temperature. In one implementation, the cooling system 19 includes a radiator 191, a water tank 192, a fan vent 193, and a water pipe clamp 194. The radiator 191 has an air intake surface and an air exhaust surface corresponding to the air intake and exhaust directions, respectively. A deflector 195 is provided on the radiator 191 to prevent hot air exhausted from the exhaust surface from being drawn back to the intake surface. A deflector 195 is positioned between the radiator 191 and the body panel 23. The deflector 195 is bolted to the radiator 191 and surrounds the air intake surface, creating an airflow cavity between the radiator 191 and the body panel 23. Ambient air drawn in from the body panel 23 flows primarily along this airflow cavity towards the air intake surface. This configuration effectively improves the air intake efficiency of the deflector 195, effectively blocks the recirculation of hot air, significantly enhances the heat dissipation effect of the radiator 191, and reduces the temperature inside the all-terrain vehicle 100 and around the radiator 191.

[0042] like Figure 11 As shown, an adapter bracket 196 is provided on the side of the radiator 191, which is used to install the water tank 192. The side of the radiator 191 refers to the surface perpendicular to the air inlet and exhaust surfaces and located on both sides of the radiator 191. As one implementation, the water tank 192 is connected to the adapter bracket 196 by bolts, making the water tank 192 easy to disassemble, install, and replace.

[0043] like Figure 11 and Figure 12 As shown, the adapter bracket 196 includes a base plate 1961 and a side plate 1962, which are fixedly connected. The base plate 1961 is perpendicular to the exhaust surface and is bolted to the water tank 192. The side plate 1962 extends along the exhaust surface of the radiator 191 and surrounds one side of the radiator 191, with one end of the side plate 1962 folded to form a flange parallel to the base plate 1961. The adapter bracket 196 is fixed to the radiator 191 by the flange. Specifically, the side plate 1962 extends along the exhaust surface of the radiator 191 and surrounds one side of the radiator 191.

[0044] As one implementation method, the adapter bracket 196 is fixed to one side of the radiator 191 by welding, and the base plate 1961 and the side plate 1962 can be integrally formed. Compared with the secondary water tank installation in the prior art, in this embodiment, the water tank 192 can be integrated and installed on the radiator 191 through the adapter bracket 196. The adapter bracket 196 solves the installation problem of the water tank 192, which helps to save the installation space of the water tank 192 and reduce the assembly labor and material costs.

[0045] like Figure 13 As shown, the fan vent 193 is used to expel hot air from inside the radiator 191 and help the radiator 191 dissipate heat. The fan vent 193 is located behind the radiator 191 and is connected to the front support frame 122, enabling the exhaust air path to be connected to the front support frame 122, from which the hot air is directed to the outside of the all-terrain vehicle 100. The exhaust air path refers to the trajectory of the hot air expelled from the fan vent 193 as it travels towards the front support frame 122. Because the diameter of the fan vent 193 is relatively small, it is prone to water ingress or blockage by sediment. Therefore, the installation position and exhaust direction of the fan vent 193 are particularly important.

[0046] As one implementation, the fan vent 193 is mounted on the front support frame 122 via a connector 1931. The connector 1931 is a hollow structure; one end of the connector 1931 connects to the front support frame 122, and the other end of the connector 1931 is press-fitted with the fan vent 193. This allows hot air from inside the radiator 191 to be guided to the front support frame 122, and then exhausted to the external environment through vents and / or weight-reduction holes arranged on the front support frame 122. There is no need to consider the exhaust air path of the fan vent 193. This configuration solves the installation problem of the fan vent 193. By more rationally arranging the fan vent 193, installation costs are reduced, and it effectively prevents mud, water, etc., from entering the fan vent 193 and affecting the performance of the radiator 191.

[0047] like Figure 14As shown, the water pipe of the radiator 191 is fixed to the frame 12 by the water pipe clamp 194. The water pipe clamp 194 is provided with an installation space for fixing the water pipe. The cross-section of the installation space is basically circular, and the diameter of the cross-section of the installation space is smaller than the diameter of the water pipe, so that the water pipe clamp 194 and the water pipe are interference fit, thereby realizing the fixation between the water pipe clamp 194 and the water pipe. A limiting post 1941 is provided on the outer wall of the water pipe clamp 194. At least one pair of limiting plates 1942 are symmetrically arranged on the limiting post 1941. The limiting post 1941 is connected to the frame 12, allowing the water pipe clamp 194 to be installed on the frame 12. During installation, the limiting plates 1942 act as guides, facilitating the installation of the water pipe clamp 194 on the frame 12. The water pipe clamp 194 is engaged with the frame 12 by the limiting plates 1942, thus preventing the limiting post 1941 from moving and preventing the water pipe clamp 194 from falling off, providing a good fixing effect. The angle between the outer plane of the limiting post 1941 and the limiting plate 1942 is greater than 0° and less than or equal to 90°. The symmetrical arrangement of multiple pairs of limiting plates 1942 on the limiting post 1941 provides better anti-reverse effect, making the connection between the water pipe clamp 194 and the frame 12 more stable and reliable. The pipe clamp 194 also has an opening connecting to the installation space. Folded flanges 1943 are provided on both sides of the opening. These flanges 1943 facilitate manual installation by widening the opening of the pipe clamp 194, making it easier for assembly workers to connect the water pipe to the clamp. Alternatively, a sleeve can be installed on the water pipe corresponding to the installation position of the pipe clamp 194. The outer diameter of the sleeve must be larger than the diameter of the installation space. The sleeve and the pipe clamp 194 are fixed together, reducing wear on the water pipe and serving as an indicator of the installation position. During installation, simply confirming that the sleeve corresponds to the pipe clamp 194 allows for verification of correct pipe installation. The sleeve can be made of polyethylene and installed on the water pipe using a heat-shrink process. The pipe clamp 194 can be made of plastic. Using the pipe clamp 194 to fix the water pipe effectively reduces manual assembly costs and simplifies assembly. Furthermore, the use of plastic for the pipe clamp 194 helps control costs.

[0048] 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.
