Description

Technical Field

[0001] This invention relates to the field of outdoor cycling equipment, and more particularly to an all-terrain vehicle. Background Technology

[0002] All-terrain vehicles (ATVs) are a common type of outdoor riding vehicle. The structure of current ATVs is roughly as shown in patent publication document CN220395815U. Since ATVs often need to travel on rough roads, if the driver adopts an incorrect riding posture or the speed is too high (especially when turning), the ATV has a certain probability of tipping over. Because ATVs require the driver to ride in a straddle position, and ATVs do not have A-pillars, B-pillars, and C-pillars like traditional cars, and the weight of ATVs is greater than that of traditional motorcycles, if the rider's legs are trapped under the vehicle after an ATV tip over, not only is the rider easily injured, but it is also very difficult to get out of the predicament on their own. To prevent all-terrain vehicles from tipping over during riding, patent publication CN109703636B discloses a method for real-time calibration of the vehicle's posture using a hydraulic system based on the vehicle's operating status. However, this real-time calibration method has a problem: it only adjusts the vehicle's posture without taking corresponding speed reduction measures. On winding roads, adjusting the posture without reducing speed still carries a high probability of tipping over. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes an all-terrain vehicle that uses a pressure sensor in combination with an electric fuel pump to achieve rapid deceleration when the riding posture is incorrect, thereby reducing the probability of the vehicle overturning.

[0004] The technical solution adopted in this invention is as follows:

[0005] An all-terrain vehicle includes a frame, an engine, a fuel tank, and an electric fuel pump. Wheels are mounted on the frame, and each wheel has an agricultural tire. The engine, fuel tank, and electric fuel pump are all mounted on the frame. The engine is connected to some of the wheels via a drive shaft. The electric fuel pump is connected to the engine and fuel tank via pipelines. The vehicle also includes foot pedals. A saddle is mounted on the frame, and a first pressure sensor is mounted on the saddle. A positioning rod is mounted on the frame. Positioning holes are formed on the foot pedals, and these holes are fitted onto the positioning rod. A second pressure sensor is positioned between the frame and the foot pedals. There are two foot pedals, located on opposite sides of the frame. A second pressure sensor is positioned between each foot pedal and the frame. A steering rod is rotatably mounted on the frame, and an coded sensor is positioned between the frame and the steering rod.

[0006] In this type of all-terrain vehicle, the wheels use agricultural tires used on tractors. These tires have high friction with the ground and strong grip, which ensures that the tires can travel on various rough roads. At the same time, when the engine stops, the vehicle speed will drop quickly due to the strong grip of the tires. Therefore, the all-terrain vehicle can be regarded as a tractor with reduced horsepower, and its off-road performance is excellent.

[0007] In this type of all-terrain vehicle, the electric fuel pump pumps fuel from the fuel tank to the engine's carburetor, thereby driving the engine. The amount of fuel pumped to the engine can be controlled by the electric fuel pump, and the engine stops running when the electric fuel pump stops pumping fuel.

[0008] The specific operating process of this all-terrain vehicle is as follows: When the rider adopts a correct straddle posture, their buttocks are on the saddle, at which point the first pressure sensor can detect the pressure value. The rider's two feet are on the two foot pedals, so the two second pressure sensors can also detect the pressure value. Only when both the first and second pressure sensors detect the pressure value will the onboard computer control the fuel pump to start. If the onboard computer fails to detect the pressure value of either pressure sensor, the fuel pump immediately stops, preventing fuel from being pumped to the engine, causing the engine to quickly shut off, thus achieving rapid deceleration until the vehicle stops. Therefore, this type of vehicle uses a combination of pressure sensors to achieve linkage between the pressure sensors and the fuel pump, thereby enabling rapid deceleration when the riding posture is incorrect, reducing the probability of the vehicle tipping over. If a safe and correct riding posture is not adopted from the beginning, the vehicle will not even be able to start.

[0009] Furthermore, this type of vehicle further incorporates an coded sensor (including but not limited to a photoelectric coded sensor) between the chassis and the steering rod. The function of the coded sensor is to detect the amount of rotation of the steering rod. Because the steering rod needs to rotate relative to the chassis when the vehicle needs to turn, this vehicle further incorporates a coded sensor to monitor the amount of rotation of the steering rod. The amount of rotation of the steering rod represents the amount of steering of the vehicle's front wheels. The onboard computer further uses the amount of rotation of the steering rod detected by the magnetic coded sensor to adjust the oil pump speed. Assuming the oil pumping speed is A at a certain moment, if the magnetic encoder measures a rotation of 5 degrees, the onboard computer immediately reduces the oil pumping speed to 0.8A. If the rotation is 10 degrees, it immediately reduces to 0.5A. If the measured rotation reaches 20 degrees, it immediately reduces to the minimum oil pumping speed B (B is a specific set value, set by the manufacturer for the onboard computer at the factory; if 0.8A is already less than the value of B, then the value of B is maintained). This achieves the setting of the minimum speed for cornering and steering. This system, using coded sensors, enables automatic speed reduction during steering and sets a minimum pump oil volume. It achieves automatic deceleration during steering and reversing, and ensures that the vehicle will not stop automatically, further improving operational reliability and reducing the probability of overturning.

[0010] Optionally, it may also include an on-board gyroscope, which is mounted on the vehicle frame.

[0011] The vehicle has four wheels: two front wheels and two rear wheels. The engine is connected to the two rear wheels via a linkage. The entire all-terrain vehicle is rear-wheel drive. The onboard gyroscope is located between the two front wheels. The function of the onboard gyroscope is to detect the tilt of the entire frame. By monitoring the tilt of the vehicle, the ruggedness and steepness of the road can be determined. For excessively rugged and steep roads, in order to prevent dangerous accidents caused by riding on such roads, when the onboard gyroscope senses that the vertical tilt of the front of the vehicle during travel reaches a certain value (the horizontal tilt can cause the steering lever to rotate, which is detected by the coded sensor), the pump oil volume is directly reduced to the minimum value B, effectively stopping the vehicle directly and preventing the engine from shutting down and causing a large rollback.

[0012] Optionally, the frame is provided with a clamping platform, and a storage battery is disposed within the clamping platform.

[0013] The purpose of the clamp is to install the storage battery.

[0014] Optionally, a support plate is provided on the frame, and the second pressure detection sensor is disposed on the support plate.

[0015] Optionally, it also includes a rear seat frame, which is mounted on the vehicle frame. The vehicle frame is equipped with armrests, and there is an armrest on each side of the rear seat frame. A third pressure sensor is mounted on the rear seat frame, and a card slot is mounted on the rear seat frame.

[0016] The rear seat frame serves as a passenger compartment. The third pressure sensor detects whether a passenger is seated. If a passenger is seated, the onboard computer directly limits the vehicle's speed based on the maximum fuel pumping speed, thus controlling the vehicle's speed. The handrails provide a place for passengers to put their hands on the seatbelts, while the card slots allow passengers to insert seatbelts when necessary.

[0017] Optionally, it also includes a tow hook, a wide-angle camera, and a display screen, all of which are mounted on the vehicle frame. The wide-angle camera is electrically connected to the display screen via an onboard computer.

[0018] The tow hook and wide-angle camera are located at the rear of the vehicle frame, while the display screen is located at the front of the vehicle frame. The display screen is also electrically connected to the onboard computer and displays information from the onboard computer. When this type of vehicle is used as a tow truck, the wide-angle camera can be turned on to acquire image information for the tow hook and the towed vehicle.

[0019] Optionally, it also includes a grille-shaped radiator and an air intake pipe. The grille-shaped radiator is mounted on the vehicle frame and has heat dissipation fins arranged on it. One port of the air intake pipe is connected to the engine, and the other port of the radiator is located on one side of the heat dissipation fins. A fan is mounted on the vehicle frame and is located on the same side of the heat dissipation fins as the air intake pipe.

[0020] The purpose of a grille-shaped radiator is to cool the engine coolant.

[0021] Because this type of vehicle often needs to drive on muddy roads, which splashes mud and dust, this mud and dust can damage the engine filter after entering the intake pipe. Therefore, in this solution, one end of the intake pipe is detachably connected to the engine's air intake via a clamp, while the other end of the intake pipe is located near the cooling fins of the grille-shaped radiator. When the vehicle is in motion, the airflow passes through the fins from the front and then flows into the intake pipe. In this way, even if the vehicle encounters mud and dust during driving, the arranged cooling fins act as a filter, reducing the probability of dust and mud entering the intake pipe.

[0022] Meanwhile, in this type of vehicle, the intake pipe and fan are located on the same side of the heat dissipation fins. When the fan is running, it draws air from one side of the heat dissipation fins to the side of the intake pipe. This not only increases the airflow speed and speeds up the heat dissipation efficiency of the heat dissipation fins, but also increases the air intake volume of the intake pipe, thereby achieving rapid air intake and ensuring that the air intake pipe will not have difficulty entering due to the obstruction of the heat dissipation fins, ensuring that the airflow rushes into the intake pipe at a high speed.

[0023] Optionally, the intake pipe clamping sleeve is fitted with several longitudinal stops and several transverse stops. The longitudinal stops are perpendicular to the transverse stops, and the longitudinal stops are parallel and do not contact each other. The transverse stops are parallel and do not contact each other. The longitudinal stops and transverse stops do not contact each other. The intake pipe is cylindrical, and several semi-circular plates are provided on the inner wall of the intake pipe. Adjacent semi-circular plates do not contact each other. Each semi-circular plate forms a clamping groove with the inner wall of the intake pipe, and the opening of each clamping groove faces the clamping sleeve.

[0024] The longitudinal and transverse baffles on the clamping sleeve form two layers of filters without mesh openings. These two layers of filters serve two purposes: firstly, they prevent small animals from crawling into the air intake pipe; secondly, because they lack mesh openings, they have relatively little obstruction to airflow, ensuring efficient air intake. Additionally, due to electrostatic effects, the longitudinal and transverse baffles can adsorb dust and short fibers to a certain extent. When cleaning is required, simply remove the clamping sleeve and rinse it with a high-pressure water gun.

[0025] Meanwhile, in this design, each semicircular plate forms a groove between itself and the inner wall of the intake pipe, with the opening of each groove facing the clamping sleeve. This way, the airflow entering the intake pipe is blocked by the semicircular plates, which can further adsorb and purify dust. If some moisture in the airflow is trapped, it will also be trapped by the grooves, forming water that is collected within the grooves. Dust is further adsorbed and trapped by the water in the grooves, thus achieving efficient air purification and maximizing the service life of the engine air filter.

[0026] When cleaning is needed, simply disassemble the air intake pipe, rinse it with a high-pressure water gun, and then dry it in the sun.

[0027] Optionally, it also includes a handlebar and a handlebar lever. The handlebar is made of metal and is fixedly fitted to one end of the steering lever. The handlebar is equipped with a brake lever, a manual throttle, and a parking handle. The handlebar lever has a cavity containing a heating element filled with heat-conducting oil. The end of the handlebar has a slot. Both the handlebar lever and the handlebar are fitted with a bonding plate. The bonding plate of the handlebar lever is welded and fixed to the bonding plate of the handlebar. A rigid heat-insulating sleeve is provided between the handlebar and the handlebar lever.

[0028] In traditional bicycle handlebars, the handlebar and handlebar stem are integrated, either from a single high-strength, high-bending piece or directly cast in one piece. In this application, the handlebar stem and handlebar are welded together, creating a cutable and replaceable liquid-heated handlebar stem. By grinding away the weld points between the two bonding plates, the handlebar stem can be disassembled, replaced with a new one, and then re-welded in place. Because it receives the heat-conducting oil, the temperature of the entire handlebar stem is uniform. Furthermore, compared to the traditional method of directly installing resistance wires on the handlebar stem, using liquid heat transfer avoids overheating at certain points, preventing burns to the user. It also prevents the high temperature of the resistance wire from igniting flammable materials.

[0029] Specifically, in this type of handlebar, the maximum heating temperature of the heat transfer medium oil can be set to no more than 37 degrees Celsius, thus providing the user with the best grip.

[0030] Specifically, the rigid heat insulation sleeve can be made of ABS engineering plastic. The function of the heat insulation sleeve is to reduce heat convection between the handlebar and the handlebar.

[0031] Optionally, the handle includes a rod body, a sealing end, and a heat-conducting metal mesh sleeve. The cavity is disposed within the rod body. The sealing end and the rod body are threaded together. A sealing gasket is disposed between the rod body and the sealing end. The rod body is made of cast iron. The sealing end is made of cast iron. The heating element is spirally distributed within the cavity and is close to the inner wall of the cavity. An internal hexagonal hole is provided on one side of the sealing end. A wiring hole is provided at one end of the rod body, and an electric wire is disposed within the wiring hole. A sealing sleeve is disposed between the electric wire and the wiring hole. The heat-conducting metal mesh sleeve is made of copper and is welded to the outer wall of the rod body.

[0032] The thermally conductive metal mesh sleeve serves two purposes: improving grip stability and conducting heat. The threaded fit allows for easy unscrewing of the sealing end as needed.

[0033] The beneficial effects of this invention are: by combining the use of pressure sensors, the pressure sensors and the electric oil pump are linked, thereby enabling rapid deceleration when the riding posture is incorrect, reducing the probability of the vehicle overturning.

[0049] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention.

[0051] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0052] As attached Figures 1-13As shown, an all-terrain vehicle includes a frame 9, an engine, a fuel tank, and an electric fuel pump. Wheels 5 are mounted on the frame 9, and each wheel 5 has an agricultural tire. The engine, fuel tank, and electric fuel pump are all mounted on the frame 9. The engine is connected to some of the wheels 5 via a drive shaft. The electric fuel pump is connected to the engine and fuel tank via pipelines. The vehicle also includes foot pedals 6. A saddle 4 is mounted on the frame 9, and a first pressure sensor is mounted on the saddle 4. A positioning rod 7 is mounted on the frame 9. A positioning hole 601 is provided on the foot pedal 6, and the positioning hole 601 is fitted into the positioning rod 7. A second pressure sensor is located between the frame 9 and the foot pedal 6. There are two foot pedals 6, distributed on opposite sides of the frame 9. A second pressure sensor is located between each foot pedal 6 and the frame 9. A steering rod 8 is rotatably mounted on the frame 9, and an encoding sensor 11 is located between the frame 9 and the steering rod 8.

[0053] In this type of all-terrain vehicle, the tires of wheel 5 are agricultural tires used on tractors. These tires have high friction with the ground and strong grip, which ensures that the tires can travel on various rough roads. At the same time, when the engine stops, the vehicle speed will drop quickly due to the strong grip of the tires. Therefore, the all-terrain vehicle can be regarded as a tractor with reduced horsepower, and its off-road performance is excellent.

[0054] In this type of all-terrain vehicle, the electric fuel pump pumps fuel from the fuel tank to the engine's carburetor, thereby driving the engine. The amount of fuel pumped to the engine can be controlled by the electric fuel pump, and the engine stops running when the electric fuel pump stops pumping fuel.

[0055] The specific operating process of this all-terrain vehicle is as follows: When the rider adopts a correct straddle posture, their buttocks are on the saddle 4, at which point the first pressure sensor can detect the pressure value. The rider's two feet are on the two foot pedals 6, allowing the two second pressure sensors to also detect the pressure value. Only when both the first and second pressure sensors detect the pressure value will the onboard computer control the fuel pump to start. If the onboard computer fails to detect the pressure value of either pressure sensor, the fuel pump immediately stops, preventing fuel from being pumped to the engine, causing the engine to quickly shut off, thus achieving rapid deceleration until the vehicle stops. Therefore, this type of vehicle uses a combination of pressure sensors to achieve linkage between the pressure sensors and the fuel pump, thereby enabling rapid deceleration when the riding posture is incorrect, reducing the probability of the vehicle tipping over. If a safe and correct riding posture is not adopted from the beginning, the vehicle will not even be able to start.

[0056] Meanwhile, this type of vehicle further includes an encoding sensor 11 (including but not limited to photoelectric encoding sensor 11) between the frame 9 and the steering rod 8. The function of the encoding sensor 11 is to detect the rotation of the steering rod 8. Because the steering rod 8 needs to rotate relative to the frame 9 when the vehicle needs to turn, the encoding sensor 11 is further installed in this vehicle to monitor the rotation of the steering rod 8. The rotation of the steering rod 8 represents the steering of the front wheels of the vehicle. The on-board computer further uses the rotation of the steering rod 8 detected by the magnetic encoding sensor 11 to adjust the oil speed of the electric fuel pump. Assuming that the pumping speed is A at a certain moment, if the magnetic encoder measures a rotation of 5 degrees, the on-board computer will immediately reduce the pumping speed to 0.8A. If the rotation is 10 degrees, it will immediately reduce to 0.5A. If the measured rotation reaches 20 degrees, it will immediately reduce to the minimum pumping speed B (B is a specific set value, which is set by the manufacturer for the on-board computer at the factory. If 0.8A is already less than the value of B, then the value of B will be maintained). This achieves the setting of the minimum speed for cornering and steering. By using the coded sensor 11, automatic speed reduction is achieved during steering, and a minimum pump oil volume is set, enabling automatic deceleration during steering and reversing, and ensuring that the vehicle does not stop automatically, thereby further improving operational reliability and reducing the probability of overturning.

[0057] As attached Figures 1-6 As shown, it also includes an on-board gyroscope 12, which is mounted on the vehicle frame 9.

[0058] The specific frame 9 has a total of four wheels 5, two front wheels and two rear wheels. The engine is connected to the two rear wheels via a linkage. The entire all-terrain vehicle is a rear-wheel drive vehicle. The vehicle-mounted gyroscope 12 is located between the two front wheels. The function of the vehicle-mounted gyroscope 12 is to detect the tilt of the entire frame 9. By monitoring the vehicle's tilt, the ruggedness and steepness of the road can be determined. For excessively rugged and steep roads, in order to avoid dangerous accidents caused by the user riding on such roads, when the vehicle-mounted gyroscope 12 senses that the vertical tilt of the front of the vehicle during the journey reaches a certain value (the horizontal tilt can cause the steering lever 8 to rotate, which is then sensed by the coding sensor 11), it directly reduces the pump oil volume to the minimum value B, effectively stopping the vehicle directly and avoiding the engine from stopping directly and causing a large rollback.

[0059] As attached Figures 1-6 As shown, a clamping platform 16 is provided on the frame 9, and a storage battery 15 is installed inside the clamping platform 16.

[0060] The function of the clamp 16 is to install the storage battery 15.

[0061] As shown in the attached diagram, a support plate 901 is provided on the frame 9, and a second pressure detection sensor is disposed on the support plate 901. To ensure reliable measurement, multiple second pressure detection sensors are provided on each support plate 901, and the second pressure detection sensors are distributed in a dot matrix pattern.

[0062] As attached Figures 1-6 As shown, it also includes a rear seat frame 2, which is mounted on the frame 9. The frame 9 is equipped with an armrest frame 3. An armrest frame 3 is distributed on each side of the rear seat frame 2. A third pressure sensor is mounted on the rear seat frame 2. A card slot is mounted on the rear seat frame 2.

[0063] The function of the rear seat bracket 2 is to accommodate a passenger. The third pressure sensor detects whether a passenger is seated in the vehicle. If a passenger is seated, the onboard computer directly limits the vehicle's speed based on the maximum fuel pumping speed, thereby limiting the vehicle's speed. The function of the armrest bracket 3 is to provide hand support for passengers, while the card slot is used to insert and attach seat belts when necessary.

[0064] As attached Figures 1-6 As shown, it also includes a tow hook 18, a wide-angle camera 17, and a display screen 13. The wide-angle camera 17, the tow hook 18, and the display screen 13 are all mounted on the vehicle frame 9. The wide-angle camera 17 is electrically connected to the display screen 13 through the vehicle computer.

[0065] The tow hook 18 and the wide-angle camera 17 are both located at the rear of the vehicle frame 9, and the display screen 13 is located at the front of the vehicle frame 9. The display screen 13 is also electrically connected to the vehicle computer and displays the information of the vehicle computer. When this type of vehicle is used as a tow truck, the wide-angle camera 17 can be turned on to obtain image information for the tow hook 18 and the towed vehicle.

[0066] As attached Figure 1 , 7 As shown in Figures 8 and 9, the vehicle also includes a grille-shaped radiator 10 and an intake pipe 19. The grille-shaped radiator 10 is mounted on the frame 9 and has heat dissipation fins arranged on it. One port of the intake pipe 19 is connected to the engine, and the other port of the radiator 10 is located on one side of the heat dissipation fins. A fan 20 is mounted on the frame 9 and is located on the same side of the heat dissipation fins as the intake pipe 19.

[0067] The function of the grille-shaped radiator 10 is to cool the engine coolant.

[0068] Because this type of vehicle often needs to drive on muddy roads, the vehicle will splash mud and dust when driving on muddy roads. After the mud and dust enter the intake pipe 19, they will damage the engine filter. Therefore, in this solution, one of the pipe openings of the intake pipe 19 is detachably connected to the engine intake port by a clamp. The other pipe opening of the intake pipe 19 is located near the cooling fins of the grille-shaped radiator 10. When the vehicle is driving, the airflow flows from the front, passes through the fins, and then flows into the intake pipe 19. In this way, even if the vehicle encounters mud and dust during driving, the arranged cooling fins act as a filter, which can reduce the probability of dust and mud entering the intake pipe 19.

[0069] Meanwhile, in this type of vehicle, the intake pipe 19 and the fan 20 are located on the same side of the heat dissipation fins. When the fan 20 is running, it draws air from one side of the heat dissipation fins to the side of the intake pipe 19. This not only increases the airflow speed and speeds up the heat dissipation efficiency of the heat dissipation fins, but also increases the air intake volume of the intake pipe 19, thereby achieving rapid air intake and ensuring that the intake pipe 19 will not have difficulty in intake due to the obstruction of the heat dissipation fins, and ensuring that the airflow rushes into the intake pipe 19 at a high speed.

[0070] As attached Figure 1 , 7 As shown in Figures 8, 9, 10, and 11, a number of longitudinal baffles 22 and a number of transverse baffles 22 are inserted into the clamping sleeve 21 of the intake pipe 19. The longitudinal baffles 22 are perpendicular to the transverse baffles 22, and the longitudinal baffles 22 are parallel and do not contact each other. The transverse baffles 22 are parallel and do not contact each other. The intake pipe 19 is cylindrical, and a number of semicircular plates 23 are provided on the inner wall of the intake pipe 19. Adjacent semicircular plates 23 do not contact each other. Each semicircular plate 23 forms a clamping groove with the inner wall of the intake pipe 19, and the opening of each clamping groove faces the clamping sleeve 21.

[0071] Specifically, the longitudinal baffle 22 and the transverse baffle 22 on the clamping sleeve 21 form two layers of filters, and these two layers of filters do not have mesh holes. The two layers of filters without mesh holes can prevent small animals from crawling into the air intake pipe 19. Secondly, since there are no mesh holes, the obstruction to airflow is relatively small, ensuring efficient air intake. At the same time, due to the electrostatic effect, the longitudinal baffle 22 and the transverse baffle 22 can adsorb dust and short fibers to a certain extent. When cleaning is required, simply remove the clamping sleeve 21 and wash it clean with a high-pressure water gun.

[0072] Meanwhile, in this design, a clamping groove is formed between each semicircular plate 23 and the inner wall of the intake pipe 19, with the opening of each clamping groove facing the clamping sleeve 21, thus ensuring airflow (airflow direction as shown in the attached diagram). Figure 11(As indicated by the arrow in the image) After entering the intake pipe 19, the air is blocked by the semi-circular plate 23. The presence of the semi-circular plate 23 can further adsorb and purify the dust. At the same time, some water vapor in the airflow will also be trapped by the clamping groove. The water vapor forms water in the clamping groove and is collected by the clamping groove. The dust is further adsorbed and trapped by the water in the clamping groove, thereby playing a role in efficiently purifying the air and maximizing the service life of the engine air filter.

[0073] When cleaning is required, simply disassemble the air intake pipe 19, rinse it with a high-pressure water gun, and then dry it in the sun. Specifically, the air intake pipe 19 can be regarded as being welded together from two semi-circular steel plates. First, the semi-circular plate 23 is welded onto the two semi-circular steel plates, and then the two semi-circular steel plates are welded together.

[0074] As attached Figure 1 , 12 As shown in Figure 13, the system also includes a handlebar 1 and a handlebar lever. The handlebar 1 is made of metal and is fixedly fitted to one end of the steering lever 8. The handlebar 1 is equipped with a brake lever 29, a manual throttle, and a parking handle 25. The handlebar lever has a cavity 2801, which contains a heating element 33 and is filled with heat-conducting oil. The end of the handlebar 1 has a slot. Both the handlebar lever and the handlebar 1 are fitted with a bonding plate 27, which is welded to the handlebar 1. A rigid heat insulation sleeve 32 is provided between the handlebar 1 and the handlebar lever. The electronic control box 24 is also located on the handlebar 1.

[0075] In traditional bicycle handlebars, the handlebar 1 and handlebar stem are integral, either formed from a single high-strength, high-bending piece or directly cast in one piece. However, in this application, the handlebar stem and handlebar 1 are welded together, creating a cutable and replaceable liquid-heated handlebar stem. By grinding away the weld points between the two bonding plates 27, the handlebar stem can be disassembled, replaced with a new one, and then re-welded. Because it receives the heat-conducting oil, the temperature of the entire handlebar stem is uniform. Furthermore, compared to the traditional method of directly installing resistance wires on the handlebar stem, using liquid heat transfer avoids excessively high temperatures at certain points, preventing burns to the user's hands. It also prevents the high temperature of the resistance wire from igniting flammable materials.

[0076] Specifically, in this type of handlebar, the maximum heating temperature of the heat transfer medium oil can be set to no more than 37 degrees Celsius, thus providing the user with the best grip.

[0077] Specifically, the rigid heat insulation sleeve 32 can be a heat insulation sleeve made of ABS engineering plastic. The function of the heat insulation sleeve is to reduce heat convection between the handlebar and the handlebar 1.

[0078] As attached Figure 1 , 12 As shown in Figure 13, the handle includes a rod body 28, a sealing end 31, and a heat-conducting metal mesh sleeve 30. A cavity 2801 is disposed inside the rod body 28. The sealing end 31 is threaded together with the rod body 28. A sealing gasket 34 is disposed between the rod body 28 and the sealing end 31. The rod body 28 is made of cast iron. The sealing end 31 is made of cast iron. The heating tube 33 is spirally distributed inside the cavity 2801. The heating tube 33 is close to the inner wall of the cavity 2801. An internal hexagonal hole 3101 is opened on one side of the sealing end 31. A wiring hole is provided at one end of the rod body 28. A wire is placed in the wiring hole. A sealing sleeve 35 is disposed between the wire and the wiring hole. The heat-conducting metal mesh sleeve 30 is made of copper and is welded to the outer wall of the rod body 28.

[0079] The thermally conductive metal mesh sleeve 30 serves two purposes: to improve grip stability and to conduct heat. The threaded fit allows for easy unscrewing of the sealing end 31 as needed.

[0080] It should be noted that when this type of all-terrain vehicle is not used as a trailer and is not carrying passengers, the maximum speed on paved roads is limited to 50 km / h, while the maximum speed when turning is limited to 10 km / h.
