Description

Technical Field

[0001] This invention relates to the field of motorcycle technology, and in particular to a temperature control system, a motorcycle, and a ventilation method. Background Technology

[0002] Thermal comfort in large-displacement motorcycles has become a key bottleneck restricting the improvement of user experience. Thermal comfort technology for large-displacement motorcycles is also one of the core research directions in the industry, not only meeting users' core needs for safety and comfort, but also directly impacting user experience and safety, especially in high-temperature environments, congested roads, and long-distance riding scenarios, and aligning with the differentiated competitive trend in the high-end motorcycle market.

[0003] Thermal comfort is crucial for motorcycles, directly impacting rider fatigue, focus, and the sustainability of long-distance riding; it's a key indicator of a model's overall performance. Among various motorcycle types, cruisers equipped with V-type engines face particularly severe thermal comfort challenges. This stems from the unique structure of V-type engines, where the rear cylinder is typically located close to the rider's legs and hips, creating a concentrated area of ​​localized high temperature. Furthermore, the narrow body layout and limited aerodynamic design commonly found on cruisers not only place the exhaust system close to the rider but also restrict the airflow's efficiency in cooling the rear cylinder, directly causing the rider to passively absorb a significant amount of waste heat, thus significantly exacerbating thermal discomfort. Therefore, addressing these thermal comfort issues has become one of the core engineering challenges in improving the riding experience of this type of motorcycle.

[0004] Therefore, how to improve the driver's thermal comfort to enhance the driver's driving experience is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0060] The purpose of this invention is to provide a temperature control system, a motorcycle, and a ventilation method that can improve the driver's thermal comfort and thus enhance the driver's driving experience.

[0061] Please see Figure 1 , Figure 2 and Figure 3 To achieve the above objectives, the present invention provides a temperature control system installed on a motorcycle. The motorcycle is equipped with a V-type engine 300, which is located below a fuel tank 900, with a seat 800 behind the fuel tank 900. The V-type engine 300 includes a front cylinder 310 and a rear cylinder 320 located behind the front cylinder 310. The front cylinder 310 is connected to a front cylinder exhaust pipe 330, and the rear cylinder 320 is connected to a rear cylinder exhaust pipe 340. A radiator 500 is located in front of the front cylinder 310 to dissipate some of the heat from the front cylinder 310 and the front cylinder exhaust pipe 330. The temperature control system includes an air intake duct and a fan cover 200. The air intake duct is fixed to the motorcycle body. The air intake duct is located inside a body hood cover 700. The air intake duct can be a tubular structure independent of the body hood cover 700, or it can be an integrated structure integral with the body hood cover 700.

[0062] Please see Figure 4 , Figure 5 and Figure 6 The air intake duct includes a cooling air duct 110, a hot air duct 120, and a conveying duct 130. The inlet of the hot air duct 120 is located behind the motorcycle's radiator 500, and can draw in the exhaust air from the radiator 500 and the hot air near the exhaust pipe 330 of the engine's front cylinder 310 as a heating source. The inlet of the cooling air duct 110 is located at the front of the vehicle, ensuring that the air temperature drawn in by the cooling air duct 110 is ambient temperature. The inlet of the conveying duct 130 can be selectively connected to the outlet of the cooling air duct 110 or the outlet of the hot air duct 120.

[0063] Please see Figures 7 to 14 The fan cover 200 is fixed to the motorcycle body and located at the angle between the engine 300 and the motorcycle body, making it easy to install without affecting the appearance. The fan cover 200 includes a cavity 210, a cover 290 for sealing the cavity 210, a first air inlet assembly, a power unit 230, a first air outlet assembly 240, and a second air outlet assembly 250. The cover 290 has an air inlet 291 located at the top of the cover 290 and communicating with the outlet of the conveying channel 130. The first air inlet assembly is located on the front end face of the fan cover 200, the first air outlet assembly 240 is located on the rear end face of the fan cover 200, and the second air outlet assembly 250 is located on the side end face of the fan cover 200. The power unit 230 drives the gas from the conveying channel 130 into the cavity 210 and discharges it along the first air outlet assembly 240 and / or the second air outlet assembly 250. The power unit 230 can be configured as a fan, specifically including a fan body and a mounting base connected to the fan body. The mounting base fixes the position of the fan body. Alternatively, the power unit 230 can also be configured as a fan with a suction function. It should be noted that any solution equivalent to this embodiment that achieves the same effect is within the protection scope of this invention.

[0064] The temperature control system includes an air intake duct for fixing to the motorcycle body and a fan shroud 200 for fixing to the motorcycle body and located at the angle of the motorcycle engine 300. A power unit 230 housed within the fan shroud 200 drives the gas from the delivery duct 130 into the cavity 210 and out along the first air outlet assembly 240 and / or the second air outlet assembly 250. Along the first air outlet assembly 240, the gas can flow to the rear of the fan shroud 200 to blow towards the driver's legs and / or the engine rear cylinder 320; along the second air outlet assembly 250, the gas can flow to the side surface of the fan shroud 200 to blow towards the driver's legs. The inlet of the air intake duct can be connected to the outlet of the cooling air duct 110 or the outlet of the hot air duct 120 as needed, allowing the driver to select different ventilation modes to heat or cool their legs according to their subjective needs. Specifically, when heating is required, the inlet of the air intake duct is connected to the hot air duct 120, and the power unit 230 is activated, allowing hot air from behind the radiator 500 to be delivered to the driver's legs through the air intake duct and fan shroud 200, thus raising the temperature of the driver's legs. When cooling is required, the inlet of the air intake duct is connected to the cooling air duct 110, and the power unit 230 is activated, allowing cooling air to be delivered to the driver's legs or the rear cylinder 320 of the engine through the air intake duct and fan shroud 200, thereby reducing the temperature of both the driver's legs and the rear cylinder 320. Furthermore, when cooling of the legs or the rear cylinder 320 is required, air can be drawn into the cavity 210 through the first air intake assembly located on the front surface of the fan shroud 200, and exhausted to the legs or the rear cylinder 320 through the first air outlet assembly 240. This configuration improves the driver's thermal comfort, thereby enhancing the driver's driving experience.

[0065] In one possible implementation, a knob assembly 400 is provided at the inlet of the conveying channel 130. The knob assembly 400 includes a valve body 410 and a first power source 420. The valve body 410 has a rotating shaft that is throttlely connected to the output end of the first power source 420, a first valve 411 fixedly connected to the rotating shaft, and a second valve 412 fixedly connected to the rotating shaft. The rotating shaft is located at the junction of the cooling air channel 110 and the hot air channel 120. The first power source 420 is used to drive the rotating shaft to rotate, thereby causing the first valve 411 to block the outlet of the hot air channel 120 or the second valve 412 to block the outlet of the cooling air channel 110. When the first valve 411 is in the closed state of the hot air outlet, the second valve 412 is located in the hot air channel 120 to keep the cooling air channel 110 unobstructed; when the second valve 412 is in the closed state of the cooling air outlet, the first valve 411 is located in the cooling air channel 110 to keep the hot air channel 120 unobstructed. The first power source 420 can be, but is not limited to, a micro motor. The angles of the first valve 411 and the second valve 412 can be adjusted according to the angle between the outlet direction of the hot air channel 120 and the outlet direction of the cooling air channel 110. This ensures that when the second valve 412 is against the inner wall of the hot air channel 120, the first valve 411 is in a closed state for the outlet of the hot air channel 120; and when the first valve 411 is against the inner wall of the cooling air channel 110, the second valve 412 is in a closed state for the outlet of the cooling air channel 110. This allows for the closure of either the outlet of the hot air channel 120 or the outlet of the cooling air channel 110 via the valve body 410, while avoiding interference with the connection between the other outlet of the hot air channel 120 and the delivery channel 130.

[0066] In one possible implementation, a first opening 260 is provided on the front side of the fan decorative cover 200. A first air inlet assembly is installed at the first opening 260. The first air inlet assembly includes an air guide plate 220 and a second power source. The air guide plate 220 is movably connected to the fan decorative cover 200 and is used to block or open the first opening 260. The output end of the second power source is driven to the air guide plate 220, and the second power source is used to drive the air guide plate 220 to move relative to the fan decorative cover 200. The second power source can be, but is not limited to, a micro motor or a cylinder. When the second power source drives the air guide plate 220 to block the first opening 260, the first opening 260 is not connected to the outside of the fan decorative cover 200, and ambient gas cannot enter the cavity 210 through the first opening 260. When the second power source drives the air guide plate 220 to open the first opening 260, the first opening 260 is connected to the outside of the fan decorative cover 200, and ambient gas can enter the cavity 210 through the first opening 260.

[0067] Please see Figure 15In one possible implementation, the rear end face of the fan decorative cover 200 has a second opening 270 for mounting the first air outlet assembly 240. The first air outlet assembly 240 includes a first housing 241, a first drive member 242 connected to the first housing 241, a plurality of first grille plates 243 spaced apart in the height direction and rotatably connected to the first housing 241, and a first transmission link 244 drivingly connected to all the first grille plates 243 and drivingly connected to the output end of the first drive member 242. The first drive member 242 can drive all the first grille plates 243 to rotate synchronously through the first transmission link 244. The first drive member 242 can be, but is not limited to, a micro motor, and can drive the first grille plates 243 to rotate vertically from 0° to 180° to adjust the air outlet direction according to the driver's needs. When the rotation angle of the first grille plates 243 is 0° or 180°, all the first grille plates 243 are in the same vertical plane and are in a closed state.

[0068] In another possible implementation, the output end of the first drive member 242 is driven to one of the first grille pieces 243, and the first transmission link 244 is connected to all the first grille pieces 243.

[0069] In one possible implementation, the first air outlet assembly 240 further includes a second drive member 245 connected to the first housing 241, a plurality of second grille plates 246 spaced horizontally and rotatably connected to the first housing 241, and a second transmission link drivingly connected to all the second grille plates 246 and drivingly connected to the output end of the second drive member 245. The second drive member 245 can drive all the second grille plates 246 to rotate synchronously via the second transmission link. The second drive member 245 can be, but is not limited to, a micro motor, and can drive the second grille plates 246 to rotate left and right by 0-180° to adjust the air outlet direction left and right according to the driver's needs. When the rotation angle of the second grille plates 246 is 0° or 180°, all the second grille plates 246 are in the same vertical plane and are in a closed state.

[0070] In another possible implementation, the output end of the second drive member 245 is driven to one of the second grille pieces 246, and the second drive linkage is connected to all the second grille pieces 246. The output end of the second drive member 245 can drive the second grille piece 246 connected to it to rotate, and drive the remaining second grille pieces 246 to rotate synchronously through the second drive linkage, so that all the second grille pieces 246 have the same orientation, and adjust the air outlet direction left and right.

[0071] Please see Figure 16 In one possible implementation, the side end face of the fan decorative cover 200 has a third opening 280 for mounting the second air outlet assembly 250. The second air outlet assembly 250 includes a second housing 251, a third drive member 252 connected to the second housing 251, a plurality of third grille plates 253 spaced apart in the height direction and rotatably connected to the second housing 251, and a third transmission link 254 drivingly connected to all the third grille plates 253 and drivingly connected to the output end of the third drive member 252. The third drive member 252 can drive all the third grille plates 253 to rotate synchronously through the third transmission link 254. The third drive member 252 can be, but is not limited to, a micro motor, and can drive the third grille plates 253 to rotate vertically from 0° to 180° to adjust the air outlet direction according to the driver's needs.

When the rotation angle of the fourth grille plates 256 is 0° or 180°, all the fourth grille plates 256 are in the same vertical plane and are in a closed state.

[0074] In another possible implementation, the output end of the fourth drive member 255 is driven to one of the fourth grille pieces 256, and the fourth transmission link is connected to all the fourth grille pieces 256. The output end of the fourth drive member 255 can drive the fourth grille piece 256 connected to it to rotate, and drive the remaining fourth grille pieces 256 to rotate synchronously through the fourth transmission link, so that all the fourth grille pieces 256 have the same orientation, and adjust the air outlet direction left and right.

[0075] Please see Figure 17 , Figure 18 and Figure 19 In one possible implementation, the temperature control system further includes an airflow guide decorative cover 600, which is connected to the motorcycle body and located below the motorcycle seat 800. The airflow guide decorative cover 600 is spaced apart from the fan decorative cover 200. The airflow guide decorative cover 600 includes an outer decorative cover 610 and an inner decorative cover 620, forming an airflow channel 630 between them. The airflow channel 630 allows some of the gas discharged from the first air outlet assembly 240 to pass through, thus streamlining the airflow and preventing turbulence that could cause other components or parts of the rider to overheat. After the airflow is directionally adjusted by the first air outlet assembly 240, a portion of the airflow is discharged through the airflow channel 630 in the middle of the airflow guide decorative cover 600, while another portion continues to cool the rear cylinder exhaust pipe 340 from below the airflow guide decorative cover 600. The airflow guide decorative cover 600 ensures that the middle airflow channel 630 remains unobstructed. Both the outer decorative cover 610 and the inner decorative cover 620 can be designed to match the overall vehicle styling, ensuring a harmonious and consistent appearance. It should be noted that the temperature control system in this application, which includes an air intake channel, a fan decorative cover 200, and an airflow guide decorative cover 600, can be arranged on both the left and right sides of the motorcycle, and the two temperature control systems are independent of each other and can be controlled by the driver individually to improve the user experience.

[0076] The temperature control system proposed in this application can dynamically adjust the temperature and integrates with the motorcycle's design, preserving its aesthetic appeal. It can handle different temperature environments, cover various riding conditions, and address the thermal comfort needs of riders of different body types. Specifically, it can raise or lower the temperature of the rider's legs based on parameters such as ambient temperature and the engine's 300cc cylinder head temperature, providing a better thermal comfort experience in different seasons. Temperature regulation is achieved by switching between hot and cooling air and adjusting the fan speed, enhancing rider comfort under various riding conditions. The air outlet assembly is adjustable, allowing for vertical and horizontal adjustments, enabling the rider to customize the airflow angle for their comfort. This significantly improves the thermal comfort experience for riders of motorcycles equipped with a V-type 300cc engine.

[0077] The control strategy includes selecting the air duct and opening / closing the fan based on vehicle speed, switching the air duct at different speeds. This strategy also includes switching the cooling / heating mode and air duct based on ambient temperature, engine 300 surface temperature, body panel temperature, and engine 300 coolant temperature, as well as providing multi-level adjustment of the airflow in the up / down and left / right directions, allowing the driver to customize a suitable airflow mode. Specifically, based on vehicle speed, ambient temperature, and driver body type, the system automatically adjusts the temperature of different vehicle components and different parts of the driver's body, reducing the temperature of vehicle components and creating a comfortable environment for the human body. In high-temperature environments (above 35℃) and when the vehicle is operating at high speed, air convection can remove most of the heat from the vehicle body. However, the surface temperature of the rear engine 300 cylinder is relatively high. Tests show that using the temperature control system provided in this application, the surface temperature of the rear engine 300 cylinder can be reduced by approximately 5-10℃ during high-speed vehicle operation. In high-temperature environments, when the vehicle is operating at low speed, the human body can feel the heat from the vehicle's heat-generating components (engine 300, radiator 500 air outlet, exhaust pipe 340, etc.), causing the driver's leg temperature to rise continuously. Tests show that activating this temperature control system after low-speed riding can reduce the driver's leg temperature by approximately 6-10°C. In high-temperature environments, when the vehicle is idling after high-speed driving, heat accumulates from the vehicle's heat-generating components (engine 300, radiator 500 air outlet, exhaust pipe, etc.), causing the driver's leg temperature to rise rapidly. Tests show that after high-speed driving, the driver's leg temperature rises rapidly at idle; activating this temperature control system reduces the maximum temperature of the driver's legs by 18-38°C. In low-temperature environments (below 15°C), this temperature control system has been verified to increase the driver's leg temperature by approximately 3-6°C at high speeds, approximately 8-12°C at low speeds, and approximately 20-25°C when the vehicle is idling. It has a good cooling or warming effect on drivers of different body types and in different postures at idle (standing, sitting, single-leg support, etc.), keeping the human body in a suitable temperature environment.

[0078] Based on the above, this application also provides a motorcycle, including a body and a temperature control system of any of the above embodiments. The temperature control system is installed on the body, and the motorcycle naturally has all the beneficial effects of the temperature control system. The remaining structure of the motorcycle can refer to the prior art as long as it can achieve the above objectives.

[0079] Based on the above, this application also provides a ventilation method applicable to the temperature control system of any of the above embodiments. The operation buttons are integrated into the motorcycle's handlebars, which include a cooling / heating mode activation and switching button, an airflow direction adjustment button for the first air outlet assembly 240, and an airflow direction adjustment button for the second air outlet assembly 250. Other operations are automatically adjusted based on signals such as temperature and vehicle speed. The ventilation method includes: acquiring the temperature mode signal of the temperature control system selected by the user and the motorcycle's operating mode. The motorcycle's operating modes are divided into high-speed mode, low-speed mode, and idle mode. In one embodiment, high-speed mode is a vehicle speed greater than or equal to 60 km / h, low-speed mode is a vehicle speed greater than 0 km / h and less than 60 km / h, and idle mode is a vehicle speed of 0 km / h. The speed ranges for each mode can also be redefined according to actual needs, for example, determined after calibration based on the vehicle's heat generation.

[0080] Please see Figure 20 , Figure 21 and Figure 22 If the temperature mode is cooling mode and the operating mode is high-speed mode, the first air intake component 240 is opened, the second air outlet component 250 is closed, and the power unit 230 is shut down. If the operating mode is low-speed mode, the first air intake component is closed, the inlet of the conveying channel 130 is connected to the outlet of the cooling air channel 110, the first air outlet component 240 is closed, the second air outlet component 250 is opened, and the power unit 230 is operated. If the operating mode is idle mode, the first air intake component is closed, the inlet of the conveying channel 130 is connected to the outlet of the cooling air channel 110, the first air outlet component 240 is opened, the second air outlet component 250 is closed, and the power unit 230 is operated.

[0081] When the temperature mode is cooling mode and the operating mode is high-speed mode, the first air outlet assembly 240 adjusts the airflow to blow towards the engine rear cylinder 320. The adjustment angle of the first air outlet assembly 240 varies depending on the vehicle model and needs to be calibrated according to the actual vehicle. For example, on a certain motorcycle, adjusting the first grille 243 to 30° provides the best cooling effect for the engine rear cylinder 320. This mode mainly utilizes the cooling airflow from high-speed travel to cool the engine rear cylinder 320. When the driver wants to further improve the cooling effect, the power unit 230 can also be activated as needed. The control module drives the fan motor to dynamically adjust the fan speed based on the temperature feedback from the cylinder head surface temperature sensor and the water temperature sensor of the engine rear cylinder 320. The adjustment is based on the temperature-fan speed curve, which is calibrated through a large number of test results. The general testing method is to monitor the temperature of the tester's legs and the engine 300 cylinder head through sensors, adjust the fan speed to control the airflow, and combine the driver's subjective temperature feedback to finally form the corresponding temperature-fan speed curve.

[0082] The temperature mode is cooling mode. In low-speed mode, the second air outlet assembly 250 can be adjusted according to the position of the rider's legs for different body types. It can also be set to oscillate up / down and forward / backward. At low speeds, the cooling airflow is low, which is insufficient for cooling the rider's legs, especially the back pressure areas such as the inner thighs near the vehicle body. In low-speed mode, the power unit 230 draws cooling air from the front of the vehicle to cool the rider's legs. Within this speed range, the engine rear cylinder head 320 is the primary source of temperature rise in the rider's legs. The control module dynamically adjusts the fan speed based on the temperature feedback from the engine rear cylinder head surface temperature sensor and the coolant temperature sensor. Similarly, the temperature-fan speed curve for this speed range has been calibrated through extensive testing.

[0083] The temperature mode is cooling mode. When the operating mode is idle mode, the first air outlet assembly 240 adjusts the airflow to blow between the rear cylinder exhaust pipe 340 and the airflow guide decorative cover 600. The driver can also customize the airflow direction. In idle mode, the rear cylinder exhaust pipe 340 and the engine rear cylinder 320 accumulate a lot of heat. This heat is continuously radiated to nearby covers and the human body, especially the airflow guide decorative cover 600, which is a part in direct contact with the human body. Without this system, these parts and the driver's legs would absorb a lot of radiant heat, and the temperature would rise rapidly, resulting in a poor driving experience. In this mode, cooling air is drawn from the front of the vehicle. The airflow discharged through the first air outlet assembly 240 is divided into two paths. The first path is that the cooling air first flows through the rear cylinder exhaust pipe 340, carrying away some heat, and then is discharged from the airflow channel 630 in the middle of the airflow guide decorative cover 600. The second path is that the cooling air first flows through the rear cylinder exhaust pipe 340 and then flows into the channel between the airflow guide decorative cover 600 and the rear cylinder exhaust pipe 340 to continue cooling the middle and rear sections of the exhaust pipe. At idle, the cylinder head of the engine rear cylinder 320 and the exhaust pipe 340 of the rear cylinder are the main sources of temperature rise in the driver's legs. The control unit mainly drives the fan motor to dynamically adjust the fan speed based on the temperature feedback from the cylinder head surface temperature sensor, water temperature sensor and exhaust pipe 340 surface sensor of the engine rear cylinder 320. Similarly, the temperature-fan speed curve at idle is calibrated through a large number of tests.

[0084] Please see Figure 23 and Figure 24 If the temperature mode is heating mode and the operating mode is high-speed mode, the first air inlet component is closed, the inlet of the conveying channel 130 is connected to the outlet of the hot air channel 120, the first air outlet component 240 is closed, the second air outlet component 250 is opened, and the power unit 230 is operated. If the operating mode is low-speed mode, the first air inlet component is closed, the inlet of the conveying channel 130 is connected to the outlet of the hot air channel 120, the first air outlet component 240 is closed, the second air outlet component 250 is opened, and the power unit 230 is operated. If the operating mode is idle mode, the first air inlet component is closed, the inlet of the conveying channel 130 is connected to the outlet of the hot air channel 120, the first air outlet component 240 is opened, the second air outlet component 250 is closed, and the power unit 230 is operated.

[0085] During high-speed riding, the cooling airflow is high, and apart from the engine rear cylinder 320, almost no other heat from the vehicle body is transferred to the rider, requiring a large amount of heating. During low-speed riding, the cooling airflow from the ride is low. At this time, the rider's leg temperature is slightly higher than at high speed, but still not enough to make the rider feel warm. The required heating is moderate, and the rider's legs are located on the side of the fan shroud 200. In this case, closing the first air outlet assembly 240 and opening the second air outlet assembly 250 helps to exhaust hot air to the rider's legs. In idle mode, the heat from the engine rear cylinder 320 and exhaust pipe will radiate to the rider, and the rider's legs will heat up quickly. The required heating is small, and in idle mode, the rider's legs are vertical to maintain the motorcycle's posture. The rider's legs are located behind the fan shroud 200. In this case, opening the first air outlet assembly 240 and closing the second air outlet assembly 250 helps to exhaust hot air to the rider's legs.

[0086] The airflow driven by the power unit 230 is related to the vehicle's speed, and the speed or volume of the hot air should decrease with the vehicle speed to maintain the rider's leg temperature within a comfortable range under various riding conditions. The fan speed is adjusted according to vehicle speed and temperature, being directly proportional to vehicle speed and inversely proportional to temperature, with the specific relationship related to the motorcycle's aerodynamics and thermal management characteristics. The rider can adjust the opening and closing of the first air outlet assembly 240 and the second air outlet assembly 250 according to different riding positions, and can also customize the airflow direction of the first air outlet assembly 240 and the second air outlet assembly 250. The fan speed is adjusted based on vehicle speed, rear cylinder head temperature, and rear cylinder exhaust pipe 340 temperature, with the dynamic speed change curve for the heating mode calibrated through extensive testing. Furthermore, the fan speeds on the left and right sides of the motorcycle can be dynamically adjusted separately according to the arrangement of the front cylinder exhaust pipe 330 and the rear cylinder exhaust pipe 340.
