Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a motorcycle. Background Art

[0002] The main function of the motorcycle airfoil is to reduce the lift of the front wheel at high speeds, increase the downward pressure of the front wheel, and improve the aerodynamic stability of the vehicle at high speeds. Most of the airfoils used in mainstream models on the market currently are fixed airfoils and cannot adjust the angle of the airfoil deployment according to different working conditions. Although it can improve the aerodynamic stability of the motorcycle at high speeds, during the starting and accelerating stage and the low-speed driving stage of the motorcycle, the presence of the airfoil increases the resistance of the motorcycle, which not only affects the acceleration performance of the whole vehicle but also increases energy consumption. Summary of the Invention

[0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a motorcycle with better high-speed stability and lower air resistance during the starting and accelerating stage and the low-speed driving stage.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

The running assembly includes a front wheel and a rear wheel; the power assembly is drivingly connected to at least one of the front wheel and the rear wheel; the body cover at least partially covers the frame and includes a fairing disposed at the front of the motorcycle; the detection assembly is used to detect the vehicle speed of the motorcycle;

[0006] The motorcycle further includes an airfoil assembly, the airfoil assembly includes an airfoil, a driving member, a connecting rod, a fixing plate, a rotating shaft, and a controller. The fixing plate is fixedly connected to the fairing, the airfoil is connected to the fixing plate through the rotating shaft, the axis of the rotating shaft is substantially parallel to the vehicle width direction of the motorcycle, and the airfoil can rotate around the axis of the rotating shaft; the connecting rod connects the airfoil and the driving member, and the connecting rod can drive the airfoil to rotate around the rotating shaft; the driving member is installed inside the fairing, and the controller can also obtain the vehicle speed information from the detection assembly;

[0007] When the vehicle starts, the airfoil is in a folded state. When the vehicle speed exceeds a certain speed threshold, the controller controls the driving member to operate, drives the connecting rod to actuate, and makes the airfoil rotate around the rotating shaft, so that the airfoil is in an unfolded state.

[0008] Further, a plane perpendicular to the width direction of the motorcycle and passing through the center of the width of the motorcycle is defined as the longitudinal center plane of the motorcycle. The angle formed by the fixing plate and the longitudinal center plane is greater than or equal to 5 degrees and less than or equal to 45 degrees. When the wind wing is in the folded state, the wind wing is substantially parallel to the fixing plate. When the wind wing is in the unfolded state, the angle formed by the wind wing and the fixing plate is greater than 0 degree and less than or equal to 90 degrees.

[0009] Further, the wind wing includes an extending section extending outside the fairing. At the foremost side of the motorcycle, the distance from the outermost end of the extending section of the wind wing to the motorcycle is greater than or equal to 5 cm and less than or equal to 20 cm.

[0010] Further, the wind wing is installed at the foremost part of the motorcycle.

[0011] Further, the surface of the wind wing close to the fixing plate is recessed inward.

[0012] Further, one end of the wind wing farther from the longitudinal center plane is folded downward to form a folding section.

[0016] Further, the detection component is selected from at least one of the following: wheel speed sensor, body control module (BCM), engine electronic control module (ECM), microcontroller (MCU), anti-lock braking system (ABS) of an automobile, or body stability control (MSC). In this application, a combined structure of a wind wing and a fixing plate is adopted, and a structure in which a movable connecting rod pulls and pushes the wind wing to rotate around a rotating shaft, enabling the wind wing to have two states of folding and unfolding, which can realize the switching between drag reduction of the wind wing and a normal attitude, enabling the motorcycle to achieve drag reduction in a low-speed attitude, having good acceleration performance, having a certain downward pressure to maintain high-speed stability in a high-speed attitude, and having good aerodynamic stability.

[0026] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0027] For the sake of clearly explaining the technical solution of the present invention, the front side, rear side, left side, right side, upper side, and lower side as shown in Figure 1 are also defined. It can be understood that the front-rear direction in the embodiments of the present application refers to the length direction of the motorcycle, the left-right direction refers to the width direction of the motorcycle, and the up-down direction refers to the height direction of the motorcycle.

[0028] As shown in Figure 1 , a motorcycle 100 includes a frame 11, a traveling assembly 12, a power assembly (not shown in the figure), a body covering 13, and a detection assembly 14. The motorcycle 100 can be a fuel-driven motorcycle, an electric motorcycle, or a hybrid motorcycle. The motorcycle 100 can be a two-wheeled motorcycle, a three-wheeled motorcycle (including a regular three-wheeled motorcycle and a reverse three-wheeled motorcycle), or a four-wheeled motorcycle (for example, an all-terrain vehicle ATV). The traveling assembly 12 includes at least one front wheel 121 and at least one rear wheel 122. The power assembly is drivingly connected to one of the front wheel 121 and the rear wheel 122. The power assembly can be an engine or a combination of a battery and a driving member.

[0029] The body covering 13 at least partially covers the frame 11 and includes a fairing 131 and a wind wing assembly 132 provided at the front of the motorcycle 100. The body covering 13 can be a plastic part, a metal part, or made of carbon fiber material. The wind wing assembly 132 is connected to the fairing 131.

[0030] In some embodiments, as shown in Figure 1 and Figure 2As shown in the figure, the fairing 131 includes a first fairing 1311, a second fairing 1312, a third fairing 1313, a fourth fairing 1314, a fifth fairing 1315, and a sixth fairing 1316. The fourth fairing 1314 is fixedly installed on the frame 11. The fifth fairing 1315 is installed above the fourth fairing 1314. The sixth fairing 1316 is installed at the front end of the fourth fairing 1314. The first fairing 1311 is installed at the front end of the sixth fairing 1316. The third fairing 1313 is installed above between the sixth fairing 1316 and the fifth fairing 1315. The second fairing 1312 is installed on the side of the sixth fairing 1316 and the fifth fairing 1315. The fairing 131 is preferably made of lightweight materials, such as plastic parts, aluminum, titanium metal materials, carbon fiber, composite materials, etc., to reduce the weight, reduce the load of the whole vehicle, and reduce the wind resistance of the motorcycle 100. The fairing 131 is composed of independent parts. Compared with the integral fairing on the existing motorcycle, when the motorcycle falls, only the damaged part of the fairing can be replaced, instead of replacing the whole fairing 131, which is convenient for maintenance. In addition, when multiple fairings are combined together, the colors are rich, and a unique shape can be formed, improving the aesthetics of the motorcycle 100. Define a plane perpendicular to the width direction of the motorcycle and passing through the center of the width of the motorcycle as the longitudinal center plane 101 of the motorcycle. The angle formed by the second fairing 1312 and the longitudinal center plane 101 is greater than or equal to 5 degrees and less than or equal to 45 degrees, which is more conducive to guiding the wind at the front end of the vehicle head to both sides of the motorcycle 100, and is beneficial to reducing the wind resistance; in addition, the angled setting makes the vehicle head part of the motorcycle 100 have a unique shape, improving the aesthetics of the motorcycle 100.

[0031] In some embodiments, as Figure 3 shown, the wing assembly 132 includes a wing 1321, a driving member 1322, a connecting rod 1323, and a fixing plate 1324. The wing 1321 extends outward from the body of the motorcycle 100. The wing 1321 is connected to the fixing plate 1324 through a rotating shaft 1325, and the fixing plate 1324 is connected below the second fairing 1312. The end of the rotating shaft 1325 is axially limited by a retaining ring 1326. Define a plane perpendicular to the width direction of the motorcycle and passing through the center of the width of the motorcycle as the longitudinal center plane 101 of the motorcycle. The angle formed by the fixing plate 1324 and the longitudinal center plane 101 is greater than or equal to 5 degrees and less than or equal to 45 degrees, so that the fixing plate 1324 is adapted to the overall shape of the fairing 131, improving the aesthetics. The angled setting between the fixing plate 1324 and the longitudinal center plane 101 guides the wind at the front end of the vehicle head to both sides of the motorcycle 100, which is beneficial to reducing the wind resistance. The structure in which the fixing plate 1324 is combined with the fairing 131 enables the wing 1321 to be completely exposed, facilitating disassembly and convenient for maintenance.

[0032] AsFigure 3 and Figure 4 As shown, in some embodiments, the airfoil 1321 includes a folded state (as shown in Figure 3 ) and an unfolded state (as shown in Figure 4 ). When the airfoil 1321 is in the folded state, the airfoil 1321 is substantially parallel to the fixed plate 1324. When the airfoil 1321 is in the unfolded state, the angle formed by the airfoil 1321 and the fixed plate 1324 is greater than 0 degrees and less than or equal to 90 degrees. In the present application, the angle of the airfoil 1321 can be adjusted according to the vehicle speed. For example, when the vehicle starts, the vehicle speed is low, and the airfoil 1321 is in the folded state, reducing the resistance brought by the airfoil 1321 and preventing the airfoil 1321 from being damaged by collision. When the vehicle speed exceeds a certain speed threshold, the airfoil is in the unfolded state, providing a downward pressure on the wheels, reducing the front wheel lift at high speeds, and improving the aerodynamic stability of the vehicle at high speeds. In some embodiments, the speed threshold is greater than or equal to 60 km and less than or equal to 100 km.

[0033] In some embodiments, the airfoil 1321 includes a protruding section 1321a that protrudes outside the fairing 131 and a folded section 1321b formed by folding downward. At the frontmost side of the motorcycle 100 (as shown in Figure 2 ), the distance D from the outermost end of the protruding section 1321a of the airfoil to the motorcycle 100 is greater than or equal to 5 cm and less than or equal to 20 cm. Preferably, the distance D from the outermost end of the protruding section 1321a of the airfoil to the motorcycle 100 is greater than or equal to 8 cm and less than or equal to 15 cm. More preferably, the distance D from the outermost end of the protruding section 1321a of the airfoil to the motorcycle 100 is equal to 10 cm. When the airfoil 1321 is in the unfolded state, if the protruding length of the protruding section 1321a is too long, greater than 20 cm, the resistance brought by the airfoil 1321 itself and the air above the airfoil 1321 will increase, and thus the wind resistance of the motorcycle 100 will increase. If the protruding length of the protruding section 1321a is too short, less than 5 cm, the downward pressure brought by the airfoil 1321 itself and the air above the airfoil 1321 will be insufficient, and it cannot provide sufficient downward pressure at high speeds, affecting the high-speed stability of the motorcycle 100.

[0034] In some embodiments, the surface of the airfoil 1321 close to the fixed plate 1324 is recessed inward, that is, when the airfoil 1321 is in the unfolded state. The upper surface of the airfoil 1321 is recessed downward to form a recessed portion. The existence of the recessed portion enables more air to gather on the upper surface of the airfoil when the airfoil 1321 is in the unfolded state, so that a greater downward pressure can be provided, and the stability of the motorcycle 100 during high-speed driving can be improved to a greater extent.

[0035] In some embodiments, one end of the wing 1321 further away from the longitudinal center plane is folded downward to form a folded section, which effectively eliminates the end plate effect of the tip of the wing and stabilizes the wind resistance of the motorcycle 100.

[0036] In some embodiments, the wing 1321 is installed at the front of the vehicle. This arrangement makes the force arm of the wing acting on the center of mass of the motorcycle 100 the longest, which is more conducive to the driving stability of the motorcycle 100. In some embodiments, the wing 1321 is preferably made of lightweight materials, such as plastic, aluminum, titanium metal materials, carbon fiber, composite materials, etc., to reduce weight and reduce the load of the entire vehicle.

[0037] like Figure 5 As shown, in some embodiments, the connecting rod 1323 movably connects the wind wing 1321 and the driving member 1322 and can drive the wind wing 1321 to rotate around the rotating shaft 1325. The wind wing extension section 1321a is movably connected to the connecting rod 1323 through a flat head with a hole positioning pin, and a cylindrical pin is used at the end of the flat head with a hole positioning pin for anti-dropping and limiting. The other end of the connecting rod 1323 is movably connected to the eccentric shaft of the driving member 1322, and a cylindrical pin is used axially for anti-dropping and limiting. Fisheye joints are used at both ends of the connecting rod 1323. A limiting member 1327 is fixedly installed above the eccentric shaft of the driving member 1322. Optionally, the limiting member 1327 can be a clamp-shaped limiting block. The clamps on both sides are different. The higher side of the clamp prevents the wind wing 1321 from being subjected to force so that the connecting rod 1323 swings a large amount in the unfolding direction, and the lower side of the clamp prevents the wind wing 1321 from being subjected to force so that the connecting rod 1323 swings a large amount in the folding direction. The movable link 1323 drives the wind blade 1321 to rotate around the rotating shaft 1325, and has a simple structure, fast response speed, and is easy to arrange. The movable link 1323 uses a fisheye joint to convert the angle, and the problem of swing clearance in the fisheye joint activity is solved by using a limiter 1327. The assembly and disassembly is simple, maintenance is convenient, and maintenance of the driving member 1322 is also convenient.

[0038] In some embodiments, the middle part of the connecting rod 1323 is thinner than the two ends and the connecting rod 1323 is preferably made of brittle material. When the connecting rod 1323 drives the wind blade 1321 to rotate and change state, if the connecting rod 1323 is hit by external force, since the middle part of the connecting rod is thinner and made of brittle material, the connecting rod 1323 breaks preferentially from the middle part to protect the internal driving device 1322 from being damaged. In some embodiments, the connecting rod 1323 can be a mechanical connecting rod device such as a crank rocker mechanism, a double crank mechanism, and a double rocker mechanism.

[0039] In some embodiments, the driving member 1322 is installed inside the fairing 131. The presence of the fairing 131 can protect the driving member 1322. The driving member 1322 includes a controller 1328 that can control the operation of the driving member 1322. The controller 1328 can also obtain real-time vehicle speed information from the detection component 14 and can determine whether to deploy the airfoil 1321 based on the obtained real-time vehicle speed information.

[0040] Specifically, when the vehicle 100 starts, the airfoil 1321 is defaulted to the folded state. At this time, folding the airfoil 1321 in the low-speed section can reduce the wind resistance and improve the acceleration performance of the motorcycle 100 during acceleration. After the vehicle starts, the detection component 14 begins to detect real-time vehicle speed information. As the vehicle speed increases during driving, the controller 1328 can also obtain real-time vehicle speed information from the detection component 14 and can determine whether to deploy the airfoil 1321 based on the obtained real-time vehicle speed information. When the vehicle speed exceeds the speed threshold, the controller 1328 controls the driving member 1322 to operate, driving the link 1323 to actuate. The actuation of the link causes the airfoil 1321 to rotate around the rotation shaft 1325, bringing the airfoil 1321 into the deployed state. As the motorcycle 100 continues to drive, if the vehicle speed decreases and is lower than the speed threshold, the controller 1328 controls the driving member 1322 to reverse, driving the link 1323 to actuate. The actuation of the link causes the airfoil 1321 to rotate around the rotation shaft 1325, bringing the airfoil 1321 into the folded state, thereby reducing the wind resistance of the motorcycle 100. In some embodiments, the speed threshold is greater than or equal to 60 km and less than or equal to 100 km.

[0041] In some embodiments, the driving member 1322 can be a motor. For example, the motor can be a DC brushed motor and a DC brushless motor. In some embodiments, the motor is a worm gear motor, and the worm gear is self-locking to prevent stall and damage to the internal motor. Optionally, a Hall angle sensor is provided inside the motor to collect the rotation angle of the motor and send it to the controller 1328.

[0042] In some embodiments, the motorcycle 100 includes a detection component 14 for detecting the vehicle speed of the motorcycle. The detection component 14 is selected from at least one of the following: wheel speed sensor, body control module (BCM), engine electronic control module (ECM), microcontroller (MCU), anti-lock braking system (ABS) of an automobile, or vehicle stability control (MSC).

[0043] Such as Figure 6As shown, in some embodiments, the detection component 14 sends vehicle speed signals, wheel speed signals, wheel speed pulse signals, etc. to the CAN bus. The CAN bus communicates with the electronic control unit 15, and the electronic control unit 15 transmits the vehicle speed information to the controller 1328. Specifically, in a motorcycle equipped with an anti-lock braking system (ABS), the vehicle speed signal, wheel speed signal, and wheel speed pulse signal are all sent to the bus by the anti-lock braking system (ABS). In a motorcycle equipped with a motorcycle stability control (MSC) system, the vehicle speed signal, wheel speed signal, and wheel speed pulse signal are all sent to the bus by the MSC. In a motorcycle that is not equipped with an anti-lock braking system (ABS) for automobiles nor an electronic control module (ECM), if a wheel speed sensor is equipped, the body control module (BCM) collects the wheel speed signal and sends the vehicle speed signal, wheel speed signal, and wheel speed pulse signal to the bus. If a wheel speed sensor is not equipped, for a fuel-driven motorcycle, the vehicle speed signal is sent to the bus by the engine control module (ECM), and for an electric-driven motorcycle, the vehicle speed signal is sent to the bus by the microcontroller (MCU).

[0044] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
