Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to an electric motorcycle. Background Technology

[0002] In general, electric motorcycles primarily rely on water cooling or fans for heat dissipation. When the power output of an electric motorcycle is relatively low, these existing methods are sufficient. However, when the power output of an electric motorcycle is high, it generates significantly more heat. In this case, water cooling or fan-based cooling becomes less efficient and cannot meet the cooling requirements of high-powered electric motorcycles. Summary of the Invention

[0003] To address the issue that while conventional electric motorcycles primarily rely on water cooling or fans for heat dissipation, these methods are inefficient and cannot meet the cooling demands of high-powered motorcycles, this invention provides an electric motorcycle that utilizes an air intake assembly. This assembly allows external air to enter the motorcycle during operation, passing through the radiator, motor controller, and motor, thereby enhancing the motorcycle's cooling performance through airflow.

[0004] To achieve the above objectives, the present invention provides an electric motorcycle, comprising: a frame; a body panel having a receiving space and at least partially disposed on the frame; a wheel assembly including a front wheel and a rear wheel; a suspension assembly including a front suspension and a rear suspension, the front suspension being connected to the front side of the frame and the front wheel being connected to the front suspension, the rear suspension being connected to the rear side of the frame and the rear wheel being connected to the rear suspension; a power assembly including a motor for driving the front wheel and / or the rear wheel; a saddle assembly including a saddle; a control system at least partially disposed within the receiving space; a power supply device for providing electrical energy; the electric motorcycle further comprising an air intake assembly; the air intake assembly including: an air intake duct extending substantially along the longitudinal direction of the electric motorcycle to allow air to enter the air intake assembly; an air inlet disposed on the front side of the air intake duct and communicating with the air intake duct; and a first air outlet disposed on the rear side of the air intake duct for discharging air from the air intake assembly.

[0005] Furthermore, the air intake assembly also includes several air intake ramps, which are located at the air intake.

[0006] Furthermore, the electric motorcycle includes a first projection plane perpendicular to the vertical direction and a second projection plane perpendicular to the horizontal direction. The air intake slope is substantially perpendicular to the second projection plane. The air intake slope has a first projection line in the second projection plane along the horizontal direction. The first projection plane has a second projection line in the second projection plane along the horizontal direction. The angle between the first projection line and the second projection line is greater than or equal to 30° and less than or equal to 50°. Furthermore, along the vertical direction, the slope of several air intake slopes gradually decreases from top to bottom.

[0007] Furthermore, the air intake assembly also includes a second air outlet, which is disposed between the first air outlet and the air intake and located on the lower side of the air intake assembly.

[0008] Furthermore, the second air outlet is located at the lowest point of the air inlet assembly.

[0009] Furthermore, the air inlet includes several air inlet holes, each with an air inlet ramp.

[0010] Furthermore, a hole wall is provided between adjacent air inlets, and adjacent air inlets are separated by the hole wall.

[0011] Furthermore, the air intake assembly also includes a first side plate, a second side plate, and a bottom plate.

[0021] 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.

[0022] like Figure 1 As shown, an electric motorcycle 100 includes a frame 11, a body panel 12, a wheel assembly 13, a suspension assembly 14, a saddle assembly 15, and a lighting assembly 16. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The front, rear, left, right, upper, and lower sides are shown. The frame 11 extends substantially in the longitudinal direction, and the body panel 12 forms a receiving space and is at least partially mounted on the frame 11. A wheel assembly 13 is located below the frame 11 and is connected to a suspension assembly 14, which is mounted to the frame 11. The wheel assembly 13 includes a front wheel 131 and a rear wheel 132. In the illustrative embodiment, the front wheel 131 serves as the steering driven wheel of the electric motorcycle 100, and the rear wheel 132 serves as the drive wheel of the electric motorcycle 100. The suspension assembly 14 includes a front suspension 141 and a rear suspension 142. The front suspension 141 is mounted on the front side of the frame 11, and the front wheel 131 is mounted on the front suspension 141. The rear suspension 142 is mounted on the rear side of the frame 11, and the rear wheel 132 is mounted on the rear suspension 142. The saddle assembly 15 includes a saddle 151 and a seat 152. The saddle 151 is mounted on the frame 11 and is for the driver to sit on. The saddle 151 and the saddle cover 152 are rotatably connected. The lighting assembly 16 is partially mounted on the frame 11 and is used to provide illumination and warning functions.

[0023] like Figures 2 to 4As shown, in one implementation, the electric motorcycle 100 also includes a control system 18, a cooling assembly 19, an air intake assembly 24, and a power assembly 20. The power assembly 20 includes a motor 201, which drives the rear wheel 132 to rotate, thus propelling the electric motorcycle 100. The cooling assembly 19 includes a radiator 191 and a water pump 192 for cooling the electric motorcycle 100. The control system 18 includes a motor controller 181, which receives and issues commands to control the motor 201. The air intake assembly 24 is located on the underside of the electric motorcycle 100, connected to the frame 11 and the body panel 12. The air intake assembly 24 extends substantially along the longitudinal direction of the electric motorcycle 100 and is used to cool the radiator 191, the motor controller 181, the water pump 192, and the motor 201. The air intake assembly 24 essentially covers the lower side of the electric motorcycle 100. The air intake assembly 24 forms an air intake duct 241, which extends substantially along the front-to-back direction of the electric motorcycle 100. This facilitates air cooling of the radiator 191, motor controller 181, water pump 192, and motor 201, improving the heat dissipation effect of the electric motorcycle 100 and thus extending its service life. The air intake duct 241 refers to the flow path through which air enters and exits the air intake assembly 24 during the operation of the electric motorcycle 100.

[0024] like Figures 2 to 4As shown, specifically, the air intake assembly 24 includes an air inlet 242, a second air outlet 243, and a first air outlet 244. Along the longitudinal direction of the electric motorcycle 100, the air inlet 242 is located on the front side of the body panel 12 and communicates with the air intake duct 241. It allows air to enter the air intake assembly 24 during the operation of the electric motorcycle 100, thereby cooling the radiator 191, motor controller 181, water pump 192, and motor 201 through air cooling. This improves the heat dissipation effect of the electric motorcycle 100 and thus extends its service life. Along the longitudinal direction of the electric motorcycle 100, the first air outlet 244 is located near the motor 201 and is used to exhaust air from the air intake assembly 24. Along the longitudinal and vertical directions of the electric motorcycle 100, the second air outlet 243 is located between the air inlet 242 and the first air outlet 244. Specifically, the second air outlet 243 is located behind the air inlet 242 and in front of the first air outlet 244, and is located below the motor controller 181. The air inlet 242 opens forward, the second air outlet 243 opens downward, and the first air outlet 244 opens downward and faces backward. This arrangement allows for better airflow into the air inlet 242 during operation, enabling the air to carry away heat from the radiator 191, motor controller 181, water pump 192, and motor 201. This heat is then expelled from the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, improving the cooling effect of the electric motorcycle 100. In addition, during the operation of the electric motorcycle 100, mud and water may enter the air intake component 24 from the air intake 242. By setting the opening of the second air outlet 243 downward, the mud and water can be discharged from the second air outlet 243, thereby effectively preventing the mud and water from contaminating and clogging the air intake component 24. This helps to improve the air intake effect of the air intake component 24, thereby improving the heat dissipation effect and service life of the electric motorcycle 100.

[0025] In this embodiment, the opening of the first air outlet 244 faces rearward and is positioned towards the motor 201, thereby improving the cooling effect of the motor 201. The opening of the second air outlet 243 is smaller than that of the first air outlet 244. This reduces the amount of air entering through the second air outlet 243, allowing more air to be delivered to the first air outlet 244, thus improving the cooling effect of the motor controller 181, water pump 192, and motor 201. Specifically, along the front-rear direction of the electric motorcycle 100, the motor controller 181 is positioned in front of the motor 201, and the water pump 192 is positioned behind the motor controller 181 and in front of the motor 201. The opening of the second air outlet 243 is smaller than that of the first air outlet 244, which allows air to be better delivered to the water pump 192 and the motor 201 located behind the motor controller 181, thereby improving the heat dissipation effect of the water pump 192 and the motor 201, and thus improving the heat dissipation effect and service life of the electric motorcycle 100.

[0026] In this embodiment, along the vertical direction of the electric motorcycle 100, the second air outlet 243 is located at the lowest point of the body cover 12, which allows mud and water to flow out of the air intake component 24 better, effectively preventing mud and water from contaminating and clogging the air intake component 24, which is beneficial to improving the air intake effect of the air intake component 24, thereby improving the heat dissipation effect and service life of the electric motorcycle 100.

[0027] like Figures 3 to 4 As shown, in one implementation, the electric motorcycle 100 includes a first projection plane 101 perpendicular to the vertical direction and a second projection plane 102 perpendicular to the horizontal direction, with the second projection plane 102 perpendicular to the first projection plane 101. Specifically, the air intake duct 241 is arranged substantially parallel to the first projection plane 101.

[0028] As one implementation, the air inlet 242 is provided with several air intake ramps 245. These ramps 245 are distributed along the vertical and horizontal directions of the electric motorcycle 100. The air intake ramps 245 prevent some mud and water from entering the air intake assembly 24, effectively preventing contamination and blockage, thus improving the air intake effect and consequently enhancing the heat dissipation and lifespan of the electric motorcycle 100. Specifically, the air intake ramps 245 are substantially perpendicular to the second projection plane 102. Along the horizontal direction of the electric motorcycle 100, the projection of the air intake ramps 245 onto the second projection plane 102 is the first projection line, and the projection of the first projection plane 101 onto the second projection plane 102 is the second projection line. The acute angle φ formed by the first and second projection lines is greater than or equal to 30° and less than or equal to 50°. At this time, the air intake slope 245 can effectively prevent some mud and water from entering the air intake component 24, thereby effectively preventing mud and water from contaminating and clogging the air intake component 24, which is conducive to improving the air intake effect of the air intake component 24, and thus improving the heat dissipation effect and service life of the electric motorcycle 100.

[0029] In this embodiment, along the vertical direction of the electric motorcycle 100, the acute angle between the first projection line and the second projection line gradually decreases from top to bottom; that is, the slope of the upper air intake slope 245 is greater than the slope of the lower air intake slope 245. Specifically, along the vertical direction of the electric motorcycle 100, the slope of several air intake slopes 245 gradually decreases from top to bottom. Furthermore, since the trajectory of mud and water entering the air intake assembly 24 is essentially parabolic, the above arrangement effectively prevents mud and water from entering the air intake assembly 24, thereby improving the air intake effect of the air intake assembly 24, and enhancing the heat dissipation effect and service life of the electric motorcycle 100.

[0030] As one implementation method, the air intake assembly 24 and the frame 11 can be fixedly connected by bolts or other means, and the air intake assembly 24 and the body panel 12 can be fixedly connected by bolts or clips or other means, thereby achieving a stable connection between the air intake assembly 24 and the frame 11, and a stable connection between the air intake assembly 24 and the body panel 12, improving the air intake effect of the air intake assembly 24 during the operation of the electric motorcycle 100, and thus improving the heat dissipation effect and service life of the electric motorcycle 100.

[0031] In one implementation, the air intake assembly 24 also includes a first side plate 246, a second side plate, and a bottom plate 248. The first side plate 246 is located on the left side of the electric motorcycle 100, the second side plate is located on the right side of the electric motorcycle 100, and the bottom plate 248 is located on the lower side of the electric motorcycle. One side of the bottom plate 248 is connected to the first side plate 246, and the other side of the bottom plate 248 is connected to the second side plate. The first side plate 246, the second side plate, and the bottom plate 248 together constitute the air intake duct 241. The first side plate 246, the second side plate, and the bottom plate 248 can be integrally formed, thereby improving the sealing performance of the air intake assembly 24, enhancing the air intake effect of the air intake assembly 24 during the operation of the electric motorcycle 100, and improving the heat dissipation effect and service life of the electric motorcycle 100. The first side plate 246, the second side plate, and the bottom plate 248 can also be fixedly connected, facilitating the processing of the air intake assembly 24 and making it easy to replace the air intake assembly 24.

[0032] As one implementation, the air inlet 242 includes several air inlet holes 2421, with a hole wall between adjacent air inlet holes 2421. The adjacent air inlet holes 2421 are separated by the hole walls, facilitating airflow into the air intake assembly 24 through the air inlet holes 2421 during the operation of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the openings of the air inlet holes 2421 are arranged facing forward along the front-rear direction of the electric motorcycle 100. Through this arrangement, during the operation of the electric motorcycle 100, air can be better channeled into the air intake assembly 24 through the air inlet holes 2421, allowing the air to carry away heat from the radiator 191, motor controller 181, water pump 192, and motor 201. This heat is then discharged from the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the air inlet 2421 can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that as long as the amount of air entering the air intake assembly 24 is sufficient, there is no need to change the external structure of the electric motorcycle 100, thereby improving the space utilization and resource utilization of the electric motorcycle 100.

[0033] In this embodiment, each air inlet 2421 is provided with an air inlet ramp 245. The air inlet ramp 245 provides a buffer when air enters the air inlet 2421, thereby reducing the resistance of the air intake assembly 24 during the operation of the electric motorcycle 100 and increasing the speed of the electric motorcycle 100. In addition, the air inlet ramp 245 can effectively prevent some mud and water from entering the air intake assembly 24 through the air inlet 2421, thereby effectively preventing contamination and blockage of the air intake assembly 24, which is beneficial to improving the air intake effect of the air intake assembly 24, and thus improving the heat dissipation effect and service life of the electric motorcycle 100.

[0034] Specifically, along the vertical direction of the electric motorcycle 100, from top to bottom, the acute angle between the first projection line and the second projection line gradually decreases. That is, the slope of the air intake slope 245 of the upper air intake 2421 is greater than that of the lower air intake slope 245. Since the trajectory of mud and water entering the air intake component 24 is basically parabolic, the above-mentioned arrangement can effectively block mud and water from entering the air intake component 24, thereby improving the air intake effect of the air intake component 24, improving the heat dissipation effect and service life of the electric motorcycle 100.

[0035] As one implementation, the electric motorcycle 100 has a first air inlet on its left side and a second air inlet on its right side, allowing air to enter the air intake assembly 24 through the first and second air inlets during operation. This arrangement increases the airflow, thereby cooling the radiator 191, motor controller 181, water pump 192, and motor 201 through air cooling, improving the heat dissipation effect of the electric motorcycle 100 and extending its service life.

[0036] In this embodiment, the first air inlet includes a plurality of first air inlet holes, with hole walls provided between adjacent first air inlet holes and spaced apart by the hole walls. This facilitates air entering the air intake assembly 24 through the plurality of first air inlet holes during the operation of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the openings of the first air inlets are arranged facing forward along the front-rear direction of the electric motorcycle 100. With the above arrangement, during the operation of the electric motorcycle 100, air can be better allowed to enter the air intake assembly 24 through the first air inlets, thereby allowing the air to carry away the heat from the radiator 191, motor controller 181, water pump 192, and motor 201, and then the heat is discharged from the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, thus improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the first air inlet can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that as long as the amount of air entering the air intake assembly 24 is sufficient, there is no need to change the external structure of the electric motorcycle 100, thereby improving the space utilization and resource utilization of the electric motorcycle 100.

[0037] Specifically, each first air inlet is equipped with a first air inlet ramp. The first air inlet ramp provides a buffer when air enters the first air inlet, thereby reducing the resistance of the air intake assembly 24 during the operation of the electric motorcycle 100 and increasing the speed of the electric motorcycle 100. In addition, the first air inlet ramp can effectively prevent some mud and water from entering the air intake assembly 24 through the first air inlet, thereby effectively preventing contamination and blockage of the air intake assembly 24 by mud and water, which is conducive to improving the air intake effect of the air intake assembly 24, and thus improving the heat dissipation effect and service life of the electric motorcycle 100.

[0038] In this embodiment, the second air inlet includes a plurality of second air inlets, with a wall between adjacent second air inlets and spaced apart by the wall. This facilitates airflow into the air intake assembly 24 through the plurality of second air inlets during the operation of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the openings of the second air inlets face forward along the front-rear direction of the electric motorcycle 100. With the above arrangement, during the operation of the electric motorcycle 100, air can be better introduced into the air intake assembly 24 through the second air inlets, thereby carrying away the heat from the radiator 191, motor controller 181, water pump 192, and motor 201, and then expelling the heat from the electric motorcycle 100 through the first air outlet 244, thus improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the second air inlet can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that as long as the amount of air entering the air intake assembly 24 is sufficient, there is no need to change the external structure of the electric motorcycle 100, thereby improving the space utilization and resource utilization of the electric motorcycle 100.

[0039] Specifically, each second air intake is equipped with a second air intake ramp. This ramp provides a buffer as air enters the second air intake, reducing resistance in the air intake assembly 24 during the electric motorcycle 100's operation and increasing its speed. Furthermore, the ramp effectively prevents mud and water from entering the air intake assembly 24 through the second air intake, thus preventing contamination and blockage. This improves the air intake efficiency of the air intake assembly 24, thereby enhancing the heat dissipation and lifespan of the electric motorcycle 100.

[0040] like Figure 5As shown, in one implementation, the electric motorcycle 100 also includes a footrest assembly 25 and a steering assembly 26. The steering assembly 26 is connected to the suspension assembly 14 and is mounted on the frame 11, used to control the direction of movement of the electric motorcycle 100. Specifically, the steering assembly 26 is connected to the front suspension 141, thereby controlling the steering of the front wheel 131 through the front suspension 141, and thus controlling the direction of movement of the electric motorcycle 100. The footrest assembly 25 is at least partially mounted on the frame 11, used to place the rider's feet and provide support for the rider's feet. Specifically, the footrest assembly 25 is connected to the frame 11 by bolts or other fixing methods, thereby achieving a stable connection between the footrest assembly 25 and the frame 11. In this embodiment, the footrest assembly 25 is at least partially disposed between the steering assembly 26 and the saddle assembly 15, and the footrest assembly 25 extends substantially along the longitudinal direction of the electric motorcycle 100.

[0041] In one implementation, within a first projection plane 101 perpendicular to the vertical direction of the electric motorcycle 100, the centerline of the front wheel 131 has a first projection line along the vertical direction within the first projection plane 101, and the centerline of the rear wheel 132 has a second projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101; the front end of the pedal assembly 25 has a third projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101; and the rear end of the pedal assembly 25 has a fourth projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101. The pedal assembly 25 is positioned substantially parallel to the first projection plane 101.

[0042] Along the longitudinal direction of the electric motorcycle 100, the distance between the first projection line and the second projection line is the first distance D1, and the distance between the third projection line and the fourth projection line is the second distance D2. The ratio of the first distance D1 to the second distance D2 is greater than or equal to 4.4 and less than or equal to 6.7. Here, the first distance D1 is the shortest distance between the first and second projection lines, and the second distance D2 is the shortest distance between the third and fourth projection lines. Within this distance range, the footrest assembly 25 can provide more comfortable support for the rider's feet, thereby improving the riding comfort of the electric motorcycle 100 and thus enhancing its human-machine interface. Furthermore, while providing comfortable support for the rider's feet, the electric motorcycle 100 has a more compact structure, improving its overall compactness and thus giving it better maneuverability during riding, improving the rider's handling.

[0043] In this embodiment, the ratio of the first distance D1 to the second distance D2 is greater than or equal to 5 and less than or equal to 6. When the ratio of the first distance D1 to the second distance D2 is greater than or equal to 5 and less than or equal to 6, the foot pedal assembly 25 can provide more comfortable support for the rider's feet, thereby improving the riding comfort of the electric motorcycle 100 and thus improving the human-machine interface of the electric motorcycle 100. Furthermore, while providing comfortable support for the rider's feet, the structure of the electric motorcycle 100 is more compact, improving the overall compactness of the electric motorcycle 100, thereby giving the electric motorcycle 100 better maneuverability during riding and improving the rider's handling.

[0044] In this embodiment, the ratio of the first distance D1 to the second distance D2 is 5.4. When the ratio of the first distance D1 to the second distance D2 is 5.4, the footrest assembly 25 can provide more comfortable support for the rider's feet, thereby improving the riding comfort of the electric motorcycle 100 and thus improving the human-machine interface of the electric motorcycle 100. Furthermore, while providing comfortable support for the rider's feet, the structure of the electric motorcycle 100 is more compact, improving the overall compactness of the electric motorcycle 100, thus giving the electric motorcycle 100 better maneuverability during riding and improving the rider's handling.

[0045] As one implementation, the electric motorcycle 100 also includes a saddle assembly 15, which includes a saddle 151 and a saddle cover 152, rotatably connected. A seating point 1521 is provided on the saddle cover 152. The seating point 1521 refers to the point where the rider sits on the saddle cover 152. The steering assembly 26 includes a grip mechanism 261, which can be a steering handlebar 2611, located on both sides of the electric motorcycle 100. The steering handlebar 2611 is essentially cylindrical. When the electric motorcycle 100 is traveling straight, the steering handlebar 2611 is in a balanced state, extending substantially along the left-right direction of the electric motorcycle 100. Along the vertical direction of the electric motorcycle 100, the projection of the axis of the steering handlebar 2611 onto the first projection plane 101 is the fifth projection line, and the projection of the seating point 1521 onto the first projection plane 101 is the first projection point. Along the longitudinal direction of the electric motorcycle 100, the distance between the fifth projection line and the first projection line is the third distance D3, and the shortest distance between the first projection point and the first projection line is the fourth distance D4. The third distance D3 is the shortest distance between the fifth projection line and the first projection line.

[0046] Specifically, the ratio of the first distance D1 to the third distance D3 is greater than or equal to 2.4 and less than or equal to 3.7. In this case, the steering assembly 26 can provide a more comfortable grip for the rider's hands, thereby improving the driving comfort of the electric motorcycle 100 and thus enhancing its human-machine interface. The ratio of the first distance D1 to the fourth distance D4 is greater than or equal to 1.2 and less than or equal to 1.9. In this case, the saddle assembly 15 can provide more comfortable support for the rider, thereby improving the driving comfort of the electric motorcycle 100 and thus enhancing its human-machine interface.

[0047] Specifically, the ratio of the first distance D1 to the third distance D3 is greater than or equal to 2.8 and less than or equal to 3.3. In this case, the steering assembly 26 can provide a more comfortable grip for the rider's hands, thereby improving the driving comfort of the electric motorcycle 100 and consequently enhancing its human-machine interface. The ratio of the first distance D1 to the fourth distance D4 is greater than or equal to 1.4 and less than or equal to 1.7. In this case, the saddle assembly 15 can provide more comfortable support for the rider, thereby improving the driving comfort of the electric motorcycle 100 and consequently enhancing its human-machine interface.

[0048] In this embodiment, the ratio of the first distance D1 to the third distance D3 is 3. At this time, the steering assembly 26 can provide a more comfortable grip for the rider's hands, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing its human-machine interface. The ratio of the first distance D1 to the fourth distance D4 is 1.5. At this time, the saddle assembly 15 can provide more comfortable support for the rider, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing its human-machine interface.

[0049] Specifically, when the ratio of the first distance D1 to the third distance D3 is 3 and the ratio of the first distance D1 to the fourth distance D4 is 1.5, the structure of the electric motorcycle 100 is more stable and compact, thereby improving the overall stability and compactness of the electric motorcycle 100, and thus improving the service life and driving operability of the electric motorcycle 100.

[0050] As one implementation, a foot protector 121 is provided on the side of the body panel 12 near the rider's feet, and the foot protector 121 extends substantially along the vertical direction of the electric motorcycle. Along the front-rear direction of the electric motorcycle 100, the front side of the saddle assembly 15, the rear side of the foot protector, and the upper side of the foot pedal assembly 25 together form the receiving space 27.

[0051] Along the left-right direction of the electric motorcycle 100, within a second projection plane 102 perpendicular to the left-right direction of the electric motorcycle 100, the accommodating space 27 serves as a first projection surface on the second projection plane 102. The area of ​​the first projection surface is greater than or equal to 0.09 square meters and less than or equal to 0.13 square meters. When the area of ​​the first projection surface is greater than or equal to 0.09 square meters and less than or equal to 0.13 square meters, the accommodating space 27 can provide a more comfortable place for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100.

[0052] Specifically, the area of ​​the first projection surface is greater than or equal to 0.1 square meters and less than or equal to 0.12 square meters. When the area of ​​the first projection surface is greater than or equal to 0.1 square meters and less than or equal to 0.12 square meters, the accommodating space 27 can provide a more comfortable place for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and thus improving the human-machine interaction of the electric motorcycle 100.

[0053] In this embodiment, the area of ​​the first projection surface is 0.11 square meters. At this time, the accommodating space 27 can provide a more comfortable place for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing its human-machine interface. Furthermore, when the area of ​​the fifth projection surface is 0.11 square meters, while still providing a comfortable place for the driver's feet, the structure of the electric motorcycle 100 is more compact, improving its overall compactness and thus giving it better maneuverability during operation, enhancing the driver's handling.

[0054] like Figure 6As shown, in one implementation, the electric motorcycle 100 also includes a power supply unit 17, a control system 18, and a power assembly 20. The power assembly 20 includes a motor 201, which drives the rear wheel 132 to rotate, thus propelling the electric motorcycle 100. The motor 201 has a first rotating shaft 2011, which extends substantially along the left-right direction of the electric motorcycle 100. The motor 201's operation drives the first rotating shaft 2011 to rotate. The control system 18 includes a motor controller 181, which receives and issues commands to control the motor 201. The motor controller 181 can be mounted on the frame 11. The frame 11 forms a first space located below the footrest assembly 25. The first space limits the motor controller 181, improving its assembly stability. Specifically, along the vertical direction of the electric motorcycle 100, the motor controller 181 is located below the footrest assembly 25, and is enclosed by the first space, the footrest assembly 25, and the air intake assembly 24, thereby ensuring the stability of the motor controller 181 and enabling it to better control the motor 201. The power supply device 17 includes an energy storage element 171, which is mounted on the frame 11 and located in the saddle 151, and is used to provide power to the electric motorcycle 100.

[0055] In this embodiment, within a first projection plane 101 perpendicular to the vertical direction of the electric motorcycle 100, the axis of the motor 201 has a sixth projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101; that is, the axis of the first rotating shaft 2011 has a sixth projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101. The energy storage element 171 has a first symmetry plane 103 extending along the left-right direction of the electric motorcycle 100, and the first symmetry plane 103 has a seventh projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101. The axis of the rear wheel 132 has an eighth projection line along the vertical direction of the electric motorcycle 100 within the first projection plane 101. Along the front-rear direction of the electric motorcycle 100, the distance between the sixth and eighth projection lines is L1, and the distance between the seventh and eighth projection lines is L2. The distance L1 is greater than or equal to 350 mm and less than or equal to 430 mm.

[0056] As one implementation method, the difference between L2 and L1 is greater than 0 mm and less than or equal to 600 mm. In this case, since the energy storage element 171 and the motor 201 in the electric motorcycle 100 are relatively heavy, the above arrangement allows for a reasonable arrangement of their positions, ensuring they are positioned along the longitudinal direction of the electric motorcycle 100. This helps maintain a relatively stable state for the electric motorcycle 100, improving its stability and balance, and thus enhancing driving safety when stationary or in motion. Specifically, along the longitudinal direction of the electric motorcycle 100, the motor 201 can be positioned either in front of or behind the energy storage element 171.

[0057] In this embodiment, the difference between L2 and L1 is greater than or equal to 220mm and less than or equal to 500mm. Since the energy storage element 171 and the motor 201 in the electric motorcycle 100 are relatively heavy, the above arrangement allows for a reasonable arrangement of their positions, ensuring they are positioned along the front-rear direction of the electric motorcycle 100. This maintains a relatively stable state for the electric motorcycle 100, improving its stability and balance, and thus enhancing driving safety when the electric motorcycle 100 is stationary or in motion.

[0058] In one implementation, the motor controller 181 has a second symmetry plane 104 extending along the left-right direction of the electric motorcycle 100. The second symmetry plane 104 has a ninth projection line within the first projection plane 101 along the up-down direction of the electric motorcycle 100. The distance between the ninth projection line and the eighth projection line along the front-rear direction of the electric motorcycle 100 is L3. The difference between L3 and L1 is greater than or equal to 270 mm and less than or equal to 510 mm. Since the motor controller 181 and the motor 201 in the electric motorcycle 100 are relatively heavy, the above arrangement allows for a reasonable arrangement of their positions, ensuring they are positioned along the front-rear direction of the electric motorcycle 100. This maintains a relatively stable state for the electric motorcycle 100, improving its stability and balance, and thus enhancing driving safety when the electric motorcycle 100 is stationary or in motion. Specifically, along the front-rear direction of the electric motorcycle 100, the motor controller 181 is located in front of the motor 201.

[0059] In this embodiment, the difference between L3 and L1 is greater than or equal to 330mm and less than or equal to 450mm. Since the motor controller 181 and motor 201 in the electric motorcycle 100 are relatively heavy, the above arrangement allows for a reasonable arrangement of their positions, ensuring they are positioned along the front-rear direction of the electric motorcycle 100. This maintains a relatively stable state for the electric motorcycle 100, improving its stability and balance, and thus enhancing driving safety when the electric motorcycle 100 is stationary or in motion.

[0060] As one implementation, the difference between L3 and L2 is greater than or equal to 260mm and less than or equal to 320mm. In this case, since the motor controller 181 and the energy storage element 171 in the electric motorcycle 100 are relatively heavy, the above arrangement allows for a reasonable arrangement of the positions of the motor controller 181 and the motor 201, ensuring that the motor controller 181 and the energy storage element 171 are positioned along the front-rear direction of the electric motorcycle 100. This maintains a relatively stable state for the electric motorcycle 100, improving its stability and balance, and thus enhancing driving safety when the electric motorcycle 100 is stationary or in motion. Specifically, along the front-rear direction of the electric motorcycle 100, the motor controller 181 is located in front of the energy storage element 171.

[0061] In this embodiment, the difference between L3 and L2 is greater than or equal to 270mm and less than or equal to 310mm. Since the motor controller 181 and the energy storage element 171 in the electric motorcycle 100 are relatively heavy, the above arrangement allows for a reasonable arrangement of the positions of the motor controller 181 and the motor 201, ensuring that the motor controller 181 and the energy storage element 171 are arranged along the front-rear direction of the electric motorcycle 100. This maintains a relatively stable state for the electric motorcycle 100, improving its stability and balance, and thus ensuring stability when the electric motorcycle 100 is stationary or in motion, thereby enhancing driving safety.

[0062] like Figure 6 As shown, in one implementation, the saddle 151 forms a second receiving space 1511, and the power supply device 17 is at least partially disposed within the second receiving space 1511. Specifically, the energy storage element 171 is at least partially disposed within the second receiving space 1511, thereby limiting and fixing the energy storage element 171 through the second receiving space 1511, effectively preventing damage to the body or wiring due to unstable installation of the energy storage element 171. In this embodiment, the volume of the second receiving space 1511 is greater than or equal to 0.01 m³. 3 And less than or equal to 0.014m 3At this time, the rated power of motor 201 is greater than or equal to 5 kW and less than or equal to 12.5 kW, and the ratio of the rated power of motor 201 to the volume of the second accommodating space 1511 is greater than or equal to 357 kW / m³. 3 And less than or equal to 1250kw / m 3 By using the above configuration, the size of the energy storage element 171 can be controlled by adjusting the size of the space accommodating it. The volume of the energy storage element 171 is approximately the same as the volume of the second accommodating space 1511. In this case, with a fixed volume and a fixed amount of energy stored in the energy storage element 171, a smaller energy storage element 171 can provide the motor 201 with a larger power output, improving energy utilization and reducing resource waste.

[0063] Specifically, the volume of the second accommodating space 1511 is greater than or equal to 0.011m³. 3 And less than or equal to 0.013m 3 At this time, the rated power of motor 201 is greater than or equal to 7 kW and less than or equal to 10 kW, and the ratio of the rated power of motor 201 to the volume of the second accommodating space 1511 is greater than or equal to 538 kW / m². 3 And less than or equal to 910 kW / m 3 By using the above configuration, the size of the energy storage element 171 can be controlled by adjusting the size of the space accommodating it. The volume of the energy storage element 171 is approximately the same as the volume of the second accommodating space 1511. In this case, with a fixed volume and a fixed amount of energy stored in the energy storage element 171, a smaller energy storage element 171 can provide the motor 201 with a larger power output, improving energy utilization and reducing resource waste.

[0064] In this embodiment, the volume of the second accommodating space 1511 is 0.012 m³. 3 At this time, the rated power of motor 201 is 12.5 kW, and the ratio of the rated power of motor 201 to the volume of the second accommodating space 1511 is 1042 kW / m². 3 By using the above configuration, the size of the energy storage element 171 can be controlled by adjusting the size of the space accommodating it. The volume of the energy storage element 171 is approximately the same as the volume of the second accommodating space 1511. In this case, with a fixed volume and a fixed amount of energy stored in the energy storage element 171, a smaller energy storage element 171 can provide the motor 201 with a larger power output, improving energy utilization and reducing resource waste.

[0065] As one implementation method, the ratio of the rated power of the motor 201 to the volume of the second accommodating space 1511 is greater than or equal to 357 kW / m².3 And less than or equal to 1250kw / m 3 At this time, the rotational speed of motor 201 is greater than or equal to 4800 r / min and less than or equal to 10000 r / min. That is, when the ratio of the rated power of motor 201 to the volume of energy storage element 171 is greater than or equal to 357 and less than or equal to 1250, the rotational speed of motor 201 is greater than or equal to 4800 r / min and less than or equal to 10000 r / min. Through this setting, the energy storage element 171, with its relatively small energy storage capacity, can provide a larger power to motor 201, thereby enabling motor 201 to achieve a higher rotational speed. This, in turn, drives the rear wheel 132 to travel at a higher speed, improving the structural compactness of the electric motorcycle 100 and enhancing its maneuverability, thus providing the driver with a better driving experience.

[0066] As one implementation method, when the ratio of the rated power of the motor 201 to the volume of the second accommodating space 1511 is greater than or equal to 538 kW / m² 3 And less than or equal to 910 kW / m 3 At that time, the rated power of motor 201 is greater than or equal to 7 kW and less than or equal to 10 kW, and the volume of the second accommodating space 1511 is greater than or equal to 0.011 m³. 3 And less than or equal to 0.013m 3 At that time, the speed of motor 201 is greater than or equal to 4800 r / min and less than or equal to 10000 r / min. That is, when the ratio of the rated power of motor 201 to the volume of energy storage element 171 is greater than or equal to 538 kW / m³. 3 And less than or equal to 910 kW / m 3 At this time, the rotational speed of motor 201 is greater than or equal to 4800 r / min and less than or equal to 10000 r / min. Through the above settings, the energy storage element 171 with a smaller energy storage capacity can provide a larger power to motor 201, thereby enabling motor 201 to achieve a larger rotational speed, which in turn drives the rear wheel 132 to travel at a higher speed, improving the structural compactness of electric motorcycle 100 and enhancing the driving operability of electric motorcycle, giving the driver a better driving experience.

[0067] As one implementation method, the ratio of the rated power of the motor 201 to the volume of the second accommodating space 1511 is greater than or equal to 357 kW / m². 3 And less than or equal to 1250kw / m 3 At that time, the speed of motor 201 is greater than or equal to 6800 r / min and less than or equal to 8000 r / min. That is, the ratio of the rated power of motor 201 to the volume of energy storage element 171 is greater than or equal to 357 kW / m³. 3 And less than or equal to 1250kw / m 3At this time, the rotational speed of motor 201 is greater than or equal to 6800 r / min and less than or equal to 8000 r / min. Through the above settings, the energy storage element 171 with a smaller energy storage capacity can provide a larger power to motor 201, thereby enabling motor 201 to achieve a larger rotational speed, which in turn drives the rear wheel 132 to travel at a higher speed, improving the structural compactness of electric motorcycle 100 and enhancing the driving operability of electric motorcycle, giving the driver a better driving experience.

[0068] As one implementation method, when the ratio of the rated power of the motor 201 to the volume of the second accommodating space 1511 is greater than or equal to 538 kW / m² 3 And less than or equal to 910 kW / m 3 At that time, the rated power of motor 201 is greater than or equal to 7 kW and less than or equal to 10 kW, and the volume of the second accommodating space 1511 is greater than or equal to 0.011 m³. 3 And less than or equal to 0.013m 3 At that time, the speed of motor 201 is greater than or equal to 6800 r / min and less than or equal to 8000 r / min.

[0069] As one implementation method, the ratio of the rated power of the motor 201 to the volume of the second accommodating space 1511 is 1042 kW / m². 3 At that time, the rated power of motor 201 is 12.5 kW and the volume of the second accommodating space 1511 is 0.012 m³. 3At this time, the rotational speed of motor 201 is 10000 r / min. Through the above configuration, the second accommodating space 1511 can meet the installation requirements of the energy storage element 171 while also satisfying the overall layout requirements of the electric motorcycle 100, reducing the resistance of the electric motorcycle 100 during operation and thus increasing its speed. Furthermore, the energy storage element 171, with its smaller capacity, can provide greater power to motor 201, allowing motor 201 to achieve a higher rotational speed, thereby driving the rear wheel 132 at a higher speed. This improves the structural compactness of the electric motorcycle 100 and enhances its maneuverability, providing the driver with a better driving experience.
