[0022] 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.

[0023] 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 1The front side, the rear side, the left side, the right side, the upper side and the lower side are shown. Among them, the frame 11 extends substantially in the front-rear direction, and the vehicle body cover 12 forms a receiving space and is at least partially mounted on the frame 11. The wheel assembly 13 is located below the frame 11, and the wheel assembly 13 is connected to the suspension assembly 14, and the wheel assembly 13 is mounted to the frame 11 through the suspension assembly 14. The wheel assembly 13 includes front wheels 131 and rear wheels 132. In the illustrative embodiment, the front wheels 131 serve as the steering driven wheels of the electric motorcycle 100, and the rear wheels 132 serve as the drive wheels of the electric motorcycle 100. The suspension assembly 14 includes front suspensions 141 and rear suspensions 142, the front suspensions 141 are mounted on the front side of the frame 11, and the front wheels 131 are mounted on the front suspensions 141, and the rear suspensions 142 are mounted on the rear side of the frame 11, and the rear wheels 132 are mounted on the rear suspensions 142. The saddle assembly 15 includes a saddle 151 and a saddle cover 152, the saddle 151 is mounted on the frame 11, the saddle 151 is for the driver to sit on, and the saddle 151 and the saddle cover 152 are rotatably connected. The lighting assembly 16 is partially mounted on the frame 11, and the lighting assembly 16 is used to provide lighting and warning effects.

[0024] As Figures 2 to 4 shown, as an implementation, the electric motorcycle 100 further includes a control system 18, a cooling assembly 19, an air inlet assembly 24 and a power assembly 20. The power assembly 20 includes a motor 201, which can drive the rear wheels 132 to rotate, i.e. drive the electric motorcycle 100 to travel. The cooling assembly 19 includes a radiator 191 and a water pump 192, which are used to cool the electric motorcycle 100. The control system 18 includes a motor controller 181, which can receive instructions and issue instructions to control the motor 201. The air inlet assembly 24 is provided on the lower side of the electric motorcycle 100, and the air inlet assembly 24 is connected to the frame 11 and the vehicle body cover 12, and the air inlet assembly 24 extends substantially in the front-rear 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 inlet assembly 24 substantially wraps the lower side of the electric motorcycle 100, and the air inlet assembly 24 forms an air inlet air duct 241, which extends substantially in the front-rear direction of the electric motorcycle 100, facilitating the cooling of the radiator 191, the motor controller 181, the water pump 192 and the motor 201 by air cooling, and facilitating the improvement of the heat dissipation effect of the electric motorcycle 100, thereby improving the service life of the electric motorcycle 100. Among them, the air inlet air duct 241 refers to the flow channel through which air enters the air inlet assembly 24 and is discharged from the air inlet assembly 24 during the travel of the electric motorcycle 100.

[0025] As Figures 2 to 4As shown, specifically, the air inlet assembly 24 includes an air inlet 242, a second air outlet 243 and a first air outlet 244. In the front-rear direction of the electric motorcycle 100, the air inlet 242 is arranged on the front side of the vehicle body cover 12 and communicates with the air inlet duct 241, so as to make air enter the air inlet assembly 24 during driving of the electric motorcycle 100, thereby cooling the radiator 191, the motor controller 181, the water pump 192 and the motor 201 in the form of air cooling, which is conducive to improving the heat dissipation effect of the electric motorcycle 100, thereby improving the service life of the electric motorcycle 100. In the front-rear direction of the electric motorcycle 100, the first air outlet 244 is arranged near the motor 201, for discharging air out of the air inlet assembly 24. In the front-rear direction and the up-down direction of the electric motorcycle 100, the second air outlet 243 is located between the air inlet 242 and the first air outlet 244, i.e. the second air outlet 243 is located on the rear side of the air inlet 242, the second air outlet 243 is located on the front side of the first air outlet 244, and the second air outlet 243 is located on the lower side of the motor controller 181. Among them, the opening direction of the air inlet 242 is arranged forward, the opening direction of the second air outlet 243 is arranged downward, and the opening direction of the first air outlet 244 is arranged rearward. Through the above arrangement, during driving of the electric motorcycle 100, air can enter the air inlet 242 better, so that the air carries away the heat of the radiator 191, the motor controller 181, the water pump 192 and the motor 201, and then the heat is discharged out of the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, thereby improving the heat dissipation effect of the electric motorcycle 100. In addition, during driving of the electric motorcycle 100, mud and the like will enter the air inlet assembly 24 from the air inlet 242, by arranging the opening of the second air outlet 243 downward, the mud and the like can be discharged from the second air outlet 243, thereby effectively preventing the pollution and blockage of the air inlet assembly 24 by the mud and the like, which is conducive to improving the air inlet effect of the air inlet assembly 24, thereby improving the heat dissipation effect and service life of the electric motorcycle 100.

[0026] 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 delivered better 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.

[0027] 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.

[0028] 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.

[0029] As an implementation manner, the air inlet 242 is provided with a plurality of air inlet slopes 245. The air inlet slopes 245 are arranged in the up-down direction and the left-right direction of the electric motorcycle 100. The air inlet slopes 245 can prevent part of the mud and the like from entering the air inlet assembly 24, thereby effectively preventing the mud and the like from polluting and blocking the air inlet assembly 24, and facilitating to improve the air inlet effect of the air inlet assembly 24, and further improve the heat dissipation effect and the service life of the electric motorcycle 100. Specifically, the air inlet slope 245 is substantially perpendicular to the second projection plane 102. In the left-right direction of the electric motorcycle 100, the projection of the air inlet slope 245 on the second projection plane 102 is a first projection line, the projection of the first projection plane 101 on the second projection plane 102 is a second projection line, and the acute 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°. At this time, the air inlet slope 245 can effectively prevent part of the mud and the like from entering the air inlet assembly 24, thereby effectively preventing the mud and the like from polluting and blocking the air inlet assembly 24, and facilitating to improve the air inlet effect of the air inlet assembly 24, and further improve the heat dissipation effect and the service life of the electric motorcycle 100.

[0030] In the embodiment, in the up-down 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 air inlet slope 245 at the upper part is greater than the slope of the air inlet slope 245 at the lower part. Specifically, in the up-down direction of the electric motorcycle 100, the slopes of the plurality of air inlet slopes 245 gradually decrease from top to bottom. Since the trajectory of the mud and the like entering the air inlet assembly 24 is substantially a parabola, through the above arrangement, the mud and the like can be effectively blocked from entering the air inlet assembly 24, thereby facilitating to improve the air inlet effect of the air inlet assembly 24, and improving the heat dissipation effect and the service life of the electric motorcycle 100.

[0031] As an implementation manner, the air inlet assembly 24 and the frame 11 can be fixedly connected by bolts or the like, and the air inlet assembly 24 and the vehicle body cover 12 can be fixedly connected by bolts or buckles or the like, so as to stably connect the air inlet assembly 24 and the frame 11, and stably connect the air inlet assembly 24 and the vehicle body cover 12, thereby improving the air inlet effect of the air inlet assembly 24 during the driving of the electric motorcycle 100, and further improving the heat dissipation effect and the service life of the electric motorcycle 100.

[0032] As an implementation form, the air inlet assembly 24 further comprises a first side plate 246, a second side plate and a bottom plate 248. The first side plate 246 is arranged at the left side of the electric motorcycle 100, the second side plate is arranged at the right side of the electric motorcycle 100, and the bottom plate 248 is arranged at the lower side of the electric motorcycle. One side of the bottom plate 248 is connected with the first side plate 246, and the other side of the bottom plate 248 is connected with the second side plate. The first side plate 246, the second side plate and the bottom plate 248 jointly constitute the air inlet 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 inlet assembly 24, improving the air inlet effect of the air inlet assembly 24 during the driving 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 inlet assembly 24 and the replacement of the air inlet assembly 24.

[0033] As an implementation form, the air inlet 242 comprises a plurality of air inlet holes 2421, and a hole wall is arranged between adjacent air inlet holes 2421. The adjacent air inlet holes 2421 are spaced apart by the hole wall. This facilitates the air to enter the air inlet assembly 24 through the plurality of air inlet holes 2421 during the driving of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the opening of the air inlet hole 2421 is arranged forward along the front-rear direction of the electric motorcycle 100. Through the above arrangement, the air can enter the air inlet assembly 24 through the air inlet hole 2421 during the driving of the electric motorcycle 100, thereby enabling the air to take away the heat of the radiator 191, the motor controller 181, the water pump 192 and the motor 201, and further enabling the heat to be discharged out of the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the air inlet hole 2421 can be adjusted according to requirements or the external structure of the electric motorcycle 100, so as to meet the requirement that the amount of air entering the air inlet assembly 24 is sufficient without changing the external structure of the electric motorcycle 100, thereby improving the space utilization and resource utilization of the electric motorcycle 100.

[0034] In the present embodiment, an air inlet slope 245 is arranged in each air inlet hole 2421. The air inlet slope 245 can provide a buffering effect when the air enters the air inlet hole 2421, thereby reducing the resistance of the air inlet assembly 24 during the driving of the electric motorcycle 100 and improving the driving speed of the electric motorcycle 100. In addition, the air inlet slope 245 can effectively prevent part of the mud and the like from entering the air inlet assembly 24 through the air inlet hole 2421, thereby effectively preventing the pollution and blockage of the air inlet assembly 24 by the mud and the like, which is conducive to improving the air inlet effect of the air inlet assembly 24 and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0035] Specifically, along the up-down 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 inlet slope 245 of the air inlet hole 2421 at the upper part is larger than that of the air inlet hole 2421 at the lower part. Again, since the trajectory of mud and the like entering the air inlet assembly 24 is basically a parabola, through the above setting, the mud and the like can be effectively blocked from entering the air inlet assembly 24, thereby improving the air inlet effect of the air inlet assembly 24 and improving the heat dissipation effect and service life of the electric motorcycle 100.

[0036] As an implementation manner, the left side of the electric motorcycle 100 is provided with a first air inlet, and the right side is provided with a second air inlet, so as to facilitate the air entering the air inlet assembly 24 through the first air inlet and the second air inlet during the driving of the electric motorcycle 100. Through the above setting mode, the air inlet amount can be improved, so as to cool the radiator 191, the motor controller 181, the water pump 192 and the motor 201 in the form of air cooling, which is conducive to improving the heat dissipation effect of the electric motorcycle 100, thereby improving the service life of the electric motorcycle 100.

[0037] In the embodiment, the first air inlet includes a plurality of first air inlet holes, and a hole wall is arranged between adjacent first air inlet holes. The adjacent first air inlet holes are separated by the hole wall, so as to facilitate the air entering the air inlet assembly 24 through the plurality of first air inlet holes during the driving of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, along the front-rear direction of the electric motorcycle 100, the opening of the first air inlet hole is arranged forward. Through the above setting, during the driving of the electric motorcycle 100, the air can enter the air inlet assembly 24 through the first air inlet hole better, so that the air carries away the heat of the radiator 191, the motor controller 181, the water pump 192 and the motor 201, and then the heat is discharged out of the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the first air inlet hole can be adjusted according to the demand or the external structure of the electric motorcycle 100, so as to meet the condition that the air amount entering the air inlet assembly 24 is sufficient without changing the external structure of the electric motorcycle 100, thereby improving the space utilization and resource utilization of the electric motorcycle 100.

[0038] Specifically, a first air inlet slope is arranged in each first air inlet hole, which can provide a buffering effect when air enters the first air inlet hole, so that the air inlet assembly 24 has smaller resistance during the driving of the electric motorcycle 100, and the driving speed of the electric motorcycle 100 is improved. In addition, the first air inlet slope can effectively prevent some mud and the like from entering the air inlet assembly 24 through the first air inlet hole, thereby effectively preventing the air inlet assembly 24 from being polluted and blocked by the mud and the like, and improving the air inlet effect of the air inlet assembly 24, thereby improving the heat dissipation effect and service life of the electric motorcycle 100.

[0039] In the embodiment, the second air inlet includes a plurality of second air inlet holes, and a hole wall is arranged between adjacent second air inlet holes. The adjacent second air inlet holes are separated by the hole wall, so that air can enter the air inlet assembly 24 through the plurality of second air inlet holes during the driving of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the opening of the second air inlet hole is arranged forward along the front-rear direction of the electric motorcycle 100. Through the above arrangement, air can enter the air inlet assembly 24 through the second air inlet hole during the driving of the electric motorcycle 100, so that the air carries away the heat of the radiator 191, the motor controller 181, the water pump 192 and the motor 201, and then the heat is discharged out of the electric motorcycle 100 through the first air outlet 244 and the first air outlet 244, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the second air inlet hole can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that the air amount entering the air inlet assembly 24 is sufficient without changing the external structure of the electric motorcycle 100, thereby improving the space utilization and resource utilization of the electric motorcycle 100.

[0040] Specifically, a second air inlet slope is arranged in each second air inlet hole, which can provide a buffering effect when air enters the second air inlet hole, so that the air inlet assembly 24 has smaller resistance during the driving of the electric motorcycle 100, and the driving speed of the electric motorcycle 100 is improved. In addition, the second air inlet slope can effectively prevent some mud and the like from entering the air inlet assembly 24 through the second air inlet hole, thereby effectively preventing the air inlet assembly 24 from being polluted and blocked by the mud and the like, and improving the air inlet effect of the air inlet assembly 24, thereby improving the heat dissipation effect and service life of the electric motorcycle 100.

[0041] As Figure 5As shown, as an implementation form, the electric motorcycle 100 further comprises a footrest assembly 25 and a steering assembly 26. The steering assembly 26 is connected to the suspension assembly 14, and the steering assembly 26 is arranged on the frame 11 and used to control the moving direction of the electric motorcycle 100. Specifically, the steering assembly 26 is connected to the front suspension 141, so as to control the steering of the front wheel 131 through the front suspension 141, and further control the moving direction of the electric motorcycle 100. The footrest assembly 25 is arranged at least partially on the frame 11 and used to place and support the driver's feet. Specifically, the footrest assembly 25 is connected to the frame 11 by means of bolts or other fixing methods, so as to realize the stable connection between the footrest assembly 25 and the frame 11. In the embodiment, the footrest assembly 25 is arranged at least partially between the steering assembly 26 and the saddle assembly 15, and the footrest assembly 25 extends substantially along the front-rear direction of the electric motorcycle 100.

[0042] As an implementation form, in a first projection plane 101 perpendicular to the up-down direction of the electric motorcycle 100, the axis of the front wheel 131 has a first projection line in the up-down direction in the first projection plane 101, and the axis of the rear wheel 132 has a second projection line in the up-down direction of the electric motorcycle 100 in the first projection plane 101; the front end of the footrest assembly 25 has a third projection line in the up-down direction of the electric motorcycle 100 in the first projection plane 101; and the rear end of the footrest assembly 25 has a fourth projection line in the up-down direction of the electric motorcycle 100 in the first projection plane 101. The footrest assembly 25 is arranged substantially parallel to the first projection plane 101.

[0043] In the front-rear direction of the electric motorcycle 100, the distance between the first projection line and the second projection line is a first distance D1, and the distance between the third projection line and the fourth projection line is a second distance D2, and 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. The first distance D1 is the shortest distance between the first projection line and the second projection line, and the second distance D2 is the shortest distance between the third projection line and the fourth projection line. Within this distance range, the footrest assembly 25 can provide more comfortable support for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and further improving the human-machine interaction of the electric motorcycle 100. In addition, under the condition of providing comfortable support for the driver's feet, the structure of the electric motorcycle 100 is more compact, which can improve the overall compactness of the electric motorcycle 100, so that the electric motorcycle 100 has better mobility during driving, thereby improving the driving operability of the driver.

[0044] In the embodiment, the ratio of the first distance D1 and 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 and the second distance D2 is greater than or equal to 5 and less than or equal to 6, the footrest assembly 25 can provide more comfortable support for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-computer interaction of the electric motorcycle 100. In addition, under the condition of meeting the comfortable support for the driver's feet, the structure of the electric motorcycle 100 is more compact, which can improve the compactness of the whole electric motorcycle 100, so that the electric motorcycle 100 has better mobility during driving, and improves the driving operability of the driver.

[0046] As an implementation manner, the electric motorcycle 100 further comprises a saddle assembly 15, the saddle assembly 15 comprising a saddle 151 and a saddle cover 152, and the saddle 151 and the saddle cover 152 are rotationally connected. The saddle cover 152 is provided with a seat point 1521. The seat point 1521 refers to the point at which the driver sits on the saddle cover 152. The steering assembly 26 comprises a handle mechanism 261, which can be a steering handle 2611, and the steering handle 2611 is arranged on both sides of the electric motorcycle 100. The steering handle 2611 is basically a cylinder. When the electric motorcycle 100 is driving straight, the steering handle 2611 is in a balanced state, at this time, the steering handle 2611 basically extends along the left-right direction of the electric motorcycle 100. In the up-down direction of the electric motorcycle 100, the projection of the axis line of the steering handle 2611 on the first projection plane 101 is a fifth projection line, and the projection of the seat point 1521 on the first projection plane 101 is a first projection point. In the front-rear direction of the electric motorcycle 100, the distance between the fifth projection line and the first projection line is a third distance D3, and the shortest distance between the first projection point and the first projection line is a fourth distance D4. The third distance D3 is the shortest distance between the fifth projection line and the first projection line.

[0047] Specifically, the ratio of the first distance D1 and the third distance D3 is greater than or equal to 2.4 and less than or equal to 3.7. At this time, the steering assembly 26 can provide a more comfortable grip for the driver's hands, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100. The ratio of the first distance D1 and the fourth distance D4 is greater than or equal to 1.2 and less than or equal to 1.9. At this time, the saddle assembly 15 can provide a more comfortable support for the driver, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100.

[0048] Specifically, the ratio of the first distance D1 and the third distance D3 is greater than or equal to 2.8 and less than or equal to 3.3. At this time, the steering assembly 26 can provide a more comfortable grip for the driver's hands, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100. The ratio of the first distance D1 and the fourth distance D4 is greater than or equal to 1.4 and less than or equal to 1.7. At this time, the saddle assembly 15 can provide a more comfortable support for the driver, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100.

[0049] In the present embodiment, the ratio of the first distance D1 and the third distance D3 is 3. At this time, the steering assembly 26 can provide a more comfortable grip for the driver's hands, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100. The ratio of the first distance D1 and the fourth distance D4 is 1.5. At this time, the saddle assembly 15 can provide a more comfortable support for the driver, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100.

[0050] Specifically, when the ratio of the first distance D1 and the third distance D3 is 3, and the ratio of the first distance D1 and 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 further improving the service life and driving operability of the electric motorcycle 100.

[0051] As an implementation manner, the vehicle body cover 12 is provided with a foot guard plate 121 on the side close to the driver's feet, and the foot guard plate 121 extends substantially in the up-down direction of the electric motorcycle. In the front-rear direction of the electric motorcycle 100, the front side of the saddle assembly 15, the rear side of the foot guard plate, and the upper side of the footrest assembly 25 jointly constitute the accommodation space 27.

[0052] In the second projection plane 102 perpendicular to the left-right direction of the electric motorcycle 100, the accommodation space 27 has a first projection area greater than or equal to 0.09 square meters and less than or equal to 0.13 square meters. When the first projection area is greater than or equal to 0.09 square meters and less than or equal to 0.13 square meters, the accommodation space 27 can provide a more comfortable placement space for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-computer interaction of the electric motorcycle 100.

[0053] Specifically, the first projection area is greater than or equal to 0.1 square meters and less than or equal to 0.12 square meters. When the first projection area is greater than or equal to 0.1 square meters and less than or equal to 0.12 square meters, the accommodation space 27 can provide a more comfortable placement space for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-computer interaction of the electric motorcycle 100.

[0054] In the present embodiment, the first projection area is 0.11 square meters. At this time, the accommodation space 27 can provide a more comfortable placement space for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-computer interaction of the electric motorcycle 100. In addition, when the fifth projection area is 0.11 square meters, the structure of the electric motorcycle 100 is more compact under the condition of providing a comfortable placement space for the driver's feet, and the overall compactness of the electric motorcycle 100 can be improved, thereby making the electric motorcycle 100 have better mobility during driving, and improving the driving operability of the driver.

[0055] As Figure 6As shown, as an implementation manner, the electric motorcycle 100 further comprises a power supply device 17, a control system 18 and a power assembly 20. The power assembly 20 comprises a motor 201, which is capable of driving the rear wheel 132 to rotate, i.e. driving the electric motorcycle 100 to travel. The motor 201 is provided with a first rotating shaft 2011 extending substantially along the left-right direction of the electric motorcycle 100, and the motor 201 is capable of driving the first rotating shaft 2011 to rotate. The control system 18 comprises a motor controller 181 capable of receiving instructions and issuing instructions to control the motor 201. The motor controller 181 can be mounted on the frame 11. The frame 11 encloses a first space below the footrest assembly 25. The first space can limit the motor controller 181, improving the assembly stability of the motor controller 181. Specifically, along the up-down direction of the electric motorcycle 100, the motor controller 181 is arranged below the footrest assembly 25, and the motor controller 181 is wrapped by the first space, the footrest assembly 25 and the air inlet assembly 24, thereby ensuring the stability of the motor controller 181 and enabling the motor controller 181 to better control the motor 201. The power supply device 17 comprises a power storage element 171 mounted on the frame 11 and located in the saddle 151, for providing power for the electric motorcycle 100.

[0056] In the embodiment, in a first projection plane 101 perpendicular to the up-down direction of the electric motorcycle 100, the axis of the motor 201 has a sixth projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100, i.e. the axis of the first rotating shaft 2011 has a sixth projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100; the power storage element 171 has a first symmetry plane 103 extending along the left-right direction of the electric motorcycle 100, the first symmetry plane 103 has a seventh projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100; the axis of the rear wheel 132 has an eighth projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100; along the front-rear direction of the electric motorcycle 100, the distance between the sixth projection line and the eighth projection line is L1, and the distance between the seventh projection line and the eighth projection line is L2. The distance L1 is greater than or equal to 350 mm and less than or equal to 430 mm.

[0057] As an implementation manner, the difference between L2 and L1 is greater than 0 mm and less than or equal to 600 mm. At this time, since the weights of the power storage element 171 and the motor 201 are heavy in the electric motorcycle 100, the positions of the power storage element 171 and the motor 201 can be reasonably arranged by the above setting, so that the power storage element 171 and the motor 201 are arranged along the front-rear direction of the electric motorcycle 100, so that the electric motorcycle 100 remains in a relatively stable state, improves the stability and balance of the electric motorcycle 100, and then remains stable when the electric motorcycle 100 is at rest and driving, and improves the driving safety. Specifically, along the front-rear direction of the electric motorcycle 100, the motor 201 can be arranged at the front side of the power storage element 171, and the motor 201 can also be arranged at the rear side of the power storage element 171.

[0058] In the embodiment, the difference between L2 and L1 is greater than or equal to 220 mm and less than or equal to 500 mm. At this time, since the weights of the power storage element 171 and the motor 201 are heavy in the electric motorcycle 100, the positions of the power storage element 171 and the motor 201 can be reasonably arranged by the above setting, so that the power storage element 171 and the motor 201 are arranged along the front-rear direction of the electric motorcycle 100, so that the electric motorcycle 100 remains in a relatively stable state, improves the stability and balance of the electric motorcycle 100, and then remains stable when the electric motorcycle 100 is at rest and driving, and improves the driving safety.

[0059] As an implementation manner, the motor controller 181 has a second symmetry plane 104 extending along the left-right direction of the electric motorcycle 100, and the second symmetry plane 104 has a ninth projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100. Along the front-rear direction of the electric motorcycle 100, the distance between the ninth projection line and the eighth projection line is L3. The difference between L3 and L1 is greater than or equal to 270 mm and less than or equal to 510 mm. At this time, since the weights of the motor controller 181 and the motor 201 are heavy in the electric motorcycle 100, the positions of the motor controller 181 and the motor 201 can be reasonably arranged by the above setting, so that the motor controller 181 and the motor 201 are arranged along the front-rear direction of the electric motorcycle 100, so that the electric motorcycle 100 remains in a relatively stable state, improves the stability and balance of the electric motorcycle 100, and then remains stable when the electric motorcycle 100 is at rest and driving, and improves the driving safety. Specifically, along the front-rear direction of the electric motorcycle 100, the motor controller 181 is located at the front side of the motor 201.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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 3, the rated power of the motor 201 is greater than or equal to 5kw and less than or equal to 12.5kw, and 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 357kw / m 3 and less than or equal to 1250kw / m 3 . Through the above setting mode, the size of the storage power element 171 can be controlled by controlling the size of the space accommodating the storage power element 171. At this time, the volume of the storage power element 171 is basically consistent with the volume of the second accommodating space 1511. At this time, when the volume of the storage power element 171 is constant, the storage capacity of the storage power element 171 is constant, so that the storage power element 171 with smaller storage capacity can provide the motor 201 with larger power output, improve energy utilization rate and reduce resource waste.

[0064] Specifically, the volume of the second accommodating space 1511 is greater than or equal to 0.011m 3 and less than or equal to 0.013m 3 , the rated power of the motor 201 is greater than or equal to 7kw and less than or equal to 10kw, and 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 538kw / m 3 and less than or equal to 910kw / m 3 . Through the above setting mode, the size of the storage power element 171 can be controlled by controlling the size of the space accommodating the storage power element 171. At this time, the volume of the storage power element 171 is basically consistent with the volume of the second accommodating space 1511. At this time, when the volume of the storage power element 171 is constant, the storage capacity of the storage power element 171 is constant, so that the storage power element 171 with smaller storage capacity can provide the motor 201 with larger power output, improve energy utilization rate and reduce resource waste.

[0065] In the embodiment, the volume of the second accommodating space 1511 is 0.012m 3 , the rated power of the motor 201 is 12.5kw, and the ratio of the rated power of the motor 201 to the volume of the second accommodating space 1511 is 1042kw / m 3 . Through the above setting mode, the size of the storage power element 171 can be controlled by controlling the size of the space accommodating the storage power element 171. At this time, the volume of the storage power element 171 is basically consistent with the volume of the second accommodating space 1511. At this time, when the volume of the storage power element 171 is constant, the storage capacity of the storage power element 171 is constant, so that the storage power element 171 with smaller storage capacity can provide the motor 201 with larger power output, improve energy utilization rate and reduce resource waste.

[0066] As an implementation manner, 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 357kw / m3 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.

[0067] 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.

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, 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.

[0069] 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.
