[0002] Electric motorcycles have become a common and convenient mode of transportation in daily life. The national standard "General Technical Conditions for Electric Motorcycles and Electric-Assisted Bicycles" (hereinafter referred to as the "Electric Motorcycle Standard") was released on June 25, 2009, and implemented on January 1, 2010. According to this standard, two-wheeled or three-wheeled vehicles with a maximum design speed greater than 20 km / h and less than 50 km / h, powered by electricity, are called mopeds or electric motorcycles, and electric motorcycles or mopeds fall under the category of motor vehicles.

[0003] When the maximum speed of an electric motorcycle is below 50 km / h, the vibration frequency is relatively low, and the requirements for body strength and battery range are also relatively low. However, when the speed of an electric motorcycle increases to above 50 km / h, the vibration frequency increases, and the requirements for body strength and battery storage capacity become higher.

[0004] To meet the requirement that electric motorcycles can travel at speeds greater than 50 km / h, it is necessary to reduce the vibration frequency of electric motorcycles and improve their handling stability and comfort. Utility Model Content

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] like Figure 1As shown, an electric motorcycle 100 includes a frame 11, a running system 12, a power system 13, a transmission mechanism 14, a steering system 15, an electrical system 16, and a power supply unit 17. The running system 12 includes a front wheel and a rear wheel for moving the electric motorcycle 100. The power system 13 includes a motor 131 for driving the front wheel and / or the rear wheel. The transmission mechanism 14 is at least partially connected to the motor 131 for transmitting power from the motor 131 to the front wheel and / or the rear wheel. The steering system 15 is at least partially connected to the frame 11 and includes a left handlebar 151 and a right handlebar 152. The electrical system 16 includes at least one handlebar switch 161 and an electronic display screen 162. The handlebar switch 161 is sleeved on the outside of the handlebars, and the electronic display screen 162 is supported by the frame 11 between the left handlebar 151 and the right handlebar 152. The power supply unit 17 provides electrical energy to the electric motorcycle 100. As one implementation, the electric motorcycle 100 also includes a seat bucket 18, which is used to store at least the battery that provides power to the electric motorcycle 100.

[0039] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The left, right, front, and rear sides shown are the left, right, front, and rear sides of the electric motorcycle 100. At the same time, the direction closer to the ground is the lower side of the electric motorcycle 100, and the direction farther from the ground is the upper side of the electric motorcycle 100.

[0040] like Figures 2 to 3 As shown, the frame 11 includes a front frame 111 and a rear frame 112. The frame 11 also includes a suspension structure 113. The motor 131 is mounted under the frame 11 via the suspension structure 113. The suspension structure 113 includes a housing 1131, which at least partially covers the outside of the motor 131. At least a portion of the housing 1131 extends in a direction parallel to the circumference of the motor 131, thereby forming a housing space within the housing 1131 to accommodate the motor 131. The motor 131 is installed and arranged within the housing space, so that the housing 1131 can fix the motor in the circumference of the motor. This arrangement helps to improve the stability of the fixation between the motor and the frame. At the same time, separating the motor 131 from other components can also improve the protection performance of the motor 131.

[0041] As one implementation, the housing 1131 is open on one side, and has multiple air inlets 1132. These air inlets 1132 are configured to allow airflow to pass through and reach the surface of the motor 131. Thus, during the movement of the electric motorcycle 100, oncoming airflow can enter the housing 1131 through the air inlets 1132. The airflow entering the housing 1131 blows onto the surface of the motor 131, carrying away the heat emitted by the motor 131, and then dissipates on the other side of the housing 1131. This achieves air cooling of the motor 131, preventing it from overheating during operation.

[0042] Simultaneously, by adjusting the number of air inlets 1132, the weight of the housing 1131 can be adjusted, thereby changing the natural frequency of the housing 1131; consequently, the natural frequency of the frame 11 connected to the housing 1131 is changed. In other words, in this application, the natural frequency of the frame 11 is changed by altering the number of air inlets 1132 on the housing 1131, so that the resonant frequency point of the electric motorcycle 100 avoids the commonly used speed range.

[0043] In one specific embodiment of this application, the resonant frequency of the electric motorcycle 100 is adjusted by changing the number of air inlets 1132, so that the resonance of the electric motorcycle 100 occurs in the speed range below 10 km / h. This setting, by avoiding the occurrence of the resonance frequency point in the speed range most commonly used by the electric motorcycle 100, can effectively prevent abnormal noises and bumps caused by resonance during driving.

[0044] As one implementation method, the multiple air inlets 1132 can be arranged evenly or in an array on the outer peripheral surface of the housing 1131. For example, the multiple air inlets 1132 can form an array in pairs and be evenly distributed on the windward side surface of the housing 1131.

[0045] like Figure 3 As shown, the housing 1131 also includes a cover 1133 and a mounting plate 1134. The cover 1133 extends along the circumferential direction of the motor 131, and the mounting plate 1134 extends from both sides of the cover 1133 in a direction perpendicular to the axis of the motor 131. Thus, the cover 1133 and the mounting plates 1134 located on both sides of the cover 1133 form an accommodating space for accommodating the motor 131. Simultaneously, the mounting plate 1134 is arranged perpendicular to the axis of the motor 131. This arrangement facilitates improving the levelness of the motor 131 during assembly and helps to enhance the stability of the motor 131's output.

[0046] The mounting plate 1134 is symmetrically provided with at least three pairs of motor mounting holes for fixing the motor 131, thereby achieving a fixed connection between the motor 131 and the housing 1131.

[0047] When the motor mounting holes are set to three pairs, the three pairs of motor mounting holes are respectively distributed at the two ends of the arc-shaped mounting plate 1134 and at the middle position between the two ends, thereby fixing the motor 131 through three fixing points. Setting the three fixing points on the same suspension structure 113 reduces the number of components connected to the motor 131. This arrangement provides convenient conditions for adjusting the resonance frequency between the motor 131, the suspension structure 113, and the frame 11.

[0048] As one implementation method, the housing 1131 is manufactured by integral molding; the integral molding process helps to further ensure product consistency and improve product assembly efficiency.

[0049] Meanwhile, in order to facilitate processing and assembly, the cover 1133 is arranged parallel to the circumferential surface of the motor 131; that is, the cover 1133 extends in an arc shape around the outer periphery of the motor 131; wherein, the cover 1133 covers at least one-quarter of the circumferential surface of the motor 131 to ensure that the housing 1131 has a certain rigidity and strength.

[0050] like Figure 4 As shown, the suspension structure 113 also includes a bracket 1135, which includes a first connecting plate 1136 and a second connecting plate 1137 that are respectively connected to the vehicle frame 11, and at least one crossbeam that is fixedly connected to the first connecting plate 1136 and the second connecting plate 1137. The housing 1131 is fixedly connected to the crossbeam, thereby achieving a fixed connection between the motor 131 and the vehicle frame 11 through the bracket 1132.

[0051] Specifically, the first connecting plate 1136 and the second connecting plate 1137 are fixedly connected to the rear frame 112, and preferably, the first connecting plate 1136 and the second connecting plate 1137 are fixed to the bottom of the rear frame 112 by welding.

[0052] In one specific embodiment of this application, the crossbeam includes a first crossbeam 1138 and a second crossbeam 1139, with the housing 1131 fixedly connected to both the first crossbeam 1138 and the second crossbeam 1139. The two ends of the first crossbeam 1138 and the second crossbeam 1139 are fixedly connected to a first connecting plate 1136 and a second connecting plate 1137, respectively. The first crossbeam 1138 is located at the front of the motor 131, and the second crossbeam 1139 is located above the motor 131. The second crossbeam 1139 can also be used to support the seat bucket 15 of the electric motorcycle 100. Preferably, both the first crossbeam 1138 and the second crossbeam 1139 are tubular components with a circular cross-section.

[0053] To facilitate assembly, both the first connecting plate 1136 and the second connecting plate 1137 are provided with clearance holes. Specifically, the first connecting plate 1136 is provided with bolt clearance holes to facilitate the passage of bolts, and the second connecting plate 1137 is provided with torque tool clearance holes to facilitate the fixing of self-locking nuts by torque tools.

[0054] Furthermore, the housing 1131 is also provided with at least one groove for welding and fixing to the crossbeam. The shape of the groove matches the outer circumferential shape of the crossbeam, thereby facilitating the welding of the housing 1131 to the crossbeam during the assembly process.

[0055] Motor 131 is located between the front and rear wheels, and includes an output shaft that extends along the width of the vehicle. Figure 5 As shown, the transmission mechanism 14 includes a drive wheel 141, a transmission wheel, and a transmission belt 142. The drive wheel 141 is connected to one end of the output shaft of the motor 131, and the output shaft can drive the drive wheel 141 to rotate. The transmission wheel is mounted on the front or rear wheel, and the drive wheel 141 is connected to the transmission wheel via the transmission belt 142. The motor 131 outputs torque through its output shaft, causing the output shaft to drive the drive wheel 141 to rotate. The drive wheel 141 drives the transmission wheel to rotate via the transmission belt 142, thereby driving the front or rear wheel of the electric vehicle to rotate. Preferably, the transmission belt 142 can be, for example, a belt 142, which can be made of rubber and is fitted between the drive wheel 141 and the transmission wheel with a certain tension. This can absorb and buffer vibrations and impacts from the motor 131 and the wheel, which helps to reduce the noise generated during the operation of the electric motorcycle 100 and improve the stability and safety of the electric motorcycle 100.

[0056] Furthermore, in order to improve the synchronization of the transmission, the belt 142 can be, for example, a toothed belt 142, which meshes with the drive wheel 141 or the transmission wheel to realize the torque transmission between the drive wheel 141 and the transmission wheel.

[0057] Among them, such as Figure 6As shown, the tooth height of the drive wheel 141 and / or the transmission wheel is greater than the tooth height of the toothed belt 142, resulting in a gap 143 between the teeth of the drive wheel 141 or the transmission wheel and the teeth of the toothed belt 142 when the drive wheel 141 or the transmission wheel meshes with the toothed belt 142 during torque transmission. By setting the gap 143, the friction generated between the teeth of the drive wheel 141 and the teeth of the toothed belt 142, and between the teeth of the transmission wheel and the teeth of the toothed belt 142 during transmission, can be reduced, thereby reducing the noise generated by mutual friction during torque transmission.

[0058] Optionally, the tooth height of the drive wheel 141 and / or the transmission wheel is at least higher than the tooth height of the toothed belt 142. As one implementation, the difference between the tooth height of the drive wheel 141 and / or the transmission wheel and the tooth height of the toothed belt 142 ranges from 0.06 mm to 0.2 mm. More specifically, the difference ranges from 0.08 mm to 0.16 mm. More specifically, the difference ranges from 0.1 mm to 0.14 mm; as one implementation, the tooth height of the transmission wheel can be, for example, 3.55 mm, and the tooth height of the toothed belt can be 3.45 mm.

[0059] As one implementation method, motor 131 can be a four-pole motor or an eight-pole motor. Compared to the original two-pole motor, four-pole or eight-pole motors operate more smoothly and quietly at high speeds, and are more efficient, making them suitable for the high-speed operation requirements of electric motorcycles 100cc. Meanwhile, the stator and other components inside motor 131 are sealed inside the motor 131 using potting compound, which further improves the stability of the internal components and makes the motor 131 operate more smoothly.

[0060] Furthermore, the motor 131 is provided with a motor fixing part, which protrudes from the circumferential surface of the motor and extends along the axial direction of the motor; the motor fixing part may also be provided with a motor fixing hole, which penetrates the motor fixing part. During the assembly of the motor 131, the fixing bolt passes through the motor mounting hole on one side of the mounting plate 1134, then through the motor fixing hole of the motor 131, and then through the motor mounting hole on the other side of the mounting plate 1134 to be threadedly connected to the self-locking nut, thereby fixing the motor 131 with bolts. With this installation method, after the motor 131 and the assembly mechanism 113 are assembled, the bolts penetrate the housing of the motor 131 axially, and the bolts and nuts fix the motor 131 from both sides, further improving the stability of the motor 131. At the same time, while increasing the fixing points between the motor 131 and the assembly mechanism 113, the number of fixing components is reduced.

[0061] It is foreseeable that the electric motorcycle 100 provided in this application achieves a fixed connection between the motor 131 and the frame 11 through a suspension structure 113 that is at least partially covered in front of the motor 131, thereby improving the overall rigidity and strength of the frame 11. The ventilation holes 1132 provided on the housing 1131 facilitate cooling of the motor 131. Furthermore, adjusting the number of air inlets 1132 allows for adjustment of the weight of the housing 1131, thereby changing the natural frequency of the housing 1131, and consequently altering the natural frequency of the frame 11 connected to the housing 1131. By changing the assembly method between the motor 131 and the suspension structure 113, the overall rigidity and strength of the motor 131 are improved. While ensuring stability, the number of fixed components is reduced; by adopting belt drive and making the tooth height of the drive wheel 141 and / or the transmission wheel greater than the tooth height of the toothed belt, the noise generated by mutual friction during torque transmission is reduced; the electric motorcycle 100 provided in this application reduces the noise generated during the operation of the electric motorcycle 100 by adjusting the assembly method of the motor 131 and the torque transmission method, and adjusts the occurrence range of the resonance frequency point of the electric motorcycle 100 by adjusting the natural frequency of the suspension structure, which can effectively avoid abnormal noise and bumps caused by resonance during the operation of the electric motorcycle 100, and improve the stability and safety of the electric motorcycle 100.

[0062] like Figure 7 As shown, the frame 11 includes a front frame 111 and a rear frame 112, wherein the lower part of the rear frame 112 is provided with a bracket assembly 114 for supporting the motorcycle, the bracket assembly 114 for providing support for the electric motorcycle 100 in the parked state.

[0063] like Figure 8 and Figure 9 As shown, the bracket assembly 114 includes a bracket mounting portion 1141, a side bracket 1142, and a tension spring 1143. The side bracket 1142 is hinged to the bracket mounting portion 1141. The side bracket 1142 has a retracted folded position A and a parking position B that engages with the ground, and is rotatable about the bracket mounting portion 1142, thereby being able to switch between the parking position B and the folded position A. The tension spring 1143 is connected between the side bracket 1142 and the bracket mounting portion 1141. The tension spring 1143 has a spring dead point position C, which is located between 60° and 70° of rotation from the folded position A to the parking position B.

[0064] Specifically, such as Figure 8As shown by the dashed line C, the dead point position of the tension spring 1143 refers to the position where the line of action between the side bracket 1142 and the tension spring 1143 is on a straight line and no component force (rotational torque) is generated that causes the side bracket 1142 to rotate. After the side bracket 1142 is hinged to the bracket mounting part 1141, the side bracket 1142 can resist the action of the spring force and rotate from the pivoting folding position A to the parking position B via the dead point position of the tension spring 1143, thereby achieving support for the electric motorcycle 100.

[0065] In this application, the tension spring 1143 is configured such that its dead point is located between 60° and 70° from the folded position A to the parking position B, making the dead point relatively closer to the front of the motorcycle. This ensures that during parking, the dead point is within the range of the thrust applied by the rider to the side support, preventing the side support 1142 from stopping at a position between the dead point and the folded position A due to lack of spring force after passing the dead point. Consequently, it is easier for the rider to push or pull the side support 1142 from the folded position A to the parking position B during parking, thus improving the user experience.

[0066] Preferably, the tension spring 1143 is configured such that the spring dead point is located between 65° and 70° of rotation from the folded position A to the parking position B, for example, 66°.

[0067] like Figure 9 As shown, in one specific embodiment, the end of the side bracket 1142 forms a receiving space, and the bracket mounting portion 1141 is at least partially disposed within the receiving space; the portion of the bracket mounting portion 1141 located in the receiving space has a first through hole, and the end of the side bracket 1142 has a second through hole, the second through hole communicating with the first through hole. The bracket mounting portion 1141 also includes a pivot member 1141a, and the pivot member 1144 of the side bracket 1142 is axially disposed through the first through hole and the second through hole, thereby enabling a rotatable connection between the side bracket 1142 and the bracket mounting portion 1141.

[0068] Specifically, the pivot 1144 is a fixing bolt, which passes through the first through hole and the second through hole and is fixedly connected to the nut; while realizing the fixed connection between the side bracket 1142 and the bracket mounting part 1141, it also enables the side bracket 1142 to rotate about the fixing nut as the axis.

[0069] A first spring fixing part 1141a is provided on one side of the bracket mounting part 1141, and a second spring fixing part 1142a is provided on the same side of the side bracket 1142 as the first spring fixing part 1141a. Both ends of the tension spring 1143 are detachably connected to the first spring fixing part 1141a and the second spring fixing part 1142a, respectively. Preferably, the first spring fixing part 1141a can be, for example, a first locking pin, used to lock the proximal end of the tension spring 1143, and the first locking pin protrudes in a direction perpendicular to the inner surface of the bracket mounting part 1141. The second spring fixing part 1142a can be, for example, a second locking pin, wherein the second locking pin is provided on the inner surface of approximately the central portion in the longitudinal direction of the side bracket 1142. The locking pin can also be in the form of a locking lug, and the locking pin or locking lug has a recess for fixing the end of the tension spring 1143.

[0070] Furthermore, after the side bracket 1142 rotates 110 degrees from the folded position A to the parking position B, it reaches the parking position B. At this time, the motorcycle is in a stable parking state through the three points of contact between the side bracket 1142 and the ground, and the front and rear wheels of the motorcycle.

[0071] In another embodiment, such as Figure 7 As shown, the bracket mounting portion 1141 is also provided with a limiting portion 1141b. This limiting portion 1141b is configured to abut against the front side of the side bracket 1142 when the side bracket 1142 rotates to the parking position B of 110°, so as to limit the side bracket 1142 when it is in the parking position B, thereby keeping it in the parking state. Preferably, the limiting portion 1141 is a limiting pin, which is fixed to the outside of the bracket mounting portion 1141, that is, the opposite side to the first spring fixing portion 1141a.

[0072] The side bracket 1142 also includes a side bracket base 1142a for supporting the motorcycle in the parked state and a kick part 1142b for facilitating the driver to put the side bracket 1142 into the parked state. The side bracket 1142 can be integrally formed by forging, thereby ensuring that the side bracket 1142 has high strength and rigidity to meet the support requirements of the motorcycle. At the same time, the integral forming process also helps to ensure the consistency of components and improves assembly efficiency.

[0073] Preferably, the side bracket 1142 is made of aluminum alloy, which not only ensures its high strength but also further improves the overall aesthetics of the electric motorcycle 100.

[0074] It is foreseeable that the electric motorcycle 100 provided in this application, by setting the dead point of the tension spring 1143 between 60° and 70° when rotating from the folding position A to the parking position B, makes the dead point of the spring relatively closer to the front side of the motorcycle. This ensures that during parking, the dead point of the spring is within the range of the thrust applied by the rider to the side support, so that the side support 1142 will not stop at a position between the dead point and the folding position A due to lack of spring force after passing the dead point. This makes it easier for the rider to push and pull the side support 1142 from the folding position A to the parking position B during parking, which is beneficial to improving the user experience of the rider.

[0075] like Figure 10 As shown, the electric motorcycle 100 of this application includes a seat bucket 18, and a seat cushion can cover the seat bucket 18. A rotating shaft is provided on the front side of the seat cushion, and the seat cushion is rotatably connected to the seat bucket 18 through the rotating shaft. The seat cushion rotates substantially around the axis of the rotating shaft, and the seat bucket 18 can be opened and closed by rotating the seat cushion.

[0076] The power supply unit 17 of the electric motorcycle 100 includes a first battery 171 and a second battery 172, both of which are used to provide electrical energy to the electric motorcycle 100. Figure 11As shown, the seat bucket 18 includes a box 181, which is a cylindrical structure with one end open. The box 181 has an accommodating space inside, which is located under the seat cushion and can be covered by the seat cushion. The accommodating space includes a first chamber 1811 for accommodating a first battery 171 and a second chamber 1812 for accommodating a second battery 172. Both the first battery 171 and the second battery 172 can provide energy to the motor assembly of the electric motorcycle 100 to drive the front wheel and / or rear wheel of the electric motorcycle 100 to rotate. The upper part of the first battery 171 and the second battery 172 respectively has a first wiring portion 1711 and a second wiring portion 1721 for electrical connection with the motorcycle. The first wiring portion 1711 and the second wiring portion 1721 are located at one end of the housing opening. The first wiring portion 1711 and the second wiring portion 1721 are located on the upper surface of the first battery 171 and the second battery 172 respectively and are arranged facing each other, that is, the first wiring portion 1711 and the second wiring portion 1721 are close to each other, thereby shortening the length of the connecting wire connecting the first wiring portion 1711 and the second wiring portion 172 and reducing the wiring harness layout. The first chamber 1811 and the second chamber 1812 are arranged in a stepped manner. This allows the first battery 171 and the second battery 172 to be arranged at different heights, thereby lowering the center of gravity of the motorcycle and improving the overall handling of the vehicle. At the same time, the staggered arrangement of the first battery 171 and the second battery 172 ensures that the first wiring section 1711 and the second wiring section 1721 are also located at different heights. This arrangement reduces the volume occupied by the charging plug and provides more operating space for the battery wiring harness connection.

[0077] Furthermore, in the forward direction of the electric motorcycle 100, the first chamber 1811 and the second chamber 1812 are arranged sequentially. Along the height direction of the electric motorcycle 100, the bottom surface of the first chamber 1811 is lower than the bottom surface of the second chamber 1812, thus the center of gravity of the first chamber 1811 is lower than that of the second chamber 1812 in the height direction of the electric motorcycle 100. During assembly, the first chamber 1811 is closer to the front of the vehicle; therefore, it can be assembled in a lower position. Simultaneously, the rider is typically positioned in a seated position above the first chamber 1811 during riding, and this arrangement further facilitates lowering the motorcycle's center of gravity.

[0078] To facilitate vehicle installation and subsequent maintenance, the wiring terminals of the first battery 171 and the second battery 172 are located on the open side of the seat bucket 18, which makes it easier for the driver and passengers to connect the wiring harness and also facilitates later battery testing.

[0079] In another embodiment of this application, the first chamber 1811 and the second chamber 1812 are configured such that after the first battery 171 and the second battery 172 are assembled, the first wiring portion 1711 and the second wiring portion 1721 are arranged alternately. That is, in the forward direction of the vehicle, after assembly, the first wiring portion 1711 is close to the rear of the vehicle, and the second wiring portion 1721 is close to the front of the vehicle. That is, the rear side of the first battery 171 and the front side of the second battery 172 are arranged opposite each other, so that during the wiring process of the first battery 171 and the second battery 172, the first wiring portion 1711 and the second wiring portion 1721 are arranged alternately in both the height and width directions of the vehicle. This makes the wiring harnesses connected to the first battery 171 and the second battery 172 staggered. This arrangement is beneficial to improving the space utilization rate and at the same time, it can avoid the problem of dense wiring harnesses.

[0080] Specifically, the first battery 171 and the second battery 172 are of the same model. During installation, the first battery 171 and the second battery 172 are installed at opposite angles. That is, after the first battery 171 is installed, the installation angle of the second battery 172 is 180 degrees different from that of the first battery 172, thus achieving an alternating arrangement of the first battery 171 and the second battery 172. Using battery packs of the same model facilitates mass production and processing in the factory, and is beneficial for cost control and maintenance.

[0081] like Figure 12 As shown, the accommodating space also includes a third chamber 1813, which is located behind the second chamber 1812. The first chamber 1811, the second chamber 1812, and the third chamber 1813 are arranged in a stepped manner. Since the third chamber 1813 is located at the rear of the electric motorcycle 100, its volume is smaller than that of the first chamber 1811 and the second chamber 1812. The third chamber 1813 is used to store small items, such as chargers or other items. Preferably, the bottom of the third chamber 1813 is also provided with a charger positioning groove, which facilitates the placement of the rechargeable battery and avoids the tangled wiring caused by the random placement of the rechargeable battery. The bottom sides of the third chamber 1813 are provided with a first protrusion 1813a and a second protrusion 1813b protruding inward from the side wall of the seat 18. The first protrusion 1813a and the second protrusion 1813b are symmetrically arranged, thereby forming a charger positioning groove between the first protrusion 1813a and the second protrusion 1813b.

[0082] The bottom of the seat compartment 18 is also provided with a drainage hole 1814 to prevent water from accumulating at the bottom of the seat compartment 18 and affecting the safety of battery use. The bottom of the first chamber 1811 and / or the second chamber 1812 is also provided with a battery positioning groove to facilitate battery positioning during battery placement. At the same time, the battery positioning groove can also improve the stability of the battery during vehicle operation.

[0083] To further facilitate battery assembly and positioning, ribs 1815 are formed on the inner wall of the housing 181 to separate the first chamber 1811 and the second chamber 1812; preferably, the height of the ribs 1815 is lower than the height of the battery to avoid the ribs 1815 occupying the operating space on the top of the battery.

[0084] Furthermore, a battery detection port or wire harness through hole is provided on the side wall of the first chamber 1811 away from the second chamber 1812 to facilitate the installation and use of the first battery 171 and the second battery 172.

[0085] Optionally, the first chamber 1811 and the second chamber 1812 are square cylindrical compartments, and the corresponding first battery 171 and second battery 172 are square cylindrical batteries. The stepped space design allows the weight of the batteries to be controlled between 8 and 12 kg. The configuration is reasonable and facilitates assembly and maintenance during use. The battery capacity of the corresponding volume is suitable for the mileage requirements of electric vehicles for commuting and also conforms to the layout of the vehicle's internal space. At the same time, the third chamber 1813 is used as a small storage box to facilitate the storage of small tools.

[0086] It is foreseeable that the electric motorcycle 100 provided in this application, by arranging the first chamber 1811, the second chamber 1812 and the third chamber 1813 in a stepped manner, can enable the seat bucket 18 to achieve an anti-slip connection with the mounting surface during installation, which greatly improves the stability of installation. Furthermore, the upper surfaces of the first battery 171 and the second battery 172 are not on the same plane, making the battery layers distinct and facilitating the insertion and removal of the batteries. The staggered arrangement of the wiring terminals of the first battery 171 and the second battery 172 helps to reduce the volume occupied by the wiring harness plug, improve space utilization, and reduce the risk of fire accidents.

[0087] like Figure 13As shown, the electric motorcycle 100 of this application also includes an electrical system 16, which includes at least one handlebar switch 161 and an electronic display screen 162. The handlebar switch 161 is sleeved on the outside of the handlebars, and the electronic display screen 162 is supported by the frame 11 between the left handlebar 151 and the right handlebar 152. The handlebar switch 161 includes a switch body 1611, in which a rocker arm 1612 and a PCB board are installed. The rocker arm 1612 has at least five degrees of freedom of movement in five directions: up, down, left, right, and center. The PCB board captures and provides feedback on the movement direction of the rocker arm 1612.

[0088] In use, the rider controls the movement of the joystick 1612. The joystick 1612 has five degrees of freedom of movement in five directions: up, down, left, right, and center. When the joystick 1612 moves in different directions, it applies pressure to the PCB board from different directions, causing the PCB board to make different functional feedbacks according to the direction of pressure, thereby realizing the control of different functions. Multiple functions are integrated into the joystick 1612, which can control multiple functions. The number of buttons is reduced, which can effectively save handle space, facilitate operation, and reduce the occurrence of misoperation.

[0089] Figure 14 The following is a logic block diagram of the operation control of the electric motorcycle 100 in this application, as shown: Figure 14 As shown, during the use of the electric motorcycle 100, firstly, in step S01, the electric motorcycle is started. After the electric motorcycle 100 is started, the electrical system 16 of the electric motorcycle 100 is connected to the power supply, and the first battery 171 or the second battery 172 supplies power to the electrical system 16. After completing the above step S01, in step S02, the driving speed of the electric motorcycle 100 is obtained, wherein the driving speed can be obtained by a speed sensor installed on the front wheel or the rear wheel of the electric motorcycle 100. After obtaining the driving speed of the electric motorcycle 100, in step S03, the operating mode of the electric motorcycle 100 is determined based on the driving speed of the electric motorcycle 100, wherein the operating mode includes a first operating mode and a second operating mode.

[0090] Specifically, the electric motorcycle 100 has a first operating mode and a second operating mode. When the speed of the electric motorcycle 100 is greater than zero, the electric motorcycle enters the first operating mode, and when the speed of the electric motorcycle 100 is equal to zero, the electric motorcycle enters the second operating mode.

[0091] In the first operating mode, the entertainment images displayed on the electronic display screen do not change in response to the movement of the joystick 1612. In the second operating mode, the entertainment images displayed on the electronic display screen can change in response to the movement of the joystick 1612. This prevents the user from accessing the entertainment interface while the motorcycle is in motion, thus affecting driving safety.

[0092] Furthermore, the entertainment image specifically refers to an image used to represent at least the entertainment function in operation and / or capable of supporting the entertainment function to be operated; wherein the entertainment function includes at least one of the following: navigation function, multimedia function, driver assistance function, voice control function, connectivity function, and gaming function; thereby, while the vehicle is parked, the driver and passengers can also operate the game by operating the joystick 1612, which helps to alleviate the tension that may occur during the driving process.

[0093] When the entertainment function is for gaming, the electronic display screen 162 is used to display game image information, and the handlebar switch 161 located on the outside of the motorcycle handlebars is configured as an input device for the game to control objects in the game. The display interface of the electronic display screen can respond to the movement of the joystick 1612, so that the rider can more intuitively understand the operation function and operation process corresponding to each direction of the joystick 1612.

[0094] The handlebar switch 161 includes a left handlebar switch mounted on the left handlebar and a right handlebar switch mounted on the right handlebar. When the handlebar switch 161 is configured as an input device for a game, one of the left and right handlebar switches is used for position control of the target object, and the other is used for function control of the target object. For example, the left handlebar switch can be used as a directional key for game operation to control the movement of objects in the game; the right handlebar switch 161 can be used as an AB key to control the function operation of objects in the game.

[0095] Electrical system 16 may also include a storage unit for storing applications used to generate entertainment images.

[0096] It is foreseeable that the control unit of the electric motorcycle 100 provided in this application stores game applications, and by using the electronic display screen as the image information output device for the game and the handlebar switch 161 located on the outside of the motorcycle handlebars as the input device for the game, the entertainment performance of the vehicle is increased, which helps to relieve the tension of the driver and passengers during parking and can meet people's different needs for the vehicle.

[0097] Furthermore, a disc 1614 can be installed on the top of the joystick 1612. Pressing the disc 1614 drives the joystick 1612 to move in five directions: up, down, left, right, and center. The joystick 1612 can be operated through the disc 1614, making operation more convenient.

[0098] In another embodiment, the disc 1614 may be spherical or button-shaped, which facilitates pushing or pressing operations. Preferably, the upper surface of the disc 1614 may also be provided with an arc-shaped groove to facilitate pressing by the operator's fingers. At the same time, the arc-shaped groove can also be used to install optional decorative parts to improve the aesthetics of the vehicle's exterior.

[0099] Optionally, at least one set of push-button switches may also be installed on the switch body 1611 to realize other auxiliary functions. The push-button switches may be, for example, turn signals, horn switches, dimmer switches, cruise switches, start switches, lighting switches, engine kill switches, or warning switches.

[0100] To facilitate operation and enhance the enjoyment of use, the handle switch 161 also features a backlight function. Specifically, the joystick 1612 of the handle switch 161 has a backlight function. The handle switch 161 includes a PCB board with a light source, such as an LED light source. The light emitted by the light source illuminates the inner surface of the joystick 1612 and the switch body 1611, allowing the driver or passenger to clearly see the patterns or text on the switch body 1611 and the joystick 1612.

[0101] In another embodiment, the electronic display screen 162 can also be used to display entertainment images, wherein the entertainment images specifically refer to images that at least characterize an entertainment function in operation and / or can support an entertainment function to be operated.

[0102] To facilitate the assembly of the switch body 1611, a clearance opening is provided on the side of the switch body 1611 facing the rocker arm 1612 for the rocker arm 1612 to pass through, thereby making it easier to assemble and maintain the rocker arm 1612. The clearance opening can be circular, square, or other shapes. Additionally, an arc-shaped guide surface can be provided on the inner side of the clearance opening.

[0103] It is foreseeable that the motorcycle in this application can control different functions by setting a joystick 1612 with five degrees of freedom of movement in five directions: up, down, left, right, and center. Multiple functions are integrated on the joystick 1612, and multiple functions can be controlled through the joystick 1612. The number of buttons is reduced, which can effectively save handlebar space, facilitate operation, and reduce the occurrence of misoperation.

[0104] In another embodiment of this application, such as Figure 15As shown, a removable decorative panel is installed on the switch body 1611. The decorative panel can be, for example, a cover plate 1613. After the surface of the switch body 1611 wears down due to long-term use, the external appearance of the switch body 1611 can be maintained by replacing the cover plate 1613, avoiding the need to replace the entire switch body 1611. This improves the service life of the switch body 1611 and reduces the cost of later maintenance. At the same time, the cover plate 1613 can also be different colors, so by replacing the cover plate 1613 with different colors, the switch body 1611 with different appearance colors can be obtained, which can further improve the aesthetics of the electric motorcycle 100 and meet people's personalized needs.

[0105] Specifically, such as Figure 15 As shown, the handlebar switch 161 with cover plate 1613 provided in this application includes a switch body 1611, the switch body 1611 has a mounting hole, the switch body 1611 can be sleeved on the outside of the handlebar of a motorcycle through the mounting hole, and at least one switch is provided on the outer surface of the switch body 1611. The switch body 1611 also includes a cover plate 1613, the cover plate 1613 is detachably disposed on the outer surface of the switch body 1611, and the cover plate 1613 has a clearance opening for the switch to pass through.

[0106] The switch can be a rocker switch (1612 type), a push-button switch, or a slide switch.

[0107] like Figure 15 As shown, a groove 1611a is provided on the switch body 1611, and the cover plate 1613 can be inserted into the groove 1611a, so that the outer surface of the switch body 1611 has a smooth surface after the cover plate 1613 is installed. In order to facilitate the disassembly of the cover plate 1613, an opening notch or opening bevel is provided on the edge of the groove, so that the cover plate 1613 can be easily lifted when replacing it.

[0108] Furthermore, the switch body 1611 may have multiple surfaces in the circumferential direction of the handlebar, and the switch may be disposed on one or more surfaces of the switch body 1611. When the switch is disposed on different surfaces, multiple covers 1613 may be provided, and the multiple covers 1613 may have different shapes and colors to meet the personalized needs of users.

[0109] To facilitate the fixing of the cover plate 1613, the cover plate 1613 and the switch body 1611 can be fixed by a snap-fit ​​structure or a magnetic attraction structure. Specifically, for example... Figure 16 , Figure 17As shown, the cover plate 1613 is provided with a first limiting part 1613a and a locking part 1613b, and the switch body 1611 is provided with a second limiting part 1611b that can be positioned and engaged with the first limiting part 1613a and a locking part 1611c that can be engaged with the locking part 1613b. The first limiting part 1613a may be, for example, a positioning protrusion, the second limiting part 1611b may be, for example, a positioning groove, the locking part 1613b may be, for example, a buckle, and the locking part 1611c may be, for example, a snap-fit ​​opening that engages with the buckle.

[0110] During use, the positioning protrusion on the cover plate 1613 first inserts into the positioning groove on the switch body 1611 to fix the cover plate 1613 on one side. Then, the buckle on the cover plate 1613 elastically snaps into the snap-fit ​​opening on the switch body 1611 to fix the cover plate 1613.

[0111] In another embodiment, the cover plate 1613 is provided with a magnet mounting slot for fixing the magnet on the side facing the switch body 1611. The switch body 1611 is equipped with a magnetic material, so that the cover plate 1613 is fixedly fitted by the magnetic attraction between the magnetic material inside the switch body 1611 and the magnet.

[0112] It is foreseeable that the motorcycle provided in this application has a removable cover plate 1613 on the shell, so that after the surface of the shell is worn due to long-term use, the exterior of the shell can be maintained by replacing the cover plate 1613, avoiding the need to replace the entire shell, thereby improving the service life of the shell and reducing the cost of later maintenance. At the same time, the cover plate 1613 can also be different colors, and by replacing the cover plate 1613 of different colors, shells with different appearance colors can be obtained, which can further improve the aesthetics of the electric motorcycle 100 and meet people's personalized needs.
