Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to an electric motorcycle. Background Technology

[0002] With the increasing number of cars, traffic congestion is becoming more and more severe during commutes and holidays. In contrast, electric motorcycles are becoming increasingly popular for short-distance travel because they are convenient, fast, and unaffected by traffic jams.

[0003] Electric motorcycles are a type of electric vehicle that uses batteries to drive a motor, converting electrical energy into mechanical energy for traction, thus ensuring the motorcycle's normal operation. Current electric motorcycles consist of a frame assembly and a battery pack. The frame assembly is a single, integrated unit, and the battery pack is connected to the frame assembly.

[0004] However, adopting the above structure results in a heavier overall vehicle weight, and the installation position of the battery pack is limited by the frame assembly structure. This leads to instability in the electric motorcycle during operation, affecting safety and handling. Summary of the Invention

[0005] In view of this, and to address the aforementioned technical problems, it is necessary to provide an electric motorcycle that offers greater stability, safety, and ease of operation.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] An electric motorcycle includes: a frame assembly; a suspension assembly; a body panel at least partially connected to the frame assembly; a wheel assembly at least partially connected to the frame assembly via the suspension assembly; and a battery assembly at least partially connected to the frame assembly.

[0012] Furthermore, L2 / L1 is greater than 0.4 and less than or equal to 0.6, and the angle between the centerline of the shock absorber and the length direction of the electric motorcycle is greater than 50° and less than or equal to 65°.

[0013] Furthermore, the electric motorcycle also includes: a fastener, which passes through the battery device and the end of the shock absorber near the battery device, and the shock absorber is connected to the battery device; a shock absorber, which is located between the battery device and the fastener, and is fitted onto part of the fastener; wherein, as the fastener is tightened, the fastener can press tightly onto the shock absorber to cause the shock absorber to deform.

[0014] Furthermore, one end of the rear swingarm is connected to the rear wheel, and the end of the rear swingarm away from the rear wheel is connected to the battery device; the electric motorcycle also includes a drive unit connected to the rear swingarm.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] In the following description, the forward and backward directions and the left and right directions correspond to directions based on the rider's perspective, and the descriptions of the forward, backward, left, right, up, and down directions are as follows: Figure 1 The direction shown.

[0035] Please see Figure 1 and Figure 2 An electric motorcycle 100 includes a frame assembly 10, a body panel 20, a suspension assembly 30, a wheel assembly 40, a battery device 50, a drive unit 60, an electronic control device 70, and a charging device 80. The body panel 20 is at least partially connected to the frame assembly 10, the wheel assembly 40 is at least partially connected to the frame assembly 10 via the suspension assembly 30, and the battery device 50 is at least partially connected to the frame assembly 10.

[0036] The vehicle frame assembly 10 includes a front frame 11 and a rear frame 12. The front frame 11 includes a first branch pipe 111, a second branch pipe 112, and a third branch pipe 113. The first branch pipe 111 and the second branch pipe 112 are spaced apart, and the third branch pipe 113 is located between the first branch pipe 111 and the second branch pipe 112, with both ends of the third branch pipe 113 connected to the first branch pipe 111 and the second branch pipe 112, respectively. Both the first branch pipe 111 and the second branch pipe 112 are connected to the battery unit 50. Specifically, the first branch pipe 111 is connected to the upper end of the battery unit 50, and the second branch pipe 112 is connected to the front side of the battery unit 50.

[0037] The rear frame 12 includes a fourth branch tube 121, a fifth branch tube 122, and a sixth branch tube 123. One end of the fourth branch tube 121 is connected to the battery device 50, and one end of the fifth branch tube 122 is connected to the battery device 50. The ends of the fourth branch tube 121 and the fifth branch tube 122 away from the battery device 50 are connected to each other. The sixth branch tube 123 is located between the fourth branch tube 121 and the fifth branch tube 122, and both ends of the sixth branch tube 123 are connected to the fourth branch tube 121 and the fifth branch tube 122, respectively.

[0038] Specifically, the fourth branch pipe 121 is connected to the upper end of the battery device 50, and the fifth branch pipe 122 is connected to the rear side of the battery device 50.

[0039] Of course, in other embodiments, the connection positions and relationships of each branch pipe can also be changed according to actual needs, as long as the same effect is achieved.

[0040] The battery unit 50 provides power to the electronic control unit 70 and the drive unit 60. The electronic control unit 70 controls the drive unit 60 to operate, thereby driving the wheel assembly 40 to rotate. The charging unit 80 is connected to the public power grid via wires, thereby converting the alternating current (AC) from the public power grid into direct current (DC) to charge the battery unit 50.

[0041] In this embodiment, the battery device 50 is located between the front frame 11 and the rear frame 12, and is connected to both the front frame 11 and the rear frame 12. By placing the battery device 50 between the front frame 11 and the rear frame 12, the battery device 50 can be considered as part of the frame assembly 10, serving a supporting function and bearing the indirect or direct mounting of most components on the electric motorcycle 100. Furthermore, it saves the original frame, thereby reducing the overall weight of the vehicle. At the same time, it simplifies the installation and arrangement of the battery device 50, avoiding the limitations imposed by the structure of the frame assembly 10 as in existing designs.

[0042] Please see Figure 3 The wheel assembly 40 includes a front wheel 41 and a rear wheel 42. The distance between the axle of the front wheel 41 and the axle of the rear wheel 42 is defined as the wheelbase of the electric motorcycle 100, which is L1. The vertical distance from the centerline of the battery device 50 in the longitudinal direction to the axle of the front wheel 41 is L2. L2 / L1 is greater than or equal to 0.25 and less than or equal to 0.6. By reasonably arranging the position of the battery device 50, interference between the battery device 50 and the front wheel 41, the rear suspension unit 31, and the rear wheel 42 can be avoided. Furthermore, the center of gravity of the electric motorcycle 100 can be concentrated near the front wheel 41, making the electric motorcycle 100 more stable, safer, and more maneuverable during driving, and improving the overall operating efficiency.

[0043] It should be noted that, based on the rider's perspective, the front side of the battery device 50 is the side of the battery device 50 closest to the front wheel 41, and the rear side of the battery device 50 is the side of the battery device 50 closest to the rear wheel 42.

[0044] Please see Figure 1 The suspension assembly 30 includes a rear suspension unit 31, one end of which is connected to the rear wheel 42, and the other end of which is connected to the battery device 50. If the battery device 50 is installed too close to the rear wheel 42, the stiffness requirement for the rear suspension unit 31 will be extremely high, and the center of gravity of the electric motorcycle 100 will shift rearward. In this case, the efficiency of the electric motorcycle 100 during driving will be greatly reduced. Therefore, by setting the battery device 50 slightly closer to the front wheel 41, the center of gravity of the electric motorcycle 100 can be concentrated at a position closer to the front wheel 41, making the electric motorcycle 100 more stable during driving, with better safety and handling, and higher overall vehicle operating efficiency.

[0045] Please see Figure 3The rear suspension unit 31 includes a shock absorber 311 and a rear swingarm 312. One end of the shock absorber 311 is connected to the rear swingarm 312, and the other end of the shock absorber 311 is connected to the battery device 50. The shock absorber 311 mainly plays a buffering role, mitigating and damping the vibrations and impacts caused by uneven road surfaces during the operation of the electric motorcycle 100, ensuring a smooth and comfortable ride, and improving the lifespan and stability of the electric motorcycle 100.

[0046] The shock absorber 311 is inclined and is mounted at an angle between the battery unit 50 and the rear swingarm 312. This inclined arrangement increases the damping stroke, resulting in better damping performance. Furthermore, the shock absorber 311 controls the load transfer rate from the rear wheel 42 to the front wheel 41, and the inclined arrangement of the shock absorber 311 improves the grip of the wheel assembly 40.

[0047] By rationally arranging the position of the battery device 50, so that the battery device 50 is as close as possible to the front wheel 41, there is also enough space to arrange the shock absorber 311 at an angle, thereby improving the shock absorption effect of the shock absorber 311.

[0048] Please see Figure 4 The centerline of the shock absorber 311 is set at an angle A with the length direction of the electric motorcycle 100. A is greater than or equal to 0° and less than or equal to 65°. If angle A is greater than 65°, the shock absorption effect of the shock absorber 311 will be reduced, decreasing the stability of the electric motorcycle 100 during operation.

[0049] Preferably, angle A is greater than or equal to 25° and less than or equal to 65°. If angle A is less than 25°, it may increase the length of the electric motorcycle 100; if angle A is greater than 65°, it will reduce the shock absorption effect of the shock absorber 311 and reduce the stability of the electric motorcycle 100 during operation. Therefore, it is preferable to set angle A to be greater than or equal to 25° and less than or equal to 65°, so that the shock absorber 311 can achieve the best shock absorption effect. For example, A can be 30°, 45°, or 60°.

[0050] Preferably, L2 / L1 is greater than or equal to 0.25 and less than or equal to 0.4, and A is greater than or equal to 25° and less than or equal to 50°.

[0051] As a result, the angle of the rear swingarm 312 is lowered, the leverage ratio of the rear suspension unit 31 is increased, the overall posture of the vehicle is more sporty, and the acceleration performance of the electric motorcycle 100 is improved, the cornering roll limit of the electric motorcycle 100 is improved, and the handling performance of the electric motorcycle 100 is improved.

[0052] Preferably, L2 / L1 is greater than 0.4 and less than or equal to 0.6, and A is greater than 50° and less than or equal to 65°.

[0053] As a result, the rear swingarm 312 angle is adjusted upwards, the lever ratio of the rear suspension unit 31 is reduced, the overall posture of the vehicle is more comfortable, and the electric motorcycle 100 moves more smoothly when encountering road bumps, thereby improving the driving comfort of the electric motorcycle 100.

[0054] Please see Figure 5 and Figure 6 The electric motorcycle 100 also includes a fastener 13, which can pass through the battery device 50 and the shock absorber 311 near the end of the battery device 50, and securely connect the shock absorber 311 to the battery device 50.

[0055] The electric motorcycle 100 also includes a shock absorber 15, which is fitted onto a portion of the fastener 13 and located between the battery device 50 and the fastener 13. Since the shock absorber 311 and the fastener 13, and the fastener 13 and the battery device 50, are all clearance fit, the shock absorber 15 is provided. Firstly, when the electric motorcycle 100 is in motion, the shock absorber 311 will vibrate. By providing the shock absorber 15, it can absorb some of the vibration, allowing the shock absorber 311 to maintain a relatively stable state, thereby improving the shock absorption effect and the stability of the connection between the shock absorber 311 and the battery device 50. Secondly, the shock absorber 15 can generate a certain amount of deformation, thereby eliminating clearance errors and making the connection between the shock absorber 311, the fastener 13, and the battery device 50 more stable, improving the shock absorption effect and service life.

[0056] The shock absorber 15 is a wave spring with a certain deformation. The wave spring has a good vibration absorption effect and can eliminate gap errors and height tolerances. Of course, in other embodiments, components with the same function can be used instead of the wave spring; this is not limited, as long as the same effect can be achieved.

[0057] Please see Figure 3 and Figure 6 The battery device 50 includes a connecting unit 51, which is located on the rear side of the battery device 50, that is, on the side of the battery device 50 near the rear wheel 42, and the connecting unit 51 has a connecting hole 511. The fastener 13 can pass through the end of the shock absorber 311 near the battery device 50 and the connecting hole 511, and securely connect the shock absorber 311 to the battery device 50.

[0058] The damping element 15 is located between the connecting unit 51 and the fastener 13. Specifically, the damping element 15 is located on the side of the connecting unit 51, and with the installation of the fastener 13, the fastener 13 can abut against and press tightly against the damping element 15. This allows the damping element 15 to absorb some vibration, improve the damping effect, and also allows the damping element 15 to produce a certain deformation to compensate for gap errors, making the connection between the fastener 13, the connecting unit 51, and the damper 311 more compact and tight, and improving the stability of the connection between the damper 311 and the battery device 50.

[0059] The waveform reed is roughly annular in shape, specifically a square ring, and its sides are not on the same plane. It should be noted that the sides of the waveform reed refer to the sides closest to or furthest from the connecting unit 51. Both sides of the waveform reed are corrugated surfaces, meaning that both the sides closest to and furthest from the connecting unit 51 are corrugated surfaces, which facilitates the deformation of the waveform reed to compensate for gap errors, etc.

[0060] Please see Figure 5 and Figure 6 The fastener 13 includes a stop portion 131, which is located at one end of the fastener 13. One end of the fastener 13 abuts against the connecting unit 51 via the stop portion 131, and the end of the fastener 13 away from the stop portion 131 passes through the connecting unit 51 and the shock absorber 311, thus tightly connecting the shock absorber 311 to the battery device 50. The stop portion 131 also serves as a limit, controlling the insertion distance of the fastener 13 and facilitating quick installation of the fastener 13.

[0061] In one embodiment, the shock absorber 15 is located between the connecting unit 51 and the abutment 131. By locking the fastener 13, the connecting unit 51 and the abutment 131 can compress the shock absorber 15, causing the shock absorber 15 to produce a certain deformation. This can eliminate the gap error between the connecting unit 51, the shock absorber 311, and the fastener 13, making the connection between the shock absorber 311, the fastener 13, and the connecting unit 51 more stable, thereby improving the shock absorption effect and service life.

[0062] Please refer to the figure. The connecting unit 51 includes a first connecting portion 52 and a second connecting portion 53. The first connecting portion 52 and the second connecting portion 53 are spaced apart. The first connecting portion 52 has a first connecting hole 521, and the second connecting portion 53 has a second connecting hole 531. The axes of the first connecting hole 521 and the second connecting hole 531 coincide.

[0063] The end of the shock absorber 311 near the battery device 50 can extend between the first connecting part 52 and the second connecting part 53. The fastener 13 passes through the first connecting hole 521, the shock absorber 311 and the second connecting hole 531, and locks the shock absorber 311 and the connecting unit 51.

[0064] Specifically, the shock absorber 15 is located between the first connecting portion 52 and the abutting portion 131. As the fastener 13 passes through the first connecting hole 521, the shock absorber 311 and the second connecting hole 531, the abutting portion 131 abuts against and presses against the shock absorber 15.

[0065] Please continue reading. Figure 5 and Figure 6 The shock absorber 311 includes an extension portion 3111 that extends between the first connecting portion 52 and the second connecting portion 53. The fastener 13 passes through the first connecting portion 52, the extension portion 3111 and the second connecting portion 53, and locks the shock absorber 311 and the connecting unit 51.

[0066] The electric motorcycle 100 also includes a mating sleeve 14, one end of which extends into the second connecting hole 531, and the other end of which abuts against the second connecting portion 53. A fastener 13 passes through the mating sleeve 14, and both sides of the protruding portion 3111 abut against the mating sleeve 14 and the fastener 13, respectively. The mating sleeve 14 prevents wear and tear, and allows for faster and smoother assembly of the fastener 13.

[0067] The mating sleeve 14 includes a mounting portion 141 and an abutting portion 142, with one end of the mounting portion 141 connected to the abutting portion 142. The mounting portion 141 extends into the second connecting hole 531, and the abutting portion 142 is located outside the second connecting hole 531, and is located on the side of the second connecting portion 53 closer to the first connecting portion 52, abutting against the second connecting portion 53. The two sides of the extending portion 3111 respectively abut against the abutting portion 142 and the fastener 13.

[0068] In this embodiment, the mating sleeve 14 is a bushing. Of course, in other embodiments, the mating sleeve 14 can also be other components, as long as they can achieve the same effect.

[0069] The fastener 13 includes a fastening unit 132 and a mating unit 133. One end of the mating unit 133 passes through the connecting unit 51 and the shock absorber 311, and the other end of the mating unit 133 abuts against the connecting unit 51. The fastening unit 132 is sleeved on part of the mating unit 133, and the fastening unit 132 locks the shock absorber 311 and the connecting unit 51 by cooperating with the mating unit 133.

[0070] Specifically, the abutment part 131 is provided on the mating unit 133, and the mating unit 133 has a first connecting hole 521, a shock absorber 311 and a second connecting hole 531 passing through it. The abutment part 131 abuts against the shock absorber 15. The fastening unit 132 is located on the side of the second connecting part 53 away from the first connecting part 52. The fastening unit 132 is sleeved on the mating unit 133 and is locked by cooperating with the mating unit 133.

[0071] The mating unit 133 includes a first mating section 1331 and a second mating section 1332, which are connected. An abutment portion 131 is disposed on the first mating section 1331, a shock absorber 15 is sleeved on the first mating section 1331, and a fastening unit 132 is sleeved on the second mating section 1332. The second mating section 1332 passes through the shock absorber 311 and the second connecting hole 531. The first mating section 1331 is located at the end of the second mating section 1332 furthest from the second connecting hole 531 and is connected to the second mating section 1332. The first mating section 1331 passes through the first connecting hole 521.

[0072] In one embodiment, the diameter of the first mating section 1331 is larger than the diameter of the second mating section 1332. A step 1333 is formed between the first mating section 1331 and the second mating section 1332. One side of the extension portion 3111 abuts against the second connecting portion 53, and the other side of the extension portion 3111 abuts against the step 1333. The step 1333 serves two purposes: firstly, it facilitates the limiting of the extension portion 3111, ensuring that the first mating section 1331 is tightly abutted against the side of the extension portion 3111, thus improving the connection's strength; secondly, it facilitates the rapid installation of the fastener 13. By controlling the distance the fastener 13 penetrates through the step 1333, it reminds the operator to ensure proper installation before locking with the fastening unit 132, making the operation simple and convenient. Furthermore, it also helps prevent wear on the connecting unit 51 caused by a tight connection between the extension portion 3111 and the connecting unit 51, reducing costs. The cost of replacing the battery device 50 if the connecting unit 51 is worn is much higher than the cost of replacing the fastener 13 if the fastener 13 is worn.

[0073] At the same time, due to the setting of step 1333, there will also be gap error between fastener 13, shock absorber 311 and connecting unit 51. At this time, the setting of shock absorber 15 can also eliminate gap error, making the structure more compact and enhancing the firmness of the connection.

[0074] In another embodiment, one side of the insertion portion 3111 abuts against the mating sleeve 14, and the other side of the insertion portion 3111 abuts against the step 1333, thereby making the structure more compact and enhancing the strength of the connection.

[0075] Fastener 13 includes bolts and nuts for easy connection and disassembly. Specifically, fastening unit 132 is a nut and mating unit 133 is a bolt. Of course, fastening unit 132 and mating unit 133 can also be other components with the same function, which is not limited here.

[0076] Please see Figure 5 The end of the shock absorber 311 connected to the rear horizontal fork 312 is also connected by fastener 13, shock absorber 15 and mating sleeve 14. The specific connection structure and connection method will not be described in detail here.

[0077] Please see Figure 3 In one embodiment, one end of the rear swingarm 312 is connected to the rear wheel 42, and the end of the rear swingarm 312 away from the rear wheel 42 is connected to the battery device 50.

[0078] The drive unit 60 is connected to the rear swingarm 312. This ensures that the center distance of the drive unit 60 remains constant during the operation of the electric motorcycle 100, thereby improving transmission efficiency and effectively reducing noise.

[0079] Furthermore, the drive unit 60 is located at the end of the rear swingarm 312 near the battery unit 50 and is connected to the rear swingarm 312. Because the front end of the rear swingarm 312 is connected to the battery unit 50, it offers high stability. The drive unit 60's connection to the rear swingarm 312 near the battery unit 50 significantly reduces the vibration amplitude of the drive unit 60, improving the overall vehicle stability. Moreover, by rationally arranging the drive unit 60, the battery unit 50, drive unit 60, and rear swingarm 312 are integrated, resulting in a more compact structure. This significantly saves space within the limited space of the vehicle, achieving weight reduction for the electric motorcycle 100 and lowering overall vehicle costs. Simultaneously, the rational placement effectively reduces the length of the wiring harness, thereby improving electrical performance. It should be noted that the front end of the rear swingarm 312 refers to the end of the rear swingarm 312 closest to the front wheel 41.

[0080] In another embodiment, the drive unit 60 is connected to the battery unit 50, one end of the rear swingarm 312 is connected to the drive unit 60, and the other end of the rear swingarm 312 is connected to the rear wheel 42.

[0081] Specifically, the drive unit 60 is located near the rear of the battery unit 50 and is connected to the battery unit 50. The drive unit 60 includes a drive shaft, and the rear swingarm 312 is connected to the drive shaft of the drive unit 60. Further, the rear swingarm 312 includes a connection point, which is connected to the drive shaft, thereby connecting the rear swingarm 312 to the drive unit 60. The drive shaft of the drive unit 60 and the connection point of the rear swingarm 312 are coaxially arranged, and the connection point of the rear swingarm 312 has the highest stability, thus reducing the vibration amplitude of the drive unit 60. Simultaneously, connecting the rear swingarm 312 and the drive unit 60 through the battery unit 50 improves the overall structural stability.

[0082] In this embodiment, the driving device 60 is a drive motor. Of course, in other embodiments, the driving device 60 can be other components with the same function, and there is no limitation here.

[0083] Please see Figure 2 , Figure 3 as well as Figure 7 The electronic control device 70 is mounted on the battery device 50. Due to the reasonable arrangement of the battery device 50, the battery device 50 is regarded as part of the frame assembly 10 and plays a supporting role. The electronic control device 70 can be installed on the left, right, top, bottom, front or rear side of the battery device 50, and can be installed according to actual needs.

[0084] In one embodiment, both the electronic control device 70 and the charging device 80 are located at the upper end of the battery device 50.

[0085] Specifically, the electronic control device 70 is located at the upper end of the battery device 50. The charging device 80 is located on the side of the electronic control device 70 away from the battery device 50. That is, along the height direction of the electric motorcycle 100, the battery device 50, the electronic control device 70, and the charging device 80 are arranged sequentially. By reasonably arranging the positions of the battery device 50, the electronic control device 70, and the charging device 80, the structure can be made more compact, and the connecting cables between the components can be shorter, facilitating cable management. Of course, in other embodiments, the installation position of the charging device 80 can also be changed according to actual needs.

[0086] Please see Figures 7 to 9The electric motorcycle 100 also includes a connecting plate unit 16, which is located above the battery assembly 50. One end of the connecting plate unit 16 is connected to the front frame 11, and the other end of the connecting plate unit 16 away from the front frame 11 is connected to the rear frame 12. Specifically, the connecting plate unit 16 is located between the charging device 80 and the electronic control device 70. The charging device 80 is mounted on the connecting plate unit 16, located on the side of the connecting plate unit 16 away from the battery assembly 50, and connected to the connecting plate unit 16, that is, the charging device 80 is located above the connecting plate unit 16, and the connecting plate unit 16 supports the placement of the charging device 80.

[0087] In one embodiment, the electronic control device 70 is located between the connecting plate unit 16 and the battery device 50, that is, the electronic control device 70 is located below the connecting plate unit 16 and is connected to the battery device 50.

[0088] By providing the connecting plate unit 16, it serves two purposes: firstly, it provides support, offering an installation location for the charging device 80 so that it can connect to the connecting plate unit 16, and also provides installation space for components such as the charging device 80 and the electronic control device 70. Secondly, it enhances rigidity, as both ends of the connecting plate unit 16 are connected to the front frame 11 and the rear frame 12, respectively, thereby improving the strength of the entire frame assembly 10.

[0089] Of course, in other embodiments, the installation of the electronic control device 70 can be changed according to actual needs, such as the electronic control device 70 being located between the connecting plate unit 16 and the battery device 50, and the electronic control device 70 being connected to the connecting plate unit 16.

[0090] Please see Figure 7 and Figure 8 The connecting plate unit 16 includes a connecting pipe 161 and a connecting plate 162. The two ends of the connecting pipe 161 are connected to the front frame 11 and the rear frame 12, respectively. The connecting plate 162 is mounted on the connecting pipe 161, and the charging device 80 is mounted on the connecting plate 162.

[0091] The connecting pipe 161 is approximately Z-shaped to avoid the installation of the electronic control device 70 and prevent interference between the connecting plate unit 16 and the electronic control device 70. Of course, in other embodiments, the shape of the connecting pipe 161 can be changed according to actual needs, as long as the same effect can be achieved.

[0092] Please see Figure 7 and Figures 9 to 11The electric motorcycle 100 also includes a wiring trough 171, which is formed between the electronic control device 70 and the battery device 50. Optionally, the electric motorcycle 100 includes a wiring board 17, which is located between the battery device 50 and the electronic control device 70, and forms the wiring trough 171 and is connected to the battery device 50. The total wiring of the vehicle is arranged between the battery device 50 and the electronic control device 70, and the wiring board 17 can limit the total wiring. The total wiring can be confined within the wiring trough 171, avoiding messy wiring and improving neatness. At the same time, arranging the total wiring between the battery device 50 and the electronic control device 70 can also shorten the length of the total wiring, save materials, and reduce costs. The total wiring includes one or any combination of electronic control wiring harness, instrument wiring harness, taillight wiring harness, electrical component wiring harness, and ABS wiring harness.

[0093] The electric motorcycle 100 also includes a conversion module and a control module. The conversion module can be a DC-DC converter, and the control module can be a VCU (Vehicle Control Unit) or other electrical components. These components can be mounted on the left and right sides of the battery unit 50. Alternatively, other electrical components can be mounted or suspended on the sides of the battery unit 50. Furthermore, arranging all electrical components on the battery unit 50 facilitates the limiting of cable routing for each component, resulting in a neat overall cable layout and shorter cable lengths.

[0094] In one embodiment, the electronic control device 70 or the charging device 80 is located on one side of the battery device 50 in the left-right direction, and the DC-DC converter or VCU is located on the other side of the battery device 50 in the left-right direction.

[0095] Please refer to it again. Figure 1 The electric motorcycle 100 also includes a handlebar unit 90, which is at least partially connected to the frame assembly 10. The handlebar unit 90 is a one-piece structure, and its height is adjustable.

[0096] The arrangement and connection method of the battery device 50 and the frame assembly 10 in this application can also be applied to the scooter 200, and is not limited to the electric motorcycle 100.

[0097] Please see Figure 12 This application also provides a scooter 200, in which the forward and backward directions and the left and right directions correspond to directions based on the rider's perspective in the following description, and the forward, backward, left, right, up, and down directions are described as follows: Figure 12 The direction shown.

[0098] Please see Figure 12 The scooter 200 includes a frame unit 201, a cover, a wheel unit 204, a suspension unit 205, and a handlebar unit 206. The cover is at least partially connected to the frame unit 201, the wheel unit 204 is at least partially connected to the frame unit 201 via the suspension unit 205, and the handlebar unit 206 is at least partially connected to the frame unit 201.

[0099] In one embodiment, the frame unit 201 is an integral structure. The integrally formed frame unit 201 is easy to process and reduces assembly time.

[0100] In another embodiment, the frame unit 201 is a split structure, and the frame unit 201 includes a first frame and a second frame.

[0101] The cover includes a pedal unit located at the bottom of the vehicle and at least partially connected to the frame unit 201, facilitating the placement of the driver's feet and the placement of other items.

[0102] The scooter 200 also includes a battery unit 207, which is installed inside the scooter unit. The placement of the battery unit 207 inside the scooter unit allows for increased overall battery capacity due to the larger space within the scooter unit; furthermore, the scooter unit's location at the bottom of the vehicle lowers the center of gravity, thus improving overall handling.

[0103] The pedal unit has an installation space within it, and the battery unit 207 is installed within this space. The pedal unit includes a first pedal and a second pedal. The first pedal is located on the upper side of the frame unit 201 and connected to it; that is, the first pedal is located on the side of the frame unit 201 closest to the handlebar unit 206 and connected to it. The first pedal is used to support the rider's feet. The second pedal is located on the lower side of the frame unit 201 and connected to it; that is, the second pedal is located on the side of the frame unit 201 furthest from the handlebar unit 206 and connected to it. The second pedal is used to support the battery unit 207. The battery unit 207 is located between the first pedal and the second pedal.

[0104] One end of the suspension unit 205 is connected to the wheel unit 204, and the other end of the suspension unit 205 is connected to the frame unit 201. Specifically, the wheel unit 204 includes a rear wheel 2041, one end of the suspension unit 205 is connected to the rear wheel 2041, and the other end of the suspension unit 205 is connected to the frame unit 201.

[0105] The scooter 200 also includes a saddle and a helmet case 209. The saddle is mounted on the frame unit 201, and the helmet case 209 is located below the saddle and is at least partially connected to the frame unit 201. The rider opens or closes the saddle to retrieve or place the helmet. Specifically, the helmet case 209 is located between the saddle and the battery unit 207. Because the battery unit 207 is located within the scooter unit, more space is available for the installation of the helmet case 209.

[0106] The wheel unit 204 also includes a front wheel 2042. The distance between the axle of the front wheel 2042 and the axle of the rear wheel 2041 is defined as the wheelbase of the scooter 200, which is M1. The perpendicular distance from the centerline of the battery unit 207 in the longitudinal direction to the axle of the front wheel 2042 is M2, where M2 / M1 is greater than or equal to 0.3 and less than or equal to 0.8. The front side of the battery unit 207 is the side of the battery unit 207 closest to the front wheel 2042, and the rear side of the battery unit 207 is the side of the battery unit 207 closest to the rear wheel 2041. By rationally arranging the position of the battery unit 207, interference between the battery unit 207 and the front wheel 2042, suspension unit 205, and rear wheel 2041 can be avoided, making the scooter 200 more stable, safer, and more maneuverable during driving, and improving the overall operating efficiency of the vehicle.

[0107] The battery unit 207 is located between the first frame and the second frame, and is connected to both the first and second frames. By placing the battery unit 207 between the first and second frames, it can be considered part of the frame unit 201, saving the original frame and thus reducing the overall weight of the vehicle. At the same time, it simplifies the installation and arrangement of the battery unit 207, eliminating the limitations imposed by the position and structure of the frame unit 201. Furthermore, the battery unit 207 also provides support, bearing the indirect or direct mounting of components on the scooter 200.

[0108] The first frame, the second frame, and the battery unit 207 are connected by locking components. These locking components include bolts, but can also be other components with locking functions.

[0109] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
