A suspension system 14 connects the front wheels 131 and rear wheels 132 to the frame 11. A power system 15 is supported by the frame 11 and drives the running system 13.

[0025] Furthermore, the wheelbase of the electric motorcycle 100 in this embodiment ranges from 1260 mm to 1320 mm, preferably 1300 mm. The electric motorcycle 100 in this embodiment has a short wheelbase, resulting in a compact overall structure and flexible operation. It should be noted that, unless otherwise defined, the "wheelbase" in this embodiment refers to the straight-line distance between the front and rear axles of a vehicle as defined in vehicle engineering. Specifically, the "front axle" of the electric motorcycle 100 typically refers to the centerline or bearing location of the front wheel 131, while the "rear axle" refers to the centerline or bearing location of the rear wheel 132.

[0026] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1The front, rear, left, right, top, and bottom sides are shown. In this embodiment, the front, rear, left, right, top, and bottom directions refer to the directions when the electric motorcycle 100 is on a horizontal plane. The front-rear direction refers to the length direction of the electric motorcycle 100 provided in this application, the left-right direction refers to the width direction of the electric motorcycle 100 provided in this application, and the up-down direction refers to the height direction of the electric motorcycle 100 provided in this application.

[0027] As one implementation method, such as Figure 2 As shown, the frame 11 includes a front frame 111, a middle frame 112, and a rear frame 113 connected in sequence. Viewed along the length of the electric motorcycle 100, the frame 11 is basically symmetrical about its central axis.

[0028] In this embodiment, the front frame 111 includes a head tube 1111 and a main tube 1112. The main tube 1112 is connected to the middle of the head tube 1111, and the main tube 1112 is substantially perpendicular to the horizontal plane. There is an angle between the axis of the head tube 1111 and the axis of the main tube 1112. The front wheel 131 is connected to the head tube 1111 through a suspension system 14. Specifically, the suspension system 14 includes a front fork 141, and the front wheel 131 is connected to the head tube 1111 through the front fork 141.

[0029] It should be noted that the descriptions of "horizontal" and "vertical" in this embodiment are not strictly "horizontal" or "vertical" in the mathematical sense. They may have a certain angular error, for example, 5°~10°.

[0030] In this embodiment, the mid-frame 112 includes a main support 1121, a secondary support 1122, and a bottom support 1123. The main support 1121 is connected to both sides of the lower part of the front frame 111. For example, the main support 1121 includes two main supports, left and right, with one end of each main support 1121 connected to the left and right sides of the lower part of the front frame 111, respectively. Specifically, the main supports 1121 on both sides include a first pipe segment 1121a, a second pipe segment 1121b, and a third pipe segment 1121c connected in sequence. One end of the first pipe segment 1121a is connected to the lower side of the main pipe 1112, and the other end of the first pipe segment 1121a extends substantially to the side of the electric motorcycle 100. One end of the second pipe segment 1121b is connected to the other end of the first pipe segment 1121a, and the other end of the second pipe segment 1121b extends substantially downwards from the electric motorcycle 100. One end of the third pipe segment 1121c is connected to the other end of the second pipe segment 1121b, and the other end of the third pipe segment 1121c extends substantially towards the rear of the electric motorcycle 100. The pipe segments are smoothly connected by curved bends.

[0031] One end of the sub-support 1122 is connected to the second pipe segment 1121b, and the other end of the sub-support 1122 is connected to the rear frame 113. For example, the connection point between the sub-support 1122 and the second pipe segment 1121b is located in the middle of the second pipe segment 1121b, and the connection point between the sub-support 1122 and the rear frame 113 is located at the lower part of the rear frame 113. The sub-support 1122 and the third pipe segment 1121c are arranged substantially parallel to each other.

[0032] The middle part of the bottom bracket 1123 is connected to the bottom of the front frame 111, and the two ends of the bottom bracket 1123 are respectively connected to the second pipe segment 1121b of the main bracket 1121 on the left and right sides. For example, the middle part of the bottom bracket 1123 is connected to the bottom of the main pipe 1112. The connection point between the bottom bracket 1123 and the second pipe segment 1121b and the connection point between the auxiliary bracket 1122 and the second pipe segment 1121b can be the same, or one connection point can be higher than the other connection point. This embodiment does not limit this.

[0033] In this embodiment, the bottom bracket 1123 is provided, which can effectively improve the rigidity of the frame 11 and enhance the stability of the vehicle handling.

[0034] Please see Figure 2 and Figure 3 In some embodiments, the electric motorcycle 100 also includes an electrical system 18 supported by a mid-frame 112. The electrical system 18 includes a junction box assembly 183, which is located above the power battery 151 along the height direction of the frame 11.

[0035] The rear frame 113 includes a seat bucket support frame 1131, which is fixedly connected to the sub-support 1122. The seat bucket support frame 1131 includes a wiring cross tube 1131a that is generally arranged along the width direction of the frame 11, and the wiring cross tube 1131a is located above the power battery 151.

[0036] In some embodiments, the junction box assembly 183 includes a wiring connection plate 1831, a junction box body 1832, a wiring support plate 1833, and a wiring connection post 1834. The wiring connection plate 1831 is fixedly connected to the wiring horizontal tube 1131a. Along the height direction of the frame 11, the wiring support plate 1833 is located below the wiring connection plate 1831. An installation space 1835 is formed between the wiring support plate 1833 and the wiring connection plate 1831. The wiring connection post 1834 is fixedly connected to the wiring support plate 1833 and the wiring connection plate 1831. The junction box body 1832 is located within the installation space 1835.

[0037] In some embodiments, the junction box body 1832 is fixedly connected to the junction box plate 1833.

[0038] In some embodiments, the wiring tray 1833 is located below the wiring connection plate 1831, the wiring connection post 1834 is fixedly connected to the wiring tray 1833 and the wiring connection plate 1831 and together form the installation space 1835, the junction box body 1832 is located in the installation space 1835 and is fixedly connected to the wiring tray 1833, and the wiring connection plate 1831 is fixedly connected to the wiring horizontal tube 1131a and located above the power battery 151, thereby improving the problem of the junction box assembly 183 occupying the installation space 1835 of the power battery 151 and improving the space utilization rate of the power battery 151.

[0039] Please see Figure 3 In some embodiments, the junction box body 1832 has an inlet connection port 1832a and an outlet connection port 1832b, which are arranged substantially along the width direction of the frame 11, thereby facilitating the connection of the wiring harness with the junction box body 1832.

[0040] In some embodiments, two wiring connection posts 1834 are provided, and the two wiring connection posts 1834 are basically spaced apart along the width direction of the frame 11. The installation space 1835 is located between the two wiring connection posts 1834. The two wiring connection posts 1834 limit the position of the junction box body 1832 along the width direction of the frame 11, thereby improving the positional stability of the junction box body 1832.

[0041] In some embodiments, the outer peripheral surface of the wiring connection post 1834 is cylindrical. The cylindrical wiring connection post 1834 can effectively improve the problem of wire harness damage caused by friction between the wire harness and the wiring connection post 1834.

[0042] Please see Figure 3 and Figure 4 In some embodiments, the junction box assembly 183 further includes a clamping member 1836, which is fixed below the junction box 1833 and is used to clamp the power battery 151.

[0043] In some embodiments, the clamping member 1836 includes a roller bracket 1836a and a clamping roller 1836b. The roller bracket 1836a is fixed below the terminal block 1833, and the clamping roller 1836b is rotatably connected to the roller bracket 1836a and has a rotation axis. The rotation axis of the clamping roller 1836b is arranged substantially along the width direction of the vehicle frame 11, and the clamping roller 1836b clamps the power battery 151.

[0044] The rotation axis of the clamping roller 1836b is set basically along the width direction of the frame 11, so that when the power battery 151 is picked up or put down, the rolling direction of the clamping roller 1836b is the same as the picking and putting-down direction of the power battery 151, thereby improving the convenience of replacing the power battery 151.

[0045] In some embodiments, along the height direction of the frame 11, the orthographic projection of the roller bracket 1836a on the horizontal plane at least partially overlaps with the orthographic projection of the wiring connection post 1834 on the horizontal plane. Since the bending strength of the wiring tray 1833 is limited, by placing the roller bracket 1836a below the wiring connection post 1834, the installation stability of the roller bracket 1836a is improved via the wiring connection post 1834.

[0046] In some embodiments, the surface of the pressure roller 1836b is elastic, and the elastically configured pressure roller 1836b can make elastic contact with the surface of the power battery 151, thereby improving the problem of the pressure roller 1836b damaging the surface of the power battery 151.

[0047] In some embodiments, the wiring tray 1833 includes a first support portion 1833a, a clearance portion 1833b, and a second support portion 1833c. The clearance portion 1833b is located between the first support portion 1833a and the second support portion 1833c, and is recessed to form a rectangular clearance area. Along the height direction of the frame 11, the height of the clearance portion 1833b is lower than the height of the first support portion 1833a and the second support portion 1833c. The junction box body 1832 is fixedly connected to the first support portion 1833a and the second support portion 1833c. A gap is formed between the clearance portion 1833b and the junction box body 1832 to facilitate heat dissipation from the junction box body 1832.

[0048] In some embodiments, the clearance portion 1533b is provided with a plurality of counterweight holes. Further, the cross-section of the counterweight holes can be circular or rectangular. In this embodiment, the specific shape and location of the counterweight holes are not limited, as long as the load-bearing strength of the wiring tray 1533 on the junction box body 1832 is guaranteed. Providing counterweight holes can reduce the weight of the wiring tray 1833 while ensuring strength, and can also improve the heat dissipation effect on the junction box body 1832.

[0049] In some embodiments, the first support portion 1833a, the clearance portion 1833b, and the second support portion 1833c are integrally formed from sheet metal material.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
