[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0025] like Figure 1 As shown, this application provides an electric motorcycle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, and a power system 15.

[0026] The body panel 12 includes a seat assembly 121 and at least partially covers the frame 11. The running system 13 is at least partially disposed under the frame 11 and includes front wheels 131 and rear wheels 132. 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.

[0027] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The 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.

[0028] As one implementation method, such as Figure 2As shown, the frame 11 includes a front frame 111, a bottom frame 112, and a rear frame 113 connected in sequence. Viewed along the length of the electric motorcycle 100, the frame 11 is substantially symmetrical about its central axis.

[0029] 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.

[0030] 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°.

[0031] In this embodiment, the chassis 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 chassis 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 chassis 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Please see Figure 1 The walking system 13 includes two types of wheels: a front wheel 131 and a rear wheel 132. The following description uses the rear wheel 132 as an example to illustrate this technical solution, but it is not limited to the rear wheel 132. In some embodiments, the front wheel 131 is also applicable to this technical solution.

[0036] Please see Figure 3 and Figure 4 In some embodiments, the rear wheel 132 includes a rim 1321, a hub 1322, and spokes 1323. The hub 1322 is rotatably connected to the suspension system 14 via a rotating shaft. The hub 1322 has a central axis, and the rim 1321 is arranged around the hub 1322 about its central axis. The rim 1321 also has a central axis, which is coaxial with the central axis of the hub 1322. The spokes 1323 are disposed between the hub 1322 and the rim 1321, and are fixedly connected to the hub 1322 and the rim 1321.

[0037] Please see Figure 4 and Figure 5 In some embodiments, the rim 1321 forms a wheel cavity, which includes a connecting space 1321a and a motor space 1321b that are substantially symmetrical along the width direction of the frame 11. The power system 15 also includes a drive motor 153, which is electrically connected to the power battery 151. The drive motor 153 is at least partially located within the motor space 1321b, forming a side-mounted installation configuration.

[0038] In some embodiments, the connection space 1321a and the motor space 1321b are substantially the same size.

[0039] In some embodiments, a receiving groove 1321c is provided on the surface of the rim 1321 away from the hub 1322. The receiving groove 1321c is provided on the outer surface of the rim 1321 and recessed inward to form an annular groove surrounding the central axis of the rim 1321.

[0040] The rear wheel 132 also includes a valve stem 1324, and the electrical system 18 also includes a tire pressure sensor 184. The tire pressure sensor 184 is located in the receiving groove 1321c. The valve stem 1324 is connected to the tire pressure sensor 184 and extends through the inner wall of the receiving groove 1321c into the connecting space 1321a. The valve stem 1324 and the drive motor 153 are staggered and distributed in two different spaces, thereby improving the problem of positional interference between the side-mounted drive motor 153 and the valve stem 1324.

[0041] Please see Figure 5 and Figure 6 In some embodiments, the valve 1324 is inclined along the side away from the wheel motor space. The inclined valve 1324 can improve the problem of interference with the wheel spokes 1323 and improve the convenience of charging and decharging the valve 1324.

[0042] In some embodiments, the angle between the central axis of the valve stem 1324 and the central axis of the rim 1321 is between 30° and 60°, preferably between 35° and 50°.

[0043] Please see Figure 6 In some embodiments, the tire pressure sensor 184 includes a sensor body 1841 and a sensor housing 1842. The sensor body 1841 is housed within the sensor housing 1842. The sensor body 1841 is used to detect the air pressure in the rear wheel 132 and output a pressure value signal to the vehicle's mainboard.

[0044] The tire pressure sensor 184 also includes a sensor connector 1843, which passes through the sensor housing 1842 and is detachably connected to the valve stem 1324. By using the sensor connector 1843 to pass through the sensor housing 1842 and detachably connect to the valve stem 1324, the valve stem 1324 and the tire pressure sensor 184 can be pre-assembled, thereby reducing an assembly step when assembling the rear wheel 132 and improving assembly efficiency.

[0045] Please see Figure 6 In some embodiments, the sensor housing 1842 includes a main housing 1842a and an anti-rotation part 1842b. The sensor body 1841 is housed in the main housing 1842a, and the anti-rotation part 1842b is disposed on the side of the main housing 1842a. The anti-rotation part 1842b abuts against the receiving groove 1321c, thereby playing a role in restricting rotation during the assembly of the valve 1324.

[0046] Please see Figure 4 and Figure 6In some embodiments, the main housing 1842a is generally rectangular, with its length direction perpendicular to the extension direction of the central axis of the rim 1321, its width direction parallel to the extension direction of the central axis of the rim 1321, and its thickness direction facing the center of the rim 1321.

[0047] In some embodiments, the anti-rotation part 1842b is configured as an anti-rotation boss, which is located on the side of the main housing 1842a along its length. The receiving groove 1321c has a bottom wall and a side wall, with the bottom wall of the receiving groove 1321c surrounding the central axis of the rim 1321. The side wall of the receiving groove 1321c is located on the side of the bottom wall of the receiving groove 1321c and is angled to the central axis of the rim 1321, with the anti-rotation boss abutting against the bottom wall of the receiving groove 1321c.

[0048] In other embodiments, the anti-rotation part 1842b is configured as an anti-rotation boss, which is located on the side of the main housing 1842a in the width direction and abuts against the side wall of the receiving groove 1321c.

[0049] In some embodiments, two anti-rotation bosses are provided, and the two anti-rotation bosses are respectively provided on different sides of the main housing 1842a, thereby improving the positional stability of the sensor housing 1842.

[0050] In some embodiments, the sensor housing 1842 further includes a valve connector 1842c, which is located on the side of the main housing 1842a in the width direction, and the valve 1324 is detachably connected to the valve connector 1842c.

[0051] The sensor housing 1842 also includes a reinforcing rib 1842d, which connects the main housing 1842a and the valve connection 1842c, thereby improving the connection strength between the main housing 1842a and the valve connection 1842c and increasing the service life of the tire pressure sensor 184.

[0052] 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.
