The steering assembly includes a steering rod, a steering handle mounted at the upper end of the steering rod, and a steering wheel mounted at the lower end of the steering rod. The pedal assembly includes a pedal frame for a user to step on, and a riser tube located at the front end of the pedal frame and sleeved with the steering rod. The riser tube is located between the steering handle and the steering wheel. The drive control system includes a controller and a power source mounted on the pedal frame, a control throttle mounted on the steering handle and connected to the controller, and a power wheel mounted at the rear end of the pedal frame and controlled by the controller. The control throttle is connected to the controller through a signal wire to feedback the user's control instructions to the controller.

[0003] Currently, the signal wire is mainly connected to the control throttle and the controller through the following three setting methods. First: The signal wire is completely exposed outside the vehicle frame. Second: A part of the wire body of the signal wire is arranged inside the steering rod between the steering handle and the riser tube. A wire hole for the signal wire to penetrate is provided on the steering rod between the steering handle and the riser tube. The other part of the wire body of the signal wire penetrates through the wire hole and extends outside the vehicle frame, and the other part of the wire body extending outside the vehicle frame is then connected to the controller. Third: A wire groove is provided on the outer wall of the steering rod between the steering handle and the riser tube. A part of the wire body of the signal wire penetrates through the wire groove, and the other part of the wire body of the signal wire extends outside the wire groove and is exposed outside the vehicle frame, and the other part of the wire body extending outside the wire groove is then connected to the controller.

[0004] The signal wires in the above three setting methods are completely or partially exposed outside the vehicle frame, which easily causes the signal wires to collide and entangle with objects other than the electric scooter, resulting in the signal wires being torn off, and there are safety hazards; the signal wires are exposed outside the vehicle frame for a long time, which will also exacerbate the aging degree and reduce the aesthetics of the vehicle.

[0027] Referring to Figure 1 and Figure 2 , this embodiment provides an electric scooter, which includes a pedal assembly 1, a front wheel 11 and a rear wheel 12 mounted on the pedal assembly 1, a steering device 2 mounted on the front part of the pedal assembly 1 for controlling the steering of the front wheel 11, a controller 13 for controlling the operation of the electric scooter, and a power source 14. A control device 221 connected to the controller 13 is provided on the steering device 2. The rear wheel 12 is a hub motor wheel. The power source 14 is electrically connected to the controller 13, the hub motor wheel and other electronic devices on the electric scooter to provide working power. The controller 13 controls the rotation of the hub motor wheel, and the front wheel 11 is driven by the hub motor wheel. When a user rides on the electric scooter, the control device 221 feeds back the user's control instructions to the controller 13. The controller 13 calculates and processes the control instructions and then controls the operation of the electric scooter, and controls the traveling direction of the electric scooter through the steering device 2.

[0028] In this embodiment, the pedal assembly 1 includes a riser 15, a pedal frame 16 on which the controller 13 is installed, and a connecting pipe 17 with both ends respectively connected to the riser 15 and the pedal frame 16. The two feet of the user can step on the upper part of the pedal frame 16 at the same time. The front wheel 11 is installed on the riser 15 through a fork 18. The rear wheel 12 is installed on the pedal frame 16 through an axle, and a shock absorber is provided between the axle and the pedal frame 16. A wheel cover is provided above the rear wheel 12. A footrest 18 is provided on the pedal frame 16. The riser 15 is inclined obliquely upward and backward of the electric scooter, so that the top end (steering handle 22) of the steering device 2 is offset backward to provide a better riding posture for the user. The connecting pipe 17 is inclined obliquely upward and forward of the electric scooter to coordinate the installation positions of the pedal frame 16, the front wheel 11, the riser 15 and the steering device 2, making the structure of the electric scooter more compact.

[0029] Referring to Figure 2 and Figure 3, the steering device 2 includes a steering tube 21 sleeved on the riser 15 and a steering handle 22 fixedly connected to the steering tube 21. The steering tube 21 is connected to the fork 18 and controls the rotation of the fork 18. When the user rotates the steering handle 22, the fork 18 can be driven to rotate relative to the riser 15 through the steering tube 21 to control the front wheel 11 to turn left or right. The control device 221 is installed on the steering handle 22 for the convenience of the user to operate. The control device 221 is connected to the controller 13 through a signal line 23. A first wire hole 24 through which the signal line 23 passes is formed in the steering tube 21. The signal line 23 is installed in the hollow space of the steering device 2 and the pedal assembly 1. Among them: the signal line 23 installed on the steering device 2 is placed in the tubular space of the steering tube 21, one end is connected to the control device 221, and the other end extends out from the first wire hole 24 and extends in the direction of the controller 13 installed on the pedal bracket 16.

[0030] The pedal bracket 16 has an accommodation space 19. The controller 13 and the power supply 14 are both installed in the accommodation space 19. One end of the connecting pipe 17 extends into the accommodation space 17, so that the tubular space of the connecting pipe 17 communicates with the accommodation space 19 of the pedal bracket 16; the other end of the connecting pipe 17 intersects with the riser 15, and a second wire hole 170 through which the signal line 23 passes is formed in the riser 15, so that the tubular space of the riser 15 communicates with the tubular space of the connecting pipe 17. Among them: the signal line 23 installed on the pedal assembly 1 is led out from the first wire hole 24, passes through the second wire hole 170 and the connecting pipe 17, and then is connected to the controller 13. The setting method of the signal line 23 of the present invention forms a through structure in which the tubular space of the steering tube 21, the tubular space of the riser 15, the tubular space of the connecting pipe 17 and the accommodation space of the pedal bracket 16 communicate with each other by providing the first wire hole 24 on the steering tube 21 and the second wire hole 170 on the riser 15. The signal line 23 is arranged in this through structure, which can avoid the signal line 23 from contacting the outside of the vehicle frame and can be better hidden in the vehicle body, not only improving the driving safety but also improving the aesthetics of the vehicle.

[0031] It should be noted that: in other embodiments, the controller 13 and the power supply 14 can also be installed in the tubular space of the connecting pipe 17, and the height of the controller 13 and the power supply 14 relative to the ground can be raised through the connecting pipe 17 inclined forward and upward to improve the waterproof performance of the controller 13 and the power supply 14.

[0032] Refer to Figure 3 and Figure 4, in this embodiment, the steering tube 21 includes a first tube body 25 sleeved on the riser 15 and a second tube body 26 fixedly connected to the first tube body 25. The fork 18 for mounting the front wheel 11 is connected to the first tube body 25 and rotates with the first tube body 25. The steering handle 22 is fixedly connected to the second tube body 26. The first tube body 25 penetrates through the riser 15 and can rotate relative to the riser 15. There is an upper cup 27 between the top end of the first tube body 25 and the riser 15, and a lower cup 28 between the lower end of the first tube body 25 and the riser 15. A gasket 34 is provided between the upper cup 27 and the riser 15. The first tube body 25 is rotatably connected to the riser 15 through the upper cup 27 and the lower cup 28. An external thread 251 is provided on the outer periphery of the top end of the first tube body 25, and a lock nut 29 is fitted and installed. The top end of the first tube body 25 extends into the second tube body 26 and is fixedly connected through a fastener.

[0033] The top end of the fork 18 extends into the first tube body 25. A partition 252 for connecting the fork 18 is provided in the tubular space of the first tube body 25. An internal thread hole 181 is provided along the axis of the first tube body 25 at the top end of the fork 18, and a through hole 253 for fitting the screw 29 is provided on the partition 252. The nut of the screw 29 is located above the partition 252, and the screw part of the screw 29 passes through the through hole 253 and is threadedly connected to the internal thread hole 181 to install the fork 18 and prevent the fork 18 from detaching from the first tube body 25. A first shock-absorbing spring 30 is provided between the upper end of the fork 18 and the partition 252. The top end of the fork 18 is connected to the first tube body 25 through a radial limiting sleeve 31. The radial limiting sleeve 31 is sleeved on the outer periphery of the top end of the fork 18. The socket hole of the radial limiting sleeve 31 is a square through hole. The cross-section of the top end of the fork 18 is square and matches the square through hole. The radial limiting sleeve 31 is fixedly connected to the first tube body 25 through a fixing sleeve 32. A second shock-absorbing spring 33 is provided between the shoulder of the fork 18 and the fixing sleeve 32. The fork 18 is connected to the first tube body 25 through the second shock-absorbing spring 33, the radial limiting sleeve 31, the first shock-absorbing spring 30 and the screw 29, so that the fork 18 can only move along the axial direction of the first tube body 25 relative to the first tube body 25, cannot rotate in the radial direction, and rotates relative to the riser 15 following the first tube body 25.

[0034] Refer to Figure 4 and Figure 5, in this embodiment, the first pipe body 25 includes an opening section, and the position of the opening section corresponds to the intersection part of the riser pipe 15 and the connecting pipe 17. The first wire hole 24 is located on the opening section, so that the opening position of the first wire hole 24 corresponds to the opening position of the second wire hole 170, in order to reasonably arrange the routing structure of the signal wire 23. A strengthening part is provided on the opening section. Through the strengthening part, the local structural damage caused by the opening of the first wire hole 24 in the first pipe body 25 can be compensated, thereby increasing the structural strength and torsional resistance of the first pipe body 25, and avoiding the phenomenon that the first pipe body 25 is torsionally broken. The strengthening part is a reinforcing rib 254 protruding from the wall body of the first pipe body 25. The reinforcing rib 254 is arranged on the outer wall or the inner wall of the first pipe body 25. The number of the reinforcing ribs 254 is set according to the design requirements, and more than one reinforcing rib 254 is circumferentially distributed on the first pipe body 25. Of course, in other embodiments, the strengthening part can also be a reinforcing ring welded to the first pipe body 25.

[0035] In this embodiment, the strengthening part is a reinforcing rib 254. The reinforcing rib 254 is arranged from top to bottom along the wall body of the first pipe body 25, and its shape is linear, curved or spiral. The length of the reinforcing rib 254 is not less than the length of the opening section, which can further improve the structural strength and torsional resistance of the first pipe body 25.

[0036] In this embodiment, the number of the reinforcing ribs 254 is two. The two reinforcing ribs 254 are arranged at intervals on the outer wall of the opening section. The two reinforcing ribs 254 are respectively located on both sides of the first wire hole 24. A limiting rib 151 is provided on the inner wall of the riser pipe 15 sleeved on the outer periphery of the first pipe body 25. The limiting rib 151 is located between the two reinforcing ribs 254. When the user rotates the steering handle 22, the first pipe body 25 is driven to rotate relative to the riser pipe 15. The limiting rib 151 combined with the two reinforcing ribs 254 can limit the rotation angle of the steering handle 22 to the left or right, and prevent the electric scooter from tipping over when the steering angle is too large. The two reinforcing ribs 254 and the limiting rib 151 are both linear and parallel to the axis line of the first pipe body 25, which can further improve the cooperation degree between the limiting rib 151 and the two reinforcing ribs 254 to control the rotation angle of the steering handle 22.

[0037] In this embodiment, the first wire hole 24 is a rectangular hole. The rectangular hole has a set of two opposite opening edges along the length direction of the first pipe body 25. The two reinforcing ribs 254 are linear and are respectively arranged along the two opening edges to increase the opening structural strength of the first wire hole 24 and prevent the wall body of the first pipe body 25 from being sprained at the opening. The corners of the rectangular hole are provided with rounded corners, which can further increase the opening structural strength of the first wire hole 24. Of course, in other embodiments, the first wire hole 24 can also be an oval hole, and the two reinforcing ribs 254 are correspondingly curved to match the opening edge of the oval hole, which also increases the opening structural strength of the first wire hole 24.

[0038] In this embodiment, the first wire hole 24 and the second wire hole 170 are oppositely arranged, so that the opening of the first wire hole 24 corresponds to the opening of the second wire hole 170, which further facilitates the routing of the signal wire 23. The size of the overlapping part between the first wire hole 24 and the second wire hole 170 is greater than or equal to the cross-sectional size of the signal wire 23. When the user rotates the steering handle 22, the first wire hole 24 rotates relative to the vertical pipe 15 following the first pipe body 25, and the overlapping part between the first wire hole 24 and the second wire hole 170 gradually decreases. When the limiting rib 151 abuts against any one of the two reinforcing ribs 254, the rotation angle of the first pipe body 25 can be limited, and at the same time, it can be ensured that there is always a gap space for the signal wire 23 to pass through between the first wire hole 24 and the second wire hole 170, preventing the signal wire 23 from being squeezed and broken.

[0039] It should be noted that: when the lighting lamp installed on the steering handle 22 is connected to the power supply 14 through the power cord, there is always a gap space for the power cord to pass through between the first wire hole 24 and the second wire hole 170; when the brake handle installed on the steering handle 22 is connected to the brake disc installed on the rear wheel 12 through the brake wire, there is always a gap space for the brake wire to pass through between the first wire hole 24 and the second wire hole 170. This limiting structure enables the signal wire 23, the power cord and the brake wire to be hidden in the vehicle body.

[0040] Refer to Figure 5 , in this embodiment, the vertical pipe 15 includes a first inner lining pipe 152 sleeved on the outer periphery of the opening section, a first outer fixing pipe 153 located outside the first inner lining pipe 152, and a plurality of first rib strips 154 respectively connecting the first inner lining pipe 152 and the first outer fixing pipe 153 at both ends. The number of the first rib strips 154 is three to six. The plurality of first rib strips 154 are arranged circumferentially and extend along the length direction of the vertical pipe 15. This vertical pipe structure has good structural strength. The first pipe body 25 of the steering pipe 21 is rotatably connected to the first inner lining pipe 152. The second wire hole 170 penetrates through the first inner lining pipe 152 and the first outer fixing pipe 153, so that the tubular space of the first inner lining pipe 152 and the tubular space of the connecting pipe 17 form a through structure to facilitate wire laying.

[0041] Refer to Figure 6 and Figure 7, in this embodiment, the second pipe body 26 of the steering pipe 21 includes a second inner lining pipe 261 sleeved on the first pipe body 25, a second outer fixing pipe 262 located on the periphery of the second inner lining pipe 261, and a plurality of second rib strips 263 respectively connecting the two ends of the second inner lining pipe 261 and the second outer fixing pipe 262. The number of the second rib strips 263 is three to six. The plurality of second rib strips 263 are arranged circumferentially and extend along the length direction of the second pipe body 26. The structure of the second pipe body 26 further improves the structural strength of the steering rod. A clamping groove 264 is formed in the pipe wall at one end of the second pipe body 26 sleeved on the first pipe body 25 along the axial direction of the steering pipe 21. One end pipe wall of the above-mentioned first pipe body 25 is composed of the second inner lining pipe 261 and the second outer fixing pipe 262. Two of the plurality of second rib strips 263 are respectively located on both sides of the clamping groove 264, and the two second rib strips 263 are locked and fixed by fasteners. The fasteners lock the two second rib strips 263 to reduce the gap of the clamping groove 264, so that the second pipe body 26 and the first pipe body 25 are fixedly connected.

[0042] The above two second rib strips 263 are the first clamping rib plate 265 and the second clamping rib plate 266 arranged oppositely. The first clamping rib plate 265 is correspondingly provided with a first clamping block 267, and the second clamping rib plate 266 is correspondingly provided with a second clamping block 268. Both the first clamping block 267 and the second clamping block 268 are located between the second inner lining pipe 261 and the second outer fixing pipe 262. The fastener is a bolt 269. The first clamping block 267 is recessed with a receiving space for receiving the head of the bolt 269, the second clamping block 268 is provided with a threaded hole threadedly connected with the rod portion of the bolt 269, and both the first clamping rib plate 265 and the second clamping rib plate 266 are provided with first bolt through holes through which the rod portion of the bolt passes, and the pipe wall of the second outer fixing pipe 262 is provided with second bolt through holes through which the head of the bolt passes. The first clamping block 267 and the second clamping block 268 are connected by bolts to lock the two second rib strips 263. Of course, in other embodiments, the fastener can also be a locking buckle or a clamp.

[0043] It should be noted that: in this embodiment, the number of the bolts 269 is three to further lock the two second rib strips 263. The arrangement directions of two of the bolts are opposite to those of the other bolt, and the other bolt is located between the two bolts.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced; and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention.
