[0088] The control device 600 is used to send an acceleration signal to the drive motor 520 after receiving the first speed signal I, so as to increase the rotation speed of the power wheel 510;

[0089] The control device 600 is used to send a deceleration signal to the driving motor 520 after receiving the first speed signal II, so as to reduce the rotation speed of the power wheel 510.

[0090] The electronic control device includes a second mode switching device 640, which is disposed on the first handle 120 or the second handle 220, and is electrically connected to the control device 600.

When the user operates the second mode switching device 640 to generate the second switching signal I, the device enters the second mode I; when the user operates the second mode switching device 640 to generate the second switching signal II, the device enters the second mode II.

[0092] Second mode I: after receiving the second switching signal I, the control device 600 is used to send a second control signal I to the drive motor 520, so that the drive motor 520 drives the power wheel 510 to rotate at a constant speed, thereby achieving constant speed cruising in the assist state.

[0093] Second mode II: after receiving the second switching signal II, the control device 600 is used to send a second control signal II to the drive motor 520, so that the drive motor 520 generates a torque to drive the power wheel 510 to rotate, or generates a torque to hinder the rotation of the power wheel 510. In the second mode II, the device can automatically adjust the torque generated by the drive motor 520 according to the current motion state of the device, thereby achieving the purpose of assisting walking or exercising.

[0094] The seat portion 300 is provided with a third mode switching device 650, and the third mode switching device 650 is electrically connected to the control device 600. The third mode switching device 650 is used to generate a third switching signal. The user can switch the device to the third mode by operating the third mode switching device 650. When the user operates the third mode switching device 650 to generate the third switching signal, the device enters the third mode.

[0095] The third mode: after receiving the third switching signal, the control device 600 is used to send a third control signal to the drive motor 520, so that the drive motor 520 generates a torque that hinders the rotation of the power wheel 510. For example, when the user needs to train the strength of the limbs, the third mode switching device 650 can be operated.

[0099] The second speed regulating module I 671 and the second speed regulating module II 672 are used to generate a second speed signal I and a second speed signal II, respectively.

[0100] The control device 600 is used to send an acceleration signal to the drive motor 520 after receiving the second speed signal I, so as to increase the rotation speed of the power wheel 510;

[0101] The control device 600 is used to send a deceleration signal to the driving motor 520 after receiving the second speed signal II, so as to reduce the rotation speed of the power wheel 510.

[0103] The first detection device 681 is used to generate a first holding signal when the first grip 120 is held by the palm, and the second detection device 682 is used to generate a second holding signal when the second grip 220 is held by the palm. The control device 600 is used to send an unlocking signal to the drive motor 520 when receiving the first holding signal and the second holding signal at the same time, so that the drive motor 520 operates.

[0104] In the walking-assisting state, the drive motor 520 will be unlocked only when the user's hands simultaneously and respectively hold the first grip 120 and the second grip 220. In one embodiment, the first grip 120 corresponds to the right hand, and the second grip 220 corresponds to the left hand. At the same time, the right hand holds the first grip 120 and the left hand holds the second grip 220. At this time, the drive motor 520 will be unlocked, and accordingly, the drive motor 520 will be powered and run.

[0105] If only one hand holds the corresponding handle or both hands do not hold the corresponding handle, the drive motor 520 will not start, thereby ensuring the safety of the user, because only when both hands are supported can the user better maintain the balance of the body.
