[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Reference Figures 1 to 4 The present invention discloses a multifunctional disabled person's power-assisted walking rehabilitation device, comprising:

[0050] Base 1;

[0051] A driving mechanism is arranged at the bottom of the base 1, and is used to move and turn the base 1;

[0052] A power supply control module is arranged on the base 1, the power supply control module is electrically connected to the driving mechanism, and the power supply control module is used to control the driving mechanism;

[0053] A seat 2 is arranged on the base 1;

[0054] The pedal driving device 7 is arranged on one side of the seat 2. The output end of the pedal driving device 7 is drivingly connected to two exercise pedals 8. The input end of the pedal driving device 7 is arranged in contact with the ground. When the base 1 moves, the pedal driving device 7 drives the exercise pedals 8 to rotate.

[0055] When in use, the disabled person sits on the seat 2 and controls the driving mechanism through the power supply control module to drive the base 1 to move and turn. At the same time, the disabled person's lower limbs and feet are placed on the corresponding exercise pedals 8 respectively. During the movement of the base 1, since the input end of the pedal driving device 7 is in contact with the ground, the pedal driving device 7 can drive the two exercise pedals 8 to rotate during movement. At this time, the two exercise pedals 8 respectively drive the corresponding foot movements, and then drive the lower limbs to achieve bicycle-style rehabilitation exercises. While meeting the travel and mobility functions, the lower limb muscles can be exercised to ensure muscle activity.

[0056] As an optional embodiment, the pedal driving device 7 includes:

[0057] The magnetic blocking box 701 is arranged through the middle of the base 1, and the magnetic blocking box 701 is fixedly connected to the base 1;

[0058] The pedal driving wheel 705 is rotatably arranged on the top of the magnetic blocking box 701, and the front and rear sides of the rotating shaft of the pedal driving wheel 705 penetrate the side wall of the magnetic blocking box 701 and are respectively fixed to one end of the corresponding exercise pedal 8;

[0059] The driven wheel 702 is rotatably disposed at the bottom of the magnetic blocking box 701 , the bottom of the driven wheel 702 is in contact with the ground, and the driven wheel 702 is transmission-connected to the pedal driving wheel 705 .

[0060] The driven wheel 702 is in contact with the ground and can rotate when the base 1 moves. The driven wheel 702 is connected to the pedal driving wheel 705. When the driven wheel 702 rotates, the pedal driving wheel 705 rotates at the same time to drive the two exercise pedals 8 to move, thereby realizing the function of lower limb rehabilitation.

[0061] As an optional implementation, a plurality of permanent magnets 706 are fixedly connected to the edge of the pedal driving wheel 705 at equal intervals in the circumferential direction, and the polarities of two adjacent permanent magnets 706 are opposite;

[0062] A plurality of electromagnetic groups are fixedly connected to the edge of the driven wheel 702 at equal intervals in the circumferential direction. The electromagnetic groups are magnetically connected to the corresponding permanent magnets 706, and the polarities of two adjacent electromagnetic groups are opposite.

[0063] A plurality of electromagnetic groups are electrically connected to the power supply control module.

[0064] As an optional implementation, the electromagnetic group includes a plurality of electromagnetic coils 703 arranged at intervals, and the electromagnetic coils 703 are electrically connected to the power supply control module.

[0065] As an optional implementation, both ends of the electromagnetic coil 703 are electrically connected to conductive contact posts 704, which are respectively located at the front and rear sides of the driven wheel 702, and the conductive contact posts 704 are slidably contacted with an annular guide slideway 707, which is provided on the front and rear side walls of the magnetic resistance box 701;

When the driven wheel 702 rotates, the conductive contact posts 704 at both ends of the electromagnetic coil 703 move along the annular guide slide 707. When the conductive contact posts 704 at both ends of one electromagnetic coil 703 contact the corresponding conductive metal sheet 708, the circuit is connected, and magnetism is generated by energizing the electromagnetic coil 703. At this time, the corresponding permanent magnet 706 on the pedal drive wheel 705 is magnetically connected to the energized electromagnetic coil 703, and the electromagnetic coil 703 moves as the driven wheel 702 rotates. Since the two adjacent electromagnetic coils 703 are arranged at intervals, The magnetic field will move with the movement of the electromagnetic coil 703, so that it can drive the pedal drive wheel 705 to rotate when it moves. By controlling the positive and negative poles of the two conductive metal sheets 708, the polarity of the electromagnetic coil 703 electrically connected to the two conductive metal sheets 708 can be controlled. When the polarity between the two conductive metal sheets 708 does not change, any number of electromagnetic coils 703 passing through the two conductive metal sheets 708 constitute a first electromagnetic group. After the polarity of the two conductive metal sheets 708 changes, any number of electromagnetic coils 703 passing through the two conductive metal sheets 708 constitute a second electromagnetic group. The polarities of the two electromagnetic groups are opposite. The rotation speed of the pedal drive wheel 705 can be controlled by controlling the speed of the polarity change of the electromagnetic group and coordinating the current size to control the magnetic force.
