Safety and convenience: when the (4) person 2 (9) depends, the carrier 42 can be mounted on the carrier 42 and the corresponding driven wheel 34 is clamped with the brake 41 to prevent the base 32 from being The driven wheel generates a sliding for the user 2GG to directly ride back to restore physical strength, and there is no need to see another rest; in addition, when the 纟 2GG is used, the carrier 42 can select the user 200 and effectively prevent the use. The squatter 2 sits down on the ground, so the walker 2 is safer and more convenient to use. Referring to FIG. 5, the second embodiment of the present invention is substantially the same as the first preferred embodiment, and includes a mobile unit 3 and a control unit 4 disposed on the mobile unit 3, wherein The same is the same as that: the assisting device 2 further includes a steering unit 5, the steering unit 5 includes a steering rod 51 pivotally disposed on the lower frame 321, the upper frame 322 and the support plate 324. The steering rod 51 faces one end of the ground and touches the driving wheel 52 ′ on the ground and a grip 设置 disposed on the other end of the steering rod 51 opposite to the driving wheel 52 7 201043217 and located above the supporting plate 324 . Since the overall structure of the present embodiment is substantially the same as that of the above-described first preferred embodiment, the various functions mentioned above can be achieved by the present embodiment, and the details are not described herein again. The maneuverability of the walker 2 of the present invention can be improved by rotating "pushing 53 to drive the drive wheel 52 to change direction, thereby changing the direction of movement of the base 32 as indicated by arrow 63 in FIG. Referring to Figures 6, 7', a third preferred embodiment of the walker 2 of the present invention is substantially the same as the second preferred embodiment, comprising a mobile unit 3, a control unit placed on the mobile unit 3. 4, and - steering unit $, in the basin, the same: the steering unit 5 further includes a power source 54 capable of driving the active 52, and a brake member 55 for clamping the driving wheel And the control unit 4 further includes: a controller 43 disposed on the gripper to electrically connect the power source and the brake member 55, and an electric connection = a brake member 55, a brake device 34, and a power source 54 „ 4 4, where f zhai 43 controls the power source 54 to change between a training mode and an operating mode. In the preferred embodiment, the power source 54 is a motor and the brake member 55 is an electromagnetic brake. Referring to FIGS. 6, 7, and 8, when in the operation mode, the power source 54 drives the tilting wheel 52 to rotate to drive the base 32 to move. At this time, the brake device 34 and the brake member 55 and the power source and the 54 are both The switch 44 is opened and closed for the switch 44. Therefore, when in the operation mode, the user's specification can be carried on the carrier 42 and then moved with the base 32' and by manipulating the steering unit $201043217 Ο 、 53 m changes the moving direction of the base 32. Therefore, when the user is too tired, the user can switch to the operation mode, and the movement of the power source 54 drives the user 200 to move, so as to avoid being too tired and unable to return to the original 2 In the case of the stop, when the stop switch is required, the power source 54 can be stopped at the same time, and the driven wheel 33 is clamped by the sensor, the cymbal and the brake member 55, respectively. Referring to Figure 9 and referring back to Figures 6 and 8, when in the training mode, the source 54 is not actuated and the brake 34 and the brake member 55 are opened and closed for the sense, that is, It is said that the pedestal 32 is still required to be pushed by the squatter to achieve the auxiliary device 2 The effect of the user 200 moving, of course, if the user feels the fatigue and punishment, the user can still ride on the provincial carrier 42 and cooperate with the sensor 41 and the brake device w and the brake: 55 system. The driven wheel 33 and the driving wheel 52 can still prevent: the base 32 is slid by the driven wheel 33 or the driving wheel 52, so that the user 200 can directly ride to restore physical strength, and no need to see another resting place. When the person 200 is inadvertently soft, the carrier 42 can still support the user 2 to effectively prevent the user 2 from falling down on the ground. It should be particularly noted here that how the controller 43 is switched between the training mode and the operation mode is a conventional technique in the field of program control, and therefore will not be described here. In summary, the walker 2 of the present invention is a rolling of the driven rim relative to the ground, which reduces the force required by the user 2GG to push the base 32 to cooperate with the movable space 31 and the sensor 41. Limiting the movement range of the user 2〇0, the other side can clamp the corresponding driven wheel 33, 9 201043217 to avoid the base 32 from dumping or slipping, and the carrier 42 can not only carry the user 200 to avoid The user 200 accidentally falls down on the ground, and can also rest for the tired user 200 to rest and restore physical strength. Therefore, the helper 2 of the present invention is more labor-saving, safe and comfortable to use, and thus the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are all It is still within the scope of the invention patent.
