Regarding the use of the present invention, the following description is given: the driving thigh bracket 2 is lifted relative to the calf support 1, and the user manipulates the clutch lever 34 to push the runner 342 of the shaft section 341 against the driven member 33 (Fig. 6 to 7). As shown in the figure, and during the process, the sliding section 343 is moved from the upper end position of the inclined slide 382 to the lower end position of the inclined slide 382 and is locked in the positioning concave 383, and the side convex section 344 of the clutch lever 34 is along the convex part. The guiding ramp 385 of the 384 slides in the direction of the pivoting seat 23, the driven element 33 is engaged with the active element 35, and the driving element 35 is driven by the electric motor 31 while the active element 35 is along the driven element 33. The side meshing rotation (like the planetary gears running around the sun gear) causes the thigh bracket 2 to swing relative to the calf support 1 (as shown in Figs. 8 to 10), and the strut mesh 22 of the thigh bracket 2 during the swinging process It is attached to the back side of the thigh, and the thigh is lifted relative to the lower leg, and the user can be converted into a standing posture by the sitting posture, thereby achieving the function of the creation assisted lifting (since the driving shaft 32 is fixedly coupled with the upper end of the middle link 13 of the calf support 1 And the housing 37 of the drive unit 3 Fixed to the pivotal seat 23 with the thigh bracket 2, so most of the components of the drive unit 3 will pivot with the thigh bracket 2 together with the calf support 1, such as the housing 37, the electric motor 31, the tub cover 371, the cover 38 and the clutch Rod 34).

It can be understood from the above description that when the user wears the creative aid, the calf support 1 and the thigh support 2 respectively correspond to the lower leg portion of the human body and the lower leg of the thigh, and the driving unit 3 is controlled to drive the thigh bracket 2 relative to the lower leg bracket. 1 pivoting, the user can assist the sitting thigh relative to the lower leg by the auxiliary device, and then raise the upper body to rise from the low position to the standing high position, and the thigh is pivoted to the slightly straight state relative to the lower leg, in the process Effectively saves the burden on the lower limbs of the user, the user can concentrate on the control of the center of gravity of the upper body, avoiding getting up The danger of self-fall in the process of achieving the purpose and effect of this creation.

For the movable pivoting state of the thigh bracket 2 and the calf support 1, as shown in the fourth, eleventh and twelfth figures, the slip section 343 of the clutch lever 34 is located at the upper end position of the inclined slide 382 (ie, the convexity The block member 381 is on the surface, and the driven member 33 is laterally displaced by the elastic member 36 against the polygonal column segment 321 so that the driven member 33 is not engaged with the active member 35 of the electric motor 31. The lower limb can be arbitrarily swayed, so that the thigh bracket 2 and the calf support 1 cooperate with the lower limb of the human body to pivot and swing, and the lower limbs are not restricted. When the user can swing on the lower limb, the calf support 1 and the thigh support 2 can be respectively associated with the lower leg and the lower leg. The thigh swings without being limited by the pivotal connection of the thigh bracket 2 and the calf bracket 1.

In addition, when the driven member 33 and the active member 35 are to be engaged with each other, the clutch lever 34 and the boss portion 384 are inserted through the clutch lever 34, and only the axial rotation of the clutch lever 34 can be controlled, and the slip is performed in the process. The segment 343 is displaced along the inclined chute 382, and the side convex segment 344 is displaced along the guiding inclined surface 385, so that the rotating wheel 342 is pushed toward the side end of the driven member 33, and the driven member 33 is displaced on the polygonal column segment 321 until the slave is driven. When the element 33 and the driving element 35 are in mesh with each other, and the rotating wheel 342 is pushed against the driven element 33, the rotating wheel 342 is moderately rotated to push against the end surface of the driven element 33, and the rotating wheel 342 is directly pushed against the driven element 33. abrasion.

It is worth mentioning that the present invention can be combined with a control unit 4 in the driving unit 3, as shown in FIG. 13 , and the control unit 4 is electrically connected to the electric motor 31, and the control unit 4 is assembled. A switch 41 for controlling the start and stop of operation of the electric motor 31 is provided, and the user can operate the switch 41 to indirectly perform the pivoting operation of the thigh bracket 2 relative to the calf support 1 and stop the pivoting operation.

In addition, in the embodiment of the present invention, the active element 35 and the driven element 33 are in the form of two helical gears that mesh with each other. The worm and the worm wheel can also be meshed with each other. For example, the active component is a worm, and the driven component is a worm gear. The worm and the worm wheel mesh with each other to rotate, and the thigh bracket can be rotated relative to the lower leg bracket, and the thigh is rotated relative to the lower leg. And stand.

In summary, the "multi-functional accessory for walking and walking" of this creation is indeed practical in terms of structural design and practical use, and the disclosed structural creation is also an unprecedented innovative structure, so it There is no doubt that "novelty" should be considered, and this creation can be more effective than the conventional structure. Therefore, it is also "progressive". It fully complies with the provisions of the new patent application in China's patent law. The bureau proposed a new type of patent application, and requested the bureau to grant the patent right in the case as soon as possible.
