In addition, as shown in fig. 8, two first through grooves 34 adapted to the first connecting rod 15 are provided on the outer surface of the second mounting box 31, and as the first connecting rod 15 is fixedly connected with the output end of the adjustable telescopic rod 14, and the output end of the adjustable telescopic rod 14 needs to extend or retract to control whether the first friction wheel 16 contacts with the second connecting rod 32, the first through grooves 34 need to be provided to facilitate sliding of the first connecting rod 15, second through grooves 35 parallel to the first through grooves 34 are symmetrically provided on the upper portion of the outer surface of the second mounting box 31, a second rotating rod 36 is movably mounted in an inner cavity of the second through grooves 35, a third friction wheel 37 adapted to the second friction wheel 33 is fixed on the outer surface of the second rotating rod 36, when the second friction wheel 33 contacts with the third friction wheel 37, and when the second friction wheel 33 rotates, the third friction wheel 37 can be driven to rotate, the third friction wheel 37 is connected with the two wheels of the wheelchair 1 through a belt, so that the third friction wheel 37 can drive the two wheels 31 to rotate when the second friction wheel 37 rotates, and the second wheel 31 is provided with a limit mechanism for limiting the inner cavity 38.
As shown in fig. 9 and 10, the limiting mechanism 38 includes a mounting bracket 381 rotationally connected to the second rotating rod 36, one end of the mounting bracket 381 away from the second rotating rod 36 is fixed with a support plate 382 slidingly connected to the top surface of the inner cavity of the second mounting box 31, the support plate 382 is slidably connected to the second mounting box 31, so that the second rotating rod 36 can move back and forth, a second return spring 383 is fixed between one end of the support plate 382 away from the mounting bracket 381 and a side surface of the inner cavity of the second mounting box 31, which is close to the driving motor 12, the second return spring 383 is used for resetting the second rotating rod 36, so that the third friction wheel 37 can be in contact with the second friction wheel 33 without receiving any external force, a mounting groove 384 is formed at the upper end of the support plate 382, a third return spring 385 is fixed at the right side surface of the inner cavity of the mounting groove 384, a guide rod 386 is fixed at the left end of the third return spring 385, and a C groove 386 is formed at the upper end of the second mounting box 31, and C387 is matched with the guide rod 386 is used for limiting the guide groove 387.
As shown in fig. 9, when the third return spring 385 and the second return spring 383 are both in a natural state, the third friction wheel 37 is in contact with the second friction wheel 33, when the guide rod 386 is located in the shorter groove of the C-shaped groove 387, due to the design of the third return spring 385, the guide rod 386 cannot enter the longer groove of the C-shaped groove 387 any more, and further, the shorter groove of the C-shaped groove 387 limits the guide rod 386, and due to the friction between the second friction wheel 33 and the third friction wheel 37, the second friction wheel 33 can provide a force for the mounting bracket 381 to move towards the side close to the second return spring 383 when rotating, and if the mounting bracket 381 is not limited, the second friction wheel 33 does not necessarily drive the third friction wheel 37 to rotate when the device is in use, so that the normal operation of the device is affected.
When the device is used, the guide rod 386 is firstly shifted, so that the guide rod 386 slides in the mounting groove 384, meanwhile, the guide rod 386 slides into the longer groove from the shorter groove of the C-shaped groove 387, then the guide rod 386 is slid, so that whether the third friction wheel 37 is in contact with the second friction wheel 33 or not is controlled, and then the guide rod 386 is limited by entering into the shorter groove of the C-shaped groove 387, when the third friction wheel 37 is in contact with the second friction wheel 33, the second friction wheel 33 can drive the third friction wheel 37 to rotate, and further, the driving motor 12 can drive the two wheels of the rehabilitation wheelchair 1 to rotate through friction between the third friction wheel 37 and the second friction wheel 33 during rotation, so that the wheelchair can move;
When the second friction wheel 33 is not contacted with the third friction wheel 37, the second friction wheel 33 can not drive the wheelchair to move when rotating, meanwhile, if the second mounting box body 31 is contacted with the second friction wheel 33, the wheelchair can also massage the legs of a patient in the process of not moving, meanwhile, when the wheelchair is enabled to move by rotating the wheels of the rehabilitation wheelchair 1, the massaging device 2 can also massage the legs of the patient, so that the wheelchair can exercise the legs of the patient while exercising the arms of the patient, the rehabilitation of the patient is accelerated, and if the second mounting box body 31 is not contacted with the second friction wheel 33, the massaging device 2 can not massage the legs of the patient when the wheelchair is not moving, thereby facilitating the movement of the device.
The specific installation method, circuit connection method and control method of the rehabilitation wheelchair 1, the driving motor 12, the storage battery 13 and the like are all conventional designs, and the invention is not described in detail.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
