Description

The present invention relates to a power activation structure for a wheelchair with a power source, and in particular, when a user rotates a manual wheel by hand, a switch is triggered to activate a motor so that the wheelchair with a power source is in an operating state. The present invention relates to a power activation structure for a wheelchair with a power source.

  For people with physical disabilities, the traditional wheelchair is not only a traffic tool but also a healthy one. This is because the movement of the user's arm and body is performed while the user operates the wheelchair by rotating the manual wheel of the wheelchair with both hands, which has an effect of making the user healthy again. In particular, it is not difficult for a user to travel on a gentle road with a conventional wheelchair, but it is difficult to climb a slope. In particular, it is impossible for a user to climb on a slope with an inclination exceeding 15 degrees, and the assistance of others is required.

Under such circumstances, electric wheelchair manufacturers have developed a wheelchair with a power source that can use both human power drive and electric power drive. It is designed so that the electric motor is mounted in the wheel boss of the wheelchair and the activation switch of the electric motor is triggered when the user manually rotates the manual foil. This is proposed, for example, in US Pat. No. 6,230,831, US Pat. No. 5,818,189, US Pat. No. 6,354,390, and US Pat. No. 5,878,829.
Therefore, when the user manually rotates the manual wheel, the activation switch of the electric motor is triggered and the wheelchair is automatically operated.

  In the operation of rotating the motor by triggering the start switch by manual foil, the motor is designed to start when the rotation of the manual foil exceeds a certain angle in order to prevent the motor from being erroneously started due to the movement of the manual foil. . However, if the angle is too large, the motor of the wheelchair tends to feel dull.

  Reference is now made to FIGS. With the configuration of the present invention, when the user manually operates the wheelchair 20 by rotating the manual wheel 100 forward (clockwise) or backward (counterclockwise), the manual wheel 100 rotates the wheel 21. The motor 23 (auxiliary power) is activated by the activation mechanism, and the activation process of the motor 23 will be described in detail below.

  When the user manually rotates the manual wheel 100 forward (clockwise) and operates the wheelchair 20, the coupling end 101 of the manual wheel 100 is coupled to the driving panel 80. Driven by. The rotation range of the drive panel 80 is limited to the restriction hole 84 and the restriction protrusion 34. During the process in which the restricting projection 34 gradually moves to the restricting hole 84, the end of the thick shaft 41 of the first actuating element 40 is moved from the deep end 851 of the first staged sliding groove 85 to the shallow end 852. When the first actuation element 40 reaches the shallow end 852, the first actuation element 40 moves in the direction of the thin shaft 42. Since the first trigger disk 60 is coupled to the thin shaft 42 of the first actuating element 40, the first trigger disk 60 is pushed by the first actuating element 40 and extends outward as shown in FIGS. The extension of the first trigger board 60 triggers the first switch 200 to rotate the motor 23. At this time, the second actuating element 50 is located at the deep end 861 of the sliding groove 86 with the second stage. Therefore, the second trigger board 70 does not extend and the second switch 300 is not triggered.

  Further, when the user operates the wheelchair 20 by manually rotating the manual wheel 100 backward (counterclockwise), the rotation range of the drive panel 80 is limited to the restriction hole 84 and the restriction protrusion 34. During the process in which the restricting projection 34 gradually moves to the restricting hole 84, the end of the thick shaft 51 of the second actuating element 50 is moved from the deep end 861 of the second stepped sliding groove 86 to the shallow end 862, and the second end. When the actuating element 50 reaches the shallow end 862, the second actuating element 50 moves in the direction of the narrow shaft 52. Since the second trigger disk 70 is coupled to the thin shaft 52 of the second actuation element 50, the second trigger disk 70 is pushed by the second actuation element 50 and extends outward as shown in FIGS. The extension of the second triggering board 70 triggers the second switch 300 to rotate the motor 23. At this time, the first actuating element 40 is located at the deep end 851 of the sliding groove 85 with the first stage. Therefore, the first trigger board 60 does not extend and the first switch 200 is not triggered.

  As is clear from the above description, when the user manually rotates the manual wheel, the wheel is driven manually, and the activation mechanism is triggered at the moment when the manual wheel rotates to rotate the motor and output auxiliary power. . In other words, the motor can be activated only when the user manually rotates the manual foil, which has the effect of exercising the arm for the wheelchair user and is not difficult to operate. In particular, when climbing a slope with a wheelchair, the slope can be safely climbed with the wheelchair according to the present invention.

  Reference is also made to FIGS. 12 to 14 and FIG. The drawing shows a second embodiment of the present invention. This simplifies the forward / backward drive mechanism of the first embodiment and has only the forward drive mechanism. The forward drive mechanism includes a set of stepped holes 410, a plurality of actuating elements 420, and a single trigger disk. 430, a plurality of stepped sliding grooves 440, and a switch 450. With the above configuration, the wheelchair according to the second embodiment can only move forward, and when the wheelchair operates, as shown in FIGS. 15 and 17, the end of the actuating element 420 has a stepped sliding groove. When the actuating element 420 reaches the shallow end 442 when the actuating element 420 reaches the shallow end 442, the triggering board 430 is pushed by the actuating element 420 and extends outward. Is triggered to rotate the motor 23. In particular, in the second embodiment, both ends of the recovery spring 460 are respectively engaged with the cover 30 and the drive board 80, and the coupling form of the recovery spring 460 is slightly different from that in the first embodiment, but the drive board 80 is held in the initial position. Has an effect. According to the second embodiment, the wheelchair can only move forward, but the members and the structure are simplified, and can be applied to a lower priced product.

In addition, the switch used in the present invention only needs to be able to turn on and off the circuit. In the present invention, the trigger board is triggered by the switch, and the trigger board rotates together with the wheel. Since it is better to adopt a non-contact type, a proximity switch (PROXIMITY SWITCH) is adopted in the present invention, and the proximity switch is turned on and off when the touch panel approaches the proximity switch.
