The explanation is as follows: Please refer to the first, -, - one, two, four, five 'six diagrams, through the hair (4) (four) μ 'when the user turns the hand to push the ring 〇〇 forward (clockwise direction) or After the counterclockwise rotation, the wheelchair 20 will be selected to pull the main V. The private day inch 'hand push ring 100 will simultaneously drive the wheel 21 to rotate and the motor 23 outputs the auxiliary power by the starting mechanism; The process of starting the motor 23 is as follows: Firstly, when the user has outlined four 1 n.r. 孜 推 推 10 10 for forward driving operation (hand push ring clockwise Θ 3 Μ T universal turn) ), the binding end 1 01 of the hand push ring 1 0 is the same as the driving plate 8 (10) The phase is consolidated, so the driving disk 80 is rotated by the hand pushing ring 100, and the rotation of the disk 80 is restricted by the limiting hole 84 and the limiting protrusion 34. When the limit protrusion 34 is gradually displaced to the limit hole 8 4 - the end of the stroke π ^ 1 is over the private axis, the wide axis 41 end of the first actuator 40 is just from the first class, the code 〇c ^ 1 The position of the deep end 852 of the white, and the α-groove 85 is changed. 11 1291347 is located at the shallow end 851. When the first actuator 4〇 is located in the shallow end 々 actuation area, the first actuator 4〇 is displaced in the direction of the thin axis. Since the first touch pad 60 is fixed to the end of the thin shaft 42 of the first actuator 40, the first touch pad 60 is pushed out by the first actuator 40 (as shown in the seventh and tenth drawings). Shown that the extension of the first-touch plate just cancels the first switch 2 〇〇 to perform the auxiliary power output operation of the motor 23; at this time, the second actuator 5 〇 is located at the second φ P white, 'and 'The inner end of the lunar groove 86 moves within the range of the deep end 862, so that the second touch disc 70 does not extend, and the second switch 3 does not move; further, when the user pulls When the push ring 1〇〇 is operated backward (the operation push ring rotates counterclockwise); the drive: the second rotation of the disk is limited by the limit hole 84 and the limit protrusion 34, when the limit protrusion 34 is gradually displaced to At the same time as the end of the limiting hole 84, the second end of the wide axis 51 of the mover 50 can be changed from the position of the deep end 862 of the second-stage chute 86 to the position of the shallow end 861, when the second actuator 5 is located When the operating end of the shallow end 861, the second actuator 5〇 is displaced in the direction of the thin shaft 52, and the second touch disc 7 is fixed to the thin shaft 52 end of the second actuator 50, so the second touch disc 7〇 will be pushed out by the second actuator 50 (please refer to the eighth and eleventh figures). 'The extension of the second trigger disk 70 can trigger the second switch 300 to act' and the motor 23 assists. The output of the power is running; at this time, in the 12th 1291347:: child: is in the range of the deep end 851 of the first-class chute 85, so that the first touch panel 6〇 will not be activated; The switch 200 not only: "Over the above description, it can be seen that the operator applies the force to push the hand to push the ring, drives the wheel to drive, and pushes The second moment of the ring rotation: the auxiliary power wheel that passes through the starting mechanism and simultaneously makes the motor run out of the auxiliary switch Π = will only be carried out at the same time as the operator's clothes; the wheelchair can be used:: force arm The function of the rehabilitation of the exercise, and the operation: In addition: When the wheelchair is used for the second time, the stone JI is easy to drive uphill through the case. Please refer to the twelfth, +:r, +ro 丄 丄 其 ～ ~ 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十 十The second move of the mover: the plan has only a single group of slots 41〇, a plurality of open _ touch discs 430, a plurality of class chutes 44〇 and - ::45:, which become only forwardable Auxiliary power line level ~ Ding forward driving operation 'actuator 420 can be self-ordering (such as; the deep end 441 relative change to the shallow end "2 actuation shift shown" 'and linkage _ disk 43 〇 stretch sweat 1 50 In this embodiment, the motor 23 outputs an auxiliary motion-1291347 to the 4fin~, and in this embodiment, the reset is specifically performed: the two ends are directly hooked to the structure of the cover 30 and the drive 80 respectively. State, gentleman into ^ ',,,, Ό σ 1 grief and the first embodiment slightly not P 'can also achieve the drive disk 8 〇 to maintain the initial positioning effect ^ This embodiment can only be carried out The wheelchair structure of the auxiliary power is reduced and the components and structure are simplified, and it is suitable for use as a lower cost product. Incidentally, the switch used in the present invention is mainly capable of performing the function of closing and opening the circuit. The case is triggered by the trigger disk, and the touch disk will rotate with the wheel. It is better to use a non-contact type switch. For example, the switch (PR0XIMITY SWITCH) can be used as the switch of the present case. When the touch panel is close to the proximity switch, the proximity switch can perform the opening and closing operation of the switch; The invention is different from the traditional design for directly detecting the thrust value of the user; instead, the user is manually designed to convert the mechanical displacement into mechanical displacement (the touch disk is extended and displaced), and then the mechanical displacement The switch member is activated to start the operation of the auxiliary power; the structural design of converting the manpower into the mechanical displacement is quite simple and the structural strength is good, which is not only beneficial to the industrial production assembly, reduces the failure rate, and reduces the failure rate to 14 1291347, due to The structure is simplified and the operation is more reliable, and the reliability and safety of the use can be improved.
