Detailed Description

As shown in fig. 1-10, when the lumbar vertebra twisting scooter needs to be changed from a sitting state to a lying state, the lying electric push rod 26 is powered on to push the inner push rod out to extend, at this time, under the thrust of the lying electric push rod 26, the double-angle color rod 9, the pedal driving rod 12, the pedal transmission rod 13, the pedal connecting rod 16 and the pedal 17 all rotate upwards and anticlockwise around the supporting and rotating pin 10, the pedal 17 is slowly lifted in the rotating process, when the lying electric push rod 26 is lifted to be close to the horizontal position, the lying electric push rod 26 is powered off and self-locked, and the state is maintained.

When the lying electric push rod 26 extends to make the pedal 17 slowly lift up, the double-role rod 9 also simultaneously rotates around the supporting rotation pin 10, because the three-pin rod 7, the transition rod 8, the double-role rod 9 and the seat plate 19 are a set of hinged four-bar mechanism, at this time, because the standing electric push rod 18 is not electrified and is always in a self-locking state, the standing electric push rod 18 always makes the seat plate 19 and the rotation cushion 21 keep in a stable position state, and cannot swing up and down due to the thrust of the lying electric push rod 26, namely, the seat plate 19 is stable and motionless under the locking force of the standing electric push rod 18 and acts as a rack role in the hinged four-bar mechanism, at this time, under the transmission force of the thrust of the lying electric push rod 26 under the transmission force of the transition rod 8, the double-role rod 9 drives the transition rod 8 to rotate with the backrest rotation pin 23, and at the same time, under the transmission force of the backrest connecting rod 6, the transition rod 8 pulls the seat backrest 5 to slowly rotate with the, when the electric push rod 26 for lying down is extended to the maximum value, the backrest 5 of the chair is also rotated to the horizontal position through the multi-rod linkage, the tri-state deformation device 1 for lying down of the waist twisting scooter in the sitting position completes the change from the sitting state to the lying state,

the lumbar vertebra wriggling car of riding instead of walk becomes the process of sitting up state and the state of lying down by sitting up state and is opposite, only need to make the electric power push rod 26 that lies down circular telegram, make inside push rod withdrawal, running-board connecting rod 16 and running-board 17 all rotate clockwise downwards around supporting rotating pin 10, running-board 17 slowly swings down at the rotation in-process, the electric power push rod 26 that lies down shortens to the minimum when swinging down to being close the vertical position, the electric power push rod 26 that lies down cuts off the power supply and auto-lock, keep this state.

While the electric push rod 26 is shortened to make the pedal 17 slowly swing down, the dual-role rod 9 is simultaneously rotated around the supporting rotation pin 10, under the force transmission of the transition rod 8, the double-angle color rod 9 drives the transition rod 8 to rotate by the backrest rotating pin 23, under the force transmission of the backrest connecting rod 6, the transition rod 8 pulls the seat backrest 5 to rotate slowly upwards by taking the backrest rotating pin 23 as the center, when the electric push rod 26 for lying down is shortened to the minimum value, the backrest 5 of the chair is also rotated to be close to the vertical position through the multi-rod linkage, the tri-state deformation device 1 for lying down of the lumbar-twisting scooter for sitting up completes the change from the lying state to the sitting state, at this stage, since the standing electric push rod 18 is not energized and is always in the self-locking state, the standing electric push rod 18 keeps the seat plate 19 and the rotary cushion 21 in the stable position state without swinging up and down by the thrust of the lying electric push rod 26.

When the waist twist scooter needs to be changed from a sitting state to a standing state, the standing electric push rod 18 is electrified and extended, the lying electric push rod 26 is disconnected and self-locked, so under the self-locking of the electric push rod 26, the double-angle rod 9, the pedal driving rod 12, the pedal force transmission rod 13, the pedal connecting rod 16 and the pedal 17 are kept in a stable position state and cannot swing up and down due to the thrust of the standing electric push rod 18, meanwhile, in the process of pushing out the extension of the push rod in the standing electric push rod 18, the thrust of the push rod pushes the seat base plate 19 and the rotating cushion 21 to support the rotating pin 10 to swing up, namely, at the moment, the hinge four-bar mechanism consisting of the three-pin rod 7, the transition rod 8, the double-angle rod 9 and the seat base plate 19 becomes a frame role of the four-bar mechanism because the double-angle rod 9 is fixed under the self-locking of the electric push rod 26, at the moment, under, the hinge four-bar mechanism respectively uses a backrest rotating pin 23, a transition rod rotating pin 25, a pedal plate driving rod 12 and a support rotating pin 10 as rotating pins to rotate, under the connection and action of a backrest connecting rod 6, although the seat plate 19 and the seat backrest 5 rotate relatively, the seat backrest 5 is always maintained in an upright state, namely, the seat backrest 5 always conducts upward translation in an inclined mode, when a standing electric push rod 18 is electrified and extends to the maximum value, through the multi-bar linkage, the seat plate 19 just rotates to the upright state, namely, the seat plate 19, the seat backrest 5 and the pedal plate 17 are all in the upright state, three are approximately in a straight line, and at the moment, the lumbar vertebra twisting scooter sitting-standing lying three-state deformation device 1 completes the change from the sitting state to the standing state.

When the waist twist scooter needs to be changed from a standing state to a sitting state, the standing electric push rod 18 is electrified and shortened, the lying electric push rod 26 is disconnected and self-locked, so under the self-locking of the electric push rod 26, the double-angle rod 9, the pedal driving rod 12, the pedal force transmission rod 13, the pedal connecting rod 16 and the pedal 17 are kept in a stable position state and cannot swing up and down due to the thrust of the standing electric push rod 18, meanwhile, in the process of shortening the push rod in the standing electric push rod 18, the tension pulls the seat plate 19 and the rotating cushion 21 to support the rotating pin 10 to swing down, namely, the hinged four-bar mechanism consisting of the three-pin rod 7, the transition rod 8, the double-angle rod 9 and the seat plate 19 is fixed to be a frame role of the four-bar mechanism under the self-locking of the electric push rod 26, at the moment, under the tension of the standing electric push rod 18, the four-bar hinge mechanism rotates by using the backrest rotation pin 23, the transition lever rotation pin 25, the pedal drive lever 12 and the support rotation pin 10 as rotation pins, and the seat backrest 5 is always maintained in an upright state, that is, the seat backrest 5 always makes a downward oblique translation, although the seat plate 19 and the seat backrest 5 are relatively rotated under the connection and action of the backrest connecting rod 6.

When the standing electric push rod 18 is electrified and shortened to the minimum value, the seat plate 19 just rotates to the horizontal state through the multi-rod linkage, namely the seat plate 19, the seat backrest 5 and the pedal plate 17 all form a Z-shaped state, and at the moment, the lumbar-twisting scooter sitting-station three-state lying deformation device 1 completes the change from the standing state to the sitting state.
