Detailed Description
As shown in fig. 1-17, when the tricycle needs to go forward or backward, firstly, the elderly or people with diseases on four limbs are seated on the seat 2 of the tricycle, both hands hold the head 1 of the tricycle, the back of the tricycle is abutted against the swinging backrest 14, the swinging backrest 14 swings back and forth under the double actions of the back and forth swing of the lumbar, the lumbar pressure and the tension of the elastic tensioning rope 36, and the tricycle is driven to go forward and backward by the back and forth swing driving force through the crank rocker backrest mechanism 41, the double-ratchet bevel gear one-way mechanism 40 and the reversing mechanism 43.
When the swinging backrest 14 swings back and forth under the double action of the lumbar vertebra pressure of a person and the tension of the elastic tensioning rope 36, the swinging backrest 14 drives the crank 13 to rotate under the force transmission of the connecting rod 44, and the crank 13 drives the double-bevel gear shaft 9 and the double-meshed bevel gear 18 to rotate through the crank shaft 12, the primary driving bevel gear 11 and the primary driven bevel gear 10.
When the swinging backrest 14 drives the crank 13 to rotate anticlockwise, the double-meshing bevel gear 18 rotates clockwise through meshing transmission of the first-stage driving bevel gear 11 and the first-stage driven bevel gear 10, because both sides of the double-meshing bevel gear 18 are simultaneously meshed with the right ratchet bevel gear 15 and the left ratchet bevel gear 16, at the moment, the right ratchet bevel gear 15 rotates clockwise, the left ratchet bevel gear 16 rotates anticlockwise, and because the right ratchet wheel 20 ensures that the right ratchet bevel gear 15 and the double ratchet shaft 17 rotate clockwise synchronously, the right ratchet bevel gear 15 idles on the double ratchet shaft 17 during anticlockwise rotation, the left ratchet bevel gear 19 ensures that the left ratchet bevel gear 16 and the double ratchet shaft 17 rotate clockwise synchronously, the left ratchet bevel gear 16 idles on the double ratchet shaft 17 during anticlockwise rotation, therefore, the right ratchet bevel gear 15 and the double ratchet shaft 17 rotate clockwise, and the left ratchet bevel gear 16 idles on the double ratchet shaft 17, the double ratchet shaft 17 is driven to rotate clockwise by the right ratchet bevel gear 15.
When the swinging backrest 14 drives the crank 13 to rotate clockwise, the double-meshing bevel gear 18 rotates anticlockwise through meshing transmission of the first-stage driving bevel gear 11 and the first-stage driven bevel gear 10, because both sides of the double-meshing bevel gear 18 are simultaneously meshed with the right ratchet bevel gear 15 and the left ratchet bevel gear 16, at the moment, the right ratchet bevel gear 15 rotates anticlockwise, the left ratchet bevel gear 16 rotates clockwise, and because the right ratchet wheel 20 ensures that the right ratchet bevel gear 15 and the double ratchet shaft 17 rotate clockwise synchronously, the right ratchet bevel gear 15 idles on the double ratchet shaft 17 during anticlockwise rotation, the left ratchet bevel gear 19 ensures that the left ratchet bevel gear 16 and the double ratchet shaft 17 rotate clockwise synchronously, the left ratchet bevel gear 16 idles on the double ratchet shaft 17 during anticlockwise rotation, at the moment, the right ratchet bevel gear 15 idles on the double ratchet shaft 17, the left ratchet bevel gear 16 and the double ratchet shaft 17 rotate clockwise synchronously, the double ratchet shaft 17 is driven to rotate clockwise by the left ratchet bevel gear 16.
No matter the lumbar swing backrest 14 drives the crank 13 to rotate clockwise or anticlockwise, the double-ratchet shaft 17 can be driven to rotate clockwise, and when the double-ratchet shaft 17 rotates clockwise, the power of the double-ratchet shaft drives the lower bevel gear 24 to rotate unidirectionally through the driving bevel gear 27, the upper bevel gear 22 and the reversing transmission shaft 23.
When the lower bevel gear 24 rotates in a single direction, and when the front and rear shift forks 21 are moved to be locked at the left end groove position in the locking groove 29, the front and rear shift forks 21 fix the duplex sliding bevel gear 25 at the leftmost end position through the snap ring 28, at this time, the right end bevel gear of the duplex sliding bevel gear 25 is in meshing transmission with the right end gear of the lower bevel gear 24, the right end bevel gear of the duplex sliding bevel gear 25 drives the duplex sliding bevel gear 25 to rotate anticlockwise, the duplex sliding bevel gear 25 drives the spline shaft 26 and the right wheel 6 and the left wheel 8 at the two ends of the spline shaft to rotate anticlockwise, and at this time, the waist pendulum drives the tricycle to retreat.
When the lower bevel gear 24 rotates in a unidirectional rotation manner, and when the front and rear shift forks 21 are moved to be locked at the right end groove position in the locking groove 29, the front and rear shift forks 21 fix the duplex sliding bevel gear 25 at the rightmost end position through the snap ring 28, at the moment, the left end bevel gear of the duplex sliding bevel gear 25 is in meshing transmission with the left end gear of the lower bevel gear 24, the left end bevel gear of the duplex sliding bevel gear 25 drives the duplex sliding bevel gear 25 to rotate clockwise, the duplex sliding bevel gear 25 drives the spline shaft 26 and the right wheel 6 and the left wheel 8 at the two ends of the spline shaft to rotate clockwise, and at the moment, the waist pendulum drives the tricycle to move forward.
When the lower bevel gear 24 rotates in a unidirectional way, and when the front and rear shift forks 21 are moved to be locked at the middle-end groove position in the locking groove 29, the front and rear shift forks 21 fix the duplex sliding bevel gear 25 at the middle-end position through the snap ring 28, at this time, the left-end bevel gear and the right-end bevel gear of the duplex sliding bevel gear 25 are not meshed with the lower bevel gear 24, the duplex sliding bevel gear 25 is separated from the lower bevel gear 24, at this time, the lower bevel gear 24 is in an idle rotation state, the lower bevel gear 24 cannot drive the spline shaft 26 and the right wheel 6 and the left wheel 8 at the two ends of the spline shaft to rotate, and at this time, the waist swing driving tricycle is in a state.
Namely, when the front and rear shift forks 21 are respectively locked at the left, middle and right positions in the locking grooves 29, the tricycle driven by the waist swing is respectively in three states of retreating, stopping and advancing, the tricycle driven by the waist swing can freely advance and retreat by changing the locking positions of the front and rear shift forks 21, and can flexibly reach a preset position.
