Meanwhile, because the lifting of the seat 5 is controlled by the driving mechanism 3, the seat can be adjusted during riding, and further, in order to achieve the purpose of real-time adjustment, during riding, the driving mechanism 3 is reversely trodden to drive the transmission shaft 6 to reversely rotate, so that the movable magnet 7 enables the driving block 8 to be matched with the transmission screw rod 60 through the elastic force of the return spring 9, so that the driving block 8 is driven by the transmission screw rod 60 to synchronously rotate, further the driving piston 11 makes reciprocating motion in the inner wall of the support guide rod 4, so that the air pressure in the support guide rod 4 is increased to ensure the lifting of the seat 5, and meanwhile, in order to reduce the time required by the lifting of the seat 5, the driving piston 11 can be separated from or slightly sit on the seat 5, so that in the process of the upward sliding of the fixed magnet 12, because the pressure applied by the upper end of the driving piston 11 is lower, the upward stroke distance of the driving piston 11 is increased, so that when the driving piston 11 falls down again, the air flow filled in the supporting guide rod 4 is increased, the single lifting distance of the seat 5 is increased, and after the final adjustment is finished, the user sits on the seat 5, so that the air in the supporting guide rod 4 is compressed, meanwhile, the air acts on the driving piston 11, and the driving piston 11 tends to move downwards, and because the downward movement of the driving piston 11 shortens the distance between the fixed magnet 12 and the moving magnet 7, when the moving magnet 7 and the fixed magnet 12 repel each other, the downward force applied by the driving piston 11 can cause the moving magnet 7 to have a certain resistance in the rotating process, and similarly, when the fixed magnet 12 and the moving magnet 7 attract each other, the moving magnet also has a resistance characteristic, so that when the driving mechanism 3 drives the transmission shaft 6 to rotate in the forward direction, because the movable magnet 7 has certain pressure, the driving screw rod 60 can be driven to rotate and the driving block 8 can be separated, so that the movable magnet 7 moves towards one side of the reset spring 9 and compresses the reset spring 9 until the driving block 8 is completely separated from the driving screw rod 60, meanwhile, resistance can not be generated when the driving screw rod 60 rotates in the positive direction, and the purpose of real-time adjustment in the riding process is finally achieved.
Meanwhile, in order to prevent the driving block 8 and the transmission screw rod 60 from being locked in the process of reverse combination, the transmission screw rod 60 and the driving block 8 are in clearance fit, so that the transmission screw rod 60 and the driving block 8 are more easily separated in the process of transmitting torque.
The top of the side wall of the support guide rod 4 is provided with a limit air hole 18 communicated with the inner cavity of the support guide rod 4, and in order to prevent the continuous rising of the adjusting guide rod 16, the side wall of the support guide rod 4 is provided with the limit air hole 18, so that when the seat 5 is ejected to the longest extension length by the air pressure in the support guide rod 4, the air pressure in the support guide rod 4 can be discharged through the limit air hole 18, and the phenomenon of component damage caused by the continuous rising of the air pressure in the support guide rod 4 is avoided.
Wherein, the moving magnet 7 is a ring magnet, and the magnetic poles on the moving magnet 7 are alternately distributed, in order to make the fixed magnet 12 move up and down repeatedly on the support guide rod 4, the moving magnet 7 is set as a ring permanent magnet with the magnetic poles alternately distributed, so that when the moving magnet 7 rotates, the fixed magnet 12 and the moving magnet 12 repeatly repel each other and attract each other repeatedly, and further the fixed magnet 12 drives the driving piston 11 to move up and down repeatedly, thereby providing necessary conditions for increasing the gas flow in the support guide rod 4.
Wherein, the shape of the passive piston 17 is oval, and the inner wall of the supporting guide rod 4 is designed to be an oval inner cavity matched with the passive piston 17, in order to make the seat 5 rotate in the process of adjusting up and down, the passive piston 17 and the adjusting guide rod 16 are designed to be oval tubes, because the adjusting guide rod 16 can only do reciprocating motion up and down on the supporting guide rod 4 in the sliding process, the phenomenon that the riding experience of a user is influenced due to the rotation of the seat 5 is further prevented, meanwhile, the airflow in the supporting guide rod 4 is extruded by the passive piston 17, when the frame 1 moves to a bumpy road section, the user can do synchronous motion by the up-and-down floating of the frame 1, and the discomfort brought to the rider due to bumping can be counteracted by repeatedly extruding the air in the supporting guide rod 4 in the process of moving up and down, and finally preventing bumping.
Wherein, the diameter value of the end surface of the active piston 11 is 2-4 times of the diameter value of the vent hole 10, in order to make the support guide rod 4 have continuous air flow and let out the air flow in the support guide rod 4, the bottom of the frame 1 is provided with the vent hole 10 and is communicated with the outside through the vent hole 10, therefore, when the active piston 11 is moved downwards by the fixed magnet 12, because the aperture value of the active piston 11 is larger than the aperture value of the vent hole 10, and the sealed cavity in the frame 1 is relatively sealed, the air flow in the sealed cavity of the frame 1 can not be let out from the vent hole 10 in a short time, therefore, when the air flow in the frame 1 flows from the active piston 11 to the support guide rod 4, the purpose of pressurizing in the support guide rod 4 is completed, and at the same time, when the air flow in the support guide rod 4 needs to be let out from the active piston 11 subsequently, the air flow can be directly exhausted from the vent hole 10 to the outside, meanwhile, the ventilating hole 10 is positioned at the lowest end of the sealed cavity in the frame 1, so that the phenomenon that the sealed cavity is accumulated with water is also prevented, and the aims of enabling continuous airflow in the support guide rod 4 and enabling the airflow in the support guide rod 4 to be discharged are finally fulfilled.
Wherein, the air release spring 15 is a light spring with small stiffness coefficient, in order to achieve the purpose of automatic falling, the air release spring 15 is arranged at the bottom end of the block 14, and the air release spring 15 is set as a light spring, so that after the use of the seat is finished, the seat 5 can be separated, and further the pressure on the seat 5 can be removed, the air pressure in the support guide rod 4 can be reduced by jacking up the seat 5, if the passive piston 17 is jacked to the limit air hole 18, the pressure can be rapidly relieved through the limit air hole 18, if the passive piston 17 can not reach the height of the limit air hole 18, because of no pressure on the seat 5, the pressure in the support guide rod 4 can be reduced, further the block 14 can not compress the air release spring 15, and the block 14 can be jacked up through the air release spring 15, further the air flow in the support guide rod 4 can be discharged to the sealed cavity in the frame 1 from the air exchange channel 13 in the active piston 11, meanwhile, the air flow is discharged to the outside through the ventilation holes 10, meanwhile, in order to have better riding experience, the situation that the legs of a user are easy to feel sore in the riding process due to the fact that the bending angle of the legs of the user is too large is avoided, the seat 5 can be adjusted to the highest position adapting to the seat through the active piston 11 in the riding process, meanwhile, when the user is about to get off, the user is enabled to be separated from the seat 5 through the pedal driving mechanism 3, then the pressure is relieved by the user due to the fact that the seat 5 has no pressure, the height of the seat 5 is reduced, the user can continue to ride when sitting on the seat 5 again, meanwhile, the legs of the user can be in contact with the ground, and the user can be guaranteed to land stably when getting off.
Wherein, the shape of sprue 14 is the round platform shape, and the round platform top of sprue 14 is located the inner chamber of trading air flue 13, in order to make seat 5 in the in-process that the user took, can press sprue 14 to initiative piston 11 and compress simultaneously the spring 15 that loses air, therefore establish the spring 15 that loses air for the round platform shape, therefore when the pressure in the support guide arm 4 increases, because the air current area of contact of sprue 14 and the support guide arm 4 inner wall is big, therefore more be convenient for close its initiative piston 11, consequently guaranteed the stability of device use.
The outer walls of the active piston 11, the passive piston 17 and the seal bearing 2 mentioned in the present application are all provided with seal rubber rings, and the purpose is to form chambers which are relatively sealed, which can be realized according to the prior art in the field, and thus, the description is not repeated herein.
The working principle is as follows: when in use, the seat is positioned at the lowest position, so the bicycle can be directly ridden;
and (3) adjusting the height in real time: the frame 1 is driven to move forwards by the rotation of the driving mechanism 3, secondly, in the process of the forward movement of the frame 1, the driving mechanism 3 is driven to drive the transmission shaft 6 to rotate reversely by reversely stepping on the driving mechanism 3, the transmission shaft 6 is driven to rotate through the sealed bearing 2, the transmission screw rod 60 is driven to rotate, the movable magnet 7 is driven by the reset spring 9, the driving block 8 at one side of the movable magnet 7 is driven to be combined with the transmission screw rod 60, the driving block 8 is driven to rotate by the transmission screw rod 60 to drive the movable magnet 7 to rotate synchronously, in addition, due to the continuous rotation of the movable magnet 7, the movable magnet 7 and the fixed magnet 12 are driven to repeatedly repel and attract each other, at the moment, in order to increase the adjusting speed of the height of the seat 5, the seat 5 can be lightly seated or separated, and further, in the process that the fixed magnet 12 falls down by the rotation of the movable magnet 7, because the air flow in the sealed cavity of the frame 1 can not be discharged from the ventilating hole 10 in a short time, therefore, the air flow is caused to circulate from the air exchange channel 13 by continuously pressing the fixed magnet 12, the blocking block 14 is jacked up to enable the air flow to enter the inner cavity of the support guide rod 4, the air flow in the support guide rod 4 is continuously increased due to the repeated up-and-down movement of the fixed magnet 12, the adjustment guide rod 16 is further promoted to rise through the passive piston 17, the seat 5 is jacked up finally, then the extending height of the seat 5 is adjusted according to the actual using distance of a user, and then;
riding in the forward direction: after the seat 5 is adjusted, the driving mechanism 3 is rotated forward to drive the driving mechanism 3 to drive the transmission shaft 6 to rotate forward, meanwhile, the frame 1 is driven to move forward by the forward rotation of the driving mechanism 3, because a person sits on the seat, the gas in the cavity of the support guide rod 4 is extruded by the passive piston 17 at the top end of the adjustment guide rod 16, meanwhile, the blocking block 14 extrudes the air escape spring 15 and is closely attached to the active piston 11, and because the gas pressure in the support guide rod 4 is increased by the passive piston 17 in the support guide rod 4, the active piston 11 is pressed to move downward, then, the fixed magnet 12 applies pressure to the movable magnet 7 by magnetic repulsion (magnetic attraction), because the transmission screw rod 60 is rotated forward by the transmission shaft 6, the driving block 8 can extrude the return spring 9 and simultaneously separate from the transmission screw rod 60, so that the forward riding is not influenced, then, carrying out the operation;
bumping and damping: when a user sits on the seat 5, the driven piston 17 extrudes the gas in the inner cavity of the support guide rod 4, so that the gas in the support guide rod 4 is in a relatively compressed state, and then when the frame 1 is in a bumpy road section, the seat 5 continuously and repeatedly extrudes the gas in the support guide rod 4, so that a large-amplitude shock absorption effect is achieved;
the seat falls when waiting to get off: when the user realizes that the user is about to reach the target, the user pushes the driving mechanism 3 to separate from the seat 5, when the seat 5 is not pressed, the seat 5 is lifted by the airflow in the support guide rod 4, meanwhile, the driven piston 17 moves upwards, when the driven piston 17 moves to the topmost end, the limit air hole 18 leaks the airflow in the support guide rod 4, meanwhile, due to the sharp reduction of the pressure in the support guide rod 4, the compressed air release spring 15 enables the blocking block 14 to be ejected by the elastic force, the airflow in the support guide rod 4 is conveyed to the ventilation hole 10 from the ventilation channel 13, the driven piston 17 is slowed down by the self weight of the seat 5, the air release spring 15 cannot be compressed by the self gravity, the airflow in the support guide rod 4 flows out from the ventilation channel 13, and after the seat is lowered to a proper position, the user can ride again, when the user arrives at the destination, the steps of the user are in contact with the ground, when the user leaves, the pressure on the seat 5 is removed, so that the seat 5 can continuously fall until the seat falls to the lowest level, and finally, when the next user uses the seat, the steps are carried out.
