[Prior Art] Human foot pedaling is vivid, common in two-wheelers or sports equipment, such as bicycles and exercise bikes. Such equipment is powered by interactive pedaling, which outputs mechanical energy through the transmission to achieve vehicle travel or motion damping. Known transmissions, such as chain drive or belt drive, mainly include components such as chains, belts, gears or pulleys. Occasionally, during use, unsuccessful use such as chain or idling occurs. SUMMARY OF THE INVENTION The present invention provides a fluid transmission method, which discards a conventional chain drive or a belt drive mechanism, and converts the human body pedaling kinetic energy into mechanical energy by using the fluid of the pipeline as a medium to achieve the purpose of vehicle travel or motion damping.

The fluid returning to the pipeline flows into the motor communicating with the pipeline in the output direction, and the motor shaft rotates to output mechanical energy due to the fluid pressure difference and the flow velocity. Wherein, the fluid of the output motor flows into the oil storage tank along the pipeline, and can be circulated into the cylinder according to the piston pumping. In addition, the fluid flowing through the pipeline is a liquid, and the motor connected to the pipeline is a hydraulic motor. If the fluid flowing through the pipeline is a gas, the motor connected to the pipeline is a pneumatic motor. The invention provides a fluid transmission device which is connected to a cylinder for conveying a fluid, and a crank is respectively connected to both sides of the cylinder body, and the shank end is combined with a pedal; the cylinder body comprises: a plurality of piston chambers, the piston chamber is oriented One end of the center of the cylinder is an open end, and the other end is a closed end; a plurality of pairs of through holes, one end of the through hole is in communication with the piston chamber, and the other end is connected to the pipeline to be closed, and a one-way valve is installed in the hole; a plurality of pistons are inserted into the corresponding piston chambers, the ends of which are pivotally connected to a piston rod; a pair of turntables are mounted on both sides of the cylinder for self-rotation, and the turntables are connected with a crankshaft of 201210887, and the piston rods are used to drive the pistons to reciprocate. A first-class channel is formed between the two through holes of the same purpose, and each of the through holes forms a circulating fluid passage with the flow channel. In addition, an eccentric shaft is coupled between the two turntables; the piston rods are pivotally connected to each other and can be driven by the eccentric shaft to run around the axis of the turntable. The embodiments, structures, and features of the present invention are described in detail below with reference to the accompanying drawings, and the <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; [Embodiment] Hereinafter, related embodiments will be described in detail based on the drawings. Referring to Fig. 1, it can be seen that the fluid transmission method of the present invention is based on the fluid of the pipeline, through the interaction of the pedal interaction 90 and the movement of the piston 92, and the fluid pressure 94 and the flow velocity are generated, thereby driving and rotating the shaft. 96 outputs mechanical energy and finally flows into the oil reservoir 98 (in the pipeline). In this way, the cycle is repeated cyclically to achieve the purpose of vehicle movement or motion damping. In detail, the pedal is continuously rotated according to the human interaction; the piston inside the cylinder is synchronously reciprocated; the fluid is drawn from the pipeline of the communication cylinder, enters the cylinder according to the input direction, and is then pressurized and discharged outside the cylinder. The fluid returning to the pipeline flows into the motor communicating with the pipeline in the output direction. The fluid pressure difference and the flow velocity cause the motor shaft to rotate to output mechanical energy; the fluid of the output motor flows into the oil reservoir along the pipeline, in response to the piston It can be recycled to the cylinder. The fluid contains gas and liquid, and the applicable motor is also divided into hydraulic horse 5 201210887 up to the pneumatic horse, so the pipeline of the delivery (4) is connected to the liquid helium motor, and the pipeline for conveying the gas is connected to the air motor. The fluid transmission device embodied in accordance with the above method is referred to as Fig. 2' which is composed of a rainbow body 2〇, a crank 3〇, a pedal 4〇, a motor %, an oil reservoir 60, and a bureau 7〇. The entire fluid transmission device (9) is mounted on the frame of a bicycle 10, and the pedal is stepped by human force, and the crank 30 transmits the kinetic energy to the cylinder 2〇 for not taking the fluid of the pipe=part and pressurizing the output. To the motor 5 () to generate mechanical energy, to drive a wheel 12 rotary motion, so that the bicycle 1 () travels on the road generation if?

The piston rods 80 are pivoted to the end of the piston 81, and the end of the cylinder 8 is shaped differently from the end of the piston 81 with a connecting portion 82, except that the eccentric shaft 32 is passed through. Outside the middle portion of the connecting portion 82, = other piston rods 8 〇, allowing each piston rod 80 to rotate eccentrically with the turntable 3; 付 i Next, see the inside of the cylinder 2G concave m four semi-closed j 2 丨 ' The corresponding piston 81 is accommodated in the room, and the closed end u is closed in the closed space. 2 2 wall surface, ^ into the through hole 23 'two hole end of the two through the piston chamber 2 hole inside the two: the check valve 24, the other end of the selective connection line 70 or ^ '201210887 for output or A flow passage 25 is formed between the two through holes 23 of the same type of fluid, and the other end of the piston chamber 21 is an open end 26, and the open end 26 of the other piston chamber 21 is communicated with each other at a central portion of the cylinder 20. A space is formed which allows the connecting portion 82 of the piston rod 80 to rotate. When each piston 81 moves toward the open end 26 of the piston chamber 21, the suction of the two through holes 23 of the closed end 22 is uniform, and the flow passage 25 and the tube are drawn through the check valve 24. The fluid entering the piston chamber 21, when the piston 81 moves toward the closed end 22, pressurizes through the one-way valve 24 of the other through-hole 23, and exits the cylinder 20 along the flow passage 25 via the conduit 70. In this way, the flow channel 25 is circulated into and out of the cylinder 20 in response to the movement of the piston, thereby converting the human pedaling kinetic energy into a fluid pressure difference and a flow velocity, and completing the output of the mechanical energy through the motor to achieve the performance of the auxiliary travel. Of course, the piston 81 cooperates with the closed end 22 to form a space seal. The degree is directly related to the fluid's extraction or discharge efficiency. A gasket or other leak-proof component can be placed on the piston 81 to maintain a better tightness. In addition, some sports equipment using interactive pedaling means abandoning the traditional chain. The mechanism of the transmission or the belt transmission, the fluid transmission device of the embodiment is modified, and the function of the human treading kinetic energy is converted into mechanical energy by the fluid as the medium, and the motion damping is obtained to complete the training and fitness function. The above embodiment is only for the invention. It is not intended to limit the invention. Various changes, modifications, and applications derived from the above-described embodiments are within the scope of the invention. 7 201210887 [Simple description of the drawings] Fig. 1 is a flow chart showing the steps of implementing the fluid transmission method of the present invention.
