New description: [New technical field] The creation department is related to bicycles, and more specifically refers to a bicycle pedaling power mechanism. [Prior Art] According to the general bicycle, the bicycle is driven by the feet to perform circular motion and then transmitted to the rear wheel. • However, due to the limited torque that can be generated in this way, there is another type of bicycle that uses the upper and lower steps of the feet to move forward, as shown in Figure 1, which is mainly used for the bicycle's toothed disc 1 Between the crank and the crank 2, a swinging rod 3 and a connecting device 4 are disposed. The rear end of the swinging rod 3 is provided with a ratchet 5, the ratchet 5 is connected to the toothed disc 1, and the connecting device 4 has a pivoting end and a sliding end, the pivoting end is for a pedal 6 to be inserted into the crank 2, and the sliding end is provided with a bearing set 7, the bearing 7 is composed of two coaxially disposed bearings The bearing set 7 is placed in the swinging rod 3; thereby, the user's feet can be stepped on the pedal 6, and the connecting device 4 can be inserted into the swinging rod 3 by the bearing set 7. The reciprocating slip is performed, so that the swinging lever 3 can swing up and down, and the ratchet 1 is driven to rotate by the ratchet 5 to reach the bicycle. However, since the gap between the ratchets 5 is too large, the transmission of power is not smooth enough, and it is easy to generate a power delay, and since the ratchet 5 has a sound, it is liable to cause uncomfortable noise. 3 ^ In addition, when the swinging lever 3 swings up and down to the highest point and the most estimated milk position, the stress of the shifting direction of the soldier will be completely concentrated on the cylinder 2, which is not difficult for you. 7 锉 谨 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 容易 : : : : : : : : : : : One purpose is to provide a white persuasion mechanism that tramples on the car, and its power transmission is smoother. Another object of the present invention is to provide a bicycle structure, and the stability of the basin P rugged power machine is better. Therefore, this creation is to provide a bicycle pedaling power company in the white h white knife mechanism, system, ° between the car and the crank of the car, which mainly contains dreams. The utility model has a swinging rod and a single piece disposed at one end of the swinging rod. The other end of the swinging rod has a plurality of inwardly extending sliding groove rotations, and the one-way rotating member is connected to the toothed disc; The device g - the connecting plate - a stepping bearing and at least the stepping bearing = is placed on the connecting plate for the pedal of the bicycle to pass through the shaft and the shaft of the sliding plate is locked to the crank, the two bearing sets are not Positioned on the same axis, the material receiving group is placed in the sliding groove of the swinging rod, and the connecting plate is located in the through slot +; thereby, when the swinging rod is subjected to the When the pedal is driven by the one-way rotating member, when the shaft is swung up and down, the bearing sets can be slid in the _#, such as reciprocating sliding, so that the one-way steering member of the M411395 drives the sprocket to rotate. Before the bike. In the bicycle pedaling power mechanism, the swinging device further has a cover that is sealed at the sliding slot opening position of the swinging lever to prevent the connecting device from falling out of the sliding slot. In the pedaling power mechanism of the bicycle, the swinging rod has a setting hole at one end side, and the one-way rotating member is disposed in the setting hole to stably and firmly connect the one-way rotating member and the swinging rod. • The above-described bicycle pedaling power mechanism, wherein the one-way rotating member is a one-way bearing to maintain smoothness of power transmission. In the bicycle pedaling power mechanism, the bearing sets are disposed on the connecting plate in parallel with different axial centers to disperse the received stress. The pedaling power mechanism of the above bicycle, wherein each of the bearing sets has at least one bearing to facilitate slippage in the sliding groove. The pedaling power mechanism of the bicycle described above, wherein each of the bearing sets has two bearings on both sides of the connecting plate to maintain the smoothness of the sliding of the sliding groove. The stepping power mechanism of the bicycle, wherein the one-way steering member has an inner ring, an outer ring, a plurality of balls and a spring between the inner ring and the outer ring, the inner ring has an engaging hole, and the engaging hole is One of the gear teeth meshes with the transmission shaft, and the outer ring is connected to the swinging rod. The outer circumferential surface of the inner ring has a plurality of ball grooves arranged at a predetermined interval, and the opposite ends of the ball groove are respectively - deep At the slot end and the shallow slot end, the balls are located in the ball groove of the inner ring. The spring urges the ball toward the shallow groove end. In the pedaling power mechanism of the above bicycle, wherein the swinging lever is swung from the top to the bottom, the ball is biased by the spring to be located on the shallow groove end, and the ball abuts against the inner ring and the outer ring Interacting, the inner ring and the outer ring are synchronously rotated to enable the swinging rod to drive the toothed disc to rotate; when the swinging rod is swung from bottom to top, the ball compresses the spring to be located on the deep groove end. • The inner ring and the outer ring are idling, so that the swing bar does not drive the toothed disc to rotate when it is swung. The connecting device of the present invention has at least two sets of bearing sets that slide in the swinging rod, so that the stress received can be dispersed on each bearing set to avoid the frustration caused by excessive stress concentration, and can make the pedaling It can be more stable without swaying. The one-way rotating member of the present invention adopts a one-way bearing as a component connecting the swinging rod and the toothed disc drive, and can utilize the one-way bearing, the characteristics of positive and negative gapless drop, not only can reduce the loss of power, but also can Let the user not have to step on the air when stepping on, not only (4) stop the dangerous situation, but also reduce the noise generated when using the ratchet.
