Referring to fig. 1 to 2, an embodiment of the present invention provides a labor-saving lever bicycle 100, which includes a frame 50, and a wheel mounted on the frame 50, wherein the wheel includes a front wheel 41 and a rear wheel 42. A bracket 30 is fixedly arranged on one side surface of the frame 50, a layer of bracket plate is respectively arranged on two sides of the bracket 30, the inner side bracket plate is close to the rear wheel 42, the outer side bracket plate is far away from the rear wheel 42, and a transmission mechanism 10 and a flywheel 60 are arranged in the bracket 30. The transmission mechanism 10 includes a driven gear 11, a driving gear 12, and a transmission gear 13. The driven gear 11, the driving gear 12 and the transmission gear 13 are duplex spur gears, the driven gear 11 comprises a driven gear large gear 111 and a driven gear small gear 112, the driving gear 12 comprises a driving gear large gear 121 and a driving gear small gear 122, and the transmission gear 13 comprises a transmission gear large gear 131 and a transmission gear small gear 132. The driven gear bull gear 111 abuts against the outboard brace plate, the driven gear pinion gear 112 abuts against the inboard brace plate, the driving gear bull gear 121 abuts against the outboard brace plate, the driving gear pinion gear 122 abuts against the inboard brace plate, the driving gear bull gear 131 abuts against the inboard brace plate, and the driving gear pinion gear 132 abuts against the inboard brace plate. The sector gear 21 meshes with the driving gear pinion 122, the driving gear gearwheel 121 meshes with the transmission gear pinion 132, the transmission gear gearwheel 131 meshes with the driven gear pinion 112, and the driven gear gearwheel 111 meshes with the flywheel 60. The flywheel 60 is mounted against the inboard bracket plate, and the flywheel 60 is fixedly connected to the rear wheel 42 and is capable of driving the rear wheel 42 to rotate. In the present embodiment, the driven gear 11, the driving gear 12, the transmission gear 13, and the flywheel 60 are all mounted on the bracket 30 through a shaft and a bearing. The support 30 is provided with a lever fulcrum 33, the lever fulcrum 33 is rotatably provided with a damping wheel 34, and the working principle of the damping wheel 34 is the same as that of the flywheel 60, namely, the positive stroke does work, and the negative stroke does not do work. The end of the power saving lever 20 with the sector gear 21 is mounted on the damping wheel 34, and the end away from the sector gear 21 is provided with a sawtooth-shaped pedal 22. A bolt 211 is mounted on the sector gear 21, a return spring 212 is hung on the bolt 211, and the other end of the return spring 212 is mounted on the frame 50. The frame 50 is provided with a stopping point 51, and the stopping point 51 protrudes out of the frame 50 and is used for limiting the moving range of the labor-saving lever 20.
When a rider steps on the pedal 22, the labor-saving lever 20 rotates around the lever fulcrum 33 to drive the sector gear 21 to rotate, and further drive the driving gear 12, the transmission gear 13, the driven gear 11 and the flywheel 60 to rotate. Wherein, because the driven gear 11, the driving gear 12 and the transmission gear 13 are duplicate gears, a larger transmission ratio can be generated. When a rider treads the pedal 22 downwards, the labor-saving lever 20 rotates clockwise, the driving gear 12 rotates anticlockwise, the transmission gear 13 rotates clockwise, the driven gear 11 rotates anticlockwise, the flywheel 60 rotates clockwise, and the wheel is driven to rotate clockwise, namely when the rider treads the pedal 22 downwards, the vehicle moves forwards. When the labor-saving lever 20 moves to a certain position, the rider no longer applies force to the pedal 22, the labor-saving lever 20 moves upwards under the action of the return spring 212, and when the labor-saving lever 20 moves to a certain position, the rider treads the pedal 22 again, so that the bicycle can normally move forwards by reciprocating.
In another embodiment, the bracket 30, the labor-saving lever 20, the driving gear 12, the transmission gear 13, the driven gear 11, and the flywheel 60 are symmetrically disposed on both sides of the frame 50 in pairs. When a rider steps on the pedal 22, the labor-saving lever 20 rotates around the lever fulcrum 33 to drive the sector gear 21 to rotate, and further drive the driving gear 12, the transmission gear 13, the driven gear 11 and the flywheel 60 to rotate. Wherein, because the driven gear 11, the driving gear 12 and the transmission gear 13 are duplicate gears, a larger transmission ratio can be generated. When a rider treads the pedal 22 downwards, the labor-saving lever 20 rotates clockwise, the driving gear 12 rotates anticlockwise, the transmission gear 13 rotates clockwise, the driven gear 11 rotates anticlockwise, the flywheel 60 rotates clockwise, and the wheel is driven to rotate clockwise, namely when the rider treads the pedal 22 downwards, the vehicle moves forwards. When the rider steps on the pedal 22 on the other side, the labor-saving lever 20 on the side without force can rotate anticlockwise without hindrance under the tension of the return spring 212 due to the damping wheel 34 and the flywheel 60, and the pedals 22 on the two sides reciprocate so that the labor-saving lever bicycle 100 moves forwards.
Referring to fig. 3, in another embodiment, the labor-saving lever bicycle 100 can further include a pedal mechanism 70. The pedal mechanism 70 comprises a pedal 71, a rotary disc 72 and a rocker 73, wherein one end of the rocker 73 is rotatably connected with the rotary disc 72, the other end of the rocker 73 is rotatably connected with one end of the labor-saving lever 20 far away from the sector gear 21, the pedal 71 is connected with the labor-saving lever 20 through the rocker 73, and the pedal 71 is rotatably arranged on the rotary disc 72. The pedal mechanism 70 and the labor-saving lever 20 form a crank-rocker mechanism, a rider pedals the pedal 71, the pedal 71 drives the turntable 72 to rotate, the rocker 73 is driven to rotate, the rocker 73 drives the labor-saving lever 20 to rotate, and the labor-saving lever 20 transmits power to the rear wheel through the transmission mechanism and the flywheel, so that the labor-saving lever bicycle 100 can move forwards.
The above-mentioned embodiments only represent two embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
