Description

Bicycle driven by connecting rod

This application is that the patent No. is 03138080.8; the date of application is May 27, 2003; the title is a divisional application of "a bicycle driven by a connecting rod".

Technical field

The invention relates to a bicycle, especially a bicycle driven by a connecting rod.

Background technique

Most of the existing bicycles are equipped with handlebars, saddles and front and rear wheels on the vehicle frame. There is a flywheel on the rear wheel. The flywheel and the sprocket are connected with a chain. 180 degree angle, pedals are installed on the crank. When operating, sit on the saddle, hold the handlebar with both hands, and step on the pedal alternately with both feet to drive the rear wheel to rotate and move forward through the sprocket, chain and flywheel. This bicycle has a single function, and the movement of the body is limited during operation.

Contents of the invention

In order to solve the problem of single function and limited movement of existing bicycles, the invention provides a bicycle driven by a connecting rod, which is flexible in operation and highly interesting.

The technical solution adopted by the present invention to solve its technical problems is: install handlebars and front and rear wheels on the vehicle frame, the front wheels are connected to the handlebars as direction wheels, and twisting the handlebars can drive the front wheels to deflect and change the direction of motion. The rear wheel is a driving wheel, and the wheel shaft and the wheel rim are fixed as one, and the wheel shaft is movably installed on the back fork of the vehicle frame, and a pair of cranks with the same length are installed in parallel at the two ends of the wheel shaft. Also on the vehicle frame, a transmission rod is hinged with a hinge shaft, and the transmission rod can be flat or right angled, or can be in other shapes. One end of the transmission rod is equipped with a pedal or a pedal or a seat, and the other end is movably connected with a connecting rod through a movable shaft, and the other end of the connecting rod is movably connected with a crank respectively through a movable shaft. When operating, hold the handlebar to grasp the direction, push the transmission rod with both feet or body pulse, and drive the rear wheel to rotate and move forward through the connecting rod and crank.

The beneficial effect of the present invention is that the transmission rod is pushed hard with both feet or the body pulse, and the rear wheel is driven to rotate through the connecting rod. During operation, the body can move freely and be light and exciting. It can be used as a vehicle or a good key body entertainment equipment.

Example 1:

As shown in Figure 1, the front fork of vehicle frame 1 is equipped with front wheel 2, and front wheel 2 is the direction wheel and is connected with handlebar 4, and twisting handlebar 4 can drive front wheel 2 deflection to change motion direction. Rear wheel 3 is driving wheel, and wheel shaft and wheel rim are fixed as a whole, and wheel shaft is movably installed on the rear fork of vehicle frame 1, and a pair of crank 9 of identical length is installed in parallel at wheel shaft two ends. On the vehicle frame 1, a transmission rod 6 is also hinged with a hinge shaft 5, and the transmission rod 6 is slightly at right angles. The shafts 8 are movably connected with the cranks 9 respectively. Pedal 10 and seat 12 are also installed on the vehicle frame. During operation, hold the handlebar 4 to grasp the direction of motion, first step on the pedal 10 with one foot, and the other pedal provides power to make the car move forward, then sit on the seat 12, and both feet are on the pedal 11 Go up, push pedal 11 before constantly pulse hard, drive rear wheel 3 to rotate and travel forward by transmission rod 6, connecting rod 7 and crank 9.

Example 2:

As shown in Figure 2, the difference of this embodiment relative to Embodiment 1 is that the transmission rod 6 is at a flat angle, and the middle part is hinged to the middle part of the vehicle frame 1 with the hinge shaft 5 and supports a certain height, so that the transmission rod 6 can be like a seesaw Same flexible up and down movement. A pedal 10 is fixed above the transmission rod 6, and the front end of the transmission rod 6 is equipped with a pedal 11, and the rear end is movably connected with the connecting rod 7 with the movable shaft 8, and the connecting rod 7 is movably connected on the crank 9. Both can sit and operate like embodiment 1 during operation, seat 12 can also be rotated 180 degrees, forward to the rear, stand on the two ends of pedal 10 with both feet, step on the two ends of pedal alternately, through connecting rod 7 and crank 9 drives the rear wheel 3 to rotate and travel forward.

Example 3:

As shown in Figure 3, the difference of this embodiment relative to Embodiment 1 is that: one end of the transmission rod 6 is installed with a seat 12, and the other end is movably connected with the connecting rod 7 with the movable shaft 8, and the other end of the connecting rod 7 is movably connected with the crank 9 On the top, the middle part of the transmission rod 6 is hinged on the vehicle frame 1 with the hinge shaft 5 and supports a certain height. During operation, hold the handlebar 4, grasp the direction of motion, step on the pedal 10 with both feet, and sit on the seat 12 with the buttocks, drive the transmission rod 6 with the up and down pulse of the body like riding a horse, and pass the connecting rod 7 and the crank 9 Drive rear wheel 3 to rotate and travel forward.

Example 4:

As shown in Figure 4, the difference of this embodiment relative to Embodiment 1 is that there is no seat, the pedal 10 is installed on the front end of the transmission rod 6, and the rear end of the transmission rod 6 is movably connected with the connecting rod 7 with the movable shaft 8, and the connecting rod The other end of 7 is movably connected on the crank 9, and the middle part of the transmission rod 6 is hinged on the vehicle frame 1 with the hinge shaft 5 and supports a certain height. During operation, hold the handlebar 4 to grasp the direction of motion, stand on the pedal 10 with both feet, and keep jumping up and down. The pulse drives the transmission rod 6 hard, and the rear wheel 3 is driven to rotate forward by the connecting rod 7 and the crank 9.
