Description

Pedal lever balance bicycle

Technical Field

The utility model mainly relates to the technical field related to bicycles, scooters and other bicycles, in particular to a pedal rod balance bicycle.

Background

In order to facilitate the use of children, most vehicles are designed into a dual-purpose structure of a balance bike and a bicycle. When the balance bicycle is used as a bicycle, a crank and a pedal are required to be correspondingly arranged on the middle shaft, and the crank and the pedal can be detached when the balance bicycle is used as a balance bicycle. In the existing vehicle structure driven by a pedal mode, most of the vehicles are provided with a chain to drive a flywheel to realize power transmission, and the pedal plate needs to rotate in a ring mode to realize the walking of the vehicle. Therefore, when the child is used for playing, the driving mode of the vehicle is single, the force required for driving the vehicle to walk is high, and the interest is low.

SUMMERY OF THE UTILITY MODEL

For solving the not enough of prior art, the utility model discloses combine prior art, set out from practical application, provide a step bar balance bicycle, laborsaving and can increase children's interest of motion when children use.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a pedal lever balance bicycle comprises a frame, a driving shaft, at least one flywheel connected with the driving shaft, a shifting fork connected with the pedal lever and rotating along with the pedal lever, and a section of chain meshed with the flywheel; one end of the chain is connected with an elastic stretching reset piece, and the other end of the chain is connected with the shifting fork through a pull rope.

Further, a fixed pulley is arranged on the frame, and a movable pulley is arranged on the shifting fork;

one end of the pull rope is connected with the chain, and the other end of the pull rope is fixedly connected to the frame through the fixed pulley and the movable pulley.

Furthermore, a mounting seat is arranged on the frame, one end of the shifting fork is rotatably mounted on the mounting seat, and the other end of the shifting fork is provided with the movable pulley.

Further, the pull rope is a steel wire rope.

Further, the elastic extension reset piece is a spring, one end of the spring is connected to the chain, and the other end of the spring is connected to the frame.

Furthermore, still including the pole of stepping on that can the quick detach, step on and can drive after the pole installation the shift fork rotates.

Furthermore, the flywheel sets up two on the frame symmetry, and every flywheel corresponds and is provided with chain, elastic stretch piece that resets, stay cord and shift fork.

Furthermore, two shifting forks on the frame are independently arranged.

The utility model has the advantages that:

1. the utility model discloses when using, after trampling the foot bar, the foot bar drives the shift fork motion, and the shift fork passes through the stay cord and drives the chain and remove, and then the chain drives sprocket drive vehicle walking, after loosening the foot bar, under the elastic stretch piece effect that resets, the foot bar can automatic re-setting, compares in traditional vehicle, and children use laborsavingly, and are interesting high.

2. The utility model discloses combined lever, movable pulley, fixed pulley principle, can make the vehicle more laborsaving when riding, the walking increases, and the drive structural design that both ends are independent tramples the drive alone about, tramples the drive in turn about, tramples the drive in step, about, and operation mode is various, has left the unicity, can satisfy child and dazzle cool psychology.

3. The utility model discloses trample the pole design and be quick detach formula structure, can realize the second switching of bicycle and balance car, the whole car dual-purpose reduces the family spending, saves parking space, reduces the wasting of resources.

fig. 2 is a schematic view of the structure of the present invention.

Reference numerals shown in the drawings:

1. a frame; 2. a drive shaft; 3. a flywheel; 4. a chain; 5. a spring; 6. pulling a rope; 7. a shifting fork; 8. treading the lever; 9. a movable pulley; 10. a fixed pulley; 11. and (7) mounting a seat.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in fig. 1-2, a related structure of a pedal lever balance bicycle according to an embodiment of the present invention is schematically illustrated (in the drawings, only the related structure of the bicycle frame is shown, and some parts such as the corresponding wheel are not shown).

In the vehicle structure provided by the embodiment, the driving mode is mainly improved. The vehicle comprises a frame 1 used by a traditional vehicle, a driving shaft 2 arranged at the rear part of the frame 1, at least one flywheel 3 connected with the driving shaft 2, a shifting fork 7 and a section of chain 4. The chain 4 is not a complete ring, and the chain 4 is engaged with the flywheel 3 for driving the flywheel 3 to rotate when moving, so as to move the vehicle. The fork 7 is used as a driving member for connecting with the stepping rod 8, and the fork 7 can rotate when the stepping rod 8 is stepped. The rotation of shift fork 7 passes through stay cord 6 and transmits chain 4, and then drives chain 4 and remove, and the spring 5 that chain 4 is connected is used for realizing reseing.

Preferably, two sets of the shift fork 7, the flywheel 3, and the like are symmetrically provided in the present embodiment, and the two sets are independent of each other. Each shifting fork 7 is installed on one installation seat 11 through one rotating shaft, the inner end of each shifting fork 7 is fixedly connected with the rotating shaft, the other end of each shifting fork 7 is provided with a movable pulley 9, a fixed pulley 10 is arranged on the frame 1, one end of each pulling rope 6 (steel wire rope) is connected to the chain 4, and the other end of each pulling rope is fixedly connected to the frame 1 through the fixed pulleys 10 and the movable pulleys 9. With the above structure, the movable pulley 9 and the fixed pulley 10 are combined to achieve the effect of saving labor.

In order to conveniently realize the switching of the vehicle between the balance car and the bicycle, the treading rod 8 and the rotating shaft for installing the shifting fork 7 are quickly locked and released through an L-shaped groove, and other quick-dismantling structures can also be adopted. The vehicle is used as a balance car after the treading rod 8 is removed, and is used as a bicycle after being installed.

The vehicle structure that this embodiment provided, during the use, when trample and trample pole 8, trample pole 8 and drive shift fork 7 and rotate, shift fork 7 removes through the undulant stay cord 6 of movable pulley 9, and stay cord 6 drives chain 4 and removes, thereby drives flywheel 3 through chain 4 and rotates and make the vehicle remove, when loosening and trample pole 8, but the structure automatic re-setting under the effect of spring 5. Because the trample structure of both sides sets up independently, consequently can control trample the drive alone, control the alternative trample drive, control the synchronous trample drive, strengthen children's interest of moving, satisfy children and dazzle cool psychology.
