Description

A hand-cranked scooter

technical field

The invention belongs to a non-motorized scooter, in particular to a hand-cranked scooter.

Background technique

As a necessary means of transportation for people to travel, scooter is widely used in daily life, and there are many types of scooter, such as bicycles, tricycles, electric vehicles, automobiles, etc. However, most of the existing walking-replacing vehicles can only realize a single function of walking instead of walking. With the continuous improvement of people's living standards, people pay more attention to entertainment and fitness, and the single-function walking-replacing vehicles can no longer meet people's needs.

As a fashionable toy car, Longxing car is favored by young people. The hand-cranking exercise is a kind of aerobic exercise, which can play a good fitness effect on people's shoulders, elbows, wrists and other joints. The dragon cart drives the dragon cart by changing the position of the center of gravity by twisting the waist and buttocks left and right. The exerciser holds the handle with one hand or both hands, and rotates clockwise or counterclockwise, so that each joint of the arm can be effectively moved. However, both have certain limitations: the former mainly has certain limitations in speed and the applicable crowd; the latter's simple hand-cranking movement is too monotonous. Therefore, it is of great practical significance to organically combine the motion characteristics of the above-mentioned dragon bike and the body-building function of the lower limbs movement, and develop a new type of scooter integrating entertainment and body-building to serve the public.

Contents of the invention

Aiming at the existing performance limitations, the purpose of the present invention is to provide a hand-cranked scooter. The scooter uses human hand rotation as the power source, and controls the front wheel steering frame through the feet, so that the dragon scooter can slide forward.

To achieve the above object, the present invention adopts the following technical solutions:

A hand-cranked scooter, comprising a pair of rear wheels, a front wheel, a car body, an A-frame, a power transmission mechanism, and a hand-operated mechanism, the front wheels are rotatably connected to the car body through the front wheel frame, A The frame is arranged horizontally, its head is rotatably connected with the car body, and a pair of rear wheels are rotatably connected with the two leg arms of the A frame through a pair of rear wheel frames. The axis line of the rotation shaft of the A-frame leg arm forms an inclination angle with the vertical direction; the hand-operated mechanism is connected with the power transmission mechanism, and the manual mechanism is driven to make the power transmission mechanism swing back and forth, so that the A pair of rear wheels swing back and forth for travel.

Preferably, the hand crank mechanism and the power transmission mechanism include a handle, a rocker, a crankshaft, an incomplete bevel gear a, an incomplete bevel gear b, an A-frame, and a bearing seat; the handle, the rocker, and the crankshaft form a crank rocker In the mechanism, the non-complete bevel gear a and the non-complete bevel gear b mesh with each other, the A-frame is fixedly connected with the non-complete bevel gear b on the vertical plane through a shaft, and a pair of hand cranks are used to alternately shake up and down in the vertical plane to drive and The rocker of the crank rocker mechanism directly connected to the hand crank swings, and then drives the incomplete bevel gear a indirectly connected with the rocker to rotate, and the incomplete bevel gear b directly drives the A-frame to swing back and forth.

Preferably, the hand crank mechanism and the power transmission mechanism include a crank, a guide rod, a slider, a bevel gear a, a bevel gear b, and a pair of handle handles; the hand crank mechanism is connected with a swing guide rod mechanism, and the swing guide The slider of the rod mechanism is slidingly connected with the straight beam at the end of the A-frame, the bevel gear a and the bevel gear b mesh with each other, the bevel gear a is fixedly connected with the horizontal shaft, and the bevel gear b is connected with the vertical shaft Fixedly connected, the bevel gear a and the bevel gear b connected directly or indirectly to the hand crank are driven to rotate through a pair of hand cranks alternately shaking up and down in the vertical plane, and the bevel gear b further drives the crank mechanism of the swing guide mechanism to rotate.

Preferably, the hand crank mechanism and the power transmission mechanism include a turntable, a crank, a guide rod, and a slider; the crank, guide rod, and slider form a swing guide mechanism, and the slider slides with the in-line beam at the end of the A-frame Connection; the turntable is fixedly connected to one end of the crank; the turntable is turned by one hand or both hands, and the A-frame is driven to swing back and forth by the swing guide mechanism.

Preferably, the hand-cranking mechanism and the power transmission mechanism include a turntable, a crank, and a rocker; the crank and the rocker form a crank-rocker mechanism; one end of the rocker is hingedly connected to the horizontal beam at the end of the A-frame; the turntable and the crank One end is fixedly connected; turn the turntable with one hand or both hands, and drive the A-frame to swing back and forth left and right through the crank rocker mechanism.

Preferably, a support wheel frame is also included, one end of the support wheel frame is fixedly connected with the vehicle body, and the other end is rotatably connected with the support wheel.

Further, the opening angle of the A-frame swing arm is α, and the swing range of the A-frame swing arm is within + α/2. The range of α is 60~100 degrees.

Preferably, the opening angle of the swing arm of the A-frame is 100 degrees, and the swing range of the swing arm of the A-frame frame is within + 50 degrees.

Further, the wheel centers of the front wheels are not on the rotation axis of the front wheel frame. With such a structure, the front wheel is a kind of offset wheel, which can also provide forward power while turning the direction, which can compensate for the insufficient power of the rear wheel when it cannot move forward for some reason.

The working principle of the present invention is as follows:

The present invention uses manual rotation as the power source to control the A-frame swing arm to swing left and right. When the swing arm swings, the rear wheel deviates from the equilibrium position and deflects a certain angle around the axis. Due to the inclination angle between the axis of the wheel frame and the vertical direction The wheel tends to return to equilibrium, and the action of the two creates the static friction required for the wheel to move forward. Use your feet to control the direction of the front wheels.

Compared with the prior art, the present invention has the following prominent substantive features and remarkable advantages:

As a new type of scooter, the invention is easy to operate, not only retains the characteristics of light and flexible, leisure and entertainment, but also has the fitness function of hand-rotating movement, and can be used as a transportation tool for the elderly. A scooter that combines leisure and entertainment.
