Abstract

A front driving wheel four-wheel step-slide car comprises a car body, a steering handle and a foot force driven advancing mechanism. The car is characterized in that the car body comprises a main stamping part, a stringer pipe, a beam pipe and a trailing wheel horizontal pipe; the front wheel is used for driving, primary reversing rotation for transmission is realized by the way that a gear fly wheel is meshed with a gear, the two trailing wheels are used as direction wheels, the two front wheels are larger while the two trailing wheels are smaller, the feet is in charge of trample when riding, driving links of the car are less, driving efficient is high, traction is strong, riding is stable and practical, and the car is handy and convenient and is more suitable for the middle-aged and old people to do physical training and ride instead of walk.

Description

Front driving wheel four-wheel step-slide car

Technical field:

The present invention relates to a kind of scooter of standing and trampling up and down, particularly a kind of front driving wheel four-wheel step-slide car.

Background technology:

I have invented a kind of scooter (2006101594430) in 06 year, in 08 year former scooter is improved again, applied for a kind of scooter (2008100401035) again, but the three-wheel scooter has a kind of reliable inadequately sensation regrettably, body-building or short distance for the elderly are ridden instead of walk, and be also not too suitable.

Summary of the invention:

In line with considering, but design a kind of exercise for middle-aged and old customer groups, the instrument that can ride instead of walk as short distance again, and use the front driving wheel four-wheel step-slide car of reliable having peace of mind; The problem that need to solve is, a kind of technology is provided, and guarantees the reliable use of safety, adjusts the structure of former scooter, vehicle body is relaxed and makes the four-wheel shape.

The object of the present invention is achieved like this, front driving wheel four-wheel step-slide car: comprise a vehicle body, a directional bar mechanism, a foot power driven advancing mechanism; It is characterized in that: vehicle body is by forming towards part and pipe fitting and plastic shell, directional bar mechanism is made up of this three part of handgrip, barre and direction linkage, the direction linkage is the version that adopts two four-bar linkage, with handgrip by two four-bar linkage structures two trailing wheels that link, thereby hold and the control scooter before line direction; Foot power driven advancing mechanism, constitute by fix shaft, treadle, step, fork, crank, tooth flywheel, gear, drive wheel, give drive wheel by the direct engaging gear back transfer of the rotation of the tooth flywheel that treadle, fork, crank produced, front driving wheel four-wheel step-slide car is moved ahead.

The invention has the beneficial effects as follows: adopt front driving wheel, make transmission link reduce, transmission usefulness improves, and front-wheel makes deceleration and stopping performance better with bigger wheel, earth-grasping force is stronger, adopt the structure of two four-bar linkage, two steering wheels are arranged on the rear portion, make this car feel both reliable having peace of mind, dexterous again convenient, be more suitable for the elderly's operation.
