Description

Self-propelled scooter

Technical field:

The utility model relates to a kind of Kickboard Scooter, and particularly a kind of self-propelled scooter with transmission device is applicable to nonirrigated farmland roller-skating motion.

Background technology:

Common Kickboard Scooter mainly is at the rear portion of pedal trailing wheel to be set, and the front portion is provided with on the other hand frame, and hand frame bottom establishes that a front-wheel constitutes.The walking movement person of this common Kickboard Scooter must stand on the pedal by a pin, and the another pin is ceaselessly pedaled and stepped on ground and could drive Kickboard Scooter and advance, and can't realize that the people drives to advance all the time on Kickboard Scooter.

In order to solve the problem voluntarily of Kickboard Scooter, the dealer has disclosed the technical scheme that has their own characteristics each.State Intellectual Property Office's Granted publication in 24 days October calendar year 2001 a kind of " Kickboard Scooter " (notification number is: 2455307) utility model patent, this patent is modified into the pedal of common slide plate the spring plate of arch, between rear axle and trailing wheel, increase by a unidirectional rotation mechanism simultaneously, the power that utilizes human body to shake up and down on pedal makes the pedal anamorphic stretching, tyre tread before and after changing, by described unidirectional rotation mechanism human body up and down float force be transformed into and act on forward thrust on the rear axle, drive Kickboard Scooter and advance.Because the described spring plate extended length that goes up arch is limit, the Kickboard Scooter speed of a motor vehicle is very slow, and interest is not high so object for appreciation is got up, and train on is also undesirable.Seek out the essential human body chatter frequency up and down of accelerating of the desirable speed of a motor vehicle, physical demands is big again, is difficult to realize its commercial object.

State Intellectual Property Office's Granted publication on January 2nd, 2002 a kind of " unidirectional self-propelled scooter " (notification number is: 2468539) utility model patent, this patent replaces the handle of common Kickboard Scooter with described foot control " bearing circle ", with the trailing wheel of the common Kickboard Scooter of described " flywheel " replacement, obtain the power driven Kickboard Scooter with moving forward and backward user's centre of body weight.Obviously, the obtainable power of this mode is very limited, exists above-mentioned identical deficiency not instruct with regard to not saying so.Moreover, this " flywheel " is identical with the effect and the principle of the unidirectional rotation mechanism described in the last patent, this patent utilization moves forward and backward the principle that the gravity center of human body obtains the power driven Kickboard Scooter and can obtain too embodying in last patent so, and only the creator does not express.

Summary of the invention:

In view of prior art exists is to state deficiency, and technical problem to be solved in the utility model is to improve the type of drive of self-propelled scooter, improves Kickboard Scooter speed.

The technical solution that the utility model addresses the above problem is:

A kind of self-propelled scooter, the pedal that comprises front vehicle frame, is located at front-wheel under the front fork, articulates with vertical shaft, the service brake device that has the trailing wheel of mono-directional overrun clutch and be located at trailing wheel top is characterized in that described pedal is by the front running board of trampling for the forward foot in a step with step on the tail skid of pedaling for the rear foot and form; Front-wheel is articulated under the front running board, and front running board is fixed on a vehicle frame front end; Vehicle frame has an extension spring, and the end system of this extension spring is connected under the tail skid, and other end system is connected to the front portion of vehicle frame, is provided with a guiding bindiny mechanism between tail skid and vehicle frame; Trailing wheel is articulated in the rear portion of tail skid.

The both sides that a preferable embodiment of guiding described in the utility model bindiny mechanism is a vehicle frame are provided with parallel channled rail, and both sides are arranged with two rollers respectively below the tail skid, and described roller is embedded in the channled rail.

The both sides that another preferable embodiment of guiding described in the utility model bindiny mechanism is a vehicle frame are provided with parallel dihedral guide rail, and both sides are arranged with two roller set respectively below the tail skid, and the roller clip of described roller set is held on the horizontal sides of dihedral guide rail.

Sporter's bipod is stepped on respectively on the front running board and tail skid of self-propelled scooter described in the utility model, the rear foot is stepped on backward and is pedaled, because trailing wheel is provided with the effect of single overriding clutch, trailing wheel does not change, rear riding force must be delivered on the front-wheel by the forward foot in a step, the elastic force pulling vehicle frame that overcomes extension spring travels forward, in case remove the rear riding force on the tail skid, extension spring just spurs tail skid and travels forward.Repeat above-mentioned action repeatedly, self-propelled scooter one described in the utility model is stretched one and contracted, and car connects the people and travels forward together, and as roller skating, speed is fast, and is interesting strong.

The specific embodiment:
