Description

A kind of foldable full terrain bicycle

Technical field

The utility model relates to a kind of functional bicycles, more particularly to a kind of foldable full terrain bicycle.

Background technique

Full terrain bicycle refers to can be more in paved road, rock hill path, the water surface, sand ground, snowfield, meadow, marsh etc. The special bicycle arbitrarily converted between kind complicated landform, and ridden on its surface, amphibious bicycle etc. common at present, It is more only to be reequiped in the structure basis of ordinary bicycle to ensure that it can ride in required topographical surface, in front and back It takes turns two sides and float is installed, or the hollow wheel that repacking is bigger, vehicle frame wheel can not be folded, excessive tire construction It generally requires special oversize vehicle and transports recreation ground or the dispensing use of dedicated place, be not easy to or even be not available private Family's vehicle-mounted running, unsuitable individual plays or carrying when outing, the scope of application are restricted；

Moreover, the suspension system of amphibious bicycle common at present, is come by the damping effect of wheel itself Realize shock-absorbing, wheel is fixed on vehicle frame, the height of each wheel can not be automatically adjusted according to actual landform or road conditions, On rugged potted road surface or rock hill path when driving, shock-proof effect is less desirable, and handling capacity, which also compares, to be had Limit, influences its scope of application；

Moreover, amphibious bicycle common at present, generally using fixed frame rail between handle and seat The front-rear position of connection, handle and seat is fixed, and when trip, which is played, to be needed to carry, this bicycle structure is not easy to Private car transport, there are inconvenience, and this bicycle structure, it cannot be according to demands such as the figures of user, to handle It is adjusted with the position of seat and spacing, is unable to satisfy the demand comfortably ridden, and the quantity of seat is typically all to fix , it can not be increased and decreased according to actual needs, the scope of application is restricted；

Moreover, amphibious bicycle common at present, usually foot-operated driving rear wheel is ridden, and is suitble in land Ground or the water surface etc. are single and comparatively ideal topographical surface is ridden, and can not freely convert and ride between different terrain surface, or It rides in more severe such as soft sand ground, snowfield, meadow, marsh topographical surface, such as needs to be ridden from the water surface to land On the ground, it or when the topographical surfaces such as soft sand ground, snowfield, meadow, marsh are ridden, since front-wheel does not have driving force, rises and drives The rear-wheel of movement is easy to skid in soft sand ground, snowfield, meadow, marsh in water, can not provide enough drivings Power drives bicycle to move ahead, and influence rides effect；

Moreover, amphibious bicycle common at present, in order to ensure it can ride at a slow speed on different terrain surface, one As be designed as four wheel constructions, but its two pairs of wheel in front and back are all mounted in and rotate synchronously in same root shaft, thus work as four-wheel Bicycle paved road run at high speed need to turn when, or traveling in the topographical surface of out-of-flatness, will be due to inside vehicle Wheel is different from the rolling radius that outboard wheels need, but cannot achieve different revolving speeds, so that wheel is easy to cause to slide Phenomenon is dragged, bicycle is made traveling manipulation difficulty, brake reduced performance, the security risks such as cruising characteristic variation, shadow occur Ring ride effect and riding safety.
