Floor climbing and flat ground dual-purpose bicycle

Abstract

The invention relates to a floor climbing and flat ground dual-purpose bicycle which is characterized by being composed of a frame, a seat saddle, a damping spring, a front wheel, a back wheel, a bicycle chain, a hand brake and a pedal mechanism. Each wheel is composed of a brake disc, a center disc, a center gear, four planet gears and four arc wheel blades, each arc wheel blade and the corresponding planet gear are installed on the center disc through a hinge in a connected mode, a limiting groove is formed in each center disc, the two ends of the limiting grooves are respectively provided with a concave limiting hole, and a limiting spring and a limiting ball are arranged on each center gear. The arc wheel blades rotate around the hinges by a certain angle to enable circular wheels to be converted into impellers, rims of the impellers approach a floor climbing Archimedes helical line corresponding to stair sizes, and floor climbing is accordingly achieved. Compared with other bicycles, the floor climbing and flat ground dual-purpose bicycle has the advantages of being capable of easily and rapidly running on stairs, enabling floor climbing to be safe and increasing riding enjoyment, and can be used for a novel bicycle floor climbing athletics object.

Description

Technical field: [0001] The invention relates to a dual-purpose bicycle for climbing stairs and flat ground, belonging to the technical field of entertainment machinery. Background technique: [0002] With the development of society, the structure and function of bicycles are constantly being improved. At present, the bicycles on the market mainly include mountain bikes, ordinary bicycles, and dual-powered exercise bicycles. The wheels of these bicycles are all designed as round wheels, which are only suitable for driving on flat ground, and driving on stairs is more difficult. Only a few car enthusiasts can ride slowly and bumpy on the stairs. Summary of the invention: [0003] In order to solve the problem that the existing bicycles are difficult to drive on stairs, the technical solution adopted by the present invention is: a dual-purpose bicycle for climbing stairs and flat ground, which is characterized by a frame, a saddle, a shock-absorbing spring, a front wheel, The rear ...

Problems solved by technology

[0003] In order to solve the problem that existing bicycles are difficult to run on stairs, the technical solution adopted in the present invention is: a dual-purpose bicycle for climbing stairs and flat ground, which is characterized in that it consists of a frame, a saddle, a shock absorbing spring, a front wheel, The rear wheel, car chain, hand brake and pedal mechanism are composed. The wheel is composed of a brake disc, a central disc, a central gear, four planetary gears, and four circular-arc vanes. Each circular-arc vane passes through the corresponding planetary gear. The hinge connection is installed on the center plate, and the circular arc vane rotates at a certain angle relative to the center plate to convert the circular wheel into an impeller. The central gear is connected through a hollow half shaft, and the other hollow half shaft is connected with the central disk. The two hollow half shafts are matched with the bicycle axle through bearings. There is a limiting groove on the central disk, and there are A concave limit hole, the sun gear has a limit spring and limit ball
