Embodiment Construction

[0026] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0027] A prominent feature of the present invention is to improve the steering structure of the existing short-distance means of transportation, which will be described below first.

[0028] Such as figure 1 and figure 2 As shown, the rotating shaft 16-9 is positioned by the boss at the rotating shaft 9-2, and a deep groove ball bearing 16-6 is installed, and the bearing seat 16-7 is installed on the bearing 16-6, and is positioned by the boss of the bearing seat 16-7. Deep groove ball bearing 16-5, rotating shaft 9-3 place is equipped with shaft fixture 16-10 by boss positioning, and rotating shaft 16-9 two ends are respectively equipped with gasket 16-4 and lock washer 16-3 to prevent each Parts are loose, and the lock washer 16-3 is equipped with round nuts 16-2 to fix respectively. Elastic steel sheet fixing parts 16-1, 16-13 are respectively fixed on t...

Abstract

The invention relates to a foldable tricycle. The foldable tricycle comprises a handlebar (15), a tricycle seat (2), a pedal (5), rear wheels (11), a front tricycle frame (4-1), a rear tricycle frame (4-2) and a steering assembly (16), wherein the steering assembly (16) is connected between the front tricycle frame (4-1) and the rear tricycle frame (4-2) and comprises a rotating shaft (16-9), a bearing seat (16-7), a shaft fixing component (16-10), two deep groove ball bearings, an elastic steel sheet (16-15) and two L-shaped elastic steel sheet fixing components (16-1,16-13); rotating shafts (9) are fixedly connected with the bearing seat (16-7) through a deep groove ball bearings (16-6), a deep groove ball bearing (16-5) is mounted in the bearing seat (16-7), and the shaft fixing component (16-10) is positioned and mounted on the rotating shafts; the elastic steel sheet (16-15) penetrates through the rotating shafts (16-9). The foldable tricycle disclosed by the invention has the advantages that a turning radius is small, the foldable tricycle is not liable to laterally turn, the stability is good, and the foldable tricycle can be folded.

Description

technical field [0001] The invention relates to the field of short-distance transportation tools, in particular to a foldable three-wheeled transportation vehicle, which is not easy to roll over, has a foldable compact shape and a simple operation mode, and has a higher safety factor. technical background [0002] The existing new short-distance transportation tools on the market today include unicycle balance vehicles and two-wheel balance vehicles, all of which rely on the driver's control to maintain the balance of the vehicle body. Serious; while traditional short-distance means of transportation, bicycles, electric vehicles, etc., have the disadvantages of large size, heavy weight, inflexible steering, and inconvenient storage. [0003] Therefore, need a kind of novel short-distance walking-replacing tool to make things convenient for people's life, overcome above shortcoming. Contents of the invention [0004] The invention provides a foldable three-wheeled tricycle...
