Problems solved by technology

The disadvantage is: the front seat (driver's seat) is installed on the front wheel frame, the front seat moves backwards with the front wheel frame when shortened, and the front seat and the rear seat cross contact when shortened to the limit position
This structural design does not achieve the optimal effect of shrinkage, and the shrinkage space and the shrinkage space are not maximized.

Embodiment 2

[0019] In the second embodiment, in the case of installing the telescopic adjustment device 8, a rack and pinion transmission is used. When the tricycle needs to be elongated, first loosen the set bolts below the guide sleeve 71, then shake the rocking bar 83 in the telescopic adjustment device 8, and drive the rack 81 to move outwards through the gears, and the two ends of the rack 81 are connected by the bolts and The two connecting plates 72 at the lower end of the front frame 7 are connected, so the front frame 7 is driven outward by the rack 81, and the front frame 7 stops shaking when it moves to the limit position, and the guide is guided by the tightening bolts below the guide sleeve 71. Cover 71 is fixed on the guide shaft 62 to prevent the tricycle from stretching back and forth when running. Front seat 4 is the driver's seat when using after stretching, and rear seat 5 can carry people. When the tricycle needs to be shortened, it is the same as the above-mentioned ...

Embodiment 3

[0020] In the third embodiment, in the case of installing the telescopic adjusting device 8, a nut screw transmission form is used. The adjustment method is the same as that of the second embodiment above.

[0021] The tricycle of the present invention is shrunk to the optimum, the shrunk space and the shrunk space are fully utilized, it is convenient to turn and move on the road and in the alley, and it is more convenient to store, and it is more convenient to store indoors, avoiding the long-term outdoor exposure that causes electric vehicles damaged and lost.

Abstract

The invention provides an electro-tricycle with frames extensible. The electro-tricycle comprises a front wheel, rear wheels, a handlebar, a front fork, the frames, seats, a battery and a motor differential gear. The frames are composed of a rear frame and a front frame, a front seat and a rear seat are mounted at the upper end of the rear frame, a gap allowing a support rod to move is produced in the middle of the front seat, guide shafts are mounted on two sides of the bottom of the rear frame symmetrically and transversely, and an extension adjusting device is mounted through a fixing plate. The front frame is slidingly connected with the guide shafts through guide sleeves. Electro-tricycle extension and retraction achieve optimal effect, the space structure is effectively utilized, the electro-tricycle is simple in structure, lightweight in use, mobile in case of road and alley entrance turning and easy to store after shortened and can be stored indoors, and damage and loss of the electro-tricycle due to long-time outdoor exposure are avoided.

Description

technical field [0001] The invention belongs to the technical field of transportation tools, and in particular relates to an electric tricycle with a retractable frame. Background technique [0002] At present, with the acceleration of people's life rhythm and the continuous improvement of living standards, electric bicycles have gradually replaced traditional motorcycles by virtue of their advantages such as energy saving, environmental protection and speed. At the same time, electric tricycles have also appeared on the market. Tricycles can generally be used by two or more people, and are an excellent means of transportation for the elderly. However, the electric tricycles in the prior art are generally longer in length, and it is inconvenient to turn on roads and alleys; because the length is longer, it is inconvenient to store indoors, and it is easy to lose or be corroded and aged by the natural environment when stored outdoors for a long time , Seriously affect the se...
