Problems solved by technology

[0003] Cars or electric vehicles have become the most widely used means of travel for people. With the development of cities, the increase of vehicles and the reduction of urban space and road space, the problem of parking difficulties will become increasingly prominent. However, ordinary cars or electric vehicles come from the comfort of passengers Considering that the internal space is large, traditional cars or electric cars cannot change their volume, so they take up a lot of space when parking, and it is more difficult to park in the city

Abstract

The invention provides a stretchable trolley frame device which comprises a frame, a swinging frame, a stretchable assembly and two axles. A containing cavity is formed in the rear portion of the frame. The upper end of the swinging frame and the upper end of the containing cavity are hinged. The stretchable assembly comprises a sliding rod and a sliding rail. The sliding rail is arranged on the side wall of the containing cavity. The sliding rod is matched with the sliding rail. The sliding rod and the swinging frame are connected through a first connecting rod. The two axles and the sliding rod are connected through a second connecting rod. The middle of a rocking frame and the swinging frame are hinged, and shock absorbers are arranged between the two sides of the rocking frame and the two axles. When the stretchable trolley frame device is in the retracted device, the sliding rod is operated to move towards the rear portion of the trolley, the swinging frame can be driven and drive the axles to be moved out of the containing cavity, and the internal space of the trolley frame is increased. The invention further provides the stretchable trolley which comprising the stretchable trolley frame device. The stretchable trolley has all the advantages of the stretchable trolley frame device.

Description

technical field [0001] The invention relates to a retractable vehicle frame device. [0002] The invention also relates to a telescopic vehicle. Background technique [0003] Cars or electric vehicles have become the most widely used means of travel for people. With the development of cities, the increase of vehicles and the reduction of urban space and road space, the problem of parking difficulties will become increasingly prominent. However, ordinary cars or electric vehicles come from the comfort of passengers Considering that the internal space is large, traditional cars or electric cars cannot change their own volume, so they take up a lot of space when parking, and it is more difficult to park in the city. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a telescopic vehicle frame device with reasonable structure and capable of changing its own volume. [0005] The technical problem to be solved by the pr...
