Description

Last mile mobility with sliding groove folding structure {FOLDING LAST-MILE MOBILITY}

The present invention relates to foldable last-mile mobility, and more specifically, to last-mile mobility in which the front and rear footrests of the footrest can be folded by forming an 'ㄱ'-shaped sliding hole in the hinge of the footrest.

Recently, with the spread of eco-friendly movements, personal transportation has been attracting attention.

Last mile mobility is a term referring to personal electric transportation such as electric bicycles and electric kickboards, and refers to the last means of transportation that can travel the remaining mile to the destination. The need for modern people is increasing because they can quickly and easily travel short distances that are difficult to reach by public transportation such as buses or trains.

In addition, there is a growing trend of people preferring last-mile mobility, which allows them to ride alone outdoors, rather than public transportation, which inevitably involves close contact with an unspecified number of people on their way to and from work.

Automobile companies view last-mile mobility as a link between mobility services, and when last-mile mobility is activated, it will alleviate traffic congestion, reduce fuel consumption and carbon dioxide emissions, reduce ultrafine dust, fine dust, and air pollution, and save travel time. It is expected to increase various social benefits, and is attracting attention as an important alternative transportation method that can be used in areas with poor connectivity to public transportation.

Previously, last mile mobility was bulky and difficult to mount on a car, so it lacked practicality. In order to increase connectivity with automobiles, they must be manufactured small and light.

Figure 5 is a diagram explaining the operation of the hinge according to the present invention.

Referring to Figure 5(a), one side of the hinge body (140F) and the other side of the hinge body (140R) are bound to each other. In order to separate one side hinge body (140F) from the other side hinge body (140R), the push button (142b) provided at the lower part of one side hinge body (140F) is pressed upward. Accordingly, in FIG. 5(b), the other hinge body 140R may be spaced apart from the one hinge body 140F. At this time, the pin on one side of the hinge connection portion 141 moves from one side to the other side in the horizontal hole of the sliding hole 140FH.

Next, as shown in FIGS. 5(c) and 5(d), the other hinge body 140R is rotated with the pin on one side of the hinge connection portion 141 as the center.

Next, in FIG. 5(e), the other hinge body 140R is pressed downward. At this time, one pin of the hinge connection part 141 moves from the upper side to the lower side in the vertical hole of the sliding hole 140FH.

Through this operation of the hinge 140, the rear footrest 130 can be rotated to the upper side of the front footrest 120 and folded. Figure 6 shows the rear footrest being rotated and folded to the upper side of the front footrest.

Meanwhile, a round part is formed on the body 111 of the connecting body 110. When the rear footrest is folded to the upper side of the front footrest, the rear wheel of the rear footrest is located on the upper side of the round part. Accordingly, the upper side of the round portion provides a rear wheel seating space area where the rear wheel of the rear footrest is seated. Reference numeral A in Figure 6(a) indicates the seating space area of the rear wheel.
