In the embodiment of the present invention, the scaffold support 600 is configured to support the rear end of the scaffolding part 300 when the scaffolding part 300 rotates downward so that the scaffolding part 300 does not rotate below a certain height.

The scaffold support 600 is composed of a support 230 provided on either side of the support member 230 and the pedal frame 310 and a cloud 610 provided on the other side facing each other.

Referring to FIG. 4, the rolling part 610 may include a rotation coupling part 611 provided on one of the support member 230 and the pedal frame 310; And a rolling member 613 that is rotatably coupled to the rotation coupling part 611 and is in contact with the support part 620 when the tilting main body 100 is tilted to the left or the right.

In the embodiment of the present invention, the pivot coupling portion 611 may be provided on the other side facing each other with the support portion 620 provided on any one of the support member 230 and the footrest portion 300, in the drawings The rotation coupling part 611 is provided on the scaffolding part 300 and the supporting part 620 is illustrated in the supporting member 230.

In an embodiment of the present invention, the rotation coupling unit 611 may be provided at the lower portion of the pedal frame 310 as an example, and may include a coupling groove 612 formed in a hemispherical shape.

In the exemplary embodiment of the present invention, the rolling member 613 is spherically shaped so that a portion of the coupling groove 612 is exposed to be exposed, and the exposed portion is configured to be in contact with the support 620. Here, some regions of the rolling member 613 exposed from the coupling groove 612, the tilting main body 100 is configured to be capable of rolling movement in contact with the support 620 when the tilting body 100 is tilted left or right.

When the tilting body 100 is tilted to the left or right side, the rear end of the footrest part 300 located on the inclined side moves slightly between the side and the rear, and the rear end of the foothold part 300 located on the inclined opposite side moves slightly between the front and side sides. do. Therefore, the rolling member 613 is configured to be able to move in a rolling state in contact with the support 620 is configured to reduce the frictional stress when the rolling member 613 is moved.

In the embodiment of the present invention, the support 620 is provided in the plate shape on the support member 230 and the elastic member is fixedly coupled to the support 620 portion where the rolling member 613 is in contact. In addition, the rolling member 613 is configured to contact the elastic member when the scaffolding unit 300 rotates downward to reduce the impact and noise generated when the rolling member 613 contacts the support part 620.

The elastic member may be made of urethane rubber having excellent mechanical properties. A soft urethane having a low hardness has a small elastic modulus, and thus the maximum compressive stress occurring at the center of the contact portion is small as the elasticity coefficient is widened, but the rolling member ( There is a problem that the 613 is pressed into the support 620 too deep. The higher the urethane rubber hardness, the higher the elastic modulus and the smaller the strain, but the higher the elastic modulus, the higher the urethane rubber yield strength. Therefore, if the urethane rubber hardness is too high, such as hard urethane, as the contact area becomes very small, high compressive stress may occur at the contact site, which may cause durability problems. Therefore, according to the urethane rubber hardness and the size of the rolling member 613, the maximum compressive stress generated in the center of the portion where the rolling member 613 and the elastic member are in contact with each other and the indentation depth that the rolling member 613 is press-fitted into the support part 620 are In consideration of the fact that the rolling member 613 size and urethane rubber hardness should be determined.

In an embodiment of the present invention, urethane rubber suggests, but is not limited to, Shore hardness A70-95 similar to inline wheel hardness.

When the tilting body 100 is provided with a cloud 610 so that the rear portion of the scaffold 300 moves smoothly when tilting, the impact and noise are generated when the cloud member 613 contacts the support 620. Therefore, the load providing unit 710 is provided to reduce the impact and noise generated when the rolling member 613 is in contact with the support 620.

As described above, as the footrest part 300 decelerates the rotation speed of the footrest part 300 by the load providing part 710 just before the footrest part 300 comes into contact with the support member 230, the footrest part 300 supports the support member 230. In addition to the impact and noise generated when the contact is reduced, the load is applied to the movement of the power transmission member, so that a part of the impact energy generated when the footrest unit 300 comes into contact with the support member 230 causes the driving wheel 120 to move. There is an advantage that the driving efficiency is increased by switching to the rotating direction.
