Abstract

An elevating apparatus includes a cabin forming an internal space of a vehicle body and a cabin coupling portion including an elevating module coupled to the cabin and raising the cabin from the ground. The elevating module protrudes to the outside of the vehicle body to raise the cabin.

First claim

The invention claimed is:

1 . An elevating apparatus comprising:
a cabin comprising an internal space of a vehicle body; and a cabin coupling portion including an elevating module coupled to the cabin and configured to raise the cabin from a ground, wherein the elevating module protrudes to an outside of the vehicle body to raise the cabin; wherein the elevating module includes: a main elevating unit configured to raise the vehicle body; and an auxiliary elevating unit configured to cause the main elevating unit to protrude to the outside of the vehicle body; and wherein the auxiliary elevating unit includes: a second cylinder coupled to a lower portion of the cabin; and a second piston having one side coupled to the main elevating unit and the other side making a translational motion along the second cylinder.

2 . The elevating apparatus of claim 1 , wherein, when the cabin is not raised or lowered, the main elevating unit is coupled to the vehicle body in a state in which a direction in which a length of the main elevating unit extends is a longitudinal direction of the vehicle body.

3 . The elevating apparatus of claim 1 , wherein the main elevating unit includes:
a first cylinder; and a first piston configured to make a translational motion along the first cylinder.

4 . The elevating apparatus of claim 3 , wherein the auxiliary elevating unit rotates the main elevating unit to protrude outside the vehicle body.

5 . The elevating apparatus of claim 1 , further comprising:
a slot formed with a thread along an outer peripheral surface of the second piston; and a protrusion surrounding the second piston and partially protruding and configured to be inserted into the slot.

6 . An elevating apparatus comprising:
a cabin forming an internal space of a vehicle body; a skateboard platform forming a lower portion of the vehicle body and detachably coupled to the cabin; a cabin coupling portion provided in the cabin and including an elevating module configured to raise the cabin from a ground; and a board coupling portion provided on the skateboard platform and coupled to the cabin coupling portion; wherein the elevating module includes: a main elevating unit configured to raise the vehicle body; and an auxiliary elevating unit configured to cause the main elevating unit to protrude to the outside of the vehicle body; and wherein the auxiliary elevating unit includes: a second cylinder coupled to a lower portion of the cabin; and a second piston having one side coupled to the main elevating unit and the other side making a translational motion along the second cylinder.

7 . The elevating apparatus of claim 6 , further comprising a first coupling portion coupling the cabin coupling portion to the board coupling portion.

8 . The elevating apparatus of claim 7 , wherein the first coupling portion includes:
a lower support portion provided at the board coupling portion protruding toward the cabin coupling portion; and an upper support portion provided at the cabin coupling portion and coupled to the lower support portion.

9 . The elevating apparatus of claim 8 , wherein the lower support portion includes a pressing support portion depressed toward a center along an outer surface, and
the upper support portion further includes a pressing portion configured to press the pressing support portion.

10 . The elevating apparatus of claim 7 , further comprising a second coupling portion configured to align the cabin coupling portion and the board coupling portion.

11 . The elevating apparatus of claim 10 , wherein the second coupling portion is depressed with a predetermined slope.

12 . An elevating apparatus comprising:
a cabin forming an internal space of a vehicle body; a skateboard platform forming a lower portion of the vehicle body and detachably coupled to the cabin; a cabin coupling portion provided in the cabin and including an elevating module configured to raise the cabin from a ground; a board coupling portion provided on the skateboard platform and coupled to the cabin coupling portion; a first coupling portion coupling the cabin coupling portion to the board coupling portion; and a second coupling portion configured to align the cabin coupling portion and the board coupling portion; wherein the second coupling portion further includes: a first insertion portion protruding from the cabin coupling portion toward the board coupling portion; and a first recess portion formed at a lower portion of the board coupling portion at a height corresponding to the first insertion portion.

13 . An elevating apparatus comprising:
a cabin forming an internal space of a vehicle body; a cabin coupling portion coupled to the cabin and including an elevating module configured to raise the cabin from a ground; a driving force generating unit configured to generate driving force capable of driving the elevating module; and a controller configured to control the driving force generating unit; wherein the elevating module includes: a main elevating unit configured to raise the vehicle body; and an auxiliary elevating unit configured to cause the main elevating unit to protrude to the outside of the vehicle body; and wherein the auxiliary elevating unit includes: a second cylinder coupled to a lower portion of the cabin; and a second piston having one side coupled to the main elevating unit and the other side making a translational motion along the second cylinder.

14 . The elevating apparatus of claim 13 , wherein the cabin coupling portion includes first, second, third, and fourth elevating modules, and the controller individually controls driving force of the first, second, third, and fourth elevating modules.

15 . The elevating apparatus of claim 14 , further comprising a detection unit configured to detect an inclination of the cabin, wherein the controller is configured to control at least one of the first, second, third, or fourth elevating modules based on the inclination of the cabin.

16 . The elevating apparatus of claim 13 ,
wherein the auxiliary elevating unit rotates the main elevating unit to protrude outside the vehicle body.
