a wheel member connected to the steering member and configured to contact a ground surface, and
a coupling member, into which the steering member is inserted, and detachably mounted to the body part,

wherein the body part includes:
a body member configured to receive the cabin at an upper side thereof, and
a protruding member coupled to the body member to protrude toward an outside of the body member, and to which the coupling member is coupled,

wherein the coupling member includes:
a first coupling part extending upwards, and
a second coupling part extending from an upper end of the first coupling part toward the body part,

wherein the steering member is coupled to the first coupling part, and
wherein the protruding member supports a lower surface of the second coupling part upwards.

2. The mobility vehicle platform of claim 1 , wherein the first coupling part contacts an outer side surface of the protruding member, and wherein the second coupling part contacts an upper surface of the protruding member.

3. The mobility vehicle platform of claim 2 , wherein an outer surface of the first coupling part on left and right sides has a partial shape of a cylinder.

4. The mobility vehicle platform of claim 2 ,
wherein a through-hole passes through the first coupling part in an upward/downward direction, and
wherein an upper end of the steering member is inserted into the through-hole.

5. The mobility vehicle platform of claim 1 , wherein the body part comprises:
a wheel cover member disposed on an upper side of the wheel member, the wheel cover member comprising:
an arc shape to surround the wheel member,
a pair of guide parts each having an arc shape when viewed from an outside, the guide parts having a groove recessed inwards and being spaced apart from each other while facing each other, and
a plurality of cover parts disposed between the pair of guide parts, sides of which are inserted into the recesses, and configured to cover the wheel member.

6. The mobility vehicle platform of claim 5 ,
wherein a plurality of recesses are formed to correspond to the plurality of cover parts, and
wherein shapes of the sides of the cover part correspond to shapes of the recesses.

7. The mobility vehicle platform of claim 1 ,
wherein the protruding member includes:
a first protruding member coupled to a left side of the body member, and
a second protruding member coupled to a right side of the body member,

wherein the coupling member includes:
a first coupling member coupled to the first protruding member, and
a second coupling member coupled to the first protruding member, and

wherein the body part further includes a reinforcing member extending in a leftward/rightward direction, the reinforcing member being adhered to the first protruding member, the second protruding member, the first coupling member, and the second coupling member.

8. The mobility vehicle platform of claim 7 ,
wherein the first protruding member includes:
a (1-1)-th protruding member coupled to a front left side of the body member, and
a (1-2)-th protruding member coupled to a rear left side of the body member,

wherein the second protruding member includes:
a (2-1)-th protruding member coupled to a front right side of the body member, and
a (2-2)-th protruding member coupled to a rear right side of the body member,

wherein the first coupling member includes:
a (1-1)-th coupling member coupled to the (1-1)-th protruding member, and
a (1-2)-th coupling member coupled to the (1-2)-th protruding member,

wherein the second coupling member includes:
a (2-1)-th coupling member coupled to the (2-1)-th protruding member, and
a (2-2)-th coupling member coupled to the (2-2)-th protruding member, and

wherein the reinforcing member includes:
a front reinforcing member connected to the (1-1)-th protruding member, the (2-1)-th protruding member, the (1-1)-th coupling member, and the (2-1)-th coupling member, and
a rear reinforcing member connected to the (1-2)-th protruding member, the (2-2)-th protruding member, the (1-2)-th coupling member, and the (2-2)-th coupling member.

9. The mobility vehicle platform of claim 8 ,
wherein the front reinforcing member is adhered to a front surface of the (1-1)-th protruding member, a front surface of the (2-1)-th protruding member, a front surface of the (1-1)-th coupling member, and a front surface of the (2-1)-th coupling member, and
wherein the rear reinforcing member is adhered to a rear surface of the (1-2)-th protruding member, a rear surface of the (2-2)-th protruding member, a rear surface of the (1-2)-th coupling member, and a rear surface of the (2-2)-th coupling member.

10. The mobility vehicle platform of claim 1 , wherein the body part includes:
a seat member disposed on the upper side of the body member and configured such that a passenger is seated thereon, and
a pair of reception members disposed between the body member and the seat member to support the seat member, the pair of reception members being spaced apart from each other in leftward/rightward direction, and
wherein the pair of reception members form a space in which a wiring line is located.

11. The mobility vehicle platform of claim 10 , wherein a pass-hole, through which the wiring line passes, is formed on a side surface of at least one reception member.
