Abstract
A moving body includes: a vehicle which includes a front wheel and rear wheels and which a passenger gets on; an unmanned carrier vehicle which is arranged at the back side of the vehicle, and includes a wheel and a driving unit which drives the wheel; and a coupler which couples the vehicle and the unmanned carrier vehicle. The coupler includes a biasing mechanism which biases a rear part of the vehicle toward an upper side of the vehicle, the biasing mechanism includes a first elastic member; when the passenger is on the vehicle, the first elastic member is deformed by the weight of the passenger to place the rear wheels in contact with a road surface, and when the passenger is not on the vehicle, the rear wheels are separated from the road surface by the elastic force of the first elastic member.
Claims5
A moving body comprising:
- a vehicle that includes one or more front wheels and a plurality of rear wheels;
- an unmanned carrier vehicle that includes a wheel and a driving unit, wherein the driving unit drives the wheel;
- and
- a coupler that couples a rear part of the vehicle and a front part of the unmanned carrier vehicle,
- wherein the coupler includes a biasing mechanism that biases the rear part of the vehicle toward an upper side of the vehicle,
- wherein the biasing mechanism includes a first elastic member,
- wherein in a state in which a passenger is on the vehicle, the first elastic member is deformed by to place the plurality of rear wheels in contact with a road surface,
- wherein in a state in which the passenger is not on the vehicle, the first elastic member separates the plurality of rear wheels of the vehicle from the road surface by the elastic force,
- wherein the coupler includes a first coupling part that is connected to the vehicle, and a second coupling part that is connected to the unmanned carrier vehicle and the first coupling part, the second coupling part is relatively rotatably about the first coupling part around a rotary shaft along a left-right direction of the vehicle,
- wherein one end of the first elastic member is supported by the first coupling part,
- wherein another end of the first elastic member is supported by the second coupling part, and
- wherein the biasing mechanism switches between a state of contacting the plurality of rear wheels with the road surface and a state of apart the plurality of rear wheels from the road surface by relatively rotating the second coupling part with respect to the first coupling part by deformation of the first elastic member.
