Abstract
A collapsible cart system, comprising: a container having a front end and a back end, a chassis coupled with a bottom of the container, at least one first leg having a first end movable relative to the chassis and a second end, at least one first wheel coupled with the second end of the first leg, and a first actuator connected to the chassis and the first leg. The first actuator is configured to move the first leg relative to the chassis to alternate between a first position where the second end the first leg is fully extended away from the chassis and a second position where the first leg is substantially parallel with a bottom of the chassis.

A collapsible cart system, comprising:
- a container having a front end and a back end;
- a chassis coupled with a bottom of the container;
- a first leg having a first end movable relative to the chassis and a second end;
- a first wheel coupled with the second end of the first leg;
- a first actuator connected to the chassis and the first leg, wherein the first actuator is configured to move the first leg relative to the chassis to alternate between a first position where the second end the first leg is fully extended away from the chassis and a second position where the first leg is substantially parallel with a bottom of the chassis;
- a power supply electrically coupled with the first actuator, the first actuator draws power from the power supply to move the first leg between the first position and the second position;
- and
- a first sensor disposed on the chassis and below the container, the first sensor being electrically coupled with the first actuator, wherein the first sensor is configured to detect a distance between the first sensor and a surface below the first sensor, the first sensor instructs the first actuator to move the first leg from the first position to the second position when the distance detected is less than a set value.
An automated collapsible cart system, comprising;
- a container having a front end and a back end;
- a chassis coupled with a bottom of the container;
- at least one first leg having a first end movable relative to the chassis and a second end;
- at least one first wheel coupled with the second end of the first leg;
- a first actuator connected to the chassis and the first leg, wherein the first actuator is configured to move the first leg relative to the chassis to alternate between a first position where the second end of the first leg is fully extended away from the chassis and a second position where the first leg is substantially parallel with a bottom of the chassis;
- and
- a first sensor disposed on the chassis and below the container, the first sensor being electrically coupled with the first actuator, wherein the first sensor is configured to detect a distance between the first sensor and a surface below the first sensor, the first sensor instructs the first actuator to move the first leg from the first position to the second position when the distance detected is less than a set value.
A method of manufacturing a collapsible cart system, comprising the steps of:
- providing a container having a front end and a back end;
- coupling a chassis with a bottom of the container;
- connecting a first actuator to the chassis;
- coupling the first actuator with a first leg having a first end movable relative to the chassis and a second end;
- coupling a wheel to the second end of the first leg;
- configuring the first actuator to move the first leg relative to the chassis to alternate between a first position where the second end the first leg is fully extended away from the chassis and a second position where the first leg is substantially parallel with a bottom of the chassis;
- electrically coupling a power supply to the first actuator;
- configuring the first actuator to draw power from the power supply to move the first leg between the first position and the second position;
- disposing at least one first sensor on the chassis and below the container;
- electrically coupling the first sensor with the first actuator;
- and
- configuring the first sensor to detect a distance between the first sensor and a surface below the first sensor, wherein the first sensor instructs the first actuator to move the first leg from the first position to the second position when the distance detected is less than a set value.
