Abstract

A carrier including a body and a gravity modulating module disposed at the body is provided. The gravity modulating module includes a weight block, a tilting sensing assembly and a driver. The tilting sensing assembly is adapted for sensing the tilting condition of the body and sending a left turning signal or a right turning signal. The driver is adapted to move the weight block according to the left turning signal or the right turning signal, so that the center of gravity of the carrier shifts to keep balance.

Claims

1. A carrier, comprising:

a body; and

a gravity modulating module disposed at the body, the gravity modulating module comprising;

a weight block;

a tilting sensing assembly adapted for sensing a tilting condition of the body and sending a left turning signal or a right turning signal; and

a driver adapted for adjusting a position of the weight block according to the left turning signal or the right turning signal, so that a center of gravity of the carrier shifts to keep balance.

2. The carrier as claimed in claim 1, wherein the tilting sensing assembly comprises a suspending member and a left touch receiving member and a right touch receiving member disposed at two sides of the suspending member, when the body makes a turn, the suspending member swings and contacts with the left touch receiving member or the right touch receiving member.

3. The carrier as claimed in claim 1, wherein the tilting sensing assembly comprises a conductive ball, a left electric signal receiving member and a right electric signal receiving member, when the body makes a turn, the conductive ball shifts and is adapted to conduct electricity to the left electric signal receiving member or the right electric signal receiving member.

4. The carrier as claimed in claim 1, wherein the tilting sensing assembly comprises a shielding member, a left light receiving member and a right light receiving member, when the body makes a turn, the shielding member shifts to be located above the left light receiving member or the right light receiving member so as to block a light signal.

5. The carrier as claimed in claim 1, wherein the tilting sensing assembly comprises a light emitting device, a left light receiving member and a right light receiving member, when the body makes a turn, the light emitting device shifts to be located above the left light receiving member or the right light receiving member, so that the left light receiving member or the right light receiving member detects a light signal.

6. The carrier as claimed in claim 1, wherein after the left turning signal or the right turning signal is transmitted, the weight block moves in a turning direction.

7. The carrier as claimed in claim 1, wherein when the carrier makes a turn, a total moment of the carrier is zero.

8. The carrier as claimed in claim 7, wherein the total moment of the carrier comprises a gravitational moment of the body, a centrifugal moment of the body, a gravitational moment of the weight block and a centrifugal moment of the weight block.

9. The carrier as claimed in claim 1, wherein the driver comprises a motor, a lead screw, an air cylinder or a hydraulic cylinder.
