Abstract

A gimbal structure includes a camera assembly. The gimbal structure also includes a first motor configured to drive the camera assembly to rotate around a first rotation axis. The first motor includes a first stator. The first stator includes a first signal control cable. The gimbal structure also includes a second motor configured to drive the camera assembly to rotate around a second rotation axis perpendicular to the first rotation axis. The second motor includes a second stator. The second stator includes a second signal control cable. The gimbal structure further includes a motor housing configured for mounting the first stator and the second stator. The first signal control cable and the second signal control cable are combined to form a first cable structure.

First claim

What is claimed is:

1. A gimbal structure, comprising:
a camera assembly;
a first motor configured to drive the camera assembly to rotate around a first rotation axis, the first motor comprising a first stator, the first stator comprising a first signal control cable and a first cable entry port;
a second motor configured to drive the camera assembly to rotate around a second rotation axis perpendicular to the first rotation axis, the second motor comprising a second stator, the second stator comprising a second signal control cable and a first cable exiting port;
a first connector disposed between the first cable exiting port and the first cable entry port; and
a motor housing configured for mounting the first stator and the second stator,
wherein the second signal control cable extends out of the second stator through the first cable exiting port, and extends into the first stator from the first cable entry port through the first connector to combine with the first signal control cable to form a first cable structure.

2. The gimbal structure of claim 1 ,
wherein the motor housing comprises a first housing disposed along the second rotation axis and a second housing disposed at a first end of the first housing along the first rotation axis,
wherein the first housing comprises a first mounting member configured for mounting the first stator, and
wherein the second housing comprises a second mounting member configured for mounting the second stator.

3. The gimbal structure of claim 2 ,
wherein the first motor comprises a first rotor and a first motor shaft,
wherein the first mounting member comprises a first receiving member configured to receive the first rotor,
wherein the second motor comprises a second rotor and a second motor shaft, and
wherein the second mounting member comprises a second receiving member configured to receive the second rotor.

4. The gimbal structure of claim 3 ,
wherein the first rotor is configured to protrude out of the first housing from the first receiving member, and
wherein the motor housing comprises a third housing covering the first rotor and connected with the first motor shaft.

5. The gimbal structure of claim 3 ,
wherein the motor housing comprises a fourth housing disposed at a second end of the first housing along the first rotation axis, and
wherein the camera assembly is disposed between the second housing and the fourth housing, and is connected with the second motor shaft.

6. The gimbal structure of claim 1 ,
wherein the first connector comprises a first connecting port and a second connecting port connected with one another,
wherein the first connecting port is disposed on the first stator and connected with the first cable entry port, and
wherein the second connecting port is disposed on the second stator and connected with the first cable exiting port.

7. The gimbal structure of claim 1 ,
wherein the camera assembly comprises a camera signal control cable,
wherein the gimbal structure further comprises a second connector disposed on the first stator, and
wherein the first cable structure extends out of the first stator through the second connector and combines with the camera signal control cable to form a second cable structure.

8. The gimbal structure of claim 7 ,
wherein the camera assembly comprises a camera cable exiting port, and
wherein the camera signal control cable extends out of the camera assembly from the camera cable exiting port.

9. The gimbal structure of claim 1 ,
wherein the first rotation axis is a roll axis of the gimbal structure, and the second rotation axis is a pitch axis of the gimbal structure.

10. A gimbal structure, comprising:
a camera assembly comprising a camera signal control cable;
a first motor configured to drive the camera assembly to rotate around a first rotation axis, the first motor comprising a first stator, the first stator comprising a first signal control cable;
a second motor configured to drive the camera assembly to rotate around a second rotation axis perpendicular to the first rotation axis, the second motor comprising a second stator, the second stator comprising a second signal control cable;
a first connector disposed between the first stator and the second stator;
a second connector disposed on the first stator; and
a motor housing configured for mounting the first stator and the second stator,
wherein:
the second signal control cable is combined with the first signal control cable through the first connector to form a first cable structure, and
the first cable structure extends out of the first stator through the second connector and combines with the camera signal control cable to form a second cable structure.
