Abstract

A gimbal frame includes a guide rod and a locking mechanism mounted at the guide rod. The locking mechanism includes a tightening member disposed at the guide rod, a transmission member disposed at the guide rod and in transmission engagement with the tightening member, an abutting member disposed at one side of the transmission member, and a driving member connected to the abutting member. The transmission member can move in a first direction to drive the tightening member to move in a second direction. The driving member can drive the abutting member to abut the guide rod and to drive the transmission member to move in the first direction.

First claim

What is claimed is:

1. A gimbal frame comprising:
a guide rod; and
a locking mechanism mounted at the guide rod and comprising:
a tightening member disposed at the guide rod;
a transmission member disposed at the guide rod and in transmission engagement with the tightening member, the transmission member being configured to move in a first direction to drive the tightening member to move in a second direction;
an abutting member disposed at one side of the transmission member; and
a driving member connected to the abutting member, and configured to drive the abutting member to abut the guide rod and to drive the transmission member to move in the first direction, wherein:

the guide rod is a first guide rod; and
the gimbal frame further comprises:
a mounting plate slidably disposed at the first guide rod; and
two second guide rods oppositely disposed at two ends of the first guide rod, respectively;

wherein the locking mechanism is configured to lock the mounting plate and the two second guide rods.

2. The gimbal frame according to claim 1 , wherein:
the tightening member is a first tightening member in transmission engagement with one end of the transmission member;
the first tightening member is configured to tighten one of the two second guide rods; and
the locking mechanism further includes a second tightening member in transmission engagement with another end of the transmission member and configured to tighten another one of the two second guide rods.

3. The gimbal frame according to claim 2 , further comprising:
a third guide rod disposed opposite to the first guide rod and located between and connected to the two second guide rods;
wherein the first guide rod, the two second guide rods, and the third guide rod together form a quadrilateral frame body.

4. The gimbal frame of claim 3 , further comprising:
a gravity-center adjustment-and-locking mechanism configured to adjust a gravity center of the gimbal frame, the gravity-center adjustment-and-locking mechanism being arranged at one of the first guide rod, the two second guide rods, and the third guide rod.

5. The gimbal frame according to claim 1 , wherein the tightening member includes an abutting end facing the transmission member and in transmission connection with an end of the transmission member.

6. The gimbal frame according to claim 5 , wherein:
the end of the transmission member includes an inclined surface; and
an end surface of the abutting end includes a slope and is engaged with the inclined surface of the transmission member.

7. The gimbal frame according to claim 1 , wherein:
the driving member comprises a screw joint screwed to the abutting member; and
the driving member is configured to drive the abutting member to abut against the guide rod in response to the screw joint rotating in a predetermined direction.

8. The gimbal frame according to claim 7 , wherein:
the driving member further comprises a connecting section sleeve disposed inside the transmission member; and
the screw joint is disposed at one end of the connecting section.

9. The gimbal frame according to claim 1 , wherein:
the transmission member is accommodated in the guide rod;
the transmission member includes a guide groove; and
the driving member passes through the guide rod and the guide groove to be connected to the abutting member.

10. The gimbal frame according to claim 9 , wherein:
the locking mechanism further comprises a sliding member mounted at the guide groove and accommodated in the guide rod; and
the sliding member is configured to be slidable along the guide groove when the locking mechanism is not locked.

11. The gimbal frame according to claim 1 , wherein:
the abutting member comprises:
a connection member; and
a holding member disposed between the guide rod and the connection member, and being drivingly coupled to the connection member; and

the driving member passes through the transmission member and the holding member.

12. The gimbal frame according to claim 11 , wherein:
the holding member comprises:
a holding surface facing the guide rod; and
an abutting surface disposed opposite to the holding surface and facing the connection member; and

the connection member is configured to abut against the abutting surface in response to the driving member being operated, and the holding surface is configured to grab the guide rod in response to the driving member being operated.

13. The gimbal frame according to claim 11 , further comprising:
a mounting plate connected to the connection member and configured to fix a load;
wherein the driving member is configured to drive the connection member to abut against the mounting plate to lock the mounting plate in response to the driving member being operated.

14. A gimbal comprising:
a gimbal frame configured to carry a load; and
a motor assembly fixed to the gimbal frame and configured to drive the gimbal frame to rotate;
wherein the gimbal frame comprises:
a guide rod; and
a locking mechanism mounted at the guide rod and comprising:
a tightening member disposed at the guide rod;
a transmission member disposed at the guide rod and in transmission engagement with the tightening member, the transmission member being configured to move in a first direction to drive the tightening member to move in a second direction;
an abutting member disposed at one side of the transmission member; and
a driving member connected to the abutting member, and configured to drive the abutting member to abut the guide rod and to drive the transmission member to move in the first direction.

15. The gimbal according to claim 14 ,
wherein:
the guide rod is a first guide rod; and
the tightening member is a first tightening member in transmission engagement with one end of the transmission member;

the gimbal frame further comprising:
two second guide rods respectively connected to two opposite ends of the first guide rod;
wherein:
the first tightening member is configured to tighten one of the two second guide rods; and
the locking mechanism further includes a second tightening member in transmission engagement with another end of the transmission member and configured to tighten another one of the two second guide rods.

16. The gimbal according to claim 14 , wherein:
the driving member comprises a screw joint screwed to the abutting member; and
the driving member is configured to drive the abutting member to abut against the guide rod in response to the screw joint rotating in a predetermined direction.

17. The gimbal according to claim 14 , wherein:
the transmission member is accommodated in the guide rod;
the transmission member includes a guide groove; and
the driving member passes through the guide rod and the guide groove to be connected to the abutting member.
