[0023] In a specific embodiment of this application, the first support 1 includes a first support shell 14 and a second support shell 15, which are detachably connected; after the first support shell 14 and the second support shell 15 are spliced ​​together, a receiving space is formed, and the connection end of the rotary drive device 3 to the first support 1 and the connection end of the connecting bearing assembly 4 to the first support 1 are disposed in the receiving space.

[0024] In a specific embodiment of this application, the rotary drive device 3 can be a drive motor or a drive motor.

[0025] In a specific embodiment of this application, the first support shell 14 is the inner side close to the second support 2, and the second support shell 15 is the outer side away from the second support 2.

The diameter of the connecting hole 131 is larger than the assembly shaft diameter of the connecting bearing assembly 4, thereby providing fault tolerance space for the assembly of the second bracket 2, ensuring that the rotary drive device 3 and the connecting bearing assembly 4 can be coaxially set during the assembly of the second bracket 2 and the first bracket 1, and improving the operational stability of the gimbal bracket.

[0027] In a specific embodiment of this application, the diameter of the connecting hole 131 is larger than the assembly shaft diameter of the connecting bearing assembly 4, which can affect the assembly process between the connecting bearing assembly 4 and the first bracket 1; after the connecting bearing assembly 4 and the first bracket 1 are assembled, the assembly position of the connecting bearing assembly 4 and the first bracket 1 is locked.

[0028] In a specific embodiment of this application, the diameter of the connecting hole 131 is 0.01-0.03 mm larger than the assembly shaft diameter of the connecting bearing assembly 4; preferably, the diameter of the connecting hole 131 is 0.02 mm larger than the assembly shaft diameter of the connecting bearing assembly 4.

[0029] In this embodiment of the application, the connecting bearing assembly 4 includes a connecting shaft 41, a bearing base 42, and a bearing 43. The bearing 43 is sleeved on the connecting shaft 41, and the bearing base 42 is sleeved on the bearing 43. The bearing base 42 includes a bushing portion 421 that passes through the connecting hole 131 and a connecting portion that is connected to the first bracket 1. The outer diameter of the bushing portion 421 is the assembly shaft diameter.

[0030] In a specific embodiment of this application, the connecting shaft 41 rotates relative to the bearing base 42 via the bearing 43, so that the second bracket 2 rotates relative to the third connecting end 13 of the first bracket 1 via the bearing 43 assembly.

[0031] In a specific embodiment of this application, after the bearing base 42 is sleeved on the bearing 43, the outer diameter of its bushing portion 421 is the shaft diameter that mates with the connecting hole 131. That is to say, the diameter of the connecting hole 131 is larger than the outer diameter of the bushing portion 421.

[0032] In a specific embodiment of this application, the connecting part may be disposed within the accommodating space or between the second bracket 2 and the first bracket shell 14.

[0033] In this embodiment of the application, by configuring the bearing 43 assembly to connect the shaft 41, the bearing base 42 and the bearing 43, the flexibility of the second bracket 2 to rotate relative to the first bracket 1 is ensured.

[0038] In a specific embodiment of this application, the first bracket housing 14 is provided with a plurality of threaded holes that match the plurality of fixing holes 423. After the screw passes through the fixing hole 423, it engages with the threaded hole to press the snap-fit ​​panel 422 onto the first bracket 1, thereby completing the connection between the snap-fit ​​panel 422 and the first bracket 1.

[0039] In this embodiment, the snap-fit ​​panel 422 is connected to the first bracket 1 through multiple fixing holes 423 and multiple threaded holes, thereby improving the connection stability between the bearing 43 assembly and the first bracket 1.

[0040] In a specific embodiment of this application, the diameter of the fixing hole 423 is larger than the diameter of the threaded hole, so that even when the connecting bearing assembly 4 and the connecting hole 131 are misaligned and finely adjusted, the snap-fit ​​panel 422 and the first bracket 1 can still be pressed and locked together by screws and threaded holes.

[0041] In this embodiment, the connecting bearing assembly 4 further includes a bearing pressure plate 45, which is fixedly connected to the snap-fit ​​panel 422.

[0044] In this embodiment, the connecting bearing assembly 4 further includes a bearing locking member 44, which is fixedly connected to the connecting shaft 41; the bearing 43, the snap-fit ​​panel 422, the bearing pressure plate 45 and the bearing locking member 44 are assembled in sequence.

[0045] In this embodiment, the bearing 43 locking is used to fix the inner ring of the bearing 43 onto the shaft, thereby improving the connection stability of the bearing 43 assembly and improving the coaxiality of both sides of the second bracket 2.

[0046] In this embodiment, the first connecting end 11, the second connecting end 12, and the third connecting end 13 are arranged in a triangle.

[0047] In a specific embodiment of this application, the first connecting end 11, the second connecting end 12, and the third connecting end 13 are arranged in an isosceles triangle with the first connecting end 11 as the vertex.

[0048] In this embodiment, the first bracket 1 is a U-shaped bracket.

[0049] In this embodiment of the application, the first connecting end 11 is disposed on the crossbeam of the U-shaped bracket, and the second connecting end 12 and the third connecting end 13 are respectively disposed on both sides of the U-shaped bracket.

[0050] The gimbal bracket in this embodiment has the following beneficial effects: By setting a rotary drive device 3 and a connecting bearing assembly 4 on both sides of the second bracket 2, and setting a connecting hole 131 on the third connecting end 13 of the first bracket 1 that matches the rotation shaft of the rotary drive device 3, the diameter of the connecting hole 131 is larger than the assembly shaft diameter of the connecting bearing assembly 4, thereby providing fault tolerance space for the assembly of the second bracket 2, ensuring that the rotary drive device 3 and the connecting bearing assembly 4 can be coaxially set during the assembly of the second bracket 2 and the first bracket 1, and improving the operational stability of the gimbal bracket.
