[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0032] At present, the mainstream turntable structures at home and abroad are indirect transmission structures. Indirect transmission is mainly represented by synchronous belt transmission. Synchronous belt transmission can well ensure the strength of the yaw shaft, but there are also the following problems:

[0033] 1. The installation is complicated and the accuracy is difficult to guarantee. Since the synchronous belt is easy to strip, it needs to have a strong tensioning requirement. Under normal circumstances, the synchronous belt itself has stress, which will exert a constant force in the radial direction of the yaw axis, causing the turntable to deflect in the roll direction, seriously affecting the stability of the turntable during high-speed rotation.

[0034] 2. The service life is short and the loss is large. After the synchronous belt is driven at high speed for a long time, the belt will wear out and the transmission effect of the yaw shaft will be affected.

[0035] 3. It takes up a large space, affects the center of gravity of the turntable as a whole, requires more parts to be installed, and increases the complexity of the overall design.

[0036] Based on the above problems, the inventors have designed and proposed the turntable structures of the following embodiments of the present application to solve the above technical problems.

[0037] As shown in FIG. 1 and FIG. 2, in one embodiment, a turntable structure 10 is provided, comprising a rotating platform 100, a driving member 200 and a brush slip ring 300. The rotating platform 100 is used to install electronic devices and is provided with a first mounting hole 110. The driving member 200 is transmission-connected to the rotating platform 100 so as to be able to drive the rotating platform 100 to rotate. The driving member 200 is provided with a second mounting hole 210, and the second mounting hole 210 is configured to be connected to the first mounting hole 110 to form a mounting channel when the driving member 200 is transmission-connected to the rotating platform 100. The brush slip ring 300 is located at the mounting channel and is connected to the rotating platform 100. The brush slip ring 300 is used to be electrically connected to the electronic device.

[0038] In the turntable structure 10 in the above embodiment, the driving member 200 is directly coupled with the rotating platform 100, omitting the intermediate transmission link, reducing maintenance costs and downtime, reducing energy loss during the transmission process, and improving the transmission efficiency of the turntable structure 10. At the same time, it can also avoid the cumulative error caused by the intermediate transmission affecting the final positioning accuracy, that is, the present application can achieve high-precision positioning control of the turntable structure 10 by accurately controlling the rotation speed and position of the driving member 200. In addition, the use of a hollow driving member 200 with a brush slip ring 300 ensures that the wiring harness of the electronic device on the rotating platform 100 will not be affected by continuous rotation, thereby improving the reliability of the turntable structure 10.

[0039] The driving member 200 may be any driving structure with a hollow hole in the prior art.

[0040] It should be noted that the brush slip ring 300 is detachably connected to the rotating platform 100 , so that the rotating platform 100 can be matched with different types of brush slip rings 300 , thereby expanding the application scenarios of the turntable structure 10 .

The number of the first fixing holes 320 and the number of the second fixing holes may be flexibly adjusted according to actual use needs. Specifically in this embodiment, each first fixing hole 320 is evenly and spacedly arranged on the annular flange 310 around the axis of the annular flange 310.
