DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-3 As shown, a circumferential rotation drive mechanism for a movable seat comprises a rotating base 1 located at the bottom of the movable seat, an upper seat body 2 is rotatably mounted on the upper end of the rotating base 1 for driving other parts of the seat to rotate circumferentially, a rotating drive assembly 3 is mounted between the rotating base 1 and the upper seat body 2 to provide a driving torque for the upper seat body 2; during the rotation of the upper seat body 2, it is easy to tilt and deviate, so a rotating support assembly 4 is arranged between the rotating base 1 and the upper seat body 2 and is circumferentially distributed relative to the rotating connection thereof, the rotating support assembly 4 is usually arranged in a centrally symmetrical manner, an electric slip ring assembly 5 is arranged at the rotating connection between the rotating base 1 and the upper seat body 2 to meet the electrical conductivity and signal transmission requirements of the movable assembly, and the electric slip ring assembly 5 does not affect its mobility during the rotation of the upper seat body 2.

[0023] Specifically, a rotating opening 6 is provided at the center of the upper end of the rotating base 1 for assembling the corresponding connection structure. A circular fixed base 61 is fixed inside the rotating opening 6 to cover the edge of the rotating opening 6. The fixed base 61 is fixed circumferentially by a screw. A rotating base 62 is rotatably connected to the inner side of the fixed base 61 through a rotating bearing. The upper end of the rotating base 62 is connected to the upper base body 2 through an adapter tube 63 and rotates synchronously. The lower end of the rotating base 62 is connected to the electric slip ring assembly 5 through an adapter plate 64. The outer circumferential side of the rotating base 62 is meshed with the rotating drive assembly 3 for transmission. The power transmission cable connected to the electric slip ring assembly 5 passes through the adapter tube 63 and extends upward.

[0024] Specifically, the rotating drive assembly 3 includes a driving gear ring 31 fixed to the outer circumferential side of the rotating base 62, and a driving gear 32 meshing with the driving gear ring 31 is rotatably installed inside the rotating base 1, and the driving gear 32 is connected to the driving motor 34 through the speed change gear set 33. The driving motor 34 provides a driving torque, and the speed change gear set 33 is encapsulated in a corresponding gearbox body for speed change transmission, thereby driving the driving gear 32 and the driving gear ring 31 to mesh and transmit.

[0025] Further, similar to the conventional electric slip ring structure, the electric slip ring assembly 5 in the present application includes a slip ring body 51 fixedly installed in the rotating base 1, the slip ring body 51 has a conductive ring 52 and a brush 53 in contact with the conductive ring 52, and the brush 53 is fixedly connected to the adapter plate 64. When the adapter plate 64, the rotating base 62 and the adapter tube 63 rotate synchronously, the brush 53 also rotates relative to the conductive ring 52 and maintains its power transmission or signal transmission.

[0026] Furthermore, the rotating support assembly 4 includes a plurality of support seats 41 mounted on the upper end of the rotating base 1, and the support seats 41 are usually arranged in a central symmetric manner. The support seat 41 has a support opening 42 opposite to the bottom of the upper seat body 2, and a support roller 43 is rotatably mounted in the support opening 42 and is pressed against the bottom of the upper seat body 2, and the central axis of the support roller 43 is opposite to the central axis of the rotating base 1 and the rotating connection of the upper seat body 2. When the upper seat body 2 rotates circumferentially, the support roller 43 rolls accordingly, and the number of the support seats 41 is not less than 3.

[0027] In addition, there is enough assembly cavity inside the rotating base 1, and the rotating base 1 specifically includes an upper top plate 11 and a lower bottom plate 12 which are opposite to each other. An outer plate 13 which closes the upper top plate 11 and the lower bottom plate 12 is connected between the upper top plate 11 and the lower bottom plate 12, and a corresponding wiring port is also opened on the side of the outer plate 13. The upper top plate 11 and the outer plate 13 are plugged and fixed to each other at the intersection.

[0028] At the same time, in order to ensure that the rotating drive assembly 3 and the electric slip ring assembly 5 can be assembled normally, the rotating base 1 is vertically provided with a mounting plate 14, the upper end of the mounting plate 14 is connected to the upper top plate 11 through the mounting top plate 15 and a threaded member is provided therebetween, and the lower end of the mounting plate 14 is connected to the lower bottom plate 12 through the mounting bottom plate 16 and a threaded member is provided therebetween. The mounting plate 14 is rectangular and is connected and fixed one by one at the head and tail, and the intersection is plugged and spliced.

[0029] It can be seen that a first support frame 17 for installing a circuit board is connected between the mounting uprights 14, and both ends of the support frame 17 have support plates that are vertically arranged and fit and fixed to the mounting uprights 14; the upper top plate 11 is connected to a second support frame 18 for installing the rotation drive assembly 3, and the second support frame 18 is composed of a plurality of plates, which are fitted to the lower end of the upper top plate 11 and kept isolated from the lower bottom plate 12; the second support frame 18 is connected to a third support frame 19 for installing the electric slip ring assembly 5, and the third support frame 19 is connected and fixed to the bottom of the electric slip ring assembly 5, and the third support frame 19 has two independent plates whose relative positions can be adjusted up and down, thereby adjusting the height of the electric slip ring assembly 5 to ensure its assembly accuracy.

[0030] Obviously, in order to facilitate internal wiring, a hollow opening is opened on the mounting plate 14 for the cable to pass through, and the mounting top plate 15 and the mounting bottom plate 16 are a frame structure, which maintains the structural strength of the rotating base 1 without affecting the normal transmission of the upper end rotating drive assembly 3.

[0031] Preferably, the rotating base 1 is in a box-shaped structure as a whole, and outwardly extending support feet 7 are fixed to the corners of the lower end thereof, and reinforcing ribs are provided at the junction of the support feet 7 and the rotating base 1 . Multiple groups of support feet 7 ensure the stability of the bottom of the rotating base 1 .

[0032] In summary, the principle of this embodiment is that the rotating drive assembly 3 drives the upper seat body 2 to rotate circumferentially relative to the rotating base 1, and the rotating support assembly 4 therebetween maintains the horizontal balance of the upper seat body 2, wherein the electric slip ring assembly 5 meets the requirements of up and down power transmission and signal transmission during the rotation process, and the rotating support assembly 4 can effectively prevent the electric slip ring assembly 5 from deflecting, thereby ensuring the stability of its power transmission and signal transmission.
