[0025] Embodiment 1:

[0026] Combined with Figures 1 to 4 An automatic rotating dining table turntable comprises a chassis 1, a gear ring 2, a turntable 3, and a power mechanism 4. The gear ring 2 is rotatably mounted in the chassis 1, the turntable 3 is arranged above the gear ring 2, the power mechanism 4 is arranged in the chassis 1, and the power mechanism 4 is transmission-connected with the gear ring 2;

[0027] Ball bearings 5 ​​are arranged between the gear ring 2 and the rotating disk 3 and between the gear ring 2 and the chassis 1;

[0028] It also includes a control mechanism, which includes a Hall switch 7. Two Hall switches 7 are arranged front and back below the turntable. A spherical magnet 8 that rolls back and forth is arranged between the two Hall switches 7. An iron sheet 6 that cooperates with the spherical magnet 8 is arranged below the turntable 3. The iron sheets 6 are arranged in a ring array around the outer ring of the turntable. The iron sheets 6 move with the rotation of the turntable 3.

[0029] During the specific implementation, the turntable is manually pushed to rotate, and the turntable rotates through the ball bearings between the turntable and the gear ring, and the iron sheet set below the outer ring of the turntable moves with the rotation of the turntable. When the iron sheet moves to the left, the spherical magnet set below moves to the front side under the action of magnetic attraction, and the movement of the front side of the spherical magnet causes the magnetic field to change. The Hall switch on the front side senses the change in the magnetic field and starts to control the power mechanism to rotate forward; when the iron sheet moves to the right, the spherical magnet set below moves to the rear side under the action of magnetic attraction, and the movement of the rear side of the spherical magnet causes the magnetic field to change. The Hall switch on the rear side senses the change in the magnetic field and starts to control the power mechanism to reverse, thereby achieving the technical effect of forward and reverse rotation of the turntable.

[0030] When using it, when your hand feels the turntable has the power of self-rotation, you can release the turntable and the turntable will rotate by itself.

[0031] In a preferred implementation of this embodiment, the power mechanism 4 includes a drive motor 401, a transmission 402, and a drive gear 403. The output end of the drive motor 401 is connected to the drive gear 403 through the transmission 402, and the drive gear 403 is meshed with the gear ring 2 through the outer teeth of the outer ring. The drive motor 401 is provided with a motor drive module electrically connected thereto, and the two Hall switches 7 are electrically connected to the motor drive modules respectively.

[0032] When in use, the two Hall switches are activated and deactivated respectively, and are electrically connected to the motor drive module to control the forward and reverse rotation of the drive motor. The drive motor is connected to the drive gear through the transmission, thereby driving the gear ring to rotate.

[0033] In a preferred implementation manner of this embodiment, the outer ring of the turntable 3 is also provided with a speaker 10, a microphone 11, and a microprocessor 12, the speaker 10, the microphone 11 are electrically connected to the signal input end of the microprocessor 12, and the signal output end of the microprocessor 12 is electrically connected to the motor drive module.

[0034] In the specific implementation, the speaker and microphone are both arranged on the outer ring of the turntable. The microphone converts the received sound wave signal into an electrical signal and sends it to the microprocessor through the signal line. The microprocessor sends a signal to the motor drive module or to the speaker according to the signal received from the microphone. After receiving the signal, the speaker converts the electrical signal into a sound wave signal and plays it out; after receiving the signal, the motor drive module starts the motor to rotate clockwise / counterclockwise. The rotation mode can be uniformly set according to hobbies or needs.

[0035] A Bluetooth wireless module can be set in the microprocessor, and it can be wirelessly connected to external mobile devices (such as intercoms on the bar counter, mobile phones, etc.) through the Bluetooth wireless module. Through the settings of speakers, microphones and microprocessors, the forward, reverse and stop of the turntable can be controlled by voice, and the Bluetooth wireless module can also be used to achieve the effect of Bluetooth audio voice playback, which is more intelligent and humane.

[0036] A preferred implementation manner of this embodiment further includes a power cord, one end of which is electrically connected to the motor drive module, and the other end of which is provided with a charging connector, and the charging connector is connected to the power bank, i.e., the power module.

[0037] When in use, the direction in which the turntable rotates is the same as the direction in which it is manually pushed, so that the spherical magnet always remains close to one of the Hall switches, driving the Hall switch to remain connected, and the other one always remains closed.

[0038] When the turntable itself is rotating, if you want to rotate in the opposite direction, you can manually push the turntable to reverse. The balls set on the upper and lower sides of the gear ring can push the turntable to flip relative to the gear ring and keep it stationary relative to the chassis for a short time. At this time, the spherical magnet rolls and resets to the middle, both Hall switches are closed, the drive motor has no power, and the turntable stops rotating.

[0039] If you feel that the turntable has no power and continues to rotate in the opposite direction, the spherical magnet set under the outer ring of the turntable will roll in the opposite direction, causing the magnetic field to change in the opposite direction. The other of the two Hall switches under the turntable is connected, and the drive motor is reversed through the motor drive module. The drive motor drives the screw drive gear to reverse, and the reverse rotation of the drive gear drives the gear ring to rotate in the opposite direction. The gear ring rotates through the balls set up above and below, and then drives the turntable above to rotate in the opposite direction. The automatic rotation of the turntable is realized.

[0040] When the present invention is implemented, it is connected to an external power bank or other power storage device to supply power to the driving motor.

[0041] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
