[0031] In practical application, rotary dining table includes dining table main body 6 and dining table carousel 7, dining table carousel 7 rotation is arranged on dining table main body 6, driving part 5 and dining table carousel 7 transmission connection, driving part 5 is motor in this embodiment, and dining table carousel 7 transmission connection mode of motor adopts the transmission connection mode in prior art.The rotating component 3 rotates around the radial of dining table carousel 7, by the setting of elastic component 1, dining table carousel 7 is abutted to the surface close to dining table main body 6 by rotating component 3, due to the elastic force of elastic component 1, friction between rotating component 3 and dining table carousel 7, dining table carousel 7 rotation drives rotating component 3 to roll, rotating component 3 rolls and drives encoder 4 to rotate, and the phase difference of encoder 4 is read by encoder 4 detection circuit, and the phase difference is sent to main control circuit 84, and main control circuit 84 controls the direction of motor according to the phase difference, speed, stop action, realizes the forward rotation of dining table carousel 7, reverse rotation, stop, can also realize the controllable speed regulation of fast and slow 2 gears, realizes the control to rotary dining table.In this embodiment, elastic component 1 is installed on dining table main body 6, after driving part 5 control circuit and driving part 5 are electrically connected, without making big change to the transmission device of original rotary dining table, it is convenient to improve on the basis of original rotary dining table, realize the control to rotating speed and direction.

[0032] Further, as shown in Figure 2 The elastic component 1 includes: the elastic component 1 includes: fixed column 11, elastic part 12 and limit block 13;The bottom of fixed column 11 is arranged on dining table main body 6, the elastic part 12 is sleeved on fixed column 11, the connecting component 2 is sleeved on fixed column 11, the elastic part 12 and connecting component 2 abut, and the limit block 13 is arranged on the top end of fixed column 11.

[0033] In practical applications, the elastic element 12 is a spring, which is sleeved on the fixed post 11. In other embodiments, the elastic element 12 can be made of rubber. One end of the elastic element 12 abuts against the main body 6 of the dining table, and the other end of the elastic element 12 abuts against the connecting component 2, thereby supporting the connecting component 2 and making the rotating component 3 and the dining table turntable 7 close together. By setting the fixed post 11, after the elastic element 12 is sleeved on the fixed post 11, it can prevent the elastic element 12 from tilting.

[0034] Furthermore, such as Figure 3 As shown, the connecting assembly 2 includes: a connecting plate 21, a first support plate 22, and a second support plate 23; the connecting plate 21 has a sliding hole, and the connecting plate 21 is sleeved on the fixed post 11 through the sliding hole; the elastic element 12 abuts against the connecting plate 21; the diameter of the limiting block 13 near the fixed post 11 is larger than the diameter of the sliding hole; the first support plate 22 and the second support plate 23 are disposed on the connecting plate 21; and the rotating assembly 3 is rotatably disposed on the first support plate 22 and the second support plate 23.

[0035] In practical applications, the first support plate 22 and the second support plate 23 are parallel to each other. The setting of the fixing post 11 limits the sliding direction of the connecting plate 21, allowing the connecting plate 21 to slide along the length direction of the fixing post 11. This prevents the connecting component 2 from tilting too much when the user rotates the dining table turntable 7, thereby preventing the first support plate 22 or the second support plate 23 from abutting against the dining table turntable 7 and ensuring the contact between the rotating component 3 and the dining table turntable 7. The setting of the limiting block 13 can prevent the connecting plate 21 from disengaging from the fixing post 11, improving the connection stability.

[0036] Furthermore, such as Figure 2 and Figure 3 As shown, the rotating assembly 3 includes a roller 31 and a wheel axle 32. The wheel axle 32 is rotatably mounted on the first support plate 22 and the second support plate 23. The wheel axle 32 is arranged radially along the turntable 7. The roller 31 is mounted on the wheel axle 32. The roller 31 abuts against the turntable 7. The wheel axle 32 is fixedly connected to the code disk shaft 41 of the encoder 4.

[0037] In practical applications, the roller 31 and the turntable 7 abut against the surface of the main body 6 of the dining table. Rotating the turntable 7 causes the roller 31 to roll, which in turn drives the axle 32 to rotate. The axle 32 then drives the code disk shaft 41 to rotate, which in turn drives the code disk 42 to rotate, thus achieving a phase change in the encoder 4 to form a phase difference. The first support plate 22 and the second support plate 23 provide stable support for the rotating assembly 3.

[0038] Furthermore, such as Figure 3As shown, the control assembly 8 comprises a first control board 81, a second control board 82 and a connector SW1; the first control board 81 is arranged on the dining table body 6, the second control board 82 is arranged on the connecting plate 21, the shell 43 of the encoder 4 is arranged on the second control board 82, the encoder 4 detection circuit, the main control circuit 84 and the drive 5 control circuit are all arranged on the first control board 81, one end of the connector SW1 is arranged on the first control board 81, the other end of the connector SW1 is arranged on the second control board 82, the encoder 4 is electrically connected with the other end of the connector SW1, and the encoder 4 detection circuit is electrically connected with one end of the connector SW1.

[0039] In actual application, the first control board 81 and the second control board 82 are both PCB boards, the first control board 81 and the second control board 82 are electrically connected through the connector SW1, so that the connection between the first control board 81 and the second control board 82 becomes simple and easy to implement, without the need for complex welding or other fixed connection methods. Moreover, the connector SW1 has a specific pin arrangement and interface shape, which facilitates the connection of wires to the first control board 81 and the second control board 82 according to certain rules, avoiding the problem of wiring disorder.

[0040] Further, as shown in the figure, Figure 4 the encoder 4 detection circuit comprises a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4 and a first capacitor C1; a first end of the first resistor R1 is connected with the A-phase output end of the encoder 4 as a first input end of the encoder 4 detection circuit, the first end of the first resistor R1 is connected with the first voltage end through the second resistor R2, a second end of the first resistor R1 is connected with the main control circuit 84 as a first output end of the encoder 4 detection circuit, a first end of the third resistor R3 is connected with the B-phase output end of the encoder 4 as a second input end of the encoder 4 detection circuit, the first end of the third resistor R3 is connected with the first voltage end through the fourth resistor R4, a second end of the third resistor R3 is connected with the main control circuit 84 as a second output end of the encoder 4 detection circuit, a third input end of the encoder 4 detection circuit is connected with the C-phase output end of the encoder 4, and the third input end of the encoder 4 detection circuit is connected with the ground end.

[0041] In practical application, the A-phase output end and the B-phase output end of the encoder 4 are signal ends, and the C-phase output end is a common end. By reading the state of the B-phase when the state of the A-phase of the encoder 4 changes, the rotating direction of the dining table turntable 7 can be determined, and the rotating direction of the dining table can be identified. When there is no level change in the A-phase output end and the B-phase output end of the encoder 4 received within a preset time, it is determined that the user has paused the turntable, and the main control circuit 84 controls the motor to stop outputting through the driving element 5 control circuit. By reading the state of the B-phase when the state of the A-phase of the encoder 4 changes, the rotating direction of the dining table can be determined, and the rotating direction of the dining table can be identified. When the dining table rotates clockwise, multiple counterclockwise signals are identified, which can be determined as the user rotating the dining table in the opposite direction. At this time, the main control circuit 84 will adjust the control port of the motor through the driving element 5 control circuit to switch the rotating direction of the motor, realizing seamless switching of the rotating direction of the user. By comparing the level state change time of the A-phase with the reference voltage of the current gear, it can be determined whether the dining table turntable 7 rotates too fast or too slow, and then the main control circuit 84 adjusts the rotating speed of the motor through the driving element 5 control circuit to realize uniform rotation of the dining table at the set gear. During use, if the user needs to switch from slow gear to fast gear, the user can accelerate the dining table turntable 7 in the direction of the current rotation of the dining table turntable 7. If the main control circuit 84 detects that the running direction does not change and the state of the A-phase changes continuously at multiple points, the fast gear mode will be switched. During use, if the user needs to switch from fast gear to slow gear, the user can keep the dining table still for a certain period of time. If the main control circuit 84 identifies that the A-phase of the encoder 4 does not trigger within that time, that is, there is no level change, the slow gear mode will be switched.

[0042] Further, as shown in Figure 4 The main control circuit 84 includes a main control chip U1, a voltage stabilizing chip U2, and a power switch SW2. The input end of the voltage stabilizing chip U2 is connected to the power supply end through the power switch SW2, and the output end of the voltage stabilizing chip U2 is connected to the main control chip U1. The encoder 4 detection circuit and the driving element 5 control circuit are connected to the main control chip U1.

[0043] In practical application, the main control chip U1 is a single-chip microcomputer, and the voltage stabilizing chip U2 is used to reduce the USB power supply 5V voltage to 3.3V to ensure stable operation of the single-chip microcomputer. The first output end and the second output end of the encoder 4 detection circuit are respectively connected to different I / O ports of the single-chip microcomputer. After the single-chip microcomputer detects the level change of the first output end and the second output end of the encoder 4 detection circuit, that is, detects the phase change of the A-phase and the B-phase of the encoder 4, the driving element 5 control circuit outputs corresponding signals according to the change to control the rotating direction, speed, and stopping action of the motor. Through the setting of the power switch SW2, the power switch SW2 can be turned off under the condition that the rotating dining table is not used for a long time, thereby saving energy, prolonging the service life of the equipment, and reducing safety risks.

[0044] Further, as shown in Figure 4 The driving member 5 control circuit includes a driving chip U3, the input end of the driving chip U3 is connected with the master control chip U1, and the output end of the driving chip U3 is connected with the driving member 5.

[0045] In actual application, the driving chip U3 can adopt a motor driving chip U3 in the prior art, which is an integrated circuit specially used for controlling the operation of a motor. The motor needs a large current and power to drive when running, and the current and power provided by the single-chip microcomputer are usually small. The single-chip microcomputer sends corresponding control signals according to the received phase difference, and the power of the control signals sent by the single-chip microcomputer can be amplified through the motor driving chip U3 to meet the energy requirement of the motor running, so that the motor can generate sufficient torque and rotating speed, and various control functions of the motor can be realized, such as forward and reverse rotation control, speed control, stop control, etc.

[0046] Further, as shown in Figure 4 The control assembly 8 is further provided with a warning circuit 86, the warning circuit 86 includes a buzzer BU, a fifth resistor R5, a first diode D1 and a first triode Q1, the base of the first triode Q1 is connected with the master control circuit 84 through the fifth resistor R5, the emitter of the first triode Q1 is connected with the ground, the collector of the first triode Q1 is connected with the second voltage end through the buzzer BU, the anode of the first diode D1 is connected with the collector of the first triode Q1, and the cathode of the first diode D1 is connected with the second voltage end.

[0047] In actual application, the first triode Q1 plays a role of switch. When the first triode Q1 is in the cut-off state, the collector and the emitter thereof are equivalent to open circuit, the circuit is not connected, and the buzzer BU does not sound. When the first triode Q1 is in the saturation state, the collector and the emitter thereof are equivalent to short circuit, the circuit is connected, and the buzzer BU sounds. The first diode D1 is a voltage stabilizing diode, which plays a role of voltage stabilization. Under the condition that the circuit of the first triode Q1 is connected, the voltage stabilizing diode is reversely biased, the voltage stabilization of the buzzer BU is realized, and the normal work of the buzzer BU is ensured. The base of the first triode Q1 is connected with the I / O port of the single-chip microcomputer. The cut-off or conduction state of the first triode Q1 is controlled by controlling the level change of the I / O port, so that the control of the buzzer BU is realized, such as the start-up prompt and the gear switching prompt through the buzzer BU. Specifically, if the sensor triggers the wake-up after entering the sleep state, the buzzer BU will sound for one time to prompt the wake-up, the start-up prompt is realized, the buzzer BU will sound for one time when the dining table turntable 7 is switched from the fast gear to the slow gear, and the buzzer BU will sound for two times to prompt when the dining table turntable 7 is switched from the slow gear to the fast gear.

[0048] Further, as shown inFigure 4 As shown, the control component 8 is further provided with an indication circuit 87, which comprises a light-emitting diode (LED) and a sixth resistor R6, an anode of the light-emitting diode is connected to the master chip U1 through the sixth resistor R6, and a cathode of the light-emitting diode is connected to a ground terminal.

[0049] In actual application, the running state of the light-emitting diode LED can indicate the state of the indication circuit 87, for example, the light-emitting diode LED is always on after the circuit is powered on, so as to determine whether the circuit is powered on successfully, and the circuit state can be detected.

[0050] When the drawings are referred to for explanation, the new features appearing are described; in order to avoid the description being not concise due to repeated reference to the drawings, the features already described are not referred to the drawings again under the condition of clear expression.
