Example one

As shown in fig. 1 to 10, the intelligent dining table provided by the present embodiment includes a rotating table top support 1, a rotating mechanism 2, a table top rotation angle measuring mechanism 3, and a clutch mechanism 4 for separating the rotating table top support 1 from the rotating mechanism 2 in a transmission manner.

The center of the bottom surface of the rotating desktop support 1 is fixedly connected with the clutch mechanism 4 through a sleeve shaft 5, and the clutch mechanism 4 is fixed on the rotating end of the rotating mechanism 2.

The desktop rotation angle measuring mechanism 3 comprises a magnet 301, a magnetic-sensing angle sensor 302 and a controller 303, wherein the magnet 301 is fixed on the clutch mechanism 4 and rotates along with the clutch mechanism 4, and the magnetic-sensing angle sensor 302 is located under the magnet 301 and keeps still.

The magnetic sensing angle sensor 302 is communicatively connected with an input end of the controller 303, and an output end of the controller 303 is communicatively connected with a controlled end of the rotating mechanism 2.

As shown in fig. 1 to 10, the intelligent dining table will be described in detail as follows:

in this embodiment, the rotating mechanism 2 is used as a power source of the rotating dining table, that is, the rotating mechanism 2 drives the rotating table top support 1 to rotate, and the rotating table top support 1 is fixed with a table top for placing dishes, specifically, the table top may be made of transparent glass.

In this embodiment, the rotation of the rotatable table top support 1 is the rotation of the table top.

Meanwhile, in the embodiment, the rotating mechanism 2 does not directly drive the rotating tabletop support 1, and the clutch mechanism 4 is used as a power transmission mechanism to indirectly drive the sleeve shaft 5 to rotate, and the sleeve shaft 5 is fixedly connected with the center of the rotating tabletop support 1, so that the rotating tabletop support 1 can rotate. In this embodiment, the clutch mechanism 4 is used to realize the transmission separation between the rotating table top support 1 and the rotating mechanism 2, on one hand, the force required for the person to stir the rotating table top support 1 can be reduced, and on the other hand, the motor 13 in the rotating mechanism 2 can be prevented from being locked when the person stirs the rotating table top support 1, so that the motor 13 is damaged.

Please refer to embodiment two for the specific structure of the clutch mechanism 4.

The mechanism 3 for measuring the rotation angle of the rotary table top support 1 is the table top angle measuring mechanism 3, as shown in fig. 5:

first, it has been explained above that the clutch mechanism 4 is fixed on the rotating end of the rotating mechanism 2, and the clutch mechanism is also fixedly connected with the rotating table top support 1 through the sleeve shaft 5, so that the clutch mechanism 4 rotates along with the rotating table top support, and further the magnet 301 rotates along with the rotating table top support 1.

And magnet 301 is provided with magnetism sensing angle sensor 302 under, and through the above-mentioned design, magnet 301 will pass through magnetism sensing angle sensor 302 every rotation round, and then makes magnetism sensing angle sensor 302 detect the magnetic field change to convert the signal of telecommunication into, transmit to controller 303, the controller can carry out the change of angle according to the signal of telecommunication that spreads into, finally realizes the measurement of 1 turned angle is supported to the revolving table top.

In the present embodiment, the perpendicular distance between the magnet 301 and the magnetic sensor 302 is defined to be 2mm, which can increase the detection accuracy.

The determination of the data transmitted from the magnetic angle sensor 302 in the controller 303 of the present invention specifically includes the following steps:

first, since the controller 303 is in communication connection with the magnetic angle sensor 302, the controller 303 reads the data transmitted from the magnetic angle sensor 302 and converts the data into binary data, and then performs step S101.

S101, defining variables a, b, c and d, and respectively assigning initial values to be 0.

In this step, in order to ensure the accuracy of the judgment of the controller 303, three variables are set as assignment objects of the three-time data transmitted by the magnetic angle sensor 302, so that data subtraction is facilitated, a subtraction result is assigned to d, and the size of d and a preset value is further judged, so that the controller 303 controls the rotating mechanism 2 to perform different operations according to the judgment result.

The following is a specific judgment process of the controller 303, that is, a specific working method of the intelligent dining table:

and S103, assigning the value of the first data to a variable a by the controller, and receiving second data transmitted by the magnetic-sensing angle sensor after preset time.

And S104, judging whether the second data is valid or not by the controller, if so, assigning the value of the variable a to the variable b, assigning the value of the second data to the variable a, receiving third data transmitted by the magnetic-sensitive angle sensor after preset time, and executing the step S105, otherwise, executing the step S102 again.

S105, judging whether the third data is valid or not by the controller, if so, assigning the value of the variable b to the variable c, assigning the value of the variable a to the variable b, assigning the value of the third data to the variable a, finally subtracting the variable a from the variable c, and assigning the obtained result to the variable d; otherwise, step S102 is re-executed.

Step S102 to step S105 are processes of assigning values to the cubic data transmitted by the magnetic angle sensor 302, and the reason for this is as follows: the difference value between the third data and the first data can be calculated conveniently, and the automatic control of the rotating mechanism 2 can be realized by judging the difference value and the preset value. And the judgment accuracy can be improved by adopting the data of three times and using the difference value for judgment.

In this embodiment, the reason why the validity of each incoming data needs to be determined is as follows: the misjudgment is prevented, and the judgment standard of the effectiveness is as follows: and judging whether the upper eight bits and the lower eight bits of the incoming data accord with the output data code reversal, if so, determining valid data, and otherwise, determining the data as invalid data.

In the present embodiment, the predetermined time for the magnetic angle sensor to perform data transmission is 10ms to 130ms, specifically 100ms in the present embodiment.

As can be seen from the above, what the controller 303 finally determines from the preset value is the variable d, and after the variable d reads the data for three times, the actual value is the difference between the data for the third time and the data for the first time, so that the step S106 is the criterion for determining, that is, when the value of the variable d is in what range, what operation the controller 303 correspondingly controls the rotating mechanism 2 to perform is referred to as step S106.

The rotary table top support 1 can be used for the following situations:

when the rotating table top support 1 is stationary, the value of the variable d is theoretically 0, and in practice, the rotating table top support 1 vibrates or shakes a little, and the value of the variable d may be non-0, so that the controller 303 considers the value of the variable d to be stationary within a certain range. In the present embodiment, the setting is between-20 and 20, and the controller does not output the signal that the motor 13 is to rotate.

When the rotating desktop support 1 is still or reversely rotated, if a person manually pulls the rotating desktop support 1 forward, the value of the variable d will change, for example, the variable d is 60, and similarly, a range is also needed to achieve accurate control, in this embodiment, the value of the variable d is set to be between 30 and 1000, or between-65506 and-64535, at this time, the controller first checks the state of the reverse rotation signal, if the reverse rotation signal is true, the reverse rotation signal is turned off, and a time period is waited, which needs to refer to the data given by the motor manufacturer (determined according to the actual power of the motor 13, and the detected information is true and false, which is the prior art), so as to ensure the safety of the motor, and then the forward rotation signal is output. If the reverse rotation signal is false, the forward rotation signal is directly output, the suction of the forward rotation relay is controlled through the triode auxiliary circuit, and the desktop rotates forwards.

Referring to fig. 8 and 7, the input terminals sec1 and sec2 of fig. 8 are connected to the same pin of the controller 303 of fig. 7, and control the conduction of the transistor Q2 or Q3 through the electric signal output by the controller 303, so as to close the relay K1 or K2, thereby implementing the forward and reverse rotation of the motor 13.

The value of the positive variable d is negative when the angle chip is 360-0 degrees. Therefore, data of-65536 is used, and therefore, two judgment conditions are required to satisfy one of the conditions.

Similarly, when the rotating desktop support 1 is still or rotates in the forward direction, if a person pulls the rotating desktop support 1 in the reverse direction, the value of the variable d may also change, for example, the variable d is-60, in this embodiment, the value of the variable d is set to be between-1000 to-30 or 64535 to 65506, and similarly, the controller 303 first checks the state of the forward rotation signal, if the forward rotation signal is true, turns off the forward rotation signal, waits for a period of time (the same as the above forward rotation signal, and the controller 303 detects that the signal is the prior art), which is referred to the motor manufacturer to give data, ensures the safety of the motor 13, and then outputs the reverse rotation signal, if the reverse rotation signal is false, directly outputs the forward rotation signal, and controls the reverse rotation relay to be attracted through the triode auxiliary circuit, so that the rotating desktop support 1 rotates in the reverse direction. The circuit is also shown in fig. 7 and 8, and the principle is already explained in the above forward rotation, which is not repeated herein.

Since the angle chip is in the range of 0 ° to 360 °, the value of the inverted variable d is positive. Therefore, 65536 data is used, and therefore, two judgment conditions are required, and one of the conditions is satisfied.

In addition, when the variable d is between-30 and-20 or between 20 and 30, the controller 303 outputs a signal to keep the current working state of the rotating mechanism 2 unchanged.

In this embodiment, the controller 303 is a single chip, i.e. the IC1 in fig. 7, and the IC2 in fig. 7 is a magnetic angle sensor, which are all conventional electronic devices.

In the present embodiment, the motor 13 in the rotating mechanism 2 may also be an ac motor, and a control circuit diagram thereof is shown in fig. 9.

Example two

As shown in fig. 1 to 10, this embodiment is a specific implementation of the intelligent dining table in the first embodiment, that is, a detailed result diagram of each mechanism is provided.

First, as shown in fig. 3, the present embodiment gives a specific mechanism diagram of the clutch mechanism 4.

Preferably, the clutch mechanism 4 includes a mounting plate 401, a plurality of clutch friction posts 402 and a plurality of adjusting studs 403.

The clutch friction columns 402 are fixed on the rotating end of the rotating mechanism 2, the number of the clutch friction columns 402 is consistent with that of the adjusting studs 403, the clutch friction columns 402 correspond to the adjusting studs 403 in position one by one, and the adjusting studs 403 contact the top surfaces of the clutch friction columns 402 in corresponding positions after threads penetrate through the mounting disc 401.

In this embodiment, the clutch friction column 402 is fixed on the rotating end of the rotating mechanism 2, the adjusting stud 403 is threaded through the mounting plate 401 and contacts the clutch friction column 402 at the corresponding position, and the end of the sleeve shaft 5 away from the rotating table top support 1 is fixed in the center of the mounting plate 401.

Through the design, the rotating mechanism 2 drives the clutch friction column 402 to rotate, then the friction between the clutch friction column 402 and the corresponding position adjusting stud 403 is utilized to drive the mounting disc 401 to rotate, further the sleeve shaft 5 is driven to rotate, and finally the rotation of the rotating desktop support 1 is realized.

The design realizes the transmission separation of the rotating mechanism 2 and the rotating desktop support 1, on one hand, the force required for the rotating desktop support 1 to be stirred by a hand can be reduced, and on the other hand, the motor 13 in the rotating mechanism 2 is prevented from being locked when the rotating desktop support 1 is stirred by the hand, so that the motor 13 is damaged.

The scheme is further optimized as follows:

preferably, a spring 404 is further arranged between the adjusting stud 403 and the clutch friction column 402 at the corresponding position, wherein two ends of the spring 404 are respectively and fixedly connected with the adjusting stud 403 and the clutch friction column 402.

Through the design, the adjustment of the clutch force between the motor 13 and the rotary table top support 1 is realized by adjusting the length of the adjusting stud 403 and further adjusting the elasticity of the spring 404.

In practical use, the rotary table top support 1 rotates too slowly (generally rotates 1 degree in one second), the machine rotates to shake (the theoretical rotating state is difficult to achieve during product production), external factors such as environmental magnetic field interference exist, the accuracy of data detected by the magnetic-sensitive angle sensor is not enough, and in order to solve the problem, two gears with a certain gear ratio are arranged between the magnet 301 and the mounting disc 401, and the large gear drives the small gear to rotate so as to improve the rotating speed of the magnet 301. Typically 5 to 15 times the tooth ratio.
