[0016] The application provides an automatic leveling device and a control system thereof, which has the following beneficial effects:

[0017] 1. The electronic leveler can detect the inclination angle of the top plate first when leveling the levelness of the top plate, and the detection data is read by the data reading unit in the controller, then the data is analyzed by the data calculation unit, and the distance required for each electric push rod to extend is calculated, and the electric push rod is controlled by the signal output unit to work, so that the horizontal angle of the top plate can be automatically adjusted, so that the top plate can be quickly and accurately leveled, the work efficiency is improved, the labor cost is reduced, it is suitable for various medical, scientific research, industrial and other scenes, and in the use process, the force and extension distance of the adjusting assembly can also be detected in real time through the pressure sensor and the infrared distance measuring sensor, so as to accurately control the extension amount of the electric push rod.

[0018] 2. When the ground has a certain slope, the ball head rod can rotate in the fixed sleeve, so that the bottom of the base is parallel to the ground, and the stability of the base is enhanced, and when the length of the electric push rod changes, the distance between the bases at the bottom of the two electric push rods will also change, so that sliding on the ground will occur, at this time, the ball can reduce the friction resistance when the base moves, so that it is easier to adjust the levelness of the top plate, and in the use process, the rubber column will also tightly contact the ball, so that only when the ball is subjected to excessive friction will it rotate, avoiding the condition that the bottom of the base directly slides when placed due to small friction, and the extension cover can also be used to shield the outside of the rotating assembly, avoid impurities from entering and affecting the normal work of the rotating assembly, and when the ball is damaged, the bottom cover can be separated from the base by unscrewing the bolts at the bottom of the bottom cover, so that the ball can be maintained and replaced.

[0019] 3. In the adjusting process, the controller also starts the electromagnet, since the magnetic pole at the bottom of the electromagnet is opposite to the magnetic pole at the upper end of the first permanent magnet, and the magnetic pole at the end close to the electromagnet of the second permanent magnet is the same as the magnetic pole of the electromagnet, at this time, since the magnetic force of the electromagnet is greater than that of the first permanent magnet, the repulsive force of the electromagnet to the second permanent magnet will offset the magnetic attraction of the first permanent magnet to the second permanent magnet, so that the driving plate will not move to the first permanent magnet, at this time, there is no downward pressure to drive the stabilizing sleeve, so that the base can slide with the ground, and after adjustment, when the power supply of the electromagnet is turned off, at this time, since there is no magnetic repulsion of the electromagnet, the first permanent magnet and the second permanent magnet will be attracted to each other, so that a larger pulling force can be provided to pull the driving plate, so that the stabilizing sleeve can be lowered by the guide groove and the slide rod, and the friction between the anti-skid pad and the ground is increased, so that the base can be prevented from sliding, and the subsequent placement is more stable.

[0020] 4、The application, when the electromagnet is started, the magnetic pole of the upper end of the electromagnet is the same with the magnetic pole of the lower part of the fourth permanent magnet, so repulsion occurs, and the repulsive force is greater than the attractive force between the third permanent magnet and the fourth permanent magnet, at this time the sliding frame will move up, so that the rubber pad and the anti-skid clamp block will not contact with the ball head rod, so that the rotation between the fixing sleeve and the ball head rod can occur, and after the power of the electromagnet is turned off, the third permanent magnet will attract the fourth permanent magnet, so that the sliding frame can be moved down by using the larger magnetic attraction force, the rubber pad is pressed on the top of the ball head rod, and at the same time, with the sliding frame moving down, the anti-skid clamp block is also pressed by the connecting rod, so that the anti-skid clamp block at four ends can clamp the ball head rod at the same time, the contact area is increased to improve the friction resistance, which is beneficial to enhance the stability of the device after leveling.

[0033] Please refer to Figures 4 to 7The inside of the base 503 is connected with an anti-skid assembly 6, which comprises a first permanent magnet 601, an electromagnet 602 and a driving plate 603. The first permanent magnet 601 is fixed in the center of the inside of the base 503, and the electromagnet 602 is arranged on the upper middle part of the base 503. The driving plate 603 is slidably connected to the outer upper end of the base 503. The anti-skid assembly 6 further comprises a second permanent magnet 604, a guide groove 605 and a sliding rod 606. The second permanent magnet 604 is fixed to one end of the driving plate 603. The guide groove 605 is formed in the other end of the driving plate 603, and the sliding rod 606 is slidably connected to the inside of the guide groove 605. The anti-skid assembly 6 further comprises a stabilizing sleeve 607, a limiting block 608 and an anti-skid pad 609. The stabilizing sleeve 607 is arranged at the end of the sliding rod 606, and the stabilizing sleeve 607 is slidably connected to the base 503. The limiting block 608 is fixed to the outer side of the base 503. The anti-skid pad 609 is arranged at the bottom of the stabilizing sleeve 607. The inside of the fixed sleeve 501 is arranged with a locking assembly 7, which comprises a third permanent magnet 701, a sliding frame 702 and a fourth permanent magnet 703. The third permanent magnet 701 is fixed to the inside of the upper end of the ball head rod 502. The sliding frame 702 is slidably connected to the inside of the fixed sleeve 501. The fourth permanent magnet 703 is arranged at the top center of the sliding frame 702, and the fourth permanent magnet 703 is attracted to the third permanent magnet 701. The locking assembly 7 further comprises a rubber pad 704, a connecting rod 705 and an anti-skid clamp block 706. The rubber pad 704 is fixed to the bottom of the sliding frame 702. The connecting rod 705 is rotatably connected to the outer end of the sliding frame 702. The anti-skid clamp block 706 is rotatably connected to the end of the connecting rod 705, and the anti-skid clamp block 706 is slidably connected to the fixed sleeve 501.

[0034] The specific operation is as follows: since the magnetic pole at the bottom of the electromagnet 602 is opposite to the magnetic pole at the upper end of the first permanent magnet 601, and the magnetic pole of the second permanent magnet 604 close to one end of the electromagnet 602 is the same as the magnetic pole of the electromagnet 602, at this time, since the magnetic force of the electromagnet 602 is greater than that of the first permanent magnet 601, the repulsion of the electromagnet 602 to the second permanent magnet 604 will offset the magnetic attraction of the first permanent magnet 601 to the second permanent magnet 604, so that the driving plate 603 will not move towards the first permanent magnet 601, at this time, there is no downward pressure to drive the stabilizing sleeve 607, so that the base 503 can slide on the ground. At the same time, since the magnetic pole at the upper end of the electromagnet 602 is the same as the magnetic pole at the lower end of the fourth permanent magnet 703, repulsion will occur, and the repulsive force is greater than the attractive force between the third permanent magnet 701 and the fourth permanent magnet 703. At this time, the sliding frame 702 will move upwards, so that the rubber pad 704 and the anti-skid clamping block 706 will not be in contact with the ball head rod 502, so that the fixed sleeve 501 and the ball head rod 502 can rotate, so that the bottom of the base 503 can be parallel to the ground, thereby enhancing the stability of the base 503. After automatic leveling, the controller 2 will turn off the electromagnet 602. At this time, since there is no magnetic repulsion of the electromagnet 602, the first permanent magnet 601 and the second permanent magnet 604 will be attracted to each other, thereby providing a larger pulling force to pull the driving plate 603. Therefore, the stabilizing sleeve 607 will be pushed downwards by the sliding rod 606 through the guide groove 605, and the friction between the stabilizing sleeve 607 and the ground will be increased through the anti-skid pad 609, thereby avoiding the sliding of the base 503, and making the subsequent placement more stable. At the same time, the third permanent magnet 701 will attract the fourth permanent magnet 703, so that the sliding frame 702 can be moved downwards by using the larger magnetic attraction, so that the rubber pad 704 is pressed tightly on the top of the ball head rod 502. At the same time, as the sliding frame 702 moves downwards, the anti-skid clamping block 706 will be squeezed by the connecting rod 705, so that the four anti-skid clamping blocks 706 can clamp the ball head rod 502 at the same time. By increasing the contact area, the frictional resistance is increased, which is beneficial to enhance the stability of the device after leveling.

[0035] Please refer to Figure 8 An automatic leveling control system applied to an automatic leveling device, a data processing module 8 is arranged in the controller 2, the data processing module 8 comprises a data reading unit 801, a data calculation unit 802 and a signal output unit 803, the data reading unit 801 is connected with the data calculation unit 802, and the data calculation unit 802 is connected with the signal output unit 803.

[0036] The specific operation is as follows: the data detected by the electronic level 3 will be read by the data reading unit 801 in the controller 2, then the data will be analyzed by the data calculation unit 802, and the distance required for each electric push rod 403 to extend and retract will be calculated, and then the electric push rod 403 will be controlled to work through the signal output unit 803.

[0037] In summary, the automatic leveling device and its control system, in use, first start the system, initialize the electronic level 3 and the electric push rod 403, and start the electromagnet 602. Since the magnetic poles at the bottom of the electromagnet 602 are opposite to the magnetic poles at the upper end of the first permanent magnet 601, and the magnetic poles close to one end of the second permanent magnet 604 are the same as the magnetic poles of the electromagnet 602, at this time, since the magnetic force of the electromagnet 602 is greater than the first permanent magnet 601, the repulsion of the electromagnet 602 to the second permanent magnet 604 will offset the magnetic attraction of the first permanent magnet 601 to the second permanent magnet 604, so that the driving plate 603 will not move towards the first permanent magnet 601. At the same time, since the magnetic poles at the upper end of the electromagnet 602 are the same as the magnetic poles at the lower part of the fourth permanent magnet 703, repulsion will occur, and the repulsion is greater than the attraction between the third permanent magnet 701 and the fourth permanent magnet 703. At this time, the sliding frame 702 will move upwards, so that the rubber pad 704 and the anti-skid clamping block 706 will not be in contact with the ball head rod 502, so that the rotation between the fixed sleeve 501 and the ball head rod 502 can occur. Then, the electronic level 3 will detect the inclination angle of the top plate 1, and the detection data will be read by the data reading unit 801 in the controller 2. Then, the data is analyzed by the data calculation unit 802, and the distance required for each electric push rod 403 to extend is calculated. Then, the signal output unit 803 controls the work of the electric push rod 403, and when the length of the electric push rod 403 changes, the distance between the two bases 503 at the bottom of the electric push rod 403 will also change, so that sliding on the ground will occur. At this time, the use of the ball 505 can reduce the frictional resistance when the base 503 moves, and the rubber column 506 will also closely adhere to the ball 505 during use, so that only the ball 505 will rotate when subjected to excessive friction. The outer side of the rotating assembly 5 can be shielded by the telescopic cover 508. Then, during the adjustment process, the force and the extension distance of the adjustment assembly 4 can be detected in real time by the pressure sensor 404 and the infrared distance measuring sensor 406. Finally, after automatic leveling, the controller 2 will turn off the electromagnet 602. At this time, since there is no magnetic repulsion of the electromagnet 602, the first permanent magnet 601 and the second permanent magnet 604 will be attracted to each other, so as to provide a larger pulling force to pull the driving plate 603. Therefore, the stable sleeve 607 will be pushed down by the sliding rod 606 through the guide groove 605, and the friction between the stable sleeve 607 and the ground will be increased by the anti-skid pad 609. At the same time, the third permanent magnet 701 will attract the fourth permanent magnet 703, so that the sliding frame 702 will be moved downwards by the larger magnetic attraction, and the rubber pad 704 will be pressed tightly on the top of the ball head rod 502. At the same time, as the sliding frame 702 moves downwards, the anti-skid clamping block 706 will be squeezed by the connecting rod 705, so that the four anti-skid clamping blocks 706 will clamp the ball head rod 502 at the same time, which is conducive to enhancing the stability of the device after leveling.
