As shown in fig. 1 to 6, the intelligent lifting learning table according to the technical scheme of the invention comprises a table top 10, wherein the table top 10 comprises a middle table top 1 and end table tops 3 respectively arranged at two ends of the middle table top 1, and a first lifting device for realizing lifting and inclining of the middle table top 1 is arranged at the bottom of the middle table top 1. The bottoms of the table tops 3 at the two end parts are provided with second lifting devices for realizing the lifting and the inclination of the table top 10. The front lifting mechanism 11 and the rear lifting mechanism 21 of the first lifting device work simultaneously, and the lifting of the middle table top 1 can be realized; the rear lifting mechanism 21 works alone to realize the inclination of the middle table top 1. The second lifting device realizes the lifting of the whole table top 10, and the tilting cylinder 34 in the second lifting device realizes the tilting of the whole table top 10. The inclination refers to that according to the human engineering, when the desk is used, the desk is generally inclined towards the standing or sitting side, the local independent lifting and inclination control of the middle table top 1 can be realized, the operation is flexible, the adaptability is strong, the lifting and inclination of the whole table top can be realized, and the intelligent lifting learning desk is suitable for users of different ages.

The push rods of the left air cylinder 111 and the right air cylinder 112 are rotatably connected with the bottom of the middle table board 1, and the air cylinder bodies of the left air cylinder 111 and the right air cylinder 112 are respectively inclined towards the bottom of the end table board 3 and rotatably connected with the bottom surface of the end table board 3.

In the technology, when the middle table top 1 ascends or descends, the front lifting mechanism 11 and the rear lifting mechanism 21 synchronously work at the same time, and cylinders of the front lifting mechanism 11 and the rear lifting mechanism 21 are connected with electromagnetic valves of the same type. By utilizing the control of the electromagnetic valve, on one hand, the synchronous control of the front lifting mechanism 11 and the rear lifting mechanism 21 is facilitated, on the other hand, the stepless adjustment is realized, the middle table top can be lifted to any proper height, and the adjustment is convenient and rapid.

Based on the above technical solution, when the middle table top 1 needs to be tilted, as shown in fig. 6, the front lifting mechanism 11 and the rear lifting mechanism 21 work synchronously at the same time, and lift the middle table top by a certain distance, so that the middle table top 1 is separated from the table tops 3 at the two end portions, thereby avoiding interference in tilt adjustment, then the front lifting mechanism 11 stops working, the left air cylinder 112 and the right air cylinder 112 of the rear lifting mechanism 21 work synchronously at the same time, and the middle table top 1 is tilted forward. If the middle table top 1 needs to be reset from an inclined state, the rear lifting mechanism 21 needs to descend firstly, the rear middle table top is horizontal, then the front lifting mechanism 11 and the rear lifting mechanism 21 synchronously work simultaneously, and the middle table top 1 needs to be reset downwards and horizontally.

As shown in fig. 1 to 3, a mounting seat 12 is provided at the bottom of the middle table-board 1, and the push rods of the left air cylinder 111 and the right air cylinder 112 are respectively connected with the mounting seat 12 through a universal cross joint (existing parts of the universal cross joint, not shown in detail).
