[0029] Example:

[0030] See also Figure 1 - Figure 4 A expandable intelligent center console comprises a center console body 1 and a display screen body 2. A mounting groove 11 is provided on one side of the center console body 1. The display screen body 2 is slidably arranged inside the mounting groove 11. A telescopic rotation mechanism 3 is arranged inside the mounting groove 11. The telescopic rotation mechanism 3 comprises a fixing frame 30 and three No. 2 tooth rings 35 fixedly connected to one side of the inner wall of the center console body 1. A telescopic frame 31 is rotatably arranged on the top of the fixing frame 30. No. 1 circular grooves 32 are provided on both sides of the telescopic end of the telescopic frame 31. No. 2 circular grooves 33 are provided on the bottom surface of the fixed end of the telescopic frame 31. Rotating components 34 are arranged inside the two No. 1 circular grooves 32 and the No. 2 circular grooves 33. One side of the display screen body 2 is fixedly connected to one end of two of the No. 2 tooth rings 35, and the top surface of the fixing frame 30 is fixedly connected to the bottom surface of the other No. 2 tooth ring 35.

[0031] Specifically, the rotating assembly 34 includes a rotating shaft 341 which is fixedly connected to one side of the inner wall of the two No. 1 circular grooves 32 and one side of the inner wall of the No. 2 circular groove 33 respectively. A spring telescopic rod 342 is sleeved on the outside of the rotating shaft 341, and one end of the spring telescopic rod 342 is fixedly connected to a No. 1 gear ring 343.

[0032] Specifically, the tooth ring surfaces of the three No. 1 tooth rings 343 are respectively meshed with the tooth ring surfaces of the three No. 2 tooth rings 35, wherein one end of two spring telescopic rods 342 is fixedly connected to one side of the inner wall of the No. 1 circular groove 32, one end of the other spring telescopic rod 342 is fixedly connected to the top surface of the inner wall of the No. 2 circular groove 33, and the other ends of the three spring telescopic rods 342 are respectively fixedly connected to one side of the three No. 1 tooth rings 343.

[0033] In this solution, the display screen body 2 can be extended from the installation groove 11 by a certain distance through the telescopic frame 31, and the telescopic frame 31 can be used to achieve multi-angle adjustment. When adjusting up and down, the teacher pushes the display screen body 2 with his hand. At this time, the display screen body 2 is pushed by the teacher, and the two No. 2 snap rings 35 installed on the telescopic frame 31 will rotate relative to the No. 1 snap ring 343. At this time, the No. 1 snap ring 343 will be pushed by the No. 2 snap ring 35 to shrink into the No. 1 circular groove 32, and at the same time, the spring telescopic rod 342 is squeezed and produces The spring telescopic rod 342 will repeatedly release the elastic force to make the second snap ring 35 constantly mesh with the first snap ring 343, so that the display screen body 2 can be kept fixed and will not slide after adjustment through the meshing and limiting effect between the first snap ring 343 and the second snap ring 35, making it more convenient for the teacher to adjust. When adjusting left and right, similarly, the rotating assembly 34 inside the second circular groove 33 and the second snap ring 35 on the top surface of the fixing frame 30 cooperate with each other, which can also keep the display screen body 2 fixed and will not slide after adjustment.

[0034] By setting up the telescopic rotation mechanism 3, it is convenient for teachers to adjust the display screen body 2 at multiple angles, and the display screen body 2 can remain fixed after adjustment. There is no need to reduce the light intensity in the classroom to clearly see the content on the display screen body 2. The adjustment method is simple and quick, and does not require teachers to expend energy. It can enable teachers to focus more on the classroom, thereby improving the quality of teachers' teaching.

[0035] See also Figure 1 - Figure 4 Both sides of the inner wall of the mounting groove 11 are fixedly connected with slide rails 4 , and two anti-falling mechanisms 5 are arranged between the two slide rails 4 and the display screen body 2 .

[0036] Specifically, the anti-falling mechanism 5 includes two No. 1 fixing seats 51 fixedly connected to one side of the inner wall of the installation groove 11 and a No. 2 fixing seat 54 fixedly connected to one side of the display screen body 2. The middle parts of the two No. 1 fixing seats 51 are both slidably connected with spring rods 52. The ends of the two spring rods 52 close to the slide rail 4 are fixedly connected to the limiting balls 53. The No. 2 fixing seat 54 is fixedly connected to the side close to the slide rail 4 with a sliding disc 55.

[0037] Specifically, the sliding disc 55 is slidably connected to the slide rail 4 , the minimum distance between the two limiting balls 53 is smaller than the diameter of the sliding disc 55 , and the maximum distance between the two limiting balls 53 is larger than the diameter of the sliding disc 55 .

[0038] Specifically, a buckle groove 21 is formed on a side of the display screen body 2 away from the mounting groove 11 and close to the bottom edge.

[0039] When the display screen body 2 is located inside the mounting groove 11, the sliding disc 55 is located inside the sliding rail 4, which plays a role in limiting the display screen body 2. When the teacher needs to take out the display screen body 2, the teacher can manually pull the buckle groove 21 to pull the display screen body 2 out to the outside of the mounting groove 11. During the pulling-out process, the sliding disc 55 will gradually contact the two limiting balls 53 and push the two limiting balls 53 to the upper and lower sides, and squeeze the spring rod 52 until the diameter of the sliding disc 55 is the same as the spacing between the two limiting balls 53. The spring rod 52 releases the elastic force and pushes the sliding disc 55 out of the sliding rail 4, thereby making the display screen body 2 escape from the restriction of the sliding rail 4 and able to adjust the angle left and right. When the display screen body 2 is located inside the mounting groove 11, if the teacher accidentally hits the podium during the interaction with students in the classroom, the limiting ball 53 and the spring rod 52 can also prevent the sliding disc 55 from detaching from the sliding rail 4, thereby avoiding the display screen body 2 from falling off.

[0040] Working principle: When the teacher wants to take out the display screen body 2, the teacher first pulls the buckle groove 21 by hand to pull the display screen body 2 outward from the installation groove 11. During the pulling-out process, the sliding disc 55 gradually contacts the two limiting balls 53 and pushes the two limiting balls 53 to the upper and lower sides, and squeezes the spring rod 52 until the diameter of the sliding disc 55 is the same as the distance between the two limiting balls 53. Then, the spring rod 52 releases the elastic force and pushes the sliding disc 55 out of the slide rail 4, and then the display screen body 2 can be adjusted at multiple angles.

[0041] When adjusting up and down, the teacher pushes the display screen body 2 with his hand. At this time, the display screen body 2 is pushed by the teacher, and the two No. 2 toothed rings 35 installed on the telescopic frame 31 will rotate relative to the No. 1 toothed ring 343. At this time, the No. 1 toothed ring 343 will be pushed by the No. 2 toothed ring 35 to shrink into the No. 1 circular groove 32. At the same time, the spring telescopic rod 342 is squeezed and generates elastic force. The spring telescopic rod 342 will repeatedly release the elastic force to make the No. 2 toothed ring 35 continuously mesh with the No. 1 toothed ring 343, so that the display screen body 2 can remain fixed and will not slide after adjustment through the meshing and limiting effect between the No. 1 toothed ring 343 and the No. 2 toothed ring 35, making it more convenient for the teacher to adjust; when adjusting left and right, similarly, the rotating component 34 inside the No. 2 circular groove 33 and the No. 2 toothed ring 35 on the top surface of the fixing frame 30 cooperate with each other, which can also keep the display screen body 2 fixed and will not slide after adjustment.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
