DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 2 as well as Figure 4 A multimodal interactive device based on English teaching, comprising a support base 2 fixed with a plurality of support rods 1, a universal wheel is rotatably mounted on the lower end of each support rod 1, a circular disc is mounted on the support base 2 through a height adjustment mechanism, and a through hole 35 matching the circular disc is opened on the support base 2;

[0032] The following points are worth noting:

[0034] The upper ends of the two lifting frames 4 are fixedly mounted with a mounting plate 6, a fixing rod 7 is fixedly mounted on the front side of the mounting plate 6, and one end of the fixing rod 7 is connected to the circular plate body, a servo motor 11 is fixedly mounted in the mounting cavity 10, a rotating rod 12 is fixedly mounted on the driving end of the servo motor 11, two gears 13 are fixedly mounted on the rotating rod 12, and the gears 13 are meshed with the lifting frames 4;

[0035] The height adjustment mechanism is used to control the height adjustment of the lifting frame 4 in the vertical direction, and the height adjustment mechanism is easy to operate and only needs to control the operation of the servo motor 11 .

[0036] 2. Specifically, the servo motor 11 can be controlled by a controller, and the controller can be a PLC controller.

[0037] 3. A stopper 5 is fixedly mounted at the lower end of each lifting frame 4, and the size of the stopper 5 is larger than the size of the vertical hole 3; the setting of the stopper 5 limits the upward movement of the lifting frame 4, and also improves the stability of the device when in use (at this time, the upper surface of the stopper 5 is in contact with the lower surface of the support 2).

[0038] 4. An elastic ring 34 is fixedly mounted on the circular plate body. The elasticity of the elastic ring 34 can improve the safety of the circular plate body and the comfort during use;

[0039] The elastic ring 34 can be made of rubber material.

[0040] 5. The length of the through hole 35 is smaller than the diameter of the circular disk, so that when the circular disk moves downward to the lowest position, the through hole 35 and the circular disk will come into contact, thus providing a certain support effect for the circular disk.

[0041] Reference Figure 1 , Figure 6 The circular plate body is composed of a semicircular plate 14 and a semicircular plate 15 fixedly fixed. A groove 16 is provided on the front side of the semicircular plate 15. A support plate 17 is rotatably installed in the groove 16. A fixed structure is installed between the semicircular plate 15 and the support plate 17.

[0042] A video player 23 is fixedly mounted on the semicircular plate 14;

[0043] The following points are worth noting:

[0044] 1. The fixed structure is composed of a vertical groove 18, a knob 19, a rod body 20, a block 21, a cavity 22, a connecting circular hole and a circular shaft. A connecting circular hole matching the groove body 16 is provided on the semicircular plate 15, and a circular shaft is rotatably installed in the connecting circular hole.

A vertical groove 18 matching the knob 19 and the block 21 is provided on the support plate 17, and two cavities 22 are also provided on the semicircular plate 15, and the cavities 22 are connected to the vertical groove 18;

[0045] The setting of the fixing structure enables the support plate 17 to quickly form a fixed state with the semicircular plate 2 15 when needed, thereby facilitating the use of the whole.

[0046] 2. The video player 23 is a prior art, and its specific structure and principle are not elaborated here. It is used to play videos, etc., so that students can understand the knowledge points of this part more vividly.

[0047] 3. In the initial state, the support plate 17 is fixedly connected to the second semicircular plate 15 through a fixed structure. At this time, writing can be done directly on the second semicircular plate 15. When the corresponding items need to be displayed, it is rotated so that it is perpendicular to the second semicircular plate 15, thereby facilitating the placement of the corresponding items.

[0048] Reference Figure 1 , Figure 3 , Figure 5 as well as Figure 6 The backs of the semicircular plate 14 and the semicircular plate 2 15 are provided with two slots 24, the support base 2 is provided with an arc-shaped slot 25, the support base 2 is provided with two circular sliding holes, and the two circular sliding holes are connected with the arc-shaped slot 25 and the through hole 35, and a round rod 29 is installed in the two circular sliding holes through a sliding support assembly;

[0049] A rotating shaft is rotatably installed in the arc groove 25, and a reciprocating structure is installed between the rotating shaft and the round rod 29;

[0050] A rotating assembly is installed between the rotating shaft and the arc groove 25;

[0051] The following points are worth noting:

[0052] 1. The sliding support assembly is composed of a strip-shaped slider and a strip-shaped slide groove. A plurality of strip-shaped sliders are fixedly mounted on the two round rods 29, and a strip-shaped slide groove matching the strip-shaped slider is provided on the inner walls of the two round sliding holes.

[0053] 2. The reciprocating structure is composed of a rod body 26, a circular magnetic block 1 28 and a circular magnetic block 2. Two rod bodies 26 are fixedly installed on the rotating shaft. One end of the two rod bodies 26 is fixedly installed with a circular magnetic block 1 28, and the magnetic properties of the two circular magnetic blocks 1 28 on the same side are opposite. The ends of the two round rods 29 close to the rod body 26 are fixedly installed with circular magnetic blocks 2, and the magnetic properties of the two circular magnetic blocks 2 on the side close to the rod body 26 are opposite.

[0054] 3. The rotating assembly consists of a gear 27, a stepped slide 30, a stepped slider 31 and a gear rod 32. The rotating shaft is mounted with the gear 27 through a one-way bearing. The gear 27 is meshed with the gear rod 32. The stepped slider 31 is fixedly mounted on the inner wall of the arc groove 25. The gear rod 32 is provided with a stepped slide 30 that matches the stepped slider 31.

[0055] 4. A plate body 33 is fixedly mounted on the upper end of the gear rod 32.

[0056] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0057] In the present invention, Figure 1 The figure shows the state when in use. At this time, the semicircular plate 2 15 is at the top and can be used directly for writing. When the video player 23 is needed, an upward force is applied to the plate body 33, and the plate body 33 moves upward and drives the shaft to rotate through the gear 2 27 (at this time, the one-way bearing is in a self-locking state) (the plate body 33 moves downward and will not drive the shaft to rotate under the action of the one-way bearing). The shaft rotates and drives the circular magnetic block 1 28 to rotate 180° through the rod body 26. At this time, the magnetic force on the round rod 29 is converted from the initial repulsion to attraction. The round rod 29 is moved toward the direction close to the circular magnetic block 1 28 (when they are closest, the two are not in contact), so that one end of the round rod 29 is moved out of the corresponding slot 24, and then a rotation force is applied to the circular plate body, so that the semicircular plate 1 14 is rotated to the top of the semicircular plate 2 15 (rotated 180 degrees), so that the video player 23 is at a suitable height for use. At this time, an upward moving force is applied to the plate body 33, so that one end of the round rod 29 can be engaged with the corresponding slot 24 (the slot 24 on the semicircular plate 2 15);

[0058] When the device is not in use, an upward force is applied to the plate body 33 again, so that one end of the round rod 29 leaves the slot 24, and then the servo motor 11 is turned on. The servo motor 11 drives the gear 13 to rotate through the rotating rod 12. The rotation of the gear 13 drives the lifting frame 4 engaged therewith to move downward. The lifting frame 4 moves downward and drives the circular plate body to move downward through the mounting plate 6 and the fixing rod 7, thereby reducing the space occupied by the entire device during placement or transportation.
