Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Embodiment 1:

[0034] As Figures 1 to 10 shown, this remote intelligent teaching device for preschool intellectual education of the present invention includes a moving component 1, a demonstration component 2 and a remote component 3. The demonstration component 2 is installed on the moving component 1, and the remote component 3 is installed above the demonstration component 2. The moving component 1 includes a driving member 11 and moving wheels 12, and the driving member 11 is connected to the moving wheels 12. The moving component 1 is used for the moving transportation of the remote intelligent teaching device. The demonstration component 2 includes a first main body 21, a demonstration screen 22 and a robotic arm 23. The remote component 3 includes a second main body 31 and an arc-shaped member 32. The first main body 21 is rotatably connected above the driving member 11, and a power source inside the driving member 11 is connected to the first main body 21. A robotic arm 23 is also connected to the first main body 21, and a power source inside the first main body 21 is connected to the robotic arm 23. A demonstration screen 22 is installed in the middle of the first main body 21. The demonstration screen 22 is used to play daily teaching videos, and the demonstration screen 22 is a touch screen. The second main body 31 is rotatably connected above the first main body 21, and the second main body 31 is connected to the power source inside the first main body 21. An arc-shaped member 32 is connected to the second main body 31, and a plurality of cameras 33 are installed on the arc-shaped member 32. The cameras 33 are used for remote transmission of live pictures.

[0035] In this embodiment, the specific steps of this remote intelligent teaching device of the present invention are as follows: Move the remote intelligent teaching device to the required position through the moving component 1, and then turn on the demonstration screen 22 to play daily teaching videos. When playing the teaching video, the first main body 21 and the robotic arm 23 will interact with the played teaching video, increasing the fun of children during learning. At the same time, through network connection, the live video captured by the camera 33 can be uploaded to the remote terminal, facilitating teachers to promptly discover unexpected situations. Among them, the second main body 31 can also rotate 75° clockwise or counterclockwise, increasing the shooting field of view of the camera 33.

[0036] Embodiment Two:

[0037] Existing educational devices can only teach unidirectionally and cannot provide effective feedback during teaching. To improve the teaching interaction effect of the remote intelligent teaching device in the present invention, a feedback component 4 is also installed on the robotic arm 23. As Figures 2 to 4 shown, the feedback component 4 includes a mounting portion 41, a fixing portion 42, a connecting portion 43, and a feedback portion 44. The mounting portion 41 is fixedly connected to the robotic arm 23, the fixing portion 42 is fixedly connected to the mounting portion 41, and the fixing portion 42 is connected to the feedback portion 44 through the connecting portion 43. Among them, the feedback component 4 has two states. In the first state, the fixing portion 42 and the feedback portion 44 are rigidly connected; in the second state, the fixing portion 42 and the feedback portion 44 are flexibly connected.

[0038] The fixing portion 42 includes a first housing 422, and a plurality of fixing members 423 are connected inside the first housing 422. An installation frame 424 is fixedly connected to the fixing member 423, and the installation frame 425 supports and connects a linear motor 425. The number of linear motors 425 corresponds to the number of fixing members 423, and the axis lines of the output shafts of the plurality of linear motors 425 are located in different cross-sections. This remote intelligent teaching device of the present invention adopts the technical solution with the lowest cost, and at least three linear motors 425 are installed inside the fixing portion 42. As Figure 8 shown, the linear motors 425 are arranged in a staggered manner at a 120° angle. The output shaft of the linear motor 425 is connected to a sprocket 426, a chain 427 is connected to the sprocket 426, a pulling rope 429 is provided above the chain 427, and the pulling rope 429 is fixedly connected to the feedback portion 44. Among them, the linear motor does not adopt the traditional pulley transmission to save costs, but instead chooses to install a chain and a sprocket on the output shaft of the motor for transmission. The transmission performance of the chain and sprocket is much higher than that of the pulley transmission. However, to control the production cost, only a part of the chain 427 is connected to the sprocket 426, and the rest is connected by the pulling rope 429, which not only improves the transmission performance but also effectively controls the cost.

[0039] As Figures 2 to 6As shown, the feedback unit 44 includes a second housing 443, on which a plurality of extrusion balls 442 are mounted. Above the second housing 443, an air pump 444 is also connected. A plurality of extrusion balls 442 penetrate through the second housing 443 and are connected to the air pump 444. Below the air pump, a piston 445 is slidably connected, and a controller 446 is mounted directly below the piston 445. When the air inside the extrusion ball 442 enters the air pump 444, the compressed air pushes the piston 445 downward. When the piston 445 contacts the controller 447, after the controller 447 receives the signal, it controls the feedback assembly 4 to switch from the first state to the second state. In the second state, the feedback unit 44 can drive the linear motor 425 to rotate by stretching 429 whether it bends, rotates or stretches.

[0040] As Figure 10 shown, a magnetic induction shaft 428 is installed inside the linear motor 425, and the magnetic induction shaft 428 is fixedly connected to the sprocket 426. When the magnetic induction shaft 428 rotates, the air gap between the magnetic induction shaft 428 and the magnetic head changes, the magnetic flux also changes, and the induced electromotive force also changes accordingly, so as to be transmitted to the feedback unit 44 through the pull rope 429. Moreover, the linear motor 425 is also provided with a pre-tightening force to keep the chain 427 and the pull rope 429 always in a straightened state. Among them, the fixing part 42 and the feedback unit 44 adopt the above technical solution, rather than the traditional hinge connection solution. The main reason is that the hinge connection solution for transmission limits the rotation direction of the feedback unit. The feedback unit 44 can only rotate in one direction, reducing the interactive practicability. The feedback unit in the above technical solution can be bent at any angle. At the same time, compared with the universal ball connection method, the technical solution of the present invention has a simpler structure and lower production cost.

[0041] As Figures 3 to 4 shown, a first rubber sleeve 421 is fixedly connected to the outside of the first housing 422, and a third rubber sleeve 441 is fixedly connected to the outside of the second housing 443. The first rubber sleeve 421 is connected to the third rubber sleeve 441 through the second rubber sleeve 431. The first rubber sleeve 421, the second rubber sleeve 431 and the third rubber sleeve 441 are of an integral structure. And the second rubber sleeve 431 is in a corrugated shape, and the second rubber sleeve 431 has good bending and stretching extensibility. Moreover, the second rubber sleeve 431 can also limit the rotation angle of the feedback unit 44, so that the feedback unit 44 can only rotate slightly by 0 to 20°.

[0042] In this embodiment, the specific operation steps of the feedback component 4 are as follows: The initial state of the feedback component 4 is the first state, that is, the feedback component 4 is in a rigid state. After holding the feedback part 44, the squeezing ball 442 sends compressed air into the air pump 444. The compressed air pushes the piston 445 to move downward. The piston 445 contacts the controller 447. After receiving the signal, the controller 447 controls the feedback component 4 to switch from the first state to the second state. At this time, the feedback component 4 can be bent, rotated or stretched. Finally, through the cooperation of the feedback part 44 and the pull rope 429, the magnetic induction shaft 428 in the linear motor 425 is driven to rotate. The linear motor 425 senses different dynamic changes of the feedback part 44 and gives different magnetic induction feedback, greatly improving the feedback performance of the teaching equipment and enhancing the fun of children's learning at the same time.

[0043] Embodiment Three:

[0044] In this embodiment, the fixing part 42 and the feedback part 44 are only connected by the first rubber sleeve 421, the second rubber sleeve 431 and the third rubber sleeve 441, and the connection is not reliable. Therefore, the connecting part 43 is used to connect the fixing part 42 and the feedback part 44. The connecting part 43 includes a plurality of first flexible steel ropes 432 and a plurality of second flexible steel ropes 435. The fixing part 42 is connected to the feedback part 44 through a plurality of first flexible steel ropes 432 and a plurality of second flexible steel ropes 435. One end of the plurality of first flexible steel ropes 432 and the plurality of second flexible steel ropes 435 is fixedly connected to the first outer shell 422, and the other end is fixedly connected to the second outer shell 443. As Figure 3 or Figure 4 shown, four first flexible steel ropes 432 are connected to the middle of the fixing part 42, and four second flexible steel ropes 434 are also connected to both sides of the fixing part 42, and the first flexible steel ropes 432 and the second flexible steel ropes 435 have elasticity when stretched.

[0045] As Figure 7 shown, the connecting part 43 further includes a plurality of first electric push rods 433 and a plurality of second electric push rods 434. The number of the first electric push rods 433 and the second electric push rods 434 corresponds to the number of the second flexible steel ropes 434. The second flexible steel rope 435 is of a hollow structure, and the output shafts of the first electric push rod 433 and the second electric push rod 434 are located in this hollow structure. The first electric push rod 433 is connected inside the second outer shell, and the second electric push rod 434 is connected inside the first outer shell.

[0046] The controller 447 controls the output strokes of the first electric push rod 433 and the second electric push rod 434, that is, controls the elongation strokes of the output shafts of the first electric push rod 433 and the second electric push rod 434. The first electric push rod 433 and the second electric push rod 434 control the switching between two states of the feedback assembly 4. In the first state, the first electric push rod 433 and the second electric push rod 434 are in the extended state; in the second state, the first electric push rod 433 and the second electric push rod 434 are in the retracted state.

[0047] As Figure 7 shown, magnet blocks 436 are provided on the output shafts of the first electric push rod 433 and the second electric push rod 434, and the two magnet blocks 436 attract each other. In the first state, the two magnet blocks 436 attract each other, and the angular rotation of the output shafts of the first electric push rod 433 and the second electric push rod 434 is restricted by the magnetic force of the magnet blocks 436, that is, the feedback part 44 cannot be bent. In the second state, the output shafts of the first electric push rod 433 and the second electric push rod 434 are in the retracted state, that is, the feedback part 44 can be bent at any angle.

[0048] In this embodiment, as Figures 3 to 5 shown, the feedback assembly 4 further includes a touch part 45, and the touch part 45 is located above the feedback part 44. The touch part 45 includes a fourth rubber sleeve 451, the fourth rubber sleeve 451 is fixedly connected to the third rubber sleeve 441, and a tetrahedral ball 452 is installed inside the fourth rubber sleeve 451. The tetrahedral ball 452 has a regular tetrahedron structure, and a plurality of roller rods 453 are installed on the tetrahedral ball 452. By adding the touch part 45 to provide a richer and more complex learning environment, it can further promote the increase in the volume of cerebral cortex cells in young children, and the connections between cells also increase accordingly, which can more effectively stimulate the potential development of young children.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
