[0002] In current engineering and technical education at various universities, vocational colleges, and technical schools, the common practice is to use simple teaching models or simply write on the blackboard, draw 3D diagrams, and use corresponding illustrations for explanation. This teaching method has the following problems: 1. Due to the lack of teaching model demonstrations, simple explanations are insufficient to create a complete physical image in students' minds, resulting in poor explanation effectiveness. 2. The homework, textbooks, pens, ink, paper, and other materials used by students cause significant waste of national resources every year and also seriously pollute our living environment.

[0003] To address the above problems, the following teaching experimental platform has been developed using existing technology:

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1-5 As shown, the teaching experimental platform integrating teaching, scientific research and practice includes a platform body for placing experimental teaching aids. The platform body includes a lifting platform 1, a flipping walking mechanism set on the lifting platform 1 and a camera 5 set on the flipping walking mechanism. The camera 5 communicates with the display terminal.

[0038] The tilting walking mechanism includes a longitudinal walking unit 7 that travels along the length of the lifting platform 1, a tilting unit 2 connected to the output end of the longitudinal walking unit 7, and an arc-shaped walking unit 6 connected to the output end of the tilting unit 2. The output end of the arc-shaped walking unit 6 is equipped with a camera 5, and the arc-shaped walking unit 6 is located above the lifting platform 1.

[0039] Preferably, the lifting platform 1 includes a demonstration platform 11, a support frame 12, and a base 13 arranged sequentially from top to bottom, with sufficient space between the demonstration platform 11 and the base 13 for accommodating the arc-shaped walking unit 6. The longitudinal walking unit 7 includes two longitudinal slide rails 72 fixed to both sides of the bottom of the demonstration platform 11, a positioning iron bar 71 arranged parallel to the longitudinal slide rails 72, and a moving platform 73. One side of the moving platform 73 is slidably connected to the longitudinal slide rails 72 via a slider, and the side of the moving platform 73 facing the longitudinal slide rails 72 is also magnetically positioned and connected to the positioning iron bar 71 via an electromagnet. In this embodiment, the moving platform 73 is a manually movable platform 73 that is slidably set on the slide rails. Through the above structure, when the electromagnet is energized, it can generate an electromagnetic attraction between itself and the positioning iron bar 71, locking the transverse moving platform 73 and preventing it from moving along the transverse slide rails, thus achieving the positioning purpose.

[0040] Preferably, the flipping unit 2 includes a flipping joint module disposed on the mobile platform 73, and the output end of the flipping joint module is connected to the arc-shaped walking unit 6 in sequence via a horizontal connecting rod and a lifting unit 3.

[0041] Preferably, the lifting unit 3 includes a bottom lifting rod 31 with its bottom end vertically connected to the end of the horizontal connecting rod away from the flip joint module, a top lifting rod 35 with its top end vertically slidably connected to the bottom lifting rod 31, and a drive assembly for driving the top lifting rod 35 to slide along the bottom lifting rod 31. The drive assembly includes a lifting drive motor 33 fixed inside the top lifting rod 35 via a lifting connecting plate, a transmission gear 34 connected to the output end of the lifting drive motor 33, and a vertical rack 32 meshing with the transmission gear 34. The vertical rack 32 is fixed on the inner wall of the bottom lifting rod 31, so that after the motor shaft of the lifting drive motor 33 is reversed by the worm gear reducer, the output shaft of the worm gear reducer is connected to the transmission gear 34, and the transmission gear 34 and the rack mesh. Under the action of the gear and rack, the lifting movement of the top lifting rod 35 is realized.

[0042] The lifting drive motor 33 is a worm gear reducer, which includes a worm reducer. It uses the worm wheel and worm to lock itself, thus preventing the motor from reversing after it stops.

[0043] Preferably, a vertical guide rail is fixed on the inner wall of the lifting column, and a vertical guide slider is fixed on the lifting connecting plate at the position corresponding to the vertical guide rail, and the vertical guide slider is slidably connected to the vertical guide rail.

[0044] Preferably, the arc-shaped walking unit 6 includes an arc-shaped mounting plate 66, an arc-shaped slide rail 64 fixed to one side of the arc-shaped mounting plate 66, a drive wheel 69, a plurality of guide wheels 68, and a driven wheel 67 rotatably disposed on the other side of the arc-shaped mounting plate 66. The drive wheel 69, the plurality of guide wheels 68, and the driven wheel 67 form an arc with the same curvature as the arc-shaped slide rail 64. The drive wheel 69 is concentrically connected to a first transmission bevel gear 63, the first transmission bevel gear 63 meshes with a second transmission bevel gear 62, and the second transmission bevel gear 62 is connected to the output shaft of a walking drive motor 61 fixed on a transverse rotating shaft. The drive wheel 69, the plurality of guide wheels 68, and the driven wheel 67 are connected by a transmission rope. The transmission rope is connected to an extension unit 4 through an arc-shaped guide hole 65 opened on the arc-shaped mounting plate 66. The extension unit is also slidably connected to the arc-shaped slide rail 64.

[0045] In this embodiment, the drive wheel 69, driven wheel 67, and guide wheel 68 are all grooved round wheels. Since the diameter of the grooved round wheel is small, but the yaw motion angle is large and the arc motion stroke is long, in order to achieve the purpose of long stroke, the drive wheel 69 and driven wheel 67 are both wound with a multi-turn transmission rope. After the transmission rope is wound with multiple turns, it is fixed in the stepped hole opened on the drive wheel 69 or driven wheel 67.

[0046] The principle of arc movement is as follows: the walking drive motor 61 drives the drive wheel 69 to rotate in sequence through the second bevel gear and the first bevel gear. During the rotation of the drive wheel 69, the transmission rope wrapped around it is loosened or tightened. At the same time, in coordination with the driven wheel 67 located at the other end of the transmission rope (if the transmission rope on the drive wheel 69 is continuously loosened, the transmission rope on the driven wheel 67 is continuously wrapped, and vice versa), the transmission rope can be driven to move in an arc along the guide wheel 68. During its movement, it drives the translation probe unit to move in an arc, thereby completing the arc transmission.

[0047] Preferably, the extension unit 4 includes a linear module connected to a transmission rope. The output end of the linear module is connected to a camera 5. The outer side of the linear module away from the camera 5 is fixedly connected to one end of a double-ended screw via a wedge. The other end of the double-ended screw passes through an arc-shaped guide hole 65 and is then fixedly connected to the transmission rope. This is used to open the linear module during focused teaching, controlling the camera 5 to move towards the observation position for easy highlighting.

[0048] Preferably, both ends of the longitudinal slide rail 72 are provided with stops to prevent the moving platform 73 from dislodging from the longitudinal slide rail 72.

[0049] Preferably, locking wheels 14 are rotatably provided at the four corners of the bottom of the base 13 for easy movement.

[0050] It should be noted that the above-mentioned electronic components are all mature products on the market. In this embodiment, it is only necessary to purchase them and connect them according to the instruction manual. Furthermore, the principle of controlling the forward and reverse rotation of the motor is common knowledge in the field, so it will not be described in detail here.

[0051] Therefore, the present invention adopts a teaching experimental platform that integrates teaching, scientific research and practice with the above-mentioned structure. By using a flip-type walking mechanism, the camera can be flipped to the top of the platform body during teaching, so that students can watch and learn through the display terminal. During scientific research and practice, the camera can be flipped to the bottom of the platform body, so that it can be operated on the platform body.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
