Description

Technical Field

[0001] This invention relates to the field of teaching equipment technology, and more specifically, to a children's animation teaching device. Background Technology

[0002] Children's animation education aims to enlighten and educate children by demonstrating teaching content. In the process of children's animation teaching demonstration, a multimedia projection screen is often required to carry out multimedia teaching demonstrations.

[0003] Chinese patent application CN110491192A discloses a teaching demonstration device for animation design. It uses an adjustable movable screen and a motor drive mechanism to drive the projection screen to retract and extend. It can also drive the projection screen and the teaching board to move horizontally at the same time, which facilitates multimedia teaching demonstrations and makes it easier for students to view the teaching content on the teaching board. While the aforementioned patent allows for adjustment of the screen's position, it does not allow for adjustment of the screen's tilt angle. This is also true for most traditional screens, which are fixed in the center of the classroom and cannot be adjusted in angle. This results in a poor viewing experience for students on both sides of the classroom, thus affecting the quality of teaching. Furthermore, when the teaching task is completed, traditional screens can only be rolled up, and the rolled-up screen will obstruct the view of students in the back rows.

[0004] Therefore, a children's animation teaching device is proposed. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a children's animation teaching device that can adjust the angle and position, so as to take care of students in every position in the classroom. Adjusting the position and angle according to the student's position improves the viewing experience.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A children's animation teaching device includes two sets of fixed plates, with a housing fixedly installed between the two sets of fixed plates.

A universal joint transmission mechanism is provided between the displacement transmission mechanism and the support plate. An angle adjustment mechanism is provided on the upper end of the support plate. A winding and cleaning mechanism is provided between the take-up roller and the universal joint transmission mechanism. The universal joint transmission mechanism is connected to the displacement transmission mechanism, and the winding and cleaning mechanism is also connected to the universal joint transmission mechanism. The displacement transmission mechanism uses output shaft one as a power source to adjust the position of the support plate, allowing the support plate to carry the curtain and adjust its position. The angle adjustment mechanism uses output shaft two as a power source to adjust the deflection angle of the support plate, allowing the support plate to carry the curtain and adjust its deflection angle. The universal joint transmission mechanism uses the displacement transmission mechanism as a power source and transmits power to the winding and cleaning mechanism, ensuring that the winding and cleaning mechanism can be driven regardless of the angle to which the support plate carrying the curtain deflects. The winding and cleaning mechanism drives the winding roller, causing the winding roller to wind up or unwind the curtain as the support plate moves.

[0008] Furthermore, the displacement transmission mechanism includes a threaded rod fixedly installed at the right end of the output shaft, the threaded rod being rotatably connected to the inner right end of the housing, the outer surface of the threaded rod being helically connected to a threaded sleeve, and a slide rail being provided at the front end of the outer surface of the housing.

[0010] Furthermore, the angle adjustment mechanism includes a support rod 1 fixedly installed at the lower end of the threaded sleeve, a support rod 2 fixedly installed at the upper end of the threaded sleeve, and a support rod 3 fixedly installed on the lower side of the rear end face of the support plate. Both support rod 1 and support rod 2 are L-shaped. The upper and lower ends of the outer surface of the outer shell are provided with sliding grooves corresponding to support rod 1 and support rod 2.

[0011] Furthermore, the angle adjustment mechanism also includes a rotating shaft three fixedly installed on the lower end face of the horizontal plate of the support plate, the rotating shaft three being rotatably connected to the support rod two, the upper end of the support rod three being fixedly installed with the rotating shaft two, the rotating shaft two being rotatably connected to the support rod one, a gear one being fixedly installed on the rear side of the upper end face of the horizontal plate of the support plate corresponding to the support rod two, a motor two being provided on the upper side of the support rod two, an output shaft two being provided on the lower end of the motor two, the output shaft two being rotatably connected to the support rod two, a fixing rod being fixedly installed on the rear end of the motor two, the fixing rod being fixedly connected to the support rod two, and a gear two being fixedly installed on the outer surface of the output shaft two, the gear two meshing with the gear one.

[0012] Furthermore, the universal joint transmission mechanism includes a universal joint fork one disposed on the front side of the housing corresponding to the sleeve, the sleeve being fixedly connected to the universal joint fork one, a rotating rod one being rotatably connected to the rear end of the support plate corresponding to the universal joint fork one, a universal joint fork two being fixedly installed at the rear end of the rotating rod one, and a cross pin being rotatably connected between the universal joint fork one and the universal joint fork two.

[0013] Furthermore, the universal joint transmission mechanism also includes a connector fixedly installed on the right side of the lower end face of the cross plate of the support plate. The lower end of the connector is rotatably connected to a rotating rod two. A gear four is fixedly installed on the left end of the rotating rod two. A worm gear is fixedly installed on the outer surface of the rotating rod one. The worm gear and the gear four mesh with each other.

[0014] Furthermore, the winding cleaning mechanism includes a gear five fixedly installed at the right end of the rotating rod two, and a gear six fixedly installed on the right side of the outer surface of the rotating shaft one, with the gear five and gear six meshing with each other.

[0015] Furthermore, the winding cleaning mechanism also includes a rotating rod three rotatably connected to the upper side of the slot inside the support plate, a gear seven fixedly installed on the right side of the outer surface of the rotating rod three, the gear seven meshing with the gear six, and a cleaning roller fixedly installed on the outer surface of the rotating rod three.

[0016] Furthermore, a cleaning brush is fixedly installed on the outer surface of the cleaning roller, and the cleaning roller is set in close contact with the take-up roller.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 10 A children's animation teaching device includes two sets of fixed plates 1, with a housing 2 fixedly installed between the two sets of fixed plates 1. A support plate 3 is provided on the front side of the housing 2. The support plate 3 is L-shaped and has a slot on its front end face. A rotating shaft 4 is rotatably connected inside the slot of the support plate 3. A take-up roller 5 is fixedly installed on the outer surface of the rotating shaft 4, and a screen 6 is wound around the outer surface of the take-up roller 5. A motor 7 is fixedly installed on the left end inside the housing 2. An output shaft 8 is provided on the right end of the motor 7. A displacement transmission mechanism is provided on the right side of the output shaft 8. A universal joint transmission mechanism is provided between the displacement transmission mechanism and the support plate 3. An angle adjustment mechanism is provided on the upper end of the support plate 3. A winding and cleaning mechanism is provided between the take-up roller 5 and the universal joint transmission mechanism. The transmission mechanism is connected to the displacement transmission mechanism, and the winding and cleaning mechanism is connected to the universal joint transmission mechanism. The displacement transmission mechanism uses output shaft 8 as the power source to adjust the position of the support plate 3, so that the support plate 3 carries the curtain 6 for position adjustment. The angle adjustment mechanism uses output shaft 20 as the power source to adjust the deflection angle of the support plate 3, so that the support plate 3 carries the curtain 6 for deflection angle adjustment. The universal joint transmission mechanism uses the displacement transmission mechanism as the power source and transmits it to the winding and cleaning mechanism to ensure that the winding and cleaning mechanism can be driven no matter what angle the support plate 3 carrying the curtain 6 is deflected to. The winding and cleaning mechanism drives the winding roller, so that the winding roller rolls up or unfolds the curtain 6 with the displacement of the support plate 3.

[0022] By adopting the above technical solution, this solution sets up a transmission displacement mechanism, an angle adjustment mechanism, a universal joint transmission mechanism, and a winding and cleaning mechanism. The output shaft 8 of motor 7 rotates to drive the support plate 3 to move. At the same time as the support plate 3 moves, it can also drive the universal joint transmission mechanism, which in turn drives the winding and cleaning mechanism, thereby unfolding or winding the curtain 6. The universal joint transmission mechanism ensures that no matter what angle the angle adjustment mechanism adjusts the support plate 3 to, the displacement transmission mechanism can drive the winding and cleaning mechanism through the universal joint transmission mechanism. The output shaft 20 of motor 18 is used as the power source, causing the output shaft 20 to carry gear 21 to rotate, thereby engaging gear 17 fixedly installed on the support plate 3, causing deflection and adjusting the tilt angle of the support plate 3.

[0023] like Figure 1 , Figure 7 and Figure 4 As shown, the displacement transmission mechanism includes a threaded rod 9 fixedly installed at the right end of the output shaft 8. The threaded rod 9 is rotatably connected to the inner right end of the housing 2. A threaded sleeve 10 is helically connected to the outer surface of the threaded rod 9. A slide rail 22 is provided at the front end of the outer surface of the housing 2. The displacement transmission mechanism also includes a rack 26 fixedly installed on the lower inner end face of the slide rail 22. A rotating shaft 23 is fixedly installed at the front end of the outer surface of the threaded sleeve 10. The rotating shaft 23 extends to the outside through the slide rail 22. A sleeve 24 is sleeved on the outer surface of the rotating shaft 23. A gear 25 is fixedly installed on the rear side of the outer surface of the sleeve 24. The gear 25 meshes with the rack 26.

[0024] By adopting the above technical solution, the traditional curtain 6 is fixedly installed in a certain place indoors. Although the curtain 6 is rolled up when not in use, it still affects the aesthetics of the room and obstructs the view. Therefore, this invention uses a transmission displacement mechanism to adjust the displacement of the support plate 3, enabling the curtain 6 to be rolled up, thus improving the versatility of the invention. Specifically, this invention is first fixed to the wall by two sets of fixing plates 1. When the curtain 6 needs to be moved, the motor 7 is first started, causing the output shaft 8 of the motor 7 to rotate, carrying the threaded rod 9. The threaded rod 9 is connected to a screw thread on its outer surface. The threaded sleeve 10 will move with the rotation of the threaded rod 9. The displacement of the threaded sleeve 10 will synchronously move the rotating shaft 23. The sleeve 24, which is rotatably connected to the outer surface of the rotating shaft 23, will move synchronously. The gear 25, which is fixedly installed on the rear side of the outer surface of the sleeve 24, will mesh with the rack 26 in the slide rail 22. As the sleeve 24 moves with the gear 25, the gear 25 will rotate under the action of the rack 26. The gear 25 will drive the sleeve 24 to rotate. The rotation of the sleeve 24 will drive the universal joint transmission mechanism, causing the universal joint transmission mechanism to operate and drive the winding and cleaning mechanism.

[0025] like Figure 3 , Figure 5 and Figure 10 As shown, the angle adjustment mechanism includes a support rod 11 fixedly installed at the lower end of the threaded sleeve 10, a support rod 2 12 fixedly installed at the upper end of the threaded sleeve 10, and a support rod 3 13 fixedly installed on the lower side of the rear end face of the support plate 3. Both support rod 11 and support rod 2 12 are L-shaped. Sliding grooves are provided on the upper and lower ends of the outer surface of the outer shell 2 corresponding to support rod 11 and support rod 2 12. Support rod 11 extends outward through the sliding groove at the upper end of the outer shell 2 and is positioned on the lower side of the horizontal plate of the support plate 3. Support rod 2 12 extends outward through the sliding groove at the lower end of the outer shell 2 and is positioned on the upper side of support rod 3 13. The angle adjustment mechanism also includes the lower end of the horizontal plate of the support plate 3. A rotating shaft 15 is fixedly installed on the surface of the support plate 3. The rotating shaft 15 is rotatably connected to the support rod 12. A rotating shaft 14 is fixedly installed on the upper end of the support rod 13. The rotating shaft 14 is rotatably connected to the support rod 11. A gear 17 is fixedly installed on the rear side of the upper end of the horizontal plate of the support plate 3, corresponding to the support rod 12. A motor 18 is set on the upper side of the support rod 12. An output shaft 20 is set on the lower end of the motor 18. The output shaft 20 is rotatably connected to the support rod 12. A fixing rod 19 is fixedly installed on the rear end of the motor 18. The fixing rod 19 is fixedly connected to the support rod 12. A gear 21 is fixedly installed on the outer surface of the output shaft 20. The gear 21 meshes with the gear 17.

[0026] By adopting the above technical solution, it should first be noted that the projection equipment in the classroom is fixedly connected to the support plate 3, thus allowing it to adjust its angle in sync with the support plate 3. The existing screen 6 cannot be adjusted in angle, which affects the viewing experience for students on both sides of the classroom. Therefore, this invention sets up an angle adjustment mechanism to allow the screen 6 and the projection mechanism to adjust their angles synchronously. Specifically: when angle adjustment is needed, the second motor 18 is started, causing the output shaft 20 of the second motor 18 to rotate, carrying the gear 21. The rotation of the gear 21 engages with the gear 17 fixedly installed on the support plate 3, thereby causing the support plate 3 to deflect. Shaft 2 14 and shaft 3 15 deflect within support rod 1 11 and support rod 2 12 as support plate 3 deflects, providing support for the deflection of support plate 3. This ensures that support plate 3 can deflect around shaft 2 14 and shaft 3 15 as gear 2 21 rotates, thereby adjusting the tilt angle of the screen 6 on support plate 3 for tilted display to students on both sides of the classroom, improving their viewing experience. Furthermore, when threaded sleeve 10 moves with the rotation of threaded rod 9, it simultaneously carries support rod 1 11 and support rod 2 12 with it. Support rod 1 11 is fixedly connected to support plate 3 via shaft 2 14, and support rod 2 12 is fixedly connected to support plate 3 via shaft 3 15. The fixed connection allows the support plate 3 to move synchronously when the threaded sleeve 10 moves, and the winding roller 5 and screen 6 on the support plate 3 move synchronously, thereby adjusting the position of the screen 6. When in use, the support plate 3 carrying the screen 6 is moved to the center of the classroom for projection viewing. When not in use, the support plate 3 carrying the screen 6 is moved to one side of the classroom to avoid affecting the students' normal teaching.

[0027] like Figure 5 and Figure 7 , Figure 8As shown, the universal joint transmission mechanism includes a universal joint fork 27 disposed on the front side of the housing 2 corresponding to the sleeve 24. The sleeve 24 is fixedly connected to the universal joint fork 27. A rotating rod 29 is rotatably connected to the rear end of the support plate 3 corresponding to the universal joint fork 27. A universal joint fork 28 is fixedly installed at the rear end of the rotating rod 29. A cross pin 16 is rotatably connected between the universal joint fork 27 and the universal joint fork 28. The universal joint transmission mechanism also includes a connector 31 fixedly installed on the right side of the lower end face of the cross plate of the support plate 3. A rotating rod 32 is rotatably connected to the lower end of the connector 31. A gear 33 is fixedly installed on the left end of the rotating rod 32. The outer surface of the rotating rod 29 is fixedly... A worm gear 30 is fixedly installed, and the worm gear 30 meshes with a gear 4 33. The winding cleaning mechanism includes a gear 5 34 fixedly installed on the right end of a rotating rod 2 32, and a gear 6 35 fixedly installed on the right side of the outer surface of a rotating shaft 1 4. The gear 5 34 and the gear 6 35 mesh with each other. The winding cleaning mechanism also includes a rotating rod 36 rotatably connected to the upper side of the slot inside the support plate 3. A gear 7 37 is fixedly installed on the right side of the outer surface of the rotating rod 3 36, and the gear 7 37 meshes with the gear 6 35. A cleaning roller 38 is fixedly installed on the outer surface of the rotating rod 3 36, and a cleaning brush is fixedly installed on the outer surface of the cleaning roller 38. The cleaning roller 38 is set close to the winding roller 5.

[0028] By adopting the above technical solution, when the sleeve 24 rotates, it synchronously drives the universal joint fork 27 to rotate. The universal joint fork 28, connected to the universal joint fork 27 via the cross pin 16, rotates synchronously. The rotation of the universal joint fork 28 carries the rotating rod 29 to rotate. When the angle adjustment mechanism causes the support plate 3 to deflect, the support plate 3 synchronously carries the rotating rod 29 to deflect, and the universal joint fork 28 synchronously follows the deflection of the rotating rod 29, rotating around the cross pin 16. When the sleeve 24 rotates, it drives the universal joint fork 27 to rotate. The rotation of the universal joint fork 27, through the cross pin 16, drives the universal joint fork 28 in its deflected state, causing the universal joint fork 28 to carry the rotating rod 29 to rotate. Then, the rotating rod 29... Rotation 9 causes the worm gear 30, which is fixedly mounted on the outer surface, to rotate. The worm gear 30 then engages with the gear 4 33 on the rotating rod 2 32, further causing the rotating rod 2 32 to rotate. When the rotating rod 2 32 rotates, it causes the gear 5 34 to rotate. The rotation of the gear 5 34 engages with the gear 6 35 on the rotating shaft 1 4, causing the rotating shaft 1 4 to rotate the take-up roller 5, thereby unfolding or rewinding the screen 6 wrapped around the outer surface of the take-up roller 5. Furthermore, the gear 6 35 on the rotating shaft 1 4 also engages with the gear 7 37 on the rotating rod 3 36, causing the rotating rod 3 36 to rotate the cleaning roller 38, which then rolls and cleans the screen 6, removing dust from the outer surface of the screen 6 and preventing the dust from affecting the projection effect.

[0029] Instructions for use: When projection teaching is required, first start motor 7, causing its output shaft 8 to drive the displacement transmission mechanism, which in turn pushes the support plate 3 to move. Simultaneously, the universal joint transmission mechanism is connected, causing the rewind roller to rotate and unfold the screen 6. When the support plate 3 moves to the center of the classroom, the screen 6 is fully unfolded, and the projection equipment is also fixedly connected to the support plate 3, moving synchronously with the support plate 3. When angle adjustment is needed to accommodate the viewing experience of students on both sides, start motor 18, causing its output shaft 20 to rotate with gear 21. This causes the support plate 3, carrying the screen 6, to deflect synchronously with the projection equipment, thus completing the angle deflection. When the teaching is over and the screen 6 needs to be rolled up, start motor 7, causing its output shaft 8 to reverse, which moves the support plate 3 to the left, to the corner of the classroom. At the same time, the aforementioned transmission mechanism reverses to roll up the screen 6, restoring it to its original state.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
