[0002] Graphic design broadly refers to a form of communication and expression that is both artistic and professional, using "visuals" as a means of communication and expression. It involves creating and combining symbols, images, and text in various ways to produce visual representations that convey ideas or messages. In graphic design education, the display of three-dimensional models is often included to help students understand the practical application of various design elements.

[0042] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] This invention provides a multifunctional auxiliary device for teaching graphic design.

[0044] Please refer to the following: Figure 1 and Figure 2In one embodiment of the present invention, a multifunctional auxiliary device for teaching graphic design includes: a lifting and rotating device 1;

[0045] The support platform 2 includes a central platform 21 and two rotating platforms 22. The two rotating platforms 22 are rotatably mounted on both sides of the central platform 21 via rotating shafts 23. The central platform 21 is mounted on the output end of the lifting and rotating device 1 via a pitch adjustment mechanism 5.

[0046] The lifting and rotating device 1 is used to lift the support platform 2 and drive the support platform 2 to rotate;

[0047] The extension positioning mechanism 3 is used to extend the two flipping tables 22 along both sides of the central platform 21 to keep them horizontal with the central platform 21, or to retract the two flipping tables 22 along both sides of the central platform 21 to keep them perpendicular to the central platform 21.

[0048] Two clamping mechanisms 4 are respectively installed on the two flipping tables 22.

[0049] By setting the support platform 2 to be retractable, when not in use, the flip platforms 22 on both sides of the central platform 21 can be rotated downwards by 90 degrees to be 90 degrees to the central platform 21, and then the lifting and rotating device 1 can be lowered to the lowest position, thereby greatly reducing the space occupied by the entire device and making it easier to store the entire auxiliary display device.

[0050] The center platform 21 has symmetrical extensions on both sides, and the rotating shaft 23 is installed between the two extensions on the same side.

[0051] Please see Figure 2 In this embodiment, the lifting and rotating device 1 includes a base 11, a mounting tube 12, a first motor 13, and a threaded rod 14. The mounting tube 12 is mounted on the top of the base 11. The first motor 13 is slidably mounted inside the mounting tube 12 via a sliding bracket 15. The bottom end of the threaded rod 14 is connected to the output shaft of the first motor 13. The threaded rod 14 is threadedly connected to the top end of the mounting tube 12. The pitch adjustment mechanism 5 is mounted on the top end of the threaded rod 14.

[0052] When the height of the support platform 2 needs to be adjusted, the first motor 13 rotates clockwise, driving the threaded rod 14 to rotate accordingly. The threaded rod 14 interacts with the threaded surface at the top of the inner surface of the mounting tube 12, moving upward along the mounting tube 12, while simultaneously driving the first motor 13 to move upward. The sliding frame 15 moves upward along the mounting tube 12, and the threaded rod 14 drives the support platform 2 to move upward. When not in use and retracted, the first motor 13 rotates in the opposite direction. Similarly, the threaded rod 14 descends along the mounting tube 12, thus completing the lifting function.

[0053] When it is necessary to rotate the support platform 2 to view the model from different angles during use, the first motor 13 rotates to a preset angle as needed, and the threaded rod 14 rotates to the same angle to adjust the angle of the support platform 2. That is, by using one motor to drive, the functions of lifting and rotating can be completed simultaneously.

[0054] Since the maximum adjustment angle during rotation adjustment is the same as the rotation of the support platform 2, and the height change is minimal when the threaded rod rotates one revolution, when the first motor 13 drives the threaded rod 14 to rotate to adjust the angle of the support platform 2, the support platform 2 will experience a slight height change, which will not affect the display of the model.

[0055] The inner wall of the mounting tube 12 is provided with strip-shaped sliding cavities on both sides. The sliding frame 15 includes a fixed hoop and two sliding blocks. The fixed hoop is installed on the first motor 13. The two sliding blocks are symmetrically arranged on both sides of the fixed hoop. The sliding blocks slide into the strip-shaped sliding cavity to realize the sliding key connection, thereby limiting the axial movement of the first motor 13 and enabling the first motor 13 to move stably up and down along the inside of the mounting tube 12.

[0056] The first motor 13 is a servo motor and has speed regulation function.

[0057] The top of the inner wall of the mounting tube 12 is provided with an internal thread surface, or a nut can be provided at the top of the mounting tube 12 to be threadedly connected to the threaded bar 14.

[0058] Of course, in other embodiments, the lifting and rotating device 1 can be provided with a lifting device and a rotating device respectively. The lifting device can be a cylinder, a hydraulic cylinder, a screw mechanism, etc., and the rotating device can be provided with a motor to adjust the horizontal angle of the support platform 2.

[0059] Please see Figure 3 , Figure 7 and Figure 8 In one embodiment, the extension positioning mechanism 3 includes a support sleeve 31, a V-shaped guide frame 33, two support blocks 32, mounting arms 34, and drive shafts 35. The support sleeve 31 is installed at the bottom of the center platform 21. The two support blocks 32 are symmetrically slidably disposed inside the support sleeve 31 at opposite ends, and the two support blocks 32 are respectively oriented towards the two flipping tables 22. The V-shaped guide frame 33 is installed on the mounting tube 12 via a connecting shaft. The top ends of the two mounting arms 34 are connected to the bottom ends of the two support blocks 32. The two drive shafts 35 are respectively installed at the bottom ends of the two mounting arms 34 and pass through both sides of the V-shaped guide frame 33.

[0060] When using this assistive device, please refer to Figure 7 Middle (7a) to (7b) and Figure 8 In the middle (81) to (8b), when the threaded bar 14 lifts the bearing platform 2, the center platform 21 drives the support sleeve 31 to lift, thereby driving the mounting arm 34 to move upward through the support block 32. The mounting arm 34 drives the drive shaft 35 to move upward. The drive shaft 35 moves along the corresponding V-shaped guide frame 33 to the side closer to the flipping platform 22. Thus, while the mounting arm 34 moves upward, it drives the support block 32 to extend towards the flipping platform 22. The support block 32 pushes the flipping platform 22 to unfold upward and unfold to be horizontal with the center platform 21, thereby realizing the unfolding of the flipping platform 22. The support block 32 supports the unfolded flipping platform 22 to keep it horizontal.

[0061] Please see Figure 7 In the middle, (7b) to (7c), when the threaded rod 14 continues to rise, the drive shaft 35 separates from the V-shaped guide frame 33. At this time, the height adjustment distance of the support platform 2 is L. It is adjusted to a suitable height according to the use needs. Each time the first motor 13 stops, it rotates an integer number of times, so that after each height adjustment, the support platform 2 stays in the initial orientation.

[0062] When not in use, when the threaded rod 14 descends and retracts, the drive shaft 35 re-enters the V-shaped guide frame 33, and through the mounting arm 34 drives the support block 32 to retract into the support sleeve 31 again. At this time, the support block 32 does not support the tilting table 22, and the tilting table 22 rotates down to be perpendicular to the center table 21 and parallel to the mounting tube 12.

[0063] The unfolding and adjustment of the tilting table 22 can be completed without manually adjusting its rotation and without setting up additional drive equipment.

[0064] Preferably, two sets of extension positioning mechanisms 3 are provided, located on both sides of the mounting tube 12;

[0065] The bottom of the support sleeve 31 has symmetrical slots. The top of the mounting arm 34 passes through the slots and connects to the corresponding support block 32. The opposite ends of the two support blocks 32 are preferably fitted with rubber sleeves. When the support block 32 extends out of the support sleeve 31, the friction between the end of the support block 32 inside the support sleeve 31 and the support sleeve 31 is increased, thereby improving stability.

[0066] In another embodiment, the extension positioning mechanism 3 may only be provided with a support sleeve 31 and a support block 32. After manually rotating the flip table 22, the support block 32 can be pulled out to support the flip table 22.

[0067] In another embodiment, multiple electric telescopic cylinders can be installed at the bottom of the central platform 21 to push the support block 32 to unfold and retract the tilting platform 22.

[0068] Please see Figure 4 and Figure 5The extension positioning mechanism 3 further includes a traction arm 36, which includes a connecting arm 361 and two piston blocks 362. The two piston blocks 362 are slidably disposed inside the support block 32. The two ends of the connecting arm 361 pass through the two support blocks 32 and are connected to the corresponding piston blocks 362.

[0069] By setting the traction arm 36, after the two support blocks 32 located in the same extension positioning mechanism 3 extend out of the support sleeve 31, the traction arm 36 can pull and limit the two support blocks 32, preventing the support blocks 32 from moving out of the support sleeve and improving the stability of the overall structure.

[0070] Please refer to it again. Figure 3 In this embodiment, the pitch adjustment mechanism 5 includes a second motor 51, a mounting shaft 52, and a mounting block 53. The mounting shaft 52 is mounted on the output end of the second motor 51, one end of the mounting block 53 is mounted on the mounting shaft 52, the second motor 51 is mounted on the top end of the threaded rod 14, and the center platform 21 is mounted on the top end of the mounting block 53.

[0071] By setting up a pitch adjustment mechanism 5, when different pitch angles are needed for observation, the second motor 51 drives the mounting shaft 52 to rotate by the corresponding angle, thereby causing the support platform 2 to rotate to the corresponding angle for easier observation. For example, when rotated 90 degrees, it allows students below the platform to view the model from the top.

[0072] The second motor 51 is a servo motor. The top of the threaded rod 14 is symmetrically provided with mounting ears. The mounting shaft 52 is rotatably mounted on the mounting ears, and the second motor 51 is mounted on one of the mounting ears.

[0073] In other embodiments, the pitch adjustment mechanism 5 may also be equipped with an electric telescopic cylinder. One end of the electric telescopic cylinder is rotatably mounted on the threaded rod 14, and the other end is rotatably connected to the bottom of the center platform 21. Meanwhile, the bottom of the center platform 21 is connected to the mounting shaft 52 through the mounting block 53, and the mounting shaft 52 is rotatably mounted on the top of the threaded rod 14.

[0074] Please see Figure 1 , Figure 4 and Figure 6In this embodiment, the clamping mechanism 4 includes a drive rod 41, a connecting plate 42, two mounting boxes 43, a rotating shaft 44, and a clamping plate 45. The drive rod 41 is rotatably mounted on the flipping table 22, the connecting plate 42 is slidably disposed on the flipping table 22, and the connecting plate 42 is threadedly connected to the drive rod 41. The two mounting boxes 43 are detachably mounted on both ends of the connecting plate 42. The clamping plate 45 is rotatably mounted on the mounting box 43 via the rotating shaft 44, and the rotation range of the clamping plate 45 along the rotating shaft 44 is ninety degrees.

[0075] When not in use, rotate the clamping plate 45 to be parallel to the flipping table 22 to reduce the space occupied when the auxiliary device is folded up. When in use, rotate the clamping plate 45 to be perpendicular to the flipping table 22. When clamping the model, place the model on the support platform 2, and then drive the clamping plate 45 located on the two flipping tables 22 to move to the opposite side by turning the drive rod 41 clockwise to clamp the model. When releasing, turn the drive rod 41 in the opposite direction to release the clamping plate 45.

[0076] When the clamping plate 45 rotates to be perpendicular to the flipping table 22, the clamping plate 45 rests against the rear wall of the mounting box 43, which limits the axial movement of the clamping plate 45. Thus, the clamping plate 45 can stably clamp the model. The surface of the rotating shaft 44 is preferably bonded with a rubber sleeve to increase the friction between it and the clamping plate 45. Without the action of external force, the clamping plate 45 will not rotate arbitrarily.

[0077] The clamping plate 45 is adjusted according to the shape of the model being clamped. When the model is a regular rectangle, the clamping plate 45 is L-shaped, and the four edges of the model are clamped by the four clamping plates 45. When the sides of the model are arc-shaped, the clamping plate 45 is set as an arc-shaped plate, so that it can fit the model better and the clamping is more stable.

[0078] The rotating table 22 has an installation groove, and the drive rod 41 is rotatably installed in the installation groove. Both ends of the drive rod 41 extend through the rotating table 22. The surface of the drive rod 41 is provided with external threads, and the bottom of the connecting plate 42 is threadedly connected to the drive rod 41 through a nut.

[0079] In one embodiment, a knob is provided at one end of the drive rod 41, which facilitates turning the drive rod 41.

[0080] In another embodiment, a drive motor is provided and connected to the drive rod 41 to automatically drive the drive rod 41 to rotate.

[0081] Please refer to it again. Figure 6In this embodiment, the clamping mechanism 4 further includes a gear frame 461 and a gear 462. The side of the gear 462 away from the tilting table 22 meshes with one end of the gear frame 461. The gear 462 is mounted on the rotating shaft 44. The other end of the gear frame 461 is detachably mounted on the tilting table 22.

[0082] Please refer to the following: Figure 9 In sections (9a) to (9b), by setting up the gear frame 461 and the gear 462, when in use, the drive rod 41 is turned and the connecting plate 42 moves a distance along the drive rod 41. At this time, the gear 462 acts with the gear frame 461, causing the clamping plate 45 to rotate ninety degrees and become perpendicular to the flipping table 22. When the connecting plate 42 moves again, the gear 462 separates from the gear frame 461 and will no longer adjust the angle of the clamping plate 45. When the connecting plate 42 needs to drive the clamping plate 45 to clamp the model, when it needs to be retracted, the drive rod 41 is turned in the opposite direction to the original position. At this time, the gear 462 acts with the gear frame 461 again, causing the clamping plate 45 to retract.

[0083] That is, the mechanism of using the drive rod 41 to adjust the clamping plate 45 to clamp the model can automatically adjust the unfolding and retraction of the clamping plate 45.

[0084] The gear frame 461 is a U-shaped frame, and the inner wall of the side of the U-shaped frame away from the tilting table 22 is provided with teeth. The teeth interact with the gear 462 to drive the gear 462 to rotate 90 degrees.

[0085] It can be understood that in other embodiments, a drive motor can also be provided, connected to the rotating shaft 44, to drive the rotating shaft 44 to rotate, thereby adjusting the clamping plate 45; or it can be adjusted manually.

[0086] Please see Figure 1 The tilting table 22 is provided with a sliding groove 221, and a slider is installed on the connecting plate 42, the slider sliding into the sliding groove 221.

[0087] By making the connecting plate 42 slidably connected to the tilting table 22, the connecting plate 42 can slide stably along the tilting table 22.

[0088] Please see Figure 1 The connecting plate 42 has multiple mounting holes, and the mounting box 43 is provided with an assembly shaft.

[0089] By opening multiple mounting holes on the connecting plate 42, the position of the mounting box 43 can be changed according to the size of the model to be clamped, thereby adjusting the position of the clamping plate 45;

[0090] In one embodiment, the mounting hole is a threaded hole, and the corresponding assembly shaft is a threaded shaft. The mounting box 43 is threadedly assembled with the threaded hole through the threaded shaft, and the clamping direction of the clamping plate 45 is towards the center platform 21 after each tightening.

[0091] In another embodiment, the mounting hole is a common insertion hole, and the mounting box 43 is inserted into the mounting hole through an assembly shaft. In this case, a rubber sleeve is fitted on the assembly shaft to increase the stability of the assembly with the mounting hole.

[0092] The installation method of the gear rack 461 and the center platform 21 is the same as the installation method of the mounting box 43 and the connecting plate 42.

[0093] Please see Figure 1 and Figure 3 A transmission rod 6 is rotatably connected to the central platform 21, and both ends of the transmission rod 6 pass through the central platform 21. Both ends of the transmission rod 6 are provided with assembly slots 61. One end of each of the two drive rods 41 is connected to an assembly block 411. When the two flipping tables 22 are unfolded along both sides of the central platform 21 to be horizontal with the central platform 21, the assembly block 411 is assembled with the assembly slot 61.

[0094] By setting the transmission rod 6, when the two flipping tables 22 are unfolded to be horizontal with the center table 21, the assembly blocks 411 at the ends of the drive rods 41 on the two flipping tables 22 are inserted into the assembly slots 61 at both ends of the transmission rod 6 to achieve assembly. Thus, when any drive rod 41 is rotated, the other drive rod 41 can be driven to rotate through the transmission rod 6, thereby simultaneously driving the clamping plates 45 on the two flipping tables 22 to move to the opposite side or the side away from each other, making the clamping operation more convenient.

[0095] The working principle of the multifunctional auxiliary device for graphic design teaching provided by this invention is as follows:

[0096] In use, the first motor 13 is started first (the control unit of the first motor 13 and the second motor 51 can be set on the central platform 21 or controlled by a remote control device); the first motor 13 drives the threaded cylinder 14 to rotate clockwise, which interacts with the mounting tube 12 and rises, thereby lifting the support platform 2 through the pitch adjustment mechanism 5.

[0097] Among them, the corresponding drive shaft 35 moves along the V-shaped guide frame 33, and drives the support block 32 to extend out of the support sleeve 31 through the mounting arm 34, pushing the two flip tables 22 to unfold and supporting the flip tables 22. At this time, the end assembly block 411 of the drive rod 41 is assembled with the assembly slots 61 at both ends of the transmission rod 6.

[0098] The first motor 13 stops when the support platform 2 is raised to a suitable height as needed.

[0099] Then, by turning the knob to turn the drive rod 41, the connecting plate 42 moves a distance, the gear 462 interacts with the gear frame 461, and drives the clamping plate 45 to rotate upward 90 degrees. At this time, the gear 462 separates from the gear frame 461, and the clamping plate 45 opens away from the rear wall of the mounting box 43, thus limiting the rotation of the clamping plate 45.

[0100] Then place the model in the middle of the support platform 2, and continue to rotate the drive rod 41 to drive the clamping plate 45 to clamp the model.

[0101] Subsequently, as needed, the first motor 13 drives the threaded rod 14 to rotate, thereby driving the support platform 2 to rotate, so as to adjust the angle of the model horizontally and display it from different angles;

[0102] And the second motor 51 can drive the mounting shaft 52 to rotate, thereby adjusting the pitch angle of the support platform 2 and displaying it from different pitch angles;

[0103] After the demonstration is completed, the clamping plate 45 can be retracted in sequence, and then the first motor 13 rotates in the opposite direction. The threaded rod 14 is retracted into the interior of the mounting tube 12, and the drive shaft 35 moves along the V-shaped guide frame 33 again. The support block 32 is retracted through the mounting arm 34, and the tilting table 22 rotates downwards again to retract, thereby greatly reducing the space occupied by the entire auxiliary equipment, making it easy to store and operate.

[0104] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.

The lifting and rotating device is used to lift the support platform and drive the support platform to rotate. An extension positioning mechanism is provided for extending the two flipping tables along both sides of the central platform until they are horizontal with the central platform, or retracting the two flipping tables along both sides of the central platform until they are perpendicular to the central platform. Two clamping mechanisms are respectively installed on the two flip tables; The extension positioning mechanism includes a support sleeve, a V-shaped guide frame, two support blocks, mounting arms, and drive shafts. The support sleeve is installed at the bottom of the central platform. The two support blocks are symmetrically slidably disposed inside the support sleeve at opposite ends, with their disjointed ends facing the two flipping platforms respectively. The V-shaped guide frame is installed in the mounting tube of the lifting and rotating device via a connecting shaft. The top ends of the two mounting arms are connected to the bottom ends of the two support blocks respectively. The two drive shafts are installed at the bottom ends of the two mounting arms respectively, and the two drive shafts pass through both sides of the V-shaped guide frame. The clamping mechanism includes a drive rod, a connecting plate, two mounting boxes, a rotating shaft, and a clamping plate. The drive rod is rotatably mounted on the flipping table, the connecting plate is slidably disposed on the flipping table, and the connecting plate is threadedly connected to the drive rod. The two mounting boxes are detachably mounted on both ends of the connecting plate. The clamping plate is rotatably mounted on the mounting box via the rotating shaft, and the clamping plate rotates within a range of ninety degrees along the rotating shaft. A transmission rod is rotatably connected to the central platform, and both ends of the transmission rod pass through the central platform. Both ends of the transmission rod are provided with assembly slots. One end of each of the two drive rods is connected to an assembly block. When the two flipping tables are unfolded along both sides of the central platform to be horizontal with the central platform, the assembly block is assembled with the assembly slot. The lifting and rotating device includes a base, a mounting tube, a first motor, and a threaded rod. The mounting tube is installed on the top of the base. The first motor is slidably installed inside the mounting tube via a sliding bracket. The bottom end of the threaded rod is connected to the output shaft of the first motor. The threaded rod is threadedly connected to the top end of the mounting tube. The pitch adjustment mechanism is installed on the top end of the threaded rod. The pitch adjustment mechanism includes a second motor, a mounting shaft, and a mounting block. The mounting shaft is mounted on the output end of the second motor, one end of the mounting block is mounted on the mounting shaft, the second motor is mounted on the top end of the threaded rod, and the center platform is mounted on the top end of the mounting block. The clamping mechanism further includes a gear frame and a gear. The side of the gear away from the tilting table meshes with one end of the gear frame. The gear is mounted on the rotating shaft, and the other end of the gear frame is detachably mounted on the tilting table. In use, the first motor is started first; the first motor drives the threaded rod to rotate clockwise, which interacts with the mounting tube and rises, thereby raising the support platform through the pitch adjustment mechanism. The corresponding drive shaft moves along the V-shaped guide frame, and the mounting arm drives the support block to extend out of the support sleeve, pushing the two flip tables to unfold and supporting the flip tables. At this time, the end assembly block of the drive rod is assembled with the assembly slots at both ends of the transmission rod. The first motor stops when the platform is raised to a suitable height as needed. Then, by turning the knob on the drive rod, the connecting plate moves a certain distance. The gear interacts with the gear frame, causing the clamping plate to rotate upward by 90 degrees. At this time, the gear separates from the gear frame, and the clamping plate moves away from the rear wall of the mounting box, thus limiting the rotation of the clamping plate. Then the model is placed in the middle of the support platform, and the drive rod is rotated to drive the clamping plate to clamp the model. Subsequently, as needed, the first motor drives the threaded rod to rotate, thereby driving the support platform to rotate, realizing the horizontal adjustment of the model's angle, and thus displaying it from different angles; And by driving the mounting shaft to rotate via the second motor, the pitch angle of the support platform can be adjusted, allowing for display from different pitch angles; After the demonstration is completed, the clamping plates are retracted one by one, then the first motor rotates in the opposite direction, the threaded rod is retracted into the interior of the mounting tube, and the drive shaft moves along the V-shaped guide frame again, driving the support block to retract through the mounting arm. The flipping table then rotates downwards to retract, thereby greatly reducing the space occupied by the entire auxiliary equipment, making it easy to store and operate.
