Description

Technical Field

[0001] This utility model relates to the field of teaching all-in-one machine technology, specifically a teaching all-in-one machine with physical display function. Background Technology

[0002] The interactive whiteboard can not only display computer screen content and play videos like a traditional projector, but it can also work with a camera to capture and magnify real objects in real time and project the images onto the interactive whiteboard for display, so as to facilitate detailed demonstrations and explanations in the classroom.

[0003] Interactive educational displays typically have wheels on their bottom for easy movement to any location. However, to prevent accidental movement by onlookers during demonstrations, these wheels are usually locked. Existing locking methods involve installing brake pads on each wheel, but this is cumbersome due to the large number of wheels and the need for users to manually operate each brake pad sequentially. Therefore, this paper proposes an interactive educational display with a physical demonstration function to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a teaching all-in-one machine with a physical display function, which has the advantages of simple operation and solves the problem that the operation process is cumbersome because there are many wheels and users need to operate the brake pads of each wheel in turn.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a teaching all-in-one machine with physical display function, comprising:

[0006] The stand has a main body of the interactive whiteboard fixed on it. The side of the stand is equipped with a physical camera that is connected to the main body of the interactive whiteboard and a physical object placement board that corresponds to the physical camera and can be flipped and stored. By placing the physical object on the physical object placement board, the physical camera takes a picture of the physical object and projects the picture onto the main body of the interactive whiteboard for display.

[0007] A pair of U-shaped fixing plates are fixed to the bottom of the bracket. Each U-shaped fixing plate has a pair of rotatable wheel support frames rotatably mounted via a support tube. A rotatable wheel is mounted within each rotatable wheel support frame. The bracket also has a stop rod with one end passing through the support tube and the rotatable wheel support frame and capable of abutting against the rotatable wheel. By driving the stop rod downwards, the bottom end of the stop rod abuts against the rotatable wheel, thus keeping the rotatable wheel stationary and improving the stability of the entire device.

[0008] Furthermore, a fixing sleeve is fixed to the bracket, a rotating sleeve is rotatably mounted at the bottom end of the fixing sleeve, a connecting rod is fixed to the side of the rotating sleeve, a fixing block is rotatably mounted at the end of the connecting rod, and the end of the object placement plate is fixed to the fixing block. The object placement plate can be flipped around the connecting rod so that its supporting surface faces forward, and then flipped around the fixing sleeve so that its supporting surface faces backward, allowing the object placement plate to be stored behind the main body of the interactive teaching machine.

[0009] Furthermore, a support rod is hinged to the bottom of the object placement plate, and a threaded rod is threaded to the end of the support rod. A support head is fixed to the end of the threaded rod, and an abutment block is fixed to the corresponding position of the bracket. A fixing clamp that mates with the support rod is fixed to the bottom surface of the object placement plate. The support rod can provide stable support for the object placement plate, improving its stability. When it needs to be stored, the threaded rod can be turned so that the support head is no longer in contact with the abutment block. Then, the support rod can be rotated counterclockwise until its end is engaged in the fixing clamp. At this time, the support rod is parallel and restricted to the bottom surface of the object placement plate, and can rotate with the object placement plate to the rear of the teaching all-in-one machine.

[0010] Furthermore, the support tube is open at both ends, and each end is rotatably mounted on a U-shaped fixed plate and a movable wheel support frame via bearings. The movable wheels can change direction at will, making it easier to move.

[0011] Furthermore, a horizontal plate is fixed to the top surface of the two abutment rods on the same side. A return spring is sleeved on the outer periphery of the abutment rod between the horizontal plate and the bracket. A metal chamber is fixed on the bracket. A pair of L-shaped flipping rods are hinged to the inner top wall of the metal chamber. The horizontal ends of the L-shaped flipping rods abut against the horizontal plate. Two connecting pipes are fixed to the top of the metal chamber. A linkage chamber fixed to the bracket is fixed to the top end of the two connecting pipes. A pair of take-up rollers are rotatably installed inside the linkage chamber. A pull rope is wound around the outer shaft of the take-up rollers. The end of the pull rope passes through the connecting pipe and is fixed to the bottom of the vertical end of the L-shaped flipping rod. By releasing or winding the pull rope through the pair of take-up rollers, multiple abutment rods move up and down together.

[0012] Furthermore, the linkage chamber is also equipped with a rotary drive unit that drives a pair of take-up rollers to simultaneously wind or release the pull rope. The rotary drive unit can drive a pair of take-up rollers to simultaneously wind or release the pull rope.

[0013] Furthermore, the rotary drive component includes multiple rotating shafts, in even numbers, rotatably mounted within the linkage chamber via bearings. Two take-up rollers are respectively fixed to the outer circumference of the two outer rotating shafts. A transition gear is fixed to the outer side of each rotating shaft, and adjacent transition gears mesh with each other. The transition gears allow multiple rotating shafts to rotate simultaneously, with the inner rotating shafts of a pair of take-up rollers rotating in opposite directions.

[0014] Furthermore, a worm gear is fixed to the outer side of any one of the rotating shafts, and a worm is rotatably mounted at the bottom of the linkage chamber via a bearing, with one end penetrating and extending into the linkage chamber and meshing with the worm gear. The worm can drive the worm gear to rotate, causing the corresponding rotating shaft to rotate.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This interactive teaching machine with physical demonstration function drives a pair of take-up rollers to simultaneously wind up the pull ropes through the meshing transmission of the transition gears via a rotating worm gear. The ends of the two pull ropes can then simultaneously drive the vertical ends of a pair of L-shaped flipping rods to flip relative to each other. At this time, the horizontal ends of the L-shaped flipping rods can press down on the horizontal plate, causing the horizontal plate to drive the abutment rod to move downwards until the abutment rod passes through the support tube and the moving wheel support frame and abuts against the moving wheels. This can restrict multiple moving wheels to remain stationary without the need to operate all moving wheels sequentially, making operation simpler and more convenient.

[0017] 2. This interactive teaching machine with physical display function, such as... Figure 2 In the indicated state, tighten the threaded rod so that the support head no longer abuts against the abutment block. Then rotate the support rod counterclockwise until its end is inserted into the fixing pipe clamp. At this time, the support rod is parallel and restricted to the bottom surface of the object placement plate. Then flip the object placement plate with the connecting rod as the center so that its supporting surface faces forward. Finally, flip the object placement plate with the fixing sleeve as the center so that its supporting surface faces backward. At this time, the object placement plate is parallel to the main body of the teaching interactive whiteboard and located on the rear side of the main body of the teaching interactive whiteboard, thus forming a storage state that does not take up too much space or affect use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The teaching all-in-one machine with physical display function in this embodiment includes a bracket 1, a teaching all-in-one machine body 2 fixed on the bracket 1, a physical camera 3 connected to the teaching all-in-one machine body 2 and a physical placement board 4 corresponding to the physical camera 3 and capable of being flipped and stored on the side of the bracket 1.

[0026] By placing the physical object on the physical object placement board 4, the physical object camera 3 takes a picture of the physical object and projects the picture onto the main body 2 of the teaching all-in-one machine for display.

[0027] The storage board 4 can be flipped up for storage, thus saving space. As a preferred embodiment, such as... Figure 1-2 As shown, specifically, a fixing sleeve 5 is fixed to the longitudinal support rod of the bracket 1 by bolts. A rotating sleeve 6 is rotatably mounted on the bottom end of the fixing sleeve 5 via a bearing. A connecting rod 7 is fixed to the side of the rotating sleeve 6. A fixing block 8 is rotatably mounted on the end of the connecting rod 7 via a bearing. The end of the object placement plate 4 is fixed to the fixing block 8 by bolts. A support rod 9 is hinged to the bottom of the object placement plate 4. A threaded rod 10 is threaded to the end of the support rod 9. A support head 11 is fixed to the end of the threaded rod 10. An abutment block 12 is fixed at a corresponding position on the longitudinal support rod of the bracket 1. A fixing pipe clamp 13 is fixed to the bottom surface of the object placement plate 4.

[0028] Under normal use, the display board 4 is in the unfolded state, and physical objects can be placed on the display board 4 for display. When the display board 4 is not needed, such as... Figure 2In the indicated state, screw the threaded rod 10, and the threaded rod 10 retracts into the support rod 9, so that the support head 11 no longer abuts against the abutment block 12. Then rotate the support rod 9 counterclockwise until its end is inserted into the fixing tube clamp 13. At this time, the support rod 9 is parallel and restricted to the bottom surface of the object placement plate 4. Since the fixing block 8 and the connecting rod 7 are rotatably connected by the bearing, the object placement plate 4 is then flipped around the connecting rod 7 so that its supporting surface faces forward. Since the rotating sleeve 6 and the fixing sleeve 5 are rotatably connected by the bearing, the object placement plate 4 is finally flipped around the fixing sleeve 5 so that its supporting surface faces backward. At this time, the object placement plate 4 is parallel to the main body 2 of the teaching all-in-one machine and is located on the rear side of the main body 2 of the teaching all-in-one machine, thus forming a storage state that does not occupy too much space or affect use.

[0029] In this embodiment, as Figure 1 , Figure 3-5 As shown, a pair of U-shaped fixing plates 14 are fixed at the bottom of the bracket 1. A pair of movable wheel support frames 16 are rotatably provided in each U-shaped fixing plate 14 through the support tube 15. Movable wheels 17 are rotatably provided in the movable wheel support frames 16. The bracket 1 is also provided with multiple abutment rods 18, one end of which passes through the support tube 15 and the movable wheel support frame 16 and can abut against the movable wheel 17.

[0030] By driving the abutment rod 18 downward, the bottom end of the abutment rod 18 abuts against the moving wheel 17, which can keep the moving wheel 17 stationary and improve the stability of the entire device.

[0031] The support tube 15 has open ends at both the top and bottom, and the two ends are respectively rotatably mounted in the U-shaped fixed plate 14 and the moving wheel support frame 16 through bearings. The moving wheel 17 can change direction at will, making it easier to move.

[0032] As for how to drive the abutment rod 18 downward, as a preferred embodiment, such as Figure 4-5 As shown, a horizontal plate 19 is fixed to the top surface of two abutment rods 18 on the same side. A return spring 20 is sleeved on the outer periphery of the abutment rods 18 between the horizontal plate 19 and the bracket 1. A metal chamber 21 is fixed on the bracket 1. A pair of L-shaped flip rods 22 are hinged to the inner top wall of the metal chamber 21. The horizontal end of the L-shaped flip rod 22 abuts against the horizontal plate 19. Two connecting pipes 23 are fixed to the top of the metal chamber 21. A linkage chamber 24 fixed to the bracket 1 is fixed to the top end of the two connecting pipes 23. A pair of take-up rollers 25 are rotatably arranged in the linkage chamber 24. A pull rope 26 is wound around the outer shaft of the take-up rollers 25. The end of the pull rope 26 passes through the connecting pipe 23 and is fixed to the bottom of the vertical end of the L-shaped flip rod 22. A rotary drive is also provided in the linkage chamber 24 to drive the pair of take-up rollers 25 to simultaneously take up or release the pull rope 26.

[0033] A pair of take-up rollers 25 simultaneously take up the pull ropes 26. The ends of the two pull ropes 26 simultaneously drive the vertical ends of a pair of L-shaped flipping rods 22 to flip relative to each other. At this time, the horizontal ends of the L-shaped flipping rods 22 can press down on the horizontal plate 19, the return spring 20 is compressed, and the horizontal plate 19 can drive the abutment rod 18 to move downward until the abutment rod 18 passes through the support tube 15 and the moving wheel support frame 16 and abuts against the moving wheel 17, thus restricting the moving wheel 17 to remain stationary.

[0034] When the device needs to be moved using the moving wheels 17, a pair of take-up rollers 25 simultaneously release the pull ropes 26. The ends of the two pull ropes 26 no longer exert tension on the pair of L-shaped flipping rods 22. At this time, the tension generated by the squeezed return spring 20 can reset the horizontal plate 19, and the abutment rod 18 moves upward and no longer abuts against the moving wheels 17, so the device can be moved normally using the moving wheels 17.

[0035] As a specific structure of a rotary drive component, such as Figure 5 As shown, the rotary drive includes multiple rotating shafts 27, which are rotatably mounted in the linkage chamber 24 via bearings and are in even numbers. Two take-up rollers 25 are respectively fixed to the outer periphery of the two outer rotating shafts 27. A transition gear 28 is fixed to the outer side of each rotating shaft 27, and adjacent transition gears 28 mesh with each other. A worm gear 29 is fixed to the outer side of any rotating shaft 27. A worm 30 is rotatably mounted at the bottom of the linkage chamber 24 via bearings, with one end penetrating through and extending into the linkage chamber 24 and meshing with the worm gear 29.

[0036] By rotating the worm 30, the worm wheel 29 drives the meshing worm wheel 29 to rotate, which in turn rotates the corresponding shaft 27. The transition gear 28 on the outside of the shaft 27 can then rotate. Under the meshing action of the adjacent transition gears 28, all shafts 27 can rotate, causing the two take-up rollers 25 to rotate simultaneously in opposite directions, thus allowing the rope 26 to be wound or released at the same time.

[0037] In summary, during normal use, the object placement plate 4 is in an unfolded state, allowing objects to be placed on it. The object camera 3 captures images of the objects and projects these images onto the main body 2 of the interactive whiteboard for display. When object display is not required, such as... Figure 2 In the indicated state, tighten the threaded rod 10 so that the support head 11 no longer abuts against the abutment block 12. Then rotate the support rod 9 counterclockwise until its end is inserted into the fixing tube clamp 13. At this time, the support rod 9 is parallel and restricted to the bottom surface of the object placement plate 4. Then flip the object placement plate 4 with the connecting rod 7 as the center so that its supporting surface faces forward. Finally, flip the object placement plate 4 with the fixing sleeve 5 as the center so that its supporting surface faces backward. At this time, the object placement plate 4 is parallel to the teaching all-in-one machine body 2 and is located on the rear side of the teaching all-in-one machine body 2, completing the rotation and storage of the object placement plate 4.

[0038] When it is necessary to lock the movable wheel 17 so that the entire device cannot move, by rotating the worm gear 30, the worm wheel 29 drives the meshing worm wheel 29 to rotate, which in turn rotates the corresponding rotating shaft 27. The transition gear 28 on the outside of the rotating shaft 27 can then rotate. Under the meshing action of the adjacent transition gears 28, all rotating shafts 27 can rotate, causing the two take-up rollers 25 to rotate simultaneously, thereby winding up the pull rope 26. The ends of the two pull ropes 26 can simultaneously drive the vertical ends of a pair of L-shaped flipping rods 22 to flip relative to each other. At this time, the horizontal ends of the L-shaped flipping rods 22 can press down on the horizontal plate 19, the return spring 20 is compressed, and the horizontal plate 19 can drive the abutment rod 18 to move downward until the abutment rod 18 passes through the support tube 15 and the movable wheel support frame 16 and abuts against the movable wheel 17, thus restricting the movable wheel 17 to remain stationary.

[0039] When the device needs to be moved using the moving wheel 17, the worm 30 is rotated in the opposite direction. Under the transmission action of the worm wheel 29, the worm 30, and the transition gear 28, a pair of take-up rollers 25 rotate and simultaneously release the pull ropes 26. The ends of the two pull ropes 26 no longer exert tension on a pair of L-shaped flipping rods 22. At this time, the tension generated by the squeezed return spring 20 can reset the horizontal plate 19, and the abutment rod 18 moves upward and no longer abuts against the moving wheel 17. The device can then be moved normally using the moving wheel 17.
