It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0019] refer to Figures 1 to 11A display device for higher education teaching includes a support plate 1, a vertical plate 2, a vertical mounting rod 3, a display plate 5, an extension plate 6, a handrail 11, rollers 8, a bottom display plate 14, a first sliding mechanism, a second sliding mechanism, a rotating mechanism, a retracting mechanism, and a lifting mechanism. Vertical plates 2 are vertically installed on the left and right side walls of the support plate 1. The first end of the vertical mounting rod 3 is vertically fixedly installed on the upper front part of the two vertical plates 2 respectively. The display plate 5 is rotatably installed between the second ends of the two vertical mounting rods 3. The display plate 5 is driven to rotate by a rotating mechanism. The support plate 1 and the two vertical plates 2 form a whole. The three are U-shaped. The two vertical mounting rods 3 are used to install the display plate 5. Two extension boards 6 are movably installed inside the display board 5. The two extension boards 6 are driven to slide by the retraction mechanism. When the display board 5 is perpendicular to the horizontal plane, it can be used as a vertical writing board, and teachers can write and display on the display board 5. When the display board 5 is gradually rotated to a horizontal state by the rotation mechanism, the two extension boards 6 inside will unfold to both sides, increasing the horizontal placement area. At this time, the display board 5 and the two protruding extension boards 6 are parallel to the horizontal plane, and several display items or experimental equipment can be placed on them for display. Display panel 5 operates by rotating to drive the unfolding mechanism; A bottom display board 14 is slidably installed between two vertical boards 2. The bottom display board 14 is movably installed above the support board 1. The bottom display board 14 is driven to slide by the first sliding mechanism. The bottom display board 14 is also used to place some teaching materials suitable for display, and can share the load of the two extension boards 6 and the display board 5. The rotating mechanism is driven by the first sliding mechanism. Two rollers 8 are movably installed on the outer side of the two vertical boards 2. All four rollers 8 are driven by a lifting mechanism. When the display board 5 is perpendicular to the horizontal plane, the rollers 8 will rise off the ground to increase the stability when writing on the board. When the display board 5 and the two extension boards 6 are parallel to the horizontal plane, the rollers 8 will descend under the action of the lifting mechanism and support the equipment, giving the equipment a certain degree of mobility and making it convenient to move and display in the classroom. The lifting mechanism is driven by the rotating mechanism. Handrails 11 are movably installed on the rear side of the two vertical plates 2 respectively. The two handrails 11 are driven to move by the second sliding mechanism. When the roller 8 contacts the ground and supports the equipment, the handrails 11 automatically extend to the rear side for easy support. When the roller 8 is lifted off the ground, they retract forward to reduce the footprint. The second sliding mechanism is driven by the lifting mechanism.
[0020] The first sliding mechanism includes a drive motor 13, a threaded rod 1301, a rectangular block 20, a first through slot 201, and a vertical movable plate 15; Two vertical plates 2 are respectively provided with first through slots 201, and the left and right side walls of the bottom display plate 14 are respectively slidably connected to the first through slots 201 that are close to them; A rectangular block 20 is installed at the lower end of the bottom display panel 14, and the rectangular block 20 is slidably installed at the upper end of the support plate 1; A drive motor 13 is installed at the upper rear of the support plate 1, and a threaded rod 1301 is fixedly installed on the output shaft of the drive motor 13. A threaded connection is provided between the threaded rod 1301 and the rectangular block 20; The first ends of vertical movable plates 15 are respectively vertically fixed to the rear of the left and right side walls of the bottom display panel 14 via the first fixed axis; Two vertical movable plates 15 are respectively movably installed on the outer side of the vertical plate 2 that is close to it; The two vertical movable plates 15 operate through a sliding drive rotation mechanism. By starting the drive motor 13, the output shaft of the drive motor 13 starts to rotate and drives the threaded rod 1301, which is fixed coaxially with it, to start rotating. During the rotation of the threaded rod 1301, the rectangular block 20, which is threaded through it, can start to slide on the support plate 1. The bottom display plate 14, which is fixedly installed on the upper end of the rectangular block 20, can slide synchronously with the rectangular block 20 at this time.
[0021] The rotating mechanism includes a first link 16 and a second link 17; The middle sections of the left and right side walls of the display panel 5 are respectively rotatably mounted between the second ends of the two vertical mounting rods 3 via one end of the second fixed shaft 12; The other ends of the two second fixed shafts 12 are respectively rotated through the second ends of the vertical mounting rods 3 that are close to them and the first ends of the first connecting rods 16 are fixedly installed thereon. The two first connecting rods 16 are respectively set perpendicularly to the display panel 5; The first end of the second connecting rod 17 is rotatably mounted on the inner wall of the second end of the two vertical movable plates 15; The second ends of the two second links 17 are respectively rotatably mounted on the inner wall of the second end of the first link 16 that is close to them; The two second links 17 respectively drive the lifting mechanism through deflection, see reference. Figure 10When the bottom display panel 14 slides to the right, the two vertical movable panels 15 fixed to it also begin to slide to the right simultaneously. During this sliding motion, the two vertical movable panels 15 respectively drive the two second connecting rods 17 to begin to deflect downwards. As the two second connecting rods 17 deflect downwards, they respectively drive the first connecting rods 16 adjacent to them to begin rotating downwards around their respective rotation centers. The display panel 5 fixed between the two first connecting rods 16 can then begin to rotate. Since the two first connecting rods 16 are perpendicular to the display panel 5, as... Figure 3 As shown, when the display panel 5 is perpendicular to the horizontal plane, the two first connecting rods 16 are parallel to the horizontal plane. When the two first connecting rods 16 rotate from a horizontal position to a position perpendicular to the horizontal plane, the display panel 5 can change from a state perpendicular to the horizontal plane to a state horizontal to the horizontal plane.
[0022] The retraction mechanism includes a first slider 601, a second through groove 502, a first through hole 602, a disc 4, an arc-shaped through groove 401, and a protruding post 19. Two discs 4 are fixedly installed on the inner walls of the second ends of the two vertical mounting rods 3 respectively. The display board 5 is rotatably installed between the two discs 4. Two second fixed shafts 12 are rotatably installed through the center of the discs 4 that are close to them. The display panel 5 has a first through hole 501 at its top and bottom ends, and the two expansion plates 6 are slidably connected to the first through hole 501 that are close to it. Two second through slots 502 are respectively provided on the left and right side walls of the display panel 5, and the two second through slots 502 are respectively installed on both sides of the second fixed shaft 12. The two second through slots 502 are respectively connected to the first through hole 501 adjacent to them; The left and right side walls of the two expansion plates 6 are respectively fixedly installed with first sliders 601, and the four first sliders 601 are respectively slidably connected to the second through slots 502 adjacent to them. The first ends of protrusions 19 are fixedly installed on the outer walls of the four first sliders 601 respectively; Each of the two discs 4 has two arc-shaped through slots 401, and the second ends of the four protruding pillars 19 are slidably connected to the adjacent arc-shaped through slots 401. (See reference) Figure 5When the display panel 5 rotates, it will drive the two expansion plates 6 to rotate. The first slider 601, which is fixedly installed with the two expansion plates 6, will also drive the protruding posts 19, which are fixedly installed with it, to rotate. Since the movement trajectory of the four protruding posts 19 is also limited within the arc-shaped through groove 401 that is close to them, and the four arc-shaped through grooves 401 are set on the two discs 4, which are fixed, when the display panel 5 is perpendicular to the horizontal plane, the two protruding posts 19 on the same side are close to each other and close to the center of the disc 4. When the display panel 5 rotates and gradually becomes parallel to the horizontal plane, the two protruding posts 19 on the same side begin to gradually separate along the arc-shaped through groove 401 that is close to them. When the display panel 5 rotates to be parallel to the horizontal plane, the two protruding posts 19 on the same side are just separated, and the line connecting the two is parallel to the horizontal plane. It should be noted that the arc-shaped through groove 401 is semi-circular to ensure that the protruding posts 19 can slide smoothly inside.
[0023] The lifting mechanism includes a horizontal lifting rod 7, a third through groove 1501, a second slider 20, and a third connecting rod 18; Two vertical movable plates 15 are respectively provided with third through grooves 1501, and second sliders 20 are slidably installed in the two third through grooves 1501. The middle ends of horizontal lifting rods 7 are fixedly installed on the outer walls of the two second sliders 20 through third fixed shafts 2001. Four rollers 8 are respectively mounted on the outer wall of the end of the horizontal lifting rod 7 that is close to it; The first end of the third connecting rod 18 is rotatably mounted on the inner wall of the two second sliders 20 via the fourth fixed shaft; The second ends of the two third links 18 are respectively rotatably mounted on the rear part of the inner wall of the second end of the adjacent second link 17; The two third fixed shafts 2001 respectively drive the second sliding mechanism. When the two second connecting rods 17 deflect, they will respectively drive the adjacent third connecting rods 18 to deflect. During the deflection process, the two third connecting rods 18 can respectively drive the adjacent second sliders 20 to slide up and down along the third through groove 1501. The horizontal lifting rod 7, which is fixedly installed with the two second sliders 20 through the third fixed shafts 2001, can then start to slide up and down and drive the two adjacent rollers 8 to move up and down respectively. (Reference) Figure 7 When the bottom display plate 14 drives the two vertical movable plates 15 to slide forward, the second slider 20 located in the two third through slots 1501 begins to slide upward, and the included angle between the second link 17 and the third link 18 begins to decrease. When the two vertical movable plates 15 slide backward, the two second sliders 20 begin to slide downward, and the included angle between the second link 17 and the third link 18 begins to increase.
[0024] The second sliding mechanism includes a horizontal fixed plate 9, a fourth through groove 902, a second through hole 901, a third slider 1001, a slide rod 10, and a fourth connecting rod 21; Two vertical movable plates 15 are respectively fixedly mounted on the outer walls of their second ends with horizontal fixed plates 9, and two third through slots 1501 are respectively installed below the horizontal fixed plates 9 that are close to them. The rear ends of the two horizontal fixed plates 9 are respectively provided with second through holes 901, and slide rods 10 are slidably installed in the two second through holes 901 respectively; Two handrails 11 are fixedly installed on the inner wall of the first end of the slide bar 10 that is close to them, and the two handrails 11 are movably installed on the rear side of the slide bar 10 that is close to them. The outer walls of the two horizontal fixed plates 9 are respectively provided with fourth through grooves 902, and the two fourth through grooves 902 are respectively connected to the second through hole 901 that is close to them. A third slider 1001 is fixedly installed on the outer wall of the second end of each of the two sliders 10. The two third sliders 1001 are slidably connected to the fourth through groove 902 that is close to them. The outer walls of the two third sliders 1001 are respectively fixedly installed with fifth fixed shafts, and the first ends of the fourth connecting rods 21 are respectively rotatably installed on the outer walls of the two fifth fixed shafts. The second ends of the two fourth links 21 are respectively rotatably mounted on the outer wall of the adjacent third fixed shaft 2001, for reference. Figure 9 At this point, the equipment is in a state where the display panel 5 is parallel to the horizontal plane. As the display panel 5 gradually rotates to a state perpendicular to the horizontal plane, the two horizontal lifting rods 7 gradually begin to rise. The third fixed shaft 2001, which is fixedly installed with it, then begins to move upward and gradually approaches the horizontal fixed plate 9 located above. During the upward movement of the two third fixed shafts 2001, they respectively drive the fourth connecting rods 21 on both sides to begin to deflect to the right. During the deflection to the right, the two fourth connecting rods 21 respectively drive the third slider 1001 that is close to them to move along the adjacent third slider 1001. Sliding to the left within the four-way slot 902, the slide rods 10, fixedly installed on the inner walls of the two third sliders 1001, begin to drive the adjacent handrails 11 to slide to the left. When the display panel 5 is completely perpendicular to the horizontal plane, the two slide rods 10 are completely retracted into the adjacent second through hole 901, achieving storage. When the two horizontal lifting rods 7 are lowered, the two slide rods 10 can then extend to the right from the second through hole 901. At this time, the rollers 8 contact the ground and support the equipment, and the handrails 11 extend out, allowing instructors to hold the two handrails 11 and push the equipment to move.
[0025] Implementation method of the present invention: In its initial state, the display board 5 is perpendicular to the horizontal plane, the two extension boards 6 are retracted inside the display board 5, the rollers 8 are raised off the ground, the slide bar 10 is retracted inside the horizontal fixed plate 9, and the support plate 1 supports the ground, increasing the stability of the equipment. Instructors can write and demonstrate on the front side of the display board 5 when the equipment is in this state. Figure 11 The state shown in A.
[0026] When the equipment needs to be displayed, the drive motor 13 is started, and the display panel 5 gradually rotates downward and becomes parallel to the horizontal plane. Two extension panels 6 gradually extend from both sides of the display panel 5, and the bottom display panel 14 gradually slides below the display panel 5. The four rollers 8 gradually lower and support the equipment. The two sliding rods 10 then drive the fixed handrails 11 to extend backward. When the display panel 5 is completely parallel to the horizontal plane, the bottom display panel 14 slides completely below the display panel 5, and the two extension panels 6 inside the display panel 5 extend to the front and rear sides and become parallel to the horizontal plane, just like the display panel 5. At this time, the equipment... Figure 11 In the state shown in B, the physical teaching aids or experimental equipment to be displayed can be placed on the display board 5, the two protruding extension boards 6, and the top of the bottom display board 14. By pushing the handle 11, the equipment can be moved in the classroom to expand the display range.
[0027] This invention provides a two-state display device for different individual exhibits in higher education. It can be transformed to suit different exhibits, allowing teachers to display them in the form of blackboard writing or place physical objects on the transformed display board and extension board. The combination of these two display methods can effectively increase students' memory and impression, and enhance teaching effectiveness.
