Description

Technical Field

[0001] This utility model relates to the field of cultural tourism exhibition technology, and in particular to a physical interactive newspaper viewing and display device. Background Technology

[0002] In the cultural heritage industry, existing devices are mainly divided into four categories: screenless mechanical devices, touch screen interactive devices, cultural relic-grade printing presses, and modern digital reading devices, but all of them have systemic defects.

[0003] Traditional scrolling light boxes and rotating advertising pages use basic mechanical transmission designs, which can automatically turn pages, but lack interactivity. While capacitive touch screens and projection page-turning devices can simulate newspaper reading through virtual animation, their interaction is limited and purely virtual, lacking realism and reducing the cultural appeal of the exhibits. Using mechanical printing presses as static exhibits lacks the ability to dynamically generate personalized content based on user operations, making it difficult to meet the comprehensive requirements of high reliability, strong interactivity, and immersive experience. Utility Model Content

[0004] The main purpose of this invention is to propose a physical interactive newspaper reading and display device to improve the interactivity and display effect of the device.

[0005] To achieve the above objectives, the present invention proposes a physical interactive newspaper viewing and display device, comprising:

[0006] A support frame, comprising two uprights, with a roller assembly positioned between the two uprights;

[0007] The demonstration paper is fitted onto the outside of the two rollers of the roller assembly. The demonstration paper rotates with the rotation of the rollers. The rollers are connected to a motor, which is fixedly connected to the upright frame to drive the rollers to rotate.

[0008] The display screen is mounted between the two stands and is located outside the presentation paper;

[0009] The control component includes a rotating component and a detection component. The rotating component is rotatably connected to the upright frame, and the detection component is used to detect the rotation of the rotating component. The detection component is electrically connected to the motor and the display screen. When the rotating component rotates, the motor drives the roller to rotate according to the rotation of the rotating component, and the display screen displays the rotation of the rotating component.

[0010] In one embodiment, the roller is rotatably connected to the upright frame via a first rotating shaft at both ends. The roller assembly includes a driving roller and a driven roller. The driving roller is connected to the output end of the motor via a transmission component to drive the driving roller to rotate.

[0011] The demonstration paper is fitted onto the outside of the driving roller and the driven roller. The rotation of the driving roller drives the demonstration paper to rotate, and the demonstration paper in turn drives the driven roller to rotate.

[0012] In one embodiment, a first transmission gear is fixedly sleeved on the first rotating shaft of the drive roller, and a second transmission gear is sleeved on the output end of the motor. The first transmission gear and the second transmission gear mesh to drive the drive roller to rotate.

[0013] Both the first transmission gear and the second transmission gear are helical gears.

[0014] In one embodiment, an image recognition component is fixedly connected to the side of the display screen near the presentation paper. The image recognition component is used to scan the presentation paper to determine its position. The image recognition component is electrically connected to the motor to drive the drive roller to rotate according to the position of the presentation paper.

[0015] In one embodiment, the physical interactive newspaper viewing and display device further includes a tensioning component, which includes a tensioning rod and a first rotating wheel. The first rotating wheel is rotatably connected to the outside of the stand, and the tensioning rod is fixedly connected to the first rotating wheel and rotates around the axis of the first rotating wheel. The surface of the tensioning rod abuts against the demonstration paper. The rotation of the first rotating wheel drives the tensioning rod to move, so as to adjust the tension force of the tensioning rod on the demonstration paper.

[0016] In one embodiment, the tensioning assembly further includes a connecting rod, one end of which is fixedly connected to the first rotating wheel, and the connecting rod is arranged radially along the first rotating wheel, with the end of the connecting rod away from the first rotating wheel fixedly connected to the tensioning rod;

[0017] The stand has an arc-shaped window, and the tensioning rod passes through the arc-shaped window to abut against the demonstration paper.

[0018] In one embodiment, the tensioning assembly further includes a second rotating wheel, which is rotatably connected to the outside of the upright, the diameter of the second rotating wheel is larger than the diameter of the first rotating wheel, and the second rotating wheel and the first rotating wheel are engaged.

[0019] The second roller is equipped with a fastener, which increases the friction between the second roller and the upright to achieve relative fixation between the second roller and the upright.

[0020] In one embodiment, a limiting groove is formed on one side of the first rotating wheel near the upright. A first elastic member and a first abutting member are provided in the groove. One end of the first elastic member is connected to the bottom of the limiting groove, and the other end is connected to the first abutting member. The first abutting member abuts against the outer side of the upright, and the first elastic member is in a compressed state.

[0021] In one embodiment, the presentation paper includes a first paper side closer to the display screen and a second paper side farther from the display screen;

[0022] The number of tensioning components is four, which are located on the uprights on both sides. The tensioning rods of the four tensioning components abut against the inner side of the first paper surface, and the four tensioning rods are located at the four corners of the first paper surface.

[0023] In one embodiment, the rotating component is a handwheel, which is rotatably connected to the upright frame. The detection component is a rotary encoder, which is located at the end of the second rotating shaft of the handwheel and connected to the second rotating shaft, for detecting the rotation of the handwheel. The rotary encoder is electrically connected to the motor and the display screen.

[0024] The technical solution of this utility model uses the linkage between the rotating component and the detection component to convert the user's physical operation into an electronic control signal in real time, synchronously driving the mechanical movement of the roller to update the multimedia content of the presentation paper and the display screen. This solves the problem of the disconnect between the action of traditional mechanical devices and digital content. Furthermore, the display screen and the presentation paper are set up in correspondence, and the spatial layout creates a parallax enhancement effect. As the presentation paper flips and changes, the content on the display screen changes synchronously to enhance interactivity and improve immersion. In addition, the presentation paper can be controlled by the rotating component, enhancing the realism and immersion of the audience's operation. Attached Figure Description

[0037] In the cultural heritage industry, existing devices are mainly divided into four categories: screenless mechanical devices, touch screen interactive devices, cultural relic-grade printing presses, and modern digital reading devices, but all of them have systemic defects.

[0038] Traditional scrolling light boxes and rotating advertising pages use basic mechanical transmission designs, which can automatically turn pages, but lack interactivity. While capacitive touch screens and projection page-turning devices can simulate newspaper reading through virtual animation, their interaction is limited in scope. Purely virtual interaction lacks realism and reduces the cultural appeal of the exhibits. When using mechanical printing presses as static exhibits, they lack the ability to dynamically generate personalized content based on user operations, making it difficult to meet the comprehensive requirements of high reliability, strong interactivity, and immersive experience.

[0039] This utility model proposes a physical interactive newspaper viewing and display device 100.

[0040] Please see Figures 1 to 4 In one embodiment of this utility model, the physical interactive newspaper reading and display device 100 includes:

[0041] Support frame 1, the support frame 1 includes two uprights 11, and a roller assembly 2 is mounted between the two uprights 11;

[0042] The demonstration paper 3 is fitted onto the outside of the two rollers of the roller assembly 2. The demonstration paper 3 rotates with the rotation of the rollers. The rollers are connected to a motor 4, which is fixedly connected to the stand 11 to drive the rollers to rotate.

[0043] Display screen 5 is mounted between the two supports 11 and located outside the presentation paper 3;

[0044] The control component includes a rotating component 61 and a detection component. The rotating component 61 is rotatably connected to the support frame 11. The detection component is used to detect the rotation of the rotating component 61. The detection component is electrically connected to the motor 4 and the display screen 5. When the rotating component 61 rotates, the motor 4 drives the roller to rotate according to the rotation of the rotating component 61, and the display screen 5 displays the rotation of the rotating component.

[0045] It should be noted that the physical interactive newspaper reading and display device 100 also includes a processor. The display screen 5, the motor 4, and the detection element are all electrically connected to the processor. The processor identifies and processes the information collected by the detection element and controls the rotation speed and direction of the motor 4 accordingly, thereby controlling the display screen 5 to modify the displayed content.

[0046] It should be noted that, for ease of explanation and understanding, the following description is based on the direction in which the support frame 1 contacts the ground. This is only for the purpose of aiding understanding and is not intended to impose further limitations.

[0047] Understandably, for example, when the user rotates the rotating component 61 clockwise, the content displayed on the display screen 5 moves upward, and at the same time, the motor 4 drives the roller to rotate, and the roller drives the presentation paper 3 to rotate. The portion of the presentation paper 3 near the user moves upward synchronously with the content displayed on the display screen 5 for display.

[0048] Among them, motor 4 is a servo motor to achieve precise motion control.

[0049] The technical solution of this utility model uses the linkage between the rotating component 61 and the detection component to convert the user's physical operation into an electronic control signal in real time, synchronously driving the mechanical movement of the roller to update the multimedia content of the presentation paper 3 and the display screen 5. This solves the problem of the disconnect between the action of traditional mechanical devices and digital content. Furthermore, the display screen 5 and the presentation paper 3 are set up in correspondence, and the spatial layout creates a parallax enhancement effect. As the presentation paper 3 flips and changes, the content of the display screen 5 changes synchronously to enhance interactivity and improve immersion. Moreover, the presentation paper 3 can be controlled by the rotating component 61, enhancing the realism and immersion of the audience's operation.

[0050] like Figure 1 As shown, it should be noted that the support frame 1 also includes a crossbeam 12, with two uprights 11 connected to both ends of the crossbeam 12 to fix the two uprights 11 and improve the overall stability of the support frame 1.

[0051] Furthermore, the two ends of the crossbeam 12 are detachably connected to the upright frame 11. Due to the needs of cultural and tourism display, the device may need to be displayed in different places. Through the detachable connection between the crossbeam 12 and the upright frame 11, the crossbeam 12 can be removed during transportation, and the upright frame 11 and the crossbeam 12 can be stacked, reducing the space occupation rate and facilitating transportation.

[0052] In one embodiment, the crossbeam 12 and the upright 11 are connected by flanges and bolts. The end of the crossbeam 12 is welded with an annular flange, and the upright 11 is provided with a corresponding flange. The two are fixed by bolts, and the connection and separation of the upright 11 and the crossbeam 12 are achieved by removing the bolts.

[0053] In another embodiment, the crossbeam 12 and the upright 11 are connected by a positioning pin, and the connection and separation of the upright 11 and the crossbeam 12 are achieved by installing and removing the positioning pin.

[0054] Optionally, the roller is rotatably connected to the upright frame 11 via a first rotating shaft 211 provided at both ends. The roller assembly 2 includes a driving roller 21 and a driven roller 22. The driving roller 21 is connected to the output end of the motor 4 via a transmission component to drive the driving roller 21 to rotate.

[0055] The demonstration paper 3 is sleeved on the outside of the driving roller 21 and the driven roller 22. The rotation of the driving roller 21 drives the demonstration paper 3 to rotate, and the demonstration paper 3 drives the driven roller 22 to rotate.

[0056] like Figure 2 As shown, it should be noted that the driving roller 21 serves as the driving force source, while the driven roller 22 provides auxiliary support and tension adjustment.

[0057] It is understandable that the driven roller 22 is driven to rotate by the friction generated by the adhesion between the demonstration paper 3 and the driven roller 22. When the driving roller 21 starts to rotate, the driven roller 22 does not start to rotate. Due to the difference in rotation speed between the driving roller 21 and the driven roller 22, the tension of the demonstration paper 3 will be increased to ensure the flatness of the paper surface.

[0058] It should be noted that in some embodiments, both the driving roller 21 and the driven roller 22 are equipped with motors, and the two motors rotate synchronously to achieve control.

[0059] In some embodiments, the driving roller 21 and the driven roller 22 are connected by gears or a timing belt to achieve synchronous rotation, ensuring uniform tension when the demonstration paper 3 rolls and preventing the demonstration paper 3 from shifting or getting stuck.

[0060] like Figure 5 As shown, in one embodiment, the motor 4 is fixed relative to the upright frame 11 via the crossbeam 12, and the motor 4 drives the drive roller 21 to rotate via the synchronous belt.

[0061] In one embodiment, the transmission component is a transmission belt, which is connected to the output end of the motor 4 and the first rotating shaft 211 of the drive roller 21. The motor 4 controls the drive roller 21 through the transmission belt, which can reduce noise during transmission control and avoid damaging the display atmosphere.

[0062] Optionally, a first transmission gear is fixedly sleeved on the first rotating shaft 211 of the active roller 21, and a second transmission gear is sleeved on the output end of the motor 4. The first transmission gear and the second transmission gear mesh to drive the active roller 21 to rotate.

[0063] Both the first transmission gear and the second transmission gear are helical gears.

[0064] It should be noted that helical gears reduce transmission noise and increase torque to improve transmission efficiency, thus avoiding the problem of elastic deformation of the transmission belt.

[0065] The first transmission gear has more teeth than the second transmission gear to increase torque, ensure smooth driving of the demonstration paper 3, avoid jamming, reduce noise, and improve control precision.

[0066] In some embodiments, the motor 4 is located inside the demonstration paper 3 and is fixedly connected to the stand 11. It is understood that the demonstration paper 3 is sleeved on the outside of the two rollers, and a gap is left between the demonstration papers 3 on both sides for the installation and fixing of the motor 4. Figure 2 The motor 4 shown in the illustration is for illustrative purposes only and does not represent a limitation on the structure of the motor 4.

[0067] like Figure 4 As shown, an image recognition component 51 is fixedly connected to the side of the display screen 5 near the presentation paper 3. The image recognition component 51 is used to scan the presentation paper 3 to determine the position of the presentation paper 3. The image recognition component 51 is electrically connected to the motor 4 to drive the active roller 21 to rotate according to the position of the presentation paper 3.

[0068] like Figure 5 As shown, in one embodiment, the image recognition element 51 is disposed at the bottom of the display screen 5, and there are two image recognition elements 51, which are located on opposite sides.

[0069] In some implementations, the presentation paper 3 is provided with corresponding identifiers, such as barcodes or other specific patterns, to help determine the current position of the presentation paper 3.

[0070] It is understandable that as the usage time increases, the presentation paper 3 may shift to a certain extent, and this shift will continue to accumulate, causing misalignment between the content displayed on the presentation paper 3 and the display screen 5. Therefore, the position of the presentation paper 3 is determined by the image recognition component 51, and the presentation paper 3 can be reset by the motor 4 to eliminate errors and improve synchronization.

[0071] It should be noted that the image recognition component 51 is electrically connected to the processor. After the processor processes the information collected by the image recognition component 51, it drives the motor 4 to operate to achieve a reset.

[0072] In some embodiments, the display screen 5 is clamped and connected to the support frame 11 on both sides, and is relatively fixed to the support frame 11 by bolts or pins. The support frame 11 has multiple corresponding mounting holes for adjusting the position of the display screen 5 and adjusting the height of the display screen 5, so as to accommodate users of different heights.

[0073] Optionally, the physical interactive newspaper viewing and display device 100 further includes a tensioning component 7, which includes a tensioning rod 72 and a first rotating wheel 71. The first rotating wheel 71 is rotatably connected to the outside of the stand 11, and the tensioning rod 72 is fixedly connected to the first rotating wheel 71 and rotates around the axis of the first rotating wheel 71. The surface of the tensioning rod 72 abuts against the demonstration paper 3. The rotation of the first rotating wheel 71 drives the tensioning rod 72 to move, so as to adjust the tension force of the tensioning rod 72 on the demonstration paper 3.

[0074] like Figure 3 As shown, it can be understood that the tensioning roller 72 forms an eccentric adjustable mechanism along the axis of the first rotating wheel 71. By adjusting the first rotating wheel 71, the position of the tensioning roller 72 can be adjusted, thereby adjusting the tension of the demonstration paper 3 and preventing the demonstration paper 3 from becoming loose.

[0075] Furthermore, the tensioning component 7 also improves the convenience of transportation. When the demonstration paper 3 is assembled after transportation, it may shift or become loose. However, by adjusting the tensioning component 7, the tension of the demonstration paper 3 can be adjusted to ensure that it can still be stably displayed after reassembly after transportation.

[0076] Furthermore, the tensioning rod 72 includes a rod body and a rod shaft, the rod body and the rod shaft are rotatably connected, and the rod shaft is fixedly connected to the first rotating wheel 71. Since the rod body and the rod shaft can rotate relative to each other, when the demonstration paper 3 moves, the rod body that abuts against the demonstration paper 3 can rotate, reducing the friction on the demonstration paper 3 and ensuring the stability of the movement of the demonstration paper 3.

[0077] like Figure 5 As shown, in some embodiments, there are multiple tensioning components 7, which are respectively disposed on the outside of the two uprights 11. The rods of the two oppositely disposed tensioning components 7 are the same, and the two ends of the rods are respectively connected to the rod shafts of the two tensioning components 7. It can be understood that the rod shafts on both sides can support a larger rod, thereby increasing the contact area between the tensioning rod 72 and the demonstration paper 3 and increasing the tension force.

[0078] Optionally, the tensioning assembly 7 further includes a connecting rod 711, one end of which is fixedly connected to the first rotating wheel 71, and the connecting rod 711 is arranged radially along the first rotating wheel 71, and the end of the connecting rod 711 away from the first rotating wheel 71 is fixedly connected to the tensioning rod 72.

[0079] The stand 11 has an arc-shaped window 111, and the tensioning rod 72 passes through the arc-shaped window 111 to abut against the demonstration paper 3.

[0080] It is understood that the connecting rod 711 can increase the range of motion of the tensioning roller 72, thereby achieving a wider range of adjustment;

[0081] like Figure 5 As shown, in one embodiment, the connecting rod 711 is fixedly connected to a tension spring 74. The end of the tension spring 74 away from the connecting rod 711 is fixedly connected to the stand 11. When the tensioning rod 72 abuts against the demonstration paper 3, the tension spring 74 is in a stretched state. The tension spring 74 pulls the connecting rod 711 toward the side of the demonstration paper 3 that is abutted by the tensioning rod 72 to ensure tension.

[0082] The arc-shaped window 111 is matched with the moving path of the tensioning rod 72. It can be understood that since the first rotating wheel 71 is located on the outer side of the stand 11, the tensioning rod 72 abuts against the demonstration paper 3 through the arc-shaped window 111. Furthermore, the arc-shaped window 111 acts as a guide rail, which can withstand the lateral force generated during the tensioning process, reduce the bending stress of the connecting rod 711, and extend its service life.

[0083] Optionally, the tensioning assembly 7 further includes a second rotating wheel 73, which is rotatably connected to the outside of the upright 11. The diameter of the second rotating wheel 73 is larger than the diameter of the first rotating wheel 71, and the second rotating wheel 73 and the first rotating wheel 71 are engaged.

[0084] The second rotating wheel 73 is provided with a fastener, which increases the friction between the second rotating wheel 73 and the upright frame 11 to achieve relative fixation between the second rotating wheel 73 and the upright frame 11.

[0085] It is understandable that the diameter of the second rotating wheel 73 is larger than that of the first rotating wheel 71, so that less force is required to rotate the second rotating wheel 73 to drive the first rotating wheel 71 to rotate, thus improving the convenience of adjustment;

[0086] Furthermore, the fasteners can restrict the second rotating wheel 73. Since the first rotating wheel 71 and the second rotating wheel 73 engage, the first rotating wheel 71 is indirectly fixed, preventing the tensioning roller 72 from shifting during use. Also, since the diameter of the second rotating wheel 73 is larger than that of the first rotating wheel 71, when the second rotating wheel 73 is fixed by the fasteners, the first rotating wheel 71 needs to overcome the restriction of the second rotating wheel 73 to rotate, making it difficult to rotate easily. This ensures both ease of operation and high reliability.

[0087] In some embodiments, the second rotating wheel 73 and the axis of the drum are on the same straight line, but they are not connected, so as to avoid the second rotating wheel 73 restricting the rotation of the drum.

[0088] Optionally, the first rotating wheel 71 has a limiting groove on one side near the upright frame 11. The groove is provided with a first elastic member and a first abutting member. One end of the first elastic member is connected to the bottom of the limiting groove, and the other end is connected to the first abutting member. The first abutting member abuts against the outer side of the upright frame 11, and the first elastic member is in a compressed state.

[0089] It is understood that the friction between the first rotating wheel 71 and the stand 11 can be increased by the first elastic member and the first abutting member, which not only prevents the tensioning roller 72 from shifting due to the demonstration paper 3 during use, but also improves the accuracy of adjustment.

[0090] Optionally, the presentation paper 3 includes a first paper surface near the display screen 5 and a second paper surface away from the display screen 5;

[0091] There are four tensioning components 7, which are located on the uprights 11 on both sides. The tensioning rods 72 of the four tensioning components 7 are all in contact with the inner side of the first paper surface, and the four tensioning rods 72 are located at the four corners of the first paper surface.

[0092] It is understandable that, since the presentation paper 3 is fitted onto the outside of the two rollers, it will form a first paper surface close to the display screen 5 and a second paper surface away from the display screen 5. In the actual display process, the user is usually located on one side of the display screen 5 and sees the first paper surface, which is square in shape.

[0093] The four tensioning components 7 abut against the first paper surface, making the first paper surface seen by the user flatter and ensuring the stability of the movement of the demonstration paper 3.

[0094] It is understood that the four tensioning components 7 are respectively located on the two sides of the uprights 11. The uprights 11 have four corresponding arc-shaped windows 111. In some embodiments, the arc-shaped windows 111 are marked with scales so that the four tensioning rods 72 can be adjusted to the same angle for support, so that the supported first paper surface is parallel to the plane of the display screen 5, thereby improving the display effect.

[0095] It should be noted that the tensioning roller 72 can abut against the first paper surface to achieve the tensioning effect or abut against the second paper surface to achieve the tensioning effect; this embodiment does not limit this.

[0096] Optionally, the rotating component 61 is a handwheel, which is rotatably connected to the upright frame 11. The detection component is a rotary encoder, which is located at the end of the second rotating shaft of the handwheel and connected to the second rotating shaft, and is used to detect the rotation of the handwheel. The rotary encoder is electrically connected to the motor 4 and the display screen 5.

[0097] It is understood that the rotary encoder can acquire information about the rotation of the handwheel, such as the direction, angle, and speed of rotation. The rotary encoder is electrically connected to the processor. After processing the information acquired by the rotary encoder, the processor controls the display screen 5 and the servo motor to display the information, so that the movement direction of the demonstration paper 3 is consistent with the rotation direction of the handwheel, and the movement speed of the demonstration paper 3 corresponds linearly to the rotation speed of the handwheel. Compared with traditional touch screen displays, this not only reduces costs but also improves the accuracy of operation and enhances the fun.

[0098] It should be noted that the support frame 11 includes a mounting bracket for mounting the control component. The handwheel is rotatably connected to the mounting bracket. The rotary encoder is located at the end of the second rotating shaft of the handwheel and is fixedly mounted on the mounting bracket. The acquisition end of the rotary encoder is fixedly connected to the second rotating shaft to acquire the rotation information of the handwheel.

[0099] Optionally, the mounting bracket is provided with a limiting member to restrict the rotation direction of the rotating member 61.

[0100] In one embodiment, the limiting member includes a ratchet and a pawl. The ratchet is fixedly mounted on the second rotating shaft, and the pawl is correspondingly mounted on the mounting bracket. The ratchet and the pawl limit the rotation direction of the handwheel.

[0101] In another embodiment, the limiting member includes a limiting block and a first limiting rod, the first limiting rod being rotatably connected to the mounting bracket, the limiting block being located on one side of the first limiting rod and abutting against the first limiting rod, and a torsion spring being provided at the connection between the first limiting rod and the mounting bracket, the torsion spring pushing the first limiting rod to flip toward the limiting block;

[0102] The second rotating shaft is provided with a second limiting rod, which is correspondingly set with the first limiting rod. When the handwheel rotates, the first limiting rod is located within the movement path of the second limiting rod. The handwheel can be rotated in one direction through the limiting block and the first limiting rod. It should be noted that the limiting member can be one or more, and this embodiment does not make specific restrictions on this.

[0103] Optionally, the mounting bracket is equipped with a damping element to increase the damping force between the handwheel and the mounting bracket. This not only simulates the friction force that needs to be overcome when rotating the demonstration paper 3 by the handwheel, but also improves the rotation accuracy of the handwheel, making it easier for users to view and browse.
