Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional books, and in particular to an interactive three-dimensional book and a manufacturing process thereof. Background Art

[0002] The 3D book is an innovative product that combines modern technology with traditional book forms. In the early days, the 3D book used simple mechanical devices to display the 3D effect. Today, with the development of holographic projection technology, the design of the 3D book has been revolutionized. Through holographic projection technology, the interference and diffraction principles are used to record and reproduce the real three-dimensional image of the object. This technology can not only produce a three-dimensional aerial illusion, but also make the illusion interact with the entity to create a shocking visual effect. The 3D book can present the scenes and characters in the book in a more vivid and realistic way, making the reader feel as if they are in the story and experience unprecedented interaction and immersion. This innovative combination not only enriches the way of reading books, but also brings a new visual enjoyment to readers.

[0003] For example, the Chinese patent application number 202020250182.9 discloses a virtual book flipping display device, including a host, a physical book with page identification, a reader for reading the page identification, and a projector for projecting a projection image on the physical book. The projector and the reader are both connected to the host in communication; the reader feeds back the read page identification information to the host; the host generates a projection image based on the page identification information, and feeds back the projection image to the projector; the projector projects the projection image onto the physical book. Using the physical book as a projection carrier, the projector projects the virtual book image onto the physical book, and the user can see the content of the virtual book on the physical book, thereby giving the user a real reading experience with a strong interactive effect.

[0004] Similar to the above-mentioned stereoscopic book display device, the holographic device is usually fixedly installed in a venue for display, and the viewer needs to enter the venue to use it, which is inconvenient to use. Although the traditional stereoscopic book can be displayed to the user through a three-dimensional structure, its display content is relatively limited, and it is difficult to display complex structures, and it is difficult to meet the user's usage needs.

[0005] Moreover, the existing foldable stereoscopic book holographic projection equipment is affected by the external lighting environment during actual use, resulting in blurred holographic projection images and affecting the viewing experience. Although such problems can be avoided to a certain extent by increasing the lumen, excessively high lumens can easily cause the equipment to heat up abnormally, posing certain safety hazards.

[0006] At the same time, the existing foldable stereoscopic book holographic projection equipment, after being folded and used many times, its projection screen used for projection is prone to scratches or adsorption of dust and impurities, which will also cause the image of the holographic projection in the pyramid to be blurred, affecting the viewing experience. In addition, if the existing foldable holographic projection equipment is subjected to an accidental impact during use, the holographic device will be damaged and cannot be used. The existing technology lacks a projection device that is resistant to damage.

[0007] Therefore, it is necessary to invent an interactive three-dimensional book and its manufacturing process to solve the above problems. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to solve the inconvenience of existing 3D book holographic equipment and the limitations of traditional 3D book display content, such as Figures 1 to 10 As shown, in a first embodiment of the present invention, an interactive three-dimensional book is provided, including a cover page 1 and a spine 2. Velcro 9 capable of limiting the cover page 1 is respectively provided at both ends of the outer side of each cover page 1 along the length direction of the spine 2. The setting of the Velcro 9 can limit the two cover pages 1 after the three-dimensional book is closed, so as to avoid the problem that the internal structure of the three-dimensional book is damaged due to accidental opening of the three-dimensional book under the influence of external factors.

[0034] In this embodiment, the cover page 1 is composed of an upper and lower double-layer structure, and the upper structure and the lower structure of the cover page 1 are separated by a baffle 6. The three-dimensional book also includes: a projection mechanism 3, including multiple projection screens 31, expansion members 32 between adjacent projection screens 31 and corresponding display screens 33. The expansion member 32 expands and contracts through changes in air pressure to drive the projection screen 31 to unfold and fold, and a limiting cavity corresponding to the display screen 33 is opened on the baffle 6.

[0035] It should be noted that the expansion member 32 has a hollow structure inside and a certain elasticity outside. By arranging the expansion member 32 between adjacent projection screens 31, when the multiple projection screens 31 are switched in different states, the multiple projection screens 31 always maintain a connection relationship, so that the multiple projection screens 31 are unfolded as follows: Figure 1 The inverted pyramid structure shown in FIG. 1 can also enable the projection screen 31 to be folded into a Figure 3 The diamond-like structure shown in the figure enables the projection screen 31 to be unfolded and stored.

[0036] In this embodiment, the projection mechanism 3 also includes a base 34, a plurality of rotating members 35 are provided on the outer side of the base 34, and the base 34 is movably connected to the two cover pages 1 respectively through the rotating members 35, and a hinge 36 is provided on the side of the rotating member 35 close to the projection screen 31, and a plurality of expansion members 32 are movably connected to the hinge 36. By setting the rotating member 35, the positional relationship between the base 34 and the cover page 1 is adjusted, that is, when the three-dimensional book changes from a closed state to an open state, the cover page 1 can drive the base 34 to rotate through the rotating member 35, so that the two cover pages 1 and the base 34 are in a parallel state. Conversely, when the three-dimensional book changes from an open state to a closed state, the cover page 1 can drive the base 34 to rotate through the rotating member 35, so that the base 34 is in a vertical state with the two cover pages 1 at the same time, so that the projection mechanism 3 can change its state following the movement of the cover page 1.

[0037] It should be noted that the hinge 36 and the base 34 are rotatably connected, and the connecting surface between the hinge 36 and the expansion member 32 is an arc-shaped surface. When the multiple projection screens 31 are folded along a certain diagonal line, the expansion member 32 can slide on the arc-shaped surface of the hinge 36, so that the multiple projection screens 31 can switch between a structure similar to an inverted pyramid and a structure similar to a diamond. By rotating the hinge 36, the angle between the projection screen 31 and the base 34 is adjusted, thereby realizing the storage and unfolding of the projection screen 31.

[0038] In this embodiment, each baffle 6 is further provided with a speaker module 7 and a touch screen module 8. A control module is provided below the baffle 6. The control module can control the operation of various electrical components in the three-dimensional book.

[0039] In this embodiment, the three-dimensional book also includes a control mechanism 4, which includes a connecting rod 41, a sliding assembly 42 and a rotating assembly 43. The display screen 33 is arranged above the sliding assembly 42. The sliding assembly 42 includes a first sliding member 421 and a second sliding member 422. The first sliding member 421 and the second sliding member 422 have the same structure and are both slidably connected to the cover page 1. The two first sliding members 421 are distributed vertically to the spine 2, and the two second sliding members 422 are distributed parallel to the spine 2.

[0040] It should be noted that when the three-dimensional book is in the open state, the two first sliding members 421 and the two second sliding members 422 are located outside the projection screen 31 and correspond to the projection screens 31 one by one, so that each projection screen 31 can project video information through the display screen 33.

[0041] In this embodiment, each cover page 1 is provided with a plurality of sliding grooves adapted to the sliding assembly 42, two second sliding members 422 are respectively fixedly connected to two connecting rods 41, and each second sliding member 422 is connected to a first sliding member 421 on one side close to the spine 2. When the two second sliding members 422 are respectively moved away from the spine 2 by the connecting rod 41, the two second sliding members 422 can respectively drive a first sliding member 421 to move away from the spine 2, thereby putting the plurality of display screens 33 into the cover page 1, facilitating the state transition between the two cover pages 1.

[0042] In this embodiment, a connecting hole cooperating with the connecting rod 41 is opened on the side of each cover page 1 away from the spine 2. Each connecting rod 41 includes two binding belts containing multiple magnetic parts. The two binding belts on one side of the same cover page 1 are magnetically connected through the magnetic parts.

[0043] It should be noted that, by configuring the connecting rod 41 to be composed of two straps containing multiple magnetic parts, when it is necessary to control the display screen 33 to slide in the direction of the projection screen 31 and realize holographic projection, the two straps on the same side are brought close to each other, and the two straps are magnetically attracted under the action of magnetic force, so that the projection screen 31 is moved by pulling the straps, and when the three-dimensional book is in a closed state, the two straps are separated from each other and attached to the side of the cover page 1, and the magnetic attraction between the two connecting rods 41 assists the Velcro 9 to limit the three-dimensional book.

[0044] During use, when the three-dimensional book needs to be changed from a closed state to an open state, the restriction of the Velcro 9 on the cover page 1 is first released, and the two binding straps of the same connecting rod 41 are magnetically attracted together, and then the cover page 1 is turned to make the three-dimensional book completely flat on the table. At this time, the two connecting rods 41 are controlled to move in the direction close to the spine 2 at the same time, so that the second sliding member 422 connected to the connecting rod 41 drives the first sliding member 421 to move in the direction of the projection screen 31, and then the projection screen 31 is changed from a folded diamond state to an unfolded inverted pyramid state, and the projection screen 31 is made to correspond one by one with multiple display screens 33 by rotating the hinge 36, thereby completing the unfolded state of the three-dimensional book.

[0045] When holographic projection is required through the projection mechanism 3, the processed video is played by controlling multiple projection screens 31. When the light source on the display screen 33 is reflected by the multiple tilted projection screens 31, a virtual image is finally formed in the middle of the four projection screens 31. Since the video source contains images from four different angles, the light will converge in the central area after reflection to form a three-dimensional moving picture, so that the viewer can see the image from any angle, creating a three-dimensional visual illusion. At the same time, the image is adjusted by the speaker module 7 and the touch screen module 8.

[0046] When the three-dimensional book needs to be changed from an open state to a closed state, the above process can be reversed, thereby effectively solving the inconvenience of existing holographic devices and the limitations of traditional three-dimensional book display content.

[0047] However, after using it for many times, the user found that although the above device solves the inconvenience of existing holographic equipment and the limitation of traditional three-dimensional book display content, in actual use, the three-dimensional book is affected by the external lighting environment, resulting in blurred images of the holographic projection in the pyramid, affecting the viewing experience. Although such problems can be avoided to a certain extent by increasing the lumen, too high lumens can easily cause abnormal heating of the device, posing certain safety hazards. At the same time, the existing foldable holographic projection device, after being folded for many times, its projection screen 31 used for projection is prone to scratches or adsorption of dust impurities, which also causes blurred images of the holographic projection in the pyramid.

[0048] Therefore, in order to solve the above problem, in another embodiment of the present invention, the three-dimensional book also includes: a wedge-shaped piece 37 is respectively provided on both sides of the base 34 along the spine 2 direction, one end of the wedge-shaped piece 37 extends into the base 34 and is wedge-matched with the hinge 36. When the wedge-shaped piece 37 slides toward the base 34, it can push the hinge 36 to move and rotate in the direction close to the projection screen 31.

[0049] It should be noted that the wedge 37 and the base 34 are slidably connected, and a reset spring is provided in the base 34 to reset the wedge 37. The hinge 36 can slide up and down on the base 34. When the first sliding member 421 moves toward the direction close to the spine 2 under the drive of the second sliding member 422, the first sliding member 421 can cooperate with the wedge shape of the wedge 37 and push the wedge 37 to move toward the base 34, thereby driving the hinge 36 to move upward. Since a thread-like guide member compatible with the hinge 36 is provided at the connection between the base 34 and the hinge 36, the hinge 36 can rotate during the upward movement through the setting of the guide member, so that the unfolded multiple projection screens 31 are automatically aligned with the display screen 33, thereby avoiding the problem of the projection screen 31 and the display screen 33 being interlaced, resulting in poor imaging effect.

[0050] In this embodiment, the three-dimensional book also includes an adjustment mechanism 5, wherein the control mechanism 4 is located at the lower layer of the cover page 1, and the adjustment mechanism 5 is located at the upper layer of the cover page 1. The adjustment mechanism 5 includes a limit member 51 connected to the rotating component 43, and a movable member 52 is provided at the other end of the limit member 51. A curtain 53 is provided between the two movable members 52 of the same cover page 1. The curtain 53 moves with the sliding component 42 through the movable member 52 and the rotating component 43 to clean the dust of the projection mechanism 3, and the curtain 53 is detachable and connected to the projection screen 31 to block ambient light.

[0051] It should be noted that the curtain 53 and the movable member 52 are detachably connected, and a Velcro 9 structure is provided on the projection screen 31 , so that the curtain 53 can be connected to the projection screen 31 .

[0052] In this embodiment, the rotating assembly 43 includes a rotating shaft 431 and a telescopic member 432. A fulcrum 433 is provided in the middle of the telescopic member 432. A rotating shaft 431 is provided at each end of the same telescopic member 432. The two rotating shafts 431 connected to the same telescopic member 432 are respectively movably connected to a first sliding member 421 and a limiting member 51. Both ends of the telescopic member 432 can be telescoped.

[0053] In this embodiment, the adjustment mechanism 5 also includes a seal 55, which is composed of a cover plate and a base. The two seals 55 are respectively arranged on the two cover pages 1 and are fixedly connected to the baffle 6. When the three-dimensional book is in a closed state, one ends of the two seals 55 can fit each other, thereby blocking external dust on the outside of the seal 55, effectively solving the problem that dust is adsorbed on the projection screen 31 and the display screen 33 after being placed for a long time, thereby affecting the projection effect.

[0054] It should be noted that when the three-dimensional book is in a closed state, under the interaction of the rotating component 43 and the sliding component 42, the screen 53 can cover the area inside the sealing member 55, thereby further improving the dust removal effect of the device on the projection mechanism 3, and an extrusion spring is provided in the telescopic member 432, and a winding component capable of winding up the screen 53 is provided on the sealing member 55.

[0055] When the three-dimensional book needs to be changed from a closed state to an open state, the two first sliding members 421 are driven to slide in a direction close to the book spine 2 by pulling the connecting rod 41. At this time, since the first sliding member 421 is connected to the limiting member 51 through the rotating assembly 43, the rotating shaft 431 connected to the first sliding member 421 can drive the telescopic member 432 to rotate with the fulcrum 433 as the center of the circle, thereby driving the limiting member 51 to move in a direction away from the book spine 2. In this process, the rotating shaft 431 and the limiting member 51 on the first sliding member 421 on the same side As the distance between the rotating shafts 431 on the projection screen 31 increases, the telescopic member 432 can extend and push the limiting member 51 to drive the curtain 53 to move on the surface of the baffle 6. Due to the setting of the wedge-shaped member 37, the movements of the first sliding member 421, the second sliding member 422, the hinge 36 and the curtain 53 are simultaneous. When the projection screen 31 is in the open state, the curtain 53 does not block the light source of the display screen 33. At the same time, the dust in the sealing member 55 can be effectively collected through the movement of the curtain 53, thereby avoiding the problem of excessive dust affecting the projection effect during the projection process.

[0056] When the external environment light intensity is too high and affects the projection effect of the projection screen 31, the curtain 53 is disassembled and separated from the movable part 52, and the curtain 53 is connected to the end of the projection screen 31 away from the hinge 36, so that the external light is blocked by the curtain 53, so that the light emitted by the display screen 33 is not affected by the external light, and the projection screen 31 can only reflect the light of the display screen 33, thereby overcoming the problem that the three-dimensional book is affected by the external light environment and the influence of dust, resulting in blurred images of the holographic projection in the pyramid and affecting the viewing experience.

[0057] Furthermore, if the existing foldable holographic projection equipment is subjected to an accidental impact during use, the holographic equipment will be damaged and unusable. The prior art lacks a projection equipment that is resistant to damage.

[0058] Therefore, in another embodiment of the present invention, the adjustment mechanism 5 of the three-dimensional book also includes a connecting cavity 54 and a hose 57. The connecting cavity 54 is opened on both sides of each sealing member 55 along the direction of the connecting rod 41. Each connecting cavity 54 is provided with a piston plate 56. The piston plate 56 is fixedly connected to the movable member 52. The movable member 52 can push the piston plate 56 to squeeze the gas in the connecting cavity 54. The connecting cavity 54 is connected to the corresponding hose 57, and the other end of the hose 57 is connected to the inside of the expansion member 32. The movable member 52 squeezes the gas in the connecting cavity 54 and controls the expansion and contraction of the expansion member 32 through the hose 57 to resist the impact force.

[0059] During use, when the three-dimensional book changes from a closed state to an open state, the second sliding member 422 is driven by the connecting rod 41 to move in a direction close to the book spine 2. Through the setting of the rotating assembly 43, the second sliding member 422 can drive the movable member 52 to slide on the sealing member 55 through the limiting member 51. Since the movable member 52 is fixedly connected to the piston plate 56, when the movable member 52 slides on the sealing member 55, the piston plate 56 can move with the movable member 52 and squeeze the gas in the connecting chamber 54, so that the gas in the connecting chamber 54 enters the expansion member 32 through the hose 57 and expands the expansion member 32, so that the multiple projection screens 31 in the folded state are deformed from a diamond structure to an inverted pyramid structure under the expansion of the expansion member 32, thereby realizing the automatic deployment of the device.

[0060] On the contrary, when it is necessary to change the three-dimensional book from an open state to a closed state, the second sliding member 422 is driven by the connecting rod 41 to move away from the book spine 2, so that the piston plate 56 moves toward the book spine 2, and the gas in the expansion member 32 is sucked into the connecting cavity 54 through the setting of the hose 57, so that the multiple projection screens 31 in the unfolded state are deformed from an inverted pyramid structure to a diamond structure under the contraction of the expansion member 32.

[0061] When the projection screen 31 falls accidentally or a foreign object hits the projection screen 31 during the projection process, the projection screen 31 will be subjected to additional force. At this time, the additional force applied to the projection screen 31 can cause the expansion member 32 arranged between adjacent projection screens 31 to expand or contract irregularly. In this state, the gas in the expansion member 32 can flow into the connecting cavity 54 through the hose 57, so that the projection screen 31 is deformed with the force, thereby avoiding the problem of damage to the projection screen 31 caused by hard contact between the projection screen 31 and the foreign object. At the same time, when the impact force of the foreign object on the projection screen 31 gradually decreases and is less than the pressure of the air pressure in the expansion member 32, the projection screen 31 can be restored to its original state under the action of the air pressure, thereby avoiding the problem of foreign objects always sticking to the projection screen 31 and damaging the projection screen 31.

[0062] It should be particularly noted that the present invention combines holographic projection technology with stereoscopic books through the mutual cooperation of devices such as the connecting rod 41, the expansion member 32 and the rotating assembly 43, effectively solving the inconvenience of holographic equipment in the prior art and the limitation of the display content of traditional stereoscopic books. At the same time, through the setting of the rotating assembly 43 and the connecting rod 41, on the one hand, the cleaning of dust on the projection mechanism 3 and the influence of the external light intensity on the device are realized; on the other hand, through the cooperation of devices such as the expansion member 32, the automatic expansion and closing of the stereoscopic book is realized, effectively solving the problem that the angle between the projection screen 31 and the display screen 33 is difficult to maintain consistency, and taking measures to effectively protect the projection screen 31 when the device accidentally falls or foreign objects hit the projection screen 31.
