Description

Technical Field

[0001] This utility model relates to the field of electronic display technology, and in particular to an electronic display paper. Background Technology

[0002] With the development of camera portability, instant cameras are widely loved by consumers. However, traditional instant cameras generally use physical photographic paper, and the images cannot be erased after they are formed. They are disposable consumables, which not only waste resources but also increase the cost of consumables.

[0003] Meanwhile, in common digital cameras, the display screen needs to be driven by the camera's own power supply to display the images captured by the camera. It cannot be displayed offline without the camera. Currently, no camera has the functions of instant imaging, offline display, and erasable display at the same time.

[0004] Common electronic paper is generally used for content display on tablets and computers. It lacks the ease of operation and structural stability required for instant imaging cameras and cannot be directly applied to the camera field.

[0005] Therefore, this application aims to provide an electronic display paper for instant imaging cameras that is easy to operate, structurally stable, and features offline display and erasure capability. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model proposes an electronic display paper to solve the above-mentioned technical problems.

[0007] This application proposes an electronic display paper, including a first housing, a second housing, and a display component that are parallel to each other. The first housing covers the second housing to form a cavity for accommodating the display component. The display component includes an e-ink screen and a circuit board, and the e-ink screen and the circuit board are electrically connected. The e-ink screen and the circuit board are embedded inside the second housing, and the first housing has a display window corresponding to the display area of ​​the e-ink screen. The second housing has a mating groove extending through the cavity at one end near the circuit board, and the second housing has a mating interface below the mating groove, through which the gold fingers of the circuit board pass from the cavity into the mating groove.

[0008] By adopting the above technical solution, the e-ink screen and circuit board are embedded in the second housing. After the first housing is closed, the user can view the image displayed on the e-ink screen through the display window. At the same time, the e-ink screen is connected to the circuit board, and the gold fingers of the circuit board extend from the inside of the second housing into the mating groove. When the electronic display paper is inserted into the slot of the matching camera, the contacts of the gold fingers can contact the gold finger socket inside the camera through the interface, thereby realizing the connection between the electronic display paper and the camera. The captured image is processed by the various modules inside the camera and then transmitted through the gold fingers and displayed on the display area of ​​the e-ink screen. The image is displayed using the e-ink screen. When the electronic display paper is pulled out of the camera, the image can still be displayed. The display content of the e-ink screen can also be erased and the shooting can continue, realizing the reuse of instant imaging paper.

[0009] Preferably, the inner side of the second housing is provided with a number of equally spaced limiting ribs surrounding the ink screen, and the extending direction of the limiting ribs is perpendicular to the edge of the ink screen.

[0010] By adopting the above technical solution, the second housing uses limiting ribs to restrict the horizontal displacement of the e-ink screen, which plays a positioning role during installation. After installation, it can avoid the positional displacement of the e-ink screen due to shaking, and avoid problems such as the display area not being aligned with the display window.

[0011] More preferably, a plurality of equally spaced support ribs are formed on the bottom surface of the ink screen on the inner side of the second housing. The support ribs extend along the length and / or width of the second housing, and the height of the support ribs is less than the height of the limiting ribs.

[0012] By adopting the above technical solution, the bottom surface of the e-ink screen is supported by equally spaced support ribs. At the same time, the support ribs extend along the length or width of the second housing, or extend in both length and width directions to form a grid-like support structure. This prevents the bottom surface of the e-ink screen from being completely attached to the inner side of the second housing, leaving a certain gap for heat dissipation. The height difference between the support ribs and the limiting ribs allows the e-ink screen to be embedded in the slot formed by the height difference between the two.

[0013] Preferably, the inner side of the second housing is provided with several magnetic slots below the ink screen, and the magnetic slots are evenly distributed in a multi-point manner. Magnetic elements are embedded in the magnetic slots, and the magnetic elements are magnetically connected to the bottom surface of the ink screen.

[0014] By adopting the above technical solution, magnetic attraction elements are embedded in the second housing and evenly distributed at the bottom of the ink screen to provide a uniform magnetic attraction force. When the ink screen is embedded, in addition to being restricted in horizontal displacement by the limiting ribs, it will also be subject to the longitudinal magnetic attraction force generated by the magnetic attraction elements to prevent the ink screen from shifting longitudinally.

[0015] Preferably, the inner side of the second housing has a mounting groove adapted to the size of the circuit board, and the mounting groove has a connection port on the side facing the e-ink screen. The e-ink screen is connected to the circuit board via the connection port through an FPC cable.

[0016] By adopting the above technical solution, the circuit board is individually fixed using the mounting slot, so as to achieve the form of partitioned fixing of the e-ink screen and the circuit board. At the same time, the FPC cable is guided by the connection port to avoid loosening / damage of the FPC cable during the installation process.

[0017] In a further preferred embodiment, the side of the mounting slot furthest from the e-ink screen is connected to the docking slot.

[0018] By adopting the above technical solution, after the circuit board is embedded in the mounting slot, one side is connected to the e-ink screen, and the gold finger part on the other side extends into the docking slot and cooperates with the gold finger socket inside the camera through the docking interface below the docking slot.

[0019] In a further preferred embodiment, the bottom of the mounting groove has a raised positioning post, the circuit board has a corresponding positioning hole, and the inner side of the mounting groove also has a buckle for fixing the circuit board. The positioning post and the buckle are symmetrically distributed based on the width centerline of the second housing.

[0020] By adopting the above technical solution, the circuit board is positioned by aligning the positioning pins with the positioning holes during installation. The positioning pins also serve as horizontal limiters. When the circuit board is fully embedded in the mounting slot, the clips on its inner side will abut against the top edge of the circuit board to prevent longitudinal displacement of the circuit board.

[0021] Preferably, the bottom surface of the second housing near the circuit board is also recessed upward to form a guide groove, the guide groove extends along the length of the second housing, and the guide groove is symmetrically distributed on both sides of the mating groove based on the width centerline of the second housing.

[0022] By adopting the above technical solution, when the electronic display paper is used with the camera, the guide groove plays the role of insertion guide. The camera's card slot will be correspondingly set with guide ribs. During the insertion process, the guide groove will move along the guide ribs until it is inserted into the bottom of the card slot. If the guide groove and the guide ribs are not aligned, the electronic display paper cannot be fully inserted into the card slot. At the same time, the guide groove is only set on the bottom surface of the second housing to prevent users from confusing the front and back of the electronic display paper, which has a foolproof effect.

[0023] Compared with the prior art, the beneficial effects of this application are as follows: This application proposes an electronic display paper that combines the instant imaging advantages of e-ink screens with the ability to retain the image display even after being removed from the camera, and allows for erasable content reuse, breaking the limitation of traditional physical photographic paper being disposable. Simultaneously, a closed cavity is formed by the first and second housings, with the e-ink screen and circuit board embedded in the second housing in an integrated design. This, along with limiting ribs, supporting ribs, and magnetic components surrounding the e-ink screen, and mounting slots, positioning posts, and clips designed for the circuit board, ensures stable installation of all components, preventing misalignment or loosening during use or connection. It also ensures precise alignment between the e-ink screen display area and the display window of the first housing, and prevents damage to components such as the FPC cable and circuit board gold fingers. Furthermore, the second housing's connecting slots, interfaces, and mounting slots, combined with symmetrically distributed guide slots on the bottom, enable stable connection between the electronic display paper and the camera slot, provide guidance during insertion, and prevent users from confusing the front and back. The overall structure is adapted to the needs of instant imaging cameras, balancing convenience, connection stability, and reusability. Attached Figure Description

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This application proposes an electronic display paper. Figure 1 An exploded view of the structure of an electronic display paper according to an embodiment of this application is shown, as follows: Figure 1 As shown, the electronic display paper includes a first housing 01, a second housing 02, and a display component that are parallel to each other. The first housing 01 covers the second housing 02 to form a cavity for accommodating the display component. The display component includes an e-ink screen 03 and a circuit board 04. The e-ink screen 03 and the circuit board 04 are electrically connected. The e-ink screen 03 and the circuit board 04 are embedded inside the second housing 02, and the first housing 01 has a display window 05 corresponding to the display area of ​​the e-ink screen 03. The second housing 02 has a mating groove 06 that extends through the cavity at one end near the circuit board 04, and the second housing 02 has a mating interface 07 below the mating groove 06. The gold fingers of the circuit board 04 pass through the cavity into the mating groove 06.

[0029] Specifically, the contact surfaces of the first housing 01 and the second housing 02 can be fitted together by means of bonding, plugging, screw connection, etc.

[0030] The e-ink screen 03 and circuit board 04 are embedded in the second housing 02. After the first housing 01 is closed, the user can view the image displayed on the e-ink screen 03 through the display window 05. At the same time, the e-ink screen 03 is connected to the circuit board 04. The gold fingers of the circuit board 04 extend from the inside of the second housing 02 into the docking groove 06. When the electronic display paper is inserted into the slot of the matching camera, the contacts of the gold fingers can contact the gold finger socket inside the camera through the interface 07, thereby realizing the connection between the electronic display paper and the camera. The captured image is processed by the various modules inside the camera and then transmitted through the gold fingers and displayed on the display area of ​​the e-ink screen 03. This solution uses the e-ink screen 03 instead of a conventional display screen. The e-ink screen 03 itself has the characteristics of offline display and erasability.

[0031] Preferably, the inner side of the second housing 02 is provided with a plurality of equally spaced limiting ribs 08 surrounding the ink screen 03, and the extending direction of the limiting ribs 08 is perpendicular to the edge of the ink screen 03.

[0032] More preferably, a plurality of equally spaced support ribs 09 are formed on the bottom surface of the ink screen 03 on the inner side of the second housing 02. The support ribs 09 extend along the length and / or width direction of the second housing 02, and the height of the support ribs 09 is less than the height of the limiting ribs 08.

[0033] The limiting ribs 08 and supporting ribs 09 serve to support and limit respectively. As shown in the figure, the e-ink screen 03 has a rectangular cross-section. The limiting ribs 08 are arranged perpendicular to the four sides of the e-ink screen 03 and are evenly distributed on each side. The supporting ribs 09 extend along the length and / or width of the second housing 02. The figure only shows the structure extending along the width direction as a preferred embodiment. In a specific case, the length and width directions can be set simultaneously to form a grid-like support structure. In the figure, the two ends of the supporting ribs 09 are connected to the limiting ribs 08 in the width direction. When extending along the length direction, they are connected to the supporting ribs 09 in the length direction. The supporting ribs 09 and the limiting ribs 08 form a height difference, so that the e-ink screen 03 is embedded in the groove formed by the height difference between the two.

[0034] Preferably, the inner side of the second housing 02 is provided with a plurality of magnetic grooves 10 below the ink screen 03, and the magnetic grooves 10 are evenly distributed in a multi-point manner. The magnetic grooves 10 are embedded with magnetic elements 11, and the magnetic elements 11 are magnetically connected to the bottom surface of the ink screen 03.

[0035] Specifically, the magnetic element 11 is a magnet. As a preferred embodiment, only the magnetic groove 10 and the magnetic element 11 are shown in a four-point distribution in the figure. In practice, a three-point, five-point, or other multi-point distribution method can be adopted according to the usage scenario. The magnetic element 11 provides a uniformly distributed magnetic attraction force. The bottom surface of the e-ink screen 03 will be provided with corresponding magnetic contact points. When the e-ink screen 03 is embedded, in addition to being restricted by the limiting rib 08 in horizontal displacement, it will also be subject to the longitudinal magnetic attraction force generated by the magnetic element 11 to prevent the e-ink screen from shifting longitudinally.

[0036] Figure 2 A partial enlarged view of location A according to a specific embodiment of this application is shown, as follows: Figures 1-2 As shown, a mounting groove 12 adapted to the size of the circuit board 04 is formed on the inner side of the second housing 02. A connection port 13 is provided on the side of the mounting groove 12 facing the e-ink screen 03. The e-ink screen 03 is connected to the circuit board 04 via the connection port 13 through an FPC cable. At the same time, the side of the mounting groove 12 away from the e-ink screen 03 is connected to the docking groove 06.

[0037] Specifically, the limiting rib 08, which is close to the side of the circuit board 04 and extends along the length of the second housing 02, is connected to the outer wall of the mounting groove 12.

[0038] The mounting slot 12 secures the circuit board 04 separately, thus achieving a partitioned fixation of the e-ink screen 03 and the circuit board 04. At the same time, the connector 13 guides the FPC cable to prevent it from becoming loose or damaged during installation. After the circuit board 04 is embedded in the mounting slot 12, one side connects to the e-ink screen 03, and the gold finger part on the other side extends into the docking slot 06, and mates with the gold finger socket inside the camera through the docking interface 07 below the docking slot 06.

[0039] In a further preferred embodiment, the bottom of the mounting groove 12 is provided with a protruding positioning post 14, the circuit board 04 is provided with a corresponding positioning hole 15, and the inner side of the mounting groove 12 is also provided with a buckle 16 for fixing the circuit board 04, and the positioning post 14 and the buckle 16 are symmetrically distributed based on the width centerline of the second housing 02.

[0040] Positioning is achieved by aligning the positioning post 14 with the positioning hole 15. The positioning post 14 also serves as a horizontal limiter. When the circuit board 04 is fully embedded in the mounting groove 12, the latch 16 on its inner side will abut against the top edge of the circuit board 04 to prevent the circuit board 04 from shifting longitudinally.

[0041] Figure 3 A schematic diagram of the bottom structure of the second housing according to a specific embodiment of this application is shown, as follows: Figures 1-3 As shown, the bottom surface of the second housing 02 near the circuit board 04 is also recessed upward to form a guide groove 17. The guide groove 17 extends along the length direction of the second housing 02, and the guide groove 17 is symmetrically distributed on both sides of the mating groove 06 based on the width centerline of the second housing 02.

[0042] Specifically, when forming the interface 07, a mating groove 06 is first formed at one end of the second housing 02, extending into the cavity. Then, an opening is made in the area corresponding to the mating groove 06 on the bottom surface of the second housing 02, so that the mating groove 06 has a downward-opening opening, which is the interface 07. When the gold finger part of the circuit board 04 is inserted into the mating groove 06, the side where its gold finger contact is located faces the interface 07, so that the gold finger contact can directly mate with the gold finger socket when the electronic display paper is inserted into the camera.

[0043] When the electronic display paper is used with the camera, the guide groove 17 serves as an insertion guide. The camera's card slot has corresponding guide ribs. During insertion, the guide groove 17 will move along the guide ribs until it is inserted into the bottom of the card slot. If the guide groove 17 is not aligned with the guide ribs, the electronic display paper cannot be fully inserted into the card slot. At the same time, the guide groove 17 is only set on the bottom surface of the second housing 02 to prevent users from confusing the front and back of the electronic display paper, thus having a foolproof effect.
