Description

Technical Field

[0001] This utility model relates to the field of electronic reader technology, specifically to an electronic reader with a lighting device. Background Technology

[0002] An e-reader is a portable, low-power, high-resolution device specifically designed to display digital versions of written materials such as books, magazines, newspapers, and other printed sources. In most cases, devices with other primary functions, such as netbooks and mobile phones, are also used as e-readers. Here, the term "e-reader" refers specifically to a device designed for displaying text. Most e-readers use a technology called "e-ink" to provide a black-and-white, resizable text display instead of an LCD screen, allowing users to store a library of books, annotate, highlight text, and set bookmarks on a single device.

[0003] E-ink displays work by controlling the black and white particles within microcapsules to display text through electrophoresis. They do not emit light themselves and rely on ambient light reflection to be visible. In dark or low-light environments (such as at night, in tunnels, or indoors after lights are turned off), insufficient ambient light makes the screen content difficult to read. In such cases, an external light source or built-in illumination is necessary for reading. A separate lighting device is required as an auxiliary light source in low-light environments; otherwise, it cannot be used properly. However, a separate lighting device increases storage space when stored and carried, causing inconvenience. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an e-reader with a lighting device to solve the technical problem that current e-readers need to be used with a separate lighting device as an auxiliary light source in environments with insufficient light, otherwise they cannot be used normally. The separate lighting device increases storage space when stored and carried, causing many inconveniences in use.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] Example 1: An e-reader with an illumination device, see [link to example]. Figures 1 to 8 ,include:

[0033] E-reader body 1;

[0034] An illumination mechanism, located on the outside of the e-reader body 1, is used to provide supplemental lighting for the screen of the e-reader body 1. The illumination mechanism includes:

[0035] A fixing frame 2 is ring-shaped and fitted around the outside of the e-reader body 1. The inner sidewall of the fixing frame 2 is provided with a limiting protrusion that cooperates with the outer sidewall of the e-reader body 1. The front opening of the fixing frame 2 corresponds to the screen position of the e-reader body 1 and is sized to fit it. A supplementary light fixture 21 is embedded in the four edges of the inner cavity of the fixing frame 2. The supplementary light fixture 21 is a surface-mount LED lamp. The light emission direction of the supplementary light fixture 21 is towards the screen area of ​​the e-reader body 1 and is inclined at a 45° angle to the screen surface.

[0036] The cover plate 24 covers the rear end of the e-reader body 1 and is detachably connected to the rear opening edge of the fixing frame 2.

[0037] This device, through its supplementary lighting mechanism, achieves the following during use:

[0038] Uniform supplementary lighting without dead angles: The supplementary lighting fixtures 21 are distributed in a ring along the inner edge of the fixed frame 2, and the light from the supplementary lighting fixtures 21 is projected onto the screen surface at an incident angle of 45°, avoiding direct glare and shadow blind spots. It can still maintain clear display in dark scenes, and reduce the visual fatigue of people watching the screen compared to the local strong light illumination of external desk lamps.

[0039] Integrated portability: The fixed frame 2 and the limiting protrusion of the e-reader body 1 form a tight connection, with the thickness only increasing by 3-5mm. There is no need to carry an additional independent lighting device. It can be directly put into a regular-sized pocket or backpack to meet the portability needs of mobile reading scenarios. In addition, the fixed frame 2 protects the outside of the e-reader body 1, improving the drop resistance of the e-reader body 1.

[0040] For details, see Figure 3 A limiting frame 26 is fixedly connected to one end of the cover plate 24 near the rear end of the e-reader body 1. The thickness of the limiting frame 26 is the same as the distance from the cover plate 24 to the rear end of the e-reader body 1. A storage battery 42 is fixedly connected to the cover plate 24 inside the limiting frame 26. A switch 41 is provided on the top of the fixing frame 2. The switch 41 is electrically connected to the supplementary light fixture 21 via a wire through the storage battery 42. The physical button design of the top switch 41 conforms to the thumb operation habit. With the power supply of the storage battery 42, it is convenient for personnel to turn the supplementary light fixture 21 on and off. Furthermore, the thickness of the limiting frame 26 is precisely matched with the installation spacing, and the storage battery 42 is hidden inside the limiting frame 26, thereby avoiding the storage battery 42 from contacting the rear end of the e-reader body 1 when the cover plate 24 is closed, which would cause squeezing damage.

[0041] Further, see Figure 3 and Figure 8 The cover plate 24 is fixedly connected to conductive posts 7 on both sides of the end near the limiting frame 26. The two conductive posts 7 are electrically connected to the positive and negative terminals of the battery 42 through wires. The fixed frame 2 is provided with insertion holes 71 on both sides of the end near the cover plate 24. The two insertion holes 71 correspond to the two conductive posts 7 respectively. The two insertion holes 71 are fixedly installed in the two insertion holes 71. The two conductive springs 72 are electrically connected to the positive and negative terminals of the supplementary light fixture 21 through wires respectively. When the conductive post 7 is inserted into the insertion hole 71, the conductive post 7 contacts the conductive spring 72, so that the conductive spring 72 automatically fits the conductive post 7 when the cover plate 24 is installed, quickly completing the circuit connection. This avoids the traction of the wires affecting the installation and removal of the cover plate 24 when the battery 42 and the supplementary light fixture 21 are directly connected through the wires.

[0042] It is worth noting that, see Figure 5 and Figure 7 The cover plate 24 has a groove 5 at one end away from the limiting frame 26. A connecting shaft 52 is fixedly connected between the two ends of the inner cavity of the groove 5. A support plate 51 is rotatably connected to the outside of the connecting shaft 52 by friction. The support plate 51 can be suspended at any angle within a certain range around the connecting shaft 52. The e-reader body 1 can be supported according to the viewing angle. When not in use, the support plate 51 can be rotated and stored in the groove 5. There is no protrusion when it is put into a bag, which does not affect portability.

[0043] It is worth noting that, see Figure 3 and Figure 4 A first rubber pad 6 is fixedly connected to the limiting protrusion on the inner sidewall of the fixed frame 2, and a second rubber pad 27 is fixedly connected to the outer side of the limiting frame 26. The first rubber pad 6 not only fills the gap between the fixed frame 2 and the e-reader body 1, eliminating the shaking caused by assembly tolerance, but also prevents the frame of the e-reader body 1 from being directly worn and damaged by the limiting protrusion. The second rubber pad 27 prevents the limiting frame 26 from directly contacting the rear end of the e-reader body 1 and causing wear.

[0044] It is worth mentioning that, see Figure 2 The top of the fixed frame 2 is provided with a storage slot 4. The switch 41 is installed in the inner cavity of the storage slot 4, and the depth of the storage slot 4 is greater than the height of the switch 41. The switch 41 is hidden in the storage slot 4 to prevent the supplementary light 21 from being accidentally turned on due to compression when placed in a pocket or bag.

[0045] It is worth mentioning that, see Figure 2 and Figure 6 The cover plate 24 has four round grooves 28 at the four corners of the end away from the limiting frame 26. The inner cavity of the round groove 28 is rotatably penetrated by a fixing bolt 25. The fixing bolt 25 is threadedly connected to the threaded hole on the fixing frame 2. The depth of the round groove 28 is greater than the thickness of the head of the fixing bolt 25. The fixing bolt 25 facilitates the disassembly and assembly of the cover plate 24. With the setting of the round groove 28, the head of the fixing bolt 25 is housed in the round groove 28, avoiding the fixing bolt 25 being placed on the outside of the cover plate 24 and affecting the flatness of the cover plate 24.

[0046] It is worth mentioning that, see Figure 1 The bottom end of the fixing frame 2 is provided with a connection hole 22. The connection hole 22 corresponds to the charging port of the e-reader body 1 and is adapted in size. A charging interface 3 is installed on the fixing frame 2 on one side of the connection hole 22. The charging interface 3 is electrically connected to the battery 42 through a wire. By accurately aligning the connection hole 22 with the charging port of the e-reader body 1, the original charger can be directly inserted to charge the e-reader body 1 without disassembling the lighting mechanism. The charging interface 3 facilitates the charging of the battery 42.

[0047] It is worth mentioning that, see Figure 1The bottom of the fixing frame 2, away from the charging interface 3, has a heat dissipation hole 23, and a dustproof mesh is installed inside the heat dissipation hole 23. The bottom of the fixing frame 2, away from the heat dissipation hole 23, has a sound outlet hole 81. The sound outlet hole 81 is opposite to the speaker of the e-reader body 1 and is adapted in size. The top of the fixing frame 2 has a button hole 8. The button hole 8 is opposite to the power button of the e-reader body 1 and is adapted in size. The heat dissipation hole 23 is located in the non-grip area at the bottom of the fixing frame 2, which facilitates heat dissipation of the e-reader body 1. The dustproof mesh maintains heat dissipation efficiency while preventing small particles from entering the inner cavity, maintaining the long-term reliability of the device. The sound outlet hole 81 does not affect the sound output of the e-reader body 1, and the button hole 8 facilitates the switching on and off of the e-reader body 1.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
