Description

Technical Field

[0001] The utility model relates to the technical field of electronic book page turning, in particular to a clamping device with adaptive thickness for an electronic book page turning device. Background Art

[0002] E-book page turner technology is an innovative interactive technology that simulates the page turning effect of traditional paper books, bringing readers a new reading experience. The emergence of this technology not only enriches the way of reading e-books, but also enhances users' reading interest and interactivity.

[0003] The e-book page turner technology is mainly based on the research results in the fields of computer vision, human-computer interaction and multimedia technology. First, through computer vision technology, the system can accurately capture the user's actions and gestures, such as finger sliding, page turning, etc. Then, human-computer interaction technology converts these actions into e-book page turning instructions to achieve the page turning effect. Finally, multimedia technology is responsible for presenting the content of the e-book, including text, pictures, audio and video, etc., to provide users with a rich and diverse reading experience.

[0004] Compared with the traditional way of turning pages in e-books, e-book page turner technology has many advantages. First, it simulates the page turning effect of paper books, allowing users to experience a more realistic page turning experience when reading e-books. Second, page turner technology can be personalized according to the user's actions and habits to meet the reading needs of different users. In addition, page turner technology can also be combined with other functions, such as adding bookmarks, searching content, etc., to provide users with more convenient reading services.

[0005] With the continuous development of technology, e-book page turner technology is also constantly being updated and improved. In the future, we can expect a more natural and smooth page turning effect, as well as a more intelligent and personalized reading experience. At the same time, as the e-book market continues to expand, e-book page turner technology will also be more widely used and promoted, bringing high-quality reading experience to more readers.

[0006] In summary, e-book page turner technology is an innovative interactive method that integrates multiple technologies such as computer vision, human-computer interaction and multimedia technology. It not only simulates the page turning effect of traditional paper books, but also brings users a more convenient and personalized reading experience. With the continuous advancement of technology and the expansion of its application scope, e-book page turner technology will play a more important role in the future.

[0007] However, although the clamping parts on the electronic book page turning devices currently on the market provide a convenient reading and page turning experience to a certain extent, they still have some obvious disadvantages, as follows:

[0008] 1. Limited scope of application: The clamps on e-book turning devices of different brands and models are usually only suitable for e-book readers or tablets of specific sizes and thicknesses, which limits their wide application. For those who have multiple sizes of devices or frequently change devices, they may need to purchase multiple page turner clips, which increases costs and inconveniences.

[0009] 2. Insufficient clamping stability: Since the clamping parts on the e-book page turning device are fixed to the main body, the thickness of the e-books, mobile phones, tablet computers and other digital products they match is inconsistent, resulting in the non-slip pads on the clamping parts not being able to fully fit the screen of the corresponding digital product, resulting in unnatural and insensitive page turning movements, and even due to unstable clamping, it is easy to slip or fall off. This not only affects the user experience, but may also cause damage to the device.

[0010] In summary, although the electronic book page turning devices currently on the market have improved the convenience of reading to a certain extent, the disadvantages of their clamping parts cannot be ignored, which greatly affects the user experience and needs to be improved. Therefore, an electronic book page turning device with adaptive thickness is proposed herein. Utility Model Content

[0086] Working principle of this utility model:

[0087] The host 1 includes an upper clamping body 11, and the upper clamping body 11 includes a clamping bracket 111. A movable cavity 1116 is opened at the bottom of the front end of the clamping bracket 111. An upper hemispherical space 1115 is opened at the bottom of the movable cavity 1116. A first buckle 1117 is set in the movable cavity 1116 in the clamping bracket 111; the clamping assembly 13 is fastened and connected with the first buckle groove 1353 and the first buckle 1117, so that the lower hemispherical cavity 1351 opened by the connecting plate 135 in the clamping assembly 13 and the upper hemispherical cavity 1115 opened by the clamping bracket 111 form a spherical cavity 16, and wrap the movable ball 134. The movable ball 134 rotates freely in the spherical cavity 16.

[0088] The movable ball 134 passes through the clamping plate 135 and is connected to the clamping plate 131 through the connecting rod 133. The electrode column 136 is connected to the clamping plate 131, and the clamping plate is also provided with a first groove 1315. The first groove 1315 is covered with a soft upper anti-skid pad 132. The upper anti-skid pad 132 is tightly attached to the bottom end of the electrode column 136.

[0089] Since the bottom of the lower hemispherical cavity 1351 of the clamping plate 135 is provided with a swinging groove 1352, the swinging track of the clamping assembly 13 in the swinging groove 1352 in the active cavity 1116 is determined. At the same time, in order to better adapt to the thickness of mobile phones, e-books, tablet computers and other digital products of different thicknesses, the lower end surface of the active cavity 1116 of the clamping plate 111 is provided with an avoidance slope 1119 with the active ball 134 as the center.

[0090] The upper clamping body 11 is connected and installed above the lower clamping body 12 through the rotating shaft 15. The two are rotated relative to each other through the rotating shaft 15 to form different height changes between the upper clamping body 11 and the lower clamping body 12.

[0091] A coil spring 14 is installed between the upper clamping body 11 and the lower clamping body 12. When the clamping assembly 13 of the upper clamping body 11 contacts the screen of a digital product, the coil spring 14 provides power, and the correcting movable ball drives the clamping assembly 13 to adjust the angle in the swing groove 1352, so that the clamping assembly 13 fits the screen of a digital product such as an e-book, a mobile phone, or a tablet computer more closely, and the coil spring 14 continuously provides a suitable clamping force to maintain the clamping.

[0092] The wire 137 is welded to the electrode column 136. The wire 137 passes through the wire slot 1314, through the wire hole 1313, the threading square hole 1114 and the second threading hole 1123, through the wire interface 1214, and reaches the circuit board and is welded. The wire 137 and the electrode column 136 provide feedback signals from the screen of the mobile phone, e-book, tablet computer and other digital products held by the host 1, which are amplified and provided to the wireless communication or Bluetooth chip 1241 for processing. When the host 1 is turned on by the switch button 127, the host 1 enters the Bluetooth pairing mode, and the controller paired with it is connected through a wireless signal.
