DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
For the purpose of understanding the technical features, objectives and effects of this application more clearly, specific implementations of this application are illustrated in detail with reference to accompanying drawings.
As shown in FIGS. 1 and 2, an adapter device for tablet computer in preferred embodiments of this application comprises a stylus 2 and an adapter 1 for fixing the stylus 2 onto a tablet computer 3. The adapter 1 is comprised of a buckling part 12 and a plug-in part 11. Herein, the buckling part 12 is configured to fix the stylus 2 and the plug-in part 11 is plugged into an interface port 31 of the tablet computer. The stylus 2 can be attached onto the tablet computer 3 by the adapter 1 so as to bring convenience for user to achieve and improve accuracy of input. It also provides a convenient means for stylus storage to prevent the stylus from loss.
At present, the interface ports 31 on portable electrical equipment such as charging interface, mini-USB interface, audio interface and interfaces on electrical products of Apple Inc. are of standardized design for maximum compatibility. In order to improve the compatibility of adapter 1, the shape and structure of the plug-in part 11 can be designed according to these standardized interface ports 31. The adapter 1 can thus be fixed onto the tablet computer 3 when the plug-in part 11 is plugged into the interface port 31 on the tablet computer 3.
As shown in FIG. 3, the buckling part has a groove 14 which is throughout between both ends and adaptive with the stylus 2. The stylus 2 is fixed within the groove 14 through magnetic attraction. By the use of magnetic force, the stylus 2 can be achieved and stored easily. Specifically, a magnet can be installed on the buckling part 12 and the stylus 2 contains iron element. The stylus 2 can be attached to the arc-shaped surface by magnetic force so that the stylus 2 is fixed onto the adapter 1. It is also possible that the buckling part 12 contains iron element and the stylus 2 is equipped with a magnet.
As shown in FIG. 3, the groove 14 preferably has an arc-shaped cross section. The outer surface of the stylus 2 by which it is attached with the groove 14 is an arc shape adaptive with the groove. It should be understood that the shapes of groove 14 and stylus 2 are not limited as what is illustrated here. Instead, they can be square or any other shapes.
The buckling part 12 is C-shaped and the groove 14 is formed within this C-shaped structure to fix the stylus 2, by which the whole adapter is more aesthetic. As shown in FIG. 5, the buckling part 12 can be a square cylinder in another embodiment, in which case the groove 14 is located on further surface of the square cylinder away from the plug-in part 11.
When the cross section of groove 14 is or smaller than a semicircle, the stylus 2 and the adapter 1 are connected to each other by magnetic force. As shown in FIG. 4, the cross section of groove 14 can be larger than a semicircle in another embodiment. In this case, the stylus 2 and the adapter 1 are connected to each other by being buckled in the buckling part 12. The cross section of groove 14 can also be elliptically arc-shaped. Specifically, the sectional shape of groove 14 can be determined according to the shape of the stylus 2.
As shown in FIG. 3, the adapter 1 is equipped with a bypass interface 13 which is configured to be connected with a peripheral electrically. The plug-in part 11 is also electrically connected with the interface port 31. Any other peripherals such as data cable, charger and earphone can also be electrically connected with the tablet computer 3 through this bypass interface 13. That is, the adapter 1 functions as a connector. For example, the bypass interface 13 can be a USB port or a charging port, by which a connection is established with another computer or with a charger for charging through the use of a data cable. Preferably, the bypass interface 13 is located on a portion of the plug-in part 11 which is out of the interface port 31 of tablet computer 3. When the stylus 2 is fixed on the adapter 1, the tablet computer 3 can also be charged or connected with other peripherals simultaneously. As shown in FIG. 6, the bypass interface 13 can also be arranged on a bottom surface of the groove 14. It can be connected with any other peripherals once the stylus 2 is removed.
Preferably, the bypass interface 13 has the same electrical structure as in the interface port 31 of tablet computer 3 which the plug-in part 11 is plugged into. When the adapter device is plugged into the interface port 31 of tablet computer 3, it will not influence the function of this interface port 31. There is no need to remove the adapter 1 from the interface port 31 when the interface port 31 is needed, which reduces the risk of losing the adapter 1 and stylus 2.
Embodiments of this application are described with reference to accompanying drawings. However, this application will not be limited to the above-mentioned specific implementation. Instead, such specific implementations are for illustration rather than limitation. Under the inspiration of this application, the skill in the art can make many forms without departing from the subject of this application and scope of claims, wherein all these forms are within the protection of this application.
