This application claims all benefits accruing under 35 U.S.C. §119 from China Patent Application No. 201420694271.7, filed on Nov. 18, 2014 in the China Intellectual Property Office, the disclosure of which is incorporated herein by reference. This application is related to a commonly-assigned application entitled, “A Multifunctional Protective Case With Wireless Router Functionality” filed concurrently, Attorney Docket No.: U 019404-5.
The present disclosure herein generally relates to an electronic device package field, more specifically, relates to a protective case for a tablet computer.
The customers who have purchased a tablet computer generally use it to watch films or various TV shows in a Cafe, on travel or in bed, thus a tablet protective case with multi-angle support becomes the option of many customers. At present, Apple protective case and other protective cases provided by third parties generally have protective functionality. In addition, to attract customers, the vendors will design a multi-angle support with the protective case.
Many protective cases on the market appear to be a three-fold design as illustrated by

The present disclosure is described in relation to a protective case for a tablet computer.
Referring to
The protective case comprises a front plate 110, a holding plate 120 and a supporting plate 130 connecting the front plate 110 and the holding plate 120 via a bendable portion 140. Each of the front plate 110, the holding plate 120, the supporting plate 130 and the bendable portion 140 has a rectangular configuration and a same length along an extending direction of the bottom end 240 of the tablet computer 200.
The front plate 110 comprises at least one magnetic element 112 embedded in the front plate 110. The front plate 110 comprises a first surface 111. When the tablet computer 200 is not in use, the first surface 111 of the front plate 110 is attached to the display surface 210 to protect the display surface 210. When the tablet computer 200 is in use, the bottom end 240 of the tablet computer 200 stands on the top surface 111, the front plate 110 can support the bottom end 240 of the tablet computer 200.
The at least one magnetic element 112 comprises a plurality of parallel magnetic protrusions. In one embodiment, the at least one magnetic element 112 of the protective case is two parallel magnetic protrusions: a first magnetic protrusion 114 and a second magnetic protrusion 115 which are embedded in the front plate 110 of the protective case. The second magnetic protrusion 115 is closer to the bendable portion 140, compared with the first magnet protrusion 114. Top surfaces of the first and second magnetic protrusions 114, 115 are coplanar with the first surface 111. The at least one magnetic element 112 can be a first permanent magnet corresponding to the permanent magnet or the ferromagnetic element of the tablet computer 200. A magnetic pole of the first permanent magnet towards the bottom end 240 of the tablet computer 200 is opposite to that of the permanent magnet or the ferromagnetic element of the tablet computer 200 towards the first surface 111.
The holding plate 120 comprises a first holding element 121, The first holding element 121 holds the back of the tablet computer 200 by a latch mechanism. In one embodiment, the holding element 121 comprises a pair of latches for clapping the pair of adjacent peripheral corners which are far away from the bottom end 240. In this way, when the protective case is in a supporting state to prop up the tablet computer 200, the at least one magnetic element 112 is capable of attracting the tablet computer 200 by the permanent magnet or the ferromagnetic element installed in the tablet computer, and the holding element 121 on the holding plate 120 can secure the back of the tablet computer 200, thus preventing the tablet computer 200 from slipping out of the protective case. There is a fold at a joint between the holding plate 120 and the supporting plate 130. The holding plate 120 or the supporting plate 130 can be rotated around the fold.
When the protective case is in the supporting state to prop up the tablet computer 200, the holding plate 120 is attached to an upper portion of the back of the tablet computer 200, the bottom end 240 of the tablet computer 200 is secured on the first magnetic protrusion 114, the first magnetic protrusion 114 will attract with the bottom end 240 of the tablet computer 200 and the supporting plate 130 is spaced from a lower portion of the back of the tablet computer 200. Meanwhile, the holding plate 120 and the supporting plate 130 are folded at the fold to form a certain angle in order to secure and support the tablet computer 200. For the above situation, the tablet computer 200 and the first surface 111 form a 60° acute angle, thus enabling the tablet computer 200 to stand up at a 60° angle towards the first surface 111. Similarly, when the bottom end 240 of the tablet computer 200 is secured on the second magnetic protrusion 115, by the attraction of the magnetic element 112 with the bottom end 240 of the tablet computer 200, facilitated by the secure and support of the holding plate 120 and the supporting plate 130, the tablet computer 200 can stand up at a 45° angle towards the first surface 111.
It should be noted that the tablet computer 200 standing up at a 60° angle or a 45° angle is only one specific mean to illustrate that the protective case can support the tablet computer 200 to stand up at different angles, and it is not intended to be limiting, and similarly, by installing the at least one magnetic element 112 on different positions on the first surface 111 the tablet computer 200 can also stand up at other angles.
The holding plate 120 comprises a first coating layer 123 and a first plate 124 enclosed in the first coating layer 123. The supporting plate 130 comprises a second coating layer 131 and a second plate 132 enclosed in the second coating layer 131. The first coating layer 123 and the second coating layer 131 are connected with each other to form an integrity, and a gap D is determined in the first plate 124 and the second plate 132. The gap D is for instance, 6 mm in width as illustrated in
PU is the abbreviation of polyurethane, and PU leather stands for the leather containing polyurethane constituents. PU leather has broad applications in luggage, clothing, furniture and many other territories for its outstanding abrasive resistance, breathability and ageing resistance together with its strong flexibility and soft and comfortable texture. Wherein the PU leather being applied to the material of the first coating layer 123 and the second coating layer 131, its abrasive resistance, softness and other excellent properties can meet the material requirements of the protective case for the tablet computer. Meanwhile, PC is short for polycarbonate, and polycarbonate is the major constituents of PC plates. The PC plates are sheet material made by thermal forming technologies, and have extensive applications in for instance, package and other territories for its light weight and good mechanical properties.
In the protective case according to this embodiment, a display window 113 is arranged on the first surface 111 near the magnetic element 112 to display the battery status of the tablet computer 200.
A first hole 122 is further defined in the holding plate 120 of the protective case near the first holding element 121. The first hole 122 is in accordance with the camera 230 of the tablet computer 200 in position. The tablet computer 200 can be used not only to get online, but also to shoot a photograph or a video, thus the installment of the first hole 122 facilitates the shooting of the tablet computer 200 when it is used as a camera that the protective case needs not to be taken off.
The first surface 111 of the front plate 110 adhering to the display surface 210 of the tablet computer 200 can be made by a soft material. When the protective case is closed to protect the tablet computer 200, this surface adheres to the display surface 210 of the tablet computer 200, wherein the option of the soft material can well protect the display surface of the tablet computer, thus preventing the display surface 210 of the tablet computer 200 from being scratched.
It should be noted that above embodiments are merely exemplary ones of the present invention. Obviously, the present invention is not limited to above embodiments, but has many variations. All variations that a person skilled in the art derives from or directly reaches form the contents disclosed in the present invention shall be considered as falling into the protective scope of the present invention.
