Description

Cover for a device including a capacitive touch screen

Technical Field

The utility model relates to a lid for including capacitive touch screen's equipment, this lid is particularly suitable for the auxiliary user and is in carry out touch interaction on the touch-sensitive screen.

Background

Today, mobile electronic devices with capacitive touch screens, such as smartphones and tablets, are widely used throughout the world.

The most important feature of these devices is the use of a touch screen that allows the use of a finger. For example, these devices enable games to be easily downloaded using app stores or the like, thereby allowing users to enjoy various games. However, since an input operation should be performed through virtual buttons displayed on the front touch screen in order to manipulate the game, it is difficult to perform the input operation quickly and accurately. Furthermore, the accuracy of virtual button operations is not as good as, for example, a physical gamepad, and the user's fingers may obstruct the view and affect the display. Further, the user cannot experience a desired grip feeling during the operation.

There are some products on the market aimed at solving the above-mentioned problems. CN108339269 provides a modular gamepad for smart phones. However, this gamepad firstly requires an external battery, which entails additional weight and manufacturing costs, and secondly needs to be matched to the game, so that all the buttons on the gamepad are matched to a certain function in the game. It limits the utility model to be used only in designated games.

CN208079192 provides mobile phone protection shell type mobile game peripheral hardware. However, the facility requires special provisions to connect the entertainment buttons with the on-screen virtual buttons.

WO2009036375 provides a user control device suitable for use with an information system. However, after being assembled on a smartphone, it first adds significantly to the size and weight, and does not address the problem of the touch operation blocking the user's view.

A current gap in designing covers for devices that include touch screens is that it should i) aid touch interaction; ii) easy handling and assembly; iii) does not add significant size and weight; iv) electronic equipment can be protected; v) simple design and low manufacturing cost.

Examples of the invention

Example 1

Fig. 1-2 show a preferred embodiment of the first version of the invention. The cover includes:

a body adapted to enclose a smartphone at four edges;

two user interaction points on one edge of the body comprising exposed conductive metal;

two contact points each comprising an exposed electrical coil conductor;

two connections, each electrically linking a conductive metal of the user interaction point to an electrical coil conductor of the contact point;

wherein the cover completely covers the touch screen, wherein the contact points are positioned at a side of the cover facing the touch screen.

The body (3) of the present example is first able to completely cover the touch screen (11), with the contact point (4) positioned on the body covering the touch screen. The body (3) surrounds the electronic device (6) at four edges. Thus, it is ensured that there is no planar displacement (horizontal or vertical) of the cover (1) when assembled onto the smartphone, so that the cover remains stationary. There are two user interaction points (2) located at the edge of the subject.

The user interaction point (2) and the contact point (4) are paired with each other and linked by an electrical connection (5). Both the user interaction point (2) and the contact point (4) comprise exposed conductive elements. Thus, a circuit is built up between the conductive elements in the user interaction point (2) and the conductive elements in the contact point (4). Such that when a user touches a finger on the user interaction point (2), in particular a conductive metal (9), static electricity is transferred from the user's finger to the contact point (4), in particular an electrical coil conductor. Thus, the user virtually touches the touch screen (11). The present embodiment provides two pairs of user interaction points (2) and contact points (4).

The contact point (4) and the electrical connection (5) are positioned close to the edge and the user interaction point (2) is positioned at the same edge so that they do not affect the user's line of sight when using the touch screen. The user interaction point (2) is a button (8) as shown in fig. 3. It comprises a conductive metal (9) and a plastic housing (10). The button (8) is adapted to move upon application of a downward force, whereby this movement establishes an electrical connection between the electrically conductive metal (9) of the button (8) and the electrical connection (5), and finally between the electrical coil conductor of the user interaction point (4). When the user touches the button (2), it gives a responsive force to the user's finger, essentially giving the user a press/tap experience.

The contact point (4) comprises a coil conductor receiving static electricity from a user's finger for operating a specific point on the touch screen (11). It intensifies the static electricity applied to the spot, essentially intensifying the electric field applied to the spot.

The front panel (12) is made of transparent plastic so that it does not affect the user's sight when the touch screen (11) is used. Thus, the contact points (4) are also transparent for the same reason. The front panel (12) comprises two layers. When assembled onto a smartphone (6), the contact point (4) is positioned on the layer (14) closest to the touch screen (11). The additional layer (13) protects the front panel from e.g. scratches and abrasion. The contact points (4) and electrical connectors (16) are located near the edge of the front panel (12) so that they do not interfere with the user's line of sight when the touch screen is in use. The front panel (12) and the contact points (4) are flat, so that when assembled to an electronic device, uneven surfaces are avoided.

The user interaction point (2) and the contact point (4) follow the same design as described in example 1.

When the front panel (12) and the main body (17) are assembled, the electrical connector (15) in the main body (17) and the electrical connector (16) in the panel (12) are electrically connected. In other words, the user interaction points (2), the electrical connectors (15), the electrical connectors (16) and the contact points (4) are grouped. In a preferred embodiment, the cover (1) contains two sets (two sets of above groups), preferably two sets of above groups.

Similarly to example 1, the front panel (12) and the main body (17) are light and thin, and have sufficient rigidity to protect the smartphone.
