Description

TECHNICAL FIELD

The present disclosure relates to the field of input devices, and more particularly, to an input device for an intelligent terminal, a shell and an intelligent terminal.

BACKGROUND ART

With the progress of science and technology and economic development, an intelligent terminal with a screen such as a smartphone, a tablet computer and the like is becoming more and more popular, and people can perform an interactive operation with the intelligent terminal through a touch screen or a key on the intelligent terminal. However, when a more complicated interactive operation is performed, such as playing a game, it is difficult to meet requirements of the interactive operation by depending on an input device of the intelligent terminal itself only, which is namely the touch screen and limited keys, and there are problems of insufficient hand-held comfort level, screen sheltering by a thumb during operation of the touch screen and deviation easily occurring on a game control accuracy, thus affecting user's operation experience.

A method of adding an external input device is adopted for the problems above in the prior art, such as a gamepad, and FIGS. 1, 2 and 3 show three existing external input devices respectively. In FIG. 1, the intelligent terminal is embedded into the input device, which means that the intelligent terminal and the input device are integrated into a whole, both ends of the intelligent terminal are provided with operating units of the input device, and a user operates the intelligent terminal through a direction key and a function key on the input device. In FIG. 2, the intelligent terminal is separately connected with the external input device. the intelligent terminal only realizes a function of one display screen, and all operations are completed on the external input device. FIG. 3 shows a rocker device for separately replacing the direction key, and the rocker device is directly attached to the screen to replace a virtual rocker displayed through the touch screen and turn the virtual rocker key into a real rocker. The three input devices above have the following problems:

1. the screen can be sheltered during operation, which affects determination of a displayed content, for example, the rocker device in FIG. 3 can shelter the screen;

2. the device is uncomfortable to hold and is not portable, for example, a holding size of an original intelligent terminal is increased in FIG. 1; and

3. the interactive operation is inaccurate, and an operation skill cannot be fully reflected, for example, an auxiliary operation of the touch screen cannot be performed in FIG. 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIG. 4 which is a structure diagram complying with an input device 2 for an intelligent terminal 1 and a shell 4 according to a preferred embodiment of the present disclosure, the input device 2 is in communication connection with the intelligent terminal 1 and transmits a received input operation to the intelligent terminal 1, and the input operation is displayed on a screen of the intelligent terminal 1. The input device 2 may be connected with the intelligent terminal 1 by Bluetooth communication, and Bluetooth pairing is required before connection.

The input device 2 includes the following portions.

Operating Portion 3

The operating portion 3 is a component for receiving a user operation and may be one or more of a rocker, a button or a rotary knob. The input device 2 may be provided with only one operating portion 3 or a plurality of operating portions 3. The operating portions 3 are arranged on a same side surface of the input device 2 for convenience of concentrated distribution and the user operation.

First Fixing Portion 5

The first fixing portion 5 is arranged on a side surface of the input device 2 for installing and fixing the input device 2.

The input device 2 is assembled and matched with the intelligent terminal 1 through the shell 4, and an inside surface of the shell 4 surrounds the intelligent terminal 1. An outside surface of the shell 4 is provided with a second fixing portion 6 matched and connected with the first fixing portion 5. When the first fixing portion 5 and the second fixing portion 6 are in an assembled state, the input device 2 is located on one side of the shell in a horizontal direction. When the shell 4 is assembled with the intelligent terminal 1, an inside surface corresponding to the second fixing portion 6 is contacted with a top end surface or a bottom end surface of the intelligent terminal 1.

In the embodiment, the input device 2 is not directly assembled with the intelligent terminal 1, but is assembled through the shell 4. An outline of the mainstream intelligent terminal 1 is usually designed as a relatively smooth surface without a structure for mechanical installation such as a buckle, a recess and the like. Therefore, a component that can surround the intelligent terminal 1 such as the shell 4 is required to be used as a bridge, and an internal space of the shell 4 is matched with an external size of the intelligent terminal 1. When using the intelligent terminal 1, people often install a jacket for the intelligent terminal 1, such as a mobile phone shell. Therefore, such jacket can be used as the shell 4 without adding a new component, achieving two things at one stroke. Connection between the input device 2 and the shell 4 is realized by assembling and matching the first fixing portion 5 with the second fixing portion 6. Since the inside surface in the vertical direction corresponding to the second fixing portion 6 is contacted with the top end surface or the bottom end surface of the intelligent terminal, the intelligent terminal 1 is located on one side of the inside surface corresponding to the second fixing portion 6 after installation, and the first fixing portion 5 is located on one side of an outside surface where the second fixing portion 6 is located, which means that the input device 2 is located on one side of the outside surface where the second fixing portion 6 is located. Therefore, the input device 2 and the intelligent terminal 1 are located on both sides of the second fixing portion 6 respectively, thus realizing an installation mode of installing the input device 2 on one end of the intelligent terminal in a single-sided manner.

When the input device 2 is connected with the intelligent terminal 1, the intelligent terminal 1 is put into the shell 4 firstly, and then the input device 2 is connected with the shell 4. When the input device 2 is connected, the operating portion 3 and the screen 7 are ensured to be arranged on a same side to facilitate the user operation.

Further, the first fixing portion 5 and the second fixing portion 6 may be any connecting mechanism of a guide groove, a buckle, a screw, a magnet and a bolt or a combination of at least two of the connecting mechanisms above. The improved embodiment further defines a preferred mode of using the first fixing portion 5 and the second fixing portion 6 as the connecting mechanisms to connect and fix the input device 2 with the shell 4. The connecting mechanism may be a guide groove, a buckle, a screw, a magnet, a bolt and other specific implementation structures, and any one of the structures may be selectively used for connection, or two or more of the connecting mechanisms may be selectively used to realize the first fixing portion 5 and the second fixing portion 6. When the connecting mechanism is the guide groove, the first fixing portion 5 or the second fixing portion 6 is the guide groove, and correspondingly, the second fixing portion 6 or the first fixing portion 5 is a convex portion matched with the guide groove. When the connecting mechanism is the buckle, the first fixing portion 5 or the second fixing portion 6 is the buckle, and correspondingly, the second fixing portion 6 or the first fixing portion 5 is a clamping portion matched with the buckle. When the connecting mechanism is the screw, the first fixing portion 5 or the second fixing portion 6 is provided with a screw hole matched with the screw, and correspondingly, the second fixing portion 6 or the first fixing portion 5 is provided with a screw fixing position allowing the screw to pass through. When the connecting mechanism is the magnet, the first fixing portion 5 or the second fixing portion 6 is provided with the magnet, and correspondingly, the second fixing portion 6 or the first fixing portion 5 is provided with a ferromagnetic metal or a magnet. When the connecting mechanism is the bolt, the first fixing portion 5 or the second fixing portion 6 is provided with a bolt hole matched with the bolt, and correspondingly, the second fixing portion 6 or the first fixing portion 5 is provided with a bolt fixing position allowing the bolt to pass through.

Further, the first fixing portion 5 is a cylindrical convex portion; the second fixing portion 6 is a clamping groove, and a shape of an internal space of the clamping groove is adapted to the convex portion; and when the input device 2 is connected with the shell 4, the convex portion is inserted into the clamping groove. The first fixing portion 5 is matched and connected with the second fixing portion 6 by a clamping groove connection mode in the improved embodiment, which is convenient for the user to disassemble, and when the input device 2 does not need to be used, the input device 2 can be disassembled by sliding in an extension direction of the clamping groove.

Further, the convex portion is a trapezoid, and an upper bottom edge of the trapezoid is connected with the input device 2. A cross-sectional area of the convex portion is a trapezoid, and the upper bottom edge of the trapezoid is a shorter one of two parallel edges of the trapezoid, so that the upper bottom edge of the trapezoid is connected with the input device 2 through such setting, and a lower bottom edge of the trapezoid faces outwardly. When the convex portion is connected with the clamping groove, the convex portion is firmly fixed in the clamping groove due to an action of the trapezoid, and the input device 2 cannot move in a height direction of the trapezoid but can only slide in a direction of a column side of the convex portion. Correspondingly, the second fixing portion 6, which is namely the internal space of the clamping groove, is also a trapezoid corresponding to a size of the convex portion.

Further, the cross section of the convex portion is an asymmetrical shape; and when the input device 2 is connected with the shell 4, a side surface where the operating portion 3 is located has a unique orientation. Such design is to ensure that the operating portion 3 and the screen 7 of the intelligent terminal 1 remain on a same side. If the cross section of the convex portion is a symmetrical shape, when the input device 2 is connected with the shell 4, a surface where the operating portion 3 is located can face upwardly or downwardly, thus having a possibility of installation in two directions. The cross section of the convex portion in the asymmetrical shape is adopted in the improved embodiment, so that the input device 2 can only be installed according to one orientation, and meanwhile, only an orientation of a surface where the screen 7 is located can be ensured to be determined when the intelligent terminal 1 is put into the shell 4. The shell 4 can also be designed as a recess shape with only one unclosed surface, then an installation mode of the intelligent terminal 1 shall be the surface where the screen 7 is located facing the non-closed surface, so that installation orientations of the input device 2 and the intelligent terminal 1 can be determined, and the operating portion 3 and the screen 7 are endured to be arranged on the same side. Correspondingly, a cross section of the second fixing portion 6, which is namely the internal space of the clamping groove, is also an asymmetrical shape corresponding to a size of the cross section of the convex portion.

In other embodiments of the present disclosure, the convex portion may also be in an I-shape, a T-shape and other shapes.

In another embodiment of the present disclosure, the first fixing portion 5 is a screw fixing position; and the second fixing portion 6 is a screw hole. When the input device 2 is connected with the shell 4, the input device is connected with the screw hole by the screw passing through the screw fixing position. A screw fixing mode is adopted in the embodiment, the screw fixing position may be a sheet respectively extending from both ends of one side surface of the input device 2, the sheet is provided with a hole, the screw passes through the hole to be matched and connected with the second fixing portion 6, and the screw hole is provided with an internal screw thread matched with the screw.

Further, the screw hole on an asymmetrical position is arranged in the shell 4, and a correspondingly asymmetrical screw fixing position is arranged on the input device 2, so that the screw fixing position can only be installed when the screw fixing position is corresponding to the screw hole position to ensure that the operating portion 2 has a unique orientation.

In other embodiments of the present disclosure, a connection mode of the input device 2 and the shell 4 may also be buckle connection, which means that the input device 2 and the shell 4 have corresponding buckle structures; and the connection mode may also be guide real connection, and the input device 2 and the shell 4 are respectively provided with a guide rail and a clamping portion corresponding to the guide rail.

As a further improvement to the input device 2, the operating portion 3 includes one or more of a rocker, a button or a rotary knob. The input device 2 may be provided with different types of operating portions 3, such as a combination of the rocker and the button, or a combination of the rotary knob and the button, and may also be provided with only one operating portion 3. The operating portion 3 may be a direction control key formed by a potentiometer, which supports the user to operate in multiple directions, thus having a better operation flexibility.

As a further improvement to the shell 4, the shell 4 includes an annular portion, and an inside surface of the annular portion surrounds a side surface of the intelligent terminal. Since an outline of the intelligent terminal 1 is a smooth continuous surface, a better fixing effect can only be realized by surrounding the side surface of the intelligent terminal, especially a narrow side surface, thus preventing the intelligent terminal 1 from sliding out of the shell 4.

Further, the shell 4 includes a bottom surface, and the annular portion is perpendicular to an edge of the bottom surface. The intelligent terminal 1 is placed in a space formed by the bottom surface and the annular portion, and a back surface of the intelligent terminal 1 is contacted with the bottom surface. In the improved embodiment, the shell 4 forms a semi-closed space with only one hollowed-out surface, which means that a surface corresponding to the bottom surface is hollowed out, and the intelligent terminal 1 is allowed to be put into the shell 4 from the hollowed-out surface, while the screen 7 of the intelligent terminal 1 is ensured to have a unique orientation.

Further, the shell 4 includes an upper cover portion, and the upper cover portion is movably connected with a long edge of the annular portion, and is in an opened state or a closed state respectively. The upper cover portion is correspondingly arranged with the bottom surface in a movable connection mode, and can be turned over and moved at a joint with the annular portion by a shaft. Use states of the intelligent terminal 1 under different conditions are considered in the improved embodiment, when the input device 2 is used, the upper cover portion is opened to expose the screen 7, which is convenient for the user to watch the screen 7, and when the screen 7 is a touch screen, a touch operation can also be performed. When the input device 2 is not used or the intelligent terminal 1 is not used by the user, the upper cover portion is closed, and the screen 7 is sheltered by the upper cover portion, which protects the screen 7 from external damage.

In other embodiments of the present disclosure, the input device 2 and the shell 4 are integrally formed, such as an integrated plastic structure or an integrated metal structure, which also solves a problem on how to connect the input device 2 with the intelligent terminal 1.

The present disclosure further discloses an intelligent terminal 1, which includes the shell 4 above. The intelligent terminal 1 may be designed to include the shell 4 with the second fixing portion 6, so that the shell 4 and the intelligent terminal 1 are connected with the input device 2 as a whole.

The screen 7 may be the touch screen, when the user uses the screen, the intelligent terminal 1 is placed horizontally, and one hand can operate the input device 2 while the other hand can operate the touch screen.

It should be noted that the embodiments of the present disclosure have a better implementation performance and are not intended to limit the present disclosure in any form. Those skilled in the art may change or decorate the technical contents disclosed above into equivalent effective embodiments. Any modification or equivalent change and decoration to the embodiments above according to the technical essence of the present disclosure without departing from the contents of the technical solutions of the present disclosure should still fall within the scope of the technical solutions of the present disclosure.
