Abstract

The utility model pertains to telecommunication apparatus, in particular to a keystroke device that is installed at the back of cell phone. The keyboard, characters and patterns are displayed by touch screen. When the thumb touches the touch screen, the signals of the keyboard are input into the chip; when the thumb actuate the keystrokes that are arranged on the back, the signals of the keystrokes is confirmed to input into the chip. The chip on the main circuit board of the cell phone is added with two conductors that are connected with a touch switch or an elastic electricity conductive plate. An opening is arranged at the middle upper part of the shell of the cell phone. The circumference of the opening is provided with positioning rib and a keystroke plate is arranged inside the opening. The touch switch or the elastic electricity conductive plate abuts the inner part of the keystroke plate. The utility model has the characteristic and advantage of reliable and comfortable operation, and when operating, the utility model has the feeling of sinking and rebounding of common keystrokes.

Description

The back-positioned type key device of mobile phone

Technical field

The utility model belongs to telecommunication apparatus, relates in particular to a kind of back-positioned type key device of mobile phone.

Background technology

Touch-screen mobile phone is more popular on the mobile phone market now.It combines display screen and button, and button face and character and pattern show by display screen, map function interface at an easy rate, and its number of keys and interface content greatly improve.But keyboard with touch screen also has a shortcoming, it does not have the regular handset button and presses sinking and the resilience that the back finger can be felt, this doigte to sinking and resilience also be to judge whether button clicks one of successful factor, the button resilience often is not to be having a mind to of people and for it, but the bounce-back of the natural elasticity of button, this also is a kind of sensation that people are accustomed to when operation push-button very much.Keyboard with touch screen is clicked finish back finger or pen must leave the key face, otherwise may cause that the mistake merit does, and this has influenced the randomness and the input efficiency of button operation, and this is concerning need frequently use the mobile phone of button, and touch-screen is not an optimum.

The utility model content

The purpose of this utility model is to be to overcome above-mentioned technological deficiency, and a kind of back-positioned type key device of mobile phone is provided, and is arranged on the top at the mobile phone back side, and forefinger is pressed the definite selection of back-positioned type button behind the button face of thumb selection touch-screen.

In order to realize the purpose of this utility model, the technical scheme that adopts is: a kind of back-positioned type key device of mobile phone, button face and character and pattern are by screen displaying, what the button face of thumb touch touch-screen was imported chip is the signal of selecting this button face, what forefinger was pressed back-positioned type button input chip is the signal of determining to select this button face, on the chip of the main circuit board of mobile phone, set up two leads, be connected with touch-switch or elastic conducting strip group; Offer the hole on the handset shell of middle position on the mobile phone back, the inboard periphery in hole has the location convex tendon, places in the hole and connects the key sheet, and touch-switch or elastic conducting strip prop up the button piece inboard.

The flat shape of described button piece is a rectangle, or circle, ellipse and strip.

Described button piece is 30g～80g by power.

Described button piece can be arranged on the surface of cell phone rear cover plate and cell panel.

Distinguishing feature of the present utility model and beneficial effect have the sensation of the sinking and the resilience of common key-press when being operation, operate reliable and comfortable; This device also can be that a kind of in the formula touched in the multiple operation of mobile phone, makes the selectable leeway of user.

Among the figure: 1 handset shell, 2 holes, 3 button pieces, 4 step limits, 5 touch-switchs, 6 elastic conducting strips, 7 main circuit boards, 8 touch-screens, 9 cell panels, 10 cameras, 11 leads, 12 metal contacts, 13 batteries, 14 cell phone rear cover plates, 15 translucent covers, 16 location convex tendons.

Embodiment

Below in conjunction with embodiment and preferred embodiment structure of the present utility model is further specified.

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of back-positioned type key device of mobile phone, for one-handed performance, button face and character and pattern are by screen displaying, what the button face of thumb touch touch-screen (8) was imported chip is the signal of selecting this button face, what forefinger was pressed back-positioned type button input chip is the signal of determining to select this button face, on the chip of the main circuit board (7) of mobile phone, set up two leads (11), be connected with touch-switch (5) or elastic conducting strip (6) group, touch-switch can be selected standard component for use, the elastic conducting strip group is made up of elastic conducting strip and metal contact (12), generally can be according to the structure of mobile phone and specific design; On mobile phone back cell panel (9), offer hole (2) on the handset shell (1) of middle position, camera (10) avris, place button piece (3) in the hole, the handle of touch-switch or elastic conducting strip prop up the button piece inboard, the inboard periphery in hole is provided with location convex tendon (16), side displacement with the restriction button piece can prevent that also button piece from coming off from the inboard, button piece has step limit (4) to prop up the handset shell inboard, comes off from the handset shell outside to prevent button piece; The area of button piece can make forefinger be easier to prop up more greatly, and its flat shape can be rectangle, or circle, ellipse and strip; Preferably being chosen in the scope of 30g～80g of button piece by power, more free and relaxed when forefinger is pressed; If the mobile phone back side is integral type cell phone rear cover plate (14), button piece can be arranged on the outer surface of cell phone rear cover plate, battery (13) is placed in handset shell inside, touch-switch or elastic conducting strip group can be placed on the main circuit board, translucent cover (15) are set in addition with the protection camera on the cell phone rear cover plate; If button piece is arranged on the outer surface of cell panel, can adopt the elastic conducting strip group, can do very thinly because of the thickness of elastic conducting strip group, on the limit of resilient cell contact on the main circuit board, set up the flexible keypad contact; This device can be touched a kind of in the formula for the multiple operation of mobile phone, makes the selectable leeway of user, and when mobile phone did not use this operation to touch formula, the back-positioned type keypress function can dormancy, is circular as button piece, also can be the auto heterodyne minute surface of camera.Distinguishing feature of the present utility model and beneficial effect have the sensation of the sinking and the resilience of common key-press when being operation, operate reliable and comfortable.
