Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

The technical solution of the utility model is described in detail with specifically embodiment below.These are specific below Embodiment can be combined with each other, and may be repeated no more for same or analogous concept or process in some embodiments.

It refer to Fig. 1, described containment vessel, including：Housing 1, key device and communication connector 6, the key device bag Keypad 2, N number of button 4 and key circuit are included, wherein, N is positive integer, also is understood as the integer more than or equal to 1；The N Individual button 4 may be contained within the keypad 2 with the key circuit, and the keypad 2 is movably connected on the housing 1；It is described Communication connector 6 is located at the housing 1,

The communication connector 6 is to realize the joint of data interaction, the button suitable for being plugged in the communication interface of terminal Circuit connects the communication connector 6, and the key circuit can be triggered by N number of button 4, to pass through the communication connector 6 Signal is sent to the terminal.

In one of which embodiment, the key device also includes flip piece 3, and the keypad leads to 2 excessively described upsets Part 3 is movably connected on the housing 1, to cause：When the housing 1 is installed on the terminal, the keypad 2 is in upset to work In the front of the terminal when making position.

Wherein, flip piece 3 can be realized in a manner of any achievable upset.In one of which embodiment, flip piece 3 Flexible part can be included, flexible part connects housing 1 and keypad 2 respectively, specifically refers to containment vessel in existing correlation technique Upset mode is realized.In another embodiment, flip piece 3, ring portion can be included, keypad 2 is arranged in ring portion, by by Keypad 2 moves along ring portion, and the upset of keypad 2 can be achieved.Two kinds of citings are these are only, are meeting operating position and ready position In the case of change, those skilled in the art can realize in any way, and all without departing from the scope of this embodiment of above.

Operating position, it can be understood as position during use；Ready position, it can be understood as any not come into operation and energy The position being enough determined.In one of which embodiment, the keypad 2 is overturn to the back of the body in the terminal during ready position Face.

In one of which embodiment, as shown in figure 1, the flip piece 3 is located at the length edge of the housing, so that ：When the housing 1 is installed on the terminal, the length edge of the axis of rotation of the keypad 2 parallel to the terminal.Should Under embodiment, keypad 2 may be reversed in the left and right sides of terminal.In another embodiment, the flip piece 3 is located at described The widthwise edges of housing 1, to cause：When the housing 1 is installed on the terminal, the axis of rotation of the keypad 2 parallel to The widthwise edges of the terminal.Under the embodiment, keypad 2 may be reversed in the both sides up and down of terminal.

In one of which embodiment, the key device also includes the first locking piece, and the housing 1 is provided with the second lock Determine part, first locking piece is located at the keypad, and the keypad is in the operating position and/or the ready position When, mutually locking between first locking piece and the second locking piece, to lock the position between the keypad and the housing Put.First locking piece can be lock 5, and second locking piece is the buckling parts coordinated with the lock 5.

Wherein, keypad 2 can realize locking at the front of upset to terminal, can not when overturning to the back side of terminal Locking is realized, locking can not also be realized.

In addition, keypad 2 can be supported, make it that keypad 2 is not straight when upset is to operating position by the housing 1 The touch-screen of terminal is contacted with, and then plays the effect of protection touch-screen.In one of which embodiment, the width of keypad 2 Degree be more than the gap of housing 1 in the width direction, to allow keypad 2 to be set up in housing 1, meanwhile, on housing 1 can located at The cell body that keypad 2 matches, installed with accommodating keypad 2, realize the restriction of position.
