Description
Technical field
The utility model relates to key switching structure, relates in particular to the key switching structure with good button touch feeling and button phonoreception.
Background technology
Button is a kind of by pressure control device, by key face piece, to being installed in body, repeatedly presses, and utilizes key face piece and the mutual interlock of assembly that is installed in body, makes key face piece and is installed in the device that body forms the cyclicity positioning relation of outstanding or contraction state.
Button is widely used in electronic product, provides by pressure-controlled function.Existing press-key structure, has the young sheet button of the pot of employing, has employing silica gel push-button, adopts in addition spring button etc.The young sheet button of pot has clear and melodious button sound effect while pressing, but sense of touch is not as silica gel push-button and spring button.Silica gel push-button and spring button have comfortable handfeel of keys while pressing, but phonoreception is not as the young sheet button of pot.In some high-end Smart Home electronic products, the requirement that existing button cannot consumer Geng Gao.
Utility model content
Therefore, the utility model proposes a kind of key switching structure simultaneously with good button touch feeling and button phonoreception.
The utility model adopts following technical scheme to realize:
A kind of press-key structure, comprise: a button lower cover, one button pcb board, some pots of young sheets, the one button silica gel piece on it with some button salient points, some button fore-sets, on it, there are some button upper covers that are inserted in for button fore-set, one key support and a button cover, this button pcb board is fixedly installed on the bottom of this button lower cover, these some pots young sheets are arranged on the electrode contacts of this button pcb board, this button silica gel piece is arranged on this button pcb board, and the button salient point of this button silica gel piece is corresponding to the position of this pot of young sheet, this button fore-set is arranged on the button salient point of this button silica gel piece, and this button fore-set is inserted in the button fixing hole of this button upper cover, this button upper cover and this button lower cover are fixed, after the bottom of this key support and this button cover is fixed, be fixed on again button lower cover.
Further improved, this button upper cover and this button lower cover are fastened by buckle, and Standard fixed by snap is simple and reliable.
Further improved, this key support and this button lower cover are fastened by buckle, and Standard fixed by snap is simple and reliable.
Further improved, on this key support, there are some lower salient points, with the top of this button fore-set of conflicting, by lower salient point conduction, press structural design advantages of simple.
The utility model adopts as above technical scheme, can make this key switching structure have good button touch feeling and button phonoreception simultaneously, more meets consumer for the demand for experience of some high-end Smart Home electronic products.
Accompanying drawing explanation
Fig. 1 is the structure explosive view of each parts of an embodiment.
Fig. 2 is the structural representation of this each component combination of embodiment.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1 and Fig. 2, the press-key structure of one embodiment, comprising: a button lower cover 1, a button pcb board 2, some (more than 1 or 2) pot young sheet 3, a button silica gel piece 4 on it with some button salient points 41, some button fore-sets 5, on it, have a button upper cover 6, a key support 7 and a button cover 8 of some button fixing holes 61 that are inserted in for button fore-sets 5.This embodiment only be take 2 buttons and is described as example, and the press-key structure of 1 button or 3 above buttons similarly, can be analogized.
In embodiment, this button pcb board 2 is fixedly installed on the bottom of this button lower cover 1.The mode for example snapping in by anchor post is fixed, and conventionally has the interface 21 being connected with external circuit on button pcb board 2, therefore offer the through hole 11 that can snap in this interface 21 on the bottom of this button lower cover 1.The young sheets 3 of these 2 pots are separately positioned on 2 electrode contacts of this button pcb board 2, by the electrode contacts of 3 pairs of key switches of the young sheet of these 2 pots, are directly triggered.This button silica gel piece 4 is arranged on this button pcb board 2, and the button salient point 41 of this button silica gel piece 4 is corresponding to the position of this pot of young sheet 3, by the button salient point 41 of this button silica gel piece 4, presses this pot of young sheet 3.This button fore-set 5 is arranged on the button salient point 41 of this button silica gel piece 4, and this button fore-set 41 is inserted in the button fixing hole 61 of this button upper cover 6, this button upper cover 6 is fixing with this button lower cover 1, after this key support 7 is fixed with the bottom of this button cover 8, then is fixed on button lower cover 1.
Advantageous embodiment, on this key support 7, there are 2 lower salient points 71, with the top of these 2 button fore-sets 5 of conflicting respectively, by lower salient point 71 conduction, press power, structural design advantages of simple.This button upper cover 6 is fastened by buckle with this button lower cover 1, and the surrounding of button upper cover 6 has 4 downward auricles with block button hole 62, and the surrounding correspondence of this button lower cover 1 is provided with 4 buckle plush coppers 13.This key support 7 is fastened by buckle with this button lower cover 1, and the both sides of key support 7 have 2 downward auricles with block button hole 72, and the both sides correspondence of this button lower cover 1 is provided with 2 buckle plush coppers 12.Like this, this button upper cover 6 and this key support 7 and this button lower cover 1 Standard fixed by snap, simple and reliable.
The operation principle of this enforcement is: when press button cover 8 by finger, and will be passed to button fore-set 5 by power by its lower fixing key support 7, by button fore-set 5, pressed the button salient point 41 of button silica gel piece 4, thereby indirectly press this pot of young sheet 3, finally by 3 pairs of button pcb boards of this pot of young sheet, 2 key switch electrode contacts, directly triggered.As long as press like this by finger and press button cover 8, by the internal structure of this embodiment, can merge the feel that silica gel push-button is comfortable and produce the clear and melodious sound of the young sheet button of pot.Visible, the utility model is a kind of key switching structure that has good button touch feeling and button phonoreception concurrently.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection range of the present utility model.
