Abstract
The utility model relates to structure improvement of panel key. The improved structure of panel key of the utility model comprises a keyboard plate, a plastic key piece and screws; wherein the keyboard plate is composed of a circuit board and a plurality of buttons fixedly arranged on the circuit board, the circuit board is provided with a plurality of screw holes; the plastic key piece is composed of a plastic frame body, a support rib arranged on the plastic frame body and an integral structure formed by the way that corresponding plastic keys are connected by virtue of a plurality of elastic crank arms, the plastic frame body and the supporting rib of the plastic key piece are provided with corresponding screw holes corresponding to the positions of the screw holes on the keyboard plate, and the plastic frame body is provided with supporting bumps; and the screw is locked in the screw holes arranged on the keyboard plate and the screw holes arranged on the plastic key piece, and the plastic key piece is fixed above the keyboard plate. The utility model provides an improved panel key structure, the defect that performance of key is poor or key is blocked is avoided, and meanwhile design defect of plastic key piece is overcome, elastic restoring force performance is improved, and service lift is prolonged.
Description
Technical field
The utility model relates to the architecture advances of panel button.
Background technology
The button of the guidance panel of existing electronic product exists the defective that the button performance is not good or block key.Trace it to its cause is because certain defective that the design of panel button exists.Consult Fig. 1, Fig. 2 and shown in Figure 3, specific explanation, existing panel button structure is to be installed with the keypad 1 of button 12 compositions on the circuit substrate (PCBA) 11 by the fixing hole on it, utilize fixed screw 3 to be fixed on the insulating protective layer (Shielding) 2 of panel, with a plastic key sheet 5 embedded back covers (Back Cover) 4 that are heat-fused in, the back cover (Back Cover) 4 that will be fixed with plastic key sheet 5 again assembles up formation with the insulating protective layer (Shielding) 2 that is fixed with keypad 1 again.
By above-mentioned analysis, existing as can be seen panel button structure is subjected to following tolerance factor and each member distance instability of causing easily, thereby causes the generation of the not good or card key of button performance.This Several Factors can be summed up as:
(1) the length dimension tolerance of insulating protective layer (Shielding) 2.
(2) the height dimension tolerance of the bearing on the insulating protective layer (Shielding) 2.
(3) the deformation quantity tolerance of button 12.
(4) the deformation quantity tolerance of back cover (Back Cover) 4.
(5) the deformability tolerance of circuit substrate (PCBA) 11.
In addition, plastic key 51, the elastic force on the existing plastic key sheet 5 crank arm 52 and the design of ribs 53 also exist unreasonable, thereby have influence on the elastic-restoring force performance and the useful life of plastic key 51.
The utility model content
Therefore, the problems referred to above at prior art exists the utility model proposes a kind of improved panel button structure, thereby have exempted the defective of the not good or card key of button performance, simultaneously solve plastic key sheet design defect in the lump, improved its elastic-restoring force performance and useful life.
The technical solution of the utility model is:
The improvement structure of panel button of the present utility model comprises:
One keypad is made up of a plurality of buttons that are installed with on a circuit substrate and its, and circuit substrate is provided with a plurality of screws;
One plastic key sheet, the ribs that is provided with by plastic frame body, plastic frame body, and constitute by the complex root elastic force integrative-structure that connects corresponding plastic key of cranking arm, the plastic frame body of described plastic key sheet and ribs are provided with the corresponding screw corresponding to the position of the screw of keypad, and described plastic frame body is provided with the support salient point;
Screw is locked on screw on the keypad and the screw on the plastic key sheet, and described plastic key sheet is fixed in described keypad top.
Further, described ribs be arranged at each adjacent plastic key between.
Further, the screw on screw on the described keypad and the plastic key sheet is 3, distribution triangular in shape, and described screw is 3.
The utility model adopts as above technical scheme, by screw the plastic key sheet is fixed in the keypad top, form the structure of one, thereby each member distance instability of having avoided existing panel button structure to be subjected to the tolerance factor of several parts easily and having caused, thereby cause the generation that the button performance is not good or block key.And by more ribs is set, structure that can the reinforced plastic button piece is beneficial to the setting of screwhole position on the plastic key sheet simultaneously, and has improved greatly the elastic-restoring force performance and the useful life of plastic key.

Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult Fig. 4, Fig. 5 and shown in Figure 6, the improvement structure of panel button of the present utility model comprises:
One keypad 1 is made up of a circuit substrate 11 and a plurality of buttons 12 of being installed with on it, and circuit substrate 11 is provided with a plurality of screws 13;
One plastic key sheet 5, the ribs 53 that is provided with by plastic frame body 55, plastic frame body 55, and constitute by complex root elastic force 52 integrative-structures that connect corresponding plastic key 51 of cranking arm, the plastic frame body 55 of described plastic key sheet 5 and ribs 53 are provided with the corresponding screw 54 corresponding to the position of the screw 13 of keypad 1, and described plastic frame body 55 is provided with and supports salient point 56;
Preferably, screw 13 and the screw on the plastic key sheet 5 54 on the described keypad 1 are 3, distribution triangular in shape, and described screw 3 is 3.Utilize leg-of-mutton stability, only need 3 screws 3 just keypad 1 and plastic key sheet 5 can be fixed reliably.
Preferably, described ribs 53 be arranged at each adjacent plastic key 51 between.By more ribs 53 is set, structure that can reinforced plastic button piece 5, simultaneously more ribs 53 can be beneficial to the setting of screw 54 positions on the plastic key sheet 5, and more firm plastic frame body 55 structures can make the elastic force that connects on it crank arm and 54 obtain bigger firm holding power and elastic force, thereby the elastic-restoring force performance and the useful life of having improved plastic key 51 greatly.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection range of the present utility model.
