fig. 2 is a top view of a mechanical key according to the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more readily understand the advantages and features of the present invention, and to clearly and unequivocally define the scope of the present invention.
Referring to fig. 1 and 2, fig. 1 is a side sectional view of a mechanical key according to the present invention, and fig. 2 is a top view of the mechanical key according to the present invention. The mechanical key structure of the invention can be applied to various multimedia devices with keyboards, such as desktop computers, notebook computers, multimedia all-in-one machines and the like.
This mechanical key structure, including base 1, the axle frame 2 of setting on base 1, the axis body 3 of setting in axle frame 2, axis body 3 includes axle cap 4 and axle bed 5, be provided with spring 6 between axle bed 5 and the base 1, be provided with metal contact shell fragment 7 between axle bed 5 and the axle frame 2, metal contact shell fragment 7 triggers first key position signal under the vertical displacement drive of axle bed 5, be provided with conductive contact 8 on the base 1, conductive contact 8 includes normally open contact, normally closed contact, the internal surface of axle frame 2 is provided with at least one switch shell fragment 9 of being connected with conductive contact 8 electricity, switch shell fragment 9 triggers second key position signal under the horizontal displacement drive of axle bed 5.
In this embodiment, the inner surface of the shaft frame 2 is provided with a pair of switch elastic pieces 9 electrically connected with the conductive contacts 8, the switch elastic pieces 9 are located at two lateral sides of the shaft seat 6, and the conductive contacts 8 and the switch elastic pieces 9 are electrically connected in the shaft frame 2. Widen the direction that sets up switch shell fragment 9 in axle frame 2, reserve the spaciousness that can supply axis body 3 lateral shifting between the open-top of messenger axle frame 2 and axle bed 5. When the longitudinal displacement of the shaft seat 5 triggers the first key position signal, the switch elastic sheet 9 simultaneously triggers the second key position signal under the driving of the transverse displacement of the shaft seat 5, and the combination of the first key position signal and the second key position signal triggers the third key position signal.
The second key position signal corresponds to a paired operation instruction, the paired operation (on/off, large/small, high/low and the like) is more visual and simple, the keyboard operation functionality and the shortcut are improved, the shortcut operation without a combination mode is really realized, a large amount of shortcut key operations are simplified, and the usability of the keyboard is improved by combining a key self-defining setting function.
In another embodiment, the switch leaf 9 is positioned higher (near the end of the key cap 4) to ensure that the conductive contact 8 cannot be conducted when the key is pressed, so that the shaft seat 5 is separated from the conductive contact 8 when the shaft seat 5 is longitudinally displaced to trigger the first key position signal. Meanwhile, the switch elastic sheet 9 with a higher pressure threshold value is selected, misoperation is avoided, and the touch feedback of the longitudinal key and the transverse switch is distinguished. When the key is in an off state, a force which is the same as the deformation direction of the metal elastic sheet is applied to the key cap (the key is stirred towards the left and right directions), the shaft body applies pressure to the metal elastic sheet, the light touch switch is switched on, and related circuits are switched on. The function of a single key is increased by combining a spring switch structure, and the action mode is enriched, so that more output is given to the single key, and the keyboard function is greatly expanded under the condition of limited key positions; by separating the spring switch from the moving direction of the key, the hand feeling of the key is kept to the maximum extent, and the original appearance, principle and working effect of the key are not affected completely.
Because the metal contact spring 7 of the keyboard key is arranged at one side, the switch spring 9 is preferably arranged at the 90-degree edge of the key direction where the spring is arranged, and the influence on the contact of the key is avoided. When the key is not subjected to external force, the shaft body is kept in a disconnected state under the combined action of the spring, the metal elastic sheet, the shaft sleeve and the related fixed structure, the appearance of the key is the same as that of a common keyboard key, the elastic sheet light-touch switch has the characteristics of simple structure, long service life and clear hand feeling, and the elastic force of the elastic sheet 9 of the convex switch enables the key to return and simultaneously disconnects the contact with the conductive contact 8; when the button is pressed down, the metal elastic sheet does not receive enough pressure in the elastic deformation direction, so the metal elastic sheet keeps the fixed action on the shaft body, the button effect and the working principle are the same as those of the ordinary mechanical keyboard button, when the force of the button is greater than the elastic sheet deformation threshold value, the pressed deformation part becomes a concave shape, paragraph feedback can be obviously generated, sound is generated, and meanwhile, the elastic sheet center contacts with the conductive part, so that the whole switch is in a conduction state.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art, and all equivalent changes and modifications made according to the spirit of the present invention are included in the scope of the present invention.
