Description

Keyboard and bridge formation thereof

Technical field

The utility model relates to a kind of keyboard, refers in particular to a kind of keyboard and bridge formation thereof.

Background technology

At present, the button of--particularly slight keyboard--mainly is made of parts such as keycap, bridge formation (being also referred to as scissor pin-joint mechanism), signal triggering component and base plates to apply to keyboard, and as the bridge formation of one of critical component, whether its structural design is reasonable, directly has influence on the quality and the use of button.

Traditional bridge formation as shown in Figure 1, it includes the outside framework 13 that an inner frame 11 and is connected to this inner frame 11, be formed with a columned rotating shaft 111 respectively in two outsides of inner frame 11, and be formed with a circular axis hole 133 respectively corresponding to rotating shaft 111 places in two side frame body 131 of outside framework 13, make axis hole 133 that the rotating shaft 111 of described inner frame 11 inserts described outside framework 13 to form axle and transfer the registration of Party membership, etc. from one unit to another and both can be relatively rotated.The bridge formation of this type structure, exist inner frame and outside framework be difficult in conjunction with and be unfavorable for the shortcoming of making, often need to adopt manual operation winding inner frame and outside framework to form bridge formation, be unfavorable for carrying out the automation assembling, cause the waste of manpower, manufacturing cost improves relatively.

Be directed to the existing defective of tradition bridge formation, people make improvements, be beneficial to the bridge formation that automation is assembled and develop, it as shown in Figure 2, include the outside framework 17 that an inner frame 15 and is connected to inner frame 15, above the axis hole 171 of outside framework 17, locate to be formed with a V-shaped structure and importing recess 173 that be connected with axis hole 171, during winding, 151 pairs of the rotating shafts of inner frame 15 are positioned at importing recess 173 places of outside framework 17, apply active force on inner frame 15 by a tool, rotating shaft 151 on it is pressed into through importing recess 173 guiding in the axis hole 171 and finishes winding, can carry out the automation assembling by a tool to a plurality of bridge formations simultaneously and reduce time and the program that the assembling bridge formation is taken.Though the bridge formation of this type structure is beneficial to the automation assembling, but, the importing recess 173 that is formed on the outside framework 17 is designed to V-structure, the approaching face of its and arranged on left and right sides is clinoplain, and cause the orientation direction poor-performing of this importing recess 173, be unfavorable for successfully the rotating shaft 151 of inner frame 15 being guided to axis hole 171 places of outside framework 17.In addition, the importing recess 173 of V-structure design has reduced outside framework 17 to a certain extent in its structural strength that imports recess 173 places, causes the distortion of this position when winding easily.
