Description

Input device linkage component

The invention provides a linkage component of an input device, in particular a linkage component that can be installed on a circuit module of an input device and a button unit, such that the first link and the second link can be inside and outside. Cross-span, for the relative displacement of the top button unit to rise and fall, and has a simple structure, simple and quick assembly, and can achieve mass production, reduce the cost of production and assembly.

According to the continuous research and development and innovation of computer equipment and related peripheral electronic devices, more and more practical and functional electronic devices are available in the market today, and most of the input electronic devices need to pass through. Press the button to input text, numbers or commands, such as mouse, keyboard or joystick for game play, light gun and other related peripheral devices with output/input control interface, so the design of the keyboard also follows this trend. Rapid development, and change for different needs, for example, the keys used on the keyboard of the early desktop computer to the keys used for the notebook computer, the difference is quite large, mainly due to the notebook type The computer is designed to be light, thin, short, and small, so the buttons used cannot be the same as the buttons on the desktop keyboard, but must be different for the notebook. Demand changes.

The button structure used in the traditional keyboard is mainly for the assembly of the button and the bottom plate, and the interlocking component for the upper and lower reciprocating displacement actions, and the interlocking component can be roughly divided into a cross-link (screw-foot) type and a rotary joint. A shaft or chute type device that can hold the button up or down. If the cross link (scissors) is used as an example, please refer to the ninth figure, which is a stereo exploded view of the conventional one. It can be seen that each of the key bases on the keyboard substrate has a interlocking component A which is interlaced with the inner connecting rod A1 and the outer connecting rod A2, and is used to support the upper key cap B and interlaced with each other. The interlaced portion between the inner and outer connecting rods A1 and A2 is pivotally connected with a rotating shaft A11 and a shaft hole A21, and the contact portions between the inner and outer connecting rods A1 and A2 and the key cap B and the base plate C are respectively directly provided. The sliding shafts A12 and A22 and the shaft bases B1 and C1 are engaged. When the keycap B is pressed, the key caps B can be provided by the inner and outer connecting rods A1 and A2. Reciprocating displacement action, and triggering the corresponding switch electrical contact on the circuit board D with the elastic body D1 at the bottom of the key cap B, or After the keycap B is released, the keycap B is rebounded to the original position by the elastic body D1, thereby achieving the purpose of signal-triggered conduction.

However, the combination of the connecting rod A1 and the outer connecting rod A2 of the conventional interlocking component A is such that the rotating shaft A11 of the inner connecting rod A1 is inserted into the shaft hole A21 of the outer connecting rod A2 to form a movable pivot joint. If the force applied during manual assembly is too large, or if the user repeatedly presses under the keycap B for a long time, the rotation axis A11 of the inner connecting rod A1 is liable to cause stress concentration at the joint, which may easily cause cracks or breakage. In the process of assembly, the alignment between the rotating shaft A11 and the shaft hole A21 also needs to be very precise, otherwise the gap matching may be poor, and the inconvenience and difficulty of assembly may be increased due to the incorrect insertion of the size, or It is easy to loosen and slide open due to instability during installation, so that the cost of overall production and processing is relatively increased. Therefore, there is still room for improvement in the use of the room.

Therefore, in view of the above-mentioned deficiencies and shortcomings of the above-mentioned practices, the inventors have collected relevant information through multi-party assessments and considerations, and have been designing such displacements to be smooth and reliable through continuous trials and revisions through years of experience in the industry. Moreover, the cross-over-span method can be used to make the linkage component of the input device which is more convenient to assemble, and the birth of the invention patent.

The main purpose of the present invention is to provide a linkage assembly between the circuit module and the button unit, such that the first link and the second link cross each other in an inner and outer direction for relative displacement to be formed on the button unit.
