Description

Structure and keyboard structure to prevent keys from shaking

technical field

The utility model relates to a structure for preventing keys from shaking, in particular to a structure which is simple in structure, convenient in forming, easy to manufacture and low in cost, and can reliably prevent keys from shaking. The structure is suitable for computers, mobile phones, or personal digital assistants The keyboard structure of devices such as (PDA) is particularly suitable for the button of scissors type elastic structure. The utility model also relates to a keyboard structure which can prevent keys from shaking.

Background technique

Typically, devices such as computers, mobile phones, or personal digital assistants (PDAs) have keyboards. FIG. 1 shows a key structure of a computer keyboard, which has a key 10 of a scissors-like elastic structure. Compared with traditional keys, this type of scissor key 10 has been widely used in thin keyboards, especially notebook computer keyboards in recent years due to its advantages of long key travel, average force, and low noise decibels. The button 10 is arranged on the substrate 20, and the button is composed of a first arm 11 pivotally connected to the pivot shaft 13 in the shape of "ㄩ" and a second arm 12 arranged in the first arm 11. The first arm Positioning arms 111 are provided on both sides of the arm 11 respectively, and the positioning arms pass through the positioning pieces 21 provided at corresponding positions of the base plate 20 . Since most of the material of the substrate 20 is metal, the positioning piece 21 can be stamped from the substrate 20 , as shown in FIGS. 2A and 2B . The positioning piece 21 has a hole 211 , and the positioning arm 111 passes through the hole. The key 10 has a reciprocating direction F perpendicular to the substrate 20. When the key 10 is not pressed, the first arm 11 and the second arm 12 appear on the substrate 20 by means of elastic members (not shown in the figure). The dotted line in 2B shows a scissors-like upturned state. After the button 10 is pressed, the first arm 11 and the second arm 12 can be flatly pressed on the substrate 20 . In order to make the button 10 operate smoothly, the hole 211 and the positioning arm 111 have a certain gap D and are loosely fitted. In addition, the allowable error of the forming size of the positioning piece 21, the distance between the two positioning pieces 21, and the matching size with the first arm 11, together with the existence of the gap D, cause the key 10 to be displaced and Shaking, thus affecting the stability of the overall key when pressed, and may cause the key to lose its function due to inaccurate pressing position.

Of course, the invention is not limited to the enumerated embodiments.

Please refer to FIG. 3 , FIG. 4A and FIG. 4B . The base plate 30 is provided with a button 10 of a scissors-type elastic structure, which is the same as the existing structure. The button 10 is composed of a first arm 11 that is pivotally connected to the pivot shaft 13 and is arranged in the first arm 11. The second arm 12 constitutes. There is a positioning arm 111 on both sides of the first arm 11, and the positioning arm is installed in the positioning piece 31 provided at the corresponding position of the substrate 30. Since the material of the substrate 30 is mostly metal material, the positioning piece 31 It can be stamped and formed from the substrate 30 . As shown in FIG. 4B , the positioning piece 31 has a hole 311 , and the positioning arm 111 passes through the hole. The key 10 has a reciprocating direction F perpendicular to the substrate 30 .

As far as the structure of the embodiment shown in the figure is concerned, these limiting mechanisms 32 are arranged on both sides of the first support arm 11, so as to meet the requirement that when the first support arm 11 rises to the highest position, it can still be blocked by the first support arm 11. One arm 11 side is as the criterion. In addition, the material and molding method of the limiting mechanism 32 can be determined according to the material of the substrate 30. Since most of the substrates 30 are made of metal materials, the limiting mechanism 32 can be integrally stamped and formed with the substrate 30, and can make the limiting mechanism 32 There is a loose fit between the mechanism and the button 10 .
