The key structure that constitutes it. [Prior Art] The key structure currently used for a thin keyboard mainly includes a keycap, a bridge (or a scissor type linkage structure), a circuit board, a touch component, and a bottom plate (also has a bridge group = a bridge) The board is placed between the bridge board and the backplane, and the bridging mechanism technology can be divided into two major items. The advantages and disadvantages are described as follows: '-, as in US Patent No. 5278374, 555597:1 Patent No. 596,434, No. 6,482,823, which is provided with a shaft portion and a shaft rotating portion on the side bracket body of the inner frame and the outer frame. The advantage of this technique is that the inner frame and the outer frame of the bridge are pivoted. The point limit is smoother than the rotation force, but the disadvantage is that the inner frame and the outer frame are difficult to be combined and unfavorable, and if the button stroke is effectively controlled, such as the Taiwan Patent Publication No. 511772 Patent Office Show two relative bumps to achieve the limit effect. In the case of U.S. Patent No. 5,630,501, the case is characterized in that the inner and outer frames are equidistantly provided with convex portions and concave portions to be combined in a spanning manner (10) frame, and the outer frame can be directly produced. And the corresponding relationship between the convex part and the concave part can effectively control the key stroke, and the improved patent shot loss ^ Taiwan Patent Announcement No. 539m, relative to the age of the bridge is not raised 2 will have a large turning force and (9) . Position relationship 2, the above two technologies all have the same problem, when the inner frame of the bridge = inner and outer domain outer frame needs to be kept normally - when the inner and outer frames can be rotated relatively, the inner and outer frames will not touch or cause wear or The occurrence of the off-the-job event, [description of the invention], through the bridge of the present invention, the U-bridge of the machine, the U-U of the bridge, the inner and outer frames of the bridge are located at the side brackets of the interactive assembly 1273617 ^ relative mechanical (10) The shaft portion and the shaft rotating portion of the relationship are arranged on the side bracket body so as to form a constant red rising position of the button, and the secret and relative parts of the bridge are formed, thereby achieving stable relative rotation and limitation of the bridge. The effect of the button stroke. Another object of the present invention is that the connection direction of the convex portion of the fairy portion of the design of the present invention is the same as that of the bridge shaft, so that the length of the limiting protrusion from the side of the building is greater than The limit position is the degree of riding of the side bracket of the self-cultivating frame, so that the gap between the _ and the outer frame can be avoided without causing contact friction between the inner and outer frames to effectively avoid wear or breakage. [Embodiment] The present invention provides a detailed description and technical content, and the following diagram is as follows: Please read the "pictures shown in the drawings; 1, 2, and 3" as shown in the figure: the present invention is a keyboard The button box is composed of two inner frames 21 and one outer frame 22, and a bridge 2 is formed.

The bridge 2 is connected to the bridge board. The signal triggering component includes an elastic body 3 and a circuit board 6〇, if it is a single bottom plate 50 " The ten circuit boards 60 are disposed between the bottom plate 50 and the keycap 1〇. If the bridge plate 4 is designed, the road surface board 60 is disposed between the bridge board 4〇 and the bottom plate 5〇, and the elastic body 3〇 can be Single or multiple are connected to the -_ slice (mylar), but the above are all existing technologies, and the present invention is not described in the embodiment of the present invention, and will not be described again in the embodiment. The main design point of the present invention is that the bridge 2 〇 includes a limiting recess 223 and a rotating portion 224 on the two side brackets 22q of the inner frame 交互 which are alternately assembled. The side bracket body 21 of the frame 21 is provided with a limiting convex portion 213 and a shaft portion 214 opposite to the shaft rotating portion 224 with respect to the limiting recess portion 223, so that the inner frame 21 is the shaft portion 214 and the outer frame The shaft pivoting portion 224 of the shaft 22 is relatively rotatable and is relatively rotatable, and the positional protrusion 213 of the inner frame 21 is displaced in the limiting recess 223 of the outer frame 22 to define a normal rising position and pressing of the button. Down position. 6 , 1273617 (4) When the frame 21 and the outer frame 22 are combined, the restriction recess 223 and the -^ 223 ·· 孝 彳 彳 24 are inclined and tapered introduction surfaces 223 or the restriction recesses At least 234 of the 223 is a slantingly tapered introduction surface 2232 from the upper end toward the 5 ridge shaft rotation portion 224, and the introduction surface 22 is splayed, and the 杂 to the miscellaneous rotation portion 224 is a plane vertical surface 2233, so that the inner frame is The shaft portion of the limiting portion 223 may be conveniently disposed in the shaft rotating portion 224. The present invention may be designed with a leading surface 2232 (relative to the shaft) on the three sides of the limiting recess 223. The vertical side surface of the part is provided with a plane vertical surface 2233 to effectively limit the shaft portion to be hungry to form a -v-type introduction groove type, and the shaft portion 214 is stored in the introduction surface 2 to form an all-in = 2141 And - turn to 2142, and let _ 21 can be automatically corrected by the axial correction and guidance for the vertical, direction, and the shaft portion 214 is placed into the shaft torn part, the limit convex part will enter. In the limiting recess 223, the limiting protrusion 213 can provide the inner frame 21 and the outer frame 22 in addition to the button stroke.
