Description of the invention: [Technical field to which the invention pertains] A keyboard, in particular, a keyboard structure having an improved assembly structure to reduce the overall thickness of the keyboard. . [Prior Art] Currently used in the keyboard for computer input data, the buttons of the button module can be divided into a vertical lifting button and a bridge-linked button, wherein the vertical lifting type structure is as "the keyboard of the Republic of China Patent Publication No. 582597". As shown in the structural improvement, the entire button module is composed of a first cover plate, a second cover plate, an elastic ugly member, and a conductive component stack. It is known that the missing type of the vertical lift type is that the keyboard has A certain thickness can not be applied to compact products such as notebook computers. Therefore, most of the thin keyboards are bridge-linked, and the bridge-linked button system adopts two staggered activities (four) straight to the lion for up and down displacement, and the vertical vertical type In terms of buttons, the overall height is low, and its structure is as shown in the "National Patent Publication No. 122〇214", "Keyboard for Segmentable Lifting Buttons", which can be taken from the first, second and third figures of the prior patent. In the middle view ^ The basic structure of a button module, a button module includes a plurality of key caps, a plurality of support structures (bridge members), a substrate, a circuit film (a circuit board) And an elastic film comprising a plurality of elastomers, wherein the substrate comprises a guide plate (bridge plate connecting the bridge members) and a metal bottom plate, and the circuit film is sandwiched between the guide plate and the metal base plate, due to bridging The interlocking action line • Recording the vertical lifting type short makes the overall keyboard height significantly lower; however, when the bridge-and-bridge type keyboard is continuously reduced in thickness, it is found that the thickness of the bridge plate accounts for a large proportion of the thickness of the button module. The creation of a metal base plate is punched out of a plurality of pivoting slots for fixing the bridge member, and the metal base plate is replaced by the function of the bridge plate, such as the "keyboard key positioning structure improvement (3)" of the Republic of China Patent Publication No. 471689, The bridge plate has been omitted from the creation, and the metal base plate is directly stamped out of the splicing groove of the fixed plurality of bridge members, and the circuit film is adhered to the metal base plate, so that the button module is thinner and lighter to achieve the original research and development target; There is also a lack of replacement of the bridge plate by the metal base plate. In the past, the bridge plate was shaped like a valve, and the manufacturing cost and technical level were low, and the yield of the output was low. The cost of the _ metal base plate stamping complex rotary groove is higher than the technical level, and the yield is low. If the error of any pivoting groove of the punching multiple pivoting groove is too large, the bridge member cannot be assembled, and the entire bottom plate needs to be assembled. Abandonment can not be used, indirectly increase the average cost of each button module, and 1368894 due to ^ bridge (four), rubber, if the friction with the metal floor will make the bridge parts wear more serious t ===7_ her feet tender touch The basic form and the _ bottom plate replace the two types of bridge plates, both of which have their own advantages and disadvantages. So far, the button module has been greatly changed, the most important factor affecting the thickness of the keyboard is the thickness of the upper cover and the lower cover, and the thin button type The thickness of the keyboard is covered by the thickness of the cover and the thickness of the cover. Therefore, the upper cover and the lower cover of the keyboard are assembled to form a barrier that cannot be reduced. [Summary of the Invention]
