New description: [New technical field] This creation is about a kind of computer keyboard, especially the cantilever type button constructor of a keyboard. 1 [Prior Art] According to the current notebook computer, because it has the function of being easy to carry and handle the paperwork and instant messaging, it is widely accepted by market operators and users, and the buttons of the current notebook computer keyboard are thin. Button structure 'The notebook computer keyboard is mainly connected to the key pad of the word key and the bottom plate is assembled with a bridge-type gift structure, but the thin bridge type keyboard structure of the conventional notebook computer is lightweight and The advantage of precise operation, however, the keyboard itself must be assembled with a plurality of bridge-type branch structures between the keycap and the bottom plate of the word key, and the bridge-type support structure not only takes time and labor for assembly, but also increases the height of the keyboard. It is no longer possible to achieve the performance of the ultra-thin button, that is, the bridge-type support structure of the conventional keyboard makes the ultra-thin button target extremely limited, resulting in limited and inconvenient operation of the computer keyboard. . In view of this, the creator of this case, with many years of experience in the manufacture and design of computer keyboards, actively researched and improved, and after many physical sample production and testing, and then specifically improved the above shortcomings of the conventional keyboard, and finally completed this creation. [New content] The main purpose of this creation is to solve the lack of the above-mentioned conventional keyboard, that is, it mainly aims to improve the disadvantages of the keyboard height and assembly complexity of the bridge-type support structure of the conventional keyboard, and the creation is by The cantilevered button structure of the keyboard can greatly reduce the height of the keyboard and increase the assembly efficiency of the keys, and thus become the creator of the ultra-thin button. The present invention is a keyboard cantilever type button structure, which is composed of a key cap, a word key frame, an elastic member and a film circuit board; wherein the rear end of the δH keycap is extended to have two pivots, The two sides of the keycap are extended and formed with two broadcast pieces; after the word key frame, the end of the key frame is concavely provided with two pivoting slots, and the pivoting key is pivoted to the axis of the key frame. The two end recesses δ have a retaining groove, and the cymbal can correspond to the two struts of the key cap; the elastic member corresponds to the bottom of the key cap, and the elastic member is downwardly convex. There is a touch lever, and the user can press and touch the film circuit board to generate the button signal i. The above objects and advantages of the present invention are not limited by the detailed description of the embodiments of the invention described below and the accompanying drawings. [Embodiment] With regard to the cantilever type button structure of the present keyboard, please refer to the first embodiment of FIG. 1 to FIG. 4, the keyboard of the present invention is composed of a plurality of cantilever type button structures. The cantilever type button structure is composed of a key cap 10, a word key frame 20, an elastic member 35 and a film circuit board 30. The key cap 10 is a substantially rectangular pressing member. The key end of the key cap 1〇M419146 is formed by extending a second symmetrical pivot 丨2, and two symmetrical flaps 13 are formed on the bottom surface of the two sides of the 唁 keycap 10; The rectangular hollow frame has a rectangular accommodating space 21 for correspondingly accommodating the keycap 1 〇, and a bottom surface of the character key frame is concavely provided with two symmetrical splicing grooves 22, which can be pivotally connected The keyhole 10 is symmetrically pivoted 12 so that the keycap 1 can achieve the performance of the single cantilever button, and the bottom surface of the two ends of the key frame 2 is recessed with two symmetric slots 23 , the 俾 can correspond to the two symmetrical blocking piece 13 ′ of the keycap 1 以 to make the key cap 10 Positioned in the key frame 20 in the upward direction, and then a bearing seat 25 is formed on the end surface of the key frame 2〇, and a circle is formed in the center of the receiving seat 25 The elastic member 35 is substantially conical in shape, and is correspondingly assembled on the receiving seat 25, and the top surface of the elastic member 35 corresponds to the top cymbal: the bottom surface of the keycap 10, and the elasticity A contact bar 351 is protruded downwardly from the member 35, and the touch bar is passed down through the circular hole 26 to touch the film circuit board 3, so that the key cap 1 has a pressing force. The elastic circuit resets and presses the button signal; the film circuit board 30 is a long film-like film circuit board that conducts a button signal, and the system is disposed between the word key frame 20 and a bottom plate 4〇. A conductive end 31 is disposed on the circuit board 30 corresponding to the position of the elastic member 35, and the conductive end 31 is electrically connected to the lower touch of the contact lever gw 5 M419146 of the elastic member to generate a button signal; The second embodiment of the cantilever type button structure of the present keyboard, the kiss is referred to FIG. 5 to FIG. The difference from the first embodiment is that the housing space 21a of the font frame 20a has no extension bearing structure, and the elastic member 35a is formed on a rubber gasket 34. The rubber/shield 34 is located at the bottom surface of the key frame 20a; then, the pivoting groove 22a and the groove on the key frame 20a are correspondingly assembled to the pivot of the keycap 10. 12 and the position of the flap, and a conductive end 3ι is disposed on the film circuit board 30 corresponding to the elastic member 35a, and the conductive end 31 is pressed downward by the touch lever 35u of the elastic member 35a. Touch the pass to generate the button signal. The cantilever button structure of the creation keyboard can reduce the number of parts used and reduce the assembly cost, that is, it can be lowered before the assembly of the conventional bridge support structure, and the keyboard height can be greatly reduced and the assembly of the button can be increased. Streamline performance and, in turn, achieve the construction of ultra-thin buttons. The disclosure of the above-described embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention. Therefore, changes in numerical values or substitution of equivalent elements are still within the scope of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in compliance with the provisions of the Patent Law. 6 M419146 [Simplified illustration of the drawing] Fig. 1 is an exploded perspective view showing the structure of the cantilever type button; Fig. 2 is a partial bottom perspective exploded view showing the cantilever type button structure of Fig. 1; Fig. 3 is a view showing Fig. 2 3 is a perspective sectional view of a cantilever type button structure; FIG. 4 is a perspective sectional view showing a second embodiment of the present invention; FIG. 5 is an exploded perspective view showing the second embodiment of the present invention; Combined sectional view.
