Description

Keyboard keys and their bridging

The utility model relates to a keyboard, in particular to a keyboard button and a bridge thereof. Background technique

At present, the keys applied to the keyboard, especially the thin keyboard, are mainly composed of key caps, bridges (also called scissors-type pivoting mechanisms), signal-sensing components, and base plates, and are one of the key components. Bridge bridge, its structural design is reasonable, directly affects the quality and use of the button.

A conventional bridge is shown in FIG. 1 and includes an inner frame 11 and a plurality of outer frames 13 connected to the inner frame 11. A cylindrical shaft 111 is formed at each of the outer sides of the inner frame 11, and the outer frame is formed on the outer frame. The two side frames 131 of the 13 are respectively formed with a circular shaft hole 133 at the rotating shaft 111, so that the rotating shaft 111 of the inner frame 11 is inserted into the shaft hole 133 of the outer frame 13 to form an axial relationship. The person can rotate relative to each other. Bridges of this type have the disadvantages that the inner frame and the outer frame are difficult to combine and are not conducive to fabrication. It is often necessary to manually assemble the inner frame and the outer frame to form a bridge, which is not conducive to automated assembly and waste of manpower. , manufacturing costs are relatively increased.

In view of the shortcomings of the traditional bridging, people have improved it, and developed a bridge that facilitates automated assembly, as shown in FIG. 2, including an inner frame 15 and a set of outer frames 17 connected to the inner frame 15. An introduction recess 173 having a V-shaped structure and communicating with the shaft hole 171 is formed above the shaft hole 171 of the outer frame 17, and when the assembly is assembled, the rotation shaft 151 of the inner frame 15 is opposed to the introduction recess of the outer frame 17. 173, a force is applied to the inner frame 15 by a jig, and the rotating shaft 151 thereon is guided through the introduction recess 173 and pressed into the shaft hole 171 to complete the assembly, and the plurality of jigs can be simultaneously passed through one jig. The bridge is automated and reduces the time and procedures involved in assembling the bridge. This type of structure is beneficial to the bridge The ergonomic assembly, however, the introduction recess 173 formed on the outer frame 17 is designed as a V-shaped structure, and the introduction surfaces on the left and right sides are inclined planes, resulting in poor positioning and guiding performance of the introduction recess 173. It is disadvantageous to smoothly guide the rotating shaft 151 of the inner frame 15 to the shaft hole 171 of the outer frame 17. In addition, the introduction recess 173 of the V-shaped structural design reduces the structural strength of the outer frame 17 at its introduction recess 173 to a certain extent, which is liable to cause deformation of the position when assembled. Summary of the invention

The present invention will be further described below in conjunction with the accompanying drawings and embodiments. FIG.

Referring to FIG. 3 and FIG. 4, the keyboard button disclosed in the present invention includes a bridge 10, which is composed of an inner frame 100 and an outer frame 102 which are assembled to form an axial relationship. The end assembly is attached to the lower surface of the keycap 20, and the other end is assembled to the upper surface of a bottom plate 30. A signal sensing component 40 is disposed between the keycap 20 and the bottom plate 30. The signal sensing component 40 includes an elastic body 400 and a conductive film 402 disposed under the elastic body 400. Thus, the bridge 10, the keycap 20, the bottom plate 30, and the signal-sensing assembly 40 are configured to constitute a keyboard button. In other types of keyboard keys of the prior art, a bridge plate is also disposed on the bottom plate 30, and the other end of the bridge 10 is assembled at the upper surface of the bridge plate instead of the upper surface of the bottom plate 30.

A pair of first pivoting portions 200 and a pair of second pivoting portions 202 are formed at a lower surface of the keycap 20, and a pair of third pivoting portions protruding through the conductive film 402 are formed at an upper surface of the bottom plate 30. The portion 300 and the pair of fourth pivot portions 302. A pair of first pivoting shafts 104 are formed on both sides of one end of the inner frame 100, and a pair of second pivoting shafts 106 are formed on both sides of the other end, and a pair of third pivoting shafts 108 are formed on both sides of one end of the outer frame 102, and A pair of fourth pivot shafts 110 are formed on both sides of the other end. After the inner frame 100 and the outer frame 102 are assembled into the bridge 10, the first pivoting shaft 104 and the fourth pivoting shaft 110 are respectively inserted into the second pivoting portion 202 and the first pivoting portion 200 of the keycap 20, The second pivoting shaft 106 and the third pivoting shaft 108 are respectively inserted into the third pivoting portion 300 and the fourth pivoting portion 302 of the bottom plate 30, thereby completing the group of the bridge 10 and the keycap 20 and the bottom plate 30, respectively. Pick up. The elastic body 400 is disposed on the inner frame 100, and the upper end is fixed to the lower surface of the keycap 20, and the lower end is fixed to the conductive film 402. The keycap 20 is pressed to press the elastic body 400 such that the conductive studs 404 therein contact the electrical contacts on the conductive film 402 to turn on the circuit.

As shown in FIG. 5 to FIG. 9, the bridge 10 includes an inner frame 100 and an outer frame 102. A rotating shaft 114 is formed at each of the outer sides of the inner frame 100, and correspondingly on the two side frames 116 of the outer frame 102. A shaft hole 118 is formed in each of the rotating shafts 114. An inner side of the side frame body 116 is formed with an introduction recess 120 communicating with the shaft hole 118. The two side introduction surfaces 122 and 124 of the introduction recess 120 are formed. For the convex curved surface structure, the rotating shaft 114 is inserted into the shaft hole 118 via the introduction recess 120 to form an axial rotation relationship, so that the inner frame 100 and the outer frame 102 are relatively rotatable. Introducing the side introduction surface 122 of the recess 120, The 124 is designed as a convex curved surface, which has a better positioning guiding effect than the inclined plane. Thus, when the inner frame 100 is pressed into the outer frame 102 by the jig, the rotating shaft 114 can be guided to the importing more smoothly. The junction of the recess 120 and the shaft hole 118 is pressed into the shaft hole 118 by a force applied by the jig. Further, both of the side introduction surfaces 122, 124 have a convex arc surface structure, which can improve the overall structural strength of the outer frame 102, and the low outer frame 102 (especially at the introduction recess 120) may be deformed by being pressed.

A positive introduction surface 126 which is inclined and tapered from the upper end surface toward the shaft hole 118 is formed between the side introduction surfaces 122, 124 of the introduction recess 120, and the rotation shaft 114 is formed at its lower half with a cut surface which is inclined from the inner end surface toward the inner side. 128, the arrangement of the positive introduction surface 126 and/or the cutting surface 128 can be further positioned and introduced into the shaft hole 118 to facilitate the automatic assembly of the inner frame 100 and the outer frame 102. Preferably, a vertical plane 130 is formed between the bottom edge of the positive lead-in surface 126 and the shaft hole 118, which effectively prevents the shaft 114 from coming out of the shaft hole 118.

In summary, the bridge assembly disclosed in the present invention is designed as a convex arc surface structure for the side introduction surface of the IHJ port formed on the outer frame, so that the introduction recess has a better positioning and guiding function. The rotating shaft of the inner frame is pressed into the shaft hole of the outer frame to complete the assembly of the two, and the structural strength of the outer frame (especially at the introduction notch) can be improved, and the outer frame is reduced due to the compression of the outer frame. And the possibility of deformation.
