Description

button

The utility model relates to a key, in particular to a key whose length is a multiple of the width of the key cap.

Most of the keys on the keyboards of current computers or electronic typewriters are keys of square keycaps (KeyCap), and a small number of keys, such as space keys (SPACE), input keys (Enter), large character keys (CAPLOCK), shift keys (SHIFT), the length of the keycap is a multiple of the width, such as double or triple, and such keys are called multiple keys.

There is a balance bar in the structure of the existing multiplier key. This is because the length of the multiplier key is longer. If the balance bar is not provided, if the user presses the non-central position of the keycap, the multiplier key will be in the shape of a horizontal reference plane. tilt phenomenon. After the balance bar is installed, even if the user presses the non-central position of the key cap, the multiplier key will not be tilted. However, when assembling the keycap, the inner support arm component, the outer support arm component, the elastic component, the balance bar and the base plate, some tolerance values of each component must be provided so that each movable component can be combined smoothly. However, it is also because of the tolerance between the components, and because the balance bar is movably fitted in the groove of the hook on the base body, and the hook itself is made of hard plastic. During the pressing process of the multiplier key, the surface of the balance bar and the hook contact and collide with each other, naturally generating noise.

The purpose of the utility model is to provide a multiple button, which can significantly reduce the noise.

The purpose of this utility model is achieved by providing a key, which includes: a key cap; a switch element, which can be selectively conducted in response to the up and down movement of the key cap; a rubber film, which Placed on the switch element; a seat body, which has a pair of hooks, and the hooks and the seat body form a channel, and the seat body has an opening below the channel; a balance bar, It has a longitudinal shaft connected to two lateral sides to form an approximately Z-shaped shape, and the ends of the two lateral sides are respectively placed in the grooves corresponding to the hooks; the rubber film corresponds to the hooks and the corresponding grooves A flange is integrally formed upwardly at the center, and the flange passes through the opening and contacts with two lateral edge ends of the balance pole.

The utility model further provides a button, which includes: a key cap; a switch element, which can be selectively conducted in response to the up and down movement of the key cap; a rubber film, which is arranged on the switch element Above; a seat body, which has a pair of hooks, and the hooks and the seat body form a channel; a balance bar, which has a longitudinal shaft connected to two lateral sides to form an approximately Z-shaped shape, and the two lateral side ends Parts are respectively placed in the grooves corresponding to the hooks; horseshoe-shaped shock absorbers are arranged in the grooves corresponding to the hooks, which are in contact with the two lateral edge ends of the balance bar, and the horseshoe-shaped shock absorbers are separated from the rubber film. components.

The utility model also provides a button, which includes: a key cap; a switch element, which can be selectively conducted in response to the up and down movement of the key cap; a rubber film, which is arranged on the switch element On: a seat body, which has a pair of hooks, the hooks and the seat body form a channel, and the seat body has an opening under the channel respectively; a balance bar, which has a longitudinal shaft connection The two lateral sides are formed to form an approximately Z-shaped shape, and the ends of the two lateral sides are respectively placed in the grooves corresponding to the hooks; The flange passes through the opening and is pressed by the hook to form a horseshoe-shaped vibration absorber, which is in contact with the ends of the two lateral sides of the balance bar.

The utility model has the advantages of simple structure and low noise.

Below in conjunction with accompanying drawing, describe embodiment of the present utility model, wherein:

Fig. 4B is a cross-sectional view of the combined hook of the third embodiment of the present invention.

Please refer to FIG. 1A and FIG. 1B , the multiplier key of the present invention includes a keycap 11 , a housing 13 , an elastic element 15 , a membrane switch 18 , a balance bar 21 and a substrate 19 . As in the prior art, the utility model is provided with a rubber film 17 above the membrane switch 18, and the rubber film 17 corresponds to each keycap 11 and then upwardly forms a rubber bowl (Rubber Dome) as the elastic element 15, when the button is pressed , the rubber bowl 15 deforms downward; and when the key is released, the rubber bowl 15 provides an elastic force to push up the keycap 11 . A first pair of hooks 16 is formed on the seat body 13, and the seat body has an opening 161 respectively under the channel of the pair of hooks, and the first pair of hooks 16 are arranged corresponding to the two ends of the balance bar 21. The detailed structure As described later.

The membrane switch 18 can be selectively electrically connected in response to the up and down movement of the keycap 11 . The balance bar 21 has a longitudinal shaft portion 211 connected to two lateral sides to form a shape of a letter, and its two lateral side ends 213 are respectively inserted into the corresponding grooves of the first pair of hooks 16 of the seat body, and The longitudinal shaft portion 211 of the balance bar 21 is fitted into the pair of fitting portions 111 of the keycap. Therefore, as shown in Figure 1, the two sides corresponding to the positions of multiple keys on the base body 13 of the keyboard are respectively formed with grabs 16, and the grabs 16 are used for fitting the two side ends 213 of the balance bar 21 to prevent the balance bar from 21 break away from the seat body. When the keycap moves up and down, the longitudinal shaft portion 211 of the balance bar 21 rotates in the fitting portion 111 , and its two lateral edge portions 213 slide in the two hooks 16 .

In this utility model, a flange 14 is integrally formed upwards at the rubber film 17 corresponding to the hook 16 and the corresponding groove, as shown in Figure 2A, the flange can pass through the opening and connect with the two lateral edges of the balance bar. The ends 213 are in contact. Because the flange 14 is made of rubber material, it can absorb shock, so it can reduce the noise when the side edge 213 of the balance bar slides in the hook 16 and the two collide with each other.

That is to say, during the up and down movement of the multiplier key, the end 213 of the balance bar 21 no longer impacts the surface of the base body, which can reduce the noise by about half, as shown in the cross section of FIG. 2B .

Referring to Fig. 3 for the second embodiment of the present utility model, before assembling the balance bar 21, a horseshoe-shaped rubber body 27 can be placed and embedded in the space corresponding to the hook 16 of the multiplier key, and then the balance bar 21 can be inserted , and there is a protrusion 163 at the top of the hook 16 to fix the rubber body 27 in the hook 16; the completed section is shown in FIG. 3 . In this embodiment, the balance bar 21 only contacts and impacts with the rubber body 27 during the up and down movement of the keycap, so it can absorb most of the noise. It should be noted that in this embodiment, the rubber body 27 and the rubber film 17 are separated and not integrally formed.

The third embodiment of the present utility model is shown in Fig. 4A and Fig. 4B. When forming the rubber film 17, a flange 37 can be integrally formed in advance at the position corresponding to the hook 16, and the flange 37 is corresponding to the hook. There is a notch 371 in the direction of the groove, so that the flange 37 is easy to bend in this direction; a protrusion 163 is provided on the top of the hook 16 to fix the flange 37 in the hook 16 . In the process of assembling the seat body, the flange 37 is bent, as shown in FIG. 4B after completion. The space formed by the bent flange 37 allows the end of the balance pole 21 to pass through, as shown in FIG. 4B . Comparing Fig. 3 and Fig. 4B, it can be seen that the flange 37 and the rubber film 17 in Fig. 4B are integrally formed, which helps to simplify the production steps.
