detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 , the keyboard with movable keys of the present invention includes a keyboard case 2 , a slide chute 3 , a movable key 4 , a sealing bar 6 , a sealing bar rotating shaft 5 and a key chassis slideway 17 .

The keys are set in the keyboard shell, and the sealing bar is set on the side of the keyboard. The sealing bar is connected to the keyboard through the sealing bar rotating shaft. When using this keyboard, the keyboard sealing bar is first opened, and the keys are passed through the key chassis slideway and the sliding sheet Move the chute to the position you want to move, and when all the keys have been moved, block the seal to prevent the keys from slipping out of the keyboard case.

In the present invention, an adapter including all key value information on the keyboard is provided on the keyboard substrate under each key, and a contact block corresponding to the corresponding key value information on the adapter is provided at the bottom of each key.

Embodiment one:

In this embodiment, the adapter can be configured as a key-value circuit. The circuit structure of each adapter is the same, and there are pressure-touch switches with the same number of movable keys. Each pressure-touch switch corresponds to a key value. The contact block provided at the bottom of each button can be configured as a pressing block, which corresponds to the position of the pressing switch that outputs the corresponding key value, and is used to press the corresponding pressing switch to make it connected. When a key is pressed, the pressing block at the bottom of the key will touch the pressing switch at the corresponding position, so that the corresponding pressing switch is turned on, and the corresponding key value is output.

As shown in Fig. 2, the keyboard of this embodiment is provided with 50 keys, and the adapter below each key is provided with 50 pressure-touch switches, 1K1, 1K2, 1K3, ..., 1K50 are located under the first key. A pressure-touch switch on an adapter, 2K1, 2K2, 2K3, ..., 2K50 is a pressure-touch switch on an adapter under the second button, ..., 50K1, 50K2, 50K3, ..., 50K50 is The 50th button is set on the pressure-touch switch on an adapter, and 50 pressure-touch switches under each button are connected in parallel. There are 50 buttons in this embodiment. Therefore, the keyboard circuit in this embodiment consists of 50 groups of such pressure-touch switches, when a certain pressure-touch switch on an adapter is touched by the pressure-touch block of a button, the corresponding pressure-touch switch will be turned on, and a corresponding key value will be output .

As shown in Figure 3, the position of the pressure-contact block corresponding to the pressure-contact switch on the adapter under the mobile button is shown. The black-painted pressure-contact block in Figure 3 is a pressure-contact block set under a certain key. Corresponding to the pressure-contact switch 1K1 or 2K1 or 3K1 or...or 50K1, that is, corresponding to the position of the pressure-contact switch in row 1 and column 1 on each adapter, when the button where the pressure-contact block is located is pressed , no matter which position the key moves to on the keyboard, as long as the key is pressed, the pressure-contact switch corresponding to row 1 and column 1 on the adapter is turned on, and the output is the same key value.

Embodiment two:

As shown in Figure 4, the difference between the second embodiment and the first embodiment is that the key-value circuit of this embodiment includes an A/D conversion circuit, a set of pressure-contact switches, and each pressure-contact switch is connected in series with a resistor. The resistors of the resistance value correspond to the pressure-touch switches of different key values. In this embodiment, every 10 pressure-touch switches form a group, and are connected to an input and output port of the single-chip microcomputer through the A/D conversion circuit. There are 50 buttons in total. Need 5 single-chip input and output ports. Table 1 shows the resistance values of the corresponding resistors in the 10 key-value circuits, and Table 2 shows the output voltage of each press-touch button in the 10 key-value circuits when it is pressed. It can be seen from Table 2 that when different buttons are closed, the value of Vad is also different. According to the principle of A/D conversion, the corresponding digital quantity after conversion is also different; conversely, according to the digital quantity after A/D conversion, you can Know which button is closed. In other embodiments, the number of pressure-contact switches in each group can be adjusted, and the input and output ports of the single-chip microcomputer can be adjusted accordingly.

As shown in Figure 3, assuming that the pressure-contact block corresponding to the pressure-contact block in the first row and the first column is turned on, the output key value is 'A', then the first row and the first column under each button correspond to When the push-touch switch is turned on, the output key value is 'A'. If a button is provided with a push-contact block at the position corresponding to the push-touch switch in row 1, column 1, no matter where the button moves to Which position of the keyboard, as long as the key is pressed, it will be in contact with the pressure-touch switch on the first row and the first column of the adapter under the key, the key-value circuit is turned on, and then according to its A/D value and I/O The interface is used to determine which button is pressed, so as to obtain its key value, and the principle of other key value output is the same.

Table 1 Corresponding resistance value of each resistor

Table 2 Vad voltage value when each button is closed

In addition to the way that the key-value circuit can use the combination of the pressure-touch block and the pressure-touch switch in Embodiment 1 and Embodiment 2, in other embodiments, the key-value circuit can also use a set of contacts containing all key-value information Composition, a metal contact is set at the bottom of each button, and the metal contact uniquely corresponds to the position of the corresponding contact. When no button is pressed, the contact of the key-value circuit is disconnected. When a button is pressed, the button The metal contact at the bottom is just in contact with the contact below, so that the circuit is turned on and the corresponding key value is output. And according to actual needs, the number of keys on the keyboard can be increased or decreased accordingly.

The key of the present invention comprises a keycap, the contact block is connected under the keycap, and the keycap is floating and detachably connected to the keyboard substrate. The floating connection method of the key can refer to the connection method of the existing keyboard, it only needs to be guaranteed to be detachable.

The specific implementation of this embodiment is shown in Figure 5. The key also includes a key chassis 9 erected on the keyboard substrate. A slide 14 is provided on the side of the keycap 7, and a slide 14 is fixedly connected to the bottom of the slide for connecting the touch pad. The continuous piece 11 of block, the position of continuous piece is lower than the button chassis. The floating connection method of this embodiment adopts scissors feet 8 and airbags 10, and the scissors feet and airbags are arranged between the key cap and the key chassis. In Fig. 5, 20 is an adapter arranged on the keyboard substrate, and 3 is the cooperation between the keyboard and the slide plate 17 is the slideway of the key chassis on the keyboard. When the key is pressed, the airbag is compressed, the slide is pressed down, and the corresponding contact block on the bottom of the slide contacts the adapter to make the corresponding pressure touch The push-touch switch or contact is connected to realize the function of the corresponding button. When the user lets go, the button is bounced to the original position due to the rebound of the airbag, so that the contact block leaves the adapter, and the corresponding press-touch switch or contact is disconnected.
