[0002] At present, almost all keyboard knob switches on the market are electronic knob type, which realizes the disconnection or conduction of signals by using metal sheet contact. In the process of contact between metal sheets, arcs are easily generated between metal sheets to oxidize the metal surface. At the same time, long-term contact and friction also cause wear on the surface of the metal sheet, resulting in a short service life of the keyboard knob switch. The keyboard switch is usually installed in the upper right area of ​​the keyboard. When the keyboard needs to be used and turned off or the keyboard mode is switched, the keyboard knob switch is twisted to operate. Since the keyboard switch needs to be used frequently, the service life of the electronic knob switch is generally 25,000 times, which cannot meet the use needs of some consumers. If a keyboard knob switch with a simple structure and a long service life can be designed, the above problems can be well solved. Summary of the invention

[0016] Embodiment 1:

[0017] like Figures 1 to 3As shown, in this embodiment, the utility model includes a knob 1, a cover 2, a Hall magnet 3, a Hall sensor 4 and an automatic locking component 5, the upper end of the knob 1 is movably matched with the cover 2, the Hall sensor 4 is fixed on the cover 2, the Hall magnet 3 is fixed on the knob 1 and cooperates with the Hall sensor 4, and the automatic locking component 5 locks the knob 1. As can be seen from the above scheme, the knob switch includes the cover 2 and the knob 1 that are movably matched with each other, the Hall sensor 4 is fixed on the cover 2, and the Hall magnet 3 is fixed on the knob 1. When the knob 1 rotates, the Hall magnet 3 is driven to approach or move away from the Hall sensor 4, so that this keyboard knob switch can achieve a switching effect. Therefore. The utility model is not only simple in structure, but also compared with the traditional metal sheet keyboard knob switch, the utility model uses a keyboard knob switch containing a Hall sensor 4 and a Hall magnet 3, so for the keyboard knob switch, the accuracy of the switch can be improved, and at the same time, the service life of the keyboard knob switch is also extended.

[0018] In this embodiment, the knob 1 is provided with two limit blocks 6, and the cover body 2 is provided with two ribs 7. The two limit blocks 6 cooperate with the two ribs 7 respectively. When one of the limit blocks 6 cooperates with the rib 7 on the same side, there is a crisp sound of "pa pa", and the Hall magnet 3 triggers the Hall sensor 4. When the other limit block 6 cooperates with the rib 7 on the same side, there is a crisp sound of "pa pa", and the Hall magnet 3 is away from the Hall sensor 4. It can be seen that when the keyboard knob switch reaches the open or closed position during the rotation process, a crisp sound of "pa pa pa" can be emitted, which can serve as a reminder to the user.

[0019] In this embodiment, a fixing seat 8 is fixedly connected to the cover body 2, and the keyboard knob switch further includes a bearing 9. The cover body 2 cooperates with the fixing seat 8 to fix the bearing 9, and the lower end of the knob 1 is connected to the inner ring of the bearing 9. It can be seen that the bearing 9 fixed by the fixing seat 8 between the knob 1 and the cover body 2 cooperates with each other, and the knob 1 and the cover body 2 can reduce wear when they cooperate with each other, further improving the service life of the keyboard knob switch.

[0020] In this embodiment, the automatic locking assembly 5 includes a locking magnet 51 and an adsorbing iron sheet 52, and the adsorbing iron sheet 52 has two pieces respectively arranged on the fixing seat 8. It can be seen that when the limit block 6 of the knob 1 and the ribs 7 in the cover body 2 are mutually limited and matched, the locking magnet 51 and the adsorbing iron sheet 52 cooperate with each other under the action of magnetic force to play a locking role. Because the force of the user turning the knob each time is different, when the rotation force is not strong enough, the locking magnet 51 and the adsorbing iron sheet 52 can play an auxiliary role when the knob reaches the open or closed position under the action of magnetic force.

[0021] In this embodiment, the working principle of the utility model is as follows:

[0022] like Figure 2 As shown, when the keyboard knob switch needs to be turned on, first twist the knob 1 90° clockwise. During this process, the limit block 6, the Hall magnet 3 and the locking magnet 51 are close to the Hall sensor 4. When one of the limit blocks 6 is limited by the ribs 7 on the same side of the cover body 2 and a crisp sound is emitted, and at the same time, the locking magnet 51 and the adsorption iron sheet 52 are limited by each other, the Hall magnet 3 triggers the Hall sensor 4, and the Hall sensor 4 receives a signal, and the keyboard knob switch is in the on state.

[0023] like Figure 3 As shown, when the keyboard knob switch needs to be turned off, first twist the knob 1 counterclockwise by 90°. During this process, the limit block 6, the Hall magnet 3 and the locking magnet 51 are away from the Hall sensor 4. When the other limit block 6 is limited by the ribs 7 on the same side of the cover body 2 and a crisp sound is emitted, the locking magnet 51 and the adsorption iron sheet 52 are limited by each other, the Hall magnet 3 is away from the Hall sensor 4, the Hall sensor 4 will not receive a signal, and the keyboard knob switch is in the closed state.

[0024] Embodiment 2:

[0026] The knob 1 is provided with two limit blocks 6 , and the cover body 2 is provided with one rib 7 .

[0027] In this embodiment, the working principle of the utility model is as follows:

[0028] When it is necessary to turn on the keyboard knob switch, first twist the knob 1 180° clockwise. During this process, the limit block 6, the Hall magnet 3 and the locking magnet 51 are close to the Hall sensor 4. When one of the limit blocks 6 is limited and matched with the ribs 7 of the cover body 2, and a crisp sound is emitted, and at the same time, the locking magnet 51 and the adsorption iron sheet 52 are limited and matched with each other, the Hall magnet 3 triggers the Hall sensor 4, and the Hall sensor 4 receives a signal, and the keyboard knob switch is in the on state.

[0029] When the keyboard knob switch needs to be turned off, first twist the knob 1 counterclockwise by 180°. During this process, the limit block 6, the Hall magnet 3 and the locking magnet 51 are away from the Hall sensor 4. When the other limit block 6 is limited by the ribs 7 of the cover body 2 and a crisp sound is emitted, the locking magnet 51 and the adsorption iron sheet 52 are limited by each other, the Hall magnet 3 is away from the Hall sensor 4, the Hall sensor 4 will not receive a signal, and the keyboard knob switch is in the off state.

[0030] Embodiment three:

[0031] The difference between this embodiment and the first embodiment is that:

[0032] The knob 1 is provided with one limit block 6, and the cover body 2 is provided with two ribs 7.

[0033] In this embodiment, the working principle of the utility model is as follows:

[0034] When the keyboard knob switch needs to be turned on, first twist the knob 1 180° clockwise. During this process, the limit block 6, the Hall magnet 3 and the locking magnet 51 are close to the Hall sensor 4. When the limit block 6 is limited and matched with one of the ribs 7 of the cover body 2, and a crisp sound of "pa pa", and at the same time, the locking magnet 51 and the adsorption iron sheet 52 are limited and matched with each other, the Hall magnet 3 triggers the Hall sensor 4, and the Hall sensor 4 receives a signal, the keyboard knob switch is in the on state.

[0035] When the keyboard knob switch needs to be turned off, first twist the knob 1 counterclockwise by 180°. During this process, the limit block 6, the Hall magnet 3 and the locking magnet 51 are away from the Hall sensor 4. When the limit block 6 is limited by the ribs 7 of the other cover body 2 and a crisp sound is emitted, the locking magnet 51 and the adsorption iron sheet 52 are limited by each other, the Hall magnet 3 is away from the Hall sensor 4, the Hall sensor 4 will not receive a signal, and the keyboard knob switch is in the closed state.
