[0027] Referring to Figure 1 , the present invention provides a three - layer coding switch with a pushing and dialing function, including a first knob component 1, a second knob component 2, a first coding sensor 3, a second coding sensor 4, a first transmission device 5, a second transmission device, a switch mounting bracket 7, and a third toggle switch 8;

[0031] The first coding sensor 3 is fixed on the switch mounting bracket 7 through a first sensor mounting plate 31, and the second coding sensor 4 is fixed on the switch mounting bracket 7 through a second sensor mounting plate 41.

[0032] The first knob component 1 and the second knob component 2 are respectively in clearance fit through the first limit fixing hole 12 and the second limit fixing hole 22, so that the first knob component 1 and the second knob component 2 can rotate independently relative to the switch mounting bracket 7. Through the rotational movement of the first knob component 1 and the second knob component 2, and then respectively by means of the transmission of the first transmission device 5 and the second transmission device, finally the first coding sensor 3 and the second coding sensor 4 are respectively controlled. Among them, a pushing action can also be performed on the second knob component 2, so that the second knob component 2 makes a linear movement relative to the second limit fixing hole 22, thereby driving the third toggle switch 8 to switch the switch mode and realizing the switch function of the third layer.

[0033] The first knob component 1 includes a first-layer knob 10 and a first knob rod 11. One end of the first knob rod 11 is fixed to the first-layer knob 10. The second knob component 2 includes a second-layer knob 20 and a second knob rod 21. One end of the second knob rod 21 is fixed to the second-layer knob 20. One end of the switch mounting bracket 7 is provided with a first limit fixing hole 12. The first knob rod 11 passes through the first limit fixing hole 12. The middle of the first knob rod 11 is hollow. The second knob rod 21 is disposed through the hollow middle of the first knob rod 11 in a relatively independently rotatable manner. An indented second knob mounting hole 13 is provided at the top of the first-layer knob 10.

[0034] The first knob component 1 and the second knob component 2 are coaxially arranged. The diameter of the first knob rod 11 is larger than the diameter of the second knob rod 21, and the middle of the first knob rod 11 is hollow. The second knob rod 21 passes through this middle and is in clearance fit with the first knob rod 11, so that the second knob rod 21 can rotate independently relative to the first knob rod 11, realizing the independent control of the first-layer and second-layer coding switches. And the second-layer knob 20 is disposed at the second knob mounting hole 13 at the top of the first-layer knob 10. The second-layer knob 20 is in clearance fit with the second knob mounting hole 13, and the second-layer knob 20 can rotate independently and perform axially linear movement relative to the second knob mounting hole 13.

[0035] The first transmission device 5 includes a first gear 51 and a second gear 52. The first gear 51 is sleeved on one end of the first knob rod 11 passing through the first limit fixing hole 12 and is meshed and connected with the second gear 52 sleeved on the input end of the first coding sensor 3. By rotating the first-layer knob 10 to drive the first knob rod 11 to drive the first gear 51, and the first gear 51 drives the first coding sensor 3 through the second gear 52, the connection from the manual operation of the first knob component 1 to the control of the first coding sensor 3 is realized.

[0036] The three - layer coding switch further includes a first damping component 14. The first damping component 14 includes a first tooth disc seat 15 and a first limit sleeve 16. The first limit sleeve 16 is fixed to the switch mounting bracket 7 by screws. The first tooth disc seat 15 is provided with a first clamping groove 17 along the central axis direction. The first knob rod 11 passes through the first clamping groove 17 and is clamped with the first clamping groove 17 in the radial direction around the central axis of the first knob rod 11.

[0037] The first knob rod 11 clamps the first tooth disc seat 15 and drives it to rotate. The tooth groove of the first tooth disc seat 15 cooperates with the first limit block 18 on the first limit sleeve 16. When the first tooth disc seat 15 rotates, the first limit block 18 gives a certain damping and tooth feeling to the first tooth disc seat 15, making it more operable.

[0038] The second transmission device is a coupling 6. The first end of the coupling 6 is connected to the second knob rod 21, and the second end is connected to the input end of the second coding sensor 4. At least one transmission clamping groove 61 with a certain groove depth is provided at the second end of the coupling 6. A transmission clamping bar 42 corresponding to the transmission clamping groove 61 is provided at the input end of the second coding sensor 4. The transmission clamping bar 42 on the input end of the second coding sensor 4 can perform a linear motion with a certain depth in the groove direction of the transmission clamping groove 61.

[0039] The coupling 6 is provided with two annular switch limit baffles 62 in the radial direction along the central axis. The third toggle switch 8 includes a switch base 81 and a switch operating part 82. The switch operating part 82 is clamped in the groove between the two switch limit baffles 62. The switch base 81 is fixed to the switch mounting bracket 7 through a switch mounting plate 83.

[0040] The second knob rod 21 and the second coding sensor 4 are connected through the coupling 6 to achieve synchronous transmission in the rotation direction. And through the cooperation of the transmission clamping groove 61 of the coupling 6 and the transmission clamping bar 42 at the input end of the second coding sensor 4, it can not only meet the clamping transmission in the rotation direction but also achieve a linear motion in the groove direction of the transmission clamping groove 61. When pushing the second knob component 2, the second coding sensor 4 remains stationary, and the second knob component 2 together with the coupling 6 moves towards the direction of the second coding sensor 4. At this time, it can not only maintain the synchronous transmission of the second knob component 2 and the second coding sensor 4 in the rotation direction but also perform a pushing operation. The action of the switch operating part 82 of the third toggle switch 8 is controlled through the groove between the two switch limit baffles 62 of the coupling 6 to achieve the switching of the switch mode of the third toggle switch 8.

[0041] The three - layer coding switch further includes a second damping component 23. The second damping component 23 includes a second tooth disc seat 24 and a second limit sleeve 25. The switch mounting bracket 7 further includes a second knob fixing plate 71. The second knob fixing plate 71 is clamped in the middle of the switch mounting bracket 7. A second limit fixing hole 22 is provided at the second knob fixing plate 71. A coaxial rotating block 72 that can rotate independently in the second limit fixing hole 22 is arranged in the second limit fixing hole 22. The coaxial rotating block 72 is provided with a second clamping groove 73 along the central axis direction. The second knob rod 21 passes through the second clamping groove 73 and is clamped with the second clamping groove 73 in the radial direction around the central axis of the second knob rod 21. The second limit sleeve 25 is fixed to the switch mounting bracket 7 by screws. The second tooth disc seat 24 is provided with a third clamping groove 26 along the central axis direction. The coaxial rotating block 72 passes through the third clamping groove 26 and is clamped with the third clamping groove 26 in the radial direction around the central axis of the coaxial rotating block 72. The second limit sleeve 25 is fixedly sleeved on the outer surface position of the switch mounting bracket 7 corresponding to the second tooth disc seat 24, and at least one second limit block 27 that cooperates with the tooth groove of the second tooth disc seat 24 is provided at the position corresponding to the second tooth disc seat 24.

[0042] The second knob rod 21 drives the second tooth disc seat 24 to rotate through the coaxial rotating block 72. The tooth groove of the second tooth disc seat 24 cooperates with the second limit block 27 on the second limit sleeve 25. When the second tooth disc seat 24 rotates, the second limit block 27 gives a certain damping and tooth feeling to the second tooth disc seat 24, making it more operable.

[0043] Furthermore, both the first coding sensor 3 and the second coding sensor 4 are Hall sensors. Since Hall sensors can convert the change of magnetic field into voltage signals and have no structural or electrical connection with magnets, 360° rotation in both forward and reverse directions can be achieved, which is the same as the effect of the coding switch of the real machine part that can rotate 360° in both forward and reverse directions; Hall sensors can also judge whether it is forward or reverse rotation according to the voltage change generated by the angle change, and the number of steps of rotation of the first knob component 1 and the second knob component 2 can be calculated from the difference of the voltage change.

[0044] Compared with the prior art, the present invention provides a three - layer coded switch with a push - and - toggle function, comprising a first knob component 1, a second knob component 2, a first coding sensor 3, a second coding sensor 4, a first transmission device 5, a second transmission device, a switch mounting bracket 7, and a third toggle switch 8. The first knob component 1, the second knob component 2, the first coding sensor 3, the second coding sensor 4, the first transmission device 5, the second transmission device, and the third toggle switch 8 are all fixed through the switch mounting bracket 7 to form an independent whole. The first knob component 1 drives the first coding sensor 3 through the first transmission device 5, and the second knob component 2 drives the second coding sensor 4 through the second transmission device. The second knob component 2 can also be pushed and toggled relative to the switch mounting bracket 7 and control the third toggle switch 8 to switch the switch mode. The present invention realizes three - layer coded switch control and also has a push - and - toggle function, reducing the cost of applying a three - layer coded switch with a push - and - toggle function in the field of aviation simulators, facilitating driving and processing, being able to be used independently, and improving the development efficiency of aviation simulators.
