In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

As shown in FIG. 1 to FIG. 10 , this embodiment provides a rotary switch, which includes an integrated seat 1 , a button assembly 2 , a through-beam sensor 3 and a rotary knob assembly 4 .

As shown in Fig. 2, a push switch 13 is provided on the integrated seat 1. Specifically, the user's operation on the knob assembly 4 and the button assembly 2 is ultimately input to related equipment such as an elevator through the triggering of the push switch 13. In this embodiment, the push switch 13 is a micro switch or a point switch.

As shown in Fig. 2, the button assembly 2 is connected to the integrated seat 1, and the button assembly 2 can slide relative to the integrated seat 1 to press or move away from the push switch 13. In other words, the action of triggering the push switch 13 is to slide the button assembly 2 to press the push switch 13, which is simple to operate and easy to implement.

As shown in FIG4 , at least two through-beam sensors 3 are provided, and all through-beam sensors 3 are arranged on the integrated seat 1 at intervals along the circumferential direction, and each through-beam sensor 3 includes a transmitting end and a receiving end arranged oppositely. The knob assembly 4 includes a knob housing 41 and a plurality of light shielding parts 42, and the knob housing 41 is rotatably sleeved outside the button assembly 2, and the plurality of light shielding parts 42 are arranged on the knob housing 41 at intervals along the circumferential direction, and one of the transmitting end and the receiving end is located on the inner circumference side of the light shielding part 42, and the other is located on the outer circumference side of the light shielding part 42, and the rotation of the knob housing 41 can drive all the light shielding parts 42 to rotate, so as to block or conduct each through-beam sensor 3. In other words, the user can adjust the position of each light shielding part 42 by rotating the knob housing 41, thereby changing the state combination of each through-beam sensor 3, so that each through-beam sensor 3 is either conducted or blocked.

The knob switch provided in this embodiment has at least two through-beam sensors 3 arranged along the circumferential direction, and a plurality of shading portions 42 arranged along the circumferential direction. The shading portions 42 in different areas block or conduct the through-beam sensors 3 at corresponding positions, so that the state combination of at least two through-beam sensors 3 changes. The computer program can determine the rotation direction of the knob housing 41 by using the change in the state combination. After the knob housing 41 is rotated to the desired position, the button assembly 2 is pressed to press the push switch 13, and the user completes the operation input.

In this embodiment, two through-beam sensors 3 are provided, and the two through-beam sensors 3 can realize the identification of the rotation direction, with fewer parts, compact structure and low cost. The through-beam sensor 3 can be an infrared through-beam tube.

Optionally, the knob housing 41 has N gears in the circumferential direction, each gear has a corresponding gear center angle K=360°/N, the center angle of two circumferentially adjacent shading portions 42 is M, the center angle of two circumferentially adjacent beam sensors 3 is C=K+nM, (n is an integer, and n≥0), the center angle of the light-transmitting notch 43 between circumferentially adjacent shading portions 42 is 360°/N, and the center angle of the shading portion 42 is 720°/N. With such a configuration, each time the user rotates a gear, the state combination of the two beam sensors 3 will change, thereby facilitating the computer program to identify the change in the gear according to the change in the state combination of the two beam sensors 3, that is, the identification of the rotation angle.

Exemplarily, the knob housing 41 has 18 gears, the center angle of each gear is 20°, the center angle of the light-transmitting notch 43 between adjacent shading parts 42 is 20°, the center angle of the shading part 42 is 40°, and the center angle C of two adjacent opposing beam sensors 3 is 20°+n60°. For ease of description, the two opposing beam sensors 3 are named as the first opposing beam sensor 3 and the second opposing beam sensor 3, respectively. In FIGS. 8-10, No. 1 is the first opposing beam sensor 3, and No. 2 is the second opposing beam sensor 3. Under the setting of the above-mentioned center angles, the first opposing beam sensor 3 and the second opposing beam sensor 3 have only three initial state combinations, and these three initial state combinations include: the first opposing beam sensor 3 and the second opposing beam sensor 3 are both disconnected (disconnected-disconnected), the first opposing beam sensor 3 is disconnected and the second opposing beam sensor 3 is turned on (disconnected-turned on), and the first opposing beam sensor 3 is turned on and the second opposing beam sensor 3 is disconnected (turned on-disconnected).

As shown in FIG8, with "off-off" as the initial state combination, one gear is rotated clockwise to reach the "on-off" state combination, and one gear is rotated counterclockwise to reach the "off-on" state combination; as shown in FIG9, with "on-off" as the initial state combination, one gear is rotated clockwise to reach the "off-on" state combination, and one gear is rotated counterclockwise to reach the "off-off" state combination; as shown in FIG10, with "off-on" as the initial state combination, one gear is rotated clockwise to reach the "off-off" state combination, and one gear is rotated counterclockwise to reach the "on-off" state combination. With the above three initial state combinations, continue to rotate 2 gears or even more gears, the state combination of the two opposing sensors 3 after rotation still switches regularly between the three state combinations. Based on this rule, the corresponding state combinations under 18 gears and the relationship between the state combinations can be obtained. Specifically, in this solution, no matter what initial state combination the two opposing beam sensors 3 are in, after the knob housing 41 rotates 60°, the two opposing beam sensors 3 return to the initial state combination, thereby facilitating statistical identification of the state combinations under 18 gears.

Regardless of the initial state combination, whether it is clockwise rotation or counterclockwise rotation, as long as the rotation reaches a gear, at least one of the opposing sensors 3 will have a state change, and the state combination of the two opposing sensors 3 will change. The computer program can judge that the gear has changed. Because the changes in the state combination after clockwise rotation and counterclockwise rotation are also different, the computer program can judge the rotation direction. The computer program can judge the rotation direction and the number of rotation gears by comparing and identifying the switching of the two opposing sensors 3 between the three state combinations. Take the application of the knob switch in the elevator as an example. After the rotation direction and the number of rotation gears are determined, the target floor compared to the floor is determined. When the user operates, the knob housing 41 is rotated, and the target floor can be synchronously displayed on the digital display unit of the elevator. Pressing the button assembly 2 triggers the press switch 13, which sends an execution instruction to the elevator.

As shown in FIG3 , optionally, the outer periphery of the button assembly 2 is provided with a plurality of gear protrusions 2121 arranged in the circumferential direction, and there are gear grooves 2122 between adjacent gear protrusions 2121. A plurality of elastic abutting members 5 are evenly provided in the circumferential direction on the knob housing 41, and the elastic abutting members 5 abut against the gear grooves 2122 opposite thereto. The cooperation between the elastic abutting members 5 and the gear grooves 2122 can maintain the relative position of the knob housing 41 and the button assembly 2, so that the two opposing sensors 3 have a stable state combination after the user's operation, which is convenient for judging the rotation direction and the rotation gear. In addition, the elastic abutting member 5 is driven to move during the rotation of the knob housing 41, and the elastic abutting member 5 abuts against the outside of the button assembly 2 and slides relatively. The elastic abutting member 5 slides over the gear protrusions 2121 and switches to abut against different gear grooves 2122, which also provides the user with a shifting feel.

As shown in FIG6 , preferably, the surface of the gear protrusion 2121 is in a smooth arc shape to avoid rotation jamming. In the present embodiment, consistent with the number of gears, 18 gear protrusions 2121 are provided to form 18 gear grooves 2122. The central angle between the circumferentially adjacent elastic abutments 5 is a multiple of the central angle of the gear, ensuring that the elastic abutments 5 of each gear are abutted in the gear groove 2122. Exemplarily, when the central angle of the gear is 20°, four elastic abutments 5 are provided, and the central angle between adjacent elastic abutments 5 is 80° or 100°. As shown in FIG3 , preferably, these elastic abutments 5 are arranged in a centrally symmetrical manner in the circumferential direction to achieve force balance and keep the knob housing 41 and the button assembly 2 at the same axis.

As shown in Figures 1, 2, 3 and 7, optionally, the knob housing 41 includes a first housing 411 and a second housing 412 connected to each other.

The elastic abutment member 5 is arranged in the corresponding receiving groove 413 and extends out of the receiving groove 413 to abut against the gear groove 2122 opposite thereto.
