[0030] Please see Figures 1 to 11 A hollow encoder with a push-button switch function, comprising:

[0031] The switch body 10 includes a base 101 and a hollow shaft 102 mounted on the base 101.

[0032] Rotating shaft 20 is movably sleeved on the outside of hollow shaft 102 so that rotating shaft 20 can rotate relative to hollow shaft 102 and move along its axial direction;

[0033] The pressing plate 30 is movably sleeved on the outside of the hollow shaft 102 and located below the rotating shaft 20, so that when the rotating shaft 20 moves toward the pressing plate 30 along the axial direction of the hollow shaft 102, it drives the pressing plate 30 to move toward the base 101.

[0034] The switch signal output component includes a plurality of silicone buttons 401 evenly distributed between the press plate 30 and the base 101 for being pressed when the press plate 30 moves toward the base 101, and a signal contact 402 mounted on the base 101 and corresponding to the plurality of silicone buttons 401 for transmitting signals when the silicone buttons 401 are pressed.

[0035] Specifically, in this embodiment, during operation, when a start / stop signal needs to be transmitted externally via the switch encoder, the rotating shaft 20 is pressed, causing it to move relative to the axis of the hollow shaft 102 towards the pressing plate 30. This moves the pressing plate 30 to press the silicone button 401, thereby transmitting a signal externally through the signal contact 402. In this embodiment, this signal is a start / stop signal, allowing an external control device to start or stop the corresponding control equipment upon receiving the signal. After pressing, the pressing plate 30 and the rotating shaft 20 reset under the elastic reset of the silicone button 401, thus completing one pressing operation. Furthermore, in this embodiment, since multiple silicone buttons 401 are evenly arranged below the pressing plate 30, the force is balanced when the pressing plate 30 presses the silicone buttons 401, thereby improving the structural stability and making it suitable for industrial applications. Further, in this embodiment, the base 101 is equipped with a first terminal 103 connected to the signal contact 402 for transmitting signals externally.

[0036] The hollow encoder with a push-button switch function involved in this utility model, through the arrangement of switch body 10, rotating shaft 20, pressing plate 30 and switch signal output component, enables the switch encoder to have a switch indication function, and when pressed by using rotating shaft 20, the force is balanced, the structure is stable, suitable for industrial applications, and greatly improves the user experience.

[0037] In one specific embodiment, three silicone buttons 401 are evenly distributed between the pressing plate 30 and the base 101. In this embodiment, the evenly distributed three silicone buttons 401 can effectively improve the stability when the pressing plate 30 is pressed.

[0038] In one specific embodiment, it also includes a follower unit and an encoder body 50; the follower unit is installed above the pressing plate 30 and connected to the rotating shaft 20, and is used to rotate with the rotating shaft 20; the encoder body 50 is installed on the base 101 and located below the follower unit, and is used to cooperate with the follower unit to form an encoded signal when the follower unit rotates, and output it to the outside. Specifically, in this embodiment, during operation, the rotating shaft 20 is rotated, thereby driving the follower unit to rotate. The follower unit generates an encoded signal with the encoder body 50 during rotation, which is then output externally through the encoder body 50. This encoded signal represents the rotation amount of the follower unit. By adjusting the rotation amount of the follower unit through the rotating shaft 20, a preset encoded signal is output, effectively adjusting the setting value of the external device connected to the switch encoder. This setting value can be a volume level, pressure level, or other controllable setting value based on the rotation amount. Furthermore, a display screen can be integrated inside the hollow shaft 102. The user can switch the currently controlled setting value type by referring to the display screen, such as switching from volume adjustment to pressure adjustment, and then adjust the size of the currently selected setting value by rotating the rotating shaft 20, so that the device can be used simultaneously for adjusting multiple different types of setting values.

[0039] In one specific embodiment, the follower unit includes a wave plate 601 and a brush 602. The wave plate 601 is mounted above the encoder body 50 and connected to the rotating shaft 20, and is used to rotate with the rotating shaft 20. The brush 602 is mounted between the encoder body 50 and the wave plate 601 and is connected to the wave plate 601, and is used to rotate with the wave plate 601. The brush 602 has a 6021 that elastically abuts against the encoder body 50, and is used to cooperate with the wave plate 601 to generate an encoding signal when rotating with the wave plate 601. Specifically, the encoder body 50 is provided with an encoder chip 502 that cooperates with the 6021 to generate an encoding signal, and a second terminal 501 connected to the encoder chip 502 for outputting the encoding signal externally.

[0040] In one specific embodiment, the oscillating disk 601 is sleeved on the outside of the rotating shaft 20, and the side of the oscillating disk 601 that is in contact with the rotating shaft 20 is provided with a guide groove 6012 that is parallel to the axial direction of the rotating shaft 20; the outside of the rotating shaft 20 is provided with a guide block 201 installed in the guide groove 6012. In this embodiment, the guide groove 6012 and guide block 201 are designed to ensure that the undulating disk 601 rotates when the rotating shaft 20 rotates. Furthermore, since the guide groove 6012 is parallel to the axis of the rotating shaft 20, when the rotating shaft 20 is pressed to move towards the pressing plate 30 (i.e., along the axis of the rotating shaft 20), the guide block 201 can move relative to it within the guide groove 6012. This allows the rotating shaft 20 to drive the undulating disk 601 to rotate without affecting its stability during pressing. This ensures that the adjustment of the undulating disk 601's rotation during the rotation of the rotating shaft 20 and the movement of the pressing plate 30 during pressing do not interfere with each other, guaranteeing the rationality and stability of the structure.

[0041] In one specific embodiment, a positioning component is also included; the positioning component includes a bracket 701, a spring 702, and a ball 703; the bracket 701 is mounted above the wave plate 601 and is attached to the upper part of the encoder body 50; the upper part of the wave plate 601 is provided with a plurality of positioning teeth 6011 along the rotation direction of the wave plate 601; the spring 702 is mounted on the bottom of the bracket 701, and the spring 702 is provided with an elastic part 7021 that bends toward the wave plate 601; the ball 703 is movably mounted on the elastic part 7021 and abuts against the upper part of the wave plate 601, so that the ball 703 is inserted into the positioning teeth 6011 one by one when the wave plate 601 rotates. In this embodiment, the ball bearing 703 is elastically pressed against the upper part of the oscillating disk 601 by the elastic part 7021 of the spring piece 702, so that when the oscillating disk 601 rotates, the ball bearing 703 can sequentially engage with the positioning teeth 6011. With the above arrangement, on the one hand, the rotating shaft 20 has a positioning feel when driving the oscillating disk 601 to rotate, and by opening the positioning teeth 6011 at a preset position on the surface of the oscillating disk 601, the user can stably and effectively rotate the rotating shaft to that position, thereby outputting a specific coded signal to the outside, which is convenient for the user to control the external device; on the other hand, when the rotating shaft 20 stops rotating, the engagement of the positioning teeth 6011 and the ball bearing 703 makes the rotating shaft 20 stably maintain its position, improving the stability of the device. Furthermore, in this embodiment, the bracket 701 includes a first connecting piece 7011 mounted above the undulating disk 601 and a second connecting piece 7012 mounted on the side of the first connecting piece 7011; the first connecting piece 7011 is provided with a first mounting hole for connecting with a spring piece 702, and the spring piece 702 is provided with a second mounting hole corresponding to the first mounting hole. During operation, a connecting post is connected in the first mounting hole and the second mounting hole so that the spring piece 702 is connected to the first spring piece 702; the second spring piece 702 is an elastic metal sheet, and a slot 7013 is provided in the second elastic sheet; the outer side of the base 101 is provided with a locking block 104 that matches the slot 7013. In the assembled state, the second connecting piece 7012 is elastically fastened to the outer side of the base 101, and at this time the locking block 104 is correspondingly locked in the slot 7013. Through the above settings, it can be directly and stably installed on the encoder body 50 in a way that is easy to disassemble.

[0042] The hollow encoder with a push-button switch function involved in this utility model, through the arrangement of switch body 10, rotating shaft 20, pressing plate 30 and switch signal output component, enables the switch encoder to have a switch indication function, and when pressed by using rotating shaft 20, the force is balanced, the structure is stable, suitable for industrial applications, and greatly improves the user experience.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
