[0025] The encoder body 10 has an inner shaft 101 disposed above the middle portion thereof, and a mounting cavity 102 for mounting a display element is disposed within the inner shaft 101;

[0026] The undulation disk 20 is mounted on the encoder body 10, and a first step 201 is provided on a side of the undulation disk 20 close to the inner shaft 101, so that when the undulation disk 20 is mounted on the encoder body 10, a first accommodating cavity A is formed between the undulation disk 20 and the encoder body 10;

[0027] The outer shaft 30 is mounted on the outside of the inner shaft 101 and is connected to the main body of the undulating disk 20 so that when it rotates, it drives the undulating disk 20 to rotate relative to the encoder body 10. The bottom of the outer shaft 30 is mounted in the first accommodating cavity A and can move in the first accommodating cavity A when the outer shaft 30 is pressed;

[0028] The pressing plate 40 is mounted below the encoder body 10 and is provided with a first pressing portion 401 extending into the first accommodating cavity A. A second pressing portion 402 is provided below the pressing plate 40 so that when the outer shaft 30 moves vertically in the first mounting cavity 102, it abuts against the first pressing portion 401 and drives the pressing plate 40 to move through the first pressing portion 401.

[0029] The switch body 50 is installed below the pressing plate 40 and is used to abut against the second pressing portion 402 when the second pressing portion 402 moves downward, and transmit a signal to the external control device, and to drive the second pressing portion 402 to reset after the external force of the outer shaft 30 is removed.

[0030] Specifically, in this embodiment, the working status of the external device can be effectively judged according to the display of the display element located in the installation cavity 102; when working, the fluctuation disk 20 is driven to rotate by the outer shaft 30, so that the fluctuation disk 20 body and the encoder body 10 rotate relative to each other, so that the encoder body 10 can output a coded signal to the external control device according to the preset programming according to the size of the rotation amount, thereby effectively adjusting the set value of the external device connected to the hollow shaft encoder, which can be a volume size, pressure size, etc. that can be controlled according to the rotation amount. In addition, the user can switch the currently controlled set value type through the display screen based on the display of the display element, such as switching the volume adjustment to the pressure adjustment, and then adjust the set value of the currently selected type by rotating the outer shaft 30, so that the device is suitable for multiple different types of set value adjustment at the same time; in addition, the outer shaft 30 is pressed, and the signal is transmitted to the switch body 50 through the first pressing part 401 and the second pressing part 402 of the pressing plate 40, thereby effectively controlling the opening and closing of the external device.

[0031] The utility model relates to a hollow shaft encoder, which can effectively integrate the display module, the adjustment module and the switch module into one through the encoder body 10, the undulating disk 20, the outer shaft 30, the pressing plate 40 and the switch body 50, simplifies the device structure, has a reasonable structural setting, and greatly improves the user experience.

[0032] In a specific embodiment, a second step 103 is provided above the encoder body 10, so that when the undulating disk 20 is installed on the encoder body 10, a second accommodating cavity B is formed between the undulating disk 20 and the encoder body 10; the hollow shaft encoder also includes an encoding plate 60 and a brush 70; the encoding plate 60 is installed on the encoder body 10; the brush 70 is installed in the second accommodating cavity B and is connected to the undulating disk 20, and is used to rotate with the undulating disk 20 when the undulating disk 20 rotates, and the bottom of the brush 70 is provided with an elastic pressing end 702 that abuts against the encoder body 10, so that when the brush 70 rotates, it drives the elastic pressing end 702 to rotate, thereby generating a coding signal with the encoding plate 60 on the encoder body 10 and outputting it through the terminal.

[0033] Specifically, the bottom of the undulating disk 20 is provided with a connecting post 202, and the brush 70 is provided with a connecting hole 701 corresponding to the connecting post 202. The brush 70 and the undulating disk 20 are connected through the connecting post 202 and the connecting hole 701. During operation, the undulating disk 20 drives the brush 70 to rotate. The elastic pressing end 702 at the bottom of the brush 70 presses against the encoder plate 60 while moving relative to the encoder plate 60, thereby generating a coded signal with the encoder plate 60 on the encoder body 10, which is output through the terminal.

[0034] In a specific embodiment, the hollow shaft encoder also includes a bracket 80 and a spring clip 90; the bracket 80 is installed on the fluctuation disk 20, and the fluctuation disk 20 is provided with a third step 203 to form a third accommodating cavity C between the fluctuation disk 20 and the bracket 80; the spring clip 90 is installed in the third accommodating cavity C and is connected to the bracket 80, and the spring clip 90 is provided with an elastic pressing protrusion 901 that presses against the upper part of the fluctuation disk 20.

[0035] Specifically, the undulating disk 20 is provided with a plurality of positioning teeth that cooperate with the elastic pressure protrusions 901. When the undulating disk 20 rotates, the plurality of positioning teeth cooperate with the elastic pressure protrusions in turn. On the one hand, this enables the outer shaft 30 to have a sense of positioning when driving the undulating disk 20 to rotate, so that the user can stably and effectively rotate the outer shaft 30 to this position, thereby outputting a specific coded signal to the outside, making it easier for the user to control the external device; on the other hand, when the outer shaft 30 stops rotating, the cooperation between the positioning teeth and the elastic pressure protrusions 901 enables the outer shaft 30 to maintain its position stably, thereby improving the stability of the device.

[0036] In a specific embodiment, a clamping block 301 is provided on the outer circumference of the outer shaft 30; a clamping groove 204 for installing the clamping block 301 is provided on the side of the undulating plate 20 close to the outer shaft 30, and in the assembled state, the clamping groove 204 is connected to the first accommodating cavity A.

[0037] Specifically, in this embodiment, the undulating disk 20 and the outer shaft 30 are connected by the clamping block 301 and the clamping slot 204, so that the outer shaft 30 drives the undulating disk 20 to rotate when it rotates. At the same time, since the clamping slot 204 is connected to the first accommodating chamber A in the assembled state, when the outer shaft 30 is pressed, the outer shaft 30 can move vertically in the first accommodating chamber A.

[0038] In a specific embodiment, the switch body 50 is provided with a pot piece 501 for pressing against the second pressing portion 402, and a signal contact 502 for transmitting a pressing signal is provided below the pot piece 501. Specifically, in this embodiment, when the second pressing portion 402 moves downward under the drive of the pressing plate 40 and presses the pot piece 501, the pot piece 501 then contacts the signal contact 502, causing the signal contact 502 to transmit a signal through the switch body 50, thereby enabling the external control device to control the device to open and close. After the external force of the outer shaft 30 is removed, the pot piece 501 resets, thereby driving the second pressing portion 402 to reset, thereby resetting the pressing plate 40, the first pressing portion 401, and the outer shaft 30.

[0039] The utility model relates to a hollow shaft encoder, which can effectively integrate the display module, the adjustment module and the switch module into one through the encoder body 10, the undulating disk 20, the outer shaft 30, the pressing plate 40 and the switch body 50, simplifies the device structure, has a reasonable structural setting, and greatly improves the user experience.

[0040] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention.
