That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0039] Referring to the appended drawings of the specification of the present utility model Figures 1 to 15 In the following description, a knob device according to a preferred embodiment of the present utility model will be disclosed and described, wherein the knob device includes a base 10, a circuit board 20, an encoder 30, an operation knob 40, and a transmission part 50.

[0040] Specifically, the encoder 30 is mounted on the circuit board 20. Manual soldering is not required for the two, and the solder joints are small. The encoder 30 can be soldered synchronously with other electronic components (such as resistors and capacitors). The circuit board 20 is disposed at the bottom of the base 10. The operation knob 40 is rotatably disposed on the top of the base 10. The transmission part 50 connects the movable part of the encoder 30 and the operation knob 40. When the user rotates the operation knob 40, the operation knob 40 drives the movable part of the encoder 30 to rotate through the transmission part 50, so that the encoder 30 performs encoding to change the working state of the device configured with the knob device of the present invention.

[0041] More specifically, the transmission part 50 is a transmission gear, which has a driven tooth 51 on its outer side, and the transmission part 50 is configured to be rotatable relative to the base 10 about its own central axis. The operation knob 40 has a driving tooth 41. The driving tooth 41 of the operation knob 40 meshes with the driven tooth 51 of the transmission part 50, so that the transmission part 50 is drivably connected to the operation knob 40. That is to say, when the user rotates the operation knob 40 and the operation knob 40 drives the movable part of the encoder 30 to rotate through the transmission part 50, the transmission part 50 only rotates about its own central axis, and the relative position of the transmission part 50 and the base 10 remains unchanged.

[0042] Compared with the knobs of the prior art, in the knob device of the present invention, the transmission part 50 enables the middle part of the encoder 30 not to need to reserve a through groove for the pressing block to move. In this way, the encoder 30 can be miniaturized, the structure of the knob device can be simplified, and the cost of the knob device can be reduced. At the same time, when the knob device is pressed and operated, the encoder 30 is not stressed, so that the encoder 30 is not easily damaged, which is beneficial to ensuring the reliability of the knob device and prolonging the service life of the knob device.

[0043] Refer to the attached Figure 5, the base 10 includes a cylinder 11 and a base plate 12 integrally extending outward from the bottom of the cylinder 11, that is, the cylinder 11 and the base plate 12 are of an integral structure. For example, by injection molding, the plastic material can be allowed to integrally form the cylinder 11 and the base plate 12 of the base 10. The cylinder 11 has a receiving space 111 and a side opening 112 communicating with the receiving space 111. The operation knob 40 has a knob cavity 42, and the driving teeth 41 are formed on the inner wall of the operation knob 40. The operation knob 40 is rotatably sleeved on the outside of the cylinder 12 in such a way that the cylinder 11 extends into the knob cavity 42 of the operation knob 40, and the side opening 112 of the cylinder 11 corresponds to the driving teeth 41 of the operation knob 40. The central axis of the transmission part 50 itself is located in the receiving space 111 of the cylinder 11, and a part of the outside of the transmission part 50 extends to the outside of the cylinder 11 through the side opening 112 of the cylinder 11, so that the driven teeth 51 of the transmission part 50 and the driving teeth 41 of the operation knob 40 are engaged outside the cylinder 11. In this way, the knob device of the present invention can have a more compact structure, which is beneficial to the miniaturization of the knob device.

[0044] Reference attachment Figure 3 and Figure 5 , the base 10 includes a supporting tray 13, the supporting tray 13 is arranged at a position of the cylinder 11 adjacent to the side opening 112, and the supporting tray 13 is located in the receiving space 111 of the cylinder 11, and the bottom side of the transmission part 50 is rotatably installed on the supporting tray 13.

[0045] Preferably, the base 10 includes a cover 14, the cover 14 is installed on the supporting tray 13, and the top side of the transmission part 50 is rotatably installed on the cover 14. That is to say, the opposite sides of the transmission part 50 are respectively rotatably installed on the supporting tray 13 and the cover 14, and since the cover 14 is installed on the supporting tray 13, during the process that the user rotates the operation knob 40 and the operation knob 40 drives the movable part of the encoder 30 to rotate through the transmission part 50, the transmission part 50 will not shake, so as to avoid the lateral force on the movable part of the encoder 30, thereby ensuring the reliability of the coding device.

[0046] It is worth mentioning that the installation method of the cover 14 and the supporting tray 13 is not limited in the knob device of the present invention. For example, the cover 14 can be installed on the supporting tray 13 by a buckle. Specifically, reference attachment Figure 13 and Figure 14, the cover body 14 has a buckle 141 which can latch the side of the bearing tray 13, so that the cover body 14 is reliably mounted on the bearing tray 13.

[0047] Further, referring to the attached Figure 5 , the bearing tray 13 has a tray perforation 131, and the rotating shaft 52 of the transmission part 50 extends through the tray perforation 131 of the bearing tray 13 to the mounting hole 31 of the movable part of the encoder 30. In this way, the movable part of the encoder 30 is mounted on the rotating shaft 52 of the transmission part 50, so that the movable part of the encoder 30 is drivably connected to the transmission part 50. Optionally, in other examples of the knob device of the utility model, the movable part of the encoder 30 extends through the tray perforation 131 of the bearing tray 13 to the transmission part 50, and the movable part of the encoder 30 is mounted on the transmission part 50, so that the movable part of the encoder 30 is drivably connected to the transmission part 50.

[0048] Referring to the attached Figures 1 to 5 , Figure 7 and Figure 8 , the knob device further includes a push switch 60 and a pressing part 70. The push switch 60 is mounted on the circuit board 20. The knob cavity 42 of the operating knob 40 is a cavity with an open top. The pressing part 70 has an extension column 71. The pressing part 70 is pressably arranged in the knob cavity 42 of the operating knob 40, and the extension column 71 of the pressing part 70 is suspended above the push switch 60. When the pressing part 70 is pressed, the extension column 71 of the pressing part 70 presses down the push switch 60 to operate the push switch 60.

[0049] Continuing to refer to the attached Figure 5 , Figure 7 and Figure 8 , the knob device further includes a compression spring element 100. The compression spring element 100 is configured such that the bottom of the compression spring element 100 remains stationary relative to the base 10 and the top of the compression spring element 100 abuts against the pressing part 70. When the pressing part 70 is pressed, on the one hand, the extension column 71 of the pressing part 70 presses down the push switch 60 to operate the push switch 60. On the other hand, the pressing part 70 compresses the compression spring element 100 downward, causing the compression spring element 100 to deform and store elastic potential energy. Thus, after the external force pressing the pressing part 70 is withdrawn, the compression spring element 100 pushes the pressing part 70 upward to reset it during the process of restoring to the initial state.

[0050] Referring to the attachedFigure 3 , Figure 5 , Figure 7 and Figure 8 , the base 10 includes a suspension portion 15, the suspension portion 15 is disposed on the cylinder 11, and the suspension portion 15 is located in the accommodation space 111 of the cylinder 11. The suspension portion 15 has a suspension through hole 151, and the position of the suspension through hole 151 corresponds to the position of the push switch 60. Wherein, the extension column 71 of the pressing portion 70 is suspended above the push switch 60 after passing through the suspension through hole 151 of the suspension portion 15. At the same time, the suspension through hole 151 of the suspension portion 15 and the extension column 71 of the pressing portion 70 cooperate with each other to limit the moving direction of the pressing portion 70, so that the moving direction of the pressing portion 70 is limited to the height direction only. Preferably, the suspension portion 15 and the cylinder 11 are of an integral structure. The bottom of the compression spring element 100 can abut against the suspension portion 15, so that the position of the bottom of the compression spring element 100 relative to the base 10 can remain stationary.

[0051] In addition, a ring body 152 can extend upward from the middle of the suspension portion 15, and the ring body 152 surrounds the extension column 71 of the pressing portion 70. In this way, the suspension portion 15 can provide a better effect of restricting the moving direction of the pressing portion 70. The compression spring element 100 can be sleeved on the ring body 152 of the suspension portion 15. In this way, the compression spring element 100 can be stably held between the pressing portion 70 and the suspension portion 15 to improve the reliability and stability of the knob device.

[0052] In addition, the bearing tray 13 and the suspension portion 15 can be integrally formed, so that the bearing tray 13 is disposed at a position adjacent to the side opening 112 of the cylinder 11 by the suspension portion 15.

[0053] Refer to Appendix Figure 5 , Figure 7 and Figure 8 , the knob device includes a display portion 80, the display portion 80 is disposed on the pressing portion 70, and the display portion 80 is connected to the circuit board 20. Preferably, the pressing portion 70 has an embedding groove 72, the bottom of the display portion 80 is embedded in the embedding groove 72 of the pressing portion 70, and the bottom of the display portion 80 can be buckled by the pressing portion 70 so that the display portion 80 is disposed on the pressing portion 70.

[0054] Preferably, refer to Appendix Figure 5 , Figure 7 and Figure 8, the knob device includes a light-transmitting top cover 90 which is stacked on the display part 80 for protecting the display part 80.

[0055] Reference appendix Figure 4 and Figure 6 , the inner wall of the operation knob 40 has a circular groove 43. The knob device includes at least one elastic piece 110. At least one end of the elastic piece 110 is installed on the cylinder body 11, and the middle part of the elastic piece 110 protrudes into the groove 43 of the operation knob 40. When the user rotates the operation knob 40, the operation knob 40 can drive the middle part of the elastic piece 110 to deform, so that the middle part of the elastic piece 110 slides from one groove 43 of the operation knob 40 into another groove 43. In this way, on the one hand, the hand feeling of the user when rotating the operation knob 40 can be increased; on the other hand, when the user does not rotate the operation knob 40, the friction force generated between the operation knob 40 and the middle part of the elastic piece 100 prevents the operation knob 40 from rotating automatically.

[0056] Specifically, the cylinder body 11 has a notch 113 and an installation groove 114 communicating with the notch 113. The end of the elastic piece 110 is slidably installed in the installation groove 114 of the cylinder body 11. During the process of the user rotating the operation knob 40, the inner wall of the operation knob 40 determines that the middle part of the elastic piece 110 deforms towards the notch 113 of the cylinder body 11, and at the same time, the elastic piece 110 can move in the installation groove 114 of the cylinder body 11, so that the middle part of the elastic piece 110 can slide from one groove 43 of the operation knob 40 into another groove 43. Preferably, the elastic piece 110 can be a metal elastic piece.

[0057] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments.
