[0030] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments.
[0031] In an embodiment of the present application, as shown in Figures 1-4 A scroll wheel structure for mouse and keyboard is provided, which comprises a scroll key 10 and a control button 20. An encoder 30 is arranged in the scroll key 10. The encoder 30 is provided with a first connecting rod 31 and a second connecting rod 32 extending outward at both ends respectively. Two groups of control buttons 20 are arranged on both sides of the scroll key 10. The control button 20 is provided with a detachable fixed shell 21. The first connecting rod 31 is fixedly connected between the control button 20 and the fixed shell 21, and the second connecting rod 32 is fixedly connected between the control button 20 and the fixed shell 21. An adjusting unit 40 for stroke adjustment is arranged between the fixed shell 21 and the first connecting rod 31 and the second connecting rod 32.
[0032] By setting the adjusting unit 40, by adjusting the screw 41 of the adjusting unit 40 and the threaded hole 33 on the first connecting rod 31 and the second connecting rod 32, the connection height between the first connecting rod 31 and the second connecting rod 32 at both ends of the encoder 30 and the fixed shell 21 can be flexibly adjusted, that is, by simply adjusting the adjusting screw 41 to change the relative height of the connecting hole in the encoder 30, it is ensured that the roller 11 key can be smoothly exposed to the outside for user operation, and the universality and adaptability of the roller 11 structure are enhanced, without the need to replace the roller 11 key of corresponding size for different sizes of mouse or keyboard, thereby reducing the cost expenditure.
[0033] By setting two groups of control buttons 20, when the roller key 10 is pressed, the control buttons 20 at both ends are forced at the same time, so that the roller key 10 can be pressed balancedly, avoiding the inclination feeling when the previous single control button 20 is pressed, improving the user's use feeling, and the functions of the control buttons 20 at both ends can be customized to meet the individual needs of users.
[0034] Preferably, the adjusting unit 40 comprises an adjusting screw 41. The adjusting screw 41 is threadedly connected to the first connecting rod 31 and the second connecting rod 32. The first connecting rod 31 and the second connecting rod 32 are provided with threaded holes 33 corresponding to the adjusting screw 41, and the threaded holes 33 are arranged vertically. A rubber ring 42 is arranged between the adjusting screw 41 and the first connecting rod 31 and the second connecting rod 32. By setting the threadedly connected adjusting screw 41, the relative position between the first connecting rod 31, the second connecting rod 32 and the control button can be accurately adjusted, thereby realizing the fine adjustment of the height of the encoder 30, without the need to replace the roller 11 key of corresponding size for different sizes of mouse or keyboard, thereby reducing the cost expenditure.
[0035] Further, one end of the adjusting screw 41 is provided with a limiting boss. The other end of the adjusting screw 41 vertically penetrates the first connecting rod 31 and the second connecting rod 32, and abuts against the top end of the control button 20. By abutting the adjusting screw 41 against the control button 20, when the adjusting screw 41 is tightened downward, the other end of the adjusting screw 41 presses the contact part 22 of the roller screw downward, so that the first connecting rod 31 and the second connecting rod 32 drive the encoder 30 to move downward, thereby realizing the downward adjustment of the encoder 30. Conversely, loosening the adjusting screw 41 upward, that is, realizing the upward adjustment of the encoder 30.
[0036] Preferably, the top end of the control button 20 is provided with an upwardly protruding contact part 22. The contact part 22 is in a cross structure. The contact part 22 abuts against the bottom end of the first connecting rod 31 and the second connecting rod 32, respectively. By setting the contact part 22 in a cross structure, the contact part 22 and the first connecting rod 31 and the second connecting rod 32 are in point contact, so that the hand feeling when the roller key 10 is pressed is better, thereby improving the user's use experience.
[0037] Preferably, the control button 20 is provided with a clamping block 23 extending outward on both sides, and the clamping block 23 has a trapezoidal structure. The bottom end of the fixed shell 21 is provided with a clamping groove 211 corresponding to the clamping block 23. The clamping block 23 can enter or disengage the clamping groove 211. By setting the clamping block 23 and the clamping groove 211, and by matching the clamping block 23 with the clamping groove 211, the scroll key 10 and the fixed shell 21 can be quickly disassembled and assembled.
[0038] Preferably, in this embodiment, the encoder 30 is a mechanical encoder 30, such as a TTC gold core, a Kaili red core, etc. The encoder 30 includes a first fixed disc 34, a second fixed disc 35, and a central shaft 36. The first fixed disc 34 and the second fixed disc 35 are distributed on both sides of the scroll key 10. The central shaft 36 is arranged in the center of the scroll key 10, and one end of the central shaft 36 is fixedly connected to the inner side of the first fixed disc 34. The other end of the central shaft 36 is provided with two groups of symmetrically distributed clamping portions 361, and the other end of the central shaft 36 penetrates the center of the second fixed disc 35, and the clamping portions 361 are tightly connected with the outer side of the second fixed disc 35. The first connecting rod 31 is fixedly connected to the side of the central shaft 36 close to the first fixed disc 34, and the second connecting rod 32 is fixedly connected to the side of the central shaft 36 close to the second fixed disc 35. By setting the clamping portions 361, the first fixed disc 34 and the second fixed disc 35 are clamped to each other in the center of the scroll key 10 through the clamping portions 361, which simplifies the installation steps between the first fixed disc 34 and the second fixed disc 35.
[0039] Further, the first fixed disc 34 is provided with an elastic sheet 37. The inner side of the first fixed disc 34 is provided with a first fixed portion 341 for fixing the elastic sheet 37. A plurality of groups of convex points are arranged at equal intervals on the elastic sheet 37. By setting the convex points, when the scroll key 10 rotates, the convex points on the elastic sheet 37 rotate relative to the limiting portions on the scroll key 10, that is, the convex points on the elastic sheet 37 contact the limiting portions at different positions of the scroll key 10, thereby generating a rotating feeling.
[0040] Still further, the inner side of the second fixed disc 35 is provided with a circuit sheet. The circuit sheet is provided with a terminal 38. The terminal 38 is arranged perpendicularly to the circuit sheet, and the terminal 38 is in close contact with the outer extension of the second fixed disc 35.

The fixed plate is provided with a plurality of limiting portions corresponding to the convex points on the side close to the first fixed disc 34. The scroll seat 12 is rotated, and the convex points are in contact with the limiting portions at different positions. The fixed plate is provided with a brush sheet 13 and a second fixing portion 121 for fixing the brush sheet 13 on the side close to the second fixed disc 35. By arranging the brush sheet 13 and the circuit sheet, when the scroll wheel 11 rotates, the scroll wheel 11 drives the brush sheet 13 on the scroll seat 12 to rotate synchronously, so that the brush sheet 13 rotates relative to the circuit sheet. An encoding signal is generated through the sliding contact between the circuit sheet and the brush. At the same time, when the scroll seat 12 rotates, the convex points on the elastic sheet 37 are in contact with the limiting portions at different positions on the scroll seat 12, thereby generating a rotating hand feeling.
[0042] Further, the scroll key is internally provided with a lamp tube 39 for emitting light. The lamp tube 39 is provided with a clearance groove between the scroll key. By arranging the lamp tube 39, when the scroll key 10 rotates, the lamp tube 39 is turned on with the rotation of the scroll key 10, thereby improving the appearance of the structure of the scroll wheel 11.
[0043] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is specifically described. These descriptions are only for explaining the principle of the present application, and cannot be explained as the limitation of the protection scope of the present application in any way. Based on the explanation herein, any modification, equivalent replacement and improvement within the spirit and principle of the present application, and other specific embodiments of the present application which can be thought by those skilled in the art without creative labor, should be included in the protection scope of the present application.
