The second limiting piece is arranged opposite to the first limiting piece. The first guide rail and the second guide rail are respectively arranged on the first limiting piece and the second limiting piece. The opposite ends of the connecting rod are respectively connected to the first guide rail and the second guide rail. When the rotating shaft rotates, the two ends of the connecting rod slide along the first guide rail and the second guide rail respectively.

[0022] The present application provides an encoding device. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 1 is a structural schematic diagram of an embodiment of the encoding device provided by the present application, Figure 2 is an exploded structural schematic diagram of an embodiment of the encoding device provided by the present application, Figure 3is a sectional structure schematic view of an embodiment of the encoding device provided by the present application along a view angle. The encoding device 100 can include an encoder 10, a first limiting member 20, a second limiting member 30, and a connecting rod 40. The encoder 10 is provided with a rotating shaft 11, when the rotating shaft 11 rotates under the operation of a user, the encoder 10 can acquire the rotating data of the rotating shaft 11. The first limiting member 20 is arranged on the encoder 10, the second limiting member 30 is connected to an end of the rotating shaft 11 away from the encoder 10, and the second limiting member 30 is arranged opposite to the first limiting member 20. The first limiting member 20 and the second limiting member 30 are respectively provided with a first guide rail 21 and a second guide rail 31, and opposite ends of the connecting rod 40 are respectively connected to the first guide rail 21 and the second guide rail 31. When the rotating shaft 11 rotates, the two ends of the connecting rod 40 respectively slide along the first guide rail 21 and the second guide rail 31, and when the rotating shaft 11 stops rotating, under the frictional force between the connecting rod 40 and the first limiting member 20 and the second limiting member 30, the two ends of the connecting rod 40 are respectively clamped in the first guide rail 21 and the second guide rail 31, so as to limit the rotation of the rotating shaft 11, thereby realizing the limiting of the rotating shaft 11.

[0023] The encoding device 100 provided by the present application, by respectively arranging the first limiting member 20 and the second limiting member 30 on the encoder 10 and the rotating shaft 11, respectively arranging the first guide rail 21 and the second guide rail 31 on the first limiting member 20 and the second limiting member 30, when the rotating shaft 11 stops rotating, the two ends of the connecting rod 40 can be respectively clamped in the first guide rail 21 and the second guide rail 31, thereby realizing the limiting of the rotating shaft 11, and since the first limiting member 20 and the second limiting member 30 have a smaller volume relative to the rack arranged on the outer periphery of the encoder 10, the volume of the encoding device 100 is reduced.

[0024] In order to reduce the motion interference between the connecting rod 40 and the first guide rail 21 and the second guide rail 31, the contact parts of the connecting rod 40 with the first guide rail 21 and the second guide rail 31, the first guide rail 21 and the second guide rail 31 can be polished, thereby reducing the friction between the connecting rod 40 and the first guide rail 21 and the second guide rail 31.

[0025] In an embodiment, the encoding device 100 can further include a mounting member 50, a cover plate 60, and a knob 70, as shown in Figure 4 、 Figure 5 、 Figure 6The mounting member 50 is connected to the encoder 10 for mounting the encoder 10, and the cover plate 60 and the mounting member 50 surround a receiving space 51, and the first limiting member 20 is mounted in the receiving space 51 so that the connecting portion is not exposed, and the appearance performance of the encoding device 100 is improved. The knob 70 is connected to the second limiting member 30, the outer periphery of the second limiting member 30 is provided with a scale line, and the cover plate 60 is correspondingly provided with a positioning line, and when the knob 70 is rotated to drive the rotating shaft 11 to rotate, the scale line cooperates with the positioning line to display the angle of rotation of the rotating shaft 11, thereby facilitating the user to obtain the angle data of rotation.

[0026] Specifically, the first limiting member 20 and the mounting member 50 can be plate-shaped. The first limiting member 20 and the mounting member 50 can be an integral structure or separately arranged. When the first limiting member 20 and the mounting member 50 are separately arranged, the first limiting member 20 can be directly connected to the encoder 10, or indirectly connected to the encoder 10 through the mounting member 50, that is, the mounting member 50 is first mounted to the encoder 10, the mounting member 50 is provided with a mounting hole 52 for accommodating the first limiting member 20, and then the first limiting member 20 is mounted in the mounting hole 52 through the rotating shaft 11.

[0027] The second limiting member 30 and the rotating knob 70 can be cylindrical, and the rotating knob 70 is sleeved on the second limiting member 30, which increases the force arm when the user rotates the rotating shaft 11, makes the rotation more labor-saving, and improves the user experience.

[0028] In an embodiment, the first guide rail 21 surrounds the outer periphery of the rotating shaft 11, the first guide rail 21 is arc-shaped, and the starting point of the second guide rail 31 is close to the rotating shaft 11 and extends away from the rotating shaft 11.

[0029] In an embodiment, the first guide rail 21 is spirally arranged around the outer periphery of the rotating shaft 11, and the second guide rail 31 is linear, as shown in Figure 7 、 Figure 8 , Figure 7 is a structure schematic view of the first limiting member according to an embodiment provided by the present application, Figure 8 is a structure schematic view of the second limiting member according to an embodiment provided by the present application. When the rotating shaft 11 rotates, the connecting rod 40 rotates, one end of the connecting rod 40 moves in a spiral annular motion along the first guide rail 21, so that the relative distance between one end of the connecting rod 40 and the rotating shaft 11 increases or decreases. Since the connecting rod 40 is an integral structure, the opposite end of the connecting rod 40 will move away from or close to the rotating shaft 11 under the drive of one end of the connecting rod 40. Since the two ends of the connecting rod 40 move along different tracks respectively, when the rotating shaft 11 stops rotating, the relative distance between the two ends of the connecting rod 40 and the rotating shaft 11 is different, and under the action of friction, the two ends of the connecting rod 40 are clamped in the first guide rail 21 and the second guide rail 31 respectively.

[0030] The stroke of the rotation shaft 11 of the encoding device 100 can be different in different use scenarios, and the rotation angle range of the rotation shaft 11 can be less than 360 degrees, greater than 360 degrees, or other rotation angles. Since different use requirements have different track length requirements for the first guide rail 21, the first limiting piece 20 is detachably mounted on the encoder 10 in a clamping, welding, threaded connection or other manner according to the stroke requirement of the rotation shaft 11. The second limiting piece 30 is correspondingly arranged with the first limiting piece 20, and the second limiting piece 30 can also be replaced according to the stroke requirement of the rotation shaft 11.

[0031] In an embodiment, the first guide rail 21 is a first groove 211 opened on the first limiting piece 20, and the second guide rail 31 is a second groove 311 opened on the second limiting piece 30, as shown in Figure 9 、 Figure 10 , Figure 9 is a structural schematic diagram of an embodiment of the connecting rod provided by the present application, Figure 10 is a structural schematic diagram of another embodiment of the connecting rod provided by the present application. The connecting rod 40 includes a first end portion 41, a rod body 42 and a second end portion 43 connected in sequence, and the first end portion 41 and the second end portion 43 are clamped in the first groove 211 and the second groove 311, respectively.

[0032] The first groove 211 can only penetrate one surface of the first limiting piece 20 along the thickness direction, as shown in Figure 9 , at this time, the opposite surface of the first limiting piece 20 can constrain the movement of the connecting rod 40. The first groove 211 can also penetrate two opposite surfaces of the first limiting piece 20 along the thickness direction, as shown in Figure 10 , at this time, a clamping ring 411 can be arranged on the first end portion 41, and the first end portion 41 is clamped on the first groove 211 through the clamping ring 411.

[0033] In order to facilitate the clamping of the second end portion 43 in the second groove 311, in an embodiment, the cross-sectional area of the second end portion 43 in the transverse direction is greater than that of the rod body 42 in the transverse direction, the second end portion 43 can be in the shape of a cone or a spherical platform, the cross section of the rod body 42 can be circular, elliptical, polygonal or triangular, and of course can also be other shapes.

[0034] The present application provides a control device, as shown in Figure 11 , Figure 11 is a structural schematic diagram of an embodiment of the control device provided by the present application. The control device 200 includes the encoding device 100 and the control device 210 as described above, the encoding device 100 is used to obtain operation data of a user, and the control device 210 can be controlled according to the operation data obtained by the encoding device 100. The control device 200 can be a mobile terminal, a game device, etc.

[0036] 1. The first limiting member 20 and the second limiting member 30 are respectively arranged on the encoder 10 and the rotating shaft 11, the first guide rail 21 and the second guide rail 31 are respectively arranged on the first limiting member 20 and the second limiting member 30, and the two ends of the connecting rod 40 can be clamped in the first guide rail 21 and the second guide rail 31, so that the rotating shaft 11 is limited. Since the first limiting member 20 and the second limiting member 30 are smaller in size than the rack arranged on the outer periphery of the encoder 10, the size of the encoding device 100 is reduced.

[0037] 2. The first limiting member 20 and the second limiting member 30 are detachably mounted on the encoder 10, and the corresponding first limiting member 20 and the second limiting member 30 can be mounted according to the stroke requirement of the rotating shaft 11.
