Similarly, the sliding arm of the second sliding block slides linearly relative to the rotating axis in the second sliding groove, so that the second sliding block slides linearly relative to the guide rail frame, and the second sliding rod still slides nonlinearly relative to the guide rail frame under the driving of the second connecting rod. In other words, when the rotating shaft rotates relative to the fixed frame, the first sliding rod and the second sliding rod both slide nonlinearly relative to the guide rail frame, so that nonlinear frictional damping force is generated between the first sliding rod and the guide rail frame, and between the second sliding rod and the guide rail frame.

The rotating shaft 20 is rotatably connected to the fixing frame 10. The rotating frame 300 is fixedly coupled to the rotating shaft 20. When the rotating frame 300 rotates relative to the fixing frame 10, the rotating shaft 20 is driven to rotate relative to the fixing frame 10. The fixed shaft 40 is fixedly connected to the fixed frame 10. The rotating shaft 20 is sleeved on the outer surface of the fixing shaft 40 to realize the rotating connection with the fixing frame 10. At this time, the rotating mechanism 230 is in the unfolded state. Namely, the rotating frame 30 and the fixed frame 10 are relatively spread. Wherein, the unfolding angle between the rotating frame 30 and the fixed frame 10 is 90 degrees.

The second connecting rod 82 is connected between the second sliding block 62 and the second sliding rod 72, so as to drive the second sliding rod 72 to slide relative to the guide rail frame 50 under the driving of the second sliding block 62.

Referring to fig. 6, fig. 6 is an assembly structure diagram of the fixing frame 10, the rotating shaft 20, the rotating frame 30 and the fixing shaft 40 in the rotating mechanism 230 shown in fig. 4.

The fixing frame 10 includes a fixing plate 11 and two supporting arms 12, and the two supporting arms 12 are both fixedly connected to the fixing plate 11. The fixing plate 11 and the two supporting arms 12 can be integrally formed, so as to save the manufacturing cost of the fixing frame 10 and improve the overall strength of the fixing frame 10. In this embodiment, the fixing plate 11 is L-shaped. The fixing plate 11 includes a first portion 111 and a second portion 112, and the second portion 112 is fixedly coupled to one side of the first portion 111.

In other embodiments, the fixing plate 11 may have a "one" shape or other shapes, and the shape of the fixing plate 11 is not particularly limited in this application.

The two support arms 12 are respectively fixedly connected to two opposite sides of the second portion 112 and are arranged at intervals along the X-axis direction. Each support arm 12 is provided with a pivot hole (not shown) which penetrates the support arm 12 in the thickness direction of the support arm 12. Illustratively, the spindle bore is a circular bore. In this embodiment, the two support arms 12 are a first support arm 12a and a second support arm 12b, respectively, and the second support arm 12b is located on one side of the first support arm 12a facing the positive direction of the X-axis. Specifically, the first support arm 12a and the second support arm 12b are disposed opposite to each other. Wherein, the rotating shaft hole of the first supporting arm 12a and the rotating shaft hole of the second supporting arm 12b are oppositely arranged.

It should be understood that the relative arrangement mentioned in the description of the embodiments of the present application for the mobile terminal means at least a partially opposite arrangement. For example, the relative arrangement of the first support arm 12a and the second support arm 12b means that the orthographic projection of the first support arm 12a on the second support arm 12b overlaps the second support arm 12b, or the orthographic projection of the first support arm 12a on the second support arm 12b overlaps the second support arm 12 b. The relative arrangement mentioned later in the embodiments of the present application can be understood the same.

The rotating shaft 20 is provided with a rotating shaft hole (not shown) and a sliding groove 201. The rotation shaft hole is provided inside the rotation shaft 20. The opening of the rotating shaft hole is located on the right side surface of the rotating shaft 20. The rotation shaft hole is recessed in the direction of the right side surface to the left side surface of the rotation shaft 20, and penetrates the left side surface of the rotation shaft 20. That is, the rotary shaft hole penetrates the rotary shaft 20 in the axial direction of the rotary shaft 20. Wherein, the rotating shaft hole is cylindrical.

The opening of the sliding groove 201 is located on the outer surface of the rotating shaft 20. The sliding groove 201 is recessed from the outer surface toward the inner surface of the rotating shaft 20. Wherein, the sliding groove 201 is a spiral groove. I.e. the extension direction of the chute 201 is spiral. Illustratively, the sliding chute 201 takes a central axis of the rotating shaft 20 as a spiral axis, and a rotation angle of the sliding chute 201 around the spiral axis is equal to or greater than 180 degrees. In this embodiment, there are two sliding grooves 201, and the two sliding grooves 201 are a first sliding groove 201a and a second sliding groove 201 b. Specifically, the first sliding chute 201a and the second sliding chute 201b are arranged at intervals along the X-axis direction. In the clockwise direction (shown in the ω direction), the distance between the first chute 201a and the second chute 201b becomes smaller. It should be understood that the shape of the rotating shaft 20 is not limited to the illustrated cylindrical shape, and may be a square cylinder shape or other irregular cylindrical shape, and the shape of the rotating shaft 20 is not particularly limited in the present application.

The rotating shaft 20 is rotatably mounted to the stationary frame 10. That is, the rotating shaft 20 is mounted to the stationary frame 10 and is rotatable with respect to the stationary frame 10. In particular, the rotation axis 20 is located between the two support arms 12. The rotary shaft hole of the rotary shaft 20 and the rotary shaft holes of the two support arms 12 are disposed opposite to each other. Wherein, the first sliding slot 201a and the second sliding slot 201b are both towards the first portion 111 of the fixing frame 10. The first slide groove 201a is closer to the first support arm 12a than the second slide groove 201b, and the second slide groove 201b is closer to the second support arm 12b than the first slide groove 201 a. Further, the left side surface of the pivot shaft 20 may abut against the right side surface of the first support arm 12a, and the right side surface of the pivot shaft 20 may abut against the left side surface of the second support arm 12b, so as to increase damping when the pivot shaft 20 rotates with respect to the stationary frame 10, thereby facilitating fixation of the pivot shaft 20 at any angle when rotating with respect to the stationary frame 10.

The fixed shaft 40 is fixedly connected to the two support arms 12. Illustratively, the fixed shaft 40 may be extended into the rotation shaft hole of the first support arm 12a through the rotation shaft hole of the second support arm 12b and the rotation shaft hole of the rotation shaft 20 in order. Specifically, the partial fixing shaft 40 is located in the rotation shaft hole of the first support arm 12a, the partial fixing shaft 40 is located in the rotation shaft hole of the rotation shaft 20, the partial fixing shaft 40 is located in the rotation shaft hole of the second support arm 12b, and the partial fixing shaft 40 is extended with respect to the second support arm 12 b. The fixed shaft 40 is fixedly connected with the hole walls of the rotating shaft holes of the two support arms 12, so that the fixed shaft 40 is fixedly connected with the two support arms 12, and further the fixed shaft 40 is fixedly connected with the fixed frame 10. In other embodiments, the fixed shaft 40 is in interference fit with the rotation shaft holes of the two support arms 12 to realize the fixed connection between the fixed shaft 40 and the two support arms 12.

Referring to fig. 4 and 5, the rotating mechanism 230 further includes a fixing element 41, and the fixing element 41 is sleeved on the portion of the fixing shaft 40 extending relative to the second supporting arm 12b, so as to prevent the fixing shaft 40 from dropping from the rotating shaft holes of the two supporting arms 12 along the axial direction, and improve the connection stability between the fixing shaft 40 and the fixing frame 10.

The rotating shaft 20 is sleeved on the outer surface of the fixing shaft 40 and can rotate relative to the fixing shaft 40 to achieve the rotating connection with the fixing frame 10. In this embodiment, the inner diameter of the rotating shaft hole of the rotating shaft 20 is larger than the outer diameter of the fixed shaft 40. The rotating shaft mechanism 230 further includes a first damping member (not shown) disposed on the outer surface of the fixed shaft 40. Specifically, the first damping member is coupled between the stationary shaft 40 and the rotating shaft 20 to increase damping when the rotating shaft 20 rotates relative to the stationary shaft 40, thereby facilitating fixation of the rotating shaft 20 at any angle when rotating relative to the stationary shaft 40.

In other embodiments, the inner diameter of the rotating shaft hole of the rotating shaft 20 may be equal to or smaller than the outer diameter of the stationary shaft 40, or the rotating mechanism 230 may not include the first damping member, and the interference fit between the rotating shaft hole of the rotating shaft 20 and the stationary shaft 40 may also increase the damping when the rotating shaft 20 rotates relative to the stationary shaft 40.

The rotating frame 30 is fixedly coupled to an outer surface of the rotating shaft 20. The rotating frame 30 can rotate relative to the fixing frame 10 under the driving of the rotating shaft 20, so as to switch between a state of being folded relative to the fixing frame 10 and a state of being unfolded relative to the fixing frame 10. The slide groove 201 of the rotary shaft 20 is exposed to the rotary frame 30. It should be understood that the shape of the rotating frame 30 is not limited to the square plate shown in the figure, and may also be a circular plate or other shaped plate, and the shape and structure of the rotating frame 30 are not limited in particular in this application.

The fixed shaft 40 is fixedly connected to the fixed frame 10. The rotating shaft 20 is sleeved on the outer surface of the fixing shaft 40 to realize the rotating connection with the fixing frame 10. At this time, the rotating mechanism 230 is in the deployed state. Namely, the turret 30 and the fixed frame 10 are relatively spread. Wherein, the unfolding angle between the rotating frame 30 and the fixing frame 10 is 90 degrees.
