Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a mobile terminal according to an embodiment of the present application, and fig. 2 is a detailed partial view of the mobile terminal provided in fig. 1, where the mobile terminal includes:

the mobile terminal comprises a mobile terminal body 1 and a sliding assembly 2;

a groove structure 3 is arranged at the edge of the side surface of the mobile terminal body 1, and the sliding assembly 2 is positioned in the groove structure 3;

and a chute 6 is arranged on the chute wall of the groove structure 3, and the sliding component 2 is in sliding connection with the mobile terminal body 1 through the chute 6.

In the embodiment of the present application, fig. 1 shows the groove structure 3 disposed at the right side edge of the mobile terminal body 1, and in practical applications, the groove structure may also be disposed at the left side edge, and may be located at the upper longitudinal portion, the lower longitudinal portion, or the middle longitudinal portion of the left side edge or the right side edge, which is not illustrated by way of example.

As can be seen from fig. 2, the sliding grooves 6 are located on the groove walls of the groove structure 3, and the sliding grooves 6 are disposed on both groove walls of the groove structure 3, so that the sliding assembly 2 can slide along the groove direction of the sliding grooves 6. When the sliding component 2 slides to the side of the bottom of the sliding slot 6 (the innermost side and the innermost side of the sliding slot), the sliding component 2 can be in close contact with the mobile terminal body 1, and in practical applications, when the sliding component 2 slides to the side of the bottom of the sliding slot 6 (the innermost side and the innermost side of the sliding slot), the sliding component 2 may also leave a small amount of clearance with the mobile terminal body 1, as shown in fig. 2, the small amount of clearance is left. When the gap is small enough, the mobile terminal body 1 and the sliding assembly 2 can be considered to be in close contact, and if the mobile terminal body is provided with the first display screen and the sliding assembly is provided with the second display screen, the first display screen and the second display screen can be spliced into a whole display screen for displaying content. If the first display screen and the second display screen are both designed without frames, the first display screen and the second display screen are combined together to achieve a better display effect.

Further, referring to fig. 2 or fig. 3, fig. 3 is a schematic structural view of the mobile terminal provided in fig. 2 when the sliding assembly is slid to the outermost side of the groove, and a sliding structure is provided in the sliding groove 6:

the sliding structure comprises a rotating shaft 5;

the end of the rotating shaft 5 penetrates into the inside of the sliding groove 6.

In the embodiment of the present application, the rotating shaft 5 may be fixed on the sliding assembly 2, and the rotating shaft 5 slides from left to right or from right to left (the orientation shown in fig. 2 or fig. 3) in the sliding slot 6, so as to realize the separation or attachment of the sliding assembly 2 and the mobile terminal body 1. The existence of the rotating shaft 5 can realize not only the sliding of the sliding component 2 relative to the mobile terminal body 1, but also the rotation of the sliding component 2 relative to the mobile terminal body 1, for example, the rotating shaft 5 on the sliding component 2 slides to the outermost side of the sliding slot 6 (the rightmost side of the sliding slot shown in fig. 3), and the sliding component 2 can realize the rotating operation relative to the mobile terminal body 1.

Further, referring to fig. 4, fig. 4 is a schematic structural diagram of the inside of the sliding slot of the mobile terminal shown in fig. 2 or fig. 3, wherein the sliding structure further includes:

a damping ring 9 located inside the chute 6, a first spring 7 located inside the chute 6, a second spring 8 located inside the chute 6;

the rotating shaft 5 extends into the damping ring 9, and two connecting positions oppositely arranged on the outer surface of the damping ring 9 are respectively connected with the first end of the first spring 7 and the first end of the second spring 8; the second end of the first spring 7 is connected to the innermost side (left side in the figure) of the chute; the second end of the second spring 8 is connected to the outermost side (right side in the figure) of the chute.

In the embodiment of the present application, if the hinge 5 is freely slidable in the sliding slot 6, the sliding assembly 2 is freely slidable relative to the mobile terminal body 1, which is inconvenient for the user to use, and can be achieved by the damping structure shown in the figure: a damping ring 9, two springs, control the spindle 5 to be fixed in one position, so that the sliding assembly 2 is fixed in place. The state of the first spring 7 and the second spring 8 may be set to control the sliding assembly 2 to be closely attached to the mobile terminal body 1, for example, when the sliding assembly 2 is closely attached to the mobile terminal body 1, the first spring 7 is in an extended state, and the second spring 8 is in a compressed state, in this state, because the stress of the springs may control the sliding assembly 2 to continue to move to one side of the mobile terminal body 1 and receive stress, the mobile terminal body 1 may be closely attached to the sliding assembly 2. When the user wants to pull the two apart, the sliding unit 2 is pulled to the side away from the mobile terminal body 1 (the right side in the figure).

Further, referring to fig. 5, fig. 5 illustrates an effect of the mobile terminal provided by the embodiment of the present application; the left side in fig. 5 is the front side of the mobile terminal, and the right side in fig. 5 is the back side of the mobile terminal.

The sliding assembly 2 comprises:

the second surface is arranged opposite to the first surface;

The first face of sliding assembly has set up the display module assembly, and corresponding will set up the display screen, the display screen can show information such as mobile terminal's electric quantity, time, date, also can with the content that treats the demonstration is shown jointly to the display screen that sets up on the mobile terminal body. The second side can be provided with some functional modules. Therefore, when the sliding assembly rotates the display module to the front side, the relevant information can be displayed, and when the sliding assembly rotates to the back side, the screen is turned off.

Further, referring to fig. 5, the mobile terminal body includes:

a first display screen;

In the embodiment of the present application, the first display screen is the display screen in fig. 5, and the second display screen is a small screen displaying the power, time, and date.

Further, the rotating shaft 5 is fixedly connected with the sliding component 2, and the central axis 10 of the rotating shaft 5 coincides with the central axis of the sliding component 2.

Of course, in practical applications, the second display screen may display information such as electric quantity, date, time, and the like when the mobile terminal is powered on or the first display screen is turned on.

And the second display screen is in a screen extinguishing state when the included angle between the first display screen and the second display screen is not within a preset range. When the second display screen is turned to the back of the mobile terminal body, the second display screen does not display any information and is in a screen off state.
