Referring to fig. 1 to 3, fig. 1 is a schematic perspective view illustrating a retracted mobile terminal 100, fig. 2 is a schematic perspective view illustrating an extended mobile terminal 100, and fig. 3 is a schematic exploded view illustrating the mobile terminal. The mobile terminal 100 of the embodiment of the present application includes a first case 10, a second case 20, a scroll 30, a flexible display 40, and a guide member 50. The first and second cases 10 and 20 are stacked and slidably coupled. The spool 30 is rotatably disposed within the first casing 10. One end of the flexible display screen 40 is fixedly connected to the second casing 20, and the other end is wound on the reel 30. The guide assembly 50 is disposed between the first case 10 and the second case 20, the guide assembly 50 includes a guide rod 52 and a slider 51 slidably connected to the guide rod 52, the slider 51 is fixedly connected to one of the first case 10 and the second case 20, and the guide rod 52 is fixedly connected to one of the first case 10 and the second case 20. Wherein the reel 30 can release or wind the flexible display 40 to adjust the display area of the mobile terminal 100 when the second housing 20 slides with respect to the first housing 10.

In the mobile terminal 100 of the embodiment of the present application, the first housing 10 and the second housing 20 are stacked and slidably connected, one end of the flexible display screen 40 is connected to the second housing 20, the other end of the flexible display screen is wound on the reel 30 in the first housing 10, when the second housing 20 slides relative to the first housing 10, the reel 30 can release or wind the flexible display screen 40, so that the portion of the flexible display screen 40 wound on the reel 30 can be wound outside the first housing 10 or the portion of the flexible display screen 40 wound outside the first housing 10 is wound on the reel 30, thereby achieving the purpose of adjusting the display area of the mobile terminal 100. And the guide assembly 50 is provided to guide the sliding between the first and second housings 10 and 20 to ensure stable sliding between the first and second housings 10 and 20. In this manner, the sliding movement between the first and second housings 20 can be guided by the provision of the guide assembly 50. While the reel 30 is provided to wind and release the flexible display 40 to adjust the display area of the mobile terminal 100 when the first and second cases 10 and 20 slide relatively. When needs portable, thereby can slide second shell 20 to the position that overlaps with first shell 10 so that spool 30 rolling flexible display screen 40, at this moment, display area is less, and mobile terminal 100's whole volume is less, and when the great display area of user's needs, thereby the accessible slides second shell 20 and makes spool 30 release flexible display screen 40 in order to enlarge display area in order to satisfy user's user demand, improves user experience and feels.

It is understood that the mobile terminal 100 in the embodiments of the present application includes, but is not limited to, an electronic device such as a mobile phone, a tablet, a computer, or other portable electronic devices. In the present embodiment, the mobile terminal 100 is described as an example of a mobile phone.

Specifically, the first casing 10 may be a main body of the mobile terminal 100, an accommodating space is formed inside the first casing 10, and a plurality of functional elements of the mobile terminal 100, such as a battery, a motherboard, a camera, a speaker, and the like, may be mounted in the first casing 10. The first shell 10 may be made of a hard material such as metal or glass, so as to protect the functional elements therein. The appearance shape of the first shell 10 can be approximately rectangular, and the peripheral corners of the outside of the first shell can be subjected to smooth transition treatment, so that the use requirement of a user can be met, and better hand feeling experience can be achieved.

As shown in fig. 4 and 5, the second case 20 may be disposed above the first case 10, with the second case 20 disposed to overlap the first case 10. The second housing 20 can slide relative to the first housing 10 in a direction away from the first housing 10, and at this time, a part of the second housing 20 and the first housing 10 can still be in an overlapped state, and another part of the second housing extends out of the first housing 10 and is not overlapped with the first housing 10. The second housing 20 may also be substantially rectangular in shape, thereby facilitating sliding between the second housing 20 and the first housing 10. The second casing 20 can be used to support the portion of the flexible display screen 40 fixedly connected to the second casing 20, so that the user can not generate concave deformation when touching and pressing the flexible display screen 40, and the flexible display screen 40 is protected. The thickness of the second shell 20 may be relatively smaller than that of the first shell 10, so that the overall thickness of the mobile terminal 100 can be reduced, and the user experience can be enhanced.

As shown in fig. 3 and 5, the reel 30 may have a cylindrical structure to facilitate rolling and releasing of the flexible display 40. The reel 30 may be disposed at an end of the first case 10, and particularly, may be disposed at an end of the first case 10 away from the second case 20. The diameter of the roll shaft 30 is smaller than the thickness of the first housing 10, and thus does not affect the winding and unwinding of the flexible display screen 40.

It should be noted that in the description of the present application, it is to be understood that the terms "central", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner" and "outer" indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present application.

The flexible display 40 may be a plastic substrate instead of a common glass substrate, but in some other embodiments, the flexible display 40 may also be a substrate made of glass or other materials. The flexible display screen 40 can be better bent and not easily broken by sticking a protective film on the back surface of the plastic substrate by using a film packaging technology.

The flexible display 40 may comprise a first portion 41 and a second portion 42. The first portion 41 may be disposed on a side of the second casing 20 opposite to the first casing 10, that is, above the second casing 20, the second portion 42 may be wound on the winding shaft 30, and the first portion 41 and the second portion 42 are connected without any mark or the first portion 41 and the second portion 42 are an integral structure. One end of the first portion 41 may be coupled to a side of the second case 20 away from the sliding direction of the first case 10, and the second portion 42 may be wound on the reel 30.

As shown in fig. 1, when the second housing 20 and the first housing 10 are completely overlapped, the first portion 41 is located above the second housing 20, and the second portion 42 is wound on the reel 30, and at this time, only the first portion 41 is exposed and used for display, the display area is small, and the second housing 20 and the first housing 10 are completely overlapped for carrying. As shown in fig. 2, when the second shell 20 slides relative to the first shell 10 in a direction away from the first shell 10, the first portion 41 slides along with the second shell 20, and simultaneously drives the second portion 42 to move, so that the reel 30 gradually releases the second portion 42, and the second portion 42 gradually extends out of the first shell 10 to increase the display area, thereby meeting the user's requirement for a larger display area.

It should be noted that, when the second shell 20 slides away from the first shell 10 relative to the first shell 10, the second portion 42 extends out of the first shell 10 under the driving of the second shell 20, and the second portion 42 does not abut against the second shell 20 and forms a certain interval with the first shell 10, so that the flexible display screen 40 may be damaged when touched. Therefore, one side of the flexible display screen 40 facing the second shell 20 can be provided with a supporting steel sheet, and the supporting steel sheet can increase the rigidity of the flexible display screen 40, so that when the second shell 20 slides in a direction away from the first shell 10, the touch and press second portion 42 can not deform to damage the flexible display screen 40 or influence the display effect of the flexible display screen 40.

As shown in fig. 4 to 8, the guide assembly 50 is mainly used to guide the sliding of the second housing 20 relative to the first housing 10 and to limit the sliding direction, so that the second housing 20 can only slide in a direction away from the first housing 10 or in a direction close to the first housing 10. The guide rod 52 may be a vertical rod-shaped structure, and specifically, may be a cylindrical rod-shaped structure or a square rod-shaped structure. The slider 51 may be a slider formed with a slide groove that engages with the guide bar 52. The number of the guide rods 52 may be one or more, a plurality of guide rods 52 may be arranged in parallel with each other, and the number of the sliders 51 may be arranged corresponding to the number of the guide rods 52. For example, the guide rod 52 may be provided as one, and the slider 51 may also be provided as one, so that the guide rod 52 and the slider 51 may be respectively installed at corresponding intermediate positions of the first casing 10 and the second casing 20; the number of the guide rods 52 may be two, and correspondingly, the number of the sliding members 51 may also be two, the two guide rods 52 are respectively disposed on two sides of the first housing 10 in parallel, and the two sliding members 51 are respectively disposed on corresponding positions on the second housing 20. The cross-sectional shape of the guide rod 52, the shape of the slider 51, and the number of guide rods 52 and sliders 51 are not limited by the present application.

The guide bar 52 may be fixedly coupled to the first case 10, and correspondingly, the slider 51 may be fixedly coupled to the second case 20. The sliding member 51 and the guide rod 52 may be slidably connected, the sliding member 51 may be sleeved on the guide rod 52, and the sliding member 51 may only slide on the guide rod 52, that is, the second housing 20 may only slide along the guide rod 52 relative to the first housing 10. Of course, the slider 51 may be fixedly coupled to the first housing 10, and the guide bar 52 may be fixedly coupled to the second housing 20. The present application does not limit this, and the two cooperate with each other to guide the sliding direction of the second housing 20 relative to the first housing 10.

Referring to fig. 4-8, in some embodiments, the first housing 10 is formed with a sliding groove 111, the guide rod 52 is disposed in the sliding groove 111 and fixedly connected to the first housing 10, the sliding member 51 is sleeved on the guide rod 52 and fixedly connected to the second housing 20, and the sliding member 51 can slide in the sliding groove 111 along the guide rod 52.

As such, the guide bar 52 and the slider 51 are disposed between the first case 10 and the second case 20, and the guide bar 52 and the slider 51 can relatively slide in the sliding groove 111 without affecting the overall thickness of the mobile terminal 100.

Specifically, the sliding groove 111 may be a vertical groove-type structure, and the guide bar 52 may be completely accommodated inside the sliding groove 111. The shape of the sliding groove 111 can match the shape of the sliding member 51, and the sliding member 51 is sleeved on the guide rod 52 and is accommodated in the sliding groove 111, so that the sliding member 51 can slide in the sliding groove 111 along the direction of the guide rod 52. The number of the sliding grooves 111 may correspond to the number of the guide rods 52 and the sliders 51, and the plurality of sliding grooves 111 may be arranged in parallel with each other.

Since the guide bar 52 and the slider 51 are disposed between the first case 10 and the second case 20, a mounting space for the guide bar 52 and the slider 51 is reserved between the first case 10 and the second case 20, and thus the overall thickness of the mobile terminal 100 is increased. The arrangement of the sliding groove 111 enables the guide rod 52 and the sliding part 51 to be accommodated in the first shell 10, and further installation of the guide rod 52 and the sliding part 51 can be achieved between the first shell 10 and the second shell 20 without reserving installation space of the guide rod 52 and the sliding part 51, and the second shell 20 can slide relative to the first shell 10 in a fitting manner, so that the overall thickness of the mobile terminal 100 is reduced, and the use experience of a user is improved.

Referring to fig. 3-7, in some embodiments, the guiding assembly 50 further includes a mounting seat 521, the mounting seat 521 is fixedly mounted in the sliding slot 111 by a fastening member (e.g., a screw, etc.), the mounting seats 521 are disposed at two ends of the sliding slot 111, and two ends of the guide rod 52 are respectively sleeved in the two mounting seats 521.

As such, the mounting seat 521 enables the guide bar 52 to be more stably mounted in the sliding groove 111 and to be detached from the first housing 10 by a fastener, facilitating maintenance of the mobile terminal 100.

Specifically, the mounting seats 521 may be disposed at both ends of the sliding groove 111, and mounting holes to be fitted with the guide rods 52 may be formed on the mounting seats 521, through which the guide rods 52 may be fixed. After the mounting seat 521 is fixed in the sliding groove 111, the upper surface of the mounting seat 521 does not protrude out of the sliding groove 111, and further the mutual sliding between the first shell 10 and the second shell 20 is not affected. The mounting base 521 can be connected by a fastener, for example, a screw hole can be provided on the mounting base 521, and the fixing connection is performed by a screw.

Referring to fig. 3, 5 and 8, in some embodiments, the sliding member 51 is provided with a resilient arm 511, the inner wall of the sliding groove 111 is formed with a locking groove 112, and the resilient arm 511 can cooperate with the locking groove 112 to lock the first shell 10 and the second shell 20 when the second shell 20 slides to a predetermined position relative to the first shell 10.

In this way, the mutual cooperation between the elastic arm 511 and the card slot 112 can lock the sliding member 51 at the preset position, that is, can lock the second shell 20 at the preset position when the second shell 20 slides relative to the first shell 10.

Specifically, the elastic arm 511 may be an elastic member having an elastic force, and the elastic arm 511 may be deformed under a certain pressure and may restore a shape after the pressure is removed, for example, a spring plate, a spring column, or the like. The elastic arm 511 may have an elastic protrusion 5111 formed thereon, and the shape of the elastic protrusion 5111 may match the shape of the slot 112. The elastic arms 511 may be provided at both sides of the slider 51, and the catching groove 112 may be provided at both sides of the inner wall of the sliding groove 111.

When the sliding member 51 slides in the sliding groove 111 under an external force, the elastic projection 5111 abuts against the inner wall of the sliding groove 111, and the inner wall of the sliding groove 111 applies a pressure to the elastic projection 5111 to deform the elastic arm 511 under the compression of the inner wall.

When the elastic projection 5111 is driven by the slider 51 to slide to the slot 112, the inner wall of the sliding slot 111 releases the pressure to the elastic arm 511 to restore the shape thereof, so that the elastic projection 5111 is engaged with the slot 112, and the slider 51 is locked at the position, i.e. the second housing 20 is locked at the position relative to the first housing 10.

When the locking of the second shell 20 relative to the first shell 10 needs to be released, a pushing force needs to be applied along the sliding direction of the second shell 20, so that the second shell 20 drives the sliding member 51 to slide, the sliding protrusion deforms under the action of the pushing force, and moves out from the clamping groove 112 to abut against the inner wall of the sliding groove 111, and the locking between the first shell 10 and the second shell 20 can be released.

The "preset position" may be a position where the second housing 20 is completely overlapped with respect to the first housing 10, or may be a position where the second housing 20 is away from the first housing 10 to fully unfold the flexible display 40. Of course, any position between the two positions may be adopted, and the preset position is not limited in the present application.

Referring to fig. 6, in some embodiments, the number of the card slots 112 is multiple, and the multiple card slots 112 are formed on the inner wall of the sliding slot 111 at intervals along the sliding direction of the second housing 20.

In this way, the second housing 20 can be locked at a plurality of positions, and then the display area of the flexible display screen 40 can be controlled, so that the user can apply different display areas under different situations, and better use experience is achieved.

Specifically, the card slot 112 is mainly used to cooperate with the elastic arm 511 to lock the second housing 20, so that the second housing 20 does not slide freely. The number of card slots 112 may be two, three, four, etc. Wherein the number of the card slots 112 is at least two so that the second housing 20 maintains a minimum volume when overlapped with respect to the first housing 10 or maintains a maximum display area when the second housing 20 is fully unfolded with respect to the first housing 10. The number of the card slots 112 should not be too large, and the use experience of the user during sliding can be influenced by too many card slots 112. The number of the card slots 112 is not limited in the present application, and may be selected according to various practical situations, such as the sliding distance of the second housing 20, the display scale of the image, and the like.

It is understood that when the second housing 20 is overlapped with respect to the first housing 10 and the second portion 42 of the flexible display 40 is wound on the reel 30, the card slot 112 may be opened at a position corresponding to the elastic projection 5111 of the elastic arm 511, and thus the second housing 20 may be locked at the position with respect to the first housing 10 to maintain a minimum volume of the mobile terminal 100.

When the second housing 20 slides relative to the first housing 10 to a maximum distance away from the first housing 10 and the second portion 42 of the flexible display 40 is completely unfolded outside the first housing 10, the slot 112 may also be opened at a position corresponding to the elastic protrusion 5111 on the elastic arm 511, so that the second housing 20 may be locked relative to the first housing 10 at the position to maintain a maximum display area of the mobile terminal 100.

Referring to fig. 3-5, in some embodiments, the mobile terminal 100 further includes a restoring mechanism 60, the restoring mechanism 60 is connected to the reel 30, and the restoring mechanism 60 is configured to apply a restoring force to the reel 30 to maintain the flexible display 40 in a tendency of being wound on the reel 30.

In this way, the restoring mechanism 60 keeps the flexible display 40 in a tendency of being wound on the winding shaft 30, so that the flexible display 40 is always in a tensioned state and cannot be damaged due to wrinkles generated when the flexible display is wound or released.

Specifically, when the second housing 20 is completely overlapped with respect to the first housing 10, the second portion 42 of the flexible display 40 is wound on the reel 30, and the restoring mechanism 60 has a tendency to restore the force to the reel 30 so that the second portion 42 remains wound on the reel 30; when the second shell 20 slides relative to the first shell 10 in a direction away from the first shell 10, the restoring force of the restoring mechanism 60 needs to be overcome to drive the second portion 42 to gradually release from the reel 30, and then the restoring force of the reel 30 to the flexible display screen 40 can enable the flexible display screen 40 to keep a flat and tensioned state, so that no wrinkle occurs; when the second shell 20 slides relative to the first shell 10 in a direction approaching the first shell 10, the restoring force of the restoring mechanism 60 may bring the second portion 42 to be wound back onto the winding shaft 30.

Referring to fig. 3 to 5, in some embodiments, the restoring mechanism 60 includes a coil spring 61, one end of the coil spring 61 is connected to the spool 30, and the other end is connected to the first housing 10, and the coil spring 61 is used to apply a restoring force to the spool 30.

In this way, one end of the coil spring 61 is connected to the winding shaft 30, and the other end is connected to the first housing 10, so that the winding shaft 30 can rotate relative to the first housing 10 under the restoring force of the coil spring 61, so that the flexible display screen 40 maintains the tendency of being wound on the winding shaft 30.

Specifically, the coil spring 61 may deform under a certain external force and generate a restoring force to the original shape, and the coil spring 61 can continuously provide a larger restoring force in a smaller space, so that the flexible display screen 40 may keep a rolling trend. Of course, the coil spring 61 may be an elastic member such as a clockwork spring, and the application is not limited thereto. One end of the coil spring 61 is connected to the spool 30 and the other end is fixedly connected to the first case 10 so that the spool 30 can rotate with respect to the first case 10. Meanwhile, one end of the second portion 42 is connected to the spool 30, and the coil spring 61 may provide a restoring force to the spool 30 to rotate the spool 30, so that the second portion 42 may be wound on the spool 30 by the restoring force of the coil spring 61.

When the second housing 20 slides relative to the first housing 10 in a direction away from the first housing 10, the second housing 20 drives the first portion 41 to slide, and further drives the second portion 42 to extend out of the first housing 10 against the restoring force of the coil spring 61, and the restoring force of the coil spring 61 provides a rotational force to the winding shaft 30, so that the winding shaft 30 pulls the flexible display screen 40 to keep a flat state. Meanwhile, when the second housing 20 is slid to a locked state with respect to the first housing 10, the second housing 20 is not pulled back by the restoring force of the coil spring 61 under the cooperation of the elastic arms 511 and the catching grooves 112.

Referring to fig. 5, 9 and 10, in some embodiments, the first housing 10 includes a body 11, an end cap 12 and a mounting member 13, the second housing 20 is stacked on the body 11, the end cap 12 is fixedly mounted at one end of the body 11, the mounting member 13 is mounted on the end cap 12, the winding shaft 30 is disposed in the end cap 12 and rotatably connected to the mounting member 13, the coil spring 61 is disposed on the mounting member 13, one end of the coil spring 61 is connected to the mounting member 13, and the other end of the coil spring 61 is connected to the winding shaft 30.

Thus, the arrangement of the end cover 12 and the mounting piece 13 enables the reel 30 to be mounted and dismounted more conveniently, the reel 30 is convenient to maintain, and the end cover 12 can play a role in protection and decoration.

Specifically, the end cover 12 may be installed at an end where the reel 30 is located, the end cover 12 covers the reel 30 and reserves a certain space between the end cover 12 and the reel 30 for rolling up the flexible display screen 40, and the end cover 12 may be detachably installed on the body 11, so as to facilitate maintenance of the reel 30 when the reel fails.
