The electronic device of the embodiment of the application can be an electronic device with a display screen, such as but not limited to a mobile phone, a tablet computer, a personal computer, a television and the like.

As shown in fig. 1 to 3, an electronic device according to some embodiments of the present application includes a first housing 1, a second housing 2, a reel 3, a display 4, and a stopper. The second housing 2 is disposed on the first housing 1 and can slide along the length direction of the first housing 1. The reel 3 is rotatably connected to the first housing 1. One end of the display screen 4 is connected to the reel 3 by a coil spring 6, and the other end is fixed to the second housing 2. The limiting member is disposed on the first casing 1, and the second casing 2 has a first position and a second position relative to the first casing 1. When the second housing 2 is located at the first position, the display screen 4 is deployed on the reel 3, and the limiting member limits the second housing 2 at the first position and can release the limitation on the second housing 2 under the external force. With the second housing 2 in the second position, the display screen 4 is at least partially wound around the reel 3.

The direction indicated by the arrow shown in fig. 1 is the sliding direction of the second housing 2 relative to the first housing 1, i.e. the length direction of the first housing 1. The reel 3 is provided at one end of the first casing 1 in the longitudinal direction. In the length direction of the first shell 1, the second shell 2 can slide between a first position and a second position, and the display screen 4 is unfolded and rolled. A part or all of the display screen 4 may be wound on the reel 3. The stopper releases the restriction on the position of the second housing 2 by an external force.

In some embodiments of the present application, the display screen 4 comprises a first section 401 and a second section 402 connected to each other, the first section 401 being windable or uncoilable from the reel 3, the second section 402 being kept uncoilable during the windable and uncoilable operation of the first section 401. The first section 401 is a flexible screen, and the second section 402 may be the same flexible screen as the first section 401, or may be a rigid screen. It should be noted that the display 4 may also include only the first segment 401, i.e. the display 4 may be completely rolled up on the roll 3.

Referring to fig. 2 and 3, a portion of the display 4 located to the left of the dotted line is a first segment 401, and another portion of the display 4 located to the right of the dotted line is a second segment 402. One end of the coil spring 6 is fixed to the spool 3, and the other end of the coil spring 6 is fixed to the end of the first section 401 remote from the second section 402. The second section 402 is fixed to the second housing 2. For example, the second section 402 is attached to the second housing 2 by double-sided adhesion.

When the second housing 2 is located at the first position, the display screen 4 has the largest expanded area, and both the first section 401 and the second section 402 are visible areas. When the second housing 2 is in the second position, the display screen 4 has a minimum expanded area, and only the second segment 402 is visible.

When the second casing 2 is at the second position, that is, the electronic device is in the state shown in fig. 1, the second casing 2 can be pulled to the side away from the first casing 1 along the length direction of the first casing 1 by an external force to resist the elastic force of the coil spring 6, so that the first section 401 originally wound on the reel 3 is unwound from the reel 3, and the state is switched to the state shown in fig. 2. When the second housing 2 reaches the first position, the stopper restricts the second housing 2 at the first position to keep the first segment 401 in the unfolded state against the elastic force of the coil spring 6.

When the second housing 2 is in the first position, i.e., the electronic apparatus is in the state shown in fig. 2, the coil spring 6 stores potential energy. The second housing 2 can be pushed to a side close to the first housing 1 along the length direction of the first housing 1 by an external force, so that the limiting member is released from the limitation, the first section 401 originally unwound from the reel 3 is wound on the reel 3 under the action of the coil spring 6, and the state is switched to the state shown in fig. 1. When the second housing 2 reaches the second position, the display screen 4 can be kept in the rolled state by the coil spring 6.

According to the electronic device of the embodiment of the application, by arranging the first casing 1 and the second casing 2 which can slide relatively, the limiting member and the rotatable reel 3 are arranged on the first casing 1, one end of the display screen 4 is connected to the reel 3 through the coil spring 6, and the other end is connected to the second casing 2. So that the display screen 4 can be rolled up by the elastic force of the coil spring 6. When the display screen 4 is in the unfolded state, the second housing 2 can be limited by the limiting member, so that the display screen 4 is limited in the unfolded state. On the basis of meeting the requirement of large-screen display, the electronic equipment has the advantages of reduced volume and convenience in carrying. When the display screen 4 is unfolded or rolled, the thickness of the electronic device is unchanged, and the whole display screen is lighter and thinner. And its simple structure that realizes the rolling of display screen 4 and launch need not the motor and drives spool 3 and rotate or second casing 2 removes, saves the cost, and the rolling of display screen 4 and launch easy operation, user experience is good.

In the embodiment of the present application, the structure of the position limiting element may have various forms. For example, the position-limiting member is a ball telescopically disposed in the first housing 1. Specifically, the first housing 1 is provided with a sliding groove, and the second housing 2 is slidably disposed in the sliding groove. Be equipped with the mounting groove in the spout, the ball passes through the elastic component scalable setting in the mounting groove. The second shell 2 is provided with a limiting groove corresponding to the position of the ball. When second casing 2 was located the first position, the ball stretched out the mounting groove under the effect of elastic component part, and the part that the ball stretched out the mounting groove was located spacing inslot to the realization is spacing to second casing 2. When a certain external force is applied to the second housing 2, the second housing 2 pushes the balls to retract the balls into the mounting groove, so that the limitation on the second housing 2 is removed, the second housing 2 can move to the second position, and the display screen 4 is wound under the action of the coil spring.

As shown in fig. 3, in some embodiments of the present application, the limiting member includes a torsion spring 51. Both ends of the torsion spring 51 are rotatably connected to the first housing 1 and the second housing 2, respectively. With the second housing 2 in the first position, the torsion spring 51 urges the second housing 2 to restrain the second housing 2 in the first position. With the second housing 2 in the second position, the torsion spring 51 urges the second housing 2 to restrain the second housing 2 in the second position.

The torsion spring 51 includes a spring winding, and a first connection pin and a second connection pin connected to the spring winding respectively. The first connecting pin is rotatably connected with the first casing 1, and the second connecting pin is rotatably connected with the second casing 2.

Specifically, a first connecting post 12 is disposed on the first casing 1, and a second connecting post is disposed on the second casing 2. The first connecting pin is sleeved on the first connecting post 12 and can rotate around the first connecting post 12. The second connecting pin is sleeved on the second connecting column and can rotate around the second connecting column. Optionally, the first connecting column 12 and the second connecting column are both provided with a limiting structure 121 for limiting the first connecting pin on the first connecting column 12 and limiting the second connecting pin on the second connecting column. The limiting structure 121 can be a rivet, a screw, or a limiting ring configured on the peripheral side of the first connecting post 12 or the second connecting post.

When the second housing 2 is located at the first position, the torsion spring 51 is located at the position of the torsion spring 51 shown by the solid line in fig. 3. At this time, the elastic force of the torsion spring 51 pushes the second housing 2 in a direction away from the second position, thereby holding the second housing 2 at the first position and preventing the second housing 2 from moving to the second position by a certain external force. If it is necessary to reduce the viewing area of the display screen 4, the second housing 2 may be pushed by hand to move the second housing 2 to the second position against the elastic force of the torsion spring 51, and at the same time, the coil spring 6 winds up the display screen 4.

When the second housing 2 is in the second position, the torsion spring 51 is in the position of the torsion spring 51 shown by the broken line in fig. 3. At this time, the elastic force of the torsion spring 51 urges the second housing 2 in a direction away from the first position, so that the second housing 2 is held at the second position together with the coil spring 6, preventing the second housing 2 from moving toward the first position by a certain external force. If the viewing area of the display 4 is to be enlarged, the second housing 2 can be pulled by hand to move the second housing 2 to the first position against the elastic force of the torsion spring 51 and the elastic force of the coil spring 6, so as to unfold the display 4.

By arranging the torsion spring 51, the embodiment of the application can reliably limit the second shell 2 at the first position when the second shell 2 is at the first position, and can also reliably limit the second shell 2 at the second position under the combined action of the torsion spring 6 when the second shell 2 is at the second position, thereby improving the stability of the state of the display screen 4 of the electronic device.

The two torsion springs 51 are symmetrical to each other about the center line of the first housing 1. Wherein, the direction of the central line of the first shell 1 is consistent with the length direction of the first shell 1. The two torsion springs 51 are located on two sides of the center line, and are symmetrically distributed. Therefore, the second shell 2 can be stressed more uniformly in the width direction of the first shell 1, and the second shell 2 can slide more smoothly.

Optionally, the inner side wall of the first housing 1 facing the second housing 2 is provided with a sinking groove 14, and the torsion spring 51 is disposed in the sinking groove 14, so that the occupation of the torsion spring 51 on the space between the first housing 1 and the second housing 2 can be reduced, and the electronic device is light and thin.
