In order to make those skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and "third," etc. in the description and claims of this application and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 1, fig. 1 is a partial schematic structural diagram of an electronic device 100 in a retracted state according to an embodiment of the present disclosure. In this embodiment, the electronic device 100 is a mobile phone. It is understood that, in other embodiments, the electronic device 100 may also be a tablet computer, a notebook computer, a desktop computer, a television, a personal digital assistant, or other electronic devices with a retractable device.

Referring to fig. 2, fig. 2 is a disassembled schematic view of an electronic device 100 according to an embodiment of the present application. The electronic device 100 includes a middle frame 10 and a telescopic device 30. The telescopic device 30 is disposed on the middle frame 10. It is understood that the electronic device 100 further includes electronic components, such as a processor, a memory, a battery, a display screen, and the like, and structural components, such as a front case, a rear case, and the like, which are not related to the invention of the present application and thus will not be described in detail.

Referring to fig. 3, fig. 3 is a disassembled schematic view of the expansion device 30 according to an embodiment of the present application. The telescopic device 30 comprises a driving member 31, a rotor 32, a sliding block 33, a first connecting line 34 and a second connecting line 35. The driving member 31 is disposed on the middle frame 10. The drive member 31 is connected to the rotor 32. The slider 33 has opposite first and

second ends

331 and 333. One ends of the first connection line 34 and the second connection line 35 are connected to the rotor 32, respectively. The other end of the first connecting wire 34 is connected to the first end 331 of the slider 33. The other end of the second connecting wire 35 is connected to the second end 333 of the slide block 33. When the driving member 31 rotates forward to drive the rotor 32 to rotate and further drive the first connecting line 34 to wind on the rotor 32, the sliding block 33 slides relative to the middle frame 10 and is in an extended state. When the driving member 31 rotates reversely to drive the rotor 32 to rotate and further drive the second connecting wire 35 to wind on the rotor 32, the sliding block 33 slides relative to the middle frame 10 and is in a retracted state.

It is understood that the "forward rotation" refers to one of clockwise rotation and counterclockwise rotation, and drives the sliding block 33 to slide out relative to the middle frame 10. The reverse rotation is a rotation in the opposite direction to the forward rotation and drives the slide block 33 to retract with respect to the middle frame 10. In this embodiment, since the driving member 31 is disposed on the right side of the sliding block 33, the forward rotation is clockwise rotation. It will be appreciated that in other embodiments, if the driving member 31 is disposed on the left side of the sliding block 33, the forward rotation may be counterclockwise.

Therefore, the driving member 31 drives the rotor 32 to rotate, so as to drive the first connecting line 34 and the second connecting line 35 to move together along with the rotation of the rotor 32, so as to drive the sliding block 33 to switch between the extending state and the retracting state, and the telescopic structure is simpler and more reliable, and the cost is lower.

Further, the rotor 32 is located between the first end 331 and the second end 333. When the driving member 31 rotates forward to drive the rotor 32 to rotate and drive the first connecting line 34 to wind on the rotor 32, the rotation of the rotor 32 also releases the second connecting line 35 from the rotor 32, so that the sliding block 33 is not restrained by the second connecting line 35 in the extending process. When the driving member 31 rotates reversely to drive the rotor 32 to rotate and further drive the second connecting wire 35 to wind on the rotor 32, the rotation of the rotor 32 also releases the first connecting wire 34 from the rotor 32, so that the sliding block 33 is not held by the first connecting wire 34 during the retraction process. That is, whether the driving member 31 rotates in the forward direction or in the reverse direction, the driving member 31 winds the first connecting wire 34 around the rotor 32 by a length equal to a length of the second connecting wire 35 released from the rotor 32. The length of the first connecting line 34 released by the driving member 31 on the rotor 32 is equal to the length of the second connecting line 35 wound on the rotor 32.

Therefore, the driving member 31 drives the first connecting line 34 and the second connecting line 35 to move cooperatively, so as to drive the sliding block 33 to switch between the extended state and the retracted state, and the telescopic structure is simpler and more reliable, and the cost is lower.
