When the two frames 21 rotate relative to each other and are in a folded state, the electromagnet 232 and the magnetic suction member 231 are mutually attracted to each other so that the folding shell 20 remains in a folded state; the switch mechanism 25 is movably arranged in one of the frames 21, and the switch mechanism 25 is used to control the power on or off of the electromagnet 232. When the switch mechanism 25 is displaced to the first position, the electromagnet 232 is energized to reduce the magnetic attraction between the electromagnet 232 and the magnetic suction member 231, or the electromagnet 232 and the magnetic suction member 231 have a mutually repelling magnetic force. Optionally, the folding shell 20 further includes a folding mechanism 22, and the two frames 21 are rotatably connected to the opposite sides of the folding mechanism 22, and the two frames 21 can be folded or flattened with each other through the folding mechanism 22; in this embodiment, the folding mechanism 22 is a hinge, and the two frames 21 can be folded or flattened with each other through the hinge.

The circuit main board 60 is provided with a processor 62, a memory 64, a sensor 65 and a power supply (not shown in the figure). The power supply is used to power the circuit main board 60 and the flexible screen 40. The processor 62 is electrically connected to the memory 65 and the sensor 65. The sensor 65 is used to sense the change in the intensity of the magnetic flux lines around the first magnetic field and send a signal to the processor 62. The processor 62 receives the signal and controls the electromagnet 232 to be powered on or off, thereby changing the second magnetic field intensity around the electromagnet 232, so that the magnetic attraction between the electromagnet 232 and the magnetic suction member 231 changes; or changing the current direction of the electromagnet 232 to change the polarity direction of the electromagnet 232, so that the polarity directions of the electromagnet 232 and the magnetic suction member 231 are opposite and repel each other. Optionally, the processor 62, the memory 64 and the sensor 65 are respectively connected to the circuit main board 60 by SMT patch technology.

[0050] It is understandable that the processor 62 may include one or more processing cores. The processor 62 uses various interfaces and lines to connect various parts within the electronic device 100, and executes various functions and processes data of the electronic device 100 by running or executing instructions, programs, code sets or instruction sets stored in the memory 64, and calling data stored in the memory 64. Optionally, the processor 62 can be implemented in at least one hardware form of digital signal processing, field programmable gate array, and programmable logic array.

[0054] The magnetic attraction between the two frames of the folding electronic device in the prior art is relatively large. When unfolding the electronic device, the user cannot open it with one hand due to the lack of strength. Usually, the user needs to use both hands to achieve it. In some scenarios, such as when one of the user's hands is occupied, the user cannot or is not convenient to unfold the folding electronic device with only the other hand. In view of the above-mentioned problem that the existing folding electronic device cannot be unfolded or folded with one hand, a magnetic attraction member 231 is provided on one frame 21 of the electronic device 100 of the present invention, and an electromagnet 232 is provided on the other frame 21. When the electronic device 100 needs to be unfolded, the user can hold the electronic device 100 with one hand and operate the switch mechanism 25 to move to the first position relative to the frame 21, so that the electromagnet 232 is energized to reduce the magnetic field strength around the electromagnet 232, and the magnetic attraction between the electromagnet 232 and the magnetic attraction member 231 is reduced; or after the electromagnet 232 is energized, the polarities of the electromagnet 232 and the magnetic attraction member 231 are opposite and repel each other, so that the user can hold and unfold the electronic device 100 with one hand, which is convenient to operate and improves the user experience.

[0069] Please also read Figure 1-Figure 4 and Figure 23-Figure 26 When the electronic device 100 is in a folded state, the two frames 21 are folded against each other, the bendable area 41 of the flexible screen 40 is bent into a teardrop shape, and the two non-bending areas 43 are folded against each other; the polarities of the surfaces facing each other of the electromagnet 232 and the magnetic attraction member 231 are opposite and they are magnetically attracted to each other, that is, the magnetic core 234 and the magnetic attraction member 231 are attracted to each other. At this time, the switch mechanism 25 is reset to the second position, the coil 237 is in a power-off state, the attraction between the electromagnet 232 and the magnetic attraction member 231 is greater than the unfolding elastic force of the elastic member 222, and the electronic device 100 is in a stable folded state.

[0070] Please also read Figure 1-Figure 4 and Figure 27-Figure 32When the user holds the electronic device 100 in one hand and needs to unfold it, the user pushes the operating member 254 with his finger to slide along the avoidance groove 2142 toward the end close to the first magnet 2531, and the operating member 254 drives the sliding member 252 to slide toward the first magnet 2531 to the first end 2126a, the switch bracket 250 is located in the first position, the second magnet 2533 slides to the first position with the sliding member 252, and the second magnet 2533 is close to the first magnet 2531. The sensor 65 senses the change in the intensity of the magnetic flux lines around the first magnetic field and sends a first signal to the processor 62 of the circuit board 60, and the circuit board 60 receives the first signal And control the electromagnet 232 to be energized, the coil 237 generates magnetic flux lines opposite to the magnetic core 234 to offset the strength of the magnetic flux lines generated by the magnetic core 234, so that the overall magnetic field strength of the electromagnet 232 is reduced, thereby reducing the magnetic attraction between the electromagnet 232 and the magnetic suction member 231, and the user only needs a small unfolding thrust and combined with the unfolding elastic force of the elastic member 222 to unfold the two frames 21; optionally, when the magnetic attraction between the electromagnet 232 and the magnetic suction member 231 is less than the unfolding elastic force provided by the elastic member 222, the two frames 21 automatically unfold to each other at an angle, so that the user can open the electronic device 100 with one hand. In some embodiments, it can also be configured that when the electromagnet 232 is energized, the magnetic attraction between the electromagnet 232 and the magnetic suction member 231 is less than the unfolding elastic force driven by the elastic member 222 to drive the two frames 21, so that the two frames 21 can be automatically unfolded. When the two frames 21 are unfolded, the user releases the thrust on the operating member 254. Since the first magnet 2531 and the second magnet 2533 have the same polarity, they repel each other and drive the sliding member 252 to slide along the guide groove 2126 to the second end 2126b. The second magnet 2533 slides to the second position with the sliding member 252. The switch bracket 250 is located in the second position. The second magnet 2533 is away from the first magnet 2531. The sensor 65 senses the change in the strength of the magnetic flux lines around the first magnetic field and sends a second signal to the circuit main board 60. The circuit main board 60 controls the electromagnet 232 to cut off the power, and the second magnetic field strength around the electromagnet 232 is restored.

[0071] In other embodiments, the switch mechanism 25 can also be replaced by a voice recognition module, which is used for voice recognition and sends the unfolding instruction to the circuit main board 60; when the electronic device 100 is in a folded state, the voice recognition module recognizes the voice and sends the unfolding instruction to the circuit main board 60, and the circuit main board 60 receives the unfolding instruction and controls the electromagnet 232 to charge, so that the second magnetic field strength around the electromagnet 232 is reduced, and the magnetic attraction between the electromagnet 232 and the magnetic suction member 231 is reduced. The user only needs a small unfolding thrust and combines the unfolding elastic force of the elastic member 222 to unfold the two frames 21, which is convenient to use. Or after the electromagnet 232 is energized, the electromagnet 232 and the magnetic suction member 231 can have the same polarity and repel each other, and automatically unfold under the action of the elastic member 222.

The user only needs a small unfolding thrust and the unfolding elastic force of the elastic member 222 to unfold the two frames 21, which is convenient to use. Or after the electromagnet 232 is energized, the electromagnet 232 and the magnetic suction member 231 can have the same polarity and repel each other, and under the action of the elastic member 222, the two frames 21 are rotated relative to each other and away from each other, and the two frames 21 drive the flexible screen 40 to unfold automatically until the flexible screen 40 unfolds to a flat state.

[0073] The electronic device 100 can be an inner folding screen device or an outer folding screen device. In the present embodiment, the electronic device 100 is an inner folding screen device, that is, when the electronic device 100 is in the folded state, the two non-bending areas 43 of the flexible screen 40 are parallel to and in contact with each other. When the electronic device 100 is in the unfolded state, the non-bending areas 43 on the two frames 21 of the electronic device 100 are coplanar. When the electronic device 100 changes from the unfolded state to the folded state, the two frames 21 are brought closer to each other through the folding mechanism 22, and the elastic member 222 is elastically bent until the non-bending areas 43 on the two frames 21 are parallel to and in contact with each other, so that the bendable area 41 of the flexible screen 40 is in a U-shaped or teardrop-shaped folded state. The elastic member 222 has a certain damping during the folding or unfolding process of the electronic device 100. In other embodiments, the electronic device 100 may be an external folding screen device. In the folded state, the two non-bending areas 43 of the flexible screen 40 face away from each other; in the unfolded state, the non-bending areas 43 on the two frames 21 are coplanar with the non-bending areas 43 on the folding mechanism 22, so that the flexible screen 40 is in a planar unfolded state; in the process of the electronic device 100 changing from the unfolded state to the folded state, the two frames 21 are brought closer to each other through the folding mechanism 22, and in the folded state, the non-bending areas 43 on the two frames 21 are parallel to each other, so that the flexible screen 40 is in a U-shaped folded state.

[0074] In some embodiments, the electronic device 100 may further include multiple frames, each adjacent two frames are connected by a folding mechanism 22, and accordingly, the flexible screen 40 includes multiple non-bending areas 43 and a bendable area 41 connected between each adjacent two non-bending areas 43, and the multiple bendable areas 41 correspond one-to-one to the multiple folding mechanisms 22 respectively; a magnetic suction component 23 is provided between each adjacent two frames, and a switch mechanism 22 can simultaneously control the electromagnets 232 in multiple magnetic suction components 23 to be energized or de-energized, so as to realize the synchronous unfolding of multiple frames.

[0075] Optionally, the electronic device 100 is further provided with at least one other component, which includes but is not limited to a fingerprint sensor, a proximity light sensor, a distance sensor, a camera, etc.

[0076] Optionally, the switch mechanism 22 of the electronic device 100 may also be disposed on the front surface 211 , the back surface 212 or the end surface 215 of the frame body 21 .

[0077] In other embodiments, a touch sensor is provided on the outer surface of the frame 21, and the touch sensor is used to detect at least one of a touch operation, a click operation, a press operation, and a slide operation performed by a user on the frame 21. The touch sensor can be any one of a touch sensor, a thermal sensor, a pressure sensor, etc. The user can apply an operation on the touch sensor to control an application in the electronic device 100.

[0078] Optionally, the electronic device 100 also includes components such as a radio frequency circuit, an input unit, a sensor, an audio circuit, a wireless fidelity module, a power supply, and a Bluetooth module, which are not described in detail here.

[0079] See also Fig.33 , Fig.33 FIG. 1 is a flowchart of a method for unfolding an electronic device 100 provided in one exemplary embodiment of the present application. The method for unfolding an electronic device 100 includes:

[0080] Step 201: Detect the state of the electronic device 100.

[0081] Specifically, the flexible screen 40 may be in a folded state or an unfolded state, wherein the folded state refers to the flexible screen 40 being folded into a U-shape or a teardrop shape, the two non-bending regions 43 being parallel to each other and the light-emitting surfaces facing each other, and the flexible screen 40 is in a non-display state. The unfolded state of the flexible screen 40 is that the two non-bending regions 43 of the flexible screen 40 and the bendable region 41 are coplanar.

[0082] Step 203: When the electronic device 100 is in the folded state, the circuit board 60 receives the first signal sent by the sensor 65 and controls the electromagnet 232 to be energized, so that the magnetic attraction of the second magnetic field around the electromagnet 232 is reduced, or the electromagnet 232 has a magnetic force that repels the magnetic attraction component 231.

[0083] Specifically, the user pushes the operating member 254 to slide along the avoidance groove 2142 toward the end close to the first magnet 2531, so that the switch bracket 250 slides to the first position, and the second magnet 2533 approaches the first magnet 2531 with the switch bracket 250, and the sensor 65 senses the change in the strength of the magnetic flux lines around the first magnetic field and sends a first signal to the circuit main board 60. The circuit main board 60 receives the expansion instruction and controls the electromagnet 232 to be energized, so that the magnetic attraction of the second magnetic field around the electromagnet 232 is reduced, and the magnetic attraction between the electromagnet 232 and the magnetic attraction member 231 is reduced. The attraction is weakened, which makes it easier for the user to use a smaller unfolding thrust with one hand and combine with the unfolding elastic force of the elastic member 222 to unfold the two frames 21; or, the sensor 65 senses the change in the strength of the magnetic flux lines around the first magnetic field and sends a first signal to the circuit main board 60. The circuit main board 60 receives the unfolding instruction and controls the electromagnet 232 to be energized so that the polarity of the electromagnet 232 is opposite to the polarity of the magnetic attraction member 231. The mutual repulsive force between the electromagnet 232 and the magnetic attraction member 231 and the unfolding elastic force of the elastic member 222 can automatically unfold the two frames 21.

[0084] like Fig.34 As shown, optionally, the electronic device 100 deployment method further includes:

[0085] Step 201: Detecting the state of the electronic device 100;

[0086] Step 205: When the electronic device 100 is in the flattened state, the circuit board 60 receives the second signal sent by the sensor 65 and controls the electromagnet 232 to be powered off, so that the coil of the electromagnet 232 is non-magnetic.

[0087] The user releases the pushing force on the operating member 254 to automatically reset the switch bracket 250 to the second position. The second magnet 2533 moves away from the first magnet 2531 along with the switch bracket 250. The sensor 65 senses the change in the strength of the magnetic flux lines around the first magnetic field and sends a second signal to the circuit main board 60. The circuit main board 60 receives the instruction and controls the electromagnet 232 to cut off the power, so that the coil of the electromagnet 232 is non-magnetic, and the second magnetic field strength around the electromagnet 232 is restored.

[0088] like Fig.35As shown, the structure of the folding shell 20a in another embodiment of the present application is similar to the structure of the folding shell 20 in any of the above embodiments, except that: the structure of the magnetic attraction component 23a in the folding shell 20a is different from the structure of the electromagnet 23 in the folding shell 20. Specifically, the structure of the electromagnet 232a in the magnetic attraction component 23a is different from the structure of the electromagnet 232 in the magnetic attraction member 231. The electromagnet 232a includes an iron core 238, a coil support 236 sleeved on the iron core 238, and a multi-turn coil wound around the coil support 236. After the coil is energized, the magnetic polarity of the electromagnet 232a can be the same as the magnetic polarity of the magnetic attraction member 231, so that the electromagnet 232a and the magnetic attraction member 231 repel each other and the two frames 21 are unfolded under the action of the unfolding elastic force of the elastic member 222.

[0089] Specifically, when the electronic device is in the folded state, the user holds the electronic device 100 with one hand and pushes the operating member 254 to slide along the avoidance groove 2142 toward the end close to the first magnet 2531, so that the switch bracket 250 slides to the first position, and the second magnet approaches the first magnet 2531 with the switch bracket 250. The sensor 65 senses the change in the strength of the magnetic flux lines around the first magnetic field and sends a signal to the circuit main board 60. The circuit main board 60 receives the unfolding instruction and controls the electromagnet 232 to be energized so that the magnetic polarity of the electromagnet 232 is the same as the magnetic polarity of the magnetic attraction component 231. The mutual repulsive force between the electromagnet 232a and the magnetic attraction component 231 combined with the unfolding elastic force of the elastic component can cause the two frames 21 to unfold automatically. When the user releases the pushing force on the operating member 254, the first magnet 2531 and the second magnet repel each other due to their same polarity, driving the switch bracket 250 to reset to the second position. The second magnet slides to the second position with the switch bracket 250, and the second magnet moves away from the first magnet 2531. The sensor 65 senses the change in the strength of the magnetic flux lines around the first magnetic field and sends a second signal to the circuit main board 60. The circuit main board 60 controls the electromagnet 232a to cut off the power. At this time, the electromagnet 232a is non-magnetic.

[0090] The method for unfolding the folding housing 20a in another embodiment is the same as the method for unfolding the folding housing 20 in one of the above embodiments, and thus will not be described in detail herein.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
