In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
Technical solutions disclosed in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, the present application provides an electronic device, which includes a flexible display screen, a first folding body 1 and a second folding body 2, wherein the first folding body 1 and the second folding body 2 are rotatably connected, the flexible display screen is partially connected to the first folding body 1, and partially connected to the second folding body 2, and the flexible display screen can be folded or unfolded by rotating the first folding body 1 and the second folding body 2. The electronic equipment can bring new visual experience to consumers through the expanded large screen.
Specifically, referring to fig. 1, the electronic device further includes a magnetic induction sensor 3 and a plurality of magnets 4. Fixedly connected with pivot 11 on the first folder 1, each magnet 4 winds the circumferencial direction evenly distributed of pivot 11, and with pivot 11 fixed connection, second folder 2 rotationally connect in pivot 11, magnetic induction sensor 3 set up in on the second folder 2. In the process that the second folding body 2 rotates relative to the first folding body 1, the magnets 4 are sequentially opposite to the magnetic induction sensor 3, and the magnetic induction sensor 3 determines the angle of the second folding body 2 relative to the first folding body 1 according to the opposite times of the magnets 4.
In this embodiment, in the process of folding the electronic device, the rotating shaft 11 rotates relative to the magnetic induction sensor 3, so that the different magnets 4 sequentially oppose the magnetic induction sensor 3, the magnetic induction sensor 3 is magnetized to enable the magnetic induction sensor 3 to generate corresponding induction signals, and the magnetic induction sensor can calculate the folding or unfolding angle of the electronic device according to the number of times of the generated induction signals. Compared with the scheme of detecting the folding angle of the electronic equipment through the optical sensor, the electronic equipment is simple in structure, low in cost and high in angle detection precision.
It should be noted that the term "the magnet 4 is fixedly connected to the rotating shaft 11" in the embodiment of the present application may be understood that the magnet 4 is directly connected to the rotating shaft 11, and may also be understood that the magnet 4 is indirectly connected to the rotating shaft 11 through other components. As long as the rotation of the rotating shaft 11 can drive the magnet 4 to rotate integrally.
For example: each magnet 4 may be directly attached to the surface of the rotating shaft 11 around one circumference of the rotating shaft 11, or may be embedded in the rotating shaft 11. The magnet 4 may be a block or a magnetic material layer attached to the surface of the rotating shaft 11.
Considering that the diameter of the rotating shaft 11 is small, it is inconvenient to arrange the magnet 4, and the rotating shaft 11 is far away from the magnetic induction sensor 3, which is not beneficial for the magnet 4 to magnetize the magnetic induction sensor 3. Referring to fig. 1, the electronic device provided in the embodiment of the present application further includes a magnetic carrier component 5. The magnetic carrier component 5 is coaxially arranged with the rotating shaft 11 and is fixedly connected with the rotating shaft 11; the magnets 4 are provided on the magnetic carrier member 5 at intervals in the circumferential direction of the magnetic carrier member 5. I.e. each magnet 4 is indirectly connected to the shaft 11 via the magnetic carrier part 5. The diameter of the magnetic carrier part 5 may be larger than the diameter of the shaft 11, thereby facilitating the approach of the magnet 4 to the magnetic induction sensor 3. The magnetic carrier member 5 can be attached to the end of the rotating shaft 11 without occupying an internal space, thereby not affecting the installation of the flexible display screen.
In one possible embodiment, the magnetic carrier member 5 is provided with a plurality of protrusions 51 at intervals in the circumferential direction, and each of the magnets 4 is provided on the protrusions 51.
In this embodiment, the protrusions 51 are evenly distributed in the circumferential direction of the magnetic carrier member 5, and the magnet 4 is disposed on the protrusions 51 closer to the magnetic induction sensor 3, facilitating magnetization of the magnetic induction sensor 3. And each protrusion 51 on the magnetic carrier part 5 is the setting position of the magnet 4, which is convenient for setting the magnet 4 on the magnetic carrier part and is beneficial to improving the production efficiency.
In one possible embodiment, shown in fig. 1, the protrusions 51 are pointed structures that taper radially outward of the magnetic carrier part 5; the magnet 4 is disposed at the pointed end of the projection 51. Optionally, the magnet 4 is a layer of magnetic material disposed on the pointed end of the protrusion 51.
In this embodiment, the magnetic carrier member 5 has a gear-like cross section, each protrusion 51 has a sharp-angled structure, a magnetic material layer is disposed on the sharp-angled end of the protrusion 51, the magnetic material layer has a small volume and a small occupied area, and a recess is formed between the magnetic material layers on adjacent protrusions 51. The smaller the structure of the magnet 4 is, the smaller the magnetization interference of each magnet 4 to the magnetic induction component is, so that when the protrusion 51 on the magnetic carrier component 5 is just opposite to the magnetic induction sensor 3, the magnetic induction sensor 3 can be magnetized to generate an induction signal, and when the protrusion 51 is staggered with the magnetic induction sensor 3, the magnetic induction sensor 3 can be demagnetized to generate another signal, thereby being beneficial to accurately detecting the folding or unfolding angle of the electronic equipment.
In addition, the magnetic carrier member 5 may have a cylindrical structure, and the magnets 4 are arranged in sequence and uniformly distributed along the circumferential direction of the magnetic induction member. One end of each magnet 4 is connected with the surface of the magnetic carrier part 5, the other end extends outwards along the radial direction of the magnetic carrier part 5, and the whole magnet 4 is in a sharp-angled structure or tooth shape. The structural design increases the volume of the magnet 4 and enhances the magnetization effect of the magnet 4 on the magnetic induction sensor 3.
Referring to fig. 2, in a possible embodiment, the magnetic induction sensor 3 includes a first elastic sheet 31 and a second elastic sheet 32 which are arranged at intervals;

When the magnet 4 is not aligned with the magnetic induction sensor 3, the first elastic sheet 31 and the second elastic sheet 32 are separated.
Optionally, the first elastic sheet 31 includes a straight section and an inclined section, and the inclined section is connected to the straight section and inclines to a side far away from the magnetic induction sensor 3; the second elastic sheet 32 is arranged between the inclined section and the magnetic induction sensor 3, and the end part of one side, corresponding to the inclined section, of the second elastic sheet 32 is provided with a conductive coating. When the first elastic sheet 31 is deviated to the direction of the magnet, the conductive coating of the first elastic sheet 31 is in contact conduction with the conductive coating of the second elastic sheet 32.
The electronic equipment comprises a first detection circuit, the first elastic sheet 31 and the second elastic sheet 32 are electrically connected with the first detection circuit, when the first elastic sheet 31 contacts with the second elastic sheet 32, the first detection circuit is switched on, and when the first elastic sheet 31 is separated from the second elastic sheet 32, the first detection circuit is switched off. The electronic device further comprises a processor, the processor is connected with the first detection circuit, the processor counts when the first detection circuit is switched on, and determines the rotation angle of the second folding body 2 relative to the first folding body 1 according to a count value. Referring to fig. 2 and 3, the magnetic carrier member 5 is formed of a non-magnetic material except for the magnet 4. The electronic equipment comprises a circuit board, and the first detection circuit comprises a GND interface, a third resistor and a third GPIO interface which are arranged on the circuit board. The first elastic sheet 31 of the magnetic induction sensor 3 is connected with the GND interface, the second elastic sheet 32 of the magnetic induction sensor 3 is connected with a high level (such as 1.8V) on the circuit board through a third resistor, a circuit between the third resistor and the second elastic sheet 32 is connected with a third GPIO interface, and the processor can determine the folding or unfolding angle of the electronic device by judging the high and low level state of the third GPIO interface.
When the magnetic carrier part 5 rotates to a certain magnet 4 to face the magnetic induction sensor, the two elastic pieces of the magnetic induction sensor 3 are in closed contact, and at the moment, the third GPIO interface is at a low level. When the magnetic carrier part 5 rotates to the magnet 4 and staggers the magnetic induction sensor 3, namely the concave part between the two magnets 4 is right opposite to the magnetic induction sensor 3, the two elastic sheets are demagnetized and restored to be deformed and separated from each other, and the third GPIO is at a high level. The processor can judge that the magnetic carrier part 5 rotates for 1 time at the moment through the high and low levels, so that the folding angle of the electronic device can be calculated, wherein the corresponding relation between the low level times of the third GPIO interface and the folding or unfolding angle is as follows:
the electronic equipment provided by the embodiment of the application can detect the folding direction besides the rotation angle, namely can detect whether the electronic equipment is in a folding process or a separating and unfolding process.
Specifically, referring to fig. 4, the electronic device further includes a folding direction detection mechanism.

In one possible embodiment, the electronic device includes a shaft sleeve (not shown) sleeved on the rotating shaft; an elastic member (not shown) is provided between the sleeve and the rotating shaft 11; the conductive member is disposed on the boss. In the process of folding or unfolding the electronic device, the conductive part abuts against the grounding terminal, at this time, the rotating shaft 11 continues to rotate, the conductive part cannot rotate along with the rotating shaft 11 all the time, and in the process of continuing to rotate the rotating shaft 11, the elastic part is compressed to further deform. Wherein the resilient member may be a coil spring. The inner end of the coil spring is connected with the rotating shaft 11, and the outer end of the coil spring is connected with the shaft sleeve. The rotation of the shaft 11 drives the shaft sleeve and the conductive component to rotate through the elastic component.
In one possible embodiment, the conductive members comprise a first conductive member 6 and a second conductive member 7. The first conductive member 6 and the second conductive member 7 are alternately arranged, and the ground terminal includes a first ground terminal 101 and a second ground terminal 102 arranged at an interval.
