The following is a description with examples:

Example 1: Referring to Figure 3, the first sleeve 201 and the second sleeve 202 are both fan-shaped cylinders, the second sleeve 202 can be sleeved in the first sleeve 201, and the first wire 311 is arranged in the first sleeve On the side wall AEJF of 201 (that is, the rectangular side wall of the first sleeve), the first coil 321 is disposed on the side wall ACIF of the second sleeve 202 (that is, the rectangular side wall of the second sleeve). The first wire 311 is parallel to the connection axis AF (that is, the first axis) between the first sleeve 201 and the second sleeve 202, and the distance between the first wire 311 and the connection axis AF and the first coil 321 and the connection axis The distances of AF are the same. In the following description, the distance between the first wire 311 and the connecting axis AF and the distance between the first coil 321 and the connecting axis AF are both the radius of the sleeve.

When the current I0 is applied to the first wire 311, a magnetic field will be generated around the first wire 311, and the first coil 321 can generate induced current or induced electromotive force, which can be obtained based on the induced current or induced electromotive force. Magnetic induction intensity B, and then the relative position of the two can be determined according to the relationship between B0 and I0. Specifically, when the length l of the first wire 311 is much greater than the spreading distance r ₀ between the sleeves (that is, l>>r ₀ ), the first wire 311 may be equivalent to an infinite length relative to the tiny gap in the sleeve. , According to the ampere loop rule, the magnetic induction intensity B0 is generated at the radius r ₀ of the first wire 311:

Among them, I ₀ represents the current flowing through the first wire 311, μ ₀ represents the vacuum permeability, r ₀ represents the distance between the first wire 311 and the second coil 312, and B0 represents the detected value through the first coil 321 Magnetic induction.

If the sleeve radius is R0, that is, the distance between the first wire 311 and the connecting shaft AF is R0, the angle θ1 between the first sleeve 201 and the second sleeve 202 is the same as the first sleeve 201 and the second sleeve. The relationship between the linear distance r ₀ between the cylinders 202 (that is, the distance between the first wire 311 and the first coil 321) may be as follows:

In summary, the relationship between the angle θ0 between the first sleeve 201 and the second sleeve 202 and the magnetic induction intensity B0 can be as follows:

If the number of sleeves is N, the expansion angle α0 of the hinge (that is, the folding angle of the folding screen) can be calculated according to the following formula:

Example 2: Referring to Figure 4, the first sleeve 201 and the second sleeve 202 are both fan-shaped cylinders, the second sleeve 202 can be sleeved in the first sleeve 201, and the second coil 312 is arranged in the first sleeve On the side wall AEJF of 201, the first coil 321 is arranged on the side wall ACIF of the second sleeve 202. The distance between the second coil 312 and the connecting axis AF is the same as the distance between the first coil 321 and the connecting axis AF, and the height of the center of the second coil 312 and the first coil 321 may be the same.

When the current I1 is applied to the second coil 312, a magnetic field will be generated around the second coil 312. The first coil 321 can generate induced current or induced electromotive force, which can be obtained based on the induced current or induced electromotive force. Magnetic induction intensity B, and then the relative position of the two can be determined according to the relationship between B and I. Specifically, when the current I1 passes through the second coil 312, the magnetic induction intensity B1 along the central axis of the ring can be as follows:

Among them, I ₁ represents the current flowing through the second coil 312, μ ₀ represents the vacuum permeability, r ₁ represents the distance between the first coil 321 and the second coil 312, a represents the radius of the second coil 312, and B1 represents The magnetic induction intensity detected by the first coil 321.

If the distance between the center of the second coil and the connecting axis AF is R1, the relationship between the angle θ1 between the sleeves and the linear distance r1 of the two hinges can be as follows:

If the number of sleeves is N, the expansion angle α1 of the hinge (that is, the folding angle of the folding screen) can be calculated according to the following formula:

It can be seen from the above that the magnetic induction intensity B1 at the position of the second coil is inversely proportional to the linear distance r1 between the two. Therefore, the magnetic induction intensity decreases rapidly with the expansion angle, and higher sensitivity and resolution can be obtained.

In the embodiment of the present disclosure, the first wall is a rectangular side wall of the first sleeve, the second wall is a rectangular side wall of the second sleeve, and the electromagnetic field generating element is connected to the first shaft The distance is the same as the distance between the magnetic induction signal detection element and the first axis, which can simplify calculation complexity and improve the efficiency of folding angle detection.

In the embodiment of the present disclosure, when the first sleeve is sleeved with the second sleeve, the center point of the second coil coincides with the orthographic projection of the center point of the first coil, and the magnetic induction generated by the first coil The signal (for example, induced current) is the strongest. When the angle between the first sleeve and the second sleeve becomes larger, the overlapping area of the second coil and the first coil decreases, and the first coil The generated magnetic induction signal (for example, induced current) becomes weak, so that the angle between the first sleeve and the second sleeve can be determined according to the magnetic induction signal generated by the first coil.

Optionally, when the first sleeve and the second sleeve are both fan-shaped cylinders, the electromagnetic field generating element includes the second coil and the magnetic induction signal detection element includes the first coil Next, the first wall can be a top wall, a bottom wall or an arc-shaped side wall of the first sleeve.

The first coil 321 is provided with a first contact and a first ground contact, wherein the first coil 321 is connected to GPIO through the first contact, and grounded to GND through the first ground contact. Wherein, the aforementioned GPIO may be a GPIO of an electronic device.

In practical applications, when the second coil 312 is energized through the power supply V0, the magnetic induced electromotive force induced by the first coil 321 can be transmitted to the GPIO. After sampling by the ADC module, the preset induced electromotive force and included angle can be searched Correspondence between the two, the expansion angle between the first sleeve 201 and the second sleeve 202 at this time can be obtained, and then the expansion angle of the hinge, that is, the folding angle of the folding screen can be obtained.

In the embodiments of the present disclosure, the electromagnetic field generating element includes the second coil and the magnetic induction signal detecting element includes the first coil, so that the folding angle measurement can be realized at a lower cost and has a higher resolution.

It should be noted that the foregoing preset calculation formula may correspond to the location of the electromagnetic field generating element and the magnetic induction signal detecting element, the type of the electromagnetic field generating element, and the like.
