Specifically, the structure of the second eddy current sensor 22 is the same as that of the first eddy current sensor 21, and since the detailed description is given in the above embodiments, the detailed description is omitted in the embodiments of the present application in view of the brevity of the text.
In the embodiment of the application, the two eddy current sensors can assist a user in unfolding or folding the electronic equipment, so that the user can use the electronic equipment more conveniently, and the user experience is enhanced.
Namely, bias voltage is superposed on the basis of alternating current excitation voltage to generate attraction or repulsion, eddy current excitation voltage with auxiliary function is applied to two eddy current sensors in the process of folding the electronic equipment, and then reverse bias magnetic field is excited, so that attraction is generated, and when the electronic equipment is folded, attraction is continuously generated to play a role in resisting rebound; when the electronic equipment is unfolded, the two eddy current sensors are applied with the same-direction bias voltage, and then the same-direction bias magnetic field is excited, so that the repulsive force is generated.

When the folding screen of the electronic device is not completely unfolded, such as being unfolded by a certain angle or being completely folded, the surface where the perpendicular line of the connecting line of the two eddy current sensors is located passes through the bending part 13, so that the unfolding or folding of the folding screen can be better assisted.
In one possible embodiment of the present application, in the case where the end of the first portion 11 facing away from the bend 13 and the end of the second portion 12 facing away from the bend 13 are close to each other, the first eddy current sensor 21 and the second eddy current sensor 22 operate with a reverse bias voltage; in the case where the end of the first part 11 facing away from the bent part 13 and the end of the second part 12 facing away from the bent part 13 are away from each other, the first eddy current sensor 21 and the second eddy current sensor 22 operate with the same bias voltage.

The opening of the auxiliary function can reduce the force applied by a user in unfolding and folding the folding screen electronic equipment, and better assist the user in operating and using the folding screen electronic equipment.
The embodiment of the application also provides a folding angle detection method of the electronic equipment, and the electronic equipment comprises a folding screen. As shown in fig. 5, the folding angle detection method of the electronic device may include: contents shown in step S501 to step S502.
In step S501, an induced voltage variation of a first eddy current sensor disposed on a folding screen is obtained.
In step S502, the folding angle of the folding screen is determined according to the induced voltage variation.
In the embodiment of the application, the variation of the induced voltage of the first eddy current sensor arranged on the folding screen is firstly obtained, and then the folding angle of the folding screen is determined according to the variation of the induced voltage. The embodiment of the application can detect the change of the folding angle of the folding screen through the eddy current sensor arranged on the folding screen, so that the measuring process is convenient and simple, the size of the eddy current sensor is small, and the space of electronic equipment can be saved.

Under the condition that one end of the first part, which is far away from the bent part, and one end of the second part, which is far away from the bent part, are close to each other, applying a first bias voltage in the opposite direction to the first eddy current sensor and the second eddy current sensor; under the condition that one end of the first part, which is far away from the bent part, and one end of the second part, which is far away from the bent part, are far away from each other, the same-direction first bias voltage is applied to the first eddy current sensor and the second eddy current sensor.
Wherein, first eddy current sensor and second eddy current sensor set up along the kink symmetry.
In the embodiment of the present application, a bias voltage may be superimposed on an excitation voltage generated by an eddy current sensor to generate an attraction force or a repulsion force, the eddy current excitation voltage with auxiliary function is applied to two eddy current sensors to excite a same-direction bias magnetic field when detecting that one end of the first portion 11 departing from the bent portion 13 and one end of the second portion 12 departing from the bent portion 13 are away from each other, that is, when a folding angle is increased, that is, in a process of unfolding the folding screen of the electronic device, and similarly, when detecting that one end of the first portion 11 departing from the bent portion 13 and one end of the second portion 12 departing from the bent portion 13 are close to each other, that is, when the folding angle is decreased, that is, in a process of folding the folding screen of the electronic device, opposite-direction bias voltages are applied to the two eddy current sensors to excite a reverse first bias magnetic field, so as to generate an attraction force, and when the folding screen is completely folded, the suction force is continuously generated, and the function of rebounding resistance is achieved. The opening of the auxiliary function can reduce the force applied by a user in unfolding and folding the folding screen electronic equipment, and better assist the user in operating and using the folding screen electronic equipment, such as a folding screen mobile phone.
The magnitude of the first bias voltage applied to the two eddy current sensors may be the same or different, and specifically, may be determined according to the position of the eddy current sensor, the size of the coil, and the like.
In one possible embodiment of the present application, the method for detecting a folding angle of an electronic device may further include the following steps.

Wherein the second bias voltage is greater than the first bias voltage.
In the embodiment of the application, the second bias voltage larger than the first bias voltage is applied to the first eddy current sensor and the second eddy current sensor, so that the force applied to the electronic equipment by a user when the electronic equipment is used for folding and unfolding the screen can be further reduced, namely, an initial force is given to the electronic equipment as long as the user unfolds or folds the foldable screen, after the system detects that the foldable screen reaches a certain angle, the user does not need to apply an acting force any more, the unfolding or folding of the foldable screen can be automatically realized through the repulsive force or the attractive force of the first eddy current sensor and the second eddy current sensor, and the user experience is further improved.
