Referring to fig. 1 to 4, an electronic device 100 according to an embodiment of the present application includes a case assembly 10 and a flexible screen 20. The housing assembly 10 forms a receiving cavity 101 and the flexible screen 20 is connected to the housing assembly 10. The electronic device 100 may also include a circuit board (not shown) and a battery (not shown), both of which may be disposed within the receiving cavity 101 of the housing assembly 10. The circuit board may integrate the processor, power management module, memory unit, baseband chip, etc. of the electronic device 100. The flexible screen 20 is communicatively coupled to the processor and the battery is capable of powering the flexible screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may further include a camera module (not shown), where the camera module is communicatively connected to the circuit board, and the battery can supply power to the camera module. It is understood that the electronic device 100 according to the embodiment of the present application includes, but is not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic devices 100.

The housing assembly 10 includes a first housing 12 and a second housing 14 movably coupled, the second housing 14 and the first housing 12 being capable of relative movement in a first direction. The flexible screen 20 is connected to the first housing 12 and the second housing 14. As the first housing 12 and the second housing 14 move relative to each other in the first direction, the flexible screen 20 is extended from within the housing assembly 10 or retracted within the housing assembly 10 in the first direction for the purpose of adjusting the extended length of the flexible screen 20.

In some embodiments, the second housing 14 and the first housing 12 are slidably connected. In other words, the second housing 14 is capable of sliding relative to the first housing 12. For example, one of the first and

second housings

12 and 14 may be provided with a slide rail along which the other can slide to enable the first and

second housings

12 and 14 to move telescopically with each other. In other embodiments, the second housing 14 and the first housing 12 may be movably coupled by other structures that are capable of telescoping movement in the first direction. For example, a plurality of connecting rods are connected between the first casing 12 and the second casing 14, and two ends of each connecting rod are respectively connected with the first casing 12 and the second casing 14 and maintain that the first casing 12 and the second casing 14 can only move relatively along the first direction, so that the movable connection between the first casing 12 and the second casing 14 along the first direction is realized. The manner of the movable connection between the first housing 12 and the second housing 14 is not limited herein.

The second housing 14 is movable in a first direction relative to the first housing 12 to a stowed position and a deployed position. As shown in fig. 1 and 2, the electronic device 100 has a relatively small external dimension when the second housing 14 is in the folded position, and is convenient to carry. As shown in fig. 3 and 4, when the second housing 14 is in the unfolded position, the electronic device 100 can obtain a relatively large display area, so as to obtain a visual experience of a large screen display, so as to improve the use experience of the electronic device 100. Thus, with this arrangement, the area of the display screen of the flexible screen 20 (hereinafter referred to as the display interface 20 a) can be adjusted by relative sliding expansion and contraction of the first housing 12 and the second housing 14. In some embodiments, when the second housing 14 is in the folded position, the display interface 20a exposed outside the housing assembly 10 is generally rectangular, and may have a size of 4.5 inches to 7 inches, which is comparable to the size of the display screen of a typical smart phone, so that the electronic device 100 is convenient to carry and use.

It should be noted that, as a structural member of the electronic device 100 for displaying or touching, the flexible screen 20 has a display area, where the display area corresponds to an area of the flexible screen 20 corresponding to a maximum display screen, or when the first housing 12 and the second housing 14 are in the extended position during the relative sliding and stretching process, that is, when the display interface 20a is at a maximum, the display interface 20a is the same as the display area. Since the first casing 12 and the second casing 14 are housed inside without being exposed during sliding expansion and contraction of the first casing 12 and the second casing 14 with respect to each other, the display area of the flexible screen 20 is not displayed. The display interface 20a refers to a portion of the display area exposed to the first housing 12 and the second housing 14. When the display interface 20a is turned on or the screen is displayed, the content displayed on the display interface 20a can be observed from the outside of the electronic device 100.

It is to be understood that in the embodiments described hereinafter, the collapsed position, the extended position, and the like refer to the relative positions of the second housing 14 and the first housing 12. For simplicity, similar expressions of "the second housing 14 is in the collapsed position" or "in the collapsed position" refer to the second housing 14 being in the collapsed position relative to the first housing 12, and similar expressions of "the second housing 14 is in the deployed position" or "in the deployed position" refer to the second housing 14 being in the deployed position relative to the first housing 12.

As shown in connection with fig. 2 and 4, the flexible screen 20 may include a fixed end 202 and a free end 204 disposed opposite to each other, where the fixed end 202 is disposed on the second housing 14 and is fixed relative to the position of the second housing 14, and the free end 204 is movably disposed in the receiving cavity 101 of the housing assembly 10. Specifically, as shown in fig. 2, when the second housing 14 is in the folded position, the free end 204 of the flexible screen 20 is received in the case assembly 10, so that a portion of the structure of the flexible screen 20 is hidden in the case assembly 10, and a portion of the flexible screen 20 hidden in the case assembly 10 may not be used for display. As shown in fig. 4, the structure of the portion of flexible screen 20 proximate free end 204 gradually expands from housing assembly 10 as second housing 14 moves relative to first housing 12 toward the expanded position. In other embodiments, the fixed end 202 is disposed on the first housing 12 and is fixed relative to the position of the first housing 12, and the free end 204 moves within the receiving cavity 101 of the housing assembly 10 as the second housing 14 moves relative to the first housing 12, and allows a portion of the flexible screen 20 to be deployed or retracted into the receiving cavity 101 of the housing assembly 10.

It will be appreciated that in the embodiments of the present application, the positions of the two objects are relatively fixed, that is, the two objects cannot generate relative motion under normal conditions, and the two objects with relatively fixed positions may be directly connected physically, or may be indirectly connected through an intermediate structure. Taking the fixing end 202 and the second housing 14 as examples, the positions of the fixing end 202 and the second housing 14 are relatively fixed, which may be that the fixing end 202 is in direct contact with the second housing 14, for example, a threaded fastener or a clamping manner is adopted to directly fix the fixing end 202 and the second housing 14, or that the fixing end 202 is indirectly fixed with the second housing 14 through an adhesive layer, an intermediate connecting plate and other structures.

The second housing 14 may also include a rear cover 121, the rear cover 121 covering the free end 204 of the flexible screen 20 in the stowed position.

Further, the rear cover 121 may be provided with a light-transmitting area, and a portion of the flexible screen 20 accommodated in the housing assembly 10 may also be used for displaying when in the folded position, so that a user can view information displayed by the flexible screen 20 from the light-transmitting area, and further expand the use scenario of the electronic device 100. For example, in this embodiment, the electronic device 100 can realize functions such as self-timer, video call, and the like by using a rear camera module without providing a front camera. The light-transmitting region may be made of transparent glass or may be formed by an opening of the rear cover 121.

With continued reference to fig. 2 and 4, the electronic device 100 is provided with a traction member 30, where the traction member 30 is disposed at an end of the first housing 12 away from the second housing 14, and the traction member 30 can draw the flexible screen 20 to deform during the process of switching the second housing 14 from the folded position to the unfolded position relative to the first housing 12, so that a portion of the flexible screen 20 unfolded from the second housing 14 is flat. When the second housing 14 is in the folded position, the free end 204 of the flexible screen 20 bypasses the traction member 30, and the traction member 30 can limit the bending radius of the flexible screen 20 within a proper range so as to avoid damage to the flexible screen 20 caused by too small bending radius. Of course, the traction member 30 can also avoid the excessive thickness of the electronic device 100 caused by the excessive bending radius of the flexible screen 20.

In some embodiments, the traction element 30 may be a rotating shaft structure with teeth, and the flexible screen 20 is coupled to the traction element 30 by engagement or the like. When the second housing 14 slides relative to the first housing 12, the traction member 30 moves the portion of the flexible screen 20 engaged with the traction member 30 and is extended from the housing assembly 10 or retracted into the housing assembly 10.

In other embodiments, the traction members 30 are circular shafts without accompanying teeth. During the switching of the second housing 14 from the folded position to the unfolded position, the portion of the flexible screen 20 attached to the traction member 30 is spread by the traction member 30 so that more of the flexible screen 20 is exposed to the outside of the housing assembly 10 and kept flat. In this embodiment, the traction member 30 may be rotatably disposed on the second housing 14, and the traction member 30 may rotate along with the movement of the flexible screen 20 during the gradual deployment of the flexible screen 20, so as to reduce the resistance of the flexible screen 20 during the deployment process and reduce the abrasion of the contact portion between the traction member 30 and the flexible screen 20.

In some embodiments, the traction member 30 may also be fixed to the first housing 12, the traction member 30 having a smooth surface. The retractor 30 is in slidable contact with the flexible screen 20 through its smooth surface during deployment of the flexible screen 20. In other words, in such embodiments, the pulling member 30 may be integrally formed with the first housing 12 or welded, and the pulling member 30 may be considered as a portion of the first housing 12, with the free end 204 of the flexible screen 20 bypassing the end of the first housing 12 remote from the second housing 14 and extending into the housing assembly 10.

As shown in connection with fig. 5, in some embodiments, in a first direction, the first housing 12 has a first side wall 12a facing the side of the second housing 14, and the second housing 14 has a second side wall 14a facing the side of the first housing 12. Understandably, as the second housing 14 moves toward the collapsed position relative to the first housing 12, the first side wall 12a and the second side wall 14a approach each other until the second housing 14 moves to the collapsed position. In some embodiments, when the second housing 14 is in the folded position, the first side wall 12a contacts the second side wall 14a, so that the first housing 12 and the second housing 14 are aligned by stitching, and the overall appearance texture of the electronic device 100 is maintained. It will be appreciated that in some embodiments, the first side wall 12a and the second side wall 14a may also have a gap when the second housing 14 is in the folded position, and the width of the gap is less than or equal to 1mm. The width of the gap is controlled within this range, and the gap between the first side wall 12a and the second side wall 14a is negligibly small, so that even if the second housing 14 is in the folded position, the gap exists between the first side wall 12a and the second side wall 14a, but the influence on the overall appearance of the electronic apparatus 100 is small.

The inventors have found that a user may inadvertently place a finger between the first side wall 12a and the second side wall 14a while the second housing 14 is moved relative to the first housing 12 to the stowed position, with the finger risking pinching the first side wall 12a and the second side wall 14 a. In this regard, the inventors have long studied and made technical efforts, and have found that this technical problem can be solved by improving the electronic apparatus 100.

For convenience of description, the area of the electronic device 100 that is easily affected by the finger during the process of folding the flexible screen 20 is referred to as a "detection area 10a", and it is understood that the detection area 10a is an area where the finger is not desired during the process of folding the flexible screen 20, that is, an area where finger pinching easily occurs.

Specifically, in the embodiment of the present application, when the second housing 14 moves to a preset position relative to the first housing 12, the detection area 10a is formed by the area between the corresponding first sidewall 12a and the second sidewall 14a of the housing assembly 10. It should be noted that the preset position may be any intermediate position of the second housing 14 during the movement between the extended position and the retracted position relative to the first housing 12, specifically, the preset position may be a position where the second housing 14 is located at the moment of being separated from the extended position, and at this time, the distance between the preset position and the extended position is close to 0, and the preset position may be considered to be the same as the extended position without any error. Of course, in some embodiments, the preset position is the same as the deployed position, and the preset position and the deployed position are distinguished only for the convenience of understanding the detection region 10a.

As shown in fig. 4 and 5, the electronic device 100 includes a driving mechanism 40, an electrical grounding member 50, a conductive metal member 60, a voltage acquisition module 70, and a controller 80.

The driving mechanism 40 is disposed in the accommodating cavity 101 of the housing assembly 10, and is used for driving the first housing 12 and the second housing 14 to relatively move along the first direction, so that the second housing 14 drives the flexible screen 20 to be unfolded from the housing assembly 10 or to be retracted into the housing assembly 10.

In some embodiments, the first housing 12 and the second housing 14 are connected to the driving mechanism 40 and move relatively under the driving of the driving mechanism 40. Specifically, the driving mechanism 40 has a fixed portion and a movable portion, and the movable portion is movable relative to the fixed portion when the driving mechanism 40 is operated. The fixed portion is connected with the first shell 12, the movable portion is connected with the second shell 14, and the movable portion is used for driving the second shell 14 to move relative to the first shell 12.

The driving mechanism 40 may be a belt transmission structure or a gear transmission structure, or may be a telescopic transmission structure such as a cylinder. The structure of the driving mechanism 40 is not limited herein, as long as the driving mechanism 40 can drive the first housing 12 and the second housing 14 to relatively move to adjust the deployment length of the flexible screen 20 in the first direction.

The electrical grounding member 50 is connected to the housing assembly 10, and the electrical grounding member 50 is a structural member for electrical grounding, for example, as shown in fig. 6, in the electronic device 100, the electrical grounding member 50 is electrically connected to a GND line (Ground) in a circuit of the electronic device 100.

The conductive metal member 60 is connected with the case assembly 10. In some embodiments, the conductive metal member 60 and the electrical grounding member 50 are both metal conductive sheets (e.g., copper sheets or aluminum sheets), and are formed on the shell assembly 10 by electroplating or coating, or may be connected to the shell assembly 10 by injection molding or clamping, for example.

It should be noted that, when the second housing 14 is located at the preset position, the electrical grounding member 50 and the conductive metal member 60 are exposed at the portion of the housing assembly 10 corresponding to the detection area 10a, so that when the finger of the user contacts the electrical grounding member 50 and the conductive metal member 60 at the same time, it indicates that the finger of the user is located at the detection area 10a, so that the requirement of detecting whether the finger is present in the detection area 10a can be satisfied by this arrangement.

Specifically, as shown in connection with fig. 6, the conductive metal member 60 is electrically connected to a power source VCC, which may be provided by a battery of the electronic device 100, through a resistive element. The conductive metal member 60 and the electrical grounding member 50 are disposed at intervals, and if no external object is used to electrically connect the conductive metal member 60 and the electrical grounding member 50, the voltage on the conductive metal member 60 will be the voltage of the power source VCC. When the user's finger contacts both the electrical ground 50 and the conductive metal 60, the conductive metal 60 connects the resistive element in series with the user's finger. Through this structure setting, when the finger is located in the detection area 10a, the finger contacts with the electrical grounding member 50 and the conductive metal member 60 simultaneously, and the conductive characteristic of the user's finger will have a voltage dividing effect on the voltage on the conductive metal member 60 with respect to the resistance, and then it can be known whether the user's finger is placed in the detection area 10a according to the voltage value of the conductive metal member 60.

In this embodiment, the voltage acquisition module 70 is electrically connected to the conductive metal member 60 and is used for acquiring a voltage value at the conductive metal member 60.

The conductive metal member 60 is connected to the first housing 12 and is fixed relative to the first sidewall 12 a. The voltage collecting module 70 is electrically connected to the conductive metal piece 60, and the voltage collecting module 70 may be an ADC (Analog-to-digital converter) module to detect a voltage value of the conductive metal piece 60, and since the finger is in the detection area 10a, the voltage applied to the conductive metal piece 60 by the power VCC has a voltage drop due to the conductive characteristic of the finger, and the voltage drop is the voltage value of the conductive metal piece 60 collected by the voltage collecting module 70.

The controller 80 is electrically connected to the voltage acquisition module 70. Specifically, the controller 80 is configured to control the working state of the driving mechanism 40 according to the voltage value, and when the voltage value exceeds the preset range, the controller 80 controls the driving mechanism 40 to drive the second housing 14 to move towards the deployed position relative to the first housing 12 or controls the driving mechanism 40 to stop driving the second housing 14 to move relative to the first housing 12, so as to effectively reduce the probability of pinching the fingers of the user.

It should be noted that the preset range may be set according to the voltage value detected by the voltage acquisition module 70 when the finger is present in the detection area 10a. For example, when the finger of the user is placed in the detection area 10a, the voltage value of the voltage acquisition module 70 is a first value, and when the finger of the user is not placed in the detection area 10a, the voltage value of the voltage acquisition module 70 is a second value, because the finger has a conductive property and is equivalent to a resistor, a voltage division effect can be achieved, at this time, the first value and the second value have a difference, and a preset range can be reasonably configured according to the first value and the second value, so that whether the finger of the user is placed in the detection area 10a can be judged by the voltage value detected by the voltage acquisition module 70. Assuming that the first value detected by the voltage acquisition module 70 is the voltage value of the power VCC when the finger of the user is placed in the detection area 10a, the conductive characteristic of the finger connects the conductive metal member 60 with the electrical grounding member 50 when the finger of the user is placed in the detection area 10a, and at this time, the finger corresponds to a resistor, so that voltage division can be achieved, and thus the second value detected by the voltage acquisition module 70 will be smaller than the voltage value of the power VCC. Thus, the preset range may be any value or any range of values between the first value and the second value.

In this embodiment, the electrical characteristics of the finger of the user are utilized, and when the finger contacts the electrical grounding member 50 and the conductive metal member 60 at the same time, the finger corresponds to a resistor in the circuit, and as a part of the circuit, the finger will generate a voltage dividing effect in the circuit, so that the voltage acquisition module 70 detects the voltage at the conductive metal member 60, and it can be determined whether the finger is placed in the detection area 10 a.

It should be noted that, since the electrical resistivity of the finger of the user is different from that of the metal, if the metal member of the electronic device 100 itself makes the conductive metal member 60 electrically connected to the electrical grounding member 50, the voltage value detected by the voltage collecting module 70 is different, and in this case, the voltage value detected by the voltage collecting module 70 does not exceed the preset range, so that when detecting whether the finger is placed in the detection area 10a, erroneous judgment is not generated due to the metal member. Accordingly, the material of the case assembly 10 of the electronic device 100 can be appropriately selected from a metal structure, and the material of the case assembly 10 can be widely selected.

The voltage acquisition module 70 and the controller 80 may be integrated on a circuit board of the electronic device 100, or the voltage acquisition module 70 and the controller 80 may be separately provided, which is not limited herein.

In some embodiments, as shown in fig. 7, the displacement of the second housing 14 from the deployed position to the preset position is the first displacement D1, and the displacement of the second housing 14 from the preset position to the folded position is the second displacement D2. The first displacement D1 is greater than the second displacement D2, so that the width of the detection area 10a in the first direction (i.e., the second displacement D2) is preferably proportional to the overall movement stroke of the second housing 14 relative to the first housing 12. Specifically, since the voltage acquisition module 70 detects the voltage value at the conductive metal member 60 during the driving mechanism 40 drives the second housing 14 to move from the preset position to the folded position relative to the first housing 12, that is, the voltage acquisition module 70 detects during the second displacement D2 of the second housing 14, the detection during the first displacement D1 of the second housing 14 is not required, so as to reduce the power consumption.

In some embodiments, the width of the detection region 10a in the first direction ranges from 0.5cm to 2.0cm, such as 0.5cm, 0.7cm, 0.9cm, 1.2cm, 1.5cm, 1.7cm, 1.9cm, or 2.0cm. In this embodiment, the value range of the second displacement D2 is controlled to be 1.2cm to 2.0cm, so that the detection area 10a can be ensured to have a sufficient detection width in the first direction, so that the voltage acquisition module 70 can not detect the finger after the finger is injured, and meanwhile, the detection width of the detection area 10a in the first direction can be prevented from being too large, which causes unnecessary energy consumption waste.

In some embodiments, the front projection of the conductive metal piece 60 on the plane of the display interface 20a and the front projection of the detection area 10a on the plane of the display interface 20a are at least partially overlapped, so that the conductive metal piece 60 is disposed as close to the detection area 10a as possible, so as to improve the accuracy of the detection of the SAR value by the voltage acquisition module 70 through the conductive metal piece 60 in the detection area 10 a.

As shown in connection with fig. 4 and 5, in some embodiments, the housing assembly 10 includes a third housing 16, and at least a portion of a back surface 161 of the third housing 16 (a surface facing away from the interior of the electronic device 100) is exposed between the first side wall 12a and the second side wall 14a when the second housing 14 is in the deployed position, so that the internal structure of the electronic device 100 is prevented from being exposed between the first side wall 12a and the second side wall 14a by the third housing 16, and specifically, the third housing 16 may provide an exterior surface of the electronic device 100 when the second housing 14 is in the deployed position to maintain exogenous integrity of the electronic device 100. It is understood that when the second housing 14 is in the folded position, the third housing 16 is hidden from the first housing 12 and the second housing 14, and at this time, the first housing 12 and the second housing 14 form the exterior surface of the electronic device 100.

The third housing 16 may be integrally formed with the second housing 14, or may be connected to the second housing 14 by glue or screws. In other embodiments, both the first housing 12 and the second housing 14 are slidably coupled to the third housing 16 such that the third housing 16 may be utilized to provide stable support for sliding movement between the first housing 12 and the second housing 14.

It should be noted that, there are various possible positions of the electrical grounding member 50 and the conductive metal member 60 corresponding to the detection area 10 a. Specifically, since the detection area 10a is an area of the housing assembly 10 corresponding to the first sidewall 12a and the second sidewall 14a, and the electrical grounding member 50 and the conductive metal member 60 are exposed from a portion of the housing assembly 10 corresponding to the detection area 10a, the location of the electrical grounding member 50 and the conductive metal member 60 in the housing assembly 10 may be the first sidewall 12a, the second sidewall 14a or a portion of the housing assembly 10 between the first sidewall 12a and the second sidewall 14 a.

In some embodiments, at least one of the back surface 161 and the second side wall 14a of the third housing is provided with an electrical ground 50, and the conductive metal member 60 is disposed on the first side wall 12a. For example, as shown in fig. 5, the back surface 161 of the third housing 16 is provided with an electrical grounding member 50, and the conductive metal member 60 is disposed on the first sidewall 12a.

In other embodiments, at least one of the back surface 161 and the first side wall 12a of the third housing is provided with an electrical grounding member 50, and the conductive metal member 60 is disposed on the second side wall 14a. For example, as shown in fig. 6, the back surface 161 and the first side wall 12a of the third housing 16 are both provided with the electrical grounding member 50, and the conductive metal member 60 is disposed on the second side wall 14a, so that even if one electrical grounding member 50 fails, the other electrical grounding members 50 can still meet the contact requirement with fingers, thereby improving the reliability of the electronic device 100 for preventing the fingers from being pinched.

It will be appreciated that the location of the conductive metal member 60 on the housing assembly 10 may be interchanged with the location of the electrical grounding member 50 on the housing assembly 10, because even if the locations of the conductive metal member 60 and the electrical grounding member 50 are interchanged, the conductive characteristic of the finger can have the effect of voltage dividing resistance so long as the finger can contact the conductive metal member 60 and the electrical grounding member 50 at the detection area 10a at the same time, so that there is a voltage change in the position where the finger contacts the detection area 10a before and after the finger contacts the detection area 60.

In other embodiments, as shown in connection with fig. 7-10, in embodiments where the housing assembly 10 includes the third housing 16, the conductive metal member 60 may be disposed on the back surface 161 of the third housing, where at least one of the first sidewall 12a and the second sidewall 14a may be provided with an electrical ground member 50. For example, as shown in fig. 7, the conductive metal member 60 is disposed on the back surface 161 of the third housing, and the first sidewall 12a is provided with the electrical grounding member 50. As another example, as shown in fig. 8 and 9, the conductive metal member 60 is disposed on the back surface 161 of the third housing, and the second sidewall 14a is provided with the electrical grounding member 50. Alternatively, as shown in fig. 10, the conductive metal member 60 is disposed on the back surface 161 of the third housing, and the first side wall 12a and the second side wall 14a are both provided with the electrical grounding member 50.

It should be noted that, the electrical grounding element 50 and the conductive metal element 60 may not be disposed in the third housing, for example, the electrical grounding element 50 and the conductive metal element 60 may be disposed on the first side wall 12a and the second side wall 14a, respectively, so that when the finger is placed in the detection area 10a, the second side wall 14a and the first side wall 12a are close to each other and finally contact the finger during the movement of the second housing 14 relative to the first housing 12 toward the folded position, and at this time, the finger contacts the electrical grounding element 50 and the conductive metal element 60 at the same time, so as to adapt to the detection requirement of whether the finger exists in the detection area 10 a. Specifically, in this embodiment, one of the electrical grounding member 50 and the conductive metal member 60 is disposed on the first sidewall 12a, and the other is disposed on the second sidewall 14a.

The positions of the electrical grounding member 50 and the conductive metal member 60 in the housing assembly 10 will not be described herein, as long as the positions of the electrical grounding member and the conductive metal member corresponding to the detection area 10a satisfy the requirements for contact detection of the finger.

In the above embodiments, the structures of the electrical grounding member 50, the conductive metal member 60, the voltage acquisition module 70, the controller 80, and the like of the electronic device 100 of the present application can effectively prevent the first housing 12 and the second housing 14 that move relative to each other from damaging the fingers of the user. The flexible screen 20 is not necessary for the electronic device 100 to be tamper proof, i.e., in some embodiments of the electronic device 100, the flexible screen 20 may be omitted.

Based on the electronic device 100 described above, another embodiment of the present application provides a method for preventing fingers from being pinched during the use of the electronic device 100, which is used for controlling the electronic device 100 described above.

Specifically, as shown in connection with fig. 11, the anti-pinch method includes the steps of:

step S102, the first control operation information is received, and the driving mechanism 40 is controlled to drive the second housing 14 to move towards the retracted position relative to the first housing 12 according to the first control operation information.

In the embodiment where the electronic device 100 includes the flexible screen 20, the first operation control information is a control instruction related to controlling the folding operation of the flexible screen 20. For example, the first control operation information may be input to the electronic device 100 by a user clicking, sliding, dragging, or the like on the operation interface of the flexible screen 20, or may be input by operating a key of the electronic device 100. In some application scenarios, when the user performs a sliding operation on the flexible screen 20 by using two fingers in directions approaching each other, the driving mechanism 40 will drive the second housing 14 to move toward the folded position relative to the first housing 12, so as to fold the flexible screen 20. In embodiments where the electronic device 100 does not include the flexible screen 20, the first operational control information may be control instructions related to movement of the second housing 14 relative to the first housing 12 toward the stowed position.

In step S104, when the driving mechanism 50 drives the second housing 14 to move to the preset position relative to the first housing 12, the voltage acquisition module 70 of the electronic device 100 acquires the voltage value at the conductive metal piece 60.

When the finger of the user is placed in the detection area 10a, the voltage value of the voltage acquisition module 70 is a first value, and when the finger of the user is not placed in the detection area 10a, the voltage value of the voltage acquisition module 70 is a second value, and the finger has a conductive characteristic and is equivalent to a resistor, so that a voltage division effect can be achieved.

In step S106, if the voltage value exceeds the preset range, the control driving mechanism 40 drives the second housing 14 to move toward the deployed position relative to the first housing 12 or the control driving mechanism 40 stops driving the second housing 14 to move relative to the first housing 12.

When the detection area 10a has a finger, the voltage value exceeds the preset range, and the driving mechanism 40 will not continue to drive the second housing 14 to move towards the folded position relative to the first housing 12, so as to effectively reduce the probability of the finger of the user being pinched, and at the same time, avoid the driving mechanism 40 from being damaged due to a larger reaction force.

As shown in fig. 12, in some embodiments, after the voltage value is obtained, specifically, after step S104, by determining whether the voltage value exceeds the preset range, it can be clearly detected whether the finger is present in the area 10a, so that the electronic device 100 can perform the subsequent operation.

When the voltage value exceeds the preset range, step S106 is performed, in which the control driving mechanism 40 drives the second housing 14 to move toward the deployed position relative to the first housing 12 or the control driving mechanism 40 stops driving the second housing 14 to move relative to the first housing 12.

When the voltage value is not beyond the preset range, step S108 is performed, that is, when no other control operation information for controlling the working state of the driving mechanism 40 is received, the driving mechanism 40 is controlled to drive the second housing 14 to move from the preset position to the folded position relative to the first housing 12 according to the first control operation information. Thus, the second housing 14 is returned to the retracted position, at which time the electronic device 100 has a relatively small overall size and is portable.

In some embodiments, the anti-pinch method further comprises the step of:

the second control operation information is received, and the driving mechanism 40 is controlled to drive the second housing 14 to move toward the deployed position relative to the first housing 12 according to the second control operation information.

In the embodiment in which the electronic device 100 includes the flexible screen 20, the second operation control information is a control instruction related to controlling the unfolding operation of the flexible screen 20. For example, the second control operation information may be input to the electronic device 100 by a user clicking, sliding, dragging, or the like on the operation interface of the flexible screen 20, or may be input by operating a key of the electronic device 100. In some applications, when a user performs a sliding operation on the flexible screen 20 by two fingers in directions away from each other, the driving mechanism 40 will drive the second housing 14 to move toward the deployed position relative to the first housing 12 to deploy the flexible screen 20. In embodiments where the electronic device 100 does not include the flexible screen 20, the first operational control information may be control instructions related to movement of the second housing 14 relative to the first housing 12 toward the stowed position.

It should be noted that this step may be performed during any process of using the electronic device 100 as a control of the unfolding operation of the flexible screen 20. For example, the step of controlling the driving mechanism 40 to drive the second housing 14 to move toward the deployed position with respect to the first housing 12 according to the second control operation information may be after the step of controlling the driving mechanism 40 to stop driving the second housing 14 to move with respect to the first housing 12.

In some embodiments in which the electronic device 100 includes the flexible screen 20, the flexible screen 20 may be utilized to display a prompt to alert the user of the abnormality of the electronic device 100 during the collapsing process. Specifically, the anti-pinch method further comprises the steps of:

if the voltage value exceeds the preset range, the flexible screen 20 is controlled to display a reminding interface so as to remind the user of the abnormality of the detection area 10 a.

The means for prompting the user to detect the presence of an abnormality in the area 10a may be a graphic or an animation. For example, when the detection area 10a is abnormal in clamping the hand, the flexible screen 20 displays an image or animation of the hand being clamped or injured to vividly alert the user, and the alert mode is also interesting. In some embodiments, the method can also prompt the user to detect the abnormality of the area 10a by means of flashing text or a display screen.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
