Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to electronic equipment, a control method and a computer-readable storage medium. Background Art

[0002] In the current intelligent information age, users use electronic devices more and more frequently, and the usage scenarios are becoming more and more diverse. Currently, the screen size of most portable intelligent electronic devices is less than 7 inches. Compared with tablets and laptops, the screen display area is limited, and the user operation experience is restricted.

[0003] The emergence of flexible screens solves this problem very well. By bending or curling the flexible screen, the large screen can be stored in a small body, making it easier for users to carry. At the same time, the small screen can be used as a normal mobile phone. When switched to a large screen, news reading and social chatting can be realized at the same time. At the same time, it can also improve the user's gaming experience, greatly enriching the user's usage scenarios.

[0004] However, in order to meet the needs of flexible screen expansion and contraction, the shell component of the electronic device needs to be configured into at least two parts that can move relative to each other. In this way, when the flexible screen is folded, the shell component of the electronic device is easy to pinch the user's fingers or foreign objects, resulting in a poor user experience of the electronic device. When using sensors for anti-pinch detection, it is easy to be affected by temperature and make misjudgments, resulting in the electronic device's shell component not closing when it should, and the problem of poor user experience of the electronic device still exists. Summary of the invention

[0005] The present application provides an electronic device, a control method and a computer-readable storage medium to solve the technical problems that the housing of the electronic device is easy to pinch fingers and is easily affected by temperature and causes misjudgment, resulting in a poor user experience.

[0006] On the one hand, an embodiment of the present application provides an electronic device, including:

[0007] A shell assembly, comprising a first shell and a second shell that are movably connected;

[0008] a driving mechanism, used for driving the second shell to move relative to the first shell along a first direction to an extended position or a retracted position, wherein a detection zone is formed on the back of the shell assembly, and when the second shell moves from the extended position to the retracted position, a width of the detection zone in the first direction gradually decreases;

[0009] A shielding member connected to the shell assembly and forming a shielding area outside the detection area, wherein the shielding member is electrically grounded;

[0010] A first radiator connected to the shell component and corresponding to the detection area;

[0011] a second radiator connected to the shell assembly and corresponding to the shielding area;

[0012] a capacitance sensor electrically connected to the first radiator and the second radiator, the capacitance sensor being configured to obtain a first capacitance value through the first radiator and a second capacitance value through the second radiator; and

[0013] A controller is electrically connected to the capacitive sensor, and is used to perform temperature-impact shielding processing on the first capacitance value according to the second capacitance value to obtain a third capacitance value, and is used to control the driving mechanism to drive the second shell to move relative to the first shell. When the second shell moves toward the folded position, if the third capacitance value exceeds a preset range, the controller controls the driving mechanism to drive the second shell to move toward the expanded position or controls the driving mechanism to stop driving the second shell to move.

[0014] On the other hand, an embodiment of the present application provides a control method for controlling an electronic device, wherein the electronic device includes a shell assembly and a driving mechanism provided on the shell assembly, wherein the shell assembly includes a first shell and a second shell that are movably connected, wherein the second shell can be driven by the driving mechanism to move relative to the first shell along a first direction to an extended position or a retracted position, wherein a detection area is formed on the back of the shell assembly, and when the second shell moves from the extended position to the retracted position, the width of the detection area in the first direction gradually decreases, and the shell assembly is connected to a shielding member, wherein the shielding member forms a shielding area outside the detection area;

[0015] The control method comprises the following steps:

[0016] receiving control operation information, and controlling the driving mechanism to drive the second housing to move toward the retracted position according to the control operation information;

[0017] The capacitive sensor of the electronic device obtains a first capacitance value in the detection area through a first radiator; the capacitive sensor obtains a second capacitance value in the shielding area through a second radiator;

[0018] Performing temperature impact shielding processing on the first capacitance value according to the second capacitance value to obtain a third capacitance value;

[0019] If the third capacitance value exceeds a preset range, the driving mechanism is controlled to drive the second shell to move toward the unfolded position, or the driving mechanism is controlled to stop driving the second shell to move.

[0020] On the other hand, an embodiment of the present application provides a computer-readable storage medium having computer-readable instructions stored thereon, and the computer-readable instructions implement the steps of the above-mentioned control method when executed by a processor.

[0021] In the electronic device, control method and computer-readable storage medium of the present application, a channel for obtaining a second capacitance value is constructed for the capacitive sensor by using the shielding area provided by the second radiator in the shielding part. Since the second radiator will not be affected by the detection area in the shielding area, the second capacitance value will not be affected by whether a finger or foreign object is placed outside the shielding area, and can reflect the influence of temperature on the capacitance value. In this way, the first capacitance value is shielded from the influence of temperature according to the second capacitance value, and the influence of temperature on the capacitance value is excluded from the first capacitance value. The third capacitance value obtained can accurately characterize that the capacitance change in the detection area is caused by a finger or foreign object placed in the detection area, rather than by temperature. This reduces the probability of misjudging the situation where a finger or foreign object is not placed in the detection area due to the influence of temperature as a finger or foreign object being placed in the detection area, and improves the accuracy of the controller's control over the working state of the drive mechanism.

[0046] See also Figures 1 to 4 As shown, an electronic device 100 provided in an embodiment of the present application includes a shell assembly 10 and a flexible screen 20. The shell assembly 10 forms a receiving cavity 101, and the flexible screen 20 is connected to the shell assembly 10. The electronic device 100 may also include a circuit board (not shown) and a battery (not shown), and both the circuit board and the battery may be arranged in the receiving cavity 101 of the shell assembly 10. The circuit board may integrate a processor, a power management module, a storage unit, and a baseband chip of the electronic device 100. The flexible screen 20 is communicatively connected to the processor, and the battery can power the flexible screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may also include a camera module (not shown), which is communicatively connected to the circuit board, and the battery can power the camera module. It can be understood that the electronic device 100 of the embodiment of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices.

[0047] The shell assembly 10 includes a first shell 12 and a second shell 14 that are movably connected, and the second shell 14 and the first shell 12 can move relative to each other along a first direction. The flexible screen 20 is connected to the first shell 12 and the second shell 14. As the first shell 12 and the second shell 14 move relative to each other along the first direction, the flexible screen 20 is extended from or retracted into the shell assembly 10 along the first direction, so as to adjust the extended length of the flexible screen 20.

[0048] In some embodiments, the second shell 14 is slidably connected to the first shell 12. In other words, the second shell 14 can slide relative to the first shell 12. For example, one of the first shell 12 and the second shell 14 can be provided with a slide rail, and the other can slide along the slide rail so that the first shell 12 and the second shell 14 can telescope relative to each other. In other embodiments, the second shell 14 and the first shell 12 can be movably connected through other structures that can telescope relative to each other in the first direction. For example, a plurality of connecting rods are connected between the first shell 12 and the second shell 14, and the two ends of the connecting rods are respectively connected to the first shell 12 and the second shell 14 and maintain that the first shell 12 and the second shell 14 can only move relative to each other in the first direction, thereby realizing the movable connection between the first shell 12 and the second shell 14 in the first direction. The movable connection method between the first shell 12 and the second shell 14 is not limited here.

[0049] The second housing 14 can move relative to the first housing 12 along the first direction to a folded position or an extended position. Figure 1 and Figure 2 As shown, when the second housing 14 is in the folded position, the electronic device 100 has a relatively small size and is easy to carry. Figure 3 and Figure 4 As shown, when the second shell 14 is in the unfolded position, the electronic device 100 can obtain a relatively large display area, thereby obtaining a visual experience of a large screen display, so as to enhance the user experience of the electronic device 100. Therefore, through this arrangement, the display area of ​​the flexible screen 20 (hereinafter referred to as the display interface 20a) can be adjusted by the relative sliding extension of the first shell 12 and the second shell 14. In some embodiments, when the second shell 14 is in the retracted position, the display interface 20a exposed outside the shell assembly 10 is roughly rectangular, and its size can be 4.5 inches to 7 inches, which is comparable to the size of the display screen of a general smart phone, so that the electronic device 100 is easy to carry and convenient to use.

[0050] It should be noted that the flexible screen 20, as a structural member used by the electronic device 100 for display or touch control, has a display area, which refers to the area corresponding to the maximum display screen of the flexible screen 20, or in other words, when the first shell 12 and the second shell 14 are in the unfolded position during relative sliding and retracting, that is, when the display interface 20a is at its maximum, the display interface 20a is the same as the display area. Since the first shell 12 and the second shell 14 are sliding and retracting relative to each other, part of the display area of ​​the flexible screen 20 is contained inside and not exposed, so that this part will not present a display screen. The display interface 20a refers to the part of the display area exposed to the first shell 12 and the second shell 14. Then, when the display interface 20a is lit or displays a screen, the content displayed on the display interface 20a can be observed from the outside of the electronic device 100.

[0051] It is understood that in the embodiments of the present application, the folded position, the unfolded position and similar expressions all refer to the relative position of the second housing 14 and the first housing 12. To simplify the expression, "the second housing 14 is in the folded position" or "when in the folded position" and similar expressions refer to the second housing 14 being in the folded position relative to the first housing 12, and "the second housing 14 is in the unfolded position" or "when in the unfolded position" and similar expressions refer to the second housing 14 being in the unfolded position relative to the first housing 12.

[0052] Combination Figure 2 and Figure 4 As shown, the flexible screen 20 may include a fixed end 202 and a free end 204 that are relatively arranged, the fixed end 202 is arranged on the second shell 14 and is relatively fixed to the position of the second shell 14, and the free end 204 is movably located in the receiving cavity 101 of the shell assembly 10. Specifically, as Figure 2 As shown, when the second housing 14 is in the folded position, the free end 204 of the flexible screen 20 is accommodated in the shell assembly 10, so that part of the structure of the flexible screen 20 is hidden in the shell assembly 10, and the part of the flexible screen 20 hidden in the shell assembly 10 may not be used for display. Figure 4 As shown, as the second shell 14 moves toward the unfolded position relative to the first shell 12, the structure of the portion of the flexible screen 20 near the free end 204 is gradually unfolded from the shell assembly 10. In other embodiments, the fixed end 202 is disposed on the first shell 12 and is relatively fixed to the position of the first shell 12. As the second shell 14 moves relative to the first shell 12, the free end 204 moves in the receiving cavity 101 of the shell assembly 10, and a portion of the structure of the flexible screen 20 is unfolded or retracted into the receiving cavity 101 of the shell assembly 10.

[0053] It is understandable that in the embodiments of the present application, the positions of the two objects are relatively fixed, which means that the two objects cannot produce relative movement under normal circumstances. The two objects with relatively fixed positions can be physically directly connected, or indirectly connected through an intermediate structure. Taking the fixed end 202 and the second shell 14 as an example, the positions of the fixed end 202 and the second shell 14 are relatively fixed. The fixed end 202 and the second shell 14 can be directly in contact, such as using threaded fasteners or clamping to achieve direct fixation of the fixed end 202 and the second shell 14, or the fixed end 202 can be indirectly fixed to the second shell 14 through structures such as an adhesive layer and an intermediate connecting plate.

[0054] The second housing 14 may further include a back cover 141 , which covers the free end 204 of the flexible screen 20 when in the unfolded position.

[0055] Furthermore, the back cover 141 may be provided with a light-transmitting area, and the portion of the flexible screen 20 housed in the shell assembly 10 in the unfolded position may also be used for display, so that the user can view the information displayed on the flexible screen 20 from the light-transmitting area, thereby expanding the use scenario of the electronic device 100. For example, in this embodiment, the electronic device 100 does not need to be provided with a front camera, and a rear-mounted camera module can be used to achieve functions such as selfies and video calls. The light-transmitting area may be composed of transparent glass, or it may be formed by an opening in the back cover 141. After the second shell 14 moves to the retracted position relative to the first shell 12, at least part of the flexible screen 20 housed in the shell assembly 10 is exposed. The exposed flexible screen 20 can be used for display, so that the electronic device 100 has a relatively large display area to enhance the user experience.

[0056] Continue to see Combination Figure 2 and Figure 4 As shown, the electronic device 100 includes a driving mechanism 30. The driving mechanism 30 is disposed in the receiving cavity 101 of the shell assembly 10 and is used to drive the first shell 12 and the second shell 14 to move relative to each other along a first direction, so that the second shell 14 drives the flexible screen 20 to be extended from the shell assembly 10 or retracted into the shell assembly 10.

[0057] In some embodiments, the first shell 12 and the second shell 14 are connected to the driving mechanism 30 and move relative to each other under the drive of the driving mechanism 30. Specifically, the driving mechanism 30 has a fixed part and a movable part, and when the driving mechanism 30 is working, the movable part can move relative to the fixed part. The fixed part is connected to the first shell 12, and the movable part is connected to the second shell 14, and is used to drive the second shell 14 to move relative to the first shell 12.

[0058] It should be noted that the driving mechanism 30 can be a belt drive structure or a gear drive structure, or it can be a telescopic drive structure such as a cylinder. The structure of the driving mechanism 30 is not limited here, as long as the driving mechanism 30 can drive the first shell 12 and the second shell 14 to move relative to each other to adjust the unfolded length of the flexible screen 20 in the first direction.

[0059] The inventors found that by utilizing the relative movement of the first shell 12 and the second shell 14 to allow the flexible screen 20 to be extended or retracted into the shell assembly 10, the extended length of the flexible screen 20 in the first direction can be adjusted. However, when the first shell 12 and the second shell 14 move toward the retracted position, there is a risk of pinching the user's fingers. Figure 5 and Figure 6 As shown, the area on the back of the shell assembly 10 where there is a risk of pinching fingers during the process of folding the flexible screen 20 of the electronic device 100 is called the "detection area 10a". It can be understood that the detection area 10a is an area where fingers or foreign objects are not desired to be present during the process of folding the flexible screen 20. The back of the shell assembly 10 refers to the surface of the shell assembly 10 exposed on the side of the electronic device 100 that is away from the display interface 20a. It can be understood that since the first shell 12 and the second shell 14 can move relative to each other in the first direction, the surface of the back of the shell assembly 10 exposed to the electronic device 100 will increase or decrease with the relative movement of the first shell 12 and the second shell 14. To be more specific, when the second shell 14 moves from the expanded position to the folded position, the width of the detection area 10a in the first direction gradually decreases.

[0060] In some embodiments, in combination Figure 5 and Figure 6 As shown, in the first direction, the first housing 12 has a first side wall 12a facing the side where the second housing 14 is located, and the second housing 14 has a second side wall 14a facing the side where the first housing 12 is located. It can be understood that when the second housing 14 moves toward the retracted 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 retracted position. In some embodiments, when the second housing 14 is in the retracted 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 and the overall appearance texture of the electronic device 100 is maintained. It can be understood that in some embodiments, when the second shell 14 is in the folded position, there may be a gap between the first side wall 12a and the second side wall 14a, and the width of the gap is less than or equal to 1 mm. By controlling the width of the gap within this range, the seam between the first side wall 12a and the second side wall 14a is small enough to be ignored, so that even if there is a gap between the first side wall 12a and the second side wall 14a when the second shell 14 is in the folded position, the impact on the overall appearance of the electronic device 100 is small.

[0061] In some embodiments, when the electronic device is in a certain state, the first side wall 12a and the second side wall 14a are spaced apart from each other, and a detection area 10a is defined therebetween. The width of the detection area 10a in the first direction is not limited herein. It is understandable that the detection area 10a may be an area where a user may accidentally place a finger between the first side wall 12a and the second side wall 14a when the second shell 14 moves toward the retracted position relative to the first shell 12, and there is a risk of being pinched by the first side wall 12a and the second side wall 14a. In addition, when a foreign object is stuck between the first side wall 12a and the second side wall 14a, the process of the first side wall 12a and the second side wall 14a approaching each other will be subject to greater resistance, and accordingly, the drive mechanism 30 will also be subject to a greater reaction force. In this case, the drive mechanism 30 is easily damaged, causing the overall performance of the electronic device 100 to decline, or even causing the electronic device 100 to be scrapped.

[0062] Specifically in the embodiments of the present application, Figure 6 As shown, the second shell 14 has an intermediate position during the movement between the deployed position and the retracted position relative to the first shell 12. When the second shell 14 is in the intermediate position, the area between the corresponding first side wall 12a and the second side wall 14a of the shell assembly 10 defines the detection area 10a. The intermediate position can be the position of the second shell 14 at the moment of leaving the deployed position. At this time, the distance between the intermediate position and the deployed position is close to 0. Ignoring the error, the intermediate position can be considered to be the same as the deployed position. Of course, in some embodiments, the intermediate position is the same as the deployed position. The intermediate position and the deployed position are distinguished only to facilitate the understanding of the detection area 10a.

[0063] Combination Figure 2 and Figure 4 As shown, in the embodiment of the present application, the electronic device 100 includes a shielding member 40 , a first radiator 50 , a second radiator 60 , a capacitive sensor 70 and a controller 80 .

[0064] The shielding member 40 is connected to the shell assembly 10 and electrically grounded to shield the second radiator 60 so that the second radiator 60 is not interfered by the outside world when it works. For example, when a finger is placed in the detection area 10a, the finger will not interfere with the second radiator 60.

[0065] For ease of description, the area where the shielding member 40 performs a shielding function is referred to as a "shielding area". The shielding area is located outside the detection area 10a, so that the structure located at a corresponding position of the shielding area will not be affected by the components in the detection area 10a.

[0066] In this embodiment, the first radiator 50 and the second radiator 60 are both connected to the shell assembly 10, wherein the first radiator 50 corresponds to the detection area 10a, and the second radiator 60 corresponds to the shielding area. Since the shielding area formed by the shielding member 40 is located outside the detection area 10a and can play a good shielding role, the first radiator 50 and the second radiator 60 work in the corresponding detection area 10a and the shielding area respectively without interfering with each other.

[0067] Specifically, the first radiator 50 and the second radiator 60 are both electrically connected to the capacitive sensor 70, and the capacitive sensor 70 can obtain a capacitance value in the detection area 10a via the first radiator 50, and the capacitive sensor 70 can obtain a capacitance value in the shielding area via the second radiator 60. Based on the different setting positions of the first radiator 50 and the second radiator 60, and the second radiator 60 corresponds to the shielding area of ​​the shielding member 40, when the electronic device 100 is in different states, the capacitance value obtained by the capacitive sensor 70 via the first radiator 50 will also be different from the capacitance value obtained by the capacitive sensor 70 via the second radiator 60.

[0068] For ease of description, the capacitance value obtained by the capacitance sensor 70 through the first radiator 50 is referred to as a “first capacitance value”, and the capacitance value obtained by the capacitance sensor 70 through the second radiator 60 is referred to as a “second capacitance value”.

[0069] Since the first radiator 50 is disposed corresponding to the detection area 10a, when a finger or foreign object is placed in the detection area 10a, the first capacitance value will change accordingly, so that it can be determined whether there is a finger or foreign object in the detection area 10a according to the first capacitance value.

[0070] The inventors have discovered that at a specific temperature (e.g., 40°C to 60°C), even if no finger or foreign object is placed in the detection area 10a, the detection area 10a may still be judged as having a finger or foreign object based on the first capacitance value. That is to say, under the influence of temperature, judging whether there is a finger or foreign object in the detection area 10a based on the first capacitance value may result in the presence of a foreign object.

[0071] Therefore, the inventor proposes a technical solution of the embodiment of the present application, using the shielding area provided by the second radiator 60 in the shielding member 40 to construct a channel for the capacitive sensor 70 to obtain the second capacitance value, based on the fact that the second radiator 60 will not be affected by the detection area 10a in the shielding area, therefore, the second capacitance value will not be affected by whether fingers or foreign objects are placed outside the shielding area, and can reflect the influence of temperature on the capacitance value. In this way, the second capacitance value can be used to perform temperature compensation on the first capacitance value, so as to eliminate the influence of temperature on the first capacitance value.

[0072] Specifically, the controller 80 is electrically connected to the capacitance sensor 70, and the controller 80 is used to perform a temperature-effect shielding process on the first capacitance value according to the second capacitance value to obtain a third capacitance value. The temperature-effect shielding process refers to shielding the effect of temperature on the second capacitance value. In this embodiment, the controller 80 is also used to control the working state of the driving mechanism 30, so that the driving mechanism 30 drives the second shell 14 to move relative to the first shell 12.

[0073] In the embodiment of the present application, when the second shell 14 moves toward the retracted position, in order to avoid the second shell 14 continuing to move toward the retracted position when the finger is in the detection area 10a and causing the finger to be pinched. The controller 80 can feedback control the drive mechanism 30 according to the third capacitance value. Specifically, when the second shell 14 moves toward the retracted position, if the third capacitance value exceeds the preset range, the controller 80 controls the drive mechanism 30 to drive the second shell 14 to move toward the extended position relative to the first shell 12 or controls the drive mechanism 30 to stop driving the second shell 14 to move relative to the first shell 12, so as to avoid the second shell 14 continuing to move toward the retracted position and pinching the finger or foreign object located in the detection area 10a.

[0074] It should be noted that the preset range can be set according to the third capacitance value measured by the capacitance sensor 70 when a finger or foreign object is placed in the detection area 10a. In this way, by comparing the third capacitance value with the preset range, it can be determined whether a finger or foreign object is placed in the detection area 10a.

[0075] In the case where a finger or foreign object is present in the detection area 10a, the third capacitance value exceeds the preset range. The driving mechanism 30 will no longer continue to drive the second housing 14 to move toward the retracted position relative to the first housing 12, effectively reducing the probability of the user's finger being pinched and also preventing the driving mechanism 30 from being damaged by a large reaction force.

[0076] In some embodiments, the capacitive sensor 70 may be a SAR sensor to sense the SAR (Specific Absorption Rate) value through the first radiator 50 and the second radiator 60. Taking the capacitive sensor 70 detecting the detection area 10a through the first radiator 50 as an example, if a finger is placed in the detection area 10a, an induced electromagnetic field will be generated in the human body under the action of the external electromagnetic field. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. Therefore, when a finger approaches the detection area 10a, the SAR value will change relative to when there is no finger approaching the detection area 10a. This change in the SAR value will be characterized by a change in the capacitance of the capacitive sensor 70.

[0077] In the embodiment of the present application, since the third capacitance value is the capacitance value after the first capacitance value is subjected to the temperature-effect shielding treatment, to be precise, the first capacitance value is subjected to the temperature-effect shielding treatment according to the second capacitance value, and the influence of temperature on the capacitance value is excluded from the first capacitance value, the third capacitance value thus obtained can accurately characterize that the capacitance change of the detection area 10a is caused by the placement of a finger or foreign object in the detection area 10a, rather than by temperature. This reduces the probability of misjudging the situation where a finger or foreign object is not placed in the detection area 10a due to the influence of temperature as a finger or foreign object is placed in the detection area 10a, and improves the accuracy of the controller 80 in controlling the working state of the drive mechanism 30.

[0078] For ease of understanding, the electronic device 100 does not include the second radiator 60 and uses the first capacitance value to determine whether a finger or foreign matter is placed in the detection area 10 a as a comparative example for comparison and explanation.

[0079] Specifically, if the capacitance value obtained by the capacitance sensor 70 exceeds P when the second housing 14 moves toward the retracted position, it is considered that there is a finger or foreign object in the detection area 10a. At this time, the controller 80 will control the driving mechanism 30 to stop driving the second housing 14 toward the retracted position. If the temperature is 40°C to 60°C, the first capacitance value detected by the capacitance sensor 70 in the detection area 10a through the first radiator 50 is greatly affected by the temperature and exceeds the capacitance value P, but in fact there is no finger or foreign object in the detection area 10a. Then, judging that there is a finger or foreign object in the detection area 10a based on the first capacitance value is a misjudgment. At this time, the controller 80 is affected by the misjudgment result and controls the driving mechanism 30 to stop driving the second housing 14 toward the retracted position, resulting in the electronic device 100 being unable to be retracted normally.

[0080] In the embodiment of the present application, since the second radiator 60 is provided corresponding to the shielding area formed by the shielding member 40, the second capacitance value obtained by the capacitance sensor 70 through the second radiator 60 will not be affected by elements such as fingers and the first radiator 50, so as to accurately reflect the capacitance value under the influence of temperature. Therefore, the controller 80 obtains the third capacitance value by performing temperature-impact shielding processing on the first capacitance value according to the second capacitance value, which can shield the influence of temperature on the capacitance value, so as to accurately reflect whether there is a finger or foreign matter in the detection area 10a, so that the controller 80 can accurately control the movement of the second shell 14 according to the third capacitance value, reduce the misjudgment caused by the temperature influence, and enable the electronic device 100 to be normally folded when there is no finger or foreign matter in the detection area 10a, thereby improving the user experience.

[0081] In some embodiments, in combination Figure 6As shown, the displacement of the second shell 14 from the unfolded position to the middle position is the first displacement D1, and the displacement of the second shell 14 from the middle 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) accounts for a suitable proportion of the overall movement stroke of the second shell 14 relative to the first shell 12. In some embodiments, when the driving mechanism 30 drives the second shell 14 to move from the middle position to the folded position relative to the first shell 12, the capacitive sensor 70 obtains the first capacitance value through the first radiator 50, that is, the capacitive sensor 70 performs detection during the second displacement D2 of the second shell 14, and does not need to detect the detection area 10a during the first displacement D1 of the second shell 14, so as to reduce power consumption.

[0082] In some embodiments, the value range of the second displacement D2 is 0.5 cm to 2.0 cm, such as 0.5 cm, 0.7 cm, 0.9 cm, 1.2 cm, 1.5 cm, 1.7 cm, 1.9 cm or 2.0 cm. In this embodiment, the value range of the second displacement D2 is controlled to be 1.2 cm to 2.0 cm, which can ensure that the detection area 10a has a sufficient detection width in the first direction to avoid the capacitive sensor 70 performing detection only after the finger is pinched, and at the same time, it can avoid the detection area 10a having a sufficient detection width in the first direction being too large, resulting in unnecessary energy waste.

[0083] In some embodiments, the controller 80 is electrically connected to an antenna switch and a radio frequency processing circuit, and the antenna switch is connected between the second radiator 60 and the radio frequency processing circuit, and is used to switch the working state of the second radiator 60. Specifically, when the second housing 14 is in the unfolded position, the antenna switch electrically connects the second radiator 60 to the radio frequency processing circuit, and the radio frequency processing circuit can transmit radio frequency signals through the second radiator 60, thereby improving the signal transmission efficiency of the electronic device 100 during the unfolding and use of the flexible screen 20. When the second housing 14 leaves the unfolded position, the antenna switch disconnects the second radiator 60 from the radio frequency processing circuit. Specifically, the second radiator 60 and the radio frequency processing circuit are in a state of electrical signal disconnection. At this time, the capacitive sensor 70 can stably sense the capacitance change in the shielding area through the second radiator 60. The antenna switch can be a switch element built into the electronic device 100, which is controlled by the controller 80. In some embodiments, the user can control the antenna switch by pressing a button of the electronic device 100, and then the user can turn on or off the function of transmitting radio frequency signals by the second radiator 60 according to actual needs.

[0084] The first radiator 50 may be connected to the first housing 12 and fixed relative to the first side wall 12 a , or may be connected to the second housing 14 and fixed relative to the second side wall 14 a .

[0085] The second radiator 60 can be fixedly connected to the first housing 12 or the second housing 14 , as long as the second radiator 60 is disposed corresponding to the shielding area formed by the shielding member 40 .

[0086] See again Figure 2 and Figure 4 As shown, the shell assembly 10 includes a plate 16. When the second shell 14 is in the unfolded position, the plate 16 is at least partially exposed between the first side wall 12a and the second side wall 14a, 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 using the plate 16. Specifically, when the second shell 14 is in the unfolded position, the plate 16 can provide the appearance surface of the electronic device 100 to maintain the appearance integrity of the electronic device 100. It can be understood that when the second shell 14 is in the folded position, the plate 16 is hidden in the first shell 12 and the second shell 14. At this time, the first shell 12 and the second shell 14 constitute the appearance surface of the electronic device 100.

[0087] The plate 16 may be integrally formed with the second housing 14, or connected to the second housing 14 by glue or screws. In other embodiments, the first housing 12 and the second housing 14 are both slidably connected to the plate 16, so that the plate 16 can be used to provide stable support for the sliding between the first housing 12 and the second housing 14.

[0088] Continue reading Figure 2 and Figure 4 As shown, the electronic device 100 is provided with a traction member 90, which is arranged at one end of the first shell 12 away from the second shell 14. When the second shell 14 switches from the retracted position to the unfolded position relative to the first shell 12, the traction member 90 can tractionally deform the flexible screen 20 so that the part of the flexible screen 20 unfolded in the second shell 14 is flat. When the second shell 14 is in the retracted position, the free end 204 of the flexible screen 20 bypasses the traction member 90, and the traction member 90 can limit the bending radius of the flexible screen 20 to an appropriate range to avoid damage to the flexible screen 20 due to a too small bending radius. Of course, the traction member 90 can also prevent the bending radius of the flexible screen 20 from being too large, causing the thickness of the electronic device 100 to be too large.

[0089] In some embodiments, the traction member 90 may be a rotating shaft structure with convex teeth, and the flexible screen 20 is linked to the traction member 90 by means of engagement or the like. When the second shell 14 slides relative to the first shell 12, the traction member 90 drives the part of the flexible screen 20 engaged with the traction member 90 to move and be extended from or retracted into the shell assembly 10.

[0090] In other embodiments, the traction member 90 is a round shaft without teeth. When the second shell 14 is switched from the folded position to the unfolded position, the part of the flexible screen 20 attached to the traction member 90 is stretched open by the traction member 90, so that more of the flexible screen 20 is exposed to the outside of the shell assembly 10 and remains flat. In this embodiment, the traction member 90 can be rotatably arranged on the second shell 14. In the process of gradually unfolding the flexible screen 20, the traction member 90 can rotate with the movement of the flexible screen 20 to reduce the resistance encountered by the flexible screen 20 during the unfolding process and reduce the wear of the contact part between the traction member 90 and the flexible screen 20.

[0091] In some embodiments, the traction member 90 may also be fixed on the first shell 12, and the traction member 90 has a smooth surface. In the process of unfolding the flexible screen 20, the traction member 90 can slidably contact the flexible screen 20 through its smooth surface. In other words, in this embodiment, the traction member 90 can be integrally formed or welded with the first shell 12, and the traction member 90 can be regarded as a part of the first shell 12, and the free end 204 of the flexible screen 20 bypasses the end of the first shell 12 away from the second shell 14 and extends into the shell assembly 10.

[0092] In the embodiment where the housing assembly 10 includes the plate body 16 , the plate body 16 is provided with a first radiator 50 and a second radiator 60 .

[0093] Combination Figures 7 to 9 As shown, the side 16a of the plate 16 facing away from the flexible screen 20 and the side 16b of the plate 16 facing the flexible screen 20 are both provided with a first radiator 50. In some embodiments, only one of the side 16a of the plate 16 facing away from the flexible screen 20 and the side 16b of the plate 16 facing the flexible screen 20 is provided with the first radiator 50.

[0094] The second radiator 60 may be disposed at a position of the first housing 12 overlapping the plate 16, or at a position of the second housing 14 overlapping the plate 16. The overlapping position of two objects refers to the overlapping area of ​​the orthographic projections of the two objects in the detection area 10a.

[0095] Accordingly, the second radiator 60 can be placed outside the detection area 10a. Figure 8As shown, in some embodiments, the second radiator 60 is fixedly connected to the first shell 12, and can be specifically embedded in the first shell 12, or can be adhered to at least one of the inner surface and the outer surface of the first shell 12 by glue, wherein the inner surface of the first shell 12 is the surface of the first shell 12 facing the interior of the electronic device 100.

[0096] It should be noted that, in some embodiments, the shielding member 40 includes a first shielding portion 40a and a second shielding portion 40b that are perpendicular to each other, and the first shielding portion 40a is disposed between the second radiator 60 and the back of the shell assembly 10, so that when the user uses the electronic device 100, the finger touches the back of the shell assembly 10 corresponding to the position of the second radiator 60, and the first shielding portion 40a can play a shielding effect to prevent the finger from affecting the second capacitance value. The second shielding portion 40b is located between the first radiator 50 and the second radiator 60, thereby further avoiding interference between the first radiator 50 and the second radiator 60.

[0097] The material of the shielding member 40 is not limited, as long as it can shield radiation. For example, the shielding member includes at least one of copper foil and aluminum-magnesium alloy film. When the shielding member includes both aluminum foil and aluminum-magnesium alloy film, the aluminum foil and the aluminum-magnesium alloy film can be stacked on each other, can be spaced apart from each other, or can be spliced ​​together.

[0098] Combination Figure 7 and Figure 8 As shown, in some embodiments, at least one of the first side wall 12a and the second side wall 14a is provided with a buffer 18, and the material of the buffer 18 can be rubber, latex, EVA (Ethylene VinylAcetate) or EPS (Expanded Polystyrene) or the like. By utilizing the good buffering performance of the buffer 18, the electronic device 100 as a whole has good anti-fall performance when the second shell 14 is in the retracted position. Specifically, since the buffer 18 is located between the first side wall 12a and the second side wall 14a, when the second shell 14 is in the retracted position, the buffer 18 can reduce the hard collision between the first side wall 12a and the second side wall 14a to achieve a buffering effect.

[0099] In the embodiment where the first side wall 12a is provided with a buffer 18, the first radiator 50 may be provided on the side of the buffer 18 facing away from the first side wall 12a. Accordingly, in the embodiment where the second side wall 14a is provided with a buffer 18, the first radiator 50 may be provided on the side of the buffer 18 facing away from the second side wall 14a.

[0100] The first radiator 50 and the second radiator 60 can be made of the same material. Specifically, in order to obtain a good detection effect, the first radiator 50 and the second radiator 60 are antennas. The second radiator 60 is taken as an example for description.

[0101] The first radiator 50 can be an FPC antenna, which is an antenna made on a corresponding structural member using the FPC process. Specifically, the technical principle of the FPC process is to use a printed circuit board with a pattern made of a flexible substrate, which is composed of an insulating substrate and a conductive layer. There can be an adhesive between the insulating substrate and the conductive layer, and it is pasted to the position where the antenna needs to be set. The FPC antenna is thin and light, has good bendability, and is low in cost. In this embodiment, the FPC antenna can be set in the first shell 12 or in the second shell 14, as long as it can be opposite to the detection area 10a and meet the need of the capacitive sensor 70 to sense the SAR value of the detection area 10a through the first radiator 50.

[0102] In some embodiments, the first radiator 50 may be a PDS antenna, which is an antenna made on a corresponding structural member using a PDS process. Specifically, a conductive silver paste is applied to the surface of a structure such as the first side wall 12a, the second side wall 14a, the plate 16 or the buffer 18, and then the silver paste is printed in multiple layers to form a conductive three-dimensional circuit, and then the final first radiator 50 is made by thermal curing. Since the PDS antenna can directly print the circuit, no special laser modified materials are required, which can reduce costs.

[0103] It should be noted that in the above-mentioned embodiments, the shielding member 40, the first radiator 50, the second radiator 60, the capacitive sensor 70 and the controller 80 of the electronic device 100 of the present application can effectively prevent the first shell 12 and the second shell 14 from pinching the user's fingers when they move relative to each other, and can reduce the probability that the capacitive sensor 70 will misjudge the situation where there is no finger or foreign object in the detection area 10a due to temperature interference when detecting the detection area 10a. It is understandable that the flexible screen 20 is not necessary for the electronic device 100 to achieve the purpose of anti-pinching, that is, in some embodiments of the electronic device 100, the flexible screen 20 can be omitted.

[0104] Based on the above-mentioned electronic device 100 , another embodiment of the present application provides a control method for controlling the above-mentioned electronic device 100 . The control method can effectively prevent the user's fingers from being pinched when using the electronic device 100 .

[0105] Specifically, combined Fig.10 As shown, the control method includes the following steps:

[0106] Step S102 , receiving control operation information, and controlling the driving mechanism 30 to drive the second shell 14 to move toward the retracted position according to the control operation information.

[0107] It should be noted that, in an embodiment where the electronic device 100 includes a flexible screen 20, the operation control information is a control instruction related to controlling the folding operation of the flexible screen 20. For example, the control operation information may be input into the electronic device 100 by a user clicking, sliding, or dragging the operation interface of the flexible screen 20, or may be input by operating a button of the electronic device 100. In some application scenarios, when a user slides two fingers on the flexible screen 20 in a direction approaching each other, the drive mechanism 30 will drive the second shell 14 to move toward the folded position relative to the first shell 12 to fold the flexible screen 20. In an embodiment where the electronic device 100 does not include a flexible screen 20, the operation control information may be a control instruction related to the movement of the second shell 14 relative to the first shell 12 toward the folded position.

[0108] In step S104 , the capacitance sensor 70 of the electronic device 100 obtains a first capacitance value in the detection area 10 a through the first radiator 50 , and obtains a second capacitance value in the shielding area through the second radiator 60 .

[0109] Based on the first radiator 50 being set corresponding to the detection area 10a, and the second radiator 60 being set corresponding to the shielding area, the capacitance sensor 70 will not be affected when acquiring the first capacitance value and the second capacitance value. Moreover, since the first radiator 50 and the second radiator 60 are both in the electronic device 100, the overall environmental difference between the two is small. When the temperature of the first radiator 50 changes, the temperature of the second radiator 60 will also change. Accordingly, when the temperature changes, the first capacitance value is affected, and the second capacitance value is also affected. Therefore, it can be understood that the first capacitance value and the second capacitance value can obtain capacitance changes that are not caused by temperature changes, as shown in the following step S106.

[0110] Step S106: performing temperature impact shielding processing on the first capacitance value according to the second capacitance value to obtain a third capacitance value.

[0111] Since the third capacitance value is the capacitance value after the first capacitance value is subjected to temperature-effect shielding processing, to be precise, the influence of temperature on the first capacitance value is eliminated, so that the third capacitance value can reflect the capacitance change caused by non-temperature factors.

[0112] In some embodiments, the following conditions are met:

[0113] X=X1+δX2;

[0114] Among them, X1 is the first capacitance value, X2 is the second capacitance value, X is the third capacitance value, δ is an accompanying weight of the second capacitance value corresponding to the first capacitance value under the influence of temperature, and δ can be optimized and adjusted according to actual test conditions and is not limited here.

[0115] Since the second capacitance value is affected by temperature when the first capacitance value is affected by temperature, after the first capacitance value is shielded from temperature influence according to the second capacitance value, the influence of temperature on the capacitance value can be eliminated, thereby achieving the effect of temperature compensation, so that the obtained third capacitance value can accurately reflect the radiation absorption situation of the detection area 10a when it is not affected by temperature, so as to accurately judge whether there is a finger or foreign object in the detection area 10a.

[0116] Step S108 , if the third capacitance value exceeds the preset range, the driving mechanism 30 is controlled to drive the second housing 14 to move toward the unfolded position or the driving mechanism 30 is controlled to stop driving the second housing 14 to move.

[0117] The preset range can be set according to the third capacitance value measured by the capacitance sensor 70 in an environment where a finger or foreign object is placed in the detection area 10a. In this way, by comparing the third capacitance value with the preset range, it can be determined whether a finger or foreign object is placed in the detection area 10a. Since the third capacitance value exceeds the preset range when a finger or foreign object is present in the detection area 10a, the drive mechanism 30 will no longer continue to drive the second shell 14 to move toward the retracted position relative to the first shell 12, thereby effectively reducing the probability of the user's finger being pinched, and at the same time, it also avoids the drive mechanism 30 from being damaged by a large reaction force.

[0118] Combination Fig.11 As shown, in some embodiments, after obtaining the third capacitance value, specifically, after step S106, by determining whether the third capacitance value exceeds a preset range, it can be determined whether there is a finger or foreign object in the detection area 10a, so that the electronic device 100 can perform subsequent operations.

[0119] Specifically, if the third capacitance value exceeds the preset range, step S108 is executed. Otherwise, step S110 is executed to control the driving mechanism 30 to drive the second housing 14 to move toward the retracted position.

[0120] When a finger or foreign object appears in the detection area 10a, the third capacitance value exceeds the preset range, and the driving mechanism 30 will no longer continue to drive the second shell 14 to move toward the retracted position relative to the first shell 12, thereby effectively reducing the chance of the user's finger being pinched. At the same time, it also avoids the driving mechanism 30 from being damaged by a large reaction force.

[0121] In some embodiments, in an embodiment where the electronic device 100 includes a flexible screen 20, the controller 80 is electrically connected to the flexible screen 20, and the flexible screen 20 can be used to provide prompt information to remind the user that an abnormality occurs during the folding process of the electronic device 100.

[0122] Specifically, the control method further comprises the steps of:

[0123] If the third capacitance value exceeds the preset range, the flexible screen 20 is controlled to display a reminder interface to remind the user that there is an abnormality in the detection area 10a.

[0124] It should be noted that the method of reminding the user that the detection area 10a has an abnormality may be a graphic or animation. For example, when the detection area 10a has a hand-pinching abnormality, the flexible screen 20 displays an image or animation of the hand being pinched to remind the user vividly, and the reminder method is also interesting. In some embodiments, the user may be reminded that the detection area 10a has an abnormality by text or a flashing display.

[0125] It should be noted that, in some embodiments, the capacitive sensor 70 may continuously or intermittently obtain the first capacitance value and the second capacitance value through the first radiator 50 and the second radiator 60 during the entire process of the second shell 14 moving toward the retracted position relative to the first shell 12, or during the process of the second shell 14 moving from the intermediate position to the retracted position relative to the first shell 12.

[0126] Combination Fig.12 As shown, step S106, i.e., performing temperature-effect shielding processing on the first capacitance value according to the second capacitance value to obtain a third capacitance value, includes:

[0127] Step S1062, obtaining the temperature shielding weight.

[0128] Step S1064, obtaining a shielding capacitance value according to the temperature shielding weight and the second capacitance value, and obtaining a third capacitance value according to the first capacitance value and the shielding capacitance value.

[0129] Furthermore, combined with Fig.13 As shown, step S1062, i.e., the step of obtaining the temperature shielding weight, includes:

[0130] Step S1062a, obtaining the direction in which the temperature affects the capacitance value of the capacitance sensor 70.

[0131] In some embodiments, as the temperature increases, the capacitance value obtained by the capacitance sensor 70 increases, in which case the direction of influence can be considered to be positive, and correspondingly, as the temperature increases, the capacitance value obtained by the capacitance sensor 70 decreases, in which case the direction of influence can be considered to be negative. Understandably, in the process of temperature increase, the capacitance value may increase first and then decrease, or may continue to increase or continue to decrease, or may first decrease and then increase. The direction of the influence of temperature on the capacitance value of the capacitance sensor 70 is not limited herein.

[0132] Step S1062b, obtaining a weight opposite to the influencing direction as a temperature shielding weight.

[0133] It should be noted that the weight and the direction of influence are opposite to each other, which means that the direction of influence of the capacitance value is opposite to the direction of influence of the weight on the capacitance value. Therefore, when the temperature affects the capacitance value of the capacitance sensor 70, temperature compensation can be performed to shield the capacitance value change caused by the temperature to obtain a third capacitance value, which truly reflects whether there is a finger or foreign matter in the detection area 10a, so that the controller 80 can accurately control the working state of the driving mechanism 30, thereby improving the user experience.

For example, in an embodiment of the present invention, a computer-readable storage medium is provided, on which computer-readable instructions are stored.
