(5) Conventional laptop and/or palmtop radiotelephone transceivers, and the like.
Referring to fig. 1 to 4, an electronic device 100 according to an embodiment of the present application includes a housing assembly 10 and a flexible screen 20. The housing assembly 10 forms a receiving cavity 101 and the flexible screen 20 is coupled to the housing assembly 10. The electronic device 100 may further include a circuit board (not shown) and a battery (not shown), both of which may be disposed in the receiving cavity 101 of the housing assembly 10. The circuit board may integrate a processor, a power management module, a memory unit, a baseband chip, and the like of the electronic device 100. The flexible screen 20 is communicatively connected to the processor and the battery is capable of powering the flexible screen 20 and the electronics on the circuit board. Of course, the electronic device 100 may further include a camera module (not shown), the camera module is connected to the circuit board in communication, 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.
The shell assembly 10 includes a first shell 12 and a second shell 14 that are movably coupled, the second shell 14 and the first shell 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 and second housings 12, 14 are moved relative to each other in the first direction, the flexible screen 20 is extended from or retracted into 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 slidable relative to the first housing 12. For example, one of the first and second housings 12, 14 may be provided with a slide rail along which the other is slidable to enable the first and second housings 12, 14 to move telescopically with respect to each other. In other embodiments, the second housing 14 and the first housing 12 may be movably connected by other structures capable of moving telescopically along 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 as to realize the movable connection between the first casing 12 and the second casing 14 along the first direction. 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, when the second housing 14 is in the folded position, the electronic device 100 has a relatively small external size and is convenient to carry. With reference to fig. 3 and fig. 4, when the second casing 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 a use experience of the electronic device 100. Therefore, with this arrangement, the area of the display screen (hereinafter referred to as the display interface 20 a) of the flexible screen 20 can be adjusted by relative sliding and expansion of the first casing 12 and the second casing 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 substantially rectangular, and may have a size of 4.5 inches to 7 inches, which is equivalent to a display screen of a typical smart phone, so that the electronic device 100 is convenient to carry and use.
It should be noted that, the flexible screen 20 is used as a display or touch-control structural member of the electronic device 100, and has a display area, where the display area refers to an area corresponding to a maximum display screen of the flexible screen 20, or in a relative sliding and stretching process of the first casing 12 and the second casing 14, when the second casing 14 is located at an extended position, that is, when the display interface 20a is at a maximum, the display interface 20a is the same as the display area. Since a portion of the display area of the flexible screen 20 is accommodated inside without being exposed during sliding and extending of the first casing 12 and the second casing 14 relative to each other, the portion does not present a display screen. The display interface 20a refers to a portion of the display area exposed to the first casing 12 and the second casing 14. When the display interface 20a is then lit or displays a screen, the content displayed on the display interface 20a can be viewed from the outside of the electronic device 100.
It is understood that in the embodiments described later in this application, the folded position, the unfolded position and the like refer to the relative positions of the second casing 14 and the first casing 12. For simplicity, similar expressions of "the second housing 14 is in the stowed position" or "in the stowed position" refer to the second housing 14 being in the stowed 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 fig. 2 and 4, the flexible screen 20 may include a fixed end 202 and a free end 204, the fixed end 202 is disposed on the second housing 14 and fixed relative to 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 second housing 14 is in the collapsed position, free end 204 of flexible screen 20 is received within housing assembly 10 such that portions of flexible screen 20 are hidden from housing assembly 10, and portions of flexible screen 20 hidden from housing assembly 10 may not be used for display. As shown in fig. 4, the structure of the portion of the flexible screen 20 proximate the free end 204 gradually unfolds from the shell assembly 10 as the second housing 14 moves relative to the first housing 12 toward the deployed position. In other embodiments, the fixed end 202 is disposed on the first housing 12 and fixed relative to the position of the first housing 12, and the free end 204 moves in the receiving cavity 101 of the shell assembly 10 as the second housing 14 moves relative to the first housing 12, so that a portion of the flexible screen 20 is exposed from or received in the receiving cavity 101 of the shell assembly 10.
It is understood that in the embodiments of the present application, the two objects are fixed relative to each other, that is, the two objects cannot move relative to each other under normal conditions, and the two objects fixed relative to each other may be directly connected physically or indirectly connected through an intermediate structure. Taking the fixed end 202 and the second housing 14 as an example, the fixed end 202 and the second housing 14 are relatively fixed, the fixed end 202 may be directly contacted with the second housing 14, for example, the fixed end 202 and the second housing 14 are directly fixed by using a threaded fastener or a clamping manner, or the fixed end 202 and the second housing 14 are indirectly fixed by using an adhesive layer, an intermediate connecting plate, or other structures.
The second housing 14 may further include a rear cover 141, the rear cover 141 covering the free end 204 of the flexible screen 20 when in the deployed position.
Further, the rear cover 141 may be provided with a light-transmitting area, and the portion of the flexible screen 20 accommodated in the housing assembly 10 in the unfolded position may also be used for displaying, so that a user can view information displayed on the flexible screen 20 from the light-transmitting area, thereby expanding a use scene of the electronic device 100. For example, in this embodiment, the electronic device 100 can implement functions such as self-shooting, video call, etc. by using a rear camera module without providing a front camera. The light-transmitting area may be made of transparent glass or may be formed by an opening of the rear cover 141. After the second housing 14 is moved to the collapsed position relative to the first housing 12, at least a portion of the flexible screen 20 housed in the housing assembly 10 is exposed. The exposed flexible screen 20 may be used for display, so that the electronic device 100 has a relatively large display area to enhance the user experience.
Continuing to refer to fig. 2 and 4, electronic device 100 includes drive mechanism 30. The driving mechanism 30 is disposed in the receiving cavity 101 of the shell assembly 10 and is used for driving the first shell 12 and the second shell 14 to move relatively along a first direction, so that the second shell 14 drives the flexible screen 20 to be released from or retracted into the shell assembly 10 from the shell assembly 10.
In some embodiments, the first housing 12 and the second housing 14 are connected to the driving mechanism 30 and move relative to each other under the driving of the driving mechanism 30. Specifically, the driving mechanism 30 has a fixed portion and a movable portion, and the movable portion is movable relative to the fixed portion when the driving mechanism 30 is operated. The fixed portion is connected with the first housing 12, and the movable portion is connected with the second housing 14 and is used for driving the second housing 14 to move relative to the first housing 12.
It should be noted that the driving mechanism 30 may be a belt transmission structure or a gear transmission structure, or may be a telescopic transmission structure such as an air cylinder, and the structure of the driving mechanism 30 is not limited herein as long as the driving mechanism 30 can drive the first housing 12 and the second housing 14 to move relatively to adjust the extending length of the flexible screen 20 in the first direction.
The inventors have found that adjusting the deployed length of flexible screen 20 in a first direction is achieved by relative movement of first housing 12 and second housing 14 such that flexible screen 20 is deployed out of housing assembly 10 or stowed in housing assembly 10, however, there is a risk of first housing 12 and second housing 14 pinching the user's fingers when moving to the stowed position. For the sake of understanding, referring to fig. 5, an area of the back surface of the housing assembly 10 where there is a risk of hand pinching during folding of the flexible screen 20 of the electronic device 100 is referred to as a "detection area 10a", and it is understood that the detection area 10a is an area where fingers or foreign matter are not expected to be present during folding of the flexible screen 20. The back of the housing assembly 10 refers to a surface of the housing assembly 10 exposed on a side of the electronic device 100 facing away from the display interface 20a, and understandably, since the first housing 12 and the second housing 14 can move relatively in the first direction, the surface of the housing assembly 10 exposed on the electronic device 100 becomes larger or smaller along with the relative movement of the first housing 12 and the second housing 14, and specifically, the width of the detection area 10a in the first direction gradually decreases as the second housing 14 moves toward the folded position.
In some embodiments, as shown in fig. 5 and 6, in the first direction, the first housing 12 has a first sidewall 12a facing the side where the second housing 14 is located, and the second housing 14 has a second sidewall 14a facing the side where the first housing 12 is located. Understandably, when 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 casing 14 is in the folded position, the first sidewall 12a contacts the second sidewall 14a, so that the first casing 12 and the second casing 14 are aligned in a seam, and the overall appearance texture of the electronic device 100 is maintained. Understandably, in some embodiments, when the second housing 14 is in the folded position, a gap may also exist between the first side wall 12a and the second side wall 14a, the width of the gap is less than or equal to 1mm, the width of the gap is controlled within the range, and the seam line between the first side wall 12a and the second side wall 14a is negligibly small, so that even when 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 device 100 is small.
In some embodiments, the first sidewall 12a and the second sidewall 14a are spaced apart from each other when the electronic device is in a certain state, defining a detection zone therebetween. The width of the detection area in the first direction is not limited herein. It will be appreciated that the detection zone may be an area where a user may inadvertently place a finger between the first and second sidewalls 12a, 14a while moving the second housing 14 toward the stowed position relative to the first housing 12, at risk of being pinched by the first and second sidewalls 12a, 14a. In addition, when a foreign object is caught 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 may receive a large resistance, and accordingly, the driving mechanism 30 may also receive a large reaction force, in which case, the driving mechanism 30 may be easily damaged, which may cause the overall mechanism performance of the electronic apparatus 100 to be degraded, and may even cause the electronic apparatus 100 to be scrapped.
In particular to the embodiment of the present application, as shown in fig. 6, the second housing 14 has an intermediate position during movement between the deployed position and the stowed position relative to the first housing 12, with the second housing 14 in the intermediate position, the area of the housing assembly 10 between the corresponding first and second sidewalls 12a, 14a defining the detection zone 10a. The intermediate position may be a position at the moment when the second casing 14 is separated from the deployed position, and in this case, the distance between the intermediate position and the deployed position is close to 0. Of course, in some embodiments, the intermediate position is the same as the deployed position, and the intermediate position and the deployed position are distinguished only for ease of understanding of the detection zone 10a.
In the present embodiment, the electronic device 100 includes a first radiator 40, a second radiator 50, a capacitive sensor 60, and a controller 70.
The first radiator 40 is disposed on the housing assembly 10 and outside the detection area 10a, and the second radiator 50 is disposed on the housing assembly 10 and outside the detection area 10a. Specifically, the first radiator 40 may be disposed on the first casing 12 or the second casing 14, and in some embodiments, as shown in fig. 5, a plurality of first radiators 40 are provided, some of the first radiators 40 may be disposed on the first casing 12, and some of the first radiators 40 may be disposed on the second casing 14. The position of the first radiator 40 is not limited herein as long as the first radiator 40 is located outside the detection area 10a.
Accordingly, the second radiator 50 may be disposed at any position within the detection region 10a. For example, as shown in fig. 5, in some embodiments, the second radiator 50 is connected to the first case 12 and fixed opposite to the first sidewall 12 a.
The first radiator 40 and the second radiator 50 are both electrically connected to the capacitive sensor 60, so that the capacitive sensor 60 can obtain a capacitance value outside the detection area 10a through the first radiator 40, and obtain a capacitance value inside the detection area 10a through the second radiator 50 by using the capacitive sensor 60, and based on the different arrangement positions of the first radiator 40 and the second radiator 50, when the electronic device 100 is in different states, the capacitance value obtained by the capacitive sensor 60 will be different.
For convenience of description, the capacitance value obtained by the capacitive sensor 60 through the first radiator 40 is referred to as a "first capacitance value", and the capacitance value obtained by the capacitive sensor 60 through the second radiator 50 is referred to as a "second capacitance value".
In some embodiments, when the electronic device 100 is placed on a metal table, the electronic device 100 is affected by the metal table, the first capacitance value obtained by the capacitive sensor 60 through the first radiator 40 is larger than that obtained before the electronic device 100 is placed on the metal table, so that whether the electronic device 100 is placed on the metal table can be known according to the first capacitance value. The metal table top includes, but is not limited to, a table top, a counter top or a machine tool table top made of metal.
Because the second radiator 50 is disposed in the detection region 10a, the capacitance sensor 60 is also affected by whether a finger or a foreign object exists in the detection region 10a through the second capacitance value obtained by the second radiator 50, so that whether a finger or a foreign object exists in the detection region 10a can be known according to the second capacitance value.
It can be understood that different objects have different effects on the capacitance value obtained by the capacitance sensor 60, for example, when the electronic device is placed on a metal table, the metal table has a larger effect on the capacitance value of the capacitance sensor 60 than when a finger is placed on the detection area 10a.
In some embodiments, the capacitive sensor 60 may be a SAR sensor to sense a SAR (Specific Absorption Rate) value through the first radiator 40 and the second radiator 50. Taking the example that the capacitance sensor 60 detects the detection area 10a through the second radiator 50, if a finger is placed in the detection area 10a, an induced electromagnetic field is generated in a human body under the action of an external electromagnetic field, and since various organs of the human body are lossy media, the internal electromagnetic field generates current, so that electromagnetic energy is absorbed and dissipated. Thus, when there is a finger approach to the detection area 10a, the SAR value changes when there is no finger approach to the detection area 10a. Such a change in SAR value will be characterized as a change in capacitance of the capacitive sensor 60.
When the first capacitance value is smaller than the first threshold value, the capacitive sensor 60 obtains a second capacitance value through the second radiator 50. In this embodiment, the first threshold is set according to the capacitance value obtained by the capacitance sensor 60 when the electronic device 100 is placed on the metal table. Specifically, when the first capacitance value is greater than or equal to the first threshold value, it indicates that the electronic device 100 is placed on the metal mesa. Correspondingly, when the first capacitance value is smaller than the first threshold value, it indicates that the electronic device 100 is not placed on the metal table, at this time, the second capacitance value acquired by the capacitive sensor 60 through the second radiator 50 can accurately represent whether a finger or a foreign object exists in the detection area 10a, so that it is avoided that when the electronic device 100 is placed on the metal table, the metal table affects the second radiator 50, which results in that the second capacitance value cannot accurately reflect whether a finger or a foreign object exists in the detection area 10a, thereby causing a misjudgment and affecting the control accuracy of the controller 70 on the working state of the driving mechanism 30. For convenience of understanding, the electronic device 100 does not include the first radiator 40 as a comparative example for comparison, specifically, if the capacitive sensor 60 does not detect outside the detection region 10a through the first radiator 40 to determine whether the electronic device 100 is placed on a metal table, when the electronic device 100 is placed on the metal table, the second capacitance value obtained by the capacitive sensor 60 through the second radiator 50 exceeds the set value when a finger or a foreign object exists in the detection region 10a, at this time, the electronic device 100 is placed on the metal table and is erroneously determined as that the finger or the foreign object exists in the detection region 10a, so that when the electronic device 100 is furled on the metal table, the electronic device 100 cannot be furled normally due to the erroneous determination that the finger or the foreign object exists in the detection region 10a. It should be noted that this embodiment is only described for convenience of understanding, taking the electronic device 100 placed on a metal table as an example, and is not intended to limit the usage scenario of the electronic device 100 in the present application.
The controller 70 is electrically connected to the capacitive sensor 60. Specifically, the controller 70 is configured to: when the first capacitance is greater than or equal to the first threshold, the controller 70 controls the driving mechanism 30 to drive the second housing 14 to move toward the folded position relative to the first housing 12, and when the first capacitance is smaller than the first threshold and the second capacitance is greater than or equal to the second threshold, the controller 70 controls the driving mechanism 30 to drive the second housing 14 to move toward the unfolded position relative to the first housing 12 or controls the driving mechanism 30 to stop driving the second housing 14 to move relative to the first housing 12.
It should be noted that the first threshold and the second threshold may be set according to the capacitance value measured by the capacitive sensor 60 when the electronic device 100 is placed in an environment such as a metal platform or a finger is placed in the detection area 10a. By comparing the first capacitance value detected by the capacitance sensor 60 with the first threshold value, it is determined whether the electronic device 100 is placed on the metal platform. Accordingly, by comparing the second capacitance value detected by the capacitance sensor 60 with the second threshold value, it is determined whether or not the detection region 10a has a finger or a foreign object. Wherein, in the case that the electronic device 100 is placed on the metal platform, the controller 70 controls the driving mechanism 30 to drive the second housing 14 to move toward the folded position relative to the first housing 12. In a case where the electronic device 100 is not placed on the metal platform, the capacitive sensor 60 obtains a second capacitance value through the second radiator 50.
In some embodiments, the second capacitance value is greater than or equal to a second threshold value in the presence of a finger or foreign object at the detection zone 10a. The driving mechanism 30 will not 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 fingers being pinched and damaged, and also avoid the driving mechanism 30 from being damaged by a large reaction force.
In some embodiments, as shown in connection with fig. 6, the displacement of the second housing 14 from the expanded position to the intermediate position is a first displacement D1, and the displacement of the second housing 14 from the intermediate position to the collapsed position is a second displacement D2. The first displacement D1 is greater than the second displacement D2, so that the width of the detection region 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 capacitive sensor 60 obtains the second capacitance value through the second radiating body 50 during the process that the driving mechanism 30 drives the second housing 14 to move from the middle position to the folded position relative to the first housing 12, that is, the capacitive sensor 60 detects the second displacement D2 of the second housing 14 without detecting the detection area 10a during the first displacement D1 of the second housing 14, so as to reduce power consumption.
In some embodiments, the second displacement D2 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, which can ensure that the detection area 10a has sufficient detection width in the first direction, so as to avoid the finger being pinched and injured, the capacitance sensor 60 can detect the finger, and meanwhile, the detection area 10a can be prevented from having sufficient detection width in the first direction, which is too large, and causes unnecessary energy consumption waste.
In some embodiments, the controller 70 is electrically connected to an antenna switch and a radio frequency processing circuit, and the antenna switch is connected between the second radiator 50 and the radio frequency processing circuit and is used for switching the operating state of the second radiator 50. Specifically, when the second housing 14 is in the unfolded position, the antenna switch electrically connects the second radiator 50 to the radio frequency processing circuit, and the radio frequency processing circuit can transmit a radio frequency signal through the second radiator 50, so that the signal transmission efficiency of the electronic device 100 in the unfolded use process of the flexible screen 20 can be improved. When the second housing 14 is moved away from the extended position, the antenna switch electrically disconnects the second radiator 50 from the rf processing circuit, and specifically, the second radiator 50 and the rf processing circuit are in an electrical signal disconnection state, and the capacitance sensor 60 can stably sense the capacitance change in the detection area 10a through the second radiator 50. The antenna switch may be a switching element built into the electronic device 100 and controlled by the controller 70. In some embodiments, a user may perform on-off control on the antenna switch through a button of the electronic device 100, and then the user may turn on or off the function of the second radiator 50 for transmitting the radio frequency signal according to actual needs.
In some embodiments, the second radiator 50 may also be connected to the second casing 14 and fixed relative to the second sidewall 14a.
Referring again to fig. 2 and 4, the housing assembly 10 includes a plate 16, and when the second casing 14 is in the unfolded position, the plate 16 is at least partially exposed between the first sidewall 12a and the second sidewall 14a, so that the plate 16 is utilized to prevent the internal structure of the electronic device 100 from being exposed between the first sidewall 12a and the second sidewall 14a, and specifically, when the second casing 14 is in the unfolded position, the plate 16 can provide an external appearance surface of the electronic device 100 to maintain the external integrity of the electronic device 100. Understandably, when the second housing 14 is in the folded position, the plate 16 is hidden in the first housing 12 and the second housing 14, and at this time, the first housing 12 and the second housing 14 form an appearance surface of the electronic device 100.
The plate 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, the first housing 12 and the second housing 14 are slidably connected to the plate 16, so that the plate 16 can be used to provide stable support for sliding between the first housing 12 and the second housing 14.
With continued reference to fig. 2 and 4, the electronic device 100 is provided with a pulling element 80, the pulling element 80 is disposed at an end of the first housing 12 away from the second housing 14, and during the process of switching the second housing 14 from the folded position to the unfolded position relative to the first housing 12, the pulling element 80 may pull the flexible screen 20 to deform so that the 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 passes by the pulling member 80, and the pulling member 80 can limit the bending radius of the flexible screen 20 within a suitable range to avoid damage to the flexible screen 20 caused by an excessively small bending radius. Of course, the pulling member 80 can also avoid the thickness of the electronic device 100 caused by the bending radius of the flexible screen 20 being too large.
In some embodiments, the pulling member 80 may be a rotating shaft structure with convex teeth, and the flexible screen 20 is coupled with the pulling member 80 by meshing or the like. When second housing 14 slides relative to first housing 12, the portion of flexible screen 20 engaged with pulling member 80 is moved by pulling member 80 and is extracted from or retracted into housing assembly 10.
In other embodiments, the pulling member 80 is a circular shaft without additional teeth. During the switching of the second housing 14 from the collapsed position to the expanded position, the traction member 80 is used to spread apart the portion of the flexible screen 20 attached to the traction member 80, so that more of the flexible screen 20 is exposed outside the shell assembly 10 and remains flat. In this embodiment, the pulling member 80 may be rotatably disposed on the second housing 14, and during the gradual unfolding of the flexible screen 20, the pulling member 80 may rotate along with the movement of the flexible screen 20, so as to reduce the resistance to the flexible screen 20 during the unfolding process and reduce the wear of the contact portion between the pulling member 80 and the flexible screen 20.
In some embodiments, the traction element 80 may also be secured to the first housing 12, the traction element 80 having a smooth surface. The pulling member 80 is in slidable contact with the flexible screen 20 through its smooth surface during the process of unfolding the flexible screen 20. In other words, in such an embodiment, the pulling member 80 may be integrally formed with the first housing 12 or welded, the pulling member 80 may be considered as a part of the first housing 12, and the free end 204 of the flexible screen 20 passes around the end of the first housing 12 remote from the second housing 14 and extends into the housing assembly 10.
In embodiments in which the shell assembly 10 includes a board body 16, the board body 16 is provided with a second radiator 50, for example, as shown in connection with fig. 5 to 8, both the side 16a of the board body 16 facing away from the flexible screen 20 and the side 16b of the board body 16 facing towards the flexible screen 20 are provided with the second radiator 50. It should be noted that in some embodiments, only one of the side 16a of the board 16 facing away from the flexible screen 20 and the side 16b of the board 16 facing the flexible screen 20 is provided with the second radiator 50.
The second radiator 50 may be disposed at a position of the first case 12 overlapping the board 16, or may be disposed at a position of the second case 14 overlapping the board 16. Here, the overlapping position of two objects refers to an overlapping area of orthographic projections of the two objects at the detection area 10a.
As shown in fig. 7 and 8, 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 may be rubber, latex, EVA (Ethylene Vinyl Acetate), EPS (Expanded Polystyrene, polystyrene foam), or the like. With the good buffering performance of the buffering member 18, the electronic device 100 has good anti-falling performance as a whole when the second casing 14 is in the folded position. Specifically, since the buffer 18 is located between the first side wall 12a and the second side wall 14a, when the second casing 14 is located at the folded position, the buffer 18 can reduce the hard collision between the first side wall 12a and the second side wall 14a, so as to achieve a buffering effect.
In the embodiment where the first sidewall 12a is provided with the buffer 18, a side of the buffer 18 facing away from the first sidewall 12a may be provided with the second radiator 50. Accordingly, in the embodiment in which the second sidewall 14a is provided with the buffer 18, a side of the buffer 18 facing away from the second sidewall 14a may be provided with the second radiator 50.
The first radiator 40 and the second radiator 50 may be made of the same material, and in particular, in order to obtain a good detection effect, the first radiator 40 and the second radiator 50 are antennas. The second radiator 50 will be described as an example.
The second radiator 50 may be an FPC antenna, which is an antenna manufactured on a corresponding structural member by using an FPC process. Specifically, the FPC process is a printed circuit board having a pattern formed by using a flexible substrate, and is composed of an insulating substrate and a conductive layer, and an adhesive may be interposed between the insulating substrate and the conductive layer and attached to a portion where an antenna is to be disposed. The FPC antenna is light and thin, good in bending property and low in cost. In this embodiment, the FPC antenna may be disposed in the first housing 12 or the second housing 14, as long as it can be opposite to the detection area 10a and the capacitance sensor 60 can sense the SAR value of the detection area 10a by the second radiator 50.
In some embodiments, the second radiator 50 may be a PDS antenna, which is an antenna manufactured on a corresponding structural member by using a PDS process. Specifically, a conductive silver paste is applied to the surface of the structure such as the first sidewall 12a, the second sidewall 14a, the board body 16, or the bumper 18, and then the conductive three-dimensional circuit is formed by multi-layer printing of the silver paste, and then the final second radiator 50 is fabricated by heat curing. Because the PDS antenna can be directly printed with a circuit, special laser modified materials are not needed, and the cost can be reduced.
In the above embodiments, by the structural arrangement of the first radiator 40, the second radiator 50, the capacitive sensor 60, the controller 70, and the like of the electronic device 100 according to the present invention, the fingers of the user can be effectively prevented from being pinched by the first casing 12 and the second casing 14 moving relative to each other, and the probability of the electronic device 100 being placed on a metal table to misjudge the presence of the finger or the foreign object in the detection area 10a can be reduced, so that the flexible screen 20 is not necessary for the electronic device 100 to prevent pinching, that is, the flexible screen 20 can be omitted from the electronic device 100 according to some embodiments.
Based on the electronic device 100, another embodiment of the present application provides a control method for controlling the electronic device 100, which can effectively prevent a user from being pinched by fingers during using the electronic device 100.
Specifically, as shown in fig. 9, the control method includes the following steps:
step S102, receiving the control operation information, and controlling the driving mechanism 30 to drive the second housing 14 to move toward the closed position relative to the first housing 12 according to the 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 control operation information may be input to the electronic device 100 by a user clicking or sliding or dragging the operation interface of the flexible screen 20, or may be input by operating keys of the electronic device 100. In some applications, when the user slides the two fingers on the flexible screen 20 in a direction approaching each other, the driving mechanism 30 drives the second housing 14 to move toward the folded position relative to the first housing 12 to fold the flexible screen 20. In embodiments where the electronic device 100 does not include the flexible screen 20, the first operation control information may be a control command related to the movement of the second housing 14 toward the collapsed position relative to the first housing 12.
In step S104, during the driving mechanism 30 drives the second housing 14 to move to the closed position relative to the first housing 12, the capacitive sensor 60 of the electronic device 100 obtains a first capacitance value through the first radiator 40.
In some embodiments, after obtaining the first capacitance value, specifically, after step S104, by determining whether the first capacitance value is greater than the first threshold value, it can be determined whether the electronic device 100 is placed on a metal table for the electronic device 100 to perform a subsequent operation.
If the first capacitance is greater than or equal to the first threshold, step S106 is executed to control the driving mechanism 30 to drive the second housing 14 to move toward the closed position relative to the first housing 12.
When the first threshold is a capacitance value measured by the capacitance sensor 60 when the electronic device 100 is placed on a metal table, and the first capacitance value is greater than or equal to the first threshold, it indicates that the electronic device 100 is placed on the metal table, and at this time, the metal table does not affect the folding operation of the electronic device 100, and then the driving mechanism 30 continues to drive the second housing 14 to move toward the folded position relative to the first housing 12.
Otherwise, step S108 is executed, in which the capacitive sensor 60 obtains a second capacitance value through the second radiator 50 to obtain a second capacitance value.
If the finger of the user is close to the detection area 10a, the second capacitance of the capacitive sensor 60 is a first value, and if the finger of the user is not close to the detection area 10a, the second capacitance of the capacitive sensor 60 is a second value, and then the finger is close to the detection area 10a, the first value and the second value are different, and a second threshold value can be reasonably configured according to the first value and the second value, so as to determine whether the finger of the user is close to the detection area 10a according to the second capacitance detected by the capacitive sensor 60.
Specifically, after the second capacitance value is obtained, specifically, after step S108, by determining whether the second capacitance value is larger than the second threshold value, it is possible to specify whether the finger or the foreign object exists in the detection area 10a.
If the second capacitance is greater than or equal to the second threshold, step S110 is executed, and the driving mechanism 30 is controlled to drive the second housing 14 to move toward the extended position relative to the first housing 12 or the driving mechanism 30 is controlled to stop driving the second housing 14 to move relative to the first housing 12. Otherwise, step S106 is executed, in which the driving mechanism 30 is controlled to drive the second housing 14 to move toward the closed position relative to the first housing 12.
When there is a finger or a foreign object in the detection area 10a, the second capacitance is greater than or equal to the second threshold, and the driving mechanism 30 will not drive the second housing 14 to move toward the closed position relative to the first housing 12, so as to effectively reduce the probability of the finger being pinched by the user, and at the same time, prevent the driving mechanism 30 from being damaged due to a large reaction force.
In some embodiments, in the embodiment where the electronic device 100 includes the flexible screen 20, the controller 70 is electrically connected to the flexible screen 20, and can use the flexible screen 20 to prompt a user to notify the user that an abnormal folding process of the electronic device 100 occurs.
Specifically, the control method further comprises the steps of:
and if the second capacitance value is larger than or equal to the second threshold value, controlling the flexible screen 20 to display a reminding interface to remind the user that the abnormity exists in the detection area 10a.
Note that, the manner of alerting the user that the detection area 10a is abnormal may be a graphic or animation. For example, when a hand pinching abnormality occurs in the detection area 10a, the flexible screen 20 displays an image or animation in which a hand is pinched to vividly and vividly remind the user, and the prompting method is also interesting. In some embodiments, a text or a flashing display may be used to remind the user that there is an abnormality in the detection area 10a.
The acquisition timings of the first capacitance value and the second capacitance value may be synchronized or may be performed in steps. When the obtaining time of the first capacitance value and the second capacitance value is synchronous, the capacitance sensor 60 obtains the first capacitance value and the second capacitance value continuously or intermittently through the first radiator 40 and the second radiator 50 in the whole process of moving the second housing 14 to the closed position relative to the first housing 12, or in the process of moving the second housing 14 to the closed position from the middle position relative to the first housing 12.
In an embodiment where the first capacitance value and the second capacitance value are obtained step by step, the second capacitance value may be obtained after the first capacitance value is determined and a certain condition is satisfied. Exemplarily, when the first capacitance value is smaller than the first threshold value, the capacitive sensor 60 obtains the second capacitance value through the second radiator 50, and in this way, the capacitive sensor 60 does not need to continuously obtain the second capacitance value through the second radiator 50, thereby effectively saving power consumption and prolonging the service life of the capacitive sensor 60. It can be understood that, since it is indicated that the electronic device 100 is placed on the metal table when the first capacitance value is greater than or equal to the first threshold value, and accordingly, it is indicated that the electronic device 100 is not placed on the metal table when the first capacitance value is less than the first threshold value, in this embodiment, the acquisition timing of the second capacitance value may be regarded as determining that the electronic device 100 is not placed behind the metal table, thereby effectively eliminating interference of the electronic device 100 placed on the metal table on the detection area 10a, and avoiding misjudgment of the electronic device 100 placed on the metal table as the presence of a finger or a foreign object in the detection area 10a.
Whether the acquisition timings of the first capacitance value and the second capacitance value are synchronous is not limited herein. For ease of understanding, the following further provides a control method based on the control electronic device 100, specifically, as shown in fig. 10, the control method includes the following steps:
step S202, receiving the control operation information, and controlling the driving mechanism 30 to drive the second housing 14 to move toward the closed position relative to the first housing 12 according to the control operation information.
In step S204, during the process that the driving mechanism 30 drives the second housing 14 to move toward the closed position relative to the first housing 12, the capacitive sensor 60 of the electronic device 100 obtains a first capacitance value through the first radiator 40, and the capacitive sensor 60 obtains a second capacitance value through the second radiator 50 to obtain a second capacitance value.
And after the first capacitance value and the second capacitance value are obtained, performing condition judgment. Specifically, it is determined whether the condition: the first capacitance value is less than a first threshold value and the second capacitance value is greater than or equal to a second threshold value.
If the first capacitance value is smaller than the first threshold value and the second capacitance value is greater than or equal to the second threshold value, step S206 is executed to control the driving mechanism 30 to drive the second housing 14 to move toward the extended position relative to the first housing 12 or to control the driving mechanism 30 to stop driving the second housing 14 to move relative to the first housing 12. Otherwise, step S208 is executed to control the driving mechanism 30 to drive the second housing 14 to move toward the closed position relative to the first housing 12.
By the control method, when fingers or foreign matters exist in the detection area 10a, the driving mechanism 30 can continue to drive the second housing 14 to move towards the furled position relative to the first housing 12, so that the electronic device 100 is pinched or damaged, meanwhile, misjudgment caused by a metal environment outside the detection area 10a when detection is performed in the detection area 10a is avoided, so that the electronic device 100 cannot be furled normally, and the user experience of using the electronic device 100 is effectively improved.
All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
