As shown in FIGS. 1 to 4 , the present invention provides a foldable electronic device 10 . The foldable electronic device 10 includes a first casing 11 , a second casing 12 , an inner display screen 14 , an outer display screen 13 and a detection module. The first casing 11 and the second casing 12 are rotatably connected, so that the foldable electronic device 10 can assume a folded state or an unfolded state. The first casing 11 includes a first inner side 111 and a first outer side 112 arranged opposite to each other, and the second casing 12 includes a second inner side 121 and a second outer side 122 arranged opposite to each other. When the 10 is in the folded state, the first inner side 111 and the second inner side 121 are disposed facing each other, and the foldable electronic device 10 further includes a first intermediate state and a second intermediate state between the folded state and the unfolded state. The inner display screen 14 is located on the first inner side 111 and the second inner side 121 , the outer display screen 13 is located on the first outer side 11 of the first casing 11 , and the detection module is used to detect the first casing 11 and the second casing 12 . relative position. The foldable electronic device 10 includes a first preset relative position and a second preset relative position. When the foldable electronic device 10 is switched from the folded state to the first intermediate state, the inner display screen 14 is turned on and the outer display screen 13 is turned on. Turn off the screen; when the foldable electronic device 10 is switched from the unfolded state to the second intermediate state, the inner display screen 14 is turned off and the outer display screen 13 is turned on.

Specifically, the first housing 11 includes opposite inner edges 113 and outer edges 114 , the second housing 12 includes opposite inner edges 123 and outer edges 124 , the inner edges 113 of the first housing 11 and the second housing 12 The inner edges 123 of the two are connected with the rotating shaft 15, so that the first casing 11 and the second casing 12 are connected in rotation. The first casing 11 and the second casing 12 can rotate relative to each other between 0° and 180°. When the foldable electronic device 10 is in the folded state, the included angle θ between the first housing 11 and the second housing 12 is 0°; when the foldable electronic device 10 is in the unfolded state, the first housing 11 and the second housing 12 are in the unfolded state. The included angle θ between the two casings 12 is 180°. When the first casing 11 and the second casing 12 are turned back, the angle θ between the first casing 11 and the second casing 12 increases, and the foldable electronic device 10 is in the unfolding state. Switch from the folded state to the first intermediate state until the unfolded state; when the first shell 11 and the second shell 12 rotate toward each other, the angle θ between the first shell 11 and the second shell 12 decreases, and the The foldable electronic device 10 is in the process of being folded, and can be switched from the unfolded state to the second intermediate state until the folded state.

The foldable electronic device 10 has two display screens inside and outside. The inner display screen 14 is a flexible display screen and can be folded. The size of the inner display screen 14 is larger than the size of the outer display screen 13 . In this way, the user can switch between the inner and outer display screens according to the usage habits, which makes the use of the foldable electronic device 10 more convenient. For example, when the foldable electronic device 10 is in use, the foldable electronic device 10 is in an unfolded state, the inner display screen 14 is in use, and the outer display screen 13 is in an off state. When the external display screen 13 needs to be used, the foldable electronic device 10 is folded, the first casing 11 and the second casing 12 are rotated toward each other, and the unfolded state is switched to the second intermediate state. At this time, the detection module detects that the foldable electronic device 10 is in the process of folding, and the foldable electronic device 10 is in the second intermediate state, the inner display screen 14 is turned off, the outer display screen 13 is turned on, and then the first housing 11 And the second casing 12 can continue to rotate so that the foldable electronic device 10 is completely in a folded state, and the user can use the foldable electronic device 10 through the external display screen 13 .

When the inner display screen 14 is to be used, the foldable electronic device 10 is unfolded, and the first casing 11 and the second casing 12 are rotated back to switch from the folded state to the first intermediate state. At this time, the detection module detects that the foldable electronic device 10 is in the process of unfolding and is in the first intermediate state. At this time, the outer display screen 13 is turned off, the inner display screen 14 is turned on, and then the first casing 11 and the second casing 12 continue to rotate so that the foldable electronic device 10 is in a fully unfolded state. In this way, in the process of using the foldable electronic device 10, the switching between the outer display screen 13 and the inner display screen 14 can be automatically completed by unfolding the foldable electronic device 10, without the need for a user to perform corresponding operations.

The detection module can not only detect whether the first casing 11 and the second casing 12 are in the first preset relative position and the second preset relative position, but also detect the relative rotation of the first casing 11 and the second casing 12 The rotation direction at the time is used to judge whether the foldable electronic device 10 is in the unfolding process or the folding process. The relative position between the first shell 11 and the second shell 12 in the first intermediate state is the same as the relative position between the first shell 11 and the second shell 12 in the second intermediate state, namely The angle θ ₁ between the first casing 11 and the second casing 12 in the first intermediate state, and the angle θ ₂ between the first casing 11 and the second casing 12 in the second intermediate state are equal (θ ₁ =θ ₂ ). In other embodiments, the included angle θ ₁ and the included angle θ ₂ may not be equal. In the following descriptions, the included angle θ ₁ and the included angle θ ₂ are equal to each other. Among them, the included angle θ ₁ is greater than or equal to 30° and less than or equal to 45°, that is, 30°≤θ ₁ ≤45°; the included angle θ ₂ is greater than or equal to 30° and less than or equal to 45°, that is, 30°≤ θ ₂ ≤ 45°.

In one embodiment, the detection module includes an angle sensor 16 for detecting the angle between the first casing 11 and the second casing 12 . The first casing 11 and the second casing 12 are connected by a rotating shaft 15 , and the angle sensor 16 can be located on the rotating shaft 15 . The relative position between the first casing 11 and the second casing 12 is detected by providing the angle sensor 16 . When the first shell 11 and the second shell 12 are in the folding process, the angle between the first shell 11 and the second shell 12 becomes smaller; when the first shell 11 and the second shell 12 are in the unfolding process During the process, the angle between the first casing 11 and the second casing 12 becomes larger.

In one case, the angle sensor 16 can detect the angle between the first casing 11 and the second casing 12 during the entire folding and unfolding process of the foldable electronic device 10, so that the angle sensor 16 can detect the angle between the first casing 11 and the second casing 12. The rotation direction of the first casing 11 and the second casing 12 can be detected, and whether they are rotated to the first intermediate state, and then can be used to control the switching between the inner display screen 14 and the outer display screen 13 .

In another case, when the angle θ between the first casing 11 and the second casing 12 is ≤ θ ₁ , the angle sensor 16 can only detect the clamping angle between the first casing 11 and the second casing 12 horn. For example, during the unfolding process of the foldable electronic device 10, the angle between the first casing 11 and the second casing 12 increases from 0° to θ ₁ and then continues to increase to 180°, so that the foldable electronic device The device 10 is fully expanded (ie switched from the collapsed state to the expanded state). When the angle between the first casing 11 and the second casing 12 is θ≥0°, and _θ≤θ1 , the angle sensor 16 can detect the angle between the first casing 11 and the second casing 12 , at the same time, it can also be judged that the foldable electronic device 10 is in the unfolding process at this time, so that when the foldable electronic device 10 is rotated to the first intermediate state, the foldable electronic device 10 can control the inner display screen 14 to light up, and the outer display screen 13 to turn off, and the completion is completed. Switch between internal and external screens during expansion. During the folding process of the foldable electronic device 10, the angle between the first casing 11 and the second casing 12 decreases from 180° to θ ₁ and then continues to 0°, so that the foldable electronic device 10 is completely folded (that is, switching from the unfolded state to the folded state). When the angle θ between the first casing 11 and the second casing 12 is ≤ 180°, and θ > θ ₁ , the angle sensor 16 cannot detect the clamping angle between the first casing 11 and the second casing 12 until the angle between the first shell 11 and the second shell 12 is θ ₁ , then the angle sensor 16 can detect the angle between the first shell 11 and the second shell 12. It can be judged that the foldable electronic device 10 is in the folding process at this time and is in the first intermediate state, the foldable electronic device 10 can control the inner display screen 14 to turn off, and the outer display screen 13 to light up, completing the opening process of the inner and outer screens. switch. This can relatively reduce the power of the angle sensor 16 .

By detecting the relative position between the first casing 11 and the second casing 12 through the network, the rotation direction of the first casing 11 and the second casing 12 during relative rotation and whether they are in the first preset relative position can be obtained.

In one case, in one case, the distance sensor 17 can detect the relative position between the first housing 11 and the second housing 12 during the entire unfolding and folding process of the foldable electronic device 10, so that The distance sensor 17 can detect the rotation direction of the first casing 11 and the second casing 12 and whether they are rotated until the first intermediate state, and then can be used to control the switching between the inner display screen 14 and the outer display screen 13 .

In another case, the distance sensor 17 can detect the distance between the first casing 11 and the second casing 12 only when the angle θ between the first casing 11 and the second casing 12 is ≤ θ ₁ . For example, when the foldable electronic device 10 is in the unfolding process, the angle between the first casing 11 and the second casing 12 increases from 0° to θ ₁ and then continues to increase to 180°, so that the foldable electronic device 10 is expanded. The electronic device 10 is fully unfolded (ie, switched from the folded state to the unfolded state). When the angle between the first casing 11 and the second casing 12 θ≥0°, and _θ≤θ1 , the distance sensor 17 can detect the distance between the first casing 11 and the second casing 12 Increase, it is judged that the foldable electronic device 10 is in the unfolding process at this time, so that when the foldable electronic device 10 is rotated to the first intermediate state, the foldable electronic device 10 can control the inner display screen 14 to light up and the outer display screen 13 to turn off, and the unfolding process is completed. Switch between internal and external screens. During the folding process of the foldable electronic device 10, the angle between the first casing 11 and the second casing 12 decreases from 180° to _θ1 and then continues to 0°, so that the foldable electronic device 10 is completely folded (that is, switching from the unfolded state to the folded state). When the included angle θ between the first casing 11 and the second casing 12 is θ≤180°, and θ> _θ1 , the distance sensor 17 cannot detect the relative relationship between the first casing 11 and the second casing 12 until the angle between the first shell 11 and the second shell 12 is at time θ ₁ , at which time the distance sensor 17 can detect that the relative distance between the first shell 11 and the second shell 12 decreases. At this time, it can be judged that the foldable electronic device 10 is in the process of folding, so when the foldable electronic device 10 is rotated to the first intermediate state, the foldable electronic device 10 can control the inner display screen 14 to turn off and the outer display screen 13 to light up. Complete the internal and external screen switching during the folding process. This can relatively reduce the power of the distance sensor 17 .

The transmitting end 171 is located on the inner side of the first casing 11 , and the receiving end 172 is located on the inner side of the second casing 12 . The transmitting end 171 is located at the inner edge 113 of the first casing 11 , and the receiving end 172 is located at the inner edge 123 of the second casing 12 . In this way, the transmitting end 171 and the receiving end 172 can be brought closer, the power of the distance sensor 17 can be reduced, and the user's hand can be effectively avoided during the opening and closing of the foldable electronic device 10 .

The invention also provides a control method of the display screen. The specific process is as follows: in the process of switching between the unfolded state and the folded state, the relative position between the first housing 11 and the second housing 12 of the foldable electronic device 10 is detected. When the foldable electronic device 10 is switched from the folded state to the first intermediate state, the inner display screen 14 is turned on, and the outer display screen 13 is turned off. When the foldable electronic device 10 is switched from the unfolded state to the second intermediate state, the inner display screen 14 is turned off, and the outer display screen 13 is turned on. The detection module can not only detect whether the first casing 11 and the second casing 12 are in the first preset relative position and the second preset relative position, but also detect the relative rotation of the first casing 11 and the second casing 12. The rotation direction is used to determine whether the foldable electronic device 10 is in the process of opening or in the process of closing. Through the above method, when the foldable electronic device 10 is closed and opened, the switching of the inner and outer screens can be automatically completed, so that the use of the foldable electronic device is more convenient.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described.
