It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 6, fig. 1 is a first schematic structural diagram of an electronic device according to an embodiment of the present disclosure, fig. 2 is a second schematic structural diagram of the electronic device according to the embodiment of the present disclosure, fig. 3 is a schematic cross-sectional structural diagram of the electronic device shown in fig. 2 along a direction P1-P1, fig. 4 is a third schematic structural diagram of the electronic device according to the embodiment of the present disclosure, fig. 5 is a fourth schematic structural diagram of the electronic device according to the embodiment of the present disclosure, and fig. 6 is a schematic cross-sectional structural diagram of the electronic device shown in fig. 5 along a direction P2-P2. The electronic device 20 may include a first housing 100, a second housing 200, and a flexible screen assembly 300. The first and

second housings

100 and 200 are relatively movable in directions toward and away from each other, so that switching between the expanded state and the collapsed state can be achieved. In this regard, the closed state can refer to fig. 1 to 3, that is, the state in which the first casing 100 and the second casing 200 are relatively moved in the direction of approaching each other and finally formed. In this regard, the unfolded state may refer to fig. 4 to 6, that is, a state in which the first casing 100 and the second casing 200 are relatively moved in a direction away from each other.

It is understood that the first housing 100 and the second housing 200 may perform relative movement to achieve lateral stretching of the electronic device 20. Wherein, the lateral drawing refers to a manner of drawing in a direction parallel to the display direction of the flexible screen assembly 300. So, can freely adjust the size of the screen display region of electronic equipment 20, can expand electronic equipment 20's display part and improve user's operation experience when needs use the large screen, simultaneously, when need not use the large screen, can not expand display part to make the complete machine size less, conveniently carry.

It should be noted that the unfolded state of the first casing 100 and the second casing 200 may be various, such as that the maximum moving distance of the first casing 100 and the second casing 200 in the direction away from each other is H, and the first casing 100 and the second casing 200 may move away from each other in the folded state to achieve the unfolded state with different distances formed by equal distances of one quarter H, one half H, and three quarters H. The state of the distance gradually becoming farther may be defined as a first developed state, a second developed state, a third developed state, and the like in this order.

It should be noted that when the first casing 100 and the second casing 200 are in the first unfolded state, such as the distance of the relative moving away of the first casing 100 and the second casing 200 in the first unfolded state is a quarter H, the first casing 100 and the second casing 200 can still perform the relative moving away to reach the second unfolded state, such as the distance of the relative moving away of the first casing 100 and the second casing 200 in the second unfolded state is a half H.

It is to be understood that the one or more unfolded states of the first and

second housings

100 and 200 according to the embodiment of the present application are only examples, and do not limit the unfolded states of the first and

second housings

100 and 200 according to the embodiment of the present application.

One end of the flexible screen assembly 300 is connected to the first casing 100, the other end of the flexible screen assembly 300 is wound around the end of the second casing 200 far away from the first casing 100, and the flexible screen assembly 300 is configured to move along with the relative movement of the first casing 100 and the second casing 200, so that a part of the flexible screen assembly 300 extends out of the electronic device 20 or retracts into the electronic device 20.

It is understood that the electronic device 20 may include opposing first and second sides, wherein the first side may be a front side of the electronic device 20 and the second side may be a back side of the electronic device 20. The first housing 100 and the second housing 200 can drive the flexible screen assembly 300 to move together or drive the flexible screen assembly 300 to move during the relative movement, so that the length of the flexible screen assembly 300 can be adjusted, and the size of the display area of the electronic device can be changed. When the first casing 100 and the second casing 200 are in the folded state, a part of the flexible screen assembly 300 is directly exposed outside the electronic device 20, and a part of the flexible screen assembly 300 is received inside the electronic device 20; or a portion of the flexible screen assembly 300, is located on a first side of the electronic device 20 and a portion of the flexible screen assembly 300 is located on a second side of the electronic device 20, i.e., the flexible screen assembly 300 is located on both the front and back sides of the electronic device 20 in the collapsed state. When the first casing 100 and the second casing 200 are relatively moved from the folded state to be unfolded, the portion of the flexible screen assembly 200 originally housed inside the electronic device 20 may gradually move to the outside of the electronic device 20, and finally, the portion of the flexible screen assembly 300 originally housed inside the electronic device 20 is exposed outside the electronic device 20, and may display a picture together with the portion of the flexible screen assembly 300 originally exposed outside the electronic device 20.

Referring to fig. 7 to 9, fig. 7 is an exploded view of the electronic device shown in fig. 4, fig. 8 is a first partial view of the electronic device shown in fig. 4, and fig. 9 is a second partial view of the electronic device shown in fig. 4. The first casing 100 and the second casing 200 are used to form an outer contour of the electronic device 20, the first casing 100 may be a regular shape, such as a rectangular parallelepiped structure or a rounded rectangular structure, and the first casing 100 may also be an irregular shape. The first housing 100 may be formed from plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The first housing 100 may be integrally formed such that the first housing 100 may be machined or molded as a single structure, or may be formed using a combination of structures (e.g., an inner frame structure forming one or more structures of an outer shell surface, etc.).

The first casing 100 may include a middle frame 110 and a first side frame 120, the middle frame 110 may serve as a carrier for other components of the electronic device 20, for example, the middle frame 110 may carry a driving device 500 of the electronic device 20, and the driving device 500 may be disposed at a position substantially in the middle of the substrate. The first bezel 120 surrounds the edge of the middle frame 110, and can cover the edge of the middle frame 110 to maintain the aesthetic appearance of the electronic device 20. The driving device 500 may drive the first casing 100 and the second casing 200 to move relatively to realize the engagement and disengagement of the first casing 100 and the second casing 200.

For example, the first casing 100 may be fixed, and the driving device 500 may drive the second casing 200 to move in a direction away from the first casing 100, so that a portion of the second casing 200 protrudes from the inside of the electronic device 20 to achieve separation between the first casing 100 and the second casing 200. The driving device 500 may also drive the second casing 200 to move towards the direction close to the first casing 100 together, so that a part of the second casing 200 enters the inside of the electronic device 20 and is received in the inside of the electronic device 20 to realize the fitting between the first casing 100 and the second casing 200. It is understood that the first housing 100 and the second housing 200 may reciprocate in a direction parallel to the first housing 100 or the second housing 200, thereby achieving separation and engagement between the first housing 100 and the second housing 200.

In the above embodiment, alternatively, the second housing 200 may be fixed, and the driving device 500 jointly drives the first housing 100 to reciprocate along the direction parallel to the second housing 200. Or the driving device 500 may also drive the first casing 100 and the second casing 200 to move simultaneously to achieve the engagement and disengagement of the first casing 100 and the second casing 200.

For example, the first frame 120 may include a first side 122, a second side 124 and a third side 126, the first side 122, the second side 124 and the third side 126 are sequentially connected, the first side 122 is disposed opposite to the second side 124 in a direction substantially perpendicular to the relative movement direction of the first casing 100 and the second casing 200, and the third side 126 is connected between ends of the same side of the first side 122 and the second side 124. It is understood that the first side 122 is located at the top of the electronic device 20, the second side 124 is located at the bottom of the electronic device 20, and the third side 126 is located at a side member of a side of the electronic device 20.

The second housing 200 may include a bracket 210 and a second frame 220, the bracket 210 may be slidably connected to the middle frame 110 of the first housing, and the bracket 210 is connected to a driving device 500, and the driving device 500 may drive the bracket 210 to reciprocate in a direction substantially parallel to the first housing 100 to realize the relative movement of the first housing 100 and the second housing 200.

The second bezel 220 may include a plurality of side members, for example, the second bezel 220 may include a first side member 222, a second side member 224 and a third side member 226, the first side member 222, the second side member 224 and the third side member 226 are sequentially connected, the first side member 222 is disposed opposite to the second side member 224 in a direction substantially perpendicular to a relative movement direction of the first casing 100 and the second casing 200, the first side member 222 is disposed opposite to the first side edge 122 in the relative movement direction of the first casing 100 and the second casing 200, and the second side member 224 is disposed opposite to the second side edge 124 in the relative movement direction of the first casing 100 and the second casing 200. The third side member 226 is connected between ends of the same sides of the first and

second side members

222 and 224 and is disposed opposite the third side edge 126 in the direction of relative movement of the first and

second housings

100 and 200.

It is understood that the first side member 222 is located at the top of the electronic device 20, and may form a top frame of the electronic device 20 together with the first side edge 110; the second side member 224 is positioned at the bottom of the electronic device 20 and may form a bottom bezel of the electronic device 20 together with the second side 124, and the third side member 226 is positioned at a side member at the other side of the electronic device 20.

When the first casing 100 and the second casing 200 are folded by relatively moving toward the direction of approaching each other, the end of the first side edge 122 close to the first side edge 222 abuts against the end of the first side edge 222 close to the first side edge 122, and the end of the second side edge 124 close to the second side edge 224 abuts against the end of the second side edge 224 close to the second side edge 124, as shown in fig. 1; when the first casing 100 and the second casing 200 are expanded by relatively moving from the collapsed state in a direction away from each other, an end portion of the first side edge 122 close to the first side edge 222 and an end portion of the first side edge 222 close to the first side edge 122 change from relative abutment to gradual separation, and an end portion of the second side edge 124 close to the second side edge 224 and an end portion of the second side edge 224 close to the second side edge 124 change from relative abutment to gradual separation, as shown in fig. 4.

In practical applications, when an obstacle (such as a finger of a user, another soft object, or a rigid object) exists between the first side 122 and the first side member 222, and/or an obstacle (such as a finger of a user, another soft object, or a rigid object) exists between the second side 224 and the second side member 224 during the relative movement of the first casing 100 and the second casing 200, if the two casings are forcibly moved, damage to the first casing 100, the second casing 200, and/or the driving device 500 may occur.

From the practical application point of view, by providing at least one detection device 400, the detection device 400 may be configured to detect whether an obstacle that obstructs the folding of the first casing 100 and the second casing 200 exists between the first casing 100 and the second casing 200 during the relative movement of the first casing 100 and the second casing 200. If the detection device 400 detects an obstacle, the detection result can be fed back to the driving device 500, and after receiving the detection result, the driving device 500 can stop driving the first casing 100 and the second casing 200 to move relatively, so that the driving device 500 can be prevented from continuously driving the two casings to move relatively under the condition that the obstacle exists, and the damage can be avoided.

The detection apparatus 400 may also feed back the detection result to other devices of the electronic device, such as a processor, and the processor may issue a prompt after receiving the detection result, such as an audible alarm, a pop-up window, a vibration alarm, and the like, to prompt the user that an obstacle exists. The user may remove the obstruction upon receiving the alert. The detection device 400 can perform real-time detection, and when it is detected that the obstacle is removed, the driving device 500 can be prompted to continue driving the two shells to move relatively.

With continued reference to fig. 7 to 9, the at least one detecting device 400 may include a first detecting device 420 and a second detecting device 440, the first detecting device 420 is disposed on the first side 122, and the first detecting device 420 is configured to detect whether there is an obstacle between an end of the first side 122 and an end of the first side 222 during the relative movement of the first casing 100 and the second casing 200. For example, the first side 122 may have an inner surface that is not visible from the outside of the electronic device 20 and an outer surface that is visible from the outside of the electronic device 20, and the first detecting device 420 is disposed on the inner surface of the first side 122. The second detecting means 440 is disposed on the second side 122, and the first detecting means 420 is used for detecting whether there is an obstacle between an end of the second side 124 and an end of the second side member 224 during the relative movement of the first casing 100 and the second casing 200, for example, the second side 124 may have an inner surface and an outer surface, the inner surface is a surface invisible from the outside of the electronic device 20, the outer surface is a surface visible from the outside of the electronic device 20, and the first detecting means 420 is disposed on the inner surface of the second side 124.

The first detecting device 420 may include a plurality of components, one or more components of the first detecting device 420 may be disposed on the first frame 120, and one or more components of the first detecting device 420 may be disposed on the second frame 140. For example, the first detecting device 420 may include a first detecting member and a second detecting member, the first detecting member may be a detector 422, the second detecting member may be a reflector 424, the detector 422 and the reflector 424 are oppositely disposed in the relative movement direction of the first casing 100 and the second casing 200, the detector 422 may be disposed on the first side 122, the reflector 424 may be disposed on the first side 222, the detector 422 may emit a detection signal (an optical signal such as an infrared light signal, a red light signal, a green light signal, or a blue light signal, or an ultrasonic signal, or other signals), the reflector 424 may receive and reflect the detection signal emitted by the detector 422 to form a reflection signal, and the detector 422 may receive the reflection signal.

When there is no obstacle between the end of the first side edge 122 and the end of the first side member 221, the detector 422 may normally receive the reflected signal reflected by the reflector 424; when there is an obstruction between the end of the first side edge 122 and the end of the first side member 221, the reflected signal is not received by the detector 422 because the obstruction blocks the transmission of the reflected signal. Based on this, the detector may determine that an obstacle is present and instruct the driving device 500 to stop driving when the reflected signal is not received.

In order to allow the detector 422 to distinguish between the effective reflected signal and the reflected radiation signal in the background environment, thereby providing a large detection range with good effect, the detector 422 can avoid misjudging the reflected signal reflected by the non-reflector 424 as the signal reflected by the reflector 424. The detection apparatus of the embodiment of the present application may further include a frequency detector (not shown in the figure), the detector 422 is configured to emit an optical signal in a preset frequency range, the reflector may reflect the optical signal to form a reflected optical signal, the frequency detector may detect a frequency of the reflected optical signal received by the detector 422, and when the frequency of the reflected optical signal detected by the frequency detector falls within the preset frequency range, it may be determined that the reflected optical signal received by the detector 422 is the reflected optical signal formed by reflection of the reflector 424, and is not a reflected radiation signal in the background environment or a reflected signal of another object. The detector 422 may determine that no obstruction is present after determining that the received reflected light signal is a reflected signal formed by reflection by the reflector 424.

The detector 422 may have a frequency modulation circuit (not shown), which may modulate the original detection signal emitted by the detector 422, so that the original detection signal is modulated into a modulated optical signal with a predetermined frequency range. The frequency modulation circuit can also suppress the noise inherent in each link of the first detection device 420 and the interference of external electromagnetic field, so that the first detection device 420 has higher detection capability.

The first detection device 420 of the embodiment of the present application may also be configured to start detection when the relative distance between the first casing 100 and the second casing 200 is less than or equal to a preset value, so as to prevent a hand or other object from being clamped by the two casings. It can be understood that the first detecting device 420 starts the detecting operation when the two housings are folded to a smaller distance, so as to avoid the situation that the first detecting device 420 is in the detecting state all the time and consumes a lot of power.

In other embodiments, a preset time may be set, and when the detector 422 does not receive the reflection signal reflected by the reflector 424 beyond the preset time, the driving device 500 is instructed to stop driving.

In the embodiment of the present application, the first detecting device 400 may be a photoelectric switch, and specifically, the first detecting device 400 may be a diffuse reflection photoelectric switch, which is a short for diffuse reflection photoelectric proximity switch, and detects whether there is an obstacle by using diffuse reflection of a detected object to a light beam and gating a circuit by a synchronous loop.

In other embodiments, the first detecting device 420 may further include a pressure sensor (not shown), and the pressure sensor may be disposed on a portion of the edge corresponding to the first frame 120. For example, the middle frame 110 may have a first edge 112 and a second edge 114, the first edge 112 and the second edge 114 are oppositely disposed in the relative movement direction of the first casing 100 and the second casing 200, the first edge 112 is disposed adjacent to the first side edge 122, and the second edge 114 is disposed adjacent to the second side edge 114. A piezoelectric sensor may be disposed on the first edge 112 and a pressure sensor may detect a pressure value acting on the first edge 112. The driving device 500 may stop driving the first housing 100 and the second housing 120 to move relatively when the detector 420 does not detect the reflection signal and/or the pressure value detected by the pressure sensor is greater than the threshold value. It is understood that the pressure sensor may be used in combination with the detector 420 to improve the detection accuracy of the first detection device 400.

With continued reference to fig. 7-9, the second detection device 440 may include multiple components, one or more components of the first detection device 420 may be disposed on the first frame 120, and one or more components of the second detection device 440 may be disposed on the second frame 140. The second detecting device 440 has the same structure as the first detecting device 420, and may also include a detector 442 and a reflector 444, wherein the detector 442 may be disposed on the second side edge 124, and the reflector 444 may be disposed on the second side edge. The detailed descriptions of the detector 442 and the reflector 444 can be found in the description of the detector 422 and the reflector 424 in the above embodiments, and are not repeated herein.

The second detecting means 440 may further comprise a pressure sensor (not shown in the figure), which may be arranged at the second edge 114, which may detect the force acting on the second edge 114, which may cooperate with the detector 442 and the reflector 444 for obstacle detection to improve the detection accuracy of the second detecting means 440.

The arrangement of the detection devices is not limited to this, and all of the detection devices 420 may be arranged on the first frame 120 or the second frame 140. For example, a part of the first bezel 120 or the second bezel 140 may be directly used as a reflection member, or a part of the first bezel 120 or the second bezel 140 may be specially processed to have a function of reflecting a predetermined detection signal. The detecting device 420 may emit a predetermined detecting signal, and when the predetermined detecting signal is transmitted to the first frame 120 or the second frame 140, the first frame 120 or the second frame 140 may reflect the predetermined detecting signal to the detecting device 420.

The driving device 500 may include a driving assembly 520 and a transmission assembly 540, wherein the driving assembly 520 is used for driving the transmission assembly 540 to move the second housing 200.

The driving assembly 520 may include a driving motor 522 and a speed reducer 524, wherein an output shaft of the driving motor 522 is in transmission connection with the speed reducer 524, for example, the driving motor 522 may be coaxially connected with the speed reducer 524, and the speed reducer 524 may reduce the speed of the driving motor 522 to increase the torque. The reduction member 524 may be a reduction gear box, or a reduction gear (such as a planetary gear set arrangement or a multi-stage reduction gear set arrangement). For example, the speed reducer 524 of the embodiment of the present application may be a planetary gear set, which may include a sun gear 5242, a plurality of planet gears 5244, an inner ring gear 5246 and a planet carrier 5248, the sun gear 5242 serving as a driving member may be connected to a driving shaft of the driving motor 522, and the driving motor 522 may drive the sun gear 5242 to rotate via the driving shaft.
