Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. 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.
The embodiment of the application provides electronic equipment. The electronic device will be described in detail below. The electronic device may be a computer, monitor, tablet, cellular telephone, media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a hanging device, a headset or earpiece device, a device embedded in eyeglasses or other device worn on the user's head, or other wearable or miniature device), a television, a computer display, a gaming device, an Augmented Reality (AR) device, a navigation device, or the like.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application, fig. 2 is a schematic diagram of a flexible display screen in an extended state in the electronic device according to the embodiment of the present application. In the exemplary configuration of fig. 1 and 2, the electronic device 100 is a portable device, such as a smartphone, media player, or tablet computer.
The electronic device 100 may include, among other things, a housing 120 and a flexible display screen 140. A receiving cavity (not shown) is formed in the housing 120, the flexible display screen 140 can be installed in the receiving cavity of the housing 120, and the flexible display screen 140 can be used for displaying images.
The flexible display screen 140 may be made of a flexible material, and the flexible display screen 140 may be deformed. Such as: the flexible display screen 140 may be bent, curved, etc. The flexible display screen 140 may be housed within the housing 120. A flexible display screen 140 cover layer, such as a flexible transparent glass layer, a flexible light-transmissive plastic, a flexible sapphire, or other flexible transparent layer, may be used to protect the flexible display screen 140.
In some embodiments, when the flexible display 140 is received within the housing 120, the flexible display 140 may be displayed through a light transmissive region on the housing 120, such as the light transmissive region 1262. For example: a portion of the flexible display 140 is positioned in the light-transmissive region 1262, and the flexible display 140 may be adjacent to the side of the housing 120 in the light-transmissive region 1262 or may be remote from the side of the housing 120 in the light-transmissive region 1262. When the flexible display panel 140 is housed in the housing 120, the flexible display panel 140 may not be displayed, and another display panel may be provided at the position of the light-transmitting region 1262 to display.
As shown in fig. 2, the flexible display screen 140 may extend from the inside of the housing 120, and the flexible display screen 140 may extend out of the housing 120 for displaying. The flexible display screen 140 may be moved outside the electronic device 100 for display. An opening 1266 may be formed in the housing 120, the opening 1266 may be formed at a periphery of the housing 120, the opening communicates a receiving cavity in the housing 120 with an outside of the housing 120, and the flexible display screen 140 may move to the outside of the electronic device 100 through the opening 1266.
Referring to fig. 3 and fig. 4, fig. 3 is another schematic structural diagram of an electronic device according to an embodiment of the present application, and fig. 4 is a cross-sectional view of the electronic device in fig. 3 along a direction X1-X1. The electronic device 100 further includes a driving assembly 160, the driving assembly 160 is disposed in the receiving cavity 122 of the housing 120, and the driving assembly 160 includes a roller 162 located in the receiving cavity 122 and a traction wheel 164 adjacent to the opening 1266. One end of the flexible display screen 140 is fixedly connected to the roller 162, and the flexible display screen 140 can be wound on the roller 162 by the rotation of the roller 162 to be received in the receiving cavity 122. The flexible display screen 140 is disposed on the traction wheel 164, and the flexible display screen 140 can be extended out of the housing 120 through the opening by rotating the traction wheel 164.
The flexible display screen 140 is rolled back into the housing 120 from outside the housing 120 by the roller 162, and the flexible display screen 140 can be conveniently rolled into the housing 120. If the roller 162 pushes out the flexible display screen 140, the flexible display screen 140 will be spread out, increasing the internal friction force, and easily causing the self-locking phenomenon, so that the flexible display screen 140 is difficult to be pushed out smoothly by the rotation of the roller 162 alone. It is reasonable to say that it is easy to pull the tape from the position of the tape extension, as we need to open it, but it is laborious to come out if one wants to rotate the central shaft. The flexible display screen 140 extends out of the shell 120 from the shell 120 and drives the flexible display screen 140 to move from the opening through the traction wheel 164 arranged at the adjacent opening, so that the flexible display screen 140 is conveniently moved out of the shell 120, and the phenomenon of self-locking caused by the fact that the flexible display screen 140 is diverged to increase the internal friction force is not easy to occur. It should be noted that the wheel center of the roller 162 may be the center of the housing 120, and if the housing 120 is cylindrical, the wheel center of the roller 162 is located on the axis of the housing 120. If the housing 120 is in other cylindrical shapes and the housing 120 also has an axis, the center of the roller 162 is located on or adjacent to the axis of the housing 120. The wheel center of the traction wheel 164 is also adjacent the opening.
The roller 162 may be a hollow roller 162, and a gap between an outer surface of the roller 162 and an inner surface of the housing 120 is slightly larger than a thickness of the flexible display screen 140 after being wound, so as to accommodate the flexible display screen 140. The circuit board, the battery, the antenna radiator, and the like of the electronic device 100 may be disposed inside the hollow roller 162. The drive assembly 160 may also be partially disposed within the hollow roller 162. The display back 144 of the flexible display screen 140 is disposed on the traction wheel 164, and the traction wheel 164 rotates to drive the flexible display screen 140 to move.
In some embodiments, the flexible display screen 140 may be displayed around the outer peripheral surface of the housing 120 or may extend from within the housing 120 to be extended for display.
Referring to fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of an electronic device according to an embodiment of the present application, and fig. 6 is a cross-sectional view of the electronic device in fig. 5 in a direction X2-X2. The drive assembly includes a first drive mechanism 166 and a second drive mechanism 168, the first drive mechanism 166 driving the roller 162 to rotate and the second drive mechanism 168 driving the traction wheel 164 to rotate.
A first drive mechanism 166 drives the roller 162 and a second drive mechanism 168 drives the traction wheel 164, both drive mechanisms driving the roller 162 and traction wheel 164, respectively. For example, one motor 161 drives the roller 162 via a first drive mechanism 166166, and the other motor 161 drives the traction wheel 164 via a second drive mechanism 168. Wherein the first driving mechanism 166 is centrally located within the housing 120 for facilitating driving of the roller 162, and the second driving mechanism 168 is disposed adjacent to the opening of the traction wheel 164 for facilitating driving of the traction wheel 164.
In other embodiments, the drive assembly 160 includes a motor 161, a gear box 163, a first drive mechanism 166, and a second drive mechanism 168, the motor 161 driving the first drive mechanism 166 and the second drive mechanism 168 through the gear box 163;
when the motor 161 rotates forwards, the motor 161 drives the first driving mechanism 166 to rotate through the gear box 163, and when the motor 161 rotates backwards, the motor 161 drives the second driving mechanism 168 to rotate through the gear box 163;
or when the motor 161 rotates reversely, the motor 161 drives the first driving mechanism 166 to rotate through the gear box 163, and when the motor 161 rotates forwardly, the motor 161 drives the second driving mechanism 168 to rotate through the gear box 163.
The first drive mechanism 166 and the second mechanism may be driven by one motor 161, respectively. Specifically, one of the motors 161 can be driven when the motor is rotated forward, and the other motor 161 can be driven when the motor is rotated backward, so that the space in the housing 120 can be effectively reduced, the size of the electronic device 100 can be reduced, and the space utilization rate in the housing 120 can be improved.
Specifically, when the motor 161 rotates forward, the motor 161 drives the first driving mechanism 166 to rotate the roller 162 through the gear box 163, and the second driving mechanism 168 idles (i.e., does not drive the traction wheel 164 to rotate); when the motor 161 rotates reversely, the motor 161 drives the second driving mechanism 168 to rotate the traction wheel 164 through the gear box 163, and the first driving mechanism 166 idles (i.e., does not drive the roller 162 to rotate).
In other cases, when the motor 161 rotates reversely, the motor 161 drives the first driving mechanism 166 to rotate the roller 162 through the gear box 163, and the second driving mechanism 168 idles (i.e., does not drive the traction wheel 164 to rotate); when the motor 161 rotates forward, the motor 161 drives the second driving mechanism 168 to rotate the traction wheel 164 through the gear box 163, and the first driving mechanism 166 idles (i.e., does not drive the roller 162 to rotate).
It will also be appreciated that the motor 161 may be selected to rotate the roller 162 in a forward direction to drive the traction wheel 164 in a reverse direction, or the motor 161 may be selected to rotate the roller 162 in a forward direction to drive the traction wheel 164 in a reverse direction, as desired.
Referring to fig. 7, fig. 7 is a schematic partial structural diagram of a driving mechanism of an electronic device according to an embodiment of the present disclosure. The wheel center of the roller 162 is located at a central position in the housing 120, the first driving mechanism 166 includes a first flywheel structure 167, the gear box 163 includes a first driving shaft (not shown) connected to the first flywheel structure 167, and when the first driving shaft drives the first flywheel structure 167 to rotate, the first flywheel structure 167 drives the roller 162 to rotate.
The wheel center of the roller 162 is located at the center position in the housing 120, so that the flexible display screen 140 can be conveniently wound on the roller 162 in a labor-saving manner, and the flexible display screen 140 can be wound in the housing 120. The first flywheel structure 167 of the first drive mechanism 166 may cause the roller 162 to rotate only when the motor 161 is rotating in either the forward or reverse direction.
The second driving mechanism 168 may include a second flywheel structure 169, a first pulley 1682, a second pulley 1684, and a transmission shaft 1686, the second pulley 1684 being coupled to the traction wheel 164 via the transmission shaft 1686, and the gear box 163 including a second driving shaft 1634 coupled to the second flywheel structure 169.
When the second driving shaft 1634 drives the second flywheel to rotate, the second flywheel drives the first pulley 1682 to rotate, the first pulley 1682 drives the second pulley 1684 to rotate through the belt 1683, and the second pulley 1684 drives the traction wheel 164 through the transmission shaft 1686.
The second freewheel structure 169 of the second drive mechanism 168 may cause the traction wheel 164 to rotate only when the motor 161 is rotating in either the reverse or forward direction, as opposed to the first freewheel structure 167. The first flywheel structure 167 and the second flywheel structure 169 rotate one of the roller 162 or the traction wheel 164 when the motor 161 rotates forward, and rotate the other of the roller 162 or the traction wheel 164 when the motor 161 rotates backward, so that the roller 162 and the traction wheel 164 are driven by the motor 161 respectively. In addition, since the wheel center of the roller 162 is located at the center of the housing 120, the corresponding motor 161, the first driving mechanism 166, the second driving mechanism 168, the gear box 163 and the like are correspondingly disposed at the center of the housing 120, and the traction wheel 164 needs to be disposed at an adjacent opening position, it is necessary to transmit the power of the second driving mechanism 168 located at the center of the housing 120 to the traction wheel 164 at the adjacent opening position through the first pulley 1682, the belt and the second pulley 1684, wherein the second pulley 1684 is connected with the traction wheel 164 through the transmission shaft 1686. For example, the center of the second pulley 1684 is fixedly connected to the transmission shaft 1686, and the other position of the transmission shaft 1686 is fixedly connected to the center of the traction wheel 164.
The first and second drive shafts 1634 are located on opposite sides of the gear box 163, i.e., the first drive shaft on one side of the gear box 163 is connected to the first flywheel structure 167 and the second drive shaft 1634 on the other side of the gear box 163 is connected to the second flywheel structure 169.
It should be noted that the first pulley 1682, the belt, and the second pulley 1684 may be replaced by other structures. Such as first pulley 1682 and second pulley 1684, are coupled by a gear set.
Referring to fig. 8, fig. 8 is a schematic structural diagram of a second flywheel of an electronic device according to an embodiment of the present disclosure. The second flywheel structure 169 comprises a transmission wheel 1692, the transmission wheel 1692 is connected (such as fixed connection, gear connection and the like) with a second driving shaft 1634, the second driving shaft 1634 can drive the transmission wheel 1692 to rotate, the transmission wheel 1692 is provided with a barbed claw 1694, one end of the barbed claw 1694 is rotatably connected with the transmission wheel 1692, the other end of the barbed claw 1694 comprises a clamping side 1696 and a press-back side 1698, and the clamping side 1696 and the press-back side 1698 are oppositely arranged; the first belt pulley 1682 is sleeved on the transmission wheel 1692, and the inner side of the first belt pulley 1682 is provided with a protruding part 1688; when the transmission wheel 1692 rotates towards the first direction, the bayonet side 1696 at the other end of the bayonet claw 1694 is in bayonet joint with the protrusion 1688 and drives the first belt pulley 1682 to rotate; as the transfer wheel 1692 rotates in a second direction, the press-back side 1698 of the other end of the stab claw 1694 is pressed back by the protrusions 1688, causing the other end of the stab claw 1694 to rotate about the one end of the stab claw 1694, the first direction being opposite to the second direction.
The effect that the first pulley 1682 is not moved when the motor 161 rotates forward and the first pulley 1682 rotates reversely or the first pulley 1682 rotates when the motor 161 rotates forward and the first pulley 1682 rotates reversely can be realized by the barbed claw 1694 on the transmission wheel 1692 and the protrusion 1688 on the inner surface of the first pulley 1682. Specifically, one end of the barbed claw 1694 is rotatably connected with the transmission wheel 1692, the other end is a free end, one side of the free end is a clamping side 1696, the other side of the free end is a press-back side 1698, the clamping side 1696 is connected with the press-back side 1698, the press-back side 1698 is a smooth inclined surface, and the clamping side 1696 is a steep inclined surface. Thus, projection 1688 on the inner surface of first pulley 1682 can snap fit against snap side 1696, and drive wheel 1692, in turn, rotates first pulley 1682 via the engaged snap side 1696 and projection 1688. As the tab 1688 contacts the press-back side 1698, the tab 1688 gradually passes over the press-back side 1698 and presses back the press-back side 1698, i.e., the press-back side 1698 rotates about an end of the bayonet 1694, thereby immobilizing the first pulley 1682 and freewheeling the drive wheel 1692. The rotation of the first end of the barbed claw 1694 and the transmission wheel 1692 can be limited to one side only, and can only rotate towards the press-back side 1698, but can not rotate towards the clamping side 1696. Alternatively, the rotation of the first end of the barbed claw 1694 and the driving wheel 1692 may be limited to a certain extent, and may be limited to a smaller extent toward the clamping side 1696.
In some embodiments, the side of the inner surface of first pulley 1682 where projection 1688 contacts catch side 1696 is also a steeper slope and the side of projection 1688 where it contacts press back side 1698 is a smoother slope to engage the other end of catch 1694.
In some embodiments, the barbed grip may be provided on an inner surface of the first pulley, the outer surface of the driving wheel may be provided with a protrusion, and the protrusion of the driving wheel may be in a gear configuration.
In some embodiments, after the bayonet 1694 is pressed back, it needs to be restored to its pre-press back state so that the motor 161 will rotate in reverse, bringing the first pulley 1682 along. A first magnet 1693 can be disposed on the driving wheel 1692, a second magnet 1695 can be disposed on the other end of the bayonet 1694, the first magnet 1693 and the second magnet 1695 have opposite magnetism, and when the other end of the bayonet 1694 is pressed back, the other end of the bayonet 1694 is driven by the first magnet 1693 to return to the position before pressing back. In other embodiments, the restoring function may be implemented by a spring, a leaf spring, or the like. For example, one end of the spring is connected with the other end of the stabbing claw, the other end of the spring is fixed on the transmission wheel, when the other end of the stabbing claw is pressed back, the spring is compressed to enable the spring to have elastic restoring force, and after the protruding part and the stabbing claw are separated, the stabbing claw is restored to the state before being pressed back through the elastic restoring force.
In some embodiments, the first flywheel structure 167 can be configured similar to the second flywheel structure 169 to drive the roller 162, and when the motor 161 is rotating in the forward direction, one of the first flywheel structure 167 and the second flywheel structure 169 drives the corresponding wheel (the roller 162 or the first pulley 1682) to rotate, and when the motor 161 is rotating in the reverse direction, the other of the first flywheel structure 167 and the second flywheel structure 169 drives the corresponding wheel (the first pulley 1682 or the roller 162) to rotate. Specifically, when the motor 161 rotates forward, the motor 161 drives the roller 162 to rotate through the first flywheel structure 167, and when the motor 161 rotates backward, the first flywheel structure 167 idles (the roller 162 does not rotate), or when the motor 161 rotates backward, the motor 161 drives the roller 162 to rotate through the first flywheel structure 167, and when the motor 161 rotates forward, the first flywheel structure 167 idles (the roller 162 does not rotate).
The first flywheel structure comprises a transmission wheel, the transmission wheel is connected with a first driving shaft, the first driving shaft drives the transmission wheel to rotate, a thorn claw is arranged on the transmission wheel, one end of the thorn claw is rotatably connected with the transmission wheel, the other end of the thorn claw comprises a clamping side and a press-back side, and the clamping side and the press-back side are arranged oppositely; the roller is sleeved on the driving wheel, and the inner side of the roller is provided with a protruding part; when the driving wheel rotates towards the first direction, the bayonet side at the other end of the stabbing claw is in bayonet connection with the protruding part and drives the first belt pulley to rotate; when the driving wheel rotates towards the second direction, the pressing-back side of the other end of the stabbing and grabbing piece is pressed back by the protruding part, so that the other end of the stabbing and grabbing piece rotates around one end of the stabbing and grabbing piece, and the first direction is opposite to the second direction. The structure of the stabbing and protruding parts can adopt the same structure as the above embodiments, and the details are not repeated.
In some embodiments, the number of the traction wheels 164 is two, the two traction wheels 164 are connected by a transmission shaft 1686, the two traction wheels 164 are respectively disposed at two ends of the receiving cavity, and the second pulley 1684 drives the two traction wheels 164 to rotate by the transmission shaft 1686.
The two traction wheels 164 are distributed at two ends of the flexible display screen 140, the traction wheels 164 at two ends are driven by one transmission shaft 1686, and the two traction wheels 164 work simultaneously, so that the flexible display screen 140 can be uniformly stressed when being driven to move out of the shell 120.
In some embodiments, the number of the traction wheels 164 is two, two traction wheels 164 are connected to the second driving mechanism 168, the two traction wheels 164 are respectively disposed at two ends of the accommodating cavity, and the second driving mechanism 168 drives the two traction wheels 164 to rotate simultaneously. The second drive mechanism may drive the two traction wheels via a gear set or other drive shaft, respectively.
With continued reference to fig. 4, in some embodiments, the flexible display screen 140 includes a display surface 142 and a display back surface 144, the electronic device 100 further includes a pulling belt 146, the pulling belt 146 is disposed on the display back surface 144 of the flexible display screen 140, the pulling belt 146 is disposed on the pulling wheel 164, and when the driving mechanism drives the pulling wheel 164 to rotate, the pulling wheel 164 drives the flexible display screen 140 to extend out of the housing 120 through the opening via the pulling belt 146.
The traction belt 146 can be attached to the display back 144 of the flexible display screen 140, and the driving structure can drive the traction belt 146 to move, so that the flexible display screen 140 is driven to move, and the flexible display screen 140 can be better protected.
One end of the traction belt 146 may be fixedly connected to the roller 162, and the other end of the traction belt is fixedly connected to the traction wheel 164, the driving mechanism drives the traction wheel 164 to rotate, and the traction wheel 164 surrounds the traction belt 146 on the traction wheel 164 and drives the flexible display screen 140 to extend out of the housing 120 from the opening to be stretched.
