The electronic device 100 provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1 to 6, an electronic apparatus 100 according to an embodiment of the present invention includes first and

second brackets

10 and 20, a winding shaft 40, a display screen 30, a driving assembly, and a transmission assembly.

Specifically, the first bracket 10 is connected to the second bracket 20, and the second bracket 20 is movable in a first direction with respect to the first bracket 10. The winding shaft 40 is provided rotatably about its own axis to the second bracket 20. The driving component is arranged on the first support 10 and is connected with the second support 20, the transmission component is respectively connected with the driving component and the winding shaft 40, the first end of the display screen 30 is connected with the first support 10, the second end of the display screen 30 is connected with the winding shaft 40, the driving component drives the second support 20 to move in the first direction and drives the transmission component to move, and the transmission component drives the winding shaft 40 to rotate around the axis of the driving component so as to enable the display screen 30 to be wound on the winding shaft 40 or to be unfolded relative to the winding shaft 40.

In other words, the electronic device 100 according to the embodiment of the present invention, as shown in fig. 5, is mainly composed of the first and

second brackets

10 and 20 that are engaged with each other, the winding shaft 40 provided to the second bracket 20, the display screen 30 having flexibility, the driving assembly capable of providing the driving source, and the transmission assembly realizing the force transmission.

As shown in fig. 1 and 2, the first bracket 10 and the second bracket 20 are movably connected, and the second bracket 20 can move along a first direction relative to the first bracket 10, for example, the second bracket 20 can move toward the position of the first bracket 10 or move away from the position of the first bracket 10.

The display screen 30 is provided on the first and

second brackets

10 and 20, and a winding shaft 40 is provided on the second bracket 20. A first end of the display screen 30 is connected to the first bracket 10 and a second end of the display screen 30 is connected to the winding shaft 40.

As shown in fig. 3 to 4, since the second end of the display screen 30 can be wound around the winding shaft 40, the position of the second end of the display screen 30 can be controlled by controlling the rotation or movement of the winding shaft 40. For example, the second end of the display 30 can be wound around the winding shaft 40 or released from the winding shaft 40 by controlling the rotation direction of the winding shaft 40. By controlling the translation of the winding shaft 40 along the first direction, the second end of the display screen 30 can be driven to translate synchronously. By simultaneously controlling the rotation and translation of the winding shaft 40, the rotation and translation of the winding shaft 40 can be realized, and the automatic unfolding and storage of the display screen 30 can be further realized.

As shown in fig. 5, when the electronic apparatus 100 is placed horizontally, the first direction may be set to be the horizontal direction, so that the thickness of the electronic apparatus 100 in the up-down direction can be effectively reduced. As shown in fig. 2 and 6, when the second bracket 20 moves in the first direction, the distance between the first bracket 10 and the second bracket 20 gradually increases. The second end of the display screen 30 extends relative to the winding shaft 40 by the cooperation of the drive assembly and the winding shaft 40. When the second bracket 20 moves to the first preset position along the first direction, the state of the display screen 30 may be set to the extreme unfolding state, where the area of the display screen 30 is the largest.

As shown in fig. 1 and 5, when the second bracket 20 moves leftward, the distance between the first bracket 10 and the second bracket 20 gradually decreases. The second end of the display screen 30 is wound around the winding shaft 40 by the cooperation of the driving assembly and the winding shaft 40. When the second bracket 20 moves leftwards to the second preset position, the state of the display screen 30 can be set to the initial state, and the area of the display screen 30 is the smallest.

As shown in fig. 5 and 6, when the second bracket 20 moves rightward while dividing the first direction into left and right, the display screen 30 is unfolded; and when the second bracket 20 moves leftward, the display screen 30 is received.

Further, a driving assembly is provided on the first bracket 10 and can be connected with the second bracket 20. That is, the driving assembly is capable of driving the second bracket 20 to move in the first direction with respect to the first bracket 10. When both the first and

second brackets

10, 20 extend in a horizontal direction, the drive assembly is capable of displacing the second bracket 20 in a horizontal direction relative to the first bracket 10. It should be noted that, the driving assembly may drive the second bracket 20 to move in the first direction, and drive the winding shaft 40 to move in the first direction; or by driving the winding shaft 40 to move in the first direction, the second bracket 20 is driven to move in the first direction, which is not limited herein.

And, the drive assembly can drive the transmission assembly to move, and the transmission assembly is connected with the winding shaft 40. Therefore, when the driving assembly drives the winding shaft 40 to move along the first direction, the transmission assembly can synchronously drive the winding shaft 40 to rotate around the self axis, and the winding shaft 40 can synchronously move along the first direction along with the second bracket 20.

That is, the driving assembly and the transmission assembly cooperate, and the winding shaft 40 can rotate around its own axis while driving the second bracket 20 to displace in the first direction, so that the display screen 30 can be released from the winding shaft 40 or wound on the winding shaft 40, thereby realizing the enlargement and reduction of the display screen 30.

For example, when the driving assembly drives the transmission assembly to move rightward, the second bracket 20 moves in the rightward direction, and the winding shaft 40 can also move in the rightward direction. The drive assembly drives the winding shaft 40 to rotate counterclockwise about its own axis, the display screen 30 is released from the winding shaft 40, and the display screen 30 is stretched.

When the driving assembly drives the driving assembly to move in the left direction, the second bracket 20 moves in the left direction, and the winding shaft 40 can also move in the left direction. The transmission assembly drives the winding shaft 40 to rotate clockwise around the axis of the transmission assembly, the display screen 30 is wound on the winding shaft 40, and the display screen 30 is contracted.

The driving unit is not limited to a driving motor, and may be a mechanical structure capable of driving, external force of the electronic device 100, or the like.

Thus, according to the electronic device 100 of the embodiment of the present invention, the driving assembly is matched with the transmission assembly, so that the winding shaft 40 can be driven to rotate around its own axis and simultaneously can move along the first direction, so that the display screen 30 can be wound on the winding shaft 40 or be unwound relative to the winding shaft 40. The electronic equipment 100 has the advantages of being simple in structure, improving user experience and the like.

According to one embodiment of the present application, the drive assembly includes a support member, a first screw 52, a movable member 53, and a motor 54. Wherein the support member is provided on the first bracket 10. The first screw 52 is rotatably provided to the support. The movable member 53 is connected to the first screw rod 52, and when the movable member 53 rotates around the first screw rod 52, the movable member 53 is driven by the first screw rod 52 to move along the first direction, and the transmission assembly is connected to the movable member 53 and the winding shaft 40, respectively. A motor 54 is connected to the first screw 52 to drive the first screw 52.

That is, as shown in fig. 5, the driving assembly is mainly composed of a supporting member capable of performing an installation function, a first screw 52 provided to the supporting member, a movable member 53 movably connected to the first screw 52, and a motor 54 for providing a driving source. A support member is provided on the first bracket 10, and the support member can support the first screw 52. The motor 54 is connected to the first screw 52 and is capable of driving the first screw 52 to rotate on the support about the axis of the first screw 52.

When the first screw rod 52 rotates, the movable piece 53 is mounted on the first screw rod 52, so that the first screw rod 52 and the movable piece 53 are in threaded connection, and when the first screw rod 52 rotates along the axis of the first screw rod 52, the movable piece 53 can be driven to move along the axis of the first screw rod 52.

That is, as shown in fig. 5, when the first screw 52 rotates, the movable member 53 can be driven to move in the first direction by controlling the rotation direction of the first screw 52. The movable member 53 is connected to the transmission assembly, so that the movable member 53 can drive the transmission assembly to move along the first direction.

Further, since the transmission assembly is connected to the winding shaft 40, the winding shaft 40 is connected to the second bracket 20, and finally it is possible to realize that the winding shaft 40 and the second bracket 20 can move in the first direction.

And, the transmission assembly can drive the winding shaft 40 to rotate about its own axis, so that the display screen 30 can be released from the winding shaft 40 or wound on the winding shaft 40, thereby achieving enlargement and reduction of the display screen 30. The flexible screen is simple in arrangement and can be automatically telescopic.

In addition, compared with the prior art, the electronic device 100 of the present application can realize both the rotation of the winding shaft 40 and the expansion or contraction of the first bracket 10 and the second bracket 20 by only one motor 54, thereby realizing the automatic enlargement and contraction of the display screen 30. The size of the electronic device 100 can be effectively reduced, the light and thin design of the electronic device is facilitated, and compared with a mode of driving two motors 54, electric energy is saved, and the energy consumption of the device is reduced.

In some embodiments of the invention, the support is provided with a threaded hole passing through in the first direction. The transmission assembly comprises a second screw 61, a first gear 62 and a second gear 63. The first end of the second screw 61 is connected to the movable member 53 through a screw hole, and when the second screw 61 moves in the first direction, the second screw 61 is engaged with the screw hole, and the second screw 61 rotates about its own axis. The first gear 62 is disposed at the second end of the second screw 61, and the first gear 62 and the second screw 61 move synchronously. The second gear 63 is provided on the winding shaft 40 and moves synchronously with the winding shaft 40, and the second gear 63 is meshed with the first gear 62.

The cooperation between the first screw 52 and the second screw 61 will be described in detail with reference to the accompanying drawings.

As shown in fig. 5 and 6, a screw hole is provided in the support, and the screw hole penetrates in the first direction. The transmission assembly mainly consists of a second screw 61, a first gear 62 and a second gear 63. The second screw 61 passes through the screw hole, and the second screw 61 is screwed with the inner wall surface of the screw hole.

The left end of the second screw rod 61 is movably connected with the movable piece 53, and the second screw rod 61 is in threaded connection with the supporting piece. The right end of the second lead screw 61 is connected to the first gear 62, the second gear 63 is connected to the winding shaft 40 via the first gear 62, and the second gear 63 is engaged with the first gear 62.

For example, when the motor 54 drives the first screw 52 to rotate counterclockwise, the movable member 53 moves leftward in the axial direction of the first screw 52. The movable piece 53 is movably connected with the left end of the second screw rod 61, and the movable piece 53 can drive the second screw rod 61 to translate leftwards. Because the second screw rod 61 is in threaded connection with the supporting piece, when the second screw rod 61 translates leftwards, the second screw rod 61 can rotate around the axis of the second screw rod 61, and finally the display screen 30 is stored. Similarly, when the motor 54 drives the first screw rod 52 to rotate clockwise, the display screen 30 can be unfolded, which is not described herein. It should be noted that, when the first screw rod 52 rotates counterclockwise, the display screen 30 may be unfolded, and when the first screw rod 52 rotates clockwise, the display screen 30 may be stored, which is not limited herein.

The following describes in detail the fitting relationship between the first gear 62, the second gear 63 and the winding shaft 40 with reference to the drawings.

As shown in fig. 5 and 6, the first gear 62 is connected to the right end of the second screw 61, and the first gear 62 and the second screw 61 can move synchronously. Specifically, when the second screw 61 moves leftward, the first gear 62 can also move leftward. When the second screw 61 moves rightward, the first gear 62 can also move rightward. When the second screw 61 rotates around its own axis, the first gear 62 can also rotate.

Since the first gear 62 is engaged with the second gear 63, the second gear 63 is mounted on the winding shaft 40, and the winding shaft 40 is mounted on the second bracket 20. Therefore, when the first gear 62 moves rightward, the second gear 63 and the winding shaft 40 can be pushed to move rightward, and when the first gear 62 rotates, the second gear 63 can also rotate, so that the winding shaft 40 rotates along the axis thereof while moving rightward, and the display screen 30 is unfolded on the winding shaft 40. When the first gear 62 moves leftward, on the one hand, the winding shaft 40 can be rotated along its own axis while moving leftward by the meshing action between the first gear 62 and the second gear 63; on the other hand, the winding shaft 40 may rotate along its own axis while moving rightward by the restoring member between the first bracket 10 and the second bracket 20, and the restoring member cooperates with the motor 54, for example, a spring is provided on the first bracket 10 and the second bracket 20, and when the motor 54 drives the second screw 61 to move leftward, the winding shaft 40 moves leftward under the restoring force of the spring, so that the engagement between the first gear 62 and the second gear 63 is always maintained.

According to one embodiment of the present application, the first gear 62 and the second gear 63 are both bevel gears, and the axial directions of the two bevel gears are perpendicular.

That is, by providing the first gear 62 and the second gear 63 as two bevel gears perpendicular to each other, the first gear 62 and the second gear 63 are meshed to form a bevel gear. The bevel gears can transmit motion and power between two intersecting shafts, namely, the first gear 62 is driven to rotate by the second screw 61, and the first gear 62 drives the second gear 63 to rotate, so that the winding shaft 40 and the second gear 63 synchronously rotate. By providing a bevel gear, the power of the motor 54 is conveniently transmitted to the winding shaft 40, which is beneficial to the rotation and screen movement of the winding shaft 40.

In some embodiments of the present application, the support includes a first mounting portion 511 and a second mounting portion 512. The first mounting portion 511 is provided on the first bracket 10, and a first end of the first screw 52 is connected to the first mounting portion 511. The second mounting portion 512 is disposed on the first bracket 10 and is spaced from the first mounting portion 511, a threaded hole is formed in the second mounting portion 512, and a second end of the first screw rod 52 is connected to the second mounting portion 512. The movable member 53 is provided between the first mounting portion 511 and the second mounting portion 512, and the motor 54 is provided at the first mounting portion 511 or the second mounting portion 512.

Specifically, the support member is mainly composed of a first mounting portion 511 and a second mounting portion 512 which can play a supporting role, and the first mounting portion 511 and the second mounting portion 512 are respectively provided at intervals on the first bracket 10, and the first mounting portion 511 and the second mounting portion 512 are provided opposite to each other, so that an influence on the movement of the second bracket 20 can be avoided. As shown in fig. 5 and 6, at the time of assembly, the left end of the first screw 52 may be connected to the first mounting portion 511, and the right end of the first screw 52 may be connected to the second mounting portion 512. The first screw 52 may be partially or entirely located between the first mounting portion 511 and the second mounting portion 512. And the left end of the second screw 61 is also connected to the first mounting portion 511, and the right end of the second screw 61 is connected to the second mounting portion 512. And the first screw rod 52 and the second screw rod 61 are connected through the movable member 53, so that the rotation of the first screw rod 52 can be converted into the translation of the second screw rod 61. Further, since the second mounting portion 512 is provided with a threaded hole, the second screw 61 is screwed with the threaded hole, and thus the translational movement of the second screw 61 can be converted into two modes of translational movement and rotational movement.

That is, as shown in fig. 5 and 6, when the motor 54 drives the first screw rod 52 to rotate on the first mounting portion 511 and the second mounting portion 512, the movable piece 53 is driven to move in the first direction. The movable member 53 drives the second screw 61 to perform linear movement along the first direction, and simultaneously, the second screw 61 rotates relative to the second mounting portion 512. The first gear 62 rotates synchronously with the second screw 61, the first gear 62 drives the second gear 63 to rotate, and the second gear 63 drives the winding shaft 40 to rotate synchronously therewith. The rotation direction of the first screw rod 52 is driven by the motor 54, and finally the winding shaft 40 can be rotated in a certain direction, so that the display screen 30 can be released from the winding shaft 40 or wound on the winding shaft 40, thereby realizing the enlargement and the reduction of the display screen 30. The motor 54 may be a motor that avoids manually pulling or collapsing the display screen 30, optimizing the user experience.

According to one embodiment of the present application, the support further comprises a guide rod 513, a first end of the guide rod 513 is connected to the first mounting portion 511, a second end of the guide rod 513 is connected to the second mounting portion 512, and the movable member 53 is movably connected to the guide rod 513.

That is, the movement of the movable member 53 and the second screw 61 can be guided by providing the guide rod 513. For example, as shown in fig. 5 and 6, the left end of the guide bar 513 is connected to the first mounting portion 511, and the right end of the guide bar 513 is connected to the second connecting portion. On the one hand, the guide rod 513 connects the first mounting portion 511 with the second connecting portion, which can play a role of fixing and supporting, thereby ensuring that the distance between the first mounting portion 511 and the second connecting portion is unchanged, and enabling the second screw 61 to accurately and stably move on the second bracket 20. On the other hand, the movable member 53 can move along the guide rod 513, and the guide rod 513 can guide the movement of the movable member 53, so that the movement of the movable member 53 is smoother and the repeated movement of the movable member 53 is facilitated.

According to one embodiment of the present invention, the first and second mounting

portions

511 and 512 are spaced apart along a first direction, and axes of the guide rod 513, the first and

second screw rods

52 and 61 each extend along the first direction.

That is, the first mounting portion 511 and the second mounting portion 512 are disposed at intervals in the horizontal direction, and the disposed positions of the first mounting portion 511 and the second mounting portion 512 correspond. The axes of the guide rod 513, the first screw 52, and the second screw 61 may be disposed in parallel and each extend along the first direction. The electronic device is simple in arrangement, the whole structure of the driving assembly is more compact, and the electronic device is easy to lighten and thin.

In some embodiments of the present application, the first and second mounting

portions

511 and 512 are rectangular blocks, respectively, and the guide rods 513, the first and

second screw rods

52 and 61 are arranged at intervals along the length direction of the first or second mounting

portions

511 and 512.

That is, as shown in fig. 5 and 6, by providing the first mounting portion 511 and the second mounting portion 512 as rectangular blocks and providing the first mounting portion 511 and the second mounting portion 512 as regular shapes, the processing design is facilitated. And by disposing the guide rods 513, the first screw rods 52 and the second screw rods 61 to be spaced apart along the length direction of the first mounting portion 511 or the second mounting portion 512, it is possible to enable compact arrangement of the respective structural brackets, reducing the thickness and the overall volume of the electronic apparatus 100.

According to one embodiment of the present invention, the number of the guide rods 513 is two, the first screw rod 52 and the second screw rod 61 are located between the two guide rods 513, and the movable member 53 is connected to the two guide rods 513, respectively.

That is, as shown in fig. 5 and 6, the number of the guide rods 513 is set to two. The two guide rods 513 are disposed opposite to each other and are connected to the first and second mounting

portions

511 and 512. The first screw 52 and the second screw 61 are located between two guide rods 513, as shown in fig. 5, one guide rod 513 being located behind the first screw 52 and the other guide rod 513 being located in front of the second screw 61. The movable member 53 is sleeved on the outer circumferences of the two guide rods 513, and is movable on the guide rods 513 in the first direction. The two guide rods 513 not only can play a role of supporting and fixing, so that the movable piece 53 can move smoothly along the first direction; it is also possible to limit the movement direction of the movable member 53, avoiding the movable member 53 from being deviated during the movement.

According to one embodiment of the present application, the movable member 53 includes a connection block connected with two guide rods 513, a first screw 52, and a second screw 61, and a stopper plate disposed above the connection block, as shown in fig. 5 and 6. As shown in fig. 4, when the movable member 53 moves rightward to the position where the display screen 30 is fully unfolded, the right end of the stopper plate can be stopped by the second mounting portion 512, and the second screw 61 cannot move further rightward, so that the display screen 30 is prevented from being damaged by pulling. Similarly, when the movable member 53 moves leftwards to the position where the display screen 30 is fully stored, the left end of the stopper plate can be stopped against the first mounting portion 511, and the second screw 61 cannot move leftwards continuously, so that the display screen 30 is prevented from being damaged by extrusion.

It should be noted that, the electronic device 100 of the present application may be used not only in portable consumer electronic devices, but also in electronic products such as tablet computers and vehicle-mounted intelligent terminals.
