In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 7, an electronic device according to an embodiment of the present invention includes a first body 100, a second body 200, a flexible display 300, and a reciprocating driving mechanism 400. The first body 100 and the second body 200 are base members, and the first body 100 and the second body provide a mounting base for the flexible display 300 and the reciprocating driving mechanism 400. The first body 100 is slidably engaged with the second body 200, and specifically, the first body 100 and the second body 200 can be considered as two relatively moving parts of the electronic device. The reciprocating driving mechanism 400 is a power member for providing power for the relative sliding of the first body 100 and the second body 200.
The reciprocating drive mechanism 400 includes a gear assembly 410 and a bi-directional rack 420, the gear assembly 410 being engaged with the bi-directional rack 420, and the gear assembly 410 moving about the bi-directional rack 420. One of the gear assembly 410 and the bidirectional rack assembly 420 is connected to the first body 100, and the other is connected to the second body 200, and the gear assembly 410 and the bidirectional rack assembly 420 drive the second body 200 to reciprocate along a first line with respect to the first body 100. The gear assembly 410 moves around the bidirectional rack 420, so that the motion track of the gear assembly 410 relative to the bidirectional rack 420 is closed loop, and the gear assembly 410 can drive the first body 100 and the second body 200 to reciprocate by unidirectional circulation motion around the bidirectional rack 420.
One end of the flexible display screen 300 is fixedly connected to the first body 100, the flexible display screen 300 is slidably engaged with the second body 200, and the flexible display screen 300 can slide along the surface of the second body 200.
Specifically, under the condition that the second body 200 slides in the direction away from the first body 100, the flexible display screen 300 slides from the first side of the second body 200 to the second side of the second body 200, so that the single-sided display area of the electronic device is increased. Under the condition that the second body 200 slides in the direction close to the first body 100, the flexible display screen 300 slides from the second side of the second body 200 to the first side of the second body 200, so that the single-sided display area of the electronic device is reduced. Further, the first side of the second body 200 is opposite to the second side of the second body 200.
The second body 200 slides in a direction away from the first body 100 to be in a first state, and the second body 200 slides in a direction close to the first body 100 to be in a second state. In the process of switching the first state and the second state of the reciprocating driving mechanism 400 described in the above embodiment, the rotation direction of the gear assembly 410 may be kept unchanged, and thus the user operation may be simplified, so that the switching between the first state and the second state may be smoother. Moreover, when the scheme in the above embodiment is switched between the first state and the second state, the reciprocating driving mechanism 400 and/or the flexible display screen 300 can be prevented from being overloaded, so as to protect the reciprocating driving mechanism 400 and/or the flexible display screen 300.
Referring to fig. 6 to 13, the gear assembly 410 may be fixedly disposed at the second body 200, the bidirectional rack 420 may be movably disposed at the first body 100, and the bidirectional rack 420 is switched between a first position and a second position with respect to the first body 100. With the bi-directional rack 420 in the first position, the bi-directional rack 420 is located on a first side of the gear assembly 410. With the bi-directional rack 420 in the second position, the bi-directional rack 420 is located on a second side of the gear assembly 410. The first side of the gear assembly 410 is opposite the second side of the gear assembly 410. Specifically, the bidirectional rack 420 can move along a second straight line relative to the first body 100, and the second straight line is perpendicular to the first straight line. This embodiment provides a solution for the gear assembly 410 to rotate about the bi-directional rack 420. In this embodiment, the gear assembly 410 drives the bidirectional rack 420 to move relative to the gear assembly 410 by rotating, so as to drive the first body 100 to move relative to the second body 200. When the gear assembly 410 moves to the end of the bidirectional rack 420, the rotation of the gear assembly 410 acts to move the bidirectional rack 420 relative to the first body 100 such that the bidirectional rack 420 can be switched between a first side of the gear assembly 410 and a second side of the gear assembly 410.
Referring to fig. 8 to 10, the reciprocating drive mechanism 400 includes a rack rail 450, and the rack rail 450 is perpendicular to the bidirectional rack 420, that is, the rack rail 450 is guided in a direction perpendicular to the bidirectional rack 420. The bidirectional rack 420 is slidably engaged with the rack guide 450, and the bidirectional rack 420 is slidable along the rack guide 450 between a first position and a second position. Specifically, the rack guide 450 is fixedly disposed on the first body 100 to guide the bidirectional rack 420 to move along the second straight line through the rack guide 450.
Referring to fig. 6 and 8, when the first and second bodies 100 and 200 are switched from the first state to the second state, the gear assembly 410 moves to the first end of the bidirectional rack 420. The gear assembly 410 continues to rotate and acts to move the bi-directional rack 420 relative to the first body 100 such that the bi-directional rack 420 is slid from the first side of the gear assembly 410 to the second side of the gear assembly 410. After the bidirectional rack 420 moves to the second side of the gear assembly 410, the gear assembly 410 continues to rotate and moves along the bidirectional rack 420, thereby driving the second body 200 to move along the first straight line relative to the first body 100. Similarly, when the first body 100 and the second body 200 are switched from the second state to the first state, the gear assembly 410 acts on the bidirectional rack 420, so that the bidirectional rack 420 slides from the first side of the second lateral gear assembly 410 of the gear assembly 410.
There are many embodiments in which the bidirectional rack 420 is movable along the second straight line with respect to the first body 100, and for example, a straight groove slidably engaged with the bidirectional rack 420 may be further provided on the first body 100. The present embodiment does not limit the specific embodiment in which the bidirectional rack 420 is movable along the second straight line with respect to the first body 100.
Referring to fig. 9 and 10, the reciprocating driving mechanism 400 further includes a first bidirectional rack positioning element 430 and a second bidirectional rack positioning element 440, the first bidirectional rack positioning element 430 and the second bidirectional rack positioning element 440 are both disposed parallel to the bidirectional rack 420, the bidirectional rack 420 is disposed between the first bidirectional rack positioning element 430 and the second bidirectional rack positioning element 440, the bidirectional rack 420 abuts against the first bidirectional rack positioning element 430 when the bidirectional rack 420 is located at the first position, and the bidirectional rack 420 abuts against the second bidirectional rack positioning element 440 when the bidirectional rack 420 is located at the second position. Specifically, the first and second bi-directional rack positioning members 430 and 440 are fixedly disposed on the first body 100 or the second body 200, so that the bi-directional rack 420 is blocked from moving relative to the first body 100 or the second body 200 by the first and second bi-directional rack positioning members 430 and 440. In addition, the first and second bidirectional rack positioning members 430 and 440 may also be fixedly disposed on the rack rail 450, so that the bidirectional rack 420 is hindered from sliding along the rack rail 450 by the first and second bidirectional rack positioning members 430 and 440.
There are many specific embodiments of the first and second dual rack positioning members 430 and 440, for example, the first and second dual rack positioning members 430 and 440 may be positioning blocks, or positioning bars, positioning bosses, or positioning posts, etc., and the specific structures of the first and second dual rack positioning members 430 and 440 are not limited in this application.
In the electronic device disclosed in another embodiment of the present invention, the bidirectional rack 420 is fixedly disposed on the second body 200, the gear assembly 410 is movably disposed on the first body 100, and the gear assembly 410 is switched between a third position and a fourth position relative to the first body 100. With the gear assembly 410 in the third position, the gear assembly 410 is located on a first side of the bi-directional rack 420. With the gear assembly 410 in the fourth position, the gear assembly 410 is located on a second side of the bi-directional rack 420. A first side of the bidirectional rack 420 is opposite a second side of the bidirectional rack 420. Specifically, the gear assembly 410 is movable along a third line relative to the first body 100, and the third line is perpendicular to the first line. This embodiment provides another solution for the gear assembly 410 to rotate about the bi-directional rack 420. In this embodiment, the gear assembly 410 drives the bidirectional rack 420 to move relative to the gear assembly 410 by rotating, so as to drive the second body 200 to move relative to the first body 100. When the gear assembly 410 moves to the end of the bi-directional rack 420, the rotation of the gear assembly 410 acts on the bi-directional rack 420. Since the bidirectional rack 420 is fixedly disposed on the second body 200, the gear assembly 410 can move relative to the first body 100 under the reaction force of the bidirectional rack 420, so that the gear assembly 410 can be switched between a first side of the bidirectional rack 420 and a second side of the bidirectional rack 420.
When the first body 100 and the second body 200 are switched from the first state to the second state, the gear assembly 410 moves to the first end of the bidirectional rack 420. The gear assembly 410 continues to rotate and acts on the bi-directional rack 420. When the gear assembly 410 acts on the bidirectional rack 420, a reaction force is applied to the bidirectional rack 420. The bidirectional rack 420 is fixedly disposed on the second body 200, and the gear assembly 410 is movably disposed on the first body 100. The gear assembly 410 moves from a first side of the bidirectional rack 420 to a second side of the bidirectional rack 420 under the reaction force of the bidirectional rack 420. After the gear assembly 410 moves to the second side of the bidirectional rack 420, the gear assembly 410 continues to rotate and moves along the bidirectional rack 420, thereby driving the second body 200 to move along the first straight line relative to the first body 100. Similarly, when the first body 100 and the second body 200 are switched from the second state to the first state, the bidirectional rack 420 reacts to the gear assembly 410, so that the gear assembly 410 moves from the second side of the bidirectional rack 420 to the first side of the bidirectional rack 420.
There are many embodiments in which the gear assembly 410 can move along the third straight line relative to the first body 100, for example, a linear guide rail or a linear groove or the like can be provided on the first body 100 to be slidably engaged with the gear assembly 410, and this embodiment is not limited to the specific embodiment in which the gear assembly 410 can move along the third straight line relative to the first body 100.
The reciprocating drive mechanism 400 includes a gear set guide rail perpendicular to the bi-directional rack 420, a first gear set positioning member and a second gear set positioning member, a gear assembly 410 slidably engaged with the gear set guide rail, and the gear assembly 410 slidable along the gear set guide rail between a third position and a fourth position. The first gear set positioning element and the second gear set positioning element are fixedly disposed on the first body 100. When the gear assembly 410 is located at the third position, the gear assembly 410 stops against the first gear set positioning element. When the bidirectional rack 420 is located at the second position, the gear assembly 410 is stopped against the second gear set positioning element.
The first gear set positioning element and the second gear set positioning element may be a positioning block, a positioning strip, a positioning boss, a positioning column, or the like.
Referring to fig. 9 to 13, the bidirectional rack 420 includes a driving tooth group 431 and a guide groove 432, the guide groove 432 is disposed along a circumferential direction of the driving tooth group 431, the gear assembly 410 includes a gear plate 411 and a guide pillar 412, the guide pillar 412 protrudes from a side of the gear plate 411 adjacent to the bidirectional rack 420, the guide pillar 412 is slidably fitted with the guide groove 432, and the gear plate 411 is engaged with the driving tooth group 431. In this embodiment, the guide column 412 is slidably engaged along the guide slot 432, and can not guide the movement of the gear assembly 410 relative to the bidirectional rack 420 through the guide slot 432, and can also provide support for the gear assembly 410 through the guide slot 432, so as to ensure that the gear assembly 410 can be engaged with the bidirectional rack 320 more stably. Further, the driving teeth 431 include a plurality of cylindrical protrusions, and the plurality of cylindrical protrusions are arranged equidistantly along a straight line, so that the gear assembly 410 can be engaged with the driving teeth 431 from both sides of the bidirectional rack 420. Further, a roller may be disposed on the guiding post 412, and the roller is disposed in the guiding groove 432, so as to reduce the friction between the guiding post 412 and the guiding groove 432.
Referring to fig. 8 and 9, the reciprocating drive mechanism 400 includes a drive member 460, the drive member 460 is drivingly connected to the gear assembly 410, and the drive member 460 drives the gear assembly 410 to move about the bi-directional rack 420. Optionally, the driving member 460 is a driving motor. Further, a kinetic energy output shaft of the driving motor is fixedly connected with the gear assembly 410 to drive the gear assembly 410 to rotate by the driving motor. The gear assembly 410 acts upon the bi-directional rack 420 such that the gear assembly 410 rotates relative to the bi-directional rack 420 about the bi-directional rack 420.

In this case, the first body 100 and the second body 200 are slidably connected by the first connection portion 110 and the second connection portion 210, so as to facilitate the assembly of the first body 100 and the second body 200; meanwhile, at least a portion of the second body 200 is sleeved on the first body 100, so that the electronic device has a more compact structure, other components of the electronic device can be disposed in the second body 200, and the first body 100 can be only a rear cover of the electronic device, thereby facilitating the overall layout of the electronic device.
Of course, in order to prevent the first body 100 and the second body 200 from being locked, the first connecting portion 110 may be disposed on both opposite side edges of the first body 100, and correspondingly, the second connecting portion 210 may be disposed on both opposite side edges of the second body 200, and the first body 100 and the second body 200 may be slidably connected through the cooperation of the first connecting portion 110 and the second connecting portion 210. This way, a better guiding effect can be achieved, so that the first body 100 can better slide relative to the second body 200, thereby preventing the first body 100 and the second body 200 from being locked.
Alternatively, one of the first connecting portion 110 and the second connecting portion 210 may be a sliding groove, and the other may be a protrusion, and the sliding groove and the protrusion may be in sliding fit. Under the circumstances, the first body 100 and the second body 200 can be slidably connected through the sliding fit of the sliding groove and the protrusion, and the sliding groove and the protrusion can play a guiding role, so that the first body 100 can better slide relative to the second body 200, and the first body 100 can better drive the flexible display screen 300 to be unfolded or folded.

Specifically, the linear electromagnetic guide 500 is only partially disposed in the linear electromagnetic guide groove 600, so that the flexible display screen 300 on the first side of the second body 200 is driven to move linearly relative to the second body 200 through the linear electromagnetic guide 500 and the linear electromagnetic guide groove 600, thereby ensuring the smoothness of the display surface of the flexible display screen 300.
Referring to fig. 2 and 4, a supporter 310 is provided at one end of the flexible display 300 connected to the second body 200, and the supporter 310 is fixedly connected to the linear electromagnetic guide groove 600.

Of course, the flexible display 300 may also extend from the second side of the second body 200 to the first side of the second body 200 along the surface of the roller 700.
The roller 700 not only serves to position the flexible display 300 but also to change the moving direction of the flexible display 300.
