[0002] With the development of technology, the development of electronic devices is also getting faster and faster. At the same time, users have higher and higher requirements for electronic devices. Foldable electronic devices have a larger display area in the unfolded state and occupy a smaller storage space in the folded state. Therefore, the application of foldable electronic devices is becoming more and more extensive.

For example, when an inward-folding electronic device is folded, the flexible display screen has a small bending radius, which can cause the flexible display screen to be too long, which can easily lead to creases or damage to the flexible display screen. When an outward-folding electronic device is folded, the flexible display screen has a large bending radius, which can easily lead to the flexible display screen being pulled and deformed, or even causing the flexible display screen to break. Therefore, when a folding electronic device is folded, the flexible display screen is easily damaged, which ultimately leads to a shorter service life of the flexible display screen.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0031] like Figures 1 to 8 As shown, an embodiment of the present application provides an electronic device, which includes a first shell 100, a second shell 200, a hinge assembly 300, a flexible screen assembly 400, a first driving assembly 500 and a first transmission assembly 600.

[0032] Among them, the first shell 100 and the second shell 200 are basic components of the electronic device, which together constitute the shell of the electronic device and can provide an installation basis for other structural parts of the electronic device. And the first shell 100 and the second shell 200 can protect other structural parts of the electronic device. In the embodiment of the present application, the first shell 100 and the second shell 200 can rotate relative to each other so that the electronic device can switch between the unfolded state and the folded state. The electronic device has a larger display area in the unfolded state, providing a better visual experience for the user, and occupies a smaller storage space in the folded state, which is easy to carry and store. Specifically, the first shell 100 and the second shell 200 are rotated together through the shaft assembly 300, so that the first shell 100 and the second shell 200 can rotate relative to each other, so that the electronic device can switch between the unfolded state and the folded state.

[0033] The flexible screen assembly 400 is a display assembly of an electronic device. The flexible screen assembly 400 has a first section and a second section. When the electronic device is in an unfolded state, the first section and the second section are on the same plane and together form a display surface. The electronic device has a larger display area. When the electronic device is in a folded state, the first section and the second section are opposite and overlapped, and the electronic device occupies a smaller storage space.

[0034] In addition, the first section of the flexible screen assembly 400 is slidably matched with the first shell 100, and the second section of the flexible screen assembly 400 is arranged on the second shell 200. During the folding process of the inward-folding electronic device, the first section of the flexible screen assembly 400 can slide in the direction away from the hinge assembly 300, and the redundant length of the flexible display screen 420 of the flexible screen assembly 400 can be moved in the direction away from the hinge assembly 300, thereby preventing the flexible display screen 420 from being squeezed out or damaged when the inward-folding electronic device is folded; during the folding process of the outward-folding electronic device, the first section of the flexible screen assembly 400 can slide in the direction close to the hinge assembly 300, providing a longer flexible display screen 420 at the bending part of the flexible display screen 420, thereby preventing the flexible display screen 420 from being pulled and deformed when the outward-folding electronic device is folded.

[0035] The first driving component 500 is a driving component of the electronic device, used to generate a driving force to drive the flexible screen component 400 to move. The first transmission component 600 is a transmission component of the electronic device, used to transmit the driving force generated by the first driving component 500 to the flexible screen component 400 to obtain the desired moving direction and moving speed.

[0036] The first transmission component 600 includes a first transmission member 610 and a second transmission member 620. The first transmission member 610 is slidably matched with the shaft assembly 300, and the second transmission member 620 is connected to the first section of the flexible screen assembly 400. In the process of the first transmission member 610 sliding along the shaft assembly 300, the second transmission member 620 can be driven to approach or move away from the first transmission member 610, so as to drive the first section of the flexible screen assembly 400 to slide in the direction of approaching or moving away from the shaft assembly 300. That is, the first transmission member 610 and the second transmission member 620 can cooperate to convert the sliding along the shaft assembly 300 into the sliding perpendicular to the shaft assembly 300, thereby changing the moving direction.

[0037] The first driving assembly 500 includes a first driving member 510, a first transmission bevel gear 520 and a first fixed bevel gear 530. The first driving member 510 is connected to the first transmission bevel gear 520, and the first transmission bevel gear 520 is meshed with the first fixed bevel gear 530. The first driving member 510 can drive the first transmission bevel gear 520 to rotate around the gear shaft of the first fixed bevel gear 530, and the first transmission bevel gear 520 can rotate around the gear shaft of the first transmission bevel gear 520. The first transmission bevel gear 520 can drive the first transmission member 610 to slide along the rotating shaft assembly 300 during the rotation process. That is, the first transmission bevel gear 520 can be rotated in the first driving assembly 500, and the first transmission bevel gear 520 can drive the first transmission member 610 to slide along the rotating shaft assembly 300 during the rotation process, thereby driving the first transmission member 610 to slide along the rotating shaft assembly 300.

[0038] During the folding process of the electronic device, the first driving member 510 drives the first transmission bevel gear 520 to rotate around the gear shaft of the first fixed bevel gear 530, the first transmission bevel gear 520 drives the first transmission member 610 to slide along the shaft assembly 300, and drives the first section of the flexible screen assembly 400 to move in a direction close to or away from the shaft assembly 300 through the second transmission member 620.

[0039] Specifically, during the folding process of the inward-folding electronic device, the first section of the flexible screen assembly 400 can be driven to move in a direction away from the hinge assembly 300, and the redundant length of the flexible display screen 420 of the flexible screen assembly 400 can be moved in a direction away from the hinge assembly 300, thereby preventing the flexible display screen 420 from being squeezed out or damaged when the inward-folding electronic device is folded; during the folding process of the outward-folding electronic device, the first section of the flexible screen assembly 400 can be driven to move in a direction close to the hinge assembly 300, providing a longer flexible display screen 420 at the bending part of the flexible display screen 420, thereby preventing the flexible display screen 420 from being pulled and deformed when the outward-folding electronic device is folded.

[0040] Therefore, the electronic device of the embodiment of the present application can prevent the flexible display screen 420 from being pulled or squeezed and damaged during the folding process of the electronic device, thereby achieving the purpose of protecting the flexible display screen 420 and solving the problem that the flexible screen assembly 400 is easily damaged during the folding process of the electronic device.

[0041] In the embodiment of the present application, the first drive assembly 500 also includes a first drive sleeve 540, the first transmission bevel gear 520 and the first fixed bevel gear 530 are both disposed within the first drive sleeve 540, the first transmission bevel gear 520 is connected to the first drive sleeve 540, and the first transmission bevel gear 520 can drive the first transmission member 610 to slide along the rotating shaft assembly 300 through the first drive sleeve 540.

[0042] On the one hand, the first drive sleeve 540 can provide an installation basis for the first transmission bevel gear 520 and the first fixed bevel gear 530, and provide protection to prevent gear meshing from damaging other structural parts; on the other hand, the first drive sleeve 540 can serve as an intermediate component to drive the first transmission component 610 to slide along the rotating shaft assembly 300.

[0043] The first transmission bevel gear 520 is connected to the first drive sleeve 540. When the first transmission bevel gear 520 moves, it can drive the first drive sleeve 540 to slide along the rotating shaft assembly 300. The first drive sleeve 540 can drive the first transmission member 610 to slide along the rotating shaft assembly 300, thereby realizing that the first transmission bevel gear 520 drives the first transmission member 610 to slide along the rotating shaft assembly 300 through the first drive sleeve 540.

[0044] In the embodiment of the present application, the side surface of the first transmission bevel gear 520 faces the inner surface of the first drive sleeve 540, and the inner surface of the first drive sleeve 540 is provided with a first groove 541, and the first groove 541 is arranged along the circumference of the first drive sleeve 540. The side surface of the first transmission bevel gear 520 is provided with a first convex portion 521, and the first convex portion 521 is eccentrically arranged relative to the gear shaft of the first transmission bevel gear 520. The first convex portion 521 is slidably matched with the first groove 541 to drive the first drive sleeve 540 to move along the rotating shaft assembly 300.

[0045] The first transmission bevel gear 520 is meshed with the first fixed bevel gear 530 . During the rotation of the first transmission bevel gear 520 , it not only rotates around its own gear shaft, but also revolves around the gear shaft of the first fixed bevel gear 530 .

[0046] The first convex portion 521 is eccentrically arranged relative to the gear shaft of the first transmission bevel gear 520. During the rotation of the first transmission bevel gear 520, the first convex portion 521 rotates around the gear shaft of the first transmission bevel gear 520 and rotates around the gear shaft of the first fixed bevel gear 530 at the same time. Therefore, in the axial direction of the first drive sleeve 540, the first convex portion 521 reciprocates, and the first groove 541 is arranged along the circumference of the first drive sleeve 540. The first convex portion 521 and the second groove are slidably matched. Therefore, during the rotation of the first transmission bevel gear 520, the first convex portion 521 can drive the first drive sleeve 540 to move along the rotating shaft assembly 300.

[0047] In the embodiment of the present application, the shaft assembly 300 includes a first shaft 310, which is disposed on the first shell 100. The first shaft 310 includes a first shaft fixing section 311 and a first shaft rotating section 312. The first shaft rotating section 312 is rotationally connected to the first shaft fixing section 311. For example, the first shaft rotating section 312 is connected to the first shaft fixing section 311 through a connecting sleeve 313. The first shaft fixing section 311 is fixedly connected to one end of the connecting sleeve 313, and the first shaft rotating section 312 is rotationally connected to the other end of the connecting sleeve 313.

[0048] The first driving member 510 and the first transmission bevel gear 520 are arranged on the first shaft rotating section 312, and the rotation states of the first shaft fixed section 311 and the first shaft rotating section 312 of the first shaft 310 are different. The first shaft fixed section 311 is relatively fixed, and the first shaft rotating section 312 is relatively rotating. In addition, the first driving member 510 and the first transmission bevel gear 520 are arranged on the first shaft rotating section 312, and the first shaft rotating section 312 can drive the first driving member 510 and the first transmission bevel gear 520 to rotate, and the first fixed bevel gear 530 is arranged on the first shaft fixed section 311, which can realize the fixation of the first fixed bevel gear 530.

[0049] The first driving member 510 can drive the first transmission bevel gear 520 to rotate through the first rotating shaft rotating section 312, and the first transmission member 610 is slidably matched with the first rotating shaft fixed section 311. The first driving member 510 can be connected to the first housing 100, and when the first housing 100 rotates relative to the second housing 200, the first driving member 510 can be driven to rotate, and the first driving member 510 can drive the first transmission bevel gear 520 to rotate through the first rotating shaft rotating section 312, and the first rotating shaft fixed section 311 can realize the fixation of the first fixed bevel gear 530, and the first transmission bevel gear 520 is meshed with the first fixed bevel gear 530. During the rotation of the first transmission bevel gear 520, it has both self-rotation around its own gear shaft and orbital revolution around the gear shaft of the first fixed bevel gear 530. The first convex portion 521 of the first transmission bevel gear 520 cooperates with the first concave groove 541 of the first drive sleeve 540 to drive the first drive sleeve 540 to move along the rotating shaft assembly 300 , thereby driving the first transmission member 610 to slide along the rotating shaft assembly 300 .

[0050] Therefore, the first driving component 500 can drive the first transmission member 610 to slide along the rotating shaft component 300 by using the rotation of the first housing 100. Of course, the first driving component 500 can also be other driving components that are separately provided, such as a driving motor.

[0051] In the embodiment of the present application, a first sleeve 511 is provided on the outer periphery of the first shaft rotating section 312, and the first sleeve 511 is fixedly connected to the first shaft rotating section 312, and the gear shaft of the first transmission bevel gear 520 is provided on the outer periphery of the first sleeve 511, and the gear shaft of the first transmission bevel gear 520 extends along the radial direction of the first sleeve 511. It can be realized that when the first shaft rotating section 312 rotates, the first transmission bevel gear 520 can be driven to rotate around the first shaft rotating section 312, that is, the first transmission bevel gear 520 can be driven to revolve around the gear shaft of the first fixed bevel gear 530.

[0052] Optionally, the first sleeve 511 and the gear shaft of the first transmission bevel gear 520 may be integrally arranged, that is, the gear shaft of the first transmission bevel gear 520 may be integrally extended radially outwardly from the outer periphery of the first sleeve 511. Of course, the gear shaft of the first transmission bevel gear 520 may also be separately arranged and then connected to the outer periphery of the first sleeve 511.

[0053] In the embodiment of the present application, the first housing 100 is provided with a first connecting gear 110, the second housing 200 is provided with a second connecting gear 210, the first connecting gear 110 is meshed with the second connecting gear 210, the first driving member 510 is a gear structure, the first driving member 510 is meshed with the first connecting gear 110, and when the first housing 100 and the second housing 200 rotate relative to each other, the first connecting gear 110 can drive the first driving member 510 to rotate. Through this structure, the first driving member 510 can be rotated when the first housing 100 and the second housing 200 rotate relative to each other, and then the first transmission member 610 can be driven to slide along the rotating shaft assembly 300 through the cooperation of other structural members of the first driving assembly 500. Therefore, the first transmission member 610 can be driven by the relative rotation of the first housing 100 and the second housing 200, so that the flexible screen assembly 400 can be driven without additionally setting other driving sources.

[0054] In the embodiment of the present application, the flexible screen assembly 400 includes a first support plate 410 and a flexible display screen 420. The first section of the flexible display screen 420 is connected to the first support plate 410. The first support plate 410 is slidably matched with the first shell 100, and the first support plate 410 can move along the first shell 100 in a direction close to or away from the hinge assembly 300.

[0055] The flexible display screen 420 is relatively soft. If the flexible display screen 420 is directly connected to the first shell 100, it is not convenient to drive the flexible display screen 420 on the one hand, and it is easy to cause wear to the flexible display screen 420 on the other hand. In the embodiment of the present application, the flexible display screen 420 of the flexible screen assembly 400 is connected to the first shell 100 through the first support plate 410 of the flexible screen assembly 400. The first support plate 410 and the first shell 100 are slidably matched, and the first support plate 410 drives the movement of the flexible display screen 420, which is convenient for driving the flexible display screen 420 and can avoid wear on the flexible display screen 420. At the same time, when the flexible display screen 420 is operated, the first support plate 410 can provide support for the flexible display screen 420 to avoid deformation of the flexible display screen 420 and extend the service life.

[0056] Optionally, the first shell 100 is provided with a first slide groove 120, and the first support plate 410 is provided in the first slide groove 120. The first support plate 410 slidably cooperates with the first slide groove 120, and the first support plate 410 can move along the first slide groove 120 toward or away from the rotating shaft assembly 300.

[0057] In the embodiment of the present application, the electronic device also includes a first elastic member 710, which is disposed on the first shell 100 and is connected to the second transmission member 620. During the unfolding of the electronic device, the first elastic member 710 can drive the second transmission member 620 to approach or move away from the first transmission member 610.

[0058] During the folding process of the electronic device, the first elastic member 710 is compressed or stretched to store energy. During the unfolding process of the electronic device, the first elastic member 710 returns to its original state and can drive the second transmission member 620 to approach or move away from the first transmission member 610. Therefore, the first elastic member 710 is provided to assist the resetting of the second transmission member 620 during the unfolding process of the electronic device. In addition, if the first elastic member 710 is provided, the first drive assembly 500 and the first transmission assembly 600 only need to realize unidirectional driving, and the reverse driving can be realized by the first elastic member 710. Of course, in the case of providing the first elastic member 710, the first drive assembly 500 and the first transmission assembly 600 can also be bidirectionally driven, and the first elastic member 710 only plays the role of assisting resetting.

[0059] In the embodiment of the present application, the first transmission member 610 is slidably matched with the rotating shaft assembly 300, and the second transmission member 620 is connected to the first section of the flexible screen assembly 400, and when the first transmission member 610 slides along the rotating shaft assembly 300, the second transmission member 620 can be driven to approach or move away from the first transmission member 610, so as to drive the first section of the flexible screen assembly 400 to slide in a direction approaching or moving away from the rotating shaft assembly 300. The first transmission member 610 and the second transmission member 620 can be matched in a variety of ways to achieve that when the first transmission member 610 slides along the rotating shaft assembly 300, the second transmission member 620 can be driven to approach or move away from the first transmission member 610. For example, by bevel matching, cam matching, or connecting rod matching.

[0060] Optionally, one of the first transmission member 610 and the second transmission member 620 is provided with a first protrusion 621, and the other is provided with a first guide groove 611, the extension direction of the first guide groove 611 is oblique to the axial direction of the rotating shaft assembly 300, and the first protrusion 621 is slidably matched with the first guide groove 611.

The second transmission member 620 may also be provided with a first protrusion 621, and the first transmission member 610 may be provided with a first guide groove 611, the extension direction of the first guide groove 611 is oblique to the axial direction of the rotating shaft assembly 300, and the first protrusion 621 is slidably matched with the first guide groove 611.

[0061] In the embodiment of the present application, the second transmission member 620 is provided with a first protrusion 621, and the first transmission member 610 is provided with a first guide groove 611. The extension direction of the first guide groove 611 is oblique to the axial direction of the rotating shaft assembly 300, and the first protrusion 621 is slidably matched with the first guide groove 611.

[0062] In an embodiment of the present application, the electronic device also includes a second transmission assembly 800, and the second transmission assembly 800 includes a third transmission member 810 and a fourth transmission member 820. The third transmission member 810 is slidably matched with the shaft assembly 300, and the fourth transmission member 820 is connected to the second section of the flexible screen assembly 400. In the process of the third transmission member 810 sliding along the shaft assembly 300, the fourth transmission member 820 can drive the fourth transmission member 820 to approach or move away from the third transmission member 810, so as to drive the second section of the flexible screen assembly 400 to move in a direction close to or away from the shaft assembly 300; in the process of folding the electronic device, the first transmission bevel gear 520 or the first transmission member 610 drives the third transmission member 810 to move along the shaft assembly 300, and drives the second section of the flexible screen assembly 400 to move in a direction close to or away from the shaft assembly 300 through the fourth transmission member 820.
