It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The electronic device provided by the embodiment of the application is described in detail below with reference to fig. 1 to 12 through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 6, the electronic apparatus according to the present application includes a first housing 100, a second housing 200, a screen assembly 300, a shaft assembly 400, a driving assembly 500, and a first transmission member 600. The first housing 100 and the second housing 200 are basic structural members, and can provide a mounting base for each component in the electronic device.

Referring to fig. 1, 2 and 5, the first and second housings 100 and 200 are rotatably coupled by the shaft assembly 400, so that the electronic device can be folded or unfolded by the relative rotation of the first and second housings 100 and 200.

Referring to fig. 5 and 6, the first transmission member 600 is slidably engaged with the shaft assembly 400, and the driving assembly 500 is used to drive the first transmission member 600 to move along the shaft assembly 400. There are many kinds of driving assembly 500, for example: a screw slider mechanism, a telescopic mechanism, a rack and pinion mechanism, etc., and the specific kind of the driving assembly 500 is not limited to this embodiment.

Referring to fig. 5 and 9, the screen assembly 300 includes a first segment and a second segment, the first segment and the second segment being connected. Illustratively, a first section of the screen assembly 300 is disposed in the first housing 100 and a second section of the screen assembly 300 is disposed in the second housing 200. Illustratively, the first housing 100 is rotatable relative to the second housing 200 between a first position and a second position. In the case that the first housing 100 is at the first position relative to the second housing 200, the display surfaces of the screen assemblies 300 are located on the same plane, so that the electronic device is unfolded, that is, the electronic device is in an unfolded state. Illustratively, with the first housing 100 in the second position relative to the second housing 200, the first housing 100 and the second housing 200 are folded with respect to each other, i.e., the electronic device is in a folded state. In an embodiment, when the first housing 100 is at the second position relative to the second housing 200, a side of the first housing 100 away from the screen assembly 300 is stacked on a side of the second housing 200 away from the screen assembly 300, so as to realize the folding-out of the electronic device. In another embodiment, when the first housing 100 is at the second position relative to the second housing 200, a side of the first housing 100 close to the screen assembly 300 is stacked on a side of the second housing 200 close to the screen assembly 300, so as to realize the folding-in of the electronic device.

Referring to fig. 5, the first section of the screen assembly 300 is slidably engaged with the first housing 100 such that the first section of the screen assembly 300 can slide along the first housing 100. Referring to fig. 5, the first transmission member 600 is connected to the first section of the screen assembly 300 such that the first transmission member 600 can move the first section of the screen assembly 300 along the first housing 100. Illustratively, one of the first transmission member 600 and the first section of the screen assembly 300 is provided with the first protrusion 310, the other is provided with the first guide groove 610, the extending direction of the first guide groove 610 is inclined to the axial direction of the shaft assembly 400, the first protrusion 310 is at least partially located in the first guide groove 610, and the first protrusion 310 is movable along the first guide groove 610. During the folding process of the electronic device, the driving assembly 500 drives the first transmission member 600 to move along the shaft assembly 400, and the first transmission member 600 slides along the first guide groove 610 through the first protrusion 310 to drive the first section of the screen assembly 300 to move in a direction approaching or separating from the second section of the screen assembly 300.

It should be noted that, when the electronic device is folded, the screen assembly 300 is located on a side, close to the outer surface, of the first housing 100 and the second housing 200, that is, the first section of the screen assembly 300 is disposed on a side, away from the second housing 200, of the first housing 100, and the second section of the screen assembly 300 is disposed on a side, away from the first housing 100, of the second housing 200, so that the electronic device can still be displayed through the screen assembly 300 when the electronic device is in a folded state. The electronic device described in the present specification means that, when the electronic device is in a folded state, the screen assembly 300 is located on a side of the first housing 100 and the second housing 200 away from the outer surface, that is, the first section of the screen assembly 300 is disposed on a side of the first housing 100 close to the second housing 200, and the second section of the screen assembly 300 is disposed on a side of the second housing 200 close to the first housing 100. And the protective screen assembly 300 may be folded through the electronic device.

In the above embodiment, in the process of folding the electronic device, that is, the first housing 100 rotates relative to the second housing 200 to a side far away from the screen assembly 300, the first transmission member 600 drives the first section of the screen assembly 300 to move to the second section close to the screen assembly 300, so as to avoid the screen assembly 300 from being pulled in the process of folding the electronic device, and solve the problem that the screen assembly 300 is easily damaged due to being pulled in the process of folding the electronic device. In the folding process of the electronic device, that is, the first casing 100 rotates towards the side close to the screen assembly 300 relative to the second casing 200, the first transmission member 600 drives the first section of the screen assembly 300 to move towards the second section far away from the screen assembly 300, so that the first section and the second section of the screen assembly 300 are prevented from being mutually extruded in the folding process of the electronic device, and the problem that the screen assembly 300 is easy to be extruded and damaged in the folding process of the electronic device is solved.

Referring to fig. 6 and 8, the first guide groove 610 includes a driving part 611, a first limiting part 612, and a second limiting part 613. Illustratively, the first and second limiting portions 612 and 613 are respectively connected to both ends of the driving portion 611. Referring to fig. 8, the extending direction of the driving part 611 is inclined to the axial direction of the shaft assembly 400, and the first and second limiting parts 612 and 613 are disposed along the axial direction of the shaft assembly 400. In the case that the electronic device is in the folded state, the first protrusion 310 is located at the first limiting portion 612.

The first protrusion 310 is located at the second limiting portion 613 when the electronic device is in the unfolded state. Since the first section of the screen assembly 300 may slide relative to the first housing 100, the screen assembly 300 may be subjected to forces in various directions during use of the electronic device, such as: the friction force generated by the fingers during the sliding of the surface of the screen assembly 300. In the case where the first section of the screen assembly 300 receives a frictional force toward or away from the second section of the screen assembly 300, the force of the first protrusion 310 of the screen assembly 300 acting on the sidewall of the first guide groove 610 is perpendicular to the shaft assembly 400. The first limiting portion 612 and the second limiting portion 613 are both disposed along the axial direction of the shaft assembly 400, that is, the sidewalls of the first limiting portion 612 and the second limiting portion 613 are disposed along the axial direction of the shaft assembly 400. Therefore, the force of the first protrusion 310 acting on the sidewall of the first guide groove 610 is perpendicular to the sidewalls of the first and second limiting portions 612 and 613, so that the first transmission member 600 can limit the first section of the screen assembly 300 to slide relative to the first housing 100.

In addition, the force of the first protrusion 310 acting on the side wall of the first guide groove 610 is perpendicular to the side walls of the first and second limiting portions 612 and 613, and thus the force of the first protrusion 310 acting on the side walls of the first and second limiting portions 612 and 613 does not move the first transmission member 600 along the shaft assembly 400. Therefore, in the above embodiment, the driving assembly 500 does not need to continuously act on the first transmission member 600, that is, the driving assembly 500 can maintain the stability of the screen assembly 300 under the condition that the electronic device is unfolded or folded without consuming energy under the condition that the electronic device is unfolded or folded, so that the user experience is improved, and the standby time of the electronic device is prolonged.

Referring to fig. 5 and 6, the driving assembly 500 includes a solenoid 510 and a magnetic member 520, one of the solenoid 510 and the magnetic member 520 being connected to the shaft assembly 400, and the other being connected to the first transmission member 600. Illustratively, when the electromagnetic coil 510 is energized, the electromagnetic coil 510 generates a magnetic field. The direction of the magnetic field generated by the electromagnetic coil 510 can be changed by controlling the current through the electromagnetic coil 510, thereby generating a force that attracts or repels the magnetic member 520 to drive the first transmission member 600 along the shaft assembly 400. For example, in the case that the electromagnetic coil 510 is disposed on the shaft assembly 400 and the magnetic member 520 is disposed on the first transmission member 600, the electromagnetic coil 510 may be fixedly connected or in a limited fit with the shaft assembly 400 to prevent the electromagnetic coil 510 from moving along the shaft assembly 400. Similarly, in the case where the magnetic member 520 is disposed on the shaft assembly 400 and the electromagnetic coil 510 is disposed on the first transmission member 600, the magnetic member 520 may be fixedly connected or in a limited fit with the shaft assembly 400, so as to prevent the electromagnetic coil 510 from moving along the shaft assembly 400.

Referring to fig. 5 to 8, in an alternative embodiment, the electromagnetic coil 510 may be disposed on the first transmission member 600, and the magnetic member 520 may be disposed on the shaft assembly 400. For example, when the magnetic field generated by the electromagnetic coil 510 makes the electromagnetic coil 510 and the magnetic member 520 attract each other, the first transmission member 600 moves toward the magnetic member 520, so that the first protrusion 310 can move along the first guiding groove 610 toward the first limiting portion 612, and further drive the first section of the screen assembly 300 to move toward the second section of the screen assembly 300. Similarly, when the magnetic field generated by the electromagnetic coil 510 makes the electromagnetic coil 510 repel the magnetic member 520, the first transmission member 600 moves away from the magnetic member 520, so that the first protrusion 310 can move along the first guiding groove 610 toward the second limiting portion 613, and further drive the first section of the screen assembly 300 to move toward the second section away from the screen assembly 300.

Referring to fig. 5 and 6, the shaft assembly 400 may include a first shaft 410, a second shaft 420, and a connection member having a first mounting hole and a second mounting hole, the first shaft 410 and the second shaft 420 being disposed in parallel, the first shaft 410 being disposed in the first housing 100, the second shaft 420 being disposed in the second shaft 420. The first shaft 410 passes through the first mounting hole, and the first housing 100 is rotatably coupled with the connection member through the first shaft 410. The second rotating shaft 420 passes through the second mounting hole, and the second rotating shaft 420 is in running fit with the connecting piece through the second rotating shaft 420. Illustratively, both ends of the first rotating shaft 410 are respectively rotatably engaged with both sides of the first housing 100, so that the first housing 100 can rotate around the first rotating shaft 410. Both ends of the second rotation shaft 420 are respectively rotatably engaged with both sides of the second housing 200, so that the second housing 200 can rotate around the second rotation shaft 420.

In the above embodiment, the first rotation shaft 410 and the second rotation shaft 420 are disposed in parallel, so that the first housing 100 and the second housing 200 are separated to rotate around two parallel axes, and the space for avoiding the first housing 100 and the second housing 200 from each other is increased, so as to avoid mutual interference of the first housing 100 and the second housing 200 in the unfolding or folding process of the electronic device. Further, the interval between the first and second rotation shafts 410 and 420 may be adjusted according to the thickness of the first and second housings 100 and 200. Specifically, the larger the interval between the first and second rotation shafts 410 and 420, the larger the space formed by the first and second housings 100 and 200 at the shaft assembly 400 to be escaped from each other. Further, the interval between the first rotation shaft 410 and the second rotation shaft 420 may be selected according to the thickness of the first and second cases 100 and 200. For this reason, the present application does not limit the interval between the first rotation shaft 410 and the second rotation shaft 420.

In an alternative embodiment, the first rotation axis 410 is spaced apart from the second rotation axis 420 by a first distance, and the first rotation axis 410 is spaced apart from a side of the first housing 100 away from the first section of the screen assembly 300 by a second distance. The second rotation shaft 420 is a third distance from a side of the second housing 200 remote from the second section of the screen assembly 300. The first distance is not smaller than the sum of the second distance and the third distance, and then under the condition that the electronic equipment is folded outwards, the first shell 100 and the second shell 200 can be attached better, so that the thickness of the electronic equipment after being folded is reduced, and the comfort of the electronic equipment after being folded is improved.

Referring to fig. 5 to 7, a first end of the first transmission member 600 is rotatably coupled to the first shaft 410, and the first transmission member 600 rotates with the first housing 100 relative to the first shaft 410. One of the first rotating shaft 410 and the first transmission member 600 is provided with a first limiting protrusion 411, the other one is provided with a first limiting groove 620, and when the electronic device is in the unfolded state, the first limiting protrusion 411 is at least partially located in the first limiting groove 620, and the first limiting protrusion 411 and the first limiting groove 620 limit the first transmission member 600 to rotate relative to the first rotating shaft 410. For example, the first limiting protrusion 411 may be disposed on the first rotating shaft 410, and the first limiting groove 620 is disposed on the first driving member 600. Specifically, when the electronic device is in the unfolded state, the driving assembly 500 pushes the first transmission member 600 to slide along the first rotation shaft 410, so that the first limiting protrusion 411 is at least partially embedded into the first limiting groove 620, so as to limit the rotation of the first transmission member 600 relative to the first rotation shaft 410.

In the above embodiment, the first limiting protrusion 411 and the first limiting groove 620 limit the rotation of the first transmission member 600 relative to the first rotation shaft 410, so that the rotation of the first housing 100 relative to the first rotation shaft 410 can be limited by the first rotation shaft 410, which can improve the stability of the electronic device after being unfolded, retrieve the current output of the driving assembly 500, and reduce the energy consumption of the electronic device. In the case that the electronic device is a mobile terminal, the above scheme is beneficial to prolonging the standby time of the electronic device.

In an alternative embodiment, the connector is a magnetic member 520. Illustratively, the connector is made of a magnetic material so that the connector can generate a magnetic field that interacts with the electromagnetic coil 510. In this embodiment, the material of the connecting member is set to be a magnetic material, so that the connecting member can also be used as the magnetic member 520, which is beneficial to simplifying the internal structure of the electronic device. The connection element may be a permanent magnet, for example. Or the connecting piece is embedded with a permanent magnet.

Referring to fig. 5, the first housing 100 is provided with a first tooth structure 110, the second housing 200 is provided with a second tooth structure 210, the first tooth structure 110 is engaged with the second tooth structure 210, and the first housing 100 drives the second housing 200 to rotate through the first tooth structure 110 and the second tooth structure 210 in the case that the first housing 100 rotates. By providing the first tooth structure 110 and the second tooth structure 210, the first housing 100 and the second housing 200 can be rotated synchronously, and user experience is improved. Alternatively, the first tooth structure 110 may be an arc-shaped tooth segment disposed on the first housing 100, and the second tooth structure 210 may be an arc-shaped tooth segment disposed on the second housing 200. Of course, the first tooth structure 110 may also be a gear fixedly disposed on the first housing 100, and the second tooth structure 210 may be a gear fixedly disposed on the second housing 200. Referring to fig. 6, exemplarily, the first housing 100 and the second housing 200 are each provided with a torsion bar, the first tooth structure 110 is disposed on the torsion bar located at the first housing 100, and the second tooth structure 210 is disposed on the torsion bar located at the second housing 200.

In an alternative embodiment, the electronic device includes a rotation limiter 900, where the rotation limiter 900 is disposed on the first rotation shaft 410 and/or the second rotation shaft 420, so as to limit the electronic device from being folded inwards by the rotation limiter 900. Illustratively, the rotation limiter 900 has a fixing portion and a limiting portion, wherein the fixing portion is fixed on the first rotating shaft 410 and/or the second rotating shaft 420, and the limiting portion is bent toward one side of the first housing 100 and the second housing 200 near the display surface of the screen assembly 300. In addition, when the electronic device is unfolded, the limiting portions are respectively abutted against one side of the first housing 100 and one side of the second housing 200, which are close to the display surface of the screen assembly 300, so that the electronic device is prevented from being folded inwards. In an alternative embodiment, the first shaft 410 and the second shaft 420 may be connected by a rotation limiter 900, i.e. the rotation limiter 900 may be a connection connecting the first shaft 410 and the second shaft 420.

During the folding process of the electronic device, the driving assembly 500 drives the second transmission member 700 to move along the shaft assembly 400, and the second transmission member 700 slides along the second guide groove 710 through the second protrusion 320 to drive the second section of the screen assembly 300 to move in a direction approaching or separating from the first section of the screen assembly 300.

It should be noted that, the connection structure of the second transmission member 700 and the second section of the screen assembly 300 according to the present application is the same as the connection structure of the first transmission member 600 and the second section of the screen assembly 300. For this reason, the connection structure of the second transmission member 700 and the second section of the screen assembly 300 will not be further described in the embodiment of the present application. The second transmission member 700 and the shaft assembly 400 are coupled in the same manner as the first transmission member 600 and the shaft assembly 400. The second transmission member 700 has a second limiting groove 720, and the second rotating shaft 420 is provided with a second limiting protrusion 421. Under the condition that the electronic equipment is in the unfolding state, the second limiting protrusion 421 is at least partially located in the second limiting groove 720, so that the second limiting protrusion 421 and the second limiting groove 720 are in limiting fit, and further the second transmission member 700 and the second rotating shaft 420 can limit the second transmission member 700 to rotate relative to the second rotating shaft 420 through the limiting fit of the second limiting groove 720 and the second limiting protrusion 421.
