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 with reference to fig. 1 to 12 through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 6, the electronic device according to the present invention 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 600. The first casing 100 and the second casing 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 casing 100 and the second casing 200 are rotatably engaged by the shaft assembly 400, so that the electronic device can be folded or unfolded by the relative rotation of the first casing 100 and the second casing 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 for driving the first transmission member 600 to move along the shaft assembly 400. The drive assembly 500 may be of a wide variety, for example: a screw slider mechanism, a telescopic mechanism, a rack and pinion mechanism, and the like, and the specific type of the driving assembly 500 is not limited to this embodiment.

Referring to fig. 5 and 9, the screen assembly 300 includes a first section and a second section, which are 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. When 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, and the electronic device is unfolded, that is, the electronic device is in an unfolded state. Exemplarily, in a case where the first casing 100 is in the second position with respect to the second casing 200, the first casing 100 and the second casing 200 are folded with each other, that is, the electronic apparatus is in a folded state. In an embodiment, when the first casing 100 is in the second position relative to the second casing 200, a side of the first casing 100 away from the screen assembly 300 is overlapped with a side of the second casing 200 away from the screen assembly 300, thereby realizing the outward folding of the electronic device. In another embodiment, when the first casing 100 is in the second position relative to the second casing 200, a side of the first casing 100 close to the screen assembly 300 is overlapped with a side of the second casing 200 close to the screen assembly 300, thereby realizing the folding-in of the electronic device.

Referring to fig. 5, the first section of the screen assembly 300 is slidably fitted with the first housing 100 so 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 segment of the screen assembly 300, so that the first transmission member 600 can drive the first segment of the screen assembly 300 to move along the first casing 100. Illustratively, one of the first transmission member 600 and the first segment of the screen assembly 300 is provided with a first protrusion 310, the other one is provided with a first guide groove 610, the extending direction of the first guide groove 610 is oblique to the axial direction of the shaft assembly 400, the first protrusion 310 is at least partially positioned in the first guide groove 610, and the first protrusion 310 can move 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 slot 610 through the first protrusion 310 to drive the first section of the screen assembly 300 to move towards or away 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 one side of the first casing 100 and the second casing 200 close to the outer surface, that is, the first section of the screen assembly 300 is disposed on one side of the first casing 100 departing from the second casing 200, and the second section of the screen assembly 300 is disposed on one side of the second casing 200 departing from the first casing 100, so that the electronic device can still display through the screen assembly 300 when the electronic device is folded. The electronic device folded in the present application means that when the electronic device is folded, the screen assembly 300 is located on a side of the first casing 100 and the second casing 200 away from the outer surface, that is, a first section of the screen assembly 300 is disposed on a side of the first casing 100 close to the second casing 200, and a second section of the screen assembly 300 is disposed on a side of the second casing 200 close to the first casing 100. The protective screen assembly 300 can then be folded by the electronic device.

In the above embodiment, in the process of folding the electronic device outward, that is, the first casing 100 rotates towards the side far away from 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 close to the screen assembly 300, so as to prevent the screen assembly 300 from being pulled in the process of folding the electronic device outward, and solve the problem that the screen assembly 300 is easily pulled and damaged in the process of folding the electronic device outward. In the process of folding the electronic device inwards, that is, the first casing 100 rotates towards one side close to the screen assembly 300 relative to the second casing 200, and 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 extruded with each other in the process of folding the electronic device inwards, and the problem that the screen assembly 300 is easily extruded and damaged in the process of folding the electronic device inwards is solved.

Referring to fig. 6 and 8, the first guide groove 610 includes a driving part 611, a first stopper part 612, and a second stopper part 613. Illustratively, the first and second

position limiting portions

612 and 613 are connected to both ends of the driving portion 611, respectively. Referring to fig. 8, the driving portion 611 extends in a direction oblique to the axial direction of the shaft assembly 400, and the first and

second stopper portions

612 and 613 are both disposed in the axial direction of the shaft assembly 400. When the electronic device is in the folded state, the first protrusion 310 is located at the first position-limiting portion 612.

When the electronic device is in the unfolded state, the first protrusion 310 is located at the second position-limiting portion 613. Since the first segment of the screen assembly 300 can slide relative to the first housing 100, the screen assembly 300 may be subjected to forces in various directions during the use of the electronic device, such as: friction generated by the finger during sliding on the surface of the screen assembly 300. In the case where the first section of the screen assembly 300 is applied with a force toward the second section closer to or away from the screen assembly 300 by a frictional force, the force applied to the sidewall of the first guide groove 610 by the first protrusion 310 of the screen assembly 300 is perpendicular to the shaft assembly 400. The first and

second stopper portions

612, 613 are both disposed in the axial direction of the shaft assembly 400, i.e., the side walls of the first and

second stopper portions

612, 613 are disposed in the axial direction of the shaft assembly 400. Therefore, the acting force of the first protrusion 310 on the side wall of the first guide slot 610 is perpendicular to the side walls of the first position-limiting portion 612 and the second position-limiting portion 613, so that the first transmission member 600 can limit the first section of the screen assembly 300 to slide relative to the first casing 100.

In addition, the acting force of the first protrusion 310 on the side wall of the first guiding groove 610 is perpendicular to the side walls of the first limiting portion 612 and the second limiting portion 613, and further the acting force of the first protrusion 310 on the side walls of the first limiting portion 612 and the second limiting portion 613 does not cause the first transmission member 600 to move along the shaft assembly 400. Therefore, the driving assembly 500 does not need to continuously act on the first transmission member 600 in the above-described embodiment, that is, the driving assembly 500 can maintain the stability of the screen assembly 300 when the electronic device is unfolded or folded without consuming energy when the electronic device is unfolded or folded, thereby improving the user experience and prolonging the standby time of the electronic device.

Referring to fig. 5 and 6, the driving assembly 500 includes an electromagnetic coil 510 and a magnetic member 520, and one of the electromagnetic coil 510 and the magnetic member 520 is connected to the shaft assembly 400 and the other is connected to the first transmission member 600. Illustratively, with the electromagnetic coil 510 energized, the electromagnetic coil 510 generates a magnetic field. Therefore, the direction of the magnetic field generated by the electromagnetic coil 510 can be changed by controlling the current passing through the electromagnetic coil 510, so as to generate a force that attracts or repels the magnetic member 520, thereby driving the first transmission member 600 to move along the shaft assembly 400. For example, in the case where electromagnetic coil 510 is disposed on shaft assembly 400 and magnetic member 520 is disposed on first transmission member 600, electromagnetic coil 510 may be fixedly coupled or in limited engagement with shaft assembly 400 to prevent electromagnetic coil 510 from moving along shaft assembly 400. Similarly, in the case that 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 to the shaft assembly 400 or in a position-limited fit 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, under the condition that the magnetic field generated by the electromagnetic coil 510 makes the electromagnetic coil 510 and the magnetic element 520 attract each other, the first transmission element 600 moves toward the direction close to the magnetic element 520, so that the first protrusion 310 can move toward the first position-limiting portion 612 along the first guide groove 610, and further, the first section of the screen assembly 300 is driven to move toward the second section close to the screen assembly 300. Similarly, when the magnetic field generated by the electromagnetic coil 510 makes the electromagnetic coil 510 and the magnetic element 520 repel each other, the first transmission element 600 moves away from the magnetic element 520, so that the first protrusion 310 can move toward the second position-limiting portion 613 along the first guide slot 610, and further the first section of the screen assembly 300 is driven 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 rotating shaft 410, a second rotating shaft 420, and a connector, the first rotating shaft 410 and the second rotating shaft 420 being disposed in parallel, the first rotating shaft 410 being disposed at the first housing 100, the second rotating shaft 420 being disposed at the second rotating shaft 420, the connector having a first mounting hole and a second mounting hole. The first rotating shaft 410 passes through the first mounting hole, and the first housing 100 is rotatably engaged with the connecting member via the first rotating shaft 410. The second rotating shaft 420 passes through the second mounting hole, and the second rotating shaft 420 is rotatably matched with the connecting member 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 casing 100, so that the first casing 100 can rotate around the first rotating shaft 410. Both ends of the second rotating 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 rotating shaft 420.

In the above embodiment, the first rotating shaft 410 and the second rotating shaft 420 are arranged in parallel, so that the first casing 100 and the second casing 200 are divided to rotate around two parallel axes, and a space for the first casing 100 and the second casing 200 to escape from each other is increased, so as to avoid mutual interference between the first casing 100 and the second casing 200 during the unfolding or folding process of the electronic device. Further, the interval between the first and second

rotating shafts

410 and 420 may be adjusted according to the thicknesses of the first and

second housings

100 and 200. Specifically, the larger the distance between the first rotating shaft 410 and the second rotating shaft 420 is, the larger the space formed by the first housing 100 and the second housing 200 at the shaft assembly 400 to escape from each other is. Further, the interval between the first and second

rotating shafts

410 and 420 may be selected according to the thicknesses of the first and

second housings

100 and 200. For this reason, the present application does not limit the interval between the first rotating shaft 410 and the second rotating shaft 420.

In an alternative embodiment, the first rotating shaft 410 and the second rotating shaft 420 are spaced apart by a first distance, and the first rotating shaft 410 is spaced apart from a side of the first section of the first casing 100 away from the screen assembly 300 by a second distance. The second rotating shaft 420 is spaced a third distance from a side of the second housing 200 away from the second section of the screen assembly 300. First distance is not less than second distance and third distance sum, and then is in the circumstances of folding outward at electronic equipment, and first casing 100 and second casing 200 can laminate better to reduce the thickness after the electronic equipment coincide, improve the comfort level after electronic equipment folds.

Referring to fig. 5 to 7, the first end of the first transmission member 600 is rotatably engaged with the first rotating shaft 410, and the first transmission member 600 rotates with the first casing 100 relative to the first rotating shaft 410. One of the first rotating shaft 410 and the first transmission member 600 is provided with a first limiting protrusion 411, and the other one of the first rotating shaft 410 and the first transmission member 600 is provided with a first limiting groove 620, 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 transmission member 600. Specifically, in a case that the electronic device is in an unfolded state, the driving assembly 500 pushes the first transmission member 600 to slide along the first rotating 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 first transmission member 600 to rotate relative to the first rotating shaft 410.

In the above embodiment, the first transmission member 600 is limited by the first limiting protrusion 411 and the first limiting groove 620 to rotate relative to the first rotating shaft 410, and further the first casing 100 is limited by the first rotating shaft 410 to rotate relative to the first rotating shaft 410, so that the stability of the electronic device after being unfolded can be improved, the output of the current of the driving assembly 500 can be retrieved, and the energy consumption of the electronic device can be reduced. 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 coupling member is a magnetic member 520. Illustratively, the connector is made of a magnetic material, such 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, thereby being beneficial to simplifying the internal structure of the electronic device. Illustratively, the coupling member may be a permanent magnet. Or a permanent magnet is embedded in the connecting piece.

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 when the first housing 100 rotates, the first housing 100 drives the second housing 200 to rotate through the first tooth structure 110 and the second tooth structure 210. Through the arrangement of the first tooth structure 110 and the second tooth structure 210, the first shell 100 and the second shell 200 can rotate synchronously, and the user experience is improved. Alternatively, the first tooth structure 110 may be an arc-shaped tooth segment disposed on the first casing 100, and the second tooth structure 210 may be an arc-shaped tooth segment disposed on the second casing 200. Of course, the first tooth structure 110 may also be a gear fixedly disposed on the first casing 100, and the second tooth structure 210 may be a gear fixedly disposed on the second casing 200. Referring to fig. 6, each of the first and

second housings

100 and 200 is exemplarily provided with a torsion bar, the first tooth structure 110 is provided on the torsion bar of the first housing 100, and the second tooth structure 210 is provided on the torsion bar of the second housing 200.

In an alternative embodiment, the electronic device includes a rotation limiting member 900, and the rotation limiting member 900 is disposed on the first rotating shaft 410 and/or the second rotating shaft 420, so as to limit the inward folding of the electronic device through the rotation limiting member 900. For example, the rotation limiting member 900 has a fixing portion and a limiting portion, the fixing portion is perpendicular to the 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 a side of the first casing 100 and the second casing 200 close to the display surface of the screen assembly 300. When the electronic device is unfolded, the limiting portions respectively abut against the first casing 100 and the second casing 200 on the side close to the display surface of the screen assembly 300, so as to prevent the electronic device from being folded inwards. In an alternative embodiment, the first rotating shaft 410 and the second rotating shaft 420 may be connected through a rotation limiting member 900, that is, the rotation limiting member 900 may be a connecting member connecting the first rotating shaft 410 and the second rotating shaft 420.

Referring to fig. 5 and 6, the electronic device further includes a second transmission member 700, the second section of the screen assembly 300 is slidably engaged with the second housing 200, one of the second transmission member 700 and the second section of the screen assembly 300 is provided with a second protrusion 320, the other is provided with a second guide groove 710, the extending direction of the second guide groove 710 is oblique to the axial direction of the shaft assembly 400, the second protrusion 320 is at least partially located in the second guide groove 710, and the second protrusion 320 is movable along the second guide groove 710. During the folding process of the electronic device, the driving component 500 drives the second transmission component 700 to move along the shaft component 400, and the second transmission component 700 slides along the second guide groove 710 through the second protrusion 320 to drive the second section of the screen component 300 to move towards or away from the first section of the screen component 300.

It should be noted that the connection structure of the second transmission member 700 and the second section of the screen assembly 300 described in 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 between the second transmission member 700 and the second section of the screen assembly 300 will not be further described in the embodiments of the present application. The second transmission member 700 and the axle assembly 400 are coupled in the same manner as the first transmission member 600 and the axle assembly 400. Exemplarily, 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.
