For example, when the folding electronic device is folded, the bending radius at the hinge is small, which easily causes the flexible screen to be excessively pressed to be folded or damaged. When the folding electronic device is folded outwards, the bending radius of the hinge is too large, so that the flexible screen is easily excessively pulled and deformed, and even the flexible screen is broken. Therefore, the current folding electronic device has the problem that the flexible screen is easily damaged in the folding process, and finally the service life of the flexible screen is short.

The electronic device provided by the embodiment of the present application is described in detail with reference to fig. 1 to 10 through specific embodiments and application scenarios thereof.

The electronic device of the present invention includes a first housing 100, a second housing 200, a screen assembly 300, a shaft assembly 400, and a link mechanism 500. The first and

second housings

100 and 200 are basic structural members, and may provide a mounting base for each component of the electronic device.

Referring to fig. 1 to 6, the first housing 100 and the second housing 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 housing 100 and the second housing 200.

Referring to fig. 3 and 4, the screen assembly 300 covers one side surfaces of the first and

second housings

100 and 200. Illustratively, the screen assembly 300 includes a first segment, a second segment, and a connecting segment, the connecting segment being located between the first segment and the second segment, and the connecting segment being connected to the first segment and the second segment, respectively. The first section is disposed on the first casing 100, and the second section is disposed on the second casing 200. Illustratively, the connecting segment of screen assembly 300 is opposite shaft assembly 400.

Illustratively, the first housing 100 is rotatable relative to the second housing 200 between a first position and a second position. Referring to fig. 3 and 4, in a case where the first casing 100 is at the first position relative to the second casing 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. Referring to fig. 2 and 5, 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. Illustratively, in a folded state of the electronic device, 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 inward folding of the electronic device.

Referring to fig. 2 to 5, the link mechanism 500 includes a first link 510 and a second link 520, the first link 510 and the second link 520 are disposed to intersect, and the first link 510 and the second link 520 are rotatably engaged at an intersection 511. The first end of the first link 510 is connected to the first casing 100, the first end of the second link 520 is connected to the second casing 200, and the second end of the first link 510 and the second end of the second link 520 are supported by the screen assembly 300. During the folding process of the electronic device, the first casing 100 and the second casing 200 drive the first link 510 and the second link 520 to rotate relatively, the second end of the first link 510 and the second end of the second link 520 are away from each other, and the screen assembly 300 is at least partially recessed in a gap between the second end of the first link 510 and the second end of the second link 520.

In the above embodiment, in the process of folding the electronic device, the first casing 100 and the second casing 200 can respectively drive the first link 510 and the second link 520 to rotate. Also, a gap assembly formed between the second end of the first link 510 and the second end of the second link 520 is increased so that the redundant portion of the screen assembly 300 can be accommodated in the gap formed between the second end of the first link 510 and the second end of the second link 520. Therefore, the electronic device according to the above embodiment can prevent the screen assembly 300 from being pressed during the folding process of the electronic device, and prevent the screen assembly 300 from being damaged by pressing.

Referring to fig. 4 and 5, during deployment of the electronic device, the first link 510 and the second link 520 rotate relative to each other and support a side of the screen assembly 300 close to the shaft assembly 400, so that a portion of the screen assembly 300 opposite to the shaft assembly 400 can move away from the shaft assembly 400 to assist in deployment of the screen assembly 300.

In the above embodiment, the first link 510 and the second link 520 form the gap for accommodating the redundant portion of the screen assembly 300, so that the radius of the bent portion of the screen assembly 300 after being bent can be increased, and the crease of the bent portion of the screen assembly 300 can be eliminated or weakened. And the first link 510 and the second link 520 may support the screen assembly 300 and assist the screen assembly 300 to be unfolded during the unfolding of the electronic device.

Referring to fig. 2 to 5, the first housing 100, the second housing 200 and the shaft assembly 400 form a receiving groove 600 along the shaft assembly 400 at a side of the shaft assembly 400 adjacent to the screen assembly 300. In the unfolded state of the electronic device, the second end of the first link 510 and the second end of the second link 520 are at least partially located in the receiving groove 600, and the second end of the first link 510 and the second end of the second link 520 are supported at a portion of the screen assembly 300 opposite to the receiving groove 600.

Referring to fig. 4 and 5, during the unfolding process of the electronic device, the first housing 100 and the second housing 200 rotate relatively, and the first link 510 and the second link 520 are driven to rotate relatively. During the relative rotation of the first link 510 and the second link 520, the second end of the first link 510 and the second end of the second link 520 approach each other, that is, the included angle between the second end of the first link 510 and the second end of the second link 520 is reduced, and at the same time, the first casing 100 and the second casing 200 can pull the redundant portion of the screen assembly 300, so that the redundant portion of the screen assembly 300 trapped in the gap between the second end of the first link 510 and the second end of the second link 520 can be gradually expanded. In a fully unfolded state of the electronic device, a portion of the screen assembly 300 opposite to the shaft assembly 400 may be supported by the first link 510 and the second link 520 to prevent the screen assembly 300 from being invaginated in the receiving groove 600.

Referring to fig. 9 and 10, the link mechanism 500 further includes a first support 570 and a second support 580, the first support 570 being connected to the second end of the first link 510, and the second support 580 being connected to the second end of the second link 520. In the unfolded state of the electronic device, the first and

second supports

570 and 580 are supported at portions of the screen assembly 300 opposite to the receiving groove 600.

Illustratively, the first and

second supports

570 and 580 may be support plates. During the unfolding process of the electronic device, the first link 510 and the second link 520 rotate relatively, and thus the first support 570 and the second support 580 rotate. Further, in a case where the electronic device is unfolded, each of the first and

second supports

570 and 580 may be flush with a side of the first and/or

second cases

100 and 200 close to the screen assembly 300, so that the first and

second supports

570 and 580 may support the screen assembly 300.

In the above embodiment, the first support 570 and the second support 580 may support a portion of the screen assembly 300 opposite to the receiving groove 600 when the electronic device is unfolded, so as to prevent the screen assembly 300 from being depressed during use, and improve user experience.

Referring to fig. 4 and 5, the distance of the intersection 511 from the first end of the first link 510 is a first distance, the distance of the intersection 511 from the second end of the first link 510 is a second distance, and the first distance is greater than the second distance. The distance of the intersection 511 from the first end of the second link 520 is a third distance, the distance of the intersection 511 from the second end of the second link 520 is a fourth distance, and the third distance is greater than the fourth distance. In the process of relative rotation of the first link 510 and the second link 520, the first distance is greater than the second distance, and the third distance is greater than the fourth distance, so that the resistance of the first shell 100 and the second shell 200 to drive the first link 510 and the second link 520 to rotate can be effectively reduced, and the folding or unfolding process of the electronic device is smoother.

In an alternative embodiment, the first distance is equal to the third distance, and the second distance is equal to the fourth distance. Illustratively, the first link 510 and the second link 520 are symmetrically disposed. The first link 510 and the second link 520 may be straight rods or curved rods. For example, the second end of the first link 510 and the second end of the second link 520 may each be provided with a support portion to support a side of the first support 570 and the second support 580 away from the screen assembly 300 through the support portions.

Referring to fig. 6 to 8, the link mechanism 500 includes a first elastic member 530 and a second elastic member 540, and the first elastic member 530 is disposed between the second end of the first link 510 and the second end of the second link 520 and extends in the extending direction of the screen assembly 300. The second elastic member 540 is disposed between the first elastic member 530 and the intersection 511, and extends in a direction perpendicular to the screen assembly 300. During the unfolding of the electronic device, the first elastic member 530 is gradually contracted, and the second elastic member 540 is gradually extended. During the folding process of the electronic device, the first elastic member 530 is gradually extended and the second elastic member 540 is gradually contracted. Illustratively, the first elastic member 530 and the second elastic member 540 are both coil springs.

Referring to fig. 4, in the unfolded state of the electronic device, the first elastic member 530 is in a compressed state, so that the first elastic member 530 is not easily bent. During the folding process of the electronic device, the first elastic member 530 is stretched, so that the first elastic member 530 protrudes toward the gap between the first link 510 and the second link 520 under the pulling of the second elastic member 540, thereby forming a groove for accommodating a redundant portion of the screen assembly 300.

During the unfolding process of the electronic device, the first elastic member 530 contracts, so that the bending resistance of the first elastic member 530 is increased, and the second elastic member 540 is pulled to extend, the depth of the groove formed by the first elastic member 530 for accommodating the redundant portion of the screen assembly 300 is reduced, so that the screen assembly 300 located in the gap between the first link 510 and the second link 520 is pushed to move away from the intersection 511.

In the above embodiment, the first elastic member 530 and the second elastic member 540 may assist the screen assembly 300 in the gap between the first link 510 and the second link 520 to be extended outward.

Referring to fig. 4 to 10, the shaft assembly 400 includes a first rotating shaft 410, a second rotating shaft 420, and a connecting member 430, the first rotating shaft 410 and the second rotating shaft 420 are disposed in parallel, and the first rotating shaft 410 and the second rotating shaft 420 are connected by the connecting member 430. The first rotation shaft 410 is connected to the first casing 100, and the second rotation shaft 420 is connected to the second casing 200. Illustratively, the connecting member 430 is provided with a first mounting hole and a second mounting hole, and the first mounting hole and the second mounting hole are arranged in parallel. Further, the first rotating shaft 410 is disposed in the first mounting hole and is rotatably engaged with the first mounting hole; the second shaft 420 is disposed in the second mounting hole and is rotatably engaged with the second mounting hole.

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 respectively 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 prevent the first casing 100 and the second casing 200 from interfering with each other during the process of unfolding or folding 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, it is necessary to select a distance between the first rotating shaft 410 and the second rotating shaft 420 according to thicknesses of the first housing 100 and the second housing 200. For this reason, the embodiment 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 fifth 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 sixth distance. The second rotating shaft 420 is spaced apart from a side of the second section of the second housing 200 away from the screen assembly 300 by a seventh distance. The fifth distance is not less than the sum of the sixth distance and the seventh distance, and then under the condition that the electronic device is folded outwards, the first shell 100 and the second shell 200 can be better attached to reduce the thickness of the electronic device after being folded, and the comfort level of the electronic device after being folded is improved.

Referring to fig. 4 to 10, the first end of the first link 510 is rotatably coupled to the first housing 100, and the first end of the first link 510 is eccentrically disposed with respect to the first rotation shaft 410. The first end of the second link 520 is rotatably connected to the second housing 200, and the first end of the second link 520 is eccentrically disposed with respect to the second rotation shaft 420.

It should be noted that the first end of the first link 510 is eccentrically disposed with respect to the first rotation shaft 410, which means that the center of rotation of the first link 510 with respect to the first casing 100 does not coincide with the center of rotation of the first casing 100 with respect to the first rotation shaft 410. Similarly, the first end of the second link 520 is eccentrically disposed with respect to the second rotating shaft 420, which means that the center of the second link 520 rotating with respect to the second housing 200 does not coincide with the center of the second housing 200 rotating with respect to the second rotating shaft 420.

Illustratively, in a case where the electronic apparatus is unfolded, a connection point of the first housing 100 and the first link 510 is an eighth distance from the second housing 200. In a case where the electronic apparatus is folded, a distance from the connection point of the first housing 100 and the first link 510 to the second housing 200 is a ninth distance, and the eighth distance is less than the ninth distance. Further, in a case where the electronic apparatus is unfolded, a distance from the first casing 100 at a connection of the second casing 200 and the second link 520 is a tenth distance. In a case where the electronic apparatus is folded, a distance from the first casing 100 at a junction of the second casing 200 and the second link 520 is an eleventh distance, and the tenth distance is smaller than the eleventh distance.

In the process of folding the electronic device, the first housing 100 rotates relative to the first rotating shaft 410, and the second housing 200 rotates relative to the second rotating shaft 420, so as to drive the first end of the first link 510 and the first end of the second link 520 to move away from each other. During the unfolding process of the electronic device, the first housing 100 rotates relative to the first rotating shaft 410, and the second housing 200 rotates relative to the second rotating shaft 420, so as to drive the first end of the first link 510 and the first end of the second link 520 to approach each other.

It should be noted that the first end of the first link 510 is rotatably connected to the first casing 100, the first end of the first link 510 may be directly rotatably engaged with the first casing 100, or the first end of the first link 510 may be indirectly rotatably engaged with the first casing 100.

In an alternative embodiment, the first housing 100 and the first link 510 are provided with hinge holes, so that the first housing 100 and the first link 510 can be coupled to each other by pivoting.

In another alternative embodiment, the link mechanism 500 further includes a third link 550, the third link 550 is connected to the first housing 100 and/or the first rotating shaft 410, the third link 550 is rotatable with the first housing 100 about the first rotating shaft 410, and the second end of the first link 510 is rotatably connected to the third link 550. Alternatively, the third link 550 may be fixedly connected to the first shaft 410 and/or the first housing 100. For example, during the folding process of the electronic device, the third link 550 is driven by the first casing 100 and/or the first rotating shaft 410 to rotate around the first rotating shaft 410, and then the first end of the first link 510 is driven to move away from the second casing 200.

Similarly, the link mechanism 500 further includes a fourth link 560, the fourth link 560 is connected to the second housing 200 and/or the second rotating shaft 420, the fourth link 560 is rotatable around the second rotating shaft 420 with the second housing 200, and a second end of the second link 520 is rotatably connected to the fourth link 560. Alternatively, the fitting relationship of the second link 520 with the second housing 200 is the same as that between the first link 510 and the first housing 100. For this reason, the description will not further describe the fitting relationship of the second link 520 and the second housing 200.

Referring to fig. 5, 7 and 8, a guide 431 is formed on the connecting member 430, and the guide 431 is formed from a side of the connecting member 430 close to the screen assembly 300 to a side of the connecting member 430 far from the screen assembly 300. The cross portion 511 is slidably fitted with the rail 431, and the cross portion 511 is movable along the rail 431. Illustratively, the guide rail 431 is a guide groove provided on the connecting member 430, the intersection portion 511 is at least partially located in the guide groove, and the intersection portion 511 can slide along the guide groove.

In an alternative embodiment, the first link 510 and the second link 520 are rotatably coupled by a coupling shaft. Illustratively, the connecting shaft at least partially protrudes from the first link 510 and/or the second link 520, and the connecting shaft protruding from the first link 510 and/or the second link 520 is at least partially located in the guide groove, so that the intersection 511 of the first link 510 and the second link 520 can be slidably engaged with the guide groove through the connecting shaft.

In the above embodiment, in the folding process of the electronic device, the first casing 100 and the second casing 200 rotate relatively, and drive the first link 510 and the second link 520 to move in the direction away from the screen assembly 300. In the unfolding process of the electronic device, the first casing 100 and the second casing 200 rotate relatively, and the first link 510 and the second link 520 are driven to move towards the screen assembly 300. This scheme can move in a direction away from the screen assembly 300 by the first link 510 and the second link 520, so that the electronic device can form a larger space to accommodate the redundant portion of the screen assembly 300 in the folded state.

In an alternative embodiment, the electronic device includes a first gear and a second gear, the first gear and the second gear being in mesh. The first gear is connected to the first housing 100, and the first housing 100 can drive the first gear to rotate relative to the connecting member 430. The second gear is connected to the second housing 200, and the second housing 200 can drive the second gear to rotate relative to the connecting member 430. For example, the first and second gears may be arcuate gear segments. For example, the first gear may be fixedly disposed on the first housing 100, and the second gear may be fixedly disposed on the second housing 200. The first gear and the second gear are meshed, so that the first casing 100 and the second casing 200 can rotate synchronously, and the user experience is improved.

Referring to fig. 4 and 5, the screen assembly 300 includes a flexible screen 310 and a flexible support 320, the flexible support 320 is disposed on a side of the flexible screen 310 away from the display surface, and the flexible support 320 is opposite to the shaft assembly 400. Alternatively, both sides of the flexible support 320 may be connected to the first and

second housings

100 and 200, respectively. In this embodiment, the flexible support 320 may prevent the link mechanism 500 from being directly supported on the flexible screen 310, so as to protect the flexible screen 310.

The electronic device disclosed in the embodiment of the application can be a mobile phone, a watch, a vehicle-mounted display, a tablet computer, an electronic book reader, a medical apparatus and the like, and the embodiment of the application does not limit the specific type of the electronic device.
