Background
With the development of technology, the development of electronic devices is faster and faster, and meanwhile, the requirements of users on the electronic devices are higher and higher. At present, flexible screens are also widely applied to electronic devices, so as to form folding electronic devices.
Folding electronic devices often present folding problems during folding. For example, when a foldable electronic device is folded inwards, because the bending radius at the hinge is smaller, the flexible screen is more easily extruded to cause crease or damage. When the foldable electronic equipment is folded outwards, the bending radius at the hinge is too large, so that the flexible screen is easily pulled and deformed excessively, and even the flexible screen is broken. As can be seen, the current folding electronic device has a problem that the flexible screen is easily damaged during the folding process, which ultimately results in a shorter service life of the flexible screen.

in the folding process of the electronic equipment, the second end of the connecting rod mechanism rotates relative to the shaft assembly, and the connecting rod mechanism moves through the cooperation of the guide surface and the pushing part to drive the first display screen to move along the direction of the first equipment main body to approach the shaft assembly;
in the unfolding process of the electronic equipment, the second end of the connecting rod mechanism rotates relative to the shaft assembly, and the connecting rod mechanism moves through the cooperation of the guide surface and the pushing part to drive the first display screen to move along the first equipment main body in the direction away from the shaft assembly.
The technical scheme adopted by the invention can achieve the following beneficial effects:
in the electronic device disclosed by the embodiment of the invention, the first device main body and the second device main body are in running fit through the shaft assembly, so that the first device main body and the second device main body can rotate relatively, and the first device main body and the second device main body can be unfolded and folded. In the process of relative rotation of the first equipment main body and the second equipment main body, the pushing part slides along the guide surface, and then the second end of the connecting rod mechanism is driven to move along the rotating shaft. The second end of the connecting rod mechanism drives the first display screen to move towards a direction approaching or separating from the shaft assembly in the moving process. Therefore, the flexible display screen can be prevented from being damaged by being pulled or extruded in the folding process of the electronic equipment, the purpose of protecting the flexible display screen is achieved, and the problem that the flexible display screen is easy to damage in the folding process of the electronic equipment is solved.

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 not limited to the number of objects, e.g., 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 in the embodiments of the present application is described in detail below with reference to fig. 1 to 8 through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 4, the electronic apparatus according to the present invention includes a first apparatus body 100, a second apparatus body 200, a flexible display 300, a shaft assembly 400, and a link mechanism 500. The first device body 100 and the second device body 200 are basic structural members, and may provide a mounting base for each component in the electronic device. By way of example, the other element of the electronic device may be a battery, a circuit board, or the like. The components inside the electronic device are related to the type or use of the electronic device. For this reason, the embodiments of the present application are not limited to the kind and number of specific elements within the electronic device.
Referring to fig. 1 and 2, the first and second apparatus bodies 100 and 200 are rotatably coupled through the shaft assembly 400, so that the electronic apparatus can be folded or unfolded by the relative rotation of the first and second apparatus bodies 100 and 200.
In an alternative embodiment, the included angle between the first device body 100 and the second device body 200 ranges from a first angle to a second angle. In the case where the included angle between the first device body 100 and the second device body 200 is the first angle, the display surfaces of the flexible display screen 300 are located on the same plane, that is, the electronic device is in the unfolded state. In the case where the angle between the first device body 100 and the second device body 200 is the second angle, the first device body 100 and the second device body 200 are folded with each other, that is, the electronic device is in a folded state. Illustratively, the first and second apparatus bodies 100 and 200 may be rotated between 0 ° and 180 °.
In an alternative embodiment, the flexible display 300 of the electronic device is folded outwards, and the display surface of the flexible display 300 is located outside when the electronic device is folded. Illustratively, in the case where the included angle between the first device body 100 and the second device body 200 is the second angle, a side of the first device body 100 away from the flexible display screen 300 is stacked on a side of the second device body 200 away from the flexible display screen 300. That is, in the case where the electronic device is in the folded state, the first display screen 310 is located at a side of the first device body 100 facing away from the second device body 200, and the second display screen 320 is located at a side of the second device body 200 facing away from the first device body 100. The display surface of the flexible display screen 300 means: the flexible display 300 may display an image or text-side surface.
Referring to fig. 1 and 2, the flexible display 300 includes a first display 310, a second display 320. The first display screen 310 is connected to the second display screen 320, the first display screen 310 is slidably matched with the first device body, and the second display screen 320 is disposed on the second device body 200.
Referring to fig. 3 to 6, a first end of the link mechanism 500 is connected to the first display screen 310, a second end of the link mechanism 500 is connected to the shaft assembly 400, one of the second end of the link mechanism 500 and the shaft assembly 400 is provided with a pushing portion 511, the other is provided with a guide surface 410, the guide surface 410 is disposed obliquely with respect to an axis of the shaft assembly 400, and the pushing portion 511 is stopped against the guide surface 410.
During the folding process of the electronic device, the second end of the link mechanism 500 rotates relative to the shaft assembly 400, and the cooperation of the guide surface 410 and the pushing portion 511 causes the link mechanism 500 to move, so as to drive the first display screen 310 to move along the first device main body 100 in a direction approaching the shaft assembly 400.
In the unfolding process of the electronic device, the second end of the link mechanism 500 rotates relative to the shaft assembly 400, and the link mechanism 500 moves through the cooperation of the guide surface 410 and the pushing portion 511, so as to drive the first display screen 310 to move along the first device main body 100 in a direction away from the shaft assembly 400.
Referring to fig. 3 to 6, during the folding or unfolding process of the electronic device, the link mechanism 500 rotates with the first device body 100 relative to the shaft assembly 400, so as to drive the pushing portion 511 to slide along the guiding surface 410. Since the guide surface 410 is disposed obliquely with respect to the axis of the shaft assembly 400, the second section of the link mechanism 500 can move along the shaft assembly 400 and drive the first display screen 310 to move away from or close to the shaft assembly 400.
Note that, the movement of the first display screen 310 in the direction approaching the shaft assembly 400 means: the first display 310 approaches the shaft assembly 400 along its extending direction toward the shaft assembly 400. The first display screen 310 moving away from the shaft assembly 400 means: the first display 310 is remote from the shaft assembly 400 in a direction of extension that itself is away from the shaft assembly 400.
During folding of the electronic device, the first display screen 310 is moved in a direction approaching the shaft assembly 400 such that a side of the first display screen 310 approaching the shaft assembly 400 may form redundancy. Further, the side of the first display screen 310 near the shaft assembly 400 is gradually curved due to the force of the first and second device bodies 100 and 200. That is, the redundancy formed on the side of the first display screen 310 near the shaft assembly 400 can compensate for the radius difference between the flexible display screen 300 and the shaft assembly 400 during the folding process of the electronic device, so as to achieve the purpose of eliminating or reducing the extrusion force applied to the opposite part of the flexible display screen 300 and the shaft assembly 400.
In the process of unfolding the electronic equipment, the first display screen 310 moves towards the direction far away from the shaft assembly 400, so that a redundant part formed on one side of the first display screen 310 close to the shaft assembly 400 is stretched to adapt to the deformation of the shaft assembly 400 in the process of unfolding the electronic equipment, and the tensile force applied to the part of the flexible display screen 300 opposite to the shaft assembly 400 is eliminated or reduced, so that the purpose of protecting the flexible display screen 300 is achieved. In addition, the first display screen 310 moves in a direction away from the shaft assembly 400, so that wrinkles on the portion of the flexible display screen 300 opposite to the shaft assembly 400 after the electronic device is unfolded can be eliminated, and the display effect of the flexible display screen 300 can be improved.
In an alternative embodiment, the pushing portion 511 may be a bump disposed at the second end of the linkage 500. Of course, the pushing portion 511 may also be a push rod disposed at the second end of the linkage 500, where the push rod is fixedly disposed at the second end of the linkage 500, and one end of the push rod protrudes from the end surface of the second end of the linkage 500 near the guide surface 410, so that the second end of the linkage 500 may be stopped against the guide surface 410 by the push rod. Alternatively, an end of the pushing portion 511 abutting against the guide surface 410 is provided with a spherical convex surface, so that the pushing portion 511 slides along the guide surface 410.
In alternative embodiments, the guide surface 410 may be an inclined plane provided on the shaft assembly 400, or may be a concave or spiral surface provided on the shaft assembly 400. Illustratively, the guide surface 410 may be a groove wall of a groove provided to the shaft assembly 400 and surrounding a corresponding axis of the second end of the linkage 500. There are many ways to form the guide surface 410 described in the above embodiment, for example: can be realized by grooving, protruding blocks, mounting guide rails and the like. For this reason, the specific manner of forming the guide surface 410 is not limited in this application.
Referring to fig. 3 to 6, the link mechanism 500 includes a first slider 510 and a first link 520, the first slider 510 is connected to the first display screen 310 through the first link 520, the first slider 510 forms a second end of the link mechanism 500, and the first slider 510 is slidably engaged with the shaft assembly 400.
During the folding process of the electronic device, the first slider 510 moves along the shaft assembly 400 and drives the first display screen 310 to approach the shaft assembly 400. During the unfolding process of the electronic device, the first sliding member 510 moves along the shaft assembly 400 and drives the first display screen 310 away from the shaft assembly 400.
Referring to fig. 3 and 6, the shaft assembly 400 moves along the shaft assembly 400 by driving the first slider 510, thereby driving the first link 520 to rotate relative to the first apparatus body 100. Referring to fig. 3, during the rotation of the first link 520 relative to the first apparatus body 100, the angle between the first link 520 and the axial direction of the shaft assembly 400 increases or decreases, and thus the first apparatus body 100 may be pulled to move in a direction approaching or moving away from the shaft assembly 400.
It should be noted that, in the embodiment of the present application, the axial angle between the first link 520 and the shaft assembly 400 refers to: an included angle formed between the first link 520 and an axial direction corresponding to the rotation shaft of the shaft assembly 400 is less than or equal to 90 °.
In an alternative embodiment, the first link 520 is perpendicular to the shaft assembly 400 when the electronic device is unfolded, so that a dead point limit can be formed between the first link 520 and the shaft assembly 400, and the first display screen 310 can be prevented from sliding relative to the first device main body 100 when the electronic device is unfolded.
Illustratively, during folding of the electronic device, the first slider 510 may drive the first end of the first link 520 to move relative to the shaft assembly 400 such that the angle between the first link 520 and the shaft assembly 400 in the axial direction is reduced. As the axial included angle between the first link 520 and the shaft assembly 400 decreases, the first link 520 drives the first device body 100 to move in a direction approaching the shaft assembly 400, so that a portion of the flexible display screen 300 opposite to the shaft assembly 400 can form redundancy, so as to avoid the flexible display screen 300 being pulled in the folding process of the electronic device. During the unfolding process of the electronic device, the first slider 510 drives the first end of the first link 520 to move relative to the shaft assembly 400, so that the included angle between the first link 520 and the shaft assembly 400 increases. As the axial included angle between the first link 520 and the shaft assembly 400 increases, the first link 520 drives the first device body 100 to move away from the shaft assembly 400, so that redundancy formed in the portion of the flexible display screen 300 opposite to the shaft assembly 400 is eliminated, so as to avoid warping of the flexible display screen 300.
There are many ways in which the shaft assembly 400 may drive the first slider 510. For example: screw thread fit, gear rack transmission connection, cam mechanism connection, etc. To this end, embodiments of the present application are not limited to a particular manner of connection between the shaft assembly 400 and the first slider 510.
In a further alternative embodiment, first slider 510 is provided with a mounting hole through which shaft assembly 400 passes and is in rotational engagement with first slider 510. In the unfolding or folding process of the electronic device, the first device body 100 rotates relative to the shaft assembly 400 under the action of the first link 520, so that the pushing portion 511 can slide along the guiding surface 410, and further drives the first slider 510 to slide along the shaft assembly 400.
Illustratively, the first slider 510 may be provided with a mounting hole, and the shaft assembly 400 has a mounting shaft passing through the mounting hole and being in clearance fit with the mounting hole, such that the first slider 510 is not only rotatable relative to the shaft assembly 400, but also slidable along the shaft assembly 400. Alternatively, the first slider 510 is a sliding fit with a mounting shaft rotatably provided. During folding or unfolding of the electronic device, the first slider 510 slides along the axial direction of the mounting axial shaft assembly 400, and the first slider 510 rotates relative to the shaft assembly 400 by rotating the mounting shaft. The rotatable arrangement of the mounting shaft means that: the mounting shaft is rotatable relative to its mounting base. The mounting base of the mounting shaft can be a bracket or a mounting seat.
In another alternative embodiment, the first slider 510 may further be provided with a groove, and the shaft assembly 400 is at least partially disposed in the groove, so that the first slider 510 may not only rotate relative to the shaft assembly 400, but also slide along the shaft assembly 400. Illustratively, the first slider 510 may be provided with an arcuate recess and the shaft assembly 400 may be provided with a mounting shaft that slidably mates with the arcuate recess.
Referring to fig. 4 to 6, a first end of the first link 520 is rotatably coupled to the first display screen 310, a second end of the first link 520 is rotatably coupled to the first slider 510, and the first link 520 is rotated about a first axis, which is perpendicular to the shaft assembly 400, with respect to the first slider 510. The first axis perpendicular to the shaft assembly 400 means: the first axis is perpendicular to a corresponding axis of the shaft assembly 400. Illustratively, the axis of the shaft assembly 400 may correspond to the axis of rotation of the first apparatus body 100 with respect to the shaft assembly 400.
Illustratively, during the movement of the first slider 510 along the shaft assembly 400, the first slider 510 drives the second end of the first link 520 to move along the axial direction of the shaft assembly 400, such that the first link 520 rotates around the connection between the first link 520 and the flexible display screen 300. In the process of rotating the first link 520 relative to the flexible display screen 300, the included angle between the first link 520 and the axial direction of the shaft assembly 400 increases or decreases, so as to drive the first section of the flexible display screen 300 to move towards or away from the shaft assembly 400.
Illustratively, during the folding process of the electronic device, the first slider 510 drives the first link 520 to rotate relative to the first display screen 310. In the process that the first link 520 rotates relative to the first display screen 310, the axial included angle between the first link 520 and the shaft assembly 400 is reduced, so as to drive the first display screen 310 to move towards the direction close to the shaft assembly 400, so as to avoid the tension at the joint of the first display screen 310 and the second display screen 320.
Referring to fig. 3 to 7, the link mechanism 500 further includes a slider 530 and a guide rail 540, the slider 530 is disposed at a side of the flexible display screen 300 remote from the display surface, and the slider 530 is rotatably connected to the first end of the first link 520. The guide rail 540 is provided to the first apparatus body 100, and the slider 530 is slidably engaged with the guide rail 540. During folding of the electronic device, the first link 520 pulls the slider 530 to slide along the guide rail 540. Referring to fig. 7, the guide rail 540 may be a sliding groove, and the slider 530 is at least partially embedded in the sliding groove, so that the slider 530 may slide along the sliding groove.
The guide rail 540 may provide a guide for the sliding of the slider 530 with respect to the first apparatus body 100. Also, the first device body 100 may further provide support for the connection of the first link 520 and the flexible display screen 300 by a sliding fit between the guide rail 540 and the slider 530. The guide rail 540 may be used to act on the slider 530 and rotate the first link 520 and the first slider 510 relative to the shaft assembly 400 during folding or unfolding of the electronic device. This embodiment can reduce the stress at the connection between the flexible display 300 and the first link 520, thereby protecting the flexible display 300.
There are many ways in which the slider 530 can be slidably engaged with the rail 540. Illustratively, the rail 540 may be a "T" shaped slot with the slider 530 at least partially positioned therein. The guide rail 540 may also be a guide rod, and the slider 530 is provided with a through hole, so that the slider 530 is in sliding fit with the guide rod. Therefore, the present embodiment does not limit the specific structure of the sliding engagement of the slider 530 with the guide rail 540.
In an alternative embodiment, referring to fig. 3, the number of the first sliding members 510 may be two, and the two first sliding members 510 may be symmetrically distributed at two ends of the shaft assembly 400, so as to equalize stress of the flexible display screen 300, thereby preventing the flexible display screen 300 from being jammed when sliding along the first device body 100 and/or the second device body 200. Of course, the number of the first sliding members 510 may be plural, and the plurality of first sliding members 510 may be uniformly distributed in the shaft assembly 400 along the axial direction of the shaft assembly 400. For this reason, the present application does not limit the specific number of the first sliders 510.
Referring to fig. 4 and 5, the electronic device further includes an elastic member 600, the elastic member 600 is connected to the shaft assembly 400 and the first slider 510, respectively, and the elastic member 600 drives the first slider 510 to make the pushing portion 511 abut against the guide surface 410. That is, the elastic force generated by the elastic member 600 acts on the shaft assembly 400 and the first slider 510, respectively, so that the pushing portion 511 can keep a state of being stopped against the guide surface 410 during the folding or unfolding process of the electronic device, and further, the first slider 510 can be reset during the repeated folding or unfolding process of the electronic device.
During use of the electronic device, the flexible display 300 may be subjected to forces in various directions, such as: the friction force generated by the fingers during the sliding of the surface of the flexible display 300. By arranging the elastic member 600, the first sliding member 510 can be prevented from moving in a direction away from the guiding surface 410, and the position of the first sliding member 510 can be defined by using the elastic member 600 and the guiding surface 410, so that the sliding of the flexible display screen 300 relative to the first device main body 100 during the operation of the flexible display screen 300 by a user can be prevented. Therefore, the electronic device described in the above embodiment does not need to add a damping structure for preventing the flexible display screen 300 from sliding relative to the first device body 100.
Referring to fig. 3, 4 and 8, the shaft assembly 400 is provided with a limiting groove 420, and the limiting groove 420 is caught in the guide surface 410. The pushing portion 511 is at least partially embedded in the limit groove 420 when the electronic device is unfolded and/or folded. The limiting groove 420 is in limiting fit with the pushing part 511, so that the rotation of the first device main body 100 relative to the shaft assembly 400 can be limited, the sliding resistance of the flexible display screen 300 relative to the first device main body 100 can be increased, and further the sliding of the flexible display screen 300 relative to the first device main body 100 under the condition that the first device main body 100 and the second device main body 200 of the electronic device do not rotate relatively can be avoided.
The number of the limiting grooves 420 is plural, and the limiting grooves 420 are arranged at intervals along the track of the pushing portion 511 moving relative to the guiding surface 410. Referring to fig. 3, during the rotation of the first apparatus body 100 relative to the shaft assembly 400, the track of the pushing portion 511 relative to the guide surface 410 is an axis around which the first apparatus body 100 rotates relative to the shaft assembly 400. In the above embodiment, by providing the plurality of limiting grooves 420, not only the resistance applied during the rotation of the first apparatus body 100 relative to the shaft assembly 400 can be increased, but also the first apparatus body 100 and the second apparatus body 200 can be kept at different included angles by different limiting grooves 420. For example, the limiting groove 420 and the pushing portion 511 may be in a limiting fit, so that an included angle between the first device body 100 and the second device body 200 is an acute angle. In the case where the angle between the first apparatus body 100 and the second apparatus body 200 is an acute angle, one of the first apparatus body 100 and the second apparatus body 200 may be used as a support base, and the other may support a part of the flexible display screen 300. For example, in the case of performing screen display using an electronic device, one of the first device body 100 and the second device body 200 may be used as a support, and the flexible display screen 300 positioned on the other may be used to display a screen, thereby enabling a portion of the flexible display screen 300 where the screen is displayed to be disposed obliquely, so that a user can view the screen displayed in the flexible display screen 300.
