The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 10, an embodiment of the present application discloses an electronic device including a first housing 110, a second housing 120, a flexible display 200, and an actuator 300.
The first housing 110 and the second housing 120 are basic components of the electronic device, and can provide a foundation for the flexible display 200 and the transmission mechanism 300.
A first end of the flexible display 200 is slidably fitted with the first housing 110, a second end of the flexible display 200 is connected with the second housing 120, and the flexible display 200 includes a first portion 210.
The transmission mechanism 300 includes a rotating disc 310, the rotating disc 310 is rotatably disposed in the first housing 110, that is, the rotating disc 310 rotates around its axis, the rotating disc 310 has a first connecting surface 311 and a second connecting surface 312 which are opposite to each other, the first connecting surface 311 is connected to the first end of the flexible display screen 200, the second connecting surface 312 is connected to the second housing 120, the rotating disc 310 drives the second housing 120 to slide relative to the first housing 110 so as to switch the flexible display screen 200 between the extended state and the retracted state, when the flexible display screen 200 is in the extended state, the first portion 210 is located on one side of the second connecting surface 312 of the rotating disc 310, at this time, the display area of the flexible display screen 200 is large, and a good visual impact can be provided for a user, so that the user can play games, watch movies, and other activities; when the flexible display panel 200 is in the contracted state, the first portion 210 is located at the side of the first connection surface 311 of the rotating disc 310, and the electronic device is small in overall size and convenient to carry.
In this embodiment, in the process that the rotating disc 310 rotates around its axis, the rotating disc 310 pushes the second housing 120 to slide relative to the first housing 110, at this moment, the second housing 120 drives the second end of the flexible display screen 200 to move, and the second connecting surface 312 of the rotating disc 310 is connected with the first end of the flexible display screen 200, at this moment, the rotating disc 310 will push the first end of the flexible display screen 200 to move, so that the two ends of the flexible display screen 200 move synchronously along with the rotating disc 310, thereby avoiding only one end of the flexible display screen 200 from dragging the other end thereof to move in the transmission process of the lead screw nut, so as to improve the telescopic stability of the flexible display screen 200, and further prolong the service life of the flexible display screen 200. Therefore, the embodiment of the application can solve the problem that the flexible display screen 200 is poor in expansion stability.
Optionally, the rotating disc 310 may have a double-cam structure, and the two cams disposed opposite to each other are respectively connected to the second housing 120 and the first end of the flexible display screen 200, at this time, structures matched with the cams need to be respectively disposed on the inner surfaces of the second housing 120 and the flexible display screen 200, which is difficult to design; also, the rotating disk 310 of the double cam structure has a large weight and volume. Therefore, in an alternative embodiment, the transmission mechanism 300 further includes a first connecting rod 320 and a second connecting rod 330, a first end of the first connecting rod 320 is movably connected to the first connecting surface 311, that is, the first connecting rod 320 is driven to move during the rotation of the rotating disc 310, a second end of the first connecting rod 320 is hinged to the first end of the flexible display panel 200, a first end of the second connecting rod 330 is movably connected to the second connecting surface 312, that is, the second connecting rod 330 is driven to move during the rotation of the rotating disc 310, a second end of the second connecting rod 330 is hinged to the second housing 120, the rotating disc 310 drives the flexible display panel 200 to move through the first connecting rod 320 and the second connecting rod 330, and the second connecting rod 330 drives the second end of the flexible display panel 200 to move through the second housing 120 during the movement of the second connecting rod 330; in the process of moving the first link 320, the first link 320 pushes the first end of the flexible display screen 200 to move, and the displacement amounts of the first link 320 and the second link 330 are the same, so that the two ends of the flexible display screen 200 move synchronously. When the flexible display screen 200 is in the unfolded state, the distance between the first end of the first link 320 and the first end of the second link 330 is a first distance; with the flexible display 200 in the collapsed state, a distance between the first end of the first link 320 and the first end of the second link 330 is a second distance, wherein the first distance is greater than the second distance. When the flexible display screen 200 is switched from the expanded state to the contracted state, the first end of the first link 320 and the first end of the second link 330 are close to each other, so that the distance between the two ends of the first casing 110 and the second casing 120 which are away from each other is reduced, and at this time, the electronic device has a small volume and is convenient to carry; when the flexible display screen 200 is switched from the retracted state to the extended state, the first end of the first link 320 and the first end of the second link 330 are away from each other, so that the distance between the two ends of the first casing 110 and the second casing 120, which are away from each other, is increased, and at this time, the display area of the flexible display screen 200 is increased. Therefore, the transmission mechanism 300 with such a structure according to the embodiment of the present application is not only convenient to connect with the second housing 120 and the flexible display panel 200, so as to reduce the design difficulty, but also the weight and the volume of the transmission mechanism 300 are small.
In a further alternative embodiment, the first connection surface 311 is provided with a first guide slot 311a, the first end of the first link 320 is movably engaged with the first guide slot 311a, the second connection surface 312 is provided with a second guide slot 312a, and the first end of the second link 330 is movably engaged with the second guide slot 312 a. During the rotation of the rotary disk 310, the first link 320 and the second link 330 move along the first guide groove 311a and the second guide groove 312a, respectively, and the first guide groove 311a and the second guide groove 312a provide guidance for the first link 320 and the second link 330, respectively, so that the first link 320 and the second link 330 are more stable during approaching or departing from each other. Of course, the first connection surface 311 and the second connection surface 312 may also be respectively provided with a first guide protrusion and a second guide protrusion, the first end of the first link 320 is movably engaged with the first guide protrusion, and the first end of the second link 330 is movably engaged with the second guide protrusion, which not only increases the thickness of the rotary disk 310, but also easily damages the first guide protrusion and the second guide protrusion during the process of the first link 320 and the second link 330 approaching to or departing from each other, so that the effect of providing the guide protrusions on the first connection surface 311 and the second connection surface 312 of the rotary disk 310 is not as good as the effect of providing the guide grooves.
The end of the first link 320 and the end of the first end of the second link 330 may be respectively provided with a first bending portion and a second bending portion, which are movably matched with the first guide slot 311a and the second guide slot 312a, so that jamming and large abrasion are easily caused in the process of mutual approaching or mutual leaving of the first link 320 and the second link 330. Based on this, in a further alternative embodiment, the transmission mechanism 300 further includes a first rolling member 340 and a second rolling member 350, the first rolling member 340 is disposed in the first guide groove 311a, the first end of the first link 320 is movably engaged with the first guide groove 311a through the first rolling member 340, the second rolling member 350 is disposed in the second guide groove 312a, and the first end of the second link 330 is movably engaged with the second guide groove 312a through the second rolling member 350. In the process that the first connecting rod 320 and the second connecting rod 330 are close to or far away from each other, the transmission mechanism 300 with the structure can prevent the jamming phenomenon, so that the movement flexibility of the first connecting rod 320 and the second connecting rod 330 is improved, the abrasion is less, and the service life of the transmission mechanism 300 can be prolonged.
The first guide slot 311a and the second guide slot 312a may be linear slots, and at this time, in the rotation process of the rotating disc 310, the first connecting rod 320 and the second connecting rod 330 will rotate while moving relatively, which easily causes the first connecting rod 320 and the second connecting rod 330 to be jammed. In an alternative embodiment, the first guide slot 311a and the second guide slot 312a are both arc-shaped slots, and at this time, the first link 320 and the second link 330 only move relatively, which is beneficial to improving the moving smoothness of the first link 320 and the second link 330, thereby improving the user experience.
Optionally, in the extending direction of the central axis of the rotating disc 310, when the orthographic projection of the second guiding groove 312a overlaps the orthographic projection of the first guiding groove 311a, at this time, two opposite sides of the same structure of the rotating disc 310 are both provided with guiding grooves, which will result in that the structural strength of the position of the rotating disc 310 is greatly reduced, and the acting forces of the first connecting rod 320 and the second connecting rod 330 acting on the rotating disc 310 respectively are concentrated. Based on this, in another alternative embodiment, the orthographic projection of the second guide slot 312a is located outside the orthographic projection of the first guide slot 311a, in this case, the first guide slot 311a and the second guide slot 312a may be opened at different structures of the rotating disc 310, which not only can ensure the structural strength of the rotating disc 310, but also the acting forces of the first link 320 and the second link 330 on the rotating disc 310 are relatively dispersed, which is beneficial to protecting the rotating disc 310.
When the first end and the second end of the first guide slot 311a and the first end and the second end of the second guide slot 312a are both located between the central region and the edge region of the rotary disk 310, in order to ensure that the flexible display panel 200 has a sufficiently large display area in the unfolded state, the size of the rotary disk 310 needs to be increased, which increases the volume and weight of the rotary disk 310, or increases the length of the first link 320 and the second link 330, which easily causes the first link 320 and the second link 330 to bend and deform when the applied force is large. In view of this, in yet another alternative embodiment, both the first end of the first guide slot 311a and the first end of the second guide slot 312a extend to the central region of the rotary disk 310, and both the second end of the first guide slot 311a and the second end of the second guide slot 312a extend to the edge region of the rotary disk 310. In this case, on the basis of ensuring that the flexible display 200 has a sufficiently large display area in the unfolded state, the size of the rotary disk 310 can be set small, and the utilization rate of the rotary disk 310 can be improved.
In yet another alternative embodiment, the second end of the first guide slot 311a and the second end of the second guide slot 312a are respectively located at two sides of the central axis of the rotating disc 310, when the protruding direction of the first guide slot 311a is the same as the protruding direction of the second guide slot 312a, the first guide slot 311a and the second guide slot 312a are both located on the half structure of the rotating disc 310, during the rotation of the rotating disc 310, one of the first connecting rod 320 and the second connecting rod 330 may only move, while the other one needs to rotate while moving, and in order to ensure that the displacement amount of the two ends of the flexible display screen 200 is equal, the length of the connecting rod needs to be set longer; meanwhile, since the first link 320 and the second link 330 have different movement patterns, the difficulty of disposing the transmission mechanism 300 may be increased. Therefore, optionally, the protruding direction of the first guide slot 311a is opposite to the protruding direction of the second guide slot 312a, and at this time, the first guide slot 311a and the second guide slot 312a are respectively located at two opposite portions of the rotating disc 310, and in the process of rotating the rotating disc 310, the first connecting rod 320 and the second connecting rod 330 may only move, and at this time, the lengths of the first connecting rod 320 and the second connecting rod 330 may be set to be equal, and at this time, the movement forms of the two are the same, which is beneficial to reducing the difficulty in setting the transmission mechanism 300. Meanwhile, the first guide groove 311a and the second guide groove 312a are distributed relatively uniformly on the rotating disc 310, and the rotating disc 310 is not easily shaken due to unstable center of gravity.
In an alternative embodiment, the first housing 110 is provided with a plurality of sliding slots 111 arranged at intervals along a first direction, the second housing 120 is provided with a plurality of sliding rails 121 arranged at intervals along the first direction, and the plurality of sliding rails 121 and the plurality of sliding slots 111 are matched in a one-to-one correspondence manner, so that the second housing 120 is slidably connected with the first housing 110, wherein the first direction is perpendicular to the sliding direction of the second housing 120. This scheme adopts spout 111 and slide rail 121 sliding fit's mode, and area of contact between the two is great, is favorable to improving the motion stability of flexible display screen 200 in the switching process between expansion state and shrink state. Optionally, at least one of the sliding rails 121 is a second connecting rod 330, that is, in the process of rotating the rotating disc 310, the rotating disc 310 drives a part of the sliding rails 121 to move, and meanwhile, the part of the sliding rails 121 is in sliding fit with the corresponding sliding grooves 111, that is, the second connecting rod 330 has a dual-purpose effect; in addition, when at least one of the plurality of sliding rails 121 is the second link 330, the number of parts of the electronic device can be reduced.
Optionally, the second link 330 and the second housing 120 may be a split structure, so as to facilitate the disassembly and maintenance of the second link 330; of course, the second connecting rod 330 and the second housing 120 may also be an integrated structure, which facilitates the assembly and disassembly of the electronic device and improves the structural strength thereof.

This scheme is favorable to improving the space utilization who holds the chamber, and each structure of electronic equipment inside is compacter simultaneously, and flexible display 200's stability is better. Of course, the rotating disc 310 may be disposed outside the bracket 113, but this will increase the thickness of the electronic device, so this solution is not as good as disposing the rotating disc 310 in the accommodating cavity of the bracket 113.
Optionally, the electronic device further includes a rotating shaft 800, the rotating shaft 800 is rotatably disposed on the outer shell 112, the rotating shaft 800 is located between the outer shell 112 and the support 113, the rotating shaft 800 is located on a side of the support 113 away from the second casing 120, and a central axis of the rotating shaft 800 extends along a length direction of the electronic device, that is, an extending direction of the rotating shaft 800 is perpendicular to a moving direction of the second casing 120. The inner surface of the flexible display screen 200 contacts with the circumferential surface of the rotation shaft 800, and the rotation shaft 800 is used for supporting the flexible display screen 200 and is beneficial to improving the smoothness of the movement of the flexible display screen 200.
In an alternative embodiment, the electronic device further includes a driving source 400, the driving source 400 is disposed in the first housing 110, and the driving source 400 may be connected to an edge of the rotating disk 310, where the driving force output from the driving source 400 easily causes the rotating disk 310 to tilt. Based on this, optionally, the rotating disc 310 is provided with a center hole 313, the electronic device further includes a connecting shaft 500, an output shaft of the driving source 400 is connected to a first end of the connecting shaft 500, a second end of the connecting shaft 500 passes through the center hole 313 to be rotatably connected to the first housing 110, the driving source 400 drives the rotating disc 310 to rotate through the connecting shaft 500, and at this time, the driving force output by the driving source 400 acts on the center area of the rotating disc 310, so that the rotating disc 310 can be prevented from deflecting, and the flatness of the flexible display screen 200 can be ensured. In the embodiment in which the first housing 110 includes the outer case 112 and the bracket 113, the driving source 400 is disposed at the outer case 112, and the second end of the connecting shaft 500 is inserted into the receiving cavity of the bracket 113 and rotatably connected with the bracket 113 to facilitate the disposition of the driving source 400.
