Description
Technical Field
The invention relates to the technical field of communication equipment, in particular to a mobile terminal.
Background
With the development of the mobile terminal industry, people expect that the screen size of the mobile terminal is as large as possible, for example, the screen size of a smart phone is developed from the first 3.5 inches to the current 6 inches or even 7 inches. Even with the current screen, the use requirements of people for watching screens, reading books and the like cannot be met; on the other hand, the larger the screen, the larger the size of the mobile terminal, and the more inconvenient it is to carry, thus creating a contradiction between the larger screen demand and the portability.
In order to solve the above-mentioned contradiction, a foldable flexible display screen is produced, and a mobile terminal using the flexible display screen can be folded correspondingly. The mobile terminal has wide application prospect because the mobile terminal can meet both the requirement of large screen and the portability. Referring to fig. 1 to 4, a conventional mobile terminal includes a first housing 110, a second housing 120, a hinge 130, and a flexible display 140, wherein the first housing 110 and the second housing 120 are hinged by the hinge 130, the flexible display 140 is disposed on the first housing 110 and the second housing 120, and the hinge 130 is located below the flexible display 140. The folding and unfolding of the mobile terminal can be achieved by the relative rotation of the first housing 110 and the second housing 120.
With the above structure, the rotation axis of the entire mobile terminal, the central axis of the rotation axis 130, and the rotation axis of the flexible display 140 are the same axis. In the unfolded state (i.e., the state shown in fig. 1 and 2), the length of the flexible display screen 140 is L1+ L2, where L1 and L2 are the lengths from the two opposite edges of the flexible display screen 140 to the central axis of the rotation shaft 130, respectively; in the folded state (i.e., the state shown in fig. 3 and 4), the length of the flexible display screen 140 is L1+ L2+ rr, where R is the radius of the rotation shaft 130. Obviously, the flexible display 140 is longer by π R in the folded state than in the unfolded state, and the flexible display 140 is easily damaged and has a short lifetime because the flexible display 140 is not elastic in the length direction.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 5 to 8, the mobile terminal according to the embodiment of the present invention includes a first housing 200, a second housing 300, a flexible display 400, a first hinge mechanism 500a, and a second hinge mechanism 500 b. The first chassis 200 and the second chassis 300 are hinged by the first hinge mechanism 500a and the second hinge mechanism 500b so that they can be rotated about the hinge axis Z1, thereby forming an unfolded state and a folded state of the mobile terminal. The flexible display 400 is disposed on the first chassis 200 and the second chassis 300, that is, the first chassis 200 and the second chassis 300 support the flexible display 400 together. The flexible display 400 has a bending region 410 and planar portions 420 distributed on both sides of the bending region 410, and the bending region 410 is located between the first hinge mechanism 500a and the second hinge mechanism 500 b. Here, the bending region 410 refers to a portion where bending deformation occurs when the flexible display 400 is folded.
In the unfolded state, the first chassis 200 and the second chassis 300 are distributed side by side, and the whole flexible display 400 is in a flat state, thereby obtaining a larger display area. At this time, as viewed in the thickness direction of the flexible display 400, the bending region 410 thereof is located between the first hinge mechanism 500a and the second hinge mechanism 500 b. When the mobile terminal needs to be folded, the first housing 200 and the second housing 300 are driven to rotate relatively, and then the flexible display 400 is driven to bend based on the rotation of the bending region 410, and finally reaches a folded state. In the folded state, the bending region 410 bends, and the bending region 410 is still located between the first hinge mechanism 500a and the second hinge mechanism 500b as viewed in the thickness direction of the flexible display 400. At this time, bending axis Z2 of bending region 410 is offset from hinge axis Z1 of first chassis 200 and second chassis 300 (i.e., hinge axis Z1 is not collinear with bending axis Z2), and bending axis Z2 is closer to planar portion 420 than hinge axis Z1. It should be noted that the bending axis Z2 and the hinge axis Z1 may be parallel to each other. In a specific structure, the first hinge mechanism 500a and the second hinge mechanism 500b are disposed outside the area covered by the flexible display 400, that is, the first hinge mechanism 500a and the second hinge mechanism 500b are not disposed below the flexible display 400.
After the above arrangement mode is adopted, in the process of folding the mobile terminal, the bending area 410 of the flexible display screen 400 does not need to rotate around the hinge axis Z1, and the bending axis Z2 is closer to the plane portion 420 of the flexible display screen 400, so that the change of the length of the flexible display screen 400 is small, even the change is not generated, the flexible display screen is not easy to be pulled, and the service life of the flexible display screen is longer.
In order to make the rotation between the first and second housings 200 and 300 smoother while simplifying the structure of the mobile terminal, the first and second hinge mechanisms 500a and 500b may be provided in a symmetrical structure, which is a plane passing through the midpoint of the bending axis Z2 and perpendicular to the bending axis Z2. With this structure, the rotation axes of the first hinge mechanism 500a and the second hinge mechanism 500b are collinear, and thus the rotation between the first housing 200 and the second housing 300 can be smoother.
Referring to fig. 6, when the mobile terminal is in the unfolded state, the length of the flexible display 400 is L1+ L2+2 × L3+ 2R; referring to fig. 8, when the mobile terminal is in a folded state, the flexible display 400 has a length of L1+ L2+ tr. In order to make the length of the flexible display screen 400 in the unfolded state equal to the length of the flexible display screen 400 in the folded state, L3 ≈ ((pi-2)/2) R ≈ 0.57R may be calculated. L1 is a distance between an edge of one side of the bending region 410 and an edge of the planar portion 420 on one side of the flexible display screen 400, L2 is a distance between an edge of the other side of the bending region 410 and an edge of the planar portion 420 on the other side of the flexible display screen 400, L3 is a distance between the bending axis Z2 and the hinge axis Z1 in the folded state, and R is a rotation radius of the first hinge mechanism 500 a.
Further, in consideration of the thickness of the first chassis 200 and the second chassis 300, the assembly error between the two, and the like, the embodiment of the invention sets L3 to be 0.5 to 0.7R, so that the flexible display 400 does not substantially change in length during the process of folding the mobile terminal.
As shown in fig. 9 to 15, at least one of the first hinge mechanism 500a and the second hinge mechanism 500b includes a first rotating member 510 connected to the first housing 200, a second rotating member 520 connected to the second housing 300, and a rotating shaft 530, wherein the first rotating member 510 includes a first sleeve 511, the second rotating member 520 includes a second sleeve 521, and the rotating shaft 530 penetrates the first sleeve 511 and the second sleeve 521 to form a shaft hole matching with the first sleeve 511 and the second sleeve 521. When the mobile terminal is folded, a driving force may be applied to the first housing 200 or the second housing 300, and the first sleeve 511 and the second sleeve 521 rotate about the rotation shaft 530, so that the first housing 200 and the second housing 300 rotate relatively. The hinge mechanism has a simple structure, and meanwhile, the stability in the rotating process is high.
In the above structure, the first housing 200 and the second housing 300 may be directly fixed on the first sleeve 511 and the second sleeve 521, respectively, but in this way, the connection area between the first housing 200 and the first sleeve 511, and between the second housing 300 and the second sleeve 521 is small, which results in poor structural strength of the mobile terminal. For this purpose, the first rotating member 510 may further include a first connecting plate 512 connected to the first sleeve 511, the first connecting plate 512 may be provided with a plurality of first connecting holes 512a, and the first connecting plate 512 is fixedly connected to the first housing 200 through the first connecting holes 512 a. At this time, the first connection plate 512 and the first housing 200 are in surface contact, so that the connection strength between the two is higher.
Similarly, the second rotating member 520 may further include a second connecting plate 522 connected to the second sleeve 521, the second connecting plate 522 may have a plurality of second connecting holes 522a, and the second connecting plate 522 is fixedly connected to the second housing 300 through the second connecting holes 522 a.
Generally, the flexible display 400 can be folded in one direction only, and once a user folds the flexible display 400 in the wrong direction, the service life of the flexible display 400 will be adversely affected, so that in order to prevent the wrong folding direction, a corresponding structure may be provided to limit the folding direction of the flexible display 400. Specifically, one of the first sleeve 511 and the second sleeve 521 is provided with a stop protrusion 541, the other is provided with a stop groove 542, the stop protrusion 541 extends into the stop groove 542, and the two are in limit fit in the relative rotation direction of the first sleeve 511 and the second sleeve 521. That is, when the first sleeve 511 and the second sleeve 521 rotate relatively, the stopping protrusions 541 slide in the stopping grooves 542, and when the stopping protrusions 541 slide to the side walls of the stopping grooves 542, the side walls block the stopping protrusions 541 from sliding continuously, so that the first sleeve 511 and the second sleeve 521 cannot rotate relatively, thereby achieving the aforementioned purpose.
The stopper groove 542 has a first stopper groove wall 542a and a second stopper groove wall 542b, and in the folded state, the stopper projection 541 is in limit-fit with the first stopper groove wall 542a, and in the unfolded state, the stopper projection 541 is in limit-fit with the second stopper groove wall 542 b. Thus, the distance between the first stop groove wall 542a and the second stop groove wall 542b in the relative rotation direction of the first sleeve 511 and the second sleeve 521 is the maximum value of the relative rotation stroke of the first housing 200 and the second housing 300, so that the structure is more convenient for designing the structure of the mobile terminal. In a more specific structure, the first and second stop groove walls 542a and 542b may be oppositely disposed along a radial direction of the first sleeve 511 or the second sleeve 521 such that a relative rotation angle of the first sleeve 511 and the second sleeve 521 is substantially 180 °.
In order to improve rotational stability, at least one of the first sleeve 511 and the second sleeve 521 may be provided in plurality, and the first sleeve 511 and the second sleeve 521 are alternately arranged. In a specific embodiment, the second sleeves 521 are distributed on both end sides of the first sleeve 511, the stopping protrusions 541 are disposed on both ends of the first sleeve 511, the stopping grooves 542 are disposed on both ends of the second sleeve 521, or the stopping grooves 542 are disposed on both ends of the first sleeve 511, and the stopping protrusions 541 are disposed on both ends of the second sleeve 521. At this time, the two ends of the first sleeve 511 form a stopping structure with the second sleeves 521 at the two sides, so that the stopping effect is better, the mobile terminal is not easy to deflect due to uneven stress in the folding process, and the folding stability is higher.
The mobile terminal disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader or a wearable device. Of course, the mobile terminal may also be other terminal devices, which is not limited in this embodiment of the present invention.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
