Technical Field
The present application relates to the field of mobile terminal technology, and more particularly, to a foldable mobile terminal.
Background
The existing folding mobile terminal provides various folding mechanisms to meet the length difference change generated when the two sides of the mobile terminal are switched between the unfolded state and the folded state, and the folding mechanisms occupy larger space and are not beneficial to the size miniaturization of the mobile terminal.
Disclosure of Invention
One technical problem solved by the present application is how to make a folder type mobile terminal smaller in size.
A folder-type mobile terminal comprising:
a housing assembly including a first housing and a second housing;
a display screen disposed in combination with the first housing and the second housing;
folding mechanism, including loading board, first apron, second apron, first rocking arm and second rocking arm, the loading board have with first apron rotates the first side of connecting, and with the second apron rotates the second side of connecting, first apron with first casing sliding connection, the second apron with second casing sliding connection, the both ends of first rocking arm rotate respectively connect in the second side of loading board with first casing, the both ends of second rocking arm rotate respectively connect in the first side of loading board with the second casing.
In the foldable mobile terminal, the first cover plate can rotate relative to the bearing plate, the first shell can slide and stretch relative to the first cover plate, the second cover plate can rotate relative to the bearing plate, and the second shell can slide and stretch relative to the second cover plate, so that the length of the shell assembly can be increased or reduced in the unfolding and folding processes, the requirement for the length difference change between the display screen and the shell assembly is met, and the foldable mobile terminal can be smoothly unfolded and folded. Because the two ends of the first rotating arm are respectively and rotatably connected to the second side and the first shell of the bearing plate, the two ends of the second rotating arm are respectively and rotatably connected to the first side and the second shell of the bearing plate, and the projections of the first rotating arm and the second rotating arm in the folded state can be in a cross shape, the arrangement enables the accommodating space formed by the first rotating arm and the second rotating arm in the folded state for accommodating the folded part of the display screen to be smaller, thereby being beneficial to the compact arrangement of parts of the folding mobile terminal and the reduction of the thickness of the folding mobile terminal in the folded state. The first rotating arm and the second rotating arm can reduce the tensile stress of the shell assembly on the display screen in the rotating process of the folding mobile terminal so as to prevent the display screen from being pulled and deformed in the rotating process, and therefore the service life of the display screen can be prolonged.
A folder-type mobile terminal comprising:
a flexible screen;
the shell assembly comprises a first shell and a second shell, and the first shell and the second shell are respectively connected with the flexible screen; and
the folding mechanism comprises a bearing plate, a first cover plate, a second cover plate, a first rotating arm and a second rotating arm, wherein the first cover plate and the second cover plate are respectively in rotating connection with the bearing plate; two ends of the first rotating arm are respectively and rotatably connected to the bearing plate and the first shell, and two ends of the second rotating arm are respectively and rotatably connected to the bearing plate and the second shell;
when the folding mobile terminal is switched between the unfolding state and the folding state, the first shell can drive the first cover plate to rotate relative to the bearing plate, and meanwhile, the first shell slides and stretches relative to the first cover plate; the second shell can drive the second cover plate to rotate relative to the bearing plate, and meanwhile, the second shell stretches and retracts in a sliding mode relative to the second cover plate; when in the closed state, orthographic projections of the first rotating arm and the second rotating arm on a reference plane are intersected, and the reference plane is a geometric plane perpendicular to the rotating axis of the first cover plate.
In the folding mobile terminal, the first shell can drive the first cover plate to rotate relative to the bearing plate, and the first shell can slide and stretch relative to the first cover plate, the second shell can drive the second cover plate to rotate relative to the bearing plate, and the second shell can slide and stretch relative to the second cover plate, so that the length of one side of the shell assembly, which is back to the flexible screen, can be increased or reduced in the unfolding and folding processes, the requirement on the length difference change between the flexible screen and the shell assembly is met, and the folding mobile terminal can be smoothly unfolded and folded. Since orthographic projections of the first rotating arm and the second rotating arm on the reference plane intersect in the closed state, the arrangement is such that a receiving space formed by the first rotating arm and the second rotating arm in the closed state for receiving a folded portion of the flexible screen is small, thereby facilitating compact arrangement of parts of the folding mobile terminal and facilitating reduction of thickness of the folding mobile terminal in the closed state. The first rotating arm and the second rotating arm can reduce the tensile stress of the shell assembly on the flexible screen in the rotating process of the folding mobile terminal so as to prevent the flexible screen from being pulled and deformed in the rotating process, and therefore the service life of the flexible screen can be prolonged.

Referring to fig. 1 and 2, in one embodiment, the folding mobile terminal 10 is a smart phone. The folder-type mobile terminal 10 includes a display screen 100, a housing assembly 200, and a folding mechanism 300. Referring to fig. 3 and 4 together, the case assembly 200 includes a first case 210 and a second case 220, and the first case 210 and the second case 220 are respectively connected to the display screen 100. The display screen 100 can be used to display information and provide an interactive interface for a user, and the display screen 100 can be fixedly connected to the first casing 210 and the second casing 220 by means of glue dispensing and the like. The first housing 210 and the second housing 220 may form mounting spaces for mounting electronic components such as a circuit board, a battery, a receiver, a speaker, a camera, etc. of the folder type mobile terminal 10, respectively. The circuit board may integrate electronic components such as a main controller, a storage unit, an antenna module, and a power management module of the foldable mobile terminal 10, and the battery may supply power to the electronic components such as the display screen 100, the circuit board, the receiver, the speaker, and the camera. In other embodiments, the foldable mobile terminal 10 may be a tablet computer or the like.
Referring to fig. 3 and 4 together, the case assembly 200 enables the folder-type mobile terminal 10 to be switched between the unfolded state and the folded state by the folder mechanism 300. The folding mechanism 300 includes a bearing plate 310, a first cover plate 320, a second cover plate 330, a first rotating arm 340 and a second rotating arm 350, the first cover plate 320 and the second cover plate 330 are bar-shaped, and the first cover plate 320 and the second cover plate 330 are respectively connected with the bearing plate 310 in a rotating manner. Referring to fig. 5 and 6 together, the first and second rotating arms 340 and 350 have a substantially L-shape. Referring to fig. 7 and 8, both ends of the first rotating arm 340 are rotatably connected to the loading plate 310 and the first housing 210, respectively, and both ends of the second rotating arm 350 are rotatably connected to the loading plate 310 and the second housing 220, respectively. Further, a side of the first rotating arm 340 facing away from the display screen 100 may be smoothly transitioned by an arc surface, so that at least a portion of the cross section of the first rotating arm 340 is substantially an elliptical arc. Similarly, the side of the second rotating arm 350 facing away from the display screen 100 may also be smoothly transitioned with a curved surface, so that the cross section of the second rotating arm 350 has at least a portion substantially in the shape of an elliptical arc. In other embodiments, the cross-section of the first rotating arm 340 and the cross-section of the second rotating arm 350 can be other similar curves.
Referring to fig. 9, 10 and 11, when the foldable mobile terminal 10 is switched between the unfolded state and the folded state, the first housing 210 can drive the first cover 320 to rotate relative to the supporting plate 310, and the first housing 210 slides and stretches relative to the first cover 320, and the second housing 220 can drive the second cover 330 to rotate relative to the supporting plate 310, and the second housing 220 slides and stretches relative to the second cover 330. Specifically, during the process of switching the folder-type mobile terminal 10 from the unfolded state to the folded state, the first housing 210 can slide relative to the first cover 320, the second housing 220 can slide relative to the second cover 330, and the length of the housing assembly 200 can be extended adaptively. During the process of switching the foldable mobile terminal 10 from the folded state to the unfolded state, the first housing 210 can slide relative to the first cover 320, the second housing 220 can slide relative to the second cover 330, and the length of the housing assembly 200 can be adaptively shortened.
Since the first housing 210 can slide and extend relative to the first cover 320, and the second housing 220 can slide and extend relative to the second cover 330, during the unfolding and folding processes of the foldable mobile terminal 10, the length of the housing assembly 200 can be adaptively increased or decreased to meet the length difference change between the display screen 100 and the housing assembly 200, thereby enabling the foldable mobile terminal 10 to be smoothly unfolded and folded.
Referring to fig. 1 and 2, in an embodiment, the foldable mobile terminal 10 is substantially rectangular in shape when in the unfolded state, and a coordinate system can be established with reference to the unfolded state of the foldable mobile terminal 10, and the length direction of the foldable mobile terminal 10 is defined as an x-axis, the width direction is defined as a y-axis, and the thickness direction is defined as a z-axis. Referring to fig. 5 and 6 together, the first rotating arm 340 and the second rotating arm 350 are spaced apart in the y-axis direction, and the first rotating arm 340 and the second rotating arm 350 are disposed in pairs, i.e., one first rotating arm 340 and one second rotating arm 350 constitute one pair. For example, in the embodiment shown in fig. 5 and 6, the folding mobile terminal 10 includes two first rotating arms 340 and two second rotating arms 350, and may be formed in two pairs in the above-mentioned manner, wherein one pair is disposed at one end of the loading plate 310 and the other pair is disposed at the other end of the loading plate 310. Taking one pair as an example, the first rotating arm 340 is closer to the edge of the display 100 than the second rotating arm 350 in the width direction of the folding mobile terminal 10. Of course, in other embodiments, the folding mobile terminal 10 may be provided with only one first rotating arm 340 and one second rotating arm 350, which are respectively disposed at both ends of the loading plate 310. Alternatively, the folder-type mobile terminal 10 may be provided with more than two pairs of the first and second rotating arms 340 and 350.
In one embodiment, the display 100 is flattened when the foldable mobile terminal 10 is fully unfolded, and the foldable mobile terminal 10 has a large-screen display effect. Referring to fig. 3, in the closed state, the first casing 210 is stacked on the second casing 220, and the display screen 100 is sandwiched between the first casing 210 and the second casing 220. Specifically, referring to fig. 12, 13 and 14, the display screen 100 is a flexible screen, the flexible screen includes a bendable portion 110 and planar regions 120 connected to two sides of the bendable portion 110, and a reference zero position of an angle is a flat state of the flexible screen, and since the flexible screen has a limited bending radius, an included angle of the planar regions 120 on two sides of the bendable portion 110 of the flexible screen may be an acute angle when the folding mobile terminal 10 is folded, or the planar regions 120 on two sides are parallel to each other. Of course, in other embodiments, the Display screen 100 may include two LCD (Liquid Crystal Display) screens, the two LCD screens are respectively connected to the first casing 210 and the second casing 220, and the two LCD screens are connected by a flexible material such as silica gel to facilitate bending. Alternatively, the display screen 100 may include two OLED (organic light-Emitting Diode) screens, the two OLED screens are respectively connected to the first casing 210 and the second casing 220, and the two OLED screens are connected by a flexible material such as silica gel to facilitate bending.
Referring to fig. 12, 13, 14 and 15, a geometrical plane perpendicular to the width direction (y-axis direction) of the folder type mobile terminal 10 is made, and this geometrical plane is taken as a reference plane. Of course, the above-mentioned reference plane may also be obtained by using the rotation axis of the first cover plate 320 or the second cover plate 330 as a reference and making a geometric plane perpendicular to the rotation axis of the first cover plate 320 or the second cover plate 330. In the closed state, orthographic projections of the first swivel arm 340 and the second swivel arm 350 on a reference plane intersect. When the cross section of the first rotating arm 340 is substantially in the shape of an elliptical arc, the cross section of the second rotating arm 350 is substantially in the shape of an elliptical arc, or other similar curves, in the closed state, the sides of the first rotating arm 340 and the second rotating arm 350 facing the display screen 100 may be closer to the display screen 100 to form a receiving space adapted to the bent shape of the display screen 100, and the distance between the end of the first rotating arm 340 connected to the first housing 210 and the end of the second rotating arm 350 connected to the second housing 220 may be smaller. The curved first pivoting arm 340 and the curved second pivoting arm 350 may form a smaller opening width in the closed state, and thus may make the arrangement of parts more compact so that the folding mobile terminal 10 has a thinner thickness in the closed state.
In the folding mobile terminal 10 above, since the orthographic projections of the first rotating arm 340 and the second rotating arm 350 on the reference plane intersect when in the folded state, the arrangement is such that the accommodation space for accommodating the bendable portion 110 of the flexible screen formed when the first rotating arm 340 and the second rotating arm 350 are in the folded state is small, thereby facilitating compact arrangement of parts of the folding mobile terminal 10 and thickness reduction of the folding mobile terminal 10 when in the folded state. Since both ends of the first rotating arm 340 rotate with respect to the first housing 210 and the loading plate 310, respectively, and both ends of the second rotating arm 350 rotate with respect to the second housing 220 and the loading plate 310, respectively, during the rotation of the folding mobile terminal 10, the above structure can prevent the flexible screen from sliding with respect to the first housing 340 or the second housing 350, so as to reduce the tensile stress of the housing assembly 200 to the flexible screen, and prevent the flexible screen from being pulled and deformed during the rotation, thereby prolonging the service life of the flexible screen.
Referring again to fig. 5 and 6, in one embodiment, the folding mechanism 300 includes a first rotating shaft 312 and a second rotating shaft 313 rotatably connected to the loading plate 310, a first rotating arm 340 connected to the second rotating shaft 313, and a second rotating arm 350 connected to the first rotating shaft 312. The first rotating arm 340 can rotate relative to the carrier plate 310 by the second rotating shaft 313, and the second rotating arm 350 can rotate relative to the carrier plate 310 by the first rotating shaft 312. Further, the folding mechanism 300 includes a third rotating shaft 314 and a fourth rotating shaft 315 connected to the carrier plate 310, a first gear 316 connected to the first rotating shaft 312, a second gear 317 connected to the second rotating shaft 313, a third gear 318 connected to the third rotating shaft 314, and a fourth gear 319 connected to the fourth rotating shaft 315, wherein the first gear 316 and the fourth gear 319 are respectively engaged with the third gear 318, and the second gear 317 is engaged with the fourth gear 319. The first housing 210 can rotate the second gear 317 via the first rotating arm 340, and the second housing 220 can rotate the first gear 316 via the second rotating arm 350. The folding mechanism 300 of the above structure can achieve the synchronous rotation of the first housing 210 and the second housing 220.
Specifically, in an embodiment, the first gear 316, the second gear 317, the third gear 318, and the fourth gear 319 are incomplete gears, the first gear 316 is fixedly connected to the first rotating shaft 312, the second gear 317 is fixedly connected to the second rotating shaft 313, the third gear 318 is fixedly connected to the third rotating shaft 314, and the fourth gear 319 is fixedly connected to the fourth rotating shaft 315. The first gear 316 may be integrally formed with or detachably coupled to the first shaft 312, the second gear 317 may be integrally formed with or detachably coupled to the second shaft 313, the third gear 318 may be integrally formed with or detachably coupled to the third shaft 314, and the fourth gear 319 may be integrally formed with or detachably coupled to the fourth shaft 315. The first rotating shaft 312, the second rotating shaft 313, the third rotating shaft 314, and the fourth rotating shaft 315 are respectively rotatably connected to the carrier plate 310. The first rotating arm 340 is fixedly connected to the second rotating shaft 313, and the second rotating arm 350 is fixedly connected to the first rotating shaft 312. The first housing 210 can drive the second gear 317 to rotate through the first rotating arm 340 and the second rotating shaft 313, and further drive the fourth gear 319 and the fourth rotating shaft 315 to rotate, the second housing 220 can drive the first gear 316 to rotate through the second rotating arm 350 and the first rotating shaft 312, and further drive the third gear 318 and the third rotating shaft 314 to rotate, and further realize the synchronous rotation of the first housing 210 and the second housing 220.
Of course, in other embodiments, the third gear 318 is rotatably connected to the third rotating shaft 314, and the third rotating shaft 314 is fixedly connected to the bearing plate 310; the fourth gear 319 is rotatably connected to the fourth rotating shaft 315, and the fourth rotating shaft 315 is fixedly connected to the bearing plate 310. Compared with a structure that both ends of the third rotating shaft 314 and the fourth rotating shaft 315 bear and rotate, the above arrangement can realize the separation of the bearing function and the rotating function, thereby enhancing the stability of the structure and preventing the third rotating shaft 314 or the fourth rotating shaft 315 from being damaged due to excessive rotating force.
Referring to fig. 18, the folder-type mobile terminal 10 may further include a damping member 400, the damping member 400 being connected to the folder mechanism 300, the damping member 400 being capable of changing the rotational damping of the housing member 200 when the folder-type mobile terminal 10 is switched between the unfolded state and the folded state. Specifically, referring to fig. 18, the damping assembly 400 includes an elastic member 410 sleeved on the first rotating shaft 312, a moving cam 420 sleeved on the first rotating shaft 312 and capable of sliding along the first rotating shaft 312, and a fixed cam 430 fixedly connected to the bearing plate 310 (refer to fig. 5 and 6). One end of the elastic member 410 abuts the first rotating shaft 312 and the other end abuts the moving cam 420. Of course, the elastic member 410 may have one end abutting the carrier plate 310 and the other end abutting the movable cam 420. In one embodiment, the resilient member is a spring. When the foldable mobile terminal 10 is switched between the unfolded state and the folded state, the second housing 220 drives the first rotating shaft 312 to rotate relative to the supporting plate 310 through the second rotating arm 350, and the first rotating shaft 312 drives the movable cam 420 to rotate and abut against the fixed cam 430. The elastic member 410 is in a compressed state to enable the movable cam 420 to press the fixed cam 430, and the friction between the movable cam 420 and the fixed cam 430 can be used for immediate positioning of the first housing 210 and the second housing 220 during the unfolding and folding of the folder type mobile terminal 10. Of course, it is understood that the damping member 400 may be disposed on the second rotating shaft 313, the third rotating shaft 314, or the fourth rotating shaft 315 to achieve the clicking effect of the folding mobile terminal 10 during the unfolding and folding processes.

The cooperation of the first protrusion 421 and the second protrusion 431 can be used to achieve the click-on positioning effect at a specific angle. For example, by designing the start and end positions of the first and second protrusions 421 and 431, the movable cam 420 slides along the first rotation shaft 312 at the start and end positions, so that the pressing force of the movable cam 420 against the fixed cam 430 is abruptly reduced, thereby providing a clear and timely feedback to the user. For example, the plurality of first protrusions 421 or the plurality of second protrusions 431 may be disposed to provide a clear and timely pause feeling when the two planar regions 120 of the display screen 100 form an included angle of 30 degrees, an included angle of 60 degrees, an included angle of 90 degrees, or an included angle of 120 degrees.
