As shown in fig. 1 to 4, an embodiment of the present disclosure provides a folding mechanism 100, which is applied to fold a display screen, and the folding mechanism 100 includes: a first rotating member 10, a second rotating member 20, and a rebound assembly 30. The first rotating member 10 includes a first connecting portion 11, a first gear 12, and a first cam 13, which are integrally formed, the first gear 12 and the first cam 13 are coaxially disposed, and the first connecting portion 11 is used for connecting with a first screen (not shown) of the foldable display screen.
The second rotating member 20 includes a second connecting portion 21, a second gear 22 and a second cam 23, which are integrally formed, and the second gear 22 is coaxially disposed with the second cam 23, and the second connecting portion 21 is used for connecting with a second screen (not shown) of the foldable display screen. The first and second panels of the foldable display screen can rotate relatively, when the first and second panels rotate relatively, the second gear 22 is directly or indirectly connected with the first gear 12 in a transmission way, so that the second rotating part 20 rotates synchronously with the first rotating part 10, and the rotating directions are opposite.
In the embodiment of the present disclosure, the relative rotation of the first screen and the second screen may be understood as the folding and unfolding of the foldable display screen, and the first reverse direction is, for example, the direction in which the first cam 13 rotates when the foldable display screen is unfolded.
In the implementation of the present disclosure, by providing the integrally formed first rotating member 10 and the integrally formed second rotating member 20, when the first screen and the second screen rotate relatively, the first screen and the first rotating member 10 rotate synchronously, and the second screen and the second rotating member 20 rotate synchronously, so as to improve the folding effect of the folding mechanism 100. The folding mechanism 100 achieves the hovering purpose during the folding process by the resilience provided by the elastic member 31.
Specifically, in the first rotating member 10, the first connecting portion 11 is provided at the peripheral side portion of the first gear 12, and the first connecting portion 11 extends in the axial direction of the first gear 12, for example, in the embodiment shown in fig. 3, the first connecting portion 11 extends in the direction of the upper bracket 40. In the embodiment of the present disclosure, one end of the first connecting portion 11 and the first gear 12 are integrally formed, and the other end of the first connecting portion 11 may be connected to the first screen along an axial extending portion of the first gear 12, so as to achieve synchronous rotation with the first screen. Based on the same concept, the second connecting portion 21 is disposed at the circumferential side portion of the second gear 22, and the second connecting portion 21 extends in the axial direction of the second gear 22, and the extending portion of the second connecting portion 21 may be connected with the second screen to achieve the synchronous rotation with the second screen.
As shown in fig. 3, the folding mechanism 100 further includes: a first transmission gear 14 and a second transmission gear 24, wherein the first transmission gear 14 is meshed with the first gear 12, and the second transmission gear 24 is meshed with the first transmission gear 14 and the second transmission gear 22 respectively. For example, the first drive gear 14 and the first gear 12 are provided with mating engagement features, by which the first drive gear 14 engages the first gear 12. Similarly, the second transmission gear 24 is provided with a meshing feature matching with the first transmission gear 14 and the second transmission gear 22, and the second transmission gear 24 is meshed with the first transmission gear 14 and the second transmission gear 22 respectively through the matching meshing feature, so as to realize synchronous rotation of the first rotating member 10 and the second rotating member 20 when the first screen and the second screen rotate relatively.
In the embodiment of the present disclosure, the first transmission gear 14 and the second transmission gear 24 are provided as transition gears to realize the synchronous linkage of the first gear 12 and the second gear 22, and further realize the synchronous linkage of the first rotating member 10 and the second rotating member 20. For example, when the folding mechanism 100 of the embodiment of the present disclosure is used for folding a thicker folding display, in the case that the sizes of the first gear 12 of the first rotating member 10 and the second gear 22 of the second rotating member 20 are smaller, the transition gear is provided to enable the first rotating member 10 and the second rotating member 20 to rotate synchronously while keeping the overall thicknesses of the folding mechanism 100 and the folding display unchanged. When the thickness of the foldable display screen is further increased, the number of the transition gears can be increased without increasing the size of the first gear 12 and the second gear 22, and the purpose of synchronous rotation of the first rotating member 10 and the second rotating member 20 is achieved while maintaining the thickness of the whole of the folding mechanism 100 and the foldable display screen.
In other embodiments of the present disclosure, the folding mechanism 100 is applied to a thinner folding display screen, and the first gear 12 and the second gear 22 do not need to be disposed therebetween, for example, as a transition gear, the first transmission gear 14 and the second transmission gear 24. For example, the first gear 12 and the second gear 22 are respectively provided with a matching engaging feature, and when the first screen and the second screen rotate relatively, the first gear 12 and the second gear 22 are engaged through the engaging feature, so that the first rotating member 10 and the second rotating member 20 rotate synchronously. In the embodiment of the present disclosure, the first rotating member 10 and the second rotating member 20 are synchronously rotated by the direct engagement of the first gear 12 and the second gear 22, and the stability of the synchronous rotation of the first rotating member 10 and the second rotating member 20 can be improved relative to the indirect transmission connection of the first gear 12 and the second gear 22.
Further, the folding mechanism 100 of the disclosed embodiment further includes a first rotating block 50 and a second rotating block 60. Wherein, first rotatory piece 50 is connected with first connecting portion 11 transmission to with first screen fixed connection, in order to realize the rotation of first screen through the rotation of first rotatory piece 50. The second rotating block 60 is in transmission connection with the second connecting portion 21 and is fixedly connected with the second screen to realize rotation of the second screen through rotation of the second rotating block 60.
In the embodiment of the present disclosure, the transmission connection between the first rotating block 50 and the first connecting portion 11 and the transmission connection between the second rotating block 60 and the second connecting portion 21 may be implemented by respectively providing sliding grooves on the first rotating block 50 and the second rotating block 60, which are matched with the first connecting portion 11 and the second connecting portion 21. The sliding groove on the first rotating block 50 is used for accommodating the first connecting portion 11, the sliding groove on the second rotating block 60 is used for accommodating the second connecting portion 21, and when the first rotating block 50 and the second rotating block 60 rotate relatively, the first connecting portion 11 correspondingly slides in the sliding groove of the first rotating block 50 to match the rotation of the first rotating block 50, and the second connecting portion 21 correspondingly slides in the sliding groove of the second rotating block 60 to match the rotation of the second rotating block 60, so that the purpose that the first rotating member 10 and the first rotating block 50, and the second rotating member 20 and the second rotating block 60 synchronously rotate is achieved.
The folding mechanism 100 of the embodiment of the present disclosure further includes an upper bracket 40, and the first rotating block 50 and the second rotating block 60 are disposed on the upper bracket 40 and can rotate relative to the upper bracket. In the embodiment of the present disclosure, the first rotating block 50 and the second rotating block 60 are symmetrically disposed on the upper bracket 40 to keep the balance of the folding mechanism 100, and when the folding mechanism 100 is used to fold a folded display screen, the display screen can be symmetrically folded, thereby improving the stability of the display screen during the folding process.
The folding mechanism 100 of the disclosed embodiment further includes: one end of the elastic member 31 is fixed to the lower bracket 70, and the other end is fixed to the moving member 32. For example, in the embodiment shown in fig. 3, when the moving member 32 is moved toward the lower bracket 70 by the cooperation of the moving member 32 and the lower bracket 70, the moving member 32 compresses the elastic member 31. When the elastic member 31 is pressed by the moving member 32 and the lower bracket 70, a rebound stroke is generated, and thus, a rebound force is generated in the elastic member 31 and the elastic member 31 rebounds. When the elastic member 31 is rebounded, the moving member 32 moves toward the upper bracket 40.
Further, in order to improve the stability of the connection of the first and second rotating blocks 50 and 60 to the folding mechanism 100 of the embodiment of the present disclosure, the elastic member 31 of the rebound assembly 30 in the folding mechanism 100 includes a first spring 311 and a second spring 312. In the embodiment shown in fig. 3, the rebound assembly 30 further comprises a first guide rod 33 and a second guide rod 34, and one end of each of the first guide rod 33 and the second guide rod 34 is fixed to the lower bracket 70. Wherein, the first guide rod 33 passes through the first spring 311, the moving member 32, the first cam 13 and the first gear 12 in sequence; the second guide bar 34 passes through the second spring 312, the moving member 32, the second cam 23, and the second gear 22 in this order. In the embodiment of the present disclosure, both ends of the first guide rod 33 are respectively fixed to the lower bracket 70 and the upper bracket 40, and likewise, both ends of the second guide rod 34 are respectively fixed to the lower bracket 70 and the upper bracket 40, thereby improving the overall stability of the folding mechanism 100 during the folding process.
Based on the same concept, the elastic component 31 further includes one or more third springs 313, and correspondingly, the rebounding assembly 30 further includes one or more third guide rods 35, and the number of the third guide rods 35 and the number of the third springs 313 are the same, the third guide rods 35 respectively pass through the third springs 313, one end of each third guide rod 35 is fixed to the lower bracket 70, and the other end of each third guide rod 35 is fixed to the upper bracket 40. In the embodiment shown in fig. 3, the third guide rod 35 may be fixed to the upper bracket 40 after passing through the third spring 313 and the moving member 32 in sequence. Three through holes with equal intervals are formed in the moving part 32, and the first guide rod 33, the second guide rod 34 and the third guide rod 35 respectively penetrate through the three through holes. By passing the first, second, and third guide bars 33, 34, and 35, which are disposed at equal intervals, through the moving part 32, the stability of the moving part 32 moving along the first, second, and third guide bars 33, 34, and 35 may be improved.
In the embodiment of the present disclosure, the number of the third springs 313 and the third guide rods 35 is not limited to one, and it is understood that the overall stability of the folding mechanism 100 is relatively increased by relatively increasing the number of the third springs 313 and the third guide rods 35, and in the embodiment of the present disclosure, the number of the third springs 313 and the third guide rods 35 is one, so that the overall stability of the folding mechanism 100 is improved, and the size of the folding mechanism 100 is reduced, and the weight of the folding mechanism 100 is reduced.
Further, in order to make the folding mechanism 100 of the embodiment of the present disclosure achieve the hovering purpose at the time of the folding process, cam inclined surfaces are provided on the first cam 13 of the first rotating member 10 and the second cam 23 of the second rotating member 20, and a moving inclined surface abutting the cam inclined surfaces is provided at a position of the moving member 32 opposing the first cam 13 and the second cam 23.
Specifically, the inclined surfaces of the first cam 13 of the first rotating member 10 and the second cam 23 of the second rotating member 20 are gradually inclined in height in the first direction, wherein the inclined surfaces are understood to be vertical distances in the axial direction thereof. For example, in the embodiment shown in fig. 3, when the first panel and the second panel are rotated relative to each other to achieve the folded state of the folded display panel, the inclined surface of the first cam 13 abuts against the moving inclined surface of the moving member 32, and the moving member 32 moves along the first guide bar 33 toward the lower bracket 70 as the inclined height increases when the first cam abuts against the moving inclined surface. The moving member 32 moves toward the lower bracket 70 by the same distance as the vertical distance of the inclined surface in the direction of the first guide bar 33, thereby providing a rebound stroke of a corresponding distance to the first spring 311. As the inclination height when the inclined surface of the first cam 13 abuts against the movement inclined surface of the moving member 32 increases, the rebound stroke provided by the moving member 32 to the first spring 311 increases, and the rebound force provided by the first spring 311 increases.
Since the display screen is a flexible foldable display screen, due to its own flexibility, a force in a first reverse rotation, referred to herein as a first reverse rotation force, is applied to the first rotating member 10, thereby causing the first cam 13 to have a tendency to rotate in the first reverse rotation. When the first screen and the second screen relatively move to a proper position, the first spring 311 is pressed by the moving component 32 to generate a resilience force, the resilience force of the first spring 311 and the first reverse rotating force are offset at the abutting position of the inclined surface of the first cam 13, and then the first cam 13 and the moving component 32 are relatively static, so that the hovering purpose of the folding mechanism 100 is realized.
For example, FIG. 5 is a force analysis plot on a cam ramp of a folding mechanism shown in accordance with an exemplary embodiment.
As shown in fig. 5, the position where the cam inclined surface of the first cam 13 abuts against the moving member 32 is denoted by S, the repulsive force of the first spring 311 is denoted by F, and the component forces of F on the cam inclined surface are F1 and F2, respectively. Wherein F2 is perpendicular to the cam inclined plane, and F2 does not move the position of S in the direction of F2. F1 is parallel to the cam inclined surface, and the direction of F1 is the same as the direction in which the inclined height of the cam inclined surface increases, thereby moving S in the direction of F1.
When the first and second panels are relatively moved, for example, when the first cam 13 rotates in synchronization with the first panel and abuts against the moving member 32 at the S position, a first counter-rotating force (not shown) at the S position is equal to F1 in magnitude and opposite in direction, and the first cam 13 and the moving member 32 are stationary at the S position, thereby achieving the purpose of stationary rotation of the first panel.
Similarly, the inclined cam surface of the second cam 23 abuts against the moving part 32 at a position opposite to S, and the second spring 312 provides a resilient force, so as to achieve the purpose of stationary rotation of the second screen.
In the embodiment of the present disclosure, by the design of the cam inclined surfaces of the first cam 13 and the second cam 23, the resilience of the first spring 311 and the resilience of the second spring 312 are offset from the first reverse rotational force at the abutting position of the cam inclined surfaces, so that the folding mechanism 100 of the embodiment of the present disclosure achieves the hovering purpose in the folding process. Through the cam inclined plane setting, avoid adding a plurality of auxiliary gear to realize hovering of folding mechanism 100 in order to increase the size and the dead weight of folding mechanism 100, improve the effect of hovering of folding mechanism 100 of the embodiment of this disclosure, improve folding mechanism 100's lightness nature simultaneously.
Further, in the embodiments of the present disclosure, the folding arc of the flexible display screen may be specifically defined based on the actual use requirement of the flexible display screen. For example, in the embodiment of fig. 3, the folding arcs of the first and second panels of the flexible display screen are synchronously folded by the rotation of the first and second rotation blocks 50 and 60, and the rotation directions of the first and second rotation blocks 50 and 60 are opposite. Further, an arc-shaped slot (not shown) may be disposed on the upper bracket 40, and an arc-shaped sliding rail (not shown) corresponding to the arc-shaped slot may be disposed on the first rotating block 50 and the second rotating block 60, and the arc-shaped sliding rail may slide in the arc-shaped slot in a certain arc. The radian of the arc-shaped groove can be set based on the flexibility of the flexible display screen, and also can be set based on actual requirements, and is not specifically limited here. Through setting up matched with arc wall and arc slide rail, make first rotatory piece 50 and the rotatory rotation that carries out certain radian of second 60 to avoid flexible display screen to be hindered at folding in-process.
Similarly, a limiting structure may be provided on the first cam 13 and the second cam 23 to protect the folding mechanism 100 from folding. For example, in the embodiment shown in fig. 1, the first cam 13 is provided with a first stopper 131, and the second cam 23 is provided with a second stopper 231. The first stopper 131 of the first cam 13 is engaged with the first frame 71 of the lower bracket 70 to restrict the rotational position of the first rotary block 50, and the second stopper 231 of the second cam 23 is engaged with the second frame 72 of the lower bracket 70 to restrict the rotational position of the second rotary block 60.
For example, in the free state, the first rotating block 50 and the second rotating block 60 are symmetrically distributed on the upper bracket 40 and are in the same horizontal plane, that is, when the first screen and the second screen of the flexible display screen are fixedly connected to the first rotating block 50 and the second rotating block 60, respectively, the flexible display screen is in the horizontal state.
When the flexible display panel is folded, the first position-limiting member 131 rotates towards the second frame 72, and does not contact with the lower bracket 70 during the rotation, and the second position-limiting member 231 rotates towards the first frame 71, and does not contact with the lower bracket 70 during the rotation. Wherein, the first and second limiting parts 131 and 231 may be provided as continuous inclined surfaces, and the increasing direction of the inclination of the continuous inclined surfaces on the first and second limiting parts 131 and 231 is the same as the rotating direction of the first and second rotating blocks 50 and 60, respectively.
When the flexible display screen is changed from the folded state to the unfolded state and the flexible display screen is in the horizontal state, the first limiting member 131 limits the first rotating block 50 to continue rotating, and the second limiting member 231 limits the second rotating block 60 to continue rotating, so that the first rotating block 50 and the second rotating block 60 can be prevented from continuing rotating to cause damage to the folding mechanism 100, and the folding mechanism 100 can be protected.
In the embodiment of the present disclosure, the position of the first limiting member 131 on the first cam 13 and the position of the second limiting member 231 on the second cam 23 may be set according to specific requirements, and are not specifically limited herein.
Based on the same concept, the embodiment of the present disclosure also provides a terminal device, which includes a foldable display screen and the folding mechanism 100 in the embodiment of the present disclosure. The folding display screen comprises a first screen and a second screen which can rotate relatively, and the folding of the folding display screen is realized through the relative rotation of the first screen and the second screen.
For example, the terminal device of the embodiment of the present disclosure may be a mobile phone, a computer, etc., taking a folding screen mobile phone as an example. In the folding screen mobile phone, the first screen and the second screen of the folding screen mobile phone are symmetrically folded, and after the folding screen mobile phone is folded, a user can make and receive calls or process simple text information and the like without unfolding the display screen of the folding screen mobile phone. When a user needs to process office documents, read electronic books or watch videos, the display screen of the folding screen mobile phone can be unfolded, so that large-screen display and display of information of the folding screen mobile phone can be realized, and the experience effect of the user is improved. When the user unfolds the folding screen mobile phone, the display screen of the folding screen mobile phone can be folded at a proper position according to the actual requirement of the user, and the secrecy of information displayed by the display screen can be improved.
It should be noted that the relevant components in the folding mechanism 100 in the embodiment of the present disclosure may be symmetrically disposed, for example, the first rotating block 50 and the second rotating block 60 are disposed in pairs on the upper bracket 40.
In other embodiments of the present disclosure, the terminal device may be a notebook computer, and the related components in the folding mechanism 100 may not be limited to a symmetrical arrangement, for example, the folding mechanism 100 is provided with the first rotating block 50, the first rotating member 10, the first spring 311, the first guide rod 33, and the like, the folding mechanism 100 is disposed at a connection position between a display screen of the notebook computer and a keyboard, and the display screen of the notebook computer is fixedly connected to the first rotating block 50. The position of the display screen of the notebook computer can be adjusted by rotating the first rotating block 50, and when the display screen of the notebook computer is adjusted to a proper position, the display screen of the notebook computer can be hovered at the corresponding position. The specific application of the folding mechanism 100 of the disclosed embodiment is not specifically limited herein.
