Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application.
Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
An electronic device as shown in fig. 1, 2, 12, and 13 includes a first housing 600, a second housing 700, a flexible screen 800, and a folding mechanism. The first casing 600 and the second casing 700 are respectively arranged at two sides of the folding mechanism, the flexible screen 800 is connected to the first casing 600 and the second casing 700 and covers the folding mechanism, and the flexible screen 800 is supported by the whole formed by the first casing 600, the folding mechanism and the second casing 700.
In a specific use process, the electronic device may be unfolded when the folding mechanism is unfolded so that the first casing 600 and the second casing 700 are coplanar with each other, the electronic device may be folded when the folding mechanism is folded so that the first casing 600 and the second casing 700 are overlapped with each other, and the flexible screen 800 will be unfolded or folded along with the movement of the folding mechanism.
Referring to fig. 8 to 10, an embodiment of the present application discloses a folding mechanism, which includes a base 100, a first supporting mechanism 200, a second supporting mechanism 300, a rack 400, and an elastic member 500.
Wherein: the first supporting mechanism 200 is rotatably connected to a first side of the base 100, and the second supporting mechanism 300 is rotatably connected to a second side of the base 100, the first side being opposite to the second side. The first and second support mechanisms 200 and 300 are disposed on top of the folding mechanism.
The first supporting mechanism 200 includes a first engaging portion 210, the second supporting mechanism 300 includes a second engaging portion 310, the rack 400 is movably disposed on the base portion 100, the rack 400 is located between the first engaging portion 210 and the second engaging portion 310 and respectively engaged with the first engaging portion 210 and the second engaging portion 310, and the elastic member 500 is disposed between the rack 400 and the base portion 100. Specifically, the first engaging portion 210 and the second engaging portion 310 may be transmission members such as gears or shafts, and the two sides of the rack 400 have symmetrically arranged engaging teeth to realize that the rack 400 is engaged with the first engaging portion 210 and the second engaging portion 310, respectively.
The elastic member 500 may be stretched or compressed along with the movement of the rack 400 during the unfolding of the folding mechanism, and the elastic member 500 drives the rack 400 to move during the folding of the folding mechanism; alternatively, the elastic member 500 may be stretched or compressed with the movement of the rack 400 during the folding of the folding mechanism, and the elastic member 500 drives the movement of the rack 400 during the unfolding of the folding mechanism.
In the actual operation process, no matter to first supporting mechanism 200, still exert external force to second supporting mechanism 300, through rack 400 meshing transmission, can make first supporting mechanism 200 and second supporting mechanism 300 realize the linkage, and then realize that folding mechanism is comparatively steady folding or expandes, increase the convenience of folding structure operation, and then make the electronic equipment maneuverability of installation folding mechanism stronger.
And the specific location of the elastic member 500 may be, as shown in fig. 11 and 13, located in the rack 400 near the bottom of the folding mechanism. And the elastic member 500 may be set in a compressed state when the folding mechanism is folded, and the elastic member 500 may be set in a stretched state when the folding mechanism is unfolded.
When the folding mechanism is in the unfolded state, if an external force is applied to start folding the folding mechanism, the stretching deformation of the elastic member 500 at this time can be used as an assisting force to assist in driving the rack 400 to move downward, as seen in the cross section shown in fig. 11. Thus, the elastic member 500 provides a part of driving force required for rotation to the first supporting mechanism 200 and the second supporting mechanism 300 through the rack 400, so that the folding mechanism is labor-saving in the initial stage of switching from the unfolded state to the folded state.
When the folding mechanism is in the folded state, if an external force is applied to start unfolding the folding mechanism, the compression deformation of the elastic member 500 at this time can be used as an assisting force to assist the driving rack 400 to move upward, as seen in the cross section shown in fig. 13. Thus, the elastic member 500 provides a part of driving force required for rotation to the first supporting mechanism 200 and the second supporting mechanism 300 through the rack 400, so that the folding mechanism is labor-saving in the initial stage of switching from the folded state to the stretched state.
As known from the physical common knowledge, the folding mechanism will be in a balanced state in the process of not receiving external force, such as the folding mechanism keeps a folded state or an unfolded state. If the folding mechanism is switched, an external force greater than a critical value is required to be provided for the folding mechanism so as to break the original balance state of the folding mechanism, wherein the critical value is usually a static friction force or a locking force applied to an object, and the critical value is denoted as Fmax. When the balance is broken, the resistance to be overcome is reduced because the folding mechanism keeps moving all the time, wherein the resistance is the dynamic friction force of the object, and the resistance in the moving process is marked as F, wherein Fmax is larger than F. The purpose of the design of the elastic member 500 is to allow the user to switch the state of the folding mechanism by applying a smaller force.
Assuming that the driving force generated by the deformation of the elastic member 500 is t when the folding mechanism is in the folded state or the unfolded state, if the folding mechanism is to be switched between states, the driving force t is the assisting force that can be obtained by the user, then the initial external force F0 applied by the user is greater than Fmax-t, that is, through the arrangement of the elastic member 500, the user can apply a small force to break the balance state of the folding mechanism, so that the folding mechanism can be switched between states more easily, and the operation convenience of the device is improved.
In summary, the folding mechanism can realize the linkage of the first supporting mechanism 200 and the second supporting mechanism 300 through the rack 400, and the user can generate the assisting force by means of the elastic member 500 while the linkage is performed, so as to save the external force required to be applied when the state of the folding mechanism is switched, thereby improving the convenience of the user in operating the folding mechanism
In an alternative, the elastic member 500 may be disposed at an end of the rack 400 near the top of the folding mechanism, such that the elastic member 500 is placed in a stretched state when the folding mechanism is in a folded state; the above-mentioned effects can also be achieved when the elastic member 500 is in a compressed state when the folding mechanism is in an unfolded state, and will not be described in detail herein.
As another alternative, the elastic member 500 may be disposed at an end of the rack 400 close to the top of the folding mechanism and an end of the rack 400 far from the top of the folding mechanism, respectively, which will not be described in detail herein.
More specifically, the folding mechanism can be provided with a locking device to maintain the unfolded or folded state when no external force is applied, such as a damping device, a magnetic attraction device, etc., which are not described in detail herein.
Further, as shown in fig. 10 and 11, the base 100 is provided with a guide protrusion 112, and the rack 400 is provided with a bar-shaped guide hole 410. The guide protrusion 112 is slidably engaged with the strip-shaped guide hole 410 along the moving direction of the rack 400, so that the sliding engagement can restrict the moving path of the rack 400, and particularly, the rack 400 can only move up and down along the thickness direction of the folding mechanism when viewed from the cross section of fig. 10 and 11, so as to avoid deflection or displacement. Meanwhile, the sliding fit can limit the stroke of the rack 400 to prevent the rack from moving excessively, so that the rotation angle of the folding mechanism is controlled.
More specifically, strip guiding hole 410 is waist type hole, and guide protrusion 112 is waist type sand grip, and waist type hole both ends are the arc, and waist type sand grip both ends also are the arc, and when rack 400 moved to the terminal point of self stroke like this, the contact between arc and the arc was comparatively level and smooth, can prevent strip guiding hole 410 and guide protrusion 112 collision each other and collide with and damage.
In an alternative embodiment, a strip-shaped guide hole 410 may be provided on the base 100, and a guide protrusion 112 may be provided on the rack 400, so that the sliding fit between the strip-shaped guide hole 410 and the guide protrusion 112 can be achieved.
Meanwhile, the strip-shaped guide hole 410 may be replaced with a guide groove, and the rack 400 may be guided by sliding fit between the guide groove and the guide protrusion 112.
In a further embodiment, the elastic member 500 may be a telescopic spring, and the labor saving of operating the folding mechanism is achieved by the forced deformation of the telescopic spring. Of course, the elastic member 500 may be an elastic pad, an elastic strip, or the like, and may also achieve the effect of a retractable spring.
In some embodiments, as shown in fig. 8 to 11, the first supporting mechanism 200 includes a first supporting member 220 and a second supporting member 230, the second supporting mechanism 300 includes a third supporting member 320 and a fourth supporting member 330, the first supporting member 220 is provided with a first engaging portion 210, and the third supporting member 320 is provided with a second engaging portion 310.
The first supporting member 220 is rotatably engaged with the base 100 about the first axis a. The second supporting member 230 is rotatably engaged with the first supporting member 220 about the second axis B. The third supporter 320 is rotatably coupled to the base 100 about the third axis C. The fourth supporter 330 is rotatably coupled to the third supporter 320 about the fourth axis D.
Meanwhile, the second axis B is located on a side of the first axis a away from the base 100, and the fourth axis D is located on a side of the third axis C away from the base 100. Thus, the second support member 230 and the first support member 220 perform eccentric rotation, that is, the first support member 220 rotates around the first axis a, and the second support member 230 can rotate around the second axis B with the first support member 220. The third supporter 320 and the fourth supporter 330 also rotate eccentrically, that is, the third supporter 320 rotates around the third axis C, and the fourth supporter 330 can rotate around the fourth axis D with the third supporter 320.
The folding mechanism has a folded state and an unfolded state. During the folding of the folding mechanism, the first support mechanism 200 rotates relative to the base 100, and the second support mechanism 300 rotates relative to the base 100. Specifically, the first support member 220 and the third support member 320 rotate relative to the base 100, while the second support member 230 and the fourth support member 330 respectively rotate along with the first support member 220 and the third support member 320, and can further rotate relative to the first support member 220 and the third support member 320, because the second axis B is located on the side of the first axis a away from the base 100, and the fourth axis D is located on the side of the third axis C away from the base 100, after the folding is completed, a large redundant space is formed between the second support member 230 and the fourth support member 330 and the base 100, and a bending part of the flexible screen 800 in the process of following the folding can be better accommodated in the redundant space, thereby preventing the flexible screen 800 from being damaged due to the overlapping compression, and further improving the service life of the flexible screen of the electronic device.
In a more specific embodiment, as shown in fig. 1 to 3, for the electronic device with the folding mechanism installed, the first casing 600 is disposed on the same side as the first supporting mechanism 200 and is connected to a side of the first supporting mechanism 200 away from the base 100, specifically, the first casing 600 is connected to the first supporting member 220, so that the first casing 600 can rotate around the first axis a following the rotation of the first supporting mechanism 200.
The second housing 700 is disposed on the same side as the second supporting mechanism 300 and is connected to a side of the second supporting mechanism 300 away from the base 100, specifically, the second housing 700 is connected to the third supporting member 320, so that the second housing 700 can rotate around the third axis C with the second supporting mechanism 300.
As shown in fig. 8 to 11, in the unfolded state of the folding mechanism, the first casing 600 and the second support 230 both rotate following the first support 220, and the second casing 700 and the fourth support 330 rotate following the third support 320. A third screen supporting surface is arranged between the first casing 600 and the second casing 700, the flexible screen 800 is flattened, and at least part of the flexible screen 800 is supported on the third screen supporting surface formed by the first casing 600 and the second casing 700. Wherein the second and fourth supporting members 230 and 330 may form a first screen supporting surface, the first and third screen supporting surfaces are parallel to each other, and the first screen supporting surface is at a central position of the folding mechanism. Therefore, the first screen supporting surface is matched with the third screen supporting surface to unfold the flexible screen 800, and meanwhile, the flexible screen 800 can be supported in the center, so that the flexible screen 800 is prevented from collapsing in the center of the folding mechanism.
As shown in fig. 12 and 13, in the folded state, the first support 220 and the third support 320 are overlapped. While the first case 600 and the second case 700 are stacked by the first case 600 rotating with the first support 220 about the first axis a and by the second case 700 rotating with the third support 320 about the third axis C.
The first support 220 and the third support 320 are opposite to each other by the second support 230 being rotatable about the second axis B relative to the first support 220 and the fourth support 330 being rotatable about the fourth axis D relative to the third support 320.
In a more preferred embodiment, as shown in fig. 11, the base 100 includes a second screen supporting surface 113, and in the extended state, the second screen supporting surface 113, the first screen supporting surface and the third screen supporting surface are coplanar. Therefore, the second screen supporting surface 113 is matched with the first screen supporting surface to play a better central supporting effect on the flexible screen 800, and the flexible screen 800 is prevented from collapsing at the central position of the folding mechanism in the unfolding state.
In a further embodiment, as shown in fig. 4 and 11, the first support 220 comprises two first support strip-shaped plates 221 located at a first side of the base 100, the two first support strip-shaped plates 221 are respectively connected to two ends of the base 100, and the two first support strip-shaped plates 221 are rotatably matched with the base 100 by taking the first axis a as a rotation center.
The third supporting member 320 includes two second supporting strip-shaped plates 321 located on the second side of the base 100, the two second supporting strip-shaped plates 321 are respectively connected to two ends of the base 100, and the two second supporting strip-shaped plates 321 are in rotating fit with the base 100 by using the third axis C as a rotation center.
The two first supporting strip-shaped plates 221 are correspondingly engaged with the two second supporting strip-shaped plates 321, and the first supporting strip-shaped plates 221 and the second supporting strip-shaped plates 321 connected to the same end of the base 100 are engaged with each other through the corresponding first engaging portions 210 and the second engaging portions 310.
In this way, the first supporting strip-shaped plate 221 and the second supporting strip-shaped plate 321 are designed in pairs, so that the first casing 600 and the second casing 700 connected thereto can be more stable, the operability of the folding mechanism is increased, and the electronic device equipped with the folding mechanism is more comfortable.
In a more preferred embodiment, the folding mechanism is in an "I" beam configuration when in an unfolded state, as shown in FIG. 8, and has cross beams, vertical beams, and wings. The wing plates can rotate along with the cross beams and relative to the vertical beams. The first support 220 and the third support 320 constitute a cross beam, the base 100 constitutes a vertical beam, and the second support 230 and the fourth support 330 constitute a wing plate. Thus, the first shell 600 and the second shell 700 are respectively connected through the cross beam, and the flexible screen 800 is centrally supported through the wing plate matched with the vertical beam, so that the operability and experience of a user on the electronic equipment are improved.
Further, as shown in fig. 4 and 5, the first engaging portions 210 are two and located at two ends of the base portion 100, and the two first engaging portions 210 are connected by a first connecting shaft 240. The two second engaging portions 310 are respectively located at two ends of the base portion 100, and the two second engaging portions 310 are connected by a second connecting shaft 340. The number of the racks 400 is two, the two racks 400 are respectively located at both ends of the base 100, and the racks 400 are engaged with the first engaging portion 210 and the second engaging portion 310 located at the same end of the base 100.
This allows the two first supporting strip-shaped plates 221 to be linked by the first connecting shaft 240, and the two second engaging portions 310 to be linked by the second connecting shaft 340, further increasing the operability of the folding mechanism.
It should be noted that, the first meshing portion 210 and the first connecting shaft 240, and the second meshing portion 310 and the second connecting shaft 340 can be connected by a key connection, and may also be connected by other forms of hub connection, and may also be integrally formed into a gear shaft structure, and details thereof are not described here.
In some embodiments, as shown in fig. 9 and 10, the base 100 includes a housing structure portion 110, the housing structure portion 110 has a receiving space 111, the first engaging portion 210, the second engaging portion 310, the rack 400 and the elastic member 500 are disposed in the receiving space 111, and the first supporting member 220 and the third supporting member 320 are disposed outside the receiving space 111.
The housing structure 110 can protect the components that are driven, such as dust, water, and bump. The specific structure of the housing structure portion 110 may be an integrally provided housing structure, or a housing structure formed by fastening two housings adapted to each other up and down.
Further, as shown in fig. 3 and 10, the base 100 further includes two cover plates 120 respectively located at both ends of the base 100. The cover plate 120 and the housing structure portion 110 form an accommodation gap 130 therebetween. The end of the first support 220 and the end of the third support 320 are located in the receiving gap 130, and the cover plate 120 covers the end of the first support 220 and the end of the third support 320.
Thus, by designing the cover plate 120, the first support 220 and the third support 320 can be axially limited and stopped, and the first support 220 and the third support 320 are prevented from being separated from the folding mechanism along the first axis a and the third axis C, respectively. Meanwhile, the protection of the shade can be realized, and the integral attractiveness of the folding mechanism and the electronic equipment provided with the folding mechanism is improved.
It should be noted that, the covering plate 120 and the shell structure portion 110 may be integrally formed, and formed 130 by a transverse slot; the cover plate 120 and the housing structure 110 may be connected by four rotation pins, and the axes of the four rotation pins form a first axis a, a second axis B, a third axis C and a fourth axis D, respectively, which will not be described in detail herein.
In some embodiments, as shown in fig. 11 to 13, the first end of the second supporting member 230 is close to the first axis a, and the first end of the second supporting member 230 is rotatably engaged with the first supporting member 220 by taking the second axis B as a rotation center.
The first end of the fourth supporting member 330 is close to the third axis C, and the first end of the fourth supporting member 330 is rotatably engaged with the third supporting member 320 by using the fourth axis D as a rotation center.
In the folded state of the electronic device, a distance between the first end of the second support member 230 and the first end of the fourth support member 330 is a first distance a, a distance between the second end of the second support member 230 and the second end of the fourth support member 330 is a second distance b, and the first distance a is greater than the second distance b.
In this way, the second supporting member 230 and the fourth supporting member 330 are disposed opposite to each other and inclined to each other, so that the cross section of the formed redundant space is tapered, and the aperture of the redundant space is gradually increased toward the rack 400, such a design enables the folding structure to be mounted on the electronic device, the flexible screen 800 can bend at the center position of the flexible screen 800 along with the folding of the electronic device, and the bent position is accommodated in the redundant space, and by using the tapered configuration of the redundant space, the curvature radius of the bent position of the flexible screen 800 can be controlled, and the flexible screen is prevented from being damaged due to the excessive folding. In summary, the flexible screen 800 can be better protected by the redundancy design formed by the redundancy space.
Further, as shown in fig. 6, 7 and 11, the first supporting member 220 is provided with a first strip-shaped matching hole 223, and the third supporting member 320 is provided with a second strip-shaped matching hole 323. The second end of the second supporting member 230 is rotatably engaged with the first strip-shaped engaging hole 223 and can slide along the first strip-shaped engaging hole 223, and the second end of the fourth supporting member 330 is rotatably engaged with the second strip-shaped engaging hole 323 and can slide along the second strip-shaped engaging hole 323.
This design takes into account the non-concentric rotation between the first support 220 and the second support 230 (rotation about the first axis a and the second axis B, respectively), and the non-concentric rotation between the third support 320 and the fourth support 330 (rotation about the third axis C and the fourth axis D, respectively).
Thus, when the second supporting member 230 rotates along with the first supporting member 220, the first end of the second supporting member 230 keeps fixed to the first supporting member 220, and the second end of the second supporting member 230 moves relative to the first supporting member 220, so that the first strip-shaped matching hole 223 is provided, and the interference of the movement of the second end of the second supporting member 230 is avoided through the rotational matching of the first and second supporting members, and the folding mechanism is prevented from being jammed and the like. The first strip-shaped fitting hole 223 can also guide the movement of the second end of the second support member 230.
Similarly, when the third supporting member 320 and the fourth supporting member 330 rotate, the first end of the fourth supporting member 330 will remain fixed to the third supporting member 320, and the second end of the fourth supporting member 330 will move relative to the third supporting member 320, so that the second strip-shaped matching hole 323 is provided, and through the rotational matching between the first end and the second end, the interference of the movement of the second end of the third supporting member 320 is avoided, and the folding mechanism is prevented from being jammed and the like. The second bar-shaped coupling hole 323 can also guide the movement of the second end of the third supporting member 320 at the same time
