Description

Electronic device and hinge device thereof

Technical Field

The present utility model relates to a hinge, and more particularly to a link hinge suitable for flexible display.

Background

Referring to fig. 14, two bodies 91 of a conventional folding screen mobile phone are connected by a hinge 92, and a sheet-like flexible display 93 is disposed on an operation side 911 of the bodies 91. In use, the operating side 911 of the body 91 and a side 921 of the hinge 92 together form a large-area plane for use (not shown in the usage status diagram); when not in use, the two bodies 91 can be folded and turned towards each other to facilitate storage.

In order to avoid the flexible display 93 being bent to form a crease when being folded, the middle section 931 of the flexible display 93 is not adhered and fixed on an upper surface 921 of the hinge 92, so that the middle section 931 has a larger radius of curvature when being turned over and folded.

However, the middle section 931 is located at the inner side of the hinge in the folded state, so that the middle section 931 is inevitably pressed by the body 91 and the hinge 92 after being bent and cannot be naturally stretched (the middle section 931' which is naturally stretched is shown by the imaginary line), and thus the flexible display 93 is inevitably creased due to the pressing.

Therefore, the folding screen mobile phone of the prior art needs to be improved.

Detailed Description

The technical means adopted by the utility model to achieve the preset aim are further described below by matching with the drawings and the preferred embodiments of the utility model.

Referring to fig. 1 to 4, a hinge device 1 of the present utility model is used to form an electronic device with two bodies 2; the electronic device is preferably a folding screen phone and preferably has two hinges 1. Each hinge device 1 comprises a hinge base 10, two machine body connecting bases 20, a lifting supporting plate 30 and a linkage mechanism 40; and in this embodiment, further comprises two inclined support plates 50.

The hinge base 10 in this embodiment includes an elongated housing 11, and a first block 12 and a second block 13 locked thereon; in other embodiments, the hub 10 may be an integrally formed single piece.

Referring to fig. 3 to 5, the two body connecting seats 20 are respectively located opposite to the hinge seat 10 and are respectively connected to a body 2, and a chute 21 and an arc-shaped guiding portion 22 are formed on each body connecting seat 20. The lifting support plate 30 is located directly above the hinge base 10, and a plurality of long guide holes 31 (as shown in fig. 5) are formed in the lifting support plate 30, and the long guide holes 31 preferably extend in parallel along the direction of the two body connecting bases 20.

The linking mechanism 40 is disposed on the hinge base 10, and the linking mechanism 40 is connected to the two body connecting bases 20, so that the two body connecting bases 20 can be turned over, folded or opened relative to the hinge base 10. The linkage mechanism 40 is connected with the lifting support plate 30, so that the lifting support plate 30 moves towards the hinge base 10 along with the turning and folding of the two body connecting bases 20, that is, the interval distance between the lifting support plate 30 and the hinge base 10 is gradually reduced in the turning and folding process.

The linkage mechanism 40 includes two shafts 41 (shown in fig. 5), two first flipping links 42, two lifting links 43, and preferably two tilt guides 44, two second flipping links 45, and two setting members 46 (shown in fig. 5).

The shaft 41 can be rotatably disposed on the hinge base 10 by itself. Specifically, the shaft 41 is rotatably inserted through the second block 13, and the two shafts 41 are parallel to each other and connected to each other by a plurality of gears so that the two shafts 41 rotate in opposite directions in synchronization. Each shaft 41 has a rotation stop surface 411 formed thereon.

The two ends of each first flip link 42 are a first end and a second end respectively: the first end is pivoted to the hinge base 10, and specifically, the first end is connected to one of the shafts 41, and the hinge base 10 is pivoted through the shaft 41. The second end of the first flip link 42 is connected to one of the body connecting seats 20, and specifically, an elongated guiding portion 421 (as shown in fig. 5) is formed on the second end in a protruding manner, and the guiding portion 421 is slidably disposed in a straight line through the sliding slot 21 of the corresponding body connecting seat 20.

Referring to fig. 6 and fig. 8 to fig. 11, a lifting driving portion 422 is formed on each first flip link 42, and the lifting driving portion 422 is deviated from the pivot axis of the corresponding first flip link 42 relative to the hinge base 10, so that the distance between the lifting driving portion 422 and the hinge base 10 varies with the angle of the first flip link 42. In the present embodiment, the lifting driving portion 422 is formed on both the first flipping link 42, but this is not a limitation, and the lifting driving portion 422 may be formed on at least one first flipping link 42.

One end of each lifting link 43 is pivoted to the lifting driving portion 422 of one of the first turning links 42, and the other end of each lifting link 43 slidably passes through one of the guiding elongated holes 31 on the lifting support plate 30, but the connection manner between the other end of the lifting link 43 and the lifting support plate 30 is not limited thereto, and for example, the lifting support plate 30 may be pivoted. The connection positions of the two lifting connecting rods 43 and the lifting supporting plate 30 are spaced and oppositely arranged, and one side edge of each lifting connecting rod 43 can be abutted against the rotation stopping plane 411 on the shaft rod 41 connected with the corresponding first turning connecting rod 42, so that the lifting connecting rod 43 cannot rotate, and the lifting supporting plate 30 cannot move left and right relative to the pivot seat 10 in a specific state (as shown in fig. 11).

Referring to fig. 4, 5, 12 and 13, each inclined guide 44 is disposed through a second end of one of the first flipping links 42. The two ends of each second turning link 45 are respectively pivoted to the hinge base 10 and one of the body connecting bases 20, and the pivot axis of each second turning link 45 relative to the hinge base 10 is deviated from the pivot axis of any first turning link 42 relative to the hinge base 10.

In the present embodiment, the pivotal connection between the second flip link 45 and the hinge base 10 is not achieved by a solid spindle, but an arc-shaped guiding groove 451 is formed at one end of the second flip link 45, and an arc-shaped protrusion 14 with the same radius of curvature is formed on the hinge base 10, the arc-shaped protruding part 14 is slidably inserted into the arc-shaped guiding groove 451 through the angle extending block 47, so that the second turning connecting rod 45 rotates around a virtual axis defined by the arc-shaped guiding groove 451 and the radius of curvature of the arc-shaped protruding part 14, that is, the second turning connecting rod 45 is pivoted to the pivot seat 10 through a virtual rotating shaft above the pivot seat 10; it can also be said that the second flip link 45 is rotatably connected to the pivotal base 10. The pivoting manner of the second flip link 45 and the hinge base 10 is conventional, so only a brief description will be provided herein.

Referring to fig. 6-9, two setting assemblies 46 are disposed on the two shafts 41, respectively, so that the shafts 41 tend to stay at one or more specific angles during rotation. Each setting element 46 is connected to one of the shafts 41 and comprises a concave wheel 461, a cam 462 and an elastic element 463.

The concave wheel 461 is formed on the hinge base 10, and at least one setting groove 4611 is formed on the concave wheel 461. The cam 462 is slidably and non-rotatably provided on the corresponding shaft 41 along the axial direction of the shaft 41, and at least one positioning protrusion 4621 is formed on the cam 462. The elastic member 463 drives the cam 462 to slide towards the corresponding concave wheel 461, so that the setting protrusion 4621 engages with the setting groove 4611, thereby limiting the rotation of the cam 462 and further limiting the rotation of the corresponding shaft 41 relative to the hinge base 10. By properly adjusting the spring force of the resilient member 463 and the shape of the concave wheel 461 and the cam 462, the setting element 46 can cause the shaft 41 to tend to stay at a fully extended angle (as shown in fig. 8) and a fully retracted angle (as shown in fig. 9).

Referring to fig. 4, 10 and 13, the two inclined support plates 50 are respectively disposed on the two body connecting seats 20 in a tiltable manner; specifically, the bottom surface of the inclined support plate 50 is formed with a guide arc groove 51 slidably sleeved outside the arc guide portion 22 of the body connection base 20 so that the inclined support plate 50 can rotate at a small angle with respect to the body connection base 20. Each of the inclined support plates 50 is formed with an inclined guide long hole 52, and the inclined guide 44 of the interlocking mechanism 40 slidably penetrates the inclined guide long hole 52, so that the angle between the inclined support plate 50 and the corresponding body connecting seat 20 is changed along with the pivoting of the first tilting link 42.

The hinge device 1 has an unfolded state (as shown in fig. 10 and 12) and a folded state (as shown in fig. 11 and 13). In the unfolded state, each inclined support plate 50 is parallel to the corresponding machine body connecting seat 20, and the two inclined support plates 50 are flush with the lifting support plate 30, so as to form a plane together. In the process of folding the hinge device 1, the inclined guide member 44 pushes against the hole wall of the inclined guide slot 52 to drive the inclined support plate 50 to gradually incline relative to the body connecting seat 20, so that the inclined support plate 50 is not parallel to the corresponding body connecting seat 20 in the folding state.

Referring to fig. 10 and 11, specifically, the tilting of the tilting support plate 50 in the folded state makes the tilting support plate 50 closer to the body connecting seat 20 toward one side 53 of the hinge seat 10, that is, the tilting of the tilting support plate 50 in the folded state makes the distance between the two tilting support plates 50 near the hinge seat 10 greater than that in the non-tilted state. In other words, if the two inclined support plates 50 are always parallel to the body connecting seat 20, a slender square space is formed between the two inclined support plates 50 in the folded state, but a receiving space with a width gradually increasing toward the hinge seat 10 is formed between the two inclined support plates 50 in the folded state due to the inclination of the two inclined support plates 50.

Referring to fig. 1, 2, 10 and 11, two bodies 2 of the electronic device of the present utility model are preferably connected by two hinges 1 to be able to be folded or unfolded relatively, and the electronic device is preferably a folding screen mobile phone with a flexible display S, and two sides of the flexible display S are respectively fixed on the upper surfaces of the two bodies 2.

When the electronic device is turned on (as shown in fig. 1 and 10), the two hinge devices 1 are simultaneously in the unfolded state, and the lifting support plate 30 of the hinge device 1 is located between the two machine bodies 2, and an upper surface of the lifting support plate 30 is flush with an upper surface of each machine body 2 and an upper surface of each inclined support plate 50, so that the upper surfaces of the elements together form a large-area plane to serve as a support surface of the flexible display S.

When the electronic device is turned over and folded (as shown in fig. 2 and 11), the two hinge devices 1 are simultaneously in the folded state, and the lifting support plate 30 moves towards the hinge base 10 at this time, so as to increase the inner space after bending, so that the flexible display S can still be naturally stretched when being turned over and folded, and the occurrence of creases on the flexible display S is avoided. Meanwhile, a ladder-shaped space with gradually increased width toward the hinge base 10 is formed between the two inclined support plates 50, and the inner space is further increased so that the flexible display S can be naturally unfolded.

In summary, in the present utility model, by further disposing a lifting support plate 30 on the hinge device 1, and the linking mechanism 40 drives the lifting support plate 30 to move toward the hinge base 10 (i.e. reduce the distance between the lifting support plate 30 and the hinge base 10) during the overturning and folding process, so as to increase the internal accommodating space formed between the two body connecting bases 20 and the lifting support plate 30 after overturning and folding, so that the middle section of the flexible display S can still be naturally stretched in the overturning and folding state, and the flexible display S is prevented from being folded due to extrusion.

The present utility model is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any person skilled in the art can make some changes or modifications to the equivalent embodiments without departing from the scope of the technical solution of the present utility model, but any simple modification, equivalent changes and modifications to the above-mentioned embodiments according to the technical substance of the present utility model are still within the scope of the technical solution of the present utility model.
