Description

Technical Field

[0001] The present invention relates to the field of electronic equipment, and in particular to a 360° hinge and a mobile terminal. Background Art

[0002] Flexible screen is a new type of screen. For external flexible screen mobile terminals with flexible screens set on the outside of the mobile terminal, it is necessary to deal with the length change caused by the closing and opening of the hinge. For the middle part of the hinge, some hinges use a structure with multiple supports to achieve support and shape changes when bending and flattening.

[0003] However, traditional flexible screen folding terminals are generally single inward-folding or outward-folding types, and the folding range is relatively limited. At the same time, the folding hinges used in the folding terminals have many complex action components, and the complicated types of action mechanisms require a lot of labor costs and time costs both in the design and manufacturing processes. In addition, during the rotation process, the traditional hinges have complex action mechanisms and poor linkage, resulting in low stability and easier damage to the supporting flexible screen, which invisibly reduces the service life of the terminal. In addition, the traditional folding hinges are also poorly adaptable to different types of mobile terminals, resulting in great limitations in the use of terminal hinges. Summary of the invention

[0004] The purpose of the present invention is to provide a 360° hinge and a mobile terminal to solve the problem that the traditional hinge proposed in the above background technology has a complex action mechanism and poor linkage during rotation, resulting in low stability and easier damage to the flexible screen used in conjunction with it, which invisibly reduces the service life of the terminal, and the traditional folding hinge has poor adaptability to different types of mobile terminals.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a 360° hinge, comprising a hinge mechanism, wherein the hinge mechanism comprises eight horizontally arranged outer steel bars, and four synchronous folding mechanisms are installed on the inner sides of the eight outer steel bars for realizing smooth synchronous rotation of the terminal shell from 0 to 360° and cooperating with the first adhesive backing plate to provide constant length support for the flexible screen, and a synchronous tooth buckle group is arranged inside the synchronous folding mechanism for the rotation cooperation of multiple rotating shafts thereof to ensure that mechanical feedback is provided when the hinge rotates smoothly, and drive the corresponding damping mechanism to rotate synchronously;

[0006] The damping mechanism is provided with a guide mechanism for compensating the folded distance of the adhesive backing plate of the hinge mechanism and providing hinge rotation damping when the hinge rotates, and the guide mechanism is provided with a connection end for connecting to the terminal housing;

[0007] The hinge mechanism also includes a left finger track and a right finger track located at both sides of the top of the synchronous folding mechanism and cooperating with the damping mechanism and the first adhesive backing plate to lock the terminal shell when it is folded.

[0008] As a preferred technical solution of the present invention, the synchronous folding mechanism includes two groups of axis one, two groups of axis two, two groups of axis three and two groups of axis four forming eight rotating shafts, and each group of axis one, axis two, axis three and axis four are symmetrically arranged and respectively arranged relative to the eight outer steel bars.

[0010] As a preferred technical solution of the present invention, there are four damping mechanisms, and the damping mechanism includes a fixed seat that is clamped and fixed with the corresponding gear fixing buckle and the fixing buckle. A guide protrusion is provided on one side of the fixed seat, and the guide protrusion is slidably connected with the guide groove provided on the surface of the slider. The guide protrusion and the guide groove are slidably matched to form a guide mechanism. Two compression springs located on both sides of the guide mechanism are also provided between the fixed seat and the slider, and the two ends of the compression spring are respectively socketed with the positioning pins provided on the fixed seat and the side of the slider.

[0011] As a preferred technical solution of the present invention, one end of the left gear fixing buckle and one end of the left fixing buckle of the two synchronous folding mechanisms located at the hinge end are engaged with the fixing seat fixedly installed on the left adhesive backing plate, the right gear fixing buckle and the right fixing buckle of the two synchronous folding mechanisms are engaged with the fixing seat fixedly installed on the right adhesive backing plate, and one end of the left gear fixing buckle and one end of the left fixing buckle of the remaining two synchronous folding mechanisms are engaged with the fixing plate fixedly installed on the left adhesive backing plate, and the right gear fixing buckle and the right fixing buckle of the two synchronous folding mechanisms are engaged with the fixing seat fixedly installed on the right adhesive backing plate.

[0012] As a preferred technical solution of the present invention, during the rotation of the hinge mechanism, the sliding displacement generated by the left finger track and the right finger track and the first adhesive plate is equal to the sliding displacement generated by the guide protrusion in the guide groove.

[0013] A mobile terminal comprises a 360° hinge as described in any one of the above items, and also comprises a first shell and a second shell respectively located on both sides of the hinge mechanism and forming a terminal shell, the backs of the first shell and the second shell are respectively fixedly mounted with a first back plate and a second back plate, and the first back plate and the second back plate are fixedly connected to corresponding sliders forming the connecting ends of the guide mechanism.

[0014] As a preferred technical solution of the present invention, the top of the first back panel and the second back panel are provided with a first support plate and a second support plate flush with the first adhesive backing plate and used for supporting and installing the flexible screen, and the first support plate and the second support plate are fixedly connected to the first shell and the second shell respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) By setting up multiple identical structures to form a synchronous folding mechanism, the structural composition of the internal action mechanism of the hinge is simplified, the complexity of the hinge is simplified, and the internal mutually meshing synchronous tooth buckle group is used to cooperate with the link buckle, so that multiple rotating shafts drive the outer steel bars to rotate synchronously, and the adhesive plate and the finger track are used to achieve smooth and stable support for the flexible screen during 0-360° rotation, thereby increasing the stability of the hinge mechanism. The synchronous gear buckle group formed by the meshing of the gear fixing buckle and the gear buckle can increase the smoothness of the hinge rotation and provide a better mechanical feedback, thereby improving the quality of the hinge and the mobile terminal. In addition, under the action of the synchronous gear buckle group, the multiple rotating shafts shorten the rotation stroke of the hinge input to 1 / 2 of the output rotation stroke, which is equivalent to shortening the actual input rotation stroke, thereby improving the user experience of the hinge;

[0017] 2) By setting the adhesive backing plate, the hinge always maintains a constant length of support for the screen during the 0-360° and 360-0° rotation of the hinge, and the sliding distance between the tooth opening of the finger guide rail and the tooth opening of the first adhesive backing plate is compensated by the slider of the damping mechanism to prevent the finger guide rail and the first adhesive backing plate from causing damage to the flexible screen. The elastic force of the compression spring in the damping mechanism generates reverse damping during the rotation of the hinge, and equal damping is generated on the left and right sides of the terminal, which provides a better experience. In addition, the existence of the damping effect enables the hinge to have a certain locking effect.

[0018] 3) The hinge has a reasonable structure and is applicable to a wide range of scenarios. When the screen is flipped to 0°, the screen can be bent to the back of the terminal to prevent the screen from being scratched. When the screen is flipped to 180°, the unfolded flexible screen can provide a 2 times larger screen experience. When the screen is flipped to 360°, a portable mobile display experience can be obtained. The R-angle display area of ​​the flexible screen can give people a waterfall screen experience.

[0019] 4) This type of 360° folding hinge has a simple structure, low manufacturing cost, and long service life, and can be better adapted to a variety of mobile terminals (mobile phones, laptops, tablets, etc.) or other terminals with folding display requirements, and has good adaptability.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figure 1-11The present invention provides a 360° hinge, including a hinge mechanism 1, the hinge mechanism 1 includes eight horizontally arranged outer steel bars 11, four synchronous folding mechanisms 1a are installed on the inner side of the eight outer steel bars 11 for realizing smooth synchronous rotation of the terminal shell by 0-360° and cooperating with the first adhesive backing plate 17 to provide constant length support for the flexible screen, and the synchronous folding mechanism 1a is provided with a synchronous tooth buckle group for the rotation cooperation of multiple rotating shafts thereof to ensure the smooth rotation of the hinge and provide mechanical feedback, and drive the corresponding damping mechanism 1b to rotate synchronously;

[0035] The damping mechanism 1b is provided with a guide mechanism for compensating the folded distance of the adhesive backing plate of the hinge mechanism 1 and providing hinge rotation damping when the hinge rotates, and the guide mechanism is provided with a connection end for connecting to the terminal housing;

[0036] The hinge mechanism 1 further comprises a left finger track 15 and a right finger track 16 which are located on both sides of the top of the synchronous folding mechanism 1a and cooperate with the damping mechanism 1b and the first adhesive plate 17 to lock the terminal housing when it is folded.

[0037] In this embodiment, the synchronous folding mechanism 1a includes two groups of shafts 1a1, two groups of shafts 1a2, two groups of shafts 3a3 and two groups of shafts 4a4, which form eight rotating shafts. Each group of shafts 1a1, shaft 2 1a2, shaft 3 1a3 and shaft 4 1a4 are symmetrically arranged and are respectively arranged relative to the eight outer steel bars 11. Both ends of shaft 1a1, shaft 2 1a2, shaft 3 1a3 and shaft 4 1a4 are sleeved with gear buckles 1a6 that mesh with each other and realize synchronous rotation. The eight rotating shafts are chain-connected by link buckles 1a5 sleeved in the middle thereof, located at The left fixed buckles 1a8 and the right fixed buckles 1a10 are respectively alternately sleeved between the link buckles 1a5 on the two shafts 1a1, and two left gear fixed buckles 1a7 meshingly connected with the two gear buckles 1a6 on the corresponding shafts 1a1 are arranged on both sides of the multiple left fixed buckles 1a8, and two right gear fixed buckles 1a9 meshingly connected with the two gear buckles 1a6 on the corresponding shafts 1a1 are arranged on both sides of the multiple right fixed buckles 1a10. The gear buckles 1a6 mesh with the left gear fixed buckle 1a7 and the right gear fixed buckle 1a9 to form a synchronous gear buckle group to ensure smooth rotation of the hinge.

[0038] Specifically, when the mobile terminal is folded 0-360°: by pulling the first shell 2 clockwise and pulling the second shell 3 counterclockwise, the force is applied to the left gear fixing buckle 1a7 and the left fixing buckle 1a8. Similarly, the left gear fixing buckle 1a7 and the left fixing buckle 1a8 will also drive the shaft 1a1 to rotate. Since the shaft 1a1, the shaft 2 1a2, the shaft 3 1a3 and the shaft 4 1a4 are connected by the gear buckle 1a6 and the link buckle 1a5, then under the action of the synchronous gear buckle group, the rotation stroke of the hinge input is shortened to 1 / 2 of the output rotation stroke. At this time, the right gear fixing buckle 1a9 and the right fixing buckle 1a10 are synchronously rotated counterclockwise, and then under the action of the synchronous folding mechanism 1a, the synchronous rotation of the terminal shell is realized;

[0039] When the mobile terminal is folded 360-0°: by turning the first housing 2 counterclockwise and the second housing 3 clockwise, the synchronous rotation of the terminal housing is also achieved under the action of the synchronous folding mechanism 1a.

[0040] Furthermore, support columns 12 for connecting the devices are sleeved between the relatively positioned rotating shafts in multiple adjacent synchronous folding mechanisms 1a, wherein the rotating shafts of the two synchronous folding mechanisms 1a located at both ends of the outer steel bar 11 are sleeved with the connecting shafts at the ends of the outer steel bar 11 through the sleeved support columns 12, so that when the rotating shafts of the multiple synchronous folding mechanisms 1a rotate, the relatively positioned rotating shafts can rotate synchronously, and at the same time drive the corresponding outer steel bars 11 to rotate synchronously around their respective axes.

[0041] In this embodiment, four damping mechanisms 1b are provided, and the damping mechanism 1b includes a fixed seat 1b1 which is clamped and fixed with the corresponding gear fixing buckle and the fixing buckle. A guide protrusion 1b11 is provided on one side of the fixed seat 1b1. The guide protrusion 1b11 is slidably connected with a guide groove 1b21 provided on the surface of the slider 1b2. The guide protrusion 1b11 and the guide groove 1b21 are slidably matched to form a guide mechanism. Two compression springs 1b3 located on both sides of the guide mechanism are also provided between the fixed seat 1b1 and the slider 1b2. The two ends of the compression spring 1b3 are respectively socketed with the positioning pins provided on the sides of the fixed seat 1b1 and the slider 1b2.

[0042] Specifically: When the mobile terminal rotates 0-360° and 360-0°, in order to ensure that the flexible screen always maintains constant length support during the rotation process, the slider 1b2 located inside the first shell 2 and the second shell 3 slides on the fixed seat 1b1 in each shell to compensate for the rotation of the adhesive backing plate. At the same time, the teeth of the left finger track 15 and the right finger track 16 can slide with the teeth of the first adhesive backing plate 17. The sliding between the teeth can absorb the ΔL generated by the hinge under the constant length constraint. The mathematical principle of this process can be found in Fig. 9 , 10, 11, where the hinge is at an angle of 0° ( Fig.10 As shown), L = 2L1 + L2 - 2ΔL, ΔL = BA; when the hinge is at an angle of 360° ( Fig.11 As shown), L = 2L1 + L2 + 2ΔL, ΔL = AC;

[0043] During the hinge rotation, the slider 1b2 slides on the fixed seat 1b1 to generate a displacement difference, compensating for the ΔL transmitted by the finger track sliding under the hinge constant length constraint. The elastic force of the compression spring 1b3 generates reverse damping during the hinge rotation, and the existence of this damping makes the hinge have a certain locking effect and locks the slider 1b2 at the same time.

[0044] In this embodiment, one end of the left gear fixing buckle 1a7 and one end of the left fixing buckle 1a8 of two synchronous folding mechanisms 1a located at the hinge end are engaged with the fixing seat 1b1 fixedly installed on the left adhesive backing plate 13, and the right gear fixing buckle 1a9 and the right fixing buckle 1a10 of the two synchronous folding mechanisms 1a are engaged with the fixing seat 1b1 fixedly installed on the right adhesive backing plate 14, and one end of the left gear fixing buckle 1a7 and one end of the left fixing buckle 1a8 of the remaining two synchronous folding mechanisms 1a are engaged with the fixing plate 19 fixedly installed on the left adhesive backing plate 13, and the right gear fixing buckle 1a9 and the right fixing buckle 1a10 of the two synchronous folding mechanisms 1a are engaged with the fixing seat 1b1 fixedly installed on the right adhesive backing plate 14. 10 is engaged with a fixing plate 19 fixedly mounted on the right adhesive backing plate 14, wherein one side of the left finger track 15 is engaged with one end of the left gear fixing buckle 1a7, one end of the left fixing buckle 1a8 and the corresponding fixing plate 19, wherein one side of the right finger track 16 is engaged with one end of the right gear fixing buckle 1a9, one end of the right fixing buckle 1a10 and the corresponding fixing plate 19, the teeth on the other side of the left finger track 15 and the teeth on the other side of the right finger track 16 are meshed with the teeth correspondingly arranged on both sides of the first adhesive backing plate 17, and a second adhesive backing plate 18 is also arranged at the bottom of the first adhesive backing plate 17 and is placed between the outer steel bar 11 and the synchronous folding mechanism 1a.

[0045] Specifically, when the mobile terminal performs 0-360° and 360-0° rotations, the rotating gear fixing buckle and the fixing buckle can drive the fixing seat 1b1 and the fixing plate 19 to rotate synchronously. Under the driving action of the fixing seat 1b1, the left adhesive bottom plate 13 and the right adhesive bottom plate 14 slide on the back plate, and the distance between the finger track and the adhesive plate is compensated.

[0046] Furthermore, during the rotation of the hinge mechanism 1, the sliding displacement generated by the left finger rail 15 and the right finger rail 16 and the first adhesive plate 17 is equal to the sliding displacement generated by the guide protrusion 1b11 in the guide groove 1b21, ensuring stable and smooth support for the flexible screen when the mobile terminal rotates within the range of 0-360°.

[0047] A mobile terminal, comprising a 360° hinge of any one of the above items, and also comprising a first shell 2 and a second shell 3 respectively located on both sides of a hinge mechanism 1 and forming a terminal shell, the backs of the first shell 2 and the second shell 3 are respectively fixedly mounted with a first back plate 21 and a second back plate 31, the first back plate 21 and the second back plate 31 are fixedly connected to the corresponding slider 1b2 forming the connecting end of the guide mechanism, so that the 360° hinge can be adapted to a better mobile terminal.

[0048] Furthermore, the top of the first back panel 21 and the second back panel 31 are provided with a first support plate 22 and a second support plate 32 which are flush with the first adhesive backing plate 17 and are used to support and install the flexible screen. The first support plate 22 and the second support plate 32 are fixedly connected to the first shell 2 and the second shell 3 respectively. The first back panel 21 and the second back panel 31 cooperate with the first adhesive backing plate 17 to stably support and install the flexible screen.
