Detailed Description

It is easily understood that according to the technical scheme of the present disclosure, a plurality of structures and implementation modes which can be replaced mutually can be proposed by a person with ordinary skill in the art without changing the essential spirit of the present disclosure. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present disclosure, and should not be construed as being all of the present disclosure or limiting or restricting the technical aspects of the present disclosure.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

With the development of computer technology, near-eye display technology or wearable devices, various foldable or wearable devices, products (e.g., smart wearable electronic products based on a novel 3D human-computer interaction concept) including smart electronic products have come into the market and gradually enter the consumer market. Smart glasses (Smart Glass) is one of wearable Smart products, including but not limited to XR (Extended Reality) product forms such as AR (Augmented Reality), MR (Mixed Reality), VR (Virtual Reality), CR (computerized Reality), etc., and is getting more and more attention from a Virtual world inputted through a limited sensor to a fully immersive Virtual world. The augmented reality includes Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), and other forms. In other words, XR is a generic term, and is divided into multiple layers, including AR, VR, and MR.

Similar to smart glasses, foldable devices, such as foldable mobile phones, have been developed explosively over the past two years, and various foldable mobile phone forms, such as half-open, left-right, up-down, inner-folding, and outer-folding, have appeared. No matter the design of fold-in or fold-out, there is the risk that screen breakage, screen cracking or fold marks are obvious caused by excessive bending for the mobile phone screen. The components within the screen and the CPI film or UTG glass on the screen also run the risk of bending damage.

Referring to fig. 1 and 2, there are shown an overall structural schematic view of a rotating shaft according to an embodiment of the present disclosure, and an exploded schematic view of a rotating shaft according to an embodiment of the present disclosure.

A hinge 1 according to an embodiment of the present disclosure can be disposed between a first body 21 and a second body 22 of a foldable device 2 and connect the first body 21 and the second body 22 so that the first body 21 and the second body 22 can rotate relatively, wherein the hinge 1 includes:

a rotation shaft base 11 including a fitting shaft 111;

a spring 12 having one end thereof disposed on the rotation shaft base 11;

a stopper 13 provided at the other end of the spring 12, the stopper 13 including a first pressing portion 131; and

a rotating arm 14 disposed above the stopper 13 and capable of performing first rotation and second rotation in different directions about the fitting shaft 111, the rotating arm 14 including a second pressing portion 141,

wherein the content of the first and second substances,

the spring 12, the stopper 13, and the rotating arm 14 are fitted around the fitting shaft 111, and during the first rotation, the first pressing portion 131 and the second pressing portion 141 can abut against each other and cause the stopper 13 to move toward the rotation shaft base 11 and press the spring 12.

It should be understood that reference herein to a foldable device is a broad concept and includes not only the case where the body of the entire device is foldable (e.g., foldable cell phones), but also the case where the components of the device are foldable (e.g., the glasses include the temple of smart glasses). The rotating shaft 1 provided by the embodiment of the present disclosure can be applied to various foldable devices, for example, such devices may include at least one set of a first body and a second body that need to be relatively rotated (folded), and the rotating shaft 1 connects the first body and the second body so that the first body and the second body can be relatively rotated. Furthermore, the designations of the first body 21 and the second body 22 are only for the purpose of distinction and do not necessarily mean that the two bodies must belong to two different components, which, depending on the actual situation, may also be two parts of one and the same component. The phrase "the rotating arm 14 is disposed on the stopper 13" means that the rotating arm 14 may be disposed above or on the stopper 13. The first rotation and the second rotation (or the rotation in the first direction and the rotation in the second direction) may specifically be a counter-clockwise rotation and a clockwise rotation (from a top-down perspective in fig. 1), respectively.

When the first pressing portion 131 and the second pressing portion 141 abut against each other and move the stopper 13 toward the spindle base 11 and press the spring 12, it will be appreciated that the spring 12 will generate a reaction force to the stopper 13, which will generate a resistance to the rotation of the rotating arm in the first direction, and in the absence of a force source for such first rotation (for example, when the smart glasses are already in place on the head of the user), such reaction force can cause the rotating arm 14 to rotate in the second direction via the first pressing portion 131 and the second pressing portion 141, thereby generating and maintaining a clamping force to the head of the user, so that the foldable device, such as the glasses, always abuts against the head of the user and does not fall off the head. Therefore, through above-mentioned technical scheme for but folding equipment can adapt extensive user crowd to it is firm to wear, promotes the user and wears experience, and to same glasses, the user of various head types can both obtain the clamp force.

In case the foldable device is an electronic device such as a foldable cell phone, a tablet computer, a notebook computer, the hinge 1 may also be used to prevent the screen of the electronic device from being rotated excessively, for example to prevent the display screen from being rotated in the opposite folding direction, or resistance is generated in the above-described manner in the case where such reverse rotation occurs, and the screen can be rotated back to the critical position in time in the case where the source of the application of force disappears (i.e., the position where the first and second pressing portions just collide without pressing force, such as a flat state, i.e., the left portion of the rotating shaft base body 11 with the fitting hole and the right portion of the rotating arm 14 with the fitting hole are in the same plane), therefore, the risks of screen cracking, screen breaking and remarkable folding caused by excessive bending of the screen of the electronic equipment and damage of components (such as components in the screen, films on the screen and glass) related to the screen can be avoided.

It will also be appreciated that the position of said first pressing portion 131 and said second pressing portion 141 determines when (i.e. to what extent the first rotation of the rotating arm has taken place) such a return or clamping force starts to take effect, i.e. determines a critical position which has not yet been taken effect. Therefore, the positions of the rotating arm and the rotating shaft base can be designed according to actual conditions, for example, as shown in fig. 1, the critical position is a state that the rotating arm and the rotating shaft base (or the part on the left side of the rotating arm) are spread out by 180 degrees, and the method can be well applied to application scenes of glasses or electronic equipment. Of course, the critical position may be changed to other angular states. In addition, the first rotation "period" does not require that the abutment of the two pressing portions is triggered during the whole course of the first rotation, but only a part of the first rotation (usually the last part of the first rotation), that is, the first rotation may have a "idle rotation period" first (depending on the initial state of the rotation shaft), and then the abutment of the pressing portions is triggered at the end after the rotation arm has rotated in the first direction for a certain time or a certain stroke. The second rotation period described below can also be interpreted similarly.

It can also be seen from the figure that the stop block 13 further comprises a first stop portion 132, and the rotating arm 14 further comprises a second stop portion 142, and during the second rotation, the first stop portion 132 and the second stop portion 142 can abut against each other and prevent further rotation of the rotating arm 14. That is, the two stops set the limit positions for the second rotation of the swivel arm. For example, in the case where the rotary shaft is applied to eyeglasses, the temples can be prevented from turning excessively to collide with the frame. In the case where the hinge is applied to an electronic apparatus, it is also possible to prevent the screens from turning excessively so as to collide with each other.

Similarly, the positions of the first stopping portion 132 and the second stopping portion 142 determine the design of the above-mentioned limit positions, and the positions thereof can be designed or adjusted according to actual conditions, for example, as shown in fig. 3, the rotating arm is turned inward by 90 degrees to be the limit position. Thus, the rotation between the stopper and the pressing portion can be regarded as a lost motion period. It will also be appreciated that the number of stops and extrusions may also be modified as required. Therefore, the rotating shaft 1 provides an angle limitation of the inward turning or forward direction (for example, for intelligent glasses, the inward folding direction of the glasses legs, namely the direction from one end of the glasses legs far away from the glasses frame to the side close to the glasses frame; for foldable mobile phones, the whole device is folded inward, namely the display side of the inner screen faces to the other direction).

Regarding the shapes of the stoppers and the pressing portions, in some embodiments of the present disclosure, the first stopper 132 and the second stopper 142 each include a vertical surface, and the first pressing portion 131 and the second pressing portion 141 each include a slope. These embodiments enable the required stop or pressing function to be achieved in a good manner, and are simple and inexpensive to produce. The requirements for different extreme and critical positions can be met by using stop blocks (or swivel arms) with different positions, numbers or shapes of stops or presses. In addition, it should be appreciated that the inclined surface is inclined in a direction facing the rotating arm as shown in fig. 1, so as to achieve the aforementioned technical effects.

In some embodiments of the present disclosure, a length (height in the drawing) of an abutting portion between the first pressing portion 131 and the second pressing portion 141 in the moving direction of the stopper 13 is larger than a distance between the stopper 13 and the spindle base body 11 when the first pressing portion 131 and the second pressing portion 141 are not yet abutted against each other. That is, during the process of abutting the pressing portion and moving the stopper toward the rotation shaft base body, due to the above-mentioned dimensional relationship design, the stopper 13 eventually hits against the rotation shaft base body 11 (e.g., the upper surface thereof) during the moving process, thereby preventing the rotation arm 14 from continuing to rotate in the first direction, and achieving the stopper effect for the first rotation of the rotation arm 14. The design of the limit position can effectively prevent the rotating shaft and the applied foldable equipment from being bent excessively due to the fact that the force application source does not disappear after the rotating shaft and the applied foldable equipment exceed the critical position to a certain extent, and serious damage or deformation can be avoided. The present shaft 1 thus provides angular limitation in an eversion, or reverse, direction (e.g. for smart glasses the temple-folding direction, i.e. the direction from the end of the temple away from the frame towards the frame; e.g. for foldable mobile phones the whole is folded outwards, i.e. the display side of the inner screen is back-to-back).

Such an extreme position is for example visible from fig. 4, which shows a schematic view of a state of a spindle according to an embodiment of the disclosure when the rotor arms are turned 15 ° outwards, i.e. the extreme position corresponds to a 15 ° eversion. It should be understood that the angle of the limit position can be adjusted by designing the distance between the limit block and the rotating shaft base body or the position of the first and second pressing portions, and it is also possible to change the angle to 0 degree.

As can also be seen from the figure, the rotating shaft 1 is configured as a symmetrical structure and includes two assembling shafts 111, two springs 12, two stoppers 13 and two rotating arms 14, which are respectively disposed on two sides of a symmetrical plane of the rotating shaft base body 11 configured as a symmetrical structure. The figure illustrates a top-bottom symmetrical structure. The advantage of symmetrical structure lies in can realizing the power balance, can be more comprehensive, balanced, stably to the first main part of connecting, the second main part application of force, improved their life to rebound speed can be higher, the clamp force also can be higher, more durable and more balanced. In addition, the symmetrical structures can be regarded as a complement or redundancy among each other, so that the force exerted by a single component is low or the force application time is short, the service life of related components (such as the spring, the first pressing part and the second pressing part) is prolonged, and the function of the whole rotating shaft can be maintained by one component when the other component fails.

In order to assemble and fix the components of the rotating shaft 1, the rotating shaft 1 further comprises a fastening piece 15, and the fastening piece 15 is arranged on the rotating arm 14 and sleeved on the assembling shaft 111. The fastening member 15 illustratively includes a snap spring or a nut so that sufficient fixing and assembling effects can be achieved with a relatively simple structure and cost, and replacement can be performed at a proper time. The fastening member 15 makes the whole spindle 1 compact and does not come out when in use (especially the rotating arm which needs to be stressed). In the case of the fastening element 15 being configured as a nut, the mounting shaft 111 can, for example, be designed with an external thread in order to cooperate with the nut. The threaded fastening connection is a detachable fixed connection which is widely used and has the advantages of simple structure, reliable connection, convenient assembly and disassembly and the like. Although the above description illustrates the fixing method by way of example, this is not restrictive, and other common fixing methods, such as snap, magnetic attraction, etc., may also be applicable.

As can be well seen from fig. 2, the stopper 13 includes a first protruding portion 133, the first stopping portion 132 and the first pressing portion 131 are both disposed on the first protruding portion 133, and the rotating arm 14 includes a second protruding portion 144, and the second stopping portion 142 and the second pressing portion 141 are both disposed on the second protruding portion 144. Therefore, the dual functions of stopping and extruding are realized simultaneously through the arrangement of the convex parts, the manufacturing and design cost and the occupied space are saved, and the use efficiency is improved. Each projection can be provided in two, respectively, which are arranged opposite one another by 180 degrees in order to achieve a uniform, shared and stable stop and pressing effect. Specifically, one side of each protruding part is provided with a stopping part, and the other side of each protruding part is provided with a squeezing part.

As to the specific structure of each part of the rotating shaft 1, as can be clearly seen from fig. 2, the limiting block 13 includes a circular disc 134 for bearing the first stopping portion 132 and the first pressing portion 131 and abutting against the other end of the spring 12, the rotating shaft base 11 includes a cylinder 113 having an accommodating space therein, and the assembling shaft 111 and the spring 12 extend outwards from inside the cylinder 113. The entire spindle 1 is thus compact, the installation space of the spindle base body 11 is utilized to its full extent and its function as an installation base is maintained. It can also be seen that the spindle base 11 includes a first fitting hole 112 for fitting to the first body 21, and the rotary arm 14 includes a second fitting hole 143 for fitting to the second body 22. The rotating shaft base 11 is exemplarily divided into a left part, a right part and a transition part, wherein the transition part connects the left part and the right part, the right part is a structural combination of the cylinder 113 and the assembling shaft 111, and the left part is a cube with a rectangular rounded cross section and provided with an assembling hole. The swivel arm 14 may be divided into a left part and a right part, wherein the left part comprises said second boss 144 and is also carried by the disc. The limiting blocks and the rotating arms are provided with holes in the middle of the circular discs so as to be assembled with the assembling shaft 111. The right part of the swivel arm 14 comprises a connecting rod section as a transition section and a cube, which is likewise rectangular with rounded corners in cross section and which is provided with a fitting hole. The location, shape, number, etc. of the respective fitting holes can be adjusted according to the structure or type of the foldable device to be applied. Through this pilot hole, can be with the different main parts and the pivot fixed connection of equipment. E.g. to the temple, frame of smart glasses, housing of different display screens of a foldable mobile phone. The whole rotating shaft 1 is simple in structure and low in manufacturing and assembling cost, the technical effects can be achieved, and the rotating shaft, the main body and parts of the rotating shaft are easy to disassemble, assemble and maintain.

It should be noted that the "rectangle" herein is not required to be strictly and mathematically rectangular, but rather to exhibit a substantially rectangular shape, thereby allowing corresponding modifications to be locally designed, such as chamfers, rounds, recesses, protrusions, etc., which fall within the scope of the present disclosure. Although the above description illustrates the implementation of the mounting holes by way of example, this is not intended to be limiting and other structural implementations, such as adhesive, snap-fit, welded connections, etc., may also be suitable. Likewise, the size, shape, number and arrangement of the corresponding connecting means can be adjusted according to the corresponding portion of the foldable device to be installed.

In some embodiments of the present disclosure, the rotating shaft base 11, the spring 12, the stopper 13, and the rotating arm 14 are all made of metal, so that the rotating shaft 1 has high strength and the service life of the rotating shaft 1 is prolonged. It should be understood that the fastener 15 may also be made of metal.

In the assembled state of the rotating shaft 1, the spring 12 is already in a compressed state when the first pressing portion 131 and the second pressing portion 141 are not yet abutted against each other. That is, the spring 12 always has a reaction force against the stopper 13, so that the rotating arm 14 can be ensured not to be in an eversion position (i.e., a position rotated from the critical position in the first direction) exceeding the critical position but only in the critical position or an eversion position (i.e., a position rotated from the critical position in the second direction) relative to the critical position, thereby ensuring that the rotating shaft 1 and the foldable device 2 can be in a folding or critical state in a non-use state, saving the occupied space, being easy to store and prolonging the service life of related parts.

Referring to fig. 5 and 6, a simplified overall view of AR glasses according to an embodiment of the present disclosure and a schematic view of connection between a rotating shaft and a frame and a temple according to an embodiment of the present disclosure are shown.

The foldable device 2 comprises a first body 21 and a second body 22, and further comprises any one of the rotating shafts 1, wherein the rotating shaft 1 is arranged between the first body 21 and the second body 22 and connects the first body 21 and the second body 22, so that the first body 21 and the second body 22 can rotate relatively. Thus, the foregoing technical effects are imparted to the foldable device 2 through the rotating shaft 1, and are not described in detail herein. The connection mode of the rotating shaft and each main body can be realized by the fixation of the first assembling hole and the second assembling hole which are matched with screws.

As previously mentioned, the two bodies may be separate members or may be two different portions of the same member. For example, the foldable device 2 is eyeglasses, the first body 21 includes one of a temple and a frame of the eyeglasses, and the second body 22 includes the other of the temple and the frame of the eyeglasses; or said first body 21 and said second body 22 comprise two parts of said temple, i.e. the present rotation axis can be used for the relative rotation of the temple itself. It will be appreciated that a plurality of spindles 1 may be provided in a single foldable device 2, such as glasses or electronic devices, for example a pair of spindles 1 for a pair of glasses, one for each temple, to enhance the aforementioned technical effect and to provide a more balanced springback or clamping force. In addition, the glasses comprise smart glasses, and particularly can be smart glasses such as AR and VR. Although binocular smart glasses are illustrated, it should be understood that monocular smart glasses may also be applicable to the hinge 1 provided by the embodiments of the present disclosure. From this, under the condition of the mirror leg of AR glasses is applied to in the pivot that this disclosure provided, can drive the outside upset in-process of rotor arm at the mirror leg of AR glasses and produce elasticity after exceeding certain angle, mirror leg when this kind of antiport's elasticity makes the user wear produces the clamp force to user's head both sides to can the more user head types of adaptation, improve user experience.

In some embodiments of the present disclosure, the foldable device 2 is an electronic device including a foldable mobile phone, a foldable tablet computer, or a foldable notebook computer, and the hinge 1 may function as a separate hinge or an auxiliary hinge (to prevent excessive bending). Specifically, the electronic device includes a display module, a first display panel of the display module is located in the first main body 21, and a second display panel of the display module is located in the second main body 22. With this structure, the rotation shaft 1 is fixed to the rear cases (i.e., the cases away from the display panel) of the first and

second bodies

21 and 22, respectively. For example, the electronic device may be a foldable dual-screen mobile phone, which includes two separate and discontinuous display panels forming a display module, the connection portion between the two display panels adopts the hinge provided in any of the above embodiments, and extends along the longitudinal direction of the display panels, and the left side of the hinge base and the right side of the rotating arm (i.e., the portions respectively including the assembly holes) extend along the transverse direction of the display panels.

In some embodiments of the present disclosure, the electronic device includes a flexible display screen, a first non-bending portion of the flexible display screen is located in the first main body 21, a second non-bending portion of the flexible display screen is located in the second main body 22, the bending portion of the flexible display screen corresponds to the rotating shaft 1, and in the relative rotation process of the first main body 21 and the second main body 22, the bending portion deforms. Under the structure, the rotating shaft is respectively fixed with the rear shells of the first main body and the second main body (namely, the shell far away from the display panel direction), and is covered by the display panel of the bending part. The display module that this kind of electronic equipment includes is a complete, continuous display panel, and display panel includes both sides as the main display area's the portion of bending of non-bending and the portion of bending that is located between the portion of bending of non-, and this portion of bending covers the pivot. The first main body and the second main body can be arranged up and down symmetrically or asymmetrically relative to the bending part, and can also be arranged left and right symmetrically or asymmetrically relative to the bending part.

The hinge 1 can also be mounted to the foldable phone in the manner described above, specifically to the housing of the foldable phone, and can achieve corresponding features and technical effects.

In some embodiments of the present disclosure, the hinge 1 is parallel to a short side of the foldable cellular phone and is disposed in a central region with respect to a long side thereof in a state where the cellular phone is unfolded, thereby giving the foldable cellular phone a function of folding up and down. In other embodiments, the hinge 1 is parallel to a long side of the foldable cellular phone and is disposed in a central region with respect to a short side thereof in a state where the cellular phone is unfolded, thereby giving the foldable cellular phone a function of folding right and left. Although the above description has illustrated the way of folding the split screen by way of example, this is not limitative, and other ways of folding, such as the arrangement position, angle change, etc. of the present hinge with respect to the mobile phone screen, are also applicable.

Finally, the working principle of the rotating shaft and the application effect of the rotating shaft when the rotating shaft is applied to foldable equipment (taking AR glasses as an example) are comprehensively and briefly described.

During operation, pivot base member 11 is motionless, and at the rotor arm 14 simultaneously around the 90 degrees in-process of the inside upset of the assembly axle 111 of pivot base member 11, rotor arm 14 and stopper 13 do not have the extrusion, and the rotation process is smooth and easy, and when turning to 90 degrees (as in fig. 3), backstop portion second backstop portion 142 of rotor arm 14 and first backstop portion 132 of stopper 13 bump against each other, and stopper 13 hinders rotor arm 14, reaches the spacing effect of inside upset.

During the process that the rotating arm 14 is simultaneously turned outwards around the assembling shaft 111 of the rotating shaft base body 11, the second pressing portion 141 of the rotating arm 14 and the first pressing portion 131 of the limiting block 13 are pressed against each other, so that the limiting block 13 is pressed to move towards a neutral plane (i.e. towards the rotating shaft base body 11; in the case that the rotating shaft 1 is of a symmetrical structure, the neutral plane can also be understood as a symmetrical plane of the rotating shaft 1, such as a horizontal symmetrical plane), and the pressure of the spring 12 is increased, so that an elastic force is generated to prevent the limiting block 13 from moving towards the neutral plane, and the rotating arm 14 is indirectly prevented from rotating, and an elastic force of reverse rotation is generated.

When the rotating arm 14 is turned outwards by 15 degrees around the assembling shaft 111 of the rotating shaft base body 11 (as shown in fig. 4), the limiting block 13 moves to the neutral plane for a certain distance and then collides with the plane of the cylinder 113 of the rotating shaft base body 11, and the rotating arm cannot move continuously, so that the rotating arm 14 cannot turn continuously, and the effect of limiting the turning outwards is achieved.

The rotating shaft 1 is designed into the AR glasses temple (as shown in figure 5), and the AR glasses temple is smoothly folded inwards by 90 degrees when being stored. When the user wears AR glasses, the legs of the user are spread outwards on the two sides of the head, and the legs of the user are subjected to the elastic force of the rotating arm 14 in the rotating shaft 1 in the process of outwards turning, so that the clamping force of the left and right legs on products on the two sides of the head of the user is firm in wearing, and the experience feeling is greatly improved.

It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which would occur to persons skilled in the art upon consideration of this disclosure, are intended to be within the scope of the legal protection afforded this disclosure.
