Detailed Description

It is to be understood that various alternative constructions and implementations may be devised by those skilled in the art without departing from the spirit of the 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 limiting or restricting the technical aspects of the present disclosure in all or in part.

The directional terms upper, lower, left, right, front, rear, front, back, top, bottom and the like that are or may be mentioned in this specification are defined relative to the configurations shown in the drawings, and are relative concepts that may be changed accordingly depending on 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.

Referring to fig. 1, a perspective view of a multi-segment flexible spindle assembly according to an embodiment of the present disclosure is shown.

A multi-stage flexible shaft assembly 100 disposed between and connecting a first body and a second body of an electronic device such that the first body and the second body can rotate relative to each other, the multi-stage flexible shaft assembly 100 comprising:

a flexible stent 1 for connecting the first body and the second body;

at least three rotating shafts 2, which are sequentially arranged on the flexible support 1; and

a link 3 disposed at an end of the rotation shaft 2,

wherein the connecting rods 3 cooperate with each other and form a stroke limitation for the movement relative to each other.

It is understood that flexible means bendable or turnable, having a certain softness, flexibility. Here, for example, the displacement of the rotary shafts 2 on the flexible supports 1 relative to one another is supported by the assembly so that the rotation or bending effect is achieved overall, while the linkages 3, by interacting with one another, achieve a limitation of the bending angle, which can encompass both an angular limitation in the forward direction (for example, in the case of smart glasses, the direction in which the temple is folded inwards, i.e. the end of the temple remote from the frame is oriented closer to the frame; for example, in the case of a foldable mobile phone, the overall folding inwards, i.e. the display side-to-side direction of the inner screen) and an angular limitation in the reverse direction (for example, in the case of smart glasses, the direction in which the temple is folded outwards, i.e. the end of the temple remote from the frame is oriented farther from the frame; for example, in the case of a foldable mobile phone, the overall folding outwards, i.e. the display side-to-back direction of the inner screen).

The flexible stent 1 may be made of a flexible material, which may include, for example, tpu (thermoplastic polyurethanes), silicone, pom (polyformaldehyde), and the like.

In the multi-section flexible rotating shaft assembly 100 provided by the embodiment of the present disclosure, at least two bending nodes are formed by at least three rotating shafts 2, that is, at least two-section turning processes are formed. For example, in the smart glasses in the related art, when the temple is folded, the temple has only a 90-degree bend angle with respect to the smart glasses main body (frame), the turning radius is small, and the cable inside the smart glasses may be excessively bent. According to the multi-section flexible rotating shaft assembly 100 provided by the embodiment of the disclosure, under the condition of two bending nodes, two-section segmentation of a 90-degree rotating angle is realized, for example, each bending node bears a 45-degree turn, the radius of the rotating angle is increased, so that the turning amplitude is reduced in a multiple manner, the risk that an internal signal line is excessively bent is reduced in a multiple manner, and the risk that the whole intelligent glasses are abnormal in function due to the fact that the radius of the rotating angle of the rotating shaft is smaller when the glasses legs are closed and the internal cable is damaged after being rotated for multiple times is avoided. Meanwhile, the risk of bending damage of the flexible circuit board of the intelligent glasses is avoided, and the service life of the intelligent glasses is prolonged. Under the condition that the number of the rotating shafts is more, the effect of sharing the turning angles of more sections can be realized, and therefore more precise adjustment of the turning angles can be provided. In a similar way, the multi-section flexible rotating shaft assembly 100 provided by the embodiment of the present disclosure can increase the radius of the corner of the foldable mobile phone around the screen, and the turning range is reduced, so that even if the foldable mobile phone is repeatedly folded for use, the crease will not become obvious, and the risk of screen breaking and cracking which may exist is avoided or greatly reduced. The bending strength of the components in the screen and the CPI film or UTG glass on the screen is also reduced. In addition, more sections of turning angle allocation can be provided by adjusting the number of the rotating shafts, and the precise control of the turning angle is realized.

The multi-section flexible rotating shaft assembly 100 provided by the embodiment of the present disclosure can be applied to various foldable electronic devices, for example, such electronic devices may include at least one set of a first body and a second body that need to be relatively rotated (folded), and the multi-section flexible rotating shaft assembly 100 connects the first body and the second body so that the first body and the second body can be relatively rotated.

It should also be understood that the foldable electronic device is a broad concept, which includes not only a case where the main body of the entire device is foldable (e.g., foldable cellular phone), but also a case where parts of the device are foldable (e.g., temple of smart glasses).

In some embodiments, the connecting rod 3 has a connecting rod opening 34 and is sleeved on the end of the rotating shaft 2 through the connecting rod opening 34, the rotating shaft 2 comprises an abutting part 21, and the connecting rod 3 abuts against the abutting part 21.

In some embodiments, the shaft 2 can be designed as a cylinder, and the abutment 21 can be designed as a radially widened flange on the outer circumference of the cylinder. It should be understood that the cylindrical shapes described above are merely illustrative and that other possible configurations may be suitable.

Referring to fig. 2 to 5, there are shown a perspective view, a side view, and an operation state diagram of the multi-sectional flexible rotary shaft assembly at the forward and reverse limit positions, respectively, according to some embodiments of the present disclosure.

In some embodiments, the connecting rod 3 includes a first sub-connecting piece 31 and a second sub-connecting piece 33 connected to each other, and the first sub-connecting piece 31 and the second sub-connecting piece 33 are respectively sleeved on the ends of two adjacent rotating shafts 2. The design mode ensures the structural stability and the rotational stability of the adjacent rotating shafts. More, e.g. 4 or 5, shafts 2 may be designed to achieve more angular sharing of the turning angle to fit the shape of the connecting rod 3, fig. 4 illustrates 5 shafts 2 as an example.

In some embodiments, the first sub-coupling piece 31 and the second sub-coupling piece 33 are configured in a rectangular basis, and the longitudinal side is modified into a circular arc-shaped plectrum shape, and the circular arc radian of the link opening 34 may be the same as the aforementioned circular arc radian so as to be adapted to the turning action of the assembly.

In some embodiments, the first and second

sub-connection pieces

31 and 33 may have a height difference in the thickness direction, i.e., a staggered arrangement. This design of the step facilitates that the individual links 3 can be mounted on the end of the same shaft 2 in a nested manner, for example the second sub-web 33 of the opposite left link and the first sub-web 31 of the opposite right link of each two adjacent links are arranged in a stack in the manner described above, and the limitation of the amplitude of the turning movement is achieved by the interaction of the two sub-webs. This stacking design also has the technical effect of saving space, keeping the entire assembly compact, in particular the width of the entire assembly unchanged by the number of shafts 2 and connecting rods 3.

In some embodiments, the connecting rod 3 further comprises a transition 32 between the first and second

sub-connecting pieces

31, 33, the transition 32 bridging the height difference in the thickness direction of the first and second

sub-connecting pieces

31, 33.

The above description illustrates by way of example that the first sub-coupling piece 31 is configured to be higher in the thickness direction than the second sub-coupling piece 33, but it should be understood that a link of opposite design may be employed on the end of the opposite side of the rotation axis to achieve the same technical effect, i.e. the first sub-coupling piece 31 is configured to be lower in the thickness direction than the second sub-coupling piece 33.

In some exemplary embodiments of the disclosure, the second partial connection piece 33 comprises, on its first end side facing the first partial connection piece 31, a first direction stop 331 and a second direction stop 332 which are configured at a distance from one another, and on its second end side facing away from the first partial connection piece 31, a mating projection 333, which mating projection 333 can be stopped against the first direction stop 331 and the second direction stop 332 of an adjacent second partial connection piece 33.

It should be understood that the first direction and the second direction are two turning directions different from each other, for example, the first direction may be a forward direction and the second direction may be a reverse direction. With the above-described technical solution, the movement of the engaging protrusion 333 is limited between the first direction stopper 331 and the second direction stopper 332, and the turning amplitude limitation in both directions is achieved.

It will also be appreciated that the positions of said first and second direction stops 331, 332 determine the limit points for forward and reverse, and the spacing between said first and second direction stops 331, 332 determines the magnitude of the turn.

In some embodiments, the first direction stop 331 is located midway on the first end side, the mating projection 333 is located midway on the second end side, and the second direction stop 332 is located at a corner on the first end side. This design is clearly shown in fig. 4, and both stops are also in the form of cams, so that the manufacture is easy and cost-effective, while at the same time the desired stop action is achieved.

Although not explicitly described in the present disclosure, the arrangement positions of the first direction stop 331, the second direction stop 332 and the matching protrusion 333, and the number of the rotating shafts and the connecting rods can be adjusted according to actual needs (for example, how many degrees each rotating node is required to rotate, how large the rotating angle of the whole assembly is required to be, and which limit position the positive and negative maximum rotating angles are expected to be) to adapt to different use conditions.

For example, for the application to smart glasses, the maximum bending angle in the forward direction may be designed to be 90 degrees, the maximum rotation amplitude of 30 degrees is realized by a single rotation node, and the maximum bending angle in the reverse direction is set to be 0 degree, i.e. the temple is not allowed to rotate outwards in accordance with the practical application.

As exemplarily shown in fig. 2 and 3, in some embodiments, the connecting rod 3 includes two first sub-connecting pieces 31 and two second sub-connecting pieces 33, wherein the first direction stop 331 and the second direction stop 332 are disposed between the two first sub-connecting pieces 31, and the mating protrusion 333 is disposed on one of the second sub-connecting pieces 33.

According to the above-described embodiment, the connecting rod 3 is constructed in a two-layer structure. The benefits of this double-layer structure include protection of the first and second direction stops 331, 332 from the environment, greater structural stability and support strength, and direct application on the opposite end sides of the shaft, with good versatility. During use, one of the second sub-connection pieces 33 comprising the mating projection 333 is located between the two first sub-connection pieces 31, so that the mating projection 333 can also be protected due to this double layer design. It should be understood that more multi-layer structural designs are possible, and the specific design can be extended with reference to the above two-layer structure.

In some embodiments, the connecting rod 3 further comprises a support portion 35, the support portion 35 being configured at a bottom side of the connecting rod 3 and abutting against the first sub-connecting piece 31 which is located relatively below, so as to enhance the support strength of the entire connecting rod 3.

In some embodiments, the support portion 35 is also aligned with the second sub-connecting piece 33 which is located relatively below, so as not to increase the thickness of the entire connecting rod 3 while enhancing the support strength.

Although the above description illustrates the reinforcement by way of example, this is not limiting and other common reinforcement means such as ribs, brackets, channels, etc. may be suitable.

In some embodiments of the present disclosure, the hinge 2 includes a hollow structure 22 for passing cables of electronic equipment, such as signal lines, power lines, data lines, connecting lines, and the like.

In some embodiments of the present disclosure, the flexible mount 1 further includes a limiting groove for guiding a cable of the electronic device, such as a signal line, a power line, a data line, a connecting line, and the like.

Hollow out construction and/or spacing groove can provide accommodation space for electronic equipment's inside cable, have avoided inside cable to expose, are convenient for lay wire.

For example, the retaining groove may be configured as a plurality of grooves spaced apart from each other at equal intervals, and configured on the upper surface of the flexible support 1, and the design form of the grooves additionally provides a retaining function for the internal cables of the electronic device, so as to prevent the cables from shifting or even knotting during the folding process. The shape, the number and the size of the limiting groove can be adjusted according to the specification of the internal cable.

Referring to fig. 6, the multi-section flexible rotating shaft assembly 100 provided by the embodiment of the present disclosure may further include a torsion adjusting screw 4, wherein the rotating shaft 2 includes a rotating shaft hole, and the torsion adjusting screw 4 is inserted into the rotating shaft hole and abuts against the connecting rod 3. Since the link 3 also abuts against the abutting portion 21, the torsion adjusting screw 4 applies a tightening force to the link 3. By adjusting, for example screwing, the torsion adjusting screw 4, so that it is displaced in the longitudinal direction of the spindle 2 within the spindle 2, the tightening force on the connecting rod 3 is correspondingly changed, whereby a tightening adjustment is achieved.

It will be appreciated that the degree of tightness determines the ease of turning of the entire assembly and temple and the degree of stability of the structure maintained after the rotation is complete. Therefore, for example, the screws can be loosened to perform bending when the bending angle of the temple needs to be adjusted, and the screws can be tightened to perform sizing when the bending angle is adjusted; the screw can be screwed to a certain amount, so that a certain structural shaping degree can be ensured, and the resistance when the glasses legs are required to be bent is not too large. Optionally, the spindle opening is configured as a threaded hole to better interact with the torque adjustment screw 4.

Alternatively, the torsion adjusting screws 4 may be assigned only to the rotary shafts 2 belonging to the rotary nodes, while the rotary shafts at both ends may not be assigned torsion adjusting screws.

In some embodiments of the present disclosure, in the case that the multi-section flexible rotating shaft assembly 100 is not rotated, the cross section of the flexible support 1 is rectangular, and a connecting position is included at a position where the first body and the second body are connected.

The implementation structure of the connection position can be adjusted according to the type of the electronic device to which the multi-section flexible rotating shaft assembly 100 is applied. For example, the connection sites include fixing holes 11 at the edges (e.g., four corner positions) of the flexible stent 1. Through the fixing hole 11, different main bodies of the electronic equipment can be fixedly connected with the multi-section flexible rotating shaft assembly. E.g. to the temple, frame of smart glasses, housing of different display screens of a foldable mobile phone.

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.

Through the technical scheme, the whole assembly is fixed to different main bodies of the electronic equipment, such as the glasses legs and the glasses frames of the intelligent glasses, through the fixing holes 11.

Although the above description illustrates the implementation of the connection sites 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 position of the connection sites may be adjusted according to the corresponding site of the electronic device to be mounted.

That is, the first body and the second body according to the present disclosure do not necessarily mean that the two bodies belong to two different parts of the electronic device, but may belong to two parts of the same part, for example, two parts of a temple of smart glasses, so that the multi-section flexible hinge assembly provided by the embodiment of the present disclosure may be fixed to any temple of the smart glasses.

In order to protect the multi-sectional flexible shaft assembly from the external environment, the multi-sectional flexible shaft assembly 100 may include a housing 5.

For example, the housing 5 may be made of flexible material such as POM, TPU or silicone, which has good durability and good aesthetics without affecting the rotational effect of the assembly.

Referring to fig. 8-11, schematic diagrams of left temple closures of smart glasses according to an embodiment of the present disclosure for 30 °, 60 °, and 90 °, respectively, are shown.

It should be understood that the above angles are only exemplary, and may be modified according to actual needs, for example, the turning angles that can be achieved by the respective turning nodes and the whole assembly may be changed by changing the number of the rotating shafts and the connecting rods, and designing the arrangement positions of the first direction stopper, the second direction stopper and the mating protrusion.
