It is understood that, in the case that the circuit trace 70 of the control system can be disposed between the first magnetic assembly 53 and the first pivoting body 51, the first magnetic assembly 53 can also be disposed on the first pivoting body 51.

The first magnetic assembly 53 may include a first mounting plate 531 provided on the first rotating part 52 and a first magnetic member 532 provided on the first mounting plate 531.

The first mounting plate 531 may enable the first magnetic member 532 to be mounted on the first rotating portion 52, and may also enhance the stability of the first rotating portion 52, such as the first engaging lug 521 and the second engaging lug 522.

The first magnetic member 532 is disposed on a surface of the first mounting plate 531 on a side away from the rotation axis to generate a magnetic force with the second hinge member 60. The first magnetic member 532 may be fixed on the first mounting plate 531 by a snap structure, a plug structure, an adhesive method, a welding method, or the like.

The surface of the first magnetic member 532 away from the rotation axis may be a curved surface, and in some embodiments, the cross section of the curved surface in the radial direction of the rotation axis is a circular arc around the rotation axis to better match with the second pivot member 60.

In an embodiment, the first magnetic member 532 may be directly fixed to the first pivot body 51 and/or the first rotating portion 52 when the first mounting plate 531 is omitted.

It will be appreciated that in some embodiments, the first magnetic member 532 may be disposed on a surface of the first mounting plate 531 on a side thereof adjacent to the spindle. A side surface of the first magnetic member 532 near the rotation axis may be a curved surface.

The second pivot member 60 may be made of a rigid material. The second pivot 60 is mounted to legs such as first leg 301 and second leg 302. In some embodiments, the second pivot element 60 can be installed in the space of the legs, such as the first leg 301 and the second leg 302, to prevent the second pivot element 60 from being exposed, thereby improving the appearance of the product.

Please refer to fig. 9 and 10. The second hinge 60 may include a second hinge body 61, a second rotating portion 62 disposed on the second hinge body 61 and rotatably connected to the first hinge 50, such as the first rotating portion 52, and a second magnetic element 63 mounted on the second rotating portion 62 and magnetically engaged with the first hinge 50, such as the first magnetic element 53.

The magnetic force between the second magnetic element 63 and the first pivot element 50, such as the first magnetic element 53, can make the first pivot element 50 and the second pivot element 60 rotate relatively, and rotate to a predetermined position for limiting.

The second hinge body 61 may be installed in a leg such as a receiving space. A mounting portion 611 may be provided on the second pivot body 61 to mount the second pivot body 61 on a leg, such as the first leg 301 and the second leg 302. In some embodiments, the mounting portion 611 is disposed on a side of the second pivot body 61 away from the first pivot member 50. In some embodiments, the mounting portion 611 may be a connection hole, a snap structure, a screw structure, or the like. In some embodiments, the second pivot body 61 can also be fixed to the legs, such as the first leg 301 and the second leg 302, by welding, plugging, clipping, bonding, etc. In some embodiments, second pivot body 61 is a unitary structure with legs, such as first leg 301 and second leg 302.

That is, the second contact portion 612 is disposed on a side of the second pivot body 61 away from the mounting portion 611.

In some embodiments, the second abutting portion 612 can have an elastic deformation capability, and further, when the second abutting portion 612 is elastically deformed when abutting against the first pivot component 50, such as the first abutting portion 512, a resilient force can be generated, so that the first leg 301 rotates to a side close to the second leg 302, and the second leg 302 rotates to a side close to the first leg 301.

Referring to fig. 9, the second rotating portion 62 may be located at one side of the second hinge body 61. In some embodiments, the second rotating portion 62 may be a rotating shaft. In some embodiments, the second rotating portion 62 may include a third connecting ear 621 and a fourth connecting ear 622 oppositely disposed and rotatably connected to the first pivot element 50, such as the first rotating portion 52. The third connecting lug 621 and the fourth connecting lug 622 rotate relative to the first pivot 50 around the rotation axis. In some embodiments, the third engaging lug 621 and the fourth engaging lug 622 may be disposed between the first rotating portion 52, such as the first engaging lug 521 and the second engaging lug 522. In some embodiments, the third engaging lug 621 and the fourth engaging lug 622 may be disposed on both sides of the first rotating portion 52. In some embodiments, the first connecting ear 521, the second connecting ear 522, the third connecting ear 621 and the fourth connecting ear 622 may be staggered. For example, the first engaging lug 521 is located between the third engaging lug 621 and the fourth engaging lug 622, and the third engaging lug 621 or the fourth engaging lug 622 is located between the first engaging lug 521 and the second engaging lug 522. For example, the second engaging lug 522 is located between the third engaging lug 621 and the fourth engaging lug 622, and the third engaging lug 621 or the fourth engaging lug 622 is located between the first engaging lug 521 and the second engaging lug 522.

Referring to fig. 9, the second magnetic assembly 63 may be disposed on the second rotating portion 62 and spaced apart from the second pivoting body 61, so as to arrange a circuit trace 70 (shown in fig. 11) of the control system in a gap between the second magnetic assembly 63 and the second pivoting body 61. It is understood that the second magnetic assembly 63 can be disposed on the second hinge body 61, in the case that the circuit trace 70 of the control system can be disposed between the second magnetic assembly 63 and the second hinge body 61.

The second magnet assembly 63 may include a second mounting plate 631 disposed on the second rotating part 62 and a second magnet 632 disposed on the second mounting plate 631.

The second mounting plate 631 may enable the second magnetic element 632 to be mounted on the second rotating portion 62, and may also enhance the stability of the second rotating portion 62, such as the third engaging lug 621 and the fourth engaging lug 622. For example, the second mounting plate 631 may be coupled to the third and fourth attachment ears 621 and 622. In some embodiments, the second mounting plate 631 may be disposed between the third and fourth attachment ears 621, 622.

The second mounting plate 631 may be disposed adjacent to the rotation shaft. In one embodiment, the second mounting plate 631 may be disposed on the shaft. In one embodiment, the second mounting plate 631 is disposed on a side of the first mounting plate 531 adjacent to the hinge. In one embodiment, the second mounting plate 631 is disposed on a side of the first mounting plate 531 remote from the pivot axis. To slide relative to the first pivot member 50, e.g., the first mounting plate 531, about the axis of rotation at the second mounting plate 631.

In one embodiment, the second rotating portion 62 can rotate relative to the first pivoting member 50, such as the first rotating portion 52, around the rotating shaft, and rotate to a position where the second mounting plate 631 abuts against the first pivoting member 50, such as the first abutting portion 512, so that the second pivoting body 61 and the first pivoting member 50, such as the first pivoting body 51, are in an abutting limit state.

The second magnetic member 632 may be a magnet or an electromagnet. In one embodiment, the second magnetic member 632 is an electromagnet and is electrically connected to a control system, such as the circuit trace 70.

The second magnetic element 632 is disposed on a surface of the second mounting plate 631 adjacent to the rotation axis to generate a magnetic force with the first pivot element 50, such as the first magnetic element 532. The second magnetic member 632 may be fixed on the second mounting plate 631 by a snap structure, a plug structure, an adhesive method, a welding method, or the like.

A side surface of the second magnetic element 632 close to the rotation axis may be a curved surface, and in some embodiments, a cross section of the curved surface in a radial direction of the rotation axis is a circular arc around the rotation axis to better match with the first pivot element 50, such as the first magnetic element 532.

In an embodiment, the second magnetic member 632 may be directly fixed to the second pivot body 61 and/or the second rotating portion 62 when the second mounting plate 631 is omitted.

It will be appreciated that in some embodiments, the second magnetic member 632 may be disposed on a surface of the second mounting plate 631 on a side thereof remote from the axis of rotation. The surface of the second magnetic member 632 away from the rotating shaft may be a curved surface. In some embodiments, for better lifting the magnetic force fit between the first magnetic member 532 and the second magnetic member 632, the first magnetic member 532 may be disposed on a side of the first mounting plate 531 close to the rotation axis, the second magnetic member 632 may be disposed on a side of the second mounting plate 631 away from the rotation axis, and the second mounting plate 631 is closer to the rotation axis than the first mounting plate 531.

It is also possible to arrange the first magnetic member 532 on the side of the first mounting plate 531 away from the rotation axis, and arrange the second magnetic member 632 on the side of the second mounting plate 631 near the rotation axis, wherein the first mounting plate 531 is closer to the rotation axis than the second mounting plate 631.

Referring to fig. 2, 11 and 12 together, fig. 11 is a cross-sectional view of the slack adjustment assembly 500 of fig. 8 in a first deployed state, and fig. 12 is a cross-sectional view of the slack adjustment assembly 500 of fig. 11 in a second deployed state. In fig. 2, the legs, e.g. first leg 301, second leg 302, are in an unfolded state. The state of the first pivot 50 and the second pivot 60 of the slack adjuster assembly 500 of fig. 11 corresponds to the extended state of the legs of fig. 2, such as the first leg 301 and the second leg 302. The coupling area of the first magnetic member 532 and the second magnetic member 632 coupled to each other on two opposite surfaces (i.e. two arc surfaces) is the largest, so that the magnetic force of the first magnetic member 532 and the second magnetic member 632 that are attracted to each other due to the different magnetic poles is the largest. The first abutting portion 512 is spaced from and does not abut the second abutting portion 612. Of course, the first abutment 512 may abut the second abutment 612. The circuit traces 70 are disposed between the first mounting plate 531 and the first pivot body 51, between the shaft and the second pivot body 61, and between the second mounting plate 631 and the second pivot body 61.

In fig. 2, when the legs, for example, the first leg 301 and the second leg 302, are rotated in the second direction B to be folded, the first leg 301 is rotated in the second direction B with respect to the frame 200 to the side closer to the second leg 302, and the second leg 302 is rotated in the second direction B with respect to the frame 200 to the side closer to the first leg 301. In fig. 11, the second pivoting member 60 rotates relative to the first pivoting member 50 in the third direction C, so that the coupling area between the first magnetic member 532 and the second magnetic member 632 is smaller, and the magnetic force between the first magnetic member 532 and the second magnetic member 632 is smaller (i.e. the coupling area between the first magnetic member 532 and the second magnetic member 632 is positively correlated with the magnetic force between the first magnetic member 532 and the second magnetic member 632). When the legs such as the first leg 301 and the second leg 302 in fig. 2 are in the folded state, the first magnetic member 532 and the second magnetic member 632 in fig. 11 are located such that the first magnetic member 532 and the second magnetic member 632 do not have magnetic forces with different magnetic poles and mutually attracting, thereby maintaining the legs such as the first leg 301 and the second leg 302 in fig. 2 in the folded state. It can be understood that, during the process of rotating the support legs such as the first support leg 301 and the second support leg 302 from the folded state to the unfolded state in fig. 2, the coupling area between the first magnetic element 532 and the second magnetic element 632 gradually increases, and the unfolding of the support legs such as the first support leg 301 and the second support leg 302 in fig. 2 is accelerated under the magnetic force of the magnetic poles of the first magnetic element 532 and the second magnetic element 632 that are attracted to each other, and the circuit trace 70 is not damaged.

When the legs such as the first leg 301 and the second leg 302 in fig. 2 rotate in the second direction B to continue to unfold, that is, the first leg 301 rotates in the second direction B away from the second leg 302 relative to the frame 200, and the second leg 302 rotates in the second direction B away from the first leg 301 relative to the frame 200, the second pivot 60 rotates in the fourth direction D relative to the first pivot 50 in fig. 11, so that the coupling area between the first magnetic member 532 and the second magnetic member 632 gradually decreases, and further the magnetic force between the first magnetic member 532 and the second magnetic member 632 decreases (that is, the coupling area between the first magnetic member 532 and the second magnetic member 632 and the magnetic force between the first magnetic member 532 and the second magnetic member 632 are in positive correlation). Under the magnetic force of the different magnetic poles between the first magnetic member 532 and the second magnetic member 632 attracting each other. The second pivot member 60 is rotated in the third direction C with respect to the first pivot member 50, and the first leg 301 is further rotated in the second direction B toward the second leg 302 with respect to the frame 200 in fig. 11, and the second leg 302 is rotated in the second direction B toward the first leg 301 with respect to the frame 200. That is, the magnetic forces of the first magnetic member 532 and the second magnetic member 632, which are attracted to each other due to the different magnetic poles, make the legs, such as the first leg 301 and the second leg 302, resilient.

The second pivot 60 of fig. 11 rotates in the fourth direction D relative to the first pivot 50 to a position where the first abutting portion 512 abuts against the second abutting portion 612 and/or a position where the second mounting plate 631 abuts against the first pivot body 51 of fig. 12.

It can be understood that, in the case that the first abutting portion 512 and/or the second abutting portion 612 can be abutted and elastically deformed, the elastic deformation of the first abutting portion 512 and the second abutting portion 612 cooperates with the magnetic force between the first magnetic member 532 and the second magnetic member 632, so that the second pivot element 60 rotates in the third direction C relative to the first pivot element 50.

Of course, when the first abutting portion 512 abuts against the second abutting portion 612 in fig. 11, the second pivot member 60 rotates in the fourth direction D relative to the first pivot member 50, and the first abutting portion 512 and/or the second abutting portion 612 can abut against and elastically deform. The second pivot member 60 rotates relative to the first pivot member 50 in the fourth direction D to a position where the second mounting plate 631 abuts against and limits the first pivot body 51.

Of course, when the first abutting portion 512 abuts against the second abutting portion 612 in fig. 12, the second pivot element 60 rotates in the fourth direction D relative to the first pivot element 50, and can rotate to a position where the second mounting plate 631 abuts against the first pivot body 51.

The user with a small head shape can be adapted through the adjusting piece 40, and the user with a large head shape can be adapted through the tightness adjusting assembly 500. In addition, the arrangement of the first and second magnetic assemblies 53 and 63 on the legs, such as the first and second legs 301 and 302, and the frame 300, can reduce the height of the legs, such as the first and second legs 301 and 302, in the axial direction of the rotating shaft, and also can reduce the width of the legs, such as the first and second legs 301 and 302, in the radial direction of the rotating shaft, without causing damage to the circuit traces 70, so that the structure of the head-mounted device 100 is more compact and beautiful.
