[0024] Refer to the accompanying drawings. The adjustable hinge of the wearable product provided by the present invention includes a first main body 100 and a rotating arm 200, the first end of the rotating arm 200 is rotatably connected to the first main body 100 through a first rotating connection structure, and the second end of the rotating arm 200 is connected to the second rotating connection structure. Taking the wearable product as a helmet as an example, the first main body 100 is located at the end connected to the helmet and the second rotating connection structure is used to connect a device, such as an eyepiece. Through the design of the dual rotation center solution, the position and angle of the device in the up and down directions and the front and back directions can be adjusted to meet the needs of different users for field of view and focus, and the product can be rotated to normal use, short rest and long-term non-use states, which is easy to operate. Furthermore, the first main body 100 of the adjustable hinge is slidably connected to the second main body 400, and the sliding direction is perpendicular to the first axis 10 of the first rotating connection structure and the second axis 60 of the second rotating connection structure, so as to further increase the adjustment range in the Z direction to meet the requirements of different users. The hinge is provided with a locking structure of the first body 100 and the second body 400 and an operating key 401 thereof. The locking structure may include a rack 402 along the sliding direction. The operating key 401 is supported by a spring 403 and is provided with teeth engaged with the rack 402 .

[0025] The first rotating connection structure includes a first shaft 10, a first torsion mechanism, a second torsion mechanism and a third torsion mechanism. The direction of action of the third torsion mechanism is to always drive the rotating arm 200 to rotate in the folding direction. The first torsion mechanism includes a first cam matching structure, a first elastic component 11 and a first friction plate 12, and provides high torque when the rotating arm 200 is in the working angle range, provides locking force when the rotating arm 200 is at the folding angle, and provides low torque between the folding angle and the working angle. The second torsion mechanism adopts a structure in which the first reed tube 21 clamps the first shaft 10, and the reed tube is an elastic sleeve with an axial opening. The third torsion mechanism adopts a torsion spring 3

[0026] Through a multi-torque module design involving cams, torsion springs, and spring tube friction, variable torque at different angles is achieved to meet the varying torque and functional requirements of the device in various positions and states. Between the folded angle and the working angle, a hovering angle range is formed by the combined action of the first, second, and third torque mechanisms. The torque required to rotate the rotating arm 200 within the hovering angle range is less than the torque required to rotate the rotating arm 200 within the working angle range. The torque required to rotate the rotating arm 200 within the working angle range is greater than the torque required to rotate the rotating arm 200 within the hovering angle range. In this embodiment, the rotation angle from the maximum working angle (0°) to the folded state is 195°. The working angle range is 0-45°, enabling high-torque free parking. At 195°, the folded angle is reached. From the folded state to the working angle range, torque is adjusted by the cam and torsion spring. When rotating upward, torque is lower, meeting user requirements for easy operation. Above the working angle range is the hovering angle range. When the user is taking a break, the device needs to be rotated to an area outside the field of vision for temporary docking. When needed, the device can be quickly returned to the working angle range by simply turning down a smaller angle.

[0027] In this embodiment, the first cam engagement structure includes a first movable cam 13 and a first static cam 14 mounted on the first shaft 10. The first shaft 10 is connected to the rotating arm 200 (e.g., by welding, interference fit, or flattening and snap-fitting) for synchronous rotation. The first movable cam 13 and the first shaft 10 are connected (e.g., flattened) for synchronous rotation. The first static cam 14 is fixed and cannot rotate with the first shaft 10. Both the first movable cam 13 and the first static cam 14 are displaceable in the axial direction of the first shaft 10. The first cam engagement structure and the first friction plate 12 are compressed by a first elastic member 11, which can be a stack of multiple disc springs. The first static cam 14 in the first cam engagement structure is provided with a groove 141 corresponding to the retracted angle of the rotating arm, a convex platform 142 corresponding to the operating angle range, and a groove range 143 corresponding to the low torque range. The torque required for hovering in the low torque range is compensated by the torque output by the spring tube 21 of the second torque mechanism clamping the first shaft 10.

[0028] In the second torsion mechanism, the first reed tube 21 is fixed, and the torsion spring 3 is sheathed around the first elastic component 11. One end leg 31 of the torsion spring 3 is plugged into the first movable cam 13, while the other end leg 32 is plugged into the first reed tube 21. A first nut 15, threadedly connected to the first shaft 10, is positioned between the first elastic component 11 and the first reed tube 21 to axially limit the first elastic component 11 and the first reed tube 22.

[0029] The first body 100 defines a first cavity 101 for accommodating the first and second torsion mechanisms and the torsion spring 3. The first spring tube 21 and the first static cam 14 are secured against rotation by radial projections 210 and 140, respectively, that engage with grooves 105 in the wall of the first cavity 101. These grooves allow the torsion spring legs to pass through, facilitating structural arrangement. The first friction plate 12 consists of a dynamic friction plate and a static friction plate. The static friction plate is fixed to the groove 105 in the first cavity 101 via projections 120, preventing rotation. The dynamic friction plate is connected to the first shaft 10 and rotates therewith.

[0030] The first shaft 10 passes through the first cavity 101, and the first reed tube 21, the first nut 15, the gasket 16, the first elastic component 11, the first moving cam 13, the first static cam 14, the first friction plate 12, and the cavity cover 102 are sequentially sleeved on the outside of the first shaft, and a cavity sealing structure 103 is provided at the cavity mouth. The rotating arm 200 is connected to one end of the first shaft 10 on the outside of the cavity cover 103, and the other end of the first shaft 10 is connected to the second nut 104.

[0031] The second rotation mechanism includes a second shaft 60, a fourth torsion mechanism, and a fifth torsion mechanism. The second shaft 60 is parallel to the first shaft 10. The adjustable hinge is further provided with a fixed seat 300, which can be connected to a connector of a device (such as an eyepiece). The fixed seat 300 and the second shaft 60 are fixedly connected and rotate synchronously (such as a flat connection). The fourth torsion mechanism includes a second cam matching structure, a second elastic component 41, and a second friction plate 42. The fifth torsion mechanism adopts a structure in which the second reed tube 51 clamps the second shaft 60. The second elastic component 41 can be a plurality of disc reeds.

[0032] The second cam engagement structure includes a second dynamic cam 43 and a second static cam 44 mounted on a second shaft 60. The second shaft 60 is connected to a fixed base 300 for synchronous rotation. The second dynamic cam 43 and the second shaft 60 are connected together (e.g., by flat engagement) for synchronous rotation. The second static cam 44 is fixed and cannot rotate with the second shaft 60. The second end of the rotating arm 200 is provided with a second cavity 201 for accommodating the fourth and fifth torsion mechanisms. The second reed tube 51 and the second static cam 44 are respectively provided with radial protrusions 510 and 440 that engage with grooves on the wall of the second cavity 201, thereby securing them and preventing rotation. The second friction plate 42 is composed of a dynamic friction plate and a static friction plate. The static friction plate is connected to the groove in the second cavity 201 via protrusions 420 for synchronous rotation. The dynamic friction plate is connected to the second shaft 60 for synchronous rotation.

[0033] The second shaft 60 passes through the second cavity 201 and is connected to the fixed seat 300. The second reed tube 51, the second friction plate 42, the second cam matching structure, the second elastic component 41, and the third nut 45 are sequentially sleeved on the outside of the second shaft 60, and sealing structures 202 and 203 are respectively provided at the ends of the second cavity 201. The third nut 45 is threadedly connected to the second shaft 60.

[0034] The second static cam 44 has a convex platform 441 corresponding to the first end of the second axis's rotation limit and a convex platform 442 corresponding to the second end of the second axis's rotation limit, so as to provide a hovering function in a rotation range before the first end of the rotation limit (for example, 30 degrees), and can accurately adjust the angle of the second axis when the rotating arm rotates to the working angle range (which also determines the distance and height in the front-to-back direction. Taking the eyepiece as an example, after the eyepiece is placed in front of the eyepiece and the distance between the eyepiece and the glasses is determined, the angle of the eyepiece can be further accurately adjusted). A hovering function is provided in a rotation range before the second end of the rotation limit to facilitate positioning when folded. The second static cam 44 has a groove section 443 between the convex platform 441 at the first end of the rotation limit and the convex platform 442 at the second end of the rotation limit; the second torque mechanism is used to increase the torque in the angle range corresponding to the groove section 443 between the convex platform 441 at the first end of the rotation limit and the convex platform 442 at the second end of the rotation limit, so as to ensure a fast response of the second axis and prevent a loose feel.

[0035] The second end of the rotation limit is the rotation end point of the second shaft 60 in the same direction as the lifting rotation direction of the rotating arm 200, the first end of the rotation limit is the rotation end point of the second shaft 60 in the opposite direction, and the second shaft rotation angle range corresponding to the convex platform 441 at the first end of the rotation limit is the range of adjusting the second shaft rotation angle within the working angle range.

[0036] The hinge adopts a double-arm structure, and is provided with a rotating arm 200 on the left and a rotating arm 200 on the right. The rotating arms 200 on both sides are respectively rotatably connected to the first main body 100 through their respective first rotating connection structures. The second rotating connection structure is provided with a whole second shaft 60. The left end of the second shaft 60 is rotatably connected to the rotating arm 200 on the left through the second rotating connection structure on the left, and the right end is rotatably connected to the rotating arm 200 on the right through the second rotating connection structure on the right.
