[0016] As shown in the drawings, the adjustable hinge for an attachment provided by the present invention includes a base 1 and a rotary support 2. Among them, the base is used for applications where it is connected to the attachment body, such as a helmet. The rotary support is used for applications where it is joined to a functional component of the wearable article, such as an eyepiece. The rotary support 2 is provided with a mounting block 20. The mounting block 20 is disposed on the rotary support 2 so as to be adjustable back and forth. The rotary support 2 is provided with a rack 21 along its length direction. The mounting block 20 is provided with a locking head that is meshingly connected to the rack 21 and supported by a spring. The functional article is connected to the mounting block 20 to enable front-rear position adjustment.

[0017] The first side and the second side of the rotary support are respectively connected to the base 1 through the main shaft 3. The main shaft 3 is a rotatable shaft. The rotary support 2 and the main shaft 3 are connected via a clutch mechanism, and between the original position (for example, the folding angle at which the rotary support 2 approaches the helmet) and the working angle (for example, the eyepiece is placed in front of the eyes, and the rotation angle is approximately 90°), the rotary support 2 can rotate relative to the main shaft 3, and at the working angle, the rotary support 2 can rotate synchronously with the main shaft 3. The adjustable hinge is further provided with a main shaft rotation adjustment mechanism for the main shaft 3. The main shaft rotation adjustment mechanism includes an adjustment arm 4 fixedly connected to the main shaft 3. The main shaft 3 and the adjustment arm 4 rotate synchronously. The main shaft rotation adjustment mechanism further includes an adjustment arm rotation damping structure. By stopping the rotation of the adjustment arm, the current rotation angle of the rotary support can be positioned, and when the clutch mechanism is disengaged so that the rotary support 2 can rotate relative to the main shaft 3, the main shaft 3 will not rotate.

[0018] The spindle rotation adjustment mechanism further comprises an adjustment handle 5. The adjustment handle 5 is connected to the adjustment arm 4 through a rotation mechanism, can drive the adjustment arm 4 to rotate in both clockwise and counterclockwise directions, and the rotation damping structure acts on the rotation mechanism.

[0019] The rotation mechanism comprises an eccentric shaft 6. The adjustment handle 5 is connected to the eccentric shaft 6 and rotates synchronously. It drives the rotation of the adjustment arm 4, and the eccentric shaft 6 is connected to the base 1 through the adjustment shaft 61. The adjustment shaft 61 is parallel to the spindle 3, and the damping structure is connected between the eccentric shaft 6 and the non-rotating member through a friction structure.

[0020] The damping structure comprises a first elastic element 62 (for example, several disc springs) used for abutting between friction structures. The friction structure comprises a non-rotatable part, for example, a static friction plate 63, which is fitted over the adjustment shaft 61, and is engaged with the stop part on the mounting member through the flat portion 631 thereon so as not to be rotatable. The adjustment shaft 61 is connected to the non-rotatable part (static friction plate 63), and the adjustment shaft 61 is connected to the eccentric shaft 6 to rotate synchronously (for example, the shaft hole 64 of the eccentric shaft 6 and the adjustment shaft 61 are connected through a flat portion to realize synchronous rotation). The rotatable part in the friction structure adopts the eccentric shaft 6 or a member that rotates synchronously with the eccentric shaft (for example, a partial structure of the operation handle 5), and is frictionally fitted under the condition that the friction plate 63 and the first elastic element 62 are in firm abutment.

[0021] The connection between the eccentric shaft 6 and the adjustment arm 4 is realized by providing a groove 40 inside the adjustment arm to accommodate the eccentric shaft 6 or a member on the eccentric shaft. When the eccentric shaft 6 rotates, it drives the synchronous rotation of the adjustment arm 4 and the spindle 3 through the eccentric shaft 6 or the member thereon.

[0022] The rotating support 1 is movably fitted onto the spindle 3 through a circular hole. The clutch mechanism includes a dynamic cam 71 connected to the rotating support 1 and rotating synchronously with it, and a static cam 72 connected to the spindle 3 and rotating synchronously with it. The clutch mechanism has the dynamic cam 71 and the static cam 72 positioned on the first and second sides of the rotating support 2, respectively. The dynamic cam 71 and the static cam 72 are firmly pressed against each other through elastic elements (e.g., several disc springs 74). Between the dynamic cam 71 and the static cam 72, there is a fitting structure (e.g., a structure in which a groove and a projection fit together) that is coupled together at the working angle, and when rotating between the original position and the working angle, the projection 731 fits into the plane 732. When in operation, the projection 731 engages with the groove 733, and by utilizing this engagement between the groove 733 and the projection 731, the dynamic cam 71 and the rotation support 2 are driven via the main shaft 3 and the static cam 72, allowing for fine adjustment of the rotation support angle.
