Description

Adjustable hinge for wearable devices The present invention relates to an adjustable hinge, and more particularly to a hinge applied to a wearable device, and can provide a more precise angle of use by allowing the angle to be further adjusted even after being rotated to a certain position. In the case of wearable devices, rotatable components are often installed to allow them to be folded or unfolded at specific angles. For example, a special-purpose visor may be installed on a helmet; the visor is connected to a base via a hinge, and the base is mounted on the helmet. When not in use, the visor is folded upward, and when in use, it is rotated downward to move to a position in front of the eyes. FIG. 1 is a schematic diagram of an embodiment of the present invention. FIG. 2 is a schematic diagram of the embodiment shown in FIG. 1 with the operating handle, main shaft, and damping structure omitted. FIG. 3 is a schematic diagram of a rotatable and adjustable rotating bracket in the embodiment shown in FIG. 1. Figure 4 is a schematic diagram of the main shaft and damping structure in the embodiment shown in Figure 1. Figure 5 is a schematic diagram of a connecting arm in the embodiment shown in Figure 1. FIG. 6 is a schematic diagram of the adjustment handle and eccentric shaft connecting components in the embodiment shown in FIG. 1. Referring to the drawings, the present invention provides an adjustable hinge for a wearable item, comprising a base (1) and a rotating bracket (2). The base is used for connection to a main body of the wearable item, such as a helmet, and the rotating bracket is used for connection to a functional part of the wearable item, such as a visor. A mounting block (20) is installed on the rotating bracket (2), and the mounting block (20) is installed so as to be adjustable in the forward and backward directions on the rotating bracket (2). A rack (21) may be installed along the length of the rotating bracket (2), and a locking head that engages with the rack (21) and is supported by a spring is installed on the mounting block (20), and the functional part is connected to the mounting block (20) so that its position can be adjusted in the forward and backward directions. The first and second sides of the rotating bracket (2) are each rotatably connected to the base (1) via a main shaft (3), and the main shaft (3) is a rotatable shaft. The rotating bracket (2) is connected to the main shaft (3) through a clutch mechanism so that between an initial position (e.g., a folding angle at which the rotating bracket (2) is in close contact with the helmet) and a working angle (e.g., the rotation angle may be about 90° when the visor is positioned in front of the eyes), the rotating bracket (2) is rotatable relative to the main shaft (3), and at the working angle, the rotating bracket (2) is connected to the main shaft (3) and rotates synchronously. The adjustable hinge is also equipped with a main shaft rotation adjustment mechanism for the main shaft (3), and the main shaft rotation adjustment mechanism includes an adjustment arm (4) that is fixedly connected to the main shaft (3) and rotates synchronously with the main shaft (3). In addition, the main shaft rotation adjustment mechanism includes a adjustment arm rotation damping structure, thereby allowing the current rotation angle of the rotation bracket to be set by stopping the rotation of the adjustment arm, and also maintains the main shaft (3) so that it does not rotate even when the clutch mechanism is in a disengaged state and the rotation bracket (2) is rotatable relative to the main shaft (3). The above-described main shaft rotation adjustment mechanism also includes an adjustment handle (5), the adjustment handle (5) is connected to an adjustment arm (4) through a rotation mechanism to drive the adjustment arm (4) clockwise and counterclockwise to rotate it, and the rotation damping structure acts on the rotation mechanism. The above-described rotation mechanism includes an eccentric shaft (6), and the adjustment handle (5) is connected to the eccentric shaft (6) and rotates synchronously with it, driving the adjustment arm (4) to rotate it. The eccentric shaft (6) is rotatably connected to the base (1) through the adjustment shaft (61), and the adjustment shaft (61) is parallel to the main shaft (3). Additionally, the damping structure is connected between the eccentric shaft (6) and the non-rotating component through a friction structure. The damping structure comprises a friction structure and a first elastic member (62) (e.g., a plurality of disc springs) configured to press the friction structure, and the friction structure comprises a non-rotating portion. For example, it may be implemented as a stationary friction plate (63), which is fitted onto a control shaft (61), and rotation may be prevented by the cooperation between the flat portion (631) above it and the stopper portion of the wearable item. The control shaft (61)
