Description

Technical Field

[0001] This utility model relates to the field of head-mounted device support technology, and specifically discloses a multi-level hinged support that is compatible with different head-mounted devices. Background Technology

[0002] With the widespread application of head-mounted devices (such as night vision devices, thermal imagers, action cameras, etc.) in fields such as military reconnaissance, security detection, and outdoor observation, the demand for their mounting brackets is increasing.

[0003] Chinese patent (patent number: CN110500498B, disclosing a night vision device bracket) includes: a fixed plate, a rotating structure, and a curved arm connected in sequence. The fixed plate is used to connect to a helmet. The rotating structure is used to rotate the night vision device to switch between the user's left and right eyes. The curved arm is generally obtuse-angled, with one end fixedly connected to the rotating structure, the other end used to fix the night vision device with screws, and the middle section being a curved arm section used to connect to and support the body of the night vision device. The bending angle of the curved arm section is configured to bring the night vision device close to the user's eyes.

[0004] However, the aforementioned devices and existing technologies have significant drawbacks:

[0005] Firstly, it lacks compatibility. The single interface design cannot adapt to multiple types of devices, requiring users to frequently change the stand, increasing costs and operational complexity.

[0006] Secondly, the adjustment flexibility is limited. The fixed connecting arm only supports a limited number of adjustment levels and cannot achieve stepless extension or free angle adjustment, making it difficult to adapt to different head shapes or usage scenarios.

[0007] Third, the limited scalability and rigid support structure prevent functional expansion by adding or removing connecting arms or replacing modular interfaces. These issues severely restrict the practical efficiency and user experience of head-mounted devices, necessitating a new support solution to overcome existing technological bottlenecks. Utility Model Content
