Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of connecting bridge, specifically relates to a light weight connecting bridge. BACKGROUND

[0002] With the continuous development of science and technology, more and more enthusiasts begin to use head-mounted optical instruments, such as AR / VR glasses, action cameras, night vision goggles and other optical equipment. When using these instruments, users need to hold other devices or operate other instruments, so these devices usually need to be hung on the helmet to free the hands, which is generally achieved by various helmet accessories and bridges, and after installation, the use position of the optical equipment needs to be adjusted so that the human eye can be aligned with the optical instrument to achieve good visual effect. In addition, since binocular devices have better visual experience than monocular devices, binocular devices are more widely used than monocular devices. Traditional binocular night vision devices usually have a bridge, which can be directly installed on the helmet accessory through the interface on the bridge. However, with the development of infrared night vision and VR / AR device technology, more and more users use traditional monocular night vision goggles and infrared night vision goggles to form a binocular device to improve their situational awareness of the target. To achieve this function, a connecting bridge is needed, one side of the bridge can connect a traditional monocular night vision goggles, and the other side of the bridge can connect an infrared night vision goggles or a VR / AR device.

[0003] Most of the current bridges have the following defects:

[0004] 1. The mechanical structure of the traditional binocular device on both sides is locked and cannot be adjusted. However, in actual use, users sometimes need to retain the natural vision of one eye (i.e. the vision without optical device assistance) while observing through the optical device due to the use scene. Because the mechanical structure of the traditional binocular device is locked, users need to completely remove the optical device to obtain natural vision, which sacrifices the field of view of the optical device and the operation is very complex.

[0005] 2. Some bridges are designed with a flip structure that can achieve the above-mentioned lifting of one side of the device while retaining the natural vision of the other side of the device and the human eye. However, most bridges do not have a locking structure to maintain the current flipped state (such as patent CN111175963 and patent CN113189765A), which can easily cause the device to accidentally fall down and bump into the user. Especially in a motion scene, when the swing amplitude is too large, it affects the user experience.

[0006] Patent CN111175963 discloses a rotating mechanism of a low-light night vision instrument, which is composed of a rotating shaft, a support shaft seat, a battery compartment shaft seat, a conductive elastic contact, a support shaft seat and a sliding mechanism, is an integrated connecting bridge, can realize a turnover function, and can reserve the natural vision of the device and the human eye on one side at the same time. However, the bridge has no locking structure, and the turnover state of the device cannot be maintained, which is easy to cause the device to accidentally fall down and knock the user. Especially in the motion scene, when the swing amplitude is too large, the use experience is affected.

[0007] Patent CN113189765A discloses a modular single-double night vision instrument support composed of a middle bridge, a quick-mounting connecting piece, an arm connecting piece and an arm. The support is used as a common night vision instrument support and has strong universality. The support can carry two single night vision instruments and use the two single night vision instruments as common binocular double night vision instruments, and has strong expansibility. However, the bridge has no locking structure, and only the pre-pressing force of the screw can lock the rotating shaft. In the long-term use or motion scene, the turnover state of the device cannot be maintained, which is easy to cause the device to shake or accidentally fall down and knock the user.

[0008] 3. The dovetail interface connecting the optical device is often disassembled, and long-term wear and tear will cause gaps at the connection between the optical instrument and the bridge, and also cause the interface of the optical device to be worn out, and even completely damage the interface of the optical device. Moreover, if there is a gap between the optical device and the connecting bridge, the gap will cause the entire head-mounted system to shake violently when the user runs or does distance exercises, which not only causes the user to feel dizzy, but also has a high possibility of causing the optical instrument to injure the user.
