Description

Technical Field

[0001] This utility model relates to the field of night vision device bracket technology, and in particular to an anti-glare night vision device bracket for use on a ship's bridge. Background Technology

[0002] Ship night vision devices are important navigation aids to ensure safe navigation at night. They can enhance the driver's visual perception in low-light environments, enabling timely identification of obstacles, oncoming vessels, and buoys in the waterway, and play a key role in preventing nighttime collisions.

[0003] Currently, night vision devices used on ships are mainly divided into two types: one is a fixed night vision device, which is fixedly installed on the ship's bridge or mast with a special bracket and connected to the ship's electrical system to achieve continuous and uninterrupted operation; the other is a handheld night vision device, which is flexibly used by the user when needed to obtain target information through visual observation.

[0004] While fixed night vision devices can achieve continuous monitoring, their installation position and lens orientation are difficult to adjust once set, resulting in a relatively fixed observation angle and coverage area, significant blind spots, and an inability to provide omnidirectional observation of the vessel's surroundings. This is especially problematic during vessel turns or emergency collision avoidance, where rapid response to changes in observation needs is difficult. Handheld night vision devices offer advantages such as flexibility and adjustable pointing, but prolonged handheld operation can cause user fatigue. Furthermore, during vessel navigation, the swaying caused by wind and waves reduces device stability, making it difficult to obtain clear and stable images.

[0005] Both types of night vision devices share a common technical flaw: neither is equipped with an effective anti-glare structure. When a ship is navigating at night and encounters strong sunlight, the strong light shining on the lens from the side can easily cause glare, leading to overexposure, reduced contrast, and in severe cases, even temporary failure of the imaging device, thus increasing the safety hazards of nighttime lookout. Furthermore, existing products generally lack sufficient image stabilization performance. Whether due to ship vibration or hand-held shaking, the resulting shaking can also cause glare in the night vision device, resulting in blurred images, affecting target identification efficiency and accuracy, and making it difficult to meet the actual needs of use in complex sea conditions. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, this utility model provides an anti-glare night vision device bracket for ship bridge.

[0007] The technical solution of this utility model is implemented as follows: An anti-glare night vision device bracket for a ship's bridge includes a bracket body, one end of which is connected to a fixed base, and the other end of which is connected to an anti-glare mechanism. The anti-glare mechanism includes a pan-tilt unit for mounting the night vision device and a light shield for shading the night vision device. The light shield is detachably mounted on the side of the pan-tilt unit.

[0008] Preferably, the gimbal has a mounting groove on its side for mounting the light shield, the light shield is detachably connected to the mounting groove, and the inner side of the light shield has a protrusion that fits the mounting groove, the protrusion passing through the mounting groove.

[0009] Preferably, the upper surface of the pan-tilt head is provided with a mounting base for mounting a night vision device, and the upper surface of the mounting base is provided with a snap-fit ​​groove for mounting the night vision device, and a limiting member is provided at the opening of the snap-fit ​​groove.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-3 This utility model is an anti-glare night vision device bracket for ship bridge, including bracket body 1, one end of bracket body 1 is connected to fixed base 2, and the other end of bracket body 1 is connected to anti-glare mechanism 3. Anti-glare mechanism 3 includes pan-tilt unit 4 for placing night vision device and light shield 5 for shielding night vision device. Light shield 5 is detachably installed on the side of pan-tilt unit 4.

[0018] Specifically, the gimbal 4 has a mounting groove 401 on its side for mounting a light shield 5. The light shield 5 is detachably connected to the mounting groove 401. The inner side of the light shield 5 has a protrusion 501 that is adapted to the mounting groove 401. The protrusion 501 passes through the mounting groove 401.

[0019] In this embodiment, the fixing base 2 adopts a vacuum suction cup structure, which is suitable for rapid installation on the smooth surface of the ship's bridge. The suction cup part 9 is made of high-strength rubber material, which has excellent sealing and adsorption force. A fixing handle 10 is provided at the center of the top of the suction cup part 9. By moving the fixing handle 10, a negative pressure can be formed inside the suction cup part 9, thereby achieving stable adsorption.

[0020] Furthermore, the adjustment seat 11 is fixedly mounted on the upper surface of the suction cup part 9 via the support member 12. The adjustment seat 11 includes a first rotating part 1101 and a second rotating part 1102. The first rotating part 1101 is rotatably connected to the support member 12 via a first rotating adjustment part 13, so that the first rotating adjustment part 13 can rotate vertically on the support member 12. The second rotating part 1102 is rotatably connected to the first rotating part 1101 via a second rotating adjustment part 14, so that the second rotating part 1102 can rotate horizontally on the first rotating part 1101. This double-layer rotating structure provides the bracket with basic angle adjustment capability.

[0021] In this embodiment, the support body 1 is a double-arm structure, consisting of a first support arm 101 and a second support arm 102. The lower end of the first support arm 101 is rotatably connected to the second rotating part 1102 of the fixed base 2 via a rotating joint. This rotating joint is equipped with a locking knob 15, which can be adjusted and locked within a range of 0-360°. The upper end of the first support arm 101 is rotatably connected to the lower end of the second support arm 102 via the locking knob 15. This joint also supports angle adjustment and locking within a range of 0-360°.

[0022] The upper end of the second support arm 102 is connected to the gimbal 4 via a rotating component 8. The rotating component 8 adopts a universal joint structure, which enables the gimbal 4 to be flexibly adjusted. The first support arm 101 and the second support arm 102 are made of lightweight, high-strength aluminum alloy material, and the interior can be filled with damping material to absorb vibration.

[0023] Furthermore, the anti-glare mechanism 3 consists of a pan-tilt unit 4 and a light shield 5. The pan-tilt unit 4 is platform-shaped, with a mounting base 6 on its upper surface. A snap-fit ​​groove 601 is formed on the upper surface of the mounting base 6, and the cross-sectional shape of the snap-fit ​​groove 601 matches the bottom contour of a common handheld night vision device. A limiting member 7 is provided at the opening of the snap-fit ​​groove 601. In this embodiment, the limiting member 7 adopts a spring pin structure. When the night vision device is inserted into the snap-fit ​​groove 601, the spring pin automatically pops out to limit and fix the night vision device, preventing it from slipping out. Mounting slots 401 are formed on the left and right sides of the pan-tilt unit 4.

[0024] Specifically, the light shield 5 is made of an opaque, lightweight material, such as carbon fiber composite material, and its inner surface has a protrusion 501 that matches the shape of the mounting groove 401. During installation, the protrusion 501 is slid into the end of the mounting groove 401, thus achieving a detachable connection between the light shield 5 and the pan-tilt unit 4. The light-blocking range of the light shield 5 can be adjusted by adjusting the distance the protrusion 501 slides into the mounting groove 401. The light-blocking depth of the light shield 5 is designed to be 5-10 cm to effectively block stray light from the sides and rear without affecting the normal field of view of the night vision device. The inner wall of the light shield 5 can be frosted or coated with a matte coating to further reduce light reflection.

[0025] In this embodiment, the night vision device is electrically connected to the display screen on the ship's bridge, ensuring that it can transmit images to the display screen in real time when used in a fixed position. When it needs to be used alone, the data transmission cable between the night vision device and the display screen can be disconnected.

[0026] The working principle of the anti-glare night vision device bracket for ship bridge provided by this utility model is as follows: During installation, first select a suitable location on the ship's bridge, such as the control panel surface, and press the fixing handle 10 to firmly attach the suction cup 9. Then, according to usage requirements, slide the protrusion 501 of the sunshade 5 into the mounting slot 401 on the side of the gimbal 4 to complete the assembly of the anti-glare mechanism 3. Next, insert the bottom of the handheld night vision device into the snap-fit ​​slot 601, and the limiting member 7 automatically locks the night vision device. Finally, adjust the night vision device to the required observation angle and lock all joints by adjusting the locking knob 15 and the rotating member 8. When the ship is sailing in a bright light environment, the installed sunshade 5 can effectively block side incident light and prevent glare. In open waters with low light, the sunshade 5 can be removed to reduce weight and wind resistance. The suction cup base makes it easy to adjust the installation position according to the navigation conditions, such as installing it on the inside of the windshield when entering port, and quickly moving it to the side window position when reversing.

[0027] This utility model provides an anti-glare night vision device bracket for a ship's bridge. The device, by setting up a light shield 5 that is easy to disassemble and has an adjustable blocking range, can greatly reduce the probability of glare from the night vision device when used with a gimbal 4. At the same time, the bracket body 1 can rotate at multiple angles and can be used with a detachable fixed base 2 to adapt to the usage needs of different positions. Under the suction of the fixed base 2, the bracket body 1 can be firmly attached to the horizontal surface, ensuring that the position of the bracket body 1 is fixed when the ship is rocking, thus keeping the transmitted image of the night vision device fixed.
