Description

Technical Field

[0001] This utility model relates to the field of outdoor monitoring technology, and in particular to a multi-angle rotating anti-shake mechanism for security monitoring. Background Technology

[0002] In the field of security monitoring, the effective coverage and image stability of monitoring equipment are the core elements that determine the quality of monitoring, and are directly related to the realization of key security functions such as abnormal event identification and post-event tracing. With the upgrading of monitoring requirements in smart cities, smart parks, and other scenarios, traditional fixed-view monitoring equipment, due to its limited coverage and blind spots, can no longer meet the needs of full-area monitoring in complex environments. Monitoring equipment with multi-angle rotation capabilities is gradually becoming the mainstream. Such rotating monitoring equipment typically achieves dynamic coverage of a large area through a design of continuous 360° horizontal rotation and vertical pitch adjustment from -90° to 90°. However, the jitter problem encountered during its rotation has become a key bottleneck restricting the clarity of the monitoring image. The jitter is caused by multiple factors: First, the inherent defects of the equipment's own transmission system, such as torque fluctuations during motor operation, gear meshing clearance, bearing wear, and other mechanical errors, will generate periodic vibrations during rotation. Second, external environmental interference, such as wind in outdoor monitoring scenarios, ground vibrations caused by passing vehicles, and slight shaking of the mounting bracket caused by personnel activities in indoor monitoring. Third, installation limitations, some monitoring equipment needs to be installed on unstable carriers such as utility poles and tower cranes, and the shaking of the carrier itself will be directly transmitted to the monitoring subject.

[0003] For example, Chinese patent CN214368956U discloses a security camera with an adjustable function. The anti-shake mechanism includes an outer ring, a first rotating shaft installed on the inner wall of the outer ring, an inner ring inside the outer ring, the outer ring being connected to the inner ring via the first rotating shaft, a second rotating shaft installed on the inner wall of the inner ring, an anti-shake block inside the inner ring, the inner ring being connected to the anti-shake block via the second rotating shaft, a gravity block installed at the bottom of the anti-shake block, and a frustum installed at the top of the anti-shake block. When the device adjusts its angle, it may vibrate. The first rotating shaft on the outer ring will rotate to make the outer ring vibrate up and down without affecting the inner ring. When the inner ring vibrates, the second rotating shaft will rotate to make the inner ring vibrate up and down while maintaining the stability of the anti-shake block. The gravity block helps to prevent the anti-shake block from vibrating.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: outdoor-installed cameras are easily affected by lateral winds, causing them to sway left and right; indoor-installed cameras, if close to passageways, will cause the bracket to vibrate laterally when people walk around, and the existing dual-axis structure cannot compensate for this kind of horizontal shaking. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing technology has the disadvantage that cameras are easily affected by lateral wind force, resulting in left and right swaying. To this end, we propose a multi-angle rotation anti-shake mechanism for security monitoring.

[0006] To achieve the above objectives, this application adopts the following technical solution: a security monitoring multi-angle rotation anti-shake mechanism, including an anti-shake component, a camera is provided at the upper end of the anti-shake component, the anti-shake component includes a fixed column, a sliding groove is provided on one side of the fixed column, the interior of the fixed column is hollow, a drive motor is fixedly installed inside the fixed column, a lead screw is fixedly installed at the drive end of the drive motor, the lower end of the lead screw is rotatably connected to the fixed column, a connecting block is threaded on the outer side of the lead screw, an anti-shake disk is provided on one side of the connecting block, and the camera is rotatably positioned at the upper end of the anti-shake disk; The anti-shake disk has a second drive motor fixedly installed inside. The drive end of the second drive motor passes through the anti-shake disk and is fixedly installed with a connecting plate. The upper end of the anti-shake disk has a T-shaped ring groove. Multiple sets of sliders are rotatably installed inside the T-shaped ring groove. A limit ring is fixedly installed on the upper end of the slider. The limit ring matches the T-shaped ring groove. Multiple sets of connecting rods are fixedly installed on the upper end of the limit ring. All sets of connecting rods are fixedly connected to the connecting plate. A U-shaped connecting block is fixedly installed on the upper end of the connecting plate. A drive motor is set on one side of the U-shaped connecting block. The drive end of the drive motor passes through one side of the U-shaped connecting block and is fixedly installed with a rotating shaft. A semi-circular fixed shell is fixedly installed on the outer side of the rotating shaft. The semi-circular fixed shell is fixedly connected to the lower end of the camera. Two sets of arc grooves are opened on the semi-circular fixed shell. A fixing rod is slidably installed inside the arc groove. Both ends of the fixing rod are fixedly installed on the inner side of the U-shaped connecting block.

[0007] Preferably, the lower end of the fixing column has multiple sets of heat dissipation holes.

[0008] Preferably, a connector is fixedly installed at the upper end of the fixed column, and multiple sets of bolts are provided on the connector.

[0009] Preferably, at least four sets of connecting rods are provided.

[0010] Preferably, sealing plates are provided at the upper and lower ends of the connecting block, and the sealing plates are in close contact with the outer side of the fixed column and are slidably connected to it.

[0011] Preferably, a damping shock absorber is fixedly installed at the connection between the rotating shaft and the U-shaped connecting block.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, a fixed column provides a stable installation foundation and lifting adjustment function, ensuring reliable overall installation and adaptability to monitoring needs at different heights. When encountering horizontal vibrations, the drive motor inside the anti-shake disc rotates the connecting disc to adjust the horizontal angle. Simultaneously, the slider in the T-shaped groove cooperates with the limiting ring, and the conical traction force formed by multiple connecting rods limits the radial displacement of the connecting disc, thus counteracting horizontal shaking. The rotating shaft on the U-shaped connecting block cooperates with the semi-circular fixed shell to achieve vertical rotation of the camera. The fixed rod slides in the arc groove to provide guidance and constraint, further suppressing lateral vibration. At the same time, the damping shock absorber absorbs the vibration energy of the rotating shaft, and the silicone pad buffers the camera's own vibration. The multi-mechanism linkage forms a multi-level horizontal anti-shake system, effectively compensating for horizontal shaking caused by outdoor wind, and taking into account both the flexibility of multi-angle adjustment and the stability of the monitoring image.

Detailed Implementation

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figure 1 As shown, this utility model provides a technical solution: a security monitoring multi-angle rotation anti-shake mechanism, including an anti-shake component 1, and a camera 2 is provided at the upper end of the anti-shake component 1.

[0017] Reference Figure 1-2 As shown in this embodiment: the anti-shake component 1 includes a fixed post 11, with multiple sets of heat dissipation holes 111 at the lower end of the fixed post 11, and a connector 113 fixedly installed at the upper end of the fixed post 11. Multiple sets of bolts 114 are provided on the connector 113. A sliding groove 112 is provided on one side of the fixed post 11. The interior of the fixed post 11 is hollow. A drive motor 12 is fixedly installed inside the fixed post 11. A lead screw 121 is fixedly installed at the drive end of the drive motor 12. The lower end of the lead screw 121 is rotatably connected to the fixed post 11. A connecting block 122 is threaded onto the outer side of the lead screw 121. 122 is matched with the slide 112. Sealing plates 123 are respectively provided at the upper and lower ends of the connecting block 122. The sealing plates 123 are closely attached to the outside of the fixed column 11 and are slidably connected to it. A stabilizing disk 124 is provided on one side of the connecting block 122. The camera 2 is rotatably mounted on the upper end of the stabilizing disk 124. When the device is in use, it is fixed in the monitoring position by the connecting piece 113 and multiple sets of bolts 114. The drive motor 12 drives the lead screw 121 to rotate, thereby driving the connecting block 122, the stabilizing disk 124 and the camera 2 to move up and down, so as to adjust the monitoring angle.

[0018] Reference Figure 2-3As shown in this embodiment: a second drive motor 125 is fixedly installed inside the anti-shake disk 124. The drive end of the second drive motor 125 passes through the anti-shake disk 124 and is fixedly installed with a connecting disk 1244. A T-shaped annular groove 1241 is opened at the upper end of the anti-shake disk 124. Multiple sets of sliders 1242 are rotatably installed inside the T-shaped annular groove 1241. A limit ring 1243 is fixedly installed at the upper end of the slider 1242. The limit ring 1243 matches the T-shaped annular groove 1241. Multiple sets of connecting rods 1245 are fixedly installed at the upper end. All sets of connecting rods 1245 are fixedly connected to the connecting plate 1244. When it is necessary to adjust the horizontal rotation angle of the camera 2, the connecting plate 1244 and the camera 2 at the upper end are rotated together by controlling the drive motor 125. At the same time, in windy weather, the connecting plate 1244 is restricted by the conical traction force of the connecting rods 1245 and the slider 1242 during the rotation process, so that the connecting plate 1244 and the camera 2 maintain stable rotation.

[0019] Reference Figure 3-6 As shown in this embodiment: A U-shaped connecting block 126 is fixedly installed on the upper end of the connecting plate 1244. A drive motor 1261 is provided on one side of the U-shaped connecting block 126. The drive end of the drive motor 1261 passes through one side of the U-shaped connecting block 126 and is fixedly installed with a rotating shaft 1262. A semi-circular fixing shell 1266 is fixedly installed on the outer side of the rotating shaft 1262. The semi-circular fixing shell 1266 is fixedly connected to the lower end of the camera 2. Two sets of arc grooves 1264 are provided on the semi-circular fixing shell 1266. A fixing rod 1265 is slidably arranged inside the arc grooves 1264. The two ends of the fixing rod 1265 are fixedly installed on the inner side of the U-shaped connecting block 126. When the camera 2 needs to rotate vertically, the... The starting drive motor 1261 drives the rotating shaft 1262 and its outer semi-circular fixed shell 1266 to rotate, thereby causing the camera 2 to rotate vertically to expand the monitoring area. At the same time, during the rotation, the semi-circular fixed shell 1266, under the constraint of the fixing rod 1265, improves the anti-shake degree of the camera 2. The inner wall of the semi-circular fixed shell 1266 and the lower shell of the camera 2 are tightly fitted and fixed by multiple sets of countersunk screws, and a silicone gasket is placed between them. This silicone gasket can not only buffer the slight vibration generated by the camera 2 itself during operation, preventing the vibration from being transmitted to the adjustment mechanism and affecting stability, but also prevent scratch damage caused by direct contact between the metal shell and the camera 2, thus protecting the camera 2.

[0020] Reference Figure 5-6 As shown in this embodiment: a damping shock absorber 1263 is fixedly installed at the connection between the rotating shaft 1262 and the U-shaped connecting block 126. The damping shock absorber 1263 restricts the swaying of the two sides of the semi-circular fixed shell 1266 and improves the shock resistance of the semi-circular fixed shell 1266 and the camera 2.

[0021] Working principle: A stable installation base is provided by the fixed column 11. The drive motor 12 drives the lead screw 121 to rotate, causing the connecting block 122 to rise and fall along the slide groove 112, adjusting the height of the camera 2. The drive motor 25 drives the connecting plate 1244 to rotate to achieve horizontal turning. At the same time, the slider 1242, the limiting ring 1243 and the connecting rod 1245 in the T-shaped groove 1241 form a conical traction to limit the radial displacement of the connecting plate 1244 to counteract horizontal shaking. The drive motor 31261 drives the rotating shaft 1262 and the semi-circular fixed shell 1266 to rotate to achieve vertical turning of the camera 2. The arc groove 1264 and the fixed rod 1265 cooperate to provide guiding constraints. The damping shock absorber 1263 absorbs vibration, and the silicone pad buffers the vibration of the camera 2 itself. The multi-mechanism cooperation forms a multi-layer anti-shake system, which effectively compensates for the horizontal shaking caused by outdoor lateral wind force, and takes into account multi-angle adjustment and image stability.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
