Description

Technical Field

[0001] This utility model relates to the field of security monitoring and protection technology, and more specifically, to a multimodal security monitoring and protection device. Background Technology

[0002] In the field of modern security monitoring, surveillance cameras are widely used as important security equipment in various scenarios.

[0003] However, existing security monitoring and protection devices still have shortcomings in actual use. On the one hand, the sunshade structure of traditional surveillance cameras is relatively simple, usually using fixed sunshades, which are difficult to adjust flexibly according to different lighting angles and weather conditions. They cannot effectively block sunlight, resulting in problems such as image reflection and overexposure under strong light, affecting the clarity and accuracy of the monitoring image. Utility Model Content

[0004] Based on the aforementioned technical problem that traditional devices use fixed sunshades that cannot be flexibly adjusted according to the angle of light and weather conditions, resulting in a decrease in the quality of the monitoring image, this utility model proposes a multimodal security monitoring and protection device.

[0005] This utility model proposes a multimodal security monitoring and protection device, which includes a first sunshade, a second sunshade, a monitoring camera, a drive shaft, two rotating shafts, and a drive assembly.

[0006] The first sunshade has a sliding cavity on its end face. The end of the second sunshade extends into the sliding cavity and is slidably connected to it. Support frames are fixedly connected to both sides of the monitoring camera. The two ends of the drive shaft pass through the housing of the monitoring camera and are rotatably connected to it. The two ends of the drive shaft are rotatably connected to the support frames. The ends of the rotating shafts are rotatably connected to the corresponding support frames. Swing arms are fixedly connected to the outer walls of the two rotating shafts and the two ends of the drive shaft. Connecting rods are slidably connected to the outer walls of the swing arms. A slider is fixedly connected to the bottom of the connecting rod. The ends of the connecting rods located in the swing arms on the drive shaft are hinged to the first sunshade. The ends of the connecting rods located in the swing arms on the rotating shaft are hinged to the second sunshade. The drive assembly is used to drive the drive shaft and the rotating shaft to rotate in opposite directions.

[0007] Preferably, the outer wall of the swing arm is provided with sliding holes, and the ends of the sliders are slidably connected to the inner walls of the sliding holes.

[0008] Preferably, each connecting rod is fitted with a spring on its outer wall, one end of the spring is fixedly connected to the swing arm, and the other end of the spring is fixedly connected to the slider.

[0009] Preferably, the drive assembly includes a chassis, which is fixedly installed on the outer wall of the surveillance camera. A worm gear is rotatably connected to the inner wall of the chassis. Sector gears are fixedly connected to both ends of the drive shaft and the outer wall of the shaft. Two sector gears located on the same side mesh with each other. A worm wheel is fixedly connected to the end of the drive shaft, and the worm gear meshes with the worm wheel.

[0010] Preferably, the drive assembly further includes a servo motor, which is fixedly connected to the inner wall of the chassis, and the output end of the servo motor is fixedly connected to the worm gear.

[0011] Preferably, the system also includes a bracket, the top of which is fixedly connected to a base, and the base is connected to a rotating frame via a damping shaft. The top of the rotating frame is fixedly connected to the bottom of the surveillance camera.

[0012] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0013] In this device, the drive assembly drives the drive shaft and the rotating shaft to rotate in opposite directions. Through the transmission of components such as the swing arm and connecting rod, the first and second sunshades can be adjusted in angle and extended or retracted. This adjustable sunshade structure can flexibly adjust the position and angle of the sunshades according to the actual lighting conditions, blocking sunlight and avoiding problems such as image reflection and overexposure of the monitoring camera. Compared with traditional fixed sunshades, it improves the clarity and accuracy of the monitoring image. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] like Figures 1-4 As shown, a multimodal security monitoring and protection device includes a first sunshade 17, a second sunshade 18, a monitoring camera 4, a drive shaft 701, two rotating shafts 7, and a drive assembly.

[0021] The first sunshade 17 has a sliding cavity on its end face. The end of the second sunshade 18 extends into the sliding cavity and is slidably connected to it. Both sides of the monitoring camera 4 are fixedly connected to the support frame 6. The two ends of the drive shaft 701 pass through the housing of the monitoring camera 4 and are rotatably connected to it. The two ends of the drive shaft 701 are rotatably connected to the support frame 6. The ends of the rotating shaft 7 are rotatably connected to the corresponding support frame 6. The outer walls of the two rotating shafts 7 and the two ends of the drive shaft 701 are fixedly connected to the swing arms 9. The outer walls of the swing arms 9 are slidably connected to the connecting rods 12. The bottom of the connecting rods 12 is fixedly connected to the slider 11. The ends of the connecting rods 12 located in the swing arms 9 on the drive shaft 701 are hinged to the first sunshade 17. The ends of the connecting rods 12 located in the swing arms 9 on the rotating shaft 7 are hinged to the second sunshade 18.

[0022] The drive assembly drives the drive shaft 701 and the rotating shaft 7 to rotate in opposite directions. The sliding connection design of the first sunshade 17 and the second sunshade 18 allows the sunshade structure to extend and retract, expanding the shading range. The drive shaft 701, rotating shaft 7, swing arm 9, connecting rod 12, and slider 11 form a transmission mechanism, which, in conjunction with the drive assembly, enables angle adjustment of the first sunshade 17 and the second sunshade 18. This structure overcomes the shortcomings of traditional fixed sunshades that cannot be flexibly adjusted, allowing the position and angle of the sunshade to be adjusted according to the angle of sunlight and weather conditions, effectively blocking sunlight and preventing problems such as image reflection and overexposure from the surveillance camera 4, thus improving the clarity and accuracy of the monitoring image.

[0023] In this embodiment, as Figure 4 As shown, the outer wall of the swing arm 9 is provided with sliding holes 10, and the ends of the slider 11 are slidably connected to the inner wall of the sliding holes 10.

[0024] The sliding connection between the sliding hole 10 and the slider 11 provides guidance and limit for the sliding of the connecting rod 12 on the swing arm 9, ensuring that the connecting rod 12 can slide stably during the rotation of the swing arm 9, making the movement of the first sunshade 17 and the second sunshade 18 more stable and accurate, and ensuring the reliability of the sunshade angle adjustment.

[0025] In this embodiment, as Figure 4 As shown, springs 13 are fitted on the outer wall of the connecting rod 12. One end of the spring 13 is fixedly connected to the swing arm 9, and the other end of the spring 13 is fixedly connected to the slider 11.

[0026] When the swing arm 9 rotates and drives the connecting rod 12 to move, the spring 13 plays a buffering role, reducing the impact and vibration during the movement; when the external force is removed, the spring 13 can assist the connecting rod 12 and the slider 11 to return to their original positions.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the drive assembly includes a housing 5, which is fixedly installed on the outer wall of the surveillance camera 4. A worm gear 15 is rotatably connected to the inner wall of the housing 5. Sector gears 8 are fixedly connected to both ends of the drive shaft 701 and the outer wall of the shaft 7. Two sector gears 8 located on the same side mesh with each other. A worm wheel 14 is fixedly connected to the end of the drive shaft 701, and the worm gear 15 meshes with the worm wheel 14.

[0028] The meshing transmission between the worm gear 15 and the worm wheel 14, as well as the meshing transmission between the sector gears 8, can stably transmit the power of the servo motor 16 to the drive shaft 701 and the rotating shaft 7, and realize the opposite rotation of the two.

[0029] In this embodiment, as Figure 3 As shown, the drive assembly also includes a servo motor 16, which is fixedly connected to the inner wall of the housing 5, and the output end of the servo motor 16 is fixedly connected to the worm gear 15.

[0030] By controlling the servo motor 16, the rotation of the worm gear 15 can be controlled, thereby precisely adjusting the rotation of the drive shaft 701 and the rotating shaft 7, so that the sunshade can be quickly and accurately adjusted to the appropriate angle and position according to different lighting conditions.

[0031] In this embodiment, as Figure 1 As shown, the protective device also includes a bracket 1, a base 2 is fixedly connected to the top of the bracket 1, and a rotating frame 3 is connected to the base 2 through a damping shaft. The top of the rotating frame 3 is fixedly connected to the bottom of the monitoring camera 4.

[0032] Operators can manually adjust the angle of the monitoring camera 4 according to actual monitoring needs. After adjustment, the damping shaft can provide a certain amount of resistance to keep the camera position stable.

[0033] Working principle: The output end of the servo motor 16 drives the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 14 at the end of the drive shaft 701, thereby driving the drive shaft 701 to rotate. Since the sector gears 8 at both ends of the drive shaft 701 and the outer wall of the rotating shaft 7 mesh with each other, and the drive assembly drives the drive shaft 701 and the rotating shaft 7 to rotate in opposite directions, the rotating shaft 7 will rotate in the opposite direction when the drive shaft 701 rotates.

[0034] When the drive shaft 701 and the rotating shaft 7 rotate, they drive the swing arm 9 fixed thereon to rotate. During the rotation of the swing arm 9, the slider 11 slides within the sliding hole 10, while the connecting rod 12 slides on the outer wall of the swing arm 9. The connecting rod 12, hinged to the first sunshade 17, drives the first sunshade 17 to move, and the connecting rod 12, hinged to the second sunshade 18, drives the second sunshade 18 to move. Because the end of the second sunshade 18 slides within the sliding cavity of the first sunshade 17, the first sunshade 17 and the second sunshade 18 will adjust their angles and extend / contract according to the rotation of the swing arm 9 to adapt to different light angles and weather conditions.

[0035] During this process, the spring 13 acts as a buffer and reset mechanism, ensuring the stability of the connection and the smoothness of the movement between the connecting rod 12, the slider 11 and the swing arm 9.

[0036] The surveillance camera 4 is connected to the damping shaft of the base 2 via the rotating bracket 3. The angle of the surveillance camera 4 can be manually adjusted according to the actual monitoring needs. After adjustment, the damping shaft can keep the camera position stable.
