Description

Technical Field

[0001] This invention relates to the field of video surveillance technology, specifically to a monitoring device for multi-directional monitoring areas. Background Technology

[0002] In the field of security monitoring, multi-lens monitoring equipment has gradually replaced traditional single-lens equipment as the mainstream choice to achieve both wide field-of-view coverage and precise monitoring of multiple areas. The core components of such equipment typically include a dome for protection and light transmission, a base for mounting support, multiple lens assemblies responsible for image acquisition, and multiple supplementary lighting components for low-light environment auxiliary imaging. The lens assemblies and supplementary lighting components are all assembled in the cavity formed by the dome and the base to ensure component stability and environmental adaptability.

[0003] For example, CN120916046A discloses a multi-lens monitoring device, including a dome, a base, multiple lens assemblies, and multiple supplementary lighting assemblies. The lens assemblies and supplementary lighting assemblies are housed within a cavity formed by the dome and the base. The lens assemblies are circumferentially movable relative to the base, and the supplementary lighting assemblies move synchronously circumferentially during the lens assembly movement. The dome includes a first light-transmitting portion, a second light-transmitting portion, and a light-blocking portion. The light-blocking portion is located between the first and second light-transmitting portions. The first light-transmitting portion is configured to transmit natural light, the second light-transmitting portion is configured to transmit infrared light, and the light-blocking portion is configured to block optical crosstalk between the natural light transmitted by the first light-transmitting portion and the infrared light transmitted by the second light-transmitting portion within the dome. This invention enables both synchronous circumferential movement of the supplementary lighting assemblies and lens assemblies and blocks crosstalk between natural light and infrared light.

A drive shaft 403 is rotatably provided in the middle of the first drive housing 406. The lens body 405 is fixedly mounted on the surface of the drive shaft 403.

[0053] The first drive housing 406 is provided with a pitch adjustment component, and the surface of the first drive housing 406 is provided with a horizontal adjustment component.

[0054] The pitch adjustment assembly includes a transmission gear tube 407, a first transmission belt 408, a transmission gear roller 411, a first bevel gear 412, a second bevel gear 413, and a first drive gear 415. When the first drive gear 415 rotates, the second bevel gear 413 cooperates with the first bevel gear 412 to drive the transmission roller 411, the first transmission belt 408, and the transmission gear tube 407 to transmit power. In turn, the transmission gear tube 407 drives the drive shaft 403 to rotate and adjust the pitch angle of the lens body 405.

[0055] The horizontal adjustment assembly includes a second drive housing 416, a transmission column 417, two transmission wheels 418, a second transmission belt 419 for surface transmission of the transmission wheels 418, and a second drive gear 420. When the second drive gear 420 rotates, it drives the first drive housing 406 to rotate through the transmission column 417 in conjunction with the transmission wheels 418 and the second transmission belt 419. In turn, the first drive housing 406 in conjunction with the drive shaft 403 drives the lens body 405 to rotate horizontally.

[0056] The drive assembly includes a drive frame 501 that is rotatably disposed on the inner wall of the base 1.

[0058] The surface of the first drive disk 502 meshes with the surface of the first drive gear 415;

[0059] The inner wall of the third drive disk 505 meshes with the surface of the second drive gear 420;

[0060] The driving convex strip 504 is placed at both ends of the second driving shell 416 and, driven by the second driving disk 503, drives the lens body 405 to move along the surface of the guide ring 3 through the second driving shell 416 in conjunction with the first driving shell 406.

[0061] A support tube 511 is fixedly installed at the bottom of the inner wall of the base 1, and the drive frame 501 is rotatably connected to the surface of the support tube 511 through a bearing. The drive frame 501 is a regular polygonal tubular structure, and the first drive disk 502, the second drive disk 503 and the third drive disk 505 are respectively movably sleeved on the surface of the drive frame 501.

[0062] The surface of the first drive disk 502 is provided with protrusions and the protrusions are provided with teeth so that the protrusions of the first drive disk 502 mesh with the first drive gear 415, so that the first drive disk 502 does not mesh with multiple first drive gears 415 at the same time.

[0063] There are two drive ridges 504, so that the two drive ridges 504 drive only one second drive housing 416 to revolve.

[0064] The surface of the third drive disk 505 is provided with a hanging part, and the inner wall of the hanging part meshes with the surface of the second drive gear 420, so that the third drive disk 505 does not mesh with multiple second drive gears 420 at the same time.

[0065] A first connecting plate 506 is fixedly installed on the bottom of the surface of the drive frame 501, and a first return spring 507 is fixedly installed between the first drive plate 502 and the first connecting plate 506. A second connecting plate 508 is fixedly installed on the surface of the drive frame 501, and the second connecting plate 508 is located between the second drive plate 503 and the third drive plate 505. A second return spring 509 is fixedly installed between the second drive plate 503 and the second connecting plate 508, and a third return spring 510 is fixedly installed between the third drive plate 505 and the drive frame 501. A drive tube 512 is fixedly installed on the inner wall of the drive frame 501. A drive wheel 513 is engaged with the inner wall of the drive tube 512, and the drive wheel 513 is driven by a servo motor.

[0066] It also includes an adjustment assembly for driving the first drive disk 502, the second drive disk 503 and the drive ridge 504 to move up and down. The adjustment assembly includes a second fixing frame 601 fixedly installed on the top of the guide ring 3. A plurality of first electromagnets 602 are fixedly installed in the middle of the second fixing frame 601. When the first electromagnets 602 are energized, they are like-pairs and repel the third drive disk 505. The third fixing frame 603 is fixedly installed on the inner wall of the guide ring 3. The third fixing frame 603 is located between the second drive disk 503 and the first drive disk 502. When the second electromagnet 604 is connected to the power supply in both positive and negative directions, it is like-pairs and repels the opposite ends of the first drive disk 502 and the drive ridge 504, respectively.

[0067] Both ends of the drive shaft 403 are fixedly mounted with mounting bases 402, which are fixedly mounted on the surface of the first drive housing 406. A lens mounting base 404 is fixedly mounted on the surface of the drive shaft 403, and the lens body 405 is fixedly mounted on the top of the lens mounting base 404. The guide ring 3 is a frame-shaped structure with an opening on the bottom side wall. The transmission gear tube 407 is fixedly mounted on the surface of the drive shaft 403 corresponding to the position of the first drive housing 406. A slot is opened in the middle of the guide ring 3 corresponding to the position of the first drive housing 406. A first fixing bracket 410 is fixedly mounted on the bottom of the first drive housing 406, and a transmission gear roller 411 is rotatably connected to the inner wall of the top of the first fixing bracket 410. A first transmission belt 408 is drively connected to the surfaces of the transmission gear roller 411 and the transmission gear tube 407, and the first transmission belt 408 is located on the inner wall of the first drive housing 406. A partition plate 409 is fixedly mounted in the middle of the inner wall of the first drive housing 406 so that the partition plate 409 can... The first transmission belt 408 is divided in the middle. The first bevel gear 412 is fixedly installed at one end of the transmission toothed roller 411 and rotatably connected to the inner wall of the first fixed frame 410. The surface of the first bevel gear 412 meshes with the top of the second bevel gear 413. A connecting shaft 414 is fixedly installed in the middle of the second bevel gear 413. The connecting shaft 414 passes through and extends to the bottom of the first fixed frame 410 through a bearing. The bottom of the connecting shaft 414 is fixedly installed in the middle of the first drive gear 415. The first drive gear 415 is located at the bottom of the first fixed frame 410. When the first drive disc 502 drives the first drive gear 415 to rotate, the first drive gear 415 drives the second bevel gear 413 to rotate through the connecting shaft 414. The second bevel gear 413 drives the transmission toothed roller 411 to rotate through the first bevel gear 412. In turn, the transmission toothed roller 411 drives the drive shaft 403 to rotate through the first transmission belt 408 and the transmission toothed tube 407.

[0068] In use, the second electromagnet 604 is reversed, causing the same polarity of the second electromagnet 604 and the opposite end of the first drive disk 502 to repel each other. This causes the first drive disk 502 to move downward and press the first return spring 507 until the first drive disk 502 contacts the first drive gear 415. At this time, the drive frame 501 drives the first drive disk 502 to rotate, and the protruding structure of the first drive disk 502 drives the first drive gear 415 to rotate. The first drive gear 415 drives the second bevel gear 413 to rotate through the connecting shaft 414. When the second bevel gear 413 rotates, it will cooperate with the first bevel gear 412 to drive the transmission roller 411 to rotate. The transmission roller 411 drives the first transmission belt 408 to drive, and the first transmission belt 408 drives the drive shaft 403 to rotate through the transmission tooth tube 407. The drive shaft 403 drives the lens body 405 to adjust the pitch angle through the lens mount 404.

[0069] The second drive housing 416 is rotatably connected to the surface of the first drive housing 406 via a bearing. The guide ring 3 has a through groove on its inner sidewall corresponding to the position of the second drive housing 416, so that the second drive housing 416 can move through and extend into the interior of the guide ring 3. The top and one end of the second drive housing 416 corresponding to the position of the inner wall of the second drive housing 416 are respectively fixedly installed with guide frames 421, and the guide frames 421 are tightly fitted to the inner wall of the guide ring 3 so as to guide the revolution of the second drive housing 416 around the guide ring 3.

[0070] In use, the drive frame 501 first drives the second drive disk 503 to rotate, and the two drive protrusions 504 are located directly below the second drive housing 416. At this time, the second electromagnet 604 is connected to the power supply, and the two ends of the second electromagnet 604 and the opposite side of the second drive disk 503 repel each other, thereby causing the second drive disk 503 to move upward and squeeze the second return spring 509. At the same time, the two drive protrusions 504 are located at both ends of the second drive housing 416. At this time, the drive frame 501 cooperates with the second drive disk 503 to drive the drive protrusions 504 to rotate, and the drive protrusions 504 drive the second drive housing 416 to revolve along the surface of the guide ring 3 under the guidance of the guide frame 421. Thus, the second drive housing 416, through the first drive housing 406, cooperates with the locking block 401, the fixing seat 402, the drive shaft 403 and the lens mounting seat 404 to drive the lens body 405 to revolve along the surface of the guide ring 3.

[0071] The second drive housing 416 has a hollow structure in the middle, and the transmission column 417 is rotatably connected to one end of the second drive housing 416 away from the first drive housing 406 through a bearing. Two transmission wheels 418 are respectively fixedly installed on the surfaces of the first drive housing 406 and the transmission column 417, and the second transmission belt 419 is connected to the surfaces of the two transmission wheels 418. The second transmission belt 419 is located on the inner wall of the second drive housing 416, and the second drive gear 420 is fixedly installed on the top of the transmission column 417 and located on the outside of the second drive housing 416.

[0072] In use, when the lens body 405 needs to rotate horizontally, the first electromagnet 602 is energized. The magnetic field polarity generated by the first electromagnet 602 is the same as the polarity of the opposite end face of the third drive disk 505. The resulting repulsive force overcomes the elastic force of the third return spring 510, pushing the third drive disk 505 to slide axially along the drive frame 501 and engage. At this time, the internal gear ring of the lower part of the third drive disk 505 engages with the second drive gear 420. The servo motor-driven drive wheel 513 transmits torque to the third drive disk 505 through the drive tube 512 and the drive frame 501, and then its lower part drives the second drive gear 420 to rotate. The second drive gear 420 drives the first drive housing 406 to rotate relative to the locking block 401 through a synchronous transmission mechanism consisting of the transmission column 417, the transmission wheel 418, and the second transmission belt 419, ultimately realizing the horizontal rotation adjustment of the lens body 405.

[0073] When the horizontal rotation needs to end, the first electromagnet 602 is de-energized, and the electromagnetic repulsion disappears. Under the elastic restoring force of the third return spring 510, the third drive disk 505 is pushed away and disengaged from the second drive gear 420, returning to its original idle position. At this time, although the third drive disk 505 still rotates freely with the drive frame 501, its rotation is no longer transmitted to the lens assembly, the horizontal rotation stops, and the lens body 405 maintains its current horizontal angle.

[0074] Working principle: In use, the invention drives the drive wheel 513 to rotate via a servo motor, which in turn drives the drive tube 512 to rotate, which in turn drives the drive frame 501 to rotate on the surface of the support tube 511. When the drive frame 501 rotates, it will drive the first drive disk 502, the second drive disk 503 and the third drive disk 505 to rotate respectively.

[0075] When the lens body 405 needs to rotate horizontally, the first electromagnet 602 is energized, causing the like poles of the first electromagnet 602 and the third drive disk 505 to repel each other. This causes the third drive disk 505 to move downwards on the surface of the drive frame 501 and compress the third return spring 510 until the third drive disk 505 is placed on top of the fixed base 402 and in contact with it. At this time, the inner wall of the lower hanging part of the third drive disk 505 meshes with the surface of the fixed base 402. As the third drive disk 505 rotates, the lower hanging part of the third drive disk 505 drives the second drive gear 420 to rotate. When the rotation is 0, the fixed base 402 will drive the first drive housing 406 to rotate through the transmission column 417, the transmission wheel 418, and the second transmission belt 419. The first drive housing 406 will drive the lens body 405 to rotate horizontally through the drive shaft 403 and the lens mounting base 404. When the horizontal rotation of the lens body 405 is not required, the first electromagnet 602 will be de-energized. Under the action of the reset and tension of the third reset spring 510, the third drive disk 505 will separate from the second drive gear 420. That is, although the third drive disk 505 still rotates with the drive frame 501, its rotation no longer drives the horizontal rotation of the lens body 405.

[0076] When the lens body 405 needs to revolve horizontally along the surface of the guide ring 3, the drive frame 501 first drives the second drive disk 503 to rotate, causing the two drive protrusions 504 to be positioned directly below the second drive housing 416. At this time, the second electromagnet 604 is connected to the power supply, causing the like poles of the second electromagnet 604 and the opposite end of the second drive disk 503 to repel each other, thereby causing the second drive disk 503 to move upward and compress the second return spring 509. Simultaneously, the two drive protrusions 504 are located at both ends of the second drive housing 416. At this time, the drive frame 501, in conjunction with the second drive disk 503, drives the drive protrusions 504 to rotate, causing the drive protrusions 504 to drive the second drive housing 416. 16 Under the guidance of the guide frame 421, the second drive housing 416 revolves along the surface of the guide ring 3, thereby causing the lens body 405 to revolve along the surface of the guide ring 3 through the first drive housing 406 in conjunction with the locking block 401, the fixing seat 402, the drive shaft 403 and the lens mounting seat 404. When it is not necessary to revolve horizontally along the surface of the guide ring 3, the second electromagnet 604 is de-energized. Under the reset and stretching action of the second reset spring 509, the drive protrusion 504 is separated from the second drive housing 416. That is, although the second drive disc 503 still rotates with the drive frame 501, its rotation no longer drives the lens body 405 to revolve horizontally along the surface of the guide ring 3.

[0077] When the lens body 405 needs to adjust its tilt angle, the second electromagnet 604 is reversed, causing the like poles of the second electromagnet 604 and the opposite end of the first drive disk 502 to repel each other. This causes the first drive disk 502 to move downwards and compress the first return spring 507 until the first drive disk 502 contacts the first drive gear 415. At this time, the drive frame 501 drives the first drive disk 502 to rotate, and the protruding structure of the first drive disk 502 drives the first drive gear 415 to rotate. The first drive gear 415 drives the second bevel gear 413 to rotate through the connecting shaft 414. When the second bevel gear 413 rotates, it engages with the first bevel gear. Wheel 412 drives transmission gear roller 411 to rotate, which in turn drives first transmission belt 408 to rotate. In turn, first transmission belt 408 drives drive shaft 403 to rotate via transmission gear tube 407. Drive shaft 403 drives lens body 405 to adjust pitch angle via lens mounting base 404. When it is not necessary to adjust the pitch angle of lens body 405, second electromagnet 604 is de-energized. Under the action of reset and tension of first reset spring 507, first drive disc 502 and first drive gear 415 are separated. That is, although first drive disc 502 still rotates with drive frame 501, its rotation no longer drives lens body 405 to adjust pitch angle.

[0078] The horizontal rotation adjustment, the revolution adjustment along the direction of the guide ring 3, and the pitch angle adjustment of the lens body 405 all share a single servo motor. This allows a single motor to complete the required angle adjustment of multiple lens bodies 405 in monitoring fields where frequent angle adjustments are not required, thereby solving the problems of complex control circuits and high manufacturing costs.
