Description

Technical Field

[0001] The utility model relates to the technical field of security monitoring, in particular to a multi-sensor security monitoring terminal device which is convenient to install. Background Technique

[0002] A multi-sensor security monitoring terminal is an intelligent security device integrating a variety of detection technologies. It usually integrates a variety of sensors such as a high-definition camera, infrared thermal imaging, sound collection, motion detection, access control, and even environmental sensors (such as smoke and gas alarms). Through artificial intelligence algorithms, it comprehensively analyzes multi-source information to achieve all-weather, all-round, and intelligent security protection of the monitored area. It can not only record videos and audios in real time, but also accurately identify threats such as abnormal intrusion, fire, and leakage, and immediately trigger linkage measures such as audible and visual alarms and remote push notifications, greatly improving the reliability, accuracy, and active warning ability of the security system.

[0003] For the multi-sensor security monitoring cameras in the prior art, whether using adjustable or fixed mounting brackets, the core problem is that the optical center point of the camera (i.e., the physical position of the lens) is fixed after installation. Although many cameras have pan-tilt or electronic pan-tilt functions and can rotate horizontally and vertically, this movement is essentially a perspective scan centered on the fixed optical center point. This results in its inability to change the spatial position relationship between the camera and the photographed scene, and thus unable to generate parallax. In practical applications, when multiple targets (such as people) are on the same radial path in front of the lens, due to the single perspective, the foreground target will completely block the background target, forming a shooting blind area. This inherent physical limitation makes it difficult for traditional installation methods to cope with occlusion problems in complex scenarios and restricts the full play of monitoring efficiency.

[0004] Therefore, we propose a multi-sensor security monitoring terminal device which is convenient to install. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a multi-sensor security monitoring terminal device which is convenient to install.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a multi-sensor security monitoring terminal device which is convenient to install, including a multi-sensor camera body, one side of the multi-sensor camera body is provided with a mounting support, both inner walls of the mounting support are jointly and slidably connected with a sliding seat, the inner bottom of the sliding seat is fixedly connected with a motor with a brake, and a synchronous transmission component is jointly installed between the driving end of the motor with a brake and the sliding seat;

[0007] A rack and pinion lifting assembly is installed between the synchronous transmission assembly and the mounting support.

[0008] A sleeve is fixedly connected to one end of the slide block, and a screw-type telescopic rod is installed together with the sleeve and the synchronous transmission assembly. A mounting base is fixedly connected to the movable end of the screw-type telescopic rod.

[0009] A bidirectional moving component is installed on the inner top of the assembly base. Both movable ends of the bidirectional moving component are fixedly connected to buckles. The two buckles are fastened together to a locking seat, which is inserted into the bottom of the assembly base and fixedly connected to the multi-sensor camera body.

[0010] Furthermore, slide rails are fixedly connected to both inner walls of the mounting bracket, and the slide rails are slidably connected to the slide block. This structure provides guidance for the lifting and lowering movement of the slide block, effectively preventing shaking, deflection or jamming that may occur during the lifting and lowering process.

[0011] Furthermore, the synchronous transmission assembly includes a first bevel gear, which is fixedly connected to the drive shaft of the brake motor. A second bevel gear is meshed with the outer surface of the first bevel gear, and a rotating shaft is fixedly connected to the inner surface of the second bevel gear. The bevel gear transmission structure ingeniously converts the vertical rotational motion of the drive shaft of the brake motor into the horizontal rotational motion of the rotating shaft, realizing a 90-degree change in the power transmission direction.

[0012] Furthermore, the rack and pinion lifting assembly includes a gear, which is disposed on one side of the slide. The mounting shaft of the gear passes through the slide and is rotatably connected to the slide. The rotating shaft is fixedly connected to the gear. The outer surface of the gear is meshed with the rack body, and the rack body is fixedly connected to the mounting support. The gear and rack body cooperate to linearly convert the rotational motion of the rotating shaft into the vertical lifting motion of the slide, with a constant transmission ratio.

[0013] Furthermore, the screw-type telescopic rod includes a one-way screw, which is rotatably connected to the sleeve and fixedly connected to the rotating shaft. The outer surface of the one-way screw is threaded with a movable rod, which is slidably connected to the sleeve and fixedly connected to the mounting base. The one-way screw converts the rotational motion of the rotating shaft into the linear telescopic motion of the movable rod. Utilizing the self-locking characteristic of the thread, reliable locking can be achieved at any telescopic position.

[0014] Furthermore, the bidirectional moving component includes a handwheel, which is disposed on one side of the mounting base. A bidirectional screw is fixedly connected to one side of the outer surface of the handwheel, and the bidirectional screw passes through the mounting base and is rotatably connected to the mounting base. Two sliders are symmetrically threaded on the outer surface of the bidirectional screw, and the sliders slide against the inner wall of the mounting base and are fixedly connected to the buckle plate. The bidirectional screw ensures the synchronicity of the movement of the sliders on both sides and the balance of the applied force.

[0015] Furthermore, locking grooves are provided on both outer walls of the locking seat, and the locking grooves match the buckle plate. The matching design of the locking grooves and buckle plates constitutes an efficient and quick clamping interface. After the buckle plate is embedded in the locking groove, a reliable mechanical interlock is formed.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model uses a synchronous transmission component driven by a brake motor to simultaneously drive the rack and pinion lifting component to vertically raise and lower the slide along the mounting support, and to drive the screw telescopic rod to horizontally extend and retract the mounting base. This achieves two-dimensional linkage adjustment of the spatial position of the camera's optical center point, fundamentally changing the relative positional relationship between the camera and the monitored scene. It can produce a significant parallax effect, effectively solving the problem of blind spots caused by the foreground obscuring the background in traditional fixed installation methods, and significantly improving the monitoring coverage and target recognition capabilities in complex scenes.

[0018] 2. In use, this utility model drives the bidirectional screw of the bidirectional moving component to rotate by rotating the handwheel, forcing the two sliders to move the buckle plates towards or away from each other, thereby enabling them to quickly engage or disengage from the locking groove on the locking seat. Combined with the insertion and limiting structure of the locking seat and the mounting base, it realizes one-step quick assembly, disassembly and locking between the multi-sensor camera body and the mounting bracket without any tools, greatly simplifying the installation, debugging and subsequent maintenance and replacement process, and improving work efficiency.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, a multi-sensor security monitoring terminal device that is easy to install is disclosed. The device includes a multi-sensor camera body 1, which integrates a high-definition visible light camera, an infrared thermal imaging module, a microphone, a temperature and humidity sensor, and other sensors into a smart camera. A mounting bracket 6 is provided on one side of the multi-sensor camera body 1. Slide seats 4 are slidably connected to the inner walls of both sides of the mounting bracket 6. Slide rails 7 are fixedly connected to the inner walls of both sides of the mounting bracket 6, and slide rails 7 are slidably connected to slide seats 4. Multiple mounting holes are evenly provided on the mounting bracket 6 to facilitate installation.

[0028] A brake motor 20 is fixedly connected to the inner bottom of the slide 4. A synchronous transmission assembly is installed between the drive end of the brake motor 20 and the slide 4. The synchronous transmission assembly includes a first bevel gear 18, which is fixedly connected to the drive shaft of the brake motor 20. A second bevel gear 17 is meshed with the outer surface of the first bevel gear 18. A rotating shaft 16 is fixedly connected to the inner surface of the second bevel gear 17. The model of the brake motor 20 is GYC751DC1-SE, which has a braking self-locking effect.

[0029] A rack and pinion lifting assembly is installed between the synchronous transmission assembly and the mounting support 6. The rack and pinion lifting assembly includes a gear 19, which is located on one side of the slide 4. The mounting shaft of the gear 19 passes through the slide 4 and is rotatably connected to the slide 4. The rotating shaft 16 is fixedly connected to the gear 19. The outer surface of the gear 19 is meshed with the rack body 5, which is fixedly connected to the mounting support 6. Both the gear 19 and the rack body 5 are made of medium carbon steel or alloy steel and are heat-treated to ensure the hardness and wear resistance of the tooth surface.

[0030] One end of the slide block 4 is fixedly connected to a sleeve 3. The sleeve 3 and the synchronous transmission assembly are jointly equipped with a screw-type telescopic rod. The movable end of the screw-type telescopic rod is fixedly connected to an assembly seat 2. The screw-type telescopic rod includes a one-way screw 8, which is rotatably connected to the sleeve 3 and fixedly connected to the rotating shaft 16. The outer surface of the one-way screw 8 is threaded with a movable rod 9, which is slidably connected to the sleeve 3 and fixedly connected to the assembly seat 2. The thread helix angle of the one-way screw 8 is smaller than the friction angle, which gives the one-way screw 8 a self-locking capability, preventing it from shifting due to vibration or load.

[0031] A bidirectional moving assembly is installed on the inner top of the mounting base 2. Both movable ends of the bidirectional moving assembly are fixedly connected to a buckle plate 13. The bidirectional moving assembly includes a handwheel 10, which is located on one side of the mounting base 2. A bidirectional screw 11 is fixedly connected to one side of the outer surface of the handwheel 10. The bidirectional screw 11 passes through the mounting base 2 and is rotatably connected to the mounting base 2. Two sliders 15 are symmetrically threaded on the outer surface of the bidirectional screw 11. The sliders 15 slide against the inner wall of the mounting base 2 and are fixedly connected to the buckle plate 13. The thread helix angle of the bidirectional screw 11 is smaller than the friction angle, which gives the bidirectional screw 11 a self-locking capability, preventing it from shifting due to vibration or load.

[0032] The two buckle plates 13 are fastened together with the locking seat 14, and the locking seat 14 is inserted into the bottom of the mounting base 2 and fixedly connected to the multi-sensor camera body 1. The outer walls on both sides of the locking seat 14 are provided with locking grooves 12, and the locking grooves 12 match the buckle plates 13.

[0033] The braked motor 20 is connected to the built-in controller of the multi-sensor camera body 1 by wires, which facilitates the control of the braked motor 20. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in combination with common knowledge.

[0034] Working principle: When installing the multi-sensor camera body 1, first insert the locking seat 14 into the bottom opening of the mounting base 2, and then rotate the handwheel 10 to drive the bidirectional screw 11 to rotate. When the bidirectional screw 11 rotates, the two sliders 15 move towards each other. Since the sliders 15 are fixedly connected to the buckle plate 13, the buckle plate 13 moves accordingly. When the two buckle plates 13 move towards each other, they will engage with the locking groove 12 of the locking seat 14, thereby locking the camera body 1.

[0035] When disassembling the multi-sensor camera body 1, turn the handwheel 10 in the opposite direction to move the buckle 13 away from the locking groove 12. Once the buckle 13 is disengaged from the locking groove 12, the locking seat 14 can be released, making it easier to disassemble the multi-sensor camera body 1.

[0036] When it is necessary to adjust the position of the multi-sensor camera body 1, the braked motor 20 fixed to the bottom of the slide 4 is activated. The drive shaft of the braked motor 20 drives the first bevel gear 18 to rotate. The first bevel gear 18 meshes with the second bevel gear 17, transmitting power to the rotating shaft 16 fixed to the second bevel gear 17. One end of the rotating shaft 16 drives the gear 19 to rotate. The gear 19 engages with the rack body 5, driving the slide 4 to rise along the slide rail 7.

[0037] At the same time, the other end of the rotating shaft 16 drives the one-way screw 8 to rotate. When the one-way screw 8 rotates, the movable rod 9, which is connected to it by a thread, cannot rotate due to the restriction of the sleeve 3. It can only move horizontally in a straight line along the sleeve 3 under the drive of the thread, thereby pushing the end mounting seat 2 to extend. Then, it drives the multi-sensor camera body 1 to move through the locking seat 14. This allows the multi-sensor camera body 1 to change its horizontal observation distance while changing its height, which greatly expands the adjustable field of view and is the key to generating effective parallax and solving the occlusion problem.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
