Description

Technical Field

[0001] This utility model relates to the field of intelligent security technology, and in particular to an intelligent security face recognition device. Background Technology

[0002] In modern society, intelligent security systems are widely used in various scenarios such as communities, office buildings, and transportation hubs. As the core equipment for identity verification and security control, the long-term stability, ease of maintenance, and environmental adaptability of facial recognition devices are of paramount importance.

[0003] Currently, mainstream facial recognition devices on the market mainly suffer from the following technical pain points in terms of installation and maintenance:

[0004] First, installation and disassembly methods are generally inconvenient. Most devices use direct bolt fixing or simple snap-locking structures. While bolt fixing provides a secure connection, disassembly requires specialized tools when the equipment needs maintenance, upgrades, or replacement. This process is cumbersome and time-consuming, and prolonged disassembly and assembly work in crowded public places can create gaps in security monitoring, posing safety hazards. While common snap-locking structures are tool-free, they often suffer from insufficient locking force, loosening after repeated disassembly and assembly, or fatigue damage to the snap-locking components. This makes it difficult to achieve rapid and non-destructive disassembly and assembly cycles while ensuring reliable connections.

[0005] Secondly, there is insufficient automation in perspective adjustment and cleaning / maintenance. Many fixed-installation devices are difficult to adjust, failing to accommodate people of different heights or dynamic tracking needs. Although some high-end models have introduced motor-driven rotation, their rotation structure is usually fixedly connected to the body, without considering linkage design with quick-release functions. More importantly, the devices are exposed to outdoor environments for extended periods, making the lenses highly susceptible to dust, water stains, or dirt, severely impacting recognition accuracy. Existing solutions mostly rely on manual periodic wiping or the addition of separate wipers. The former increases maintenance costs and is inefficient, while the latter has a complex structure and limited cleaning effectiveness (e.g., wiping alone cannot remove fine dust). Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides an intelligent security face recognition device that can combine quick and reliable disassembly and assembly, automated angle adjustment, and efficient self-cleaning functions, thereby improving the equipment's operation and maintenance efficiency, environmental adaptability, and overall reliability.

[0007] The present invention adopts the following technical solution: an intelligent security face recognition device, including a fixed base, and further comprising:

[0008] Rotate the quick-release base to rotate and install it onto the top of the fixed base;

[0009] A face recognition camera has a plug at its bottom, and at least two slots are provided on the periphery of the plug.

[0010] A quick-release connection structure is provided on the rotating quick-release base for releasably fixing the insertion rod; the quick-release connection structure includes a socket provided on the rotating quick-release base, and at least two pins slidably disposed in the socket and corresponding to the slot position, and a return spring is provided between each pin and the inner wall of the socket to drive the pin to pop out in the direction of the insertion rod;

[0011] The periphery of the insertion rod is also provided with the same number of straight slots as the slots, arranged in an alternating pattern.

[0012] When axial pressure is applied to the face recognition camera to disengage the pin from the slot, rotating the plug rod can align the pin with the straight slot, at which point the plug rod can be pulled out axially relative to the socket.

[0013] Preferably, the multiple slots on the insertion rod are arranged in a cross shape.

[0014] Preferably, the top of the fixed base is provided with an annular slide rail, the two sides of the face recognition camera are provided with support rods, and the bottom of the support rod is provided with an arc-shaped slider that slides in cooperation with the annular slide rail.

[0015] Preferably, the annular slide rail has an opening, and the fixed base has a drop groove corresponding to the opening, so that the arc-shaped slider can slide into or out of the drop groove through the opening.

[0016] Preferably, it further includes a drive mechanism, which includes a motor fixed inside the fixed base and a first gear connected to the output shaft of the motor, and a second gear extending into the fixed base and meshing with the first gear is connected to the bottom of the rotating quick-release base.

[0017] Preferably, the device further includes a cleaning component, which includes a bracket fixed to one side of the fixed base and a brush plate mounted on the bracket. The brush plate has a cleaning element on the side facing the lens of the face recognition camera.

[0018] Preferably, the cleaning component includes a fine brush and an air nozzle disposed on the brush plate, and the brush plate is provided with a pipe and an air pipe connector communicating with the air nozzle.

[0019] Preferably, the socket is a cylindrical protrusion formed at the center of the top of the rotating quick-release base, with a slot in the center for inserting the plug.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By setting a plug with a slot and a straight groove at the bottom of the face recognition camera, and cooperating with the quick-release connection structure consisting of a pin and a return spring on the rotating quick-release base, the user only needs to perform three simple operations to complete the disassembly: "press the camera to disengage the pin from the slot - rotate the camera to align the pin with the straight groove - pull out the camera". The installation process is the reverse. The whole process does not require any tools, which simplifies the process of equipment inspection, replacement or upgrade and shortens the maintenance time.

[0022] 2. The arc-shaped slider at the bottom of the support rod and the annular slide rail on the fixed base form a sliding pair, which provides a smooth, low-resistance motion trajectory and lateral support for the rotation of the face recognition camera, enhancing the overall structural rigidity of the equipment in rotation and working states. The design of the opening on the annular slide rail and the corresponding drop groove provides vertical displacement space for the "pressing" action in the quick-release operation, enabling the quick-release function to be smoothly realized on the rotating structure, achieving the organic unity of rotation adjustment and quick disassembly / assembly functions;

[0023] 3. By driving the first gear 11 and the second gear 17 via a motor, the quick-release base rotates, enabling automatic and precise adjustment of the facial recognition camera's shooting angle. This optimizes the recognition range to adapt to different scenarios and automatically rotates the lens to a predetermined position aligned with the cleaning components, laying the foundation for automated maintenance. The fine brush integrated into the brush plate and the air nozzle form a dual cleaning system combining physical cleaning and pneumatic blowing. As the camera rotates, it automatically and effectively cleans the lens surface, thoroughly removing dust, water mist, and other contaminants. This significantly reduces the recognition failure rate caused by lens damage, decreases the frequency of manual cleaning, and improves the long-term reliability and recognition accuracy of the equipment in complex outdoor environments.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Please see Figures 1 to 5 The present invention provides an intelligent security face recognition device, which mainly includes a fixed base 1, a rotating quick-release base 2, a face recognition camera 3, and a quick-release connection structure.

[0033] The fixed base 1 is used for the installation and fixation of the entire device, and a circular groove is provided at the center of its top. The rotating quick-release base 2 is rotatably installed in the circular groove through a bearing or turntable structure, so that the rotating quick-release base 2 can rotate horizontally on the fixed base 1.

[0034] The face recognition camera 3 is the core functional component of the device, and a vertically downward-pointing insertion rod 14 is fixedly connected to its bottom end. In this embodiment, four sets of slots 15 are formed on the periphery of the insertion rod 14, and these four sets of slots 15 are evenly arranged in a cross shape. At the same time, four sets of straight slots 16 are formed in the interval area between two adjacent sets of slots 15, and these four sets of straight slots 16 are arranged in an X shape. The width of the straight slots 16 is slightly larger than the diameter of the pin 12, and the length is sufficient to allow the insertion rod 14 to move axially after unlocking.

[0035] The quick-release connection structure is the core of connecting the face recognition camera 3 and the rotating quick-release base 2. This structure includes a socket, pins 12, and a return spring 13. Specifically, the socket is an integral cylindrical protrusion formed at the center of the top of the rotating quick-release base 2, with a slot in its center matching the shape of the insertion rod 14 for accommodating its insertion. On the inner wall of the slot, corresponding to the positions of the four sets of slots 15 on the insertion rod 14, a set of pins 12 are radially slidably disposed. The inner end of each pin 12 (pointing towards the insertion rod) protrudes from the inner wall of the slot, while the outer end is connected to a return spring 13, the other end of which is fixed inside the socket. In its natural state, the elastic force of the return spring 13 drives the pin 12 to pop out towards the center of the slot.

[0036] The quick-release process is as follows:

[0037] Installation status: When the face recognition camera 3 is installed in place, the plug 14 is fully inserted into the slot of the socket. At this time, the four sets of pins 12, pushed by the return spring 13, are precisely engaged in the corresponding four sets of slots 15 on the plug 14 (e.g., Figure 4 As shown in the figure, the insertion rod 14 is locked in the radial direction, thereby achieving a firm fixation of the face recognition camera 3.

[0038] Disassembly Process: When disassembly is required, first apply an axial pressing force to the face recognition camera 3. This pressure is transmitted through the insert rod 14, forcing the pin 12 to overcome the elastic force of the return spring 13 and retract radially inward, thereby completely disengaging its end from the slot 15. After holding the press or releasing, rotate the face recognition camera 3 (e.g., rotate 45 degrees). At this time, the insert rod 14 rotates accordingly, and the straight slot 16 on it will rotate to a position aligned with the pin 12. Since the straight slot 16 is a through straight groove, after alignment, the pin 12 no longer obstructs the axial movement of the insert rod 14. At this point, the face recognition camera 3, along with the insert rod 14, can be easily pulled upwards, completing the quick disassembly. The installation process is the reverse of the above steps.

[0039] To support and guide the rotation of the face recognition camera 3, support rods 4 are symmetrically fixed on the left and right sides of the camera body. Each support rod 4 has an arc-shaped slider at its bottom end. On the top surface of the fixed base 1, an annular slide rail 8 is provided around the rotating quick-release base 2. The cross-section of the annular slide rail 8 is concave, forming a sliding engagement with the arc-shaped sliders. The design of the support rods 4 and the arc-shaped sliders provides stable and reliable lateral support and a precise circular motion trajectory for the rotation of the face recognition camera 3, preventing it from wobbling.

[0040] Furthermore, to achieve the "pressing" action necessary for quick disassembly, two symmetrical openings are provided on the annular slide rail 8. On the fixed base 1, directly below these two openings, a vertical drop groove 9 is provided on each. When disassembly is required, the face recognition camera 3 is rotated to a specific angle via a drive mechanism, so that the arc-shaped sliders on both sides are precisely aligned with the openings on the annular slide rail 8. At this time, pressing down on the face recognition camera 3 allows the arc-shaped sliders to slide into the drop grooves 9 through the openings, providing sufficient downward displacement space for the face recognition camera 3 and the insertion rod 14, ensuring that the pin 12 can completely disengage from the slot 15.

[0041] The drive mechanism, used to automate the rotation of the face recognition camera 3, includes a motor 10 fixedly installed in the internal cavity of the fixed base 1. A first gear 11 is mounted on the output shaft of the motor 10. A vertical connecting rod is fixedly connected to the bottom center of the rotating quick-release base 2, extending downward into the interior of the fixed base 1, with a second gear 17 mounted at its end. The second gear 17 meshes with the first gear 11. When the motor 10 starts, it drives the second gear 17 to rotate via the first gear 11, thereby causing the rotating quick-release base 2 and all its components (including the face recognition camera 3) to rotate relative to the fixed base 1. This function can be used to adjust the shooting angle or to precisely control the rotation of the face recognition camera 3 to the quick-release position (slider aligned with the opening) or the cleaning position.

[0042] In addition, this device integrates an automatic cleaning component. A bracket 5 is fixed to one side of the fixed base 1, and a brush plate 6 is horizontally extended and fixedly installed at the top of the bracket 5. The position of the brush plate 6 is designed so that when the face recognition camera 3 is rotated to a specific angle under the drive of the motor, the front of its lens is exactly aligned with the brush plate 6. A cleaning component is installed on the side of the brush plate 6 facing the lens. In this embodiment, the cleaning component includes multiple bundles of fine brushes and several air nozzles 18. The brush plate 6 has a cavity and pipeline inside, and an air pipe connector 7 is provided on one side for connecting to an external air source (such as a miniature air pump). The air pipe connector 7 is connected to all the air nozzles 18 through the internal pipeline. During operation, the motor 10 can drive the face recognition camera 3 to the cleaning position, so that the lens slowly moves across the brush plate 6. The fine brushes physically brush the lens surface, while the external air source provides compressed air, which is sprayed onto the lens surface through the air nozzles 18 to blow away the loosened dust and residual water stains, achieving efficient dual cleaning.

[0043] The working principle and process of this utility model are briefly described as follows:

[0044] During normal recognition operation, motor 10 can adjust the shooting angle of face recognition camera 3 according to instructions. When the lens needs cleaning, the controller controls motor 10 to rotate the camera to brush plate 6 for automatic cleaning. When the device needs maintenance or replacement, the controller first controls motor 10 to rotate face recognition camera 3 to the position where the two curved sliders are aligned with the lower groove 9. The operator presses down on face recognition camera 3 to disengage pin 12 from slot 15, then rotates it at a certain angle (e.g., 45 degrees) to align pin 12 with the straight slot 16, and finally pulls it upwards. During installation, the operation is reversed: insert and align the rod 14, then rotate it in the opposite direction. Under the action of return spring 13, pin 12 automatically springs into slot 15 to lock, and finally rotates the camera back to the working position.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
