[0001] This utility model relates to the field of video surveillance and storage technology, specifically to an intelligent video recorder. Background Technology

[0002] Intelligent video recorders are core devices in video surveillance systems, widely used in shops, office buildings, data centers, and other scenarios. However, most existing intelligent video recorders suffer from the following drawbacks: First, their chassis design is incompatible with standard server racks, requiring separate mounting brackets, which are space-consuming and cumbersome to install. Second, the number of PoE power supply circuits and storage hard drive bays are separate, necessitating additional PoE switches or external storage devices, resulting in low integration and complex wiring. Third, hard drive installation and maintenance are inconvenient; traditional hard drive brackets often use fixed bolt connections, requiring individual screw loosening during disassembly, which is time-consuming and labor-intensive. Fourth, power supply stability is insufficient; a single power supply failure can easily cause the entire device to shut down, affecting the continuity of monitoring.

[0003] Therefore, there is an urgent need in this field for an intelligent video recorder that is compatible with standard server racks, integrates PoE power supply and large-capacity storage, and offers convenient hard drive maintenance. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an intelligent video recorder that achieves efficient compatibility with server racks, enhances equipment integration, simplifies hard drive maintenance, and improves power supply stability.

[0009] Furthermore, the cooling fan speed is controlled by the motherboard: the fan speed increases when the internal temperature reaches a preset temperature rise threshold and decreases when it reaches a preset temperature drop threshold; when the preset safety critical temperature threshold is reached, overheat protection is triggered, the fan runs at full speed and the power supply to non-core components is cut off.

[0010] Furthermore, the first DC output switching power supply is adapted to the power supply requirements of the LED indicator board, cooling fan and hard drive, and supplies power to the above components; the second DC output switching power supply is adapted to the power supply requirements of the 16-channel PoE interface board, and supplies power to it.

[0011] Furthermore, the motherboard integrates a video encoding chip that supports processing multiple channels at different resolutions, and an intelligent analysis chip with motion detection and human recognition functions; the POE interface board and LED indicator board are electrically connected to the motherboard via ribbon cables, and the three are arranged in parallel in the middle area inside the bottom shell.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model discloses an intelligent video recorder, which achieves the design goals of being adaptable to server racks, highly integrated, easy to maintain, stable and secure through a 1U standard chassis, dual power supply with hierarchical power supply, integration of 16-channel PoE and 4 hard drive bays, and quick-release hard drive bracket design.

[0021] like Figures 1 to 3 As shown, an intelligent video recorder includes a cabinet mounting ear 1, an upper cover 2, a PCBA_LED indicator board 3, a bottom shell 4, a cooling fan 5, a PCBA_main board 6, a PCBA_POE interface board 7, an AC power interface 8, a power switch 9, a second DC output switching power supply 10, a first DC output switching power supply 11, a hard disk 12, and a hard disk bracket 13.

[0022] The casing of this intelligent video recorder adopts a standard 1U server rack chassis design, with the core components including a bottom shell 4, an upper cover 2, and rack mounting ears 1. The rack mounting ears 1 are made of galvanized steel plate with pre-set installation strength, and there are two in total. They are symmetrically fixed to the two side walls of the bottom shell 4 with screws. The rack mounting ears 1 have oblong mounting holes adapted to standard server rack bolts to support the device's forward and backward adjustment within the rack. Both the upper cover 2 and the bottom shell 4 are detachably connected using clips or screws. The surface of the upper cover 2 has ventilation holes adapted to the heat dissipation module, and a rectangular transparent PC material viewing window is reserved in the area corresponding to the PCBA_LED indicator board 3 for observing the display status of various working status indicators such as power, recording, and PoE power supply.

[0023] Furthermore, the dual power supply module provides stable and independent hierarchical power supply for the equipment. It consists of a first DC output switching power supply 11 and a second DC output switching power supply 10, which are fixed side-by-side inside the bottom shell near the AC power interface 8. Both are equipped with shock-absorbing rubber pads on the bottom to reduce vibration transmission during equipment operation and avoid affecting the stability of the power supply module. After the module is connected to the AC power interface 8, it is divided into two independent power supply circuits: the second DC output switching power supply 10 supplies power to the PCBA_POE interface board 7 of the intelligent core circuit module, with its output power precisely adapted to the power requirements of 16 POE interfaces operating simultaneously; the first DC output switching power supply 11 provides centralized power to the PCBA_motherboard 6, PCBA_LED indicator board 3, cooling fan 5, and hard drive 12, with its output power matched to the rated power consumption of each component to ensure sufficient and stable power supply. Both power supply lines are encased in insulating protective sleeves and are physically isolated during wiring to effectively avoid electromagnetic interference and improve power supply reliability.

[0024] Furthermore, the intelligent core circuit module is the core of the device to realize video processing, PoE power supply and status feedback functions, including PCBA_main board 6, 16-channel PCBA_POE interface board 7 and PCBA_LED indicator board 3. PCBA_main board 6 is fixed to the middle area inside the bottom shell 4 by four insulating support pillars of the same height. The height design of the support pillars allows for a uniform heat dissipation gap between PCBA_main board 6 and bottom shell 4. PCBA_main board 6 integrates a video encoding chip that supports multi-channel video processing at different resolutions and an intelligent analysis chip with motion detection and human recognition functions. PCBA_POE interface board 7 achieves precise docking with PCBA_main board 6 through onboard pin headers. After docking, both are fixed to the inner wall of bottom shell 4 with Phillips head screws. The 16 network ports on PCBA_POE interface board 7 are arranged in an array, each network port The positions of all the LEDs correspond one-to-one with the openings on the side wall of the bottom shell 4, ensuring that the network cable connection is not obstructed. The PCBA_LED indicator board 3 is connected to the PCBA_main board 6 via terminal wires. The plugs of the terminal wires are designed with anti-reverse insertion protrusions to avoid wiring errors. The surface-mount LEDs on the PCBA_LED indicator board 3 are divided into different types such as power lights, recording lights, POE status lights and alarm lights, and are distinguished by different colors. Their installation orientation is directly opposite the transparent observation window of the upper cover 2. The three are arranged in a parallel state in the middle area inside the bottom shell. The wiring is neatly organized through the wiring grooves on the edge of the PCBA_main board 6 to avoid messy wiring affecting heat dissipation.

[0025] Furthermore, the video storage module is responsible for storing and quickly maintaining large-capacity video data, and consists of a quick-release hard drive bracket 13 and four hard drives 12. The hard drive bracket 13 features a quick-release design, allowing for easy assembly and disassembly from the bottom shell 4 without additional tools. The hard drive bracket 13 has four independent slots inside, precisely sized to fit the hard drives 12. Each slot's inner wall is lined with a uniformly thick silicone rubber cushioning pad, effectively reducing the impact of vibration on the hard drive heads and protecting data storage security. Two cylindrical positioning pins are located on each side edge of the hard drive bracket 13, integrally formed with it. Corresponding positioning holes are provided on the bottom shell 4; inserting the positioning pins into these holes allows for quick positioning of the hard drive bracket 13 and the bottom shell 4. Repeated calibration is required; each slot on the top of the hard drive bracket 13 has a spring steel elastic pressure plate. When the four hard drives 12 are installed side by side in the slots, the elastic pressure plate will automatically fit against the top surface of the hard drive 12 to form a flexible clamping force, which restricts the hard drive 12 from moving up and down during operation, further improving installation stability; the hard drive 12 is electrically connected to the corresponding interface of the PCBA_motherboard 6 through a serial advanced technology accessory data cable with anti-pull design, which supports real-time writing of video data and fast query of historical data. The connection interface has a snap-on fixing structure to prevent the data cable from falling off.

[0026] Furthermore, the heat dissipation module is used to quickly dissipate the heat generated inside the equipment, ensuring stable operation of each component at a suitable temperature. Its core consists of two cooling fans 5. Both cooling fans 5 are fixed to the same end of the inner sidewall of the bottom shell 4 using screws with shock-absorbing pads, and are located on the same side of the PCBA_main board 6. The installation height of the cooling fans 5 is aligned with the heat dissipation gap of the PCBA_main board 6, and the airflow direction is towards the other end of the length of the bottom shell 4, forming an airflow channel with the array of heat dissipation holes of the upper cover 2. The cooling fans 5 are electrically connected to the PCBA_main board 6 and are powered by the first DC output switching power supply 11, while also receiving power from the PCBA_main board 6. The intelligent speed control of board 6 involves a temperature sensor on the PCBA_motherboard 6 collecting real-time internal ambient temperature data. When the temperature reaches a preset temperature rise threshold, PCBA_motherboard 6 controls the cooling fan 5 to increase its speed via pulse width modulation signal, enhancing heat dissipation efficiency. When the temperature drops to a preset cooling threshold, the speed decreases accordingly, reducing energy consumption and noise. If the temperature reaches a preset safety critical temperature threshold, the system immediately triggers an overheat protection mechanism, the cooling fan 5 switches to full-speed operation, and simultaneously cuts off power to non-core components such as hard drive 12, leaving only the core circuitry of PCBA_motherboard 6 to operate, thus preventing irreversible damage to the equipment caused by high temperatures.

[0027] Furthermore, the AC power interface 8 and the power switch 9, as the power input control components of the device, are fixed to the same side wall of the bottom shell 4, resulting in a compact layout and ease of operation. The AC power interface 8 is fitted with a flip-type anti-accidental contact protective cover, which is connected to the interface seat via a hinge structure. It can be opened and closed without disassembly, preventing short circuits caused by foreign objects touching the interface without affecting the insertion and removal of the power plug. The power switch 9 is a rocker switch with a clear tactile feel, its operating end exposed at the opening on the side wall of the bottom shell 4. The surface of the power switch 9 has anti-slip textures, improving the convenience and stability of the pressing operation.

[0028] In summary, this intelligent video recorder features 1U standard rack mounting, dual power supply with tiered power delivery, 16-channel PoE and 4 hard drive bays, quick-release hard drive brackets, and intelligent heat dissipation. It boasts advantages such as high integration, good rack adaptability, convenient maintenance, and stable and secure operation, making it suitable for video data storage and management in various video surveillance scenarios.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
