Description

Technical Field

[0001] This utility model belongs to the field of industrial control computer equipment manufacturing technology, specifically a magnetic drawer-type battery compartment for industrial control computers. Background Technology

[0002] Industrial PCs, as core equipment in industrial automation control, are widely used in complex environments such as intelligent manufacturing, power monitoring, and rail transportation. They typically have internal battery compartments for installing backup power supplies or real-time clock batteries to ensure the system can retain data or maintain basic operation during power outages. Most existing industrial PC battery compartments employ a built-in structure, with batteries directly soldered or fixed to the motherboard via wires, or using a simple slot-type installation method, along with pluggable terminal blocks for electrical connection.

[0003] As industrial environments demand increasing maintainability and operational stability from equipment, the technical shortcomings of traditional battery compartment structures are becoming increasingly apparent. On one hand, batteries, as consumables, require periodic replacement, but traditional built-in structures are cumbersome to install and remove, often necessitating opening the entire casing and disassembling multiple fasteners, resulting in inconvenient operation and low maintenance efficiency. On the other hand, battery interfaces typically use ordinary plug-in terminals, which are prone to contact wear or poor contact during repeated insertion and removal, and lack effective anti-reverse insertion design, posing a short-circuit risk. Furthermore, the harsh vibration environment of industrial environments, coupled with the lack of effective limiting structures in traditional battery compartments, can lead to loose connections or battery displacement after prolonged operation, resulting in power outages or data loss, severely impacting the reliability and safety of industrial control computers.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example:

[0028] A magnetic drawer-type battery compartment for industrial control computers, such as Figure 1 As shown, it is installed inside the outer casing 1 of the industrial control computer, such as Figure 2 as well as Figure 3 As shown, a partition 4 and a main board 3 are provided inside the outer casing 1. The partition 4 is located below the main board 3, as shown. Figure 4 As shown, the battery compartment 2 is located between the partition 4 and the bottom plate of the outer casing 1; the battery compartment 2 includes a movable compartment 5 and a mounting base 6. The mounting base 6 is fixed to the bottom plate of the outer casing 1 by bolts or adhesive. The mounting base 6 has flanges on both sides, and a support plate 13 is fixed to the mounting base 6. Figure 5 As shown, the support plate 13 has an L-shaped structure and is symmetrically arranged on the mounting base 6. A groove 14 is formed between the support plate 13, the flanges on both sides of the mounting base 6, and the partition plate 4. The movable compartment 5 is movably connected to the groove 14. Figure 6 As shown, the active compartment 5 includes a compartment body 18 and a mounting plate 16. The compartment body 18 is used to store batteries. The mounting plate 16 is bolted to the front side of the compartment body 18. Fastening heads 17 are provided on both sides of the mounting plate 16, and the fastening heads 17 are used to connect to the outer casing 1. A first circuit board 15 is fixed to the rear side of the compartment body 18. A magnetic female connector 7 is provided on the first circuit board 15. The magnetic female connector 7 is connected to the battery through a cable. A second circuit board 9 and a battery management board 12 are also fixed to the partition 4. A magnetic male connector 8 is provided on the second circuit board 9. The magnetic male connector 8 and the magnetic female connector 7 cooperate with each other. The magnetic male connector 8 is electrically connected to the battery management board 12.

[0029] It should be noted that the first circuit board can use an industrial-grade battery-side data acquisition adapter PCB board, similar to the voltage sampling adapter board built into the backup battery in existing industrial control systems. The magnetic female connector uses an industrial-grade foolproof magnetic connector. The second circuit board uses a standardized industrial adapter board, compatible with Molex and TE industrial connectors. The magnetic male connector uses a foolproof magnetic connector that matches the magnetic female connector. The battery management board uses an industrial-grade lithium battery BMS module, such as a customized BMS board based on an STM32G431 industrial-grade MCU. It includes at least a main control MCU, charging / discharging MOSFETs, fuses, voltage acquisition circuit, current sampling circuit, temperature sampling circuit, CAN bus, UART, RS485, overcharge protection, over-discharge protection, overcurrent protection, and short-circuit hardware protection. During use, the second circuit board acquires real-time battery voltage data from the first circuit board, calculates the battery SOC and SOH, executes charging / discharging logic control, and immediately cuts off the battery output when overvoltage / undervoltage / overcurrent is detected, protecting the industrial control computer and the battery.

[0030] The outer casing 1 serves as the overall frame of the industrial control computer, housing and protecting the internal components; the mainboard 3 is the core circuit board of the industrial control computer. The mounting base 6 is fixed to the bottom plate of the outer casing 1, and its two flanges form part of the sliding groove 14; the support plate 13, with an L-shaped structure, is symmetrically fixed to the mounting base 6, forming the sliding groove 14 together with the flanges and partition 4, providing precise sliding guidance for the movable compartment 5. The movable compartment 5 includes a compartment body 18 and a mounting plate 16. The compartment body 18 stores the battery, and the mounting plate 16 is bolted to the front of the compartment body 18. Fastening heads 17 on both sides are used to lock it to the outer casing 1, preventing the movable compartment 5 from loosening. A first circuit board 15 is fixed to the rear of the compartment body 18, and a magnetic female connector 7 is provided on the board. This connector is connected to the battery via a cable; a second circuit board 9 and a battery management board 12 are fixed to the partition 4. The second circuit board 9 has a magnetic male connector 8, which magnetically engages with the magnetic female connector 7 and is electrically connected to the battery management board 12, thereby achieving electrical conduction between the battery and the battery management board 12.

[0031] In use, the movable compartment 5 is pushed into the outer casing 1 via the slide groove 14. When pushed to the working position, the magnetic female connector 7 on the first circuit board 15 on the rear side of the compartment 18 and the magnetic male connector 8 on the second circuit board 9 on the partition 4 automatically magnetically align and make tight contact, completing the electrical connection between the battery and the battery management board 12. At the same time, the fastening heads 17 on both sides of the mounting plate 16 are connected to the outer casing 1, locking the movable compartment 5 in place to ensure that it will not shift due to vibration during operation. When the battery needs to be replaced, simply release the fastening heads 17 and pull the movable compartment 5 outward; the magnetic connector will automatically separate, and the battery can be easily removed.

[0032] This design employs a drawer-type structure, greatly facilitating battery maintenance and replacement without disassembling the entire unit. The magnetic connector enables blind-plug connection, ensuring simple operation and reliable contact, reducing the risk of damage during insertion and removal. The slide 14 consists of a flange, an L-shaped support plate 13, and a partition 4, providing high guiding accuracy and a stable structure. The fastening head 17 ensures reliable locking of the movable compartment 5 during operation, preventing loosening due to vibration. The battery management board 12 is independently mounted on the partition 4, facilitating precise battery management and improving the overall maintainability and safety of the industrial control computer.

[0033] In a preferred embodiment, the magnetic female connector 7 and the magnetic male connector 8 are magnetic connectors with a foolproof structure; the foolproof structure includes a guide groove and a guide protrusion; the guide groove is disposed in the magnetic female connector 7, and the guide protrusion is disposed in the magnetic male connector 8; or, the guide groove is disposed in the magnetic male connector 8, and the guide protrusion is disposed in the magnetic female connector 7.

[0034] In this preferred embodiment, the foolproof structure, through the cooperation of the guide groove and the guide protrusion, ensures that the magnetic male and female connectors can only be aligned and attracted in the only correct direction, effectively preventing short circuits, contact damage, or poor contact caused by reverse or misaligned insertion; at the same time, it plays a physical guiding role in blind insertion operations, improving the smoothness of insertion and removal and the reliability of connection.

[0035] In a preferred embodiment, the magnetic female connector 7 has a recessed structure with the contact point located in the groove; the magnetic male connector 8 has a protruding structure with the contact point located on the protruding surface; the magnetic male connector 8 and the magnetic female connector 7 are in contact when they are magnetically engaged.

[0036] This preferred embodiment employs a recessed female connector and a protruding male connector design, concealing the contacts within the female connector's groove. This effectively prevents accidental short circuits caused by fingers or foreign metal objects, enhancing operational safety. Furthermore, the engagement of the protrusion and groove guides alignment during magnetic attraction, ensuring precise contact and reliable electrical connection.

[0037] In a preferred embodiment, the first circuit board 15 also integrates a battery voltage detection circuit. The battery voltage detection circuit is connected to the battery via a cable and transmits the detected voltage signal to the magnetic male connector 8 via the magnetic female connector 7, and then to the battery management board 12.

[0038] This preferred embodiment integrates a battery voltage detection circuit (e.g., a high-precision voltage divider resistor and an RC filter circuit) on the first circuit board 15 to achieve real-time monitoring of the battery voltage. The detected voltage signal is reliably transmitted to the battery management board 12 via a magnetic connector, enabling the battery management board 12 to perform charge and discharge control, power calculation, and low power warning based on accurate voltage data, thereby improving battery safety.

[0039] In a preferred embodiment, such as Figure 2 as well as Figure 3 As shown, a signal socket 10 is provided on the second circuit board 9. The signal socket 10 is electrically connected to the battery management board 12, and the battery management board 12 is electrically connected to the main board 3.

[0040] This preferred embodiment uses a signal socket 10 to achieve electrical connection between the battery management board 12 and the main board 3, enabling battery status information (such as voltage, power level, and alarm signals) to be uploaded to the main board 3 in real time. Simultaneously, it receives control commands (such as low battery shutdown) from the main board 3, thereby achieving system-level power collaborative management and intelligent protection. The signal socket 10 can use an industrial-grade PH2.0 / XH2.54 terminal block or an RS485 / CAN bus socket.

[0041] In a preferred embodiment, the fastening head 17 of the mounting plate 16 is a bolt structure, and a corresponding locking hole is provided on the side wall of the outer shell 1. When the movable chamber 5 is pushed into place, the fastening head 17 is screwed into the locking hole to lock the movable chamber 5.

[0042] This preferred embodiment uses a locking method that combines bolts and locking holes, so that after the movable chamber 5 is pushed into place, it can be mechanically locked by screwing in the bolts, which effectively prevents loosening due to vibration or impact. At the same time, it is easy to unscrew and unlock during disassembly and maintenance, improving connection reliability and operational convenience.

[0043] In a preferred embodiment, such as Figure 4 As shown, a remote control board 11 is also fixedly connected to the partition 4, and the remote control board 11 is connected to the battery management board 12.

[0044] It should be noted that the remote control board includes at least an industrial DTU module and an industrial control remote management sub-board, such as a remote communication board with an STM32+W5500 Ethernet chip. This board reads battery voltage, power, and fault status from the battery management board via the UART / CAN interface and uploads the data to the SCADA operation and maintenance platform and cloud platform via Ethernet / 4G. It also receives instructions from the remote backend (such as remotely cutting off battery output or remotely triggering the industrial control machine to shut down) and forwards them to the battery management board for execution.

[0045] This preferred embodiment adds a remote control board 11 and connects it to the battery management board 12 to realize remote monitoring and uploading of battery status information (such as power and voltage). It also supports remote execution of management commands such as low power shutdown, thereby improving the intelligence and convenience of system operation and maintenance.

[0046] In a preferred embodiment, the support plate 13 and the mounting base 6 are integrally formed or are separate welded structures.

[0047] This preferred embodiment achieves a reliable connection between the support plate 13 and the mounting base 6 through integral molding or separate welding. The former can reduce the number of parts, improve assembly efficiency and structural integrity, while the latter facilitates processing and adjustment and reduces costs. Both methods can enhance the stability of the mounting base 6.

[0048] In a preferred embodiment, wear-resistant lining strips are fitted onto the inner sides of the flanges on both sides of the mounting base 6 and the sliding contact surface of the support plate 13. The wear-resistant lining strips are made of polytetrafluoroethylene and are used to reduce the frictional resistance when the movable compartment 5 is pulled out, while preventing wear on the sliding groove.

[0049] In a preferred embodiment, the magnetic attraction force of the magnetic female connector 7 and the magnetic male connector 8 ranges from 8 to 15 N. This design ensures the stability of the connection after they are fitted together, while also allowing for easy separation when the movable compartment 5 is manually pulled out, thus avoiding damage to the connector contacts.
