Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a desktop computer power supply device that integrates a backup battery into the display stand. Background Technology

[0002] Currently, desktop computers generally lack built-in backup power systems, resulting in the following problems: 1. Unsaved data cannot be saved during sudden power outages, leading to the loss of work results; 2. Traditional UPS (Uninterruptible Power Supply) devices are bulky and require additional desktop space; 3. External UPS wiring is messy and affects the aesthetics of the desktop; 4. Some portable power solutions are not integrated with the host computer, making charging management inconvenient; 5. Existing monitor stands have limited functionality and have not explored the potential for integrated power supply. Utility Model Content

[0003] The purpose of this invention is to provide a desktop power supply device that integrates a backup battery into the monitor stand, thereby saving desktop space by installing the backup battery in the internal cavity of the monitor stand.

[0004] The technical solution adopted in this utility model is: A desktop computer power supply device integrating a backup battery in a monitor stand includes a monitor stand, a removable modular battery compartment disposed inside the monitor stand, and a power management chip integrated on the monitor motherboard. The modular battery compartment is electrically connected to the monitor's power management chip via a connecting cable between the monitor stand and the monitor. The modular battery compartment supplies power to the desktop computer by being connected in parallel with the host power supply via a backup cable passing through the monitor. When the host power supply is interrupted, the power management chip switches the modular battery compartment to supply power to the desktop computer.

[0005] Specifically, the monitor stand features a modular battery compartment inside the column, secured by a sliding slot or locking mechanism. The battery compartment contains internal metal heat sinks and insulating partitions to ensure safe battery operation. The entire interior of the battery compartment is encased in insulating silicone to prevent short circuits. The power interface features a reverse connection protection design, automatically disconnecting the circuit in case of incorrect insertion.

[0006] Furthermore, the monitor stand includes a base and a column fixed to the upper surface of the base; the monitor is mounted on the upper end of the column; a battery housing cavity is provided inside the column, and a modular battery compartment is detachably installed in the battery housing cavity.

[0007] Furthermore, the power management chip integrates a charging circuit; the power management chip charges the modular battery compartment when the display is powered by the host power supply.

[0008] Furthermore, the monitor stand has a reserved hidden DC power interface, which is electrically connected to the power management chip and is matched with and electrically connected to the host power adapter. Furthermore, the modular battery compartment is equipped with a power indicator light and an emergency charging port. The modular battery compartment supports bidirectional fast charging via a Type-C interface and is equipped with a power indicator light and an emergency charging port.

[0009] Specifically, the modular battery compartment uses the TP4056 charging chip, supports 5V / 2A input, and has overcharge, over-discharge, and short-circuit protection; the battery pack has a built-in PTC thermistor, which cuts off the charging circuit when the temperature exceeds 60℃.

[0010] Furthermore, the monitor stand secures the modular battery compartment via a sliding slot or locking mechanism, and the modular battery compartment has heat dissipation and insulation functions.

[0011] Furthermore, the monitor stand is made of aluminum alloy.

[0012] Specifically, the monitor stand is made of aluminum alloy profile, and the internal cavity diameter of the battery compartment is ≥50mm, which can accommodate an 18650 lithium battery pack (capacity ≥10000mAh); the battery compartment cover uses a magnetic or rotating lock, which supports quick removal in 3 seconds.

[0013] Furthermore, the power management chip integrates a voltage detection and switching circuit, which switches to modular battery power within 0.1 seconds when the host power supply voltage is lower than the threshold.

[0014] Specifically, it integrates an MCU control chip (such as STM32) to monitor the host power status and battery level in real time; it supports bidirectional fast charging via Type-C interface. The host power path and battery path are connected in parallel and automatically switched via an NMOS transistor, switching to battery power within 0.1 seconds when the host power is interrupted; the voltage detection circuit monitors the host power voltage in real time and triggers switching when it drops below 180V.

[0015] Furthermore, supporting power management software was developed to support battery status display, power-off protection policy settings, and automatic data saving. Additionally, a USB-HID interface driver was developed, allowing the host to identify the status of the modular battery compartment via USB; and it supports integration with Windows / macOS system power management APIs.

[0016] In addition, as a feasible implementation, the desktop application displays battery level, estimated battery life, and charge / discharge history; a save prompt window pops up when power is lost, and a shutdown script is automatically executed before the countdown ends. The host software displays battery status, charge / discharge records, and a power-off protection countdown; it supports customizable power-off protection strategies (such as a 10-minute delayed shutdown or manual saving). The modular battery compartment uses trickle charging to prevent overcharging and automatically pauses charging when the temperature is abnormal; it supports low-power standby of the battery when the host is in sleep mode, with power consumption ≤0.5W.

[0017] This invention adopts the above technical solution, using Type-C reverse power supply. Under normal circumstances, the battery is connected to the monitor for charging while the monitor is working. When an external power failure is detected, power switching is initiated, using the built-in battery to power the monitor, and then powering the PC through the monitor's reverse power supply. This invention integrates the backup power supply into the bracket, saving 30% of the desktop space occupied by traditional UPS systems; the power failure protection solves the pain point of desktop computers lacking built-in batteries, increasing data retention success rate to 99%; the removable battery design supports hot-swap, and a single battery can support continuous operation of the host for 30 minutes; the modular battery compartment is integrated with the bracket's appearance, keeping the desktop tidy.

[0018] This invention utilizes the internal cavity of the monitor bracket to install a backup battery, saving desktop space; the modular battery compartment automatically switches to battery power in the event of a sudden power outage, ensuring continuous operation of the host until data is saved; and the use of a detachable battery compartment module supports quick replacement of the modular battery compartment, meeting the needs of long-term use.
