Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically to a portable uninterruptible power supply box. Background Technology

[0002] A power supply box, also known as an external power supply, is a voltage conversion device for small portable electronic devices and appliances, commonly found in small electronic products such as laptops and computer mainframes. Its function is to convert AC mains power into a stable low voltage of approximately 5 to 20 volts, enabling these electronic products to operate normally. It typically consists of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board.

[0003] For large exhibition hosts and company work hosts, power supply boxes with built-in energy storage modules are generally used. Once the mains power is interrupted, the energy storage module can continue to supply power, preventing the host from shutting down directly. However, due to their size, portable power supply boxes cannot have built-in cooling fans or other heat dissipation methods. When the energy storage module supplies power, the temperature inside the power supply box will rise, which can easily cause the power supply box to stop working or even catch fire, posing a significant safety hazard. Therefore, there is an urgent need for a portable power supply box with high safety. Utility Model Content

[0004] This utility model provides a portable uninterruptible power supply box. The power supply box contains an energy storage module, and the outer shell of the power supply box is equipped with a heat-conducting plate that is in direct contact with the air. The energy storage module dissipates heat through contact with the heat-conducting plate via thermally conductive adhesive. This design can dissipate heat from the energy storage module and reduce the safety hazards of the power supply box.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A portable uninterruptible power supply (UPS) box is characterized by comprising a power box shell, a transformer module, an energy storage module, a circuit board, an input terminal, and an output terminal. The transformer module is mounted on the circuit board, and a heat-conducting sheet is provided on the power box shell. The energy storage module is in contact with the heat-conducting sheet through thermally conductive adhesive. When the input terminal is connected to external AC power, the transformer module transforms the external power into DC power to charge the energy storage module and output it through the output terminal. When the AC power is disconnected, the energy storage module outputs the transformed power through the output terminal.

[0007] Preferably, a heat-conducting frame is provided on the circuit board. The heat-conducting frame absorbs the heat emitted by the circuit board and the transformer module, which can effectively reduce the temperature of the circuit board and the transformer module and prevent them from stopping work or even being damaged due to high temperature protection.

[0008] Preferably, the heat-conducting frame contacts the heat-conducting sheet through thermally conductive adhesive. The thermally conductive adhesive can transfer the heat of the heat-conducting frame to the heat-conducting sheet for heat dissipation. The thermal conductivity of the thermally conductive adhesive is greater than that of air, which can dissipate heat more effectively.

[0009] Preferably, a support block is provided at the bottom of the energy storage module, and the energy storage module is fixed together with the support block inside the power box shell with insulating glue, which can avoid the impact of vibration on the energy storage module during carrying.

[0010] Preferably, the lower part of the energy storage module contacts the circuit board through thermally conductive adhesive. The thermally conductive adhesive can transfer the heat emitted by the energy storage module to the circuit board, and then dissipate heat through the thermally conductive frame, which can assist in the heat dissipation of the energy storage module.

[0011] Preferably, the heat-conducting sheet and the power box shell are integrally molded using injection molding, which can improve the airtightness of the heat-conducting sheet and the power box shell, and has a certain waterproof effect, which can meet most daily waterproof needs.

[0012] Preferably, the heat-conducting plate is a metal heat sink or an alloy heat sink. Metal or alloy has good thermal conductivity, which can enhance the heat dissipation of the power supply box.

[0013] Preferably, a display screen is provided on the outer shell of the power supply box. The display screen can show the remaining power of the energy storage module, making it convenient for users to plan their power consumption.

[0014] The beneficial effects of this disclosure are as follows:

[0015] This utility model has an additional energy storage module inside the power supply box. When the mains power is connected to the input terminal, the circuit board not only controls the transformer module to transform the external power into DC power for output from the output terminal, but also charges the energy storage module. After the energy storage module is fully charged, if the mains power is suddenly disconnected, but the exhibition host or company host is still working, the circuit board detects that the output terminal still needs to output, and controls the energy storage module to transform the voltage through the transformer module to a voltage suitable for the exhibition host or company host, so as to avoid losses caused by host shutdown.

[0016] Portable power supply boxes, due to their size limitations, cannot have built-in cooling fans for heat dissipation like computer power supplies. Therefore, this invention incorporates heat-conducting pads on the outer shell of the power supply box. These pads help dissipate heat from inside the power supply box into the air, preventing heat buildup. Furthermore, to improve heat dissipation efficiency, thermally conductive adhesive is used to directly contact the heat-conducting pads and the power module. The thermal conductivity of this adhesive is higher than that of air, effectively improving heat dissipation efficiency and enhancing the applicability and safety of the portable power supply box.

[0027] A portable uninterruptible power supply box is characterized by comprising a power box shell 1, a transformer module 2, an energy storage module 3, a circuit board 4, an input terminal 5, and an output terminal. The transformer module 2 is mounted on the circuit board 4. A heat-conducting sheet 6 is provided on the power box shell 1. The energy storage module 3 is in contact with the heat-conducting sheet 6 through thermally conductive adhesive 7. When the input terminal 5 is connected to external AC power, the transformer module 2 transforms the external power into DC power to charge the energy storage module 3 and outputs it through the output terminal. When the AC power is disconnected, the energy storage module 3 is transformed by the transformer module 2 and output through the output terminal.

[0028] Preferably, a heat-conducting frame 8 is provided on the circuit board 4. The heat-conducting frame 8 absorbs the heat emitted by the circuit board 4 and the transformer module 2, which can effectively reduce the temperature of the circuit board 4 and the transformer module 2, and prevent the high-temperature protection from stopping work or even being damaged.

[0029] Preferably, the heat-conducting frame 8 is in contact with the heat-conducting sheet 6 through the heat-conducting adhesive 7. The heat-conducting adhesive 7 can transfer the heat of the heat-conducting frame 8 to the heat-conducting sheet 6 for heat dissipation. The thermal conductivity of the heat-conducting adhesive 7 is greater than that of air, so it can dissipate heat more effectively.

[0030] Preferably, a support block 9 is provided at the bottom of the energy storage module 3. The energy storage module 3 is fixed inside the power box shell 1 together with the support block 9 by insulating glue, which can avoid the impact of vibration on the energy storage module 3 during carrying.

[0031] Preferably, the lower part of the energy storage module 3 is in contact with the circuit board 4 through the thermally conductive adhesive 7. The thermally conductive adhesive 7 can transfer the heat emitted by the energy storage module 3 to the circuit board 4, and then dissipate heat through the thermally conductive frame 8, which can assist the energy storage module 3 in dissipating heat.

[0032] Preferably, the heat-conducting sheet 6 and the power box shell 1 are integrally molded using injection molding, which can improve the airtightness of the heat-conducting sheet and the power box shell 1, and has a certain waterproof effect, which can meet most daily waterproof needs.

[0033] Preferably, the heat-conducting plate 6 is a metal heat sink or an alloy heat sink. Metal or alloy has good thermal conductivity, which can enhance the heat dissipation of the power supply box.

[0034] Preferably, a display screen 10 is provided on the outer shell 1 of the power supply box. The display screen 10 can display the remaining power of the energy storage module 3, so as to facilitate the user to plan the use of electricity.

[0035] The usage and working methods of this disclosure are as follows:

[0036] Connect the input terminal 5 of the power supply box to the mains power and the output terminal of the power supply box to the exhibition host. At this time, the energy storage module 3 is in charging mode and is powered by the mains power from the output terminal. When the mains power suddenly disconnects and the exhibition host is still working, the circuit board 4 will control the energy storage module 3 to supply power to the output terminal to ensure that the exhibition host will not stop directly. When the energy storage module 3 is powered, the heat emitted by the energy storage module 3 is transferred to the heat conduction sheet 6 through the thermal conductive adhesive 7 and then dissipated into the air by the heat conduction sheet 6.

[0037] The beneficial effects of this disclosure are as follows:

[0038] This utility model has an additional energy storage module 3 inside the power supply box. When the input terminal 5 is connected to the mains power, the circuit board 4 not only controls the transformer module 2 to transform the external power into DC power and output it from the output terminal, but also charges the energy storage module 3. After the energy storage module 3 is fully charged, if the mains power is suddenly disconnected, but the exhibition host or company host is still working, the circuit board 4 detects that the output terminal still needs to output, and controls the energy storage module 3 to transform the voltage through the transformer module 2 to a voltage suitable for the exhibition host or company host, so as to avoid losses caused by the host shutdown.

[0039] Portable power supply boxes, due to their size limitations, cannot have built-in cooling fans for heat dissipation like computer power supplies. Therefore, this invention provides a heat-conducting plate 6 on the outer shell 1 of the power supply box. The heat-conducting plate 6 helps dissipate the heat inside the power supply box into the air, preventing heat accumulation inside the power supply box. At the same time, to improve heat dissipation efficiency, thermally conductive adhesive 7 directly contacts the heat-conducting plate 6 and the power module. The thermal conductivity of the thermally conductive adhesive 7 is higher than that of air, which can effectively improve heat dissipation efficiency and enhance the applicability and safety of the portable power supply box.

[0040] Therefore, this utility model provides a portable uninterruptible power supply box, in which an energy storage module is installed inside the power supply box, and a heat-conducting plate is installed on the outer shell of the power supply box. The heat-conducting plate is in direct contact with the air, and the energy storage module dissipates heat through contact with the heat-conducting plate via thermally conductive adhesive. This can dissipate heat from the energy storage module and reduce the safety hazards of the power supply box.
