Description

Technical Field

[0001] This utility model relates to the field of power bank technology, specifically a power bank with PD high-power discharge. Background Technology

[0002] A power bank, also known as a portable charger or travel charger, is a portable charger that integrates power supply and charging functions. It allows you to charge mobile phones, tablets, and other digital devices anytime, anywhere. It typically uses lithium-ion batteries (or less commonly, dry-cell batteries) as its energy storage unit, offering convenience and speed. PD fast charging refers to a fast charging technology, a standard for charging mobile devices. PD fast charging technology achieves faster charging speeds by increasing voltage and power output. Compared to traditional USB charging, PD fast charging can provide higher power output, enabling devices to charge faster.

[0003] Two-way PD fast charging power banks are a type of power bank. Fast charging power banks generate a lot of heat when working, and they only dissipate heat through openings, which has poor heat dissipation performance and cannot effectively dissipate heat in time, thus reducing the lifespan of the fast charging power bank.

[0004] Chinese patent CN 222464176 U discloses a portable bidirectional PD fast charging power bank. Although it can effectively dissipate heat from the power bank, the heat dissipation structure of this patent is complex, has high process requirements, increases production costs, and makes it inconvenient to quickly assemble the power bank.

The upper and lower ends of the fixing board are connected to the fixing block by screws, and the anti-slip pad is in contact with the outer end of the lithium battery.

[0010] Furthermore, each heat sink is provided with pressure plates on both the left and right sides of one end. The pressure plates are Z-shaped, with one end of the pressure plate connected to the heat sink by screws and the other end connected to the connector plate by screws.

[0011] Furthermore, the width of the heat dissipation fin gradually narrows at the end furthest from the heat dissipation plate.

[0012] Furthermore, several heat dissipation fins are arranged in parallel, and the thickness and width of the heat dissipation fins gradually decrease from the inside to the outside.

[0023] 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, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a PD high-power discharge power bank, including: a shell 1 and a lithium battery 9. One end of the shell 1 is provided with several heat dissipation holes 5, and the other end of the shell 1 is open. Plug-in plates 7 are fixedly installed on the inner walls of the upper and lower sides of the left and right ends of the shell 1. One end of the lithium battery 9 is inserted into the inner side of the four plug-in plates 7, and the lithium battery 9 is located between the four plug-in plates 7. Fixing plates 12 are provided on the left and right sides of one end of the lithium battery 9. The upper and lower ends of the fixing plates 12 are fixed to the outer walls of the plug-in plates 7 by screws. A fixing block 10 is fixedly installed on the outer end of each plug-in plate 7. An anti-slip pad 13 is fixedly installed on the inner end of each fixing plate 12. The upper and lower ends of the fixing plates 12 are connected to the fixing blocks 10 by screws. At the same time, the anti-slip pad 13 contacts the outer end of the lithium battery 9, fixing the lithium battery 9 inside the shell 1, which facilitates the installation and removal of the lithium battery 9.

[0025] Heat sinks 14 are fixedly installed on the outer walls of the upper and lower ends of the lithium battery 9. Several vertical heat sink fins 16 are fixedly installed on the outer end of each heat sink 14. Several horizontal heat sink fins 17 are fixedly installed on the outer wall of each heat sink fin 16. Pressure plates 15 are provided on the left and right sides of one end of each heat sink 14. The pressure plates 15 are Z-shaped. One end of the pressure plate 15 is connected to the heat sink 14 by screws, and the other end is connected to the plug plate 7 by screws, which fixes the heat sink 14, heat sink fins 16 and heat sink fins 17, and facilitates the disassembly and assembly of the heat sink 14, heat sink fins 16 and heat sink fins 17.

[0026] The width of the end of the heat dissipation fin 16 away from the heat dissipation plate 14 gradually narrows. Several heat dissipation fins 17 are arranged in parallel, and the thickness and width of the heat dissipation fins 17 gradually decrease from the inside to the outside. During the charging and discharging process, the lithium battery 9 generates heat and transfers the heat to the heat dissipation plate 14. The heat dissipation plate 14 transfers the heat to the heat dissipation fins 16 and 17, increasing the contact area with the air and improving the efficiency of heat exchange, thereby cooling the lithium battery 9. According to the principle of heat transfer, the closer to the heat dissipation plate 14, the higher the efficiency of heat transfer. The volume of the heat dissipation fins 16 and 17 away from the heat dissipation plate 14 becomes smaller and smaller, saving materials without affecting the heat dissipation of the lithium battery 9.

[0027] The other end of the outer casing 1 is fixedly mounted with a base plate 2 by screws. Several heat dissipation holes 3 are evenly distributed on the side wall of the base plate 2. A cooling fan 18 is fixedly mounted on the inner end of the base plate 2. The cooling fan 18 is electrically connected to the controller 6. The cooling fan 18 can be started by the controller 6. When the cooling fan 18 rotates, it blows air onto the heat sink 14, the first heat sink 16 and the second heat sink 17. The air carries away the heat from the heat sink 14, the first heat sink 16 and the lithium battery 9, achieving the effect of quickly dissipating heat from the lithium battery 9.

[0028] like Figure 3 and Figure 4 As shown, in some embodiments, a rubber pad 8 is fixedly installed on the inner end of each plug-in board 7, and the outer end of the lithium battery 9 contacts the inner side of the rubber pad 8. More specifically, the rubber pad 8 serves to protect the lithium battery 9 and prevent the lithium battery 9 from shaking within the four plug-in boards 7.

[0029] like Figure 4 and Figure 5 As shown, in some embodiments, limit sleeves 11 are fixedly installed on all four sides of the inner end of the outer shell 1 near the bottom plate 2, and limit posts 19 are fixedly installed on all four sides of one end of the bottom plate 2. More specifically, when the bottom plate 2 is fixed on the outer shell 1, the limit posts 19 are inserted into the limit sleeves 11, which further strengthens the firmness of the installation of the bottom plate 2.

[0030] like Figure 1 As shown, in some embodiments, a temperature sensor 4 is fixedly installed on the inner wall of the middle part of one side of the outer casing 1, and a controller 6 is fixedly installed at one end of the outer casing 1. The controller 6 and the temperature sensor 4 are electrically connected. More specifically, a temperature value range is input in advance into the controller 6. The temperature sensor 4 can detect the temperature inside the power bank and transmit it to the controller 6. When the temperature sensor 4 detects that the temperature inside the power bank exceeds the pre-set temperature value, the controller 6 starts the cooling fan 18 to cool down the lithium battery 9.

[0031] Working principle: When the lithium battery 9 is working, it generates heat and transfers the heat to the heat sink 14, heat sink fin 16 and heat sink fin 17 for heat dissipation. The temperature sensor 4 detects the temperature inside the power bank in real time and transmits it to the controller 6. When the temperature sensor 4 detects that the temperature inside the power bank exceeds the preset temperature value, the controller 6 starts the cooling fan 18 to cool the lithium battery 9. When the temperature detected by the temperature sensor 4 is lower than the preset temperature value, the controller 6 turns off the cooling fan 18.

[0032] 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.
