The surface of the compartment 101 features a sliding plate 107 structure, combining protection and storage functions. The capacitor body 2 is connected to the internal circuitry of the capacitor compartment 1, enabling rapid power replacement. When the power is depleted, a new power supply can be directly replaced without interrupting device operation. This is existing technology and will not be elaborated further. The heat dissipation vent 3 employs a dual-fan collaborative working mode, utilizing directional airflow and convection circulation design for enhanced heat dissipation.

[0027] refer to Figure 1-5 The capacitor compartment 1 includes a compartment body 101. A handle 102 is fixedly connected to the upper surface of the compartment body 101.

The display 105 integrates a digital display of power and a charging status indicator. It can work normally in an ambient temperature range of -20℃ to 60℃. This is existing technology and will not be described in detail. Rubber anti-slip pads are set at the four corners of the bottom of the housing 101 to effectively reduce vibration and noise generated during placement.

[0029] refer to Figure 1-5 A sliding groove 106 is fixedly connected to the surface of the silo body 101, and a sliding plate 107 is slidably connected inside the sliding groove 106. A door frame 108 is fixedly connected to the surface of the silo body 101, and a limit plate 109 is fixedly connected to one side of the sliding plate 107.

[0030] Specifically, the slide 106 is made of high-precision stainless steel with a polished surface to reduce friction when the sliding plate 107 slides, ensuring smooth sliding. The sliding plate 107 is made of lightweight aluminum alloy, which reduces the overall weight while ensuring strength. The door frame 108 and the compartment 101 are firmly connected by welding. The limit plate 109 is made of rubber and has a certain degree of elasticity. When the sliding plate 107 slides to the designated position, the limit plate 109 can effectively prevent the sliding plate 107 from continuing to slide, playing a role in positioning and buffering.

[0031] refer to Figure 1-5The capacitor body 2 includes a quick-release power supply 201, and a USB interface 202 is fixedly disposed on the surface of the quick-release power supply 201.

[0032] Specifically, the quick-release power supply 201 adopts a modular design with a flame-retardant ABS shell. It integrates a lithium-ion battery pack and intelligent protection circuit. The USB interface 202 supports the 5V / 2.4A fast charging protocol, which is existing technology and will not be elaborated further. The interface surface is gold-plated to improve conductivity and corrosion resistance. The quick-release power supply 201 and capacitor compartment 1 are connected by a slot structure to achieve tool-free quick assembly and disassembly, ensuring correct installation direction. At the same time, the interface area adopts a silicone sealing ring waterproof design, achieving an IPX5 protection level.

[0033] refer to Figure 1-5 A support base 203 is fixedly connected to one side of the interior surface of the hopper 101, a power cord 204 is fixedly connected to the other side of the interior surface of the hopper 101, a fixing plate 205 is fixedly connected to the interior surface of the hopper 101, a displacement plate 206 is connected inside the fixing plate 205, and a rivet 207 is fixedly connected to the upper surface of the fixing plate 205.

[0034] Specifically, the support base 203 is made of engineering plastic injection molding and has an internal elastic buckle structure to ensure that the quick-release power supply 201 is installed firmly and is easy to disassemble. The power cord 204 is made of flexible TPE material and is wrapped with a braided mesh tube to enhance its tensile strength. The fixing plate 205 is fastened to the compartment 101 by rivets 207. The displacement plate 206 can slide inside the fixing plate 205 to adjust the internal space layout and fix quick-release power supplies 201 of different sizes.

[0035] refer to Figure 1-5 The heat dissipation vent 3 includes a fan box 301, a fan 302 is fixedly mounted on the surface of the fan box 301, and a heat exhaust pipe 303 is fixedly mounted on the surface of the fan box 301.

[0036] Specifically, the air box 301 is made of aluminum alloy with good thermal conductivity and the surface is anodized to improve corrosion resistance. The fan 302 is a low-noise, high-airflow DC fan. The heat dissipation pipe 303 adopts a corrugated pipe design, which can effectively increase the heat dissipation area and reduce the phenomenon of hot air backflow, thus affecting the normal operation of the equipment.

[0037] refer to Figure 1-5 A mounting base 304 is fixedly installed on the back of the compartment 101. A fan 305 is fixedly connected to the upper surface of the mounting base 304. Heat dissipation holes 306 are fixedly installed on the back surface of the compartment 101.

[0038] Specifically, the mounting base 304 is made of metal and is tightly connected to the chamber 101 with bolts to ensure that the second fan 305 is installed firmly and will not loosen or make abnormal noise during equipment operation. The second fan 305 also uses a low-noise, high-airflow DC fan, which works in conjunction with the first fan 302 to form an efficient convection circulation cooling system. The heat dissipation holes 306 are arranged in a regular pattern, and the hole size is designed and has a filter screen inside. This ensures sufficient airflow and effectively prevents dust and other foreign objects from entering the chamber 101 and affecting the performance and service life of the equipment.

[0039] Working Principle: When the composite power bank is working, the quick-release power supply 201 in the capacitor body 2 begins to discharge, providing power support for various connected terminal devices. As the device continues to operate, the battery pack inside the quick-release power supply 201 generates heat. At this time, the heat dissipation mechanism starts working, and fan 1 302 starts, blowing air out of the air box 301. Through the heat dissipation pipe 303, a directional airflow is formed, carrying away the heat generated inside the capacitor compartment 1. At the same time, fan 2 305 on the back of the compartment 101 also starts to operate, forming a convection circulation with the heat dissipation hole 306. Outside cold air enters the compartment 101 through the heat dissipation hole 306, exchanges with the hot air, and is then drawn out by fan 2 305, forming a continuous airflow. In terms of operation, the user can control the power supply by pressing the switch 104. The internal fan 1 302 and the rear fan 2 305... The power supply for the 05 is connected to its internal power source via a circuit. When it is necessary to check the remaining power, simply press the switch 104 once, and the high-brightness LED screen display 105 will clearly show the remaining power percentage. When the power supply 201 is depleted, the user does not need to interrupt the use of the device. Simply remove the power supply 201 from the support base 203 and replace it with a new power supply 201 to continue powering the terminal device. This is existing technology and will not be described in detail. In addition, the sliding plate 107 can slide within the slide groove 106. When the USB interface 202 is not in use, the sliding plate 107 can be moved along the slide groove 106 to completely cover the area of ​​the USB interface 202 to prevent dust from entering.
