Technical Field
[0001] This utility model relates to the field of fast charging power supply technology, specifically a fast charging power supply with safety protection functions. Background Technology
[0002] With the popularization of new energy technologies and the increasing demand for outdoor living, outdoor power supplies (or portable energy storage power supplies) have become essential equipment for camping, road trips, fieldwork, and emergency preparedness. Their built-in large-capacity lithium-ion battery packs need to power various devices such as laptops, drones, rice cookers, and even power tools; therefore, their charging efficiency and convenience directly affect the user experience. With the rapid development of power electronics technology, fast charging technology is penetrating and expanding from traditional fixed charging stations into the field of portable outdoor power supplies.
[0003] High-power transmission (typically exceeding 100W) leads to significant heat accumulation, necessitating efficient heat dissipation solutions within limited spaces. High-voltage / high-current output increases the risk of contact resistance heating and electromagnetic radiation. In most cases, charging ports are plugged in without electrostatic protection. Furthermore, the energy storage batteries inside outdoor units are currently rigidly connected using mounting brackets, making it easy for vibrations to be transmitted to the batteries during collisions, causing damage.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4This utility model provides a technical solution: it includes a left shell 1 and a right shell 2. The bottom of the inner wall of the left shell 1 and the right shell 2 are both connected to a support base 3. The top of the support base 3 is connected to a power rack 4. The power rack 4 is internally connected to an energy storage power supply 5. Fan racks 6 are connected to both sides of the energy storage power supply 5. A cooling fan 7 is connected to one side of the fan rack 6. A user panel 9 is connected to one side of the left shell 1. A power interface and a power monitor 10 are connected to one side of the user panel 9. A delay switch 14 is provided on one side of the power interface. A side plate 15 is connected to one side of the inner wall of the left shell 1. A protective component is connected to one side of the side plate 15. A breathable mesh cover 24 is connected to both sides of the left shell 1 and the right shell 2. A main switch 25 is connected between the left shell 1 and the right shell 2. A base 26 is connected to the bottom of the left shell 1 and the right shell 2. Other electronic components that cooperate with the mobile power supply are provided in this application. Since they are common technologies, they are not described in detail in the specification. Reference Figure 3 As shown, the power supply frame 4 has a buffer concave end 41 on all four sides, and a vent hole is opened on one side of the buffer concave end 41. Limiting protrusions 8 are connected to both sides inside the power supply frame 4. A temperature sensor is connected to the inner side of one of the buffer concave ends 41. The bottom of the concave buffer end 41 is not connected to the bottom plate of the power supply frame 4, so it can be elastic by its own shape, which plays a buffering role and clamps the energy storage power supply 5. The limiting protrusions 8 located inside the buffer concave end 41 can limit the energy storage power supply 5.
[0017] Reference Figure 1 As shown, the power interface includes a slanted five-hole socket 11, a USB socket 12, and a round power socket 13. There are multiple delay switches 14, which are respectively set on one side of the slanted five-hole socket 11, USB socket 12, and round power socket 13, and are electrically connected to the slanted five-hole socket 11, USB socket 12, and round power socket 13. When using the slanted five-hole socket 11, USB socket 12, and round power socket 13, first insert the corresponding plug into the corresponding socket, and then press the delay switch 14. The power will be turned on after a delay of a few seconds. This avoids the danger of plugging in the plug, and if there is a leakage, it will not cause damage to personnel.
[0018] Reference Figure 4As shown, the protection components include an inverter 16 and a circuit board 17 mounted on one side of the side panel 15. A transformer 18, a controller 19, a surge protector 20, a current sensor 21, an ESD protection diode 22, and a TVS diode 23 are also connected to the side of the circuit board 17. The inverter 16 converts the power supply within panel 5 from DC to AC for outdoor use. The transformer 18 can boost the voltage according to the required power. During use, the surge protector 20 provides protection against electrical surges. The current sensor 21 monitors the current in each socket in real time. The ESD protection diode 22 provides electrostatic discharge protection for each socket. Combined with the TVS diode 23, it effectively resists instantaneous high-voltage surges caused by hot-plugging and electrostatic discharge, protecting the expensive protocol chips and power devices at the back end.
[0019] Surge protector 20, current sensor 21, ESD protection diode 22 and TVS diode 23, energy storage power supply 5, time delay switch 14 and power interface are electrically connected. The connection of time delay switch 14 forms a loop with each interface, which improves the safety of each interface.
[0020] A connecting bracket 27 and a docking bracket 28 are provided between the inner sides of the left housing 1 and the right housing 2. A corresponding mounting bracket is provided on one side of the left housing 1 corresponding to the power interface. The connecting bracket 27 between the left housing 1 and the right housing 2 is connected by connecting bolts. After installation, the docking bracket 28 between the left housing 1 and the right housing 2 is also plugged in to ensure connection stability. A handle is provided at the top of the left housing 1 and the right housing 2. The main switch 25 is located on one side of the left housing 1 and the right housing 2. The handles make it easy to pick up and put down, and convenient to carry.
[0021] The implementation principle of this application is as follows: When in use, the internal power supply frame 4, the buffer concave end 41, and the support base 3 located below the support base 3 provide protection for the energy storage power supply 5. The limiting protrusion 8 ensures the stability of the energy storage power supply 5 and guarantees its safe use. The delay switch 14 prevents immediate power supply when plugging into the socket, even if hands are wet, thus preventing immediate electric shock. Power is supplied to the corresponding socket only after the time set by the delay switch 14, providing a safety protection effect. At the same time, the internal current sensor 21 monitors the current of each socket in real time. In case of short circuit or leakage, the corresponding socket information is displayed through the power monitor 10 to remind the user. The protective components can monitor power consumption and protect the sockets, providing instantaneous overvoltage protection and electrostatic protection. The cooling fans 7 located on both sides of the power supply frame 4 provide cooling and heat dissipation, ensuring the heat dissipation of the internal energy storage power supply 5 and electronic components.
