[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This waterproof, compact, integrated charging and discharging power supply features a handle, input interface, cooling fan, output interface, discharge management module, temperature sensor, heat sink fins, and sealing potting compound. The handle on the right side of the rear casing enhances its outdoor portability. Waterproof connectors at the input and output interfaces prevent direct liquid contact. The sealing potting compound seals the connection between the front casing and the heat sink fins, while also conducting heat to the surface of the front casing, improving heat dissipation. The heat sink fins conduct heat generated by the electronic components on the circuit board to the top and bottom. The cooling fan draws in air from the vents, carrying away heat from the heat sink fins and expelling it, resulting in excellent heat dissipation. During charging, the lithium battery charge / discharge management chip in the discharge management module charges the battery pack. This module implements a standard constant current / constant voltage charging process based on the rated voltage of the lithium battery pack. During discharging, the inverter in the discharge management module converts the DC power from the battery pack into AC power output. Working in conjunction with the temperature sensor, it monitors the internal temperature in real time, managing battery charging and discharging to ensure safe operation.

[0013] 2. This waterproof, small-volume integrated charging and discharging power supply features a dustproof structure. When installing the dustproof net, align the net with the mounting groove and insert it inwards. As the dustproof net moves, the surface of the fixing plate contacts the inclined surface of the locking block, pushing the locking block into the sliding groove. This compresses the second spring. The surface of the dustproof net then contacts the push plate, squeezing the first spring. As the dustproof net and fixing plate move inwards into the mounting groove, the surface of the fixing plate no longer contacts the locking block. The second spring pushes the locking block downwards, causing its surface to engage with the fixing plate, thus fixing the fixing plate and dustproof net in the mounting groove, completing the dustproof net installation. To disassemble, pull the upper ring, which, through the limit block, moves the connecting rod upwards, causing the locking block to enter the sliding groove. The locking block no longer engages with the fixing plate. Under the action of the first spring, the push plate is dragged, pushing the fixing plate and dustproof net out of the mounting groove, allowing the dustproof net to be removed. The installation and disassembly of the dustproof net are convenient, requiring no tools and making it easy to use. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-6 One embodiment provided by this utility model:

[0023] A waterproof, compact, integrated charging and discharging power supply includes a front casing 1 and a rear casing 2, which are fixed together by bolts. A control panel 11 is fixedly connected to the surface of the front casing 1. Ventilation vents 12 are provided at the top and bottom of the front casing 1. A handle 21 is fixedly connected to the right side of the rear casing 2. An input interface 22 and a cooling fan 23 are fixedly connected to the right side of the rear casing 2. An output interface 24 is fixedly connected to the left side of the rear casing 2. A circuit board 25 is fixedly connected inside the rear casing 2. A discharge management module 26 and a temperature sensor 27 are fixedly connected to the surface of the circuit board 25. Heat sink fins 28 are fixedly connected to the surface of the circuit board 25. A sealing potting compound 29 is fixedly connected. A dustproof structure 3 is provided on the surface of the heat dissipation vent 12. The dustproof structure 3 includes a fixed frame 31 and a fixed block 37. The bottom of the fixed frame 31 has an installation groove 32. A spring 33 is fixedly connected to the inner wall of the installation groove 32. A push plate 34 is fixedly connected to the surface of the spring 33. A dustproof net 35 is slidably connected inside the installation groove 32. A fixed plate 36 is fixedly connected to one side of the dustproof net 35. A sliding groove 38 is provided at the bottom of the fixed block 37. A limit block 39 is slidably connected to the top of the fixed block 37. A pull ring 310 is rotatably connected to the top of the limit block 39. A connecting rod 311 is fixedly connected to the bottom of the limit block 39. A locking block 312 is fixedly connected to the bottom of the connecting rod 311. A spring is fixedly connected to the top of the locking block 312. The 2.313 module includes a handle 21, an input interface 22, a cooling fan 23, an output interface 24, a discharge management module 26, a temperature sensor 27, heat sink fins 28, and sealing potting compound 29. The handle 21 on the right side of the rear housing 2 increases the portability of the integrated power supply outdoors. Waterproof connectors at the input and output interfaces 22 and 24 prevent direct liquid contact. The sealing potting compound 29 seals the connection between the front housing 1 and the heat sink fins 28, while also transferring heat to the surface of the front housing 1, increasing heat dissipation. The heat sink fins 28 transfer heat generated by the electronic components on the circuit board 25 to the top and bottom. The cooling fan 23 draws air from the heat dissipation vent 12. The heat is drawn in, carrying away the heat from the surface of the heat sink fins 28 and expelling it through the cooling fan 23, resulting in good heat dissipation. During charging, the battery pack is charged via the lithium battery charge / discharge management chip in the discharge management module 26. This module implements a standard constant current and constant voltage charging process based on the rated voltage of the lithium battery pack. During discharging, the inverter in the discharge management module 26 converts the DC power of the battery pack into AC power output, which, in conjunction with the temperature sensor 27, monitors the internal temperature in real time and manages the battery charge / discharge to ensure safe operation. A dustproof structure 3 is provided. When installing the dustproof net 35, it is aligned with the mounting groove 32 and then inserted inward. When the dustproof net 35 moves, the surface of the fixing plate 36 contacts the inclined surface of the locking block 312, pushing the locking block 312 into the sliding groove 38.When spring 313 is compressed, the surface of the dustproof net 35 contacts the push plate 34 and presses against spring 33. As the dustproof net 35 and the fixing plate 36 move inward into the mounting groove 32, the surface of the fixing plate 36 no longer contacts the locking block 312. Spring 313 pushes the locking block 312 downward, causing its surface to engage with the fixing plate 36, thus fixing the fixing plate 36 and the dustproof net 35 in the mounting groove 32, completing the installation of the dustproof net 35. To disassemble, pull up the pull ring 310, which, through the limit block 39, moves the connecting rod 311 upward, causing the locking block 312 to enter the sliding groove 38. The locking block 312 no longer engages with the fixing plate 36, and under the action of spring 33, drags the push plate 34, thus pushing the fixing plate 36 and the dustproof net 35 out of the mounting groove 32, allowing the dustproof net 35 to be removed. The installation and disassembly of the dustproof net 35 is relatively convenient, requiring no tools and making it easy to use.

[0024] Furthermore, the cooling fan 23, the discharge management module 26, and the temperature sensor 27 are all electrically connected to the control panel 11. The discharge management module 26 includes a lithium battery charge / discharge management chip and an inverter. During charging, the battery pack is charged via the lithium battery charge / discharge management chip in the discharge management module 26. This module implements a standard constant current and constant voltage charging process based on the rated voltage of the lithium battery pack. During discharging, the inverter in the discharge management module 26 converts the DC power of the battery pack into AC power output. It works in conjunction with the temperature sensor 27 to monitor the internal temperature in real time. The cooling fan 23 can be directly controlled through the control panel 11. The lithium battery charge / discharge management chip is a common TIBQ series chip or other equivalent industrial standard chip, which is existing technology.

[0025] Furthermore, waterproof connectors are installed at the input interface 22 and the output interface 24 to prevent liquid from directly contacting the input interface 22 and the output interface 24.

[0026] Furthermore, the heat dissipation fins 28 are C-shaped. The front end of the heat dissipation fins 28 is bolted to the surface of the circuit board 25, and the rear end of the heat dissipation fins 28 is fixedly connected to the inner wall of the front housing 1 by sealing potting compound 29. The top and bottom of the heat dissipation fins 28 do not contact the top and bottom of the inner walls of the front housing 1 and the rear housing 2. The sealing potting compound 29 is a high thermal conductivity potting compound. The sealing potting compound 29 seals the connection between the front housing 1 and the heat dissipation fins 28 and conducts heat to the surface of the front housing 1, increasing the heat dissipation performance. The heat generated by the electronic components on the circuit board 25 is conducted to the top and bottom through the heat dissipation fins 28. The cooling fan 23 draws air in from the heat dissipation port 12, removes the heat from the surface of the heat dissipation fins 28, and exhausts it from the cooling fan 23.

[0027] Furthermore, the push plate 34 is slidably connected in the mounting groove 32, and the surface of the push plate 34 abuts against the dustproof net 35. When installing the dustproof net 35, the dustproof net 35 is aligned with the mounting groove 32 and then inserted inward. After the surface of the dustproof net 35 contacts the push plate 34, it compresses the spring 33.

[0028] Furthermore, the connecting rod 311 passes through the slide groove 38 and is fixedly connected to the limiting block 39. Both the connecting rod 311 and the locking block 312 are slidably connected within the limiting block 39. Pulling the pull ring 310 can move the connecting rod 311 through the limiting block 39, thereby adjusting the position of the locking block 312. At the same time, the limiting block 39 limits the position of the locking block 312 from the top of the fixing block 37.

[0029] Furthermore, the two ends of the second spring 313 are fixedly connected to the top of the locking block 312 and the top of the inner wall of the limiting block 39, respectively. The surface of the second spring 313 does not contact the surface of the connecting rod 311. The cross-section of the locking block 312 is triangular. When the dustproof net 35 moves, the surface of the fixing plate 36 contacts the inclined surface of the locking block 312, pushing the locking block 312 into the slide groove 38, so that the second spring 313 is compressed. As the dustproof net 35 and the fixing plate 36 move into the mounting groove 32, the surface of the fixing plate 36 no longer contacts the locking block 312. The second spring 313 pushes the locking block 312 down, so that the surface of the locking block 312 and the fixing plate 36 engage with each other, thereby fixing the fixing plate 36 and the dustproof net 35 in the mounting groove 32.

[0030] Working principle: When installing the dustproof net 35, align the dustproof net 35 with the mounting groove 32 and insert it inward. When the dustproof net 35 moves, the surface of the fixing plate 36 contacts the inclined surface of the locking block 312, pushing the locking block 312 into the sliding groove 38, compressing the second spring 313. After the surface of the dustproof net 35 contacts the push plate 34, it squeezes the first spring 33. As the dustproof net 35 and the fixing plate 36 move inward into the mounting groove 32, the surface of the fixing plate 36 no longer contacts the locking block 312, and the second spring 313 pushes the locking block 312 into the groove 38. When block 312 moves downward, its surface engages with the fixing plate 36, thus securing the fixing plate 36 and dustproof net 35 within the mounting groove 32. During disassembly, pulling the pull ring 310 causes the connecting rod 311 to move upward via the limit block 39, allowing block 312 to enter the sliding groove 38. Block 312 no longer engages with the fixing plate 36, and under the action of spring 33, it drags the push plate 34, pushing the fixing plate 36 and dustproof net 35 out of the mounting groove 32, allowing the dustproof net 35 to be removed. The heat generated by the electronic components on the circuit board 25 is conducted to the top and bottom through the heat sink fins 28. The cooling fan 23 draws air in from the heat dissipation port 12, removes the heat from the surface of the heat sink fins 28, and exhausts it from the cooling fan 23. The connection between the front shell 1 and the heat sink fins 28 is sealed by the sealing potting compound 29, which can also conduct heat to the surface of the front shell 1, increasing the heat dissipation performance. The handle 21 on the right side of the rear shell 2 increases the portability of the integrated power supply outdoors. Waterproof connectors are used at the input interface 22 and the output interface 24 to prevent liquid from directly contacting the input interface 22 and the output interface 24. During charging, the battery pack is charged by the lithium battery charge and discharge management chip of the discharge management module 26. This module implements a standard constant current and constant voltage charging process based on the rated voltage of the lithium battery pack. During discharging, the inverter of the discharge management module 26 converts the DC power of the battery pack into AC power output, and works with the temperature sensor 27 to monitor the internal temperature in real time.
