Description

Technical Field

[0001] This utility model belongs to the field of power supply technology, and in particular relates to an integrated power supply for photovoltaic energy storage and charging. Background Technology

[0002] With the increasing prevalence of electric low-speed vehicles, home appliances, and mobile devices, a single discharge interface cannot meet diverse needs. Integrating functions such as 220V household power, USB charging, and 24VDC output is becoming the trend. The coulomb counter display can show the remaining power, charging / discharging status, and energy consumption data in real time, improving user experience and optimizing energy management. Through communication interfaces such as RS-232 and CAN, the device can connect to vehicle networking systems and energy management platforms to achieve remote monitoring, fault diagnosis, and scheduling optimization.

[0003] Existing integrated photovoltaic-storage-charging power supplies generally include a unidirectional inverter. In photovoltaic power generation systems, the unidirectional inverter is typically used to convert the direct current generated by the solar panels into alternating current that can be fed into the grid. When installing the unidirectional inverter inside the integrated photovoltaic-storage-charging power supply, it is usually necessary to use bolts for fixing. However, the mounting hole positions of a typical unidirectional inverter are fixed and cannot be changed. If the mounting hole positions inside the integrated photovoltaic-storage-charging power supply do not correspond to the mounting hole positions of the unidirectional inverter, installation is not possible, reducing the applicability of the device. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated photovoltaic, energy storage, and charging power supply to solve the problems mentioned in the background art, including:

[0005] The power supply unit, which is used to complete charging and discharging;

[0006] A unidirectional inverter, which is installed inside the power supply unit;

[0007] The mounting assembly is used to mount a unidirectional inverter into the power supply body. The mounting assembly includes two first plates that can be moved away from or close to each other. The edges of the first plates are provided with a plurality of second slots for mounting bolts.

[0008] Preferably, the mounting components further include:

[0009] The pole is fixedly installed on the unidirectional inverter;

[0010] A bidirectional lead screw that passes through a rod body and is rotatably connected to the rod body. The bidirectional lead screw passes through two first plates and is threadedly connected to the two first plates.

[0011] Preferably, a first groove is formed in the rod body, and a driving component is provided in the first groove, which can drive the bidirectional lead screw to rotate.

[0012] Preferably, the driving component is a knob, which is disposed in the first groove and is fixed to the bidirectional lead screw.

[0013] Preferably, the driving component is a dual-output shaft motor, which is fixedly installed in the first slot. The output end of the dual-output shaft motor is fixed to the bidirectional lead screw, and the dual-output shaft motor is capable of self-locking and reversing.

[0014] Preferably, a third groove is formed in the first plate, and a second plate is fixedly connected to both ends of the bidirectional lead screw. The second plate is larger than the diameter of the bidirectional lead screw and is disposed in the third groove.

[0015] Preferably, the second plate and the third slot are adapted to each other and can slide along the third slot, and the two first plates can slide along the surface of the unidirectional inverter.

[0016] This application uses a drive component to rotate a bidirectional lead screw, which in turn causes two first plates to slide closer to or further away from the unidirectional inverter. The positions of the second slots on the two first plates also change, thus adapting to the mounting holes at different positions inside the power supply body. This allows the unidirectional inverter to be installed inside power supply bodies of different sizes, improving the applicability of the device. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0025] To enable the unidirectional inverter 200 to be installed inside power supply units 100 of different sizes, this embodiment provides an integrated photovoltaic-storage-charging power supply, such as... Figure 1 and Figure 2 As shown, it includes: a power supply body 100 for charging and discharging, a unidirectional inverter 200 for converting current, and a mounting assembly 300 for connecting the power supply body 100 and the unidirectional inverter 200.

[0026] like Figure 1 As shown, the power supply unit 100 is existing technology, used to complete charging and discharging. Specifically, the 48V 105Ah battery can be directly connected to the corresponding low-speed vehicle controller to power the vehicle; the 220V household power output and USB output are output from the 48V 105Ah battery with an internal unidirectional inverter, converting DC 48V to AC 220V and DC 5V output; the 24VDC power output is converted from the 48V to 24VDC power supply inside the 48V 105Ah battery; the coulomb meter display uses a coulomb meter sampler to accurately measure the power, thereby outputting the corresponding SOC, voltage, current, etc. to the display screen; the built-in MPPT can perform photovoltaic charging, converting light energy into DC power to charge the battery.

[0027] like Figure 2 As shown, the unidirectional inverter 200 is a prior art technology. It is installed inside the power supply unit 100 and electrically connected to the power supply unit 100, and is used to convert the direct current generated by the solar panel into alternating current that can be fed into the power grid.

[0028] like Figure 4 As shown, the mounting assembly 300 is used to install the unidirectional inverter 200 inside the power supply body 100. The mounting assembly 300 includes two first plates 330, which are slidable along the surface of the unidirectional inverter 200. The two first plates 330 can move away from or closer to each other (the implementation is detailed below). Two second grooves 331 are formed on the edges of the first plates 330. The second grooves 331 are used to install bolts. When the two first plates 330 move away from or closer to each other, the position of the second grooves 331 also changes, thereby adapting to the mounting holes at different positions inside the power supply body 100. This allows the unidirectional inverter 200 to be installed inside power supply bodies 100 of different sizes, improving the applicability of the device. Specifically, as shown... Figure 4As shown, the mounting assembly 300 also includes: a rod body 310, a bidirectional lead screw 320, and a drive component 340.

[0029] The rod body 310 is a rectangular long rod, fixedly installed at the bottom of the unidirectional inverter 200. A first slot 311 is formed within the rod body 310. A driving component 340 is installed within the first slot 311, capable of driving a bidirectional lead screw 320 to rotate. In one embodiment, the driving component 340 is a knob, located within the first slot 311 and fixed to the bidirectional lead screw 320. Manually rotating the knob drives the bidirectional lead screw 320, making the device more energy-efficient. In another embodiment, the driving component 340 is a dual-output shaft motor, fixedly installed within the first slot 311. The output end of the dual-output shaft motor is fixed to the bidirectional lead screw 320. The dual-output shaft motor can... Self-locking and reversible, the device is more automated by starting the dual-output shaft motor to drive the bidirectional lead screw 320 to rotate. The bidirectional lead screw 320 is a long, round rod with two threads in opposite directions on its outer wall. The two threads are respectively located on two opposite faces of the rod body 310 and pass through the rod body 310. The bidirectional lead screw 320 and the rod body 310 are rotatably connected by bearings, allowing the bidirectional lead screw 320 to rotate itself with the help of the rod body 310. The two threads of the bidirectional lead screw 320 pass through and are threadedly connected to the two first plates 330. When the drive unit 340 drives the bidirectional lead screw 320 to rotate, the bidirectional lead screw 320 drives the two first plates 330 to slide closer to or further away from the unidirectional inverter 200, thereby adjusting the position of the second slot 331.

[0030] To prevent the two first plates 330 from detaching from the bidirectional lead screw 320, a further solution is as follows: Figure 4 As shown, a third groove 332 is formed in the first plate 330. The third groove 332 is rectangular. A second plate 350 is fixedly connected to both ends of the bidirectional lead screw 320. The second plate 350 is square and larger than the diameter of the bidirectional lead screw 320. The second plate 350 is disposed in the third groove 332. The second plate 350 and the third groove 332 are compatible and can slide along the third groove 332. When the two first plates 330 are driven by the bidirectional lead screw 320 and slide closer or further away from the unidirectional inverter 200, the position of the second plate 350 inside the third groove 332 will also change. When the second plate 350 moves to the edge of the third groove 332, the first plate 330 can no longer be moved, so that the first plate 330 will not detach from the bidirectional lead screw 320, thus improving the stability of the device.
