[0031] [Hardware Structure of Inverter Energy Storage Device]

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 This is a schematic diagram of an inverter energy storage device according to an embodiment of the present invention. Figure 2 This is an exploded view of an inverter energy storage device according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the cover opening of the inverter energy storage device according to an embodiment of the present utility model. Figure 4 for Figure 3 A magnified view of section IV in the image.

[0033] The inverter energy storage device 1 provided in this embodiment is illustrated by the structure of the power control box 2. The inverter energy storage device 1 described herein is used as a power supply device. For example, this power supply device can provide various power conversion processes, allowing various power sources (such as AC or DC power) to be input or output to meet various user power needs. The inverter energy storage device 1 of this invention can accommodate and use the relevant transmission lines (such as power lines or network cables) used by this power supply device.

[0034] For example, such as Figure 1 The power control box 2 used in the inverter energy storage device 1 shown includes a housing 20 and a cover 22. The cover 22 can be opened or closed relative to the housing 20. Figure 1 The cover 22 shown moves inside the housing 20 to a closed state, and Figure 3 The cover 22 shown is moved outside the housing 20 to be in an open state. The open state here means that personnel can perform wiring work on the various transmission lines inside the inverter energy storage device 1, and the closed state here means that personnel can no longer perform wiring work on the various transmission lines inside the inverter energy storage device 1.

[0035] In addition to the power control box 2, the inverter energy storage device 1 also includes a power supply circuit 10 installed inside the power control box 2. This power supply circuit 10 has different designs depending on the power requirements, and may include different combinations of AC / DC conversion circuits, DC / DC conversion circuits, protection circuits, switching circuits, detection circuits, inverter circuits, maximum power point tracking circuits, charging circuits, energy storage circuits (such as battery packs), communication circuits, or related control circuits. Furthermore, when the inverter energy storage device 1... Figure 3 When in the ON state, the wiring area of ​​the power circuit 10 can be exposed outside the housing 20 to facilitate personnel construction operations.

[0036] In one embodiment, the housing 20 has an opening 201, a receiving portion 203, a guide portion 205, and a support portion 207, wherein the receiving portion 203 is disposed inside the housing 20, such as Figure 2 The power circuit 10 shown is disposed in this receiving portion 203. An opening 201 is formed on one side of the housing 20 and is adjacent to the receiving portion 203, meaning the opening 201 communicates with the receiving portion 203, allowing personnel to perform various construction operations on the components inside the housing 20 through the opening 201. A guide portion 205 is disposed inside the housing 20 and adjacent to the opening 201 and the receiving portion 203, allowing the cover plate 22 to move on the guide portion 205. The cover plate 22 can move to different positions on the guide portion 205 via different guiding directions. For example, the range of movement of the cover plate 22 on the guide portion 205 can pass through the opening 201 and the support portion 207, thereby controlling whether the opening 201 is in the correct position. Figure 1 Covered by cover plate 22 or as Figure 3 It is exposed. The support part 207 is located inside the housing 20 and is used to support the open cover 22 for use. The support part 207 can be flipped to control whether to provide support to the cover 22.

[0037] To further illustrate how the cover 22 moves on the guide portion 205, the guide portion 205 can provide different guiding directions. For example, the cover 22 can move into the housing 20 in the first guiding direction. When the cover 22 moves to the open position on the guide portion 205, the receiving portion 203 is exposed through the opening 201. Figure 3 As shown. On the other hand, when the cover 22 moves outward from the housing 20 along the second direction of the guide direction, where the second direction is opposite to the first direction, and when the cover 22 moves to the closed position on the guide portion 205, the cover 22 can then... Figure 1 The shown shielding opening 201.

[0038] It is worth noting that the guide portion 205 includes a first guide groove 2051 and a second guide groove 2052. The first guide groove 2051 is disposed on the first side of the housing 20, and the second guide groove 2052 is disposed on the second side of the housing 20. The first and second sides of the housing 20 are opposite sides, and the first side of the housing 20 is parallel to the second side of the housing 20. The support portion 207 is disposed between the first guide groove 2051 and the second guide groove 2052. The first guide groove 2051 and the second guide groove 2052 have the same length and are respectively greater than the length of the cover plate 22 in the extending direction of the guide portion 205. This ensures that the movement range of the cover plate 22 can effectively cover the positions of the opening 201 and the support portion 207.

[0039] It should be noted that when the cover 22 is moved to the open position, most of the area of ​​the cover 22 is below the panel 200 of the housing 20, meaning that the opening 201 and the support 207 are exposed, allowing personnel to... Figure 3 The image shows the accommodating portion 203 inside the housing 20 as seen from the outside of the housing 20. The location of the wiring area of ​​the power circuit 10 corresponds to the opening 201, so that when the cover 22 is moved to the open position, the wiring area of ​​the power circuit 10 is exposed outwards through the opening 201. Furthermore, when the cover 22 is moved to the closed position, it is exposed outside the housing 20, meaning the opening 201 is completely covered by the cover 22, allowing personnel to... Figure 1 As shown, only the cover plate 22 is visible from the outside of the housing 20, but the internal accommodating part 203 of the housing 20 is no longer visible.

[0040] In one embodiment, the length between the open and closed positions is greater than the length of the cover plate 22 in the extending direction of the guide portion 205 and less than the length of the guide portion 205. The length of the opening 201 in the extending direction of the guide portion 205 is less than the length of the guide portion 205. The open position is when the cover plate 22 can be moved to the topmost position inside the housing 20 when it is open, and the closed position is when the cover plate 22 can be moved to the bottommost position of the housing 20 when it is closed. The area of ​​the opening 201 covered by the cover plate 22 in the closed position is greater than the area of ​​the opening 201 covered by the cover plate 22 in the open position. The support portion 207 is disposed between the first guide groove 2051 and the second guide groove 2052, and the support portion 207 can be exposed through the opening 201 when the cover plate 22 is open.

[0041] Please refer to Figure 5 , Figure 6 and Figure 7 ,in Figure 5 This is a schematic diagram of the support portion of the inverter energy storage device according to an embodiment of the present invention being flipped outwards. Figure 6 This is a schematic diagram of the support portion of the inverter energy storage device according to an embodiment of the present invention abutting against the cover plate. Figure 7 for Figure 6 Enlarged view of section VII in the image.

[0042] When the cover plate 22 is opened by external force, it appears as follows: Figure 3 When the cover plate 22 is in the open state, it is moved to the open position of the guide portion 205, so the support portion 207 is as follows: Figure 3 and Figure 4 The support portion 207 is exposed outside the housing 20, and at this time, it has not yet flipped outward from the inside of the housing 20. Then, when the support portion 207 is subjected to an external force and flips outward, it will present... Figure 5As shown, and assuming that the external force acting on the cover plate 22 disappears, the cover plate 22 will slide down due to gravity and abut against the side of the support portion 207, at which point it will present a state where... Figure 6 and Figure 7 As shown, the cover plate 22 is directly supported by the support part 207. At this time, the opening 201 of the housing 20 will be in an exposed open state to facilitate personnel to carry out any construction or wiring work on the power circuit 10 inside the inverter energy storage device 1 for various transmission lines or components.

[0043] In one embodiment, a wiring transmission section 209 is provided at the bottom of the housing 20. This wiring transmission section 209 may be provided with one or more connectors 2091 as needed. The wiring transmission section 209 communicates with the receiving portion 203 inside the housing 20. The connectors 2091 are for connecting to external transmission lines. That is, the transmission lines can be electrically connected to relevant electronic components (such as power circuits) or transmission interfaces inside the housing 20 via the connectors 2091 to transmit electrical signals. For example, the power circuit 10 is connected to the wiring transmission section 209 for signal transmission.

[0044] In one embodiment, the locking part 208 is disposed on the bottom side of the housing 20. When the cover plate 22 is moved to the closed position, the locking part 208 can lock the cover plate 22 to the housing 20, thereby fixing the cover plate 22 in the closed position and preventing it from moving. When the locking part 208 is released from the cover plate 22, the cover plate 22 can move between the open position and the closed position on the guide part 205 along the guide direction of the guide part 205.

[0045] Furthermore, the locking part 208 includes a first locking member 2081 and a second locking member 2082. The first locking member 2081 is disposed on the first side of the housing 20 and adjacent to the first guide groove 2051, and the second locking member 2082 is disposed on the second side of the housing 20 and adjacent to the second guide groove 2052. The first locking member 2081 and the second locking member 2082 can achieve a locking effect by passing through the housing 20 and the cover plate 22 respectively, preventing the cover plate 22 from moving on the guide part 205. Similarly, the first locking member 2081 and the second locking member 2082 can also achieve an unlocking effect by loosening from the housing 20 and the cover plate 22 respectively, allowing the cover plate 22 to move on the guide part 205.

[0046] In one implementation, the first locking element 2081 and the second locking element 2082 can be screw elements, which can be removable screws or non-removable screws.

[0047] [Example of the support section]

[0048] The implementation status of support unit 207 will be further illustrated with examples below. Please refer to [link / reference]. Figure 8, Figure 9 , Figure 10 and Figure 11 ,in Figure 8 This is a side view of the flipping member of the support portion in the storage position according to an embodiment of the present utility model. Figure 9 This is another schematic diagram of the flipping member of the support portion in the storage position according to an embodiment of the present utility model. Figure 10 This is a side view of the flipping member of the support portion in the support position according to an embodiment of the present utility model. Figure 11 This is another schematic diagram of the flipping member of the support portion in the support position according to an embodiment of the present utility model.

[0049] The structure of the support 207 is described below. In this embodiment, the support 207 includes a flipping member 2071 and a storage member 2073. The flipping member 2071 is pivotally connected to the storage member 2073, meaning that the flipping member 2071 can flip inward to a storage position within the storage member 2073, or the flipping member 2071 can flip outward to a support position outside the storage member 2073. Furthermore, the flipping member 2071 can be fixed to the storage member 2073 via a pivot 2075. When the flipping member 2071 is flipped to the storage position via the pivot 2075, the support surface 20711 of the flipping member 2071 is stored within the storage member 2073, such as... Figure 8 and Figure 9 As shown, at this time, the support part 207 can be regarded as flipping from the outside of the housing 20 into the housing 20 without contacting the cover plate 22, and at this time the support surface 20711 can be as follows: Figure 3 and Figure 4 It does not contact the side of the cover 22 that has been moved to the open position.

[0050] Additionally, when the flipping component 2071 is flipped to the support position via the pivot 2075, the support surface 20711 of the flipping component 2071 protrudes from the storage component 2073, as shown below. Figure 10 and Figure 11 As shown, at this time, the support part 207 can be regarded as flipping from the inside of the housing 20 to the outside of the housing 20 and contacting the cover plate 22, and at this time the support surface 20711 can be as follows: Figure 6 and Figure 7 It contacts one side of the cover 22 that has been moved to the open position.

[0051] In one embodiment, the flipping member 2071 further includes a flipping surface 20713, where the flipping surface 20713 and the supporting surface 20711 are disposed on different sides of the flipping member 2071, and when the flipping member 2071 is flipped to the storage position of the storage member 2073, only the flipping surface 20713 is exposed to the storage member 2073, such as... Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, when the flipping component 2071 is flipped to the supporting position of the storage component 2073, both the supporting surface 20711 and the flipping surface 20713 are exposed outside the storage component 2073, as... Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown. Furthermore, the flipping surface 20713 forms an angle with the supporting surface 20711, and the supporting portion 207 is as follows... Figure 2 The fixed base 206 shown is disposed inside the housing 20. Specifically, the storage part 2073 of the support part 207 is fixedly disposed on the fixed base 206, so that the flipping part 2071 can be flipped in the fixed base 206 position inside the housing 20. Here, the fixed base 206 is adjacent to the side of the opening 201.

[0052] In one embodiment, the storage member 2073 includes a pivot portion 20731, a groove portion 20733, and a fixing piece 20735. The groove portion 20733 connects the pivot portion 20731 and the fixing piece 20735, and the flipping member 2071 is pivotally connected to the pivot portion 20731 via a pivot 2075. The storage member 2073 is fixed to the fixing base 206 by the fixing piece 20735. Therefore, when the flipping member 2071 is flipped to the storage position of the storage member 2073, the flipping member 2071 is stored in the groove portion 20733. When the flipping member 2071 is flipped to the support position of the storage member 2073, the flipping member 2071 is disengaged from the groove portion 20733.

[0053] Please refer to Figure 12 , Figure 12 This is a schematic diagram illustrating the installation of a buffer element in an inverter energy storage device according to an embodiment of the present invention. In this embodiment, a first buffer element 3 is provided at the contact position between the guide portion 205 and the cover plate 22, and a second buffer element 4 is provided on the side of the cover plate 22 facing the interior of the housing 20 and the power circuit 10 (i.e., the side of the receiving portion 203). Thus, when the cover plate 22 moves on the guide portion 205, the friction between the two is reduced by the first buffer element 3, making it easier for the cover plate 22 to move on the guide portion 205. On the other hand, by providing the second buffer element 4, the cover plate 22 can effectively avoid unnecessary wear on the components inside the housing 20 that may be caused when it moves, ensuring the normal operation of the components inside the housing 20.

[0054] In one embodiment, the first buffer 3 may include a first brush layer 31 disposed in the first guide groove 2051 and a second brush layer 32 disposed in the second guide groove 2052, and the second buffer 4 may be a foam layer.

[0055] Therefore, based on the above description, it can be seen that the inverter energy storage device 1 uses the hardware structure of the power control box 2. Thus, for engineers who need to perform wiring work on the inverter energy storage device 1, the first step is to... Figure 1 The locking part 208 shown is released, allowing the cover plate 22 to be moved by a person, and the cover plate 22 is moved to such a position. Figure 3 The first guide position of the guide section 205 is shown. Subsequent engineers can then proceed via... Figure 5 The rotating surface 20713 of the manually rotating support 207 shown faces outward from the housing 20, so that the supporting surface 20711 of the support 207 can rotate outward simultaneously, and as shown... Figure 6 As shown, the support surface 20711 of the support part 207 abuts against one side of the cover plate 22.

[0056] After the cover plate 22 is fixed by the support part 207, the engineer can carry out relevant wiring construction work inside the housing 20 through the opening 201 of the housing 20. After the engineer completes the construction work, the engineer can manually flip the flip surface 20713 of the support part 207 towards the inside of the housing 20. At this time, the cover plate 22 can be moved to the closed position by the guide part 205. Finally, the engineer can fix the cover plate 22 by the locking part 208.

[0057] [Beneficial Effects of the Examples]

[0058] The inverter energy storage device and power control box provided by this utility model are guided by the guide part so that the opening or closing of the cover plate is not limited by the space influence of the external environment of the inverter energy storage device. Furthermore, the flip-out design of the support part can effectively support the cover plate. As a result, the space requirement of the inverter energy storage device can be reduced, and the inverter energy storage device does not require complicated operation during the wiring process, which can better meet the needs of humanization.
