Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage, and specifically provides a household energy storage integrated machine. Background Art

[0002] With the intensification of the global energy crisis and the improvement of environmental awareness, the application of renewable energy (such as solar energy, wind energy, etc.) has gradually received attention. As an important energy storage device, household energy storage devices can store the electricity generated by renewable energy and release it when needed, thereby achieving effective utilization of energy. Traditional household energy storage devices usually only focus on the capacity and performance of energy storage devices in design, and pay relatively little attention to their structural design and installation methods.

[0003] In traditional household energy storage integrated machines, the inverter, as a key component for power conversion, is usually directly installed inside the box of the household energy storage integrated machine and fixed by a simple bracket. This fixing method of the inverter not only has poor stability and is prone to loosening, but also has low utilization of the internal space of the household energy storage integrated machine. Utility Model Content

[0004] One purpose of the utility model is to solve the problem that the inverter of the existing household energy storage integrated machine has low utilization rate of the internal space of the household energy storage integrated machine.

[0005] A further object of the present invention is to solve the problem of poor installation stability of the inverter of the existing household energy storage integrated machine.

[0006] To achieve the above purpose, the utility model provides a household energy storage integrated machine, comprising:

[0007] The inverter box comprises a main body and a protruding portion protruding backward from the main body;

[0008] at least one fixing beam fixedly connected to at least one of the main body and the raised portion, and at least a portion of each fixing beam is located within the raised portion;

[0009] The inverter is arranged in the inverter box and fixedly connected to the fixing beam.

[0010] Optionally, the fixed beam includes a cross beam extending left and right, a longitudinal beam arranged at both ends of the cross beam and extending forward from the cross beam, and a fixing plate arranged at one end of the longitudinal beam away from the cross beam, the cross beam is fixedly connected to the inverter, the fixing plate is fixedly connected to the rear side plate of the main body, and the cross beam and the longitudinal beam are both located in the raised portion.

[0011] Optionally, the longitudinal beam abuts against the side wall of the raised portion in the left-right direction.

[0012] Optionally, the longitudinal beam is provided with an inner folded edge bent toward the transverse beam, so that the cross section of the longitudinal beam is U-shaped.

[0013] Optionally, the crossbeam is provided with an outer folded edge bent toward the rear side thereof, so that the cross section of the crossbeam is U-shaped.

[0014] Optionally, the thickness of the raised portion in the front-to-back direction is selected from between 10 mm and 100 mm; and the ratio of the thickness of the raised portion in the front-to-back direction to the thickness of the main body in the front-to-back direction is selected from between 1 / 5 and 1 / 2.

[0015] Optionally, the thickness of the raised portion in the front-to-back direction is selected from 50 mm to 60 mm; and the ratio of the thickness of the raised portion in the front-to-back direction to the thickness of the main body in the front-to-back direction is selected from 1 / 4 to 1 / 3.

[0016] Optionally, the household energy storage integrated machine further includes a fixing bracket, and the fixing bracket is configured to be fixed to a wall; the fixing bracket is fixedly connected to the raised portion.

[0017] Optionally, the fixing bracket includes a supporting structure and / or at least one fixing structure, the supporting structure abuts against the outer bottom surface of the protrusion; the fixing structure abuts against the outer peripheral surface of the protrusion and is fixedly connected to the protrusion by bolts or screws.

[0018] Optionally, the household energy storage integrated machine also includes a base, a control box and at least one battery pack, the base is arranged on the bottom side of the inverter box, the at least one battery pack and the control box are arranged between the base and the inverter box, and the control box is arranged on the bottom side or top side of the at least one battery pack.

[0019] Based on the foregoing description, those skilled in the art will understand that, in the aforementioned technical solution of the present invention, by providing the inverter box with a main body and a raised portion protruding backward from the main body, and by providing at least a portion of the fixed beam within the raised portion, and by arranging the inverter within the inverter box and fixedly connected to the fixed beam, a portion of the inverter can be located within the raised portion, thereby making the main body of the inverter box flatter in the front-to-back direction, and improving the utilization rate of the inverter in the internal space of the household energy storage machine.

[0020] It is understood by those skilled in the art that since most walls are provided with wall skirts (such as tiles pasted on the bottom of the wall), and household energy storage integrated machines are usually placed against the wall, when the household energy storage integrated machine of the present invention is placed against the wall, the raised portion can overlap with the wall skirt portion in the vertical direction and be hidden by the main body of the inverter box. Compared with the traditional household energy storage integrated machine, the household energy storage integrated machine of the present invention reduces the size of the household energy storage integrated machine after installation at least in the front-to-back direction by locating a part of the inverter in the raised portion, thereby improving the utilization rate of the inverter to the internal space of the household energy storage integrated machine.

[0021] Furthermore, by fixing the cross beam of the fixed beam to the inverter, fixing the fixing plate of the fixed beam to the rear side plate of the main body, and making the cross beam and the longitudinal beam of the fixed beam both located in the raised portion, the longitudinal beam can be used as a cantilever for supporting the inverter, and thus the inverter generates a moment acting on the fixed plate. The moment enables the fixed plate to decompose the force of the inverter into the force in the front-back direction and the force in the up-down direction. Compared with the prior art in which the inverter is fixed by a simple bracket (such as a strip member) and is only subjected to the up-down force, the shear force at the connection between the fixed beam and the inverter box is smaller, and it is less likely to loosen, and the stability of the inverter installation is better.

[0022] Furthermore, by making the longitudinal beam abut against the side wall of the raised portion in the left-right direction, the fixed beam can be restricted from moving by the raised portion when tilting in the left-right direction, thereby ensuring the stability of the fixed beam installation and further ensuring the stability of the inverter installation.

[0023] Furthermore, by providing the longitudinal beam with an inner folded edge bent toward the transverse beam, thereby making the cross section of the longitudinal beam U-shaped, and providing the transverse beam with an outer folded edge bent toward its rear side, thereby making the cross section of the transverse beam U-shaped, the fixed beam of the utility model can be made of metal plates by a bending process, the manufacturing process is simpler and the cost is lower.

[0024] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0043] like Figure 1 As shown, in some embodiments of the present invention, the household energy storage integrated machine 001 includes an inverter module 100, a base 200, a control box 300 and at least one battery pack 400.

[0044] The base 200 is disposed on the bottom side of the inverter module 100. The base 200 is used to support the household energy storage integrated machine 001 on the ground.

[0045] The control box 300 and at least one battery pack 400 are disposed between the base 200 and the inverter module 100 .

[0046] Further, the control box 300 is disposed on the bottom side or the top side of at least one battery pack 400 .

[0047] Specifically, the inverter box 110, at least one battery pack 400, the control box 300 and the base 200 are arranged in sequence from top to bottom.

[0048] In other words, the inverter module 100 , the base 200 , the control box 300 and at least one battery pack 400 are fixed together in a stacked manner to reduce the floor space occupied by the household energy storage integrated machine 001 .

[0049] Refer to the following Figures 2 to 14 To further illustrate the household energy storage integrated machine 001 in some embodiments of the utility model.

[0050] Before that, it should be noted that Figures 2 to 6 The household energy storage integrated machine 001 shown in FIG. 1 has the battery pack 400 hidden, so as to Figure 1 The household energy storage integrated machine 001 shown forms a sharp contrast, so that technical personnel in this field can intuitively understand that the inverter module 100, base 200, control box 300 and battery pack 400 of the utility model exist separately in the form of functional modules and are fixed together in a stacked manner.

[0051] Furthermore, in the present invention, the control box 300 is a highly integrated and intelligent device, which improves the self-sufficiency and economic benefits of household energy use by efficiently managing and dispatching electric energy, and also provides users with a convenient operation and maintenance experience. Functional modules such as a battery management system (BMS) and an energy management system (EMS) may be integrated in the control box 300.

[0052] Since the control box 300 is a conventional device in the art and is well known to those skilled in the art, the present invention will not describe it in detail.

[0053] like Figures 2 to 6 As shown, in some embodiments of the utility model, the household energy storage integrated machine 001 also includes a fixing bracket 500, which is fixedly connected to the inverter module 100 and is used to be fixed to the wall 002, so as to fix the household energy storage integrated machine 001 to the wall 002, prevent the household energy storage integrated machine 001 from tipping over, and ensure the stability of the household energy storage integrated machine 001 during use.

[0054] like Figures 2 to 8 As shown, the inverter module 100 includes an inverter box 110 , a door 120 , an inverter 130 , a supporting device 140 and a fixing beam 150 .

[0055] The door body 120 is installed on the inverter housing 110 to open and cover the inverter housing 110. The inverter 130 is arranged in the inverter housing 110. One end of the support device 140 is connected to the inverter housing 110, and the other end of the support device 140 is connected to the door body 120. The support device 140 is used to support the fully opened door body 120. The fixing beam 150 is fixedly connected to the inverter housing 110 and is used to fix the inverter 130, so as to fix the inverter 130 in the inverter housing 110.

[0056] In addition, in other embodiments of the present invention, those skilled in the art may also omit at least one of the supporting device 140 and the fixing beam 150 as needed.

[0057] like Figures 2 to 8 As shown, in some embodiments of the present invention, a plurality of heat dissipation holes 1101 are provided on the inverter box 110 to dissipate heat from the inverter 130 through the plurality of heat dissipation holes 1101 to prevent the operating temperature of the inverter 130 from being too high and affecting the working efficiency of the inverter 130 .

[0058] like Figure 7 As shown, in some embodiments of the present invention, the inverter box 110 is provided with a front opening 1102 , so that the inverter 130 , the supporting device 140 and the fixing beam 150 can be installed in the inverter box 110 through the front opening 1102 .

[0059] like Figures 2 to 8 As shown, in some embodiments of the present invention, the door body 120 is pivotally connected to the inverter box 110 through its top end, so that the door body 120 opens the front opening 1102 in an upward manner.

[0060] Optionally, a hinge (not marked in the figure) is provided between the top end of the door body 120 and the inverter box body 110, so that the door body 120 and the inverter box body 110 are pivotally connected together through the hinge.

[0061] like Figures 2 to 8 As shown, in some embodiments of the present invention, the inverter box 110 includes a main body 111 and a protruding portion 112 protruding backward from the main body 111 .

[0062] A plurality of heat dissipation holes 1101 are arranged on the peripheral wall of the protruding portion 112. Specifically, a plurality of heat dissipation holes 1101 are arranged on the top side, the bottom side, the left side and the right side of the protruding portion 112.

[0063] It is understood by those skilled in the art that the heat dissipation holes 1101 of the raised portion 112 make it easy for the raised portion 112 to form convection in the up-down direction and the left-right direction, so that air flows into and out of the raised portion 112 through the heat dissipation holes 1101. By locating a part of the inverter 130 in the raised portion 112, the inverter 130 can dissipate heat naturally through the convective air in the raised portion 112, thereby ensuring the heat dissipation effect of the inverter 130. In particular, compared with only providing the heat dissipation holes 1101 on at least one of the left side, right side, top side and rear side of the inverter housing 110, the heat dissipation holes 1101 provided on the peripheral wall of the raised portion 112 of the utility model have a better heat dissipation effect on the inverter 130.

[0064] Furthermore, a plurality of heat dissipation holes 1101 are also provided on the top side of the main body 111 to increase the convection effect when the inverter 130 dissipates heat. Specifically, a portion of the hot air around the inverter 130 can be discharged from the inverter case 110 through the heat dissipation holes 1101 on the top side of the main body 111, thereby preventing the hot air from accumulating in the inverter case 110 and affecting the heat dissipation effect of the inverter 130.

[0065] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, an opening 1103 is provided on a side of the protrusion 112 away from the main body 111 .

[0066] It is understood by those skilled in the art that by providing the opening 1103 on the side of the protrusion 112 away from the main body 111 , the heat dissipation area of ​​the inverter 130 is increased, and the heat dissipation effect of the inverter 130 is further improved.

[0067] like Figure 3 As shown, in some embodiments of the present invention, the fixing bracket 500 is fixedly connected to the protruding portion 112 .

[0068] like Figure 6 As shown, when the fixing bracket 500 is mounted on the wall 002 , a gap 004 is formed between the protrusion 112 and the wall 002 to allow air to enter and exit the opening 1103 through the gap 004 .

[0069] At the same time, a gap 004 is formed between the control box 300 and the wall 002 to prevent the base 200 from interfering with the wall skirt 003 (such as tiles) when the fixing bracket 500 is installed on the wall 002.

[0070] Those skilled in the art will appreciate that by forming a gap 004 between the raised portion 112 and the wall 002 , air can enter and exit the opening 1103 through the gap 004 , forming an airflow to cool the inverter 130 , further improving the heat dissipation effect of the inverter 130 .

[0071] Continue reading Figure 6 In some embodiments of the present invention, the thickness D1 of the protrusion 112 in the front-to-back direction is selected from 10 mm to 100 mm; and the ratio of the thickness D1 of the protrusion 112 in the front-to-back direction to the thickness D2 of the main body 111 in the front-to-back direction is selected from 1 / 5 to 1 / 2.

[0072] Furthermore, the thickness D1 of the protrusion 112 in the front-to-back direction is selected between 50 mm and 60 mm; and the ratio of the thickness D1 of the protrusion 112 in the front-to-back direction to the thickness D2 of the main body 111 in the front-to-back direction is selected between 1 / 4 and 1 / 3.

[0073] For example, the thickness D1 of the protrusion 112 in the front-to-back direction can be any feasible value such as 10mm, 40mm, 45mm, 50mm, 58.8mm, 85mm, etc. The thickness D2 of the body 111 in the front-to-back direction can be any feasible value such as 100mm, 155mm, 187mm, 200mm, etc.

[0074] like Figure 2 , Figure 3 , Figures 6 to 8 As shown, in some embodiments of the present invention, the cross section of the protrusion 112 perpendicular to the first direction is smaller than the cross section of the body 111 perpendicular to the first direction, so that the body 111 covers the protrusion 112 and the fixing bracket 500 .

[0075] The first direction is parallel to the front-to-back direction of the inverter housing 110 .

[0076] Those skilled in the art can understand that by making the cross-section of the protrusion 112 perpendicular to the first direction smaller than the cross-section of the main body 111 perpendicular to the first direction, the main body 111 can cover the protrusion 112 and the fixing bracket 500, thereby ensuring the aesthetics of the household energy storage integrated machine 001.

[0077] like Figure 7 As shown, in some embodiments of the present invention, a front protrusion 113 is provided at the bottom of the inverter box 110 , and the front protrusion 113 is matched with the bottom of the door body 120 .

[0078] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, a rear protrusion 121 is provided at the circumferential edge of the door body 120 , and the rear protrusion 121 is adapted to the left and right panels of the inverter box body 110 to ensure that the door body 120 covers the front opening 1102 .

[0079] It will be understood by those skilled in the art that by providing a front protrusion 113 at the bottom of the inverter case 110 that matches the bottom of the door body 120, and providing a rear protrusion 121 at the circumferential edge of the door body 120 that matches the left and right panels of the inverter case 110, the front portion of the inverter case 110 is concave as a whole, thereby preventing the left and right panels of the inverter case 110 from affecting the operator's line of sight when observing the internal conditions of the inverter case 110.

[0080] Continue reading Figure 7 and Figure 8 In some embodiments of the present invention, rear convex portions 121 are distributed on the left edge, right edge and top edge of the door body 120 to increase the operator's field of vision for observing the internal conditions of the inverter box 110 .

[0081] Continue reading Figure 7 and Figure 8 In some embodiments of the present invention, a sink groove 1111 is provided in at least one of the left side plate and the right side plate of the inverter box 110. The rear protrusion 121 of the door body 120 blocks a part of the sink groove 1111, so that the operator can hook the rear protrusion 121 through the sink groove 1111 and thus open the door body 120.

[0082] Continue reading Figure 7 and Figure 8 In some embodiments of the present invention, at least one of the left and right plates of the inverter housing 110 is provided with an internal thread structure 1131. The rear protrusion 121 is provided with a side through hole 1201 corresponding to the internal thread structure 1131, so that the bolt 610 or the screw 620 passes through the side through hole 1201 and is tightened into the internal thread structure 1131.

[0083] It can be understood by those skilled in the art that the above-mentioned fixing method of the door body 120 and the inverter box body 110 can effectively prevent the user from opening the door body 120, thereby ensuring the personal safety of the user.

[0084] like Figure 7 As shown, in some embodiments of the present invention, the supporting device 140 includes a first connecting seat 1411 , a second connecting seat 1412 , a first connecting rod 1421 , and a second connecting rod 1422 .

[0085] The first connection base 1411 is fixedly connected to the inverter box 110. For example, the first connection base 1411 and the inverter box 110 can be fixedly connected together by bolts 610 or screws 620, or can be riveted together, or can be welded together.

[0086] The second connecting seat 1412 is fixedly connected to the door body 120 .

[0087] Exemplarily, the second connection seat 1412 and the door body 120 may be fixedly connected together by bolts 610 or screws 620, or may be riveted together, or may be welded together.

[0088] One end of the first connecting rod 1421 is rotatably connected to the first connecting seat 1411 , the other end of the first connecting rod 1421 is rotatably connected to one end of the second connecting rod 1422 , and the other end of the second connecting rod 1422 is rotatably connected to the second connecting seat 1412 .

[0089] Furthermore, a stop structure (not marked in the figure) is provided on one of the first connecting rod 1421 and the second connecting rod 1422, so that when the door body 120 is fully opened and the first connecting rod 1421 and the second connecting rod 1422 are substantially parallel, the first connecting rod 1421 and the second connecting rod 1422 are abutted by the stop structure, thereby preventing the first connecting rod 1421 and the second connecting rod 1422 from continuing to rotate relative to each other.

[0090] It should be noted that, since the supporting device 140 in some embodiments of the present invention is a conventional supporting device 140 and is well known to those skilled in the art, it will not be described in detail here.

[0091] In addition, in other embodiments of the present invention, those skilled in the art may also configure the supporting device 140 to be any other feasible structure, such as a telescopic rod, as required.

[0092] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the fixing beam 150 is fixedly connected to at least one of the body portion 111 and the raised portion 112 , and at least a portion of each fixing beam 150 is located in the raised portion 112 .

[0093] It should be noted that, in the present invention, the number of the fixed beams 150 is not limited to Figure 7 and Figure 8 Although two are shown in FIG. 1 , it can also be any other feasible number. For example, the number of the fixing beams 150 can be one, three, four, etc.

[0094] like Fig. 9 and Fig.10As shown, in some embodiments of the present invention, the fixed beam 150 includes a horizontal beam 151 extending left and right, a longitudinal beam 152 provided at both ends of the horizontal beam 151 and extending forward from the horizontal beam 151, and a fixing plate 153 provided at one end of the longitudinal beam 152 away from the horizontal beam 151. The horizontal beam 151 is fixedly connected to the inverter 130, the fixing plate 153 is fixedly connected to the rear side plate of the body 111, and both the horizontal beam 151 and the longitudinal beam 152 are located in the raised portion 112.

[0095] It is understood by those skilled in the art that, by making the cross beam 151 of the fixed beam 150 fixedly connected to the inverter 130, making the fixing plate 153 of the fixed beam 150 fixedly connected to the rear side plate of the main body 111, making the cross beam 151 and the longitudinal beam 152 of the fixed beam 150 both located in the raised portion 112, the longitudinal beam 152 can be used as a cantilever for supporting the inverter 130, and thus the inverter 130 generates a moment acting on the fixing plate 153. The moment enables the fixing plate 153 to decompose the force of the inverter 130 into the force in the front-back direction and the force in the up-down direction. Compared with the prior art in which the inverter 130 is fixed by a simple bracket (such as a strip member) and is only subjected to the up-down force, the shear force at the connection between the fixed beam 150 and the inverter 130 box is smaller, and it is less likely to be loose, and the inverter 130 is installed with better stability.

[0096] Furthermore, although not explicitly shown in the figures, in some embodiments of the present invention, the longitudinal beam 152 can abut against the side walls of the protrusion 112 in the left and right directions, so that when the fixed beam 150 tilts in the left and right directions, it can be restricted from moving by the protrusion 112, thereby ensuring the stability of the installation of the fixed beam 150, and further ensuring the stability of the installation of the inverter 130.

[0097] Continue reading Fig. 9 and Fig.10 In some embodiments of the present invention, the longitudinal beam 152 is provided with an inner folded edge 1521 bent toward the cross beam 151, so that the cross section of the longitudinal beam 152 is U-shaped.
