[0044] One of the first bracket 3 and the second bracket 4 is provided with the positioning member 5, and the other is provided with the mounting hole 43 extending along the first preset direction X. In this embodiment, the positioning member 5 is preferably arranged on the first bracket 3, and the mounting hole 43 is arranged on the second bracket 4, which will be described below as an example, but is not limited thereto. The positioning member 5 can be arranged on the second bracket 4, and the mounting hole 43 can be arranged on the first bracket 3 according to actual needs.

[0045] The positioning member 5 can be inserted into the mounting hole 43 along the second preset direction Z, and the positioning member 5 can slide along the first preset direction X in the mounting hole 43, so that the box cover 2 moves relative to the box body 1 and can still be hung on the box body 1.

[0046] According to the above-described structure, the mounting box provided by the present application can be applied to the energy storage inverter. When the display screen 10 and other structures on the box cover 2 need to be maintained or the internal structure of the box body 1 needs to be maintained, and then the box cover 2 is disassembled, the positioning member 5 on the first bracket 3 on the cover plate 21 can only move along the first preset direction X in the mounting hole 43 on the second bracket 4 on the box body 1 at the moment when the sealing ring 9 pops open the cover plate 21, so that the box cover 2 can still be hung on the box body 1, thereby preventing the box cover 2 from falling to the ground or hitting the operator, and preventing the box cover 2 and the display screen 10 and other structures thereon from being damaged. On this basis, there is no need for multiple people to work together to prevent the cover plate 21 from falling, which is more time-saving and labor-saving, and greatly saves labor costs.

[0047] Further, the first preset direction X described above can be the width direction of the mounting box, i.e., the thickness direction, but is not limited thereto, and can be selected according to actual needs.

[0048] It should be noted that the mounting box provided by the present application is not limited to being applied to the energy storage inverter, but can also be applied to other devices according to actual needs.

[0051] According to the above-described structure, it is known that the mounting hole 43 on the second bracket 4 is designed as a special-shaped hole, that is, composed of a strip-shaped hole and another hole with a width greater than the strip-shaped hole, and then after the fastening bolts 8 on the box cover 2 and the box body 1 are disassembled, under the elastic force of the sealing ring 9, the positioning member 5 on the first bracket 3 can only move along the first hole portion 431, but cannot be separated from the first hole portion 431, and then the box cover 2 can be manually moved to the position of the second hole portion 432, and the sliding portion 51 and the limiting portion 52 of the positioning member 5 are sequentially moved out of the second hole portion 432 along the second preset direction Z, so that the box cover 2 is completely separated from the box body 1. The above operation is simple and convenient, and can be completed by one worker, saving time and effort.

[0052] Further, preferably, the second preset direction Z is the height direction of the box body 1, for example, the vertical direction, of course, not only limited to this, the second preset direction Z can also be the horizontal direction, which is selected according to actual needs.

[0053] Further, preferably, the positioning member 5 further comprises a connecting portion 53, and the connecting portion 53 is connected with one end of the sliding portion 51 away from the limiting portion 52, and preferably, a through hole is formed on the first support plate 32 of the first bracket 3, and the connecting portion 53 is installed in the through hole and fixedly connected with the through hole, and preferably, the connecting portion 53 and the through hole can be connected by interference fit, gluing or welding, etc.

[0054] Further, preferably, in actual use, along the second preset direction Z, for example, the vertical direction, the limiting portion 52 is arranged above the mounting hole 43, of course, not only limited to this, but also can be located below the mounting hole 43, which is selected according to actual needs.

[0055] In this embodiment, preferably, as shown in Figure 3 and Figure 8 , the first bracket 3 comprises a first mounting plate 31 and a first support plate 32 connected with each other and forming an L-shaped structure; the first mounting plate 31 is installed on the box cover 2 and arranged along the height direction of the box cover 2, and the first support plate 32 extends towards the direction of the box body 1.

[0056] According to the above-described structure, the first support 3 is arranged in an L-shaped structure, the first mounting plate 31 of which is connectable with the box cover 2, and the first support plate 32 of which is used for mounting the positioning member 5, and the positioning member 5 is introduced to the horizontally arranged second support plate 42 described below, facilitating the assembly of the positioning member 5 and the mounting hole 43 on the second support plate 42, that is, the L-shaped first support 3 can change the mounting orientation, improving the assembly and convenience, and the structure is simple and convenient for processing and manufacturing.

[0057] Of course, the structure of the first support 3 is not limited to the above.

[0058] In this embodiment, preferably, as shown in Figure 5 and Figure 8 , the second support 4 includes a second mounting plate 41 and a second support plate 42 connected with each other and arranged in an L-shaped structure; the second mounting plate 41 is mounted on the box body 1 and arranged along the height direction of the box body 1, and the second support plate 42 extends towards the direction of the box cover 2;

[0059] The positioning member 5 is arranged on one of the first support plate 32 and the second support plate 42, and the mounting hole 43 is arranged on the other one of the first support plate 32 and the second support plate 42, and the second support plate 42 is arranged above the first support plate 32 along the second preset direction Z.

[0060] According to the above-described structure, the second support 4 is arranged in an L-shaped structure, the second mounting plate 41 of which is connectable with the box body 1, and the first support plate 32 of which is used for arranging the mounting hole 43, and the mounting hole 43 is introduced below the vertically arranged positioning member 5 described above, facilitating the assembly with the positioning member 5, that is, the L-shaped second support 4 can change the mounting orientation, improving the assembly and convenience, and the structure is simple and convenient for processing and manufacturing.

[0061] In this embodiment, preferably, as shown in Figure 5 and Figure 8 , the mounting box further includes a first mounting member 6 and a second mounting member 7; wherein the box cover 2 is formed with a first mounting through hole 61 penetrating through both sides thereof along the first preset direction X, and the first mounting member 6 is mounted in the mounting through hole; the second mounting member 7 is mounted on the box body 1, and the second mounting member 7 is formed with a threaded hole;

[0062] The first mounting member 6 is formed with a second mounting through hole penetrating through both sides thereof along the first preset direction X, and the inner wall of the second mounting through hole is formed with a limiting protrusion 62, and it can be seen that the limiting protrusion 62 divides the inner part of the second mounting through hole into two parts, i.e., an outer hole part 64 and an inner hole part 63; the second mounting member 7 can be inserted into the first mounting member 6 and abut against the limiting protrusion 62, and the threaded hole and the first mounting through hole 61 are arranged correspondingly;

[0063] The mounting box also includes fastening bolts 8, and the studs of the fastening bolts 8 can lock the second mounting member 7 and the box body 1 via the first mounting member 6.

[0064] As can be seen from the structure described above, the press-fit component is designed as a split structure, with one part, namely the first mounting component 6, set on the cover 2, and the other part set on the box body 1, protruding from the box body 1. When the box body 1 and the cover 2 are assembled, the limiting protrusion 62 protruding from the box body 1 can be inserted into the inner hole 63 of the first mounting component 6 and abut against the limiting protrusion 62, ensuring that the outer hole 64 and the threaded hole on the second mounting component 7 are exactly aligned. In this way, no deviation will occur when installing the fastening bolt 8, improving assembly efficiency and accuracy.

[0065] It should be noted that the threaded hole on the aforementioned second mounting component 7 can be a through hole that extends through both ends along the first preset direction X, or it can be a blind hole that extends only through the side near the cover 2 along the first preset direction X. In this way, when the fastening bolt 8 is installed, the closed end can be forced to open and connected to the housing 1. Of course, it is not limited to this and can be designed according to actual needs.

[0066] In this embodiment, preferably, as follows: Figure 4 As shown, the box cover 2 includes a cover plate 21 and a box cover flange 22; wherein, the box cover flange 22 is formed on the edge of the cover plate 21 and extends along the entire circumference of the cover plate 21, and the box cover flange 22 and the cover plate 21 form a concave cavity; the first bracket 3 is disposed on the cover plate 21 and is located inside the box cover flange 22, that is, inside the concave cavity.

[0067] As can be seen from the structure described above, the cover flange 22 and the cover plate 21 form a concave cavity structure, which is used to accommodate the first support 3 and avoid the sealing ring 9 described below.

[0068] Furthermore, preferably, the lid flange 22 is perpendicular to the cover plate 21, and the lid flange 22 and the cover plate 21 form a cavity. Of course, it is not limited to this; the lid flange 22 may also form an obtuse angle or an acute angle with the cover plate 21.

[0069] In this embodiment, preferably, as follows: Figure 4 As shown, the box 1 has an opening, and a box flange 11 is formed on the side of the opening. The second bracket 4 is disposed on the box flange 11; the cover plate 21 covers the opening of the box 1.

[0070] As can be seen from the structure described above, a box flange 11 is provided at the edge of the opening, providing an installation position for the second bracket 4.

[0071] Further, preferably, the box flange 11 and the box 1 can be in an integral structure, of course, not limited to this, but also can be in a split structure, connected by welding or the like.

[0072] Further, preferably, the box flange 11 is arranged perpendicularly to the side wall of the opening of the box 1, of course, not limited to this, the box flange 11 forms an obtuse angle or an acute angle with the side wall of the opening of the box 1.

[0073] In this embodiment, preferably, as shown in Figure 2 and Figure 4 , the mounting box further comprises a sealing ring 9, and the circumferential edge of the opening of the box 1 is formed with a mounting protrusion 12 extending towards the side of the box cover 2, and it can be seen that the mounting protrusion 12 is annular; the sealing ring 9 can be sleeved on the mounting protrusion 12, and the sealing ring 9 can be compressed between the cover plate 21 and the box flange 11.

[0074] According to the structure described above, the sealing ring 9 is compressed between the cover plate 21 and the box flange 11, which plays a sealing role, and the sealing ring 9 can be sleeved on the mounting protrusion 12 of the circumferential edge of the opening of the box 1, so that the sealing ring 9 will not be displaced.

[0075] In this embodiment, preferably, as shown in Figure 1 , the mounting box further comprises a display screen 10, and the display screen 10 is arranged on the cover plate 21, which can facilitate users to read and adjust the performance parameters of the energy storage inverter and the like.

[0076] In summary, the mounting and dismounting process between the box 1 and the box cover 2 of the mounting box provided by the present application is as follows: (1) the installation steps are as follows:

[0077] First, the limiting portion 52, i.e. the large end of the positioning member 5 on the cover plate 21 is inserted into the second hole portion 432, i.e. the large hole of the special-shaped hole, and extends upwards or downwards through the large hole, at this time the sliding portion 51 can slide along the second hole portion 432 and the first hole portion 431, and then the box cover 2 is pressed towards the box 1, the sliding portion 51 slides from the second hole portion 432 into the first hole portion 431, thereby limiting the sliding portion 51 in the X direction and the Z direction, and only moving in the Y direction, i.e. the third preset direction Y, when the limiting protrusion 62 in the first mounting member 6 contacts the second mounting member 7 on the box 1, the sealing ring 9 reaches the appropriate compression amount, and then the fastening bolt 8 is installed to lock the box cover 2 and the box 1.

[0078] Among them, the third preset direction Y can be the length direction of the mounting box, of course, not limited to this, but also can be selected according to actual needs.

[0079] (2) the dismounting steps are as follows:

[0080] Loosen the fastening bolt 8, due to the elasticity of the sealing ring 9, the box cover 2 will be opened, but due to the cooperation of the special-shaped hole and the positioning member 5, the positioning member 5 can only move in the Y-axis direction, and cannot move in the X direction and the Z direction, so that the cover plate 21 will not directly fall off or hit the operator, which is more safe and reliable.

[0081] It can be seen that the box cover 2 of the mounting box provided by the application will not be opened by the sealing ring 9 during disassembly, but will directly fall off or hit the operator, which is more safe and reliable, and thus the disassembly process does not require multiple people to cooperate, and only one person can complete it, saving time and effort.

[0082] Embodiment two

[0083] The mounting box in this embodiment is an improvement based on embodiment one, and the technical content disclosed in embodiment one will not be repeated. The content disclosed in embodiment one also belongs to the content disclosed in this embodiment.

[0084] The difference between the mounting box provided by this embodiment and the mounting box provided by embodiment one is that when the first support 3 is provided with the positioning member 5, the positioning member 5 is detachably connected with the first support 3, for example, can adopt a plug-in mode, that is, the first support 3 is provided with a round hole, and the positioning member 5 such as a pin can be detachably inserted into the round hole. Of course, the positioning member 5 is not limited to a pin, but can also be other structures. In addition, it should be noted that the positioning member 5 and the first support 3 can also adopt a clamping or bolt detachable connection mode.

[0085] Then in this case, when the box cover 2 and the box body 1 are assembled and disassembled, when the fastening bolt 8 between the two is disassembled, the moment when the locking force between the box cover 2 and the box body 1 is lost, the box cover 2 moves away from the box body 1, that is, can only move in the Y direction, and cannot move in the X direction and the Z direction, thereby making the box cover 2 hang on the box body 1, so that the box cover 2 will not fall to the ground, thereby preventing damage to the box cover 2 and the display screen 10 and other structures thereon, and without the need for multiple people to work together to prevent the cover plate 21 from falling, it is more time-saving and labor-saving, greatly saving labor costs.

[0086] When it is necessary to completely disassemble the box cover 2 from the box body 1, the user only needs to support the box cover 2 with one hand or the body, and pull out the positioning member 5 from the round hole and the mounting hole 43 with the other hand, which is simple and convenient to operate.

[0087] It should be noted that when the second support 4 is provided with the positioning member 5, the positioning member 5 is detachably connected with the second support 4, for example, the positioning member 5 can be in the form of plug-in, that is, the second support 4 is provided with a round hole, and the positioning member 5 such as a pin is detachably inserted in the round hole, of course, the positioning member 5 is not limited to the pin, but can also be other structures, in addition, it should be noted that the positioning member 5 and the first support 3 can also be detachably connected in the form of clamping or bolt.

[0088] Embodiment three

[0089] The embodiment three of the present application also provides an energy storage inverter, which comprises the mounting box of the above-mentioned embodiment one or embodiment two, thus, has all the beneficial technical effects of the mounting box, and the same technical features and beneficial effects will not be described herein.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
