[0030] Cabinet 10, the cabinet 10 is equipped with frame assembly 11, the frame assembly 11 is equipped with installation cavity 12 and the opening 13 communicated with the installation cavity 12;

[0031] Inverter mounting bracket 20, in the installation cavity 12, the inverter mounting bracket 20 is connected to the frame assembly 11;

[0032] Inverter structure 30, in the installation cavity 12, the inverter structure 30 is correspondingly set at the opening 13, the inverter structure 30 is detachably connected with the inverter mounting bracket 20, to make the inverter structure 30 can be moved into or moved out the installation cavity 12 by the opening 13.

[0033] The utility model scheme cabinet body 10, this is the whole system's shell, it not only provides a closed space for internal component, also protects the internal electronic equipment from the influence of outside environment. Cabinet body 10 includes frame assembly 11, and frame assembly provides structural support, and forms an installation cavity 12 for accommodating inverter and other related components. Frame assembly 11 as a part of cabinet body 10, frame assembly 11 defines the boundary of installation cavity 12, and is equipped with an opening 13. This opening allows technicians to access the internal inverter structure 30 without completely disassembling the cabinet. Inverter mounting rack 20 is fixed in installation cavity 12 and is connected with frame assembly 11, and inverter mounting rack 20 is the support for supporting inverter structure 30. Inverter structure 30 can be conveniently connected or disconnected with mounting rack 20 through opening 13. This detachable design makes the inverter easily move in or out of installation cavity 12, so as to facilitate installation, maintenance or replacement. The detachable connection between inverter structure 30 and inverter mounting rack 20 is detachable, and such design simplifies the installation process of inverter, reduces the time and complexity of on-site operation. Since inverter structure 30 is detachably connected to mounting rack 20, the operator can conveniently move the inverter out of or into installation cavity 12, simplifying the installation process and making maintenance and replacement more convenient and fast. The design scheme allows the entire inverter to be handled as a module, which not only helps to realize the miniaturization and compact layout of the device, but also can support rapid deployment and flexible configuration. The design of opening 13 can promote air circulation, thereby helping the inverter to dissipate heat better, which is very important for ensuring the long-term stable operation of the inverter.

[0034] Referring to Figs. 1-3 In the utility model embodiment, the inverter structure 30 includes a plurality of inverters 31, and the plurality of inverters 31 are arranged at intervals along a first direction. The inverter mounting rack 20 includes a rack body 21 and a plurality of hangers 22. The rack body 21 is connected with the frame assembly 11, and the plurality of hangers 22 are arranged at intervals on the rack body 21 along the first direction. Each inverter 31 is detachably connected with each hanger 22.

[0035] The plurality of inverters 31 are arranged at intervals along a first direction, that is, a plurality of independent inverter units (inverters 31) can be accommodated in one inverter structure 30, and the inverters are arranged along a specific direction (such as a vertical or horizontal direction) and kept at intervals. In the present scheme, the inverter mounting rack 20 is composed of two main parts, the rack body 21 and the hanging piece 22. The rack body 21 is fixed on the frame assembly 11, and the hanging piece 22 is distributed on the rack body 21 along the same "first direction" as the inverter 31, providing a separate connection point for each inverter 31. Each inverter 31 can be individually connected to the corresponding hanging piece 22, and this connection can be easily removed, that is, the inverter 31 can be removed or installed on the hanging piece 22. Since the inverter 31 is connected to the inverter mounting rack 20 through the hanging piece 22, the technician can quickly install or remove a single inverter from the system without disturbing other inverters 31, which greatly simplifies installation and improves maintenance convenience. This design allows the number of inverters 31 to be increased or decreased as needed. Users can flexibly adjust the system capacity according to actual needs without the need for large-scale changes to the entire system. The spacing between the plurality of inverters 31 helps to improve air circulation and promote heat dissipation, thereby avoiding performance degradation or failure due to overheating. Each inverter 31 corresponds to a hanging piece 22, and each inverter 31 has its own fixed electrical connection point, which can simplify wiring, reduce the risk of incorrect connection, and make the connection clearer and more orderly. By ensuring that each inverter 31 is securely mounted on its corresponding hanging piece, the risk of loosening or falling due to vibration or other external forces is reduced, improving the overall stability of the system.

[0036] With reference to Figs. 1-3 In the embodiment of the utility model, the hanging piece 22 includes a hanging piece body 221 and a slide rail, the hanging piece body 221 is connected with the rack body 21, the slide rail is arranged on the hanging piece body 221 and extends along the first direction, and the inverter 21 is connected with the slide rail in a sliding mode, so that the inverter 21 can be moved into or out of the mounting cavity 12 through the opening 13 by sliding along the first direction.

[0037] Each hanger 22 is composed of two parts - a hanger body 221 and a slide rail. The hanger body 221 is connected to the rack body 21 of the inverter mounting rack 20, providing structural support. The slide rail is arranged on the hanger body 221 and extends in the "first direction" (i.e. the direction of inverter arrangement). The connection between the inverter 31 and the slide rail: the inverter 31 and the slide rail are connected in a sliding manner, that is, the inverter 31 can move along the slide rail in the first direction. The inverter 31 can be easily moved into or out of the mounting cavity 12 through the opening 13 on the cabinet body 10. The design of the slide rail makes the installation and removal of the inverter 31 more intuitive and simple. The technician only needs to push or pull the inverter 31 to complete the installation or removal work, without complex disassembly steps. Traditional inverter installation may require a larger operating space to accommodate tools and personnel activities. After using the slide rail, the inverter 31 can easily enter and exit in a limited space, reducing the need for external space. The slide rail mechanism ensures controlled movement of the inverter 31 during installation and removal, avoiding physical damage caused by improper handling. The slide rail system allows quick addition or removal of inverter units as needed, enhancing the scalability of the system. Users can flexibly adjust the number and configuration of inverters 31 according to actual needs without redesigning the entire system layout. The design of the slide rail not only facilitates the installation and removal of the inverter 31, but also promotes air circulation, helping the inverter to dissipate heat better, especially in the case of multiple inverters arranged densely. The slide rail provides stable mechanical guidance, ensuring the positional accuracy of the inverter 31 during installation and removal, reducing the risk of accidental dropping or other safety incidents. It can be understood that the hanger body 221 can be in the form of a slide rail or track, allowing the inverter 21 to slide into place along the first direction; it can also be an L-shaped hanger body composed of two perpendicular intersecting plates, one plate is fixed to the rack body 21, and the other plate is used to support the inverter 21 with a slide rail; it can also be composed of multiple small hanger units that can be combined together, each unit can be installed or removed individually and equipped with a slide rail.

[0038] Referring to Figs. 1-3 In the embodiment of the utility model, the hanger 22 includes a hanger body 221 and a locking member, the hanger body 221 is connected with the rack body 21, the locking member is arranged on the hanger body 221 and extends in the first direction, and the inverter 21 is detachably connected with the locking member, so that the inverter 21 can be moved into or out of the mounting cavity 12 through the opening 13.

[0039] The hanger body 221 is connected to the rack body 21 of the inverter mounting rack 20, providing structural support. The locking member is arranged on the hanger body 221 along the "first direction" (i.e. the direction of inverter arrangement). The design of the locking member allows the inverter 31 to be detachably connected thereto. The inverter 31 is detachably connected to the hanger 22 through the locking member, that is, the inverter can be easily installed or removed without damaging any permanent connection. Since the inverter 31 can be quickly connected or disconnected with the locking member, the inverter can be conveniently moved into or out of the mounting cavity 12 through the opening 13 on the cabinet body 10. The design of the locking member simplifies the installation and removal process of the inverter 31. The technician only needs to operate the locking member to complete the fixation or release of the inverter 31, greatly reducing the installation time and complexity. The locking member provides reliable mechanical fixation, ensuring that the inverter 31 will not accidentally loosen or fall off during operation, improving the overall safety of the system. Especially in a vibrating environment, this locking mechanism is particularly important. The locking member makes the installation and removal of the inverter 31 very convenient, and users can flexibly adjust the number and configuration of inverters according to actual needs, enhancing the scalability of the system. By using a specially designed locking member, physical damage caused by improper operation can be avoided, ensuring that the inverter 31 is properly protected during transportation and installation. When a single inverter 31 needs to be debugged or repaired, the locking member allows the technician to quickly remove the target inverter 31 without affecting other units, improving work efficiency. By introducing the locking member, this scheme not only simplifies the installation and removal process of the inverter, but also improves the safety, reliability and maintainability of the system. It can be understood that the locking member can be a quick release lock, a bolt type locking member, a clasp spring or a spring loaded push rod. It can be understood that the hanger body 221 is composed of one or more hook-shaped components, and the inverter can be directly hung on these hooks and further fixed by the locking member; it can also be a flat metal plate with reinforcing ribs to improve strength, usually with holes for fixing to the rack body 21, and provided with a locking member; it can also be composed of multiple small hanger units that can be combined together, each unit can be installed or removed individually and equipped with a locking member.

[0040] Referring to Figs. 1-3 In the embodiments of the present application, the inverter mounting rack 20 further comprises a plurality of limiting members 23, each of which is connected to each of the hangers 22, and the limiting space is defined between the adjacent two limiting members 33, and the inverter 31 is arranged in the limiting space.

[0041] A plurality of limiters 23 are added in the inverter mounting rack 20, each of which is connected with a corresponding hanging piece 22. Adjacent two limiters 23 define a limiting space for accommodating a single inverter 31. Each inverter 31 is placed in the limiting space formed by the adjacent limiters 23, ensuring its position is fixed and protected. The limiters 23 provide a clear mounting position for each inverter 31, ensuring they can be installed according to the predetermined position, reducing installation errors and improving installation consistency and accuracy. The design of the limiters 23 simplifies the installation process of the inverters, and technicians only need to place the inverters 31 into the corresponding limiting space to complete the preliminary positioning without additional adjustments. The limiting space effectively limits the movement or shaking of the inverters 31 in the installation cavity 12, especially when the device is transported or in operation and encounters vibration, enhancing the overall stability of the system. The limiters 23 provide a physical barrier for the inverters 31, reducing the likelihood of damage due to accidental collisions or other external factors. By separating the individual inverters 31 with limiters 23, a more uniform air flow path can be provided around each inverter 31, helping to improve heat dissipation efficiency and reduce the risk of overheating. Each inverter 31 has an independent limiting space, making it easier for technicians to identify and access specific inverter units, simplifying the maintenance and troubleshooting process. By adding limiters 23 in the inverter mounting rack 20 and forming limiting spaces, this design not only improves the installation accuracy and stability of the inverters 31, but also improves the heat dissipation performance, simplifies the maintenance process, and enhances the flexibility and reliability of the system. It can be understood that the limiters 23 can be L-shaped brackets, straight barriers, U-shaped metal or plastic slots, both ends of which can be fixed on the hanging pieces 22, and the middle part is used to accommodate and limit the inverters 31. It can also be a guide rail type limiter, which is used in cooperation with the sliding rail, and a limiting block or stop block is arranged at the end of the sliding rail to prevent the inverter from sliding out.

[0043] The first column 111, the second column 112, the third column 113 and the fourth column 114 are arranged at intervals and arranged along the first direction (i.e. the direction of the inverter arrangement). The four columns successively enclose a closed or semi-closed installation cavity 12 for accommodating inverters and other related components. The opening 13 is provided at least between two adjacent columns: this means that there can be one or more openings 13 between the first column 111 and the second column 112, between the second column 112 and the third column 113, between the third column 113 and the fourth column 114, or between the fourth column 114 and the first column 111. The installation cavity 12 enclosed by the four columns can effectively utilize the internal space, ensuring that all components are reasonably placed in a compact space, suitable for limited space environments. The four columns not only provide the necessary structural support for the frame, but also enhance the stability of the entire cabinet 10, especially when encountering external impact during transportation or installation, and can maintain the shape unchanged. The design of the opening 13 allows technicians to easily access the inverters and other components in the installation cavity 12, simplifying maintenance and repair work. The position of the opening can be flexibly adjusted according to actual needs to provide the best operational convenience. If the opening 13 is in the right place, it can serve as a ventilation port to help improve air flow in the installation cavity 12, thereby improving heat dissipation efficiency and reducing the risk of overheating.
