Description

Technical Field

[0001] The utility model relates to the technical field of inverter equipment, in particular to a cabinet component and an inverter. Background Art

[0002] At present, photovoltaic power generation is a technology that uses solar energy to convert into electrical energy. Its core equipment is the photovoltaic inverter, which is used to convert direct current into alternating current and feed it into the power grid. The working environment of photovoltaic inverters is often harsh, such as outdoor exposure, high temperature and high humidity. Therefore, photovoltaic inverters are usually installed in cabinets to protect the electronic components inside.

[0003] The photovoltaic inverter cabinet in the related art generally adopts the fixing method of front bolts or back bolts. Specifically, the fixing method of front bolts is to fix the cover plate and the shell of the cabinet together from the front by bolts. However, the bolts are exposed to the outside, which affects the appearance of the inverter. The fixing method of back bolts is to fix the bolts from the back. However, for on-site installation and maintenance, the operating space is limited and the time cost is high. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a cabinet assembly.

[0006] A second aspect of the embodiments of the present invention provides an inverter.

[0007] In view of this, according to the first aspect of an embodiment of the utility model, a cabinet assembly is provided, the cabinet assembly comprising: a cabinet body, the cabinet body comprising a bottom plate and a surrounding plate, the surrounding plate is connected to the bottom plate and encloses to form a groove; a cover body, arranged on the side of the surrounding plate away from the bottom plate; an installation assembly, arranged on the surrounding plate and capable of moving relative to the surrounding plate, when the installation assembly moves to the target position, the installation assembly is connected to the cover body, the cover body and the groove wall of the groove enclose to form an installation cavity, and the installation cavity is used to accommodate electrical components.

[0008] The cabinet assembly provided by the embodiment of the utility model includes a cabinet body, a cover body and an installation assembly. Specifically, the cabinet body includes a bottom plate and a surrounding plate connected to each other, and the bottom plate and the surrounding plate are combined to form a groove. Optionally, the surrounding plate includes a plurality of side plates connected in sequence, and each side plate is connected to the bottom plate to form a groove.

[0009] The cover body is arranged on a side of the enclosure plate away from the bottom plate, that is, the cover body is arranged on the notch of the groove, and the cover body is opposite to the bottom plate.

[0010] The mounting assembly is arranged on the enclosure, and the mounting assembly can move relative to the enclosure. When the mounting assembly moves to a target position, the mounting assembly is connected to the cover body, thereby achieving a fixed connection between the enclosure and the cover body.

[0011] It can be understood that since the bottom plate is opposite to the cover body, that is, the installation and fixation between the cabinet body and the cover body is achieved from the side of the cabinet assembly, compared with the fixing method using front bolts in the related art, it effectively avoids the bolts used for fixing from being exposed from the front, improves the aesthetics of the inverter with the cabinet assembly, and meets the trend of inverter home appliances.

[0012] In addition, compared with the fixing method using back bolts in the related art, the side of the cabinet assembly has a larger operating space, which reduces the difficulty of operation, facilitates on-site installation and maintenance of the inverter, improves the efficiency of installation and maintenance, and saves time costs.

[0013] When the mounting assembly is connected to the cover body, the cover body and the groove wall of the groove form an installation cavity, and the installation cavity is used to accommodate electrical components. That is to say, the electrical components are encapsulated in the cabinet assembly to protect the electrical components, thereby ensuring the normal operation of the electrical components even in harsh working environments.

[0014] Optionally, the installation component is detachably connected to the cover body, that is, when the installation component moves to the target position, the installation component is connected to the cover body, and when the installation component moves in the opposite direction from the target position, it can be separated from the cover body, thereby realizing disassembly between the cover body and the cabinet body, which is easy to operate and facilitates the installation and maintenance of the inverter.

[0015] Optionally, the base plate and the enclosure plate are an integral structure.

[0016] Optionally, the electrical device is a body of an inverter.

[0017] In addition, the cabinet assembly provided by the above technical solution of the utility model also has the following additional technical features:

[0018] In some technical solutions, optionally, the cover body includes a cover plate and a mounting member, wherein the mounting member is provided on the cover plate, and when the mounting assembly is located at the target position, the mounting member is connected to the mounting assembly; wherein, along the thickness direction of the cover plate, at least a portion of the mounting member is opposite to the cover plate.

[0019] In this technical solution, it is defined that the cover body includes a cover plate and a mounting member. Specifically, the mounting member is arranged on the cover plate. When the mounting assembly moves to the target position, the mounting assembly is connected to the mounting member, thereby connecting the mounting assembly to the cover body, thereby realizing the installation and fixation between the cabinet body and the cover body.

[0020] Along the thickness direction of the cover plate, at least part of the mounting member is opposite to the cover plate, that is, the mounting member is located on the side of the cover plate facing the cabinet body. When the mounting assembly moves to the target position, the mounting assembly is connected with the mounting member, so that in the front direction of the cabinet assembly, the mounting assembly can be reduced from being exposed from the side of the cabinet assembly, further improving the aesthetics of the inverter having the cabinet assembly.

[0021] Optionally, a portion of the cover plate is bent multiple times to form a mounting piece, that is, the cover plate and the mounting piece are an integrated structure, which is beneficial to improve the connection strength between the cover plate and the mounting piece and ensure effective fixation between the cabinet body and the cover body.

[0022] In addition, the integrated structure is also conducive to the mass production of the cover, thereby reducing the difficulty of manufacturing the cover, and further helping to reduce the production cost of the cabinet assembly and the inverter having the cabinet assembly.

[0023] In some technical schemes, optionally, a first limit surface is provided on the side of the mounting member facing away from the cabinet body; the mounting component is provided with a second limit surface, and when the mounting component moves to the target position, along the thickness direction of the cover plate, the second limit surface is located on the side of the mounting member facing away from the cabinet body and is offset against the first limit surface.

[0024] In this technical solution, it is defined that a first limiting surface is provided on a side of the mounting member facing away from the cabinet body, that is, the first limiting surface is located on a side of the mounting member facing the cover plate.

[0025] The mounting assembly is provided with a second limit surface. When the mounting assembly moves to the target position, along the thickness direction of the cover plate, the second limit surface is located on the side of the mounting piece away from the cabinet body, and the second limit surface is offset against the first limit surface, thereby forming a limit between the mounting assembly and the mounting piece in the thickness direction of the cover plate, thereby achieving reliable fixation between the cabinet body and the cover body.

[0026] In addition, since the second limit surface is offset against the first limit surface, that is, the second limit surface is tightly fitted with the first limit surface, when the inverter with the cabinet assembly is located in a harsh working environment, such as in windy conditions, it can avoid the cover body from shaking relative to the cabinet body and producing abnormal noise, thereby improving the sealing of the installation cavity and reducing the collision and wear between the cover body and the cabinet body, thereby extending the service life of the cabinet assembly and ensuring the normal operation of the inverter.

[0027] In some technical solutions, optionally, the cover body also includes a guide portion, a first end of which is connected to the mounting member, and a second end of the guide portion extends obliquely toward the side where the cabinet is located; wherein a guide surface is provided on the side of the guide portion facing away from the cabinet, and the guide surface is connected to the first limiting surface.

[0028] In this technical solution, it is defined that the cover body further includes a guide portion, specifically, one end of the guide portion is connected to the mounting member, and the other end of the guide portion extends obliquely toward the side where the cabinet is located. In other words, the guide surface is an inclined surface.

[0029] When the installation component moves to the target position relative to the enclosure, that is, the second limit surface of the installation component moves from the side of the installation part toward the cabinet to the side of the installation part away from the cabinet, and when the installation component moves to the target position, the second limit surface is offset against the first limit surface. By setting the guide surface, the movement of the installation component can be guided, so that the second limit surface can quickly fit tightly with the first limit surface under the action of the guide surface, thereby achieving reliable fixation between the cabinet and the cover, and improving the installation and maintenance efficiency of the inverter.

[0030] Optionally, at least one end of the mounting member is bent toward the side where the cabinet is located to form a guide portion. In other words, the mounting member and the guide portion are an integrated structure.

[0031] In some technical solutions, optionally, the mounting piece is provided with a positioning portion, and the cabinet assembly further includes a positioning component, the positioning component is provided on the enclosure, and the positioning component can cooperate with the positioning portion.

[0032] In this technical solution, it is defined that the cabinet assembly also includes a positioning assembly. Specifically, the positioning assembly is arranged on the enclosure, and a positioning portion is arranged on the mounting member. The positioning portion can cooperate with the positioning assembly, so as to play a role of pre-positioning during the installation process of the cover body and the cabinet body, thereby improving the installation efficiency of the cover body and the cabinet body, and facilitating the alignment between the installation assembly and the mounting member, so that when the installation assembly moves to the target position, the installation assembly can achieve effective matching connection with the mounting member, ensuring reliable fixation between the cabinet body and the cover body.

[0033] Optionally, there are multiple positioning assemblies, at least two of which are located on opposite sides of the enclosure, and the positioning portions correspond one to one with the positioning assemblies.

[0034] In some technical solutions, optionally, the positioning portion includes a positioning hole, and the positioning assembly includes a positioning bracket and a positioning member, wherein the positioning bracket is arranged on the enclosure, the positioning member is arranged on the positioning bracket, and the positioning member can be inserted into the positioning hole.

[0035] In this technical solution, it is defined that the positioning component includes a positioning bracket and a positioning member. Specifically, the positioning bracket is arranged on the enclosure, the positioning member is arranged on the positioning bracket, and the positioning member can be inserted into the positioning hole, so that during the installation process of the cover body and the cabinet body, it plays a role of pre-positioning, improves the installation efficiency of the cover body and the cabinet body, and facilitates the alignment between the installation component and the installation member, so that when the installation component moves to the target position, the installation component can achieve effective matching connection with the installation member, ensuring reliable fixation between the cabinet body and the cover body.

[0036] Moreover, it can be understood that inserting the positioning piece into the positioning hole for pre-positioning can limit the cover body in multiple directions, thereby preventing the cover body from moving relative to the cabinet body, which in turn causes the installation component to be unable to effectively cooperate with the installation piece when it moves to the target position, further improving the installation efficiency of the cabinet components, reducing the difficulty of operation, and saving time costs.

[0037] Optionally, the positioning member includes a positioning pin.

[0038] In some technical solutions, optionally, the positioning bracket includes a positioning surface, and the positioning surface can be fitted with a side surface of the mounting member facing the cabinet.

[0040] It is understandable that a seal is provided at the connection between the cover body and the enclosure. When the cover body presses the seal, the seal has a certain amount of compression to improve the sealing effect of the installation cavity. However, too much or too little compression will affect the sealing and reliability of the installation cavity.

[0041] By setting the positioning surface, when the cover is installed, when the positioning surface is in contact with the side of the mounting piece facing the cabinet, it means that the compression of the seal just meets the requirement. That is to say, the installation position of the positioning bracket can be reasonably arranged according to the required compression of the seal to ensure that when the positioning surface is in contact with the side of the mounting piece facing the cabinet, the compression of the seal meets the design requirements, which is beneficial to further improve the sealing effect of the installation cavity, enhance the waterproof and dustproof performance of the cabinet components, and meet the IP (Ingress Protection) protection level requirements.

[0044] In this technical solution, it is specified that the mounting piece is also provided with an opening. Specifically, the opening is connected to the positioning hole, and the width of the opening is greater than or equal to the diameter of the positioning hole. Therefore, when the cover body and the cabinet body are pre-positioned, the positioning piece can be quickly inserted into the positioning hole to achieve limiting of the cover body in multiple directions, which is beneficial to further improve the installation and maintenance efficiency of the cabinet components.

[0101] The cabinet assembly 100 provided by the embodiment of the utility model includes a cabinet body 110, a cover body 120 and an installation assembly 130. Specifically, the cabinet body 110 includes a bottom plate 111 and a surrounding plate 112 connected to each other, and the bottom plate 111 and the surrounding plate 112 are enclosed to form a groove 113.

That is to say, the electrical components are encapsulated in the cabinet assembly 100 to protect the electrical components, thereby ensuring the normal operation of the electrical components even in harsh working environments.

[0107] Optionally, the installation component 130 is detachably connected to the cover body 120, that is, when the installation component 130 moves to the target position, the installation component 130 is connected to the cover body 120, and when the installation component 130 moves in the opposite direction from the target position, it can be separated from the cover body 120, thereby realizing the disassembly between the cover body 120 and the cabinet body 110, which is easy to operate and convenient for the installation and maintenance of the inverter.

[0108] Optionally, the bottom plate 111 and the enclosure plate 112 are an integral structure.

[0109] Optionally, the electrical device is a body of an inverter.

[0110] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, in some embodiments, optionally, the cover body 120 includes a cover plate 121 and a mounting member 122, wherein the mounting member 122 is disposed on the cover plate 121, and when the mounting assembly 130 is located at the target position, the mounting member 122 is connected to the mounting assembly 130; wherein, along the thickness direction of the cover plate 121, at least a portion of the mounting member 122 is opposite to the cover plate 121.

[0111] In this embodiment, it is defined that the cover body 120 includes a cover plate 121 and a mounting member 122. Specifically, the mounting member 122 is arranged on the cover plate 121. When the mounting component 130 moves to the target position, the mounting component 130 is connected to the mounting member 122, so that the mounting component 130 is connected to the cover body 120, thereby realizing the installation and fixation between the cabinet body 110 and the cover body 120.

[0112] Along the thickness direction of the cover plate 121, at least part of the mounting member 122 is opposite to the cover plate 121, that is, the mounting member 122 is located on the side of the cover plate 121 facing the cabinet body 110. When the mounting assembly 130 moves to the target position, the mounting assembly 130 is connected with the mounting member 122, so that in the front direction of the cabinet assembly 100, the mounting assembly 130 can be reduced from being exposed from the side of the cabinet assembly 100, further improving the aesthetics of the inverter having the cabinet assembly 100.

[0113] Optionally, a portion of the cover plate 121 is bent multiple times to form the mounting member 122, that is, the cover plate 121 and the mounting member 122 are an integral structure, which is beneficial to improve the connection strength between the cover plate 121 and the mounting member 122 and ensure effective fixation between the cabinet body 110 and the cover body 120.

[0114] In addition, the integrated structure is also conducive to the mass production of the cover body 120, thereby reducing the difficulty of manufacturing the cover body 120, and further helping to reduce the production cost of the cabinet assembly 100 and the inverter having the cabinet assembly 100.

[0115] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.15 As shown, in some embodiments, optionally, a first limit surface 123 is provided on the side of the mounting member 122 facing away from the cabinet 110; the mounting component 130 is provided with a second limit surface 131, and when the mounting component 130 moves to the target position, along the thickness direction of the cover plate 121, the second limit surface 131 is located on the side of the mounting member 122 facing away from the cabinet 110, and is against the first limit surface 123.

[0116] In this embodiment, a first limiting surface 123 is defined on a side of the mounting member 122 facing away from the cabinet 110 , that is, the first limiting surface 123 is located on a side of the mounting member 122 facing the cover plate 121 .

[0117] The mounting component 130 is provided with a second limiting surface 131. When the mounting component 130 moves to the target position, along the thickness direction of the cover plate 121, the second limiting surface 131 is located on the side of the mounting member 122 away from the cabinet 110, and the second limiting surface 131 is abutted against the first limiting surface 123, so that a limit is formed between the mounting component 130 and the mounting member 122 in the thickness direction of the cover plate 121, thereby realizing reliable fixation between the cabinet 110 and the cover body 120.

[0118] In addition, since the second limit surface 131 is offset against the first limit surface 123, that is, the second limit surface 131 is tightly fitted with the first limit surface 123, when the inverter having the cabinet assembly 100 is located in a harsh working environment, such as under windy conditions, it can avoid the cover body 120 from shaking relative to the cabinet body 110 and generating abnormal noises, thereby improving the sealing of the installation cavity 140 and reducing the collision and wear between the cover body 120 and the cabinet body 110, thereby extending the service life of the cabinet assembly 100 and ensuring the normal operation of the inverter.

[0119] like Figure 1 , Figure 3 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, in some embodiments, optionally, the cover body 120 also includes a guide portion 124, a first end of the guide portion 124 is connected to the mounting member 122, and a second end of the guide portion 124 extends obliquely toward the side where the cabinet 110 is located; wherein a guide surface 125 is provided on the side of the guide portion 124 facing away from the cabinet 110, and the guide surface 125 is connected to the first limiting surface 123.

[0120] In this embodiment, the cover 120 is defined to further include a guide portion 124. Specifically, one end of the guide portion 124 is connected to the mounting member 122, and the other end thereof extends obliquely toward the side where the cabinet 110 is located. In other words, the guide surface 125 is an inclined surface.

[0121] When the installation component 130 moves to the target position relative to the enclosure 112, that is, the second limit surface 131 of the installation component 130 moves from the side of the installation component 122 toward the cabinet 110 to the side of the installation component 122 away from the cabinet 110, and when the installation component 130 moves to the target position, the second limit surface 131 is against the first limit surface 123. By setting the guide surface 125, the movement of the installation component 130 can be guided, so that the second limit surface 131 is quickly and tightly fitted with the first limit surface 123 under the action of the guide surface 125, thereby realizing reliable fixation between the cabinet 110 and the cover body 120, thereby improving the installation and maintenance efficiency of the inverter.

[0122] Optionally, at least one end of the mounting member 122 is bent toward the side where the cabinet 110 is located to form a guide portion 124. In other words, the mounting member 122 and the guide portion 124 are an integrated structure.

[0123] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.12 , Fig.14 and Fig.15 As shown, in some embodiments, optionally, the mounting member 122 is provided with a positioning portion 126 , and the cabinet assembly 100 further includes a positioning assembly 150 , which is provided on the enclosure 112 , and the positioning assembly 150 can cooperate with the positioning portion 126 .

[0124] In this embodiment, it is defined that the cabinet assembly 100 also includes a positioning assembly 150. Specifically, the positioning assembly 150 is arranged on the enclosure 112, and a positioning portion 126 is arranged on the mounting member 122. The positioning portion 126 can cooperate with the positioning assembly 150, so as to play a role of pre-positioning during the installation process of the cover body 120 and the cabinet body 110, thereby improving the installation efficiency of the cover body 120 and the cabinet body 110, and facilitating the alignment between the mounting assembly 130 and the mounting member 122, so that when the mounting assembly 130 moves to the target position, the mounting assembly 130 can achieve an effective matching connection with the mounting member 122, thereby ensuring reliable fixation between the cabinet body 110 and the cover body 120.

[0125] Optionally, there are multiple positioning assemblies 150 , and at least two positioning assemblies 150 are located on two opposite sides of the enclosure 112 , and the positioning portions 126 correspond one-to-one to the positioning assemblies 150 .

[0126] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.12 , Fig.14 and Fig.15 As shown, in some embodiments, optionally, the positioning portion 126 includes a positioning hole 127, and the positioning assembly 150 includes a positioning bracket 151 and a positioning member 152, wherein the positioning bracket 151 is disposed on the enclosure 112, the positioning member 152 is disposed on the positioning bracket 151, and the positioning member 152 can be inserted into the positioning hole 127.

[0127] In this embodiment, the positioning component 150 is defined to include a positioning bracket 151 and a positioning member 152. Specifically, the positioning bracket 151 is arranged on the enclosure 112, the positioning member 152 is arranged on the positioning bracket 151, and the positioning member 152 can be inserted into the positioning hole 127, so that during the installation process of the cover body 120 and the cabinet body 110, it plays a role of pre-positioning, improves the installation efficiency of the cover body 120 and the cabinet body 110, and facilitates the alignment between the installation component 130 and the installation member 122, so that when the installation component 130 moves to the target position, the installation component 130 can achieve an effective matching connection with the installation member 122, ensuring reliable fixation between the cabinet body 110 and the cover body 120.

[0128] Moreover, it can be understood that inserting the positioning member 152 into the positioning hole 127 for pre-positioning can limit the cover body 120 in multiple directions, thereby preventing the cover body 120 from moving relative to the cabinet body 110, which in turn causes the installation component 130 to be unable to effectively cooperate with the installation member 122 when moving to the target position, further improving the installation efficiency of the cabinet component 100, reducing the difficulty of operation, and saving time costs.

[0129] Optionally, the positioning member 152 includes a positioning pin.

[0130] like Figure 8 As shown, in some embodiments, optionally, the positioning bracket 151 includes a positioning surface 153 , and the positioning surface 153 can be aligned with a side surface of the mounting member 122 facing the cabinet 110 .

[0131] In this embodiment, it is defined that the positioning bracket 151 includes a positioning surface 153 . Specifically, the positioning surface 153 can be in contact with a side surface of the mounting member 122 facing the cabinet 110 .

[0132] It is understandable that a seal 210 is provided at the connection between the cover body 120 and the enclosure 112. When the cover body 120 presses the seal 210, the seal 210 has a certain amount of compression to enhance the sealing effect of the installation cavity 140. However, too much or too little compression affects the sealing and reliability of the installation cavity 140.

[0133] By setting the positioning surface 153, when the cover body 120 is installed, when the positioning surface 153 fits with the side of the mounting member 122 facing the cabinet 110, it means that the compression amount of the seal 210 just meets the requirement. In other words, the installation position of the positioning bracket 151 can be reasonably arranged according to the required compression amount of the seal 210 to ensure that when the positioning surface 153 fits with the side of the mounting member 122 facing the cabinet 110, the compression amount of the seal 210 meets the design requirements, which is beneficial to further improve the sealing effect of the installation cavity 140, enhance the waterproof and dustproof performance of the cabinet assembly 100, and meet the requirements of the IP protection level.

[0134] Optionally, a portion of the positioning bracket 151 is bent so that the positioning bracket 151 is formed into a first portion and a second portion, the first portion is connected to the enclosure 112 , and the second portion is provided with a positioning surface 153 .

[0135] like Figure 2 and Fig.14 As shown, in some embodiments, optionally, the mounting member 122 is further provided with an opening 128 , and the opening 128 is communicated with the positioning hole 127 ; wherein the width of the opening 128 is greater than or equal to the diameter of the positioning hole 127 .

[0136] In this embodiment, it is defined that the mounting member 122 is also provided with an opening 128. Specifically, the opening 128 is connected to the positioning hole 127, and the width of the opening 128 is greater than or equal to the diameter of the positioning hole 127. Therefore, when the cover body 120 and the cabinet body 110 are pre-positioned, the positioning member 152 can be quickly inserted into the positioning hole 127 to achieve limiting of the cover body 120 in multiple directions, which is beneficial to further improve the installation and maintenance efficiency of the cabinet assembly 100.

[0137] Optionally, the number of the mounting members 122 is at least two, and when the at least two mounting members 122 are respectively located on two opposite sides of the cover plate 121 , the openings 128 on the at least two mounting members 122 are opposite to each other.

[0138] Specifically, Figure 2As shown, at least two mounting members 122 include a first mounting member and a second mounting member, and the first mounting member and the second mounting member are respectively located on opposite sides of the cover plate 121, wherein the opening 128 on the first mounting member is located on the side of the positioning hole 127 on the first mounting member close to the second mounting member, and the opening 128 on the second mounting member is located on the side of the positioning hole 127 on the second mounting member close to the first mounting member, that is, the positioning hole 127 on the left first mounting member opens to the right, and the positioning hole 127 on the right second mounting member opens to the left, which is beneficial to further enhance the limiting effect of the cover body 120 and realize precise alignment between the mounting component 130 and the mounting member 122. When the mounting component 130 moves to the target position, it can realize effective matching connection with the mounting member 122, further improve the installation efficiency of the cabinet component 100, and save time cost.

[0139] like Figure 2 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.16 As shown, in some embodiments, optionally, the mounting member 122 is further provided with a first limiting portion 129, and the cabinet assembly 100 further includes a second limiting portion 160, and the second limiting portion 160 is provided on the mounting assembly 130, and when the mounting assembly 130 is located at the target position, the second limiting portion 160 cooperates with the first limiting portion 129.

[0140] In this embodiment, it is defined that the cabinet assembly 100 also includes a second limit portion 160. Specifically, the second limit portion 160 is arranged on the mounting assembly 130. When the mounting assembly 130 moves to the target position, the second limit portion 160 cooperates with the first limit portion 129 arranged on the mounting member 122, thereby improving the connection strength between the mounting member 122 and the mounting assembly 130, thereby achieving a reliable connection between the cover body 120 and the cabinet body 110, and improving the installation stability of the cabinet assembly 100.

[0141] like Figure 2 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.16 As shown, in some embodiments, optionally, the first limiting portion 129 includes a limiting hole 170 ; the second limiting portion 160 includes a limiting column 161 , and when the mounting assembly 130 is located at the target position, the limiting column 161 is inserted into the limiting hole 170 .

[0142] In this embodiment, the first limiting portion 129 is defined as a limiting hole 170, and the second limiting portion 160 is defined as a limiting column 161. When the mounting assembly 130 moves to the target position, the limiting column 161 is inserted into the limiting block to increase the connection strength between the mounting member 122 and the mounting assembly 130, thereby achieving a reliable connection between the cover body 120 and the cabinet body 110, and improving the installation stability of the cabinet assembly 100.

[0145] The fastener 134 is arranged on the mounting bracket 132, that is, during the process of the mounting bracket 132 rotating relative to the enclosure 112, the fastener 134 can be driven to rotate. When the mounting bracket 132 rotates to the target position, it is connected to the enclosure 112 through the fastener 134, so as to further increase the connection strength between the cover body 120 and the enclosure 112 on the basis of the coordinated connection between the mounting assembly 130 and the mounting member 122, thereby improving the installation reliability between the cover body 120 and the cabinet body 110, and can also improve the sealing of the mounting cavity 140, and improve the dustproof and waterproof performance of the cabinet assembly 100.

[0146] In addition, the fasteners 134 are disposed on the mounting bracket 132 , so there is no risk of separate storage and loss, which is beneficial for further improving the installation and maintenance efficiency of the cabinet assembly 100 .

[0147] Optionally, a portion of the mounting bracket 132 is bent to form a first bent portion and a second bent portion, the first bent portion is rotatably connected to the enclosure 112 via a connecting shaft 133, and the second bent portion is provided with a second limiting surface 131. The second limiting portion 160 is provided on the second bent portion.

[0148] Optionally, the fastener 134 includes a screw. The screw includes a spring screw. Specifically, the spring screw includes a fastening screw and a spring. Before the mounting assembly 130 rotates to the target position, due to the action of the spring, the tip of the fastening screw can be away from the enclosure 112 to avoid scratching the enclosure 112 during the rotation of the mounting assembly 130.

[0149] like Figure 3 , Figure 7 , Fig.17 and Fig.18 As shown, in some embodiments, optionally, the cabinet assembly 100 further includes a first sealing portion 180 , which is disposed in the groove 113 .

One end of the connecting shaft 133 is inserted into the first sealing cavity 181 through the axial hole from the outside of the groove 113, thereby improving the sealing of the installation cavity 140 and meeting the IP protection level requirements of the inverter having the cabinet assembly 100.

[0151] Optionally, the first sealing portion 180 and the enclosure 112 are an integral structure.

[0152] like Figure 3 , Figure 7 , Fig.17 and Fig.18 As shown, in some embodiments, optionally, the cabinet assembly 100 further includes a second sealing portion 190 , which is disposed in the groove 113 , and the second sealing portion 190 is provided with a second sealing cavity, and one end of the fastener 134 is inserted into the second sealing cavity.

It can be understood that a through hole is provided on the enclosure 112, and the through hole is connected to the second sealed cavity. One end of the fastener 134 is inserted into the second sealed cavity through the through hole from the outside of the groove 113, thereby improving the sealing of the installation cavity 140 and meeting the IP protection level requirements of the inverter having the cabinet assembly 100.

[0154] Optionally, the second sealing portion 190 and the enclosure 112 are an integral structure.

[0155] like Figure 2 , Figure 3 and Fig.18 As shown, in some embodiments, optionally, the cabinet assembly 100 further includes a seal 210 , which is disposed at the connection between the enclosure 112 and the cover 120 .

[0156] In this embodiment, it is defined that the cabinet assembly 100 also includes a seal 210. Specifically, the seal 210 is arranged at the connection between the enclosure 112 and the cover body 120, thereby sealing the connection between the enclosure 112 and the cover body 120, so that the installation cavity 140 is formed into a sealed cavity, which effectively prevents moisture, dust, etc. in the external environment from entering the installation cavity 140, avoids malfunctions of electrical components in the installation cavity 140, and ensures that the electrical components can work normally even in harsh environments such as outdoor open air, high temperature and high humidity, thereby extending the service life of the inverter.

[0157] Optionally, the seal 210 is a sealing ring, which can improve the sealing effect of the connection between the cover body 120 and the enclosure 112, improve the sealing of the installation cavity 140, and enhance the waterproof and dustproof performance of the cabinet assembly 100.

[0160] The cover 120 and the sealing member 210 are against each other on the side facing away from the enclosure 112, that is, after the cover 120 and the enclosure 112 are connected, the sealing member 210 has a certain amount of compression due to the pressing effect of the cover 120, so that the sealing effect of the connection between the cover 120 and the enclosure 112 can be further improved, and the sealing of the installation cavity 140 can be enhanced to meet the IP protection level requirements of the inverter having the cabinet assembly 100. Specifically, the inverter can meet the protection level of IP65 or above, and the working stability and reliability of the inverter in harsh environments can be improved.

[0161] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, there are multiple mounting assemblies 130 , and at least two mounting assemblies 130 are respectively disposed on both sides of the enclosure 112 .

Optionally, at least two mounting assemblies 130 are respectively disposed on two adjacent sides of the enclosure 112. And / or, at least two mounting assemblies 130 are respectively disposed on two opposite sides of the enclosure 112.

[0163] By setting up multiple installation components 130, and at least two installation components 130 are respectively located on both sides of the enclosure 112, when the multiple installation components 130 are moved to the target positions respectively, the multiple installation components 130 can be connected to the cover body 120, thereby improving the connection strength between the enclosure 112 and the cover body 120, improving the installation stability and reliability between the cover body 120 and the cabinet body 110, and facilitating further improving the sealing of the installation cavity 140, and enhancing the dustproof and waterproof performance of the cabinet assembly 100.

[0164] Optionally, when at least two mounting assemblies 130 are respectively located on opposite sides of the enclosure 112, the at least two mounting assemblies 130 are symmetrically arranged about the enclosure 112. Thus, after the at least two mounting assemblies 130 are respectively connected to the cover 120, the forces at various locations of the cover 120 and the cabinet 110 can be balanced, thereby achieving reliable installation between the cover 120 and the cabinet 110, preventing the cabinet assembly 100 from being deformed after long-term use, and extending the service life of the cabinet assembly 100.

[0165] In a specific embodiment, the photovoltaic inverter cabinet (cabinet assembly 100) includes:

[0166] The box body (cabinet 110) has a mounting cavity (recess 113) for inverter hardware and structural electrical components.

[0167] The cover plate (cover body 120) and the sealing strip (seal 210) are wrapped around the box body and clamped on the vertical edge of the box body end surface. The cover plate forms a sealed cavity (installation cavity 140) by compressing the sealing strip and the box body. The sealing strip has a certain amount of compression, which ensures that the cabinet meets the protection level of IP65 or above.

[0168] The bracket assembly (mounting assembly 130) is composed of a mounting bracket 132, a spring screw (fastener 134) and a protrusion (second limiting portion 160). The bracket assembly is screwed to the pressure-riveted sealing nut column (first sealing portion 180) inside the box body through a fixed plug-in (connecting shaft 133). The bracket assembly can rotate around the fixed plug-in. The bracket assembly is installed symmetrically on the left and right, with a total of 4 pieces.

[0169] The positioning bracket (positioning assembly 150) is fixed on the left and right sides of the box, and there are two pieces in total. It consists of a bracket (positioning bracket 151) and a positioning pin (positioning member 152). The positioning pin is fixed to the bracket by crimping.

[0170] The inner side of the box body includes a sealing nut column (first sealing portion 180). The bracket assembly is fixed to the outer two side surfaces of the box body through the fixing plug-in and the sealing nut column.

[0171] The left and right sides of the cover plate include inner flanges (mounting members 122 ), and the flanges include positioning holes 127 and upper and lower guide bends (guide portions 124 ).

[0172] The spring screw (fastener 134) is fixed to the mounting bracket 132 by riveting, and the protrusion is formed by extrusion of a mold. The protrusion is a small cylindrical boss (limiting column 161). The bracket assembly is fixed to the two outer sides of the box body by a fixed plug-in and a sealing nut column. The bracket assembly can rotate around the fixed plug-in.

[0173] like Figure 8 and Fig. 9 As shown, the bracket assembly is in the state of not buckling the cover plate. When the cover plate compresses the sealing strip, the bracket assembly is rotated, wherein, Fig. 9 , Fig.11 and Fig.13 The direction of the arrow is the direction of rotation.

[0174] like Fig.10 and Fig.11 As shown, the bracket assembly is in the installation process state, and the bracket assembly contacts the inner flange of the cover plate (installation member 122) through the cover plate guide bend (guide portion 124) until the bracket assembly and the inner flange of the cover plate are flush with each other (the first limiting surface 123 and the second limiting surface 131 are against each other). Fig.12 and Fig.13 The protrusion (limiting column 161) of the bracket assembly is exactly concentric with the positioning hole (limiting hole 170) of the cover. At this time, the prefabricated spring screw (fastener 134) on the bracket assembly is tightened by a tool to complete the installation of the bracket assembly. When the left and right brackets are installed, the installation of the cover and box of the inverter cabinet is completed.

[0175] When the cover plate is installed with the box body, the positioning pin on the positioning bracket and the positioning hole 127 of the cover plate play a role of positioning guide. When the cover plate contacts the positioning bracket (fits with the positioning surface 153), the bracket assembly is rotated at this time, and the positioning bracket also has a limiting function.

[0176] The IP protection level of the inverter cabinet is achieved by compressing the sealing strip with the cover, and the bracket assembly is connected and fixed to the outside of the box with the prefabricated waterproof sealing nut column inside the box.

[0177] The overall process is as follows: the sealing strip is wrapped around the box body and clamped on the vertical edge of the box body end face, and the bracket assembly is connected to the prefabricated waterproof sealing nut column on the inner side of the box body and fixed to the outer side of the box body. When the cover plate is fixed to the box body, under the guidance of the positioning pin (positioning member 152) on the positioning bracket (positioning assembly 150) and the positioning hole 127 of the cover plate (cover body 120), the cover plate is buckled on the box body and squeezes the sealing strip (seal 210). When the cover plate contacts the positioning bracket, the bracket assembly is rotated at this time, and the bracket assembly contacts the inner flange of the cover plate through the guide bending of the cover plate, until the bracket assembly and the inner flange of the cover plate are flush, and the protrusion of the bracket assembly is exactly concentrically positioned with the positioning hole of the cover plate. At this time, the prefabricated spring screws (fasteners 134) on the bracket assembly are tightened by tools to complete the installation of the bracket assembly (installation assembly 130). When the left and right side brackets (installation components 130) are installed, the installation of the cover plate (cover body 120) and the box body (cabinet body 110) of the inverter cabinet (cabinet component 100) is completed.

[0178] From the front, the bracket assembly and the positioning bracket are hidden in the back of the cover plate, and the fixing bolts and the mounting bracket are not visible. When the cover plate needs to be removed for maintenance, it is only necessary to loosen the spring screw (fastener 134) and then rotate the mounting bracket 132. The operation is simple and convenient, and there is no risk of needing to store separately and losing the bolts (fastener 134).
