[0034] The following Figures 1 to 4 and through specific embodiments to further illustrate the technical solutions of the present utility model.

[0035] An inverter housing, comprising an upper cover 1 and a base 2;

[0036] The upper cover 1 includes a top plate 11 and two side plates 12. The two side plates 12 are disposed on both sides of the bottom of the top plate 11 relatively parallelly. The side plates 12 extend in a direction away from the top plate 11, and a male fastener assembly 30 is provided at the bottom of the side plates 12;

[0037] The base 2 includes a bottom plate 21 and two end plates 22. The two end plates 22 are disposed at both ends of the top of the bottom plate 21 relatively parallelly. The end plates 22 extend in a direction away from the bottom plate 21, and female fastener assemblies 40 that cooperate with the male fastener assembly 30 are provided on both sides of the bottom plate 21;

[0038] The male fastener assembly 30 of the upper cover 1 is assembled with the female fastener assembly 40 of the base 2 from top to bottom to form the inverter housing.

[0039] The upper cover 1 includes a top plate 11 and side plates 12 extending downward from both left and right sides of the top plate 11. The base 2 includes a bottom plate 21 and end plates 22 extending upward from both front and rear ends of the bottom plate 21. When the upper cover 1 and the base 2 are assembled together, the top plate 11, the two side plates 12, the two end plates 22, and the bottom plate 21 form an inverter housing with an accommodation cavity inside. By connecting or separating the male fastener components 30 located at the bottoms of the two side plates 12 and the female fastener components 40 located on both sides of the bottom plate, the assembly or disassembly of the upper cover 1 and the base 2 can be achieved. Compared with the traditional bolt connection method, the inverter housing of the present utility model greatly reduces the installation time and improves the working efficiency of the assembly; since the cumbersome screw tightening operation is reduced, the labor amount of the workers is reduced, thereby reducing the labor cost. On the other hand, since it can be quickly disassembled, the inverter housing becomes more convenient when internal components need to be repaired or replaced. Maintenance personnel can quickly open the housing, perform inspections, repairs, or replacement operations, and then quickly reassemble it, improving the repair efficiency.

[0040] Further, the male fastener components 30 are a plurality of deformable blocks 31, and the plurality of deformable blocks 31 are respectively arranged at the bottoms of the two side plates 12;

[0041] The female fastener components 40 are a plurality of mounting grooves 41, the mounting grooves 41 penetrate through the bottom plate 21 up and down, and the plurality of mounting grooves 41 are respectively arranged on both sides of the bottom plate 21;

[0042] During the process that the deformable blocks 31 pass through the mounting grooves 41 from top to bottom, the deformable blocks 31 are deformed by the extrusion of the mounting grooves 41; after the deformable blocks 31 pass through the mounting grooves 41, the deformable blocks 31 recover, and the deformable blocks 31 cannot be detached from the mounting grooves 41 from bottom to top;

[0043] The positions of the deformable blocks 31 and the mounting grooves 41 on each side correspond one by one.

[0044] The design that the deformable blocks 31 and the mounting grooves 41 match each other to achieve assembly makes the assembly process of the upper cover 1 and the base 2 simpler and more efficient. Workers only need to align the deformable blocks 31 at the bottoms of the two side plates 12 with the mounting grooves 41 on both sides of the bottom plate 21 respectively, and then press the upper cover 1 and / or the base 2 relatively with a little force to achieve the quick connection of the two, without using additional tools or performing complex operations.

[0045] Since the deformable card block 31 has the ability to deform, in the process of the deformable card block 31 passing through the card slot 41, the card slot 41 squeezes the deformable card block 31, so that the deformable card block 31 shrinks to the point where it can pass through the card slot 41 as a whole; when the deformable card block 31 completely passes through the card slot 41, the deformable card block 31 returns to the state before being squeezed and shrunk, and the restored deformable card block 31 cannot be separated from the card slot 41. It is necessary to squeeze the deformable card block 31 with external force to shrink it to the point where it can pass through the card slot 41, and then the deformable card block 31 can be separated from the card slot 41 from bottom to top, thereby realizing the disassembly and assembly of the upper cover 1 and the base 2. The design of the assembly of the deformable card block 31 and the card slot 41 makes the inverter housing more neat and beautiful in appearance, without exposed bolt heads or nuts, compared with the previous method of assembly and fastening with screws. This improves the overall texture of the product.

[0046] The deformation block 31 can be a structure with a deformation part or a block made of a material with deformation ability. For example, the deformation block 31 can be made of plastic with advantages such as low cost, lightness and environmental protection. What is important is that the plastic has good deformation ability.

[0047] Furthermore, the deformation block 31 includes an insertion block 311 and a tongue 312, and the insertion block 311 protrudes downward from the bottom of the side plate 12;

[0048] The latch tongue 312 includes a fixed end and a movable end, wherein the fixed end is connected to the insertion block 311, and the movable end extends upward and away from the insertion block 311, and the movable end can be deformed toward the insertion block 311;

[0049] When the upper cover 1 and the base 2 are assembled, the deformable block 31 is located at the bottom of the bottom plate 21 , and the movable end abuts against the bottom surface of the bottom plate 21 .

[0050] The fixed end of the latch tongue 312 is connected to the insertion block 311 , and the movable end thereof extends upward and away from the insertion block 311 , which is equivalent to the lower end of the latch tongue 312 being connected to the insertion block 311 and the upper end being the movable end. When the deformable card block 31 is inserted into the card slot 41 from top to bottom, the fixed end of the card tongue 312 first passes through the card slot 41; since the movable end extends in the direction away from the insertion block 311, during the continuous downward installation process, the movable end of the card tongue 312 will be squeezed by the card slot 41 toward the insertion block 311 when passing through the card slot 41. When the (active end of) the card tongue 312 completely passes through the card slot 41, the deformable card 31 passes through the card slot 41 as a whole and is located at the bottom of the bottom plate 21 as a whole; and the movable end of the card tongue 312 is no longer squeezed by force and will recover in the direction away from the insertion block 311, then the movable end will abut against the bottom surface of the bottom plate 21, and in the absence of external force squeezing the card tongue 312 to deform it, the deformable card 31 cannot be separated from the card slot 41. When it reaches the bottom, the movable end will abut against the bottom of the bottom plate 21, forming an outward supporting force, thereby enhancing the connection stability between the upper cover 1 and the base 2.

[0051] Furthermore, the length of the card slot 41 is the same as the length of the insertion block 311 , and the width of the card slot 41 is greater than the width of the insertion block 311 and less than the width of the deformation card block 31 .

[0052] The length of the card slot 41 is the same as that of the insertion block 311, which can ensure that the insertion block 311 can be smoothly and accurately inserted into the card slot 41. During the assembly process, this precise guiding property reduces assembly errors and improves assembly accuracy.

[0053] In addition, the width of the card slot 41 is greater than the width of the plug-in block 311, but less than the overall width of the deformed card block 31, which can ensure that the plug-in block 311 can easily enter the card slot 41. Since the deformed card block 31 also includes a latch 312, but the movable end of the latch 312 has the ability to deform, in the process of the deformed card block 31 passing through the card slot 41, the latch 312 deforms and shrinks toward the plug-in block 311, so that the deformed card block 31 can completely pass through the card slot 41. After the deformed card block 31 is assembled, the latch 312 is restored. At this time, the width of the deformed card block 31 is greater than the width of the card slot 41, and it cannot be separated from the card slot 41. This design ensures that the inverter housing has a stable snap-fit ​​effect after assembly and is not easy to loosen.

[0054] Furthermore, an arc portion 313 is provided at the top of the movable end, and the arc portion 313 is formed by bending the side of the tongue 312 away from the insertion block 311 from bottom to top to approach the side of the tongue 312 close to the insertion block 311 .

[0055] The arc portion 313 at the top of the tongue 312 helps the deformation block 31 and the mounting groove 41 to be disassembled. When the movable end of the tongue 312 is squeezed towards the insertion block 311 and the deformation block 31 is pushed upward, the arc portion 313 can pass through the bottom opening of the mounting groove 41 more smoothly, making the disassembly of the deformation block 31 and the mounting groove 41 smoother.

[0056] Furthermore, a top stop edge 221 is provided at the top of the end plate 22, and side stop edges 222 are provided on both sides of the end plate 22. The top stop edge 221 and the side stop edges 222 are perpendicular to the end plate 22 respectively. The top stop edges 221 at both ends extend towards each other respectively, and the side stop edges 222 at both ends on the same side extend towards each other respectively. When the upper cover 1 and the base 2 are assembled, the top stop edge 221 and the side stop edges 222 are surrounded by the upper cover 1.

[0057] The addition of the top stop edge 221 and the side stop edges 222 makes the structure of the end plate 22 more stable. These stop edges not only enhance the strength of the end plate 22 itself but also improve the connection strength between the end plate 22 and the upper cover 1, thereby enhancing the structural stability of the entire inverter housing. In addition, the top stop edge 221 and the side stop edges 222 play an accurate guiding role during the assembly process. These stop edges ensure the accurate alignment between the upper cover 1 and the base 2, avoiding misalignment or deviation during the assembly process and improving the assembly accuracy.

[0058] After the upper cover 1 and the base 2 are assembled, the top stop edge 221 and the side stop edges 222 form a surrounding structure at the connection edge of the inverter housing. These stop edges can effectively prevent external dust, moisture, or other foreign objects from entering the inverter, thereby protecting the internal electronic components from damage.

[0059] Furthermore, limit blocks 13 are respectively provided on the inner sides of both ends of the side plate 12. The limit blocks 13 are perpendicular to the side plate 12. When the upper cover 1 and the base 2 are assembled, the limit blocks 13 at both ends are respectively attached to the end plates 22 at both ends.

[0060] The design of the limit blocks 13 ensures the accurate alignment of the upper cover 1 and the base 2 during assembly. Since the limit blocks 13 are attached to the end plates 22, they will come into contact with each other and limit each other's positions during assembly, thus preventing misalignment or deviation during the assembly process. The attachment of the limit blocks 13 to the end plates 22 forms a stable connection point, which helps to prevent accidental loosening of the inverter housing during use. This design ensures the durability and reliability of the housing.

[0061] Furthermore, the plane where the top of the side baffle 222 is located is not higher than the plane where the bottom of the limit block 13 is located.

[0062] When the upper cover 1 and the base 2 are installed, the top of the side baffle 222 is not higher than the bottom of the limit block 13, ensuring that there is no interference between the two during the assembly process, enabling the upper cover 1 to smoothly descend and dock with the base 2, improving the fluency of the inverter housing assembly, reducing the assembly time, increasing the production efficiency, and reducing the risk of assembly difficulties or damage caused by the interference of the structural components of the upper cover 1 and the base 2.

[0063] Furthermore, both sides of the bottom plate 21 are provided with bending edges 23, the bending edges 23 include a connecting portion 231 and a supporting portion 232, the connecting portion 231 and the supporting portion 232 are perpendicular to each other, one end of the connecting portion 231 away from the supporting portion 232 is connected to the bottom plate 21, and the supporting portion 232 is parallel to the bottom plate 21.

[0064] The introduction of the bending edge 23 significantly enhances the structural stability of the inverter housing. The design in which the connecting portion 231 and the supporting portion 232 are perpendicular to each other provides additional support to both sides of the bottom plate 21, thereby improving the impact resistance and compressive resistance of the entire housing.

[0065] Due to the design that the supporting portion 232 is parallel to the bottom plate 21, it helps to increase the distance between the bottom plate 21 and the supporting plane, thereby optimizing the heat dissipation performance. This is particularly important for electronic devices such as inverters with relatively large heat generation, and can effectively prevent internal components from being damaged due to overheating.

[0066] Furthermore, the supporting portion 232 is provided with mounting holes 233.

[0067] The design of the bending edge 23 can provide more options for the installation and fixation of the inverter housing. By providing mounting holes 233 in the supporting portion 232, the inverter can be more firmly installed on brackets, cabinets or other devices through the mounting holes 233, thereby improving the stability and reliability of its overall structure.

[0068] Further explanation, the mounting holes 233 on the supporting portion 232 allow users to select appropriate fixing methods according to actual needs. For example, users can use screws, bolts or other fasteners to fix the inverter housing at the required position through the mounting holes, and this design increases the flexibility and adaptability of the installation.

[0069] It is worth noting that several kinds of assembly holes are provided on the sheet metal surface of the inverter housing, and these assembly holes are respectively used to match and install necessary components for realizing the functions of the inverter such as display screens, operation screens, operation buttons, power terminal ports, A / C conversion ports, etc.

[0070] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
