[0051] Refer to the following Figures 1 to 16 The following describes a housing assembly 1 and an inverter 2 according to some embodiments of the present invention.

[0052] like Figure 1 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 16 As shown, the shell assembly 1 provided by the present invention is applied to the inverter 2, and the shell assembly 1 includes a box body 11, and the box body 11 includes a corner arc plate 112; the connecting assembly 12 is arranged on the box body 11, and the connecting assembly 12 includes an arc-shaped connecting plate 122, which is connected to the corner arc plate 112; the support column 124 is connected to the arc-shaped connecting plate 122; the upper cover 13 is arranged on the box body 11 and connected to the support column 124.

[0053] The housing assembly 1 of the present invention is applied to the inverter 2. The housing assembly 1 includes a box body 11, a connecting assembly 12 and an upper cover 13.

The support column 124 is connected to the arc-shaped connecting plate 122. The upper cover 13 is arranged on the box body 11 and connected to the support column 124. The housing assembly 1 of the present invention arranges the upper cover 13 on the box body 11 and supports and fixes it through the support column 124. There is no need to turn outward the edges of the box body 11 and the upper cover 13 that are fastened together as in the prior art. The box body 11 or the upper cover 13 is simple to form. In addition, the rounded corners of the box body 11 are effectively utilized, and the internal space of the inverter 2 is minimized.

[0054] In some technical solutions, optionally, as Figure 9 and Figure 15 As shown, the housing assembly 1 further includes a sealing ring 14 , which is disposed between the support column 124 and the upper cover 13 and is used to seal the gap between the support column 124 and the upper cover 13 .

[0055] In this technical solution, the connection gap between the support column 124 and the upper cover 13 is sealed by the sealing ring 14, which can prevent dust and impurities from entering the inverter 2 through the connection gap, thereby improving the service life of the electronic components 22 inside the inverter 2.

The annular sealing ring is arranged around the conductive boss 1242. The upper cover 13 includes a conductive protrusion 132, and the conductive protrusion 132 contacts the conductive boss 1242 to electrically connect the upper cover 13 to the support column 124.

[0057] In this technical solution, conductive bosses 1242 are provided on support columns 124, and conductive protrusions 132 are provided on upper cover 13. Thus, conductive bosses 1242 contact conductive protrusions 132, thereby achieving electrical connection between upper cover 13 and support columns 124, and thus enabling signal transmission between upper cover 13 and electronic components 22 within inverter 2. Optionally, the thickness of the annular sealing ring is 1mm to 2mm greater than the thickness of conductive bosses 1242. This allows the annular sealing ring to deform slightly under pressure during assembly of upper cover 13, improving sealing efficiency while ensuring good contact between conductive bosses 1242 and conductive protrusions 132, thus ensuring stable electrical connection.

[0062] In this technical solution, first connection holes 162 are provided on the upper cover 13 and the conductive protrusion 132, and locking holes 164 are provided on the conductive boss 1242. Thus, a first locking member 166 passes through the first connection hole 162 and engages with the locking hole 164 to secure the upper cover 13 to the support column 124. By integrating the fixing, sealing, and electrical connection functions of the box body 11 and the upper cover 13, this utility model frees up space in the box body 11 while strengthening the box body 11.

The shape of the arc segment 1222 matches the shape of the corner arc plate 112, providing better support, while the straight segment 1224 is easier to connect with the side plate 114, thereby making it easier to assemble the arc-shaped connecting plate 122 to the box body 11 and improving the supporting strength of the arc-shaped connecting plate 122. Among them, the mounting column 11422 can be a stud, and the second locking member 11424 can be a nut.

[0074] The following describes an inverter 2 of the present invention from another embodiment, including:

[0075] The box 11 is used to install and fix the main control circuit, heat dissipation device and inductor box of the inverter 2;

[0076] The upper cover 13 is provided on the upper side of the box body 11 and is used to seal the box body 11;

The connecting component 12 and the box body 11 have arc sections 1222 of the same structure at the four corners, which are used to fit with the box body 11 after being fixed, and play a role in moment bearing and supporting. The connecting component 12 is fixed to the box body 11 through a circular hole and a waist-shaped hole. The force of the support column 124 is borne by the arc section 1222 and the reinforcement rib 126 on the structural frame.

[0085] Due to the design of the drawing die, the four corners of the box 11 are circular, with riveted mounting posts 11422 on both sides of the arc.
