It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figures 1 to 6 The high-strength chassis structure and electrical equipment provided by this utility model will now be described. The high-strength chassis structure includes a chassis body, which includes six interconnected panels. The connection between any two adjacent panels has a limiting abutment structure. The limiting abutment structure includes a groove 9 formed at the end of one of the panels. The groove 9 has its opening located on the inner sidewall of the panel and extends to the edge of the panel in the width direction. The end of the other panel is embedded in the groove 9 and abuts against the bottom of the groove 9. An L-shaped joint structure is formed between the two adjacent panels.

[0027] The high-strength chassis structure provided by this utility model, compared with the prior art, no longer uses sheet metal bending with poor strength to form the chassis body. Instead, it is assembled and connected by six boxes. The six boxes are spliced ​​and fixed separately, which improves the connection strength between the boxes and ensures the structural strength of the chassis body. Any two boxes are connected by a countersunk groove 9 of the limiting abutment structure. The bottom of the countersunk groove 9 forms a limiting step structure at the edge of the box. During installation, the edge of one of the two adjacent boxes abuts into the countersunk groove 9 of the other box, forming an L-shaped joint structure between the two adjacent boxes. The L-shaped joint structure further improves the connection strength of the boxes. In addition, the L-shaped joint structure reduces the gap between the boxes, thereby effectively reducing electromagnetic leakage.

[0028] In some possible embodiments, please refer to Figure 1 , Figure 5 and Figure 6The six boxes include four side boxes and two end boxes. The four side boxes form a rectangular cylindrical structure. The front and rear faces of the rectangular cylindrical structure are used to connect the two end boxes, respectively. The four side boxes have grooves 9 at both the front and rear ends. The four grooves 9 at the same end are connected in sequence to form an annular limiting groove structure.
