The cover is provided with a first flange, the first flange comprising a first bent edge spaced from and disposed opposite to the second surface, and the housing body is provided with a second flange, the second flange surrounding at least a portion of the circumference of the opening of the housing body, and the second flange comprising a second bent edge spaced from and disposed opposite to the second surface. The first bent edge and the second bent edge are stacked and connected on a side facing away from the first surface of the cover. This allows the cover to be pressed tightly against the housing body while avoiding damage or indentation to the exterior surface of the housing assembly, thereby making the exterior surface of the housing assembly smoother and thereby improving the waterproof performance of the housing assembly.

[0008] It can be understood that the first bent edge and the second bent edge are both arranged opposite to the second surface, that is, the first bent edge and the second bent edge are connected at the bottom of the cover body, and there is no need to screw on the first surface, thereby improving the integrity and aesthetics of the first surface. At the same time, the first bent edge and the second surface are spaced apart, so that the first bent edge and the second bent edge have a certain distance from the second surface, so that after the two are stacked and connected, no indentation will be generated on the cover body, further improving the strength, aesthetics and waterproofness of the first surface of the cover body.

[0050] It can be understood that the first bent edge 20 and the second bent edge 40 are both arranged opposite to the second surface 12, that is, the first bent edge 20 and the second bent edge 40 are connected at the bottom of the cover body 1, and there is no need to screw on the first surface 10, thereby improving the integrity and aesthetics of the first surface 10. At the same time, the first bent edge 20 and the second surface 12 are spaced apart, so that the first bent edge 20 and the second bent edge 40 have a certain distance from the second surface 12, so that after the two are stacked and connected, no indentation will be generated on the cover body 1, further improving the strength, aesthetics and waterproofness of the first surface 10 of the cover body 1.

The fourth bent edge 42 is bent in a direction away from the cover body 1, so that the fourth bent edge 42 extends in a direction away from the cover body 1, thereby making a distance between the second bent edge 40 and the cover body 1. In this way, the position of the first bent edge 20 and the position of the second bent edge 40 can be more adapted. After the first bent edge 20 is connected to the second bent edge 40, the connecting part can be prevented from generating indentations on the cover body 1, and the distance between the cover body 1 and the shell body 3 is reduced, which makes it easier to seal between the cover body 1 and the shell body 3.

[0087] In practical applications, compared to the prior art solutions that use stepped surfaces, the housing assembly proposed in this application has a simpler structure. The housing body 3 eliminates the original stepped surface, changes the bending direction of the flange, and adjusts the position of the sealing ring. This increases the strength of the bent portion of the cover 1, and the riveting operation is performed on the bent surface, which can avoid rivet marks on the front exterior surface.

[0088] Specifically, the shell assembly includes a sheet metal upper cover (such as the cover body 1) and a sheet metal shell (such as the shell body 3). The sheet metal upper cover needs to be riveted with a rivet nut 50 of corresponding size in advance and then bent into shape. The sealing ring (such as the seal 7) is fixed to the sheet metal upper cover by dispensing glue. During installation, the sheet metal upper cover needs to be buckled onto the sheet metal shell so that the edges are aligned, and then the entire machine is fine-tuned and locked according to the hole position.

[0089] In this utility model, the term "plurality" refers to two or more, unless otherwise specified. Terms such as "installed," "connected," "connected," and "fixed" should be interpreted broadly. For example, "connected" can refer to a fixed connection, a detachable connection, or an integral connection; "connected" can refer to a direct connection or an indirect connection through an intermediary.
