[0051] As the application scenarios of engineering equipment expand, there is an increasing demand for electric control boxes with high reliability. The protection level of the electric control box is related to the service life of the engineering equipment, and is the most basic guarantee for the long-term reliability of key control electronic components.

[0052] The electric control box in the related art is usually composed of a thin-walled metal structure, such as sheet metal. The sheet metal electric control box can resist external environmental electromagnetic interference and effectively protect electronic components from external environmental erosion for a long time.

[0053] But the sheet metal structure generally needs to be welded, polished, and painted with high energy consumption and high pollution process to obtain high-grade sealing, which requires high economic cost and is difficult to meet the needs of green market development.

[0054] Therefore, in one aspect of the present disclosure, an electric appliance box is provided, which can improve the sealing performance and help reduce the energy consumption of production and manufacturing.

[0055] Figure 1 is a structural schematic diagram of some embodiments of the electric appliance box according to the present disclosure, Figure 2 is a structural exploded schematic diagram of some embodiments of the electric appliance box according to the present disclosure, Figure 3 is a rear view of some embodiments of the electric appliance box according to the present disclosure, Figure 4 is a side view of some embodiments of the electric appliance box according to the present disclosure, with reference to Figures 1-4 In some embodiments, the electric appliance box includes a box body assembly 1 and a top cover 2.

A first line sealing structure 3 is arranged on the inner side edge of the top cover 2, and the top cover 2 is connected to the top of the box body assembly 1 through the first line sealing structure 3.

[0057] The top cover 2 is buckled on the outer periphery of the top of the box body assembly 1 to form a closed containing space with the box body assembly 1. The containing space can be placed with items with sealing storage requirements, such as electronic control elements, so as to prevent the items in the containing space from being eroded by the external environment.

[0058] The first line sealing structure 3 extends along the inner side of the top cover 2. When the top cover 2 is connected to the box body assembly 1, the first line sealing structure 3 is located between the gap between the top cover 2 and the box body assembly 1, forming a reliable line contact.

[0059] In the present embodiment, by arranging the first line sealing structure 3 on the inner side of the top cover 2, the gap between the contact surface of the top cover 2 and the box body assembly 1 can be reduced, the risk of external water or other pollutants invading the containing space can be reduced, and the sealing performance of the electric appliance box can be improved.

[0060] Since the electric appliance box in the present embodiment has the first line sealing structure 3, it can achieve high sealing performance without using continuous welding to weld the top cover 2 and the box body assembly 1, thereby allowing the electric appliance box to be produced in a intermittent spot welding manner with lower power consumption and higher efficiency, and reducing pollution generated in the production process.

[0061] With reference to Figures 1-4In some embodiments, the box assembly 1 comprises a main box 11, a side cover 12 and a base 13. The top of the main box 11 is fixedly connected with the top cover 2, the side cover 12 is detachably connected with the main box 11, and the base 13 is fixedly connected with the bottom of the main box 11.

[0062] The main box 11 comprises, but is not limited to, a bending type, having one end surface parallel to the side cover 12 and two end surfaces perpendicular to the side cover 12. The shape of the main box 11 can be adaptively adjusted according to the shape of the contained articles.

[0063] The base 13 comprises a bottom plate and an insertion structure connected with the bottom plate. The insertion structure is at an angle with the bottom plate, so as to be connected with the inner wall of the main box 11 through the insertion structure, reducing the assembly gap between the base 13 and the main box 11.

The protruding rib protrudes and extends relative to the inner side of the top cover 2 towards the direction close to the top edge of the main box 11, so that the top cover 2 is intermittently connected with the outer edge of the top of the main box 11 by the protruding rib. The insertion structure of the base 13 is intermittently spot welded with the inner wall of the main box 11.

[0067] The installation gap between the top cover 2 and the main box 11 is 0.9-0.98 times the height of the protruding rib, so as to ensure that the protruding rib and the main box 11 form reliable line contact, reduce the contact surface between the two parts, and inhibit the uneven leakage gap caused by irregular contact of the actual part surface. The height of the protruding rib refers to the distance that the protruding rib extends from the inner side of the top cover 2 relative to the outer side of the main box 11.

[0068] In the embodiment, the first line sealing structure 3 forms a reliable seal between the top cover 2 and the main box 11, so that the main box 11 can be intermittently spot welded with the top cover 2. Compared with the form of continuous electric welding, the problem of unreliable sealing caused by welding defects of electric welding can be compensated for, higher production efficiency can be achieved, less pollution can be generated, and high-grade sealing performance can be achieved while meeting the economic requirements.
