With reference to fig. 1 to 3, an embodiment of the present disclosure provides an enclosure for a panel, including a frame portion 10 and a plastic portion 20, where the frame portion 10 includes a main body 101, and a boss 102 extends outward from a side surface of the main body 101; the plastic part 20 is fixed to the main body 101 and wraps the boss 102. As shown in connection with fig. 1 and 2.

By adopting the embodiment, the plastic part 20 of the housing is assembled and molded with the frame part 10 through injection molding, and the boss 102 is wrapped by the injection molded plastic part 20, so that the plastic part 20 and the main body 101 of the frame part can be fixed, and the boss 102 can inhibit the shrinkage of the outer surface formed by the plastic part 20, so that the outer surface 201 of the plastic part keeps the shape after injection molding, and the purpose of leveling the outer surface of the housing is achieved.

The main body 101 of the frame portion 10 is a square frame, and the main body 101 includes an outer surface, an inner surface, and two side surfaces. Wherein the boss 102 is located at one of the side surfaces of the main body 101. The plastic part 20 is fixed to the main body 101, that is, the plastic part 20 is attached to and fixed to a side surface of the main body 101. The plastic part 20 covers the side of the main body 101 and is adapted to the side of the main body 101. In addition, the outer surface of the housing includes the outer surface 1011 of the main body and the outer surface 201 of the plastic part.

Optionally, the side of the body 101 includes a plurality of regions, some or all of which extend outward with bosses 102. In this way, the boss 102 is wrapped by the injection-molded plastic part 20, so that not only can the plastic part 20 be fixed to the main body 101 of the frame part, but also the outer surface formed by the plastic part 20 can be restrained from shrinking by the boss 102, and the outer surface 201 of the plastic part can keep the shape after injection molding.

In some embodiments, in the case that the boss 102 extends outward in a partial region, a region where the boss 102 is provided and a region where the boss 102 is not provided are spaced apart. In this way, the plastic part 20 wraps the bosses 102 and is equivalent to a gap embedded between adjacent bosses 102, which is beneficial to improving the stability and reliability of connection between the plastic part 20 and the frame part 10.

Alternatively, the boss 102 may have a semi-circular or square cross-section. Under the condition that the cross section of the boss 102 is semicircular, the plastic part 20 can be favorable for wrapping the boss 102, and the gap between the plastic part and the boss 102 is reduced. In the case where the boss 102 has a square cross section, after the plastic part 20 is injection-molded, the square boss 102 can more effectively suppress shrinkage of the plastic part 20 during cooling after injection-molding.

Optionally, the distance between the boss 102 and the outer surface 1011 of the body is a set value. The boss 102 having a set value away from the outer surface 1011 of the main body functions when the plastic part 20 is injection-cooled, and suppresses shrinkage of the outer surface 201 of the plastic part. In practical applications, the distance between the boss 102 and the outer surface 1011 of the main body may be set by a manufacturer according to practical situations. For example, different widths of the sides of the body 101 may result in different distances between the boss 102 and the outer surface 1011 of the body; the different thicknesses of the plastic portion 20 may result in different distances between the boss 102 and the outer surface 1011 of the main body.

In practical applications, the plastic part 20 is fixed to the main body 101, and it is understood that the plastic part 20 is directly injected as a part of a production mold of the main body 101, so that the plastic part 20 and the main body 101 are integrally molded. This not only contributes to improving the stability of connection between the plastic part 20 and the main body 101, but also can overcome the problem that the joint surface between the plastic part 20 and the frame part 10 has a gap or a step due to dimensional tolerance during assembly. In addition, the plastic part 20 can be adhered to the main body 101, so that the plastic part 20 and the main body 101 are fixed.

Under the condition that the bosses 102 are arranged on the first surface, the second surface, the third surface and the fourth surface, the connection between the plastic part 20 and the main body 101 is more reliable. In addition, a part or the whole area of the first face is provided with bosses 102. Similarly, the bosses 102 are provided on part or all of the second, third and fourth surfaces.

In the case where the boss 102 extends outward in a partial region of the first face, a region where the boss is provided and a region where the boss is not provided are spaced apart. In this way, the plastic part 20 wraps the bosses 102 and is equivalent to a gap embedded between adjacent bosses 102, which is beneficial to improving the stability and reliability of connection between the plastic part 20 and the frame part 10. Similarly, in the case where the boss 102 is provided in a partial region of the second surface, the third surface, and the fourth surface, a region provided with the boss and a region not provided with the boss are provided at an interval. In this way, the plastic part 20 wraps the bosses 102 and is equivalent to a gap embedded between adjacent bosses 102, which is beneficial to improving the stability and reliability of connection between the plastic part 20 and the frame part 10.
