Middle frame, electronic device, and method for manufacturing middle frame
A middle frame includes an inner frame, a blocking member, and a covering member. The inner frame includes an outer surface and an inner surface opposite the outer surface. The inner frame further comprises at least one mounting hole penetrating the outer surface and the inner surface, the at least one mounting hole comprises an opening at the outer surface. The covering member covers the outer surface, and the blocking member is disposed between the covering member and the outer surface so as to cover the opening of the at least one mounting hole at the outer surface. An electronic device including the middle frame and a method for manufacturing the middle frame are also provided.
1. A middle frame comprising:
an inner frame comprising an outer surface and an inner surface opposite the outer surface, the inner frame further comprising at least one mounting hole penetrating the outer surface and the inner surface, the at least one mounting hole comprising an opening at the outer surface;
a covering member covering the outer surface; and
a blocking member disposed between the covering member and the outer surface, the blocking member covering the opening;
wherein the outer surface is recessed toward the inner surface to form a groove, the opening is disposed at a bottom of the groove, and the blocking member is disposed in the groove.
2. The middle frame of claim 1 , wherein in a direction perpendicular to a central axis of the opening, a thickness of the blocking member is not more than a depth of the groove.
3. The middle frame of claim 1 , wherein a gap is formed between the blocking member and an inner wall of the groove.
4. The middle frame of claim 1 , wherein the blocking member is made of at least one of aluminum, copper, and iron.
5. The middle frame of claim 1 , wherein the at least one mounting hole is a threaded hole.
6. An electronic device comprising:
a middle frame comprising:
an inner frame comprising an outer surface and an inner surface opposite the outer surface, the inner frame further comprising at least one mounting hole penetrating the outer surface and the inner surface, each of the at least one mounting hole comprising an opening at the outer surface;
a covering member covering the outer surface; and
a blocking member disposed between the covering member and the outer surface, the blocking member covering the opening;
wherein the outer surface is recessed toward the inner surface to form a groove, the opening is disposed at a bottom of the groove, and the blocking member is disposed in the groove.
7. The electronic device of claim 6 , wherein in a direction perpendicular to a central axis of the opening, a thickness of the blocking member is not more than a depth of the groove.
8. The electronic device of claim 6 , wherein a gap is formed between the blocking member and an inner wall of the groove.
9. The electronic device of claim 6 , wherein the blocking member is made of at least one of aluminum, copper, and iron.
10. The electronic device of claim 6 , wherein the at least one mounting hole is a threaded hole.
