Support frame

Abstract

The invention discloses a support frame supporting a mobile phone keyboard. The support frame comprises a metal frame and a plastic body combined with the metal frame. The metal frame is platy and has a first bearing surface; and the plastic body has a second bearing surface. The metal frame has a plate body part and at least one protruding part extended from one end of the plate body part, wherein the thickness of the protruding part is smaller than that of the plate body part and the protruding part is combined with the plastic body in an embedment forming mode, so the structure of the support frame is stable and the coplanarity of the first and second bearing surface is ensured to bear the keyboard stably.

Description

【Technical field】 [0001] The invention relates to a support frame, especially a support frame used in electronic products to support components. 【Background technique】 [0002] In mobile phone products, a support frame is usually used to carry the keyboard of the mobile phone. The support frame generally includes a metal frame and a plastic body that are combined with each other, wherein the metal frame is the main part that carries the keyboard, and the plastic body connects and holds the support frame with the casing part of the mobile phone while carrying the keyboard, so as to achieve the keyboard. The purpose of stably holding in the mobile phone. In the above supporting frame, usually the metal frame and the plastic body are combined at the edge by insert molding to realize the fixing of the two. However, in the embedded molding process, in order to ensure the stable combination of the metal frame and the plastic body, the edge of the joint of the plastic body is usu...

Problems solved by technology

[0007] Compared with the prior art, the support frame of the present invention has the following beneficial effects: by providing a protrusion on the metal frame, and the upper surface of the protrusion is lower than the first bearing surface, the plastic body can wrap the protrusion and the metal When the frame is combined, the first load-bearing surface and the second load-bearing surface can be guaranteed to be coplanar, which solves the problem that the metal frame and the plastic body are not in the same plane and are easy to detach due to insufficient bonding force in the prior art, so that the support frame can be placed on the metal frame coplanar with the plastic body while still being structurally stable
