Abstract

The invention discloses a middle frame and a making method thereof, and an electronic device; the method comprises the following steps: preprocessing a metal base material so as to form frame prefabricated slabs, wherein slots are formed on the inner side wall of the frame prefabricated slab; providing a middle plate, and forming a plurality of bumps arranged at intervals on the side wall of the middle plate; assembling the bumps into the slots so as to set the plurality of frame prefabricated slabs around the periphery of the middle plate, and using the plurality of frame prefabricated slabsto form an annular outer frame that encircles the middle plate, thus obtaining the middle frame. The method can effectively improve the raw material utilization rate, can save raw materials, can reduce production costs, can reduce processing time, can improve production efficiency, and can simplify the solidification process.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a middle frame, a preparation method thereof, and an electronic equipment. Background technique [0002] In the field of electronic equipment, with the rapid development of materials, electronics and other technologies, the functions of electronic equipment are becoming more and more diversified, and the competition is becoming more intense. The requirements for the strength of the middle frame of electronic equipment are getting higher and higher. Therefore, in order to enhance the overall strength of electronic devices such as mobile terminals and improve user tactile experience, mobile terminals have adopted metal middle frames on a large scale. The metal middle frame is drop-resistant, corrosion-resistant, and has a metallic texture. It feels delicate and wear-resistant, and can be used directly as the side frame of a mobile phone. [0003] However, the current middle fra...
