CN108566454B - Middle frame and terminal - Google Patents

In the current terminal field, users have higher and higher requirements on various requirements of the terminal, especially requirements on the appearance of a mobile phone. As a new mobile phone material, the 3D glass cover plate has many advantages such as high hardness, wear resistance, and colorful surface color, and therefore, the 3D glass cover plate is widely used by various large mobile phone manufacturers, please refer to fig. 1, fig. 1 is a schematic connection diagram of a 3D

11 and a middle frame 12 in an existing mobile phone, because the upper surface of the middle frame in the existing mobile phone structure is a flat plane, and the edge of the 3D

11 is an arc surface, the 3D

11 and the middle frame 12 in the existing mobile phone structure are often assembled in a side connection manner, which results in that the 3D

11 and the middle frame 12 are difficult to form a tight fit, and a large gap is easily generated, if the mobile phone falls, a large impact is generated on the glass cover plate, and the reliability of the whole mobile phone is low.

33 is disposed on the

32, the supporting direction of the first supporting

331 of the first supporting

33 is directed to the side of the

331, and in the middle frame shown in fig. 3, a certain gap exists between the first supporting

33 and the

31, that is, the first supporting

33 is isolated from the

31, in this case, in order to make the first supporting

331 of the first supporting

33 better embody its supporting function, it is preferable that the

32 should be disposed along the area where the

31 is located. While only one first support member is provided on the middle plate of the middle frame adjacent to one of the side frames shown in fig. 3, it should be understood that in other embodiments, one first support member may be provided on the middle plate adjacent to the side of the other side frame opposite the one side frame.

31, and the area enclosed by the

31 is completely covered, in order to better dissipate heat of the components carried by the middle frame, the

32 may not completely cover the area enclosed by the

31, for example, as shown in fig. 3-2, the center of the

32 in fig. 3-2 is hollow (the area enclosed by the middle dotted line), and in some embodiments, some through holes may be disposed on the

32 to dissipate heat of the components. It should be noted that the

32, i.e. the

331 of the

33 may be arranged around one turn of the edge of the

32, the first support member not being shown in fig. 3-1 and 3-2.

In the above embodiments, the connecting ends of the first supporting

33 are all disposed in the

32, that is, the first supporting

33 may be disposed on the inner side of the

31, that is, the first supporting

33 may be connected to the

32 and the

31 at the same time, for example, as shown in fig. 4, the first connecting

33 may also be disposed on the inner side surface of the

31 and may be isolated from the middle plate, i.e., the first supporting

33 may not contact the middle plate. The middle frame in fig. 6 includes four side frames, and the first
