Expert in structural design and manufacturing of mobile phone slide rail-Analysis of Meng Qi's design requirements for mobile phone slide rail

At present, the common types in the market are: straight sliding (divided into single sliding and double sliding) and side sliding.

A, single slide is only sliding in one direction, which is the most common. At present, most mobile phones on the market are single slide. For the mobile phone slide rail of Sony Ericsson W955 type, which is set according to the screen size and the size of the whole machine, Meng Qi can choose the following SMS-66SMS-ZH-2128SMS-ZH-2131SMS-ZH-183SMS-ZH-1686SMS-ZH-2134SMS, S-.

B, double sliding series, which can slide up and down. For example, Nokia N86, the slide-up is an ordinary slide phone, and the slide-down is an entertainment phone. This structure requires the slide rail to slide in both directions. And that overall structure of the slide rail of the mobile phone should not be too thick. Meng Qi model SMS-86 is the mobile phone slide rail,

C and sideslip series, which, as the name implies, slides away from the side. Like Nokia 676S or motorcycle milestone. Sms-ch-2433 SMS-ch-2825 SMS-ch-163

d, sideslip+upswing series, after sliding away from the side, can be upsloped and stand sideways, like Nokia N97 series.

E, up-slide+side-slide series, there are few models of this type on the market at present, because the structure of the slide rail and other matching parts are required to have high precision and high risk, so many mobile phone manufacturers are waiting to see this scheme for the time being, which may be a big selling point after the relevant technology matures.

F, slide up+horizontal screen, which is this type. At present, many solution providers just want to discuss the technology, and mobile phone manufacturers are also waiting to see for the time being. This structure requires complex structural accuracy and processing technology of the mobile phone slide rail.

Second, the structural form analysis of the slide cover machine;

slide cover machine is divided into slide cover part and main machine part. The slide cover machine evolved from a straight plate machine, which is composed of two straight plates stacked together, but the workload and difficulty of making the structure are equivalent to that of a semi-straight plate machine, and most of the structures are the same as those of the straight plate machine. The different structural design points are explained in detail later.

A, the shell material of the sliding cover is mainly divided into a shell and b shell. The motherboard of the sliding cover part includes screen, receiver, navigation key OK key and function key, camera, speaker, motor, magnet (fixed on the B shell) and other components

B, the shell material of the host part is mainly divided into C shell, D shell and battery cover. The motherboard of the host part includes MIC, Hall element, numeric keys, antenna, USB connector, SIM card, TF card, battery and other elements. Of course, the speaker and camera can be in the host part.

C, the mobile phone slide rail has evolved to replace the traditional BC case. So it is also called BC shell slide rail for short.
