Telescopic mobile terminal

Abstract

The invention discloses a telescopic mobile terminal. An executing mechanism used for driving the functional assembly to do linear motion is further arranged in the cavity; the executing mechanism comprises a driving shaft, a torsional spring and a first groove formed in the bottom of the shell. The driving shaft comprises a rotating shaft and a square head which are fixedly arranged in sequence from top to bottom; a cam is installed at the top end of the rotating shaft, a pin A is fixedly arranged at the top of a protruding part of the cam, a first connecting rod is hinged to the pin A, a pinB is fixedly arranged on the bottom surface of the other end of the first connecting rod, a second connecting rod is hinged to the pin B, the other end of the second connecting rod is hinged to the functional assembly, and the rotating shaft is sleeved with a torsional spring. The executing mechanism further comprises an iron block and a magnet; the iron block and the magnet are both arranged inthe first groove, the iron block is fixedly arranged at the right end of the square head, and the magnet is fixedly arranged on the left side wall of the first groove. The beneficial effects of the invention are that the structure is compact, the manufacturing cost is low, the service life is long, the maintenance of functional devices is facilitated, and the diversity of user experience is improved.

Description

Technical field [0001] The invention relates to the technical field of mobile terminal structures, in particular to a telescopic mobile terminal. Background technique [0002] At present, with the development of mobile terminals, people are increasingly unable to meet the commonly used mobile terminal structure. How to design a mobile terminal with diversified structures and functions to improve user experience has become one of the key goals of researchers. The existing mobile terminal includes a casing and a display screen. The display screen is fixed on the top of the casing. A molding cavity is enclosed between the display screen and the casing. The casing is provided with functional components and power modules. It is any one of camera module, iris recognition module, face recognition module, fingerprint recognition module, flash, photosensitive sensor, receiver, and microphone. The functional components are available for users to use, because the functional components are ...

Problems solved by technology

[0004] However, although this mobile terminal can extend the functional components from the housing, it still has the following defects: 1. When the user presses the first driver 223 and the second driver 224 at the same time, if the force is too large, it will cause an arc. Shaped shrapnel 222 is broken, thereby reducing the service life of the mobile terminal

II. After the user extends the functional components from the housing, the user still needs to hold the first driver 223 and the second driver 224 to prevent the arc-shaped shrapnel 222 from resetting, which will undoubtedly cause the user to have no idle hands. to operate the display, reducing the diversity of the user experience

III. The functional devices in the functional components are encapsulated in the sliding seat of the functional component. When maintenance or replacement of functional devices is required, maintenance personnel are required to disassemble the sliding seat first, and then take out the damaged functional device from the sliding seat. Only in this way can it be convenient for maintenance personnel to maintain functional devices, which undoubtedly delays maintenance time and reduces maintenance efficiency
