Description
Technical Field
The present invention relates to a mobile phone, and more particularly, to a flip structure of a mobile phone.
Background
Flip phones still have certain needs in the current mobile phone market due to their unique design in profile and more ergonomic shape. Especially in elderly people, the demand for clamshell machines is still high. Moreover, with the popularization of smart phones, a flip smart phone is slowly popular, which is different from a conventional flip smart phone, and since the smart phone needs to be matched with a large-sized display screen and a large-sized touch screen, the smart flip smart phone is often designed to be too thick and heavy.
The intelligent flip phone has the advantages that the whole phone body is heavier, and the flip part is heavier than a conventional flip phone, so that the rotating shaft structure of the flip phone has higher requirements on structural strength and service life.
At present, the structure design of the existing cover turning machine at the rotating shaft is that the rotating shaft and the shell are integrated, but due to the consideration of disassembly and manufacturing feasibility, the strength of the root part of the cantilever is weak when the rotating shaft is stressed in rotation, and fatigue fracture is easy to occur.
Fig. 1a and 1b are schematic diagrams showing two structural detachable forms of a flip part of a current flip phone. As shown in fig. 1a and 1b, the rotating shaft sleeve part of the rotating shaft is integrally formed with one of the shells in both the structural form a and the structural form b. As can be seen from fig. 1a, the rotating shaft sleeve 21a is integrally formed with the front shell 22, when the whole flip is opened, the front shell 22 has an upward acting force, and through the principle of mechanics, the joint of the front shell 22 and the rotating shaft sleeve 21a absorbs the kinetic energy generated when the flip is opened, so that the joint of the front shell and the rotating shaft sleeve 21a is a stress concentration point, i.e., a weak point E, which may be fatigue-broken in the process of repeated opening and closing movements and impacts.
As can be seen from fig. 1b, the rotating shaft sleeve 21b is integrally formed with the lower shell 23, and although there is no weak point generated during the process of opening the flip, during the process of closing the flip, since the rear shell 23 has a downward acting force, the connection between the rear shell 23 and the rotating shaft sleeve 21b absorbs the kinetic energy generated during the closing of the flip through the principle of mechanics, so that the connection between the rear shell and the rotating shaft sleeve 21b is a stress concentration point, i.e., the weak point E, and during the repeated opening and closing movements and impacts, the weak point may also be fatigue-broken.
However, if the housing connected to the rotating shaft is made of a metal material, although the strength can be improved, since the flip phone has a large volume, the manufacturing cost of the flip phone using all metal is high and the weight of the flip phone is increased. And thus is not a good solution.
