Mobile phone lateral hinge structure

The invention relates to a mobile phone lateral rotating shaft structure, in particular to a conventional coil spring which uses a reed spring, which can provide a strong force for a short actuating stroke, thereby reducing the lateral rotating shaft structure. The volume is reduced, and the volume of the lateral hinge structure is reduced, so that it can be disposed on the side of the side of the lower cover of the mobile phone, and the other side can be accommodated on the side of the lower cover.

Mobile phones are almost indispensable for everyone, and mobile phones are designed to meet different user preferences. The types of phones can be divided into: upright, slide, touch, flip and cap. Because of the advantages of large screen, large buttons and small storage capacity, the folding mobile phone is very popular among consumers. Please refer to Figure 1 and Figure 2. The flip-type mobile phone 98 is on the cover 981. Between the lower cover 982, the design side is driven to rotate the shaft, so that the folding mobile phone 98 can easily provide appropriate force to achieve the purpose of positioning during the process of covering the cover. The telephone lateral rotating shaft structure, wherein the lateral rotating shaft 9 has a double-end helical spring structural design, which comprises: an upper casing cover 91, a lubricating plate 92, an actuating cam 93, a cam slider 94, a positioning post 95, a coil spring 96 and The lower housing 97 has the following disadvantages:
