Description

Technical Field

[0001] The present invention belongs to the technical field of mobile phone devices, and particularly relates to a usage method of a telescopic mobile phone. Background Art

[0002] With the rapid development of mobile communication technology, smart phones have become multi-functional terminal devices integrating information processing, audio-visual entertainment, and mobile office. The contradiction between users' demand for large-screen display and portability requirements has become increasingly prominent: on the one hand, large-size screens have significant advantages in video playback, game interaction, and multi-task processing; on the other hand, overly large device sizes will lead to problems such as decreased holding comfort and inconvenience in carrying.

[0003] In the prior art, flexible displays and folding screen structures achieve screen unfolding through hinge mechanisms, but there are still obvious limitations: firstly, the device thickness doubles in the folded state, affecting the single-handed holding experience; secondly, the mechanical rotating shaft structure occupies about 15%-20% of the internal space, restricting the battery capacity and the layout of the heat dissipation module; thirdly, the screen creases and mechanical wear caused by repeated bending significantly reduce the product reliability. Experimental data shows that the folding life is generally less than 200,000 times.

[0004] There is also a scroll screen design solution that uses a horizontal stretching structure. Although it can achieve screen size expansion, there are the following technical defects: 1. The stretching mechanism occupies the horizontal space, resulting in an over-standard body width; 2. The friction coefficient between the screen support layer and the sliding track is unstable, easily causing asynchronous stretching; 3. The dustproof and sealing level is difficult to reach the IP68 standard, and the intrusion of fine particles is likely to cause mechanical jamming. There are still three major technical bottlenecks in the current field of telescopic mobile terminals: ① The optimization ratio problem of the telescopic stroke and the body size. The existing structures are difficult to maintain structural stability within the telescopic range; ② The control accuracy of the screen tension balance during the dynamic stretching process is insufficient, easily causing screen distortion. These problems seriously restrict the commercialization process of telescopic electronic devices. Summary of the Invention

[0005] In view of this, the present invention aims to propose a usage method of a telescopic mobile phone to solve the problem of the optimization ratio of the telescopic stroke and the body size of the existing telescopic mobile phone, and the problem that the existing structures are difficult to maintain structural stability within the telescopic range.

[0009] Step 3: The telescopic movement of the back panel drives the telescopic movement of the phone screen. When the screen completely extends out of the housing, the user starts to use the phone;

[0010] Step 4: After use, by reversing the motor, the telescopic mechanism drives the back panel to move towards the inside of the housing to realize the retraction of the screen.

[0011] Furthermore, the telescopic mechanism includes a rack, a first gear, a gear shaft and a main shaft. The main shaft is connected to the motor.

Second gears are installed at both ends of the upper turning shaft and the lower turning shaft. The second gears are meshed and connected with the first gear.

[0013] Furthermore, the back panel is connected to the main shaft through a back panel connecting member.

[0014] Furthermore, a support member is installed below the back panel connecting member. A connecting member is provided at the end of the support member. The connecting member is rotatably connected to the outside of the main shaft.

[0015] Furthermore, the support member is made of a flexible material

[0016] Furthermore, the screen from outside to inside is a protective layer, a touch layer, a packaging layer, a display layer and a substrate in sequence.
