Problems solved by technology

[0006] 1) During the frequent mechanical movement of the upper cover, the flexible circuit board is easily damaged, and the connectors at both ends are also easy to loosen and fall off. At present, a large part of the failures in mobile phone maintenance are caused by the problems of the flexible circuit board
[0007] 2) The structural design of folding and sliding mobile phones is relatively complicated. The LCD on the top cover needs more than 20 signal lines. If a camera (such as a camera) is also installed on the top cover, about 20 signal lines are needed. Therefore, for different designs, different connectors and flexible circuit boards need to be customized for mobile phones, which brings more workload to the design and takes more time
[0008] 3) In the design of mobile phones, different connection circuit boards are usually used for different models of mobile phones. Therefore, the consistency of the system is poor, which is not conducive to the standardization of mobile phone products

Embodiment Construction

[0020] Next, the mobile phone of the present invention and the method for realizing the connection of the upper and lower covers thereof will be described in detail in conjunction with accompanying drawings 1 to 4 .

[0021] Since the flexible circuit board transmits the signals for communication between the digital logic devices in the upper and lower covers, and the signals transmitted between the digital logic devices are all digital signals, it is possible to use wireless communication to replace traditional cables. Realize signal communication between devices. To realize the transmission of digital logic signals by wireless communication, three problems need to be solved: (1) acquisition of output signals; (2) transmission of signals using short-distance wireless channels; (3) analysis of wireless received data and signal recovery.

[0022] Therefore, the basic principle of the present invention is to use short-distance wireless communication technology to transmit the si...

Abstract

The present invention discloses a handset as well as a method for connecting its upper and lower cover. The method includes the following steps: setting radio communication unit on the two cover board separately, step 101: a first cover board transmits signal to a second cover board with radio mode through the radio communication unit of the first cover board; step 102: the second cover board receives the radio signal through the radio communication unit. According to the implementing method of the handset as well as its upper and lower cover connection, implementing signal communication of various components of the communication device, and avoiding the problem that the linker and cable is easy to occur physical damage.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a mobile phone and a method for realizing the connection between upper and lower cover plates thereof. Background technique [0002] Currently, folding and sliding mobile phones are quite popular among consumers in the market. Although folding and sliding mobile phones are not very different in terms of hardware and software design compared with bar-type phones, they are more troublesome than bar-type phones in terms of structural design. This is mainly because folding and sliding mobile phones are structurally divided into two parts, the upper cover and the lower cover. [0003] Among them, the upper cover is generally equipped with display devices, touch screens, audio input and output units, cameras, some keyboards and other devices, wherein the display device can be a thin film transistor liquid crystal display (Thin FilmTransistor Liquid Crystal Displayer, LCD); the l...
