Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal or, more particularly, to an open/close detection device for a mobile terminal and a mobile terminal. BACKGROUND OF THE INVENTION With the continuous reduction of the size of mobile terminals, in the industry, portable folding machines (i.e., clamshell machines), slider machines, and capping machines are very popular on mobile terminal (e.g., mobile phone) devices. In general, the detection of opening and closing (i.e., opening or closing) of a slide or folding mobile phone is based on a mechanical detecting device or an electronic detecting device, wherein the electronic detecting device is most commonly detected by a Hall switching device. Taking the slider machine as an example, the opening and closing detection method is as follows. The magnet is mounted on the upper sliding body that can slide up and down, and the Hall switch device is mounted on the main body at a position corresponding to the magnet mounting position, and the two are used together. The signal is in a pull-up state. When the slider is opened, the Hall switch device outputs a high level signal. When the two devices are close, that is, when the upper slider is combined with the host, the Hall switch device outputs a low level signal. When the control chip detects the high and low level signals, it can judge the open and closed state of the upper sliding body in the mobile terminal at this time. At present, the industry's solutions for opening and closing tests mainly include:

(1) Mechanical detection scheme A mechanical switch is installed in the moving track of the mobile phone moving body. When the mobile body is opened or closed, the mechanical switch is triggered to cause a change in the level signal of the detection circuit, thereby judging the state of the moving body. However, since the stability of the scheme is not as good as that of the electronic detecting device, it is currently used less in the industry.

(2) The electric signal detection scheme installs the Hall switch device and the magnet at a position corresponding to the main body and the moving body. When the two devices are close, the magnetic force generated by the magnet acts on the Hall switch device, so that the Hall switch device outputs Low level signal; Since the signal is pulled up, when the sliding part is opened, no magnet magnetic force acts on the Hall switching device, the Hall device outputs a high level signal, and the control chip detects a high and low level signal, thereby judging At this time, the mobile terminal is in an open and closed state in the mobile terminal. However, this solution requires the use of a Hall switching device and a magnet. Generally, the moving body is thin, and adding a magnet in the moving body takes up space and increases the hardware cost. The utility model relates to the problem that the magnet in the mobile body can occupy space and increase the hardware cost in the related art, and the main object of the present invention is to provide a mobile terminal and a mobile terminal opening and closing detecting device, to solve the above problems at least one. According to an aspect of the present invention, a mobile terminal is provided. The mobile terminal includes: a Hall switch device and a squad, in addition to the mobile body and the host body, wherein the Hall switch device is located on the mobile body and the host body.
