A structure and method for preventing mobile terminal protective cover from turning over and closing the screen

Abstract

The invention discloses a structure and a method for preventing a mobile terminal protective jacket from being turned over and turning a screen off. A Hall inductive switch is arranged on one side inside a mobile terminal body; an induced magnet is embedded at a position on one side, which is opposite to the position of the Hall inductive switch on one side inside the mobile terminal body, inside a protective jacket cover body; a tinplate is jointed to the upper part of the induced magnet embedded into the protective jacket cover body. When the surface of a mobile terminal screen is covered by the mobile terminal protective jacket, the Hall inductive switch inside the mobile terminal body can be triggered by the induced magnet without being influenced by the tinplate. When the mobile terminal protective jacket is turned over to the back side of a mobile terminal, the tinplate is positioned between the Hall inductive switch and the induced magnet, and the Gaussian value of the SN pole of the induced magnet is tilted by using the magnetic conduction characteristic of the tinplate, so that the magnetic induction intensity on the Hall inductive switch is changed. The Hall inductive switch is not turned off when the mobile terminal protective jacket is turned over to the back side of the mobile terminal, so that the mobile terminal screen is prevented from being turned off, and normal use of a user is ensured.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to a structure and method for preventing a mobile terminal protective case from turning over and closing the screen. Background technique [0002] At present, smart mobile terminal devices have been widely used by people, and the screens of smart mobile terminals such as smart phones and tablet computers are getting bigger and bigger, and there are more and more protective leather cases for protecting the screen and the housing. In the prior art, when the protective cover is opened, the screen of the device needs to be turned on to start the device, and when the cover is closed, the screen of the device needs to be turned off to save power. One of the protective covers, the magnet protective cover, is designed with a Hall switch for sensing Take the switch screen, take the mobile phone as an example, figure 2 Shown is the cross-sectional structure of a mobile phone with a magnet protect...

Problems solved by technology

In the prior art, when the protective cover is opened, the screen of the device needs to be turned on to start the device, and when the cover is closed, the screen of the device needs to be turned off to save power. One of the protective covers, the magnet protective cover, is designed with a Hall switch for sensing Take the switch screen, take the mobile phone as an example, figure 2 Shown is the cross-sectional structure of a mobile phone with a magnet protective cover installed in the prior art. The inner side of the mobile phone body 10' is opposite to the inner side of the magnetic protective cover 20', and a Hall sensor switch 30' and a magnet 201' are respectively installed. When the cover body 20' of the magnetic protective cover is turned over to the screen surface of the mobile phone body 10', the Hall sensor switch 30' is triggered by the magnetic induction of the magnet 201' on its upper part to turn off the screen, and when the user opens the protective cover of the magnet to use the mobile phone , the cover body 20' of the magnet protection cover is flipped to the back of the mobile phone body 10'. At this time, since the magnet 201' is located at the lower part relative to the Hall sensor switch 30', the Hall sensor switch 30' will also be triggered by magnetic induction to turn off the screen. , when the user needs to use the mobile phone, the screen is turned off due to the magnet on the magnetic protective cover, which seriously affects the user's use
