Problems solved by technology

[0005] The purpose of the present invention is to provide a detection method for the state of the leather case of the equipment, so as to solve the problem that when the leather case in the prior art is in the closed state, it is affected by the use time, and the leather case itself may be relatively easy to deform, so that the position of the magnetic block It may deviate from the position of the sensor, so that the sensor cannot normally sense the state of the device holster, which brings inconvenience to use

Embodiment 1

[0025] figure 1 It shows the implementation process of the detection of the state of the leather case of the device provided by the first embodiment of the present invention, and the details are as follows:

[0026] In step S101, the magnetic signal sensor disposed in the device detects the magnitude of the magnetic signal of the magnetic block disposed on the device leather case.

[0027] Specifically, the magnetic signal sensor may be a Hall sensor, and of course other sensors capable of inducing magnetic field signal strength may also be selected. Wherein, the Hall voltage of the Hall sensor changes with the change of the magnetic field strength, the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The Hall voltage value is very small, usually only a few millivolts, but the amplifier in the integrated circuit can amplify the voltage enough to detect the voltage signal.

[0028] As an improvement of the present ...

Embodiment 2

[0041] figure 2 It shows the implementation process of the method for detecting the state of the leather case of the device provided by the second embodiment of the present invention. The proximity sensor is an infrared proximity sensor, and the infrared proximity sensor includes an infrared transmitter and an infrared receiver. The method is described in detail as follows:

[0042] In step S201, the magnetic signal sensor disposed in the device detects the magnitude of the magnetic signal of the magnetic block disposed on the device leather case.

[0043]In step S202, if the magnetic signal sensor detects that the magnetic signal of the magnetic block disposed on the leather case of the device is less than a predetermined value, the infrared emitter emits an infrared signal, which is reflected and received by the infrared receiver.

[0044] The state of the device holster is detected by the infrared emitter and infrared receiver of the infrared proximity sensor. Since the d...

Embodiment 3

[0056] image 3 It shows the implementation process of the detection of the state of the device leather case provided by the third embodiment of the present invention, and the details are as follows:

[0057] In this embodiment, a capacitive contact sheet is provided on the leather case of the device, wherein steps S301 to S305 are the same as steps S201 to S205 in the second embodiment. figure 2 On the basis of the present invention, the embodiment of the present invention includes step S306 and step S307, which are described in detail as follows:

[0058] In step S306, if the acquired color belongs to the second color list unavailable for infrared detection, that is, does not belong to the first color list, it is detected whether the screen senses a touch instruction of the capacitive contact sheet.

[0059] Wherein, the second color list that cannot be used for infrared detection is a preset color that attracts infrared light strongly, such as dark colors such as dark bla...

Abstract

The invention belongs to the field of device accessories, and provides a method and device for detecting the state of a device leather case. The method includes the steps that a magnetic signal sensor arranged in a device detects the size of a magnetic signal of a magnetic block arranged on the device leather case; if the magnetic signal sensor detects that the magnetic signal of the magnetic block arranged on the device leather case is smaller than a predetermined value, the distance between the device leather case and a device screen can be detected through a proximity sensor; the state of the device leather case is determined according to the distance, detected by the proximity sensor, between the device leather case and the device screen. Compared with the prior art, the error detection defect happening when the magnetic block in the device leather case deviates from the position of the sensor in the prior art can be overcome, hence, the detecting accuracy of the device leather case can be improved, and using is more convenient.

Description

technical field [0001] The invention belongs to the field of equipment accessories, and in particular relates to a method and a device for detecting the state of a leather case of equipment. Background technique [0002] At present, smart phones have become a very important tool in people's daily life, bringing great convenience to people's life. [0003] In order to protect the mobile phone body and improve the intelligence of the mobile phone display, many mobile phones are provided with a leather case display function. That is, there is a transparent display window on the holster that can be in contact with the screen. When the mobile phone holster is closed, since a magnetic block is provided at a predetermined position of the mobile phone holster, the mobile phone is provided with a device that can receive A sensor for the magnetic signal of the magnetic block. When it is detected that the mobile phone holster is closed, the screen is lit at the corresponding position...
