Detailed Description
As described in the background art, the technical problem that the sensor cannot accurately detect the telescopic length of the telescopic screen along with the use time exists in the prior art. The inventors have found that the reason for this problem is as follows: the sliding terminal detects the telescopic length of the telescopic screen by using the sensor, the detection range is from the telescopic screen to extend out of the shell completely, the sensor can have accumulated errors along with the lengthening of the service time, the longer the service time is, the larger the errors are, especially, the corresponding detection value of the telescopic screen can not correspond to the correct detection value when the telescopic screen is completely contracted or completely stretched, and the deviation of the whole position detection value is caused because the judgment mode of the sensor is based on the continuous change of absolute values, so that the detection value of the sensor is inaccurate.
In order to solve the above problem, the inventors have studied and found that, since the determination mode of the detection means is continuously changed based on the absolute value, the calibration in the entire detection range can be realized by a linear relationship by calibrating at least two points in the entire detection range, particularly, the initial point and the end point. The opening that the flexible screen was received back or was stretched out the casing removes to preset position as the flexible screen, it can send the signal for core processing module to detect proofreading mechanism, core processing module proofreads the detection value that detection mechanism detected according to received signal, because detection mechanism's judgement mode is based on absolute value continuous variation, consequently, through the proofreading to the detection value that preset the position corresponds, can realize the proofreading to the whole skew of the flexible displacement detection value of flexible screen, the problem of the unable accurate flexible length that detects the flexible screen of current sensor has been solved.

Therefore, the preset position is set to be the initial position and the end position, and the calibration of the displacement detection of the telescopic screen 3 can be quickly and simply realized.
It should be understood that the first value may be set to a value of 0 and the second value may be set to a value equal to the width between the first end 101 and the second end 102 of the telescopic screen 3.

As shown in fig. 3, further includes: sliding grooves 21 at both ends of the housing 1; and a support frame 22 sliding inside the slide groove 21 for supporting the sliding of the retractable screen 3 along the slide groove 21; the connecting line of the initial position and the end position is parallel to the chute 21; the detection and collation mechanism 5 further includes: two hall sensors 52 provided at the initial position and the end position; the magnet 51 is positioned at the preset mounting position of the slide rail, and the magnet 51 is positioned at the intersection position of the support frame 22 and the second end 102 of the telescopic screen 3; the hall sensor 52 outputs a magnetically induced voltage through the induction magnet 51.
In the embodiment of the present invention, the magnet 51 is mounted on the support frame 22, and the two hall sensors 52 are disposed at the initial position and the end position, so that in the process that the support frame 22 drives the retractable screen 3 to extend and retract inside and outside the housing 1 along the chute 21, the magnet 51 and the retractable screen 3 are simultaneously driven to synchronously slide, when the magnet 51 passes through the hall sensors 52, a signal indicating that the retractable screen 3 reaches the preset position is transmitted to the core processing module 6 by using a magnetoelectric effect of the hall sensors 52, and the core processing module 6 performs calibration on a detection value corresponding to a detection origin based on the signal.

In the embodiment of the present invention, in the moving process of the magnet 51, when the magnet 51 approaches the hall sensor 52, a magnetic induction voltage is generated by the hall sensor 52, which causes a phenomenon that the core processing module 6 receives a signal when the retractable screen 3 does not reach a preset position, and thus, the calibration of the reference point of the detection mechanism 4 is not accurate, and the whole calibration process is not accurate, therefore, the filtering module 53 is arranged between the hall sensor 52 and the core processing module 6, when the voltage value of the magnetic induction voltage output by the hall sensor 52 reaches the preset voltage value, that is, when the magnet 51 is aligned with the hall sensor 52 (indicating that the retractable screen 3 reaches the preset position), the core processing module 6 receives the signal, so that the calibration reference point of the detection mechanism 4 is more accurate, and the whole calibration process is accurate.

In the embodiment of the present invention, the magnetic induction voltage emitted by the hall sensor 52 changes with the distance between the magnet 51 and the hall sensor 52, the smaller the distance between the magnet 51 and the hall sensor 52 is, the larger the magnetic induction voltage emitted by the hall sensor 52 is, and when the magnet 51 and the hall sensor 52 are in direct correspondence, the largest magnetic induction voltage emitted by the hall sensor 52 is. The reference voltage is controlled by adjusting the resistor 532, so that the value of the reference voltage is equal to the voltage corresponding to the magnet 51 and the hall sensor 52, and when the voltage value of the magnetic induction voltage output by the hall sensor 52 reaches a preset voltage value, a voltage signal is sent to the electric-digital conversion module 54. The electrical-to-digital conversion module 54 converts the voltage signal into a digital signal (e.g., binary value of 0, 1) that can be recognized by a computer. Specifically, the first end of the comparator 531 receives the magnetic induction voltage sent by the hall sensor 52, the second end of the comparator 531 receives the reference voltage, when the magnetic induction voltage sent by the hall sensor 52 is greater than or equal to the reference voltage, the third end of the comparator 531 outputs a voltage signal to the electrical-to-digital conversion module 54, the core processing module 6 can receive a digital signal indicating that the second end 102 of the retractable screen 3 reaches the preset position, when the magnetic induction voltage sent by the hall sensor 52 is less than the reference voltage, the third end of the comparator 531 does not send a voltage signal to the electrical-to-digital conversion module 54, the core processing module 6 cannot receive the signal, the core processing module 6 can only receive the signal when the magnetic induction voltage sent by the hall sensor 52 reaches the preset voltage (that is, the retractable screen 3 reaches the preset position), the time for receiving the signal is accurate, the reference point for calibrating the detection value of the detection mechanism 4 by the core processing module 6 is also accurate, and the whole calibration process is accurate.
