Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-2, a low power consumption mobile hard disk for stopping data transmission in a plug-in state includes a mobile hard disk main body, which includes a PCB board 1, a plug-in port 2 and a protective casing 3 assembled and matched with each other; a trigger 4 is movably arranged on the outer side of the protective shell 3, and an inductor 5 is fixedly arranged in the protective shell 3; the PCB board 1 is provided with an MCU and a power state control circuit 10, the voltage input end of the power state control circuit 10 is finally connected with an external input power supply, the control end of the power state control circuit 10 is connected with the inductor 5, and the output end of the power state control circuit 10 is connected with the input end of the MCU; wherein the trigger area of the sensor 5 is located within the active area of the trigger 4. The sensor 5 outputs a trigger signal for indicating the control of the conduction and a close signal for indicating the control of the power-off to the power state control circuit 10 by moving the flip-flop 4.
When the data transmission of the mobile hard disk and the data terminal is completed or the data transmission is stopped, the user can move the trigger 4 out of the trigger area of the sensor 5, the sensor 5 does not generate a trigger signal any more at this time, a closing signal is correspondingly generated, a power supply line between an external input power supply (provided by the plugged data terminal) of the power state control circuit 10 and the MCU is enabled, the power supply of the mobile hard disk can be stopped under the condition that the mobile hard disk is not unplugged, the mobile hard disk is prevented from being in a working state and a power consumption state for a long time under the plugging state, the service life of the mobile hard disk is effectively guaranteed, and the power consumption of the mobile hard disk is reduced.
When the mobile hard disk needs to be used continuously, the trigger 4 is directly moved into the trigger area of the inductor 5, the data terminal can read the mobile hard disk in the power-on state, and the effects of convenience in pulling-free, service life guarantee and power consumption reduction are achieved.
In the embodiment of the present invention, the trigger 4 is a magnet, and the sensor 5 is a hall sensor. The Hall sensor is non-contact induction to the response of magnet, and is corresponding, and protecting sheathing 3 need not to prepare the hole that is used for trigger 4 and inductor 5 contact, and protecting sheathing 3's waterproof performance can not be influenced because of setting up trigger 4, inductor 5.
Adopt the magnet as the trigger, it has and is used for the trigger effect outside, this portable hard drive also can adsorb fixedly through having magnetic trigger, if daily when accomodating, can adsorb this portable hard drive on the iron baffle of desk.
One of the moving modes of the trigger 4 is: a slide rail 6 is formed on the outer side of the protective shell 3, a slide block 7 slides on the slide rail 6, and the trigger 4 is arranged on the slide block 7; the slider 7 has a first sliding travel on the sliding track 6 that brings the trigger 4 into the triggering area of the sensor 5, and a second sliding travel that brings the trigger 4 into the non-triggering area 200 of the sensor 5 (outside the triggering area). By pushing the slider 7 to slide on the slide rail 6 in a fixed way, the trigger 4 can reach the trigger area 100 of the sensor 5 more accurately. Preferably, the slider 7 is a non-magnetic slider, so that the induced magnetic field is not uncontrollable due to magnetic conduction, and the accuracy is better.
Further, a first suction block 8 and a second suction block 9 are mounted on the outer side of the protective housing 3, the first suction block 8 corresponds to the trigger area 100 of the sensor 5, and the second suction block 9 corresponds to the non-trigger area 200 of the sensor 5; when the trigger 4 is located in the middle of the interval between the first suction block 8 and the second suction block 9, the suction force of the trigger 4 on the first suction block 8 and the suction force of the trigger on the second suction block 9 are mutually offset.

Referring to fig. 1 specifically, when the trigger 4 leaves the trigger area 100 of the sensor 5, the suction force of the second suction block 9 to the trigger 4 is greater than the suction force of the first suction block 8, so that the trigger 4 has a force moving leftward, and the force is greater the further the trigger moves leftward, the stroke limitation of the slide rail 6 to the slide block 7 may enable the first suction block 8 and the second suction block 9 to be out of contact with the trigger 4, or enable the first suction block 8 and the second suction block 9 to be out of contact with the trigger 4 by spacing the slide block 7 through non-magnetic conductivity. Through the design of the first suction block 8 and the second suction block 9, the trigger 4 is not easy to be touched by mistake and change position (the position change is realized by sliding of a sliding block), such as the situation that a data terminal is pushed on a desk, and a desk for bearing the data terminal is accidentally knocked on, and the like. The control stability is better.
When the trigger 4 is a magnet and the sensor 5 is a hall sensor, one of the design ways of the power state control circuit 10 can be as shown in fig. 2: the amplifier comprises an amplifier with the model of A741 and a triode Q1 with the model of 2N 5812. When the trigger is located in the trigger area of the inductor, the inductor 5 correspondingly outputs Hall voltage to the amplifier, the Hall voltage is amplified by the amplifier and then is transmitted to the base electrode of the triode Q1, the triode Q1 is in a conducting state, the input power supply correspondingly supplies power to the MCU through the conducted triode Q1, the trigger control is achieved, the overall design of the circuit is concise, and the practicability is good.
