The locking unit 200 receives signals from the MCU and the MCU, which analyzes the sub-motor 201, the receiving unit receiving the signal from the Bluetooth, the signals received from the reception, and gives out the control signal for controlling the sub-motor 201 to the FET switch. It may further include a sub-motor power control unit (not shown) to turn off the power of the sub-motor 201.

Specifically, the rotation of the sub-motor 201 to -90 degrees to +90 degrees is electronically controllable. In general, the sub motor 201 is controlled by maintaining the pulse duration (DURATION) HIGH for a specified time in a period of 20 msec. For example, a rotation angle of +90 degrees can be obtained at -90 degrees and 2.3 msec at 0.7 msec. That is, the submotor 201 can be controlled by outputting a value between 0.7 msec and 23 msec. The submotor 201 may use two types of submotors 201, digital and analog. Once the control signal is given, digital maintains the changed angle without changing the data until it is changed, while the analog keeps the changed angle when the signal is continuously given.

More specifically, when the signal received from the receiver is a signal in the right direction, the MCU reduces the pulse duration until the signal reaches 0.7 msec by the designated STEP (8.8usec / 1 degree) each time a signal is input. On the contrary, if the signal is on the left side, the pulse duration is increased until 2.3msec is reached by the designated STEP (8.8usec / 1 degree) for each signal. In order to reduce the power consumption of the battery, if the direction change signal does not come in for a certain time, the power connected to the FET switch in the sub-motor power control unit (not shown) is cut off.

Accordingly, the sub-motor 201 may receive the control signal and couple the male screw and the female screw 202 connected to the sub-motor 201 to lock the left body portion 101 and the right body portion 102.

In addition, in order to form a strong lock coupling, the required voltage of the sub-motor 201 may be high, in which case the battery unit (not shown) may further include a voltage amplifier circuit to amplify the voltage.

In the smart device 10, an application for controlling the locking or unlocking of the locking unit 200 is installed through the Bluetooth chip 300, and if the release of the locking unit 200 through the application fails, the smart device ( A warning sound is output through the speaker (not shown) of 10).

In order to control the lock unit 200 using an application, the user may set a predetermined ID and password to synchronize the smart device 10 and the smart device anti-theft case 100.

When the user installs the application on the smart device 10 and inputs the same value as the ID and password previously set on the application initial screen, a page for synchronizing the smart device anti-theft case 100 may be output.

At this time, the synchronization may use the Bluetooth pairing function, but is not limited thereto.

When the synchronization of the smart device anti-theft case 100 and the smart device 10 is completed, the user can set a predetermined lock password, and unlock the lock password every time the lock combination of the smart device anti-theft case 100 is released. You can enter it to release it.

In addition, as shown in FIG. 2, a lock button may be output on the application screen 11 to lock the smart device anti-theft case 100.

If the user continuously inputs a lock password different from the preset lock password three or five times, the application may output a warning sound through a speaker (not shown) of the smart device 10.

Through this, the user can indirectly know the location of the stolen smart device 10, there is an effect that can warn the third person, not the user.

In another embodiment, when the release of the lock unit 200 through the application fails, the application transmits the location information of the smart device 10 to a number previously stored in the application by using the communication module of the smart device 10. can do.

Specifically, when the smart device 10 is separated from the user by a predetermined distance or more, the user may not know the whereabouts of the smart device 10 only by a warning sound by a speaker (not shown) of the smart device 10. Therefore, when the third person continuously wrongly inputs the lock password at a remote place and the release of the lock unit 200 fails, the third person may transmit the location information of the smart device 10 to another number previously stored. .

The smart device 10 has a built-in GPS to determine the location of the smart device 10, it is possible to send coordinate values to other smart devices through the communication module of the smart device 10, the other smart device receives One coordinate value can be used to determine the location of the smart device 10 using a map application.
