This application claims priority under 35 U.S.C. §119(a) to a Korean Patent Application filed in the Korean Intellectual Property Office on Aug. 13, 2015, and assigned Serial No. 10-2015-0114543, the entire disclosure of which is incorporated herein by reference.
BACKGROUND
1. Field of the Disclosure
The present disclosure relates generally to an accessory mounted on a user terminal device, such as a smartphone, a tablet personal computer (PC), etc. and, more particularly, to a method for protecting a terminal from a shock and providing a basic accessory function.
2. Description of the Related Art
Existing mobile accessories have been used merely for pure accessory purposes, such as decoration, device protection, cradling, etc. For example, a flip-cover accessory has been used with various cover colors and designs, or with various transparent window positions.
There are some essential accessories which are often purchased when people buy smartphones. Such essential accessories include a cover case and a window protection film for protecting an expensive device. When a user drops a smartphone, breakage of the device may be alleviated with the cover case and the window protection film.
Thus, in a conventional electronic device (e.g., a smartphone), a protective cover may physically protect a display provided on a front surface of the electronic device when coupled to a rear surface of the electronic device.
However, when the electronic device receives a shock from being dropped with the cover open, a display region of the electronic device is not protected, causing damage to the display glass or liquid crystals. To protect the display region, the display region needs to be covered with a separate protection film or cover, degrading usability.

The present disclosure has been made to address at least the above-mentioned problems and/or disadvantages, and to provide at least the advantages described below.
Accordingly, an aspect of the present disclosure is to provide a function of controlling cover opening and closing to protect a display region of an electronic device using an accessory cover of the electronic device when the electronic device is dropped.
In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes a sensor module configured to detect a motion state of the electronic device when a cover is connected to the electronic device, and a processor configured to control an actuator of the cover based on the detected motion state of the electronic device.
In accordance with another aspect of the present disclosure, a protection device for protecting an electronic device is provided. The protection device includes a connection portion connected with the electronic device, an actuator configured to actuate the protection device, and a controller configured to control the actuator based on a control signal obtained from the connected electronic device through the connection portion.
In accordance with another aspect of the present disclosure, a method for protecting an electronic device is provided. The method includes detecting connection of a cover to the electronic device, detecting a motion state of the electronic device upon connection of the cover, and controlling an actuator of the connected cover based on the detected motion state.

FIG. 4 is a block diagram of configurations of an electronic device and a protection device, according to an embodiment of the present disclosure.
Referring to FIG. 4, an electronic device 400 and a protection (or cover) device 450 is provided. The electronic device 400 includes a sensor module 410, a display 420, an interface unit 430, a power management unit 440, a processor 460, and a memory 470.
The sensor module 410 includes one or more of a gyro sensor 411 and an acceleration sensor 412. The sensor module 410 detects a motion state of the electronic device 400. For example, the sensor module 410 may detect a speed change (an acceleration) and an orientation change of the electronic device 400.
The acceleration sensor 412 detects a change in a speed of the electronic device 400 at which the electronic device 400 moves along an x-axis, a y-axis, and a z-axis of an orthogonal coordinate system.
The gyro sensor 411 detects the amount of rotation of the electronic device 400 that rotates along the x-axis, the y-axis, and the z-axis of the orthogonal coordinate system.
The speed change or the amount of rotation of the electronic device 400 detected by the acceleration sensor 412 and the gyro sensor 411 may be transmitted to the processor 460. The processor 460 determines whether the electronic device 400 is dropped based on the motion state detected by the sensor module 410.
The sensor module 410 detects an orientation state of the display 420. For example, if the electronic device 400 is dropped, the sensor module 410 detects whether the orientation of the display 420 provided on a front surface of the electronic device 400 is the same as or opposite of a dropping direction. The processor 460 controls the protection device 450 based on the orientation of the display 420 detected by the sensor module 410 and the determination of whether the electronic device 400 is dropped.
The sensor module 410 detects an opening/closing state of the protection device 450 connected to the electronic device 400 through the interface unit 430. For example, the sensor module 410 may include one or more of a proximity sensor, an illumination sensor, and a magnetic sensor for detecting opening and closing of the protection device 450. For example, the illumination sensor may be disposed between the protection device 450 and the electronic device 400 to detect illumination between the protection device 450 and the electronic device 400. If the detected illumination is less than or equal to a preset illumination value, the processor 460 determines that the protection device 450 is closed. If the detected illumination is greater than the preset illumination value, the processor 460 determines that the protection device 450 is open. The proximity sensor may detect a proximate distance between the protection device 450 and the electronic device 400 and determine whether the protection device 450 is closed or open based on the detected proximate distance. The magnetic sensor may detect a strength of a magnetic force of a magnet included in the protection device 450, and the processor 460 compares the detected strength of the magnetic force with a preset magnetic force strength and determines based on a comparison result whether the protection device 450 is closed or open.
The display 420 displays a specific image corresponding to a control command of the processor 460. The display 420 is included on a surface of the electronic device 400.
The interface unit 430 determines whether the protection device 450 is connected to the electronic device 400.
The power management unit 440 supplies power to each module in the electronic device 400.
The processor 460 includes an AP 461 and a low power processor (LPP) 462.
The AP 461 controls input and output of the electronic device 400, and manages modules in the electronic device 400. Generally, any module in the electronic device 400 may be controlled by the AP 461, and power consumption corresponding to control by the AP 461 exceeds power consumption corresponding to an operation of the LPP 462. For example, if a use stop command with respect to the AP 461 is received from a user, an operation of the AP 461 may be stopped to minimize power consumption of the AP 461 and an operation of the LPP 462 set to control some sensor modules of the electronic device 400 may be initiated.
The memory 470 stores various programs necessary for an operation of the API 461 or logs detecting data necessary for opening and closing the protection device 450 for the LPP 462. The memory 470 loads or stores program-related system parameters for monitoring the dropping of the electronic device 400.
The protection device 450 includes a controller 451, a connection unit 452, an opening and closing unit 453, and an actuator unit 454. The connection unit 452 connects the electronic device 400 with the protection device 450.
The opening and closing unit 453 covers the front surface of the electronic device 400 when closed. For example, when the opening and closing unit 453 overlaps the front surface of the electronic device 400 in such a way to cover the front surface of the electronic device 400, the opening and closing unit 453 protects the display 410 provided on the front surface of the electronic device 400 from an external shock.
The controller 451 controls all modules in the protection device 450 based on a control signal sent from the electronic device 400. For example, upon receiving an opening and closing command with respect to the opening and closing unit 453 from the electronic device 400 through the connection unit 452, the controller 451 closes the opening and closing unit 453 such that the opening and closing unit 453 covers the display 410 of the electronic device 400. Upon receiving an opening and closing command with respect to the opening and closing unit 453, the controller 451 may close the opening and closing unit 453 by using the actuator 454 such that the opening and closing unit 453 covers the display 410 of the electronic device 400.
The actuator 454 may include a motor for closing the opening and closing unit 453 by applying a rotation force to the opening and closing unit 453; a magnet for closing the opening and closing unit 453 by using an electromagnetic force based on magnetism; and a shape memory material that is deformed by an electric force based on an external electric signal to close the opening and closing unit 453.

The connection unit 512 in the protection device 510 detects a state of connection with the electronic device 400 through the detection pin 513 and receives a control signal including the small amount of data being less than or equal to the preset amount, transmitted from the electronic device 400, through the ADC 514.
Referring FIG. 5B, a protection device 520 includes an opening and closing unit 521 and a connection unit 522. For example, to connect the protection device 510 to the electronic device 400, a connection unit 522 includes a detection pin 523 for detecting connection between the electronic device 400 and the protection device 510, and an NFC module 524 capable of receiving and transmitting a large amount of data greater than a preset amount from and to the electronic device 400. The connection unit 522 in the protection device 520 may detect a state of connection with the electronic device 400 through the detection pin 523 and receive a control signal including the large amount of data being greater than the preset amount, transmitted from the electronic device 400, through the NFC module 524. The connection units 512 and 522 may detect wireless connection through an NFC tag as well as wired connection through the detection pins 513 and 523.

The controller 451 may be included in a particular module of the protection device 610a. 
The electronic device 601 is connected with the protection device 610a through the connection unit 651.
Referring to FIG. 6B, a protection device 610b is connected to an electronic device 603. An opening and closing unit 655 of the protection device 610b covers a display 604 provided on a front surface of the electronic device 603, and an actuator 656 of a protection device 610b drives an opening and closing unit 655 of the protective device 629 to cover the display 604 depending on a control signal received from the electronic device 603.

Referring to FIG. 7, in step S701, the electronic device 603 detects connection of the protection device 610b to the electronic device 603.
In step S703, once the protection device 610b is connected, the electronic device 603 detects a motion state thereof. For example, the electronic device 603 may detect a motion state of the electronic device 603 through the sensor module 410 provided in the electronic device 603 and determine whether the electronic device 603 is dropped based on the detected motion state.
In step S704, the electronic device 603 controls the actuator 656 based on the detected motion state. The electronic device 603 controls the actuator 656 based on the motion state thereof to open and close the protection device 610b. The electronic device 603 controls the actuator 656 to open and close the opening and closing unit 655 of the protection device 610b. For example, if determining based on the motion state of the electronic device 603 that the electronic device 603 is being currently dropped, the electronic device 603 controls the actuator 656 to open and close the opening and closing unit 655 of the protection device 610b connected to the electronic device 603. For example, if determining that the electronic device 603 is currently dropped and the opening and closing unit 655 is open, then the electronic device 603 closes the opening and closing unit 655 by using the actuator 656 to protect a display 604.
FIG. 8A illustrates a method for protecting an electronic device, including a display, when the electronic device is dropped, according to an embodiment of the present disclosure.
Referring to FIG. 8A, an electronic device 801 is connected with a protection device 810a. The electronic device 801 obtains a motion state of the electronic device 801 detected by the sensor module 410, open and closed states of an opening and closing unit 851 of the prover device 810a connected to the electronic device 801, or an orientation state of a display 802 of the electronic device 801. The electronic device 801 determines based on the obtained motion state, open and closed states, and orientation state whether the electronic device 801 is dropped, whether the opening and closing unit 851 is open or closed, or the orientation of the display 802, and opens and closes the opening and closing unit 851 through an actuator 852 based on the determination.
If it is determined that the electronic device 801 is dropped when the opening and closing unit 851 is closed on the display 802 of the electronic device 801, the electronic device 801 sends an open and closed state maintaining signal for maintaining the closed state of the opening and closing unit 851 to the protection device 810a through a connection unit 853. Upon receiving the open and closed state maintaining signal through the connection unit 853, the protection device 810a controls the actuator 852 to maintain the closed state of the opening and closing unit 851.
Accordingly, the electronic device 801 may be connected with a protection cover 810a that includes the actuator 852 formed of a material reacting to an electric signal. The actuator 852 provides a function of opening and closing the opening and closing unit 851 flexibly and maintains the shape of the actuator 852 according to an electric signal generated from the electronic device 801 or the protective cover 810a upon the occurrence of a drop event.

If it is determined that the electronic device 400 is dropped in step S904, the electronic device 400 detects open and closed states of the opening and closing unit 453 of the protective device 450 in step S905.
In step S906, the electronic device 400 determines whether the opening and closing unit 453 is open.
If it is determined that the opening and closing unit 453 is open in step S906, the electronic device 400 closes the opening and closing unit 453 in step S907. For example, the electronic device 400 may open or close the opening and closing unit 453 through the actuator 454.
However, if it is determined that the opening and closing unit 453 is closed in step S908, the electronic device 400 controls the actuator 454 to maintain the closed state of the opening and closing unit 453 in step S908.
