Description

[0001] PORTABLE ELECTRONICS WITH IMPACT PROTECTION FUNCTION WITH IMPACT PROTECTION [0002]

The present invention relates to a portable electronic device having an impact protection function.

In the 21st century, electronic devices are rapidly evolving into miniaturized and portable devices. For example, in the case of a computer, a desktop is commonly used, but now it is changing to a portable electronic device that is gradually smaller, lighter, and aesthetic depending on the development of technology such as a notebook, a smart phone, and a tablet PC.

However, the portable electronic device has a disadvantage in that it can not guarantee safety because it is exposed to various use environments as much as it can be used while moving. For example, if you drop a portable electronic device while you are walking down the street, you may fall on a hard floor without any safety and risk of damage. However, in the prior art, since a separate safety device is not installed in the process of manufacturing the portable electronic device, the user must install the additional safety case for the safety of the portable electronic device. However, this approach detracts from the design of the original portable electronic device and reduces the user's satisfaction due to the additional cost.

 Therefore, it is necessary to develop a portable electronic device that prevents destruction of the portable electronic device due to gravity, such as dropping, without impairing the design of the original portable electronic device.

In this regard, Korean Patent Laid-Open Publication No. 2002-0097386 (entitled: Data Protection Device and Data Protection Method for Portable Devices) detects the acceleration of a portable device due to an external force, The data that is being reproduced or recorded by the portable device is controlled so that the power supply to the portable device is cut off so that the damage of the data due to the drop of the portable device or the secondary impact following external force can be minimized, .

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a portable electronic device which senses movement of a portable electronic device by a sensor, Thereby converting the portable electronic device into a semi-gravity state.

According to another aspect of the present invention, there is provided a portable electronic device having an impact protection function, the portable electronic device including: an acceleration sensor for detecting an acceleration of the portable electronic device according to movement of the portable electronic device; A control unit for controlling the operation of the power supply unit according to an acceleration value sensed by the acceleration sensor, a control unit for receiving a user's setting input for activating the shock protection function, A user interface unit for transmitting a control signal indicating whether or not the shock protection function is to be performed, information on a user's setting input through the user interface unit, information on the operation state of the acceleration sensor, To store one or more of Comprising a storage unit, the controller is included when it detects a rising or falling state of the portable electronic device on the basis of the acceleration values to the movable parts of the power supply to supply power to the coil.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings, in which: FIG. 1 is a perspective view of a portable electronic device according to an embodiment of the present invention;

1 is a conceptual view for explaining an operation effect of a portable electronic device having an impact protection function according to an embodiment of the present invention.

When a portable electronic device (hereinafter referred to as a portable electronic device) having an impact protection function deviating from the user's hand moves, the impact protection function of the portable electronic device is activated to form a semi-gravitational field. The anti-gravity field formed can reduce or even levitate the speed of a portable electronic device falling against the force of gravity pulled by the earth.

2 is a block diagram of a portable electronic device according to an embodiment of the present invention.

At this time, in the embodiment of the present invention, it is assumed that the portable electronic device 100 is a portable communication device (for example, a smart phone).

1, the portable electronic device 100 according to an exemplary embodiment of the present invention is shown in FIG. 1. However, the portable electronic device 100 may further include other processing units (not shown) depending on the type of the apparatus.

The portable electronic device 100 according to an embodiment of the present invention includes an acceleration sensor 110, a grip sensor 111, a coil part 120, a power supply part 130, a control part 140, an overcurrent prevention part 150, A user interface unit 160, and a log storage unit 170.

The acceleration sensor 110 can sense the acceleration of the portable electronic device 100 according to the movement of the portable electronic device 100. At this time, the acceleration sensor 110 can receive an acceleration value capable of grasping the falling, rising, and stopping states.

In addition, the portable electronic device 100 may include a grip sensor 111 for sensing whether the user grips the portable electronic device 100. The grip sensor 111 can sense whether the portable electronic device 100 is safely gripped by the user and information on the operation state of the grip sensor 111 can be additionally stored in the log storage unit 170 . For example, it can be detected through a change in capacitance caused by a touch of a user's hand or a pressure applied by a user's hand, and depending on whether the grip sensor 111 is sensed, Formation may or may not be performed. At this time, information on the operation state of the grip sensor 111 may be stored in the log storage unit 170, and a detailed description thereof will be described in detail in the description of the log storage unit 170. [

The coil part 120 is made of a coil and can be coupled to the inside of the portable electronic device 100. Also, the coil unit 120 may be connected to the power supply unit 130 to receive power.

The power supply unit 130 may apply power to the coil unit 120 under the control of the controller 140.

The control unit 140 controls the operation of the power supply unit 130 according to the acceleration value sensed by the acceleration sensor 110. That is, when the portable electronic device 100 senses the falling or rising state of the portable electronic device 100 based on the acceleration value sensed by the acceleration sensor 110, the control unit 140 activates the power supply unit 130, Power can be supplied.

At this time, the control unit 140 controls the power supply unit 130 to operate, and alternately supplies power to the first coil and the second coil. That is, by alternately supplying power to the first coil and the second coil, the respective coils can alternately form the anti-gravity field.

When the portable electronic device 100 is recognized as being gripped by the user through the grip sensor 111 in a state where the power supply unit 130 is operated, the control unit 140 stops the operation of the power supply unit 130 . For example, after the semi-gravity field is formed on the portable electronic device 100 determined to be dropped, when the portable electronic device 100 is gripped by the user and the grip sensor 111 is recognized, the controller 140 determines that the portable electronic device 100 is in a safe state So that the power supply of the power supply unit 130 can be stopped.

The overcurrent prevention unit 150 can prevent a current from flowing to the internal circuit board. For example, a circuit can be constructed based on a commonly known overcurrent prevention technique, and a detailed description of the circuit is omitted.

The user interface unit 160 receives a setting input of the user as to whether or not the impact protection function is activated and transmits a control signal to the control unit 140 regarding whether to perform the impact protection function.

For example, when the user deactivates the shock protection function through the user interface unit 160, the user interface unit 160 controls the power supply unit 130 even if the controller 140 receives the acceleration value from the acceleration sensor 110. [ Lt; RTI ID = 0.0 > a < / RTI > When the user activates the shock protection function through the user interface unit 160, the user interface unit 160 determines whether the acceleration sensor 110 senses the acceleration value and the grip sensor 111 It is possible to transmit a control signal for controlling the power supply unit 130 in response.

The log storage unit 170 stores at least one of information on the user's setting input through the user interface unit 160, information on the operation state of the acceleration sensor 110, and information on the operation state of the control unit 140, Information can be stored and matched. At this time, the log records the situation in which the shock protection function is activated over time and can be used to identify the cause of the accident when the accident occurs. That is, the shock protection function can be used as an identification data for determining whether an impact has occurred in a state in which the impact protection function is inactivated due to the user's will whether the shock has occurred in a normal operation state.

In addition, the log storage unit 170 may store the log encrypted in accordance with a predetermined time interval or a sensor operation condition. That is, the log can be automatically stored according to a periodic time interval or according to the acceleration value of the acceleration sensor 110 and the detection of the grip sensor 111.

For example, the log information may be periodically stored at an interval of 30 seconds, or the log may be stored when the grip sensor 111 and the acceleration sensor 110 are operated. Regardless of whether the sensor is operating during normal life, the log can be stored in a periodic time, or the log can be stored according to the time information from the start of operation when the grip sensor 111 and the acceleration sensor 110 are operated.

As another example, when the acceleration sensor 110 is operated while the grip sensor 111 of the portable electronic device 100 is not sensed and the acceleration value is decreased, it can be stored. That is, the log can be stored before the collision or when the grip sensor 111 is detected while the portable electronic device 100 is lifted up.

As another example, when the acceleration sensor 110 is operated while the grip sensor 111 of the portable electronic device 100 is not detected and the acceleration value is increased, it can be stored. That is, the log may be stored before the collision or when the grip sensor 111 is detected while the portable electronic device 100 is falling down.

As another example, logs can be saved when shock protection is disabled or activated. That is, a log immediately before and immediately after the impact protection function is deactivated by the battery discharge of the portable electronic device 100 or immediately before the power is turned off, immediately after the power is turned on, or the user interface 160) .

3 is a view showing a coil part of a portable electronic device according to an embodiment of the present invention.

As shown in FIG. 3, the coil part 120 in the portable electronic device 100 may include coils 121 and 122. For example, when the first coil 121 and the second coil 122 are coupled to the portable electronic device 100, the first coil 121 and the second coil 122 are respectively connected to the first power source 121 and the second coil 122, Power can be alternately supplied from a power source, and a semi-gravitational field can be formed by a coil supplied with power. At this time, the first coil 121 or the second coil 122 is formed in a triangle shape with three or more pillars 123 wound around the coil as a starting point, and the pillars are connected by a coil.

4 is a flowchart illustrating an operation flow of a portable electronic device according to an embodiment of the present invention.

In step S410, it is determined whether the gripping state of the portable electronic device is detected through the grip sensor. That is, if the grip sensor is sensed, it is determined that the portable electronic device is safely gripped by the user, and the movement of the portable electronic device is sensed if the grip sensor is not detected.

In step S420, the acceleration sensor can detect a change in acceleration due to the movement of the portable electronic device. That is, the acceleration value of the portable electronic device, which changes according to the drop or rise of the portable electronic device, can be detected through the acceleration sensor.

In step S430, if the portable electronic device that has left the user's hand moves based on the acceleration value input in the step, power is supplied to the coil. For example, when the user drops the portable electronic device due to the wobble of the table while the portable electronic device is placed on the table, the power can be supplied to the coil when it is determined that the portable electronic device falls based on the acceleration value. As a result, the portable electronic device can form a semi-gravitational field and lift the portable electronic device in the air.

In step S440, it can be determined whether the grip sensor of the portable electronic device having the semi-gravitational field is detected in the step. For example, if a user holds a portable electronic device suspended in the air, the power supply may be interrupted. If the user does not hold a portable electronic device in the air, the power supply can be continued.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
