FIG. 1 is a side view showing a black box shooting device for a vehicle according to an embodiment of the present invention installed in a vehicle, FIG. 2 is a front view of the black box shooting device for a vehicle of FIG. 1, FIG. 4 is a view for explaining the operation of the vehicle black box shooting interrupter of FIG. 1; FIG.

1 to 4, a black box shooting device for a vehicle 10 according to an embodiment of the present invention can be fixed to a point of a vehicle or a black box B for a vehicle by a cradle 20, And selectively blocks the vehicle black box B from shooting the outside of the vehicle. Thereby, when the vehicle enters the security facility, the inside of the security facility can be prevented from being photographed by the black box (B).

In the present embodiment, the vehicle black box B means a device capable of recording the external situation of the vehicle by having a predetermined photographing means C, and for the sake of convenience of explanation, hereinafter referred to as "black box" . In addition, although the installation position of the black box B is shown as an example in the present embodiment, it is provided on the windshield G, but the spirit of the present invention is not limited thereto. For example, the black box may be installed in a room mirror, or may be installed in a rear window of a vehicle to photograph the rear of the vehicle.

The cradle 20 is provided so that the blocking device 10 can maintain a state in which the blocking device 10 is adjacent to the black box B or directly coupled with the black box B. In this embodiment, 220, and is fixed to the front glass G in an adsorption manner. Further, in this embodiment, the cradle 20 is provided as an example in which the shielding device 10 is provided so as to be disposed at a predetermined distance from the black box B. However, the features of the cradle 20 are merely examples, and may be implemented differently according to the embodiment. For example, the cradle 20 may be fixedly attached to the front glass G, may be fixed to a room mirror, a ceiling or the like of the vehicle, or may be fixed to the black box B .

The holder 20 may be adjustable in length or adjustable in angle to adjust the relative positions of the shielding device 10 and the black box B. [ For example, the holder 20 may include an extension 210 extending a predetermined length from the suction unit 220 and capable of bending, a universal joint 210 provided at one point of the extension 210 to bend the extension 210, (230).

The extension 210 may also include a length adjustable means, such as a screw connection, a telescopic device, a bellows, etc., to position the blocking device 10 to correspond to the size and position of the black box B.

On the other hand, the shielding device 10 can be detachably coupled to the cradle 20. For example, the cradle 20 and the interrupter 10 can be hook-engaged. That is, when the shutoff device 10 needs to be replaced in the vehicle due to a failure or the like of the shutoff device 10, the shutoff device 10 can be removed from the mount 10 to replace only the shutoff device 10.

The blocking device 10 is a device for preventing the outside of the vehicle from being photographed by the black box B and includes a main body 110 and a main body 110 for blocking A driving unit 130 provided in the main body 110 and driving the blocking unit 120, a power supply unit 140 supplying power to the driving unit 130, A communication unit 150 that can control the above components, and a control unit 190 that can control the above components.

The main body 110 can be connected to a mount 20 fixed to the glass G of the vehicle. At this time, the position and angle of the main body 110 can be adjusted through the cradle 20, so that the blocking means 120 can be provided at a position to block the photographing of the black box B.

The main body 110 may be formed in various shapes. For example, the main body 110 may be composed of an upper portion on which a PCB or the like can be mounted, and a lower portion on which the cut-off means 120 is disposed. At this time, the upper portion and the lower portion may be a part of the housing formed integrally with each other and may have a predetermined angle with respect to the side view.

The blocking means 120 can be provided at a position where the blocking means 120 is housed inside the main body 110 and blocks the photographing means C of the black box B by blocking the photographing of the black box B. [ For example, a through hole may be formed at a position corresponding to the black box B in the lower portion of the main body 110, and the blocking means 120 may be installed in the through hole of the main body 110.

At this time, the blocking means 120 may include a transparent film, which is turned on or off depending on whether a current is supplied or turned on or off. For example, the blocking means 120 may be a PDLC film (Polymer Dispersed Liquid Crystal Film) or a transparent electrode with an LED. In this embodiment, a description will be given by taking as an example the case where the PDLC film is provided as the blocking means 120.

Specifically, the blocking means 120 may be a PDLC film itself, or may be provided in a form in which the PDLC film is attached to the glass, and the PDLC film is disposed so as to block the photographing range of the photographing means (C).

The PDLC film is a film in which a polymer liquid crystal is dispersed between two ITO films. The PDLC film is a film capable of changing the arrangement of liquid crystal molecules depending on whether the power source is connected or not, thereby controlling transparency and opacity. For example, it can remain opaque without power on, and can be transparent when powered on. Conversely, it is possible to maintain the transparent state when the power is not turned on, and to switch to the opaque state when the power is turned on.

Specifically, the blocking means 120 controls the first state (FIG. 4A) in which the black box B is not blocked and the second state in which the black box B is blocked (b). That is, the blocking means 120 maintains the transparent state before the blocking device 10 receives the blocking signal (the first state), so that the blocking of the black box B is not blocked. Then, when the blocking device 10 receives the blocking signal (the second state), the blocking device 120 is switched to the opaque state, and the blocking device 120 blocks the photographing of the black box B. [ That is, the blocking unit 120 operates in a transparent or opaque manner depending on the blocking signal, thereby blocking or maintaining the photographing of the black box B.

At this time, the blocking means 120 may have a first state when an electric current is supplied, and a second state when no electric current is supplied. For example, if the administrator of the security facility gives the black box (B) photographing blocking signal to the blocking device 10, the control unit 190 can block the current supplied to the blocking unit 120, Can thereby be switched from the first state to the second state. In addition, even if the owner of the vehicle turns off the vehicle after the shutoff means 120 enters the second state, since the current supply to the shutoff means 120 is blocked, the shutoff means 120 is in the second state .

Thereafter, when a black box (B) unblocking signal is transmitted from the administrator of the security facility to the blocking device 10, the control unit 190 resumes the current supply to the blocking unit 120 to make the blocking unit 120 transparent .

Conversely, the blocking means 120 may have a first state when no current is supplied, and may be set to have a second state when current is supplied. For example, if the administrator of the security facility gives the black box (B) photographing blocking signal to the blocking device 10, the control unit 190 can supply current to the blocking means 120, The second state can be switched from the first state to the second state.

Although the blocking means 120 is provided as a PDLC film and the PDLC film is switched to a transparent / opaque state to block the photographing of the black box B in the present embodiment, It does not. For example, the blocking means 120 may be provided as a transparent electrode to emit opaque light, or to block the photographing of the black box B by white phenomenon. Further, the blocking means 120 is provided as a transparent glass, and a light emitting LED is provided around the transparent glass, so that the white phenomenon occurs due to the light emission of the LED, so that the photographing of the black box B can be blocked. In this case, there is an effect that the operation of the shielding device 10 can be confirmed from the outside by the light emission or not.

Meanwhile, the blocking device 10 may be driven through the driving unit 130. The driving unit 130 may include a driver and a switch for supplying current to the blocking unit 120 according to a control signal of the controller 190. Specifically, the driving unit 130 can selectively transmit the current received through the power supply unit 140 to the blocking unit 120, thereby adjusting the arrangement of the liquid crystal molecules of the PDLC film as the blocking unit 120, State, and the second state can be switched.

 The power supply unit 140 for supplying current to the driving unit 130 may be connected to the vehicle. At this time, the power supply unit 140 may be connected through a dedicated cigar jack of the vehicle, thereby enabling continuous current supply from the vehicle. However, the power supply unit 140 is not limited thereto. For example, the power supply unit 140 may be a rechargeable battery by a power supply of the vehicle, or a replaceable battery.

On the other hand, the blocking device 10 can receive a blocking signal through the communication unit 150. The communication unit 150 may be a module capable of RF (Radio Frequency) and IR (Infrared Ray) communication. In this embodiment, the communication unit 150 is an infrared receiver. Here, communication means that predetermined data or signals can be received or transmitted. In another embodiment, the communication unit 150 may be a communication module using Bluetooth, WI-FI, Zigbee, RFID, NFC, or the like.

The communication unit 150 can receive the black box B photographed or blocked from the outside. Specifically, the communication unit 150 can receive a signal transmitted from a predetermined command device such as a remote controller owned by a manager of a security facility that needs to block the photographing of the black box (B). For example, the IR receiver 151 may be provided on one side of the main body 110 to receive a blocking command or a blocking release command transmitted from the command device in the form of an infrared signal.

In another embodiment, the communication unit 150 may further include transmitting means for transmitting the identification information of the vehicle to the outside. The information transmitted by the intercepting device 10 through the communication unit 150 may be information such as the type of vehicle, the vehicle number, the security level, the information of the vehicle owner, and the identification code of the intercepting device 10. In this case, the administrator of the security facility can confirm the signal and information transmitted from the communication unit 150, and then transmit the blocking command of the black box B to the blocking apparatus 10 side through the command apparatus.

On the other hand, the blocking device 10 may include a sensor 160 for preventing a user from accidentally shooting the inside of the security facility for an unintentional purpose by adjusting the position of the blocking device 10 or the black box B . The sensor 160 may be provided to the main body 110 or the blocking means 120 by sensing the relative positions of the blocking means 120 and the black box B. [ In this embodiment, the sensor 160 is provided on one side of the main body 110 surrounding the shielding means 120. As shown in FIG.

For example, the sensor 160 may be a distance measuring sensor that measures the distance between the blocking means 120 and the black box B, and at least when the blocking means 120 is in the second state, The distance between the boxes B can be measured and transmitted to the controller 190.

The distance measured through the sensor 160 is transmitted to the controller 190. The controller 190 can compare the set value stored in the memory 180 with the value received from the sensor 160. [ In this case, when the value detected by the sensor 160 is different from a predetermined setting value, for example, when the value is greater than the predetermined setting value, the controller 190 may move the position of the cutoff device 120 or the cutoff device 10 Information on the information can be stored in the memory 180 or can be displayed externally through the output unit 170.

Specifically, relative positional information of the blocking device 10 and the black box B at the time of vehicle installation of the blocking device 10 can be measured by the sensor 160 and stored in the memory 180, Measures the relative positions of the blocking device 10 and the black box B at real time or at predetermined time intervals after the blocking means 120 is switched to the second state. The control unit 190 determines whether the value transmitted from the sensor 160 is within a preset range based on the initially measured value when the blocking unit 120 is in the second state. The administrator of the security facility or an outside person can check the information stored in the black box B. [

At this time, the operation of the sensor 160, and the result recording and output switching thereof may be operated through a separate battery (not shown). Accordingly, the sensor 160 can be operated to shut off the black box (B) shooting even when the start of the vehicle is turned off or the power supply to the cut-off device 10 is cut off.

On the other hand, the output unit 170 is provided for transmitting predetermined information to a vehicle occupant or a person outside the vehicle, and may transmit auditory information or time information. For example, the output unit 170 may include a first output unit 171 for transmitting information to the occupant of the vehicle and a second output unit 172 for transmitting information to the outside of the vehicle. In this embodiment, a first output unit 171 for transmitting information to a passenger is provided as a speaker for outputting auditory information, and a second output unit 172 for transmitting information to the outside is a display for outputting time information or And is provided as a light emitting means.

Specifically, the first output unit 171 can transmit the operating state of the shutting device 10 to the passenger. For example, when a shutoff command is received from the outside or a shutoff release command is received, Can be informed. When the change of the relative position of the blocking device 10 and the black box B is detected by the sensor 160, a warning message may be transmitted to the passenger. The first output unit 171 may be disposed on a side surface or a rear surface of the main body 110. In this embodiment, a speaker is provided on one side surface of the main body 110. [

Likewise, the second output unit 171 can display an instruction from the command device, an operation status of the screen device 10, and the like, and can display it by various methods such as characters, patterns, and colors. In particular, when the relative position between the blocking device 10 and the black box B is changed to a predetermined range or more, the control unit 190 controls the blocking device 10 and the black box B to the outside of the vehicle through the second output unit 171 By displaying the relative position change of the black box B, it is possible to achieve more secure security. For example, if the blocking device 10 is in the first state, there is no indication, but in the case of switching to the second state, the first color can be displayed. In addition, when the relative positions of the blocking device 10 and the black box B are changed, the second color is displayed so that the external manager can recognize the second color more easily. To this end, the second output unit 172 may be disposed on the front surface of the main body 110.

In another embodiment, the second output portion 172 may be a transparent electrode which is disposed in a superposition with the PDLC film as the blocking means 120 and can display a predetermined character or pattern.

Hereinafter, the operation and effect of the black box shooting and blocking device 10 for a vehicle according to an embodiment of the present invention will be described.

The black box B can be installed in the vehicle through the cradle 20 and the blocking device 10 can be selectively installed in the black box B in accordance with the signal transmitted by the manager of the security facility through the command device. (B) can be blocked.

For example, the blocking device 10 may be installed in a vehicle of a person with frequent access to security facilities, such as an employee of a security facility or an employee of a partner company. This eliminates the need for the administrator of the security facility to manually install a device capable of blocking the shooting of the black box B in the vehicle every time the vehicle comes in and out.

The administrator of the security facility, for example, the security guard, may be a person who works at the entrance gate of the security facility, and has a predetermined command device. The command device may be any device capable of providing a shutdown command or a shutdown release command to the shutdown device 10. If the communication device 150 provided in the shutdown device 10 is an infrared ray receiver as in the present embodiment, Lt; / RTI >

When the blocking device 10 is mounted on the vehicle approaching the entrance gate, the administrator of the security facility transmits the black box (B) photograph blocking command to the blocking device 10 by operating the command device. At this time, the blocking device 10 may output predetermined information for displaying the existence of the blocking device 10 to the administrator of the security facility through the output unit 170.

The blocking means 120 of the blocking device 10 may be in a first state, that is, a state of not blocking the photographing of the black box B, for example, a transparent state before receiving a blocking command. The control unit 190 of the blocking device 10 switches the blocking unit 120 from the first state to the second state by controlling the driving unit 130 upon receiving the blocking command through the communication unit 150, The photographing of the box B is interrupted. That is, the photographing of the black box B can be automatically interrupted even if the occupant manually manipulates the black box B or does not operate the blocking device 10.

At this time, the control unit 190 can transmit to the passenger or the manager through one or more of the first output unit 171 and the second output unit 172 whether or not the shutoff command has been received and whether the shutoff command has been switched to the second state. The administrator of the security facility can check whether the blocking device 10 has been normally operated through the information provided through the second output unit 172 and can take appropriate measures if the blocking device 10 is not operated normally.

In addition, the administrator of the security facility determines whether the blocking unit 120 is switched to transparent / opaque or whether the blocking of the black box B is normally performed through the light emitted when the blocking unit 120 emits light You may.

The sensor 160 can measure the relative position of the blocking device 10 and the black box B when the blocking means 120 switches to the second state in which the black box B is blocked. The measured value of the sensor 160 is transmitted to the controller 190. The controller 190 compares the set value stored in the memory 180 with the value received from the sensor 160, It is possible to judge whether or not it is within the range. When the blocking device 10 is out of the range, it is recognized that the black box B photographing has not been properly blocked, and the control unit 190 controls the blocking device 10 to the outside of the vehicle through the output unit 170, And the black box (B). Therefore, it is possible to prevent the user from accidentally moving the position of the blocking device 10 or the black box B to resume the black box B photographing.

In addition, the sensor 160 can operate through a separate battery (not shown). Accordingly, the sensor 160 can smoothly operate even when the starting of the vehicle is turned off or the power supply to the cut-off device 10 is cut off during the operation of the cut-off device 10 so that the black box B or the cut- It is possible to detect the movement of the position of the robot.

On the other hand, as another embodiment, the blocking device 10 may further include a GPS module (not shown). In this case, the control unit 190 can drive the driving unit 130 based on the positional information obtained from the GPS module (not shown), not the command transmitted through the communication unit 150. [ Specifically, the position range requiring photographing interruption may be preset and stored in the memory 180. If it is determined that the position information obtained from the GPS module (not shown) is within the preset range, the controller 190 controls the driving unit 130 So that the blocking means 120 can keep the black box B blocked. Of course, the blocking unit 120 may be driven in consideration of the position information obtained from the GPS module (not shown) together with the command transmitted through the communication unit 150. Accordingly, when the vehicle including the blocking device 10 enters the GPS (module) within a predetermined range, the blocking device 10 operates automatically to block the black box B photographing even if there is no blocking command from the security facility manager .

Hereinafter, a black box photographed device 10 'according to another embodiment of the present invention will be described with reference to FIGS. 5 to 7. FIG. However, the other embodiments are different from the embodiment in that the main body, the blocking means, the driving portion, and the like are different.
