Definitions of these terms should be based on the content of this specification.

1 is a schematic view showing a door unlocking device of the present invention.

The door unlocking apparatus shown in FIG. 1 includes a sensing unit 110 installed on a first surface 211 of a transparent door 210 and sensing a touch of a second surface 212 of the transparent door 210 can do.

At this time, the sensing result of the sensing unit 110 may be used for determining whether to lock or unlock the transparent door 210. [

At this time, the transparent door 210 refers to a door that can transmit light such as a glass door and an acrylic door. In the transparent door 210, the first surface 211 may be a surface facing the room and the second surface 212 may be a surface facing the outdoors. The transparent door can be installed in various buildings or vehicles.

In the case of the lock / unlock device of the keypad input method, the keypad is provided on the second surface 212 on which the user to open the door is located. That is, the keypad is installed facing the outdoors, and the touch by the user is directly performed. Such a keypad may be directly contacted, and the recognition rate of the keypad may gradually decrease. In addition, since it is directly exposed to various pollutants such as rainwater, dust, etc. applied in the external environment, the phenomenon of the keypad being damaged can be accelerated.

In order to prevent such a phenomenon, the sensing unit 110 constituting the door unlocking device of the present invention is provided on the first surface 211, that is, on the surface facing the interior of the building or the interior of the vehicle in the transparent door 210 . That is, the sensing unit 110 does not directly face outdoors. The sensing unit 110 may sense the touch of the user to the second surface 212 of the transparent door 210 in a state where the sensing unit 110 is installed on the first surface 211 of the transparent door 210.

For this, the sensing unit 110 may use light of various wavelengths passing through the transparent door 210. For example, the sensing unit 110 may sense a touch on the second surface 212 from the first surface 211 using an infrared ray or a laser.

The sensing unit 110 senses the touch of the second surface 212 and determines whether to allow the door to be opened by processing the sensed result. Alternatively, the sensing unit 110 may be provided separately from the sensing unit, The detection result can be transmitted to the control unit. In the former case, the control unit may be included in the sensing unit 110.

2 is a schematic view showing a sensing unit 110 constituting a door unlocking device of the present invention.

The sensing unit 110 shown in FIG. 2 includes an infrared / laser generating unit 111 that generates infrared rays or a laser and emits the generated infrared rays or laser rays in a direction from the first surface 211 to the second surface 212, And an infrared / laser sensor 113 that senses that the radiated infrared ray or laser is being returned by the touch of the second side 212 and senses the touch of the second side 212 with the detected infrared ray / laser have.

The infrared / laser generating unit 111 may emit infrared rays / laser in a direction perpendicular to the first surface 211 to improve the reliability of the infrared ray / laser as an element that generates and emits an infrared ray / laser. Of course, the infrared ray / laser is reflected in a tilted direction toward the infrared ray / laser sensor 113 in a direction orthogonal to the first surface 211 so that the infrared ray / laser reflected by the touch is projected to the infrared ray / .

The infrared ray / laser emitted from the infrared / laser generating unit 111 is absorbed, diffused, reflected, and the like when the user touches the finger or the like of the user who is touched with respect to the second surface 212. Among them, the reflected infrared / May be introduced into the infrared / laser sensor 113.

The infrared ray / laser sensor 113 outputs an electrical signal, a voltage, a current, and the like, which are different from those before the infrared ray / laser ray, when the infrared ray / laser is inputted. It is possible to detect that a touch has been made.

In order to open the door, a touch having a certain pattern may be required instead of a simple touch. It may be necessary to input a combination of characters 119 including numbers, special symbols, various languages, etc. in succession, or perform a touch to shape a specific shape.

If a combination of characters is required to be input, the sensing unit 110 may form a recognizable character on the surface when viewed from the direction of the second surface 212. At this time, the infrared / laser sensor 113, May be provided for each character.

Numerals 1, 2, 3, and 4 are displayed as characters in FIG. 2, and an infrared ray / laser sensor 113 is positioned at the center of each numeral when viewed from the second surface 212. The infrared / laser generator 111 may be disposed adjacent to the infrared / laser sensor 113 for reliable operation of the infrared / laser sensor 113. This state is shown in the numeral 1 and the numeral 2 in Fig. In this case, the same number of infrared / laser generating units 111 as the infrared / laser sensor 113 should be provided.

It is possible to reduce the number of infrared / laser generating units 111 installed for improving the productivity.

For example, when viewed from the direction of the second surface 212, the infrared / laser sensor 113 may be provided at a plurality of distances apart from the infrared / laser generating unit 111 by a predetermined distance. At this time, the infrared ray / laser emitted from the infrared ray / laser generation unit 111 is diffused from the second surface 212 where the touch is made to the infrared ray / laser sensor 113 when viewed from the direction of the second surface 212 . 2 and 3, the infrared / laser generating unit 111 is positioned in the middle between 3 and 4, and the infrared / laser sensor 113 is located at the center of each number. According to this, the number of infrared / laser generating units 111 can be reduced to nearly two times, and productivity is improved.

When the infrared ray / laser generated by the infrared ray / laser generation unit 111 has a linearity, the infrared ray / laser can be diffused in a desired range by adding a slit or the like for diffusing light in front of the infrared ray / laser generation unit 111 .

When the user touches the number 2 in the sensing unit 110 of FIG. 2, only the infrared / laser sensor 113 of the number 2 changes the output value, and the other infrared / laser sensor 113 should exhibit the same output value as the conventional one. At this time, when the progress distance of the infrared ray / laser generated by the infrared ray / laser generation unit 111 is not appropriate, the output value of the infrared ray / laser sensor 113 arranged at a number other than the number 2 may also show a change. For example, when the distance traveled by the infrared / laser is excessive, the infrared / laser generated by the infrared / laser generator of the numerals 3 and 4 when the number 2 is touched by the index finger of the right hand is reflected on other parts of the hand, 3 or 4 can also be recognized as being touched.

In order to prevent such a problem, when the distance between the first surface 211 and the second surface 212 of the transparent door 210 is defined as w, the infrared ray / laser generated by the infrared / 2w + a, where a is a positive value and an additional range. In an ideal situation, the traveling distance of the infrared / laser is 2w, but considering the loss of infrared / laser in the process of passing through the transparent door 210 and the amount of infrared / laser absorbed by the skin of the body corresponding to the reflector, Can be added, and a can be obtained by experiment.

The loss of the infrared ray / laser generated in the process of passing through the transparent door 210 may be caused by a metal component or the like contained in the transparent door 210. Since the transparent door 210 includes an appropriate metal component for shielding ultraviolet rays.

For reliable operation of the sensing unit 110, it is preferable that the infrared / laser sensor 113 does not react to the infrared ray / laser included in sunlight or the like. The infrared / laser generated by the infrared / laser generator 111 has a different wavelength from the infrared / laser included in the sunlight. The infrared / laser sensor 113 has infrared / Only the laser can detect.

According to this, the sensing unit 110 can be mounted on the transparent door 210 exposed to sunlight without any difficulty. In particular, it may be useful for a transparent door 210 installed in a vehicle.

In order for the sensing unit 110 to operate normally, the infrared / laser generator 111 must be driven. However, driving all the infrared / laser generating units 111 in a situation where the time for unlocking the door is very small compared to the time when the door is locked may cause power waste.

When viewed from the second surface 212, the sensing unit 110 may have a plurality of sensing areas 117 for sensing the touch of the second surface 212 formed at different positions. At this time, the first sensing area 117 of the plurality of sensing areas 117 may be maintained off. When the touch of the second surface 212 with respect to the second sensing area 117 is sensed, power can be supplied to the first sensing area 117. This can minimize power consumption. For the sake of convenience, as shown in FIG. 2, the area allocated to each character 119 may be displayed as a rectangle or the like to the user. At this time, the allocated area of each character 119 provided to the user may be similar to the sensing area 117 but not completely. It is preferable to match the allocation area recognized by the user with the sensing area 117 of the sensing unit 110 in order to improve the reliability of use. Hereinafter, it is assumed that the allocation area recognized by the user coincides with the sensing area 117 of the sensing unit 110. FIG.

The first sensing area 117 is a sensing area 117 that is not normally supplied with power and is kept in an off state and turned on by a specific signal. The specific signal at this time may be generated by the second sensing area 117. The second sensing area 117 is an area that is always kept on. The first sensing area 117 and the second sensing area 117 may be allocated to various sensing areas 117 according to a business policy. For example, in FIG. 2, 'Enter' may be the second sensing area 117. 'Enter' may be a function key for recognizing that the input is completed after inputting the number to the sensing unit 110.

Even if the initial 'Enter' is turned on and the other numeric keys are turned off, the sensing unit 110 does not react even if a touch is made to the numeric key. This is because the infrared / laser generating unit 111 and the infrared / laser sensor 113 corresponding to the numeric keys are turned off for the purpose of power saving. In this state, when 'Enter' corresponding to the second sensing area 117 is touched, power is supplied to the number keys corresponding to the first sensing area 117, and the infrared / laser generating unit 111 And the infrared / laser sensor 113 are in the ON state in which the touch can be detected. Accordingly, the user can input a desired combination of numbers by touching the " Enter " key and touching the " Enter "

On the other hand, if the touch of the numeric key is not performed while the infrared / laser generating unit 111 and the infrared / laser sensor 113 assigned to each numeric key are turned on with the 'Enter' touch, If it is maintained, the power saving efficiency can be reduced. For example, if a passing passenger accidentally touches " Enter " and then leaves his or her seat, the sensing unit 110 may detect a first key The detection area 117 can be returned to the OFF state again.

In other words, if the touch of the second surface 212 with respect to the first sensing area 117 turned on by the supply of power is not performed for the set time, 117 can be cut off.

There may be a case where the user unlocks the transparent door 210 through the normal use of the 'Enter' touch - the numeric key touch - 'Enter' touch. If the numeric key remains on after the lock is released, the power saving effect may be reduced. In order to prevent this, when the transparent door 210 is unlocked as a result of touching the second surface 212 with respect to the first sensing area 117, the sensing unit 110 supplies power to the first sensing area 117 It is possible to return to the initial state by blocking.

When a plurality of sensing areas 117 are provided, the productivity can be improved according to the overall shape after the placement of each sensing area 117 is completed. For example, an infrared / laser sensor 113 is provided for each sensing area 117, and an infrared / laser sensor 113 for providing an infrared / laser sensor to the infrared / laser sensor 113 provided for each sensing area 117. [ It is necessary to arrange the light emitting element 111. The number of infrared rays / laser sensors 113 should be the same as the number of detection areas 117, but the number of infrared rays / laser sensors 111 can be minimized according to the arrangement of the detection areas 117.

FIG. 3 is a schematic view showing a sensing area 117 of the door unlocking device of the present invention, and FIG. 4 is another schematic diagram showing a sensing area 117 of the door unlocking device of the present invention.

First, in FIG. 3, the entire shape of the sensing area 117 that has been laid out forms a circle.

According to this configuration, the arrangement of the infrared / laser generator 111 can be completed by disposing one infrared / laser generator 111 at the center of the circle. 3, the infrared / laser generating unit 111 is disposed at the center of the triangle to form an infrared / laser generating unit 111, Can be completed.

In addition, when the sensing area 117 is arranged in a shape such as a circle and a triangle, an effect of providing a beautiful appearance can be expected.

Meanwhile, the sensing unit 110 may be formed to have a small thickness. The infrared / laser sensor 113 and the infrared / laser generator 111 are included, and even if the controller is included in the infrared / laser sensor 113, it can be manufactured in a thin thickness. Therefore, the door unlocking device of the present invention including the sensing unit 110 may be attached to the transparent door 210 using an adhesive, a transparent adhesive tape, or the like without using a separate mechanical structure for attaching the door unlocking device of the present invention to the transparent door 210. [ As shown in Fig.

In the sensing unit 110, two types of signals may be output.

If the control unit is not included in the sensing unit 110, the sensing unit 110 may output the touch sensing result.

When the control unit is included in the sensing unit 110, the sensing unit 110 may output a result of comparing the touch sensing result with a predetermined touch pattern.

In either case, the output signal of the sensing unit 110 must be transmitted to the interrupter 230 which mechanically and substantially locks and unlocks the transparent door 210. If the control unit is not included in the sensing unit 110, the control unit will be included in the intermittent device 230. If the control unit is included in the sensing unit 110, Do.

5 is a schematic view showing a connection state of the door unlocking device and interrupter 230 according to the present invention.

The interrupter 230 may have a lock for mechanically locking or unlocking the transparent door 210, and a drive for driving the lock. At this time, a signal output from the sensing unit 110 may be used as a signal required to control the lock in the driving unit.

For this purpose, the interrupter 230 and the sensing unit 110 must communicate with each other. In this case, wired communication or wireless communication can be used for the communication.

When the wireless communication is used, the door unlocking device may include a wireless communication means capable of wireless communication with the interrupter 230 in addition to the sensing unit 110, and a battery for supplying power to each element. The installation of the wireless communication means and the battery may increase the volume and weight of the door unlocking device. The wire connecting the intermittent device 230 and the sensing unit 110 is unnecessary, so that a beautiful appearance can be provided and the installation is simple.

When wired communication is used, the door unlocking device must be electrically connected to the interrupter 230 through the wired wire portion 150. At this time, the wire unit 150 may have a connector in which one end is detached from the interrupter 230 and the other end is detached from the sensing unit 110. Accordingly, the wire unit 150 or the sensing unit 110 can be easily replaced. If the wire unit 150 is formed integrally with the sensing unit 110, both the wire unit 150 and the sensing unit 110 need to be replaced when the wire unit 150 or the sensing unit 110 is replaced. However, The lower surface detecting unit 110 or the wire unit 150 can be easily replaced.

When the wired wire part 150 is installed on the transparent door 210, it is possible to prevent the appearance of the wire door part 150. To prevent this, the wire part 150 is preferably a transparent film attached to and detached from the transparent door 210. When the wire part 150 is a transparent film, the wire part 150 can be easily attached to the transparent door 210 using a transparent tape or an adhesive, and can be easily detached from the transparent door 210 later.

When the wire unit 150 is used, the sensing unit 110 may be driven by power supplied through the wire unit 150. [ Therefore, the use of the wire unit 150 eliminates the need for a separate wireless communication means and a battery, thereby effectively reducing the thickness, size, and weight of the door unlocking device.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
