1 to 4, an externally powered door lock system 100 according to an exemplary embodiment of the present invention includes a door lock 110, a power supply unit 120, and a power supply unit 130.

The door lock 110 is formed in the door 10 to control the door 10 in an open state or a closed state. In this case, the door lock 110 is a main key type for drawing in or drawing out the dead bolt 111 connected to the handle 112 of the door 10 and an auxiliary for introducing or withdrawing the dead bolt 111 separately from the handle 112. It can be implemented in a keyed fashion. The contact sensor 111-1 detects contact between the door 10 and the door frame 20. The door lock 110 receives external power through a power supply unit 120 and a power supply unit 130 to be described later to obtain driving power. The door lock 110 may have an internal power source 116 of a primary battery or a secondary battery therein. This is to supply power to move the dead bolt 111 of the door lock 110 in an emergency, and to drive without supply of external power in the event of power failure.

Specifically, the door lock 110 is formed by combining the first case 110-1 formed on the outdoor side of the door 10 and the second case 110-2 formed on the indoor side. In FIG. 2, (a) shows the first case 110-1 and (b) shows the second case 110-2. The display unit 113 is formed on the first case 110-1 to output a keypad, advertisement content, an identification code, and the like. A speaker 114 may be formed in the first case 110-1 to output sound. In addition, the sensing unit 140 may be added to the first case 110-1 to detect a user's approach using infrared rays or the like.

An LED 115 is formed in the second case 110-2 to display a remaining state or a failure state of the internal power source 116. In addition, an internal power source 116 in the form of a primary battery or a secondary battery may be formed in the second case 110-2. The internal power source 116 is detachably or inserted into the second case 110-2. The power supply unit 130 is formed in the second case 110-2. The cover 110-21 is formed in the second case 110-2 to close the internal power source 116 and the power supply / receiving unit 130. An optical signal receiver 117 may be formed in the second case 110-2. The optical signal receiver 117 may receive power from an external optical signal or receive a control signal.

In the above description, the structure of the first casing 110-1 and the structure of the second casing 110-2 are divided and described, but the present invention is not necessarily limited thereto, and the first and second casings 110-1 and the second casing 110-are described. The configuration between 2) may be formed to overlap each other.

The power supply unit 120 is formed at one side of the door frame 20 to supply external power through the first connection terminal 121. The power supply unit 120 is connected to an external power cable 30 to receive power. The first connection terminal 121 is formed of a metallic material or elastic spring having an elastic force such as a metal pin to supply power when connected to the second connection terminal 131 of the power supply 130. The power supply unit 120 may be formed integrally with the bracket formed on the door frame 20. The power supply unit 120 supplies power when the door 10 is connected to the power supply unit 130 in the closed state, and cuts off the power when the door 10 is spaced apart from the power supply unit 130 in the open state. The power supply unit 120 may also charge the internal power source 116 of the door lock 110.

As shown in FIG. 3, a plurality of first long holes 122 may be formed in the power supply unit 120. This is to prevent the contact due to the height difference between the power supply and supply unit 130 when the power supply unit 120 is fixed to the door frame 20. It is easy to adjust the height of the power supply and supply unit 130 by adjusting the height by inserting a coupling means such as a screw in the plurality of first long holes (122).

The power supply and supply unit 130 is connected to the door lock 110 and when the door 10 is in the closed state, the second connection terminal 131 is connected to the first connection terminal 121 to supply power to the door lock 110. do. In this case, the power supply unit 130 may be integrally formed with the door lock 110. For example, when the power supply unit 130 is integrally formed with the door lock 110, the power supply unit 130 is formed in a 'T' shape lying down, and a second connection terminal 131 is formed at a front end thereof to form a first connection of the power supply unit 120. The connection is overlapped with the connection terminal 121. At least one second long hole 132 is formed in the body of the power supply unit 130 in the longitudinal direction. This is to set the length exposed to one end of the door 10 to be variable.

In other words, the position of the perforated 11 to install the door lock 110 on the door 10 and the distance from the side of the door 10 may be different, so as to actively change it. Therefore, it is possible to increase the convenience of installation by adjusting the fixing position of the second long hole 132 in accordance with the gap between the position of the perforated 11 of the door 10 and the side surface of the door 10. In addition, by installing the power supply and supply unit 130 through the door lock 110 without puncturing the door to be installed, it is easy to install and minimize damage to the door.

As shown in FIG. 4A, when the door lock 110 is replaced according to the position of the perforation 11 in the door 10, the power supply 130 is not exposed to the side end of the door 10. The case occurs. In this case, when the first distance d1 between the cross-section of the power supply 130 and the side cross-section of the door 10 exceeds a preset value, the power supply 120 when the door 10 is in the closed state. ) Will not be connected. Accordingly, power is not supplied to the door lock 110. In order to improve this problem, as shown in Figure 4 (b) it is possible to move the power supply unit 130 in the horizontal direction by the end surface of the power supply unit 130 and the side cross-section of the door 10 When the first distance d2 between the portions is reduced than the first distance d1, and the door 10 is in the closed state within the preset value, the first distance d2 is connected to the power supply unit 120. This is because the length can be adjusted using the second long hole 132 formed in the power supply and supply unit 130 as shown in FIG.

5 is an exemplary view for explaining that the power supply unit separated from the door lock of the external power supply type door lock system according to FIG. 1 is connected to the power supply unit, and FIG. 6 is a detailed configuration diagram of the power supply unit and the power supply unit according to FIG. 4. to be.

1, 5 and 6, the power supply and supply unit 130 may be formed to be separated from the door lock 110. In the case of the double door 10, the power supply and supply unit 130 and the door lock 110 are preferably formed in a separate type. This is because in the case of the double door 10, the installation position of the door lock 110 and the position of the power supply unit 120 do not face each other. The power supply unit 120 may be formed as an upper surface of the door 10 of the door frame 20. In this case, since the two-door door 10 is movable, it is preferable to form the power supply unit 120 on the upper surface of the door frame 20. The power cable 30 of the power supply unit 120 may be arranged inside or outside the door frame 20.

In addition, the power supply unit 120 may supply power while shock absorbing. In detail, the power supply unit 120 may include a first body 120-1 having a bent structure, a first connection terminal 121 formed on a bottom surface of the first body 120-1, and The first power substrate 121-3 may be formed in the first body 120-1. For example, the first body 120-1 may be formed in a 'b' shaped structure. At least one first long hole 122 is formed on a vertical surface of the first body 120-1. The first long hole 122 is to change the installation height of the power supply unit 120 on the door frame 20. A coupling means such as a screw or a bolt is inserted into the first long hole 122 to fix the first body 120-1 to the door frame 20.

The first connection terminal 121 is formed such that one side is exposed to the bottom surface of the first body 120-1 as a bearing structure. In this case, the central shaft 121-1 of the first connection terminal 121 is connected to the first power substrate 121-3 through springs 121-2 at both ends thereof. The first connection terminal 121 may absorb a shock due to the difference in height when the second connection terminal 131 is connected to the second connection terminal 131. In addition, the first connection terminal 121 may improve durability by minimizing friction when connected to the second connection terminal 131 in a bearing manner. As such, the shock-absorbing power supply unit 120 is preferably formed in the upper surface of the door frame, such as a double door or a glass door, but is not necessarily limited thereto.

The first power board 121-3 is connected to an external power cable 30 to supply power. The first power board 121-3 is electrically connected to the first connection terminal 121 through the spring 121-2. The first power board 121-3 may also be connected to the central shaft 121-1 of the first connection terminal 121 through the spring 121-2 to support the physical power to mitigate an impact. The first power board 121-3 supplies power when the first connection terminal 121 and the second connection terminal 131 are connected, and cuts off the power when the first power supply terminal 121-3 is separated from each other. The first power substrate 121-3 cuts off standby power to the first connection terminal 121 when the predetermined time deviates from the first connection terminal 121 and the second connection terminal 131, thereby reducing additional power consumption. It can also be reduced.

Power supply unit 130 is formed in a bent structure is fixed to one side of the door (10). More specifically, the power supply unit 130 includes a second body 130-1 and a second connection terminal 131. The second body 130-1 is formed in a 'b' shaped structure. In this case, the second connection terminal 131 is exposed on the bottom surface of the second body 130-1, and at least one second long hole 132 is formed on the vertical surface. The bottom surface of the second body 130-1 is positioned to face the bottom surface of the first body 120-1. The power supply unit 130 may further include a spacer 130-2 in order to prevent the connection with the power supply unit 120 from being made due to the gap between the door 10 and the door frame 20. The spacer 130-2 is formed of an insulating material to form a hole corresponding to the first long hole 122. The thickness of the spacer 130-2 may vary depending on the user's design, and the spacers 130-2 may be superimposed.

When the door 10 is in the closed state, the second connection terminal 131 is connected to the first connection terminal 121 to receive power. The second connection terminal 131 is electrically connected to the second power board 131-1 in the second body 130-1. The second power substrate 131-1 serves to supply or cut off power to the door lock 110. The second long hole 132 is formed in the longitudinal direction is formed for the purpose of adjusting the height when installed in the door 10. The power supply unit 130 may be formed on the side or the top surface of the door 10. Accordingly, the power supply can be stably supplied while alleviating the impact caused by the height difference between the first connection terminal 121 of the power supply 120 and the second connection terminal 131 of the power supply 130.

Figure 7 is an exemplary view for explaining the formation of a power cable and electrode sheet on the glass door of the externally powered door lock system according to FIG.

Referring to FIG. 7, when the power supply unit 130 is formed to be separated from the door lock 110, the power cable 30 may be connected to the power supply unit 130 and the door lock 110 in the glass door 10. It is also possible to form in the form of a predetermined symbol, character, figure on one side. In this case, the power cable 30 may be connected to the suction plate and attached to the glass door 10, but is not necessarily limited thereto. In addition, the power supply unit 130 may be connected to the door lock 110 using a conductive electrode sheet 40 attached to the glass door 10. In this case, it is preferable that an electrode line is printed inside the electrode sheet paper 40. In addition, the surface of the electrode sheet paper 40 may be formed in a straight shape, such as cross-section or plant stem intersecting various shapes. Accordingly, it can be utilized as a decoration while exposing the power cable 30 to the outside. On the other hand, the power supply unit 130 may be applied to the case formed integrally with the door lock 110.

1 and 2, the externally powered door lock system 100 may further include a detector 140 and a communicator 150.

The detector 140 may detect whether the door 10 is in contact with the door frame 20 through the contact sensor 111-1, or detect a person's approach. Whether the door 10 is in contact with the door frame 20 is used as information for determining the open / closed state of the door 10. The detector 140 may detect an open / close state of the door 10 or a person's approach through a non-contact sensor using infrared rays. The detection of a person's approach is to expose a user's keypad or advertisement information. The detector 140 may also detect a battery remaining state of the internal power. This is to output a fault signal when the remaining amount of internal power is weak or not charged.

For example, the sensing unit 140 firstly detects whether the door lock 110 is opened or closed through the contact sensor 111-1 to generate a first detection signal. The detector 140 detects whether the door lock 110 is opened or closed through a non-contact sensor to generate a second detection signal. This is to detect whether the door lock 110 is broken. For example, the first detection signal may be determined to be a failure when the door 10 is open, and the second detection signal is a detection signal in a different state such as when the door is closed or vice versa. have. In this case, the sensing unit 140 may output a failure signal through the built-in speaker of the door lock 110 or the display unit 113. Accordingly, it is possible to more accurately determine whether the door lock 110 is broken.

In addition, the detector 140 detects whether the door lock 110 is opened or closed using the contact sensor 111-1 or a non-contact sensor to generate a first detection signal. The detector 140 detects whether the sensor 140 is connected to the power supply unit 120 through the power supply unit 130 and generates a second detection signal. In this case, when the first detection signal and the second detection signal do not coincide with each other, a failure signal may be output. For example, although the first detection signal is in the closed state of the door, the second detection signal may output a failure signal when no electric signal is detected. Accordingly, it is possible to more accurately determine whether the door lock 110 is broken.

FIG. 8 is an exemplary view illustrating the addition of a communication unit and an optical signal supply unit of the externally powered door lock system according to FIG. 1, and FIG. 9 illustrates a user terminal and a management server of the externally powered door lock system according to FIG. 1.
