BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic installation layout diagram of a digital door lock.
Fig. 2 (a) is a schematic side sectional view showing a digital door lock lock state, and Fig. 2 (b) is an unlocked state.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, a digital door lock is installed on a door, and an interphone 300 is installed on a wall surface adjacent to a door, as shown in the figure. An ordinary AC power line is wired to the interphone 300. Therefore, in order to use the DC power source required in the digital door lock, the AC power supply line of the interphone 300 is extended to provide a DC adapter on the wall surface, a DC power supply line 210 is drawn out from the DC adapter, . However, if another AC power line is already passing near the receiving plate unit 200, the DC adapter may be installed using the AC power line, and the DC power supply line 210 may be taken out of the DC adapter.

2 (a) is a side cross-sectional view showing a locked state of the door frame and a digital door lock system installed on the door, and Fig. 2 (b) is a schematic side sectional view showing the unlocked state. As shown in the figure, the digital door lock system includes an input unit (not shown), a control unit (not shown) and a secondary battery unit (not shown) connected to the motis unit 100 and the motis unit 100, Thereby charging the secondary battery. The charged secondary battery unit (not shown) supplies power to the input unit, the control unit, and the motis unit 100.

Generally, the power source of a conventional digital door lock system is a small-sized primary battery, and the life of the digital door lock system is replaced. However, in the present invention, the power source of the digital door lock system is used as a secondary battery which can be charged and used repeatedly instead of a small primary battery. Of course, it can be replaced by a large-capacity capacitor instead of a secondary battery.

The digital door lock is protruded and received toward the receiving plate unit 200 as shown by the operation of a driving motor (not shown) or a solenoid (not shown) interlocked with the reciprocating motion of the dead bolt 110 in the locked state, . The locked dead bolt 110 is concentrated on the side by the action of opening the door. Therefore, it is preferable that the sliding contact surface 130 connecting the DC power source is provided on the upper and lower surfaces of the dead bolt 110 which receives little force.

The sliding contact surface 130 in which DC (+) and negative (-) power sources are relayed may be provided on either one of the upper and lower surfaces of the dead bolt 110. In this embodiment, A sliding contact surface 130 through which DC (+) and (-) power sources are relayed is provided.

In order to provide the sliding contact surface 130, since the deadbolt 110 is made of a metal having good conductivity, the deadbolt insulator 120 surrounded by the insulator up to the top, bottom, or end of the deadbolt 110 is formed . It is preferable that the deadbolt insulator 120 is formed into a C-shape by injection plastic or the like, and is wrapped to the upper and lower surfaces and the end of the dead bolt 110 and is adhered with an adhesive or the like. The sliding contact surface 130 may be formed integrally with the metal foil on the upper and lower surfaces thereof when the dead bolt insulator 120 is formed.

The second resilient contact 140 and the first resilient contact 220 are elastically supported on the respective sliding contact surfaces 130. The second resilient contacts 140 are installed on the upper and lower surfaces of the dead bolts 110 located inside the motis unit 100 and the first resilient contacts 220 are installed using the upper space of the receiving plate unit 200 And is provided such that contact is made between upper and lower surfaces in which the protruding dead bolts 110 are received. That is, when the dead bolt 110 is advanced to the receiving plate unit 200, the first elastic contact point 220 and the second elastic contact point 140 simultaneously contact the sliding contact surface 130, The sliding contact surface 130 may be separated from the first elastic contact 220 when the bolt 110 is retracted from the receiving plate unit 200.
The first elastic contact 220 is connected to the DC power supply line 210 and the second elastic contact 140 is connected to the charging power supply line. Therefore, in the locked state of the digital door lock, that is, in the state where the receiving plate unit 200 of the dead bolt 110 is protruded, the DC power supply line 150 contacts the second elastic contact 140, the sliding contact surface 120, (220), and the DC power is always supplied to the charging power supply line (150) to charge the secondary battery. It is preferable that the (+) and (-) DC power supply lines 210 drawn into the receiving plate unit 200 are connected from the adjacent interphone DC power supply line 310 without providing a separate DC power supply unit. It can be pulled out from the adjacently installed DC adapter separately.

2 (b) is a side sectional view showing the release state of the digital door lock. As shown in the figure, when the digital door lock is released by the operation of the input unit, the dead bolt 110 is driven by a driving motor Back to the motis unit 100 by the operation of the solenoid (not shown) or the solenoid (not shown). The first elastic contact 220 of the receiving plate unit 200 is disconnected and the DC power supply of the DC power supply line 210 is cut off and the charging voltage of the charging power supply line 160 is lowered DC power is also cut off. Normally, the digital door lock is temporarily released, and when the door is closed, the DC contact is supplied to the secondary battery while the elastic contact 140. 220 contacts the sliding contact surface 130 immediately.

The sliding contact surface 130 forms a contact when sliding the dead bolt 110 and divides the upper and lower surfaces of the dead bolt insulator 120 into a positive power source and a negative power source to lower the electrical contact resistance, It is preferable to fix it.

The first elastic contact 220 and the second elastic contact 140 are preferably leaf springs of a movable plate having excellent elasticity and low electrical resistance. The contact portion is elastically supported on the sliding contact surface 130, It is preferable to bend in a shape.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
