Hereinafter, with reference to the accompanying drawings a preferred embodiment of the mechanical combined electronic locking device for a building door according to the present invention will be described in detail.

1 is a schematic configuration diagram of a mechanical combined electronic locking device for a building door according to an embodiment of the present invention, Figure 2 is an exploded perspective view of the main part of Figure 1, as shown, the locking device according to the present invention Composed of the electronic key 100 and the locking body 200, the locking body 200 is installed in the door is a locking bar 210, a key bundle 220, the actuator 230 and the electronic control means 240 It is configured to include.

The locking bar 210 is installed to be reciprocated on one side of the door D, and the front end portion of the locking bar 210 is inserted into the locking hole 310 of the bracket 300 installed on the door frame F. By being detached, it is comprised so that the door D may be locked or unlocked. In addition, a rack gear 212 is formed on one surface of the locking bar 210 in the longitudinal direction.

The key bundle 220 is installed so that the key hole 221 is exposed to the outside of the door (D) in a direction perpendicular to the locking bar 210, the rack gear 212 and the front end of the rotating shaft 222 As the gear gear is coupled to the gear, the locking bar 210 is reciprocated according to the forward and reverse rotation of the key plate 120 inserted into the key bundle 220. The door D is configured to be locked or unlocked.

On the other hand, the drive gear unit provided in the key bundle 220 may be composed of a motive gear 223 and a driven gear 226. The prime mover 223 is integrally formed at the tip of the rotation shaft 222 of the key bundle 220. In addition, the driven gear 226 has an internal gear 226a at the center of one side of the driven gear 223 to be inserted and coupled, and the rack gear 212 of the locking bar 210 in a rotating state. And gears are configured to engage. In this case, the key bundle 220 is provided inside the housing 225 so that the primary gear 223 can elastically maintain the state separated from the internal gear 226a on the same axis as the driven gear 226. It is carbonized with the spring 224.

That is, only when the key bundle 220 is pressed by the inserted key plate 120, the motive gear 223 formed at the front end of the rotation shaft 222 of the key bundle 220 is formed of the driven gear 226. Inserted into the internal gear 226a, the gears are coupled to each other so that the rotational movement of the key bundle 220 may be transmitted to the rotational movement of the driven gear 226 reciprocating the rack gear 212. On the other hand, the sliding groove 225a is formed in the housing 225 and the protrusion 220a slid along the sliding groove on the outer surface of the key bundle 220, the key bundle 220 is the housing ( 225 is to be reciprocated only a predetermined distance inside, so as not to be separated out of the housing 225.

In FIG. 2, by rotating the hinge pin 227 protruding from the center of the other side of the driven gear 226 to the hinge bracket 228 fixed to one side of the door D, the rotating motion of the driven gear 226 is achieved. Although configured to be possible, in addition to the rotational motion of the driven gear 226 may be implemented in various ways.

The actuator 230 is an element that is connected to the rear end of the locking bar 210 so as to reciprocate the locking bar 210, and includes a cylinder 231, a piston 232, a rod 233, and an electromagnet ( 234 and 235. The piston 232 is installed reciprocally in the cylinder 231, the rod 233 extending from the piston 232 is installed to penetrate the cylinder 231, the rod 233 is the locking bar The end is fixedly coupled to the rear end of the locking bar 210 in the same axis as the 210. In this case, as the piston 232 is reciprocated, the locking bar 210 is reciprocated and configured so that the tip portion of the locking bar 210 can be inserted / detached into the locking hole 310. In FIG. 2, the rod 233 and the locking bar 210 are shown to be coupled with a pin P. However, each end of the rod 233 and the rod 233 may be fixedly coupled by welding or the like. Of course.

In addition, the pair of electromagnets 234 and 235 are fixed to both ends of the cylinder 231, and are configured to reciprocate the piston 232 as power is applied.

The electronic control means 240, by applying the power to one of the electromagnet 234 and the electromagnet 235 as the set electronic signal is received, thereby reciprocating the piston 232 to the locking bar 210 ) Is a means for causing the reciprocating movement, as shown in Figure 4, the receiving antenna 241, the signal processing unit 242, the control unit 243, the relay 244 (245), the optical sensor 246 ( 247 and a power supply V1.

The pair of photosensors 246 and 247 are means for sensing the current state of the actuator 230, as shown in Figure 2, the upper and lower parts of the rod 233a extending to the rear of the cylinder 231 It consists of a light emitting sensor 246 and a light receiving sensor 247 are installed facing each other.

The receiving antenna 241 receives the electronic signal transmitted from the electronic key 100, and the signal processing unit 242 demodulates the signal received through the receiving antenna 241. And amplifies and inputs the result to the controller 243. The controller 243 determines whether the signal input through the signal processor 242 matches the set electronic signal, and if it is determined that the set electronic signal is input, the actuator 212 through the photosensors 246 and 247. After confirming the current state of 230, the actuator 230 is configured to apply the power supply V1 to one of the electromagnets 234 and 235 so that the actuator 230 is switched to the opposite state. In this case, the power supply V1 and the electromagnets 234 and 235 are configured to be connected through the relays 244 and 245, respectively, and the control unit 243 operates a relay connected to the electromagnet to be driven. In this case, it may be preferable to configure the power supply V1 to be connected to the desired electromagnet.

The electronic key 100 is configured such that the key plate 120 and the handle 110 are integrally formed, and the key plate 120 is inserted into the key hole 221 of the key bundle 220 and the key bundle 220. It is formed to operate, and the handle portion 110 is provided with a signal generating means for generating an electronic signal set in the electronic control means 24, wherein the key plate 120 is the signal And an antenna function for transmitting the electronic signal generated from the generating means.

The signal generating means, as shown in Figure 4, the power supply (V2), the relay 114, the oscillator 116, the signal processor 118 is built in the sieve handle 110 connected in series, the relay The button 112 for operating the 114 may be configured to be installed on the outer surface of the handle portion 110. At this time, the oscillator 116 is configured to generate a predetermined electronic signal set in the electronic control means 240, the signal processor 118 modulates the electronic signal generated by the oscillator 116 Configured to convert the signal into a transmittable signal. The electronic signal modulated by the signal processor 118 is output through the key plate 120 functioning as an antenna. In addition, a transmission indicator 119 is provided on an outer surface of the handle 110, and the transmission indicator 119 is connected to an output terminal of the relay 114, whereby a relay by operation of the button 112 ( The power supply V2 is supplied and turned on during operation of the 114.

Referring to the operation of the locking device according to the above configuration as follows.

When the user holding the electronic key 100 presses the button 112 on the outer surface of the handle 110, the relay 114 is switched on, so that the power supply V2 is turned on the oscillator 116 and the transmission indicator ( 119). Accordingly, while the transmission indicator 119 is turned on, the oscillator 116 generates a predetermined electronic signal, and the electronic signal is modulated into a signal that can be transmitted by the signal processor 118 and then serves as an antenna. It is output through the key plate 120.

The electronic signal output in this way is received by the receiving antenna 241 of the electronic control means 240 provided in the locking body 200, and then demodulated into a signal that can be processed by the signal processor 242, and then the control unit ( 243). At this time, the control unit 243 determines whether the signal input through the signal processing unit 242 is an electronic signal generated from a predetermined electronic key 100, that is, matches the set electronic signal, and then is set. If it is determined that the electronic signal is the same as the present state of the actuator 230 through the photosensor 246, 247, and then one of the electromagnets (234, 235) so that the actuator 230 is switched to the opposite state Make sure power is applied to the electromagnet.

In other words, in the state in which the locking of the door D is released, that is, in the state in which the tip of the locking bar 210 is separated from the locking hole 310, the locking bar 210 is in a reversed state. The rod 233 of the actuator 230 is reversed to block the light sensor 246 and 247. Therefore, the light emitting signal of the light emitting sensor 246 is not received by the light receiving sensor 247, through which the electronic control means 240 determines that the rod 233 of the actuator 230 is backward. The relay 245 is operated so that the power supply V1 is applied to the 235. In addition, the piston 232 is advanced forward by the electromagnet 235 to which the power source V1 is applied, so that the rod 233 is advanced together. As a result, the locking bar 210 is advanced, so that the tip end thereof. Is inserted into the locking hole 310 to lock the door (D).

At this time, the motive gear 223 at the tip of the key bundle 220 is in a state separated from the internal gear 226a of the driven gear 226, as shown in Figure 3 (a). Therefore, since the driven gear 226 is capable of rotating about the hinge pin 227 of the locking bar 210, the rack gear 212 of the locking bar 210 is driven gear 226 is geared. It can be easily forward movement while rotating.

In the state in which the door D is locked, that is, the front end portion of the locking bar 210 is inserted into the locking hole 310, the electronic control means 240 performs the operation opposite to the above. The front end of the locking bar 210 is released from the locking hole 310, thereby releasing the locking of the door (D).

On the other hand, when it is impossible to lock and release the door D by the electronic signal due to exhaustion, discharge or power outage of the power supplies V1 and V2, the key is integrally coupled to the electronic key 100. When the plate 120 is pressed in the state of being inserted into the key hole 221 of the key bundle 220, the key bundle 220 compresses and advances the spring 224 inside the housing 225. At this time, by rotating the rotation shaft 222 together with the key bundle 220, as shown in FIG. 3 (a), the driving gear 223 at the tip of the rotation shaft 222, which has been separated from the internal gear 226a, is shown in FIG. As shown in (b), the internal gear 226a is inserted into and coupled to the internal gear 226a.

In such a state, when the key plate 120 inserted into the key bundle 220 is rotated in the forward or reverse direction, the driven gear 223 is rotated in accordance with the rotation of the key bundle 220. 226 is rotated, so that the locking bar 210 can be moved forward or backward. Accordingly, the front end of the locking bar 210 is inserted into or removed from the locking hole 310, thereby locking the door D. And can be released.

At this time, since the rod 233 of the actuator 230 coupled to the rear end of the locking bar 210 does not have a power supply V1 applied to the electromagnets 234 and 235 capable of regulating its movement, Since the movement is free, the rod 233 of the actuator 230 is reciprocated in the same direction according to the reciprocating movement of the locking bar 210.

As can be seen by the above embodiment, by the mechanical lock electronic lock of the building door according to the present invention, by configuring the door lock installed in the building door to be used both mechanically and electronically, In addition to the convenience of the user using the electronic key, when the power supply is cut off due to exhaustion, discharge, or power outage of the battery, the door can be locked and unlocked by the key plate. There is an effect that can be improved. In addition, the present invention has the effect of preventing the loss of the mechanical key that is not used often by making the electronic key and the machine key integrally.

In the above description of the mechanical combined electronic locking device for a building door according to an embodiment of the present invention, the present invention is not limited to this, and those skilled in the art will be able to various modifications and applications.
