BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic locks and, more particularly, to a rocker structure of a portable electronic lock that allows the locking and unlocking operation of the locker-bar of the electronic lock to be simplified by motor driving.

In general, the lock is a general name for the mechanisms to be locked / unlocked by a key, and is manufactured and used in various forms according to the usage, installation form, and locking structure.

In the past, mechanical locks have become mainstream, but the disadvantages of mechanical locks, i.e. keys must be carried and locks cannot be opened if the keys are lost, in which case they must be dismantled or exchanged forcibly. Along with this, there is a problem of economic loss.

In addition, since the key insertion hole is exposed to the outside at all times, easy unlocking operation is easy through this, so that the lock structure may be more complicated and complicated in order to increase the reliability of the lock.

Therefore, various types of locks have been developed, such as dial locks that can be unlocked by matching numbers without a key, and button locks that unlock a lock using only a button operation. In particular, the button lock is unlocked when the locker bar is opened when the number that is manipulated by the button matches a predetermined password, but the button lock has no function to change or modify the password. It cannot provide a function continuously. Recently, portable electronic locks have been developed to enable the registration and change of passwords and to be used in various places while being portable.

On the other hand, the above-mentioned dial lock or button lock is also a mechanical lock structure of the locker-bar like a mechanical lock is complicated, and when locking or unlocking the lock, pull the rocker-bar directly by hand. It is inconvenient to use because it has to be pushed or pushed.

And a pair of rocker plates for locking and releasing the rocker-bars so that the other end is opened in a parallel state and a predetermined angle, and an elastic member providing elasticity to return to the parallel state in the open state of the rocker plate. do.

A pair of protrusions are formed on an upper surface of the cam member and a top plate member is formed at a corresponding position to guide the protrusion trajectory when the cam member rotates.

When the rocker-bar is moved downward in the rocker-bar unlocked state, the sensor further includes a sensor for driving the motor so that the rocker plate is paralleled by the elastic member and outputting a detection signal for locking.

Part of the outer circumferential surface of one end of the rocker-bar is formed with a locking groove for seating the inner surface of one end of the rocker plate.

According to this configuration, if the password is matched, the cam member rotates according to the driving of the motor, and when the rocker plate is opened, the rocker bar is released from the body and released. It can be seen that the lock is locked as it is.

According to the locker structure of the portable electronic lock according to the present invention having such a configuration, when a password is input from the electronic lock, the locker bar is automatically lifted up and unlocked, and when the locker bar is placed in the electronic lock body to lock the electronic lock, Since it is automatically ruled, it is possible to prevent damage due to excessive ruler / freeze operation.

In addition, the present invention can provide a convenience in use compared to the same product can be omitted because the operation of pulling the rocker-bar artificially because the locking and unlocking of the rocker-bar is made by a motor drive.

Hereinafter, the rocker structure of the portable electronic lock of the present invention will be described in detail with reference to the accompanying drawings.

An exploded perspective view of the main portion of the rocker structure for unlocking is shown.

Referring to FIG. 1, a body part 100 having a predetermined shape and a rocker bar 200 having one end coupled to the body part 100 and having a detachable structure at the other end thereof are configured. The body portion 100 is formed with a plurality of key buttons 3000 are exposed to the outside to receive a password from the user for unlocking the lock.

Next, FIGS. 2 and 3 will be described.

The rocker housing 110 is provided in the body portion 100. The rocker housing 110 is equipped with a motor 112 for driving on / off under the control of a central processing unit (CPU) not shown. In addition, a cam member 120 that rotates in the forward / reverse direction according to the motor driving is connected to the driving shaft of the motor 112. The cam member 120 has an approximately elliptical shape, and three protrusions 120a, 120b, and 120c protrude from the upper surface thereof. Among the protrusions 120a, 120b, and 120c, the protrusion 120b located at the center provides a central axis of rotation, and the protrusions 120a and 120c located at both ends thereof are upper plate members on the top of the rocker housing 110. The guide groove 130a of the 130 is inserted into the guide when the motor 112 is driven.

Thus, the circular plate-shaped guide grooves 130a are formed to be symmetrical with each other in the upper plate member 130, and a groove 130b into which the protrusion 120b located at the center is fitted is formed at the center thereof. In addition, the upper plate member 130 has a through hole 140 through which one end and the other end of the rocker bar 200 are formed.

While wrapping the cam member 120, one end is coupled by the hinge 150, and the other end holds the locking groove 210 formed at the other end of the rocker-bar 200 by driving the motor 112. A pair of rocker plates 160 are provided.

And the center is located on the same axis as the hinge 150 axis and both ends extending symmetrically is inserted into the hole (160a) formed in the rocker plate 160 is an elastic member that limits the movement of the rocker plate 160 A spring 170 is provided. That is, when the lock is in a locked state, that is, before the cam member 120 rotates, both ends of the spring 170 push the rocker plate 160 inward. On the other hand, when the lock is in the unlocked state, that is, when the cam member 120 is rotated, one end of the rocker plate 160 is opened due to the ellipse shape, and the spring 170 is elastic by the elasticity of the rocker plate 160. It will open by the angle.

The rocker-bar 200 is a conventional ruled / unlocked control means bent in a substantially '∩' shape, one end extending from the other end. And the structure that the rocker-bar 200 is moved within the body portion 100 is a general structure and will not be described in detail and briefly described as follows.

The transfer rod 224 having a locking hole 222 at one end of the rocker-bar 200 is integrally formed in a configuration in which a predetermined length is extended. And the transfer rod 224 is slidingly moved along the operation guide hole (not shown) formed in the body portion (110). A locking hole (not shown) is formed at the lower portion of the operation guide hole so that the elastic spring 226 is interposed at the lower end of the locking hole 222. The transfer rod 224 is moved by the elastic spring 226 until the catch 222 is in close contact with the ceiling surface of the catch hole.

And the other end of the rocker-bar 200 is provided with a locking groove 210 is held by the rocker plate 160. That is, when the locker plate 160 is inserted into the locking groove 210, the lock is in a locked state, and when the rocker plate 160 is separated from the locking groove 210, the lock is in an unlocked state.

On the other hand, the sensor 180 is mounted on one side of the rocker housing 110. The sensor 180 is also connected to the CPU, and the CPU controls the driving of the motor 112 according to the sensing operation of the sensor.

The sensor 180 detects when one end of the rocker-bar 200, for example, a portion in which the transfer rod 224 is formed, moves downward to be locked in the unlocked state. Therefore, when the rocker-bar 200 moves downward, the sensor 180 detects this and the CPU drives the motor 112 according to the detection result so that the rocker plate 160 has the other end of the rocker-bar 200. To be caught in the engaging groove 210 formed in.

Next, the operation of the rocker structure of the portable electronic lock having the above configuration will be described.

First, if the initial state, that is, the lock is kept in a locked state, both ends of the rocker-bar 200 is inserted into the body portion 100, in this case the locking groove formed on one end of the rocker-bar 200 ( 210, the pair of rocker plates 160 are fitted. In other words, the locked state refers to a state in which the pair of rocker plates 160 are almost equilibrium and a part thereof is seated in the locking groove 210. That is, as shown in FIG.

In the state as shown in FIG. 4, when the key of the key button 300 is operated to unlock the lock, the CPU checks whether the password is set in advance. When the password matches the password, the CPU rotates the motor 112 in a predetermined direction, and then the cam member 120 connected to the drive shaft of the motor 112 also rotates in the same direction as the rotation direction.

That is, as shown in FIG. Referring to FIG. 5, as the elliptical cam member 120 rotates, the cam member 120 is vertically positioned in a long radial direction, and thus the rocker plate 160 that presses both sides of the cam member 120 is also hinged. The opposite part starts to open about the (150) axis.

At this time, the projections 120a and 120c of the cam member 120 move along the guide groove 130a formed in the upper plate member 130.

When the rocker plate 160 is opened by rotating the cam member 120 as described above, one end of the rocker plate 160 is separated from the locking groove 210 formed in the rocker-bar 200. Thus, the rocker-bar 200 is moved upward by the elastic force of the elastic spring 216 at the lower end of the rocker-bar 200. Thus the lock is released.

On the contrary, when the lock is unlocked, the rule is to be adjusted.

One end of the rocker-bar 200 is completely separated from the body portion 100. When the rocker-bar 200 is pushed into the body portion 100 in this state, one end and the other end of the rocker-bar 200 enter the body portion 100. At this time, the sensor 180 detects that one end of the rocker-bar 200 is inserted.

The detection result signal of the sensor 180 is transmitted to the CPU. The CPU drives the motor 112 in reverse rotation according to the detection result signal. The protrusions 120a and 120c formed on the cam member 120 are guided in opposite directions along the guide groove 130a according to the reverse rotation of the motor 112. That is, as shown in FIG. 4 in the state of FIG. 5. Then, the rocker plate 160 is restored to its initial state by the elastic restoring force of the spring 170, and at this time, one end of the rocker plate 160 is seated in the locking groove 210 of the rocker-bar 200. It is locked.
