A fixing cover protruding from one side is inserted into and fixed to the cover hole 124 formed at the cover hole 123, and a safety cover 148 is installed to cover the lever hole 123 and protect the manual operation lever.

In addition, the lower part of the button hole 122 of the case 12 is formed with a handle hole 125 through which the rotation axis of the handle 18 passes, and an ellipse or a forced locking lock button 200 is installed and exposed under the lower part of the case hole 125. The rectangular lock button hole 126 is formed.

Therefore, a spring terminal (not shown) is inserted into and fixed to the grooves 120 to supply power from the stored battery, and a cover 121 is inserted in the upper portion to perform an automatic and manual locking function.

The assembly and operation of each of these parts will be described with reference to the accompanying drawings.

3 and 4 are views for explaining the assembly and operation relationship of the automatic operation device internal device according to the present invention, will be described in relation to each other.

First, the operation unit 14 may be largely divided into an automatic operation device and a manual operation device, the automatic operation device is a spring operation of the automatic operation button 140 and the case of the rear of the automatic operation button 140 ( 12) a bracket 141 screwed to the bracket, a bracket-shaped button lever 143 fixed on the bracket 141 to operate the motor, and a motor protruding in a C shape at the center of the bracket 141. It is provided on the mounting portion 142 and has a motor unit 144 that is interlocked with the door shaft.

In addition, the manual operation device is a manual operation lever 151 protrudes on one side, the gear fixing protrusion 152 is formed in the other center, between the rear of the case 12 and the bracket 141 Fixed and rotated circular rotate offer 150, the engaging projection 153 protruding in the L-shape on the lower circular surface of the rotate offer 150, and the fixed projection 152 is inserted and fixed to the motor portion 144 and the offer gear 154 interlocked with each other.

In addition, the offer gear 154 is installed between the bracket 141 and the rotate offer 150, and is installed on one side of the bracket 141 and interlocked with the rotating gear 145 and the shaft 146 to rotate the motor. By rotating the rotary gear 145 connected to the shaft 146 by the operation of the 144 or the manual operating lever 151 to open and close the door lock.

In addition, the forced locking device 20 is installed on the lock stopper 203 and the rear of the lock stopper 203 of the rectangular lock button hole of the case 12 through the through hole of the lock stopper 203 ( 126, a column-type forced lock button 200 protruding from the lock, a lock guide 201 protruding from both sides of the lock button 200 in the lower side, and is installed in the lower portion of the lock guide 201 A spring 204 for pushing the button 200, and the lock button 200 and the spring 204 to support the slide locking jaw 206 is formed on the back of the square shape to support the lock guide 201 The lock cover 205, the lock cap 207 for fixing the lock cover 205 and the lock button 200, and the slide projection 208 formed on the upper portion of the lock stopper 203 is interlocked up and down It is provided with a slide plate 210.

Here, the slide plate 210 has a slope 211 through which the slide protrusion 208 is inserted, and has a through hole into which a handle shaft is inserted, and an upper surface of the slide plate 210 has the rotate offer 150. The locking protrusion 153 is dug into an arc to give a space necessary for rotation, and the edge portion is provided with a jaw so that the slide plate 210 is raised during forced locking so that the locking protrusion 153 is not rotated and the shaft 146 is rotated. ), It is impossible to open by automatic and manual operation.

Therefore, when the lock button 200 supported by the spring 204 is pushed to one side from the outside, the locking projection 201 moves along the inclined surface and is fixed to one side by being caught by the slide locking jaw 206. The slide plate 210 is raised along the inclined surface and the play with the rotator offer 150 is reduced at the upper jaw, thereby being locked by the locking protrusion 153 and being pushed to the other side while pressing the lock button 200 again. When the lock is released, it is difficult to release the state inadvertently forcibly locked because there is a locking jaw (206), it is easy to operate in conjunction with each other even when the manual locking device and the automatic operation device is separated.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the automatic door lock locking device according to the present invention is composed of a power supply unit, an automatic operation and a manual device unit and a forced lock unit, but the automatic and manual device unit is installed completely separated so that the lever of the manual device operates in arc shape. In addition, the forced locking device is interlocked with the manual device, thereby preventing manual and automatic operation devices from being in operation during the forced lock, preventing malfunction of the locking device, and improving the reliability of the device.
