As shown in Figures 1 to 3, the configuration of the electronic locking device according to the first embodiment of the present invention, the body 1 is fixed to the door (not shown) and the door (not shown) A locking member 3 for locking or releasing locking by being seated or detached in a locking groove (not shown) formed at a corresponding portion of the driving unit; and a driving motor 4 for generating rotational power when power is applied; The locking member 3 is connected to the first gear 5 and the second gear 6 for transmitting and decelerating the rotational power of the drive motor 4 and the rotation shaft of the second gear 6. ) Is moved to the left or the right by a drive shaft (7) penetratingly installed inside the drive shaft) and a drive piece (71) formed on the drive shaft (7), which is mounted to surround the outer circumferential surface of the drive shaft (7). Spring 8 for moving the locking member 3 to the left or right by , Is made to be installed around the outside of the one locking member (3) includes a locking case (9) for guiding the movement in the left and right sides of the one locking member (3).

By the above configuration, the operation of the electronic locking device according to the first embodiment of the present invention is as follows.

When the user turns on the switch (not shown) to lock the door (not shown), the forward rotation of the drive motor 4 is started by applying power to the drive motor 4.

The rotational power of the drive motor 4 is transmitted to the drive shaft 7 through the first gear 5 and the second gear 6 to rotate the drive shaft 7 forward.

As shown in FIG. 1, when the driving shaft 7 is rotated forward with the driving piece 71 lying on the left side of the spring 8, the winding of the spring 8 is carried out while the driving piece 71 is rotated forward together. By digging between the true spaces, the spring 8 advances to the right along the drive shaft 7 as shown in FIG. That is, the rotational power is converted into a linear motion and transmitted.

When the spring 8 advances to the right along the drive shaft 7 and the right end touches the locking member 3, the spring 8 pushes the locking member 3 to the right, thereby locking the locking member 3 to the right. Will be moved to. At this time, the left side of the locking member 3 is guided by the inner circumferential surface of the locking member case 9.

As the locking member 3 moves to the right as described above, when the path of the locking member 3 is shifted or the path is disturbed by obstacles caused by mechanical deformation or foreign matter, The locking member 3 is driven. Therefore, the manufacturing cost can be reduced because the high-precision control motor is not used as the drive motor 4, and since the overload does not occur in the drive motor 4, the burnout of the drive motor 4 can be prevented.

As shown in FIG. 3, when the locking member 3 is completely moved to the right side, the spring 8 moves away from the driving piece 71 and is positioned on the right side of the driving piece 71. The spring 8 is no longer moved by the forward rotation, and the locking member 3 is locked to the locking groove (not shown) formed in the corresponding portion of the door (not shown).

On the other hand, when the user enters a password to open the door (not shown), the driving motor 4 is reversely rotated, such that the rotational power of the driving motor 4 is the first gear 5 and the second gear 6 It is transmitted to the drive shaft (7) through to rotate the drive shaft (7).

As shown in FIG. 3, in a state in which the driving piece 71 lies on the left side of the spring 8, when the driving shaft 7 is reversely rotated, the driving piece 71 is reversely rotated together to wind up the spring 8. By digging between the true spaces, the spring 8 is advanced left along the drive shaft 7 as shown in FIG. That is, the rotational power is converted into a linear motion and transmitted.

When the spring 8 advances along the drive shaft 7 to the left and the left end touches the locking member 3, the spring 8 pushes the locking member 3 to the left so that the locking member 3 is left. Will be moved to. At this time, the left side of the locking member 3 is guided by the inner circumferential surface of the locking member case 9.

As shown in FIG. 1, when the locking member 3 moves completely to the left side, the spring 8 moves away from the driving piece 71 and is positioned on the left side of the driving piece 71. The spring 8 is no longer moved by the reverse rotation, and the locking member 3 is released from the locking groove (not shown) formed at the corresponding portion of the door (not shown) to release the locking. ..

Figure 4 is a perspective configuration diagram of the electronic locking device according to a second embodiment of the present invention, Figure 5 is a cross-sectional structural view showing a unlocking state of the electronic locking device according to a second embodiment of the present invention, Figure 6 7 is a cross sectional structural view showing a locking progress state of the electronic locking device according to the second embodiment of the present invention, and FIG. 7 is a flat sectional structural view showing a locking completion state of the electronic locking device according to the second embodiment of the present invention.

As shown in Figures 4 to 7, the configuration of the electronic locking device according to the second embodiment of the present invention, the body 21 is fixed to the door (not shown) and the body 21 described above And a locking groove formed in the second locking member pivot 22 and the second locking member pivot 22 that allow the user to rotate the second locking member (not shown). The locking member 23 for locking or releasing the second locking member rotating part 22 by being coupled to or separated from the 221, a driving motor 24 for generating rotational power when power is applied, and the driving motor described above. The first gear 25 and the second gear 26 for decelerating and transmitting the rotational power of the 24, and are connected to the rotation axis of the second gear 26 described above, The drive shaft 27 penetrated therein and the outer circumferential surface of the drive shaft 27 described above are mounted to cover the drive shaft 27. It is raised and lowered by a drive piece 271 formed on one drive shaft 27 to surround the outside of the spring 28 for raising or lowering the locking member 23 and the locking member 23. The locking member 2 is installed using a locking groove 291 coupled to the locking piece 231 formed on the side surface of the locking member 23 while guiding the rising and falling of the locking member 23. It comprises a locking member case 29 to prevent 23 from leaving a certain area.

With the above configuration, the operation of the electronic locking device according to the second embodiment of the present invention is as follows.

After the user first locks the second locking member (not shown) by using the second locking member pivoting portion 22 to lock the door (not shown), and then the switch (not shown) ON), power is applied to the drive motor 24, the forward rotation of the drive motor 24 is started.

The rotational power of the drive motor 24 is transmitted to the drive shaft 27 through the first gear 25 and the second gear 26 to rotate the drive shaft 27 forward.

As shown in FIG. 5, when the drive shaft 271 is rotated forward while the drive shaft 271 is placed below the spring 28, the drive piece 271 is rotated forward while being wound around the spring 28. By digging between the true spaces, the spring 28 is advanced upward along the drive shaft 27 as shown in FIG. That is, the rotational power is converted into a linear motion and transmitted.

When the spring 28 is advanced upward along the drive shaft 27 and the upper end touches the locking member 23, the spring 28 pushes the locking member 23 upward, thereby locking the locking member 23 upward. Will be moved to. At this time, the lower side of the locking member 23 is guided by the inner circumferential surface of the locking member case 29.

As the locking member 23 moves upward in this manner, when the path of the locking member 23 is displaced or the path is disturbed by an obstacle caused by mechanical deformation or a foreign substance, the spring 28 is moved by the elastic force. The locking member 23 is driven. Therefore, the manufacturing cost can be reduced because the high-precision control motor is not used as the drive motor 24, and since the overload does not occur in the drive motor 24, the burnout of the drive motor 24 can be prevented.

As shown in FIG. 7, when the locking member 23 is completely moved upward, the spring 28 is located above the driving piece 271 by moving away from the driving piece 271. The spring 28 is no longer moved by the forward rotation, and the locking member 23 is seated in the locking groove 221 of the second locking member 22, thereby locking the secondary.

Therefore, the second locking member is driven by the manpower using the second locking member pivot 22, and the drive motor 24 drives only the locking member 23 for locking the second locking member pivot 22. By doing so, it is not necessary to use a large-capacity motor as the drive motor 24, and manufacturing cost can be reduced.

On the other hand, when the user enters a password to open the door (not shown), the drive motor 24 is rotated reversely, such that the rotational power of the drive motor 24 is the first gear 25 and the second gear 26 It is transmitted to the drive shaft 27 through) to rotate the drive shaft 27 in reverse.

As shown in FIG. 7, when the driving shaft 27 is reversely rotated in a state in which the driving piece 271 is placed above the spring 28, the driving piece 271 is rotated together with the winding of the spring 28. By digging between the true spaces, the spring 28 is advanced downward along the drive shaft 27 as shown in FIG. That is, the rotational power is converted into a linear motion and transmitted.

When the spring 28 advances downward along the drive shaft 27 and the lower end touches the locking member 23, the spring 28 pushes the locking member 23 downward, thereby locking the locking member 23. Will move downward. At this time, the lower side of the locking member 23 is guided by the inner circumferential surface of the locking member case 9.

As shown in FIG. 5, when the locking member 23 is completely moved downward, the spring 28 moves away from the driving piece 271 and is positioned below the driving piece 271. The spring 28 is no longer moved by the reverse rotation, and the locking member 23 is detached from the locking groove 221 of the second locking member 22 to release the locking primarily.

Next, when the user releases the secondary locking by rotating the second locking member (not shown) using the second locking member rotating part 22, the door (not shown) is opened.

As described in the above embodiment, the present invention, even if the locking member is driven slightly shifted from the locking position, it is possible to drive the locking member by using the elastic force of the spring to drive the locking member, so that the high-precision driving motor is not used to drive the locking member It is possible to reduce the cost, to prevent the overloading of the drive motor so that the drive motor is not burned out, and to drive the second locking member by using human force and driving the locking member for locking the second locking member. This has the effect that by using a drive motor, a relatively small drive motor can be used.
