The present invention relates to a digital door lock, and more particularly, to a digital door lock in which a cover portion is slid.

Recently, with the rapid development of information technology, the door lock field, which is a door lock device, has also been applied to information technology.

In other words, the digital door lock, which is a product to which information technology is applied, has been released.

Such a digital door lock opens and closes the door by using a password, a card ID, or a fingerprint instead of a conventional key. Therefore, when using the digital door lock, there is an advantage that does not need to carry a key. In recent years, the use of digital door locks has increased rapidly.

On the other hand, the conventional digital door lock is provided with a number input section composed of a plurality of buttons so that most of the password can be entered.

In addition, when the number input unit composed of such a plurality of buttons is directly exposed to the outside, the appearance of the digital door lock may not be beautiful, and foreign matters may be caught between the plurality of buttons, thereby preventing the operation of the buttons. The number input section is selectively exposed by the cover. That is, the number input part of the conventional digital door lock is covered so as not to be directly exposed to the outside by a cover which slides a predetermined distance.

1 to 3, the digital door lock 50 according to the present invention is composed of the outer module, such as the door, the outer module mounted on the outdoor side, the inner module, such as the door, the inner module mounted on the indoor side. .

The outer module is a portion in which a user inputs predetermined data such as a password to open a door, and includes an outer housing 10, a cover 20 sliding from the outer housing 10, and a semi-automatic cover of the cover 20. A torsion spring 30 for sliding.

Specifically, the outer housing 10 is installed long in the vertical direction, such as the door. Thus, the cover 20 slides in the vertical direction along the longitudinal direction of the outer housing.

The outer front surface of the outer housing 10 includes a first input unit 12 for inputting a password, that is, a number input unit, and a second input unit 11 for inputting data such as a card ID or a fingerprint. do. Therefore, the user inputs data into the door lock through the first input unit 12 and the second input unit 11. In this case, the first input unit 12 may be located at the center of the outer front of the outer housing 10, the second input unit 11 may be located at the lower side of the outer front of the outer housing 10.

In addition, a control unit (not shown) connected to the first input unit 12 and the second input unit 11 is provided inside the outer housing 10. Therefore, when the user inputs data into the door lock through the first input unit 12 and the second input unit 11, the input data is transmitted to the control unit. Accordingly, the controller determines whether the input data matches the preset data, and transmits various signals to the above-described inner module side according to the determination value.

In addition, various parts for the above-described cover 20 and the torsion spring 30 are further provided on the outer side of the outer housing 10. In one embodiment, the outer side of the outer housing 10, the sliding hole 13 for coupling and sliding the cover 20 is formed, respectively, and the front of the outer housing 10 to stop the sliding of the cover 20 The mounting stop 14 for coupling the cover stopper 15 and one end of the torsion spring 30 is formed. Here, the sliding holes 13 are formed on both sides of the outer housing 10, respectively, and are formed along the longitudinal direction of the outer housing 10. Therefore, the cover 20 slides along the sliding hole 13. The cover stopper 15 and the mounting protrusion 14 are provided on the upper side of the first input unit 12 of the front surface of the outer housing 10. Preferably, the cover stopper 15 and the mounting protrusion 14 may be provided at both front edges of the outer housing 10, respectively. In this case, the cover stopper 15 may be a bolt protruding from the lower portion of the outer housing 10 to the upper portion of the outer housing 10 by a predetermined distance.

The cover 20 is coupled to the outer housing 10 so as to cover the first input unit 12, that is, the number input unit for inputting a password, and is coupled to reciprocate a certain distance from the outer housing 10 to the upper side thereof.

Specifically, sliding protrusions 21 are formed on both inner sides of the cover 20 to be fitted into the sliding holes 13 of the outer housing 10. Therefore, the cover 20 is coupled to the outer housing 10 by the sliding protrusion 21 is fitted into the sliding hole 13, the sliding protrusion 21 is along the sliding hole 13 Is sliding.

In addition, a locking portion 22 that is caught by the cover stopper 15 when the cover 20 slides is provided inside the cover 20. Therefore, the sliding section of the cover 20 may be defined by the locking portion 22 and the cover stopper 15. In this case, the locking portion 22 may be provided at an inner lower end of the cover 20, and may be a protrusion integrally formed with the cover 20.

In addition, the mounting groove 23 for coupling with the other end of the torsion spring 30 is formed inside the cover 20. In this case, the mounting groove 23 may be formed in the inner central portion of the cover 20.

The torsion spring 30 is interposed between the outer housing 10 and the cover 20, one end of which is rotatably connected to the outer housing 10, and the other end of the torsion spring 30 rotates to the cover 20. It is connected to be possible to play a role of applying an elastic force of a predetermined size in the sliding direction of the cover 20 to the cover 20 when the cover 20, that is, serves to make the cover 20 semi-automatic sliding. .

Specifically, the torsion spring 30 has a body portion 32 wound in a vortex shape, a first end portion 34 extending to one side from the body portion 32 and a second portion extending from the body portion 32 to the other side. Consists of two ends 36, the first end 34 is rotatably coupled to the mounting projection 14 of the outer housing 10 by a first fixing screw 43, the second end 36 It is rotatably coupled to the mounting groove 23 of the cover 20 by the second fixing screw (45).

Accordingly, the first end 34 of the torsion spring 30 is rotated only by a predetermined angle in a state of being positioned only in the mounting protrusion 14 of the outer housing 10 when the cover 20 slides, and the torsion spring 30 The second end 36 of the cover 20 is rotated by a predetermined angle in the mounting groove 23 of the cover 20 during the sliding of the cover 20 is moved a predetermined distance in accordance with the position movement of the cover 20. Therefore, when the cover 20 slides a predetermined distance in one direction, the torsion spring 30 interposed between the cover 20 and the outer housing 10 is very unstable because its ends 34 and 36 are close to each other. Since the gap between the ends (34, 36) to the original state in order to relieve the unstable state, the cover 20 can be semi-automatic sliding in the sliding direction by this spaced apart force. As a result, the cover 20 is able to slide semi-automatically by the force of the torsion spring 30, that is, the elastic force.

On the other hand, the inner module (not shown) includes a locking unit for selectively locking the door and a battery unit for supplying power to the locking unit. The locking unit is electrically connected to the control unit of the aforementioned outer module, and selectively locks the door according to the control of the control unit.

Specifically, when the user inputs predetermined data to the control unit through the first input unit 12 or the second input unit 11, the control unit determines whether the input data matches the preset data, and then applies the determined value. Therefore, different signals are transmitted to the locking unit. For example, when the data input by the user matches the preset data, the controller transmits a signal corresponding to 'unlocking the door' to the locking unit according to the determination value. Thus, the locking unit receives the signal to unlock the door. However, if the data input by the user does not match the preset data, the control unit transmits a signal corresponding to 'keep access lock kept' to the locking unit according to this determination value. Therefore, the locking unit receives this signal and keeps the door locked.

As mentioned above, although the present invention has been described with reference to the illustrated embodiments, it is only an example, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the scope of the present invention should be defined by the appended claims and their equivalents.

As described above, in the digital door lock of the present invention, since the torsion spring is interposed between the outer housing and the cover, the elastic force of the torsion spring is applied to the sliding cover when the user slides the cover by a predetermined distance. Thus, the sliding cover is semi-automatically slid in the sliding direction by the elastic force of the torsion spring. Therefore, according to the present invention, there is an advantage that even the elderly and children can slide the cover of the digital door lock very easily.
