[0042] FIG. 1 is a front view of a door lock device according to the present invention.

[0043] FIG. 2 is a rear view of a door lock device according to the present invention.

[0044] As illustrated in FIGS. 1 and 2, the door lock device according to the present invention is configured such that a component is mounted in an internal space formed by a front cover (10) and a rear cover (20), and a lock-unlock drive unit (30) is integrally formed.

[0045] Additionally, a hook hole (22) through which a hook (70) enters and exits is formed in the rear cover (20), and the rear cover (20) and the front cover (10) may be combined in a manner where they overlap each other, or the front cover (10) may be inserted into the rear cover (20), or the rear cover (20) may be inserted by covering the front cover (10) as shown in FIG. 2. Regardless of the combination form, a component is mounted in the internal space formed by the combination of the front cover (10) and the rear cover (20). The space for mounting the component may be formed by separating it with a partition wall or the like, or a hole may be formed in an appropriate location to insert the component.

[0046] The door lock device according to the present invention is a door lock device capable of reproducing a state in which the door is closed by human power when the hook (70) is introduced through the hook hole (22), a state in which the door is firmly closed when pulled inward (e.g., soft closing), and a state in which the door is locked for operation of a washing machine, etc.

[0047] In addition, the door lock device according to the present invention is a door lock device capable of reproducing a door open state in which the door is unlocked, the door is pushed open (e.g., soft opening), and the hook (70) is released from the door lock device.

[0048] The door lock device according to the present invention will be described in detail below through the drawings.

[0049] FIG. 3 is an internal structure diagram of a door lock device according to the present invention.

[0050] FIG. 4 is an internal cross-sectional view of a door lock device according to the present invention.

[0051] FIG. 5 is an enlarged internal cross-sectional view of a door lock device according to the present invention.

[0052] As illustrated in FIGS. 3 to 5, a door lock device according to an embodiment of the present invention comprises: a rocker (200) installed in an internal space and coupled to or separated from a hook (70) by rotation; a rocker spring (210) connected to one end of the rocker (200) to provide a restoring force according to the rotation of the rocker; a rocker slide (220) that moves linearly by providing an external force as the rocker (200) rotates; a first electrode (700) connected to one end of the rocker slide (220) to generate a signal indicating the open or closed state of the door; a slide lever (400) that moves linearly along a track formed in an engraved shape on the rear cover (20) to rotate the rocker (200); a closing lever (500) that moves linearly by being pushed by a hook (70) introduced through a hook hole (22); and a device coupled to the closing lever (500) according to the linear movement of the closing lever (500). It includes a lifting member (530) installed in the internal space that rises or falls, wherein the slide lever (400) is operated by the rising or falling of the lifting member (530).

[0053] The rocker (200) according to the present invention is configured in a ring shape and can be configured in a general shape in which a hook (70) is inserted into the interior of the ring. The rocker (200) is positioned so that the open area of ​​the rocker (200) corresponds to the hook hole (22).

[0054] According to FIG. 3, the rocker (200) has a hole formed on the right edge of the outer surface forming an arc to which a rocker spring (210) can be coupled, and as shown in FIG. 4 and FIG. 5, a rocker outer groove (270) is formed below the hole to which the rocker spring (210) can be coupled to a rocker slide (220) to be described later.

[0055] FIG. 6 is a detailed side cross-sectional view of a door lock device according to the present invention.

[0056] As illustrated in FIGS. 3 and 6, the door lock device according to the present invention further includes a rocker center rod (250) formed at the center where the rocker (200) rotates, and a hook-shaped rocker rotation hook (260) formed at one end of the rocker center rod (250).

[0057] A rocker center rod (250) is formed at the rotating center of the rocker (200) and is integrally formed with the rocker (200). The rocker (200) is connected to one end of the rocker center rod (250), and a rocker rotation hook (260) is connected to the other end. The rocker (200) and the rocker rotation hook (260) rotate around the rocker center rod (250).

[0058] As shown in FIG. 6, the rocker rotation hook (260) according to the present invention rotates in the slide lever well (440) according to the movement of the slide lever (400) and rotates by being induced by the locking wall (460).

[0059] The rocker spring (210) is connected to one end of the rocker (200) to provide a restoring force according to the rotation of the rocker (200). One end of the rocker spring (210) is connected to the rocker (200), and the other end is connected to the rear cover (20) to provide rotational restoring force. For example, when the rocker (200) rotates to achieve a locked state while the door is closed, the rocker spring (210) bends and extends toward the rear cover (20). It provides rotational force to restore the rocker (200) to its original position until it passes the bending point, and then, once it passes the bending point, it provides a restoring force in reverse to maintain the locked state of the door.

[0060] Alternatively, when the rocker (200) rotates from a closed state to an open state, the rocker spring (210) rises and bends in the opposite direction of the rear cover (20), and a restoring force acts to keep the rocker (200) in a closed state until it passes the bending point, and then a restoring force acts to keep the rocker (200) in an open state once it passes the bending point.

[0061] Furthermore, the rocker (200) in the open state is provided with a restoring force to the rocker (200) so that it immediately becomes closed when it passes the bending point of the rocker spring (210) due to the force acting from the hook (70) entering from the outside.

[0062] The rocker slide (220) moves linearly by providing an external force as the rocker (200) rotates. As shown in FIG. 5, the rocker slide (220) is installed at the bottom of the rocker (200) and the rocker spring (210) so that it moves linearly as a physical force is applied as the rocker (200) rotates.

[0063] As will be described later, the first electrode (700) connected to the rocker slide (220) generates a signal indicating the state of the rocker (200). In other words, the hook (70) is coupled to the rocker (200) to generate a signal determining whether the door is open or closed, and the signal is transmitted to the outside.

[0064] FIG. 7 is a detailed view of a slide lever according to the present invention.

[0065] As shown in FIG. 3, the slide lever (400) is coupled so as to be positioned longitudinally along the same line as the rocker rotation hook (260). The slide lever (400) moves linearly, and the thrust for linear movement is generated by a motor (40) coupled to the upper right side of the slide lever (400) and a gear part (50) connected to the worm gear of the motor (40).

[0066] More specifically, the slide lever (400) includes a slide lever gear (420) formed in a portion of the side area, a slide lever loop (430) protruding from the center of the slide lever (400) as shown in FIG. 7, and a slide lever well (440) that is recessed in the longitudinal direction to induce the rocker (200) to rotate by rotating the rocker rotation hook (260) according to the linear movement of the slide lever (400).

[0067] As shown in FIG. 3, the rotational force transmitted through the gear section (50) is transmitted to the slide lever (400) through the slide lever gear (420), and the slide lever (400) moves in a linear motion. In addition, a torsion spring (410) is installed on the edge of the slide lever (400), and the torsion spring (410) is fixed to the rear cover (20) to provide a stable restoring force according to the linear movement of the slide lever (400).

[0068] The slide lever loop (430) is formed to protrude in a roof shape in the middle area of ​​the slide lever (400), and a recessed lower loop (432) is formed in the middle of the slide lever loop (430).

[0069] A rotary switch (800) fixedly installed on the rear cover (20) is installed at the lower part of the slide lever loop (430), and the rotary switch (800) includes a switch pin (810) that returns to its original position after being tilted at a predetermined angle. The switch pin (810) is tilted by contacting the lower loop (432) formed at the center of the slide lever loop (430). However, when passing the area of ​​the lower loop (432), the switch pin (810) returns to its original position.

[0070] That is, the rotary switch (800) generates a signal indicating the direction of movement and position of the slide lever (400).

[0071] FIG. 8 is a perspective view of a closing lever according to the present invention.

[0072] FIG. 9 is a cross-sectional view of a part of a door lock device with a closing lever installed according to the present invention.

[0073] The closing lever (500) shown in FIGS. 3, 8, and 9 moves linearly upward relative to FIG. 3 by means of a hook (70) that enters through the hook hole (22).

[0074] The closing lever (500) moves linearly in the insertion space formed in the rear cover (20), and one end of the closing lever (500) is connected to the rear cover (20) by attaching a closing lever spring (510). That is, structurally, the closing lever (500) receives elastic force downwards based on FIG. 3.

[0075] As illustrated in FIG. 8, the closing lever (500) includes a first slope (501) which is a slope for raising the closing lever (500) as the hook (70) is introduced, and a second slope (502) which is a slope for lowering the lifting member (530) when the closing lever (500) is raised.

[0076] As illustrated in FIG. 9, when the hook (70) is introduced, it comes into contact with the first slope (501), and the closing lever (500) rises along the first slope (501). The closing lever (500) rises against the elasticity of the closing lever spring (510), and the lifting member (530) descends along the second slope (502) to lower its height.

[0077] A second electrode (33) of a lock-unlock drive unit (30), which will be described later, is placed on the upper part of the lifting member (530), so that as the height of the lifting member (530) decreases, the second electrode (33) is connected to an external terminal. A detailed explanation will be provided later.

[0078] FIG. 10 is a perspective view of a locking lever according to the present invention.

[0079] The locking lever (600) shown in FIGS. 3 and FIGS. 10 descends to the rocker slide (220) position when the door is in a closed state and engages with the rocker slide (220).

[0080] As illustrated in FIG. 3, the locking lever (600) may be located to the right of the previously described closing lever (500), but is not necessarily limited thereto. However, the locking lever (600) moves linearly in the insertion space formed in the rear cover (20), just like the closing lever (500), and one end of the locking lever (600) is connected to the rear cover (20) by attaching a locking lever spring (610). That is, structurally, the locking lever (600) receives an elastic force downwards relative to FIG. 3.

[0081] As illustrated in FIG. 10, the locking lever (600) has a third slope (603), which is a slope formed at one end that engages with the rocker slide (220). Correspondingly, the rocker slide (220) includes a fourth slope (224) formed on its side to engage with the third slope (603) of the locking lever (600).

[0082] Referring to FIGS. 4 and 5 described above, when the hook (70) begins to be introduced and the rocker (200) rotates clockwise, one end of the rocker slide (220) is introduced into the outer groove (270) of the rocker, and the rocker slide (220) moves linearly to the left. As shown in FIG. 5, when the rocker slide (220) finishes rotating and moving linearly, the fourth side (224) engages with the third side (603) of the locking lever (600) introduced from the side of the rocker slide (220), creating a state where the rocker slide (220) cannot move linearly, and at the same time, the rocker (200) also becomes unable to rotate.

[0083] FIG. 11 is a front view of a lock-unlock drive unit according to the present invention.

[0084] FIG. 12 is a partial perspective view of a lock-unlock drive unit according to the present invention.

[0085] The lock / unlock drive unit (30) illustrated in FIGS. 11 and 12 includes a solenoid (31) that provides linear moving thrust, an actuator (32) that moves linearly by a flange (39) connected to the solenoid (31), a left electrode (33b) that generates an operation signal of a slide lever (400) as a metal electrode installed at the edge of the actuator (32), and a right electrode (33a) that generates a signal of a locked or closed state of the door by the actuator (32).

[0086] The lock-unlock drive unit (30) is inserted into the rear cover (20) at a position covering the closing lever (500) and the locking lever (600) shown in FIG. 3.

[0087] As shown in FIG. 11, the solenoid (31) moves a flange (39) protruding from one side and moves an actuator (32) connected to the flange (39). The actuator (32) receives an elastic force to the right of FIG. 11 due to a spring member (36).

[0088] The second electrode (33) includes a right electrode (33a) that generates a signal of a locked or closed state due to the movement of the actuator (32), and a left electrode (33b) that generates a signal to operate the slide lever (400) by the rising or falling of the lifting member (530) moving along the second slope (502) of the closing lever (500) as shown in FIG. 12.

[0089] As shown in FIG. 11, a protruding ridge (34) is formed on the edge of the actuator (32) in the direction of the second electrode (33) so that the right electrode (33a) can come into contact with or not come into contact with the external terminal as the actuator (32) moves. When the actuator (32) is moved to the left, the right electrode (33a) rises along the protruding ridge (34).

[0090] When the right electrode (33a) rises, the connection with the external terminal installed under the right electrode (33a) is released.

[0091] FIG. 13 is a drawing showing the back side of a lock-unlock drive unit according to the present invention.

[0092] As shown in FIG. 13, the actuator (32) includes a stopper (35) that protrudes through the case (38) of the lock-unlock drive unit (30).

[0093] The locking projection (35) is attached to the other end of the locking lever (600) when the locking lever (600) shown in FIG. 10 is coupled with the rocker slide (220), thereby preventing the locking lever (600) from being forcibly raised. That is, the locking projection (35) engages with the locking lever (600) to ultimately achieve a locked state that prevents the rotation of the rocker (200).

[0094] Above, we have examined each component of the door lock device according to the present invention.

[0095] Hereinafter, the operation of components for implementing the locked state of a door lock device is examined through FIGS. 3 to 12.

[0096] As mentioned above, the door lock device according to the present invention implements a state where the door is closed by human power, a state where the door is automatically pulled inward and firmly closed, and a state where it is locked.

[0097] The process of distinguishing each state and generating operation and status signals for each component is explained. However, a control device (not shown) that receives the status signal and operates the component is connected.

[0098] As shown in FIG. 4, when the hook (70) passes through the hook hole (22) and enters the rocker (200), the rocker (200) rotates clockwise and the rocker slide (220) moves to the left. The first electrode (700) installed at one end of the left side is connected to an external terminal to generate a first closed state signal. The control device receives the first closed state signal. The control device recognizes that the rocker (200) is in a locked state, and as the lifting member (530) shown in FIG. 8 and 9 lowers in height along the second slope (502), the left electrode (33b) shown in FIG. 12 touches the external electrode to generate a second closed state signal. The control device receives the second closed state signal.

[0099] The control device that receives the second closed state signal drives the motor (40) shown in FIG. 3. By rotating the motor (40), the slide lever (400) moves to the left and rotates the rocker rotation hook (260) clockwise as shown in FIG. 4, causing the rocker (200) to pull the hook (70) so that the door closes automatically.

[0100] As the slide lever (400) moves to the left, the rotary switch (800) shown in FIG. 7 generates an automatic closing state signal indicating that soft closing is taking place, in which the rocker (200) automatically pulls the hook (70) as the switch pin (810) is tilted by the lower loop (432).

[0101] The control device receives an automatic closing state signal and operates the solenoid (31) shown in FIGS. 11 to 13 to pull the actuator (32) toward the solenoid (31). The right electrode (33a) is raised by the protruding jaw (34), thereby separating from the external electrode located beneath the right electrode (33a) and generating a locked state signal, which is transmitted to the control device. Additionally, as shown in FIG. 13, the catch (35) attached below the actuator (32) prevents the locking lever (600) from being forcibly raised.

[0102] The process of opening the door can be implemented through the reverse process of locking the door, and a detailed explanation is omitted.

[0103] The door lock device according to the present invention generates a signal according to the door lock status due to the organic coupling relationship between the components and automatically moves the components based on the signal to enable the opening and closing of the door.

[0104] The present invention has been described with reference to embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. For example, appropriate results may be achieved even if the described techniques are performed in a different order than described, and / or the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or replaced or substituted by other components or equivalents. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
