Description

Lock device

Technical Field

The present application relates to locks, and more particularly to a lock device for two objects that are movable relative to each other.

Background

Generally, the track assembly may be used in a rack system of a home, office, or electronic device. The sliding rail assembly comprises a first rail and a second rail which are respectively arranged on a first object and a second object, such as a cabinet body and a drawer, so that the drawer can be opened or closed relative to the first rail and/or the cabinet body through the second rail. Depending on the needs, it is sometimes undesirable for the market or user to have the second rail (second object) arbitrarily operated from a predetermined position relative to the first rail (first object) to leave the predetermined position.

For example, US 8,328,299B2 discloses a drawer slide and lock mechanism. The lock mechanism is an electronic lock. As can be seen from fig. 1 of the scheme, the drawer slide includes an outer rail and an inner rail. The inner rail can be in a folding position relative to the outer rail. Wherein the rear end of the inner rail is provided with a pin. In another aspect, a lock mechanism includes a latch receiver, a lever arm, and a motor. Wherein, as shown in fig. 1 and 2 of the document, the latch receiver can be in a first position, and in the first position, the latch receiver is in a state of being used for capturing the pin of the inner rail, and as shown in fig. 3 of the document, once the motor receives an electronic control signal, the motor can drive the lever arm to rotate, so that the top of the lever arm can be linked and push the latch receiver to rotate from the first position to the second position so as to lock the pin of the inner rail. According to this arrangement, the inner rail can be locked in the retracted position relative to the outer rail, i.e. the inner rail cannot be moved away from the retracted position relative to the outer rail.

It is worth mentioning that this patent also discloses a manual release that extends or is exposed out of a housing of the lock mechanism; when the power supply to the motor is lost or the electronic parts are damaged, the manual release piece is pulled by a user to drive the lever arm to an unlocking position, so that the latch receiving piece can return to the first position to unlock the pin of the inner rail, and the inner rail can leave the folding position.

As disclosed in us patent publication No. 2019/0063113A1, an electronic lock is disclosed in which a motor controls a lock plunger to lock or unlock the lock plunger, and a pull cord manual unlocking mechanism assembly is additionally provided for a user to pull to drive the lock plunger from locking to unlocking.

Depending on market demands or different ways of operating the structure, it is sometimes undesirable to implement the lock function in the manner of the above-mentioned patent, and as mentioned above, this type of electronic lock requires another set of mechanical structure means (e.g. the above-mentioned manual release) for manual unlocking when the power supply is lost or the electronic parts are damaged, and the unlocking mechanism is activated by an external force. Therefore, how to develop a product with different types becomes a considerable issue.

Disclosure of Invention

The present application is directed to a lock device that can be applied to a first object and a second object that are relatively movable.

According to one aspect of the present application, a lock device for use with a first object and a second object that are relatively movable includes a first member and a second member. The first member is movably in one of a locked state and an unlocked state; the second member can drive the first member to move from the locking state to the unlocking state in response to the second member moving to a preset position from a folding position to an opening direction relative to the first member.

According to another aspect of the present application, a lock device for a piece of furniture including a first object and a second object movable relative to each other, and a driving device for providing a pressing force of the second object relative to the first object in a closing direction at a closing position for opening the lock device includes a first member and a control module. The control module is used for driving the first component to be in one of a locking state and an unlocking state; when the first component is in the locking state, the second object cannot be pressed from the folding position along the folding direction relative to the first object to be opened; when the first component is in the unlocking state, the second object is allowed to be pressed from the folding position along the folding direction relative to the first object to be opened.

According to yet another aspect of the present application, a lock device is adapted to be associated with a communication device, the lock device including a base, a first member, and a control module. The first component is movably arranged on the base; the control module comprises a first electromagnet and a second electromagnet; when receiving an unlocking signal of the communication device, the control module drives the first component to an unlocking state through the first electromagnet; when a locking signal of the communication device is received, the control module drives the first component to a locking state through the second electromagnet.

Detailed Description

As shown in fig. 1 and 2, a lock device 20, such as a smart lock device or an electronic lock, is suitable for a piece of furniture 22, and the piece of furniture 22 includes a first object 24 and a second object 26 that are movable relative to each other.

Preferably, a third object 28 is movably mounted between the first object 24 and the second object 26. Here, the first object 24 is taken as a first rail (e.g. a fixed rail), the second object 26 is taken as a second rail (e.g. a movable rail), and the third object 28 is taken as a third rail (e.g. a middle rail), but the implementation is not limited thereto. The first object 24, the second object 26 and the third object 28 are longitudinally displaceable relative to each other and together form a slide assembly 23.

Preferably, the first item 24 is arranged (e.g., secured) on a cabinet 30, and the second item 26 is configured to carry a drawer 32. Wherein the drawer 32 is in an extended position E relative to the first object 24 (or cabinet 30) through the second object 26.

Preferably, the first object 24 includes an extension 34 and the second object 26 includes a carrier 36.

As shown in fig. 3 and 4, the second object 26 can be at a folding position R relative to the first object 24. In the retracted position R, the position of the carrying portion 36 of the second object 26 substantially corresponds to the extending portion 34 of the first object 24 (as shown in fig. 3).

Preferably, the lock device 20 is removably mounted to the first article 24. For example, the lock device 20 has a mounting feature 40, and a side wall 35 of the extension 34 of the first object 24 has a mounting structure 42 that is capable of being mounted to the mounting feature 40, where one of the mounting feature 40 and the mounting structure 42 is a protrusion, and the other of the mounting feature 40 and the mounting structure 42 is a slot, for example, but not limited to, a slot.

Preferably, the lock device 20 has a housing 44 that can be used to cover most of the associated components of the lock device 20 for protection.

Preferably, the furniture 22 further includes a fitting 46, and the fitting 46 is detachably mounted to the carrier 36 of the second object 26. For example, the fitting 46 has a connection feature 48, and the carrier portion 36 of the second object 26 has a connection structure 50 that can be mutually mounted with the connection feature 48, where one of the connection feature 48 and the connection structure 50 is a slot, and the other of the connection feature 48 and the connection structure 50 is a protrusion, for example, but not limited to, a practical implementation.

Preferably, the fitting 46 includes an auxiliary portion 52 (shown in FIG. 4), and the auxiliary portion 52 is configured to cooperate with the lock device 20. The auxiliary portion 52 is, for example, a protrusion, but is not limited in implementation.

As shown in fig. 5, when the second object 26 is in a push-open (push-open) configuration with respect to the first object 24, and the second object 26 is in the retracted position R with respect to the first object 24, a space G is formed between the drawer 32 and the cabinet 30, through which a user can move with respect to the cabinet 30 by pressing the drawer 32, so that the drawer 32 can be opened with respect to the cabinet 30.

Further, the furniture 22 includes a driving device 54 for providing the second object 26 to be opened by being pressed in a folding direction D1 relative to the first object 24 at the folding position R. Specifically, the driving device 54 is disposed on the second object 26, and the driving device 54 includes a resilient member 56 and a locking mechanism 58. The resilient member 56 provides a resilient force F, and the locking mechanism 58 is operable in one of a detent state (FIG. 5) and an unlatch state (FIG. 6). When the locking mechanism 58 is in the engaged state, the elastic member 56 stores the elastic force F. When the locking mechanism 58 is in the disengaged state, the resilient member 56 releases the resilient force F. Specifically, when the drawer 32 is at the retracted position R relative to the cabinet 30 and the gap G is still maintained between the drawer 32 and the cabinet 30, the locking mechanism 58 is in the locking state.

As shown in fig. 6 and 7, when a user applies a pressing force K to the drawer 32 (or the second object 26) along the folding direction D1 to make the drawer 32 (or the second object 26) reach an overpressure position X, the locking mechanism 58 of the driving device 54 is operated to switch from the above-mentioned locking state to the unlocking state. When the pressing force K is stopped, the elastic member 56 of the driving device 54 immediately releases the elastic force F, so that the drawer 32 is opened from the overpressure position X relative to the cabinet 30 and displaced along an opening direction D2 by the elastic force F, and the drawer 32 forms an extending distance L relative to the cabinet 30, which is a so-called pressing-opening function, for example, the drawer 32 may be located at the extending position E relative to the cabinet 30. The direction of the elastic force F of the driving device 54 is opposite to the folding direction D1.

As shown in fig. 8 and 9, the lock device 20 includes a first member 60 and a control module 62. Here, the lock device 20 further includes a second member 64.

Preferably, the lock device 20 further comprises a base 66, and the control module 62, the first member 60 and the second member 64 are disposed on the base 66. Wherein the base 66 has the mounting feature 40; the control module 62 includes at least one electromagnet, here, a first electromagnet a and a second electromagnet B are taken as examples, but the number of the implementation is not limited; the first member 60 and the second member 64 are, for example, swing arms, and the first member 60 and the second member 64 are movably mounted on the base 66, for example, the first member 60 and the second member 64 can be pivotally connected to the base 66 via a first shaft M1 and a second shaft M2, respectively. The first member 60 has a first section 60a and a second section 60B, the first shaft M1 is located between the first section 60a and the second section 60B of the first member 60, and the first section 60a is configured with a metal piece 67 (as shown in fig. 9), and the metal piece 67 is located in a space S between the first electromagnet a and the second electromagnet B; on the other hand, the second member 64 has a first section 64a and a second section 64b, and the second axis M2 is located between the first section 64a and the second section 64b of the second member 64.

Preferably, the lock device 20 further comprises a shackle 68, a resilient member 70, a first sensor 72, and a second sensor 74 disposed on the base 66. Wherein the latch 68 is longitudinally movable relative to the base 66, and the latch 68 comprises at least one wall, such as a first extension wall 76a and a second extension wall 76b, and preferably, an intermediate portion 78 between the first extension wall 76a and the second extension wall 76b, the first extension wall 76a, the second extension wall 76b and the intermediate portion 78 together define a path T having an inlet 80 and an outlet 82 (as shown in fig. 8), and preferably, the intermediate portion 78 is a protrusion and has a contour similar to a heart shape, but is not limited thereto; the elastic member 70 provides an elastic force to the latch 68; the first sensor 72 and the second sensor 74 may be electronic switches, such as proximity switches or micro switches, but are not limited in implementation. Further, the first sensor 72 has a first elastic sensing portion 72a, and the second sensor 74 has a second elastic sensing portion 74a.

Preferably, the lock device 20 further includes an intermediate member 84 and a slider 86. Wherein the intermediate member 84 is disposed on the base 66, for example, the intermediate member 84 is fixedly coupled to the base 66 via at least one fixing member 87. The intermediate member 84 is sandwiched between the base 66 and the slider 86, the intermediate member 84 has a bottom and a top, and a predetermined space 88 communicating the bottom and the top, the predetermined space 88 being, for example, an opening, but is not limited in implementation; the bottom of the intermediate member 84 faces the latch 68. The predetermined space 88 of the intermediate member 84 corresponds to the path T of the latch 68, and the top of the intermediate member 84 is adapted to support the slide 86, preferably the top of the intermediate member 84 has a track 90; the slide 86 is movable along a track 90 of the intermediate member 84. Preferably, the track 90 includes a longitudinal path 90a and a curved path 90b that communicates with the longitudinal path 90a (as shown in fig. 8). Preferably, the slider 86 includes a holding portion 92, a first leg 93 and a second leg 94, the holding portion 92 is configured to cooperate with the auxiliary portion 52 of the accessory 46, and the first leg 93 and the second leg 94 are configured to cooperate with the track 90 of the intermediate member 84. Preferably, a hook 96 is movably mounted on the slider 86, and the hook 96 includes a first portion 96a and a second portion 96b, the first portion 96a extends through a portion of an installation space 95 (shown in fig. 9) of the slider 86, and the second portion 96b extends through the predetermined space 88 of the intermediate member 84 to be matched with the path T of the lock 68 (shown in fig. 8).

As shown in fig. 10 and 11, since the lock device 20 is mounted to the first object 24 via the mounting feature 40 and the fitting 46 is mounted to the second object 26, the fitting 46 is also considered to be in the retracted position R relative to the lock device 20 when the second object 26 (drawer 32) is in the retracted position R relative to the first object 24 (cabinet 30). Wherein, when the fitting 46 is at the retracted position R relative to the lock device 20, the holding portion 92 of the slider 86 can hook the auxiliary portion 52 of the fitting 46.

As shown in fig. 12, the lock device 20 further includes a power module 98, and the power module 98 is configured to provide an electrical power 100 to the control module 62. A communication device 102 may be communicatively coupled to the lock device 20 via wireless or wired means for controlling the control module 62. The communication device 102 is, for example, a mobile phone, a tablet or a smart watch, but is not limited in implementation.

As shown in fig. 13 and 14, the first member 60 is movably disposed in one of an unlocked state Y1 (fig. 13) and a locked state Y2 (fig. 14).

Preferably, the control module 62 is configured to drive the first member 60 to be in the unlocked state Y1 or the locked state Y2.

Preferably, as shown in fig. 13, when the lock device 20 receives an unlock signal of the communication device 102, the control module 62 is energized via the first electromagnet a to drive the first member 60 to the unlock state Y1. Specifically, the first electromagnet a attracts the metal piece 67 on the first section 60a of the first member 60, so that the first member 60 pivots through the first axis M1 to a first predetermined direction R1 by an angle, and the second section 60b of the first member 60 is not blocked by the path T of the lock 68.

Preferably, as shown in fig. 14, when the locking device 20 receives a locking signal of the communication device 102, the control module 62 is energized via the second electromagnet B to drive the first member 60 to the locked state Y2. Specifically, the second electromagnet B attracts the metal piece 67 on the first section 60a of the first member 60, so that the first member 60 pivots through the first axis M1 to a second predetermined direction R2 by an angle, and the second section 60B of the first member 60 blocks the path T of the lock 68. Wherein the second predetermined direction R2 is opposite to the first predetermined direction R1.

As shown in fig. 10 and 13, when the first member 60 is in the unlocked state Y1 (as in fig. 13), the second object 26 (since the fitting 46 is mounted to the second object 26, fig. 10 only shows that the fitting 46 represents the second object 26) allows the first object 24 (since the lock device 20 is mounted to the first object 24, fig. 10 only shows that the lock device 20 represents the first object 24) to be pressed in the folding direction D1 from the folding position R to be opened.

Specifically, when the first member 60 is in the unlocked state Y1, the second section 60b of the first member 60 is not blocked in the path T of the latch 68 (see fig. 13). When the accessory 46 is in the retracted position R relative to the lock device 20, the holding portion 92 of the slider 86 can hook the auxiliary portion 52 of the accessory 46, and because the holding portion 92 of the slider 86 hooks the auxiliary portion 52 of the accessory 46, the second part 26 (drawer 32) can link the slider 86 to move from the retracted position R toward the retracted direction D1 relative to the first object 24 (cabinet 30) through the accessory 46, during which the second section 60b of the first member 60 does not block the path T of the lock 68, so that the second portion 96b of the hook 96 can move along the path T from a corresponding retracted position R '(as shown in fig. 13) until the second part 96b of the hook 96 on the slider 86 is at a corresponding position X' on the path T when the second part 96b of the hook 96 on the slider 86 is moved toward the overpressure position X relative to the second object 96b (see fig. 6) along the path T2 when the second part 96b of the hook 96b on the slider 86 is moved away from the path T along the path X2 relative to the path T. It will be appreciated that when the first member 60 is in the unlocked state Y1 and the second object 26 (drawer 32) is in the retracted position R, the user is allowed to push open the second object 26 (drawer 32).

As shown in fig. 10 and 14, when the first member 60 is in the locked state Y2 (as shown in fig. 14), the second object 26 cannot be opened by being pressed in the closing direction D1 from the closing position R relative to the first object 24.

Specifically, when the first member 60 is in the locked state Y2, the second section 60b of the first member 60 blocks the path T of the lock 68, so that the second portion 96b of the lock hook 96 is blocked, such that the second object 26 (drawer 32) cannot be displaced to the overpressure position X in the folding direction D1 relative to the first object 24 (cabinet 30) (i.e., the second portion 96b of the lock hook 96 on the slider 86 cannot be moved from the corresponding folding position R 'to the corresponding overpressure position X' of the path T), and thus the press-opening function cannot be activated. It can be seen that when the first member 60 is in the locked state Y2 and the second object 26 (drawer 32) is in the retracted position R, the user cannot press open the second object 26 (drawer 32).

Preferably, the first sensor 72 is configured to sense whether the second object 26 is in the retracted position R (as shown in fig. 10, since the fitting 46 is mounted to the second object 26, fig. 10 only shows that the fitting 46 represents the second object 26), and the first member 60 is controlled to be in the locked state Y2 (as shown in fig. 14) accordingly. For example, when the second object 26 (the fitting 46) is at the retracted position R relative to the first object 24 (the locking device 20), the first elastic sensing portion 72a of the first sensor 72 is pressed by a predetermined portion 104 of the slider 86, so as to sense that the second object 26 (the fitting 46) is at the retracted position R (as shown in fig. 10), and the second electromagnet B is energized accordingly, so that the first member 60 is in the locked state Y2 (as shown in fig. 14).

As shown in fig. 14 and 15, the second member 64 can drive the first member 60 to move from the locked state Y2 (shown in fig. 14) to the unlocked state Y1 (shown in fig. 15) in response to the second object 26 (drawer 32) being displaced from the retracted position R (which can be matched with fig. 10) to a predetermined position P (shown in fig. 15) in the opening direction D2 relative to the first object 24 (cabinet 30).

For example, when the power supply 100 is lost (e.g., the power module 98 is not powered or the power supply 100 is stopped accidentally to the control module 62) or the related electronic components are damaged, and the first member 60 is in the locked state Y2 (as shown in fig. 14), the second member 64 can be used to drive the first member 60 (as shown in fig. 15) from the locked state Y2 (as shown in fig. 14) to the unlocked state Y1 (as shown in fig. 15) in response to the second member 64 being moved from the retracted position R to the open direction D2 relative to the first member 24 (cabinet 30) in response to the second member 26 (drawer 32). In other words, the user only needs to displace the second object 26 (drawer 32) from the closing position R to the opening direction D2 to the predetermined position P relative to the first object 24 (cabinet 30), and can drive the first member 60 through the second member 64, so that the first member 60 moves from the locked state Y2 to the unlocked state Y1, and at this time, the drawer 32 can be opened by pressing. Thus, the lock device 20 of the present embodiment does not require an additional manual unlocking mechanism component compared to the prior art.

Preferably, in the process of moving the second object 26 from the closing position R to the opening direction D2 to the predetermined position P relative to the first object 24, the second member 64 is driven by the lock 68 to drive the first member 60, so that the first member 60 moves from the locked state Y2 (shown in fig. 14) to the unlocked state Y1 (shown in fig. 15). For example, in the process of displacing the second object 26 relative to the first object 24 from the closing position R toward the opening direction D2 to the predetermined position P, the fitting 46 drives the slide 86 toward the opening direction D2, so that the second portion 96b of the hook 96 on the slide 86 and the middle portion 78 of the lock 68 abut against each other (as shown in fig. 15), the lock 68 is longitudinally displaced from an initial position (as shown in fig. 14) toward the opening direction D2 to the predetermined position P (as shown in fig. 15) relative to the base 66, and the lock 68 is accordingly interlocked with the first portion 64a of the second member 64, so that the second member 64 pivots an angle toward a third predetermined direction R3 through the second shaft M2, so that the second portion 64b of the second member 64 pushes the first member 60 to move from the locked state Y2 to the unlocked state Y1 (as shown in fig. 15).

Preferably, the first section 64a of the second member 64 extends into a portion of an accommodating space 69 (as shown in fig. 11) of the latch 68, such that the latch 68 can be coupled with the first section 64a of the second member 64 through an inner wall 71 of the accommodating space 69, thereby pivoting the second member 64 toward the third predetermined direction R3.

Preferably, the second sensor 74 is configured to sense whether the second object 26 is at the predetermined position P (as shown in fig. 15, the predetermined position P is only represented by the latch 68 being at the predetermined position P). For example, when the lock 68 is at the predetermined position P, the lock 68 can press against the second elastic sensing portion 74a of the second sensor 74, whereby the lock device 20 can detect that the second object 26 is at the predetermined position P. If the second object 26 (drawer 32) is displaced from the retracted position R to the opening direction D2 to the predetermined position P by another person in the aforementioned manner relative to the first object 24 (cabinet 30) without losing the supply of the electric power 100, the first member 60 returns to the locked state Y2 (as shown in fig. 14) by the second electromagnet B being energized accordingly, once the other person releases the second object 26 (drawer 32) from the predetermined position P, by the signal detected by the second elastic sensing portion 74a of the second sensor 74.

Preferably, when the latch 68 is at the predetermined position P (as shown in fig. 15), the elastic member 70 is configured to accumulate a restoring elastic force for providing the latch 68 to return to the initial position (as shown in fig. 14), so that the latch 68 no longer presses against the second elastic sensing portion 74a of the second sensor 74.

As shown in fig. 16, when the second article 26 (drawer 32) is in the extended position E relative to the first article 24 (cabinet 30) (only the fitting 46 is shown in the extended position E relative to the lock device 20 in fig. 16), the slider 86 is in a biased position W2 relative to the intermediate member 78, at which time the second leg 94 of the slider 86 has been moved away from the longitudinal path 90a of the track 90 of the intermediate member 84 into the curved path 90b of the track 90; during the displacement of the second object 26 (drawer 32) relative to the first object 24 (cabinet 30) from the extended position E toward the retracted direction D1 (only displacement of the fitting 46 relative to the locking device 20 from the extended position E toward the retracted direction D1 is illustrated in fig. 16), a guide portion 106 (e.g., a slope or a cambered surface) of the slider 86 is contacted by the auxiliary portion 52 of the fitting 46, such that the slider 86 is rotated from the biased position W2 to an initial predetermined position W1, and the second portion 96b of the locking hook 96 is accessible from the entrance 80 of the path T of the locking device 68 (as shown in fig. 13) until the fitting 46 is returned to the retracted position R relative to the locking device 20 (as shown in fig. 10).

Fig. 17 is a first operation flow diagram of the lock device 20 according to an embodiment of the present application, which includes the following steps:

step S110: the communication device 102 sets the drawer 32 to be unlocked.

In step S110, the communication device 102 is installed with an Application (App), and the user can send an unlock signal through the App of the communication device 102.

Step S120: the first electromagnet a is energized to place the first member 60 in the unlocked state Y1.

In step S120, when the lock device 20 receives the unlocking signal of the communication device 102, the first electromagnet a is energized to drive the first member 60 to the unlocking state Y1.

Step S130: the drawer 32 can be pressed open.

In this step S130, when the first member 60 is in the unlocked state Y1, the drawer 32 (the second object 26) is allowed to be opened by being pressed from the retracted position R along the retraction direction D1 relative to the cabinet 30 (the first object 24).

Fig. 18 is a second operation flow diagram of the lock device 20 according to an embodiment of the application, which includes the following steps:

step S210: the communication device 102 sets the drawer 32 to be locked.

In step S210, the user may send a lock signal through the application program of the communication device 102.

Step S220: the second electromagnet B is energized to place the first member 60 in the locked state Y2.

In step S220, when the locking device 20 receives the locking signal of the communication device 102, the second electromagnet B is energized to drive the first member 60 to the locked state Y2.

Step S230: it is detected whether the second sensor 74 is normally closed.

In step S230, the lock device 20 may detect whether the second sensor 74 is in a Normally Closed (NC) state, for example, whether the second elastic sensing portion 74a of the second sensor 74 is not pressed. If not, go to step S240: the drawer 32 cannot be pressed open. If yes, go to step S250: the drawer 32 can be pulled out a distance to the predetermined position P, and the second member 64 brings the first member 60 to the unlocked state Y1.

Step S260: it is detected whether the first sensor 72 is in a normally open state.

In step S260, the lock device 20 can detect whether the first sensor 72 is in a Normally Open (NO) state, for example, whether the first elastic sensing portion 72a of the first sensor 72 is pressed, so as to detect whether the second object 26 (or the drawer 32) is in the retracted position R (as shown in fig. 10) relative to the first object 24 (or the cabinet 30). If not, go to step S270: the communication device 102 alerts that the drawer 32 is not fully closed. In step S270, for example, the communication device 102 may send out a sound and/or an electronic message through the application program for the user to know that the drawer 32 is not in the retracted position R. If yes, go to step S220: the second electromagnet B is energized to place the first member 60 in the locked state Y2. In step S220, the first elastic sensing portion 72a of the first sensor 72 is pressed, which indicates that the second object 26 (or the drawer 32) is at the retracted position R relative to the first object 24 (or the cabinet 30) (as shown in fig. 10, the predetermined portion 104 of the slider 86 presses the first elastic sensing portion 72a of the first sensor 72), and at this time, the second electromagnet B is energized accordingly, so that the first member 60 is in the locked state Y2, and the second object 26 (or the drawer 32) cannot be pressed and opened.

It will be appreciated that the lock device 20 of the present embodiment includes the following features:

1. the first member 60 of the lock device 20 can be electrically controlled to be in the locked state Y2 or the unlocked state Y1. When the first member 60 is in the locked state Y2, the second object 26 cannot be opened by being pressed in the folding direction D1 from the folding position R relative to the first object 24; when the first member 60 is in the unlocked state Y1, the second object 26 can be pressed from the retracted position R along the retraction direction D1 relative to the first object 24 to be opened.

2. The second member 64 can drive the first member 60 to move the first member 60 from the locked state Y2 to the unlocked state Y1. Such an operating mechanism may be applied, for example, when the power module 98 ceases to supply power 100 to the control module 62 or associated electronic components are damaged and the first member 60 is in the locked state Y2. Specifically, the user only needs to operate the second object 26 (drawer 32) to move from the retracted position R to the predetermined position P in the opening direction D2 relative to the first object 24 (cabinet 30), and the first member 60 can be driven by the second member 64 to move the first member 60 from the locked state Y2 to the unlocked state Y1, so that, compared to the prior art, the lock device 20 of the present embodiment does not need to add a manual unlocking mechanism.

While the application has been described with reference to the present specific embodiments, it will be appreciated by those skilled in the art that the above embodiments are for illustration only and that various equivalent changes and modifications may be made without departing from the spirit of the application, and therefore, all changes and modifications to the above embodiments shall fall within the scope of the appended claims.
