Description

Technical Field

[0001] This invention relates to a lock, and more particularly to a lock device suitable for two objects that can move relative to each other. Background Technology

[0002] Generally, drawer slide assemblies are used in home, office, or electronic equipment rack systems. The slide assembly includes a first rail and a second rail, respectively mounted on a first object and a second object, such as a cabinet and a drawer, allowing the drawer to be opened or closed relative to the first rail and / or the cabinet via the second rail. Depending on the requirements, sometimes the market or users do not want the second rail (second object) to be arbitrarily operated from a predetermined position relative to the first rail (first object) and moved away from that predetermined position.

[0003] For example, US Patent Publication No. 8,328,299B2 discloses a drawer slide and locking mechanism. The locking mechanism is an electronic lock. [The following sentence appears to be incomplete and possibly refers to a different topic:] From this case... Figure 1 It is understood that the drawer slide includes an outer rail and an inner rail. The inner rail can be in a retracted position relative to the outer rail. The rear end of the inner rail is equipped with a pin. On the other hand, the locking mechanism includes a latch receiver, a lever arm, and a motor. As in this case... Figure 1 and Figure 2 As shown, the latch receiver can be in a first position, and in this first position, the latch receiver is in a state that can be used to capture the pin of the inner rail, in accordance with the present invention. Figure 3 As shown, once the motor receives an electronic control signal, it can drive the lever arm to rotate, causing the top of the lever arm to move and push the latch receiver from the first position to the second position, thereby locking the pin of the inner rail. According to this configuration, the inner rail can be locked relative to the outer rail in the retracted position, meaning the inner rail cannot leave the retracted position relative to the outer rail.

[0004] It is worth mentioning that the patent also discloses a manual release mechanism that extends or is exposed outside a housing of the locking mechanism. When the power supply to the motor is lost or the electronic components are damaged, the user can pull the manual release mechanism to move the lever arm to an unlocked position, so that the latch receiver can return to the first position and unlock the pin of the inner rail, thereby allowing the inner rail to leave the closed position.

[0005] For example, US Patent Publication No. 2019 / 0063113A1 discloses an electronic lock in which a motor controls a bolt to lock or unlock it. The case also includes an additional pull-cord manual unlocking mechanism for the user to pull, thereby driving the bolt from locked to unlocked.

[0006] Due to varying market demands and structural operating methods, it is sometimes undesirable to implement the lock function in the manner described in the aforementioned patent. Furthermore, as mentioned above, this type of electronic lock requires a separate manual unlocking mechanism (such as the aforementioned manual release mechanism) to activate the unlocking mechanism using external force when power is lost or electronic components malfunction. Therefore, developing a different product becomes an issue that cannot be ignored. Summary of the Invention

[0007] The purpose of this invention is to provide a locking device that can be applied to a first object and a second object that are relatively movable.

[0008] According to one aspect of the present invention, a locking device is applicable to a first object and a second object that are relatively movable. The locking device includes a first member and a second member. The first member is movably in one of a locked state and an unlocked state; wherein, the second member can drive the first member to move from the locked state to the unlocked state in response to the second object displacing relative to the first object from a closed position to an open direction to a predetermined position.

[0009] According to another aspect of the invention, a locking device is suitable for a piece of furniture, the furniture comprising a first object and a second object that are movable relative to each other, and a driving device for providing the second object to be opened by pressing it relative to the first object in a closed position along a closing direction. The locking device includes a first component and a control module. The control module is used to drive the first component to one of a locked state and an unlocked state; wherein, when the first component is in the locked state, the second object cannot be opened by pressing it relative to the first object from the closed position along the closing direction; wherein, when the first component is in the unlocked state, the second object is allowed to be opened by pressing it relative to the first object from the closed position along the closing direction.

[0010] According to another aspect of the present invention, a locking device is suitable for use with a communication device. The locking device includes a base, a first component, and a control module. The first component is movably mounted on the base; the control module includes a first electromagnet and a second electromagnet; wherein, when receiving an unlock signal from the communication device, the control module moves the first component to an unlocked state via the first electromagnet; wherein, when receiving a lock signal from the communication device, the control module moves the first component to a locked state via the second electromagnet.

[0030] like Figure 1 and Figure 2 As shown, a locking device 20 of one embodiment of the present invention, such as a smart lock device or an electronic lock, is suitable for a piece of furniture 22, which includes a first object 24 and a second object 26 that are movable relative to each other.

[0031] 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 as a second rail (e.g., a movable rail), and the third object 28 as a third rail (e.g., an intermediate rail), but the implementation is not limited to this. The first object 24, the second object 26, and the third object 28 can be longitudinally displaced relative to each other and together constitute a slide rail assembly 23.

[0032] Preferably, the first object 24 is arranged (e.g., fixed) in a cabinet 30, and the second object 26 is used to carry a drawer 32. The drawer 32 can be in an extended position E relative to the first object 24 (or cabinet 30) through the second object 26.

[0033] Preferably, the first object 24 includes an extension 34, and the second object 26 includes a support portion 36.

[0034] like Figure 3 and Figure 4 As shown, the second object 26 can be in a retracted position R relative to the first object 24. In this retracted position R, the position of the supporting portion 36 of the second object 26 substantially corresponds to the extension portion 34 of the first object 24 (e.g., ...). Figure 3 (As shown).

[0035] Preferably, the locking device 20 is detachably mounted to the first object 24. For example, the locking device 20 has a mounting feature 40, and one side wall 35 of the extension 34 of the first object 24 has a mounting structure 42 that can be mounted to the mounting feature 40. Here, 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, but the implementation is not limited to this.

[0036] Preferably, the locking device 20 has a housing 44 that can be used to cover most of the relevant parts of the locking device 20, providing protection.

[0037] Preferably, the furniture 22 further includes a fitting 46, which is detachably mounted to the support portion 36 of the second object 26. For example, the fitting 46 has a connecting feature 48, and the support portion 36 of the second object 26 has a connecting structure 50 that can be installed with the connecting feature 48. Here, one of the connecting feature 48 and the connecting structure 50 is a slot, and the other of the connecting feature 48 and the connecting structure 50 is a protrusion, but the implementation is not limited to this.

[0038] Preferably, the accessory 46 includes an auxiliary part 52 (such as... Figure 4 As shown, the auxiliary part 52 can be used in conjunction with the locking device 20. The auxiliary part 52 is, for example, a protrusion, but is not limited in implementation.

[0039] like Figure 5 As shown, when the second object 26 is configured to be push-open relative to the first object 24, and the second object 26 is in the closed position R relative to the first object 24, a gap G is formed between the drawer 32 and the cabinet 30. This gap G allows the user to press the drawer 32 to move relative to the cabinet 30, so that the drawer 32 can be opened relative to the cabinet 30.

[0040] Furthermore, the furniture 22 includes a drive mechanism 54 for providing the second object 26 to be opened relative to the first object 24 in the closed position R by pressing it along a closing direction D1. Specifically, the drive mechanism 54 is disposed on the second object 26, and the drive mechanism 54 includes an elastic member 56 and a locking mechanism 58. The elastic member 56 provides a spring force F, and the locking mechanism 58 can be operated in a locked state (e.g., Figure 5 ) and a detent state (such as Figure 6One of the locking mechanisms. When the locking mechanism 58 is in the locked state, the elastic member 56 stores the elastic force F. When the locking mechanism 58 is in the unlocked state, the elastic member 56 releases the elastic force F. Specifically, when the drawer 32 is in the closed position R relative to the cabinet 30, and the distance G is maintained between the drawer 32 and the cabinet 30, the locking mechanism 58 is in the locked state.

[0041] like Figure 6 and Figure 7 As shown, when the user applies a pressing force K along the closing direction D1 to the drawer 32 (or the second object 26), causing the drawer 32 (or the second object 26) to reach an overpressure position X, the locking mechanism 58 of the drive device 54 is operated from the aforementioned locked state to the unlocked state. When the pressing force K is stopped, the elastic member 56 of the drive device 54 immediately releases the spring force F. Through the spring force F, the drawer 32 relative to the cabinet 30 is opened from the overpressure position X and displaced along an opening direction D2. At this time, the drawer 32 forms an extension distance L relative to the cabinet 30. This is the so-called press-to-open function. For example, the drawer 32 can now be in the extended position E relative to the cabinet 30. The direction of the spring force F of the drive device 54 is opposite to the closing direction D1.

[0042] like Figure 8 and Figure 9 As shown, the locking device 20 includes a first component 60 and a control module 62. Here, it is taken as an example that the locking device 20 also includes a second component 64.

[0043] Preferably, the locking device 20 further includes a base 66, on which the control module 62, the first component 60, and the second component 64 are all arranged. The base 66 has the mounting feature 40; the control module 62 includes at least one electromagnet, for example, a first electromagnet A and a second electromagnet B, but the number is not limited in practice; the first component 60 and the second component 64 are, for example, swing arms, and both are movably mounted on the base 66. For example, the first component 60 and the second component 64 can be pivotally connected to the base 66 via a first shaft M1 and a second shaft M2, respectively. The first component 60 has a first segment 60a and a second segment 60b, the first shaft M1 is located between the first segment 60a and the second segment 60b, and the first segment 60a is provided with a metal part 67 (e.g., Figure 9 As shown), the metal part 67 is located in a space S between the first electromagnet A and the second electromagnet B; on the other hand, the second component 64 has a first segment 64a and a second segment 64b, and the second shaft M2 is located between the first segment 64a and the second segment 64b of the second component 64.

[0044] Preferably, the locking device 20 further includes a latch 68, an elastic element 70, a first sensor 72, and a second sensor 74 arranged on the base 66. The latch 68 is longitudinally movable relative to the base 66 and includes at least one wall, such as a first extension wall 76a and a second extension wall 76b. Preferably, it also includes an intermediate portion 78 located 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, which has an entrance 80 and an exit 82 (e.g., ...). Figure 8 As shown, preferably, the middle portion 78 is a protrusion with a heart-shaped outline, but the implementation is not limited; the elastic member 70 provides elasticity to the latch 68; the first sensor 72 and the second sensor 74 can be electronic switches, such as proximity switches or micro switches, but the implementation is not limited. Furthermore, the first sensor 72 has a first elastic sensing portion 72a, and the second sensor 74 has a second elastic sensing portion 74a.

[0045] Preferably, the locking device 20 further includes an intermediate member 84 and a slider 86. The intermediate member 84 is arranged on the base 66, for example, the intermediate member 84 is fixed to the base 66 via at least one fastener 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 connecting the bottom and the top. The predetermined space 88 is, 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 can be used to support the slider 86. Preferably, the top of the intermediate member 84 has a track 90; the slider 86 can move along the track 90 of the intermediate member 84. Preferably, the track 90 includes a longitudinal path 90a and a bent path 90b connecting the longitudinal path 90a (e.g., ...). Figure 8 (As shown). Preferably, the slider 86 includes a retaining portion 92, a first foot 93, and a second foot 94. The retaining portion 92 is used in conjunction with the auxiliary portion 52 of the aforementioned accessory 46, and the first foot 93 and the second foot 94 are used in conjunction with the track 90 of the intermediate component 84. Preferably, a locking hook 96 is movably mounted on the slider 86, and the locking hook 96 includes a first part 96a and a second part 96b. The first part 96a extends into a portion of a mounting space 95 of the slider 86 (e.g., ...). Figure 9 As shown), and the second part 96b passes through the predetermined space 88 of the intermediate part 84 and can be used in conjunction with the path T of the latch 68 (as shown). Figure 8 (As shown).

[0046] like Figure 10 and Figure 11 As shown, since the locking device 20 can be installed to the first object 24 via the mounting feature 40, and the accessory 46 is installed to the second object 26, when the second object 26 (drawer 32) is in the closed position R relative to the first object 24 (cabinet 30), it can also be considered that the accessory 46 is in the closed position R relative to the locking device 20. When the accessory 46 is in the closed position R relative to the locking device 20, the latching portion 92 of the slider 86 can hook onto the auxiliary portion 52 of the accessory 46.

[0047] like Figure 12 As shown, the lock device 20 also includes a power module 98, which can provide electrical energy 100 to the control module 62. A communication device 102 can be connected to the lock device 20 wirelessly or via a wired connection to control the control module 62. The communication device 102 can be, for example, a mobile phone, tablet, or smartwatch, but is not limited to any particular device.

[0048] like Figure 13 and Figure 14 As shown, the first component 60 is movably in an unlocked state Y1 (e.g., Figure 13 ) and a locked state Y2 (such as Figure 14 One of them.

[0049] Preferably, the control module 62 is used to drive the first component 60 to be in the unlocked state Y1 or the locked state Y2.

[0050] Better, such as Figure 13 As shown, when the locking device 20 receives an unlocking signal from the communication device 102, the control module 62 is energized via the first electromagnet A to drive the first component 60 to the unlocked state Y1. Specifically, the first electromagnet A attracts the metal part 67 on the first segment 60a of the first component 60, causing the first component 60 to pivot at an angle in a first predetermined direction R1 via the first shaft M1, thereby ensuring that the second segment 60b of the first component 60 is not obstructed in the path T of the latch 68.

[0051] Better, such as Figure 14 As shown, when the locking device 20 receives a locking signal from the communication device 102, the control module 62 is energized via the second electromagnet B to drive the first component 60 to the locked state Y2. Specifically, the second electromagnet B attracts the metal part 67 on the first segment 60a of the first component 60, causing the first component 60 to pivot at an angle in a second predetermined direction R2 via the first shaft M1, thereby blocking the second segment 60b of the first component 60 in the path T of the latch 68. The second predetermined direction R2 is opposite to the first predetermined direction R1.

[0052] like Figure 10 and Figure 13 As shown, when the first component 60 is in the unlocked state Y1 (e.g.) Figure 13 The second object 26 (because the accessory 46 is installed to the second object 26, Figure 10 Only the accessory 46 is shown (representing the second object 26) allows relative to the first object 24 (since the locking device 20 is installed to the first object 24), Figure 10 The lock device 20 is shown as representing the first object 24) being pressed open from the closed position R along the closing direction D1.

[0053] Specifically, when the first component 60 is in the unlocked state Y1, the second segment 60b of the first component 60 does not obstruct the path T of the latch 68 (e.g., Figure 13 When the accessory 46 is in the closed position R relative to the locking device 20, the latching part 92 of the slider 86 can hook the auxiliary part 52 of the accessory 46. Because the latching part 92 of the slider 86 hooks the auxiliary part 52 of the accessory 46, the second item 26 (drawer 32) can move relative to the first item 24 (cabinet 30) from the closed position R to the closing direction D1 through the accessory 46, in conjunction with the slider 86. During this process, the second segment 60b of the first component 60 will not obstruct the path T of the latch 68, allowing the second part 96b of the latch 96 to move from a corresponding closed position R' along the path T (e.g., ...). Figure 13 As shown), until the second object 26 (drawer 32) moves in the closing direction D1 to the overpressure position X, the second part 96b of the locking hook 96 on the slider 86 is at a corresponding overpressure position X' on the path T, at which point the above-mentioned press-to-open function can be activated (this part can be referred to in conjunction with the above). Figure 6 This causes the second component 26 (drawer 32) to be opened relative to the first component 24 (cabinet 30) from the overpressure position X and displaced along the opening direction D2. During this process, the second part 96b of the locking hook 96 on the slider 86 moves along the path T and can leave the path T from the exit 82 of the path T. Therefore, when the first component 60 is in the unlocked state Y1 and the second component 26 (drawer 32) is in the closed position R, the user is allowed to open the second component 26 (drawer 32) by pressing.

[0054] like Figure 10 and Figure 14 As shown, when the first component 60 is in the locked state Y2 (e.g.) Figure 14 The second object 26 cannot be opened by pressing it relative to the first object 24 from the closed position R along the closing direction D1.

[0055] Specifically, when the first component 60 is in the locked state Y2, the second segment 60b of the first component 60, which blocks the path T of the latch 68, will thus block the second part 96b of the hook 96, preventing the second item 26 (drawer 32) from moving relative to the first item 24 (cabinet 30) in the closing direction D1 to the overpressure position X (that is, the second part 96b of the hook 96 on the slider 86 cannot move from the corresponding closing position R' to the corresponding overpressure position X' of the path T). Therefore, the press-to-open function cannot be activated. Thus, when the first component 60 is in the locked state Y2 and the second item 26 (drawer 32) is in the closed position R, the user cannot open the second item 26 (drawer 32) by pressing.

[0056] Preferably, the first sensor 72 is used to sense whether the second object 26 is in the folded position R (e.g., ...). Figure 10 As shown, since the accessory 46 is installed onto the second object 26, Figure 10 Only the accessory 46 is shown to represent the second object 26, and the first component 60 is thus controlled to be in the locked state Y2 (e.g., Figure 14 (As shown). For example, when the second object 26 (the accessory 46) is in the retracted position R relative to the first object 24 (the locking device 20), the first elastic sensing part 72a of the first sensor 72 can be pressed by a predetermined part 104 of the slider 86, thereby sensing that the second object 26 (the accessory 46) is in the retracted position R (as shown). Figure 10 As shown), the second electromagnet B is energized, causing the first component 60 to be in a locked state Y2 (as shown). Figure 14 (As shown).

[0057] like Figure 14 and Figure 15 As shown, the second component 64 responds to the second object 26 (drawer 32) relative to the first object 24 (cabinet 30) from the closed position R (this part can cooperate). Figure 10 ) Displace in the opening direction D2 to a predetermined position P (e.g. Figure 15 (As shown) and can drive the first component 60, causing the first component 60 to move from the locked state Y2 (as shown) Figure 14 (As shown) The activity is in the unlocked state Y1 (e.g.) Figure 15 (As shown).

[0058] For example, when the power supply 100 is lost (e.g., the power module 98 loses power or unexpectedly stops supplying power 100 to the control module 62) or related electronic components are damaged, and the first component 60 is in the locked state Y2 (e.g.) Figure 14As shown), the second component 64 can respond to the second object 26 (drawer 32) relative to the first object 24 (cabinet 30) by moving from the closed position R to the opening direction D2 to the predetermined position P, thereby driving the first component 60 (as shown). Figure 15 As shown), this causes the first component 60 to be released from the locked state Y2 (as shown). Figure 14 (As shown) The activity is in the unlocked state Y1 (e.g.) Figure 15 (As shown). In other words, the user only needs to move the second object 26 (drawer 32) relative to the first object 24 (cabinet 30) from the closed position R to the opening direction D2 by a predetermined distance to the predetermined position P. This allows the second component 64 to drive the first component 60, moving it from the locked state Y2 to the unlocked state Y1. At this point, the drawer 32 can be opened by pressing. Therefore, compared to the prior art, the lock device 20 of this embodiment does not require an external manual unlocking mechanism component.

[0059] Preferably, during the process of the second object 26 moving relative to the first object 24 from the closed position R to the opening direction D2 to the predetermined position P, the second component 64 can be driven by the latch 68 to drive the first component 60, so that the first component 60 moves from the locked state Y2 (e.g., Figure 14 (As shown) The activity is in the unlocked state Y1 (e.g.) Figure 15 (As shown). For example, during the process of the second object 26 moving relative to the first object 24 from the closed position R to the opening direction D2 to the predetermined position P, the accessory 46 drives the slider 86 in the opening direction D2, causing the second part 96b of the locking hook 96 on the slider 86 to abut against the middle part 78 of the latch 68 (as shown). Figure 15 As shown), the latch 68 is positioned relative to the base 66 from an initial position (as shown). Figure 14 As shown, the device is longitudinally displaced in the opening direction D2 to the predetermined position P (e.g., ...). Figure 15 As shown), and the latch 68 thereby actuates the first segment 64a of the second component 64, causing the second component 64 to pivot at an angle in a third predetermined direction R3 via the second axis M2, so that the second segment 64b of the second component 64 pushes the first component 60 from the locked state Y2 to the unlocked state Y1 (as shown). Figure 15 (As shown).

[0060] Preferably, the first segment 64a of the second member 64 extends into a portion of a receiving space 69 of the latch 68 (e.g., Figure 11 As shown), the latch 68 can be linked to the first segment 64a of the second member 64 through an inner wall 71 of the receiving space 69, thereby pivoting the second member 64 in the third predetermined direction R3.

[0061] Preferably, the second sensor 74 is used to sense whether the second object 26 is at the predetermined position P (e.g., ...). Figure 15 As shown, the second object 26 being in the predetermined position P is represented by the latch 68 being in that predetermined position P. For example, when the latch 68 is in the predetermined position P, the latch 68 can press the second elastic sensing part 74a of the second sensor 74, thereby the locking device 20 can detect that the second object 26 is in the predetermined position P. If, without losing the power supply 100, someone else uses the aforementioned method to move the second object 26 (drawer 32) relative to the first object 24 (cabinet 30) from the closed position R to the opening direction D2 by a predetermined distance to the predetermined position P, then once the other party releases the second object 26 (drawer 32) from the predetermined position P, the signal detected by the second elastic sensing part 74a of the second sensor 74 will energize the second electromagnet B, causing the first component 60 to return to the locked state Y2 (as shown). Figure 14 (As shown).

[0062] Preferably, when the latch 68 is in the predetermined position P (e.g. Figure 15 As shown), the elastic element 70 is in a state of accumulating a restoring force, which is used to provide the latch 68 back to the initial position (as shown). Figure 14 As shown), the latch 68 no longer presses against the second elastic sensing part 74a of the second sensor 74.

[0063] like Figure 16 As shown, when the second item 26 (drawer 32) is in the extended position E relative to the first item 24 (cabinet 30) ( Figure 16 (Only the accessory 46 is shown in the extended position E relative to the locking device 20 for illustration).
