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 where it can be used to capture the pin of the inner rail. Through the retraction action of the inner rail, the pin of the inner rail pushes the latch receiver to rotate from the first position to a second position, thereby locking the inner rail. In conjunction with this application... Figure 11 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 against the latch receiver, rotating it from the second position to the first position to release the pin of the inner rail. According to this configuration, the inner rail can be released relative to the outer rail, meaning the inner rail can leave the retracted position relative to the outer rail.

[0004] It is worth mentioning that the patent discloses a manual release member 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 member 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. US2019 / 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] For example, patent publication number CN112746774A and patent announcement number TWI702017 also disclose electronic locks. When there is a power outage or no power, manual unlocking requires an external mechanism to apply force to the unlock position, which may be a nylon rope or a set of linkage mechanisms. The external mechanism is placed on the exterior surface of the cabinet and hidden by a design such as a decorative panel, causing problems in terms of both usability and aesthetics.

[0007] 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

[0008] 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.

[0044] like Figure 1 and Figure 2As 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.

[0045] Preferably, a third component 28 is movably mounted between the first component 24 and the second component 26. Here, the first component 24 is taken as a first rail (e.g., a fixed rail), the second component 26 as a second rail (e.g., a movable rail), and the third component 28 as a third rail (e.g., an intermediate rail), but the implementation is not limited to this. The first component 24, the second component 26, and the third component 28 can move longitudinally or linearly relative to each other, and together constitute an undermount slide rail assembly 29.

[0046] 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.

[0047] Preferably, the first object 24 includes an extension 34, and the second object 26 includes a support portion 36.

[0048] 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).

[0049] Preferably, the locking device 20 is mounted to the first object 24. Specifically, 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 detachably 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.

[0050] 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.

[0051] 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 is a protrusion, but the implementation is not limited to this. Since the fitting 46 is mounted to the second object 26, the fitting 46 and the second object 26 can be considered as one unit.

[0052] Preferably, the accessory 46 includes a first pre-determined portion 52, a second pre-determined portion 54, and a space 56 defined between the first pre-determined portion 52 and the second pre-determined portion 54.

[0053] like Figure 5 and Figure 6 As shown, the locking device 20 includes a slider 58, a drive module 60, and a locking tongue 62.

[0054] Preferably, the locking device 20 further includes a base 66, an elastic element 68, a first sensor 70, a second sensor 72, a fixed base 74, and a control circuit board 76, for example.

[0055] The locking device 20, with the mounting feature 40 disposed on the base 66, can be mounted to the first object 24; the slider 58, the drive module 60, the latch 62, the elastic element 68, the first sensor 70, the second sensor 72, the mounting base 74, and the control circuit board 76 are all arranged on the base 66. The mounting base 74 is arranged upright or perpendicular to the base 66, and at least a portion of the control circuit board 76 is arranged on the mounting base 74.

[0056] The drive module 60 is electrically connected to the control circuit board 76. Here, it is taken as an example that the drive module 60 can be electrically connected to the control circuit board 76 through a first electronic wire 77a and a second electronic wire 77b, but the implementation is not limited to this.

[0057] The drive module 60 includes a magnet 78 (e.g., a permanent magnet, but not limited in implementation). Preferably, the drive module 60 is an electromagnet module, and the drive module 60 also includes a housing 80, a metal rod 82 (e.g., an iron core, but not limited in implementation), a coil 84, and a spring 86. The magnet 78 and the coil 84 are arranged within the housing 80. The metal rod 82 is energized by the coil 84 and can extend and retract relative to the housing 80. The spring 86 provides a spring force to the metal rod 82; for example, the spring 86 is disposed on the metal rod 82.

[0058] The slider 58 is connected (e.g., fixed, but not limited to) to the metal rod 82. The latch 62 is movable relative to the slider 58, in which case the latch 62 is movably arranged to the slider 58. For example, the latch 62 is pivotally connected to the slider 58 via a shaft 88, but implementation is not limited to this.

[0059] Preferably, the elastic element 68 can provide elastic force to the latch 62; the first sensor 70 and the second sensor 72 can be electrically connected to the control circuit board 76.

[0060] like Figure 7 As shown, the lock device 20 includes a power module 90, which provides electrical energy 92 to the drive module 60. Preferably, the power module 90 is electrically connected to the control circuit board 76. A communication device 94 can be connected to the lock device 20 wirelessly or via a wired connection to control the drive module 60. The communication device 94 can be, for example, a mobile phone, tablet computer, or smartwatch, but is not limited to any particular device.

[0061] like Figure 8 and Figure 9 As shown, the accessory 46 can be installed onto the aforementioned second object 26 (at... Figure 8 and Figure 9 Only the accessory 46 is shown to represent the second item 26 or drawer 32), and the locking device 20 can be installed on the aforementioned first item 24 (at... Figure 8 and Figure 9 The lock device 20 is shown only to represent the first object 24 or cabinet 30.

[0062] The drive module 60 is used to drive the slider 58. More specifically, the drive module 60 is used to drive the slider 58 to a locked position X1 (e.g., Figure 8 ) and an unlock position x2 (e.g. Figure 9 One of them. Here, since the slider 58 is connected to the metal rod 82, when the power module 90 supplies electrical energy 92 to the drive module 60, causing the coil 84 to receive different power signals (e.g., reverse or forward), the metal rod 82 moves, thus driving the slider 58 to the locked position X1 (e.g., ...). Figure 8 ) or unlock location X2 (e.g. Figure 9 ).

[0063] Preferably, when the metal rod 82 and the slider 58 are in the locked position X1, the spring 86 can provide a spring force to the metal rod 82, so that the metal rod 82 and the slider 58 are held in the locked position X1 (e.g., Figure 8Alternatively, when the metal rod 82 and the slider 58 are in the unlocked position X2, the metal rod 82 can be attracted by the magnetic force of the magnet 78, so that the metal rod 82 and the slider 58 are held in the unlocked position X2 (e.g., Figure 9 ).

[0064] Preferably, the direction of movement (lateral) of the metal rod 82 and the slider 58 is perpendicular to the direction of movement (longitudinal, such as D1 or D2) of the object (e.g., the second object 26).

[0065] When the second object 26 (represented by accessory 46) is in the retracted position R relative to the first object 24 (represented by locking device 20), the drive module 60 can drive the slider 58 to the locked position X1 in a first lateral direction T1, so that the latch 62 can block the second object 26 (e.g., Figure 8 For example, when the slider 58 is in the locked position X1, the latch 62 can partially extend into the space 56 of the accessory 46, so that the latch 62 can block the first predetermined part 52 of the accessory 46 to prevent the second object 26 from moving relative to the first object 24 from the closed position R to an opening direction D1 to the extended position E.

[0066] Alternatively, the drive module 60 can drive the slider 58 to the unlocked position X2 in a second transverse direction T2 opposite to the first transverse direction T1, so that the latch 62 cannot block the second object 26 (e.g., Figure 9 For example, when the slider 58 is in the unlocked position X2, the latch 62 is not inserted into the space 56 of the accessory 46, so that the latch 62 cannot block the first predetermined part 52 of the accessory 46, thereby allowing the second object 26 to move relative to the first object 24 from the retracted position R to the opening direction D1, for example, to the aforementioned extended position E. It is worth mentioning that the second object 26 can also return to the retracted position R relative to the first object 24 from the extended position E to a retracting direction D2.

[0067] Furthermore, the first sensor 70 is used to sense whether the second object 26 (represented by accessory 46, which refers to the second object 26 or the drawer 32) is in the closed position R. Specifically, the first sensor 70 can be used to generate a first signal or a second signal. For example, when the second object 26 is in the closed position R, the second object 26 (represented by accessory 46, which refers to the second object 26 or the drawer 32) can press against a first elastic sensing part 70a of the first sensor 70, causing the first sensor 70 to generate the second signal, indicating that the second object 26 (or drawer 32) is currently in the closed position R (e.g., Figure 8Alternatively, if the second object 26 (represented by accessory 46, which refers to the second object 26 or drawer 32) does not press against the first elastic sensing part 70a of the first sensor 70, the first sensor 70 will generate the first signal, indicating that the second object 26 (or drawer 32) is not in the closed position R at this time, for example, the second object 26 or the drawer 32 is in an open or extended state (e.g., Figure 9 ).

[0068] The second sensor 72 is used to sense whether the slider 58 is in the locked position X1. Specifically, the second sensor 72 can be used to generate a third signal or a fourth signal. For example, when the slider 58 is in the locked position X1, the slider 58 does not press against a second elastic sensing part 72a of the second sensor 72, causing the second sensor 72 to generate the fourth signal, indicating that the slider 58 is currently in the locked position X1 (e.g., ...). Figure 8 Alternatively, the slider 58 presses against the second elastic sensing part 72a of the second sensor 72, and the second sensor 72 generates the third signal, indicating that the slider 58 is currently in the unlocked position X2 (e.g., Figure 9 ).

[0069] like Figure 10 This is a schematic diagram of the first operation flow of a locking device 20 according to an embodiment of the present invention, which includes the following steps:

[0070] Step S110: The communication device sets the drawer status to locked.

[0071] In this step S110, the communication device 94 may have an application (App) installed, and the user can send a lock signal through the application on the communication device 94.

[0072] Step S120: Detect whether the first sensor is the second signal.

[0073] In this step S120, as Figure 8 As shown, the locking device 20 can detect whether the first sensor 70 is in the state of the second signal. For example, the second object 26 (represented by accessory 46 or drawer 32) can press against the first elastic sensing part 70a of the first sensor 70, causing the first sensor 70 to generate the second signal, indicating that the second object 26 (or drawer 32) is in the closed position R relative to the first object 24 (or cabinet 30).

[0074] If so, proceed to step S130: the drive module supplies a first power signal, and the slider moves to the locked position. In this step, when the second object 26 is in the retracted position R relative to the first object 24, and the locking device 20 receives the locking signal from the communication device 94, the drive module 60 drives the slider 58 to the locked position X1 (e.g., Figure 8 As shown), the latch 62 can block the second object 26 (represented by accessory 46, which may also refer to drawer 32). Specifically, the metal bar 82 of the drive module 60 can be driven by the first power signal (e.g., reverse power, but not limited to) provided by the power module 90 on the control circuit board 76 to the coil 84, so that the slider 58 can be in the locked position X1 in response to the movement of the metal bar 82. Figure 8 As shown), the latch 62 is able to block the second object 26 in an initial state S1.

[0075] If not, proceed to step S140: the communication device warns that the drawer is not fully closed. In this step, if the first sensor 70 does not generate the second signal, the communication device 94 can issue an alarm sound and / or electronic message through the application to inform the user that the second item 26 (drawer 32) is not fully in the closed position R.

[0076] Furthermore, after step S130, step S150 can be performed: detecting whether the second sensor is the fourth signal. In this step S150, if... Figure 8 As shown, the locking device 20 can detect whether the second sensor 72 is in the state of the fourth signal. For example, if the slider 58 does not press the second elastic sensing part 72a of the second sensor 72, the second sensor 72 will generate the fourth signal, indicating that the slider 58 is in the locked position X1 at this time.

[0077] If so, proceed to step S160: the drawer cannot be opened. In this step S160, if the second sensor 72 generates the fourth signal and the slider 58 is in the locked position X1, then the second object 26 (drawer 32) cannot move relative to the first object 24 (cabinet 30) from the closed position R to the opening direction D1 (e.g., Figure 8 (As shown).

[0078] If not, proceed to step S170: The communication device issues a system error message. In this step S170, if the second sensor 72 does not generate the fourth signal, it indicates that the slider 58 is not in the locked position X1. The communication device 94 can issue an alarm sound and / or electronic message through the application to inform the user that the slider 58 is not in the locked position X1, which is a system error message.

[0079] like Figure 11This is a schematic diagram of the second operation flow of a locking device 20 according to an embodiment of the present invention, which includes the following steps:

[0080] Step S210: The communication device sets the drawer status to unlock.

[0081] In this step S210, the user can send an unlock signal through the application on the communication device 94.

[0082] Step S220: The drive module receives a second power signal, and the slider moves to the unlock position. In this step, when the lock device 20 receives the unlock signal from the communication device 94, the drive module 60 drives the slider 58 to the unlock position X2, so that the bolt 62 cannot block the second object 26 (represented by accessory 46, which may also refer to drawer 32). Specifically, the metal rod 82 of the drive module 60 is driven by the second power signal (e.g., forward power, but not limited to) provided by the power module 90 on the control circuit board 76 to the coil 84, so that the slider 58 responds to the movement of the metal rod 82 and moves to the unlock position X2 (e.g., forward power, but not limited to forward power). Figure 9 As shown), this prevents the latch 62 from blocking the second object 26 in the initial state S1.

[0083] Step S230: Detect whether the second sensor is a third signal. In this step S230, as follows... Figure 9 As shown, the locking device 20 can detect whether the second sensor 72 is in the state of the third signal. For example, by pressing the second elastic sensing part 72a of the second sensor 72 with the slider 58, the second sensor 72 generates the third signal, indicating that the slider 58 is currently in the unlocked position X2.

[0084] If so, proceed to step S240: the drawer can be opened. In this step S240, if the second sensor 72 generates the third signal and the slider 58 is in the unlocked position X2, then the second object 26 (drawer 32) can be displaced relative to the first object 24 (cabinet 30) from the closed position R towards the opening direction D1 (e.g., Figure 9 (As shown).

[0085] If not, proceed to step S250: The communication device issues a system error message. In this step S250, if the second sensor 72 does not generate the third signal, it indicates that the slider 58 is not in the unlocked position X2. The communication device 94 can issue an alarm sound and / or electronic message through the application to inform the user that the slider 58 is not in the unlocked position X2, which is a system error message.

[0086] like Figure 12 and Figure 13As shown, when the drive module 60 cannot be driven by the power module 90, for example, if the power module 90 is damaged, has no power, or has insufficient power to drive the drive module 60, and the slider 58 is in the locked position X1, it can be moved from the closed position R (e.g., by means of the second object 26, referred to as accessory 46 or drawer 32) through the second object 26. Figure 12 Displace in the opening direction D1, for example, displace a distance to a predetermined position Y (e.g.) Figure 13 The second object 26 can move the latch 62 from the initial state S1 to a non-initial state S2. For example, the first predetermined part 52 of the accessory 46 contacts the latch 62, causing the latch 62 to rotate from the initial state S1 to the non-initial state S2 by an angle in a predetermined direction K, thereby actuating (e.g., pushing) the slider 58 (and the metal rod 82) from the locked position X1 (e.g.) Figure 12 Move to the second horizontal T2 position X2 (e.g.) Figure 13 When the locking tongue 62 is in the non-initial state S2, the elastic element 68 is in a state of accumulating elastic force (e.g., Figure 13 ).

[0087] Preferably, the space 56 of the accessory 46 has an abutment 96 (e.g., a groove, but not limited) adjacent to the first predetermined portion 52. The abutment 96 can be used to provide locking during the pivoting of the latch 62 from the initial state S1 to the non-initial state S2, which helps the latch 62 to move the slider 58 and the metal rod 82 from the locked position X1 (e.g., Figure 12 Move to the second horizontal T2 position X2 (e.g.) Figure 13 This also helps the slider 58 and the metal rod 82 to easily overcome the elastic force of the spring 86 during the second transverse movement T2.

[0088] Preferably, when the slider 58 is in the unlocked position X2, the slider 58 can be held in the unlocked position X2 by the magnet 78 of the drive module 60. For example, the slider 58 can be held in the unlocked position X2 by the magnetic attraction of the metal rod 82 by the magnet 78. Wherein, since the latch 62 pivots to abut against a guide portion 98 of the slider 58 (e.g., an inclined surface, but not limited), the force of the second object 26 (only the accessory 46 refers to the second object 26 or the drawer 32) displacing in the opening direction D1 is converted and restricted by the slider 58 (e.g., Figure 13 This prevents the second object 26 (referred only to as accessory 46, or drawer 32) from continuing to open in the first direction D1.

[0089] like Figure 13 and Figure 14As shown, because the second object 26 (referred only to as accessory 46, or drawer 32) cannot continue to open in the first direction D1 (e.g.) Figure 13 The second object 26 (referred only to as accessory 46 or drawer 32) can only be displaced in the closing direction D2 (e.g., Figure 14 Furthermore, when the slider 58 remains in the unlocked position X2, and the second object 26 is in the predetermined position Y (e.g., Figure 13 Displaced in the direction of convergence D2 (e.g.) Figure 14 When the latch 62 responds to the elastic member 68 releasing the elastic force, it can return from the non-initial state S2 to the initial state S1. At this time, the latch 62 will not obstruct the first predetermined part 52 of the accessory 46 (e.g., Figure 14 This allows the second object 26 (referred only to the accessory 46 as the second object 26 or the drawer 32) to move in the opening direction D1 to the aforementioned extended position E.

[0090] Based on the above description, it can be seen that the improved efficacy and advantages of the present invention are as follows: when the power supply to the lock device 20 is lost or the relevant electronic components are damaged, without the need for an external manual unlocking mechanism, the user only needs to pull the second object 26 (the drawer 32) a distance in the opening direction D1 by hand, so that the slider 58 can move from the locked position X1 to the unlocked position X2, thereby achieving manual unlocking, which is convenient to use.

[0091] Although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are merely illustrative of the invention, and various equivalent changes and modifications can be made without departing from the spirit of the invention. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the invention will fall within the scope of the claims of this application.
