Description

Technical Field

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

[0002] For example, Chinese Patent Publication No. CN 105496046B discloses a slide rail locking mechanism, which uses an electromagnet to connect one end of a pressing piece. The other end of the pressing piece is located above a pressing self-locking mechanism with an intermittent locking function. A locking tongue is located below the pressing self-locking mechanism. The electromagnet can drive the locking tongue through the pressing piece to lock the slide rail.

[0003] The sliding rail locking mechanism disclosed in this patent case has an overly complex structure, requiring many components such as an electromagnet (including an iron core and a spring), a pressing plate, a self-locking mechanism, and a locking tongue to achieve the function of locking.

[0004] As market demands vary, sometimes it's undesirable to implement lock functionality in the manner described in the aforementioned patents. Therefore, developing a different product becomes an issue that cannot be ignored. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic lock that can be applied to a first object and a second object that are relatively movable.

[0006] According to one aspect of the present invention, an electronic lock is applicable to a first object and a second object that are relatively movable. The electronic lock includes a control circuit module and an electromagnetic mechanism. The electromagnetic mechanism is electrically connected to the control circuit module and includes a coil, a driving member, and a magnet. The driving member can be driven to one of a first position and a second position depending on the control circuit module energizing the coil; wherein, when the second object is in a predetermined position relative to the first object, the driving member being in the first position prevents the second object from leaving the predetermined position; wherein, when the second object is in the predetermined position relative to the first object, the driving member being in the second position allows the second object to leave the predetermined position; wherein, when the coil is not energized by the control circuit module, the magnet allows the driving member to remain in one of the first position and the second position.

[0007] Another object of the present invention is to provide an electronic lock in which a driving element of the electronic lock can be kept in a certain position by means of a magnet when the driving element is not driven by a control circuit module.

[0008] According to another aspect of the present invention, an electronic lock includes a control circuit module and an electromagnetic mechanism. The electromagnetic mechanism is electrically connected to the control circuit module and includes a driving member and a magnet. The driving member can be driven by the control circuit module to one of a first position and a second position; wherein, when the driving member is not driven by the control circuit module, the magnet enables the driving member to remain in one of the first position and the second position; wherein, the electronic lock further includes a manual unlocking mechanism; when the driving member is not driven by the control circuit module and is in the first position, the manual unlocking mechanism can move the driving member from the first position to the second position.

[0027] 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.

[0028] 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.

[0029] Preferably, the first object 24 includes an extension 34, and the second object 26 includes a support portion 36.

[0030] like Figure 3 and Figure 4 As shown, the second object 26 can be in a predetermined position R relative to the first object 24, such as a folded position. In this folded position, 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).

[0031] Preferably, the electronic lock 20 is detachably mounted to the first object 24. For example, the electronic lock 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.

[0032] Preferably, the electronic lock 20 has a housing 44 that can be used to cover most of the relevant parts of the electronic lock 20, providing protection.

[0033] 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.

[0034] 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 electronic lock 20. The auxiliary part 52 may be, for example, a hole or a slot, but is not limited in implementation.

[0035] like Figure 5 and Figure 6 The electronic lock 20 is illustrated, but the aforementioned housing 44 is omitted. Furthermore, the electronic lock 20 includes a control circuit module 54 and an electromagnetic mechanism 56. Preferably, the electronic lock 20 also includes a base 58, a manual unlocking mechanism 60, and a sensor 62, for example.

[0036] The electromagnetic mechanism 56 is electrically connected to the control circuit module 54, and the electromagnetic mechanism 56 includes a drive element 64 and a magnet 66. Preferably, the electromagnetic mechanism 56 also includes a coil 68 and an elastic element 70.

[0037] Preferably, the control circuit module 54, the electromagnetic mechanism 56, the manual unlocking mechanism 60, and the sensor 62 are all arranged on the base 58. The base 58 has the mounting feature 40; the control circuit module 54 is connected to a fixing part 72 on the base 58 through at least one connector 71.

[0038] Preferably, the electromagnetic mechanism 56 is electrically connected to the control circuit module 54 through at least one transmission unit 74. The at least one transmission unit 74 may be, for example, a first wire (cable) and a second wire (cable), but the implementation is not limited to this.

[0039] Preferably, the electromagnetic mechanism 56 further includes a receiving member 76, in which the coil 68 and the magnet 66 are disposed within a space S of the receiving member 76, and the driving member 64 extends partially out of the space S from within the space S (e.g., Figure 5 (As shown).

[0040] Preferably, the magnet is a permanent magnet.

[0041] Preferably, the drive member 64 includes a drive portion 78 and a latch portion 80. The drive portion 78 is made of metal; here, an iron core is used as an example, but the implementation is not limited. The latch portion 80 is connected to (e.g., fixedly attached to) the drive portion 78, so that the latch portion 80 and the drive portion 78 can be considered as one unit, and the latch portion 80 has an extension 80a. In other alternative embodiments, the latch portion 80 and the drive portion 78 can be integrated together; therefore, the implementation is not limited.

[0042] Preferably, the elastic member 70 is sleeved on the driving part 78 of the driving member 64, and the elastic member 70 is arranged between the receiving member 76 and the locking tongue part 80.

[0043] Preferably, the electromagnetic mechanism 56 further includes an auxiliary seat 82, which is connected to the base 58 via at least one connecting member 83; the latch 80 of the drive member 64 can pass through an opening H of the auxiliary seat 82, and the auxiliary seat 82 is used to provide a position for the drive member 64 when it is in the first position P1 (see...). Figure 9 ), restricting the second object 26 from leaving the predetermined position R.

[0044] like Figure 7 The electronic lock 20 is shown, but the aforementioned housing 44, control circuit module 54, and electromagnetic mechanism 56 and other related components are omitted.

[0045] The manual unlocking mechanism 60 includes a first component 84 and a second component 86. The first component 84 is movably mounted on the base 58, for example, by pivoting it to the base 58 via a shaft 88. An auxiliary elastic member 90 provides elastic force to the first component 84, allowing it to remain in an initial state S1. Conversely, the second component 86 is movably mounted on the base 58, for example, by displacing it relative to the base 58 via a retaining feature 92 on the base 58. The retaining feature 92 is, for example, an extended channel, allowing the second component 86 to displace linearly relative to the base 58. The direction of this linear displacement of the second component 86 is substantially perpendicular to the direction of longitudinal displacement between the second object 26 and the first object 24 relative to each other.

[0046] Preferably, the first component 84 and the second component 86 are movable relative to each other through a first predetermined feature 94 and a second predetermined feature 96. For example, one of the first predetermined feature 94 and the second predetermined feature 96 is a protrusion, and the other of the first predetermined feature 94 and the second predetermined feature 96 is an elongated hole (or an elongated slot), through which the protrusion passes, but the implementation is not limited (e.g. Figure 7 (As shown).

[0047] Preferably, a corresponding segment 86a of the second member 86 is adjacent to the extension segment 80a of the latch portion 80 of the drive member 64 (e.g., Figure 5 (As shown).

[0048] Preferably, the electronic lock 20 further includes a slider 98 and an elastic feature 100 disposed on the base 58. The elastic feature 100 provides elastic force to the slider 98, holding the slider 98 in a first state W1. The slider 98 includes a guide portion 102 (e.g., a bevel or arc surface), and the sensor 62 is used in conjunction with the slider 98 (e.g., ...). Figure 7 (As shown). Preferably, the sensor 62 is electrically connected to the control circuit module 54 described above.

[0049] like Figure 8 As shown, the electronic lock 20 is used in conjunction with a communication device 104, and the control circuit module 54 is electrically connected to the electromagnetic mechanism 56. The communication device 104 can communicate with the electronic lock 20 wirelessly or via a wired connection. The communication device 104 can be, for example, a mobile phone, tablet, or smartwatch, but is not limited to any particular device.

[0050] like Figure 9 As shown, the drive unit 64 can be driven by the control circuit module 54 to be in a first position P1 (e.g., Figure 9 (as shown) or a second position P2 (this part can be used in conjunction with) Figure 11(As shown). For example, the drive unit 64 can be driven to the first position P1 or the second position P2 depending on the coil 68 being energized by the control circuit module 54. Wherein, as... Figure 9 As shown, when the second object 26 ( Figure 9 The image only shows accessory 46 representing the second object 26) relative to the first object 24. Figure 9 The diagram only shows that when the electronic lock 20 represents the first object 24) is in the predetermined position R (e.g., the closed position), the drive member 64 is in the first position P1, which can prevent the second object 26 from leaving the predetermined position R.

[0051] Specifically, when the second object 26 is in the predetermined position R and the drive member 64 is in the first position P1 (e.g., the locked position), the latch 80 of the drive member 64 extends into the auxiliary part 52 of the accessory 46 (e.g., a hole or slot), and the latch 80 is blocked by a first blocking feature 53a (or a second blocking feature 53b) of the auxiliary part 52, which can prevent the second object 26 from leaving the predetermined position R relative to the first object 24 in an opening direction D1 or (a closing direction D2).

[0052] Preferably, the drive unit 64 can be in the first position P1 according to a first power signal provided by the control circuit module 54. For example, the drive unit 64 can be driven to the first position P1 according to the first power signal provided by the control circuit module 54 to the coil 68. Furthermore, the control circuit module 54 can provide the first power signal (e.g., reverse power, but not limited to) to the coil 68 through at least one transmission unit 74, so that the drive unit 64 is driven to the first position P1 accordingly.

[0053] Preferably, when the drive element 64 is not driven by the control circuit module 54, the elastic element 70 allows the drive element 64 to remain in the first position P1. For example, when the coil 68 is not energized by the control circuit module 54 and the drive element 64 is in the first position P1, the elastic force of the elastic element 70 allows the drive element 64 to remain in the first position P1, thus achieving a power-saving effect.

[0054] Preferably, when the second object 26 ( Figure 9 The image only shows accessory 46 representing the second object 26) relative to the first object 24. Figure 9 The diagram only shows the electronic lock 20 representing the first object 24) in the predetermined position R. A predetermined wall 106 of the accessory 46 can press down on the slider 98, keeping the slider 98 in a second state W2, at which time the elastic feature 100 is in a state of accumulating elastic force.

[0055] like Figure 10This is a schematic diagram of the first operation flow of an electronic lock 20 according to an embodiment of the present invention, which includes the following steps:

[0056] Step S110: The communication device 104 sets the drawer 32 to locked.

[0057] In this step S110, the communication device 104 may have an application (App) installed, and the user may send a first control signal, such as a lock signal, through the application on the communication device 104.

[0058] Step S120: Detect whether the sensor 62 is in the normally open state.

[0059] In this step S120, as Figure 9 As shown, the electronic lock 20 can detect whether the sensor 62 is in a normally open (NO) state. For example, by pressing the slider 98 through the predetermined wall 106 of the accessory 46, the slider 98 is held in the second state W2, and the sensor 62 is thus in a normally open state. This also indicates that the second object 26 is at the predetermined position R relative to the first object 24. Therefore, the sensor 62 can be used to detect whether the second object 26 is at the predetermined position R relative to the first object 24.

[0060] If so, then proceed to step S130: the drive member 64 of the electromagnetic mechanism 56 is positioned at the first position P1 according to the first power signal. In this step, when the electronic lock 20 receives the first control signal from the communication device 104, the drive member 64 can be driven to the first position P1 (e.g., reverse power, but not limited to) because the coil 68 is provided with the first power signal by the control circuit module 54. Figure 9 (As shown). And, step S140 can be performed: the drawer 32 cannot be opened. In this step, when the second object 26 (the drawer 32) is in the predetermined position R relative to the first object 24 (the cabinet 30), and the drive member 64 is in the first position P1 (e.g.) Figure 9 As shown), drawer 32 cannot be opened in the opening direction D1.

[0061] If not, proceed to step S150: the communication device 104 warns that the drawer 32 is not fully closed. In this step S150, for example, the communication device 104 may issue an audible and / or electronic message through the application to inform the user that the drawer 32 is not fully in the predetermined position R.

[0062] like Figure 11 and Figure 12As shown, the driving element 64 can be driven to the second position P2 when the coil 68 is energized by the control circuit module 54. Specifically, when the second object 26 ( Figure 11 and Figure 12 The image only shows accessory 46 representing the second object 26) relative to the first object 24. Figure 11 and Figure 12 The diagram only shows that when the electronic lock 20 represents the first object 24) is in the predetermined position R, the drive member 64 is in the second position P2, which allows the second object 26 to leave the predetermined position R.

[0063] Specifically, when the second object 26 ( Figure 11 The diagram only shows the accessory 46 (representing the second object 26) in the predetermined position R, and the drive member 64 in the second position P2 (e.g., the unlocked position). When the latch 80 of the drive member 64 is not inserted into the auxiliary part 52 (e.g., a hole or slot) of the accessory 46, the second object 26 is allowed to leave the predetermined position R relative to the first object 24 in the opening direction D1. For example, the second object 26 is displaced in the opening direction D1 to a predetermined extension position E' (e.g., ...). Figure 12 (As shown).

[0064] Preferably, the drive unit 64 can be in the second position P2 according to a second power signal provided by the control circuit module 54. For example, the drive unit 64 can be driven to the second position P2 according to the second power signal provided by the control circuit module 54 to the coil 68. Furthermore, the control circuit module 54 can provide the second power signal (e.g., forward power, but not limited to) to the coil 68 through at least one transmission unit 74, so that the drive unit 64 is driven to the second position P2 accordingly.

[0065] Preferably, when the driving element 64 is not driven by the control circuit module 54, the magnet 66 keeps the driving element 64 in the second position P2. For example, when the coil 68 is not energized by the control circuit module 54 and the driving element 64 is in the second position P2, the magnet 66 can attract the driving element 64 and keep it in the second position P2, thus achieving a power-saving effect.

[0066] Preferably, when the second object 26 ( Figure 12 The diagram only shows that accessory 46 represents the second object 26) is in the predetermined extended position E' relative to the first object 24. The predetermined wall 106 of accessory 46 no longer presses down on the slider 98, so that the slider 98 can return from the second state W2 to the first state W1 in response to the elastic release of the elastic feature 100.

[0067] It is worth mentioning that one of the slider 98 and the accessory 46 includes the guide portion 102, thus both the slider 98 and the accessory 46 have the guide portion 102. Figure 12 This only refers to the guide portion 102 of the slider 98. When the second object 26 extends from an extended position, such as the predetermined extension position E' (e.g. Figure 12 As shown, during the process of moving in the retraction direction D2 to the predetermined position R, the guide part 102 allows the accessory 46 to easily push against the slider 98, so that the predetermined wall 106 of the accessory 46 can press the slider 98 back down (as shown). Figure 11 (As shown).

[0068] like Figure 13 This is a schematic diagram of the second operation flow of an electronic lock 20 according to an embodiment of the present invention, which includes the following steps:

[0069] Step S210: The communication device 104 sets the drawer 32 to unlock.

[0070] In this step S210, the user can send a second control signal, such as an unlock signal, through the application of the communication device 104.

[0071] Step S220: The drive member 64 of the electromagnetic mechanism 56 is in the second position P2 according to the second power signal. In this step, when the electronic lock 20 receives the second control signal from the communication device 104, and the second item 26 (the drawer 32) is in the predetermined position R relative to the first item 24 (the cabinet 30) (e.g.) Figure 11 As shown), the drive unit 64 can be driven to the second position P2 based on the second power signal (e.g., forward power, but not limited to) provided by the control circuit module 54 to the coil 68.

[0072] Step S230: The drawer 32 can be opened. In this step, when the second object 26 (the drawer 32) is in the predetermined position R relative to the first object 24 (the cabinet 30), and the drive unit 64 is in the second position P2 (e.g.) Figure 11 As shown), the drawer 32 can be opened in the opening direction D1 (as shown). Figure 12 (As shown).

[0073] like Figure 14 and Figure 15 As shown, when the coil 68 fails to be energized by the control circuit module 58 and the drive unit 64 is in the first position P1, the drive unit 64 can be released from the first position P1 (e.g., the locked position) via the manual unlocking mechanism 60. Figure 14 ) Move to the second position P2 (e.g., the unlock position, such as Figure 15 ).

[0074] For example, a user can apply a force F in a predetermined direction (e.g., the opening direction D1) to the first component 84, so that the first component 84 can be linked to the second component 86, thereby driving the drive member 64 from the first position P1 (e.g., Figure 14 ) drives to the second position P2 (e.g. Figure 15 Preferably, the first component 84 has a mounting portion 108 (e.g., a hole, but not limited thereto) for binding a rope to facilitate the application of force F by the user.

[0075] Furthermore, the predetermined direction is substantially parallel to the direction of relative movement between the first object 24 and the second object 26. For example, the predetermined direction is longitudinal, and the direction of displacement of the second object 26 relative to the first object 24 is also longitudinal.

[0076] Preferably, the first component 84 is converted into a linear movement of the second component 86 via a pivoting motion. For example, when the user applies the force F to the first component 84 in the predetermined direction, the first component 84 moves from the initial state S1 (as shown in the image). Figure 14 As shown) it moves in a first pivot direction Y1 to a yaw state S2 (as shown) Figure 15 As shown), the first component 84 can be linked to the second component 86 to linearly displace relative to the base 58 in a first movement direction K1, so that the corresponding segment 86a of the second component 86 can contact the extension segment 80a of the locking tongue 80 of the driving member 64, thereby driving the driving member 64 from the first position P1 (as shown). Figure 14 ) drives to the second position P2 (e.g. Figure 15 ), and the auxiliary elastic element 90 is in a state of accumulating elastic force (e.g. Figure 15 ).

[0077] like Figure 15 and Figure 16 As shown, once the user stops applying the force F to the first component 84, the first component 84 responds to the auxiliary elastic element 90 to release the elastic force from the yaw state S2 (as shown). Figure 15 ) Return to the initial state S1 in the second pivot direction Y2 (e.g.) Figure 16 During this process, the first component 84 moves the second component 86 back to its original position in a second movement direction K2. The second pivot direction Y2 is opposite to the first pivot direction Y1, and the second movement direction K2 is opposite to the first movement direction K1.

[0078] Based on the above description, it can be seen that the improved efficacy and advantages of the present invention are as follows:

[0079] 1. When the coil 68 is not energized by the control circuit module 54, the drive member 64 can be kept in the second position P2 through the magnet 66, thus saving power; or, when the coil 68 is not energized by the control circuit module 54, the drive member 64 can be kept in the first position P1 through the elastic member 70, thus saving power.

[0080] 2. When the coil 68 fails to be energized by the control circuit module 58 and the drive member 64 is in the first position P1, the second object 26 can be actuated by applying force in a predetermined direction through the first component 84 of the manual unlocking mechanism 60, so as to move the drive member 64 from the first position P1 (e.g., the locked position) to the second position P2 (e.g., the unlocked position). The predetermined direction is substantially parallel to the direction of relative movement of the first object 24 and the second object 26, which is convenient for use.

[0081] 3. Compared with the prior art, the electromagnetic mechanism 56 of this embodiment can achieve the function of locking and unlocking through the drive part 78, the locking tongue part 80 and the magnet 66 (or the elastic member 70), and the structure is more concise.

[0082] 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.
