[0032] The terms "first", "second", "third", and the like, are merely used to distinguish descriptions, and do not represent the arrangement sequence, and cannot be understood as indicating or implying relative importance.

[0033] In addition, the terms "horizontal", "vertical", "overhanging", and the like, do not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0034] In the description of the present application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", and the like, indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product of the present application is used, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0035] In the description of the present application, unless otherwise explicitly specified and limited, the terms "set", "mount", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements.

[0036] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings.

[0037] Embodiment one:

[0038] The present application provides a kind of intelligent box lock 10, which can be applied to the door body in user's home, or the intelligent box lock 10 can be applied to the door body of base station room and the like small installation space. As shown in the drawing, Figure 1 The intelligent box lock 10 in the present application includes handle driving module 200, locking module, electrical unlocking module 300 and mechanical unlocking module 400. Handle driving module 200 includes handle 210, transmission assembly 220 and unlocking shaft 230, handle 210 is drivingly connected with unlocking shaft 230 by transmission assembly 220;Wherein, locking module has the closed state of limiting transmission assembly 220 action and the open state of allowing transmission assembly 220 action.

[0039] When the smart lock 10 is in normal operation in an electrified state, a user can send an unlocking signal to the smart lock 10 through a mobile terminal such as a smart watch or a smart phone. When the unlocking signal is received, the electrical unlocking module 300 can drive the locking module to switch from the locked state to the unlocked state, and the unlocking operation is completed after the switching is successful. The user can rotate the handle 210 to drive the transmission assembly 220 and the unlocking shaft 230 to act, and the locking bolt 2013 connected to the unlocking shaft 230 acts after the unlocking shaft 230 acts, and the user completes the door opening operation.

[0040] When the smart lock 10 is out of power, the user can insert the mechanical key into the keyhole of the mechanical unlocking module 400, make the mechanical key cooperate with the mechanical unlocking module 400, and drive the mechanical unlocking module 400 to act by the mechanical key to switch the locking module from the locked state to the unlocked state, and the unlocking operation is completed after the switching is successful. The user can rotate the handle 210 to drive the transmission assembly 220 and the unlocking shaft 230 to act, and the locking bolt 2013 connected to the unlocking shaft 230 acts after the unlocking shaft 230 acts, and the user completes the door opening operation.

[0041] When the smart lock 10 is not unlocked, the locking module is in the locked state, and the movement of the transmission assembly 220 is limited. At this time, even if the handle 210 is rotated, the transmission assembly 220 and the unlocking shaft 230 will not act, and the door opening operation cannot be completed.

[0042] As can be seen from the above, in the present application, the mechanical unlocking module 400 unlocks the smart lock 10 by changing the state of the locking module. The mechanical unlocking module 400 does not link with the unlocking shaft 230 during the unlocking operation, which alleviates the situation that the user directly pulls the mechanical key to open the door after the mechanical unlocking operation, reduces the use intensity of the mechanical unlocking module 400, and the mechanical unlocking module 400 is not easy to wear, which is beneficial to prolong the service life of the smart lock 10.

[0043] Embodiment two:

[0044] As shown in Figure 2 The transmission assembly 220 includes a driving gear 2014, a driven gear 2010, and a rack. The handle 210 is connected with the driving gear 2014, and the unlocking shaft 230 is connected with the driven gear 2010. The rack includes a first rack and a second rack which are parallel. The driving gear 2014 and the driven gear 2010 are respectively engaged with the first rack, and the driving gear 2014 and the driven gear 2010 are respectively engaged with the second rack. The rack is limited to act when the locking module is in the locked state; and the rack is allowed to act when the locking module is in the unlocked state.

[0045] As shown in Figure 3 and Figure 4As shown, the locking module includes a first locking pin 3002, a second locking pin 3012 and a locking block 3004 between the first rack and the second rack, the first rack has a first limiting slot 20061 for one end of the first locking pin 3002 to insert; the second rack has a second limiting slot 20091 for one end of the second locking pin 3012 to insert. As shown, Figure 3 As shown, in the locked state, one end of the first locking pin 3002 is inserted into the first limiting slot 20061, one end of the second locking pin 3012 is inserted into the second limiting slot 20091; the locking block 3004 is located at a first position which blocks the first locking pin 3002 from exiting the first limiting slot 20061 and blocks the second locking pin 3012 from exiting the second limiting slot 20091, and the locking block 3004, the first locking pin 3002 and the second locking pin 3012 are substantially on the same straight line; as shown, Figure 4 As shown, in the unlocked state, the locking block 3004 is located at a second position which allows the first locking pin 3002 to exit the first limiting slot 20061 and allows the second locking pin 3012 to exit the second limiting slot 20091, and the locking block 3004 is not on the same straight line with the first locking pin 3002 and the second locking pin 3012.

[0046] When unlocking, the electrical unlocking module 300 and the mechanical unlocking module 400 can drive the locking block 3004 to move from the first position to the second position, so that the locking module is switched from the locked state to the unlocked state for unlocking operation. When opening the door, the locking block 3004 does not block the first locking pin 3002 and the second locking pin 3012 at this time, then as shown, Figure 4 As shown, when the user rotates the handle 210, the first locking pin 3002 exits the first limiting slot 20061 and abuts against the edge of the first rack, the second locking pin 3012 exits the second limiting slot 20091 and abuts against the edge of the second rack, at the same time, the handle 210 drives the driving gear 2014 to rotate, the driving gear 2014 drives the first rack and the second rack to move along the straight line after rotating, the first rack and the second rack drive the driven gear 2010 and the unlocking shaft 230 to rotate when moving along the straight line, the locking bolt 2013 connected with the unlocking shaft 230 rotates after the unlocking shaft 230 rotates, and the user completes the door opening operation.

[0047] In some preferred embodiments, as shown, Figure 3 and Figure 4 As shown, the locking module further includes a first elastic member 3001 and a second elastic member 3005, the first elastic member 3001 is used to provide a restoring force for the locking pin to move into the limiting slot 40012 when the locking pin exits the limiting slot 40012; the second elastic member 3005 is used to provide a restoring force for the locking block 3004 to move from the second position to the first position.

[0048] When the user completes the door opening operation and performs the door closing operation, if the user reversely rotates the handle 210, the driving gear 2014 drives the first rack and the second rack to move along the straight line to the initial position, and the driven gear 2010 and the unlocking shaft 230 rotate to the initial position. When the first rack and the second rack move along the straight line to the initial position, the first locking pin 3002 is aligned with the first limiting groove 20061, and the second locking pin 3012 is aligned with the second limiting groove 20091. At this time, under the action of the first elastic member 3001, the first locking pin 3002 moves into the first limiting groove 20061, and the second locking pin 3012 moves into the second limiting groove 20091. Then, under the action of the second elastic member 3005, the locking block 3004 moves from the second position to the first position, and after the movement is completed, the locking module is switched from the unlocking state to the locking state; the door is automatically locked.

[0049] In the above embodiment, the gear and rack structure is used as the transmission assembly 220, so that the components in the intelligent box lock 10 can be arranged and connected more compactly, which is beneficial to making the intelligent box lock 10 thinner and improving the competitiveness of the product. Meanwhile, in the above embodiment, the locking block 3004 is switched from the locking state to the unlocking state by changing the position of the locking block 3004 to change the action state of the locking block 3004 on the locking pin, and the switching mode is simple and easy to implement. Meanwhile, after the user completes the door opening operation, the user does not need to perform any operation on the electrical unlocking module 300 and the mechanical unlocking module 400, and only by rotating the handle 210, the locking module can be automatically switched to the locking state under the action of the first elastic member 3001 and the second elastic member 3005. The intelligent degree of the intelligent box lock 10 is higher, the user intervention is less, and the user experience is improved.

[0050] Of course, it can be understood that, as shown in Figure 2 The first rack can include a first rack body 2007 and a first limiting strip 2006, the first rack body 2007 is engaged with the driving gear 2014 and the driven gear 2010, and the first limiting strip 2006 is fixed to the first rack body 2007, and the first limiting groove 20061 is arranged on the first limiting strip 2006. The second rack can include a second rack body 2017 and a second limiting strip 2009, the second rack body 2017 is engaged with the driving gear 2014 and the driven gear 2010, the second limiting strip 2009 is fixed to the second rack body 2017, and the second limiting groove 20091 is arranged on the second limiting strip 2009. For example, the first limiting strip 2006 can be fixed on the first rack body 2007 by screws, magnetic attraction, buckles or the like; and the second limiting strip 2009 can be fixed on the second rack body 2017 by screws, magnetic attraction, buckles or the like.

[0051] By setting the limiting groove 40012 on the corresponding limiting strip, the rack body can be continuously engaged with the driving gear 2014 and the driven gear 2010 when the user moves the rack body during the door opening operation, so that the user can more smoothly perform the door opening operation.

[0052] Of course, it can be understood that the above-mentioned embodiments can only include the first rack and the first locking pin 3002, that is, the second gear and the second locking pin 3012 are omitted. The transmission assembly 220 in the above-mentioned embodiment can also adopt a rotating wheel belt structure, or the transmission assembly 220 can also adopt other power transmission structures in the prior art.

[0053] Embodiment three:

[0054] As shown in Figure 5 The electrical unlocking module 300 includes an upper support 3003, a lower support 3011 detachably connected to the upper support 3003 and covered on the upper support 3003, a main control board 3009, a driving motor 3007, a rotating wheel 3006, and a driven block 3010.

[0055] The output end of the driving motor 3007 is connected with one end of the rotating wheel 3006, and the other end of the rotating wheel 3006 is provided with an eccentric shaft 30061. Figure 6 and Figure 7As shown, the driven block 3010 has a main body 30103 and a first sensing boss 30101 connected to the main body 30103. An eccentric shaft 30061 is inserted into the waist hole 301031 on the main body 30103. The locking block 3004 has a locking block body 30041 and a locking boss 30042 located above the locking block body 30041. The first sensing boss 30101 extends into the first mounting groove 300411 of the locking block body 30041. A mounting post 30102 is provided on the first sensing boss 30101. A positioning post 300412 is provided on the groove wall of the first mounting groove 300411. One end of the second elastic member 3005 is connected to the mounting post 30102, and the other end of the second elastic member 3005 is connected to the positioning post 300412. The upper bracket 3003 is provided with a receiving groove (not shown in the figure) located between the first guide groove and the second guide groove 3008, and the locking boss 30042 extends into the receiving groove.

[0056] like Figure 5 As shown, the main control board 3009 is provided with a first detection element 30092 for detecting the position of the driven block 3010; for example, the first detection element 30092 can detect the position of the driven block 3010 by detecting the position of the first sensing boss 30101. The main control board 3009 is also provided with a second detection element 30091 for detecting the position of the locking block body 30041; for example, as Figure 7 As shown, a second sensing boss 300413 may be provided on the locking block body 30041, and the second detection element 30091 can detect the position of the locking block body 30041 by detecting the position of the second sensing boss 300413.

[0057] like Figure 2 As shown, the first limiting strip 2006 may be provided with a first mounting hole 20062, and a first magnet 2008 is installed in the first mounting hole 20062; as Figure 5 As shown, the main control board 3009 is provided with a third detection element 30093, which can detect the position of the first limit bar 2006 by detecting the position of the first magnet 2008. For example, the third detection element 30093 can be a Hall sensor.

[0058] The working principle of the electrical unlocking module 300 is explained in detail below:

[0059] like Figure 3As shown, in the locking state, the first sensing boss 30101 is in contact with the right groove wall of the first mounting groove 300411. The locking boss 30042 is in a straight line with the first locking pin 3002 and the second locking pin 3012, the first protruding part 30021 is located in the first limiting groove 20061, and the second protruding part 30121 is located in the second limiting groove 20091. The first elastic member 3001 and the second elastic member 3005 are not compressed. The third detection element 30093 is aligned with the first magnetic steel 2008 and can detect the first magnetic steel 2008. When receiving the unlocking signal sent by the user through the mobile terminal, the main control board 3009 can control the driving motor 3007 to rotate to the unlocking position in the first direction. When the driving motor 3007 rotates, the driven block 3010 and the locking block 3004 move linearly to the right from the locking position to the unlocking position. When the locking block 3004 moves to the unlocking position, the locking module switches from the locking state to the unlocking state, the locking boss 30042 is not in a straight line with the first locking pin 3002 and the second locking pin 3012, and the first locking pin 3002 and the second locking pin 3012 are in a resilient state to complete the unlocking operation.

[0060] As shown in the figure, Figure 4 When the user rotates the handle 210 from the locking position to the unlocking position, the first protruding part 30021 is disengaged from the first limiting groove 20061 and abuts against the edge of the first limiting strip 2006. The first pin shaft 30022 slides in the first guide groove, and the first elastic member 3001 sleeved on the first pin shaft 30022 is compressed. The second protruding part 30121 is disengaged from the second limiting groove 20091 and abuts against the edge of the second limiting strip 2009. The second pin shaft 30122 slides in the second guide groove 3008, and the first elastic member 3001 sleeved on the second pin shaft 30122 is compressed. At the same time, the handle 210 drives the driving gear 2014 to rotate during rotation, and the driving gear 2014 drives the first rack and the second rack to move linearly in opposite directions. When the first rack and the second rack move linearly, the driven gear 2010 and the unlocking shaft 230 are rotated. After the unlocking shaft 230 is rotated, the lock tongue 2013 connected to the unlocking shaft 230 is rotated, and the user completes the door opening operation.

[0074] Embodiment five:

[0075] The mechanical unlocking module 400 includes a lock cylinder housing 4006, a lock cylinder 4008 and a knob 4001 as shown. Figure 9 The lock cylinder 4008 is rotatably arranged in the lock cylinder housing 4006. The lock cylinder 4008 has a key hole for inserting a mechanical key. The knob 4001 is connected with the lock cylinder 4008 and is configured to push the blocking block 3004 from the first position to the second position when the lock cylinder 4008 rotates.

[0076] The working principle of the mechanical unlocking module 400 will be explained in detail as follows:

[0077] In the blocking state, the first sensing boss 30101 is in contact with the right groove wall of the first installation groove 300411. The blocking boss 30042, the first blocking pin 3002 and the second blocking pin 3012 are located on a straight line. The first protruding part 30021 is located in the first limiting groove 20061, and the second protruding part 30121 is located in the second limiting groove 20091. The first elastic member 3001 and the second elastic member 3005 are not compressed. The blade of the lock cylinder 4008 is connected with the lock cylinder housing 4006, and the lock cylinder 4008 cannot drive the knob 4001 to rotate.

[0078] When the user inserts the mechanical key into the keyhole for mechanical unlocking, the leaves of the lock cylinder 4008 are retracted, the lock cylinder 4008 is in a disengaged state with the lock cylinder housing 4006, and when the mechanical key is turned, the lock cylinder 4008 and the pusher 4001 are also turned. Figure 3 、 Figure 4 、 Figure 7 and Figure 10 As shown, the locking block 3004 is provided with an unlocking block 30043 connected with the locking block body 30041, and after the pusher 4001 is turned, the locking block 3004 and the driven block 3010 are moved from the first position to the second position by pushing the unlocking block 30043. The driven block 3010 drives the drive motor 3007 to rotate in the process of moving, and the spring in the drive motor 3007 is compressed and stored when the drive motor 3007 rotates. When the mechanical key is turned to the unlocking position, the pusher 4001 is turned to the unlocking position, the locking block 3004 and the driven block 3010 are moved to the unlocking position, the locking module is switched from the locking state to the unlocking state, the locking boss 30042 is not in a straight line with the first locking pin 3002 and the second locking pin 3012, and the first locking pin 3002 and the second locking pin 3012 are in a resilient state to complete the unlocking operation. When the mechanical key stops rotating, the spring in the drive motor 3007 is decompressed to move the driven block 3010 from the unlocking position to the locking position, and the second elastic element 3005 is compressed after the movement is completed.

[0079] When the user turns the handle 210 to the unlocking position, the first protruding part 30021 is detached from the first limiting groove 20061 and abuts against the edge of the first limiting strip 2006, the first pin shaft 30022 slides in the first guide groove, and the first elastic element 3001 sleeved on the first pin shaft 30022 is compressed; the second protruding part 30121 is detached from the second limiting groove 20091 and abuts against the edge of the second limiting strip 2009, the second pin shaft 30122 slides in the second guide groove 3008, and the first elastic element 3001 sleeved on the second pin shaft 30122 is compressed. At the same time, the handle 210 drives the driving gear 2014 to rotate in the process of turning, the driving gear 2014 drives the first rack and the second rack to move linearly in opposite directions, the first rack and the second rack drive the driven gear 2010 and the unlocking shaft 230 to rotate when moving linearly, the locking bolt 2013 connected with the unlocking shaft 230 is turned after the unlocking shaft 230 is turned, and the user completes the door opening operation.

[0080] When the user rotates the handle 210 from the unlocking position to the locking position after the door closing operation, the handle 210 drives the driving gear 2014 to rotate, and the driving gear 2014 drives the first rack and the second rack to move linearly in opposite directions. When the first rack and the second rack move to the initial position, the first protruding part 30021 is aligned with the first limiting groove 20061, the second protruding part 30121 is aligned with the second limiting groove 20091, the first elastic member 3001 is decompressed to make the first protruding part 30021 move to the first limiting groove 20061, the second protruding part 30121 moves to the second limiting groove 20091, and the first pin shaft 30022 slides in the first guide groove, and the second pin shaft 30122 slides in the second guide groove 3008. After the first protruding part 30021 and the second protruding part 30121 move, the second elastic member 3005 is decompressed to make the locking block 3004 move linearly to the left from the unlocking position to the locking position.

The actuator 4001 has a containing groove 4005, one end of the lock cylinder 4008 is connected with the bottom surface of the containing groove 4005, and the side surface of the containing groove 4005 surrounds part of the lock cylinder shell 4006. Exemplarily, the lock cylinder 4008 can be connected with the bottom surface of the containing groove 4005 by screws, magnetic attraction, buckles and the like. The lock cylinder 4008 module is provided with a mounting frame 4004 connected with the lock shell module 100. Exemplarily, the mounting frame 4004 can be connected with the lock shell module 100 by screws, magnetic attraction, buckles and the like. The mounting frame 4004 is provided with a second mounting groove 40061, the lock cylinder shell 4006 passes through the second mounting groove 40061 and is fixed in the second mounting groove 40061 by a limiting pin 4003. The actuator 4001 is provided with a tab 40011, when the actuator 4001 rotates, the tab 40011 drives the locking block 3004 and the driven block 3010 to move from the first position to the second position by pushing the unlocking block 30043. The mounting frame 4004 is provided with a limiting groove 40012, and the actuator 4001 rotates in the limiting groove 40012.
