It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Currently, having had already appeared various smart locks with the development of technology of Internet of things, such as remote switch can be realized
The various functions such as lock, in these functions compared with based on function should be locked out the notice of state, that is, user or system clothes
Business device can know the lock state of the lock of its concern at any time.
Especially in logistic industry, either user collects package and still sends package, requires user and logistics people
The handover of member (courier).But in real life, since user is in its addressee or posts part place (for example, in family or doing
Public room) time often the working time for taking package is sent not necessarily to coincide with courier, especially courier is generally responsible for one
The package of large area is fetched and delivered, therefore it is difficult to ensure that the time of package is fetched and delivered in visiting for each user, this has often led to use
The waiting at family or the waiting for delivering personnel, this all greatly reduces the delivery efficiency of package.For this purpose, occurring various self-service
Logistics device, using with locking system cabinet and box-like formula logistics object storing apparatus, realize the delivery of package
Separation with both operations are taken out, to substantially increase package delivering efficiency, and realizes the spirit that user collects package
Activity.
Therefore, in above-mentioned self-service scheme, the lock state notice pair of the locking device of the storage lattice or the storage box of cabinet
It is very important for state in confirming the delivery state wrapped up or taking away.In other words, system or user need by being put
Enter the locking information of the logistics object container of package to confirm that package has been put into, and passes through the opening of the container and locking letter
Breath has been taken away to confirm to wrap up.But in actual use, it usually will appear the confirmation message due to the mistake of lock state, lead
Cause system judges incorrectly.For example, the locking system of existing logistics object container is mechanical structure mostly, it is usually to pass through
Lock tongue is pushed into carry out the judgement of lock state.In this case, since under unlocking condition, the lock tongue of lock is in outer
The state of dew, thus be easy to occur accidentally touch (for example, manpower accidentally touches) so that system mistake judge container door close
?.
In addition, for using for motor-driven locking device, since inside is to drive locking using motor rotation
Component carries out lock and unlock operation, therefore, in such motor-driven lock, when the rotating signal by motor determines
When lock state, if if system can not just know the true locking shape of the smart lock since motor breaks down

The location diagram of lock tongue and locking component.
It include shell 2 and lock according to the locking device 1 of one embodiment of the application shown in as shown in Figure 1, Figure 3 and Figure 4
Tongue 3.Lock tongue 3 can be instructed according to locking or unlocking in the unlocked position for being located at the outside of shell 2 and positioned at the inside of shell 2
It is moved between latched position.It shows a case that lock tongue 3 is located at outside shell 2 in Fig. 1, but those skilled in the art is come
It says, it is obvious that lock tongue 3 can also be placed in inside shell 2, and be located at shell 2 according to instruction is locked or unlocked
It is moved between external latched position and the unlocked position inside shell 2.
Shown in as shown in Figure 1, Figure 3 and Figure 4, locking device 1 may include: lock bolt 4, lock bolt fixation member inside shell 2
5, rotary shaft 6, rotating arm 7 and driver 8.Lock bolt 4 may be disposed at 10 side of opening of shell 2.The opening 10 of the shell 2 can
Shell 2 is passed in and out from it for lock tongue 3.Lock bolt 4 can act movement by the disengaging of opening 10 according to lock tongue.
In one embodiment of the application, as shown in Figure 1, Figure 3 and Figure 4 shown in, locking device 1 may include elastic rotary
Component 11.The elastic rotary component 11 setting is in 10 sides that are open, and lock bolt 4 may be configured as around the elastic rotary component 11
Rotation.Therefore, in this case, when lock tongue 3 is entered in shell 2 by opening 10, triggering elastic rotary component 11 rotates,
To drive the lock bolt 4 for being connected to elastic rotary component 11 to rotate to the position with the formation perpendicular contact of lock tongue 3, to lock
Tongue 3.
In addition, lock bolt fixation member 5 is set as to rotate around rotary shaft 6.In one embodiment of the application, lock bolt
One end of fixation member 5 is connected to rotary shaft, and its other end can squeeze lock bolt 4 with the rotation of lock bolt fixation member 5.
Specifically, when lock tongue 3 is entered in shell 2 by opening 10, lock bolt 4 is as elastic rotary component 11 is in such as first direction
It is upper rotation and engaged with lock tongue 3, meanwhile, one end that lock bolt fixation member 5 is contacted with lock bolt 4 also with lock bolt 4 rotation and revolve
Turn, thus when lock bolt 4 rotates to the position with 3 perpendicular contact of lock tongue, lock bolt fixation member 5 contacted with lock bolt 4 this one
End rotates to the position against 4 other side of lock bolt around rotary shaft 6, so that lock bolt 4 is fixed on the position with 3 perpendicular contact of lock tongue
It sets, realizes the locking to lock tongue 3.Similarly, under above-mentioned lock state, when receiving latch-release instruction, lock bolt 4 can
It is reversely rotated around elastic rotary component 11, to be detached from lock tongue 3, so that lock tongue 3 can be moved outwardly to unlock from latched position
Position.
In embodiments herein, one end of rotating arm 7 is connected to rotary shaft 6, and driver 8 can be according to control
Signal drives rotating arm 7 to control the lock bolt fixation member 5 being connected in rotary shaft 6.Particularly, rotating arm 7 can be by enclosing
Around rotary shaft 6 rotation and rotational resistance is applied to rotary shaft 6 to hinder to be connected to lock bolt fixation member 5 in a predetermined direction
Rotation, so that lock bolt fixation member 5 is limited when lock bolt 4 rotates to the closed position with lock tongue 3 with the entrance of lock tongue 3
It is made as only rotating to against the direction of lock bolt 4, and can not reversely rotate.Therefore, enable to lock bolt fixation member 5 that will lock
Door bolt 4 is fixed on the closed position with lock tongue 3, to keep lock state.Conversely, rotating arm 7 can when receiving unlock instruction
To be rotated to releasing for the direction of the rotational resistance of rotary shaft 6 under the driving of driver 8, thus 5 energy of lock bolt fixation member
It is enough to be rotated to the direction for being detached from lock bolt 4.When lock bolt fixation member 5 is detached from lock bolt 4, lock bolt 4 is anti-around elastic rotary component 11
It is detached to rotation, and with lock tongue 3, so that lock tongue 3 can realize solution from the position fastened with lock bolt 4 to the external mobile of shell 2
Lock.
In addition, after the completion of unlock, since in unlock, rotating arm 7 rotates to releasing for rotary shaft 6 by driver 8
Rotational resistance direction.In other words, after unlock is completed, since rotating arm 7 is no longer applied with rotation resistance to rotary shaft 6
Power enables lock bolt fixation member 5 to rotate freely.Therefore, in this case, even if lock tongue 3 is inserted into shell by opening 10
In body 2, and lock bolt 4 is driven to rotate to closed position, at the same lock bolt fixation member 5 also with lock bolt 4 rotation and rotate to
By the position of lock bolt 4, but the position of rotational resistance is not applied with to rotary shaft 6 since rotating arm 7 is in, lock bolt is solid
Determining component 5 can reply since elastic rotary component 11 is applied to the reverse rotational force of lock bolt 4 with the reverse rotation of lock bolt 4
To unlocked position, from being unable to lock bolt 4 securely fixing the latched position for being that lock tongue 3 fastens.
Therefore, it in embodiments herein, after unlocking completion, needs to rotate to rotating arm 7 to rotation again
Axis 6 is applied with the position of rotational resistance, and the lock bolt fixation member 5 for being thus connected to rotary shaft 6 can be logical in lock tongue 3 next time
Opening 10 is crossed when being inserted into shell 2, as lock bolt 4 moves to the position against lock bolt 4, and due to from rotary shaft 6
Resistance and lock bolt 4 is fixed on the position fastened with lock tongue 3 by jail.
The foregoing describe according to the locking of the locking device 1 of the embodiment of the present application and the process to unlock.Next
It will be described according to the lock state of the embodiment of the present application record and decision process.
Shown in as shown in Figure 1, Figure 3 and Figure 4, locking device 1 may further include switching member 9.Switching member in the figure
9 are shown as including switch block 91 and switch block 92.Switch block 91 may be provided near rotating arm 7, in order to root
The switching state according to the movement of rotating arm 7.Switch block 92 may be provided near lock bolt fixation member 5, in order to according to lock bolt
The movement of fixation member 5 and switching state.
For example, as shown in fig. 1, when receiving the instruction to unlock, driver 8 drives rotary shaft 6 will rotate
The rotation restriction site of rotation of the arm 7 from limitation for lock bolt fixation member 5 in a predetermined direction is (for example, shape shown in Fig. 3
State) rotate to the restriction cancellation position (for example, state as shown in Figure 1) for releasing the limitation.In this case, limit is moved to
System releases the rotating arm 7 of position and switch block 91 is detached from, so that switch block 91 is in non-pressing state, i.e. opening state,
Referring to state shown in Fig. 1.Simultaneously as the rotation of rotating arm 7, so that lock bolt fixation member 5 surrounds the rotation of rotary shaft 6
Limitation be released from, therefore, lock bolt fixation member 5 can be moved in Fig. 1 from the fixation position shown in Fig. 5 against lock bolt 4
Shown in fixed release position.In embodiments herein, lock bolt fixation member 5 is from the fixation position against lock bolt 4 to admittedly
Surely the movement for releasing position, which can be to be reversely rotated around elastic rotary component 11 to lock tongue 3 by lock bolt 4, is detached from the position fastened
The movement set and trigger.Specifically, in the locked state, elastic rotary component 11 is applied with reverse rotation to lock bolt 4 always
Restoring force, but since the lock bolt fixation member 5 against lock bolt 4 cannot be reversely rotated around rotary shaft 6, due to
Lock bolt fixation member 5 against so that lock bolt 4 be fixed on lock tongue 3 fasten latched position.When as mentioned above due to rotation
When the rotation of arm 7 is so that lock bolt fixation member 5 is released from around the rotation limitation of rotary shaft 6, lock bolt fixation member 5 is due to becoming
It is reversely rotated for rotary shaft 6 can be surrounded, therefore lock bolt 4 can not be fixed on latched position again, but can be with lock bolt 4
It reversely rotates and is moved to fixed releasing position, while lock bolt 4 is also reversely rotated to the unlocked position being detached from and lock tongue 3 fastens.
In above process, it when lock bolt fixation member 5 is in a fixed position, is detached from, i.e., does not press with switch block 92
Compress switch component 92, so that switch block 92 is in non-pressing state, i.e. opening state, for example, see state shown in Fig. 5.
When lock bolt fixation member 5 rotates to fixed releasing position with the reset of lock bolt 4, push switch component 92, to open
Closing component 92 becomes pressing state, i.e. closed state.
After being completed as previously described unlock operation, since lock bolt fixation member 5 is in the state of rotation restriction cancellation,
Therefore, even if in the unlocked state, lock tongue 3 is inserted into shell 2 again by opening 10, so that lock bolt 4 again moves into locking bit
It sets and lock bolt fixation member 5 again moves into fixed position, then since lock bolt fixation member 5 surrounds the rotation of rotary shaft 6
In the state not limited, lock bolt 4 can not be fixed on latched position.That is, the restoring force due to elastic rotary component 11 can make
It obtains lock bolt 4 and is returned to unlocked position, to be unable to complete lock operation.Therefore, it after unlock operation is completed, again will need
Rotating arm 7, which rotates to, rotates restriction site shown in Fig. 1, so that lock bolt fixation member 5 becomes only rotating to
The state rotated on the direction of fixed position.In other words, in this state, locking device 1 can be considered as in state to be locked,
And switch block 91 is pressed due to being moved to the rotating arm 7 of rotation restriction site, is in pressing state, i.e. closed form
State.
As described above, being able to record the various lock operations of locking device 1 using the switching member 9 of the embodiment of the present application
State, such as lock state shown in state to be locked and Fig. 4 shown in unlocked state, Fig. 3 shown in Fig. 1.It is right
It is easily understood that according to an embodiment of the present application, can be separately provided in switching member 9 for those skilled in the art
Switch block 91 or 92, that is, the lock state of 91 or 92 come record locking device 1 of switch block can be only set.
For example, when switch block 91 is only arranged, since switch block 91 is rotating restriction site according only to rotating arm 7
Movement/rotation between restriction cancellation position and change state, it is then possible to record locking device 1 lock state (that is,
Rotating arm 7 is in rotation restriction site) and lock release state (that is, rotating arm 7 is in restriction cancellation position).But it answers
It is noted that since switch block 91 only can change state according to the rotation of rotating arm 7, and as described above, rotating arm 7
Therefore, in the case where switch block 91 are only arranged, if rotating arm 7 is driven to rotation agretope after latch-release
It sets so that locking device is in state to be locked, then the state and lock state cannot be distinguished in switch block 91.Therefore, such as
Switch block 91 is only arranged in fruit, then needing to set rotating arm 7 to not rotate to rotation agretope immediately after unlocking
It sets, but the rotation that is just triggered in 3 insertion opening 10 of lock tongue, to still be able to lock bolt 4 being fixed on latched position.
In another embodiment of the application, when switch block 92 is only arranged, since switch block 92 is according only to lock bolt
The movement of fixation member 5 and change state, therefore can recorde the lock state of locking device 1 (that is, at lock bolt fixation member 5
In fixed position) and lock release state (that is, lock bolt fixation member 5, which is in fixed, releases position).With switching group is only set
Unlike the case where part 91, since the lock state of locking device 1 is directly reflected in the position of lock bolt fixation member 5, lead to
Cross switch block 92 can accurately record locking device 1 lock state (that is, lock state and unlocked state) without
Change the control setting of rotating arm 7.But the position of rotating arm 7 can not be recorded since switch block 92 is only arranged, nothing
Method further discriminates between unlocking condition and state to be locked.
Therefore, according to the another embodiment of the application, switch block 91 and 92 can be set simultaneously, so as to by opening
Close component 91 and 92 state combination come record locking device 1 above-mentioned three kinds of states (that is, lock state, unlocked state, to
Lock state).
Specifically, when receiving unlock instruction, driver 8 drives rotating arm under lock state as shown in Figure 4
7 rotate to restriction cancellation position as shown in Figure 1 around rotary shaft 6, to release the rotation limit for lock bolt fixation member 5
System, thus lock bolt 4 can due to the restoring force of elastic rotary component 11 effect and drive the reversed rotation together of lock bolt fixation member 5
Turn, so that lock bolt 4 rotates to unlocked position, and lock bolt fixation member 5 is moved to fixed releasing position.Therefore, because lock bolt
4 with lock tongue 3 departing from buckling state, lock tongue 3 is able to be moved to except opening 10, to realize locking as shown in Figure 1
The unlocked state of device 1.Under the unlocked state, rotating arm 7 relieves the pressing for switch block 91, thus switch block
91 become opening state, and 5 push switch component 92 of lock bolt fixation member, so that switch block 92 becomes closed state.Cause
This, passes through the combinations of states information (switch block 91: opening of switch block 91 and 92；Switch block 92: closure), it can sentence
It makes locking device 1 and unlocking operation is completed.
Under unlocked state as shown in Figure 1, as described above, being driven in order to realize locking when lock tongue 3 is again introduced into
Dynamic device 8 can drive rotating arm 7 to rotate to rotation restriction site, in order to solid as lock bolt 4 is moved in lock bolt fixation member 5
It is when positioning is set that lock bolt fixation member 5 is fixed in the position.Therefore, as shown in Figure 3, under the state to be locked, rotating arm 7
It is moved to rotation restriction site, and lock bolt fixation member 5 is still located at fixed releasing position.In this state, switch block
91 become pressing state (that is, closed state) due to being pressed again by rotating arm 7, and due to locking compared with unlocked state
Door bolt fixation member 5 does not move, therefore the state of switch block 92 does not change, and is still kept closed.Therefore, pass through switch
Combinations of states information (the switch block 91: closure of component 91 and 92；Switch block 92: closure), it can determine out locking dress
It sets 1 and has been in state to be locked.
Under state to be locked as shown in Figure 3, when lock tongue 3 enters in shell 2 again by opening 10, triggering
Lock bolt 4 is rotated to latched position, and the rotation of lock bolt 4 also drives lock bolt fixation member 5 mobile to fixed position simultaneously.By
In under state to be locked, lock bolt fixation member 5 is restricted around the rotation of rotary shaft 6 (that is, being merely able to revolve to fixed position
Turn, and cannot reversely rotate), therefore, lock bolt fixation member 5 postpones in arrival fixed bit and is fixed on fixed position, so as to
It is enough that lock bolt 4 is fixed on latched position, to be fastened with lock tongue 3.It is thereby achieved that lock operation, i.e. locking device 1 are again at
Lock state as shown in Figure 4.As shown in Fig. 4, in this locked condition, under the state of rotating arm 7 and state to be locked
Identical, still in rotation restriction site, therefore the state of switch block 91 does not change, and is still kept closed, and due to
Lock bolt fixation member 5 is moved to fixed position, therefore relieves the pressing for switch block 92, thus switch block 92
Become non-pressing state, i.e. opening state.Therefore, by the combinations of states information of switch block 91 and 92 (switch block 91:
Closure；Switch block 92: open), it can determine out that locking device 1 has been in the lock state.
