[0003] With the development of the sharing economy, currently, shared lockers, shared rental cabinets, shared rental reclining chairs, shared baby carriages, shared wheelchairs, shared folding nursing beds, etc. have become a brand-new business model. The renter can open the shared lock by scanning the code with a mobile phone. When stopping using, the renter only needs to open the lock cabinet again to take out or return the item, or directly fasten the lock body and the lock piece. That is, when the shared lock is locked, it is confirmed as automatic settlement, and the entire rental service is completed. The whole process requires no manual intervention and provides a good user experience.

[0004] Currently, the main problems of the locks used for shared devices are high cost, inconvenient use, high power consumption, and that the RFID card reading cannot read the card information 100%, resulting in failed returns and easy disputes.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] It should be understood that when used in this specification and the appended claims, the terms "comprises" and "comprising" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0045] It should also be understood that the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0046] It should be further understood that the term "and / or" used in the specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0047] Referring to Figure 1 , an embodiment of the present invention provides a shared intelligent lock, including a bolt 100, a first circuit board 11, a first conductive contact 12, a lock body 200, a second circuit board 21 and a second conductive contact 22; the first circuit board 11 is disposed on the bolt 100, and the first circuit board 11 stores an identifiable identifier; the first conductive contact 12 is disposed on the bolt 100 and is electrically connected to the first circuit board 11; the lock body 200 is for the bolt 100 to be inserted therein, and the lock body 200 is used to lock or release the bolt 100; the second circuit board 21 is disposed on the lock body 200, and the second circuit board 21 is used to receive the identifier; the second conductive contact 22 is disposed on the lock body 200 and is electrically connected to the second circuit board 21; wherein, when the bolt 100 is inserted, the lock body 200 locks the bolt 100, the second conductive contact 22 contacts and conducts with the first conductive contact 12 so that the second circuit board 21 receives the identifier from the first circuit board 11, and when the identifier verification fails, the lock body 200 releases the bolt 100.

[0048] By implementing this embodiment, a first circuit board 11 and a first conductive contact 12 connected thereto are provided in the bolt 100, and a second circuit board 21 and a second conductive contact 22 connected thereto are provided in the lock body 200. Among them, the first conductive contact 12 stores an identifiable identifier. When the bolt 100 is inserted into the lock body 200, the bolt 100 is immediately locked. The first conductive contact 12 contacts and conducts with the second conductive contact 22, and the first circuit board 11 and the second circuit board 21 form an electrical connection. The first circuit board 11 sends the identifier to the second circuit board 21 for verification. If the identifier verification fails, the lock body 200 releases the bolt 100. Thus, only when the identifier verification is successful can the return be realized, and any other return method cannot succeed in returning, effectively preventing false returns in a violent manner and improving safety.

[0049] Exemplarily, the shared intelligent lock of this embodiment can be applied to multiple shared scenarios. For example, shared lockers, shared rental cabinets, shared rental reclining chairs, shared baby carriages, shared wheelchairs, shared folding nursing beds, etc. The bolt 100 in this embodiment is used to be fixed to the shared device. For example, it is locked on the nursing bed by a chain. The lock body 200 is installed on the host device 300. The host device 300 is communicatively connected to the server 400. The server 400 counts and charges for the borrowing of the shared device. When borrowing, the user can unlock and take out the shared device by scanning the QR code. When returning, the user inserts the bolt 100 into the lock body 200. After successful identification, the return is successful.

[0050] It should be noted that the verification of the identifier in this embodiment can be verified by the second circuit board 21 of the lock body 200, or the second circuit board 21 can send the identifier to the server 400. After verification by the server 400, the verification result is returned to the second circuit board 21, which is not limited herein. Among them, the identifier refers to the name used to represent the bolt 100. For example, PHC001. The verification process of the identifier can be to match the identifier with the identifier list of the shared device being borrowed. If the match is successful, it indicates that the identifier verification is successful. If the match fails, it indicates that the identifier verification fails, and the lock body 200 releases the bolt 100. After the return fails, the lock body 200 can remind the user of the return failure through a buzzer or the flashing of an LED light. Of course, it can be understood that there can also be other ways. For example, the bolt 100 is pushed out of the lock body 200, and the user can clearly know that the current return fails. The specific implementation method is as follows:

[0051] In one embodiment, continue to refer to Figure 1, the lock body 200 includes: a lock case 23, a locking mechanism 24, an unlocking mechanism 25, and a pushing mechanism 26; the locking mechanism 24 is disposed within the lock case 23 and is used to lock or release the bolt 100; the unlocking mechanism 25 is disposed within the lock case 23 and is connected to the second circuit board 21, and the unlocking mechanism 25 is used to drive the locking mechanism 24 to release the bolt 100; the pushing mechanism 26 is disposed within the lock case 23 and is connected to the second conductive contact 22, and the pushing mechanism 26 is used to apply a thrust to the second conductive contact 22 so that the second conductive contact 22 pushes the first conductive contact 12, thereby pushing the bolt 100 out of the lock case 23. Specifically, a first circuit board 11, a first conductive contact 12, a locking mechanism 24, an unlocking mechanism 25, and a pushing mechanism 26 are installed within the lock case 23. When the bolt 100 is inserted, the locking mechanism 24 directly locks the bolt 100. After the identification verification fails, the unlocking mechanism 25 drives the locking mechanism 24 to release the bolt 100, and finally the pushing mechanism 26 pushes the bolt 100 out of the lock body 200. Thus, the user can clearly know that the return is not successful, and the user can try to return again to avoid the user misidentifying the successful return and failing to settle the charge in time.

[0052] In one embodiment, referring to Figure 2 , the locking mechanism 24 includes a lock tongue 241 installed in the lock case 23 and a transmission assembly 242. The transmission assembly 242 is respectively in transmission connection with the lock tongue 241 and the second conductive contact 22; wherein, when the bolt 100 is inserted, the first conductive contact 12 pushes the second conductive contact 22 to move, and drives the lock tongue 241 to lock the bolt 100 through the transmission assembly 242. Specifically, when returning the shared device, the bolt 100 is inserted into the lock body 200, the first conductive contact 12 contacts the second conductive contact 22. As the bolt 100 is inserted, the first conductive contact 12 pushes the second conductive contact 22 to move. By using the movement of the second conductive contact 22, the lock tongue 241 is driven through the transmission assembly 242, thereby locking the bolt 100. The locking operation is simple and convenient, and cleverly uses the movement of pushing the first conductive contact 12 to drive the lock tongue 241 to complete the locking. There is no need to lock by means of electricity such as detection or induction. The bolt 100 is directly locked by mechanical transmission cooperation, and the reliability is high.

[0053] In a specific implementation, referring to Figure 2, the transmission assembly 242 includes: a lock hole seat 2421, a transmission card 2422, a driving piece 2423, an elastic member 2425, and an inclined block 2424. The lock hole seat 2421 is installed on the lock housing 23. The lock hole seat 2421 is provided with a receiving cavity 2421a for inserting the bolt 100. A lock hole 2421b communicating with the receiving cavity 2421a is formed on one side of the lock hole seat 2421. A through hole 2421c communicating with the receiving cavity 2421a is formed on the lock housing 23. The second conductive contact member 22 includes a push rod 221 and a neck portion 222 extending radially along the push rod 221. The push rod 221 movably passes through the through hole 2421c and partially passes through the through hole 2421c and is located in the receiving cavity 2421a. The transmission card 2422 includes a card body 24221 and a pushing piece 24222 connected to the card body 24221. The pushing piece 24222 abuts against the neck portion 222. The card body 24221 is slidably connected to the side of the lock hole seat 2421 where the lock hole 2421b is formed. The card body 24221 is connected to the lock tongue 241. Wherein, when the card body 24221 slides to the first position, it drives the lock tongue 241 to extend into the receiving cavity 2421a. When the card body 24221 slides to the second position, it drives the lock tongue 241 to retract from the receiving cavity 2421a. The driving piece 2423 is slidably connected to the card body 24221. The driving piece 2423 is connected to the unlocking mechanism 25. The elastic member 2425 abuts against the driving piece 2423 and the card body 24221 at both ends. The elastic member 2425 is used to provide elastic force for the card body 24221 along the sliding direction of the card body 24221. The inclined block 2424 is arranged on the lock housing 23. The inclined block 2424 is used to abut against the neck portion 222 so that the neck portion 222 is disengaged from abutting against the pushing piece 24222. Wherein, the neck portion 222 drives the pushing piece 24222 to move in the direction of insertion of the bolt 100 to drive the card body 24221 to move in the same direction to the second position. When the neck portion 222 is disengaged from abutting against the pushing piece 24222, the card body 24221 moves reversely and resets to the first position under the elastic force of the elastic member 2425 so that the lock tongue 241 locks the bolt 100.

[0054] Specifically, referring to Figure 2 and Figure 3, a socket 231 is provided on the lock housing 23. The receiving cavity 2421a of the lock hole seat 2421 is installed on the lock housing 23 corresponding to the socket 231. The bolt 100 can be inserted into the receiving cavity 2421a through the socket 231. A lock hole 2421b is opened on one side of the lock hole seat 2421 perpendicular to the insertion direction of the bolt 100. The lock hole 2421b communicates with the receiving cavity 2421a. The lock tongue 241 is inserted into the lock hole 2421b. The lock tongue 241 can extend and retract in the lock hole 2421b. When it extends into the receiving cavity 2421a, the bolt 100 can be locked, and when it retracts from the receiving cavity 2421a, the bolt 100 is released. That is, the lock tongue 241 is provided on one side surface of the lock hole seat 2421 and extends from the side surface to lock the bolt 100.

[0055] Referring to Figure 4 , in this embodiment, a transmission card 2422 is used to drive the lock tongue 241 to extend and retract in the lock hole 2421b. The card body 24221 of the transmission card 2422 can slide relative to the lock hole seat 2421 and can drive the lock tongue 241 to extend and retract during the sliding process. There are many ways for the card body 24221 to drive the lock tongue 241 to extend and retract, which are not limited here. The card body 24221 of this embodiment is slidably connected to the lock hole seat 2421 through a guide rail 2421d. Specifically, when the card body 24221 slides relative to the lock hole seat 2421 to the first position, the lock tongue 241 extends from the lock hole 2421b and extends into the receiving cavity 2421a to lock the bolt 100; when the card body 24221 slides relative to the lock hole seat 2421 to the second position, the lock tongue 241 retracts from the receiving cavity 2421a and retracts into the lock hole 2421b to release the bolt 100. That is, when the card body 24221 moves to the first position, the bolt 100 is locked, and when the card body 24221 moves to the second position, the bolt 100 is released. It should be noted that in the initial state, that is, when the lock body 200 does not insert the bolt 100, the card body 24221 is in the first position, that is, the lock tongue 241 extends into the receiving cavity 2421a, which can prevent malicious returners from inserting non-matching objects such as toothpicks and cards into the lock body 200.

[0056] In one embodiment, referring to Figure 5, the bolt 241 is a ball, and the card body 24221 is provided with a slideway 24221A that abuts against the ball. The slideway 24221A includes a straight section 24221A1 and a hemispherical section 24221A2. When the ball abuts against the straight section 24221A1, the ball extends into the receiving cavity 2421a. When the ball abuts against the hemispherical section 24221A2, the ball retracts from the receiving cavity 2421a. Specifically, the hemispherical section 24221A2 is located at one end of the straight section 24221A1. The hemispherical section 24221A2 is close to the socket 231 of the lock body 200, and the straight section 24221A1 is far from the socket 231 of the lock body 200. The hemispherical section 24221A2 is a hemispherical groove, and the ball can be partially received in the hemispherical section 24221A2. When the slideway 24221A slides to a position where the hemispherical section 24221A2 is opposite to the lock hole 2421b, the ball can be received in the hemispherical section 24221A2, and the ball retracts from the receiving cavity 2421a. At this time, the card body 24221 is in the second position. When the slideway 24221A slides to a position where the straight section 24221A1 is opposite to the lock hole 2421b, the ball is abutted by the straight section 24221A1, and the ball extends into the receiving cavity 2421a. At this time, the card body 24221 is in the first position. In this embodiment, the locking method of matching the ball with the slideway 24221A is adopted, with a simple and convenient structure, smooth sliding, and no jamming that may cause inability to return, improving the reliability of return.

[0057] The through hole 2421c is arranged in the direction in which the lock hole seat 2421 inserts the bolt 100, and the through hole 2421c communicates with the receiving cavity 2421a. The push rod 221 passes through the through hole 2421c and extends into the receiving cavity 2421a, and the neck 222 is located outside the lock hole seat 2421. The neck 222 abuts against the pushing piece 24222 of the transmission card 2422. Therefore, when the push rod 221 is pushed by the bolt 100 in the inserting direction, the pushing piece 24222 can be driven to move in the inserting direction. The card body 24221 connected to the pushing piece 24222 is slidably connected to the lock hole seat 2421. Thus, when the pushing piece 24222 moves in the inserting direction, the card body 24221 can be driven to slide in the inserting direction. Since the card body 24221 is in the first position in the initial state, when the bolt 100 is inserted to push the push rod 221 and then drive the card body 24221 to move in the inserting direction, the card body 24221 is driven to move to the second position, and at this time, the bolt 241 retracts from the receiving cavity 2421a.

[0058] Refer to Figure 7, a cam 2424 is provided on the lock housing 23. The cam 2424 has an inclined surface. During the movement of the neck 222, the neck 222 abuts against the inclined surface of the cam 2424, and the inclined surface lifts the neck 222, so that the neck 222 is disengaged from the abutment with the pushing piece 24222, and further the pushing piece 24222 cannot continue to move in the insertion direction.

[0059] Continue to refer to Figure 4 , the unlocking mechanism 25 is connected to the driving piece 2423. The driving piece 2423 is slidably connected to the card body 24221. At the same time, an elastic member 2425 is provided and abuts between the driving piece 2423 and the card body 24221. Specifically, a slide rail 24221B is provided on the side of the card body 24221 facing away from the lock hole seat 2421. A slider is provided on the driving piece 2423, and the slider cooperates with the slide rail 24221B to achieve sliding. Among them, a middle section of the slide rail 24221B provided on the card body 24221 is disconnected and cleared. The slider of the driving piece 2423 is composed of left and right sliding pieces 24232. A space for accommodating the elastic member 2425 is formed by surrounding the left and right sliding pieces 24232. The elastic member 2425 is accommodated in this space, and a gap for inserting into the slide rail 24221B is left between the left and right sliding pieces 24232. During assembly, the elastic member 2425 is located at the position where the middle of the slide rail 24221B is disconnected and cleared, and is accommodated in the space surrounded by the left and right sliding pieces 24232. Thus, both ends of the elastic member 2425 abut against the driving member and the card body 24221 respectively, so that the elastic member 2425 can provide an elastic force in the sliding direction of the card body 24221. Of course, it can be understood that the connection structure of the driving piece 2423, the card body 24221 and the elastic member 2425 can also be other ways, as long as the elastic member 2425 can provide an elastic force in the sliding direction of the card body 24221. Since the driving piece 2423 is connected to the unlocking mechanism 25 and the driving piece 2423 remains relatively fixed when the unlocking mechanism 25 is not unlocked, when the card body 24221 slides relative to the lock hole seat 2421, a restoring force can be generated under the elastic force of the elastic member 2425 to drive the card body 24221 to reset.

[0060] Refer to Figures 6 - 10 The transmission process of the lock body 200 locking the bolt 100 is described below:

[0061] S1: Refer to Figure 6 and Figure 7 and Figure 8, the bolt 100 is inserted into the receiving cavity 2421a from the socket 231. The first conductive contact 12 of the bolt 100 abuts against the push rod 221 passing through the through hole 2421c, and pushes the push rod 221 in the direction of insertion of the bolt 100. The push rod 221 moves in the direction of insertion of the bolt 100. Since the neck 222 of the push rod 221 abuts against the pushing piece 24222 of the transmission card 2422, the neck 222 can drive the push rod 221 to move in the same direction as the insertion direction of the bolt 100. At this time, the card body 24221 connected to the pushing piece 24222 also moves in the same direction (i.e., also in the direction of insertion of the bolt 100). The card body 24221 thus moves from the first position (in the initial state) to the second position, driving the locking tongue 241 to retract from the receiving cavity 2421a. Furthermore, the bolt 100 can be smoothly inserted without being blocked by the locking tongue 241.

[0062] S2: Refer to Figure 8 and Figure 9 as well as Figure 10 , during the process of the neck 222 pushing the pushing piece 24222 to move in the insertion direction of the bolt 100, the neck 222 encounters the inclined block 2424 provided on the lock housing 23. The neck 222 abuts against the inclined surface of the inclined block 2424, and the inclined surface pushes the neck 222 upwards, so that the neck 222 is disengaged from abutting against the pushing piece 24222. Finally, the card body 24221 connected to the pushing piece 24222 no longer moves in the insertion direction of the bolt 100. At this time, since the elastic member 2425 can apply an elastic force in the sliding direction of the card body 24221, the card body 24221 can be reset and rebound from the second position under the action of the elastic force, and slide back to the first position, thereby driving the locking tongue 241 to extend into the receiving cavity 2421a to lock the bolt 100.

[0063] Thus, the process of inserting and locking the bolt 100 is completed. The locking of the bolt 100 can be completed only through the mechanical transmission structure, without the need for power-on detection or induction actions. The locking operation method is convenient, the locking time is short, and the user experience is good.

[0064] In an embodiment, refer to Figure 8 and Figure 10, the unlocking mechanism 25 includes: a motor 251 connected to the second circuit board 21. The motor 251 has an output shaft, and a thread 252 is provided on the circumferential surface of the output shaft; a clamping portion 24231 is provided on the driving piece 2423, and the clamping portion 24231 is clamped on the thread 252; wherein, the rotation of the output shaft drives the driving piece 2423 to move, and further drives the transmission card 2422 to slide to the second position so that the locking tongue 241 releases the bolt 100. In this embodiment, the motor 251 is connected to the second circuit board 21, and the motor 251 controls the operation of the motor 251 according to the verification result given by the second circuit board 21. When the verification result is a failure, the motor 251 is driven to work, and the motor 251 drives the driving piece 2423 to move in a direction away from the insertion direction of the bolt 100. Specifically, the clamping portion 24231 on the driving piece 2423 is clamped between two adjacent turns of the thread of the output shaft. Thus, when the output shaft rotates, the clamping portion 24231 can be driven to move along the axial direction of the output shaft through the rotation of the thread 252, wherein the axial direction of the output shaft is set in the insertion direction of the bolt 100. Therefore, under the drive of the motor 251, the driving piece 2423 moves in a direction away from the insertion direction of the bolt 100 to drive the card body 24221 to also move in a direction away from the insertion direction of the bolt 100. Thus, the card body 24221 moves from the first position to the second position, and the locking tongue 241 retracts from the receiving cavity 2421a, thereby releasing the locking of the bolt 100. After the motor 251 realizes unlocking, it drives the driving piece 2423 to reset, and the driving piece 2423 drives the card body 24221 back to the first position, and the locking tongue 241 extends into the receiving cavity 2421a again. Of course, it can be understood that in other embodiments, the unlocking mechanism 25 can also be other linear motion structures that can drive the driving piece 2423 to reciprocate in the insertion direction of the bolt 100.

[0065] In one embodiment, referring to Figure 8 , the pushing mechanism 26 includes: a conductive torsion spring 261 and an abutting block 262. The conductive torsion spring 261 is sleeved on the push rod 221, one end is connected to the neck portion 222, and the other end is connected to the second circuit board 21; the abutting block 262 is provided with a notch 2621 for the push rod 221 to pass through, and the conductive torsion spring 261 abuts against the neck portion 222 and the abutting block 262 respectively.

[0066] During the movement of the push rod 221, the push rod 221 passes through the notch 2621, and the torsion spring is compressed by the neck 222 and the abutting block 262. The torsion spring is in a compressed state, storing elastic potential energy. When the identification verification fails, the bolt 100 is released, and the bolt 100 is in an unlocked state. At this time, the compressed torsion spring returns to its natural state, releasing elastic energy, and the push rod 221 pushes the first conductive contact 12 under the elastic force of the torsion spring, so that the bolt 100 pops out from the receiving cavity 2421a of the lock hole seat 2421.

[0067] In addition, by using the conductivity of the conductive torsion spring 261 and connecting the conductive torsion spring 261 to the second circuit board 21, the electrical connection between the first circuit board 11 and the second circuit board 21 can be realized, ensuring the reliability of data transmission. In other embodiments, the lock hole seat 2421 can be made of a conductive material, such as metal, and the lock hole seat 2421 is connected to the second circuit board 21 through a wire, and the electrical connection between the first circuit board 11 and the second circuit board 21 can also be realized.

[0068] Further, referring to Figure 8 , one end of the conductive torsion spring 261 is connected to the neck 222, and a downward pressing force can be provided to the neck 222 toward the inclined surface of the inclined block 2424. Since the neck 222 will be pushed up by the inclined block 2424 during the movement, by using the downward pressing force provided by the torsion spring toward the inclined block 2424, it can be avoided that the neck 222 is always in an upwardly pushed state, ensuring that the neck 222 can tightly press the inclined block 2424 every time it moves, improving the reliability of locking.

[0069] In one embodiment, referring to Figure 11, the plug 100 includes a plug 100 housing 13 and an insulating sleeve 14. The plug 100 housing 13 includes a contact head 131 and a main body 133 connected to the contact head 131. The contact head 131 is provided with a through hole 1311. The insulating sleeve 14 is sleeved on the first conductive contact 12, and the insulating sleeve 14 passes through the through hole 1311. Specifically, the main body 133 is columnar, the contact head 131 is bullet-shaped, the first circuit board 11 is installed on the main body 133, one end of the first conductive contact 12 is connected to the first circuit board 11, and the other end is inserted into the insulating sleeve 14. A through hole 1311 is provided at the top end of the contact head 131, and the insulating sleeve 14 is inserted into the through hole 1311 of the contact head 131, thereby forming a multi-ring-shaped contact head 131. Among them, the innermost ring is the first conductive contact 12, the second innermost ring is the insulating sleeve 14 sleeved on the first conductive contact 12, and the outermost ring is the housing part of the contact head 131. During the electrical connection process, the first conductive contact 12 is the positive electrode, and the insulating sleeve 14 is the ground wire. In this embodiment, by providing the through hole 1311 in the contact head 131, the first conductive contact 12 and the insulating sleeve 14 are exposed, and electrical connection can be achieved only through point contact during the insertion process, with a simple structure and convenient implementation.

[0070] In this embodiment, referring to Figure 12 , a locking engagement portion 132 is formed by depression between the contact head 131 and the main body 133. Specifically, the outer contour of the engagement portion 132 is smaller than the outer contours of the contact head 131 and the main body 133. Thus, the balls in the above embodiment can be embedded into the engagement portion 132 to engage therewith, thereby completing the locking of the plug 100. The locking structure is simple and low-cost.

[0071] Specifically, the plug 100 housing 13 is formed by a zinc alloy mold, with the main body made of zinc alloy material and nickel-plated. The plug 100 housing 13 is connected to the ground of the second circuit board 21, and data transmission is separated by the insulating sleeve 14. A hole is left at the tail of the main body 133, and it can be bound to the shared device through a chain. The second circuit board 21 can be fixed by pins.

[0072] In other embodiments, referring to Figure 1 and Figure 8, a clearance notch 214 is provided at the position of the second circuit board 21 corresponding to the notch 2621 of the abutting block 262, and a first toggle switch 211 is provided at the position of the second circuit board 21 adjacent to the clearance notch 214. When the push rod 221 moves in the direction of inserting the bolt 100, the push rod 221 passes through the notch 2621 of the abutting block 262 and continues to move towards the clearance notch 214 of the second circuit board 21. The push rod 221 touches the toggle switch and toggles the first toggle switch 211. The first toggle switch 211 is used to start the second circuit board 21 to read the identifier from the first circuit board 11, and the first circuit board 11 sends the identifier to the second circuit board 21.

[0073] In other embodiments, continue to refer to Figure 1 , a second toggle switch 212 and a third toggle switch 213 are further provided on the second circuit board 21. The second toggle switch 212 and the second switch are arranged on the moving stroke of the pushing piece 24222, and the pushing piece 24222 toggles the second toggle switch 212 and the third toggle switch 213. The second toggle switch 212 is used to detect whether the motor 251 pushes the card body 24221 to the first position; the third toggle switch 213 is used to detect whether the motor 251 pushes the card body 24221 to the second position. Thus, when the card body 24221 does not slide to the predetermined position, the motor 251 can control the card body 24221 to slide to the predetermined position to ensure the reliability of the lock.

[0074] In other embodiments, refer to Figure 13 , a mechanical unlocking hole 232 for ejecting the bolt 100 is provided on the lock housing 23, and the mechanical unlocking hole 232 is provided at the position corresponding to the pushing piece 24222. The mechanical unlocking hole 232 is used for manually unlocking the bolt 100 when the lock body 200 and the bolt 100 are stuck. The maintenance personnel can insert a hard object into the mechanical unlocking hole 232 to push the pushing piece 24222, push the pushing piece 24222 in the direction of inserting the bolt 100, the pushing piece 24222 drives the card body 24221 to move towards the second position, thereby driving the lock tongue 241 to release the bolt 100, and the bolt 100 pops out to complete the mechanical unlocking, avoiding the situation of being locked and improving the fault tolerance rate of the lock.

[0075] Refer to Figure 14 , an embodiment of the present invention further provides a shared intelligent lock system, which includes a host 300, a plurality of shared intelligent locks, and a server 400. The shared intelligent lock is the shared intelligent lock described in the above embodiment. The host 300 is connected to the shared intelligent lock through a narrowband Internet of Things, the host 300 is communicatively connected to the server 400, and the server 400 is used to verify the identifier.

[0076] Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. NB-IoT is built on the cellular network, consuming only about 180 kHz of bandwidth, and can be directly deployed on GSM networks, UMTS networks, or LTE networks to reduce deployment costs and achieve smooth upgrades. NB-IoT is an emerging technology in the IoT field, supporting cellular data connections for low-power devices in wide area networks, and is also called Low Power Wide Area Network (LPWAN). NB-IoT supports efficient connections for devices with long standby times and high requirements for network connections. It has the characteristics of wide coverage, many connections, high speed, low cost, low power consumption, and excellent architecture.

[0077] This embodiment realizes the communication connection between the shared intelligent lock and the host 300 based on NB-IoT. Using NB-IoT can achieve ultra-low power consumption. The static power consumption can reach 39 μA, and the static power consumption of the lock and key is less than 1 μA. Moreover, this embodiment can use the host 300 to connect multiple devices. Through online communication, one host 300 can drive 1 - 256 locks, greatly reducing the cost. And this embodiment realizes the return by identifying and verifying the identifier. Therefore, the bolt 100 can be returned in different slots. For example, it can be returned remotely without affecting the settlement and billing. The host 300 of this embodiment is also provided with a power switch, which is used to wake up the power supply of the main board. The NB module is in a dormant state usually to reduce power consumption. When unlocking, press the button once to wake up and connect to the network.

[0078] In this embodiment, referring to Figure 15 , the second circuit board 21 includes an MCU (U1), a first diode D1, a first capacitor C1, a second capacitor C2, and a first resistor R1. The first resistor R1 and the first capacitor C1 form a reset circuit and are connected to the MCU (U1). The anode of the first diode D1 is used to connect to the first conductive contact 12, and the anode of the first diode D1 is also connected to the MCU (U1). The cathode of the first diode D1 is connected to the second capacitor C2. Among them, the function of D1 is to prevent reverse current. When the bolt 100 is inserted, the current flows through D1 to charge C2. When the charge reaches a certain level, the MUC starts to read the identifier. Among them, U1 is the MCU, J1 is the download program interface, and J2 is the contact conductive interface.

[0079] The working process of this embodiment is described as follows:

[0080] S1: The bolt 100 is inserted into the lock body 200, and the lock body 200 locks the bolt 100;

[0081] S2: The second circuit board 21 reads the identifier of the first circuit board 11, sends the identifier to the host 300, and then the host 300 sends the identifier to the server 400;

[0082] S3: The server 400 verifies the identifier and returns the verification result to the host 300;

[0083] S4: The host 300 receives the verification result returned by the server 400 and returns the verification result to the second circuit board 21;

[0084] S5: When the second circuit board 21 receives a successful verification result, it does not control the motor 251 to operate;

[0085] S6: When the second circuit board 21 receives a failed verification result, it controls the motor 251 to work to unlock the bolt 100 and eject the bolt 100.

[0086] By implementing this embodiment, by using one host 300 to drive multiple shared smart locks and using contactless reading of the information of the shared device, the information of the shared device can be read 100%, false return of the device is eliminated, the cost is greatly reduced compared with one lock for one slot, and at the same time, the convenience and reliability of use are greatly improved.

[0087] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
