[0040] Refer to Figures 1 to 3 . Figure 1 FIG. is a perspective view of the hook lock device 10 according to some embodiments of the present invention in a locked state. Figure 2 FIG. is a perspective view of the hook lock device 10 according to some embodiments of the present invention in an unlocked state. Figure 3 FIG. is a block diagram of the control circuit 50 of the hook lock device 10 according to some embodiments of the present invention. The hook lock device 10 includes a body 20, a hook body 30, a lock body 40 and a control circuit 50. The hook body 30 is connected to one end of the body 20 (hereinafter referred to as the first end 21), and forms a hanging notch 60 with the body 20. For example, one end of the hook body 30 is connected to one end of the body 20 (i.e., the first end 21), and the other end of the hook body 30 (i.e., the free end 31) is spaced apart from the other end of the body 20 (hereinafter referred to as the second end 22) by a distance to form the hanging notch 60. An article (not shown) is hung on the hook body 30 by being placed in the hanging notch 60.
[0041] The free end 31 of the hook body 30 has an engaging portion 32. The lock body 40 includes a connecting end 41 and a fastening end 42. The connecting end 41 is movably connected to the other end (i.e., the second end 22) of the main body 20. In the locked state, the fastening end 42 of the lock body 40 is latched with the engaging portion 32 of the hook body 30 to close the hanging notch 60. Specifically, by latching the fastening end 42 of the lock body 40 with the engaging portion 32 of the hook body 30, the lock body 40 can cover the hanging notch 60, thereby closing the hanging notch 60. At this time, the item placed in the hanging notch 60 and hung on the hook body 30 cannot escape from the hanging notch 60 because the hanging notch 60 is closed. In this way, the item can be prevented from being stolen. In the unlocked state, the fastening end 42 of the lock body 40 is separated from the engaging portion 32 of the hook body 30. In this way, the hanging notch 60 is presented because it is not covered by the lock body 40. At this time, the item can freely escape from the hanging notch 60, so that the user can obtain the item.
[0042] The control circuit 50 is disposed inside the hook body 30. The control circuit 50 includes an NFC antenna 51, a driving module 52, and a processor 53. The driving module 52 is connected to the engaging portion 32. The processor 53 is connected to the NFC antenna 51 and the driving module 52. The processor 53 is, for example, an NFC chip. The NFC antenna 51 receives a first wireless signal. The first wireless signal is from the user's electronic device, and the user places the first verification information in the first wireless signal through the electronic device. The processor 53 obtains and verifies the first verification information from the first wireless signal, and outputs a driving signal to the driving module 52 when the verification is passed. The driving module 52 drives the engaging portion 32 to release the fastening end 42 in response to receiving the driving signal, so that the lock body 40 presents an unlocked state. In an exemplary embodiment, the driving module 52 includes a solenoid valve. In the locked state, the clamping rod of the solenoid valve clamps the fastening end 42 latched with the engaging portion 32. After the first verification information passes the verification, the solenoid valve is actuated in response to the driving signal, and contracts its clamping rod to release the engaging portion 32 from the fastening end 42, and makes the lock body 40 present an unlocked state. In another exemplary embodiment, the driving module 52 includes a motor and a pushing member. The pushing member is located inside the engaging portion 32, and the pushing member abuts against the fastening end 42 in the locked state. After the first verification information passes the verification, the motor is actuated in response to the driving signal, and pushes the pushing member towards the opening of the engaging portion 32, so that the pushing member pushes the fastening end 42 out of the engaging portion 32, and makes the lock body 40 present an unlocked state. In this way, by using an electronic verification method to determine whether to make the lock body 40 enter the unlocked state, the security of the hook lock device 10 can be improved.
[0043] In some embodiments, the first verification information is password information. The password information is, for example, a personal identification number (PIN) entered by the user through the electronic device. The processor 53 stores password verification information. The verification process of the first verification information is to verify whether the password information matches the password verification information. Specifically, when the password information matches the password verification information, the processor 53 determines that the verification is passed, and thus the lock body 40 is in an unlocked state. When the password information does not match the password verification information, the processor 53 determines that the verification fails, and thus the lock body 40 remains in a locked state.
[0044] In some embodiments, the first verification information is ciphertext information. The processor 53 decrypts the ciphertext information to obtain decryption information. The verification process of the first verification information is to verify whether the decryption information matches the plaintext information. The plaintext information is in the second wireless signal sent before the NFC antenna 51 receives the first wireless signal. For example, before the NFC antenna 51 receives the first wireless signal, the processor 53 uses the serial number stored by it as the plaintext information or generates a random digital code through a random number generator as the plaintext information. Then, the processor 53 stores the plaintext information and inserts the plaintext information into the second wireless signal to send the second wireless signal to the user's electronic device via the NFC antenna 51. After that, the user's electronic device encrypts the plaintext information (such as symmetric encryption or asymmetric encryption) to generate ciphertext information, inserts the ciphertext information as the first verification information into the first wireless signal, and sends the first wireless signal to the hook lock device 10. Asymmetric encryption is, for example, the RSA algorithm or the Digital Signature Algorithm (DSA). When the user's electronic device executes the digital signature algorithm on the plaintext information, the generated ciphertext information is a kind of digital signature information. The processor 53 obtains the ciphertext information in the first wireless signal via the NFC antenna 51 and decrypts the ciphertext information to obtain decryption information. When the decryption information matches the plaintext information, the processor 53 determines that the verification is passed, and thus the lock body 40 is in an unlocked state. When the decryption information does not match the plaintext information, the processor 53 determines that the verification fails, and thus the lock body 40 remains in a locked state.
[0045] In some embodiments, the NFC antenna 51 receives a third wireless signal before receiving the first wireless signal. The processor 53 obtains and verifies the second verification information from the third wireless signal and executes the verification process of the first verification information when the verification is passed. In this way, by using dual electronic verification to determine whether to unlock the lock body 40, the security of the hook lock device 10 can be further improved.
[0046] In some embodiments, the second verification information is account information. The account information is, for example, the account name input by the user through the electronic device and its corresponding password. The processor 53 stores account verification information. The verification process of the second verification information is to verify whether the account information matches the account verification information. Specifically, when the account information matches the account verification information, the processor 53 determines that the verification is passed, and thus executes the verification process of the first verification information. When the account information does not match the account verification information, the processor 53 determines that the verification fails, and thus keeps the lock body 40 in the locked state, places the verification failure message into the fourth wireless signal, and sends the fourth wireless signal to the user's electronic device via the NFC antenna 51. In this way, the user can be informed that the account information he entered is incorrect, so that he can re-enter new account information.
[0047] In some embodiments, one of the fastening end 42 of the lock body 40 and the engaging portion 32 of the hook body 30 is provided with a bolt and the other is provided with a bolt groove. In the locked state, the bolt and the bolt groove are bolted to each other.
[0048] In some embodiments, the connecting end 41 of the lock body 40 has a rotating member to drive the displacement of the lock body 40 in the unlocked state. Specifically, in the unlocked state, the rotating member rotates under the external force generated when the engaging portion 32 releases the fastening end 42, and drives the displacement of the lock body 40. For example, the lock body 40 is displaced horizontally or vertically along with the rotation direction of the rotating member. The rotating member is, for example, a knob. In this way, the displacement direction of the lock body 40 can be restricted to reduce the risk of damage to the lock body 40 due to random displacement.
[0049] In some embodiments, the connecting end 41 of the lock body 40 has a spring to make the lock body 40 bounce away from the hook body 30 in the unlocked state. Specifically, in the locked state, the spring at the connecting end 41 of the lock body 40 is compressed by the external force generated when the fastening end 42 locks the engaging portion 32, thereby accumulating elastic restoring force. In the unlocked state, since the engaging portion 32 releases the fastening end 42, the extrusion force of the spring is removed. At this time, the spring releases the elastic restoring force it has accumulated to make the lock body 40 bounce away from the hook body 30 by means of the elastic restoring force.
[0050] Refer to Figure 4, is a block diagram of the control circuit 50 of the hook lock device 10 according to some embodiments of the present invention. In some embodiments, the control circuit 50 further includes a light-emitting module 54. The light-emitting module 54 is implemented by, for example, a light-emitting diode. When the NFC antenna 51 receives the first wireless signal, the processor 53 controls the light-emitting module 54 to present a first light-emitting state. In some embodiments, in addition to receiving the first wireless signal, when the NFC antenna 51 receives the third wireless signal, transmits the second wireless signal, or transmits the fourth wireless signal, the processor 53 can also control the light-emitting module 54 to present the first light-emitting state. In other words, when the NFC antenna 51 receives or transmits a wireless signal, the processor 53 controls the light-emitting module 54 to present the first light-emitting state, but the present invention is not limited thereto. For example, when the NFC antenna 51 receives or transmits a wireless signal carrying different information each time, the processor 53 controls the light-emitting module 54 to present different light-emitting states. In this way, the user can know that the hook lock device 10 is currently transmitting a wireless signal. When the driving module 52 drives the engaging portion 32, the processor 53 controls the light-emitting module 54 to present a second light-emitting state different from the first light-emitting state. For example, the first light-emitting state is a flashing light, and the second light-emitting state is a constant light. In this way, the user can know that the hook lock device 10 is unlocking.
[0051] In some embodiments, the control circuit 50 further includes a voltage stabilizing circuit 55. The voltage stabilizing circuit 55 is connected to the NFC antenna 51, the driving module 52, and the light-emitting module 54. When the NFC antenna 51 receives the first wireless signal (or receives the third wireless signal, or transmits the second wireless signal or transmits the fourth wireless signal), an induced power supply is generated due to the magnetic field effect. The voltage stabilizing circuit 55 stabilizes the induced power supply (such as boosting or bucking) to provide a regulated power supply to the driving module 52 and the light-emitting module 54, so that the driving module 52 and the light-emitting module 54 can operate normally. The voltage stabilizing circuit 55 can be implemented by a circuit having a voltage stabilizing function formed by active components (such as transistors) and / or passive components (such as resistors, inductors, and capacitors). In some embodiments, the processor 53 has a built-in module with a voltage stabilizing function, so the processor 53 can directly operate normally through the induced power supply without the voltage stabilizing circuit 55. In other embodiments, if the processor 53 does not have a built-in module with a voltage stabilizing function, the processor 53 is connected to the voltage stabilizing circuit 55, so that the voltage stabilizing circuit 55 can provide a regulated power supply to the processor 53 and enable the processor 53 to operate normally.
[0052] In some embodiments, the processor 53 stores a storage information, which includes the information of the owner of the locked object, the name information of the locked object, the production information of the locked object, the storage period information of the locked object, the record form of the receipt and return of the locked object, and the recent unlocking time. The information of the owner of the locked object, the name information of the locked object, the production information of the locked object, and the storage period information of the locked object are sent to the control circuit 50 of the hook lock device 10 through a wireless signal containing these information by an electronic device when the user locks an item into the hook body 30 of the hook lock device 10, so that the processor 53 of the control circuit 50 can analyze and store these information from the wireless signal. The information of the owner of the locked object refers to the name of the administrator of the item, the name information of the locked object refers to the name of the item, the production information of the locked object refers to the manufacturing data such as the production date and instrument number of the item, and the storage period information of the locked object refers to the storage validity period of the item.
[0053] When the user locks an item into the hook body 30 of the hook lock device 10, a wireless signal containing the return record information is sent to the control circuit 50 of the hook lock device 10 through an electronic device, so that the processor 53 of the control circuit 50 can analyze and store the return record information into the record form of the receipt and return of the locked object stored by it. The return record information records information such as the name of the returned item, the item return time (i.e., the time when the item is locked into the hook body 30 of the hook lock device 10), and the name of the return personnel.
[0054] When the user takes out the item locked into the hook body 30 of the hook lock device 10, the control circuit 50 of the hook lock device 10 generates and stores the receipt record information into the record form of the receipt and return of the locked object stored by it. The receipt record information records information such as the name of the taken-out item, the item receipt time (i.e., the time when the item locked into the hook body 30 of the hook lock device 10 is taken out), and the name of the receipt personnel (which can be input into the control circuit 50 through a wireless signal when the user unlocks the hook lock device 10).
[0055] When the user takes out the item locked into the hook body 30 of the hook lock device 10, the control circuit 50 of the hook lock device 10 generates an unlocking time and updates the recently stored unlocking time according to the unlocking time. The recently stored unlocking time refers to the time when the hook lock device 10 is in the unlocked state for the last time.
[0056] Refer to Figure 5 FIG. is a schematic diagram of the application of the hook lock device 10 according to some embodiments of the present invention. In some embodiments, the hook lock device 10 further includes a mounting base 70 for connecting to an external housing (such as the housing of a locomotive 80), and the main body 20 of the hook lock device 10 is located on the mounting base 70. In some embodiments, the mounting base 70 is fixed to the external housing by means of screwing, buckling or pasting.
[0057] Reference Figure 6 , which is a schematic diagram of the mounting base 70 of the hook lock device 10 according to some embodiments of the present invention. In some embodiments, the mounting base 70 has a carrier 71. The bottom end of the carrier 71 is connected to the second end 22 of the body 20, and the top end of the carrier 71 has an open notch (also referred to as the first open notch 72). Thus, the user can also hang an item (not shown in the figure) on the carrier 71 by placing it into the first open notch 72, thereby increasing the storage space of the hook lock device 10.
[0058] Reference Figure 6 and Figure 7 . Figure 7 , which is a schematic diagram of the mounting base 70 of the hook lock device 10 according to some embodiments of the present invention. In some embodiments, the mounting base 70 has a clamping member 73. The clamping member 73 has two clamping arms 74. One end of the two clamping arms 74 is connected to the second end 22 of the body 20, and the other end of the two clamping arms 74 forms an open notch (also referred to as the second open notch 75). The user places an external housing (such as the column 81 or the handle 82 of the motorcycle 80) into the second open notch 75 and closes the second open notch 75 by screwing, so that the hook lock device 10 is fixed to the external housing through the mounting base 70.
[0059] Reference Figure 8 , which is a schematic diagram of the mounting base 70 of the hook lock device 10 according to some embodiments of the present invention. In some embodiments, one end of the two clamping arms 74 of the clamping member 73 of the mounting base 70 is connected to the second end 22 of the body 20 and has a spring. The spring is compressed by the external force applied by the user to store elastic restoring force, and the other end of the two clamping arms 74 forms the second open notch 75. The user places an external housing (such as the handle 82 of the motorcycle 80) into the second open notch 75 and removes the squeezing force applied to the spring. At this time, the spring releases the elastic restoring force it has stored, so that the other ends of the two clamping arms 74 approach each other to close the second open notch 75. Thus, the hook lock device 10 is fixed to the external housing through the mounting base 70.
[0060] In summary, according to some embodiments, the present case does not require the user to keep the physical key, which can protect the items hung on the hook body from being stolen. And since there is no physical key, the security of the hook lock device can be improved. For example, the hook lock device is not easily damaged or cracked. In some embodiments, the control circuit of the present case uses NFC technology to transmit wireless signals and generates power through the magnetic field effect of NFC technology. Therefore, no battery and no external power supply are required. Thus, the maintenance costs of the battery and external power supply can be eliminated, and the convenience of the hook lock device can be increased.
