Description

[Technical Field]

[0001] The present invention relates to a system of an electronic lock and an electronic key, in particular, the electronic lock is not provided with a power source, and the electronic key matches and compares the pairing setting information, and transmits power to the electronic lock to activate the locking and unlocking operations. [Background technology]

[0002] Conventional locking tools require a corresponding physical metal key to open the locking tool, and conventional locking tools are found everywhere in our daily lives, such as in residential gates and doors, car and motorcycle locks, office doors, and drawer locks. As a result, users need to carry a large number of keys on their bodies to lock or unlock them. In addition, various keys generally come in different shapes and sizes, and there are many of them. When carrying or storing keys, whether in a pocket or a wallet, they are very difficult to organize, heavy, and bulky. Furthermore, keys are easy to lose or forget to carry when going out, which often causes inconvenience to users when locking or unlocking.

[0003] Conventional locking tools are made up of various parts, including locking pins, sliders, shafts, and cams. A physical metal key is inserted into the keyhole of the lock cylinder, which rotates to move the shaft. The cam on the shaft rotates to push the slider, which then pushes the locking pin, completing the locking of the locking tool. However, conventional locking tools have a large number of parts and the connections between them are complex, requiring complicated manufacturing processes. After each part is manufactured, it is assembled one by one, which requires manpower and assembly time, resulting in high manufacturing costs and keeping the price of locking tools high.

[0004] The design of commercially available electronic locks typically requires computer setup, and existing password encryption technologies require encryption keys for encryption. To increase the encryption difficulty, encryption keys with more bytes are used, or the uniqueness of biometric characteristics is used as a verification condition to prevent unauthorized cracking. Keys with more bytes require calculations by a more powerful processor, require more storage space, and require a special verification module to identify biometric characteristics, increasing hardware design costs.

[Figure 5] FIG. 2 is a schematic diagram of an edit management device according to another embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0025] Referring to FIG. 1, an electronic lock and electronic key system 1 includes an electronic key 2 and an electronic lock 3. When the electronic key 2 is connected to the electronic lock 3 and paired, pairing information is stored in the electronic key 2 and the electronic lock 3, respectively, completing the pairing operation. The electronic key 2 is then connected to the electronic lock 3 to be locked or unlocked. If it is determined that the pairing information matches, locking or unlocking is performed. Here, the pairing information includes at least one electronic encryption key, or in a mechanism for verifying the deletion encryption key, the pairing information includes the deletion encryption key and at least one electronic encryption key.

[0026] Referring to FIG. 2, the electronic key 2 is a handheld device, such as a mobile phone, a remote control, a key ring, or a USB flash drive. The electronic key 2 includes a first processing module 22, a first storage module 23, a power supply module 21, and a first terminal 24. The first processing module 22 is electrically connected to the first storage module 23, the power supply module 21, and the first terminal 24, respectively. The first storage module 23 can selectively store at least one electronic encryption key or an erasure encryption key according to different functional requirements.

[0027] The first process module 22 is the computing core of the electronic key 2. The first process module 22 can be selectively configured to automatically generate at least one electronic encryption key. The pairing setting information can include at least one electronic encryption key, or the mechanism for verifying the deletion encryption key can include an deletion encryption key and at least one electronic encryption key. The first process module 22 can be, for example, but is not limited to, a microcontroller (MCU) or a module configured with various active and passive components. The first process module 22 can include units such as a central processing unit (not shown), a memory unit (not shown), a clock unit (not shown), and various input and output interfaces (not shown). In one embodiment of the present invention, the first process module 22 corresponds to an integrated circuit chip on which multiple units are integrated. By integrating multiple units on a micro-integrated integrated circuit chip, the volume of the first process module 22 can be reduced, which is convenient for installation in the electronic key 2 and is effective in space utilization, making it preferable. The external size of the electronic key 2 can be designed to be micro-sized, and the first process module 22 can serially or parallelly transmit status signals, pairing setting information, and lock or unlock commands by connecting the first terminal 24 to the second terminal 34. The first process module 22 can selectively determine whether the pairing setting information transmitted by the second process module 32 matches at least one electronic encryption key stored in the electronic key 2, thereby conveniently determining whether to send a lock or unlock command to the second process module 32 to perform the corresponding lock or unlock operation.When the first terminal 24 and the second terminal 34 are connected, the status signal determines whether the electronic key 2 or the electronic lock 3 is associated with a pairing setting or is not associated with a pairing setting, and determines whether a pairing setting operation needs to be performed after connection, or whether a corresponding locking or unlocking operation needs to be performed if the pairing setting information is determined to match.If the electronic key 2 or the electronic lock 3 stores pairing setting information for at least one electronic encryption key, the electronic key 2 or the electronic lock 3 is associated with a pairing setting.If the electronic key 2 or the electronic lock 3 does not yet store pairing setting information for at least one electronic encryption key, the electronic key 2 or the electronic lock 3 is not associated with a pairing setting.

[0028] In addition, when the first terminals 24 of different electronic keys are connected to each other, a status signal or authorization operation is transmitted serially or in parallel. When the first terminal 24 of the electronic key 2 is connected to another first terminal 24, the status signal is transmitted such that the first process module 22 of the electronic key 2 determines whether the electronic key 2 is associated with a pairing setting or is not associated with a pairing setting, and determines that an authorization operation needs to be performed after connection. If the pairing setting information of at least one electronic encryption key is stored in the electronic key 2, the electronic key 2 is associated with a pairing setting. If the pairing setting information of at least one electronic encryption key is not stored in the electronic key 2, the electronic key 2 is not associated with a pairing setting.

[0029] The first storage module 23 is a storage device such as a memory or a hard disk, and is used to store pairing setting information for each electronic lock 3. When the electronic lock 3 has not yet been connected to the electronic key 2 and paired, the second storage module 33 does not contain pairing setting information. After the electronic key 2 is connected to the electronic lock 3 and pairing is established, the second storage module 33 stores pairing setting information. The pairing setting information may include at least one electronic encryption key, or the verification mechanism for the deletion encryption key may include the deletion encryption key and at least one electronic encryption key.

[0030] The power supply module 21 is a rechargeable or replaceable battery. The power supply module 21 is electrically connected directly or indirectly to the first process module 22, the first storage module 23, and the first terminal 24 to provide the necessary power to the first process module 22, the first storage module 23, and the first terminal 24. The indirect electrical connection refers to supplying power to the first storage module 23 and the first terminal 24 via the first process module 22. The electronic key 2 also includes a warning module (not shown). The warning module may be, for example, an LED indicator light, a buzzer, or a vibration unit. The warning module generates a warning signal when the first process module 22 detects that the power of the power supply module 21 is lower than a set value. The warning signal may be, for example, a vibration warning, a sound warning, a flashing light warning, or at least one of the above warning methods. The electronic key 2 uses the warning signal to warn the user to replace or charge the battery as soon as possible, effectively preventing problems such as being unable to lock or unlock the car.

[0031] The electronic key can choose whether to use a sleep state to save power or not. For example, the electronic key 2 enters a sleep state when it is idle. For example, when the electronic key has not been used for several minutes, it starts entering the sleep state to reduce the power consumption of the power module 21. When the electronic key 2 is in a sleep state, it can wake up the electronic key 2 when it receives a trigger signal. For example, the electronic key 2 can further include at least one button, such as a start button. Pressing the start button generates a trigger signal to wake up the first process module 22. The electronic key 2 enters a sleep state when the first process module 22 completes a deletion operation, encryption key deletion operation, authorization operation, pairing operation, locking operation, or unlocking operation. Here, the deletion operation refers to deleting an encryption key or at least one electronic encryption key stored in the electronic key 2 or the electronic lock 3. The encryption key deletion operation is performed by setting and storing the encryption key in the electronic key 2. For example, when the electronic key 2 is in a sleep state and is connected to the electronic lock 3, a trigger signal is generated the moment the electronic key 2 and the electronic lock 3 are connected, which then wakes up the first process module 22 and restores the electronic key 2 to an operational state. The sleep state design can effectively extend the usage time of the electronic key 2 and reduce the frequency of replacing or charging the power module 21, but the present invention is not limited to the sleep state.

[0032] The first terminal 24 is the connection interface of the electronic key 2, and the first terminal 24 transmits signals to the electronic lock 3 via a transmission line and also supplies power. The first process module 22 communicates with the electronic lock 3 via the first terminal 24. The power supply module 21 supplies power to the electronic lock 3 via the first terminal 24. The electronic lock 3 operates using the power from the power supply module 21. The first terminal 24 can be, for example, USB, Thunderbolt, RS-232, or a proprietary hardware specification.

[0033] 3, the electronic lock 3 includes a second process module 32, a second storage module 33, a lock cylinder module 31, and a second terminal 34. The second process module 32 is electrically connected to the second storage module 33, the lock cylinder module 31, and the second terminal 34. The power required for the electronic lock 3 is provided by the external electronic key 2, eliminating concerns about power shortages and improving the environmental resistance of the electronic lock 3. The electronic lock 3 of the present invention is not limited to locking tools such as bicycle locks, window locks, padlocks, suitcase locks, and drawer locks, but can also be used for any mechanism that requires locking.

[0034] The second process module 32 is the computing core of the electronic lock 3 and can be selectively configured to automatically generate at least one electronic encryption key. The pairing setting information can include at least one electronic encryption key, or the mechanism for verifying the deletion encryption key can include a deletion encryption key and at least one electronic encryption key. The second process module 32 and the first process module 22 have the same structure, so a repeated description will not be provided here. The second process module 32 is connected to the first terminal 24 via the second terminal 34 for communication, transmitting status signals and pairing setting information serially or in parallel. The second process module 32 can also be selectively configured to determine whether the pairing setting information transmitted by the first process module 22 matches at least one electronic encryption key stored in the electronic lock 3, thereby conveniently determining whether to perform the corresponding locking or unlocking operation. When the first terminal 24 and the second terminal 34 are connected, the status signal determines whether the electronic key 2 or the electronic lock 3 is linked to a pairing setting or is not linked to a pairing setting, and determines whether it is necessary to perform a pairing setting operation after connection or to perform a matching determination for the corresponding locking or unlocking operation.

[0035] The second storage module 33 is a storage device such as a memory or a hard disk. The second storage module 33 is used to store pairing setting information, which includes at least one electronic encryption key. Alternatively, in accordance with the encryption key deletion verification mechanism, the pairing setting information can include an encryption key deletion and at least one electronic encryption key. When the electronic lock 3 has not yet been connected to the electronic key 2 and pairing has not been established, the second storage module 33 does not contain at least one electronic encryption key in the pairing setting information. After the electronic key 2 and the electronic lock 3 are connected and paired, the pairing setting information is stored in the second storage module 33.

[0036] The electronic lock 3 is a shape memory alloy lock, and the lock cylinder module 31 includes a shape memory alloy unit (SMA) (not shown) and a latch unit (not shown). The shape memory alloy unit includes at least one metal alloy whose shape can be reversibly changed within a specific temperature range. The memory alloy unit and the latch unit in the lock cylinder module 31 are interconnected, and the latch unit is, for example, a lock pin or a combination of a lock pin and an interlocking mechanism. The memory alloy unit and the latch unit are interconnected and can move between a locked position and an unlocked position, thereby realizing the locking or unlocking function.

[0037] When current flows through the shape memory alloy unit, thermal energy is generated from the electrical energy, causing the temperature of the alloy material of the shape memory alloy unit to rise. When the temperature rises to a certain temperature range, the alloy material of the shape memory alloy unit will undergo a phase change and deform, directly or indirectly pulling the latch unit to move between the locked and unlocked positions, thereby locking or unlocking the electronic lock 3. The structure of the shape memory alloy unit in the lock cylinder module 31 is simple, the motor design is omitted, the operating design structure of the memory alloy unit and the latch unit is simple and low-cost, and the manufacturing process is simple. The lock cylinder module 31 uses a shape memory alloy unit to move the latch unit, which is driven internally in the lock cylinder module 31, reducing damage caused by mechanical failure of the motor and making the electronic lock more reliable and adaptable. Due to the above characteristics, the shape memory alloy unit can replace the complex structural design of traditional locking tools. Temperature changes are used to change the shape of the shape memory alloy unit, which moves the latch unit to move between the locking and unlocking positions, thereby completing the locking or unlocking operation. However, the locking or unlocking operation of the electronic lock 3 in the present invention is not limited to this.

[0038] The second terminal 34 is the connection interface for the electronic lock 3. The first terminal 24 and the second terminal 34 of the electronic key 2 and the electronic lock 3 are electrically connected via a transmission line, respectively, to transmit status signals, pairing setting information, and lock or unlock commands to each other. Since the electronic lock 3 does not have its own power source, the power provided by the power module 21 of the electronic key 2 is supplied to the electronic lock 3 via the connection between the second terminal 34 and the first terminal 24, and the electronic lock 3 operates and operates using the power from the power module 21. Here, the first terminal 24 can be, for example, USB, Thunderbolt, RS-232, or a proprietary hardware specification.

[0039] When the pairing setting information includes at least one electronic encryption key, if the electronic lock 3 is not paired with any electronic keys 2, the pairing setting information without an electronic encryption key in the second storage module 33 will be used to set the electronic encryption key of the electronic lock 3 by connecting the first terminal 24 of the electronic key 2 with the second terminal 34 of the electronic lock 3. The power supply module 21 will transmit power to the electronic lock 3 through the connection between the first terminal 24 and the second terminal 34. The second process module 32 and the first process module 22 will transmit signals. The first process module 22 will detect whether the pairing setting information exists in the electronic lock 3. For example, the first process module will issue a query command, and then the second process module 32 will send a status signal to the first process module 22 to determine whether the electronic encryption key is stored in the electronic lock 3. Upon receiving the status signal, the first process module 22 will perform a pairing setting operation and determine whether to perform the corresponding locking or unlocking operation.

[0040] When the pairing setting information includes at least one electronic encryption key, the pairing setting operation can be explained as follows: When the first terminal 24 and the second terminal 34 are electrically connected and the electronic key 2 and the electronic lock 3 are paired, the first process module 22 and the second process module 32 communicate with each other; if the electronic lock 3 does not have an electronic encryption key, the first process module 22 or the second process module 32 automatically generates at least one random number as at least one electronic encryption key, and simultaneously stores the pairing setting information including the automatically generated at least one electronic encryption key in the first storage module 23 of the electronic key 2 and the second storage module 33 of the electronic lock 3, completing the pairing setting operation without the need for computer setup; and the electronic key 2 repeatedly performs pairing setting operations with multiple electronic locks 3, storing the automatically generated random numbers through pairing setting with the multiple electronic locks 3. At least one electronic encryption key can be stored, and the at least one electronic encryption key can be a random number, at least a pair of random numbers, or three or more random numbers. The at least one electronic encryption key can be generated by the first process module 22, the second process module 32, or jointly generated by the first process module 22 and the second process module 32. The joint generation of at least one electronic encryption key by the first process module 22 and the second process module 32 is defined as the first process module 22 and the second process module 32 respectively generating at least one electronic encryption key, storing it in the first storage module 23 and the second storage module 33, and discriminating it through mutual communication. Here, the at least one electronic encryption key is generated as a random number, and the content of the at least one electronic encryption key cannot be spied on or known by anyone, so the at least one electronic encryption key has high confidentiality.

[0041] The first storage module 23 of the electronic key 2 stores at least one electronic encryption key, which is linked to multiple electronic locks 3 and contains multiple pairing setting information corresponding to each electronic lock 3. In other words, one electronic key 2 can open multiple electronic locks 3 via multiple electronic encryption keys in the multiple pairing setting information stored in the first storage module 23. The electronic key 2 can automatically link pairing settings with hundreds of lock tools. This eliminates the need to carry multiple one-to-one matching keys when opening multiple lock tools, as is the case with conventional lock tools, greatly improving user convenience in locking and unlocking.

[0042] Furthermore, if the pairing setting information is set to include at least one electronic encryption key, the electronic key 2 is authorized to another electronic key 2, for example, at least one pairing setting information stored in the first storage module 23 of the electronic key 2 and linked to and corresponding to at least one electronic lock 3, i.e., all or part of at least one electronic encryption key, is stored in the other electronic key 2, and the other electronic key 2 is defined as a slave electronic key, and after authorization, all or part of at least one electronic encryption key of the authorized electronic key 2 is added to the slave electronic key 2.

[0043] In the mechanism for verifying the deletion encryption key, a corresponding deletion encryption key can be set for each electronic key 2, for example, it can be preset before shipping, the deletion encryption key can be stored in the first storage module 23 via the first terminal 24, before the electronic key 2 is connected to the electronic lock 3, the first storage module 23 stores only the deletion encryption key, the deletion encryption key can be set in association with the product information of the electronic key 2, for example, the deletion encryption key can be obtained using the manufacturing lot number in calculation, or a specific digit of the manufacturing lot number can be the deletion encryption key, or The editing management device 4 can set or delete the deletion encryption key via the editing management device 4, which is connected to the first terminal 24 of the electronic key 2. The editing management device 4 can download and store, via transmission from the first terminal 24, the deletion encryption key that is the same as the deletion encryption key set and stored in the editing management device 4 at the time of shipment of the electronic key 2 or a deletion encryption key that the editing management device 4 has set itself, into the first storage module 23. Therefore, each electronic key 2 can have the same or different deletion encryption key. The deletion encryption key is also used to determine the pairing setting authority between the electronic key 2 and the electronic lock 3 and to restrict the authorization authority of the electronic key 2 for the other electronic key 2.

[0044] When the electronic lock 3 has not yet been paired with any electronic key 2, the pairing setting information without the deletion encryption key or electronic encryption key in the second storage module 33 is set to the pairing setting information of the deletion encryption key or at least one electronic encryption key of the electronic lock 3 via the connection between the first terminal 24 of the electronic key 2 and the second terminal 34 of the electronic lock 3. The power supply module 21 transmits power to the electronic lock 3 via the connection between the first terminal 24 and the second terminal 34. When the electronic lock 3 receives power, the second process module 32 and the first process module 22 send signals. The first process module 22 detects whether the electronic lock 3 has pairing setting information. For example, the first process module 22 issues a query command, and then the second process module 32 sends a status signal to the first process module 22. Furthermore, when the first terminal 24 and the second terminal 34 are connected, the status signal determines whether the electronic lock 3 is associated with a pairing setting or is not associated with a pairing setting. If the electronic lock 3 stores pairing setting information having an encryption key or at least one electronic encryption key, the electronic lock 3 is associated with a pairing setting. If the electronic lock 3 does not yet store pairing setting information having an encryption key or at least one electronic encryption key, the electronic lock 3 is not associated with a pairing setting. When the first process module 22 receives the status signal, it determines whether to perform the pairing setting operation, locking operation, or unlocking operation process.

[0045] The pairing setup operation in the mechanism for verifying the deletion encryption key is as follows: After the first process module 22 detects a signal via the first terminal 24 and the second terminal 34 that the electronic lock 3 has not yet been paired, the first process module 22 or the second process module 32 automatically generates at least one random number as at least one electronic encryption key, stores the at least one electronic encryption key in the first storage module 23 or the second storage module 33, and stores the deletion encryption key of the electronic key 2 in the second storage module 33. Thus, the second storage module 33 of the electronic lock 3 that has completed pairing setup is provided with pairing setup information including the deletion encryption key and at least one electronic encryption key. When the electronic key 2 is sequentially connected to multiple electronic locks 3 that have not been paired, the first process module 22 or the second process module 32 automatically generates multiple random numbers as multiple pairing setting information. The second storage module 33 of each electronic lock 3 stores the corresponding pairing setting information, including the deletion encryption key of the electronic key 2 and at least one electronic encryption key. The pairing setting information stored in the first storage module 23 of the electronic key 2 includes the deletion encryption key of the electronic key 2 and at least one electronic encryption key associated with the deletion encryption key. The first storage module 23 stores multiple electronic encryption keys associated with multiple electronic locks 3. That is, a single electronic key 2 can open multiple electronic locks 3 via the multiple electronic encryption keys stored in the first storage module 23. The electronic key 2 can automatically perform pairing setting operations associated with the deletion encryption keys on hundreds of lock tools. This eliminates the need to carry multiple keys that match each other when opening multiple lock tools, as in the past, greatly improving user convenience when locking and unlocking.

[0046] In the verification mechanism of the erasure encryption key, the erasure encryption key can be designed as, for example, at least 8 bytes as needed, and since each byte is 8 bits, there are 264 possible combinations of the erasure encryption key. One of the functions of the deletion encryption key is to manage the control authority of the electronic key 2 and the electronic lock 3. The control authority includes the authority of the electronic key 2 to change or delete the deletion encryption key and electronic encryption key of the electronic lock 3. Another function of the deletion encryption key is to limit the authorization of the electronic key 2 to another electronic key 2. For example, an electronic key 2 with a deletion encryption key can use its authorization function to authorize another electronic key 2 to control the locking or unlocking of the electronic lock 3. After authorization, the other electronic key 2 can obtain all or part of at least one electronic encryption key linked to and corresponding to the deletion encryption key of the original electronic key 2, but cannot obtain the same deletion encryption key as the original electronic key 2. Therefore, the other authorized electronic key 2 will never have the same deletion encryption key as the original electronic key 2, and will not be able to change the electronic lock 3 that has the same deletion encryption key as the original electronic key 2, nor will it be able to re-authorize another electronic key 2 to have the ability to control the electronic lock 3 that has the same deletion encryption key as the original electronic key 2.

[0047] In the verification mechanism of the deletion encryption key, the electronic key 2 is divided into two types, the main electronic key 2 and the slave electronic key 2, according to the deletion encryption key. After the pairing setting operation between the electronic key 2 and the electronic lock 3 is completed, both the electronic key 2 and the electronic lock 3 have the same deletion encryption key and pairing setting information including at least one electronic encryption key. When the electronic key 2 with the deletion encryption key performs the authorization operation for another electronic key 2, the electronic key 2 can only copy all or part of the at least one electronic encryption key associated with the same deletion encryption key to the other electronic key 2, but the deletion encryption key setting cannot be copied. The electronic key 2 with the same deletion encryption key as the electronic lock is the main electronic key 2 and is not authorized. If another authorized electronic key 2 does not have the same deletion encryption key as the electronic lock 3, it is defined as the slave electronic key 2 of the electronic lock 3. The slave electronic key 2 has the ability to control all or some of the electronic locks 3 that are associated with the same authorized deletion encryption key, but does not have the ability to re-authorize at least one electronic encryption key that is associated with the same deletion encryption key as the authorized electronic key 2 to another electronic key 2, nor does it have the ability to change or delete the pairing setting information of the electronic lock 3 that has the same deletion encryption key as the authorized electronic key 2. This is because the deletion encryption key is not copied to another electronic key 2 during authorization, and the authorization and change or deletion authority of the electronic key 2 is managed by the deletion encryption key.

[0048] The authorization operation of the electronic key 2 is described as follows: When the electronic key 2 is electrically connected to the slave electronic key 2, the electronic key 2 is connected to the first terminal 24 of another electronic key 2 via the first terminal 24, and the first process module 22 of the electronic key 2 copies all or part of at least one electronic encryption key stored in the first storage module 23 to the first storage module 23 of the slave electronic key 2. In this embodiment, the first terminals 24 of the electronic key and the slave electronic key are connected to each other via a transmission line, but this is not limited thereto. After connection, the electronic key 2 starts the authorization operation automatically or by pressing at least one button. In the encryption key deletion verification mechanism, the electronic key 2 is connected to the first terminal 24 of another electronic key 2 via the first terminal 24, and the first process module 22 of the electronic key 2 copies and stores all or part of at least one electronic encryption key associated with the deletion encryption key in the first storage module 23 in the first storage module 23 of the slave electronic key 2. The electronic key 2 can use at least one button to select the electronic lock 3 corresponding to all or part of the at least one electronic encryption key associated with the deletion encryption key to be authorized, thereby storing all or part of the corresponding at least one electronic encryption key to be authorized in the slave electronic key 2. The process of backing up and authorizing the electronic key 2 is simple and does not require computer setup.

[0049] In the deletion encryption key verification mechanism, when the electronic key 2 is also a slave electronic key 2 of another electronic key 2, all or part of at least one electronic encryption key associated with the deletion encryption key stored in the electronic key 2 is stored in the slave electronic key 2. The association of the deletion encryption key is defined as a correspondence between at least one electronic encryption key of the same set written in the first storage module 23 or the second storage module 33 and the written deletion encryption key during the pairing setting operation between the electronic key 2 and the electronic lock 3. In other words, in the deletion encryption key verification mechanism, at least one electronic encryption key stored in the electronic key 2 during pairing setting corresponds to the stored deletion encryption key, and the electronic key 2 has at least one electronic encryption key associated with the same deletion encryption key. When the electronic key 2 is also a slave electronic key 2 of another electronic key 2, the first storage module 23 of the electronic key 2 contains at least one electronic encryption key associated with the deletion encryption key and at least one electronic encryption key not associated with the deletion encryption key. Among these, at least one electronic encryption key that is linked to and corresponds to the deletion encryption key has the authority to authorize the slave electronic key 2, while at least one electronic encryption key that is not linked to the deletion encryption key does not have the authority to authorize other electronic keys 2. In the present invention, only the electronic key 2 that stores the deletion encryption key can have the ability to authorize other slave electronic keys 2, for example, through factory settings or reset settings of the editing management device. By pressing at least one button, the electronic key 2 can select all or some of the electronic locks 3 that have the same deletion encryption key that it wants to authorize, and store all or some of the corresponding at least one electronic encryption key in the slave electronic key 2. By managing the authorization authority through the design of the deletion encryption key, the authority of the electronic locks 3 can be effectively controlled and the authority of the electronic key 2 can be prevented from being abused.

[0050] When the first processing module 22 of the electronic key 2 is in authorization mode and receives and stores multiple sets of electronic encryption keys in the first storage module 23, if it detects that the same electronic encryption keys are present, the first processing module 22 of the electronic key 2 will not store the same electronic encryption keys in the first storage module 23 twice, thereby effectively saving space in the first storage module 23. When the storage space in the first storage module 23 is exhausted or about to be exhausted, or when the power of the power module 21 of the electronic key 2 falls below a threshold, the electronic key 2 will issue a warning signal, such as an LED indicator light or a buzzer sound, via an alarm module (not shown) to prompt the user to manually delete the electronic encryption keys in the first storage module 23 or replace the battery to maintain normal use of the electronic key 2.

[0051] When the pairing setting information includes at least one electronic encryption key, or when the pairing setting information includes both the deletion encryption key and at least one electronic encryption key during the verification mechanism of the deletion encryption key, the function of the electronic encryption key is to confirm the basis for locking or unlocking the electronic lock 3. The electronic encryption key is a random number generated by the first process module 22 or the second process module 32. The random number is designed to have at least four bytes, and each byte is 8 bits, so that there are 232 combinations of the random number. In another embodiment, the random number is designed in pairs, and there are 26 combinations of the random number. Because the number of combinations reaches four, the duplication rate of random numbers is very low, making them difficult to decipher and providing extremely high security. Both the electronic key 2 and the electronic lock 3 store electronic encryption keys. When the electronic encryption keys of the electronic lock 3 and the electronic key 2 match each other, the first process module 22 or the second process module 32 will automatically start up or issue a lock or unlock command, causing the power supply module 21 to supply power to the shape memory alloy unit of the lock cylinder module 31, which will activate the latch unit and lock or unlock the electronic lock 3. This eliminates the need for biometric identification and manual password entry and provides a high level of security.

[0052] When locking or unlocking the electronic lock 3 paired with the electronic key 2, the electronic key 2 and the electronic lock 3 are electrically connected via the first terminal 24 and the second terminal 34, and the first process module 22 or the second process module 32 transmits pairing setting information. When the receiving first process module 22 or the second process module 32 determines that the pairing setting information matches at least one electronic encryption key stored in the first storage module 23 or the second storage module 33, the power supply module 21 provides power to the lock cylinder module 31 of the connected electronic lock 3 and initiates the corresponding locking or unlocking operation. The match between at least one electronic encryption key of the electronic key 2 and the electronic lock 3 is defined as the same electronic encryption key or the same set of electronic encryption keys. If the pairing setting information transmitted and received between the electronic key 2 and the electronic lock 3 contains the same electronic encryption key, it is determined that they match. When the pairing setting information is set to include at least two or more electronic encryption keys of the same set, the pairing setting information exchanged between the electronic key 2 and the electronic lock 3 is determined to match if it contains the same set of electronic encryption keys. When the pairing setting information is set to include at least one pair of electronic encryption keys, the electronic key 2 and the electronic lock 3 can be determined to match only when they transmit one of the pair of electronic encryption keys in order and receive the other of the pair of electronic encryption keys correctly in order.

[0053] Between the electronic key 2 and the electronic lock 3, when the first process module 22 or the second process module 32 determines that at least one electronic encryption key stored in the electronic key 2 and the electronic lock 3 matches each other, it may start a locking or unlocking operation, automatically activate the electronic lock 3 from the original locked state to the unlocked state, or automatically activate the electronic lock 3 from the original unlocked state to the locked state, and may also send a locking command or an unlocking command between the electronic key 2 and the electronic lock 3. For example, when at least one electronic encryption key stored in the pairing setting information sent between the electronic key 2 and the electronic lock 3 matches each other, Upon dynamic activation or a lock or unlock command, the second process module 32 energizes and heats the shape memory alloy unit of the lock cylinder module 31 using power provided via the power module 21 of the electronic key 2. As the temperature of the shape memory alloy unit rises, the shape memory alloy unit deforms, thereby moving the latch unit between the locked and unlocked positions to lock or unlock the electronic lock 3. After the electronic lock 3 locks or unlocks, it sends a lock or unlock completion signal to the electronic key 2. After the electronic key 2 receives the lock or unlock completion signal, it alerts the user that the electronic lock 3 has been successfully locked or unlocked. If at least one electronic encryption key between the electronic key 2 and the electronic lock 3 does not match, the electronic lock 3 will not perform the lock or unlock operation.

[0054] In this embodiment, the pairing setting information between the electronic key 2 and the electronic lock 3 can be selectively set to a single electronic encryption key, multiple electronic encryption keys, or a pair of electronic encryption keys. When a single electronic encryption key is used, the electronic key 2 and the electronic lock 3 are connected via the first terminal 24 and the second terminal 34, the electronic key 2 supplies power to the electronic lock 3, and the pairing setting operation is initiated. During pairing, a random electronic encryption key is generated by the first process module 22 or the second process module 32 and stored in the first storage module 23 or the second storage module 33, respectively. The deletion encryption key is also copied from the first storage module 23 to the second storage module 33, so that both the electronic key 2 and the electronic lock 3 have the electronic encryption key and the deletion encryption key. When the electronic key 2 is to lock or unlock the electronic lock 3, the power supply module 21 supplies power to the electronic lock 3 through the connection between the first terminal 24 and the second terminal 34, starting up the electronic lock 3. After verifying whether the electronic key 2 and the pairing setting information match, the first process module 22 sends the pairing setting information including the electronic encryption key to the second process module 32. The second process module 32 receives the pairing setting information and determines whether it matches the electronic encryption key in the second storage module 33. If they match, the second process module 32 activates the corresponding locking or unlocking operation. The locking or unlocking operation may include the second process module 32 passing electricity through the shape memory alloy unit in the lock cylinder module 31 to heat it, and when the temperature of the shape memory alloy unit rises to a certain threshold, the shape memory alloy unit contracts and deforms, causing the latch unit to move between the locked position and the unlocked position, allowing the electronic lock 3 to achieve the locking or unlocking function, and when locking or unlocking is completed, the second process module 32 returns a signal indicating completion of locking or unlocking to the first process module 22, and after receiving the signal indicating completion of locking or unlocking, the first process module 22 activates the flashing indicator light of the electronic key 2 to notify the user of locking or unlocking.If the second process module 32 receives the electronic key and determines that it does not match the electronic encryption key stored in the second storage module 33, the electronic lock 3 will not lock or unlock. The pairing setup operation, pairing setup information verification, and locking or unlocking operation of the other electronic key 2 for the multiple electronic locks 3 are the same as those described above, and will not be described again here.

[0055] The pairing setting information between one electronic key 2 and one electronic lock 3 can be selectively set to include a single electronic encryption key, multiple electronic encryption keys, or a pair of electronic encryption keys. When the electronic key 2 wants to lock or unlock the electronic lock 3, the power supply module 21 supplies power to the electronic lock 3 through the connection between the first terminal 24 and the second terminal 34. After starting the electronic lock 3, the electronic key and the pairing setting information are mutually verified to be consistent with each other, and then the corresponding locking or unlocking operation is initiated. The second process module 32 transmits the pairing setting information, including at least one electronic encryption key, to the first process module 22. After receiving the pairing setting information, the first process module 22 The first process module 22 determines whether at least one electronic encryption key stored in the storage module 23 matches with the other. If they match, the first process module 22 sends a lock or unlock command to the second process module 32. When the second process module 32 receives the lock command, it starts the locking operation. When the second process module 32 receives the unlock command, it starts the unlocking operation. When the locking or unlocking operation is complete, the second process module 32 returns a lock or unlock completion signal to the first process module 22. After receiving the lock or unlock completion signal, the first process module 22 starts flashing the indicator light of the electronic key 2 to notify the user of the locking or unlocking operation. If the first process module 22 determines that the pairing setting information it receives does not match with at least one electronic encryption key stored in the first storage module 23, the electronic lock 3 does not perform the locking or unlocking operation. The pairing setting operation, pairing setting information verification, and locking or unlocking operation for one electronic key 2 with multiple electronic locks 3 are the same as those described above, so a repeated description will not be provided. Here, the electronic encryption key is not limited to a single, multiple, or paired embodiment, and the communication method between the electronic key 2 and the first process module 22 and the second process module 32 in the electronic lock 3 is not limited to the above. The above description is merely an example and is not intended to limit the present invention.

[0056] In other embodiments, if it is desired to improve the security of the electronic key 2 and the electronic lock 3, the pairing setting information may include multiple pairs of paired electronic encryption keys as a judgment condition, and judgment may be made by verifying multiple pairs of paired electronic encryption keys between the electronic key 2 and the electronic lock 3 until a predetermined number of pairs of paired electronic encryption keys are satisfied, or the electronic lock 3 may perform the corresponding locking or unlocking operation only after completing the comparison judgment of all pairs of paired electronic encryption keys stored.

[0057] In the mechanism for verifying the deletion key, if a user needs to change the electronic encryption key of the electronic key 2 or the electronic lock 3, for example, if the slave electronic key 2 is lost or stolen, or if the electronic lock 3 is suspected of being illegally unlocked, the electronic encryption key can be changed or deleted at any time. For example, to reset the electronic encryption key or deletion key of the electronic lock 3 and change or delete the pairing setting information of the electronic lock 3, it is necessary to connect it to the electronic key 2 having the same deletion key. The electronic key 2 and the electronic lock 3 are electrically connected via the first terminal 24 and the second terminal 34. The user can activate the change or deletion mechanism of the electronic lock 3 by, for example, long pressing the button on the electronic key 2. For example, by lighting up different colors, the first process module 22 or the second process module 32 determines that the deletion keys of the electronic key 2 and the electronic lock 3 are the same, and the first process module 22 or the second process module 32 stores the same deletion key in the electronic lock 3. When it is necessary to change or delete the deletion encryption key and at least one electronic encryption key stored in the electronic lock 3, the first process module 22 and the second process module 32 communicate with each other via the connection between the first terminal 24 and the second terminal 34. The first process module 22 or the second process module 32 determines whether the deletion encryption key stored in the electronic key 2 is the same as the deletion encryption key stored in the electronic lock 3. If the deletion encryption keys of the electronic key 2 and the electronic lock 3 are the same, the first process module 22 or the second process module 32 issues a change or deletion command to change or delete the deletion encryption key and the electronic encryption key in the second storage module 33. If the deletion encryption keys of the electronic key 2 and the electronic lock 3 are different, no operation is performed. By setting the deletion encryption key, the authority to change or delete the electronic encryption keys of the electronic key 2 and the electronic lock 3 is effectively managed, and the electronic lock 3 and the electronic key 2 are provided with better safety in use.

[0058] In the encryption key erasure verification mechanism, if the pairing setting information in the second storage module 33 is deleted or changed and the electronic lock 3 no longer has the encryption key erasure and electronic key settings, any electronic key 2 can connect to the electronic lock 3 and perform the pairing setting operation again. At least one electronic key will be generated by the first processing module 22 or the second processing module 32, and then the at least one electronic key will be stored in the first storage module 23 or the second storage module 33, respectively. The encryption key of the electronic key 2 will be written to the second storage module 33, and the encryption key erasure and at least one electronic key in the electronic lock 3 will be reset. The change of the encryption key erasure and at least one electronic key erasure enhances the security of the electronic lock 3. Even if the electronic key 2 is lost, the pairing setting information of the electronic lock 3 can be quickly replaced, ensuring the protection of the electronic lock 3.

[0059] Referring to FIG. 4, in the verification mechanism of the deletion encryption key, the electronic key and electronic lock system 10 further includes an editing management device 4, which may be a computer or a tablet, and is used to set, delete, or change the deletion encryption key or at least one electronic encryption key stored in the electronic key 2 or the electronic lock 3. The editing management device can also directly set, delete, or change the deletion encryption key or at least one electronic encryption key for the electronic key or the electronic lock according to the selected function. If the editing management device is matched with the electronic key or the electronic lock, it can set, delete, or change the deletion encryption key or at least one electronic encryption key for the deletion encryption key and electronic encryption key of the electronic key or the electronic lock. The editing management device 4 may be, for example, a computer, a handheld device, or a device with computing capabilities. Referring to FIG. 5 , the editing management device 4 includes a third terminal 44, a third processing module 42, a third storage module 43, and an I / O module 41. The third processing module 42 connects to the third terminal 44 and the third storage module 43. The third terminal 44 connects to the first terminal 24 or the second terminal 34 and is used to transmit the setting information of the erasure encryption key. The third terminal 44 is, for example, a USB, Thunderbolt, or RS-232 transmission interface. The third storage module 43 is, for example, a storage device such as a memory or a hard disk. The third processing module 42 is, for example, a central processing unit or a microprocessor.

[0060] In the deletion encryption key verification mechanism, if the electronic key 2 wants to delete or change the deletion encryption key, it needs to perform the deletion encryption key setting operation via the editing management device 4. That is, the electronic key 2 and the editing management device 4 communicate with the first process module 22 and the third process module 42 via the connection between the first terminal 24 and the third terminal 44. The user can operate the editing management device 4, for example, by selecting a delete command via the I / O module 41 or inputting and writing the deletion encryption key setting information. The editing management device 4 will then delete or change the deletion encryption key or at least one electronic encryption key for the electronic key 2, returning the electronic key 2 to an unlinked state or a state in which a new deletion encryption key has been written, thereby completing the deletion encryption key setting operation. The first process module 22 and the third process module 42 can also delete or change the deletion encryption key or at least one electronic encryption key of the electronic key 2 only through the deletion encryption key verification mechanism. For example, the setting information of the deletion encryption key input by the user through the I / O module 41 is compared with the deletion encryption key stored in the first storage module 23. The input deletion encryption key is transmitted between the third process module 42 and the first process module 22. If the third process module 42 or the first process module 22 compares the deletion encryption keys and determines that they are the same deletion encryption key, the first process module 22 or the third process module 42 deletes or changes the first storage module 23. The deletion encryption key and all electronic encryption keys or at least one electronic encryption key linked to the deletion encryption key in the storage module 23 are deleted, and the user again inputs a new deletion encryption key through the I / O module 41. The third process module 42 writes the new deletion encryption key into the first storage module 23, and performs pairing setting operation for the electronic lock 3 using the new deletion encryption key. Furthermore, when the electronic key 2 deletes or changes the deletion encryption key, it is necessary to first delete the setting information of the same deletion encryption key from the linked electronic lock 3, thereby avoiding the situation where the electronic key 2 cannot make changes to the linked electronic lock 3 after changing the deletion encryption key of the electronic key 2.

[0061] In addition, in the verification mechanism of the deletion encryption key, if the electronic key 2 is lost, the editing management device 4 can also delete or change the deletion encryption key or at least one electronic encryption key of the electronic lock 3. The editing management device 4 and the electronic lock 3 are connected via the third terminal 44 and the second terminal 34, and the third process module 42 and the second process module 32 communicate with each other. The user operates the editing management device 4 to make the editing management device 4 delete or change the deletion encryption key for the electronic lock 3. Then, the second process module 32 and the third process module 42 can delete or change the deletion encryption key and at least one electronic encryption key of the electronic key 2 only through the verification mechanism of the deletion encryption key. For example, the setting information of the deletion encryption key input by the user via the I / O module 41 is compared with the deletion encryption key stored in the second storage module 33, and the input deletion encryption key is transmitted between the third process module 42 and the second process module 32. If the third process module 42 or the second process module 32 compares the deletion encryption key and determines that they are the same deletion encryption key, the second process module 32 or the third process module 42 deletes or changes the deletion encryption key or at least one electronic encryption key in the second storage module 33, and the editing management device 4 can reset the electronic lock 3 in addition to the electronic key 2.

[0062] The electronic key 2 and electronic lock 3 disclosed in the present invention are designed to generate at least one randomly generated electronic encryption key through a pairing mechanism. By adopting the concept of matching electronic encryption keys between the electronic key 2 and the electronic lock 3, the traditional complex encryption and decryption process can be omitted, avoiding the need for extensive and complex calculations and the need for high-performance hardware and storage space. The electronic key 2 uses a digitized electronic encryption key to replace a traditional physical key. The memory space size of the first storage module 23 can be tailored to suit individual needs. The electronic key 2 can store hundreds, even thousands, of electronic locks, allowing a single electronic key 2 to lock and unlock such a large number of electronic locks. Compared to traditional locking tools, this eliminates the need to manufacture and carry a large number of keys, resulting in greater convenience and significantly reduced hardware costs.

[0063] The electronic key 2 and the electronic lock 3 are physically connected by simple means, and at least one electronic encryption key is generated by random numbers to complete the pairing setting information. The number of possible combinations of the electronic encryption keys can reach billions. According to the law of large numbers, the probability of duplicate electronic encryption keys being used is extremely low. Even in the face of a brute-force computer attack, cracking remains difficult. Compared to conventional physical keys, which only have hundreds or thousands of possible combinations and whose structures are exposed, making them easy to copy or crack, and compared to information transmitted via commercially available wireless signals, which is easily intercepted, the electronic encryption key of the present invention cannot be spied on or known. The electronic key 2 and the electronic lock 3 are physically docked to transmit pairing setting information including at least one electronic encryption key, making the possibility of skimming or cracking extremely small. As a result, the electronic lock 3 of the present invention has a fairly high level of security.

[0064] In addition, the verification mechanism of the deletion encryption key can be used for authority management between the electronic key 2 and the electronic lock 3 of the present invention. When the electronic key 2 has the deletion encryption key, it will not authorize another electronic key 2 to control the electronic lock 3 associated with the deletion encryption key, or change the setting information stored in the electronic lock 3 associated with the deletion encryption key. As a result, if the authorized electronic key 2 does not have the same deletion encryption key, it will not be able to re-authorize the control of the electronic lock 3 associated with the same deletion encryption key to another electronic key 2, nor will it have the authority to change the electronic lock 3. The verification mechanism of the deletion encryption key can effectively manage the control authority of the electronic lock 3, preventing an unlimited number of electronic keys 2 from being re-authorized or the setting information of the electronic lock 3 from being changed, and maintaining the control authority of the same deletion encryption key between the electronic key 2 and the electronic lock 3.

[0065] The lock cylinder module 31 of the electronic lock 3 adopts a shape memory alloy unit design. After heating, the length of the shape memory alloy unit is shortened and the latch unit is pulled, achieving the locking or unlocking function with a simple structural design. The power required by the electronic lock 3 is provided by the electronic key 2, and the electronic lock 3 does not require a power supply to be installed. The structure of the lock cylinder module 31 is very simple, with the advantages of low cost and a simple manufacturing process. The design of the electronic key 2 and electronic lock 3 of the present invention has the advantages of high reliability and better adaptability.

[0066] As described above, this invention has been disclosed by way of an embodiment, but of course, this is not intended to limit this invention. As can be easily understood by a person skilled in the art, appropriate changes and modifications can naturally be made within the scope of the technical idea of ​​this invention, and therefore the scope of patent protection must be determined based on the scope of the claims and the equivalents thereto.
