[0046] The main control module 300 is electrically connected to the motor driving module 400, and is used to generate a motor driving signal according to the first touch signal and the first preset signal;

[0047] The second touch keyboard 200 and the first touch keyboard 100 are independently powered; the second touch keyboard 200 is electrically connected to the main control module 300, and is used to generate a second touch signal in response to a second input instruction when the first touch keyboard 100 is in an abnormal state, and transmit the second touch signal to the main control module 300; the area of ​​the second touch keyboard 200 is smaller than that of the first touch keyboard 100;

[0048] The main control module 300 is further used to generate a motor driving signal according to the second touch signal and the second preset signal;

[0049] The motor driving module 400 is used to control the lock tongue to be in an unlocked state or a locked state according to the motor driving signal.

[0050] Among them, the state of the first touch keyboard 100 includes a normal state and an abnormal state; among them, the normal state refers to the situation where the power supply of the first touch keyboard 100 is normal and there is no other damage; the abnormal state refers to the situation where the first touch keyboard 100 is unavailable due to abnormal reasons, wherein the abnormal reasons include but are not limited to power outage, power supply failure, insufficient power supply, and damage; when the first touch keyboard 100 is in a normal state, it can respond to a first input instruction and generate a first touch signal; wherein the first input instruction refers to a character combination input by touch or pressure sensing, wherein the form or number of the character combination is not limited herein; the first touch signal refers to the corresponding electrical signal generated by the first touch keyboard 100 in response to the first input instruction.

[0051] The second touch keyboard 200 includes a hidden mode and a standby mode; the hidden mode means that the second touch keyboard 200 is in a power-off state; the standby mode means that when the first touch keyboard 100 is in an abnormal state, the second touch keyboard 200 is activated so that the second touch keyboard 200 can take over the input work, that is, generate a second touch signal in response to a second input instruction; the second input instruction refers to a character combination input by touch or pressure sensing, wherein the form or number of the character combination is not limited here; the second touch signal refers to the corresponding electrical signal generated by the second touch keyboard 200 in response to the second input instruction. It can be understood that when the first touch keyboard 100 is in a normal state, the second touch keyboard 200 is in a hidden mode, that is, the second touch keyboard 200 is in a power-off state; when the first touch keyboard 100 is in an abnormal state, the second touch keyboard 200 is in a standby mode and can take over the input work.

[0052] It should be noted that the first touch keyboard 100 and the second touch keyboard 200 are arranged on the same lock panel of the electronic password lock, and the area of ​​the second touch keyboard 200 is smaller than that of the first touch keyboard 100, so as to reduce the space occupied by the second touch keyboard 200 as much as possible, reserve more space for further improvement of the electronic password lock, and ensure that the impact of the second touch keyboard 200 on the layout of other components on the electronic password lock is minimized to the greatest extent, where other components include but are not limited to fingerprint recognition module, IC card sensor, doorbell, face recognition module.

[0053] Among them, the main control module 300 includes a main control chip, which is used to generate a motor drive signal according to the first touch signal and the first preset signal, or according to the second touch signal and the second preset signal; wherein, the model of the main control chip needs to be selected according to the actual application scenario, and the embodiment of the present application does not make any specific limitation; the first preset signal and the second preset signal refer to a user-defined preset character combination, that is, a password; the character length corresponding to the first preset signal and the character length corresponding to the second preset signal are not specifically limited in the embodiment of the present application; it should be noted that the first preset signal and the second preset signal can be the same or different, and need to be set according to the actual needs of the user, which is not limited here; the motor drive signal can be but is not limited to a pulse width modulation signal.

[0054] Optionally, the main control module 300 also includes a first main control module and a second main control module, which are independently powered and operate independently; wherein the first main control module is electrically connected to the first touch keyboard 100 and the motor drive module 400, respectively, and is used to generate a motor drive signal according to the first touch signal and the first preset signal; the second main control module is electrically connected to the second touch keyboard 200 and the motor drive module 400, respectively, and is used to generate a motor drive signal according to the first touch signal and the first preset signal when the first touch keyboard 100 is in an abnormal state.

[0055] Among them, the motor drive module 400 includes a motor, and the model or type of the motor needs to be set according to the actual application scenario, and the embodiment of the present application does not make specific restrictions; the motor drive module 400 can control the motor to rotate forward or reverse or stop according to the motor drive signal, and then control the lock tongue to be unlocked or locked; wherein the lock tongue can be but not limited to a square tongue to ensure the security of the electronic password lock; the lock tongue is in the unlocked state, which means that the lock tongue can be separated from the lock slot, and the electronic password lock is in the unlocked state; the lock tongue is in the locked state, which means that the lock tongue is locked in the lock slot and cannot be separated from the lock slot, and the electronic password lock is in the locked state. It should be noted that when the lock tongue is in the unlocked state, the way in which the lock tongue is separated from the lock slot can be but not limited to automatic control mode and manual control mode, which needs to be set according to the actual application scenario, and is not specifically limited here; wherein the manual control mode can be but not limited to controlling the lock tongue to be separated from the lock slot by turning the handle.

[0056] For example, assume that the electronic password lock is in a locked state, that is, the lock tongue is in a locked state; when the first touch keyboard 100 is in a normal state, the second touch keyboard 200 is in a hidden mode, and the user inputs a first input instruction, that is, a character combination, to the first touch keyboard 100 by touch. The first touch keyboard 100 responds to the first input instruction, generates a first touch signal, and transmits it to the main control module 300. The main control module 300 compares the first touch signal with the first preset signal; if the first touch signal matches the first preset signal, the main control module 300 generates a motor drive signal and transmits it to the motor drive module 400. The motor drive module 400 controls the lock tongue to be in an unlocked state according to the motor drive signal; if the first touch signal does not match the first preset signal, the main control module 300 generates a corresponding motor drive signal. At this time, the motor drive module 400 controls the lock tongue to remain in a locked state according to the motor drive signal. When the first touch keyboard 100 is in an abnormal state, the second touch keyboard 200 is in a standby mode. The user inputs a second input instruction, i.e., a character combination, to the second touch keyboard 200 by touch. The second touch keyboard 200 responds to the second input instruction, generates a second touch signal, and transmits it to the main control module 300. The main control module 300 compares the second touch signal with the second preset signal. If the second touch signal matches the second preset signal, the main control module 300 generates a motor drive signal and transmits it to the motor drive module 400. The motor drive module 400 controls the lock tongue to be in an unlocked state according to the motor drive signal. If the second touch signal does not match the second preset signal, the main control module 300 generates a corresponding motor drive signal. At this time, the motor drive module 400 controls the lock tongue to remain in a locked state according to the motor drive signal.

[0057] In this embodiment, based on the second touch keyboard 200, when the first touch keyboard 100 is in an abnormal state, i.e., insufficient power supply, power outage, or damage, etc., it can take over the input work to ensure the availability of the electronic password lock, effectively prevent the problem of failure of the electronic password lock due to abnormal reasons such as insufficient power supply, power outage, or damage to the first touch keyboard 100, and further improve the reliability of the electronic password lock; at the same time, based on the second touch keyboard 200, it can completely avoid the security risks and the problem of easy loss of keys brought about by using traditional physical key locks as backup unlocking methods; and, reducing the area of ​​the second touch keyboard 200 can effectively reduce the space occupied by the second touch keyboard 200, reserve more space for further improvement of the electronic password lock, and minimize the impact of the second touch keyboard 200 on the layout of other components on the electronic password lock.

[0058] In one embodiment, see Figure 2 , the first touch keyboard 100 includes a first number of first touch keys;

[0059] The second touch keyboard 200 includes a second number of second touch keys;

[0060] The first number is greater than the second number.

[0061] Preferably, the first touch keyboard 100 and the second touch keyboard 200 are integrally formed.

[0062] Preferably, the character corresponding to the second touch key is partially identical to the character corresponding to the first touch key.

[0063] Preferably, the first touch keyboard 100 includes 12 first touch keys;

[0064] The second touch keyboard 200 includes three second touch keys.

[0065] Preferably, the 12 first touch keys are arranged in 4 rows and 3 columns;

[0066] 3 second touch keys, arranged in 1 row and 3 columns.

[0067] Among them, the first number is greater than the second number to ensure that the space occupied by the second touch keyboard 200 is smaller, further reducing the impact of the second touch keyboard 200 on the layout of other components on the electronic password lock; the first touch key is electrically connected to the main control module 300 for generating a first touch signal; the second touch key is electrically connected to the main control module 300 for generating a second touch signal; it should be noted that the shape or style of the first touch key and the second touch key is not specifically limited in the embodiment of the present application.

[0068] It can be understood that the first number and arrangement of the first touch keys corresponding to the first touch keyboard 100 can be set according to the actual application and / or actual situation of the electronic password lock, and will not be elaborated here; similarly, the second number and arrangement of the second touch keys corresponding to the second touch keyboard 200 can also be set according to the actual application and / or actual situation of the electronic password lock, and will not be elaborated here.

[0069] For example, the first touch keyboard 100 and the second touch keyboard 200 are integrally formed and arranged on the surface of the lock panel of the electronic password lock, so that the user can input the first input instruction by touching the first touch key, and then generate a first touch signal according to the first input instruction; or, touch the second touch key to input the second input instruction, and then generate a second touch signal according to the second input instruction; it should be noted that the second touch key can only be powered on and used when the first touch key is abnormal, wherein the cause of the abnormality of the first touch key may be but is not limited to insufficient power supply, power outage, and damage. Optionally, in actual applications, after the user uses the first touch keyboard 100 to input the first input instruction, there is no need to press or touch an additional unlock key to confirm that the password input is completed, and a first touch signal can be directly generated; and when the first touch signal matches the first preset signal, the lock tongue can be directly controlled to an unlocked state through the motor drive module 400; similarly, when the first touch keyboard 100 is abnormal, after the user uses the second touch keyboard 200 to input the second input instruction, there is no need to press or touch an additional unlock key to confirm that the password input is completed, and a second touch signal can be directly generated; and when the second touch signal matches the second preset signal, the lock tongue can be directly controlled to an unlocked state through the motor drive module 400; it should be noted that whether it is necessary to set an additional unlock key to confirm that the password input is completed needs to be selected according to the actual application scenario and is not limited here.

[0070] In this embodiment, based on a first number of first touch keys and a second number of second touch keys, a foundation is laid for generating a first touch signal and a second touch signal; and setting the second number to be smaller than the first number can further ensure that the second touch keyboard 200 occupies a smaller space, so as to further reduce the impact of the second touch keyboard 200 on the layout of other components on the electronic password lock.

[0071] In one embodiment, see Figure 3 , the electronic password lock further includes: a first power supply 500 and a second power supply 600;

[0072] The first power supply 500 is electrically connected to the first touch keyboard 100 and is used to provide a power supply voltage to the first touch keyboard 100;

[0073] The second power supply 600 is electrically connected to the second touch keyboard 200 , and is used to provide a power supply voltage to the second touch keyboard 200 .

[0074] Preferably, the first power supply 500 is electrically connected to the main control module 300 and the motor drive module 400 respectively, and is also used to provide power supply voltage to the main control module 300 and the motor drive module 400 .

[0075] Among them, the first power supply 500 and the second power supply 600 are independent of each other and both belong to the internal power supply of the electronic password lock; optionally, the first power supply 500 can be but not limited to a battery or a dry cell; the second power supply 600 can be but not limited to a battery or a dry cell.

[0076] In this embodiment, based on the first power supply 500 and the second power supply 600, the stability of the power supply of the electronic combination lock can be ensured, and the reliability of the electronic combination lock is further improved.

[0077] In one embodiment, see Figure 4 , the electronic password lock further includes: a third power supply 700 and a power supply interface 800;

[0078] The third power supply 700 is electrically connected to the first touch keyboard 100 and is used to provide a power supply voltage to the first touch keyboard 100;

[0079] The power supply interface 800 is electrically connected to the second touch keyboard 200 and is used to access the external power supply 900 . When the third power supply 700 is abnormal, the external power supply 900 provides the second touch keyboard 200 with a power supply voltage.

[0080] Preferably, the third power supply 700 is electrically connected to the main control module 300 and the motor drive module 400 respectively, and is also used to provide a power supply voltage to the main control module 300 and the motor drive module 400;

[0081] The power supply interface 800 is electrically connected to the main control module 300 and the motor drive module 400 respectively, and is also used to provide power supply voltage to the main control module 300 and the motor drive module 400 through the external power supply 900 when the third power supply 700 is abnormal.

[0082] Among them, the power supply interface 800 can be but is not limited to a wired charging interface or a wireless charging interface; the external power supply 900 can be any power supply that can ensure the normal operation of the second touch keyboard 200, the main control module 300 and the motor drive module 400, and is not limited here.

[0083] For example, when the third power supply 700 is normal, that is, the power supply is sufficient, the third power supply 700 is used to supply power to the first touch keyboard 100, the main control module 300 and the motor drive module 400 to ensure that the first touch keyboard 100 is in a normal state, and to ensure that the main control module 300 and the motor drive module 400 remain in a normal working state; when the third power supply 700 is abnormal, that is, the power supply is insufficient or the power is off, the second power supply 600 is used to supply power to the second touch keyboard 200, the main control module 300 and the motor drive module 400 to ensure that the second touch keyboard 200 enters a standby mode, and to ensure that the main control module 300 and the motor drive module 400 continue to maintain a normal working state.

[0084] In this embodiment, when the third power supply 700 is abnormal, that is, the power supply is insufficient or the power is cut off, the external power supply 900 is connected through the power supply interface 800, and the external power supply 900 provides a stable power supply to the second touch keyboard 200, the main control module 300 and the motor drive module 400 respectively, thereby further improving the reliability of the electronic password lock.

[0085] In a specific embodiment, optionally, the electronic password lock also includes a fourth power supply; wherein the fourth power supply may be, but is not limited to, a storage battery or a dry cell, and the fourth power supply is an internal power supply of the electronic password lock; the fourth power supply is electrically connected to the main control module 300 and the motor drive module 400, respectively, and is used to provide a power supply voltage to the main control module 300 and the motor drive module 400; it can be understood that the fourth power supply is independent of the first power supply 500 or the third power supply 700, and both are arranged inside the electronic password lock; it can also be understood that the main control module 300 and the motor drive module 400 are independently powered by the first touch keyboard 100; the capacity of the fourth power supply can be set according to actual conditions, and it is only necessary to ensure that the normal operating voltage can be provided to the main control module 300 and the motor drive module 400.

[0086] In a specific embodiment, the electronic password lock also includes a low power alarm module; the low power alarm module is used to issue an alarm prompt when the first power supply 500 or the third power supply 700 is abnormal, that is, when the power supply is insufficient or the power is cut off, to remind the user that the power of the first power supply 500 or the third power supply 700 is abnormal, so as to take timely action.

[0087] In a specific embodiment, optionally, the electronic password lock also includes other components, including but not limited to a fingerprint recognition module, an IC card sensor, a doorbell, and a face recognition module, which are used to functionalize the electronic password lock and enrich the unlocking methods of the electronic password lock to further expand the application scope of the electronic password lock.

[0088] The above-mentioned electronic password lock, on the one hand, can take over the input work when the first touch keyboard 100 is in an abnormal state, i.e., insufficient power supply, power outage or damage, based on the second touch keyboard 200, so as to ensure the availability of the electronic password lock, and effectively prevent the problem of failure of the electronic password lock due to abnormal reasons such as insufficient power supply, power outage or damage of the first touch keyboard 100, thereby further improving the reliability of the electronic password lock; at the same time, based on the second touch keyboard 200, it is possible to completely avoid the security risks and the problem of easy loss of keys brought about by using traditional physical key locks as a backup unlocking method; and, reducing the area of ​​the second touch keyboard 200 can effectively reduce the space occupied by the second touch keyboard 200, reserve more space for further improvement of the electronic password lock, and minimize the influence of the second touch keyboard 200 on the layout of other components on the electronic password lock. On the second hand, based on the first number of first touch keys and the second number of second touch keys, a foundation is laid for generating the first touch signal and the second touch signal; and by setting the second number to be less than the first number, it can further ensure that the second touch keyboard 200 occupies a smaller space, so as to further reduce the influence of the second touch keyboard 200 on the layout of other components on the electronic password lock. On the third hand, based on the first power supply 500 and the second power supply 600, the stability of the power supply of the electronic password lock can be ensured, and the reliability of the electronic password lock is further improved. On the fourth hand, when the third power supply 700 is abnormal, that is, the power supply is insufficient or the power is cut off, the external power supply 900 is connected through the power supply interface 800, and the stable power supply is provided to the second touch keyboard 200, the main control module 300 and the motor drive module 400 respectively through the external power supply 900, which further improves the reliability of the electronic password lock.
