Description

Technical Field

[0001] This invention relates to electronic combination locks, and more particularly to a combination protection device and an electronic lock having the device. Background Technology

[0002] A combination lock is a device that controls the opening and closing of a lock by entering a password. It is widely used in various security fields, such as access control systems, safes, and automobiles. While traditional mechanical locks have a simple structure, they offer lower security and are easily pried open or have their keys copied. With technological advancements, combination locks have gradually replaced traditional mechanical locks, providing significantly higher security.

[0003] Traditional mechanical combination locks rely on a series of dials or buttons to set and input the password, while modern combination locks mostly use electronic technology, allowing users to input the password via a keypad and verify its correctness through a microprocessor. Combination locks offer advantages such as ease of operation, high security, and ease of password modification, making them suitable for various settings including homes, offices, and bank vaults.

[0004] Modern combination locks offer various input methods, such as keypad, touchscreen, and rotary dial. Keypad input is the most common, where users enter the password by pressing the number keys. Touchscreen input involves touching numbers or patterns on the screen. Rotary input involves rotating a dial to enter the password.

[0005] However, regardless of whether a combination lock uses a button, touchscreen, or rotary design, it must be equipped with an input device such as a numeric keypad, touchscreen, or keypad. These input devices typically require a relatively large space for users to easily enter their passwords. This requirement is particularly prominent in situations with limited space, such as smaller locks or other devices that require locking or unlocking operations, where applying traditional combination locks becomes quite difficult.

[0006] To address this issue, several innovative password input methods have emerged in recent years, attempting to reduce space usage while maintaining security. For example, biometric-based locks are gaining popularity, with fingerprint, facial recognition, and iris scanning technologies widely used in electronic locks. These technologies eliminate the need for traditional physical input devices, requiring only the user's physical characteristics for authentication, thus significantly saving space. Furthermore, some new locks employ voice or gesture recognition technologies, unlocking via voice commands or specific hand gestures. This approach not only saves surface space but also enhances user convenience and intelligence. However, these emerging technologies also face challenges, such as recognition accuracy, environmental adaptability, and cost, requiring further optimization and refinement. Summary of the Invention

[0007] The core objective of this invention is to propose and design an innovative password protection device. The main function and purpose of this device is to solve and overcome a series of problems and challenges faced in the application of password locks in the current market.

[0008] To achieve this goal, according to one aspect of the present invention, a password protection device is provided, including a control circuit board and a button connected to the control circuit board. The control circuit board has a pre-stored signal bundle. Multiple operation of the button can output a corresponding temporary signal bundle to the control circuit board. The control circuit board compares the temporary signal bundle with the signal bundle, and unlocks the state if and only if the two match.

[0009] The password protection device employing the above technical solution allows users to unlock the device by simply pressing a button and entering a password. Through its unique structural design and advanced technology, the device effectively reduces reliance on physical space while improving the convenience and security of password input. Furthermore, this invention emphasizes compatibility across different usage scenarios, ensuring its flexibility in adapting to the needs of various devices and environments.

[0010] Furthermore, the button is a switch button, which outputs a switch signal to the control circuit board. The switch signal output design is ingenious, effectively reducing the probability of accidental operation while ensuring signal transmission stability. To further enhance the user experience, the tactile feedback of the switch button has been specially optimized to ensure accurate operational feedback in various environments. In addition, the button is dustproof and waterproof to adapt to complex and varied real-world usage scenarios, further enhancing the device's durability and reliability. This design not only simplifies the user's interaction with the device but also significantly reduces the risk of malfunctions caused by external factors.

[0011] Specifically, the temporary signal bundle includes a segment of switch signals with specific rules. This temporary signal bundle is a digital signal and can be output by a switch button through a specific operation method. Each button press outputs a 0 or 1 signal to the control circuit board. This design enables users to input complex information with simple button operations, significantly improving password unlocking efficiency. Simultaneously, the digital nature of the temporary signal bundle ensures the accuracy of information transmission, effectively avoiding errors that may be caused by analog signals. To further enhance security, the device introduces a time mechanism, embedding the time information of each button press into the signal, thus effectively resisting replay attacks. Furthermore, the control circuit board's signal parsing process has been optimized, enabling it to complete the verification and processing of input signals in a very short time, ensuring real-time device response. This series of innovative designs not only improves system reliability but also provides users with a smoother operating experience.

[0012] Furthermore, the operation method includes at least one step: repeatedly outputting a specific number of 0 or 1 signals to the control circuit board by pressing a switch button within a set time period. In designing the operation method, the device fully considers the balance between simplicity and flexibility, ensuring that the complexity of the operation steps can be flexibly adjusted according to actual needs. For example, within a preset time range, the user can generate different signal combinations by pressing the button at different intervals, thereby achieving diverse password input modes. This mechanism significantly enhances password strength.

[0013] Furthermore, the operation method includes multiple sequential operation steps. The control circuit board compares the temporary signal bundle output by the next operation step with the temporary signal bundle preset by the control circuit only if the temporary signal bundle output by the previous operation step matches the corresponding signal bundle preset by the control circuit. The control circuit board has intelligent recognition capabilities, which can accurately distinguish the signal sequences corresponding to different operation steps and efficiently convert them into valid unlocking commands, further improving the system's adaptability and intelligence.

[0014] Preferably, the number of 0 or 1 signals output by the switch button to the control circuit board within the time set in each operation step is different.

[0015] In some implementations, an indicator light is also included to show whether the locked state is unlocked or not.

[0016] Preferably, after a certain operation step is performed, the indicator light also indicates whether the operation step matches the corresponding signal bundle preset by the control circuit. If the match is successful, the indicator light will turn green, prompting the user to continue to the next operation; if the match fails, the indicator light will turn red and flash briefly to remind the user to recheck the current operation step. This instant feedback mechanism not only effectively reduces user errors but also significantly improves the intuitiveness and convenience of the operation process.

[0017] According to another aspect of the present invention, an electronic lock is provided, which internally incorporates the aforementioned password protection device. The electronic lock unlocks only when a temporary signal bundle matches the actual signal bundle. This electronic lock utilizes the above-described technical solution to achieve the function of completing password input and unlocking with a single button. The device has a unique and advanced design, significantly reducing the physical space requirements and enhancing the convenience and security of password input. Furthermore, the present invention fully considers compatibility with different usage environments, ensuring that the device can adapt to the needs of various devices and environments.

[0018] Furthermore, it includes an indicator light to show the electronic lock's locked status or, after an unlocking operation via a button, to indicate whether the unlocking operation matches the corresponding preset signal bundle in the control circuit. The indicator light is designed with user habits in mind, using different colors and flashing patterns to convey information. Under normal conditions, the indicator light maintains a stable color to indicate that the device is in standby or locked state. When the user performs an unlocking operation, the indicator light responds immediately based on the matching result, providing clear visual feedback to the user. This design not only enhances the user experience but also further strengthens the device's security, ensuring that every operation is accurately communicated to the user.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Figure 1 and Figure 2 A combination lock according to one embodiment of the present invention is illustrated schematically.

[0023] As shown in the figure, the device includes a control circuit board 1 and a switch button 2 connected to the control circuit board 1. The control circuit board 1 has a pre-stored signal bundle. Multiple operations of the switch button 2 can output a corresponding temporary signal bundle to the control circuit board 1. The control circuit board 1 compares the temporary signal bundle with the signal bundle, and unlocks the state if and only if the two match.

[0024] The device also includes an indicator light 3 to display whether the lock is unlocked or not. Indicator light 3 is connected to the control circuit board 1, and its operation is controlled by the control circuit board 1. Indicator light 1 displays the locked state of the electronic lock, or, after an unlocking operation via the switch button 2, indicates whether the unlocking operation matches the corresponding preset signal bundle of the control circuit 1. The design of indicator light 3 takes into account user habits, conveying information through different colors and flashing patterns. Under normal conditions, indicator light 3 maintains a stable color to indicate that the device is in standby or locked state. When the user performs an unlocking operation, indicator light 3 responds immediately based on the matching result, providing the user with clear visual feedback. This design not only enhances the user experience but also further strengthens the security of the device, ensuring that every operation is accurately communicated to the user.

[0025] The password protection device employing the above technical solution allows users to unlock the device by simply pressing a button and entering a password. Through its unique structural design and advanced technology, the device effectively reduces reliance on physical space while improving the convenience and security of password input. Furthermore, this invention emphasizes compatibility across different usage scenarios, ensuring its flexibility in adapting to the needs of various devices and environments.

[0026] To further enhance the user experience, the tactile feedback of switch button 2 has been specially optimized to ensure accurate operation feedback in various environments. Furthermore, switch button 2 is dustproof and waterproof to adapt to complex and varied real-world usage scenarios, further enhancing the durability and reliability of the electronic lock. This design not only simplifies the user's interaction with the device but also significantly reduces the risk of malfunctions caused by external factors.

[0027] The temporary signal bundle comprises a specific set of switching signals. This bundle is a digital signal and can be output by switch button 2 through a specific operation method. Each operation of switch button 2 outputs a 0 or 1 signal to control circuit board 1. The ingenious design of the switching signal output effectively reduces the probability of misoperation while ensuring the stability of signal transmission. This design enables users to input complex information with simple button operations, significantly improving password unlocking efficiency. Simultaneously, the digital characteristics of the temporary signal bundle ensure the accuracy of information transmission, effectively avoiding errors that may be caused by analog signals. To further enhance security, the device introduces a time mechanism, embedding the time information of each button operation into the signal, thereby effectively resisting replay attacks. Furthermore, the control circuit board's signal parsing process has been optimized, enabling it to complete the verification and processing of input signals in a very short time, ensuring real-time device response. This series of innovative designs not only improves system reliability but also provides users with a smoother operating experience.

[0028] Temporary signal bundles can be used to switch circuits on and off, or they can be derived from high and low level signals through conversion.

[0029] The switch button 2 includes mechanical buttons such as buttons or micro switches, as well as touch buttons, photoelectric switches, or microwave radar switches.

[0030] The operation method includes at least one step: repeatedly outputting a specific number of 0 or 1 signals to the control circuit board 1 by pressing switch button 2 within a set time period. In designing the operation method, the device fully considers the balance between simplicity and flexibility, ensuring that the complexity of the operation steps can be flexibly adjusted according to actual needs. For example, within a preset time range, the user can generate different signal combinations by pressing the button at different intervals, thereby achieving diverse password input modes. This mechanism significantly enhances password strength.

[0031] Furthermore, the operation method may also include multiple sequential operation steps. Control circuit board 1 compares the temporary signal bundle output by the next operation step with the corresponding signal bundle preset by control circuit 1, provided that the temporary signal bundle output by the previous operation step matches the one preset by control circuit 1. Control circuit board 1 possesses intelligent recognition capabilities, accurately distinguishing the signal sequences corresponding to different operation steps and efficiently converting them into valid unlocking commands, further enhancing the system's adaptability and intelligence.

[0032] After a certain operation step is performed, indicator light 3 also indicates whether the operation step matches the corresponding signal bundle preset by control circuit 1. If the match is successful, the indicator light will turn green, prompting the user to continue to the next operation; if the match fails, the indicator light will turn red and flash briefly to remind the user to recheck the current operation step. This instant feedback mechanism not only effectively reduces user errors but also significantly improves the intuitiveness and convenience of the operation process.

[0033] Preferably, the number of 0 or 1 signals output by the switch button to the control circuit board within the time set in each operation step is different.

[0034] The technical solution of the electronic lock will be described in as much detail as possible through two specific embodiments below.

[0035] Example 1

[0036] The preset password signal bundle within the control circuit board 1 is a 10-second sequence of digital signals: "1, 1, 1, 1, 1". This preset signal bundle can be simply understood as a preset password. That is, the electronic lock unlocks only if the switch button 2 is pressed five times consecutively within 10 seconds. If the switch button 2 is pressed four or fewer times or six or more times consecutively within 10 seconds, the control circuit board 1 determines that the signal bundle does not match, and the electronic lock cannot unlock. By optimizing the algorithm, for example, setting the closing time of switch button 2 to be greater than 0.3 seconds and the open-circuit time between two closing presses to be greater than 0.3 seconds before considering pressing switch button 2 as a valid operation, otherwise it is considered an invalid operation. This avoids operational errors caused by signal fluctuations during button presses and also prevents forced unlocking through prolonged or high-frequency pressing.

[0037] The switch button 2 here is normally closed, meaning it is turned on when pressed and outputs a 1 signal.

[0038] Alternatively, a normally closed switch button 2 can be used, which opens when pressed and outputs a 0 signal. The output digital signal consists of 0s, such as "0, 0, 0, 0, 0".

[0039] Example 2

[0040] The preset signal bundle in the control circuit board 1 consists of three segments of digital signals "1, 1, 1, 1" - "1, 1, 1" - "1" within 10 seconds, with an interval of more than 5 seconds and less than 10 seconds between each segment.

[0041] The specific operating method is as follows:

[0042] (1) Press the switch button four times in a row within 10 seconds;

[0043] (2) Pause for 5 seconds or more before proceeding to the next step;

[0044] (3) Start within 10 seconds of the last button operation and press the switch button 2 three times in a row within 10 seconds;

[0045] (4) Pause for 5 seconds or more before proceeding to step three;

[0046] (5) Start within 10 seconds of the last button operation and press the switch button 2 once within 10 seconds;

[0047] (6) The electronic lock is unlocked.

[0048] If the number of times the switch button 2 is pressed consecutively within 10 seconds is not matched, or the time interval between two operations is not matched, the control circuit board 1 will determine that it is incompatible with the signal bundle, and the electronic lock cannot be unlocked. Combined with the indicator light 3, the user can intuitively and conveniently understand the operation process.

[0049] Example 3

[0050] This provides a method for clearing and changing the password of an electronic lock.

[0051] A system password different from the unlock password can be preset. By pressing and holding the switch button 2 for more than five seconds, you can enter the system mode. In this mode, entering the system password will clear the unlock password and enter the password modification mode. In this mode, you can set the number of times the switch button is pressed in a single or multiple times within 10 seconds and record it in the control circuit board 1 as a preset signal cluster.

[0052] The above descriptions are merely some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and all such modifications and improvements fall within the scope of protection of the invention.
