Description

Technical Field

[0001] The present invention relates to the technical field of password locks, and in particular to a password lock and a password input method thereof. Background Art

[0002] Currently, combination locks are a common lock type used in a wide range of applications, particularly in door locks, safes, self-service lock boxes, and vehicles. Combination locks require no equipment and are easy to unlock. Their ease of use is comparable to that of fingerprint locks, surpassing those that require a swipe card, while offering far greater stability. Smart combination locks in everyday life typically require a password to open, typically entered via an input panel. Currently, solutions for password entry often utilize input panels with 10 numeric keys, encompassing the ten digits 0-9. However, conventional 10-key combination locks present several challenges. For one thing, due to limitations in usage scenarios, the combination lock may not accommodate a large number of numeric keys, or, when all the keys are in place, the individual numeric keys are too small to be easily entered. Furthermore, conventional 10-key combination locks offer limited confidentiality, making it easy for someone to directly enter the password and unlock the lock. Summary of the Invention

[0003] The present invention aims to provide a combination lock and a method for inputting a password therefor. The combination lock of the present invention has a numeric keypad with incomplete numbers, which is suitable for application scenarios where the combination lock is miniaturized. Moreover, the combination lock can convert a complete numeric password into a password that can be recognized by the combination lock with an incomplete numeric keypad, thereby achieving good confidentiality and security.

[0004] The technical solution of the present invention is a combination lock, which is provided with numeric keys, and the numeric keys are composed of 2 to 9 numbers from 0 to 9.

[0005] In the above-mentioned combination lock, the digital keys are composed of 2 to 9 consecutive numbers from 0 to 9.

[0006] The unlocking method of the aforementioned password lock is to enter the password only through 2-9 numeric keys. When entering the password, the original password is first escaped, so that the original password becomes an escape password consisting of 2-9 numbers, and then the escape password is entered through the numeric keys to complete the unlocking.

[0007] The password input method of the aforementioned password lock is that the original password escape method is base conversion; the numeric keys are composed of 2-9 consecutive numbers starting from 0.

[0008] In the aforementioned password input method for the password lock, the base conversion is to convert the original password into a base corresponding to the number of numeric keys supported by the current password lock, and the obtained base number is the escape password.

[0009] In the aforementioned password input method for the combination lock, for an original password that begins with 0, a non-zero number is added to the original password during the base conversion.

[0010] The password input method of the aforementioned password lock is that the original password escape method is meaning conversion; the numeric keys are composed of 4-9 consecutive numbers.

[0011] The aforementioned password input method for a password lock comprises the following steps: for a number key consisting of n consecutive digits, where n=4 or 5, the first n-2 digits of the number key are not converted in meaning, the last n-2 digits of the number key and the remaining unappeared digits are sorted in ascending order, and then the last n-2 digits of the number key are sequentially used as the tens digit, and n digits are sequentially used as the units digit to form a two-digit number, and the formed two-digit number is then used to sequentially represent the last n-2 digits of the number key and the remaining unappeared digits.

[0012] The password input method of the aforementioned password lock, wherein the meaning conversion is for a number key consisting of n consecutive numbers, 5<n≤9; the first n-1 numbers in the number key are not converted in meaning, the last n-1 numbers in the number key and the remaining unappeared numbers are sorted in ascending order, and then the last n-1 numbers in the number key are used as the tens digit, and n numbers are used in sequence as the units digit to form a two-digit number, and the formed two-digit number is then used to sequentially represent the last n-1 numbers in the number key and the remaining unappeared numbers.

[0013] Compared with the prior art, the password numeric keypad of the password lock of the present invention adopts the form of an incomplete numeric keypad. On the one hand, it can reduce the volume of the password lock and increase the area of ​​a single numeric keypad, making it convenient to input the password; on the other hand, the present invention adopts the form of incomplete numbers to represent the password of conventional complete numbers. In this way, even if the password of conventional complete numbers is told to others or accidentally leaked, there is no need to worry about others entering the password to unlock the password lock in the absence of a corresponding escape method, which shows good confidentiality and security. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the examples, but they are not intended to limit the present invention.

[0015] Example 1: A combination lock is provided with numeric keys, wherein the numeric keys are composed of 2 to 9 numbers from 0 to 9; the numeric keys are such as 0 and 1; 1 and 3; 2, 4 and 6, etc.

[0016] Example 2: A combination lock is provided with numeric keys, wherein the numeric keys are composed of 2 to 9 consecutive numbers from 0 to 9, such as 0 and 1; 1 and 2; 0, 1 and 2, etc.

[0017] Example 3: A method for unlocking a password lock, in which the password is input only through 2-9 numeric keys. When inputting the password, the original password is first escaped, so that the original password becomes an escape password consisting of 2-9 numbers, and then the escape password is entered through the numeric keys to complete the unlocking.

[0018] In this embodiment, the password generated by the complete digital password scheme is 6 to 9 digits long. Through digital conversion, the password length will become longer, as shown in the following Table 1:

[0019]

[0020] Table 1

[0021] The base conversion in this embodiment is to convert the original decimal password into a base system corresponding to the number of keys supported by the current lock, such as binary or quaternary. For example, if the lock supports four password digits (0, 1, 2, 3), the password 987654 is converted to quaternary as 3301020012, and converted to septenary as 11252313.

[0022] For passwords that do not start with 0, they can be converted using the base conversion method. If it is a decimal password that starts with 0, you need to add a non-zero number before the password. In this embodiment, the number 1 is used. For example, the generated decimal password is 098765, and the password after adding 1 is 1098765, which is converted to a 4-base password of 100301000311.

[0023] The password converted by base 1 contains consecutive numbers starting from 0. If the key numbers of the lock do not start from 0 or are discontinuous in the middle, the actual numbers of the combination lock need to be arranged from small to large, and then correspond to the consecutive numbers starting from 0 in order. For example, the password numbers of the lock are 1, 2, 3, 4. The corresponding relationship is shown in Table 2:

[0024] Lock button number Password Number 1 0 2 1 3 2 4 3

[0025] Example 4: A method for unlocking a password lock, in which the password is input only through 4 or 5 consecutive numeric keys. When entering the password, the original password is first escaped, so that the original password becomes an escape password consisting of 4 consecutive numbers, and then the escape password is entered through the numeric keys to complete the unlocking.

[0026] The meaning conversion is for a number key consisting of n consecutive numbers, where n = 4 or 5; the first n-2 numbers in the number key are not converted in meaning, the last n-2 numbers in the number key and the remaining numbers that do not appear are sorted in ascending order, and then the last n-2 numbers in the number key are sequentially used as tens digits, and n numbers are sequentially used as units digits to form a two-digit number, and the formed two-digit number is then used to sequentially represent the last n-2 numbers in the number key and the remaining numbers that do not appear.

[0027] Specifically, for a password lock with 4 numeric buttons, such as the numbers a, b, c, d (1, 2, 3, 4, or 0, 1, 2, 3, etc.);

[0028] The numbers that do not need to be escaped are: a, b;

[0029] Other numbers after escape are: ca, cb, cc, cd, da, db, dc, dd.

[0030] Please refer to Table 3 below for details:

[0031] 0 1 2 3 4 5 6 7 8 9 1234 31 1 2 32 33 34 41 42 43 44 0123 0 1 20 21 22 23 30 31 32 33 6789 86 87 88 89 96 97 6 7 98 99

[0032] Table 3

[0033] For example, if the original password is 652318 and it corresponds to a lock with the numbers 1234, the number 6 will be converted to 41, the number 5 will be converted to 34, the number 2 will remain 2, the number 3 will be 32, the number 1 will remain 1, and the number 8 will be converted to 43. Therefore, the password will be converted to 4134232143. For a lock with the numbers 0123, the password will be converted to 30232021132.

[0034] Specifically, for a combination lock with 5 numeric keys, such as the numbers a, b, c, d, e (for example, 1, 2, 3, 4, 5, or 0, 1, 2, 3, 4, etc.);

[0035] Numbers that do not need to be escaped: a, b, c;

[0036] Other numbers after escape are: da, db, dc, dd, de, ea, eb.
