A rectangular finger inlet 32 is formed in the lower part of the outer panel in a longitudinal direction, a fingerprint password input unit 4 is installed at the position, corresponding to the finger inlet, of the rear end of the outer panel, and the fingerprint password input unit comprises a main body part 41 and a cover body 42 connected to the rear end of the main body part; a fingerprint input module mounting part 412 is arranged on the left side of the front part of the main body part close to the outer panel, and a finger extending cavity 411 with an opening communicated with a finger extending port is formed between the right side and the rear side of the fingerprint input module mounting part of the main body part and the cover body; a fingerprint password input module 43 is installed at a position opposite to the cover body in the fingerprint password input part.
The fingerprint password input module comprises a password input module circuit board 433, 4 longitudinally arranged pressure sensors 432 connected to the password input module circuit board, and 4 fingerprint acquisition modules 431 respectively and fixedly connected to the pressure sensors.
A confirmation key 34 is installed at the left side of the upper portion of the finger extending opening on the outer panel, a display screen 33 is installed at the upper portion of the outer panel, and a numeric keyboard 31 is installed at the position between the finger extending opening and the display screen on the outer panel.
The display screen, the numeric keyboard, the pressure sensors, the fingerprint acquisition module and the confirmation keys are respectively and electrically connected with a control circuit board arranged in the inner panel.
When the lock is unlocked, a group of digital passwords with 6-10 digits are input through a digital keyboard, and if the digital passwords are input incorrectly, the control circuit board prompts to input the characters of the passwords again through the display screen or prompts to input the digital passwords again through the voice of a loudspeaker; if the digital password is correctly input, the control circuit board displays a prompt through the display screen to continuously input a group of fingerprint passwords or continuously inputs a group of fingerprint passwords through a loudspeaker voice prompt; the digital password is set by the user in advance.
After inputting correct digital password, the finger of the right hand extending into the fingerprint password input device extends into the cavity, and a group of fingerprint passwords is input on the fingerprint password input module.
When a fingerprint password is input through the fingerprint password input module, an index finger, a middle finger, a ring finger and a little finger are respectively and correspondingly pressed on four fingerprint acquisition modules which are longitudinally arranged along the fingerprint password input device, each finger presses each fingerprint acquisition module according to the password sequence to enable the pressure on a pressure sensor at the corresponding position to reach a preset value, the pressure value on the pressure sensor is displayed on a display screen in real time, 4 lines of two-digit numbers are displayed on the display screen in real time, the 4 lines of numbers respectively correspond to the pressure values of the four pressure sensors which are arranged from top to bottom, and when the pressure value on the pressure sensor at the corresponding position is zero, the corresponding line on the display screen dynamically displays a pseudo-random number; when the pressure sensor at each position presses a preset numerical value, the confirmation key is pressed by a thumb, after the confirmation key is pressed, the control circuit board extracts fingerprint information acquired by the fingerprint acquisition module at the corresponding position, four fingerprint sequence lines which are arranged in sequence and have different pressure values are formed, the control circuit board compares the fingerprint sequence lines with fingerprint sequence line information set by a user independently, if the fingerprint sequence line information is consistent, the password input is judged to be correct, the control circuit board controls the motor or the electromagnet to drive the inclined lock tongue and the square lock tongue to execute the unlocking step, if the fingerprint sequence line information is inconsistent, the password input is judged to be wrong, and the user is prompted to input the password again through the display screen.
The real-time pressure value displayed on the display screen has the precision of 0.1 newton, and is converted into an integer by multiplying by 10 to be displayed, and if the pressure value is 0.2 newton, 2 is displayed on the display screen (hereinafter, the value displayed on the display screen is referred to as the pressing force).
The preset value of the pressure is a fixed value, and when the pressure sensor is pressed, and the difference value between the real-time pressure value and the set fixed value is less than 0.2 Newton, the real-time pressure value is considered to be equal to the preset value; the accuracy of the real-time pressure value displayed on the display screen is 0.1 newton.
In order to more directly understand the key of the fingerprint password input module, the following examples further illustrate: for example, the index finger, the middle finger, the ring finger and the little finger correspond to 1, 2, 3 and 4 respectively, if the password is set to 2143 and the pressing force is set to 8765 (the selectable pressure value is 1-8), the middle finger is pressed down in sequence, the confirmation key is pressed down when the second line on the display screen is displayed within the range of 6 to 10, the confirmation key is pressed down when the index finger is pressed down and the first line on the display screen is displayed within the range of 5 to 9, the little finger is pressed down, the confirmation key is pressed down when the fourth line on the display screen is displayed within the range of 4 to 8, and the confirmation key is pressed down when the ring finger is pressed down finally, and the third line on the display screen is displayed within the range of 3 to 7.
Of course, the password may be a commonly used 6-digit number, for example, when the password is 232421 and the pressing force is 876567, the middle finger (second row of pressure displays 6 to 10), the ring finger (third row of pressure displays 5 to 9), the middle finger (second row of pressure displays 4 to 8), the little finger (fourth row of pressure displays 3 to 7), the middle finger (second row of pressure displays 4 to 8), and the index finger (first row of pressure displays 5 to 9) are pressed in sequence.
And when the pressure value of the pressure sensor at the corresponding position is zero, the corresponding action on the display screen dynamically displays the pseudo-random number. The pseudo random number can be calculated according to the real-time pressing force of the pressure sensor subjected to the pressure, for example, when the pressure sensor at one position is subjected to a pressure value N (N is 1-8), the pressures at the other three positions are shown as (N + 2), (N + 3) and (N-1).
Through the technical means, because four lines of numbers on the display screen are relatively close, only the user knows which line of numbers to look at, and even if looking at the display screen to observe the user to operate, other people cannot know the specific password input by the user.
The width of the finger extending opening is 20-30 mm.
Example 2
The present embodiment is modified from embodiment 1 as follows: when a part of fingers of a user used for inputting a fingerprint password are injured and cannot normally input a complete fingerprint password, the user firstly inputs a group of passwords with 6 digits on a numeric keyboard, then the user presses any more than one finger of a forefinger, a middle finger, a ring finger and a little finger on a fingerprint acquisition module at any position, a control circuit board extracts fingerprint information acquired by at least one fingerprint acquisition module and compares the fingerprint information with fingerprint information set by the user independently, after the user identity is matched, the control circuit board sends two groups of different dynamic verification codes to two mobile terminals bound with the corresponding user independently, after the user inputs the two groups of dynamic verification codes on the numeric keyboard, the control circuit board controls a motor or an electromagnet to drive an inclined lock tongue and a square lock tongue to execute an unlocking step, and the input sequence of the two groups of dynamic verification codes is unlimited.
The two mobile terminals are preferably carried by one user, the other is owned by family or friends of the user, and the user obtains the group of dynamic verification codes sent to the mobile phones of the family or friends in a calling mode.
Example 3
This example is modified from example 1 or 2 as follows: the left side and the right side of the finger extending opening are connected with soft foaming materials, and a gap of 10-15mm is reserved between the foaming materials on the left side and the right side of the finger extending opening. The foaming material makes the user's finger stretch into from finger stretching-in mouth after, the part that the user's finger lies in finger input intracavity is totally invisible, and other people can't judge that the user is which finger is operating, has further improved the security performance.
