Description

Technical Field

[0001] This application belongs to the field of door lock technology, and in particular relates to a door lock and its control method, program product, and medium. Background Technology

[0002] With the advancement of smart lock technology, its application scope and user base are constantly expanding. Smart locks typically support multiple unlocking methods, such as facial recognition, fingerprint recognition, password recognition, and proximity card recognition. Due to its low barrier to entry, password unlocking is currently the most commonly used and frequently used method. In existing smart locks that support password recognition, the character positions on the keypad are generally fixed. For example, the characters on the keypad are illuminated by controlling the light-emitting elements inside the lock. Because the character positions on the keypad are fixed, if users repeatedly enter the same password, it may lead to password leakage and security risks. Furthermore, prolonged contact with the same keypad causes it to wear out quickly, thus affecting the lifespan of the lock.

[0003] In this situation, switching the position of characters on the password input keys, so that the same character appears in a different position each time the user enters the password, can solve the above problem to some extent. In existing technology, this function of switching the position of characters on the password input keys is generally achieved by installing a capacitive touchscreen in conjunction with an LCD screen in the smart lock. However, since capacitive touchscreens and LCD screens are expensive, this increases the production cost of the lock. Therefore, how to reduce the production cost of the lock while ensuring its security and reliability is a pressing technical problem that needs to be solved. Summary of the Invention

[0048] Currently, in existing smart locks that support password recognition, the character positions on the keypad are generally fixed. For example, the characters on the keypad are illuminated by a light-emitting element inside the lock. Because the character positions on the keypad are fixed, if users repeatedly enter the same password, it may lead to password leakage and security risks. Furthermore, frequent use of the same keypads causes them to wear out quickly, thus affecting the lock's lifespan. Therefore, by changing the character positions on the keypad, the same characters are displayed in different positions each time the user enters the password, thereby ensuring the security and reliability of the lock.

[0049] In existing technologies, the function of switching the position of characters on the password input keys is generally achieved by installing a capacitive touchscreen in conjunction with an LCD screen in a smart lock. However, since capacitive touchscreens and LCD screens are relatively expensive, this solution undoubtedly increases the production cost of the lock. Therefore, this application proposes a lock that can reduce the production cost of the lock.

[0050] To enable those skilled in the art to better understand this application, firstly, in conjunction with Figures 1 to 9 This application describes the door locks involved.

[0051] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 .

[0052] The door lock proposed in this application may include a door lock panel 4, the front of which has a groove, and the bottom of the groove has multiple first cutouts 41. The front is the side of the door lock panel 4 facing outwards. A touch panel 2 is embedded in the groove, and the touch panel 2 has second cutouts 21 that correspond one-to-one with the multiple first cutouts 41. Touch pads 22 are arranged around each second cutout 21. A main control board 5 is located on the back of the door lock panel 4 opposite to the touch panel 2. The main control board 5 has digital tubes 51 that correspond one-to-one with the multiple first cutouts 41. The digital tubes 51 are used to switch between displaying different characters. The main control board 5 is electrically connected to the touch panel 2 to receive the capacitive signal generated by the touch panel 2 when the user touches its touch pads 22.

[0053] Please refer to Figure 8 and Figure 9 .

[0054] The main control board 5 of the smart door lock is equipped with 10 digital tubes 51. Each digital tube 51 consists of seven parts: A, B, C, D, E, F, and G. It can display the 10 numbers from 0 to 9 through different combinations of light. When the user wakes up the door lock to enter a password, these 10 digital tubes 51 can display the numerical characters in a random order for the user to input.

[0055] Based on the door lock proposed in this application, the password characters displayed on the multiple digital tubes 51 arranged on the main control board 5 can change each time the user unlocks the door by entering a password. This achieves dynamic display of the password characters on the door lock, so that the position of the key (i.e., touch pad 22) touched by the user on the door lock keypad will be different each time the user enters the same password. By touching the touch pad 22, the capacitance of the touch pad 22 changes, thereby generating a capacitance signal, which is sent to the main control board 5. The main control board 5 determines the password entered by the user by the order in which the capacitance signals are sent from each touch pad 22, and determines whether to unlock the door for the user based on the entered password.

[0056] In this application, by combining the touchpad 2 and the digital tube 51 within the door lock, dynamic display of password characters can be supported. This effectively prevents criminals from deducing password information by observing the user's password input actions or key touch marks, thereby enhancing security and achieving an anti-peeping effect. It avoids the security risks associated with fixed password character positions, ensuring the security and reliability of the door lock. Simultaneously, the design of the touch pad 22 allows users to complete password input with simple touch, making the door lock operation more sensitive and convenient, thus improving the user experience. Furthermore, the technical solution proposed in this application, by combining the touchpad 2 and the digital tube 51 within the door lock, avoids the use of expensive capacitive screens and LCD displays while ensuring the security and reliability of the door lock. This significantly reduces the production cost of the door lock, making it more competitive in the market and providing consumers with a high-performance, cost-effective option.

[0057] Please refer to Figure 1 , Figure 2 , Figure 5 .

[0058] The door lock proposed in this application may also include a light guide 23, which is embedded in a groove and located between the touch panel 2 and the door lock panel 4. The light guide 23 has a third cutout 31 that corresponds one-to-one with the multiple first cutouts 41 in position. Each third cutout 31 is surrounded by annular ribs. The annular ribs pass through the first cutouts 41 and are close to the position on the main control board 5 around the digital tube 51.

[0059] In this application, the light guide 23 is made of an opaque material.

[0060] Based on the door lock proposed in this application, annular ribs are arranged around the third cutout 31 of the light guide 23. These ribs pass through the first cutout 41 and are closely attached to the position around the digital tube 51 on the main control board 5. When the digital tube 51 is lit, the light is ensured to shine only from the second cutout 21 corresponding to the front touchpad 2, preventing light from escaping to other areas of the second cutout 21. This ensures that the user is not interfered with by other light sources when entering the password, improving the concentration of character light display when using the door lock, thereby improving the accuracy of password input. In low-light environments, the user can clearly see the corresponding touch area, reducing the risk of accidental touches. The design of the annular ribs makes the light guidance more explicit, allowing the user to quickly find the correct input position and improving ease of use.

[0061] Please refer to Figure 1 , Figure 2 , Figure 3 .

[0062] The door lock proposed in this application may also include a keypad 1, which has a fourth cutout 11 that corresponds one-to-one with the multiple first cutouts 41 in position, and the fourth cutout 11 is covered with a semi-transparent oil film; the keypad 1 is attached to the front of the door lock panel 4.

[0063] Based on the door lock proposed in this application, by covering the fourth hollow 11 with a semi-transparent oil film, when there is no light inside the door lock, the semi-transparent oil film of the keypad 1 effectively blocks the view inside, and no content inside can be seen from the outside. When the digital tube 51 inside the door lock is lit, the emitted light passes through the keypad 1 and the semi-transparent oil film, allowing the user to clearly see the displayed content.

[0064] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 .

[0065] The door lock proposed in this application has a touch panel 2 with a first connector plug 23, a main control board 5 with a first connector socket 53, and a through hole 42 at the bottom of the groove; the first connector plug 23 passes through the through hole 42 and connects to the first connector socket 53 to realize the electrical connection between the main control board 5 and the touch panel 2.

[0066] Based on the door lock proposed in this application, the touchpad 2 is provided with a first connecting plug 23, which passes through the through hole 42 of the door lock panel 4 and connects to the first connecting socket 53 of the main control board 5, simplifying the circuit connection and ensuring a stable electrical connection between the touchpad 2 and the main control board 5. Touch pads 22 are arranged around each of the second cutouts 21 of the touchpad 2, enabling precise detection of the user's touch position. When the user touches the keyboard 1, the touch pads 22 sense the change in capacitance and transmit a signal to the main control board 5. This improves the sensitivity and accuracy of the touch response, ensuring the smoothness of the user's password input. The touchpad 2 is close to the back of the keyboard 1, allowing the user to directly interact with the touch pads 22 when touching the keyboard 1. This provides the user with more intuitive feedback when entering the password, reducing errors caused by input delays.

[0067] In other embodiments, the touch panel may be provided with a second connection socket, the main control board may be provided with a second connection plug, and a through hole may be provided at the bottom of the groove. The second connection plug passes through the through hole and connects to the second connection socket to realize the electrical connection between the main control board and the touch panel. This application does not impose too many limitations on this.

[0068] In this application, based on the inventive concept of the door lock described above, a door lock control method is also proposed, which is applied to the door lock as described in the above embodiments. Next, this application will elaborate on the proposed door lock control method.

[0069] Reference Figure 10 The diagram illustrates a flowchart of a door lock control method according to an embodiment of this application. This method can specifically be executed by a device with computational processing capabilities (such as the door lock itself), see reference [link to documentation]. Figure 10 As shown, the door lock control method includes at least steps 1001 to 1004, which are described in detail below:

[0070] Step 1001: In response to the user's unlocking request, obtain the current character display sequence, which is different from the character display sequence displayed when the user last unlocked the door.

[0071] Step 1002: According to the current character display sequence, control each digital tube on the main control board to display its respective character.

[0072] Step 1003: In response to the user's password input action on the touchpad, obtain the character sequence of the password to be verified.

[0073] Step 1004: If the password character sequence to be verified is consistent with the preset password character sequence, then control the door lock to open.

[0074] In this application, when a user issues an unlocking request, for example, when the user touches the door lock's touchpad, the door lock's main control board will generate a new current character display sequence. This current character display sequence is different from the character display sequence displayed when the user unlocked the door last time, so as to ensure the security and privacy protection of the user during the process of entering the door lock password each time the door is unlocked.

[0075] In one embodiment of this application, obtaining the current character display sequence can be performed according to the following steps 10011 to 10012:

[0076] Step 10011: Obtain the input frequency of each character in history, and the touch parameters of each touch pad on the touchpad in history, including the total touch duration and / or the total number of touches.

[0077] Step 10012: Based on the input frequency and the touch intensity parameters, determine the current character display sequence according to the strategy of evenly touching each touch pad on the touchpad.

[0078] In this embodiment, the door lock collects the input frequency of each character in history and the total touch duration and / or total number of touches of each touch pad on the touchpad. It then determines the current character display sequence according to a balanced touch strategy, thereby optimizing the display order of characters on the digital tube to improve security and user experience and prevent the password from being easily guessed.

[0079] Specifically, the balanced touch strategy may control the digital tube corresponding to the touch pad with a longer total touch duration and / or a larger total number of touches to display characters with a lower input frequency, and control the digital tube corresponding to the touch pad with a shorter total touch duration and / or a smaller total number of touches to display characters with a higher input frequency.

[0080] For example, a touchpad may contain 10 touch pads, arranged in the following order: touch pad A, touch pad B, touch pad C, touch pad D, touch pad E, touch pad F, touch pad G, touch pad H, touch pad I, and touch pad J. Taking the total number of touches for each individual touch pad as an example, the total number of touches for these 10 touch pads over the past 3 months is shown in Table 1 below:

[0081] Touch pads A B C D E F G H I J Total number of touches 50 50 60 65 70 75 80 85 90 100

[0082] Table 1

[0083] Furthermore, the input frequency of characters 1-10 over the past 3 months is shown in Table 2 below:

[0084] character 3 5 4 0 8 1 6 2 9 7 Input frequency (times / day) 5 times 4 times 4 times 3 times 3 times 2 times 1 time 1 time 1 time 1 time

[0085] Table 2

[0086] Based on the balanced touch strategy, the character display sequence (i.e., the current character display sequence) of the digital tube corresponding to each touch pad can be as shown in Table 3 below:

[0087] Touch pads A B C D E F G H I J The corresponding characters displayed on the digital tube 3 5 4 0 8 1 6 2 9 7

[0088] Table 3

[0089] In one embodiment of this application, obtaining the password character sequence to be verified can be performed according to the following steps 10031 to 10033:

[0090] Step 10031: Obtain the touch order of the touch pads on the touchpad that have been touched by the user.

[0091] Step 10032: Obtain the positional correspondence between each touch pad on the touchpad and the characters displayed on each digital tube on the main control board.

[0092] Step 10033: Based on the touch order and the position correspondence, determine the password character sequence to be verified.

[0093] To enable those skilled in the art to better understand this application, examples will be provided below in conjunction with Table 3.

[0094] As shown in Table 3, the positional correspondence between the touch pads on the touchpad and the characters displayed on the digital tubes on the main control board can be used. For example, if the touch order of the touch pads touched by the user on the touchpad is "BC AB FE", based on the touch order and the positional correspondence, the password character sequence to be verified can be determined to be "5 4 35 1 8". Furthermore, if the user's preset password character sequence is also "5 4 3 5 1 8", the door lock will be opened; otherwise, the door lock will be refused to open.

[0095] Based on the technical solution in this embodiment, by displaying less frequently used characters on the digital tubes corresponding to frequently touched touch pads, and more frequently used characters on the digital tubes corresponding to rarely touched touch pads, the advantages are as follows: First, by switching the digital tubes displayed for each character, the user's input action when entering the password on the touchpad will be different each time (i.e., the touch pads touched by the user and the order in which the touch pads are touched are different), making it difficult for criminals to guess the door lock password based on the user's input action, thereby reducing the risk of password guessing and improving the security of the door lock. Second, the strategy of evenly touching each touch pad on the touchpad ensures that the usage frequency of each touch pad is relatively consistent, avoiding premature wear of some pads due to frequent use while others are neglected, thereby extending the overall lifespan of the touchpad and reducing the maintenance cost of the door lock. At the same time, by combining the touchpad and digital tubes in the door lock, this application avoids the use of expensive capacitive screens and LCD screens while ensuring the security and reliability of the door lock, which can greatly reduce the production cost of the door lock.

[0096] Based on the same inventive concept, embodiments of this application provide a computer-readable storage medium storing at least one computer program instruction, which is loaded and executed by a processor to perform the operations described above.

[0097] Based on the same inventive concept, embodiments of this application provide a computer program product, the computer program product including computer instructions stored in a computer-readable storage medium and adapted to be read and executed by a processor to cause a computer device having the processor to perform the operations performed as described above.

Bus interface 1105 provides an interface between bus 1100 and receiver 1101 and transmitter 1103. Receiver 1101 and transmitter 1103 may be the same element, i.e., a transceiver, providing a unit for communicating with various other devices over a transmission medium. Processor 1102 is responsible for managing bus 1100 and general processing, while memory 1104 may be used to store data used by processor 1102 during operation.

[0100] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored as one or more instructions or codes on or transmitted via a computer-readable medium.
