Description

Technical Field

[0001] This utility model relates to the field of intelligent security equipment technology, and in particular to a multimodal intelligent door lock with a single-touch limit structure. Background Technology

[0002] Smart door locks are a new type of door control device that integrates electronic information technology, biometric technology, mechanical structure design and wireless communication technology. Its core function is to unlock and lock the door through non-mechanical key authentication methods (such as fingerprint, face, password, etc.). It also has intelligent functions such as status monitoring, remote control and security protection. It is widely used in residential, apartment, office and other scenarios and is one of the core entry points of smart home systems.

[0003] With the development of smart homes, smart door locks are gradually replacing traditional mechanical locks due to their convenience and security. However, existing smart door locks still have the following problems in practical applications: traditional door lock handles have no travel limit during rotation, and violent rotation or misoperation can easily cause deformation of internal transmission components. When the door lock is closed, the rigid collision between the bolt and the latch can easily cause wear on the bolt, shorten its service life, and easily cause structural damage. Therefore, a multimodal smart door lock with a single-touch limit structure is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a multimodal smart door lock with a single-touch limit structure, which can solve the technical problems of existing traditional door lock handles having no travel limit during rotation, violent rotation or misoperation easily causing deformation of internal transmission components, and the rigid collision between the lock tongue and the latch easily causing wear of the lock tongue when the door lock is closed.

[0006] To solve the above-mentioned technical problems, this utility model provides a multimodal smart door lock with a single-touch limit structure, adopting the following technical solution: It includes a door lock frame, inside which two fixed rods are symmetrically installed, and smart panels are fixedly installed on the front and rear sides of the fixed rods. Handles are rotatably installed on the outer walls of both smart panels. One end of each handle is located inside the smart panel and is equipped with a connecting rod. One end of each connecting rod is fixedly equipped with a limit block. A positioning plate is fixedly installed inside the two smart panels relative to the limit block. A buffer spring is fixedly installed on the outer wall of the positioning plate. Multiple latches are fixedly installed on one side of the door lock frame, and a damper is fixedly installed at one end of each latch inside the door lock frame. A keypad is fixedly installed on the outer wall of the smart panel located outside the door.

[0007] Optionally, limit slots are provided inside the two smart panels, and the limit blocks are rotatably installed inside the limit slots, with the limit blocks and buffer springs positioned relative to each other.

[0008] Optionally, a buffer pad is fixedly provided at one end of each of the plurality of dampers. The buffer pad is made of polyurethane material. The damper is hydraulic and is installed at the connection between the lock tongue and the lock body shell.

[0009] Optionally, a face recognition device is fixedly installed on the upper front side of the smart panel, and a voiceprint wake-up device is fixedly installed on the outer wall of the smart panel below the password keypad. An indicator light is fixedly installed on the upper outer wall of the smart panel.

[0010] Optionally, a fingerprint recognition plate is fixedly installed at one end of the handle, and the door lock frame is made of stainless steel.

[0011] Optionally, a pressure sensor is fixedly installed inside the handle, a trigger button is fixedly installed on the upper end of the pressure sensor, and an infrared sensor is fixedly installed on the front side of the outer wall of the handle.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By rotating the handle, the user drives the internal linkage of the door lock to move, thereby causing the handle limit block to rotate and contact and squeeze the buffer spring on the outside of the positioning plate, avoiding component deformation caused by excessive rotation of the handle. The hydraulic damper of the latch buffer assembly works in conjunction with the polyurethane buffer pad to reduce the rigid collision between the latch and the latch, which is beneficial to improving the service life of the latch, facilitating its effective limitation, and protecting the structure.

[0013] With its single-touch trigger and automatic recommended unlocking mode design, there is no need to wake up the screen or manually select. The entire process from triggering to unlocking takes less than two seconds, making it especially suitable for scenarios where both hands are holding objects. The multi-modal unlocking module covers fingerprint, face, and voiceprint recognition, making it suitable for different groups such as the elderly and children. It solves the problem of poor adaptability of single-modal unlocking, providing users with multiple convenient ways to open the door lock and improving the applicability of smart door locks.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1 —4. This utility model will be described in further detail.

[0019] Reference Figure 1-4In this embodiment, in order to solve the technical problems of existing traditional door lock handles having no travel limit during rotation, violent rotation or misoperation easily causing deformation of internal transmission components, and the rigid collision between the lock tongue and the latch easily causing wear of the lock tongue when the door lock is closed, this utility model discloses a multimodal smart door lock with a single-touch limit structure. The system includes a door lock frame 1, with two fixed rods 12 symmetrically installed inside the door lock frame 1. Smart panels 2 are fixedly installed on the front and rear sides of the fixed rods 12. Handles 3 are rotatably installed on the outer walls of the two smart panels 2. One end of each handle 3 is located inside the smart panel 2 and is equipped with a connecting rod. A limit block 31 is fixedly installed at one end of each connecting rod. A positioning plate 33 is fixedly installed inside the two smart panels 2 relative to the limit block 31. A buffer spring 34 is fixedly installed on the outer wall of the positioning plate 33. Multiple latches 10 are fixedly installed on one side of the door lock frame 1, and a damper 102 is fixedly installed at one end of each latch 10 inside the door lock frame 1. A keypad 9 is fixedly installed on the outer wall of the smart panel 2 on the outside of the door. Specifically, the two smart panels 2 have limit grooves 32 inside, and the limit block 31 is rotatably installed inside the limit groove 32, and the limit block 31 is positioned relative to the buffer spring 34.

[0020] When the handle 3 is rotated, the limiting block 31 on the internal connecting rod is rotated, which causes the limiting block 31 to come into contact with and squeeze the buffer spring 34 on the outside of the positioning plate 33 during the rotation process, thereby buffering and dispersing the rotation pressure and avoiding damage caused by excessive rotation pressure. Specifically, each of the multiple dampers 102 has a buffer pad 101 fixedly installed at one end. The buffer pad 101 is made of polyurethane material. The damper 102 is hydraulic and is installed at the connection between the lock tongue 10 and the lock body shell.

[0021] By using a polyurethane buffer pad 101 and attaching it to the end of the latch 10, and by using a hydraulic damper 102 and installing it at the connection between the latch 10 and the lock body shell, the extension and retraction speed of the latch 10 is reduced, thus avoiding rigid collisions. Specifically, a face recognition device 7 is fixedly installed on the upper front side of the smart panel 2, and a voiceprint wake-up device 6 is fixedly installed on the outer wall of the smart panel 2 below the password keypad 9. An indicator light 8 is fixedly installed on the upper outer wall of the smart panel 2.

[0022] By setting up a face recognition device 7, a password keypad 9, and a voiceprint wake-up device 6, users can easily use different unlocking methods according to different situations. Multiple intelligent unlocking methods improve the convenience and versatility of opening the door lock. Specifically, a fingerprint recognition plate 11 is fixedly installed at one end of the handle 3, and the door lock frame 1 is made of stainless steel.

[0023] The fingerprint recognition plate 11 is set to improve the convenience of the opening method. At the same time, the door lock frame 1 is made of stainless steel to improve the rigidity of the door lock frame 1 and extend its service life.

[0024] Specifically, a pressure sensor 41 is fixedly installed inside the handle 3, a trigger button 4 is fixedly installed on the upper end of the pressure sensor 41, and an infrared sensor 5 is fixedly installed on the front side of the outer wall of the handle 3.

[0025] By using silicone material for the trigger button 4, it is embedded in the top of the handle with a pressing stroke of 0.5mm and a trigger force of 3-5N. At the same time, the pressure sensor 41, model FSS1500N, is attached to the bottom of the trigger button 4. After detecting the pressing signal, it wakes up the multi-modal unlocking module. The internal wake-up module uses a low-power MCN model STM32L431, which only starts the unlocking process when the trigger button 4 is pressed, thus reducing energy consumption.

[0026] The specific working principle is as follows: When in use, when the user holds an object with both hands or holds the handle with one hand, their finger naturally presses the trigger button 4 on the top of the handle 3. The pressure sensor 41 at the bottom of the trigger button 4 detects the pressing signal and sends a wake-up command to the low-power mode. The infrared sensor 5 and the touch sensor simultaneously detect whether there is a hand holding the handle. After confirming that it is not a mis-touch, the authentication stage begins. At the same time, the user can unlock the door through the following methods: if the user's face is facing the door lock at a distance of 0.3-1.5m, the face recognition device 7 is activated first; if the user is holding the handle, the fingerprint recognition plate 11 on the inside of the handle is activated first; if the user is at a distance of 1-3m, the voiceprint wake-up device 6 can be used to activate the voiceprint recognition. In the identity verification process, the real-time progress feedback of each module can be confirmed by the flashing of indicator light 8. When the door lock needs to be opened, after the transmission mechanism receives the unlocking signal, it drives the bolt 10 to retract. The damper 102 slows down the extension and retraction speed of the bolt 10 to avoid rigid collision with the latch. The user rotates the handle 3 to drive the internal linkage of the door lock to move. When the handle is rotated to 90 degrees, the limit block 31 blocks the rotation and the buffer spring 34 on the outside of the positioning plate 33 compresses and absorbs the impact force to prevent the handle from being over-rotated and causing damage to the components. After the handle 3 is rotated to the correct position, the door can be opened smoothly. The buffer pad 101 and damper 102 of the bolt 10 buffer assembly ensure that the bolt 10 is smoothly reset when closed, reducing wear.
