Description

Technical Field

[0001] The utility model relates to the field of intelligent door locks, in particular to a door lock with a novel door handle. Background Art

[0002] As a key component of smart homes, smart door locks have experienced rapid growth in recent years. They integrate modern electronic technology with traditional door lock mechanisms to enhance home security and convenience. Compared to traditional mechanical door locks, smart door locks transform accessibility through electronic control systems, network connectivity, and multiple unlocking methods. Smart door locks primarily come in two types: handle-type and push-pull-type. Handle-type smart locks are unlocked similarly to traditional mechanical locks, requiring a push of the handle. Typically, after successful authentication, the user still needs to turn the handle to unlock the door. The advantage of handle-type smart locks is their increased security, making them less easily accessible to bad actors.

[0003] However, existing handle-based smart door locks have also exposed some issues in actual use. To facilitate leaving the house, users can simply unlock the door using the door handle. However, young children may learn to open the door lock by watching, posing a safety hazard to the family. Therefore, users who encounter such issues need to purchase and install a door handle safety lock to prevent children from turning the handle and opening the door lock, which increases user costs and complexity.

[0004] Furthermore, when users carry things and need to repeatedly enter and exit the house, they need to unlock the door each time, which can be very cumbersome. Frequent unlocking can easily deplete the door lock's battery, potentially preventing it from unlocking when needed, affecting the user's daily life and sense of security. These issues not only affect the user experience of handle-type smart door locks but also, to a certain extent, limit their market promotion and adoption.

[0005] To sum up, although handle-type smart door locks perform well in improving home security, they still need further optimization and improvement in terms of user convenience and child safety. Utility Model Content

[0006] The purpose of the utility model is to provide a door lock with a novel door handle.

[0007] In order to achieve the above-mentioned object, the present invention adopts the following scheme: a door lock with a novel door handle, comprising: an inner lock housing assembly mounted on the inner side of a door leaf and an outer lock housing assembly mounted on the outer side of the door leaf, wherein a door lock controller is provided inside the inner lock housing assembly and the outer lock housing assembly;

[0008] A handle rotatably mounted on each front panel of the inner lock housing assembly and the outer lock housing assembly, the handle being connected to the lock cylinder of the door lock via a transmission rod, and the door lock controller driving the transmission rod via a motor to control the lock cylinder to unlock or lock the door lock;

[0013] A locking member is provided on the handle of the built-in lock housing assembly and is used to lock the rotation of the handle.

[0014] By integrating a fingerprint recognition panel and password area on the handle, users can unlock the door both from outside and inside, and can also set different permissions for different groups of people. For example, specific family members or staff can be given access only from the outside or control from the inside, allowing for more flexible security management. The locking element is designed to limit the rotation of the handle, adding a function to prevent children from accidentally opening the door lock. It can also be physically set to the normally open state, greatly improving the flexibility, convenience, and safety of the smart door lock.

[0015] As a preferred solution of the present invention, the locking member includes:

[0016] A sliding sleeve is slidably mounted on the rotating shaft of the handle, and locking teeth are provided along the circumference of the rear end of the sliding sleeve;

[0017] The mating surface A is provided on the inner wall of the circumference of the sleeve and the mating surface B is provided on the outer wall of the rotating shaft of the handle. The mating surface A and the mating surface B can be clearance-fitted with each other, so that the sleeve rotates synchronously with the rotating shaft of the handle.

[0018] A fixing ring, which is fixed to the front panel of the built-in lock housing assembly by screws, the inner ring of which surrounds the rotating shaft of the handle and is provided with a locking groove;

[0019] The design of the locking sleeve and locking teeth of the locking part allows the user to manually lock or unlock the rotation of the handle, ensuring that the handle cannot be rotated at will when not in use. This effectively solves the safety problem of accidental operation by young children at home.

[0020] The push-and-press self-locking mechanism is located between mating surfaces A and B. When the sliding sleeve is pressed backward, causing the locking teeth to enter the locking groove, the push-and-press self-locking mechanism locks the sliding sleeve in place. When the sliding sleeve is pressed again, the push-and-press self-locking mechanism releases the lock on the sliding sleeve, returning it to its initial position. The introduction of the push-and-press self-locking mechanism further enhances the user experience. This mechanism locks and unlocks the handle by pressing the sliding sleeve, simplifying the process and allowing the user to quickly switch between handle states. This design not only improves safety but also facilitates daily operation, especially for short outings or repeated entry and exit.

[0021] As an optimal solution of the present invention, the push-and-press self-locking mechanism includes an annular guide groove and a pull rod. The annular guide groove is arranged on the mating surface A. One end of the pull rod is fixed on the mating surface B, and the pull rod can swing around the fixed point. The other end of the pull rod is inserted into the annular guide groove after multiple bending, and moves unidirectionally along the internal path of the annular guide groove. The paths at the front and rear ends of the annular guide groove are conical, and the paths on the left and right sides are parallel structures parallel to each other.

[0022] As a further feature of the present invention, each bend along the bottom surface of the annular guide slot is provided with a sloping step with the same orientation, ensuring that the end of the pull rod can only move in one direction along the annular guide slot. The sloping step design further ensures the stability and reliability of the pull rod's movement, thereby improving the precision of the locking and unlocking operations of the sleeve.

[0023] As a further solution of the present invention, a reset member is provided between the sliding sleeve and the rotating shaft of the handle, which can reset the sliding sleeve after movement.

[0024] As a preferred solution of the present invention, the reset member is a tension spring with one end fixed to the front end of the sliding sleeve and the other end fixed to the handle shaft.

[0025] As a preferred embodiment of the present invention, the sliding sleeve is assembled from two curved shells that are fastened together by a snap-fit ​​mechanism. Mating surfaces A are located on the inner walls of each curved shell, and mating surfaces B are symmetrically located on the outer walls of the handle's rotating shaft. The locking teeth extend integrally from the rear ends of each curved shell. The sliding sleeve's design, assembled from two curved shells connected by snap-fit ​​mechanisms, facilitates installation and maintenance.

[0026] As a further solution of the present invention, protruding pressing ears are respectively provided on the outer walls of the two arc-shaped shells. By adding the pressing ears, the user can more easily perform manual operation of the sliding sleeve, thereby improving the user experience.

[0027] As a preferred embodiment of the present invention, the power module includes a battery compartment located within the internal lock housing assembly for accommodating the battery, and a charging port located on the external lock housing assembly for charging the internal battery. The external lock housing assembly has a charging port that allows users to charge the battery using a power bank, eliminating the need for frequent battery replacements and ensuring the longevity of the door lock, preventing the lock from being unlocked due to power depletion.

[0028] As a preferred solution of the present invention, a mechanical key slot is provided at the bottom of the outer lock housing assembly, which provides users with an emergency unlocking method when the electronic system fails, thereby improving overall safety and reliability.

[0029] In summary, the beneficial effects of the present invention compared to the prior art are as follows: By providing fingerprint recognition panels and password areas on both the inner and outer panels, the present invention improves the security and ease of use of smart door locks. The simultaneous configuration of fingerprint recognition and password input functions inside and outside the door allows users to quickly unlock or lock the door, whether indoors or outdoors, which is particularly efficient in emergency situations. Furthermore, the locking member effectively locks the handle through the cooperation of the sliding sleeve and the locking teeth, preventing unauthorized rotation. This not only enhances anti-theft and anti-theft performance, but also avoids the problem of the handle being arbitrarily rotated when not in use. This design effectively addresses the safety risks of children's misoperation, and users do not need to install an additional safety lock.

[0030] Furthermore, the introduction of a push-to-lock mechanism allows users to lock and unlock the handle with a single click, eliminating the need for frequent manual rotation and unlocking operations, simplifying daily use. This is especially true when transporting items, as the door lock can be easily operated with one hand, eliminating the need to frequently put items down or switch hands. This significantly improves convenience while ensuring the door lock's safety and user experience. BRIEF DESCRIPTION OF THE DRAWINGS

The door lock controller drives the transmission rod 30 by driving a motor and engaging a clutch, thereby controlling the unlocking or locking of the door lock cylinder 11. The method of unlocking or locking the door lock cylinder 11 is conventional technology and will not be described in detail here. This method can be implemented by referring to the connection and drive methods of conventional, existing handle-type smart door locks. Each handle 3 is equipped with a fingerprint recognition panel 4 for controlling door lock opening via fingerprint recognition. A password area 6 for controlling door lock opening via a digital password is provided on the front panel of each of the inner lock housing assembly 1 and the outer lock housing assembly 2. A power module 7 is provided within each of the inner lock housing assembly 1 and the outer lock housing assembly 2. The fingerprint recognition panel 4, the door lock controller, the password area 6, and the motor are all powered by the power module 7. It should be noted that the door lock controller in this embodiment is a conventional control circuit board that integrates various components, including a microprocessor, a motor driver module, a wireless communication module, a fingerprint recognition sensor interface, a password input module interface, a power management module, an unlocking status feedback module, an alarm module, and a storage module. The microprocessor (MCU / CPU) is responsible for processing all input signals (such as fingerprints, passwords, and remote control) and controlling door lock operations, such as locking and unlocking. The motor driver module is responsible for controlling the operation of the motor, driving the lock cylinder 11 to lock or unlock. Wireless communication module: This includes modules such as Wi-Fi, Bluetooth, or Zigbee, and is used for wireless connection to mobile phones or smart home systems, enabling remote control and status feedback. Fingerprint sensor interface: This connects to the fingerprint recognition panel, processes fingerprint scan information, and transmits the data to the controller for verification. Password input module interface: This connects to the password input area, processes the password input information, and matches it with the preset password. Power management module: This manages the battery power and charging status, ensuring the smart door lock operates normally during power outages and preventing the lock from failing due to battery depletion. The power module 7 includes a battery compartment 71 located within the internal lock housing assembly 1 for receiving batteries, and a charging port 72 located on the external lock housing assembly 2 for charging the internal battery.

Storage module: This stores information such as fingerprints and passwords, as well as logs such as unlocking time and operation history.The fingerprint recognition panel 4 and the password area 6 are connected to the door lock controller via a wireless communication module integrated into the door lock controller to achieve remote data transmission and control the unlocking and locking operations of the lock cylinder 11. In order to prevent emergency unlocking in the event of an electronic system failure, a mechanical key slot 21 is provided at the bottom of the outer lock housing assembly 2.

[0046] It is important to note that in order to prevent unauthorized rotation operations, enhance the anti-theft and anti-pry performance of the door lock, and prevent the handle from being rotated at will when not in use, a locking member 5 is provided on the handle 3 of the internal lock shell assembly 1, which is used to lock the rotation of the handle 3, thereby effectively solving the safety hazard of misoperation by young children and allowing users to install no additional safety locks. Specifically: the locking member 5 includes a sleeve 51 that can be slidably mounted on the rotating shaft of the handle 3 and a locking tooth 52 arranged along the circumference of the tail end of the sleeve 51. The sleeve 51 is assembled by two arc-shaped shells that are buckled together, and the locking teeth 52 extend integrally along the tail ends of the two arc-shaped shells. The outer walls of the two arc-shaped shells are respectively provided with a radially extending pressing ear 53 for facilitating pressing operations. Mating surfaces A54 are provided on the inner walls of the two arcuate housings, respectively. Mating surfaces B31 are symmetrically provided on the outer wall of the shaft of the handle 3, where the sliding sleeve 51 resides. Mating surfaces B31 and A54 are parallel to the axis of the shaft of the handle 3, and there is a clearance fit between the mating surfaces A54 and B31, allowing the sliding sleeve 51 to rotate synchronously with the shaft of the handle 3 while also allowing the sliding sleeve 51 to slide along the axis of the shaft of the handle 3. A fixing ring 8 is screwed to the front panel of the internal lock housing assembly 1. The inner ring of the fixing ring 8 surrounds the shaft of the handle 3 and is provided with a locking groove 81. Pushing the sliding sleeve 51 axially backward along the shaft of the handle 3 causes the locking teeth 52 to engage with the locking groove 81. At this point, the sliding sleeve 51 cannot rotate relative to the fixing ring 8. Due to the mutual fit between the mating surfaces A54 and B31, the handle 3 is locked, preventing it from rotating.

[0047] In addition, in order to make the operation faster, the user can quickly switch the state of the handle to achieve the operation of locking or unlocking the handle. Figure 1 and Figures 4 to 11As shown, a push-and-press self-locking mechanism 9 is provided between the mating surface A 54 and the mating surface B31. When the sleeve 51 is pressed to slide backward, causing the locking tooth 52 to insert into the locking groove 81, the push-and-press self-locking mechanism 9 locks the position of the sleeve 51. When the sleeve 51 is pressed again, the push-and-press self-locking mechanism 9 releases the lock on the sleeve 51, returning the sleeve 51 to its initial position. Specifically, the push-and-press self-locking mechanism 9 includes an annular guide groove 91 and a pull rod 92. The annular guide groove 91 is provided on the mating surface A 54. One end of the pull rod 92 is fixed to the mating surface B31 and can swing about a fixed point. The other end of the pull rod 92 is inserted into the annular guide groove 91 after being bent multiple times and moves unidirectionally along the internal path of the annular guide groove 91. The paths at the front and rear ends of the annular guide groove 91 are both tapered, and the paths on the left and right sides are parallel to each other and arranged in parallel. A reset member 10 is provided between the sleeve 51 and the shaft of the handle 3 to reset the sleeve 51 after movement. The reset member 10 is a tension spring with one end fixed to the front end of the sleeve 51 and the other end fixed to the shaft of the handle 3. Figure 5 As shown, the sleeve 51 is at the front end of the handle 3 rotation axis. At this time, the end of the pull rod 92 away from the fixed point is inserted into the tip of the tapered inner path at the front end of the annular guide groove 91. When the sleeve 51 is pressed to slide backward along the handle 3 rotation axis, as shown in FIG. Figure 6As shown in , the end of the pull rod 92 away from the fixed point will slide into the parallel internal path on one side and slide along the tapered internal path at the tail end of the annular guide groove 91 to the recessed position of the tapered internal path at the tail end. Under the action of the tension spring, it is locked in this position. At this time, the position of the sleeve 51 is locked, and the handle 3 cannot be rotated. When the sleeve 51 is pressed again to move it backward, the end of the pull rod 92 away from the fixed point will slide along the tapered internal path at the tail end of the annular guide groove 91 to the corner at the tail end. The sleeve 51 is released, and under the action of the tension spring, the sleeve 51 moves forward. The end of the pull rod 92 away from the fixed point will slide from the corner at the tail end of the annular guide groove 91 into the parallel internal path on the other side until it returns to the tip of the tapered internal path at the front end of the annular guide groove 91. In order to ensure that the end of the pull rod 92 can only move in one direction along the annular guide groove 91 and will not move in the opposite direction, each turn along the bottom surface of the annular guide groove 91 is provided with an inclined step 93 with the same direction, so that the pull rod 92 can only move along a specific trajectory and cannot move in the opposite direction. During use, when the handle 3 on the inner lock housing assembly 1 is in a horizontal position, the sliding sleeve 51 is pressed back to lock the handle 3 in a horizontal state. Even if the fingerprint recognition panel 4 and the password area 6 are cracked on the outside, the door lock cannot be opened by the handle 3 on the outer lock housing assembly 2. When it is necessary to repeatedly enter and exit the door, the handle 3 on the inner lock housing assembly 1 is rotated to the unlocking position, and then the sliding sleeve 51 is pressed to allow the locking tooth 52 to be inserted into the locking groove 81, so that the door lock can be kept open for a long time, which is convenient for users to enter and exit at any time, and can also close the door to prevent children or pets at home from slipping out.

[0048] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
