Description

Technical Field

[0001] The utility model relates to the technical field of smart door locks, in particular to an embedded door handle based on the smart door lock. Background Art

[0002] As we all know, smart doors are improved upon traditional door handles, offering enhanced intelligence and simplicity in terms of user safety, identification, and management. These doors, combining safety, convenience, and advanced technology, have become widely popular. The handle is the actuator in smart doors.

[0003] Existing smart doors generally integrate functions such as automatic door opening and closing, video calling, video surveillance, doorbell, anti-theft detection, alarm, fingerprint and password lock automatic hiding, etc. With an increasing number of functions, convenient and fast smart doors are becoming more and more common in people's lives. However, among these various functions, we cannot open and close the door without a handle, so smart doors generally have a handle. Traditional handles are generally external, that is, directly set on the door lock. This setting is relatively common and not new to users. At the same time, the external location of the handle can easily affect the aesthetics of the door lock, making the door lock remain in the old style, thus affecting the product quality and greatly affecting the user experience.

[0026] like Figures 1 to 7 As shown, the present embodiment provides an embedded door handle based on a smart door lock, comprising a main body 1 installed on a smart door lock 100, the main body 1 having a built-in motor 2 and a control board 3 electrically connected to the door lock mainboard, a housing cavity 4 being opened on the surface of the main body 1, a flip cover 5 being connected to the axis at the cavity opening of the housing cavity 4, the motor 2 being connected to the shaft of the flip cover 5 through a transmission mechanism 6, so that the flip cover 5 can cover the housing cavity 4 or detach from covering the housing cavity 4 under the drive of the motor 2, a TOF sensor 51 for detecting whether someone is approaching and at least one infrared fill light 52 for use with the TOF sensor 51 are installed on the flip cover 5, the outer end surface of the flip cover 5 is provided with avoidance holes 53 at the TOF sensor 51 and the infrared fill light 52, a fingerprint recognition module 7 is provided on the inner wall of the housing cavity 4, and the TOF sensor 51, the infrared fill light 52, the fingerprint recognition module 7 and the motor 2 are all electrically connected to the control board 3.

[0027] The main innovation of this embodiment is that the fingerprint recognition module 7 is installed on the inner wall of the accommodating cavity 4, so that the fingerprint recognition module 7 cannot be seen from the outside of the lock body, and a flip cover 5 is provided to cover the accommodating cavity 4, so that the outside presents a simple integrated plane, thereby improving the product grade; at the same time, the TOF sensor 51 recognizes the approach of a person and automatically removes the flip cover 5 from covering the accommodating cavity 4. The edge of the accommodating cavity 4 can be used as a handle for consumers to grasp, and the fingerprint recognition module 7 is also located in the same place, so that the overall handle can be hidden.

[0028] Among them, by default, the flip cover 5 covers the opening of the accommodating cavity 4. When someone approaches (the detection distance can be set to 10cm-20cm), the TOF sensor 51 combined with the infrared fill light 52 can recognize that someone is approaching, and thus give a command to open the flip cover. The power supply will be provided by the internal mainboard of the smart door lock 100. After the control board 3 is connected to the instruction of the internal mainboard of the smart door lock 100, the motor 2 will start. After the motor 2 starts working, the shaft of the flip cover 5 is driven by the transmission mechanism 6 to rotate, and then the flip cover 5 also rotates synchronously. The rotation direction is the rotation inside the accommodating cavity 4. When the rotation is completed, After that, the flip cover 5 is separated from the cavity opening of the accommodating cavity 4, and the user's hand can be inserted from the cavity opening of the accommodating cavity 4 with the palm facing down, where the finger used to unlock is against the fingerprint recognition module 7. After the recognition is passed, the lock body is unlocked, and the user can grasp the edge of the accommodating cavity 4 here to open the door. At this time, the TOF sensor 51 is just above the palm, and can detect whether the user's palm is pulled out of the accommodating cavity 4. If the user's palm has not been removed from the accommodating cavity 4, the motor 2 will not reset. If it is detected that the palm has been separated from the accommodating cavity 4, the motor 2 will reset, and the flip cover 5 will cover the cavity opening of the accommodating cavity 4 again.

[0029] Furthermore, to better determine whether the flip cover 5 has rotated, a sensing PCBA 54 is installed within the flip cover 5 in this embodiment. The TOF sensor 51 and infrared fill light 52 are integrated on the sensing PCBA 54. The sensing PCBA 54 also integrates a Hall effect sensor (not shown). A magnet 8 is installed on the main body 1 at the position corresponding to the Hall effect sensor 54. The cooperation between the Hall effect sensor and the magnet 8 allows verification of whether the flip cover 5 has rotated after the unlock command is given.

[0030] Furthermore, with respect to the specific structure of the transmission mechanism 6, the transmission mechanism 6 of this embodiment may specifically include a reduction gear box 61 mounted on the motor 2 and a driven gear 62 fixedly mounted on the shaft of the flip cover 5, and a driving gear 63 is provided on the output shaft of the reduction gear box 61, and the driving gear 63 and the driven gear 62 are engaged with each other.

[0031] Furthermore, because the fingerprint recognition module 7 is hidden in the accommodating cavity and cannot be seen by the user, in order to facilitate blind operation by the user, the cavity wall of the accommodating cavity 4 of this embodiment is provided with an arc-shaped groove 9 at the fingerprint recognition module 7, and the recognition end face of the fingerprint recognition module 7 is placed at the center of the arc-shaped groove 9. In this way, relying on the guidance of the arc-shaped groove 9, the position of the fingerprint recognition module 7 can be quickly found and fingerprint authentication can be performed.

[0032] Furthermore, to prevent the user from forcibly pushing the flip cover 5 when not driven by the motor, a limit block 55 is provided at the top of the back of the flip cover 5 in this embodiment. A U-shaped limit opening 10 is provided on the inner end surface of the accommodating cavity 4 corresponding to the limit block 55. As the flip cover 5 is removed from the opening of the accommodating cavity 4, the limit block 55 gradually enters the limit opening 10 until the limit block 55 abuts against the bottom of the limit opening 10. In this way, when the flip cover 4 is in the open state, the limit block 55 and the limit opening 10 prevent the user from further pushing the flip cover 5, thus providing a protective limit.

[0033] Furthermore, to provide waterproof protection, the outer surface of the flip cover 5 of this embodiment is covered with a cover plate 56. The cover plate 56 is provided with a light-transmitting area 57 at least at the avoidance hole 53 to allow light to pass through. A waterproof rubber sleeve 58 is provided between the protruding end of the TOF sensor 51 and the avoidance hole 53.

[0034] Furthermore, in order to supplement the power supply in special circumstances, such as when the power inside the door lock is suddenly insufficient and the smart unlocking cannot be performed, a charging port 11 electrically connected to the control board 3 is provided at the edge of the accommodating cavity 4. In this way, when necessary, an external power bank can be used for temporary charging to avoid being unable to open the door in the case of insufficient power. At the same time, because the charging port 11 is facing upward, in order to prevent water from entering, the charging port 11 of this embodiment is sealed by a soft rubber plug 12 when not in use.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
