Description
Technical Field
[0001] This utility model relates to the field of door lock technology, and specifically to a smart lock that reduces signal attenuation. Background Technology
[0002] Smart locks are improvements upon traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. Spherical smart locks have spherical inner and outer handles (lock shanks) and are typically installed on wooden, steel, aluminum alloy, and plastic doors.
[0003] With the development of smart technology, to facilitate users' remote control of smart door locks via mobile phones, an antenna for receiving mobile phone signals is usually installed inside the smart door lock. However, since the outer shell of the door lock is generally made of metal, it has a significant impact on signal transmission. The signal emitted by the mobile phone will be greatly attenuated after passing through the outer shell of the door lock. As a result, users can only operate the smart door lock by mobile phone when they are close to it, which cannot meet normal usage needs. On the other hand, replacing the antenna with a more penetrating antenna would increase the manufacturing cost of the smart door lock and may also increase the size of the door lock, making it inconvenient for users to hold.

[0035] like Figure 1-9 As shown, a smart lock for reducing signal attenuation includes,
[0036] The front lock 10 includes a front lock body 101, a fingerprint module 102, an antenna 103, a keypad 104, a lock cylinder structure 105, and a PCB board 106. The front lock body 101 has an opening, and the PCB board 106 is disposed in the opening and fixedly connected to the front lock body 101. The keypad 104 is mounted on the front end of the PCB board and has a first mounting hole. The fingerprint module 102 is at least partially disposed in the first mounting hole and forms a gap with the first mounting hole. The antenna 103 is installed in the gap. The lock cylinder structure 105 is disposed in the front lock body 101. The fingerprint module 102, the antenna 103, the keypad 104, and the lock cylinder structure 105 are communicatively connected to the PCB board 106.
[0037] One end of the connecting rod 20 extends into the rear end of the front lock body 101 and is structurally connected to the lock cylinder 105.
[0038] The rear lock 30 includes a rear lock body 301 and a Hall module 302. The front end of the rear lock body 301 is fixedly connected to the other end of the connecting rod 20. The Hall module 302 is installed at the rear end of the rear lock body 301 and is communicatively connected to the lock cylinder structure 105. The lock cylinder structure 105 is adapted to lock or release the connecting rod under the control of the fingerprint module 102, the password disk 104, or the Hall module 302.
[0039] This invention utilizes a fingerprint module 102 and a keypad 104 to allow users to control the opening and closing of the ball lock in different ways, preventing situations where the user cannot unlock the lock if the keypad 104 or fingerprint module 102 fails. An antenna 103 connects the PCB board 106 to an external control terminal, such as a mobile phone, enabling remote control of the smart lock's opening and closing. The keypad 104 is mounted on the PCB board 106, with a first mounting hole for the fingerprint module 102. This design fully utilizes the space of the front lock body 101, avoiding an increase in its size, and provides space for the antenna 103. The antenna 103 no longer needs to be installed inside the front lock body 101; the signal can be directly received or transmitted by the antenna 103 without interference from the front lock body 101 housing, effectively improving the antenna's efficiency and increasing the remote operation distance. Furthermore, a Hall effect module 302 allows users to control the lock cylinder structure 105 to open or close according to their needs, protecting user privacy.
[0040] Preferably, in this embodiment, the lock cylinder structure 105 is provided with a keyhole 1051 for inserting a key, so as to be suitable for unlocking or locking the lock cylinder structure 105 by controlling the key. The front lock body 101 is provided with a notch corresponding to the position of the keyhole.
[0041] There are three ways to unlock the door. The first method involves inserting a key into the keyhole to unlock the lock cylinder structure 105. The front lock body 101 then rotates the connecting rod 20, which in turn causes the bolt (located in the middle of the connecting rod 20, a common lock structure, and will not be described in detail here) to disengage from the door frame, thus unlocking the door and separating the door panel from the frame, thereby opening the door. The second method involves receiving correct fingerprint information from the fingerprint module 102 to unlock the lock cylinder structure 105. The front lock body 101 then rotates the connecting rod 20, which in turn causes the bolt to disengage from the door frame, thus unlocking the door and separating the door panel from the frame, thereby opening the door. The third method involves inputting the correct password information via the combination dial 104 to unlock the lock cylinder structure 105. The front lock body 101 then rotates the connecting rod 20, which in turn causes the bolt to disengage from the door frame, thus unlocking the door and separating the door panel from the frame, thereby opening the door.
[0042] When locking the door, the three methods described above can be repeated. For example, in the first method, inserting the key into the keyhole causes the lock cylinder structure 105 to release the connecting rod 20. The lock body 301 then rotates the connecting rod 20, which in turn causes the bolt to insert into the door frame, thus locking the door. Alternatively, receiving the correct fingerprint information from the fingerprint module 102 or the correct password information from the keypad 104 causes the lock cylinder structure 105 to release the connecting rod 20. The lock body 301 then rotates the connecting rod 20, which in turn causes the bolt to insert into the door frame, thus locking the door. Therefore, even if the key is forgotten, the door can be unlocked and locked using the user's fingerprint.
[0043] It is understood that the rear lock body 301 is generally located inside the door, while the front lock body 101 is located outside the door. The lock cylinder structure 105 of this application can be the lock cylinder structure 105 in the prior art, which performs the mechanical action of locking or unlocking, and will not be described in detail here.
[0044] Preferably, in order to minimize the volume occupied by the antenna 103 while meeting the usage requirements of the antenna 103, the antenna 103 is arranged in an arc shape that adapts to the outside of the fingerprint module 102 in this embodiment.
[0045] Furthermore, to make full use of space, in this embodiment, a second mounting hole is also provided on the PCB board 106 at the position corresponding to the first mounting hole. The fingerprint module 102 is at least partially placed in the second mounting hole, thereby making reasonable use of the space inside the front lock body 101. At the same time, to prevent the fingerprint module 102 from being pressed into the front lock body 101 when the user presses it, in this embodiment, a boss 1021 adapted to the first mounting hole is formed on the outer side of the portion of the fingerprint module 102 placed inside the first mounting hole. The rear end of the boss 1021 abuts against the PCB board 106. With this configuration, when the user uses the fingerprint module 102, the protrusion 1021 can abut against the PCB board 106 to prevent the fingerprint module 102 from being pressed into the front lock body 101. At the same time, the antenna 103 is installed at the front end of the protrusion 1021 to separate the PCB board 106 from the antenna 103, thereby preventing the PCB board 106 from interfering with the antenna 103 during use. In addition, a through hole is provided on the protrusion 1021, through which the antenna 103 passes and connects directly to the PCB board 106 to reduce signal attenuation during transmission.
[0046] Meanwhile, to prevent external moisture and dust from entering the front lock body 101 and causing corrosion to the PCB board 106 and antenna 103, a touch screen 107 is also provided on the surface of the keypad 104 in this embodiment. The touch screen 107 can block the opening while ensuring that the user can touch the keypad 104, and will not obstruct the antenna 103 from collecting or transmitting signals. In order to allow the user to contact the fingerprint module 102, an extension hole is provided on the part of the touch screen 107 corresponding to the fingerprint module 102 for the fingerprint module 102 to extend out. At the same time, the inner side of the extension hole is set to fit against the outer side of the fingerprint module 102 to prevent moisture from entering through the gap between them.
[0047] Specifically, there are multiple numeric keys arranged in a ring around the first mounting hole.
[0048] Preferably, the Hall module 302 includes a substrate 3021, a rotating shaft 3022, a rotary switch 3023, a magnet 3024, and a plurality of Hall switches 3025. The substrate 3021 is fixedly disposed inside the rear lock body 301. One end of the rotating shaft 3022 is rotatably mounted inside the rear lock body 301, and the other end is placed outside the rear lock body 301 and the rotary switch 3023 is mounted thereon. One end of the rotating shaft 3022 placed inside the rear lock body 301 passes through the substrate 3021 and is mounted with the magnet 3024. The plurality of Hall switches 3025 are mounted on the side of the substrate 3021 facing the magnet 3024 and are radially evenly arranged with the rotating shaft 3022 as the center.
[0049] Specifically, in this embodiment, the ball lock has three usage modes, namely normally open mode and locked mode, and a Hall switch 3025 is provided for each of the two modes;
[0050] When the normally open mode needs to be activated, the rotary switch 3023 is rotated, which in turn rotates the magnet 3024 via the shaft 3022 to the corresponding Hall switch 3025 position, thereby unlocking the lock cylinder structure 105. The front lock body 101 can drive the connecting rod 20 to rotate, and the connecting rod 20 can drive the bolt to disengage from the door frame of the door structure, thus unlocking the door and separating the door panel from the door frame, thereby opening the door. When the locked mode needs to be activated, the magnet 3024 needs to be rotated to the corresponding Hall switch 3025 position, which causes the lock cylinder structure 105 to release the connecting rod 20. Only the rear lock body 301 can drive the connecting rod 20 to rotate, and the connecting rod 20 can drive the bolt to insert into the door frame of the door structure, thereby locking the door and ensuring the user's privacy.
[0051] In addition, to ensure the normal use of the ball lock after a power outage, this embodiment also includes a battery module 303. The battery module 303 includes a battery box 3031 disposed in the rear lock body 301 and a storage battery installed in the battery box 3031. The storage battery is electrically connected to the fingerprint module 102, the antenna 103, the password disk 104 and the lock cylinder structure 105.
[0052] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
