Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to a front locking structure of an intelligent ball lock and the intelligent ball lock itself. 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. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a front locking structure for an intelligent ball lock that can reduce signal attenuation.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] A front locking structure for a smart ball lock includes a front lock body, a fingerprint module, an antenna, a combination dial, a lock cylinder structure, and a PCB board. The front lock body has an opening, the PCB board is disposed in the opening and fixedly connected to the front lock body, the combination dial is mounted on the front end of the PCB board, and the combination dial has a first mounting hole. The fingerprint module is at least partially disposed in the first mounting hole, forming a gap with the first mounting hole. The antenna is installed in the gap. The fingerprint module, the antenna, the combination dial, and the lock cylinder structure are communicatively connected to the PCB board. The lock cylinder structure is disposed in the front lock body and is adapted to unlock or lock under the control of the fingerprint module and the combination dial.

[0007] Furthermore, the antenna is arranged in an arc-shaped thin sheet that adapts to the outside of the fingerprint module.

[0008] Furthermore, the antenna is made of metal.

[0009] Furthermore, the PCB board has a second mounting hole at the position corresponding to the first mounting hole, and the fingerprint module is at least partially placed in the second mounting hole.

[0010] Furthermore, the fingerprint module has a boss that fits the first mounting hole on the outer side of the portion inside the first mounting hole. The rear end of the boss abuts against the PCB board, and the antenna is installed at the front end of the boss. A through hole is provided on the boss, and the antenna passes through the through hole to connect with the PCB board.

[0011] Furthermore, the surface of the password disk is provided with a touch screen, and the touch screen is provided with an extension hole for the fingerprint module to extend out, the inner side of the extension hole being fitted with the outer side of the fingerprint module.

[0012] Furthermore, the lock cylinder structure is provided with a keyhole for inserting a key, so as to be suitable for unlocking or locking by controlling the moving end of the lock cylinder structure with a key, and the front lock body is provided with a notch corresponding to the keyhole.

[0013] The second objective of this utility model is achieved through the following technical solution:

[0014] A smart ball lock includes a rear lock body, a connecting rod, and a front lock structure of the aforementioned smart ball lock.

[0015] Beneficial effects:

[0016] This invention utilizes a fingerprint module and a keypad 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 or fingerprint module malfunctions. An antenna connects the PCB board to an external control device, such as a mobile phone, enabling remote control of the smart lock. The keypad is mounted on the PCB board with a first mounting hole for the fingerprint module. This design maximizes space in the front lock body, avoiding an increase in its size, and provides space for the antenna. The antenna does not need to be installed inside the front lock body; the signal can be directly received or transmitted by the antenna without interference from the front lock body housing or the keypad, effectively improving antenna efficiency and increasing the remote operation distance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1-6 As shown, a front locking structure of a smart ball lock includes a front lock body 101, a fingerprint module 102, an antenna 103, a combination dial 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 combination dial 104 is installed at the front end of the PCB board 106 and has a first mounting hole. The fingerprint module 102 is at least partially disposed in the first mounting hole, forming a gap with the first mounting hole. The antenna 103 is installed in the gap. The fingerprint module 102, the antenna 103, the combination dial 104, and the lock cylinder structure 105 are communicatively connected to the PCB board 106. The lock cylinder structure 105 is disposed in the front lock body 101 and is adapted to unlock or lock under the control of the fingerprint module 102 and the combination dial 104.

[0031] 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, thus preventing the user from being unable to 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 users to remotely control the opening and closing of the smart lock. 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. This eliminates the need for the antenna 103 to be installed inside the front lock body 101, allowing the signal to be directly received or transmitted by the antenna without interference from the front lock body 101 housing or the keypad 104. This effectively improves the efficiency of the antenna 103 and increases the remote operation distance.

[0032] In order to meet the usage requirements of antenna 103 and minimize the volume occupied by antenna 103, in this embodiment, antenna 103 is arranged in an arc-shaped thin sheet that adapts to the outside of fingerprint module 102. At the same time, in order to reduce production costs, antenna 103 is made of metal in this embodiment.

[0033] In addition, to make full use of the space, in this embodiment, a second mounting hole is provided on the PCB board 106 at the position corresponding to the first mounting hole, and 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.

[0034] Meanwhile, to prevent the fingerprint module 102 from being pressed into the front lock body 101 when the user presses it, in this embodiment, a protrusion 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 protrusion 1021 abuts against the PCB board 106. With this arrangement, 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 directly to the PCB board 106 to reduce signal attenuation during transmission.

[0035] 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.

[0036] Preferably, in order to facilitate the user to control the opening and closing of the smart ball lock even when there is no power, a keyhole 1051 for key insertion is provided on the lock cylinder structure 105 in this embodiment, and a notch is provided on the front lock body 101 at the position corresponding to the keyhole 1051, so that the user can insert the key into the keyhole 1051 to control the action end of the lock cylinder structure 105 to perform unlocking or locking actions.

[0037] In this embodiment, the lock cylinder structure 105 can be a door lock actuator of a common electronic lock, and there is no limitation.

[0038] like Figure 7 As shown, this utility model also discloses an intelligent ball lock, including a rear lock body 301, a connecting rod 20, and the aforementioned intelligent ball lock front lock structure.

[0039] 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.
