Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically relating to a padlock. Background Technology

[0002] Padlocks are a traditional type of lock used in many aspects of daily life. Currently, commonly used padlocks are typically mechanical, consisting of a lock body, a shackle on the lock body, a lock cylinder inside the lock body connected to the shackle, and a keyhole at the bottom of the lock body. To unlock, the key is inserted into the keyhole and the lock cylinder is turned, opening the shackle and unlocking the lock. The structure is simple. However, if the operator forgets to bring the key, the lock cannot be opened, affecting work progress. In addition, there are NFC padlocks. NFC technology allows devices to exchange data when they are close to each other. It evolved from contactless radio frequency identification (RFID) and interconnection technologies. By integrating a contactless card reader, contactless card, and point-to-point communication functions onto a single chip, it enables applications such as mobile payment, electronic ticketing, access control, mobile identity recognition, and anti-counterfeiting using mobile terminals. Compared to RFID technology, it has advantages such as high security, low cost, high bandwidth, and low power consumption. The ease of use and security of NFC technology have led to its increasingly widespread application in locks. The introduction of NFC technology has led to the gradual phasing out of mechanical lock cylinders, but it has also brought a problem: although NFC technology is very mature, its reliability is still not high enough compared to mechanical lock cylinders. Once the NFC device fails, there is a risk that the lock cannot be opened, causing unnecessary trouble and losses to users. Utility Model Content

[0028] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0029] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0030] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0031] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0032] This utility model embodiment provides a padlock 100, such as Figures 1 to 4 As shown, the padlock 100 includes a lock body 1 and a lock beam 2, a lock pin 3, a locking element 4, a mechanical unlocking element 5, and an electronic unlocking element 6 disposed on the lock body 1.

[0033] The locking beam 2 has a locking position 21. The locking pin 3 is connected to the locking member 4, and the locking member 4 is movably connected to the lock body 1. When the locking member 4 moves relative to the lock body 1, it can cause the locking pin 3 to engage or disengage from the locking position 21. Understandably, when the locking pin 3 engages in the locking position 21, the locking beam 2 is fixed, and the padlock 100 is in a locked state. When the locking pin 3 disengages from the locking position 21, the locking beam 2 is released, and the padlock 100 is in an unlocked state. Therefore, by controlling the movement of the locking member 4 relative to the lock body 1, the state of the locking pin 3 can be controlled accordingly to perform the unlocking operation.

[0034] The locking component 4 is equipped with a first actuating component 41 and a second actuating component 42. The output shaft of the mechanical unlocking component 5 is equipped with a first actuating component 51, and the output shaft of the electronic unlocking component 6 is equipped with a second actuating component 61. The rotation trajectory of the first actuating component 51 intersects with the first actuating component 41, and the rotation trajectory of the second actuating component 61 intersects with the second actuating component 42. The mechanical unlocking component 5 is unlocked using a mechanical key, and the electronic unlocking component 6 is unlocked using NFC technology.

[0035] Specifically, a locking element 4 is provided to connect with the locking pin 3. The locking element 4 is equipped with a first actuating element 41 and a second actuating element 42. When unlocking is required, either a mechanical unlocking element 5 or an electronic unlocking element 6 can be selected for the unlocking operation. When the mechanical unlocking element 5 is selected for the unlocking operation, the mechanical unlocking element 5 drives the first actuating element 51 to rotate. During the rotation of the first actuating element 51, the first actuating element 41 can be moved, thereby causing the locking element 4 to control the locking pin 3 to move to the disengaged position 21 for the unlocking operation. When the electronic unlocking element 6 is selected for the unlocking operation, the electronic unlocking element 6 drives the second actuating element 6... When the second actuating member 61 rotates, it can drive the second actuating member 42 to move, thereby driving the locking member 4 to control the locking pin 3 to move out of the locking position 21 for unlocking. This allows the padlock 100 to integrate mechanical and electronic unlocking operations, thus increasing the unlocking methods. Furthermore, by setting the locking member 4 between the mechanical unlocking member 5, the electronic unlocking member 6, and the locking pin 3, the mechanical unlocking member 5 and the electronic unlocking member 6 do not act directly on the locking pin 3. Instead, they apply force to the locking member 4 to drive and control the unlocking of the locking pin 3. This reduces the stress on the locking pin 3, effectively prevents damage to the locking pin 3, and improves its service life.

[0036] In some embodiments, such as Figure 3 and Figure 4As shown, the locking member 4 is rotatably mounted on the lock body 1. The first actuating member 41 and the second actuating member 42 are disposed on opposite sides of the locking member 4, and the first actuating member 51 and the second actuating member 61 are located on opposite sides of the first actuating member 41 and the second actuating member 42. Each of the first actuating member 41 and the second actuating member 42 has a first side and a second side respectively. The first side of the first actuating member 41 and the first side of the second actuating member 42 are on the same side, and the second side of the first actuating member 41 and the second side of the second actuating member 42 are on the same side. However, the first side of the first actuating member 41 and the second side of the second actuating member 42 are opposite sides. Therefore, in this embodiment, the first actuating member 51 is located on the first side of the first actuating member 41, and the second actuating member 61 is located on the second side of the second actuating member 42, so that the first actuating member 51 and the second actuating member 61 are located on opposite sides of the first actuating member 41 and the second actuating member 42. On opposite sides, the mechanical unlocking component 5 drives the first actuating component 51 to rotate in the same direction as the electronic unlocking component 6 drives the second actuating component 61 to rotate. Thus, when the first actuating component 51 drives the first actuating component 41 to rotate, the second actuating component 61 is located behind the second actuating component 42 in the direction of rotation. Therefore, the second actuating component 61 will not obstruct the rotation of the locking component 4 and its second actuating component 42. Similarly, when the electronic unlocking component 6 drives the second actuating component 61 to rotate and drives the second actuating component 42 to rotate, the first actuating component 51 is located behind the first actuating component 41 in the direction of rotation. Therefore, the first actuating component 51 will not obstruct the rotation of the locking component 4 and its first actuating component 41. Therefore, by setting the first action member 51 and the second action member 61 at specific positions relative to the first actuating member 41 and the second actuating member 42, on the one hand, the mechanical unlocking member 5 and the electronic unlocking member 6 can smoothly drive the locking pin 3 to perform the unlocking operation, and on the other hand, the mechanical unlocking member 5 and the electronic unlocking member 6 will not cause structural interference to each other, thus affecting the unlocking operation of the locking pin 3. It has the characteristics of simple structure and convenient operation.

[0037] In some embodiments, such as Figure 4 As shown, the first actuating member 41 and the second actuating member 42 are arranged symmetrically around the locking member 4, so that the locking member 4 is subjected to uniform force and can rotate in a consistent manner under the drive of the mechanical unlocking member 5 or the electronic unlocking member 6, and facilitates the assembly of the functional parts of the mechanical unlocking member 5 and the electronic unlocking member 6.

[0038] In some embodiments, such as Figure 4As shown, both the first actuating member 41 and the second actuating member 42 include an actuating body 411. The actuating body 411 is a first protrusion structure formed by extending outward from the side wall of the locking member 4. The first actuating member 51 is a second protrusion structure formed by extending outward from the side wall of the output shaft of the mechanical unlocking member 5. The second actuating member 61 is a third protrusion structure formed by extending outward from the side wall of the output shaft of the electronic unlocking member 6. Understandably, by having the first actuating member 41 and the second actuating member 42 protrude outwards from the side wall of the locking member 4 to form a raised structure, in conjunction with the first actuating member 51 protruding outwards from the side wall of the mechanical unlocking member 5 to form a raised structure, and the second actuating member 61 protruding outwards from the side wall of the electronic unlocking member 6 to form a raised structure, sufficient clearance can be provided between the mechanical unlocking member 5 and the electronic unlocking member 6 relative to the locking member 4, avoiding structural interference between them. When the mechanical unlocking member 5 drives the first actuating member 51 to rotate, the first actuating member 51 can rotate until it abuts against the first actuating member 41 and then continue to rotate until it is offset. When the electronic unlocking member 6 drives the second actuating member 61 to rotate, the second actuating member 61 can rotate until it abuts against the second actuating member 42 and then continue to rotate until it is offset. Thus, the locking pin 3 rotates along a preset path to perform the unlocking operation.

[0039] In some embodiments, such as Figure 4 As shown, the width of the actuating body 411 near the locking member 4 is greater than the width of the end away from the locking member 4, and the end of the actuating body 411 away from the locking member 4 is arc-shaped. The width of the first actuating member 51 near the mechanical unlocking member 5 is greater than the width of the end away from the mechanical unlocking member 5, and the end of the first actuating member 51 away from the mechanical unlocking member 5 is arc-shaped. The width of the second actuating member 61 near the electronic unlocking member 6 is greater than the width of the end away from the electronic unlocking member 6, and the end of the second actuating member 61 away from the electronic unlocking member 6 is arc-shaped. This allows the actuating members to smoothly abut or stagger each other when acting on the actuating member, improving the tactile feel when unlocking and locking.

[0040] In some embodiments, such as Figure 2 and Figure 3As shown, the locking element 4 includes a locking shaft 43 and a rotating element 44 connected to the locking shaft 43. The locking shaft 43 is connected to the locking pin 3, and the rotating element 44 is rotatably mounted on the lock body 1. The first actuating element 41 and the second actuating element 42 are mounted on the rotating element 44. A first reset elastic element 45 is provided between the rotating element 44 and the lock body 1, and a second reset elastic element 46 is provided between the locking shaft 43 and the lock body 1. The system comprises a locking shaft 43 connected to the locking pin 3, and a first actuating element 41 and a second actuating element 42 mounted on a rotating component 44 connected to the locking shaft 43. A mechanical unlocking component 5 or an electronic unlocking component 6 drives the rotating component 44 to rotate, thereby rotating the locking shaft 43 and consequently the locking pin 3 to disengage from the locking position 21 for unlocking. When locking is required, the first and second reset elastic elements 45 and 46 on the rotating component 44 and the locking shaft 43 cooperate to restore the locking component 4 to its original state, causing the locking pin 3 to rotate and engage in the locking position 21 to restore the locking state. The cooperation of the two reset elastic elements increases the force, allowing the locking pin 3 to smoothly return to the locking state under elastic force. Specifically, both the first reset elastic element 45 and the second reset elastic element 46 are torsion springs. Furthermore, since the locking shaft 43 needs to control the locking and unlocking of the locking pin 3, the locking shaft 43 is subjected to a large stress, and needs to be adapted to a shape and structure with high structural strength, or to undergo surface stress treatment, etc. The rotating component 44 needs to cooperate with the mechanical unlocking component 5 and the electronic unlocking component 6 for driving, and has high structural precision requirements. Therefore, by setting the locking shaft 43 and the rotating component 44 as separate connection structures, the corresponding design and processing can be carried out according to the structural characteristics of the two. Specifically, in this embodiment, the structural size of the locking shaft 43 is larger than the structural size of the rotating component 44, thereby achieving the required structural strength of the locking shaft 43 without affecting the structural precision of the rotating component 44, and reducing the overall structural size of the locking component 4.

[0041] In some embodiments, the locking shaft 43 is detachably connected to the rotating member 44. The locking shaft 43 can be detachably connected to the rotating member 44 via a plug-in connection, a threaded connection, or other means, without particular limitation. Since the locking shaft 43 and the rotating member 44 are the main force-bearing transmission components inside the padlock 100, their detachable connection facilitates maintenance and repair of the padlock 100.

[0042] In some embodiments, such as Figure 2 and Figure 3As shown, locking positions 21 are provided on both sides of the locking beam 2, and the two ends of the locking pin 3 respectively engage with the two locking positions 21. The locking pin 3 has two locking ends, corresponding to the two locking positions 21 of the locking beam 2, thus forming two locking points, thereby improving the tensile strength of the padlock 100 and further enhancing its security.

[0043] In some embodiments, such as Figure 2 As shown, the lock beam 2 has a connecting portion 22 and a locking portion 23 connected to the connecting portion 22. The connecting portion 22 is connected to the lock body 1 via an elastic body 7, and both the connecting portion 22 and the locking portion 23 are provided with a locking position 21. Specifically, the elastic body 7 can be a spring. By providing this spring at the connecting portion 22, when the locking pin 3 disengages from the locking position 21, the lock beam 2 pops out under the elastic action of the spring, causing the locking portion 23 to disengage from the lock body 1 and enter an unlocked state. Specifically, the locking position 21 is a notch structure formed on the lock beam 2.

[0044] In some embodiments, such as Figure 2 As shown, the electronic unlocking device 6 includes an NFC module 62 and a motor 63 electrically connected to the NFC module 62. The NFC module 62 controls the starting and stopping of the motor 63, and the output shaft of the motor 63 is provided with a second actuating member 61. Specifically, when an NFC adapter is brought close to the NFC module 62 to power the motor 63 and issue an unlocking command, the motor 63 rotates, driving the second actuating member 61 to rotate, thereby causing the locking member 4 to release the locking pin 3 from the locking beam 2, thus unlocking the device.

[0045] In some embodiments, such as Figure 2 As shown, the locking element 4 is vertically disposed within the lock body 1, the first actuating element 41 and the second actuating element 42 are horizontally disposed on the locking element 4, the mechanical unlocking element 5 and the electronic unlocking element 6 are disposed on both sides of the locking element 4 and vertically disposed within the lock body 1, and the locking pin 3 is horizontally disposed within the locking element 4 and can rotate to engage with the locking position 21 or disengage from the locking position 21.

[0046] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
