Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to an electronic padlock. Background Technology

[0002] Electronic padlocks are a new type of lock that combines electronic technology, using smart chips, cryptographic algorithms, and wireless communication technology to achieve secure locking and unlocking. They can be used in lockers, luggage, and other similar applications. However, electronic padlocks typically contain batteries, circuit boards, and other electronic components. Since they usually use a motor to drive the bolt, locking the hook in a slot, the gap between the bolt and the bolt hole is prone to water ingress. Outdoor rain can easily cause water damage, leading to short circuits, rust, and corrosion in the internal circuitry, resulting in functional failure and low reliability. Utility Model Content

[0040] This utility model proposes an electronic padlock.

[0041] In the embodiments of this utility model, such as Figures 1 to 10 As shown, the electronic padlock includes a lock body 10 and a pendant 20. The lock body 10 includes a first housing 11, a second housing 12, a latch 15, and a sealing ring 14. The first housing 11 and the second housing 12 enclose a mounting cavity 101, a first lock hole 102, and a first through hole 105. One end of the first through hole 105 communicates with the mounting cavity 101, and the other end penetrates the wall of the first lock hole 102. The latch 15 is installed in the mounting cavity 101 and has a locked state in which it extends into the first lock hole 102 through the first through hole 105 and an unlocked state in which it exits the first lock hole 102. The sealing ring 14 is disposed between the first housing 11 and the second housing 12 and surrounds the mounting cavity 101. The sealing ring 14 has a first sealing part 141 at the position corresponding to the first through hole 105, and the first sealing part 141 is sleeved on the outside of the latch 15.

[0042] The pendant 20 has a limiting end 231 and a snap-fit ​​end 221. The limiting end 231 is installed on the lock body 10, and the snap-fit ​​end 221 is detachably inserted into the first lock hole 102 and has a slot 222 that engages with the lock tongue 15.

[0043] Specifically, the lock body 10 also includes a drive mechanism 16, an identification module, a main control board, and a battery 171. The battery 171, drive mechanism 16, and identification module are all electrically connected to the main control board. The drive mechanism 16, main control board, and battery 171 are all located in the mounting cavity 101. The battery 171 supplies power to the drive mechanism 16, identification module, and main control board. The drive mechanism 16 is drive-connected to the bolt 15 to drive its movement. The identification module is used to identify unlocking signals. The identification module can be an NFC module (Near Field Communication), a fingerprint recognition module 172, or a Bluetooth module, etc. The specific cooperation structure between the drive mechanism 16 and the bolt 15, as well as the circuit structure and control principle between the drive mechanism 16, identification module, main control board, and battery 171, can refer to existing technologies and will not be elaborated further here.

[0044] At least one of the first housing 11 and the second housing 12 has a groove structure formed at a corresponding position to enclose an installation cavity 101, a first locking hole 102, and a first through hole 105 when the first housing 11 and the second housing 12 are closed together. During installation, the locking tongue 15 and sealing ring 14 can be installed on one of the first housing 11 and the second housing 12 first, and then the two can be closed together. The first sealing part 141 is sleeved on the outside of the locking tongue 15, that is, the first sealing part 141 has a through hole through which the locking tongue 15 passes. The first sealing part 141 and the locking tongue 15 are tightly fitted to seal the gap between the first sealing part 141 and the locking tongue 15. That is, the gap between the first through hole 105 and the locking tongue 15 can be sealed by the first sealing part 141, which can effectively prevent water leakage between the first through hole 105 and the locking tongue 15. The first housing 11 and the second housing 12 can be welded or locked with screws.

[0045] The hanging component 20 can be a rigid metal part, such as a U-shaped rod, or a steel rope structure. In use, the limiting end 231 is relatively fixed to the lock body 10 (relative to the locking end 221), meaning the limiting end 231 can be either non-removably fixed to the lock body 10 or detachably installed on the lock body 10. When the locking end 221 is inserted into the first lock hole 102 and the bolt 15 is in the locked state, the bolt 15 engages in the slot 222 of the locking end 221, thereby restricting the locking end 221 within the first lock hole 102 and preventing it from dislodging. At this time, both ends of the hanging component 20 are fixed to the lock body 10, achieving locking. When the bolt 15 is in the unlocked state, the bolt 15 exits the slot 222 of the locking end 221, allowing the locking segment to be removed from the first lock hole 102, thus unlocking.

[0046] The lock body 10 also includes a charging structure, which is electrically connected to the main control board and used to connect to an external power source to charge the battery 171. The charging structure can be a charging interface (e.g., a Type-C interface), a wireless charging coil, or an electrical connector with two charging probes.

[0047] The lock body 10 of this utility model adopts a structure in which a first housing 11 and a second housing 12 enclose a mounting cavity 101, a first lock hole 102, and a first through hole 105. A sealing ring 14 is provided between the first housing 11 and the second housing 12, surrounding the mounting cavity 101. A first sealing part 141 is provided on the sealing ring 14 at a position corresponding to the first through hole 105, so that the first sealing part 141 is sleeved on the outside of the lock tongue 15. In this way, the sealing ring 14 can seal the gap between the first housing 11 and the second housing 12, preventing water from entering the mounting cavity 101 through the gap between the first housing 11 and the second housing 12 and causing water ingress and short circuit in the circuit structure of the mounting cavity 101. At the same time, the setting of the first sealing part 141 can not only ensure the normal movement of the lock tongue 15 to achieve locking and unlocking, but also effectively seal the gap between the first through hole 105 and the lock tongue 15, preventing water leakage between the first through hole 105 and the lock tongue 15, effectively improving the waterproof performance of the electronic padlock and reducing the risk of malfunction due to water ingress.

[0048] In some embodiments, the pendant 20 includes a metal rope 21 and a snap-fit ​​member 22 mounted on the end of the metal rope 21, the snap-fit ​​member 22 having a snap-fit ​​groove 222. The metal rope 21 can be bent, making it more versatile and convenient to use. Optionally, the pendant 20 also includes a limiting member 23, which is mounted on the end of the metal rope 21 away from the snap-fit ​​member 22, and has a limiting end 231. This facilitates the installation structure on the limiting member 23, making it easier to assemble the electronic padlock. Of course, in other embodiments, the end of the metal rope 21 away from the snap-fit ​​member 22 can also be directly fixed to the first housing 11 or the second housing 12.

[0049] In some embodiments, the slot 222 is an annular shape extending circumferentially along the snap-fit ​​end 221, that is, the slot 222 is an annular groove, which facilitates processing and forming. When the pendant 20 uses a metal rope 21, it is not necessary to determine the position of the slot 222 during the locking process, which can realize blind insertion and is convenient for users.

[0050] In some embodiments, the lock body 10 further includes an elastic element 192, which abuts against the side of the latch 15 facing away from the first lock hole 102. That is, under the action of the elastic element 192, the latch 15 tends to move towards the first lock hole 102. For example, when the locking end 221 is outside the first lock hole 102, the latch 15 moves to the locked state under the action of the elastic element 192. Optionally, the portion of the locking end 221 near its end face is tapered. That is, during the insertion of the locking end 221 into the first lock hole 102, the tapered portion can abut against the end of the latch 15 located inside the first lock hole 102, thereby forcing the latch 15 back into the first through hole 105, facilitating locking by the user.

[0051] In some embodiments, at least one of the first housing 11 and the second housing 12 is provided with a first groove 111, which is located between the two ends of the first through hole 105, and the first sealing part 141 is embedded in the first groove 111. That is, the first groove 111 is spaced apart from the two ends of the first through hole 105, so that the first sealing part 141 can be stably installed in the first groove 111, avoiding displacement of the first sealing part 141 due to the movement of the locking tongue 15, and improving the sealing performance between the first sealing part 141 and the locking tongue 15.

[0052] In some embodiments, at least one of the first housing 11 and the second housing 12 is provided with a first annular groove 112. The first annular groove 112 surrounds the mounting cavity 101 and passes through the first groove 111. The sealing ring 14 is disposed in the first annular groove 112. This facilitates the positioning and installation of the sealing ring 14, and also confines the sealing ring 14 to the first annular groove 112 to prevent the sealing ring 14 from shifting during installation, thus ensuring reliable installation.

[0053] In some embodiments, the latch 15 is provided with a groove 151 extending axially along the first through hole 105. A drive mechanism 16 is disposed within the mounting cavity 101 and has a lever extending into the groove 151. Specifically, the drive mechanism 16 includes a motor and a reduction mechanism disposed within the motor. The lever is disposed within the reduction mechanism and spaced apart from the motor's axis, i.e., the lever is eccentrically positioned. The lever has a first position close to the first through hole 105 and a second position away from the first through hole 105. When the lever moves from the first position to the second position, it abuts against the groove wall of the groove 151 away from the first through hole 105, thereby driving the latch 15 to move towards the unlocked state. When the lever is in the second position, the latch 15 is in the unlocked state. When the lever moves from the second position to the first position, the latch 15 moves towards the locked state under the action of the elastic member 192. When the latch 15 is in the first position, the latch 15 is in the locked state. This structure is simple and reliable, which helps reduce production costs. Of course, in other embodiments, when the lever moves from the second position to the first position, the lever can also abut against the groove wall of the first through hole 105 near the groove 151, so as to drive the locking tongue 15 to move towards the locked state.

[0054] In some embodiments, a second locking hole 103 is formed between the first housing 11 and the second housing 12. The second locking hole 103 is located outside the sealing ring 14, and the limiting end 231 is installed inside the second locking hole 103. In actual use, the snap-fit ​​end 221 can be detached to meet basic usage requirements. The limiting end 231 mainly plays a fixing role. By placing the limiting end 231 outside the sealing ring 14, the influence between the limiting end 231 and the sealing ring 14 can be reduced, and the sealing effect of the sealing ring 14 can be guaranteed to be better.

[0055] In some embodiments, a second through hole 106 is formed between the first housing 11 and the second housing 12. One end of the second through hole 106 communicates with the mounting cavity 101, and the other end penetrates the wall of the second lock hole 103. The lock body 10 also includes a first locking pin 131 and a first spring 133. The first locking pin 131 is movably installed in the second through hole 106 and extends into the second lock hole 103. The sealing ring 14 has a second sealing portion 142 corresponding to the position of the second through hole 106. The second sealing portion 142 is sleeved on the first locking pin 131. The limiting end 231 is provided with a limiting groove 232 that engages with the first locking pin 131. The first spring 133 abuts against the side of the first locking pin 131 away from the second lock hole 103. The limiting end 231 has a guide surface 233 extending to the end face. Specifically, the second sealing part 142 is sleeved outside the first locking pin 131, that is, the second sealing part 142 has a through hole, the first locking pin 131 passes through the through hole, and the second sealing part 142 and the first locking pin 131 are tightly fitted to seal the gap between the second sealing part 142 and the first locking pin 131.

[0056] During installation, first assemble the lock body 10, so that the first locking pin 131 and the first spring 133 are installed between the first housing 11 and the second housing 12. At this time, the first locking pin 131 extends into the second lock hole 103 under the action of the first spring 133. During the process of inserting the limiting end 231 into the second lock hole 103, the guide surface 233 abuts against the end of the first locking pin 131, causing the first locking pin 131 to retract into the second through hole 106 until the limiting end 231 is installed in place. Then, under the action of the first spring 133, the first locking pin 131 extends into the second lock hole 103 again and is engaged in the limiting groove 232, thereby realizing the installation of the limiting end 231. In this way, the lock body 10 can be assembled first, and the hanging part 20 can be installed last, which is more convenient. Since the user does not need to disassemble the limiting end 231 during use, the first locking pin 131 and the second sealing part 142 are relatively stationary, which can ensure the sealing performance.

[0057] Of course, in other embodiments, the inner wall of the second lock hole 103 is provided with a limiting groove, and the side of the limiting end 231 is provided with a locking protrusion. During installation, the limiting end 231 is first installed on the first housing 11 at the position corresponding to the second lock hole 103, so that the locking protrusion corresponds to the position of the limiting groove. Then, the second housing 12 is covered with the first housing 11, so that the locking protrusion is located in the limiting groove, thereby fixing the limiting end 231 in the second lock hole 103.

[0058] In some embodiments, a third lock hole 104 is formed between the first housing 11 and the second housing 12. The third lock hole 104 is located outside the sealing ring 14. The electronic padlock also includes a hook 30, which includes a mounting section 31 and a hooking section 32 connected to the mounting section 31. The mounting section 31 is rotatably mounted in the third lock hole 104. The hooking section 32 has a retracted state close to the lock body 10 and a suspended state relative to the lock body 10. In the suspended state, the electronic padlock can be suspended on other objects through the hooking section 32, avoiding placing the electronic padlock in places with stains and water, making it convenient for users to use.

[0059] In some embodiments, a third through hole 107 is formed between the first housing 11 and the second housing 12. One end of the third through hole 107 communicates with the mounting cavity 101, and the other end penetrates the wall of the third locking hole 104. The lock body 10 also includes a second locking pin 132 and a second spring 134. The second locking pin 132 is movably mounted in the third through hole 107 and extends into the third locking hole 104. The sealing ring 14 has a third sealing portion 143 corresponding to the position of the third through hole 107. The third sealing portion 143 is sleeved on the second locking pin 132, and the second spring... Spring 134 abuts against the side of the second locking pin 132 away from the third locking hole 104; the mounting section 31 is provided with a second annular groove 311 and an annular limiting part 313. The annular limiting part 313 is located on the side of the second annular groove 311 away from the curved section. The groove wall of the second annular groove 311 near the annular limiting part 313 gradually slopes towards the direction of the annular limiting part 313 in the direction near the groove opening. In the retracted state, the second locking pin 132 is located in the second annular groove 311, and the annular limiting part 313 is used to restrict the mounting section 31 within the third locking hole 104. During installation, the mounting section 31 can be installed first at the corresponding position of the first housing 11 or the second housing 12, and then the first housing 11 and the second housing 12 can be closed together.

[0060] Due to the restriction of the annular limiting part 313, the mounting section 31 is located within the third lock hole 104 in both the retracted and suspended states. In the retracted state, the second locking pin 132 is located within the second annular groove 311. When the mounting section 31 is pulled outward from the third lock hole 104, the second locking pin 132 can move into the third through hole 107 under the action of the groove wall of the second annular groove 311 near the annular limiting part 313, until the second locking pin 132 is completely disengaged from the second annular groove 311. After the mounting section 31 moves a certain distance outward from the third lock hole 104, it cannot be completely disengaged from the third lock hole 104 due to the restriction of the annular limiting part 313. At this time, the hook 30 can be rotated to the suspended state. In this way, the hook 30 can be kept relatively stably in the retracted state through the cooperation of the second annular groove 311 and the second locking pin 132, preventing the hook 30 from swinging randomly and affecting the normal use of the electronic padlock.

[0061] In some embodiments, the mounting section 31 is provided with a third annular groove 312, which is located on the side of the second annular groove 311 away from the curved section. An annular limiting portion 313 is formed between the third annular groove 312 and the end face of the mounting section 31. At least one of the first housing 11 and the second housing 12 is provided with a limiting protrusion 122, which is at least partially located in the third locking hole 104 and extends into the third annular groove 312. In the suspended state, the limiting protrusion 122 abuts against the groove wall of the third annular groove 312 away from the second annular groove 311. The second locking pin 132 abuts against the portion of the mounting section 31 located between the second annular groove 311 and the third annular groove 312. That is, the limiting protrusion 122 is fixed between the first housing 11 and the second housing 12. When the second locking pin 132 is located in the second annular groove 311, the limiting protrusion 122 is spaced apart from the annular limiting portion 313. Optionally, the mounting section 31 has a clearance plane parallel to the axis of the mounting section 31 and extending from the second annular groove 311 to the third annular groove 312. The clearance plane is not higher than the bottom walls of the second annular groove 311 and the third annular groove 312. In the retracted state, the clearance plane is located on the side of the mounting section 31 opposite to the third through hole 107, and the limiting protrusion 122 is located on the side of the mounting section 31 opposite to the third through hole 107 and is corresponding to the clearance plane. When the mounting section 31 moves outward toward the third locking hole 104 until the limiting protrusion 122 is located in the third annular groove 312, the mounting section 31 can rotate within the third locking hole 104.

[0062] In other embodiments, the groove wall of the third annular groove 312 near the second annular groove 311 gradually tilts towards the direction of the second annular groove 311 in the direction near the groove opening. In the suspended state, the second locking pin 132 is located in the third annular groove 312. That is, when the second locking pin 132 is located in the third annular groove 312, the second locking pin 132 can abut against the annular limiting part 313, thereby preventing the mounting section 31 from coming out of the third locking hole 104. When the mounting section 31 moves into the third locking hole 104 with the second locking pin 132 in the third annular groove 312, the second locking pin 132 can move into the third through hole 107 under the action of the groove wall of the third annular groove 312 near the second annular groove 311 until the mounting section 31 moves to the position of the second locking pin 132 corresponding to the second annular groove 311. The second locking pin 132 extends into the second annular groove 311 under the action of the second spring 134.

[0063] In some embodiments, an insertion hole 108 is also formed between the first housing 11 and the second housing 12. In the retracted state, the end of the hook section 32 away from the mounting section 31 is inserted into the insertion hole 108. This can prevent the hook 30 from rotating in the retracted state, ensure that the hook 30 is stably maintained in the retracted state, and avoid affecting the normal use of the electronic padlock.

[0064] In some embodiments, the lock body 10 further includes a cover plate 18, a fingerprint recognition module 172, and a sealing element 191. The second housing 12 has a mounting groove 121 on the side opposite to the first housing 11. The fingerprint recognition module is disposed within the mounting groove 121. The cover plate 18 covers the mounting groove 121 and has a mounting through hole 181 corresponding to the position of the fingerprint recognition module 172. The sealing element 191 is disposed between the cover plate 18 and the second housing 12. This facilitates the installation of the fingerprint recognition module 172 and ensures the seal between the cover plate 18 and the second housing 12, reducing the risk of water leakage.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
