[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] This application provides a lock, which can be a door lock, vehicle lock, padlock, floor lock, etc., and this application does not limit it.

[0054] In some embodiments, to enable the communication function of the lock, the lock may be equipped with a coil for near-field communication with a wireless device to transmit energy and / or information. The coil may be used solely for energy transmission, solely for information transmission, or both; this application does not limit this specific use.

[0055] Specifically, when the coil can be used to transmit energy, it can be that the wireless device charges the lock, thus making the lock a passive lock. Alternatively, the lock can reverse-charge the wireless device; this application does not limit this. When the coil is used to transmit information, the information can be lock / unlock commands sent by the wireless device, firmware upgrade packages, etc., or lock / unlock logs sent by the lock, the lock's working status, etc. This application also does not limit this.

[0056] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a lock provided in an embodiment of this application. Figure 2 for Figure 1 The exploded view of the lock shown. The lock may include a housing 100, a locking component 41, a drive assembly 700, a bolt assembly 500, a first circuit board 300, a first electrical connector 31, and an inner cover 200.

[0057] The outer casing 100 is provided with a first through hole 111. A locking member 41 is movably inserted through the first through hole 111, thereby enabling the locking member 41 to move to a locked state to lock other items, and to move to an unlocked state to unlock other items. The locking member 41 is provided with a first sealing ring 43, such as a first rubber sealing ring or a first silicone sealing ring, that mates with the first through hole 111, thereby achieving a first layer of sealing for the interior of the outer casing 100.

[0058] The drive assembly 700 is located inside the housing 100.

[0059] The locking tongue assembly 500 is located inside the housing 100. The locking tongue assembly 500 is connected to the drive assembly 700 so that it can lock or unlock the locking component 41 by being driven by the drive assembly 700. When the locking component 41 needs to lock other items, the drive assembly 700 can drive the locking tongue assembly 500 to lock the locking component 41.

[0060] A first circuit board 300 is mounted inside the housing 100. The first circuit board 300 has a coil for near-field communication to transmit energy and / or information. A first electrical connector 31, such as TYPE-A, TYPE-C, MICRO-B, aviation connector, etc., is mounted on and electrically connected to the first circuit board 300. The first electrical connector 31 is also electrically connected to the drive assembly 700, allowing the wireless device to communicate with the drive assembly 700 via the coil, thereby controlling the drive assembly 700 to drive the latch assembly 500 to control the opening and closing of the lock. An inner cover 200 is mounted inside the housing 100, forming a first cavity and a second through hole 26 communicating with the first cavity. The first circuit board 300 is housed in the first cavity, and the first electrical connector 31 passes through the second through hole 26. The inner cover 200 is also provided with a second waterproof structure (not shown in the figure). The second waterproof structure seals the gap between the second through hole 26 and the first electrical connector 31, thereby achieving a second layer of waterproof protection for the first circuit board 300 through the inner cover 200 and the second waterproof structure. Finally, the waterproof performance of the first circuit board 300 is improved through the double waterproof protection structure.

[0061] The outer casing 100 may include a first housing 11 and a first cover 12. The first housing 11 has a mounting cavity. The first cover 12 is detachably connected to the first housing 11 to close the mounting cavity. For example, the first cover 12 and the first housing 11 may be screwed or snap-fitted together to facilitate maintenance of the internal components of the outer casing 100 by disassembling the first cover 12. The first circuit board 300 and the inner cover 200 are both mounted on the inner wall of the first cover 12.

[0062] The first cover 12 can be located on one side of the outer shell 100 in the thickness direction, so that the area of ​​the first cover 12 is larger, and the area of ​​the coil can also be made larger, so as to increase the coupling area between the coil and the wireless device, thereby further improving the coupling efficiency.

[0063] Of course, in some other embodiments, the first cover 12 and the first housing 11 may also be non-detachably connected and fixed, such as by welding or fusion fixing between the first cover 12 and the first housing 11. This application embodiment does not limit this.

[0064] It is understood that the specific structure of the second waterproof structure can be diverse, such as being formed by the curing of waterproof adhesive, or the second waterproof structure can be a second sealing ring such as a second rubber sealing ring or a second silicone sealing ring, etc., and the embodiments of this application do not limit this.

[0065] Taking the second waterproof structure, including the waterproof adhesive, as an example, please refer to... Figure 3 and Figure 4 , Figure 3 for Figure 1 The diagram shows the assembly of the inner cover parts of the lock. Figure 4 for Figure 3 The exploded view of the inner cover is shown. The inner cover 200 may include a first end face 21 and a third flange 27. The first end face 21 is located on the side of the inner cover 200 opposite to the first cover body 12, and one end opening of the second through hole 26 is located on the first end face 21. The third flange 27 protrudes from the first end face 21, and the second flange 123 is at least partially surrounding the second through hole 26. The second waterproof structure is at least partially located inside the third flange 27.

[0066] During the process of applying or dispensing waterproof adhesive to form the second waterproof structure, the third retaining edge 27 prevents the waterproof adhesive from being applied to other locations, thus avoiding waste, affecting the aesthetics of the inner cover 200, or even affecting the installation or operation of other components. Furthermore, before the waterproof adhesive dries, the third retaining edge 27 can also limit its flow, preventing it from affecting the waterproof performance of the second through hole 26.

[0067] In some embodiments, at least a portion of the inner surface of the third retaining edge 27 is connected to the surface of the third retaining edge 27 away from the first end face 21 by a third guiding slope 28. Furthermore, before the waterproof adhesive at the third retaining edge 27 dries, the waterproof adhesive can flow along the third guiding slope 28 to the inner side of the third retaining edge 27 to seal the gap between the wall of the second through hole 26 and the first electrical connector 31. This not only facilitates the dispensing or coating operation at the second through hole 26, but also allows the dried second waterproof structure to more accurately seal the gap between the wall of the second through hole 26 and the first electrical connector 31.

[0068] In some embodiments, the inner wall of the first cover 12 is provided with a welding portion 124, which passes through the first circuit board 300 and is welded and fixed to the first circuit board 300, so that the coil is attached to the inner wall of the first cover 12. Furthermore, during later use, even if the outer casing 100 is subjected to a large impact, the first circuit board 300 is not easily loosened or displaced. At the same time, since the first circuit board 300 is tightly attached to the first cover 12, the distance between the coil on the first circuit board 300 and the first cover 12 is smaller. Therefore, when the wireless device comes into contact with the first casing 11, the coupling distance between the coil and the wireless device is also smaller, thereby improving coupling efficiency.

[0069] Specifically, the coil can be disposed on the surface of the first circuit board 300 that is attached to the first cover 12. For example, the coil can be directly formed on the surface of the first circuit board 300 that is attached to the first cover 12 by means of printing, etching, etc. Of course, the first circuit board 300 can also be a multilayer board, and the coil is disposed in the middle layer of the first circuit board 300. Alternatively, the coil can be formed on the surface of the first circuit board 300 that is opposite to the first cover 12; this embodiment of the application does not limit this.

[0070] In some embodiments, the welding portion 124 and the first cover 12 can be integrally formed. For example, the welding portion 124 and the first cover 12 can be weldable plastics, such as PP (Polypropylene), PA (Nylon), or PC (Polycarbonate) engineering plastics doped with 5% glass fiber. Furthermore, this achieves welding of the welding portion 124 to the first circuit board 300 without shielding near-field communication between the coil and the wireless device.

[0071] In some embodiments, the inner cover 200 is provided with a third through hole 24 through which the welding part 124 passes. The inner cover 200 is also provided with a third waterproof structure (not shown in the figure), which seals the gap between the third through hole 24 and the welding part 124. Thus, the outer shell 100 can achieve a first layer of waterproofing for the interior of the lock, and the third waterproof structure seals the third through hole 24 to form a second layer of waterproofing for the first circuit board 300. Therefore, the double waterproof structure effectively improves the waterproof performance of the lock for the first circuit board 300.

[0072] The third waterproofing structure may include waterproofing adhesive, or in other words, the third waterproofing structure is formed by the curing of a liquid waterproofing adhesive.

[0073] Correspondingly, the end face of the third through hole 24 may be provided with a second guide slope 25. Along the direction of the third through hole 24 toward the first cavity, the inner diameter of the second guide slope 25 gradually decreases, so that the waterproof adhesive can be transferred to the second guide slope 25 by dispensing or applying waterproof adhesive, so as to dry and form a third waterproof structure.

[0074] Of course, in some other embodiments, the third waterproof structure can also be a third sealing ring, such as a third rubber sealing ring, a third silicone sealing ring, etc., and this application embodiment does not limit this.

[0075] In some embodiments, a fourth waterproof structure (not shown in the figure) is provided on the outer periphery of the inner cover 200, which seals the gap at the connection between the inner cover 200 and the outer shell 100. Thus, the outer shell 100 provides the first layer of waterproofing to the interior of the lock, while the fourth waterproof structure seals the space between the outer shell 100 and the inner cover 200, forming a second layer of waterproofing to the first circuit board 300. This dual waterproof structure effectively improves the lock's waterproof performance to the first circuit board 300.

[0076] In some embodiments, a first retaining edge 121 protrudes from the inner wall of the first cover 12. The first retaining edge 121 surrounds the inner cover 200. The fourth waterproof structure includes a waterproof adhesive, or in other words, the fourth waterproof structure is formed by the curing of a liquid waterproof adhesive. The fourth waterproof structure is at least partially located between the outer periphery of the inner cover 200 and the first retaining edge 121.

[0077] Therefore, during the application of adhesive or waterproof adhesive, on the one hand, it can prevent the waterproof adhesive from being applied to other locations, thereby avoiding waste of the waterproof adhesive, affecting the aesthetics of the inner cover 200, or even affecting the installation or operation of other components; on the other hand, before the waterproof adhesive forming the fourth waterproof structure dries, the first retaining edge 121 can limit and shape the waterproof adhesive forming the fourth waterproof structure, so as to prevent the waterproof adhesive forming the fourth waterproof structure from flowing to other locations, thereby affecting the waterproof performance at the joint between the first cover 12 and the first shell 11.

[0078] In some embodiments, the inner cover 200 may include a first end face 21 and a first flow-guiding slope 22. The first end face 21 is located on the side of the inner cover 200 opposite to the first cover body 12. The first flow-guiding slope 22 is located on the outer peripheral side of the inner cover 200 and is connected to the first end face 21. Along the radially outward direction of the first inner cover 200, the first flow-guiding slope 22 is inclined towards the inner wall of the first cover body 12.

[0079] Therefore, during the dispensing or coating of waterproof adhesive, the circuit board 300 can be placed on the working surface with the first housing 11 facing down and the inner cover 200 facing up. The waterproof adhesive is then transferred between the first guide slope 22 and the first retaining edge 121 via dispensing or coating. The adhesive then fills the gap between the first retaining edge 121 and the outer periphery of the inner cover 200 along the first guide slope 22, thus forming a fourth waterproof structure that seals the gap between the inner cover 200 and the outer shell 100 after drying. It is evident that the first guide slope 22 not only facilitates dispensing or coating operations but also allows the fourth waterproof structure to more accurately seal the gap between the inner cover 200 and the outer shell 100 after drying, thereby improving the waterproof performance of the first circuit board 300.

[0080] Of course, in some other embodiments, the fourth waterproof structure can also be a fourth sealing ring, such as a fourth rubber sealing ring, a fourth silicone sealing ring, etc., and this application embodiment does not limit this.

[0081] The number of first guard edges 121 can be one, or there can be multiple first guard edges 121, such as two, three or four. This application embodiment does not limit this.

[0082] When the number of first guard edges 121 is one, the first guard edge 121 can be a closed ring structure to surround the entire inner cover 200, or the first guard edge 121 can be arc-shaped, such as a superior arc or a inferior arc, to partially surround the inner cover 200.

[0083] When there are multiple first guard edges 121, the multiple first guard edges 121 can be arranged circumferentially around the inner cover 200. A foolproof notch 122 is formed between two adjacent first guard edges 121. Correspondingly, a foolproof protrusion 23 can be provided on the periphery of the inner cover 200. The foolproof protrusion 23 is embedded in the foolproof notch 122 to achieve the effect of mechanical foolproofing.

[0084] In some embodiments, a first adhesive groove is formed between the first retaining edge 121 and the first guide slope 22, and a portion of the fourth waterproof structure is accommodated in the first adhesive groove. The first cover 12 is also provided with a second retaining edge 123, and a second adhesive groove is formed between the second retaining edge 123, the first guide slope 22, and the adjacent ends of any two first retaining edges 121, and a portion of the fourth waterproof structure is accommodated in the first adhesive groove. The second adhesive groove communicates with the adjacent first adhesive groove, and the opening width of the second adhesive groove is greater than the opening width of the first adhesive groove. Furthermore, waterproof adhesive can be injected into the second adhesive groove, which has a larger space, and the waterproof adhesive injected from the second adhesive groove can flow into the first adhesive groove, thereby forming a complete fourth waterproof structure.

[0085] In some other embodiments, the anti-foolproof protrusion 23 can be engaged with the anti-foolproof notch 122, thereby achieving initial fixation of the inner cover 200 and the first cover 12 through the anti-foolproof protrusion 23 and the anti-foolproof notch 122, so as to prevent the waterproof adhesive from swelling and shifting the inner cover 200 during the process of injecting waterproof adhesive around the periphery of the inner cover 200 to form the fourth waterproof structure.

[0086] like Figure 2 As shown, to facilitate wiring of the drive assembly 700, the drive assembly 700 may be provided with a second electrical connector 71, such as TYPE-A, TYPE-C, MICRO-B, aviation connector, etc. The second electrical connector 71 is offset from the first electrical connector 31 in the height direction and / or width direction of the housing 100, and the second electrical connector 71 and the first electrical connector 31 are electrically connected by a wire (not shown in the figure).

[0087] Specifically, the second electrical connector 71 and the first electrical connector 31 may be offset only in the height direction of the housing 100; for example, the second electrical connector 71 and the first electrical connector 31 may be located at opposite ends of the first circuit board 300 in the height direction of the housing 100. Optionally, the second electrical connector 71 and the first electrical connector 31 may be offset only in the width direction of the housing 100; for example, the second electrical connector 71 and the first electrical connector 31 may be located at opposite ends of the first circuit board 300 in the width direction of the housing 100. Alternatively, the second electrical connector 71 and the first electrical connector 31 may be offset in both the height and width directions of the housing 100, which is not limited in this embodiment.

[0088] It is understandable that if the first electrical connector 31 and the second electrical connector 71 are directly plugged in, such as the first electrical connector 31 being a plug and the second electrical connector 71 being a socket that mates with the plug, the plug and socket may not mate accurately during the actual assembly process due to manufacturing errors and limitations such as the assembly method of the first cover 12.

[0089] In contrast, in this embodiment, a wire is added to connect the first electrical connector 31 and the second electrical connector 71. At the same time, the length of the wire is appropriately increased by the misalignment of the second electrical connector 71 and the first electrical connector 31, so that the wire can be deformed better. In the actual assembly process, the assembly difficulty caused by the manufacturing tolerance of the lock and the assembly method of the lock can be reduced by the adaptive deformation of the wire.

[0090] To limit the movement of the wires, the inner cover 200 may be provided with a wiring groove 29 on the side facing the inner shell 600. The wiring groove 29 is used to accommodate the wires, thereby making the wiring inside the lock neater and safer.

[0091] Specifically, the wiring trough 29 can be extended from the first electrical connector 31 toward the second electrical connector 71. The end of the wiring trough 29 near the first electrical connector 31 communicates with the second through hole 26. The third retaining edge 27 has a notch on the side near the wiring trough 29 so that the end of the first electrical connector 31 located outside the inner cover 200 can be directly plugged into the wire in the wiring trough 29.

[0092] In some embodiments, the inner shell 600 is provided with a fourth through hole 621, the second electrical connector 71 faces the fourth through hole 621, and the connector of the wire passes through the fourth through hole 621 and is electrically connected to the second electrical connector 71.

[0093] To improve the waterproof performance of the inner shell 600, the inner shell 600 may also include a fifth waterproof structure 622, which is used to seal the gap between the fourth through hole 621 and the wire.

[0094] Specifically, the fifth waterproof structure 622 may include a fifth sealing ring such as a fifth silicone seal or a fifth rubber seal, etc., but this application embodiment does not limit this.

[0095] Please continue to refer to Figure 5 and Figure 6 , Figure 5 for Figure 1 The top view of the lock shown. Figure 6 for Figure 5 The lock shown is a cross-sectional view along the AA direction. In some embodiments, the lock may also include an inner housing 600 and a transmission element 800.

[0096] The drive assembly 700 is disposed within the inner shell 600, thus providing dual protection for the drive assembly 700 through the outer shell 100 and the inner shell 600. The drive assembly 700 is electrically connected to the first circuit board 300, thereby charging and / or transmitting information through the coil of the first circuit board 300. A transmission member 800 passes through the inner shell 600 and is tractively connected to both the drive assembly 700 and the latch assembly 500, enabling the drive assembly 700 to drive the latch assembly 500 to release the locking component 41 via the transmission member 800. Other wireless devices can then charge the drive assembly 700 and send unlocking commands via the coil of the first circuit board 300, causing the drive assembly 700 to drive the latch assembly 500 to release the locking component 41, allowing the locking component 41 to move and unlock other items. Therefore, the lock of this embodiment can achieve a passive unlocking function.

[0097] Therefore, in the actual assembly process of the lock, the drive component 700 can be installed in the inner shell 600 first, and then the wires can be plugged into the first electrical connector 31 and the second electrical connector 71 respectively to realize the electrical connection between the first circuit board 300 and the second circuit board 72.

[0098] In some embodiments, the drive assembly 700 may include a second circuit board 72, an energy storage assembly 73, and a motor 74. Both the energy storage assembly 73 and the motor 74 are mounted on the second circuit board 72. The second circuit board 72 is electrically connected to a first electrical connector 31. For example, the second circuit board 72 may have the aforementioned second electrical connector 71 for electrical connection with the first electrical connector 31, so that energy and information received by the coils of the first circuit board 300 can be transmitted to the second circuit board 72 through the first electrical connector 31, and to charge the energy storage assembly 73, such as a capacitor or a battery. The energy storage assembly 73 supplies power to the motor 74, which is electrically connected to the transmission member 800, enabling the motor 74 to drive the transmission member 800.

[0099] For example, one end of the transmission member 800 located inside the inner housing 600 is connected to the output shaft of the motor 74 by means of a sleeve, engagement, or snap-fit, so that the motor 74 can drive the transmission member 800 to rotate.

[0100] In some embodiments, to improve the waterproof performance of the inner shell 600, the inner shell 600 is also provided with a fifth through hole 612, through which the transmission component 800 passes. Correspondingly, the inner shell 600 may be provided with a sixth waterproof structure 613, which blocks the gap between the fifth through hole 612 and the transmission component 800.

[0101] Specifically, the sixth waterproof structure 613 may include a sixth sealing ring, such as a sixth silicone sealing ring or a sixth rubber sealing ring, sleeved on the transmission component 800. This application embodiment does not limit this, so that while achieving sealing at the third through hole 24, the rotation of the transmission component 800 can be unrestricted.

[0102] Please continue to refer to this. Figures 7 to 9 , Figure 7 for Figure 1 The front view of the lock shown. Figure 8 for Figure 7 The lock shown is a cross-sectional view along the BB direction. Figure 9 for Figure 8 The diagram shows the structure of the transmission component of the lock. In some embodiments, in order to detect whether the drive assembly 700 drives the bolt assembly 500 to release the locking component 41, the drive assembly 700 may be provided with a first sensor 75, and a second circuit board 72 is electrically connected to the first circuit board 300 and the first sensor 75 respectively, so as to detect the movement state of the transmission component 800 or the movement position of the transmission component 800.

[0103] For example, the first sensor 75 may include a first limit switch. The first limit switch is located within the inner housing 600 to provide dual protection for the first limit switch through the outer housing 100 and the inner housing 600. Correspondingly, the outer periphery of the end of the transmission member 800 located within the inner housing 600 may be provided with a first protrusion 83 for following the rotation of the transmission member 800, such as forward rotation, to trigger the first limit switch.

[0104] To prevent incorrect rotation angle of the transmission component 800, a second protrusion 84 may be provided on the outer periphery of one end of the transmission component 800 located inside the inner shell 600. The second protrusion 84 is offset from the first protrusion 83 in the circumferential direction of the transmission component 800. Correspondingly, a first limiting part 623 and a second limiting part 611 are provided inside the inner shell 600. The first limiting part 623 and the second limiting part 611 are respectively located on both sides of the second protrusion 84 along the circumferential direction of the transmission component 800. Thus, the cooperation between the second protrusion 84 and the first limiting part 623 and the second limiting part 611 can limit the forward and reverse rotation angles of the transmission component 800.

[0105] For example, the second protrusion 84 is configured to cooperate with the first limiting part 623 to limit the maximum rotation angle when the transmission member 800 drives the locking tongue assembly 500 to release the locking member 41 or rotates forward, so as to prevent the first protrusion 83 from rotating beyond the maximum pressing stroke of the first limit switch, thereby avoiding damage to the first limit switch by the first protrusion 83.

[0106] The second protrusion 84 is configured to cooperate with the second limiting part 611 to limit the maximum rotation angle of the transmission member 800 when it is reset or reversed, thereby avoiding the first protrusion 83 from being in the wrong initial position in the locked state, which would cause the transmission member 800 to not drive the locking tongue assembly 500 to release the locking part 41 after the motor 74 drives the transmission member 800 to rotate forward.

[0107] In actual use, the transmission component 800 can be used only to drive the locking tongue assembly 500 to loosen the locking component 41, or it can be used simultaneously to drive the locking tongue assembly 500 to loosen or lock the locking component 41. This application embodiment does not limit this.

[0108] An eccentric cam 82 may be provided at one end of the transmission component 800 located outside the inner shell 600. The eccentric cam 82 is used to drive the locking tongue assembly 500 to move when it rotates. In turn, when the motor 74 drives the transmission component 800 to rotate, the eccentric cam 82 can drive the locking tongue assembly 500 to move.

[0109] In some embodiments, the transmission member 800 may be integrally formed with the first protrusion 83 and the eccentric cam 82 described above. Of course, the transmission member may also be integrally formed with the second protrusion 84 described above, and this application embodiment does not limit this.

[0110] In this design, the maximum outer diameter of the end of the transmission component 800 located outside the housing 100 is smaller than the outer diameter of the middle part of the transmission component 800, and the sixth waterproof structure 613 is fitted into the middle part of the transmission component 800. This facilitates the installation of the sixth sealing ring.

[0111] Continue to combine Figure 2 The latch assembly 500 may include a latch 51 and a first elastic member 52. The latch 51 is slidably mounted on the inner housing 600 or the outer housing 100 so that the latch 51 can slide to lock or release the locking member 41. The first elastic member 52 is mounted on the inner housing 600 or the outer housing 100 and drives the latch 51 to slide to lock the locking member 41.

[0112] For example, the inner shell 600 may include a second shell 61 and a second cover 62. The second shell 61 has a second cavity in which the drive assembly 700 is housed. A transmission member 800 passes through the second shell 61 for transmission connection with the drive assembly 700. The second cover 62 covers the second shell 61 to close the second cavity. Furthermore, the drive assembly 700 can be disassembled and assembled by removing and installing the second cover 62.

[0113] In some embodiments, to improve the waterproof performance of the inner shell 600, a ninth sealing ring 63 may be compressibly placed between the second shell 61 and the second cover 62. Specifically, the ninth sealing ring 63 may be a ninth rubber sealing ring or a ninth silicone sealing ring; this application embodiment does not limit this.

[0114] Please continue to refer to Figure 10 and Figure 11 , Figure 10 for Figure 1 The diagram shows the assembly of parts in the inner shell of the lock. Figure 11 for Figure 9 A schematic diagram of the second housing of the inner shell. Taking the example where the latch 51 and the first elastic member 52 are installed on the inner shell 600, one end of the second cover 62 may be provided with a mounting portion 625, located on one side of the second housing 61 along the height direction of the lock. The mounting portion 625 has a mounting groove. The latch 51 is slidably installed in the mounting groove, allowing it to slide along a first direction and a second direction, which are opposite. The first elastic member 52 is compressed between the inner wall of the mounting groove and the latch 51 to drive the sliding along the first direction. The eccentric cam 82 of the transmission member 800 can rotate with the transmission member 800 to push the latch 51 to rotate along the second direction.

[0115] One way the latch assembly 500 can release the locking component is as follows: the motor 74 drives the transmission component 800 to rotate 90° forward, and the eccentric cam 82 of the transmission component 800 pushes the latch 51 to move in the second direction until it separates from the locking component 41, so that the locking component 41 is released and the lock can be unlocked, and the first elastic member 52 is compressed.

[0116] One working principle of the locking tongue assembly 500 locking the locking component 41 is as follows: the motor 74 drives the transmission component 800 to reverse 90° to reset; at the same time, the first elastic element 52 elastically recovers to push the locking tongue 51 to move in the first direction, so that the locking tongue 51 can lock the locking component 41 again.

[0117] To detect the position of the locking component 41 to determine whether the lock is open or closed, the drive assembly 700 may include a second circuit board 72 and a second sensor 76. The second circuit board 72 is electrically connected to the first circuit board 300 and the second sensor 76, respectively. The inner shell 600 is provided with a ninth through hole 614 and an eighth waterproof structure 615 that closes the ninth through hole 614. The eighth waterproof structure 615 is made of a deformable material. The inner shell 600 is also provided with a trigger 64, which is located outside the inner shell 600. The locking component 41 can move relative to the outer shell 100 to drive the trigger 64 to move, so that the trigger 64 presses the eighth waterproof structure 615, thereby deforming the eighth waterproof structure 615 to trigger the second sensor 76.

[0118] Furthermore, the eighth waterproof structure 615 enables the lock to improve the waterproof performance of the inner shell 600 in addition to detecting the opening and closing of the locking component 41. At the same time, since the second sensor 76 is located inside the inner shell 600, the outer shell 100 and the inner shell 600 provide double protection for the second sensor 76.

[0119] In some implementations, the second sensor 76 may include at least one of a limit switch, a touch switch, and a micro switch.

[0120] In some embodiments, the eighth waterproof structure 615 may be made of an elastic material, so that after the pressing pressure applied by the trigger 64 is removed, the eighth waterproof structure 615 can elastically recover and reset. For example, the eighth waterproof structure 615 may include a silicone button or a rubber button.

[0121] For example, the ninth through hole 614 can be disposed in the second housing 61. The second housing 61 also has a second annular portion 616 surrounding the ninth through hole 614 and a fourth retaining edge 617 surrounding the second annular portion 616. The peripheral edge of the silicone button or rubber button is engaged between the second annular portion 616 and the fourth retaining edge 617. Furthermore, the silicone button or rubber button can form a more tortuous interface with the second annular portion 616 and the fourth retaining edge 617 to reduce the risk of water leakage, thereby further improving the waterproof performance at the ninth through hole 614. The second annular portion 616 and the fourth retaining edge 617 can also be regarded as reinforcing ribs to improve the strength of the second housing 61.

[0122] Of course, in some other embodiments, the second sensor 76 can automatically reset to drive the eighth waterproof structure 615 to recover after the pressing pressure applied by the trigger 64 is removed. This application embodiment does not limit this.

[0123] In some embodiments, the trigger 64 is rotatably mounted to the inner housing 600 at its center. The first end 641 of the trigger 64 abuts against the eighth waterproof structure 615, or the first end 641 of the trigger 64 is adjacent to the eighth waterproof structure 615. The second end 642 of the trigger 64 is movably engaged with the locking member 41, allowing the locking member 41 to move outwards from the housing 100 to push the second end 642, thereby causing the trigger 64 to rotate until the first end 641 presses against the eighth waterproof structure 615.

[0124] For example, the locking component 41 includes a first vertical portion 411 passing through the first through hole 111. One end of the first vertical portion 411 located inside the housing 100 may be provided with an annular groove 4111, and the second end 642 is accommodated in the annular groove 4111, so that when the second vertical portion 413 moves toward the outside of the housing 100, the groove wall of the annular groove 4111 can push against the movement of the second end 642, thereby causing the trigger 64 to rotate.

[0125] In some embodiments, the trigger 64 may be rotatably mounted on the second cover 62. For example, the second cover 62 may be provided with a mounting post 626, which passes through the middle of the trigger 64 to enable the rotatable mounting of the trigger 64. This application embodiment does not limit this.

[0126] To make the lock structure more compact, the mounting post 626 can be a hollow structure, and the inner shell 600 also includes a first fastener, such as a fastening screw, which passes through the mounting post 626. The fastener is detachably connected to the second shell 61.

[0127] The following explanation and description of the technical solution of the embodiments of this application will be further illustrated using a padlock as an example.

[0128] The locking component 41 may include a first vertical portion 411, a bent portion 412, and a second vertical portion 413 connected in sequence, such that the locking component 41 as a whole can be U-shaped. The first vertical portion 411 is movably inserted through the housing 100. A second elastic member 42 is provided inside the housing 100. The second elastic member 42 abuts against the first vertical portion 411 to drive the locking component 41 to move outward from the housing 100. The second vertical portion 413 is movably inserted through the housing 100, and a locking tongue 51 is inserted into the second vertical portion 413 to lock the locking component 41. The locking tongue 51 can also slide along a first direction to separate from the second vertical portion 413, thereby releasing the locking component 41.

[0129] It is understandable that if Figure 2 As shown, the locking member 41 can be U-shaped. As the first vertical portion 411 slides outward from the outer casing 100, the other end of the locking member 41 can separate from the outer casing 100, thus unlocking the lock. Conversely, as the first vertical portion 411 slides inward from the outer casing 100, the other end of the locking member 41 can insert into or abut against the outer casing 100, thus locking the lock. Alternatively, the first vertical portion 411 can be a cylindrical shaft, allowing the locking member 41 to rotate around its axis when the lock is unlocked.

[0130] Please continue to refer to this. Figure 12 , Figure 12 for Figure 6 The image shows a partial enlarged view after the first sealing ring is installed at point X. In some embodiments, a first annular wall 112 protrudes from the outer surface of the housing 100, forming the aforementioned first through hole 111. A first vertical portion 411 passes through the first through hole 111. The first vertical portion 411 is provided with a seventh waterproof structure 44, such as a waterproof sleeve, to seal the gap between the first vertical portion 411 and the first through hole 111.

[0131] Specifically, the seventh waterproof structure 44 includes a first annular portion 441 surrounding the first vertical portion 411 and a second annular wall 442 surrounding the first annular portion 441. The second annular wall 442 is sleeved on the outer periphery of the first annular wall 112 and is in clearance fit with the first annular wall 112 to form a sliding connection.

[0132] The first sealing ring 43 can be sleeved on the first vertical part 411, and the first sealing ring 43 is at least partially compressed and placed between the end face of the opening of the first through hole 111 and the first annular part 441, so as to improve the sealing effect between the seventh waterproof structure 44 and the first annular wall 112.

[0133] In some embodiments, the first sealing ring 43 can be made of an elastic material such as rubber or silicone. Therefore, when the locking tongue 51 is separated from the second vertical part 413, the first sealing ring 43 can undergo elastic deformation to push the first annular part 441, thereby realizing that the locking component 41 automatically pops out of the outer shell 100.

[0134] For example, the first sealing ring 43 can be partially compressed and disposed between the orifice end face of the first through hole 111 and the first annular portion 441, so that a first double seal is formed between the orifice end face of the first through hole 111 and the first annular portion 441. Furthermore, the first sealing ring 43 can be partially compressed and disposed between the hole wall of the first through hole 111 and the first vertical portion 411, so that a second double seal is formed between the hole wall of the first through hole 111 and the first vertical portion 411.

[0135] Therefore, combined with the waterproof protection provided by the inner shell 600 to the drive assembly 700, the lock of this embodiment provides at least triple waterproof protection for the drive assembly 700 and other components within the inner shell 600. Furthermore, combined with the waterproof structure of the inner cover 200 to the first circuit board 300, the lock of this embodiment provides at least triple waterproof protection for the first circuit board 300 and other components within the inner cover 200.

[0136] In some embodiments, the housing 100 is further provided with an eighth through hole 113 through which the second vertical portion 413 passes. The second vertical portion 413 may be fitted with an eighth sealing ring 414, which abuts against the wall of the eighth through hole 113 to seal the gap between the wall of the eighth through hole 113 and the second vertical portion 413.
