[0032] The present application provides a lock structure 100.
[0033] Please refer to Figure 1 In an embodiment, the lock structure 100 includes a signal contact sheet 1 and a lock beam 2. The signal contact sheet 1 includes two clamping sheet bodies 11, which are oppositely and spacedly arranged, and a clamping space is formed between the two clamping sheet bodies 11. The lock beam 2 is provided with a sensing head 21 at one end, and the sensing head 21 can be extended into or withdrawn from the clamping space to have a locking state and an unlocking state. In the locking state, the sensing head 21 is in abutting contact with the two clamping sheet bodies 11. In the unlocking state, the sensing head 21 is staggered with the two clamping sheet bodies 11.
[0034] The lock structure 100 provided by the utility model has two clamping pieces 11, the induction head 21 can extend into or exit the clamping space formed by the two clamping pieces, and the induction head 21 is in full contact with the clamping piece 11 in the locked state and is staggered in the unlocked state. On the one hand, the design of the two clamping pieces 11 enables the induction head 21 to have multiple contact states in the clamping space, and compared with a single contact point, the multi-point contact mode can more reliably transmit the switch state signal of the lock, reduces signal transmission failure caused by poor contact, on the other hand, the design of the two clamping pieces 11 increases the contact area and disperses the contact pressure, thereby reducing wear or deformation caused by excessive local pressure, so that the lock structure 100 can better fix the induction head 21 in the locked state to lock the lock beam 2 in the lock body 3, and the structure can maintain stable contact when subjected to vibration, reduces poor contact or disconnection caused by vibration, can provide more reliable signal contact in applications that need to be frequently locked and unlocked, improves the service life of the lock, and ensures normal operation of the lock for a long time.
[0035] In an embodiment, part of the structure of the clamping piece 11 is arranged close to the other clamping piece 11, and the induction head 21 is in abutting contact with the part of the two clamping pieces 11 close to each other. The part of the structure of the clamping piece 11 close to the other clamping piece 11 forms a more compact and stable contact area. This design can ensure that the induction head 21 effectively contacts the clamping piece 11 in a smaller space, so that the contact area of the induction head 21 and the clamping piece 11 relatively increases, which helps to improve the stability of the contact and the reliability of the signal transmission. In addition, the close design of the clamping piece 11 makes the overall structure more compact, which is beneficial to reducing the volume of the lock and is suitable for application occasions with limited space. It should be noted that "the part of the structure of the clamping piece 11 close to the other clamping piece 11" can be that one side of the clamping piece 11 close to the other clamping piece 11 is provided with a protrusion, or the clamping piece 11 itself has a bending position to form a certain angle, so that the bending part can be close to the other clamping piece 11. The bending can be fixed bending or dynamic bending realized by elastic material. The latter can change shape when subjected to external force, thereby realizing contact with the other clamping piece 11. The advantage of this structure is that the clamping piece 11 can be close in a smaller space, which is suitable for compact design.
[0036] In an embodiment, the side of the clamping piece 11 close to the other clamping piece 11 is arc-shaped. The arc-shaped surface can make the clamping force more evenly distributed to the clamped induction head 21, reducing local pressure concentration, thereby reducing potential damage to the object, and the arc-shaped surface has a certain self-alignment capability, that is, even if there is a slight deviation in the manufacturing or assembly process, the arc-shaped surface can automatically adjust the position to a certain extent and achieve good docking with the arc-shaped surface of the other clamping piece 11. In addition, the arc-shaped surface can make the lock beam 2 more smooth during insertion into the clamping space, providing a better hand feel and operation experience. In this case, the material of the clamping piece 11 needs to have a certain elasticity and wear resistance to adapt to the characteristics of the arc-shaped surface.
[0037] In an embodiment, the side of the clamping piece 11 away from the arc-shaped surface is provided with a clamping through hole 111 penetrating to the arc-shaped surface; in the locked state, part of the structure of the induction head 21 penetrates into the clamping through hole 111. This mechanical connection method can prevent the induction head 21 from accidentally falling off or moving, ensuring that the lock remains in the locked state, and the cooperation design of the clamping through hole 111 and the induction head 21 enables the clamping piece 11 to maintain a compact structure while providing effective locking function. In addition, in the above structure, in order to ensure that the induction head 21 can smoothly extend into and exit the clamping space, a guide surface is usually provided on the induction head 21, which can contact the clamping piece 11 during locking and unlocking and help part of the structure of the induction head 21 to smoothly penetrate into the clamping through hole 111, reducing friction and damage caused by misalignment. Preferably, the guide surface is usually tapered or inclined to facilitate insertion and exit.
[0038] In an embodiment, the clamping piece 11 is recessed towards the clamping section close to the other clamping piece 11 in the direction from both ends to the middle, so as to abut against the induction head 21. During the insertion or extraction of the induction head 21, the recessed part may be slightly elastically deformed, which helps to absorb the impact force and reduce damage to the induction head 21. When the induction head 21 is inserted, the higher part of both ends first contacts the induction head 21, and as the insertion is further inserted, the recessed part in the middle gradually fits the induction head 21. After the induction head 21 is completely inserted, the recessed part can cooperate with the specific structure (such as protrusions, grooves, etc.) of the induction head 21 to achieve the locking effect. When the induction head 21 needs to be extracted, the recessed part can also provide guidance, so that the induction head 21 can smoothly exit.
[0039] In an embodiment, the signal contact further comprises a mounting piece 12, and the two clamping pieces 11 are oppositely and spacedly arranged on both sides of the mounting piece 12. The mounting piece 12 is a component part of the signal contact structure, which is used to fix and support the clamping piece 11 and provides a stable mounting basis for the clamping piece 11.
[0040] In one embodiment, the mounting plate 12 defines a mounting hole 121. The lock structure 100 further includes a locking member, the locking end of which passes through the mounting hole 121 to secure the mounting plate 12 within the lock body 3. The locking member may create friction or a clamping effect with the inner wall or other structures of the lock body 3, thereby ensuring that the mounting plate 12 does not shift during use. During lock assembly, the mounting plate 12 is first placed in a predetermined position within the lock. Subsequently, the locking end of the locking member passes through the mounting hole 121 of the mounting plate 12 and is securely secured within the lock body 3 by rotation, pressing, or other manipulation. This securing method ensures that the signal contact plate 1 remains stable within the lock, preventing it from falling off or being damaged by external forces or vibration. It also simplifies the installation and removal process, facilitates maintenance and component replacement, and improves the overall reliability and service life of the lock.
[0041] In one embodiment, the mounting plate 12 is provided with a plurality of mounting holes 121 at intervals. The lock structure 100 includes a plurality of locking members, each corresponding to each of the plurality of mounting holes 121. The plurality of mounting holes 121 at intervals on the mounting plate 12 means that the mounting plate 12 has multiple fixing points, rather than a single fixing point. This design increases the stability of the mounting plate 12, preventing it from twisting or deforming when subjected to external forces. It also enhances the stability of the mounting plate 12 and improves the assembly accuracy of the lock.
[0042] In one embodiment, the mounting plate 12 and the two clamping plates 11 are an integrally formed structure. An integrally formed structure is generally stronger than an assembled structure because there are no seams or connection points and it can better withstand external forces and vibrations. In addition, the integral forming can ensure higher manufacturing precision and reduce the number of assembly steps, thereby reducing manufacturing costs and improving production efficiency.

Since the smart padlock 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
