Description

Technical Field

[0001] This invention relates to the field of locking device technology, and more specifically, to a locking device. Background Technology

[0002] Currently, common locking devices typically integrate the release mechanism with the locking mechanism in the same or adjacent location. For example, a typical push-button lock has the button directly located on the movement path of the latch or locking block, requiring the user to operate it directly from the locked position. While this integrated design is relatively simple, it has significant limitations in practical applications: First, the release operation position is fixed at the locking point, making it impossible to flexibly arrange it in a more convenient or concealed location based on the ergonomic, aesthetic, or functional requirements of the usage scenario; second, when a single operation point needs to simultaneously control multiple discretely distributed locking points (e.g., on large boxes, protective clothing, or backpacks with multiple fixed points), traditional structures often require a separate operating component for each locking point, resulting in complex structure, increased cost, and cumbersome operation.

[0003] To improve ease of operation, some existing technologies employ remote unlocking solutions using methods such as pull cables and linkages. However, these solutions still have several shortcomings: First, the design of the transmission mechanism is often complex, with fixed arrangement paths for the pull cables or linkages, resulting in poor versatility and adaptability, making it difficult to flexibly adapt to the needs of a single operating point simultaneously controlling multiple discretely distributed locking points or different spatial layouts; second, the alignment and locking process of the male and female latches often relies on precise mechanical alignment by the user, leading to a poor user experience, especially in scenarios with poor visibility or single-handed operation; third, the force transmission efficiency, direct response, and structural reliability during the transmission process still need improvement. For example, the pull cable may become loose or jammed, affecting the unlocking feel and reliability.

[0004] Therefore, it is necessary to improve the existing locking device and design a locking device that allows the release operation component and the locking component to be arranged separately, can flexibly adapt to single-point or multi-point locking control, has magnetic assisted docking function, and has reliable and direct transmission, so as to meet the increasingly diverse application scenarios. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a locking device that solves the technical problems of existing technologies, such as the inability to control multiple discretely distributed locking points simultaneously through single-point operation and the complexity of the structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a locking device, comprising:

[0008] The female buckle includes a release operation component and a locking component for setting in different location scenarios, wherein the release operation component and the locking component are connected by a pull wire;

[0009] The male buckle is a lockable connection that can be locked and can be released from the locking assembly;

[0010] When the release mechanism is operated, the release mechanism is linked to the pull cable to cause the locking component to disengage from the male buckle.

[0011] Furthermore, the release operation component is provided with a first mounting part, and the first mounting part is provided with a first mounting hole;

[0012] The pull cord can be selectively disposed within the first mounting hole or wound around the first mounting portion and can move with the release operation component to selectively provide one or more pull cord paths to connect with one or more of the locking components.

[0013] Furthermore, the pull cable includes a conduit and a core wire sleeved inside the conduit. The conduit is used to fix the position of the core wire, and the core wire can slide inside the conduit. One end of the conduit is fixedly mounted on the release operation component, and the other end is fixedly mounted on the locking component, so as to ensure that the pull cable directly responds to the tension between the release operation component and the locking component.

[0014] Furthermore, the release operation component includes a first fixing member and a release key;

[0015] The release key is limited to the first fixing member and can move relative to the first fixing member;

[0016] The first mounting part is located on the release key.

[0017] Furthermore, the first fixing member is provided with a first lead wire groove, which extends along the moving direction of the release key. The first lead wire groove is used to guide the pull wire portion connected to the first mounting part along the moving direction of the release key.

[0018] Furthermore, the first fixing member is provided with three first lead wire grooves to selectively adapt one pull wire to link one locking component, one pull wire to link two locking components, or two pull wires to link three locking components.

[0019] Furthermore, an elastic element is provided between the first fixing member and the release key to drive the release key to move and then reset.

[0020] Furthermore, the locking assembly is provided with a first magnet, and the male buckle is provided with a second magnet;

[0021] The first magnet is magnetically attracted to the second magnet along the engagement direction and can be separated, so that the male buckle and the locking assembly are magnetically attracted to each other along the engagement direction and can be separated.

[0022] Furthermore, the male buckle is provided with a locking groove, and the locking assembly is provided with a locking part corresponding to the locking groove; when the male buckle and the locking assembly are engaged in the engagement direction, the locking part is engaged in the locking groove, so that the male buckle cannot disengage from the locking assembly in the opposite direction to the engagement direction.

[0023] Furthermore, the locking assembly includes a second fixing member and a moving member;

[0024] The second fastener has a lock hole, the male buckle has a lock tongue that can be correspondingly inserted into the lock hole, and the lock tongue has a locking groove;

[0025] The first magnet is provided at the bottom of the keyhole, and the second magnet is provided inside the lock tongue;

[0026] The movable component is limited and can move relative to the second fixed component. The movable component is provided with the locking part and is connected to the pull wire.

[0027] When the male buckle engages with the locking assembly along the engagement direction, the first magnet and the second magnet are magnetically attracted, the latch is inserted into the lock hole, and the locking part engages with the locking groove; when the pull cord is pulled, the moving member moves in a direction perpendicular to the engagement direction, causing the locking part to disengage from the locking groove, so that the male buckle can disengage from the locking assembly in the opposite direction to the engagement direction.

[0028] Furthermore, the movable part has a second mounting portion on the side opposite to the lock hole, and the second mounting portion has a second mounting hole;

[0029] The pull wire is disposed in the second mounting hole and connected to the movable component.

[0030] Furthermore, a third magnet is fixedly provided on the moving part;

[0031] When the latch is inserted into the lock hole, the second magnet and the third magnet interact to drive the moving member to move until the locking part engages with the locking groove.

[0032] Furthermore, the second fixing member has a sliding groove on the side opposite to the lock hole for the second mounting part to be inserted. The sliding groove extends along the moving direction of the moving member, and the second mounting part can move within the sliding groove.

[0033] Furthermore, the second fixing member has a second lead wire groove on the side opposite to the lock hole, which is arranged along the moving direction of the moving member; the second lead wire groove is used to guide the pull wire portion connected to the second mounting part along the moving direction of the moving member.

[0034] Furthermore, the movable component includes an annular arm that surrounds the outside of the keyhole and is movable relative to the keyhole. The annular arm has a locking portion on the side facing the keyhole, a second mounting portion on the side facing away from the keyhole, and the third magnet on the annular arm.

[0035] When the bolt is inserted into the keyhole, the second magnet and the third magnet interact to drive the annular arm to move until the locking part engages with the locking groove.

[0036] When the annular arm moves with the second mounting part under the linkage of the pull line, the locking part disengages from the locking groove, so that the male buckle can disengage from the locking assembly in the opposite direction to the engagement direction.

[0037] Furthermore, the moving component includes a linkage block and a rotating arm rotatably mounted on the second fixed component;

[0038] The linkage block is connected to the non-rotation center of the rotating arm;

[0039] The linkage block has a second mounting part on the side away from the lock hole, the rotating arm has a locking part on the side facing the lock hole, and the rotating arm has a third magnet.

[0040] When the bolt is inserted into the lock hole, the second magnet and the third magnet interact to drive the rotating arm to rotate until the locking part engages with the locking groove.

[0041] When the linkage block moves along with the second mounting part under the linkage of the pull line, the linkage block drives the rotating arm to rotate so that the locking part disengages from the locking groove and the male buckle can disengage from the locking assembly in the opposite direction to the engagement direction.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. By designing the release mechanism and the locking mechanism as two independent modules connected by a pull cable, the limitation of traditional locking mechanisms, which require the locking point to be fixed near the engagement point, is fundamentally broken. Users can place the release mechanism in a more accessible, user-friendly, or aesthetically pleasing location (such as the side of the case, backpack straps, or the hem of clothing) based on the overall product design, ergonomic requirements, or application scenarios. The locking mechanism can be placed in the functional area requiring connection and fixation, greatly enhancing the freedom of product design and user experience.

[0044] 2. The release operation component has a first mounting part and a first mounting hole therein. The pull cable can be selectively located in the first mounting hole or wound around the first mounting part to provide one or more pull cable paths to connect with one or more locking components. Through simple wiring, a single release operation component can simultaneously control one, two, or more spatially discrete locking components. This effectively solves the problem of needing multiple independent operating parts in multi-point fixing scenarios, significantly simplifies the overall structure, reduces manufacturing costs, and allows users to release all locking points with a single operation, greatly improving ease of use. It is particularly suitable for applications requiring quick on / off or multi-point locking, such as bags, protective equipment, and child safety seats.

[0045] 3. The pull cable employs a combination structure of a conduit and an internal sliding core wire, with both ends of the conduit fixed to the release operation component and the locking component, respectively. This design ensures that the operating force is transmitted directly and without loss through the core wire within a fixed path, avoiding the force transmission delays or jamming problems that may occur with traditional flexible pull cables due to slack or bending. Simultaneously, the lead grooves on the release operation component and the locking component effectively guide and limit the pull cable, further ensuring the stability and reliability of the transmission path and providing users with a clear and consistent release feel.

[0046] 4. A first magnet and a second magnet are respectively installed in the locking assembly and the male buckle. Magnetic attraction guides the male buckle's bolt to initially align and attract the female buckle's lock hole, greatly reducing the accuracy requirements for alignment. This is particularly suitable for scenarios with poor visibility or one-handed operation, improving the convenience and success rate of locking operations. Furthermore, by installing a third magnet on the moving part of the locking assembly, which interacts with the second magnet in the male buckle, the moving part automatically moves to the locking position after the bolt is inserted into the lock hole, achieving an automatic "insert and lock" locking function. This simplifies user operation and enhances the reliability and consistency of the locking state. Attached Figure Description

Detailed Implementation

[0061] The invention will now be further described with reference to the accompanying drawings.

[0062] refer to Figure 1 and Figure 2 As shown, an embodiment of the present invention is a locking device, which includes a female buckle 10 and a male buckle 20 that can engage with and detach from the female buckle 10.

[0063] The female buckle 10 includes a release operation component 11 and a locking component 12 for use in different locations. The release operation component 11 and the locking component 12 are connected by a pull wire 13. The male buckle 20 is correspondingly lockable and lockable to the locking component 12. When the release operation component 11 is operated, the release operation component 11, in conjunction with the pull wire 13, causes the locking component 12 to disengage from the male buckle 20.

[0064] Specifically, the female buckle 10 is used to fix it on an object (such as a box, backpack body, clothing, etc.) that needs to be connected. It consists of a release operation component 11 and at least one locking component 12 that can be spatially distributed or separated.

[0065] The release mechanism 11 is an interactive component for users to directly perform the release operation. Its core function is to receive user input (such as pressing, sliding, or flicking) and convert this input into mechanical drive for the transmission mechanism. It can be independently placed in appropriate locations based on ergonomics, aesthetics, functional requirements, or application scenarios, such as the side of a case, near the shoulder strap of a backpack, or the hem of clothing. It no longer needs to be confined to the locking point card lock component 12 and can be flexibly installed in different required locations and scenarios.

[0066] The locking component 12 is the mechanism that actually performs the locking and unlocking function with the male buckle 20, and it is located at the position where it needs to be locked with the male buckle 20.

[0067] The release operation component 11 and the locking component 12 are physically connected by one or more pull wires 13, thereby enabling remote force transmission and control. As a flexible transmission link connecting the release operation component 11 and the locking component 12, it reliably transmits the force and movement applied by the user on the release operation component 11 to the locking component 12, which may be located in different scenarios, thereby driving its action.

[0068] The male buckle 20 is used to fix and install on another object (such as a box lid, backpack lid, another part of clothing, etc.) that needs to be connected to the female buckle 10, and its structure matches the locking assembly 12. The male buckle 20 can approach and lock with the locking assembly 12 along a predetermined engagement direction (usually a direction perpendicular to the mounting surface), and can also be released and separated in the opposite direction of engagement.

[0069] When the user needs to unlock, an operation (such as pressing, sliding, or flicking) activates the movable part inside the unlocking mechanism 11. This operation directly triggers the pull cable 13 connected to it, applying a pulling force to the cable 13. This pulling force is transmitted through the pull cable 13 and remotely acts on the locking mechanism 12, causing the locking mechanism 12 to perform an unlocking action, thereby disengaging it from the male latch 20. At this point, the male latch 20 can be operated to separate from the locking mechanism 12 without obstruction, thus opening the two connected objects.

[0070] This application fundamentally breaks the limitation that the traditional locking operation point must be fixed near the locking point, achieving complete separation between the operation position and the locking position, greatly improving the convenience of use and the flexibility of product design. Users can place the release operation component 11 in a more accessible, more user-friendly, or more aesthetically pleasing and concealed location (such as the side of the case, backpack shoulder strap, or hem of clothing) according to the overall product design, ergonomic requirements, or application scenarios, while placing the locking component 12 in the functional parts that need to be connected and fixed, greatly improving the freedom of product design and user experience.

[0071] Furthermore, in some embodiments, such as Figure 2 As shown, to allow for more flexible arrangement of the pull cable 13 and to adapt to control one or more locking assemblies 12, the release operation assembly 11 is provided with a first mounting part 111, and the first mounting part 111 is provided with a first mounting hole 1111. The pull cable 13 can be selectively disposed in the first mounting hole 1111 or wound around the first mounting part 111 and can move with the release operation assembly 11 to selectively provide one or more pull cable paths to connect with one or more locking assemblies 12.

[0072] The first mounting part 111 is specifically used for connecting the pull wire 13. The first mounting part 111 can be a boss, an annular flange, a column, or a protruding structure with a specific shape. A first mounting hole 1111 is provided on the first mounting part 1111, which can be a through hole or a groove.

[0073] Preferably, the first mounting part 111 is constructed as an annular protrusion, the annular protrusion surrounds the first mounting hole 1111 can be directly formed in the middle, and a notch for the pull wire 13 to pass through is provided on the surrounding annular protrusion, so that the end of the pull wire 13 can be fixedly installed in the first mounting hole 1111 after passing through.

[0074] The connection method between the pull wire 13 and the first mounting part 111 is highly flexible to adapt to different wiring requirements. Specifically, the connection methods include: directly inserting the end of the pull wire 13 (e.g., by knotting, riveting, or using clips, usually with a plug larger than the hole diameter) into the first mounting hole 1111 and fixing it. This method provides a strong connection and is suitable for single-path heavy-duty transmission; or wrapping the middle section of the pull wire 13 (e.g., wrapping it one or more times) around the column of the first mounting part 111 so that the pull wire 13 can move with the first mounting part 111, allowing at least two locking assemblies 12 to be connected at both ends of the pull wire 13. Of course, pull wires can also be installed simultaneously in the first mounting hole 1111 and on the first mounting part 111, forming three pull wire paths to connect three locking assemblies 12.

[0075] This flexible connection method allows designers to selectively provide one or more pull wire paths based on the number and layout of the locking components 12 in the actual product. For example, one end of a single pull wire 13 can be fixed to the first mounting part 111, and the other end can be connected to a locking component 12, forming a one-to-one control path. Alternatively, multiple strands can be split off from the first mounting part 111 using a splitter or directly, allowing a single pull wire 13 to connect to two or more locking components 12, forming a one-to-many control path. Even multiple independent pull wires 13 can be used, each with one end connected to the same first mounting part 111 in the same or different ways (fixed in a hole or wound around), and the other end connected to different locking components 12, achieving precise control of multiple locking points from a single operating point.

[0076] Furthermore, in some embodiments, such as Figure 4 As shown, to ensure the directness, efficiency, and clear feel of the long-range force transmission, the pull cord 13 is constructed as an outer conduit 131 and a core wire 132 that is sleeved inside the conduit 131 and can slide freely. The conduit 131 is fixed in position, while the core wire 132 can slide within the conduit 131. In practical applications, the conduit 131 is fixed in the usage scenario, for example, fixed in a compartment of a suitcase. One end of the conduit 131 is fixedly mounted on the release operation component 11, and the other end is fixedly mounted on the locking component 12, to ensure that the pull cord 13 directly responds to the pulling force between the release operation component 11 and the locking component 12.

[0077] The conduit 131 is made of a flexible material with certain resistance to compression and bending deformation (such as plastic or braided flexible tubing). Its main function is to provide a fixed, protected, low-friction, and geometrically stable channel for the internal core wire 132. The conduit 131 itself does not transmit tensile force, but the fixing at both ends ensures that the sliding path of the internal core wire 132 is strictly defined. The core wire 132 is made of a high-strength, low-elongation material (such as steel wire or polymer fiber thread) and is used to transmit tensile force; it is the true medium for tensile force transmission.

[0078] During installation, both ends of the conduit 131 are fixed in position. Specifically, one end of the conduit 131 (the end closer to the release operation assembly 11) is securely fixed to the release operation assembly 11 by means of clips, adhesive, or structural limiting. The other end of the conduit 131 (the end closer to the locking assembly 12) is also securely fixed to the locking assembly 12 in a similar manner. The middle part of the conduit 131 can be fixed to the place of use in various ways. In this way, the conduit path between the release operation assembly 11 and the locking assembly 12 is determined.

[0079] The core wire 132 passes through the entire conduit 131, and its two ends are respectively connected to the moving parts of the release operation assembly 11 (such as the release key 113) and the moving parts of the locking assembly 12.

[0080] When the user operates the release mechanism 11, they directly pull the core wire 132. Since both ends of the conduit 131 are fixed, the movement of the core wire 132 cannot be absorbed by compressing or bending the conduit. The pulling force is immediately and without delay applied to the moving part of the remote locking assembly 12, achieving a direct pull response. This solves the problems of elastic elongation and frictional lag caused by pulling the entire rope, providing a direct and rapid unlocking feel. Furthermore, the conduit 131 simultaneously protects the core wire 132 from external wear and contamination, and prevents it from tangling with other components in complex paths.

[0081] In some embodiments, such as Figure 2 and Figure 3 As shown, the release operation assembly 11 includes a first fixing member 112 and a release key 113. The release key 113 is limitedly connected to the first fixing member 112 and can move relative to the first fixing member 112, and a first mounting part 111 is provided on the release key 113.

[0082] The first fixing member 112 constitutes the main frame and mounting base of the release operation assembly 11, and is usually fixed to the product body by means of screws, clips, or adhesive. It is usually made of rigid plastic or metal and is the stationary part of the entire assembly. Of course, a groove can also be directly opened in the product body to form the first fixing member 112. As long as the release button 113 can be slidably installed, the function and structure are the same here.

[0083] The release button 113 is a movable part that is directly operated by the user. As a movable part that is directly operated by the user, its material needs to balance strength and tactile feel. The release button 113 is connected to the first fixing member 112 through a specific structure (such as the cooperation of the slide and the slider, the cooperation of the guide post and the guide hole, and the peripheral limiting type), so that the release button 113 can only reciprocate or slide relative to the first fixing member 112 in a specific predetermined direction, and will not disengage or undergo other unexpected movements.

[0084] The first mounting part 111 is positioned directly on the release button 113. This means that when the user pushes or pulls the release button 113, the first mounting part 111 moves synchronously, thereby directly applying tension to the connected pull wire core 132. This design converts the user's operating force into transmission tension most directly, achieving the highest efficiency.

[0085] Furthermore, in some embodiments, such as Figure 2 and Figure 3 As shown, in order to ensure that the pull wire 13 (especially the core wire 132 segment) leading out from the moving release key 113 has a smooth path during movement and to avoid wear, jamming or loss of tension due to random bending, the first fixing member 112 is provided with a first lead wire groove 1121. The first lead wire groove 1121 extends along the moving direction of the release key 113. The first lead wire groove 1121 is used to guide the pull wire 13 portion connected to the first mounting part 111 along the moving direction of the release key 113, ensuring that the operating force can be transmitted more effectively and that the user feels a smooth force.

[0086] Specifically, the first lead groove 1121 is a recess, channel, or extended wall groove, and its extension direction is designed to be consistent with the movement direction of the release key 113. After the pull wire 13 is led out from the first mounting part 111, its section near the release operation component 11 (that is, the end of the conduit 131 near the release operation component 11) is accommodated and guided in the first lead groove 1121. In this way, regardless of whether the release key 113 is in the initial position or the displacement position after being operated, this section of the pull wire 13 can be constrained by the first lead groove 1121 to a straight line or a smooth path parallel to the direction of movement, avoiding the pull wire 13 from swinging, scraping, or excessively bending due to the movement of the release key 113, ensuring smooth force transmission and the durability of the component.

[0087] In some embodiments, such as Figure 3As shown, to ensure the versatility and configuration flexibility of the release operation component 11, the first fixing member 112 is provided with three first lead wire slots 1121 to selectively accommodate one pull wire 13 linking one locking component 12, one pull wire 13 linking two locking components 12, or two pull wires 13 linking three locking components 12. Of course, this is not a limitation; the number of first lead wire slots 1121 can be set to a greater number, depending on the actual number of locking components 12 to be controlled. This design allows the same release operation component hardware platform to cover a variety of product requirements, from simple to complex, reducing mold development and inventory costs, and greatly enhancing the versatility and adaptability of the release operation component 11 to different product layouts.

[0088] Furthermore, in some embodiments, such as Figure 2 and Figure 3 As shown, in order to achieve automatic reset of the release key 113, ensure that the component is immediately ready for the next locking after each unlocking operation, and provide clear operation feedback to the user, an elastic element 114 is provided between the first fixing member 112 and the release key 113. The elastic element 114 is preferably a compression spring, a torsion spring, or an elastic rubber block.

[0089] Specifically, the two ends of the elastic element 114 abut against the first fixing element 112 and the release button 113, respectively. Its installed state allows the elastic element 114 to store a certain amount of elastic potential energy. When the user operates the release button 113 to move against the elastic force (complete unlocking), the elastic element 114 is further compressed or twisted. Once the user releases the operating force, the elastic potential energy stored in the elastic element 114 is released, and its rebound force drives the release button 113 to move in the opposite direction until it returns to its initial position. This provides clear operational feedback to the user and ensures that the device is ready to lock again after each unlock, making it convenient for the user.

[0090] In some embodiments, such as Figure 2 and Figure 3 As shown, in order to achieve a stable installation and precise guidance of the release key 113, the first fixing member 112 is provided with a receiving cavity 1122, and the release key 113 is limited and disposed in the receiving cavity 1122 and can move relative to the receiving cavity 1122.

[0091] The receiving cavity 1122 is a cavity formed inside the first fixing member 112 or formed by two parts fitting together. Its shape matches the shape of the release key 113 and is slightly larger, providing precise receiving space and movement clearance for the release key 113.

[0092] The release key 113 is placed entirely or partially within the receiving cavity 1122. The cavity wall of the receiving cavity 1122 restrains the movement of the release key 113 through physical contact. Specifically, the restraint method can be: a sliding fit is formed between the edge of the release key 113 and the cavity wall of the receiving cavity 1122; or, mutually engaging guide rails and grooves are provided on the release key 113 and the wall of the receiving cavity 1122. With this structure, the release key 113 is constrained to move only within the receiving cavity 1122 in a designed direction relative to the receiving cavity 1122 (i.e., relative to the first fixing member 112). The overall structure is compact and stable, with strong resistance to impact and misoperation.

[0093] Furthermore, in some embodiments, such as Figure 3 As shown, in order to allow users to operate the release key 113 contained in the accommodating cavity 1122 from the outside, the accommodating cavity 1122 is provided with an operation window 1123, which exposes part of the release key 113 so that the release key 113 can be operated from the operation window 1123.

[0094] Specifically, an operation window 1123 is provided on the wall of the accommodating cavity 1122 (typically the outer surface of the first fixing member 112 facing the user). This operation window 1123 is an opening whose size and position allow a portion of the body of the release key 113 to be exposed through the window. The user can use this operation window 1123 to touch the exposed portion of the release key 113 with their fingers or tools and apply operating force to it, thereby moving the release key 113.

[0095] Furthermore, in some embodiments, such as Figure 3 and Figure 5 As shown, in order to further facilitate user operation, the release key 113 is recessed in the exposed part of the operation window 1123 in the direction away from the operation window 1123 to form a latching groove 1131, which is used to insert a finger into the latching groove 1131 to operate the release key 113.

[0096] The portion of the release button 113 exposed in the operation window 1123 is not flat; instead, it is recessed away from the operation window 1123, forming a groove 1131. The shape of this groove 1131 typically fits the fingertip or fingertip. When the user needs to operate it, the fingertip can be inserted into this groove 1131. The recessed groove 1131 provides good accommodation and support for the fingertip, offering an excellent point of leverage, preventing slippage when the user pulls or presses the release button 113, enabling blind operation and making operation more effortless and precise.

[0097] Furthermore, in some embodiments, such as Figure 5As shown, in order to provide a locking groove 1131 while also guiding and limiting the movement of the release key 113, the groove edge of the locking groove 1131 protrudes in the direction of the operation window 1123 to form a limiting edge 1132. The limiting edge 1132 is embedded in the operation window 112 to guide the movement of the release key 113.

[0098] Specifically, a protruding limiting edge 1132 is formed at the edge of the groove 1131 (i.e., the groove edge) towards the operation window 1123. In the assembled state, this protruding limiting edge 1132 can be precisely inserted into the inner side of the opening edge of the operation window 1123.

[0099] This design achieves a dual function: the limiting edge 1132 is embedded in the operation window 1123, which is equivalent to adding a guide surface in the moving direction of the release key 113. In conjunction with the edge of the window, it can guide the movement of the release key 113 more precisely and prevent it from tilting, jamming or swaying due to uneven force.

[0100] In some embodiments, such as Figure 3 As shown, in order to securely install the elastic element 114, the cavity wall of the receiving cavity 1122 is provided with a plug post 1124 extending into the receiving cavity 1122. One end of the elastic element 114 is sleeved on the plug post 1124, and the other end abuts against the release key 113.

[0101] An insertion post 1124 extending into the cavity 1122 is integrally formed or fixedly disposed on a cavity wall (usually the end wall facing the direction of movement of the release key 113) of the receiving cavity 1122. The insertion post 1124 can be a cylinder, a square post, etc.

[0102] One end (tail end) of the elastic element 114 (e.g., a compression spring) is directly sleeved on the outside of the insertion post 1124. The insertion post 1124 positions this end of the spring and prevents it from tilting. The other end (front end) of the elastic element 114 abuts against the corresponding surface of the release key 113. When the release key 113 moves the compression spring, the spring is smoothly compressed along the insertion post 1124 without buckling instability, ensuring a smooth and consistent reset action.

[0103] Furthermore, in some embodiments, such as Figure 3 As shown, in order to provide a more stable abutment point for the elastic element 114 on the release key 113, an abutment groove 1133 is provided on the surface of the release key 113 opposite to the insertion post 1124. This abutment groove 1133 can be a shallow recess or an annular groove.

[0104] During installation, one end (front end) of the elastic element 114 not only abuts against the surface of the release key 113, but its end can also be partially embedded in or aligned with the abutment groove 1133. In this way, both ends of the elastic element 114 are restricted by the insertion post 1124 and the abutment groove 1133 respectively, and its position is very stable throughout the compression and rebound process, further improving the reliability of the reset function.

[0105] In some embodiments, such as Figure 2 and Figure 3 As shown, in order to facilitate the manufacturing and assembly of the first fastener 112, the first fastener 112 includes a first panel 1125 and a first base plate 1126 that are mated together.

[0106] Specifically, the first fastener 112 adopts a modular design for easy manufacturing and assembly, and includes two main parts: a first panel 1125 and a first base plate 1126. The first panel 1125 is typically the user-facing housing portion with an operating window 1123, while the first base plate 1126 is the back cover. The first panel 1125 and the first base plate 1126 are "fitted together" using methods such as snap-fits, screws, or ultrasonic welding, that is, they are fastened together face to face.

[0107] The first panel 1125 and the first base plate 1126 mate to form a receiving cavity 1122. The release key 113 is installed in this receiving cavity 1122 formed by the first panel 1125 and the first base plate 1126, and its movement is limited by the common limit of these two components.

[0108] An operation window 1123 is disposed on the first panel 1125. The dimensions (length and width) of the operation window 1123 on the first panel 1125 are designed to be smaller than the projected dimensions of the release key 113 on the plane of the operation window 1123. That is, when viewed from a direction perpendicular to the operation window 1123, the outline of the release key 113 is larger than the window. Therefore, no matter how the release key 113 moves, its main body is locked in the plane by the edge of the operation window 1123, thereby limiting the movement of the release key 113 within the receiving cavity 1122 and preventing it from dislodging from the receiving cavity 1122. This is a simple and effective anti-dislodgement structure.

[0109] In some embodiments, such as Figure 2 and Figure 3 As shown, in order to achieve more precise alignment and accurately control the depth and shape of the receiving cavity 1122, the first panel 1125 is provided with an annular protrusion 11251, and the first base plate 1126 is mated and disposed on the annular protrusion 11251 to form the receiving cavity 1122. The area enclosed by the annular protrusion 11251 defines the boundary and depth of the receiving cavity 1122.

[0110] During assembly, the first base plate 1126 is fitted and fixed (e.g., by screwing onto the lugs of the flange, or by snap-fitting) onto the end face of the annular flange 11251. In this way, the annular flange 11251 of the first panel 1125 and the first base plate 1126 together form the receiving cavity 1122. The annular flange 11251 ensures the consistency of the depth of the receiving cavity 1122, provides precise sliding space for the release key 113, and also strengthens the structural strength of the panel. This design facilitates injection molding, assembly, and subsequent maintenance (simply by opening the base plate).

[0111] In some embodiments, such as Figure 2 As shown, in order to improve the convenience of locking operation, simplify the alignment operation during locking, and enhance the user experience, the locking assembly 12 is provided with a first magnet 121, and the male buckle 20 is provided with a second magnet 21; wherein, the first magnet 121 and the second magnet 21 can be magnetically attracted together along the engagement direction and can be separated, so that the male buckle 20 and the locking assembly 12 can be magnetically attracted together along the engagement direction and can be separated.

[0112] This embodiment introduces a magnetic assist function. A first magnet 121 is fixedly disposed inside the latch assembly 12 (typically located at the bottom of the lock hole or near the end of the bolt insertion path). Correspondingly, a second magnet 21 is also fixedly disposed inside the male latch 20 (e.g., at the head or inside of its bolt 23). The magnetic poles of the first magnet 121 and the second magnet 21 are arranged such that they are opposite poles (i.e., one N pole and one S pole) when they are close together, enabling them to generate a magnetic force that attracts each other.

[0113] When the user moves the male buckle 20 towards the engagement direction of the locking assembly 12, the magnetic attraction between the first magnet 121 and the second magnet 21 begins to take effect before they make physical contact. When they are a few centimeters or millimeters apart, the magnetic force becomes significant, automatically pulling the male buckle 20 to the correct mating position. The magnetic force automatically corrects the angle and positional deviation of the male buckle 20, guiding the latch precisely to align with the keyhole, and generating a continuous attraction force that draws the male buckle 20 towards the locking assembly 12 until the latch is fully inserted into the keyhole. This process greatly reduces the accuracy requirements for alignment, enabling blind operation and quick one-handed locking, making it particularly suitable for backpack buckles, case locks, and other similar applications.

[0114] Once locked, the magnetic force increases the initial holding force. To unlock, after direct or mechanical release, the user needs to apply a pulling force greater than the magnetic attraction to separate the two. The magnetic force can be selected as needed, providing convenient alignment assistance without making it too difficult to pull apart.

[0115] Furthermore, in some embodiments, such as Figure 2 and Figure 6 As shown, in order to further enhance the tensile locking, the male buckle 20 is provided with a locking groove 22, and the locking assembly 12 is provided with a locking part 122 corresponding to the locking groove 22; when the male buckle 20 and the locking assembly 12 are engaged in the engagement direction, the locking part 122 is engaged in the locking groove 22, so that the male buckle 20 cannot disengage from the locking assembly 12 in the opposite direction to the engagement direction.

[0116] A locking groove 22 is machined or formed on the male buckle 20. This locking groove 22 can be an annular groove, one or more recesses on the side, or a through hole. On the locking assembly 12, a locking part 122 is provided that corresponds to the locking groove 22 in position and shape. The locking part 122 can be a protrusion, a latch, or a spring.

[0117] When the male buckle 20 and the locking assembly 12 are fully engaged in the engagement direction with magnetic assistance, the locking part 122 will be engaged (or springed into) the locking groove 22 by the action of the mechanism (e.g., pushed by a spring or driven by magnetic force). Once the locking part 122 is engaged in the locking groove 22, the two form a mechanical interlock. At this time, if an attempt is made to pull the male buckle 20 directly in the opposite direction of engagement, the locking part 122 will be stuck in the locking groove 22, generating strong mechanical resistance, making it impossible for the male buckle 20 to be pulled open directly, thus achieving reliable locking. Unlocking requires operating the release operation assembly 11 to actively remove the locking part 122 from the locking groove 22, thereby releasing this mechanical interlock and allowing the male buckle 20 to be pulled open in the opposite direction of engagement.

[0118] In some embodiments, such as Figure 9 or Figure 11 As shown, the locking assembly 12 includes a second fixing member 123 and a moving member 124.

[0119] The second fastener 123 is the base of the locking assembly 12 and is fixedly installed on the product. It has a lock hole 1231 in the center for the male buckle 20 to be inserted. The male buckle 20 has a locking tongue 23 along the engagement direction that matches the shape of the lock hole 1231, and the locking tongue 23 has a locking groove 22.

[0120] A first magnet 121 is fixedly installed at the bottom of the keyhole 1231. A second magnet 21 is embedded in the corresponding position inside the latch 23 to assist in adsorption.

[0121] The movable part 124 is limited and positioned on the second fixed part (123) and can move relative to the second fixed part 123. The movable part 124 is a movable part in the locking assembly 12. It is limited and positioned on the second fixed part 123 by means of a slide rail, slide groove and other structures, so that the movable part 124 can only reciprocate relative to the second fixed part 123 in a specific direction (the horizontal direction perpendicular to the engagement direction).

[0122] The movable part 124 is provided with a locking part 122 and is connected to a remote release operation component 11 via a pull cable 13.

[0123] Locking process: The user aligns the latch 23 of the male buckle 20 with the lock hole 1231. The first magnet 121 and the second magnet 21 attract each other, guiding the latch 23 to be accurately inserted into the lock hole 1231 until it reaches the bottom. The locking part 122 on the moving part 124 moves and engages in the locking groove 22 on the latch 23, completing the mechanical locking.

[0124] Unlocking process: The user operates the release mechanism 11, transmitting a pulling force through the pull cord 13. This pulling force acts directly on the moving part 124. Under the action of the pulling force, the moving part 124 moves in a direction perpendicular to the engagement direction. This movement causes the locking part 122 on it to disengage from the locking groove 22. Once the locking part 122 disengages from the locking groove 22, only magnetic attraction remains between the latch 23 and the lock hole 1231. At this point, the user only needs to apply a small force to overcome the magnetic force to separate the male latch 20 from the locking assembly 12 in the opposite direction to the engagement direction, thus achieving disengagement.

[0125] In some embodiments, such as Figure 9-12 As shown, in order to reliably connect the pull cable 13 to the movable member 124, the movable member 124 has a second mounting part 1241 on the side opposite to the lock hole 1231, and the second mounting part 1241 has a second mounting hole 12411. The pull cable 13 is disposed in the second mounting hole 12411 and connected to the movable member 124.

[0126] A second mounting portion 1241 is provided on the side of the movable member 124 opposite to the lock hole 1231 (i.e., the back side). This second mounting portion 1241 is similar to the first mounting portion 111 and can be an annular flange, a column, or a protruding structure with a specific shape. A second mounting hole 12411 is provided on the second mounting portion 1241, which can be a through hole or a groove.

[0127] The end of the pull wire 13 is typically fitted with a plug larger than the hole diameter, using methods such as knotting, riveting, or using clips, and is securely placed within the second mounting hole 12411, thereby achieving an indirect fixed connection with the movable part 124. When the pull wire 13 is pulled, the pulling force is directly transmitted to the entire movable part 124 through the second mounting part 1241. This in-hole fixing method provides high connection strength, direct force transmission, and a simple structure, facilitating assembly.

[0128] Furthermore, in some embodiments, such as Figure 9-12As shown, in order to achieve the automatic locking function of insertion and locking, a third magnet 1242 is fixedly provided on the moving part 124. When the lock tongue 23 is inserted into the lock hole 1231, the second magnet 21 and the third magnet 1242 interact to drive the moving part 124 to move until the locking part 122 engages with the locking groove 22.

[0129] The magnetic pole orientation of the third magnet 1242 is designed. When the latch 23 moves into the lock hole 1231, in the first stage where the latch 23 enters the lock hole 1231 at its protruding top, the second magnet 21, located to the side of the third magnet 1242, forms a repulsive magnetic pole, causing the moving part 124 to move the locking part 122 away from the locking groove 22, facilitating the insertion of the latch 23. In the second stage, when the latch 23, carrying the second magnet 21, is inserted into the lock hole 1231 and gradually approaches its final position, the second magnet 21 inside the latch 23 and the third magnet 1242 on the moving part 124 enter the magnetic attraction range. Due to the arrangement of the magnetic poles, an attractive force is generated between the second magnet 21 and the third magnet 1242. This magnetic force drives the moving part 124 to move, causing the locking part 122 to approach and engage with the locking groove 22, achieving locking. This achieves automatic mechanical locking after the male latch 20 is inserted without additional user intervention, greatly improving ease of use and user experience. The entire process is fully automated, requiring no springs or other mechanical triggering mechanisms, and its structure is simple and reliable.

[0130] Furthermore, in some embodiments, such as Figure 9-12 As shown, in order to provide precise guidance and limit for the movement of the movable member 124, the second fixing member 123 is provided with a sliding groove 1232 on the side opposite to the locking hole 1231 for the second mounting part 1241 to be inserted. The sliding groove 1232 extends along the moving direction of the movable member 124, and the second mounting part 1241 can move within the sliding groove 1232.

[0131] The sliding groove 1232 is an elongated groove, guide rail, or through groove, which extends strictly in the direction that the moving part 124 needs to move.

[0132] The shape of the second mounting portion 1241 on the back of the movable component 124 matches the sliding groove 1232 (e.g., T-shaped, rectangular), and it is embedded in the sliding groove 1232. In this way, the second mounting portion 1241 (and the entire movable component 124) is constrained to move back and forth within the sliding groove 1232 along its length. The sidewall of the sliding groove 1232 acts as a guide, ensuring the straightness and accuracy of the movement trajectory of the movable component 124, and ensuring that the locking portion 122 can accurately align with and enter and exit the locking groove 22. This prevents the movable component from deflecting, tilting, or jamming during movement. Simultaneously, it also defines the starting and ending points of the movable component's stroke.

[0133] Furthermore, in some embodiments, such as Figure 8As shown, similar to the unlocking operation assembly 11, in order to orderly guide the pull cable 13 introduced from the outside and smoothly connect it to the second mounting portion 1241 within the sliding groove 1232, a second lead wire groove 1233 is also provided on the same side of the second fixing member 123 (the side opposite to the lock hole 1231). The second lead wire groove 1233 is used to guide the portion of the pull cable 13 connected to the second mounting portion 1241 along the moving direction of the moving member 124.

[0134] The second lead groove 1233 is a recess, channel, or extended wall groove, and its extension direction is also set along the moving direction of the moving member 124. The end of the tube 131 of the pull wire 13 from the release operation assembly 11 near the second fixing member 123 is fixed in the lead groove 1233, and the core wire 132 extends out from the tube 131 and is guided along the path of the second lead groove 1233 to pass through the sliding groove 1232 and connect to the second mounting part 1241 in the sliding groove 1232. This constrains it to a straight line or a smooth path parallel to the direction of movement, preventing the pull wire 13 from swinging, scraping, or bending excessively, ensuring smooth force transmission and component durability.

[0135] In some embodiments, such as Figure 8 As shown, in order to guide the core wire 132 guided in the second lead wire groove 1233 into the sliding groove 1232 and connect it with the second mounting part 1241, a wire hole is provided in the partition wall between the second lead wire groove 1233 and the sliding groove 1232.

[0136] During installation, the core wire 132 of the pull wire 13 passes through the end of the second lead wire groove 1233 and into the internal space of the adjacent sliding groove 1232 through this wire hole. Then, the end of the core wire 132 continues forward and is finally placed in the second mounting hole 12411. This structure makes the introduction of external cables and the connection of internal moving parts clear and orderly, and all wires are hidden and protected in the channel, resulting in a neat appearance and high reliability.

[0137] In some embodiments, such as Figure 9 and Figure 10 As shown, one specific embodiment of the movable member 124 is a ring arm 1243 structure. The movable member 124 is an entire ring arm 1243, which surrounds the outside of the keyhole 1231 and is movable relative to the keyhole 1231. The shape of this ring arm 1243 is generally one or more rectangular or circular frames, which correspondingly surround the outside of the keyhole 1231.

[0138] The annular arm 1243 has a locking part 122 on the side facing the lock hole 1231, which is used to cooperate with the locking groove 22 for mechanical locking.

[0139] The annular arm 1243 has a second mounting part 1241 on the side opposite to the lock hole 1231 for connecting the pull wire 13. The second mounting part 1241 cooperates with the sliding groove 1232 to guide the movement path, ensuring the straightness and accuracy of the movement trajectory of the annular arm 1243.

[0140] The annular arm 1243 is provided with a third magnet 1242, which interacts with the second magnet 21 to drive the annular arm 1243 to move to the locking part 122 and engage with the locking groove 22.

[0141] When the latch 23 is inserted into the lock hole 1231, the second magnet 21 inside interacts with the third magnet 1242 on the ring arm 1243. This magnetic force pulls the entire ring arm 1243 to translate towards the latch 23. As a result of the translation, the locking part 122 on the inner side of the ring arm 1243 moves to the opposite side of the locking groove 22 on the latch 23 and engages there, completing the locking.

[0142] When unlocking, pulling the cable 13 causes the second mounting part 1241 to move the ring arm 1243 in the opposite direction, disengaging the locking part 122 from the locking groove 22, so that the male buckle 20 can disengage from the locking assembly 12 in the opposite direction of engagement. The structure is simple and easy to assemble.

[0143] In some embodiments, such as Figure 10 and Figure 11 As shown, another specific embodiment of the movable member 124 includes a linkage block 1244 and a rotating arm 1245 rotatably mounted on the second fixed member 123.

[0144] The linkage block 1244 has a second mounting part 1241 on the side opposite to the lock hole 1231 for connecting the pull wire 13. The second mounting part 1241 cooperates with the sliding groove 1232 to guide the movement path, ensuring the straightness and accuracy of the movement trajectory of the linkage block 1244.

[0145] The linkage block 1244 is connected to the non-rotational center of the rotating arm 1245. Specifically, the rotating arm 1245 is rotatably mounted on the second fixed member 123 via a pivot or pivot point, allowing it to rotate around a fixed point. The linkage block 1244 is a linearly movable slider, connected to the pull wire 13 via the second mounting part 1241. The linkage block 1244 and the rotating arm 1245 are connected via a non-rotational center. For example, a pin or groove is provided on the rotating arm 1245 at a position away from the pivot, and a corresponding elongated hole or pin is provided on the linkage block 1244, forming a sliding pair or hinge, thereby converting the linear motion of the linkage block 1244 into the rotational motion of the rotating arm 1245.

[0146] The rotating arm 1245 has a locking part 122 at one end facing the lock hole 1231, which is used to cooperate with the locking groove 22 for mechanical locking.

[0147] The third magnet 1242 is disposed on the rotating arm 1245 and interacts with the second magnet 21 to drive the rotating arm 1245 to rotate until the locking part 122 engages with the locking groove 22.

[0148] When the latch 23 is inserted into the lock hole 1231, the second magnet 21 inside interacts with the third magnet 1242 on the rotating arm 1245. This magnetic force drives the rotating arm 1245 to rotate around its axis. The rotational motion causes the locking part 122 on the rotating arm 1245 to swing and engage in the locking groove 22 of the latch 23, thus completing the locking.

[0149] During unlocking, pulling the cable 13 causes the linkage block 1244 to move linearly. The linkage block 1244, through its connection point with the rotating arm 1245, pushes or pulls the rotating arm 1245, forcing it to rotate in the opposite direction, thereby disengaging the locking part 122 from the locking groove 22 and achieving unlocking. This design converts a small linear displacement into a large swing displacement at the end of the rotating arm, which is beneficial for layout in space-constrained situations.

[0150] In some embodiments, such as Figure 7 , Figure 9 , Figure 11 As shown, in a general structure of the locking assembly 12, the movable member 124 is movably and limitably disposed within the second fixed member 123. The locking hole 1231 has a locking hole 1234 on its groove wall, and the locking part 122 on the movable member 124 can extend into the locking hole 1231 through the locking hole 1234.

[0151] In order for the locking part 122 on the movable part 124 to extend into the lock hole 1231 and interact with the bolt 23, one or more locking holes 1234 are provided on the side wall groove of the lock hole 1231. These locking holes 1234 are through holes, which connect the interior of the lock hole 1231 with the space where the movable part 124 is located.

[0152] The locking portion 122 on the movable member 124 passes through the corresponding locking hole 1234, allowing its front end to extend into the lock hole 1231. When the latch 23 is inserted into the lock hole 1231 and moves to the correct position, its locking groove 22 aligns with the locking portion 122 passing through the locking hole 1234, and under the drive of the mechanism, the locking portion 122 engages in the locking groove 22.

[0153] Furthermore, in some embodiments, such as Figure 6 As shown, in order to provide more precise guidance when the latch 23 is inserted into the lock hole 1231, the protruding top of the latch 23 is provided with a guide protrusion 231 that can be inserted into the locking hole 1234. When the latch 23 is embedded in the lock hole 1231, the guide protrusion 231 corresponds to the locking hole 1234.

[0154] This guide protrusion 231 can be a small protrusion, a ridge, or a protrusion of a specific shape. During the insertion of the latch 23 into the lock hole 1231, this guide protrusion 231 will correspondingly insert into the locking hole 1234. This insertion and engagement provides precise positioning, ensuring that the latch 23 is not only axially in place but also at the correct circumferential angle, thus ensuring that the locking groove 22 is aligned with the path of the locking part 122. This is particularly suitable for scenarios where it is necessary to prevent the male latch 20 from being incorrectly rotated during insertion, improving the reliability and success rate of the locking mechanism.

[0155] In some embodiments, such as Figure 9 or Figure 11 As shown, similar to the first fastener 112, the second fastener 123 can also adopt a modular design with interlocking components. It includes a second panel 1235 and a second base plate 1236.

[0156] The movable component 124 is movably positioned within the receiving space formed by the mating of the second panel 1235 and the second base plate 1236. The second panel 1235 is typically the outer shell portion facing the male buckle 20 and having a locking hole 1231. The second panel 1235 and the second base plate 1236 are mated and fixed together, and the cavity formed between them is the receiving space. The movable component 124 is installed and confined within this receiving space.

[0157] The second panel 1235 is provided with a lock hole 1231 recessed toward the second base plate 1236. The lock hole 1231 is formed by recessing toward the second base plate 1236, that is, a recessed structure in the form of a pit or through hole stamped or injection molded on the second panel 1235.

[0158] The second base plate 1236 has a sliding groove 1232 on the side opposite to the lock hole 1231, and a second lead wire groove 1233 on the side opposite to the lock hole 1231. The functions of the sliding groove 1232 and the second lead wire groove 1233 are the same as in the above embodiment, and will not be repeated here.

[0159] Furthermore, in some embodiments, such as Figure 2 , Figure 9 , Figure 11 As shown, in order to prevent the pull wire 13 installed in the sliding groove 1232 and the second lead wire groove 1233 from coming out from the top of the groove (i.e., the open side), the sliding groove 1232 and the second lead wire groove 1233 are provided with face buckles 1237. The face buckles 1237 seal the top surface of the sliding groove 1232 and the second lead wire groove 1233 to limit the pull wire 13 from coming out from the top surface of the sliding groove 1232 and the second lead wire groove 1233.

[0160] The faceplate 1237 is either an independent cover or a flip-top structure integrally formed with the second fixing member 123. It is fitted onto the sliding groove 1232 and the second lead wire groove 1233 and secured by snaps or screws. When the faceplate 1237 is closed, it seals the top surfaces of the sliding groove 1232 and the second lead wire groove 1233, making these two grooves into closed-top pipes or channels. In this way, the pull wire 13 is safely confined within the groove, unable to escape upwards, and can only move along the length of the groove, further ensuring the stability and durability of the transmission mechanism.
