The bag with the magnetic buckle includes a telescopic magnetic buckle and a bag body. The surface of the bag body has a recessed receiving groove, and the telescopic magnetic buckle is disposed in the receiving groove, with the housing flush with the surface of the bag body. This movable latch mechanism not only completely eliminates the security risks caused by a protruding latch, but also ensures the surface flatness and aesthetics of the telescopic magnetic buckle and the bag with the magnetic buckle during transport, handling, and daily storage, significantly improving the user experience and product reliability.

Description

Technical Field

[0001] This invention relates to the field of fasteners, and more particularly to a telescopic magnetic buckle and a bag with a magnetic buckle. Background Technology

[0002] In the field of fastener technology, the locking tongue, as the core component for achieving the locking function, directly determines the performance and appearance of the fastener. In existing fastener designs, to ensure the locking tongue can smoothly insert into the locking hole or slot of the mating part to complete the locking, the locking tongue is usually designed as a rigid protruding structure, always remaining protruding from the outer surface of the fastener housing. While this "always protruding" design can meet basic connection functions, it reveals significant shortcomings in practical applications, especially in scenarios where a smooth product appearance and portability are highly demanding.

[0003] Taking magnetic connection applications in the luggage industry as an example, with the diversification of travel needs, users often need to carry multiple suitcases. To achieve multi-suitcase coordinated movement, a connection solution using male and female magnetic locking buckles has emerged on the market. In this solution, the male buckle is installed on the surface of one suitcase, and the female buckle is installed on the surface of another suitcase. However, limited by the structural design of traditional buckles, the locking tongue on the male buckle must protrude from the surface of the suitcase to be ready to be inserted into the locking hole of the female buckle. This protruding locking tongue design brings the following main problems in actual use.

[0004] First, suitcases frequently face crowded, stacked, or bumpy environments during check-in, handling, or daily storage. The rigid latch protruding from the suitcase surface easily becomes a stress point, scraping against the surrounding environment or other luggage. This not only easily leads to deformation or breakage of the latch itself, causing the fastener to malfunction, but may also scratch the suitcase surface or other valuables, reducing the product's durability. Second, modern suitcase designs increasingly pursue a simple and streamlined visual effect. A protruding latch disrupts the flatness and continuity of the suitcase surface, making the suitcase appear abrupt and preventing a completely integrated design. This structural disharmony lowers the overall quality and grade of the product, failing to meet consumers' pursuit of a high-quality appearance. Summary of the Invention

[0005] The present invention aims to solve the above problems and provides a telescopic magnetic buckle that can be stored inside the housing and keep the surface flat when not connected, and can be reliably extended when connected, as well as a bag equipped with the telescopic magnetic buckle.

[0006] To address the above problems, the present invention provides a telescopic magnetic buckle, characterized in that it comprises:

[0007] A housing, wherein a locking tongue hole is provided on the housing;

[0008] A locking component is provided with a latch portion, and a first magnet is provided inside the latch portion. The locking component is movably disposed within the housing and can move along a first direction to switch between an extended state and a retracted state. In the extended state, the latch portion passes through the latch hole and protrudes from the surface of the housing. In the retracted state, the latch portion is retracted into the housing and does not protrude from the surface of the housing.

[0009] Furthermore, the housing is also provided with an elastic reset member, which is used to drive the locking member to switch from the extended state to the retracted state.

[0010] Furthermore, a second magnet is provided inside the housing, which cooperates with the first magnet to drive the locking component to switch from the extended state to the retracted state.

[0011] Furthermore, the housing includes a first housing and a second housing that are fixedly connected, the locking component is located between the first housing and the second housing, the locking tongue hole is provided in the first housing, the first housing is provided with a stud portion arranged along the first direction, the second housing is provided with a first clearance hole, the locking component is provided with a limiting hole, and the stud portion passes through the limiting hole and the first clearance hole in sequence.

[0012] Furthermore, the two ends of the elastic reset member abut against the locking member and the first housing, respectively.

[0013] Furthermore, the line connecting the second magnet and the first magnet is parallel to the first direction.

[0014] Furthermore, the locking member is provided with a recessed first limiting part, the first housing is provided with a recessed second limiting part, the first limiting part and the second limiting part are arranged opposite to each other, and the two ends of the elastic reset member abut against the first limiting part and the second limiting part respectively.

[0015] Furthermore, the elastic reset member is a tower spring, with the small-diameter end of the tower spring abutting the first limiting part and the large-diameter end of the tower spring abutting the second limiting part.

[0016] Furthermore, the first housing is provided with a protruding first connecting shaft portion, the first connecting shaft portion having a first connecting hole, the second housing is provided with a second connecting shaft portion, the second connecting shaft portion having a second connecting hole, the ends of the first connecting shaft portion and the ends of the second connecting shaft portion abutting each other, and the first housing and the second housing are fixedly connected through the first connecting hole, the second connecting hole and fasteners.

[0017] The present invention also provides a bag with a magnetic buckle, which includes the aforementioned telescopic magnetic buckle and a bag body. The surface of the bag body is provided with a recessed receiving groove, the telescopic magnetic buckle is disposed in the receiving groove, and the housing does not protrude from the surface of the bag body. In the extended state, the locking tongue of the telescopic magnetic buckle protrudes from the surface of the bag body. In the retracted state, the locking tongue of the telescopic magnetic buckle is retracted into the housing and does not protrude from the surface of the bag body.

[0018] The beneficial contribution of this invention lies in its effective solution to the technical problem of traditional fasteners where the locking tongue is easily exposed to other objects and prone to collisions, scratches, or even structural deformation when not in a connected state. This invention innovatively employs a concealed telescopic structure, allowing the locking tongue to be movably housed inside the housing, and uses a reset component (elastic reset component or magnet) to automatically switch the locking tongue's state. When connection with an external mating component is required, the locking tongue can smoothly pass through the locking tongue hole on the housing and protrude from the housing surface for quick locking with the external mating component; when no connection is needed or when unlocking is required, the locking tongue can automatically retract under the action of the reset component, completely retracting inside the housing, with its end face flush with or slightly lower than the housing surface. The bag with magnetic clasp includes a telescopic magnetic clasp and a bag body. The bag body has a recessed receiving groove on its surface, within which the telescopic magnetic clasp is located. The housing is flush with the bag body surface, allowing the locking tongue to retract inside the housing and not protrude from the bag body surface when not in use. This movable locking tongue mechanism not only completely eliminates the safety hazards of a protruding locking tongue and ensures a smooth and aesthetically pleasing surface for the telescopic magnetic clasp and the bag during transport, handling, and daily storage, but also effectively extends the overall lifespan of the telescopic magnetic clasp and the bag, significantly improving the user experience and product reliability.

Detailed Implementation

[0025] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0026] like Figures 1-5 As shown, a telescopic magnetic buckle can be locked and fixed with a mating part having a lock hole, mainly used for connecting and fixing objects such as suitcases and handbags. The telescopic magnetic buckle includes a housing 10 and a locking component 20. The housing 10 serves as an integral support component and is usually fixed to the suitcase. The housing 10 has a locking tongue hole 111. The housing 10 has an internal receiving space for accommodating the locking component 20. The locking component 20 is movably disposed within the receiving space of the housing 10. The locking component 20 has a base plate portion 22 and a locking tongue portion 21 protruding from the surface of the base plate portion 22 along a first direction. The position of the locking tongue portion 21 corresponds to the locking tongue hole 111. The locking component 20 can slide relative to the housing 10 along the first direction, thereby switching between an "extended state" and a "retracted state". In the extended state: the locking tongue portion 21 passes through the locking tongue hole 111 and protrudes from the surface of the housing 10. At this time, the locking tongue 21 of the telescopic magnetic buckle can be inserted into the lock hole of the mating part, and the telescopic magnetic buckle and the mating part are locked together. The design of the locking tongue 21 being inserted into the lock hole to achieve locking is a common design in the field of buckles. The locking principle will not be described in detail here, but can be referred to the relevant patents previously applied for by the applicant. In the storage state: When not locked with the mating part, the lock is in the storage state by default. The locking tongue 21 is completely stored inside the housing 10 and does not protrude from the surface of the housing 10, and is even slightly lower than the surface of the housing 10. This design keeps the surface of the telescopic magnetic buckle flat, effectively avoiding scratches, deformation or damage caused by the protrusion of the locking tongue 21 during transportation, handling or daily storage, thereby completely eliminating the safety hazards caused by the protruding structure.

[0027] To achieve the automatic extension function, a first magnet is embedded inside the locking component 20, specifically, the first magnet is located inside the latch portion 21. Correspondingly, a third magnet is provided inside the mating component that matches the telescopic magnetic buckle. When the mating component approaches the telescopic magnetic buckle, the first magnet and the third magnet attract each other, and the locking component 20 moves along a first direction under the magnetic attraction of the first magnet and the third magnet. Part of the latch portion 21 passes through the latch hole 111 and protrudes from the surface of the housing 10, and the locking component 20 changes from a retracted state to an extended state. In the extended state, the latch portion 21 can cooperate with the mating component to achieve locking. Specifically, the latch portion 21 has a locking groove, and the mating component has a locking part. After the latch portion 21 is inserted into the lock hole, the locking part cooperates with the locking groove, preventing the latch from disengaging from the lock hole, thereby achieving locking between the telescopic magnetic buckle and the mating component. When the telescopic magnetic buckle is unlocked from the mating component, as the mating component moves away from the telescopic magnetic buckle, the external magnetic attraction weakens and eventually disappears. At this time, the locking member 20 moves along the first direction until the latch 21 is completely retracted into the storage space of the housing 10. The locking member 20 smoothly transitions from the extended state to the retracted state, restoring the smooth appearance of the surface. Under no external force, the locking member 20 is in the retracted state. The locking and unlocking of the latch 21 and the mating member is a common technique in the field of fasteners and will not be described further here.

[0028] Furthermore, the number of the latch hole 111 and the latch portion 21 are consistent. In this embodiment, the housing 10 is provided with two latch holes 111, and the locking component 20 is provided with two latch portions 21.

[0029] Furthermore, in order to ensure that the locking member 20 can be stably and automatically maintained in the retracted state when there is no external force, in some embodiments, the housing 10 is provided with an elastic reset member 30. The elastic reset member 30 is disposed between the locking member 20 and the housing 10. Specifically, its two ends abut against the base plate portion 22 and the housing 10 respectively, to provide a continuous reset force to drive the locking member 20 to switch from the extended state to the retracted state.

[0030] Furthermore, in order to ensure that the locking component 20 can be stably and automatically kept in the retracted state when there is no external force, in some embodiments, a second magnet is provided inside the housing 10. The second magnet cooperates with the first magnet to drive the locking component 20 to switch from the extended state to the retracted state.

[0031] Furthermore, in order to precisely constrain the movement trajectory of the locking component 20 and facilitate the assembly of the telescopic magnetic buckle, the housing 10 includes a first housing 11 and a second housing 12 fixedly connected, which together form the receiving space. The locking component 20 is located between the first housing 11 and the second housing 12. The locking tongue hole 111 is provided in the first housing 11. The first housing 11 is provided with a stud portion 112 arranged along the first direction. The second housing 12 is provided with a first clearance hole 121. The base plate portion 22 is provided with a limiting hole 221. The stud portion 112 passes through the limiting hole 221 and the first clearance hole 121 in sequence, and the overhanging end of the stud portion 112 protrudes from the surface of the second housing 12. The design of the stud portion 112 passing through the limiting hole 221 strictly restricts the locking member 20 to linear reciprocating movement in the first direction, effectively preventing radial offset or circumferential rotation during displacement, thereby ensuring that the locking tongue portion 21 can be accurately aligned with and pass through the locking tongue hole 111, avoiding movement jamming.

[0032] Furthermore, the design of the protruding end of the stud portion 112 protruding from the surface of the second housing 12 allows the stud portion 112 to also serve as a mounting and fixing function. The stud portion 112 is provided with a threaded hole, and during actual assembly, the stud portion 112 can be fixed to the surface of the bag by engaging with a screw through the threaded hole.

[0033] The number of stud portions 112 is not limited. In this embodiment, there are four stud portions 112, and the line connecting the four stud portions 112 forms a rectangle. The number and arrangement of the first clearance hole 121 and the limiting hole 221 are consistent with those of the stud portions 112.

[0034] Furthermore, the elastic reset member 30 can be disposed between the first housing 11 and the substrate portion 22, or it can be disposed between the second housing 12 and the substrate portion 22.

[0035] When the elastic reset member 30 is disposed between the first housing 11 and the base plate portion 22, both ends of the elastic reset member 30 abut against the base plate portion 22 and the first housing 11, respectively. During dynamic operation, when the locking member 20 is subjected to external magnetic attraction and changes from the retracted state to the extended state, the locking member 20 slides along the first direction closer to the latch hole 111. At this time, the distance between the locking member 20 and the first housing 11 in the first direction gradually decreases, and the elastic reset member 30 is continuously compressed, thereby accumulating elastic potential energy inside it. When the external magnetic attraction disappears or the external force decreases to an insufficient level to overcome the elastic force of the elastic reset member 30, the elastic reset member 30 begins to release the accumulated elastic potential energy. Driven by the elastic reset force, the locking member 20 moves away from the first housing 11 along the first direction until the latch portion 21 is completely retracted into the storage space of the housing 10. Preferably, the elastic reset member 30 is still in a compressed state at this time. When the elastic reset member 30 is disposed between the second housing 12 and the base plate portion 22, both ends of the elastic reset member 30 are connected to the base plate portion 22 and the second housing 12, respectively. During dynamic operation, when the locking member 20 is subjected to external magnetic attraction and changes from the retracted state to the extended state, the locking member 20 slides along the first direction closer to the latch hole 111. At this time, the distance between the locking member 20 and the second housing 12 in the first direction gradually increases, and the elastic reset member 30 is continuously stretched, thereby accumulating elastic potential energy inside it. When the external magnetic attraction disappears, or the external force decreases to an insufficient level to overcome the elastic force of the elastic reset member 30, the elastic reset member 30 begins to release the accumulated elastic potential energy. Driven by the elastic reset force, the locking member 20 moves closer to the second housing 12 along the first direction until the latch portion 21 is completely retracted into the storage space of the housing 10. Whether the elastic reset member 30 is located between the first housing 11 and the locking member 20, or between the second housing 12 and the locking member 20, the locking member 20 can be automatically and smoothly converted from the extended state to the retracted state through the mechanical reset mechanism of the elastic reset member 30, ensuring that the telescopic magnetic buckle always maintains a flat and secure appearance when not connected.

[0036] Preferably, the elastic reset member 30 is disposed between the first housing 11 and the locking member 20. There are two elastic reset members 30, located at opposite ends of the locking member 20 along the line connecting the two latch portions 21, i.e., the line connecting the two latch portions 21 and the two elastic reset members 30 forms a straight line, and the two latch portions 21 are located between the two elastic reset members 30. Furthermore, one elastic reset member 30 is positioned on the line connecting the two limiting holes 221.

[0037] Furthermore, in the embodiment where the locking member 20 is stabilized within the receiving space without external force using a second magnet, to ensure the stability of the locking member 20 within the receiving space and the effect of the locking member 20 moving from the extended state to the retracted state, the line connecting the second magnet and the first magnet is parallel to the first direction. More specifically, the second magnet is located within the second housing 12, and the first and second magnets attract each other. When the locking member 20 is subjected to an external magnetic force, and this external magnetic force is greater than the magnetic force between the first and second magnets, the locking member 20 slides along the first direction towards the latch hole 111, changing from the retracted state to the extended state. When the external magnetic force disappears or decreases to less than the magnetic force between the first and second magnets, under the action of the magnetic force between the first and second magnets, the locking member 20 moves along the first direction towards the second housing 12, and the latch portion 21 is completely retracted within the receiving space of the housing 10.

[0038] Furthermore, to achieve precise positioning and stable engagement of the elastic reset member 30, the locking member 20 is provided with a recessed first limiting portion 222. Specifically, the first limiting portion 222 is located in the base plate portion 22. The first housing 11 is provided with a recessed second limiting portion 114, and the first limiting portion 222 and the second limiting portion 114 are arranged opposite to each other. The line connecting the opposing first limiting portion 222 and the second limiting portion 114 is parallel to a first direction. Both ends of the elastic reset member 30 are respectively accommodated and abut against the first limiting portion 222 and the second limiting portion 114.

[0039] Specifically, the recessed shapes of the first limiting portion 222 and the second limiting portion 114 are adapted to the end contour of the elastic reset member 30. This structural fit effectively limits the radial displacement of the elastic reset member 30 during compression and release, preventing it from tilting or dislodging. When the locking member 20 moves to the extended state along the first direction, the elastic reset member 30 is compressed and stores energy between the first limiting portion 222 and the second limiting portion 114. When the external force is removed, the elastic reset member 30 uses the stored elastic potential energy to smoothly reset the locking member 20 to the retracted state along the first direction. This limiting structure significantly improves the reset reliability and structural stability of the telescopic magnetic buckle during long-term repeated use.

[0040] Further, the elastic reset member 30 is preferably a tower spring, which is disposed between the first limiting part 222 and the second limiting part 114 along the first direction. Specifically, the small-diameter end of the tower spring abuts against the first limiting part 222 on the locking member 20, and the large-diameter end of the tower spring abuts against the second limiting part 114 on the housing 10. Utilizing the conical structure of the tower spring, its small-diameter end is positioned towards the locking member 20, and its large-diameter end is positioned towards the housing 10. After the tower spring is compressed, the small-diameter end can be located inside the large-diameter end. This arrangement can effectively adapt to the narrow internal space of the telescopic magnetic buckle, ensuring sufficient reset elasticity while significantly reducing the overall thickness of the telescopic magnetic buckle, which is beneficial for achieving a thinner and lighter product design. In addition, the large-diameter end of the tower spring has a larger support area, which can provide more stable bottom support when abutting against the second limiting part 114, effectively preventing the spring from tilting or tipping over during compression, thereby ensuring the smooth movement of the locking member 20 along the first direction. When the tower spring is fully compressed, its coils can nest together (i.e., the smaller diameter coil is tucked into the larger diameter coil), resulting in minimal spring compression height. This characteristic provides more leeway for the travel of the locking element 20, ensuring that the latch 21 can fully extend / retract, ensuring stability during connection and flatness of the telescopic magnetic buckle surface when not connected.

[0041] Furthermore, to achieve the connection between the first housing 11 and the second housing 12, the first housing 11 is also provided with a protruding first connecting shaft portion 113, which has a first connecting hole. The second housing 12 is provided with a second connecting shaft portion 122, which has a second connecting hole. The ends of the first connecting shaft portion 113 and the second connecting shaft portion 122 abut against each other, and the first housing 11 and the second housing 12 are connected through the first connecting hole, the second connecting hole, and fasteners. Specifically, the inner walls of both the first connecting hole and the second connecting hole are provided with threads, and the fasteners are screws. The first connecting shaft portion 113 and the second connecting shaft portion 122 are connected together by screws to achieve a fixed connection between the second housing 12 and the second housing 12. A second clearance hole 223 is provided on the base plate portion 22 at a position corresponding to the first connecting shaft and the second connecting shaft portion 122. Both the first connecting shaft portion 113 and the second connecting shaft portion 122 pass through the second clearance hole 223. Furthermore, the second housing 12 is also provided with a receiving groove 123, which communicates with the second connecting hole. The screw shank passes through the receiving groove 123, the second connecting hole and the second connecting hole in sequence, and the screw head is located in the receiving groove 123, so that the screw does not protrude from the surface of the second housing 12.

[0042] A bag with a magnetic buckle includes a bag body and the telescopic magnetic buckle. Specifically, the surface of the bag body is provided with a recessed receiving groove, the telescopic magnetic buckle is partially disposed in the receiving groove, and the shell 10 is flush with the surface of the bag body. Specifically, the shell 10 does not protrude from the surface of the bag body, and preferably the shell 10 is flush with the surface of the non-recessed area of ​​the bag body.

[0043] In its extended state, the latch 21 of the telescopic magnetic buckle protrudes from the surface of the bag body. In its retracted state, the latch 21 is retracted inside the housing 10 and does not protrude from the surface of the bag body. The bag with the magnetic buckle can be connected to another bag with a mating part through the locking of the telescopic magnetic buckle and the mating part, facilitating the carrying of multiple bags. In its normally retracted state, the latch 21 is hidden inside the housing 10, and the housing 10 does not protrude from the surface of the bag body, ensuring the flat and aesthetically pleasing appearance of the bag with the magnetic buckle. When connecting a bag with a magnetic clasp and a bag with a mating component, the magnetic attraction pulls the locking component 20 to move. The locking tongue 21 passes through the locking tongue hole 111 and protrudes from the surface of the bag with the magnetic clasp, thus locking with the mating component. To separate, the mating component is unlocked, and the locking component 20 moves along a first direction under the action of the elastic reset member 30 / second magnet, allowing the lock to be stored within the receiving space and not protruding from the surface of the bag body. The unlocking method of the telescopic magnetic clasp and the mating component is a common design in the art and will not be described in detail here. More specifically, the receiving groove has a mounting hole, and the stud is connected to the mounting hole by bolts or other fasteners.

[0044] Furthermore, the first housing 11 and the locking element 20 are housed together in the receiving groove of the bag body, while the second housing 12 is located on the back side of the receiving groove. Thus, the locking element 20 and the second housing 12 are located on opposite sides of the bag body structure, forming a clamping state. The entire telescopic magnetic buckle is fixed in the receiving groove by fasteners. Specifically, the housing 10 is secured to the receiving groove of the bag body by screws. These screws pass through from the side where the second housing 12 is located and are ultimately locked into the stud portion 112 and / or the first connecting shaft portion 113 of the first housing 11, thereby achieving a fixed connection between the first housing 11, the second housing 12, and the bag body.

[0045] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
