A magnetic fastener includes a female fastener and a male fastener. The female fastener has a lock hole, a locking element, and a first magnetic element. The male fastener has a latch and a second magnetic element. The first and second magnetic elements attract each other in the locking direction. The invention is characterized by a third magnetic element within the female fastener. In the first stage of the latch insertion into the lock hole in the locking direction, the magnetic force between the third and second magnetic elements drives the locking element to move to a first position in a first direction perpendicular to the locking direction or keeps the locking element in the first position. In the second stage of the latch insertion into the lock hole in the locking direction, the magnetic force between the third and second magnetic elements drives the locking element to move from the first position to a second position in a second direction perpendicular to the locking direction, thus engaging with the latch. This invention greatly simplifies the structure of the locking element and reduces its size, thereby facilitating miniaturization and expanding its application range.

Description

Technical Field

[0001] This invention relates to safety buckles, and more particularly to a magnetic buckle. Prior Technology

[0002] A safety latch typically consists of a female latch and a male latch. The male latch has a locking bolt, and the female latch has a locking hole. The locking bolt is inserted into the locking hole to lock the male and female latches together. By operating the unlocking mechanism, the male and female latches can be separated.

[0003] Generally, the locking structure on a female buckle consists of a keyhole and a repositionable locking part. When the locking part extends into the keyhole, it acts as a latch, locking the bolt within the keyhole, thus connecting the male and female buckles. When the locking part retracts from the keyhole, the bolt can freely enter and exit the keyhole, allowing the male and female buckles to separate.

[0004] When the male and female latches are inserted, the bolt usually presses against the locking part. The bolt's pressure forces the locking part to move aside, allowing the bolt to continue advancing. When the bolt is fully inserted into the keyhole, the locking part must automatically return to its original position to lock the bolt, achieving a locking connection between the male and female latches. Therefore, during the bolt insertion process, the locking part, after being passively moved aside, needs to automatically return to its original position for locking. Thus, existing safety latches require a spring-loaded component in the female latch. This spring force provides an opportunity for the locking part to move, allowing it to be pushed by the bolt and automatically locking using the spring force. For example, ZL201910147794.7. Summary of the Invention

[0005] The present invention aims to solve the above problems and provides a magnetic fastener that uses the magnetic force of a magnetic component to move and lock the locking part, thereby saving installation space and facilitating miniaturization.

[0007] The female buckle is equipped with a locking hole, a locking mechanism, and a first magnetic component;

[0008] The male buckle is equipped with a locking tongue and a second magnetic component;

[0009] The latch can be inserted into the keyhole in the locking direction to engage with the locking member, so that the male and female latches are engaged together. The first and second magnetic members attract each other in the locking direction.

[0010] Its features are,

[0011] A third magnetic element is provided inside the female buckle.

[0012] In the first stage of the process of the bolt being inserted into the keyhole along the locking direction, the magnetic force between the third magnetic element and the second magnetic element can drive the locking element to move to a first position along a first direction perpendicular to the locking direction or keep the locking element in the first position;

[0013] In the second stage of the process of inserting the latch into the lock hole along the locking direction, the magnetic force between the third magnetic element and the second magnetic element can drive the locking element to move from the first position to the second position along a second direction perpendicular to the locking direction and engage with the latch.

[0014] Furthermore, in the first stage, the magnetic force between the third magnetic component and the second magnetic component is a magnetic repulsion force; in the second stage, the magnetic force between the third magnetic component and the second magnetic component is a magnetic attraction force.

[0015] Furthermore, the locking element and the third magnetic element are linked together.

[0016] Furthermore, the locking component is a rigid structure, and the third magnetic component is fixedly mounted on the locking component.

[0017] Furthermore, the locking element includes a fixed connection or an integrally formed component:

[0019] The unlocking part is partially exposed outside the housing of the female buckle and can be used for unlocking operations;

[0020] The magnet mounting part is provided with a magnet mounting groove, and the third magnetic component is installed in the magnet mounting groove.

[0021] Furthermore, the locking component also includes an annular enclosure, with the locking part and the unlocking part respectively disposed on the enclosure and spaced apart from each other.

[0022] Furthermore, the female buckle is provided with an unlocking component, which can move along a third direction perpendicular to the locking direction;

[0026] The linkage unit is linked with the unlocking component, and can be actuated under the linkage of the unlocking component to move the locking component from the second position to the first position.

[0027] Furthermore, the first direction and the second direction are parallel, and the third direction is perpendicular to the first direction and the second direction.

[0028] Furthermore, the unlocking component includes pressing parts that can be pressed in opposite directions, and elastic arms connected between the pressing parts. A linkage post extending along the locking direction is provided on the elastic arm. The linkage part has an action surface facing the linkage post, and the action surface is set at an angle with the first direction and the third direction.

[0029] Furthermore, the linkage column is symmetrically arranged on the elastic arm with the first direction as the axis of symmetry, and the linkage part is symmetrically arranged at the end of the magnet mounting part away from the locking part with the first direction as the axis of symmetry.

[0030] The beneficial contribution of this invention lies in its effective solution to the aforementioned problems. The magnetic fastener of this invention replaces the elastic component in the prior art with a third magnetic element. The locking mechanism is actuated by the interaction between the third magnetic element and the second magnetic element in the latch, thereby simplifying the structure of the locking component, facilitating miniaturization, and expanding its application range. The magnetic fastener of this invention features a novel structure and practical function, making it highly practical and worthy of widespread promotion. Simple Explanation of the Diagram

[0032] Figure 2 is a structural schematic diagram of Embodiment 1.

[0033] Figure 3 is a structural schematic diagram of Example 2.

[0034] Figure 4 is a structural schematic diagram of Example 2. Implementation

[0035] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0036] As shown in Figures 1 to 4, the magnetic fastener of the present invention includes a male fastener 10 and a female fastener 20. Its main feature is that a third magnetic element 23 is provided in the female fastener 20. The interaction between the third magnetic element 23 and the second magnetic element 12 in the locking tongue 11 is used to actuate the locking element 22 to achieve locking.

[0037] As shown in Figures 1-4, the male buckle 10 and female buckle 20 can be locked together and can also be separated. The male buckle 10 is provided with a locking tongue 11, and the female buckle 20 is provided with a corresponding locking hole 24. The locking tongue 11 can be inserted into the locking hole 24 in the locking direction to lock the male buckle 10 and female buckle 20 together. During the unlocking operation, the locking tongue 11 can be withdrawn from the locking hole 24 to separate the male buckle 10 and female buckle 20.

[0038] As shown in Figures 1-4, the female buckle 20 is provided with a first magnetic element 21, and the male buckle 10 is provided with a second magnetic element 12. The first magnetic element 21 and the second magnetic element 12 attract each other in the locking direction of the male buckle 10 and the female buckle 20. When the male buckle 10 and the female buckle 20 approach each other to a certain distance, the first magnetic element 21 and the second magnetic element 12 attract each other, allowing the bolt 11 to be quickly inserted into the lock hole 24.

[0039] As shown in Figures 1-4, the position of the first magnetic element 21 corresponds to the position of the keyhole 24. The position of the second magnetic element 12 corresponds to the position of the latch 11. Normally, the second magnetic element 12 is located within the latch 11.

[0040] The shapes of the first magnetic element 21 and the second magnetic element 12 are not limited, but preferably they are the same shape. In this embodiment, the first magnetic element 21 and the second magnetic element 12 are circular magnets.

[0041] As shown in Figures 1-4, the locking tongue 11 is a locking latch, and a locking element 22 is provided inside the female latch 20. The locking element 22 is movably disposed within the female latch 20.

[0042] As shown in Figures 1-4, the locking member 22 is provided with a locking part 221. When the locking part 221 extends out of the lock hole 24, it has the ability to lock the bolt 11. At this time, the locking part 221 can lock the bolt 11, thereby locking the male buckle 10 and the female buckle 20 together. When the locking part 221 moves to a certain extent in the direction of exiting the lock hole 24, for example, when it completely exits the range of the lock hole 24, the locking part 221 loses its ability to lock the bolt 11, and at this time the male buckle 10 and the female buckle 20 can be separated from each other.

[0043] As shown in Figures 1-4, a third magnetic element 23 is provided on the locking member 22 to prevent the locking part 221 from being actuated by an elastic component. The position of the third magnetic element 23 relative to the locking member 22 is fixed.

[0044] During the first stage of the process of the locking tongue 11 being inserted into the lock hole 24 along the locking direction, the magnetic force between the third magnetic element 23 and the second magnetic element 12 can drive the locking element 22 to move to a first position along a first direction perpendicular to the locking direction or keep the locking element 22 in the first position;

[0045] In the second stage of the process of inserting the latch 11 into the lock hole 24 along the locking direction, the magnetic force between the third magnetic element 23 and the second magnetic element 12 can drive the locking element 22 to move from the first position to the second position along a second direction perpendicular to the locking direction and engage with the latch 11.

[0046] During the first and second stages, the change in the magnetic properties between the third magnetic element 23 and the second magnetic element 12 is caused by changes in distance and position. The magnetic properties of the third magnetic element 23 and the second magnetic element 12 themselves do not change. However, as the latch 11 is inserted into the keyhole 24, the position of the latch 11 relative to the keyhole 24 changes. Consequently, the position and distance of the second magnetic element 12 relative to the third magnetic element 23 also change, leading to a change in the magnetic properties between the third magnetic element 23 and the second magnetic element 12.

[0047] In this embodiment, during the first stage, the magnetic force between the third magnetic element 23 and the second magnetic element 12 is a magnetic repulsion force. Therefore, during the first stage, the second magnetic element 12 repels the third magnetic element 23, causing the locking element 22 to remain in the first position, or to move to the first position along the first direction, while remaining away from the latch 11. In the first position, the locking part 221 is not within the range of the lock hole 24, and the locking part 221 cannot engage with the latch 11, nor will it obstruct the latch 11 from entering the lock hole 24.

[0048] In the second stage, the magnetic force between the third magnetic element 23 and the second magnetic element 12 is a magnetic attraction force. Therefore, in the second stage, the second magnetic element 12 attracts the third magnetic element 23, actuating the locking element 22, causing the locking element 22 to move from the first position to the second position along the second direction. In the second position, the locking part 221 is within the range of the lock hole 24, and the locking part 221 engages with the lock tongue 11, thereby engaging the male buckle 10 and the female buckle 20 together.

[0049] The first direction and the second direction are two parallel and opposite directions. The first direction is the direction in which the locking part 221 moves away from the lock hole 24. The second direction is the direction in which the locking part 221 enters the lock hole 24.

[0050] During the insertion of the latch 11 into the lock hole 24, the magnetic force of the third magnetic element 23 and the second magnetic element 12 actuates the locking element 22, causing it to engage with the latch 11 and thus achieving the engagement connection between the male buckle 10 and the female buckle 20. In this process, the latch 11 can easily enter the lock hole 24 without pressing the locking part 221, and the locking element 22 does not need to move through the deformation of the elastic element.

[0051] Furthermore, the locking element 22 is a rigid structure, and the third magnetic element 23 is fixedly mounted on the locking element 22. Therefore, the locking element 22 can move under the action of magnetic force. The locking part 221 moves to the locked state solely by the magnetic force between the third magnetic element 23 and the second magnetic element 12. Therefore, it can greatly simplify the structure of the locking element 22 and reduce the size of the female buckle 20, thereby facilitating structural miniaturization.

[0052] In the preset state, i.e., when the male buckle 10 and the female buckle 20 are separated and not subjected to external force, the locking part 221 can be set to extend beyond the lock hole 24 or not extend beyond the lock hole 24. Traditional safety buckles with elastic components require the locking part 221 to extend beyond the lock hole 24 in the preset state. However, when the locking element 22 is actuated by magnetic force, the default position of the locking part 221 can be flexibly set.

[0053] To describe the structure of the present invention in more detail, different embodiments are described below:

[0054] Example 1

[0055] As shown in Figures 1 and 2, the male buckle 10 is provided with a locking tongue 11 and a second magnetic element 12.

[0056] As shown in Figures 1 and 2, the latch 11 is protruding, with its end shaped like a frustum and having a first conical surface. This first conical surface facilitates the latch 11's entry into the lock hole 24. To achieve locking, a groove 111 is provided on the latch 11, which engages with the locking part 221 to achieve a locking connection. The groove 111 is located slightly away from the end face of the latch 11. The groove 111 can be annular or its shape matches the shape and size of the locking part 221. When the latch 11 enters the lock hole 24, the locking part 221 engages within the groove 111, locking the male buckle 10 and female buckle 20 together.

[0057] As shown in Figures 1 and 2, the position of the second magnetic element 12 corresponds to the position of the latch 11. In this embodiment, the second magnetic element 12 is disposed inside the latch 11.

[0058] As shown in Figures 1 and 2, the female buckle 20 includes a housing 25, a locking component 22, a first magnetic component 21, and a third magnetic component 23.

[0059] As shown in Figures 1 and 2, the housing 25 is used to house the locking element 22 and the first magnetic element 21, and its shape and structure can be configured as needed. Typically, for ease of processing and assembly, it usually includes a first housing 251 and a second housing 252 that are joined together. When the first housing 251 and the second housing 252 are joined together, an accommodating cavity is formed inside, which can be used to house the locking element 22 and the first magnetic element 21. Furthermore, to facilitate the placement of the first magnetic element 21, a magnet holder 253 can be provided inside as needed.

[0060] To facilitate the insertion of the latch 11 of the male buckle 10 into the female buckle 20, a locking hole 24 is provided on the housing 25. The shape of the locking hole 24 can be set as needed; in this embodiment, it is a circular hole.

[0061] As shown in Figures 1 and 2, the position of the first magnetic element 21 inside the female buckle 20 should be opposite to the position of the lock hole 24, so that it can be easily attracted to the second magnetic element 12 inside the lock tongue 11.

[0062] The locking element 22 is movably disposed within the housing 25. As shown in Figures 1 and 2, the locking element 22 includes a locking part 221, an unlocking part 222, and a magnet mounting part 223 that are fixedly connected or integrally formed. Furthermore, it may also include an enclosing part 224.

[0063] The locking part 221 is used to engage with the latch 11 to engage the male buckle 10 and the female buckle 20 together. The locking part 221 can be inserted into the groove 111 of the latch 11 in the second direction, so that the latch 11 engages with the locking member 22.

[0064] The unlocking part 222 is partially exposed outside the housing 25 of the female buckle 20 and can be used for unlocking operations. For example, by pressing or pulling.

[0065] The magnet mounting part 223 is provided with a magnet mounting groove 2231, which is used to mount the third magnetic component 23. The size and shape of the magnet mounting groove 2231 can be set as needed. In this embodiment, it is a rectangular groove, and the rectangular third magnetic component 23 is mounted in the magnet mounting groove 2231.

[0066] Furthermore, the enclosure portion 224 is annular, corresponding to the position of the lock hole 24, and is larger than the circumferential dimension of the lock hole 24.

[0067] The locking part 221 and the unlocking part 222 are respectively disposed on the enclosing part 224 and are spaced apart from each other. In this embodiment, the locking part 221 and the unlocking part 222 are located on the same diameter of the enclosing part 224 and are spaced apart from each other. The magnet mounting part 223 is connected to the locking part 221, and the magnet mounting part 223 is located on the side of the locking part 221 opposite to the unlocking part 222.

[0068] In other words, the locking part 221 and the magnet mounting part 223 are located on one side of the enclosure part 224, and the unlocking part 222 is located on the other side of the enclosure part 224.

[0069] The preset position of the locking part 221 is affected by the magnetic force between the third magnetic element 23 and the first magnetic element 21. It may be in the first position, the second position, or any position between the first and second positions.

[0070] When the locking tongue 11 is inserted in the locking direction, in the first stage, the third magnetic element 23 and the second magnetic element 12 repel each other, thereby keeping the locking part 221 in the first position or moving it to the first position in the first direction.

[0071] When the locking part 221 is in the first position in the preset state, in the first stage, the magnetic repulsion between the third magnetic element 23 and the second magnetic element 12 cannot actuate the locking part 22, and the locking part 22 remains in the first position.

[0072] When the locking part 221 is not in the first position in the preset state, in the first stage, the magnetic repulsion between the third magnetic element 23 and the second magnetic element 12 will actuate the locking part 22, causing the locking part 22 to move towards the first position along the first direction, thereby moving to the first position.

[0073] As the latch 11 continues to advance, the magnetic properties between the third magnetic element 23 and the second magnetic element 12 change, entering the second stage. At this time, the third magnetic element 23 and the second magnetic element 12 attract each other, thereby actuating the locking element 22 from the first position to the second position along the second direction, thus engaging with the latch 11 to achieve the engagement connection between the male buckle 10 and the female buckle 20.

[0074] When the female buckle 20 and the male buckle 10 are locked together, and unlocking is required, press the unlocking part 222. The locking part 22 moves along the first direction, thereby moving the locking part 221 to the first position and disengaging from the bolt 11. At this time, the male buckle 10 can be separated from the female buckle 20.

[0075] Example 2

[0076] The structure of the male buckle 10 in this embodiment is the same as that in embodiment 1.

[0077] The female buckle 20 includes a housing 25, a locking component 22, an unlocking component 26, a first magnetic component 21, and a second magnetic component 12.

[0078] As shown in Figures 3 and 4, the housing 25 is used to house the locking element 22, the unlocking element 26, and the first magnetic element 21, and its shape and structure can be configured as needed. Typically, for ease of processing and assembly, it usually includes a first housing 251 and a second housing 252 that are joined together. When the first housing 251 and the second housing 252 are joined together, an accommodating cavity is formed inside, which can be used to house the locking element 22, the unlocking element 26, and the first magnetic element 21. Furthermore, to facilitate the placement of the first magnetic element 21, a magnet holder 253 can be provided inside as needed.

[0079] To facilitate the insertion of the latch 11 of the male buckle 10 into the female buckle 20, a locking hole 24 is provided on the housing 25. The shape of the locking hole 24 can be set as needed; in this embodiment, it is a circular hole.

[0080] As shown in Figures 3 and 4, the position of the first magnetic element 21 inside the female buckle 20 should be opposite to the position of the lock hole 24, so that it can be easily attracted to the second magnetic element 12 inside the lock tongue 11.

[0081] The unlocking component 26 is used for unlocking operations. It is movably located in the female buckle 20 and can move along a direction perpendicular to the locking direction.

[0082] The locking component 22 includes a locking part 221 that is fixedly connected or integrally formed, a magnet mounting part 223, and a linkage part 225.

[0083] The locking part 221 can engage with the latch 11 to engage the male buckle 10 and the female buckle 20 together. The locking part 221 can be inserted into the groove 111 of the latch 11 along the second direction, thereby engaging the latch 11 with the locking member 22.

[0084] The magnet mounting part 223 is provided with a magnet mounting groove 2231, which is used to mount the third magnetic component 23. The third magnetic component 23 is mounted in the magnet mounting groove 2231 and is linked with the locking component 22.

[0085] The linkage part 225 is linked with the unlocking member 26, and can be actuated under the linkage of the unlocking member 26 to move the locking member 22 from the second position to the first position.

[0086] Furthermore, the cooperating manufacturer is perpendicular to the first direction and the second direction.

[0087] Furthermore, the unlocking component 26 includes a pressing part 261, an elastic arm 262, and a linkage post 263.

[0088] Two pressing parts 261 are provided, which are arranged at intervals relative to each other and are partially exposed in the housing 25 of the female buckle 20. The pressing parts 261 are unlocked by pressing them towards each other.

[0089] The elastic arm 262 is connected between the pressing parts 261, so that the unlocking member 26 is in the shape of a ring or two opposing semi-rings.

[0090] The linkage column 263 is disposed on the elastic arm 262 and extends along the locking direction. It is used to push the linkage part 225 to drive the locking member 22.

[0091] The number of linkage posts 263 can be set as needed. In this embodiment, the linkage posts 263 are arranged on the elastic arm 262 with the first direction as the axis of symmetry. Correspondingly, the linkage part 225 is symmetrically arranged at the end of the magnet mounting part 223 away from the locking part 221 with the first direction as the axis of symmetry.

[0092] The locking element 22 is movably placed in the housing 25 and can move along the first direction and the second direction.

[0093] The elastic arm 262 is stacked on the locking member 22, and its linkage post 263 faces the locking member 22. The linkage part 225 has an action surface 2251 facing the linkage post 263, and the action surface 2251 is set at an angle to the first direction and the cooperating direction. When the linkage post 263 moves, the linkage post 263 acts on the action surface 2251, thereby driving the locking member 22 to move along the first direction and exit the lock hole 24.

[0094] The preset position of the locking part 221 is affected by the magnetic force between the third magnetic element 23 and the first magnetic element 21. It may be in the first position, the second position, or any position between the first and second positions.

[0095] When the locking tongue 11 is inserted in the locking direction, in the first stage, the third magnetic element 23 and the second magnetic element 12 repel each other, thereby keeping the locking part 221 in the first position or moving it to the first position in the first direction.

[0096] When the locking part 221 is in the first position in the preset state, in the first stage, the magnetic repulsion between the third magnetic element 23 and the second magnetic element 12 does not cause the locking part 22 to move, and the locking part 22 remains in the first position.

[0097] When the locking part 221 is not in the first position in the preset state, in the first stage, the magnetic repulsion between the third magnetic element 23 and the second magnetic element 12 will actuate the locking part 22, causing the locking part 22 to move towards the first position along the first direction, thereby moving to the first position.

[0098] As the latch 11 continues to advance, the magnetic properties between the third magnetic element 23 and the second magnetic element 12 change, entering the second stage. At this time, the third magnetic element 23 and the second magnetic element 12 attract each other, thereby actuating the locking element 22 from the first position to the second position along the second direction, thus engaging with the latch 11 to achieve the engagement connection between the male buckle 10 and the female buckle 20.

[0099] When the female buckle 20 and the male buckle 10 are locked together, and unlocking is required, the pressing part 261 is pressed in opposite directions. The elastic arm 262 undergoes elastic deformation, which causes the position of the linkage post 263 to change. This pushes the linkage part 225, causing the locking part 22 to move as a whole along the first direction. This causes the locking part 221 to move to the first position and disengage from the bolt 11. At this time, the male buckle 10 can be separated from the female buckle 20.

[0100] Furthermore, to constrain the deformation of the elastic arm 262, a protruding limiting post 254 is provided inside the housing 25, the limiting post 254 extending in the locking direction. The middle part of the elastic arm 262 is fitted onto the limiting post 254.

[0101] Furthermore, to constrain the displacement of the locking member 22, a limiting groove 255 is provided on the housing 25, and a protruding post 226 is provided on the linkage part 225. The protruding post 226 is located in the limiting groove 255, thereby ensuring that the locking member 22 can only move within the travel range of the limiting groove 255.

[0102] 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.
