Description

Technical Field

[0001] This invention relates to the field of infant and toddler vehicles, and more particularly to a magnetic fastener. Background Technology

[0002] With the continuous development of the economy and the continuous progress of science and technology, people's lives are provided with an extremely rich variety of material consumer goods, and infant and toddler vehicles are one of these many material consumer goods.

[0003] As we all know, braided straps are indispensable in infant and toddler vehicles; and fasteners are essential for the easy assembly and disassembly of different braided straps.

[0004] Currently, fasteners used in infant and toddler vehicles include a male buckle, a female buckle that interlocks with the male buckle, a locking element for locking the male and female buckles after interlocking, and a release mechanism for releasing the locking element. However, existing fasteners have drawbacks such as slow interlocking speed between the male and female buckles and slow disengagement speed between them.

[0005] To address the slow engagement speed of existing fasteners during the mating of male and female buckles, a new magnetic fastener has been developed. This fastener incorporates two magnetically attracted structures, one inside the male buckle and the other inside the female buckle. When the male and female buckles are mated, the attraction between the two magnets accelerates the mating process. However, while this fastener speeds up the engagement, it reduces the efficiency of the release mechanism.

[0006] To address the slow release efficiency of existing fasteners, a new type of magnetic fastener on the market features a two-magnet structure with mutual magnetic repulsion. One magnet is installed inside the male fastener, and the other inside the female fastener. When the release mechanism is pressed, the male and female fasteners quickly separate due to the mutual repulsion of the two magnets, achieving rapid release. However, this type of fastener significantly reduces the engagement speed of the male and female fasteners.

[0007] Therefore, there is an urgent need for a magnetic fastener to overcome the above-mentioned defects. Summary of the Invention

The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention.

[0163] Please see Figures 1 to 8 , Figure 1 This is a schematic diagram of the magnetic buckle 100a of the first embodiment of the present invention, viewed from the front. Figure 2 This is a three-dimensional structural diagram of the magnetic buckle 100a of the first embodiment of the present invention after the second fastener 3 cover is removed. Figure 3 This is a schematic diagram of the internal structure of the magnetic buckle 100a according to the first embodiment of the present invention. Figure 4 This is a partial structural schematic diagram of the magnetic buckle 100a according to the first embodiment of the present invention. Figure 5 This is the first embodiment of the present invention. Figure 4 Enlarged schematic diagram of point F of the magnetic fastener 100a. Figure 6 This is a partial structural schematic diagram of the magnetic buckle 100a according to the first embodiment of the present invention from another perspective. Figure 7 and Figure 8 This is a schematic diagram of the first magnetic structure 7 and the second magnetic structure 8 in different states according to the first embodiment of the present invention. Figures 1 to 6 As shown, the magnetic buckle 100a of the first embodiment includes two first fasteners 10, a second fastener 3, two locking members 6, a moving member 5, two first magnetic structures 7, an unlocking operation part 4, and a second magnetic structure 8.

[0164] The second fastener 3 is used to engage with the first fastener 10. The moving part 5 is pivotally connected to the second fastener 3 around the pivot center line L and is linked to the release operation part 4. The second magnetic structure 8 is disposed on the moving part 5. Each first magnetic structure 7 is mounted on the corresponding first fastener 10 and is used to selectively magnetically attract or magnetically repel the second magnetic structure 8. Each locking part 6 is movably disposed on the second fastener 3 and is linked to the release operation part 4. Each locking part 6 is used to engage the corresponding first fastener 10 after the first fastener 10 and the second fastener 3 are engaged, so as to lock the first fastener 10 and the second fastener 3 after engagement, thereby preventing the first fastener 10 and the second fastener 3 from separating. The release operation part 4 is movably disposed on the second fastener 3 and is used to drive the two locking parts 6 to release. In detail, during the process of driving the locking parts 6 to release, the release operation part 4 drives the moving part 5 to rotate around the pivot center line L to reverse the magnetic field direction of the second magnetic structure 8 on the moving part 5.

[0165] Specifically, two first fasteners 10 are arranged opposite each other with the pivot center line L as the center, and each first fastener 10 may include a shoulder strap buckle 1 and a waist belt buckle 2. Each shoulder strap buckle 1 and the corresponding waist belt buckle 2 are combined to form a male buckle. The second fastener 3 may be a crotch buckle, wherein the crotch buckle is a female buckle used to mate with the male buckle formed by the shoulder strap buckle 1 and the waist belt buckle 2 along the side direction of the magnetic buckle 100a. The movable member 5 is set on the second fastener 3 (i.e., the crotch buckle) in a manner that can rotate around the pivot center line L. Each locking member 6 and the unlocking operation part 4 are movably set on the second fastener 3 (i.e., the crotch buckle) and are linked to each other. Two first magnetic structures 7 are respectively embedded in the two waist belt buckles 2 and are arranged opposite each other with the pivot center line L as the center. The second magnetic structure 8 can magnetically attract or magnetically repel the two first magnetic structures 7 to assist in the insertion or separation of the male buckle and female buckle (i.e., the crotch buckle) formed by the shoulder strap buckle 1 and the waist belt buckle 2 (i.e., the insertion and separation of the first fastener 10 and the second fastener 3).

[0166] However, the present invention is not limited to this embodiment. For example, in another embodiment, each shoulder strap buckle can form an integral male buckle with the corresponding waist belt buckle, and two first magnetic structures can be respectively embedded in the two male buckles.

[0167] Alternatively, in another embodiment, the crotch buckle can be a male buckle, and the two shoulder buckles and the two waist buckles can together form a female buckle with an integral structure. That is, this embodiment has only one first buckle and one second buckle. Furthermore, the movable member can be rotatably disposed on the female buckle, and the unlocking operation part and the locking member can be movably disposed on the female buckle. In addition, this embodiment may have only one first magnetic structure embedded in the crotch buckle and one second magnetic structure embedded in the movable member for magnetic attraction or magnetic repulsion with the first magnetic structure.

[0168] Preferably, in this embodiment, the two first magnetic structures 7 and the second magnetic structure 8 can be permanent magnets, but the present invention is not limited thereto. For example, in another embodiment, the first magnetic structure or the second magnetic structure can be an electromagnet.

[0169] Please see Figure 2 , Figure 3 and Figure 6 The magnetic buckle 100a of the first embodiment further includes two third magnetic structures 9. Each third magnetic structure 9 is embedded in a corresponding shoulder strap buckle 1 and is used to magnetically attract the corresponding first magnetic structure 7 embedded in the corresponding waist belt buckle 2, thereby strengthening the connection between the corresponding shoulder strap buckle 1 and the corresponding waist belt buckle 2, making the connection between the two more secure. Preferably, in this embodiment, the third magnetic structure 9 can be a permanent magnet. Of course, in other embodiments, the third magnetic structure can be replaced by a magnetic attraction structure, which can attract the first magnetic structure 7. Specifically, the magnetic attraction structure is a ferromagnetic structure, which can be made of a magnetically conductive material, such as iron, cobalt, nickel, gadolinium, and their alloys. Alternatively, in another embodiment, the magnetic buckle may include only one third magnetic structure.

[0170] Furthermore, preferably, in this embodiment, when each first magnetic structure 7 is assembled with the corresponding shoulder strap buckle 1 onto the corresponding waist belt buckle 2, it is aligned with the corresponding third magnetic structure 9 along the side direction of the magnetic buckle 100a, thereby making the magnetic force between the shoulder strap buckle 1 and the waist belt buckle 2 more obvious and ensuring the connection between the corresponding shoulder strap buckle 1 and the corresponding waist belt buckle 2, but this is not a limitation. For example, in another embodiment, each first magnetic structure may be aligned with the corresponding third magnetic structure along the front and back directions of the magnetic buckle when the corresponding shoulder strap buckle is assembled with the corresponding waist belt buckle.

[0171] Please refer to 3. Figure 4 and Figure 6 Each shoulder strap buckle 1 is stacked on the corresponding waist belt buckle 2 in the opposite direction of the magnetic buckle 100a. Preferably, when each shoulder strap buckle 1 is stacked on the corresponding waist belt buckle 2 in the opposite direction of the magnetic buckle 100a, each shoulder strap buckle 1 and the corresponding waist belt buckle 2 are flush with each other in the lateral direction of the magnetic buckle 100a, thereby making the assembled first buckle 10 smoother, saving space, and making it easier for the first buckle 10 to be inserted with the second buckle 3. Specifically, the waist belt buckle 2 includes a locking part 21, and each shoulder strap buckle 1 includes an extension arm 102 that matches the contour of the locking part 21. Each extension arm 102 is embedded in the corresponding locking part 21, thereby achieving that each shoulder strap buckle 1 and the corresponding waist belt buckle 2 are flush with each other in the lateral direction. Preferably, in this embodiment, the locking part 21 may be a groove formed on the back of the waist belt buckle 2, but the present invention is not limited to this.

[0172] Please see Figures 2 to 3 Each of the first magnetic structures 7 can attract each other to the second magnetic structure 8 during the insertion of the first fastener 10 and the second fastener 3. Therefore, after operating the release operation part 4, the release operation part 4 drives the moving part 5 to rotate, thereby reversing the magnetic pole position of the second magnetic structure 8 and reversing the magnetic field direction of the second magnetic structure 8. This causes each of the first magnetic structures 7 and the second magnetic structure 8 after the magnetic field direction is reversed to repel each other. Since the release operation part 4 drives the locking part 6 to perform the release movement, when the first fastener 10 and the second fastener 3 are released, the magnetic repulsion force between each of the first magnetic structures 7 and the second magnetic structure 8 causes the first fastener 10 and the second fastener 3 to separate quickly, thereby achieving the purpose of fast fastening speed and fast release speed.

[0173] like Figure 7 and Figure 8 As shown, specifically, in this embodiment, the first end 71 and the second end 72 of the first magnetic structure 7 on the left can be the south pole (S) and the north pole (N) respectively, the first end 73 and the second end 74 of the first magnetic structure 7 on the right can be the south pole (S) and the north pole (N) respectively, and the first end 81 and the second end 82 of the second magnetic structure 8 can be the south pole (S) and the north pole (N) respectively. When the release operation unit 4 is released, the two first magnetic structures 7 and the second magnetic structure 8 are located as follows: Figure 7 The positions are shown so that the first end 81 and the second end 82 of the second magnetic structure 8 can magnetically attract the second end 72 of the first magnetic structure located on the left and the first end 73 of the first magnetic structure located on the right, respectively. When the release operation part 4 is operated and slides, the second magnetic structure 8 is driven to rotate 180 degrees around the pivot center line L and is positioned as shown. Figure 8 The positions shown are such that the two magnetic poles of the second magnetic structure 8 are interchanged, i.e., the direction of the magnetic field of the second magnetic structure 8 is reversed. At this time, the first end 81 and the second end 82 of the second magnetic structure 8 can magnetically repel the first end 73 of the first magnetic structure on the right and the second end 72 of the first magnetic structure on the left, respectively. In detail, during the rotation of the second magnetic structure 8, the magnetic attraction force of the second magnetic structure 8 on the two first magnetic structures 7 gradually decreases, while the magnetic repulsion force of the second magnetic structure 8 on the two first magnetic structures 7 gradually increases. When the second magnetic structure 8 or the moving part 5 rotates more than 90 degrees around the pivot center line L, the resultant force of the magnetic force of the second magnetic structure 8 on the two first magnetic structures 7 changes from magnetic attraction to magnetic repulsion.

[0174] The arrangement of the first and second magnetic structures in this invention is not limited to this embodiment. In other embodiments, the first and second magnetic structures can magnetically repel each other during insertion. Therefore, after operating the release mechanism, the release mechanism rotates the moving member, causing the magnetic poles of the second magnetic structures to be reversed (orientation reversed). This allows the first and second magnetic structures to magnetically attract each other, which is suitable for preventing accidental separation. When the second magnetic structure or the moving member rotates more than 90 degrees, the resultant force of the magnetic forces acting on the two first magnetic structures changes from magnetic attraction to magnetic repulsion.

[0175] Please see Figures 2 to 6 The release operation part 4 is movably connected to the moving part 5. Specifically, the release operation part 4 is slidably disposed on the second fastener 3, and during the sliding process relative to the second fastener 3, the release operation part 4 drives the moving part 5 to rotate around the pivot center line L. Preferably, in this embodiment, the sliding direction of the release operation part 4 can be parallel to the side direction of the magnetic fastener 100a, and the arrangement direction of the pivot center line L is perpendicular to the side direction and the front and back directions of the magnetic fastener 100a. Preferably, in this embodiment, the release operation part 4 can be a button slidably disposed on the side wall of the second fastener 3 to reduce the visibility of the release operation part 4, thereby preventing infants and young children from accidentally touching it and improving the safety of the magnetic fastener 100a in the first embodiment.

[0176] Specifically, the release operation unit 4 is provided with a linkage structure 10a, and the moving member 5 is provided with a matching structure 11a that is linked to the linkage structure 10a. The release operation unit 4 drives the moving member 5 to pivot around the pivot center line L through the cooperation of the linkage structure 10a and the matching structure 11a. Preferably, in this embodiment, the linkage structure 10a is a rack arranged along the sliding direction of the release operation unit 4, and the matching structure 11a is a gear that meshes with the rack. The pivot center line L coincides with the center line of the gear, and the gear is located at the end of the moving member 5. Therefore, after operating the release operation unit 4, the sliding of the release operation unit 4 drives the rack to slide, thereby causing the gear meshing with it to rotate around the pivot center line L, thereby driving the moving member 5 to rotate, thereby causing the second magnetic structure 8 to adjust the position of the magnetic poles to change the direction of the magnetic force of the second magnetic structure 8 acting on the first magnetic structure 7.

[0177] Please see Figure 2 , Figure 3 as well as Figure 6The movable component 5 includes a hollow structure 53, and the second magnetic structure 8 is embedded in the hollow structure 53. Similarly, each first fastener 10 is provided with an embedding cavity 101 for embedding the first magnetic structure 7. Specifically, each embedding cavity 101 is opened on the belt buckle 2, and each embedding cavity 101 is aligned with the hollow structure 53 along the insertion direction of the first fastener 10 and the second fastener 3. Therefore, the magnetic force between the first magnetic structure 7 and the second magnetic structure 8 is more obvious during the insertion or separation process of the first fastener 10 and the second fastener 3, making the fastening speed and the release speed of the first fastener 10 and the second fastener 3 faster.

[0178] Please see Figure 2 , Figure 3 as well as Figure 6 The magnetic fastener 100a of the first embodiment further includes a first elastic member 13a for resetting the release operation part 4. Specifically, the first elastic member 13a is disposed between the release operation part 4 and the second fastener 3. Preferably, in this embodiment, the first elastic member 13a is a spring, but it is not limited thereto. Specifically, the release operation part 4 is provided with a guide part 42 for the elastic deformation of the first elastic member 13a. The first elastic member 13a is sleeved on the guide part 42, thereby making the elastic deformation and elastic recovery process of the first elastic member 13a more stable, thereby accelerating the reset speed of the release operation part 4.

[0179] Please see Figures 3 to 6 The locking member 6 includes a locking structure 61, and each first fastener 10 includes a locking structure 103 that cooperates with the locking structure 61. Each locking member 6 is slidably arranged, so the locking structure 61 slidably engages or disengages from the locking structure 103. Specifically, each locking structure 103 is formed on a corresponding belt buckle 2; however, in other embodiments, each locking structure is formed on a corresponding shoulder strap buckle, and is not limited thereto. Furthermore, in another embodiment, the locking member may also include only one locking structure.

[0180] Specifically, each locking member 6 also includes a linkage structure 151, and the release operation unit 4 includes two release linkage structures 141 that are linked to the linkage structure 151. The release operation unit 4 drives each locking structure 61 to release from its corresponding locking structure 103 through the cooperation of each release linkage structure 141 with the corresponding linkage structure 151. Preferably, in this embodiment, the release linkage structure 141 on the release operation unit 4 is a first inclined surface that is inclined relative to the sliding direction of the locking member 6, and the linkage structure 151 is a second inclined surface. Therefore, after operating the release operation unit 4, the sliding of the release operation unit 4 causes the two first inclined surfaces to slide, and the two first inclined surfaces 141 slide and cooperate with the two second inclined surfaces to push against the two second inclined surfaces, thereby causing the two locking members 6 to slide, thereby driving the two locking structures 61 to disengage from the two locking structures 103. However, the present invention is not limited to this. For example, in another embodiment, if the magnetic buckle has only one locking member and the locking member has only one linkage structure, the release operation part may only have one release linkage structure.

[0181] Please see Figures 3 to 6 The magnetic buckle 100a of the first embodiment further includes two second elastic elements 16 for resetting the two locking members 6. Specifically, each second elastic element 16 is disposed between the corresponding locking member 6 and the second buckle 3, and each second elastic element 16 always has a tendency to drive the corresponding locking structure 61 to lock with the corresponding matching locking structure 103. Preferably, in this embodiment, the second elastic element 16 may be a spring, but the invention is not limited thereto. For example, in another embodiment, the magnetic buckle may also have only one locking member and one second elastic element.

[0182] In addition, each locking member 6 is provided with a guide structure 62 for the corresponding second elastic member 16 to undergo elastic deformation. Each second elastic member 16 is sleeved on the corresponding guide structure 62, so that the elastic deformation and elastic recovery process of each second elastic member 16 is stable.

[0183] Please see Figures 9 to 22 , Figure 9 This is a schematic diagram of the magnetic buckle 100b according to the second embodiment of the present invention, viewed from the front. Figure 10 The magnetic buckle 100b of the second embodiment of the present invention is along Figure 9 A cross-sectional view after being cut along the CC section line. Figure 11 The magnetic buckle 100b of the second embodiment of the present invention is along Figure 9 A cross-sectional view after cutting along the DD section line. Figures 12 to 14 This is a schematic diagram of the first magnetic structure 7 and the second magnetic structure 8 in different states according to the second embodiment of the present invention. Figure 15 This is a schematic diagram of the magnetic fastener 100b according to the second embodiment of the present invention when the first fastener 10 and the second fastener 3 are separated. Figure 16 and Figure 17 This is a three-dimensional structural diagram of the first fastener 10 in the second embodiment of the present invention from different perspectives. Figure 18 This is an exploded view of the first fastener 10 according to the second embodiment of the present invention. Figure 19 and Figure 20 This is a partial structural schematic diagram of the magnetic buckle 100b according to the second embodiment of the present invention. Figure 21 This is a three-dimensional structural schematic diagram of another part of the magnetic buckle 100b according to the second embodiment of the present invention. Figure 22 This is a partially exploded view of the magnetic buckle 100b according to the second embodiment of the present invention. The magnetic buckle 100b of the second embodiment has a substantially the same structure as the magnetic buckle 100a of the first embodiment, the difference being:

[0184] First, such as Figure 10 and Figures 11 to 14 As shown, in this embodiment, the pivot center line L is arranged along the positive and negative directions of the magnetic buckle 100b. In contrast, in the first embodiment, the pivot center line L of the magnetic buckle 100a is arranged along the side direction of the magnetic buckle 100a.

[0185] like Figure 12 and Figure 14 As shown, specifically, in this embodiment, the first end 71 and the second end 72 of the first magnetic structure 7 on the left can be the south pole (S) and the north pole (N) respectively, the first end 73 and the second end 74 of the first magnetic structure 7 on the right can be the south pole (S) and the north pole (N) respectively, and the first end 81 and the second end 82 of the second magnetic structure 8 can be the south pole (S) and the north pole (N) respectively. When the release operation unit 4 is released, the two first magnetic structures 7 and the second magnetic structure 8 are located as follows: Figure 12 The positions are shown so that the first end 81 and the second end 82 of the second magnetic structure 8 can magnetically attract the second end 72 of the first magnetic structure located on the left and the first end 73 of the first magnetic structure located on the right, respectively. When the release operation part 4 is operated and slides, the second magnetic structure 8 is driven to rotate 180 degrees around the pivot center line L and is positioned as shown. Figure 14 The positions shown are such that the two magnetic poles of the second magnetic structure 8 are interchanged, that is, the direction of the magnetic field of the second magnetic structure 8 is reversed. At this time, the first end 81 and the second end 82 of the second magnetic structure 8 can magnetically repel the first end 73 of the first magnetic structure located on the right and the second end 72 of the first magnetic structure located on the left, respectively. In detail, the second magnetic structure 8 is composed of... Figure 12 Rotate to the position shown as Figure 14During the process shown, the magnetic attraction of the second magnetic structure 8 to the two first magnetic structures 7 gradually decreases, while the magnetic repulsion of the second magnetic structure 8 to the two first magnetic structures 7 gradually increases. When the second magnetic structure 8 or the moving part 5 rotates more than 90 degrees around the pivot center line L (i.e., the second magnetic structure 8 crosses the pivot line L), the magnetic attraction of the second magnetic structure 8 to the two first magnetic structures 7 gradually decreases, while the magnetic repulsion of the second magnetic structure 8 to the two first magnetic structures 7 gradually increases. Figure 13 When the position shown is reached, the resultant force of the magnetic forces exerted by the second magnetic structure 8 on the two first magnetic structures 7 changes from a magnetic attraction force to a magnetic repulsion force. However, this invention is not limited to this specific force; please refer to [reference needed]. Figures 23 to 25 , Figures 23 to 25 This is a schematic diagram of the first magnetic structure 7 and the second magnetic structure 8 in different states according to another embodiment of the present invention. Figures 23 to 25 As shown, specifically, in this embodiment, the first end 71 and the second end 72 of the first magnetic structure 7 on the left can be the south pole (S) and the north pole (N) respectively, and the first end 73 and the second end 74 of the first magnetic structure 7 on the right can be the north pole (N) and the south pole (S) respectively. The second magnetic structure 8 can have two opposing attraction parts 83 and two opposing repulsion parts 84. The line segment connecting the two attraction parts 83 is perpendicular to the line segment connecting the two repulsion parts 84. The two attraction parts 83 and the two repulsion parts 84 can be the two south poles (S) and the two north poles (N) respectively. When the release operation part 4 is released, the two first magnetic structures 7 and the second magnetic structure 8 are located as follows: Figure 23 The positions are shown so that the two attracting portions 83 of the second magnetic structure 8 located at the three o'clock and nine o'clock positions can magnetically attract the second end 72 of the first magnetic structure located on the left and the first end 73 of the first magnetic structure located on the right, respectively. When the release operation part 4 is operated and slides, the second magnetic structure 8 is driven to rotate 90 degrees around the pivot center line L and is positioned as shown. Figure 25 The positions shown are such that the direction of the magnetic force exerted by the second magnetic structure 8 on the two first magnetic structures changes. At this time, the two repulsive portions 84 of the second magnetic structure 8 can magnetically repel the first end 73 of the first magnetic structure on the right and the second end 72 of the first magnetic structure on the left, respectively. Specifically, the second magnetic structure 8 is composed of... Figure 23 Rotate to the position shown as Figure 25 During the process shown, the magnetic attraction of the second magnetic structure 8 to the two first magnetic structures 7 gradually decreases, while the magnetic repulsion of the second magnetic structure 8 to the two first magnetic structures 7 gradually increases. When the second magnetic structure 8 or the moving part 5 rotates more than 45 degrees around the pivot center line L (i.e., the second magnetic structure 8 crosses the...), the magnetic attraction of the second magnetic structure 8 to the two first magnetic structures 7 gradually decreases, while the magnetic repulsion of the second magnetic structure 8 to the two first magnetic structures 7 gradually increases. Figure 24 When the position shown is reached, the resultant force of the magnetic forces exerted by the second magnetic structure 8 on the two first magnetic structures 7 changes from magnetic attraction to magnetic repulsion.

[0186] Please refer to the following: Figures 26 to 28 , Figures 26 to 28 This is a schematic diagram of the first magnetic structure 7 and the second magnetic structure 8 in different states according to another embodiment of the present invention. Figures 26 to 28 As shown, specifically, in this embodiment, the first end 71 and the second end 72 of the first magnetic structure 7 on the left can be the south pole (S) and the north pole (N) respectively, and the first end 73 and the second end 74 of the first magnetic structure 7 on the right can be the south pole (S) and the north pole (N) respectively. The second magnetic structure 8 can have two opposing attraction parts 83 and two opposing repulsion parts 84. The line segment connecting the two attraction parts 83 is perpendicular to the line segment connecting the two repulsion parts 84. The two attraction parts 83 can be made of magnetically conductive material, and the two repulsion parts 84 can be the north pole (N) and the south pole (S) respectively. When the release operation part 4 is released, the two first magnetic structures 7 and the second magnetic structure 8 are located as follows: Figure 26 The positions are shown so that the two attracting portions 83 of the second magnetic structure 8 located at the three o'clock and nine o'clock positions can magnetically attract the second end 72 of the first magnetic structure located on the left and the first end 73 of the first magnetic structure located on the right, respectively. When the release operation part 4 is operated and slides, the second magnetic structure 8 is driven to rotate 90 degrees around the pivot center line L and is positioned as shown. Figure 28 The positions shown are such that the direction of the magnetic force exerted by the second magnetic structure 8 on the two first magnetic structures changes. At this time, the two repulsive portions 84 of the second magnetic structure 8 can magnetically repel the first end 73 of the first magnetic structure on the right and the second end 72 of the first magnetic structure on the left, respectively. Specifically, the second magnetic structure 8 is composed of... Figure 26 Rotate to the position shown as Figure 28 During the process shown, the magnetic attraction of the second magnetic structure 8 to the two first magnetic structures 7 gradually decreases, while the magnetic repulsion of the second magnetic structure 8 to the two first magnetic structures 7 gradually increases. When the second magnetic structure 8 or the moving part 5 rotates more than 45 degrees around the pivot center line L (i.e., the second magnetic structure 8 crosses the...), the magnetic attraction of the second magnetic structure 8 to the two first magnetic structures 7 gradually decreases, while the magnetic repulsion of the second magnetic structure 8 to the two first magnetic structures 7 gradually increases. Figure 27 When the position shown is reached, the resultant force of the magnetic forces exerted by the second magnetic structure 8 on the two first magnetic structures 7 changes from magnetic attraction to magnetic repulsion.

[0187] Second, such as Figures 9 to 11 and Figure 15 As shown, in this embodiment, the release operation part 4 is rotatably provided on the front of the second fastener 3 and can be a knob. In contrast, the release operation part 4 of the magnetic fastener 100a in the first embodiment is slidably provided on the side wall of the second fastener 3 and can be a button.

[0188] Third, such as Figures 9 to 11 and Figure 21As shown, in this embodiment, the release operation part 4 is fixedly connected to the moving part 5. Rotating the release operation part 4 causes the moving part 5 to pivot about the pivot center line L. The release operation part 4 includes a connecting cavity 41, which includes a connecting cavity opening facing the moving part 5. The second magnetic structure 8 is partially located within the connecting cavity 41, and the end of the moving part 5 blocks the connecting cavity opening. The magnetic fastener 100b of the second embodiment also includes a connector 12 that fixes the release operation part 4 and the moving part 5 together along the pivot center line L. Preferably, in this embodiment, the connector 12 is a threaded part. Of course, in other embodiments, the connector can also be a rivet or a pin, but is not limited thereto. The end of the moving part 5 includes a receiving cavity 52 that communicates with the connecting cavity 41. The receiving cavity 52 includes a receiving cavity opening facing the connecting cavity 41, and the second magnetic structure 8 is located in both the connecting cavity 41 and the receiving cavity 52. In the magnetic buckle 100a of the first embodiment, the sliding of the release operation part 4 causes the moving part 5 to rotate, and the second magnetic structure 8 is embedded in the hollow structure 53 of the moving part 5.

[0189] Fourth, such as Figure 10 , Figure 11 , Figure 20 and Figure 22 As shown, in this embodiment, the first elastic element 13b is disposed between the movable element 5 and the second fastener 3. The first elastic element 13b always has a tendency to drive the movable element 5 to reset the release operation part 4. Preferably, in this embodiment, the first elastic element 13b can be a torsion spring sleeved on the movable element 5 and located between the movable element 5 and the locking element 6. In the magnetic fastener 100a of the first embodiment, the first elastic element 13a is a spring and is located between the release operation part 4 and the second fastener 3.

[0190] Fifth, such as Figure 10 , Figure 11 and Figures 16 to 19 As shown, in this embodiment, the locking structure 103 is formed on the shoulder strap buckle 1, while in the magnetic buckle 100a of the first embodiment, the locking structure 103 is formed on the waist belt buckle 2.

[0191] Sixth, such as Figures 10 to 11 and Figures 21 to 22As shown, in this embodiment, the locking member 6 and the moving member 5 are linked. During the unlocking process, the unlocking operation unit 4 drives the moving member 5 to rotate around the pivot center line L to reverse the magnetic direction of the second magnetic structure 8 on the moving member 5. At the same time, the unlocking operation unit 4 indirectly drives the locking member 6 to perform unlocking movement through the moving member 5. Specifically, the locking member 6 also includes a linkage structure 152, and the moving member 5 includes an unlocking linkage structure 142 that is linked to the linkage structure 152. More specifically, the unlocking linkage structure 142 is located at the end of the moving member 5 facing the locking member 6. The moving member 5 drives the locking structure 61 and the matching locking structure 103 to unlock through the cooperation of the unlocking linkage structure 142 and the linkage structure 152. Preferably, the unlocking linkage structure 142 on the moving member 5 can be a first helical inclined surface, the helical center line of the first helical inclined surface coincides with the pivot center line L, and the linkage structure 152 is a matching second helical inclined surface. The rotation of the moving member 5 causes the first helical inclined surface to rotate, thereby pushing against the matching second helical inclined surface, which in turn pushes the locking member 6 to slide, thus disengaging the locking structure 61 from the locking structure 103. Of course, in other embodiments, the linkage structure can be the first helical inclined surface whose helical center line coincides with the pivot center line, and the release linkage structure can be a protrusion sliding along the first helical inclined surface; or, the release linkage structure can be the first helical inclined surface whose helical center line coincides with the pivot center line, and the linkage structure can be a protrusion sliding along the first helical inclined surface. By using the first helical inclined surface to push against the protrusion or by the protrusion pushing against the first helical inclined surface, the purpose of the moving member pushing against the locking member can also be achieved, so it is not limited to this. In the magnetic buckle 100a of the first embodiment, the locking member 6 is linked to the release operation part 4. The release linkage structure 141 (i.e., the first inclined surface) of the release operation unit 4 and the linkage cooperation structure 151 (i.e., the second inclined surface) of the locking member 6 push and cooperate to disengage the locking structure 61 from the locking structure 103.

[0192] Seventh, such as Figure 10 and Figure 11 As shown, in this embodiment, the first magnetic structure 7 is opposite to the third magnetic structure 9 along the front and back directions of the magnetic buckle 100b. However, in the magnetic buckle 100a of the first embodiment, the first magnetic structure 7 is opposite to the third magnetic structure 9 along the side direction of the magnetic buckle 100b.

[0193] Apart from the differences mentioned above, the other structures of the magnetic buckle 100b in the second embodiment are roughly the same as those of the magnetic buckle 100a in the first embodiment, and therefore will not be described in detail here.

[0194] Please see Figure 29 and Figure 39 , Figure 29 This is a schematic diagram of the magnetic buckle 100c according to the third embodiment of the present invention, viewed from the front. Figure 30The magnetic buckle 100c of the third embodiment of the present invention is along Figure 29 The sectional view after cutting along the EE section line. Figure 31 The magnetic buckle 100c of the third embodiment of the present invention is along Figure 29 A sectional view after cutting along the FF section line. Figure 32 The magnetic buckle 100c of the third embodiment of the present invention is along Figure 29 A sectional view after cutting along the GG section line. Figure 33 and Figure 34 This is a schematic diagram of the magnetic fastener 100c of the third embodiment of the present invention when the first fastener 10 is removed, taken from different angles. Figure 35 This is a schematic diagram of the magnetic buckle 100c according to the third embodiment of the present invention when the cover of the first fastener 10 and the second fastener 3 are removed. Figure 36 This is an exploded view of the magnetic buckle 100c according to the third embodiment of the present invention. Figure 37 This is a partial structural schematic diagram of the magnetic buckle 100c according to the third embodiment of the present invention. Figure 38 This is another structural schematic diagram of the magnetic buckle 100c according to the third embodiment of the present invention. Figure 39 This is the third embodiment of the present invention. Figure 38 An enlarged schematic diagram of point H in the magnetic fastener 100c. The magnetic fastener 100c of the third embodiment has a structure that is largely the same as that of the magnetic fastener 100b of the second embodiment, with the following specific differences:

[0195] First, such as Figures 29 to 39As shown, in this embodiment, the release operation part 4 is movably connected to the moving part 5. Specifically, the release operation part 4 is slidably disposed on the front side of the second fastener 3, and during the sliding process relative to the second fastener 3, the release operation part 4 drives the moving part 5 to rotate around the pivot center line L. Preferably, the release operation part 4 can be a button. The sliding direction of the release operation part 4 relative to the second fastener 3 intersects with the arrangement direction of the pivot center line L and is perpendicular to the side direction and the front and back directions of the magnetic fastener 100c. The release operation part 4 is provided with a linkage structure 10b, and the moving part 5 is provided with a matching structure 11b that is linked to the linkage structure 10b. The release operation part 4 drives the moving part 5 to pivot around the pivot center line L through the cooperation of the linkage structure 10b and the matching structure 11b. Preferably, in this embodiment, the linkage structure 10b is a linkage slot, and the coupling structure 11b is a linkage column placed within the linkage slot and sliding within the linkage slot. The linkage column is offset relative to the pivot center line L. Therefore, when the sliding linkage of the release operation part 4 slides, the linkage slot pushes the linkage column to slide within the linkage slot. Since the linkage column is offset relative to the pivot center line L, the moving member 5 rotates. More specifically, the linkage post is located at the end face of the movable member 5 facing the release operation part 4, and the length direction of the linkage groove intersects with the sliding direction of the release operation part 4 relative to the second fastener 3. Preferably, the length direction of the linkage groove is perpendicular to the sliding direction of the release operation part 4 relative to the second fastener 3. Therefore, the linkage post is subjected to both the sliding force of the release operation part 4 and the driving force of the linkage groove in the length direction. Thus, the combined force of the two forces drives the linkage post to rotate around the pivot center line. In addition, the middle part of the movable member 5 includes a hollow structure 53, and the second magnetic structure 8 is embedded in the hollow structure 53. In the magnetic fastener 100b of the second embodiment, the release operation part 4 is fixedly connected to the movable member 5. The release operation part 4 is a knob. Rotating the release operation part 4 drives the rotation of the movable member 5. The second magnetic structure 8 is located in the connecting cavity 41 and the receiving cavity 52.

[0196] Second, such as Figure 32 and Figures 35 to 37 As shown, in this embodiment, the first elastic element 13a can be a spring and is located between the release operation part 4 and the second fastener 3. The release operation part 4 is provided with a guide part 42 for the elastic deformation of the first elastic element 13a, and the first elastic element 13a is sleeved on the guide part 42. In the second embodiment 100b, the first elastic element 13b is a torsion spring sleeved on the moving part 5 and located between the moving part 5 and the second fastener 3, that is, the side of the moving part 5 provides a guiding function for the elastic deformation of the torsion spring 13b.

[0197] Apart from the differences mentioned above, the other structures of the magnetic buckle 100c in the third embodiment are roughly the same as those of the magnetic buckle 100b in the second embodiment, and therefore will not be described in detail here.

[0198] Please see Figures 40 to 49 , Figure 40 This is a schematic diagram of the magnetic buckle 100d according to the fourth embodiment of the present invention, viewed from the front. Figure 41 and Figure 42 This is a partial schematic diagram of the magnetic buckle 100d according to the fourth embodiment of the present invention from different viewing angles.

Figure 48 This is a three-dimensional structural diagram of the second fastener 3 according to the fourth embodiment of the present invention. Figure 49 This is an exploded view of the second fastener 3 according to the fourth embodiment of the present invention. The magnetic fastener 100d of the fourth embodiment has a generally similar structure to the magnetic fastener 100c of the third embodiment, with the following specific differences:

[0199] like Figures 40 to 49 As shown, in this embodiment, the linkage structure 10a is a rack arranged along the sliding direction of the release operation part 4, and the matching structure 11a is a gear meshing with the rack. The sliding of the release operation part 4 causes the rack to slide, thereby causing the gear meshing with the rack to rotate, which in turn drives the moving member 5 to rotate about the pivot center line L. Specifically, the gear is located at the end of the moving member 5 facing the release operation part 4. In the magnetic fastener 100c of the third embodiment, the linkage structure 10b is a linkage slot, and the matching structure 11b is a linkage post. Furthermore, in this embodiment, the release operation part 4 includes a release linkage structure 141 (i.e., a first inclined surface), and the locking member 6 includes a linkage engagement structure 151 (i.e., a second inclined surface), so that when the release operation part 4 is operated and slides, the release operation part 4 can drive the locking member 6 through the engagement of the release linkage structure 141 and the linkage engagement structure 151.

[0200] Apart from the differences mentioned above, the other structures of the magnetic buckle 100d in the fourth embodiment are roughly the same as those of the magnetic buckle 100c in the third embodiment, and therefore will not be described in detail here.

[0201] Please see Figures 50 to 55 , Figure 50 This is a schematic diagram of the structure of the magnetic buckle 100e according to the fifth embodiment of the present invention. Figure 51This is a schematic diagram of the magnetic buckle 100e of the fifth embodiment of the present invention when the two first fasteners 10 are removed. Figure 52 This is a partial structural schematic diagram of the magnetic buckle 100e according to the fifth embodiment of the present invention. Figure 53 This is a partial exploded view of the magnetic buckle 100e according to the fifth embodiment of the present invention. Figure 54 This is another structural schematic diagram of the magnetic buckle 100e according to the fifth embodiment of the present invention. Figure 55 This is a schematic diagram of the locking member 6 according to the fifth embodiment of the present invention. The magnetic buckle 100e of the fifth embodiment has a structure that is generally the same as that of the magnetic buckle 100a of the first embodiment, with the following specific differences:

[0202] First, such as Figures 50 to 55 As shown, in this embodiment, the release operation part 4 is slidably disposed on the front side of the second fastener 3, and the release operation part 4 slides along the positive and negative directions of the magnetic fastener 100e. In the magnetic fastener 100a of the first embodiment, the release operation part 4 is slidably disposed on the side wall of the second fastener 3, and the release operation part 4 slides along the side direction of the magnetic fastener 100a.

[0203] Second, such as Figures 53 to 55 As shown, the release linkage structure 141 (i.e., the first inclined surface) is formed on the side wall of the release operation part 4, and the linkage engagement structure 151 (i.e., the second inclined surface) is formed on the protrusion 63 on the side wall of the locking member 6. In the magnetic buckle 100a of the first embodiment, the release linkage structure 141 (i.e., the first inclined surface) is formed on the bottom wall of the release operation part 4, and the linkage engagement structure 151 (i.e., the second inclined surface) is formed on the top wall of the locking member 6.

[0204] Apart from the differences mentioned above, the other structures of the magnetic buckle 100e in the fifth embodiment are roughly the same as those of the magnetic buckle 100a in the first embodiment, and therefore will not be described in detail here.

[0205] Please see Figures 56 to 59 , Figure 56 This is a three-dimensional structural diagram of the magnetic buckle 100f according to the sixth embodiment of the present invention. Figure 57 This is a partial structural schematic diagram of the magnetic buckle 100f according to the sixth embodiment of the present invention. Figure 58 and Figure 59 This is a structural schematic diagram of the magnetic buckle 100f according to the sixth embodiment of the present invention from different viewing angles. The magnetic buckle 100f of the sixth embodiment has a generally similar structure to the magnetic buckle 100d of the fourth embodiment, with the specific differences as follows:

[0206] First, such as Figures 56 to 59As shown, in this embodiment, the shoulder strap buckle 1 is stacked on the belt buckle 2 along the front and back directions of the magnetic buckle 100f. The belt buckle 2 has a locking part 22, preferably a locking hole. The shoulder strap buckle 1 includes an extension arm 102 that matches the contour of the locking part 22. The extension arm 102 is embedded in the locking part 22, thereby enhancing the visibility of the extension arm 102 of the shoulder strap buckle 1 from the front, making it easier for people to attach the shoulder strap buckle 1 to the belt buckle 2 from the front or the back. In the magnetic buckle 100d of the fourth embodiment, the extension arm 102 of the shoulder strap buckle 1 is embedded in the groove on the back of the belt buckle 2. That is to say, from the front, the extension arm 102 is hidden, and people cannot attach the shoulder strap buckle 1 to the belt buckle 2 from the front view. Therefore, the embedding method of the shoulder strap buckle 1 and the belt buckle 2 can be selected according to actual needs.

[0207] Second, such as Figures 56 to 59 As shown, in this embodiment, the first fastener 10 of the magnetic buckle 100f includes a first magnetic structure 7 disposed on the first fastener 10 and a second magnetic structure 8 disposed on the movable member 5 located within the second fastener 3, but does not include a third magnetic structure, thereby saving the volume and space of the first fastener 10 and reducing manufacturing costs. However, in the magnetic buckle 100d of the fourth embodiment, the first fastener 10 includes a first magnetic structure 7 disposed on the shoulder strap buckle 1 of the first fastener 10, a third magnetic structure 9 disposed on the waist belt buckle 1 of the first fastener 10, and a second magnetic structure 8 disposed on the movable member 5 located within the second fastener 3, and is therefore not limited thereto.

[0208] Apart from the differences mentioned above, the other structures of the magnetic buckle 100f in the sixth embodiment are roughly the same as those of the magnetic buckle 100d in the fourth embodiment, and therefore will not be described in detail here.

[0209] Please see Figures 60 to 64 , Figure 60 This is a schematic diagram of the structure of the magnetic buckle 100g according to the seventh embodiment of the present invention. Figure 61 This is a schematic diagram of the structure of the magnetic buckle 100g in the seventh embodiment of the present invention when the two first fasteners 10 are removed. Figure 62 and Figure 63 This is a partial structural diagram of the magnetic buckle 100g according to the seventh embodiment of the present invention from different perspectives. Figure 64 This is a partial structural schematic diagram of the magnetic buckle 100g according to the seventh embodiment of the present invention. The magnetic buckle 100g of the seventh embodiment has a generally similar structure to the magnetic buckle 100d of the fourth embodiment, with the specific differences as follows:

[0210] First, such as Figures 60 to 61As shown, in this embodiment, the first fastener 10 includes a shoulder strap buckle 1 and a waist belt buckle 2, which together form a male buckle with an integral structure. The second fastener 3 is a hip buckle 2. In the fourth embodiment, the shoulder strap buckle 1 and the waist belt buckle 2 are connected to each other.

[0211] Second, such as Figures 60 to 64 As shown, in this embodiment, the first fastener 10 only includes a first magnetic structure 7 disposed on the first fastener 10 and a second magnetic structure 8 disposed on the movable member 5 located within the second fastener 3, and does not include a third magnetic structure. In the fourth embodiment, the belt buckle 2 includes a first magnetic structure 7 disposed on the first fastener 10, a third magnetic structure 9 disposed on the belt buckle 1 of the first fastener 10, and a second magnetic structure 8 disposed on the movable member 5 located within the second fastener 3.

[0212] Third, such as Figures 62 to 64 As shown, in this embodiment, the release operation unit 4 directly drives the locking member 6 to perform the release movement. Specifically, the locking member 6 includes a linkage structure 151, and the release operation unit 4 includes a release linkage structure 141 that is linked to the linkage structure 151. Therefore, the release operation unit 4 uses the cooperation of the release linkage structure 141 and the linkage structure 151 to drive the locking structure 61 to release from the locking structure 103. More specifically, the release linkage structure 141 on the release operation unit 4 is a first inclined surface that is inclined relative to the sliding direction of the locking member 6, and the linkage structure 151 is a second inclined surface. Therefore, when the release operation unit 4 slides, the first inclined surface 141 pushes against the second inclined surface 151, thereby pushing the locking member 6 to slide along the release direction, thereby causing the locking structure 61 to disengage from the locking with the locking structure 103. In the fourth embodiment, the release operation unit 4 indirectly drives the locking member 6 to perform the release movement through the moving member 5. Specifically, the release operation unit 4 drives the moving member 5 to rotate. The rotation of the moving member 5 causes the release linkage structure 141 on the moving member 5 to cooperate with the linkage and engagement structure 151 on the locking member 6, thereby driving the locking structure 61 and the matching lock structure 103 to release. The release linkage structure 141 on the moving member 5 is a first spiral inclined surface whose spiral center line coincides with the pivot center line, and the linkage and engagement structure 151 is a matching second spiral inclined surface.

[0213] Apart from the differences mentioned above, the other structures of the magnetic buckle 100g in the seventh embodiment are roughly the same as those of the magnetic buckle 100d in the fourth embodiment, and therefore will not be described in detail here.

[0214] Please see Figures 65 to 68 , Figure 65 This is a front view of the magnetic buckle 100h according to the eighth embodiment of the present invention. Figure 66 This is a schematic diagram of the structure of the magnetic fastener 100h in the eighth embodiment of the present invention when the two first fasteners 10 are removed. Figure 67and Figure 68 This is an exploded view of the first fastener 10 according to the eighth embodiment of the present invention. The magnetic fastener 100h of the eighth embodiment has a generally similar structure to the magnetic fastener 100d of the fourth embodiment, with the following specific differences: Figures 65 to 68 As shown, in this embodiment, the first fastener 10 includes a shoulder strap buckle 1 and a waist belt buckle 2. The shoulder strap buckle 1 is slidably assembled to the waist belt buckle 2. Specifically, the waist belt buckle 2 has an insertion groove 2a, and the shoulder strap buckle 1 has an insertion portion 1a. The shoulder strap buckle 1 is assembled to the waist belt buckle 2 by inserting the insertion portion 1a into the insertion groove 2a. Preferably, the cross-section of the insertion portion 1a is T-shaped, and the cross-section of the insertion groove 2a corresponds to the cross-sectional shape of the insertion portion 1a. Furthermore, the shoulder strap buckle 1 in this embodiment does not have a third magnetic structure.

[0215] Apart from the differences mentioned above, the other structures of the magnetic buckle 100h in the eighth embodiment are roughly the same as those of the magnetic buckle 100d in the fourth embodiment, and therefore will not be described in detail here.

[0216] Please see Figures 69 to 71 , Figure 69 This is a three-dimensional structural diagram of the magnetic buckle 100i according to the ninth embodiment of the present invention. Figure 70 This is a schematic diagram of the magnetic fastener 100i of the ninth embodiment of the present invention when one of the first fasteners 10 is removed. Figure 71 This is a partial exploded view of the magnetic buckle 100i according to the ninth embodiment of the present invention. Figures 69 to 71 As shown, similar to the seventh embodiment, in this embodiment, the first fastener 10 includes a shoulder strap buckle 1 and a waist belt buckle 2, which together form an integral male buckle. The second fastener 3 is a crotch buckle. Each first magnetic structure 7 is disposed in the corresponding first fastener 10, and the second magnetic structure is disposed in the movable member 5 within the second fastener 3. Furthermore, the magnetic buckle 100i of this embodiment does not include a third magnetic structure. Apart from the above differences, the other structures of the magnetic buckle 100i of the ninth embodiment (e.g., the structure that drives the locking member 6 to disengage from the first fastener 10) are largely the same as those of the magnetic buckle 100d of the fourth embodiment, and therefore will not be described in detail here.

[0217] Please see Figures 72 to 76 , Figure 72 This is a three-dimensional structural diagram of the magnetic buckle 100j according to the tenth embodiment of the present invention. Figure 73 This is an exploded view of the magnetic buckle 100j according to the tenth embodiment of the present invention. Figure 74 This is a cross-sectional schematic diagram of the magnetic fastener 100j according to the tenth embodiment of the present invention. Figure 75 and Figure 76 This is a schematic diagram of the magnetic buckle 100j according to the tenth embodiment of the present invention in different states. Figures 72 to 76As shown, similar to the seventh embodiment, in this embodiment, the first fastener 10 includes a shoulder strap buckle 1 and a waist belt buckle 2, which together form an integral male buckle. The second fastener 3 is a crotch buckle. Each first magnetic structure 7 is disposed in the corresponding first fastener 10, and the magnetic buckle 100j in this embodiment does not include a third magnetic structure. However, unlike the seventh embodiment, the movable member 5 is fixedly connected to the release operation part 4. The second magnetic structure 8 is disposed on the movable member 5 and can slide with the release operation part 4. The second magnetic structure 8 includes a first magnetic part 81 and a second magnetic part 82, which are respectively disposed in the first setting cavity 5a and the second setting cavity 5b opened on the movable member 5. The first magnetic part 81 is used to magnetically attract the first magnetic structure 7, and the second magnetic part 82 is used to magnetically repel the first magnetic structure 7. In this embodiment, the first magnetic part 81 and the second magnetic part 82 can be two separate components, but the present invention is not limited to this. In another embodiment, the first magnetic part and the second magnetic part can be integrally formed.

[0218] When the release operation unit 4 is released and reset to its original position... Figure 75 When in the indicated position, the first magnetic part 81 aligns with the first magnetic structure 7, magnetically attracting the first magnetic structure 7, thereby assisting in the insertion of the first fastener 10 and the second fastener 3. When the release operation part 4 is operated and slides to the indicated position... Figure 76 When positioned as shown, the second magnetic part 82 aligns with the first magnetic structure 7, magnetically repelling the first magnetic structure 7, thereby assisting in the separation of the first fastener 10 and the second fastener 3. Apart from the differences described above, the other structures of the magnetic fastener 100j of the tenth embodiment are substantially the same as those of the magnetic fastener 100d of the fourth embodiment, and therefore will not be described in detail here.

[0219] Please see Figures 77 to 80 , Figure 77 This is a three-dimensional structural diagram of the magnetic buckle 100k according to the eleventh embodiment of the present invention. Figure 78 This is an exploded view of the magnetic buckle 100k according to the eleventh embodiment of the present invention. Figure 79 and Figure 80 This is a schematic diagram of the magnetic buckle 100k according to the eleventh embodiment of the present invention in different states. Figures 77 to 80As shown, similar to the seventh embodiment, in this embodiment, the first fastener 10 includes a shoulder strap buckle 1 and a waist belt buckle 2, which together form an integral male buckle. The second fastener 3 is a crotch buckle. Each first magnetic structure (not shown in the figure) is disposed in the corresponding first fastener 10, and the second magnetic structure 8 is disposed in the movable member 5 located within the second fastener 3. Furthermore, the magnetic buckle 100k in this embodiment does not include a third magnetic structure. Unlike the seventh embodiment, the release operation part 4 includes a first operation part 4a and a second operation part 4b. The first operation part 4a is used to drive the locking member 6 to disengage from the first fastener 10, and the second operation part 4b is used to drive the movable member 5 to change the magnetic direction of the second magnetic structure 8.

[0220] Specifically, the first operating part 4a and the second operating part 4b are slidably disposed on the second fastener 3 and can be operated independently. Preferably, in this embodiment, the sliding direction of the first operating part 4a is parallel to the positive and negative directions of the magnetic fastener 100k, and the sliding direction of the second operating part 4b is perpendicular to the sliding direction of the first operating part 4a. The release linkage structure 141 is formed on the first operating part 4a and is used to cooperate with the linkage cooperation structure 151 formed on the locking member 6. The linkage structure 10a is formed on the release operating part 4 and is used to cooperate with the matching structure 11a formed on the moving member 5. The first operating part 4a is also formed with a retaining structure 411, which is used to engage with the retaining engagement part 31 formed on the second fastener 3. The second operating part 4b is also formed with a release structure 421, which is used to drive the retaining structure 411 to disengage from the retaining engagement part 31.

[0221] When the first operating unit 4a is operated and moves along the first operating direction R1 as follows Figure 79 Slide to the position shown. Figure 80 When the position shown is such that the locking member 6 is disengaged from the first fastener 10, the retaining structure 411 can engage with the retaining engagement part 31 to maintain the first operating part 4a in the position shown. Figure 80 The position shown. When the first operating part 4a is positioned as shown by the engagement of the retaining structure 411 with the retaining engagement part 31. Figure 80After reaching the indicated position, the first operating part 4a can be released, and the second operating part 4b can be operated to slide along the second operating direction R2, which is perpendicular to the first operating direction R1. When the second operating part 4b slides along the second operating direction R2 and drives the moving member 5 to change the magnetic direction of the second magnetic structure 8, the release structure 421 pushes the retaining structure 411 to disengage the retaining structure 411 from the retaining engagement part 31, allowing the first operating part 4a to reset upwards (e.g., through an elastic member). In other words, the magnetic buckle 100k of this embodiment can provide a two-stage release and separation operation to prevent the first buckle 10 from accidentally separating from the second buckle 3, and the user can release the first operating part 4a after operating the first operating part 4a to drive the locking member 6 to disengage from the first buckle 10, making it more convenient to use.

[0222] However, the present invention is not limited thereto. For example, please refer to [link to relevant documentation]. Figure 81 and Figure 82 , Figure 81 and Figure 82 This is a schematic diagram of the magnetic buckle 100l of the twelfth embodiment of the present invention in different states. Figure 81 and Figure 82 As shown, the magnetic buckle 100l in this embodiment does not include a retaining structure. Therefore, when the first operating part 4a is operated to drive the locking member 6 to disengage from the first fastener (not shown in the figure), the position of the first operating part 4a cannot be maintained. In other words, in this embodiment, the user needs to use two hands or two fingers to operate the first operating part 4a and the second operating part 4b of the magnetic buckle 100l without releasing the first operating part 4a in order to separate the first fastener 10 from the second fastener 3.

[0223] Furthermore, it is understood that the structural and arrangement relationship between the first and second magnetic structures in any of the third to ninth embodiments and the eleventh to twelfth embodiments is the same as that in the second embodiment. Figures 12 to 14 The structure and settings shown are similar and can be replaced with, for example... Figures 23 to 25 or Figures 26 to 28 The structure and settings are shown.

[0224] Compared with the prior art, the magnetic buckle of the present invention utilizes the cooperation of a release operation part, a moving part, a locking part, a first magnetic structure, and a second magnetic structure. When the release operation part is operated to drive the locking part to release, the release operation part can be linked to the moving part to change the magnetic direction of the second magnetic structure. Therefore, the first magnetic structure and the second magnetic structure can magnetically attract each other during the insertion of the first buckle and the second buckle, and magnetically repel each other when the release operation part is operated to drive the locking part to release. Thus, the magnetic buckle of the present invention can simultaneously meet the requirements of fast fastening speed and fast release speed. Of course, the magnetic buckle of the present invention can also be configured such that the first magnetic structure and the second magnetic structure magnetically repel each other during the insertion of the first buckle and the second buckle, and magnetically attract each other when the release operation part is operated to drive the locking part to release, to meet special occasions such as preventing accidental separation or other occasions.

[0225] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
