Description

Technical Field

[0001] This application relates to the field of child safety seats, particularly to buckle assemblies.

Background Art

[0002] Child safety seats typically secure a child within the seat using a five - point seat belt. To prevent the child's shoulders from slipping out of the shoulder belts of the seat belt, some shoulder belts of child safety seats are provided with chest buckles. The male buckle and female buckle of the chest buckle are respectively fixed to two shoulder belts. After the buckle assembly of the five - point seat belt is locked, the male buckle and female buckle of the chest buckle are locked. This enables the child to be more securely fixed to the child safety seat.

[0003] However, after the currently commercially available chest buckle is unlocked, it is necessary to manually separate the male buckle and the female buckle. As a result, the current chest buckle is complex to operate and difficult to use.

[0069] In this application, the position of the first feature "above" or "below" the second feature may mean that the first and second features are in direct contact, or that they are indirectly in contact through an intermediate medium. In this specification, any description referring to terms such as "one embodiment," "several embodiments," "example," "specific example," or "several examples" means that the specific features, structures, materials, or characteristics described with reference to that embodiment or example are included in at least one embodiment or example of this application. In this specification, the general expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0070] The first embodiment of the present application will be described below.

[0071] This application provides a buckle assembly 1 that can be used in a child safety seat. Alternatively, the buckle assembly 1 can be used in a baby carrier, infant carrier, etc. Since the buckle assembly 1 of this application does not require manual separation of the male and female buckles after disengagement, it solves the technical problems of conventional chest buckles, such as the complexity of operation and inconvenience of use.

[0072] Referring to Figures 1 to 3, the buckle assembly 1 may include a male buckle 10 and a female buckle 20. The male buckle 10 may have a male buckle housing 11 that forms its exterior. The female buckle 20 may have a female buckle housing 21 that forms its exterior. The male buckle 10 fits with the female buckle 20 such that the male buckle 10 and the female buckle 20 engage with each other. An opening 213 may be formed on one side of the female buckle housing 21. A portion of the male buckle 10 is inserted into the female buckle 20 through the opening 213 and engages with the female buckle 20.

[0073] In one embodiment, the male buckle 10 has attachment portions 111 on each side. The female buckle 20 has attachment portions 211 on each side. The attachment portions 111 and 211 can be identical or similar in configuration, but are not limited thereto. In a specific embodiment, the attachment portions 111 and 211 may be formed in annular shape and attached by a belt (not shown). This belt is, for example, a seat belt used to restrain a child. The belt is attached by passing through at least a portion of the attachment portions 111 and 211. The attachment portions 111 and 211 may extend along the thickness direction (vertical direction in Figure 4) of the buckle assembly 1.

[0074] In some embodiments, the male buckle 10 has only one attachment portion 111. In some embodiments, the female buckle 20 has only one attachment portion 211.

[0075] The buckle assembly 1 includes a release button 12. The release button 12 is movably mounted on the male buckle 10. The release button 12 is partially exposed on the top of the male buckle housing 11. Specifically, at least a portion of the upper surface of the release button 12 is exposed to the outside of the male buckle housing 11. The release button 12 may have a recess 122. The recess 122 may be located on the portion of the release button 12 that is exposed outside the male buckle housing 11. The recess 122 can facilitate the operation of the release button 12. For example, an operator's finger may enter the recess 122 and drive the release button 12 to slide against the male buckle housing 11.

[0076] In one embodiment, the release button 12 does not have a recess 122, but has an easily operable protrusion (not shown).

[0077] Referring to Figure 2, the female buckle 20 may include an engaging portion 212. The engaging portion 212 can be formed at the bottom of the female buckle housing 21. The engaging portion 212 penetrates the bottom of the female buckle housing 21. For example, the engaging portion 212 is formed as an engaging hole. In selectable embodiments, the engaging portion 212 may be formed as a groove of a certain depth. The engaging portion 212 may be formed in a rectangular shape, but the present invention is not limited thereto.

[0078] In one embodiment, the female buckle 20 may include two engaging portions 212 arranged symmetrically in the lateral direction.

[0079] In some embodiments, the female buckle 20 includes only one engaging portion 212.

[0080] Referring to Figure 3, the front side of the male buckle housing 11 (i.e., the side of the male buckle housing 11 facing the female buckle 20) protrudes forward and includes a guide portion 113. The guide portion 113 is located at the foremost end of the male buckle housing 11. The guide portion 113 can be formed as a flattened tongue. The guide portion 113 is configured to guide the engagement between the male buckle 10 and the female buckle 20 (details will be described later). The release button 12 is slidable in the front-rear direction of the male buckle 10.

[0081] Referring to Figures 4 to 6, in this invention, when the male buckle 10 is fitted into the female buckle 20, the direction in which the male buckle 10 faces the female buckle 20 is the forward direction of the male buckle 10, and the direction in which the female buckle 20 faces the male buckle 10 is the forward direction of the female buckle 20. A recovery member 13 is provided between the release button 12 and the male buckle housing 11, and the recovery member 13 applies thrust to the release button 12 in the forward direction of the male buckle 10 (to the left in Figure 4). The recovery member 13 may be a coil spring, but the present invention is not limited thereto.

[0082] The buckle assembly 1 includes a rotating member 17. The rotating member 17 is rotatably mounted on the male buckle 10. The rotating member 17 is mounted on the male buckle 10 via a pivot 172, thereby enabling the rotating member 17 to rotate relative to the male buckle 10.

[0083] A closed housing cavity 214 is formed inside the female buckle 20. A first magnetic component 22 may be provided inside the housing cavity 214. A second magnetic component 18 is fixed to the rotating member 17. The second magnetic component 18 is rotatable with respect to the male buckle 10 together with the rotating member 17.

[0084] In the process of mating the male buckle 10 and the female buckle 20, the second magnetic component 18 and the guide portion 113 of the male buckle 10 enter the female buckle 20 through the opening 213 of the female buckle housing 21. The opening 213 and the internal space of the female buckle housing 21 can be shaped to correspond to the second magnetic component 18 and the guide portion 113, thereby smoothly guiding the male buckle 10 into the female buckle 20.

[0085] In some embodiments, the male buckle 10 has a male buckle lower cover 112. The male buckle lower cover 112 is detachably provided at the bottom of the male buckle 10, thereby facilitating the installation and removal of internal components of the male buckle 10. In some embodiments, the male buckle lower cover 112 constitutes part of the male buckle housing 11 and is fixedly connected to the rest of the male buckle housing 11.

[0086] As shown in Figure 4, when the male buckle 10 and the female buckle 20 are mated, the guide portion 113 is at least partially located below the first magnetic component 22. The thickness of the guide portion 113 corresponds to the height of the space below the housing cavity 214 of the female buckle housing 211, thereby limiting the position of the guide portion 113. This allows the first magnetic component 22 and the second magnetic component 18 to be aligned when the male buckle 10 and the female buckle 20 are mated.

[0087] Referring to Figures 7 and 8, the buckle assembly 1 includes an engaging member 14. The engaging member 14 engages the male buckle 10 and the female buckle 20. The engaging member 14 is located at the front of the male buckle 10 (left side in Figure 7). The engaging member 14 has a first inclined surface 142. The first inclined surface 142 may face downward and forward (down-left in Figure 7) of the male buckle 10. The rear portion of the first inclined surface 142 of the engaging member 14 (right side in Figure 7) can be a vertical surface 1421. When the male buckle 10 and the female buckle 20 are fitted together, a portion of the engaging member 14 is inserted into the engaging portion 212 and catches on the engaging portion 212, thereby preventing the male buckle 10 and the female buckle 20 from separating.

[0088] Referring to Figures 9 and 10, in some embodiments, the engaging member 14 includes two first inclined surfaces 142. The two first inclined surfaces 142 are arranged symmetrically in the lateral direction of the male buckle 10. The two first inclined surfaces 142 may each be located on either side of the rotating member 17.

[0089] In another embodiment, the buckle assembly 1 includes only one engaging member 14 having only one first inclined surface 142.

[0090] Referring to Figures 7 and 8, the upper surface of the engaging member 14 has a groove 141. An elastic member 15 is provided between the male buckle housing 11 and the groove 141. The elastic member 15 applies thrust to the engaging member 14, causing the engaging member 14 to move downward. In the process of fitting the male buckle 10 and the female buckle 20, as the engaging member 14 passes through the engaging portion 212, the thrust of the elastic member 15 causes the engaging member 14 to partially enter the engaging portion 212, thereby achieving engagement between the male buckle 10 and the female buckle 20. As a specific example, the elastic member 15 may be a coil spring, but the present invention is not limited thereto. The groove 141 can restrict the movement of the elastic member 15, making the structure of the buckle assembly 1 more secure.

[0091] Referring to Figures 9 and 10, the release button 12 includes an arm portion 123. The arm portion 123 extends in the direction in which the male buckle 10 and the female buckle 20 are fitted together. In other words, the arm portion 123 extends from the release button 12 toward the front of the male buckle 10. For example, the arm portion 123 may be an elongated rod shape, but the present invention is not limited thereto. The release button 12 includes a drive block 124. The drive block 124 is formed at the free end (tip) of the arm portion 123. The drive block 124 extends laterally from the arm portion 123. That is, the drive block 124 extends perpendicular to the arm portion 123. The rotating member 17 includes a gear 171. The gear 171 is formed at the lower part of the rotating member 17 (lower part in Figure 4), but is not limited thereto. The gear 171 may have a common pivot axis with the pivot 172. The release button 12 includes a rack 121. The rack 121 is formed on the arm portion 123. A gear 171 meshes with the rack 121. Specifically, the drive block 124 and the rack 121, both located on the same arm portion 123, protrude laterally from the arm portion 123 in opposite directions.

[0092] In one embodiment, the release button 12 includes two arm portions 123. Both arm portions 123 extend in a direction parallel to the direction in which the male buckle 10 and the female buckle 20 are fitted together. Two drive blocks 124 are formed at the free ends of the two arm portions 123, respectively. Each of the two drive blocks 124 extends laterally outward from the two arm portions 123. One of the two arm portions 123 includes a rack 121. A gear 171 is located between the two arm portions 123 and can mesh with the rack 121.

[0093] In some embodiments, the release button 12 includes one arm portion 123.

[0094] Furthermore, if the release button 12 is not operated and the male buckle 10 and female buckle 20 are positioned facing each other, the first magnetic component 22 and the second magnetic component 18 are oriented to magnetically attract each other. When the male buckle 10 and female buckle 20 are fitted together, the first magnetic component 22 and the second magnetic component 18 gradually generate an attractive force, assisting the process of the male buckle 10 and female buckle 20 moving closer to each other. Once the male buckle 10 and female buckle 20 are fully fitted together, the engaging member 14 engages with the engaging portion 212, and the first magnetic component 22 and the second magnetic component 18 are adjacent to each other (see Figure 4).

[0095] When separating the male buckle 10 and the female buckle 20, first, the release button 12 is activated backward (to the right in Figure 4), moving the release button 12 backward relative to the male buckle housing 11 against the restoring force of the recovery member 13, that is, the male buckle 10 engages with the female buckle 20 along a first direction (for example, to the left in Figure 4), and the release button 12 is activated in a second direction (for example, to the right in Figure 4), such that the direction in which the male buckle 10 and the female buckle 20 engage (first direction) and the direction in which the release button 12 is activated (second direction) are collinear and opposite to each other. As shown in Figures 9 and 10, when the release button is activated in the second direction, the release button 12 moves backward, driving the drive block 124 by bringing it into contact with the first inclined surface 142, thereby moving the engaging member 14 upward (upward in Figure 4) against the restoring force of the elastic member 15. Ultimately, the engaging member 14 separates from the engaging portion 212, thereby disengaging the male buckle 10 and the female buckle 20. Meanwhile, when the release button 12 moves backward, the rack 121 of the release button 12 moves backward. Since the rack 121 in the arm portion 123 meshes with the gear 171 in the rotating member 17, the movement of the rack 121 causes the gear 171 to rotate. The distance the release button 12 moves is set so that the rack 121 rotates the gear 171 by approximately 180°. In other words, when the release button 12 is activated, the magnetic poles of the second magnetic component 18 in the rotating member 17 are reversed. Thus, the first magnetic component 22 and the second magnetic component 18 change to magnetically attract and magnetically repel each other. When the engaging member 14 separates from the engaging portion 212, the first magnetic component 22 acts a magnetic repulsive force on the second magnetic component 18, easily separating the male buckle 10 and the female buckle 20. In other words, the male buckle 10 automatically moves the female buckle housing 21. After the male buckle 10 and the female buckle 20 are separated, when the release button 12 is no longer activated, the recovery member 13 drives the release button 12 back to its initial position, and at the same time, the rack 121 in the release button 12 drives the gear 171 to rotate, which drives the second magnetic component 18 back to its initial position.

[0096] In some embodiments, it can be understood that when the release button 12 is activated, the magnetic poles of the second magnetic component 18 on the rotating member 17 do not reverse. When the male buckle 10 and the female buckle 20 are separated, the first magnetic component 22 and the second magnetic component 18 continue to hold each other by magnetic attraction. At this time, an external force must be applied to separate the male buckle 10 and the female buckle 20.

[0097] Referring to Figure 11, the male buckle 10 and the female buckle 20 are fitted together. The first magnetic component 22 may be formed in a rectangular cross-section, and the opposite side of the second magnetic component 18 may be formed in an arc shape that is advantageous for rotation and as close as possible to the first magnetic component 22. The shapes of the first magnetic component 22 and the second magnetic component 18 are illustrative. In other embodiments, the first magnetic component 22 and the second magnetic component 18 may be formed in different shapes.

[0098] In another embodiment, a first magnetic component 22 is provided on the male buckle 10, and a second magnetic component 18 is provided on the female buckle 20. That is, by rotating the second magnetic component 18 in the female buckle 20 relative to the first magnetic component 22 in the male buckle 10, a change from mutual magnetic attraction to mutual magnetic repulsion can be achieved.

[0099] Referring to Figures 4, 9, and 10, the direction of movement of the engaging member 14 is the vertical direction in Figure 4, the direction of engagement between the male buckle 10 and the female buckle 20 is the left-right direction in Figure 4, and the direction of the rotation axis of the second magnetic component 18 is the vertical direction in Figure 4. That is, the direction of movement of the engaging member 14 is perpendicular to the direction of engagement between the male buckle 10 and the female buckle 20, perpendicular to the direction of movement of the release button 12, and parallel to the rotation axis of the second magnetic component 18.

[0100] The first magnetic component 22 is fixed and installed on the female buckle 20, and the second magnetic component 18 is rotated and installed on the male buckle 10. By aligning the male buckle 10 and the female buckle 20 in this way, the first magnetic component 22 and the second magnetic component 18 are magnetically attracted to each other along the mating direction, allowing the male buckle 10 and the female buckle 20 to be engaged. The magnetic attraction between the first magnetic component 22 and the second magnetic component 18 automatically engages the male buckle and the female buckle, making it convenient to use. At the same time, when the buckle assembly 1 is unlocked, the release button 12 rotates the second magnetic component 18, causing magnetic repulsion between the first magnetic component 22 and the second magnetic component 18, thereby automatically separating the male buckle 10 and the female buckle 20. Therefore, the buckle assembly 1 of this invention is easy to operate and convenient to use.

[0101] The second embodiment of the present application will be described below. In the following, the differences between the second embodiment and the first embodiment will be mainly described, and the parts that are the same as those of the first embodiment will be omitted from the description in order to avoid duplication.

[0102] Referring to Figure 12, the male buckle 10 includes two belt holes 114. The two belt holes 114 may be formed in two attachment portions 111, respectively. A belt (not shown) can pass through the two belt holes 114 in sequence to attach the male buckle 10 to the belt. This belt may be, for example, a seat belt of a child safety seat, but the present invention is not limited thereto.

[0103] Continuing to refer to Figure 12, the female buckle 20 includes two belt holes 215. The two belt holes 215 may be formed in two attachment portions 211, respectively. Another belt (not shown) can pass through the two belt holes 215 sequentially to attach the female buckle 20 to the belt. This belt may be, for example, a seat belt of a child safety seat, but the present invention is not limited thereto.

[0104] Referring to Figure 13, the male buckle housing 11 includes a male buckle elastic sheet 115. The male buckle elastic sheet 115 may be integrally molded with the male buckle lower cover 112, but the present invention is not limited thereto. Alternatively, the male buckle elastic sheet 115 may be formed separately from the male buckle lower cover 112 and fixed in place. The male buckle elastic sheet 115 is located below the male buckle lower cover 112. The belt, having passed through the two belt holes 114, passes through the gap between the male buckle elastic sheet 115 and the male buckle lower cover 112 and is jointly clamped by the male buckle elastic sheet 115 and the male buckle lower cover 112.

[0105] Continuing to refer to Figure 13, the female buckle 20 may have a female buckle lower cover 216. The female buckle lower cover 216 is removablely provided at the bottom of the female buckle 20 to facilitate the removal of internal components of the female buckle 20. In other embodiments, the female buckle lower cover 216 constitutes part of the female buckle housing 21 and is fixedly connected to the rest of the female buckle housing 21. The female buckle housing 21 may include a female buckle elastic sheet 217. The female buckle elastic sheet 217 may be integrally molded with the female buckle lower cover 216, but the present invention is not limited thereto. Alternatively, the female buckle elastic sheet 217 may be formed separately from the female buckle lower cover 216 and fixed in place. The female buckle elastic sheet 217 may be located below the female buckle lower cover 216. The belt, having passed through the two belt holes 215, passes through the gap between the female buckle elastic sheet 217 and the female buckle lower cover 216, and is jointly clamped by the female buckle elastic sheet 217 and the female buckle lower cover 216.

[0106] Referring to Figures 14 and 15, the male buckle elastic sheet 115 includes an elastically deformable portion 1151 and a clamp portion 1152. The elastically deformable portion 1151 may connect the clamp portion 1152 and the male buckle lower cover 112. The elastically deformable portion 1151 may be connected to the side of the lower surface of the male buckle lower cover 112 away from the female buckle 20, but the present invention is not limited thereto. The elastically deformable portion 1151 is elastically deformable and provides elastic recovery force. In a specific example, the elastically deformable portion 1151 may be a curved sheet, but the present invention is not limited thereto. The gap between the clamp portion 1152 and the male buckle lower cover 112 may be smaller than the thickness of the belt passing through the two belt holes 114. In this way, when the belt is inserted into the gap between the clamp portion 1152 and the male buckle lower cover 112, the gap is expanded by the belt (i.e., the clamp portion 1152 is pushed downward by the belt). The elastically deformable portion 1151 deforms elastically as the clamp portion 1152 moves, applying a clamping force (recovery force) to the belt. As a result, the male buckle 10 is firmly clamped to the belt, preventing the belt from slipping or loosening.

[0107] Continuing to refer to Figures 14 and 15, the female buckle elastic sheet 217 includes an elastically deformable portion 2171 and a clamp portion 2172. The elastically deformable portion 2171 connects the clamp portion 2172 to the female buckle lower cover 216. The elastically deformable portion 2171 may be connected to the side of the lower surface of the female buckle lower cover 216 that is farther from the male buckle 10, but the present invention is not limited thereto. The elastically deformable portion 1151 is elastically deformable and provides elastic recovery force. In a specific example, the elastically deformable portion 2171 may be a curved sheet, but the present invention is not limited thereto. The gap between the clamp portion 2172 and the female buckle lower cover 216 may be smaller than the thickness of the belt passing through the two belt holes 215, so when the belt is inserted into the gap between the clamp portion 2172 and the female buckle lower cover 216, the gap is expanded by the belt (i.e., the clamp portion 2172 is pushed downward by the belt). The elastically deformable portion 2171 deforms elastically as the clamp portion 2172 moves, applying a clamping force (recovery force) to the belt. As a result, the female buckle 10 is firmly clamped to the belt, preventing the belt from slipping or loosening.

[0108] In some embodiments, the buckle assembly 1 may have only a male buckle lower cover 112 and a male buckle elastic sheet 115, and may not have a female buckle lower cover 216 and a female buckle elastic sheet 217.

[0109] Alternatively, the buckle assembly 1 may have only the female buckle lower cover 216 and the female buckle elastic sheet 217, and may not have the male buckle lower cover 112 and the male buckle elastic sheet 115.

[0110] Referring to Figures 16 and 17, the female buckle lower cover 216 includes at least one positioning projection 2161. Specifically, the female buckle lower cover 216 may include four positioning projections 2161. The four positioning projections 2161 are provided on each of the four sides of the female buckle lower cover 216. For example, the four positioning projections 2161 are provided on the sides of the female buckle lower cover 216 facing and behind the male buckle 10, and on both sides in the lateral direction, respectively, but the present invention is not limited thereto. Therefore, the female buckle housing 21 may have at least one positioning recess 218. Specifically, the female buckle housing 21 may include four positioning recesses 218. The four positioning projections 2161 and the four positioning recesses 218 correspond one-to-one and engage with each other, thereby fixing the female buckle lower cover 216 to the female buckle housing 21.

[0111] Alternatively, the female buckle lower cover 216 may include a positioning recess 218, and the female buckle housing 21 may include a positioning projection 2161.

[0112] Alternatively, the female buckle lower cover 216 may have another number of positioning protrusions 2161, such as three, five, or six.

[0113] Alternatively, the female buckle housing 21 may have another number of positioning recesses 218, such as three, five, or six.

[0114] In one embodiment, the number of positioning protrusions 2161 is equal to the number of positioning recesses 218.

[0115] In other embodiments, the number of positioning protrusions 2161 is not equal to the number of positioning recesses 218.

[0116] Referring to Figures 18 and 19, the male buckle lower cover 112 includes at least one positioning projection 1121. Specifically, the male buckle lower cover 112 includes five positioning projections 1121. The five positioning projections 1121 are provided on three of the four sides of the male buckle lower cover 112. For example, one positioning projection 1121 is provided on the side of the male buckle lower cover 112 that is away from the female buckle 20, and two positioning projections 1121 are provided on the other two sides of the male buckle lower cover 112, but the present invention is not limited thereto. Therefore, the male buckle housing 11 includes at least one positioning recess 116. Specifically, the male buckle housing 11 includes five positioning recesses 116. The five positioning projections 1121 and the five positioning recesses 116 correspond one-to-one and engage with each other, thereby fixing the male buckle lower cover 112 to the male buckle housing 11.

[0117] Alternatively, the male buckle lower cover 112 may include a positioning recess 116, and the male buckle housing 11 may include a positioning projection 1121.

[0118] Alternatively, the male buckle lower cover 112 may have another number of positioning protrusions 1121, such as three, four, six, or seven.

[0119] Alternatively, the male buckle housing 11 may have another number of positioning recesses 116, such as three, four, six, or seven.

[0120] In one embodiment, the number of positioning protrusions 1121 is equal to the number of positioning recesses 116.

[0121] In other embodiments, the number of positioning protrusions 1121 is not equal to the number of positioning recesses 116.

[0122] Referring to Figures 16 and 18, the length of the male buckle lower cover 112 may be greater than the length of the female buckle lower cover 216. As shown in Figure 15, a portion of the male buckle lower cover 112 may be inserted into the female buckle 20. Since the length of the male buckle lower cover 112 is greater than the length of the female buckle lower cover 216, the number of positioning protrusions 1121 on the male buckle lower cover 112 may be greater than the number of positioning protrusions 2161 on the female buckle lower cover 216.

[0123] By providing the male buckle elastic sheet 115 and / or the female buckle elastic sheet 217, the belt attached to the male buckle 10 and / or the female buckle 20 can be clamped, preventing the seat belt from loosening, avoiding displacement of the male buckle 10 and / or the female buckle 20 relative to the seat belt, thereby improving safety and ease of operation.

[0124] For other parts of the second embodiment, please refer to the relevant description in the first embodiment. Features of the second embodiment may be applied to the first embodiment, and vice versa.

[0125] The following describes a third embodiment of this disclosure. The following description will mainly focus on the differences between the third embodiment and the first embodiment, and will omit descriptions of parts that are the same as those in the first embodiment in order to avoid duplication.

[0126] Referring to Figures 20 to 23, the buckle assembly 1 includes a male buckle 10 and a female buckle 20 that mate with each other. The release button 12 is movably mounted on the male buckle 10. The release button 12 is partially exposed on the top of the male buckle housing 11 and protrudes from the top of the male buckle housing 11. This makes it easier to operate the release button 12 without inserting a finger into the male buckle housing 11. In this embodiment, the mounting portions 111 and 211 extend along the width direction (left-right direction in Figure 25) of the buckle assembly 1.

[0127] Referring to Figures 21 and 22, the female buckle 20 may include a mating guide portion 219. The mating guide portion 219 protrudes from the bottom of the female buckle 20 toward the male buckle 10. The mating guide portion 219 is formed integrally with the bottom surface of the female buckle housing 21. The engaging portion 212 is located on the mating guide portion 219. In a specific example, the engaging portion 212 may be formed as an engaging hole. The engaging hole may have a substantially rectangular shape. In this embodiment, the engaging portion 212 is formed by one engaging hole. In other embodiments, the engaging portion 212 may be formed by two or more engaging holes.

[0128] Referring to Figure 23, the male buckle housing 11 includes a guide portion 113. The guide portion 113 is located at the foremost end of the male buckle housing 11. The guide portion 113 can be formed as a relatively flat tongue. When the male buckle 10 and the female buckle 20 are fitted together, the guide portion 113 contacts the upper surface of the fitting guide portion 219, thereby guiding the fitting of the male buckle 10 and the female buckle 20.

[0129] Referring to Figures 21 and 25, the female buckle 20 includes a first magnetic component holder 23. The female buckle housing 21 has a housing cavity 214 for housing the first magnetic component 22. The housing cavity 214 opens at the bottom of the female buckle housing 21. The first magnetic component holder 23 is engageable with the female buckle housing 21 to secure the first magnetic component 22 to the female buckle housing 21 (specifically, the housing cavity 214).

[0130] Positioning protrusions 231 may be formed on the first magnetic component holder 23. Positioning recesses 2141 are formed on the female buckle housing 21. The positions of the positioning protrusions 231 and the positioning recesses 2141 correspond to each other. The first magnetic component holder 23 may be joined to the female buckle housing 21 by the engagement of the positioning protrusions 231 and the positioning recesses 2141. The number of positioning protrusions 231 may be equal to the number of positioning recesses 2141; for example, the number of positioning protrusions 231 and positioning recesses 2141 may both be 2, 4, 8, or other numbers.

[0131] As shown in Figure 24, in this embodiment, a portion of the guide portion 113 is positioned above the first magnetic component 22 when fitted to the male buckle 10 and the female buckle 20. The male buckle housing 11 has a male buckle lower cover 112 and a male buckle upper cover 117 that are connected to each other. The male buckle lower cover 112 and the male buckle upper cover 117 are snap-fitted, but are not limited to this. The male buckle lower cover 112 has a housing hole 1123. The engaging member 14 is movably positioned within the housing hole 1123. The male buckle 10 includes a fixed seat 19. The fixed seat 19 is fixed within the housing hole 1123. Specifically, the fixed seat 19 covers the upper side of the housing hole 1123. The engaging member 14 is connected to the fixed seat 19 by an elastic member 15. That is, the engaging member 14 is attached to the fixed seat 19 by an elastic member 15. The fixed seat 19 has a connecting arm 191. The male buckle lower cover 112 has a slot 1122. The slot 1122 is located around the housing hole 1123. The connecting arm 191 of the fixing seat 19 is inserted into the slot 1122. The upper end of the fixing seat 19 abuts against the release button 12 for positioning. The fixing seat 19 may have, but is not limited to, two connecting arms 191. The elastic member 15 is, for example, a coil spring, but is not limited to that. When the elastic member 15 is stationary, a portion of the engaging member 14 protrudes from the housing hole 1123. When the male buckle 10 and the female buckle 20 are fitted together, the engaging member 14 enters the engaging portion 212, preventing the male buckle 10 and the female buckle 20 from moving relative to each other in the lateral and / or front-to-back directions (engaging the male buckle 10 and the female buckle 20 with each other). The lower surface of the engaging member 14 is formed as a first inclined surface, and when the male buckle 10 and the female buckle 20 are fitted together, the engaging member 14 is driven to move into the housing hole 1123 by contacting the fitting guide portion 219 with the first inclined surface, so as not to hinder the relative movement of the male buckle 10 and the female buckle 20. The first inclined surface is positioned toward the fitting direction of the male buckle 10 and the female buckle 20 and has a guide function.When the first inclined surface enters the female buckle 20, the engaging member 14 comes into contact with the inner wall of the fitting guide portion 219 and becomes movable into the housing hole 1123, and the elastic member 15 is compressed. When the engaging member 14 aligns with the engaging portion 212 in the thickness direction, a part of the engaging member 14 protrudes from the housing hole 1123 due to the biasing force of the elastic member 15, and engagement can be achieved without pressing the release button 12.

[0132] Referring to Figure 26, the engaging member 14 includes a drive rod 143, or the buckle assembly 1 includes a drive rod 143 provided on the engaging member 14, and the release button 12 has a drive block 124, or the buckle assembly 1 has a drive block 124 connected to the release button 12. The drive block 124 has a second inclined surface 1241. The release button 12 can move the engaging member 14 by driving the drive rod 143 via the second inclined surface 1241. The drive block 124 is movably located below the release button 12, and the movement of the release button 12 moves the drive block 124 in conjunction with it. Specifically, to unlock the buckle assembly 1, the release button 12 is pressed along the direction of the arrow shown in Figure 26, causing the release button 12 and the drive block 124 to move together. The second inclined surface 1241 of the drive member 124 pushes the drive rod 143, thereby moving the engaging member 14 upward (upward as shown in Figure 24) and disengaging it from the engaging portion 212 (i.e., unlocking the buckle assembly 1). At this time, the male buckle 10 and the female buckle 20 can move away from each other and be separated.

[0133] As shown in Figures 27 to 29, the release button 12 in this embodiment has an arm portion 123, similar to the first embodiment. The release button 12 has two arm portions 123 that are parallel to each other. The rotating member 17 has a gear 171. A rack 121 is formed on one of the two arm portions 123. The gear 171 meshes with the rack 121. In this embodiment, the position of the drive block 124 differs from that of the first embodiment; specifically, the drive block 124 is formed below the release button 12.

[0134] The release button 12 drives the engaging member 14 to unlock and simultaneously rotates the second magnetic component 18. Specifically, as described above, when the release button 12 moves the engaging member 14 upward and disengages it from the engaging portion 212, one of the two arm portions 123 of the release button 12, the rack 121, moves and rotates the gear 171 that meshes with the rack 121 by approximately 180°, thereby reversing the magnetic poles of the second magnetic component 18 of the rotating member 17. As a result, the magnetic attraction between the first magnetic component 22 and the second magnetic component 18 changes from a mutual magnetic attraction to a mutual magnetic repulsion. After the engaging member 14 disengages from the engaging portion 212, the magnetic repulsion force of the first magnetic component 22 against the second magnetic component 18 facilitates the disengagement of the male buckle 10 from the female buckle 20. That is, the male buckle 10 automatically disengages from the female buckle housing 21. After the male buckle 10 detaches from the female buckle 20, if the release button 12 is no longer operated, the recovery member 13 drives the release button 12 back to its initial position, and the rack 121 in the release button 12 rotates the gear 171, driving the second magnetic component 18 back to its initial position.

[0135] Referring to Figure 28, the male buckle 10 has one drive block 124 on each of its left and right sides. The engaging member 14 has one connecting arm 191 on each of its front and rear sides. The connecting arm 191 can stably fix the fixing seat 19 to the male buckle housing 11, and stably fix the recovery member 15 and the engaging member 14 within the housing space via the fixing seat 19, and can stably engage and disengage the engaging member 14.

[0136] In the third embodiment, the guide portion 113 is located at least partially above the first magnetic component 22, and the engaging member 14 and the release button 12 are located on both sides of the male buckle 10 in the thickness direction (up and down direction in Figure 24). The release button 12 extends from the upper cover 117 of the male buckle and is operated, and the engaging member 14 extends from the lower cover 112 of the male buckle and engages with the female buckle 20.

[0137] In the third embodiment, by installing the drive blocks 124 on both sides of the engaging member 14, the drive blocks 124 can better drive the engaging member 14 to unlock it, and the size of the buckle assembly 1 can be reduced.

[0138] For other parts of the third embodiment, please refer to the relevant description of the first embodiment. Features of the third embodiment may be applied to the first embodiment, and vice versa.

[0139] A person skilled in the art will readily conceive of other embodiments of the Application after carrying out the invention disclosed herein in consideration of the specification. The Application is intended to cover any variations, uses, or adaptive changes of the Application, which include common or conventional means in the Art not disclosed herein, in accordance with the general principles of the Disclosure. The Specification and Examples are illustrative only, and the true scope and spirit of the Application are indicated by the Claims of the Application.

[0140] While this application has been described with reference to typical embodiments, the terminology used is descriptive and illustrative, not restrictive. Since this application can be specifically implemented in various forms without departing from the spirit and substance of this application, the above embodiments are not limited to any of the aforementioned details, but should be interpreted most broadly within the scope of the claims, and therefore, all variations falling within the scope of the claims or equivalents should be covered by the claims.
