The first inclined surface 142 faces downward and forward (bottom left of FIG. 7) of the male buckle 10. A portion of the engaging member 14 at the rear (right side of FIG. 7) of the first inclined surface 142 is formed as a vertical plane 1421. When the male buckle 10 is mated with the female buckle 20, a part of the engaging member 14 is inserted into the engaging portion 212, thereby hooking the engaging portion 212 to prevent the male buckle 10 from being disengaged from the female buckle 20.

[00117] Referring to FIGS. 9 and 10, in some embodiments, the engaging member 14 includes two first inclined surfaces 142. The two first inclined surfaces 142 are symmetrically arranged in a transverse direction of the male buckle 10. The two first inclined surfaces 142 are respectively located at opposite sides of the rotary member 17.

[00118] In an alternative embodiment, the buckle assembly 1 includes only one engaging member 14 with only one first inclined surface 142.

[00119] Referring to FIGS. 7 and 8, the upper surface of the engaging member 14 has a groove 141. Aresilient member 15 is provided between the male buckle housing 11 and the groove 141. The resilient member 15 applies a thrust to the engaging member 14 such that the engaging member 14 tends to move downward. In the process of mating the male buckle 10 and the female buckle 20, when the engaging member 14 passes the engaging portion 212, the engaging member 14 partially enters into the engaging portion 212 due to the thrust of the resilient member 15, such that the male buckle 10 and the female buckle 20 are engaged. As a specific example, the resilient member 15 is a helical spring, but the present disclosure is not limited thereto. The groove 141 restricts the movement of the resilient member 15, such that a structure of the buckle assembly 1 is more reliable.

[00120] Referring to FIGS. 9 and 10, the release button 12 includes an arm portion 123. The arm portion 123 extends in a mating direction of the male buckle 10 and the female buckle 20. In other words, the arm portion 123 extends toward a forward direction of the male buckle 10 from the release button 12. For example, the arm portion 123 is in an elongated-rod shape, but the present disclosure is not limited thereto. The release button 12 includes a driving block 124. The driving block 124 is formed at a free end (front end) of the arm portion 123. The driving block 124 extends laterally from the arm portion 123. That is, the driving block 124 extends in a direction perpendicular to the arm portion 123. The rotary member 17 comprises a gear 171. The gear 171 is formed at a lower portion (lower portion in FIG. 4) of the rotary member 17, but the present disclosure is not limited thereto. The gear 171 may have a common pivot axis with the pivot shaft 172. The release button 12 includes a rack 121. The rack 121 is formed on the arm portion 123. The gear 171 is meshed with the rack 121. Specifically, the driving block 124 and the rack 121 on the same arm portion 123 each protrude laterally in opposite directions from that arm portion 123.

[00121] In one embodiment, the release button 12 includes two arm portions 123. The two arm portions 123 each extend in a direction parallel to the mating direction of the male buckle 10 and the female buckle 20. Two driving blocks 124 are formed at free ends of the two arm portions 123 respectively. The two driving blocks 124 laterally extend outwardly from the two arm portions 123 respectively. One of the two arm portions 123 includes the rack 121. The gear 171 is located between the two arm portions 123 and meshed with the rack 121.

[00122] In some embodiments, the release button 12 includes only one arm portion 123.

[00123] When the release button 12 is not operated and the male buckle 10 and the female buckle 20 are provided opposite to each other, the first magnetic component 22 and the second magnetic component 18 are in a magnetically attractive orientation with each other. When the male buckle 10 is mated with the female buckle 20, the first magnetic component 22 and the second magnetic component 18 gradually generate an attractive force, thereby assisting a process of the male buckle 10 and the female buckle 20 approaching to each other. When the mating of the male buckle 10 and the female buckle 20 is completed, the engaging member 14 is engaged at the engaging portion 212, and the first magnetic component 22 and the second magnetic component 18 are adjacent to each other (referring to FIG. 4).

[00124] When separating the male buckle 10 and the female buckle 20, the release button 12 is firstly operated backward (toward the right in FIG. 4) such that the release button 12 is moved backward relative to the male buckle housing 11 against a restoring force of the restoring member 13. That is, the male buckle 10 is mated with the female buckle 20 in a first direction (e.g., toward the left in FIG. 4), the release button 12 is operated in a second direction (e.g., toward the right in FIG. 4), and the mating direction of the male buckle 10 with the female buckle 20 (the first direction) is collinear with and opposite to the direction in which the release button 12 is operated (the second direction). The release button is operated in the second direction as shown in FIGS. 9 and 10, and a backward movement of the release button 12 causes the driving block 124 to abut against and drive the first inclined surface 142, such that the engaging member 14 is moved upward (upward in FIG. 4) against the restoring force of the resilient member 15. Finally, the engaging member 14 would leave the engaging portion 212, such that the male buckle 10 and the female buckle 20 are disengaged. Meanwhile, the backward movement of the release button 12 causes the rack 121 on the release button 12 moving backward. Since the rack 121 on the arm portion 123 is meshed with the gear 171 on the rotary member 17, the movement of the rack 121 causes rotation of the gear 171. A moving distance of the release button 12 is configured such that the rack 121 rotates the gear 171 by about 180°. That is, when the release button 12 is operated, magnetic poles of the second magnetic component 18 on the rotary member 17 are reversed. As such, magnetic attraction of the first magnetic component 22 and the second magnetic component 18 would change to magnetic repulsion of the first magnetic component 22 and the second magnetic component 18. After the engaging member 14 leaves the engaging portion 212, a magnetic repulsion force of the first magnetic component 22 against the second magnetic component 18 facilitates the separation of the male buckle 10 from the female buckle 20. That is, the male buckle 10 would automatically move out of the female buckle housing 21. When the release button 12 is no longer operated after the male buckle 10 is separated from the female buckle 20, the restoring member 13 will drive the release button 12 to return to an initial position, meanwhile the rack 121 on the release button 12 drives the gear 171 to rotate, thereby driving the second magnetic component 18 back to an initial position.

[00125] It should be understood that in some embodiments, the magnetic poles of the second magnetic component 18 on the rotary member 17 are not reversed when the release button 12 is operated. As such, the first magnetic component 22 and the second magnetic component 18 will continue to remain magnetically attracted to each other when the male buckle 10 and the female buckle 20 are disengaged. At this case, an external force is needed to separate the male buckle 10 from the female buckle 20.

[00126] Referring to FIG. 11, the male buckle 10 is mated with the female buckle 20. The first magnetic component 22 is formed in a shape having a rectangular section, and opposite sides of the second magnetic component 18 is formed in an arc shape to facilitate rotation, and at the same time, to be as close as possible to the first magnetic component 22. It should be understood that the shapes of the first and second magnetic components 22 and 18 are merely exemplary. In other embodiments, the first and second magnetic components 22 and 18 may be formed in other shapes.

[00127] In another embodiment, the male buckle 10 is provided with the first magnetic component 22 and the female buckle 20 is provided with the second magnetic component 18. That is, the second magnetic component 18 in the female buckle 20 is driven to rotate relative to the first magnetic component 22 in the male buckle 10 to change from mutual magnetic attraction to mutual magnetic repulsion.

[00128] Referring to FIGS. 4, 9, and 10, a moving direction of the engaging member 14 is an up-down direction in FIG. 4, and the mating direction of the male buckle 10 and the female buckle 20 is a left-right direction in FIG. 4, and a direction of a rotation axis of the second magnetic component 18 is the up-down direction in FIG. 4. That is, the moving direction of the engaging member 14 is perpendicular to the mating direction of the male buckle 10 and the female buckle 20, and is also perpendicular to a moving direction of the release button 12, and is parallel to the direction of the rotation axis of the second magnetic component 18.

[00129] The first magnetic component 22 is fixed and disposed on the female buckle 20, the second magnetic component 18 is rotatably disposed on the male buckle 10, such that only by aligning the male buckle 10 and the female buckle 20, the male buckle 10 and the female buckle 20 can be engaged by magnetically attracting the first magnetic component 22 with the second magnetic component 18 along the mating direction. Under the magnetic attraction effect of the first magnetic component 22 and the second magnetic component 18, the male buckle and the female buckle can be automatically engaged and is convenient to use. Meanwhile, when the buckle assembly 1 is released, the release button 12 may drive the second magnetic component 18 to rotate, such that the first magnetic component 22 and the second magnetic component 18 are magnetically repelled so that the male buckle 10 and the female buckle 20 are automatically separated. Therefore, the buckle assembly 1 of the present disclosure is easy to operate and convenient to use. [00130] A second embodiment of the present application will be described below. The following mainly describes different parts of the second embodiment from the first embodiment, and the same parts of the second embodiment from the first embodiment are omitted to avoid redundancy.

[00131] Referring to FIG. 12, the male buckle 10 includes two belt holes 114. The two belt holes 114 are formed on two attached portions 111, respectively. A belt (not shown) may be sequentially passed through the two belt holes 114 to provide the male buckle 10 on the belt. The belt may be, for example, a safety belt of a child safety seat, but the present disclosure is not limited thereto.

[00132] With continued reference to FIG. 12, the female buckle 20 includes two belt holes 215. The two belt holes 215 are formed on the two attached portions 211, respectively. Another belt (not shown) may be sequentially passed through the two belt holes 215 to provide the female buckle 20 on the belt. The belt may be, for example, a safety belt of a child safety seat, but the present disclosure is not limited thereto.

[00133] Referring to FIG. 13, the male buckle housing 11 includes a male buckle resilient sheet 115. The male buckle resilient sheet 115 is integrally formed with the male buckle lower cover 112, but the present disclosure is not limited thereto. In an alternative embodiment, the male buckle resilient sheet 115 and the male buckle lower cover 112 are formed independently from each other and fixed together. The male buckle resilient sheet 115 is located below the male buckle lower cover 112. The belt passing through the two belt holes 114 may pass through a gap between the male buckle resilient sheet 115 and the male buckle lower cover 112, and thus can be clamped by the male buckle resilient sheet 115 and the male buckle lower cover 112.

[00134] With continued reference to FIG. 13, the female buckle 20 has a female buckle lower cover 216. The female buckle lower cover 216 is detachably disposed at a lower portion of the female buckle 20, thereby facilitating installation and removal of components inside the female buckle 20. In an alternative embodiment, the female buckle lower cover 216 may constitute a part of the female buckle housing 21 and be fixedly connected to other parts of the female buckle housing 21. The female buckle housing 21 includes a female buckle resilient sheet 217. The female buckle resilient sheet 217 is integrally formed with the female buckle lower cover 216, but the present disclosure is not limited thereto. In an alternative embodiment, the female buckle resilient sheet 217 and the female buckle lower cover 216 are formed independently from each other and fixed together. The female buckle resilient sheet 217 is located below the female buckle lower cover 216. The belt passing through two belt holes 215 may pass through a gap between the female buckle resilient sheet 217 and the female buckle lower cover 216, and thus be clamped by the female buckle resilient sheet 217 and the female buckle lower cover 216.

[00135] Referring to FIGS. 14 and 15, the male buckle resilient sheet 115 includes an elastic deformable portion 1151 and a clamping portion 1152. The elastic deformable portion 1151 connects the clamping portion 1152 and the male buckle lower cover 112. The elastic deformable portion 1151 is connected to a side of the lower surface of the male buckle lower cover 112 away from the female buckle 20, but the present disclosure is not limited thereto. The elastic deformable portion 1151 may be elastically deformed to provide an elastic restoring force. As a specific example, the elastic deformable portion 1151 is a curved sheet, but the present disclosure is not limited thereto. A gap between the clamping portion 1152 and the male buckle lower cover 112 is less than a thickness of the belt passing through the two belt holes 114. As such, when the belt is inserted into the gap between the clamping portion 1152 and the male buckle lower cover 112, the gap is expanded by the belt (i.e., the clamping portion 1152 is pressed by the belt to move downward). The elastic deformable portion 1151 is elastically deformed due to movement of the clamping portion 1152, and keeps applying a clamping force (restoring force) to the belt. As such, the male buckle 10 may be securely clamped on the belt, such that the slippage and loosening of the belt are prevented.

[00136] With continued reference to FIGS. 14 and 15, the female buckle resilient sheet 217 includes an elastic deformable portion 2171 and a clamping portion 2172. The elastic deformable portion 2171 connects the clamping portion 2172 and the female buckle lower cover 216. The elastic deformable portion 2171 is connected to a side of the lower surface of the female buckle lower cover 216 away from the male buckle 10, but the present disclosure is not limited thereto. The elastic deformable portion 1151 may be elastically deformed to provide an elastic restoring force. As a specific example, the elastic deformable portion 2171 is a curved sheet, but the present application is not limited thereto. A gap between the clamping portion 2172 and the female buckle lower cover 216 is less than a thickness of the belt passing through the two belt holes 215. As such, when the belt is inserted into the gap between the clamping portion 2172 and the female buckle lower cover 216, the gap is expanded by the belt (i.e., the clamping portion 2172 is pressed by the belt to move downward). The elastic deformable portion 2171 is elastically deformed due to movement of the clamping portion 2172, and keeps applying a clamping force (restoring force) to the belt. As such, the female buckle 10 may be securely clamped on the belt, such that the slippage and loosening of the belt are prevented.

[00137] It should be understood that, in some embodiments, the buckle assembly 1 may have only the male buckle lower cover 112 and the male buckle resilient sheet 115, but do not have the female buckle lower cover 216 and the female buckle resilient sheet 217.

[00138] Alternatively, the buckle assembly 1 may have only the female buckle lower cover 216 and the female buckle resilient sheet 217, but do not have the male buckle lower cover 112 and the male buckle resilient sheet 115.

[00139] Referring to FIGS. 16 and 17, the female buckle lower cover 216 includes at least one positioning protrusion 2161. Specifically, the female buckle lower cover 216 includes four positioning protrusions 2161. The four positioning protrusions 2161 are disposed on four sides of the female buckle lower cover 216 respectively. For example, the four positioning protrusions 2161 are disposed on two sides of the female buckle lower cover 216 facing and facing away from the male buckle 10 and on two sides in the transverse direction respectively, but the present disclosure is not limited thereto. Correspondingly, the female buckle housing 21 includes at least one positioning recess 218. Specifically, the female buckle housing 21 includes four positioning recesses 218. The four positioning protrusions 2161 and the four positioning recesses 218 are in a one-to-one correspondence and fit each other, thereby fixing the female buckle lower cover 216 to the female buckle housing 21.

[00140] Alternatively, the female buckle lower cover 216 may include a positioning recess 218, and the female buckle housing 21 may include a positioning protrusion 2161.

[00141] Alternatively, the female buckle lower cover 216 may include other numbers of the positioning protrusions 2161, such as three, five, six, etc.

[00142] Alternatively, the female buckle housing 21 may include other numbers of the positioning recesses 218, such as three, five, six, etc.

[00143] In one embodiment, the number of the positioning protrusions 2161 is equal to that of the positioning recesses 218.

[00144] In another embodiment, the number of the positioning protrusions 2161 is not equal to that of the positioning recesses 218.

[00145] Referring to FIGS. 18 and 19, the lower male buckle cover 112 includes at least one positioning protrusion 1121. Specifically, the male buckle lower cover 112 includes five positioning protrusions 1121. The five positioning protrusions 1121 are disposed on three of four sides of the male buckle lower cover 112 respectively. For example, a side of the male buckle lower cover 112 away from the female buckle 20 is provided with one positioning protrusion 1121, and each of two lateral sides of the male buckle lower cover 112 is provided with two positioning protrusions 1121 respectively, but the present disclosure is not limited thereto. Correspondingly, 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 protrusions 1121 and the five positioning recesses 116 are in a one-to-one correspondence and fit each other, thereby fixing the male buckle lower cover 112 to the male buckle housing 11.

[00146] Alternatively, the male buckle lower cover 112 may include a positioning recess 116, and the male buckle housing 11 may include a positioning protrusion 1121.

[00147] Alternatively, the male buckle lower cover 112 may include other numbers of the positioning protrusions 1121, such as three, four, six, seven, etc.

[00148] Alternatively, the male buckle housing 11 may include other numbers of the positioning recesses 116, such as three, four, six, seven, etc.

[00149] In one embodiment, the number of the positioning protrusions 1121 is equal to that of the positioning recesses 116.

[00150] In another embodiment, the number of the positioning protrusions 1121 is not equal to that of the positioning recesses 116.

[00151] Referring to FIGS. 16 and 18, a length of the male buckle lower cover 112 is greater than that of the female buckle lower cover 216. Referring to FIG. 15, a part of the male buckle lower cover 112 extends into the female buckle 20. It should be understood that, since the length of the male buckle lower cover 112 is greater than that of the female buckle lower cover 216, the number of the positioning protrusions 1121 of the male buckle lower cover 112 may be greater than the number of the positioning protrusions 2161 of the female buckle lower cover 216.

[00152] By providing the male buckle resilient sheet 115 and/or the female buckle resilient sheet 217, the belt attached to the male buckle 10 and/or the female buckle 20 may be clamped, thereby preventing the safety belt from loosening, avoiding displacement of the male buckle 10 and/or the female buckle 20 relative to the safety belt, and improving safety and convenience of operation.

[00153] Other parts in the second embodiment may refer to the related description of the first embodiment. It should be understood that features in the second embodiment may be applied to the first embodiment and vice versa.

[00154] A third embodiment of the present application will be described below. The following mainly describes different parts of the third embodiment from the first embodiment, and the same parts of the third embodiment from the first embodiment are omitted to avoid redundancy.

[00155] Referring to FIGS. 20 to 23, the buckle assembly 1 may include a male buckle 10 and a female buckle 20 mated into each other. The release button 12 is movably disposed on the male buckle 10. The release button 12 is partially exposed from the top of the male buckle housing 11 and protrudes from the top of the male buckle housing 11. This allows a more convenient operation of the release button 12 without inserting a finger into the male buckle housing 11. In this embodiment, the attached portions 111 and 211 extend along a width direction (the left-right direction in FIG. 25) of the buckle assembly 1.

[00156] Referring to FIGS. 21 and 22, the female buckle 20 includes 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 a bottom surface of the female buckle housing 21. The engaging portion 212 is disposed on the mating guide portion 219. The engaging portion 212 is, as a specific example, formed as an engaging hole. The engaging hole has a substantially square shape. In this embodiment, the engaging portion 212 is formed by one engaging hole. In another embodiment, the engaging portion 212 may be formed by two or more engaging holes.

[00157] Referring to FIG. 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 is formed to have a tongue portion having a relatively flat shape. When the male buckle 10 is mated with the female buckle 20, the guide portion 113 contacts an upper surface of the mating guide portion 219, thereby guiding the mating of the male buckle 10 and the female buckle 20.

[00158] Referring to FIGS. 21 and 25, the female buckle 20 includes a first magnetic component holder 23. The female buckle housing 21 has an accommodation chamber 214 for receiving the first magnetic component 22. The accommodation chamber 214 is open to a bottom portion of the female buckle housing 21. The first magnetic component holder 23 is for engaging with the female buckle housing 21 to fix the first magnetic component 22 in the female buckle housing 21 (specifically, the accommodation chamber 214).

[00159] A positioning protrusion 231 is formed on the first magnetic component holder 23. Apositioning recess 2141 is formed on the female buckle housing 21. The positions of the positioning protrusion 231 and the positioning recess 2141 correspond to each other. The first magnetic component holder 23 is engaged with the female buckle housing 21 by mating of the positioning protrusion 231 with the positioning recess 2141. The number of the positioning protrusions 231 may be equal to that of the positioning recesses 2141, for example, the number of the positioning protrusions 231 and the number of the positioning recesses 2141 are two, four, eight, or other numbers respectively.

[00160] Referring to FIG. 24, in this embodiment, a part of the guide portion 113 is located above the first magnetic component 22 when the male buckle 10 is mated with the female buckle 20. The male buckle housing 11 includes a male buckle lower cover 112 and a male buckle upper cover 117 which are connected with each other. The male buckle lower cover 112 and the male buckle upper cover 117 are snap-fitted to each other, but the present disclosure is not limited thereto. The male buckle lower cover 112 has an accommodating hole 1123. The engaging member 14 is movably disposed in the accommodating hole 1123. The male buckle 10 includes a fixing seat 19. The fixing seat 19 is fixed at the accommodating hole 1123. Specifically, the fixing seat 19 covers an upper side of the accommodation hole 1123. The engaging member 14 is connected with the fixing seat 19 by the resilient member 15. That is, the engaging member 14 is attached to the fixing seat 19 by the resilient member 15. The fixing seat 19 has a connecting arm 191. The male buckle lower cover 112 has a slot 1122. The slot 1122 is located at periphery of the accommodating hole 1123. The connecting arm 191 of the fixing seat 19 is inserted into the slot 1122. An upper end of the fixing seat 19 abuts against the release button 12 to position the fixing seat 19. The fixing seat 19 may have two connecting arms 191, but the present disclosure is not limited thereto. The resilient member 15 is, for example, a helical spring, but the present disclosure is not limited thereto. When the resilient member 15 is in its resting state, the engaging member 14 partially protrudes out of the accommodating hole 1123. When the male buckle 10 is mated with the female buckle 20, the engaging member 14 enters into the engaging portion 212, thereby preventing the male buckle 10 and the female buckle 20 from moving in the lateral direction and/or the front-rear direction relative to each other (i.e., engaging the male buckle 10 and the female buckle 20 with each other). A lower surface of the engaging member 14 is formed as a first inclined surface, such that the engaging member 14 is driven to move into the accommodating hole 1123 by the abutment of the first inclined surface against the mating guide portion 219 when the male buckle 10 and the female buckle 20 are mated into each other, so as to avoid obstructing relative movement of the male buckle 10 and the female buckle 20. The first inclined surface is disposed towards a mating direction of the male buckle 10 and the female buckle 20, and has a guiding function. When the first inclined surface enters into the female buckle 20, the engaging member 14 can be driven to move into the accommodating hole 1123 by abutting against the inner wall of the mating guide portion 219, and the resilient member 15 is compressed. When the engaging member 14 is aligned with the engaging portion 212 in the thickness direction, the engaging member 14 partially protrudes out of the accommodating hole 1123 under a force exerted by the resilient member 15, and the engagement may be realized without pressing the release button 12.

[00161] Referring to FIG. 26, the engaging member 14 includes a driven rod 143, or the buckle assembly 1 includes the driven rod 143 disposed on the engaging member 14. The release button 12 includes a driving block 124, or buckle assembly 1 includes the driving block 124 connected with the release button 12. The driving block 124 has a second inclined surface 1241. The release button 12 drive the driven rod 143 to move by the second inclined surface 1241, thereby causing the engaging member 14 moving. The driving block 124 is movably located at a lower portion of the release button 12, and movement of the release button 12 causes the driving block 124 moving together with the release button 12. Specifically, when the buckle assembly 1 is released, the release button 12 is pushed in a direction of the arrow shown in FIG. 26, the release button 12 moves together with the driving block 124, and the second inclined surface 1241 of the driving member 124 pushes the driven rod 143, so as to drive the engaging member 14 to move upward (upward as shown in FIG. 24) to disengage from the engaging portion 212 (i.e., release the buckle assembly 1). At this time, the male buckle 10 and the female buckle 20 may be separated by moving in a direction away from each other.

[00162] Referring to FIG. 27 to 29, similar to the first embodiment, in this embodiment, the release button 12 includes an arm portion 123. The release button 12 may include two arm portions 123 parallel to each other. The rotary member 17 includes a gear 171. One of the two arm portions 123 has a rack 121 formed thereon. The gear 171 is meshed with the rack 121. A position of the driving block 124 in this embodiment is different from that of the first embodiment, and specifically, the driving block 124 in this embodiment is formed at a lower portion of the release button 12.

[00163] The release button 12 drives the engaging member 14 to release and the second magnetic component 18 to rotate simultaneously. Specifically, when the release button 12 drives the engaging member 14 to move upward to disengage from the engaging portion 212 as described above, the rack 121 on one of the two arm portions 123 of the release button 12 moves to cause the gear 171 meshed with the rack 121 rotating by about 180°, such that magnetic poles of the second magnetic component 18 on the rotary member 17 are reversed. As such, the first magnetic component 22 and the second magnetic component 18 would change from mutual magnetic attraction to mutual magnetic repulsion. After the engaging member 14 leaves the engaging portion 212, the magnetic repulsion force of the first magnetic component 22 against the second magnetic component 18 facilitates the separation of the male buckle 10 from the female buckle 20. That is, the male buckle 10 will automatically move out of the female buckle housing 21. When the release button 12 is no longer operated after the male buckle 10 is separated from the female buckle 20, the restoring member 13 will drive the release button 12 to return to the initial position, and in the meantime, the rack 121 on the release button 12 drives the gear 171 to rotate, thereby driving the second magnetic component 18 back to the initial position.

[00164] Referring to FIG. 28, the male buckle 10 is provided with one driving block 124 on each of left and right sides. The engaging member 14 is provided with one connecting arm 191 on each of front and rear sides. The fixing seat 19 may be stably fixed on the male buckle housing 11 by the connecting arm 191, and the restoring member 15 and the engaging member 14 are stably fixed in an accommodating space by the fixing seat 19, such that the engaging member 14 may stably perform engaging and releasing motions.

[00165] 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 at opposite sides of the male buckle 10 in the thickness direction (the up-down direction in FIG. 24), respectively. The release button 12 protrudes from the male buckle upper cover 117 to be operated, and the engaging member 14 protrudes from the male buckle lower cover 112 to be engaged with the female buckle 20.

[00166] In the third embodiment, the driving blocks 124 are disposed at opposite sides of the engaging member 14, such that the driving blocks 124 can drive the engaging member 14 to release better, and a size of the buckle assembly 1 can be reduced.

[00167] Other parts in the third embodiment may refer to the related description of the first embodiment. It should be understood that features in the third embodiment may be applied to the first embodiment and vice versa.
