Description

BUCKLE ASSEMBLY AND CHILD SAFETY SEATFIELD

[0001] Embodiments of the present disclosure relate to the art of child safety products, and particularly, to a magnetic buckle assembly.BACKGROUND

[0002] Child safety seats usually secure the child in the child safety seat through a five-point safety belt. To prevent children's shoulders from slipping out of the shoulder straps of the safety belts, some child safety seats are provided with chest buckles on the shoulder straps. The male and female buckles of the chest buckle are fixed to the two shoulder straps respectively. After the buckle of the five-point safety belt is fastened, the male and female buckles of the chest buckle are fastened. In this way, the child can be more safely fixed in the child safety seat.

The male buckle 10 and the female buckle 20 may be arranged opposite to each other along the Y direction (unless otherwise specified, the Y direction includes a positive Y direction and a negative Y direction, where the “positive Y direction” refers to the Y direction as shown in FIG. 1, and the “negative Y direction” refers to the direction opposite to the Y direction as shown in FIG. 1, and the same applies to the X direction and the Z direction). The female buckle 20 may include a first button 22 and a second button 23. In the present disclosure, the positive X direction may be referred to as the first direction, the positive Y direction may be referred to as the second direction, the positive Z direction may be referred to as the third direction, and the negative X direction may be referred to as the fourth direction, but the present disclosure is not limited thereto. The X direction, the Y direction, and the Z direction may be intersected with one another. Preferably, the X direction, the Y direction, and the Z direction may be perpendicular to one another.

[0123] The first button 22 and the second button 23 may be respectively located on opposite sides of the buckle assembly 1, wherein each of the opposite sides is facing the X direction. The first button 22 may be pressed along the positive X direction. The second button 23 may be pressed along the negative X direction. Two sides of the male buckle 10 facing the X direction may be respectively formed with a first connecting hole 111. Two sides of the female buckle 20 along the X direction may be respectively formed with a second connecting hole 211. The first connecting hole 111 and the second connecting hole 211 may extend laterally from the male buckle 10 and the female buckle 20, respectively. The first connecting hole 111 and the second connecting hole 211 may be used to connect, for example, a shoulder strap or a safety belt (not shown) of a child safety seat. In this embodiment, the first connecting hole 111 may be provided at the bottom of the male buckle 10, and the second connecting hole 211 may be provided at the bottom of the female buckle 20.

[0124] In some embodiments, the male button 10 may include the first button 22 and the secondbutton 23.

[0125] In some embodiments, the male buckle 10 may be formed with another number of first connecting hole(s) 111, such as one first connecting hole 111, which may be provided at an end of the male buckle 10 along the Y direction.

[0126] In some embodiments, the female buckle 20 may be formed with another number of second connecting hole(s) 211, such as one second connecting hole 211, which may be provided at an end of the female buckle 20 along the Y direction.

[0127] Referring to FIG. 3, the male buckle 10 may have a male buckle housing 11. The male buckle housing 11 may form at least a part of the appearance of the male buckle 10. The male buckle 10 may further include a mating portion 13. The mating portion 13 may protrude from the male buckle housing 11 in the Y direction. The mating portion 13 may be formed in a substantially flat plate shape, but the present disclosure is not limited thereto. The male buckle may further include a lock portion 12. The lock portion 12 may be connected to the mating portion 13. Alimiting rib 131 may be formed on the mating portion 13. The limiting rib 131 may be formed at the edge of the mating portion 13. The limiting rib 131 may include a first rib portion 1311 and a second rib portion 1312. The first rib portion 1311 may extend along the Y direction. The second rib portion 1312 may extend along the X direction. The first rib portion 1311 and the second rib portion 1312 may be formed integrally and perpendicular to each other. The mating portion 13 may have a surrounding hole 132 and a connecting arm 133. The lock portion 12 may be located in the surrounding hole 132 and connected to the mating portion 13 by the connecting arm 133. The surrounding hole 132 may surround most of the periphery of the mating portion 13. The surrounding hole 132 may be formed as a whole, or may be formed as a plurality of independent portions. The mating portion 13 may have one or more than one connecting arm 133, and the present disclosure does not limit the number of connecting arm(s) 133. A reinforcing portion 14 may be formed at the position where the mating portion 13 is connected to the male buckle housing 11, thereby strengthening the connection between the mating portion 13 and the male buckle housing 11 and preventing the mating portion 13 from being damaged by external forces. Reinforcing portions 14 may be formed on both sides of the position where the mating portion 13 is connected to the male buckle housing 11.

[0128] Referring to FIG. 4, for connecting, the male buckle 10 and the female buckle 20 may be brought together by approaching each other along the Z direction. In some embodiments, the male buckle 10 and the female buckle 20 may be brought together by approaching each other along the Y direction for connecting. The female buckle may include an engaging member 25. The engaging member 25 may be an iron piece, but the present disclosure is not limited thereto. The engaging member 25 may be engaged with the lock portion 12 to achieve the locking of the male buckle 10and the female buckle 20. The female buckle may include a limiting concave portion 212 (see FIGS. 4 and 5). The limiting concave portion 212 may be formed on the surface facing the male buckle 10. When the male buckle 10 is plugged into and mated with the female buckle 20, the limiting rib 131 may cooperate with the limiting concave portion 212 to limit the position of the male buckle 10 relative to the female buckle 20. That is, the cooperation of the limiting rib 131 and the limiting concave portion 212 can prevent the male buckle 10 and the female buckle 20 from moving relative to each other along the X direction and the Y direction. The limiting concave portion 212 may include a first concave portion 2121 that cooperates with the first rib portion 1311 and a second concave portion 2122 that cooperates with the second rib portion 1312.

[0129] Referring to FIG. 5 to FIG. 6, the lock portion 12 may include an engaging portion 121, a docking wall 122 and a body portion 124. The body portion 124 may be formed in a cylindrical shape, and a second magnet receiving portion 123 may be formed therein to receive a second magnet 40. The lower portion of the second magnet receiving portion 123 is open to facilitate placing the second magnet 40 therein. The second magnet 40 may be connected to or engaged with the male buckle 10 by means of an adhesive, or may be connected to the male buckle 10 by means of a positioning member. The engaging portion 121 may be formed on the periphery of the upper portion of the body portion 124. The engaging portion 121 may be formed to surround all or part of the periphery of the body portion 124. The periphery of the engaging portion 121 may be larger than the periphery of the body portion 124, so that the lower surface (facing the negative Z direction) of the engaging portion 121 may block the engaging member 25 from moving along the positive Z direction, thereby achieving locking between the male buckle 10 and the female buckle 20. The uppermost end of the engaging portion 121 may constitute the uppermost end of the lock portion 12. An inclined surface 1211 may be formed on the engaging portion 121. In some examples, the engaging portion 121 may be formed as a cone that gradually narrows from bottom to top (along the positive Z direction), and an inclined surface of the cone forms the inclined surface 1211, and the present disclosure is not limited thereto. The docking wall 122 may be formed on the inner side of the engaging portion 121 and is recessed relative to the engaging portion 121. The docking wall 122 may be at least partially surrounded by the engaging portion 121. When the male buckle 10 is plugged into and mated with the female buckle 20, the docking wall 122 is located between a first magnet 30 and the second magnet 40. The docking wall 122 may be formed as a plane.

[0130] The engaging member 25 may include a first engaging piece 251 and a second engaging piece 252. The first engaging piece 251 may be spaced apart from the second engaging piece 252 such that the distance between the first engaging piece 251 and the second engaging piece 252 is less than the outer diameter of the engaging portion 121. When the male buckle 10 is plugged into andmated with the female buckle 20, the inclined surface 1211 may press the first engaging piece 251 and the second engaging piece 252 of the engaging member 25 to deform the engaging member 25, so that the distance between the first engaging piece 251 and the second engaging piece 252 become greater than or equal to the outer diameter of the engaging portion 121, thereby allowing the lock portion 12 to pass through the gap between the first engaging piece 251 and the second engaging piece 252 to achieve locking.

[0131] Referring to FIG. 5 and FIG. 10, the female buckle 20 may include a sliding seat 26. The engaging member 25 may be provided on the sliding seat 26. The engaging member 25 may be fixedly connected to the sliding seat 26. Specifically, referring to FIG. 11, the engaging member 25 may include the first engaging piece 251, the second engaging piece 252, and a transverse portion 253 connected therebetween. At least a portion of the transverse portion 253 may be bent relative to the first engaging piece 251 and the second engaging piece 252. The transverse portion 253 may be engaged and fixed to the sliding seat 26 so that the engaging member 25 can slide with the sliding seat 26, and the present disclosure does not limit the manner through which the engaging member 25 is connected to the sliding seat 26. The engaging member 25 may be deformed or spread out when subjected to a force during the sliding process, specifically, the transverse portion 253 may be bent and deformed during the sliding process and the first engaging piece 251 and the second engaging piece 252 may be spread out when subjected to a force during the sliding process. The engaging member 25 may further include limiting pieces 254. The limiting piece 254 may be formed on the outer side of the first engaging piece 251 and the outer side of the second engaging piece 252 to define the minimum gap between the first engaging piece 251 and the second engaging piece 252. The sliding seat 26 is connected to the second button 23. A first magnet accommodating portion 261 and an engaging cavity 262 may be formed on the sliding seat 26. A first magnet 30 may be accommodated in the first magnet accommodating portion 261. The upper portion of the first magnet accommodating portion 261 is open to facilitate placing the first magnet 30 therein. A first cover 263 may be used to seal and position the first magnet 30 in the first magnet accommodating portion 261. The first cover 263 may be engaged in the first magnet accommodating portion 261 of sliding seat 26. The first cover 263 may be made of plastic. An engaging protrusion 2631 may be formed on the periphery of the first cover 263. The engaging protrusion 2631 may be formed as an annulus around the first cover 263, or may be formed as a plurality of parts separated from one another around the first cover 263. The first cover 263 may be mated with a corresponding concave portion on the female buckle 20 through the engaging protrusion 2631 to achieve a fixed connection. The engaging cavity 262 may be formed at the periphery of the lower portion of the first magnet accommodating portion 261. The engaging cavity 262 may accommodate the engaging portion 121, so that the radial innerportion of the engaging cavity 262 of the sliding seat 26 may abut against the docking wall 122 of the lock portion 12, so that the engaging portion 121 entering the engaging cavity 262 may surround a portion of the first magnet 30. The first magnet 30 and the second magnet 40 face to each other and attract each other, so that the male buckle 10 and the female buckle 20 can be automatically engaged and connected with each other under the attraction between the first magnet 30 and the second magnet 40. In other words, the attraction between the first magnet 30 and the second magnet 40 is large enough to cause the inclined surface 1211 of the lock portion 12 to press the engaging member 25 to deform. In another embodiment, the first magnet 30 and the second magnet 40 may repel each other.

[0132] Referring to FIG. 5 and FIG. 6, the female buckle 20 may include a female buckle housing 21. The female buckle housing 21 may form at least a portion of the appearance of the female buckle 20. The female buckle housing 21 may include a female buckle upper cover 215 and a female buckle lower cover 214 (see FIG. 10). The female buckle upper cover 215 may be fixedly connected to the female buckle lower cover 214 by means of screws, and the present disclosure is not limited thereto.

[0133] Referring to FIG. 10, the female buckle 20 may further include a blocking member 24. The blocking member 24 is operable to block the second button 23 from being actuated. The second button23 may have an abutment portion 231, and when the buckle assembly 1 is in a locked state, the abutment portion 231 of the second button 23 abuts against the blocking member 24, such that the second button 23 is blocked from being operated. In some embodiments not shown in the figures, the blocking member 24 may block the sliding seat 26 to block the second button 23 from being operated. In some embodiments, the first button 22 may have a first inclined surface 221. The blocking member24 may have a second inclined surface 241. The second inclined surface 241 is configured to cooperate with the first inclined surface 221 to cause the blocking member 24 to move along the Y direction. The female buckle lower cover 214 may have a lock hole 213, and the lock hole 213 may allow the lock portion 12 to be inserted therein.

[0134] Referring to FIG. 8 to FIG. 10, the first button 22 is configured to operably block the second button 23 from being actuated, for example, the first button 22 is configured to prevent the second button 23 from being actuated when not actuated. The second button 23 is configured to be actuated to disengage the male buckle 10 from the female buckle 20. The first button 22, the second button 23, the blocking member 24 and the sliding seat 26 may all be slidably provided on the female buckle housing 21. The first button 22 and the second button 23 may slide along the X direction. The blocking member 24 may slide along the Y direction.

[0135] When the first button 22 is actuated along the positive X direction, the first inclined surface 221 may abut against the second inclined surface 241 of the blocking member 24 to push the blocking member 24 to move along the Y direction and disengage from the abutment against the abutmentportion 231, thereby unblocking the second button 23. In some embodiments, specifically, the first inclined surface 221 may be formed on a side of the first button 22 close to the blocking member 24, for example, on a side of the first button 22 facing the Y direction. In some embodiments, a first reset member 50 may be provided between the first button 22 and the second button 23. The first reset member 50 applies a pushing force to the first button 22 and the second button 23 to move away from each other. Specifically, in the embodiment as shown in FIGS. 8 and 11, one end of the first reset member 50 may abut against the first button 22, and the other end of the first reset member 50 may abut against the sliding seat 26. Since the second button 23 slides with the sliding seat 26, the abutment of the first reset member 50 against the sliding seat 26 may also enable the sliding seat 26 to drive the second button 23 to reset. The first reset member 50 may apply a restoring force to the first button 22 that tends to return the first button 22 to an initial state in which the button 22 is not actuated. In some embodiments, a first stopper portion 222 may be provided on the first button 22. The first stopper portion 222 may be formed on a side of the first button 22, for example, a side of the first button 22 facing the Y direction. The first stopper portion 222 may abut against the female buckle housing 21 to limit the first button 22, thereby preventing the first button 22 from sliding outside of the female buckle housing 21 and separating from the female buckle housing 21.

[0136] In some embodiments, the female buckle lower cover 214 may have a positioning member 2141, and the blocking member 24 may have a limiting hole 243 (see FIGS. 8 to 10). The positioning member 2141 may be inserted into the limiting hole 243 of the blocking member 24, so as to limit the sliding range of the blocking member 24. In some embodiments, a second reset member 60 may be provided between the blocking member 24 and the female buckle housing 21. The second reset member 60 may apply a force to the blocking member 24 to move toward a position for blocking the second button 23. Specifically, in some embodiments, the blocking member 24 may have a receiving groove 245, the second reset member 60 may be provided between the female buckle lower cover 214 and the receiving groove 245. The abutment portion 231 may be formed on a side of the second button 23 close to the blocking member 24, for example, The abutment portion 231 may be formed on a side of the second button 23 facing the Y direction. When the blocking member 24 is not actuated by the first button 22, the blocking member 24 abuts against the abutment portion 231 to prevent the second button 23 from being actuated along the negative X direction. The second reset member 60 applies a restoring force to the blocking member 24 that tends to return the blocking member 24 to an initial position in which the blocking member 24 is not actuated by the first button 22. Optionally, a structure for guiding the blocking member 24 to slide may be provided on the female buckle lower cover 214.

[0137] The second button 23 may be actuated to drive the sliding seat 26 and the engaging member25 to move along the negative X direction. Referring to FIGS. 11 to 13, the first engaging piece 251 and the second engaging piece 252 of the engaging member 25 abut against the lock portion 12 during the movement and are elastically deformed. Specifically, the shape of the gap between the first engaging piece 251 and the second engaging piece 252 corresponds to the shape of the body portion 124 of the lock portion 12. The distance between the first engaging piece 251 and the second engaging piece 252 at the end along the positive X direction is smaller than the diameter of the body portion 124, so that when the second button 23 drives the sliding seat 26 and the engaging member 25 to move along the negative X direction, the first engaging piece 251 and the second engaging piece 252 are pressed by the body portion 124 and spread out.

[0138] The operations of the buckle assemblies 1 in some embodiments will be described below.

[0139] When the male buckle 10 and the female buckle 20 are made to connect to each other, the male buckle 10 and the female buckle 20 are brought close to each other along the Z direction at the position shown in FIG. 6. The lock portion 12 enters the female buckle housing 21 through the lock hole 213. Then, the first magnet 30 and the second magnet 40 attract each other to further bring the male buckle 10 and the female buckle 20 closer. At this time, referring to FIG. 5, the inclined surface 1211 of the engaging portion 121 pushes the first engaging piece 251 and the second engaging piece 252 radially outward to elastically deform the engaging member 25. After the engaging portion 121 passes through the engaging member 25, it enters the engaging cavity 262. Then, the first engaging piece 251 and the second engaging piece 252 are restored to a state where the engaging member 25 is not deformed. The first engaging piece 251 and the second engaging piece 252 restored to the state where the engaging member 25 is not deformed are located below the engaging portion 121, thereby locking the engaging portion 121 in the engaging cavity 262. As shown in FIG. 8, when the buckle assembly 1 is in the locked state, the blocking member 24 abuts against the abutment portion 231 of the second button 23, so the second button 24 cannot move and the male buckle 10 cannot be disengaged from the female buckle 20.

[0140] For opening, the first button 22 is first pressed along the X direction. The first inclined surface 221 of the first button 22 cooperates with the second inclined surface 241 of the blocking member 24 to push the blocking member 24 in the Y direction, so that the blocking member 24 is out of the abutment against the abutment portion 231 of the second button 23. Then, the second button 23 is pushed in the negative X direction to release the lock of buckle assembly 1. During the disengagement of the male buckle 10 and the female buckle 20, the movement of the second button 23 along the negative X direction drives the sliding seat 26 and the engaging member 25 to move. The body portion 124 of the lock portion 12 pushes against the first engaging piece 251 and the second engaging piece 252 to spread out the first engaging piece 251 and the second engaging piece252, such that the engaging member 25 is not aligned with the lock portion 12 in the Z direction, and the engaging member 25is disengaged from the lock portion 12. In this way, the engaging member 25 no longer prevents the engaging portion 121 from moving along the negative Z direction. At this time, the first magnet 30 is not aligned with the second magnet 40, so that the attraction between the first magnet 30 and the second magnet 40 is weakened. In other words, the second magnet 40 can move along with the sliding seat 26 away from the first magnet 30, so that the attraction between the first magnet 30 and the second magnet 40 is weakened. Finally, the male buckle 10 and the female buckle 20 can be separated from each other along the Z direction.

[0141] During the engagement of the male buckle 10 and the female buckle 20, the engaging portion 121 of the lock portion 12 approaches the engaging member 25 along the positive Z direction, and pushes the first engaging piece 251 and the second engaging piece 252 to open to achieve locking. During the disengagement of the male buckle 10 and the female buckle 20, the second button 23 drives the engaging member 25 to move along the negative X direction and away from the lock portion 12. It can be understood that in some embodiments, during the disengagement of the male buckle 10 and the female buckle 20, the first button 22 and the second button 23 may be pressed at the same time to achieve the disengagement .

[0142] Another embodiment of the present disclosure will be described below. The same parts of the embodiment as the above mentioned embodiments will be omitted to avoid repetition.

[0143] Referring to FIG. 14, in this embodiment, the first connecting holes 111 may be provided on the side walls of the male buckle 10, and the second connecting holes 211 may be provided on the side walls of the female buckle 20.

[0144] Referring to FIG. 16, the lock portion 12 may include the engaging portion 121, the docking wall 122, and the body portion 124. The body portion 124 may be formed in a cylindrical shape, and the second magnet accommodating portion 123 may be formed inside the body portion 124 to accommodate the second magnet 40. The lower portion of the second magnet accommodating portion 123 is open to facilitate placing the second magnet 40 therein. The second magnet 40 may be sealed in the lock portion 12 by means of a second cover 125 engaged with the lock portion 12. The second cover 125 may be made of plastic and fixedly connected to the male buckle 10 through concave- convex fitting.

[0145] A limiting rib 131 may be formed on the mating portion 13 of the male buckle 10. A limiting protrusion 216 may be formed on the female buckle 20. When the male buckle 10 is plugged into and mated with the female buckle 20, the limiting rib 131 cooperates with the limiting protrusion 216 to limit the position of the male buckle 10 relative to the female buckle 20. In other words, the cooperation between the limiting rib 131 and the limiting protrusion 216 can prevent the male buckle10 and the female buckle 20 from moving relative to each other along the X direction and the Y direction.

[0146] The body portion 124 may be formed with an engaging groove 127. The engaging groove 127 surrounds the body portion 124 and is configured to limit the first engaging piece 251 and the second engaging piece 252. The docking wall 122 is flush with the end of the engaging portion 121 facing the sliding seat 26.

[0147] The operations of the buckle assemblies 1 in some embodiments will be described below.

[0148] When the male buckle 10 and the female buckle 20 are made to connect to each other, the male buckle 10 and the female buckle 20 are brought close to each other along the Z direction. The lock portion 12 enters the female buckle housing 21 through the lock hole 213. The first magnet 30 and the second magnet 40 attract each other to bring the male buckle 10 and the female buckle 20 closer. At this time, the inclined surface 1211 of the engaging portion 121 pushes the first engaging piece 251 and the second engaging piece 252 radially outward. After the engaging portion 121 passes through the engaging member 25, it enters the engaging cavity 262. Then, the first engaging piece 251 and the second engaging piece 252 are restored to the state where the engaging member 25 is not deformed. The restored first engaging piece 251 and the second engaging piece 252 are engaged with the engaging groove 127 (as shown in FIG. 16), thereby locking the engaging portion 121 in the engaging cavity 262. When the buckle assembly 1 is in the locked state, the blocking member 24 abuts against the abutment portion 231 of the second button 23, so the second button 24cannot move and the make buckle 10 cannot be disengaged from the female buckle 20.

[0149] For opening, the first button 22 is first pressed along the X direction. The first inclined surface 221 of the first button 22 cooperates with the second inclined surface 241 of the blocking member 24 to push the blocking member 24 in the Y direction, so that the blocking member 24 is out of the abutment against the abutment portion 231 of the second button 23. Then, the second button 23 is pushed in the negative X direction to release the lock of buckle assembly 1. During the disengagement of the male buckle 10 and the female buckle 20, the movement of the second button 23 along the negative X direction drives the sliding seat 26 and the engaging member 25 to move. The body portion 124 of the lock portion 12 pushes against the first engaging piece 251 and the second engaging piece 252 to spread out the first engaging piece 251 and the second engaging piece 252, such that the engaging member 25 is not aligned with the lock portion 12 in the Z direction. In this way, the engaging member 25 is disengaged from the engaging groove 127 and no longer prevents the engaging portion 121 from moving along the negative Z direction. At this time, the first magnet 30 is not aligned with the second magnet 40, so that the attraction between the first magnet 30 and the second magnet 40 is weakened. Finally, the male buckle 10 and the female buckle 20 can beseparated from each other along the Z direction.

[0150] In general, the buckle assembly 1 of the present disclosure may include a male buckle 10 and a female buckle 20. The male buckle 10 and the female buckle 20 may be connected or separated. The female buckle 20 is provided with a first magnet 30, and the male buckle 10 is provided with a second magnet 40. The magnetic poles of the two magnets 30, 40 facing each other can be opposite, and for connecting the male buckle 10 and the female buckle 20, there is no need for manual engaging. The male buckle 10 and the female buckle 20 only need to be aligned to each other, and the two will be connected to each other under the attraction of the magnets.

After the inclined surface 121 S passes through the engaging member 25 S, the third engaging piece 252 IS and the fourth engaging piece 2522S return to the state in which they have not moved radially outward and extend into the engaging groove 122S, so that the second engaging member 252S and the lock portion 12S are engaged with each other. In some embodiments, the second engaging member 252S return to the undeformed state.

[0197] As shown in FIG. 24, when the buckle assembly IS is in the locked state, the blocking member 24S abuts against the abutment portion 231 S of the second button 23 S, so the second button 24S cannot move and the male buckle 10 and the female buckle 20cannot be disengaged from each other.

[0198] Referring to FIGS. 25, 26, 28 and 31, for opening, the first button 22S is first pressed inwardly along the X direction. The first inclined surface 221 S of the first button 22S cooperates with the second inclined surface 241 S of the blocking member 24S to push the blocking member 24S away from the first button 22S along the Y direction, such that the blocking member 24S is no longer abutting against the abutment portion 231 S of the second button 23 S. Then, the second button 23 S is pressed in the direction opposite to the moving direction of the first button 22S to disengage the male buckle 10 from the female buckle 20.

[0199] During the disengagement of the male buckle 10 and the female buckle 20, the movement of the second button 23 S toward the first button 22 along the X direction drives the first magnet 30S to move. The movement of the first magnet 30S causes the first magnet 30S and the second magnet 40S are shifted relative to each other along the X direction and no longer align with each other (i.e., staggered with each other), thereby eliminating or reducing the attraction between the first magnet 3 OS and the second magnet 40 S.

[0200] During the disengagement of the male buckle 10 and the female buckle 20 the movement of the second button 23 S toward the first button 22 along the X direction drives the sliding seat 26S to move. The movement of the sliding seat 26S causes the driving blocks 2514S on the first engaging piece 2511 S and the second engaging piece 2512S to move along the driving inclined surfaces 2641 S of the sliding seat 26S, and the first engaging piece 2511 S and the second engaging piece 2512S are spread outwardly (opened to opposite sides) so as to be disengaged from the engaging groove 122S.

[0201] During the disengagement of the male buckle 10 and the female buckle 20, the movement of the second button 23 S toward the first button 22 along the X direction drives the second engaging member 252S to move. The movement of the second engaging member 252S causes the third engaging piece 2521 S and the fourth engaging piece 2522S to be disengaged from the engaging groove 122S. Specifically, when the second button 23 S is actuated, the direction in which the first engaging piece 2511 S and the second engaging piece 2512S are disengaged from the engaging groove 122S intersects with the direction in which the third engaging piece 252 IS and the fourth engaging piece 2522S are disengaged from the engaging groove 122S. In this way, the first engaging piece 251 IS, the second engaging piece 2512S, the third engaging piece 2521 S and the fourth engaging piece 2522S are all disengaged from the engaging groove 122S, thereby disengaging the male buckle 10S and the female buckle 20S. Finally, the male buckle 10S and the female buckle 20S can be separated from each other along the Z direction.

[0202] After the disengagement is completed and the male buckle 10S and the female buckle 20S are separated from each other, the first button 22S and the second button 23 S may be released separately or simultaneously, and the first button 22 S and the second button 23 S are pushed to the unactuated position along the X direction, respectively. The second reset member 60S pushes the blocking member 24S to the position where the blocking member 24S is not actuated by the first button 22S along the Y direction, and again blocks the movement of the second button 23 along the X direction. During the process of the second button 23 S moving to the unactuated position, the sliding seat 26S, the second engaging member 252S and the first magnet 30S move to the initial position together with the second button 23 S. As the sliding seat 26S moves toward the initial position, the driving inclined surfaces 264 IS on the sliding seat 26S are gradually out of the abutment against the driving blocks 2514S on the first engaging piece 2511 S and the second engaging piece 2512S, so that the first engaging piece 2511 S and the second engaging piece 2512S return to a state that is not pushed under the action of their own elastic restoring force.

[0203] For closing, the first engaging piece 251 IS, the second engaging piece 2512S, the third engaging piece 252 IS and the fourth engaging piece 2522S extend into the lock hole 213 S for engagement with the lock portion 12S of the male buckle 10S. The first magnet 30S is aligned withthe lock hole 213S so that the first magnet 30S and the second magnet 40S are aligned and attract each other when the male buckle IOS and the female buckle 20S are plugged and mated with each other.

[0204] Another embodiment of the present disclosure will be described below.

[0205] Referring to FIG. 37 and FIG. 38, the female buckle 20S may include a first button 22S and a second button 23 S. The first button 22S and the second button 23 S may be partially exposed to the outside of the female buckle 20S. The first button 22S and the second button 23 S may be arranged on two sides of the female buckle 20S, wherein each of the sides is facing the X direction. In some embodiments, the first button 22S and the second button 23 S may be opposite to each other. The female buckle 20S may have a female buckle housing 21 S. The female buckle 20S may have an engaging member 25S. The engaging member 25S is configured to engage with the lock portion 12S (see FIG. 22) to achieve engagement between the male buckle 10S (see FIG. 22) and the female buckle 20S. The engaging member 25 S may be a metal piece, and the present disclosure is not limited thereto.

[0206] In a specific example, the engaging member 25 S of this embodiment may be regarded as an integral structure. That is, compared with the above mentioned embodiment, the engaging member 25 S of this embodiment may be regarded as that the first engaging member 25 IS and the second engaging member 252S in the above mentioned embodiment are formed integrally.

[0207] The female buckle 20S may include a sliding seat 26S. The sliding seat 26S is slidably provided on the female buckle housing 2 IS, and the second button 23 may be actuated to drive the sliding seat 26S to slide.

[0208] In some embodiments, the driving member 26S may move synchronously with the second button 23 S. A first reset member 50S may be provided between the first button 22S and a spring positioning portion 267S of the sliding seat 26S. The first reset member 50S applies a pushing force to the first button 22S and the sliding seat 26S to move away from each other. The first reset member 50S may be a coil spring, and the present disclosure is not limited thereto. The female buckle housing 21S may have a female buckle lower cover 214S and a female buckle upper cover 215S.

[0209] Referring to FIG. 38 and FIG. 39, the female buckle lower cover 214S may have a lock hole 213S. The lock hole 213S may allow the lock portion 12S to be inserted therein. The lock hole 213 S may be formed in a circular shape, but the present disclosure is not limited thereto.

[0210] The female buckle 20S may have inclined surfaces 2146S. When the engaging member 25S moves away from the lock portion 12S along the X direction with the sliding seat 26S, the inclined surfaces 2146S may drive the engaging pieces of the engaging member 25S to move away from the lock hole 213S along the Y direction to be disengaged from the lock portion 12S.

[0211] The female buckle 20S may have driving inclined grooves 2145S. Specifically, the female buckle lower cover 214S may have two driving inclined grooves 2145S, and the two driving inclined grooves 2145S are located on both sides of the lock hole 213 S. The driving inclined groove 2145S may have a shape approximately in a triangle, specifically, may have a shape of a right triangle, and the present disclosure is not limited thereto. The distance between the driving inclined groove 2145S and the center of the lock hole 213 S in the Y direction gradually increases along the moving direction of the sliding seat 26S (upward along the X direction as shown in FIG. 39).

[0212] Referring to FIG. 40, the engaging member 25 S may include only the second engaging member 252S. In other words, the engaging member 25S is formed by the second engaging member 252S, or the engaging member 25S is equivalent to the second engaging member 252S. The second engaging member 252S may be formed by bending a metal sheet. For example, the second engaging member 252S may be at least partially formed by a metal piece (e.g., an iron piece).

[0213] The second engaging member 252S is, for example, in an embracing structure. A side of the third engaging piece 2521 S and a side the fourth engaging piece 2522S close to each other may be formed in an arc shape so as to match the contour of the engaging groove 122S.

[0214] The second engaging member 252S may include the third engaging piece 2521 S, the fourth engaging piece 2522S, and a second transverse portion 2523S. The third engaging piece 2521S and the fourth engaging piece 2522S are symmetrically formed and located on both sides of the second engaging member 252S. One side of the third engaging piece 2521 S is connected to one side of the fourth engaging piece 2522S via the second transverse portion 2523 S. The second transverse portion 2523 S of the second engaging member 252S may abut against the top (the end along the X direction) of the sliding seat 26S, so that when the sliding seat 26S moves along the X direction, the driving member 26S pushes the second engaging member 252S to move synchronously along the X direction through the second transverse portion 2523 S. At least one of the third engaging piece 252 IS and the fourth engaging piece 2522S may be coated with plastic, so that when the third engaging piece 2521 S and / or the fourth engaging piece 2522S is in contact with the engaging groove 122S (see FIG. 22) of the lock portion 12S, it is quieter and produces less vibration.

[0215] This embodiment also differs from the above mentioned embodiment in that the engaging member 25S may be formed with driving protrusion portions 2525S. When the second button 23S is pressed to drive the engaging member 25 S to move along the X direction, the driving protrusion portions 2525S move along the inclined surfaces 2146S, thereby being pushed outward by the two inclined surfaces 2146S.

[0216] In some embodiments, the third engaging piece 252 IS and the fourth engaging piece may be formed with a driving protrusion portion 2525 S respectively. When the second engaging member252S moves away from the lock portion 12S along the X direction with the sliding seat 26S, the two inclined surfaces 2146S respectively drive the driving protrusion portions 2525S of the third engaging piece 2521 S and the fourth engaging piece 2522S to move away from each other along the Y direction, so that the third engaging piece 2521 S and the fourth engaging piece 2522S of the second engaging member 252S are spread outwardly. In other words, the second engaging member 252S is disengaged from the lock portion 12S along the X direction and the Y direction.

[0217] In some embodiments, the driving protrusion portions 2525 S are provided at the lower end of the second engaging member 252S (the end close to the second button 23 S along the X direction). Specifically, the two driving protrusion portions 2525 S may be arranged on the other side of the second engaging member 252S (the third engaging piece 2521 S and the fourth engaging piece 2522S) away from the second transverse portion 2523 S.

[0218] Specifically, the two driving protrusion portions 2525 S may be formed at a corner of the third engaging piece 2521 S and a corner of the fourth engaging piece 2522S, respectively. The driving protrusion portions 2525 S may be formed as cylindrical protrusions, but the present disclosure is not limited thereto.

[0219] The driving protrusion portions 2525 S on the third engaging piece 252 IS and the fourth engaging piece 2522S are respectively located in the two driving inclined grooves 2145S of the female buckle lower cover 214S. When the second button 23S is pressed to drive the sliding seat 26S to move along the X direction, the distance between the driving protrusion portions 2525 S on the third engaging piece 2521 S and the fourth engaging piece 2522S gradually increases, so that the third engaging piece 2521 S and the fourth engaging piece 2522S of the engaging member 25S is pushed toward opposite sides, wherein each of the sides is facing the Y direction, and spread out.

[0220] The third engaging piece 2521 S and the fourth engaging piece 2522S may respectively have a hook portion 2526S on the side away from the second transverse portion 2523 S. The hook portion 2526S may extend from the third engaging piece 2521 S or the fourth engaging piece 2522S and bend to form a shape similar to the letter "L". The sliding seat 26S may have two hook avoidance grooves 268S. The two hook portions 2526S may be respectively located in the hook avoidance grooves 268S to prevent the sliding seat 26S from blocking the movement of the third engaging piece 2521 S and the fourth engaging piece 2522S.The hook portion 2526S may be used for mold positioning. In some embodiments not shown, the hook portion 2526S may be omitted.

[0221] Referring to FIG. 37 and FIG. 39, the second engaging member 252S may be driven to be unlocked from the lock portion 12S. The second engaging member 252S is provided on the sliding seat 26S. The third engaging piece 2521 S and the fourth engaging piece 2522S of the second engaging member 252S may surround the lock portion 12S, thereby locking with the lock portion 12S.

[0222] In some embodiments, the female buckle 20S has only one engaging member (the second engaging member 252S), which surrounds the portion with maximum diameter of the lock portion 12S of the male buckle 10S. For the second engaging member 252S moving along the X direction to disengage from the lock portion 12S, the lower end of the second engaging member 252S must pass over the portion with maximum diameter. If the lower end of the second engaging member 252S (the end close to the second button 23 S along the X direction) cannot be opened, it is difficult for the second engaging member 252S to move away and disengage from the lock portion 12S. Therefore, the embodiment uses only one engaging member to ensure that the male buckle 10S and the female buckle 20S are stably and reliably engaged to each other. During the process of disengagement, when the second engaging member 252S is able to move along the X direction with the sliding seat 26S, the third engaging piece 2521 S and the fourth engaging piece 2522S are pushed open by actuation of the two driving inclined grooves 2145S provided on the female buckle lower cover 214S, thereby realizing the rapid and reliable unlocking of the male buckle 10S and the female buckle 20S.

[0223] The operation processes of the buckle assemblies 100S in some embodiments will be described below.

[0224] Referring to FIG. 37 and FIG. 39, when the male buckle 10S and the female buckle 20S are connected with each other, the male buckle 10S and the female buckle 20S are brought close to each other along the Z direction (referring to FIG. 21 A, FIG. 21B and FIG. 24). The lock portion 12S enters the female buckle housing 21 S through the lock hole 213 S. The first magnet 30S and the second magnet 40S attract each other to bring the male buckle 10S and the female buckle 20S closer (referring to FIG. 23). At this time, the inclined surface 121 S of the lock portion 12S pushes the third engaging piece 252 IS and the fourth engaging piece 2522S radially outward to move. After the inclined surface 121 S passes through the engaging member 25S, the third engaging piece 2521 S and the fourth engaging piece 2522S return to a state where they have not moved radially outward and extend into the engaging groove 122S, so that the engaging member 25S and the lock portion 12S are engaged with each other. In some embodiments, the second engaging member 252S returns to an undeformed state.

[0225] For opening, the first button 22S is first pressed inwardly along the X direction. The first inclined surface 22 IS of the first button 22S cooperates with the second inclined surface 24 IS of the blocking member 24S to push the blocking member 24S away from the first button 22S along the Y direction, so that the blocking member 24S is out of the abutment against the abutment portion 231 S of the second button 23 S (referring to FIG. 24 and FIG. 25). Then, the second button 23 S is pressed in the direction opposite to the moving direction of the first button 22S. When the second button 23 S moves in the X direction, the second button 23 S pushes the sliding seat 26S and the sliding seat 26Smoves along the X direction with the second button 23 S. The movement of the sliding seat 26S makes the second engaging member 252S move away from the lock portion 12S along the X direction by pushing the second transverse portion 2523 S. The movement of the second engaging member 252S causes the third engaging piece 252 IS and the fourth engaging piece 2522S to move away from the engaging groove 122S along the X direction. At the same time, the two driving protrusion portions 2525S move along the inclined surfaces 2146S of the two driving inclined grooves 2145S, and are pushed outward by the two inclined surfaces 2146S, so that the third engaging piece 2521 S and the fourth engaging piece 2522S are pushed outward along the Y direction and away from the engaging groove 122S. In other words, when the second button 23S is actuated, the third engaging piece 2521S and the fourth engaging piece 2522S are moved away from the engaging groove 122S in both the X direction and the Y direction. Finally, the male buckle IOS and the female buckle 20S can be separated from each other along the Z direction.

[0226] During the operation of disengagement, the first button 22S and the second button 23 S may be pressed simultaneously to release the lock, thereby reducing the time required for the operation of releasing the lock and facilitating the operation of the user.

[0227] For other contents of this embodiment, reference may be made to the relevant description of the above mentioned embodiment.

[0228] In the present disclosure, the X direction, the Y direction and the Z direction may intersect with one another. Preferably, the X direction (first direction), the Y direction (second direction) and the Z direction (third direction) may be perpendicular with one another.

[0229] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the description and practicing the invention disclosed herein. The present disclosure is intended to cover any modification, use or adaptation of the present disclosure, which follows the general principles of the present disclosure and includes common knowledge or customary techniques in the art that are not disclosed in the present disclosure.
