Abstract

A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component, a second magnetic component and a clearance structure. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component. The clearance structure allows the second locking portion to slide an offsetting position for preventing the separation of the male buckling component and the female buckling component after engagement of the first locking portion and the second locking portion.

First claim

What is claimed is:

1. A magnetic buckling assembly comprising:
a male buckling component;
a female buckling component;
a first locking portion disposed on the female buckling component;
a second locking portion disposed on the male buckling component for engaging with the first locking portion;
an operating component movably disposed on the female buckling component;
a first magnetic component disposed on the female buckling component; and
a second magnetic component disposed on the male buckling component and for magnetically cooperating with the first magnetic component, wherein
the male buckling component is connected to the female buckling component along a connecting direction by engagement of the first locking portion and the second locking portion, the first magnetic component magnetically attracts or magnetically repulses the second magnetic component during a connecting process of the male buckling component and the female buckling component along the connecting direction, the first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component, one clearance structure is formed on the second locking portion for allowing the second locking portion to slide along an offsetting direction intersecting with the connecting direction to an offsetting position after the first locking portion engages with the second locking portion, and the female buckling component comprises an abutting portion for abutting against the second locking portion for preventing the separation of the male buckling component and the female buckling component when the second locking portion is located at the offsetting position, and
the female buckling component comprises an outer cover and a buckling body disposed inside the outer cover, the first locking portion is disposed on the buckling body, a connecting hole is formed on a side of the outer cover for allowing the second locking portion to pass therethrough, a second clearance structure is formed on the outer cover, the second clearance structure is a clearance hole communicated with the connecting hole, and the abutting portion is formed on the outer cover.

2. The magnetic buckling assembly of claim 1 , wherein the second locking portion comprises at least one first partition for engaging with the first locking portion and at least one second partition for abutting against the abutting portion, the clearance structure comprises a first clearance structure formed on the second locking portion, and the first clearance structure is a clearance slot.

3. The magnetic buckling assembly of claim 1 , wherein the lateral wall of the clearance slot abuts against an inner wall of the clearance hole when the second locking portion is located at the offsetting position.

4. The magnetic buckling assembly of claim 3 , wherein a contacting surface of the lateral wall of the clearance slot and a contacting surface of the inner wall of the clearance hole are flat surfaces.

5. The magnetic buckling assembly of claim 1 , wherein the connecting hole is arc-shaped hole, and the clearance hole is a rectangular hole and communicated with the arc-shape hole.

6. The magnetic buckling assembly of claim 1 , wherein the abutting portion is located on an inner surface of the outer cover adjacent to the inner wall of the clearance hole.

7. The magnetic buckling assembly of claim 1 , wherein a notch is formed on the buckling body and corresponding to the clearance hole, the notch is parallel to the connecting direction, the at least one second partition of the second locking portion slides into the notch during an offsetting process of the second locking portion.

8. The magnetic buckling assembly of claim 1 , wherein two clearance structures are formed on the second locking portion and opposite to each other.

9. A baby carrier, comprising two or more straps configured to be connected and disconnected by the male buckling component and the female buckling component of claim 1 .

10. The magnetic buckling assembly of claim 1 , wherein the second locking portion is a male locking portion, wherein the male buckling component includes a through hole for a strap, and wherein a plane normal to a longitudinal axis of the male locking portion passes through the through hole for the strap.

11. The magnetic buckling assembly of claim 1 , wherein the second locking portion is a male locking portion, and at least a part of the male locking portion envelopes a portion of the abutting portion when the second locking portion is located at the offsetting position.

12. The magnetic buckling assembly of claim 1 , wherein the female buckling component includes an opening at an outer surface of the female buckling component through which a portion of the male buckling component passes, the opening having a first partial-circular portion having a first diameter and a second portion which extends away from an extrapolated outer profile of the circle that establishes the first partial-circular portion, the second portion establishing the abutting portion.

13. The magnetic buckling assembly of claim 1 , wherein the outer cover of the female buckling component includes an opening at an outer surface of the outer cover of the female buckling component through which a portion of the male buckling component passes, the opening having a first partial-circular portion having a first diameter and a second portion which extends away from an extrapolated outer profile of the circle that establishes the first partial-circular portion, the second portion establishing the abutting portion.

14. The magnetic buckling assembly of claim 1 , wherein the male buckling component includes a main body to which the second locking portion is fixed, the female component includes a main body to which the first locking portion is movably attached, and the magnetic buckling assembly is configured so that during coupling of the male buckling component with the female buckling component, the second locking portion remains stationary relative to the main body of the male component and the first locking portion moves relative to the main body of the female component.

15. The magnetic buckling assembly of claim 1 , wherein the offsetting direction is normal to the connecting direction.

16. The magnetic buckling assembly of claim 1 , wherein the female buckling component includes an opening at an outer surface of the female buckling component through which a portion of the male buckling component passes, the opening having a curved shape first portion and a second portion which extends away from the first portion, the second portion establishing the abutting portion.

17. The magnetic buckling assembly of claim 1 , wherein the outer cover of the female buckling component includes an opening at an outer surface of the outer cover of the female buckling component through which a portion of the male buckling component passes, the opening having a curved shape first portion and a second portion which extends away from the first portion, the second portion establishing the abutting portion.
