Abstract

A magnetic buckle assembly includes first buckle component, a second buckle component for mating with the first buckle component, a switch movably disposed on the second buckle component, an operating component slidably disposed on the second buckle component and for driving the switch to move. The first magnetic component, a first magnetic component disposed on the first buckle component, a second magnetic component disposed on the switch and for magnetically attracting or repelling the first magnetic component, and a latch movably disposed on the second buckle component and for engaging with the first buckle component. The latch moves along with sliding movement of the operating component. The operating component drives the switch to move to change a direction of a magnetic force of the second magnetic component acting on the first magnetic component when the operating component is operated to slide to disengage the latch from the first buckle component.

First claim

What is claimed is:

1. A magnetic buckle assembly comprising:
a first buckle component;
a second buckle component for mating with the first buckle component;

a first magnetic component disposed on the first buckle component;
a second magnetic component disposed on the switch and for magnetically attracting or repelling the first magnetic component; and
a latch movably disposed on the second buckle component and for engaging with the first buckle component;
wherein the operating component drives the switch to change a direction of a magnetic force of the second magnetic component acting on the first magnetic component when the operating component is operated to disengage the latch from the first buckle component.

2. The magnetic buckle assembly of claim 1 , wherein the switch is rotatably disposed on the second buckle component around a rotating axis, the operating component drives the switch to rotate around the rotating axis when the operating component is operated to slide, and the second magnetic component rotates along with rotating movement of the switch.

3. The magnetic buckle assembly of claim 2 , wherein a driving structure is formed on the operating component, a driven structure is formed on the switch, and the operating component drives the switch to rotate around the rotating axis by cooperation of the driving structure and the driven structure.

4. The magnetic buckle assembly of claim 3 , wherein the driving structure is a gear rack structure arranged along a sliding direction of the operating component, and the driven structure is a gear wheel structure for rotatably engaging with the gear rack structure.

5. The magnetic buckle assembly of claim 2 , wherein an arranging direction of a rotating axis of the switch is parallel to a moving direction of the latch.

6. The magnetic buckle assembly of claim 2 , wherein an arranging direction of a rotating axis of the switch intersects with a sliding direction of the operating component and a mating direction of the first buckle component and the second buckle component.

7. The magnetic buckle assembly of claim 2 , wherein an arranging direction of a rotating axis of the switch is parallel to a front-rear direction of the magnetic buckle assembly.

8. The magnetic buckle assembly of claim 1 , wherein a hollow structure is formed on the switch, and the second magnetic component is disposed in the hollow structure.

9. The magnetic buckle assembly of claim 1 , wherein the switch is fixedly connected to the operating component, the operating component drives the switch to slide when the operating component is operated to slide, and the second magnetic component slides along with sliding movement of the switch.

10. The magnetic buckle assembly of claim 9 , wherein the second magnetic component comprises a first magnetic part and a second magnetic part, the first magnetic part and the second magnetic part are disposed on the switch and respectively for magnetically attracting the first magnetic component and magnetically repelling the first magnetic component.

11. The magnetic buckle assembly of claim 10 , wherein a first chamber and a second chamber are formed on the switch, and the first magnetic part and the second magnetic part are respectively disposed in the first chamber and the second chamber.

12. The magnetic buckle assembly of claim 1 , wherein a sliding direction of the operating component intersects with a moving direction of the latch and a mating direction of the first buckle component and the second buckle component.

13. The magnetic buckle assembly of claim 1 , wherein a direction of a magnetic force of the second magnetic component acting on the first magnetic component is parallel to a lateral direction of the magnetic buckle assembly.

14. The magnetic buckle assembly of claim 1 , wherein a driven cooperating structure is formed on the latch, a driving cooperating structure is formed on the operating component, the operating component drives the latch to move by cooperation of the driving cooperating structure and the driven cooperating structure, so as to disengage the latch from the first buckle component.

15. The magnetic buckle assembly of claim 14 , wherein the driving cooperating structure is a first inclined surface structure formed on the operating component and inclined relative to a moving direction of the latch, and the driven cooperating structure is a second inclined surface structure.

16. The magnetic buckle assembly of claim 1 , wherein a locking structure is formed on the latch, and a locked structure is formed on the first buckle component and for cooperating with the locking structure, and the latch is disengaged from the first buckle component by disengagement of the locking structure and the locked structure.

17. The magnetic buckle assembly of claim 1 , further comprising a first resilient component disposed between the operating component and the second buckle component.

18. The magnetic buckle assembly of claim 1 , further comprising a second resilient component disposed between the latch and the second buckle component.

19. The magnetic buckle assembly of claim 1 , wherein a mating direction of the first buckle component and the second buckle component is parallel to a lateral direction of the magnetic buckle assembly.

20. The magnetic buckle assembly of claim 1 , wherein the first buckle component is a male buckle, and the second buckle component is a female buckle, the first buckle component comprises a shoulder strap buckle and a waist strap buckle integrated with the shoulder strap buckle, and the second buckle component is a crotch strap buckle.
