Buckle assembly

Abstract

A buckle assembly including a first assembly and a second assembly is provided. The first assembly includes a first cover body, a pair of sliders, and a pair of first magnetic elements. The second assembly includes a second cover body and a pair of second magnetic elements. The first cover body includes an upper cover and a lower cover. The upper cover has a first fitting structure and a pair of first receiving grooves. The sliders are movably disposed in the first receiving grooves along a first direction. The first magnetic elements are embedded in the sliders, and the lower cover is assembled to the upper cover to limit the sliders and the first magnetic elements in the first receiving grooves. The second cover body has a second fitting structure and a pair of second receiving grooves.

What is claimed is: 
     
         1 . A buckle assembly, comprising:
 a first assembly, comprising:
 a first cover body, comprising an upper cover and a lower cover, and the upper cover having a first fitting structure and a pair of first receiving grooves; 
 a pair of sliders, movably disposed in the pair of first receiving grooves along a first direction; and 
 a pair of first magnetic elements, embedded in the pair of sliders, the lower cover assembled to the upper cover to cover up the first fitting structure and the pair of first receiving grooves to limit the pair of sliders and the pair of first magnetic elements in the pair of first receiving grooves; 
   a second assembly, comprising:
 a second cover body, having a second fitting structure and a pair of second receiving grooves, and the pair of second receiving grooves located on opposite sides of the second fitting structure; and 
 a pair of second magnetic elements, disposed in the pair of second receiving grooves, wherein when the first cover body and the second cover body are engaged with each other along a second direction perpendicular to the first direction, the pair of first magnetic elements and the pair of second magnetic elements are magnetically attracted to each other so that the pair of sliders move to a limiting position in the pair of first receiving grooves. 
   
     
     
         2 . The buckle assembly according to  claim 1 , wherein the first fitting structure is a convex structure protruding from a first surface of the upper cover, and the pair of first receiving grooves are formed in the first fitting structure, and the second fitting structure is a hole. 
     
     
         3 . The buckle assembly according to  claim 1 , wherein the first fitting structure further has a pair of limiting openings, and opening directions of the pair of limiting openings are opposite, and the second cover body further has a pair of limiting edges, wherein when the pair of sliders move to the limiting position in the pair of first receiving grooves, each of the sliders has a portion protruding from the pair of limiting openings, and the portion is limited by the pair of limiting edges in a reverse direction of the second direction. 
     
     
         4 . The buckle assembly according to  claim 3 , wherein the second cover body further has a guiding channel disposed along a third direction, the third direction is perpendicular to the first direction and the second direction, and the guiding channel has a necking portion along the third direction. 
     
     
         5 . The buckle assembly according to  claim 4 , wherein when the first assembly and the second assembly move relative to each other in the third direction, the pair of first magnetic elements and the pair of second magnetic elements move away from each other to release magnetic attraction, and the portion of each of the sliders protruding from the pair of limiting openings is guided by the necking portion and moves into the pair of first receiving grooves. 
     
     
         6 . The buckle assembly according to  claim 4 , wherein the second cover body further has a second surface and a sloping rib, the sloping rib and the second fitting structure are disposed on the second surface and extend in the third direction. 
     
     
         7 . The buckle assembly according to  claim 1 , wherein an N pole of one of the pair of first magnetic elements faces an S pole of the other first magnetic element. 
     
     
         8 . The buckle assembly according to  claim 7 , wherein magnetic attracting force of the pair of second magnetic elements is greater than magnetic attracting force of the pair of first magnetic elements. 
     
     
         9 . The buckle assembly according to  claim 8 , wherein the magnetic attracting force of at least one pair of the pair of first magnetic elements and the pair of second magnetic elements is adjusted by changing magnetic force of individual magnets, or relative positions and sizes of the two magnets.
