Of course, the core is not limited to being formed of the above materials.

Different embodiments of the magnetic snap 30, 30a, 30b according to the present invention will be described with reference to fig. 6-18.

First, referring to fig. 1, 6 to 7, the magnetic buckle 30 of the first embodiment includes a male buckle 31, a female buckle 32, and a lock release operation member 33, wherein the male buckle 31 is connected to the upper end of the vest 20, the female buckle 32 is connected to the shoulder straps 12, the lock release operation member 33 is movably disposed on the male buckle 31, the vest 20 is connected to the shoulder straps 12 by inserting the male buckle 31 into the female buckle 32, and the male buckle 31 and the female buckle 32 can be released by operating the lock release operation member 33. Understandably, the positions of the male buckle 31 and the female buckle 32 can be interchanged.

With continued reference to fig. 6-9, the magnetic buckle 30 further includes a first magnetic attraction structure 34 and a second magnetic attraction structure 35 that are magnetically attracted to each other. The male snap 31 has a locking portion 31a, and the female snap 32 has a mating locking portion 32a for mating with the locking portion 31 a. The first magnetic attraction structure 34 is disposed on the male buckle 31, and the second magnetic attraction structure 35 is disposed on the female buckle 32. The male buckle 31 and the female buckle 32 are inserted into each other along a direction close to each other, so that the locking portion 31a and the insertion locking portion 32a are locked, and the first magnetic attraction structure 34 and the second magnetic attraction structure 35 are magnetically attracted to each other in the insertion process, so that the male buckle 31 and the female buckle 32 are buckled more quickly. When the release operation member 33 selectively releases the lock between the lock portion 31a and the opposite insertion lock portion 32a to allow the male buckle 31 and the female buckle 32 to be pulled out from each other, the first magnetic attraction structure 34 and the second magnetic attraction structure 35 at this time magnetically attract each other to keep the male buckle 31 and the female buckle 32 in the opposite insertion state. Of course, in other embodiments, the first magnetic attraction structure 34 disposed on the male buckle 31 and the second magnetic attraction structure 35 disposed on the female buckle 32 can also be magnetically repelled, so that the first magnetic attraction structure 34 and the second magnetic attraction structure 35 are magnetically repelled to keep the locked locking portion 31a and the opposite-insertion locking portion 32a in an abutting state, and the locking is more reliable, and the above-mentioned example is not limited.

Specifically, the magnetic buckle 30 of the present embodiment further includes an outer cover 36, the male buckle 31 is disposed in the outer cover 36, and the lock releasing operation member 33 is movably disposed on the outer cover 36 along the inserting direction (the up-down direction shown in fig. 9), and preferably, the lock releasing operation member 33 is a circular button, so that the user can press the lock releasing operation member 33 to mutually lock the locking portion 31a and the inserting locking portion 32 a. The outer cover 36 has a through hole 361 for passing the lock releasing operation member 33 at one end in the opposite insertion direction (e.g., the upper end of the outer cover 36 in fig. 9), and the outer cover 36 has an opposite insertion hole 362 for inserting the lock part 32a in the opposite insertion direction (e.g., the lower end of the outer cover 36 in fig. 9), so that the outer cover 36 makes the male buckle 31 and the female buckle 32 more stable in operation, and simultaneously blocks dust, reduces the wear of the male buckle 31 and the female buckle 32 caused by the outside, correspondingly prolongs the service life of the magnetic buckle 30, and is more elegant.

It is understood that, in other embodiments, the opposite insertion locking portion 32a may be formed on the male buckle 31, and the locking portion 31a may be formed on the female buckle 32; when the locking portion 31a is formed on the female buckle 32, the lock release operation member 33 is correspondingly provided on the female buckle 32, and the outer cover 36 can be deleted according to actual needs, so that the above-mentioned example is not limited.

Referring to fig. 8-9, the locking portion 31a is an elastic structure, and the opposite-insertion locking portion 32a has a pushing structure 321 and a locking structure 322. In the process of inserting, the pushing structure 321 pushes the locking portion 31a to elastically deform the locking portion 31a, so that the locking portion 31a slides to a position locked with the locking structure 322, which is shown in fig. 9; the release operation member 33 selectively urges the locking portion 31a to be elastically deformed out of locking with the locking structure 322. Therefore, the pushing structure 321 makes the locking structure 322 lock with the locking portion 31a more quickly and smoothly.

Specifically, as shown in fig. 9, the locking portion 31a includes a resilient arm 311 and a lock head 312 for locking with the locking structure 322, and the lock head 312 is connected to the resilient arm 311, preferably, the resilient arm 311 and the lock head 312 together form an integral structure, so that the lock head 312 is suspended at the middle of the pin 31 by the resilient arm 311, as shown in fig. 9, so that the resilient arm 311 more reliably drives the lock head 312 to move. The elastic arm 311 always has a tendency of driving the lock head 312 and the lock matching structure 322 to be locked with each other; therefore, in the inserting process, the pushing structure 321 drives the elastic arm 311 to generate elastic deformation by pushing the lock head 312, so that the lock head 312 slides to the position locked with the locking structure 322, thereby achieving the purpose of automatically locking the male buckle 31 and the female buckle 32 in the inserting process. The release operation member 33 selectively drives the elastic arm 311 to elastically deform, so that the lock head 312 is separated from the lock matching structure 322, preferably, the release operation member 33 pushes the elastic arm 311 in a direction parallel to the opposite insertion direction, so that the elastic arm 311 elastically deforms in a direction crossing the opposite insertion direction to separate the lock head 312 from the lock matching structure 322, so that the lock releasing process between the lock head 312 and the lock matching structure 322 is simple.

In this embodiment, the two elastic arms 311 are arranged to embrace the opposite insertion locking portions 32a, and each elastic arm 311 is connected with the lock head 312, so that the lock head 312 surrounds the opposite insertion locking portions 322, and the lock head 312 is more reliably locked with the opposite insertion locking portions 322, thereby the male buckle 31 and the female buckle 32 are more stably and reliably buckled. Of course, in other embodiments, the number of the elastic arms 311 may also be three, four or five, and is not limited thereto. Preferably, the lock head 312 is a hook-shaped structure, and the locking structure 322 is a hook slot, so that the magnetic buckle 30 of the present embodiment is fastened more tightly and is not easy to disengage by the cooperation of the hook-shaped structure and the hook slot. Meanwhile, the male buckle 31 is a hollow structure, the middle part of the male buckle 31 is provided with a transverse middle supporting arm 314 (see fig. 8 and 10), and the middle supporting arm 314 is located between the two elastic arms 311 and connected to the corresponding two side walls of the male buckle 31, so as to increase the strength of the male buckle 31.

Referring to fig. 8 to 11, the end of the pushing structure 321 has a first inclined structure 3211 inclined with respect to the opposite insertion direction (the up-down direction shown in fig. 9), and the locking head 312 has a second inclined structure 3121 matching with the first inclined structure 3211; in the inserting process, the pushing structure 321 easily goes over the lock head 312 by pushing the second inclined structure 3121 by the first inclined structure 3211, and the pushing structure 321 slides to the position where the lock structure 322 and the lock head 312 are locked, so as to facilitate the locking of the pin 31 and the box 32.

With reference to fig. 8 to 11, the releasing operation member 33 has a pushing inclined surface 331 inclined with respect to the opposite insertion direction, and the releasing operation member 33 pushes the elastic arm 311 to generate elastic deformation by the pushing inclined surface 331 so as to disengage the lock head 312 from the lock matching structure 322 for releasing the lock. Because the lock head 312 is disposed around the lock matching structure 322, the pushing inclined plane 331 is inclined from inside to outside along the direction away from the pushing structure 321, and the lock releasing operation member 33 pushes the elastic arm 311 to perform the expanding elastic deformation by the pushing inclined plane 331, so that the elastic arm 311 drives the lock head 312 to be separated from the lock matching structure 322. Of course, in other embodiments, the elastic arm 311 may also drive the locking head 312 to disengage from the locking structure 322, so the invention is not limited thereto. For example, in the present embodiment, the unlocking operation member 33 extends outward to form the spreading leg 332 in a direction parallel to the inserting direction, and the pushing inclined surface 331 is formed on the spreading leg 332. One end of the elastic arm 311, which is used for being connected with the lock head 312, is provided with a pushed inclined surface 3111 matched with the pushing inclined surface 331, and the lock releasing operation piece 33 pushes the elastic arm 311 to generate elastic deformation by the matching of the pushing inclined surface 331 and the pushed inclined surface 3111 so as to separate the lock head 312 from the lock matching structure 21; preferably, the end of the elastic arm 311 connected to the lock head 312 is provided with a groove 3112, the propping leg 332 extends into the groove 3112, the pushed inclined surface 3111 is formed on the wall surface of the groove 3112, and the propping inclined surface 331 is formed on the end surface of the propping leg 332, so that the structure that the lock releasing operation part 33 props the elastic arm 311 to generate elastic deformation is simpler, the propping leg 332 directly acts on the groove 3112 at the end connected to the lock head 312 to further accelerate the elastic deformation of the elastic arm 311, and the lock head 312 and the lock matching structure 322 are separated more quickly, and thus the invention is not limited thereto.

Referring to fig. 8, 9 and 11, the male buckle 31 has a first embedding cavity 313, the female buckle 32 has a second embedding cavity 323, the first magnetic attraction structure 34 is embedded in the first embedding cavity 313, and the second magnetic attraction structure 35 is embedded in the second embedding cavity 323, so that the first magnetic attraction structure 34 is hidden in the male buckle 31, and the second magnetic attraction structure 35 is hidden in the female buckle 32. Specifically, the first embedding cavity 313 is aligned with the second embedding cavity 323 along the opposite insertion direction, so as to maximize the magnetic acting force between the first magnetic attraction structure 34 and the second magnetic attraction structure 35, so as to make the opposite insertion between the male buckle 31 and the female buckle 32 faster, and meanwhile, to maintain a maximum magnetic attraction force between the inserted male buckle 31 and the female buckle 32, thereby effectively preventing the accidental separation between the male buckle 31 and the female buckle 32. For example, the second embedding cavity 323 is formed in the opposite insertion locking portion 32a (see fig. 9), and the first embedding cavity 313 is formed at the middle portion of the male buckle 31, specifically, at the middle portion of the middle support arm 314, so that the magnetic buckle 30 of the present invention has reasonable space utilization and material saving. Meanwhile, the first magnetic attraction structure 34 and the second magnetic attraction structure 35 are magnets respectively; of course, in other embodiments, one of the first magnetic attraction structure 34 and the second magnetic attraction structure 35 is a magnet, and the other is a metal structure, so it is not limited thereto; preferably, the thickness of the first magnetic attraction structure 34 is in a range of 3.0 to 5.5 mm, preferably 3.0, 3.8, 4.5, 5.0 or 5.5 mm. Note that, when the mating lock portion 32a is formed on the male buckle 31, the first insertion cavity 313 is formed in the mating lock portion 32 a.

As shown in fig. 1, 6-8 and 10, the female buckle 32 and the outer cover 36 each have an assembling end for assembling a woven belt. Preferably, the two assembling ends of the female buckle 32 are oppositely arranged, and the one assembling end of the outer cover 36 is always arranged back to back with any assembling end of the female buckle 32, so as to facilitate the assembling of the woven belt. For example, two ends of the female buckle 32 are respectively provided with a through hole 324, and the female buckle 32 is fixed on the shoulder strap 12 by a weaving band passing through at least one through hole 324; correspondingly, a through hole 363 is formed at the assembling end of the outer cover 36, and the male buckle 31 is connected to the woven belt fixed at the upper end of the vest 20 through the through hole 363 of the outer cover 36.

In other embodiments, the opposite-insertion locking portion 32a has a cylindrical structure, so that the male buckle 31 and the female buckle 32 can selectively rotate around the opposite-insertion locking portion 32a, thereby making the work of the male buckle 31 and the female buckle 32 more flexible, and simultaneously making any one of the assembling ends on the female buckle 32 can be used with the assembling end on the outer cover 36 after rotating. When one of the assembling ends of the female buckle 32 is damaged, the other assembling end is matched with the assembling end of the outer cover 36 for use by rotating the female buckle 32, so that the magnetic buckle 30 of the invention is durable.

The operation principle of the magnetic buckle 30 according to the first embodiment of the present invention will be described with reference to fig. 6 to 11.

When the male buckle 31 is to be separated from the female buckle 32, the magnetic buckle 30 is first switched from the locking state to the unlocking state, that is, the unlocking operation piece 33 is pressed downwards, the spreading leg 332 below the unlocking operation piece 33 is contacted with the groove 3112 of the elastic arm 311 and pushes the groove 3112, so that the elastic arm 311 is spread outwards by the matching of the pushing inclined plane 331 on the spreading leg 332 and the pushed inclined plane 3111 on the groove 3112, the lock head 312 connected with the elastic arm 311 is driven to be spread outwards together, the locking with the locking structure 322 on the inserting and matching lock part 32a is separated, and the male buckle 31 and the female buckle 32 are in the unlocking state; meanwhile, the female buckle 32 and the male buckle 31 are forcibly pulled apart in opposite insertion directions, so that the pulling force is greater than the mutual magnetic attraction force between the first magnetic attraction structure 34 and the second magnetic attraction structure 35, and the male buckle 31 and the female buckle 32 are separated from each other.

When the male buckle 31 is to be engaged with the female buckle 32, the mating lock portion 32a is first aligned with the mating hole 362 in the outer cover 36; then, the male buckle 31 and the female buckle 32 are mutually close, and under the mutual magnetic attraction action of the first magnetic attraction structure 34 and the second magnetic attraction structure 35, the pushing structure 321 on the mating lock portion 32a easily passes over the lock head 312, so that the locking structure 322 and the lock head 312 are mutually locked, and the male buckle 31 and the female buckle 32 are locked, as shown in fig. 9.

Referring to fig. 12 to 15, a magnetic buckle 30a according to a second embodiment of the present invention is substantially the same as the first embodiment, except that:

first, the outer cover 36 of the present embodiment is convexly provided with ribs 364, the ribs 364 are located on the side walls of the outer cover 36, preferably, the ribs 364 are located on the two opposite side walls of the outer cover 36, and the ribs 364 increase the friction resistance, so as to facilitate the operation of the magnetic fastener 30a by the operator; in the first embodiment, the outer cover 36 is not provided with the ribs 364.

Secondly, the pushing inclined surface 331 of the spreading leg 332 in this embodiment is in pushing fit with one end of the elastic arm 311 away from the lock head 312, and the pushing inclined surface 331 of the spreading leg 332 directly applies force to one end of the elastic arm 311 away from the lock head 312, that is, the spreading leg 332 is located between the elastic arm 311 and the intermediate support arm 314 (see fig. 15), so the elastic arm 311 in this embodiment is not provided with the pushed inclined surface 3111 and the groove 3112 which are in fit with the pushing inclined surface 331. Because the spreader legs 332 of this embodiment are arranged in pairs and spaced apart, the intermediate support arms 314 are captured in the gaps between the pairs of spreader legs 332.

Thirdly, since the pushing inclined plane 331 of the spreading leg 332 of the present embodiment directly applies force to the end of the elastic arm 311 away from the lock head 312, in order to make the unlocking operation member 33 more reliably reset, the magnetic buckle 30a of the present embodiment further includes an elastic member 37 for providing elastic force for resetting the unlocking operation member 33, and the elastic member 37 is preferably a spring, and of course, is designed to be an elastic plastic or other structure according to actual needs; and the elastic member 37 abuts between the unlocking operation member 33 and the male buckle 31 (see fig. 14), but not limited thereto; in the first embodiment, since the pushing slope 331 of the spreading leg 332 applies force to the end of the elastic arm 311 connected to the lock head 312, the reset of the lock releasing operation member 33 is realized by the elastic arm 311.

Fourth, in the present embodiment, the thickness of the first magnetic attraction structure 34 is 5.0 mm, and in the first embodiment, the thickness of the first magnetic attraction structure 34 is 3.8 mm.

Except for the above differences, the other parts are the same as those of the first embodiment, and thus are not described herein again.

The operation principle of the magnetic buckle 30a according to the second embodiment will be described with reference to fig. 12 to 15.

When the male buckle 31 is to be separated from the female buckle 32, the lock release operation piece 33 is pressed downwards to enable the elastic piece 37 to be in a pressed state, the pushing inclined plane 331 of the expanding leg 332 below the lock release operation piece 33 directly applies force to one end of the elastic arm 311 far away from the lock head 312, so that the elastic arm 311 is expanded outwards to drive the lock head 312 connected with the elastic arm 311 to expand outwards together, and the lock with the lock matching structure 322 on the plug-in lock matching part 32a is separated, so that the male buckle 31 and the female buckle 32 are in a lock release state; meanwhile, the female buckle 32 and the male buckle 31 are pulled apart by force in opposite directions of opposite insertion, so that the pulling force is greater than the mutual magnetic attraction force between the first magnetic attraction structure 34 and the second magnetic attraction structure 35, and the male buckle 31 and the female buckle 32 are separated from each other, at this time, the reset of the lock release operation piece 33 is realized by the elastic piece 37.

When the male buckle 31 is to be engaged with the female buckle 32, the mating lock portion 32a is first aligned with the mating hole 362 in the outer cover 36; then, the male buckle 31 and the female buckle 32 are mutually close, and under the mutual magnetic attraction action of the first magnetic attraction structure 34 and the second magnetic attraction structure 35, the pushing structure 321 on the mating lock portion 32a easily passes over the lock head 312, so that the mating lock structure 322 and the lock head 312 are mutually locked, and the male buckle 31 and the female buckle 32 are locked, as shown in fig. 14.

Referring to the third embodiment shown in fig. 16 to 18, the magnetic buckle 30b of the present embodiment has substantially the same structure as the magnetic buckle 30a of the second embodiment, and the differences are as follows:

first, in the present embodiment, the lock releasing operation member 33 is a square button; in the second embodiment, the lock release operation member 33 is a circular button.

Secondly, in the present embodiment, the outer cover 36 is not provided with the ribs 364 in a protruding manner; in the second embodiment, the outer cover 36 is provided with ribs 364.

Third, in the present embodiment, the elastic element 37 abuts against the unlocking operation element 33 and the male buckle 31, and is deviated from the first embedding cavity 313; in the second embodiment, the elastic element 37 abuts against the release operation element 33 and the male buckle, and faces the first embedding cavity 313.

Except for the above differences, the other parts are the same as those of the second embodiment, and the working principle of the magnetic fastener 30b is also the same as that of the second embodiment, so the description thereof is omitted.

In summary, in the infant embracing belt 1 of the present invention, the harness 10 and the vest 20 are detachably connected by the magnetic fasteners 30, 30a, 30b, the magnetic fasteners 30, 30a, 30b realize the locking of the male buckle 31 and the female buckle 32 by the locking of the locking portion 31a and the opposite insertion locking portion 32a, and then the male buckle 31 and the female buckle 32 are kept in the opposite insertion state by the mutual magnetic attraction of the first magnetic attraction structure 34 arranged on the male buckle 31 and the second magnetic attraction structure 35 arranged on the female buckle 32, or the locking portion 31a and the opposite insertion locking portion 32a are kept in the opposite insertion state under the mutual repulsion of the first magnetic attraction structure 34 and the second magnetic attraction structure 35, so that the fastening between the male buckle 31 and the female buckle 32 is more reliable by the magnetic fastener 30 of the present invention; meanwhile, by the mutual magnetic attraction of the first magnetic attraction structure 34 and the second magnetic attraction structure 35, even when the user or the infant accidentally touches the lock release operation member 33 to release the lock between the lock portion 31a and the opposite insertion lock portion 32a, the male buckle 31 and the female buckle 32 are still in the opposite insertion state and are not automatically separated from each other, so that the safety is better, the infant carrying belt 1 is safer and more reliable, and the possibility of loss caused by the fact that the male buckle 31 and the female buckle 32 fall down everywhere due to the release of the lock between the lock portion 31a and the opposite insertion lock portion 32a can be prevented. Or, by mutual repulsion between the first magnetic structure 34 and the second magnetic structure 35, after the lock is released between the male buckle 31 and the female buckle 32, the male buckle 31 and the female buckle 32 are automatically separated, and the buckle releasing operation of the male buckle 31 and the female buckle 32 is further performed, so that the operation of the baby carrier 1 is more convenient.
