In this embodiment, the inclined surfaces 51 on both sides extend obliquely from top to bottom to the outside of the channel.
The two sides of the second seat body 21 are also respectively provided with a sliding groove 211, and the positioning column 32 on each side is slidably arranged in the sliding groove 211 along the length extending direction of the sliding groove 211 on the corresponding side.
When the unlocking button 5 is operated to slide relative to the second seat 21 in the locked state, the positioning column 32 is driven to move towards the outer side of the channel due to the abutting action of the inclined surface 51, and the locking piece 3 is driven to synchronously rotate towards the outer side of the channel, so that the locking part 31 is disengaged from the hook part 121, and the locking mechanism is unlocked.
The magnetic hasp further comprises a driving piece 6, when the unlocking button 5 is operated to unlock the locking mechanism and then the unlocking button 5 is operated continuously, the driving piece 6 can drive the plug part 12 to move in the direction of being separated from the second base body 21, so that the hasp base component is disconnected with the hasp base component.
Specifically, the driving member 6 is rotatably disposed on the second seat 21, one end of the driving member 6 is disposed on the unlocking button 5, and the other end of the driving member 6 is capable of being in abutting engagement with the plug portions 12 of the first latch seat assembly 1a and the second latch seat assembly 1 b.
In this embodiment, the driving member 6 adopts a torsion spring, the middle part of the torsion spring is rotationally disposed on the second seat 21, one end of the torsion spring 6 is inserted on the unlocking button 5, the other end of the torsion spring is located below the plug portion 12, and the other end of the torsion spring moves upwards to be capable of being abutted against the plug portion 12 for matching.
Because the driving piece 6 adopts the torsional spring, when the unlocking button 5 is released after the plug part 12 of the first lock catch seat assembly 1a and the second lock catch seat assembly 1b are driven to be separated from the second seat body 21, the torsional spring can be automatically reset in the resetting process of the unlocking button 5, and the driving piece 6 is reset without independently setting a reset piece, so that the magnetic hasp is simpler in structure.
The magnetic buckle further includes a first elastic member 71 for urging the lock mechanism to return from the unlock state to the lock state, one end portion of the first elastic member 71 is provided on the lock member 3, and the other end portion of the first elastic member 71 is provided on the second seat 21.
The magnetic buckle further comprises a second elastic piece 72 for driving the unlocking button 5 to reversely slide and reset, one end part of the second elastic piece 72 is arranged on the unlocking button 5, and the other end part of the second elastic piece 72 is arranged on the second seat body 21.
The magnetic hasp further comprises a first magnetic component, the first magnetic component is respectively arranged between the first hasp seat component 1a and the hasp seat component and between the second hasp seat component 1b and the hasp seat component, the first hasp seat component 1a and the second hasp seat component 1b are enabled to move towards the direction that the plug part 12 is inserted into the channel of the second seat body 21 under the action of magnetic attraction of the first magnetic component, and therefore the plug part 12 of the first hasp seat component 1a and the plug part 12 of the second hasp seat component 1b can be matched and locked with the locking piece 3 on the corresponding side, and the hasp seat component are in a connection state.
The first magnetic assembly comprises a first magnet 81 and a second magnet 82, and the first magnet 81 and the second magnet 82 are opposite in magnetism and correspond to each other in position. Between the first latch base assembly 1a and the latch base assembly, a first magnet 81 and a second magnet 82 are provided on different parts of the two, respectively. Between the second latch base assembly 1b and the latch base assembly, the first magnet 81 and the second magnet 82 are also provided on different parts of the two, respectively.
In this embodiment, a first accommodating cavity 111 is disposed on an end portion of the first base 11 of the first latch base assembly 1a and the second latch base assembly 1b facing the latch base assembly, and a first magnet 81 is fixedly disposed in the first accommodating cavity 111. The left and right sides of the second seat body 21 are provided with a second accommodating cavity 212 towards one end of the latch seat assembly, and the second accommodating cavity 212 is internally used for fixedly arranging the second magnet 82.
A first end cap 112 is fixedly disposed outside the first accommodation chamber 111, so that the first magnet 81 is accommodated in the first housing 11. A second end cap 213 is fixedly provided on the outer side of the second accommodation chamber 212, so that the second magnet 82 is accommodated in the second housing 21. The arrangement of the first end cover 112 and the second end cover 213 does not affect the magnetic attraction between the first magnet 81 and the second magnet 82, so that the magnetic buckle has a neat and attractive appearance while fixing the first magnet 81 and the second magnet 82 through the arrangement of the first end cover 111 and the second end cover 213.
The magnetic attraction of the first magnetic assembly moves the first latch base assembly 1a and the second latch base assembly 1b in a first direction relative to the latch base assembly. The locking mechanism prevents the first latch base assembly 1a and the second latch base assembly 1b from moving relative to the latch base assemblies in a direction opposite to the first direction. The rotation axis 4 extends in a second direction, which is perpendicular to the first direction. In this embodiment, the first direction is downward, the second direction is front-to-back, and the locking mechanism prevents the first latch base assembly 1a and the second latch base assembly 1b from moving upward relative to the latch base assemblies.
The magnetic buckle can be applied to a child safety seat. The child safety seat comprises a seat body and a safety belt assembly arranged on the seat body, and the magnetic buckle is arranged on the safety belt assembly. When the child safety seat is installed on an automobile seat for use, the latch seat assembly and the latch seat assembly are connected so as to restrain a child in the seat body through the seat belt assembly. When an automobile collides, the impact force generated by the collision moves the first latch base assembly 1a and the second latch base assembly 1b relative to the latch base assembly in a direction opposite to the first direction. Namely, the latch seat component and the latch seat component can be effectively prevented from being disconnected through the combined action of the magnetic attraction of the first magnetic component and the locking mechanism.
The first latch seat component 1a is provided with a concave part 13, the second latch seat component 1b is provided with a convex part 14 matched with the concave part 13, and when the latch seat component is connected with the latch seat component, the convex part 14 is clamped in the concave part 13, so that the first latch seat component 1a and the second latch seat component 1b form an integral body to be connected with the latch seat component in an inserting way.
The magnetic hasp further comprises a second magnetic component, the second magnetic component is arranged between the first hasp seat component 1a and the second hasp seat component 1b, and the first hasp seat component 1a and the second hasp seat component 1b are fixedly connected together under the action of magnetic attraction of the second magnetic component and then are connected with the hasp seat component in an inserting mode.
In this embodiment, the second magnetic assembly includes a third magnet 91 and a fourth magnet 92, the positions of the third magnet 91 and the fourth magnet 92 correspond to each other, the magnetism is opposite, the third magnet 91 is disposed on the first latch base assembly 1a at a position corresponding to the recess 13, and the fourth magnet 92 is disposed on the protrusion 14 of the second latch base assembly 1 b.
The direction of the magnetic attraction force of the second magnetic component can be the same as the direction of the magnetic attraction force of the first magnetic component, namely, the magnetic attraction force of the second magnetic component is along the up-down direction. The direction of the magnetic attraction force of the second magnetic component can also be perpendicular to the direction of the magnetic attraction force of the first magnetic component, namely, the magnetic attraction force of the second magnetic component extends along the front-back direction. The magnetic attraction force of the second magnetic assembly preferably extends in the front-rear direction so that the cross-section of the third magnet 91 and the fourth magnet 92 can be arranged relatively large due to the size allowed, so that the requirements for the positions of the third magnet 91 and the fourth magnet 92 are relatively low when they are mounted, and they can be offset from each other by a small distance.
In this embodiment, a third accommodating cavity is disposed at a position corresponding to the recess 13 on the first latch base assembly 1a, and the third accommodating cavity is used for fixedly disposing the third magnet 91. The convex portion 14 of the second latch base assembly 1b is provided with a fourth accommodating cavity 141, and the fourth accommodating cavity 141 is used for fixedly arranging the fourth magnet 92.
A third end cap 131 is fixedly provided at the outer side of the third accommodating chamber so as to accommodate the third magnet 91 in the third accommodating chamber. A fourth end cap 142 is fixedly provided at the outer side of the fourth receiving chamber 141 so as to receive the fourth magnet 92 in the fourth receiving chamber 142. The arrangement of the third end cover 131 and the fourth end cover 142 does not affect the magnetic attraction between the third magnet 91 and the fourth magnet 2, so that the magnetic buckle has a neat and attractive appearance while fixing the third magnet 91 and the fourth magnet 92 through the arrangement of the third end cover 131 and the fourth end cover 142.
When the latch base assembly is connected with the latch base assembly, the magnetic latch buckle makes the first latch base assembly 1a close to the second latch base assembly 1b, and makes the convex part 14 on the second latch base assembly 1b clip into the concave part 13 on the first latch base assembly 1a under the action of the magnetic attraction of the second magnetic assembly, so as to fixedly connect the first latch base assembly 1a and the second latch base assembly 1b together, as shown in fig. 3.
The latch base assembly is integrally close to the latch base assembly, and the plug parts 12 of the first latch base assembly 1a and the second latch base assembly 1b are moved towards the direction of inserting into the channel of the second base body 21 under the action of magnetic attraction of the first magnetic assembly. At this time, the locking member 3 locates the locking portion 31 in the passage of the second housing 21 by the elastic force of the first elastic member 6. The plug part 12 moves downwards in the channel of the second seat body 21 until the outer side surface 121b of the hook part 121 abuts against the second matching surface 312 to be matched, and when the plug part 12 continues to move downwards, the locking piece 3 is driven to rotate towards the outer side direction of the channel around the rotating shaft 4 relative to the second seat body 21 through the inclined surface matching of the outer side surface 121b and the second matching surface 312.
