[Figure 5] 3 is a perspective view of the present invention. [Figure 6] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0020] The following clearly and completely describes the technical solutions in the embodiments of the present invention, together with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present invention.

[0021] As shown in Figures 1 to 6, the magnetic attraction buckle member includes a female buckle 1 and a male buckle 2 that are mutually attractable and engageable. The male buckle 2 is used to attach to a backpack, a baby strap, or a child car seat. The female buckle 1 is vertically engaged and fixed to the male buckle 2 by magnetic attraction. The female buckle 1 includes a case 3, a top cover 4 that fits into the case 3, a magnetic attraction member 6 that is attached to the case 3, and a button component 5. The female buckle 1 further includes an attachment chamber 7 with one end located within the case 3 and the other end protruding from the bottom of the case 3. A movable locking component 8 is provided within the attachment chamber 7, and a portion of the locking component 8 is pulled out from the attachment chamber 7 to lock the male buckle 2. The locking component 8 is shaped like an eight and is interlocked with the button component 5. The button component 5 presses the locking component 8 from both sides so that it can be moved to release the locking relationship with the male buckle 2. The mounting chamber 7 encloses the outer contour of the locking component 8, and the locking component 8 always moves in close contact with the inner contour of the mounting chamber 7, so that it can only move horizontally along the set pressing trajectory. When it wants to swing vertically, it is restricted by the mounting chamber 7, which greatly increases the stability of the movement of the locking component 8 and makes it less likely to swing, ensuring excellent product quality.

[0022] The locking component 8 includes a first locking member 16 and a second locking member 17 located on both sides, and a central plate 18 located at the top, and at the center of the top of the first locking member 16 and the second locking member 17, elastic pieces 19 extending upward are provided, connected to both ends of the central plate 18, and while the central plate 18 remains stationary, the first locking member 16 and the second locking member 17 can move laterally via the elastic pieces 19 to release the lock with the male buckle 2. The width and thickness of the elastic pieces 19 are smaller than those of the first locking member 16 and the second locking member 17, and the first locking member 16 and the second locking member 17 can move laterally with only a slight external force applied.

[0023] The first locking member 16, the second locking member 17, the center plate 18 and the elastic piece 19 are integrally molded, thereby avoiding unnecessary attachment and increasing the connection strength.

[0024] A cavity 20 for movement is formed between the first locking member 16 and the second locking member 17, and when the button component 5 is pressed from both sides, the first locking member 16 and the second locking member 17 move within the cavity 20 and are pushed so as to gradually approach each other, and when the button component 5 is released, the first locking member 16 and the second locking member 17 are reset by the repulsive force of the elastic pieces 19 and are movably reattached to both ends of the inner wall of the mounting chamber 7.

[0025] The mounting chamber 7 has through holes 21 on both sides, and the first locking member 16 and the second locking member 17 have latches 22 that are pulled out from the through holes 21 on one side of each member. The latches 22 are engaged with the male buckle 2 to lock it, and by pressing the first locking member 16 and the second locking member 17 on both sides, the latches are moved inward and inserted into the mounting chamber 7 to unlock it.

[0026] In a normal state, the locking component 8 is in a locking state, with the first locking member 16 and the second locking member 17 respectively pressed against both ends of the inner wall of the mounting chamber 7, and the latch 22 pulled out from the through-hole. When it is necessary to engage the female buckle 1 with the male buckle, the female buckle 1 is placed above the male buckle 2, and the mounting chamber 7 is engaged with the male buckle 2. Guided by magnetic attraction, the male buckle 2 opens the latches 22 protruding from both sides of the mounting chamber 7, and the first locking member 16 and the second locking member 17 move synchronously with the latches 22. When the male buckle 2 and the female buckle 1 are engaged and then attracted to each other, the locking component 8 pulls the latch 22 out from the through-hole 21 by its own repulsive force, and engages with and locks the male buckle 2. The advantages of the locking component of this solution are as follows: The locking component moves by its own elasticity to release the lock, and when engaging the male buckle 2 and the female buckle 1, there is no need to press the button component 5 to push the latch 22 to engage inside the mounting chamber 7; the magnetic attraction force alone is sufficient to push the latch 22 to engage inside the mounting chamber 7, making it easy for the user to operate.

[0027] An inclined guide portion 23 is provided on the outside of the latch 22. The guide portion 23 is an inclined slope and can play an assisting role in the process of engaging the male buckle 2 with the female buckle 1. This allows the male buckle 2 to more easily open the latch 22 along the guide portion 23, thereby achieving attachment to the female buckle 1 and facilitating attachment for the user.

[0028] The button component 5 includes a first button 9, a second button 10 located on both sides of the case 3, and an elastic member 11 supported between the first button 9 and the second button 10. The elastic member 11, the first button 9, and the second button 10 are integrally molded, and the first button 9 and the second button 10 are reset by the repulsive force of the elastic member 11 after being pressed.

[0029] Button chambers 12 are formed on both sides of the case 3, and a first button 9 and a second button 10 are mounted in the button chambers 12, with their outer ends exposed to the button chambers 12 for a user to press. When moving, the first button 9 and the second button 10 can only move within the button chambers 12, and when pressed to a certain extent, they touch the ends of the button chambers 12, limiting the maximum pressing distance of the first button 9 and the second button 10 to prevent them from being damaged by being pressed too deeply.

[0030] A slider 13 that extends to the inside of the case 3 is provided inside the first button 9 and the second button 10, and a chute 14 that fits the slider 13 is provided inside the case 3. When the first button 9 and the second button 10 are pressed, the slider 13 slides into the chute 14, making the button operation smoother, increasing the feel of the button press, and providing a positioning effect. This also increases the stability of the button movement, making it less likely to slip or rattle.

[0031] Stoppers 15 are provided on both sides of the first button 9 and the second button 10 to be locked in the button chamber 12 in order to prevent the first button 9 and the second button 10 from falling off.

[0032] With conventional connecting buckles, there is a risk of the male and female buckles coming off due to accidentally touching one of the buttons during daily use. In this design, the above structure allows only one of the buttons (22) to move when pressed, preventing the male and female buckles (2, 1) from fully unlocking. The lock can only be released when the first button (9) and the second button (10) are pressed simultaneously, thereby preventing the buckles from accidentally coming off due to accidentally touching them during daily use, ensuring product stability and a good user experience. When attached to a baby strap, it can greatly ensure the safety of the baby.

[0033] The case 3 is provided with a mounting groove 24 located at the outer edge of the mounting chamber 7 , and the magnetic attraction member 6 includes an annular magnet mounted in the mounting groove 24 .

[0034] The lower end of the male buckle 2 is provided with an annular mounting groove 25, which corresponds to the mounting groove 24 in the case 3. An attraction member 26 is provided within the mounting groove 25. The attraction member 26 comprises an annular metal member and an annular magnet, and when the male buckle 2 and the female buckle 1 are engaged with each other, the magnetic attraction member 6 and the attraction member 26 are attracted to each other. The annular design allows for attraction at various angles and increases the attraction area of ​​the magnetic attraction member 6 and the attraction member 26, thereby strengthening the attraction force between the female buckle 1 and the male buckle 2, allowing even young users to achieve good engagement even when adults are not very skilled at operating the buckle.

[0035] The male buckle 2 is provided with a mounting hole 27 that matches the circular outer contour of the mounting chamber 7, and a protruding position limiting step 28 is provided on the inner wall of the mounting hole 27. The latch 22 and the position limiting step 28 abut against each other to achieve vertical locking and prevent the female buckle 1 from being removed upwards. The mounting chamber 7 is recessed into the mounting hole 27, thereby achieving horizontal position limiting and preventing the female buckle 1 from swinging left and right.

[0036] A bottom sheet 29 for sealing the mounting groove 25 is provided at the bottom of the male buckle 2, and after the suction member 26 is engaged in the mounting groove 25, the bottom sheet 29 is engaged and attached. The bottom sheet 29 seals the bottom of the mounting hole 27, so that when the male buckle 2 is sewn to a strap or a backpack, protrusions on the fabric are prevented from being embedded in the mounting hole 27, which would affect the engagement of the mounting chamber 7.

[0037] The bottom of the case 3 is provided with a male buckle mounting groove 30 that fits the outer contour of the male buckle 2, and when the male buckle 2 and the female buckle 1 are engaged, the male buckle 2 is mounted in the male buckle mounting groove 30. The mounting of the male buckle 2 and the female buckle 1 is stable, the fitting between the mounting chamber 7 and the mounting hole 27 is a first lateral position restriction, the fitting between the outer contour of the male buckle 2 and the male buckle mounting groove 30 is a second lateral position restriction, the outer wall of the male buckle 2 and the inner wall of the male buckle mounting groove 30 are inclined surfaces that are bonded to each other, and the contact area is larger, which greatly increases stability after the female buckle 1 and the male buckle 2 are engaged and makes them less likely to shake.

[0038] The male buckle 2 includes a circular male buckle, thereby solving the problem that it can only be engaged at a fixed angle or cannot be engaged at an oblique angle.

[0039] An attachment portion 31 for inserting a webbing is provided at one end of the case 3, and a cover plate 32 is provided at the attachment portion 31. The cover plate is rotatably connected to the case 3 so as to be pivotally mounted thereon. After the webbing is inserted, the cover plate 32 can be rotated to close the cover plate in order to clamp the webbing and prevent it from loosening.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in all respects, the embodiments are illustrative and not limiting, and the scope of the present invention should be limited not by the above description but by the appended claims.
