[0043] Embodiment 1

[0044] like Figure 1 , Figure 2 Figure 5 and Figure 6 As shown, a magnetic buckle includes a first buckle 10 and a second buckle 20, the first buckle 10 includes a male buckle 11, a rotating part 12, a first magnetic part 13 and a second magnetic part 14, the rotating part 12 is rotatably arranged on the male buckle 11, and the first magnetic part 13 and the second magnetic part 14 are both arranged on the rotating part 12; the second buckle 20 includes a female buckle 21 and a third magnetic part 22, the female buckle 21 is provided with a receiving groove 211, and the third magnetic part 22 is arranged in the receiving groove 211.

[0045] In the engaged state, the rotating member 12 is located in the receiving groove 211 , and the first magnetic member 13 is attracted to the third magnetic member 22 . The rotating member 12 is rotated to repel the second magnetic member 14 and the third magnetic member 22 , thereby popping the male buckle 11 and the female buckle 21 apart.

[0046] Specifically, the magnetic buckle includes two parts, namely, a first buckle 10 and a second buckle 20. The first buckle 10 is used to connect with the first strip, and the second buckle 20 is used to connect with the second strip. The connection between the first strip and the second strip is achieved by the fixed connection between the first buckle 10 and the second buckle 20. The first strip and the second strip can be connected to wearable devices such as smart watches and smart bracelets to fix the wearable devices on the wrists, legs, necks, waists or other body parts of the wearer.

[0047] like Figure 5As shown, the first buckle 10 includes a male buckle 11, a rotating member 12, a first magnetic member 13 and a second magnetic member 14. The male buckle 11 and the rotating member 12 can be made of conventional materials such as plastic, plastic, composite material, rubber, etc. The first magnetic member 13 and the second magnetic member 14 are magnets. The rotating member 12 is rotatably arranged on the male buckle 11, and the first magnetic member 13 and the second magnetic member 14 are both arranged on the rotating member 12. When the rotating member 12 rotates, the first magnetic member 13 and the second magnetic member 14 can rotate together with the rotating member 12.

[0048] like Figure 6 As shown, the second buckle 20 includes a female buckle 21 and a third magnetic member 22. The female buckle 21 can be made of conventional materials such as plastic, plastic, composite material, rubber, etc., and the third magnetic member 22 is a magnet. The female buckle 21 is provided with a receiving groove 211, and the third magnetic member 22 is arranged in the receiving groove 211. When the rotating member 12 is located in the receiving groove 211, a magnetic attraction force can be generated between the first magnetic member 13 and the third magnetic member 22, and a repulsive magnetic force can be generated between the second magnetic member 14 and the third magnetic member 22.

[0049] The male buckle 11 and the female buckle 21 can be roughly rectangular in shape or circular in shape. Of course, the male buckle 11 and the female buckle 21 can also be curved, or have other irregular shapes depending on the wearing position of the wearable device.

[0050] When you need to close the magnetic buckle, Figure 1 As shown, the first magnetic member 13 on the rotating member 12 is rotated to the receiving groove 211 on the corresponding female buckle 21, and the first magnetic member 13 and the third magnetic member 22 in the receiving groove 211 generate an attractive magnetic force to suck the rotating member 12 into the receiving groove 211, and the first magnetic member 13 and the third magnetic member 22 are attracted together to achieve the buckling of the first buckle 10 and the second buckle 20; when the magnetic buckle needs to be opened, the rotating member 12 is rotated to make the second magnetic member 14 and the third magnetic member 22 face each other, and the second magnetic member 14 and the third magnetic member 22 repel each other, so that the male buckle 11 and the female buckle 21 are bounced apart, and the first buckle 10 and the second buckle 20 are opened.

[0051] In this embodiment, the automatic fastening of the first buckle 10 and the second buckle 20 is achieved through the magnetic attraction of the two magnetic parts. When the two buckles need to be opened, it is only necessary to rotate the rotating part 12 to make the second magnetic part 14 and the third magnetic part 22 face each other, and pop open the two buckles to achieve the opening of the magnetic buckles. The whole wearing process is convenient and quick, and the user can realize one-handed operation.

[0052] In one example, the first magnetic member 13 and the second magnetic member 14 are arranged on the rotating member 12 at intervals along the rotation direction of the rotating member 12, and the third magnetic member 22 is arranged at the bottom of the receiving groove 211. Specifically, the rotating member 12 is cylindrical, the first magnetic member 13 and the second magnetic member 14 are arranged on the rotating member 12 at intervals along the radial direction of the rotating member 12, the receiving groove 211 is arranged at the end of the female buckle 21, the receiving groove 211 is adapted to the shape of the rotating member 12, and the third magnetic member 22 is arranged at the bottom of the receiving groove 211, that is, the third magnetic member 22 is arranged opposite to the opening of the receiving groove 211.

[0053] like Figure 2 As shown, the first buckle 10 and the second buckle 20 are connected by left and right splicing. When the magnetic buckle needs to be fastened, the first magnetic part 13 on the rotating part 12 is facing the opening of the receiving groove 211, and the first magnetic part 13 and the third magnetic part 22 at the bottom of the receiving groove 211 are attracted to each other, and the rotating part 12 is attracted to the receiving groove 211, and the first magnetic part 13 and the third magnetic part 22 are attracted together; when the magnetic buckle needs to be opened, the rotating part 12 is rotated in the receiving groove 211 to separate the first magnetic part 13 from the third magnetic part 22, and rotated to the second magnetic part 14 and the third magnetic part 22. The second magnetic part 14 and the third magnetic part 22 repel each other, and the male buckle 11 and the female buckle 21 are ejected. In order to facilitate the rotation of the rotating part 12, a hand-held part can also be provided outside the rotating part 12, and the user can realize the rotation of the rotating part 12 by rotating the hand-held part.

[0054] The first magnetic member 13, the second magnetic member 14 and the third magnetic member 22 are all multiple and the number is the same. The multiple first magnetic members 13 are arranged on the rotating member 12 at intervals along the axial direction of the rotating member 12, the multiple second magnetic members 14 are arranged on the rotating member 12 at intervals along the axial direction of the rotating member 12, and the multiple third magnetic members 22 are arranged at intervals at the bottom of the accommodating groove 211. The multiple first magnetic members 13 and the multiple second magnetic members 14 are arranged one-to-one with the multiple third magnetic members 22.

[0055] When the rotating member 12 is disposed in the receiving groove 211, the plurality of first magnetic members 13 and the plurality of third magnetic members 22 are disposed one by one and attracted together to increase the magnetic attraction between the first buckle 10 and the second buckle 20, and prevent the first buckle 10 and the second buckle 20 from being opened due to force. The rotating member 12 is rotated to repel the plurality of second magnetic members 14 and the plurality of third magnetic members 22, so as to increase the repulsive force between the first buckle 10 and the second buckle 20, and the first buckle 10 and the second buckle 20 are ejected.

[0056] like Figure 7As shown, the male buckle 11 is provided with a receiving portion 111, and the rotating member 12 is rotatably arranged in the receiving portion 111. The rotating member 12 is arranged in the receiving portion 111 of the male buckle 11, so that the rotating member 12 and the male buckle 11 form a whole, so as to avoid the rotating member 12 protruding from the male buckle 11 and affecting the daily use of the user.

[0057] Embodiment 2

[0058] Based on the above embodiment 1, Figure 1 and Figure 2 As shown, the first buckle 10 in the above embodiment also includes a buckle 15, which is connected to the rotating member 12; a slot 212 is provided on the female buckle 21; in the engaged state, the buckle 15 is engaged in the slot 212, and when the rotating member 12 is rotated, the engagement between the buckle 15 and the slot 212 is released.

[0059] Specifically, the buckle 15 is fixedly connected to the rotating member 12. When the rotating member 12 rotates, the buckle 15 is driven to rotate. When the buckle 15 rotates, the rotating member 12 is also driven to rotate. A slot 212 is provided on the end of the female buckle 21 away from the receiving groove 211. When the rotating member 12 is set in the receiving groove 211, the buckle 15 is set in the slot 212, and the first magnetic member 13 and the third magnetic member 22 are attracted together; the buckle 15 is rotated to make the buckle 15 leave the slot 212, and drive the second magnetic member 14 on the rotating member 12 to be opposite to the third magnetic member 22 in the receiving groove 211 and generate a repulsive force, so that the first buckle 10 and the second buckle 20 pop open.

[0060] The first buckle 10 and the second buckle 20 of this embodiment are attracted together by the first magnetic member 13 and the third magnetic member 22, and the buckle 15 cooperates with the slot 212 to achieve double fixation of the first buckle 10 and the second buckle 20, thereby preventing the first buckle 10 and the second buckle 20 from being separated due to a large force;

[0061] When the first buckle 10 and the second buckle 20 need to be separated, Figure 3 and Figure 4 As shown, it is only necessary to rotate the buckle 15 to disengage the buckle 15 from the slot 212, separate the first magnetic component 13 from the third magnetic component 22, and make the second magnetic component 14 face the third magnetic component 22. Through the repulsive force between the second magnetic component 14 and the third magnetic component 22, the first buckle 10 and the second buckle 20 are automatically popped open to facilitate the separation of the magnetic buckles, making the wearing method more convenient and quick.

[0062] In one example, the buckle 15 includes a first connecting portion 151, a locking portion 152 and a second connecting portion 153. The first connecting portion 151 and the second connecting portion 153 are respectively arranged at two ends of the locking portion 152. One end of the first connecting portion 151 away from the locking portion 152 is connected to one end of the rotating member 12, and one end of the second connecting portion 153 away from the locking portion 152 is connected to the other end of the rotating member 12. In the locked state, the locking portion 152 is locked in the locking slot 212.

[0063] Specifically, Figure 1 As shown, one end of the first connecting portion 151 is connected to one end of the rotating member 12, the other end of the first connecting portion 151 is connected to one end of the locking portion 152, the other end of the locking portion 152 is connected to one end of the second connecting portion 153, and the other end of the second connecting portion 153 is connected to the other end of the rotating member 12. The first connecting portion 151, the locking portion 152, the second connecting portion 153 and the rotating member 12 are connected end to end in sequence to form a closed rectangular ring structure.

[0064] The receiving groove 211 is provided at the end of the female buckle 21, and notches 2111 are respectively provided on the two oppositely disposed side walls of the receiving groove 211, and the first connecting portion 151 and the second connecting portion 153 respectively extend out of the notches 2111. The clamping groove 212 is provided at one end of the female buckle 21 away from the receiving groove 211, and the clamping groove 212 is provided on the surface of the female buckle 21, and the clamping groove 212 passes through both sides of the female buckle 21 along the width direction of the female buckle 21.

[0065] When you need to close the magnetic buckle, Figure 1 As shown, the buckle 15 is rotated downward so that the first magnetic member 13 on the rotating member 12 corresponds to the third magnetic member 22 in the receiving groove 211 as much as possible, and the first magnetic member 13 and the third magnetic member 22 attract each other, and the rotating member 12 is sucked into the receiving groove 211. At this time, the buckle 15 is located above the female buckle 21 and corresponds to the slot 212. The buckle 15 is further rotated downward so that the buckle 15 enters the slot 212. At this time, the first magnetic member 13 on the rotating member 12 is rotated to be just opposite to the third magnetic member 22 in the receiving groove 211, and the buckling of the first buckle 10 and the second buckle 20 is completed. Figure 2 As shown, when the first buckle 10 and the second buckle 20 are buckled together, the rotating member 12 is arranged in the receiving groove 211, and the buckle 15 is arranged in the buckle groove 212. The first buckle 10 and the second buckle 20 can form a whole, and the aesthetics of the magnetic buckle can be improved.

[0066] When the first buckle 10 and the second buckle 20 need to be opened, Figure 3 As shown, the buckle 15 is rotated upward to disengage the buckle 15 from the slot 212. When the buckle 15 rotates, the rotating member 12 is driven to rotate. When the second magnetic member 14 on the rotating member 12 corresponds to the third magnetic member 22 in the receiving slot 211, as shown in FIG. Figure 4 As shown, the second magnetic member 14 and the third magnetic member 22 repel each other, and the first buckle 10 and the second buckle 20 are bounced apart, and the first buckle 10 and the second buckle 20 are separated, so that the magnetic buckle is opened.
