Description

Technical Field

[0001] This utility model relates to the field of smart wearable devices, and in particular to a magnetic watch strap. Background Technology

[0002] With the improvement of living standards and the advancement of technology, mechanical watches and smartwatches are becoming increasingly popular. Most watch straps typically use a buckle or pin connection, which is somewhat cumbersome to wear. To solve this problem, magnetic watch straps, designed using magnetic technology, have emerged. They use magnetic force to quickly fix and unfasten the strap, providing a more convenient user experience than traditional buckles or pins, greatly improving the wearing experience and gaining widespread popularity. However, existing magnetic watch straps still have some shortcomings in practical use. When quickly adjusting the strap length to fit different wrist sizes, the stability of the connection between the straps cannot be guaranteed, and the strap may loosen and fall off under significant external impact. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to design a magnetic watch strap that can adapt to wrists of different sizes while improving the stability of the magnetic watch strap connection.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A magnetic watch strap is designed, including a first watch strap and a second watch strap. The end of the first watch strap opposite to the second watch strap includes a first fastening section, and the end of the second watch strap opposite to the first watch strap includes a second fastening section that can be connected to the first fastening section. The first fastening section includes a plurality of first magnetic clasps, and the second fastening section includes at least one second magnetic clasp and a plurality of second magnetic snaps. The first magnetic clasp and the second magnetic clasp can be magnetically attracted and snapped together.

[0006] In this design, the first fastening section of the first watch strap is connected to the second fastening section of the second watch strap. The first fastening section includes several first magnetic clasps, each of which can be fixedly connected to a second magnetic clasp using both magnetic attraction and snap-fit ​​methods. This addition of snap-fit ​​connection to the magnetic attraction ensures connection stability, preventing the watch strap from loosening or falling off even under significant external impact. By using multiple first magnetic clasps and changing the engagement position of the second magnetic clasps, the length of the watch strap after fastening can be quickly adjusted, adapting to wrists of different sizes without the need to disassemble or replace the strap. Furthermore, the second watch strap also features several second magnetic clasps. After a second magnetic clasp engages with a first magnetic clasp, it can magnetically connect to a first magnetic clasp connected to the rear of that first magnetic clasp. This provides a double-connection safety mechanism and also secures the end of the first watch strap. Through the above design, the magnetic watch strap of this solution can adapt to wrists of different sizes, while also improving the stability of the magnetic watch strap connection, greatly enhancing the user experience.

[0007] Furthermore, the first magnetic snap fastener includes a first housing, and the second magnetic snap fastener includes a second housing. The second housing has a snap-fit ​​cavity, and the first housing can be snapped into the snap-fit ​​cavity.

[0008] The second housing is larger than the first housing. The two opposite sidewalls of the second housing protrude toward the first housing in the width direction, thereby forming a fastening cavity. After the first housing is fastened into the fastening cavity, its movement can be restricted, thus improving the stability of the connection.

[0009] Furthermore, the first housing is provided with a first magnetic attracting piece, and the second housing is provided with a second magnetic attracting piece that can attract the first magnetic attracting piece.

[0010] Both the first and second magnetic absorbing plates have magnetic blocks installed on their surfaces. Based on the concentricity principle of magnets and the attraction between the north and south poles of magnets, the two magnetic blocks attract each other and play a role in magnetic positioning, thus completing the first fixing of the first and second magnetic absorbing clips.

[0011] Furthermore, the second magnetic snap fastener also includes an elastic sheet disposed within the second housing and a movable button disposed at both ends of the elastic sheet and connected to the elastic sheet. The movable button has a snap fastener protruding from one side facing the second magnetic snap fastener. The second magnetic snap fastener has a slot corresponding to the snap fastener, and the first magnetic snap fastener has a card interface. When the first magnetic snap fastener and the second magnetic snap fastener are engaged, the snap fastener is engaged with the card interface.

[0012] The second magnetic clasp and the second housing form a button cavity. The snap-fit ​​cavity and the mounting cavity are located on opposite sides of the second magnetic clasp along its height. Two movable buttons are installed within the button cavity and are held against the side wall of the second housing by an elastic plate. Applying force to the two movable buttons compresses the elastic plate, causing them to move closer together. Removing the force causes the two movable buttons to move away under the elastic force of the elastic plate. The first housing has a hollow interior. The snap-fit ​​interface of the first magnetic clasp connects to the hollow cavity inside the first housing. When the first and second magnetic clasps are attracted to each other, the snap-fit ​​and the interface automatically align. The end of the snap-fit ​​extends from the interface into the hollow cavity inside the first housing, where the elastic force of the elastic plate causes the end of the snap-fit ​​to engage securely with the interface, achieving secondary fixation of the first and second magnetic snap-fits.

[0013] Furthermore, the active button is provided with a connecting post, and the active button is connected to the elastic sheet through the connecting post.

[0014] To reduce the difficulty of connecting the active button and the elastic plate during watch strap assembly, a connecting post is set on the active button, and the elastic plate can be made with through holes or hooks. The connection is made directly with the connecting post using through holes or hooks, which not only makes the connection reliable and less prone to failure, but also simplifies the operation and helps improve assembly efficiency.

[0015] Furthermore, the snap fastener has a first inclined surface, and the inner wall of the card interface includes a second inclined surface. When the snap fastener is engaged with the card interface, the first inclined surface slides along the second inclined surface.

[0016] When the first and second magnetic clips are magnetically attracted to each other, the first inclined surface of the snap fastener abuts against the second inclined surface of the card interface. Under the action of magnetic attraction, the first inclined surface slides along the second inclined surface. At the same time, the second inclined surface exerts a horizontal force on the first inclined surface along the width of the watch band, causing the two movable buttons to press against the elastic sheet and move closer to each other. After the magnetic attraction is completed, that is, the first inclined surface disengages from the second inclined surface, and the horizontal force disappears. Under the elastic force of the elastic sheet, the end of the snap fastener is locked and fixed to the card interface. Therefore, when the first and second magnetic snap fasteners are engaged, there is no need to manually press the movable buttons; the locking between the snap fastener and the card interface can be achieved by relying on magnetic attraction.

[0017] Furthermore, the second housing has a button hole on its opposite sidewall along the width direction, and the active button includes a button protrusion that passes through the button hole and protrudes from the sidewall of the second housing.

[0018] Separating the first and second watch bands requires manual operation. When separating the first and second watch bands, press the button protrusions from both sides of the second housing with your fingers to separate the clasp from the card interface, and then separate the first and second magnetic clasps.

[0019] Furthermore, the second magnetic clasp is provided with a third magnetic piece that can attract the first magnetic piece.

[0020] A third magnetic piece is installed on the surface of the second magnetic clasp that is in contact with the first magnetic clasp. Through the magnetic attraction between the third magnetic piece and the first magnetic piece, after the second magnetic clasp is fastened to a first magnetic clasp, the second magnetic clasp can be magnetically connected to the first magnetic clasp connected behind the first magnetic clasp. In addition to serving as a double connection security mechanism, it also serves to fix the end of the first watch strap.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] In this design, the first fastening section of the first watch strap is connected to the second fastening section of the second watch strap. The first fastening section includes several first magnetic clasps, each of which can be fixedly connected to a second magnetic clasp using both magnetic attraction and snap-fit ​​methods. This addition of snap-fit ​​connection to the magnetic attraction ensures connection stability, preventing the watch strap from loosening or falling off even under significant external impact. By using multiple first magnetic clasps and changing the engagement position of the second magnetic clasps, the length of the watch strap after fastening can be quickly adjusted, adapting to wrists of different sizes without the need to disassemble or replace the strap. Furthermore, the second watch strap also features several second magnetic clasps. After a second magnetic clasp engages with a first magnetic clasp, it can magnetically connect to a first magnetic clasp connected to the rear of that first magnetic clasp. This provides a double-connection safety mechanism and also secures the end of the first watch strap. Through the above design, the magnetic watch strap of this solution can adapt to wrists of different sizes, while also improving the stability of the magnetic watch strap connection, greatly enhancing the user experience.

Detailed Implementation

[0029] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0030] like Figures 1 to 5 As shown, this embodiment provides a magnetic watch strap, including a first watch strap 1 and a second watch strap 2. The end of the first watch strap 1 opposite to the second watch strap 2 includes a first fastening section 11, and the end of the second watch strap 2 opposite to the first watch strap 1 includes a second fastening section 21 that can be connected to the first fastening section 11. The first fastening section 11 includes a plurality of first magnetic clasps 12, and the second fastening section 21 includes at least one second magnetic clasp 22 and a plurality of second magnetic clasps 23. The first magnetic clasps 12 and the second magnetic clasps 22 can be magnetically and snapped together, and the first magnetic clasps 12 and the second magnetic clasps 23 can be magnetically connected. In this embodiment, the first watch strap 1 and the second watch strap 2 also include connecting sections. One end of the connecting section is connected to the watch case, and the other end is connected to the fastening section. Each connecting section is composed of multiple connecting modules assembled together. By adding or removing connecting modules, the length of the watch strap can be adjusted to accommodate wrists of different sizes.

[0031] like Figures 2 to 4As shown, the first magnetic snap fastener 12 includes a first housing 13, and the second magnetic snap fastener 22 includes a second housing 221. The second housing 221 has a snap-fit ​​cavity 222, into which the first housing 13 can be snapped. The second housing 221 is larger than the first housing 13. Two opposite sidewalls of the second housing 221 protrude towards the first housing 13 in the width direction, thereby forming the snap-fit ​​cavity 222. After the first housing 13 is snapped into the snap-fit ​​cavity 222, its movement is restricted, improving the stability of the connection. The first housing 13 is provided with a first magnetic piece 14, and the second housing 221 is provided with a second magnetic piece 223 that attracts the first magnetic piece 14. There are various ways to install and fix the first magnetic piece 14 and the second magnetic piece 223, such as by threaded connection or by adhesive. No specific limitation is made here. Both the first magnetic absorbing piece 14 and the second magnetic absorbing piece 223 have magnetic blocks installed on their surfaces. The magnetic blocks are made of neodymium magnets. Based on the concentricity principle of magnets and the attraction between the north and south poles of magnets, the two magnetic blocks attract each other and play a role in magnetic positioning, thus completing the first fixation of the first magnetic absorbing buckle 12 and the second magnetic absorbing buckle 22.

[0032] like Figures 3 to 5As shown, the second magnetic snap fastener 22 also includes an elastic sheet 224 disposed in the second housing 221 and a movable button 225 disposed at both ends of the elastic sheet 224 and connected to the elastic sheet 224. The movable button 225 has a snap fastener 2251 protruding on the side facing the second magnetic sheet 223. The second magnetic sheet 223 has a slot 2231 corresponding to the snap fastener 2251. The first magnetic sheet 14 has a card interface 141. When the first magnetic snap fastener 12 and the second magnetic snap fastener 22 are engaged, the snap fastener 2251 is engaged with the card interface 141. The second magnetic clasp 223 and the second housing 221 enclose a button cavity. The fastening cavity 222 and the mounting cavity are located on both sides of the second magnetic clasp 223 along the height direction. Two movable buttons 225 are installed in the button cavity and are pressed against the side wall of the second housing 221 by the elastic sheet 224. At the same time, a force is applied to the two movable buttons 225, which can compress the elastic sheet 224 and bring them closer to each other. After the force is removed, the two movable buttons 225 move away from each other under the elastic force of the elastic sheet 224. The first housing 13 has a hollow interior. The card interface 141 of the first magnetic absorbing piece 14 connects to the hollow cavity inside the first housing 13. When the first magnetic absorbing piece 14 and the second magnetic absorbing piece 223 are attracted to each other, the snap fastener 2251 and the card interface 141 automatically align. After the end of the snap fastener 2251 extends from the card interface 141 into the hollow cavity inside the first housing 13, it is locked and fixed to the card interface 141 by the elastic force of the elastic piece 224, thus achieving secondary fixation of the first magnetic absorbing snap fastener 12 and the second magnetic absorbing snap fastener 22. The snap fastener 2251 is provided with a first inclined surface 2253, and the inner wall of the card interface 141 includes a second inclined surface 1411. When the snap fastener 2251 is engaged with the card interface 141, the first inclined surface 2253 slides along the second inclined surface. When the first magnetic clasp and the second magnetic clasp are magnetically attracted to each other, the first inclined surface of the snap fastener abuts against the second inclined surface 1411 of the card interface. Under the action of magnetic attraction, the first inclined surface 2253 slides along the second inclined surface 1411. At the same time, the second inclined surface 1411 exerts a horizontal force on the first inclined surface 2253 along the width of the watch strap, causing the two movable buttons 225 to press against the elastic sheet 224 and move closer to each other. After the magnetic attraction is completed, that is, the first inclined surface 2253 disengages from the second inclined surface 1411, and the horizontal force disappears. Under the elastic force of the elastic sheet 224, the end of the snap fastener 2251 is locked and fixed to the card interface 141. Therefore, when the first magnetic snap fastener 12 and the second magnetic snap fastener 22 are engaged, there is no need to manually press the movable buttons. The locking between the snap fastener 2251 and the card interface 141 can be achieved by relying on magnetic attraction.In addition, to reduce the difficulty of connecting the active button 225 and the elastic piece 224 during the assembly of the watch strap, a connecting post 2252 is provided on the active button 225. The elastic piece 224 can be provided with through holes or hooks. The connecting post 2252 can be directly connected by the through holes or hooks. This not only ensures a reliable connection and prevents failure, but also simplifies the operation and improves assembly efficiency.

[0033] like Figure 4 and Figure 5 As shown, the second housing 221 has button holes 2211 on opposite sidewalls along its width direction. The movable button 225 includes a button protrusion 2254 that passes through the button hole 2211 and protrudes from the sidewall of the second housing 221. The separation of the first watch band 1 and the second watch band 2 requires manual operation. When separating the first watch band 1 and the second watch band 2, fingers simultaneously press the button protrusion 2254 from both sides of the second housing 221 to separate the clasp 2251 from the card interface 141, and then the first magnetic clasp 12 and the second magnetic clasp 22 can be separated.

[0034] like Figure 3 As shown, a third magnetic piece 231 is installed on the surface of the second magnetic clasp 23 that is in contact with the first magnetic clasp 12. A magnetic block is installed on the surface of the third magnetic piece 231. The magnetic block is a neodymium magnet. The first magnetic piece 14 and the third magnetic piece 231 form a magnetic attraction structure. Through the magnetic attraction between the third magnetic piece 231 and the first magnetic piece 14, after the second magnetic clasp 22 is fastened to a first magnetic clasp 12, the second magnetic clasp 23 can be magnetically connected to the first magnetic clasp 12 connected behind the first magnetic clasp 12. In addition to serving as a double connection security mechanism, it also serves to fix the end of the first watch strap 1.

[0035] In this embodiment, the first fastening section 11 of the first watch strap 1 is connected to the second fastening section 21 of the second watch strap 2. The first fastening section 11 includes a plurality of first magnetic clasps 12, each of which can be connected to a second magnetic clasp 22 via a magnetic clasp structure. This addition of a clasp connection to the magnetic connection ensures the stability of the connection, preventing the watch strap from loosening or falling off even when subjected to significant external impact. By setting multiple first magnetic clasps 12 and changing the fastening position of the second magnetic clasp 22, the length of the watch strap after fastening can be quickly adjusted, adapting to wrists of different sizes without the need to disassemble or replace the strap. Furthermore, the second watch strap also includes a plurality of second magnetic clasps 23. After a second magnetic clasp 22 is fastened to a first magnetic clasp 12, the second magnetic clasp 23 can be magnetically connected to a first magnetic clasp 12 connected to the rear of that first magnetic clasp 12. This serves as a double-connection safety mechanism and also secures the end of the first watch strap 1. Through the above design, the magnetic watch strap of this embodiment can adapt to wrists of different sizes, while also improving the stability of the magnetic watch strap connection, greatly enhancing the user experience.
