Description

A toggle connector Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a toggle-type connector. Background Technology

[0002] Wearable products, such as watches, fashion wristbands, and belts, use mechanical connectors for connection. Taking watch straps as an example, existing strap connectors typically have a male buckle on the first clasp and movable female buckles on both sides of the second clasp, with the male buckle locking into each of the two female buckles. The first and second clasps can be separated by pressing the two female buckles inwards along the width of the strap. The advantage of this structure is that users can easily operate it with one hand; the disadvantage is that, because the female buckles are located in the first direction of the strap, accidental collision with one of the female buckles may cause the female buckle on that side to disengage from the male buckle, resulting in one side of the strap falling off or even the entire strap falling off. Therefore, it is necessary to design a toggle-type connector that prevents accidental disengagement. Technical issues

[0003] Design a toggle-type connector that can prevent accidental dislodgement. Technical solutions

[0004] This application relates to a toggle-type connector, comprising:

[0005] First fastener;

[0006] The second fastener is detachably connected to the first fastener;

[0007] Two toggle members are slidably disposed on both sides of the second fastener in the first direction and move between the locked position and the unlocked position in the second direction. Beneficial effects

[0008] This toggle connector connects the first and second fasteners by locking the first fastener with two toggle pieces. To release the connection between the first and second fasteners, both toggle pieces need to slide along the second direction to unlock, effectively preventing the first and second fasteners from being accidentally disconnected due to external pressure or collision of the toggle pieces.

[0024] Please refer to Figure 1. A toggle-type connector includes:

[0025] First fastener 1;

[0026] The second fastener 2 is detachably connected to the first fastener 1;

[0027] Two toggle members 3 are slidably disposed on both sides of the second fastener 2 in the first direction, and move between the locked position and the unlocked position in the second direction.

[0028] This toggle connector connects the first fastener 1 and the second fastener 2 by locking the first fastener with the two toggle pieces 3. When the connection between the first fastener 1 and the second fastener 2 is released, both toggle pieces 3 need to slide along the second direction to unlock, which effectively avoids the phenomenon of the first fastener 1 and the second fastener 2 being accidentally disconnected due to the toggle pieces 3 being squeezed or collided by external forces.

[0029] Referring to Figures 1 to 7, in one embodiment, the first fastener 1 is provided with two mating portions 11, and the two actuating members 3 are respectively engaged with the two mating portions 11. The two actuating members 3 are slidable relative to the second fastener 2 along a second direction to move closer to or away from the mating portions 11. The second direction is set at an angle of 45°-90° to the first direction. It also includes an elastic member 4, which is installed on the second fastener 2. The elastic member 4 is used to drive the actuating members 3 to move towards the mating portions 11 so that the first fastener 1 and the second fastener 2 remain locked.

[0030] The first fastener 1 and the second fastener 2 are connected by two actuating parts 3 engaging with two mating parts 11. When the connection between the first fastener 1 and the second fastener 2 is released, both actuating parts 3 need to slide along the second direction to move away from the two mating parts 11 to reach the unlocked position.

[0031] Referring to Figures 6 and 11, in one embodiment, at least one of the second fastener 2 and the actuating member 3 is provided with a limiting portion 323, and the end of the elastic member 4 is limited by the limiting portion 323.

[0032] The limiting part 323 can restrict the position of the elastic member 4 and prevent the elastic member 4 from disengaging from the second fastener 2 and / or the actuating member 3.

[0033] Referring to Figure 2, in one embodiment, the second direction is perpendicular to the first direction.

[0034] The second direction is perpendicular to the first direction, which allows the user to slide the two toggle pieces 3 simultaneously, facilitating one-handed operation and conforming to ergonomics.

[0035] Referring to Figure 6, in one embodiment, the second fastener 2 is provided with mounting holes 21 on both sides in the first direction, and the actuating member 3 is disposed in the mounting holes 21.

[0036] Placing the actuating element 3 in the mounting hole 21 can effectively limit the position of the actuating element 3 and reduce the risk of damage to the actuating element 3 caused by external forces.

[0037] Please refer to Figures 1, 5 and 6. In one embodiment, the second fastener 2 and the actuating member 3 are respectively provided with a pin 22 and an elongated hole 321 that slides with the pin 22.

[0038] The guide structure that engages with the pin 22 and the elongated hole 321 has fewer parts and is easier to assemble. The elongated hole 321 can limit the sliding stroke and prevent the actuating part 3 from coming out.

[0039] Please refer to Figures 9 to 12. In one embodiment, the second fastener 2 and the actuating member 3 are respectively provided with a slide rail 23 and a slide groove 322 that slides and engages with the slide rail 23.

[0040] The sliding connection between the second fastener 2 and the actuating component 3 is simple and easy to assemble; the guide structure of the slide rail 23 and the slide groove 322 can provide a longer guide length, improve sliding stability, and reduce shaking noise.

[0041] Referring to Figures 5, 6, 10, and 11, in one embodiment, the elastic element 4 is a spring, a sheet, or a pad.

[0042] The type of elastic component 4 can be selected according to actual usage needs or production conditions. Springs, spring sheets, or spring pads are all mature standard parts, which can be flexibly selected according to cost, space and life requirements.

[0043] Please refer to Figures 3, 6, 8, 11 and 13. In one embodiment, the first fastener 1 is provided with a first magnetic element 12, and the second fastener 2 is provided with a second magnetic element 24.

[0044] The magnetic attraction of the first magnetic component 12 and the second magnetic component 24 facilitates the alignment of the first fastener 1 and the second fastener 2, and makes the connection between the first fastener 1 and the second fastener 2 more secure.

[0045] Referring to Figures 3, 8 and 13, in one embodiment, the first fastener 1 has a recessed first receiving cavity 15 on the side away from the second fastener 2, and the first magnetic member 12 is disposed in the first receiving cavity 15.

[0046] The first receiving cavity 15 embeds the magnetic component, preventing the first magnetic component 12 from directly colliding or being scratched by the outside world, which helps to extend the life of the first magnetic component 12 and maintain a flat appearance.

[0047] Referring to Figures 3, 8, and 13, in one embodiment, a first cover plate 16 is also included, which is connected to the first fastener 1 to close the first receiving cavity 15.

[0048] The first cover plate 16 seals the first receiving cavity 15 to prevent the first magnetic chuck 12 from falling off, while also preventing dust and sweat from entering and improving reliability.

[0049] Referring to Figures 3, 6 and 11, in one embodiment, the second fastener 2 has a recessed second receiving cavity 27 on the side away from the first fastener 1, and the second magnetic member 24 is disposed in the second receiving cavity 27.

[0050] The second receiving cavity 27 protects the second magnetic member 24 and makes the bottom surface of the second fastener 2 flat, so that it is comfortable to contact the skin when worn.

[0051] Referring to Figures 3, 6 and 11, in one embodiment, a second cover plate 28 is also included, which is connected to the second fastener 2 to close the second receiving cavity 27.

[0052] The second cover plate 28 prevents the second magnetic component 24 from falling off and from being corroded by sweat. It can also be decorated to enhance the overall aesthetics.

[0053] Referring to Figure 14, in one embodiment, the surface of the second fastener 2 away from the first fastener 1 is a convex arc surface 29.

[0054] The outer surface of the second fastener 2 is designed as a convex arc surface 29, which fits the curved surface of the wrist, reducing local pressure and making it more comfortable to wear.

[0055] Referring to Figures 1, 5, and 9, in one embodiment, the second fastener 2 is provided with a receiving groove 25, and at least a portion of the first fastener 1 is disposed in the receiving groove 25.

[0056] The receiving groove 25 causes the first fastener 1 to sink, which helps to reduce the overall thickness of the sliding connector, reduces the risk of snagging clothes, and makes the outer surface of the sliding connector flat after fastening, improving the aesthetics. In addition, the receiving groove 25 can reduce the risk of the first fastener 1 separating from the second fastener 2 due to external force.

[0057] Please refer to Figures 1, 3 to 9 and 12 to 14. In one embodiment, at least one of the first fastener 1 and the second fastener 2 is provided with a connecting hole 13.

[0058] At least one of the first fastener 1 and the second fastener 2 can be connected to other components through the connecting hole 13. The connecting hole 13 serves as a standard interface, eliminating the need for additional adapters and simplifying downstream assembly.

[0059] Referring to Figures 14 and 15, in one embodiment, at least one of the first fastener 1 and the second fastener 2 is provided with an ear portion 5, and the connecting hole 13 passes through the ear portion 5 along a first direction.

[0060] The ear portion 5 extends along the first direction, so that the axis of the connecting hole 13 is aligned with the first direction, resulting in more even force distribution.

[0061] Referring to Figures 5, 6, 9, and 11, in one embodiment, the second fastener 2 is provided with a limiting groove 26. The number of limiting grooves 26 is the same as the number of actuating members 3. The limiting grooves 26 and the actuating members 3 are arranged in a one-to-one correspondence. The actuating member 3 includes a hook 31 and a sliding part 32 connected together. The sliding part 32 is slidably connected to the second fastener 2, and the hook 31 is placed in the limiting groove 26.

[0062] Please refer to Figures 4 to 8, 11 and 12. In one embodiment, the first fastener 1 is provided with four limiting protrusions 14. The four limiting protrusions 14 are divided into two groups. The two limiting grooves 26 correspond one-to-one with the two groups of limiting protrusions 14. The mating part 11 is located between the two limiting protrusions 14 in the same group. The two end faces of the limiting protrusions 14 abut against the limiting grooves 26.

[0063] The limiting protrusion 14 abuts against the end face of the limiting groove 26, which can prevent the first fastener 1 from moving laterally relative to the second fastener 2, ensuring that the hook 31 and the mating part 11 are always aligned, reducing the risk of unlocking jamming.

[0064] Referring to Figures 6 and 7, Figures 11 and 12, in one embodiment, the limiting protrusion 14 is provided with an angled edge 141 at the end edge away from the first fastener 1.

[0065] The chamfer 141 at the end of the limiting protrusion 14 serves as an guide, automatically correcting minor offsets during engagement, improving engagement smoothness, and facilitating the insertion of the limiting protrusion 14 into the limiting groove 26.

[0066] Referring to Figure 9, in one embodiment, the sliding part 32 is provided with an anti-slip structure 324 on the side away from the hook 31.

[0067] The anti-slip structure 324 increases the coefficient of friction between the finger and the sliding part 32, allowing the user to reliably operate the device even when wearing gloves or sweating, thus improving the feel of operation.

[0068] Referring to Figure 7, in one embodiment, the hook 31 has a guide surface 311.

[0069] During the docking process of the first fastener 1 and the second fastener 2, the guide surface 311 abuts against the first fastener 1 to guide the sliding of the actuating member 3, thereby making it easier for the hook 31 to engage with the mating part 11.

[0070] A toggle connector for attaching watches, fashion wristbands, or belts, etc.

[0071] Referring to Figure 1, the toggle connector includes a first fastener 1, a second fastener 2, and two toggle members 3. The second fastener 2 is detachably connected to the first fastener 1. The toggle members 3 are slidably disposed on both sides of the second fastener 2 in a first direction and move between the locked position and the unlocked position in a second direction.

[0072] Referring to Figures 1 to 7, in some embodiments, the first fastener 1 is provided with two mating portions 11, and the two actuating members 3 are respectively engaged with the two mating portions 11. The two actuating members 3 are slidable relative to the second fastener 2 along a second direction to move closer to or away from the mating portions 11. The second direction is set at an angle of 45°-90° to the first direction. It also includes an elastic member 4, which is installed on the second fastener 2. The elastic member 4 is used to drive the actuating members 3 to move towards the mating portions 11 so that the first fastener 1 and the second fastener 2 remain locked.

[0073] In one or more embodiments, the toggle connector further includes an elastic element 4, which is configured to bias the toggle element 4 toward the locking position; the first fastener 1 and the second fastener 2 are detachably connected to prevent accidental contact in the following manner: when both toggle elements 3 are in the locking position, the two toggle elements 3 are simultaneously locked with the two mating parts 11 to prevent the first fastener 1 from disengaging relative to the second fastener 2 in the mating direction; the locking of the two toggle elements 3 is simultaneously released when and only when both toggle elements 3 overcome the bias of the elastic element 4 and move to the release position, allowing the first fastener 1 and the second fastener 2 to separate in the mating direction; wherein the movement trajectory of the two toggle elements 3 forms a non-zero angle with the mating direction.

[0074] This toggle connector connects the first fastener 1 and the second fastener 2 by engaging two toggle pieces 3 with two mating parts 11. When the connection between the first fastener 1 and the second fastener 2 is released, both toggle pieces 3 need to slide along the second direction to move away from the two mating parts 11, which effectively avoids the phenomenon of the first fastener 1 and the second fastener 2 being accidentally released due to the toggle pieces 3 being squeezed or collided by external forces.

[0075] Referring to Figures 1 and 2, in this embodiment, the second direction is perpendicular to the first direction. Referring to Figures 7 and 12, the first fastener 1 has an L-shaped groove that forms the mating part 11. Referring to Figures 5, 6, 9, and 11, the actuating member 3 includes a connected hook 31 and a sliding part 32. The sliding part 32 is slidably connected to the second fastener 2. The hook 31 is L-shaped and engages with the mating part 11. In other possible embodiments, the first fastener 1 has an L-shaped hook 31 that forms the mating part 11. It is also feasible for the actuating member 3 to have an L-shaped groove that engages with the mating part 11.

[0076] Referring to Figures 5 to 9 and Figures 11 to 13, the second fastener 2 is provided with a limiting groove 26. The number of limiting grooves 26 is the same as that of the actuating member 3, and the limiting grooves 26 and the actuating members 3 are arranged in a one-to-one correspondence. The L-shaped hook 31 of the actuating member 3 is placed in the limiting groove 26. The first fastener 1 is provided with limiting protrusions 14. Each limiting groove 26 is provided with a set of limiting protrusions 14, and there are two limiting protrusions 14 in each set. Two mating parts 11 are respectively arranged between the two limiting protrusions 14 in each set. The four limiting protrusions 14 abut against the two end faces of the two limiting grooves 26 respectively, thereby limiting the relative position of the first fastener 1 and the second fastener 2, so that the actuating member 3 is aligned with the mating part 11. In other words, in some embodiments, the first fastener 1 is provided with four limiting protrusions 14, and the four limiting protrusions 14 are divided into two groups. The two limiting grooves 26 correspond one-to-one with the two groups of limiting protrusions 14. The mating part 11 is located between the two limiting protrusions 14 in the same group, and the two end faces of the limiting protrusions 14 and the limiting grooves 26 abut against each other, as shown in FIG4.

[0077] Please refer to Figures 7 and 12. The edge of the limiting protrusion 14 away from the first fastener 1 is provided with an angled corner 141 so that the limiting protrusion 14 can be inserted into the limiting groove 26.

[0078] Referring to Figures 6 and 11, the second fastener 2 has mounting holes 21 on both sides in the first direction, and the actuating member 3 is disposed in the mounting holes 21. Specifically, the mounting holes 21 connect the side of the second fastener 2 in the first direction and the limiting groove 26. The sliding part 32 of the actuating member 3 is disposed in the mounting holes 21. The width of the mounting holes 21 in the second direction is greater than the width of the sliding part 32 in the second direction. Both the mounting holes 21 and the sliding part 32 are oblong.

[0079] Referring to Figure 9, in a preferred embodiment, the sliding part 32 is provided with an anti-slip structure 324 on the side away from the hook 31. The anti-slip structure 324 is used to increase the coefficient of friction of the surface of the sliding part 32 in contact with the user's hand, so as to facilitate the user to slide the toggle member 3.

[0080] Referring to Figures 5 and 6, the second fastener 2 and the actuating member 3 are respectively provided with a pin 22 and an elongated hole 321 that slides with the pin 22. Specifically, the pin 22 is mounted on the second fastener 2, and the sliding part 32 of the actuating member 3 has an elongated hole 321. The pin 22 is cylindrical, and its axial direction is perpendicular to both the first and second directions. The elongated hole 321 is oblong, and its length direction is parallel to the second direction. In other embodiments, it is also feasible for the pin 22 to be mounted on the actuating member 3 and the elongated hole 321 to be formed on the second fastener 2.

[0081] Please refer to Figures 5, 6, 10, and 11. The number of elastic elements 4 and actuating elements 3 are arranged in a one-to-one correspondence. It is easy to understand that when one actuating element 3 is subjected to force and slides away from the mating part 11, the elastic element 4 corresponding to the other actuating element 3 is not affected. At this time, the elastic element 4 still drives the other actuating element 3 to engage with the mating part 11, preventing the first fastener 1 and the second fastener 2 from accidentally disengaging.

[0082] In this embodiment, the elastic element 4 is a spring, and the axial direction of the elastic element 4 is parallel to the second direction. The two ends of the elastic element 4 abut against the side of the mounting hole 21 away from the mating part 11 and the sliding part 32, respectively. In other embodiments, the elastic element 4 may be a spring sheet or a spring pad.

[0083] Referring to Figures 5, 6, 10, and 11, in this embodiment, the sliding portion 32 of the actuating member 3 is provided with a limiting portion 323, and the end of the elastic member 4 is limited by the limiting portion 323. In other embodiments, the second fastener 2 is provided with a limiting portion 323 to accommodate the end of the elastic member 4. In this embodiment, the limiting portion 323 is a limiting hole; in other embodiments, the limiting portion 323 is a limiting block.

[0084] Referring to Figures 3, 6, 8, 11, and 13, the first fastener 1 is provided with a first magnetic accommodating element 12, and the second fastener 2 is provided with a second magnetic accommodating element 24. The first fastener 1 has a recessed first receiving cavity 15 on its side away from the second fastener 2, and the first magnetic accommodating element 12 is disposed within the first receiving cavity 15. The actuating connector also includes a first cover plate 16, which is connected to the first fastener 1 to close the first receiving cavity 15. The second fastener 2 has a recessed second receiving cavity 27 on its side away from the first fastener 1, and the second magnetic accommodating element 24 is disposed within the second receiving cavity 27. The actuating connector also includes a second cover plate 28, which is connected to the second fastener 2 to close the second receiving cavity 27. The magnetic connection of the first magnetic accommodating element 12 and the second magnetic accommodating element 24 facilitates the alignment of the first fastener 1 and the second fastener 2 and makes the connection between the first fastener 1 and the second fastener 2 more secure.

[0085] In one or more embodiments, the outer surface of the hook 31 is provided with a guide surface 311, which is an arc surface or a slope surface. When the guide surface 311 abuts against the first fastener 1, as the distance between the first fastener 1 and the second fastener 2 gets closer and closer, the first fastener 1 will push the hook 31 to the unlock position through the guide surface 311, thereby making the hook 31 and the mating part 11 form a locking engagement. That is to say, during the locking process of the first fastener 1 and the second fastener 2, the user does not need to operate the toggle 3, but only needs to push one of the first fastener 1 and the second fastener 2 along the docking direction of the two, which is convenient for the user and helps to enhance the user experience.

[0086] In some embodiments, the cooperation of the first magnetic clasp 12 and the second magnetic clasp 24 causes the first fastener 1 and the second fastener 2 to attract each other and move closer together, thereby making it easier for the user to connect the first fastener 1 and the second fastener 2. In fact, no force is required during the connection process of the first fastener 1 and the second fastener 2; simply aligning the first fastener 1 and the second fastener 2 is sufficient. Under the cooperation of the first magnetic clasp 12 and the second magnetic clasp 24, the first fastener 1 and the second fastener 2 will automatically connect.

[0087] Referring to Figures 5 to 7, 9, 11, and 12, the second fastener 2 has a receiving groove 25, and at least a portion of the first fastener 1 is disposed within the receiving groove 25. Specifically, a limiting groove 26 is disposed at the bottom of the receiving groove 25, and the depth of the receiving groove 25 is equal to the thickness of the first fastener 1. In other embodiments, it is also feasible for the depth of the receiving groove 25 to be less than the thickness of the first fastener 1.

[0088] Locking process: The first fastener 1 and the second fastener 2 are brought closer to each other along the docking direction, which is perpendicular to both the first and second directions. During the approaching process, the first magnetic attractor 12 and the second magnetic attractor 24 first generate a pre-attractive force, which guides the limiting protrusion 14 of the first fastener 1 into the limiting groove 26 of the second fastener 2. At the same time, the lower surface of the first fastener 1 is in contact with the bottom surface of the receiving groove 25, thus completing the initial positioning in three directions. Subsequently, the mating part 11 of the first fastener 1 continues to approach the hook 31 of the actuating member 3 in the third direction. The guide surface 311 of the hook 31 is pressed, and its wedging force is decomposed into a component force in the second direction, pushing the actuating member 3 to slide in the mounting hole 21. The elongated hole 321 moves relative to the pin 22 and compresses the elastic member 4. When the hook 31 passes the wedging point of the mating part 11, the elastic member 4 is released, the actuating member 3 rebounds, and the hook 31 is engaged in the mating part 11, realizing mechanical locking. The first magnetic suction member 12 and the second magnetic suction member 24 maintain the attraction in the docking direction, and the elastic member 4 provides positive pressure in the second direction. The two together prevent the first fastener 1 and the second fastener 2 from disengaging in the docking direction, and the locking is completed.

[0089] Unlocking process: Simultaneously move the actuating parts 3 on both sides of the second fastener 2 along the second direction, causing the actuating parts 3 to slide along the mounting hole 21. The elongated hole 321 shifts relative to the pin 22, reducing the engagement amount between the hook 31 and the mating part 11 to zero. While maintaining the actuation state, pull the first fastener 1 and the second fastener 2 apart in the opposite direction of the mating direction. The limiting protrusion 14 exits the limiting groove 26, and the increased distance between the first magnetic suction part 12 and the second magnetic suction part 24 causes a sudden decrease in the suction force, allowing the first fastener 1 and the second fastener 2 to separate smoothly. After releasing the actuation force, the elastic element 4 pushes the actuating part 3 back to its original position. The pin 22 engages with the end face of the elongated hole 321 to prevent excessive movement, and the unlocking process ends.

[0090] Referring to Figure 3, at least one of the first fastener 1 and the second fastener 2 is provided with a connecting hole 13. In some embodiments, the connecting hole 13 on the first fastener 1 is located on one side of the first fastener 1 in the second direction, and the connecting hole 13 on the second fastener 2 is located on the side of the second fastener 2 away from the connecting hole 13 on the first fastener 1. The first fastener 1 and the second fastener 2 can be connected to other components through the connecting holes 13 respectively.

[0091] Referring to Figures 9 to 11, in one or more embodiments, the second fastener 2 and the actuating member 3 are respectively provided with a slide rail 23 and a groove 322 that slides and engages with the slide rail 23. Specifically, the slide rail 23 is mounted on the second fastener 2, and the sliding portion 32 of the actuating member 3 has a groove 322. The slide rail 23 extends along a second direction. The groove 322 connects the bottom surface of the sliding portion 32 of the actuating member 3 and its two sides along the second direction. In other embodiments, it is also feasible for the slide rail 23 to be mounted on the actuating member 3 and the groove 322 to be formed on the second fastener 2.

[0092] Referring to Figure 14, in one or more embodiments, the surface of the second fastener 2 away from the first fastener 1 is a convex arc surface 29. In some embodiments, the second cover plate 28 is an arc plate to form the convex arc surface 29.

[0093] Referring to Figures 14 and 15, in this embodiment, in some embodiments, at least one of the first fastener 1 and the second fastener 2 is provided with an ear portion 5, and the connecting hole 13 passes through the ear portion 5 along a first direction. The ear portion 5 on the first fastener 1 is less than or equal to the length of the body of the first fastener 1, and the ear portion 5 on the second fastener 2 is less than or equal to the length of the receiving groove 25 on the second fastener 2. In some embodiments, the length of the ear portion 5 on the first fastener 1 is equal to or approximately equal to the length of the ear portion 5 on the second fastener 2.

[0094] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent modifications made based on the content of this application's specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this application.
