Abstract
Description
Technical Field
[0001] This application belongs to the field of wearable product accessories technology, and in particular relates to a magnetic connecting strap. Background Technology
[0002] In existing wearable product connecting straps, during use, a first strap body is typically fixed with a fastener and a movable hoop. The fastener has an insert rod, and a second strap body has several strap holes. The second strap body is first inserted into the fastener, and then the insert rod of the fastener is selectively inserted into one of the strap holes of the second strap body to complete the fixation. Then, the excess length of the free end of the second strap body is inserted into the hoop on the first strap body for restriction. This makes the user feel cumbersome and inconvenient. Utility Model Content
[0003] The purpose of this application is to provide a magnetic connecting strap, which aims to solve the technical problem of cumbersome use and operation of existing wearable product connecting straps.
[0004] To achieve the above objectives, the present application adopts a technical solution as follows: a magnetic connecting strip, comprising a first strip body and a second strip body, the first strip body being provided with a magnetic element and a strip hole, the second strip body being provided with a limiting element and an attracting element, at least a portion of the limiting element being able to be inserted into the strip hole, the magnetic element and the attracting element being able to magnetically attract each other, and when the magnetic element and the attracting element attract each other, the first distance between the magnetic element and the attracting element does not exceed 5mm.
[0005] Optionally, the first distance between the magnetic element and the attracting element is 0.1mm-4mm; or, the first distance between the magnetic element and the attracting element is 0.3mm-4mm; or, the first distance between the magnetic element and the attracting element is 0.5mm-4mm; or, the first distance between the magnetic element and the attracting element is 0.8mm-4mm.
[0006] Optionally, the attracting element is not magnetic, but can be magnetically attracted by the magnetic element.
[0007] Optionally, at least two suction elements are provided, and each suction element is spaced apart along the length direction of the second belt; the second distance between two adjacent suction elements is not less than the thickness of the suction element;
[0008] And / or, the second distance between two adjacent suction elements does not exceed 8 mm.
[0009] Optionally, the magnetic element is elongated and its length along the width direction of the first strip is at least half the width of the first strip.
[0010] And / or, the suction element is elongated along the width direction of the second belt, and the length of the suction element is at least half the width of the second belt.
[0011] Optionally, the magnetic element is in the shape of a short strip, and at least two magnetic elements are arranged at intervals along the width direction of the first strip;
[0012] And / or, the suction element is in the shape of a short strip, and at least two of the suction elements are arranged at intervals along the width direction of the second belt.
[0013] Optionally, the end of the limiting member is provided with a cap, which can prevent the limiting member from disengaging from the hole.
[0014] Optionally, the size of the limiting member is 0.8-1.2 times the size of the hole.
[0015] Optionally, at least a portion of the first strip and / or the second strip is made of a soft material.
[0016] Optionally, at least a portion of the first belt and / or the second belt is made of a rigid material.
[0017] The advantages of the magnetic connecting strip provided in this application compared with the prior art are as follows:
[0018] The magnetic connecting strip of this application enables magnetic attraction between the magnetic components and the attracting component between the first and second strip bodies, allowing them to be magnetically connected. At least a portion of the limiting component protrudes from the outside of the second strip body, facilitating its insertion into the corresponding hole in the first strip body. This limiting component effectively restricts slippage between the first and second strip bodies, significantly improving the stability of the connection between them.
[0019] When using the product, the user pre-connects the first and second straps to the two connection points on the wearable device. During daily use, the user simply inserts the retaining piece of the second strap into one of the holes in the first strap, then brings the first and second straps close together to attract them magnetically, completing the wearing process. It's very convenient and cumbersome. To remove the product, simply pry open the connection between the first and second straps with a little force.
[0020] When attracting, the magnetic component and the attracting component can be in direct contact, creating a strong attraction between them and ensuring the stability of the connection between the first and second belts. Alternatively, a soft buffer can be placed between the magnetic component and the attracting component, maintaining an effective magnetic attraction distance. This prevents rigid direct contact between the two components during attraction, creating a soft contact and reducing the risk of accidental injury to the user due to instantaneous magnetic attraction.

[0034] The embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-10 The described embodiments are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0035] In the description of this application, it should be understood that the terms "near", "far", "length", "width", "thickness", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0037] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0038] The following describes the fixing strap and wearable product wristband provided in the embodiments of this application. Wearable products can be mechanical devices, electronic devices, smart devices, medical devices, monitoring devices, beauty devices, or other products worn on the human body or animals, and will not be listed exhaustively here.
[0039] like Figure 1 , Figure 5 , Figure 9 and Figure 10 As shown, this application embodiment provides a magnetic connecting strip, including a first strip body 10 and a second strip body 20. The first strip body 10 is provided with a magnetic element 11 and a strip hole 12. The second strip body 20 is provided with a limiting element 21 and an attracting element 22. At least a portion of the limiting element 21 can be inserted into the strip hole 12. The magnetic element 11 and the attracting element 22 can magnetically attract each other. When the magnetic element 11 and the attracting element 22 attract each other, the first distance D1 between the magnetic element 11 and the attracting element 22 does not exceed 5mm.
[0040] Compared with the prior art, the magnetic connecting strip provided in this application embodiment allows for magnetic attraction between the magnetic element 11 and the attraction element 22 between the first strip body 10 and the second strip body 20, thus enabling a strong magnetic connection between them. At least a portion of the limiting element 21 protrudes from the outside of the second strip body 20, facilitating its insertion into the corresponding hole 12 in the first strip body 10. This effectively restricts slippage between the first strip body 10 and the second strip body 20, significantly improving the stability of the connection between them.
[0041] When using the product, the user pre-connects the first strap 10 and the second strap 20 to the two connection points on the wearable device. During daily use, the user simply inserts the limiting piece 21 of the second strap 20 into one of the holes 12 of the first strap 10, then brings the first strap 10 and the second strap 20 close together to attract them magnetically, completing the wearing process. It is very convenient and cumbersome. To remove the wearable device, simply pry open the connection between the first strap 10 and the second strap 20 with a little force.
[0042] When the magnetic component 11 and the attracting component 22 attract each other, they can be in direct contact, resulting in a strong attraction between them and ensuring the connection stability between the first belt 10 and the second belt 20. Figure 10As shown, a soft buffer can also be provided between the magnetic component 11 and the attracting component 22, with an appropriate distance between them to maintain an effective magnetic attraction distance. This prevents the magnetic component 11 and the attracting component 22 from having rigid direct contact during attraction, forming a certain soft contact and reducing the risk of accidental pinching of the user due to the instantaneous attraction of magnetic force. The first distance D1 generally does not exceed 5mm, and can be within 5mm, 4mm, 3mm, 2mm, 1mm, 0.5mm, 0.1mm-1mm, 0.1mm-2mm, 0.1mm-3mm, 0.2mm-4mm, 0.3mm-5mm, 0.4mm-5mm, 0.5mm-5mm, etc., as needed. This can effectively maintain the attraction between the magnetic component 11 and the attracting component 22 and maintain the connection stability between the first belt 10 and the second belt 20.
[0043] The attracting element 22 may be magnetic, or it may not be magnetic but may be attracted by a magnet, so that regardless of whether the attracting element 22 is magnetic, it can be magnetically attracted to the magnetic element 11.
[0044] In some implementations, such as Figure 10 As shown, when the magnetic component 11 and the attracting component 22 are connected by attraction, the first distance D1 between them can be 0.1mm-4mm; or, the first distance D1 between them can be 0.3mm-4mm; or, the first distance D1 between them can be 0.5mm-4mm; or, the first distance D1 between them can be 0.8mm-4mm. These distance ranges allow for a certain space between the magnetic component 11 and the attracting component 22 to accommodate a soft buffer, maintaining an effective magnetic attraction distance, reducing rigid direct contact between them, forming a certain soft contact, reducing the possibility of accidental injury to the user due to instantaneous magnetic attraction, and maintaining the connection stability between the first belt 10 and the second belt 20.
[0045] In some embodiments, the attracting element 22 is non-magnetic, but can be magnetically attracted by the magnetic element 11. The attracting element 22 is made of a magnetically attractive material. This effectively ensures that when the first strip 10 or the second strip 20 is flipped to different sides, the attracting element 22 and the magnetic element 11 can maintain good magnetic attraction, and the first strip 10 and the second strip 20 can be well aligned and fitted together, making it convenient to use. If the attracting element 22 is magnetic, magnetic pole interference may easily occur between the attracting element 22 and the magnetic element 11. When the first strip 10 or the second strip 20 is flipped to different sides, there will be no repulsive force between like poles, preventing the first strip 10 and the second strip 20 from failing to align and fit together. The material of the attracting element 22 is a conventional magnetically attractive metal, such as iron or stainless steel, which will not be listed here.
[0046] In some implementations, such as Figure 6 , Figure 7 and Figure 8 As shown, at least two suction members 22 are provided, and each suction member 22 is spaced apart along the length direction of the second belt 20. Figure 6 As shown, in one embodiment, the second distance D2 between two adjacent suction members 22 is not less than the thickness S of the suction member 22. This can minimize the mutual interference between the two adjacent suction members 22 when the second band 20 is bent, effectively reducing the influence of the suction member 22 on the flexibility of the second band 20 when it bends. As a result, the second band 20 can better fit the user's body surface, such as the wrist, and is more comfortable to wear.
[0047] The thickness direction of the suction element 22 is the same as that of the belt body, and the same applies below.
[0048] In another approach, when the thickness S of the attracting element 22 is less than 8 mm, the second distance D2 between two adjacent attracting elements 22 is between the thickness S and 8 mm of the attracting element 22. By limiting the distance between two adjacent attracting elements 22 to this range, the user experience can be improved, and the effect of the magnetic connection between the first belt 10 and the second belt 20 can be reduced due to the large distance between two adjacent attracting elements 22.
[0049] In another approach, the second distance D2 between two adjacent attracting elements 22 does not exceed 8mm. By limiting the distance between two adjacent attracting elements 22 to this range, the user experience can be improved, and the effect of magnetic connection between the first belt 10 and the second belt 20 can be reduced due to the excessive distance between two adjacent attracting elements 22.
[0050] It should be noted that the "first distance" (Figure D1) and "second distance" (Figure D2) in this application refer to the straight-line distance between the two points that are closest to each other between two objects.
[0051] In some implementations, such as Figure 3 As shown, the magnetic element 11 is elongated along the width direction of the first strip 10, and the length of the magnetic element 11 is at least half the width of the first strip 10; and / or, as shown Figure 7 As shown, the suction member 22 is elongated and extends along the width direction of the second belt 20. The length of the suction member 22 is at least half the width of the second belt 20. The length of the suction member 22 can be set as needed. The direction in which the length of the suction member 22 extends is the width direction of the second belt 20 (i.e., the direction perpendicular to the length of the second belt 20, the same below). The length of the suction member 22 can be at least half the width of the second belt 20, or it can be less than half the width of the second belt 20.
[0052] like Figure 7 As shown, when only one attraction member 22 is provided in the width direction of the second belt 20, the attraction member 22 can be located in the middle or other positions in the width direction of the second belt 20. The length of the magnetic member 11 can be set as needed. The direction in which the length of the magnetic member 11 extends is the width direction of the first belt 10 (i.e., the direction perpendicular to the length of the first belt 10, the same below). The length of the magnetic member 11 corresponds to the length of the attraction member 22. The length of the magnetic member 11 and the length of the attraction member 22 are approximately the same, and the position of the magnetic member 11 corresponds to the position of the attraction member 22, so that when the magnetic member 11 and the attraction member 22 attract each other, the first belt 10 and the second belt 20 can be aligned.
[0053] In some implementations, such as Figure 8 As shown, the suction element 22 is in the shape of a short strip, and the length of the suction element 22 is less than half the width of the second belt 20. At least two suction elements 22 are arranged at intervals along the width direction of the second belt 20; and / or, as shown Figure 4 As shown, the magnetic element 11 is in the shape of a short strip, and the length of the magnetic element 11 is less than half the width of the first strip 10. At least two magnetic elements 11 are arranged at intervals along the width direction of the first strip 10.
[0054] One implementation method is as follows: Figure 8 As shown, two short, strip-shaped suction elements 22 are symmetrically arranged near both sides of the second belt body 20, such as... Figure 3As shown, the first strip 10 has a long strip-shaped magnetic element 11. The length of the magnetic element 11 is such that the two magnetic poles of the magnetic element 11 correspond to the positions of the two attraction elements 22. When the first strip 10 is connected to the second strip 20, the magnetic force of the magnetic element 11 is at its maximum when it is at the magnetic pole position, so that the two short strip-shaped attraction elements 22 are naturally attracted to the corresponding magnetic pole positions of the magnetic element 11. This allows the first strip 10 and the second strip 20 to be well aligned and overlapped without any offset or sticking, resulting in good performance.
[0055] Another implementation method is: such as Figure 4 As shown, two magnetic elements 11 are symmetrically arranged near the two sides of the first strip 10, such as... Figure 8 As shown, two attraction elements 22 are symmetrically arranged near the two sides of the second band 20. When the first band 10 and the second band 20 are connected, the magnetic elements 11 and attraction elements 22 at corresponding positions attract each other, ensuring good alignment and overlap between the first band 10 and the second band 20 without any misalignment. Furthermore, by arranging two short, strip-shaped magnetic elements 11 at intervals on the first band 10, the flexibility of the first band 10 in the width direction is improved, allowing it to bend in that direction. Similarly, by arranging two short, strip-shaped attraction elements 22 at intervals on the second band 20, the flexibility of the second band 20 in the width direction is improved, allowing it to bend in that direction as well. This allows the first band 10 and the second band 20 to better conform to the user's body surface (e.g., wrist), reducing any stiff or uncomfortable feeling, resulting in greater comfort and better performance.
[0056] Another implementation method is: such as Figure 4 As shown, two short strip-shaped magnetic elements 11 are symmetrically arranged near the two sides of the first strip body 10, such as... Figure 7 As shown, the second belt 20 has a long strip-shaped attracting element 22. The length of the attracting element 22 is sufficient to be directly aligned with the two magnetic elements 11. Thus, when the first belt 10 is connected to the second belt 20, the constraint of the first belt 10 itself on the two magnetic elements 11 allows the two short strip-shaped magnetic elements 11 to naturally attract the two ends of the attracting element 22, thereby ensuring that the first belt 10 and the second belt 20 are well aligned and overlapped without any offset or misalignment, resulting in good performance.
[0057] In some embodiments, the end of the limiting member 21 is provided with a cap (not shown), which can prevent the limiting member 21 from disengaging from the belt hole 12. The area around the belt hole 12 can elastically deform. When the first belt body 10 and the second belt body 20 are connected, the limiting member 21 of the second belt body 20 is inserted into the belt hole 12 from one side of the first belt body 10 and passes through the other side, so that the cap can pass through the belt hole 12 and engage with the first belt body 10, thereby appropriately limiting the limiting member 21 from disengaging from the belt hole 12, thus improving the stability of the connection between the first belt body 10 and the second belt body 20. When it is necessary to separate the first belt body 10 and the second belt body 20, it is only necessary to slightly pry them apart so that the limiting member 21 disengages from the belt hole 12, which is convenient to use.
[0058] In some implementations, such as Figure 9 As shown, the size of the limiting member 21 is 0.8-1.2 times the size of the hole 12. The limiting member 21 and the hole 12 can be interference-fitted, clearance-fitted, or fit perfectly together; that is, the size of the limiting member 21 can be slightly larger than the size of the hole 12, slightly smaller than the size of the hole 12, or equal to the size of the hole 12. The limiting member 21 can be inserted partially into the hole 12, without needing to completely pass through to the other side; of course, the limiting member 21 can also completely pass through to the other side of the hole 12. The limiting member 21 and the hole 12 are such that the limiting member 21 is inserted into the hole 12, thereby restricting the sliding between the first belt body 10 and the second belt body 20 in the length and / or width directions.
[0059] In some embodiments, at least a portion of the first strap 10 and / or the second strap 20 is made of a soft material. The material used to make at least a portion of the first strap 10 and / or the second strap 20 can be a soft material, including but not limited to: various fabrics, various leathers, various synthetic materials, rubber, silicone, etc., or any combination thereof. Straps made of soft materials can provide users with a good wearing experience, being soft, comfortable, and easy to use.
[0060] In some embodiments, at least a portion of the first strap 10 and / or the second strap 20 is made of a rigid material. The material used to make at least a portion of the first strap 10 and / or the second strap 20 can be a rigid material, including but not limited to: various metals, plastics, and any combination of other synthetic materials. Straps made of rigid materials, such as chains or cartoon buckles, provide users with a good sense of texture and aesthetics, making them suitable for different occasions and easy to wear.
[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
