Description

Technical Field

[0001] The present application relates to the field of mechanics, and in particular to a device with a fastener and an installation method. Background Art

[0002] With the development of science and technology, smart wearable devices are widely used in daily life. While smart wearable devices provide consumers with application convenience, consumers also have many demands on the wearing experience of smart wearable devices. Taking smart wearable watches as an example, when using the clasp, it is hoped that the clasp has a rebound function, that is, the clasp automatically returns to its original position after being folded, thereby improving the user's convenience. The existing clasp realizes the rebound of the clasp by setting a spring inside, but there are problems with complex assembly and high cost. Therefore, it is necessary to provide a device with a buckle that can achieve the effect of simple assembly and relatively low cost under the rebound effect of the buckle. Summary of the Invention

[0003] The embodiment of the present application provides a device with a fastener, which greatly simplifies the assembly difficulty and reduces costs.

[0004] In the first aspect, an embodiment of the present application provides a device with a fastener, comprising: a main body with a limiting structure, a fastener and a rebound component; the fastener comprises a buckle tongue and a buckle body, and the buckle body is movably connected to the main body; one end of the rebound component is placed in the limiting structure, and the other end is connected to the buckle body; the limiting structure is used to limit the rebound component when the buckle body is subjected to force; the rebound component is used to rebound the buckle body after the force on the buckle body is released.

[0005] In the above design, the buckle device includes a main body with a limiting structure, a buckle, and a rebound component. The two ends of the rebound component are connected to different components respectively. One end of the rebound component is placed in the limiting structure, that is, connected to the main body; the other end is fixed to the buckle body. The limiting structure on the main body is used to limit the rebound component when the buckle body is subjected to force; the rebound component is used to rebound the buckle body after the force is released. That is to say, when the buckle body is flipped over by the force, it automatically rebounds through the rebound component after the force is removed, allowing the buckle body to return to its original position. Compared with the existing technology, there is no need to fix one end of the ear and assemble through the other end. At the same time, there is no need to change the internal components of the buckle for assembly. Only simple component assembly is required, which has low process requirements and effectively reduces costs.

[0006] In one possible design, the fastener also includes a link; the main body is provided with a first through hole; the buckle tongue is provided with a second through hole; the link passes through the first through hole and the second through hole to connect the main body and the buckle tongue; one end of the rebound component is placed in the limiting structure and connected to the link, and the other end is embedded in the buckle body.

[0007] In the above design, the fastener also includes a link. A first through hole is provided in the main body for the link to pass through. A second through hole is provided on the buckle tongue, which is also for the link to pass through. The link fixes the main body and the buckle tongue by passing through the first through hole and the second through hole. The rebound component is built into the limiting structure and fixedly connected to the link, and the other end of the rebound component is embedded in the buckle body of the fastener. The limiting structure and the buckle body fix the rebound component, and after it flips after being subjected to force, it can automatically rebound after the force is removed. This assembly method is simple and easy to operate.

[0008] In a possible design, the buckle body is provided with a slot, and the other end of the resilient component is embedded in the slot.

[0009] In the above design, the specific way in which the other end of the rebound component is embedded in the buckle body is: a slot is provided in the buckle body, and the other end of the rebound component is installed in the slot of the buckle body, thereby realizing an installation method in which the slot and the rebound component match each other, which is simple to operate and has low process requirements.

[0010] In a possible design, the limiting structure is made of a hard material; the limiting structure is built into the body and has a third through hole corresponding to the first through hole; and the link passes through the third through hole.

[0011] In the above design, the limiting structure is used to limit the rebound component to achieve the rebound effect. Therefore, when deformation occurs under force, in order to achieve the rebound effect, it is necessary to ensure that the limiting structure is made of hard material. Hard material will not buffer the force, effectively ensuring the rebound effect. The limiting structure is built into the main body, and its internal hollow design has a third through hole corresponding to the first through hole, which is used for the link to achieve built-in passage.

[0012] In a possible design, a protrusion is provided on the surface of the limiting structure, and a groove corresponding to the protrusion is provided inside the body.

[0013] In the above design, a protrusion is formed on the surface of the limiting structure, and a groove is formed at the corresponding position inside the strap. This is to prevent the limiting structure built into the body from loosening after long-term use, thereby increasing its service life.

[0014] In a possible design, the limiting structure is integrally formed with the body.

[0015] The limiting structure is arranged in the main body, and the main body is formed by injection molding. The limiting structure and the main body are integrally formed, which effectively ensures the accuracy of matching between the limiting structure and the rebound component and better adapts to the shape of the rebound component.

[0016] In a possible design, the device is a watch, the body is a watch strap, the link of the buckle is a spring ear, and there are two rebound components, which are respectively arranged at both ends of the spring ear.

[0017] In the above design, when the device is a watch, the main body is a watch strap, the connecting part of the buckle is a spring ear, and two rebound components are provided, which are respectively located at the two ends of the spring ear, so as to effectively fix the main body and the buckle body and achieve a rebound effect.

[0018] In a possible design, the rebound component is a torsion spring; the rebound component is sleeved on the link component.

[0019] In the above design, the rebound component is a torsion spring, a variation of a spring with a hollow center. It is placed over the link and connects the body and the buckle. When applied with force, it deforms. When the force is removed, the torsion spring automatically rebounds, enhancing the watch's convenience and playability.

[0020] On the second aspect, an embodiment of the present application provides a method for installing a fastener, including: step 1, fixing the limiting structure in the main body; step 2, after passing the link of the fastener through the main body, placing the rebound components from both ends of the link into the limiting structure of the main body; step 3, fixing the other end of the rebound component on the buckle body.

[0021] In the aforementioned design, the fastener assembly method first incorporates a limit structure within the main body to securely restrain the resilient component. Next, the fastener's link is passed through the main body, with resilient components attached to each end of the link. One end of the resilient component is placed within the main body's limit structure, while the other end is secured to the fastener, completing the assembly connection between the fastener and the main body. Compared to existing assembly methods, this eliminates the need for modifying the link, significantly reducing assembly difficulty and cost.

[0022] In one possible design, after the link of the fastener is passed through the main body, the rebound components are placed in the limiting structure of the main body from both ends of the link, including: the main body is provided with a first through hole; the buckle tongue is provided with a second through hole; the link is passed through the first through hole and the second through hole; one end of the rebound component is placed in the limiting structure and connected to the link, and the other end is embedded in the buckle body.

[0023] In the above design, the specific assembly method is to provide a first through-hole in the body and a second through-hole in the buckle tongue. After the link is passed through the first and second through-holes, a resilient component is inserted into both ends of the link. One end of the resilient component is placed in the retaining structure and connected to the link, while the other end is embedded in the buckle body. Ultimately, the body and the buckle are connected and assembled, providing convenience, reducing process requirements, and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the objectives, technical solutions, and advantages of this application more clear, this application will be further described in detail below with reference to the accompanying drawings. It is obvious that the embodiments described are only some of the embodiments of this application, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application without making any creative efforts shall fall within the scope of protection of this invention.

[0032] The application scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Persons skilled in the art will appreciate that as new application scenarios emerge, the technical solutions provided by the embodiments of the present invention will also be applicable to similar technical problems. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0033] The components used in wearable devices have a rebound function, which can greatly reduce the chance of deformation and damage due to overload, and achieve a quick recovery effect. Taking wearable watches as an example, in order to achieve this rebound effect, existing solutions, such as Figure 1As shown, the assembly process is achieved by hollowing out the interior of the ear 101, installing a spring 102, and connecting the two ends of the spring to the left and right support structures (103, 104) respectively, and the left and right support structures (103, 104) are connected and fixed to the clasp 105. The ear refers to the connecting steel rod that fixes the watchband and the watch dial, which is used to achieve the linking effect. When the clasp is overturned by an external force, the spring deforms. When the external force is removed, the spring recovers its deformation, achieving a rebound effect on the clasp. In the existing solution, the ear needs to be modified twice, that is, the ear is hollowed out, an elastic component is built in, and then connected to the support structure, and finally connected and fixed to the clasp. In this process, the interior of the ear is first hollowed out, which requires a relatively difficult process. At the same time, the spring is built in and connected to the support structure before the clasp is fixed, which makes the assembly difficult and the cost relatively high.

[0034] Based on this, an embodiment of the present application provides a device with a buckle to achieve a rebound function and reduce assembly difficulty and cost.

[0035] There are many kinds of devices with buckles, which can be watches, belts, or bag straps, etc. The following is an introduction using a watch as an example.

[0036] Figure 2 An overall diagram of a device with a buckle is provided for an embodiment of the present application. Figure 2 The illustrated device with a buckle includes a body 100 with a limiting structure, a buckle 200, and a resilient component 300 (only the position is shown in the figure); the buckle 200 includes a tongue 202 and a buckle body 201, which is movably connected to the body 100; one end of the resilient component 300 is placed in the limiting structure and the other end is connected to the buckle body 201; the limiting structure is used to limit the resilient component 300 when the buckle body 201 is subjected to force; the resilient component 300 is used to rebound the buckle body 201 after the force is released. Specifically for a watch, the body 100 is a watch strap; the connecting member 203 of the buckle 200 is a spring ear; and there are two resilient components 300, one at each end of the spring ear.

[0037] Among them, the rebound component 300 is the basis for realizing the rebound of the device. One end is connected and fixed to the body 100 with the limiting structure, and the other end is connected and fixed to the buckle 200. Figure 4 As shown, Figure 4 The present invention provides a side view of a device having a buckle. In the initial state, the resilient component 300 controls the buckle body 201 to contact the outer surface of the body 100, that is, the resilient component 300 is subjected to force to tighten the buckle body 201. During use, the buckle body 201 receives an external force F and flips over. After the external force F is removed, the resilient component 300 generates a rebound force F1 opposite to the external force F, causing the buckle to rebound, thus achieving the rebound effect of the buckle. The calculation formula for F1 is:

[0038]

[0039] Where E is the modulus of the rebound component; d is the wire diameter, is the twist angle; n is the number of effective turns; D is the median diameter; and L is the swing arm length. The above calculations show that a 120° twist generates approximately 0.5N. When there are a large number of rebound components, they are continuously superimposed, achieving automatic rebound.

[0040] It should be noted that one end of the resilient component 300 is connected to the body 100 by a limiting structure in the body 100. The other end can be connected to the buckle body 201 in various ways, such as direct adhesion, embedding into the buckle body 201, or other connection methods, which are not limited here.

[0041] by Figure 3 Take the smart wearable watch shown as an example, Figure 3 An internal schematic diagram of a device with a buckle is provided for an embodiment of the present application, namely Figure 2 Specifically, the buckle 200 further includes a link 203; the body 100 is provided with a first through-hole 101; the tongue 202 is provided with a second through-hole 2021; the link 203 passes through the first through-hole 101 and the second through-hole 2021; one end of the resilient component 300 is placed in the limiting structure and connected to the link 203, and the other end is embedded in the buckle body 201.

[0042] It should be noted that the buckle tongue 202 can be implemented in various ways. It can be a needle buckle in the embodiment of the present application or a hook buckle, and this is not limited here.

[0043] Regarding the assembly process of the buckle and the body, specifically, the link 203 can be first passed through the first through hole 101 on the body and the second through hole 2021 on the buckle tongue 202, and then the resilient component 300 and the link 203 are assembled. Then, the resilient component 300 is fixed to the limiting structure of the body 100, and finally fixed to the buckle body 201. For the embodiment in which the device is a watch, the assembly method is to pass the ear through the watch strap and set two resilient components 300 at both ends of the ear for fixing. It should be noted that a single resilient component 300 can also achieve a rebound effect, and the number of resilient components 300 is not limited to the two resilient components 300 provided in the embodiment of the present application.

[0044] The limiting structure 102 is provided in the body 100 and can be assembled in various ways. Hereinafter, one example is used in which the limiting structure 102 is integrally formed with the body 100. The limiting structure and the body 100 are injection molded so that the limiting structure forms a contoured structure of the resilient member 300 to achieve position limiting. The integrally formed assembly method is more accurate.

[0045] Of course, the main body 100 with the limiting structure can also be as follows Figure 3 As shown, while retaining the existing main body structure, a built-in limiting structure, such as a head 102, is incorporated. Head 102 is mounted on the inner side of the watch case lug and has an arcuate surface that matches the outer shape of the watch case. Head 102 is enclosed within the main body 100. A limiting structure is formed within the head for limiting the rebound component 300, restricting its swinging motion and causing tension within the rebound component 300, generating a rebound force F1.

[0046] It should be noted that the limiting structure in the main body 100 can be the head particle provided above, or other independent limiting components, which is not limited here.

[0047] Among them, such as Figure 3 and Figure 4 As shown, the limiting structure 102 is made of a hard material. To ensure that the limiting structure restricts the resilient component, the limiting structure 102 is built into the body 100 and has a third through-hole 103 corresponding to the first through-hole 101. The link 203 passes through this third through-hole 103. In other words, the limiting structure 102 is similar to a convex structure, comprising a first portion and a second portion connected by a connecting portion, allowing the link 203 to pass through the first and second portions and secure the resilient component 300 and the buckle body. The connecting portion ensures the connection between the first and second portions, facilitating handling during injection molding.

[0048] During actual use, there will be wear between components. For example, the limiting structure 102 may become loose due to long-term use. Therefore, a protrusion is provided on the surface of the limiting structure 102, and a groove corresponding to the protrusion is provided inside the main body 100, thereby extending the service life of the buckle.

[0049] The material of the limiting structure can be hard plastic, steel mold, etc., which is not limited here.

[0050] The following implementation method is provided for the connection relationship between the rebound component, the limiting structure and the buckle body: one end of the rebound component 300 is embedded in the limiting structure of the body 100, and the other end is embedded in the buckle body 201, such as Figure 5 As shown, Figure 5The present invention provides a partial schematic diagram of the connection relationship of a fastener device. After the link 203 passes through the first through-hole 101 on the main body and the second through-hole 2021 on the buckle tongue 202, it penetrates the resilient component 300 and is fixed to the limiting structure of the main body 100 and the buckle body 201. One end of the resilient component 300 is set in the limiting structure of the main body 100, and the other end is embedded in the buckle body 201. The complete assembly ensures that when the buckle body 201 is flipped by a force, it rebounds through the resilient component 300, allowing the buckle body 201 to return to its original position. Compared with the prior art, there is no need to hollow out the interior of the link 203 for assembly. Only simple component assembly is required, which has low process requirements and effectively reduces costs.

[0051] There are various ways to connect the resilient component 300 to the buckle body 201. Here, for example, a slot is provided on the buckle body 201, and the other end of the resilient component 300 is embedded in the slot. In other words, one end of the resilient component 300 is embedded in the retaining structure, while the other end is embedded in the slot. The resilient component is then sheathed over the link 203, allowing the link 203 to be assembled with the buckle body 201 and the main body 100, respectively, via the resilient component 300.

[0052] Among them, there are various ways to embed the rebound component 300 into the buckle body 201. It can be achieved by setting a groove on the buckle body 201 as mentioned above, or by directly pressing on the buckle body 201 to achieve embedding, or other methods, which are not limited here.

[0053] In a watch, the resilient component 300 is specifically a torsion spring, also known as a torsion spring, which is a type of coil spring. The ends of a torsion spring are fixed to other components. When the other components rotate around the spring's center, the spring pulls them back to their original position, generating torque or rotational force. The two torsion springs are respectively mounted on a link, or spring lug, to achieve assembly.

[0054] In the assembly described above, it can be seen that both the resilient component 300 and the link 202 are built into the watchband. A retaining structure is also required within the watchband, so the thickness of the end where the watchband connects to the buckle 200 is no less than 5 mm. To ensure the watch does not increase in weight, the watchband is perforated to achieve symmetry on both sides of the dial, reducing weight while achieving an aesthetically pleasing effect.

[0055] The embodiment of the present application also specifically provides a method for installing a fastener, such as Figure 6As shown, it includes: S601. Fixing the limiting structure in the body. The limiting structure is built into the body of the buckle to achieve limiting fixation. In the method of installing the buckle, the limiting structure is first fixed in the body. Taking a watch as an example, the limiting structure can be a head particle, and the head particle is built into the watch. S602. After the link of the buckle passes through the body, the rebound components are placed from both ends of the link to the limiting structure of the body. After the link of the buckle passes through the body, the rebound components are placed on the limiting structure of the body at both ends of the link passing through the body, so that the link, the rebound component and the body are fixed. S603. Fix the other end of the rebound component to the buckle. After one end of the above-mentioned rebound component is fixed to the body, the other end is fixed to the buckle. In one example, the rebound component and the buckle are fixed by screws.

[0056] In one possible embodiment, the link member can pass through the body because: the body is provided with a first through-hole; the tongue is provided with a second through-hole; the link member passes through the first and second through-holes to connect the body to the clip; one end of the resilient component is positioned within the retaining structure and connected to the link member, while the other end is embedded in the clip body. In other words, the link member in the clip passes through the first through-hole provided in the body and the second through-hole provided in the tongue, and after passing through, is secured to the body and the clip body of the clip via the resilient component.

[0057] In one possible embodiment, the limiting structure is made of a hard material. The limiting structure is provided to better limit the installation of the resilient component. The resilient component itself can deform, and to ensure that the deformation is not buffered by other components, the limiting structure is provided with a hard material that does not buffer the resilient component.

[0058] The above-mentioned assembly method is only a preferred embodiment and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
