Description

Technical Field

[0001] This application relates to the technical field of watches, and more particularly to a rotating connection structure, a smart host, and a smartwatch. Background Technology

[0002] In the current field of smartwatch and precision timekeeping instrument design, the watch hinge assembly, as a key component connecting the strap and case and enabling wearing adjustment and fixation functions, directly affects the overall aesthetics, wearing comfort, and the rationality of the internal mechanical structure layout of the watch. Traditional watch hinge assemblies often adopt a relatively large design to ensure sufficient structural strength and ease of operation, but this design inevitably increases the size of the component and occupies valuable internal space resources of the watch movement.

[0003] With consumers increasingly demanding thinner, lighter, and more stylish smartwatches, and with the continuous improvement of smartwatch functionality integration, miniaturizing the hinge assembly while maintaining its functionality and durability has become a pressing technical challenge. Traditional wide hinge designs can no longer meet the demands of modern smartwatches for compact structures, especially given the trend towards ultra-thinness and complex functional integration. The size and length of the hinge assembly have become key factors limiting the optimization of the overall watch design. Utility Model Content

[0004] The purpose of this application is to provide a rotating connection structure, a smart host, and a smartwatch. By integrally molding the damping part onto the connector to form a structural component, the number of springs set inside the traditional rotating shaft is reduced, the size and volume of the entire structure are reduced, and the assembly and process flow are simplified, effectively reducing production costs.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, a rotating connection structure is provided, including: a first bracket and a connector. The first bracket is provided with a protruding plate, and a rotating part is formed by extending one side of the protruding plate. The connector is integrally formed with a damping part that rotates with the rotating part. The damping part and the rotating part can rotate relative to each other, and a damping force is formed by the moving friction between them.

[0007] Furthermore, one end of the damping part is integrally formed with the connector, and an opening is formed between the other end and the connector.

[0008] Furthermore, a connecting portion is provided at the opening, which connects the damping portion and the connecting member respectively, so that the damping portion forms a closed loop structure on the connecting member.

[0009] Furthermore, the connector is provided with a connection hole for connecting to the smart host.

[0010] Furthermore, two convex plates are provided, which are spaced apart on the first bracket, and the axes of the rotating parts extending from the two convex plates are collinear. Two connecting members are provided, and the damping part is correspondingly sleeved on the rotating part.

[0011] Furthermore, the distance between the end faces of the two rotating parts is A, where 14.6mm≤A≤16.3mm.

[0012] Furthermore, after the damping part is installed on the rotating part, it forms a shoulder on the first bracket, and the diameter of the shoulder is B, where 3.3mm≤B≤5.1mm.

[0013] Furthermore, the damping part is a rolled sheet.

[0014] Furthermore, it also includes a second bracket, which is rotatably mounted on the side of the first bracket opposite to the convex plate via a rotating component.

[0015] On the other hand, a smart host is also provided, including: a host body and a rotating connection structure as described above, wherein the host body is connected to the connector.

[0016] On the other hand, there is also a smartwatch, including a support plate, a watch strap, and a smart host as described above, wherein the first bracket is rotatably connected to the support plate, and the watch strap is connected to the support plate.

[0017] Furthermore, the support plate is rotatably connected to the second bracket.

[0018] The beneficial effects of this application are as follows: The structure includes a first support with a protruding plate on it. A rotating part extending from one side of the protruding plate forms a precise fit with an integrally formed damping part on the connector. This integrated damping part not only eliminates the traditional spring-loaded side-shaft structure, but also generates a stable and controllable moving friction force when the connector rotates relative to the first support through precise mating surfaces and the selection of specific materials. This ensures smooth rotation while effectively preventing excessively fast or violent rotation, thereby improving the accuracy and comfort of user operation.

[0019] Most importantly, this integrated design significantly reduces the shoulder size, lug space, and axial length of the entire rotating connection structure, providing more ample layout space for other key components inside the smartwatch and greatly promoting the thinner and lighter design and functional integration of the product. At the same time, this design also simplifies the assembly process, reduces reliance on precision assembly tools, effectively shortens the production cycle, and significantly reduces production costs.

[0020] Furthermore, by reducing the number of connection points between components, the stability of this rotating connection structure is significantly enhanced, greatly reducing the probability of failure due to loose connections, and thus improving overall reliability and durability. Users can enjoy a more stable and smooth operating experience, which undoubtedly adds more market competitiveness to smartwatches and other electronic products. In summary, this innovative rotating connection structure not only achieves a compact and lightweight structure but also significantly improves product reliability and user experience, representing a major technological breakthrough in the field of smartwatches and other electronic products.

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical 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 based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] like Figures 1-4 As shown, this embodiment provides a rotating connection structure, including: a first bracket 1 and a connector 2. The first bracket 1 is provided with a protruding plate 101, and a rotating part 102 extends from one side of the protruding plate 101. The connector 2 is integrally formed with a damping part 3 that rotates with the rotating part 102. The damping part 3 and the rotating part 102 can rotate relative to each other, and a damping force is formed by the moving friction between the two.

[0032] Based on the above solution, this structure cleverly integrates the design of the first support 1 and the convex plate 101. The precision rotating part 102 extending from one side of the convex plate 101 perfectly matches the integrally formed damping part 3 on the connector 2. This integrated design not only eliminates the complex structures of traditional spring-loaded side shafts, but also significantly reduces the vertical dimensions, lug space, and axial length of the structure, freeing up valuable layout space for other key components inside the smartwatch and driving product design towards thinner, lighter, and more functional designs. Simultaneously, the damping part 3 and the rotating part 102, through their precise mating surfaces and the active friction generated by specific material properties, form a stable and controllable damping force, ensuring smooth rotation and precise operation. This avoids the inconvenience caused by excessively fast rotation and improves user comfort and satisfaction. Furthermore, the integral molding technology not only simplifies the assembly process and reduces reliance on precision assembly tools, effectively shortening the production cycle, but also significantly reduces production costs. More importantly, reducing the number of connection points between components significantly enhances the structural stability, reduces the risk of failure, and further improves the overall reliability and durability of the rotating connection structure.

[0033] Furthermore, one end of the damping part 3 is integrally formed with the connecting member 2, and the other end has an opening 7 between it and the connecting member 2. This design breaks the limitations of the traditional closed structure and forms an open structure design. This open structure design brings multiple advantages: First, the presence of the opening 7 allows the damping part 3 to have a certain elastic adjustment space during rotation, better adapting to the needs of different rotation speeds and forces, further improving the smoothness of rotation and the user's operating experience. Second, compared with the closed structure, the open structure is more streamlined in terms of material usage, which helps to reduce the overall weight, while optimizing the utilization of internal space, providing more design possibilities for small electronic devices such as smartwatches. In addition, the design of the opening 7 simplifies the manufacturing process of the damping part 3, reduces material waste and processing difficulty, and helps to reduce production costs and improve production efficiency.

[0034] As an optional specific implementation scheme, in the design of the rotating connection structure, in view of the problem that the opening 7 may increase under stress, thereby causing the damping part 3 to detach from the rotating part 102, an innovative and effective specific implementation scheme is to cleverly set the connecting part 8 at the opening 7. This design not only ensures the stable connection between the damping part 3 and the connecting part 2, but also solves the problem of structural failure that may be caused by the increase of the opening 7 under stress.

[0035] Specifically, such as Figure 5As shown, the connecting part 8 in this embodiment plays a crucial role in fixing and supporting the structure. One end is firmly connected to the damping part 3, and the other end is tightly integrated with the connecting member 2, thus physically forming a closed-loop structure. This closed-loop design effectively limits the expansion tendency of the opening 7 under stress, ensuring a tight fit and stable connection between the damping part 3 and the connecting member 2. The closed-loop design significantly enhances the overall stability of the rotating connection structure, especially under high stress, effectively preventing the damping part 3 from separating from the connecting member 2, ensuring the integrity and functionality of the structure. By limiting the expansion of the opening 7, the connecting part 8 reduces wear and deformation caused by long-term stress, thereby improving the durability of the rotating connection structure and extending the product's service life. The stable connection ensures that the damping part 3 can continuously provide uniform damping force during rotation, avoiding rotational jamming or obstruction caused by structural instability, improving the smoothness of rotation and the user's operating experience.

[0036] It is worth mentioning that the connecting part 8 and the damping part 3 are integrally molded parts, while the connecting part 8 and the connecting piece 2 are detachable structures to improve the adaptability of assembly.

[0037] In some embodiments, to better integrate the rotating connection structure into smart devices such as smartwatches, the connector 2 is specially provided with a connection hole 201 for connecting to the smart host. This design not only allows the rotating connection structure to be securely installed in the corresponding position of the smart host, but also ensures the functional integrity of the entire system and the stability of signal transmission. Moreover, the connection hole 201 is usually carefully laid out and sized to ensure a perfect match with the corresponding interface on the smart host.

[0038] Preferably, to further enhance the stability and load-bearing capacity of the rotating connection structure, two protruding plates 101 are specially provided on the first support 1, and these two protruding plates 101 are arranged at intervals. This interval arrangement not only helps to disperse stress and improve the overall strength of the structure, but also provides greater flexibility and space for the arrangement of the rotating part 102. Importantly, the axes of the rotating parts 102 extending from the two protruding plates 101 are designed to be collinear, which means that the two rotating parts 102 will remain synchronous and consistent during rotation, thereby ensuring the smoothness and reliability of the connector 2 during rotation. This collinear design also helps to reduce friction and wear caused by asynchronous rotation, extending the service life of the rotating connection structure. Corresponding to the two protruding plates 101, two connectors 2 are also provided. Each connector 2 is equipped with a damping part 3 that precisely matches the rotating part 102. These damping parts 3 are correspondingly sleeved on the rotating part 102 to ensure smoothness and stability during rotation. By cooperating with the two connectors 2 and the rotating parts 102 on the two protruding plates 101, the rotating connection structure can distribute stress and bear load more evenly, thereby improving the overall load-bearing capacity and durability.

[0039] Furthermore, this design of double convex plates 101 and double connectors 2 provides more functionalities and design possibilities for smart devices such as smartwatches. For example, it provides more stable support for screen rotation. At the same time, due to the collinear arrangement of the axes of the rotating parts 102, this design also helps to maintain the overall aesthetics and harmony of devices such as smartwatches.

[0040] Generally, traditional hinge assemblies often have a long axial length, typically exceeding 16.3mm, due to the need for complex structures such as springs and side shafts. These additional components not only increase the overall size and weight but may also limit the internal layout and space utilization of smart devices like smartwatches. However, in this solution, through an innovative design approach, the integrated design of connector 2 and damping part 3, along with the connection of rotating part 102, successfully avoids the use of springs and side shafts in traditional hinge assemblies, thereby significantly shortening the axial length. Specifically, the distance A between the end faces of the two rotating parts 102, i.e., the axial length, is controlled within a more compact range, between 14.6mm and 16.3mm. This optimization makes the rotating connection structure more compact and lightweight.

[0041] Simultaneously, after the damping part 3 is installed on the rotating part 102, it forms a shoulder part 6 on the first bracket 1. The diameter of the shoulder part 6 is B, where 3.3mm ≤ B ≤ 5.1mm. The shoulder part 6, as a key component in the combination of the damping part 3, the rotating part 102, and the first bracket 1, has a significant impact on the overall performance and appearance of the rotating connection structure due to its size and shape. In traditional pivot assemblies, due to the presence of springs and side shafts, the diameter of the shoulder part 6 is often large, typically above 5.1mm. These additional components not only increase the volume of the shoulder part 6 but may also adversely affect the overall aesthetics and harmony of smart devices such as smartwatches.

[0042] This solution, through innovative design, successfully avoids the use of springs and side shafts in traditional hinge assemblies, thereby significantly reducing the diameter of the shoulder section 6. Specifically, the diameter B of the shoulder section 6 is controlled within a more compact range, between 3.3mm and 5.1mm. However, in reality, by avoiding springs and side shafts, this solution can achieve an even smaller diameter, close to 3.3mm. This optimization not only makes the rotating connection structure more compact and refined but also provides more design flexibility and space utilization possibilities for smartwatches and other smart devices. The reduction in the diameter of the shoulder section 6 not only helps improve the overall aesthetics and harmony of the product but may also have a positive impact on the wearing comfort and user experience of smartwatches and other smart devices. A smaller shoulder section 6 diameter means less space occupation and a more comfortable wearing experience, which is especially important for smartwatches and other smart devices that pursue an ultra-thin and comfortable experience.

[0043] The damping part 3 is a rolled-up strip. This rolled-up strip design allows the damping part 3 to maintain sufficient damping effect while occupying less space, which is especially important for space-constrained smart devices such as smartwatches, contributing to a more compact and lightweight design. Furthermore, the rolled-up strip is made of high-quality, wear-resistant, and corrosion-resistant materials to ensure it maintains good performance and appearance during long-term use. This durable design helps extend the lifespan of smartwatches and other smart devices and reduces maintenance costs.

[0044] Besides the roll-up design, the damping section 3 can also use silicone rings or rubber rings as alternatives. These materials also have unique advantages and characteristics in rotating connection structures. Silicone rings have good elasticity, providing stable damping during rotation while reducing wear and noise. They also maintain stable performance over a wide temperature range, making them suitable for smartwatches and other smart devices in various extreme environments. Furthermore, silicone has good corrosion resistance to many chemicals, protecting the rotating connection structure from corrosion and damage. Silicone material is harmless to the human body and suitable for smartwatches and other smart devices that come into direct contact with the skin, ensuring user health and safety.

[0045] The rubber ring has a high damping coefficient, providing a significant damping effect that helps slow down rotational speed and improves the stability of the rotating connection. The rubber material also exhibits good wear resistance, maintaining the integrity and performance of the damping section 3 during long-term use. Furthermore, it possesses certain shock absorption properties, absorbing shocks and vibrations during rotation and enhancing the comfort and stability of smart devices such as smartwatches.

[0046] Generally, it also includes a second bracket 4, which is rotatably mounted on the side of the first bracket 1 opposite to the protruding plate 101, i.e., the lower side of the first bracket 1, via a rotating component 5. The second bracket 4, as a supporting part of the rotating connection structure, enhances the stability of the overall structure. Through its rotatable connection with the first bracket 1, it provides stable support in all directions, preventing deformation or damage to the rotating connection structure under stress. The presence of the second bracket 4 provides more functional expansion space for smart devices such as smartwatches. For example, it can serve as a fixing part of the watch strap, forming a complete wearing structure together with the first bracket 1.

[0047] On the other hand, a smart host is also provided, including: a host body and a rotating connection structure as described above, wherein the host body is connected to the connector 2.

[0048] On the other hand, there is also a smartwatch, including a support plate, a watch strap, and a smart main unit as described above, wherein the first bracket 1 is rotatably connected to the support plate. The watch strap is connected to the support plate. The rotatable connection between the first bracket 1 and the support plate can be understood as the rotatable connection between the second bracket 4 and the support plate. The first bracket 1 and the second bracket 4 are rotatably connected, allowing the first bracket 1 to rotate relative to the support plate in at least two directions. For example, the main unit can be rotated from a horizontal to a vertical position by first flipping the second bracket 4 relative to the support plate, and then rotated horizontally by rotating the first bracket 1 relative to the second bracket 4, adapting to different usage scenarios, such as taking photos.
