Description

Technical Field

[0001] This application relates to the field of smart wearable device technology, and in particular to a rotating connection structure, a smart host, and a smart wearable device. Background Technology

[0002] With the development of technology, wearable electronic products (such as smartwatches and smart bracelets) are becoming increasingly popular among consumers. Wearable electronic products are often small and portable, and can meet consumers' functional needs to the greatest extent, such as taking pictures, making video calls, and scanning QR codes. To achieve these functions, wearable electronic products need to be equipped with cameras.

[0003] Related technologies utilize various methods to enable the camera on the main unit to capture more shooting angles. These include adding a support plate and a hinge, allowing the main unit to rotate relative to the support plate via the hinge, thus adjusting the shooting angle. To ensure the main unit remains at the desired angle after rotation, a spring is typically fitted around the hinge to provide damping and maintain the current angle.

[0004] However, in order to ensure that the spring has sufficient elasticity to guarantee the damping effect, the diameter of the spring is designed to be relatively large, resulting in a larger spring volume. This leads to an increase in the overall thickness of wearable electronic products, which does not conform to the design of wearable electronic products to be thin, light and small.

[0047] Thirdly, this application discloses a smart wearable device, which includes a wearable component and a smart host as described in the second aspect above, wherein the wearable component is connected to the support bracket.

[0048] Compared with the prior art, the beneficial effects of this application are as follows:

[0049] The rotating connection structure, smart host, and smart wearable device provided in this application embodiment allow the host body to maintain its current angular position after rotating relative to the support bracket using the damping effect generated by the elastic component. By including a first elastic component and a second elastic component, the number of elastic components is increased, thereby increasing the overall elastic force of the elastic component and improving its damping effect, so that the host body can be stably maintained at the current angular position, thus allowing for an appropriate reduction in the diameter of the elastic component. Furthermore, considering the characteristics of the rotating connection structure itself, this application also arranges the first and second elastic components along the length direction of the rotating connection structure. By utilizing the already ample space of the rotating connection structure to accommodate the first and second elastic components, the size of the rotating connection structure in the width direction can be reduced without increasing its length, or even by reducing its length, thereby achieving a miniaturized design of the rotating connection structure.

[0050] As can be seen, the rotating connection structure, smart host, and smart wearable device provided in this application embodiment can increase the damping effect of the elastic component so that the host body can be stably maintained at the current angle, while realizing the miniaturization design of the rotating connection structure, which is in line with the miniaturization design of smart wearable devices.

Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments. That is, the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0076] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this application.

[0077] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first elastic component may be referred to as a second elastic component, and similarly, a second elastic component may be referred to as a first elastic component. Both the first elastic component and the second elastic component are elastic components, but they are not the same elastic component.

[0078] 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, unless otherwise stated, "a plurality of" means two or more.

[0079] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection 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.

[0080] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0081] In addition, the term "and / or" as used in this specification includes any and all combinations of the related listed items. For example, A and / or B can mean: A alone, A and B together, or B alone. That is, the term "and / or" as used in this specification includes any and all combinations of the related listed items.

[0082] Smart wearable electronic products (such as smartwatches and smart bracelets) are becoming increasingly popular among consumers, with smartwatches receiving particular attention. Compared to other wearable electronic products, smartwatches are not only small and portable, but also maximize the fulfillment of consumers' functional needs, such as making calls, voice communication, and video calls. Achieving these functions requires the wearable electronic product to be equipped with a camera.

[0083] However, the cameras of most smartwatches on the market are typically positioned upwards, facing the same direction as the watch's display. Therefore, when using the camera for shooting or video calls, users usually need to rotate their arm or wrist to adjust the camera's angle because the main unit cannot rotate. Based on this, rotating smartwatches have emerged to better realize the multi-functionality of smartwatches.

[0084] To facilitate the rotatable design of the main unit, a support plate is usually added, allowing the main unit to rotate relative to the support plate. A rotation axis is also added, so that after the main unit rotates to an angle relative to the support plate, it can also rotate relative to itself through the rotation axis, thereby achieving the effect of adjusting more shooting angles.

[0085] In order for the host to remain at the current angle after rotating to the required angle via the spin shaft, a spring is usually fitted around the outer circumference of the spin shaft. The damping effect of the spring helps it maintain the current angle.

[0086] However, in order to ensure that the spring has sufficient elasticity to guarantee the damping effect, the diameter of the spring cannot be designed too small and is usually designed to be relatively large. Moreover, the spring is sleeved on the outer circumference of the rotation shaft. In order to ensure the structural reliability of the rotation shaft, the diameter of the rotation shaft is generally not designed too small and is also designed to be relatively large. This results in the spring being designed to be relatively large as well, which leads to a larger spring volume. Consequently, the overall thickness of the smartwatch increases, which does not conform to the miniaturization design of smartwatches.

[0087] Therefore, how to improve the damping effect of the spring surrounding the rotation axis while achieving miniaturization of smartwatches, so that the main unit can stably maintain its current angle position, remains a technical challenge that urgently needs to be solved in the field of smartwatch technology.

[0088] In view of this, this application provides a rotating connection structure, a smart host, and a smart wearable device that can achieve a miniaturized design while ensuring the damping effect of the elastic component so that the host body can be stably maintained at the current angle.

[0089] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0090] Please see Figure 1 , Figure 1 The illustrative diagram illustrates the structure of a smartwatch as a smart wearable device provided in this application embodiment, but does not limit the smart wearable device of this application to only being a smartwatch. In other implementations of this application, the smart wearable device may also be a smart bracelet, etc., and this application does not specifically limit it in this regard.

[0091] like Figure 1 As shown, the smart wearable device 1000 provided in this application embodiment includes a smart host 100 and a wearable component 200. The wearable component 200 is connected to the smart host 100, so that the smart host 100 can be worn on the user's wrist, making it convenient for the user to wear the smart wearable device 1000.

[0092] For example, the wearable component 200 may be a watch strap that is rotatably connected to the smart host 100 and is primarily for use by the user on their wrist.

[0093] exist Figure 1 In the illustrated embodiment, the aforementioned wearable component 200 may be one or two. When there are two wearable components 200, the two wearable components 200 may be a first wearable component 200a and a second wearable component 200b, wherein the first wearable component 200a is rotatably connected to one end of the smart host 100, and the second wearable component 200b is rotatably connected to the other end of the smart host 100, and the second wearable component 200b and the first wearable component 200a are detachably connected to facilitate wearing the smart host 100 on the user's wrist and facilitating the removal of the smart host 100 from the user's wrist.

[0094] Please see Figure 2 , Figure 2 An exemplary schematic diagram illustrates the structure of the smart host body stacked on a support bracket according to an embodiment of this application. Figure 3 An exemplary schematic diagram illustrates the structure of the smart host provided in this application embodiment, where the host body is rotated at a certain angle relative to the support bracket. Figure 4 An exemplary schematic diagram illustrates the structure of the smart host provided in this application, where the host body rotates at a certain angle relative to the supporting bracket. Figure 5An exemplary schematic diagram illustrates the separate structure of the support bracket, host body, and rotating connection structure of the smart host provided in this application embodiment.

[0095] like Figures 1 to 5 As shown, the smart host 100 provided in this application embodiment includes a support bracket 1, a host body 2, and a rotating connection structure 3. The support bracket 1 is connected to the wearable component 200, and the rotating connection structure 3 is connected to both the support bracket 1 and the host body 2. The host body 2 can be flipped and / or rotated relative to the support bracket 1 under the drive of the rotating connection structure 3, so that the user can adjust the angle according to their own needs, which facilitates the use of functions such as selfies, foreground and background shooting, and QR code payment, providing convenience and ease of use for the user.

[0096] In this application, the host unit 2 can be used as the host of a smart wearable device, such as a smartwatch. That is, the host unit 2 can perform functions such as making calls, sending and receiving messages, taking photos, video calls, scanning QR codes, mobile payments, viewing environmental information, and viewing health information. Therefore, in this embodiment, the host unit 2 may include a motherboard (not shown), a camera, a display screen, a battery, a speaker, a microphone, a SIM card slot assembly, a communication module, and sensors that perform various functions. These sensors may include a gravity sensor, an accelerometer, a distance sensor, a heart rate sensor, a barometric pressure sensor, an ultraviolet detector, etc. Furthermore, the host unit 2 also includes components for identity verification, such as a fingerprint recognition module and a facial recognition module.

[0097] The rotating connection structure 3 provided in this application embodiment has a length direction f1, a width direction f2, and a thickness direction f3. The width direction f2 can be understood as the direction from one end of the support bracket 1 used to connect with the wearable component to the other end of the support bracket 1 used to connect with the wearable component. The thickness direction f3 can be understood as the direction from the support bracket 1 to the main body 2 when the main body 2 is stacked on the support bracket 1. The length direction f1 can be understood as the direction perpendicular to the width direction f2 and the thickness direction f3.

[0098] like Figure 5 and Figure 6 As shown, the rotating connection structure 3 provided in this embodiment includes a connector 31 and a rotating member 32. The connector 31 is connected to the support bracket 1, and the rotating member 32 is connected to the main body 2. The rotating member 32 is rotatably connected to the connector 31 so that the main body 2 can rotate relative to the support bracket 1. This allows the user to adjust the angle according to their needs, facilitating the use of functions such as selfies, foreground and background shooting, and QR code payment, providing convenience and ease of use for the user.

[0099] In some embodiments, the rotating connection structure 3 further includes a first shaft 33, which is connected to the connector 31 and the rotating member 32 respectively, and the axis of the first shaft 33 extends along the thickness direction f3 of the rotating connection structure 3.

[0100] In one example, the first shaft 33 and the rotating member 32 are fixedly connected, wherein the connection between the first shaft 33 and the rotating member 32 is non-detachable, the connection between the first shaft 33 and the rotating member 32 is detachable, and the first shaft 33 can rotate relative to the connecting member 31 to drive the rotating member 32 to rotate relative to the connecting member 31, thereby driving the main body 2 connected to the rotating member 32 to rotate, thus realizing the rotation design of the main body 2 relative to the support bracket 1.

[0101] Understandably, in actual use, the user can hold the main body 2 and make it rotate relative to the support bracket 1. During this process, the rotating part 32 and the first shaft 33 can rotate with the main body 2 relative to the connecting part 31.

[0102] The first shaft 33 rotates relative to the connecting member 31 within an angle range of 0° to 360°, for example, as Figure 4 As shown, the first shaft rotates 90° relative to the connector.

[0103] In another exemplary configuration, the first shaft 33 and the connector 31 are fixedly connected, wherein the connection between the first shaft 33 and the connector 31 is non-detachable, the connection between the first shaft 33 and the connector 31 is detachable, and the rotating member 32 can rotate relative to the first shaft 33 to realize the rotation of the rotating member 32 relative to the connector 31, thereby driving the main body 2 connected to the rotating member 32 to rotate, thus realizing the rotation design of the main body 2 relative to the support bracket 1.

[0104] Understandably, in actual use, the user can hold the main body 2 and make it rotate relative to the support bracket 1. During this process, the rotating part 32 can rotate with the main body 2 relative to the first axis 33.

[0105] The rotating member 32 rotates relative to the first shaft 33 within an angle range of 0° to 360°, for example, as Figure 4 As shown, the rotating component rotates 90° relative to the first shaft.

[0106] In some embodiments, combined with Figures 6 to 8As shown, the rotating member 32 is in contact with the connecting member 31. The rotating connection structure 3 also includes a clamping member 34 and an elastic component 35. The clamping member 34 is connected to the first shaft 33 or the rotating member 32, and the clamping member 34 is located on the side of the rotating member 32 facing away from the connecting member 31. The elastic component 35 includes a first elastic component 35a and a second elastic component 35b arranged along the length direction f1 of the rotating connection structure 3. The first elastic component 35a and the second elastic component 35b are both abutted between the rotating member 32 and the clamping member 34, and the first elastic component 35a and the second elastic component 35b are both used to provide a damping force to keep the rotating member 32 in its state after rotating relative to the connecting member 31.

[0107] It should be noted that, since the first elastic component 35a and the second elastic component 35b are in a pre-tightened state after assembly, when the rotating component 32 rotates relative to the connecting component 31, the first elastic component 35a and the second elastic component 35b will press against the rotating component 32, so that when the rotating component 32 rotates relative to the connecting component 31, friction is generated between the rotating component 32 and the connecting component 31, which has a damping effect. This allows the rotating component 32 to remain in its current state after rotating relative to the connecting component 31, so that the main body 2 can remain in its current angle position after rotating relative to the support bracket 1, which is convenient for the user to operate the main body 2.

[0108] Optionally, both the first elastic component 35a and the second elastic component 35b can be springs or elastic ring structures made of elastic materials, wherein the elastic ring structure made of elastic materials can be a silicone ring or a rubber ring, etc.

[0109] In the above scheme, by including a first elastic component 35a and a second elastic component 35b in the elastic component 35, the number of elastic components is increased, thereby increasing the overall elastic force of the elastic component 35 and improving the damping effect of the elastic component 35, so that the main body 2 can be stably maintained at the current angle position, thereby appropriately reducing the diameter of the elastic component; at the same time, combined with the characteristics of the rotating connection structure 3 itself, this application also arranges the first elastic component 35a and the second elastic component 35b along the length direction f1 of the rotating connection structure 3, making use of the relatively ample space of the rotating connection structure 3 to arrange the first elastic component 35a and the second elastic component 35b. The elastic component 35b can reduce the size of the rotating connection structure 3 in the width direction f2 without increasing its length direction f1, or even by reducing its length direction f1. For example, the size of the rotating connection structure 3 in the width direction f2 can be reduced from the original range of 4.8mm-6.9mm to the range of 3.8mm-4.7mm. For example, the size of the rotating connection structure 3 in the width direction f2 can be reduced from the original 6.5mm to 4.3mm, thereby achieving a miniaturized design of the rotating connection structure 3.

[0110] As can be seen, the rotating connection structure 3 provided in this application embodiment can increase the damping effect of the elastic component 35 so that the host body 2 can be stably maintained at the current angle, while realizing the miniaturization design of the rotating connection structure 3, which is in line with the miniaturization design of smart wearable devices.

[0111] In some embodiments, such as Figure 8 As shown, the first elastic component 35a and the second elastic component 35b are located on both sides of the first shaft 33 in the length direction f1, respectively, to avoid the first elastic component 35a and the second elastic component 35b acting on a certain position of the rotating component 32 in a concentrated manner. This allows the rotating component 32 to be subjected to balanced forces, which is conducive to the rotating component 32 rotating smoothly relative to the connecting component 31, thereby facilitating the smooth rotation of the main body relative to the support bracket.

[0112] Optionally, the first elastic component 35a and the second elastic component 35b are symmetrically arranged about the first shaft 33, which can make the force on the rotating component 32 more uniform and balanced, thus making it more conducive to the rotating component 32 to rotate smoothly relative to the connecting component 31, and further making it more conducive to the main body 2 to rotate smoothly relative to the support bracket 1.

[0113] In some embodiments, the rotating connection structure 3 further includes a support column (not shown) connected between the clamping member 34 and the rotating member 32, such that the clamping member 34 can be connected to the rotating member 32 through the support column, and such that there is a gap between the clamping member 34 and the rotating member 32, allowing the first elastic member 35a and the second elastic member 35b to abut between the clamping member 34 and the rotating member 32.

[0114] In some embodiments, such as Figure 8 and Figure 9 As shown, the rotating member 32 is provided with a first shaft hole 321 that extends along the thickness direction f3. The first shaft body 33 passes through the first shaft hole 321. The clamping member 34 is connected to the first shaft body 33. That is, a part of the first shaft body 33 is located outside the first shaft hole 321. Thus, the clamping member 34 can be connected to the part of the first shaft body 33 located outside the first shaft hole 321. The clamping member 34 is connected to the rotating member 32 through the first shaft body 33, and there is a gap between the clamping member 34 and the rotating member 32, so that the first elastic member 35a and the second elastic member 35b can abut between the clamping member 34 and the rotating member 32.

[0115] This configuration allows the existing structure (i.e., the first shaft 33) to be used to install and fix the clamping member 34 without the need for additional support structures. This reduces the number of parts in the rotating connection structure 3, simplifies its structure, and facilitates the miniaturization of the rotating connection structure 3.

[0116] Optionally, the clamping member 34 and the first shaft 33 can be fixed by riveting, which is a simple, stable and reliable fixing method.

[0117] Understandably, when the connection between the first shaft 33 and the rotating member 32 is a fixed connection, the first shaft 33 can be a flat shaft (e.g., a flat square shaft), and the first shaft hole 321 can be a flat hole (e.g., a flat square hole) that matches the shape of the first shaft 33, so that the rotating member 32 cannot rotate relative to the first shaft 33. When the main body 2 is rotated, the first shaft 33 can rotate together with the rotating member 32 along with the main body 2. However, when the connection between the first shaft 33 and the rotating member 32 is a rotatable connection, the first shaft 33 is a cylindrical shaft, and the first shaft hole 321 is a circular hole that matches the shape of the first shaft 33. The first shaft 33 is rotatably inserted into the first shaft hole 321, so that the rotating member 32 can rotate relative to the first shaft 33. When the main body 2 is rotated, the rotating member 32 can rotate together with the main body 2 relative to the first shaft 33.

[0118] In some embodiments, such as Figure 8 and Figure 9 As shown, the clamping member 34 and / or the rotating member 32 are provided with a first column 341. That is, only the clamping member 34 can be provided with a first column 341, only the rotating member 32 can be provided with a first column 341, or both the clamping member 34 and the rotating member 32 can be provided with a first column 341. The first elastic member 35a is sleeved on the outer periphery of the first column 341. In this way, the first column 341 can not only be used to position the first elastic member 35a, making it easier to abut the first elastic member 35a between the clamping member 34 and the rotating member 32, but also to guide the deformation of the first elastic member 35a.

[0119] Similarly, the clamping member 34 and / or the rotating member 32 are provided with a second column 342. That is, only the clamping member 34 can be provided with a second column 342, only the rotating member 32 can be provided with a second column 342, or both the clamping member 34 and the rotating member 32 can be provided with a second column 342. The second elastic member 35b is sleeved on the outer periphery of the second column 342. In this way, the second column 342 can not only be used to position the second elastic member 35b, making it easier to abut the second elastic member 35b between the clamping member 34 and the rotating member 32, but also to guide the deformation of the second elastic member 35b.

[0120] In some embodiments, combined with Figures 6 to 9As shown, one of the connecting member 31 and the rotating member 32 is provided with at least one protrusion 311, and the other of the connecting member 31 and the rotating member 32 is provided with multiple recesses 322. That is, when the connecting member 31 is provided with at least one protrusion 311, the rotating member 32 is provided with multiple recesses 322; and when the rotating member 32 is provided with at least one protrusion 311, the connecting member 31 is provided with multiple recesses 322. The multiple recesses 322 are arranged at intervals along the rotation direction of the rotating member 32, and when the rotating member 32 rotates relative to the connecting member 31 to a preset angle, the protrusion 311 is embedded in any one of the recesses 322. In this way, a blunt sensation of rotation can be generated when the rotating member 32 rotates to the preset angle. On the one hand, it is easier for the user to know the angle of rotation, and on the other hand, it can also improve the user's feel of rotation.

[0121] It is understandable that there is a known angle between each pair of adjacent recesses 322, which is also the preset angle mentioned above. Thus, when the rotating member 32 rotates relative to the connecting member 31 in the rotation direction through the main body 2, and the protrusion 311 exits from one recess 322 and enters another recess 322, the user can know the rotation angle of the main body 2 based on the known angle.

[0122] In addition, during the rotation of the rotating member 32 relative to the connecting member 31, the first elastic member 35a and the second elastic member 35b provide a force to push the rotating member 32 toward the connecting member 31. In addition to the damping force that keeps the rotating member 32 in its state after rotation relative to the connecting member 31, it also allows the protrusion 311 to enter the multiple recesses 322 in sequence. As a result, during the rotation of the rotating member 32 relative to the connecting member 31, a more obvious sense of jerking can be generated. Thus, during the rotation of the main body 2 relative to the connecting member 31, the main body 2 will also obtain a more obvious sense of jerking, that is, a stronger gear shift feel.

[0123] Specifically, during the rotation of the rotating member 32 relative to the connecting member 31, the protrusion 311 enters one of the recesses 322. At this time, the first elastic member 35a and the second elastic member 35b push the rotating member 32 toward the connecting member 31. After the rotating member 32 continues to rotate relative to the connecting member 31 at a certain angle, the protrusion 311 will exit from the recess 322. At this time, the rotating member 32 moves in the direction away from the connecting member 31, while compressing the first elastic member 35a and the second elastic member 35b. After the rotating member 32 continues to rotate relative to the connecting member 31 at a certain angle again, the protrusion 311 will enter another recess 322 adjacent to the above-mentioned recess 322. When the protrusion 311 enters the recess 322, a noticeable jerking sensation can be produced.

[0124] Optionally, the protrusions 311 include multiple protrusions, and the number of protrusions 311 is equal to the number of recesses 322. The multiple protrusions 311 are evenly distributed around the first shaft 33, and the multiple recesses 322 are evenly distributed around the first shaft 33. When the rotating member 32 rotates relative to the connecting member 31 to a preset angle, each protrusion 311 is embedded in a recess 322.

[0125] Therefore, during the rotation of the gear shift plate relative to the fixed shaft, multiple evenly distributed protrusions 311 simultaneously enter multiple recesses 322, or multiple evenly distributed protrusions 311 simultaneously exit from multiple recesses 322. This improves the gear shift feel and ensures that the gear shift plate is subjected to uniform force during rotation relative to the fixed shaft, thereby improving the stability of the gear shift plate movement.

[0126] For example, there can be two protrusions 311 and two recesses 322. The two protrusions 311 are symmetrically arranged about the center of the first shaft 33, and the two recesses 322 are symmetrically arranged about the center of the first shaft 33. This allows the two protrusions 311 to be engaged with the two recesses 322 respectively when the rotating member 32 rotates 0° or 180° relative to the connecting member 31. In this way, the rotation angle of the main body 2 relative to the support bracket 1 can be limited, so that rotational resistance is generated when the rotating member 32 rotates to a preset angle. For example, rotational resistance is generated when the rotating member 32 rotates to 0°, 90°, or 180°, so that the user can perceive the current rotation angle and know that the main body 2 has been rotated to the preset angle and that preset operations can be performed on the main body 2 at this time.

[0127] In some embodiments, such as Figure 10 and Figure 11 As shown, the rotating component 32 has two protrusions 323 on the surface facing away from the connecting component 31, which protrude along the thickness direction f3. The two protrusions 323 are spaced apart along the length direction f1. The elastic component 35 is located between the two protrusions 323. Each protrusion 323 is provided with a second shaft hole 324 that passes through along the length direction f1. The rotating connection structure 3 also includes two second shafts 36. Each second shaft 36 is rotatably inserted into a second shaft hole 324. The part of each second shaft 36 outside the second shaft hole 324 is used to be fixedly connected to the main body, so that when the second shaft 36 rotates relative to the second shaft hole 324, it can drive the main body to rotate relative to the support bracket.

[0128] That is, in actual use, the user can hold the main body 2 and make it rotate relative to the support bracket 1. The second shaft 36 can rotate with the main body 2 relative to the second shaft hole 324. In this process, it mainly rotates around the central axis of the second shaft 36. After the main body 2 is rotated at a certain angle relative to the support bracket 1, the user can also hold the main body 2 and make it rotate relative to the support bracket 1. The rotating part 32 and the first shaft 33 rotate with the main body 2 relative to the connecting part 31. Alternatively, the rotating part 32 rotates with the main body 2 relative to the first shaft 33 and rotates relative to the connecting part 31. In this process, it mainly rotates around the central axis of the first shaft 33.

[0129] As can be seen, by adopting the technical solution of this application, the host body 2 can both flip and rotate, thereby enabling the camera on the host body 2 to have more different shooting directions, making it easier for users to adjust the angle according to their own needs, and making it more convenient to use functions such as selfies, foreground and background shooting, and QR code payment, providing users with convenience and ease of use.

[0130] In some embodiments, the rotating connection structure 3 further includes two connecting parts 37. One connecting part 37 is connected to a second shaft 36, and two bosses 323 are located between the two connecting parts 37. Each connecting part 37 includes a first connecting portion 371 and a second connecting portion 372 connected together. The first connecting portion 371 is fixed to the second shaft 36, and the second connecting portion 372 is perpendicular to the first connecting portion 371. The second connecting portion 372 is provided with a first connecting hole 372a, which is used to connect with the main body 2. Specifically, the main body 2 is provided with a second connecting hole (not shown) corresponding to the position of the first connecting hole 372a. A threaded fastener passes through the first connecting hole 372a and the second connecting hole to fix the main body 2 onto the second connecting portion 372. The threaded fastener can be a bolt, screw, etc.

[0131] This configuration allows the main body 2 to be fixed to the connecting component 37 via a threaded connection, which is a simple, stable, and reliable fixing method.

[0132] In some embodiments, at least one boss 323 is provided with a first limiting protrusion 325 protruding towards the end face of the connecting member 37, and at least one first connecting portion 371 is provided with a second limiting protrusion 371a protruding from its outer peripheral surface. For example, two bosses 323 are respectively provided with the first limiting protrusion 325, and two first connecting portions 371 are respectively provided with the second limiting protrusion 371a. The second limiting protrusion 371a is used to abut against the first limiting protrusion 325 to restrict the rotation of the second shaft 36 relative to the second shaft hole 324. That is, during the process of the main body 2 flipping relative to the support bracket 1, the second limiting protrusion 371a will rotate with the main body 2. When the second limiting protrusion 371a rotates to abut against the first limiting protrusion 325, the second shaft 36 cannot continue to rotate relative to the second shaft hole 324 in the original direction of rotation. At this time, the main body 2 also cannot continue to rotate in the original direction of rotation, so as to avoid the main body 2 flipping too much relative to the support bracket 1, which would cause the side of the main body 2 facing away from the support bracket 1 (i.e. the side where the display screen of the main body 2 is located) to interfere with the support bracket 1, thereby avoiding damage to the main body 2 and playing a role in protecting the main body 2.

[0133] Understandably, the maximum rotation angle of the main body 2 relative to the support bracket 1 can be limited by adjusting the position of the first limiting protrusion 325 on the end face of the boss 323 facing the connecting component 37. For example, when the first limiting protrusion 325 is set at the top of the boss 323 away from the support bracket 1, the maximum rotation angle of the main body 2 relative to the support bracket 1 can be controlled at about 90°. For example, the maximum rotation angle of the main body 2 relative to the support bracket 1 can be 87°, 87.5°, 88°, 88.5°, 89°, 89.5°, 90°, 90.5°, 91°, 91.5°, 92°, 92.5°, 93°, etc.

[0134] In some embodiments, the rotating connection structure 3 further includes a damping component 38, which is sleeved on the outer periphery of the second shaft 36 and pressed between the second shaft 36 and the inner wall surface of the second shaft hole 324. The damping component 38 is used to provide a damping force to maintain the second shaft 36 in its state after rotation relative to the second shaft hole 324.

[0135] By inserting a damping component 38 into the gap between the second shaft hole 324 of the boss 323 and the second shaft body 36 through an interference fit, the outer surface of the second shaft body 36 and the inner circumferential surface of the damping component 38 can be interfered with to generate damping. This not only allows the main body 2 to be flipped relative to the bottom bracket using the second shaft body 36, but also allows the main body 2 to be fixed at any flip angle using the damping component 38, so that the main body 2 can be kept at the current angle for the user to operate.

[0136] Optionally, the damping component 38 is a spring or an elastic ring structure made of an elastic material, wherein the elastic ring structure made of an elastic material can be a silicone ring or a rubber ring, etc.

[0137] In this application, the connection between the connector 31 and the support bracket 1 can be either non-detachable or detachable.

[0138] Preferably, the connection between the connector 31 and the support bracket 1 is detachable. This allows the main unit 2 to be removed from the support bracket 1, making it easier to adjust the orientation of the camera on the main unit 2 to meet the user's operational needs in different usage scenarios. This improves operability and adaptability, facilitating functions such as calls and photography, and enhancing user convenience when using the smart wearable device. Especially when making calls while wearing the smart wearable device, it replaces the method in related technologies where the arm needs to be raised to bring the main unit 2 close to the user's ear. Instead, the main unit 2 can be detached from the bracket and brought close to the user's ear for calls. This method not only makes it easier for users to make calls while wearing the smart wearable device, providing a comfortable user experience, but also helps dissipate heat from the main unit 2 during long calls, preventing burns to the user's skin.

[0139] To facilitate the removal of the main unit from the support bracket 1, such as Figure 12 As shown, the support bracket 1 is provided with a plug-in groove 11, and the rotating connection structure also includes a locking member 39a. The locking member 39a is provided on the connector 31 and is plugged into the plug-in groove 11, so that the connector 31 is detachably connected to the support bracket 1, so that the connector 31 can be removed from the support bracket 1, thereby allowing the main body to be removed from the support bracket 1.

[0140] Since the connector 31 and the support bracket 1 are connected by a snap-fit, the connector 31 can be removed from the support bracket 1 without the need for tools, unlike the threaded connection. Therefore, the connection 31 and the support bracket 1 can be removed without the need for disassembly or assembly tools, which makes it convenient to remove the main body 2 from the support bracket 1.

[0141] In some embodiments, the support bracket 1 further includes a connecting groove 12, wherein the aforementioned insertion groove 11 is disposed on the side wall of the connecting groove 12, and the connector 31 is embedded in the connecting groove 12. The connector 31 can be detachably embedded in the connecting groove 12 through the cooperation of the locking member 39a and the insertion groove 11. By providing the connecting groove 12 on the support bracket 1, the mounting position of the connector 31 on the support bracket 1 can be defined by the connecting groove 12. Therefore, when the main unit 2 is installed onto the support bracket 1, the cooperation between the connecting groove 12 and the connector 31 facilitates the installation of the main unit 2 onto the support bracket 1.

[0142] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, the connector 31 has an internal receiving groove 312, and the connector 31 is provided with a third shaft hole 313 extending along the thickness direction f3, through which the first shaft 33 is rotatably inserted; the connector 31 is also provided with a through hole 314 extending along the length direction f1 or the width direction f2, through which the locking member 39a is slidably inserted. The rotating connection structure 3 also includes an elastic reset member 39b and a cam 39c. The elastic reset member 39b is disposed in the receiving groove 312 and connected to the locking member 39a, and the cam 39c is connected to the first shaft 33 and located in the receiving groove 312.

[0143] When the first shaft 33 rotates until the arcuate side of the cam 39c abuts against the locking member 39a, the cam 39c drives the locking member 39a to slide relative to the through hole 314 to the outside of the receiving groove 312, so that the locking member 39a is embedded in the insertion groove 11, thereby fixing the connector 31 in the connecting groove 12. During this process, the elastic reset member 39b is compressed or stretched. When the first shaft 33 rotates until the arcuate side of the cam 39c separates from the locking member 39a, the elastic reset member 39b undergoes a restorative change and drives the locking member 39a to slide relative to the through hole 314 to the inside of the receiving groove 312, so that the locking member 39a separates from the insertion groove 11, thereby allowing the connector 31 to disengage from the connecting groove 12, and allowing the main body 2 to be detached from the support bracket 1.

[0144] Since the user needs to rotate the main unit 2 relative to the support bracket 1 by a predetermined angle around the central axis of the first shaft 33 when detaching the main unit 2 from the support bracket 1, this design reduces the possibility of accidental operation compared to using magnetic attraction, snap-fit ​​or other methods to achieve detachable connection between the main unit 2 and the support bracket 1. The possibility of the main unit 2 separating from the support bracket 1 without the user's subjective intention is lower. This is especially true for children and teenagers, as it avoids accidental disassembly of the main unit 2 from the support bracket 1 and also prevents the main unit 2 from accidentally falling off the support bracket 1 and causing injury.

[0145] In addition, a receiving groove 312 is provided inside the connector 31 to accommodate components such as the locking component 39a, the elastic reset component 39b, and the cam 39c. This not only protects the components such as the locking component 39a, the elastic reset component 39b, and the cam 39c, but also makes the structure of the smart host 100 more compact and conforms to miniaturization design.

[0146] It is worth noting that when there is a protrusion 311 and a recess, when the locking member 39a is inserted into the insertion slot 11, the protrusion is not embedded in the recess. Thus, when the first shaft 33 rotates relative to the third shaft hole 313 to a preset angle, the protrusion 311 is embedded in the recess, so that the user knows that the main body 2 has been rotated to the preset angle and knows that the main body 2 can be removed from the support bracket 1 at this time.

[0147] Optionally, the elastic reset member 39b may be a spring or an elastic columnar structure made of an elastic material, wherein the elastic columnar structure made of an elastic material may be a silicone column or a rubber column, etc.

[0148] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, the insertion groove 11 includes a first sub-insertion groove 111 and a second sub-insertion groove 112. The first sub-insertion groove 111 and the second sub-insertion groove 112 are respectively disposed on the two side walls of the connecting groove 12 in the length direction f1. The through hole 314 includes a first sub-through hole 314a and a second sub-through hole 314b. The first sub-through hole 314a and the second sub-through hole 314b are respectively located on both sides of the connector 31 in the length direction f1. The locking member 39a includes a first locking component 39a1 and a second locking component 39a2. The first locking component 39a1 is slidably inserted through the first sub-through hole 314a, and the second locking component 39a2 is slidably inserted through the second sub-through hole 314b. There is one cam 39c, which is located between the first locking component 39a1 and the second locking component 39a2.

[0149] When the first shaft 33 rotates until the arcuate side of the cam 39c abuts against the first locking component 39a1 and the second locking component 39a2, the cam 39c drives the first locking component 39a1 to slide relative to the first sub-through hole 314a to be located outside the receiving groove 312, and drives the second locking component 39a2 to slide relative to the second sub-through hole 314b to be located outside the receiving groove 312, so that the first locking component 39a1 is embedded in the first sub-insertion groove 111 and the second locking component 39a2 is embedded in the second sub-insertion groove 112, thereby fixing the connector 31 in the connecting groove 12.

[0150] When the first shaft 33 rotates to the point where the arcuate side of the cam 39c separates from the first locking component 39a1 and the second locking component 39a2, the elastic reset component 39b drives the first locking component 39a1 to slide relative to the first sub-through hole 314a into the receiving groove 312, and drives the second locking component 39a2 to slide relative to the second sub-through hole 314b into the receiving groove 312, so that the first locking component 39a1 separates from the first sub-insertion groove 111 and the second locking component 39a2 separates from the second sub-insertion groove 112, thereby allowing the connector 31 to disengage from the connecting groove 12, and allowing the main body 2 to be disassembled from the support bracket 1.

[0151] The system is equipped with two locking components (i.e., the first locking component 39a1 and the second locking component 39a2) and two sub-plug slots (i.e., the first sub-plug slot 111 and the second sub-plug slot 112). When the connector 31 is installed into the connecting slot 12 of the support bracket 1, the mutual plugging of the two locking components and the two sub-plug slots can improve the connection stability between the connector 31 and the plug slot 11, thereby improving the connection stability between the main body 2 and the support bracket 1.

[0152] In addition, this application provides a cam 39c, which drives two locking components to slide into the corresponding sub-slots. Compared with the method of providing two cams 39c arranged along the thickness direction f3, this not only reduces the size of the rotating connection structure 3 in its thickness direction f3 (for example, the size of the rotating connection structure 3 in its width direction f2 can be reduced from the original range of 7.4mm-9.2mm to the range of 5.6mm-7.3mm, and exemplarily, the size of the rotating connection structure 3 in its width direction f2 can be reduced from the original range of 8.2mm to 7.2mm), but also reduces the size of the rotating connection structure 3 in its length direction f1 (for example, the size of the rotating connection structure 3 in its length direction f1 can be reduced from the original range of 6.5mm-8.4mm to the range of 4mm-6.4mm, and exemplarily, the size of the rotating connection structure 3 in its length direction f1 can be reduced from the original range of 7.5mm to 5.8mm), thereby further realizing the miniaturization design of the rotating connection structure 3.

[0153] Optionally, each locking component may be provided with a first sub-locking part 39a3 and a second sub-locking part 39a4 spaced apart, and each sub-insertion groove may include a first sub-groove 113 and a second sub-groove 114 spaced apart, with the first sub-locking part 39a3 inserted into the first sub-groove 113 and the second sub-locking part 39a4 inserted into the second sub-groove 114.

[0154] By providing a first sub-locking part 39a3 and a second sub-locking part 39a4 to each locking component, and by including a first sub-groove 113 and a second sub-groove 114 in each sub-insertion slot, when the connector 31 is installed into the connection slot 12 of the support bracket 1, each locking component and each sub-insertion slot can be inserted through two sub-locking parts and corresponding sub-grooves. This helps to further improve the connection stability between the connector 31 and the insertion slot 11, and further improves the connection stability between the main body 2 and the support bracket 1.

[0155] In some embodiments, the resilient reset member 39b is connected between the first locking member 39a1 and the second locking member 39a2.

[0156] When the first shaft 33 rotates until the arcuate side of the cam 39c abuts against the first locking component 39a1 and the second locking component 39a2, the cam 39c drives the first locking component 39a1 to slide relative to the first sub-through hole 314a to the outside of the receiving groove 312, and drives the second locking component 39a2 to slide relative to the second sub-through hole 314b to the outside of the receiving groove 312, so that the first locking component 39a1 is embedded in the first sub-insertion groove 111 and the second locking component 39a2 is embedded in the second sub-insertion groove 112, thereby fixing the connector 31 in the connecting groove 12. During this process, the first locking component 39a1 and the second locking component 39a2 move away from each other and stretch the elastic reset component 39b to deform it.

[0157] When the first shaft 33 rotates until the arcuate side of the cam 39c separates from both the first locking component 39a1 and the second locking component 39a2, the elastic reset component 39b restores its deformation and drives the first locking component 39a1 to slide relative to the first sub-through hole 314a into the receiving groove 312, and drives the second locking component 39a2 to slide relative to the second sub-through hole 314b into the receiving groove 312. This separates the first locking component 39a1 from the first sub-insertion groove 111 and the second locking component 39a2 from the second sub-insertion groove 112, allowing the connector 31 to disengage from the connecting groove 12 and the main body 2 to be detached from the support bracket 1. During this process, the first locking component 39a1 and the second locking component 39a2 move closer to each other.

[0158] Optionally, there may be multiple elastic reset members 39b, such as two, three, four, etc. Each elastic reset member 39b is connected between the first locking member 39a1 and the second locking member 39a2, thereby increasing the elastic force of the elastic reset member to ensure that the elastic reset member 39b can smoothly drive the first locking member 39a1 and the second locking member 39a2 to slide into the receiving groove 312, thereby ensuring that the main body 2 can be smoothly removed from the support bracket 1.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
