Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, and more particularly to a button structure and a smart wearable device. Background Technology

[0002] With the continuous advancement of technology, smart wearable devices have become essential tools in people's daily lives, and their functional diversity continues to expand. To meet users' needs in different scenarios, the main unit of a smart wearable device often needs to rotate or detach from the wearable components. For example, in sports scenarios, users may need to remove the smart main unit from the wearable components to perform other operations; during daily wear, the rotation of the smart main unit facilitates video calls or other operations. This design greatly improves the flexibility and user experience of smart wearable devices.

[0003] However, this design also presents new challenges. When the user does not need the smart unit to move, such as during normal walking or other activities, the natural swinging of the arm may cause the smart unit to rotate unexpectedly or even detach from the wearable device. This not only affects the normal use of the device but may also damage the smart unit, resulting in financial losses for the user. Utility Model Content

[0004] The purpose of this application is to provide a button structure and a smart wearable device that not only enables the smart host to maintain a relatively fixed state relative to the wearable components, but also occupies little space and is easy to install and arrange in devices such as smart hosts.

[0005] The technical solution provided in this application is as follows:

[0006] On one hand, a button structure is provided for use in a smart wearable device, the smart wearable device including a smart host and a buckle, wherein the button structure includes:

[0007] A button bracket includes a rotating part and a pressing part. One end of the rotating part is bent to form a fastening part, and the other end of the rotating part is bent to form an annular part. The connection between the pressing part and the rotating part is located between the fastening part and the annular part.

[0008] A rotating shaft passes through the annular portion and is used for fixed connection with the smart host.

[0009] The reset component has one end for connecting to the smart host and the other end abutting against the rotating part;

[0010] When the pressing part is pressed, the rotating part is driven to rotate around the rotating shaft, thereby unlocking the fastening part from the buckle; when the pressing part is released, the rotating part is reset under the action of the reset member, thereby unlocking the fastening part from the buckle.

[0011] In some embodiments, the button bracket is a stamped part.

[0012] In some embodiments, the fastening portion and the annular portion are located on the same side of the rotating portion;

[0013] Alternatively, the fastening part is located on one side of the rotating part, and the annular part is located on the other side of the rotating part.

[0014] In some embodiments, the rotating shaft is U-shaped, with one end of the rotating shaft passing through the annular portion and the other end of the rotating shaft being fixedly connected to the smart host by screws;

[0015] Alternatively, it may also include a fixing bracket, wherein the rotating shaft is a strip structure, and the rotating shaft passes through the annular portion and is fixed to the smart host by the fixing bracket.

[0016] In some implementations, a button and a button limiting member are also included;

[0017] The button limiting component is used to fix it to the smart host. The button limiting component is provided with a mounting hole. The button is adapted to the mounting hole, and one side of the button passes through the mounting hole. The other side of the button is provided with a limiting structure. The limiting structure cooperates with the mounting hole to prevent the button from coming out of the mounting hole.

[0018] The button is configured to correspond to the pressing part, and pressing the button will press the pressing part.

[0019] In some embodiments, the pressing part has a protrusion with a semi-circular cross-section on the side near the button.

[0020] In some embodiments, the rotating part includes a first rotating part and a second rotating part, and one end of the pressing part is connected to the first rotating part and the other end is connected to the second rotating part;

[0021] One end of the first rotating part and the second rotating part are bent to form the fastening part, and the other end of the first rotating part and the second rotating part are bent to form the annular part.

[0022] In some embodiments, the first rotating part is provided with a first limiting part, and the second rotating part is provided with a second limiting part. The first limiting part and the second limiting part cooperate with the smart host to prevent the first rotating part and the second rotating part from detaching from the smart host.

[0023] In some embodiments, the first rotating part and the second rotating part are respectively provided with strip-shaped holes for the positioning post on the smart host to pass through.

[0024] On the other hand, a smart wearable device is also provided, including a smart host, a buckle, a wearable component, and a button structure as described in any of the above embodiments. The buckle is disposed on the wearable component, and the button structure is disposed on the smart host. When the fastening part is engaged with the buckle, the smart host is fixed to the wearable component.

[0025] The technical advantages of this application are as follows: When the fastening part is engaged with the buckle, the smart host can be firmly fixed to the wearable component, preventing accidental rotation or detachment due to arm swinging or other external forces, and reducing vibration and shaking of the smart host during wear, significantly improving the stability and lifespan of the device during normal use. When the fastening part is disengaged from the buckle, the smart host is released from the fixed connection with the wearable component, allowing the smart host to be detached from the wearable component or flipped relative to it, enabling users to quickly and conveniently adjust the wearing status of the device to meet the needs of different scenarios. Furthermore, the button structure of this application integrates the rotating part and the pressing part into one unit, and through the structural design of the annular part and the fastening part, it achieves functional centralization, making the entire button structure compact, space-saving, and easy to install and arrange in devices such as smart hosts.

[0044] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) are relative rather than absolute when describing the structure and movement of the various components, and are not intended to limit the direction of the product during actual use.

[0045] Furthermore, in the description of this application, ordinal numbers, such as "first" and "second," are used only to distinguish related objects and should not be construed as indicating or implying the relative importance or order between related objects.

[0046] like Figures 1 to 3 As shown, this disclosure provides a button structure applied to a smart wearable device. The smart wearable device includes a smart host 200 and a buckle 400 disposed on a wearable component 300. The button structure 100 is installed on the smart host 200. When the button structure 100 is unlocked from the buckle 400, the smart host 200 can be detached from the wearable component 300 or flipped relative to the wearable component 300. When the button structure 100 is engaged with the buckle 400, the smart host 200 can be fixed to the wearable component 300 to prevent the smart host 200 from accidentally rotating or detaching from the wearable component 300 when the arm swings naturally.

[0047] In some embodiments, such as Figures 3 to 5 As shown, the button structure 100 includes a button support 110, a rotating shaft 120, and a reset member 130. The button support 110 includes a rotating part 111 and a pressing part 112. One end of the rotating part 111 is bent to form a fastening part 113, and the other end of the rotating part 111 is bent to form an annular part 114. The connection between the pressing part 112 and the rotating part 111 is located between the fastening part 113 and the annular part 114. The rotating shaft 120 passes through the annular part 114 and is used to fix it to the smart host 200. One end of the reset member 130 is used to connect to the smart host 200, and the other end abuts against the rotating part 111. When the pressing part 112 is pressed, it drives the rotating part 111 to rotate around the rotating shaft 120, thereby unlocking the fastening part 113 from the latch 400. When the pressing part 112 is released, the rotating part 111 is reset under the action of the reset member 130, thereby unlocking the fastening part 113 from the latch 400.

[0048] Specifically, the button bracket 110 includes a rotating part 111 and a pressing part 112. One end of the rotating part 111 is bent to form a fastening part 113, which is used to cooperate with an external latch 400 to achieve a locking or unlocking function. The other end of the rotating part 111 is bent to form an annular part 114, which is used to install a rotating shaft 120, so that the entire rotating part 111 can rotate around the rotating shaft 120. The pressing part 112 is connected to the rotating part 111. When the user presses the pressing part 112, it can drive the rotating part 111 to rotate around the rotating shaft 120, so that the fastening part 113 unlocks from the latch 400.

[0049] The rotating shaft 120 passes through the annular portion 114 and is fixedly connected to the smart host 200, serving to support and fix the button bracket 110 while allowing the rotating part 111 to rotate around it. The outer diameter of the rotating shaft 120 matches the inner diameter of the annular portion 114 to ensure that the rotating shaft 120 can be stably installed within the annular portion 114 and to allow the rotating part 111 to rotate freely around the rotating shaft 120. Preferably, the rotating shaft 120 and the annular portion 114 are clearance-fitted to reduce friction and ensure smooth rotation of the rotating part 111.

[0050] The reset component 130 is located between the smart host 200 and the button structure 100. The function of the reset component 130 is to enable the rotating part 111 to automatically return to its initial position after the rotating part 111 rotates under the action of external force. The reset component 130 is usually implemented by elastic elements such as springs.

[0051] The working process of the button structure 100 in this embodiment is as follows: When unlocking, the user presses the pressing part 112, and the force of the pressing part 112 is transmitted to the rotating part 111, causing the rotating part 111 to rotate around the rotating shaft 120. The fastening part 113 moves accordingly and unlocks with the external buckle 400. At this time, the reset member 130 is compressed or stretched, storing elastic potential energy, and the smart host 200 and the wearable component 300 are in the unlocked state. After the user releases the pressing part 112, the reset member 130 releases the elastic potential energy, and the elastic force of the reset member 130 acts on the rotating part 111, causing the rotating part 111 to rotate in the opposite direction around the rotating shaft 120. The fastening part 113 engages with the buckle 400 again to complete the locking operation.

[0052] In this embodiment, the button structure 100 allows users to unlock the device simply by pressing the pressing part 112. Upon release, it automatically resets and locks, making operation simple and intuitive and improving user experience. The fixed connection between the rotating shaft 120 and the smart host 200, along with the elastic support of the reset component 130, ensures the stability and reliability of the button structure 100 during operation, reducing structural damage caused by external forces or misoperation. The button bracket 110 integrates the rotating part 111 and the pressing part 112 into one unit. Through the structural design of the annular part 114 and the fastening part 113, the functions are centralized, resulting in a compact button structure that occupies little space and facilitates installation and layout in devices such as the smart host 200.

[0053] In some embodiments, the button holder 110 is a stamped part. Most existing button holders are manufactured using powder metallurgy through pressing and sintering, which is not only complex in production but also expensive. In this embodiment, the button holder 110 mainly consists of a rotating part 111 and a pressing part 112. Its shape and size are relatively regular, and the fastening part 113 and the annular part 114 at both ends of the rotating part 111 can also be easily formed by bending in the stamping process, allowing the entire button holder 110 to be formed by stamping. Stamping is a highly efficient production method; through one-time forming with a mold, it can quickly produce a large number of parts with consistent shapes. Compared to the pressing and sintering processes of powder metallurgy, stamping has higher production efficiency. Furthermore, stamping dies have relatively low cost and long service life, resulting in lower costs per part. Moreover, stamping does not require complex sintering equipment and high-temperature treatment, further reducing production costs.

[0054] In some embodiments, such as Figure 6 As shown, the fastening portion 113 and the annular portion 114 are located on the same side of the rotating portion 111. Placing the fastening portion 113 and the annular portion 114 on the same side of the rotating portion 111 makes the overall structure of the button bracket 110 more compact. This layout reduces the horizontal space occupied by the button bracket 110, allowing the button structure 100 to better adapt to space-constrained internal environments, such as in miniaturized devices like the smart host 200, thus saving valuable internal space.

[0055] In some embodiments, such as Figure 7As shown, the engaging portion 113 is located on one side of the rotating portion 111, and the annular portion 114 is located on the other side of the rotating portion 111. Placing the engaging portion 113 and the annular portion 114 on opposite sides of the rotating portion 111 results in a more balanced torque distribution when the rotating portion 111 rotates around the axis 120. When the pressing portion 112 is pressed down, the engaging portion 113 and the annular portion 114 are positioned on opposite sides of the rotating portion 111. This symmetrical arrangement reduces skewing and shaking during rotation, making the rotation smoother. Simultaneously, placing the engaging portion 113 and the annular portion 114 on opposite sides of the rotating portion 111 provides a greater stroke for both the rotating portion 111 and the engaging portion 113, facilitating the unlocking of the engaging portion 113 from the latch 400.

[0056] In some embodiments, such as Figures 3 to 5 As shown, the hinge 120 is U-shaped. One end of the hinge 120 passes through the annular portion 114, and the other end is fixedly connected to the smart host 200 by a screw 140. The U-shape of the hinge 120 means it has two parallel legs with a certain distance between them. One leg passes through the annular portion 114 of the button bracket 110, and the other leg is fixedly connected to the smart host 200 by the screw 140. A U-shaped groove can be provided on the smart host 200, and the hinge 120 is installed within this groove to facilitate its installation.

[0057] In this embodiment, the rotating shaft 120 has a U-shaped design, which allows it to be fixed using only screws 140, eliminating the need for other fasteners, thus reducing the number of parts and lowering production costs. Furthermore, during use, the force on the rotating shaft 120 can be distributed to the two support legs, reducing stress concentration and improving the overall strength and durability of the structure.

[0058] In some embodiments, such as Figure 8 and Figure 9 As shown, the button structure 100 also includes a fixing bracket 150. The rotating shaft 120 is a strip structure. The rotating shaft 120 passes through the annular portion 114 and is fixed to the smart host 200 by the fixing bracket 150. The rotating shaft 120 is fixed to the smart host 200 by the fixing bracket 150 and bolts, which can improve the fixing stability and reliability of the rotating shaft 120.

[0059] In some embodiments, such as Figure 1 and Figure 2As shown, the button structure 100 also includes a button 160 and a button limiting member 170; the button limiting member 170 is used to be fixedly connected to the smart host 200, and the button limiting member 170 is provided with a mounting hole 171. The button 160 is adapted to the mounting hole 171, and one side of the button 160 passes through the mounting hole 171. The other side of the button 160 is provided with a limiting structure 161, which cooperates with the mounting hole 171 to prevent the button 160 from coming out of the mounting hole 171; the button 160 is correspondingly provided with a pressing part 112, and when the button 160 is pressed, the pressing part 112 is pressed.

[0060] The button limiting component 170 is fixedly connected to the smart host 200, serving to support and limit the movement of the button 160. The button limiting component 170 has a mounting hole 171, the size and shape of which are adapted to the button 160, ensuring that a portion of the button 160 can smoothly pass through the mounting hole 171, and that the button 160 can move horizontally relative to the button limiting component 170. A limiting structure 161 is provided on the outer wall of the button 160. After the button 160 is installed in the mounting hole 171, the outer diameter of the limiting structure 161 is larger than the inner diameter of the mounting hole 171, preventing the button 160 from dislodging from the mounting hole 171 in the horizontal direction, while allowing the button 160 to be pressed in the horizontal direction. Button 160 is configured to correspond to pressing part 112. When button 160 is pressed, button 160 moves horizontally and comes into contact with pressing part 112, so as to accurately transmit the pressing force to pressing part 112, thereby driving rotating part 111 to rotate around rotating shaft 120, making button 160 operation more precise and improving user experience.

[0061] In this embodiment, a button 160 is provided outside the pressing part 112, which makes it easier for the user to press and improves the user experience. The cooperation between the limiting structure 161 and the mounting hole 171 reduces the shaking and friction of the button 160 during operation, extends the service life of the button 160, and reduces the risk of failure due to wear. The design of the button limiting component 170 makes the installation process of the button 160 very simple. The operator only needs to pass the button 160 through the mounting hole 171 and ensure that the limiting structure 161 cooperates with the mounting hole 171, which reduces the installation steps and time.

[0062] In some embodiments, such as Figure 6 and Figure 7 As shown, the pressing part 112 has a protrusion 1121 with a semi-circular cross-section on the side near the button 160.

[0063] The pressing part 112 has a semi-circular protrusion 1121 on the side near the button 160. When the semi-circular protrusion 1121 contacts the button 160, the contact point is an arc surface instead of a plane. When the button 160 moves horizontally and drives the pressing part 112 and the rotating part 111 to rotate, this arc surface contact method can effectively reduce the contact area between the button 160 and the pressing part 112, thereby reducing friction and improving the feel.

[0064] In some embodiments, such as Figure 6 and Figure 7 As shown, the rotating part 111 includes a first rotating part 1111 and a second rotating part 1112. One end of the pressing part 112 is connected to the first rotating part 1111, and the other end is connected to the second rotating part 1112. One end of the first rotating part 1111 and the second rotating part 1112 are respectively bent to form a fastening part 113, and the other end of the first rotating part 1111 and the second rotating part 1112 are respectively bent to form an annular part 114.

[0065] The pressing part 112 is connected to the first rotating part 1111 and the second rotating part 1112 at both ends. Pressing the pressing part 112 simultaneously drives the first rotating part 1111 and the second rotating part 1112 to rotate, ensuring the uniformity and consistency of the button 160 operation and improving the symmetry and stability of the entire button bracket 110, reducing shaking and tilting during rotation. The first rotating part 1111 and the second rotating part 1112 are each provided with annular parts 114. Each of the two annular parts 114 is rotatably connected to the smart host 200 via a rotating shaft 120 and is reset via a reset component 130. The first rotating part 1111 and the second rotating part 1112 are each provided with a fastening part 113. The wearable component 300 is provided with two buckles 400. The two fastening parts 113 are respectively engaged with the two buckles 400. This double fastening part 113 design increases the reliability and stability of the structure.

[0066] Furthermore, such as Figure 6 and Figure 7 As shown, the first rotating part 1111 is provided with a first limiting part 1113, and the second rotating part 1112 is provided with a second limiting part 1114. The first limiting part 1113 and the second limiting part 1114 cooperate with the smart host 200 to restrict the first rotating part 1111 and the second rotating part 1112 from detaching from the smart host 200.

[0067] In this embodiment, the first limiting part 1113 is a limiting structure formed by extending a portion of the first rotating part 1111 outward, and the second limiting part 1114 is a limiting structure formed by extending a portion of the second rotating part 1112 outward. Two limiting slots can be provided on the smart host 200. Through the cooperation of the first limiting part 1113 and the second limiting part 1114 with the corresponding limiting slots, the entire button bracket 110 can be limited to prevent it from disengaging.

[0068] Furthermore, such as Figure 6 and Figure 7 As shown, the first rotating part 1111 and the second rotating part 1112 are respectively provided with strip-shaped holes 115 for the positioning posts 210 on the smart host 200 to pass through. The smart host 200 is provided with two positioning posts 210, and the first rotating part 1111 and the second rotating part 1112 are respectively provided with strip-shaped holes 115. Through the cooperation of the two positioning posts 210 and the two strip-shaped holes 115, the button bracket 110 can be positioned during installation. The holes on the first rotating part 1111 and the second rotating part 1112 are strip-shaped holes 115, and the vertical dimension of the strip-shaped holes 115 is larger than the dimension of the positioning posts 210, ensuring that the first rotating part 1111 and the second rotating part 1112 can rotate smoothly.

[0069] Furthermore, such as Figure 5 As shown, the two reset pieces 130 can be respectively fitted onto the two positioning posts 210. The positioning posts 210 provide stable support for the reset pieces 130, ensuring that the reset pieces 130 will not shift or tilt during operation. This stable support allows the reset pieces 130 to apply force more accurately, thereby improving the reset accuracy of the button 160.

[0070] In some embodiments, a smart wearable device is also provided, such as Figures 1 to 9 As shown, the device includes a smart host 200, a wearable component 300, a buckle 400, and a button structure 100 as described in any of the above embodiments. The buckle 400 is disposed on the wearable component 300, and the button structure 100 is disposed on the smart host 200. When the fastening part 113 is engaged with the buckle 400, the smart host 200 is fixed to the wearable component 300.

[0071] In this embodiment, the smart host 200 includes a housing and electronic components and functional modules disposed within the housing. The wearable component 300 is the part that directly contacts the user. The wearable component 300 can be a tray for mounting the smart host 200, or a watch strap, wristband, etc., for fixing the smart host 200 to the user's wrist. In this embodiment, the button structure 100 is mounted on the housing of the smart host 200, and the buckle 400 is fixed to the wearable component 300; this is a simple variation. Alternatively, the button structure 100 can be fixed to the wearable component 300, and the buckle 400 can be fixed to the smart host 200, which is also within the scope of protection of this embodiment.

[0072] When the fastening part 113 engages with the buckle 400, the smart host 200 is securely fixed to the wearable component 300, preventing accidental rotation or detachment due to arm swinging or other external forces. This also reduces vibration and shaking of the smart host 200 during wear, significantly improving the stability and lifespan of the device under normal use. When the fastening part 113 disengages from the buckle 400, the smart host 200 is released from its fixed connection with the wearable component 300, allowing it to be detached from or flipped relative to the wearable component 300. This enables users to quickly and conveniently adjust the device's wearing status to meet the needs of different scenarios.

[0073] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0074] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
