Abstract
Description
Technical Field
[0001] This application relates to the field of electronic device technology, and more particularly to a connection structure and a wearable device. Background Technology
[0002] In recent years, wearable devices have gradually developed towards lightweight and personalized designs. However, the connection structures of wearable devices such as AR glasses, VR glasses, MR glasses, or audio glasses generally suffer from the following technical bottlenecks: Traditional connection structures mostly adopt a fixed angle design, with the temple angle limited to a fixed range that cannot be adjusted. This results in significant pressure for users with larger head circumferences, while users with smaller head circumferences are prone to the frames slipping down, affecting the user experience. Although some related technologies employ springs or elastic sheets, these elastic components only provide the restoring force when the temples open and lack the function of dynamically changing the temple angle range, resulting in the clamping force not being able to dynamically adapt to different wearers.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0039] The following is combined with Figures 1 to 9 This application describes the connection structure 1 and wearable device provided in the embodiments. The wearable device includes, but is not limited to, smart glasses, smartwatches, smart bracelets, etc., and may also be other devices that use the connection structure 1 to adjust the wearing clamping force of the wearable device. The embodiments of this application do not specifically limit the specific type of wearable device.
[0040] Taking smart glasses as an example, such as Figures 1 to 7As shown, the smart glasses include a connection structure 1, which comprises a pivot seat 12 and a pivot arm 11. One side of the pivot seat 12 is rotatably connected to the connecting portion 113 of the pivot arm 11, and the other side of the pivot seat 12 is provided with an elastic component 121. One side of the main body 110 of the pivot arm 11 is provided with an adjusting member 111. When the pivot arm 11 is in the extended state relative to the pivot seat 12, one end of the elastic component 121 abuts against the pivot seat 12, and the other end of the elastic component 121 abuts against the adjusting member 111. The adjusting member 111 can move relative to the pivot arm 11 in a first direction (towards or away from the pivot seat 12) to adjust the angle of the pivot arm 11 when it is in the extended state relative to the pivot seat 12. Since one of the pivot seat 12 and the pivot arm 11 is connected to the extension portion 21 of the frame 2 and the other is connected to the temple 3, the angle of the temple 3 when it is in the extended state relative to the frame 2 can be adjusted.
[0041] In this embodiment, the adjusting member 111 has the ability to move relative to the rotating arm 11 in a first direction (i.e., the direction of approaching or moving away from the rotating seat 12). It is through this movement of the adjusting member 111 that the angle of the rotating arm 11 when it is in the unfolded state relative to the rotating seat 12 is precisely controlled.
[0042] Specifically, when the adjusting member 111 moves, it controls the deformation of the elastic component 121, adjusts the force between the pivot arm 11 and the pivot seat 12, and causes the pivot arm 11 to rotate around the rotation connection point with the pivot seat 12, thereby adjusting the angle of the temple 3 relative to the frame 2 when it is in the unfolded state. Since the pivot seat 12 and the pivot arm 11 are respectively connected to the extension 21 of the frame 2 and the temple 3, the adjustment of the angle of the pivot arm 11 is directly converted into a change in the opening angle between the temple 3 and the frame 2.
[0043] like Figure 9 As shown, the pivot arm 11 is connected to the temple 3, and the pivot seat 12 is connected to the extension 21 of the frame 2. The relative angle between the adjusting member 111 on the pivot arm 11 and the pivot seat 12 is α, and the opening angle between the temple 3 and the frame 2 is θ. When the adjusting member 111 is adjusted, the displacement A of the adjusting member 111 will change, which will cause the included angle α to change. The pivot arm 11 will cause the opening angle between the temple 3 and the frame 2 to change. The change of the opening angle after the change is θ compared with the previous opening angle.
[0044] It is worth noting that the adjusting element 111 on the pivot arm 11 and the temple 3 fixed to the pivot arm 11 form a lever structure. During adjustment, the displacement A of the adjusting element 111 changes, causing a corresponding change in the included angle α, while the pivot arm 11 causes a change in the opening angle θ between the temple 3 and the frame 2. Due to the amplification effect of the lever, the small displacement A of the adjusting element 111 can be significantly amplified and transmitted to the temple 3, making the displacement B of the temple 3 significantly greater than the displacement A of the adjusting element 111. This lever amplification effect allows users to achieve a large change in the position of the temple 3 with a small adjustment force and displacement when adjusting the wearing state of the smart glasses, thus more easily adapting to different head circumferences and improving the comfort and adaptability of wearing smart glasses.
[0045] The connection structure 1 provided in this application includes a pivot seat 12 and a pivot arm 11. One side of the pivot seat 12 is rotatably connected to the connecting portion 113 of the pivot arm 11. An elastic component 121 is provided on the other side of the pivot seat 12. An adjusting member 111 is provided on one side of the main body 110 of the pivot arm 11. When the pivot arm 11 is in the extended state relative to the pivot seat 12, one end of the elastic component 121 abuts against the pivot seat 12, and the other end abuts against the adjusting member 111. In use, by controlling the distance the adjusting member 111 moves in the first direction of the pivot arm 11, the relative rotation of the pivot seat 12 and the pivot arm 11 can be dynamically adjusted using the elastic component 121 and the adjusting member 11. This adjusts the clamping force of the entire wearable device, ensuring a good fit while avoiding excessive tightness and discomfort for users with different head sizes, thus achieving personalized and comfortable wearing.
[0046] In addition to the embodiments described above, another connection method exists, in which the pivot arm 11 is connected to the extension 21 of the frame 2, and the pivot seat 12 is connected to the temple 3. In this case, the relative rotational relationship between the pivot arm 11 and the pivot seat 12 changes, and the pivot seat 12 will drive the temple 3 to rotate around the frame 2, thereby achieving the adjustment of the angle between the temple 3 and the frame 2. This design can also achieve the purpose of adjusting the opening angle between the temple 3 and the frame 2, providing more flexibility and selectivity for the structural design of smart glasses to meet the requirements of different design needs and application scenarios.
[0047] In some embodiments, such as Figures 1 to 3 As shown, when the pivot arm 11 is in a folded state relative to the pivot seat 12, or when the pivot arm 11 moves from an unfolded state to a folded state relative to the pivot seat 12, one end of the elastic component 121 extends beyond the pivot seat 12.
[0048] Specifically, when the user drives the pivot arm 11 to fold relative to the pivot seat 12, or during the folding process, the elastic component 121 changes from a first compressed state to a second compressed state (or a free state). The compression amount in the first compressed state is greater than that in the second compressed state, causing one end of the elastic component 121 to extend beyond the pivot seat 12. At this time, the deformation generated by the elastic component 121 provides elastic force, affecting the movement of the pivot arm 11. For example, during the folding process, the extended portion 21 of the elastic component 121 may abut against the adjusting member 111 on the pivot arm 11, thereby pushing it to move. That is, the elastic force of the elastic component 121 can provide some assistance for the folding of the pivot arm 11, making the folding smoother and less strenuous.
[0049] In some embodiments, such as Figures 1 to 7 As shown, on the other side of the pivot seat 12, a guide portion 122 and a support portion 123 are formed at intervals relative to each other in a first direction. The guide portion 122 faces the pivot arm 11, and the support portion 123 is away from the pivot arm 11. The guide portion 122 is provided with a guide hole 1221. The elastic component 121 includes a movable block 1211, one or more guide posts 1212 and one or more elastic elements 1213.
[0050] In this embodiment, the movable block 1211 is divided into three parts. The first part of the movable block 1211 extends out of one end of the guide portion 122 after passing through the guide hole 1221. The second part of the movable block 1211 abuts against the other end of the guide portion 122. The third part of the movable block 1211 is in the guide hole 1221.
[0051] One or more guide posts 1212 are located between the second movable block 1211 and the support part 123. One or more elastic elements 1213 are sleeved on one or more guide posts 1212. One end of the elastic element 1213 abuts against the support part 123, and the other end of the elastic element 1213 abuts against the second movable block 1211. The elastic element 1213 can deform along the first direction during the adjustment process of the adjusting member 111 by the guidance of the guide posts 1212.
[0052] Generally, the length of one or more guide posts 1212 in the first direction is less than the length between the second movable block 1211 and the support 123, so that after the elastic member 1213 is fitted onto the guide post 1212, the movement of the guide post 1212 and the movable block 1211 can be prevented from being obstructed.
[0053] In this embodiment, the elastic component 121 is provided with two guide posts 1212 and two elastic elements 1213. The two elastic elements 1213 are sleeved on the corresponding guide posts 1212. One end of the two elastic elements 1213 abuts against the support part 123, and the other end abuts against the second part of the movable block 1211, so that the elastic elements 1213 can provide stable elastic support force for the movable block 1211.
[0054] When the user controls the adjustment component 111 to move, the rotating arm 11 moves relative to the rotating seat 12, and the movable block 1211 moves in the guide hole 1221. The elastic element 1213 will be compressed or stretched, thereby generating a corresponding elastic force. This elastic force ensures that the first part of the movable block abuts against the adjustment component 111, so that after adjusting the position of the adjustment component 111, it affects the force balance of the rotating arm 11, causing the rotating arm 11 to rotate around the rotation connection point with the rotating seat 12, ultimately achieving the purpose of adjusting the angle of the temple 3 relative to the frame 2 when it is in the unfolded state.
[0055] To further ensure that the elastic element 1213 can deform along the first direction, such as Figures 4 to 7 As shown, the movable block 1211 is provided with one or more positioning posts 1214 relative to one or more guide posts 1212, and the other end of one or more elastic members 1213 is sleeved on the positioning posts 1214. The sum of the lengths of the one or more positioning posts 1214 and the one or more guide posts 1212 in the first direction is less than the length between the second part of the movable block 1211 and the support part 123.
[0056] In this embodiment, each positioning post 1214 corresponds to a guide post 1212. One end of the elastic element 1213 is sleeved on the outside of the positioning post 1214, and the other end of the elastic element 1213 is sleeved on the outside of the guide post 1212. Since the sum of the lengths of the positioning post 1214 and the guide post 1212 in the first direction is less than the length between the movable block 1211 and the support part 123, the elastic element 1213, when positioned between the positioning post 1214 and the guide post 1212, can prevent the movement of the positioning post 1214 and the guide post 1212 from being obstructed. Moreover, the two ends of the elastic element 1213 are limited by the guide post 1212 and the positioning post 1214. This limiting method can not only prevent the elastic element 1213 from shifting or twisting during deformation, but also accurately control the deformation range of the elastic element 1213.
[0057] When the rotating arm 11 moves, the elastic element 1213 is compressed between the guide post 1212 and the positioning post 1214. Its deformation is constrained by the positioning post 1214 and the guide post 1212, ensuring that the elastic element 1213 always deforms along a predetermined direction and path. This limiting effect helps improve the working reliability and lifespan of the entire elastic assembly 121, while also making the movement of the rotating arm 11 smoother and more precise.
[0058] Based on the above embodiments, in one example, such as Figure 3 and Figure 4 As shown, a protrusion 112 is provided on one side of the main body 110 of the rotating shaft arm 11. A threaded hole is formed on the protrusion 112 in a first direction. A threaded section is formed on the adjusting member 111. The adjusting member 111 engages with the threaded hole through the threaded section.
[0059] Generally, the protrusion 112 on the main body 110 is integrated with the pivot arm 11. The integrated pivot arm 11 can be achieved by metal powder metallurgy, metal die casting, metal milling, or by injection molding of hard plastic (such as fiber-reinforced nylon).
[0060] Adjusting component 111 uses an adjusting nut, the threaded section of which engages with the threaded hole on the protrusion 112 of the rotating arm 11. By manually rotating the adjusting nut, the user can change its position on the rotating arm 11, thereby adjusting the angle of the rotating arm 11 relative to the rotating seat 12, ultimately achieving adjustment of the opening angle between the two temples 3. The threaded connection has good self-locking properties; after adjustment, the adjusting nut can stably remain in the set position and is not easily loosened by daily activities or external forces, ensuring the stability of the angle between the temples 3 and the frame 2. The threaded engagement provides high adjustment precision; the user can precisely control the opening angle of the temples 3 by fine-tuning the position of the adjusting nut to accommodate users with different head circumferences.
[0061] For easy adjustment, a cross groove (or other groove type) can be provided on the adjusting nut, allowing users to adjust it with their fingers or simple tools, making it convenient and practical.
[0062] Based on the above embodiments, in one example, such as Figures 4 to 8 As shown, to reduce the overall weight, the pivot seat 12 and / or pivot arm 11 are provided with perforated process holes 127. By providing perforated process holes 127 on the pivot seat 12 and pivot arm 11, the amount of material used can be effectively reduced, thereby reducing the weight of the entire connection structure 1.
[0063] Furthermore, the pivot seat 12 and / or pivot arm 11 can also be made of thin-walled stamped parts. The design of thin-walled stamped parts makes the thickness of the metal seat as thin as possible, thereby minimizing the use of materials while ensuring structural strength, and achieving the goal of lightweighting.
[0064] In summary, by setting hollow process holes 127 on the pivot seat 12 and pivot arm 11 and adopting a thin-walled stamping part design, not only is the overall weight effectively reduced, but the structural performance is also optimized and the production cost is reduced.
[0065] In some embodiments, such as Figures 1 to 8As shown, the pivot seat 12 has two opposing folded edges 124 on one side, each folded edge 124 having a through hole. The connecting part 113 of the pivot arm 11 is rotatably located between the two folded edges 124. A pivot shaft 114 is located between the two folded edges 124 and the connecting part 113. The two folded edges 124 provide positioning and support points for the installation of the pivot shaft 114. At the same time, the structure of the folded edges 124 can increase the strength and rigidity of the pivot seat 12, making it more stable when subjected to the stress generated by the rotation of the pivot arm 11. The pivot shaft 114 passes through the through hole of the folded edge 124 and the connecting part 113 of the pivot arm 11, serving as the central axis of rotation, allowing the pivot arm 11 to rotate about it relative to the pivot seat 12.
[0066] In this embodiment, a fastener 126 is fixed to one end of the rotating shaft 114 and pressed against the outside of a folded edge 124. A washer 125 is provided between the fastener 126 and the folded edge 124. The washer 125 not only provides flatness and protection, but also engages with the edge of the fastener 126 (such as a pin or nut) through its surrounding flange, further enhancing the fixing effect and preventing the fastener 126 from loosening during use. The other end of the rotating shaft 114 has a flange 129, thereby locking both ends of the rotating shaft 114 together through the fastener 126 and the flange 129.
[0067] It should be noted that the rotating shaft 114 is secured between the rotating shaft seat 12 and the rotating shaft arm 11 using fasteners such as pins and nuts 126. During the fastening process, the magnitude of the fastening force can be precisely controlled, thereby adjusting the rotational torque and regulating the feel and stability of the temple 3 during control. During production, torque testing can be performed on each connection structure 1 to ensure that its rotational torque reaches the set fixed value. After reaching the set torque, the flange arm around the washer 125 is snapped onto the edge of the pin and nut, or the pin and nut are spot-welded to the rotating shaft 114, ensuring that the fasteners 126 will not loosen during long-term use. This consistent control ensures that the temple 3 of each pair of smart glasses provides the same natural stopping force during control, avoiding looseness or instability. The rotational torque, also known as the rotating shaft damping, plays a crucial role in the opening and closing of the temple 3. Appropriate rotating shaft damping allows the temple 3 to stop naturally when opening and closing, preventing a cheap feel due to excessive looseness. This damping effect not only improves the comfort of using smart glasses, but also enhances the product's perceived quality and reliability.
[0068] This application also provides a wearable device, such as... Figures 1 to 8As shown, the wearable device is a pair of smart glasses, including: a frame 2, temples 3, and a connecting structure 1; the frame 2 includes an extension 21 extending toward the temples 3, one of a pivot seat 12 and a pivot arm 11 being connected to the extension 21, and the other being connected to the temples 3, and the connecting part 113 of the pivot arm 11 being located in the extension 21 or the temples 3; when the temples 3 are in the extended state relative to the frame 2, the adjusting member 111 can move relative to the pivot arm 11 in a first direction to adjust the angle of the temples 3 relative to the frame 2 in the extended state. Through this movement, the user can precisely adjust the angle of the temples 3 relative to the frame 2 in the extended state to adapt to different wearing needs and head shape characteristics.
[0069] When the user is ready to wear the smart glasses, they hold the ends of the temples 3 with both hands and gently pull the temples 3 outward. As the temples 3 unfold, the pivot arm 11 begins to rotate relative to the pivot seat 12. At this time, the movable block 1211 in the elastic component 121 moves in the guide hole 1221, and the elastic element 1213 is gradually stretched or compressed, generating a corresponding elastic force.
[0070] Once the temple 3 is extended to a certain angle, the user can further fine-tune the opening angle of the temple 3 using the adjusting piece 111, according to their head shape and wearing habits. Specifically, this is done by rotating the adjusting nut, causing it to move along the thread on the protrusion 112 of the pivot arm 11. As the adjusting nut rotates, its protrusion on the pivot arm 11 changes, thereby changing the angle of the pivot arm 11 relative to the pivot seat 12, ultimately achieving precise adjustment of the angle between the temple 3 and the frame 2.
[0071] During adjustment, users can try different opening angles until they find the most comfortable position that best fits their head shape. Because the minute displacement of the adjustment piece 111 can be amplified to the temple 3 through leverage, users can make very fine adjustments to ensure that the temple 3 fits evenly on both sides of the head, providing stable support.
[0072] When the user needs to remove the smart glasses, they hold the ends of the temples 3 with both hands and gently push them inward. As the temples 3 close, the pivot arm 11 rotates again relative to the pivot seat 12, and the movable block 1211 in the elastic component 121 moves in the opposite direction in the guide hole 1221, and the elastic element 1213 gradually returns to its initial state. After the temples 3 are fully closed, they fit snugly against the frame 2, making it convenient for the user to store them in an eyeglass case or other container.
[0073] The wearable device provided in this application includes a pivot seat 12 and a pivot arm 11. One side of the pivot seat 12 is rotatably connected to the connecting portion 113 of the pivot arm 11. An elastic component 121 is provided on the other side of the pivot seat 12. An adjusting member 111 is provided on one side of the main body 110 of the pivot arm 11. When the pivot arm 11 is in the extended state relative to the pivot seat 12, one end of the elastic component 121 abuts against the pivot seat 12, and the other end abuts against the adjusting member 111. In use, by controlling the distance the adjusting member 111 moves in the first direction of the pivot arm 11, the relative rotation of the pivot seat 12 and the pivot arm 11 can be dynamically adjusted using the elastic component 121 and the adjusting member 11. This adjusts the clamping force of the entire wearable device, ensuring a good fit while avoiding excessive tightness and discomfort for users with different head sizes, thus achieving personalized and comfortable wearing.
[0074] like Figures 1 to 6 As shown, the pivot arm 11 has three fixing nut holes 128, which are symmetrically fastened. This symmetrical layout ensures that the force on the pivot arm 11 is evenly distributed during the fastening process, avoiding deformation or loosening caused by uneven force. Through the three symmetrical fixing nut holes 128, the pivot arm 11 can be firmly connected to the temple 3, ensuring that the temple 3 will not loosen or fall off during daily use.
[0075] Correspondingly, four fixing nut holes 128 are arranged on the pivot seat 12, which are also fastened symmetrically. The symmetrical distribution of the four holes further enhances the stability of the pivot seat 12, making it more reliable when bearing the rotational stress of the pivot arm 11 and the temple 3. Through the four symmetrical fixing nut holes 128, the pivot seat 12 can be firmly installed on the extension 21 of the frame 2. This connection method not only improves the installation strength of the pivot seat 12, but also effectively disperses stress and reduces the risk of damage caused by excessive local stress.
[0076] In some embodiments, such as Figure 1 and Figure 2 As shown, the wearable device has two temples 3, and the frame 2 has two extensions 21 extending toward each temple 3 respectively. Each temple 3 is connected to its corresponding extension 21 by a connecting structure 1. Each connecting structure 1 includes a pivot seat 12, a pivot arm 11, an elastic component 121, and an adjustment element 111. The adjustment element 111 in each connecting structure 1 allows the user to independently adjust the angle of each temple 3, thereby achieving a more precise and personalized fit. Users can adjust the opening angle of the two temples 3 according to their head shape and wearing habits to achieve optimal wearing comfort.
[0077] When wearing the smart glasses, the user holds the temples 3 on both sides and unfolds them from their folded state. The pivot arm 11 in each connecting structure 1 rotates relative to the pivot seat 12, and the movable block 1211 in the elastic component 121 moves within the guide hole 1221, gradually compressing the elastic element 1213. The user can adjust the angle of each temple 3 individually using the adjusting element 111 to ensure the temples 3 fit evenly against both sides of the head. When storing the smart glasses, the user pushes the temples 3 inwards, the pivot arm 11 rotates again relative to the pivot seat 12, and the elastic component 121 returns to its initial state. Once both temples 3 are fully closed, they are easy for the user to store.
[0078] If needed, the connecting structure 1 can also be provided between only one temple 3 and the extension 21. Although there is only one connecting structure 1, the angle adjustment function of one temple 3 is still retained, and the user can adjust the angle of one temple 3 as needed to obtain a comfortable wearing experience.
[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
