Description

Technical Field

[0001] This utility model relates to the field of smart wearable device technology, specifically to a hinge structure and smart glasses. Background Technology

[0002] As an emerging type of wearable smart device, smart glasses are gradually becoming an important part of people's daily lives, work, and entertainment. When choosing smart glasses, stability and appearance often greatly influence consumers' purchasing desire.

[0003] To enable relative rotation between the temples and the frame of smart glasses, the temples are typically connected to the frame via a hinge structure. However, existing hinge structures are usually single-axis hinges. These single-axis hinges are prone to stress concentration due to single-point force application, resulting in poor stability (torsional resistance and durability). Furthermore, they cannot effectively conceal the internal structure (including internal mechanical structures and components, such as FPC flexible circuit boards), exposing the internal structure and significantly affecting the aesthetics of the hinge structure and the smart glasses. Therefore, improving the stability and aesthetics of the hinge structure and smart glasses is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the above-mentioned defects in the existing technology, this utility model provides a hinge structure and smart glasses. The hinge structure and smart glasses not only improve stability, but also solve the problem of exposed internal structure and improve aesthetics.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A hinge structure includes a first flipping member and a second flipping member, which are connected by two spaced-apart elastic self-resetting connecting components. The first flipping member and the elastic self-resetting connecting components are rotatable relative to each other, and the elastic self-resetting connecting components and the second flipping member are linearly movable relative to each other, so that the first flipping member and the second flipping member can flip relative to each other. The hinge structure also includes a shielding structure, which is disposed in the gap between the two elastic self-resetting connecting components to cooperate with the first flipping member and the second flipping member to shield the internal structure when the first flipping member and the second flipping member flip relative to each other.

[0007] In some technical solutions, the shielding structure includes a shielding groove and a shielding plate. One end of the shielding groove extends into the first flipping member and is rotatably connected to the first flipping member, while the other end extends into the second flipping member. One end of the shielding plate is disposed on the second flipping member, and the other end extends into the first flipping member and together with the shielding groove, forms a passageway.

[0008] In some technical solutions, the first flipping component is provided with a first blocking engagement structure that cooperates with the blocking plate and a second blocking engagement structure that cooperates with the blocking groove.

[0009] In some technical solutions, the first shielding structure includes a first plane, a second plane, and a first arc surface. The end face of the first flipping member facing the second flipping member is the first plane. The outer surface of the shielding plate is the third plane, and the wall surface parallel to the third plane is the second plane. The first plane and the second plane are perpendicular to each other, and the first arc surface connects the first plane and the second plane. The end of the shielding plate is wedge-shaped, and its end face is the second arc surface. When the first flipping member is flipped inward by 90° relative to the second flipping member, the first plane and the third plane are in the same plane, and the second plane is in line contact with the second arc surface. When the first flipping member is flipped outward by an angle β relative to the second flipping member, the angle β is less than 90°, and the first arc surface is in line contact with the third plane.

[0010] In some technical solutions, the shielding groove includes a groove panel and groove side plates disposed on opposite sides of the groove panel. The two groove side plates are rotatably connected to the first flipping member, and the shielding plate is mounted on the two groove side plates. The groove panel includes a first step portion and a second step portion disposed in parallel, and a connecting portion perpendicularly connected between the first step portion and the second step portion. The first flipping member is provided with a flipping avoidance opening for avoiding the first step portion, and the first step portion is located within the flipping avoidance opening. The second step portion is located within the second flipping member.

[0011] In some technical solutions, a first wedge-shaped shielding part is provided at the end of the first step portion, and a second wedge-shaped shielding part is provided on the side wall of the flip-out clearance corresponding to the first wedge-shaped shielding part. The first wedge-shaped shielding part and the second wedge-shaped shielding part are stacked, and the first wedge-shaped shielding part is located inside the second wedge-shaped shielding part. The second wedge-shaped shielding part is the second shielding mating structure.

[0012] In some technical solutions, the end face of the first wedge-shaped blocking part is a third arc surface, the end face of the second wedge-shaped blocking part is a fourth plane, and the outer plate surface of the first step part is a fifth plane. When the first flipping member is flipped inward by 90° relative to the second flipping member, the fourth plane contacts the fifth plane. When the first flipping member is flipped outward by the β angle relative to the second flipping member, the fourth plane contacts the third arc surface.

[0013] In some technical solutions, the elastic self-resetting connection assembly includes a connector, an elastic element, and a stop. The second flipping element is provided with a mounting through hole. One end of the connector is rotatably connected to the first flipping element, and the other end of the connector passes through the mounting through hole and is connected to the stop. The elastic element is disposed between the stop and the second flipping element.

[0014] In some technical solutions, the first flipping component includes a first flipping seat and a first housing sleeved on the first flipping seat, and the second flipping component includes a second flipping seat and a second housing sleeved on the second flipping seat. The first flipping seat is provided with a first mounting groove, and the second flipping seat is provided with a second mounting groove. The first mounting groove and the second mounting groove are connected to form the interval. Both of the elastic self-resetting connection components are connected between the first flipping seat and the second flipping seat and are symmetrically arranged on both sides of the interval.

[0015] A smart pair of glasses includes a frame and temples, and also includes a hinge structure as described in any of the above technical solutions, wherein the hinge structure is connected between the frame and the temples.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] The hinge structure provided by this utility model forms a symmetrical support structure through two spaced-apart elastic self-resetting connecting components. During the relative flipping process of the first and second flipping components, the load is evenly distributed, avoiding the stress concentration problem caused by single-point force in traditional single-axis hinges, significantly improving torsional resistance and durability. Through a composite motion design of "rotation + linear movement," the first and second flipping components can flexibly adjust the flipping angle and compensate for the displacement difference generated during flipping through linear movement, reducing mechanical interference and wear. The inclusion of a shielding structure dynamically shields the internal structure, preventing exposure and improving the overall aesthetics of the hinge structure. It also prevents dust from entering the hinge structure, protecting the internal structure and extending its service life. In summary, the hinge structure of this utility model improves stability, solves the problem of exposed internal structure, and enhances aesthetics.

[0018] The smart glasses provided by this utility model, by including the hinge structure described in any of the above technical solutions, also improve stability, solve the problem of exposed internal structure, and enhance aesthetics. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0032] like Figures 1 to 11 The illustration discloses an embodiment of the hinge structure of this utility model. The hinge structure includes a first flipping member 1 and a second flipping member 2. The first flipping member 1 and the second flipping member 2 are connected by two spaced elastic self-resetting connecting components 3. The first flipping member 1 and the elastic self-resetting connecting components 3 can rotate relative to each other, and the elastic self-resetting connecting components 3 and the second flipping member 2 can move linearly relative to each other, so that the first flipping member 1 and the second flipping member 2 can flip relative to each other. The hinge structure also includes a blocking structure 4, which is disposed in the gap between the two elastic self-resetting connecting components 3, so as to cooperate with the first flipping member 1 and the second flipping member 2 to block the internal structure when the first flipping member 1 and the second flipping member 2 flip relative to each other.

[0033] This hinge structure forms a symmetrical support structure through two spaced elastic self-resetting connecting components 3. During the relative flipping process of the first flipping component 1 and the second flipping component 2, the load can be evenly distributed, avoiding the stress concentration problem caused by single-point force in traditional single-axis hinges, and significantly improving torsional resistance and durability. Through the composite motion design of "rotation + linear movement", the first flipping component 1 and the second flipping component 2 can not only flexibly adjust the flipping angle, but also compensate for the displacement difference generated during flipping through linear movement, reducing mechanical interference and wear. By setting the shielding structure 4, the internal structure is dynamically shielded, which not only prevents the internal structure from being exposed, improving the overall aesthetics of the hinge structure, but also prevents dust from entering the hinge structure, protecting the internal structure and extending the service life of the hinge structure.

[0034] In some embodiments, the shielding structure 4 includes a shielding groove 42 and a shielding plate 41. One end of the shielding groove 42 extends into and is rotatably connected to the first flipping member 1, and the other end extends into the second flipping member 2. One end of the shielding plate 41 is disposed on the second flipping member 2, and the other end extends into the first flipping member 1 and together with the shielding groove 42 forms a passageway. By rotatably connecting the shielding groove 42 to the first flipping member 1, relative flipping of the first flipping member 1 and the shielding groove 42 is achieved. By extending the shielding groove 42 into the second flipping member 2, relative sliding of the shielding groove 42 and the second flipping member 2 is achieved. By disposing of one end of the shielding plate 41 on the second flipping member 2 and extending the other end into the first flipping member 1 and together with the shielding groove 42 forming a passageway, not only is the internal structure shielded, but the passageway always provides a protective channel for the internal structure during the relative flipping of the first flipping member 1 and the second flipping member 2, avoiding compression or wear.

[0035] In some embodiments, the first flipping member 1 is provided with a first blocking engagement structure that cooperates with the blocking plate 41 and a second blocking engagement structure that cooperates with the blocking groove 42. By providing the first blocking engagement structure that cooperates with the blocking plate 41 and the second blocking engagement structure that cooperates with the blocking groove 42 on the first flipping member 1, the dynamic blocking effect of the hinge structure during movement is further improved, ensuring that the hinge structure effectively blocks at different flipping angles without gaps.

[0036] In some embodiments, the first shielding mating structure includes a first plane 110, a second plane 111, and a first arc surface 112. The end face of the first flipping member 1 facing the second flipping member 2 is the first plane 110. The outer plate surface of the shielding plate 41 is the third plane 410. The wall surface of the gap between the two elastic self-resetting connecting components 3, which is parallel to the third plane 410, is the second plane 111. The first plane 110 and the second plane 111 are perpendicular to each other. The first arc surface 112 connects the first plane 110 and the second plane 111. The end of the shielding plate 41 is wedge-shaped and its end face is the second arc surface 411. When the first flipping member 1 is flipped inward by 90° relative to the second flipping member 2, the first plane 110 and the third plane 410 are in the same plane, and the second plane 111 and the second arc surface 411 are in line contact. When the first flipping member 1 is flipped outward by a β angle relative to the second flipping member 2, the β angle is less than 90°, and the first arc surface 112 is in line contact with the third plane 410. Different line contact and surface contact correspond to different flip angles. This design makes the contact between the various blocking parts of the hinge structure smoother during the flipping process, reducing wear, while maintaining aesthetics and optimizing the blocking effect.

[0037] The angle β shown in the figure is between 10° and 30°. In some embodiments, under the limiting action of the second flipping member 2, the angle β is 15°. The specific angle can be set according to actual needs and is not limited here.

[0038] In some embodiments, the shielding groove 42 includes a groove panel 421 and groove side plates 422 disposed on opposite sides of the groove panel 421. The two groove side plates 422 are rotatably connected to the first flipping member 1 via a pivot 43. The shielding plate 41 is mounted on the two groove side plates 422. The groove panel 421 includes a first step portion 4211 and a second step portion 4213 disposed in parallel, and a connecting portion 4212 vertically connected between the first step portion 4211 and the second step portion 4213. The first flipping member 1 is provided with a flipping avoidance opening 121 for avoiding the first step portion 4211. The first step portion 4211 is located inside the flipping avoidance opening 121. The second step portion 4213 is located inside the second flipping member 2. By designing the groove panel 421 as a stepped structure, and setting a flip clearance opening 121 on the first flip member 1, and placing the first stepped portion 4211 of the groove panel 421 inside the flip clearance opening 121, the hinge structure is not only more compact and lightweight, but also allows for a larger flip angle, avoiding the impact on wearing comfort due to the hinge structure being too bulky.

[0039] In some embodiments, a first wedge-shaped shielding portion 4214 is provided at the end of the first step portion 4211, and a second wedge-shaped shielding portion 122 is provided on the side wall of the flip-out clearance opening 121 corresponding to the first wedge-shaped shielding portion 4214. The first wedge-shaped shielding portion 4214 and the second wedge-shaped shielding portion 122 are stacked, with the first wedge-shaped shielding portion 4214 located inside the second wedge-shaped shielding portion 122. The second wedge-shaped shielding portion 122 is a second shielding mating structure. By stacking the first wedge-shaped shielding portion 4214 and the second wedge-shaped shielding portion 122, on the one hand, better shielding can be provided for the hinge structure when the hinge structure is at an extreme flip angle; on the other hand, dust can be further effectively prevented from entering the interior of the hinge structure, thereby improving the durability of the hinge structure.

[0040] In some embodiments, the end face of the first wedge-shaped blocking portion 4214 is a third arc surface 42140, the end face of the second wedge-shaped blocking portion 122 is a fourth plane 1220, and the outer plate surface of the first stepped portion 4211 is a fifth plane 42110. When the first flipping member 1 is flipped inward by 90° relative to the second flipping member 2, the fourth plane 1220 and the fifth plane 42110 are in surface contact; when the first flipping member 1 is flipped outward by an angle β relative to the second flipping member 2, the fourth plane 1220 and the third arc surface 42140 are in line contact. Different line contact and surface contact correspond to different flipping angles. This arrangement makes the contact between the blocking components smoother during the flipping process of the hinge structure, reduces wear, maintains aesthetics, and optimizes the blocking effect.

[0041] In some embodiments, the elastic self-resetting connection assembly 3 includes a connector 31, an elastic element 32, and a stop 33. The second flip member 2 has a mounting through hole 210. One end of the connector 31 is rotatably connected to the first flip member 1, and the other end of the connector 31 passes through the mounting through hole 210 and connects to the stop 33. The elastic element 32 is disposed between the stop 33 and the second flip member 2, and is preferably a spring. Specifically, the connectors 31 of the two elastic self-resetting connection assemblies 3 are respectively connected to corresponding rotating shafts 43. This arrangement simplifies the assembly process while providing a reliable elastic reset function, ensuring that the hinge structure opens and closes consistently each time.

[0042] In some embodiments, the first flipping component 1 includes a first flipping seat 11 and a first housing 12 sleeved on the first flipping seat 11, and the second flipping component 2 includes a second flipping seat 21 and a second housing 22 sleeved on the second flipping seat 21. The first flipping seat 11 and the first housing 12, and the second flipping seat 21 and the second housing 22 are all connected by connecting pins 5. The first flipping seat 11 is provided with a first mounting groove 113, and the second flipping seat 21 is provided with a second mounting groove 211. The first mounting groove 113 and the second mounting groove 211 are connected to form the interval. Two elastic self-resetting connecting components 3 are connected between the first flipping seat 11 and the second flipping seat 21 and are symmetrically arranged on both sides of the interval. By decomposing the first flipping component 1 into the first flipping seat 11 and the first housing 12, and the second flipping component 2 into the second flipping seat 21 and the second housing 22, not only is the installation and maintenance of the internal structure of the hinge structure convenient, but this modular design also facilitates production and maintenance, and reduces production costs.

[0043] In some embodiments, the slot of the first mounting groove 113 and the notch on the first housing 12 together form a flip clearance opening 121, and the second wedge-shaped shielding part 122 is disposed on the first housing 12; the shielding plate 41 is disposed on the second housing 22 and is integrally disposed with the second housing 22. Of course, the shielding plate 41 can also be disposed on the second flipping seat 21, which is not limited here.

[0044] Based on the hinge structures provided in the above embodiments, this utility model also provides smart glasses, which include a frame and temples, and further include the hinge structure described in any one of the above embodiments, the hinge structure being connected between the frame and the temples. Using the above hinge structure not only satisfies the rotational connection requirements of the frame and temples, but also meets the requirements of smart glasses for a lightweight, durable, and aesthetically pleasing hinge structure, significantly improving the user experience.

[0045] In some embodiments, the first housing 12 is connected to the temple and the second housing 22 is connected to the frame. Of course, the first housing 12 can also be integrally formed with the temple and the second housing 22 can be integrally formed with the frame. The specific choice depends on the actual needs and is not limited here.

[0046] The foregoing has described in detail several embodiments of the hinge structure and smart glasses of this utility model. Many other embodiments are also described, but will not be elaborated upon here. The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.

[0047] In summary, the hinge structure and smart glasses of this invention improve stability, solve the problem of exposed internal structure, and enhance aesthetics.

[0048] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
