Description

Technical Field

[0001] This application belongs to the field of mechanical parts technology, and particularly relates to a rotating connection structure and eyeglasses. Background Technology

[0002] Smart glasses are wearable devices that integrate multiple functions. They not only have the vision correction function of traditional glasses, but also incorporate high-tech elements such as built-in operating system, Internet connection, multimedia playback, and voice control.

[0003] In related technologies, the frames and temples of smart glasses are usually connected and rotated by traditional pivots or fastening screws. However, this rotating connection method makes it difficult to control the tightening force of traditional pivots or fastening screws during assembly, which can easily lead to poor consistency between different eyeglass frames. Utility Model Content

[0004] The purpose of this application is to at least solve the problem of poor consistency in rotary connection structures. This purpose is achieved through the following technical solution: The first aspect of this application proposes a rotating connection structure, comprising: The first support includes a first main body and a first protruding end and a second protruding end disposed on the first main body and disposed opposite to each other. A first receiving space is formed between the first protruding end and the second protruding end. A first groove is formed on the surface of the first protruding end facing the first receiving space, and a second groove is formed on the surface of the second protruding end facing the first receiving space. The second bracket includes a second main body and a third protruding end and a fourth protruding end disposed on and opposite to the second main body. The third protruding end and the fourth protruding end are located within the first accommodating space. The third protruding end includes a first through hole disposed opposite to the first groove, and the fourth protruding end includes a second through hole disposed opposite to the second groove. The rotating shaft assembly includes a first insertion part, a second insertion part, and an elastic member. The first insertion part is sequentially inserted into the first through hole and the first groove, and the second insertion part is sequentially inserted into the second through hole and the second groove. The two ends of the elastic member along its own extension and contraction direction respectively abut against the side of the first insertion part away from the first groove and the side of the second insertion part away from the second groove, and the elastic member is in a compressed state.

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0020] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0021] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] In related technologies, rotating connection structures include fastening screws or pivots. Because the tightening force of fastening screws and pivots during assembly is difficult to control precisely, consistency between different rotating connection structures is hard to maintain. Furthermore, fastening screws and pivots require specialized tooling for assembly, resulting in high costs. This application provides a rotating connection structure for eyeglasses that eliminates fastening screws and pivots, employing a pivot assembly with better assembly consistency. This improves the consistency of the pivot connection structure, simplifies assembly, and reduces costs.

[0024] like Figure 1 As shown, according to an embodiment of this application, a rotating connection structure 1 is proposed, which includes a first bracket 11, a second bracket 12, and a rotating shaft assembly 13. Figure 2 and Figure 3 As shown, the first support 11 includes a first main body 111 and a first protruding end 112 and a second protruding end 113 disposed on the first main body 111 and disposed opposite to each other, forming a first receiving space Q between the first protruding end 112 and the second protruding end 113. Figure 4 and Figure 5 As shown, a first groove 1121 is formed on the surface of the first protruding end 112 facing the first receiving space Q, and a second groove 1131 is formed on the surface of the second protruding end 113 facing the first receiving space Q. The second bracket 12 includes a second main body 121 and a third protruding end 122 and a fourth protruding end 123 disposed on the second main body 121 and disposed opposite to each other. The third protruding end 122 and the fourth protruding end 123 are located within the first receiving space Q. The third protruding end 122 includes a first through hole 1221 disposed opposite to the first groove 1121, and the fourth protruding end 123 includes a second through hole 1231 disposed opposite to the second groove 1131. Figures 4 to 7 As shown, the rotating shaft assembly 13 includes a first insertion part 131, a second insertion part 132, and an elastic member 133. The first insertion part 131 is sequentially inserted into the first through hole 1221 and the first groove 1121. The second insertion part 132 is sequentially inserted into the second through hole 1231 and the second groove 1131. The two ends of the elastic member 133 along its own extension and contraction direction respectively abut against the side of the first insertion part 131 away from the first groove 1121 and the side of the second insertion part 132 away from the second groove 1131, and the elastic member 133 is in a compressed state.

[0025] In the rotating connection structure 1 provided in this application, the first bracket 11 and the second bracket 12 are connected by a rotating shaft assembly 13. The first protruding end 112 and the second protruding end 113 of the first bracket 11 are both fixed to the first main body 111, so that the positions of the first protruding end 112 and the second protruding end 113 are relatively fixed. The third protruding end 122 of the second bracket 12 is rotatably connected to the first protruding end 112 through the first insertion part 131 in the rotating shaft assembly 13. The fourth protruding end 123 of the second bracket 12 is rotatably connected to the second protruding end 113 through the second insertion part 132 in the rotating shaft assembly 13. The first insertion part 131 and the second insertion part 132 are connected by an elastic member 133, and the elastic member 133 is under pressure. In the retracted state, one end of the first insertion part 131 abuts against the bottom wall of the first groove 1121, and the other end contacts the elastic member 133. Under the pressure of the elastic member 133, the position of the first insertion part 131 along its own axial direction is relatively fixed. One end of the second insertion part 132 abuts against the bottom wall of the second groove 1131, and the other end contacts the elastic member 133. The elastic member 133 provides pressure to the first insertion part 131 towards the bottom wall of the first groove 1121 and to the second insertion part 132 towards the bottom wall of the second groove 1131. Under the pressure of the elastic member 133, the position of the second insertion part 132 along its own axial direction is relatively fixed, thereby realizing the rotatable connection between the first bracket 11 and the second bracket 12. This rotatable connection structure 1 has a simple structure and a simple assembly method. Moreover, the rotation effect of the rotatable connection structure 1 depends on the specifications of the elastic member 133. Since the consistency of different elastic members 133 is well controlled, the consistency of different rotatable connection structures 1 can be improved.

[0026] The first bracket 11 and the second bracket 12 of the rotary connection structure 1 can be connected to different components respectively, so as to realize the rotary connection between different components through the rotary connection structure 1.

[0027] In the above embodiments, such as Figure 7As shown, the outer diameter of the end of the first insertion portion 131 away from the first groove 1121 is larger than the diameter of the first through hole 1221, so as to limit the third protruding end 122 between the first protruding end 112 and the end of the first insertion portion 131 away from the first groove 1121. The outer diameter of the end of the second insertion portion 132 away from the second groove 1131 is larger than the diameter of the second through hole 1231, so as to limit the fourth protruding end 123 between the second protruding end 113 and the end of the second insertion portion 132 away from the second groove 1131. Because the elastic element 133 is in a contracted state, it provides pressure to the first insertion portion 131 and the second insertion portion 132 located on both sides of it, so that the first protruding end 112, the third protruding end 122, and the end of the first insertion portion 131 away from the first groove 1121 are in a tight fit, and the second protruding end 113, the fourth protruding end 123, and the end of the second insertion portion 132 away from the second groove 1131 are in a tight fit, thereby making the first bracket 11 and the second bracket 12 have a damping effect during relative rotation, and can be suspended at any angle during rotation.

[0028] In the above embodiments, the elasticity of the elastic element 133 can compensate for the wear caused by the rotational connection structure 1 during use. After wear, the size of the first accommodating space Q along the arrangement direction of the first protruding end 112 and the second protruding end 113 increases. The elastic element 133 can compensate for this through its own elasticity, thereby reducing the impact of wear during use on the rotational connection effect, ensuring the reliability of the hovering function, and enhancing the user experience.

[0029] In the above embodiments, in the rotating connection structure 1, since the first groove 1121 and the second groove 1131 are arranged opposite to each other, the rotating shaft assembly 13 is confined inside the first accommodating space Q. The rotating shaft assembly 13 cannot be seen from the outside of the rotating connection structure 1, thereby improving the aesthetics, preventing disassembly, and making it easy to clean.

[0030] In one feasible implementation, such as Figure 3 , Figure 6 and Figure 7 As shown, the first main body 111 is provided with a snap-fit ​​groove 1111, and the elastic member 133 is snap-fitted into the snap-fit ​​groove 1111.

[0031] In the above embodiment, the snap-fit ​​groove 1111 and the first protruding end 112 are located on the same surface of the first main body portion 111.

[0032] The snap-fit ​​groove 1111 engages with the elastic element 133, which can further enhance the fixing strength of the elastic element 133 and improve the reliability of the rotating connection structure 1.

[0033] In one feasible implementation, such as Figure 7As shown, the elastic member 133 includes a connecting portion 1331 and a plurality of elastic portions 1332. The plurality of elastic portions 1332 are arranged along a first direction x. The connecting portion 1331 is located between two adjacent elastic portions 1332. The elastic member 133 can extend and retract along the first direction x through the elastic portions 1332. The two elastic portions 1332 located at both ends of the elastic member 133 along the first direction x abut against the first insertion portion 131 and the second insertion portion 132, respectively. The connecting portion 1331 engages with the snap-fit ​​groove 1111. The first direction x is the arrangement direction of the first insertion portion 131 and the second insertion portion 132.

[0034] In the above embodiments, the elastic member 133 includes a connecting portion 1331 and a plurality of elastic portions 1332. The connecting portion 1331 is disposed between the elastic portions 1332 and is used to connect adjacent elastic portions 1332. The connecting portion 1331 is engaged and fixed with the snap-fit ​​groove 1111 to further fix the elastic member 133.

[0035] Multiple elastic portions 1332 are arranged along the first direction x and can extend and retract along the first direction x, so that the multiple elastic portions 1332 can be compressed and disposed between the first insertion portion 131 and the second insertion portion 132 to provide pressure to the first insertion portion 131 and the second insertion portion 132.

[0036] In one feasible embodiment, the elastic member 133 further includes an elastic arm 1333, which includes a first end and a second end disposed opposite to each other. The first end of the elastic arm 1333 is fixed to one of the connecting portion 1331 and the elastic portion 1332. The elastic arm 1333 is configured such that the elastic force between it and the connecting portion 1331 changes with the positional relationship between the second end of the elastic arm 1333 and the connecting portion 1331.

[0037] The second end of the elastic arm 1333 can rotate about the first end towards the connecting part 1331 after being subjected to pressure, thereby increasing the elastic force between the elastic arm 1333 and the connecting part 1331; alternatively, it can rotate about the first end away from the connecting part 1331, thereby decreasing the elastic force between the elastic arm 1333 and the connecting part 1331. In other words, the second end of the elastic arm 1333 is configured such that its relative position to the connecting part 1331 can change under the action of an external force, and the elastic force between the elastic arm 1333 and the connecting part 1331 can also change under the action of an external force.

[0038] In one feasible implementation, such as Figure 7 , Figure 8 and Figure 9 As shown, the first bracket 11 also includes an abutment groove 114, which is located on the side of the first main body 111 facing the first extended end 112, and the elastic arm 1333 abuts and engages with the abutment groove 114.

[0039] In the above embodiment, by providing an abutment groove 114 on the first bracket 11, the elastic arm 1333 can be limited. Simultaneously, the engagement of the connecting portion 1331 with the snap-fit ​​groove 1111 and the abutment engagement of the elastic arm 1333 with the abutment groove 114 prevent the elastic member 1333 from rotating around the first direction x. Specifically, when the elastic member 133 engages with the first insertion portion 131 and the second insertion portion 132, there is an elastic force between the elastic arm 1333 and the connecting portion 1331 that moves away from each other.

[0040] In one feasible implementation, such as Figure 4 and Figure 5 As shown, the first main body 111 includes a first side and a second side disposed opposite to each other. A first protruding end 112 and a second protruding end 113 are located on the first side. A button hole 1112 is formed on the first main body 111, and the button hole 1112 penetrates the first main body 111 along the arrangement direction of the first side and the second side. The first bracket 11 also includes a button 115, one end of which has an abutting groove 114, and the other end of which passes through the button hole 1112.

[0041] In the above embodiments, the first support 11 and the second support 12 may have three working positions, including a normal working position, an outward turning working position, and an inward turning working position. The first support 11 and the second support 12 can rotate relative to each other within a preset angle range.

[0042] like Figure 10 As shown, the normal working position refers to the following: the first support 11 is located on one side of the second support 12, the surface of the first main body 111 facing the first side is parallel to the surface of the second main body 121 facing the first support 11, and the pressing direction of the button 115 is perpendicular to the surface of the second main body 121 facing the first support 11. At this time, the button 115 can contact or be spaced at a preset distance from the surface of the second main body 121 facing the first support 11.

[0043] like Figure 11 As shown, the outward turning station refers to a situation where the first bracket 11 is located on one side of the second bracket 12, the plane containing the surface of the first main body 111 facing the first side intersects the plane containing the surface of the second main body 121 facing the first bracket 11, and the pressing direction of the button 115 intersects with but is not perpendicular to the surface of the second main body 121 facing the first bracket 11. At this time, the button 115 abuts against the surface of the second main body 121 facing the first bracket 11. At this time, the rotation of the first bracket 11 towards the second bracket 12 is restricted.

[0044] like Figure 12As shown, the inward turning station refers to a situation where the first bracket 11 is located on one side of the second bracket 12, the plane containing the surface of the first main body 111 facing the first side intersects the plane containing the surface of the second main body 121 facing the first bracket 11, and the pressing direction of the button 115 intersects with but is not perpendicular to the surface of the second main body 121 facing the first bracket 11. At this time, the button 115 is not in contact with the surface of the second main body 121 facing the first bracket 11.

[0045] By setting button 115, the first main body 111 can be automatically returned to its original position relative to the second main body 121, that is, automatically returned from the outward turning position to the normal position. Specifically, under the action of external force, button 115 can pass through button hole 1112 and abut against the second main body 121. Since the second end of elastic arm 1333 can rotate towards the connecting part 1331 with the first end as the center after being pressed, the elastic force between elastic arm 1333 and connecting part 1331 increases. Therefore, after the second main body 121 abuts against button 115, the elastic force between elastic arm 1333 and connecting part 1331 increases. After the external force is removed, under the action of elastic force, the second end of elastic arm 1333 moves away from connecting part 1331, thereby achieving automatic return.

[0046] Specifically, the surface of the first main body 111 facing the first side and the surface facing the second side can be arranged to intersect. Thus, in the normal working position, the plane where the surface of the first main body 111 facing the second side is located intersects the plane where the surface of the second main body 121 facing the first support 11 is located. Moreover, the distance between the end of the surface of the first main body 111 facing the second side near the pivot and the surface of the second main body 121 facing the first support 11 is greater than the distance between the end away from the pivot and the surface of the second main body 121 facing the first support 11, thereby making the button 115 more effective.

[0047] In another feasible embodiment, the abutment groove 114 is formed on the surface of the first main body portion 111 facing the first side. In this embodiment, the button 115 is not provided. The position of the elastic member 133 is only auxiliaryly defined by the elastic arm 1333.

[0048] In one feasible implementation, such as Figure 7 As shown, the elastic element 133 includes a double torsion spring, the elastic part 1332 includes a spring 1334, the two elastic parts 1332 have the same axial direction and opposite winding direction, and the connecting part 1331 and the elastic arm 1333 are arranged opposite each other along the radial direction of the elastic part 1332.

[0049] In the above embodiment, the elastic member 133 includes two elastic parts 1332, and each elastic part 1332 includes a spring 1334. The axial directions of the two springs 1334 are both parallel to the first direction x, and the winding directions are opposite. That is, when viewed from one end of the elastic member 133, one spring 1334 is wound clockwise and the other spring 1334 is wound counterclockwise.

[0050] The use of double torsion springs allows the button 115 to be reset under torque and the first plug-in part 131 and the second plug-in part 132 to be fixed under elastic force.

[0051] In one feasible implementation, such as Figure 5 As shown, the first insertion part 131 is provided with a first limiting protrusion 1311 on the side away from the first groove 1121, and the second insertion part 132 is provided with a second limiting protrusion 1321 on the side away from the second groove 1131. The two elastic parts 1332 are respectively sleeved on the first limiting protrusion 1311 and the second limiting protrusion 1321.

[0052] The first limiting protrusion 1311 and the second limiting protrusion 1321 can respectively limit the two elastic parts 1332 in the radial direction, and the first limiting protrusion 1311 and the second limiting protrusion 1321 can work together to limit the elastic member 133 in the first direction x.

[0053] Specifically, when the elastic part 1332 includes springs 1334, the two springs 1334 are respectively sleeved on the first limiting protrusion 1311 and the second limiting protrusion 1321.

[0054] In one feasible implementation, such as Figure 13 As shown, the elastic element 133 includes a spring sheet, and the elastic portion 1332 includes a first spring sheet portion 1335. The first spring sheet portion 1335 includes a first end and a second end disposed opposite to each other. The first end of the first spring sheet portion 1335 is fixed to the connecting portion 1331. The elastic force between the first spring sheet portion 1335 and the connecting portion 1331 is configured to change with the change in the positional relationship between the second end of the first spring sheet portion 1335 and the connecting portion 1331.

[0055] In the above embodiment, there can be two first spring sheet portions 1335. The two first spring sheet portions 1335 are respectively fixed to both ends of the connecting portion 1331 along the first direction x. The second end of the first spring sheet portion 1335 can move towards or away from the connecting portion 1331 with the first end as a base point after being subjected to pressure. When moving towards the connecting portion 1331, the elastic force between the first spring sheet portion 1335 and the connecting portion 1331 increases; when rotating away from the connecting portion 1331, the elastic force between the first spring sheet portion 1335 and the connecting portion 1331 decreases. That is, the second end of the first spring sheet portion 1335 is configured such that its relative position with the connecting portion 1331 can change under the action of an external force, and the elastic force between the first spring sheet portion 1335 and the connecting portion 1331 can change under the action of an external force.

[0056] Specifically, the first spring fragment portion 1335 may include a bent portion.

[0057] The spring also includes a second spring portion 1336. The first end of the second spring portion 1336 is fixed to the connecting portion 1331. The second end of the second spring portion 1336 is configured such that the elastic force between the second end and the connecting portion 1331 changes with the positional relationship between the second end and the connecting portion 1331. There can be two second spring portions 1336, both of which are fixed to the connecting portion 1331. The second end of the second spring portion 1336 can move towards or away from the connecting portion 1331 with the first end as the base point after being subjected to pressure. When moving towards the connecting portion 1331, the elastic force between the second spring portion 1336 and the connecting portion 1331 increases; when rotating away from the connecting portion 1331, the elastic force between the second spring portion 1336 and the connecting portion 1331 decreases. That is, the second end of the second spring piece 1336 is configured such that its relative position with the connecting part 1331 can change under the action of external force, and the elastic force between the second spring piece 1336 and the connecting part 1331 can change under the action of external force.

[0058] Specifically, the second end of the second spring piece 1336 abuts against the abutment groove 114.

[0059] In one feasible implementation, such as Figure 5 As shown, the first insertion part 131 is provided with a first limiting groove 1312 on the side away from the first groove 1121, and the second insertion part 132 is provided with a second limiting groove 1322 on the side away from the second groove 1131. The two elastic parts 1332 are respectively engaged with the first limiting groove 1312 and the second limiting groove 1322.

[0060] When the elastic part 1332 includes a spring 1334, the first limiting groove 1312 and the second limiting groove 1322 can be circular, and the end of the spring 1334 is limited to the first limiting groove 1312 and the second limiting groove 1322.

[0061] When the elastic part 1332 includes the first spring piece portion 1335, the first limiting groove 1312 and the second limiting groove 1322 can be shapes adapted to the second end of the first spring piece portion 1335, specifically, they can be rectangles or rounded rectangles, etc.

[0062] In one feasible implementation, such as Figure 14 and Figure 15 As shown, the rotating connection structure 1 also includes a decorative element 14, which is disposed within the first receiving space Q, such as... Figure 16 As shown, the decorative part 14 has a cylindrical structure. The axial direction of the cylindrical structure is parallel to the arrangement direction of the first through hole 1221 and the second through hole 1231. One end of the cylindrical structure is fixed to the end of the first insertion part 131 away from the first groove 1121, and the other end is fixed to the end of the second insertion part 132 away from the second groove 1131. Two spaced openings 141 are provided on the side wall of the decorative part 14.

[0063] In the above embodiments, such as Figure 16 As shown, the end of the cylindrical structure can be an annular structure with an opening 142. The first insertion part 131 / second insertion part 132 enters the annular structure through the opening 142. The opening 142 has a certain elasticity. When the first insertion part 131 / second insertion part 132 is inserted into the annular structure, the opening 142 shrinks due to its own elasticity to achieve the engagement of the first insertion part 131 / second insertion part 132. The decorative part 14 can be fixed relative to the first insertion part 131 and the second insertion part 132, and rotates synchronously with the rotation of the first insertion part 131 and the second insertion part 132.

[0064] Specifically, such as Figure 17 and Figure 18 As shown, the decorative element 14 can be used to shield the first receiving space Q to prevent the pivot assembly 13 from being seen from the outside. The decorative element 14 can also shield components inside itself.

[0065] Specifically, such as Figure 17 and Figure 18 As shown, the decorative component 14 has two spaced openings 141 on its side wall, which can be used to block the wiring 16 passing through the first receiving space Q. The two ends of the wiring 16 pass through the openings 141 respectively. One end of the wiring 16 extends toward the first bracket 11 and the other end extends toward the second bracket 12, thereby realizing the electrical connection between the structure connected to the first bracket 11 and the structure connected to the second bracket 12.

[0066] This application also provides a pair of glasses 15, such as Figure 19 As shown, it includes any one of the rotating connection structures 1 provided in the above embodiments.

[0067] In the glasses 15, the first bracket 11 is used to connect the temple 151, and the second bracket 12 is used to connect the frame 152, on which the lens is fixed.

[0068] During the wearing process, the temples of the glasses 15 are opened to a certain angle for the user to wear. The temples 151 rotate relative to the frame through the rotating connection structure 1. They can rotate from the inward state to the normal state or the outward state, and can be suspended at any angle in the inward state to adapt to the width of the user's face.

[0069] When rotated to the outward-facing position, a clamping force can be provided via button 115 to prevent it from falling off during wear.

[0070] The glasses 15 have no screw holes or shaft holes on the exterior, making them tamper-proof, aesthetically pleasing, and easy to clean, preventing dust accumulation in areas without screw holes or shaft holes. Furthermore, the rotation is achieved through the shaft assembly 13 in the hinge connection structure, ensuring good consistency, and the structure is simple, easy to assemble, and low in cost.

[0071] It is understood that the rotating connection structure 1 can be applied not only to eyeglasses 15, but also to other components that require a rotating connection. This application does not make any special limitation on this.

[0072] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
