Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of smart glasses, and particularly relates to a rotating shaft mechanism and smart glasses. BACKGROUND

[0002] Smart glasses are intelligent devices integrating technology and fashion, which can provide users with more convenient and efficient life experience by interacting with mobile phones, smart watches and other devices. When a large-head user wears smart glasses, the opening angle of the glasses legs is large, and the smart glasses are easy to fall off.

[0003] At present, in smart glasses, an elastic member is arranged in the frame to adapt to the wearing experience of users with different head circumferences. When users with different head circumferences wear smart glasses, the opening angles of the glasses legs are different. At this time, the glasses legs contact and extrude the elastic member, and the elastic member produces different deformation amounts and provides different forces to the glasses legs. Therefore, for large-head users, the elastic member provides a larger force, and the clamping effect of the glasses legs is more obvious, and the smart glasses are not easy to fall off.

[0004] However, for the above structure, the elastic member is usually silicone, which is easy to be affected by moisture and heat and fail with the passage of time, and has a short service life. CONTENT OF THE UTILITY MODEL

[0054] The embodiments of the present disclosure provide a rotating shaft mechanism, as shown in Figure 1 and Figure 2 The rotating shaft mechanism includes a fixed part 1, an elastic part 2, a sliding part 3, and a rotating part 4.

[0055] The fixed part 1 has a receiving cavity 11 and an opening 12 connected in communication. The elastic part 2 is a spring, the elastic part 2 is located in the receiving cavity 11, and one end of the elastic part 2 is connected to the fixed part 1. The sliding part 3 is in sliding connection with the opening 12 and is connected to the other end of the elastic part 2. The rotating part 4 is located outside the receiving cavity 11 and is in rotational connection with the fixed part 1, and the rotating part 4 can push the sliding part 3 to slide into the receiving cavity 11.

[0056] The rotating shaft mechanism can be applied to smart glasses. In the case where the rotating shaft mechanism is applied to smart glasses, the rotating part 4 is a leg of the smart glasses, and the fixed part 1 is a frame of the smart glasses. For convenience, when the rotating part 4 rotates relative to the fixed part 1, the rotation in which the included angle between the two gradually increases is called forward rotation of the rotating part 4, and the rotation in which the included angle between the two gradually decreases is called reverse rotation of the rotating part 4. That is, as the rotating part 4 rotates forward, the leg of the smart glasses unfolds relative to the frame, and then the user can wear the smart glasses. As the rotating part 4 rotates reversely, the leg of the smart glasses is stored relative to the frame, which is convenient for the user to store the smart glasses.

[0057] With the technical scheme provided by the embodiment of the present disclosure, the rotating shaft mechanism is applied to the smart glasses, the rotating part 4 is rotationally connected with the fixed part 1, the rotating part 4 rotates forward, the rotating part 4 can push the sliding part 3 to slide into the accommodating cavity 11, and the elastic part 2 is elastically deformed. The compressed elastic part 2 can exert a pushing force on the rotating part 4, and the pushing force forms a torque that can drive the rotating part 4 to rotate reversely, thereby improving the clamping effect of the glasses leg on the user's head, so that the smart glasses are not easy to fall off when worn by the user. Since the elastic part 2 is a spring, compared with the technical scheme in the related art in which silica gel is used as the elastic part, the spring is not easy to fail in a hot and humid environment, thereby improving the service life of the rotating shaft mechanism.

[0058] In the following, the structure of the rotating shaft mechanism is introduced in detail with the case that the rotating shaft mechanism is applied to the smart glasses as an example.

[0059] In some possible embodiments, the fixed part 1 includes a body 101 and a rotating shaft 102, the rotating shaft 102 is connected with the body 101, and the rotating part 4 is rotationally connected with the rotating shaft 102.

[0060] Referring to Figure 1 and Figure 2 , the body 101 is a frame of the smart glasses, the two ends of the body 101 are respectively provided with an installation protruding structure 100, the extension directions of the two installation protruding structures 100 are the same, and each installation protruding structure 100 is connected with a rotating part 4. The body 101 can be made of a metal material, such as titanium alloy or stainless steel, of course, the body 101 can also be made of plastic, and the embodiments of the present disclosure do not limit the material of the body 101.

[0061] As shown in Figure 5 , the inner side (i.e., the side close to the nose bridge) of the installation protruding structure 100 is provided with an installation groove 13, the installation groove 13 is a through groove, and the extension direction is parallel to the protruding direction of the installation protruding structure 100. An installation hole is arranged on each of the two groove walls opposite to the installation groove 13, and each installation hole accommodates one end of the rotating shaft 102. The rotating shaft 102 is located in the installation groove 13, and the two ends of the rotating shaft 102 extend into one installation hole respectively. The end of the rotating part 4 close to the installation protruding structure 100 is provided with an installation through hole 400, and the shape and size of the installation through hole 400 are respectively matched with the shape and size of the rotating shaft 102.

[0062] In an example, the rotating part 4 is sleeved on the rotating shaft 102 and fixedly connected with the rotating shaft 102, and the rotating shaft 102 is rotationally connected with the body 101. Alternatively, in the example, the two ends of the rotating shaft 102 are cylindrical structures, and the part of the rotating shaft 102 located in the installation through hole 400 can be a cubic structure, and correspondingly, the installation through hole 400 can be a square through hole. Alternatively, the part of the rotating shaft 102 located in the installation through hole 400 and the installation through hole 400 can be an interference fit.

[0063] In one example, the rotating member 4 is sleeved on the rotating shaft 102, and is rotationally connected with the rotating shaft 102, and the rotating shaft 102 is fixedly connected with the body 101. Alternatively, in this example, the end of the rotating shaft 102 can be in interference fit with the mounting hole on the slot wall of the mounting slot 13. Alternatively, the end of the rotating shaft 102 can be clamped with the mounting hole on the slot wall of the mounting slot 13.

[0064] In some examples, the rotating shaft 102 is detachably connected with the body 101. In this way, the dismounting efficiency of the rotating shaft 102 can be improved, and the rotating shaft 102 can be conveniently replaced later.

[0065] As shown in Figure 5 , the body 101 comprises an outer shell 1011, an inner shell 1012, and a rotating shaft fixing support 1013. The end of the outer shell 1011 has the mounting protruding structure 100 described above, and the inner side of the mounting protruding structure 100 has a slot structure. The rotating shaft fixing support 1013 is fixed in the slot structure of the outer shell 1011, the inner side of the rotating shaft fixing support 1013 has the mounting slot 13, the end of the rotating shaft fixing support 1013 close to the rotating member 4 has the opening 12, and the outer side wall (i.e. the side wall surface away from the nose pad) of the rotating shaft fixing support 1013 and the slot wall of the slot structure of the outer shell 1011 form the accommodating cavity 11.

[0066] Specifically, referring to Figure 5 , the upper slot wall of the mounting slot 13 has a through hole, and the lower slot wall of the mounting slot 13 has a blind hole. In implementation, the end of the rotating member 4 close to the mounting protruding structure 100 can be inserted into the mounting slot 13, and the mounting through hole 400 is aligned with the through hole of the upper slot wall of the mounting slot 13, and then the rotating shaft 102 is sequentially passed through the through hole of the upper slot wall of the mounting slot 13 and the mounting through hole 400 to reach the blind hole of the lower slot wall of the mounting slot 13, and the assembly of the rotating shaft 102 is completed.

[0067] Further, referring to Figure 5 , the inner shell 1012 has an avoidance area 200, and the avoidance area 200 and the mounting slot 13 are respectively matched in shape and size. The side of the inner shell 1012 close to the outer shell 1011 has a buckle 1012a, and the side of the rotating shaft fixing support 1013 close to the inner shell 1012 has a clamping groove 1013a, and the buckle 1012a is clamped with the clamping groove 1013a, so that the outer shell 1011 and the inner shell 1012 are clamped. When the rotating shaft 102 needs to be dismounted, the inner shell 1012 can be dismounted from the clamping groove 1013a, and then the rotating shaft fixing support 1013 is dismounted from the slot structure of the outer shell 1011, so that the rotating shaft 102 can be dismounted from the inside of the mounting slot 13.

[0068] In an example, the end of the rotating member 4 has a protruding structure which is in contact with the bottom of the mounting groove 13 during the rotation of the rotating member 4 relative to the fixed member 1.

[0069] As shown in Figure 6 , the rotating member 4 comprises a first part 41 and a second part 42. The first part 41 is located at the end of the second part 42 and connected with the second part 42. The first part 41 is adapted to the shape and size of the mounting groove 13. The first part 41 has the mounting through hole 400 which is sleeved on the rotating shaft 102 and connected with the rotating shaft 102. Further, the outer wall of the first part 41 has a third protruding structure 411 which is in contact with the bottom of the mounting groove 13. In this way, the third protruding structure 411 can increase the rotation damping between the rotating member 4 and the fixed member 1, and improve the experience of the user wearing the smart glasses.

[0070] Optionally, as shown in Figure 6 , the third protruding structure 411 can have a strip structure, and the contact type between the third protruding structure 411 and the bottom of the mounting groove 13 can be linear contact.

[0071] Exemplarily, the rotating member 4 can be made of metal material, such as titanium alloy or stainless steel, or can be made of plastic, and the embodiments of the present disclosure are not limited thereto. The rotating member 4 can be formed by drawing process or injection molding process, and the embodiments of the present disclosure are not limited thereto.

[0072] Exemplarily, the rotating member 4 can be an integrally formed part. In this way, the overall strength of the rotating member 4 can be improved.

[0073] In some possible embodiments, the rotating shaft mechanism comprises a plurality of elastic members 2.

[0074] As shown in Figure 2 , the outer side of the mounting protruding structure 100 (i.e. the side away from the nose bridge) has a receiving cavity 11, and the top wall of the mounting protruding structure 100 has an opening 12 which is in communication with the receiving cavity 11. A part of the sliding member 3 is located in the receiving cavity 11, and another part of the sliding member 3 is located outside the receiving cavity 11 and connected with the opening 12 in a sliding manner. The elastic member 2 is located in the receiving cavity 11 and connected with the mounting protruding structure 100 and the sliding member 3 at both ends. The number of the elastic member 2 is multiple, for example, the number of the elastic member 2 is two, three or four, etc.

[0075] As shown in Figure 2The rotating shaft mechanism comprises two elastic members 2, the two elastic members 2 are springs, the two elastic members 2 are located in the accommodating cavity 11 of the fixing member 1, one end of each elastic member 2 is connected with the cavity bottom of the accommodating cavity 11, the other end is connected with the sliding member 3, the two elastic members 2 are parallel and perpendicular to the rotating axis 4a of the rotating member 4.

[0076] The two elastic members 2 are parallel, that is, the axes of the two springs are parallel.

[0077] In this way, by arranging multiple elastic members 2, the pushing force exerted by the elastic member 2 on the sliding member 3 can be improved, so that the clamping force of the rotating member 4 on the user's head is improved.

[0078] In an example, the multiple elastic members 2 are distributed along the extension direction of the rotating axis 4a of the rotating member 4.

[0079] As shown in Figure 2 , the rotating shaft mechanism comprises two elastic members 2, and the axes of the two elastic members 2 and the rotating axis 4a of the rotating member 4 are coplanar.

[0080] By adopting the technical scheme provided in the embodiments of the present disclosure, the multiple elastic members 2 are distributed along the extension direction of the rotating axis 4a of the rotating member 4, on the one hand, during the rotation of the rotating member 4 relative to the fixing member 1, the compression degree of the multiple elastic members 2 can be kept consistent, thereby improving the stability of the rotation of the rotating member 4. On the other hand, the elastic member 2 can avoid occupying too much space in the transverse direction of the smart glasses (the transverse direction is the direction of the connecting line between the two legs), thereby avoiding the transverse size of the smart glasses being too large and being more beautiful.

[0081] In some examples, the accommodating cavity 11 is internally provided with a first protruding structure 111, and the first protruding structure 111 is used to fix one end of the elastic member 2 away from the sliding member 3.

[0082] As shown in Figure 3 , the wall surface of the accommodating cavity 11 away from the opening 12 has a first protruding structure 111, and the first protruding structure 111 extends into one end of the elastic member 2 away from the sliding member 3.

[0083] In an example, as shown in Figure 3 , the rotating shaft mechanism comprises two elastic members 2, and the two elastic members 2 are distributed along the rotating axis 4a of the rotating member 4, and correspondingly, the wall surface of the accommodating cavity 11 away from the opening 12 has two first protruding structures 111, and each first protruding structure 111 extends into one elastic member 2.

[0084] Further, referring to Figure 3In some possible embodiments, the first protruding structure 111 can be a cylindrical protrusion, and the outer diameter of the first protruding structure 111 can be equal to the inner diameter of the elastic member 2. In this way, the connection stability between the elastic member 2 and the fixing member 1 can be improved.

[0085] In some possible embodiments, the sliding member 3 comprises a sliding portion 31 and a limiting portion 32.

[0086] As shown in Figure 3 , the sliding portion 31 is adapted to the shape and size of the opening 12, and is located in the opening 12 and connected to the opening 12 in a sliding manner. The limiting portion 32 can cover the opening 12, and is located in the accommodating cavity 11 and abuts against the edge of the opening 12.

[0087] Specifically, referring to Figure 4 , the sliding portion 31 has a columnar structure, and the cross section of the sliding portion 31 can be a rounded rectangle. The sliding portion 31 is connected to the top wall of the limiting portion 32. The limiting portion 32 has a cubic structure, and the length of the top wall of the limiting portion 32 is greater than the length of the opening 12, and the width of the top wall of the limiting portion 32 is greater than the width of the opening 12. In this way, the sliding member 3 can be prevented from being pulled out of the accommodating cavity 11.

[0088] Exemplarily, the sliding portion 31 can be made of plastic, and the sliding portion 31 can be formed by a pressurized injection molding process.

[0089] In an example, as shown in Figure 3 and Figure 4 , the limiting portion 32 has a second protruding structure 321 on the wall surface away from the opening 12, and the second protruding structure 321 extends into the other end of the elastic member 2.

[0090] Further, the second protruding structure 321 can be a cylindrical protrusion, and the outer diameter of the second protruding structure 321 can be equal to the inner diameter of the elastic member 2. In this way, the connection stability between the elastic member 2 and the sliding member 3 can be improved.

[0091] In some examples, the elastic member 2 is located in the accommodating cavity 11, and the elastic member 2 is always in a compressed state.

[0092] As shown in Figure 3 , the sliding member 3 comprises a sliding portion 31 and a limiting portion 32. The sliding portion 31 is located in the opening 12, and the limiting portion 32 is located in the accommodating cavity 11 and connected to the sliding portion 31. The distance between the wall surface of the limiting portion 32 away from the sliding portion 31 and the bottom of the accommodating cavity 11 is less than the natural length of the elastic member 2.

[0093] Using the technical solution provided in this embodiment, since the distance from the wall of the limiting part 32 away from the sliding part 31 to the bottom of the cavity 11 is less than the natural length of the elastic member 2, the elastic member 2 is always in a compressed state. Therefore, when the rotating shaft mechanism is not subjected to external force, the elastic member 2 always applies a thrust to the limiting part 32, which enables the limiting part 32 to remain abutted against the edge of the opening 12.

[0094] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0095] This disclosure provides a hinge structure applicable to smart glasses. In this hinge mechanism, a rotating member 4 is rotatably connected to a fixed member 1. When the rotating member 4 rotates in the forward direction, it pushes a sliding member 3 into the receiving cavity 11, compressing the elastic member 2 and causing elastic deformation. The compressed elastic member 2 applies a thrust to the rotating member 4, which generates a torque that drives the rotating member 4 to rotate in the opposite direction, thereby improving the clamping effect of the temples on the user's head and making the smart glasses less likely to fall off. Since the elastic member 2 is a spring, compared to related technologies using silicone as the elastic member, the spring is less prone to failure in humid and hot environments, thus extending the service life of the hinge mechanism.

[0096] This disclosure also provides a smart glasses, which includes the aforementioned rotating mechanism, with the frame of the smart glasses being the aforementioned fixing member 1 and the temples of the smart glasses being the aforementioned rotating member 4. Figures 7-9 This is a schematic diagram of the structure of smart glasses provided in an embodiment of this disclosure. See also: Figure 7 When rotating component 4 is in its retracted state and at its first extreme position, it cannot continue to rotate in the opposite direction. (See also...) Figure 8 The smart glasses are in the unfolded state, and the fixing component is in the second extreme position. At this time, the rotating component 4 is in contact with the sliding component 3, but the rotating component 4 does not exert any force on the sliding component 3. If the user does not apply additional torque to the rotating component 4, the rotating component 4 cannot continue to rotate forward relying solely on its own weight. See also Figure 9 When the fixed part is in the third limit position, the rotating part 4 pushes the sliding part 3 completely into the opening 12 (not shown), and the end of the rotating part 4 abuts against the fixed part 1, so the rotating part 4 can no longer rotate in the forward direction.

[0097] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
