Abstract

Technical Field
[0001] This application relates to the field of smart glasses technology, and more particularly to a hinge module and smart glasses. Background Technology
[0002] Currently, based on different communication methods, smart glasses on the market can be roughly divided into two categories. One type uses wireless connections such as Bluetooth to connect the electronic modules within the temples, suitable for traditional eyeglass hinges. The other type uses wired connections such as FPCs (flexible printed circuit boards) to connect the electronic modules within the temples. For this type of product, traditional eyeglass hinges lack the internal wiring space for FPCs, limiting their function to a mere rotation mechanism and failing to meet the wired communication requirements of the embedded electronic modules in smart glasses. Utility Model Content
[0003] The purpose of this application is to provide a hinge module and smart glasses, which aims to improve the problem that traditional glasses hinges can only serve as a rotation mechanism and cannot meet the wired connection and communication requirements of the embedded electronic modules in smart glasses products.
[0004] To achieve this objective, embodiments of this application provide a hinge module for a flip connection between the frame assembly and temples of smart glasses. The hinge module includes a fixing component, a hinge component, and a screw connector. The fastener is provided with a first wire hole and a first arc surface, and the fastener is installed on the frame assembly; The pivot component is provided with a second wire hole and a second arc surface, and the pivot component is mounted on the temple of the mirror. The screw connector is configured to connect the second wire hole to the first wire hole by rotating the shaft to the fixing member. The second arc surface faces the first arc surface, and a first gap is reserved between the second arc surface and the first arc surface. The first gap is configured to achieve a clearance fit between the first arc surface and the second arc surface in the rotation direction of the shaft, so as to cooperate with the pre-locking force provided by the screw connector to the connection between the fixing member and the shaft, so that the shaft module has rotational torque, so that the shaft can rotate relative to the fixing member around the central axis of the screw connector.
[0005] Optionally, in some embodiments of this application, the spacing of the first gap is 0.07 mm to 0.13 mm.
[0006] Optionally, in some embodiments of this application, the fastener is further provided with a first receiving groove, which is configured to at least partially and movably receive the rotating shaft. The first receiving groove includes a first groove wall, which is parallel to the central axis of the screw connector, and the first groove wall is provided with the first wire hole. The groove opening of the first receiving groove is provided with the first arc surface.
[0007] Optionally, in some embodiments of this application, the first receiving groove further includes two second groove walls, which are arranged opposite to each other in the extension direction of the central axis of the screw connector. One side of each second groove wall is connected to the first groove wall, and the other side of each second groove wall is provided with the first arc surface.
[0008] Optionally, in some embodiments of this application, each of the second groove walls is provided with a first shaft connection hole for correspondingly inserting the screw connector.
[0009] Optionally, in some embodiments of this application, the first arc surface is a circular arc surface, and the center of the first rotating shaft connecting hole coincides with the center of the circular arc surface.
[0010] Optionally, in some embodiments of this application, the rotating shaft is further provided with a second rotating shaft connecting hole for correspondingly passing through the screw connector; The extension direction of the second rotating shaft connecting hole is perpendicular to the plane containing the extension direction of the second wire passing hole, and the second rotating shaft connecting hole and the second wire passing hole are not connected to each other.
[0011] Optionally, in some embodiments of this application, the rotating shaft includes a first rotating shaft seat and a second rotating shaft seat, wherein, The first rotating shaft seat is provided with a second receiving groove. The second receiving groove includes a third groove wall and two fourth groove walls. The two fourth groove walls are arranged opposite to each other in the extension direction of the central axis of the screw connector, and one side of the two fourth groove walls is connected together through the third groove wall. Each fourth groove wall is provided with a first sub-connection hole. The second rotating shaft seat has a second sub-connecting hole. The second rotating shaft seat is detachably installed in the second receiving groove, and the center of the second sub-connecting hole is located on the center line between the two first sub-connecting holes, so that the second sub-connecting hole and the two first sub-connecting holes together form the second rotating shaft connecting hole. A second gap is also reserved between the side of the second rotating shaft seat facing the third groove wall and the third groove wall to form the second wire passage hole.
[0012] Optionally, in some embodiments of this application, the first rotating shaft seat body is further provided with a second arc surface, the second arc surface being located on the side of any of the fourth groove walls away from the other fourth groove wall, and the second arc surface is a circular arc surface, the center of the first sub-connecting hole coinciding with the center of the circular arc surface; and / or, The second rotating shaft seat can be detachably installed in the second receiving groove through a snap-fit structure or an interference fit structure. In addition, to achieve this purpose, this application embodiment also provides a smart glasses, the smart glasses including a glasses body and the above-mentioned hinge module, the glasses body including a frame assembly and two temples, the two temples are respectively disposed on two opposite sides of the frame assembly, and each temple is flipped and connected to the corresponding side of the frame assembly through a hinge module.
[0013] The hinge module and smart glasses provided in this application, through the above-described structural configuration, achieve the following: Firstly, when the fixing component and the hinge component of the hinge module are rotatably connected via screws, the second arc surface of the hinge component and the first arc surface of the fixing component are directly opposite each other, with a first gap between them. This first gap allows for a clearance fit between the first and second arc surfaces in the rotational direction of the hinge component, which, in conjunction with the pre-locking force provided by the screws to the connection between the fixing component and the hinge component, causes the hinge module to have rotational torque. This enables the hinge component to rotate relative to the fixing component around the central axis of the screws, thus achieving the flipping function of the temples in the smart glasses using this hinge module. Secondly, when the fixing component and the hinge component of the hinge module are rotatably connected via screws, the second wire hole of the hinge component is connected to the first wire hole of the fixing component. In this way, the first and second wire-passing holes can be used together to reserve wire passage positions such as FPCs inside the hinge module, thus effectively meeting the wired connection and communication requirements of the embedded electronic modules in smart glasses using this hinge module. It is evident that the technical solution of this application effectively improves the problem that traditional eyeglass hinges can only function as rotation mechanisms and cannot meet the wired connection and communication requirements of the embedded electronic modules in smart glasses products.

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

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.
[0020] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] Please see Figures 1 to 6 As shown, in one embodiment, this application provides a hinge module 10, which specifically includes a fixing member 11, a hinge member 12, and a screw connector 13. The fixing member 11 has a first wire hole 111 and a first arc surface 112, and is mounted on the frame assembly 21. The hinge member 12 has a second wire hole 123 and a second arc surface 1211, and is mounted on the temple 22. The screw connector 13 is configured to connect the second wire hole 123 to the first wire hole 111 by rotating the hinge member 12 to the fixing member 11. The second arc surface 1211 faces the first arc surface 112, and a first gap 14 is reserved between the second arc surface 1211 and the first arc surface 112. The first gap 14 is configured to achieve a clearance fit between the first arc surface 112 and the second arc surface 1211 in the rotation direction of the pivot member 12. This fits with the pre-locking force provided by the screw connector 13 to the connection between the fixing member 11 and the pivot member 12, thereby giving the pivot module 10 rotational torque so that the pivot member 12 can rotate relative to the fixing member 11 around the central axis of the screw connector 13. The mounting of the fixing member 11 on the frame assembly 21 and the mounting of the pivot member 12 on the temple 22 can be achieved through detachable structures such as snap-fit structures or interference fit structures, so that the components of the entire pivot module 10 can be disassembled and replaced as needed.
[0022] It should be noted that the hinge module 10 in this embodiment is mainly used in smart glasses 1 to realize the flip connection between the frame assembly 21 and the corresponding temples 22. That is, each temple 22 of smart glasses 1 can be flipped to the frame assembly 21 through a hinge module 10. Generally speaking, in addition to the frame assembly 21 and two temples 22 found in ordinary glasses, smart glasses 1 also has various electronic modules installed in the frame assembly 21 and temples 22. These electronic modules include, but are not limited to, power modules, control circuit boards, audio modules, microphones, cameras, and various sensors. When these electronic modules are working, they need to be wired to achieve electrical and communication connections through cables such as FPCs. Since these electronic modules are generally distributed within the frame assembly 21 and different temples 22, in smart glasses 1 using this hinge module 10, wires such as FPCs within the temples 22 can be led out through the second wire hole 123 and then introduced into the frame assembly 21 via the first wire hole 111. Similarly, wires such as FPCs within the frame assembly 21 can be led out through the first wire hole 111 and then introduced into the corresponding temples 22 via the second wire hole 123. To avoid the rotation of the hinge 12 from adversely affecting the wire passage through the second wire hole 123, the opening position of the second wire hole 123 is generally designed to avoid the installation position of the screw connector 13.
[0023] Furthermore, in this embodiment, the first gap 14 achieves a clearance fit between the first arc surface 112 and the second arc surface 1211 in the rotation direction of the rotating shaft 12, which is used to cooperate with the pre-locking force provided by the screw connector 13 for the connection between the fixing member 11 and the rotating shaft 12. This allows the rotating shaft module 10, with its single screw connector 13 structure design, to have sufficient rotational torque, enabling the rotating shaft 12 to rotate relative to the fixing member 11 around the central axis of the screw connector 13. In this way, the problem of uneven torque caused by the use of double screw connectors 13 for fixing in some existing rotating shaft structures can be effectively avoided.
[0024] In this way, the pivot module 10 of this embodiment, through the above-described structural arrangement, on the one hand, when its fixing member 11 and pivot member 12 are rotatably connected by the screw connector 13, the second arc surface 1211 of the pivot member 12 is directly opposite to the first arc surface 112 of the fixing member 11, and a first gap 14 is reserved between them. Thus, the first arc surface 112 and the second arc surface 1211 can be fitted in the rotation direction of the pivot member 12 through the first gap 14, which can cooperate with the pre-locking force provided by the screw connector 13 for the connection between the fixing member 11 and the pivot member 12, so that the pivot module 10 has rotational torque, thereby enabling the pivot member 12 to rotate relative to the fixing member 11 around the central axis of the screw connector 13. This rotational movement can realize the rotational function of each temple 22 in the smart glasses 1 using this pivot module 10. On the other hand, when the fixing member 11 and the rotating shaft member 12 are rotatably connected by the screw connector 13, the second wire passage hole 123 of the rotating shaft member 12 is also connected to the first wire passage hole 111 of the fixing member 11. In this way, the first wire passage hole 111 and the second wire passage hole 123 can be used together to reserve wire passage positions such as FPC inside the rotating shaft module 10, so as to well meet the wired connection communication requirements of the embedded electronic module in the smart glasses 1 using this rotating shaft module 10.
[0025] In some examples, such as Figure 2 As shown, the spacing of the first gap 14 is 0.07 mm to 0.13 mm. Thus, through the above parameter settings, the small gap design formed between the first arc surface 112 and the second arc surface 1211 allows for better clearance fit between the first arc surface 112 and the second arc surface 1211 in the rotation direction of the rotating shaft 12. This fits with the pre-locking force provided by the screw connector 13 to the connection between the fixing member 11 and the rotating shaft 12, ensuring that the rotating shaft module 10 has sufficient rotational torque.
[0026] In some examples, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixing member 11 is also provided with a first receiving groove 113, which is configured to at least partially accommodate the rotating shaft member 12. The first receiving groove 113 includes a first groove wall 1131, which is parallel to the central axis of the screw connector 13, and a first wire through hole 111 is provided on the first groove wall 1131. The groove opening of the first receiving groove 113 has a first arc surface 112 along its edge. Thus, with the above structural configuration, the rotating shaft member 12 can be at least partially accommodated in the first receiving groove 113 on the fixing member 11, and can rotate relative to the fixing member 11 around the central axis of the screw connector 13.
[0027] In some examples, such as Figure 2 , Figure 3 and Figure 4 As shown, the first receiving groove 113 also includes two second groove walls 1132, which are arranged opposite to each other in the extension direction of the central axis of the screw connector 13. One side of each second groove wall 1132 is connected to the first groove wall 1131, and the other side of each second groove wall 1132 is provided with a first arc surface 112. Thus, with the above structural arrangement, when the rotating shaft 12 is at least partially movably received in the first receiving groove 113 on the fixing member 11, its second arc surface 1211 can be well aligned with the first arc surface 112.
[0028] In some examples, such as Figure 2 , Figure 3 and Figure 4 As shown, each second groove wall 1132 is provided with a first rotating shaft connection hole 114 for correspondingly inserting a screw connector 13. Thus, through the above structural arrangement, the insertion direction of the screw connector 13 on the fixing member 11 is perpendicular to the opening direction of the first wire passage hole 111. This ensures that the opening position of the first wire passage hole 111 effectively avoids the installation position of the screw connector 13, thereby preventing adverse effects of the rotation of the rotating shaft member 12 on the wire passage of the first wire passage hole 111.
[0029] In some examples, such as Figure 2 , Figure 3 and Figure 4 As shown, the first arc surface 112 is a circular arc surface, and the center of the first rotating shaft connecting hole 114 coincides with the center of the circular arc surface. Thus, through the above structural arrangement, combined with the circular arc surface design of the second arc surface 1211 mentioned later, when the rotating shaft 12 rotates relative to the fixing member 11 around the central axis of the screw connector 13, the first arc surface 112 can well achieve a corresponding clearance fit with the opposite second arc surface 1211 in the rotation direction of the rotating shaft 12.
[0030] In some examples, such as Figure 2 , Figure 3 and Figure 5 As shown, the rotating shaft 12 is also provided with a second rotating shaft connecting hole for correspondingly threading the screw connector 13. The extension direction of the second rotating shaft connecting hole is perpendicular to the plane containing the extension direction of the second wire passage hole 123, and the second rotating shaft connecting hole and the second wire passage hole 123 are not connected to each other. Through the above structural arrangement, the opening position of the second wire passage hole 123 can effectively avoid the installation position of the screw connector 13, thereby avoiding the adverse effects of the rotation of the rotating shaft 12 on the wire passage of the second wire passage hole 123.
[0031] It should be noted that the second shaft connection hole in this example can be a smooth hole structure (i.e., the inner side of the second shaft connection hole is smooth), while the first shaft connection hole 114 mentioned in the above example can be a threaded hole structure (i.e., the inner side of the first shaft connection hole 114 is provided with an internal thread that engages with the screw connector 13). In this way, while the rotating part and the fixed part 11 are locked together by the screw connector 13, the rotating part can also rotate relative to the fixed part 11 around the central axis of the screw connector 13.
[0032] In some examples, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the rotating shaft component 12 includes a first rotating shaft seat 121 and a second rotating shaft seat 122. The first rotating shaft seat 121 is provided with a second receiving groove 1212. The second receiving groove 1212 includes a third groove wall 12121 and two fourth groove walls 12122. The two fourth groove walls 12122 are arranged opposite to each other in the extension direction of the central axis of the screw connector 13, and one side of the two fourth groove walls 12122 is connected together through the third groove wall 12121. Each fourth groove wall 12122 is provided with a first sub-connecting hole 1213. The second shaft seat 122 has a second sub-connecting hole 1221. The second shaft seat 122 is detachably installed in the second receiving groove 1212, and the center of the second sub-connecting hole 1221 is located on the center line between the two first sub-connecting holes 1213, so that the second sub-connecting hole 1221 and the two first sub-connecting holes 1213 together form the second shaft connecting hole. A second gap is also reserved between the side of the second shaft seat 122 facing the third groove wall 12121 and the third groove wall 12121 to form a second wire passage hole 123. In this way, through the above structural arrangement, the opening position of the second wire passage hole 123 can effectively avoid the installation position of the screw connector 13, while the extension direction of the second wire passage hole 123 at least partially coincides with the rotation direction of the shaft 12. This can better avoid the adverse effects of the rotation of the shaft 12 on the wire passage of the second wire passage hole 123.
[0033] It should be noted that in this example, the surface of the third groove wall 12121 facing the second shaft seat 122 and the surface of the second shaft seat 122 facing the third groove wall 12121 are both connected by multiple arc surfaces to form a similar curved surface structure, so that the second wire hole 123 formed between the two is in a certain curved setting, so as to better avoid the installation position of the screw connector 13, while providing better support for the wires such as FPC passing through the second wire hole 123.
[0034] In some examples, such as Figure 2 , Figure 3 , Figure 5and Figure 6 As shown, the first rotating shaft seat 121 is also provided with a second arc surface 1211. The second arc surface 1211 is located on the side of any fourth groove wall 12122 away from the other fourth groove wall 12122, and the second arc surface 1211 is a circular arc surface. The center of the first sub-connecting hole 1213 coincides with the center of the circular arc surface. Thus, with the above structural arrangement, combined with the circular arc surface design of the first arc surface 112 in the example above, when the rotating shaft 12 rotates relative to the fixing member 11 around the central axis of the screw connector 13, the second arc surface 1211 can make a good clearance fit with the opposite first arc surface 112 in the rotation direction of the rotating shaft 12.
[0035] In some examples, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the second pivot seat 122 is detachably installed in the second receiving groove 1212 via a snap-fit structure or an interference fit structure. Thus, this structural arrangement facilitates the installation and removal of the second pivot seat 122 according to actual needs. It should be noted that, in this example, the second pivot seat 122 can be provided with a plug block 1222 protruding on both sides of the extension direction of the central axis of the screw connector 13. At the same time, the second receiving groove 1212 is provided with a plug groove 1214 at the corresponding position. Thus, the second pivot seat 122 can be detachably installed on the second receiving groove 1212 by the interference fit structure formed by the interference fit between each plug block 1222 and the corresponding plug groove 1214.
[0036] In one embodiment, such as Figure 1 As shown, this application embodiment also provides a smart glasses 1, which includes a glasses body 20 and a hinge module 10 as described in the above embodiment. The glasses body 20 includes a frame assembly 21 and two temples 22, which are respectively disposed on two opposite sides of the frame assembly 21. Each temple 22 is flipped and connected to the corresponding side of the frame assembly 21 via a hinge module 10. Thus, since the smart glasses 1 of this application embodiment uses the hinge module 10 of the above embodiment, it realizes the flipping function of each temple 22 in the smart glasses 1 while well meeting the wired connection communication requirements of the embedded electronic module in the smart glasses 1.
[0037] It should be noted that the smart glasses 1 in this application embodiment can specifically be an AR glasses or other glasses product with embedded electronic modules.
[0038] The above-described 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
