[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] The utility model provides a hinge assembly, referring to Figure 1 The hinge assembly 30 is applied to the smart glasses 100, which can be AR (Augmented Reality) glasses, VR (Virtual Reality) glasses or audio glasses. The smart glasses 100 can also be myopia glasses, sunglasses, cycling glasses or other glasses. AR, or augmented reality technology, is a technology that cleverly integrates virtual information with the real world. AR glasses are a type of AR near-eye display device.

[0034] For the sake of ease of explanation, the technical solution of the present application is explained by taking AR glasses as an example. This is only an example and does not limit the smart glasses 100.

[0035] Reference Figures 1 to 7 The hinge assembly 30 includes a fixed part 1, a movable part 2 and a connecting part 3. The fixed part 1 has a fixed end 11 and a connecting end 12, and the fixed end 11 is fixedly connected to the frame 10 of the smart glasses 100. The movable part 2 has a mounting end 21 and a transfer end 22, and the mounting end 21 is fixedly connected to the temple 20 of the smart glasses 100.

[0036] The connecting member 3 is installed on the connecting end 12. The adapter end 22 is provided with a sleeve portion 221, which is sleeved on the connecting member 3. The connecting member 3 and the sleeve portion 221 are in damping contact cooperation, so that the movable member 2 is kept in an unfolded state or a folded state.

[0037] Based on the above-mentioned scheme, the overall structure of the hinge assembly 30 is simple and lightweight, so that the hinge assembly 30 has the advantage of being lightweight, which not only helps to reduce the overall weight of the smart glasses 100, but also facilitates assembly on the smart glasses 100. Such a setting can greatly improve the user's wearing comfort and enhance the user's usage experience. In addition, it can also provide more possibilities for the selection of the size and appearance of the temples 20, thereby improving the aesthetics of the product.

[0038] The connecting member 3 is in damping contact cooperation with the sleeve portion 221, so that the temple 20 can maintain its relative position with the frame 10 after being unfolded, so as to effectively avoid the temple 20 from swinging in a natural state, thereby stably maintaining the angle of the temple 20 relative to the frame 10, so as to facilitate the user to wear, thereby improving the folding feel of the temple 20 and the wearing comfort of the smart glasses 100.

[0039] In addition, the overall structure of the hinge assembly 30 is compact, which helps to reduce the installation space required for the hinge assembly 30. This can reasonably improve the space utilization of the smart glasses 100, reduce unnecessary structural designs, and help reduce the weight of the smart glasses 100.

[0040] The connecting member 3 is a shaft structure or a rod structure, such as a connecting shaft or a connecting rod. The movable member 2 can be made of spring steel, which has good wear resistance and toughness. The connecting member 3 can be made of high carbon steel, which can meet the wear resistance requirements between the movable member 2 and the connecting member 3, ensuring that the hinge assembly 30 can be used for a long time.

[0041] Continue to refer to Figures 1 to 7 The sleeve portion 221 is provided with a sleeve hole 2211, and the outer peripheral wall of the connecting member 3 is in damping contact with the hole wall of the sleeve hole 2211. With such a configuration, when the movable member 2 rotates around the axis of the connecting member 3, a clamping force can be generated between the hole wall of the sleeve hole 2211 and the outer peripheral wall of the connecting member 3, so that the movable member 2 can be ensured to rotate relative to the fixed member 1, and the angle of the movable member 2 relative to the fixed member 1 after rotation can be fixed, effectively preventing the angle of the movable member 2 relative to the fixed member 1 from changing after rotation, that is, ensuring the unfolding stability of the temple 20, so as to facilitate the user to wear.

[0042] In addition, the hinge assembly 30 of the technical solution of the present application can achieve angle fixation between the movable part 2 and the fixed part 1, that is, maintain the angle between the temple 20 and the frame 10 after unfolding, without the need for an additional damping structure. The overall structure is simple and lightweight, which saves time when assembling the hinge assembly 30 and helps to improve installation efficiency.

[0043] Continue to refer to Figures 1 to 7The hole wall of the sleeve hole 2211 is formed with a curved wall 2212 and a plane wall 2213, which are connected to each other, and the outer peripheral wall of the connector 3 is formed with a sliding wall 31, a first stop wall 32 and a second stop wall 33, which are arranged at an angle, and the curved wall 2212 is in sliding contact with the sliding wall 31. In the folded state, the plane wall 2213 is in plane contact with the first stop wall 32; in the unfolded state, the plane wall 2213 is in plane contact with the second stop wall 33.

[0044] With such arrangement, the position of the movable part 2 can be fixed only by the first stop wall 32 and the second stop wall 33 on the connecting part 3, and the shaking of the temple 20 can be effectively avoided by surface contact. The stopping method is simple and effective, and can greatly improve the damping coordination performance between the movable part 2 and the connecting part 3.

[0045] In the folded state, the temple 20 is folded, the curved wall 2212 is in contact with the sliding wall 31, and the plane wall 2213 is in surface contact with the first stop wall 32. In the unfolded state, the movable part 2 and the fixed part 1 tend to be arranged linearly. When the temple 20 is gradually unfolded, the curved wall 2212 is in sliding contact with the sliding wall 31, and the plane wall 2213 gradually breaks away from the contact with the first stop wall 32 and gradually contacts the second stop wall 33, until the plane wall 2213 is in complete surface contact with the second stop wall 33.

[0046] The first stop wall 32 and the second stop wall 33 are arranged at an acute angle. This arrangement allows the movable part 2 to be unfolded as much as possible, ensuring the unfolding range required by the movable part 2, that is, the unfolding range required by the temple 20, so as to meet the wearing size required by different users' heads; on the other hand, the movable part 2 can be rotated around the axis of the connecting part 3 within a reasonable range, effectively reducing the obstacle of the plane wall 2213 switching contact between the first stop wall 32 and the second stop wall 33, thereby ensuring that the temple 20 can be smoothly turned or folded, thereby improving the performance of the hinge assembly 30, improving the reliability of the smart glasses 100, and improving the comfort of the user.

[0047] The outer peripheral wall of the connecting member 3 is formed with a guide portion 34, which is located between the first stop wall 32 and the second stop wall 33. The guide portion 34 is in sliding contact with the plane wall 2213, and is used to guide the rotation of the sleeve portion 221. In this way, when the movable member 2 is unfolded relative to the fixed member 1, the plane wall 2213 can smoothly slide from the first stop wall 32 to the second stop wall 33, or when the movable member 2 is folded relative to the fixed member 1, the plane wall 2213 can smoothly slide from the second stop wall 33 to the first stop wall 32, so that the user can have a good operating feel when unfolding or folding the temple 20, thereby improving the user's comfort.

[0048] In addition, the curved wall 2212 can also be in sliding contact with the guide portion 34, so that the temple 20 is expanded as far away from the human face as possible (such as Figure 7 As shown), to adapt to users with larger head sizes, thereby improving the usability of the hinge assembly 30 and improving the applicability of the smart glasses 100.

[0049] The fixing member 1 has a stop wall 13. When the temple 20 expands outwardly as far away from the human face as possible, the stop wall 13 stops the movable member 2 from rotating to limit the expansion amount of the temple 20, thereby effectively avoiding the phenomenon of the temple breaking due to excessive expansion.

[0050] The guide portion 34 may be a guide curved wall or a side wall surface arranged in an arc shape.

[0051] Continue to refer to Figures 1 to 7 The sleeve part 221 is provided with a notch 2214, and the notch 2214 is communicated with the sleeve hole 2211. With such a configuration, when the sleeve part 221 contacts the outer peripheral wall of the connecting member 3 and rotates around the axis of the connecting member 3, the sleeve part 221 is easily deformed, which not only helps the sleeve part 221 to rotate smoothly, that is, improves the smoothness of unfolding or folding the temple 20, but also enhances the clamping force of the sleeve part 221 and the connecting member 3, thereby improving the connection stability between the movable member 2 and the connecting member 3 and improving the performance of the hinge assembly 30.

[0052] There are two sleeve portions 221, which are arranged at intervals, and both sleeve portions 221 are sleeved on the connecting member 3. By sleeve-engaging the two sleeve portions 221 with the connecting member 3, the connection stability between the movable member 2 and the connecting member 3 can be further improved, the possibility of failure of the damping fit between the movable member 2 and the connecting member 3 can be effectively reduced, the clamping force between the movable member 2 and the connecting member 3 can be increased, and the stability of maintaining the angle of the temple 20 relative to the frame 10 can be improved.

[0053] Continue to refer to Figures 1 to 7The hinge assembly 30 also includes a protective member 4, which is sleeved on the outside of the connecting member 3 and is arranged between the two sleeve connecting parts 221. One end of the protective member 4 abuts against one of the two sleeve connecting parts 221, and the other end abuts against the other of the two sleeve connecting parts 221.

[0054] On the one hand, the protective member 4 can effectively reduce the deformation of the contact portion between the movable member 2 and the connecting member 3 to a certain extent, that is, the two sleeve connecting parts 221 are not easy to deform. Under the action of the protective member 4, the two sleeve connecting parts 221 are supported, so that the sleeve connecting parts 221 can maintain stable contact with the connecting member 3, thereby improving the damping force of the movable member 2 and the connecting member 3; on the other hand, the protective member 4 makes the structure between the movable member 2 and the connecting member 3 more compact, and can also protect the connecting member 3, effectively preventing the outer peripheral wall of the protective member 4 from being knocked by other structures, ensuring that the connecting member 3 is stably connected to the movable member 2, improving the durability of the hinge assembly 30, and improving the performance of the smart glasses 100.

[0055] The protective member 4 may be a sleeve or a protective shell, or may be other structural members with protective performance, which is not specifically limited here.

[0056] Continue to refer to Figures 1 to 7 The connecting end 12 is provided with two branches 121, the two branches 121 are arranged at an interval, and the two branches 121 are both provided with a mounting hole 1211, one end of the connecting member 3 is arranged in one of the two mounting holes 1211, and the other end is arranged in the other of the two mounting holes 1211.

[0057] Through the above-mentioned installation method, there is no need to fix the connecting member 3 by screws, which helps to reduce the weight of the hinge assembly 30, and the installation is convenient and fast, which helps to improve the efficiency of installation.

[0058] The shape of the mounting hole 1211 is adapted to the outer peripheral wall of the connecting member 3 so as to limit the connecting member 3 from rotating along its own circumferential direction, so that the connecting member 3 can be stably assembled on the fixing member 1 to improve the stability of the hinge assembly 30 .

[0059] The utility model provides a kind of smart glasses, referring to Figure 1 The smart glasses 100 include a frame 10 , temples 20 and a hinge assembly 30 .

[0060] The specific structure of the hinge assembly 30 refers to the above embodiments. Since the smart glasses 100 adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0061] The frame 10 is equipped with a lens assembly and an optical machine. The lens assembly may include a waveguide sheet and an optical lens. The waveguide sheet and the optical lens are stacked, the waveguide sheet is arranged close to the human face, and the optical lens is arranged away from the human face. The optical machine can be fixed on the waveguide sheet by dispensing glue. The optical machine is used to output light toward the waveguide sheet and conduct it through the waveguide sheet to form an image on the waveguide sheet and transmit it to the user's eyes, thereby realizing the display function.

[0062] The optical machine can be a Micro LED optical machine, a Micro OLED optical machine, a DLP optical machine, an Lcos optical machine or an LBS optical machine. This is only an example and is not limited.

[0063] It can be understood that the number of waveguide plates, optical lenses and optical machines are all two, so as to completely assemble the smart glasses 100, which is convenient for users to use and provides users with a complete user experience.

[0064] The smart glasses 100 may also include an electric control component, which includes a battery, a control board, and a flexible circuit board. The flexible circuit board is electrically connected to the control board and the optical machine, and the battery is electrically connected to the control board. The control board can control the operation of the optical machine, and the battery is used to power the optical machine. It can be understood that the battery is installed in one of the temples 20 of the smart glasses 100, and the control board is installed in another temple 20 of the smart glasses 100, so as to completely assemble the entirety of the smart glasses 100.
