Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and in particular to a hinge assembly and smart glasses. Background Technology

[0002] With the diversification of eyewear, some AR glasses have appeared on the market. AR glasses usually have optical components installed in the frame and electronic components such as batteries and control boards installed in the temples. The optical components and control boards are electrically connected through flexible circuit boards. Relatively speaking, AR glasses are heavier.

[0003] The frame and temples of AR glasses are connected by hinges. Because of the components inside the AR glasses, the hinges currently used are not very effective in controlling the positioning angle of the temples when rotating them, which affects the user experience. Utility Model Content

[0004] This invention mainly provides a hinge assembly to solve the problem that the hinge used in current AR glasses has poor positioning effect on the temples.

[0005] To achieve the above objectives, this utility model proposes a hinge assembly, which includes a fixed component, a movable component, and an elastic limiting component; wherein,

[0006] The fixing member is fixedly connected to the frame of the smart glasses, one end of the movable member is fixedly connected to the temple of the smart glasses, and the other end is rotatably connected to the fixing member. One end of the elastic limiting member is connected to the fixing member, and the other end is abuttingly connected to the movable member.

[0007] The movable component has an extended state and a retracted state. When the movable component is subjected to an external force, it can switch between the extended state and the retracted state. The elastic limiting component always provides a limiting force for the movable component between the extended state and the retracted state, so that the angle between the movable component and the fixed component remains fixed.

[0008] In some embodiments of this utility model, the movable member has a sliding contact portion, which is arc-shaped. When the movable member switches between the unfolded state and the retracted state, the sliding contact portion elastically abuts against the elastic limiting member to provide a clamping force for the movable member, so that the movable member remains fixed relative to the fixed member.

[0009] In some embodiments of this utility model, the movable member has a first contact portion. When in the unfolded state, the elastic limiting member abuts against the plane of the first contact portion, and the elastic limiting member elastically presses against the movable member, so that the movable member is held in the unfolded state.

[0010] In some embodiments of this utility model, the movable member has a second contact portion. In the closed state, the elastic limiting member abuts against the plane of the second contact portion, and the elastic limiting member elastically presses against the movable member, so that the movable member is held in the closed state.

[0011] In some embodiments of this utility model, the fixing member has two connecting parts, a rotation notch is formed between the two connecting parts, and each of the two connecting parts is provided with a mounting hole. The movable member includes a rotating body and a connecting body, one end of the rotating body extends into one of the two mounting holes, and the other end extends into the other of the two mounting holes.

[0012] The connector is fixedly connected to the temple of the smart glasses, and the rotating notch provides clearance for the rotation of the connector.

[0013] In some embodiments of this utility model, the outer peripheral wall of the rotating body is interference-fitted with the wall of each of the mounting holes.

[0014] In some embodiments of this utility model, each of the connecting portions has an installation notch, and the installation notch communicates with the installation hole.

[0015] In some embodiments of this utility model, the elastic limiting member includes an installation section, a bending section, and an abutting section connected in sequence. The fixing member is provided with an insertion hole and an assembly port. The installation section extends into the insertion hole. The bending section is connected to the fixing member and passes through the assembly port. The abutting section is disposed on a different side from the bending section. The abutting section abuts against the movable member.

[0016] In some embodiments of this utility model, the abutting section is frame-shaped; or, the abutting section is plate-shaped.

[0017] To achieve the above objectives, this utility model also proposes a smart glasses, which includes a frame, temples, and a hinge assembly, wherein the hinge assembly is used to connect the frame and the temples.

[0018] The beneficial effects of this utility model are as follows: Unlike the prior art, the hinge assembly disclosed in this utility model provides limiting force for the moving part through an elastic limiting member, so that when the moving part rotates relative to the fixed part, the angle between the moving part and the fixed part can be stably fixed, ensuring the positioning effect of the moving part and the fixed part, making it less likely for the moving part and the fixed part to loosen. At the same time, the elastic limiting member can also provide users with a good operating feel and improve the user experience during use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0031] This utility model proposes a hinge assembly, referring to... Figure 1 This hinge assembly is used in smart glasses, which can be AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, or audio glasses. Smart glasses can also be prescription glasses, sunglasses, cycling glasses, or other types of glasses. AR, or Augmented Reality, is a technology that cleverly integrates virtual information with the real world; AR glasses are a type of AR near-eye display device.

[0032] For ease of explanation, this application uses AR glasses as an example to illustrate the technical solution. This is only an example and does not limit the application to smart glasses.

[0033] Reference Figures 1 to 3 The hinge assembly includes a fixed component 1, a movable component 2, and an elastic limiting component 3. The fixed component 1 is fixedly connected to the frame of the smart glasses. One end of the movable component 2 is fixedly connected to the temple of the smart glasses, and the other end is rotatably connected to the fixed component 1. One end of the elastic limiting component 3 is connected to the fixed component 1, and the other end abuts against the movable component 2. The movable component 2 has an extended state and a retracted state. When subjected to external force, the movable component 2 can switch between the extended and retracted states. The elastic limiting component 3 always provides a limiting force for the movable component 2 between the extended and retracted states, keeping the angle between the movable component 2 and the fixed component 1 fixed.

[0034] Based on the above scheme, the elastic limiting component 3 provides limiting force for the movable component 2, so that when the movable component 2 rotates relative to the fixed component 1, the angle between the movable component 2 and the fixed component 1 can be stably fixed, ensuring the positioning effect of the movable component 2 and the fixed component 1, so that the movable component 2 and the fixed component 1 are not prone to loosening. This allows the temple to maintain its relative position with the frame after it is unfolded, effectively preventing the temple from swinging in its natural state, thereby stably maintaining the angle of the temple relative to the frame for easy wearing by the user.

[0035] Meanwhile, the elastic limiter 3 also provides users with a good operating feel, thereby improving the folding feel of the temples and enhancing the user experience during use.

[0036] Furthermore, the hinge assembly has a simple and lightweight overall structure, which gives it a lightweight advantage. This not only helps to reduce the overall weight of the smart glasses, but also makes it easy to assemble on the smart glasses. This design can greatly improve the user's wearing comfort and user experience. In addition, it can provide more possibilities for the choice of temple size and appearance, thus improving the aesthetics of the product.

[0037] Reference Figure 3 The movable part 2 has a sliding contact part 221, which is arc-shaped. When the movable part 2 switches between the unfolded state and the retracted state, the sliding contact part 221 elastically abuts against the elastic limiting member 3 to provide a clamping force for the movable part 2, so that the movable part 2 remains fixed relative to the fixed member 1.

[0038] During rotation, the movable part 2 makes elastic contact with the elastic limiting part 3 through the sliding contact part 221. That is, under the action of the elastic limiting part 3, the clamping force between the movable part 2 and the fixed part 1 is enhanced, so that the angle between the movable part 2 and the fixed part 1 can be fixed. At the same time, it can also provide a good operating feel during rotation, which helps to improve the user's user experience.

[0039] The movable part 2 has a first contact portion 222. In the unfolded state, the elastic limiting member 3 abuts against the plane of the first contact portion 222, and the elastic limiting member 3 elastically presses against the movable part 2, keeping the movable part 2 in the unfolded state. This configuration, through the contact between the first contact portion 222 and the plane of the elastic limiting member 3, restricts the rotation or swaying of the movable part 2. Thus, in the absence of external force, the movable part 2 can maintain a fixed position relative to the fixed member 1, making it less prone to loosening and easier for the user to wear. This effectively controls the positioning angle between the movable part 2 and the fixed member 1.

[0040] Furthermore, when in the unfolded state, the movable part 2 can also press the elastic limiting part 3 away from the user's head under the action of external force, thus realizing the expansion of the temples to adapt to the size of different users' heads, thereby increasing the applicability of the smart glasses and improving the user's experience.

[0041] The movable component 2 has a second contact portion 223. In the folded state, the elastic limiting member 3 abuts against the plane of the second contact portion 223, and the elastic limiting member 3 elastically presses against the movable component 2, keeping the movable component 2 in the folded state. This arrangement, by having the second contact portion 223 contact the plane of the elastic limiting member 3, restricts the rotation of the movable component 2, making it less prone to loosening and keeping the movable component 2 in the folded state. This effectively controls the positioning angle between the movable component 2 and the fixing member 1, thereby improving the folding and storage efficiency of the smart glasses.

[0042] The sliding contact portion 221 is located between the first contact portion 222 and the second contact portion 223. Both the first contact portion 222 and the second contact portion 223 can be planes, or they can be other components that have a limiting cooperation with the elastic limiting member 3. As long as it can ensure that the movable member 2 is limited to the unfolded state or the retracted state, no limitation is made here.

[0043] Continue to refer to Figure 1 and Figure 2 The fixing member 1 has two connecting parts 11, with a rotation notch 12 formed between the two connecting parts 11. Both connecting parts 11 are provided with mounting holes 111. The movable member 2 includes a rotating body 21 and a connecting body 22. One end of the rotating body 21 extends into one of the two mounting holes 111, and the other end extends into the other of the two mounting holes 111. The connecting body 22 is fixedly connected to the temple of the smart glasses, and the rotation notch 12 provides clearance for the rotation of the connecting body 22.

[0044] It is understood that the sliding contact portion 221, the first contact portion 222, and the second contact portion 223 are all formed on the connecting body 22.

[0045] The outer peripheral wall of the rotating body 21 is interference-fitted with the wall of each mounting hole 111. This arrangement increases the friction between the outer peripheral wall of the rotating body 21 and the wall of each mounting hole 111, thereby increasing the clamping force between the movable part 2 and the fixed part 1. As a result, after the movable part 2 rotates relative to the fixed part 1, the angle between the movable part 2 and the fixed part 1 can be maintained without the need for an external structure.

[0046] Each connecting part 11 has a mounting notch 112, which communicates with the mounting hole 111. This arrangement facilitates the mounting of the rotating body 21 onto the fixing part 1 through the mounting notch 112. This not only facilitates the assembly of the moving part 2 and the fixing part 1, but also facilitates subsequent disassembly for convenient maintenance of the hinge assembly.

[0047] Reference Figure 4 and Figure 5 The elastic limiting member 3 includes an installation section 31, a bending section 32 and an abutment section 33 connected in sequence. The fixing member 1 is provided with an insertion hole 13 and an assembly port 14. The installation section 31 extends into the insertion hole 13. The bending section 32 is connected to the fixing member 1 and passes through the assembly port 14. The abutment section 33 is provided on a different side from the bending section 32. The abutment section 33 abuts and connects with the movable member 2.

[0048] This configuration not only allows the elastic limiting member 3 to be stably installed on the fixed member 1, ensuring that the elastic limiting member 3 can stably abut against the movable member 2, but also effectively utilizes the structural space of the fixed member 1, improving the structural compactness of the hinge assembly.

[0049] In some embodiments, the abutment section 33 is frame-shaped. This configuration not only makes the structure lightweight but also ensures the contact area with the movable member 2, so that the elastic limiting member 3 can stably provide limiting force to the movable member 2, thereby increasing the reliability of the hinge assembly.

[0050] In some other embodiments, the abutment section 33 is plate-shaped. This arrangement increases the contact area between the abutment section 33 and the movable member 2, thereby further enhancing the limiting force on the movable member 2 and increasing the clamping force between the movable member 2 and the fixed member 1. This helps to improve the effect of controlling the positioning angle between the movable member 2 and the fixed member 1.

[0051] It is understandable that the elastic limiting component 3 can be a torsion spring, a spring sheet, or other structural components with elastic properties, as long as it can provide limiting force for the moving component 2, and no limitation is made here.

[0052] This utility model also proposes a smart glasses, which includes a frame (not shown in the figure), temples (not shown in the figure) and a hinge assembly, which is used to connect the frame and the temples.

[0053] The specific structure of the hinge assembly is as described in the above embodiments. Since the smart glasses adopt all the technical solutions of all the above embodiments, they have at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0054] The frame includes a lens assembly and an optical engine. The lens assembly may include a waveguide sheet and optical lenses, which are stacked together. The waveguide sheet is positioned closer to the face, while the optical lenses are positioned further away. The optical engine can be fixed to the waveguide sheet with adhesive. The optical engine outputs light towards the waveguide sheet and conducts it through the waveguide sheet to form an image that is then transmitted to the user's eyes, thus achieving the display function.

[0055] The optical engine can be a Micro LED optical engine, a Micro OLED optical engine, a DLP optical engine, an Lcos optical engine, or an LBS optical engine. This is just an example and is not intended to be limiting.

[0056] Understandably, the waveguide, optical lens, and optical engine are all in pairs to fully assemble the smart glasses, making them easy for users to use and providing them with a complete user experience.

[0057] The smart glasses may also include an electronic 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 engine, and the battery is electrically connected to the control board. The control board controls the operation of the optical engine, and the battery powers the optical engine. It is understood that the battery is installed in one temple of the smart glasses, and the control board is installed in the other temple, thus completing the overall assembly of the smart glasses.

[0058] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
