Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, and in particular to an AR glasses frame structure and AR glasses. Background Technology

[0002] AR glasses, as an important product in the consumer electronics and smart wearable fields, are widely used in various scenarios such as entertainment, education, and industry due to their augmented reality interactive functions. Their structural design directly affects the user's wearing experience, ease of maintenance, and operating costs, with the connection structure between the temples and the front frame being one of the key components determining the product's practicality.

[0003] Currently, most mainstream AR glasses on the market use a non-detachable structure for the connection between the temples and the lens ring. Specifically, temple a is rigidly connected to lens ring c via a fixed pivot b. The pivot b, lens ring c, and temple a form an inseparable integrated structure; that is, temple a and lens ring c are deeply bound together, making it impossible to separate or detach them individually (e.g., Figure 1 (As shown).

[0004] The existing design has significant drawbacks: Firstly, since the core electronic components of AR glasses (such as motherboards and chips) are mostly integrated inside the temples, when the chip needs to be upgraded to improve performance, users cannot replace the temples separately to complete the upgrade due to the non-removable design of the temples and the front frame. They must replace the entire AR glasses, which greatly increases the cost of use for consumers. Secondly, if the temples or the frame are partially damaged (such as broken temples or worn frames), since the two cannot be separated, users also need to replace the entire device. This not only increases repair costs but also wastes resources and limits users' personalized choices.

[0005] Based on this, the present invention proposes an AR glasses frame structure and AR glasses to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an AR glasses frame structure and AR glasses, enabling convenient assembly and disassembly of the temples and the lens rims.

[0007] To solve the above-mentioned technical problems, this utility model provides an AR glasses frame structure, including a lens rim, temples, a pivot assembly, and a push-button mechanism;

[0008] The head of the mirror ring is provided with an installation groove;

[0009] The pusher mechanism is installed in the mounting slot;

[0010] The rotating shaft assembly is used to realize the rotational connection between the temple and the lens ring. The rotating shaft assembly includes a rotating shaft seat with a mounting hole and a rotating shaft that is detachably inserted and assembled with the mounting hole. The rotating shaft seat and the rotating shaft are respectively connected to the push-button mechanism and the temple.

[0011] When the push-button mechanism is in the locked state, the mounting groove forms a limiting constraint on the rotating shaft to be pulled away from the rotating shaft seat along its axial direction;

[0012] When the pusher mechanism is pressed open, the rotating shaft disengages from the axial limiting area of ​​the mounting groove.

[0013] Furthermore, the push-button mechanism includes a guide rail seat, a drive seat, a compression spring, and a pull hook;

[0014] The drive seat is slidably mounted in the guide rail seat, and the end of the drive seat away from the inner end face of the guide rail seat is connected to the rotating shaft seat;

[0017] The inner wall of the guide rail seat is provided with a guide groove, and the end of the hook away from the drive seat is located in the guide groove. The guide groove is used to guide the hook to switch between the locked state and the released state.

[0018] Furthermore, one side of the guide rail seat has an opening, and a protective cover for sealing the opening is engaged on the guide rail seat.

[0019] Furthermore, the side wall of the guide rail seat is provided with a limiting groove, and a limiting slider is slidably installed in the limiting groove, the limiting slider being connected to the drive seat.

[0020] Furthermore, the rotating shaft is connected to the temple via a limiting guide block;

[0021] The limiting guide block cooperates with the side wall of the mounting groove to form a mechanical stop, thereby limiting the maximum unfolding angle of the temple.

[0022] Furthermore, the rotating shaft is interference-fitted with the mounting hole to provide torque for the opening and closing of the temple.

[0023] Furthermore, the interference fit between the rotating shaft and the mounting hole is 0.03-0.07 mm.

[0024] Furthermore, the temple includes a temple outer shell and a temple inner shell;

[0025] The temple housing is connected to the pivot, and the side wall of the temple housing has an electrical cavity for mounting core electronic components;

[0026] The inner shell of the temple is snapped onto the outer shell of the temple to seal the electrical cavity.

[0027] Furthermore, the lens ring includes a rear lens ring and a front lens ring;

[0028] The rear mirror ring is fitted onto the front mirror ring;

[0029] Both the front and rear mirror rings are provided with U-shaped receiving grooves, and the two receiving grooves together form the mounting groove.

[0030] This utility model also provides an AR glasses, including the AR glasses frame structure described above.

[0031] Compared with the prior art, the present invention has at least the following beneficial effects:

[0032] This invention achieves convenient assembly and disassembly between the temple and the lens frame through the coordinated design of the lens rim, temple, pivot assembly, and push-button mechanism. This allows for performance improvement without replacing the entire device during chip upgrades, simply by replacing the temple, thus reducing upgrade costs for consumers. Furthermore, if the temple or lens rim is partially damaged, the damaged component can be disassembled and replaced individually, avoiding resource waste and increased maintenance costs caused by replacing the entire device.

[0040] The AR glasses frame structure and AR glasses of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0041] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0042] like Figure 1 As shown in the figure, this utility model embodiment proposes an AR glasses frame structure, including a lens rim 1, a temple 2, a pivot assembly 3, and a push-button mechanism 4; the head of the lens rim 1 is provided with a mounting groove 13; the push-button mechanism 4 is installed in the mounting groove 13; the pivot assembly 3 is used to realize the rotational connection between the temple 2 and the lens rim 1, and the pivot assembly 3 includes a pivot seat 31 with a mounting hole and a pivot 32 that is detachably inserted and assembled with the mounting hole; the pivot seat 31 and the pivot 32 are respectively connected to the push-button mechanism 4 and the temple 2.

[0043] like Figure 2 As shown, when the pusher mechanism 4 is in the locked state, the mounting groove 13 forms a limiting constraint on the rotating shaft 32 to pull it away from the rotating shaft seat 31 along its axial direction.

[0044] like Figure 3 As shown, when the pusher mechanism 4 is pressed open, the rotating shaft 32 disengages from the axial limiting area of ​​the mounting groove 13.

[0045] In this embodiment, through the collaborative design of the lens ring 1, temple 2, pivot assembly 3, and push-button mechanism 4, a highly efficient solution for quick temple disassembly is formed: the mounting groove 13 at the head of the lens ring 1 provides the mounting base for the push-button mechanism 4; the pivot seat 31 and pivot 32 of the pivot assembly 3 are detachably connected to achieve the rotational connection between the temple 2 and the lens ring 1; and the push-button mechanism 4 achieves stable connection and quick separation of the temple 2 by switching between locked and unlocked states and using the axial limit control of the pivot by the mounting groove 13.

[0046] In summary, the AR glasses frame structure provided by this utility model achieves convenient assembly and disassembly between the temple 2 and the temple 1 through the coordinated design of the lens ring 1, temple 2, pivot assembly 3, and push-button mechanism 4. This allows for performance improvement by replacing only the temple 2 during chip upgrades without replacing the entire device, thus reducing upgrade costs for consumers. At the same time, if the temple 2 or the temple 1 is partially damaged, the damaged part can be disassembled and replaced separately, avoiding the waste of resources and increased maintenance costs caused by replacing the entire device.

[0047] In the above embodiments, specifically, in conjunction with reference to... Figure 4 The push-button mechanism 4 includes a guide rail seat 41, a drive seat 42, a compression spring 43, and a pull hook 44. The drive seat 42 is slidably installed in the guide rail seat 41, and one end of the drive seat 42 away from the inner end face of the guide rail seat 41 is connected to the rotating shaft seat 31. The compression spring 43 is installed between the inner end face of the guide rail seat 41 and the drive seat 42. The pull hook 44 is Z-shaped, and one end of the pull hook 44 is rotatably connected to the drive seat 42. A guide groove 411 is provided on the inner side wall of the guide rail seat 41, and one end of the pull hook 44 away from the drive seat 42 is located in the guide groove 411. The guide groove 411 is used to guide the pull hook 44 to switch between a locked state and a pop-out state.

[0048] In the above embodiment, specifically, the guide groove 411 is a continuous groove trajectory, which is divided into two segments, including a V-shaped guide segment and a Y-shaped branch segment. It should be noted that the specific trajectory characteristics of the guide groove 411 belong to the prior art and will not be described in detail here.

[0049] The locking and unlocking of the push-button mechanism 4 are achieved through the arrangement of the guide rail 41, drive seat 42, compression spring 43, pull hook 44, and guide groove 411, by means of a "push-push" action logic. The specific process is as follows:

[0050] (1) Locked state (initial state)

[0051] In the locked state, the positions and coordination relationships of the components of the trigger mechanism 4 are as follows:

[0052] The engagement of the hook 44 with the guide groove 411: The hook 44 is Z-shaped, with its end furthest from the drive seat 42 engaging in the locking position of the guide groove 411, such as... Figure 5 As shown. At this time, under the constraint of its own shape and the locking position of the guide groove 411, the hook 44 forms an axial limit on the drive seat 42, preventing the drive seat 42 from moving outward (away from the inner end face of the guide seat 41) along the axial direction of the guide seat 42.

[0053] The state of the compression spring 43: The compression spring 43 is in a naturally stretched state (or slightly stretched state), with one end fixed to the inner end face of the guide rail seat 41 and the other end connected to the drive seat 42, and its elastic force pointing towards the drive seat 42.

[0054] Position of drive seat 42 and pivot seat 31: The drive seat 42 is located inside the sliding cavity of the guide rail seat 41, and the pivot seat 31 connected to the end of the drive seat 42 away from the inner end face of the guide rail seat 41 is in a retracted state.

[0055] Limiting function of the rotating shaft: At this time, the inner wall of the mounting groove 13 of the head of the lens ring 1 is in contact with the end of the rotating shaft 32. Under the premise that the pull hook 44 locks the drive seat 42, the mounting groove 13 restricts the rotating shaft 32 from being pulled away from the rotating shaft seat 31 along its axis by axially constraining the rotating shaft 32, thereby realizing a stable connection between the temple 2 and the lens ring 1, ensuring that it will not fall off accidentally during daily wear or when the temple is opened or closed.

[0056] (2) Pop-out state (triggering disassembly process)

[0057] When it is necessary to remove the temple, press the end of the temple 2 near the lens rim 1 (or directly press the force-bearing part associated with the drive seat) to trigger the pop-out state. The specific process is as follows:

[0058] Pressing trigger and force transmission: External force presses the mirror arm 2 along the axial direction of the guide rail seat 41 inward (pointing to the inner end face of the guide rail seat). The force is transmitted to the drive seat 42 through the rotating shaft 32 and the rotating shaft seat 31, causing the drive seat 42 to move inward along the sliding cavity of the guide rail seat 41.

[0059] Movement of compression spring 43 and hook 44: When the drive seat moves inward, it will compress the compression spring 43; at the same time, the hook 44 moves inward synchronously with the drive seat 42, and its end away from the drive seat 42 slides from the locked position to the transition section along the guide groove 411.

[0060] The key action for state switching: When pressed to the limit position (drive seat moves to the innermost side), the end of the hook 44 is released from the recessed constraint of the locking position of the guide groove 411. Under the slight radial offset of the drive seat 42, it slides into the spring-open position of the guide groove 42. At this time, the axial limit of the hook 44 on the drive seat 42 is released.

[0061] Reset and Limit Release: The compression spring 43 releases its stored elastic potential energy, pushing the drive seat 42 to pop out rapidly along the axial direction of the guide rail seat 41 (away from the inner end face of the guide rail seat); the drive seat 42 drives the rotating shaft seat 31 to move outward synchronously, and the end of the hook 44 slides along the guide groove 411 to the pop-out position and remains stable, such as Figure 6 As shown.

[0062] Release of constraint on pivot 32: As pivot seat 31 pops outward, pivot 32 moves synchronously with pivot seat 31, and its end is removed from the axial constraint area of ​​the inner wall of mounting groove 13. The axial removal limit of mounting groove 13 on pivot 32 is released. At this time, the temple 2 can be directly removed from the mounting hole of pivot seat 31 along the axial direction of pivot 32 to achieve quick disassembly.

[0063] Through the above process, the push-button mechanism 4, with the help of the guide groove 411, the hook 44 and the compression spring 43, achieves a precise switch of "one press to lock, two press to release". This ensures a stable connection between the temple 2 and the lens rim 1 during daily use, and allows the constraint to be released with a simple pressing action, meeting the need for quick disassembly.

[0064] Furthermore, the guide rail seat 41 has an opening on one side, and a protective cover 45 for sealing the opening is engaged on the guide rail seat 41. The removable protective cover 45 facilitates the maintenance and replacement of components installed inside the guide rail seat 41; preferably, the protective cover 45 is made of metal, such as stainless steel or aluminum alloy, to ensure good stability of the push button mechanism 4.

[0065] Furthermore, a limiting groove 412 is provided on the side wall of the guide rail seat 41, and a limiting slider 421 is slidably installed in the limiting groove 412. The limiting slider 421 is connected to the drive seat 42. The limiting slider 421 and the limiting groove 412 provide sliding guidance for the drive seat 42, thereby improving the stability of the operation of the pusher mechanism 4.

[0066] Furthermore, the rotating shaft 32 is connected to the temple 2 via a limiting guide block 321. The limiting guide block 321 cooperates with the side wall of the mounting groove 13 to form a mechanical stop, thereby limiting the maximum unfolding angle of the temple 2.

[0067] Furthermore, the pivot 32 is interference-fitted with the mounting hole to provide torque for the opening and closing of the temple 2. To ensure effective damping and avoid excessive damping affecting disassembly, the interference between the pivot 32 and the mounting hole is 0.03-0.07mm, preferably 0.05mm.

[0068] In the above embodiment, the temple 2 includes a temple outer shell 21 and a temple inner shell 22; the temple outer shell 21 is connected to the pivot 32, and the side wall of the temple outer shell 21 has an electrical cavity for installing core electronic components; the temple inner shell 22 is snapped onto the temple outer shell 21 to seal the electrical cavity.

[0069] In this embodiment, the inner temple shell 22 provides physical protection for the core electronic components, preventing dust, foreign objects from entering or external impacts from damaging the components and ensuring their stable operation. At the same time, the inner temple shell 22 is connected to the outer temple shell 21 by a snap-fit ​​method, which is convenient for disassembly and assembly and facilitates the maintenance of the core electronic components.

[0070] In the above embodiment, the lens ring 1 includes a rear lens ring 11 and a front lens ring 12; the rear lens ring 11 is snapped onto the front lens ring 12; both the front lens ring 12 and the rear lens ring 11 are provided with a receiving groove with a "U" shaped cross section, and the two receiving grooves together form the mounting groove 13.

[0071] In this embodiment, the lens ring 1 adopts a design of separate snap-fit ​​rear lens ring 11 and front lens ring 12, which effectively facilitates the disassembly and assembly of the trigger mechanism 4 and makes it easier for the trigger mechanism 4 to be maintained and replaced later.

[0072] This utility model embodiment also provides an AR glasses, including the AR glasses frame structure described above.

[0073] In this embodiment, the coordinated design of the lens ring 1, temple 2, pivot assembly 3, and push-button mechanism 4 enables convenient disassembly and assembly between the temple 2 and the lens ring 1. This allows for performance improvement by simply replacing the temple 2 during chip upgrades without replacing the entire device, thus reducing upgrade costs for consumers. Furthermore, if the temple 2 or lens ring 1 is partially damaged, the damaged component can be disassembled and replaced individually, avoiding resource waste and increased maintenance costs caused by replacing the entire device.

[0074] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
