Description

Technical Field

[0001] The present invention relates to a frame structure, and in particular to a frame structure of AR glasses. Background Art

[0002] Augmented reality (AR) technology has developed rapidly in recent years. AR glasses, as a key hardware platform, are widely used in various fields such as industry, healthcare, education, and entertainment. AR glasses need to accurately overlay virtual information with real scenes, which places high demands on the stability and comfort of the device.

[0003] Traditional temples have fixed lengths or a limited adjustment range, making them difficult to adapt to different head shapes and user preferences. Temples that are too short or too long can lead to instability or a sense of pressure, affecting comfort during extended use. This is especially true for AR applications that require precise information display. Insufficient stability can severely impact user experience and operational accuracy. Most glasses have non-adjustable or difficult-to-adjust nose pads, making them unable to accommodate the varying widths and heights of different users' noses. Improper nose pad placement can easily cause glasses to slide down, compress the nose bridge, or affect the alignment of the optical module, reducing not only wearing comfort but also the clarity and accuracy of virtual information displayed.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] The embodiments of the present invention are as follows:

[0027] like Figure 1 and Figure 2 As shown, the frame structure of the AR glasses of the present invention includes a lens frame 1, a length adjustment mechanism and a spacing adjustment mechanism. The lens frame 1 is used to support and dissipate heat of the overall frame structure; the length adjustment mechanism is installed on both symmetrical sides of the lens frame 1 and is used for multi-stage adjustment of the length of the temple 7; the spacing adjustment mechanism is installed at the bottom of the lens frame 1 and is used for adaptive adjustment of the position of the nose pad 15.

[0028] like Figure 3 and Figure 4 As shown, the length adjustment mechanism includes two adjustable temples 7, and side mounting grooves 3 for installing the two temples 7 are symmetrically opened at both ends of the mirror body frame 1. A stabilizing portion and a locking structure are provided in each side mounting groove 3. Each temple 7 includes a splicing block 4, a connecting plate 5 and a movable plate 6 that are plugged in and vertically arranged in sequence. The front part of the splicing block 4 is plugged into the side mounting groove 3 through the stabilizing portion and locked by the locking structure. The front part of the connecting plate 5 is plugged into the slot opened at the rear part of the splicing block 4, and the front part of the movable plate 6 is plugged into the slot opened at the rear part of the connecting plate 5. The rear part of the movable plate 6 serves as a leg cover for the ear hook and is provided with a hollow groove.

[0029] The stabilizing portion includes two stabilizing shafts 31 arranged at intervals, and the two stabilizing shafts 31 are parallel to the direction of the temples 7. Two stabilizing straight holes 32 are provided in the front section of the splicing block 4, and a blind hole 44 is provided at the top of the splicing block 4. A vertical first through hole is provided on the mirror body frame 1 directly above the side mounting groove 3. When the front part of the splicing block 4 is inserted into the side mounting groove 3, the two stabilizing shafts 31 are inserted into the two stabilizing straight holes 32, and the first through hole and the blind hole 44 are opposite and locked by a locking structure.

[0030] The locking structure includes an insert shaft 41, a top plate 42, and a spring 43. The top plate 42 is arranged horizontally. The upper end of the insert shaft 41 is connected to the center of the bottom surface of the top plate 42 and is integrally formed. The spring 43 is sleeved on the insert shaft 41. The upper and lower ends of the spring 43 are respectively connected to the bottom surface of the top plate 42 and the top surface of the first through hole. The lower end of the insert shaft 41 passes through the first through hole and is inserted into the blind hole 44 of the splicing block 4 to lock the position of the splicing block 4. When the top plate 42 is manually pulled up, the insert shaft 41 can be moved away from the blocking position of the splicing block 4 to facilitate the insertion of the splicing block 4. After insertion, the position of the blind hole 44 corresponds to the first through hole opened on the mirror body frame 1. At this time, the hand releases the top plate 42, and under the action of the spring 43, the insert shaft 41 is driven to reset and move downward through the first through hole to be inserted into the blind hole 44 to lock the position of the splicing block 4.

[0031] A second through hole is horizontally opened on the side of the slot of the connecting plate 5, and a plurality of spaced locking holes 8 are also horizontally opened on the front of the movable plate 6. The connecting direction of each locking hole 8 is parallel to the direction of the temple 7. When the movable plate 6 is inserted into the connecting plate 5, when one of the locking holes 8 is facing the second through hole, the position of the movable plate 6 is locked by inserting the locking screw 9 into the lock hole 8 through the second through hole.

[0032] The bottom surface of the mirror body frame 1 is provided with a mounting groove 10, and the spacing adjustment mechanism is installed in the mounting groove 10; the spacing adjustment mechanism includes a bidirectional screw 11, a knob 12 and two mounting blocks 13, the bidirectional screw 11 is horizontally installed in the mounting groove 10, and a third through hole is provided on the side of the mirror body frame 1 on one side of the mounting groove 10. The third through hole is located directly below the side mounting groove 3, and the knob 12 passes through the third through hole and is synchronously connected to one end of the bidirectional screw 11. The other end of the bidirectional screw 11 does not have a threaded portion and is connected to the inner wall of the mounting groove 10. Rotational connection, two mounting blocks 13 are threadedly mounted on both sides of the bidirectional lead screw 11, and the side surfaces of the mounting blocks 13 are in contact with the side surfaces of the mounting groove 10; each nose pad 15 is connected to its own mounting block 13 through a bent connecting rod 14, the mounting block 13 and the bent connecting rod 14 are integrally formed, and the nose pad 15 has a hollow groove; the knob 12 is made of lightweight material and the outer wall is provided with an anti-slip groove, which is convenient for manual operation. The position of the nose pad 15 can be adjusted according to the user's needs, and the hollow groove can reduce the wearing pressure.

[0033] like Figure 5 As shown, bell mouths 16 are further provided on both symmetrical sides of the bottom of the mirror body frame 1. The bell mouths 16 are located on one side of the third through hole and directly below the side mounting groove 3. An inclined air duct 161 is provided from the bell mouth 16 to the bottom of the mirror body frame 1. Directly above each air duct 161, a plurality of inclined holes 17 arranged at intervals are connected to the inner bottom surface of the mirror body frame 1, and then connected to the interior of the mirror body frame 1 to ventilate and prevent the generation of aerosol when the user wears it.

[0034] An arc groove 101 is provided on the upper side of the rear portion of the mirror body frame 1 to adapt to the structure of the human face, and two lens mounting grooves 2 for mounting lenses are symmetrically provided on the front portion of the mirror body frame 1.

[0035] The working principle of the present invention is as follows:

[0036] The temple 7 is integrally formed with the front end of the movable plate 6. The movable plate 6 is inserted into the slot at the front end of the splicing block 4, forming a sliding fit. To adjust the extension length of the temple 7, the user first loosens the locking screw 9 on the side of the movable plate 6, disengaging the end of the temple from a lock hole 8 on the side of the movable plate 6. The user can then push and pull the movable plate 6 along the slot to adjust it to the desired position. Once adjusted, the user tightens the locking screw 9 so that the extended end precisely inserts into the corresponding lock hole 8 on the side of the movable plate 6. The combination of the lock hole 8 and the locking screw 9 forms a rigid constraint, preventing the movable plate 6 from moving within the slot, thereby firmly locking the temple 7 at the set length. The locking holes 8 in different positions provide multiple adjustable fixing points. To install or remove the temple assembly (including the splicing block 4, connecting plate 5, and movable plate 6), the user pulls upward on the top plate 42 on the mirror frame 1. The upward movement of the top plate 42 drives the connected insertion shaft 41 upward, overcoming the elastic force of the spring 43, causing its lower end to exit the blind hole 44 on the upper surface of the splicing block 4, thereby releasing the lock on the splicing block 4. During installation, the stabilizing straight hole 32 on the rear side of the splicing block 4 is aligned with the stabilizing shaft 31 in the side mounting groove 3. The splicing block 4 is pushed horizontally along the stabilizing shaft 31 until it is fully inserted into the side mounting groove 3. When the splicing block 4 is pushed into place, the blind hole 44 on it is aligned with the through hole in the mirror frame 1. At this time, the user releases the top plate 42. Under the restoring force of the spring 43, the insertion shaft 41 is pushed downward, passes through the through hole of the mirror frame 1, and is precisely inserted into the blind hole 44 of the splicing block 4.The insertion of the plug shaft 41 into the blind hole 44 forms a reliable mechanical lock, which firmly fixes the splicing block 4 (together with the entire temple assembly) on the mirror body frame 1. The cooperation of the stabilizing shaft 31 and the stabilizing straight hole 32 ensures the accuracy of the installation position and the initial stability of the splicing block 4. When disassembling, pull up the top plate 42 and pull the splicing block 4 horizontally along the stabilizing shaft 31 to remove it from the side mounting groove 3; the adjustment of the spacing between the nose pads 15 is done by manually operating the knob 12. The rotation of the knob 12 drives the bidirectional screw 11 to rotate synchronously. The left and right sections of the bidirectional screw 11 have threads in opposite directions. A nose pad 15 is fixedly connected to the bottom of each mounting block 13 by a bent connecting rod 14. Therefore, the synchronous movement of the mounting blocks 13 toward or away from each other directly drives the two nose pads 15 to move equidistantly closer or farther away, thereby realizing the nose pads 15 The spacing can be adjusted steplessly. An air duct 161 is provided inside the bottom of the mirror body frame 1, and the outer opening is designed as a trumpet 16. When the user wears glasses and moves (such as walking, turning the head) or there is natural wind in the environment, the airflow is more easily captured by the trumpet 16 and introduced into the air duct 161. The introduced airflow flows through the air duct and enters or flows out of the internal space of the frame through the inclined hole 17. The flowing air exchanges heat with the hot air accumulated inside the frame and the surface of the heating components, that is, convection heat dissipation, and brings the heat out of the mirror body frame 1. The design of the inclined hole 17 helps to optimize the airflow path, improve the heat dissipation efficiency, effectively reduce the internal temperature, prevent overheating and fogging of the lenses, and the hollow grooves in the components directly reduce the material usage while ensuring the structural rigidity and strength, thereby reducing the weight of these components and even the overall weight.
