Description

Technical Field

[0001] This utility model relates to the field of augmented reality technology, and in particular to a shockproof AR glasses. Background Technology

[0002] As smart glasses become increasingly feature-rich and sophisticated, their improved wearing experience and reduced battery anxiety make their widespread adoption a natural progression. Currently, smart glasses lenses are almost entirely made of fragile materials like glass, and due to considerations such as weight reduction, the likely trend is for lenses to become thinner and more fragile.

[0003] Due to the inherent characteristics of smart glasses—the display device (lens) and image output unit (optical engine) are concentrated in the front part of the glasses or near the forehead—the center of gravity is biased towards the front. If the glasses fall from the bridge of the nose or from a height, the front part, being the heavier component, will generally hit the ground first. Combined with the thinness of the glass lenses, they are easily shattered. While the temples provide cushioning protection at the rear of the glasses during a fall, the front, apart from a thin structural element, offers no other protection. On one hand, even a slightly larger protruding hard object can shatter the glass lenses; on the other hand, a direct impact without cushioning can shatter or damage other components of the glasses.

[0031] Example

[0032] according to Figures 1-3 This embodiment provides a drop-proof AR glasses, including:

[0033] The frame includes a temple 10, a frame 20 connected to the temple 10, and an AR lens 50 mounted on the frame 20. The frame 20 includes a main frame surface, and at least a portion of the main frame surface is provided with an arcuate groove 21.

[0034] The anti-fall component includes at least a U-shaped ejector 30, a locking element 31, and a driving element. The two ends of the U-shaped ejector 30 are connected to the two side walls of the arc-shaped groove 21 by elastic members 60, and the U-shaped ejector 30 and the arc-shaped groove 21 are adapted in size. The locking element 31 is located at the opposite end of the frame 20. The locking element 31 includes an extension end and a bottom end. The extension end is provided with a slot 33, and the bottom end is provided with a sliding groove 34. The slot 33 can engage the U-shaped ejector 30 and lock the U-shaped ejector 30 in the arc-shaped groove 21. The sliding groove 34 is provided with a protrusion, and the inner wall of the sliding groove 34 is provided with a concave hole adapted to the protrusion. The protrusion passes through the concave hole, and the locking element 31 slides guided by the protrusion. The driving element includes at least a cam 40, which is located near the locking element 31.

[0035] The controller is electrically connected to the locking element 31 and the drive element. The controller is configured to start the cam 40 to rotate, push the locking element 31 away from the arc groove 21 to slide, so that the U-shaped ejector 30 ejects from the arc groove 21 and the U-shaped ejector 30 is perpendicular to the main frame surface.

[0036] This embodiment presents a drop-proof AR glasses, including a frame 20, temples 10, and AR lenses 50. Both symmetrical frames 20 are equipped with drop-proof components. The drop-proof components include a U-shaped pop-out bracket 30, a locking mechanism 31, and a driving mechanism that work together to allow the U-shaped pop-out bracket 30 to retract and quickly deploy. During normal wear, the U-shaped pop-out bracket 30 is retracted and fixed within the arc-shaped groove 21 of the frame 20 via the locking mechanism 31, without affecting the daily use and wearing comfort of the glasses. If the glasses are accidentally dropped, the driving mechanism triggers the locking mechanism 31 to release the U-shaped pop-out bracket 30, forming a buffer zone. This buffer zone absorbs some of the impact force, reducing the force directly acting on the AR lenses 50, thereby protecting the AR lenses 50 and other important components from or mitigating damage. This design not only improves the durability of the glasses but also extends their lifespan, especially in unstable environments, providing users with greater safety.

[0037] The anti-fall AR glasses proposed in this embodiment include a controller. When the controller receives a signal that the anti-fall AR glasses are in free fall, the controller will respond quickly and start the drive to drive the cam 40 to rotate, thereby pushing open the locking buckle 31. This series of actions allows the U-shaped pop-out bracket 30 embedded in the arc groove 21 of the front frame 20 of the AR glasses to pop out, forming a buffer structure to protect the internal lenses and other key components from hard impacts and wear.

[0038] Furthermore, the drop-proof AR glasses also include a drop sensor device to detect whether the device is in a freefall state. This sensor is designed to promptly identify and take appropriate protective measures when the glasses are about to fall to the ground, reducing or preventing damage to the device. The drop sensor works based on infrared emission and reception technology. An algorithm identifies whether the AR glasses are in a freefall state. For example, when the device is placed or used normally, the infrared emitter emits infrared light towards the ground, and the infrared receiver receives this light. If the device is not falling, the infrared light can be successfully reflected back to the receiver, and the sensor detects a normal signal. Once the device begins to fall freely, the infrared light is interrupted because the distance between the device and the ground increases rapidly, causing the infrared light to be unable to be reflected back to the receiver. At this time, the receiver detects a signal loss, and the algorithm identifies that the device is in a freefall state. In this embodiment, the algorithm is not specifically limited, as long as it can identify the freefall state. The drop sensor device is installed at the bottom of the AR glasses, i.e., the part that first contacts the ground. The specific location is selected and set based on a comprehensive consideration of the appearance design, weight, and other factors of each actual drop-proof AR glasses model. Other detection devices or systems can also be used to achieve the above functions, and no specific limitations are made in this embodiment.

[0039] The temples 10, the frame 20 connected to the temples 10, and the AR lens 50 mounted on the frame 20 mentioned in this embodiment are specifically anti-drop AR glasses designed to adapt to the structure of the human eye. The frame 20 in this embodiment includes a left frame 20 and a right frame 20. Preferably, the main frame surface is U-shaped, meaning the surface of the frame 20 furthest from the temples 10 is the main frame surface. Both the left and right frames 20 are U-shaped, and are connected by a nose bridge. Preferably, the frame 20 and the nose bridge are an integrated structure. AR lenses 50 are fixedly installed inside both the left and right frames 20, that is, the AR lens 50 is installed in the central area of ​​the U-shaped frame for displaying augmented reality content. The AR lens 50 can use light waves... Using optical technologies such as guides, diffraction gratings, or others to achieve transparent display and maintain good light transmittance, the left and right temples 10 are rotatably connected to the ends of the frame 20 on both sides, responsible for supporting the glasses and adjusting them to fit the wearer's head. Preferably, a left arc-shaped groove 21 and a right arc-shaped groove 21 are provided on the left and right frames 20 at the front of the anti-drop AR glasses, surrounding the AR lens 50 area. The left arc-shaped groove 21 is located near the left temple 10 and is used to place the left U-shaped ejector bracket 30 of the anti-drop component. The right arc-shaped groove 21 is located near the right temple 10 and is used to place the right U-shaped ejector bracket 30 of the anti-drop component. This facilitates the daily use of the anti-drop AR glasses, enhances the durability of the AR glasses, and provides additional protection in the event of an accidental drop.

[0040] Furthermore, it also includes anti-drop components, including at least a U-shaped ejector 30, a locking element 31, and a driving element. In this embodiment, the U-shaped ejector 30 includes a left U-shaped ejector 30 and a right U-shaped ejector 30. The two ends of the U-shaped ejector 30 are connected to the side walls of the arc-shaped groove 21 by elastic members 60. Preferably, the two ends of the arc-shaped groove 21 are located at opposite upper and lower positions of the frame 20, and pivot screws 62 are provided at the side walls of the arc-shaped groove 21. Torque members 61 are provided at both ends of the U-shaped ejector 30. The torsion members pass through the pivot screws 62 and abut against the bottom of the arc-shaped groove 21. The design of the torsion members 61 allows them to abut against the bottom of the arc-shaped groove 21, thereby producing the effect of ejecting the U-shaped ejector 30. The torsion members 61 are usually some kind of elastic... Metal components, such as springs or elastic elements, need to be tightly fitted with the pivot screw 62 to generate rotational movement when subjected to external forces. For example, a torsion spring needs to pass through the pivot screw 62 and press against the bottom of the arc-shaped groove 21. This method utilizes the elastic properties of the torsion spring. When the torsion spring is twisted, it applies an outward force, pushing the U-shaped ejector 30 outward along the arc-shaped groove 21. Preferably, the U-shaped ejector 30 and the arc-shaped groove 21 are matched in size, both being U-shaped. The ejected U-shaped ejector 30 can be perpendicular to the frame 20, ensuring that the U-shaped ejector 30 can reliably eject when needed, while maximizing the protection of the entire AR lens 50 from external damage. See Figure 2 Preferably, the U-shaped ejector frame 30 is made of carbon steel, which has good strength and durability and can effectively resist external impacts and wear.

[0041] In this embodiment, the locking fastener 31 includes a left locking fastener 31 and a right locking fastener 31. Locking fasteners 31 are provided at opposite ends of the frame 20. Specifically, the left locking fastener 31 is located at the end of the left frame 20 near the left temple 10, and the right locking fastener 31 is located at the end of the right frame 20 near the right temple 10. Each locking fastener 31 includes an extension end and a bottom end. The extension end has a slot 33, and the bottom end has a sliding groove 34. The shape of the slot 33 is adapted to the U-shaped ejector bracket 30, allowing it to securely engage with the U-shaped ejector bracket 30 and lock it within the arc-shaped groove 21. A protruding post is located within the sliding groove 34, and a recessed hole adapted to the protruding post is located on the inner wall of the sliding groove 34. The protruding post passes through the recessed hole, forming a locking mechanism for a more stable locking effect. Figure 1Simultaneously, it can be easily unlocked when needed. Unlocking requires the activation of a driving component, which includes at least a cam 40 and a cam motor 41. The cam 40 is positioned near the locking element 31, and its shaft is connected to one end of the cam motor 41. The cam motor 41 can drive the cam 40 to rotate. When the cam 40 rotates, since the locking element 31 also includes a pushing end 32, and the cam 40 is positioned near the pushing end 32, the cam 40 can push the locking element 31 to slide with a protruding guide, completing the separation of the slot 33 from the U-shaped ejector 30, thereby realizing the unlocking function. See Figures 2-3 The anti-drop component proposed in this embodiment makes the use of the U-shaped pop-out frame 30 more flexible and controllable, and is suitable for scenarios that require rapid deployment and retraction.

[0042] according to Figure 3 The bottom end and the extension end are connected to form an L-shape, or it can be similar to a Z-shape. In this embodiment, there is no specific limitation, as long as it satisfies the requirement of locking the U-shaped ejector 30 and being able to unlock and eject the U-shaped ejector 30 in time when it is started. There is at least one locking fastener 31. Dividing the area of ​​the frame 20 near the temple 10 into a middle area and two end areas, the locking fastener 31 can be one, set in the middle area. A single locking fastener 31 is the simplest to operate and meets the basic locking and releasing requirements. Alternatively, there can be two locking fasteners 31, set in the two end areas. Or there can be three locking fasteners 31, with one locking fastener 31 in the middle area and one locking fastener 31 in each of the two end areas, which can provide better structural stability and reduce deformation and loosening under external force.

[0043] The anti-fall component also includes a reset element 35, which consists of a magnet and a magnetic sheet. The magnetic sheet is preferably located between the lower end and the extended end of the locking element 31. The magnet is located on the frame 20 and is positioned corresponding to the magnetic sheet. This method uses the attraction of magnetic force to achieve the reset function of the locking element 31. When the locking element 31 is subjected to the external force of the cam 40, it opens and pops out the U-shaped ejector 30. After the external force of the cam 40 is released, the magnetic force between the magnet and the magnetic sheet will cause the locking element 31 to automatically return to the initial state. This reset mechanism is simple and reliable. By utilizing the characteristics of magnetic force, a fast and stable reset can be achieved.

[0044] The above provides a detailed description of a drop-proof AR glasses embodiment of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
