Description

Technical Field

[0001] This invention relates to the field of AR smart glasses technology, and more particularly to a wearable head-mounted AR smart glasses device. Background Technology

[0002] AR smart glasses are a new type of tool that integrates augmented reality technology with smart wearable devices, enabling virtual information to be overlaid onto the real world and achieve virtual-real interaction. Through real-time spatial positioning, AR glasses can accurately identify the user's environment and seamlessly integrate digital content with the physical world, creating an intuitive and immersive experience.

[0003] AR smart glasses have already demonstrated their value in fields such as industry, healthcare, and education. For example, engineers use the glasses to view equipment maintenance instructions, improving work efficiency; doctors can access patient image data in real time during surgery, enhancing operational accuracy; in educational settings, 3D models help students understand complex knowledge; and on the consumer side, the focus is on entertainment and daily information prompts. With technological advancements and a more complete ecosystem, AR glasses are expected to gradually expand from enterprise tools to mass-market smart terminals, becoming the next-generation interactive interface after mobile phones.

[0004] The distance between the support rods of current AR smart glasses is relatively fixed, which limits their applicability and affects the comfort of the user. For example, people with larger faces experience greater pressure on the support rods, while people with smaller faces experience less pressure, affecting the stability of the device. In addition, there is uneven weight distribution, resulting in greater pressure on the bridge of the nose and shorter battery life. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of limited applicability, poor comfort, low stability, and short battery life of existing AR smart glasses, and to propose a wearable head-mounted AR smart glasses device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wearable head-mounted AR smart glasses device includes a support frame and further includes: an extension seat symmetrically arranged inside the support frame, with a pitch-changing mechanism between the extension seat and the support frame, and a support rod rotatably connected to the end of the extension seat; a control component between the extension seat and the support rod for controlling the movement direction of the extension seat; an infrared sensor symmetrically fixedly connected to the side of the support frame near the support rod; an adjustment component symmetrically arranged at the bottom of the support frame, electrically connected to the infrared sensor; and battery compartments symmetrically fixedly connected to the support rod, with a strap between the two battery compartments; and a tensioning mechanism on the side of the battery compartment near the strap for adjusting the size of the strap.

[0008] To better accommodate users with different face sizes, the variable pitch mechanism preferably includes symmetrically arranged storage slots at both ends of the support frame. The extension seat is slidably connected inside the storage slots. A micro motor is fixedly connected to the side of the support frame near the storage slots. A screw is fixedly connected to the output end of the micro motor. A threaded hole matching the screw is opened inside the extension seat. A compression rod is fixedly connected between the storage slots and the extension seat.

[0009] To facilitate adjustment of the dimensions between the support rods, the control assembly further includes a groove formed on the side of the extension seat near the support rod. An electromagnet is fixedly connected inside the groove, and a second spring is fixedly connected to the electromagnet. A permanent magnet is fixedly connected to the end of the second spring. A movable plate is fixedly connected to the side of the permanent magnet away from the second spring. A fixed plate is fixedly connected to the side of the extension seat near the support rod and away from the groove. When the electromagnet is energized, the electromagnet and the permanent magnet have the same magnetism on the side closest to each other. The permanent magnet and the fixed plate are slidably connected to the groove.

[0010] To further improve the stability of the support rod during use, it also includes a mounting groove formed on the side of the movable plate and the fixed plate close to each other. Multiple sets of third springs are fixedly connected inside the mounting groove. The ends of the third springs are fixedly connected to pressure blocks that are slidably connected to the mounting groove. Control switches are fixedly connected on the side of the mounting groove close to the pressure blocks. Two sets of control switches are electrically connected to the micro motor, and the two sets of control switches are used to control the forward and reverse rotation of the micro motor, respectively.

[0011] To further reduce the size of the device when not in use, a limiting groove is also included on the side of the extension seat near the groove. When the movable plate moves into the groove, the pressure block moves into the limiting groove.

[0012] To facilitate adjustment of the distance between the lenses and improve the device's performance, the adjustment assembly further includes symmetrically arranged grooves at the bottom of the support frame. A slide block is slidably connected inside the grooves. An adjustment rod is fixedly connected inside the support frame and to the slide block. A first spring is fixedly connected between the slide block and the groove. The support frame has a temporary storage cavity connected to the compression rod. The temporary storage cavity is connected to the adjustment rod via a pressure relief valve, a solenoid valve, and a pipe. The solenoid valve and the pressure relief valve are electrically connected to an infrared sensor. An imaging assembly is mounted on the slide block.

[0013] To facilitate the overlay of virtual information onto the real world, the imaging component further includes a frame fixedly connected to a slide, with a lens fixedly connected to the frame, the lens being used to overlay virtual information onto the real field of vision.

[0014] To ensure the cleanliness of the lenses before use and to remove water mist generated during use, the system further includes an air inlet between the slide and the frame. The bottom of the frame has a drain outlet, and the bottom of the storage slot has a hole that communicates with the air inlet. The hole is connected to the temporary storage chamber via a solenoid valve and a pipe. The exhaust end of the pressure relief valve is connected to the hole at the bottom of the storage slot via a pipe.

[0015] To reduce pressure on the ears and improve the device's battery life, the tightening mechanism further includes a guide groove within the battery compartment. The strap is slidably connected to the guide groove. An installation cavity communicating with the guide groove is located inside the battery compartment. A micro motor is installed inside the installation cavity. A rotating shaft is fixedly connected to the output end of the micro motor. A guide wheel that fits with the strap is fixedly connected to the rotating shaft. An installation roller is fixedly connected to the rotating shaft. Multiple sets of rotating bars are fixedly connected to the outer wall of the installation roller. A compressed air rod matching the rotating bars is fixedly connected to the inner wall of the installation cavity. The micro motor inside the installation cavity is electrically connected to the micro motor inside the support frame. The two sides of the rotating bar's end are inclined. The compressed air rod is elastic and has an arc-shaped end. The compressed air rod is connected to the temporary storage cavity via a pipe.

[0016] To ensure the stability of the device during use, preferably, it also includes an ear hook fixedly connected to the end of the support rod away from the support frame. The ear hook is arc-shaped and is used to hang the device on the ear.

[0017] Compared with the prior art, the present invention provides a wearable head-mounted AR smart glasses device with the following advantages:

[0018] 1. This wearable head-mounted AR smart glasses device can drive a variable distance mechanism through a control component to adjust the distance between two sets of support rods to accommodate users with different face sizes, thereby increasing the device's applicability, user comfort, and stability during use.

[0019] 2. This wearable head-mounted AR smart glasses device uses an infrared sensor to drive the adjustment component, thereby adjusting the distance between the two sets of lenses to suit users with different eye distances. At the same time, when water fog appears on the lens surface, it treats the water fog, thereby improving the user's viewing experience.

[0020] 3. This wearable head-mounted AR smart glasses device increases battery life through its battery compartment design, and reduces pressure on the ears and bridge of the nose through straps and elastic mechanisms, further improving device comfort. In addition, it also improves the stability of the device during use.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention can overcome the problems of limited applicability, poor comfort, low stability, and short battery life of AR smart glasses. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Example 1:

[0033] Reference Figures 1-7 A wearable head-mounted AR smart glasses device includes a support frame 1, and further includes: an extension seat 3 symmetrically arranged inside the support frame 1, with a pitch-changing mechanism between the extension seat 3 and the support frame 1, and a support rod 17 rotatably connected to the end of the extension seat 3; an ear hook 19 fixedly connected to the end of the support rod 17 away from the support frame 1, the ear hook 19 being arc-shaped for hanging the device on the ear; a control component between the extension seat 3 and the support rod 17 for controlling the movement direction of the extension seat 3; an infrared sensor 18 symmetrically fixedly connected to the side of the support frame 1 near the support rod 17, wherein an adjustment component is symmetrically arranged at the bottom of the support frame 1, and the adjustment component is electrically connected to the infrared sensor 18; and battery compartments 31 symmetrically fixedly connected to the support rod 17, with a strap 33 between the two battery compartments 31, and a tensioning mechanism on the side of the battery compartments 31 near the strap 33 for adjusting the size of the strap 33.

[0034] In this embodiment, the infrared sensor 18 can capture eye images by forming a Purchin spot (a bright reflective spot at the center of the pupil) on the cornea using infrared light. The coordinates of the pupil center are calculated by an ellipse fitting algorithm, and the relative displacement between the reflected light spot on the cornea and the pupil center is combined to achieve gaze tracking. This is a conventional method in the prior art, so it will not be described in detail.

[0035] Reference Figures 1-2 The variable pitch mechanism includes symmetrically arranged storage slots 2 at both ends of the support frame 1, an extension seat 3 slidably connected inside the storage slots 2, a micro motor 4 fixedly connected inside the support frame 1 near the storage slots 2, a screw 5 fixedly connected to the output end of the micro motor 4, a threaded hole 6 matching the screw 5 opened inside the extension seat 3, and a compression rod 7 fixedly connected between the storage slots 2 and the extension seat 3.

[0036] In this embodiment, the micro motor 4 is a conventional method in the prior art, capable of forward and reverse rotation. It should be explained that the compression rod 7 can adopt a telescopic rod-like structure with two compression chambers. That is, the compression rod 7 can compress at least one set of compression chambers by extending or retracting. The compression rod 7 is connected to the temporary storage chamber 8 through a one-way valve. In other words, gas only enters the temporary storage chamber 8 when the compression chamber is in a compressed state. When it is extended, it can adsorb outside air. When the micro motor 4 drives the screw 5 to rotate, it can move the extension seat 3 along the receiving groove 2, thereby realizing the adjustment of the distance between the two sets of support rods 17.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The control component includes a groove 20 formed on the side of the extension seat 3 near the support rod 17. An electromagnet 21 is fixedly connected inside the groove 20. A second spring 22 is fixedly connected to the electromagnet 21. A permanent magnet 23 is fixedly connected to the end of the second spring 22. A movable plate 24 is fixedly connected to the side of the permanent magnet 23 away from the second spring 22. A fixed plate 26 is fixedly connected to the side of the extension seat 3 near the support rod 17 and away from the groove 20. When the electromagnet 21 is energized, the electromagnet 21 and the permanent magnet 23 have the same magnetism on the side that is close to each other. The permanent magnet 23 and the fixed plate 26 are slidably connected to the groove 20.

[0038] In this embodiment, in the initial state, the two sets of support rods 17 are close to each other and attached to one side of the support frame 1 to reduce the space occupied by the device. When the device is used, the electromagnet 21 is energized, generating a repulsive force between it and the permanent magnet 23, thereby driving the permanent magnet 23 and the movable plate 24 to extend outward from the groove 20. At the same time, the two sets of support rods 17 will rotate relative to each other to facilitate wearing the device. When the device is not in use, the electromagnet 21 is de-energized. Under the action of the second spring 22, the permanent magnet 23 and the movable plate 24 are moved to the initial position to rotate the support rods 17 to the initial position.

[0039] Reference Figure 5 and Figure 7 It also includes a mounting groove 27 opened on the side of the movable plate 24 and the fixed plate 26 close to each other. Multiple sets of third springs 28 are fixedly connected inside the mounting groove 27. The ends of the third springs 28 are fixedly connected to pressure blocks 29 that are slidably connected to the mounting groove 27. Control switches 30 are fixedly connected on the side of the mounting groove 27 near the pressure blocks 29. Two sets of control switches 30 are electrically connected to the micro motor 4, and the two sets of control switches 30 are used to control the forward and reverse rotation of the micro motor 4, respectively. It also includes a limiting groove 25 opened on the side of the extension seat 3 near the groove 20. When the movable plate 24 moves into the groove 20, the pressure block 29 moves into the interior of the limiting groove 25.

[0040] In this embodiment, when the support rod 17 and the support frame 1 are in a vertical state (i.e., the device is in the open state), if there is a deviation between the size of the two sets of support rods 17 and the size of the user's head, the support rod 17 is rotated in the corresponding direction to press the pressure block 29 in the corresponding direction until the pressure block 29 contacts the control switch 30. At this time, the micro motor 4 will be triggered to rotate forward or reverse so as to drive the extension seat 3 to extend outward or retract inward along the support frame 1 until the size between the two sets of support rods 17 matches the size of the user's head. This not only increases the range of use of the device, but also improves the user's comfort.

[0041] Reference Figures 1-3 The adjustment component includes symmetrically arranged grooves 9 at the bottom of the support frame 1. A slide seat 11 is slidably connected inside the grooves 9. An adjustment rod 10 is fixedly connected inside the support frame 1 and fixedly connected to the slide seat 11. A first spring 12 is fixedly connected between the slide seat 11 and the grooves 9. The support frame 1 has a temporary storage cavity 8 connected to the compression rod 7. The temporary storage cavity 8 is connected to the adjustment rod 10 through a pressure relief valve, a solenoid valve and a pipe. The solenoid valve and the pressure relief valve are electrically connected to the infrared sensor 18. An imaging component is provided on the slide seat 11.

[0042] In this embodiment, after the device is worn, the infrared sensor 18 will locate the user's eyes and open the solenoid valve or the pressure relief valve accordingly. When the solenoid valve is opened, the compressed gas in the temporary storage chamber 8 enters the interior of the adjusting rod 10, thereby driving the slide 11 in the corresponding direction to move. When the pressure relief valve is opened, the gas in the adjusting rod 10 is released outward under the action of the first spring 12, thereby adjusting the position of the lens 14 to match the user's eyes and improve the user's viewing effect.

[0043] Reference Figures 1-4 The imaging component includes a lens frame 13 fixedly connected to the slide 11, a lens 14 fixedly connected to the lens frame 13, the lens 14 being used to superimpose virtual information onto the real field of vision, and an air inlet 15 opened between the slide 11 and the lens frame 13. A drain outlet 16 is opened at the bottom of the lens frame 13, and a hole communicating with the air inlet 15 is opened at the bottom of the storage slot 2. The hole is connected to the temporary storage chamber 8 through a solenoid valve and a pipe. The exhaust end of the pressure relief valve is connected to the hole at the bottom of the storage slot 2 through a pipe.

[0044] In this embodiment, a sensor can be installed on the support frame 1 or the lens frame 13 to monitor the water mist on the lens 14. This is a conventional method in the prior art, so it will not be described in detail. When the lens 14 fogs up, the corresponding solenoid valve will be opened, so that the gas in the temporary storage chamber 8 is blown toward the lens 14 through the air inlet 15, thereby reducing the water mist on the lens 14. It should be explained that when blowing air, no matter where the lens 14 is, the gas can stably enter the air inlet 15 through the hole on the storage groove 2.

[0045] Reference Figure 1 , Figure 2 and Figure 6 The tightening mechanism includes a guide groove 32 opened in the battery compartment 31, and a strap 33 slidably connected to the guide groove 32. The battery compartment 31 has an installation cavity 34 that communicates with the guide groove 32. A micro motor 4 is installed inside the installation cavity 34. A rotating shaft 35 is fixedly connected to the output end of the micro motor 4. A guide wheel 36 that fits against the strap 33 is fixedly connected to the rotating shaft 35. An installation roller 37 is fixedly connected to the rotating shaft 35. Multiple sets of rotating bars 38 are fixedly connected to the outer wall of the installation roller 37. A compressed air rod 39 that matches the rotating bars 38 is fixedly connected to the inner wall of the installation cavity 34. The micro motor 4 in the installation cavity 34 is electrically connected to the micro motor 4 in the support frame 1. The two sides of the end of the rotating bar 38 are inclined. The compressed air rod 39 is elastic and the end is arc-shaped. The compressed air rod 39 is connected to the temporary storage cavity 8 through a pipe.

[0046] In this embodiment, since users with larger faces have a relatively large distance between their ears along their head, the micro motor 4 inside the battery compartment 31 is activated when adjusting the distance between the support rods 17. The micro motor 4 rotates according to the adjustment direction of the support rods 17, thus adjusting the size of the strap 33 between the two battery compartments 31. It should be explained that when the micro motor 4 drives the guide wheel 36 to rotate, the friction between the strap 33 and the guide wheel 36 causes the strap 33 to move along the battery compartment 31. This ensures device stability while reducing pressure from the support rods 17 on the user's ears and head, and also reduces pressure from the support frame 1 on the user's nose bridge, further improving user comfort and extending the device's battery life. Additionally, it drives the rotating bar 38 to rotate, intermittently compressing the air compressor 39 and storing the gas in the temporary storage chamber 8.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
