Description

Technical Field

[0001] The utility model relates to the technical field of AR glasses, and more specifically, to an industrial intelligent AR glasses. Background Art

[0002] In industrial environments, augmented reality (AR) glasses have attracted widespread attention as a tool that can provide real-time information and guidance. Some industrial work environments require the wearing of a hard hat, such as power plant inspections, fire rescue operations, and surveying and mapping at construction sites. Other industrial work environments, such as electronics assembly workshops and home appliance repair, do not require the wearing of a hard hat.

[0003] The structure of traditional AR glasses does not take into account the compatibility with safety helmets. When a safety helmet needs to be worn, AR glasses often cannot be used well together. So people have developed AR glasses suitable for safety helmets, such as the augmented reality glasses disclosed in patent publication number CN217561848U, which include a headband and a buckle assembly. The headband is sleeved on the outer surface of the body of the safety helmet, and the buckle assembly is connected to the headband. The resettable pressure plate on the buckle assembly is used to hold the brim of the safety helmet to achieve the fixation of the headband and the safety helmet. Although this technical solution realizes the compatibility of AR glasses with safety helmets, it binds the AR glasses to the safety helmet and removes the AR glasses when the safety helmet is removed. Therefore, this product is not suitable for industrial use scenarios where a safety helmet is not required. Even if the headband of the AR glasses is directly put on the head, in some cases, the user has to take off the AR glasses first in order to put on the safety helmet, which not only increases the inconvenience of operation, but also leads to a decrease in work efficiency.

[0004] The above problems are worth solving. Utility Model Content

[0048] To better understand the purpose, technical solutions, and technical effects of the present invention, the present invention is further explained below with reference to the accompanying drawings and embodiments. It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. It should also be noted that the embodiments described below are intended only to illustrate the present invention and are not intended to limit the present invention.

[0049] It should be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may also be an intermediate element; when an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0050] The indicated orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the application is typically placed when in use, or the orientation or position relationship commonly understood by those skilled in the art, or the orientation or position relationship commonly placed when the product of the application is in use. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0051] The terms "first" and "second" are used only for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly specifying the number of technical features.

[0052] like Figures 1 to 3 As shown, an industrial smart AR glasses includes a headband 1 and a device host 2. The headband 1 and the device host 2 can be fixedly connected, rotatably connected, or detachably connected. The user wears the headband 1 to fix the device host 2 on the user's forehead.

[0053] In this embodiment, the back plate of the device host 2 is connected to the lower edge of the front portion 101 of the headband wearing part 1, which enables the headband wearing part 1 to avoid the heat dissipation holes on the back of the device, thereby preventing the heat dissipation effect of the device host 2 from being affected by the obstruction. The device host 2 is connected to the lower edge of the headband wearing part 1, and the upper surface of the device host 2 is located below the front portion 101 of the headband wearing part 1, so that the upper surface of the device host 2 forms a placement slot 20 in front of the headband wearing part 1. When the user wears a safety helmet, the brim of the safety helmet can be placed on the placement slot 20, the AR glasses are compatible with the use of the safety helmet, and the device host 2 can bear part of the weight of the safety helmet; when the user takes off the safety helmet, there is no need to take off the AR glasses. It can be seen that the use of AR glasses is independent of the safety helmet and can be firmly worn on the user's head.

[0054] The device main unit 2 is shaped like a crescent moon. Its width is equal to the distance between the two side legs 102 of the headband wearing piece 1. This makes the device main unit 2 closer to the visor of a hat, increasing the contact area with the visor and facilitating the stability of wearing AR glasses and a helmet simultaneously. The working motherboard inside the device main unit 2 is also shaped like a crescent moon to adapt to the internal structure of the device main unit 2, while providing ample space for the layout of electronic components, providing a physical foundation for the realization of multifunctional AR glasses.

[0055] The top of the front part 101 of the headband wearing component 1 is tilted backward, so that the front part 101 of the headband wearing component 1 can be smoothly inserted into the gap between the safety helmet and the wearer's head, and the back side of the front part 101 of the headband wearing component 1 can fit the forehead of the user (or wearer), thereby increasing the wearing contact area, reducing the gravity pressure of the device and the safety helmet, and improving wearing comfort.

[0056] The front portion 101 and the two side legs 102 of the headband 1 are integrally formed to form a ring with an opening. The two side legs 102 are elastic, making it convenient for the user to spread the two legs 102 and wear the headband. An elastic band 7 is provided at the opening of the headband 1. The two ends of the elastic band 7 are respectively connected to the two side legs 102. The elastic band 7 is used to adjust the tightness of the headband 1.

[0057] like Figure 5 As shown, in a preferred embodiment, a rotating shaft 11 is provided at the lower edge of the front portion 101 of the headband wearing part 1, an axis groove 22 is provided on the back of the device main body 2, an axis pin 221 is provided in the axis groove 22, and the rotating shaft 11 is rotatably connected to the axis pin, so that the device main body 2 can rotate relative to the headband wearing part 1 along the rotating shaft 11, and the rotation angle is 0 to 60°.

[0058] like Figure 4As shown, in an optional embodiment, the connection between the front portion 101 of the headband wearing part 1 and the support leg 102 has a concave arc structure 13. The concave arc structure 13 can reduce the weight of the front portion 101 of the headband wearing part 1, which is beneficial to reducing the overall front-end weight of the AR glasses product, and avoiding the front end of the product being too heavy and affecting the wearing stability and comfort. The back side of the headband wearing part 1 (the side in contact with the user's head) is provided with a flexible material such as silicone or sponge, which can prevent the hard material shell from causing damage to the user's head. Therefore, the flexible back side of the headband wearing part 1 can improve wearing comfort and safety.

[0059] In the present invention, an electrical socket 12 is provided at the end of one of the legs 102 of the headband 1. This socket 12 is electrically connected to the working motherboard of the device host 2. The first power supply host 8 plugs into the socket 12 via a power cord to provide power to the working motherboard. A flexible circuit board is provided within the headband 1. A wiring channel is provided at the connection between the headband 1 and the device host 2. One end of the flexible circuit board is connected to the socket 12, and the other end is electrically connected to the working motherboard via a connecting wire within the wiring channel.

[0060] The output interface of the first power supply host 8 is arranged on a side close to the electrical socket 12, which is convenient for connecting the output interface of the first power supply host 8 and the electrical socket 12 of the headband wearing component 1 on the same side, thereby shortening the length of the connecting wire.

[0061] In a specific embodiment, the front shell of the headband wearing part 1 is provided with a first threading hole 14, and the shell back plate 35 of the device host 2 is correspondingly provided with a second threading hole 24. The first threading hole 14 serves as one end of the wiring channel between the headband wearing part 1 and the device host 2, and the second threading hole 24 serves as the other end of the wiring channel, and the wiring channel has a built-in connection line for connecting the flexible circuit board and the working main board. In an AR glasses product in which the headband wearing part 1 and the device host 2 are a rotating connection structure, the first threading hole 14 is provided on the side of the front shell of the headband wearing part 1 close to the rotating shaft 11, and the second threading hole 24 is provided on the side wall of the shaft groove 22, and the first threading hole 14 and the second threading hole 24 are located on the same side of the rotating shaft 11.

[0062] The first power supply unit 8 has connection holes 81 at both ends. The elastic band 7 is detachably connected to the connection holes 81 to allow the first power supply unit 8 to be mounted on the elastic band 7. Specifically, one end of the elastic band 7 is connected to the end of the left leg 102, and the other end passes through the left and right connection holes 81 of the first power supply unit 8, and then connects to the end of the right leg 102. The bottom surface of the first power supply unit 8 (the side closest to the user's head) is a concave arc surface 82. This concave arc surface design helps it better fit the back of the user's head and improves wearing comfort.

[0063] In the present invention, a dual-diffraction optical machine component 3 is provided in the middle of the bottom of the device host 2. The dual-diffraction optical machine component 3 includes an image output optical machine 31 and a waveguide diffraction lens 32. The image output optical machine 31 is used to output the image source to the waveguide diffraction lens 32. The waveguide diffraction lens 32 is used to image the image source into the left and right eye fields of view of the wearer, thereby achieving the effect of left and right dual-channel augmented reality.

[0064] In one application example, the image source of the image output optical machine 31 comes from the cloud or a backend terminal. Specifically, in the firefighting industry, the command center monitors the on-site environment through a camera 41, analyzes the fire situation on the backend terminal, formulates a rescue plan, and then remotely transmits commands or analysis information and other data to the AR glasses of the firefighters on the scene. Finally, the image is imaged by the dual-diffraction optical machine assembly 3 and is transferred to the waveguide diffraction lens 32, enabling firefighters to obtain information simultaneously and communicate with the command center in real time.

[0065] In other application examples, the image source of the image output optical device 31 comes from the storage unit within the device host 2. The working mainboard of the device host 2 integrates at least a processing unit (MCU) and a storage unit. The processing unit can analyze the environment based on the real scene and spatial positioning data obtained by the camera 41 and / or sensors of the AR glasses, and automatically calculate how to accurately place the virtual content in the corresponding position in the real world, retrieve the display content from the storage unit, and display it at the corresponding position. For example, if the position of the cabinet in front is analyzed and the distance from the user is 2 meters, the text message "2 meters" and the distance ruler icon will be correctly displayed on the cabinet.

[0066] like Figure 7 and Figure 8As shown, in an optional embodiment, the dual-diffraction optical engine assembly 3 includes not only the image output optical engine 31 and the waveguide diffraction lens 32, but also includes: an optical engine main housing 33, a housing side cover 34, and a housing back plate 35. The optical engine main housing 33 has a cavity for installing the image output optical engine 31, and the cavity has a lateral opening. The housing side cover 34 can be detachably installed at the lateral opening of the optical engine main housing 33. The optical engine main housing 33 and the housing side cover 34 are assembled into a protective shell. A square heat dissipation hole 331 is provided on one side of the optical engine main housing 33, and a circular light exit hole 332 is provided on the other side of the opposite side. The square heat dissipation hole 331 and the circular light exit hole 332 are located on both sides of the lateral opening. The square heat dissipation hole 331 can provide a heat dissipation outlet for the image output optical engine 31 in the protective shell, which is beneficial for the discharge of heat generated by the image output optical engine 31 during operation. The size of the circular light outlet 332 is equal to the size of the light port of the image output optical machine 31, which can provide a larger light outlet for the image output optical machine 31 in the protective shell, and can meet the needs of the image output optical machine 31 to use a shorter focal length lens to achieve the same field of view, which is conducive to projecting the image onto the waveguide diffraction lens 32 at a close distance; not only that, the larger light outlet can pass more light, which helps to improve the overall brightness of the picture, thereby providing a clear virtual image.

[0067] The protective housing, formed by the main housing 33 of the optical engine and the housing side cover, has a mounting slot 333 for mounting the waveguide diffraction lens 32 on the side near the circular light exit 332. The housing back panel 35 has a corresponding retaining slot 351, which is adapted to the structure of the waveguide diffraction lens 32. The housing back panel 35 can be installed and removed from the protective housing, and the waveguide diffraction lens 32 is secured by the interlocking retaining slots 351 and mounting slots 333. Screw holes are provided at the upper and lower ends of the housing back panel 35. When maintaining or replacing the waveguide diffraction lens 32, the housing back panel 35 can be removed by screwing the screws, and then the waveguide diffraction lens 32 can be removed. When installing the waveguide diffraction lens 32, the combined structure of the retaining slots 351 and mounting slots 333 secures the waveguide diffraction lens 32, eliminating the need for complex lens adjustment and providing great convenience.

[0068] There are positioning pins 353 on the sides of the upper and lower screw holes of the shell back plate 35, and corresponding pin holes are provided on the back of the optical machine main shell 33. When installing the shell back plate 35, you only need to align the positioning pins 353 and insert them into the pin holes to quickly complete the installation.

[0069] The waveguide diffraction lens 32 has an arc-shaped notch 321 on its lower middle side. The width of the central lens only needs to cover the circular light exit aperture 332 to allow light to be smoothly coupled into the waveguide diffraction lens 32. The arc-shaped notch 321 not only serves as a positioning mechanism for installation, but also reduces lens material usage, saving costs. Correspondingly, a convex surface 352 is formed at the lower end of the retaining groove 351 on the housing backplate 35. This convex surface 352 mates with the lower surface of the arc-shaped notch 321 of the waveguide diffraction lens 32, ensuring a stable installation of the waveguide diffraction lens 32.

[0070] like Figure 5 and Figure 6 As shown, in an optional embodiment, the bottom center of the housing of the device main body 2 extends downward to form a housing cavity 21 for mounting the dual-diffraction optical-mechanical assembly 3. The inner cavity of the device main body 2 is connected to the housing cavity 21, facilitating the wiring strip of the dual-diffraction optical-mechanical assembly 3 to pass through the housing cavity 21 and then be electrically connected to the working mainboard. The housing cavity 21 is equipped with a removable chamber cover 211. Two studs are provided inside the housing 21, and corresponding bolt holes are provided in the chamber cover 211. The main housing 33 of the dual-diffraction optical-mechanical assembly 3 is provided with connecting ears with screw holes. The dual-diffraction optical-mechanical assembly 3 is placed in the housing cavity 21 and the chamber cover 211 is installed. The screw holes of the studs, the screw holes of the connecting ears, and the bolt holes of the chamber cover 211 are aligned. The bolts are passed from the outside to the inside. The bolts are tightened to secure the dual-diffraction optical-mechanical assembly 3 in the housing cavity 21. The side walls of the accommodating cavity 21 and the side walls of the cavity cover 211 are both provided with notches for avoiding the waveguide diffraction lens 32 .

[0071] In the present invention, a transparent protective mirror 5 is provided on the front bottom side of the device main body 2. The material of the protective mirror 5 can be polycarbonate. The polycarbonate protective mirror 5 has the characteristics of impact resistance and lightweight; the material of the protective mirror 5 can also be glass. The glass protective mirror 5 has a higher hardness, a harder and smoother surface, and is not easily scratched.

[0072] The bottom of the protective goggles 5 is provided with a support groove 52. When the user wears the AR glasses, the bridge of the nose is placed in the support groove 52, increasing the contact area between the nose bridge and the protective goggles 5, reducing the gravitational pressure of the protective goggles 5 on the nose bridge, and improving wearing comfort. Preferably, a flexible material such as silicone or sponge can be placed at the bottom of the support groove 52.

[0073] The protective glasses 5 are arc-shaped, the chord height of the protective glasses 5 is not less than 2 cm, and the width of the protective glasses 5 is greater than the width of the waveguide diffraction lens 32, so as to provide sufficient space for installing the double diffraction optical machine component 3 to avoid affecting the wearing; at the same time, the protective glasses 5 form a semi-enclosed protective structure on the front side of the double diffraction optical machine component 3.

[0074] like Figure 5As shown, an arc-shaped slot 23 is provided at the bottom of the shell of the device main body 2 corresponding to the position of the protective mirror 5, a snap-in block is provided on the inner wall of the shell adjacent to the arc-shaped slot 23, and a snap-in slot 51 is provided at the top of the protective mirror 5. The snap-in slots 51 correspond to the number and position of the snap-in blocks one by one. Through the above structure, the protective mirror 5 and the device main body 2 can be detachably installed, which is convenient for maintenance personnel to repair or replace the aged protective mirror 5.

[0075] like Figure 1 As shown, in the present invention, a camera 41 is provided in the middle of the front side of the device main body 2. The camera 41 is used to capture real-world images of the surrounding environment. The processing unit performs computational processing to achieve spatial positioning and three-dimensional mapping of the surrounding environment. Based on the real-world images captured by the camera 41, the AR glasses can overlay virtual information or graphics on them in real time. The captured data obtained by the camera 41 can be stored in the storage unit and can also be transmitted to other devices or uploaded to the cloud via a wireless network or mobile network.

[0076] Infrared LED fill lights 42 are provided on both sides of the camera 41. In a completely dark environment, the infrared light emitted by the infrared LED fill lights 42 illuminates the object, and the CCD or CMOS sensor in the camera 41 captures the reflected infrared light and converts it into an image, thereby enabling the camera 41 to have an infrared night vision function.

[0077] A time-of-flight (TOF) sensor 43 is located in the center of the front side of the device 2, below the camera 41. This sensor measures the distance between objects and the sensor in real time. It measures a distance value for each point in the field of view, generating a complete depth map. This depth map displays the depth information at each location, i.e., the actual distance corresponding to each pixel. This depth map is further processed, and the AR glasses system uses it to reconstruct the user's surrounding three-dimensional environment, allowing for the placement of virtual objects and other operations.

[0078] A thermal imaging lens assembly 6 is provided on the side of the device host 2. The thermal imaging lens assembly 6 generates images by detecting infrared radiation (heat) emitted by objects and can display the temperature distribution of different objects. Through the temperature information captured by the thermal imaging lens, the AR glasses system can overlay virtual information in the user's field of view, such as temperature readings, alarm prompts, etc.

[0079] In a specific application example, AR glasses with thermal imaging functions play a very important role in the field of firefighting. Thermal imaging lenses can quickly detect and display high-temperature areas, helping firefighters quickly locate the source of the fire. In some cases, the fire source may be blocked by walls, furniture, or other obstacles. Thermal imaging lenses can penetrate obstacles by detecting heat, helping firefighters to find hidden fire sources, facilitating firefighters to take measures earlier. Through thermal imaging images, firefighters can intuitively see the direction and speed of the fire spread, thereby better planning firefighting strategies and evacuation routes. In environments with thick smoke and low visibility, thermal imaging lenses use the obvious difference between the heat emitted by the human body and the surrounding environment to help firefighters find trapped people, making rescue work more efficient. After the fire is extinguished, thermal imaging lenses can be used to detect locations where embers or hot spots may exist to prevent re-ignition.

[0080] In the present utility model, the working mainboard of the device host 2 is integrated with a Beidou module and / or a GPS module and an inertial measurement module. The Beidou module and / or the GPS module obtains the user's current precise location information by receiving Beidou or GPS satellite signals; the inertial measurement module is used to detect the user's motion status, including walking direction, speed and posture.

[0081] The AR glasses system accesses a map database in the cloud or a storage unit, calculates the optimal path based on the user's current location and destination, and generates navigation instructions; the AR glasses system displays navigation instructions, such as navigation arrows and distance prompts, through the waveguide diffraction lens 32, and ultimately superimposes navigation information in the user's field of view.

[0082] like Figure 9 As shown, in the present invention, the AR glasses are equipped with a second power supply unit 9. The optional size of the second power supply unit 9 is 115×70×34mm, which is convenient for the operator to place the second power supply unit 9 in an arm pocket or chest pocket. The second power supply unit 9 is connected to the power socket 12 of the device unit 2 via a data cable 91 to achieve connection with the device unit 2.
