[0043] Example 1

[0044] like Figure 1 and Figure 2As shown, a long-life industrial smart AR glasses includes a headband wearing part 1 and a device host 2. The headband wearing part 1 and the device host 2 can be fixedly connected or rotatably connected. The user fixes the device host 2 on the user's forehead by wearing the headband wearing part 1. The front part 101 and the two side legs 102 of the headband wearing part 1 are integrally formed to form a ring with an opening, and the two side legs 102 have a certain elasticity, which is convenient for the user to spread the two legs 102 and wear them. An elastic band 7 is provided at the opening of the headband wearing part 1, and the two ends of the elastic band 7 are respectively connected to the two side legs 102, and the elastic band 7 is used to adjust the tightness of the headband wearing part 1.

[0045] In this embodiment, the device host 2 is internally provided with an electrically connected working mainboard and a built-in battery. The device host 2 is provided with a charging port, which is electrically connected to the built-in battery, enabling the user to charge the built-in battery through the charging port, thereby providing operating power for the device host 2. The elastic band 7 of the headband wearing part 1 is detachably provided with a mobile charging power supply 8. One of the legs 102 of the headband wearing part 1 is provided with an electrical socket 12 at the end, which is electrically connected to the working mainboard of the device host 2. The mobile charging power supply 8 is plugged into the electrical socket 12 using a power cord to provide power to the working mainboard. Among them, the headband wearing part 1 is internally provided with a flexible circuit board. The connection between the headband wearing part 1 and the device host 2 is provided with a wiring channel. One end of the flexible circuit board is connected to the electrical socket 12, and the other end is electrically connected to the working mainboard via a connecting wire within the wiring channel. It can be seen that the power required for the working mainboard of this embodiment can be obtained through two channels: one is to obtain power from the built-in battery, and the other is to obtain power by connecting the headband wearing part 1 to the mobile charging power supply 8 through the electrical socket 12.

[0046] like Figure 3 As shown, the output interface of the mobile charging power supply 8 is arranged on a side close to the electrical socket 12, which is convenient for connecting the output interface of the mobile charging power supply 8 and the electrical socket 12 of the headband wearing component 1 on the same side, thereby shortening the length of the power cable.

[0047] Among them, 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 is built-in with a connecting line for connecting the flexible circuit board and the working main board. In the 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.

[0048] This embodiment adopts a combination design of a built-in battery in the device host 2 and a detachable mobile charging power supply 8. When the built-in battery is insufficient, the mobile charging power supply 8 can continue to provide power, thereby increasing the battery life of the AR glasses product. The improvement in battery life is beneficial for users to wear the AR glasses product to perform long-term operations.

[0049] The mobile charging power bank 8 has connection holes 81 at both ends. The elastic band 7 can be detachably connected to these holes to allow the mobile charging power bank 8 to be mounted on the elastic band 7. Specifically, one end of the elastic band 7 connects to the end of the left leg 102, and the other end passes through the left and right connection holes 81 of the mobile charging power bank 8, respectively, before connecting to the end of the right leg 102. The bottom surface of the mobile charging power bank 8 (the side closest to the user's head) is a concave curved surface 82. This concave curved surface design helps it better fit the back of the user's head and improves wearing comfort.

[0050] like Figure 3 As shown, in an optional embodiment, the connection between the front portion 101 of the headband wearing component 1 and the support foot 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 component 1, which is beneficial to reducing the overall front end weight of the AR glasses product and avoiding the front end weight of the product being too heavy to affect the wearing stability and comfort.

[0051] like Figure 1 As shown, in a preferred 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.

[0052] 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.

[0053] 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.

[0054] In an optional embodiment, the back side of the headband wearing component 1 (the side that contacts 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 component 1 can improve wearing comfort and safety.

[0055] like Figure 4 As shown, in an optional 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°.

[0056] like Figures 5 to 7 As shown, 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 a left and right dual-channel augmented reality effect.

[0057] 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.

[0058] 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.

[0059] In a preferred embodiment, positioning pins 353 are provided on both 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, the positioning pins 353 only need to be aligned and inserted into the pin holes to quickly complete the installation.

[0060] In a preferred embodiment, a curved notch 321 is provided on the lower middle portion of the waveguide diffraction lens 32. 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 curved notch 321 not only serves as a positioning mechanism for installation, but also reduces lens material consumption, saving costs. Correspondingly, a convex curved surface 352 is provided at the lower end of the retaining groove 351 of the housing backplate 35. The convex curved surface 352 mates with the lower surface of the curved notch 321 of the waveguide diffraction lens 32, ensuring a stable installation of the waveguide diffraction lens 32.

[0061] like Figure 1 As shown, 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] To sum up, the AR glasses of the present invention have multiple functions and high power consumption. The battery of the AR glasses is divided into two parts: a built-in battery and a mobile charging power supply, which are placed at the front and back ends of the AR glasses respectively, thereby distributing part of the weight to the back of the AR glasses (that is, the side of the headband wearing part away from the device host), which can help disperse the weight, make it more stable when worn, and reduce the discomfort caused by excessive weight in the front.

[0066] In addition, the utility model increases the flexibility of product use. Users can choose whether to carry a mobile charging power supply according to their needs. When longer battery life is needed, the use time can be extended by connecting the mobile charging power supply, and the mobile charging power supply is directly fixed on the back side of the headband wearing piece, so there is no need to carry it separately, which is very convenient.

[0067] Example 2

[0068] like Figure 8 As shown, a long-lasting industrial smart AR glasses has the same structure as the first embodiment, including a headband wearing part 1 and a device host 2, with the difference that: a mobile charging power supply 8 is connected to the power socket via a data cable 83 and is suspended beside the headband wearing part 1. In this embodiment, a control host 9 is detachably mounted on the elastic band of the headband wearing part. The control host is provided with a microphone and stereo headphones. The main control board of the control host integrates a processor, a cellular network module (4G / 5G), an image codec module and an audio codec module. The processor is used to coordinate the work of each module to process video and audio data. The control host receives the audio and video data of the other party through the 4G / 5G network; the audio codec module decodes the received audio data stream and converts it into a playable audio signal, and the stereo headphones play the audio; the image codec module decodes the received video data stream and converts it into a displayable image frame, and the image output optical machine 31 outputs the image frame.

[0069] Camera 41 of device host 2 captures the video image in front of the user, which is then encoded by the processing unit and transmitted as a video data stream to the control host. The control host then collects the user's voice through a microphone and encodes it into an audio data stream. The control host then transmits the audio and video data to the other party via the 4G / 5G network. This demonstrates that the present invention, by configuring the control host, adds voice and video calling capabilities to AR glasses. Through a network connection, similar to live streaming, the image in front of the person is transmitted to the other party, enabling real-time communication.

[0070] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
