Description

Technical Field

[0001] The present invention belongs to the technical field of smart glasses, and in particular relates to smart optical zoom glasses. Background Art

[0002] Compound refractive error is an abnormality in the eye's refractive system, which causes the light to not be accurately focused on the retina. It usually includes a combination of multiple refractive problems such as myopia, hyperopia and astigmatism. Among them, compound myopia refers specifically to the situation of suffering from myopia and astigmatism at the same time. At present, such visually impaired people are already common in our lives. In order to ensure a normal life, patients with both conditions need to prepare more than two pairs of glasses with different degrees at the same time, which is very inconvenient, especially in driving, sports, special operations or emergency situations. There are different levels of safety hazards, so a pair of glasses is needed to meet the needs of patients with both conditions and solve the carrying problem. Smart zoom glasses are born.

[0003] Currently, there are several smart glasses technologies, including but not limited to the following:

[0004] 1. Multifocal combination lenses set the focal length in different areas of the lens; the disadvantage is that there may be distortion or ghosting in the center of the field of view. In strong light environments, the contrast and clarity of the field of view may be affected, so there are safety hazards in work and life.

[0005] 2. The flexible variable focus lens driven by electrodeformation mainly utilizes the electro-dynamic properties of the material to convert electrical energy into mechanical energy, changing the shape of the liquid lens to achieve adjustable focal length. It has the characteristics of large structural zoom range, fast response speed and easy integration. However, when it is affected by external conditions such as temperature and gravity, its performance is greatly affected, and it is difficult to use in glasses with a wide field of view.

[0006] 3. Electro-variable liquid crystal lens is a device that uses electric field to control the arrangement of liquid crystal molecules, thereby changing the focal length of the lens. It has the characteristics of fast response speed, large zoom range, lightness and flexibility. However, only a few countries currently have this technology, and the material cost is expensive, so it cannot be popularized.

[0007] The above-mentioned technologies, especially electrodeformable lenses and electrozoom liquid crystals, as well as VR technology with microled projection, are difficult to achieve low cost, light weight, reliability and safety at the same time. Summary of the invention

[0008] In view of the problems raised by the above background technology, the purpose of the present invention is to provide intelligent optical zoom glasses.

[0009] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0011] The nose bridge is equipped with a distance sensor;

[0012] The pile head is equipped with a lens prism module;

[0013] The left temple comprises a left inner plate, the left inner plate is matched with a left outer shell, a PCB module, a left battery, a left speaker and a left brain-computer signal sensor are sequentially installed inside the left inner plate and the left outer shell from front to back, the left brain-computer signal sensor and the left speaker are signal-connected to the PCB module, a focus button, a lens switch, a microphone and a left power interface are installed on the left outer shell, the focus button, the lens switch and the microphone are signal-connected to the PCB module, and the left power interface is electrically connected to the left battery;

[0014] The right temple includes a right inner plate, and the right inner plate is matched with a right outer shell. The right inner plate and the right outer shell are installed with a signal sensor, a right battery, a right speaker and a right brain-computer signal sensor from front to back. The right outer shell is installed with a touch panel and a right power interface. The touch panel is connected to the signal sensor signal, the signal sensor is wirelessly connected to the PCB module, and the right power interface is electrically connected to the right battery.

[0015] It is further defined that the touch panel integrates the Bluetooth headset function, and such a design can achieve the purposes of making and receiving calls, listening and voice control.

[0016] It is further defined that the frame is equipped with lens buckles. Such a design can firmly fix lenses, such as myopia glasses, sunglasses clips, etc., to ensure that the lenses will not fall off or shake, providing a stable wearing experience.

[0017] It is further defined that the left battery is installed on the PCB module, and the right battery is installed in the touch panel. Such a design reduces the installation space, thereby reducing the volume and improving the wearing experience.

[0018] It is further specified that the left brain-computer signal sensor and the right brain-computer signal sensor have the same specifications and models. Such a design is conducive to spare parts replacement and rapid docking and interaction of signal functions.

[0019] It is further defined that the bottoms of the left shell and the right shell are both frosted, and such a design is anti-slip.

[0020] It is further defined that the nose bridge and the pile head are both provided with mounting grooves, and the mounting grooves are provided with avoidance openings. Such a design enables concealed installation of the distance sensor and the lens prism module, which is not obtrusive and improves the overall appearance.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention realizes rapid zooming of distant view, close view, macro distance and wide angle under the combined action of the lens prism module and the optical waveguide lens, wherein the optical imaging of the lens presents a clear optical image in the field of view of the lens in the form of "picture-in-picture" visual superposition through the total reflection prism and the optical waveguide lens, so that the wearer can see an extra high-definition image in the normal field of view of the glasses, and can realize intelligent zooming at any time through the distance sensor on the crossbar of the glasses, the left brain-computer signal sensor and the right brain-computer signal sensor, and can also perform manual focusing through the focusing button and voice focusing through the microphone.

[0023] In the present invention, under the effect of the electrochromic liquid crystal film, the purpose of adjusting the brightness relationship between the normal image of the lens and the image projected by the lens is achieved, making it easier to observe, and at the same time, the function of sunglasses can be achieved in an environment with strong light.

[0024] In the present invention, because it is a direct projection of the lens optical imaging, there is no distortion problem of pixels and colors. Visual superposition can ensure that the normal field of vision is not completely affected, and the high-definition picture after the lens imaging can flexibly adapt to the visual needs of far, near and macro.

A PCB module 603, a left battery 604, a left speaker 605 and a left brain-computer signal sensor 606 are installed in the left inner plate 601 and the left outer shell 602 from front to back. The left brain-computer signal sensor 606 and the left speaker 605 are connected to the PCB module 603 by signal. A focus button 607, a lens switch 608, a microphone 609 and a left power interface 610 are installed on the left outer shell 602. The focus button 607, the lens switch 608 and the microphone 609 are connected to the PCB module 603 by signal. The left power interface 610 is electrically connected to the left battery 604.

[0040] The right temple 7 includes a right inner plate 701, and the right inner plate 701 is matched with a right outer shell 702. The signal sensor 703, the right battery 704, the right speaker 705 and the right brain-computer signal sensor 706 are installed in the right inner plate 701 and the right outer shell 702 from front to back. The right outer shell 702 is installed with a touch panel 707 and a right power interface 708. The touch panel 707 is signal-connected to the signal sensor 703, the signal sensor 703 is wirelessly connected to the PCB module 603, and the right power interface 708 is electrically connected to the right battery 704.

[0041] Preferably, the touch panel 707 integrates the Bluetooth headset function. Such a design can achieve the purpose of making and receiving calls, listening and voice control. In fact, the function selection integrated in the touch panel 707 can also be considered according to the specific situation.

[0042] Preferably, the frame 2 is installed with a lens buckle 11. Such a design can firmly fix lenses, such as myopia glasses, sunglasses clips, etc., to ensure that the lenses will not fall off or shake, providing a stable wearing experience. In fact, the specifications, style, setting quantity and position of the lens buckle 11 can also be considered according to specific circumstances.

[0043] Preferably, the left battery 604 is installed on the PCB module 603, and the right battery 704 is installed in the touch panel 707. This design reduces the installation space, thereby reducing the volume and improving the wearing experience. In fact, the installation layout structure can also be considered according to specific circumstances.

[0044] Preferably, the left brain-computer signal sensor 606 and the right brain-computer signal sensor 706 have the same specifications and models. Such a design is conducive to the replacement of spare parts and the rapid docking and interaction of signal functions. In fact, the selection of specifications and models of the left brain-computer signal sensor 606 and the right brain-computer signal sensor 706 can also be considered according to specific circumstances.

[0045] Preferably, the bottoms of the left shell 602 and the right shell 702 are both frosted. Such a design is anti-slip. In fact, optimization treatment measures for the left shell 602 and the right shell 702 may also be considered according to specific circumstances.

[0046] Preferably, both the nose bridge 3 and the pile head 5 are provided with a mounting groove 12, and the mounting groove 12 is provided with an avoidance opening 13. Such a design realizes the hidden installation of the distance sensor 9 and the lens prism module 10, which is not abrupt and improves the overall appearance. In fact, the installation structure of the distance sensor 9 and the lens prism module 10 can also be considered according to specific circumstances.

[0047] In this implementation case, when using the smart optical zoom glasses, the lens prism module 10 is mainly composed of a micro-projector and a reflective prism. The micro-projector projects the image, and then reflects the image directly to the user's retina through the semi-transparent and semi-reflective structure of the reflective prism, superimposed with the real image, to form a visual experience of virtual-real fusion. The technology is mature and the cost is low, but the field of view angle is small, and the augmented reality experience is relatively weak, so optical waveguide lenses are used. The optical waveguide lenses use the principle of total reflection of light in the glass lens to ensure clear imaging and high image contrast, while providing a larger field of view. According to the different coupling structures of light entering and exiting the waveguide, they can be divided into diffraction optical waveguide technology and array optical waveguide geometric optical waveguide technology, which have the advantages of clarity, lightness, transparency, and a large field of view. The combination of the two presents a clear optical image in the field of view of the glasses in the form of "picture-in-picture" visual superposition, and the wearer can see an extra pair of high-definition images in the normal field of view of the glasses;

[0048] During this period, under the effect of the right brain-computer signal sensor 706 and the right power interface 708, the distance sensor 9 installed on the nose bridge 3 is controlled by AI technology to realize intelligent zoom. Manual focus can also be adjusted through the focus button 607 set on the left temple 6. Voice command focus can also be adjusted through the microphone 609 on the left temple 6. It is flexible and changeable to use. The zoom adjustment can ensure that the wearer's field of vision meets his or her own needs. In addition, the touch panel 707 set on the right temple 7 can set more detailed parameters.

[0049] Since the lens view is completely from natural light and is projected through the lens prism module 10, it is impossible to achieve light gain, so the outside of the glasses uses an electrochromic liquid crystal film 8 to adjust the brightness relationship between the normal lens image and the lens projection image, making it easier to observe, and can also achieve the function of sunglasses in a strong light environment, ensuring the use effect;

[0050] Since it is a direct projection of lens optical imaging, there is no pixel and color distortion problem. Visual superposition can ensure that the normal field of vision is not completely affected. The high-definition picture after lens imaging can flexibly adapt to visual needs such as long and short distances and macro distances. It is a safe, reliable, intelligent and efficient, easy to integrate and cost-effective visual aid device. It can also be expanded to a field of view of more than 180 degrees, ultra-long distance or ultra-micro distance, and observation of ultra-strong light scenes according to different environmental requirements.

[0051] Furthermore, the glasses also integrate a touchpad-controlled Bluetooth headset function, which can realize functions such as making and receiving calls, listening and voice control.
