Description

Technical Field

[0001] The present application relates to the field of augmented reality, and in particular to smart glasses. Background Art

[0002] As a wearable device worn on the head, smart glasses have the property of transmitting the wearer's status to the outside. Although current smart glasses have built-in speakers, microphones, wireless connections, and even display functions, smart glasses on the market currently only focus on transmitting content to the wearer, lacking the interaction between the wearer and the smart glasses themselves, and ignoring the connection between the wearer and the people around him, resulting in a sense of distance between the wearer and the people around him. Summary of the invention

[0003] The main purpose of the present invention is to provide a smart glasses. The purpose is to add a light-emitting module to the frame, which is located between the wearer and the lens. Using the floodlight principle, the light source of the light-emitting module is not directly facing the lens, but facing upward and parallel to the lens, and the lens is made to generate floodlight through diffuse reflection. The size and color of the floodlight on the lens will change with the change of the brightness and color of the light source of the light-emitting module. Through the user displacement and acceleration data collected by the main control chip on the temple with the six-axis sensor, the user audio data collected by the microphone, and the value of the audio data received by the Bluetooth-connected mobile phone and other devices, the brightness and color of the light source of the light-emitting module change with the value of the collected data, so the floodlight on the lens also changes its size and color. Since the lens is transparent, the floodlight is only similar to adding a color coating on the lens, and will not block the field of vision, so the wearer and the people around him can see the changes in the size and color of the lens floodlight at the same time. The present invention brings a new virtual reality experience, enhances the interaction between the wearer and the smart glasses, reduces the sense of distance between the smart glasses and the wearer and the people around him, and helps virtual reality technology to better integrate into real life.

[0004] To achieve the above object, the present invention provides a pair of smart glasses comprising:

[0005] The frame is equipped with a lens slot, a lens, two receiving slots, and a bridge FPC (flexible circuit board) that runs through the frame. It is particularly noted that the receiving slot is located between the lens and the wearer, that is, between the lens slot and the wearer. In addition, the installation method of the lens is the same as that of conventional sheet metal glasses on the market. Since the frame and the lens have a certain degree of flexibility, the lens can be directly inserted into the lens slot card, and the lens is also a conventional material on the market.

[0006] There are two light-emitting modules, which are respectively placed in the two receiving grooves of the frame. The light-emitting module is composed of a light strip, a light guide strip and a transparent adhesive layer sandwiched between the two.

[0007] There are two temples with built-in PCBA (circuit board with integrated sensor), battery, speaker and USB C female socket.

[0008] The light-emitting module on the frame will change the color and brightness of the light source as the value of the data detected by the sensor on the temple changes, and the lens will appear floodlight through diffuse reflection, and the floodlight changes as the light source changes. Since the lens is transparent, the floodlight is just like adding a color coating to the lens and will not block the field of vision. Therefore, the wearer of the smart glasses and the people around them can see the changes in the color and size of the floodlight on the lens.

[0009] The light-emitting module is located between the wearer and the lens. The light source of the light-emitting module is not facing the lens but facing upward and parallel to the lens. The brightness and color of the light-emitting module will change with the change of the value of the data collected by the sensor on the PCBA, and the lens will be flooded through diffuse reflection. The floodlight changes with the change of the light source. Since the lens has a certain degree of transparency, the wearer and people around him can see the size and color changes of the lens floodlight.

[0010] Preferably, the light strip is composed of a plurality of LED lamp beads with colorful ICs and a strip FPC (flexible circuit board), and the LED lamp beads are attached to the strip FPC (flexible circuit board) using the COB (chip on board) process.

[0011] Preferably, the light-emitting module is composed of a light strip and a light guide strip, the light guide strip has flexible physical properties, and the material is a uniform mixture of modified PMMA (polymethyl methacrylate) and a light diffuser ((polysilsesquioxane)) with a ratio greater than or equal to 0.5 and less than or equal to 5%.

[0012] Preferably, the light emitting module is arranged in the receiving groove, and its length and width are consistent with the receiving groove, and its thickness is less than or equal to the receiving groove. Therefore, after the light emitting module is embedded in the receiving groove, its upper surface is lower than or flush with the inner wall of the lens ring of the lens frame.

[0013] Preferably, the PCBA (i.e., circuit board with integrated sensors) in the temple includes but is not limited to a main control chip, a six-axis sensor (i.e., a three-axis acceleration sensor and a three-axis angular velocity sensor integrated), user displacement and acceleration data collected by the main control chip in cooperation with the six-axis sensor, user audio data collected by a microphone, and audio data received by devices such as Bluetooth-connected mobile phones.

[0014] Preferably, the frame has a built-in bridge FPC (flexible circuit board), which simultaneously connects the light-emitting module in the frame, as well as the right temple and the left temple.

[0015] Beneficial effects:

[0016] The present invention provides a kind of smart glasses, which aims to add a light-emitting module to the frame, which is located between the wearer and the lens. By using the principle of floodlighting, the light source of the light-emitting module is not facing the lens, but facing upward and keeping parallel with the lens. The size and color of the floodlight will change with the change of the brightness and color of the light source of the light-emitting module. Through the user displacement and acceleration data collected by the main control chip in conjunction with the six-axis sensor, the user audio data collected by the microphone, and the audio data received by the Bluetooth-connected mobile phone and other devices, the brightness and color of the light source of the light-emitting module will change with the change of the value of the collected data. Since the lens is transparent, the floodlight is just like adding a color coating on the lens, and will not block the field of vision, so the wearer and the people around him can see the change of the color and size of the lens floodlight. The present invention brings a new virtual reality experience, enhances the interaction between the wearer and the smart glasses, reduces the sense of distance between the wearer and the people around him, and helps the virtual reality technology to be better integrated into real life.

[0017] For example, many times the wearer uses smart glasses to talk or call a voice assistant. Traditional glasses can only send and receive audio at the temples. During this process, the wearer seems to be talking to himself or herself, which can easily lead to embarrassing situations. The smart glasses provided by this patent collect the numerical changes of the audio so that the lens's glare changes in color and size as the numerical changes, so that people around can know that the wearer is interacting with the glasses, avoiding unnecessary embarrassment. For example, when users usually run, it is rather monotonous to just listen to music. With the smart glasses provided by this patent, the built-in six-axis sensor of the smart glasses detects the user's moving speed, and the glare on the lens spreads from the center to both sides like running water. The faster the wearer moves, the faster the glare spreads, and it feels like surfing. Since the lens is transparent, the glare is just like adding a colored coating to the lens, and does not block the field of vision. Therefore, it increases the fun and virtual immersion of running without affecting the functionality of the glasses. BRIEF DESCRIPTION OF THE DRAWINGS

The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0044] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or abutment, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly defined. In addition, FPC in the present invention uniformly refers to a flexible printed circuit board, and FPC hereinafter refers to a flexible printed circuit board. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The following is a description of a smart glasses provided by the present invention in conjunction with the accompanying drawings. The present invention provides a smart glasses 100, in which a light-emitting module 500 is added to a frame 200. By using the principle of floodlighting, the light source of the light-emitting module 500 is not facing the lens 220 of the smart glasses 100, but facing upward and parallel to the lens 220, and the lens 220 generates floodlighting through diffuse reflection. The size and color of the floodlighting will change with the change of the brightness and color of the light source of the light-emitting module 500. Through the user displacement and acceleration data collected by the main control chip in conjunction with the six-axis sensor, the user audio data collected by the microphone, and the audio data received by the Bluetooth-connected mobile phone and other devices, the brightness and color of the light source of the light-emitting module 500 will change with the change of the value of the collected data. Since the lens 220 is transparent, the floodlighting is just like adding a color coating to the lens 200, and will not block the field of view, so the wearer and the people around him can see the size and color changes of the floodlight of the lens 220. The present invention brings a new virtual reality experience, enhances the interaction between the wearer and the smart glasses, reduces the sense of distance between the wearer and the people around them caused by the smart glasses, and helps virtual reality technology to be better integrated into real life.

[0047] For example, refer to Figure 1 , Figure 4 , Figure 7The module of the smart glasses 100 includes a frame 200, a lens groove 210, a lens 220, a receiving groove 230, a bridge FPC 240, a light emitting module 500, a right temple 300, and a left temple 400.

[0048] The functional layout of the present invention is described as follows: Figure 2 As shown, the frame 200 is provided with two light-emitting modules 500, one for each of the left and right mirror grooves. The 26 built-in lamp beads 531 of the light-emitting module 500 support RGB full-color adjustment and brightness adjustment, and are used to provide light sources for the floodlight effect of the lens 220; the right temple 300 includes a main control chip, Bluetooth (for audio transmission and pairing), a six-axis sensor (with a three-axis acceleration and a three-axis gyroscope, used to collect moving speed and moving direction data), a microphone (collecting the wearer's audio data), a USB C interface (for charging and data transmission), and a speaker (playing audio, which can form a stereo with the speaker of the left temple 400); the left temple 400 includes a battery (for storing and releasing electrical energy) and a speaker (playing audio, which can form a stereo with the speaker of the right temple 300). The frame 200, the left temple 400, and the right temple 300 are connected together through FPC240 to share electrical energy and perform data interaction between modules.

[0049] It should be pointed out that when the smart glasses 100 are AR glasses, the smart glasses 100 have the modules necessary for AR glasses, and when the smart glasses 100 are Bluetooth audio glasses, the smart glasses 100 have the modules necessary for Bluetooth audio glasses.

[0050] It should be noted that the installation method of the lens 220 is the same as that of conventional sheet metal glasses on the market. Since both the frame and the lens have a certain degree of flexibility, the lens can be directly inserted into the lens slot, and the lens 220 is also made of conventional materials on the market.

[0051] Optionally, in one embodiment, the receiving groove 230 of the light emitting module 500 is adjacent to the lens groove 210 and parallel to the lens 220 in the lens ring, and is located on the inner side of the lens 220 (ie, the side close to the wearer). Figure 6 In the figure, the lens 220 and the light-emitting module 500 are both cross-sectional views from a side angle. The light-emitting module 500 is located between the wearer and the lens 220 and is adjacent to the lens 220. Since the surface of the lens 220 is smooth and delicate, if the light source of the light-emitting module 500 is facing the lens 220, it is easy to generate mirror reflection and cause damage to the eyes. Therefore, by utilizing the principle of floodlighting, the light source of the light-emitting module 500 is directed upward and parallel to the lens 220. The diffused reflected light emitted by the light-emitting module 500 can expand to the lens 220 to generate floodlight. As the brightness and color of the light source of the light-emitting module 500 change, the size and color of the floodlight will also change accordingly.

[0052] It should be noted that if Figure 6 As shown, the frame 200 is not parallel to the horizontal plane. The angle between α and the vertical line in the figure is 10°. According to the theory of ergonomics, the 10° forward tilt angle is more conducive to the visual activities of the middle and near fields, and can prevent the light of the light-emitting module 500 from directly hitting the eyes and causing damage to the eyes.

[0053] Optionally, in one embodiment, if Figure 4 As shown, the light-emitting module 500 is composed of a light guide strip 510, a transparent adhesive layer 520, and a light strip 530 from top to bottom. The assembly method is as follows: firstly, the light strip 530 is attached to the bottom of the receiving groove 230 by adhesive, and then the transparent adhesive layer 520 is filled on the light strip 530. The transparent adhesive layer 520 can be a transparent UV adhesive with strong viscosity and the thickness of the transparent adhesive layer 520 is greater than the height of the lamp beads 531 on the light strip 530. Finally, the light guide strip 510 is covered on the transparent adhesive layer 520 so that the light strip 530, the transparent adhesive layer 520, and the light strip 530 are bonded into a whole.

[0054] Optionally, in one embodiment, Figure 6 From the side view cross-sectional view of the light-emitting module 500 and the lens 220, it can be seen that the lamp bead 531 is the direct source of light. In order to avoid excessive diffuse reflection causing eye discomfort, the lamp bead 531 is placed at the bottom of the receiving groove 230. It can be understood that the light strip 530 on which the lamp bead 531 is placed is also placed at the bottom of the receiving groove 230 to narrow the light beam angle. In addition, if the light guide bar 510 exceeds the receiving groove 230, it is also easy to cause excessive diffuse reflection. Therefore, the light-emitting module 500 is arranged in the receiving groove 230, and its length and width are consistent with the receiving groove 230. After being placed in the receiving groove 230, the height of the light guide bar 510 is lower than or equal to the upper edge of the receiving groove 230, that is, after the light-emitting module 500 is embedded in the receiving groove 230, its upper surface is lower than or flush with the inner wall of the lens ring. In addition, if Figure 3 The receiving groove 230 is provided with a through hole 250 on the inner side of the frame 200, so as to facilitate the connection FPC 532 of the light strip 530 to be led out and connected to the Figure 2 The bridge FPC 240 runs through the frame 200 and the right temple 300 and the left temple 400.

[0055] Optionally, in one embodiment, if Figure 4 As shown, the light strip 530 of the light module 500 is composed of multiple LED lamp beads 531 with colorful ICs and a strip FPC. The COB (chip on board) process is used to attach the lamp beads 531 to the strip FPC. In order to meet the requirements of better uniformity of the light emitted by the light module 500 and control costs (control the number of lamp beads 531), as shown in FIG. Figure 5As shown in the figure, it is necessary to control the distance X between the lamp beads 531 within the range of beam intersection. Given the distance Y between the lamp beads 531 and the upper surface of the light guide bar 510 and the light-emitting angle of the lamp beads 531, that is, the beam angle, the calculation formula for the distance X between the lamp beads 531 is: 0 < X ≤ 2Y / tanβ, where β = (180° - beam angle) / 2.

[0056] Optionally, in an embodiment, since the light-emitting module 500 is placed on the frame 200 of the smart glasses 100, extrusion is likely to occur during actual use. To ensure the quality and safety of the smart glasses 100, the main material of the light guide bar 510 is modified PMMA (polymethyl methacrylate) with a proportion of 95%. To ensure a better balance between the light homogenization effect and light transmittance, a light diffusing agent (polyhedral oligomeric silsesquioxane) with a proportion of 5% is uniformly mixed into the main material. In addition, the front and back sides of the light strip 530 on the light guide bar 510 are subjected to frosted texturing treatment to make the light emitted by the light strip 530 softer.

[0057] Optionally, in an embodiment, as Figure 2 shown, the right temple 300 includes a main control chip for data signal conversion and task processing, and receives and sends audio data to devices such as mobile phones through Bluetooth. It receives the user displacement and acceleration data of the wearer through a six-axis sensor (i.e., an integrated triaxial acceleration and triaxial angular velocity sensor), receives the audio data of the wearer through a microphone, and then converts the numerical changes of the above received data into the color and brightness changes of the light source of the light-emitting module 500 in real time, driving the change of the light on the lens 220; in addition, it charges the battery of the left temple 400 through a USB C female socket; the left temple 400 contains a lithium battery for supplying power to the light-emitting module 500 of the frame 200 and the right temple 300 and balancing the weight of the smart glasses 100. In addition, the built-in speakers in the left temple 400 and the right temple 300 can form a stereo sound effect.

[0058] Optionally, in an embodiment, as Figure 7 shown, the bridging FPC 240 is placed in the frame 200 by double-shot injection molding, and it is simultaneously connected to the connecting FPC 532 of the light-emitting module 500, the right temple 300, and the left temple 400. The bridging FPC 240 is equivalent to the data and electrical energy transmission medium for the frame 200, the right temple 300, and the left temple 400.

[0059] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
