Description

Technical Field

[0001] The utility model relates to the AR technical field, in particular to an AR glasses. Background Art

[0002] At present, the application of AR technology is becoming more and more extensive, and AR glasses are generally welcomed by users.

[0003] AR glasses are the product most likely to replace mobile phones in the future. Due to weight and volume limitations, there is little space left for circuit boards and batteries (low battery life). In addition, color light engines, various detection cameras (up to 5 or more), and various detection sensors are distributed on the front frame of the glasses. This means that there are hundreds of connection signals between the front frame and the main processor of the left temple. Some signals, such as left and right speaker signals, need to cross the front frame from the left temple to the right temple. This makes the speaker signal loop very long, and EMI is very likely to cause problems.

[0004] In addition, ordinary AR glasses are very easy to fall off during exercise, and there is a risk of breaking the glasses.

[0005] Finally, due to the smaller space on the right temple of AR glasses, the battery capacity is smaller, so the standby time of AR glasses is not long, which has a great impact on the actual application of users. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0050] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] The AR glasses of this embodiment include a first temple 10, a second temple 20, a frame 30, a retractable cable 40, etc. Figures 1 to 4 shown.

[0052] The first temple 10 has one end rotatably connected to the frame 30 and the other end thereof has a first connecting member and a first conductive member.

[0053] The second temple 20 has one end rotatably connected to the frame 10 and the other end thereof has a second connecting member and a second conductive member.

[0054] The retractable cable 40 has a third connector and a third conductive member 41 at one end and a fourth connector and a fourth conductive member 42 at the other end. The cable 40 has an energy storage module, and the output ends of the energy storage module are electrically connected to the third conductive member 41 and the fourth conductive member 42 respectively. The energy storage module can be charged separately by an external power supply for repeated use. The energy storage module of this embodiment is a battery pack.

[0055] The third connector is detachably connected to the first connector. When the third connector is connected to the first connector, the third conductive member 41 contacts the first conductive member, and the third conductive member 41 and the first conductive member can transmit electrical signals. The electrical energy stored in the energy storage module is transmitted to the first conductive member via the third conductive member 41, so that the energy storage module supplies power to the electrical components in the first temple. When the third connector is separated from the first connector, the third conductive member 41 is separated from the first conductive member, disconnected, and the third conductive member 41 and the first conductive member are disconnected from the electrical signal transmission.

[0056] The fourth connector is detachably connected to the second connector. When the fourth connector is connected to the second connector, the fourth conductive member 42 contacts the second conductive member, and the fourth conductive member 42 and the second conductive member can transmit electrical signals. The electrical energy stored in the energy storage module is transmitted to the second conductive member via the fourth conductive member 42, so that the energy storage module supplies power to the electrical components in the second temple. When the fourth connector is separated from the second connector, the fourth conductive member 42 is separated from the second conductive member, disconnected, and the fourth conductive member 42 and the second conductive member are disconnected from the electrical signal transmission.

[0057] Therefore, when the third connecting member is connected to the first connecting member, electrical signals are transmitted between the cable 40 and the first temple 10 via the third conductive member 41 and the first conductive member, so that the cable 40 supplies power to the first temple 10 .

[0058] When the fourth connecting member is connected to the second connecting member, electrical signals are transmitted between the cable 40 and the second temple 20 via the fourth conductive member 42 and the second conductive member, so that the cable 40 supplies power to the second temple 20 .

[0059] The cable 40 has a certain degree of elasticity. After the user puts on the AR glasses, the cable 40 fits against the back of the user's head and can be retracted and fixed according to the different head shapes of the users. It plays the role of firmly holding the glasses during exercise and preventing them from falling off.

[0060] The AR glasses of this embodiment are designed with a first connector and a first conductive member on the first temple 10, a second connector and a second conductive member on the second temple 20, a third connector and a third conductive member 41 at one end of a cable 40, and a fourth connector and a fourth conductive member 42 at the other end of the cable 40. The cable 40 has an energy storage module, and the output end of the energy storage module is electrically connected to the third conductive member 41 and the fourth conductive member 42 respectively; when the third connector is connected to the first connector, the third conductive member 41 contacts the first conductive member, so that the energy storage module supplies power to the electrical devices in the first temple 10. ; When the fourth connecting member is connected to the second connecting member, the fourth conductive member 42 contacts the second conductive member, so that the energy storage module supplies power to the electrical components in the second temple 20; moreover, the cable 40 is scalable and can be adapted to different head shapes, thereby preventing the AR glasses from falling off when the user is exercising; therefore, the AR glasses of this embodiment, through the connection of the cable 40 with the first frame 10 and the second frame 20, can reinforce the glasses to prevent them from falling off during exercise, and can also supply power to the first frame 10 and the second frame 10, thereby solving the technical problems in the prior art that the AR glasses have a short battery life and are easy to fall off during exercise.

[0061] In this embodiment, the first temple is the left temple, and the second temple is the right temple. Alternatively, the first temple is the right temple, and the second temple is the left temple.

[0062] In some embodiments of the present application, in order to ensure the connection stability between the first connecting member and the third connecting member and facilitate assembly and disassembly, the first connecting member includes a first magnetic part, the third connecting member includes a third magnetic part, and the first magnetic part and the third magnetic part have opposite magnetic properties. When the third magnetic part and the first magnetic part are attracted together, the third conductive member 41 contacts the first conductive member.

[0063] In some embodiments of the present application, in order to ensure the connection stability between the second connector and the fourth connector and facilitate assembly and disassembly, the second connector includes a second magnetic part, the fourth connector includes a fourth magnetic part, and the second magnetic part and the fourth magnetic part have opposite magnetic properties. When the fourth magnetic part and the second magnetic part are attracted together, the fourth conductive part 42 contacts the second conductive part.

[0064] In some embodiments of the present application, the first connecting member has a first contact surface, and the first conductive member is recessed / convexly arranged on the first contact surface; the second connecting member has a second contact surface, and the second conductive member is recessed / convexly arranged on the second contact surface; the third connecting member has a third contact surface, and the third conductive member is recessed / convexly arranged on the third contact surface; the fourth connecting member has a fourth contact surface, and the fourth conductive member is recessed / convexly arranged on the fourth contact surface.

[0065] When the first contact surface contacts the third contact surface, the first magnetic portion and the third magnetic portion are attracted together, and the first conductive member contacts the third conductive member, and the two can transmit electrical signals.

[0066] When the first contact surface is separated from the third contact surface, the first magnetic portion is separated from the third magnetic portion, and the first conductive member is disconnected from the third conductive member.

[0067] When the second contact surface contacts the fourth contact surface, the second magnetic portion and the fourth magnetic portion are attracted together, and the second conductive member contacts the fourth conductive member, and the two can transmit electrical signals.

[0068] When the second contact surface is separated from the fourth contact surface, the second magnetic portion is separated from the fourth magnetic portion, and the second conductive member is disconnected from the fourth conductive member.

[0069] The contact surface plays a role of limiting, and the conductive member is arranged concavely or convexly on the contact surface. When the two contact surfaces are in contact, the conductive members on the two contact surfaces are in contact and connected, thereby avoiding damage to the conductive member and ensuring the connection reliability between the two conductive members.

[0070] For example,

[0071] The first conductive member is disposed concavely on the first contact surface, and correspondingly, the third conductive member is disposed convexly on the third contact surface.

[0072] The second conductive member is disposed concavely on the second contact surface, and correspondingly, the fourth conductive member is disposed convexly on the fourth contact surface.

[0073] In some embodiments of the present application, in order to ensure the connection stability between the first connecting member and the third connecting member, and in order to ensure the connection stability between the second connecting member and the fourth connecting member, the first magnetic portion is annular, buried in the first contact surface, and surrounded by the outside of the first conductive member; the second magnetic portion is annular, buried in the second contact surface, and surrounded by the outside of the second conductive member; the third magnetic portion is annular, buried in the third contact surface, and surrounded by the outside of the third conductive member; the fourth magnetic portion is annular, buried in the fourth contact surface, and surrounded by the outside of the fourth conductive member.

[0074] In some embodiments of the present application, in order to further ensure the connection stability between the first connector and the third connector, the first connector further includes a first clamping portion, the third connector further includes a third clamping portion, and the first clamping portion and the third clamping portion are detachably clamped. When the first contact surface contacts the third contact surface, the first magnetic portion and the third magnetic portion are attracted together, the first conductive member contacts the third conductive member, and the first clamping portion and the third clamping portion are clamped.

[0075] In some embodiments of the present application, in order to further ensure the connection stability between the second connector and the fourth connector, the second connector further includes a second clamping portion, the fourth connector further includes a fourth clamping portion, and the second clamping portion and the fourth clamping portion are detachably clamped. When the second contact surface contacts the fourth contact surface, the second magnetic portion and the fourth magnetic portion are attracted together, the second conductive member contacts the fourth conductive member, and the second clamping portion and the fourth clamping portion are clamped.

[0076] For example, the first clamping portion is a clamping slot, and the third clamping portion is a buckle if matched; the second clamping portion is a clamping slot, and the fourth clamping portion is a buckle if matched.

[0077] In some embodiments of the present application, the first conductive member includes a first power supply terminal, which is a pin seat of a spring pin connector; the third conductive member includes a third power supply terminal, which is a probe of a spring pin connector, and the top of the probe has a certain elasticity. When the third connecting member is connected to the first connecting member, the third power supply terminal is in elastic contact with the first power supply terminal.

[0078] The second conductive member includes a second power supply terminal, which is a pin seat of a spring pin connector; the fourth conductive member includes a fourth power supply terminal, which is a probe of a spring pin connector, and the top of the probe has a certain elasticity. When the fourth connecting member is connected to the second connecting member, the fourth power supply terminal is in elastic contact with the second power supply terminal.

[0079] The output end of the energy storage module is electrically connected to the third power supply terminal and the fourth power supply terminal respectively. The electric energy output by the energy storage module is transmitted to the first temple 10 through the third power supply terminal and to the second temple 20 through the fourth power supply terminal.

[0080] A spring pin connector (POGO PIN) includes a matching pin seat (female seat) and a probe (male head). The center of the female seat is concave, and the center of the male head is protruding and retractable. By using a spring pin connector, it is conducive to good contact and a certain contact extension, preventing the spring pin connector from generating excessive stress and causing damage to the product when the glasses fall.

[0081] By using a spring pin connector in the AR glasses, the stability and reliability of signal transmission between the cable 40 and the first glasses 10 and the second glasses 20 are ensured.

[0082] In some embodiments of the present application, in order to facilitate communication between the first frame and the second frame,

[0083] The first conductive member also includes a first communication terminal, which is a pin seat of a spring pin connector; the third conductive member also includes a third communication terminal, which is a probe of a spring pin connector; when the third connecting member is connected to the first connecting member, the third communication terminal is in elastic contact with the first communication terminal.

[0084] The second conductive member also includes a second communication terminal, which is a pin seat of a spring pin connector; the fourth conductive member also includes a fourth communication terminal, which is a probe of a spring pin connector; when the fourth connecting member is connected to the second connecting member, the fourth communication terminal is in elastic contact with the second communication terminal.

[0085] The cable has a communication line therein, one end of the communication line is electrically connected to the third communication terminal, and the other end of the communication line is electrically connected to the fourth communication terminal.

[0086] Therefore, when the third connecting member is connected to the first connecting member and the fourth connecting member is connected to the second connecting member, the third communication terminal is elastically in contact with the first communication terminal, the fourth communication terminal is elastically in contact with the second communication terminal, and the first frame communicates with the second frame through the communication line in the cable.

[0087] The spring pin connector needs to be customized according to different glasses shapes and the amount of transmitted signals to achieve the connection between the two temples and the cable 40. The spring pin connector is gold-plated and impedance-controlled, so that there is no signal loss problem when the temples are connected to the cable 40.

[0088] In some embodiments of the present application, a signal enhancement driving module is provided on the communication line. For example, a signal enhancement driving module is provided at one end of the communication line, and a signal enhancement driving module is also provided at the other end of the communication line. The signal driving module can drive and enhance the signal to pass through the cable to prevent the signal quality from being attenuated due to a too long signal transmission path.

[0089] In some embodiments of the present application, a signal enhancement driving module 43 is provided in the connection line (charging line) between the output end of the energy storage module and the third power supply terminal; a signal enhancement driving module 44 is provided in the connection line (charging line) between the output end of the energy storage module and the fourth power supply terminal.

[0090] In this embodiment, the battery pack, the signal enhancement driving module, the third conductive member 41, and the fourth conductive member 42 are embedded into the flat cable through silica gel. The outer skin of the cable is retractable. The communication line is attached to the surface of the battery pack and is independent of the charging line.

[0091] In some embodiments of the present application, a charging chip (Charger IC), a battery, and a low-power first Bluetooth communication module are provided in the first temple 10; the charging chip is electrically connected to the first power supply terminal and the first communication terminal, respectively; the charging chip charges the battery, and the charging chip controls the operation of the first Bluetooth communication module.

[0092] The second temple 20 is provided with a main processor, a voltage conversion module (Power IC), and a low-power second Bluetooth communication module; one end of the voltage conversion module is electrically connected to the second power supply terminal, and the other end of the voltage conversion module is electrically connected to the main processor; the main processor is electrically connected to the second communication terminal, and the main processor controls the operation of the second Bluetooth communication module.

[0093] The first Bluetooth communication module performs wireless communication with the second Bluetooth communication module.

[0094] When the first temple and the second temple are not connected to the cable 40, the charging chip and the main processor communicate wirelessly through the first Bluetooth communication module and the second Bluetooth communication module to prevent the signal from crossing the frame from the first temple to the second temple, to prevent the signal loop from being too long, and to prevent EMI problems. The battery supplies power to the first temple, the frame, and the second temple.

[0095] When the first temple and the second temple are connected to the cable 40, the first power supply terminal is electrically connected to the third power supply terminal, and the second power supply terminal is electrically connected to the fourth power supply terminal. The power output by the energy storage module in the cable 40 is transmitted to the first power supply terminal through the third power supply terminal, and then transmitted to the charging chip through the first power supply terminal, and the charging chip charges the battery. At the same time, the power output by the energy storage module in the cable 40 is transmitted to the second power supply terminal through the fourth power supply terminal, and then transmitted to the voltage conversion module through the second power supply terminal, and the voltage conversion module supplies power to the main processor.

[0096] When the first temple and the second temple are connected to the cable 40, the first communication terminal is electrically connected to the third communication terminal, the second communication terminal is electrically connected to the fourth communication terminal, and the charging chip communicates with the main processor through the first communication terminal, the third communication terminal, the communication line, the fourth communication terminal, and the second communication terminal.

[0097] Therefore, when the AR glasses are worn for exercise, the first temple and the second temple are respectively connected to the cable 40 for charging and signal transmission. At this time, the cable 40 (with elasticity) will bypass the back of the user's head to play a fixing role, so that it is not easy to fall and damage the glasses during exercise, and play a protective role. After the cable 40 is connected to the two temples, the energy storage module (battery pack) in the cable 40 immediately charges the battery in the first temple through the charger IC, so that all the power consumed during exercise comes from the external battery pack. In addition, when the charger IC detects that the cable 40 starts to connect and charge, it will transmit a signal to the main processor of the second temple through the first Bluetooth communication module and the second Bluetooth communication module. The main processor determines that the cable 40 has been connected, and then turns off the wireless work of the first Bluetooth communication module and the second Bluetooth communication module. The signal between the first temple and the second temple is directly transmitted through the cable 40 for physical medium, which greatly reduces the long-term whole machine working power consumption of the AR glasses (reducing the wireless communication power consumption), thereby achieving the practical goal of making the AR glasses last longer during exercise. When the exercise is completed, the cable 40 can be removed, and at this time, the first Bluetooth communication module and the second Bluetooth communication module resume normal operation.

[0098] In some embodiments of the present application, in order to facilitate the acquisition of the battery power, a power meter is also provided in the first temple 10, which detects the battery power and sends the detected signal to the first Bluetooth communication module and the charging chip respectively.

[0099] When the first temple and the second temple are not connected to the cable 40 , the signal detected by the power meter is transmitted to the main processor through the first Bluetooth communication module and the second Bluetooth communication module.

[0100] When the first temple and the second temple are connected to the cable 40, the signal detected by the power meter is transmitted to the main processor through the charging chip, the first communication terminal, the third communication terminal, the communication line, the fourth communication terminal, and the second communication terminal, so that the main processor can know the battery power.

[0101] In some embodiments of the present application, a first speaker and a first speaker driving module are also provided in the first temple. The first speaker driving module drives the first speaker to make a sound. The first speaker driving module is electrically connected to the first Bluetooth communication module and the first communication terminal respectively.

[0102] When the first temple and the second temple are not connected to the cable 40, the first speaker driving module communicates with the main processor through the first Bluetooth communication module and the second Bluetooth communication module. The audio signal is transmitted to the second Bluetooth communication module of the second temple through the first Bluetooth communication module of the first temple, and finally reaches the main processor, thus solving the EMI problem of long-path transmission of high-noise audio signals.

[0103] When the first temple and the second temple are connected to the cable 40, the first speaker driving module communicates with the main processor through the first communication terminal, the third communication terminal, the communication line, the fourth communication terminal, and the second communication terminal. The audio signal between the first temple and the second temple is directly transmitted through the cable 40 for physical medium transmission, which greatly reduces the power consumption of the AR glasses when they are working for a long time.

[0104] The frame 30 is provided with a camera module, which includes an ET camera (eyetracking camera) for eye tracking, a 6Dof camera for motion tracking, and an RGB camera for perspective function.

[0105] The frame 30 is provided with a sensor module. The sensor module includes an inertial measurement module IMU, a Mag-sensor, a P-sensor, a hall-sensor, etc. The IMU and the Mag-sensor are used to cooperate with the camera module. The P-sensor and the hall-sensor are used to detect whether the user is wearing the glasses.

[0106] An optical machine module 31 is disposed on the frame 30 ; in this embodiment, the optical machine module is a color optical machine module.

[0107] A microphone is arranged on the frame; in this embodiment, the microphone is a digital microphone DMIC.
