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 most likely product to replace mobile phones in the future. Due to weight and volume restrictions, there is little space left for circuit boards. In addition, color optical machines, various detection cameras (up to 5 or more), and various detection sensors are distributed on the front frame of the glasses, which means that there are hundreds of connection signals between the front frame and the left temple main board. Since the signals of cameras and optical machines are all high-speed signals, impedance matching requirements are required on the flexible circuit board. High-speed signals need to be grounded up and down, left and right. This requires 4 or more layers of flexible circuit boards to accommodate hundreds of high-speed and low-speed signals, and the thickness can reach more than 0.25mm. Therefore, the flexible circuit board will become extremely hard. After such a thick flexible circuit board passes through the bending area of ​​the temple, it cannot withstand multiple folding of the temple (the copper skin of the flexible circuit board will be broken after folding one or two hundred times in the experiment), so it is impossible to truly achieve full life cycle reliability. Moreover, since the flexible circuit board needs to reserve a bending area, the routing loop of the high-speed signal will be very long, which can easily lead to signal integrity and EMI problems.

[0004] The current solution on the market is to use Air-gap technology of flexible circuit boards (each layer is an independent flexible circuit board, the thickness can be as high as 0.1mm per layer, and it has good flexibility) to disperse the stress of bending, thereby increasing the number of bending times. However, this type of technology cannot guarantee the continuity of the impedance reference of high-speed signals. The quality of high-speed signals will deteriorate, causing frame drops in cameras and optical machine images. Performance can only be sacrificed to increase the number of bending times.

[0005] Therefore, the current AR glasses have poor reliability in signal transmission between the frames and temples, which may lead to incomplete signal transmission. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0074] The AR glasses of this embodiment include a first temple 10, a second temple 20, a frame 40, etc. Figures 1 to 5 shown.

[0075] The first temple 10 has a first connecting piece and a first conductive part at the end of its shell.

[0076] The second temple 20 has a second connecting member 21 and a second conductive portion 22 at the end of the housing.

[0077] The frame 40 has a third connecting member and a third conductive portion at one end of its housing, and a fourth connecting member 41 and a fourth conductive portion 42 at the other end of its housing.

[0078] The third connecting member is rotatably connected to the first connecting member, so as to realize the rotatable connection between the first temple 10 and the frame 40, and the first temple 10 can be opened or folded. The fourth connecting member 41 is rotatably connected to the second connecting member 21, so as to realize the rotatable connection between the second temple 20 and the frame 40, and the second temple 20 can be opened or folded.

[0079] When the first temple 10 is opened, the first conductive portion contacts the third conductive portion, and the first conductive portion and the third conductive portion can transmit electrical signals to achieve communication between the first temple 10 and the frame 40 .

[0080] When the first temple 10 is folded, the first conductive portion is separated from the third conductive portion and disconnected, and the first conductive portion and the third conductive portion stop transmitting electrical signals.

[0081] When the second temple 20 is opened, the second conductive portion 21 contacts the fourth conductive portion 41 , and the second conductive portion 21 and the fourth conductive portion 41 can transmit electrical signals to achieve communication between the second temple 20 and the frame 40 .

[0082] When the second temple 20 is folded, the second conductive portion 21 is separated from the fourth conductive portion 41 and disconnected, and the second conductive portion 21 and the fourth conductive portion 41 are disconnected from each other, and the electrical signal transmission is cut off.

[0083] Therefore, when the first temple 10 is opened, electrical signals are transmitted between the first temple 10 and the frame 40 through the first conductive portion and the third conductive portion.

[0084] When the second temple 20 is opened, electrical signals are transmitted between the second temple 20 and the frame 40 via the second conductive portion 21 and the fourth conductive portion 41 .

[0085] The AR glasses of this embodiment are designed with a first connector and a first conductive part at the shell end of the first temple 10, a second connector 21 and a second conductive part 22 at the shell end of the second temple 20, a third connector and a third conductive part at one end of the shell of the frame 40, and a fourth connector 41 and a fourth conductive part 42 at the other end of the shell of the frame 40; when the first temple 10 is opened, the first conductive part contacts with the third conductive part to achieve communication between the first temple 10 and the frame 40; when the second temple 20 is opened, the second conductive part 21 contacts with the fourth conductive part 41 to achieve communication between the second temple 20 and the frame 40. communication between them; since the signal transmission between the first temple 10 and the frame 40 is achieved through the contact connection between the first conductive part and the third conductive part, the signal transmission between the second temple 20 and the frame 40 is achieved through the contact connection between the second conductive part and the fourth conductive part, the risk of breakage of the flexible circuit board due to multiple bending in the prior art is eliminated, and the signal routing length is greatly reduced, the long path signal loss is reduced, the signal integrity is enhanced, and the reliability of the signal transmission between the frame and the temple is enhanced, which solves the technical problem of poor reliability of signal transmission between the frame and the temple in the prior art, ensures the integrity of the signal transmission, and reduces the EMI risk.

[0086] The AR glasses of this embodiment realize the modularization of AR glasses, which can be assembled and repaired and replaced more easily, greatly enhancing the mass production of AR glasses, having strong practicality and huge market potential. When the first temple or the second temple is damaged, the damaged temple can be directly replaced, which is convenient for maintenance.

[0087] 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.

[0088] In some embodiments of the present application, the AR glasses further include a first rotating component and a second rotating component; the first connecting member is connected to the third connecting member through the first rotating component, and the second connecting member 21 is connected to the fourth connecting member 41 through the second rotating component.

[0089] The first rotating assembly includes a first rotating plate and a first rotating shaft; the first rotating plate is rotatably connected to the first rotating shaft, the first connecting member is fixedly connected to the first rotating plate, and the third connecting member is fixedly connected to the first rotating shaft. When the first rotating plate rotates, the first connecting member is driven to rotate, thereby realizing the rotatable connection between the first connecting member and the third connecting member, which is simple, reliable, easy to realize, and low in cost.

[0090] The second rotating assembly includes a second rotating plate 31 and a second rotating shaft 32, see Figure 1 , Figure 2As shown, the second rotating plate 31 is rotatably connected to the second rotating shaft 32, the second connecting member 21 is fixedly connected to the second rotating plate 31, and the fourth connecting member 41 is fixedly connected to the second rotating shaft 32. When the second rotating plate 31 rotates, the second connecting member 21 is driven to rotate, thereby realizing the rotatable connection between the second connecting member 21 and the fourth connecting member 41, which is simple, reliable, easy to implement, and low in cost.

[0091] In some embodiments of the present application, the first connecting member has a first contact surface, and the first conductive portion is recessed / convexly arranged on the first contact surface; the second connecting member 21 has a second contact surface, and the second conductive portion 22 is recessed / convexly arranged on the second contact surface; the third connecting member has a third contact surface, and the third conductive portion is convexly / concavely arranged on the third contact surface; the fourth connecting member 41 has a fourth contact surface, and the fourth conductive portion 42 is convexly / concavely arranged on the fourth contact surface.

[0092] When the first temple is opened and the first contact surface contacts the third contact surface, the first conductive part contacts and connects with the third conductive part, and the two can transmit electrical signals.

[0093] When the first temple is folded and the first contact surface is separated from the third contact surface, the first conductive portion is disconnected from the third conductive portion.

[0094] When the second temple is opened and the second contact surface contacts the fourth contact surface, the second conductive part contacts and connects with the fourth conductive part, and the two can transmit electrical signals.

[0095] When the second temple is folded and the second contact surface is separated from the fourth contact surface, the second conductive portion is disconnected from the fourth conductive portion.

[0096] The contact surface plays a role of limiting, and the conductive part is arranged concavely or convexly on the contact surface. When the two contact surfaces are in contact, the conductive parts on the two contact surfaces are in contact and connected, thereby avoiding damage to the conductive part and ensuring the connection reliability between the two conductive parts.

[0097] For example,

[0098] The first conductive part is recessed on the first contact surface, and correspondingly, the third conductive part is protruding on the third contact surface.

[0099] The second conductive part is recessed on the second contact surface, and correspondingly, the fourth conductive part is protruding on the fourth contact surface.

[0100] In some embodiments of the present application, the first conductive part includes n conductive terminals, and correspondingly, the third conductive part also includes n conductive terminals, where n≥1.

[0101] The conductive terminal of the first conductive part is a pin seat of a spring pin connector, and the conductive terminal of the third conductive part is a probe of the spring pin connector; the top of the probe has a certain elasticity. When the first temple is opened, the n conductive terminals of the first conductive part are in elastic contact with the n conductive terminals of the third conductive part in a one-to-one correspondence.

[0102] Therefore, n spring pin connectors are designed between the first temple 10 and the frame 40 , wherein the n pin seats are the n conductive terminals of the first conductive part, and the n probes are the n conductive terminals of the third conductive part.

[0103] In some embodiments of the present application, the second conductive portion includes m conductive terminals, and correspondingly, the fourth conductive portion also includes m conductive terminals, where m≥1.

[0104] The conductive terminal of the second conductive part is a pin seat of a spring pin connector, and the conductive terminal of the fourth conductive part is a probe of the spring pin connector; the top of the probe has a certain elasticity. When the second temple is opened, the m conductive terminals of the second conductive part are in elastic contact with the m conductive terminals of the fourth conductive part in a one-to-one correspondence.

[0105] Therefore, m spring pin connectors are designed between the second temple 20 and the frame 40, wherein the m pin seats are the m conductive terminals of the second conductive part, and the m probes are the m conductive terminals of the fourth conductive part.

[0106] 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, such as Figure 3 The probe shown. The use of a spring pin connector facilitates good contact and a certain amount of contact expansion, preventing the spring pin connector from generating excessive stress and causing damage to the product when the glasses fall.

[0107] By using a spring pin connector in the AR glasses, the stability and reliability of signal transmission between the frame 40 and the first glasses 10 and the second glasses 20 are ensured.

[0108] The number of spring pin connectors is selected according to the number of signal connections at the bends of the first temple 10, the second temple 20 and the frame 40. The spring pin connectors are gold-plated and impedance-controlled so that there is no signal loss problem when the temples are connected to the frame.

[0109] In the AR glasses of this embodiment, the first temple 10, the second temple 20, and the frame 40 independently form modules, and the three are only interconnected by a spring pin connector, which is conducive to the assembly and maintenance of large-scale mass production of AR glasses and reduces the difficulty of assembly and maintenance costs.

[0110] In some embodiments of the present application, in order to facilitate the detection of whether the first temple 10 and the second temple 20 are folded and to facilitate power supply, the first conductive part, the second conductive part, the third conductive part, and the fourth conductive part all include a folding detection terminal (conductive terminal) and a power supply terminal (conductive terminal).

[0111] A charging chip (Charger IC) and a battery are arranged in the housing of the first temple 10. Figure 5 As shown, the charging chip charges the battery, the ADC detection pin of the charging chip is connected to a DC power supply (such as a 5V power supply, which can be provided by a battery) through a first resistor R1, the ADC detection pin of the charging chip is connected to the folding detection terminal of the first conductive part, and the energy output pin of the charging chip is connected to the power supply terminal of the first conductive part.

[0112] A mainboard is arranged in the shell of the second temple 20, an ADC detection pin of the mainboard is grounded through a second resistor R2, the ADC detection pin of the mainboard is connected to a folding detection terminal of the second conductive part, and a power receiving pin of the mainboard is connected to a power supply terminal of the second conductive part.

[0113] The folding detection terminals and the power supply terminals of the third conductive part are electrically connected to the folding detection terminals and the power supply terminals of the fourth conductive part in a one-to-one correspondence.

[0114] When the first temple 10 is opened, the folding detection terminals and the power supply terminals of the first conductive part are in contact with the folding detection terminals and the power supply terminals of the third conductive part in a one-to-one correspondence.

[0115] When the second temple 20 is opened, the folding detection terminals and the power supply terminals of the second conductive part are in contact with the folding detection terminals and the power supply terminals of the fourth conductive part in a one-to-one correspondence.

[0116] Therefore, when the first temple is opened and the second temple is opened, the ADC detection pin of the charging chip is connected to the ADC detection pin of the mainboard through the folding detection terminal of the first conductive part, the folding detection terminal of the third conductive part, the folding detection terminal of the fourth conductive part, and the folding detection terminal of the second conductive part. The energy output pin of the charging chip is connected to the power receiving pin of the mainboard through the power supply terminal of the first conductive part, the power supply terminal of the third conductive part, the power supply terminal of the fourth conductive part, and the power supply terminal of the second conductive part.

[0117] When the first temple and the second temple are both opened, the voltage detected by the ADC detection pin of the charging chip and the ADC detection pin of the mainboard is U1*R2 / (R1+R2). U1 is the voltage of the DC power supply, such as U1=5V, R1=3Ω, and R2=2Ω.

[0118] When the first temple or the second temple is folded, the voltage detected by the ADC detection pin of the charging chip is U1, and the voltage detected by the ADC detection pin of the mainboard is 0. The energy output pin of the charging chip disconnects the energy output to the frame and the second temple, and the AR glasses are turned off.

[0119] Therefore, when the user opens the first temple and the second temple, the ADC detection pin (detection sampling voltage) of the charging chip and the ADC detection pin (detection sampling voltage) of the mainboard detect that the voltage division of the first resistor R1 and the second resistor R2 is correct, and the AR glasses automatically turn on, making it convenient for users to use.

[0120] When the user takes off the glasses and folds them, the first temple (with a battery inside) bends first. Since VPH-power is the power supply for the entire AR glasses, the power supply is disconnected and the mainboard is powered off and shut down.

[0121] When the second temple (with the main board inside) bends first, the voltage on the resistor R1 of the first temple (ADC detection) will be abnormal, and the first temple will determine that the second temple has been disconnected. The charger IC will also automatically control the prohibition of outputting VPH-power to ensure the safety of the AR glasses.

[0122] The housing of the first temple 10 is also provided with a USB connector 43, which is connected to a charging chip (charger IC). Figure 4 , Figure 5 When the first temple or the second temple is folded, the USB connector 43 can be used to charge the battery in the first temple alone.

[0123] In some embodiments of the present application, in order to facilitate the mainboard to obtain the battery power, the first conductive part, the second conductive part, the third conductive part, and the fourth conductive part all include a power detection terminal.

[0124] A power meter is also provided in the housing of the first temple 10, and the power meter detects the power level of the battery. The output pin of the power meter is connected to the power detection terminal of the first conductive part, and the detected power signal is sent to the power detection terminal of the first conductive part.

[0125] The power detection pin of the main board of the second temple 20 is connected to the power detection terminal of the second conductive part.

[0126] The electric quantity detection terminal of the third conductive part is electrically connected to the electric quantity detection terminal of the fourth conductive part.

[0127] When the first temple 10 is opened, the power detection terminal of the first conductive part contacts the power detection terminal of the third conductive part.

[0128] When the second temple 20 is opened, the electric quantity detection terminal of the second conductive part contacts the electric quantity detection terminal of the fourth conductive part.

[0144] In some embodiments of the present application, in order to facilitate the transmission of optical-mechanical signals between the frame and the second temple, the second conductive portion and the fourth conductive portion both include optical-mechanical signal transmission terminals.

[0145] The frame 40 is provided with an optical-mechanical module 44, which is connected to the optical-mechanical signal transmission terminal of the fourth conductive portion. In this embodiment, the optical-mechanical module is a color optical-mechanical module.

[0146] The MIPI pin of the mainboard of the second temple 20 is connected to the optical-mechanical signal transmission terminal of the second conductive part.

[0162] The AR glasses of this embodiment separate the frame, the first temple, and the second temple into three parts, and connect the three parts to each other through customized micro pogo pins, thereby enhancing the bending reliability of the temple signal of the AR glasses and making the AR glasses more practical and mass-producible.

[0163] The AR glasses of this embodiment customize high-speed signal connectors (i.e., pogo pins) that meet impedance matching according to the number of signals at the bends between the temples and the frame, so that the signal connection between the temples and the frame is directly connected through the pogo pins, eliminating the risk of breakage caused by multiple bends of the FPC in the prior art. In addition, the use of the pogo pin direct connection solution also greatly reduces the length of the high-speed signal routing (the prior art requires a longer FPC reserved bend), reduces long-path signal loss, enhances signal integrity, and reduces EMI risks.
