Description

Technical Field

[0001] This application relates to the field of eyewear technology, specifically to a type of eyewear. Background Technology

[0002] In the interaction design of Augmented Reality (AR) glasses, the mainstream solution for achieving efficient and convenient human-computer interaction is to integrate touch sensors into the temples. However, due to the spatial constraints of the temples of smart AR glasses, the physical width of the touch area is generally narrow. Big data collection and analysis of user behavior show that most users tend to mistakenly place touch operations on the frame area during actual use.

[0003] However, due to the structural limitations of the hinge at the connection between the frame and temples, placing the touch sensor in the frame area would face the risk of contact instability caused by mechanical movement. The opening and closing of the hinge could lead to wear, displacement, or electrical connection failure of the sensor contacts, significantly reducing interaction reliability. Therefore, in related technologies, the touch sensor for AR glasses cannot be effectively deployed in the frame area and can only be concentrated in the temples. The limited physical space in the temples results in a narrow touch area, and the spatial mismatch between user operating habits and sensor layout leads to a significantly increased rate of accidental touches.

[0043] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Figure 1 This is a schematic diagram of the structure of eyeglasses provided in one embodiment of this application. Figure 1 As shown, the glasses include:

[0045] The temple 10 has a sensor 40 attached to its surface by nano-silver paste 50;

[0046] The frame 20 has a sensor 40 attached to its surface by nano-silver paste 50;

[0047] A spring pin connector 30 is located at the connection between the temple 10 and the frame 20, and is used to connect the pins on the temple 10 and the pins on the frame 20.

[0048] Figure 1 The diagram only shows a structural schematic of the temple and frame on one side of the glasses. It is understood that the temple and frame on the other side of the glasses may have the same or similar structure.

[0049] Figure 1 The dashed area in the figure represents the sprayed or printed nano-silver paste 50. Nano-silver paste is a functional electronic paste with high conductivity and printability, formed by dispersing nano-sized silver particles as conductive fillers in organic or inorganic solvents. It is widely used in flexible electronics, printed circuits, and sensors. The core characteristics of nano-silver paste lie in the quantum effect and interface effect of the nano-silver particles, which endow the paste with excellent conductivity, adhesion, and processing adaptability. It can be used to fabricate nanoscale electronic devices through coating or printing processes.

[0050] In one embodiment, the nano silver paste 50 can be sprayed or printed on the entire temple 10 and / or frame 20, or sprayed or printed on a portion of the temple 10 and / or frame 20, wherein it is necessary to ensure that the sprayed or printed nano silver paste 50 can adhere to each sensor 40.

[0051] Figure 1 The frame features a rectangular sensor 40. One or more sensors 40 can be attached to the temple 10 using nano-silver paste 50, and one or more sensors 40 can also be attached to the frame 20 using nano-silver paste 50. The sensors 40 can be located in any area of ​​the temple and frame. Optionally, for ease of user operation, they can be located in areas suitable for user operation.

[0052] By attaching the sensor 40 directly to the glasses using nano silver paste 50, the space required for flexible printed circuit boards (FPCs) inside the glasses cavity can be reduced, significantly reducing the user's learning time and ensuring touch control at any point on the temple.

[0053] A spring pin connector 30 is provided at the connection between the temple 10 and the frame 20. The connection between the temple 10 and the frame 20 has a pivot to facilitate the opening and closing of the temple 10. Figure 1The glasses shown are in the open position with temple 10 open, and spring pin connector 30 is connected but not visible. When temple 10 is closed, spring pin connector 30 is disconnected and visible.

[0054] In related technologies, in order to simultaneously install sensors on both the temple 10 and the frame 20, an FPC (Flexible Printed Circuit) needs to be installed at the hinge connection between the temple 10 and the frame 20 to achieve the circuit connection between them. However, it is impossible to insert the FPC into the hinge connection, which leads to a discontinuity in the sensor's response. When a finger touches the hinge connection, there will be no response.

[0055] In this embodiment, the pins on the temple 10 and the pins on the frame 20 are connected by the spring pin connector 30, which can realize the circuit connection between the temple 10 and the frame 20 without any sense of discontinuity and avoid repeated bending of the FPC.

[0056] The technical solution of this application embodiment is to set a spring pin connector at the connection between the temple and the frame, so that the pins on the temple and the frame can be effectively connected, so that the sensors on the temple and the frame can be connected. This solves the problem that setting the sensor only in the temple area results in a narrow touch area and a spatial mismatch between user operating habits and sensor layout, and can effectively reduce the accidental touch rate.

[0057] In one embodiment, Figure 2 This is a schematic diagram of a spring pin connector 30 provided in one embodiment of this application, as shown below. Figure 2 As shown, the spring pin connector 30 includes a pin seat 31 and a probe 32;

[0058] The pin holder 31 is disposed on one of the temple 10 and the frame 20;

[0059] The probe 32 is disposed on the other of the temple 10 and the frame 20;

[0060] The needle holder 31 and the probe 32 are conductive terminals;

[0061] The needle holder 31 and the probe 32 make elastic contact when the temple 10 is open.

[0062] The needle holder 31 and the probe 32 are similar in structure to a hinge. The needle holder 31 and the probe 32 are located at the pivot connection and are respectively mounted on the temple 10 and the frame 20. The needle holder 31 and the probe 32 are connected to the pins on the temple 10 and the pins on the frame 20, respectively.

[0063] The pin holder 31 and the probe 32 are in one-to-one correspondence. When the temple 10 is in the open state, the pin holder 31 and the probe 32 make elastic contact with each other. Both the pin holder 31 and the probe 32 are conductive terminals and have conductivity. Therefore, when the pin holder 31 and the probe 32 make elastic contact, the pins on the temple 10 and the pins on the frame 20 are connected in a circuit.

[0064] In one embodiment, Figure 3 This is a schematic diagram of the glasses provided in one embodiment of this application, as shown below. Figure 3 As shown, the glasses also include:

[0065] A touch chip 60 is attached to the temple 10 via nano silver paste 50;

[0066] The spring pin connector 30 is specifically used to connect the touch chip 60 on the temple 10 and the sensor 40 on the frame 20.

[0067] The touch chip 60 is an integrated circuit chip that integrates touch signal acquisition, processing, and recognition functions. By detecting changes in physical quantities such as capacitance and resistance, it can sense user touch operations and convert them into electrical signals for output. The core function of the touch chip is to realize the touch interaction function of electronic devices (such as mobile phones, tablets, AR glasses, etc.). It has characteristics such as high sensitivity, anti-interference and low power consumption, and is a core component of the touch system.

[0068] The touch chip 60 can be set on the temple 10 and connected to the sensor 40 on the temple 10 through nano silver paste, thereby obtaining the data collected by the sensor 40 on the temple 10.

[0069] The sensor 40, mounted on the frame 20, is connected to pins on the frame 20 via nano-silver paste 50. These pins are then connected to pins on the temple 10 via spring-loaded connectors 30. The pins on the temple 10 are also connected to the touch chip 60 via nano-silver paste 50. Therefore, the sensor 40 on the frame 20 can connect to the touch chip 60 on the temple 10 via the spring-loaded connectors 30, allowing the touch chip 60 on the temple 10 to acquire data collected by the sensor 40 on the frame 20.

[0070] In one embodiment, the glasses include a touch chip 60 attached to the frame 20 by a nano silver paste 50;

[0071] The spring pin connector 30 is specifically used to connect the touch chip 60 on the frame 20 and the sensor 40 on the temple 10.

[0072] The touch chip 60 can be set on the frame 20 and connected to the sensor 40 on the frame 20 through nano silver paste, thereby obtaining the data collected by the sensor 40 on the frame 20.

[0073] The sensor 40, mounted on the temple 10, is connected to pins on the temple 10 via nano-silver paste 50. These pins are then connected to pins on the frame 20 via spring-loaded connectors 30. The pins on the frame 20 are also connected to the touch chip 60 via nano-silver paste 50. Therefore, the sensor 40 on the temple 10 can connect to the touch chip 60 on the frame 20 via the spring-loaded connectors 30, allowing the touch chip 60 on the frame 20 to acquire data collected by the sensor 40 on the temple 10.

[0074] In one embodiment, the touch chip 60 includes flash memory, a microcontroller unit (MCU), random access memory (RAM), and read-only memory (ROM); the touch chip 60 is used to determine the touch position based on the capacitance signal collected by the sensor 40.

[0075] Flash memory is a non-volatile memory chip that retains data even after power is off. It supports fast erase and write operations and can be used to store firmware programs, calibration parameters, and user configuration information for touch chips.

[0076] The microcontroller unit (MCU) is the core computing engine of a touch chip, integrating components such as a central processing unit (CPU) and I / O interfaces. It is responsible for processing touch data, executing algorithm calculations, and generating control commands. MCUs are characterized by high real-time performance, low power consumption, and dedicated instruction set optimization, enabling them to quickly recognize touch positions, swipe paths, and multi-touch gestures, ensuring accurate and smooth touch response.

[0077] Random access memory (RAM) is a temporary data storage area for touch chips, used to temporarily store raw data collected in real time by touch sensors, intermediate results of algorithm calculations, and system operating status information.

[0078] Read-only memory (ROM) is a non-volatile memory that stores program code. It primarily stores the touch chip's startup program, basic input / output system (BIOS), and key algorithm libraries. The data is written to the chip during manufacturing and cannot be modified. ROM provides initialization instructions and basic operating logic for the microcontroller unit, ensuring that the system can automatically start and enter working state after power-on. It has high reliability and anti-interference capabilities, and is the fundamental guarantee for the stable operation of the touch chip.

[0079] When the sensor 40 is touched by a human body, it can generate a capacitance signal. The touch chip 60 can determine the touch position based on the capacitance signal collected by the sensor 40, and thus generate a corresponding instruction.

[0080] In one embodiment, sensor 40 is a touch sensor used to generate a capacitive signal when a human touches the touch sensor; the capacitive signal is used to determine the touch position.

[0081] The sensor 40 in this embodiment can be a touch sensor. A touch sensor is a detection device that can sense the contact or proximity of an object and convert it into an electrical signal. It uses capacitive, resistive, infrared, and other technical principles to capture information such as touch position, force, and movement trajectory in real time. Touch sensors can convert physical touch into digital signals, providing a human-computer interaction interface for electronic devices (such as touchscreens, smart wearables, and smart homes), and have characteristics such as high sensitivity, durability, and multi-touch support.

[0082] When a human touches the touch sensor, the touch sensor generates a capacitive signal. The touch sensor is electrically connected to the touch chip 60, and the capacitive signal generated by the touch sensor is transmitted to the touch chip 60. Based on the capacitive signal collected by the touch sensor, the touch chip 60 can determine the touch position and generate corresponding instructions.

[0083] A reference capacitance exists between sensor 40 and ground. When a finger touches the electrode, a touch capacitance is added, effectively creating a parallel touch capacitance. The change in capacitance after finger touch indirectly generates a voltage change. This voltage change is acquired by the ADC, amplified, and converted into a corresponding numerical value. Based on the changes in the digital values ​​on each electrode, the finger's position on the electrode is calculated. If the electrode only extends to the one-dimensional X direction, the X-coordinate calculation algorithm is as follows:

[0084] X = n * 255 + f (touch capacitor);

[0085] Where n is the number of electrode bits, indicating that the nth electrode is touched, and 255 represents the electrode resolution. The f() function represents the forward or backward offset of the finger; for example, if the finger moves forward, f() outputs a negative value, and if it moves backward, the output value is positive.

[0086] In one embodiment, a touch sensor attached to the temple 10 is disposed on the outer frame surface of the temple 10; a touch sensor attached to the frame 20 is disposed on the front frame surface of the glasses.

[0087] To facilitate touch operation by the user's fingers, touch sensors are placed on the outer frame surface of the temple 10 and the front frame surface of the glasses.

[0088] Understandably, when a user wears glasses, the side of the temple that contacts the user's head is the inner frame surface of the temple, while the side opposite the inner frame surface is the outer frame surface of the temple 10. For example... Figure 1 As shown, the sensor 40 on the temple 10 is disposed on the outer frame surface of the temple 10.

[0089] The front surface of eyeglasses refers to the front of the glasses, which is the surface that is almost parallel to the lenses.

[0090] Optionally, such as Figure 1 As shown, the touch sensor attached to the frame 20 can also be placed on the side of the front frame of the glasses.

[0091] By placing touch sensors on the outer frame surface of the temple 10 and the front frame surface of the glasses, user operation can be facilitated.

[0092] In one embodiment, Figure 4 This is a schematic diagram of the sliding start area and the click area provided in an embodiment of this application; as shown... Figure 4 As shown, a sliding start area is provided in the area near the temple 10 of the frame 20; a click area is provided at the end of the temple 10.

[0093] Figure 4 The dotted circles in the diagram correspond to the sliding start area and the click area, respectively. Setting the sliding start area within the frame 20 near the temple 10 was determined through human factors testing and surveys. Similarly, setting the click area at the end of the temple 10 was also determined through human factors testing and surveys.

[0094] Because it is necessary to take into account both the sliding start area and the click area, it is necessary to ensure that the temple 10 and the frame 20 can be connected by circuitry. Therefore, a spring pin connector 30 is provided at the connection between the temple 10 and the frame 20.

[0095] In one embodiment, the glasses are augmented reality glasses.

[0096] In one embodiment, the augmented reality glasses may include any one or more of the following:

[0097] Display screen;

[0098] Waveguide sheet;

[0099] Light engine;

[0100] Signal amplification unit;

[0101] Signal acquisition and storage unit;

[0102] Central processing unit.

[0103] The display screen can include a physical display screen and a virtual display screen. The physical display screen includes an optical display module, including an optical combiner. The optical display module includes an optomechanical system and an optical coupler, which can be based on an optical waveguide or a semi-reflective translucent lens. In one embodiment, the optical combiner is disposed on the spectacle lens, i.e., all or part of the spectacle lens. The virtual display screen is generated in front of the viewer's eyes after the light emitted from the optomechanical system of the physical display screen has undergone multiple propagation and transformations. The virtual display screen is located within the viewer's actual field of vision and is used to overlay and display various virtual information.

[0104] Waveguides are the core optical components of augmented reality glasses. They use optical waveguide technology to confine the image beam projected by the optical engine within the thin sheet, and transmit it to the human eye through the principle of total internal reflection. During the transmission process, the beam is expanded and homogenized, ultimately forming a virtual image that can cover the human eye's field of vision.

[0105] The light engine is the image generation source for augmented reality glasses. It integrates a microdisplay (such as OLED or LCoS), an illumination system, and optical modulation elements. It is responsible for converting electrical signals into high-brightness, high-resolution image light signals and accurately projecting them onto the waveguide input.

[0106] The signal amplification unit is the electrical signal amplification module of augmented reality glasses. Through circuit components such as operational amplifiers and power amplifiers, it amplifies weak sensor signals (such as touch signals, inertial measurement unit (IMU) outputs) or communication signals (such as Bluetooth / WiFi) to meet the input requirements of subsequent circuits.

[0107] The central processing unit is the computing core of augmented reality glasses. It typically uses a low-power SoC (System-on-a-Chip) or a dedicated AI chip, integrating a CPU (responsible for system control), a GPU (rendering 3D images), and an NPU (processing AI algorithms) to work together to complete AR content rendering, spatial computing, and interactive logic processing.

[0108] It should be noted that this utility model is not limited to the above-described embodiments. Other changes can be made according to the concept principles of this utility model. All such changes made in accordance with the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
