[0018] Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to those processes, methods, products, or apparatuses.

[0019] This application provides a temperature control device, method, and AR glasses for AR glasses, which will be described below with reference to the accompanying drawings.

[0020] Please refer to Figure 1 This illustration shows a structural schematic diagram of a temperature control device for AR glasses provided in an embodiment of this application. Figure 1 As shown, the temperature control device for AR glasses provided in this application may specifically include: a temperature control module 10, a temperature detection module 20, a controller 30, and a wear detection module 40.

[0021] The temperature control module 10 integrates a piezoelectric fan, which is small in size, light in weight, and low in energy consumption, and can provide a stable airflow without increasing the burden of wearing AR glasses.

[0022] The temperature control module 10 is located on the inner side of the connection between the temple and the lens of the AR glasses, and the temperature control module 10 is provided with an air outlet. The air outlet is located on the inner side near the connection between the temple and the lens. This position does not affect the normal wearing and appearance of the AR glasses, and ensures that the airflow blown out of the air outlet is accurately applied to the user's face.

[0023] Furthermore, such as Figure 2 As shown, there are two temperature control modules 10, respectively located on the left and right temples of the AR glasses, designated as left temperature control module 11 and right temperature control module 12. Each temperature control module 10 is signal-connected to the controller 30, ensuring that the controller can independently control the operating status of each temperature control module. Figure 3 The diagram shows the location distribution of the air outlets, as follows: Figure 4The diagram shows the coverage area of ​​the air vents. The air vent F1 on the left temple of the glasses points downwards to the right (denoted as S1), and the air vent F2 on the right temple points upwards to the left (denoted as S2). The airflow from the two vents together forms a diamond-shaped area covering the entire face, which can fully cover the user's face, accelerate the air circulation around the face, ensure that all areas of the face can obtain a good cooling effect, and greatly improve the user's wearing comfort.

[0024] The wear detection module 40 is used to detect whether the user is wearing AR glasses, obtain wear detection data and report it to the controller 30, so as to provide a basis for the controller to control the start and stop of each module.

[0025] In some embodiments, the wear detection module 40 includes at least one infrared sensor, which determines whether the user is wearing AR glasses by detecting infrared radiation from human skin, with high detection accuracy and fast response speed.

[0026] The temperature detection module 20 is used to detect the ambient temperature around the user's face in real time and report it to the controller 30. Specifically, when the wear detection module detects that the user is wearing AR glasses, the temperature detection module 20 detects the ambient temperature around the face at preset time intervals and reports the ambient temperature to the controller in real time, ensuring that the controller can obtain the facial temperature changes in a timely manner. The preset time t can be set according to actual usage needs, such as 1 second, 2 seconds, etc.

[0027] In some embodiments, the temperature detection module 20 includes at least one temperature sensor, which is a high-precision ambient temperature sensor capable of detecting the ambient temperature around the user's face in real time and accurately.

[0028] The controller 30 uses a microprocessor and has pre-stored different temperature control levels and corresponding temperature thresholds. Users can set different temperature control levels Lx (e.g., three temperature control levels, namely low, medium, and high) and corresponding temperature thresholds Tx (e.g., the temperature threshold for low level is 30℃, the temperature threshold for medium level is 32℃, and the temperature threshold for high level is 34℃) through the AR glasses' operating interface according to their own needs.

[0029] The controller 30 is used to control the opening and closing of the temperature control module 10 based on the wear detection data, the ambient temperature, and the different temperature control levels and corresponding temperature thresholds.

[0030] Specifically, the control logic of controller 30 is as follows: The controller 30 first determines whether the user is wearing AR glasses based on the wear detection data. When AR glasses are detected, the controller 30 receives the ambient temperature Tm reported by the temperature detection module 20 and compares it with pre-stored temperature thresholds Tx to determine the target temperature control level. For example, when the ambient temperature Tm reaches 30℃ but is below 32℃, a low temperature control level is matched; when the ambient temperature Tm reaches 32℃ but is below 34℃, a medium temperature control level is matched; and when the ambient temperature Tm reaches 34℃ or above, a high temperature control level is matched. Subsequently, the controller 30 sends an airflow control command including the target temperature control level to the temperature control module. The piezoelectric fan of the temperature control module generates an airflow corresponding to the target temperature control level (low level corresponds to a small airflow, medium level to a medium airflow, and high level to a large airflow). When the ambient temperature Tm is below the minimum temperature threshold Tx (e.g., 30℃ in the example above), the controller 30 controls the temperature control module to shut down to avoid energy waste and achieve intelligent control.

[0031] This application also provides an AR glasses device equipped with the temperature control device for AR glasses described in the above embodiments. While retaining the original entertainment, audio-visual, navigation, and business functions, this AR glasses adds a facial temperature control function, effectively solving the problem of excessively high facial temperature when worn outdoors in summer, thus improving the user experience.

[0032] This application also provides a temperature control method based on the temperature control device described in the above embodiments, including the following steps: S1: After the user puts on the AR glasses, the wearing detection module detects the wearing status and triggers the temperature detection module to start. Specifically, the infrared sensor of the wearing detection module detects the infrared radiation of the human skin, determines that the user is wearing AR glasses, and reports the wearing detection data to the controller. After receiving the wearing detection data, the controller sends a start command to the temperature detection module, triggering the temperature detection module to start.

[0033] S2: The temperature detection module detects the ambient temperature around the face at preset time intervals and reports the ambient temperature to the controller. The temperature detection module continuously detects the ambient temperature Tm around the face at preset time intervals t and transmits the detected temperature data to the controller in real time. The controller stores and processes the temperature data.

[0034] S3: Users can set different temperature control levels and corresponding temperature thresholds. Through the AR glasses' interface, users can set multiple temperature control levels Lx and the corresponding temperature threshold Tx for each level according to their own usage needs and comfort preferences. After setting, these parameters are stored in the controller.

[0035] S4: The controller compares the ambient temperature with temperature thresholds, matches the corresponding target temperature control level, and sends an airflow control command including the target temperature control level to the temperature control module. The temperature control module generates an airflow corresponding to the target temperature control level, which is then blown onto the face through the air outlet, forming a diamond-shaped coverage area. The controller compares the received ambient temperature Tm with each temperature threshold Tx one by one, finds the matching temperature control level as the target temperature control level, and then sends an airflow control command to the temperature control modules on both sides. The piezoelectric fans of the temperature control modules generate an airflow of the corresponding level according to the command. The airflow is blown onto the face through the air outlet, and the airflow from the two air outlets forms a diamond-shaped coverage area, accelerating air circulation around the face and reducing the perceived temperature of the face.

[0036] S5: When the ambient temperature is below the minimum temperature threshold, the controller shuts down the temperature control module. The controller monitors changes in the ambient temperature Tm in real time. When it detects that Tm is below the minimum temperature threshold Tx, it sends a shutdown command to the temperature control module, causing the module to stop operating and avoiding unnecessary energy consumption, thus achieving intelligent energy-saving control.

[0037] For ease of understanding, this application also provides a specific implementation process of the temperature control method, such as... Figure 5 As shown: 1) AR glasses store facial temperature parameters and set different temperature control levels; When a user wears AR glasses, the temperature sensor starts working, detecting the ambient temperature around the face every t time interval and reporting the ambient temperature Tm to the microprocessor, which then stores the ambient temperature parameters.

[0038] Users can set different temperature control levels Lx and corresponding temperature thresholds Tx according to their needs.

[0039] 2) Trigger the temperature control module to adjust the facial ambient temperature; The microprocessor processes the stored facial ambient temperature information, comparing the ambient temperature around the face with different temperature thresholds Tx to match the corresponding temperature control level Lx. Then, it notifies the temperature control modules on the left and right temples of the glasses to generate the corresponding level of airflow. This airflow flows out through the air outlets of the temperature control devices on the inside of the left and right temples and blows towards the front of the user's face, forming a diamond-shaped facial coverage area. This accelerates air circulation around the face, reduces the perceived temperature of the face while wearing AR glasses, and greatly improves user comfort.

[0040] When the ambient temperature of the face is lower than the set temperature threshold, the temperature control module will not be turned on or off, making it more intelligent.

[0041] Compared to existing technologies, the temperature control device for AR glasses provided in this application achieves intelligent regulation of the facial ambient temperature during AR glasses wear by setting up a temperature control module, a temperature detection module, a controller, and a wear detection module. The temperature control module integrates a piezoelectric fan and is located inside the connection between the temple and the lens. With a specific air outlet orientation, it can form a diamond-shaped airflow area covering the entire face, effectively accelerating air circulation around the face and reducing the perceived temperature. The wear detection module can accurately identify the user's wearing status, preventing the device from malfunctioning when not wearing the glasses. The temperature detection module collects the facial ambient temperature in real time, and the controller intelligently matches the temperature control level and controls the start / stop of the temperature control module and the airflow adjustment based on the comparison results of the temperature data and preset thresholds. The entire device has a simple structure and reasonable design, does not affect the original appearance and wearing comfort of the AR glasses, and can adjust the facial ambient temperature in real time and accurately, significantly improving the user experience of wearing AR glasses in high-temperature environments. It has good practicality and promotional value.
