[0024] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0025] FIG1 shows a schematic diagram of the structure of smart glasses according to an embodiment of the present disclosure.

[0026] Referring to FIG1 , the smart glasses provided by the present disclosure include a frame 10, temples 11, and a hinge 12. The frame 10 and temples 11 are connected by the hinge 12, so that the temples 11 can rotate relative to the frame 10 along the hinge 12. In addition, the smart glasses also include a battery power module (not shown in the figure), a detection module (not shown in the figure), and a control module (not shown in the figure). The battery power module and the detection module are respectively connected to the control module. The battery power module is also connected to the main processor of the smart glasses to power the operation of the main processor of the smart glasses. The detection module is used to detect the opening and closing state of the temples 11, that is, to detect whether the temples 11 are in an open state or a folded / semi-folded state, and to generate a corresponding detection signal based on the detected opening and closing state of the temples 11. The detection signal represents the state of the temples 11. The detection module transmits the generated detection signal to the control module. The control module determines the opening and closing state of the temples 11 based on the detection signal, so as to control the battery power module to supply power to the main processor. In this way, the main processor can be powered automatically according to the opening and closing status of the temples 11, and the smart glasses can be turned on without the need for user operation.

[0027] The control module in this application uses a microcontroller (MCU) module that is independent of the main processor of the smart glasses, preferably an ultra-low-power MCU such as the STM32L011E3 and STM32L011E4. The current consumed by the microcontroller MCU module independent of the main processor is only a few microamperes. In comparison, the power consumption of the main processor of the smart glasses is at least 1000 times that of the MCU. If the main processor of the smart glasses is used to manage the power on and off of the smart glasses, the standby time will be greatly reduced. Therefore, this application uses a microcontroller MCU independent of the main processor to manage the power on and off of the smart glasses, which can effectively reduce the energy consumption of the smart glasses and extend the use time of the smart glasses.

[0028] In one embodiment, when the detection module detects that the temples 11 have been rotated to a fully open state, indicating that the smart glasses are about to be worn or have been worn, the detection module generates a first detection signal and sends it to the control module. After receiving the first detection signal, the control module determines that the temples 11 of the smart glasses are now in a fully open state, and the control module controls the battery power module to supply power to the main processor of the smart glasses. When the detection module detects that the temples 11 have been rotated to a fully folded state or a semi-folded state, indicating that the smart glasses are not being worn, the detection module generates a second detection signal and sends it to the control module. After receiving the second detection signal, the control module determines that the temples 11 of the smart glasses are not in a fully open state, and the control module controls the battery power module to stop supplying power to the main processor of the smart glasses.

[0029] FIG2 shows a schematic diagram of the switch control logic of a pair of smart glasses according to an embodiment of the present disclosure; FIG3 shows a schematic diagram of the switch control circuit structure of a pair of smart glasses according to an embodiment of the present disclosure.

[0030] Referring to Figures 2 and 3, the smart glasses further include a switch module, which is connected to the control module. The switch module has an input connected to the battery power module, and an output connected to the main processor of the smart glasses. After the detection module detects that the temple 11 rotates to a fully open state and generates a first detection signal, the control module controls the switch module to be turned off and on based on the first detection signal, and the battery power module supplies power to the main processor. After the detection module detects that the temple 11 rotates to a fully folded state or a partially folded state and generates a second detection signal, the control module controls the switch module to be turned off and off based on the second detection signal, and the battery power module stops supplying power to the main processor.

[0031] In one embodiment, the smart glasses further include a sensing module for sensing whether the smart glasses are being worn. The sensing module may be a sensing sensor and may be disposed at any location on the frame 10 or temple 11 of the smart glasses. It is understood that to make the smart glasses more aesthetically pleasing, the sensing module may be disposed within the temple 11 or the inner cavity of the frame 10.

[0032] In one embodiment, the smart glasses further include a timing module, which is connected to the control module. When the detection module detects that the temple 11 is rotated to a fully open state, the timing module starts timing, and a time threshold can be set in advance. When the timing duration of the timing module is greater than or equal to the preset time threshold and the sensing module senses that the smart glasses are not worn within the timing duration, the timing module generates a third detection signal, and the timing module transmits the third detection signal to the control module, and the control module controls the battery power module to stop supplying power to the main processor.

[0033] After the timing module starts timing, if the sensing module senses that the smart glasses are being worn within a preset time threshold, the timing module resets to zero. When the sensing module senses that the smart glasses are being taken off and are not being worn but the temples 11 are still in the fully open state, the timing module restarts timing.

[0034] It is understandable that when the control module has a timing function, the function of the timing module can be replaced by the control module to optimize the structure of the smart glasses.

[0035] In one embodiment, the smart glasses further include a physical button. When the detection module detects that the temple 11 has been rotated to a fully open position, a first detection signal is generated. The control module then controls the battery power module to supply power to the main processor based on the first detection signal. However, if the user has merely rotated the temple 11 to an open position but is not wearing the smart glasses, the physical button can be manually pressed to prevent wasted power consumption, causing the battery power module to stop supplying power to the main processor of the smart glasses. Furthermore, if the detection module detects that the temple 11 has been rotated to an open position and the sensing module senses that the smart glasses are being worn, the control module also controls the battery power module to supply power to the main processor of the smart glasses. However, if the user is merely wearing the smart glasses and does not need to use any of the smart glasses' functions, the physical button can also be manually pressed to cause the battery power module to stop supplying power to the main processor of the smart glasses. When the user needs to use any of the smart glasses' functions, the user can press the physical button to cause the battery power module to supply power to the main processor of the smart glasses. In this way, when using any of the smart glasses' functions, the user does not need to remove the smart glasses and then rotate the temple 11 again to cause the battery power module to supply power to the main processor, thereby facilitating user operation.

[0036] It can be understood that the physical button can be installed at any position of the frame 10 and the temple 11, and a suitable position can be selected for installation according to the shape and structure of the smart glasses. To facilitate user operation, preferably, the physical button can be installed on the outer surface side of the smart glasses.

[0037] FIG4 shows a second schematic diagram of the structure of smart glasses according to an embodiment of the present disclosure.

[0038] Referring to FIG2 , the detection module 13 comprises a Hall switch 131 and a magnet 132. When the temple 11 rotates relative to the frame 10 on the hinge 12, the distance between the magnet 132 and the Hall switch 131 changes with the rotation of the temple 11. The output level of the Hall switch 131 changes with the distance from the magnet 132. The greater the distance between the Hall switch 131 and the magnet 132, the lower the output level of the Hall switch 131. The Hall switch 131 is connected to the control module. Based on the output level of the Hall switch 131, the control module controls the battery power module to supply power to the main processor.

[0039] The Hall switch 131 is placed on the inner side of the end of the temple 11 connected to the frame 10, and the magnet 132 is placed on the inner side of the end of the frame 10 connected to the temple 11. When the temple 11 is rotated to a fully open state, the magnet 132 is away from the Hall switch 131, and the Hall switch 131 outputs a low-level signal to the control module, and the control module controls the battery power supply module to supply power to the main processor; but when the temple 11 is rotated to a fully folded state or a semi-folded state, the magnet 132 is close to the Hall switch 131, and the Hall switch 131 outputs a high-level signal to the control module, and the control module controls the battery power supply module to stop supplying power.

[0040] It is understood that the Hall switch 131 and the magnet 132 can be placed at any position on the frame 10, the temple 11 and the hinge 12 of the smart glasses. The selection can be made according to the type of smart glasses and the peripherals.

[0041] Similarly, the detection module 13 can also be a detection device such as a mechanical micro switch, an infrared sensor, a time-of-flight sensor, etc. that can detect the opening and closing status of the temples.

[0042] In one embodiment, the sensing module is a sensor, which can be at least one of a capacitive sensor, a pressure sensor, and an infrared sensor. The capacitive sensor can be placed in a portion of the smart glasses that can come into contact with the human body when the glasses are normally worn. The capacitance value sensed by the capacitive sensor will change depending on whether the glasses are in contact with the human body. Specifically, when the user wears the smart glasses, the capacitive sensor comes into contact with the human body, and the capacitance value sensed by the capacitive sensor increases due to the effect of the human body. When the user takes off the smart glasses, i.e., when the user is not wearing the smart glasses, the capacitive sensor is not in contact with the human body, and the capacitance value sensed by the capacitive sensor will be smaller than the capacitance value when in contact with the human body. A capacitance threshold can be pre-set, and the capacitance value measured by the capacitive sensor is compared with the capacitance threshold to determine whether the smart glasses are being worn.

[0043] The voltage sensed by the pressure sensor changes depending on whether the smart glasses are being worn. When the user is wearing the smart glasses, the voltage sensed by the pressure sensor decreases. When the user takes off the smart glasses, the voltage sensed by the pressure sensor increases. Similarly, a voltage threshold can be pre-set and the voltage value measured by the pressure sensor compared to the threshold to determine whether the smart glasses are being worn.

[0044] The time it takes for the infrared sensor to sense infrared light varies depending on whether the smart glasses are being worn. When the user is wearing the smart glasses, the infrared sensor senses infrared light for a shorter time. When the user takes off the smart glasses, the infrared sensor senses infrared light for a longer time. Similarly, a time threshold can be pre-set and the time it takes for the infrared sensor to sense infrared light can be compared with the time threshold to determine whether the smart glasses are being worn.

[0045] In addition, the sensor can also be a distance sensor, such as a capacitive distance sensor, a time of flight (TOF) sensor, an infrared distance sensor, etc., and the distance sensor is used to generate a distance signal when the smart glasses are in a wearing state. Among them, the infrared distance sensor is used to generate an infrared signal when the smart glasses are in a wearing state. The TOF sensor can calculate the distance from the time of flight sensor to the user by sending a short pulse of light and measuring the return time through the direct time of flight (dToF) method, and determine whether the smart glasses are in a wearing state by judging the distance. The capacitive distance sensor is an existing commercially available product, and its use process will not be repeated here. By using a distance sensor, the human body can be sensed more accurately, the distance between the human body and the sensor / smart glasses can be accurately measured, and a distance signal can be generated when the smart glasses are in a wearing state.

[0046] In one embodiment, the smart glasses include a step-down module, and the control module is connected to the battery power module through the step-down module. In the present disclosure, the step-down module can be a low dropout regulator (LDO), and the input pin of the low dropout regulator is connected to the battery power module, and the output pin is connected to the control module. The low dropout regulator is used to step down the voltage output by the battery power module and input it into the control module to ensure the operation of the control module.

[0047] The smart glasses disclosed in the present invention can automatically turn on and off the smart glasses by detecting the opening and closing status of the temples through a detection module, without the need for the user to manually turn them on and off, thereby optimizing the user's usage operations, effectively reducing unnecessary energy consumption of the smart glasses, extending the usage time of the smart glasses, and enhancing the user experience.
