[0001] This application relates to the field of smart wearable device technology, and in particular to a smart wearable device. Background Technology

[0002] To protect the privacy of others in public places, smart wearable devices, such as smart glasses, smartwatches, and smart bracelets, typically have a corresponding camera indicator light that illuminates when the camera is activated, alerting others in public that the device is in recording mode. However, in reality, some users deliberately cover the light source of the camera indicator light on their smart wearable devices, preventing others in public from knowing whether the device is currently in use.

[0006] An infrared light receiving component is disposed within the housing;

[0007] The infrared light receiving component is used to detect the optical signal parameters of the infrared light signal illuminating itself, and output a corresponding optical signal parameter detection signal; and,

[0008] The control module is used to determine the occlusion state of the light output port based on the detection signal of the optical signal parameters.

[0009] Optionally, the infrared light emitting component includes an infrared light emitting component for emitting infrared light signals;

[0010] The infrared light receiving component includes an infrared light receiving component; the infrared light receiving component is used to detect the radiation value of the infrared light signal irradiating itself and output a corresponding infrared radiation detection signal.

[0011] The optical signal parameter detection signal includes the infrared radiation detection signal.

[0012] Optionally, the control module is configured to determine that the light outlet is in a blocked state when the difference between the radiation value of the infrared light signal illuminating the infrared light receiving component and a preset radiation value is greater than a preset difference, based on the infrared radiation detection signal.

[0013] Optionally, the infrared light emitting component is used to emit infrared light signals at a preset frequency;

[0014] The infrared light receiving component is used to filter the light signal illuminating itself at a preset frequency in order to detect the radiation value of the infrared light signal illuminating itself and output the corresponding infrared radiation detection signal.

[0015] Optionally, the smart wearable device further includes a camera module;

[0016] The control module is also configured to control the camera module to stop working when the light outlet is blocked; and to control the camera module to maintain its current state when the light outlet is not blocked.

[0017] Optionally, a transparent lens is provided inside the light outlet.

[0018] Optionally, an anti-sticking structure is provided on the housing corresponding to the position of the light outlet.

[0019] Optionally, the smart wearable device further includes: a substrate and a light-shielding structure disposed on the substrate, wherein the light-emitting component, the infrared light emitting component and the infrared light receiving component are disposed on the substrate;

[0020] The light-shielding structure, the substrate, and the inner side of the housing together form a first accommodating cavity, and the light-emitting component, the infrared light emitting component, and the infrared light receiving component are disposed within the accommodating cavity.

[0021] Optionally, a light guide is provided inside the housing corresponding to the light-emitting component, and the light guide is used to guide the light signal emitted by the light-emitting component to the outside of the light outlet.

[0022] Optionally, the smart wearable device further includes: a substrate and a light-shielding structure disposed on the substrate, wherein the infrared light emitting component and the infrared light receiving component are disposed on the substrate;

[0023] The light-shielding structure and the substrate together form a second accommodating cavity; the infrared light emitting component and the infrared light receiving component are disposed within the second accommodating cavity.

[0024] Optionally, the smart wearable device further includes a first light guide, which is disposed on the outside of the light-shielding structure and is used to guide the light signal emitted by the light-emitting component to the outside of the light outlet.

[0025] Optionally, the light outlet has a detection area and a light emission area, the first light guide is disposed in the light emission area, and the second accommodating cavity is disposed corresponding to the detection area;

[0026] The smart wearable device further includes at least one second light guide, which is disposed within the detection area and connected to the second light guide.

[0027] The smart wearable device of this application also includes an infrared light emitting component, an infrared light receiving component, and a control module. The infrared light emitting component is disposed within the housing and corresponds to the light emission port, and is used to emit infrared light signals. The infrared light receiving component is disposed within the housing and is used to detect the light signal parameters of the infrared light signal illuminating itself, and outputs a corresponding light signal parameter detection signal. The control module is used to determine the obstruction state of the light emission port based on the light signal parameter detection signal. Thus, in actual operation, when the light emission port corresponding to the light-emitting component serving as the shooting indicator is obstructed, a portion of the infrared light signal emitted by the infrared light emitting component that would normally exit through the light emission port will be reflected back into the housing by the obstruction and illuminate the infrared emitting component. The control module will determine whether the current light emission port is obstructed based on the light signal parameter detection signal output by the infrared light receiving component. With the above-mentioned settings in this application, the smart wearable device has the ability to detect whether the light outlet of the light-emitting component used to indicate the shooting status is blocked. This enables the camera module to be turned off in time when it is started and the light outlet is found to be blocked. This effectively improves the problem that users deliberately cover the shooting indicator light so that others in public places cannot know whether the smart wearable device worn by the user is working.

[0028] Simultaneously, obstruction detection is achieved through the cooperation of infrared emitting and receiving components. Since infrared light is invisible, it will not affect other users in public places, nor will it affect the normal operation of the light-emitting component that serves as the shooting indicator. Furthermore, because the infrared emitting component emits infrared light signals of a specific wavelength and the infrared receiving component only receives infrared light signals, it has strong anti-interference capabilities, thus effectively ensuring the accuracy of obstruction detection of the light outlet.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0043] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0045] To protect the privacy of others in public places, smart wearable devices, such as smart glasses, smartwatches, and smart bracelets, typically have a corresponding camera indicator light that illuminates when the camera is activated, alerting others in public that the device is in recording mode. However, in reality, some users deliberately cover the light source of the camera indicator light on their smart wearable devices, preventing others in public from knowing whether the device is currently in use.

[0046] It's important to understand that wearable devices differ from traditional smart terminals, such as smart glasses and smartphones. With smartphones, if a user wants to take photos in public, they must point the camera at the target, making it easy for the target to notice and realize they are being photographed. However, with smart glasses, it's normal for a user to look at someone while wearing them in public, for example, on the subway. If the user activates the camera to take a picture, the person being photographed will be unaware that they are being filmed. Therefore, wearable devices often have a camera indicator light that illuminates when the device is in camera mode to alert others in public. Currently, some users intentionally cover the light source of this indicator light, preventing others from knowing whether the device is in camera mode.

[0047] Therefore, this application proposes a smart wearable device, which includes a housing with a light-emitting port 60. A light-emitting component 10 is disposed inside the housing corresponding to the light-emitting port 60. The light-emitting component 10 can be composed of at least one light-emitting device such as an LED, fluorescent lamp, or incandescent lamp. When the shooting module in the smart wearable device is activated, for example, when the camera is activated, the light-emitting component 10 is controlled by the control module 30 or other control devices within the smart device to illuminate, so that it emits light through the light-emitting port 60, thereby notifying other people in public places that the smart device is currently in shooting mode.

[0048] refer to Figure 1 and Figure 4 In one embodiment of this application, the smart wearable device includes:

[0049] An infrared light emitting component 40 is disposed inside the housing and is positioned corresponding to the light outlet 60; the infrared light emitting component 40 is used to emit infrared light signals.

[0050] An infrared light receiving component 20 is disposed inside the housing;

[0051] The infrared light receiving component 20 is used to detect the optical signal parameters of the infrared light signal illuminating itself, and output a corresponding optical signal parameter detection signal; and,

[0052] The control module 30 is used to determine the occlusion state of the light output port 60 based on the detection signal of the optical signal parameters.

[0053] In this embodiment, the infrared light emitting component 40 can optionally be composed of an infrared LED and its peripheral power driving circuit, such as an infrared LED plus a constant current driving circuit; alternatively, the infrared light emitting component can also be directly implemented using an infrared light emitting module.

[0054] Optionally, the infrared light receiving component 20 can be implemented using an infrared receiving tube, such as an infrared receiving diode or an infrared receiving transistor, and its corresponding peripheral circuits, such as circuits for amplification, filtering, demodulation, and analog-to-digital conversion. Alternatively, the infrared light receiving component 20 can also be implemented using an infrared light receiving module. The infrared receiving component can detect the optical signal parameters of the infrared light signal illuminating it, such as radiation and infrared light intensity, and output the corresponding detection results.

[0055] Optionally, the control module 30 can be implemented using a main controller, such as an MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), PLC, or SOC (System On Chip).

[0056] As described above, during the actual operation of the smart wearable device, when the light-emitting component 10 is lit, the light signal emitted by it is emitted outward from the light-emitting port 60. Simultaneously, a portion of the infrared light signal emitted by the infrared light emitting component 40 is emitted outward from the light-emitting port 60, while another portion is reflected back into the housing through the inner wall of the housing and the inner and outer sides of the transparent lens 70 described in the following embodiments, illuminating the infrared light receiving component 20 inside the housing. It is understood that if the user blocks the light-emitting port 60 with their hand or an obstruction, the portion of the infrared light signal emitted by the infrared light emitting component 40 that is emitted through the light-emitting port 60 will be reflected back into the housing due to the obstruction and illuminate the infrared light receiving component 20 inside the housing. Compared to the unobstructed state, the parameters of the light signal detected by the infrared light receiving component 20 will change, such as changes in radiation and infrared light intensity. Therefore, the control module 30 can determine the current obstruction state of the light-emitting port 60 based on the light signal parameter detection signal output by the infrared light receiving component 20. For example, the control module 30 detects the optical signal parameters based on the signal, determines the amount of change in the optical signal parameters, and then determines whether the current output port 60 is blocked based on the amount of change; alternatively, the control module 30 determines whether the current output port 60 is blocked based on whether the optical signal parameters reach a preset threshold. For instance, since more infrared light signals are reflected to the infrared light receiving component 20 when the port is blocked compared to when it is not blocked, the control module 30 can determine that the current output port 60 is blocked when the amount of change in the optical signal parameters reaches a preset amount of change.

[0057] Optionally, in one embodiment, when the control module 30 determines that the current light outlet 60 is blocked, it can output the corresponding detection result to other control units in the smart wearable device, such as the control unit controlling the camera module 50. If the current detection result indicates that the current light outlet 60 is blocked and the camera module 50 is in operation, the control unit will control the camera module 50 to stop working, and can also remind the user not to accidentally block the light outlet 60 while recording.

[0058] Alternatively, in another embodiment, reference is made to... Figure 3 The smart wearable device also includes a camera module 5050; the camera module 5050 is electrically connected to the control module 30; the control module 30 is further configured to control the camera module 5050 to stop working when the light outlet 60 is blocked; and to control the camera module 5050 to maintain its current state when the light outlet 60 is not blocked. In this embodiment, the control module 30 can also directly control the working state of the camera module 5050. If it is determined that the light outlet 60 is not blocked, the camera module 5050 will maintain its current working state; if it is determined that the light outlet 60 is blocked, the camera module 5050 will be directly controlled to stop working.

[0059] Optionally, refer to Figure 2 The infrared light emitting component 40 can be controlled by the control module 30 or by other control units within the smart wearable device. Optionally, the infrared light emitting component 40 can start emitting infrared light signals when the smart wearable device is powered on, or it can start emitting infrared light signals when the camera module 50 is activated, i.e., when the light-emitting component 10 used for shooting indication is lit, in order to reduce the power consumption of the smart wearable device.

[0060] In summary, the smart wearable device of this application also includes an infrared light emitting component 40, an infrared light receiving component 20, and a control module 30. The infrared light emitting component 40 is disposed within the housing and corresponds to the light emission port 60, and is used to emit infrared light signals. The infrared light receiving component 20 is disposed within the housing and is used to detect the light signal parameters of the infrared light signal illuminating itself, and outputs a corresponding light signal parameter detection signal. The control module 30 is used to determine the occlusion state of the light emission port 60 based on the light signal parameter detection signal. Thus, in actual operation, when the light emission port 60 corresponding to the light-emitting component 10, which serves as the shooting indicator, is blocked, a portion of the infrared light signal emitted by the infrared light emitting component 40 that was originally emitted through the light emission port 60 will be reflected back into the housing by the obstruction and illuminate the infrared emitting component. The control module 30 will determine whether the current light emission port 60 is blocked based on the light signal parameter detection signal output by the infrared light receiving component 20. With the above-mentioned settings in this application, the smart wearable device has the ability to detect whether the light outlet 60 of the light-emitting component 10 used to indicate the shooting status is blocked. This enables the camera module 50 to be turned off in time when it is started and the light outlet 60 is found to be blocked. This effectively improves the problem that users deliberately cover the shooting indicator light so that others in public places cannot know whether the smart wearable device currently worn by the user is working.

[0061] Simultaneously, obstruction detection is achieved through the cooperation of infrared emitting and receiving components. Since infrared light is invisible, it will not affect other users in public places, nor will it affect the normal operation of the light-emitting component 10, which serves as the shooting indicator. Furthermore, because the infrared emitting component emits infrared light signals of a specific wavelength and the infrared receiving component only receives infrared light signals, it has strong anti-interference capabilities, thus effectively ensuring the accuracy of obstruction detection of the light outlet 60.

[0062] Optionally, in one embodiment of this application, the infrared light receiving component 20 is used to detect the radiation value of the infrared light signal irradiating itself and output a corresponding infrared radiation detection signal; wherein, the light signal parameter detection signal includes the infrared radiation detection signal.

[0063] In this embodiment, optionally, in one embodiment, the control module 30 can determine the rate of change of the radiation of the infrared light signal currently illuminating the infrared light receiving component 20 based on the infrared radiation detection signal. If the current rate of change suddenly exceeds the preset rate of change (obtained and preset by the R&D personnel through multiple tests during the R&D period), it indicates that the current user has suddenly blocked the light outlet 60, so that the infrared light signal emitted by the infrared light emitting component 40 through the light outlet 60 is reflected by the obstruction and then irradiates the infrared light receiving component 20, causing the rate of change of radiation to suddenly exceed the preset rate of change. At this time, the control module 30 can determine that the light outlet 60 is blocked.

[0064] Optionally, in another embodiment, the control module 30 is configured to determine that the light outlet 60 is in a blocked state when the difference between the radiation value of the infrared light signal illuminating the infrared light receiving component 20 and a preset radiation value is greater than a preset difference, based on the infrared radiation detection signal.

[0065] In this embodiment, researchers can conduct multiple tests during the research and development process to obtain the radiation value detection results output by the infrared light receiving component 20 under unobstructed conditions, and set the required preset radiation value as needed. This preset radiation value represents the theoretical value of the radiation value detection result output by the infrared receiving component under unobstructed conditions. If the light output port 60 is blocked, the radiation value detected and output by the infrared receiving component will be greater than the preset radiation value, or even much greater.

[0066] Therefore, if the control module 30 determines, based on the infrared radiation detection signal, that the difference between the radiation value of the infrared light signal illuminating the infrared light receiving component 20 and the preset radiation value is less than or greater than the preset difference, it indicates that the currently detected radiation value is close to the preset radiation value and is within the normal error range. In this case, the control module 30 will determine that the current light outlet 60 is not blocked.

[0067] If the control module 30 determines, based on the infrared radiation detection signal, that the difference between the radiation value of the infrared light signal illuminating the infrared light receiving component 20 and a preset radiation value is greater than a preset difference, it indicates that the difference between the currently detected radiation value and the preset radiation value is large. Therefore, the control module 30 can determine that the current light output port 60 is blocked. The preset difference can be determined by the R&D personnel based on the aforementioned measurement results.

[0068] With the above settings, the smart wearable device can detect the obstruction status of the light outlet 60 through the infrared light emitting component 40 and the infrared light receiving component 20. Furthermore, if the user obstructs the light outlet before the smart wearable device or the infrared light emitting component 40 is activated, a comparison with a preset radiation value can still be used to determine whether the light outlet 60 is blocked, thus further improving the accuracy of the detection of the obstruction status of the light outlet 60.

[0069] It is important to understand that during the detection of the occlusion status of the light output port 60, if the light output port 60 is not blocked, ambient light from the environment where the smart wearable device is located will also shine through the light output port 60. The ambient light may include infrared light signals of the same wavelength, which will affect the output results of the infrared receiving component and may easily lead to misjudgment of the occlusion status of the light output port 60 by the control module 30.

[0070] Therefore, in one embodiment of this application, the infrared light emitting component 40 is used to emit infrared light signals of a preset frequency;

[0071] The infrared light receiving component 20 is used to filter the light signal irradiated on itself according to a preset frequency, so as to detect the radiation value of the infrared light signal irradiated on itself and output the corresponding infrared radiation detection signal.

[0072] In this embodiment, optionally, the infrared light emitting component 40 may have the capability to output infrared light signals at a preset frequency. For example, if the user selects an infrared emitting component that outputs infrared light signals in pulses, it will output infrared light signals in 38kHz pulses. Optionally, the control module 30 or its control unit for controlling the infrared light emitting component 40 may control the infrared emitting component to operate at a preset frequency, either pre-stored or manually set, so that it outputs infrared light signals at the preset frequency.

[0073] The infrared receiving component has filtering capabilities. It filters the light signal incident on itself according to a preset frequency to receive only infrared light signals of the preset frequency, that is, only the infrared light signal emitted by the infrared light emitting component 40, and outputs the corresponding infrared radiation detection signal. This setting can effectively reduce the influence of the infrared portion of ambient light on the detection of the infrared receiving component, thereby effectively improving the accuracy of the control module 30 in judging the occlusion state of the light outlet 60.

[0074] Based on any of the above embodiments, optionally, in one embodiment, reference is made to Figures 4-9 In order to improve the uniformity of light output of the light-emitting component 10 and protect the light-emitting component 10 inside the housing, a transparent lens 70 is also provided inside the light outlet 60.

[0075] Based on any of the above embodiments, optionally, in one embodiment, reference is made to Figure 5 In one embodiment of this application, a light guide 110 is provided inside the housing corresponding to the light-emitting component 10. The light guide 110 is used to guide the light signal emitted by the light-emitting component 10 to the outside of the light outlet 60. In this embodiment, to improve the effect of the light signal emitted by the light-emitting component 10 exiting the light outlet 60, a light guide 110 can also be provided at a position corresponding to the light-emitting component 10. The light guide 110 can be implemented using a light guide post, such as a silicone light guide post or a plastic light guide post, and the light guide 110 can also be filled with light-diffusing powder. Through the above settings, the light emission effect of the light-emitting component 10 can be effectively improved, enhancing the warning effect to passersby.

[0076] Based on any of the above embodiments, optionally, in one embodiment, reference is made to Figure 7 An anti-stick structure 160 is provided on the housing corresponding to the position of the light outlet 60. In this embodiment, in order to reduce the possibility of users blocking the light outlet 60 by sticking objects on it, an anti-stick structure 160 can also be provided on the light outlet 60. For example, multiple protrusions are provided on the periphery of the light outlet 60, and the multiple protrusions can be of different heights to make it difficult for obstructions to stick on the light outlet 60. Alternatively, when a transparent lens 70 is provided on the light outlet 60, an anti-stick structure 160, such as protrusions and anti-slip textures, can be provided on the end face of the transparent lens 70 facing outward from the housing to make it difficult for obstructions to stick on the light outlet 60.

[0077] Based on any of the above embodiments, in order to reduce the detection interference of other light-emitting units, especially those emitting infrared light, to the infrared receiving component within the smart wearable device, optionally, in one embodiment, referencing Figure 4 The smart wearable device further includes: a substrate 100 and a light-shielding structure 80 disposed on the substrate 100, wherein the light-emitting component 10, the infrared light emitting component 40 and the infrared light receiving component 20 are disposed on the substrate 100.

[0078] The light-shielding structure 80, the substrate 100, and the inner side of the housing together form a first accommodating cavity 90, and the light-emitting component 10, the infrared light emitting component 40, and the infrared light receiving component 20 are disposed in the accommodating cavity.

[0079] In this embodiment, the substrate 100 can be implemented using a fiberglass circuit board, a flexible circuit board, a ceramic substrate 100, etc., and the light-shielding structure 80 can be implemented using plastic parts, metal parts, etc., so that the light signals emitted by other modules in the smart wearable device, especially the infrared light signals, will not illuminate the infrared light receiving component 20 in the accommodating cavity, so as to ensure the detection sensitivity of the infrared light receiving component 20, and also so that the part of the light signal emitted by the light-emitting component 10 reflected back into the housing will not be reflected outside the first accommodating cavity 90.

[0080] Based on any of the above embodiments, in order to reduce the detection interference of other light-emitting units, especially those emitting infrared light, to the infrared receiving component within the smart wearable device, alternatively, in another embodiment, refer to... Figure 6 The smart wearable device further includes: a substrate 100 and a light-shielding structure 80 disposed on the substrate 100, wherein the infrared light emitting component 40 and the infrared light receiving component 20 are disposed on the substrate 100.

[0081] The light-shielding structure 80 and the substrate 100 together form a second accommodating cavity 130; the infrared light emitting component 40 and the infrared light receiving component 20 are disposed within the second accommodating cavity 130.

[0082] In this embodiment, the substrate 100 and the light-shielding structure 80 can be implemented in the manner described in the above embodiments. The second accommodating cavity 130 only houses the external light emitting component and the infrared light receiving component 20, thereby more effectively reducing the impact of light signals emitted by other modules within the smart wearable device, particularly infrared light signals, on the infrared receiving component, and reducing the impact of any infrared portion in the light signal emitted by the light-emitting component 10 on the infrared receiving component. Simultaneously, the light-emitting component 10 is positioned corresponding to the light-emitting port 60 and located outside the second accommodating cavity 130, which reduces the light-emitting area of ​​the light-emitting port 60, thereby reducing glare.

[0083] Furthermore, in order to improve the uniformity of light output, refer to Figure 7 The smart wearable device further includes a first light guide 120, which is disposed on the outside of the light-shielding structure 80. The first light guide 120 is used to guide the light signal emitted by the light-emitting component 10 to the outside of the light outlet 60. In this embodiment, the first light guide 120 can be implemented using the same embodiment as the light guide 110 described above. Viewed from the outside of the light outlet 60, the first light guide 120 can be of various shapes, such as square, rectangular, curved, etc. Figure 8 The circular shape effectively improves the uniformity of light emitted by the light-emitting component 10.

[0084] It should be understood that, based on the above embodiments, the light-emitting component 10 is disposed outside the second accommodating cavity 130. Therefore, the light-emitting port 60 is actually divided into a light-emitting area 140 and a detection area 150. The detection area 150 is the region of the light-emitting port corresponding to the second accommodating cavity 130, and the light-emitting area 140 is the region where the light-emitting component 10 emits light. The first light guide 120 is also disposed within the light-emitting area 140 to guide the light signal emitted by the light-emitting component 10. In practice, since the light-emitting area 140 and the detection area 150 are independent of each other, if the user only covers the light-emitting area 140 with an obstruction and does not cover the detection area 150, the control module 30 may determine that the current light-emitting port 60 is not blocked.

[0085] Therefore, in one embodiment of this application, reference is made to Figure 9 The smart wearable device further includes at least one second light guide 170, which is disposed within the detection area 150 and connected to each other. The second light guide 170 can adopt the same embodiment as the first light guide 120 and light guide 110 described above. The second light guide 170 can be of any shape. For example, refer to... Figure 9 , Figure 9 Viewed from outside the light outlet 60, the first light guide 120 is circular in shape. The first light guide 120 can span the detection area 150, and its two ends are connected to the first light guide 120 in the light outlet area 140. With this configuration, if the user intentionally only blocks the first light guide 120 within the light outlet area 140, the detection area 150 will also be blocked simultaneously. This allows the control module 30 to recognize that the light outlet 60 is currently blocked, effectively improving the accuracy of the smart wearable device's detection of the light outlet 60.
