[0002] In modern society, with the increasing awareness of personal privacy protection, the demand for privacy protection in various places is becoming increasingly prominent. This is especially true in places with high confidentiality requirements, such as office buildings and hotels, where privacy protection issues are receiving more and more attention. For example, in office buildings: when users are processing confidential documents or conducting business meetings, it is necessary to prevent confidential information from being stolen by outsiders. In hotel rooms: when users are carrying out their daily activities inside the room, it is necessary to prevent them from being spied on or photographed by outsiders.
[0003] Currently, indoor spaces typically use curtains, blinds, and other light-blocking devices to block outside views and prevent peeping or upskirting. However, when using these devices for privacy protection, users need to manually pull them down, which is inconvenient. Utility Model Content

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0040] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms.

For example, if a device in the figures is flipped, an element or feature described as "below" or "under" or "below" other elements or features will be oriented "above" other elements or features.

Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.
[0043] In one exemplary embodiment, such as Figure 1As shown, an application environment for an electrochromic control device 100 is provided. The electrochromic control device 100 can be electrically connected to an electrochromic glass module 200 inside a preset space 10. When the electrochromic control device 100 detects the presence of a privacy-protected object 11 inside the preset space 10 and triggers a preset privacy-protected color-changing logic, it outputs a corresponding voltage to the electrochromic glass module 200, causing the electrochromic glass module 200 to change from an initial transparent state to a transparent state to a non-transparent state. This satisfies the privacy protection requirements of the privacy-protected object 11 inside the preset space 10, improving the control intelligence and flexibility of the electrochromic glass module 200. When the electrochromic control device 100 does not detect the presence of a privacy protection object 11 inside the preset space 10, or when the preset state initialization color-changing logic is triggered, it changes the voltage output to the electrochromic glass module 200 to control the electrochromic glass module 200 to initialize from a transparent state to a transparent state, thereby achieving automatic restoration of the electrochromic glass module 200, reducing the energy consumption and cost of controlling the electrochromic glass module when there is no privacy protection requirement, and improving the light transmittance inside the preset space 10.
[0044] In one exemplary embodiment, such as Figure 2 As shown, a structural block diagram of an electrochromic control device 100 is also provided, including an environmental sensor 102, a distance sensor 104, a processor 106, and a power control module 108.
[0045] The environmental sensor 102 can be a sensor used to detect gas composition parameters in the air. Optionally, in some embodiments, the environmental sensor 102 can be configured to be triggered and send corresponding environmental trigger information when it detects that environmental parameters inside the preset space 10 match target environmental parameters. The target environmental parameters can be environmental parameters collected by the environmental sensor 102 when a privacy-protected object 11 is present inside the preset space 10. The environmental parameters can be used to characterize the gas composition parameters in the air inside the preset space 10. The environmental trigger information can be used to characterize information that determines the presence of a privacy-protected object 11 inside the current preset space 10 based on the environmental parameters. The privacy-protected object 11 can be used to characterize a user who requires privacy protection inside the preset space 10.
[0046] The distance sensor 104 can characterize a sensor used for detecting distance. Optionally, in some embodiments, the distance sensor 104 can be configured to be triggered and send a corresponding status value when the privacy-protected object 11 is detected within a preset operating range. The status value can be used to characterize that the distance sensor 104 is triggered by the privacy-protected object 11.
[0047] The processor 106 includes multiple input terminals, which can be electrically connected to the environmental sensor 102 and the distance sensor 104 respectively through different input terminals. The output terminal of the processor 106 can be connected to the input terminal of the power control module 108. The processor 106 may be equipped with a control chip that stores preset electrochromic glass module control logic. The control chip performs corresponding data logic processing on the received data information to realize the corresponding electrochromic glass module control operation. Optionally, in some embodiments, the processor 106 can be configured to detect the trigger status of the distance sensor 104 within a preset time period when it receives environmental trigger information sent by the environmental sensor 102, and generate a corresponding control command based on the received status value, and send the control command to the power control module 108.
[0048] The power control module 108 can characterize a power supply device for providing the voltage required for the electrochromic glass module 200 to change color. The power control module 108 can be configured to adjust the voltage output to the electrochromic glass module 200 according to the control instructions of the processor 106, so as to change the transparent state of the electrochromic glass module 200.
[0049] For example, when a user enters a preset space 10 such as an office building or hotel, the gas composition parameters in the air inside the preset space 10 will inevitably change. Therefore, the electrochromic control device 100 can detect the environmental parameters inside the preset space 10 through the environmental sensor 102, and compare the value of the currently detected environmental parameter with the value of the target environmental parameter to determine whether a privacy-protected object 11 has entered the preset space 10. When the environmental parameter is greater than or equal to the target environmental parameter, the environmental sensor 102 is triggered, and sends the corresponding environmental trigger information indicating the presence of a privacy-protected object 11 inside the preset space 10 to the processor 106 of the electrochromic control device 100.
[0050] The electrochromic control device 100 can scan within a preset working range using a distance sensor 104 in a non-contact manner (such as infrared signals, radar signals, capacitance changes, microwave reflections, etc.). When the privacy-protected object 11 enters the preset working range of the distance sensor 104, it triggers the distance sensor 104 to send a corresponding status value to the processor 106, indicating to the processor 106 that the distance sensor 104 has been triggered by the privacy-protected object 11.
[0051] The electrochromic control device 100 can detect the triggering state of the distance sensor 104 within a preset time period by reading the status value sent by the distance sensor 104 within a preset time period after receiving environmental trigger information sent by the environmental sensor 102 via the processor 106.
[0052] For example, in some implementations, if multiple status values are received within a preset time period, the processor 106 can determine that the distance sensor 104 has been triggered multiple times within the preset time period. In this case, a preset privacy-preserving color-changing logic is executed to generate a corresponding control command, which is then sent to the power control module 108. The power control module 108 can adjust the voltage output to the electrochromic glass module 200 according to the control command based on the privacy-preserving color-changing logic, thereby changing the transparent state of the electrochromic glass module 200 to non-transparent.
[0053] Alternatively, in some other embodiments, if only one status value is received within a preset time period, the processor 106 can determine that the distance sensor 104 has been accidentally touched or interfered with within that time period. In this case, a preset state initialization color-changing logic is executed to generate a corresponding control command, which is then sent to the power control module 108. The power control module 108 can adjust the power output to the electrochromic glass module 200 according to the control command generated based on the state initialization color-changing logic, thereby changing the transparent state of the electrochromic glass module 200 to transparent.
[0054] The aforementioned electrochromic control device 100, by utilizing the processor 106 in conjunction with the environmental trigger information of the environmental sensor 102 and the state value of the distance sensor 104 within a preset time period, generates control commands for changing the transparent state of the electrochromic glass module 200. This not only enables intelligent and automated control of the electrochromic glass module 200, but also improves the accuracy of electrochromic control.
[0055] Optionally, in some implementations, environmental parameters may include, but are not limited to, carbon dioxide concentration or human body volatile organic compound concentration. In this embodiment, environmental parameters such as carbon dioxide concentration or human body volatile organic compound concentration are detected by environmental sensor 102. When the environmental parameters match the target environmental parameters, an environmental triggering information is sent indicating the presence of a privacy-protected object within the currently preset space, thereby improving the reliability and accuracy of the environmental triggering information.
[0056] Optionally, in other embodiments, the distance sensor 104 may include, but is not limited to, at least one of a second infrared sensor, a proximity sensor, or a ratiometric absorptivity sensor (RAS). In this embodiment, by using at least one of a non-contact sensor such as a second infrared sensor, a proximity sensor, or a ratiometric absorptivity sensor as the distance sensor, the range of distance detection and the trigger response speed of the distance sensor can be expanded.
[0057] In one exemplary embodiment, such as Figure 3As shown, a schematic diagram of a distance sensor 104 is also provided, including a first sensing unit 1042 and a second sensing unit 1044. The first sensing unit 1042 and the second sensing unit 1044 can be deployed in different areas of the electrochromic glass module 200. The first sensing unit 1042 and the second sensing unit 1044 are each electrically connected to an output terminal of the processor 106.
[0058] The first sensing unit 1042 can be configured to be triggered when a privacy-protected object 11 is detected within a first working range of its deployment, and to generate a corresponding first state value.
[0059] The second sensing unit 1044 can be configured to be triggered and generate a corresponding second state value when a privacy-protected object 11 is detected within a second working range of its deployment.
[0060] For example, the processor 106 may also be configured to, when both the first sensing unit 1042 and the second sensing unit 1044 are detected to be triggered within a preset time period, determine a target state value from the first state value and the second state value according to the triggering order of the first sensing unit 1042 and the second sensing unit 1044, and generate a control command corresponding to the target state value; or, when neither the first sensing unit 1042 nor the second sensing unit 1044 is detected to be triggered within the preset time period, use a preset third state value as the target state value to generate a corresponding control command.
[0061] For example, the electrochromic control device 100 can also receive status values sent by the first sensing unit 1042 and the second sensing unit 1044 via the processor 106. If the first and second status values are received within a preset time period, the processor 106 can determine the triggering order of the first sensing unit 1042 and the second sensing unit 1044 based on the sending / receiving time of the first and second status values, and determine the target status value from the first and second status values according to the triggering order. For example, if the first sensing unit 1042 triggers first, the first status value is used as the target status value. Alternatively, if the second sensing unit 1044 triggers first, the second status value is used as the target status value. If no status value is received within the preset time period, or only one of the first and second status values is received, a preset third status value can be used as the target status value to generate a corresponding control command.
[0062] Optionally, in some implementations, when the target state value is the first state value, the processor 106 can generate a control command for controlling the transparent state of the electrochromic glass module 200 to change to transparent based on the target state value.
[0063] In other embodiments, when the target state value is the second state value, the processor 106 can generate a control command to control the transparent state of the electrochromic glass module 200 to change to non-transparent based on the target state value.
[0064] Alternatively, in other implementations, when the target state value is the third state value, the processor 106 can generate control instructions for controlling the electrochromic glass module 200 to remain transparent based on the target state value.
[0065] In this embodiment, by setting multiple sensing units and determining the corresponding target state value according to the triggering order of different sensing units within a preset time period, the processor can generate different control instructions based on the target state value, thereby improving the flexibility of electrochromic glass module control and enriching the control functions of electrochromic glass module.
[0066] In one exemplary embodiment, the electrochromic control device 100 may further include a first infrared sensor, wherein the output of the first infrared sensor may be electrically connected to one of the inputs of the processor 106.
[0067] The first infrared sensor can be installed at the entrance of the preset space 10 to detect whether a user has entered the preset space 10. The first infrared sensor can be configured to be triggered and send corresponding infrared trigger information when it detects that infrared signal data inside the preset space 10 matches preset infrared data. The preset infrared data can be infrared signal data collected when a privacy-protected object 11 is present inside the preset space 10.
[0068] The processor 106 can also be configured to detect the triggering status of the distance sensor 104 within a preset time period when it receives infrared triggering information sent by the first infrared sensor.
[0069] For example, when a user enters the preset space 10, the first infrared sensor can be triggered to generate infrared trigger information indicating the presence of a privacy-protected object 11 within the preset space 10, and the infrared trigger information can be sent to the processor 106. Upon receiving at least one of the environmental trigger information or the infrared trigger information, the processor 106 can determine that a privacy-protected object 11 exists within the current preset space 10, and perform the operation of detecting the trigger status of the distance sensor 104 within a preset time period.
[0070] In this embodiment, by redundantly setting a first infrared sensor that performs the same function as the environmental sensor 102, the problem of the processor 106 making a judgment error when the environmental sensor 102 has a single point of failure or is interfered with can be avoided.
[0071] In one exemplary embodiment, the electrochromic control device 100 may further include a radar sensor, wherein the output of the radar sensor may be electrically connected to one of the inputs of the processor 106.
[0072] A radar sensor can be installed at the entrance of the preset space 10 to detect whether a user has entered the preset space 10. The radar sensor can be configured to be triggered and send corresponding radar trigger information when it detects that radar signal data inside the preset space 10 matches preset radar data. The preset radar data can be radar signal data collected when a privacy-protected object 11 is present inside the preset space 10.
[0073] The processor 106 can also be configured to detect the triggering status of the distance sensor 104 within a preset time period when receiving radar triggering information sent by the radar sensor.
[0074] For example, when a user enters the preset space 10, the radar sensor can be triggered to generate radar trigger information indicating the presence of a privacy-protected object 11 within the preset space 10, and the radar trigger information can be sent to the processor 106. Upon receiving at least one of the environmental trigger information or the radar trigger information, the processor 106 can determine that a privacy-protected object 11 exists within the current preset space 10, and perform the operation of detecting the trigger status of the distance sensor 104 within a preset time period.
[0075] In this embodiment, by redundantly setting up a radar sensor that performs the same function as the environmental sensor 102, the problem of the processor 106 making incorrect judgments when the environmental sensor 102 experiences a single point of failure or is interfered with can be avoided.
[0076] Optionally, in some embodiments, a first infrared sensor or a radar sensor may be used instead of the environmental sensor 102 to form the electrochromic control device 100. Alternatively, in other embodiments, the electrochromic control device 100 may also redundantly provide the first infrared sensor, the radar sensor, and the environmental sensor 102 to avoid single-point failure problems.
[0077] Alternatively, in other embodiments, depending on actual usage requirements, the same infrared sensing device can be used to perform both the function of the first infrared sensor in detecting whether a privacy-protected object 11 exists inside the current preset space 10 and the function of the second infrared sensor as a distance sensor, thereby improving the utilization rate of the sensing device and reducing the hardware cost of the electrochromic control device 100.
[0078] Alternatively, in some embodiments, a voltage control module may be used instead of the power control module 108 to form the electrochromic control device 100.
[0079] In one exemplary embodiment, such as Figure 4 As shown, a structural block diagram of an electrochromic control device 100 is also provided, including an environmental sensor 102, a first sensing unit 1042, a second sensing unit 1044, a processor 106, and a power control module 108.
[0080] For example, when a user enters the preset space 10, the environmental sensor 102 is triggered to send corresponding environmental trigger information to the processor 106. When the user enters the first working range of the first sensing unit 1042, the first sensing unit 1042 is triggered to send a first status value to the processor 106. When the user enters the second working range of the second sensing unit 1044, the second sensing unit 1044 is triggered to send a second status value to the processor 106. Optionally, in some embodiments, the first sensing unit 1042 and the second sensing unit 1044 can also be triggered by detecting the user's limb parts (such as hand position). The following example uses the detection of hand position as an illustration: Figure 5 As shown, when a user needs privacy protection, the user can wave their hand clockwise to trigger the second sensing unit 1044 and then the first sensing unit 1042, thereby controlling the electrochromic glass module 200 to change from a transparent state to a non-transparent state. When the user does not need privacy protection, the user can wave their hand counterclockwise to trigger the first sensing unit 1042 and then the second sensing unit 1044, thereby controlling the electrochromic glass module 200 to change from a transparent state to a transparent state. After the user leaves the preset space 10, the environmental sensor 102 is not triggered, and the processor 106 can send a control command to the power control module 108 after a preset time period to control the electrochromic glass module 200 to change from a transparent state to a transparent state. Those skilled in the art will understand that... Figure 5 The illustrated deployment method does not constitute a limitation on the deployment of the first sensing unit 1042 and the second sensing unit 1044 on the electrochromic glass module 200 of this utility model. Based on the technical concept of this utility model, the first sensing unit 1042 and the second sensing unit 1044 can also be deployed at different positions, such as diagonally opposite each other, in the electrochromic glass module 200 according to user needs.
[0081] Upon receiving environmental triggering information, the processor 106 can determine that a privacy-protected object 11 exists within the current preset space 10, and detect the triggering status of the first sensing unit 1042 and the second sensing unit 1044 within a preset time period.
[0082] If the processor 106 detects that the first sensing unit 1042 is triggered first and the second sensing unit 1044 is triggered subsequently within a preset time period, it can take the first state value (e.g., 1) sent by the first sensing unit 1042 as the target state value, generate a corresponding control command, and send the control command to the power control module 108. The power control module 108 can adjust the voltage output to the electrochromic glass module 200 according to the control command to change the transparent state of the electrochromic glass module 200 to non-transparent.
[0083] Alternatively, if the processor 106 detects that the second sensing unit 1044 is triggered first and the first sensing unit 1042 is triggered within a preset time period, it can use the second state value (e.g., 2) sent by the second sensing unit 1044 as the target state value, generate a corresponding control command, and send the control command to the power control module 108. The power control module 108 can adjust the voltage output to the electrochromic glass module 200 according to the control command to change the transparent state of the electrochromic glass module 200 to transparent.
[0084] Alternatively, if the processor 106 detects that only the first sensing unit 1042 or the second sensing unit 1044 is triggered within a preset time period, or if neither the first sensing unit 1042 nor the second sensing unit 1044 is triggered, it can use a preset third state value (such as 0) as the target state value, generate a corresponding control command, and send the control command to the power control module 108. The power control module 108 can adjust the voltage output to the electrochromic glass module 200 according to the control command to change the transparent state of the electrochromic glass module 200 to transparent.
[0085] In this embodiment, by combining the environmental triggering information from the environmental sensor with the state values and triggering sequence of the first and second sensing units within a preset time period, corresponding control commands are generated. This not only enables intelligent and automated control of the electrochromic glass module 200 when the user enters the preset space and triggers different sensing units in sequence, thus improving the color-changing flexibility of the electrochromic glass module 200 and meeting the user's privacy protection needs under different circumstances, but also maintains the transparent state of the electrochromic glass module 200 when the user is not in the preset space or when privacy protection is not required, thereby reducing the energy consumption and cost of controlling the electrochromic glass module and optimizing the lighting effect inside the preset space 10.
[0086] In one exemplary embodiment, such as Figure 6The diagram illustrates the connection between an electrochromic glass module 200 and an electrochromic control device 100. The electrochromic glass module 200 can be electrically connected to the electrochromic control device 100 via the power control module 108 described in the above embodiments. The electrochromic glass module 200 can be configured to change its transparency state based on the voltage output by the power control module 108. The voltage output by the power control module 108 can be generated according to control instructions generated by the processor 106 described in the above embodiments. The specific generation of these control instructions can be implemented using the control instruction generation methods provided in the above embodiments, and will not be elaborated further here.
[0087] Alternatively, in some implementations, such as Figure 7 As shown, a structural block diagram of an electrochromic glass module 200 is also provided, wherein the electrochromic glass module 200 may be, but is not limited to, composed of a transparent substrate 210, a transparent conductive layer 230, an electrochromic layer 250, an electrolyte layer 270, and an ion storage layer 290.
[0088] The transparent substrate 210 can be deployed on the outermost layer of the electrochromic glass module 200. Optionally, in some embodiments, the transparent substrate 210 can be made of a flexible material or a glass material with a Mohs hardness of 7 (i.e., 7H) based on user requirements. The transparent substrate 210 is mainly used to support the entire electrochromic glass module 200.
[0089] A transparent conductive layer 230 may be attached to the inner side of the transparent substrate 210. The transparent conductive layer 230 typically possesses good conductivity and transparency, allowing light to pass through while also enabling connection to external circuits. The transparent conductive layer 230 may include a positive conductive layer 231 and a negative conductive layer 233. The positive conductive layer 231 can be connected to the ion storage layer 290, and the negative conductive layer 233 can be connected to the electrochromic layer 250. The transparent conductive layer 230, through the positive conductive layer 231 and the negative conductive layer 233, provides a stable electron supply to the electrochromic layer 250 and the ion storage layer 290, respectively.
[0090] The electrochromic layer 250 is the most important functional layer in the electrochromic glass module 200. The change in transparency occurs in this layer, and its color change and color-changing speed can be influenced by numerical control technology. Electrochromism is a phenomenon in which the optical properties of a material (such as reflectivity, transmittance, and absorptivity) undergo stable and reversible color changes under the action of an external electric field. This manifests as reversible changes in color and transparency.
[0091] An electrolyte layer 270 (i.e., Electrolyte) can be deployed between the ion storage layer 290 and the electrochromic layer 250. The electrolyte layer 270 provides a channel for ion movement, allows light to pass through, and serves to provide color-changing ions and block electrons.
[0092] The ion storage layer 290 is the counter electrode of the electrochromic film, used to release ions and realize the color change of the electrochromic glass module 200.
[0093] Optionally, in some embodiments, the positive conductive layer 231 of the electrochromic glass module 200 can be connected to the positive output of the power control module 108, and the negative conductive layer 233 can be connected to the negative output of the power control module 108.
[0094] In one exemplary embodiment, an electrochromic window is also provided, which may include a window frame and the electrochromic glass module 200 of any of the above embodiments. The electrochromic window can be installed in a preset space 10 and changes its transparency state by receiving the voltage output by the electrochromic control device 100, thereby meeting the privacy protection needs of the privacy protection object 11 inside the preset space 10.
