Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment, and in particular to a testing device for detecting electrochromic devices. Background Technology
[0002] Electrochromic (EC) devices are a class of smart materials that reversibly alter their optical properties (such as transmittance and reflectance) under the influence of an applied electric field. They are widely used in energy-efficient buildings, automotive anti-glare rearview mirrors, and display devices. Their core mechanism lies in the ion insertion / extraction caused by electrochemical redox reactions, which in turn alter the material's band structure. The performance evaluation of these devices is highly dependent on the coordinated detection of photoelectric signals—the electrical signal (voltage / current) at a specific moment directly determines its coloring state (such as coloring depth and uniformity), and this state needs to be quantitatively verified through optical signals (such as transmission spectroscopy).
[0003] However, there is currently a lack of specialized testing equipment for this type of device. In particular, electrochromic devices vary greatly in size due to their different stages of development, product forms, and applicable scenarios, ranging from as small as 1cm*1cm to as large as 2m*2m. All of these require testing of their optical performance, which further increases the difficulty of testing.
[0004] Therefore, there is currently no good solution to this problem. Utility Model Content
[0005] In order to overcome the above-mentioned technical defects, the purpose of this utility model is to provide a testing device for detecting electrochromic devices.
[0006] This utility model discloses a testing device for detecting electrochromic devices, including at least one testing module; the at least one testing module includes an optical signal acquisition module and a light source arranged sequentially at intervals in a first direction, and a signal processing module;
[0007] The optical signal acquisition module is located on one side of the object to be detected and includes a fixing component and at least one sensor. The sensor is fixed to the fixing component and is used to acquire the optical performance of the electrochromic device.
[0008] The light source is positioned on the other side of the object to be detected, so that the light emitted by the light source passes through the object to be detected and is received by the sensor;
[0009] The signal processing module is electrically connected to the optical signal acquisition module to process the optical signals received by the sensor;
[0010] At least one test module also includes a base, which is disposed on one side of the optical signal acquisition module and the light source in the second direction and is fixedly connected to both the optical signal acquisition module and the light source. The second direction is perpendicular to the first direction.
[0011] Preferably, the fastener is composed of multiple fastener units, which are arranged sequentially along the second direction and the third direction, and any two adjacent fastener units are fixedly connected to each other so that the fastener extends along the first direction and the second direction; the third direction is perpendicular to both the first direction and the second direction.
[0012] The sensor is fixedly connected to the fixture unit.
[0013] Preferably, the fastener unit includes a first protrusion and a first receiving groove provided on both sides of the direction of the straight line in the second direction;
[0014] This allows the first protrusion of one fastener unit and the first receiving groove of another fastener unit to cooperate with each other, thereby achieving a fixed connection between the two fastener units in the second direction.
[0015] Preferably, the fastener unit includes a second protrusion and a second receiving groove provided on both sides in the direction of the third-party straight line;
[0016] This allows the second protrusion of one fastener unit and the second receiving groove of another fastener unit to cooperate with each other, thereby achieving a fixed connection between the two fastener units in the third direction.
[0017] Preferably, when at least one sensor includes multiple sensors:
[0018] Multiple sensors are evenly arranged on the surface of the fixture facing the object to be detected;
[0019] Alternatively, multiple sensors may be arranged in a ring around the inner periphery of the surface of the fixture facing the object to be detected.
[0020] Preferably, the light source consists of at least one light source module; when the at least one light source module includes multiple light source modules, the multiple light source modules are arranged sequentially and relatively fixed along the second direction and / or the third direction.
[0021] Preferably, the projection of the light source in the first direction covers more than 3 / 4 of the object to be detected.
[0022] Preferably, the testing equipment further includes an electrical signal acquisition module, which is electrically connected to the signal processing module.
[0023] Preferably, when the testing equipment includes multiple testing modules, the multiple testing modules are arranged sequentially along the second direction.
[0024] Compared with existing technologies, the above technical solution has the following advantages:
[0025] 1. This solution achieves optical path structural stability through modular layout and base support. Fixed connections between modules reduce relative displacement, ensuring light accurately passes through the object being measured and is received by the sensor; the base provides overall support, preventing equipment deformation during large-scale testing and guaranteeing measurement accuracy. Furthermore, this modular design allows for adaptation to large-scale objects through multiple modules, reducing testing and usage complexity.
[0026] 2. The fasteners are composed of modular units, supporting flexible expansion in a two-dimensional plane and overcoming limitations of fixed dimensions. The protrusions and receiving slots work together to achieve quick unit positioning and connection, while bidirectional locking ensures the rigidity of the spliced structure. The modular design of the light source allows the illumination area to match devices of different sizes, and multiple test modules can be expanded to meet the testing needs of various sizes.
[0027] 3. Offers dual sensor modes: uniform distribution and circular arrangement, suitable for full-area analysis or central area detection. The light source projection covers the main area of the object under test, eliminating measurement deviations caused by insufficient edge illumination;
[0028] 4. An integrated electrical signal acquisition module is directly connected to the processing module to accurately achieve synchronous acquisition of electrical parameters and optical signals. Attached Figure Description

[0044] Please see Figures 1-2 , Figure 1 A three-dimensional structural schematic diagram of the testing equipment for detecting electrochromic devices provided in this application;
[0045] Figure 2 This is a front view structural diagram of the test equipment for detecting electrochromic devices provided in this application.
[0046] like Figure 1 As shown, this utility model discloses a testing device for testing electrochromic devices (such as electrochromic glass), including at least one testing module 200; the at least one testing module 200 includes an optical signal acquisition module 1 and a light source 2 arranged sequentially at intervals in a first direction z, and a signal processing module 3;
[0047] The optical signal acquisition module 1 is disposed on one side of the object to be tested and includes a fixing member 11 and at least one sensor 12. The sensor 12 is fixed to the fixing member 11 and is used to acquire the optical performance of the electrochromic device. It should be noted that the specific data acquired by the optical signal acquisition module 1 is not limited. In one possible implementation, the optical signal acquisition module 1 acquires the transmittance of the device to be tested.
[0048] The light source 2 is positioned on the other side of the object to be detected, so that the light emitted by the light source 2 passes through the object to be detected and is received by the sensor 12;
[0049] The signal processing module 3 is electrically connected to the optical signal acquisition module 1 to process the optical signals received by the sensor 12;
[0050] At least one test module 200 also includes a base 4, which is disposed on one side of the optical signal acquisition module 1 and the light source 2 in the second direction x, and is fixedly connected to both the optical signal acquisition module 1 and the light source 2. The second direction x is perpendicular to the first direction z.
[0051] This solution achieves optical path structural stability through a modular layout and support from base 4. Fixed connections between modules reduce relative displacement, ensuring light accurately passes through the object being measured and is received by sensor 12. Base 4 provides overall support, preventing equipment deformation during large-scale testing and guaranteeing measurement accuracy. Furthermore, this modular design allows for adaptation to large-scale objects using multiple modules, reducing testing and usage complexity.
[0052] Those skilled in the art will understand that the specific location of the signal processing module 3 described herein is not limited. In one possible implementation, such as... Figure 1As shown, the signal processing module 3 can be disposed on one side of the base 4 in the first direction z and fixed to the base 4. In another possible implementation, the signal processing module 3 can also be disposed independently outside the test module 200. This application does not impose any limitations.
[0053] The above is an explanation of the basic concept of this application. The following will describe in detail the possible specific structures of each component of this application with reference to the accompanying drawings.
[0054] First, the specific structure of the fastener 11 is not limited.
[0055] In one possible implementation, the fastener 11 is composed of a plurality of fastener units 111, which are arranged sequentially along the second direction x and the third direction y, and any two adjacent fastener units 111 are fixedly connected to each other so that the fastener 11 extends along the first direction z and the second direction x; the third direction y is perpendicular to both the first direction z and the second direction x.
[0056] Sensor 12 is fixedly connected to fixture unit 111.
[0057] The fastener 11 is composed of modular units that support flexible expansion in the second direction x and the third direction y, thus solving the problem of fixed test equipment size. Users can freely assemble the number of units according to the size of the device to be tested (e.g., electrochromic glass), achieving rapid adaptation from small samples to large components.
[0058] It should be noted that the extension and fixing method of the fastener 11 in the second direction x and the third direction y are also not limited.
[0059] In one possible implementation, the fastener unit 111 includes a first protrusion and a first receiving groove disposed on both sides of the direction of the straight line containing the second direction x;
[0060] This allows the first protrusion of one fastener unit 111 and the first receiving groove of another fastener unit 111 to cooperate with each other, thereby achieving a fixed connection between the two fastener units 111 in the second direction x.
[0061] The mating structure between the protrusion and the receiving groove allows the fastener unit 111 to be quickly positioned and connected in the second direction x. This simplifies the assembly process and avoids errors caused by manual alignment; at the same time, it enhances the shear resistance of the connection nodes and maintains the planar accuracy of the sensor array.
[0062] Similarly, in the third direction y, the fastener unit 111 includes a second protrusion and a second receiving groove provided on both sides of the direction of the straight line in the third direction y;
[0063] This allows the second protrusion of one fastener unit 111 and the second receiving groove of another fastener unit 111 to cooperate with each other, thereby achieving a fixed connection between the two fastener units 111 in the third direction y.
[0064] With the above structure, the fastener 11 can be extended arbitrarily and quickly assembled in the second direction x and the third direction y, thereby realizing rapid adaptation to objects of various sizes to be tested.
[0065] Secondly, the specific arrangement of the sensors 12 is not limited.
[0066] In one possible implementation, when at least one sensor 12 includes a plurality of sensors 12:
[0067] Multiple sensors 12 are evenly arranged on the surface of the fixture 11 facing the object to be detected;
[0068] Alternatively, multiple sensors 12 may be arranged in a ring around the inner periphery of the surface of the fixture 11 facing the object to be detected.
[0069] This can be understood as: this application provides multiple ways to set up the sensor 12. When the area of the object to be detected is small, or although the area is large, but the required detection accuracy is high, multiple sensors 12 can be evenly arranged on the surface of the fixing member 11 facing the object to be detected, so as to collect the optical properties of most or even all of the surface of the object to be detected with high precision.
[0070] When the area of the object to be detected is large and the required detection accuracy is low, multiple sensors 12 can be arranged around the inner periphery of the surface of the fixed member 11 facing the object to be detected. For example, for an object to be detected with a square surface, five sensors 12 can be set, located at the four corners and the center of the object to be detected, so as to obtain the highest possible accuracy measurement results at a lower cost.
[0071] Furthermore, the specific structure of light source 2 is also not limited.
[0072] In one possible implementation, the light source 2 consists of at least one light source module 21; when the at least one light source module 21 includes multiple light source modules 21, the multiple light source modules 21 are arranged sequentially and relatively fixed along the second direction x and / or the third direction y.
[0073] Similar to the aforementioned fastener 11, the modular design of the light source 2 allows for free combination in the planar direction, enabling the illumination area to match different sizes of devices under test. The fixed connection between modules ensures the flatness of the emitting surface, avoiding uneven light spots caused by splicing of light sources.
[0074] Furthermore, the projection of the light source 2 in the first direction z covers more than 3 / 4 of the object to be detected.
[0075] By projecting light source 2 onto the main area of the object under test, the effective detection area of the device is ensured to be in a uniform lighting environment, eliminating measurement deviations caused by insufficient lighting in the edge areas.
[0076] Finally, the testing equipment may also include more structures to enable more functions or to accommodate larger objects to be tested.
[0077] In one possible implementation, the test equipment also includes an electrical signal acquisition module, which is electrically connected to the signal processing module 3.
[0078] By integrating an electrical signal acquisition module into the testing equipment and directly connecting it to the signal processing module 3, accurate synchronous acquisition of electrical parameters and optical signals can be achieved within the testing equipment. This further improves measurement accuracy and convenience.
[0079] In another possible implementation, when the test equipment includes multiple test modules 200, the multiple test modules 200 are arranged sequentially along the second direction x.
[0080] The multiple test modules 200 can be expanded along the second direction x, and the module replication can meet the testing needs of ultra-large-sized devices. The base 4 connecting the modules maintains the integrity of the system and avoids inconsistencies in measurement benchmarks caused by discrete equipment.
[0081] It should be noted that the embodiments of this utility model have better implementability and are not intended to limit this utility model in any way. Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments. However, any modifications or equivalent changes and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
