Description

Technical Field

[0001] This utility model relates to the field of exterior window optical technology, and more specifically, to a comprehensive testing device for the optical performance of finished exterior windows. Background Technology

[0002] In today's construction industry, as people's requirements for the quality of living environment continue to increase, the optical performance of building windows is receiving more and more attention. As an important part of the building envelope, windows must not only meet the basic functional requirements of lighting and ventilation, but also have good optical properties such as heat insulation, sun shading, and UV protection to achieve indoor comfort and energy saving. On the one hand, the climate conditions in different regions vary greatly. From the sunny tropical regions to the relatively weak temperate regions, the requirements for lighting and sun shading of windows are completely different. In the hot southern regions, windows need to have efficient sun shading performance in summer to block a large amount of solar radiation heat from entering the room and reduce the air conditioning cooling load. In the cold northern regions, windows are expected to bring in sunlight to the maximum extent in winter to increase the indoor temperature and reduce heating energy consumption.

[0003] However, if the testing equipment cannot directly clamp the exterior windows and can only be tested at a fixed station in the laboratory, it means that a large number of exterior windows actually installed on the exterior walls cannot be conveniently tested. For some renovation projects of old buildings, it is necessary to evaluate the improvement effect of optical performance after replacing the exterior windows. Since it is not possible to clamp and test on-site, the exterior windows can only be removed and transported to the laboratory. This not only consumes a lot of manpower and resources, but may also damage the exterior windows during the removal process. Moreover, it is impossible to reproduce the real environment on site, and the practicality of the test results is greatly reduced. Fixed-height lighting can only provide light from a single angle and with a single intensity, and cannot simulate the changes in the sun's high angle or the diversity of light under different weather conditions. This means that the exterior windows can only be tested under limited lighting conditions, and the evaluation of optical performance such as shading and lighting is not comprehensive. For example, for smart exterior windows with dynamic dimming function, fixed lighting cannot stimulate their adaptive adjustment ability under different light intensities. The test results cannot reflect the real performance of the exterior windows and mislead product development and application.

[0004] Therefore, a comprehensive testing device for the optical performance of finished exterior windows is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a comprehensive testing device for the optical performance of finished exterior windows. By adjusting the cooperation between the various parts of the components, the clamping design greatly simplifies the sample installation process for exterior window testing needs in different building scenarios. Whether it is the exterior window of a high-rise building or the exterior windows of a small residential building scattered on different floors and in different rooms, the operator does not need complicated handling and fixing devices. He can simply clamp the testing device directly onto the exterior window to carry out the test.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A comprehensive testing device for the optical performance of finished exterior windows includes an adjustment component, with a simulated sun lamp at the upper end of the adjustment component and a testing component in the middle of the adjustment component;

[0008] The adjustment assembly includes a mounting frame, inside which a pair of symmetrical sliding blocks are slidably connected. A hydraulic telescopic rod is fixedly connected to the middle of the mounting frame, and a drive block is fixedly connected to the output end of the hydraulic telescopic rod. A connecting rod is fixedly connected to the middle of each pair of sliding blocks.

[0009] Furthermore, the test assembly includes a pair of main connecting frames, which are arranged symmetrically to each other, and the two main connecting frames are respectively fixedly connected to one end of a connecting rod at their respective close ends.

[0010] Furthermore, a protective frame is fixedly connected inside the main connecting frame, a servo motor is fixedly connected to the lower end of the protective frame, a lead screw is fixedly connected to the output end of the servo motor, a threaded sleeve is installed in the middle of the lead screw, a limit block is fixedly connected to the middle of the threaded sleeve, and one end of the limit block is slidably connected to the inner side wall of the main connecting frame.

[0011] Furthermore, a mounting housing is fixedly connected to the middle of one of the screw sleeves, an LED light panel is fixedly connected inside the mounting housing, and adjustment plates are connected to the upper and lower ends of the mounting housing through damping shafts. The middle of the other screw sleeve is fixedly connected to the middle of the simulated sun lamp.

[0012] Furthermore, each pair of sliding blocks is arranged in a triangular shape, and each pair of sliding blocks has a T-shaped groove at one end that is close to each other. Each pair of sliding blocks is fixedly connected to a strip-shaped sliding limit block at both the upper and lower ends.

[0013] Furthermore, both ends of the driving block are inclined, and both ends of the driving block are fixedly connected with T-shaped protrusions. A pair of T-shaped protrusions are slidably connected to a pair of T-shaped grooves respectively.

[0014] Furthermore, the interior of the mounting frame is provided with a strip-shaped sliding groove that slides in conjunction with the strip-shaped sliding limit block.

[0015] In summary, this utility model has the following beneficial effects:

[0016] (1) By adjusting the mutual cooperation between the various parts of the components, this solution can greatly simplify the sample installation process for the testing needs of exterior windows in different building scenarios. Whether it is the exterior windows of high-rise buildings or the exterior windows of small residential buildings scattered on different floors and in different rooms, the operators do not need complicated handling and fixing devices. They can simply clamp the test device directly on the exterior window to carry out the test, saving a lot of installation and debugging time and improving testing efficiency. It is especially suitable for large-scale exterior window sampling projects and can quickly complete the optical performance testing of multiple exterior windows.

[0017] (2) This scheme uses the cooperation between the various parts of the test components to simulate the changing solar altitude angle throughout the day. The angle of incidence and intensity of sunlight on the windows vary significantly in different seasons and at different times. The adjustable lighting height function can accurately simulate this natural phenomenon. For example, when testing the shading performance in summer, the lighting can be raised to increase the angle of incidence and simulate the strong afternoon light. When testing the lighting in winter, the lighting can be lowered to simulate the warm light at a low angle. This allows the optical performance of the windows to be fully tested under various simulated lighting scenarios, just as if the windows were experiencing the changing seasons and the alternation of day and night in the actual use environment.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figures 1-5 As shown, a comprehensive testing device for the optical performance of a finished window is provided in a preferred embodiment of the present invention. It includes an adjustment component 1, a simulated sun lamp 2 at the upper end of the adjustment component 1, and a testing component 3 in the middle of the adjustment component 1.

[0027] The adjustment component 1 includes a mounting frame 101, a pair of vertically symmetrical sliding blocks 102 are slidably connected inside the mounting frame 101, a hydraulic telescopic rod 103 is fixedly connected to the middle of the mounting frame 101, a drive block 104 is fixedly connected to the output end of the hydraulic telescopic rod 103, and a connecting rod 105 is fixedly connected to the middle of each pair of sliding blocks 102.

[0028] This solution serves as the basic framework for the entire adjustment assembly 1, providing a stable installation support environment for all internal components. The internally designed strip-shaped sliding groove precisely matches the strip-shaped sliding limit block on the sliding block 102, ensuring that the sliding block 102 can only slide smoothly and accurately in the predetermined direction without any deviation or jamming. This lays a solid foundation for the subsequent precise clamping of the outer window and adjustment test device, ensuring the stability and reliability of the entire testing process.

[0029] Reference Figures 1-5 As shown, the test assembly 3 includes a pair of main body connecting frames 301, which are arranged symmetrically to each other. The two main body connecting frames 301 are fixedly connected to one end of the connecting rod 105 at their respective close ends.

[0030] Reference Figures 1-5 As shown, a protective frame 302 is fixedly connected inside the main connecting frame 301. A servo motor 303 is fixedly connected to the lower end of the protective frame 302. A lead screw 304 is fixedly connected to the output end of the servo motor 303. A threaded sleeve 305 is installed in the middle of the lead screw 304. A limit block 306 is fixedly connected to the middle of the threaded sleeve 305. One end of the limit block 306 is slidably connected to the inner side wall of the main connecting frame 301.

[0031] Reference Figures 1-4 As shown, a mounting housing 307 is fixedly connected to the middle of one of the screw sleeves 305, an LED light board 308 is fixedly connected inside the mounting housing 307, and an adjustment plate 309 is connected to both the upper and lower ends of the mounting housing 307 through a damping shaft. The middle of the other screw sleeve 305 is fixedly connected to the middle of the simulated sun lamp 2.

[0032] This solution uses a pair of main connecting frames 301 symmetrically arranged to form a stable support structure, providing an installation platform for internal components. One end of the frame is fixedly connected to the connecting rod 105, closely receiving the motion state transmitted from the adjustment component 1, ensuring that the test component 3 and the adjustment component 1 are linked and coordinated, accurately responding to the outer window clamping action, providing a stable foundation for subsequent illumination simulation and optical performance testing, and ensuring that the relative positions of each component remain stable during the test.

[0033] Reference Figures 1-3 As shown, a pair of sliding blocks 102 are arranged in a triangular shape, and a T-shaped groove is provided at one end of each pair of sliding blocks 102 that is close to each other. A strip-shaped sliding limit block is fixedly connected to the upper and lower ends of the pair of sliding blocks 102.

[0034] Reference Figures 1-3 As shown, both ends of the drive block 104 are inclined, and both ends of the drive block 104 are fixedly connected with T-shaped protrusions. A pair of T-shaped protrusions are slidably connected to a pair of T-shaped grooves respectively.

[0035] Reference Figures 1-3 As shown, the mounting frame 101 has a strip-shaped sliding groove inside that slides in conjunction with the strip-shaped sliding limit block;

[0036] This solution uses a hydraulic telescopic rod 103 as a power source, possessing a powerful thrust output capability and capable of precise extension and retraction according to control commands. The drive block 104 connected to its output end features an ingeniously designed combination of beveled ends and T-shaped protrusions. The beveled ends cooperate with the T-shaped groove of the sliding block 102. When the hydraulic telescopic rod 103 extends or retracts, the drive block 104 pushes or pulls the sliding block 102, achieving rapid and stable clamping of the outer window frame. The sliding connection between the T-shaped protrusion and the T-shaped groove ensures effective force transmission and prevents the drive block 104 from disengaging from the sliding block 102, guaranteeing the continuity and reliability of the clamping action and adapting to the clamping needs of outer windows of different materials and sizes.

[0037] Specific implementation process: First, when optical performance testing of the finished exterior window is required, the test device is first installed on the exterior window using the adjustment component 1. The mounting frame 101 serves as the basic frame, and a pair of symmetrical sliding blocks 102 inside it plays a crucial role. The sliding blocks 102 are triangular in shape, which not only makes the structure more stable but also facilitates sliding within the mounting frame 101. The strip-shaped sliding limit blocks fixedly connected to the upper and lower ends of the sliding blocks 102 tightly cooperate with the strip-shaped sliding grooves inside the mounting frame 101, ensuring that the sliding blocks 102 can only slide smoothly along the predetermined direction without deviation or wobbling. During installation, the hydraulic telescopic rod 103 located in the middle of the mounting frame 101 is activated. The drive block 104 at the output end moves accordingly. Both ends of the drive block 104 are beveled and fixedly connected to T-shaped protrusions. These T-shaped protrusions and sliding blocks 102 are precisely slidably connected to the T-shaped grooves at one end. When the hydraulic telescopic rod 103 extends, the drive block 104 pushes outward. Utilizing the cooperation of the beveled surfaces, T-shaped protrusions, and T-shaped grooves, a pair of sliding blocks 102 are forced to slide in opposite directions, thus clamping the outer window frames of different sizes. By controlling the extension stroke of the hydraulic telescopic rod 103, the clamping force can be precisely adjusted, ensuring the test device is firmly fixed to the outer window while avoiding damage to the window due to excessive clamping. It is suitable for various materials such as aluminum alloy, PVC, and wood. The test component 3 was tested... During the process, it is responsible for simulating different lighting conditions and detecting the optical response of the outer window. A pair of main connecting frames 301 are connected to the sliding block 102 via connecting rods 105 to ensure coordinated operation with the adjustment component 1. The protective frame 302 inside the main connecting frame 301 protects the internal precision components. The servo motor 303 fixedly connected to its lower end is the power source for adjusting the lighting height. After the servo motor 303 starts, it drives the lead screw 304 to rotate. The screw sleeve 305 installed on the lead screw 304 can only move along the axial direction of the lead screw 304 due to the restriction of the limit block 306. One end of the limit block 306 is slidably connected to the inner wall of the main connecting frame 301 to ensure the smooth movement of the screw sleeve 305. The middle part of one of the screw sleeves 305 is fixedly connected to The device is equipped with a mounting housing 307, and an LED light panel 308 is fixedly connected inside the mounting housing 307 to provide auxiliary lighting. The upper and lower ends of the panel are connected to an adjustment plate 309 via a damping shaft, which can manually fine-tune the angle of light as needed to further optimize the lighting effect. The middle of another screw sleeve 305 is fixedly connected to the middle of the simulated sun lamp 2. The height of the simulated sun lamp 2 can be precisely controlled by driving the lead screw 304 to rotate through the servo motor 303. The solar altitude angle changes continuously throughout the day, and the angle of incidence of sunlight and the intensity of light on the external window vary significantly in different seasons and at different times. Using this principle, when testing the sunshade performance in summer, the servo motor 303 is activated to raise the simulated sun lamp 2, increase the angle of incidence, and simulate the high-angle strong light irradiation in the afternoon.During winter lighting tests, the simulated sun lamp 2 was lowered to simulate low-angle warm light incidence, allowing for a comprehensive evaluation of the window's optical performance under various simulated lighting scenarios. This simulates the window's actual usage environment, experiencing seasonal changes and day-night cycles. The photodetector array, not shown in detail in the diagram, was distributed at different positions on the light-receiving side of the window to capture various parameters of the light passing through, such as light intensity, luminous flux, and the distribution of light energy across different wavelengths. The detector's sensitivity and response wavelength range determine the detection accuracy and breadth, thus enabling a comprehensive and accurate evaluation of the window's optical performance.
