[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] An automotive dimming film performance testing device, comprising:

[0032] The test chamber 1 has multiple safety light curtains 3 symmetrically distributed on its upper end, and the test chamber 1 has a test stage assembly 2 for testing the dimming film inside.

[0033] A fixed frame 4 is fixedly connected to the back of the test chamber 1. A main power supply 7 is installed at the bottom of the fixed frame 4. A lifting component 5 for adjusting the height of the test stage assembly 2 is installed inside the fixed frame 4.

[0034] The fixed frame 4 is equipped with a drag chain 6 for protecting the line during lifting. A control cabinet 8 is installed on one side of the test box 1. A display screen 9 is installed on the front of the control cabinet 8. A rotating storage seat 10 is rotatably connected to the front of the control cabinet 8. A three-color light 11 is fixedly connected to the upper end of the control cabinet 8. Multiple footrests 12 are arranged in a ring on the outside of the test box 1.

[0035] For example, the test chamber 1, as the main load-bearing structure of the entire equipment, plays a crucial role. The safety light curtain 3 tests the space above the test chamber 1 in real time. If an object or person accidentally enters the detection area, the safety light curtain 3 will quickly sense it and immediately send a signal to the control system, causing the equipment to stop operating. This effectively avoids safety accidents caused by misoperation or accidental intrusion, providing reliable protection for the personal safety of operators. The interior of the test chamber 1 is the core area for testing. It houses the testing platform assembly 2 for testing the dimming film. The testing platform assembly 2 undertakes key tasks such as placing the dimming film and performing various performance tests. The stability and accuracy of the detection directly affect the reliability of the final test results. The fixed frame 4 provides stable support and installation space for other important components of the equipment. The main power supply 7 is located at the bottom of the fixed frame 4, providing stable and reliable power support for the entire equipment, ensuring that the equipment will not malfunction or be interrupted due to power problems during operation. The lifting component 5 can flexibly adjust the height of the detection stage component 2 according to different detection needs, so that the detection probe can accurately contact different positions of the dimming film, thereby achieving comprehensive and detailed detection. During the lifting and lowering process of the detection stage component 2, the drag chain 6 can orderly store and protect the various components. This system includes various wiring options to prevent tangling and wear caused by frequent movement, ensuring smooth wiring and normal equipment operation. Operators can precisely control and adjust the equipment's operating status and monitoring parameters using various buttons and controllers on control cabinet 8. Display screen 9 shows real-time information such as equipment operating status, monitoring data, and alarm messages, allowing operators to understand the equipment's operation and make appropriate decisions. A rotating storage base 10 stores the keyboard and mouse, allowing for easy access with a simple rotation, improving work efficiency. A tri-color light 11 displays red, yellow, and green lights. The three-color indicator lights 11 serve as the equipment's "status indicator." A solid green light indicates normal operation; a flashing yellow light indicates a reset operation; a solid yellow light indicates the equipment is stopped; and a flashing red light indicates a malfunction. By observing the color changes of the three-color lights 11, operators can quickly understand the equipment's operating status and take appropriate measures. The footrest 12 provides operators with a comfortable standing and operating platform. When performing equipment debugging, diaphragm placement, and other operations, operators can stand on the footrest 12 for more convenient and safer work, improving operational convenience and comfort.

[0036] The testing platform assembly 2 includes a lifting plate 21, a rotating plate 22, a fixed guide rail 25, a fixing component 26, a sliding guide rail 27, a slider 28, and a testing probe 29;

[0037] The test chamber 1 has a sliding connection to a lifting plate 21. Multiple rotating plates 22 are rotatably connected to the side wall of the lifting plate 21. Multiple cylinders 23 are evenly distributed at the lower end of each rotating plate 22. Connectors are hinged to both ends of each cylinder 23. These connectors are fixedly connected to the lifting plate 21 and the rotating plates 22, respectively. Fixed guide rails 25 are fixedly connected to the upper end of each rotating plate 22. Fixing members 26 are provided on the outer side of each fixed guide rail 25. Sliding guide rails 27 are fixedly connected to the side wall of each fixing member 26. Multiple sliders 28 are evenly distributed and slidably connected inside each sliding guide rail 27. Detection probes 29 are installed inside each slider 28. Small electrical boxes 24 are installed at the lower end of each rotating plate 22. These small electrical boxes 24 are electrically connected to the detection probes 29. Fixing bolts 210 are installed inside each slider 28, and these bolts contact the sliding guide rails 27.

[0038] For example, the lifting plate 21 can move up and down in the vertical direction to adjust the height of the detection stage assembly 2. Multiple evenly distributed rotating plates 22 are rotatably connected to the side wall of the lifting plate 21. These rotating plates 22 can rotate around the connection point to change the angle of the detection probe, adapting to the detection requirements of dimming films of different shapes and positions. Multiple cylinders 23 have connecting parts hinged to both ends, and these connecting parts are fixedly connected to the lifting plate 21 and the rotating plates 22 respectively. The extension and retraction of the cylinders 23 can drive the rotating plates 22 to rotate, facilitating operation of the detection stage assembly 2 below. The fixed guide rail 25 provides a stable mounting base for the sliding guide rail 27, and the fixing parts 26 serve to fix and connect the components. The sliding guide rail 27 is securely installed on the fixed guide rail 25. The sliding guide rail 27 provides a sliding track for the slider 28, which can slide back and forth on the sliding guide rail 27 to adjust the position of the detection probe. The detection probe 29 is a key component for performance testing of the equipment. It can accurately measure various performance indicators of the dimming film, such as light transmittance and resistance. Each of the multiple rotating plates 22 has a small electrical box 24 at its lower end. The multiple small electrical boxes 24 are electrically connected to the multiple detection probes 29 to provide a stable power supply to the detection probes 29. By tightening or loosening the fixing bolts 210, the position of the slider 28 on the sliding guide rail 27 can be fixed or adjusted, thereby achieving precise fixing and adjustment of the position of the detection probe 29.

[0039] The lifting assembly 5 includes a fixed frame 51, a motor 52, a screw 53, and a lifting block 54;

[0040] The fixed frame 4 is internally fixedly connected to a fixed bracket 51. The lower end of the fixed bracket 51 is equipped with a motor 52 via a reducer. A screw 53 is fixedly connected to the output end of the reducer. The screw 53 is rotatably connected to the fixed bracket 51. A lifting block 54 is threadedly connected to the outer side of the screw 53. The lifting block 54 is bolted to the lifting plate 21. The lifting block 54 is slidably connected to the fixed bracket 51. Two symmetrically distributed guide pulleys 55 are bolted to the side wall of the lifting plate 21. The two guide pulleys 55 are rotatably connected to the fixed bracket 51 respectively.

[0041] For example, the fixed frame 51 provides a stable support structure for the entire lifting assembly. The motor 52 is the power source of the lifting assembly, which can provide strong driving force to make the lifting block 54 move up and down. When the motor 52 starts, it drives the screw 53 to rotate through the transmission of the reducer. Due to the threaded connection between the screw 53 and the lifting block 54, when the screw 53 rotates, the lifting block 54 will move up and down along the screw 53. The lifting block 54 is connected to the lifting plate 21 by bolts. In this way, the up and down movement of the lifting block 54 will drive the lifting plate 21 to move together, thereby realizing the adjustment of the height of the detection table assembly 2. The lifting block 54 is slidably connected to the fixed frame 51 to ensure the stability and accuracy of the lifting block 54 during the movement. The guide pulley 55 plays a guiding and supporting role. It can guide the lifting plate 21 to move up and down in the correct direction, while reducing the friction between the lifting plate 21 and the fixed frame 51, making the lifting process more stable and smooth.

[0042] Working principle: First, ensure that the main power supply 7 is connected to provide stable power to the equipment. Start the equipment through the control cabinet 8. At this time, the green light in the three-color light 11 will be constantly lit, indicating that the equipment is in normal operation.

[0043] The operator stands on the footrest 12 and, according to the shape and position of the dimming film to be tested, controls the motor 52 to start through the control cabinet 8. The motor 52 drives the screw 53 to rotate through the reducer. Since the screw 53 is threadedly connected to the lifting block 54, the lifting block 54 moves up and down along the screw 53, thereby driving the lifting plate 21, which is bolted to the lifting block 54, to rise and fall, realizing the initial adjustment of the height of the testing table assembly 2. At the same time, the guide pulley 55 guides the lifting plate 21 to move smoothly and reduce friction.

[0044] After adjusting the height of the testing platform assembly, manually place the dimming film on the appropriate position of the rotating plate 22. If it is necessary to further prevent the light-transmitting film on the lower rotating plate 22, the operator controls the cylinder 23 to extend and retract. The connecting parts at both ends of the cylinder 23 are fixed to the lifting plate 21 and the rotating plate 22 respectively. The extension and retraction of the cylinder 23 drives the rotating plate 22 to rotate around the connection point, thereby facilitating the operation of the lower testing platform assembly 2.

[0045] Next, the operator pushes the slider 28 back and forth on the sliding guide rail 27 to precisely adjust the position of the detection probe 29. After adjustment, the fixing bolt 210 is tightened to fix the slider 28 on the sliding guide rail 27. The detection probe 29 then begins to work, accurately measuring various performance indicators of the dimming film, such as light transmittance and resistance, and displays the detection data in real time on the display screen 9. The operator can monitor the detection status by observing the display screen 9.

[0046] If the equipment malfunctions during the test, the red light in the tri-color indicator 11 will flash, and the operator can quickly take corresponding measures. After the test is completed, the equipment can be reset. At this time, the yellow light in the tri-color indicator 11 will flash, the reset is complete, the yellow light will stay on, and the equipment will be in a stopped state.

[0047] In this application, the cylinder 23, small electrical box 24, detection probe 29, safety light curtain 3, motor 52, main power supply 7, and tri-color lamp 11 are controlled automatically by the control cabinet 8. The control circuit of the control cabinet 8 can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
