Description

Technical Field

[0001] This application relates to the field of vehicle lamp sealing test technology, and more specifically, to a vehicle lamp rain-weather sealing test device. Background Technology

[0002] In automotive lighting systems, the sealing performance of headlights plays a crucial role in their performance and lifespan. With the continuous development of the automotive industry, consumers have increasingly higher requirements for vehicle safety and reliability. Ensuring that headlights can maintain good sealing performance in various harsh environments, especially in rainy weather, has become a key aspect of the design and manufacturing process of automotive lighting fixtures.

[0003] Traditional methods for testing the rain-resistant sealing of vehicle lights have many limitations. In previous tests, the lights were often fixed in a specific position and angle, resulting in a relatively simple testing environment. However, in actual vehicle driving scenarios, the direction of rainfall is not constant, wind direction is complex and variable, and the vehicle itself is in motion, with its direction of travel significantly affecting the contact angle and force between the rain and the lights. For example, when a vehicle is traveling at high speed, even in light rain, the impact angle and speed of the rain relative to the lights change considerably due to the vehicle's rapid movement. In strong winds, the rain can create oblique or even lateral impacts. When a vehicle is turning, climbing, or descending, the vehicle's posture changes, and the pitch and tilt angles of the lights also change accordingly, making the contact between the rain and the lights even more complex and diverse.

[0004] Traditional testing methods using fixed positions and angles cannot comprehensively and realistically simulate the rain damage faced by vehicle lights in actual driving environments, leading to significant discrepancies between test results and real-world usage. This can cause some vehicle lights that appear to have satisfactory sealing performance in traditional tests to experience water ingress and fogging during actual use, severely impacting their illumination performance, reducing vehicle safety in rainy weather, shortening their lifespan, increasing after-sales maintenance costs, and posing risks to users.

[0005] Therefore, this application proposes a vehicle headlight rain-weather sealing test device to solve the above-mentioned problems. Utility Model Content

[0006] To address the aforementioned issues, this application provides a vehicle headlight rain-weather sealing test device.

[0007] The technical solution of the vehicle headlight rain-weather sealing test device provided in this application is as follows:

[0008] A vehicle headlight rain-weather sealing test device includes a base and linear motor units. The linear motor units are symmetrically arranged at the left and right ends of the base. Each linear motor unit has two linear motors. The piston rods of adjacent linear motor units are movably connected by linkage rods. A fixing plate is provided on the top of the adjacent linkage rods, and a fixing component is provided on the fixing plate.

[0009] Furthermore, the base is provided with longitudinally rotating shaft assemblies at both ends, and the shaft assemblies are laterally rotatably connected to the bottom of the linear motor assembly.

[0010] The above technical solution enables the linear motor unit to achieve multi-directional rotation adjustment on the base, thereby flexibly changing the posture of the linkage and the fixed plate. It can not only adjust the pitch angle, but also adjust the tilt angle in the left and right directions. It can more comprehensively simulate the actual angle changes of the car lights under different driving conditions (such as turning, going uphill and downhill, tilting, etc.), greatly improving the simulation realism of the test device to the actual driving environment, and ensuring the accuracy and reliability of the test results of the car light sealing performance in rainy weather.

[0011] Furthermore, the arrangement of the fasteners matches the fixing points of the test vehicle lights, and the fasteners are detachably mounted on the fixing plate.

[0012] The above technical solution facilitates the quick replacement of suitable fasteners for different models and specifications of vehicle lights, improving the versatility and adaptability of the device. It can meet the testing needs of various types of vehicle lights and reduce the cost and time required to redesign or modify the device due to differences in vehicle lights.

[0013] Furthermore, the fixing plate is a transparent structure.

[0014] The above technical solution allows testers to directly observe the inside (back) of the headlight during testing without the need for additional complex observation equipment or disassembly devices. It enables timely detection of phenomena such as water ingress or fogging inside the headlight, improving testing efficiency and convenience. Furthermore, it facilitates real-time monitoring and recording of potential problems during testing.

[0015] Furthermore, the fixing plate and the linkage rod are an integral structure.

[0016] The above technical solution enhances the stability and firmness of the connection between the fixing plate and the linkage rod, reduces test errors that may be caused by loosening or shaking of the connection, and ensures that the headlight can always maintain a stable fixed state during the adjustment of the fixing plate angle and the testing process, thereby improving the accuracy and reliability of the test data.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) The test device can adjust the angle of the fixed plate in multiple dimensions, including the pitch angle and the left and right tilt angle, which highly simulates the angle change of the car headlights under various postures in actual driving, making the test environment closer to the real situation, effectively improving the accuracy of the rainy weather sealing test of the car headlights, and providing a reliable basis for the quality assessment of the car headlights.

[0019] (2) The mounting plate can be adjusted by adjusting the height of the linear motor to raise the mounting plate's elevation angle, making the mounting plate as horizontal as possible, which is convenient for the tester to install and remove the vehicle lights. Attached Figure Description

[0026] Example:

[0027] The following is in conjunction with the appendix Figure 1 -2 provides further detailed description of this application.

[0028] This application discloses a vehicle headlight rain-weather sealing test device, including a base and linear motor groups. The linear motor groups are symmetrically arranged at the left and right ends of the base. Each linear motor group has two linear motors. The piston rods of adjacent linear motor groups are movably connected by linkage rods. The top of the adjacent linkage rods is provided with a fixing plate, and the fixing plate is provided with a fixing component.

[0029] See Figure 1 and Figure 2 The base has longitudinally rotating shafts at both ends, which are laterally connected to the bottom of the linear motor unit. This allows the linear motor unit to rotate in multiple directions on the base, thus flexibly changing the posture of the linkage and the fixed plate. It can not only adjust the pitch angle but also adjust the tilt angle in the left and right directions. This can more comprehensively simulate the actual angle changes of the car lights under different driving conditions (such as turning, going uphill and downhill, and tilting), greatly improving the simulation realism of the test device to the actual driving environment and ensuring the accuracy and reliability of the test results of the car light sealing performance in rainy weather.

[0030] See Figure 1 and Figure 2 The arrangement of the fasteners matches the mounting points of the test vehicle lights, and the fasteners are detachably mounted on the mounting plate; this allows for quick replacement of suitable fasteners for different models and specifications of vehicle lights, improving the versatility and adaptability of the device, meeting the testing needs of various types of vehicle lights, and reducing the cost and time required to redesign or modify the device due to differences in vehicle lights.

[0031] See Figure 1 and Figure 2 The mounting plate is transparent, allowing testers to directly observe the interior (back) of the headlight during testing without the need for additional complex observation equipment or disassembly devices. This enables timely detection of issues such as water ingress or fogging inside the headlight, improving testing efficiency and convenience. It also facilitates real-time monitoring and recording of potential problems during testing.

[0032] See Figure 1 and Figure 2 The fixing plate and the linkage rod are integrated into one structure, which enhances the stability and firmness of the connection between the fixing plate and the linkage rod, reduces the test error that may be caused by loosening or shaking of the connection parts, and ensures that the headlight can always maintain a stable fixed state during the adjustment of the fixing plate angle and the test process, thereby improving the accuracy and reliability of the test data.

[0033] The implementation principle of the vehicle headlight rain-weather sealing test device in this application embodiment is as follows:

[0034] First, based on the model of the test headlight, select appropriate mounting hardware and install it on the mounting plate. Then, fix the headlight to the mounting plate using the mounting hardware. By controlling the extension and retraction of each linear motor in the linear motor assembly, and since there are linkage rods connecting the piston rods of adjacent linear motor assemblies, the extension and retraction of the linear motors will drive the linkage rods to move, thereby allowing the mounting plate to adjust its height and a certain degree of pitch angle. At the same time, the rotating shafts at both ends of the base are connected to the rotating base at the bottom of the linear motor assembly, allowing the linear motor assembly to rotate longitudinally around the rotating shafts, thereby driving the mounting plate to adjust its tilt angle in the left and right directions. After adjusting the angle of the mounting plate, activate the simulated rain device to conduct a rain-day sealing test on the headlights fixed to the mounting plate in different postures. During the test, the internal condition of the headlights can be directly observed through the transparent mounting plate to determine whether its sealing performance meets the requirements.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
