Description

Technical Field

[0001] This application relates to the field of ultraviolet aging test equipment technology, and more specifically, to an ultraviolet aging simulation test device for automotive parts. Background Technology

[0002] With the rapid development of the automotive industry, the durability and reliability of automotive components under various environmental conditions are receiving increasing attention. Ultraviolet (UV) aging simulation testing, as an important accelerated aging test method, is widely used to evaluate the performance changes of automotive components under natural sunlight conditions. Traditional UV aging simulation testing equipment typically simulates UV radiation from natural sunlight, combined with environmental factors such as humidity, to conduct accelerated weathering tests on materials to obtain results on the material's weather resistance and lifespan aging.

[0003] Currently, existing UV aging simulation testing devices for automotive parts have some technical problems in practical applications. Firstly, the UV lamp, as the core component of the equipment, typically has a short lifespan, generally around 1600-2000 hours. Since UV lamps are consumables, they need to be replaced periodically to maintain test results. However, in existing devices, the protective shell of the UV lamp is mostly fixed with screws. This structure is cumbersome to disassemble and install, requiring tools and increasing maintenance difficulty and time costs. Utility Model Content

[0004] To overcome the above deficiencies, this application provides an ultraviolet aging simulation test device for automotive parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] An ultraviolet aging simulation test device for automotive parts includes a test chamber and a hinged door at the opening of the test chamber. The test chamber is characterized by the following features: the interior of the test chamber is divided from top to bottom into an ultraviolet emission area, an aging simulation test area, and a condensation environment component; the inner sidewalls of the test chamber and the hinged door are integrally formed with a mirror panel; the ultraviolet irradiation end of the ultraviolet emission area is equipped with an ultraviolet lamp protection component; the outer wall of the ultraviolet lamp protection component is slidably connected to the ultraviolet emission area and the mirror panel; the aging simulation test area contains a loading component for holding automotive parts; and the sidewall of the test chamber has an exhaust port connected to the interior of the aging simulation test area.

[0007] Furthermore, the ultraviolet emission area integrates a control module and an ultraviolet lamp. The control module is located at the top of the test chamber and has a lamp holder. The ultraviolet lamp is installed inside the lamp holder and is electrically connected to the control module. The ultraviolet light from the ultraviolet lamp irradiates the interior of the aging simulation test area.

[0008] Furthermore, the condensation environment component includes a heating module and a water tank. The heating module is located at the bottom of the test chamber, and the water tank is located on the heating module. The water tank is filled with pure water.

[0009] Furthermore, the mirror panel is made of an alloy substrate and is aluminum-plated and polished, and is integrally formed with the test chamber and the interior of the opening and closing door.

[0010] Furthermore, the ultraviolet lamp protection component includes a transparent plate, a sealing gasket, and an inner groove. The edge of the transparent plate is bonded to the bottom of the sealing gasket, and the inner groove is provided on the outer bottom. The sealing gasket has sliding grooves at both ends. The top of the control module has arc strips that match the sliding grooves at both ends. The mirror panel, which is integrally formed on the inner sidewall of the test chamber, has an insertion groove at its top. The bottom two ends of the transparent plate are inserted into the insertion groove, and the top is attached to the bottom of the control module through the sealing gasket. The sliding groove and the arc strip are slidably connected.

[0011] Furthermore, the loading component includes two support blocks and a loading rack. Two support blocks are respectively provided on both sides of the aging simulation test area. The loading rack is placed inside the aging simulation test area, and its bottom ends are respectively attached to the tops of the two support blocks.

[0012] Furthermore, the exhaust port has an N-shape inside and is interconnected with the interior of the aging simulation test area.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model's ultraviolet lamp protection component uses a combination of a transparent plate and a sealing gasket. The transparent plate effectively isolates the ultraviolet lamp from the test environment, preventing the lamp from being contaminated or damaged, while the sealing gasket ensures good sealing performance and prevents ultraviolet leakage. The transparent plate connects to the test chamber and control module via insertion slots and sliding grooves, making installation and disassembly convenient and facilitating regular cleaning or replacement of the lamp, thus reducing maintenance costs and time.

[0015] 2. The inner walls of the test chamber and the hinged door of this utility model are made of aluminum-plated and polished alloy substrate mirror panel. Aluminum has a high reflectivity in the ultraviolet band (especially UVA and UVB), which can effectively reflect ultraviolet rays, reduce energy loss, ensure uniform distribution of ultraviolet rays in the aging simulation test area, and improve the accuracy and repeatability of test results. The mirror panel is integrally formed with the interior of the test chamber and the hinged door, avoiding the light leakage or uneven reflection problems that may be caused by traditional splicing structures, further improving the optical performance of the test device.

[0016] 3. The internal structure of this utility model test chamber is rationally designed, consisting of an ultraviolet emission zone, an aging test zone, and a condensation environment component from top to bottom. During operation, the ultraviolet emission zone emits light that irradiates the load-bearing components and the samples they carry in the aging test zone. Simultaneously, the condensation environment component heats pure water in its internal water tank to generate water vapor, creating a condensation effect within the chamber. This more closely simulates the aging tests experienced by automotive parts in real-world usage environments. Attached Figure Description

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] Example:

[0025] Please see Figure 1 , Figure 2 , Figure 3 A simulated ultraviolet aging test device for automotive parts includes a test chamber 1 and a hinged door 2 at the opening of the test chamber 1.

[0026] The internal space of test chamber 1 is structurally designed, divided into three main functional areas from top to bottom: the ultraviolet emission area 3 at the top, the aging simulation test area 4 in the middle, and the condensation environment component 5 at the bottom. This layered design makes the boundaries of each functional area clear, facilitating separate control and management. In addition, support feet are fixedly installed at the four corners of the bottom of test chamber 1, and four brakeable casters can also be fixedly installed to keep test chamber 1 level.

[0027] The hinged door 2 consists of two independent door panels, each hinged to the side wall of the test chamber 1. This design allows the two doors 2 to open and close around the test chamber 1, facilitating the insertion and removal of automotive parts to be tested. Simultaneously, connecting locks are installed at the opposite edges of the two doors 2 to ensure reliable closure and maintain the airtightness of the test environment.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 An ultraviolet aging simulation test device for automotive parts includes a test chamber 1, which is divided from top to bottom into an ultraviolet emission area 3, an aging simulation test area 4, and a condensation environment component 5. The test chamber 1 and the inner sidewall of the opening and closing door 2 are integrally formed with a mirror panel 6. The ultraviolet irradiation end of the ultraviolet emission area 3 is equipped with an ultraviolet lamp protection component 7. The outer wall of the ultraviolet lamp protection component 7 is slidably connected to the ultraviolet emission area 3 and the mirror panel 6. The aging simulation test area 4 is equipped with a carrying component 8, which holds automotive parts. The side wall of the test chamber 1 has an exhaust port 9, which is connected to the interior of the aging simulation test area 4. The ultraviolet emission area 3 is composed of a control module 31 and an ultraviolet lamp tube 32. The condensation environment component 5 includes a heating module 51 and a water tank 52. The ultraviolet lamp protection component 7 includes a transparent plate 71, a sealing gasket 72, and an inner groove 73. The carrying component 8 includes two support blocks 81 and a carrying rack 82.

[0029] The ultraviolet (UV) emission area 3 is the core component of this test setup, responsible for generating and controlling UV radiation to simulate the UV components of natural sunlight. A control module 31 is installed at the top inner interior of the test chamber 1. This control module 31 typically includes a power conversion circuit, a timing controller, and electronic components such as a ballast or trigger for driving the UV lamps 32. It is fixed in a suitable position at the top for easy wiring and heat dissipation. Adjacent to the control module 31, the top plate of the test chamber 1 has several precisely matched lamp holders. The UV lamps 32 are installed inside the lamp holders. The lamps are electrically connected to the control module 31 through the lamp holders, ensuring stable and safe operation. The installation direction of the UV lamps 32 is designed so that the emitted UV radiation beam is precisely directed towards the interior space of the adjacent aging simulation test area 4 below. In this way, the load-bearing component 8 and its automotive parts placed in the aging simulation test area 4 are uniformly irradiated from the UV emission area 3 above, thus initiating the simulated UV aging process. By operating the control module 31, the opening and closing, working time, and output intensity of the ultraviolet lamp 32 can be set and controlled, such as by frequency modulation or graded control, to adapt to the testing needs of different materials and different aging degrees.

[0030] The aging simulation test area 4 is defined as the core chamber within the device for performing aging simulation testing of automotive parts. Radiation energy generated by the ultraviolet emission area 3 is projected onto this area, providing ultraviolet aging conditions for the samples. Furthermore, the condensation environment component 5 also acts on this area, increasing internal humidity to reproduce the complex environmental factors of alternating heat and humidity.

[0031] The condensation environment component 5 is a key part for simulating a humid and hot environment. It increases the humidity within the aging simulation test area 4 by generating water vapor, thus more realistically simulating the humid conditions that automotive parts may encounter in actual use. A heating module 51 is installed at the bottom of the test chamber 1. Above the heating module 51, a water tank 52 is integrated. This water tank 52 is typically made of heat-resistant and corrosion-resistant materials, and its bottom is either in close contact with the heating module 51 or maintains a suitable distance to facilitate heat transfer. The water tank 52 is designed with an opening for easy filling and removing of water. Before actual use, an appropriate amount of pure water is filled into the water tank 52. Pure water is chosen to avoid sedimentation or contamination that may occur during heating or evaporation of impurities in the water. When the test requires simulating a humid and hot environment, the control system can activate the heating module 51. The heating module 51 quickly heats the pure water in the water tank 52, generating a large amount of water vapor. This water vapor rises and diffuses into the aging simulation test area 4 above, increasing the air humidity in that area, thus achieving the purpose of simulating humid and hot cyclic aging.

[0032] The mirror panel 6 is a key surface structure covering the inner walls of the test chamber 1 and the opening / closing door 2. Its main function is to increase the reflectivity of the internal environment and enhance the uniformity of ultraviolet radiation on the automotive parts. To achieve extremely high reflectivity and a mirror-like surface, the alloy substrate surface undergoes a precise aluminum plating and polishing process. This process typically involves vacuum evaporating a high-purity aluminum film onto the substrate surface, followed by fine mechanical or chemical polishing, ultimately forming an extremely smooth, flat surface with a reflectivity close to that of a mirror.

[0033] The UV lamp protection component 7 is a key protective structure located in the UV emission area 3. Its main function is to protect the UV lamp tube 32 below from direct physical damage, while allowing UV light to pass through and irradiate the sample. It is also designed for easy disassembly and replacement. The transparent plate 71 is the core component that directly covers the UV lamp tube 32. It is usually made of a material with high light transmittance and resistance to UV aging. Its surface needs to be kept highly clean and transparent to ensure effective UV transmission. The sealing gasket 72 is usually made of aging-resistant, highly elastic silicone or rubber material. It is cleverly designed into the surface edge area of ​​the transparent plate 71, and its bottom is pre-attached to the transparent plate 71. Precisely sized grooves are also pre-made at both ends of the surface of the sealing gasket 72 for subsequent sliding installation. An inner groove 73 is also machined on the outer bottom edge of the transparent plate 71, allowing the user to easily pull out the transparent plate 71 through the inner groove 73. At both ends of the inner top surface of the control module 31, arc-shaped protrusions, or "arc strips," are correspondingly provided to precisely match the grooves on the sealing gasket 72. These two arc strips not only provide sliding guidance but may also play a certain limiting role in the final position. The top of the mirror panel 6, integrally formed on the inner wall of the test chamber 1, has insertion slots that match the shape and size of the bottom ends of the transparent plate 71. During installation: First, align the bottom ends of the transparent plate 71 and insert it into the insertion slots at the top of the mirror panel 6 to achieve initial positioning. Then, push the transparent plate 71 upwards so that the sealing gasket 72 on its top contacts the bottom of the control module 31. At this time, the groove on the sealing gasket 72 will slide along the arc strip on the top of the control module 31 until the groove slides to the end of the arc strip or the predetermined position. At this point, the sealing gasket 72 fits tightly against the bottom of the control module 31, thus securely installing the entire UV lamp protection component 7 into place. This plug-and-slide connection design allows the protection component to be relatively easily removed when cleaning or replacement is required.

[0034] The loading component 8 is a key structure for placing the automotive parts to be tested. It ensures that the samples can be placed stably and orderly within the aging simulation test area 4, and are within the effective range of ultraviolet light and condensation environment. Two support blocks 81 are symmetrically fixed on both sides inside the aging simulation test area 4. These support blocks 81 are typically made of corrosion-resistant and sufficiently strong materials, and their structure is designed to be securely fixed to the side walls or specific positions at the bottom of the test area 4. The top of the support blocks 81 is machined into a flat support surface to support the loading rack 82. The loading rack 82 is a platform for directly placing the automotive parts. It is typically designed with a grid structure to facilitate ultraviolet irradiation and air circulation and moisture penetration within the chamber. The material of the loading rack 82 also needs to consider corrosion resistance and aging resistance. In use, the loading rack 82 is placed in the internal space of the aging simulation test area 4, with its bottom ends precisely fitting against the top planes of the two support blocks 81. This bonding method allows the carrier 82 to be stably suspended within the test area 4, without directly contacting any water accumulation at the bottom of the chamber, while ensuring that the sample is placed at a height suitable for receiving uniform irradiation from the ultraviolet emission area 3 above, and within an area where condensation can effectively act.

[0035] Among them, the exhaust port 9 is the channel used by the test chamber 1 to discharge air, water vapor and any gases that may be generated in the aging simulation test area 4. Its unique N-shaped design is designed to optimize the flow path of the internal airflow, improve exhaust efficiency and may help control the microenvironment of the test area.

[0036] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
