Description

Technical Field

[0001] This utility model belongs to the field of vehicle headlight testing technology, specifically relating to an isolation device for front and rear chambers in a dual-temperature chamber test and a dual-temperature chamber. Background Technology

[0002] With the rapid development of the automotive industry, automotive lighting technology has also advanced rapidly. To enhance the aesthetics of automotive exterior design, headlight designs are becoming increasingly complex, and development cycles are constantly shortening. To verify the reliability of headlights, a dual-temperature test chamber is needed during the headlight development stage to simulate the heat resistance and anti-fog performance of headlights under different temperature and humidity conditions. The structural feature of the dual-temperature test chamber is that it divides the chamber into two independent temperature zones through an isolation device, simulating the temperature and humidity environment of the headlight's surface (outdoor environment) and back (engine compartment) respectively. The temperature zone on the headlight's lens side is usually called the front cavity, which needs to implement functions such as sunlight exposure, rain, wind exposure, temperature control, and humidity control; the temperature zone on the headlight's housing side is called the rear cavity, which also needs to implement functions such as temperature control and humidity control.

[0003] To accommodate testing scenarios for different types of headlights, isolation curtains and tape are typically used to separate the front and rear chambers of a dual-temperature test chamber. This separation is achieved by attaching the isolation curtains to the headlight covers or rain-testing fixtures that mimic body panels. However, to accommodate different headlight designs, these curtains need to be repeatedly disassembled and replaced, resulting in poor compatibility. Utility Model Content

[0004] The purpose of this invention is to provide an isolation device for separating the chambers before and after a dual-temperature chamber test, as well as a dual-temperature chamber. The segmented zipper design makes the isolation curtain body more adaptable, solving the problem of repeated disassembly and replacement of different curtains in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides an isolation device for the front and rear chambers of a dual-temperature chamber test, comprising:

[0006] The system includes an isolation curtain body and an opening adjustment mechanism. The isolation curtain body has a polygonal test opening at its center. The opening adjustment mechanism includes several segmented zippers connecting the apex of the test opening to the edge of the isolation curtain body. Moving each segmented zipper allows the size of the test opening to match the shape of the lighting fixture. By opening and closing the segmented zippers, the test opening of the isolation curtain body can be adjusted, enabling the shape and size of the test opening to match different vehicle headlight designs, resulting in higher adaptability and eliminating the need for repeated disassembly and replacement of different isolation curtain bodies.

[0007] Furthermore, the isolation curtain body is made of elastic material.

[0008] Furthermore, the isolation curtain body is made of TPU material; TPU material has high elasticity and extensibility, and can conform to various complex curved surfaces after stretching. It also has good resilience and is not easily deformed by repeated opening and closing. In addition, TPU material has good waterproof performance and can effectively isolate the air convection and water vapor penetration between the front and rear cavities.

[0009] Furthermore, the isolation curtain body is provided with a first fixing mechanism; the first fixing mechanism includes: a Velcro strap corresponding to the opening of the segmented zipper; the Velcro strap is located at the edge of the opening of the segmented zipper, so that the isolation curtain body is attached to the surface of the vehicle headlight or rain shower. By setting the Velcro strap, the isolation curtain body is attached to the vehicle headlight or rain shower. The Velcro strap is used for auxiliary fixing of non-metallic areas, facilitating installation and removal.

[0010] Furthermore, a second fixing mechanism is provided around the isolation curtain body; the second fixing mechanism is adapted to adsorb the isolation curtain body onto the dual-temperature test chamber.

[0011] Furthermore, the second fixing mechanism is a magnetic fixing frame. By setting the magnetic fixing frame, the isolation curtain body is magnetically attached to the metal box of the dual-temperature chamber, which facilitates installation and removal.

[0012] Furthermore, a composite magnetic rubber patch is provided at the bottom of the magnetic fixing frame; the composite magnetic rubber patch is easier to install and use, and facilitates timely replacement when the magnetism is insufficient.

[0013] Furthermore, the segmented zipper adopts a horizontal or diagonal layout.

[0014] On the other hand, this utility model patent also provides a dual-temperature chamber, including: the isolation device for separating the chambers before and after the dual-temperature chamber test.

[0015] The beneficial effects of this utility model are:

[0016] 1. By adjusting the size and shape of the test opening through the opening and closing of the segmented zipper, it can match different styles of car lights, thus achieving higher adaptability and solving the problem of adapting to multiple styles.

[0017] 2. The isolation curtain body is made of TPU material, which can conform to various complex curved surfaces after stretching. It has good resilience and is not easily deformed by repeated opening and closing. In addition, TPU material has good waterproof performance and can effectively isolate the air convection and water vapor penetration between the front and rear cavities.

[0018] 3. The isolation curtain body is installed in the middle of the front and rear chambers of the dual temperature chamber through a magnetic fixing frame. The isolation curtain body is attached to the vehicle lights or tooling through Velcro straps, thereby achieving isolation between the front and rear chambers of the dual temperature chamber, which is convenient for installation and disassembly and can significantly shorten the test changeover time.

[0029] like Figure 1As shown, this embodiment provides an isolation device for separating the front and rear chambers of a dual-temperature chamber test, including: an isolation curtain body 1 and an opening adjustment mechanism 2; the isolation curtain body 1 has a polygonal test opening 11 at its center; the opening adjustment mechanism 2 includes: a plurality of segmented zippers 21 connecting the vertices of the test opening 11 to the edge of the isolation curtain body 1; moving each of the segmented zippers 21 allows the size of the test opening 11 to be adapted to the shape of the lamp. By opening and closing each segmented zipper 21, the test opening of the isolation curtain body 1 is adjusted, so that the shape and size of the test opening can match different vehicle lamp shapes, resulting in higher adaptability and eliminating the need for repeated disassembly and replacement of different isolation curtain bodies 1.

[0030] The test opening 11 can be, but is not limited to, a quadrilateral, a hexagon, etc. Any even-numbered polygon with more than four sides can be used. Preferably, the test opening 11 is set as a quadrilateral, which makes the force distribution more uniform.

[0031] In this embodiment, the isolation curtain body 1 is made of an elastic material. Preferably, the isolation curtain body 1 is made of TPU material. TPU material has high elasticity and extensibility, and can conform to various complex curved surfaces after stretching.

In addition, TPU material has good waterproof performance, which can effectively isolate the air convection and water vapor penetration between the front and rear cavities.

[0032] Optionally, the isolation curtain body 1 is provided with a first fixing mechanism 3; the first fixing mechanism 3 includes: a Velcro strap 31 corresponding to the opening of the segmented zipper 21; the Velcro strap 31 is located at the edge of the opening of the segmented zipper 21, so that the isolation curtain body 1 is attached to the surface of the vehicle headlight or rain shower. By setting the Velcro strap 31, the isolation curtain body 1 is attached to the vehicle headlight or rain shower. The Velcro strap 31 is used for auxiliary fixing of non-metallic areas, which facilitates installation and removal.

[0033] Optionally, a second fixing mechanism 4 is provided around the perimeter of the isolation curtain body 1; the second fixing mechanism 4 is suitable for adsorbing the isolation curtain body 1 onto the dual-temperature test chamber.

[0034] In this embodiment, the second fixing mechanism 4 is a magnetic fixing frame 41. By setting the magnetic fixing frame 41, the isolation curtain body 1 is magnetically attached to the metal box of the dual-temperature chamber, which facilitates installation and disassembly.

[0035] Preferably, the bottom of the magnetic fixing frame 41 is provided with a composite magnetic rubber sticker, which makes the installation and use of the composite magnetic rubber sticker more convenient and facilitates timely replacement when the magnetism is insufficient.

[0036] In this embodiment, the segmented zipper 21 is arranged horizontally.

The magnetic fixing mechanism 3 adsorbs and installs the isolation curtain body 1 between the front and rear chambers of the dual-temperature chamber, making disassembly easier when adapting to different vehicle headlight shapes and saving significant operation time. The Velcro straps 22 secure the isolation curtain body 1 to the vehicle headlight or rain gear. Used for auxiliary fixation in non-metallic areas, it is compatible with different sized vehicle lights and is easy to install and disassemble. The isolation curtain body 1 is made of TPU material, which has high elasticity and extensibility. After stretching, it can conform to various complex curved surfaces and has good resilience. It is not easily deformed by repeated opening and closing. In addition, TPU material has good waterproof performance and can effectively isolate the air convection and water vapor penetration between the front and rear chambers. By setting up a magnetic fixing frame 31, the isolation curtain body 1 is magnetically adsorbed onto the metal box of the dual temperature chamber, which is convenient for installation and disassembly and can significantly shorten the test changeover time.
