The platform is used to hold the automotive lamps to be tested, the air blower is used to blow air to the lamps, the spray mechanism is used to spray water droplets on the lamps, and the illumination mechanism is used to illuminate the lamps.

[0004] However, the illumination mechanism of existing fog test chambers is located outside the chamber. The strong ambient light outside the chamber can easily affect the intensity of the light irradiated by the illumination mechanism onto the vehicle lamps, thereby affecting the accuracy of the test results. Furthermore, the illumination mechanism's location outside the chamber easily interferes with the vehicle lamps due to the chamber's structure, making it difficult to adjust the angle of the illumination mechanism on the vehicle lamps and making operation more difficult.

[0005] Therefore, the above problems need to be solved urgently. Utility Model Content

[0006] The purpose of the utility model is to provide a fog test chamber to solve the problem that the ambient light outside the chamber is relatively high, which easily affects the intensity of the light irradiated by the illumination mechanism to the automobile lamp, thereby affecting the accuracy of the test results. At the same time, it solves the problem that the illumination mechanism and the automobile lamp are easily interfered with by the structure of the chamber, making it inconvenient to adjust the angle of the illumination mechanism on the automobile lamp and making the operation difficult.

[0033] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0034] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0035] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0036] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0037] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not use relative terms should also be disclosed as specific values with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0038] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0039] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0040] See also Figures 1 to 4 This embodiment provides a fog test chamber for performing fog tests on automobile lamps. The fog test chamber includes a chamber 1, a carrier 2, a blower mechanism 3, a spray mechanism 4, and an illumination mechanism 5. The temperature inside the chamber 1 is adjustable. The carrier 2 is used to carry the automobile lamps, the blower mechanism 3 is used to blow air to the automobile lamps, the spray mechanism 4 is used to spray water droplets on the automobile lamps, and the illumination mechanism 5 is used to illuminate the automobile lamps.

[0041] The fog test chamber also includes a first carrier rack 6 and a second carrier rack 7. The first carrier rack 6 is slidably arranged in the box body 1 to be close to or away from the carrier 2, and the blowing mechanism 3 and the spraying mechanism 4 are both arranged on the first carrier rack 6. The second carrier rack 7 is arranged in the box body 1 and is located on the side of the first carrier rack 6 away from the carrier 2, and the lighting mechanism 5 is arranged on the second carrier rack 7. It should be noted that the first carrier rack 6 can select any sliding structure in the existing technology to achieve sliding, such as a guide rail structure, a linear slide rail structure, etc., and this embodiment does not make specific requirements and restrictions on this. It should also be noted that the temperature adjustment structure in the box body 1 can select any air-conditioning structure in the existing technology, and the specific model can be selected according to the actual application scenario.

[0042] It is understood that by placing the illumination mechanism 5 on the second support frame 7 located within the housing 1, most of the ambient light outside the housing 1 can be blocked, thereby ensuring the intensity of the light irradiated by the illumination mechanism 5 on the automotive lamp, thereby improving the accuracy of the detection results. In addition, placing the illumination mechanism 5 within the housing 1 can prevent interference between the illumination mechanism 5 and the automotive lamp caused by the structure of the housing 1, making it easier to adjust the angle at which the illumination mechanism 5 irradiates the automotive lamp, and reducing the difficulty of operation.

[0043] It can also be understood that the second carrier 7 is arranged on the side of the first carrier 6 away from the carrier 2, which can reduce or even avoid the situation where the water droplets sprayed by the spray mechanism 4 on the first carrier 6 damage the lighting mechanism 5, thereby helping to improve the service life of the fog test chamber.

[0044] During the actual inspection process, workers are required to go in and out of the box 1 many times to place the car lamps on the carrier 2 or to take out the car lamps on the carrier 2. Therefore, in order to avoid collisions between workers and components such as the spray mechanism 4, the blower mechanism 3, and the illumination mechanism 5 in the box 1 when entering and exiting the box 1, and to improve the convenience of operation. In this embodiment, a partition plate 11 is provided in the box 1 to separate the inner cavity of the box 1 into a test chamber 12 and an equipment chamber 13, and the partition plate 11 is provided with a connecting port connecting the test chamber 12 and the equipment chamber 13. The carrier 2 is located in the test chamber 12, and the blower mechanism 3, the spray mechanism 4, and the illumination mechanism 5 are all located in the equipment chamber 13. The blower mechanism 3, the spray mechanism 4, and the illumination mechanism 5 all supply the corresponding test medium to the car lamps on the carrier 2 through the connecting port.

[0045] In order to further enhance the convenience of adjusting the angle at which the illumination mechanism 5 irradiates the automobile lamp, the carrier 2 includes a test turntable 21 and a test platform 22. The test turntable 21 is disposed in the test chamber 12, and the test turntable 21 is configured to carry and rotate the automobile lamp in a vertical direction. The test platform 22 is disposed in the test chamber 12, and the test platform 22 is configured to carry the automobile lamp. With such an arrangement, the automobile lamp is placed on the test turntable 21, and the angle of the automobile lamp can be adjusted by the test turntable 21, which is more convenient for operation. In addition, the automobile lamp can be placed on the test turntable 21 or the test platform 22 according to different testing requirements. It should be noted that the test turntable 21 can select any one of the rotary drive structures in the prior art, such as a rotary cylinder, a servo motor, etc., which will not be elaborated.

[0046] It's worth noting that the automotive lamp inspection results are evaluated by observing whether fog is generated inside the lamps. To facilitate the acquisition of inspection results, in this embodiment, the fog test chamber also includes an image acquisition mechanism 8 for capturing images of the automotive lamps. This mechanism is mounted on the second support frame 7 and positioned below the illumination mechanism 5. This arrangement minimizes interference with the image acquisition mechanism 8 from other components within the chamber 1. Specifically, it reduces the risk of water droplets from the spray mechanism 4 wetting the image acquisition mechanism 8.

[0047] It should be noted that in this embodiment, the image acquisition mechanism 8 includes a high-definition camera capable of multiple zooms and a universal bracket for mounting the high-definition camera to ensure accurate acquisition of images of the automotive lamps. It should also be noted that the structure and operating principles of the high-definition camera and the universal bracket are prior art and will not be described in detail.

[0048] Generally speaking, the height positions of multiple components in the box 1 corresponding to different test environments also need to be adjusted, such as the spraying angle of the spray mechanism 4, the irradiation angle of the lighting mechanism 5, etc. For this reason, in this embodiment, the heights of the first carrier 6 and the second carrier 7 are adjustable. It should be noted that the height adjustment method of the first carrier 6 and the second carrier 7 can adopt any adjustment method in the existing technology. Taking the first carrier 6 as an example, the first carrier 6 includes a first frame and a second frame that are vertically slidably matched. The first frame is installed on the bottom wall of the box 1, and the multiple components used for detection are all arranged on the second frame. The first frame is driven to slide by a linear drive mechanism such as a linear module arranged on the first frame, so that the height of the first carrier 6 can be adjusted.

[0049] Specifically, the illumination mechanism 5 includes an illumination lamp 51 and a locking member. The illumination lamp 51 is pivotally connected to the second support frame 7, and the locking member is used to lock the illumination lamp. It will be appreciated that rotating the illumination lamp 51 can adjust its illumination angle, which is convenient and simple in structure. It should be noted that the locking member can be a bolt-fixing structure, a pin-fixing structure, or other conventional structures. In this embodiment, the locking member is a bolt-fixing structure, which will not be described in detail.

[0050] It is understood that the water droplets sprayed by the spray mechanism 4 will eventually gather at the bottom of the test chamber 12. Therefore, it is necessary to periodically clean the water gathered at the bottom of the test chamber 12. To this end, in this embodiment, the mist test chamber further includes a water supply mechanism, which is configured to supply water to the spray mechanism 4 and to recover the water sprayed by the spray mechanism 4.

[0051] Specifically, the water supply mechanism includes a circulating water tank 9 and a water chiller. The circulating water tank 9 includes a water storage chamber 91 and a return water chamber 92, and the water storage chamber 91 and the return water chamber 92 are connected. The inlet of the water chiller is connected to the return water chamber 92, and the outlet is connected to the water storage chamber 91, so that the water in the return water chamber 92 is cooled and then supplied to the water storage chamber 91. With such an arrangement, the water sprayed by the spray mechanism 4 can be reused. On the one hand, it can save water resources. On the other hand, there is no need to periodically clean the water gathered at the bottom of the test chamber 12. It can be understood that the water chiller cools the recycled water to ensure that the water droplets sprayed by the spray mechanism 4 meet the detection requirements. It should be noted that the water chiller is a prior art. Of course, the circulating water tank 9 can also be provided with a water replenishment hole for replenishing water, an overflow hole for discharging excess water, etc., which will not be described in detail.

[0052] It should be noted that in this embodiment, the spray mechanism 4 and the air blowing mechanism 3 are both prior art and are not improved upon in this embodiment, so they will not be described in detail. The air blowing mechanism 3 is used to simulate the wind blowing toward the vehicle while it is in motion. However, air will also flow inside the engine compartment when the vehicle is in use, meaning that wind will also blow toward the vehicle's lamps.

[0053] Therefore, to ensure comprehensive testing of automotive lamps, in this embodiment, the fog test chamber further includes an air control mechanism disposed within the test chamber 12. The air control mechanism is configured to blow air toward and draw air from opposing sides of the automotive lamp. Specifically, the air control mechanism includes a blower, with the blower's outlet and inlet corresponding to opposing sides of the automotive lamp. It will be appreciated that the blower's outlet is capable of blowing air, while the blower's inlet is capable of drawing air.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
