[0025] An embodiment of the present invention provides a signal light testing device, which includes: a test box 100 and a cleaning component 200, wherein the test box 100 is provided with a placement cavity for placing the signal light to be tested, the test box 100 is provided with an observation port 101 connected to the placement cavity, and the observation port 101 is covered with an observation baffle 300, and the cleaning component 200 includes a driving mechanism 201 and a wiping mechanism 202, the wiping mechanism 202 is slidably arranged on the test box 100, and the wiping mechanism 202 has a wiping surface that abuts against the observation baffle 300, and the driving mechanism 201 drives the wiping mechanism 202 to move along the surface of the observation baffle 300, so that the wiping mechanism 202 cleans the observation baffle 300.

[0026] Please refer to Figure 1 1 is a perspective view of a signal light testing device provided in an embodiment of the present application. In this embodiment, the signal light testing device is used to test the resistance of signal lights in high and low temperature environments. A test chamber 100 is provided with a cavity for placing the signal light to be tested. The test chamber 100 also has an observation port 101, which is covered by a transparent observation baffle 300, allowing the operator to observe the operating status of the signal light in real time during testing. The observation baffle 300 acts as a seal, creating a relatively closed test space within the test chamber 100. The test environment is created by heating or cooling the test space, and the high and low temperature resistance of the signal light is tested by observing the operating status of the signal light within the test chamber 100 under high and low temperature conditions. It is understood that during low-temperature testing, due to the rapid drop in temperature within the test chamber 100, water vapor in the air condenses and adheres to the inner walls of the test chamber 100. When a large number of water droplets condense on the observation baffle 300, they block the observation baffle 300, hindering the operator's view of the signal light inside. Therefore, the test chamber 100 is provided with a cleaning assembly 200 for wiping the observation baffle 300. The cleaning assembly 200 includes a drive mechanism 201 and a wiping mechanism 202 disposed on the observation baffle 300. The wiping surface of the wiping mechanism 202 abuts against the side of the observation baffle 300 located inside the test chamber 100. The drive mechanism 201 cooperates with the wiping mechanism 202 to drive the wiping mechanism 202 along the surface of the observation baffle 300, thereby wiping condensed water droplets on the observation baffle 300, ensuring that the observation baffle 300 is clean and prevents the tester from viewing the signal light inside the test chamber 100. In this embodiment, the cleaning assembly 200 is disposed inside the test chamber 100. The drive mechanism 201 drives the wiping mechanism 202 to move, thereby automatically cleaning the observation baffle 300 without opening the test chamber 100. This ensures a stable test environment and prevents inaccurate test results caused by the temperature inside the test chamber 100 being affected by opening the test chamber 100.

[0027] Optionally, in some possible embodiments, the wiping mechanism 202 includes a cleaning bar 2021 and a moving block 2022, the moving block 2022 is slidably set on the test box 100, and the moving block 2022 is driven by the driving mechanism 201, the cleaning bar 2021 is set on the moving block 2022, and the cleaning bar 2021 is against the surface of the observation baffle 300.

[0028] Please refer to Figure 1 As shown, the cleaning strip 2021 can be made of a sponge or cloth, or other cleaning material. The cleaning strip 2021 is mounted on a movable block 2022. The movable block 2022 moves along the viewing bezel 300, driving the cleaning strip 2021 to wipe the viewing bezel. The cleaning strip 2021 is detachably connected to the movable block 2022, facilitating replacement of the cleaning strip 2021. The cleaning strip 2021 is used to clean accumulated water droplets from the viewing bezel 300. Over time, if the cleaning strip 2021 absorbs excessive water, its wiping effectiveness may be reduced. In this case, the cleaning strip 2021 can be promptly replaced to ensure the cleaning efficiency of the cleaning assembly 200.

[0029] Optionally, in some possible embodiments, the driving mechanism 201 includes a driving motor 2013 and a driving screw 2011, the driving screw 2011 is rotatably arranged on the test box 100, the rotating shaft of the driving motor 2013 is connected to the driving screw 2011, and a first screw hole is opened on the wiping mechanism 202, and the driving screw 2011 is passed through the first screw hole.

[0030] Please refer to Figure 1 and Figure 2 As shown, a drive screw 2011 is disposed horizontally or vertically on the test chamber 100. A first screw hole is defined at one end of the movable block 2022, which engages with the drive screw 2011. The drive screw 2011 is inserted into the first screw hole. A drive motor 2013 is disposed at one end of the drive screw 2011, and the rotating shaft of the drive motor 2013 is connected to the drive screw 2011. The drive motor 2013 rotates the drive screw 2011, thereby moving the movable block 2022 and the cleaning strip 2021. Controlling the rotation direction of the drive screw 2011 adjusts the movement direction of the movable block 2022, thereby achieving a reciprocating wiping effect on the observation baffle 300.

[0031] In some possible embodiments, the test box 100 may be provided with multiple drive screws 2011, and the movable block 2022 may have a corresponding number of first screw holes, with the drive screws 2011 being inserted into each of the first screw holes. Each drive screw 2011 may be driven individually by a drive motor 2013, or by a transmission mechanism such as gears or a transmission belt. This allows a single drive motor 2013 to drive multiple drive screws 2011, thus reducing the cost of the drive motor 2013. The drive screws 2011 may be provided at both ends of the movable block 2022, with the multiple drive screws 2011 being parallel to each other. The multiple drive screws 2011 drive the two ends of the movable block 2022 to move synchronously, ensuring smooth movement of the movable block 2022 and preventing tilting or shaking of the movable block 2022.

[0032] Optionally, in some possible embodiments, a guide rod 2012 is provided on the test box 100 , the guide rod 2012 is parallel to the driving screw 2011 , a limiting hole is provided on the wiping mechanism 202 , and the guide rod 2012 is passed through the limiting hole.

[0033] Please refer to Figure 1 and Figure 2 As shown, the guide rod 2012 is parallel to the first screw, and the movable block 2022 has a limit hole defined therein, through which the guide rod 2012 is inserted. The guide rod 2012 limits the movable block 2022, ensuring that the movable block 2022 moves along a predetermined path and preventing the movable block 2022 from rotating and causing the cleaning strip 2021 to lose contact with the surface of the observation baffle 300. It should be noted that there may be multiple guide rods 2012, as long as all of them are parallel to the drive screw 2011.

[0034] Optionally, in some other embodiments, lubricant may be coated on the guide rod 2012 and the drive screw 2011 , and the friction between the moving block 2022 and the drive screw 2011 and the guide rod 2012 further improves the stability of the moving block 2022 during movement.

[0035] Optionally, in some possible embodiments, a clamping assembly 2023 is provided on the moving block 2022 , and the cleaning strip 2021 is detachably fixed to the clamping assembly 2023 .

[0036] Please refer to Figure 2As shown, in this embodiment, clamping blocks are provided on either side of the movable block 2022. Both clamping blocks are connected to the movable block 2022 via an elastic member. Under the elastic force of the elastic member, the clamping blocks tend to move toward each other, forming a clamping assembly 2023. The cleaning strip 2021 is clamped and fixed between the two clamping blocks, secured by the clamping blocks. Disassembling the cleaning strip 2021 requires only the use of external force to separate the two clamping blocks, making operation quick and easy, and the overall structure is simple and cost-effective. The elastic member can be an elastic device such as an elastic sheet or a coil spring.

[0037] Optionally, in some possible embodiments, a partition plate 400 is provided inside the test box 100 , and the partition plate 400 divides the interior of the test cavity into a plurality of independent test cavities.

[0038] Please refer to Figure 3 As shown, the partition plate 400 divides the interior of the test box 100 into multiple independent test cavities, so that multiple signal lamps to be tested can be placed, thereby improving test efficiency. It can be understood that in order to facilitate the placement of the signal lamp in the test box while also avoiding collision between the signal lamp and the interior of the placement cavity, the space of the placement cavity is usually larger, which is convenient for placing signal lamps of different shapes and sizes. During testing, the signal lamp is placed at the bottom of the placement cavity, which results in the space in the upper half of the placement cavity being wasted. At this time, a partition plate 400 is set in the placement cavity to separate the placement cavity into independent test cavities, thereby increasing the capacity of the placement cavity. During testing, multiple signal lamps can be placed in the placement cavity. Testing multiple signal lamps at the same time can not only improve test efficiency but also save energy.

[0039] Optionally, in some possible embodiments, the partition plate 400 is detachably connected to the test box 100. When multiple signal lamps need to be tested simultaneously, the partition plate 400 is installed. Conversely, when a larger signal lamp needs to be tested, the partition plate 400 is removed to avoid blocking the signal lamps to be tested.

[0040] Optionally, in some possible embodiments, an adjustment component 500 is provided on the test box 100 , the partition plate 400 is slidably provided in the test box 100 , and the partition plate 400 is driven to cooperate with the adjustment component 500 , and the adjustment component 500 is used to adjust the position of the partition plate 400 .

[0041] Please refer to Figure 3 As shown, a partition plate 400 is slidably mounted within the chamber. The partition plate 400 can slide vertically up and down to adjust the size of the test chambers. To simultaneously test signal lamps of different shapes or sizes, the position of the partition plate 400 can be adjusted to form test chambers of varying sizes, each housing a different signal lamp.

[0042] Optionally, in some possible embodiments, the inner side wall of the placing cavity is provided with a plurality of fixed slots or a plurality of fixed protrusions spaced apart in a vertical manner, and the partition plate 400 is clamped in any fixed slot or fixed protrusion. When the position of the partition plate 400 needs to be adjusted, the partition plate 400 is removed and clamped in the fixed slot or fixed protrusion at the corresponding height. The height adjustment of the partition plate 400 is realized by the structure of the fixed slot or fixed protrusion, which is simple in structure, low in cost, does not need to use other locking mechanisms, and is good in stability.

[0043] Optionally, in some other embodiments, the adjusting assembly 500 comprises an adjusting motor 501 and an adjusting screw 502, and the partition plate 400 is provided with a second screw hole, and the adjusting screw 502 is arranged in the second screw hole, and the adjusting motor 501 is drivingly connected with the adjusting screw 502.

[0044] Please refer to Figure 3 and Figure 4 , the adjusting assembly 500 adopts the same screw adjusting mechanism as the driving assembly, the adjusting screw 502 is arranged in the placing cavity in a vertical direction, and the adjusting screw 502 cooperates with the second screw hole on the partition plate 400. Under the driving of the adjusting motor 501, the clockwise or counterclockwise rotation of the adjusting screw 502 can realize the up-down movement of the partition plate 400. The position of the partition plate 400 is adjusted by the screw mechanism, which can realize stepless adjustment and move the partition plate 400 to any position. Meanwhile, the screw adjusting mechanism has self-locking property, can suspend the partition plate 400 at any position, and ensures the stability of the signal lamp after being placed.

[0045] Optionally, in some possible embodiments, the inner side wall of the test box 100 is provided with a sliding clamping groove 102, and the partition plate 400 is provided with a limiting protrusion 401 which is slidingly arranged in the sliding clamping groove 102.

[0046] The limiting protrusion 401 cooperates with the sliding clamping groove 102 to limit the movement of the partition plate 400 along the sliding clamping groove 102, so as to further improve the stability of the partition plate 400.

[0047] Optionally, in some possible embodiments, a movable sealing door 600 is arranged at the observation port 101, and when the sealing door 600 is opened, the observation port 101 can be used as a placing port of the placing cavity, so that the signal lamp to be tested is placed in the placing cavity. The transparent observation baffle 300 is arranged on the sealing door 600, and the observation port 101 is used as the placing port at the same time, so that a separate placing port does not need to be arranged, thereby reducing the sealing difficulty. When testing, only the observation port 101 needs to be sealed, so as to avoid the influence of cold air or hot air leakage on the accuracy of the test result.

[0048] It should be noted that the features of the embodiments in the present application can be combined with each other in the case of no conflict.

[0049] The above only is the preferred embodiment of the present application, and is not used to limit the present application, and the present application can have various changes and changes for the person skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
