[0026] The following is combined with Figures 1-4 This invention describes an assembled protective cover for the safety indicator light at the rear of an engineering vehicle.

[0027] In one embodiment, an assembled protective cover for a safety indicator light at the rear of an engineering vehicle includes: a mounting indicator box 1, with an indicator flashing light 2 fixedly connected to the inner wall of the mounting indicator box 1, and multiple positioning holes 11 provided at both ends of the mounting indicator box 1; a cleaning mechanism 3, which is installed inside the mounting indicator box 1, and the surface of the cleaning mechanism 3 extends to the outer side of the mounting indicator box 1; wherein the cleaning mechanism 3 includes an assembly component 31 installed at the end of the mounting indicator box 1, the surface of the assembly component 31 extending to the side of the mounting indicator box 1 near the indicator flashing light 2, and a cleaning component 32 connected to the surface of the assembly component 31, the surface of the cleaning component 32 extending to the inner bottom wall of the mounting indicator box 1;

[0028] like Figure 1-4 As shown, the assembly component 31 includes two connecting plates 311 disposed at the ends of the mounting indicator box 1. A first rivet 315 is disposed inside the connecting plate 311. The end of the first rivet 315 passes through the positioning hole 11 and extends into the interior of the mounting indicator box 1. A connecting bracket 312 is fixedly connected to the side of the connecting plate 311 near the indicator flashing light 2. Two cleaning strips 313 are fixedly connected between the two connecting brackets 312. The surface of the cleaning strip 313 contacts the surface of the cleaning component 32. A sliding rail 314 is fixedly connected to the surface of the connecting plate 311 away from the mounting indicator box 1. The surface of the sliding rail 314 contacts the surface of the cleaning component 32. Side grooves 316 are provided on both sides of the sliding rail 314. The side grooves 316 are at the same horizontal height as the adjacent first rivet 315.

[0029] In this embodiment, the device, through the assembly component 31, can be quickly assembled with the installation indicator box 1. The first rivet 315 passes through the connecting plate 311 and enters the interior of the installation indicator box 1 through the positioning hole 11. The first rivet 315 can be threaded to cooperate with the positioning hole 11, and the specific configuration can be adjusted according to actual usage requirements. The two connecting brackets 312 can provide auxiliary guidance for the transparent plate 322, and the cleaning strip 313 can assist in cleaning the transparent plate 322, ensuring a good transparent display effect of the transparent plate 322, reducing external environmental impurities, and shielding the transparent plate 322 to ensure a good indication function. The side groove 316 facilitates the installation and connection operation of the first rivet 315 by the operator.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning component 32 includes two electric push rods 326 fixedly connected to the bottom wall of the mounting indicator box 1. The telescopic ends of the electric push rods 326 extend through to the top of the mounting indicator box 1 and are fixedly connected to a top plate 321. A transparent plate 322 is fixedly connected to one side of the top plate 321. The surface of the transparent plate 322 away from the indicator flashing light 2 contacts the surface of the cleaning strip 313. A sliding strip 323 is connected to the lower end of the top plate 321 near the positioning hole 11. A second rivet 325 is threaded to the upper end of the sliding strip 323. A groove 324 is opened on one side of the sliding strip 323. The lower end of the second rivet 325 extends into the interior of the groove 324.

[0031] In this embodiment, the top plate 321 is driven by the electric push rod 326 to move longitudinally, and the top plate 321 drives the transparent plate 322 to move up and down. The second rivet 325 can drive the sliding bar 323 to move longitudinally synchronously. When the transparent plate 322 moves up, the lower cleaning bar 313 cleans the surface of the transparent plate 322. The opening of the slide groove 324 allows the sliding bar 323 to move longitudinally and be guided along the surface of the sliding rail 314.

[0032] Working principle: The set assembly component 31 quickly forms a splicing installation with the installation indicator box 1. The first rivet 315 passes through the connecting plate 311 and enters the interior of the installation indicator box 1 through the positioning hole 11. The two connecting brackets 312 assist in guiding the transparent plate 322. Under the action of the cleaning strip 313, the transparent plate 322 is cleaned to ensure a good transparent display effect of the transparent plate 322 and reduce the obstruction of the transparent plate 322 by external environmental impurities. The top plate 321 is driven by the electric push rod 326 to move longitudinally. The top plate 321 drives the transparent plate 322 to move up and down. The setting of the second rivet 325 drives the sliding strip 323 to move longitudinally synchronously. When the transparent plate 322 moves up, the lower cleaning strip 313 cleans the surface of the transparent plate 322. The opening of the slide groove 324 allows the sliding strip 323 to move longitudinally along the surface of the sliding rail 314.

[0033] It should be noted that the indicator flashing light 2 and the electric push rod 326 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to the actual needs. At the same time, the indicator flashing light 2 and the electric push rod 326 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
