[0043] like Figure 1 and Figure 2As shown, the rain test device includes a gantry 1, a top spray rack 2, a side spray rack 3 and an end spray rack 4, wherein the gantry 1 can move back and forth along the first direction (X direction) across the experimental object; the top spray rack 2 is movably arranged above the gantry 1, and the moving direction of the top spray rack 2 is along the vertical direction (Z direction), and the top spray rack 2 is used to spray the top of the experimental object; there are multiple side spray racks 3, and multiple side spray racks 3 can be movably arranged below the gantry 1, and the side spray racks 3 are used to spray both sides of the experimental object; there are at least two end spray racks 4, and at least two end spray racks 4 are spaced apart along the second direction (Y direction) and the spacing is adjustable. The end spray racks 4 are used to spray both ends of the experimental object, and the first direction and the second direction are perpendicular to each other and both perpendicular to the vertical direction.

[0044] The rain test device provided by the present invention is provided with a gantry 1 that moves along a first direction, so that the gantry 1 can be appropriately moved according to the position of the experimental object so that the top spray frame 2 can be directly above the experimental object. The top spray frame 2 that can move along the vertical direction can adjust the spray distance according to the height of the experimental object. The movable side spray frame 3 can adjust the spray distance according to the position of both sides of the experimental object, and the end spray frame 4 with adjustable distance can adjust the spray distance according to the position of both ends of the experimental object. The above constitutes a rain test device with adjustable spray distance, which solves the problem that rain test devices for small and medium-sized vehicles and large vehicles cannot be universal, greatly increases the scope of application, improves the utilization rate of the rain test device, greatly reduces the experimental cost, and greatly reduces the occupied area in the non-experimental state, with high resource utilization.

[0045] For ease of explanation, in this embodiment, three top spray racks 2 are spaced apart along the second direction (Y direction) above the gantry 1. Two end spray racks 4 are spaced apart along the second direction at both ends of the gantry 1. Three side spray racks 3 are provided on both sides of the gantry 1 along the first direction. Of course, since the side spray racks 3 are movable, the number of side spray racks 3 and top spray racks 2 used can be selected according to the size of the experimental object during the experiment. The gantry 1 has a length (along the Y direction) of no less than 17m, a width of no less than 3.5m, and a height of no less than 6.5m, so as to be suitable for a wide range of experimental objects.

[0046] In some embodiments, the rain test device further includes a guide rail 5 , and the gantry 1 is slidably connected to the guide rail 5 .

[0047] like Figure 2As shown, in this embodiment, the two guide rails 5 extend along the first direction, and the gantry 1 is slidably connected to the two guide rails 5, and can then slide along the guide rails 5 to achieve reciprocating movement of the gantry 1 in the first direction, so as to adjust its position according to the position of the experimental object, so that the top spray frame 2 can spray directly above the experimental object.

[0048] In some embodiments, the rain test device further includes a first driving mechanism 6 , which is configured to drive the gantry 1 to move on the guide rail 5 .

[0049] like Figure 2 In this embodiment, the guide rail 5 is an electric guide rail, and the first drive mechanism 6 is disposed below the gantry 1 to drive the gantry 1 to move on the guide rail 5. Preferably, the first drive mechanism 6 is provided on each of the two guide rails 5. When the gantry 1 moves, the two first drive mechanisms 6 are synchronously activated to drive the gantry 1 to move, thereby providing sufficient driving force and ensuring smooth and safe movement of the gantry 1.

[0050] In some embodiments, the bottom end of the side spray rack 3 is provided with a plurality of first universal wheels (not shown) for movement. The provision of the first universal wheels allows the side spray rack 3 to be freely moved, allowing manual movement of the side spray rack 3 to a desired position. This facilitates flexible adjustment of the position and number of side spray racks 3 according to the location of the experimental object, thereby improving the flexible configuration capability of the spray experiment device and enhancing its applicability.

[0051] In some embodiments, among the multiple end spray racks 4, at least one end spray rack 4 is fixed on the gantry 1 to move synchronously with the gantry 1, and the bottom end of at least one end spray rack 4 is provided with multiple second universal wheels for movement.

[0052] In this embodiment, two end spray racks 4 are provided as an example. Figure 1 The end spray rack 4 shown on the right end is fixedly mounted on the gantry 1 and can be moved and adjusted synchronously with the gantry 1. The end spray rack 4 on the left end can be freely moved and adjusted by means of multiple second universal wheels (not shown in the figure), so as to facilitate adjustment of the spacing between the two end spray racks 4, thereby achieving adjustment of the spray position according to the end position of the experimental object, improving the flexible configuration of the spray test device, greatly improving versatility, and achieving good spray test results. More conveniently, the end spray rack 4 with second universal wheels can also be used interchangeably with the side spray rack 3.

[0053] In some embodiments, a plurality of top spray racks 2 are provided, and the plurality of top spray racks 2 are spaced apart along the first direction.

[0054] like Figure 1As shown, three top spray racks 2 are provided along the second direction, and each top spray rack 2 can be individually controlled to spray, so that the required number of top spray racks 2 can be selectively opened according to the size of the experimental object along the second direction, thereby saving energy.

[0055] In some embodiments, the top spray frame 2 includes a second driving mechanism 21, a top frame 22 and a top water pipe 23, wherein the second driving mechanism 21 is arranged on the gantry 1; the top frame 22 is slidably connected to the gantry 1, and the top frame 22 is connected to the output end of the second driving mechanism 21 for lifting and lowering movement; the top water pipe 23 is fixed on the top frame 22, and a plurality of top nozzles 24 are arranged at intervals on the top water pipe 23.

[0056] Combine Figure 2 and Figure 3 As shown, the top frame 22 can move up and down in the vertical direction (Z direction) so as to adjust the spray distance according to the height of the experimental object. In this embodiment, the second drive mechanism 21 is an electric drive mechanism (such as a motor), which is controlled by a radio handle. The output end of the second drive mechanism 21 is provided with a reducer to connect the top frame 22 so as to control the lifting speed of the top frame 22. The multiple top nozzles 24 arranged at intervals on the top water pipe 23 are arranged in accordance with the standards of the spraying requirements, which are not limited in this embodiment. Similarly, the nozzles on the side spray rack 3 and the end spray rack 4 are also arranged in accordance with the standards of the spraying requirements, which will not be further described in this embodiment.

[0057] In some embodiments, the top spray frame 2 also includes a screw 25 and a connecting rod assembly 26. The bottom end of the screw 25 is movably connected to the top frame 22. The top end of the screw 25 passes through the gantry 1 and is rotatably connected to the gantry 1 through a worm gear 27. When the screw 25 rotates, it can drive the lifting movement of the top frame 22; one end of the connecting rod assembly 26 is connected to the output end of the second drive mechanism 21, and the other end of the connecting rod assembly 26 is provided with a worm 28, which is connected to the worm gear 27 for transmission. When the second drive mechanism 21 drives the connecting rod assembly 26 to rotate, the worm 28 drives the worm gear 27 to rotate and then drives the screw 25 to rotate.

[0058] like Figure 2As shown, the bottom end of the screw 25 is connected to the top frame 22 via a bearing, so that the screw 25 can rotate relative to the top frame 22. At the same time, when the screw 25 rotates and rises relative to the gantry 1, it can drive the top frame 22 to move up and down. The gantry 1 is rotatably connected to a worm gear 27. The worm gear 27 has an internal thread that matches the thread of the screw 25. The worm gear 27 has an external gear that matches the worm 28 for transmission connection. When the output end of the second drive mechanism 21 drives the connecting rod assembly 26 to rotate, it drives the worm 28 to rotate. The screw 25 is driven to rotate through the transmission connection between the worm 28 and the worm gear 27, and finally the lifting and lowering drive control of the top frame 22 is achieved. In this embodiment, a second driving mechanism 21 and four screw rods 25 are arranged at intervals on the top frame 22, and the connecting rod assembly 26 includes six connecting rods, two of which are connected to the output end of the second driving mechanism 21 through a reducer, and the other ends of the two connecting rods are respectively connected to two connecting rods provided with a worm 28 through a reducer to realize rotational transmission output, thereby realizing rotational drive of the four screw rods 25, so that the lifting and lowering movement of the top frame 22 is stable and reliable.

[0059] In some embodiments, the rain test device further includes a base 7 , on which the guide rails 5 , the side spray racks 3 and at least part of the end spray racks 4 are arranged, and the base 7 is provided with a drainage groove 71 .

[0060] like Figure 2 As shown, the base 7 provides a stable platform for the movable side spray racks 3 and end spray racks 4. Drainage troughs 71 are provided on the base 7 to facilitate the collection and treatment of spray water, thereby achieving resource recycling. The number and arrangement of drainage troughs 71 may be one or more depending on the specific situation.

[0061] In some embodiments, the rain test device further includes a water tank (not shown in the figure), on which a plurality of hoses are provided, which are respectively connected to the top spray rack 2, the side spray rack 3 and the end spray rack 4 to provide spray water.

[0062] Specifically, a water tank is also mounted on the base 7. This placement of the water tank reduces the length of hoses required between the water tank and each of the top spray racks 2, side spray racks 3, and end spray racks 4, saving material costs. Water from the drain trough 71 on the base 7 is collected and filtered before being re-injected into the water tank for recycling. The top spray racks 2, side spray racks 3, and end spray racks 4 are each connected to the water tank via hoses, facilitating individual control of the water supply to each of the three spray racks, as well as facilitating mobility.

[0063] 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.
