[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and 2 This utility model provides a technical solution: a frame structure for a four-wheeled cleaning vehicle, comprising two identical main beams 1, which are parallel and L-shaped. A front beam 3 is fixed to the end of each main beam 1. An upper frame 2 is connected to the main beam 1 via support columns 11. A tail beam 14 is connected to the rear of the upper frame 2, enhancing its rigidity and reducing deformation. A flat plate is attached to the surface of the upper frame 2 to form the cleaning vehicle's cargo bed, which holds a water tank and pump. The width of the upper frame 2 is greater than the distance between the two main beams 1. A vertical positioning post 12 is fixed to the other end of the upper frame 2. The positioning post 12 divides the upper frame 2 into two areas, front and back. The front area is used to place the battery. By setting the main beam 1 and the positioning post 12, the space inside the upper frame 2 is partitioned by the positioning post 12, which expands the battery installation space and meets the installation space requirements of large batteries. The battery is installed below the upper frame 2, which staggers the battery and other components vertically to avoid collisions between the battery and other components and improves safety. At the same time, the main beam 1 can provide support for the battery and enhance the rigidity and strength of the vehicle body.

[0024] like Figure 3 As shown, a filter mounting plate 21 is fixed on the side of the upper frame 2. The filter mounting plate 21 is used to install a filter to filter the water in the water tank and prevent impurities in the water from entering the water pipe and clogging it.

[0025] A crossbeam 13 is fixed inside the upper frame 2. The crossbeam 13 is connected to the rear end face of the positioning column 12. The crossbeam 13 enhances the rigidity of the upper frame 2 and also connects the positioning column 12 together to position the installation position of the positioning column 12.

[0026] Corner posts 15 are welded to the lower ends of the two front corners of the upper frame 2. A connecting beam 18 connects the corner posts 15 and the support posts 11. Side posts 17 are also connected to the lower surface of the upper frame 2. External beams 4 are connected to the sides of the side posts 17 and the corner posts 15. The external beams 4 are distributed on both sides of the upper frame 2. By welding the external beams 4, the corner posts 15 and the side posts 17 are positioned to ensure that they are on the same straight line. At the same time, a foot pedal 6 is fixed on the external beam 4 to facilitate the driver's foot placement.

[0027] A bottom beam 16 is connected between the side columns 17. The bottom beam 16 is located on the bottom surface of the main beam 1. The bottom beam 16 enhances the rigidity of the upper frame 2 and also connects the main beam 1 together, positioning the main beam 1 and ensuring the distance between the two.

[0028] A canopy 7 is connected between the upper end of the upper frame 2 and the upper end of the front beam 3. The canopy 7 includes a rear canopy 72 fixed on the upper frame 2 and a front canopy 71 installed on the front beam 3. The front canopy 71 is connected by two bent tubes. The lower end of each bent tube is connected to a mounting plate. By rotating the fasteners, the mounting plate and the front canopy 71 are fixed to the upper frame 2. The lower end of the rear canopy 72 is also connected to a mounting plate. The mounting plate is connected to the front beam 3 by fasteners. Both the front canopy 71 and the rear canopy 72 are formed by bending tubes and are sleeved together.

[0029] A backrest 73 is connected to one side of the rear canopy 72, which provides back support for the driver.

[0030] like Figure 2 As shown, a downwardly inclined mounting beam 51 is fixed on the side of the front beam 3. The lower end of the mounting beam 51 is connected to the anti-collision beam 5. A reinforcing rib 52 is also connected between the mounting beam 51 and the main beam 1. The reinforcing rib 52 enhances the rigidity of the anti-collision beam 5 and the connection strength between the anti-collision beam 5 and the mounting beam 51.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
