DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0018] like Figure 1 As shown, the electric sanitation vehicle chassis uses a layer frame structure, which is fixedly installed on the body chassis 1 of the electric sanitation vehicle, and is used to install and fix various functional components of the electric sanitation vehicle during cleaning operations, so that their layout is more reasonable and they occupy less plane space of the body chassis 1, thereby helping to further miniaturize the sanitation vehicle. Specifically, it includes a low-level bracket 2, and a high-level bracket 3 is fixedly connected to one side of the low-level bracket 2. The low-level bracket 2 and the high-level bracket 3 form an integrated connection structure to facilitate synchronous installation and fixation, and the arrangement is quick. There is no need to adjust the position between the two, and the installation speed is fast. The chassis connecting frame 4 is respectively arranged and installed on the low-level bracket 2 and the high-level bracket 3. The connection between the low-level bracket 2, the high-level bracket 3 and the body chassis 1 is realized through the chassis connecting frame 4, and the number of settings can be flexibly adjusted. An overhead space 5 is formed between the lower bracket 2, the higher bracket 3 and the top surface of the vehicle chassis 1, respectively, for realizing the utilization of the space below the two brackets, so that the functional components of the electric sanitation vehicle are arranged in upper and lower layers, thereby reducing the overall length of the vehicle body.

[0019] Specifically, the lower bracket 2 includes at least four lower bracket legs 21, and the top end of each lower bracket leg 21 is fixedly connected to the bracket top frame 22. The lower bracket legs 21 and the bracket top frame 22 are hollow as a whole, which is conducive to the lightweight design of the vehicle body. The lower bracket legs 21 can be made of square tubes, and the bracket top frame 22 is made of angle steel, which has high support strength and good load-bearing capacity. The chassis connecting frame 4 is configured as an L-shaped angle plate, and some of the lower bracket legs 21 can be selected to be connected to the chassis connecting frame 4 to achieve connection with the vehicle chassis 1. The chassis connecting frame 4 can be connected to the lower bracket legs 21 by welding, and can be detachably connected to the vehicle chassis 1 by the cooperation of bolts and nuts, which is simple to disassemble and assemble, and convenient to maintain.

[0020] The high-rise support 3 includes an elevated support leg 31 which is linearly and fixedly installed on the support top frame 22. A high-rise support leg 32 used in conjunction with the elevated support leg 31 is provided on the side away from the low-rise support 2. The elevated support leg 31 and the top of the high-rise support leg 32 are connected and supported with a support top plate 33. The cooperation between the elevated support leg 31 and the support top frame 22 reduces the use size of some components of the high-rise support 3. The high-rise support leg 32 is arranged opposite to part of the low-rise support leg 21. Connecting cross beams 34 are respectively provided between the high-rise support leg 32 and the relative low-rise support leg 21, and between part of the elevated support leg 31 and the high-rise support leg 32. After being connected, the entire shelf structure can be stable and firm. The elevated support leg 31 and the high-rise support leg 32 are also arranged as square tube structures, and the connecting cross beam 34 is arranged as angle steel.

[0021] Part of the chassis connecting frame 4 is arranged on the connecting crossbeam 34 between the lower bracket leg 21 and the higher bracket leg 32. By using reasonable components of the chassis connecting frame 4 of this embodiment, the number of components used can be reduced, which helps to improve assembly efficiency and reduce the use of parts and lightweight design. Based on the layout design of various functional components on the electric sanitation vehicle made using this embodiment, the lower bracket 2 is arranged on the inner side of the higher bracket 3 on the vehicle chassis 1 to facilitate the use and storage of functional components.

[0022] like Figure 1 and Figure 2 As shown, the utility model also discloses an electric sanitation vehicle using the layered structure for the chassis of the electric sanitation vehicle, including a vehicle chassis 1, an electric driving device 6 is installed at the top of the vehicle chassis 1, and a cleaning device 7 is installed at the bottom of the vehicle chassis 1.

The electric driving device 6 includes a steering wheel, a brake pedal and other structures. The cleaning device 7 includes a garbage bin, a cleaning disc, a water spray nozzle and other structures arranged at the bottom of the vehicle chassis 1. The electric driving device 6 and the cleaning device 7 are both well known to ordinary technicians in the technical field and will not be described in detail here.

[0023] The chassis structure of the electric sanitation vehicle is fixedly mounted on the vehicle chassis 1, and the main water tank 8 and the electrical control box 9 are fixedly mounted on the lower bracket 2. Specifically, a fixed baffle 10 made of angle steel is provided in the bracket top frame 22 to fix the main water tank 8 and make its installation more secure. The electrical control box 9 is used for power distribution and safety control of the motor, water pump, etc. on the vehicle.

[0024] A drive axle transmission wheel 11 is fixedly installed in the overhead space 5, and the drive axle transmission wheel 11 is connected to the drive axle of the electric sanitation vehicle through a chain drive. The above-mentioned position setting of the drive axle transmission wheel 11 enables the electric sanitation vehicle to form a mid-mounted chain transmission structure, so that the garbage bin arranged at the bottom of the vehicle chassis 1 can be better avoided, making the overall design of the electric sanitation vehicle more reasonable.

[0025] The high-rise support 3 is fixedly mounted with a hose reel 12, a high-pressure water pump 13 and a motor driver 14. The hose reel 12 is required to reel or unwind the pipe, and is installed on the rear side of the vehicle body for easy operation. The motor driver 14 can be installed and fixed on the connecting crossbeam 34 between the elevated support leg 31 and the high-rise support leg 32. A high-pressure fan 15 is fixedly mounted at the rear end of the high-rise support 3 to generate negative pressure to collect garbage into the garbage bin.

[0026] The utility model uses a layered structure on the chassis of the electric sanitation vehicle to centralize and install the functional components of the electric sanitation vehicle in layers, saving a large space in the front for the cab and its functional configuration, and improving the comfort of the whole vehicle operation. The utility model has a simple structure, is beautiful in appearance, and is easy to install and disassemble.
