[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] 1. This application provides an electric washing, sweeping, and mopping integrated vehicle, including a vehicle body. A water supply module, a sewage discharge module, and a rear suspension device are located at the rear of the vehicle body. The rear suspension device is driven by an electric lifting mechanism. The rear suspension device includes a washing and sweeping module, a squeegee module, and a mop module arranged sequentially front to back. The squeegee module and the sewage discharge module are connected via a first pipe. A front-drive motor is mounted on the front wheels of the vehicle body. The two rear wheels of the vehicle body are connected by two mating half-shaft structures, one of which is connected to the washing and sweeping module via a chain drive mechanism. This application has a simple structure, reasonable design, low investment cost, and diverse functions, achieving the effect of multi-purpose use. The front-mounted motor and front-wheel drive design eliminates the need for a rear axle gearbox, significantly reducing costs and freeing up ample space for rear suspension and other components. The rear axle uses a semi-shaft design, specifically two interlocking semi-shaft structures connecting the two rear wheels. This makes the vehicle more agile in cornering with a smaller turning radius. A chain drive mechanism (chain disc) is installed on the semi-shaft, which drives the rear wheels under front-wheel drive, while the rear wheels simultaneously drive the chain disc on the semi-shaft structure, driving the sweeping and cleaning module via chain transmission. This design eliminates the need for a dedicated motor for the sweeping / cleaning rollers, greatly saving costs. The rear-mounted suspension also increases lifting space and allows for the addition of multi-functional devices.

[0023] 2. This application also includes a water spray module, and the washing and sweeping module adopts a roller type, which enables the washing function when the water spray module is on and the sweeping function when the water spray module is off, making it convenient to use.

[0024] 3. The electric lifting mechanism of this application adopts segmented control to realize one-button control of dry mopping (oil mopping) and washing (sweeping) functions. Attached Figure Description

[0057] Preferably, such as Figures 6-9 As shown, it also includes a water spray module 5, and the water supply module 2 and the sweeping module 41 are connected through the water spray module 5;

[0058] The water spray module 5 includes a water pump 51 and a nozzle assembly 52. ​​The water pump 51 is located on the upper part of the half-shaft structure 10. The inlet of the water pump 51 is connected to the water supply module 2 through a second pipe 53, and a third pipe 54 is provided at the outlet. The end of the third pipe 54 is parallel to the cleaning roller 411, and the nozzle assembly 52 is provided on the third pipe 54 for spraying water onto the cleaning roller 411. A solenoid valve 55 is provided on the second pipe 53, and the nozzle assembly 52 has three nozzles that extend into the waterproof cover 412 to spray water onto the cleaning roller 411.

[0059] Preferably, the vehicle body 1 is equipped with a control main board, and the input terminals of the electric lifting mechanism 6, water supply module 2, sewage discharge module 3, washing and sweeping module 41, squeegee module 42, and mop module 43 are all connected to the output terminals of the control main board.

[0060] More preferably, such as Figure 16 As shown, it also includes a power switch 13, a lift switch 14 and a water spray switch 15 located on the front of the vehicle. The output terminals of the power switch 13, the lift switch 14 and the water spray switch 15 are all connected to the input terminals of the control main board.

[0061] The lifting switch 14 has two positions. When pressed once, the mop module 43 is activated. When pressed twice, the sweeping and washing module 41 is activated. When the water spray switch 15 is turned on, the washing mode is activated. When the water spray switch 15 is turned off, the sweeping mode is activated.

[0062] Preferably, such as Figure 12 , Figure 13 As shown, the electric lifting mechanism 6 is located at the rear of the vehicle body 1, and the telescopic end of the electric lifting mechanism 6 is connected to the middle position of the upper part of the fixed frame 413 (specifically the transverse connecting plate 4131) through the first connecting piece 47; the first connecting piece 47 has a through hole 471, and the end of the telescopic end of the electric lifting mechanism 6 is provided with a clamping groove. When the upper part of the first connecting piece 47 is inserted into the clamping groove, the telescopic end of the electric lifting mechanism 6 is fixedly connected to the first connecting piece 47 by passing a screw through the through hole 471.

[0063] like Figures 6-13As shown, the mop module 43 includes a mop connector 431, a mop 432, and a first return spring 45. One end of the mop connector 431 is connected to the first connecting piece 47, and the other end is connected to the mop 432. The mop connector 431 includes two vertical connecting pieces that are fixedly connected, and a second connecting piece 433 is provided between the two vertical connecting pieces and corresponding to the position close to the first connecting piece 47. The middle part of the mop connector 431 is a square frame, and the lower part of the first pipe 44 passes through the square frame. The lower part of the first return spring 45 is connected to the horizontal connecting plate 4131, and the upper part of the first return spring 45 is connected to the second connecting piece 433. The first return spring 45 can exert a certain downward pressure on the mop 432, so that the mop 432 is in contact with the ground.

[0064] like Figures 6-13 As shown, the wiper module 42 has a semi-circular structure, including a wiper strip 421 in the middle, two iron plates located inside and outside the wiper strip 421, rollers 422 at both ends of the two iron plates, and vertical iron pieces 423 connected to both ends of the iron plates. A slot 4134 for the iron pieces 423 to pass through is provided on the outer side of the first vertical connecting plate 4132. It also includes a second return spring 46, one end of which is connected to the outside of the slot 4134, and the other end is connected to the upper part of the iron piece 423. The wiper strip 421 is made of silicone. The second return spring 46 enables the wiper module 42 to fit in contact with the ground, effectively improving the wiping effect.

[0065] A fastener 424 is also connected to the iron plate 423 inside the wiper blade 421, such as... Figure 12 As shown, the first pipe 44 is fixed, and the end of the first pipe 44 is the suction port (water suction port or dust suction port) of the first pipe 44; after the wiper module 42 wipes away the water or debris cleaned by the sweeping module 41, the wiper module 42 collects the water or dust to the wiper strip 421, and the sewage discharge module 3 absorbs it through the first pipe 44.

[0066] Preferably, the sewage discharge module 3 is used to absorb and collect the water or debris scraped off by the squeegee module 42; the sewage discharge module 3 is a vacuum cleaner or a water suction device, or it can be a dual-purpose device that can both vacuum and suction water.

[0067] Preferably, the electric lifting mechanism 6 adopts segmented control to realize one-button control of dry mopping (oil mopping) and washing (sweeping) functions.

[0068] like Figure 14 , Figure 15As shown, it also includes a limit switch 11 disposed on the rear beam 105. One end of the limit switch 11 is located on the upper part of the second vertical connecting plate 4133, and the limit switch 11 is connected to the control main board. When the sweeping module 41 and the squeegee module 42 are not working, the limit switch 11 is above the second vertical connecting plate 4133. When the lifting switch 14 is turned on and the sweeping module 41 and the squeegee module 42 begin to descend, the limit switch 11 descends synchronously with the descent of the second vertical connecting plate 4133 and closes, and the water spray module 5 and the sewage discharge module 3 begin to work.

[0069] The usage method of the above embodiments specifically includes the following steps:

[0070] Step 1: Turn on the power switch 13 and press the lifting switch 14 to lower the rear suspension device 4 to the first position through the electric lifting mechanism 6. At this time, the mop module 43 touches the ground and starts to work. The first return spring 45 installed on this mop module 43 can better adhere to the ground by self-resetting, and dry mopping or oil mopping can be achieved by changing different mop cloths 432.

[0071] Step 2: Continue pressing the lifting switch 14 to lower the rear suspension device 4 to the second position. At this time, the sweeping module 41 and the squeegee module 42 touch the ground; at the same time, the limit switch 11 closes, and the water spray module 5 and the sewage discharge module 3 start to work.

[0072] Step 3: Using the separate water spray switch 15 installed on the water spray module 5, when the water spray switch 15 is turned on, the cleaning mode is entered; when the water spray switch 15 is turned off, the sweeping mode is entered.

[0073] Step 4: Turn the ignition switch and the vehicle will start moving. At this time, the front wheel 103 drives the rear wheel 104 to rotate. The rear wheel 104 will drive the chain drive mechanism 8 (chain disc) on the half-shaft structure 10 between the two rear wheels 104 to rotate. The chain disc will then drive the rear suspension device 4 to rotate, so that the sweeping (washing) work can be started while moving.

[0074] Step 5: During cleaning (washing), the waterproof cover 412 prevents water (dust) from splashing out, and then the water is collected by the squeegee module 42 and sucked away before reaching the inlet of the sewage discharge module 3. The remaining water is dried by the rear mop module 43.

[0075] In summary, this application has at least the following advantages:

[0076] 1. The motor is front-mounted and front-drive, eliminating the need for a rear axle gearbox configuration, which greatly reduces costs and leaves enough space for rear suspension and other devices;

[0077] 2. The rear axle adopts a half-shaft type, specifically, two mating half-shaft structures are used to connect the two rear wheels, making the vehicle more flexible in turning and with a smaller turning radius. The half-shaft is equipped with a chain drive mechanism (chain disc), which drives the rear wheels to rotate under the drive of the front wheels. At the same time, the rear wheels drive the chain disc on the half-shaft structure to rotate, which drives the sweeping module (sweeping / washing roller) to rotate through chain drive. This design eliminates the need to install a dedicated power motor for the washing / sweeping roller, greatly saving costs.

[0078] 3. The sweeping / washing module (sweeping / roller washing) adopts a roller type, which is different from the disc type device on the market. This device can realize the washing function when the water spray module is on and the sweeping function when the water spray module is off.

[0079] 4. The electric lifting mechanism adopts segmented control, realizing one-button control of dry mopping (oil mopping) and washing (sweeping) functions;

[0080] 5. It adopts a rear-mounted suspension device (rear-mounted suspension sweeping / washing system), which is different from the existing mid-mounted technology, and improves the lifting space and the possibility of adding multi-functional devices.

[0081] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0082] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
