Switching between cleaning modes (such as sweeping, vacuuming, and high-pressure washing) requires either installation on the sides or bottom of the chassis, or manual removal and reinstallation of the different devices. The former increases vehicle weight and vulnerability, while the latter is time-consuming and requires specialized tools for disassembly and reassembly. Furthermore, existing new energy washing and sweeping vehicles utilize a customized connection between the power system and the cleaning device, resulting in poor compatibility and difficulty adapting to diverse scenarios. Therefore, a modular, quick-change solution is needed to enable plug-and-play cleaning devices and meet the efficient energy management requirements of new energy vehicles. Summary of the Invention

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] like Figure 1-8As shown, a modular new energy washing and sweeping vehicle includes a vehicle chassis 100, such as Figure 1 As shown, the chassis 100 of the new energy sweeper and washer is shown.

[0046] Base 500, such as Figure 1 、 4 -8, there are multiple ones installed on the vehicle chassis 100, and the base 500 is integrated with an electrical interface A501, a cleaning water interface A502, a hydraulic oil inlet A503, and a hydraulic oil return port A504. The electrical interface A501, the cleaning water interface A502, the hydraulic oil inlet A503, and the hydraulic oil return port A504 are all female ends of quick connectors with pull sleeves and steel balls. A movable plate 507 is provided in the base 500, and the movable plate 507 is connected to the pull sleeves of multiple interfaces and is driven to move by a driving mechanism 508. The driving mechanism 508 drives the movable plate 507 to move, thereby driving all the pull sleeves to move backward. After the interface connection is completed, the movable plate 507 is reset and the pull sleeve is reset forward to form a lock. The base 500 is provided with multiple pin holes 505 and a locking device 506 located on the side of the pin hole 505 to lock the positioning pin 605 in the pin hole 505.

[0047] Cleaning modules, each of which is provided with a substrate 600 for pairing with the base 500, one or more cleaning modules are mounted on the base 500 via the substrate 600, such as Figure 1-3 As shown, in actual application, the cleaning module includes one or more of a washing and sweeping device 200, a high-pressure washing device 300, and a dust collecting device 400, which can be selected or used in combination as needed.

[0048] like Figure 4 As shown in FIG. 7 , a plurality of positioning pins 605 are provided on the base plate 600, and the positioning pins 605 can be inserted into the pin holes 505 of the base 500. The positioning pins 605 are provided with locking grooves 6051 for cooperating with the locking device 506 for locking. The base plate 600 is integrated with one or more of the electrical interface B601, the cleaning water interface B602, the hydraulic oil inlet B603, and the hydraulic oil return port B604. The electrical interface B601, the cleaning water interface B602, the hydraulic oil inlet B603, and the hydraulic oil return port B604 are respectively the male ends of the quick connectors matched with the electrical interface A501, the cleaning water interface A502, the hydraulic oil inlet A503, and the hydraulic oil return port A504.

[0049] During installation, the substrate 600 and the base 500 of the cleaning module are paired, the positioning pin 605 is inserted into the pin hole 505, and is locked by the locking device 506. The interfaces are paired and connected. During the process, the driving mechanism 508 drives the movable plate 507 to move, thereby driving all the pull sleeves to move backward. The electrical interface B601, the cleaning water interface B602, the hydraulic oil inlet B603, and the hydraulic oil return port B604 are respectively inserted into the electrical interface B601, the cleaning water interface A502, the hydraulic oil inlet A503, and the hydraulic oil return port A504. After the interface connection is completed, the movable plate 507 is driven to reset, and the pull sleeve is reset forward to form a lock.

[0050] In practical applications, such as Figure 5 As shown in / 8, the locking device 506 includes a sleeve 5061, a locking pin 5062, a spring 5063, and a guide rod 5064. A guide groove is provided in the base 500. The direction of the guide groove is perpendicular to the direction of the pin hole 505, and the guide groove and the pin hole 505 are connected. The sleeve 5061 is fixedly installed on the base 500, and a locking pin 5062 is slidably provided in the sleeve 5061. The locking pin 5062 extends into the guide groove. The spring 5063 is provided in the sleeve. 5061, and the end surface of the locking pin 5062 abuts against each other. The locking pin 5062 and the latch are provided with a matching locking structure. The side of the locking pin 5062 is provided with an inclined hole. The guide rod 5064 is slidably connected to the inclined hole. The guide rod 5064 is fixed to the movable plate 507. When the movable plate 507 moves, it drives the guide rod 5064 to move. The inclined guide rod 5064 drives the locking pin 5062 to slide relative to the sleeve 5061, achieving the switching between the locked and unlocked states. Moreover, the movement of the movable plate 507 itself is used to control the connection and disconnection of the electrical, oil, and water circuits. The guide rod 5064 is fixed to the movable plate 507, so only a single drive mechanism 508 is required to achieve the locking of the latch, electrical, oil, and water circuits.

[0051] In practical applications, such as Figure 8 As shown, the locking pin 5062 and the latch pin are provided with a matching tooth-shaped locking structure, and the tooth-shaped locking structure includes multiple planes and multiple conical surfaces.

[0052] In practical applications, such as Figure 5As shown in Figure 7, a synchronous lifting mechanism 509 is provided between the movable plate 507 and the base 500. The synchronous lifting mechanism 509 includes a slide rail 5091 and a telescopic frame 5092. There are four slide rails 5091, two of which are fixed on the movable plate 507, and the other two are fixed on the base 500. The telescopic frame 5092 is fork-shaped and connects four shafts 5093, two of which are fixed to the slide rails 5091, and the other two slide in the slide rails 5091, thereby ensuring that the movable plate 507 remains stable during movement.

[0053] In practical applications, such as Figure 5 As shown, a rectangular through hole 510 is provided on the side of the base 500, and a pressing portion 5071 is provided on the movable plate 507. The pressing portion 5071 extends out of the base 500 through the rectangular through hole 510. Manual force can be applied to the pressing portion 5071 to achieve the movement of the movable plate 507, thereby controlling the connection and disconnection of electrical, oil and water circuits.

[0054] In practical applications, such as Figure 7 As shown, the driving mechanism 508 is a cylinder installed on the back of the base 500 , and the telescopic end of the driving mechanism 508 is connected to the movable plate 507 .

[0055] Another aspect of the present invention provides a control system for a modular new energy washing and sweeping vehicle, such as Figure 9 As shown, it includes a touch screen, an intelligent control module, a hydraulic power source, a power supply, and a water source. The hydraulic power source is connected to the hydraulic oil inlet A503 and the hydraulic oil return port A504 respectively, the water source is connected to the cleaning water interface A502, and the power supply is connected to the electrical interface A501. The intelligent control module is used to control the output status of the hydraulic power source, water source, and power supply, and the touch screen is used for manual control.

[0056] In actual application, a module identification unit is provided in the base 500, and a module identification mark is provided on the substrate 600, which can identify which cleaning module is connected, separate different device types, and call preset operating parameters (such as hydraulic pressure, water pump flow, electrical parameters), which is more intelligent.

[0057] In actual application, the module identification unit is a code scanning device, and the module identification mark is provided with different QR codes according to the type of cleaning module. Based on the QR code scanning, the type of installed cleaning device is automatically identified.

[0058] How this solution works:

[0059] The present invention designs a new set of standardized bases 500 and base plates 600. The base 500 is installed on the chassis, and the base plates 600 are installed on different cleaning modules. According to the work requirements, a suitable cleaning module can be selected, and the base 500 and the base plate 600 cooperate to achieve quick installation. In addition, since the base 500 integrates the electrical interface A501, the cleaning water interface A502, the hydraulic oil inlet A503, and the hydraulic oil return port A504, the base plate 600 integrates one or more of the electrical interface B601, the cleaning water interface B602, the hydraulic oil inlet B603, and the hydraulic oil return port B604 according to the different modules. The position of the pull sleeve on the interface is controlled by the movable plate 507 and the driving mechanism 508 to control the connection and disconnection of the electrical, oil and water circuits. At the same time, a locking mechanism is used to lock the pin on the base plate 600 to achieve quick fixation of the cleaning module.

[0060] In summary, the modular new energy washing and sweeping vehicle and its control system described in the present invention realize the rapid replacement of cleaning devices (such as sweeping brush modules, dust collection modules and high-pressure flushing modules, etc.) through standardized interfaces, intelligent locking and adaptive control systems, thereby reducing operation and maintenance costs and improving operational flexibility.
