[0023] Please refer to the appendix Figure 2 and the appendix Figure 8 - appendix Figure 9, inside the side cabin 3, a water source utilization mechanism 8 is provided. The water source utilization mechanism 8 includes a placement cabin 810. A placement cabin 810 is opened on the side cabin 3. An extraction pump 801 is arranged inside the placement cabin 810. The input end of the extraction pump 801 is connected to an extraction head 805 through a water pipe. The output end of the extraction pump 801 is connected to a filtration component through a water pipe. The filtration component is connected to a storage water tank 806 through a water pipe. Inside the storage water tank 806, a heating component is provided. The placement cabin 810 is used to stably place and protect other key components of the water source utilization mechanism 8. The function of the extraction pump 801 is to provide power for the entire water utilization system, extracting water from an external water source or other storage containers to subsequent treatment processes. The extraction head 805 is usually designed with a structure with a filtration grid, and the grid aperture size is appropriate, which can prevent larger particulate impurities and foreign objects from entering the water pipe and blocking the extraction pump 801. The storage water tank 806 is a container for storing purified water resources; The filtration component includes a filtration box 802. The filtration box 802 is arranged between the output end of the extraction pump 801 and the storage water tank 806 and is connected by a water pipe. Inside the filtration box 802, an activated carbon filtration layer 803 and a quartz sand filtration layer 804 are provided. The filtration box 802 houses and supports filtration media such as the activated carbon filtration layer 803 and the quartz sand filtration layer 804, providing a stable filtration space and environment for the water purification process. The activated carbon filtration layer 803 can effectively remove impurities such as organic matter, residual chlorine, and odor in water through physical adsorption and chemical adsorption. The quartz sand filtration layer 804 can filter out suspended particles, colloids, and other impurities in water; The heating component includes a heat preservation layer 807 and a circular heating wire 808. Inside the storage water tank 806, the heat preservation layer 807 and the circular heating wire 808 are sequentially arranged from the outside to the inside. A water temperature sensor 809 is arranged inside the storage water tank 806. The function of the heat preservation layer 807 is to reduce the heat exchange between the hot water inside the storage water tank 806 and the external environment, reduce the heat dissipation speed, enable the hot water to maintain within a suitable temperature range for a long time, save energy consumption, and meet the continuous demand for hot water by campers for a period of time. The circular heating wire 808 heats and disinfects the water in the storage water tank 806. The water temperature sensor 809 feeds back the water temperature information to the control system in real time. The control system controls the heating state of the circular heating wire 808 according to the set temperature threshold. For example, when the water temperature is lower than the set temperature, the circular heating wire 808 is started for heating; when the water temperature reaches or is higher than the set temperature, the heating is stopped, thereby realizing precise control of the water temperature inside the storage water tank 806, meeting the different demands of campers for the hot water temperature, and at the same time avoiding energy waste and the inconvenience caused by too high or too low water temperature.

[0024] Please refer to the appendix Figure 1 - appendix Figure 4, a charging component 9 is provided on the top of the vehicle body 1, and a control button 10 is provided on the side cabin 3. The charging component 9 includes a fixing frame 901 which is arranged on the top of the vehicle body 1. A solar charging panel 902 is arranged on the fixing frame 901. A storage battery 903 is arranged inside the vehicle body 1. The storage battery 903 and the solar charging panel 902 are connected by a wire. The main function of the fixing frame 901 is to provide a stable and reliable installation platform for the solar charging panel 902. The solar charging panel 902 can effectively convert the received solar energy into electrical energy, and the storage battery 903 is a key component for storing electrical energy.

[0025] Working principle: After the vehicle body 1 travels to the designated position, the control button 10 is pressed. The control button 10 enables the storage battery 903 to supply power to the hydraulic push rod 201. The hydraulic push rod 201 pushes the auxiliary cabin 202 outwards, and the auxiliary cabins 202 of the side cabin 3 and the rear cabin 4 extend outwards, increasing the internal space of the vehicle body 1. When the hydraulic push rod 201 reaches the designated value when it is pushed out, the locking motor 507 is started. The locking motor 507 rotates the worm gear 504. The rotating worm gear 504 makes the slider 506 slide on the slide rod 505 through the meshing relationship with the worm 503. The blocking block 502 on the slider 506 moves along with it, and the blocking block 502 slides into the blocking groove 508 on the auxiliary cabin 202 to fix the auxiliary cabin 202. When it rains or the sunlight is too strong, the mounting block 604 is slid into the mounting post 601. During the sliding process, when the blocking key 605 touches the blocking cap 603, the blocking key 605 is retracted into the mounting block 604. At this time, the compression fixing spring 607 is compressed. When the mounting block 604 slides to the middle section of the mounting post 601, the fixing spring 607 releases its elastic potential energy, and the blocking key 605 pops out to fix the shielding mechanism 7 connected by the connecting shaft 608 and the mounting plate 609. The fixing rod 711 on the fixing block 710 is rotated, and then the drawing rod 702 is pulled. The shielding cloth 708 is pulled out along with the drawing rod 702 and is fixed by hanging it into the hanging ring 709 through the hook 712. The shielding cloth 708 provides shade and shelter for the camping personnel. When the reserve water is insufficient, the extraction head 805 is pulled out, and through the extraction pump 801, the external water is pumped towards the filter box 802 and is filtered successively by the activated carbon filter layer 803 and the quartz sand filter layer 804. The treated water enters the storage water tank 806. When the water temperature sensor 809 senses that the temperature is lower than the designated value, then the storage battery 903 supplies power to the circular heating wire 808. The energized circular heating wire 808 generates heat to boil and disinfect the water in the storage water tank 806. The heat preservation layer 807 keeps the water warm. The disinfected water can be used. The solar charging panel 902 can convert solar energy into electrical energy to charge the storage battery 903. After the camping is over, the control button 10 is pressed again, and the locking motor 507 rotates in reverse to slide the blocking block 502 out of the blocking groove 508 along with the slider 506. The hydraulic push rod 201 retracts to take the auxiliary cabin 202 into the vehicle body 1. After the hanging ring 709 is removed from the hook 712, the winding motor 705 in the installation cabin 704 is started. Through the meshing relationship of the gear one 706 and the gear two 707, the winding shaft rotates. After the winding shaft rotates, the shielding cloth 708 is wound up. Using the length of the connecting shaft 608, the placing rod 701 is moved left and right. By driving the sliding key 602 to slide into the blocking cap 603, the mounting block 604 can be removed from the mounting post 601.
