[0024] Figure 1 It is a top view of the RV chassis provided in some embodiments of the present application.

[0025] See also Figure 1 In a first aspect, the present application provides a motorhome chassis 10, comprising a frame 100, a power battery 200 and a water tank assembly 300, wherein the frame 100 comprises a front frame 110, a middle frame 120 and a rear frame 130; the power battery 200 is arranged in the middle frame 120; the water tank assembly 300 is used to contain domestic water, and the water tank assembly 300 is arranged in the middle frame 120 and is arranged side by side with the power battery 200.

[0026] Specifically, the front frame 110, the middle frame 120 and the rear frame 130 are distributed along the length direction of the RV chassis 10, the front frame 110 is arranged near the front end of the RV chassis 10, the rear frame 130 is arranged near the rear end of the RV chassis 10, and the middle frame 120 is located between the front frame 110 and the rear frame 130, and respectively connects the front frame 110 and the rear frame 130. It can be understood that in the RV chassis 10, the power battery 200 is used as the power source of the whole vehicle, and the water tank assembly 300 is used to hold domestic water. The weight of the two accounts for a large proportion of the overall weight of the RV chassis 10. Therefore, in the present application, the power battery 200 and the water tank assembly 300 are arranged in the middle frame 120, so that the center of gravity of the RV chassis 10 can be brought closer to the center of the chassis, which can improve the stability and safety of the RV chassis 10. It should be noted that the water tank assembly 300 is used to contain domestic water, which may include clean water to be used and / or used waste water, which is not limited in this embodiment.

[0027] The present application provides a motorhome chassis 10, including a frame 100, a power battery 200 and a water tank assembly 300. The frame 100 includes a front frame 110, a middle frame 120 and a rear frame 130. The water tank assembly 300 is used to contain domestic water. It is arranged side by side with the power battery 200 on the middle frame 120, which can avoid occupying the space of the front frame 110 and the rear frame 130, so that the structure of the motorhome chassis 10 is more compact, thereby improving the space utilization of the motorhome chassis 10.

[0028] Figure 2 It is an axonometric view of the RV chassis provided in some embodiments of the present application.

[0029] See also Figure 2 In some embodiments, the middle section frame 120 includes a frame 100 body, and the frame 100 body includes two longitudinal beams 121 spaced apart along the width direction of the RV chassis 10 and two cross beams 122 spaced apart along the length direction of the RV chassis 10. The cross beam 122 is located between the two longitudinal beams 121 and is respectively connected to the two longitudinal beams 121. The two longitudinal beams 121 and the two cross beams 122 jointly define a accommodating space 123. At least part of the power battery 200 is located in the accommodating space 123 and is connected to at least one of the longitudinal beams 121 and the cross beams 122.

[0030] In these embodiments, the two longitudinal beams 121 are spaced apart along the width direction of the RV chassis 10, and each longitudinal beam 121 can extend approximately along the length direction of the RV chassis 10. The two cross beams 122 are spaced apart along the length direction of the RV chassis 10, and each cross beam 122 can extend approximately along the width direction of the RV chassis 10. The two cross beams 122 are located between the two longitudinal beams 121, and the two ends of each cross beam 122 can be connected to the two longitudinal beams 121, so that the two cross beams 122 and the two longitudinal beams 121 can be connected. The accommodating space 123 is enclosed and at least part of the power battery 200 is located in the accommodating space 123. Compared with suspending the power battery 200 under the middle frame 120, the ground clearance of the power battery 200 can be increased to improve the safety performance. Alternatively, when the ground clearance of the power battery 200 is constant, the height of the RV chassis 10 can be lowered, so that the size of the passenger compartment located above the middle frame 120 along the height direction of the RV chassis 10 is increased, thereby improving the comfort of the vehicle.

[0031] It should be noted that when at least part of the power battery 200 is located in the accommodating space 123, the two cross beams 122 can be respectively located on both sides of the power battery 200 along the length direction of the RV chassis 10, and the two longitudinal beams 121 can be respectively located on both sides of the power battery 200 along the width direction of the RV chassis 10. At this time, the power battery 200 can be connected to at least one of the two cross beams 122 and the two longitudinal beams 121.

[0032] In some optional embodiments, the power battery 200 may include a battery module and a battery box. The battery box may include a top wall and a bottom wall. The top wall and the bottom wall are respectively connected to two cross beams 122 and two longitudinal beams 121. The top wall, the bottom wall, the two cross beams 122 and the two longitudinal beams 121 may be together enclosed to form a space for accommodating the battery module, thereby eliminating the need to set side walls in the battery box. The volume of the power battery 200 can be reduced while ensuring the battery life of the battery module, and the space occupied by the power battery 200 in the middle section of the frame 120 can be reduced. Alternatively, the space for accommodating the battery module can be increased to enhance the battery life of the power battery 200.

[0033] Please continue reading Figure 1 and Figure 2 In some embodiments, the middle section frame 120 includes a frame 100 body and a first partition beam 124 arranged on the frame 100 body, the frame 100 body defines a accommodating space 123, the accommodating space 123 is divided into a first area 125 and a second area 126 by the first partition beam 124, the power battery 200 is arranged in the first area 125, the water tank assembly 300 is arranged in the second area 126, and the power battery 200 and / or the water tank assembly 300 are connected to the first partition beam 124.

[0034] Specifically, the body of the frame 100 includes two longitudinal beams 121 spaced apart along the width direction of the RV chassis 10 and two transverse beams 122 spaced apart along the length direction of the RV chassis 10, so as to define a receiving space 123 by the two transverse beams 122 and the two longitudinal beams 121. The two ends of the first partition beam 124 can be respectively connected to the two transverse beams 122 or respectively connected to the two longitudinal beams 121. When the two ends of the first partition beam 124 are respectively connected to the two transverse beams 122, the first partition beam 124 divides the receiving space 123 into a first area 125 and a second area 126 distributed along the width direction of the RV chassis 10. When the two ends of the first partition beam 124 are respectively connected to the two longitudinal beams 121, the first partition beam 124 divides the receiving space 123 into a first area 125 and a second area 126 distributed along the length direction of the RV chassis 10. When the power battery 200 is disposed in the first area 125 and the water tank assembly 300 is disposed in the second area 126, the power battery 200 and the water tank assembly 300 may be connected to the cross beam 122 and / or the longitudinal beam 121. At the same time, the power battery 200 and / or the water tank assembly 300 may be further connected to the first partition beam 124, thereby improving the stability of the power battery 200 and / or the water tank assembly 300.

[0035] Figure 3 A top view of a mid-section frame provided for some embodiments of the present application.

[0036] See also Figure 3 In some embodiments, the water tank assembly 300 is connected to the first dividing beam 124, and the water tank assembly 300 includes a first water tank 310 for containing clean water and a second water tank 320 for containing waste water. The first water tank 310 and the second water tank 320 are arranged side by side along the length direction of the first dividing beam 124, and the first water tank 310 and / or the second water tank 320 are connected to the first dividing beam 124.

[0037] In these embodiments, among the power battery 200 and the water tank assembly 300, at least the water tank assembly 300 is connected to the first partition beam 124, and the water tank assembly 300 includes a first water tank 310 for containing clean water and a second water tank 320 for containing waste water, which can facilitate the use of water by passengers, and at the same time can prevent waste water from polluting the environment, thereby improving the practicality of the RV chassis 10. The first water tank 310 and the second water tank 320 are arranged side by side along the length direction of the first partition beam 124, so that the first water tank 310 and / or the second water tank 320 can be connected to the first partition beam 124, thereby improving the stability of the first water tank 310 and / or the second water tank 320.

[0038] It should be noted that, in the present embodiment, the first water tank 310 and / or the second water tank 320 may also be connected to at least one of the cross beam 122 and the longitudinal beam 121 to ensure that the first water tank 310 and / or the second water tank 320 are stably assembled.

[0039] Please continue reading Figure 3 In some embodiments, the middle section frame 120 further includes a second partition beam 127, which is respectively connected to the frame 100 body and the first partition beam 124, and the second area 126 is divided into a first sub-area and a second sub-area by the second partition beam 127, the first water tank 310 is located in the first sub-area, the second water tank 320 is located in the second sub-area, and the first water tank 310 and / or the second water tank 320 are connected to the second partition beam 127.

[0040] In these embodiments, the second partition beam 127 is connected to the vehicle frame 100 body and the first partition beam 124 respectively. When the first partition beam 124 is connected to two cross beams 122 to separate the accommodation space 123, the two ends of the second partition beam 127 can be connected to the first partition beam 124 and one longitudinal beam 121 respectively. When the first partition beam 124 is connected to two longitudinal beams 121 to separate the accommodation space 123, the two ends of the second partition beam 127 can be connected to the first partition beam 124 and one cross beam 122 respectively. The second area 126 is divided into a first sub-area and a second sub-area by the second partition beam 127. The first sub-area and the second sub-area are distributed along the length direction of the first partition beam 124. By arranging the first water tank 310 in the first sub-area and the second water tank 320 in the second sub-area, the first water tank 310 and / or the second water tank 320 are further connected to the second partition beam 127, thereby further improving the stability of the first water tank 310 and / or the second water tank 320.

[0041] In some embodiments, the first partition beam 124 and / or the second partition beam 127 are respectively detachably connected to the frame 100 body, so that various areas of the middle section frame 120 can be reasonably adjusted according to actual needs, thereby improving the application range of the RV chassis 10.

[0042] For example, by disassembling and adjusting the position of the first partition beam 124, the sizes of the first area 125 and the second area 126 can be adjusted, so that the first area 125 can be used to accommodate a power battery 200 of a corresponding capacity, and the second area 126 can be used to accommodate a corresponding water tank assembly 300. For example, when the vehicle has a large capacity demand for the power battery 200, the size of the first area 125 can be increased and the size of the second area 126 can be reduced, so that the RV chassis 10 can be equipped with a power battery 200 of a larger capacity.

[0043] In some embodiments, the first area 125 and the second area 126 are distributed along the length direction of the RV chassis 10, the first area 125 is arranged close to the front frame 110, and the second area 126 is arranged close to the rear frame 130, so that the power battery 200 and the water tank assembly 300 are distributed in sequence along the length direction of the RV chassis 10, and the power battery 200 is arranged close to the front frame 110, and the water tank assembly 300 is arranged close to the rear frame 130, so that by reasonably setting the positions of the power battery 200 and the water tank assembly 300, the space utilization of the RV chassis 10 is more reasonable, and the weight distribution of the RV chassis 10 is more uniform, thereby reducing the risk of overturning of the RV chassis 10 and improving safety performance.

[0044] It should be noted that the first area 125 and the second area 126 are distributed along the length direction of the RV chassis 10 , and the two ends of the first partition beam 124 are respectively connected to the two longitudinal beams 121 , and are spaced apart from the two cross beams 122 along the length direction of the RV chassis 10 .

[0045] Figure 4 It is a top view of the RV chassis provided in some embodiments of the present application.

[0046] See also Figure 4 In some embodiments, the RV chassis 10 also includes a thermal management module, which is disposed on the front frame 110 and is at least used for heat exchange with the power battery 200; and / or, the RV chassis 10 also includes an extended-range module 400, which is disposed on the rear frame 130 and connected to the power battery 200.

[0047] The thermal management module may include a radiator, a compressor and a heat pump, which are connected via heat exchange pipes, and part of the heat exchange pipes may also extend to the power battery 200 and exchange heat with the power battery 200. In these embodiments, the thermal management module is located at the front frame 110, which can facilitate heat exchange with the power battery 200.

[0048] The range-extending module 400 is used to supply power to the vehicle drive system or to charge the power battery 200, and the RV chassis 10 is the chassis of the range-extending hybrid vehicle. The range-extending module 400 may include a range extender 410, a fuel tank 420, an air intake unit 430 and an exhaust unit 440. The range extender 410 may include an engine, a generator and a generator controller. The range-extending module 400 is electrically connected to the power battery 200. During the operation of the range-extending module 400, the power battery 200 may first supply power to the generator, so that the generator runs and drives the engine to start, thereby supplying power to the vehicle drive system or charging the power battery 200 through the engine. The range-extending module 400 includes an air intake unit 430, which may be connected to the air intake of the engine to deliver air to the inside of the engine. The exhaust unit 440 is connected to the exhaust port of the engine, which may discharge the exhaust gas generated during the operation of the engine. It is understood that in the vehicle, the exhaust pipe of the exhaust unit 440 usually extends to the rear end of the vehicle and exhausts at the rear end of the vehicle. Therefore, in this embodiment, the range extender module 400 is integrated in the rear frame 130, so that the exhaust pipe of the exhaust unit 440 can directly exhaust to the external environment at the rear frame 130 without extending from other areas of the RV chassis 10 to the rear frame 130 for exhaust. This can shorten the length of the exhaust pipe in the exhaust unit 440, reduce the volume of the range extender module 400 and its space occupation on the RV chassis 10.

[0049] It should be noted that in these embodiments, the thermal management module is arranged on the front frame 110, the power battery 200 and the water tank assembly 300 are arranged on the middle frame 120, and the range extender module 400 is arranged on the rear frame 130, which can make the weight distribution of the RV chassis 10 as uniform as possible, thereby improving the safety performance of the vehicle.

[0050] A second aspect of the present application provides a vehicle comprising the RV chassis 10 of any one of the above items.

[0051] In some embodiments, the vehicle also includes a floor arranged on the RV chassis 10, the power battery 200 includes a battery box and a battery module, the battery box includes a bottom plate and side panels arranged around the circumference of the bottom plate, the bottom plate and the floor are arranged opposite to each other, the side panels are connected to the floor, the floor, the side panels and the bottom plate are combined to form a accommodating cavity, the battery module is arranged in the accommodating cavity, so that there is no need to set a top cover in the battery box, and the volume of the power battery 200 can be reduced while ensuring the battery life of the battery module, and the space occupied by the power battery 200 in the middle section frame 120 can be reduced, or the space used to accommodate the battery module can be increased, so that the battery life of the power battery 200 is enhanced.

[0052] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here.
