Which is better between the splicing structure body and the integrated FRP body of the RV?
As far as the manufacturing and use experience of RV is concerned, European and American countries and our neighbor Japan have a long history of RV development. At present, China's RV market is also in the stage of rapid development, and the market capacity is increasing day by day, especially the demand for self-propelled C-type RV is increasing greatly.
At the same time, due to the lack of awareness, many consumers are not clear about their actual use needs. They blindly focus on power, configuration and space, but ignore a series of practical pain points such as warmth preservation, silence and structural strength during the use of RV.
So the question is, in the current self-propelled C-type RV, how to choose between the domestic mainstream sandwich splicing structure body and the minority FRP integrated body, and what are the advantages and disadvantages of each?
Almost 95% of the self-propelled C-type RV in China adopts sandwich splicing structure. The reason is very simple and the advantages are obvious. First, the process is low, and the whole carriage can be formed by connecting all the body surfaces with rivets. Second, the splicing process does not need to develop molds, which greatly reduces the production cost and significantly improves the single vehicle profit. Third, the splicing process is relatively flexible, And support space expansion.
In particular, the feature of supporting space expansion meets the high demand of domestic RV consumers for the use space of the compartment living area. Therefore, expandable RV has become the absolute main model in the self-propelled C-type RV segment market, and has an absolute advantage in both the number of models and the actual sales.
However, most of the outdoor users who have some experience in the use of RV have more determined to choose the one-piece casting RV when purchasing the RV for the second time. After all, there are some pain points in the use of RV, which can only be realized based on certain experience. In their words, some past experiences are the tuition fees that must be paid in their RV career, and with the improvement of experience in the use and outdoor, they can better understand, What is the real need to buy an RV
Compared with sandwich spliced body, the integrated body needs to go through at least four stages of R & D from design to mold opening, from production to verification, so as to successfully realize mass production and listing. The mold development cost alone often accounts for a considerable part of the profit space of manufacturers
The benefits are also obvious. The integrally formed FRP body does not need any rivet splicing and is cast as a whole, so that the body has absolute tightness and structural strength. The keel is embedded inside the shell to strengthen the structural strength, while the FRP itself has the characteristics of high strength and high toughness, especially in line with the requirements of RV for the body shell.
Due to the excellent sealing performance, the internal polyurethane and other filling materials are basically isolated from the outside world. Therefore, the internal filling materials will not be affected by moisture or deterioration, and the cold resistance and thermal insulation performance will not change in long-term use. At the same time, there is no need to worry about the breeding of toxic odor gases due to dampness and mildew.
In addition to having extremely high protection, the integrated FRP body has extremely high structural strength. In case of serious collision accident or accidental rollover, there will be no risk of disintegration due to the overall stress of the body, and the impact resistance is stronger. At the same time, during the driving for many years, there will be no small structural deformation of the body caused by the driving impact. After a period of use, the abnormal noise of driving becomes more and more serious, and the driving noise becomes louder. When spending the night outdoors, the thermal insulation performance of the car body also decreases significantly. In addition, the carriage is filled with musty smell and peculiar smell for a long time, and the source of the peculiar smell can not be found, which is quite a headache.
The occurrence of these problems is directly related to the slight deformation of the carriage structure, coupled with the poor waterproof performance of the spliced body. After the rain enters the interior of the car shell through the deformed splice, the filler in the car shell will be damp, deteriorated or even moldy. Most importantly, these problems will exist with the use for life without any solution.
Although the RV with splicing process body can provide congenital conditions for space expansion, the above problems will gradually appear with the service life, and the integrated RV can fundamentally avoid the above problems. As for the space utilization rate, it can be improved through design optimization.
Based on the integrated FRP body, Fuji RV also has a streamlined body appearance, flat truck chassis, which can also maximize the living space. The internal design perfectly inherits the advantages of Japanese RV in space utilization. Not only the layout of each functional area is clear and reasonable, but also the storage space is rich, and the water and electricity configuration is also perfect and complete.
