Abstract
Description
Technical Field
[0001] This utility model relates to the field of RV interior structure technology, specifically to the field of RV interior structure technology composed of a gold frame. Background Technology
[0002] Existing technologies typically employ a design where the interior structure of a motorhome consists of four to six wooden panels, forming a simple wooden structure. The main technical aspects rely on self-tapping screws and corner brackets as the primary connection methods. This structure lacks strength and can easily cause secondary injuries to occupants under extreme conditions. Furthermore, this type of internal structure is prone to thermal expansion and contraction, resulting in unstable gaps between the connecting surfaces. This leads to significant noise over time. Additionally, the weight of four to six panels makes it heavy and detrimental to safe driving. Moreover, the inherent structural flaws result in low space utilization. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a motorhome interior structure composed of a metal frame, thereby solving the problems that the current interior structures of B-type and C-type motorhomes are not conducive to safe driving, and that the space utilization rate is also low due to the defects of the structure itself.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An interior structure of a motorhome with a metal frame includes a table frame and a cabinet frame that are bolted to one side of the interior of the vehicle. On the other side of the interior of the vehicle, a washroom frame, a side frame, and a bottom cabinet frame are bolted to one side of the interior of the vehicle. The cabinet frame is positioned opposite to the washroom frame. Pull-out bed board fixing supports are installed on the surfaces of the bottom cabinet frame and the side frame. A slide-out carriage is installed inside the pull-out bed board fixing supports.
[0006] As a preferred technical solution of this utility model, the countertop frame and cabinet frame, the washroom frame and side frame, and the side frame and base cabinet frame are all connected and fixed by welding.
[0007] As a preferred technical solution of this utility model, the top of the cabinet frame and the washroom frame are both provided with welded connecting plates, and the top of the welded connecting plates are connected to the interior top of the carriage by welding.
[0008] As a preferred embodiment of this utility model, a tabletop is welded to the top of the tabletop frame, a washing machine cabinet is installed on the side of the tabletop frame, and a groove is provided on the side of the tabletop at the position corresponding to the C-pillar of the carriage.
[0009] Compared with existing technologies, the beneficial effects of this utility model are: First, it is safer. The entire internal structure of the RV is composed of square steel frames or aluminum alloy square profiles, which are stronger than the original wooden board structure, thus providing greater safety in extreme conditions. Second, the lightweight internal skeleton structure can be used to assemble the various furniture and modular structures inside the RV with minimal material usage, making it lighter than the old structure. Third, the connection methods include welding, riveting, screw fastening, and structural adhesive bonding. Different connection methods are used in different locations to improve overall strength and durability. The advantages of the new product can be summarized as follows: improved safety, reduced overall noise, increased space utilization, enhanced durability, and extended service life.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3 This utility model provides a technical solution:
[0016] A motorhome interior structure consisting of a metal frame is described. First, on one side of the interior of the vehicle, the tabletop frame 1 is fixed in a suitable position with bolts. Then, the cabinet frame 2 is fixed to one side of the tabletop frame 1 with bolts. On the other side of the interior of the vehicle, the washroom frame 3, side frame 5, and bottom cabinet frame 4 are fixed in sequence with bolts to ensure that the cabinet frame 2 and the washroom frame 3 are positioned opposite each other.
[0017] Then, welding operations are performed between the countertop frame 1 and cabinet frame 2, the washroom frame 3 and side frame 5, and the side frame 5 and base cabinet frame 4 to make the connection of each frame more stable. At the same time, welding connection plates 11 are installed on the top of cabinet frame 2 and washroom frame 3, and the top of welding connection plates 11 is connected to the top of the interior of the carriage by welding, which enhances the connection strength between the entire frame structure and the carriage. In addition, the frames on the surfaces opposite to the interior walls of the carriage are also welded to the interior walls of the carriage, thereby greatly improving the overall sturdiness.
[0018] Next, the tabletop 9 is welded to the top of the tabletop frame 1, the washing machine cabinet 10 is installed on the side of the tabletop frame 1, and a groove 12 is made on the side of the tabletop 9 at the position corresponding to the C-pillar of the carriage. Finally, a pull-out bed board fixing support 6 is installed on the surface of the bottom cabinet frame 4 and the side frame 5, and a slide 7 that can slide out is installed inside the pull-out bed board fixing support 6.
[0019] In actual use, when a rest is needed, the slide 7 can be slid out from the pull-out bed board fixing support 6, and a bed board can be laid on the slide 7 to form a sleeping space; the tabletop 9 can be used for washing, placing items and other operations; the washing machine cabinet 10 can be used to install a washing machine to realize the washing function; the setting of the recess 12 can make reasonable use of the space near the C pillar of the carriage and further improve the space utilization rate.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
