Description

Technical Field

[0001] This utility model relates to the technical field of vehicle body connectors, specifically to a bottom-side connection structure for a recreational vehicle body. Background Technology

[0002] In the current manufacturing process of motorhome bodies, as users' demands for lightweight, modular, and maintainable designs continue to rise, traditional body structure connection methods are gradually revealing numerous shortcomings. On the one hand, conventional welding or screw-based direct connection methods result in complex structures and cumbersome processes, leading to increased overall weight and hindering the energy efficiency and driving efficiency of motorhomes. On the other hand, inconvenient disassembly and assembly, and high maintenance difficulty, significantly increase the cost of later maintenance and replacement. Furthermore, some body structures have exposed fasteners at connection points, which not only affect the aesthetics but also pose safety hazards such as impacts or loosening, making it difficult to meet the dual requirements of aesthetics and safety for modern motorhomes.

[0003] Especially in the connection structure between the bottom plate and the side plate, traditional structures are mostly achieved by combining multiple independent components, resulting in low connection accuracy, unstable positioning, and easy to cause gap deviation or structural shaking, affecting the overall strength and sealing of the carriage.

[0004] In view of the above, this application proposes a bottom-side connection structure for a recreational vehicle body to solve the above problems. It has functions such as self-positioning, quick assembly, and embedded fastening, which improves the overall assembly efficiency while also taking into account the aesthetic appearance, the convenience of disassembly and maintenance, and the stability and reliability of the connection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bottom-side connection structure for a recreational vehicle body, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bottom-side connection structure for a recreational vehicle body includes a main body, which is integrally formed by extruding aluminum. A first mounting groove is provided on one side of the main body, into which a base plate is inserted. A second mounting groove and a third mounting groove are symmetrically arranged on the other side of the main body. A side upper plate is inserted in the second mounting groove, and a side lower plate is inserted in the third mounting groove. The side upper plate and the side lower plate are arranged along a horizontal line. The base plate is perpendicularly spliced ​​with the side upper plate and the side lower plate. A sliding groove is provided on the side of the main body corresponding to the side lower plate, into which a nut is inserted. The nut, in conjunction with a screw, secures the side lower plate to the main body. An I-beam is provided on the side of the main body away from the first mounting groove, and the I-beam is connected and installed with external expansion equipment.

[0008] Optionally, the body includes a vertical plate, a horizontal plate, and a connecting rod; there are two horizontal plates, which are symmetrically arranged on the left side of the vertical plate, and the connecting rod is arranged on the right side of the vertical plate.

[0009] Optionally, the connection gap between the two transverse plates forms the first mounting groove.

[0010] Optionally, the upper and lower sides of the connecting rod cooperate with the vertical plate and the I-beam to form the second mounting groove and the third mounting groove.

[0011] Optionally, the contact surfaces of the body with the bottom plate, the upper side plate, and the lower side plate are all provided with semi-circular shafts.

[0012] This utility model provides a bottom-side connection structure for a motorhome body, which has the following advantages:

[0013] 1. This utility model provides a bottom-side connection structure for a recreational vehicle body. Through the multi-groove mating structure between the main body and the bottom plate, upper side plate, and lower side plate, efficient and rapid assembly and precise positioning are achieved. The plates are fixed by screws through slot fitting, which ensures connection strength and improves overall stability. The use of a sliding groove and nut embedded structure eliminates the need for exposed fasteners during screw fixing, which not only improves the overall appearance and aesthetics but also effectively reduces the risk of external impacts and loosening. The semi-circular shaft structure set on each contact surface significantly reduces assembly friction, improves assembly smoothness, and reduces surface wear, which helps to extend the service life of the structure.

Therefore, they should not be construed as limitations on this utility model.

[0019] This application proposes a bottom-side connection structure for a recreational vehicle body, as detailed below:

[0020] For reference Figure 1-2 This application mainly consists of a body 1, a first mounting groove 2, a base plate 3, a second mounting groove 4, a third mounting groove 5, an upper side plate 6, a lower side plate 7, a sliding groove 8, and an I-beam shaft 9, which are arranged together to enable the base plate and side plate to be quickly assembled and firmly positioned after connection. The structure is stable and reliable, easy to maintain and expand, and suitable for the lightweight, modular and standardized manufacturing needs of motorhome bodies. It has the advantages of light weight, high strength, convenient assembly, and beautiful and practical appearance.

[0021] For reference Figure 1-2 The main body 1 of this application is integrally formed by extrusion of aluminum metal, including a vertical plate 11, a horizontal plate 12, and a connecting rod 13; there are two horizontal plates 12, which are symmetrically arranged on the left side of the vertical plate 11, and the connecting rod 13 is arranged on the right side of the vertical plate 11; the connection gap between the two horizontal plates 12 forms a first mounting groove 2, and a base plate 3 is inserted into the first mounting groove 2 and fixed together by screws; the upper and lower sides of the connecting rod 13 cooperate with the vertical plate 11 and the I-beam 9 to form a second mounting groove 4 and a third mounting groove 5, respectively; a side upper plate 6 is inserted into the second mounting groove 4, and when the side upper plate 6 is inserted, nothing is installed in the third mounting groove 5. At this point, connecting and fixing the upper side plate 6 with screws is relatively convenient. A lower side plate 7 is inserted into the third mounting slot 5. After installation, the connecting surface of the lower side plate 7 is obscured. Therefore, a sliding groove 8 is further provided on the side of the main body 1 corresponding to the lower side plate 7. A screw is inserted through a hole drilled in the lower side plate 7. In use, a nut is inserted into the sliding groove 8, causing the screw to engage with the nut in the groove 8. After tightening the screw, the lower side plate 7 is firmly fixed to the third mounting slot 5 of the main body 1. With this structure, there are no protruding fasteners on the outside, resulting in a more aesthetically pleasing appearance. Furthermore, while the upper side plate 6 and the lower side plate 7 are arranged along a horizontal line, they are also separate, making the structure clear and facilitating individual disassembly, repair, or replacement of damaged parts, reducing later maintenance costs.

[0022] For reference Figure 1-2 The contact surfaces of the main body 1 with the base plate 3, the upper side plate 6 and the lower side plate 7 are all provided with semi-circular shafts 10. The semi-circular shafts 10 can reduce the friction between the base plate 3, the upper side plate 6 and the lower side plate 7 and the surface of the main body 1 when they are inserted. At the same time, the semi-circular shafts 10 can also relatively avoid friction between the screw side and the main body 1 when connected by screws.

[0023] In this invention, the working steps of the device are as follows:

[0024] First, insert the base plate 3 into the first mounting groove 2 formed by the two horizontal plates 12 of the body 1. The frictional resistance is reduced by the semi-circular shaft 10 structure between the base plate 3 and the body 1, so that the base plate 3 can slide smoothly into the designated position. Then, fix it with screws to ensure its stability.

[0025] Next, the upper side plate 6 is inserted into the second mounting groove 4 formed between the vertical plate 11 and the connecting rod 13, and fixed with screws. Since the third mounting groove 5 is still empty at this time, there is enough operating space, which is conducive to quick positioning and connection.

[0026] Next, insert the lower side plate 7 into the third mounting slot 5. The mounting position of the lower side plate 7 is located below the structure and the connecting surface is the shielding surface. Therefore, by using the sliding groove 8 pre-set in the main body 1 to cooperate with the drilled part of the lower side plate 7, after inserting the nut, the screw is inserted from the outside and bites into the nut in the sliding groove 8. After tightening, a firm fixation is achieved, while maintaining a clean appearance with no exposed screws, thus improving the overall aesthetics.

[0027] In addition, semi-circular shafts 10 are provided between the bottom plate 3, the upper side plate 6, and the lower side plate 7 and the main body 1. While achieving stable engagement, these shafts further reduce assembly friction, making it easier to disassemble, repair, or replace the vehicle later. This effectively reduces maintenance costs and meets the assembly requirements for lightweight and modular design of the motorhome body.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model.
