Description

Technical Field

[0001] This utility model relates to the technical field of panel connection components, specifically to an arc transition connection structure for recreational vehicles. Background Technology

[0002] As people's quality of outdoor leisure life improves, recreational vehicles (RVs), as multifunctional transportation tools integrating living, travel, and lifestyle, are gradually becoming an important carrier in the leisure tourism field. In the structural design of RVs, the vehicle body, as the main load-bearing and protection unit, directly affects the safety and service life of the entire vehicle due to its structural stability, strength, and assembly efficiency. Traditional vehicle bodies mostly adopt a planar connection structure, that is, the side panels and the roof panels are spliced ​​together with simple angle irons, screws, or welded components. This not only has limited structural strength, but also easily causes cracking and loosening due to uneven stress or environmental influences during long-term use, thus reducing the overall performance of the RV.

[0003] While some existing technologies use curved connectors made from aluminum profiles, most have simple structural designs, low connection strength, and cannot meet the needs of various plate thicknesses and different connection angles. Furthermore, most do not consider the buffering of connection deviations caused by assembly errors, resulting in problems such as complex installation, unstable structure, and difficult maintenance in practical applications.

[0004] In view of the above, this application proposes an arc transition connection structure for motorhomes to solve the technical problems of poor structural adaptability, low connection strength and insufficient functional integration in the prior art, and improve the overall structural performance of the motorhome body. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a circular arc transition connection structure for recreational vehicles, which solves the problems mentioned in the background section.

The end of the B-axis away from the A-axis is connected to the C-axis along an arc. The side of the C-axis away from the B-axis is shaped to fit one end of the side panel. The B-axis includes a connecting rod, a reinforcing beam, a first herringbone beam, and a second herringbone beam. The two ends of the connecting rod are connected to the A-axis and the C-axis.

One end of the second herringbone beam is connected to the C-axis, and the other end is connected to the surface of the reinforcing beam. An installation groove is formed in the middle of the connection between the first herringbone beam and the second herringbone beam.

[0007] Optionally, the A-axis includes a connecting plate, a short plate, and an arc plate; The short plate is perpendicular to the connecting plate, and the length of the connecting plate in the left region of the short plate is the same as the length of the short plate. One end of the arc plate is connected to the top of the short plate, and the other end is connected to the right side of the connecting plate.

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

[0015] This application proposes an arc transition connection structure for a recreational vehicle, the details of which are as follows: For reference Figure 1-2 This application is mainly composed of a main body 1 and side panels 2 and a top panel 3 connected on both sides of the main body 1. The relative movement between the structures makes the structure lightweight, while the connection between the structures provides a certain support force, which can effectively reduce the occurrence of breakage. It is also conducive to the connection between the side panels 2 and the top panel 3, suitable for panels of different thicknesses, and has good fixed connection strength, which brings great convenience to the design of motorhome bodies.

[0016] For reference Figure 1-2 The main body 1 is arc-shaped and located in the middle of the connection between the side panel 2 and the top panel 3. The main body 1 includes an A-axis 11, a B-axis 12 and a C-axis 13. One side of the A-axis 11 is shaped to fit the surface of the top panel 3, and the other side is connected to the B-axis 12 along the arc. The end of the B-axis 12 away from the A-axis 11 is connected to the C-axis 13 along the arc. The side of the C-axis 13 away from the B-axis 12 is shaped to fit one end of the side panel 2.

[0017] For reference Figure 1-2Furthermore, A-axis 11 includes a connecting plate 111, a short plate 112, and an arc plate 113. The short plate 112 is perpendicular to the connecting plate 111, and the length of the connecting plate 111 in the left area of ​​the short plate 112 is the same as the length of the short plate 112. One end of the arc plate 113 is connected to the top of the short plate 112, and the other end is connected to the right side of the connecting plate 111. Through this connection arrangement, the deformation between the structures is reduced after the connection. However, because A-axis 11 is located at the top support connection, it forms an arc connection with B-axis 12 downwards, which increases the force between A-axis 11 and the top plate 3. Under long-term use, the short plate 112 will deform, resulting in anomalies at its connection point and causing it to no longer fit the top plate 3 during installation. To avoid this problem, the upper part of the short plate 112 is extended outwards to form a square shape, increasing the stress structure at that position and reducing the deformation problem during subsequent use. Meanwhile, the connection between its three sets of structures gives it good support strength. Because of the multiple hollowed-out designs after connection, the required materials are also reduced, thus lowering the amount of materials needed for manufacturing.

[0018] For reference Figure 1-2 B-axis 12 is the central connecting end of the main body 1, which is used to maintain the central arc-shaped connection shape; it specifically includes a connecting rod 121, a reinforcing beam 122, a first herringbone beam 123 and a second herringbone beam 124. The two ends of the connecting rod 121 are connected to the A-axis 11 and the C-axis 13. The reinforcing beam 122 is set on the connecting rod 121. One end of the first herringbone beam 123 is connected to the A-axis 11, and the other end is connected to one end of the reinforcing beam 122. One end of the second herringbone beam 124 is connected to the C-axis 13, and the other end is connected to the surface of the reinforcing beam 122. The middle of the connection between the first herringbone beam 123 and the second herringbone beam 124 forms an installation groove 4. The connecting rod 121 is used to stabilize the overall arc-shaped structure, and the reinforcing beam 122 is set on it to strengthen it and effectively reduce the risk of breakage or deformation of the connecting rod 121. The first A-frame beam 123 and the second A-frame beam 124 further stabilize the arc-shaped arrangement of the connecting rod 121 and cooperate with the reinforcing beam 122 to improve the overall structural support strength and prevent deformation or breakage. At the same time, the connecting rod 121 forms a good connection between axis A 11 and axis C 13 through axis B 12. The first A-frame beam 123 and the second A-frame beam 124 are arranged opposite each other, and the mounting groove 4 formed between them can be used to lay wires and cables, facilitating circuit wiring. In addition, each of the two A-frame beams has a mounting position 5 at its opposite end, which can be used to install linear lights.

[0019] For reference Figure 1-2The bottom of the main body 1 is connected by a C-axis 13, which includes a vertical rod 131, a horizontal rod 132, and a connecting rod 133. One end of the horizontal rod 132 is perpendicularly connected to the surface of the vertical rod 131. One end of the connecting rod 133 is connected to the end of the horizontal rod 132 away from the vertical rod 131, and the other end is connected to one end of the connecting rod 121. This structure optimizes the bottom connection method through multi-rod linkage, which can not only effectively alleviate the connection stress caused by assembly errors, but also enhance the adaptability of the overall structure under movement or load changes, and further improve the stability and durability of the device.

[0020] Meanwhile, the two ends set between A-axis 11 and C-axis 13 can be adapted to connect with side panels 2 and top panels 3 of different thicknesses, thereby realizing the installation operation.

[0021] In this invention, the working steps of the device are as follows: During the installation of the RV body, the main body 1 is first positioned in the middle of the connection between the top panel 3 and the side panel 2, so that its arc-shaped structural outline fits tightly with the shape of the side panels; the connecting plate 111 of the A-axis 11 is adapted to the contact surface of the top panel 3. Through the combination of the connecting plate 111, the short plate 112 and the arc plate 113, the A-axis 11 is firmly attached to the surface of the top panel 3, while the direction of the arc plate 113 naturally transitions downward to the B-axis 12, ensuring a smooth transition of the connection structure between the top and the middle.

[0022] As the main structure extends downwards, the connecting rod 121, reinforcing beam 122, and the first and second chevron beams 123 and 124 included in the B-axis 12 work together to form a three-dimensional support frame. On the one hand, it maintains the arc-shaped stability of the overall structure, and on the other hand, it enhances the load-bearing capacity of the middle section through the reinforcing beam 122. The mounting groove 4 formed between the first and second chevron beams 123 and 124 can be used to lay cables in advance, which facilitates the reasonable layout of the internal circuit of the motorhome. At the same time, there are mounting positions 5 at the opposite ends of the chevron beams, which can realize the convenient integration of functional components such as linear lights, so that the structure can be both practical and aesthetically pleasing while having good support.

[0023] The far ends of C-axis 13 and B-axis 12 are connected to form the bottom connection structure of the main body 1. C-axis 13 consists of a vertical rod 131, a horizontal rod 132 and a connecting rod 133. The horizontal rod 132 is vertically connected to the surface of the vertical rod 131. One end of the connecting rod 133 is connected to the side of the horizontal rod 132 away from the vertical rod 131, and the other end is connected to the connecting rod 121 of B-axis. This bottom connection mechanism effectively absorbs deviation errors in the assembly process through the flexible cooperation of multiple rod linkages, ensuring that the side panel 2 can be stably connected with the bottom arc structure, improving structural adaptability and installation convenience.

[0024] The entire main body 1 forms a continuous arc-shaped frame connection from the top panel 3 to the side panel 2, which makes the two panels firmly connected; through multi-point force support, fatigue damage caused by local force concentration is avoided, and the stability, reliability and deformation resistance of the overall connection are improved.

[0025] The final assembled body connection structure not only has lightweight and high-strength structural performance, but also can be adapted to roof panels 3 and side panels 2 of different thicknesses to meet the needs of various vehicle models; at the same time, the reserved mounting slots 4 and mounting positions 5 in its structure facilitate the layout of electrical systems and lighting components, greatly improving the modular integration and craftsmanship of the motorhome body.

[0026] 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
