[0019] The preferred embodiments of the utility model are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.
[0020] Referring to Figure 1 , Figure 2 and Figure 3 , the utility model discloses a ceiling decorative plate and D column cooperation structure, including ceiling decorative plate 1 and vehicle D column 2, one side of the outer lateral wall of ceiling decorative plate 1 and vehicle D column 2 is provided with reinforcing rib 4, the design of reinforcing rib 4 not only enhances the load-carrying capacity of structure, also helps to reduce the deformation and noise generated due to vibration and impact;
[0021] One end of ceiling decorative plate 1 is provided with connecting assembly 3, connecting assembly 3 is used to make ceiling decorative plate 1 and vehicle D column 2 connect each other, and through adjusting the angle of the cooperation surface between ceiling decorative plate 1 and vehicle D column 2, the cooperation gap between ceiling decorative plate 1 and the flange cooperation plate 31 and vehicle D column 2 is weakened, and the cooperation surface difference between ceiling decorative plate 1 and vehicle D column 2 is eliminated simultaneously.
[0022] Referring to Figure 1 , Figure 2 and Figure 3 , connecting assembly 3 includes flange cooperation plate 31, flange cooperation plate 31 extends from one end of ceiling decorative plate 1, flange cooperation plate 31 is overlapped on vehicle D column 2, and the cooperation surface of flange cooperation plate 31 and vehicle D column 2 forms a predetermined angle, to further weaken the cooperation gap, connecting assembly 3 also includes connecting piece 32 arranged on the side of flange cooperation plate 31 away from vehicle D column 2, ceiling decorative plate 1, flange cooperation plate 31 and connecting piece 32 are integrally injection molded;
[0023] Ceiling decorative plate 1, flange cooperation plate 31 and connecting piece 32 adopt integrally injection molding, which not only can reduce assembly process, but also can ensure the close connection and overall stability between each component as much as possible, one side in connecting piece 32 is provided with buckle groove 33, and the side of connecting piece 32 close to buckle groove 33 is provided with positioning groove 34;
[0024] The outer lateral wall of vehicle D column 2 close to buckle groove 33 is fixedly connected with L-shaped buckle plate 35 matched with buckle groove 33, by buckling L-shaped buckle plate 35 in buckle groove 33, the stable connection between vehicle D column 2 and ceiling decorative plate 1 can be realized, and the outer lateral wall of vehicle D column close to positioning groove 34 is fixedly connected with positioning pin 36 matched with positioning groove 34;
[0025] In the assembly process, the positioning pin 36 is inserted into the positioning groove 34, the vehicle D column 2, the L-shaped buckle plate 35 and the positioning pin 36 are integrally injection molded, and the vehicle D column 2, the L-shaped buckle plate 35 and the positioning pin 36 also adopt integrally injection molding. The same can reduce the assembly process while trying to ensure the firm connection between the L-shaped buckle plate 35 and the positioning pin 36 and the vehicle D column 2, thereby improving the reliability and stability of the assembly.
[0026] The working principle of the utility model is:
[0027] In the process of assembling the ceiling decoration plate 1 and the vehicle D column, the manufactured ceiling decoration plate 1 is first transported to the assembly station, and the flange fitting plate 31 is slowly overlapped on the vehicle D column 2. During the overlapping process, the flange fitting plate 31 is placed according to the predetermined angle of the fitting surface of the flange fitting plate 31 and the vehicle D column 2, and the operator can use a simple positioning tool or refer to the mark line on the vehicle skeleton to ensure the approximate position of the flange fitting plate 31 on the vehicle D column 2 is accurate.
[0028] Then, the L-shaped buckle plate 35 on the outer side wall of the vehicle D column 2 is aligned with the buckle groove 33 in the connecting piece 32, and a slight pressure is applied, so that the L-shaped buckle plate 35 gradually slides into the buckle groove 33. Due to the shape adaptability of the L-shaped buckle plate 35 and the buckle groove 33 and the elastic properties of the L-shaped buckle plate 35, the L-shaped buckle plate 35 will produce a certain elastic deformation during the buckling process to adapt to the possible small tolerance. When buckling is completed, stable transverse connecting force can be provided to prevent displacement of the ceiling decoration plate 1 in the horizontal direction.
[0029] During this process, the angle of the fitting surface of the flange fitting plate 31 in the connecting assembly 3 and the vehicle D column 2 remains stable, and the relative position of the two is further constrained through the buckling of the L-shaped buckle plate 35 and the buckle groove 33, so that the effect of the fitting surface angle can be continuously exerted, thereby weakening the fitting gap between the ceiling decoration plate 1, the flange fitting plate 31 and the vehicle D column 2.
[0030] At the same time, the positioning pin 36 on the outer side wall of the vehicle D column 2 will also be aligned with the positioning groove 34 on the connecting piece 32. The cooperation between the positioning pin 36 and the positioning groove 34 has a precise guiding function, which can guide the accurate butt joint of the ceiling decoration plate 1 and the vehicle D column 2 during the assembly process. When the positioning pin 36 is inserted into the positioning groove 34, the freedom of the ceiling decoration plate 1 in multiple directions is further limited, ensuring the accuracy and stability of the connection.
[0031] In addition, the cooperation between the positioning pin 36 and the positioning groove 34 also helps to maintain the fitting surface angle between the flange fitting plate 31 and the vehicle D column 2, preventing the angle from changing due to other external factors during the assembly process, thereby ensuring the effect of eliminating the fitting surface difference between the ceiling decoration plate 1 and the vehicle D column 2.
[0032] It should be pointed out finally that the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
