[0026] The following describes the present invention based on embodiments. Those of ordinary skill in the art should understand that the attached drawings provided here are all for illustrative purposes and the drawings are not necessarily drawn to scale.

[0027] Unless the context clearly requires otherwise, the words such as "comprising", "including" and the like in the whole specification and claims should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, it is the meaning of "including but not limited to".

[0028] Note: The upper, lower, left, right and other orientations involved in the description process of this application are subject to the orientations shown in Figure 1 the figure.

[0029] This application provides a seat embedded structure, which includes an embedded installation part 1 and a connecting part 2, as shown in Figure 1 the figure. Among them, the embedded installation part 1 is fixedly arranged on the frame 3 through the connecting part 2. The embedded installation part 1 is used for fixedly connecting with a seat (not shown in the figure). The embedded installation part 1 plays a role in connecting the seat and the frame 3, and reliably installs the seat on the frame 3. Preferably, the embedded installation part 1 and the seat are fixedly connected together by welding or using fasteners such as screws and bolts to ensure the safety and reliability of the connection.

[0030] Further, the frame 3 includes a cross beam 31 extending along the width direction of the vehicle. The connecting part 2 is fixedly arranged at the end of the cross beam 31. There are multiple cross beams 31 arranged along the length direction of the vehicle. The cross beams 31 are parallel to each other and the distances between the cross beams 31 are equal. The multiple connecting parts 2 arranged at the ends of the cross beam 31 are fixedly arranged on the cross beam 31 by welding. The embedded installation part 1 is fixedly connected to two adjacent connecting parts 2 respectively to fix the embedded installation part 1 on the frame 3. The embedded installation part 1 extends along the length direction of the vehicle. Preferably, the frame 3 further includes multiple longitudinal beams 4 extending along the length direction of the vehicle. The multiple longitudinal beams 4 are arranged side by side along the width direction of the vehicle. The longitudinal beams 4 are parallel to each other and the distances between the longitudinal beams 4 are equal. The cross beam 31 and the longitudinal beam 4 are arranged perpendicular to each other to achieve the purpose of strengthening the structural strength of the frame. At the same time, a diagonal beam 5 can also be arranged along the connection line of the intersections of the cross beam 31 and the longitudinal beam 4 to further strengthen the structural strength of the frame 3. Preferably, the cross beam 31, the longitudinal beam 4 and the diagonal beam 5 of the frame 3 can be fixedly connected together by welding or fastener means, and a strengthening structure can also be arranged at their connection positions to further ensure the connection strength.

[0031] Further, as shown in Figure 3 , an installation protrusion 14 is provided on the embedded installation part 1. Preferably, the installation protrusion 14 is located at both ends of the embedded installation part 1 along the length direction. The width of the installation protrusion 14 is not greater than the dimension of the connecting part 2 along the width direction, so as to facilitate the fixed connection between the installation protrusion 14 and the side surface of the connecting part 2. Preferably, the installation protrusion 14 is a reinforcing rib plate protruding from the embedded installation part 1.

[0032] Further, as shown in Figure 2 , the connecting part has a chamber, and a connecting part reinforcing plate 21 is provided on the inner wall of the chamber. Preferably, the connecting part reinforcing plate 21 is provided on the inner top wall of the chamber. Of course, it can be understood that the connecting part reinforcing plate 21 can also be provided on any one or more other surfaces in the chamber to meet different design requirements.

[0033] In a specific embodiment, as shown in Figure 2 , the connecting part 2 is a wedge-shaped structure with a horizontal bottom surface. The bottom surface of the wedge-shaped structure is fixedly provided on the cross beam 31. The edge of the bottom surface of the wedge-shaped structure should be equal to or less than the edge of the cross beam 31, so as to provide better structural strength and not easily generate protruding sharp corners that may scratch people or objects. Preferably, the connection method between the bottom surface of the wedge-shaped structure and the cross beam 31 is preferably a welded connection. Preferably, the wedge angle of the wedge-shaped structure is 40° to 45°, so as to further improve the installation reliability.

[0034] Further, as shown in Figure 3 , the embedded installation part 1 includes a main body 11 extending along the length direction of the vehicle. Both ends of the main body 11 in the width direction are bent towards opposite directions to form a first bending part 12 and a second bending part 13. The installation protrusions 14 protrude from both side edges of the main body in the length direction.

[0035] Among them, the first bending part 12 is arranged close to the inner side of the vehicle, and the included angle between the first bending part 12 and the main body is 135° to 140°. The included angle between the second bending part 13 and the main body is 89° to 91°. The first bending part 12, the second bending part 13 and the main body 11 are smoothly transitioned to reduce the stress concentration problem at the connection position and further improve the overall strength of the embedded installation part 1.

[0036] Further, when the embedded installation part 1 is in the assembly position, the top surface of the main body 11 and the top surface of the wedge-shaped structure are located on the same inclined plane, so as to facilitate the installation of the seat and ensure the reliability and stability of the seat installation. The top surface of the first bending part 12 is a horizontal plane, and the second bending part 13 is bent downward in the vertical direction to facilitate the firm connection between the seat and the vehicle frame 3. Preferably, the connection between the embedded installation part 1 and the connecting part 2 is fixedly connected by welding.

[0037] In a preferred embodiment, the mounting protrusion 14 is a mounting rib plate protruding from the main body. On the bottom surface of the main body 11, there is a main body reinforcing rib plate 15. The main body reinforcing rib plate 15 can be arranged by successively welding a number of small reinforcing rib plates to the bottom surface of the main body 11. Of course, it can be understood that a relatively large reinforcing plate formed integrally or a large reinforcing rib plate formed by welding a number of relatively small reinforcing rib plates can also be selected and arranged on the bottom surface of the main body 11 to meet different structural strength requirements.

[0038] During the vehicle manufacturing process, the seat is installed on the vehicle frame 3 through the above-mentioned seat pre-embedded structure. The main body 11 of the seat and the pre-embedded installation part 1 are preferably fixedly connected by welding or fasteners. By setting the pre-embedded installation part, the welding area and the contact area can be increased, thereby improving the connection strength and better dispersing the acting force to the vehicle frame 3.

[0039] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0040] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
