AI Technical Summary
The existing non-load-bearing vehicle rear floor suspension installation structure lacks a connection structure, which leads to obstacles in transmission, and the structural strength is weak, making it difficult to operate stably under extreme road conditions.
A suspension installation structure including a vehicle body beam is designed. The vehicle body beam is a U-shaped structure with an opening upward opening. A beam reinforcement plate and a suspension mounting bracket are welded on the bottom plate. The suspension body is screwed to the suspension nut box through the suspension installation reinforcement plate, realizing direct contact and force transmission between the suspension body and the vehicle body beam.
The cross beam of the vehicle body can achieve force transmission through avoiding stress concentration, improving the overall structural strength, optimizing the space layout, saving installation space, and helping to achieve the vehicle's lightweight goal.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile assembly, in particular to a suspension installation structure at the rear floor of a non-load-bearing vehicle. Background Art
[0002] For non-load-bearing vehicles such as off-road SUVs and engineering vehicles, they not only emphasize comfort, but also require higher safety and reliability. Therefore, as a suspension body connecting the body and the frame, it must be reliably installed between the body and the frame to ensure that the vehicle can run stably under various extreme road conditions. The suspension body must not be loose, vibrate or make abnormal noises, and must not interfere with or collide with other parts. The suspension body located at the rear floor of the vehicle is generally installed in a "threshold support box fixing" manner, that is, first install support boxes at the thresholds on the outside of the frame longitudinal beam, and then install the suspension body through the support boxes. It is low-cost and easy to install, but since there is no connection structure between the left and right thresholds, the force transmission is blocked and the structural strength is weak. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a suspension installation structure at the rear floor of a non-load-bearing vehicle, which can specifically adopt the following technical solutions:
[0004] The suspension mounting structure at the rear floor of a non-load-bearing vehicle described in the utility model includes a body crossbeam arranged between the door sills on both sides, the body crossbeam is a U-shaped structure with an opening upward, a crossbeam reinforcement plate located in the middle and suspension mounting brackets located on both sides are welded to the bottom plate of the body crossbeam, and the two side vertical plates of the body crossbeam are welded to the rear floor to form a crossbeam mounting cavity, the crossbeam reinforcement plate and the suspension mounting bracket are located in the crossbeam mounting cavity, and the suspension body connected to the suspension mounting bracket is located outside the crossbeam mounting cavity.
[0005] The bottom plate and the vertical plates on both sides of the vehicle body cross beam are an integrally formed structure.
[0006] The top of the vertical plate of the vehicle body cross beam is provided with an outer flange structure which is welded and connected with the rear floor.
[0007] The suspension mounting brackets are symmetrically arranged at both ends of the vehicle body cross beam, and each suspension mounting bracket comprises a suspension mounting reinforcement plate welded to the bottom plate of the vehicle body cross beam, and a suspension nut box is welded on the suspension mounting reinforcement plate.
[0008] The suspension body is arranged at the bottom of the vehicle body cross beam, passes through the vehicle body cross beam bottom plate, the suspension installation reinforcement plate and is screwed to the suspension nut box.
[0009] A seat bracket and a jack bracket are arranged in the crossbeam installation cavity.
[0010] The suspension mounting structure at the rear floor of a non-load-bearing vehicle provided by the utility model has a simple structure and is easy to install. A suspension mounting reinforcement plate is integrated in the cavity of the vehicle body cross beam, and the suspension body is installed at the bottom of the cross beam, so that the vehicle suspension body is in direct contact with the vehicle body cross beam, and force transmission is achieved through the vehicle body cross beam, thus avoiding stress concentration and improving the overall structural strength. The above-mentioned method of arranging the suspension mounting reinforcement plate in the cavity of the vehicle body cross beam can reduce the impact on surrounding mechanisms, is conducive to saving installation space, and helps to achieve the goal of lightweighting the vehicle.

[0015] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific installation process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0016] like Figure 1-4As shown, the suspension installation structure at the rear floor of the non-load-bearing vehicle described in the utility model includes a body crossbeam 2 arranged between the door sills 1 on both sides. The body crossbeam 2 is a U-shaped structure with an opening facing upward, and its bottom plate 21 and the vertical plates 22 on both sides are an integrally formed structure. Among them, a crossbeam reinforcement plate 3 located in the middle and a suspension installation bracket 4 located on both sides are welded to the bottom plate 21 of the body crossbeam 2, and the vertical plates 22 on both sides of the body crossbeam 2 are welded and connected to the rear floor 5 to form a crossbeam installation cavity. The above-mentioned crossbeam reinforcement plate 3 and the suspension installation bracket 4 are located in the crossbeam installation cavity, and the suspension body 6 connected to the suspension installation bracket 4 is located outside the crossbeam installation cavity. In order to facilitate welding and to improve the stability of the overall structure, the top surface of the vertical plates 22 on both sides of the body crossbeam 2 is a straight structure, and both are provided with an outer flange 23 structure welded and connected to the rear floor 5. There are two suspension mounting brackets 4, which are symmetrically mounted at both ends of the vehicle body cross beam 2; each suspension mounting bracket 4 includes a suspension mounting reinforcement plate 41 welded to the bottom plate 21 of the vehicle body cross beam 2, and a suspension nut box 42 is welded on each suspension mounting reinforcement plate 41. The suspension body 6 is located at the bottom of the vehicle body cross beam 2, and passes through the bottom plate 21 of the vehicle body cross beam 2, and the suspension mounting reinforcement plate 41 is screwed to the suspension nut box 42. The above installation method realizes direct contact between the suspension body 6 and the vehicle body cross beam 2, which can conduct force through the vehicle body cross beam 2, fully avoid stress concentration, and improve the strength of the overall structure. At the same time, the vehicle body cross beam 2 and the rear floor 5 form a cross beam installation cavity, which effectively reduces the space under the floor. Further, the suspension mounting bracket 4, the seat mounting bracket, the jack bracket and other components can be installed in the above beam installation cavity to provide installation support for the suspension body 6, the seat, the jack and other components, which is not only conducive to optimizing the space layout and saving costs, but also conducive to improving the overall structural strength.
[0017] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
