Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive rear floor assemblies, and in particular to an automotive rear floor assembly. Background Technology
[0002] Automotive floors are generally divided into front floor assembly, middle floor assembly, and rear floor assembly. Some may also group the middle floor assembly and rear floor assembly together as the rear floor assembly. The rear floor is usually a single piece welded to the frame and side panels, etc. The rear floor assembly is part of the vehicle frame and has a load-bearing function.
[0003] In existing automotive rear floor assemblies, a plate-like structure is used during operation. If the plate is too thick, it will increase the overall weight of the vehicle, while if the plate is too thin, it will affect the vehicle's safety. Therefore, the traditional approach is to increase the thickness of the anti-collision beam. However, if the anti-collision beam shifts, it will directly affect the automotive floor assembly, failing to achieve effective safety protection and causing inconvenience in use. Utility Model Content
[0004] The purpose of this utility model is to provide a rear floor assembly for automobiles that solves the problem that the traditional method simply increases the thickness of the anti-collision beam, but when the anti-collision beam shifts, it will directly affect the automobile floor assembly and fail to achieve effective safety protection.
[0005] To achieve the above objectives, a rear floor assembly for automobiles is provided, comprising: a floor assembly, characterized in that a plurality of first convex plates and second convex plates are attached to the upper and lower surfaces of the floor assembly, an H-shaped plate is fixedly connected to the inner side of the first convex plates and the second convex plates, and a spare tire recess groove is provided on the rear side of the upper surface of the floor assembly, and a rubber ring is fixedly connected to the inner wall of the spare tire recess groove.
[0006] According to the aforementioned automobile rear floor assembly, a plurality of weld joints are welded between the rubber ring and the floor assembly.
[0007] According to the aforementioned automobile rear floor assembly, both sides of the first convex plate and the second convex plate are provided with second through holes.
[0008] According to the aforementioned automobile rear floor assembly, the first convex plate, the second convex plate, and the H-shaped plate all have first through holes at both ends, and fastening bolts pass through the first through holes and the second through holes.
[0009] According to the aforementioned automotive rear floor assembly, mounting bolts penetrate each of the four corners of the floor assembly.
[0010] According to the aforementioned automotive rear floor assembly, the first convex plate and the second convex plate are distributed in a U-shape on their upper and lower sides.
[0011] The above-mentioned solution has the following beneficial effects:
[0012] 1. This utility model comprises a first convex plate, a second convex plate, and an H-shaped plate. The first and second convex plates are U-shaped and evenly distributed on the upper and lower surfaces of the floor assembly. Through bolts passing through the second through hole, through-installation and fixation can be achieved. After fixation, the inner sides of the first and second convex plates are supported laterally and longitudinally by the H-shaped plate. When the floor assembly is subjected to lateral or longitudinal impact force, the convex structure can provide reinforced support. This structure can achieve reinforced support for the floor assembly and has a better compressive resistance than traditional plate structures.
[0013] 2. This utility model uses a rubber ring and a spare tire recess to install the spare tire. The rubber ring increases rubber support to prevent abnormal noise caused by collisions, and the rubber ring facilitates subsequent replacement.
[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 1-4 This utility model discloses a rear floor assembly for automobiles, comprising: a floor assembly 1, wherein a plurality of first convex plates 6 and second convex plates 10 are attached to the upper and lower surfaces of the floor assembly 1, and H-shaped plates 11 are fixedly connected to the inner sides of the first convex plates 6 and second convex plates 10. Since the inner sides of the first convex plates 6 and second convex plates 10 are supported laterally and longitudinally by the H-shaped plates 11, the convex structure can provide reinforcement support when the floor assembly 1 is subjected to lateral or longitudinal impact force. A spare tire recess 3 is provided on the rear side of the upper surface of the floor assembly 1, and a rubber ring 5 is fixedly connected to the inner wall of the spare tire recess 3. The spare tire is installed in the spare tire recess 3, and the rubber ring 5 provides rubber support to prevent abnormal noise caused by collision.
[0024] Several welding heads 4 are welded between the rubber ring 5 and the floor assembly 1. The welding heads 4 facilitate the destruction of the welding heads 4 when the rubber ring 5 is damaged, and then a new rubber ring 5 is replaced. The welding heads 4 are then welded to the outer arc-shaped plate of the rubber ring 5 using welding equipment to achieve a fixing effect. The first convex plate 6 and the second convex plate 10 are provided with second through holes 9 on both sides. The first convex plate 6, the second convex plate 10 and the H-shaped plate 11 are provided with first through holes 8 at both ends. Fastening bolts 7 pass through the first through holes 8 and the second through holes 9. The first convex plate 6 and the second convex plate 10 are distributed in a U-shape on the upper and lower surfaces of the floor assembly 1. The fastening bolts 7 pass through the second through holes 9 to achieve through-installation and fixing. The four corners of the floor assembly 1 are provided with mounting bolts 2. After the floor assembly 1 is connected to the frame, the mounting bolts 2 can increase the firmness of the connection with the frame. The first convex plate 6 and the second convex plate 10 are distributed in a U-shape on the upper and lower sides.
[0025] Working principle: In use, the floor assembly 1 is first connected to the frame. After connection, the mounting bolts 2 can increase the firmness of the connection with the frame. Then, the first convex plate 6 and the second convex plate 10 are evenly distributed in a U-shape on the upper and lower surfaces of the floor assembly 1. The fastening bolts 7 pass through the second through hole 9 to achieve through-installation and fixation. After fixation, the inner sides of the first convex plate 6 and the second convex plate 10 are supported laterally and longitudinally by the H-shaped plate 11. After support, when the floor assembly 1 is subjected to lateral or longitudinal impact force, it can play a role in strengthening the support of the convex structure. Then, the spare tire recess 3 is used to install the spare tire, and the rubber ring 5 adds rubber support to prevent abnormal noise caused by collision.
