Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a pipe protection device for a vehicle that protects pipes installed under the floor of a vehicle body.

[Technical background of the invention and its problems] Along with wiring, various pipes for brakes, fuel, etc. are installed on the underside of the floor of the car body. FIG. 4 shows the conventional piping state, where 1 is the vehicle body, 2 is the front floor, and 3 is the rear floor. Regarding the fuel pipe 4, one end of the pipe 4 is connected to a fuel tank 5 provided on the rear side of the vehicle body 1, and the other end is connected to an engine 6 provided on the front side of the vehicle body 1. . The pipe 4 is installed along the lower surfaces of the front floor 2 and the rear floor 3, and the middle part of the pipe 4 is connected to the front floor 2 through a bracket 7.
and is fixed to the rear floor 3.

By the way, as shown in FIG. 5, the conventional bracket 7 is made by bending a plate-like body into a U-shape, and has flange portions 7a, 7a at both ends thereof. Then, attach both flange portions 7a, 7a to the front floor 2.
The pipe 4 is protected by spot welding to the lower surface of the bracket 7 and inserted into the hollow part of the bracket 7.

However, the conventional bracket 7 is simply a plate-shaped member bent into a U-shape as described above. Therefore, the front end 8 and the rear end 9 of the bracket 7 project at right angles to the lower surface of the front floor 2. Therefore, if the bracket 7 interferes with an obstacle 10 such as a stone on the road or the road surface while driving on a rough road, the bracket 7 may be damaged, and this damage may cause the pipe 4 to bend or break.

[Purpose of invention]

This idea was developed with attention to the above-mentioned circumstances, and its purpose is to prevent the bracket from being easily damaged even if the road surface or an obstacle on the road collides with the bracket that supports the pipe while the vehicle is running. The object of the present invention is to provide a vehicle pipe protection device that can protect pipes without doing anything.

[Summary of the idea]

In order to achieve the above object, this invention includes a front floor extending in the longitudinal direction of the vehicle body, a front end connected to the rear end of this front floor, and a rear end of the vehicle body extending from the connected end to the front floor extending in the longitudinal direction of the vehicle body. It consists of a rear floor having a flat part extending toward the front and a standing wall part extending upward from the rear end of the flat part, and pipes for brakes and fuel connected to the lower surface of this floor along the longitudinal direction of the vehicle body. A piping protection device for a vehicle that protects the middle part of piping, such as a pipe, with a bracket, and the bracket contacts the lower surface of the front floor in front of the connecting end, and contacts the flat surface of the rear floor behind the connecting end. The bracket extends in the longitudinal direction of the vehicle body so as to come into contact with the vertical wall part, and a bent part is formed at the rear end of the bracket and extends upward while being in contact with the vertical wall part, and is fixed to both the front floor and the rear floor. The front part has a downward slope towards the rear of the car body, and the rear part has a downward slope towards the front of the car body, creating the effect of a sliding surface against collisions with the road surface or obstacles. be.

[Example of idea]

An embodiment of this invention will be described below based on the drawings.

Figures 1 and 2 show a bracket 11 as a pipe protection device that is attached to the joint between the front floor 2 and rear floor 3, and is divided into two parts: a front bracket 12 and a rear bracket 13. . The front bracket 12 is formed into a substantially U-shape by drawing a metal plate, and its front end is closed by an inclined surface 14. Furthermore, a flange portion 15 is integrally provided on the upper edge of the front bracket 12. Further, the rear bracket 13 is similarly formed into a substantially U-shape by drawing a metal plate, and the whole is bent into an L-shape. Furthermore, a flange portion 16 is integrally formed at the opening edge of the rear bracket 13. The front end of the rear bracket 13 overlaps the rear end of the front bracket 12, and stepped portions 15a, 16a are formed in the flange portions 15, 16 located at the overlapping portion. Furthermore, the bent portion of the rear bracket 13 has an inclined surface 17.
This inclined surface 17 and the inclined surface 14 of the front bracket 12 are provided with insertion holes 19, 19 through which brake and fuel pipes 18, 18 are inserted.

Bracket 1 configured as described above
1 is fixed to the lower surface of the joint between the front floor 2 and the rear floor 3 by spot welding the flanges 15 and 16. Accordingly, the sloped surface 14 of the front bracket 12 slopes downwardly toward the rear of the vehicle, and the sloped surface 17 of the rear bracket 13 slopes downwardly toward the front of the vehicle. Therefore, even if an obstacle such as a road surface or a stone collides with the bracket 11 while driving, the inclined surface 14 of the front bracket 12 becomes a sliding surface when moving forward, and the inclined surface 17 of the rear bracket 13 becomes a slipping surface when moving backward, and the bracket 11 can be alleviated. Therefore, damage to the bracket 11 can be prevented and the pipe 1
Breakage of parts 9 and 19 can be prevented.

In addition, in the above embodiment, the bracket 1
1 is divided into two parts, a front bracket 12 and a rear bracket 13, but this invention is not limited to the above embodiment, and as shown in FIG. 3, it can be constructed integrally by drawing a metal plate. , a bracket 2 having a structure in which inclined surfaces 20 and 21 are formed at the front and rear parts.
Even if it is 2, the same effect is produced.

[Effect of idea]

As explained above, according to this invention, the middle part of the brake, fuel, etc. pipes connected to the lower surface of the floor of the vehicle body is fixed to the floor via the bracket, and the front part of the bracket is fixed to the floor through the bracket. A sloped surface is provided at the rear to provide a sliding surface effect against collisions with road surfaces and obstacles, which can reduce the impact applied to the bracket.
This has the effect of preventing damage and breakage of the bracket and pipe. Also,
The bracket extends in the longitudinal direction of the vehicle body so as to contact the lower surface of the front floor in front of the connecting end of the front floor and the rear floor, and to contact the flat surface of the rear floor behind the connecting end. Furthermore, a bent portion is formed at the rear end of the upper body that abuts the vertical wall portion and extends upward, and is fixed to both the front floor and the rear floor. Therefore, the length of the connecting portion with the floor can be substantially extended without increasing the length of the bracket in the front-rear direction. As a result, the bracket itself can be more securely fixed to the floor, and has sufficient strength even if an obstacle collides with the bracket from the front of the vehicle, especially if it is from the rear of the vehicle. The strength is sufficient as it has been Furthermore, the bracket is fixed so as to cover the connecting part between the front floor and the rear floor, increasing the rigidity of the connecting part and improving the rigidity of the entire vehicle body.
