Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the temporary pipe fixing structure of the present invention will be described with a fuel pipe as a pipe that can be bent and deformed.
< embodiment 1 >
Fig. 1 is a perspective view showing a vehicle body rear floor to which a pipe temporary fixing structure of the present invention is applied. In fig. 1, an arrow FR shows the front of the vehicle body; the arrow LH shows the left of the vehicle body; arrow RH shows the right of the body; arrow UP shows UP.
As shown in fig. 1, the rear floor 1 is a panel (vehicle body panel) constituting a rear portion of an underbody and a trunk floor. A plurality of (two in the present embodiment) cross members 11, 12 extending in the vehicle width direction are joined to the top surface of the rear floor 1. Two rear side members 13, 14 (see fig. 5) extending in the vehicle body longitudinal direction are joined to the bottom surface of the rear floor 1.
In addition, two access ports 15 are provided in the rear floor 1. The access opening 15 is provided to ensure an operation space for a maintenance worker to perform a vehicle maintenance operation. The access opening 15 is a circular opening in plan view. A cylindrical vertical wall 16 extending upward and an annular flange 17 bent inward from the upper end edge of the vertical wall 16 are formed at the opening edge of the access opening 15 (see fig. 3 showing the access opening 15 and its periphery in an enlarged manner).
An engine, not shown, is mounted on the front portion of the vehicle body. Specifically, an engine (in-vehicle equipment) is mounted in an engine compartment at the front of the automobile.
Further, a fuel tank 2 (see fig. 5) is disposed below the rear floor 1. The oil tank 2 is disposed between the rear side members 13 and 14, as shown in fig. 5 described later. The fuel tank 2 is connected to the engine through a fuel pipe 3 made of rubber and capable of bending and deforming. That is, the fuel in the fuel tank 2 is delivered to the fuel supply apparatus of the engine through the fuel pipe 3.
In the production of automobiles, it is sometimes necessary to connect one end of the fuel pipe 3 to the fuel supply apparatus of the engine before loading the fuel tank 2 after the engine is mounted on the automobile body. Conventionally, in this case, the other end of the fuel pipe (the end not connected to the fuel tank) sags. In this case, the fuel pipe may hinder the assembly work of assembling other parts on the vehicle body thereafter.
The present embodiment is characterized in that a temporary fixing member 4 for temporarily fixing the fuel pipe 3 to the vehicle body is provided. Fig. 2 is a perspective view showing the temporary fixing member 4. Fig. 3 is a perspective view showing an operation of temporarily fixing the fuel pipe 3 to the rear floor 1 by the temporary fixing member 4. Fig. 4 is a sectional view taken along line IV-IV in fig. 3.
As shown in fig. 2 to 4, the temporary fixing member 4 is integrally formed by the pipe holding portion 5, the hook portion 6, and the lock portion 7. In addition, the temporary fixing member 4 is made of a resin material.
The pipe holding portion 5 is a portion for holding a predetermined portion of the fuel pipe 3. Here, the predetermined portion is a portion near an end of the other end of the fuel pipe 3 that is not connected to the fuel tank 2, and is hereinafter referred to as a free end predetermined portion 31. The free end predetermined portion 31 of the fuel pipe 3 is spaced from a portion connected to the fuel tank 2 by a predetermined distance.
The pipe holding portion 5 includes a circular arc portion 51 having an inner surface corresponding to the shape of the outer peripheral surface of the fuel pipe 3, and an opening 53 that opens a space 52 inside the circular arc portion 51 in a certain direction (left side in fig. 2). The opening width dimension (dimension t in fig. 4) of the opening 53 is configured to be slightly smaller than the outer diameter dimension of the fuel pipe 3.
The hook portion 6 is formed in a shape that opens downward. Specifically, the hook portion 6 includes a 1 st vertical portion 61, a horizontal portion 62, and a 2 nd vertical portion 63. The 1 st vertical portion 61 extends upward from the top surface of the arc portion 51 of the pipe holding portion 5. The horizontal portion 62 extends horizontally (leftward in fig. 2) from the upper end of the 1 st vertical portion 61. The 2 nd vertical portion 63 extends downward from the front end of the horizontal portion 62.
The locking portion 7 is connected to the pipe holding portion 5. The lock portion 7 can be inserted into a lock opening 21 (see fig. 5) formed in the fuel tank 2 described later and locked.
The lock portion 7 includes a umbrella portion 71, a plug 72, and two lock pieces 73. The pipe holding portion pin 72 is a cylindrical member extending downward from the lower portion of the pipe holding portion 5. The outer diameter of the plug pin 72 substantially corresponds to the inner diameter of the lock opening 21 described later. The umbrella-shaped portion 71 is configured to extend like an umbrella from the upper end of the plug 72 toward the outside with the plug 72 as the center axis and to be inclined downward. Two locking pieces 73 are formed on the outer peripheral surface of the lower end portion of the plug 72. The two locking pieces 73 are formed in a curved shape that curves in directions away from each other while extending upward.
Next, an operation of temporarily fixing the fuel pipe 3 to the rear floor 1 will be described.
As shown in fig. 3, a free end predetermined portion 31 of the fuel pipe 3, one end of which is connected to the engine, is fitted into the pipe holding portion 5 of the temporary fixing member 4. Specifically, the free end predetermined portion 31 of the fuel pipe 3 is fitted into the circular arc portion 51 from the opening portion 53 of the pipe holding portion 5.
In this state, as shown in fig. 3 and 4, the hook portion 6 of the temporary fixing member 4 is hung on the upper end of the vertical wall 16 which is the opening edge portion of the access opening 15. Then, as shown in fig. 4, the flange portion 17 of the access opening 15 is brought into contact with the lower surface of the horizontal portion 62 of the hook portion 6, so that the free end predetermined portion 31 of the fuel pipe 3 can be temporarily fixed to the rear floor 1 by the temporary fixing member 4.
By temporarily fixing the predetermined free end portion 31 of the fuel pipe 3 to the rear floor 1, the other end of the fuel pipe 3, which is not connected to the fuel tank 2, can be prevented from sagging. Therefore, it is possible to avoid the fuel pipe 3 from interfering with the subsequent assembly work for assembling other components on the vehicle body.
After the fuel tank 2 is mounted on the vehicle body, the temporary fixing member 4 holding the fuel pipe 3 is removed from the access opening 15 to release its temporary fixing state, then the other end of the fuel pipe 3 is connected to the fuel tank 2, and the fuel pipe 3 is fixed to the top surface of the fuel tank 2 by the temporary fixing member 4.
Fig. 5 is a perspective view showing that the fuel pipe 3 is fixed to the top surface of the fuel tank 2 by the temporary fixing member 4. As shown in fig. 5, the upper plate of the fuel tank 2 has a two-layer structure, but only the upper plate of the upper layer is formed with the lock opening 21. That is, the lock opening 21 does not communicate with the inside of the fuel tank 2 (the space in which fuel is stored). Specifically, as shown in fig. 5, the locking portion 7 of the provisional fastening member 4 is inserted into the lock opening 21 of the fuel tank 2, and the provisional fastening member 4 is locked on the ceiling surface of the fuel tank 2. That is, when the lock portion 7 is inserted into the lock opening 21, the lock piece 73 comes into contact with the opening edge of the lock opening 21 and then elastically deforms inward, and when the lock piece 73 passes through the opening edge of the lock opening 21, the lock piece 73 returns to its original shape and is locked by the opening edge of the lock opening 21, and the fuel pipe 3 is fixed to the ceiling surface of the fuel tank 2.
In this way, by fixing the fuel pipe 3 to the top surface of the fuel tank 2, the fuel pipe 3 can be prevented from moving on the top surface of the fuel tank 2, so that the stability of the connection between the fuel pipe 3 and the fuel tank 2 can be enhanced. Therefore, the temporary fixing member 4 has a function of temporarily fixing the free end predetermined portion 31 of the fuel pipe 3 to the rear floor 1, and a function of fixing the free end predetermined portion 31 of the fuel pipe 3 to the top surface of the fuel tank 2 after the temporary fixing state is released. That is, the temporary fixing member 4 can be effectively used as a member for temporarily fixing the free end predetermined portion 31 of the fuel pipe 3, and as an auxiliary fixing member for fixing the fuel pipe 3 to the ceiling surface of the fuel tank 2.
< embodiment 2 >
Next, embodiment 2 of the present invention will be explained. In the present embodiment, the structure of the temporary fixing member is different from that in embodiment 1 described above. Therefore, the structure of the temporary fixing member will be mainly described.
Fig. 6 is a perspective view showing the temporary fixing member 8. Fig. 7 is a perspective view showing an operation of temporarily fixing the fuel pipe 3 to the rear floor 1 by the temporary fixing member 8. Fig. 8 is a sectional view taken along line VIII-VIII in fig. 7.
As shown in fig. 6 to 8, the temporary fixing member 8 is integrally formed by the pipe holding portion 9 and the hook portion 6.
Specifically, the pipe holding portion 9 in the present embodiment includes a main body portion 91, a 1 st arc portion 92, and a 2 nd arc portion 93. The main body 91 is formed as a notched annular cylinder having a predetermined width dimension (dimension t1 in fig. 6) in the axial direction (the direction of the central axis O).
The 1 st arc portion 92 is configured to extend from one end of the notch of the main body portion 91 by a predetermined length in the circumferential direction of the main body portion 91, and has an axial (center axis O direction) width dimension that is approximately half the width dimension of the main body portion 91 (dimension t2 in fig. 6).
The 2 nd arc portion 93 is formed to extend from the other end of the notch of the main body portion 91 by a predetermined length in the circumferential direction of the main body portion 91, and has an axial (center axis O direction) width dimension that is approximately half the width dimension of the main body portion 91 (dimension t3 in fig. 6).
The 1 st arc portion 92 and the 2 nd arc portion 93 are configured to be relatively movable (elastically deformable) in the circumferential direction, and to overlap each other in the axial direction (the center axis O direction) of the pipe holding portion 9.
The two hook portions 6 are provided at the end of the 1 st arc portion 92 and the end of the 2 nd arc portion 93, respectively. The shape of the hook portion 6 is the same as that of the hook portion 6 in embodiment 1.
The pipe holding portion 9 has an inner diameter equal to or smaller than an outer diameter of the fuel pipe 3 in a state where no external force acts on the 1 st arc portion 92 and the 2 nd arc portion 93. When an external force in the counterclockwise direction in fig. 6 is applied to the 1 st arc portion 92 and an external force in the clockwise direction in fig. 6 is applied to the 2 nd arc portion 93, the inner diameter of the pipe holding portion 9 is enlarged.
Next, the operation of temporarily fixing the fuel pipe 3 to the rear floor 1 in the present embodiment will be described.
First, the free end predetermined portion 31 of the fuel pipe 3, one end of which is connected to the engine, is fitted into the pipe holding portion 9 of the temporary fixing member 8. Specifically, the two hook portions 6 are pinched to apply an external force F1 in the counterclockwise direction in fig. 6 to the 1 st arc portion 92 and an external force F2 in the clockwise direction in fig. 6 to the 2 nd arc portion 93, thereby expanding the inner diameter of the pipe holding portion 9. When the inner diameter of the pipe holding portion 9 is larger than the outer diameter of the fuel pipe 3, the fuel pipe 3 is inserted into the pipe holding portion 9 and the external forces F1 and F2 are released, so that the free end predetermined portion 31 of the fuel pipe 3 can be clamped and held by the pipe holding portion 9.
In this state, as shown in fig. 7, one hook portion 6 of the temporary fixing member 8 is hooked on the upper end of the vertical wall 16 at the opening edge portion of the access opening 15. As shown in fig. 8, the flange portion 17 of the access opening 15 is brought into contact with the lower surface of the horizontal portion 62 of the hook portion 6, whereby the free end predetermined portion 31 of the fuel pipe 3 can be fixed to the rear floor 1.
In the present embodiment, since the fuel pipe 3 is temporarily fixed to the rear floor 1, the other end of the fuel pipe 3, which is not connected to the fuel tank 2, can be prevented from sagging, and the fuel pipe 3 can be prevented from interfering with the subsequent assembly work of assembling other components on the vehicle body.
The present invention is not limited to the description of the above embodiments, and can be modified as appropriate. For example, in the above embodiments, the fuel pipe 3 is described as an example of a pipe that can be bent and deformed, but the pipe temporary fixing structure of the present invention is also applicable to other types of bendable pipes.
