[0008] Embodiments of the present invention will be described below with reference to the drawings. Note that the drawings are schematic and may differ from actual examples. Furthermore, the following embodiments are illustrative examples of devices and methods for realizing the technical concept of the present invention, and do not limit the configuration to those described below. In other words, the technical concept of the present invention can be modified in various ways within the technical scope described in the claims.

[0009] 《Embodiment》 "composition" Figure 1 shows vehicle 11. Vehicle 11 is equipped with side sills 12 and piping 13 (through members). The side sills 12 are provided on both the left and right sides of the vehicle body and form closed cross-sectional sections that extend in the longitudinal direction of the vehicle body. The side sills 12 are joined to the vehicle body frame, such as side members and cross members (not shown). The piping 13 extends in the longitudinal direction of the vehicle body and is inserted into the section of the side sills 12. The piping 13 serves as a passage for, for example, a heat transfer medium for the air conditioning system, cooling water for the engine or motor, or compressed air for the air suspension.

[0010] Figure 2 shows the side sill internal fixing structure 14. The side sill internal fixing structure 14 is a structure for fixing pipes 13 inserted through the side sill 12, and comprises the side sill 12, pipes 13 (insertion members), a guide member 15, and a clip member 16. The side sill 12 has a closed section 21 extending in the longitudinal direction of the vehicle body formed by extrusion molding of a metal such as aluminum. The section 21 is a rectangle or the like that is long in the width direction when viewed from the longitudinal direction of the vehicle body, and a pair of projections 22 and 23 are formed on its inner circumferential surface. There is one projection 22 and one projection 23 on each side in the width direction when viewed from the longitudinal direction of the vehicle body. Multiple pipes 13 are inserted through the section 21 in a line in the vehicle width direction. The guide member 15 is fixed to the section 21 by fitting into the pair of projections 22 and 23. The clip member 16 fits into the guide member 15 and holds the pipes 13. Here, as an example, four pipes 13 are held.

[0011] Figure 3 shows projections 22 and 23. Figure (a) shows a pair of projections 22 and 23. When viewed from the front-rear direction of the vehicle body, projection 22 rises from the floor surface 24 of compartment 21, with its tip protruding inward in the width direction. The tip of projection 22 faces the floor surface 24 of compartment 21. When viewed from the front-rear direction of the vehicle body, projection 23 protrudes inward in the width direction from the side surface 25 of compartment 21. The entire projection 23 faces the floor surface 24 of compartment 21. Here, projections 22 and 23 are formed with different shapes, but this is not limited to this. That is, as shown in Figure (b), a pair of projections 22 of the same shape may be formed, or as shown in Figure (c), a pair of projections 23 of the same shape may be formed.

[0012] Figure 4 shows the guide member 15. Figure (a) shows the guide member 15 as viewed from one side in the front-rear direction of the vehicle body. The guide member 15 is made of resin, for example, and comprises a plate portion 31 and a flange portion 32, and is formed in a hat shape when viewed from the front-rear direction of the vehicle body. The plate portion 31 is formed in a plate shape along the floor surface 24 of the compartment 21, that is, along the front-rear direction and the width direction of the vehicle body. The flange portions 32 are formed at both ends in the width direction of the guide member 15, are parallel to the plate portion 31, and are positioned below the plate portion 31. When the guide member 15 is inserted into the compartment 21, the center in the width direction is separated from the floor surface 24 of the compartment 21, and only the ends in the width direction are in contact with the floor surface 24 of the compartment 21.

[0013] Figure (b) shows the guide member 15 as viewed from below. The guide member 15 has dimensions of approximately 50 to 80 cm in the longitudinal direction of the vehicle body. On both sides of the plate portion 31 in the longitudinal direction of the vehicle body, there is one fastening hole 33 formed, which penetrates in the thickness direction and into which the clip member 16 fits. The fastening hole 33 is approximately rectangular when viewed from above or below. A nut 34 is fixed to the downward-facing surface of the central plate portion 31 in the longitudinal direction of the vehicle body. The nut 34 is an insert nut embedded in the boss, and is embedded during or after the molding of the guide member 15. The guide member 15 is fastened to the side sill 12 by fitting a bolt onto the nut 34 (see Figure 7).

[0014] Multiple openings 35 are formed in the plate portion 31, penetrating in the thickness direction and aligned along the longitudinal direction of the vehicle body. The openings 35 are approximately rectangular when viewed from above and below, and there are four of them aligned along the longitudinal direction of the vehicle body. Specifically, the openings 35 are located on both sides of the nut 34 and on the outer side in the longitudinal direction of the vehicle body at each fastening hole 33. Since the openings 35 become weight-reducing gaps for the guide member 15, the remaining plate portion 31 is reinforced with ribs along the width direction and the vertical direction. The guide member 15 has a connecting convex portion 36 formed at one end in the vehicle body longitudinal direction and a connecting concave portion 37 formed at the other end in the vehicle body longitudinal direction. The connecting convex portion 36 protrudes in one direction in the vehicle body longitudinal direction and is cylindrical extending in the vertical direction, and is formed at two locations along the width direction. The connecting concave portion 37 extends in the vertical direction and is cylindrical to fit outside the connecting convex portion 36, and is formed at two locations along the width direction. By fitting the connecting convex portion 36 and the connecting concave portion 37 together in the vertical direction, a plurality of guide members 15 can be connected in the vehicle body longitudinal direction.

[0015] FIG. 5 is a view showing the clip member 16. The clip member 16 is made of, for example, resin, and the dimension in the vehicle body longitudinal direction is about 1 to 2 cm, for example. On the lower surface of the clip member 16, an insertion portion 41 that protrudes downward and fits into the fastening hole 33 is formed. The insertion portion 41 fits into the fastening hole 33 by snap fit, and the head passing through the fastening hole 33 is hooked on the edge of the fastening hole 33 to prevent it from coming off. The clip member 16 has a plurality of concave grooves 42 extending in the vehicle body longitudinal direction and into which the pipe 13 fits. Here, as an example, four concave grooves 42 arranged in the width direction are formed. At the upper end of each concave groove 42, a return portion 43 that protrudes inward and downward of the concave groove 42 is formed. The return portion 43 flexes when the pipe 13 is inserted, restores when the pipe 13 has passed, and holds the pipe 13 fitted in the concave groove 42.

[0016] FIG. 6 is a view showing the guide member 15 and the clip member 16. A plurality of guide members 15 are connected in the vehicle body longitudinal direction, and clip members 16 are fitted to some of the guide members 15. The guide members 15 are connected for a length corresponding to the total length in the vehicle body longitudinal direction in the section 21. On the other hand, the clip members 16 are arranged at a plurality of positions separated in the vehicle body longitudinal direction in the section 21. That is, the clip members 16 are attached in accordance with the support interval required for the pipe 13. As a working process, first, all the guide members 15 are connected, and the clip members 16 are fitted into the fastening holes 33 at a predetermined interval. Next, the pipe 13 is fitted into the concave grooves 42.

[0017] Then, insert the integrated guide member 15, clip member 16, and pipe 13 into one end of the compartment 21 in the side sill 12. At this time, by inserting the flange portion 32 between the protrusion 22 and the floor surface 24 and between the protrusion 23 and the floor surface 24, the guide member 15 slides along the floor surface 24 of the compartment 21. FIG. 7 is a view showing the in-side-sill fixing structure 14. Here, in the in-side-sill fixing structure 14, a cross-section passing through the center of the nut 34 and along the width direction and the vertical direction is shown as viewed from one side in the vehicle body front-rear direction. After positioning the guide member 15 in the vehicle body front-rear direction, the guide member 15 is fastened to the side sill 12 by fitting the bolt 46 into the nut 34, and the pipe 13 is fixed. The through-hole provided in the lower surface of the side sill 12 for fastening the bolt 46 is, for example, a long hole extending in the vehicle body front-rear direction.

[0018] 《Function and Effect》 Next, the main function and effect of the embodiment will be described. (1) The in-side-sill fixing structure 14 includes the side sill 12, the pipe 13, the guide member 15, and the clip member 16. The side sill 12 forms a closed-section compartment 21 extending in the vehicle body front-rear direction, and protrusions 22 and 23 are formed on the inner peripheral surface of the compartment 21. The pipe 13 extends in the vehicle body front-rear direction and is inserted into the compartment 21. The guide member 15 fits into the protrusions 22 and 23. The clip member 16 fits into the guide member 15 and holds the pipe 13. Thereby, the pipe 13 can be fixed by the guide member 15 and the clip member 16.

[0019] ((ID=2)) A plurality of concave grooves 42 for holding the pipe 13 are formed in the clip member 16. Thereby, a plurality of pipes 13 can be mounted collectively, and the workability is improved. (3) The guide member 15 is provided with a plate portion 31. The plate portion 31 is aligned with the floor surface 24 of the section 21. The plate portion 31 has fastening holes 33 that penetrate in the thickness direction and into which the clip member 16 fits. This makes it easy to attach the clip member 16 to the guide member 15, improving work efficiency. If a variety of clip members 16 with different numbers and sizes of grooves 42 are available, the degree of selection will be increased. (4) The guide member 15 is equipped with a plate portion 31. The plate portion 31 is aligned with the floor surface 24 of the compartment 21. The plate portion 31 is fastened to the side sill 12 by attaching a nut 34 to the nut 34 and fitting a bolt 46 onto the nut 34. This allows the guide member 15 to be firmly fixed to the side sill 12.

[0020] (5) The guide member 15 is configured to be connectable to other guide members 15 in the longitudinal direction of the vehicle body. This allows the guide member 15 to be freely extended in the longitudinal direction of the vehicle body by the number of connections, and enables placement to match the overall length of the side sill 12. Compared to the guide member 15 of the embodiment, this reduces manufacturing costs and makes handling easier than preparing a guide member that is longer in the longitudinal direction of the vehicle body. (6) Multiple guide members 15 are inserted throughout the entire front-rear direction of the vehicle body in the compartment 21. This allows the pipes 13 to be guided well throughout the entire compartment 21 when the pipes 13 are inserted into the compartment 21, improving work efficiency.

[0021] (7) The clip members 16 are arranged at multiple positions within the compartment 21 that are separated in the longitudinal direction of the vehicle body. This allows the clip members 16 to be attached only to the locations necessary to support the piping 13. Compared to the clip members 16 of the embodiment, this configuration reduces manufacturing costs and makes handling easier than a configuration in which longer clip members are prepared in the longitudinal direction of the vehicle body to hold the piping 13 throughout the entire compartment 21. (8) The guide member 15 is formed such that, when viewed from the front-rear direction of the vehicle body, its center in the width direction is separated from the floor surface 24 of the section 21, and only both ends in the width direction are in contact with the floor surface 24 of the section 21. This allows for a snap-in type mounting where the clip member 16 protrudes from the back side of the guide member 15, improving workability.

[0022] (9) The guide member 15 is provided with a plate portion 31. The plate portion 31 is aligned with the floor surface 24 of the compartment 21. The plate portion 31 has a plurality of openings 35 that penetrate in the thickness direction and are arranged along the longitudinal direction of the vehicle body. This makes it possible to reduce manufacturing costs and weight. (10) The projections 22 and 23 are located on both sides in the width direction when viewed from the front-rear direction of the vehicle body. The guide member 15 is fixed by fitting both ends in the width direction when viewed from the front-rear direction of the vehicle body between the projections 22 and 23 and the floor surface 24 of the compartment 21. This allows the guide member 15 to be fixed stably.

[0023] (11) One projection 22 rises from the floor surface 24 of the compartment 21 when viewed from the front-rear direction of the vehicle body, with its tip protruding inward in the width direction. The other projection 23 protrudes inward in the width direction from the side of the compartment 21 when viewed from the front-rear direction of the vehicle body (see Figure 3(a)). This avoids making the width dimension of the guide member 15 unnecessarily large, thereby suppressing an increase in manufacturing costs. (12) The pair of protrusions 22 rise from the floor surface 24 of the compartment 21 when viewed from the front-rear direction of the vehicle body, and their tips protrude inward in the width direction (see Figure 3(b)). This allows for a degree of freedom in the width direction position of the compartment 21 into which the guide member 15 is inserted.

[0024] (13) The pair of protrusions 23 project inward in the width direction from the side of the compartment 21 when viewed from the front-rear direction of the vehicle body (see Figure 3(c)). This maximizes the width dimension of the guide member 15 within the compartment 21 and increases the number of pipes 13 that can be mounted. The protrusion 22 is L-shaped when viewed from the front-rear direction of the vehicle body and requires a widthwise length to press against the flange 32 and a vertical length corresponding to the thickness of the flange 32. In contrast, the protrusion 23 is I-shaped when viewed from the front-rear direction of the vehicle body and requires only a widthwise length to press against the flange 32. Therefore, the protrusion 23 can suppress an increase in manufacturing cost compared to the protrusion 22. (14) The insertion member inserted into compartment 21 is the pipe 13. This allows it to be applied to the various types of piping that the vehicle 11 has.

[0025] Now, let's look at some comparative examples. It is conceivable to route various pipes and wiring through the side sills to protect them from the external environment. However, there has been no proposal for how to specifically secure these routed components, such as pipes and wiring, within the side sills. If the routed components are simply routed through the side sills without being secured, they will move within the side sills due to vibrations of the vehicle body when driving on rough roads such as gravel, bumps, and uneven surfaces. Therefore, there is a possibility that the routed components may interfere with each other or with the side sills themselves.

[0026] Variant form In the embodiment, a configuration in which the pipe 13 is inserted through the side sill 12 has been described, but the invention is not limited to this. Instead of the pipe 13, for example, wiring may be inserted. In other words, any axial member that is long enough to extend along the longitudinal direction of the vehicle body and can be inserted through the side sill 12 can be solid or hollow, and its flexibility does not matter. In the embodiment, a configuration was described in which multiple grooves 42 are formed in the clip member 16 and multiple pipes 13 are mounted on it, but the embodiment is not limited to this. That is, the clip member 16 may have only one groove 42 and only one pipe 13 may be mounted on it.

[0027] Although the above description has been made with reference to a limited number of embodiments, the scope of the rights is not limited to those embodiments, and modifications of the embodiments based on the above disclosure will be obvious to those skilled in the art.
