1 is a schematic perspective view of the roof rack 1000 provided in the vehicle C. As shown in FIG. FIG. 2 is a schematic exploded view of the roof rack 1000 of FIG. 1. FIG. 3 is a schematic rear view of the roof rail 100 of FIG. 2. 4 is a schematic cross-sectional view of the roof rail 100 along the line AA ′ of FIG. 2. 5 is a schematic perspective view of the resin insert 130.

1 to 5, the roof rack 1000 is mounted on the roof panel RP of the vehicle C in the longitudinal direction of the vehicle C in order to load an object on the upper portion of the vehicle C. It is a structure to be mounted. The roof rack 1000 includes a roof rail 100 and a roof pad 200.

The roof rail 100 may be made of a plastic material. Roof rail 100 is made of a plastic material, there is an advantage that can be lightweight compared to the conventional roof rail of aluminum material. Roof rail 100, as well as made of a plastic material, by having a groove (G), there is an advantage that can be reduced in weight compared to the conventional roof rail of aluminum material.

The roof rail 100 includes a resin structure RS having a groove G on one surface. The groove G may be, for example, a "U" shaped groove G. In the groove G, resin ribs 111 are provided. The resin ribs 111 may be made of plastic. The resin ribs 111 may serve to reinforce the rigidity of the roof rail 100.

The resin ribs 111 extend from one surface of the roof rail 100 and protrude from one surface of the roof rail 100. The resin ribs 111 may be connected to each other to partition a space in the groove G. In the groove G, rib patterns 110 are included, and the rib patterns 110 are divided into resin ribs 111 connected to each other and sub-grooves partitioned by resin ribs 111 connected to each other. (112).

At least some of the sub-grooves 112 may be isolated from each other by the resin ribs 111 connected to each other and may not be connected to each other. In other words, at least some of the sub-grooves 112 may form an island pattern.

The sub-grooves 112 may be formed in various sizes and are not necessarily designed to be the same volume. For example, the resin ribs 111 may be designed in a grid pattern.

In the groove G, the resin partitions 120 are disposed. The resin partitions 120 are disposed between the rib patterns 110. The rib patterns 110 and the resin partitions 120 may be alternately disposed in the longitudinal direction of the roof rail 100, that is, in the longitudinal direction of the vehicle C. The resin partitions 120 may be made of a plastic material.

The resin barrier ribs 120 are filled with resin, and there are no empty spaces in the inner regions of the resin barrier ribs 120. For example, the thickness t2 of the resin partitions 120 may be in a range of 0.1 mm or more and 50.0 mm or less. At least some of the resin inserts 130 are inserted into the resin partitions 120. Although not shown, a portion of the resin inserts 130 may be inserted into the resin partitions 120, and another portion of the resin inserts 130 may be exposed to the outside from the resin partitions 120. . The inner surfaces of the resin partitions 120 are in direct contact with the outer surfaces of at least some of the resin inserts 130. The roof rail 100 may be manufactured by injection molding, and the resin inserts 130 may be inserted into the resin partitions 120 through insert injection molding.

The resin inserts 130 may serve to make the thickness t2 of the resin partitions 120 uniform.

For example, the resin inserts 130 may be composed of a first part and a second part extending from the first part. The first part may have a larger volume than the second part. In detail, at the connection part at which the first part and the second part are connected, the first part may have a larger area than the second part. For example, the first part and the second part may be designed to have a substantially rectangular pillar shape. However, it is a matter of course that the shape of the first part and the second part is not limited only to the rectangular pillar shape shown. At least one through hole TH may be formed in the first part.

The through hole TH is a space into which at least one sub-partition wall (see 150 in FIG. 6) is inserted, which will be described later in FIG. 6, and the roof rail 100 includes at least one sub-partition wall (150 in FIG. 6). By being inserted into at least one through hole TH of the resin inserts 130 to be connected to at least one of the resin ribs 111, the resin inserts 130 may have improved rigidity against external impact.

As described above, the roof rail 100 may be manufactured by injection molding. The plastic molded part is spontaneously contracted in the cooling process after injection molding at a high temperature, where the uneven thickness causes a difference in cooling rate, and causes a sink mark on the surface of the plastic molded part. to be.

In the case where the resin inserts 130 are not inserted into the resin partition walls 120, the resin partitions 120 include a longitudinal cross section of the shaft rod 141 as compared with a first cross section R1 including a longitudinal cross section of the shaft rod 141. The second end surface R2 not to have a thick resin region.

In other words, when the resin inserts 130 are not present, that is, when only the fastening members 140 are inserted into the resin partitions 120, the insertion region R1 into which the fastening members 120 are inserted and In the non-insertion area R2 in which the fastening member is not inserted, thickness deviation of the fastening members 120 inserted into the resin partition walls 120 may occur.

Due to this thickness nonuniformity, a sink mark may be generated on the outer surface of the roof rail 100.

On the other hand, when the resin inserts 130 are inserted into the resin partitions 120, the thickness t2 of the resin partitions 120 may be uniformly formed, and as a result, the resin inserts 130 may be formed. Silver has an advantage that can improve the appearance quality of the roof rail (100).

Fastening members 140 are inserted into the resin inserts 130. The fastening members 140 are inserted into the resin inserts 130 by insert injection molding. An outer surface of at least a portion of the fastening members 130 may be disposed in direct contact with the inner surfaces of the resin inserts 130. The inner surfaces of the resin inserts 130 are designed to directly contact the outer surfaces of at least some of the fastening members 140, so that the roof rail 100 may secure rigidity.

The thickness t1 of the resin inserts 130 may be thicker than the thickness t2 of the resin partitions 120. The volume of the resin inserts 130 may be larger than the volume of the resin partitions 120.

The fastening member 140 may be formed of, for example, a metal material or a plastic material.

A part of the fastening member 140 is inserted into the resin insert 130 and the other part of the fastening member 140 is exposed to the outside from the resin insert 130.

The fastening member 140 may include a shaft rod 141, a head 142 disposed at one end region of the shaft rod 141, and a screw line 143 provided at the other end region of the shaft rod 141. A portion of the rod 141 and all of the head 142 are disposed to be inserted into the resin insert 130, and at least a portion of the thread 143 is exposed to the outside from the resin insert 130. However, as shown in FIG. 3, the arrangement of the thread 143 is not limited, and although not illustrated, all of the thread 143 may be exposed to the outside from the resin insert 130.

Although not shown, the shaft 141 may be designed in various shapes such as a polygonal column, a circular column, an elliptic column, and the like. The shaft bar 141 may have a thickness within a range of, for example, 4 mm or more and 8 mm or less. For example, when the shaft bar 141 has a circular columnar shape, the diameter of the shaft bar 141 may be 4 mm or more and within a range of 8 mm or less.

The roof rail 100 may be made of a first resin. In detail, the resin structure RS, the resin ribs 111, and the resin partition walls 120 may be formed of a first resin. In this case, the resin inserts 130 may be made of a first resin.

For example, the first resin may be composed of fiber reinforced plastics. Fiber-reinforced plastics, the reinforcing fibers are added to the base resin, for example, a polyester resin, polyamide resin, nylon resin and the like can be used as the base resin. As the reinforcing fibers, for example, carbon fibers and / or glass fibers may be used.

Fiber reinforced plastics are, for example, glass fiber reinforced plastic, carbon fiber reinforced plastic, continuous fiber reinforced plastic, continuous glass fiber reinforced plastic, continuous carbon fiber reinforced plastic, short fiber reinforced plastic, short glass fiber reinforced plastic, short carbon fiber Reinforced plastics, long fiber reinforced plastics, glass long fiber reinforced plastics, short glass fiber reinforced plastics, and the like.

For example, the first resin may be composed of nylon-based fiber reinforced plastics. Nylon fiber-reinforced plastics include nylon resin and reinforcing fibers.

Nylon-based fiber reinforced plastic, for example, may be composed of 50% by weight to 70% by weight of nylon 6 and 30% by weight to 50% by weight of mineral glass fiber (MGF). Nylon-based fiber reinforced plastic, for example, may be composed of 60% by weight of nylon 6 and 40% by weight of mineral glass fiber (MGF). Nylon-based fiber reinforced plastic, for example, may be composed of 40% to 60% by weight of nylon 6 and 40% to 60% by weight of glass fiber (GF). Nylon-based fiber reinforced plastic, for example, may be composed of 50% by weight of nylon 6 and 50% by weight of glass fiber (GF).

On the other hand, the roof rail 100 may be composed of a first resin. In detail, the resin structure RS, the resin ribs 111, and the resin partition walls 120 may be formed of a first resin. In this case, the resin inserts 130 may be made of a second resin different from the first resin.

For example, the first resin may be composed of fiber reinforced plastics. The fiber reinforced plastics are as described above. The second resin can be, for example, a non-foamed plastic.

The second resin can be, for example, foamed plastic. The foamed plastic may play a role of lightening the roof rail 100. Foamed plastics can be, for example, polyurethane foams, polystyrene foams, polyolefin foams, phenolic resin foams, polyvinyl chloride foams, polyimide foams, and the like. For example, the second resin can be composed of polyurethane foam.

The roof pad 200 may be made of a plastic material. The roof pad 200 may be made of, for example, polyester resin, polyamide resin, polyolefin resin, fiber reinforced plastic, or the like. However, since the roof pad 200 does not directly support the load of the loaded cargo unlike the roof rail 100, since the high rigidity is not required as compared with the roof rail 100, the roof pad 200 is more rigid than the roof rail 100. It may be composed of this weak material.

The roof pad 200 may include a frame body 210, through holes 220 passing through the frame body 210, and fastening holes 230 disposed between the through holes 220. The roof pad 200 may be coupled to the roof rail 100 by inserting the fastening members 140 into the fastening holes 230.

The fastening holes 230 and the through holes 220 may be disposed along the length direction of the roof pad 200, that is, along the length direction of the vehicle C. At least one through hole 220 may be disposed between the fastening holes 230.

The at least one sub-bulb 150 may be inserted into the through hole TH of the resin inserts 130 and may be connected to at least one of the resin ribs 111. Stiffness against external impact can be improved.

Two or more of the resin ribs 111, the resin partitions 120, and the at least one sub-bulb 150 may be made of a first resin. In this case, the resin inserts 130 may be made of a first resin.

For example, the first resin may be composed of fiber reinforced plastics. For example, the first resin may be composed of nylon-based fiber reinforced plastics. The fiber reinforced plastics and nylon-based fiber reinforced plastics are as described above.

For example, the resin ribs 111, the resin partitions 120, and the resin inserts 130 may be made of the first resin. For example, the resin ribs 111, the at least one sub-bulb 150, and the resin inserts 130 may all be made of the first resin. For example, the resin partitions 111, the at least one sub-partition 150, and the resin inserts 130 may all be made of the first resin.
