Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an instrument panel reinforcement which is horizontally mounted inside an instrument panel in a vehicle.

[0002]

[Prior art]

 Conventionally, a vehicle instrument panel reinforcement is used for attaching a steering support or electric components to a hollow reinforcement base 101 welded with pipes and channel members facing each other as shown in FIGS. 6 and 7. The structure is such that a mounting structure 103 for the bracket and the body 102 is provided, and the structure is horizontally mounted inside the instrument panel 104. As is well known, various electric components 105 are arranged in the instrument panel 104, and each of them is connected to a harness 106 arranged on the back side of the instrument panel 104 to supply power.

The wiring of the instrument panel 104 to the electrical equipment 105 is performed by arranging the bound harness 106 along the outer surface of the reinforcement base 101 and branching it at required points to correspond to each. It is connected to the electrical component 105. The instrument panel reinforcement has a welded portion 107 and an edge. In order to prevent the harness 106 from being damaged by these, a corrugated tube or a vinyl pipe is installed in a portion arranged along the instrument panel reinforcement. A protective member (not shown) such as a tube is attached.

[0004]

[Problems to be solved by the device]

 In the conventional instrument panel reinforcement as described above, it is necessary to finish the welded portion 107 and the edge so as not to damage the harness 106 arranged along the same. However, there is a problem in that it requires troublesome consideration for the electric system, such as the need for a protective member, and that the manufacturing process is troublesome and the cost is high. Further, there is a problem caused by arranging the harness 106 along the outer surface of the instrument panel reinforcement. In other words, the bundled harness 106 is difficult to handle, and since it is originally arranged in a narrow space, it is often difficult to arrange the bundled harness 106, and the bundled harness 106 interferes with the defroster nozzle 108 or the like. , It may hit the side defroster duct, which may cause disconnection of the duct joint.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and the purpose thereof is to simplify the wiring of a harness and to consider the external appearance of the electric system, such as the finish of a welded part. Is to provide unnecessary instrument panel reinforcement.

[0006]

[Means for Solving the Problems]

 The instrument panel reinforcement of the present invention for solving the above-mentioned problems is a reinforce having a hollow structure which is formed by joining two members at a mating surface along the longitudinal direction and through which a harness bound inside can be inserted. It is characterized in that a plurality of outlets are provided outside the ment base so that the harnesses arranged in the hollow structure can be branched and can be pulled out to connect to corresponding electrical components.

[0007]

[Action]

 According to the above means, the harnesses bundled with one member of the reinforcement base removed are arranged inside the other member, and the harnesses are connected from the outlets closest to the electrical components on the instrument panel side. It is possible to make an instrument panel reinforcement by joining and fixing one member of the reinforcement base to the other member after branching and pulling out the harness, and wiring the harness inside the hollow structure. Can be made.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, this instrument panel reinforcement 1 is laterally fixed to the body structure 3 at both ends inside the instrument panel 2 of the vehicle, and has a mating surface 4 along the longitudinal direction. The reinforcement body is formed by joining the upper and lower channel members 5, 6. Attachment structures 7 that are integral with or separate from the channel members 5 and 6 are formed at both ends of the reinforcement body, and are fixed to the vehicle body structure 3 by the attachment structure 7. A joining flange 8 is formed on the mating surfaces 4 of the upper and lower channel members 5, 6, and the joining panel 8 is joined and fixed to form an instrument panel reinforcement 1 having a hollow structure over the entire length.

On the mating surface 4 of each of the channel members 5 and 6, a plurality of recesses 10 are formed, each of which serves as a drawer opening 9 that is opened in a circular shape by joining. A plurality of recesses 10 are formed on the mating surface 4 on the instrument panel 2 side, and one is formed on the mating surface 4 on the opposite side, one at each of the left and right ends. As shown in FIG. 5, a burring-shaped guide opening 11 is formed on the outer edge of each recess 10. The plurality of recesses 10 on the mating surface 4 on the instrument panel 2 side are preset so that the positions thereof substantially correspond to the positions of various kinds of electrical components 12 arranged on the instrument panel 2.

This instrument panel reinforcement 1 has a structure in which a lower channel member 6 is first attached to both ends of a vehicle body structure 3 with a mating surface 4 facing upwards by a bolt / nut 13 or the like. After fixing in a rack shape, the upper channel member 5 is faced downward to join the joining flanges 8 of the mating surfaces 4 to each other, and the joining flanges 8 are fixed to each other with a rivet 14 or the like. Is also assembled by fixing it to the body structure 3 at both ends.

At this time, the harness 15 is routed before the upper channel member 5 is joined. That is, the harness 15 that is pulled in from the engine room side to the inside of the vehicle and bundled into a large number is bundled into a single harness 15 through the side recessed portion 10 formed in the mating surface 4 on the engine room side. It is housed in the channel of and is routed. Subsequently, the bound harness 15 is branched from the concave portion 10 closest to each electric component 12 and pulled out to the outside, and the upper channel member 5 is joined and fixed as described above. As a result, the harness 15 is arranged in the hollow portion of the instrument panel reinforcement 1, and the electrical components 12 arranged on the instrument panel 2 are connected by the harnesses 15 drawn out from the outlets 9. It will be. As shown in FIG. 5, each outlet 9 is formed with a guide port 11 so that the harness 15 is not damaged.

As a result, not only the finishing work of the welded portions and edges of the outer surface of the instrument panel reinforcement 1 becomes unnecessary, but also the protective member such as the corrugated tube for covering the harness 15 becomes unnecessary. Further, the wiring of the harness 15 is facilitated, and since the bound harness 15 is not exposed to the outside, the defroster nozzle, the defroster duct, and the like do not interfere with the harness 15 and the electrical components 12 It is also possible to install the harness 15 at the shortest distance.

[0013]

[Effect of device]

 According to the present invention, as is clear from the above description of the embodiments, the harnesses bound together with one member of the reinforcement base removed are routed inside the other member, and the electrical components on the instrument panel side are arranged. It is possible to construct an instrument panel reinforcement by branching and pulling out each harness from the nearest outlet to each part and then joining and fixing one member of the reinforcement base to the other. Since the harness can be routed inside the hollow structure, finishing work on the outer welds and edges is unnecessary, and the protective members such as corrugated tubes that have covered the harness are also unnecessary, resulting in cost reduction. Reduce. In addition, the harness does not interfere with the defroster nozzle, the defroster duct, etc., which simplifies the wiring work of the harness and allows the electrical components to be connected with the harness at the shortest distance.
