Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an improvement in the reinforcing structure of a frame member for a vehicle body, such as a side member of a vehicle body, which has a groove in the longitudinal direction.

(Prior Art) Conventionally, for example, as shown in FIGS. 4 and 5, a side member of a vehicle body has grooves 22 at predetermined locations in a groove 22 of a side member 21 fixed to a panel plate 29. A reinforcing plate (bulk head) 25 for blocking is welded and fixed to the side member 2.
1 deformation is prevented.

(Problem to be Solved by the Invention) However, when installing the electrical wiring 30 in the groove 22 of the side member 21, the through hole 25A must be provided in the reinforcing plate 25, which makes it difficult to work on the electrical wiring 30A. There were flaws.

Therefore, the purpose of the present invention is to solve the above-mentioned drawbacks, and the purpose of the present invention is to prevent deformation due to external forces such as impact, and also to make it easier to conduct electrical wiring by using grooves. The aim is to provide a reinforcing structure.

(Means for solving the problem) The means of the present invention has a groove in the longitudinal direction of a side member, etc., and in the groove of a channel-shaped frame member that is fixed to a panel plate so as to close the groove, A reinforcing member having a width equal to the width of the groove, having an apex in the center, bent into a channel shape in the longitudinal direction, and having a recess on the inside is inserted into the frame member groove on the top side of the reinforcing member, and electrical wiring is inserted thereinto. A reinforcing structure for a frame member for a vehicle body is provided in which a predetermined gap is provided and the reinforcing member is disposed and fixed in the groove so as to close the opening of the reinforcing member recess with the inner bottom surface of the groove or a panel plate.

(Example) Next, the present invention will be explained based on the example shown in FIGS. 1 to 3. In FIGS. 1 to 3, reference numeral 1 denotes a side member having a cross-sectional shape, and is formed by bending a steel plate. 2 is a groove portion of the side member 1, and 3, 3 are fixing pieces of the side member 1 provided on the open 2C side of the groove portion 2. Reference numeral 5 denotes a reinforcing member fixed at a predetermined location in the groove 2 of the side member 1, and in order to provide a gap 4 with a predetermined interval H2 on the upper side or lower side of the groove 2, in this example, on the upper side, the reinforcing member The height of 5 is the depth H of the groove 2
It is formed lower than 1. The reinforcing member 5 is formed by bending a steel plate into a channel shape, and in this example, it has an oblique side plate part 6 extending from the bottom surface 2A of the groove part 2 toward the opening 2C side, and a horizontal part forming a top part from the upper end of the side plate part 6. The provided horizontal plate portion 7 and the horizontal plate portion 7
Vertical side plate portion 8 facing the bottom surface 2A from the rear end
The cross section has a concave portion on the inside, and each side plate portion 6, 8 and horizontal plate portion 7 have a width equal to the width of the groove portion 2, and are each provided with fixing pieces 6A to 8B. 5 is fixed by welding to the bottom surface 2A and both side surfaces 2B, 2B in the groove part 2 by respective fixing pieces 6A to 8B so as to close the opening of the recessed part.

Thus, the side member 1 of this example is fixed by welding the fixing pieces 3, 3 to a predetermined panel plate 9 so as to close the groove 2, and the electrical wiring 10 is inserted into the groove 2 of the side member 1. However, in the side member 1 of this example, the reinforcing member 5 is provided on the bottom 2C side of the groove portion 2, and a gap portion 4 is formed between the horizontal plate portion 7 of the reinforcing member 5 and the panel plate 9 portion corresponding to the horizontal plate portion 7. Therefore, the electrical wiring 10 is conducted through the gap 4. Note that the square-shaped reinforcing member 5 fixed in the groove 2 has fixed pieces 6A to 6B7A, 7A, 8A to 8.
B is fixed to the bottom surface 2A and side surfaces 2B, 2B of the groove portion 2, and is useful for preventing deformation of the side member 1.

Although the reinforcing member 5 in this example has a cross-sectional shape formed by the side plate parts 6, 8 and the horizontal plate part 7, the reinforcing member is not limited to this shape, and is equal to the groove width. In this case, a steel plate is bent in the longitudinal direction into a cross-sectional shape or a ∩ shape, and a channel shape having an apex at the center is adopted. In addition, when the reinforcing member is fixed to the bottom side of the groove with a predetermined gap, the fixing posture of the reinforcing member is to keep a predetermined gap on the bottom side of the frame member groove and close the opening of the reinforcing member recess to the panel plate. The reinforcing member is disposed at the upper end of the groove portion so as to close at the top end thereof, and the reinforcing member of the above-described embodiment is arranged upside down, making it easier to conduct electrical wiring in the gap below the top of the reinforcing member.

(Operations and Effects of the Invention) That is, since the present invention is a means for solving the above-mentioned problems, the intended objectives of the present invention are certainly achieved. That is, in the present invention, the reinforcing member fixed to the groove part naturally prevents deformation due to external forces such as impact, and the reinforcing member in the groove part has a predetermined gap at the bottom or top side of the groove. Since it is fixed in place, electrical wiring becomes easier through this gap, and the workability of electrical wiring can be improved.
