BACKGROUND OF THE INVENTION This invention relates to a cab floor reinforcement.

[0002]

2. Description of the Related Art In order to partially reinforce a cab floor from the back side, a reinforcement is attached to a floor panel. Of these, a portion near a front portion of a seat mounting position crosses in a vehicle width direction as shown in FIG. The reinforcement 1 is connected to the floor panel 2 by spot welding at both ends (flanges) of a hat-shaped cross section. A weld nut is fixed to the center of the force 1 section, and the radiator cover 4
Mounting plate 5 is bolted. The mounting plate 5 is extended so that the rear end side projects from the center of the force 1, and also serves as a holding portion 6 (retainer) for holding the insulator 3 of the engine room between the floor panel 2 and the floor panel 2.

The mounting plate 5 has both side edges including the holding portion 6 of the insulator 3 bent in a U-shape so that the radiator cover 4 (attached to the front inclined surface 7 with a clip) and the insulator 3 are not damaged. Has become. Reference numeral 8 denotes a center sheet in the cab, and its legs are bolted to a weld nut 9 fixed to the back surface of the floor panel 2. Reference numeral 10 denotes a radiator.

[0004]

In the prior art, since the reinforcement 1 merely functions to reinforce the floor panel 2, the mounting plate 5 of the radiator cover 4 and the like are individually arranged around the reinforcement 1. It has to be retrofitted, so that the number of parts is increased and there is a problem in terms of cost and weight.

The purpose of the present invention is to increase the functionality of the reinforcement in order to solve such problems.

[0006]

Therefore, in a reinforcement for reinforcing a cab floor panel from the back side, a weld nut for fastening a leg portion of a center sheet to the floor panel is fixed to an inner surface of a central portion of the groove shape in cross section. One side of the force cross section extends obliquely to the upper part of the radiator, and the other side is folded outward at a substantially right angle to the mounting part of the radiator cover. Form.

[0007]

The reinforce is formed by abutting the central portion of the cross-sectional groove shape on the back surface of the floor panel, that is, in a mounting state in which the conventional hat-shaped cross-section is turned upside down. The function of attaching the insulator and the function of coupling with the center sheet are further achieved by the weld nut on the inner surface of the central portion. Therefore, it is not necessary to separately arrange a mounting plate for the radiator cover and a weld nut for coupling the center sheet of the floor panel, and the number of these components around the reinforcement can be reduced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 20 denotes a cab floor panel, reference numeral 21 denotes a reinforce which crosses the vicinity of the front of the seat mounting position in the vehicle width direction, and reinforce 21 denotes a center seat on the inner surface of a groove-shaped cross section. A weld nut 23 for fastening the legs of the base 22 to the floor panel 20 is fixed, and one side of the cross section of the force 21 is obliquely extended to the upper part of a radiator (not shown) to be attached to the mounting part 21a of the radiator cover 24 and the other side. Is folded outward at a substantially right angle, and the insulator 25 in the engine room is connected to the floor panel 2.
0 is formed on each of the holding portions 21b sandwiched between the holding portions 21b. In addition, the attachment part 21a of the radiator cover 24 and the holding | maintenance part 21b of the insulator 25 each have an edge part bent like a U shape like the former.

The reinforcement 21 is joined by spot welding in a mounting state in which the center of the cross-sectional groove shape abuts against the back surface of the floor panel 20, that is, the conventional hat-shaped cross-section is turned upside down. The leg of the center sheet 22 is fastened to the floor panel 20 by bolts with the weld nut 23 at the center. Force 2
A radiator cover 24 is provided on one side (inclined surface) of one cross-sectional shape.
Is attached with a clip, and the insulator 25 is similarly sandwiched between the other side and the floor panel 20.

[0010] With such a configuration, the reinforcement 2
1 has a function of attaching the radiator cover 24 and the insulator 25 by its cross-sectional shape, and a function of connecting to the center sheet 22 by the weld nut 23 on the inner surface of the central portion. There is no need to separately arrange a weld nut or the like for joining the sheets,
The number of these surrounding parts can be reduced. Also,
The reinforcement 21 is integrally fastened to the floor panel 20 together with the leg portion of the center sheet 22 by the weld nut 23 at the center. Therefore, even if the number of spot welding points with the floor panel 20 is reduced, a good connection state is obtained. It can be secured.

[0011]

In summary, according to the present invention, a weld nut for fastening the leg of the center sheet to the floor panel is fixed to the inner surface of the central portion of the groove shape in the reinforcement for reinforcing the cab floor panel from the back side. On the other hand, one side of the force cross section extends obliquely to the upper part of the radiator, and the other side is folded outward at a substantially right angle to the mounting part of the radiator cover. Since there is no need to separately arrange a radiator cover mounting plate and weld nuts for connecting the center sheet as before, it is possible to reduce the number of these components around the reinforcement, which reduces weight and cost. The advantage is obtained.
