Description

[Detailed Description of the Invention] The present invention relates to an improvement of a spare tire mounting structure for a vehicle.

As shown in FIG. 1, a spare tire C is stored in the trunk room B of a vehicle A in addition to tools, etc., and the storage and support structure for the spare tire C is conventionally as shown in FIG. 4.

Rear floor panel 5 forming the bottom of the trunk room
1, a trapezoidal support stay 53 is provided on a portion of the recess 52, and a trapezoidal support stay 53 is provided on a portion of the recess 52.
5 is a draw-formed product made of steel plate material as shown in FIG. The support stay 53 is fixed by welding to the top piece 53a of the support stay 53.
Weld the nut 54 to the bottom. Using any of the mounting holes E provided radially in the disk portion D of the spare tire C placed on the recess 52, the bolt 55 having the handle 55a is passed through this hole E and the support stay 5 is attached.
It is inserted and screwed into the nut 54 of the third top piece 53a, and the spare tire C is fixed on the recessed part via the disc part D. The nut 54 is connected to the recess 5 of the rear floor panel 51.
Since it is not directly attached to the top of the panel and the panel is not perforated, rainwater etc. do not enter into the panel or into the nut, which is advantageous in terms of rust prevention. Note that 56 is a cross member provided on the lower surface of the rear floor panel.

The above conventional structure requires a draw-formed support stay, which is troublesome and complicated to form and weld, and it is troublesome to weld a nut to the lower surface of the narrow top piece of the support stay. Improvements are also desired in terms of manufacturing and assembly, such as the need to accurately match the height of the spare tire disc to the height of the spare tire disc.

The present invention was made to improve the above-mentioned problems, and its purpose is to fix a nut on the part of the rear floor panel where the cross member is provided on the lower surface.
The spare tire is fixed with bolts through the spare tire's mounting hole, and the floor panel holes and nuts are covered from the outside with a cross member, making the structure simple, easy to manufacture, and effective while making effective use of parts. To provide a spare tire mounting structure.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a transparent perspective view showing only the main parts of the rear part of the vehicle, where A is the vehicle, B is a trunk room, and C is a spare tire.

A recess 2 for storing a spare tire C is provided in a part of the rear floor panel 1 forming the bottom plate of the trunk room. The width of the spare tire C, that is, the height when it is placed on its side, is equal to or slightly larger than this, and a cover plate (not shown) is placed over the tire C, and the upper surface 1a of the floor panel 1 is
Set it so that it is approximately flat.

A cross member 4 is installed horizontally on a part of the lower surface of the concave bottom plate portion 3 of the floor panel 1. As shown in FIG. The leg pieces 4b, 4b have flange parts 4c, 4c bent outward from the upper ends of the leg pieces 4b, 4b, and the flange part 4
Recesses 4d and 4d are formed on the upper surfaces of the recesses c and 4c, respectively, and these parts are integrally molded. The cross member 4 described above is welded to the lower surface 3a of the concave bottom plate 3 via the flanges 4c, 4c, and a bracket 5 is installed on a part of these parts.
is a small flat piece with long front and rear ends.Both ends of this piece are placed in the recess and spanned between the flange parts 4c, 4c, and these edges are welded. A nut 6 is welded in advance to the bottom surface of the bracket above the groove.
A matching hole 7 that matches the screw hole of the bracket 5 is previously drilled in the bracket 5.

The above cross member 4 has a flange portion 4c,
4c to the lower surface 3a of the bottom plate part 3, the bracket 5 is welded together, and a play hole 8 is bored in the bottom plate part 3, which is concentric with the threaded hole of the nut 6 and the play hole 7 described above. Set up Set the spare tire C on the bottom plate part 3 with the spare tire C facing the recess 2, align any of the mounting holes E of the disc part D with the loose fitting holes 8, and insert the bolts 9 having the grip parts 9a from above into the mounting holes E, It is screwed into the nut 6 through the play holes 8 and 7, and then the bolt 9 is screwed. Even if the bolt 9 is long, since the cross member 4 is groove-shaped, there is sufficient clearance between the nut 6 and the bottom piece 4a, so it will not hit even when tightened, and the reinforcement of the bracket 5 will prevent the bolt from hitting the floor even if tightening force is applied. The concave bottom plate portion 3 of the panel 1 has sufficient strength. The nuts 6 and the holes 7 and 8 provided in the bottom plate and the bracket are covered by the cross member 4 to prevent water and the like from entering these parts, thereby preventing rust.

In the embodiment, the nut 6 is provided below the floor panel, but it may also be provided above.

As is clear from the above, according to the present invention, a nut is attached to the rear floor panel, and the bottom thereof is covered with a cross member, so that the screwed parts such as the nut and the play hole are protected from water and rust is prevented. The structure can be planned using existing cross members, which do not require support stays with complicated shapes as in the past, and are easy to manufacture and construct. Since it is supported by the cross section of the mold, it has many advantages such as superior strength.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; FIG. 1 is a perspective view of the main parts of the rear part of the vehicle, FIG. 2 is a vertical side view of the main parts of the rear floor panel, and FIG. A perspective view of the cross member, FIG. 4 is a view similar to FIG. 2 of the conventional example, and FIG. 5 is a perspective view of the support stay. In the drawings, A is a vehicle, B is a trunk room, C is a spare tire, 1 is a rear floor panel, 3 is a bottom plate portion thereof, 6 is a threaded portion, and 4 is a cross member.
