Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a luggage compartment of a motor vehicle adapted to accommodate a spare tire.

[Conventional technology]

In passenger cars, a circular recess is provided in the floorboard of the luggage compartment at the rear of the vehicle body, and the spare tire is stored in this recess. It is now possible to carry . However, since the recess that accommodates the spare tire is press-molded integrally with the floorboard, the peripheral wall of the recess is sloped conically from the bottom of the recess toward the opening edge.

For this reason, if a car is hit from behind and the luggage compartment is crushed forward, the spare tire will pop out of the dent, and even the fuel tank located under the floorboard will be deformed and cracked. There is a risk of fuel leakage. Furthermore, in hatchback-type vehicles, there is a risk of secondary damage such as the spare tire flying out and hitting passengers in the back seat.

[Problem that the invention attempts to solve]

Therefore, the purpose of this invention is to prevent the spare tire from flying out due to such deformation of the vehicle body, and by holding the spare tire inside the recess, the spare tire absorbs the external force caused by the collision, minimizing the deformation of the luggage compartment. The object of the present invention is to provide a structure for an automobile luggage compartment that minimizes the amount of space required.

[Means for solving problems]

In order to achieve the above object, the structure of the present invention is such that at least the front inner circumferential wall of the circular recess for accommodating the spare tire provided on the floor plate of the luggage compartment and the flat part of the floor plate are bent into a V-shaped cross section. This is a combination of stoppers made of folded plates.

[Effect]

The tire stopper 8 moves from the peripheral wall of the depression 7a to the depression 7.
Since the spare tire 10 housed in the space a protrudes upward, even if the luggage compartment is crushed by a rear collision, the spare tire 10 is prevented from flying out, and deformation of the luggage compartment in response to a rear collision is suppressed.

[Example of idea]

To explain the present invention based on an embodiment, as shown in FIG. 1, the floor plate 7 at the rear of the vehicle body has a floor surface that is one step higher than the passenger compartment from a step 7b, and the floor of the luggage compartment Configure. A suspension bar 6 made of a U-shaped plate in cross section and extending laterally is coupled to the front part of the floor plate 7 constituting the luggage compartment, and a rear wheel suspension mechanism is supported by this suspension bar 6. .

A depression 7a surrounded by a conical peripheral wall 15 is formed in the center of the floor of the luggage compartment, and a spare tire 10 is housed in the depression 7a. A flat fuel tank 14 that is elongated in the left-right direction is supported under the floor plate 7 by known means.

The rear end of the floor plate 7 is joined to the rear wall board 3, and this joined part is reinforced by a cross bar 5 to have a box-shaped cross section, and a rear bumper 13 is supported on this reinforced part by suitable means. The upper edge of the rear wall plate 3 is reinforced by a reinforcing panel 4, so that the edge of the trunk lid 1, which is reinforced by the reinforcing plate 2, is supported in the closed state.

A bracket 12 made of an inverted U-shaped plate and fixedly supporting a nut 18 is coupled to the recess 7a. Then, the seat plate 17 is hung over the hole in the wheel disc 16 of the spare tire 10, and the seat plate 1
The tip of a bolt 11 passing through 7 is screwed into the nut to hold the spare tire.

As mentioned above, the peripheral wall 15 of the recess 7a is inclined in a conical shape for press forming.

According to the present invention, in order to prevent the spare tire 10 from jumping out, a tire stopper 8 made of a V-shaped plate is fixed to at least the front portion of the peripheral wall 15 by welding. The tire stopper 8 is connected at one end to the flat portion of the floor plate 7 and at the other end to the peripheral wall 15, and is configured to protrude above the spare tire 10 from the peripheral wall 15.

Preferably, a similar tire stopper 9 is also provided at the rear portion of the peripheral wall 15. The interval between the tire stoppers 8 and 9 is approximately equal to the outer diameter of the spare tire 10, and the spare tire 10 is located at the bottom of the recess 7a.
It is wider than the outer diameter of.

[Effect of idea]

As described above, the present invention includes a stopper made of a plate bent into a V-shaped cross section, at least on the front inner circumferential wall of the circular recess for accommodating a spare tire provided on the floorboard of the luggage compartment and on the flat part of the floorboard. Since we have combined,
Even if the floor plate is deformed due to a rear-end collision with another car and the welded joint of the bracket is separated, the spare tire is prevented from protruding by the tire stopper and is held inside the recess, thereby suppressing the deformation of the floor plate.
At the same time, damage to the fuel tank located under the floorboard is minimized. Therefore, it is possible to prevent fires caused by fuel leaks and injuries to rear passengers caused by the spare tire flying out.

Furthermore, since the rigidity of the floor plate of the luggage compartment against a rear-end collision is reinforced by the spare tire, the strength burden on the side members connected to the lower side edges of the floor plate is reduced, which helps to reduce the weight of the vehicle body.
