Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear body structure of a motor vehicle, particularly a motor vehicle having a rear door.

In the trunk room formed at the rear of the car,
A conventional method for storing a spare tire is to place the spare tire upright in the back of the trunk (for example, as disclosed in Japanese Utility Model Application Publication No. 118224/1983). However, with the above structure, there was a problem in that it became very difficult to take out the spare tire (especially noticeable in sports type cars).

The present invention has been made in view of the above-mentioned problems, and by adopting a rear body structure that allows the spare tire to be placed as far back as possible, it is possible to make effective use of the trunk space and make it easier to put in and take out the spare tire. The objective is to create a structure that can increase the strength of the rear end panel as well as increase the strength of the rear end panel.

The present invention has a rear door that opens and closes an opening at the rear of the vehicle body; a rear end panel that rises upward from the rear end of the vehicle floor and whose upper portion is bent forward to form a rear opening edge of the rear opening of the vehicle body; a recess formed approximately at the rear center of the vehicle body floor to fit the lower half of the spare tire stored in an upright position below the front bend of the upper part of the rear end panel; A pair of striker towers are vertically fixed to positions on both sides of the striker tower, and a vehicle body-side locking device and a door-side locking device that engage and disengage each other are provided at the upper part of each of the striker towers and on both sides of the rear end of the rear door, respectively. It is characterized by the fact that it is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A rear body structure of an automobile according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

A trunk room 5 is provided at the rear of the vehicle 1 and is surrounded by a vehicle floor 2, a rear end panel 3, and quarter panels 4, 4.

The opening 6 in the upper part of the trunk room 5 is opened and closed by a rear door 7 rotatably supported on the rear end of the roof panel 20. In this embodiment, the rear door 7 is made of transparent glass, but a metal trunk lid may also be used.

The rear end panel 3 rises from the rear end of the vehicle floor 2 and has an upper portion bent forward to form a rear opening edge of the vehicle rear opening 6.
That is, below the front bent portion 3a of the upper part of the rear end panel 3, a space is formed in which the spare tire 8 can be stored in an upright state.

On the other hand, a notch 9 slightly larger than the outer diameter of the spare tire 8 is formed approximately in the center of the rear part of the vehicle body floor 2, and the lower surface of the mouth edge of the notch 9 has a generally semicircular vertical cross-sectional shape. A tire pan 10 is fixed.

Inside the tire pan 10 is a recess 11 into which the lower half of the spare tire 8 is fitted. The spare tire 8 is fitted into the recess 11 and fixed by appropriate fixing means.

Further, a pair of striker towers 12, 12 are fixed in the vertical direction on both sides of the spare tire 8 on the front surface of the rear end panel 3, and a closed cross section is formed between each striker tower 12 and the rear end panel 3. There is.

In this embodiment, the striker tower 1
2 and 12 are installed upright on rear frames 13 and 13 having a closed cross-section structure that are fixed to the lower surface of the vehicle body floor 2 in the front-rear direction, but it is not necessary to have such a structure, and they can be installed in the left-right direction of the vehicle body. It may also be installed upright on the cross member. In the case of this embodiment, the closed cross section of the rear frame 13 and the closed cross section of the striker tower 12 are in a continuous state via the vehicle body floor 2, which greatly contributes to improving the strength.

At the top of each striker tower 12, a hook-type or fork-type vehicle body side locking device 14 is provided.
is provided.

On the other hand, on both sides of the rear end of the rear door 7, strikers 15, 15, which are door-side locking devices that engage and disengage with the vehicle-side locking devices 14, 14, are provided. That is, the rear door 7 is connected to the vehicle body side locking device 1.
It is designed to be closed or opened by engaging and disengaging the strikers 4, 14 and the strikers 15, 15.

In the above structure, each striker tower 12
has the function of receiving the impact when the rear door 7 is opened and closed, and increasing the rigidity of the rear end panel 3 in the vertical and longitudinal directions.

In the drawings, reference numeral 16 is a rear fender, 17 is a lower end panel, 18 is a rain rail, and 19 is a fuel tank.

Next, the effects of the rear body structure of an automobile according to the present invention will be described.

According to the present invention, the rear end panel, which rises upward from the rear end of the vehicle body floor and whose upper part is bent forward to form the rear opening edge of the rear opening of the vehicle body, is placed below the forward bent portion of the upper part of the rear end panel, and approximately at the rear center of the vehicle body floor. Since the spare tire is configured to be stored in an upright position by fitting the lower half of the spare tire into the formed recess, the spare tire can be stored vertically in the rearmost part of the trunk at the rear of the vehicle. This has the effect of making it possible to use trunk space effectively and making it extremely easy to put in and take out the spare tire.

Furthermore, since a pair of striker towers are fixed in the vertical direction on both sides of the spare tire on the front surface of the rear end panel, there is also the effect that the rigidity of the rear end panel in the vertical and longitudinal directions is strengthened.

Furthermore, a vehicle body-side locking device and a door-side locking device that engage and disengage each other are provided at the top of the striker tower and on both sides of the rear end of the rear door, so the force when opening and closing the door can be received by the striker tower. Another advantage is that the fixing strength and durability of the door are significantly improved.
