Description

Description: TECHNICAL FIELD The present invention relates to a spare tire storage structure and a storage method for an automobile.

2. Description of the Related Art As is well known, in an automobile such as a one-box type vehicle carrying a large number of occupants or carrying relatively large luggage, the body of the same type of vehicle generally depends on the purpose of use of the user. It is required that the height of the floor can be selected as an option.

For this reason, in this type of automobile, generally, two types of so-called flat floor type and low floor type having different floor heights are provided for the same vehicle type. In the flat floor type, the rear wheel tire house is positioned below the vehicle body floor to make the floor surface flat, thereby improving cargo handling. On the other hand, in the low floor type, the rear wheel tire house is Although it protrudes above the floor surface, the boarding floor is set lower than the flat floor type to improve the getting on and off.

By the way, when producing two types of floors of the same vehicle type but different floor heights as described above, it is usually necessary to prepare two types of bodies according to the difference between the types. And recently, in response to diversifying user requirements,
In addition to the above two types, it is considered to add an ultra-low floor type having a lower floor than the low floor type. In this case, three types of bodies are required.

In order to avoid such a problem of increasing the number of types of bodies, for example, it has been considered that a low-floor type and a flat-floor type share a basic body part other than a vehicle body floor part. That is, the above-mentioned low floor type is used as a basic body common to both types, and in response to the requirement of the flat floor type, it is manufactured as a double floor in which a high side floor is disposed above a body floor (low side floor) of the basic body. By doing so, two types, a low floor and a flat floor, can be separately formed with one kind of basic body.

By the way, in the flat floor type vehicle, since the rear wheel tire house needs to be located below the vehicle body floor, the rear wheel tire is usually set smaller than the front wheel tire. That is, since the sizes of the front wheel and the rear wheel are different, it is necessary to provide two types of spare tires, one for the front wheel and one for the rear wheel.

Although the structure for storing the spare tire is not intended to store two types (two) of tires, for example, in Japanese Utility Model Laid-Open Publication No. 1-158380, a tire carrier having a combination of frame members is used. There is disclosed an apparatus that is stored in a suspended state on the lower surface side of a floor.

[Problems to be Solved by the Invention] Generally, as described in detail later, a vehicle is loaded on a vehicle as an angular range for preventing interference between the vehicle body side and a road surface at the time of a vehicle bump on a rough road. A so-called departure angle is set from the contact point between the tire and the road surface at the time to the rear side of the vehicle, and when arranging articles or equipment such as spare tires on the lower surface side of the floor, it is defined by the above departure angle. It is laid out so that it does not fall within the angle range.

However, in a double-floor flat-floor type vehicle manufactured using a low-floor type as a basic body as described above, 2
When two types of spare tires are stored on the lower surface side of the vehicle body floor, the two spare tires are arranged on the lower surface side of the floor for low floor (lower floor). There is a problem that the spare tire cannot be sufficiently secured and the spare tire interferes with an angle range defined by the departure angle.

The present invention has been made in view of the above-described problems, and allows a low-floor type and a flat-floor type to be separately formed with a single basic body, and avoids interference between a spare tire and the angular range of the departure angle.
