Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a motorcycle or tricycle equipped with a rear body at the rear of the vehicle body, and more specifically, to a large-capacity helmet storage box that can store a helmet inside the rear body. Regarding the rear body structure that ensures the following.

[Conventional technology]

In conventional motorcycles and tricycles, such as scooters and family bikes, the helmet is hooked to a helmet holder on the vehicle body, but because the helmet is exposed and suspended from the exterior of the vehicle, it is easily soiled by rain and dust. For this reason, a motorcycle as shown in, for example, Japanese Utility Model Application Publication No. 59-26089 has been proposed.

This technology attaches a seat to the vehicle body frame in an openable and closable manner, secures a storage space at the bottom of the seat that is larger than the external contour of the helmet, and creates a roughly hemispherical shape within the storage space whose upper part follows the internal contour of the helmet. A shaped fuel tank is provided, and a helmet is placed over the fuel tank so that the helmet is accommodated under the seat.

[Problem to be solved by the invention]

However, in the above-mentioned helmet storage box, the box-shaped helmet storage box has an upright front wall, so that it may not be possible to accommodate a helmet with a visor, and the opening is also narrow.

The present invention was developed against the background of the above circumstances, and its purpose is to secure a sufficient volume for accommodating a helmet inside the rear body, to absorb traveling vibrations transmitted to the seat, and to make it easy to get on and off the seat. Our objective is to provide motorcycles and tricycles with an easy step-through structure.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention integrates an engine and a transmission mechanism that transmits the output of the engine to the rear wheels in a motorcycle or tricycle that has a rear body at the rear of the vehicle that is continuous with a low step floor. The front end of the powered power unit is pivoted close to the rear end of the step floor, and a helmet storage box is provided inside the rear body above the pivot point, so that the power unit can swing vertically below the helmet storage box. The front wall of the helmet storage box is raised diagonally upward from the pivot point toward the front of the vehicle body and extends above the step floor. It is characterized by having a pivotably supported sheet that covers it so that it can be opened and closed.

[Effect]

The helmet storage box inside the rear body is
Since the power unit is supported by the left and right frame members, the height of the rear body, that is, the seat height, can be suppressed.

Further, since the front wall of the helmet storage box is raised obliquely upward from the rising part of the rear end of the step floor, a large storage volume of the helmet storage box is ensured, and a large opening area can be secured. Furthermore, the front wall, which stands up longer than the upright side, absorbs running vibrations transmitted to the seat.

Furthermore, there is no part of the vehicle body that interferes with the step floor where the rider's legs are placed in front of the helmet storage box, making it possible to create a step-through structure that makes it easy to get on and off the bike.
