Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage device suitable for small vehicles equipped with two front wheels.

Simple two-wheeled vehicles equipped with small, small-displacement motors are generally known. There are two types of two-wheeled vehicles of this type, such as those similar to bicycles and those similar to scooters, but both are two-wheeled vehicles and cannot be operated by those who cannot drive a bicycle.

On the other hand, a tricycle equipped with a prime mover has been proposed and put into practical use as a small vehicle, but such a tricycle is considerably larger overall than a motorcycle or scooter, has a complex structure, is heavy, and has a large displacement of the prime mover. The size of the vehicle also increases accordingly, and it goes beyond the scope of a small, simple vehicle.

Therefore, a three-wheeled or four-wheeled vehicle that can be easily operated even by those who cannot drive a two-wheeled vehicle should be made smaller, lighter, and easier to drive in the same way as a simple two-wheeled vehicle.
The present applicant previously proposed a small-sized traveling vehicle that can be easily operated with the same feeling as a two-wheeled vehicle, and at a cost not much different from that of a two-wheeled vehicle.

It is preferable for the above-mentioned small vehicle to have weather resistance in order to cope with wind and rain, and to achieve this, a windshield device is provided at the front of the vehicle. The windshield device is installed in front of the steering wheel of the vehicle body, and in order to increase the strength and rigidity of the windshield device, reduce wind pressure, and improve comfort, if the cross-sectional plane of the windshield device is made into a U-shape, the front of the windshield and the windshield device are A space is formed between them. On the other hand, small vehicles also require storage compartments, and if possible, it is desirable that the storage compartments be of a closed type and have sufficient capacity.

The present inventor has devised the present invention in order to meet the above demands.

In order to meet the above-mentioned demand, the present invention provides a front wheel steering shaft support member which is provided in an inclined manner toward the rear and upper side of the vehicle body, and in front of which the front wheel steering shaft support member has a substantially U-shaped cross-sectional plane with both sides bent and extended rearward. A cover member is disposed, a headlamp is disposed above the front cover member, and a lower member of the front cover member than the headlight is bulged rearward to form an article storage space; A structural feature is that the rear wall portion of the article storage space is disposed close to the front wheel steering shaft support member.

Therefore, the present invention provides a storage device that can be obtained by using a part of the front cover member without using a special member, that a dead space behind the front cover member can be effectively used, and that the storage device can be provided by using a part of the front cover member. By being provided on the cover member and having a portion thereof bulge out to the rear, it has the advantage that the strength and rigidity of the windshield device including the member can be ensured in a practically necessary and sufficient manner.

Next, to explain its function and effect, when installing the windshield device 16 on the small vehicle, by making the cross-sectional plane approximately U-shaped and installing it in front of the steering wheel, the windshield device 16 is first installed in front of the wind pressure. This system distributes rain to the left and right and guides it to the rear of the sides, preventing wind and rain from getting into the passenger side and reducing resistance to wind pressure.

By tilting the vehicle upward and backward, the wind is guided diagonally upward and rearward behind the left and right side surfaces and along the windshield, reducing resistance and providing good running performance despite having a windshield.

Comfort is improved by bending both sides of the windshield backwards and by providing it in front of the handle, and furthermore, the windshield device is provided in front of the handle and tilts diagonally backward and upward. Therefore, a space is formed between the lower part and the handle, and this space is a dead space, but since this part is used to form the void space integrally with the cover plate as described above, it is extremely effective in terms of space utilization, and it is also sufficient. It is possible to create a storage space. The cover plate forms the base of the lower half of the windshield, and the middle part is concave at the rear, allowing both sides to bend backwards, which significantly improves strength and rigidity. As a result, sufficient strength and rigidity for practical use can be maintained, and the constituent plate materials can be made thinner and lighter.

In addition, the wall of the storage space is attached and supported to the vehicle body side as described above, and since this is a part of the windshield that is formed integrally with the front cover member, it is easy to attach and support the windshield device to the vehicle body. be carried out firmly and reliably. In addition, since the rear wall portion of the article storage space is installed parallel to and close to the front wheel steering shaft support portion, even if this rear wall portion is pushed rearward during loading of luggage, etc. It is not easily bent because it is supported by the front wheel steering shaft support.

Furthermore, the storage space is covered with a lid that forms the trunk lid, which forms a part of the front cover plate, giving it an extremely good appearance.Also, since it can be sealed with a lid as a storage compartment, it is easy to store stored items in the event of rain. It never gets wet.

Furthermore, since the above storage compartment uses a part of the front cover member, there is no need for a separate member, reducing the number of parts.
This is good in terms of cost reduction, and does not require work such as assembling separate parts, and is good in terms of assembly and assembly workability.

In summary, according to the present invention, the dead space of the storage compartment can be effectively utilized, and the strength of the front cover member can be improved.
It can be easily obtained by using a part of the front cover member while improving the rigidity, and has a great practical effect.
