Description

[Detailed Description of the Invention] The present invention relates to a structure around a head pipe in small vehicles such as motorcycles and tricycles.

The present applicant previously provided an automatic tricycle equipped with a motor and having one front wheel and two rear wheels. It is preferable to provide a somewhat large space for storing things in a tricycle, which is such a small vehicle, but since the vehicle is small, it is difficult to do so. It protrudes above the vehicle, which is undesirable in terms of appearance and space utilization. In addition, when wiring harnesses such as control cables such as throttle cables and brake cables, starter circuits, electric cords for headlights and turn signal lamps, etc. around the head pipe that supports the steering part of the front wheels, In order to protect the harnesses and to ensure the movable range of the control cables, special covers, guides, etc. had to be installed separately, which increased the number of parts and made their installation laborious.

The present invention has been made in order to simultaneously solve the disadvantages of forming a storage space in a small vehicle and the disadvantages of harness wiring, and to effectively form both of them. In a small vehicle such as a motorcycle or a tricycle that is equipped with leg shields in front and on the sides of a head pipe that supports the steering portion of a steering wheel, the leg shield is provided with a front box that opens toward the front and a rear box that opens toward the rear. , a back wall of the front box and a back wall of the rear box surround the head pipe, and a box is provided at the center in the vehicle width direction of at least one of the back wall of the front box and the back wall of the rear box that surround the head pipe. By forming an inward recess and providing a storage space for harnesses such as cables and electric cords that communicate in the vertical direction between the recess and the head pipe,
To provide a structure around a head pipe of a small vehicle, which can secure the space necessary for protecting harnesses, especially for movable control cables, while increasing the capacity of a storage space as much as possible.

A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a side view of a tricycle, and FIG. 2 is a front view of the same. Although a tricycle is shown as a small vehicle in the embodiment, the present invention can also be applied to a motorcycle or a motorized four-wheel vehicle.

The tricycle 1 relatively swings up and down (swing motion) between the front body 2 and the rear body 3 by a joint 4.
A leg shield 11, which will be described later, is installed at the forefront of the front body 2, and the leg shield 11
surrounds a steering support section such as a head pipe 2b that supports a steering section consisting of a front wheel 5 and a handle 6, which form one steering wheel. At the rear of the front body 2, a seat post 8 with a seat 7 at the top is installed, the middle part forms a low floor 9, and the rear body 3 has two rear wheels 10 that serve as driving wheels. , 10 are provided.

The leg shield 11 is formed to be slightly wider than the width of the passenger's body, has a front face 11a that is inclined toward the rear, and has a front fender 12 integrally formed from its lower part to side faces 11b, and a rear part 11c that extends from the floor. Consecutive 9.
In addition, a storage recess 13 for a headlight and a turn signal light, which opens forward, is formed in the upper part of the front surface 11a in the width direction.

Next, the structure around the head pipe according to the present invention is shown in the third section.
The description will be made based on FIGS. 6 to 6.

From the front 11a of the leg shield 11 to the side 11
The front box 14, which opens forward from below the storage recess 13 to the front fender 12, is formed in a large concave manner from the bottom to the rear wall 14a of the box 14, as shown in FIGS. 5 and 6.
A sub-frame 15 having a U-shaped cross section is vertically connected to the center portion of the rear width direction with bolts and nuts 16, and U-shaped side pieces 15 of the sub-frame 15
a, 15a are fixed by welding or the like to a head pipe 2b fixed to the front end of the main frame 2a of the front vehicle body 2, whereby the head pipe 2b, which is a steering support part, and the leg shield 11 are integrated.

The opening edge 14b of the front box 14, which is formed wide in the width direction and the vertical direction from the front surface 11a to the side surfaces 11b and 11b of the leg shield 11 as described above, is provided with a lid member 18 which is pivotally attached 17 at the lower end so as to be openable and closable.

Further, behind the back wall 14a of the front box 14, a rear box 19 is formed integrally with the leg shield 11 as shown. The rear wall 19a of the rear box 19 is the same as the rear wall 1 of the front box 14.
It is located on the back side of the main frame 2a and has a rearwardly recessed portion 19b at its center in the width direction, and the recessed portion 19b surrounds these 2a and 2b from the upper part of the main frame 2a along the head pipe 2b. rear box 19
is formed wide, and forms four peripheral walls 19c that bulge out continuously from the back wall 19a toward the passenger side, and a lid member 20 is fitted into the opening edge 19d of the four peripheral walls 19c.

As described above, the area around the head pipe 2b, that is, the leg shield 1 in front of the head pipe 2b in the embodiment is
A front box 14 is formed inside the pipe 2b, and a rear box 19 is formed at the rear including both sides of the pipe 2b.
Furthermore, since both boxes form a large space, they can be effectively used as a storage space, and a storage space that is extremely advantageous in terms of appearance and space utilization can be provided.

Furthermore, according to the present invention, the rear wall 14, which is a partition dividing the front box 14 and the rear box 19,
One of the rear walls 19a and 19a, i.e., the widthwise central portion of the rear wall 19a of the rear box 19, is recessed rearward by a recess 19b, and the recess 19b is formed in the vertical direction while maintaining an appropriate space S around the head pipe 2b. This space S is connected in the vertical direction, and therefore, harnesses 23 such as control cables 21 such as throttle cables and brake cables, and electric cords 22 such as starter circuits, headlights, and turn signal lamps can be wired and stored in the space S.
3 can be protected, and the space required for the movement of the control cables 21 can also be secured.

In the embodiment, one of the back walls 14a and 19a, which is a partition plate, is recessed to form a harness storage space S, and the cross section of the recessed part is shown as U-shaped. It goes without saying that the partition walls 14a and 19a may be recessed, and the cross-sectional shape of the recessed portions can also be set arbitrarily.

As is clear from the above, according to the present invention, the space for harnesses can be partitioned by the back wall of the front box and rear box, which form the storage space, and can be reliably provided around the head pipe. To provide a structure around a head pipe of a small vehicle, which has many advantages such as being able to secure space necessary for protecting harnesses, especially for movable control cables, while increasing the volume inside a formed box as much as possible. Can be done.
