Description

Description: TECHNICAL FIELD The present invention relates to a two-wheel scooter type vehicle in which an upper portion of a rear wheel is covered with a rear cover.

(Background of the Invention) There is a two-wheel scooter type vehicle having a footrest space that crosses in the left-right direction between a steering bar handle and a driving seat. In this type of vehicle, the upper part of the rear wheel is usually covered with a rear cover. However, in the conventional case, the rear edge of the rear cover is formed in a shape in which a flat plate that is wide in the vehicle width direction is curved along the rear edge, and the taillight is also formed in a flat plate shape at least near the center thereof. Also, the conventional one has a tail light attached to the lower part of the rear edge of the rear cover, and the rear edge of the rear cover is strongly inclined forward above this tail light (usually about 40 to 80 ° with respect to the vertical line).

In this way, when the rear cover is flat and strongly tilted forward above the tail lights, a negative pressure is created in the space from the rear of the driving seat to above the rear edge of the rear cover when driving, and a large turbulence is generated behind this space. appear. Particularly when the flat plate portion at the rear edge of the rear cover is close to the taillight, the negative pressure generated on the flat plate portion easily causes dust and muddy water to be rolled up by the rear wheel to be rolled up above the taillight. Since this turbulent flow is close to the large turbulent flow formed on the back surface of the driver, it is pulled up to a higher position. Therefore, dust and muddy water are likely to adhere to the tail lights and the rear portion of the rear cover. Further, when driving on a bad road, there is a problem that the visibility of the taillight from the rear is deteriorated because dust and muddy water soar to the rear of the taillight.

On the other hand, the tail lamp is required to secure a sufficient area for good rear visibility.

(Object of the Invention) The present invention has been made in view of such circumstances,
Two-wheeled scooter in which dust and muddy water that winds up from the rear wheels do not easily adhere to the rear cover and taillights, and dust that winds up from the rear wheels hides the taillights and reduces the area of the taillights that reduces the visibility of the taillights from behind. The purpose is to provide a model vehicle.

(Structure of the Invention) According to the present invention, the object is to form a footrest space across the vehicle body in the left-right direction between the steering bar handle and the driving seat, and cover the upper side of the rear wheel with the rear cover. In the two-wheeled scooter type vehicle, the two
The rear cover is formed and stands up and the rear cover expands upward and is smoothly continuous on the rear surface of the rear cover, and the rear surface is incorporated into the rear lower part of the rear cover so that the outer surface is continuous with the rear cover. A tail lamp assembly having a substantially triangular shape as viewed from the rear, which has a direction indicator lamp on both sides of the lamp and a reflector plate above the lamp, and the lower edge of the tail lamp assembly is substantially along the lower edge of the rear cover. The upper end is higher than the lower edge of the operation seat, and the rear edges of the rear cover and the tail lamp assembly are formed in a generally arcuate shape in a side view so as to stand upward from the lower part to the upper front. This is achieved by a two-wheel scooter type vehicle characterized in that the surfaces are curved smoothly in a plan view so as to approach each other toward the trailing edge.

That is, by smoothly continuing the rear cover to the rear surface of the backrest which is erected at the rear of the operation seat, the rear edge of the outer surface of the rear cover and tail lamp assembly rises at a steeper angle than the conventional one and flows laterally. The air is smoothly guided to the trailing edge of the outer surface to prevent turbulence from being generated above the tail lights, and to prevent the dust and muddy water from the rear wheels from rolling up above the tail lights. This is to prevent the sticking to the vicinity of the tail light. In addition, while preventing dust from being rolled up in this way, the tail lamp assembly is enlarged and the visibility from the rear of each lamp is increased by utilizing the wide rear cover rear surface that has expanded to the rear surface of the standing backrest, and the tail lamp assembly The rear view has a substantially triangular shape so that the width is narrowed and a sufficient area is secured to maintain high rear visibility.

According to this embodiment, when traveling, the traveling wind blows the rear cover.
It smoothly flows backward along the left and right side surfaces B, B of 62 (Figs. 1 and 4). That is, since the outer surface trailing edge A stands up at a steep angle, and both side surfaces B and B are curved so as to converge toward the trailing edge A, a large negative pressure is generated in the vicinity of the tail lamp assembly 66. The wind does not occur and the running wind smoothly flows behind the entire trailing edge A. Therefore, the dust and muddy water rolled up by the rear wheel 28 are sent rearward by the traveling wind that smoothly flows rearward from the trailing edge A, and the dust and muddy water are less likely to adhere to the tail lamp assembly 66 and the rear cover 62.

Further, since the tail lamp assembly 66 is formed in a substantially triangular shape when viewed from the rear, even if the area of the brake light 68 sandwiched by the left and right direction indicator lights 70 becomes small, a sufficiently large area of the reflector 72 can be secured above it. Here, the rear surface of the rear cover 62 smoothly extends to the rear surface of the backrest portion 56, the lower side of the tail lamp assembly 66 is substantially along the lower edge of the rear cover, and the apex is located above the lower edge of the driving seat 52. The taillight assembly provided here can be upsized. In this way, the area of the tail lamp assembly 66 can be increased, and since the dust that winds up the rear wheels does not easily rise rearward of the tail lamp assembly 66 as described above, the visibility is not deteriorated. Of course, the ratio of the area of the direction indicator light 70, the area of the reflection plate 72, and the area of the braking light 68 can be changed appropriately. In addition, direction indicator light 70 and reflector 72
Is integrally provided on the curved surface in the vicinity of the outer surface rear edge A, so that visibility from the side as well as the rear can be secured,
In particular, the reflector 72 can also have a function as a side reflector. The base plate 66 of the tail lamp assembly 66, which has a substantially triangular shape
Since a has a shape in which the rear portion of the rear cover 62 is cut by a substantially vertical surface, the outer surface of the taillight assembly 66 and the outer surface of the rear cover 62 can be smoothly moved by adjusting the fixing position of the board 66a up and down. It is also possible to obtain the effect of facilitating the alignment of the two.

(Effects of the Invention) As described above, the present invention smoothly connects the rear cover to the rear surface of the backrest that stands up from the rear end of the driver's seat, and places the lower side of the substantially triangular tail lamp assembly near the lower edge of the rear cover. The apex of the seat is located above the lower edge of the driving seat, while the rear edges of the outer surface of the rear cover and tail lamp assembly are raised in a generally arcuate shape, and the left and right side surfaces of the outer surface smoothly approach the rear edge. Since it is curved so that it will be turbulent near the trailing edge. That is, no large negative pressure is generated above the tail lamp assembly. Therefore, dust and muddy water that the rear wheels wind up are less likely to wind up above the taillight assembly, and dust and muddy water are less likely to adhere to the taillight assembly and the rear cover.

Also, the rear wheels do not easily raise dust, and the surface area of the taillight assembly can be significantly increased by using the enlarged rear cover rear surface that extends smoothly to the back of the backrest. Get better In particular, since the reflector plate is provided at the upper center of the tail lamp assembly, it can be made large in size and the rear visibility is further improved. Furthermore, since the left and right side surfaces of the outer surface of the rear cover and tail light assembly are curved smoothly in a plan view so as to approach each other toward the trailing edge, the pair of left and right direction indicator lights has good visibility from the side. Become.
