Description

Straddle vehicle

The present invention relates to a straddle-type vehicle, in particular to the structure of the rear light unit and the rear body shell of the straddle-type vehicle.

Previously, there has been known a straddle-type vehicle having an integrated taillight unit protruding from the rear body shell.

For example, in the straddle-type vehicle of Patent Document 1, the integrated tail light unit is arranged in the rear body shell provided at the rear of the body, and the part of the light-transmitting cover protrudes from the rear body shell. The so-called integrated taillight unit means that the taillight part and the brake light part are integrated and covered by a transparent cover. In addition, the same lamps are used for the taillights and brake lights, which are used as taillights during normal driving, and used as brake lights when the brakes are operated, with brighter brightness.

In addition, the left blinker portion and the right blinker portion in Patent Document 1 are respectively arranged on both sides of the tail light unit when viewed from the rear of the vehicle.

[Prior Technical Literature]

Patent Document 1: Japanese Patent Application Publication No. 2005-119570

However, in the vehicle of Patent Document 1, the light-transmitting cover protrudes from the rear car body shell. The light-transmitting cover allows the light of the tail lamp unit to pass. Because part of the light is refracted, reflected, or scattered by the light-transmitting cover, even in the lamp There is a reflective member that guides the light to the rear of the vehicle around it, but it is still unable to suppress the scattering of light toward the outer periphery of the tail light unit. Therefore, the actual luminous range of the tail light unit under the rear view of the vehicle will be larger than the area of the light-transmitting cover under the rear view of the vehicle. And because the brightness of the brake light is equivalent to the maximum brightness of the tail light unit, the light-emitting range is expanded more significantly when the brake is operated.

In addition, in Patent Document 1, there is no structure to separate the tail light unit and the left and right blinker portions arranged on both sides, and the brightness when the blinker portion is turned on and when the brake light portion is turned on The brightness is almost the same, so there is the possibility of mutual interference due to the expansion of each other's luminous range.

For example, during the period when the direction indicator light is on, when the brake light portion is turned on due to the operation of the brake, the strong light from the brake light portion will be scattered to the light-emitting range of the direction indicator light under the rear view of the vehicle, which will cause interference. Interference in the blinker section. Or while the brake light is on, when the blinker is turned on to notify the driver behind to turn, the strong light from the blinker will be scattered to the light-emitting range of the tail light unit under the rear view of the vehicle. This will cause interference to the brake lights.

The present invention was made in view of the above-mentioned situation, and its object is to provide a straddle seat type with high discrimination between the light-emitting range of the brake lamp and the blinker even if the brake lamp and the blinker are turned on at the same time vehicle.

In order to improve the recognition of the light-emitting range of the brake light part under the rear view of the vehicle, the inventor of the present invention first thought of accommodating the tail light unit in the rear so that the transparent cover of the integrated tail light unit does not protrude from the rear body shell. Inside the car body shell.

Thereby, mutual interference can be avoided when the direction indicator part and the brake light part are turned on at the same time. However, other parts such as a storage box or a seat locking device are also arranged inside the rear body shell, so space is limited. If the tail light unit is to be completely contained in the rear car body shell, the rear car body shell may become larger, and the shape of the vehicle will also become larger, which will deteriorate the mobility of the vehicle.

In addition, considering the comfort of the driver's feet, the size of the vehicle in the vertical direction is not suitable for enlargement. Therefore, the taillights and direction indicators cannot move further away in the up and down direction. In addition, there is also a method of increasing the distance between the tail light unit and the blinker portion in the left-right direction. However, this will increase the size of the vehicle in the left-right direction and deteriorate the vehicle's maneuverability.

Under such circumstances, the inventor of the present case focused on the relationship between the intensity of the light of the taillight unit and the intensity of the light of the brake light, which is quite weak, and studied the internal structure of the taillight unit in order to achieve a better effect of the light of the brake light. Improved recognition.

First of all, the inventor of the present case changed the integrated tail light unit, divided it into the lighting area of the tail light and the brake light, and arranged the brake light in the center of the left and right directions, so that the brake light and the direction indicator light were exhausted. Possibly separate configurations to reduce the degree of mutual interference.

In addition, a diffusing member is added to the tail light portion, and the diffusing member is arranged to separate the brake light portion and the direction indicator light portion from the rear view of the vehicle. The diffusion member can not only prevent the shape of the internal lamp from showing and make the brightness uniform, but also has the effect of reducing the light transmittance. Therefore, after adding a diffuser to the tail light, the tail light will become darker and maintain uniform brightness.

By configuring a diffuser that can make the outer periphery of the tail light unit darker and maintain uniform brightness, compared with the previous integrated tail light unit, the light emitting range of the tail light unit can be more concentrated. As a result, even if the brightness of the brake light section is the same as the brightness when the direction indicator light section is turned on, the rear light section with a relatively low brightness and a relatively concentrated luminous range is separated between the two, and the brake light section can be improved. Recognition of the luminous range when the direction indicator lights up at the same time Sex.

On the other hand, the brightness of the tail light section with the diffusion member is considerably lower than that of the blinker section. When the blinker section is turned on, the recognition of the tail light section may be reduced. In this regard, the inventor of the present case conducted a further review, and finally developed a new method of specially designing the shape of the rear car body shell while simultaneously solving the above-mentioned problems. The following describes the composition of the invention obtained by the inventors after conducting various reviews and researches.

The straddle-type vehicle of the first embodiment of the present invention is characterized by having: a rear body shell arranged at the rear of the body, a tail light unit arranged on the rear body shell, and a rear light unit arranged on the rear body shell and located at a relatively high level. The left blinker part on the far left of the tail light unit, and the right blinker part arranged on the rear body shell and located further to the right of the tail light unit; the tail light unit includes: arranged in the center of the left and right directions and accompanied The brake light part that is lit by the brake operation, the tail light part that can be turned on when driving, the base that holds the brake light part and the tail light part, and is arranged behind the base, and is a different entity from the base The translucent cover; the translucent cover has a light irradiating surface that allows the light emitted from the brake light portion and the tail light portion to pass toward the exterior of the vehicle body; the tail light portion has a rear view of the vehicle at least disposed on the brake light portion and The left diffusing member between the left blinker portion, and the right diffusing member disposed at least between the brake light portion and the right blinker portion; the rear car body shell is provided with at least a part of the tail light unit Tail light unit accommodating portion; the tail light unit accommodating portion has a peripheral wall portion that protrudes toward the rear with respect to the surface of the rear body shell and is continuously formed at least on the left, above, and right of the tail light unit; the peripheral wall portion is at least arranged In the position separating the left diffusing member and the left blinker portion, and the position separating the right diffusing member and the right blinker portion, and when viewed from the side of the vehicle, it is more than the left blinker portion and the right blinker portion. Each rear end of the blinker portion protrudes further toward the rear, and shields the light irradiated surface when viewed from the side of the vehicle.

According to the first embodiment of the present invention described above, the brake light unit is arranged in the center in the left-right direction, which not only suppresses the enlargement of the rear part of the vehicle, but also separates the brake light unit and the blinker light unit as much as possible, thereby greatly increasing To reduce the degree of mutual interference when lighting up.

In addition, the tail light part has a left diffusion member arranged at least between the brake light part and the left blinker part, and a right diffusion member arranged at least between the brake light part and the right blinker part in a rear view of the vehicle. In this way, even if the brightness of the brake light part is on and the brightness of the direction indicator part are almost the same, because the two are separated by the darker and clearly concentrated tail light part, the brake light can be improved. The recognizability of the light-emitting range when the part and the direction indicator light part at the same time

In addition, the tail light unit accommodating portion has a peripheral wall portion that protrudes toward the rear with respect to the surface of the rear car body shell and is continuously formed at least to the left, above, and right of the tail light unit, and the peripheral wall portion is arranged at least to separate the left diffusion member and The position of the left blinker part and the position separating the right diffuser and the right blinker part, and when viewed from the side of the vehicle, protrude further toward the rear than the rear end of each of the left blinker part and the right blinker part, And shield the light irradiated surface from the side view of the vehicle. With this peripheral wall, even if the direction indicator lights on the left and right sides are lit, or there is stray light from street lights, etc. from above the straddle-type vehicle, it is difficult for these lights to enter the rear light unit accommodating part, so in the tail light unit A "dark zone" is formed in the containment area. The diffuser of the tail light is located in this "dark area", so even if the brightness of the tail light is low when it is lit, it can be easily seen.

Especially when viewed from the side of the vehicle, the peripheral wall not only shields the diffuser of the taillight, but also shields the light irradiated surface of the translucent cover through which the light from the taillight unit passes. Therefore, the translucent cover refracts, reflects, or scatters. The light cannot be scattered toward the outer periphery of the tail light unit. As a result, the light-emitting range of the taillight unit under the rear view of the vehicle is roughly the same as the area of the light-transmitting cover under the rear view of the vehicle, and will not be interfered by the light from the left and right direction indicator lights, so the light-emitting range of the taillight can be increased 的identification.

Therefore, according to the above-mentioned first embodiment of the present invention, it is possible to provide a method of suppressing the enlargement of the rear part of the vehicle, so as to improve the recognition of the light-emitting range of the brake light part and the direction indicator part, and the recognition of the light-emitting range of the tail light part respectively.
