Description

Turn signal lights on the floor}

The present invention relates to a floor direction indicator lamp, and more particularly, by irradiating a predetermined light on a road so as to perform highly visible direction indication in small vehicles such as personal mobility, direction confirmation even at a distance from the personal mobility It relates to a floor direction indicator lamp configured to enable this.

Displaying turn indicators while driving is essential to prevent accidents, and the Road Traffic Act imposes fines for 'unlit turn indicators' when changing lanes or turning left/right without operating turn indicators.

Personal mobility such as bicycles are allowed to run in some lanes, and although there are differences depending on the standard, it is sometimes treated as a 'vehicle', but it is not compulsory to install separate turn indicators.

In order to improve the above problems, technologies for attaching predetermined small turn indicators to positions such as helmets, vests, handles, taillights, etc. have been proposed.

Korean Patent Publication No. 10-2020-0102569 discloses a "direction indicating device for a bicycle". The above patent document proposes a turn signal lamp attached to the handle, but in the case of a turn indicator lamp attached to the end of the handle, there is a high possibility that the direction indicator lamp will be covered by a cyclist's body, etc. There are limitations that are difficult to ascertain.

The problem to be solved by the present invention is to improve the limitations of the conventional turn indicators for personal mobility (bicycles, etc.) It is to provide a floor direction indicator in the form of irradiating.

The present invention is provided on both sides of the personal mobility, in order to improve the limitations of the conventional direction indicators for personal mobility (bicycles, etc.) as described above, to radiate a predetermined light to the ground for direction direction indicator lamps; a direction input unit that is operated to blink one of the direction indicator lamps on both sides to indicate a direction; and a control unit that, when the direction input unit is manipulated, blinks the direction indicator lamps for a predetermined period of time and then turns them off again, wherein the direction indicator lamps are: an image projected backward based on the traveling direction of the personal mobility. When the lower width of is defined as 1 standard size, an image of an asymmetrical shape is irradiated to the ground so that the upper width of the image irradiated forward is 3 to 5 standard size based on the direction of travel of the personal mobility, and the personal mobility From the inner end of the image irradiated at a location close to the body with respect to the body to the outer end of the image irradiated at a location far from the body based on the personal mobility body, the image is sequentially expanded and irradiated, providing floor direction indicators do.

In addition, it accommodates the direction indicator lamp and is fixed to both sides of the personal mobility at an angle of 45 to 60 degrees with respect to the ground while facing the side and rear based on the traveling direction of the personal mobility. a light-collecting reflector that performs a reflective function; an auxiliary lamp for radiating predetermined light toward the light collecting reflector; and an illuminance sensor provided on one side of the personal mobility and measuring the illuminance of a space where the personal mobility is located, wherein the control unit: when the illuminance measured by the illuminance sensor is equal to or greater than a predetermined value, the direction indicator lamp When the auxiliary lamp is turned on at the same time as the blinking time, and the personal mobility is located in a space with a predetermined illuminance or more: While radiating the direction indicator lamp to the ground, the light and direction emitted from the auxiliary lamp through the light collecting reflector It is possible to assist in confirming the driving direction of the personal mobility from the side and rear by illuminating the light scattered outward from the indicator lamp to the side and the rear.

And, a navigation provided in the personal mobility to guide a driving route; and an angle sensor provided on a steering wheel of the personal mobility, wherein the direction input unit: learns the angle of the steering wheel while the personal mobility travels along a predetermined path along the navigation, and detects lane change, left turn, and right turn. An angle learning module for determining a steering wheel angle change in the case of a straight ahead angle, determining a steering wheel angle change in a left turn and right turn section in navigation as a rotation angle, and determining an angle between the straight ahead angle and the turning angle as a lane change angle; and turning off the direction indicator lamps on both sides when the handle angle is the straight angle, and flickering the direction indicator lamps on both sides until the handle angle recovers to the straight angle when the handle angle is the rotation angle, and An automatic blinking module for blinking the direction indicator lamps on both sides for a designated predetermined time or for a designated predetermined number of times at a lane change angle.

According to an embodiment of the present invention, direction indicators with high visibility can be provided in personal mobility, which is difficult to provide direction indicators due to a very narrow vehicle width compared to a vehicle.

In addition, when manipulating the steering wheel of personal mobility, the turn signal can be configured to automatically blink without a separate operation.
