Description

According to the present invention, when the brake is operated, the power generation unit and the light emitting unit (high brightness LED) connected to the power generation unit are lit and lit regardless of the failure of the electric system such as the battery, and the brake can be urged to the following vehicle. It relates to the lamp unit.

Even if the brake is activated and the vehicle is stopped or suddenly stopped while driving, the light bulb may be burned out or the brake lamp may not turn on due to a failure in the electrical system such as the battery. is there.
Furthermore, in recent years, equipped with a radar brake support system, if the brake light of the front car stops without being visually observed due to the above circumstances, the following car is very uneasy and dangerous.
Also, as a precaution against accidents, the safety measures are more serious as the three-story stop plate, etc., is obligated to prevent secondary accidents.
In order to solve such problems, there are many brake lamp systems, but a brake lamp system disclosed in Patent Document 1 below is known. In the brake lamp system, when the brake pedal is depressed, the connected battery and brake lamp are turned on and turned on by the operation of the control device, but it is determined whether the driver himself is on or not. It is difficult to confirm.
Further, when the brake lamp is not turned on, it is impossible to immediately confirm whether the cause is any of the battery, the brake lamp, and the control device.
The present invention is a brake lamp unit that can be lit and lit by an independent unit, with the power generation unit and the light emitting unit attached to the positions of the left and right brake systems.

JP2015-67253A

As described above, when the brake lamp system is depressed, the connected battery and brake lamp are turned on and turned on by the operation of the controller, but is the driver lighting the brake lamp? It's difficult to check while driving.
Further, when the brake lamp is not turned on, there arises a problem that any of the battery, the brake lamp, and the control device cannot be immediately confirmed.
The present invention has been made in view of the above circumstances, and its purpose is that when a brake is operated, a power generation unit and a light emitting unit connected to the power generation unit (high power) regardless of whether the brake lamp is out or a battery or other electrical system is malfunctioning. The present invention is to provide a brake lamp unit that emits and lights up a luminance LED) and can prompt a warning to the following vehicle.

Even if the brake lamp or battery according to the present invention for achieving the above object is exhausted, it is possible to notify the following vehicle of a stop or a sudden stop. In addition, in the brake lamp unit that can prevent accidents, the brake lamp unit is composed of a power generation unit and a light emitting unit that is located on the left and right of the existing high-brightness LED, and lights up when the brake is operated. The car can be alerted.
The power generation unit is installed at a position incidental to the brake pad near the rear tire. Furthermore, the generator uses a magnet generator that has a small number of failures and has a useful life, and equally attaches the magnets in a ring shape. There is a brightness of 15 lux at a low traveling speed of 15 km / h, and a brightness of 50 lux at a normal traveling speed of 50 km / h. The brake lamp lighting can be confirmed, power can be generated during the brake operation time, and a warning can be promptly issued to the following vehicle.

1) When the brake is activated during driving, the power generation unit and the light-emitting unit (high-intensity LED) connected to it are located at the existing left and right brake lamp positions, regardless of the failure of the electrical system such as the battery. A warning can be urged to the following vehicle.
2) The operation time (high-luminance LED emission time) is until the vehicle stops when the brake is depressed, and the light can be turned on.
(As an option, a battery can be attached and charged, and while the brake is depressed, the high-brightness LED can be lit and lit as an operating time.)
3) Since the power generation unit and the light emitting unit are independent, the connection is simple and the installation is easier, so that failure can be reduced.

Brake lamp capable of illuminating and lighting a power generation unit and a light emitting unit connected to the power generation unit (high luminance LED) regardless of a failure of an electric system such as a battery when the brake according to the present invention is operated A preferred embodiment of the unit will be described with reference to the drawings.
FIG. 1 is a perspective view showing an outline of a general automobile brake system.

This general automobile brake system B has a master cylinder 4 as an axis, a disc brake 2 at the front wheel, a drum brake 1 at the rear wheel, a parking brake lever P near the seat, and a brake pedal at the foot. It consists of appending three.

FIG. 2 is a mechanism diagram showing a brake system for front wheels and rear wheels in a general automobile.
This brake system is integrated with a brake booster 4 attached to a brake pedal 3, a brake oil tank 5, a master cylinder 6, a piston 8, etc., and a brake pad 10 mainly composed of a brake disc 9 on a front wheel, a caliber 11, a piston 12, etc. The rear wheel includes a brake plate 13 mainly including a brake drum 7, an adjuster 14, a return spring 15, a brake lining 16, and the like connected to a brake pipe 18 and a brake hose 19.
