Directional warning light device for bicycle

The present invention relates to a directional warning light device for a bicycle, and more particularly to a directional warning light device for projecting a warning signal toward a ground with the steering of a bicycle.

Bicycles are one of the most popular means of transportation in recent years and are also very popular sports tools. As more and more people are engaged in cycling, the safety of the bicycle is gradually being taken seriously. In the early days, the bicycle was not mandated to be equipped with night lighting and night warning equipment, but with the person riding the bicycle. As the number of bicycles increases, the visibility of the bicycle increases on the road, especially in the case of poor sight or nighttime cycling. The bicycle is often not equipped with the nighttime illumination or the nighttime warning device, causing frequent traffic accidents caused by the bicycle. Especially when the bicycle is turning, it is not equipped with a directional light like a car or a locomotive, so it is easy to have a traffic accident during the steering.

For this purpose, a bicycle smart seat cushion system includes a bicycle, an intelligent control system, a display control system, and an auxiliary device, and the intelligent control system further includes a pad control, as disclosed in the Chinese Patent Publication No. M496594 and the M496595 patent. a device, a sensing device, a lens device, a lighting device, a warning device, and a power supply device, and the lighting device further includes an auxiliary lighting device disposed at a front end of a pad of the bicycle and a plurality of the bicycles disposed on the bicycle A rear light, a two-directional indicator light and a decorative light at the rear end of the seat cushion are used to achieve the steering warning effect on the rear of the bicycle by using the two direction indicators behind the seat cushion.

As shown in FIG. 5, the method for controlling the warning state of the direction warning light device 10 is further disclosed. Please refer to FIG. 4, FIG. 6 and FIG. 7 as follows. First, the steps are as follows: First, step S101 is performed, and the switch is first pressed. 281, the warning light device 10 is turned on and enters the warning state; then, in step S102, the direction warning light device 10 first obtains a connection with the communication device through the wireless communication module 63; then, step S103 is performed, The GPS positioning system determines whether the bicycle 80 is moving; if yes, proceeding to step S014, starting the braking light group 50, causing the braking light group 50 to start blinking to alert the vehicle behind the bicycle 80; or, returning In step S103, it is re-determined whether the bicycle 80 is moving. During the movement of the bicycle 80, step S105 is performed to determine whether the bicycle 80 is braking through the position change of the GPS positioning system on the communication device; if the vehicle is in the braking state, proceed to step S106 to determine whether it is an emergency braking; In the emergency braking state, step S107 is performed, the braking light group 50 blinks at a frequency of ten times per second to warn the vehicle behind the bicycle 80; if it is in a non-emergency braking state, step S108 is performed, the braking vehicle is performed. The light unit 50 flashes at a frequency of four times per second to alert the vehicle behind the bicycle 80. If it is determined in the above step S105 that the vehicle is in the non-driving state, step S109 is performed to determine whether the bicycle 80 is steered, and if it is determined to be steered, it is determined whether it is a left turn or a right turn, and if it is a left turn, the steps are performed. S110, the left turn projection lamp set 30 is activated; if it is right turn steering, step S111 is performed to activate the right turn projection lamp set 40; if the determination is no in step S109, step S112 is performed to determine whether to press the switch. If the signal for pressing the switch 281 is received, the process proceeds to step S113, and the direction of the warning light device 10 is turned off and then entered. On the other hand, after steps S107, S108, S109, S110, and S111, the process returns to step S103 to re-determine whether or not the bicycle 80 is moving.

As shown in FIG. 3 and FIG. 6, when the bicycle 80 performs a left turn steering, the attitude sensor 61 generates the left turn steering signal and transmits it to the control unit 62, at which time the control unit 62 receives the left turn steering. After the signal is turned on, the left turn projection lamp set 30 is activated to cause the first light emitting component 31 to emit the first light and pass through the left refractive projection cover 323 of the first projection module 32. Projected outside to project the left turn indicator 261 onto a ground to form a left turn direction warning signal 81, thereby alerting the rear vehicle that the bicycle 80 is making a left turn.

As shown in FIG. 3 and FIG. 7, when the bicycle 80 performs a right turn steering, the attitude sensor 61 generates the right turn steering signal and transmits it to the control unit 62, at which time the control unit 62 receives the right turn. After the turn signal, the right turn projection lamp set 40 is activated to cause the second light emitting component 41 to emit the second light and pass through the right refractive projection cover 423 of the second projection module 42. Projecting outwardly to project the right turn indicator 271 onto the ground to form a right turn direction warning signal 82, thereby alerting the rear vehicle that the bicycle 80 is making a left turn.

In addition, the left turn direction warning signal 81 and the right turn direction warning signal 82 may change with different brightness levels according to the tilt angle of the bicycle 80, and the brightness change is changed according to the angle of the body tilt when the bicycle 80 is turned. When the tilt angle of the vehicle body is larger, the brightness of the left turn direction warning signal 81 and the right turn direction warning signal 82 are higher. On the contrary, the lower the tilt angle of the vehicle body, the lower the brightness of the left turn direction warning signal 81 and the right turn direction warning signal 82. The brake warning signal will change with different brightness as the speed is slowed. The change of the brightness is determined by the speed of the bicycle 80, and the speed is determined mainly by the position change of the GPS positioning system of the communication device. Determining the speed change of the bicycle 80, and then using the speed change to control the blinking speed of the brake light group 50, for example, when the speed change suddenly becomes large, the blinking speed of the brake light unit 50 is ten times per second, and when When the speed is maintained, the blinking speed of the brake light unit 50 is four times per second, thereby using different blinking speeds to alert the rear vehicle of the traveling state of the bicycle 80.

Compared with the prior art, the present invention directly projects the steering onto the ground through the left-turning projection light group 30 and the right-turning projection light group 40, and can achieve an eye-catching reminding effect at night. The left turn direction warning signal 81 and the right turn direction warning signal 82 will change with different brightness according to the tilt angle of the bicycle 80, so as to enhance the recognition effect of the rear vehicle through the brightness changes, thereby improving the bicycle 80. Safety in night riding.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any skill and refinement made by those skilled in the art without departing from the spirit and scope of the present invention should be covered.
