Detailed ways

In order to illustrate the central idea of the utility model in the column of the above-mentioned new content, it is expressed in specific embodiments. Various objects in the embodiments are drawn in proportions suitable for illustration rather than actual components, and are described first.

As shown in Figures 1 to 3, the utility model is a bicycle light with the function of automatically adjusting the lighting distance by hand, which mainly includes:

A car light set 10, which includes at least one light-emitting component 11 and a reflector lampshade 12, used to generate an illumination beam; for example: the car light set 10 includes at least two light-emitting components 11 with different distances from the reflector lampshade 12, 11', so as to generate light beams with different lighting distances by means of different light emitting components 11, 11'.

A lighting mode controller 20, which is electrically coupled to the car light group 10, so as to control the car light group 10 to generate lighting beams with different far and near lighting distances.

At least one switching switch 30, the switching switch 30 is electrically coupled to the lighting mode controller 20 to switch the car light group 10 into manual low light lighting mode, manual high light lighting mode and adaptive lighting mode. And the switch 30 can be a single cycle switch or a switch group made up of a plurality of keys. as well as

A car light shell 40, which is a hollow shell, so as to accommodate the above-mentioned components, and one end of the car light shell 40 is an open end 41, which can be used to accommodate the car light group 10, and the switch 30 is 40 places are exposed on the lamp housing.

Furthermore, the lighting mode controller 20 includes a logic circuit module 21, which can switch and adjust the lighting distance of the car light group 10 in the adaptive lighting mode. Wherein, the logic circuit module 21 is connected to a sensing component 50 . The sensing component 50 may include at least one of a photometric sensor 51, a passing sensor 52 or a speed sensor 53. For example, the photometric sensor 51 is a Cds photoresistor located at the top of the car lamp housing 40. When the luminosity is stronger, that is, during the day, the photoresistor voltage divider is smaller so that the output is a low voltage; when the luminosity is weaker, that is, at night, The larger the photoresistor voltage divider, the higher the output voltage. According to this characteristic, the state of the ambient luminosity is judged, so that an ambient luminosity sensing signal can be provided to the logic circuit module 21 .

And this car meeting sensor 52 is a Cds photoresistor that is located at the near open end 41 of the car lamp housing 40. When the luminosity sensed by it is stronger, that is, when meeting a car with the opposite car, the photoresistor voltage divider is smaller so that its The output is a low voltage; when the luminosity is weaker, that is, when there is no oncoming car meeting the opposite direction, the greater the voltage division of the photoresistor makes its output a high voltage. This is used to judge the state of meeting vehicles and normal riding (no meeting vehicles), so that the lighting sensing signal for oncoming vehicles can be provided to the logic circuit module 21 .

And as shown in Figure 4, the speed sensor 53 is a speed stopwatch that can be assembled at the bicycle body, so that the vehicle body speed sensing signal can be provided to the logic circuit module 21. Wherein, the lighting mode controller 20 includes a wireless communication module 22 for wireless transmission with the sensing component 50. For example, the speed sensor 53 can be a speed stopwatch set separately, and the vehicle body speed sensing signal can be transmitted to the logic circuit module 21 through the wireless communication module 22 through wireless transmission.

After understanding the detailed structure of the above-mentioned utility model, the following details the action principle of the utility model one by one:

As shown in Figure 5 and Figure 6, the rider can switch the lighting mode controller 20 to the manual low light lighting mode, manual far light lighting mode and adaptive lighting mode through the switch 30, so that the car light group 10 Produces lighting beams with different far and near lighting distances.

For example, in the manual low-beam lighting mode, the low-beam light-emitting component 11 is driven and the high-beam light-emitting component 11' is turned off, so that the light beam is refracted or reflected by the reflector lampshade 12 to generate a close-range lighting beam. On the contrary, when driving the high-beam light-emitting component 11' and closing the low-beam light-emitting component 11', the light beam is refracted or reflected by the reflector lampshade 12 to generate a long-distance lighting beam.

And when the lighting mode controller 20 is in the adaptive lighting mode, the logic circuit module 21 can accept the sensing signal from the sensing component 50, and automatically judge and control the lighting distance of the car light group 10 by means of the logic circuit module 21 , avoiding the trouble of manually switching the far and near lights and the problems of human judgment or operation error.

For example, when the light sensor 51 senses that the ambient light is stronger than the set value, it means that the ambient light is sufficient for the rider to identify the road ahead, and the lighting can be automatically turned off or only the low beam is turned on as a daytime running light for identification.

And the passing vehicle sensor 52 is due to being arranged at the place facing the oncoming vehicle, the passing vehicle sensor 52 can detect the lighting of the opposite passing vehicle, when the passing vehicle sensor 52 senses that the object has an approaching vehicle, it can automatically switch the high beam to the low beam lights to avoid visual stimulation to oncoming vehicles caused by lighting beams. And this switching action can include a delay time, after the vehicle meeting sensor 52 detects that the oncoming vehicle passes by, the low beam light state is maintained for a period of time, so as to avoid the light emitting components 11, 11' from switching the state of the far and near light too frequently when the opposite vehicle is coming continuously. damage or other problems.

And this speed sensor 53 detects the running speed of bicycle body, under the low-speed driving state, can switch to dipped beam lighting automatically. When the driving speed exceeds a predetermined value, it will automatically switch to high beam lighting to increase the rider's field of vision so that the rider has more reaction time to cope with unexpected road conditions. Furthermore, when the speed sensor 53 detects that the driving speed of the bicycle body increases, in addition to switching the far and low beam lighting, the current amount can also be increased as the speed of the driving increases, so as to achieve the purpose of adjusting the brightness of the lighting with the speed of the driving. Driving safety.

The logic circuit module 21 can not only accept the sensing signals of the above three sensing devices for judgment, but also can judge by combining two or more sensing signals of the photometric sensor 51, the passing sensor 52 or the speed sensor 53. For example, the light sensor 51 senses that the ambient light level is lower than the set value, the passing sensor 52 senses that there is no oncoming vehicle in the opposite direction, and the speed sensor 53 detects that the speed is higher than the set value before turning on the high beam. Or when the light sensor 51 senses that the ambient light is lower than the set value, the speed sensor 53 senses that the speed is higher than the set value, and the passing sensor 52 senses that there is an oncoming vehicle in the opposite direction, it will automatically switch the high beam to Low beam lights. Make logical judgments with the help of multiple conditions to avoid the inaccurate judgment of a single condition.

Furthermore, as shown in Figure 7 and Figure 8, it is another embodiment of the present utility model, wherein, the lamp group 60 includes:

a light emitting component 61 capable of emitting at least one light beam;

A reflector lampshade 62, which can be moved closer to or away from the light-emitting component 61 and is movably arranged in the car light housing 40. The reflector lampshade 62 can reflect the light beam of the light-emitting component 61 and project the bicycle light; and

An illumination distance adjustment device 63, which can change the relative distance between the light-emitting component 61 and the reflector lampshade 62, so that the car lamp group 60 forms beams of different illumination distances. For example, the lighting distance adjustment device 63 is composed of a screw rod 631 and a power source 632. One end of the screw rod 631 is screwed to the reflector lampshade 62, the other end is connected to the power source 632, and the screw rod 631 passes through a The perforated seat 633 in the lamp housing 40. When the power source 632 drives the screw 631 to rotate, the reflector lampshade 62 can be displaced.

In this way, the lighting mode controller 20 only needs to be electrically coupled with the power source 632 of the lighting distance adjustment device 63 to control the displacement of the reflector lampshade 62 on the emission path of the light beam, and change the position where the light beam is projected on the reflector lampshade 62, so that To achieve the purpose of adjusting the focal length of the 60 beams of the car light group and producing different lighting distances.

The vehicle light group of the utility model has multiple lighting modes such as far and near lights, and can be convenient for the rider to manually switch the far and near lights. The lighting mode controller also has an adaptive lighting mode capable of logic operation by itself, which can automatically judge and switch the far and near lighting of the bicycle light according to the sensing signal of the sensing component. Avoid the problem that the rider cannot switch by himself during the riding process.

The above-mentioned embodiments are only used to illustrate the utility model, and are not intended to limit the scope of the utility model. All modifications or changes that do not violate the spirit of the utility model belong to the patent scope of the utility model.
