For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0046] Such as Figure 1As shown in the figure, the method for controlling a bicycle taillight provided by an embodiment of the present invention includes the following steps: obtaining an acceleration signal; combining the acceleration signal and map data to determine the vehicle driving state; and controlling the bicycle taillight according to the vehicle driving state.
[0047] According to the acceleration signal, it can be determined that the cycling state is an acceleration stage or a deceleration stage. Combining information such as uphill, downhill, turning, and turning angle in the map data, on the one hand, it can verify whether the current acceleration or deceleration meets the safe cycling requirements at the current location. Obviously, if the acceleration signal is decelerating in a sharp turn area, it proves that cycling is relatively safe and also proves that the acceleration signal is normal. On the other hand, by combining the acceleration signal and map data, the upcoming cycling behavior can be predicted. When in the acceleration stage and in a downhill area, it can be predicted that braking will be performed, and the braking warning light can be controlled to light up when the acceleration or speed reaches a preset value.
[0048] In an embodiment of the present invention, the method for controlling a bicycle taillight further includes: obtaining the user's cycling route; predicting turning and / or braking according to the vehicle's location, and correspondingly controlling the bicycle taillight.
[0049] According to the preset cycling route, the turn signal in the bicycle taillight can be automatically controlled to light up at a turn, or the warning light in the bicycle taillight can be automatically controlled to continuously light up or flash when entering a bumpy section or a continuous curve. Of course, the method for controlling a bicycle taillight can only control the turn signal or the brake light, etc.
[0050] In an alternative embodiment, the method for controlling a bicycle taillight further includes: obtaining a power signal; if the power is lower than a preset value, the number of light-emitting LEDs in the bicycle taillight is reduced, or the brightness of the bicycle taillight is reduced. Additionally, the number of light-emitting LEDs can also be reduced and the taillight brightness can be decreased when the power is low. This is beneficial to extend the lighting duration of the bicycle taillight in a low-power state, thereby maintaining the basic safety warning function and ensuring safety during cycling as much as possible.
[0051] The method for controlling a bicycle taillight further includes: comparing the vehicle's location with dangerous sections in the map data, and when driving to a dangerous section, controlling the warning light of the bicycle taillight to light up.
[0052] According to the map data, a section where the ramp angle reaches a preset angle, or the ramp length reaches a preset length, or the turning angle exceeds a set angle can be defined as a dangerous section. At this time, the warning light is controlled to light up to warn the following vehicles to prevent rear-end collisions.
[0053] Such as Figure 2As shown in the figure, the bicycle taillight provided by the embodiment of the present invention includes: a lamp group module 100, a battery module 200, a Faraday supercapacitor 300, and a control module 400; the battery module 200, the Faraday supercapacitor 300, and the control module 400 are respectively connected to the lamp group module 100; the battery module 200 and the Faraday supercapacitor 300 are respectively connected to the control module 400.
[0054] Among them, the control module 400 is used to execute a control program to implement the bicycle taillight control method described in the above embodiment. In addition to having the technical advantages of the above bicycle taillight control method, the bicycle taillight described in this embodiment can use the Faraday supercapacitor 300 for fast charging and energy storage, and is particularly suitable for use cases where the charging time is short and the most basic warning function of the bicycle taillight needs to be ensured to ensure night riding safety.
[0055] In the embodiment of the present invention, the lamp group module 100 includes: a left turn signal, a right turn signal, and a warning light, and the warning light is installed between the left turn signal and the right turn signal.
[0056] Among them, the warning light may include multiple LED lights. In the case of low battery power, only three of the LED lights can be retained and lit at a lower brightness.
[0057] See Figure 4 and Figure 5 , the bicycle taillight is configured with a streamlined housing 600, and the streamlined housing 600 has a buckle structure adapted to the seat.
[0058] Generally, the bicycle taillight is installed at the lower position behind the seat. The use of a buckle structure facilitates disassembly and assembly operations. In addition, the bicycle taillight is configured with a streamlined housing 600 to reduce wind resistance during forward movement.
[0059] In an alternative embodiment, the streamlined housing 600 is configured with a lift surface. In the forward state, the airflow passes through the lift surface and provides lift for the bicycle taillight. Through this lift, the pressure of the wheel on the ground can be reduced, and thus the friction between the bicycle and the ground can be reduced, making the riding more convenient.
[0060] Among them, the lift surface extends along a waveform curve in a plane perpendicular to the forward direction. The waveform curve includes: a first flat section, a first downward wave section, a first upward wave section, a second downward wave section, a second upward wave section, a third downward wave section, a third upward wave section, a fourth downward wave section, and a second flat section;
[0061] The ordinate of the first flat section and the second flat section , the abscissa of the first flat section is 0 - 2.2, and the abscissa of the second flat section is 56.62 - 58.82;
[0062] The ordinate of the first downward wave section , the abscissa of the first downward waveband is 2.2 to 9.0;
[0063] The ordinate of the first upward waveband , the abscissa of the first upward waveband is 9.0 to 19.41;
[0064] The ordinate of the second downward waveband , the abscissa of the second downward waveband is 19.41 to 23.41;
[0065] The ordinate of the second upward waveband , the abscissa of the second upward waveband is 23.41 to 35.41;
[0066] The ordinate of the third downward waveband , the abscissa of the third downward waveband is 35.41 to 39.41;
[0067] The ordinate of the third upward waveband , the abscissa of the third upward waveband is 39.41 to 49.82;
[0068] The ordinate of the fourth downward waveband , the abscissa of the fourth downward waveband is 49.82 to 56.62.
[0069] A comparative test was carried out under the condition of 40 km / h, and the test results are shown in the following table:
[0070]
[0071] In addition, when the streamlined housing 600 is installed under the rear side of the seat from bottom to top by a snap structure, the lift force generated by the streamlined housing 600 during forward movement can ensure that the streamlined housing 600 is firmly clamped relative to the seat, reducing the risk of the riding tail light loosening and falling off.
[0072] In an alternative embodiment, refer to Figure 3 、 Figure 4 and Figure 5 , the Faraday supercapacitor 300 is snap-connected to the streamlined housing 600. Among them, the streamlined housing 600 includes a streamlined bracket and a bionic housing that is snap-connected to the streamlined bracket. The pins of the Faraday supercapacitor 300 are welded to the circuit board 500, and the Faraday supercapacitor 300 is snapped onto the streamlined bracket. The circuit board 500 is bolted to the streamlined bracket, and then the bionic housing is snap-connected to the streamlined bracket, thereby enclosing the electronic components inside the streamlined housing 600, ensuring the stable installation of the electronic components and facilitating the improvement of circuit stability.
[0073] Furthermore, the riding tail light further includes a communication module for information interaction with a mobile terminal or a server.
[0074] Among them, the mobile terminal can correspondingly develop a program software for pairing and connecting with the bicycle taillight. The user can set the cycling route, adjust the working state of the bicycle taillight, etc. through this program software. In addition, the actual cycling route can be recorded and formed in combination with the positioning information of the mobile terminal. When the number of users increases and the server collects more cycling routes, the automatic control of the bicycle taillight in combination with the cycling route will be more accurate.
[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
