[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Physical quantities in formulas, if not separately marked, should be understood as basic quantities of the base units of the International System of Units, or derived quantities derived from the basic quantities through mathematical operations such as multiplication, division, differentiation or integration.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 As shown, the riding taillight control method provided by the embodiment of the present invention includes the following steps: obtaining an acceleration signal; judging the driving state of the vehicle by combining the acceleration signal and map data; and controlling the riding taillight according to the driving state of the vehicle.

[0023] According to the acceleration signal, it can be determined whether the riding state is in the acceleration stage or the deceleration stage. Combined with the information such as uphill, downhill, turning and turning angle in the map data, on the one hand, it can be verified whether the current acceleration or deceleration meets the safe riding requirements at the location. Obviously, if the acceleration signal is decelerating in the sharp turning area, it proves that the riding is relatively safe and that there is no abnormality in the acceleration signal. On the other hand, combined with the acceleration signal and map data, the upcoming riding behavior can be predicted. In the acceleration stage and in the downhill area, it can be predicted that braking will be performed, and the brake warning light can be controlled to light up when the acceleration or speed reaches the preset value.

[0024] In an embodiment of the present invention, the riding taillight control method further includes: obtaining a user's riding route; predicting steering and / or braking according to the position of the vehicle, and controlling the riding taillight accordingly.

[0025] According to the preset riding route, the turn signal in the riding taillight can be automatically controlled to light up at the turn, and the warning light in the riding taillight can be automatically controlled to light up or flash continuously when entering a bumpy road section or continuous curves. Of course, the riding taillight control method can only control the turn signal or brake light.

[0026] In an optional embodiment, the riding taillight control method further includes: obtaining a power signal; if the power is lower than a preset value, reducing the number of light-emitting LEDs in the riding taillight, or reducing the brightness of the riding taillight. In addition, the number of light-emitting LEDs can be reduced and the brightness of the taillight can be reduced when the power is low. This is conducive to extending the lighting time of the riding taillight in a low-power state, thereby maintaining the basic safety warning function and ensuring safety during riding as much as possible.

[0027] The riding taillight control method further includes: comparing the dangerous road section in the map data according to the position of the vehicle, and when the vehicle reaches the dangerous road section, controlling the warning light of the riding taillight to light up.

[0028] 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 the set angle can be defined as a dangerous section. At this time, the warning light is controlled to light up to warn the rear vehicle to prevent rear-end collision.

[0029] like Figure 2 As shown, the riding taillight provided by the embodiment of the present invention includes: a light group module 100, a battery module 200, a Faraday super capacitor 300 and a control module 400; the battery module 200, the Faraday super capacitor 300 and the control module 400 are respectively connected to the light group module 100; the battery module 200 and the Faraday super capacitor 300 are respectively connected to the control module 400.

[0030] Among them, the control module 400 is used to execute the control program to implement the riding taillight control method recorded in the above-mentioned embodiment. In addition to having the technical advantages of the above-mentioned riding taillight control method, the riding taillight recorded in this embodiment can use the Faraday supercapacitor 300 to quickly charge and store energy, which is particularly suitable for the situation where the charging time is short and the most basic riding taillight warning function needs to be guaranteed to ensure the safety of night riding.

[0031] In the embodiment of the present invention, the lamp assembly module 100 includes: a left turn signal lamp, a right turn signal lamp and a warning light, and the warning light is installed between the left turn signal lamp and the right turn signal lamp.

[0032] The warning light may include multiple LED lights. In the case of low battery, only three of the LED lights may be left lit at a lower brightness.

[0033] See also Figure 4 and Figure 5 The riding taillight is provided with a streamlined housing 600, and the streamlined housing 600 has a buckle structure adapted to the seat.

[0034] Generally, the riding taillight is installed at the lower rear side of the seat, and adopts a buckle structure for easy disassembly and assembly. In addition, the riding taillight is provided with a streamlined housing 600 to reduce wind resistance during the forward movement.

[0035] In an optional embodiment, the streamlined shell 600 is provided with a lift curved surface. When the bicycle is moving forward, air flows through the lift curved surface and provides lift for the riding taillight. The lift can reduce the pressure of the wheel on the ground, thereby reducing the friction between the bicycle and the ground, making riding easier.

[0036] The lift surface extends along a wave curve on a plane perpendicular to the forward direction, and the wave curve includes: a first flat section, a first downward wave band, a first upward wave band, a second downward wave band, a second upward wave band, a third downward wave band, a third upward wave band, a fourth downward wave band and a second flat section; The vertical coordinates of the first and second flat segments , the horizontal coordinate of the first flat section is 0~2.2, and the horizontal coordinate of the second flat section is 56.62~58.82; The vertical coordinate of the first downward band , the horizontal coordinate of the first downward band is 2.2~9.0; The vertical coordinate of the first upward band , the horizontal coordinate of the first downward band is 9.0~19.41; The vertical coordinate of the second downward band , the horizontal coordinate of the second downward band is 19.41~23.41; The vertical coordinate of the second upward band , the horizontal coordinate of the second upward band is 23.41~35.41; The vertical coordinate of the third downward band , the abscissa of the third downward band is 35.41~39.41; The vertical coordinate of the third upward band , the abscissa of the third upward band is 39.41~49.82; The vertical coordinate of the fourth downward band , the horizontal coordinate of the fourth downward band is 49.82~56.62.

[0037] A comparative test was conducted at 40km / h, and the test results are as follows:

[0038] In addition, when the streamlined shell 600 is installed from bottom to top at the lower rear side of the seat using the snap-fit ​​structure, the lift generated by the streamlined shell 600 when moving forward can ensure that the streamlined shell 600 is firmly snapped relative to the seat, reducing the risk of the riding taillight loosening and falling off.

[0039] In an alternative embodiment, see Figure 3 , Figure 4 and Figure 5 , the Faraday supercapacitor 300 is snap-connected with the streamlined housing 600. The streamlined housing 600 includes a streamlined bracket and a bionic housing snap-connected with the streamlined bracket, the pins of the Faraday supercapacitor 300 are welded to the circuit board 500, and the Faraday supercapacitor 300 is snap-connected to the streamlined bracket, the circuit board 500 is bolted to the streamlined streamlined bracket, and then the bionic housing is snap-connected with the streamlined bracket, so that the electronic device is enclosed inside the streamlined housing 600, ensuring that the electronic components are firmly installed, which is conducive to improving the circuit stability.

[0040] Furthermore, the riding taillight also includes a communication module, and the communication module is used for exchanging information with a mobile terminal or a server.

[0041] Among them, the mobile terminal can develop corresponding program software that is paired with the cycling taillight. Users can use the program software to set the cycling route, adjust the working status of the cycling taillight, etc. In addition, the positioning information of the mobile terminal can be combined to record and form the actual cycling route. When the number of users increases and the number of cycling routes collected by the server increases accordingly, the automatic control of the cycling taillight combined with the cycling route will be more accurate.

[0042] 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 it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
