Alternatively, the controller 301 may be disposed on a side of the plurality of light sources 203 opposite to the lamp housing 202. The controller 301 is electrically connected to the plurality of light sources 203.

In a first stage, the controller 301 may control the plurality of light sources 203 to be turned on or off in a first switching sequence for a first execution duration. For example, the first execution duration may be 0.67s, and the first switching sequence may be that the central light source 203 of the plurality of light sources 203 is turned on, and after the central light source 203 is turned off, the central light source 203 to the both end light sources 203 are turned off after the light sources 203 are turned on one by one.

In a second phase, the controller 301 may control the plurality of light sources 203 to be turned on or off in a second switching sequence for a second execution duration. For example, the second execution duration may be 0.67s, and the second switching sequence may be such that the two-end light sources 203 among the plurality of light sources 203 are turned on first, and after the two-end light sources 203 are turned off, the two-end light sources 203 are turned off until the center light source 203 is turned on one by one light source 203.

In a third stage, the controller 301 may control the plurality of light sources 203 to be turned on or off in a third switching sequence for a third execution duration. For example, the third execution duration may be 0.66s, and the third switching sequence may be that the central light source 203 is first lighted and then the light sources 203 are lighted one by one from the central light source 203 to the both end light sources 203.

In the above exemplary description, the controller 301 may control the light sources 203 to be turned on or off one light source 203, and the controller 301 may also control the light sources 203 to be turned on or off one light source 203 or more than two light sources 203. The first execution duration, the second execution duration, and the third execution duration are not specifically limited in the embodiments of the present application.

The control device of the embodiment of the application changes through the time sequence of the on or off of the plurality of light sources 203 in the position lamp 102, and then the position lamp generates various change states, such as rhythm change, rhythm change and the like, so that the inertia of human eyes can be avoided, the recognition degree of the motorcycle is improved, the state of the motorcycle is effectively displayed to drivers and surrounding people, and the user experience is improved.

Alternatively, the electrical signal may include a power-on signal generated when the motorcycle is powered on and a state electrical signal after the motorcycle is powered on.

The status electrical signal includes at least an electrical signal for indicating a fuel level of the fuel tank. The status electrical signal may also be other signals representing the state of the whole motorcycle, such as a signal representing the state of engine oil, a signal representing the tire pressure of the motorcycle, etc.

Alternatively, when the controller 301 acquires the status electrical signals, the controller 301 may be configured to change the statuses of the plurality of light sources 203 according to a pre-stored preset procedure corresponding to the power-on signal. The preset flow includes a switching sequence of each light source 203 of the plurality of light sources 203, an execution duration, and a preset light emission color.

Alternatively, the plurality of light sources 203 may also emit different colors. For example, the light source 203 may be an RGB LED.

Optionally, the different state electrical signals correspond to different preset light emitting colors.

For example, when the status electrical signal acquired by the controller 301 indicates that the oil level is below 25%, the preset light emission color of each light source 203 may be red. When the status electrical signal acquired by the controller 301 indicates that the oil level is between 25% and 50%, the preset light emission color of each light source 203 may be yellow. When the status electrical signal acquired by the controller 301 indicates that the oil level is between 50% and 75%, the preset light emission color of each light source 203 may be blue light. When the status electrical signal acquired by the controller 301 indicates that the oil level is between 75% and 100%, the preset light emission color of each light source 203 may be green light.

The control device of the embodiment of the application increases the attention of the motorcycle to drivers and surrounding crowds by emitting light with different colors, and further improves the recognition degree of the motorcycle. Moreover, through the state electric signal of the relevant state of monitoring the motorcycle, the state of the motorcycle can be represented through the color change of the position lamp, the effectiveness of the driver and the surrounding crowd on the state identification of the motorcycle is further improved, and the user experience is improved.

Fig. 3 is a schematic circuit diagram of a control device according to another embodiment of the present application. As shown in fig. 3, the circuit configuration of the control device includes: a controller 301, a first power supply module 302, and a plurality of light sources 203.

It will be appreciated that the controller 301 may be electrically connected to a power-up module of the motorcycle to obtain a power-up signal.

Alternatively, the controller 301 may be electrically connected to the power-on module through the first power supply module 302 to obtain the power-on signal.

Alternatively, the first power module 302 may independently supply power to the controller 301, such as the first power module 302 may be a regulated power supply. The power-up signal may be an analog signal or a digital signal. After the first power supply module 302 obtains the power-on signal, power is supplied to the controller 301.

Alternatively, the power-up module may power the controller 301. The first power supply module 302 may be a linear voltage regulator. The power-on signal may be an analog signal, and after the power-on signal output by the power-on module is stabilized by the first power supply module 302, a stable power supply voltage may be provided for the controller 301.

Alternatively, the controller 301 may obtain the status electrical signal through the transceiver module 303. The status electrical signals may be digital signals and the controller 301 may acquire the status electrical signals using a controller area network (Controller Area Network, CAN) protocol. The transceiver module 303 may be a CAN transceiver.

Referring to fig. 3, a plurality of light sources 203 may be arranged in groups, and each group may include one light source 203, two light sources 203, or a greater number of light sources 203. The plurality of light sources 203 are powered and driven by the second power supply module 306. The second power module 306 may be electrically connected to the power-on module to obtain a power-on signal.

It will be appreciated that the controller 301 may control the switching of the circuitry in which each light source 203 or group of light sources 203 is located.

Alternatively, the controller 301 is electrically connected to the plurality of light sources 203 through the constant current driving module 304.

The constant current driving module 304 may independently drive each group of the light sources 203 under the control of the controller 301.

Alternatively, the constant current driving module 304 may convert a constant voltage into a constant current output. By the arrangement mode, the driving current of each group of power supplies can be prevented from exceeding the maximum rated value, and the reliability is improved. And the light source 203 can be ensured to meet the expected brightness requirement, and the brightness and the chromaticity of the lamp beads of each light source 203 are kept consistent, so that the service life of the light source 203 is effectively prolonged.

It can be understood that in the case where the plurality of light sources 203 are RGB LEDs, the controller 301 may change the emission colors of the plurality of light sources 203 through the constant current driving module 304.

Alternatively, the second power supply module 306 may be electrically connected with the constant current driving module 304. The constant current driving module 304 is electrically connected to the controller 301 and the plurality of light sources 203, respectively.

Alternatively, the controller 301 may be electrically connected to the constant current driving module 304 through a serial interface. Illustratively, the controller 301 may employ an I2C (Inter-Integrated Circuit) serial communication protocol. Through the arrangement mode, fewer cables are needed for serial interface communication, a plurality of master servers and a plurality of slave servers are supported simultaneously, each frame can be confirmed to be transmitted through a response bit/no-response bit, and compared with a universal asynchronous receiver-Transmitter (Universal Asynchronous Receiver/Transmitter), the hardware structure is simple, and the reliability is high.

By way of example, the electronic components and cables shown in fig. 3 may be disposed entirely or partially on a flexible circuit board. The flexible circuit board may be adhered to the surface of the frame 204 in a paste manner.

Referring to fig. 2, the frame 204 may have a substantially axisymmetric shape. The frame 204 extends along both sides of the symmetry axis. The portions of the frame 204 extending from both sides are remote from the bottom end of the frame 204.

Alternatively, the frame 204 may be provided with a plurality of coupling members for detachably coupling the frame 204 with the housing 201.

Fig. 4 is a schematic view of the housing 201 of fig. 2 from another perspective. As shown in fig. 4, a side of the housing 201 facing the vehicle body 101 is provided with a plurality of connectors for attaching the housing 201 to the vehicle body 101.

Optionally, the housing 201 is provided with an interface 401. The interface 401 is located on the side of the housing 201 facing the vehicle body 101.

Illustratively, the interface 401 may be electrically connected to a circuit board of the motorcycle at one end and to a flexible circuit board at the other end.

Fig. 5 is a schematic structural diagram of a lampshade according to another embodiment of the present application. As shown in fig. 5, the lamp shade 202 of fig. 2 may include an inner lamp shade 501 and an outer lamp shade 502.

Alternatively, the inner globe 501 may be detachably coupled with the frame 204. The inner globe 501 may be fixed to the case 201 by the frame 204.

Alternatively, the outer envelope 502 may be sealingly connected to the housing 201. Illustratively, after the outer envelope 502 is detachably connected to the housing 201, the outer envelope 502 may be sealed to the housing 201 by gluing.

Fig. 6 is a schematic view of the inner globe 501 of fig. 5 from another perspective. As shown in fig. 6, the inner globe includes a first light guide 601 and a second light guide 602. The first light guide 601 covers the plurality of light sources 203 on the frame 204. The second light guide 602 and the first light guide 601 are adjacent to each other. The second light guide 602 is disposed at an edge of the first light guide 601.

For example, referring to fig. 6, the first light guide 601 may be a bar shape substantially in a curved state surrounding the plurality of light sources 203. The second light guide 602 may be in the shape of a closed loop surrounding the area where the head lamp 103 is located.

Alternatively, the first light guide 601 may be a light-equalizing plate for making the light emitted from the plurality of light sources 203 uniform. Illustratively, the first light guide 601 may be milky white.

Alternatively, the second light guide 602 may be a light shielding plate for preventing the plurality of light sources 203 from being strung with the head lamp 103. The second light guide 602 may be black, for example.

Alternatively, the first light guide 601 may be protruded with respect to the surface of the inner globe 501. A space exists between the first light guide 601 and the surface of the frame 204, and a space exists between one side of the first light guide 601 opposite to the plurality of light sources 203 and the plurality of light sources 203.

Alternatively, the vertical distance between the surface of the first light guide 601 opposite to the side of the plurality of light sources 203 and the plurality of light sources 203 is in the range of 20 to 40 mm. By this arrangement, the light source 203 can be used as little as possible while satisfying the emission intensity requirement of the motorcycle position lamp.

It can be understood that if the distance between the plurality of light sources 203 and the surface of the first light guide body 601 is too large, there is a problem of low optical efficiency, and the light source 203 with higher power is required to meet the light intensity required by the position light, see fig. 7, where the distance between the light sources is too large, and fig. 7 is a schematic diagram of the light emitting effect of different vertical distances between the surface of the first light guide body 601 and the plurality of light sources 203 provided in the embodiment of the present application.

Referring to fig. 7, if the distance between the plurality of light sources 203 and the first light guide 601 is too small, such as in the first case where the intermediate distance is too small in fig. 7, a dark area 701 exists between the light emitting ranges of the plurality of light sources 203, resulting in uneven light emission of the plurality of light sources 203.

Referring again to fig. 7, in the second case where the pitch is too small, the light emitting range coverage of each light source 203 is too small, and a larger number of light sources 203 are required to satisfy uniformity.

In the range of 20-40 mm vertical spacing between the surface of the first light guide body 601 and the plurality of light sources 203, which corresponds to the situation of moderate spacing in fig. 7, the problems of low optical efficiency caused by overlarge spacing, uneven light emission caused by overlarge spacing and a plurality of required light sources 203 can be overcome.

Fig. 8 is a flowchart of a control method of a motorcycle position lamp according to another embodiment of the present application. The control method shown in fig. 8 can be applied to the control apparatus shown in fig. 2 to 6. The control method comprises the following steps:

Optionally, the electric signal includes a power-on signal generated when the motorcycle is powered on and a state electric signal after the motorcycle is powered on, and the state electric signal includes at least an electric signal for indicating the fuel amount of the fuel tank.

when the status electrical signals are acquired, the status of the plurality of light sources 203 is changed according to a pre-stored preset flow corresponding to the power-on signals.

Optionally, the preset flow includes a switching sequence, an execution duration, and a preset light emission color of each light source 203 of the plurality of light sources 203.

Alternatively, the preset emission color of each light source 203 in the preset flow may be determined according to the status electrical signal.

Optionally, when acquiring the status electrical signals, changing the status of the plurality of light sources 203 according to a pre-stored preset procedure corresponding to the power-on signal includes:

acquiring a preset luminous color of each light source 203 corresponding to the state electric signal in a preset process;

controlling the plurality of light sources 203 to emit a preset light emission color or to be turned off in a first switching sequence for a first execution duration;

the plurality of light sources 203 are controlled to emit a preset light emission color or to be turned off in a third switching sequence for a third execution duration.

For example, when the acquired status electrical signal indicates that the oil level is below 25%, the preset light emission color of each light source 203 may be red. When the acquired state electric signal indicates that the oil level is between 25% and 50%, the preset light emission color of each light source 203 may be yellow. When the acquired status electrical signal indicates that the oil level is between 50% and 75%, the preset light emission color of each light source 203 may be blue light. When the acquired status electrical signal indicates that the oil level is between 75% and 100%, the preset light emission color of each light source 203 may be green light.
