[0048] In this embodiment, the detection unit 14 can include a plurality of distance sensors, such as ultrasonic sensors, infrared sensors, or laser radars, etc. These sensors are respectively arranged at the front, rear, and both sides of the vehicle body, and are configured to detect obstacles around the vehicle body in all directions and measure the distance between the vehicle body and the obstacles. The detection unit 14 converts the detected distance information into a detection signal and transmits the detection signal to the control unit 12.

The projection unit 13 can dynamically switch the projection mode according to the different working modes of the vehicle body at present, realize dynamic adjustment of the warning mode, and under the premise of realizing projection warning, compared with the existing two-wheeled vehicle light warning mode, the visibility can be improved in the night or low light environment, the recognition efficiency of the rear vehicle is significantly enhanced, the collision risk is reduced, and the safety of the two-wheeled vehicle in the complex traffic environment is improved.

[0052] Further, the projection unit 13 can include a first projection module 133.

[0053] The first projection module 133 is arranged at the tail of the vehicle body and connected with the control unit 12. The first projection module 133 projects a second projection area right behind the center point of the rear tire of the vehicle body. The distance between the center point of the second projection area and the center point of the tire is between 0.4m and 4m.

[0054] The first projection module 133 can include a laser emitter and an optical lens group. The laser emitted by the laser emitter is processed by the optical lens group and forms a second projection area on the ground. The second projection area can be a triangular, rectangular or other geometric shape of light spot, which is used to remind the rear vehicle or pedestrian that there is a two-wheeled vehicle in front. The projection height of the first projection module 133 can be adjusted according to actual needs, and the projection angle can also be adjusted according to actual conditions to ensure that the second projection area can be clearly displayed on the ground.

[0055] In the embodiment, when the vehicle body is in the state of driving along the first direction, or the state of braking and parking, or the state of parking, the control unit 12 controls the first projection module 133 to generate the second projection area according to the collection signal. Specifically, when the collection unit 11 detects that the vehicle body is in the state of straight driving, braking or parking, the control unit 12 controls the first projection module 133 to be turned on and project the second projection area on the ground behind the vehicle body, so as to remind the rear vehicle or pedestrian that there is a two-wheeled vehicle in front. In this case, the second projection area is taken as the first projection area.

[0056] When the distance between the vehicle body and the obstacle is within the preset range, the control unit 12 controls the first projection module 133 to generate the second projection area according to the detection signal. Specifically, when the detection unit 14 detects that there is an obstacle behind the vehicle body, and the distance between the obstacle and the vehicle body is within the preset range (for example, less than 5m), the control unit 12 controls the first projection module 133 to be turned on, and the second projection area A1 is projected on the ground behind the vehicle body, as shown in FIG. 2, so as to remind the rear obstacle (such as a vehicle or a pedestrian) that there is a two-wheeled vehicle in front. In this case, the second projection area is taken as the first projection area. Figure 2

[0057] It should be noted that the projection height of the first projection module 133 is between 0.2m and 1m, the projection horizontal angle is between 30 degrees and 60 degrees (centered on the first projection module 133), and the projection vertical angle is inclined downward by 5 degrees to 15 degrees (relative to the horizontal plane). The projection height in the embodiment is the distance of the vertical projection of the light spot to the ground.

[0058] Further, the projection unit 13 can further include a second projection module 132.

[0059] ​The second projection module 132 is arranged on both sides of the front end of the seat and is connected to the control unit 12. The second projection module 132 projects a third projection area on both sides of the center point of the rear tire of the vehicle body. The distance between the center point of the third projection area and the center point of the second projection area is between 0.4m and 4m.

[0060] The second projection module 132 includes two laser emitters and corresponding optical lens groups, which are respectively installed on the left and right sides of the front end of the seat. The left laser emitter is used to project a third projection area on the ground on the left side of the vehicle body, and the right laser emitter is used to project a third projection area on the ground on the right side of the vehicle body. The third projection area can be an arrow-shaped light spot, which is used to indicate the steering intention of the two-wheeled vehicle 1. The projection height of the second projection module 132 can be adjusted according to actual needs, and the projection angle can also be adjusted according to actual conditions to ensure that the third projection area can be clearly displayed on the ground.

[0061] In the case where the vehicle body is in a state of driving in the second direction, the control unit 12 controls the second projection module 132 to generate the third projection area consistent with the second direction according to the collection signal. Specifically, when the collection unit 11 detects that the vehicle body is in a left turning state, the control unit 12 controls the left laser emitter in the second projection module 132 to be turned on, as shown in Figure 2 , a third projection area A2 is projected on the ground on the left side of the vehicle body, indicating the left turning intention of the two-wheeled vehicle 1. In this case, the third projection area is used as the first projection area.

[0062] In the case where the vehicle body is in a state of driving in the third direction, the control unit 12 controls the second projection module 132 to generate the third projection area consistent with the third direction according to the collection signal. Specifically, when the collection unit 11 detects that the vehicle body is in a right turning state, the control unit 12 controls the right laser emitter in the second projection module 132 to be turned on, as shown in Figure 2 , a third projection area A3 is projected on the ground on the right side of the vehicle body, indicating the right turning intention of the two-wheeled vehicle 1. In this case, the third projection area is used as the first projection area.

[0063] When the distance between the vehicle body and the obstacle is within the preset range, the control unit 12 controls the second projection module 132 to generate the third projection area according to the detection signal. Specifically, when the detection unit 14 detects an obstacle on the left or right side of the vehicle body, and the distance between the obstacle and the vehicle body is within the preset range (for example, less than 3 meters), the control unit 12 controls the laser emitters of the corresponding side of the second projection module 132 to be turned on, and projects a third projection area on the ground on the corresponding side of the vehicle body, to remind the side obstacle (such as a vehicle or a pedestrian) of the presence of the two-wheeled vehicle. In this case, the third projection area is taken as the first projection area. It should be noted that the projection height of the second projection module 132 is between 0.2m and 1.4m, the projection horizontal angle is between 45 degrees and 75 degrees, and the projection vertical angle is inclined downward by 10 degrees to 20 degrees.

[0064] By way of example but not limitation, when the projection height of the second projection module 132 and the first projection module 133 is 0.4m-0.6m, the projection horizontal angle is between 30 degrees and 60 degrees, and the projection vertical angle is inclined downward by 10 degrees to 15 degrees, the third projection area generated by the second projection module 132 can be spliced with the second projection area generated by the first projection module 133 to form a whole projection area, as shown in Figure 3 which can significantly enhance the recognition efficiency of the rear vehicle and reduce the risk of collision, especially at night or in low-light environments.

[0065] Further, the projection unit 13 can further include:

[0066] Referring to Figure 2 the third projection module 131 is arranged at the front end of the vehicle body, and the third projection module 131 projects a fourth projection area A4 directly in front of the center point of the front tire of the vehicle body, and the distance between the center point of the fourth projection area and the center point of the front tire is between 0.4m and 4m.

[0067] In this embodiment, the third projection module 131 can include a laser emitter and an optical lens group. The laser emitted by the laser emitter is processed by the optical lens group to form a fourth projection area on the ground. The fourth projection area can be a circular or other geometric shape of a light spot, which is used to remind the front pedestrian or vehicle of the presence of the two-wheeled vehicle behind. The projection height of the third projection module 131 can be adjusted according to actual needs, and the projection angle can also be adjusted according to actual conditions, so that the fourth projection area can be clearly displayed on the ground. The fourth projection area can be taken as the first projection area. In actual application, the third projection module 131 can be installed on the front part of the vehicle body, or can be installed on the side-view mirrors of the vehicle body respectively.

[0068] It should be noted that the projection height of the third projection module 131 is between 0.2m-1.5m, the projection horizontal angle is between 30 degrees-60 degrees, and the projection vertical angle is inclined downward between 5 degrees-15 degrees.

[0069] The two-wheeled vehicle 1 provided in the embodiment can project different light spots on the ground according to the driving state of the vehicle body and the surrounding environment, remind surrounding vehicles and pedestrians of the existence and driving intention of the two-wheeled vehicle, and improve the driving safety of the two-wheeled vehicle by setting the collecting unit 11, the projection unit 13, the detection unit 14 and the control unit 12 on the vehicle body. At the same time, the projection area is composed of at least three non-collinear light spots, forming a more visually striking prompt effect, further enhancing the effect of safety prompting.

[0070] It should be noted that the control logic (control logic in the control unit 12) involved in the present application can be considered as known prior art.

[0071] Embodiment two

[0072] The two-wheeled vehicle 1 provided in the embodiment is basically the same as that in embodiment one, except that:

[0073] The projection height of the first projection module 133 is between 0.5m-1m, and the projection horizontal angle is between 30°-45°. Specifically, the first projection module 133 is installed at a position with a height of 0.5m-1m at the tail of the vehicle body, and the projection horizontal angle is 30°-45°, so as to ensure that the second projection area can be clearly displayed on the ground 0.4m-4m behind the vehicle body.

[0074] The projection height of the second projection module 132 is between 0.3m-1.2m, and the projection horizontal angle is between 40°-50°. Specifically, the second projection module 132 is installed at a position with a height of 0.3m-1.2m at the front end of the vehicle seat on both sides, and the projection horizontal angle is 40°-50°, so as to ensure that the third projection area can be clearly displayed on the ground 0.4m-4m on both sides of the vehicle body.

[0075] The projection height of the third projection module 131 is between 0.6m-1.5m, and the projection horizontal angle is between 30°-40°. Specifically, the third projection module 131 is installed at a position with a height of 0.6m-1.5m at the front end of the vehicle body, and the projection horizontal angle is 30°-40°, so as to ensure that the fourth projection area can be clearly displayed on the ground 0.4m-4m in front of the vehicle body.

[0076] By optimizing the projection height and projection angle of the projection module, it can be ensured that the projection area can be clearly visible under different environmental conditions, and the effect of safety prompting is improved.

[0077] Considering that the existing two-wheeled vehicle warning system lacks intelligence, cannot be linked with sensors such as radars, cannot automatically adjust the warning mode according to the surrounding environment and obstacle conditions, and cannot actively prevent collision accidents, the application can effectively detect the potential collision risk of the rear vehicle and the electric vehicle by combining the detection unit 14 with the projection unit 13, thereby significantly improving the safety of the two-wheeled electric vehicle. The existing projection warning technology is mainly applied to four-wheeled motor vehicles, and there is little research on projection warning systems for the special structure and use scene of two-wheeled vehicles, which is difficult to meet the safety needs of two-wheeled vehicles in complex traffic environments. The application uses a 77GHz transceiver-disposed frequency-modulated continuous wave (FMCW) short-range millimeter wave radar sensor as the detection unit 14, combined with a radar system based on collision time, which can effectively detect the potential collision risk of the rear vehicle and the electric vehicle, thereby significantly improving the safety of the two-wheeled electric vehicle. By setting the projection device, a dynamically switchable pattern is formed on the ground, and the projection mode is dynamically switched according to different working modes, such as three lights flashing simultaneously in the radar warning mode, single light flashing and then constant light or three lights flashing synchronously in the brake mode, the projection light switches to the corresponding direction arrow in the steering mode, and the projection light runs with a breathing dynamic effect in the normal mode, realizing the integration of functions, and a single system can realize multiple functions such as steering prompt, brake warning, and radar warning. At the same time, the system has strong adaptability and can automatically switch single light / three light schemes according to vehicle configuration, with high compatibility. In addition, parameterized control optimization can optimize energy consumption, and the breathing dynamic effect takes into account aesthetics and low power consumption, achieving the goal of energy efficiency. Compared with the prior art, the dynamic warning projection lamp of the application significantly enhances the recognition efficiency of the rear vehicle and reduces the collision risk.

[0078] It should be noted that both embodiment one and embodiment two are a kind of two-wheeled vehicle.

[0079] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the application, and not to limit them; although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the utility model.
