[0053] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0054] In order to implement vehicle warnings in various ways, the following technical solutions in the embodiments of the present invention may be adopted.

[0055] In one embodiment of the present invention, the vehicle warning system includes a base 10 , a control block 20 , a laser projector 30 , and a light sensor 40 .

[0056] The base 10 is movably connected to the vehicle. As an example, the base 10 is movably connected to the vehicle body through a bracket. As another example, the base 10 is adsorbed on the vehicle body through a suction cup to achieve movably connected to the vehicle.

[0057] The control block 20 is fixedly mounted on the base 10 . The laser projector 30 is rotatably connected to the control block 20 . The light sensor 40 is fixed to the control block 20 .

[0058] The control block 20 receives and responds to the operation instruction signal, triggers the light sensor 40 to measure the ambient brightness; based on the ambient brightness, adjusts the luminous intensity of the laser projector 30 and regulates the projection position of the laser projector 30 on the ground.

[0059] The following is an illustrative description of the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. Figure 1 , Figure 1 FIG. 1 is a schematic structural diagram of a vehicle warning system according to an embodiment of the present invention. Figure 1 That is, 100:

[0060] The vehicle warning system includes a base 10 , a control block 20 , a laser projector 30 and a light sensor 40 .

[0061] The control block 20 includes: a special-shaped support structure with a receiving space and a controller encapsulated in the special-shaped support structure. Figure 1 The controller is connected to the laser projector 30 and the light sensor 40 for signal signals.

[0062] The laser projector 30 is disposed within the accommodation space of the control block 20 and is rotatably connected to the special-shaped support structure via a rotating shaft. This allows the laser projector 30 to be adjusted in pitch relative to the base. As an example, considering the penetrability of light in inclement weather, the laser projector 30 uses a red light source and / or a yellow light source. As another example, the power of the laser projector 30 is 500mW to 1W. The laser projector 30 emits a laser with a wavelength of 850nm to 940nm. The laser projector 30 can use a narrow-beam lens for focused projection.

[0063] The controller receives and responds to the operation instruction signal, triggering the light sensor 40 to measure the ambient brightness. Based on the ambient brightness, it adjusts the luminous intensity of the laser projector 30. The controller also drives the shaft to adjust the pitch angle of the laser projector 30 to control the projection position of the laser beam on the ground. For example, the projection distance of the laser beam on the ground is equal to the product of the tangent of the pitch angle and the height of the vehicle warning system above the ground.

[0064] As an example, the controller processes the operation instruction signal via a control circuit board. The control circuit board integrates a microcontroller unit (MCU), power management, and a communication interface, such as a CAN / LIN bus.

[0065] In one embodiment of the present invention, a vehicle warning system is provided with a power supply. For example, the vehicle warning system is electrically connected to a vehicle to enable information exchange with the vehicle. A driver sends an operation instruction signal from within the vehicle. The vehicle warning system receives the operation instruction signal from the vehicle via control block 20.

[0066] See also Figure 2 , Figure 2 FIG. 4 is a schematic structural diagram of another vehicle warning system according to an embodiment of the present invention.

[0067] The bottom of the base 10 is provided with first assembly parts distributed in an annular manner.

[0068] The output shaft of the rotation control motor 11 is provided with a second assembly member that mates with the first assembly member. The first and second assembly members are detachably connected. In one example, the first assembly member includes a tooth groove, and the second assembly member includes a protruding tooth that meshes with the tooth groove. In another example, the first assembly member includes a protruding tooth, and the second assembly member includes a tooth groove that meshes with the protruding tooth.

[0069] The control block 20 controls the rotation control motor 11 to drive the base 10 to rotate to a preset azimuth angle according to the operation instruction signal.

[0070] And / or, the vehicle warning device system further includes: a pitch control motor 31. The pitch control motor 31 controls the rotation of the rotating shaft.

[0071] The control block 20 receives and responds to the operation instruction signal to control the pitch control motor 31 to adjust the pitch angle of the laser projector 30 through the rotating shaft to adjust the projection position of the laser projector on the ground.

[0072] In one embodiment of the present invention, the vehicle warning system receives an operation instruction signal sent by the vehicle through the control block 20. Furthermore, the base 10 can be rotated to a preset azimuth angle, and the pitch angle of the laser projector 30 can be adjusted to adjust the projection distance of the laser beam on the ground.

[0073] The azimuth angle is the angle of the base 10 relative to the vehicle's transverse axis. Rotation of the base 10 is achieved using the rotation control motor 11. The pitch angle is the angle of the laser projector 30 relative to the vehicle's longitudinal axis. The pitch control motor 31 controls the pitch of the laser projector 30.

[0074] Continue to see Figure 2 The vehicle warning system further includes a warning light source 50 and a speaker 60 arranged on the upper surface of the control block 20.

[0075] The control block 20 adjusts the brightness of the warning light source 50 and the output volume of the speaker 60 based on the ambient brightness. For example, if the ambient brightness is dark, the brightness of the warning light source 50 is adjusted to maximum brightness and the volume of the speaker 60 is adjusted to maximum output volume. For example, the brightness of the warning light source 50 is above 50,000 cd and supports pulse width modulation (PWM) dimming to control the flashing frequency. The maximum volume of the speaker 60 is 100 decibels. The speaker 60 supports playing voice files in pre-set formats.

[0076] In one embodiment of the present invention, considering the penetrability of light in severe weather, the warning light light source 50 adopts one or more of a red light source, a yellow light source, and a blue light source.

[0077] Continue to see Figure 2 The vehicle alarm system further includes a protective housing 70 made of a transparent material. The protective housing 70 is used to protect the components inside the vehicle alarm system. As an example, the protection grade of the protective housing 70 is IP67 to prevent rain and dust from entering the interior of the vehicle alarm system.

[0078] The protective housing 70 is sealed and connected to the control block 20 and encloses a sealed space. The warning light source 50 and the speaker 60 are located in the sealed space. In order to ensure the light transmittance of the warning light source 50, the protective housing is made of a transparent material. Figure 3 , Figure 3 Schematic diagram of the protective housing 70 according to an embodiment of the present invention.

[0079] Furthermore, in order to ensure that the speaker 60 can output sound normally, a plurality of through holes are provided in the area of ​​the protective housing 70 corresponding to the speaker 60 .

[0080] In one embodiment of the present invention, the vehicle warning device system is arranged at one or more of the following locations: the upper left of the rear of the vehicle, the upper right of the rear of the vehicle, the rear of the vehicle luggage rack and above the rear bumper.

Figure 4 In the embodiment, one vehicle warning system A is positioned at the upper left side of the vehicle's rear end, and the other vehicle warning system A is positioned at the upper right side of the vehicle's rear end, thereby avoiding obstructions such as exhaust pipes and bumpers. As an example, the vehicle warning systems are positioned at a height of at least 1.5 meters above the ground to ensure that the laser projector 30 is not obstructed by tire splash water.

[0085] It should be noted that the image projected onto the ground by the laser beam of laser projector 30 may include a warning sign and / or a position indicator line. The position indicator line serves to mark the edge of the image. As an example, the wavelength of the position indicator line falls within the non-visible light wavelength range, thereby preventing the position indicator line from interfering with the image projected onto the ground.

[0086] In one embodiment of the present invention, see Figure 2 The vehicle warning system further includes a laser tracker 80. The laser tracker 80 is fixedly mounted on the surface of the control block 20, and the axis of the laser tracker 80 is parallel to the optical axis of the laser projector 30. The laser tracker 80 is used to detect the position indicator line to achieve the splicing of multiple images.

[0087] The vehicle is provided with a plurality of vehicle warning systems. The laser tracker 80 provides the control block 20 with a position indication line of its adjacent vehicle warning systems.

[0088] The control block 20 regulates the base 10 and / or the laser projector 30 based on the position indication line, so that the images projected by the plurality of laser projectors 30 are spliced.
