Description

Technical Field

[0001] This utility model relates to the field of warning light technology, and in particular to a warning light projection device for blind spots when reversing commercial vehicles. Background Technology

[0002] Commercial vehicles have complex body structures, such as long wheelbases in semi-trailers, cargo areas that obstruct the driver's view, and high driver's seats that limit the driver's field of vision. This results in large blind spots when reversing, and large commercial vehicles in cities account for a high proportion of traffic accidents caused by blind spots, posing significant safety hazards.

[0003] However, in existing technologies, traditional commercial vehicle reversing warning systems mostly use radar sensors or cameras for detection and warning. The detection accuracy is greatly affected by environmental interference, the ability to identify objects with low reflectivity is weak, and it cannot provide intuitive spatial location information, which affects the effectiveness of reversing blind spot warning. Utility Model Content

[0004] The purpose of this invention is to address the problems in existing technologies that primarily use radar sensors or cameras for detection and early warning, which suffer from high accuracy affected by environmental interference, weak ability to identify objects with low reflectivity, and inability to provide intuitive spatial location information, thus affecting the effectiveness of blind spot warning when reversing. The proposed invention is a blind spot warning light projection device for commercial vehicles reversing.

[0007] Preferably, one end of the laser emitting module passes through the outer wall of the mounting base and is movably connected to the inner wall of the mounting block, and the driven gear is sleeved on the outside of the laser emitting module.

[0008] Preferably, a lens is fixedly connected to the inner wall of the mounting block, and the lens is disposed at the front end of the laser emitting module.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a rear blind spot warning light projection device for commercial vehicles, including a light projection head 1. A connecting seat 2 is installed at one end of the light projection head 1, and a controller 3 is installed on one side of the connecting seat 2. A light emission port 11 is embedded in the outer wall of the light projection head 1. A fixing block 12 is fixedly connected to the outer wall of the other end of the light projection head 1. A millimeter-wave radar 13 is embedded in the outer wall of the fixing block 12. The connecting seat 2 includes a mounting base 21, a mounting block 22, a motor 23, a drive gear 24, and a driven gear 25. The motor 23 is embedded in the side wall of the mounting base 21. One end of the driven gear 25 is fixedly connected to the outer wall of the mounting block 22, and the other end of the driven gear 25 is rotatably connected to the outer wall of the mounting base 21. The drive gear 24 is fixedly connected to the output shaft end of the motor 23, and the drive gear 24 and the driven gear 25 are meshed together.

[0023] The specific settings and functions of this embodiment are described in detail below. The light emission port 11 on the outer wall of the light projection head 1 is used to project the warning light signal to the ground in a directional manner, forming a visual blind spot warning area, which directly prompts surrounding traffic participants to avoid the blind spot. The millimeter-wave radar 13 embedded on the fixing block 12 is the core environmental perception component, which can detect the distance, speed and direction of moving objects behind the vehicle in real time. The detection data is transmitted to the controller 3 in real time to provide a basis for warning decision. The mounting base 21 provides a fixed foundation for the entire connecting base. The motor 23 drives the active gear 24 to rotate. Through the meshing transmission with the driven gear 25, it drives the mounting block 22 and the light projection head 1 connected to it to achieve an angle rotation within a range of ±30°. The projection angle can be dynamically adjusted according to the reversing direction of the vehicle or the length of the vehicle body to ensure that the warning area always covers the actual blind spot.

[0024] Example 2: Figure 1 - Figure 4 As shown, a connecting pipe 32 is fixedly connected to one side of the controller 3. A laser emitting module 33 is installed on the inner wall of the connecting pipe 32. One end of the laser emitting module 33 passes through the outer wall of the mounting base 21 and is movably connected to the inner wall of the mounting block 22. A driven gear 25 is sleeved on the outside of the laser emitting module 33. A lens 27 is fixedly connected to the inner wall of the mounting block 22. The lens 27 is located at the front end of the laser emitting module 33. An insertion slot 26 is opened on the outer wall of the mounting block 22. A connecting block 14 is fixedly connected to one end of the light projection head 1. The connecting block 14 is inserted into the inner wall of the insertion slot 26. The interior of the light projection head 1 is connected to the interior of the mounting block 22. A refractive lens 15 is installed on the inner side wall of the light projection head 1. A power interface 31 is fixedly connected to the outer wall of the tail end of the controller 3.

[0025] The overall effect of this embodiment is that the laser emitting module 33 is integrated between the controller 3 and the mounting block 22 through the connecting pipe 32, providing a high-brightness, highly directional laser light source, providing a stable light source foundation for ground warning graphics. The lens 27 is set at the front end of the laser emitting module 33, which can focus or diffuse the laser. Together with the refractive lens 15 on the inner side wall of the light projection head 1, it forms a specific light path, so that the laser is projected through the light emission port 11 to form a regular and clear warning pattern. The plug-in slot 26 of the mounting block 22 and the connecting block 14 of the light projection head 1 adopt a plug-in design, which not only ensures the connectivity of the internal light paths of the two, but also facilitates quick disassembly and replacement of light projection heads 1 of different specifications, improving the versatility and maintenance convenience of the device. The power interface 31 at the tail end of the controller 3 is directly connected to the vehicle's 12V / 24V power supply to ensure a stable power supply for components such as the laser emitting module 33, the motor 23, and the millimeter-wave radar 13. At the same time, the controller 3 realizes the coordinated control of each component through its built-in circuit.

[0026] The device's operation and working principle are as follows: Millimeter-wave radar 13 continuously scans the vehicle's rear blind spot, transmitting data such as the distance and speed of detected obstacles to controller 3 in real time. Controller 3 analyzes the radar data; if a collision risk is determined, such as when the obstacle distance is less than 5 meters, the drive motor 23 operates: the active gear 24 drives the driven gear 25 to rotate, adjusting the mounting block 22 and the light projection head 1 to the target angle; controller 3 simultaneously activates the laser emission module 33, and the laser, after being focused by lens 27, enters the light projection head 1. The light path is adjusted by the refractive lens 15, and finally projected onto the ground from the light emission port 11, forming a dynamic warning pattern matching the blind spot; if the risk level increases, controller 3 can link the vehicle's CAN bus with the in-vehicle buzzer or seat vibration device to simultaneously issue multiple warnings to the driver.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
