[0033] Referring to Figures 1 - 10 , an anti - collision warning device for vehicles based on visual analysis includes a fixed seat 3, and further includes a protection part. The protection part includes an outer shell 2, a connection ring 5 and an annular groove 6. The connection ring 5 is fixedly installed on the fixed seat 3, the annular groove 6 is opened on the outer shell 2, and the annular groove 6 is matched with the connection ring 5. The connection ring 5 can slide in the annular groove 6. Therefore, the connection between the outer shell 2 and the fixed seat 3 is a slidable connection. This connection method can, when the outer shell 2 is impacted, reduce the impact force on the internal components of the outer shell 2 by using its movement relative to the fixed seat 3, thereby playing a certain protective effect on the internal components.
[0034] A plurality of sliders 7 are fixedly installed on the side wall of the connecting ring 5. A plurality of chutes 8 that cooperate with the corresponding sliders 7 are provided on the side wall of the annular groove 6. A spring 9 is installed between each chute 8 and the corresponding slider 7. With the cooperation of the slider 7 and the chute 8, the moving direction of the connecting ring 5 in the annular groove 6 can be limited, making the moving direction of the outer shell 2 relative to the fixed seat 3 stable. Under the elastic force of the spring 9, when the outer shell 2 is not impacted, its position relative to the fixed seat 3 can be kept stable. An anti-slip pad that adheres to the chute 8 is fixedly installed on the side wall of the slider 7. The design of the anti-slip pad can further improve the stability of the outer shell 2 when it is not impacted. At the same time, when the outer shell 2 is impacted, the anti-slip pad can cooperate with the spring 9 to buffer the impact force received by the outer shell 2, further improving the protection effect on the internal components.
[0035] A stability detection part, the stability detection part includes a vision probe 26 and a stability plate 13. The stability plate 13 is installed in the fixed seat 3 through a plurality of shock absorption components. The shock absorption component is composed of an arc-shaped block 14, an arc-shaped groove, an arc-shaped rod 16 and two compression springs 15. The arc-shaped block 14 is fixedly installed on the side wall of the stability plate 13. The arc-shaped groove is provided on the side wall of the fixed seat 3, and the arc-shaped groove cooperates with the arc-shaped block 14. The arc-shaped rod 16 is fixedly installed in the arc-shaped groove, and the arc-shaped rod 16 is in sealed sliding cooperation with the arc-shaped block 14. The two compression springs 15 are respectively installed between the two ends of the arc-shaped block 14 and the arc-shaped groove. The cooperation of the arc-shaped rod 16 and the arc-shaped groove enables the stability plate 13 to rotate at a certain angle in the vertical direction in the fixed seat 3. The design of the compression spring 15 can keep the installation angle of the stability plate 13 on the fixed seat 3 constant when the stability plate 13 is not affected by external forces. Through the design of the arc-shaped rod 16, the moving resistance of the arc-shaped block 14 in the arc-shaped groove can be increased, so that during driving, the shock absorption effect of the stability plate 13 in the fixed seat 3 can be improved, making the vision probe 26 installed on it work more stably.
[0036] The vision probe 26 is installed on the stability plate 13 through a stability component. The stability component is composed of a rotating groove 17, a rotating shaft 18, a mounting frame 22, a connecting block 23 and a connecting shaft 24. The rotating groove 17 is provided on the stability plate 13. The rotating shaft 18 is rotatably installed in the rotating groove 17. The mounting frame 22 is fixedly installed on the rotating shaft 18. The connecting block 23 is fixedly installed on the vision probe 26. The connecting shaft 24 is rotatably installed in the mounting frame 22, and the connecting shaft 24 is fixedly connected to the connecting block 23. Figure 3 Taking the left view direction as an example, under the action of the rotating shaft 18 and the connecting shaft 24, the vision probe 26 can rotate in the horizontal direction and the left and right directions on the stability plate 13, so that when going uphill and downhill and making left and right turns, the vision probe 26 can maintain a horizontal forward state.
[0037] A deceleration washer one 19 that mates with the rotating shaft 18 is fixedly installed in the rotating groove 17. Two deceleration washers two 25 that mate with the connecting shaft 24 are fixedly installed in the mounting frame 22. A counterweight one 20 is fixedly installed at the bottom of the rotating shaft 18. A swinging groove 21 that mates with the counterweight one 20 is fixedly installed on the side wall of the rotating groove 17. A counterweight two 27 is fixedly installed at the bottom of the connecting block 23. With the cooperation of the deceleration washer one 19, the counterweight one 20, the deceleration washer two 25, and the counterweight two 27, the angle of the vision probe 26 can be automatically controlled according to the driving state, and the angle change of the vision probe 26 caused by the jitter during driving can be reduced, effectively ensuring the stability of the vision probe 26.
[0038] A protection component that mates with the vision probe 26 is installed between the outer shell 2 and the connecting ring 5. The protection component consists of an inflatable bag 12, a piston ring 11, multiple fixing rods 10, and multiple air holes. The inflatable bag 12 is fixedly installed in the outer shell 2, and the inflatable bag 12 is circular. The inner diameter of the inflatable bag 12 is smaller than the diameter of the vision probe 26. The piston ring 11 is hermetically slidably installed in the annular groove 6. Multiple fixing rods 10 are fixedly installed between the piston ring 11 and the connecting ring 5. Multiple air holes are opened between the inflatable bag 12 and the annular groove 6. When the outer shell 2 is impacted, it moves relative to the fixed seat 3 under the action of an external force. During this process, the piston ring 11 moves into the annular groove 6, and the inflatable bag 12 is inflated through multiple air holes, causing it to expand and unfold, holding the vision probe 26 inside the outer shell 2 and preventing the vision probe 26 from being damaged under the impact force.
[0039] An alarm interaction unit. The alarm interaction unit includes a master control module 28 fixedly installed in the fixed seat 3. The master control module 28 consists of a speed measurement module, a distance measurement module, an angle measurement module, an impact module, an analysis module, and an interaction module. The speed measurement module is used to detect the vehicle speed. The distance measurement module is used to detect the distance to an obstacle. The angle measurement module is used to detect the straight-line angle between the obstacle and the driving direction. The impact module is used to detect the impact force. The analysis module is used to analyze and calculate the detection data of the speed measurement module, the distance measurement module, the angle measurement module, and the impact module. The interaction module includes a speaker, a vehicle-mounted horn, a vehicle-mounted brake, and a vehicle-mounted power supply. Among them, the speaker is powered by the vehicle-mounted power supply. The master control module 28 is electrically connected to the vision probe 26, the speaker, the vehicle-mounted horn, the vehicle-mounted brake, and the vehicle-mounted power supply. The interaction module is used to perform voice interaction with the driver according to the data analysis result of the analysis module and send an alarm signal to the outside, reducing the possibility of impact and improving driving safety. At the same time, the cost of this device is lower than that of the vehicle-mounted radar system, and the installation difficulty and installation space requirements are smaller. At the same time, it is not affected by other radar signals.
[0040] The speed measurement module can use a speed sensor, the distance measurement module can use a distance sensor, the angle measurement module can use an angle sensor, and the impact module can use an impact sensor. All of the above can use existing products or combinations of existing technologies, so the specific structure will not be elaborated here.
[0041] The fixed seat 3 is fixedly installed at the front end of the vehicle through the connecting seat 1. A rain and light shield 4 is fixedly installed on the side wall of the outer shell 2. The outer shell 2 is made of a transparent material. The rain and light shield 4 can block rainwater. At the same time, when the fixed seat 3 is installed near the vehicle headlight, the rain and light shield 4 can also block the light source emitted by the headlight, avoiding the influence of the light on the detection effect of the vision probe 26 during night driving.
[0042] The impact module is internally provided with an alarm unit. The alarm unit consists of an emergency button, an independent power supply unit, and a GPS positioning unit. The emergency button is signal-connected to the traffic control center dispatching system through the Internet of Things. When the impact force monitored by the alarm unit exceeds the upper limit, the independent power supply unit is activated, causing the emergency button to send an alarm signal and the vehicle position information to the traffic control center dispatching system, ensuring that the traffic control center can promptly learn about the situation after a traffic accident, facilitating the handling of the accident and the treatment of the driver. At the same time, the impact module cuts off the vehicle power supply, making the vehicle in a flameout state, avoiding the problem of secondary injuries caused by the driver's misoperation. The positioning error of the GPS positioning unit is less than 0.5 m.
[0043] The master control module 28 analyzes the data detected by the vision probe 26 based on vision analysis technology. By connecting to the GPS system, when the vehicle speed exceeds the speed limit of the section, the master control module 28 automatically controls the operation of the vehicle brake for speed reduction, and at the same time makes the speaker issue a voice prompt to the driver about the risk of speeding to ensure safe driving. The safe distance of the ranging module is the braking distance of the vehicle, which is calculated by the system according to the vehicle speed. The specific calculation method is prior art and will not be elaborated here. When the distance between the vehicle and the obstacle is less than the safe distance, the master control module 28 automatically controls the operation of the vehicle horn and the vehicle brake to prompt the vehicle in front or pedestrians, and makes the speaker issue a voice prompt to the driver so that the driver can timely discover the obstacle ahead and make preparations. The safe angle of the angle measuring module is 25°. The angle measuring module is equipped with an intelligent learning system, which can adjust the safe angle according to the driving habits of the driver and big data statistics, so that the vehicle can pass the obstacle at a safe straight angle to avoid collisions. When the straight angle between the vehicle and the obstacle is less than the safe angle, the master control module 28 automatically controls the operation of the vehicle horn and the vehicle brake, and at the same time makes the speaker issue a voice prompt to the driver. When a collision occurs to the vehicle and the impact force is greater than the threshold value (the threshold value is set by the system according to the self-weight of different vehicle models and will not be specifically elaborated here), the master control module 28 automatically controls the vehicle power supply to cut off. After the power is cut off, the problem of secondary injuries caused by the driver's misoperation can be avoided, which is more secure.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
