Description

Technical Field

[0001] This invention relates to the field of automotive safety assistance technology, specifically to an intelligent vehicle collision avoidance device and method in rain and fog environments. Background Technology

[0002] Vehicle collision avoidance is an active safety technology that uses sensors such as radar and cameras to detect the vehicle's surroundings in real time. When a potential collision risk is detected, the system will automatically issue a warning and take measures such as braking and steering to avoid an accident.

[0003] A search revealed a Chinese patent with patent number CN211391171U, which discloses a vehicle intelligent collision avoidance prediction device. The device includes a mounting plate, an intelligent prediction plate, and a collision avoidance plate. The mounting plate has a mounting groove embedded within it, and magnets are fixedly connected to the upper and lower sides of its back. A buffer plate is fixedly connected to the middle of the back of the mounting plate. The intelligent prediction plate has recesses embedded at its upper and lower ends. This device reduces vibration and friction of the mounting plate through the buffer plate, further protecting the entire device. It monitors the vehicle itself and vehicles in front of or behind it using a speed sensor, and continuously monitors the distance between vehicles using a distance sensor. A rotating shaft drives the collision avoidance plate to rotate and connect, protecting both the device and the vehicle. However, existing vehicle intelligent collision avoidance devices directly use a rotating shaft and a telescopic plate to drive the collision avoidance plate, rotating it out to perform collision avoidance. Although this increases the impact area, the collision avoidance plate and the intelligent prediction plate are only connected by the telescopic plate and the rotating shaft. The connection is weak and the buffering and collision avoidance effect is poor. If the connection breaks, the collision avoidance plate will directly contact and collide with the monitoring equipment on the intelligent prediction plate, thereby causing equipment damage and resulting in losses.

[0012] According to a second aspect of the present invention, a vehicle intelligent collision avoidance method in rain and fog environments is provided, comprising the following steps: SS001. After installing this intelligent vehicle collision avoidance device in rain and fog conditions at the required collision avoidance positions at the front and rear of the vehicle, the monitoring component monitors the vehicle's driving situation. If a collision is about to occur, the limit connection component will disconnect the power. SS002. After the limit connection assembly is de-energized, the connection between cover one and cover two is released, and then the linkage plate is moved to the right in conjunction with the hydraulic telescopic column, thereby moving the anti-collision plate out of cover one and cover two, thus achieving the purpose of anti-collision.

A connecting rotating plate 502 is slidably connected to the inner cavity of the first cover 3 and the second cover 4. The connecting rotating plate 502 is penetrated by the limiting guide arc rod 501 and the two are slidably connected.

[0022] A linkage plate 503 is provided between the two connecting rotating plates 502. The linkage plate 503 and the connecting rotating plate 502 are rotatably connected by a hinge. A crash plate 504 is fixedly connected to one side of the linkage plate 503. A buffer component is provided on one side of the crash plate 504. A connecting groove 505 is provided on the inner wall of both the first cover 3 and the second cover 4. A connecting groove 506 is provided through the side of the linkage plate 503 facing the first connecting groove 505. The second connecting groove 506 extends to the inner wall of the crash plate 504. A hydraulic telescopic column 507 is provided in the cavity formed by the merging of the first connecting groove 505 and the second connecting groove 506. Both sides of the hydraulic telescopic column 507 are rotatably connected to the inner cavities of the first connecting groove 505 and the second connecting groove 506 respectively through a rotating shaft 508.

[0023] The limiting connection assembly includes a connecting groove 3 5011 formed at the joint between cover 1 3 and cover 2 4. An electromagnet 5012 is fixedly connected to the inner cavity of the connecting groove 3 5011. A limiting arc groove 509 is symmetrically formed on the inner wall of the U-shaped limiting seat 1. The limiting arc groove 509 coincides with the rotation path of the rotating plate 2. A limiting post 5010 is slidably connected to the inner cavity of the limiting arc groove 509. The two limiting posts 5010 are fixedly connected to the two ends of the top rotating plate 2 respectively. When the limiting post 5010 is located at the bottom of the inner cavity of the limiting arc groove 509, the rotating plate 2 is in a horizontal state.

[0024] The working principle of this invention is as follows: After installing this intelligent vehicle anti-collision device in rain and fog conditions at the required anti-collision positions at the front and rear of the vehicle, the vehicle's driving situation is monitored through the monitoring component. If a collision is about to occur, the limit connection component is de-energized, and the connection between cover 1 3 and cover 2 4 is released. At the same time, the hydraulic telescopic column 507 in the connecting groove 1 505 and connecting groove 2 506 opens, driving the linkage plate 503 to move to the right. This, in conjunction with the limit guide arc rod 501 in cover 1 3 and cover 2 4, guides the connecting rotating plate 502, which is rotatably connected to the top of the linkage plate 503 via a hinge. Then, under the action of the rotating plate 2, which is rotatably connected to the U-shaped limit seat 1 via the limit shaft 26, cover 1 3 and cover 2 4 rotate in opposite directions, thereby causing the anti-collision plate 504 on one side of the linkage plate 503 to move out of the cavity formed by cover 1 3 and cover 2 4. The connection has high strength, thereby improving the anti-collision effect and ensuring the safety of the monitoring equipment.

[0025] Please see Figure 4In this embodiment of the invention, the monitoring component includes a slot 6 that extends through the outer ring of the cover 3. A mounting shell 7 is fixedly connected to the inner cavity of the slot 6. A distance sensor 8, a speed sensor 9, and a camera 27 are sequentially arranged in the inner cavity of the mounting shell 7. A transparent sealing plate 10 is fixedly connected to the inner cavity of the slot 6. The transparent sealing plate 10 is made of a hydrophobic material.

[0026] The working principle of this invention is as follows: During the monitoring of vehicle driving conditions by the camera 27, speed sensor 9, and distance sensor 8 in the monitoring component, a transparent sealing plate 10 made of hydrophobic material is used to protect the sensing equipment inside the mounting shell 7, preventing moisture from adhering to the surface of the transparent sealing plate 10 in rainy or foggy environments and affecting the normal operation of the sensing equipment; In the event of an accident, the first cover 3 and the second cover 4 rotate, causing the mounting shell 7 in the slot 6 outside the first cover 3 to rotate together, thereby rotating the equipment inside the mounting shell 7 out of the collision area, minimizing damage, while the first cover 3 and the second cover 4 also increase the anti-collision area and improve the anti-collision effect.

[0027] Example 3; Please see Figure 1 and Figure 5 In this embodiment of the invention, the installation mechanism includes an installation plate 11 located on one side of the U-shaped limiting seat 1. An installation hole 12 is provided on one side of the installation plate 11, and an installation groove 13 is provided on the top of the installation plate 11. A connecting plate 14 is slidably connected to the inner cavity of the installation groove 13. The connecting plate 14 is fixedly connected to the U-shaped limiting seat 1. A stabilizing stud 15 is fixedly connected to the inner cavity of the installation groove 13. A stabilizing nut 16 is screwed onto the outer ring of the top of the stabilizing stud 15. The stabilizing stud 15 passes through the connecting plate 14 and the two are slidably connected. A buffer support assembly is provided between the U-shaped limiting seat 1 and the cover 3.

[0028] The working principle of this invention is as follows: When installing this anti-collision device, the mounting plate 11 can be fixed at the required anti-collision position at the front and rear of the vehicle by means of bolts and mounting holes 12 on the mounting plate 11. Then, the connecting plate 14 on one side of the U-shaped limiting seat 1 is inserted into the mounting groove 13 on one side of the mounting plate 11. During the process, the stabilizing stud 15 in the mounting groove 13 will penetrate the connecting plate 14 to achieve a reinforced connection between the connecting plate 14 and the mounting groove 13. Finally, the stabilizing nut 16 is screwed into the outside of the stabilizing stud 15 so that the stabilizing nut 16 and the connecting plate 14 form a compressive force, thereby stably limiting the connecting plate 14 in the mounting groove 13, thus completing the device fixation and improving the convenience and ease of installation of this anti-collision device.

[0029] Example 4; Please see Figure 3 , Figure 6 and Figure 7In this embodiment of the invention, the buffer assembly includes buffer grooves 17 symmetrically opened on one side of the anti-collision plate 504. A buffer block 18 is slidably connected to the inner cavity of the buffer groove 17. A groove 28 is opened on one side of the buffer block 18. A buffer plate 24 is provided on one side of the anti-collision plate 504. A rubber plate 25 is fixedly connected to one side of the buffer plate 24. A U-shaped seat 19 is fixedly connected to the side of the buffer plate 24 facing the anti-collision plate 504.

[0030] An unloading plate 20 is inclined between the U-shaped seat 19 and the groove 28. The two upper unloading plates 20 are distributed in a figure-eight shape. The unloading plates 20 are rotatably connected to the U-shaped seat 19 and the groove 28 through the rotating shaft 21. The inner cavity of the buffer groove 17 is fixedly connected to the limit guide rod 22. The outer ring of the limit guide rod 22 is provided with a buffer spring 23. The two ends of the buffer spring 23 are respectively connected to the buffer groove 17 and the buffer block 18. The buffer spring 23 is always in a compressed state.

[0031] The buffer support assembly includes a U-shaped seat 29 fixedly connected to one side of the cover 3 and the cover 4 and the top of the U-shaped limiting seat 1. The U-shaped seats 29 are connected by a telescopic buffer rod 30. The inner cavity of the telescopic buffer rod 30 is provided with a spring. The telescopic buffer rod 30 is rotatably connected to the U-shaped seat 29 through a rotating shaft 31.

[0032] The working principle of this invention is as follows: After the anti-collision plate 504 moves out of the cavity formed by the first cover 3 and the second cover 4, if an impact occurs, the impact force will first act on the rubber plate 25, and then the impact force will be transmitted to the buffer plate 24. At this time, the unloading plate 20 between the U-shaped seat 19 and the buffer block 18 will rotate under the action of the second rotating shaft 21. During the process, the unloading plate 20 will push the buffer block 18 in the buffer groove 17 to move to both ends and compress the buffer spring 23, thereby buffering the impact force generated by the collision. If the impact force is large and the force acts on the first cover 3 and the second cover 4, the telescopic buffer rod 30 between the second U-shaped seat 29 will be compressed under the action of the rotating shaft 31, thereby further buffering the impact force and improving the anti-collision effect of this anti-collision device.

[0033] Specifically, a vehicle intelligent collision avoidance method in rain and fog environments includes the following steps: SS001. After installing this intelligent vehicle collision avoidance device in rain and fog conditions at the required collision avoidance positions at the front and rear of the vehicle, the monitoring component monitors the vehicle's driving situation. If a collision is about to occur, the limit connection component will disconnect the power. After the limit connection assembly is de-energized, the connection between cover 1 3 and cover 2 4 is released, and then the linkage plate 503 is driven to move to the right in conjunction with the hydraulic telescopic column 507, thereby moving the anti-collision plate 504 out of cover 1 3 and cover 2 4, so as to achieve the purpose of anti-collision. SS003. During vehicle operation, the monitoring component monitors the vehicle's driving status and controls the anti-collision mechanism 5, enabling the linkage plate 503 to move smoothly and allowing the equipment inside the mounting housing 7 to move out of the collision area, reducing losses while improving the anti-collision effect. After SS004 and anti-collision plate 504 are removed, they work with the buffer assembly to buffer the impact force generated by the collision. If the impact force is large and the force is applied to cover 3 and cover 4, the buffer support assembly is used to further buffer the impact force. SS005. When installing this anti-collision device, first fix the mounting plate 11 in the anti-collision position by bolting it into the mounting hole 12, and then insert the U-shaped limit seat 1 into the mounting groove 13 in the mounting plate 11 to complete the installation of this anti-collision device.

[0034] Working Principle: After installing this intelligent vehicle anti-collision device in rain and fog conditions at the required anti-collision positions at the front and rear of the vehicle, the monitoring component monitors the vehicle's driving situation. If a collision is imminent, the limit connection component is de-energized, and the connection between cover 1 3 and cover 2 4 is released. At the same time, the hydraulic telescopic column 507 in the connecting groove 1 505 and connecting groove 2 506 opens, driving the linkage plate 503 to move to the right. This, in conjunction with the limit guide arc rod 501 in cover 1 3 and cover 2 4, guides the connecting rotating plate 502, which is rotatably connected to the top of the linkage plate 503 via a hinge. Then, under the action of the rotating plate 2, which is rotatably connected to the U-shaped limit seat 1 via the limit shaft 26, cover 1 3 and cover 2 4 rotate in opposite directions, causing the anti-collision plate 504 on one side of the linkage plate 503 to move out of the cavity formed by cover 1 3 and cover 2 4. The connection has high strength, thereby improving the anti-collision effect and ensuring the safety of the monitoring equipment.

8. A vehicle intelligent collision avoidance method in rain and fog environments, implemented using the vehicle intelligent collision avoidance device for rain and fog environments as described in any one of claims 1-7, characterized in that, The method includes the following steps: SS001. After installing this intelligent vehicle collision avoidance device in rain and fog conditions at the required collision avoidance positions at the front and rear of the vehicle, the monitoring component monitors the vehicle's driving situation. If a collision is about to occur, the limit connection component will disconnect the power. SS002. After the limit connection assembly is de-energized, the connection between the first cover (3) and the second cover (4) is released, and then the linkage plate (503) is driven to move to the right in conjunction with the hydraulic telescopic column (507), thereby moving the anti-collision plate (504) out of the first cover (3) and the second cover (4) to achieve the purpose of anti-collision. SS003. During vehicle operation, the vehicle operation is monitored by the monitoring component and the anti-collision mechanism (5) is controlled so that the linkage plate (503) can move smoothly and the equipment in the mounting shell (7) can be moved out of the collision area, reducing losses and improving the anti-collision effect. After the SS004 and anti-collision plate (504) are removed, they are used in conjunction with the buffer assembly to buffer the impact force generated by the collision. If the impact force is large and the force is applied to the first (3) and the second (4) of the cover, the buffer support assembly is used to further buffer the impact force. SS005. When installing this anti-collision device, first fix the mounting plate (11) in the anti-collision position by using bolts to fit the mounting holes (12), and then insert the U-shaped limit seat (1) into the mounting groove (13) in the mounting plate (11) to complete the installation of this anti-collision device.
