Description
Technical Field
[0001] This invention relates to the field of vehicle safety technology, and in particular to an intelligent deceleration and hazard avoidance device for motor vehicles. Background Technology
[0002] In existing technologies, when faced with the risk of a sudden collision, motor vehicles mainly rely on the driver's reaction to brake or on traditional passive protective structures such as bumpers and anti-collision beams. There is a reaction time between the driver's perception of the risk and the application of braking, which can easily lead to missing the best opportunity for avoidance in high-speed or emergency situations. Traditional anti-collision structures mainly absorb energy after a collision, lacking proactive intervention measures before a collision to reduce accidents. Warning systems, braking systems, and physical protective structures are usually independent of each other, lacking an integrated design that automatically triggers multi-level, progressive emergency measures after a warning. Emergency braking may not be sufficient to completely avoid a collision, especially on slippery roads or under heavy loads, where there is a lack of additional, mandatory deceleration or stopping mechanisms. Therefore, there is an urgent need for an integrated device that can intelligently perceive risks, proactively trigger, and execute multi-level deceleration and protective actions. In view of this, this case was developed through in-depth research into the above problems. Summary of the Invention
[0003] The purpose of this invention is to solve the above-mentioned problems by designing an intelligent deceleration and risk avoidance device for motor vehicles, which solves the problems of existing vehicle safety technologies.
[0004] The technical solution of the present invention to achieve the above objectives is as follows: a motor vehicle intelligent deceleration and avoidance device, including a frame, wherein the frame is provided with an anti-collision structure, a moving structure and an avoidance structure; The anti-collision structure includes: a front anti-collision beam, a rear anti-collision beam, and a monitoring component; The front anti-collision beam is installed on the front side of the vehicle frame, the rear anti-collision beam is installed on the rear side of the vehicle frame, and the monitoring component is installed on the top of the anti-collision structure.
[0005] Preferably, the monitoring components include: a front millimeter-wave radar and a rear millimeter-wave radar; The front millimeter-wave radar is installed at the center of the top of the front bumper beam, and the rear millimeter-wave radar is installed at the center of the top of the rear bumper beam.
[0006] Preferably, the moving structure includes: a front drive shaft, two front moving wheels, a rear drive shaft, and two rear moving wheels; The front drive shaft is mounted on the front side of the bottom end of the frame, and the two front movable wheels are respectively mounted on both ends of the front movable shaft. The rear drive shaft is respectively mounted on the rear side of the bottom end of the frame, and the two rear movable wheels are respectively mounted on both ends of the rear drive shaft.
[0007] Preferably, the safety structure includes: a support plate, a first hydraulic telescopic rod, a connecting rod, two delay blocks, and an emergency deceleration assembly; The support plate is installed at the center of the vehicle frame. The first hydraulic telescopic rod is installed through the front of the top of the support plate. The connecting rod is horizontally connected to the drive end of the first hydraulic telescopic rod. The two delay blocks are respectively installed at both ends of the connecting rod. The emergency deceleration assembly is installed at the rear of the top of the support plate.
[0008] Preferably, the emergency deceleration assembly includes: a second hydraulic telescopic rod, a deceleration brake block, a first support arm, a second support arm, a first bearing seat, and a second bearing seat; The second hydraulic telescopic rod is installed on the rear side of the top of the support plate, the deceleration brake block is installed on the drive end of the second hydraulic telescopic rod, the first support arm is installed on the left side of the side wall of the deceleration brake block, the second support arm is installed on the right side of the side wall of the deceleration brake block, the first bearing seat is movably fitted on the left side of the rear drive shaft and connected to the first support arm, and the second bearing seat is movably fitted on the right side of the rear drive shaft and connected to the second support arm.
[0009] Preferably, the delay block is made of high-density wear-resistant rubber.
[0010] Preferably, the rear end face of the delay block is machined with an arc surface that mates with the front moving wheel.
[0011] Preferably, the width of the deceleration and braking block is greater than the width of the vehicle frame.
[0012] Preferably, the deceleration and braking block can be a metal block or a non-metal block.
[0013] Preferably, the front side of the deceleration and braking block is machined with an arc-shaped chamfer.
[0014] This invention discloses an intelligent deceleration and avoidance device for motor vehicles. By integrating front and rear millimeter-wave radars on the front and rear anti-collision beams respectively, it achieves comprehensive, high-precision, and real-time monitoring of risks in front of and behind the vehicle. This provides accurate information input for subsequent automatic emergency measures, upgrading the device from passively bearing risks to actively responding. The front and rear anti-collision beams form a basic physical protection layer. When a high risk is detected, the vehicle's braking system can be linked to perform intelligent deceleration. When a collision is unavoidable, the first and second hydraulic telescopic rods drive the delay block or deceleration braking block to descend. Utilizing the huge friction between the block and the ground, it achieves forced deceleration beyond conventional braking. This is the core active avoidance method. The deceleration braking block is connected to the rear drive shaft through the first and second support arms and the first and second bearing seats, which can effectively transmit the impact force generated during braking to the frame, avoiding structural damage. At the same time, the drive shaft can constrain its movement trajectory. Furthermore, the size of the two delay blocks is larger than the radius of the two front moving wheels of the vehicle, increasing the contact area for braking the front moving wheels, generating greater frictional resistance, and quickly stopping the vehicle.

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-4 As shown, a vehicle intelligent deceleration and safety avoidance device is described.
[0022] Those skilled in the art should connect all electrical components in this case to their compatible power supplies via wires. Appropriate controllers should be selected based on the actual situation to meet control requirements. The specific connections and control sequence should refer to the working principle described below, which outlines the sequential operation of each electrical component. The detailed connection methods are well-known in the art. The following primarily describes the working principle and process, without further explanation of electrical control. (Those skilled in the art should connect the components in this case sequentially. The specific connections and operating sequence should refer to the working principle described below. The detailed connection methods are well-known in the art. The following primarily describes the working principle and process.) Example: A motor vehicle intelligent deceleration and avoidance device includes a frame 1, characterized in that the frame 1 is provided with an anti-collision structure, a moving structure and an avoidance structure; the anti-collision structure includes: a front anti-collision beam 2, a rear anti-collision beam 3 and a monitoring component; the front anti-collision beam 2 is installed on the front side of the frame 1, the rear anti-collision beam 3 is installed on the rear side of the frame 1, and the monitoring component is installed on the top of the anti-collision structure.
[0023] It should be noted that the frame 1, as the core supporting structure of this device, bears the load and supports the assembly and coordination of various components. Through the front anti-collision beam 2 and the rear anti-collision beam 3, the frame 1 is reinforced as a whole, increasing driving safety, providing collision energy absorption in the event of an accident, preventing severe deformation of the vehicle body from causing injury to the occupants, and providing personnel safety. Through the monitoring components, accidents can be monitored and warned in advance, and intervention operations can be performed. That is, in an emergency, the judgment is made in advance, and the judgment and prediction are converted into signals and transmitted to the driver, so that the driver can take braking operations to slow down the vehicle and avoid dangerous situations.
[0024] Specifically, the monitoring components include: a front millimeter-wave radar 4 and a rear millimeter-wave radar 5; the front millimeter-wave radar 4 is installed at the top center of the front bumper beam 2, and the rear millimeter-wave radar 5 is installed at the top center of the rear bumper beam 3.
[0025] It should be noted that the front millimeter-wave radar 4 and the rear millimeter-wave radar 5 can monitor the vehicle's surrounding environment in real time while driving. When the distance between the vehicle and the vehicle in front is detected to be lower than the safe following distance, an electrical signal is generated and transmitted to the dashboard in the driver's cab to remind the driver to maintain a safe following distance. When the distance between the vehicle behind and the vehicle is lower than the safe distance, an electrical signal is generated again and transmitted to the dashboard in the driver's cab to remind the driver to increase the speed appropriately or take appropriate lane change operations to avoid rear-end collisions caused by vehicles accelerating behind. This early warning and action at the source effectively prevents sudden accidents.
[0026] Specifically, the moving structure includes: a front drive shaft 6, two front moving wheels 7, a rear drive shaft 8, and two rear moving wheels 9; the front drive shaft 6 is mounted on the front side of the bottom end of the frame 1, the two front moving wheels 7 are respectively mounted on both ends of the front moving shaft, the rear drive shaft 8 is respectively mounted on the rear side of the bottom end of the frame 1, and the two rear moving wheels 9 are respectively mounted on both ends of the rear drive shaft 8.
[0027] It should be noted that the frame 1 drives the front drive shaft 6 and the rear drive shaft 8 through the vehicle's power system. The front drive shaft 6 and the rear drive shaft 8 transmit power to the front moving wheel 7 and the rear moving wheel 9, causing the front moving wheel 7 and the rear moving wheel 9 to rotate, thereby driving the frame 1 forward or backward. Through the vehicle's own braking system, it can cooperate with the front and rear moving wheels 9. When the driver presses the brake pedal, the front and rear moving wheels 9 can be decelerated and braked by the braking system, so that the vehicle itself brakes and slows down, achieving a stopping effect. If the vehicle itself is in a dangerous emergency braking situation, when the driver presses the brake pedal urgently, the vehicle control system can switch the oil circuit in the brake pump, quickly connect the brake pump with the avoidance structure, drive the avoidance structure, and decelerate and brake the vehicle. This can increase the braking effect of the vehicle by two to ten times on the original wheel braking effect, so that the vehicle can stop quickly and avoid dangerous emergencies.
[0028] Specifically, the safety structure includes: a support plate 10, a first hydraulic telescopic rod 11, a connecting rod 12, two delay blocks 13, and an emergency deceleration assembly; the support plate 10 is installed at the center inside the frame 1, the first hydraulic telescopic rod 11 is installed through the front of the top of the support plate 10, the connecting rod 12 is horizontally connected to the drive end of the first hydraulic telescopic rod 11, the two delay blocks 13 are respectively installed at both ends of the connecting rod 12, and the emergency deceleration assembly is installed at the rear of the top of the support plate 10.
[0029] It should be noted that the support plate 10 is installed on the frame 1 to support the first hydraulic telescopic rod 11. A connecting rod 12 is suspended at the bottom of the first hydraulic telescopic rod 11, and delay blocks 13 are installed at both ends of the connecting rod 12. The delay blocks 13 correspond to the positions of the front moving wheels 7 and are located in front of the front moving wheels 7. When the vehicle speed is too high, the front millimeter-wave radar 4 detects the road conditions ahead. If the distance between vehicles is too close and falls below the safe driving distance, the driver is reminded to brake and slow down. If a sudden situation occurs at high speed and the driver has to press the brake pedal urgently for emergency braking, the vehicle's built-in system will quickly intervene, causing the brake pump and the first hydraulic telescopic rod to engage. When lever 11 is engaged, the driver presses the brake pedal, and the conventional braking system brakes and decelerates the wheels, driving the first hydraulic telescopic lever 11 to work, which in turn drives the connecting lever 12 to extend and retract downwards. Delay blocks 13 are respectively installed at both ends of the connecting lever 12. The delay blocks 13 first contact the ground, and then contact the front moving wheel 7. When in contact with the ground, the friction area between the vehicle and the ground is increased, thus increasing the braking effect. When rubbing against the front moving wheel 7, the movement of the front moving wheel 7 is interfered with, thus restricting the movement of the front moving wheel 7, thereby reducing the power of the front moving wheel 7, thereby enhancing the deceleration and braking effect of the vehicle, achieving deceleration and braking, and avoiding dangerous consequences caused by sudden situations.
[0030] Specifically, the emergency deceleration assembly includes: a second hydraulic telescopic rod 14, a deceleration and braking block 15, a first support arm 16, a second support arm 17, a first bearing seat 18, and a second bearing seat 19; the second hydraulic telescopic rod 14 is installed on the rear side of the top of the support plate 10, the deceleration and braking block 15 is installed on the drive end of the second hydraulic telescopic rod 14, the first support arm 16 is installed on the left side of the side wall of the deceleration and braking block 15, the second support arm 17 is installed on the right side of the side wall of the deceleration and braking block 15, the first bearing seat 18 is movably fitted on the left side of the rear drive shaft 8 and connected to the first support arm 16, and the second bearing seat 19 is movably fitted on the right side of the rear drive shaft 8 and connected to the second support arm 17.
[0031] It should be noted that during emergency braking in high-speed driving, the delay block 13 participates in braking. However, in situations such as high vehicle weight inertia or emergency braking in rainy or snowy weather, the braking effect of the delay block 13 will decrease accordingly. The vehicle system continues to monitor the situation. If, under the braking deceleration of the delay block 13 and the braking system, the vehicle does not decelerate as expected, the vehicle system connects the brake pump to the second hydraulic telescopic rod 14, driving the second hydraulic telescopic rod 14 to extend and retract downwards. The deceleration and braking block is suspended at the bottom of the second hydraulic telescopic rod 14 and connected via the first support arm 16 and the second support arm 17, as well as the first bearing seat 18 and... Under the support of the second bearing housing 19, the rear drive shaft 8 is connected to the deceleration brake block 15 for hoisting and fixing. At this time, the second hydraulic telescopic rod 14 drives the deceleration brake block 15 to press quickly against the ground, so that the deceleration brake block 15 rubs against the ground in the shortest time and contacts the rear moving wheel 9 to generate friction interference, interfering with the movement of the rear moving wheel 9. In conjunction with the delay block 13 and the braking system, the vehicle continues to obtain contact area with the ground, thereby increasing the contact area to obtain friction and thus increasing the braking effect tenfold. This reduces the vehicle's inertia and increases the braking force, quickly reducing the vehicle's speed from driving to zero, and finally bringing the vehicle to a smooth stop.
[0032] Specifically, the delay block 13 is made of high-density wear-resistant rubber material, and the size of the delay block 13 is larger than the radius of the front moving wheel 7. This can increase the friction with the ground during braking and interfere with the movement of the front moving wheel 7, achieving twice the braking effect of the vehicle's own braking system.
[0033] Specifically, the rear end face of the delay block 13 is machined with an arc surface that mates with the front moving wheel 7. During emergency braking, the delay block 13 can not only contact the ground to generate frictional resistance for deceleration, but also interfere with the movement of the front moving wheel 7, restricting its movement and preventing it from locking up and slipping. In addition, it increases the frictional area of the moving wheel, increasing frictional resistance, and ultimately decelerating and stopping the vehicle.
[0034] Specifically, the width of the deceleration and braking block 15 is greater than that of the frame 1, increasing the area for friction with the ground to achieve a braking effect ten times greater than that of the delay block 13 and the braking system itself, thus achieving braking and deceleration.
[0035] Specifically, the deceleration and braking block 15 can be a metal block or a non-metal block, which can reduce damage to the road surface and adapt to different application scenarios.
[0036] Specifically, the front side of the deceleration brake block 15 is machined with an arc-shaped chamfer to prevent the brake block from being damaged by irregular ground surfaces or by a sudden huge impact force when braking and rubbing against the ground.
[0037] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
