Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile deceleration and emergency avoidance, and particularly relates to an emergency deceleration and emergency avoidance device. BACKGROUND

[0002] When a motor vehicle is running at high speed or a large vehicle is running downhill at a large slope, the speed is very fast and the inertia is very strong, which often causes brake failure. The Engineering Training Center of Beihua University once investigated the causes of truck traffic accidents and concluded that 75.3% of the causes of truck traffic accidents were that the braking distance was too long, and the brake was the primary cause of major accidents. In the case of abnormal braking noise or sudden decrease in braking force, a common braking method is to use the hand brake to pull it to the bottom or pull it too fast, which requires a certain degree of proficiency of the driver. In this case, if a device can transfer the speed energy of the driving wheel to reduce the speed of the vehicle and stop it in a short time, it can timely avoid a vehicle damage and human death accident. Therefore, the present application provides an emergency deceleration and emergency avoidance device to solve the above problems. SUMMARY

[0003] In view of the problems existing in the prior art, the present application provides an emergency deceleration and emergency avoidance device. The present application provides an emergency avoidance structure to replace the emergency braking mode of the hand brake. When emergency braking, the arc-shaped plate located in front of the driving wheel falls, the bottom surface slides and frictionally decelerates, and the top surface rolls and frictionally decelerates the wheel, thereby achieving emergency braking of the vehicle with minimal damage to the wheel. At the same time, during the braking process, due to the dragging frictional movement formed by the arc-shaped plate and the bottom surface, when the power of the vehicle is small, the braking device of the driven wheel forces the vehicle to stop urgently.

[0004] In order to achieve the above purpose, the emergency deceleration and emergency avoidance device adopted by the present application comprises:

[0005] The arc-shaped plate can fall. The arc-shaped plate is arranged above the front of the driving wheel and at the position of the bottom plate of the vehicle compartment. The bottom surface of the arc-shaped plate is an arc-shaped surface in contact with the ground and generating sliding friction, and the top surface of the arc-shaped plate is a rolling surface in contact with the wheel and generating rolling friction. At least two stop wheels are rotatably connected to the rolling surface.

[0006] The above structure, when emergency braking, the arc-shaped plate located in front of the driving wheel falls, the bottom surface slides and frictionally decelerates, and the top surface rolls and frictionally decelerates the wheel, thereby achieving emergency braking of the vehicle with minimal damage to the wheel. At the same time, during the braking process, due to the dragging frictional movement formed by the arc-shaped plate and the bottom surface, when the power of the vehicle is small, the braking device of the driven wheel forces the vehicle to stop urgently.

[0007] As a further optimization of the above scheme, the center of the arc-shaped plate is embedded with a power coil, and the stop wheel is installed with a magnet, and the power coil generates an electromagnetic force to drive the stop wheel to rotate towards the wheel, the electromagnetic force generated by the power coil drives the stop wheel to swing and the swing direction is opposite to the wheel turning, and the arc-shaped plate side is provided with a through hole for the side movement of the stop wheel. The power coil and the stop wheel constitute a structure similar to magnetic suspension. By energizing the power coil, an electromagnetic force is generated to drive the stop wheel to have an outward force to drive the stop wheel to closely contact the wheel. At the same time, the electromagnetic force can also drive the stop wheel to swing in the opposite direction of the wheel turning to further enhance the effect of the stop wheel braking the wheel.

[0008] As a further optimization of the above scheme, the arc-shaped plate has a gap with the stop wheel, preferably, the gap is 5mm, to ensure that when the wheel contacts the stop wheel, the stop wheel does not contact the arc-shaped plate.

[0009] As a further optimization of the above scheme, the side of the stop wheel is connected with a pressing block, a groove is arranged on the side of the through hole, the pressing block partially enters the groove, and a first air bag part for buffering the pressing block is arranged on the circumferential path of the pressing block, the bottom surface of the arc-shaped plate is provided with a second air bag for buffering, the second air bag is connected with the first air bag through an air guide pipe, the first air bag part is spherical and partially passes through the groove, the side of the through hole is arc-shaped and the diameter decreases from bottom to top, and the groove is arranged on the upper part of the side of the through hole. The communication between the first air bag and the second air bag forms a bidirectional buffering structure. The first air bag buffers the swing effect of the pressing block, avoids excessive rotation of the stop wheel, and improves the braking effect of the stop wheel. At the same time, the first air bag is inflated during the pressing process, the contact area of the second air bag with the ground is increased, and the sliding friction effect of the arc-shaped plate with the bottom surface is improved.

[0010] The emergency use speed reduction safety device has the following beneficial effects:

[0011] 1. The emergency use speed reduction safety device has a double-sided braking structure. When the emergency brake is applied, the arc-shaped plate in front of the driving wheel falls, the bottom surface slides and frictionally reduces the speed, and the top surface rolls and frictionally reduces the speed of the wheel, so that the emergency brake of the vehicle is realized with the least damage to the wheel. At the same time, during the braking process, due to the drag friction motion formed by the arc-shaped plate and the bottom surface, when the power of the vehicle is small, the braking device of the driven wheel forces the vehicle to stop urgently.

[0012] 2、The emergency use deceleration safety device of the application, aiming at the brake structure of the wheel contact side, selects the magnetic suspension structure composed of the energized coil and the stop wheel, the electromagnetic force generated after the energized coil is energized drives the stop wheel to have an outward force to drive the stop wheel to tightly contact with the wheel, and the electromagnetic force can also drive the stop wheel to swing in the direction opposite to the wheel turning to further enhance the effect of the stop wheel braking the wheel.

[0013] 3、The emergency use deceleration safety device of the application, aiming at the double-sided brake structure, additionally adds the bidirectional buffer structure formed by the communication of the first air bag and the second air bag, the swing effect of the first air bag buffer block is avoided to prevent the stop wheel from excessively rotating and enhance the braking effect of the stop wheel, and in the process of the first air bag being pressed, the second air bag is inflated to enhance the contact area of the second air bag with the ground to enhance the sliding friction effect of the arc plate with the ground.
