Embodiment 1

[0030] Embodiment one: see figure 1 — Figure 9 , Figure 12 with Figure 13 , a method for preventing rear-end collision of a car, the method is to hinge a support rod on the front window frame column (A-pillar) in the hood, and hinge a pull rod or a pull rope (wire rope or chain) at the front end of the support rod, the pull rod At least one rotating shaft is arranged in the middle part to form a flexible connection structure. In the present invention, the angle range between the pull rod or the pull rope and the support rod after straightening is between 45° and 120°, which can ensure that the pull rod or pull rope first directly contacts the cart to generate pulling force when it collides. The best pulling effect can be achieved when the range of the included angle is close to 90 degrees, so an included angle in the range of 60 degrees to 90 degrees is preferred. The lower end of said pull rod or stay rope is hinged on the front end of the car frame.

Embodiment 2

[0036] Embodiment two: see figure 1 , image 3 — Image 6 , Figure 12 with Figure 13 , a car anti-rear-collision device, the two sides in the engine cover 8 are respectively hidden with a support rod 3, the support rod 3 and the direction of the engine cover 8 both sides are basically consistent to facilitate hiding and giving way. In the present embodiment, the support rod 3 is fixed below the engine, and the rear end of the support rod 3 is located near the engine cover 8 hinges, and can be welded together with the upper page of the hinge. The front end of the support rod 3 is hinged with a pull rod, and the pull rod includes The upper section 41 and the lower section 42, and the middle parts of the upper and lower sections are connected together by a rotating shaft 40, so that the pull bar becomes foldable. The lower ends of the pull rods on both sides are hinged on the front end of the car frame 1. Thereby, the vehicle frame, the supporting rod, and the distance bet...

Embodiment 3

[0038] Embodiment three: see figure 1 , Figure 7 — Figure 9 , Figure 12 with Figure 13 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the pull rod is changed into a stay rope (wire rope or chain).

Abstract

The invention discloses a car rear-end collision prevention method and a car rear-end collision prevention device. The car rear-end collision prevention method is characterized in that supporting rods are arranged on two sides of an engine hood in a hidden manner, a car girder can be used as supporting points of the rear ends of the supporting rods, the front ends of the supporting rods are hinged with pull rods or pulling ropes, at least one connection pin is arranged in the middle of each pull rod so that two sections of each pull rod are in flexible connection during pulling the pull rods, the lower ends of the pull rods or the pull ropes are hinged with the front end of the car girder, when in a rear-end collision accident, speed and distance can be measured by radars or infrared sensing elements, at the critical instant of crashing inevitably, the rear-end collision prevention device is actuated to be supports, the supporting rods and the car girder form a triangular stabilizing structure, inward pulling force can be generated by the pull rods or pull ropes, the supporting rods of the car can be clamped at the rear of a truck, and accordingly, the car and passengers can be protected well and the accident that the car is crashed into the rear end of the truck is prevented. Besides, the car rear-end collision prevention device is simple in structure, easy to be modified or manufactured, low in production cost, fine in service effect, quite favorable for popularization and realizing and capable of preventing traffic accidents.

Description

technical field [0001] The invention relates to a car safety protection device, in particular to an anti-rear collision device for preventing a car from getting into the rear bottom of a large truck. Background technique [0002] Usually, the chassis of a large truck is high and the body of a car is exposed to the bottom. In this case, once a rear-end collision accident occurs with a car behind, it will cause quite serious consequences. The chamber is deformed or even shoveled off. Such traffic accidents are not uncommon. At present, the collision test for the safety performance inspection of cars before leaving the factory is limited to the direct collision detection of plane obstacles and the detection of side impacts. A situation where the car is destroyed but the people are safe. The safety inspection of the car leaving the factory is to ensure that no matter how serious the car damage is after hitting a plane obstacle, the safety of the cab personnel is enough, an...
