Example Embodiment
[0030] Example 1: see figure 1 — Picture 9 , Picture 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 rod or rope (wire rope or chain) at the front end of the support rod. At least one rotating shaft is arranged in the middle of the device to form a soft connection structure. In the present invention, the angle range between the pull rod or the pull rope and the support rod after being straightened is between 45 degrees and 120 degrees. This angle range can ensure that the pull rod or the pull rope first directly contacts the cart to generate a pulling force in the event of a collision. The best pulling effect can be achieved when the range of the included angle is close to 90 degrees, so the included angle in the range of 60 degrees to 90 degrees is preferred. The lower end of the pull rod or the pull rope is hinged to the front end of the car b...
Example Embodiment
[0036] Example 2: see figure 1 , image 3 — Image 6 , Picture 12 with Figure 13 , A rear-end collision prevention device for a car. Support rods 3 are hidden on both sides of the hood 8 respectively. The support rods 3 and the hood 8 have basically the same direction on both sides to facilitate concealment and compromise. In this embodiment, the support rod 3 is fixed under the engine. The rear end of the support rod 3 is located near the hinge of the hood 8 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, the middle of the upper and lower sections are connected together by a rotating shaft 40, so that the pull rod becomes foldable. The lower ends of the pull rods on both sides are hinged to the front end of the car frame 1. Thus, the car frame, the support rod, and the distance between the car frame and the support rod form a tr...
Example Embodiment
[0038] Example three: see figure 1 , Figure 7 — Picture 9 , Picture 12 with Figure 13 , The content is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that the pull rod is replaced with a pull rope (wire rope or chain).
