Embodiment 1

[0017] Embodiment 1: as figure 1 As shown, a front cover hinge that can realize pedestrian protection includes a fixed arm 1 and a movable arm 2. The free end of the movable arm is hinged with an energy storage arm 3. The energy storage arm is located on the side of the fixed arm. Slot 31, the side of the fixed arm is provided with a guide block 5 matched with the chute, the energy storage spring 4 is connected between the bottom of the energy storage arm and the guide block, the side edge of the energy storage arm is provided with locking teeth, and the side of the fixed arm is hinged There is a locking arm 6 controlled by a signal, and the free end of the locking arm is provided with a pin matched with the bayonet. Such as Figure 5 As shown, the locking tooth includes a laterally disposed locking surface 71 and an obliquely upwardly inclined guiding surface 72 , and the pin includes an insertion surface 81 that cooperates with the locking surface and a mating surface 82 th...

Embodiment 2

[0019] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Image 6 As shown, the inner edges of both sides of the middle section of the chute protrude inwardly to be provided with a buffer transition part 9, the buffer transition part is arc-shaped, and a second-stage energy storage spring 10 is connected between the top of the energy storage arm and the guide block. The elastic force of the energy spring is smaller than that of the energy storage spring; the second-stage energy storage spring is in a natural state when the guide block is located at the buffer transition part.

[0020] The inner edges of both sides of the middle position of the chute protrude inward to set a buffer transition part. The upper part is arc-shaped, nearly as a buffer transition, and will not excessively hinder the passage of the guide block. A second-order energy storage spring is arranged between the top of the energy storage ...

Abstract

The invention relates to automobile front covers, in particular to a front cover hinge capable of achieving pedestrian protection. The front cover hinge capable of achieving pedestrian protection comprises a fixed arm and a movable arm. An energy storage arm is hinged to the free end of the movable arm. The energy storage arm is located on the side face of the fixed arm and is provided with a sliding chute. A guide block matched with the sliding chute is arranged on the side face of the fixed arm. An energy storage spring is connected between the bottom of the energy storage arm and the guide block. A latch is arranged on the side edge of the energy storage arm. A locking arm controlled through signals is hinged to the side face of the fixed arm. An insertion pin matched with the latch is arranged at the free end of the locking arm. The front cover hinge has the beneficial effects that recycling can be realized, energy absorption can be effectively achieved during collision, the energy absorption effect is enhanced, and pedestrians can be protected.

Description

technical field [0001] The invention relates to an automobile front cover, in particular to a front cover hinge capable of realizing pedestrian protection. Background technique [0002] In my country's road traffic accidents, the probability of collision accidents between pedestrians and vehicles is high, accounting for about 20% of the total number of traffic accidents; due to the current situation of mixed traffic in my country, the probability of collision accidents between two-wheelers and vehicles is high, accounting for about 20% of the total number of traffic accidents Half; among the number of casualties in road traffic accidents in my country, the number of pedestrian deaths accounts for about 30%. In developed countries and regions such as Europe, Japan, and South Korea, pedestrian protection has become a mandatory standard and regulation. In order to effectively protect pedestrians, the common and most effective way is to increase the collision buffer space to abs...
