Problems solved by technology

[0004] However, the pedestrian protection device described in JP-11-28994A does not take into account the different front heights of various vehicles and the different heights of pedestrians
When a short pedestrian (such as a child) collides with a tall vehicle such as an SUV vehicle, the pedestrian cannot be guided to roll over on the front hood, thereby failing to protect the pedestrian

Embodiment Construction

[0015] The preferred embodiment will be described with reference to the drawings.

[0016] (Preferred embodiment)

[0017] Will refer to Figure 1-3 To describe the preferred embodiment of the present invention.

[0018] The pedestrian protection device is provided with a collision sensor 1, an electronic control unit 2, a lifting unit 3, an airbag 4 and a plurality of height adjustment units 5, such as figure 1 Shown in. Such a pedestrian protection device is generally used in the station wagon (vehicle 100) in this embodiment. The engine compartment 400 is positioned at the front of the vehicle 100, and the engine hood 500 is arranged above the engine compartment 400 so as to cover the engine compartment 400. figure 1 The front-rear direction shown in corresponds to the longitudinal direction of the vehicle 100.

[0019] The collision sensor 1 is provided on the vehicle bumper 200 at the front surface of the engine compartment 400 for detecting any collision and outputting a de...

Abstract

A pedestrian protecting device has a collision sensor (1), an electronic control unit (2), an elevator unit (3), an airbag (4), and a height adjustment units (5). The collision sensor (1) is provided in the front of the vehicle (100) for detecting the collision. When the electronic control unit (2) determines that the vehicle (100) collides together with a pedestrian, the electronic control unit (2) drives and lifts the elevator unit (3), the airbag (4), and the height adjustment units (5). Thus, when the elevator unit (3) lifts a bonnet (500) of the vehicle (100), The height adjustment unit (5) lowers the vehicle (100), which leads the pedestrian to the bonnet (500) to be protected by the airbag (4).

Description

Technical field [0001] The invention relates to a pedestrian protection device, which is used to reduce the damage to pedestrians in a collision with a vehicle. Background technique [0002] In a traffic accident, not only the passengers in the vehicle, but also people (such as pedestrians) colliding with the vehicle must be protected to prevent fatal injuries. Preferably, the pedestrian protection device reduces damage to pedestrians caused by collision with a vehicle (for example, the front hood of the vehicle), regardless of whether the pedestrian is an adult or a child. [0003] When a pedestrian collides with a moving vehicle and jumps up, the pedestrian will collide with the front engine hood of the vehicle again (secondary collision). The pedestrian protection device is connected to the vehicle so that the front hood rises upward to absorb and buffer the secondary collision, thereby reducing the damage to the pedestrian (for example, JP-11-28994A). [0004] However, the pe...
