Embodiment 1
[0033] refer to figure 1 As shown, the first embodiment of the present invention provides a pedestrian safety protection device for a vehicle, including: a pedestrian protection plate 1 and an elastic expansion member 3 .
[0034] Wherein, the pedestrian protection plate 1 is fixed to the vehicle body 2 and has a first state of being attached to the vehicle body 2 and a second state of being lifted on the vehicle body 2 . The elastic expansion part 3 is arranged between the pedestrian protection plate 1 and the vehicle body 2, and drives the pedestrian protection plate 1 to move relative to the vehicle body 2 when the elastic expansion part 3 is energized. During use, the movement of the pedestrian protection plate 1 is controlled by the elastic expansion member 3. During normal driving, the pedestrian protection plate 1 is attached to the vehicle body 2; Relative to the vehicle body 2, it is lifted upwards, which is convenient and timely, and provides a buffer space for the ...

The invention provides a pedestrian safety protection device for an automobile. The pedestrian safety protection device is characterized by comprising a pedestrian protection board and elastic expansion parts, wherein the pedestrian protection board is fixed to an automobile body and has a first state of being attached to the automobile body and a second state of being lifted from the automobile body; the elastic expansion parts are arranged between the pedestrian protection board and the automobile body; and the elastic expansion parts drive the pedestrian protection board to move relative tothe automobile body when electrified. The invention also provides the automobile which comprises the pedestrian safety protection device for the automobile. The pedestrian safety protection device for the automobile is simple in structure, low in cost and easy to be additionally mounted on the existing automobile. The temperature sensing and driving properties of memory alloy springs can be utilized to control the movement of the pedestrian protection board, and the response is fast. Through the on-off control of connection currents, intelligent adjustment under different temperature responses is realized, and the pedestrian safety is protected.
Description
technical field [0001] The invention relates to the technical field of automobile safety, in particular to a pedestrian safety protection device for a vehicle and an automobile. Background technique [0002] The pedestrian protection system is a passive safety subsystem of the vehicle. When a car hits a pedestrian, the pedestrian protection system can be used to reduce the impact acceleration between the head of the pedestrian and the hood of the car. It is a new type of driving safety subsystem. [0003] The current pedestrian protection system is mainly based on lifting the hood, and the height of the hood is raised by about 10 cm to give pedestrians a buffer space for their heads. However, the cost of the lifting mechanism and its detonating device is high and the structure is relatively complicated. It is inconvenient to install on the existing car, and it takes a certain time for the lifting mechanism to lift. It is likely that a collision accident will occur before the...
