Embodiment Construction

[0039] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] figure 1 It is a structural schematic diagram of an embodiment of the protection device for preventing pedestrian's calf from submerging according to the present invention. Such as figure 1 As shown, the present invention provides a protection device for preventing the lower legs of pedestrians from diving, including:

[0041] The collision sensor 101 is used for: detecting whether a collision occurs at the front end of the vehicle, and sending a collision signal when detecting a collision at the front end of the automobile;

[0042] The controller 102 is configured to: issue an instruction to inflate the air bag 105 according to the collision signal;

[0043] The safety airbag 103 includes a gas generator 104 and a first air bag 105, used for: the gas generator 104 inflates the first air bag 105 according to the infla...

Abstract

The invention discloses a protecting device for preventing pedestrian shank diving and a method thereof and relates to the field of automobile safety driving protection. The device comprises a collision sensor, a controller and a safety air bag. The collision sensor is used for giving out a collision signal before the front end of an automobile collides. The controller is used for giving out an air bag inflating instruction according to the collision signal. The safety air bag comprises an air generator, a first air bag and a second air bag. The air generator inflates the first air bag according to the air bag inflating instruction. The first air bag covers a front bumper after being fully inflated. The second air bag covers the longitudinal gap from the front bumper to the ground after being fully inflated. The popping out inflated air bags have the buffer function between the bumper and a pedestrian when the automobile collides with the pedestrian, collision damage of the pedestrian is reduced. In addition, shank of the pedestrian is blocked by the air bags and prevented from diving instantly after front collision, and possibility of rolling-over accidents is reduced greatly.

Description

technical field [0001] The invention relates to the field of automobile safety driving protection, in particular to a protection device and method for preventing pedestrians' calves from submerging. Background technique [0002] In the prior art, there is a certain gap between the front bumper of the automobile and the ground, so as to meet the passing performance of the automobile in a specific environment. This clearance varies from model to model. [0003] However, this gap can allow pedestrians (especially children) to dive under the front bumper in the event of a frontal collision with the car, thereby being crushed. Contents of the invention [0004] The purpose of the present invention is to provide a protection device and method for preventing the pedestrian's calf from submerging, so as to prevent the occurrence of the situation that the pedestrian's calf sneaks into the bottom of the car and is crushed when the pedestrian collides with the car. [0005] In orde...
