Abstract
The utility model provides a pedestrian protecting device of an automobile, which is capable of reducing harm to legs of pedestrians. The pedestrian protecting device comprises a front protection beam mounted at the front end of a front longitudinal beam, a buffer foam block mounted at the front end of the front protection beam, and an additional beam disposed below the front protection beam, wherein the buffer foam block projects farther forwardly than the additional beam. In collision between an automobile and a pedestrian, legs of the pedestrian firstly contact with the buffer foam block of the front protection beam, the buffer foam block deforms to absorb the collision energy so as to reduce harm to the legs of the pedestrian, then the legs of the pedestrian contact with the lower additional beam which topples the pedestrian toward the automobile, and thereby the legs of the pedestrian can leave the automobile so as to be protected. The pedestrian protecting device is simple in structure and low in cost, can be conveniently mounted on the automobile without substantially changing a front compartment structure of an original automobile body, effectively reduces harm to the legs of the pedestrians in collisions, and increases safety grade of the automobile.
Description
Technical field
The utility model belongs to field of automobile, specially refers to the device that is used to protect the pedestrian on the automobile.
Background technology
Along with the development of automotive technology and the raising of people's awareness of safety, the protection of automobile no longer is confined to protect the passenger in the car, but expands the pedestrian who bumps with automobile to.When automobile and pedestrian bump, all be usually vehicle body directly and pedestrian's calf come in contact, pedestrian's calf is damaged.Though have a lot of vehicles to reduce the possibility that bumps at present, can not stop automobile injury to pedestrian's calf when collision by increasing active safety feature.
The utility model content
The purpose of this utility model is to propose a kind of pedestrian protection that can reduce the automobile of pedestrian's calf injury.
The pedestrian protection of automobile of the present utility model comprises the preceding guarantor's crossbeam that is installed in the front side member front end; key is that the described preceding front end of protecting crossbeam is equipped with the buffering foam block; the below of protecting crossbeam before described is provided with additional crossbeam, described buffering foam block than described additional crossbeam prominent before.
Because the buffering foam block than described additional crossbeam prominent before, therefore in automobile and pedestrian's collision process, protect the buffering foam block of crossbeam before pedestrian's shank at first touches, deformation can take place to absorb collision energy in the buffering foam block, reduces the injury to pedestrian's calf; Pedestrian's calf touches the additional crossbeam of below more then; the position of additional crossbeam can apply a power forward to the pedestrian on the lower side, and the pedestrian is toppled over to automobile steering; pedestrian's calf will disengage with automobile like this, thereby has protected pedestrian's calf.
For conveniently installing and guaranteeing firm; described additional crossbeam preferably is installed on the water tank cross sill of automobile; the intensity of water tank cross sill is higher; can support the weight of additional crossbeam; and be difficult for when colliding taking place deformation with the people; thereby can guarantee the pedestrian is toppled over to automobile steering protection pedestrains safety.
The terrain clearance of described additional crossbeam is not higher than 30 centimetres, and the too high impulsive force that can strengthen pedestrian's calf below of the terrain clearance of additional crossbeam causes certain injury to the pedestrian.
The terrain clearance of described buffering foam block is between 30 centimetres～50 centimetres, and according to statistics, 30 centimetres～50 centimetres these sections highly interval are the height of general pedestrian's knee, highly the buffering foam block are set the interval at this, can protect pedestrian's knee better.
Pedestrian protection of the present utility model is simple in structure, cost is low, can be installed in easily on the automobile under the prerequisite of not changing cabin structure before original vehicle body substantially, to the injury of pedestrian's calf, improves the automotive safety grade when reducing collision effectively.
Description of drawings
Fig. 1 is the structural representation of the additional crossbeam in the pedestrian protection of automobile of present embodiment;
Fig. 2 is the structural representation of the buffering foam block in the pedestrian protection of automobile of present embodiment;
Fig. 3 is the integral structure scheme drawing of pedestrian protection of the automobile of present embodiment.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in the figure; the pedestrian protection of the automobile of present embodiment comprises and is installed in left front longeron 5; preceding guarantor's crossbeam 7 of right front longeron 4 front ends; the preceding front end of protecting crossbeam 7 is fixed with buffering foam block 3 with stickup glue; the preceding below of protecting crossbeam is provided with additional crossbeam 1; the main body of described additional crossbeam 1 is the groove shape; can reduce under the prerequisite of weight; strengthen its rigidity; additional crossbeam 1 is provided with mounting bracket 2; additional crossbeam 1 is installed on the water tank cross sill 6 of automobile by mounting bracket 2; before buffering foam block 3 was dashed forward than additional crossbeam 1, wherein the terrain clearance of additional crossbeam 1 was about 18 centimetres, and the terrain clearance of buffering foam block 3 is about 40 centimetres.
Because buffering foam block 3 than additional crossbeam 1 prominent before, therefore in automobile and pedestrian's collision process, pedestrian's shank at first touches buffering foam block 3, buffering foam block 3 can the generation deformation with the absorption collision energy, reduction is to the injury of pedestrian's calf; Pedestrian's calf touches the additional crossbeam 1 of below more then; the position of additional crossbeam 1 can apply a power forward to the pedestrian on the lower side, and the pedestrian is toppled over to automobile steering; pedestrian's calf will disengage with automobile like this, thereby has protected pedestrian's calf.
Claims (4)
1. the pedestrian protection of an automobile; comprise the preceding guarantor's crossbeam that is installed in the front side member front end; it is characterized in that the front end of protecting crossbeam before described is equipped with the buffering foam block, the below of protecting crossbeam before described is provided with additional crossbeam, described buffering foam block than described additional crossbeam prominent before.
2. the pedestrian protection of automobile according to claim 1 is characterized in that described additional crossbeam is installed on the water tank cross sill of automobile.
3. the pedestrian protection of automobile according to claim 1 and 2 is characterized in that the terrain clearance of described additional crossbeam is not higher than 30 centimetres.
4. the pedestrian protection of automobile according to claim 1 and 2, the terrain clearance that it is characterized in that described buffering foam block is between 30 centimetres～50 centimetres.
