The utility model discloses a form on the barrier component of the groove apron of falling into water and weaken the structure, the mechanical strength who weakens the structure is less than all the other parts that barrier component. The mechanical strength of the blocking part is weakened through the weakening structure, when the head of a pedestrian impacts the front cover and the front cover deforms and contacts the blocking part downwards, the blocking part can be collapsed in time to absorb energy, and the injury of the front cover to the head of the pedestrian is reduced. The blocking

members

101 and 102 distributed in different areas on the gutter cover 100 have different structures, and the weakening structures of the blocking members in different areas are different. In the embodiment shown in fig. 2, the barrier member is generally divided into three regions: the blocking component 101 is a herringbone wall, the herringbone wall is distributed along the edge of the front cover and transversely penetrates through the water falling groove cover plate, the middle area of the water falling groove cover plate 100 is an area A, and the edge area of the water falling groove cover plate 100 is an area B. The stop members 102 are bosses located on both sides of the windshield and below the front panel, and in the embodiment shown in fig. 2, the bosses are located on both sides above the gutter cover 100, which is region C.

Fig. 3 discloses a sectional structure view of a herringbone wall area of a sink cover plate in the middle according to an embodiment of the present invention. Fig. 3 shows a cross-sectional structure of the area a in fig. 2. Referring to fig. 3, the gutter cover 100 is disposed in front of the front windshield 201 and extends below the front cover. Above one side of the gutter cover 100 are a front windshield 201, a wiper 202 and a windshield cross-member 203. The other side of the gutter cover 100 extends below the front cover and includes the following around the side: the front wall metal plate 204, the front cover sealing strip 205, the front cover inner plate 206 and the front cover outer plate 207. The barrier member in zone a is a gable 101, the gable 101 being formed by a long wall 111 and a short wall 112 overlapping obliquely, the part below the overlap of the long and short walls forming the root of the triangular gable, and the part above the overlap of the long and short walls forming the tip of the gable extending upwardly. In the area A, namely the weakening structure of the herringbone wall positioned in the middle of the cover plate of the water falling groove is a weakening groove, the thickness of the material at the joint of the long wall and the short wall is reduced, and after the thickness is reduced, the mechanical strength of the area is reduced. In one embodiment, the herringbone wall is made of plastic. Fig. 4 discloses a cross-sectional structure view of a double weakening groove of a sink cover according to an embodiment of the present invention. In the embodiment shown in fig. 4, the weakening structure of the gable in the middle of the downpipe cover plate is a double weakening groove, and the material thickness of the long wall 111 and the short wall 112 at a position close to the overlap is reduced to form two weakening

grooves

113 and 114 with different directions. In one embodiment, the thickness of the weakening groove is 40% -60% of the thickness of the wall. For example, the thickness of the material of the long wall and the short wall may be 1.8mm to 2mm, and the thickness of the weakening groove may be 0.8mm to 1.2 mm. The double weakening grooves are arranged, so that the herringbone wall can adapt to impact in different directions, and energy absorption and crumpling are timely realized. In the process of carrying out a pedestrian protection test, when the herringbone wall area in the middle of the water falling groove cover plate is impacted, the tip of the herringbone wall deforms and transmits the impact to one side of the weakening groove, and the weakening groove begins to be influenced by deformation and impact. The weakening groove structure has the function of reducing the rigidity of the structure and greatly reducing the acting force required for fracture. When the weakening groove is stressed, the weakening groove begins to deform. When the stress is too large, the weakening groove deforms violently, the weakening groove structure is broken, the cover plate of the water falling groove cannot continue to prevent the conduction process of deformation of the front cover, the injury value of the head of a pedestrian cannot continue to increase, and the injury value of the head of the pedestrian may even drop sharply, so that the protection safety of the head of the pedestrian is facilitated. The herringbone wall adopts a double weakening groove structure, the structure of the middle herringbone wall can be weakened from two different directions, and impact can be weakened through fracture in two different directions. Referring to FIG. 4, when the center gable tip is impacted by the front cover, a directional force is generated as shown by F1 and the relief groove 113 is activated. If the front end face of the cover plate of the sink is impacted by the impact transmitted by the front cover, a directional force is generated as shown by F2, and the weakening groove 114 can play a role. The double weakening grooves can play a role in the tip direction of the herringbone wall and the front end face direction of the water falling groove cover plate, and the safety protection of the head of a pedestrian in a larger area is realized. The herringbone wall in the area A adopts a weakening groove structure, so that hard plastics are used in the material.
