  In the front pillar structure, air flow is disturbed by a step between the windshield and the pillar outer cover during traveling of the vehicle, so that air resistance may increase. In the front pillar structure, when the snow attached to the windshield is wiped off with a wiper while the vehicle is snowing, the snow wiped off by the wiper accumulates on the stepped portion between the windshield and the pillar outer cover. As a result, the necessary field of view may not be ensured. Further, in the front pillar portion structure, a step between the windshield and the pillar outer cover may cause the appearance of the vehicle to deteriorate.

  On the other hand, recent vehicles are required to improve the protection performance for pedestrians to reduce damage to pedestrians when a contact accident with pedestrians occurs.

  The object of the present invention is to reduce the air resistance during running of the vehicle, improve the snow drainability during snowfall and improve the appearance of the vehicle, and provide protection performance against pedestrians when in contact with pedestrians. An object of the present invention is to provide a vehicle front pillar structure that can be improved.

In order to achieve the above object, the present invention is located between the windshield provided on the front side of the vehicle body, the front doors provided on both sides in the width direction of the vehicle body, and the windshield and the front door. A front pillar, and a pillar outer cover provided on the outer surface side of the front pillar and formed so that an outer surface of a portion adjacent to the windshield has substantially the same height as the outer surface on the windshield side. A front pillar structure of a vehicle, wherein between the front pillar and the pillar outer cover, a flow passage is provided through which air and rainwater that circulates in front of the windshield by traveling of the vehicle can flow. the flow path, the vehicle width snow to guide the air and rainwater to the flow path provided between the pillar outer cover and the windshield And to that inlet guide to the direction outwardly, at least one of the front pillar and the pillar outer cover, is formed to extend in the longitudinal direction of the front pillar, separating the air and rainwater by contacting the inflowing rain water A rib that has a width smaller than the width of the inlet, and an air outlet through which air separated from the rainwater by the rib flows out to the front door side, and the rainwater separated by the rib is glass of the front door And a rib projecting obliquely between the front pillar and the pillar outer cover with respect to the front-rear direction of the vehicle.

  As a result, rain water that has circulated from both sides in the width direction of the outer surface of the windshield circulates through the flow path while the vehicle is raining, so the outer surface of the pillar outer cover on the windshield side is connected to the windshield pillar. It becomes possible to make it the same height as the outer surface of the part adjacent to the outer cover.

  In addition, when an impact force acts on the pillar outer cover from the front of the vehicle, the impact force acts in the direction in which the ribs are bent, so that a drag force against the impact force does not act on the front of the vehicle.

  According to the present invention, the outer surface of the pillar outer cover on the windshield side can be set to the same height as the outer surface of the portion adjacent to the pillar outer cover of the windshield. In addition to being able to reduce, it is possible to prevent the snow from accumulating on both sides in the width direction of the windshield while the vehicle is snowing and to improve the appearance of the vehicle.

  Further, according to the present invention, since the drag force against the impact force from the front of the vehicle does not act on the front of the vehicle, it is possible to reduce the pedestrian's head injury value at the time of contact with the pedestrian. It becomes possible to improve the protection performance of the vehicle against pedestrians.

The strength is maintained by integrating these members 21, 22, and 23.

  The pillar inner cover 30 is made of, for example, a synthetic resin member, and covers the front pillar 20 from the vehicle interior side.

  The pillar outer cover 40 is made of, for example, a synthetic resin member, and covers the pillar outer panel 23 located between the windshield 3 and the front door 4 from the outside. Further, the pillar outer cover 40 is formed so that the outer surface on the windshield 3 side is substantially the same height as the outer surface of the portion adjacent to the pillar outer cover 40 of the windshield 3. Between the pillar outer cover 40 and the front pillar 20, there is a flow passage 41 between the pillar outer cover 40 and the front pillar 20 between the pillar outer cover 40 and the front pillar 20. A flow passage forming plate 42 is formed along the outer surface of the pillar outer panel 23 of the front pillar 20. Here, the outer surface on the side of the windshield 3 and the outer surface of the portion adjacent to the pillar outer cover 40 of the windshield 3 are formed at substantially the same height only when the height is strictly the same. In addition, for example, a case where there is a difference of about 2 mm to 3 mm is also included.

  The pillar outer cover 40 is provided with at least one rib 40 a that protrudes toward the flow path forming plate 42 and extends along the longitudinal direction of the pillar outer cover 40. The flow passage forming plate 42 is provided with at least one rib 42 a that protrudes toward the pillar outer cover 40 and extends in the longitudinal direction of the flow passage forming plate 42. Thereby, the flow path 41 is formed to meander and extend from the windshield 3 side to the front door 4 side by the ribs 40a and 42a. Here, the rib 40 a protrudes obliquely with respect to the front-rear direction of the vehicle 1 from the pillar outer cover 40 toward the inner side in the width direction of the vehicle 1. The rib 42 a protrudes obliquely with respect to the front-rear direction of the vehicle 1 from the flow path forming plate 42 toward the outer side in the width direction of the vehicle 1. When an impact force acts on the pillar outer cover 40 from the front of the vehicle 1, the ribs 40 a and 42 a receive the impact force in the bending direction and are broken by an impact force of a predetermined level or more.

  In addition, the flow passage 41 includes an inlet 41a through which air or rainwater flowing through the outer surface of the windshield 3 flows in, an air outlet 41b through which the rainwater flowing into the flow passage 41 is separated and flows out, and a flow passage A discharge port (not shown) is provided for discharging rainwater that has flowed into 41 and separated from air. The inflow port 41a is opened forward in a gap portion between the windshield 3 and the pillar outer cover 40, and the dimension of the gap between the windshield 3 and the pillar outer cover 40 is formed to a predetermined width dimension W1. . The air outlet 41b is opened rearward in the vicinity of the front door 4, and the dimension of the gap between the pillar outer cover 40 and the flow path forming plate 42 is formed to a predetermined width dimension W2 (W2 <W1). Has been. Further, the width dimension between the tip end portions of the ribs 40a and 42a in the flow passage 41 and the pillar outer cover 40 or the flow passage forming plate 42 located on the extension of the ribs 40a and 42a is determined by the windshield 3 of the inflow port 41a. And the width dimension W1 of the gap between the pillar outer cover 40 and the pillar outer cover 40. The discharge port is opened to the outside in the direction other than the glass portion of the front door 4 in the vicinity of the lower end portion and the upper end portion of the front pillar 20.

  Further, a groove 40b for guiding rainwater adhering to the outer surface of the pillar outer cover 40 to the lower end side or the upper end side of the front pillar 20 extends in the longitudinal direction at the center portion in the short direction of the outer surface of the pillar outer cover 40. Is formed.

  In the front pillar portion structure configured as described above, most of the air on both sides in the width direction of the windshield 3 of the traveling vehicle 1 flows along the outer surface side of the pillar outer cover 40 (see FIG. 2). One-dot chain line) partly flows through the flow passage 41 (two-dot chain line in FIG. 2), merges at the front door 4 part, and flows behind the vehicle 1. At this time, since the width dimension W2 of the air outlet 41b is formed smaller than the width dimension W1 of the inlet 41a, the flow velocity of air flowing out from the flow passage 41 is higher than the flow velocity of air flowing into the flow passage 41. Get faster.

  Further, when the vehicle 1 is traveling during rain, the rainwater adhering to the windshield 3 is wiped off by the wiper 3a, and a part of the rainwater flows toward both sides of the windshield 3 in the width direction. At this time, rainwater on both sides in the width direction of the windshield 3 flows into the flow passage 41 together with air from the inlet 41a provided between the windshield 3 and the pillar outer cover 40, and contacts the ribs 40a and 42a. Is separated from the air. The rainwater separated from the air flows along the ribs 40 a and 42 a and is discharged from the lower end portion or the upper end discharge port of the front pillar 20 to the outside in the direction other than the glass portion of the front door 4. Further, the air separated from the rainwater flows while meandering through the flow passage 41 and flows out from the air outlet 41b. For this reason, the rainwater separated in the flow passage 41 does not flow through the glass portion of the front door 4, and it is possible to prevent a decrease in visibility on the side surface of the passenger compartment due to the rainwater.

  Further, when the vehicle 1 is traveling during snowfall, the snow adhering to the windshield 3 is wiped off by the wiper 3a, and a part of the snow moves toward both sides of the windshield 3 in the width direction. At this time, the outer surface of the pillar outer cover 40 on the windshield 3 side is substantially the same height as the outer surface of the portion adjacent to the pillar outer cover 40 of the windshield 3, so that snow accumulates on both sides in the width direction of the windshield 3. It becomes possible to drop to the side of the vehicle 1 without.

  Further, when the traveling vehicle 1 and the pedestrian are in contact with each other, the pedestrian's head may be in contact with the front pillar portion 10. In this case, an impact force acts on the front pillar portion 10 from the front of the vehicle 1. At this time, since the ribs 40a and 42a provided on the pillar outer cover 40 and the flow passage forming plate 42 protrude obliquely with respect to the front-rear direction of the vehicle, an impact force is applied to the pillar outer cover 40 from the front of the vehicle 1. If it acts, a drag will not act with respect to a pedestrian from rib 40a, 42a, and an impact force will act in the direction where rib 40a, 42a bends. As shown in FIG. 3, the ribs 40a and 42a on which the impact force has acted are broken by an impact force of a predetermined level or more, thereby absorbing the impact force.

  Thus, according to the structure of the front pillar portion of the vehicle according to the present embodiment, air and rainwater circulated between the front pillar 20 and the pillar outer cover 40 through the front surface of the windshield 3 as the vehicle 1 travels. A possible flow passage 41 is provided. The flow passage 41 is formed so as to extend along the longitudinal direction of the front pillar 20 and an inflow port 41a for allowing air and rainwater flowing through the front surface of the windshield 3 to flow in. The ribs 40a and 42a for separating the rainwater from the air brought into contact with the inflowing rainwater, the air outlet 41b for discharging the air separated from the rainwater by the ribs 40a and 42a to the front door side, and the ribs 40a and 42a And a discharge port for discharging rainwater separated from the air in a direction other than the glass portion of the front door 4. As a result, the outer surface of the pillar outer cover 40 on the windshield 3 side can be formed to have the same height as the outer surface of the portion adjacent to the pillar outer cover 40 of the windshield 3. It is possible to reduce air resistance during traveling, and to prevent snow from accumulating on both sides in the width direction of the windshield 3 during traveling when the vehicle is snowing, thereby improving the appearance of the vehicle 1.

  Further, the ribs 40a, 42a provided on the pillar outer cover 40 and the flow passage forming plate 42 protrude obliquely with respect to the vehicle front-rear direction. As a result, when an impact force acts on the pillar outer cover 40 from the front of the vehicle 1, the resistance against the impact force from the front of the vehicle 1 does not act on the front of the vehicle. The head injury value of the pedestrian can be reduced, and the protection performance for the pedestrian of the vehicle 1 can be improved.

  Further, the ribs 40 a and 42 a have a property that can be broken by an impact force acting from the front of the vehicle 1. Thereby, it becomes possible to absorb the impact force acting from the front of the vehicle 1 by breaking the ribs 40a and 42a, so that the head injury value of the pedestrian at the time of contact with the pedestrian is further reduced. And it becomes possible to improve the protection performance with respect to the pedestrian of a vehicle.
