Description

  The present invention relates to a vehicle structure capable of introducing a pleasant wind toward an occupant during traveling of the vehicle.

  Even in an open car as well as a normal car, it is common to prevent the wind from entering the passenger compartment as much as possible so as not to give a passenger discomfort when driving.

  On the other hand, an attempt to positively introduce outside air into the vehicle and give the passenger a refreshing feeling has been studied (Cited document 1).

  In patent document 1, the open air introduction apparatus for open cars is proposed. This outside air introducing device is attached to the upper frame portion of the windshield. The outside air introducing device is provided with a deflection plate, and the outside air is introduced into the passenger compartment by adjusting the angle of the deflection plate so that the wind hits the forehead portion of the occupant.

  Regarding the present invention, a side door provided with an armrest is disclosed in Patent Document 2.

  The speed of a car changes constantly over a wide range. If it is a sports car that enjoys driving, such as an open car, the difference in speed will become even more severe.

  Wind (running wind) generated when the automobile travels varies with the vehicle speed, and therefore becomes stronger at higher speeds and weaker at lower speeds. Therefore, when the traveling wind is applied to the forehead portion of the occupant as in Patent Document 1, if the traveling wind becomes too strong and the traveling wind becomes too strong, the occupant is uncomfortable. In Patent Document 1, the traveling wind can be weakened by adjusting the angle of the deflection plate, but the operation is cumbersome and inconvenient.

  Furthermore, if a dedicated device is separately installed like the outside air introduction device of Patent Document 1, an increase in cost is inevitable. There is also a risk that the design of the vehicle will be damaged.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wind introduction structure that can provide an exhilarating feeling in a wide speed range without inconvenience by devising an existing vehicle structure.

  The disclosed vehicle wind introduction structure guides the traveling wind flowing on the side to the passenger compartment. This wind introduction structure is surrounded by a side door that covers the lower side of the passenger compartment so that it can be opened and closed, an upper edge of the side door, and a front pillar that extends obliquely upward from the vicinity of the front end of the upper edge. A triangular corner that covers the corner, a door mirror that is provided on the outer surface of the side door, and that is positioned so that at least a portion thereof faces the triangular corner, and a rear portion of the inner surface of the side door, An armrest on which the arm can be placed.

  The side door is provided with a wind guide portion that guides the traveling wind passing between the triangular corner portion and the door mirror to the armrest.

  And the said wind guide part is provided upwards in the site | part behind the said triangular corner part in the upper edge part of the said side door, and when an inner edge part gradually approaches an outer edge part, inner and outer width | variety is back. An upper surface portion that gradually narrows toward the upper surface, and an inclined surface portion that is provided so as to expand downward from the inner edge of the upper surface portion toward the armrest, and whose vertical width gradually increases toward the rear. Yes.

  That is, the wind introduction structure of the vehicle is formed by devising the shape of the vehicle itself so that the traveling wind flowing on the side of the vehicle is guided toward the armrest of the passenger compartment.

  Accordingly, since it is not necessary to newly provide a dedicated device or the like, an increase in installation cost can be avoided, and the design can be prevented from being greatly damaged.

  Specifically, the side door is provided with a wind guide portion having an upper surface portion and an inclined surface portion having a specific shape, and a corner portion surrounded by the upper edge portion of the side door and the front pillar by the wind guide portion. The traveling wind passing between the triangular corner portion covering the door mirror and the door mirror is guided to the armrest.

  Therefore, since the traveling wind is directed toward the arm part that is placed on the armrest and is relatively insensitive to external stimuli, even if the traveling wind becomes a little too strong, a refreshing feeling can be obtained, and the traveling wind Even if it becomes weak, the refreshing feeling is not lost immediately. As a result, it is possible to give the passenger a refreshing feeling in a wide speed range.

  Furthermore, the traveling wind that flows backward along the upper surface portion has a tapered shape in which the upper surface portion is biased outward, so that it tends to flow toward the rear while inclining in the same manner in the entire region. . Accordingly, the traveling wind can be guided toward the armrest without being disturbed along the inclined surface portion in a state where the air volume is uniformly distributed over the entire upper surface portion.

  As a result, since the traveling wind is evenly applied to the entire arm portion placed on the armrest without being locally biased, a refreshing feeling can be given to the occupant in a wider speed range.

  The upper surface portion and the inclined surface portion are preferably continuous with a continuous curved surface.

  If it does so, a driving | running | working wind can be guide | induced toward an armrest more smoothly and the dispersion | variation in an airflow can be suppressed.

  Furthermore, it is even more preferable that the degree of bending of the boundary portion between the inclined surface portion and the upper surface portion becomes gradually gentle toward the rear.

  By doing so, the airflow can be evenly distributed, and the traveling wind can be guided more smoothly along the inclined surface toward the armrest, so that the entire arm placed on the armrest can be guided. Traveling wind can be applied more evenly.

  The rear end of the base portion of the door mirror may be located behind the rear end of the triangular corner portion along the upper edge of the side door.

  If it does so, the position where air resistance disappears in the lower part between the triangular corner part and the door mirror is substantially the same on the inner side and the outer side, or the outer side is shifted rearward from the inner side. As a result, the traveling wind flowing in the lower portion between the triangular corner portion and the door mirror is easily caught in the passenger compartment side, and a lot of traveling wind can be introduced into the passenger compartment even at a low speed.

  Furthermore, in this case, it is preferable that the rear end of the triangular corner portion along the front pillar is located behind the rear end of the base portion of the door mirror.

  If it does so, the position where air resistance disappears in the upper part between a triangular corner part and a door mirror will shift outside on the back rather than the inside. As a result, the traveling wind flowing in the upper part between the triangular corner portion and the door mirror is easily caught on the opposite side of the passenger compartment, and it is possible to suppress unnecessary traveling wind from entering the passenger compartment.

  According to the disclosed wind introduction structure for a vehicle, an exhilarating feeling due to traveling wind can be obtained in a wide speed range without inconvenience of operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the following description is merely illustrative in nature and does not limit the present invention, its application, or its use.

  FIG. 1A illustrates a vehicle (automobile 1) of this embodiment. The automobile 1 is an open car, which is not shown, but is provided with a retractable roof so that driving can be enjoyed in a state where the range from the upper part to the rear part of the passenger compartment 2 is opened.

  Note that the present invention is suitable for an open car because the main purpose is to actively introduce a traveling wind into the passenger compartment 2 to give the passenger a refreshing feeling, but is not limited to an open car. For example, as shown in FIG. 1B, the present invention can be applied to a roofed automobile 1 ′ in which the upper part of the passenger compartment 2 is covered with a roof 3.

  In the automobile 1, the upper front portion of the passenger compartment 2 in which an occupant is accommodated is covered with a horizontally long windshield 11 that extends obliquely upward toward the rear. The side edges of the left and right sides of the windshield 11 are supported by the front pillars 12, and the upper edges of the windshield 11 are supported by the front beams 13 that span the upper ends of the left and right front pillars 12 and 12. ing.

  Lower side portions on the left and right sides of the passenger compartment 2 are respectively covered with side doors 14 and can be opened and closed. The front edge portion of the side door 14 is positioned so as to extend downward from the vicinity of the base end portion of the front pillar 12, and the side door 14 can swing to the side portion of the vehicle body via the front edge portion. It is supported.

  Each side door 14 is provided with a side window 15 that slides up and down from its upper edge portion 14a. Thereby, the upper part of the side surface of the passenger compartment 2 is covered by the side window 15 being closed (indicated by a virtual line in FIG. 1A) and opened by the side window 15 being opened. Yes.

  As shown in FIG. 2, when viewed from the side of the automobile 1, the front pillar 12 extends obliquely upward toward the rear from the vicinity of the front end portion of the upper edge portion 14 a of the side door 14. A triangular corner portion 16 is provided at a triangular corner portion surrounded by 12 and the front end portion of the upper edge portion 14 a of the side door 14.

  The triangular corner portion 16 of the automobile 1 includes a small window portion 16a made of triangular glass and a rear frame portion 16b provided along the rear edge of the small window portion 16a. The front edge of the small window portion 16a and the upper end of the rear frame portion 16b are fixed to the front pillar 12, and the lower edge of the small window portion 16a and the lower end of the rear frame portion 16b are fixed to the side portion of the vehicle body. ing.

  That is, the triangular corner portion 16 is provided on the vehicle body side, and when the side door 14 is opened, the upper edge portion 14 a of the side door 14 is separated from the lower portion of the triangular corner portion 16.

  A door mirror 19 is installed on a door panel 18 (a steel plate exterior part) covering the outer surface of the side door 14. The door mirror 19 is disposed in the vicinity of the front end portion of the upper edge portion 14 a of the side door 14. When viewed from the side, the triangular corner portion 16 and the upper portion of the door mirror 19 are positioned so as to face each other in the vehicle width direction so that the triangular corner portion 16 and the upper portion of the door mirror 19 overlap.

  By doing so, a passage (ventilation path 20) between the triangular corner portion 16 and the door mirror 19 is partitioned into a V shape or a U shape by the triangular corner portion 16 and the door mirror 19 when viewed from the front-rear direction. ) Is formed.

  An outer lever 18 a that is operated when the side door 14 is opened and closed from the outside is installed on the rear side of the upper portion of the door panel 18. The door mirror 19 may be retractable.

  As shown in FIGS. 3 and 4, a seat 21 on which an occupant sits is disposed in the passenger compartment 2 adjacent to the side door 14. An armrest 23 is provided at the rear of the door trim 22 (resin-made interior part) covering the inner surface of the side door 14 so that an occupant seated on the seat 21 can place its arm portion.

  Specifically, the armrest 23 is provided at an intermediate portion in the vertical direction in the rear portion of the side door 14. The armrest 23 projects from the surface of the door trim 22 toward the seat 21 and extends in the front-rear direction.

  In relation to the seat 21, the armrest 23 is positioned so as to face an intermediate portion in the vertical direction of the backrest 21a so that an occupant seated on the seat 21 can place the arm portion in a relaxed posture. In addition, an inner lever 22 a that is operated when the side door 14 is opened and closed from the inside is installed on the front side of the upper portion of the door trim 22.

  And in this motor vehicle 1, the wind guide part 30 is provided in the side door 14 so that driving | running | working wind may be positively introduce | transduced into the compartment 2 and a refreshing feeling may be given to a passenger | crew.

(Wind induction part)
The wind guide section 30 has a function of guiding the traveling wind passing through the ventilation path 20 between the triangular corner section 16 and the door mirror 19 to the armrest 23 when traveling with the side window 15 fully opened. The structure is devised so that the traveling wind is uniformly applied to the entire arm to be placed.

  If the driving wind is directed toward an area sensitive to external stimuli, such as the head of the passenger, if the driving wind becomes too strong, it may cause discomfort to the passenger, such as distorted hair and poor visibility. There is. On the other hand, if the traveling wind becomes too weak, it reacts sensitively to the change and the refreshing feeling is easily lost.

  On the other hand, the arm part is relatively insensitive to external stimuli, so even if the running wind becomes too strong, a refreshing feeling can be obtained, and even if the running wind becomes weak, the refreshing feeling is immediately lost. There is no such thing. That is, by guiding the traveling wind toward the arm part, it is possible to give the passenger a refreshing feeling in a wide speed range. Since there is no need for operation, there is no trouble.

  Furthermore, in this wind guide part 30, by making the traveling wind uniformly hit the arm part placed on the armrest 23 and preventing the traveling wind from hitting locally on the arm part, the range can be further increased. It is expanding further.

  The wind guide portion 30 is configured by processing the door trim 22 into a specific shape. Accordingly, since it is not necessary to newly provide a dedicated device or the like, an increase in installation cost can be avoided, and the design of the automobile 1 can be prevented from being greatly damaged.

  In FIG. 5, the schematic which looked at the part of the side door 14 from the inner side is shown.

  The upper portion of the door trim 22 extends in the front-rear direction along the inner side of the upper edge portion 14 a of the side door 14, and the portion located inside the triangular corner portion 16 is substantially orthogonal to the inner and outer surfaces of the side door 14. A flat front upper surface portion 31 that extends in the direction is provided. The front upper surface portion 31 has substantially the same inner and outer width (width in the vehicle width direction), and its rear end is located behind the triangular corner portion 16.

  A wind guide portion 30 is configured by a rear upper surface portion 32 extending continuously from the front upper surface portion 31 and an inclined surface portion 33 continuing from the rear upper surface portion 32.

  Specifically, the rear upper surface portion 32 has an outwardly tapered shape, an outer edge portion 32a that extends linearly in the front-rear direction, and an inner edge portion 32b that gradually approaches the outer edge portion 32a. The lateral width (internal / external width) gradually decreases toward the rear.

  The inclined surface portion 33 is provided so as to expand downward from the inner edge portion 32b of the rear upper surface portion 32 toward the armrest 23, and has a divergent shape in which the vertical width (vertical width) gradually increases toward the rear. ing.

  The rear upper surface portion 32 and the inclined surface portion 33 are connected by a continuous curved surface, and the degree of bending of the boundary portion 35 (the range partitioned by the imaginary line in FIG. 5) of the inclined surface portion 33 with the rear upper surface portion 32 is It is formed so as to become gradually gentle toward the rear.

  In FIG. 6, the figure which attached | subjected and represented the division line L with the fixed pitch in the front-back direction to the part of the wind guide part 30 is shown. The inner edge 32b of the rear upper surface portion 32 is linear, that is, a straight line or a slightly curved curve (dented toward the vehicle compartment 2).

  As shown in FIG. 7, the radius of curvature R of the boundary portion 35 increases toward the rear, and the degree of bending of the boundary portion 35 gradually decreases toward the rear. And the thickness of the door trim 22 is gradually reduced toward the rear, and the amount of protrusion of the lower portion of the inclined surface portion 33 toward the vehicle compartment 2 is gradually reduced toward the rear.

  Accordingly, the traveling wind that passes between the triangular corner portion 16 and the door mirror 19 and flows rearward along the rear upper surface portion 32 has a tapered shape in which the rear upper surface portion 32 is biased outward. As indicated by the arrow line in FIG. 5, the airflow is inclined in the same manner and flows inward and becomes easier to flow toward the rear. As a result, the traveling wind can be guided toward the passenger compartment 2 in a state where the air volume is evenly distributed over the entire rear upper surface portion 32 regardless of the strength of the traveling wind.

  The traveling wind thus guided is guided toward the lower armrest 23 without being disturbed along the inclined surface portion 33 that is continuous with the curved surface. As a result, the traveling wind is uniformly applied to the entire arm portion placed on the armrest 23 without being locally biased, so that even if the traveling wind becomes considerably strong, the passenger does not lose a refreshing feeling.

  Furthermore, in this automobile 1, even if it becomes low speed by devising these arrangements so that the traveling wind flowing between the triangular corner portion 16 and the door mirror 19 is further directed toward the passenger compartment 2, The refreshing feeling is difficult to lose.

  Specifically, as shown in FIG. 8, the rear end R <b> 1 of the portion (base portion 19 a) attached to the door panel 18 of the door mirror 19 is behind the triangular corner portion 16 along the upper edge portion 14 a of the side door 14. It is designed to be positioned at least rearward of the end (lower rear end R2).

  By doing so, the position where the air resistance disappears in the lower part of the ventilation path 20 is shifted rearward from the inner side. As a result, the traveling wind flowing in the lower part of the ventilation path 20 is likely to be caught in the passenger compartment 2 from the lower rear end portion, and a large amount of traveling wind can be introduced into the passenger compartment 2 even at a low speed. Become.

  Furthermore, the rear end (upper rear end R3) of the triangular corner portion 16 along the front pillar 12 is designed to be located behind the rear end R1 of the base portion 19a of the door mirror 19.

  By doing so, since the traveling wind flowing in the upper part of the ventilation path 20 is not easily caught in the passenger compartment 2 side, it is possible to eliminate the traveling wind that is difficult to guide to the armrest 23 and sensitive to external stimuli such as the head of the occupant. It is possible to suppress the traveling wind that may be directed to a certain part from entering the passenger compartment 2.

(Other)
The vehicle wind introduction structure according to the present invention is not limited to the above-described embodiment, and includes various other configurations.

  For example, the form of the automobile 1 described above is an example. For example, not only the 2-seater but a 4-seater may be used.

  The form of the triangular corner portion 16 is also an example. For example, the triangular corner portion may not have a glass small window portion. Although the embodiment has been described on the driver's seat side, it can also be applied to the passenger seat side.

  The shape of the wind guiding portion can be appropriately modified according to the design of the vehicle, such as the shape of a curved surface, as long as the traveling wind can be guided in a well-balanced manner to the entire arm portion mounted on the armrest.
