Description

  The present invention relates to a side sill mounting member.

It is known that the front and rear wheels of a vehicle involve air when traveling. When the front wheels and the rear wheels entrain air, air resistance is generated and fuel consumption is deteriorated.
In view of this, a technique has been proposed in which a current plate that regulates the air flow is arranged in front of the front wheels (see Patent Document 1). This baffle plate is housed inside the vehicle when traveling at a low speed, and is controlled to protrude forward of the front wheels when traveling at a high speed. As a result, the air resistance of the front wheels during high speed traveling is reduced.

However, there is almost no space for arranging such a current plate on the rear wheel side. For this reason, a fixed rectification unit has been proposed. For example, Patent Document 2 discloses a technique for forming a concave portion and a convex portion (vertical wall portion) in a side step molding disposed below a side sill of a vehicle so as to exert a rectifying function.
The side step molding is also called a mud guard, a side sill garnish, a side under spoiler, or the like.

However, it is necessary for the side step molding not to interfere with the unevenness of the ground. Further, since there is a possibility that the vehicle rides on a curb or the like at a low speed, it is necessary to ensure a sufficient clearance from the ground. For this reason, the vertical wall part of patent document 2 cannot be formed long enough. Therefore, the rectifying effect for the rear wheel according to Patent Document 2 is smaller than the rectifying effect for the front wheel according to Patent Document 1.
Thus, there is a demand for the rear wheel to realize a current plate that can adjust the amount of protrusion according to the traveling speed, as in the current plate of Patent Document 1.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a side sill mounting member capable of performing rectification on the rear wheels in accordance with the traveling state of the vehicle.

The present invention employs the following means.
A side sill mounting member according to the present invention is disposed in a side sill mounting member main body disposed below a side sill of a vehicle and a rear end wall portion of the side sill mounting member main body, and a rear wheel according to a traveling state of the vehicle. And a rear-wheel rectification unit that rectifies the vehicle.
Thereby, the side sill attachment member which can perform rectification | straightening with respect to a rear wheel according to the driving | running | working state of a vehicle is realizable. Therefore, the traveling wind blown to the front surface of the rear wheel is reduced, and the air resistance is reduced, thereby improving the fuel efficiency.

The rear wheel rectifying portion can be accommodated inside the rear end wall portion, and is disposed inside the rear end wall portion, a rectifying plate that protrudes from the lower surface of the rear end wall portion and faces the rear wheel. And a drive unit for moving the rectifying plate up and down.
Thereby, the baffle plate which can adjust protrusion amount can be arrange | positioned in the front surface of a rear wheel.

A guide for guiding the vertical movement of the current plate is provided.
Thereby, a baffle plate can be moved up and down characterly and smoothly.

The rectifying plate has a gear portion that meshes with the driving portion.
Thereby, even in a small space, a mechanism for moving the rectifying plate up and down can be constructed.

  The side sill mounting member body is a side step molding, a mud guard, a side sill garnish, or a side under spoiler.

Hereinafter, embodiments of a side sill mounting member according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of the vehicle A as viewed from the side. FIG. 2 is a perspective view showing the mudguard 10. FIG. 3 is a cross-sectional view showing the rear wheel rectification unit 20. FIG. 4 is a perspective view showing the rear wheel rectification unit 20.

A mudguard 10 is disposed below the side surface of the vehicle A.
The mud guard (side sill mounting member) 10 is housed in the mat guard main body 12 attached to the lower side of the side sill B and the mat guard main body 12 to reduce the traveling wind blown to the front side of the rear wheel T of the vehicle A. And a rear wheel rectifying unit 20.

The mat guard main body (side sill mounting member main body) 12 is mounted to prevent the pebbles and asphalt tar that are thrown up when the vehicle A travels from hitting the side sill B and the door D and being damaged. The mat guard body 12 is mounted for the purpose of improving the design of the side surface of the vehicle A.
The mat guard body 12 includes a center portion 13 disposed on the lower side portion of the side sill B, a front end wall portion 14 disposed on the front side portion, and a rear end wall portion 15 disposed on the rear side portion Ba. It is the hard resin member formed in.
The center portion 13 is a portion having a C-shaped cross section extending in the front-rear direction along the lower side portion of the side sill B. The front end wall portion 14 is a portion that extends upward from the front end of the lower side portion of the side sill B along the inner peripheral surface (front side portion of the side sill B) of the tire house in which the front wheel is accommodated. The rear end wall portion 15 is a portion extending upward along the inner peripheral surface (the rear side portion Ba of the side sill B) of the tire house in which the rear wheel T is accommodated from the rear end of the lower side portion of the side sill B.

The rear wheel rectifying unit 20 is accommodated in a small space S formed between the rear side portion Ba of the side sill B and the rear end wall portion 15 of the mat guard body 12 disposed on the rear side portion Ba. .
The rear wheel rectification unit 20 is disposed in front of the rear wheel T and reduces the traveling wind toward the rear wheel T, the rotation motor 25 that moves the rectification plate 22 up and down, and the vertical movement of the rectification plate 22. A pair of guides 28 for guiding.

  As shown in FIGS. 3 and 4, a space S is formed between the rear side portion Ba of the side sill B and the rear end wall portion 15. The space S is about 1 cm in the front-rear direction and about 10 cm in the left-right direction and the up-down direction. That is, the space S is a flat space whose main surface faces the front-rear direction.

The flat plate current plate 22 is a flat hard resin member accommodated in the space S.
The flat plate-like rectifying plate 22 can move so as to protrude downward from the bottom wall (lower surface) 15S of the rear end wall portion 15 of the mat guard body 12. A slit-like opening 16 through which the rectifying plate 22 is inserted is formed in the bottom wall 15S of the rear end wall portion 15 so as to extend in the left-right direction.
When the current plate 22 protrudes downward from the opening 16 of the bottom wall 15S of the rear end wall portion 15, about half or more of the width of the rear wheel T is shielded by the current plate 22 when viewed from the front.

The center in the left-right direction of the front surface 22S of the rectifying plate 22 is formed thicker than other portions. A rack (gear portion) 23 is formed on the side surface (left side surface or right side surface) of the thickly formed portion. That is, the rack 23 extends in the vertical direction and is formed so that the tooth surface faces the left direction or the right direction.
A flange 24 is formed on the upper end surface of the current plate 22.

Both right and left ends of the rectifying plate 22 are supported by a pair of guides 28 formed in grooves having a U-shaped cross section. The pair of guides 28 are erected on the bottom wall 15S of the rear end wall portion 15 and are disposed so that the U-shaped groove portions oppose each other.
The pair of guides 28 guide the vertical movement of the rectifying plate 22, and the flange 24 abuts on the tops of the pair of guides 28 to restrict the downward movement.

As shown in FIGS. 3 and 4, the rotary motor (driving unit) 25 is disposed along the bottom wall 15 </ b> S of the center portion 13 from the rear end wall portion 15 of the mat guard body 12.
The rotary motor 25 has a pinion gear 26 attached to the rotary shaft. The pinion gear 26 meshes with the rack 23 of the rectifying plate 22. Thereby, the rectifying plate 22 can be moved up and down by driving the rotary motor 25. The rotary motor 25 is controlled by a control unit (not shown).

The rear wheel rectification unit 20 operates as follows.
FIG. 5 is a perspective view showing the operation of the rear wheel rectification unit 20. FIG. 6 is a cross-sectional view showing the operation of the rear wheel rectification unit 20.
FIGS. 5A and 6A show before operation of the rear wheel rectification unit 20, and FIGS. 5B and 6B show after operation of the rear wheel rectification unit 20.

As shown in FIGS. 5A and 6A, when the vehicle A stops or travels at a low speed, the rectifying plate 22 is disposed at the uppermost position. That is, the current plate 22 is accommodated in the space S between the rear side portion Ba of the side sill B and the rear end wall portion 15 of the mat guard body 12.
In this state, the traveling wind passing between the mat guard body 12 and the ground blows on the front surface of the rear wheel T.

As shown in FIGS. 5B and 6B, when the vehicle A travels at a high speed, for example, 50 km or more, the rotary motor 25 is driven based on a command from a control unit (not shown). To do. The pinion gear 26 attached to the rotary motor 25 rotates and the rack 23 starts to move downward. That is, the current plate 22 moves downward while being guided by the guide 28. Thereby, the rectifying plate 22 protrudes downward (on the ground) from the bottom wall 15S of the rear end wall portion 15 of the mat guard body 12.
When the flange 24 of the rectifying plate 22 comes into contact with the top of the guide 28, the rotary motor 25 stops and the state where the rectifying plate 22 protrudes from the bottom wall 15S of the rear end wall portion 15 is maintained.
In this state, the traveling wind that passes between the mat guard body 12 and the ground is blown to the rectifying plate 22, so that the traveling wind blown to the front surface of the rear wheel T is reduced.

  As described above, when the vehicle A travels at a high speed, by reducing the traveling wind blown to the front surface of the rear wheel T, the air resistance caused by the rear wheel T entraining air is reduced. Therefore, the fuel consumption of the vehicle A can be improved compared to the conventional case. That is, it is possible to realize the side sill mounting member 10 that can rectify the rear wheel T according to the traveling state of the vehicle A.

Since the rack 23 that meshes with the pinion gear 26 attached to the rotary motor 25 is formed on the front surface 22S of the rectifying plate 22, the rear wheel rectifying unit 20 can be disposed in a small space S. That is, a mechanism for moving the rectifying plate 22 up and down can be constructed in the space S between the rear side portion Ba of the side sill B and the rear end wall portion 15 of the mat guard body 12.

  The various shapes and combinations of the constituent members shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  Although the case where the rotary motor 25 is used as the drive unit that moves the rectifying plate 22 up and down has been described, the present invention is not limited thereto. Instead of the rotary motor 25, a linear actuator such as a linear motor or a cylinder mechanism may be used.

  Although the case where the guide 28 for guiding and supporting the current plate 22 is provided has been described, the guide may be integrally formed on the rear end wall portion 15.

  Although the mud guard has been described as the side sill mounting member, the present invention is not limited to this. It may be a side step molding, a side silgarnish, or a side under spoiler.

  Although the rectifying plate 22 has been described with respect to the case where the gear portion 23 that meshes with the driving portion 25 is formed on the surface (front surface 22S) facing the driving portion 25, the present invention is not limited thereto. A gear portion may be formed on the side end face of the rectifying plate 22.
