Description

Technical Field

[0001] The utility model relates to an air skirt device for a vehicle. Background Art

[0002] When a vehicle is running, the vehicle body collides with the headwind which is the air in the atmosphere, and thus air resistance is applied to the vehicle, and in this case, the resistance of the headwind causes a decrease in fuel efficiency. Therefore, a structure is required in the vehicle to improve aerodynamic performance and improve fuel efficiency by reducing the resistance of the headwind.

[0003] One embodiment of a device for improving aerodynamic performance includes an air skirt device that is disposed at the front side of a vehicle and reduces the amount of air introduced into the bottom of the vehicle body through the front bumper when the vehicle is traveling at high speed, thereby improving aerodynamic performance. Such an air skirt device may include: a first skirt that protrudes outward from the vehicle; a second skirt that is disposed below the first skirt and rotates to tilt after protruding together with the first skirt; a rotating shaft that is connected to the second skirt and rotates the second skirt; and a control unit that is connected to the rotating shaft and provides power to the rotating shaft to rotate the rotating shaft.

[0004] However, the conventional air skirt device has a problem that after the second skirt rotates, the second skirt sways due to the gap formed between the second skirt and the control unit due to the instability of the structure for fixing the second skirt. Therefore, there is a problem of reducing the headwind blocking performance of the second skirt. In addition, due to the swaying of the second skirt, there is a problem of damaging the second skirt and reducing durability. Utility Model Content

[0005] The utility model aims to provide a vehicle air skirt device, which is improved to prevent a gap from being formed between a second skirt and a control unit after the second skirt rotates.

[0006] According to one aspect of the utility model, a vehicle air skirt device is provided, which includes: a shell unit, in which an extension hole is formed; a skirt unit, which includes a first skirt and a second skirt, the first skirt is movably arranged in the shell unit and can protrude outward from the shell unit through the extension hole, and the second skirt can be rotated to tilt after the first skirt is fully extended; and a support unit, which is configured to move in the same direction as the moving direction of the first skirt and can rotatably support the tilted second skirt after the first skirt is fully extended.

[0007] The vehicle air skirt device may include a sliding cover fixedly mounted on the first skirt, wherein the support unit may be slidably disposed on the sliding cover.

[0008] The vehicle air skirt device may include a connecting rod unit, which is configured to be connected to the support unit and move the support unit, wherein the support unit may include: a first support block connected to the connecting rod unit; and a second support block connected to the first support block and movably disposed on the sliding cover.

[0009] The second supporting block of the supporting unit may include: a first moving portion, which is arranged inside the sliding cover; a second moving portion, which is arranged on an end of the first moving portion and outside the sliding cover; and a supporting protrusion, which is configured to be arranged on the second moving portion and movably support the second skirt.

[0010] The second moving portion of the second supporting block may be disposed to be inclined relative to the first moving portion.

[0011] The second skirt may include: a skirt body; a central rib configured to support the skirt body; side ribs disposed outside the central rib and configured to support the skirt body; and an elongated hole formed in the central rib and configured to accommodate the supporting protrusion of the second moving portion of the supporting unit in the elongated hole.

[0012] The elongated hole of the second skirt may include: a first area configured to contact the support protrusion before the second skirt is inclined; and a second area configured to contact the support protrusion after the second skirt is inclined.

[0013] The vehicle air skirt device may include a stopper rotatably coupled to the sliding cover in place and configured to contact the first moving portion of the second supporting block of the supporting unit.

[0014] The stopper may be pressed by the second supporting block of the supporting unit that moves in conjunction with movement of the link unit to enable a moving path of the first moving portion.

[0015] The vehicle air skirt device may include a side plate, which is fixedly mounted on the first skirt and is configured to provide a protrusion serving as a rotation center of the second skirt, wherein the rotation center of the second skirt may be arranged colinearly with the support protrusion of the second support block in a direction from the first support block of the support unit toward the second support block.

[0016] Since a gap is prevented from being formed between the second skirt and the operation control unit after the second skirt is rotated, the stability and headwind blocking performance of the second skirt can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

The vehicle air skirt device 1 may include a housing unit 1000, a skirt unit 2000, and an operation control unit 3000.

[0049] Figure 3 is a view showing a protrusion hole formed in the housing unit.

[0050] See also Figures 1 to 3 The housing unit 1000 may receive a portion of the skirt unit 2000 therein to guide movement of the skirt unit 2000, and may be coupled to the operation control unit 3000 to support the operation control unit 3000. The housing unit 1000 may include a first housing 1200 and a second housing 1400.

[0051] The first housing 1200 may support components of the operation control unit 3000 to be described below except for the actuator 3100. The first housing 1200 may support the actuator 3100 to be described below. In this case, the actuator 3100 may be provided outside the first housing 1200.

[0052] The second housing 1400 may be disposed in front of the first housing 1200 in the longitudinal direction. In this case, the longitudinal direction may have the same meaning as a direction from a cabin (not shown) of a vehicle toward an engine room (not shown). The second housing 1400 may be coupled to the first housing 1200 and supported by the first housing 1200. The second housing 1400 may cover an area in front of the first housing 1200 in the longitudinal direction.

[0053] As in Figure 3 As shown in FIG. 1 , a protrusion hole 1000a may be formed in the housing unit 1000. More specifically, the protrusion hole 1000a may be formed by closing one open side of the second housing 1400 using the first housing 1200. The protrusion hole 1000a formed in the housing unit 1000 may be an area that allows a portion of the skirt unit 2000 and a portion of the operation control unit 3000 provided in the housing unit 1000 to move.

[0054] Figure 4 is a view showing the second skirt.

[0055] refer to Figure 1 , Figure 2 and Figure 4The skirt unit 2000 may include a first skirt 2200 and a second skirt 2400, the first skirt being movably disposed in the housing unit 1000 and being protruded outward from the housing unit 1000 through the extension hole 1000a, and the second skirt 2400 being rotated to tilt after the extension of the first skirt 2200 is completed.

[0056] like Figure 1 As shown, the first skirt 2200 can be moved toward the outside of the housing unit 1000 by operating the control unit 3000 when it is set in the housing unit 1000. In this case, the first skirt 2200 can move along the height direction. In this case, the height direction can be a direction perpendicular to the longitudinal direction. The first skirt 2200 may include a skirt body.

[0057] The skirt body (hereinafter, referred to as "first skirt body 2220") may be a thin hollow frame. The first skirt body 2220 may be movable to protrude outward from the housing unit 1000 through the protrusion hole 1000a in the height direction. Therefore, the first skirt 2200 may block adverse wind.

[0058] The second skirt 2400 may be coupled to the first skirt 2200. More specifically, although the second skirt 2400 maintains a state of contact with the first skirt 2200, the second skirt 2400 may not be fixed to the first skirt 2200 and may be rotated by operating the control unit 3000 to be tilted relative to the first skirt 2200. The second skirt 2400 may include a skirt body, a central rib 2440, a side rib 2460, and an elongated hole.

[0059] The skirt body (hereinafter, referred to as "second skirt body 2420") may be a thin hollow frame. The second skirt body 2420 maintains a state of contact with the first skirt body 2220. The second skirt body 2420 may be connected to the side plate 3700 to be described below through a connecting bracket 3900 to be described below. Therefore, the second skirt body 2420 may not be separated from the first skirt 2200.

[0060] The central rib 2440 may be provided on a surface of the second skirt body 2420 that is not retained on the outside. The central rib 2440 may be provided as a plurality of central ribs 2440. The side ribs 2460 may be provided on the outside of the central rib 2440 in the width direction. In this case, the width direction may be a direction intersecting the longitudinal direction. The side ribs 2460 may be provided as a plurality of side ribs 2460. The central rib 2440 and the side ribs 2460 may support the second skirt 2400 to reinforce the strength of the second skirt 2400.

[0061] like Figure 4As shown, an elongated hole (hereinafter referred to as "first elongated hole 2480") may be formed in the central rib 2440. The first elongated hole 2480 may be provided in the central rib 2440 along the longitudinal direction. The first elongated hole 2480 may have a long hole shape. The first elongated hole 2480 may accommodate therein a supporting protrusion 3443 of a second supporting block 3440 of a supporting unit 3400 to be described below. The first elongated hole 2480 may include a first region 2482 and a second region 2484, the first region being in contact with the supporting protrusion 3443 of the second supporting block 3440 before the second skirt 2400 is tilted, and the second region being in contact with the supporting protrusion 3443 of the second supporting block 3440 after the second skirt 2400 is tilted.

[0062] Figure 5 is a view showing a state in which the operation control unit is coupled to the first skirt and the second skirt;

[0063] The operation control unit 3000 may be connected to the housing unit 1000 and the skirt unit 2000 and control the operation of the first skirt 2200 and the second skirt 2400. The operation control unit 3000 may include an actuator 3100, a link unit 3200, a sliding cover 3300, a support unit 3400, an auxiliary plate 3500, a stopper 3600, a side plate 3700, a track block 3800, and a connecting bracket 3900.

[0064] refer to Figure 2 and Figure 5 , the actuator 3100 may be coupled to the first housing 1200 of the housing unit 1000. In this case, the actuator 3100 may be disposed outside the first housing 1200. The actuator 3100 may be connected to an external power supply device (not shown) and generate power. In addition, the actuator 3100 may be connected to the connecting rod unit 3200. Therefore, the actuator 3100 may rotate the connecting rod unit 3200.

[0065] The link unit 3200 may be provided in the housing unit 1000. The link unit 3200 may be rotated by power generated by the actuator 3100 and connected to the support unit 3400 to move the support unit 3400. The link unit 3200 may include a first link 3220 coupled to the actuator 3100 and a second link 3240 rotatably coupled to the first link 3220 and coupled to the support unit 3400.

[0066] Fig. 6A is a view showing a state in which the sliding cover is coupled to the first skirt, and Figure 6B is a view showing a state in which the first supporting block is provided in the sliding cover.

[0067] refer to Figure 2, Figure 5 , Fig. 6A and Figure 6B , the sliding cover 3300 may be disposed in the housing unit 1000. Specifically, as in Fig. 6A As shown in FIG. 2 , the sliding cover 3300 may be fixedly installed in the first skirt 2200. The sliding cover 3300 may movably accommodate a portion of the support unit 3400. The sliding cover 3300 may be moved outward or inward from the housing unit 1000 together with the first skirt 2200.

[0068] like Figure 6B As shown, the sliding cover 3300 may include a second elongated hole 3320 and a third elongated hole 3340, which accommodate the first moving portion 3441 of the second supporting block 3440 of the supporting unit 3400, which will be described below. Specifically, the third elongated hole 3340 may be formed to have a greater length than a portion of the first moving portion 3441 of the second supporting block 3440. In this case, the third elongated hole 3340 may include: a third area 3341, in which the first moving portion 3441 remains set before the first supporting block 3420 moves; and a fourth area 3342, in which the first supporting block 3420 moves and the first moving portion 3441 is set.

[0069] Figure 7 is an exploded perspective view showing a support unit, Figure 8 is a cross-sectional view showing the first skirt, the sliding cover, the support unit and the auxiliary plate, and Fig. 9 is a cross-sectional view showing a state in which the supporting protrusion of the second supporting block is disposed in the elongated hole of the second skirt.

[0070] See also Figure 2 and Figures 7 to 9 , the support unit 3400 may be disposed in the housing unit 1000. Specifically, the support unit 3400 may be disposed between the first housing 1200 and the first skirt 2200 of the housing unit 1000. The support unit 3400 may move in the same direction as the moving direction of the first skirt 2200 and rotatably support the second skirt 2400, which is tilted after the extension of the first skirt 2200 is completed. The support unit 3400 may include a first support block 3420 and a second support block 3440.

[0071] like Figure 5 and Figure 8 As shown in FIG. 3 , the first support block 3420 may be connected to the link unit 3200. In addition, the first support block 3420 may be slidably coupled to a first auxiliary plate 3520 of the auxiliary plate 3500, which will be described below.

[0072] The first support block 3420 may include a first coupling protrusion 3421. The first coupling protrusion 3421 may be coupled to the second link 3240. Therefore, the first support block 3420 may move upward or downward in the height direction as the second link 3240 moves through the first coupling protrusion 3421.

[0073] The second supporting block 3440 may be coupled to the first supporting block 3420. The second supporting block 3440 may be movably disposed on the sliding cover 3300. The second supporting block 3440 may include a first moving portion 3441, a second moving portion 3442, a supporting protrusion 3443, and a second coupling protrusion 3444.

[0074] The first moving portion 3441 may be disposed inside the sliding cover 3300. The first moving portion 3441 may be moved in a height direction along the sliding cover 3300 by the first supporting block 3420, or may be slidably moved relative to the sliding cover 3300.

[0075] like Figure 5 and Fig. 9 As shown, the second moving portion 3442 may be disposed on an end of the first moving portion 3441. The second moving portion 3442 may be disposed outside the sliding cover 3300. The second moving portion 3442 may move in a height manner together with the first moving portion 3441. In addition, the second moving portion 3442 may have a greater width in a width direction than the first moving portion 3441. Therefore, when the second moving portion 3442 moves in a height direction, the second moving portion 3442 contacts the sliding cover 3300 to block further movement of the second support block 3440.

[0076] like Fig. 9 As shown in the figure, the support protrusion 3443 can be arranged on the second moving part 3442. The support protrusion 3443 can be arranged as a plurality of support protrusions 3443. The plurality of support protrusions 3443 can have a shape protruding toward each other. The support protrusion 3443 can be accommodated in the first elongated hole of the second skirt 2400. The support protrusion 3443 movably supports the second skirt 2400. The support protrusion 3443 can support the inclined second skirt 2400 in a state accommodated in the first elongated hole. This is to make the support protrusion 3443 block the further rotation of the second skirt 2400 so as to ensure as much additional headwind blocking area as possible in the process of manufacturing the second skirt 2400. In addition, the reason why the support protrusion 3443 supports the second skirt 2400 is to block the excessive rotation of the second skirt 2400 to prevent the formation of a gap between the first skirt 2200 and the second skirt 2400.

[0077] like Figure 8As shown in , the second coupling protrusion 3444 may be formed on each of the first moving part 3441 and the second moving part 3442. The second coupling protrusion 3444 may protrude from a surface that does not face the first skirt 2200 and the second skirt 2400 among the surfaces of the first moving part 3441 and the second moving part 3442. The second coupling protrusion 3444 may be coupled to the first supporting block 3420. The second supporting block 3440 may move in the height direction in linkage with the movement of the first supporting block 3420 through the second coupling protrusion 3444.

[0078] As described above, the support unit 3400 may be slidably disposed on the sliding cover 3300 and control the movement of the second skirt 2400 so that the second skirt 2400 moves independently of the first skirt 2200. Therefore, since the support unit 3400 eliminates the need for a separate power device for tilting the second skirt 2400, the support unit may reduce the manufacturing cost of the vehicle air skirt device.

[0079] Fig.10 is a sectional view showing a state in which the stopper is coupled to the slide cover and the second auxiliary plate, and Fig.11 is a view showing the second supporting block and the stopper in the first state. Fig.12 is a view showing the second supporting block and the stopper in a second state, Fig.13 is a view showing the second supporting block and the stopper in the third state.

[0080] See also Figure 2 , Figure 5 , Figure 8 and Figures 10 to 13 , the auxiliary plate 3500 may assist the movement of the supporting unit 3400. The auxiliary plate 3500 may include a first auxiliary plate 3520 and a second auxiliary plate 3540.

[0081] like Figure 8 and Figures 10 to 13 As shown, the first auxiliary plate 3520 may include a first plate body 3521 , a first accommodating groove 3522 , a second accommodating groove 3523 , and a third accommodating groove 3524 .

[0082] The first plate body 3521 may be fixedly installed in the first housing 1200 of the housing unit 1000. The first plate body 3521 may be formed of a combination of a rectangular panel and a protrusion protruding outwardly toward the skirt unit 2000 from one surface of the panel.

[0083] The first accommodating groove 3522 may be formed on the inner side of the protrusion constituting the first plate body 3521. The first accommodating groove 3522 may accommodate the second auxiliary plate 3540 therein. The second accommodating groove 3523 may be formed in an end region of the first plate body 3521. The second accommodating groove 3523 may be formed in a portion in which a portion of the protrusion forming the first plate body 3521 is bent. The second accommodating groove 3523 may be connected to a fourth accommodating groove 3543 (to be described below) of the second auxiliary plate 3540. The second accommodating groove 3523 may rotatably accommodate a portion of the stopper 3600 that moves downward in the height direction. The third accommodating groove 3524 may be formed in a central region of the first accommodating groove 3522. As Figure 8 , Fig.12 and Fig.13 As shown, the third receiving groove 3524 may form a space in which a portion of the second auxiliary plate 3540 may move.

[0084] The second auxiliary plate 3540 may be coupled to the first auxiliary plate 3520. The second auxiliary plate 3540 may include a second plate body 3541, a receiving hole 3542, and a fourth receiving groove 3543.

[0085] The second plate body 3541 is slidably disposed in the first receiving groove 3522 of the first auxiliary plate 3520. The second plate body 3541 may be formed of a combination of a rectangular panel and a protrusion protruding outwardly toward the skirt unit 2000 from one surface of the panel.

[0086] The receiving hole 3542 may be formed inside the protrusion forming the second plate body 3541. Figure 8 As shown in FIG. 3 , the receiving hole 3542 may movably receive therein the second coupling protrusion 3444 of the second supporting block 3440 of the supporting unit 3400. Therefore, the second supporting block 3440 of the supporting unit 3400 may ensure an additional moving distance in the height direction.

[0087] like Figures 11 to 13 As shown, the fourth accommodating groove 3543 may rotatably accommodate the stopper 3600 therein. The fourth accommodating groove 3543 may be provided in an end portion of the second plate body 3541 in the width direction. When the second plate body 3541 is provided in the first accommodating groove 3522 of the first auxiliary plate 3520, an open side of the fourth accommodating groove 3543 may be closed by a protrusion forming the first plate body 3521. When the second plate body 3541 moves in the height direction, the fourth accommodating groove 3543 may be provided at a position where the fourth accommodating groove 3543 communicates with the second accommodating groove 3523 of the first auxiliary plate 3520. Therefore, the fourth accommodating groove 3543 may communicate with the second accommodating groove 3523.

[0088] like Figure 2 , Fig.10 and Figures 11 to 13 As shown, the stopper 3600 is rotatably coupled to the sliding cover 3300 in position to contact the first moving portion 3441 of the second supporting block 3440 of the supporting unit 3400. More specifically, as shown in FIG. Fig.10 As shown, the stopper 3600 is rotatably coupled to the sliding cover 3300 and the second plate body 3541 of the second auxiliary plate 3540. In this state, the stopper 3600 is rotatably disposed in the fourth receiving groove 3543 of the second auxiliary plate 3540. The stopper 3600 may have a fan-shaped cross section. When the stopper 3600 is disposed in the fourth receiving groove 3543, the state in which the rotation is blocked by the protrusion forming the first plate body 3521 of the first auxiliary plate 3520 can be maintained.

[0089] like Figures 11 to 13 As shown, the stopper 3600 may be pressed by the second supporting block 3440 of the supporting unit 3400 that moves in conjunction with the movement of the link unit 3200 to enable the moving path of the first moving portion 3441 .

[0090] More specifically, if Figure 1 and Fig.11 As shown, in the first state S1 of the vehicle air skirt device 1 (in which the first skirt 2200 does not extend to the outside of the shell unit 1000), the stopper 3600 remains accommodated in the fourth accommodating groove 3543 of the second auxiliary plate 3540, and remains in a state where rotation is blocked by the protrusion of the first plate body 3521 forming the first auxiliary plate 3520.

[0091] In this state, when the support unit 3400 moves downward in the height direction through the link unit 3200, it is like Figure 11 to Figure 12 Specifically, when the first moving portion 3441 of the second supporting block 3440 of the supporting unit 3400 moves downward in the height direction, the stopper 3600 is pressed by the first moving portion 3441 of the second supporting block 3440 and moves downward in the height direction together with the second auxiliary plate 3540. In this state, the moving path of the first moving portion 3441 is maintained in a state in which it is not yet enabled.

[0092] As described above, when the stopper 3600 moves together with the second moving portion 3442 of the support unit 3400 and the second auxiliary plate 3540, the vehicle air skirt device 1 may enter the second state S2 in which the second skirt 2400 moves to protrude to the outside of the housing unit 1000. In the second state S2 of the vehicle air skirt device 1, the fourth accommodating groove 3543 of the second auxiliary plate 3540 may be disposed at a position where the fourth accommodating groove 3543 communicates with the second accommodating groove 3523 of the first auxiliary plate 3520. Therefore, the stopper 3600 may enter a rotatable state.

[0093] In this state, since the support unit 3400 is continuously moved downward in the height direction by the link unit 3200 rotated by the power generated by the actuator 3100, the first moving portion 3441 of the support unit 3400 maintains a state of continuously pressing the stopper 3600. In this case, since the fourth accommodating groove 3543 of the second auxiliary plate 3540 is in a state of being connected to the second accommodating groove 3523 of the first auxiliary plate 3520, the stopper 3600 can be rotated in place and set in the second accommodating groove 3523 of the first auxiliary plate 3520, similar to Figure 12 to Figure 13 Therefore, the moving path of the first moving part 3441 can be enabled.

[0094] As described above, the stopper 3600 can enable or close the moving path of the second support block 3440 according to the positions where the support unit 3400 and the second auxiliary plate 3540 move. Therefore, the stopper 3600 can block the undesired movement of the support unit 3400 to prevent the second skirt 2400 from accidentally moving (rotating) during the manufacturing process.

[0095] Fig.14 is a view showing a state where a side plate and a track block are set, Fig.15 2 is a view showing a state in which a connecting bracket connects the second skirt and the side plate.

[0096] refer to Figure 2 , Figure 5 and Fig.14 , the side plate 3700 may be fixedly installed in the first skirt 2200. The side plate 3700 may be arranged in the first skirt 2200 in the height direction. The side plate 3700 may be provided as a plurality of side plates 3700. The plurality of side plates 3700 may be provided to be spaced apart from each other in the width direction. A track groove in which the track block 3800 may be accommodated may be formed in the side plate 3700.

[0097] The side panel 3700 may include a central protrusion 3720. Figure 5As shown, the central protrusion 3720 may protrude from the side plate 3700 and rotatably support the second skirt 2400. The central protrusion 3720 is the rotation center of the second skirt 2400, and when the second skirt 2400 is moved by the second support block 3440 of the support unit 3400, the second skirt 2400 may rotate around the central protrusion 3720 as the rotation center to tilt.

[0098] See also Figure 2 , Figure 5 and Fig.14 , the track block 3800 may be fixedly mounted in the first housing 1200 of the housing unit 1000. The track block 3800 may be disposed in a track groove formed in the side plate 3700 in a state of being coupled to the first housing 1200. In this case, the track block 3800 may be disposed in a height direction. The track block 3800 may slidably support the side plate 3700.

[0099] Reference Figure 2 and Fig.15 , the connecting bracket 3900 may be disposed in the second skirt 2400. The connecting bracket 3900 may have The connecting bracket 3900 may connect the second skirt 2400 and the side plate 3700. That is, the second skirt 2400 may be supported by the connecting bracket 3900 connected to the side plate 3700. In addition, because the connecting bracket 3900 is coupled to the second skirt 2400, the second skirt 2400 may rotate around the central protrusion 3720 of the side plate 3700 together with the connecting bracket 3900.

[0100] Hereinafter, a process of operating the vehicle air skirt device 1 will be described.

[0101] Fig.16A 1 shows a first state of a vehicle air skirt device according to an embodiment of the present utility model, Fig. 16B 1 shows a second state of a vehicle air skirt device according to an embodiment of the present utility model, Fig. 16C 1 shows a third state of a vehicle air skirt device according to an embodiment of the present utility model, Fig.17A shows a shape of a state in which a supporting protrusion of a second supporting block of the supporting unit is in contact with a first region of a first elongated hole of a second skirt, and Fig. 17B The shape of the state in which the supporting protrusion of the second supporting block of the supporting unit is in contact with the second region of the first elongated hole of the second skirt is shown.

[0102] Reference Figures 1 to 16C , more specifically, in Fig.16AIn the first state S1 of the vehicle air skirt device 1 shown in FIG, the first skirt 2200 remains in a state of not moving toward the outside of the housing unit 1000 through the extension hole 1000a of the housing unit 1000. In this case, the end of the first skirt 2200 in the height direction is exposed to the outside of the second housing 1400. In addition, as Fig.11 As shown, in the first state S1 , the fourth receiving groove 3543 of the second auxiliary plate 3540 is disposed at a position where the fourth receiving groove 3543 is not communicated with the second receiving groove 3523 of the first auxiliary plate 3520 .

[0103] In this state, when power is generated by the actuator 3100, the first link 3220 connected to the actuator 3100 rotates, and the second link 3240 connected to the first link 3220 rotates to press the first support block 3420 of the support unit 3400, as if pulling the first support block 3420 downward in the height direction. Therefore, the first support block 3420 moves downward in the height direction. In this case, because the rotation of the stopper 3600 is blocked by the first auxiliary plate 3520, the second support block 3440, the second auxiliary plate 3540, and the stopper 3600 are like moving from one side to another side. Figure 11 to Figure 12 The process is the same as moving downwards.

[0104] In addition, since the track block 3800 is fixedly installed in the first housing 1200, the side plate 3700 is guided and moved by the track block 3800. Therefore, the first skirt 2200 coupled to the side plate 3700 moves downward in the height direction together with the side plate 3700, and the sliding cover 3300 also moves downward together with the first skirt 2200. In addition, the second skirt 2400 connected to the side plate 3700 by the connecting bracket 3900 also moves downward in the height direction together with the side plate 3700 and the connecting bracket 3900. Therefore, the state of the vehicle air skirt device 1 changes from the first state S1 to the second state S2.

[0105] exist Fig. 16B In the second state S2 of the vehicle air skirt device shown, the first skirt 2200 and the second skirt 2400 move downward in the height direction from the first state S1. In this state, when the power is continuously generated by the actuator 3100, the link unit 3200 rotates continuously. Therefore, since the support unit 3400 is pressed downward in the height direction by the link unit 3200, the first moving portion 3441 of the second support block 3440 of the support unit 3400 presses the stopper 3600.

[0106] In this case, if Fig.12As shown, since the fourth receiving groove 3543 of the second auxiliary plate 3540 is disposed at a position where the fourth receiving groove 3543 communicates with the second receiving groove 3523 of the first auxiliary plate 3520, when the first moving portion 3441 of the second supporting block 3440 presses the stopper 3600, the stopper 3600 can be rotated into place and rotated toward the second receiving groove 3523 of the first auxiliary plate 3520 and disposed in the second receiving groove 3523. Fig.13 As shown, the moving path of the first moving portion 3441 of the second supporting block 3440 may be enabled.

[0107] In a state where the moving path of the first moving portion 3441 is enabled, since the support unit 3400 moves downward through the link unit 3200, the first moving portion 3441 of the second support block 3440 can move from the third area 3341 of the third elongated hole 3340 of the sliding cover 3300 to the fourth area 3342, as shown in FIG. Fig. 16B As shown. Thus, further movement of the second support block 3440 is blocked.

[0108] As described above, in the process in which the movement of the second support block 3440 is blocked, the second moving portion 3442 of the second support block 3440 moves the second skirt 2400 further downward from the horizontal state in the second state S2. Because the connecting bracket 3900 is rotatably connected to the side plate 3700, the second skirt 2400 connected to the connecting bracket 3900 rotates together with the connecting bracket 3900 around the central protrusion 3720 of the side plate 3700. Therefore, the second skirt 2400 is tilted from the second state S2, and the vehicle air skirt device 1 enters the third state S3.

[0109] refer to Fig.17A and Fig. 17B , during the tilting process of the second skirt 2400, FIG. 17A to FIG. 17B The same process as described above, the first elongated hole 2480 may contact the support protrusion 3443 of the second support block 3440 in the order from the first area 2482 to the second area 2484. Thereby, further rotation of the second skirt 2400 is prevented, and thus the tilting of the second skirt 2400 stops.

[0110] As described above, the state of the vehicle air skirt device 1 according to one embodiment of the utility model can be changed from the first state S1 to the third state S3 to expand the range of blocking the headwind. Therefore, since the headwind is effectively blocked by the vehicle air skirt device 1, it is possible to prevent the components in the vehicle from being accidentally overcooled, and the possibility of foreign objects existing on the road surface colliding with the components in the vehicle can be reduced.

[0111] Fig.18It is a diagram showing the arrangement relationship between the support protrusion of the second support block of the support unit and the central protrusion of the side plate.

[0112] See also Fig.18 , the second moving portion 3442 of the second support block 3440 may be arranged to be inclined relative to the first moving portion 3441. More specifically, the second moving portion 3442 may be arranged to be gradually inclined toward the front of the first moving portion 3441 in the longitudinal direction. This is to ensure the distance between the central protrusion 3720 of the side plate 3700 and the supporting protrusion 3443 of the second support block 3440 of the supporting unit 3400 provided in the first elongated hole 2480 of the second skirt 2400. Therefore, after the second skirt 2400 is rotated to tilt, the generation of additional movement can be suppressed. Thus, the second skirt 2400 can be prevented from shaking after tilting, and thus the stability of the second skirt 2400 can be improved.

[0113] In addition, reference Fig.18 , the rotation center of the second skirt 2400 may be arranged in line with the support protrusion 3443 of the second support block 3440 in a direction from the first support block 3420 of the support unit 3400 toward the second support block 3440. More specifically, the support protrusion 3443 of the second support block 3440 may be arranged in line with the central protrusion 3720 of the side plate 3700 in the longitudinal direction.

[0114] Since the support protrusion 3443 of the second support block 3440 of the conventional air skirt device is disposed at a higher horizontal position than the center of the central protrusion 3720 of the side plate 3700, the support protrusion 3443 contacts the second area 2484 of the first elongated hole 2480 in the first state S1, and in the third state S3 where the tilting is completed, the support protrusion 3443 contacts the first area 2482 of the first elongated hole 2480. Therefore, in the third state S3, a phenomenon may occur in which the conventional second skirt 2400 moves toward the second area 2484 of the first elongated hole 2480 by headwind or vibration generated during the running of the vehicle.

[0115] Therefore, the structure of the present invention in which the support protrusion 3443 and the central protrusion 3720 are arranged in a colinear manner can prevent the second skirt 2400 in the third state S3 from moving in the first elongated hole 2480 due to headwind or vibration generated during vehicle driving.

[0116] In addition, the structure in which the support protrusion 3443 and the central protrusion 3720 of the present invention are arranged in a colinear manner can prevent the support protrusion 3443 of the second support block 3440 from excessively supporting the second skirt 2400 in the first state S1. In addition, in this structure, the support protrusion 3443 of the second support block 3440 can stably support the second skirt 2400. Fig. 17B After being tilted as shown in FIG. 2 , the second skirt 2400 droops in the direction of gravity.

[0117] According to one embodiment of the present invention, since a gap is prevented from being formed between the second skirt and the operation control unit after the second skirt is rotated, the stability and headwind blocking performance of the second skirt can be maintained.
