[0137] The above-described arrangement of the light sources serves to minimize the loss of light illuminating the sheet unit 2000 to prevent deterioration in the designability of the front side of the vehicle.

[0138] Fig.17 is a view showing a state in which the 1-1 sheet module closes the first inlet hole and the 2-1 sheet module closes the second inlet hole, and Fig.18 is a view showing a state in which a 1-1 sheet module opens a first inlet hole and a 2-1 sheet module opens a second inlet hole. Fig.19 is a view showing a state in which the 1-2 sheet module closes the first inlet hole and the 2-2 sheet module closes the second inlet hole, and Fig. 20 is a view showing a state in which a 1-2 sheet module opens a first inlet hole and a 2-2 sheet module opens a second inlet hole.

[0139] See also Fig.17 and Fig.18First, the 1-1 sheet module 2200a and the 2-1 sheet module 2400a are located at the first position P1 where the first inlet hole 1440 and the second inlet hole 1450 are closed.

[0140] In this state, when the rotating shaft 4400 is rotated by the actuator 4200, the first shaft link 5430 of the first opening and closing unit 5000 coupled to the rotating shaft 4400 rotates together with the rotating shaft 4400, and the first shaft link 5430 generates a force that pulls the second shaft link 5440 toward the rotating shaft 4400. Therefore, the second shaft link 5440 moves toward the rotating shaft 4400, and the second shaft link 5440 pulls the first moving block 5200. Therefore, the first moving block 5200 moves toward the rotating shaft 4400.

[0141] Since the first moving block 5200 is in a state of being movably accommodated in the first accommodation portion 1240 of the fixed housing 1000, the first moving block 5200 moves toward the rotation axis 4400 in the first accommodation portion 1240. In this case, as the first moving block 5200 moves, the first sheet link 5410 and the second sheet link 5420 connected to the first moving block 5200 are pulled by the first moving block 5200. In this case, the first sheet link 5410 and the second sheet link 5420 rotate to approach each other.

[0142] Therefore, the 1-1 sheet module 2200a coupled to the first sheet link 5410 can be rotated to open the first inlet hole 1440, and the 2-1 sheet module 2400a coupled to the second sheet link 5420 can be rotated to open the second inlet hole 1450, so that the 1-1 sheet module 2200a and the 2-1 sheet module 2400a can be set at the second position P2. Therefore, the first inlet hole 1440 and the second inlet hole 1450 are opened. At the same time, the first moving block 5200 contacts the first stopper frame 1240a of the first accommodating portion 1240 of the fixed housing 1000 and is prevented from moving.

[0143] Then refer to Fig.19 and Fig. 20 , the 1-2 sheet module 2200b and the 2-2 sheet module 2400b are disposed at a first position P1 where the first inlet hole 1440 and the second inlet hole 1450 are closed.

[0144] In this state, when the rotating shaft 4400 is rotated by the actuator 4200, the third shaft link 6430 of the second opening and closing unit 6000 coupled to the rotating shaft 4400 rotates together with the rotating shaft 4400, and the third shaft link 6430 generates a force that pulls the fourth shaft link 6440 toward the rotating shaft 4400. Therefore, the fourth shaft link 6440 moves toward the rotating shaft 4400, and the fourth shaft link 6440 pulls the second moving block 6200. Therefore, the second moving block 6200 moves toward the rotating shaft 4400.

[0145] Since the second moving block 6200 is in a state of being movably accommodated in the second accommodation portion 1250 of the fixed housing 1000, the second moving block 6200 moves toward the rotation axis 4400 in the second accommodation portion 1250. In this case, as the second moving block 6200 moves, the third sheet link 6410 and the fourth sheet link 6420 connected to the second moving block 6200 are pulled by the second moving block 6200. In this case, the third sheet link 6410 and the fourth sheet link 6420 rotate to approach each other.

[0146] Therefore, the 1-2 sheet module 2200b coupled to the third sheet link 6410 can be rotated to open the first inlet hole 1440, and the 2-2 sheet module 2400b coupled to the fourth sheet link 6420 can be rotated to open the second inlet hole 1450, so that the 1-2 sheet module 2200b and the 2-2 sheet module 2400b can be set at the second position P2. Therefore, the first inlet hole 1440 and the second inlet hole 1450 are opened. At the same time, the second moving block 6200 contacts the second stopper frame 1250a of the second accommodating portion 1250 of the fixed housing 1000 and is prevented from moving.

[0147] As described above, the vehicle air flap system 1 according to one embodiment of the present disclosure can simultaneously open a plurality of inlet holes arranged in the height direction.

[0148] Hereinafter, a state in which the sheet unit 2000 is illuminated according to a transmission path of light will be described.

[0149] Fig.21 : is a view showing a transmission path of light generated by a first light source in a state where a 1-1 sheet module or a 2-1 sheet module closes a first entrance hole.

[0150] The light generated by the lighting unit 7000 may be refracted through the first and second serrations 2211 and 2411 of the sheet unit 2000 and emitted to the outside of the sheet unit 2000. In the present embodiment, an example of emitting light through the first serration 2211 will be described.

[0151] Reference Fig.21, when the 1-1 sheet module 2200a or the 2-1 sheet module 2400a is set at the first position P1 with the first entrance hole closed, when light is generated by the first light source 7210 of the first lighting module 7200, the light can pass through the first cover sheet 2220 and the first sawtooth body 2211 and pass through the first sheet module 2200 to the outside.

[0152] More specifically, first, light that passes through the first diffusion cover 7240 and enters the first base 2211a of the first sawtooth body 2211 moves toward the 1-1 sawtooth portion 2211b. The light that moves toward the 1-1 sawtooth portion 2211b collides with the 1-1 sawtooth portion 2211b and is then refracted therethrough to move toward the 1-2 sawtooth portion 2211c. The light that moves toward the 1-2 sawtooth portion 2211c passes through the first pattern portion 2211c1 or the second pattern portion 2211c2. The light refracted while passing through the first pattern portion 2211c1 or the second pattern portion 2211c2 eventually passes through the first cover sheet 2220 and moves to the outside of the first sheet module 2200.

[0153] Then, the light passing through the first diffusion cover 7240 and entering the first base 2211a of the first sawtooth body 2211 moves toward the 1-2 sawtooth portion 2211c. The light moving toward the 1-2 sawtooth portion 2211c passes through the first pattern portion 2211c1 or the second pattern portion 2211c2. The light refracted while passing through the first pattern portion 2211c1 or the second pattern portion 2211c2 may finally pass through the first cover sheet 2220 and move to the outside of the first sheet module 2200.

[0154] Then, the light passing through the first diffusion cover 7240 passes through the first cover sheet 2220 instead of the first serration body 2211 , and finally moves to the outside of the first sheet module 2200 .

[0155] As described above, the light is diffused while colliding with the plurality of sawtooth portions, and is diffused to the entire area of ​​the first sheet module 2200. Therefore, since the light generated by the first light source 7210 illuminates the first sheet module 2200 through various paths, when the first sheet module 2200 closes the first inlet hole 1440 of the fixed housing 1000, the designability of the front side of the vehicle can be improved.

[0156] In the present embodiment, an example in which light is transmitted through the first sawtooth body 2211 is described, but it is not limited thereto. Since the second sheet module 2400 and the second lighting module 7400 have shapes symmetrical to those of the first sheet module 2200 and the first lighting module 7200, light moving inside the second sheet module 2400 can be transmitted from the inside of the second sheet module 2400 to the outside by the same principle.

[0157] Fig. 22: is a view showing a transmission path of light generated by a first light source in a state where a first entrance hole is opened in a 1-1 sheet module or a 2-1 sheet module.

[0158] Reference Fig. 22 , in a state where the 1-1 sheet module 2200a or the 2-1 sheet module 2400a is disposed at the second position P2 in which the first inlet hole 1440 is opened, the light generated by the first light source 7210 may not pass through the inside of the 1-1 sheet module 2200a or the inside of the 2-1 sheet module 2400a. In addition, the light may pass only through the area where the 1-1 sheet module 2200a overlaps with the first lighting module 7200 and the area adjacent to the area where the 1-1 sheet module 2200a overlaps with the first lighting module 7200, and may pass through the area where the 2-1 sheet module 2400a overlaps with the first lighting module 7200 and the area adjacent to the area where the 2-1 sheet module 2400a overlaps with the first lighting module 7200.

[0159] The reason for having the above structure is that, in a state where the 1-1 sheet module 2200a or the 2-1 sheet module 2400a opens the first entrance hole 1440, the interior of the fixed housing 1000 is visible due to the light emitted by the first light source 7210. Therefore, in a state where the 1-1 sheet or the 2-1 sheet opens the first entrance hole 1440 to prevent the interior of the fixed housing 1000 from being visible due to the light emitted by the first light source 7210, movement can be performed within a range where the transmission path of light is limited.

[0160] In this embodiment, the relationship between the 1-1 chip module 2200a, the 2-1 chip module 2400a and the first lighting module 7200 has been described, but is not limited thereto and can be equally applied to the relationship between the 1-2 chip module 2200b, the 2-2 chip module 2400b and the second lighting module 7400.

[0161] As mentioned above, reference Fig.21 and Fig. 22 When the sheet unit 2000 closes the inlet hole of the first column and the inlet hole of the second column, the sheet unit 2000 is illuminated by the light generated by the lighting unit 7000, and when the sheet unit 2000 opens the inlet hole of the first column and the inlet hole of the second column, the sheet unit 2000 may not be illuminated. Therefore, the vehicle air flap system 1 of the present embodiment can prevent the deterioration of the aesthetics by preventing the deterioration of the designability of the front side of the vehicle.

[0162] Hereinafter, an arrangement relationship between the sheet unit 2000 and the lighting unit 7000 will be described.

[0163] Fig.23A , Fig. 23B and Fig.24 A view illustrating the arrangement relationship between the sheet unit and the lighting unit is shown.

[0164] Reference Fig.23A and Fig. 23B , the first cover sheet 2220 of the first sheet module 2200 may include a first surface 2221 forming a first corner portion C1, a second surface 2222, and a third surface 2223 forming a second corner portion C2 together with the second surface 2222. In addition, the second cover sheet 2420 of the second sheet module 2400 may include a fourth surface 2421 forming a third corner portion C3, a fifth surface 2422, and a sixth surface 2423 forming a fourth corner portion C4 together with the fifth surface 2422.

[0165] In this case, if Fig. 23B As shown, the first lighting module 7200 can be disposed behind the first corner C1 of the first cover piece 2220 when the first cover piece 2220 opens the first inlet hole 1440 , and can be disposed behind the second corner C2 of the first cover piece 2220 when the first cover piece 2220 closes the first inlet hole 1440 .

[0166] In addition, if Fig.23A As shown, the second lighting module 7400 can be set behind the third corner C3 of the second cover piece 2420 when the second cover piece 2420 opens the second inlet hole 1450, and can be set behind the fourth corner C4 of the second cover piece 2420 when the second cover piece 2420 closes the second inlet hole 1450.

[0167] This is to prevent light generated by the first light source 7210 and the second light source 7410 from diffusing to the outside of the first cover sheet 2220 and the second cover sheet 2420 by preventing light from escaping from the first cover sheet 2220 and the second cover sheet 2420 in a state where the first sheet module 2200 and the second sheet module 2400 close the first inlet hole 1440. Therefore, it is possible to prevent the designability of the front side of the vehicle from being deteriorated.

[0168] Furthermore, this is to prevent deterioration of designability of the vehicle front side by preventing the first and second light sources 7210 and 7410 from being exposed to the outside of the first and second sheet modules 2200 and 2400 in a state where the first and second sheet modules 2200 and 2400 open the first inlet holes 1440 .

[0169] refer to Fig.24 The first light source 7210 may be disposed to be spaced apart from the first sheet module 2200 with the first diffusion cover 7240 interposed therebetween, and the second light source 7410 may be disposed to be spaced apart from the second sheet module 2400 with the second diffusion cover 7440 interposed therebetween. This is to ensure that the light emitted by the first light source 7210 and the second light source 7410 can be sufficiently diffused to the distance of the first sheet module 2200 and the second sheet module 2400.

[0170] To this end, the distance between the first sheet module 2200 and the first light source 7210 is preferably set within a range of 8 mm to 10 mm. This is because, when the distance between the first sheet module 2200 and the first light source 7210 and the distance between the second sheet module 2400 and the second light source 7410 are 8 mm or less, since a phenomenon may occur in which light is concentrated in an area where the first sheet module 2200 and the second sheet module 2400 contact each other and combine in the area, a problem that only a specific area is illuminated may occur. In addition, this is because, when the distance between the first sheet module 2200 and the first light source 7210 and the distance between the second sheet module 2400 and the second light source 7410 are 10 mm or more, a problem may occur in which light escapes from the first sheet module 2200 and the second sheet module 2400 and cannot illuminate the first sheet module 2200 and the second sheet module 2400 or the first sheet module 2200 and the second sheet module 2400 are dimly illuminated.

[0171] In addition, the reason why the first light source 7210 is disposed to be spaced apart from the first sheet module 2200 and the first diffusion cover 7240 is interposed therebetween, and the reason why the second light source 7410 is disposed to be spaced apart from the second sheet module 2400 and the second diffusion cover 7440 is interposed therebetween is to prevent the first sheet module 2200 and the second sheet module 2400 from colliding with the first lighting module 7200 and the second lighting module 7400 when the first sheet module 2200 and the second sheet module 2400 are rotated. For this reason, the distance between the first sheet module 2200 and the first diffusion cover and the distance between the second sheet module 2400 and the second diffusion cover are preferably set to 2 mm or more.

[0172] Fig.25 is a view showing a first lens block according to another embodiment.

[0173] Reference Fig.25 , the 1-1 sawtooth portion 2211b of the first sheet module 2200 may have a shape in which the cross section gradually decreases from the lower side toward the upper side in the height direction. This is to reduce the vertical distance relative to the light emitted by the first light source 7210 to allow the light to reach the upper end of the 1-1 sawtooth portion 2211b in the height direction.

[0174] According to one embodiment of the present disclosure, since the sheet is not provided behind the cover, it is possible to prevent the deterioration of the designability of the front side of the vehicle.

[0175] In addition, according to one embodiment of the present disclosure, since the sheet unit can be illuminated by the lighting unit, the designability of the front side of the vehicle can be improved.

[0176] Although the present disclosure is described above with reference to exemplary embodiments, it will be appreciated by those skilled in the art that various modifications and changes may be made to the present disclosure without departing from the spirit and scope of the present disclosure. In addition, it will be appreciated that the differences associated with modifications and changes fall within the scope of the present disclosure.
