Alternatively, the dust removal device 100 may be provided in the same number as the number of tires (T) of the vehicle (V). Hereinafter, for convenience of explanation, the dust removal device 100 will be described focusing on the case where the dust removal device 100 is provided in the same number as the tires T of the vehicle V and is disposed at the rear of each tire T.

The dust removal device 100 is disposed at the rear of the tire (T) to collect dust generated while the vehicle (V) is running, especially dust generated as the tire (T) wears, and can remove it using a laser. .

In one embodiment, the dust removal device 100 may include a housing 110 and a laser irradiation device 120.

The housing 110 is disposed at the rear of the tire (T) and may have an inlet (111) through which dust generated while the vehicle (V) is running is introduced. The size and shape of the housing 110 are not particularly limited, and may be appropriately selected in consideration of the size, shape, and other characteristics of the vehicle (V) and/or tire (T) on which the dust removal system 10 is installed. .

In one embodiment, as shown in FIGS. 3 and 4, the housing 110 may have a shape in which the cross-sectional area narrows toward the rear. Through this, the dust collected inside the housing 110 is more integrated and transferred to the laser irradiation device 120, thereby increasing dust removal efficiency. For example, the housing 110 may be a hexahedron whose lower surface is inclined upward toward the rear.

The laser irradiation device 120 is disposed on one side of the housing 110 and removes dust collected inside the housing 110 by irradiating a laser.

In one embodiment, the laser irradiation device 120 may be disposed at the rear end of the housing 110, that is, facing the entrance 111. And the laser irradiation device 120 may be provided with an area capable of receiving dust introduced through the inlet 111. For example, as shown in FIGS. 3 and 4, the laser irradiation device 120 includes a main body that covers the rear end of the housing 110, and the introduced dust can be accommodated inside the main body.

In one embodiment, the laser irradiation device 120 may further include a plurality of first laser oscillation elements 121. A plurality of first laser oscillation elements 121 are disposed on the inner surface of the laser irradiation device 120, and can be removed by irradiating a laser to dust.

As shown in FIGS. 3 and 4 , the first filter 130 is disposed at the inlet 111 of the housing 110 and may have a net shape to filter out foreign substances larger than a predetermined size. The first filter 130 allows dust to pass through the interior of the housing 110 and filters remaining foreign substances (for example, tree branches, trash, etc.) that have a volume larger than the dust.

In one embodiment, the dust removal device 100 may further include a second filter 140.

As shown in FIGS. 3 and 4, the second filter 140 is disposed on the inner surface of the housing 110 and may include a plurality of protrusions (P). For example, the second filter 140 is disposed on the inside of the lower surface of the housing 110 and can filter foreign substances flowing into the inlet 111.

In one embodiment, the protrusion P may have a pillar shape extending upward from the inner surface of the housing 110. A plurality of protrusions (P) are disposed on the inner surface of the housing 110 at predetermined intervals, and foreign matter moves along the housing 110 and comes into contact with the protrusions (P), between the protrusions (P) and the protrusions (P). can be captured. And dust, which has smaller particles compared to foreign substances, may move to the laser irradiation device 120 without being collected by the second filter 140.

In one embodiment, the protrusion P may have an upper surface inclined toward the rear. For example, as shown in FIG. 4, a plurality of protrusions (P) are arranged at predetermined intervals along the longitudinal direction of the housing 110, and the upper surface of each protrusion (P) faces the rear of the housing 110. Can slope upward. Accordingly, in the longitudinal direction of the housing 110, the upper surfaces of the plurality of protrusions (P) may contact the imaginary line (L). The virtual line (L) extends from the upper surface of the projection (P) located at the front end of the housing 110 among the plurality of projections (P), passes through the upper surface of the projection (P) located at the rear end of the housing 110, and forms the housing 110. ) may extend to the edge where the rear end meets the front end of the laser irradiation device 120.

Through this configuration, the second filter 140 can remove foreign substances contained in the outside air, and at the same time allow the outside air to move smoothly to the rear end of the housing 110 along the upper surface of the plurality of protrusions (P). .

In one embodiment, the dust removal device 100 may further include a sensor (S). The sensor S is disposed on one side of the housing 110 and can measure the amount of dust collected inside the housing 110. For example, the sensor S may be placed on the outer surface of the housing 110 to measure the volume or weight of dust. The sensor S may transmit the measured volume or weight of dust to the controller 200.

Referring again to FIG. 1, the controller 200 may be connected to the dust removal device 100. For example, the controller 200 may be connected to a plurality of dust removal devices 100 by wire or wirelessly and control the laser irradiation device 120. The controller 200 can control the laser irradiation device 120 through a preset program or algorithm to remove dust by irradiating laser. Alternatively, the controller 200 may control the laser irradiation device 120 by remotely receiving instructions from a user riding in the vehicle V or instructions from a user outside the vehicle V.

In one embodiment, the controller 200 may control the laser irradiation device 120 to irradiate the laser when the weight or volume of dust detected by the sensor S exceeds a preset value.

Figure 5 shows a cross section of a dust removal device (100A) according to another embodiment of the present invention.

The dust removal device 100A may have a different housing 110A and a second filter 140A compared to the dust removal device 100 described above. The remaining configuration of the dust removal device 100A may be the same as that of the dust removal device 100, and detailed description thereof will be omitted.

The housing 110A may have a shape in which the cross-sectional area narrows from the inlet 111A toward the rear end. For example, the housing 110A may have a parallelogram cross-sectional shape, as shown in FIG. 5 . That is, the upper and lower surfaces of the housing 110A may be inclined so that the cross-sectional area narrows from the inlet 111A toward the rear end. Accordingly, as the dust flowing into the housing 110A moves backward, a more concentrated effect can be achieved.

In another embodiment, the housing 110A may have both sides in addition to the upper and lower surfaces inclined so that the cross-sectional area narrows from the inlet 111A toward the rear end.

The second filter 140A may be disposed on an inclined surface of the housing 110A. For example, as shown in FIG. 5, the second filter 140A may be disposed on the inclined upper and lower surfaces of the housing 110A, respectively. The upper surface of the protrusion P included in the second filter 140A may have a predetermined slope.

For example, the plurality of protrusions P disposed on the lower surface of the housing 110A may have an imaginary line L1 extending from the upper surface. The virtual line L1 may extend along the inlet 111A of the housing 110A from the corner where the rear end of the housing 110A contacts the laser irradiation device 120A. Additionally, the plurality of protrusions P disposed on the upper surface of the housing 110A may have an imaginary line L2 extending the upper surface. The virtual line L2 may extend along the inlet 111A of the housing 110A from the corner where the rear end of the housing 110A contacts the laser irradiation device 120A.

In another embodiment, the second filter 140A may be disposed on both sides of the housing 110A in addition to the lower and upper surfaces. For example, when both sides of the housing 110A have a shape inclined toward the rear, the second filter 140A can be disposed on both sides of the housing 110A to remove foreign substances.

Through this configuration, the dust removal device 100A can more effectively remove foreign substances using the second filter 140A.

Figure 6 shows a dust removal device (100B) according to another embodiment of the present invention, and Figure 7 shows a cross section of Figure 6.

The dust removal device 100B may further include a collection unit 150B compared to the dust removal device 100 described above. The remaining configuration of the dust removal device 100B may be the same as that of the dust removal device 100, and detailed description thereof will be omitted.

In one embodiment, the collection unit 150B may be a box-shaped member with open front and back sides. Additionally, the collection unit 150B has an internal space 151B, and dust introduced through the inlet 111B may flow into the internal space 151B.

In one embodiment, the outer surface of the collection unit 150B may be arranged to be spaced apart from the inner surface of the housing 110B. Additionally, a foreign matter receiving area 160B may be disposed between the housing 110B and the collection unit 150B.

As shown in FIGS. 6 and 7, the foreign matter receiving area 160B is an area formed between the inner surface of the housing 110B and the outer surface of the collection unit 150B, and accommodates the foreign matter introduced from the inlet 111B. It can be. The received foreign matter is a foreign matter not filtered by the first filter 130B, and may be a particle larger in size than dust.

Through this configuration, foreign matter with a relatively large particle size is filtered through the first filter 130B and the foreign matter receiving area 160B, and the remaining dust is transferred to the internal space 151B of the collection unit 150B, thereby improving dust removal efficiency. can increase.

In another embodiment, a second filter (not shown) composed of a plurality of protrusions may be additionally disposed in the internal space 151B and/or the foreign matter receiving area 160B.

In one embodiment, the collection unit 150B may have a shape in which the separation distance between the outer surface and the inner surface of the housing 110B gradually increases toward the inlet 111B. For example, as shown in FIG. 6, the collection unit 150B may be directly connected to the rear end of the housing 110B. That is, the collection unit 150B extends from the rear end of the housing 110B, and the foreign matter receiving area 160B can be physically distinguished from the laser irradiation device 120B and the collection unit 150B. In addition, the collection unit 150B extends from the rear end of the housing 110B toward the inlet 111B, and the separation distance from the inner surface of the housing 110B is such that the foreign matter receiving area 160B widens toward the inlet 111B. It can gradually increase.

Through this configuration, the foreign matter receiving area 160B can accommodate a larger amount of foreign matter through the inlet 111B and at the same time prevent the foreign matter from flowing into the laser irradiation device 120B or the collection unit 150B.

Figure 8 shows a cross section of a dust removal device (100C) according to another embodiment of the present invention.

The dust removal device 100C may further include a second laser oscillation element 122C compared to the dust removal device 100 described above.

More specifically, the second laser oscillation element 122C may be disposed on the outer surface of the housing 110C adjacent to the foreign matter receiving area 160B.

The second laser oscillation element 122C is disposed to correspond to the irradiation hole 112C formed in the housing 110C, and can irradiate laser through the irradiation hole 112C. Accordingly, the foreign matter contained in the foreign matter receiving area 160C can be miniaturized by removing or cutting it with a laser.

In one embodiment, the laser output from the second laser oscillation device 122C may be different from the laser output from the first laser oscillation device 121C in at least one of wavelength, intensity, and irradiation area. For example, the second laser oscillation element 122C can be used to fragment relatively large-sized foreign substances by emitting a high-intensity laser in a narrower irradiation area. Additionally, the first laser oscillation element 121C has a large irradiation area and can be used to quickly remove flying dust.
