[0002] With the development of industry and urbanization, air pollution is becoming increasingly serious, and due to the various fine dusts generated by vehicles (electric vehicles, etc.) during driving, air pollution is becoming increasingly serious.

[0003] Tire dust generated by the friction between the tires and the road when the vehicle is running, and metal dust generated from the brake discs and brake pads when the vehicle brakes, etc., are factors that further increase the amount of fine dust generated.

[0004] However, since existing vehicles lack fine dust processing technology, air pollution is expected to become more serious. Even in the case of electric vehicles whose sales have increased rapidly recently, a large amount of fine dust is generated in tires and brake devices, so a technology that can effectively collect and process fine dust generated in tires and brake devices, etc. is needed.

[0034] Reference Figures 1 to 11 The vehicle dust collecting device according to the present invention is provided on various vehicles (buses, trucks, coaches, etc.) that use an electric motor or an internal combustion engine as a main power source, and includes a wheel accommodating portion 10, a plurality of suction portions 100, a collecting portion 200, a plurality of collecting lines 300, a driving portion 400 and a control portion 500.

[0035] The wheel housing 10 is formed recessed from both sides of the vehicle body 1 so that the wheels 2 of the vehicle are located inside, and can be divided into a pair of front wheel side wheel housings located in front of the vehicle body 1 and a pair of rear wheel side wheel housings located behind the vehicle body 1. At this time, the front wheel side wheels 2 are rotatably located inside the front wheel side wheel housing 10, and the rear wheel side wheels 2 are rotatably located inside the rear wheel side wheel housing 10.

[0036] The suction part 100 is used to suck in the fine dust B generated inside the wheel receiving part 10. The suction part 100 is respectively arranged on the inner circumferential surface of the wheel receiving part 10. The inlet hole 120 arranged on the front surface of the suction part 100 can be connected with the suction space 110 inside the suction part in a manner of penetrating the front surface of the suction part from front to back, and the discharge hole can penetrate the rear surface of the suction part 100 from front to back so that the fine dust B moving along the suction space 110 can be discharged rearward.

[0037] Here, the suction portion 100 may be eccentrically located behind the vehicle body 1 with respect to the horizontal rotation center of the wheel 2 . However, the suction portion 100 may be located in various ways as required and may have a length that is curved along the rotation direction of the wheel 2 .

[0038] In addition, the front surface of the suction part 100 may be located in the radial direction of the wheel 2, but the position of the suction part 100 may be variously arranged as required. At this time, the front surface of the suction part 100 may be curved in the front-rear direction and concavely formed rearward.

[0039] In addition, the suction portion 100 may be configured to be inserted into the inner peripheral surface of the wheel receiving portion 10, and the front surface of the suction portion 100 may form the same surface as the inner peripheral surface of the wheel receiving portion 10. In this case, since the front surface of the suction portion 100 does not protrude from the inside of the wheel receiving portion 10, the friction resistance with the air A when the vehicle is running can be reduced.

[0040] The suction space 110 is used to move the dust B sucked in through the inlet hole 120 to the collection line 300 described later. It has a length in the front-to-rear direction of the suction part 100, and the dust B moving along the length direction of the suction space 110 moves to the collection line 300 described later through the exhaust hole at the rear.

[0041] The inflow hole 120 is used to introduce the fine dust B into the suction space 110 , and may be arranged in plurality along one or more of the length direction and the width direction of the suction part 100 , and may have a certain diameter to allow the fine dust B to flow in.

[0042] That is, when the suction pressure of the driving unit 400 to be described is applied, the fine dust B sucked through the inflow hole 120 is forced to move along the suction space 110 and then moves to the collecting unit 200 through the collecting line 300 and the driving unit 400 to be described later.

[0043] In addition, a first coupling component 130 for coupling with the front end of the later-described collecting line 300 may be protruded from the rear of the suction part 100. The first coupling component 130 may be formed with a discharge hole formed through the front and rear to discharge the air A, and may have a cylindrical shape with the circumference formed based on the penetration direction of the discharge hole, and a first thread 131 may be formed on the inner or outer circumferential surface of the first coupling component 130 so as to be coupled with the front end of the collecting line 300 inside and outside by thread coupling.

[0044] The suction unit 100 as described above can be respectively provided in a pair of front wheel side wheel receiving parts 10 located in front of the vehicle body 1 and a pair of rear wheel side wheel receiving parts 10 located in the rear of the vehicle body 1, and when the suction force of the driving unit 400 described later is applied, the fine dust B can be respectively sucked into the four wheel receiving parts 10. That is, the fine dust B can be respectively sucked at positions adjacent to the pair of front wheel side wheels 2 and the pair of rear wheel side wheels 2.

[0045] The collecting section 200 is used to accommodate the fine dust B that has passed through the suction section 100, the collecting line 300 and the driving section 400, and can be arranged inside the vehicle body 1, and a accommodating space 210 can be formed inside to accommodate the fine dust B, and the collecting section 200 can be respectively formed with a suction port 220 and an exhaust port 230 to allow air A to flow in and out.

[0046] Here, the collecting portion 200 can be fixedly disposed inside a trunk formed behind the vehicle body 1 and can be exposed to the internal space of the trunk so that the user can confirm and replace it with the naked eye, but the collecting portion 200 can also be disposed in a separate containing structure (not shown) that can be opened and closed.

[0047] In addition, when the collecting part 200 is disposed inside the vehicle body 1 or inside the trunk, the exhaust port 230 may be connected to the outside of the vehicle body 1 through a separate exhaust pipe (not shown). In this case, the inlet of the exhaust pipe is connected to the exhaust port 230, and the outlet of the exhaust pipe may be exposed to the bottom of the vehicle body 1, etc., so as to allow air to be discharged to the outside.

[0048] In addition, the collecting part 200 may include: a first collecting part connected to the right wheel receiving part 10 of the vehicle body 1; and a second collecting part connected to the left wheel receiving part 10 of the vehicle body 1. In this case, the first collecting part and the second collecting part are respectively arranged on both sides of the luggage box so that the fine dust B sucked from the left wheel receiving part and the right wheel receiving part can be separately collected.

[0049] In addition, the collecting part 200 can be made of transparent materials (plastic, etc.) to confirm the existence and capacity of the dust B collected inside, and a corresponding coupling structure (not shown) that can be coupled and separated with the driving part 400 described later can be provided at the front end of the collecting part 200.

[0050] The suction port 220 is used to introduce air A and the dust B included therein, and can be formed on the front surface of the collecting part 200, and when the front end of the suction port 220 is coupled to the driving part 400 described later, the suction port 220 of the collecting part 200 and the exhaust port 230 of the shell 410 described later can be connected in the front-to-back direction.

[0051] The exhaust port 230 is used to exhaust the air A flowing into the accommodating space 210 to the outside, and can be formed at the rear of the collecting portion 200, but the position of the exhaust port 230 can be variously adopted as needed, and a filter portion 240 for filtering the air A can also be provided inside the exhaust port 230.

[0052] The filter unit 240 can selectively use various filters that allow air A to pass through but do not allow dust B to pass through, and its edge is combined with the inner circumferential surface of the exhaust port 230 in a close contact manner. The inner circumferential surface of the exhaust port 230 and the edge of the filter unit 240 can have a corresponding assembly structure so that they can be replaced after a period of use.

[0053] For example, when the driving unit 400 described later is driven, the air A flowing in through the suction port 220 is discharged to the outside after passing through the containing space 210 and the exhaust port 230, and the fine dust B flowing in together with the air A can be collected inside the containing space 210 without passing through the exhaust port 230, and the user can confirm the capacity of the fine dust B collected inside the collecting unit 200 with the naked eye.

[0054] In addition, when the signal output unit 520 described later is lit, the user can immediately recognize the time point when the collection unit 200 needs to be emptied, can confirm the status of the filter unit 240 with the naked eye during the process of emptying the collection unit 200, and can regularly confirm the collection unit 200 and determine whether to replace the filter unit 240 during each set usage cycle.

[0055] A plurality of collecting lines 300 are used to move the air A sucked in from the suction part 100 to the collecting part 200, and may have a pipe shape with a front-to-back length, and a front end may be connected to one side of the suction part 100, and an internal channel 310 of the collecting line 300 running through the length direction is connected to the suction space 110.

[0056] Here, the collecting line 300 may include: 2 right collecting lines 300, connecting the right suction part 100 of the right wheel receiving part 10 of the vehicle body 1 and the first collecting part; and 2 left collecting lines 300, connecting the left suction part 100 of the left wheel receiving part 10 of the vehicle body 1 and the second collecting part.

[0057] In addition, second coupling parts 320 may be respectively provided at the front and rear ends of the collecting line 300 to be threadedly coupled with the first coupling part 130 and the third coupling part 440 described later. The second coupling part 320 has a channel 310 penetrating in the front-to-back direction for the air A to move, and may have a cylindrical shape forming a circumference based on the penetrating direction of the channel 310, and a second thread 321 may be formed on the outer circumferential surface or the inner circumferential surface of the second coupling part 320.

[0058] After the second coupling component 320 in front of the collecting line 300 as described above is configured to correspond to the first coupling component 130 of the suction part 100 in the front-to-back direction, and the second coupling component 320 in the rear is configured to correspond to the third coupling component 440 described later in the front-to-back direction, the collecting line 300 is rotated forward along the coupling direction, so that the second coupling component 320 can be threadedly coupled to the first coupling component 130 and the third coupling component 440, respectively.

[0059] Conversely, the collecting line 300 is reversed in the coupling release direction, so that the second coupling member 320 can be separated from the first coupling member 130 and the third coupling member 440. That is, the collecting line 300 can be easily coupled and separated, so that it is easy to clean, and the coupling and separation process of the collecting line 300 is simple, so it is easy to maintain.

[0060] The driving unit 400 is used to generate suction pressure, and is connected to the rear end of the collecting line 300 and the suction port 100 of the collecting unit 200. When the driving unit 400 is driven, it forces the air A transmitted from the channel to move to the suction port by generating suction, and the driving unit 400 can be driven by the control unit 500 described later.

[0061] Here, the driving part 400 may include: a shell 410, which forms an inflow space 411 inside and is connected to the front end of the collecting part 200 at the rear end; a plurality of first connecting holes 412, which are vertically formed through the lower end of the shell 410 and are respectively connected to the rear ends of the collecting line 300; a second connecting hole 413, which is formed through the rear end of the shell 410 from front to back and is connected to the suction port 220 of the collecting part 200 from front to back; a rotating motor 420, which is fixedly arranged in the inflow space 411 and driven by the control part 500 described later; and an exhaust fan 430, which is rotatably connected to the driving shaft of the rotating motor 420 and moves the air A flowing into the inflow space 411 through the second connecting hole 413 and the suction port 220 and then moves to the interior of the accommodating space 210 when rotating.

[0062] The housing 410 may be fixedly disposed inside the vehicle body 1 or inside the trunk of the vehicle body 1, and the rear end of the housing 410 may be provided with a corresponding coupling structure (not shown) that can be coupled and separated with the front end of the collecting unit 200. For example, the rear end of the housing 410 and the front end of the collecting unit 200 may be coupled and separated by a threaded coupling, and when a certain volume (95%, etc.) of fine dust fills the accommodation space 210 of the collecting unit 200, the fine dust B may be discharged to the outside or cleaned by separating the collecting unit 200 from the housing 410.

[0063] like Figure 3 and Figure 4 The rotary motor 420 is fixedly disposed inside the inflow space 411, and the drive shaft protruding rearward may be disposed horizontally toward the penetration direction of the second communication hole 413, and may be electrically connected to the control unit 500 described later and driven by the battery 3 of the vehicle. When applied to an electric vehicle, the high-capacity battery 3 disposed inside the vehicle body 1 may be used as the driving power of the rotary motor 420.

[0064] The exhaust fan 430 is located at the inflow side of the second connecting hole 413, and the horizontal rotation center of the exhaust fan 430 can be combined with the driving shaft of the rotating motor 420 on the same axis, and a plurality of rotating blades are arranged radially with the horizontal rotation center of the exhaust fan 430 as a reference. When the exhaust fan 430 as described above rotates together with the driving shaft of the rotating motor 420, the internal air A flowing into the space 411 is forced to pass through the second connecting hole 413 and the suction port 220 and move to the inside of the accommodating space 210.

[0065] In addition, a plurality of third coupling parts 440 may be respectively provided at the lower end of the housing 410 to be threadedly coupled with the second coupling parts 320 of the collecting line 300, and a channel may be formed through the third coupling parts 440 in the front-rear direction so that the air A can move. Here, the third coupling parts 440 may have a cylindrical shape with a circumference formed based on the through direction of the channel, and a third thread 441 may be formed on the outer circumferential surface or the inner circumferential surface of the third coupling parts 440.

[0066] In addition, the rear end of the third combining component 440 and the first connecting hole 412 can be connected by a connecting pipe, and the two sides of the connecting pipe in the length direction can be respectively connected to the rear end of the third combining component 440 and the first connecting hole 412, and the interior of the connecting pipe can be penetrated along the front-to-back direction to form a channel so that air A can move.

[0067] For example, after the second combining component 320 of the collecting line 300 is configured to correspond to the front end of the third combining component 440, the collecting line 300 is rotated forward along the combining direction so that the second combining component 320 and the third combining component 440 can be threadedly combined, and since the internal channel 310 of the second combining component 320 and the internal channel of the third combining component 440 are connected to each other, the dust B moving toward the rear of the collecting line 300 can flow into the space 411 and move to the accommodating space 210.

[0068] The control unit 500 is used to control the driving of the driving unit 400. The control unit 500 can switch the driving unit 400 to a driving on (ON) state when the vehicle is started on, and can switch the driving unit 400 to a driving off (OFF) state when the vehicle is started off, and can also switch the driving unit 400 to a driving on (ON) / off (OFF) state through manual operation of the user.

[0069] In addition, the control unit 500 may be electrically connected to an operating unit (not shown) so that a user can manually turn on / off the driving of the driving unit 400. The operating unit may be operably disposed in the interior of the vehicle (instrument panel, door, etc.), and may be provided with an operating switch for selecting various functions and an information display unit (not shown) for externally displaying the operating state of the driving unit 400.

[0070] For example, when the driving shaft of the rotating motor 420 rotates according to the driving control of the control unit 500, the exhaust fan 430 rotates and generates suction pressure, and the air A flowing in through the inlet hole 120 of the suction part 100 passes through the suction space 110 and the collecting line 300 and flows into the inlet space 411 of the shell 410.

[0071] After the air A flowing into the inflow space 411 moves to the storage space 210 of the collection unit 200, it passes through the discharge port 230 and is discharged to the outside of the housing 410, and the fine dust B sucked in together with the air A is collected inside the storage space 210. At this time, the filter unit 240 provided at the discharge port 230 only discharges the air A to the outside, so the fine dust B collected in the storage space 210 is not discharged to the outside of the housing 410.

[0072] According to an embodiment of the present invention, the dust collecting device for a vehicle may further include: a collection amount detecting unit 510, which is combined with the collecting unit 200, and when the dust B collected in the containing space 210 fills up to a set amount or more, a notification signal is transmitted to the control unit 500; and a signal output unit 520, which is arranged in the state of the vehicle body 1 and is electrically connected to the control unit 500, and when the notification signal is transmitted to the control unit 500, it is illuminated and diffuses the light to the outside.

[0073] The collection amount detection unit 510 can be electrically connected to the control unit 500 when fixedly coupled to the collection unit 200. The detection side on one side can detect the collection amount of the fine dust B inside the containing space 210, and can detect the collection amount of the fine dust B based on the height of the fine dust B collected in the containing space 210, the pressure of the containing space 210, etc.

[0074] Here, the collection amount detection unit 510 can selectively use various sensors that can measure the collection amount of fine dust B, and can use a differential pressure sensor, a pressure sensor, an infrared ray sensor, etc., but various sensors can be selectively used as needed.

[0075] For example, when a differential pressure sensor or a pressure sensor is used as the collection amount detection unit 510, the internal pressure change of the containing space 210 can be detected, and when the dust B fills all the containing space 210, the pressure increase in the containing space 210 can be detected due to the blockage of the exhaust port 230 of the collecting unit 200, and the control unit 500 can diffuse the light to the outside by lighting up the signal output unit 520.

[0076] On the other hand, when an infrared sensor is used as the collection amount detection unit 510, the height of the dust B contained in the bottom surface of the containing space 210 can be detected, and when the dust B reaches the set height, the collection amount detection unit 510 can transmit the detection signal to the control unit 500 after detecting the dust B, and the control unit 500 can diffuse the light to the outside by lighting up the signal output unit 520.

[0077] The signal output unit 520 may be provided on the interior side of the vehicle (instrument panel, door, etc.), and when the notification signal is transmitted to the control unit 500, the signal output unit 520 is illuminated and diffuses red (Red), green (Green), etc. light to the interior side of the vehicle. That is, the vehicle occupants can easily confirm the light (red, etc.) diffused from the signal output unit 520 with the naked eye, and thus can immediately recognize the time point when the collection unit 200 needs to be emptied.

[0078] In addition, the dust collection device for a vehicle may also include a speed detection unit 530, which is electrically connected to the control unit 500 and detects the moving speed of the vehicle body 1, wherein the control unit 500 has a preset reference speed and can change the suction force of the driving unit 400 so that the suction force is proportional to the moving speed transmitted from the speed detection unit 530.

[0079] The speed detection unit 530 may use a speed sensor, and may use a speed measuring tool provided in the vehicle to detect the moving speed of the vehicle. For example, when the vehicle travels at a speed of 10 km, the drive shaft of the rotary motor 420 may be rotated at a first speed, and when the vehicle travels at a speed of 20 km, the drive shaft of the rotary motor 420 may be rotated at a second speed, thereby increasing the suction pressure.

[0080] That is, as the moving speed of the vehicle increases, the amount of fine dust B generated increases due to the wear of the brake pads and the wheels 2, etc., so a large amount of fine dust B can be absorbed at high pressure by increasing the rotation speed of the rotating motor 420, and as the moving speed of the vehicle decreases, the amount of fine dust B generated decreases, so the power usage and noise can be reduced by reducing the rotation speed of the rotating motor 420.

[0081] like Fig. 9 and Fig.10 As shown, the dust collecting device for a vehicle according to an embodiment of the present invention may further include an auxiliary suction part 600. The auxiliary suction part 600 extends horizontally from one side of the width direction of the suction part 100, and then bends and extends downward, so that the lower end of the auxiliary suction part 600 between the vehicle body 1 and the suction part 100 can be close to the horizontal rotation center position of the wheel 2. If necessary, the auxiliary suction part 600 can be vertically arranged on one side of the axial direction of the wheel 2 on the opposite side of the vehicle body 1, so that the auxiliary suction part 600 is exposed to the outside of the vehicle body 10, and the auxiliary suction part 600 can also be arranged between the vehicle body 1 and the suction part 100 and on one side of the axial direction of the wheel 2 on the opposite side of the vehicle body 1.

[0082] Here, an auxiliary suction space 610 is formed inside the auxiliary suction part 600, and the top of the auxiliary suction space 610 can be connected to one side of the suction space 110 in the width direction to allow air A to circulate, and an auxiliary inflow hole 620 is formed on one side of the auxiliary suction part 600 to allow air A to be sucked into the auxiliary suction space 610.

[0083] The auxiliary inflow hole 620 may be formed on one side of the auxiliary suction part 600 facing the wheel 2, and may penetrate the left and right sides of the auxiliary suction part 600 so that the fine dust B generated inside the wheel receiving part 10 moves to the auxiliary suction space 610. Here, the auxiliary inflow hole 620 may be arranged in a plurality of spaces along one or more directions of the up-down direction and the front-back direction of the auxiliary suction part 600, and may have a certain diameter to allow the fine dust B to flow in.

[0084] For example, when the suction pressure of the driving part 400 is applied, the fine dust B sucked through the auxiliary inflow hole 620 can be forced to pass through the auxiliary suction space 610 and move to the suction space 110, and the fine dust B moved to the suction space 110 passes through the collecting line 300 and the driving part 400 and moves to the collecting part 200.

[0085] That is, since air A flows in through the inlet hole 120 located in the radial direction of the wheel 2 and the auxiliary inlet hole 620 located in the axial direction of the wheel 2, the amount of fine dust B sucked in can be increased, and the auxiliary suction part 600 can suck in the fine dust B at a position close to the rotation center of the wheel 2 (such as the brake pad setting position), thereby improving the collection performance.

[0086] like Fig.11 As shown, the dust collecting device for a vehicle according to an embodiment of the present invention may further include a vibration generating unit 700 for transmitting vibration to the suction unit 100. The vibration generating unit 700 may include: a vibration motor 710 coupled to one side of the suction unit 100, and the driving of the vibration motor 710 is controlled by the control unit 500; and a counterweight 720 eccentrically rotatably coupled to a driving shaft of the vibration motor 710 and generating vibration by eccentric rotation.

[0087] In addition, a separate box may be combined on one side of the suction part 100, a vibration motor 710 may be fixedly installed inside the box, and the vibration motor 710 may be periodically operated by presetting the driving time of the vibration motor 710 in the control part 500, or the vibration motor 710 may be manually driven using the operating part of the control part 500.

[0088] One side of the counterweight 720 can be eccentrically rotatably coupled to the front end of the drive shaft, and the counterweight 720 can be made of a material such as metal to generate vibration, and the vibration generation intensity can be adjusted in various ways by setting the rotation speed of the drive shaft of the vibration motor 710 differently, and since the vibration motor 710 is fixed to the suction part 100, the vibration generated when the counterweight 720 rotates can be transmitted to the suction part 100. Since the eccentric side of the counterweight 720 rotates with a larger rotation radius by centrifugal force when the drive shaft rotates, the counterweight 720 as described above can transmit the vibration to the drive shaft of the vibration motor 710.

[0089] That is, by utilizing the vibration generated when the counterweight 720 rotates eccentrically, the dust B attached to the inner surface of the suction space 110 can be separated by vibration, thereby preventing the suction space 110 from being blocked. Moreover, since the cross-sectional area of ​​the suction space 110 will not be reduced due to the attachment of the dust B, the operating function of the device can be maintained in the optimal state.

[0090] As a result, the present invention can collect various fine dusts B generated by the wheel accommodating portion 10 when the vehicle is running, thereby minimizing environmental pollution, and can suck in the fine dust B with a suction force proportional to the driving speed of the vehicle, thereby maintaining a certain collection function, and can easily separate the fine dust collection line 300, thereby facilitating maintenance.

[0091] As mentioned above, the detailed embodiment of the vehicle dust collecting device of the present invention has been described, but it is obvious that various modifications may be made without departing from the scope of the present invention.

[0092] Thus, the scope of the present invention should not be limited to the described embodiments, but should be determined by the following claims and their equivalents.

[0093] That is, the above-mentioned embodiments should be understood in all aspects as illustrative rather than restrictive, and the scope of the present invention is indicated by the claims rather than the detailed description, and the meaning, scope of the claims and all changes or modifications derived from equivalent concepts should be interpreted as being included in the scope of the present invention.
