Description

Caliper-type particle dust collector

[0001] Embodiments of the present invention relate to a caliper-type particle dust collector.

[0002] It is generally known that fine dust generated during vehicle operation is produced in large quantities by tire and brake pad wear in addition to exhaust gases; therefore, to reduce urban fine dust, it is required to reduce fine dust generated by automobiles, which is one of the primary causes of mobile pollution.

[0003] Specifically, the vehicle's braking system generates braking force through the frictional force produced by pressing brake pads against a brake disc that rotates together with the vehicle's wheels; however, during vehicle braking, the wear of the brake pads caused by friction between the brake disc and the brake pads generates various types of dust harmful to the human body.

[0004] Fine dust generated by brake pad wear is known to have harmful effects on the human body, including respiratory, eye, and skin diseases, due to its very small size and toxic composition. Therefore, the development of technology to address this issue is required.

[0005] While the impact of fine dust generation from exhaust gases is expected to gradually decrease due to the recent increase in hydrogen and electric vehicles, fine dust generation caused by tire and brake pad wear still occurs because these vehicles utilize braking systems similar to internal combustion engine vehicles.

[0006] Devices installed around automobile wheels to capture fine dust generated by tire and brake pad wear have been developed, and most of them use a filter method.

[0007] However, in the case of filter-type air purifiers, pressure loss caused by the filter makes it difficult for air containing particles to enter, resulting in practical difficulties in capturing fine dust after a certain period of time. Additionally, fiber filters have limitations in maintenance, such as the difficulty of cleaning and regenerating them, which necessitates frequent replacement.

[0008] The aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot be considered as prior art disclosed to the general public prior to the filing of the present invention.

[0052] FIG. 1 is a schematic diagram illustrating a caliper-type particle dust collector according to an embodiment of the present invention. FIG. 2 is a diagram illustrating a first dust collection unit according to an embodiment of the present invention. FIG. 3 is a diagram for explaining the positions of the first dust collection unit and the second dust collection unit disposed on a brake disc.

[0054] FIG. 6 is a diagram illustrating a state in which a guide part according to an embodiment of the present invention is positioned at a second location. FIG. 7 is a block diagram for explaining the usage state of a control part according to an embodiment of the present invention.

[0055] A caliper-type particle dust collector (1) according to one embodiment of the present invention relates to a device for collecting particles (P) generated by friction between a brake disc (BD) and a brake pad (not shown in the drawing) of a caliper part (100) during braking in a vehicle that performs braking including a brake disc (BD) and a caliper part (100).

[0056] Referring to FIGS. 1 to 4, a caliper-type particle dust collector (1) (hereinafter referred to as the 'particle dust collector (1)') according to one embodiment of the present invention may include a brake disc (BD), a caliper part (100), a first dust collection part (200), a second dust collection part (300), a guide part (500), a driving part (600), a control part (700), and a sensor part (800).

[0057] The brake disc (BD) is connected to rotate in conjunction with the wheel of the vehicle. For example, when the wheel rotates, the brake disc (BD) can rotate integrally with the wheel.

[0058] The caliper part (100) can apply braking force to a brake disc (BD) that rotates integrally with the wheel, and when braking force is applied to the brake disc (BD), the rotational speed of the wheel that rotates integrally with the brake disc (BD) is reduced.

[0059] The brake disc (BD) can form a braking system of the vehicle together with the caliper part (100).

[0060] The caliper part (100) includes a brake pad that moves by operation of a user, and depending on the operation of the user, the brake pad can selectively contact the brake disc (BD) to provide frictional force, thereby applying braking force to the brake disc (BD) or the wheel.

[0061] Referring to FIGS. 1, 3 to 6, a caliper portion (100) according to one embodiment of the present invention is positioned on one side in the circumferential direction of a brake disc (BD), and a user can apply braking force to the brake disc (BD) by using a brake pedal or the like to press a brake pad against the brake disc (BD).

[0062] Referring to FIG. 1, a caliper part (100) according to one embodiment of the present invention may be positioned on the front side of a vehicle.

[0063] However, it is not limited to this, and the caliper part (100) can be positioned in various locations within the technical concept of being able to apply braking force to the brake disc (BD) on the brake disc (BD).

[0064] Since the brake disc (BD) and caliper part (100) are applied in various structures to conventional vehicle braking systems, a detailed description of the internal configuration and operating principle of the brake disc (BD) and caliper part (100) is omitted.

[0065] Referring to FIG. 1 and FIG. 2, a first dust collection unit (200) according to one embodiment of the present invention electrostatically collects particles (P) generated by friction between a brake disc (BD) and a caliper unit (100), and may include a first dust collection plate (210), a second dust collection plate (220), a high voltage application unit (230), and a first cover unit (240).

[0066] Particles (P) generated from the brake pad are charged by friction between the brake pad and the brake disc (BD), and accordingly, the particle dust collector (1) according to one embodiment of the present invention does not need to be equipped with a separate charging device for electrostatic dust collection.

[0067] A first dust collection unit (200) is positioned at the rear of the caliper unit (100) from which charged particles (P) are discharged, and the first dust collection unit (200) can collect the charged particles (P) by the force of an electric field.

[0068] Since particles (P) generated from the brake pad are discharged from the caliper part (100) in the direction of rotation of the brake disc (BD), the caliper-type particle dust collector (1) can easily collect particles (P) by placing a first dust collection part (200) on one side of the caliper part (100) without a separate air flow device such as a fan.

[0069] The first dust collection unit (200) may be spaced apart from the caliper unit (100), and specifically, the caliper unit (100) and the first dust collection unit (200) may be spaced apart in the circumferential direction of the brake disc (BD).

[0070] In an optional embodiment, a plurality of first dust collection units (200) may be provided, and the plurality of first dust collection units (200) may be arranged adjacent to each end of the caliper unit (100).

[0071] Referring to FIG. 2, the first dust collection plate (210) can receive high voltage from the high voltage application unit (230). Additionally, the second dust collection plate (220) can be grounded at a distance from the first dust collection plate (210).

[0072] The first dust collection plate (210) and the second dust collection plate (220) can be spaced apart and placed parallel to each other along the thickness direction of the brake disc (BD).

[0073] Referring to FIG. 2, a plurality of first dust collection plates (210) and second dust collection plates (220) may each be provided, and the plurality of first dust collection plates (210) and second dust collection plates (220) may be spaced apart to repeat each other along the thickness direction of the brake disc (BD).

[0074] For example, one second dust collection plate (220) may be placed between two first dust collection plates (210), and one first dust collection plate (210) may be placed between two second dust collection plates (220).

[0075] One side of the first dust collection plate (210) and one side of the second dust collection plate (220) may be parallel to the surface of the brake disc (BD).

[0076] As a result, the surface of the brake disc (BD) and the first dust collection plate (210) to the second dust collection plate (220) face each other in parallel, thereby securing a large surface area where particles (P) discharged from the surface of the brake disc (BD) can be attached to the first dust collection plate (210) to the second dust collection plate (220), and thereby the electrostatic collection of particles (P) can be effectively performed.

[0077] The charged particles (P) generated between the brake disc (BD) and the caliper part (100) move toward the first dust collection part (200) along the direction of rotation of the brake disc (BD), and the charged particles (P) can move into the space between the first dust collection plate (210) and the second dust collection plate (220).

[0078] Since the first dust collection plate (210) is subjected to high voltage and the second dust collection plate (220) is grounded, an electric field is formed in the separation space due to the potential difference between the first dust collection plate (210) and the second dust collection plate (220), and charged particles (P) moving into the separation space can be collected in the first dust collection unit (200) by the electric field.

[0079] In an optional embodiment, a filter may be separately provided between the first dust collection plate (210) and the second dust collection plate (220), thereby allowing for effective collection of particles (P) along with dust collection of particles (P) by an electric field.

[0080] Referring to FIGS. 1, FIGS. 2, FIGS. 4 to 6, a high voltage application unit (230) according to one embodiment of the present invention can receive an electrical signal from a control unit (700) and adjust the magnitude of the voltage applied to the first dust collection plate (210).

[0081] The control unit (700) receives information regarding the speed of the vehicle or the rotational speed of the brake disc (BD) and can control the magnitude of the voltage provided by the high voltage application unit (230) to the first dust collection plate (210).

[0082] For example, if the speed of the vehicle or the rotational speed of the brake disc (BD) is greater than a preset value, the high voltage application unit (230) can reduce the magnitude of the voltage provided to the first dust collection plate (210).

[0083] In addition, if the speed of the vehicle or the rotational speed of the brake disc (BD) is lower than a preset value, the high voltage application unit (230) can increase the magnitude of the voltage provided to the first dust collection plate (210).

[0084] When the vehicle speed is high, the charge amount of the particles (P) is high due to strong friction between the brake disc (BD) and the caliper part (100), so even if a relatively weak high voltage is applied to the first dust collection plate (210) by the high voltage application part (230) according to the control signal of the control part (700), the particles (P) with a high charge amount can be easily collected by only the weak electric field generated in the first dust collection part (200).

[0085] When the vehicle speed is low, even if the charge amount of the particle (P) is not high due to relatively little friction between the brake disc (BD) and the caliper part (100), the high voltage application part (230) can apply a relatively strong high voltage to the first dust collection plate (210) according to the control signal of the control part (700) to easily collect particles (P) with a low charge amount.

[0086] As a result, it is possible to appropriately adjust the magnitude of the voltage applied to the first dust collection plate (210) by the high voltage application unit (230) according to the charge amount of the particle (P), so that the power consumption of the first dust collection unit (200) is minimized and the dust collection performance of the first dust collection unit (200) can be increased.

[0087] Referring to FIGS. 1, 4 to 6, a first cover portion (240) according to one embodiment of the present invention can accommodate a first dust collection plate (210) and a second dust collection plate (220) inside and can be formed to extend along the circumferential direction of a brake disc (BD).

[0088] The length of the first cover portion (240) extending along the circumferential direction of the brake disc (BD) can be formed to be relatively longer than the length of the first dust collection plate (210) and the second dust collection plate (220) extending along the circumferential direction of the brake disc (BD).

[0089] As a result, the first cover portion (240) separates the first dust collection plate (210) and the second dust collection plate (220) from the external space, thereby preventing the phenomenon of particles (P) moving to the space where the first dust collection plate (210) and the second dust collection plate (220) are located from moving away from the first dust collection plate (210) and the second dust collection plate (220) due to external factors such as wind (W).

[0090] According to one embodiment of the present invention, the first cover portion (240) may be spaced apart from the caliper portion (100).

[0091] For example, one end of the first cover part (240) facing the caliper part (100) and the other end of the caliper part (100) facing the first cover part (240) may be spaced apart from each other by a predetermined distance, and a second dust collection part (300) may be placed between the first cover part (240) and the caliper part (100).

[0092] As a result, the brake disc (BD) can be exposed to the outside through the gap between the caliper part (100) and the first cover part (240), so that the brake disc (BD) is exposed to the outside immediately after friction with the caliper part (100), thereby allowing the brake disc (BD) to be easily cooled.

[0093] According to one embodiment of the present invention, the first cover portion (240) can be fixed in position on the brake disc (BD).

[0094] For example, the first cover portion (240) may be fixedly connected to at least one of the brake disc (BD), caliper portion (100), first dust collection plate (210), or second dust collection plate (220).

[0095] As a result, the first cover portion (240) stably covers the first dust collection plate (210) and the second dust collection plate (220), thereby guiding particles (P) entering the interior of the first cover portion (240) to flow stably into the space between the first dust collection plate (210) and the second dust collection plate (220).

[0096] Referring to FIGS. 1, 4 to 6, a first cover portion (240) according to one embodiment of the present invention can accommodate a first dust collection plate (210) and a second dust collection plate (220) inside and can be connected to a second dust collection portion (300).

[0097] For example, the first cover portion (240) can be connected to the second cover portion (320) of the second dust collection portion (300), and specifically, one end of the first cover portion (240) can be fixed in position at one end of the second cover portion (320).

[0098] The first cover portion (240) and the second cover portion (320) may be spaced apart by a predetermined interval along the circumferential direction of the brake disc (BD). Air may be introduced between the first cover portion (240) and the second cover portion (320) to effectively cool the brake disc (BD) located inside the first cover portion (240) and the second cover portion (320).

[0099] However, it is not limited thereto, and the first cover part (240) can accommodate the first dust collection plate (210), the second dust collection plate (220), as well as the magnet part (310) on the inside, and in this case, the first cover part (240) and the second cover part (320) can be formed integrally.

[0100] For example, the first dust collection plate (210), the second dust collection plate (220), and the magnet part (310) can all be fixed in position on the inner side of the first cover part (240), and specifically, the magnet part (310) can be positioned between the caliper part (100) and the first dust collection plate (210) on the inner area of ​​the first cover part (240).

[0101] Various sizes of dust particles (P) may be generated in the brake disc (BD). Among the particles (P) generated in the brake disc (BD), particles (P) that are small in size or mass may have a relatively small inertial force applied to them (P) and may be rapidly charged due to friction with the brake pad, etc.

[0102] Accordingly, most of the particles (P) with small size or mass can be discharged from the caliper part (100) and move circumferentially along the brake disc (BD), and through this, most of the particles (P) with small size or mass can move to the first dust collection part (200) and be collected by the electric field of the first dust collection part (200).

[0103] However, unlike this, in the case of particles (P) that are relatively large in size or mass among the particles (P) generated from the brake disc (BD), a large inertial force may act on the particles (P).

[0104] In this case, most of the particles (P) discharged from the caliper part (100) can move in the radial direction of the brake disc (BD) by centrifugal force or inertial force, and through this, most of the particles (P) with large size or mass are discharged to the outside of the brake disc (BD) before moving to the first dust collection part (200), thereby reducing the collection efficiency of the particle dust collection device (1).

[0105] A particle dust collector (1) according to one embodiment of the present invention is provided with a second dust collector (300) that collects particles (P) between the first dust collector (200) and the caliper (100), thereby effectively collecting particles (P) that are about to be discharged to the outside between the first dust collector (200) and the caliper (100).

[0106] FIG. 8 is a graph showing the ratio of particles that can be collected in the first dust collection unit (200) and particles that can be collected in the second dust collection unit (300) according to particle size.

[0107] Specifically, FIG. 8 is an experimental result regarding the trend of the ratio of particles that can be collected in the first dust collection unit (200) and particles that can be collected in the second dust collection unit (300) according to the size of the particles (P).

[0108] Referring to FIG. 8, experimental results show that when the size of the particle (P) is greater than 0.5 μm and less than or equal to 1.0 μm, approximately 83% of the total particles (P) can be collected in the first dust collector (200) that collects the particles (P) with an electric field, and approximately 18% of the total particles (P) can be collected in the second dust collector (300) that collects the particles (P) with a magnetic field.

[0109] In addition, when the size of the particle (P) is greater than 1.0 μm and less than or equal to 2.5 μm, approximately 84% of the total particles (P) can be collected in the first dust collection unit (200) which collects the particles (P) with an electric field, and approximately 44% of the total particles (P) can be collected in the second dust collection unit (300) which collects the particles (P) with a magnetic field.

[0110] In addition, when the size of the particles (P) is greater than 2.5 μm and less than or equal to 5.0 μm, approximately 80% of the total particles (P) can be collected in the first dust collection unit (200) which collects the particles (P) with an electric field, and approximately 78% of the total particles (P) can be collected in the second dust collection unit (300) which collects the particles (P) with a magnetic field.

[0111] Additionally, when the size of the particle (P) exceeds 5.0 μm, approximately 68% of the total particles (P) can be collected in the first dust collection unit (200) that collects the particles (P) with an electric field, and approximately 98% of the total particles (P) can be collected in the second dust collection unit (300) that collects the particles (P) with a magnetic field.

[0112] According to the experimental results described above, it can be seen that the larger the size of the particle (P), the more advantageous the dust collection method using a magnetic field or magnetic force is.

[0113] According to one embodiment of the present invention, the second dust collection unit (300) is designed as a magnetic dust collection device that is advantageous for collecting relatively large particles (P) rather than an electrostatic dust collection method that is advantageous for collecting small particles (P) based on the experimental results described above, and accordingly, the second dust collection unit (300) can effectively collect particles (P) that are about to be discharged to the outside by centrifugal force or inertial force between the first dust collection unit (200) and the caliper unit (100).

[0114] Referring to FIGS. 1, 3 to 6, a second dust collection unit (300) according to one embodiment of the present invention collects dust particles (P) with a magnetic field and may include a magnet unit (310) and a second cover unit (320).

[0115] Referring to FIGS. 1 and 3, the second dust collector (300) can be positioned between the first dust collector (200) and the caliper part (100).

[0116] The second dust collection unit (300) may be positioned on the outer periphery of the brake disc (BD). For example, the second dust collection unit (300) may be positioned to face the other outer side of the brake disc (BD) that is in contact with the brake pad.

[0117] Referring to FIGS. 1 and 3, the magnet portion (310) forms a magnetic field around the outer periphery of the brake disc (BD) and can be placed on the outer circumference of the brake disc (BD).

[0118] The magnet part (310) may be made of a magnetic material, for example, the magnet part (310) may be made of a permanent magnet or an electromagnet.

[0119] The magnet portion (310) can be positioned between the first dust collection portion (200) and the caliper portion (100), and specifically, it can be positioned on the outer circumference of the brake disc (BD) located in the space between the first dust collection portion (200) and the caliper portion (100).

[0120] Referring to FIG. 3, the magnet part (310) can be placed on a preset reference axis (CL).

[0121] In this specification, 'reference axis (CL)' can be interpreted as the longitudinal center axis of the brake pad provided in the caliper portion (100).

[0122] For example, the 'reference axis (CL)' may be an axis that extends along the longitudinal direction of the brake pad, passing through the center of the area where the brake pad and the brake disc (BD) come into contact.

[0123] Referring to FIG. 3, the magnet portion (310) can be placed on the area where the reference axis (CL) and the outer edge of the brake disc (BD) intersect.

[0124] As a result, the magnet part (310) is positioned on the path of particles (P) moving outward between the first and second dust collection plates (210, 220) and the caliper part (100), so that the magnet part (310) can easily capture particles (P) moving in the radial direction of the brake disc (BD) between the first and second dust collection plates (210, 220) and the caliper part (100) with a magnetic field.

[0125] Referring to FIGS. 1, 4 to 6, a second cover portion (320) according to one embodiment of the present invention may be positioned between the first dust collection portion (200) and the caliper portion (100), and may be positioned spaced apart from the caliper portion (100).

[0126] For example, one end of the second cover part (320) facing the caliper part (100) and the other end of the caliper part (100) facing the second cover part (320) may be spaced apart from each other by a predetermined distance.

[0127] As a result, the brake disc (BD) can be exposed to the outside through the gap between the caliper part (100) and the first cover part (240), so that the brake disc (BD) is exposed to the outside immediately after friction with the caliper part (100), thereby allowing the brake disc (BD) to be easily cooled.

[0128] The second cover portion (320) can be fixed in position on the first cover portion (240), and for example, the second cover portion (320) and the first cover portion (240) can be formed integrally.

[0129] As a result, particles (P) that are not captured by the magnet part (310) placed inside the second cover part (320) are not released to the outside by the first cover part (240) or the second cover part (320), and can be stably moved to the first dust collection plate (210) or the second dust collection plate (220).

[0130] Referring to FIGS. 4 to 7, a guide section (500) according to one embodiment of the present invention provides a movement path for a particle (P) and can selectively cover the space between the caliper section (100) and the first dust collection section (200).

[0131] In the following specification, 'first position' can be interpreted as the position of a guide part (500) arranged to cover the space between the caliper part (100) and the second dust collection part (300), and 'second position' can be interpreted as the position of a guide part (500) arranged to expose the space between the caliper part (100) and the second dust collection part (300) to the outside.

[0132] However, it is not limited thereto, and the ‘first position’ can be interpreted as the position of a guide part (500) positioned to cover a preset area of ​​the caliper part (100), and the ‘second position’ can be interpreted as the position of a guide part (500) positioned to cover an area relatively narrower than the said area of ​​the caliper part (100).

[0133] For example, when the guide portion (500) moves to a first position, the guide portion (500) can cover more than half of the outer surface of the caliper portion (100), and when the guide portion (500) moves to a second position, the guide portion (500) can cover less than half of the outer surface of the caliper portion (100).

[0134] Referring to FIGS. 4 to 7, the guide portion (500) may be movable along the circumferential direction of the brake disc (BD).

[0135] In one embodiment, the guide unit (500) receives an electrical signal from the control unit (700) and can move along the circumferential direction of the brake disc (BD).

[0136] Specifically, the guide section (500) can move along the circumferential direction of the brake disc (BD) by receiving power from the driving section (600), and the driving section (600) can adjust the position of the guide section (500) by receiving an electrical signal from the control section (700).

[0137] Referring to FIG. 3, the guide portion (500) can selectively accommodate the caliper portion (100) according to the electrical signal of the control portion (700).

[0138] The width of the brake disc (BD) in the thickness direction of the guide section (500) may be relatively larger than the width of the brake disc (BD) in the thickness direction of the caliper section (100) and the width of the brake disc (BD) in the thickness direction of the first dust collection section (200).

[0139] Additionally, the width of the brake disc (BD) of the guide section (500) in the thickness direction may be relatively larger than the width of the brake disc (BD) of the second dust collection section (300) in the thickness direction.

[0140] Referring to FIG. 5, the guide portion (500) can move along the circumferential direction of the brake disc (BD), and when the guide portion (500) is positioned at the first position, the guide portion (500) can cover the outer surface of the caliper portion (100) and the space between the caliper portion (100) and the second dust collection portion (300).

[0141] Referring to FIG. 6, when the guide portion (500) is positioned at a second location, the guide portion (500) can cover the outer surface of the first dust collection portion (200) and the outer surface of the second dust collection portion (300), and at the same time, the guide portion (500) can expose the space between the caliper portion (100) and the second dust collection portion (300) to the outside.

[0142] Referring to FIG. 5, the guide portion (500) receives power from the driving portion (600) and moves to a first position to cover the outer surface of the caliper portion (100).

[0143] As a result, the guide section (500) partitions the caliper section (100) from the external space, thereby restricting the inflow of wind (W) directed toward the caliper section (100) into the caliper section (100) due to vehicle driving, etc., and thereby the movement path of the particles (P) generated inside the caliper section (100) can be guided so that they flow toward the first dust collection section (200) without being affected by wind (W), etc.

[0144] Referring to FIG. 6, the guide portion (500) receives power from the driving portion (600) and moves to a second position, thereby allowing the caliper portion (100) to be exposed to the outside.

[0145] As a result, the wind (W) flows into the internal space of the caliper part (100) or into the space between the caliper part (100) and the first dust collection part (200), thereby increasing the contact area between the wind (W) and the brake disc (BD), which has the effect of increasing the cooling efficiency of the brake disc (BD).

[0146] In an optional embodiment, a plurality of guide sections (500) may be provided, and each of the plurality of guide sections (500) may receive power from a driving section (600) and move independently along the circumferential direction of the brake disc (BD).

[0147] The position of the guide part (500) can be adjusted according to the rotational speed of the brake disc (BD), the temperature of the brake disc (BD), the amount of particles (P) generated, or the amount of charge of the particles (P), and a detailed explanation related thereto will be provided later.

[0148] The guide portion (500) can be movably connected to one side of the first cover portion (240) or the second cover portion (320).

[0149] As a result, the guide portion (500) moves relative to the first cover portion (240) and the second cover portion (320) fixed to the brake disc (BD), thereby allowing the caliper portion (100) to be selectively covered or exposed to the outside.

[0150] In an optional embodiment, the guide portion (500) may be movably connected to one side of the caliper portion (100). As a result, the guide portion (500) moves relative to the caliper portion (100) which is fixed to the brake disc (BD), thereby allowing the caliper portion (100) to be selectively covered or exposed to the outside.

[0151] In an optional embodiment, the guide portion (500) may be movably connected to one side of the brake disc (BD). As a result, the guide portion (500) moves relative to the brake disc (BD), thereby allowing the caliper portion (100) fixed to the brake disc (BD) to be selectively covered or exposed to the outside.

[0152] Referring to FIGS. 1 and 3, the guide portion (500) may be arranged to surround one end of the second cover portion (320) facing the caliper portion (100).

[0153] Specifically, the guide portion (500) may be arranged to surround one end of the second cover portion (320) facing the caliper portion (100) and one end of the caliper portion (100) facing the second cover portion (320), respectively.

[0154] As a result, the guide part (500) covers the space between the upper end of the second cover part (320) and the upper end of the caliper part (100), thereby preventing the particle (P) generated in the caliper part (100) from escaping to the outside during the process of moving toward the magnet part (310), so that the particle (P) collection performance of the second dust collection part (300) can be improved.

[0155] The length of the guide portion (500) extending along the circumferential direction of the brake disc (BD) may be equal to or relatively larger than the distance between the end portion of the second cover portion (320) and the end portion of the caliper portion (100).

[0156] The length of the guide portion (500) extending along the circumferential direction of the brake disc (BD) may be relatively smaller than the length of the caliper portion (100) extending along the circumferential direction of the brake disc (BD).

[0157] The length of the guide portion (500) extending along the circumferential direction of the brake disc (BD) may be greater than half the length of the caliper portion (100) extending along the circumferential direction of the brake disc (BD).

[0158] The guide portion (500) can be formed of a high thermal conductivity material with high heat dissipation performance. As a result, even if the guide portion (500) is positioned at a first position to cover the caliper portion (100), heat generated from the caliper portion (100) is allowed to be released to the outside, thereby guiding the movement path of the particle (P) and simultaneously ensuring the cooling efficiency of the brake disc (BD).

[0159] Referring to FIGS. 5 to 7, a particle dust collector (1) according to one embodiment of the present invention may include a control unit (700) capable of adjusting the position of a guide unit (500).

[0160] Specifically, the control unit (700) can adjust the position of the guide unit (500) on the brake disc (BD), and the control unit (700) can adjust the position of the guide unit (500) by controlling the operation of the drive unit (600) that provides power to the guide unit (500).

[0161] The control unit (700) can obtain at least one of the following from the sensor unit (800) described later: speed information of the vehicle, rotational speed information of the brake disc (BD), temperature information of the brake disc (BD), information regarding the amount of generated particles (P), or information regarding the charge amount of particles (P), and can adjust the position of the guide unit (500) using the obtained information.

[0162] Referring to FIGS. 2, FIGS. 3, and FIGS. 6, the control unit (700) can control the operation of the driving unit (600) to position the guide unit (500) at a first position so that the guide unit (500) covers the caliper unit (100).

[0163] When the vehicle speed is high or the brake disc (BD) rotates at high speed, the control unit (700) can control the operation of the drive unit (600) to position the guide unit (500) in a first position so that the guide unit (500) covers the caliper unit (100).

[0164] As a result, the flow of wind (W) into the caliper part (100) is restricted, thereby preventing the phenomenon of the wind (W) escaping to the outside without flowing toward the first dust collection part (200), which has the effect of increasing the dust collection efficiency of particles (P).

[0165] When the amount of particles (P) generated between the brake disc (BD) and the caliper part (100) is large, the control unit (700) can control the operation of the driving unit (600) to position the guide unit (500) at a first position so that the guide unit (500) covers the caliper part (100).

[0166] When the charge amount of the particle (P) is low, the control unit (700) can control the operation of the driving unit (600) to position the guide unit (500) at a first position so that the guide unit (500) covers the caliper unit (100).

[0167] As a result, even if the charge amount of the particle (P) is low, the guide part (500) guides a large amount of particle (P) to flow toward the first dust collection part (200), thereby increasing the amount of particle (P) collected in the first dust collection part (200).

[0168] Referring to FIG. 7, the control unit (700) can control the operation of the driving unit (600) to position the guide unit (500) at a second position so that the caliper unit (100) is exposed to the outside.

[0169] When the temperature of the brake disc (BD) rises above a preset temperature, the control unit (700) controls the operation of the drive unit (600) to move the guide unit (500) to a second position, thereby exposing the caliper unit (100) to the outside.

[0170] As a result, wind (W) is allowed to flow into the interior of the caliper part (100), so that the caliper part (100) or the brake disc (BD) can be effectively cooled by the wind (W).

[0171] That is, the control unit (700) obtains vehicle information from the sensor unit (800) and moves the guide unit (500) to an appropriate position on the brake disc (BD), thereby having the effect of adjusting the dust collection efficiency of the particles (P) and the cooling efficiency of the brake disc (BD) according to the vehicle's operating conditions.

[0172] Referring to FIG. 7, a sensor unit (800) according to one embodiment of the present invention can acquire information such as the speed of a vehicle, the rotational speed of a brake disc (BD), the temperature of a brake disc (BD), information regarding the amount of generated particles (P) or information regarding the charge amount of particles (P), and transmit it to a control unit (700).

[0173] As a result, the control unit (700) can appropriately adjust the position of the guide unit (500) according to the vehicle's operation information, external environment information, etc.

[0174]

[0175] Hereinafter, a particle dust collector (1') according to another embodiment of the present invention will be described.

[0176] A particle dust collector (1') according to another embodiment of the present invention includes a third dust collection unit (400) in which particles (P) collide due to inertia. Since the configuration and operating principle of the particle dust collector (1') according to one embodiment of the present invention are identical, a detailed description is omitted in the scope of overlap.

[0177] FIG. 9 is a schematic diagram illustrating a caliper-type particle dust collector according to another embodiment of the present invention. FIG. 10 is a diagram for explaining the positions of a first dust collector and a third dust collector disposed on a brake disc.

[0178] Referring to FIG. 9 and FIG. 10, a particle dust collector (1') according to another embodiment of the present invention may include a brake disc (BD), a caliper part (100), a first dust collection part (200), a third dust collection part (400), a guide part (500), a driving part (600), a control part (700), and a sensor part (800).

[0179] Since the particle dust collector (1') according to another embodiment of the present invention has the same configuration as the particle dust collector (1) according to one embodiment of the present invention, except for including a third dust collection unit (400), the description of the brake disc (BD), caliper unit (100), first dust collection unit (200), guide unit (500), driving unit (600), control unit (700), and sensor unit (800) of the particle dust collector (1') according to another embodiment of the present invention is omitted.

[0180] Various sizes of dust particles (P) can be generated on the brake disc (BD).

[0181] Among the particles (P) generated in the brake disc (BD), particles (P) with small size or mass may have relatively small inertial force applied to the particles (P) and may be rapidly charged due to friction with the brake pad, etc.

[0182] Accordingly, most of the particles (P) with small size or mass can be discharged from the caliper part (100) and move circumferentially along the brake disc (BD), and through this, most of the particles (P) with small size or mass can move to the first dust collection part (200) and be collected by the electric field of the first dust collection part (200).

[0183] However, unlike this, in the case of particles (P) that are relatively large in size or mass among the particles (P) generated from the brake disc (BD), a large inertial force may act on the particles (P).

[0184] In this case, most of the particles (P) discharged from the caliper part (100) can move in the radial direction of the brake disc (BD) by centrifugal force or inertial force, and through this, most of the particles (P) with large size or mass are discharged to the outside of the brake disc (BD) before moving to the first dust collection part (200), thereby reducing the collection efficiency of the particle dust collection device (1').

[0185] A particle dust collector (1') according to another embodiment of the present invention is provided with a third dust collector (400) that collects particles (P) between the first dust collector (200) and the caliper (100), thereby effectively collecting particles (P) that are about to be discharged to the outside between the first dust collector (200) and the caliper (100).

[0186] Referring to FIGS. 9 and 10, the third dust collection unit (400) collects dust particles (P) by colliding with them in inertia, and may include an inertia collision unit (410) and a third cover unit (420).

[0187] Referring to FIG. 9, the third dust collection unit (400) can be positioned between the first dust collection unit (200) and the caliper unit (100).

[0188] The third dust collection unit (400) may be positioned on the outer periphery of the brake disc (BD). For example, the third dust collection unit (400) may be positioned to face the other outer side of the brake disc (BD) that is in contact with the brake pad.

[0189] Referring to FIG. 10, the inertial collision part (410) is positioned on the outer circumference of the brake disc (BD) and can collide inertially with a particle (P) moving outward from the surface of the brake disc (BD) by centrifugal force.

[0190] The inertial collision section (410) can be formed in the shape of a plate or a slit that is placed on the path of movement of the dust particles (P).

[0191] The inertia collision section (410) can be positioned between the first dust collection section (200) and the caliper section (100), and specifically, can be positioned on the outer circumference of the brake disc (BD) located in the space between the first dust collection section (200) and the caliper section (100).

[0192] Referring to FIG. 10, the inertial collision part (410) may be positioned on the reference axis (CL), for example, the inertial collision part (410) may be positioned on the area where the reference axis (CL) and the outer edge of the brake disc (BD) intersect.

[0193] As a result, an inertial collision part (410) is positioned on the path of a particle (P) that moves outward by centrifugal force between the first and second dust collection plates (210, 220) and the caliper part (100), so that the inertial collision part (410) can effectively collect the particle (P) by inertial collision with the particle (P) that moves in the radial direction of the brake disc (BD) between the first and second dust collection plates (210, 220) and the caliper part (100).

[0194] The inertial collision part (410) may be formed in the shape of a flat plate with the reference axis (CL) as the normal vector. However, it is not limited thereto, and the inertial collision part (410) may be formed as a plate that forms a preset angle with the reference axis (CL).

[0195] The inertial collision section (410) may consist of a plurality of slits arranged sequentially along the circumferential direction of the brake disc (BD). As a result, particles (P) can collide inertially with the slits and be captured in the slits, and air can flow through the space between the slits.

[0196] Referring to FIG. 9, the third cover portion (420) may be positioned between the first dust collection portion (200) and the caliper portion (100), and may be positioned spaced apart from the caliper portion (100).

[0197] For example, one end of the third cover part (420) facing the caliper part (100) and the other end of the caliper part (100) facing the third cover part (420) may be spaced apart from each other by a predetermined distance.

[0198] As a result, the brake disc (BD) can be exposed to the outside through the gap between the caliper part (100) and the first cover part (240), so that the brake disc (BD) is exposed to the outside immediately after friction with the caliper part (100), thereby allowing the brake disc (BD) to be easily cooled.

[0199] The third cover portion (420) can be fixed in position on the first cover portion (240), and for example, the third cover portion (420) and the first cover portion (240) can be formed integrally.

[0200] As a result, particles (P) that are not captured in the inertial collision part (410) positioned inside the second cover part (320) are not released to the outside by the first cover part (240) or the third cover part (420), and can move stably to the first dust collection plate (210) or the second dust collection plate (220).

[0201] A caliper-type particle dust collector (1, 1') according to embodiments of the present invention includes a first dust collection unit (200) that collects particles (P) by an electric field and a second dust collection unit (300) to a third dust collection unit (400) that collects particles (P) by a magnetic field or inertial collision force, thereby having the effect of effectively collecting dust particles (P) of various sizes regardless of the size of the particles (P).

[0202] Each of the embodiments described above can be implemented independently, but it goes without saying that the structure of each embodiment can be applied in combination to other embodiments.

[0203] As such, the present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.

[0204] The specific practices described in the embodiments are examples and do not limit the scope of the embodiments in any way. Furthermore, unless specifically stated as "essential," "importantly," etc., components may not be strictly necessary for the application of the invention.

Furthermore, if a range is described in the embodiments, it is considered to include the invention to which individual values ​​belonging to said range are applied (unless otherwise stated), and this is equivalent to describing each individual value constituting said range in the detailed description.
