A cleaning device for an electronic throttle assembly

Abstract

The present invention discloses a cleaning device for an electronic throttle assembly. The present invention relates to the technical field of cleaning devices. During cleaning, a scraper is usually used to scrape in cooperation with the dissolution of a cleaning agent. After the carbon deposit layer is scraped off, the scraper still scrapes the inner wall of the throttle valve, resulting in serious wear of the inner wall of the throttle valve. With the cooperation of the scraping cylinder roller and the arc brush plate, when the rotating plate overcomes the pulling of the elastic block and starts to expand the rotation diameter under the action of the rotational centrifugal force, when there is a carbon deposit layer on the inner wall of the throttle valve, the scraping cylinder roller contacts the carbon deposit layer and applies pressure to the carbon deposit layer through the action of centrifugal force, and uses the convex strips to clean the carbon deposit layer. After the carbon deposit layer is cleaned, the rotating plate continues to rotate along the axis of the rotating column to expand the rotation diameter. At this time, the scraping cylinder roller does not contact the inner wall of the throttle valve, and the arc brush plate starts to contact the inner wall, avoiding scraping the inner wall of the throttle valve after the carbon deposit layer of the throttle valve is cleaned, which causes serious wear of the inner wall of the throttle valve.

Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a cleaning device for an electronic throttle assembly. Background Art

[0002] At present, the throttle is an important component in the intake system of an automobile engine. Its main function is to control the air flow entering the engine, thereby regulating the power output and speed of the engine. When the driver steps on the accelerator pedal, a signal is transmitted to the throttle flap through the drive mechanism, and the opening of the flap changes, thereby controlling the amount of air entering the engine. During the operation of the engine, the high-temperature mixed gas in the combustion chamber will flow back to the intake passage in small amounts through the intake valve. The unburned fuel and oil vapor in it will cool and condense on the surface of the throttle, mix with impurities such as dust in the air, and gradually form carbon deposits.

[0003] When cleaning the throttle, since there is a layer of carbon deposit in the intake passage of the inner wall of the throttle, scraping with a scraper in cooperation with the dissolution of a cleaning agent is usually used for cleaning. However, during the scraping process, after the carbon deposit layer is scraped off, the scraper still scrapes the inner wall of the throttle, resulting in serious wear of the inner wall of the throttle and affecting the control of the intake air volume during use. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A cleaning device for an electronic throttle assembly, comprising:

[0005] A frame body, on the top of which a slide rail frame is fixedly installed, and cylinders are fixedly installed on both sides inside the slide rail frame;

[0006] A fixing mechanism, which is used to clamp and position the throttle assembly. The fixing mechanism is slidably installed on the top of the slide rail frame, and the fixing mechanism is symmetrically installed along the central axis position of the slide rail frame;

[0007] A brush piece mechanism, which is installed inside the fixing mechanism, and a brush barrel mechanism is fixedly installed on the outside of the brush piece mechanism;

[0008] Among them, the brush cylinder mechanism includes a fixed cylinder. One end of the fixed cylinder is fixedly connected with a support ring. The inner wall of the support ring is fixedly connected with a brush piece mechanism. The outer side of the fixed cylinder is rotationally connected with a rotating column through a fastener. The rotating columns are evenly installed along the center position of the fixed cylinder. The outer sides of the rotating columns are fixedly connected with rotating plates. One end of each rotating plate away from the rotating column is fixedly installed with a top plate. The top of the top plate is fixedly installed with an arc brush plate. One side of the top plate is rotationally installed with a scraping cylinder roller. Through the cooperation of the scraping cylinder roller and the arc brush plate, under the action of rotational centrifugal force, when the rotating plate overcomes the pulling of the elastic block and starts to expand the rotation diameter, when there is a carbon deposit layer on the inner wall of the throttle valve, the scraping cylinder roller contacts the carbon deposit layer, and the carbon deposit layer is pressed under the action of centrifugal force, and the carbon deposit layer is cleaned by the convex strips. After the carbon deposit layer is cleaned, the rotating plate continues to rotate along the axis of the rotating column to expand the rotation diameter. At this time, the scraping cylinder roller does not contact the inner wall of the throttle valve, and the arc brush plate starts to contact the inner wall, avoiding that after the carbon deposit layer of the throttle valve is cleaned during cleaning, the inner wall is still scraped, resulting in serious wear of the inner wall of the throttle valve and affecting the control of the intake air volume. The rotating plate is inclined to the side away from the scraping cylinder roller, and an elastic block is fixedly connected to the side of the rotating plate away from the scraping cylinder roller. The elastic blocks are symmetrically installed along the central position of the axis of the rotating plate. Through the elastic action of the elastic blocks, the rotating plate is pulled and inclined before rotation, so that the scraping cylinder roller is lifted. At the same time, when the scraping cylinder roller and the arc brush plate clean the throttle valve, the pressure between the throttle valve and the scraping cylinder roller or the arc brush plate is buffered, avoiding excessive pressure and serious wear of the inner wall when the throttle valve is inclined, and affecting the use effect after cleaning. One end of the elastic block away from the rotating plate is fixedly connected to the outer side of the fixed cylinder. The outer side of the scraping cylinder roller is provided with convex strips.

[0009] Preferably, the fixing mechanism includes a sliding seat. The inner wall of the sliding seat is slidably adapted to the top of the sliding rail frame, and the sliding seats are symmetrically installed along the central position of the axis of the sliding rail frame. The bottom of the sliding seat on the non-opposite side is connected to the output end of the cylinder. The tops of the sliding seats are fixedly installed with sleeve plates. Circular empty grooves are opened at the tops of the outer sides of the sleeve plates, and fixing disks are fixedly installed at the tops of the opposite sides of the sleeve plates. Opposite surfaces of the fixing disks are fixedly installed with ejector rods. Through the cooperation of the ejector rods and the elastic gasket rings, during the process of gradually applying pressure, the ejector rods gradually approach the planes on both sides of the throttle valve through the through holes of the rubber disks. When the ejector rods contact the planes on both sides of the throttle valve, the fixing is completed. When the ejector rods contact, the angle of the throttle valve is positioned, avoiding the inclination of the throttle valve relative to the brush piece mechanism and the brush cylinder mechanism during cleaning, resulting in excessive pressure on some areas and serious wear, and some other areas cannot be contacted, reducing the cleaning effect.

[0010] Preferably, the ejector rods are symmetrically installed along the central axis position of the fixed disk, and a sliding hole disk is slidably installed at one end of the outer side of the ejector rod away from the fixed disk. Sliding holes are evenly formed in the outer side of the sliding hole disk, and the sliding hole disk is slidably adapted to the outer side of the ejector rod through the sliding holes. A rubber disk is fixedly installed on one side of the sliding hole disk away from the fixed disk. Water guide grooves are evenly arranged on the outer side of the rubber disk. Through the water guide grooves of the rubber disk, during the tilting process, the cleaning agent sprayed inside the throttle valve is blocked from splashing everywhere. At the same time, after the rubber disk deforms when contacting both sides of the throttle valve, the contact area is increased, preventing the throttle valve from rotating during cleaning and affecting the cleaning work. Through holes are evenly formed in the outer side of the rubber disk, and the through holes of the rubber disk correspond to the sliding holes of the sliding hole disk one by one. An elastic gasket is fixedly installed between the sliding hole disk and the fixed disk, and the elastic gasket is evenly installed along the center position of the fixed disk.

[0011] Preferably, the brush plate mechanism includes a connecting disk. The connecting disk is fixedly installed on the non-opposite surface of the sleeve plate, and motors are fixedly installed at the central positions of the non-opposite surfaces of the connecting disk. A transmission shaft is rotatably connected to the inner wall of the connecting disk. One end of the transmission shaft is connected to the output end of the motor through a coupling, and the other end of the transmission shaft is fixedly connected to a hole disk. Rod holes are evenly formed in the outer side of the hole disk. The outer side of the transmission shaft is fixedly connected to the inner wall of the support ring. Slide rods are slidably installed at the rod holes of the hole disk. One end of the slide rod away from the hole disk is fixedly connected to a support disk. Through the cooperation of the spring and the slide rod, after the brush plate contacts the flap, the same pressure is applied simultaneously on both sides, so that the spring is compressed by the same distance, avoiding unilateral wear at the connection position of the flap due to different pressures on both sides of the flap during cleaning, resulting in the offset of the flap position after cleaning and affecting the rotation of the flap during use, so that the throttle valve cannot control the intake air volume by rotating the flap. A spring is fixedly installed between the support disk and the hole disk, and the spring is evenly installed along the center position of the hole disk and is located outside the slide rod. A clamping block is fixedly installed on one side of the support disk away from the hole disk, and the clamping blocks are evenly installed along the center position of the support disk, and the inner wall of the clamping block is clamped with a brush plate.

[0012] The present invention provides a cleaning device for an electronic throttle assembly. It has the following beneficial effects:

[0013] 1. The cleaning device for the electronic throttle assembly, through the cooperation of the scraping cylinder roller and the arc brush plate, under the action of rotational centrifugal force, when the rotating plate overcomes the pulling of the elastic block and begins to expand the rotation diameter, when there is a carbon deposit layer on the inner wall of the throttle, the scraping cylinder roller contacts the carbon deposit layer, applies pressure to the carbon deposit layer through the action of centrifugal force, and uses the convex strips to clean the carbon deposit layer. After the carbon deposit layer is cleaned, the rotating plate continues to rotate along the axis of the rotating column to expand the rotation diameter. At this time, the scraping cylinder roller does not contact the inner wall of the throttle, and the arc brush plate begins to contact the inner wall, avoiding scraping the inner wall of the throttle after the carbon deposit layer of the throttle is cleaned, resulting in serious wear of the inner wall of the throttle and affecting the control of the intake air volume.

[0014] 2. The cleaning device for the electronic throttle assembly, through the elastic action of the elastic block, pulls and inclines the rotating plate before rotation, making the scraping cylinder roller tilt. At the same time, when the scraping cylinder roller and the arc brush plate clean the throttle, it buffers the pressure between the throttle and the scraping cylinder roller or the arc brush plate, avoiding excessive pressure and resulting in serious wear of the inner wall when the throttle tilts, affecting the use effect after cleaning.

[0015] 3. The cleaning device for the electronic throttle assembly, through the cooperation of the ejector rod and the elastic gasket ring, during the process of gradually applying pressure, the ejector rod passes through the through hole of the rubber disk and gradually approaches the planes on both sides of the throttle. When the ejector rod contacts the planes on both sides of the throttle, it is fixed. When the ejector rod contacts, it positions the angle of the throttle, avoiding the throttle tilting relative to the brush plate mechanism and the brush cylinder mechanism during cleaning, resulting in excessive pressure in some areas and serious wear, and some other areas unable to contact, reducing the cleaning effect.

[0016] 4. The cleaning device for the electronic throttle assembly, through the water guide groove of the rubber disk, during the tilting process, blocks the cleaning agent sprayed inside the throttle from splashing everywhere. At the same time, the rubber disk deforms after contacting and pressing on both sides of the throttle, increasing the contact area and preventing the throttle from rotating during cleaning, affecting the progress of the cleaning work.

[0017] 5. The cleaning device for the electronic throttle assembly, through the cooperation of the spring and the sliding rod, after the brush plate contacts the flap, the same pressure is applied on both sides at the same time, so that the spring is compressed by the same distance, avoiding unilateral wear at the connection position of the flap due to different pressures on both sides of the flap during cleaning, resulting in the flap shifting after cleaning and affecting the rotation of the flap during use, making the throttle unable to control the intake air volume by rotating the flap.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0028] The first embodiment is as Figure 1 to Figure 2 shown in Figure 7 to Figure 8 and the present invention provides a technical solution: A cleaning device for an electronic throttle assembly, comprising:

[0029] A frame body 1, on the top of which a slide rail frame 5 is fixedly installed, and cylinders 6 are fixedly installed on both sides inside the slide rail frame 5;

[0030] The fixing mechanism 2 is used to clamp and position the throttle assembly. The fixing mechanism 2 is slidably installed on the top of the slide rail frame 5, and the fixing mechanism 2 is symmetrically installed along the central axis position of the slide rail frame 5;

[0031] The brush piece mechanism 3 is installed inside the fixing mechanism 2, and a brush barrel mechanism 4 is fixedly installed on the outer side of the brush piece mechanism 3;

[0032] Among them, the brush barrel mechanism 4 includes a fixed barrel 41. One end of the fixed barrel 41 is fixedly connected with a support ring 48. The inner wall of the support ring 48 is fixedly connected with the brush piece mechanism 3. The outer side of the fixed barrel 41 is rotationally connected with a rotating column 42 through a fastener. The rotating columns 42 are evenly installed along the center of the circle of the fixed barrel 41 and are connected to the transmission shaft 33 through the support ring 48. When the transmission shaft 33 rotates, the fixed barrel 41 is driven to rotate at a high speed through the support ring 48. During the rotation process, the rotating plate 44 and the top plate 45 are driven by the rotating column 42. Under the action of centrifugal force, the rotating plate 44 drives the elastic block 43 to deform, so that the rotating plate 44 has a tendency perpendicular to the axis of the fixed barrel 41. The outer sides of the rotating columns 42 are fixedly connected with rotating plates 44. One end of the rotating plate 44 away from the rotating column 42 is fixedly installed with a top plate 45. The top of the top plate 45 is fixedly installed with an arc-shaped brush plate 46. One side of the top plate 45 is rotationally installed with a scraping cylinder roller 47. The rotating plate 44 is inclined towards the side away from the scraping cylinder roller 47, and the side of the rotating plate 44 away from the scraping cylinder roller 47 is fixedly connected with an elastic block 43. The elastic blocks 43 are symmetrically installed along the central axis position of the rotating plate 44. During the rotation process, first, the raised scraping cylinder roller 47 contacts the inner wall of the throttle. When there is carbon deposit on the inner wall of the throttle, the inner wall diameter decreases. At this time, the scraping cylinder roller 47 contacts the carbon deposit layer. Through the convex strips evenly arranged on the surface of the scraping cylinder roller 47, friction is generated when contacting the carbon deposit layer, and the carbon deposit layer is rolled and scraped off. At the same time, during the scraping process, the reaction force is transmitted to the elastic block 43 through the top plate 45 and the rotating plate 44. Through the elastic deformation of the elastic block 43, the pressure is buffered during cleaning. When the carbon deposit layer is cleaned, the inner space diameter increases, so that the rotating plate 44 continues to rotate. At this time, the arc-shaped brush plate 46 contacts the inner wall of the throttle and performs a final brushing and cleaning on the inner wall. One end of the elastic block 43 away from the rotating plate 44 is fixedly connected with the outer side of the fixed barrel 41, and the outer side of the scraping cylinder roller 47 is provided with convex strips.

[0033] Second embodiment, on the basis of the first embodiment, please refer to Figure 3 to Figure 4As shown in the figure, the fixing mechanism 2 includes a sliding seat 21. The inner wall of the sliding seat 21 is slidably adapted to the top of the slide rail frame 5, and the sliding seat 21 is symmetrically installed along the axial center position of the slide rail frame 5. The bottom of the non-opposite surfaces of the sliding seat 21 is connected to the output end of the air cylinder 6. The top of the sliding seat 21 is fixedly installed with a sleeve plate 22. By driving the sliding seat 21 to approach each other through the air cylinder 6, the sliding seat 21 drives the sleeve plate 22 to approach. During the approaching process, the rubber disk 24 first contacts the planes on both sides of the throttle valve. After the contact, during the process of continuing to approach and applying pressure by driving through the air cylinder 6, the pressure is transmitted to the slide hole disk 23 through the rubber disk 24, causing the slide hole disk 23 to compress the elastic gasket ring 25 and deform, so that the slide hole disk 23 and the rubber disk 24 move towards the fixed disk 27. Circular empty slots are opened at the top of the outer side of the sleeve plate 22, and fixed disks 27 are fixedly installed at the top of the opposite surfaces of the sleeve plate 22. Push rods 26 are fixedly installed on the opposite surfaces of the fixed disks 27.

[0034] The push rods 26 are symmetrically installed along the axial center position of the fixed disk 27, and a slide hole disk 23 is slidably installed at one end of the outer side of the push rod 26 away from the fixed disk 27. Slide holes are evenly opened on the outer side of the slide hole disk 23, and the slide hole disk 23 is slidably adapted to the outer side of the push rod 26 through the slide holes. A rubber disk 24 is fixedly installed on one side of the slide hole disk 23 away from the fixed disk 27. Water guide grooves are evenly arranged on the outer side of the rubber disk 24. One end of the push rod 26 away from the fixed disk 27 passes through the rubber disk 24 from the through hole of the rubber disk 24 until it contacts the planes on both sides of the throttle valve. Through the contact of the push rod 26, the inclination of the throttle valve is positioned, making the throttle valve parallel to the push rod 26 to complete the fixed clamping. Through holes are evenly opened on the outer side of the rubber disk 24, and the through holes of the rubber disk 24 correspond to the slide holes of the slide hole disk 23 one by one. An elastic gasket ring 25 is fixedly installed between the slide hole disk 23 and the fixed disk 27, and the elastic gasket ring 25 is evenly installed along the center of the fixed disk 27.

[0035] The third embodiment, on the basis of the first and second embodiments, please refer to Figure 5 to Figure 6As shown in the figure, the brush plate mechanism 3 includes a connection disk 32. The connection disk 32 is fixedly installed on the non-opposite surface of the sleeve plate 22, and motors 31 are fixedly installed at the central positions of the non-opposite surfaces of the connection disk 32. The inner wall of the connection disk 32 is rotatably connected to a transmission shaft 33. One end of the transmission shaft 33 is connected to the output end of the motor 31 through a coupling, and the other end of the transmission shaft 33 is fixedly connected to a hole disk 37. Rod holes are evenly formed on the outer side of the hole disk 37. When approaching the throttle valve continuously, the support disk 36 drives the brush plate 34 through the block 35 to penetrate into the throttle valve from the barrel groove of the throttle valve until the brush plate 34 contacts the flap of the throttle valve. After the two brush plates 34 on both sides contact both sides of the flap, pressure is applied to both sides. During the continuous penetration process, the pressure is transmitted to the support disk 36 through the block 35, causing the support disk 36 to drive the slide bar 38 to move, deforming the compression spring 39, and making the slide bar 38 slide in the rod holes of the hole disk 37. At the same time, the elastic force after the deformation of the spring 39 is transmitted to the brush plate 34 through the support disk 36 and the block 35, so that the pressure acts on both sides of the flap through the brush plate 34. The outer side of the transmission shaft 33 is fixedly connected to the inner wall of the support ring 48.

[0036] Slide bars 38 are slidably installed at the rod holes of the hole disk 37. One end of the slide bar 38 away from the hole disk 37 is fixedly connected to a support disk 36. A spring 39 is fixedly installed between the support disk 36 and the hole disk 37. The spring 39 is evenly installed along the center position of the hole disk 37 and is located outside the slide bar 38. During cleaning, the motor 31 drives the transmission shaft 33 to rotate, causing the transmission shaft 33 to drive the hole disk 37 and the brush barrel mechanism 4 to rotate at a high speed. The inner wall of the barrel groove of the throttle valve is cleaned through the brush barrel mechanism 4. The rotating hole disk 37 drives the support disk 36 and the block 35 through the slide bar 38, so that the brush plate 34 rotates and is pressed on both sides of the throttle valve flap for cleaning. A block 35 is fixedly installed on the side of the support disk 36 away from the hole disk 37. The block 35 is evenly installed along the center position of the support disk 36, and the inner wall of the block 35 is clamped with the brush plate 34.

[0037] During use, the worker removes the electronic throttle valve assembly of the vehicle and sprays a cleaning agent into the intake passage of the throttle valve. Then, the throttle valve assembly is placed between the fixing mechanisms 2. When placing it, the motor in the electronic throttle valve assembly is placed above. Then, the air cylinder 6 is started, causing the air cylinder 6 to drive the fixing mechanism 2, and the fixing mechanism 2 drives the brush barrel mechanism 4 and the brush plate mechanism 3 to approach the throttle valve assembly. During the approaching process, the brush plate mechanism 3 first contacts the flap inside the throttle valve, and then presses the flap during the continuous approaching process. The brush barrel mechanism 4 gradually enters the throttle valve barrel. Finally, the fixing mechanism 2 contacts the throttle valve on both sides and positions and clamps it.

[0038] In the brush piece mechanism 3, when continuously approaching the throttle valve, the support disk 36 drives the brush piece plate 34 through the clamping block 35 to penetrate into the interior of the throttle valve from the cylindrical groove of the throttle valve until the brush piece plate 34 contacts the flap of the throttle valve. After the brush piece plates 34 on both sides contact both sides of the flap, pressure is applied to both sides thereof. During the continuous penetration process, the pressure is transmitted to the support disk 36 through the clamping block 35, causing the support disk 36 to drive the sliding rod 38 to move, compressing the spring 39 to deform, and enabling the sliding rod 38 to slide within the rod hole of the hole disk 37. At the same time, the elastic force after the deformation of the spring 39 is transmitted to the brush piece plate 34 through the support disk 36 and the clamping block 35, causing the pressure to act on both sides of the flap through the brush piece plate 34. During cleaning, the motor 31 drives the transmission shaft 33 to rotate, causing the transmission shaft 33 to drive the hole disk 37 and the brush barrel mechanism 4 to rotate at a high speed. The inner wall of the cylindrical groove of the throttle valve is cleaned through the brush barrel mechanism 4, and the rotating hole disk 37 drives the support disk 36 and the clamping block 35 through the sliding rod 38, causing the brush piece plate 34 to apply pressure and rotate for cleaning on both sides of the throttle valve flap.

[0039] In the brush barrel mechanism 4, it is connected to the transmission shaft 33 through the support ring 48. When the transmission shaft 33 rotates, the fixed barrel 41 is driven to rotate at a high speed through the support ring 48. During the rotation process, the rotating column 42 drives the rotating plate 44 and the top plate 45. Under the action of centrifugal force, the rotating plate 44 drives the elastic block 43 to deform, causing the rotating plate 44 to tend to be perpendicular to the axis of the fixed barrel 41. During the rotation process, first, the tilted scraping barrel roller 47 contacts the inner wall of the throttle valve. When there is carbon deposit on the inner wall of the throttle valve, the inner wall diameter decreases. At this time, the scraping barrel roller 47 contacts the carbon deposit layer. Through the convex strips uniformly arranged on the surface of the scraping barrel roller 47, friction is generated when contacting the carbon deposit layer, and the carbon deposit layer is rolled and scraped off. At the same time, during the scraping process, the reaction force is transmitted to the elastic block 43 through the top plate 45 and the rotating plate 44. Through the elastic deformation of the elastic block 43, the pressure is buffered during cleaning. When the carbon deposit layer is cleaned, the inner space diameter increases, causing the rotating plate 44 to continue to rotate. At this time, the arc brush plate 46 contacts the inner wall of the throttle valve and performs a final brushing and cleaning of the inner wall.

[0040] In the fixing mechanism 2, the air cylinder 6 drives the sliding seats 21 to approach each other, causing the sliding seats 21 to drive the sleeve plates 22 to approach. During the approaching process, the rubber disk 24 first contacts the flat surfaces on both sides of the throttle valve. After contact, during the process of the air cylinder 6 driving to continue approaching and applying pressure, the pressure is transmitted to the sliding hole disk 23 through the rubber disk 24, causing the sliding hole disk 23 to compress the elastic cushion ring 25 to deform, and enabling the sliding hole disk 23 and the rubber disk 24 to move towards the fixed disk 27. At this time, one end of the ejector rod 26 away from the fixed disk 27 passes through the through hole of the rubber disk 24 until it contacts the flat surfaces on both sides of the throttle valve. Through the contact of the ejector rod 26, the inclination of the throttle valve is positioned, making the throttle valve parallel to the ejector rod 26, and completing the fixed clamping.

[0041] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
