Description

Technical Field

[0001] The present application relates to the technical field of automobile sunroof guide rails, and in particular to a self-cleaning automobile sunroof guide rail with waterproof and dustproof functions. Background Art

[0002] The car sunroof guide rail is an indispensable component of the sunroof system. It is responsible for supporting and guiding the opening and closing movement of the sunroof glass. These guide rails are usually made of high-strength metal materials, such as aluminum alloy or stainless steel, which have good corrosion resistance and strength. The design of the guide rail is usually matched with the shape and size of the car's sunroof to ensure the correct installation and function of the sunroof. The surface of the guide rail may be specially treated, such as anodizing or electroplating, to improve its corrosion resistance and wear resistance.

[0003] The structure of the guide rail includes a sliding groove, a fixing point and a lubrication system. The sliding groove allows the sunroof glass to slide along the guide rail, the fixing point ensures the stable installation of the guide rail on the vehicle, and the lubrication system ensures the smooth movement of the sunroof glass. The guide rail also contains a sealing strip to prevent rain and dust from entering the vehicle.

[0004] Waterproof, dustproof and self-cleaning functions are very important for the sunroof rails of automobiles, especially in adverse weather conditions. The waterproof function can prevent moisture from penetrating into the inside of the rails, thereby avoiding rust and corrosion and extending the service life of the rails. The dustproof function helps to reduce the accumulation of dust and dirt, keeping the rails clean and running smoothly. For example, the automatic cleaning sunroof of an automobile with application number CN201510831848.3 relates to the technical field of automobile sunroof accessories. The prior art includes a sunroof cover plate, on which a window is provided for connecting the outside world with the interior space of the vehicle. One side is provided with an embedded skylight glass embedded in the skylight cover, and a pair of guide rails parallel to each other are provided on both sides of the skylight cover. The embedded skylight glass can slide flexibly on the guide rails. Cleaning brushes are detachably provided on the skylight cover at the upper and lower parts relative to the position where the embedded skylight glass extends into the window. The heads of the cleaning brushes are all directed to contact the corresponding side of the embedded skylight glass. A storage groove is provided at the lower part of the cleaning brush arranged inside the vehicle, and the storage groove is buckled on the skylight cover. The above-mentioned prior art realizes that the skylight can be automatically cleaned when it is opened or closed, so that dust will not accumulate no matter how long it takes.

[0005] However, the above-mentioned prior art still has some defects when cleaning the car sunroof:

[0006] 1. When cleaning the car sunroof, the above-mentioned prior art makes the cleaning brush remain still and contact the glass by sliding the sunroof glass, thereby cleaning the glass surface. This cleaning method relies on the interactive opening and closing function of the sunroof, which means that only sunroofs with this function can use this cleaning method. For those sunroofs that do not have the sliding opening and closing function, this cleaning method is not applicable. At the same time, since cleaning relies on the opening and closing action of the sunroof, the frequency of cleaning is limited by the frequency of use of the sunroof. The cleaning effect may be affected by factors such as the sliding speed of the sunroof glass, the material and design of the cleaning brush, etc. If these factors are not well controlled, inconsistent cleaning effects may result.

[0007] 2. When cleaning a car sunroof, the above-mentioned prior art uses a cleaning brush installed on the sunroof cover plate to extend into the window position, with the head of the cleaning brush facing the embedded sunroof glass to clean the glass. During the long-term cleaning process, some dust on both sides of the cleaning brush may fall into the guide rails on both sides. The dust may increase the friction between the guide rails and the sunroof glass, causing wear of the guide rails and the glass. At the same time, dust accumulation may cause the sunroof glass to get stuck in the guide rails, affecting its smooth opening and closing. The dust may also affect the sealing performance of the sunroof, causing water and dust to enter the car.

[0008] Based on this, and in accordance with the above-mentioned viewpoints, the existing technology still has room for improvement in self-cleaning methods. Summary of the invention

DETAILED DESCRIPTION

[0040] The following is combined with Figures 1 to 12 This application is described in further detail.

[0041] The embodiment of the present application discloses a self-cleaning automobile sunroof guide rail with waterproof and dustproof functions, which can be passively cleaned through the opening and closing function of the automobile sunroof, and can also actively clean the automobile sunroof glass through the drive of the automobile, thereby being able to clean a sunroof that does not have an interactive opening and closing function.

[0042] Example 1: Reference Figures 1 to 3A self-cleaning automobile sunroof guide rail with waterproof and dustproof functions includes a slide rail 1. The slide rail 1 is the basic structure of the sunroof guide rail system and is responsible for guiding the sliding of the sunroof glass 3. Slide blocks 2 are symmetrically and slidably arranged on the two slide rails 1. Sunroof glass 3 is commonly arranged between multiple slide blocks 2. The slide blocks 2 are installed on the slide rails 1 and are in direct contact with the sunroof glass 3. They are responsible for supporting and guiding the opening and closing of the sunroof glass 3. The sunroof glass 3 is the main component of the sunroof system and is responsible for providing a visual connection between the interior of the car and the outside world.

[0043] Support bars 11 are provided at both ends of the two slide rails 1. The support bars 11 are installed at both ends of the slide rails 1 to provide additional support for the slide rails 1 to ensure the stability and durability of the sunroof system. A dust box 4 is provided between the two slide rails 1 for sliding. The dust box 4 is used to collect dust and dirt removed from the sunroof glass 3 during the cleaning process.

[0044] When cleaning the sunroof of the car, the cleaner 5 is provided between the two slide rails 1 and is located in the dust box 4 , and is responsible for cleaning the sunroof glass 3 .

[0045] Reference Figure 4 and Figure 5 Specifically, the cleaner 5 includes a sliding groove 51 opened at the bottom of the slide rail 1, a sliding block 52 is slidably arranged in the sliding groove 51, and a lower cleaning scraper 53 is commonly arranged between the two sliding blocks 52. The lower cleaning scraper 53 is located on the lower side of the sunroof glass 3, and its upper end surface contacts the lower end surface of the sunroof glass 3, and is used to remove dust and dirt on the upper side of the sunroof glass 3.

[0046] An upper cleaning scraper 54 is commonly provided between the two sliding blocks 52 . The upper cleaning scraper 54 is located on the upper side of the sunroof glass 3 , and its lower end surface contacts the upper end surface of the sunroof glass 3 . The upper cleaning scraper 54 is responsible for cleaning the upper surface of the sunroof glass 3 , and is used to remove dust and dirt on the lower side of the sunroof glass 3 .

[0047] When the sunroof motor drives the sunroof glass 3 to move and open, the upper end surface of the lower cleaning scraper 53 contacts the lower end surface of the sunroof glass 3. As the glass slides, the lower cleaning scraper 53 slides in the slide rail 1 to clean the lower end surface of the sunroof glass 3 and remove dust, dirt and moisture on the glass surface. At the same time, the lower end surface of the upper cleaning scraper 54 contacts the upper end surface of the sunroof glass 3. The upper cleaning scraper 54 slides in the slide rail 1 to clean the upper end surface of the sunroof glass 3 and also remove dust, dirt and moisture on the glass surface.

[0048] As the skylight glass 3 slides, dust, dirt, etc. scraped off by the upper cleaning blade 54 and the lower cleaning blade 53 fall into the dust collection box 4. The inner wall of the dust collection box 4 has adsorbability. The dust collection box 4 can collect and hold dust and dirt, reducing the possibility of dust moving inside the dust collection box 4 or being blown away by the wind. The adsorbent inner wall helps prevent dust and dirt from forming a loose accumulation on the inner wall of the dust collection box 4, thereby reducing the risk of dust leaking into or out of the vehicle due to vibration or jolting during vehicle driving, thus achieving passive cleaning of the skylight glass 3.

[0049] During the process of the skylight glass 3 moving and opening, the lower cleaning blade 53 and the upper cleaning blade 54 work together to clean the upper and lower end faces of the skylight glass 3. The material and design of the cleaning blades need to be able to adapt to the cleaning requirements under different weather conditions while ensuring gentle cleaning of the glass. The design of the upper cleaning blade 54 and the lower cleaning blade 53 needs to consider the contact pressure with the glass to ensure the cleaning effect without damaging the glass.

[0050] Among them, considering that the skylights of many cars do not have the opening and closing function, a transmission shaft 55 is rotatably arranged between the two sliding blocks 52, and connecting grooves 56 are formed on both sides of the upper cleaning blade 54.

[0051] When the user activates the skylight cleaning function through the control switch or button inside the car, a signal is sent to the electronic control unit (ECU) of the car. After receiving the instruction to clean the skylight, the electronic control unit (ECU) sends a signal to the drive system of the car. The drive system inside the car drives the drive shafts 58 respectively arranged at both ends of the two support bars 11 to rotate. The rotating drive shafts 58 are threadedly connected to the connecting blocks 561, driving the connecting blocks 561 slidably arranged in the connecting grooves 56 to drive the upper cleaning blade 54 to move to the other side of the skylight glass 3.

[0052] Refer to Figure 6 and Figure 7 , at the same time, U-shaped connecting blocks 57 are rotatably arranged at both ends of the transmission shaft 55. The transmission shaft 55 is driven by connecting the two vertical ends of the U-shaped connecting blocks 57 to the connecting blocks 561, so that the transmission shaft 55 drives the two sliding blocks 52 and the drive shafts 58 to move together, and through transmission, the lower cleaning blade 53 and the upper cleaning blade 54 move synchronously to the other side of the skylight glass 3 until the upper cleaning blade 54 and the lower cleaning blade 53 move to the other side of the skylight glass 3.

[0053] In the process of the upper cleaning scraper 54 and the lower cleaning scraper 53 moving to the other end of the skylight glass 3, the opposite sides of the two dust box 4 slide rails 1 are provided with a guide groove 1 61 and a guide groove 2 62. The protrusions 64 rotatably arranged on both sides of the upper cleaning scraper 54 will pass through the interconnected inclined grooves 63 arranged at one end of the guide groove 1 61 and the guide groove 2 62, and enter the guide groove 2 62 from the guide groove 1 61. At this time, the protrusions 64 will force the upper cleaning scraper 54 to move upward, and the upper cleaning scraper 54 will break away from the contact with the upper surface of the skylight glass 3 until the upper cleaning scraper 54 moves to the other side of the skylight glass 3.

[0054] When the upper cleaning scraper 54 moves upward, the upper cleaning scraper 54 will drive the transmission racks 541 set at both ends thereof to move upward together. The transmission racks 541 engage with the transmission gears 551 set at both ends of the transmission shaft 55 to rotate. The transmission gears 551 will drive the transmission shaft 55 to rotate by a certain angle. Since the lower cleaning scraper 53 is set between the two sliding blocks 52 by the rotation of the transmission shaft 55, the transmission shaft 55 will drive the lower cleaning scraper 53 to deflect by a certain angle, so that the lower cleaning scraper 53 is out of contact with the lower surface of the sunroof glass 3 until it moves to the other side of the sunroof glass 3.

[0055] The upper cleaning scraper 54 and the lower cleaning scraper 53 are both out of contact with the sunroof glass 3 until they move to the other side of the sunroof glass 3. Then the car's driving system drives the two driving shafts 58 to reverse, and the rotating driving shafts 58 drive the connecting block 561 sliding in the connecting groove 56 through a threaded connection to drive the upper cleaning scraper 54 to move to one side of the sunroof glass 3.

[0056] Reference Figure 8 and Fig. 9 In the process of the upper cleaning scraper 54 and the lower cleaning scraper 53 moving to one end of the sunroof glass 3, the protrusion 64 will pass through the interconnected inclined groove 63 set at the other end of the guide groove 1 61 and the guide groove 2 62, and enter the guide groove 1 61 from the guide groove 2 62. At this time, the protrusion 64 will force the upper cleaning scraper 54 to move downward, and the upper cleaning scraper 54 will contact the upper surface of the sunroof glass 3 until the upper cleaning scraper 54 moves to the initial position on one side of the sunroof glass 3.

[0057] When the upper cleaning scraper 54 moves downward, the upper cleaning scraper 54 will drive the transmission racks 541 set at both ends thereof to move downward together. The transmission racks 541 engage with the transmission gears 551 set at both ends of the transmission shaft 55 to rotate. The transmission gears 551 will drive the transmission shaft 55 to move and deflect a certain angle. Since the lower cleaning scraper 53 is set between the two sliding blocks 52 by the rotation of the transmission shaft 55, the transmission shaft 55 will drive the lower cleaning scraper 53 to rotate together and return to the initial state, so that the lower cleaning scraper 53 contacts the lower surface of the sunroof glass 3 until it moves to the initial position on one side of the sunroof glass 3.

[0058] The upper cleaning scraper 54 and the lower cleaning scraper 53 are both in contact with the sunroof glass 3 until they move to the initial position on one side of the sunroof glass 3 , during which the upper cleaning scraper 54 and the lower cleaning scraper 53 scrape off dust and dirt on the sunroof glass 3 .

[0059] Therefore, both ends of guide groove 1 61 and guide groove 2 62 are provided with interconnected oblique grooves 63, and guide groove 1 61 and guide groove 2 62 of dust box 4 are interconnected through the oblique grooves 63 at both ends to form a return groove 6, and both sides of the upper cleaning scraper 54 are rotatably provided with protrusions 64 located in the return groove 6, and the oblique grooves 63 allow the protrusions 64 to transition from guide groove 1 61 to guide groove 2 62, or from guide groove 2 62 to guide groove 1 61.

[0060] During this process, since the connecting block 561 is connected to the dust box 4, it drives the dust box 4 to move together. The driving shaft 58 slides through the dust box 4 without affecting the movement of the dust box 4, ensuring the collection of the scraped dust and dirt, thereby realizing active cleaning of the car sunroof.

[0061] The dust box 4 includes an upper cover 41 and a lower cover 42, which are detachably connected to the connecting block 561, and the upper cover 41 and the lower cover 42 are connected by a detachable connection. This design allows the user to easily open the dust box 4, and the user can conveniently remove the dust and dirt in the dust box 4, which simplifies the cleaning process, ensures the cleaning effect of the dust box 4, and reduces the time and effort required for maintenance.

[0062] Example 2: Reference Figure 8 and Fig. 9 , based on the first embodiment,

[0063] A shifting block 65 is provided at the connection between the guide groove 1 61 and the guide groove 2 62 and the two inclined grooves 63 for rotation via a torsion spring (not shown in the figure).

[0064] The protrusion 64 will resist the shift block 65 and compress the torsion spring, allowing the protrusion 64 to pass smoothly. The compressed torsion spring will then force the shift block 65 to rotate back to its original position, ensuring that the protrusion 64 passes through the inclined groove 63 and accurately enters the guide groove 2 62 from the guide groove 1 61, or the protrusion 64 passes through the inclined groove 63 and accurately enters the guide groove 1 61 from the guide groove 2 62. During the movement of the protrusion 64, ensure that the protrusion 64 accurately enters the guide groove 1 61 or the guide groove 2 62, so that the protrusion 64 always maintains a moving direction in the return groove 6 to avoid reverse movement.

[0065] Example 3: Reference Fig.10 , Fig.11 and Fig.12 , based on the first and second embodiments,

[0066] A wiping piece 7 is provided on one side of the lower cleaning blade 53 , and the wiping piece 7 can further wipe the glass surface to remove tiny particles, water stains or oil stains that may not be removed by the upper cleaning blade 54 and the lower cleaning blade 53 .

[0067] Specifically, the wiping member 7 includes wiping shafts 71 symmetrically and rotatably arranged on the lower cleaning blade 53 , and a transmission wheel 72 is arranged on each of the two wiping shafts 71 .

[0068] When the upper cleaning scraper 54 and the lower cleaning scraper 53 move for passive cleaning of the automobile sunroof glass 3, and the upper cleaning scraper 54 and the lower cleaning scraper 53 move for active cleaning, the driving motor 721 arranged on the lower cleaning scraper 53 will be started, and the driving motor 721 will drive one of the wiping shafts 71 connected to it to rotate, and the rotating wiping shaft 71 will drive the wiping belt 73 sleeved between the two transmission wheels 72, so that the wiping belt 73 drives the other wiping shaft 71 to rotate together, and the wiping belt 73 is transmitted between the two transmission wheels 72 to ensure the continuous movement of the wiping belt 73, and the wiping belt 73 contacts the lower surface of the sunroof glass 3, and the sunroof glass 3 is wiped by the dynamic transmission of the wiping belt 73.

[0069] The portion of the wiping belt 73 that is in direct contact with the lower surface of the sunroof glass 3 is made of a soft material with cleaning ability, such as sponge, soft rubber or synthetic fiber.

[0070] During the movement of the wiping belt 73, the wiping belt 73 will slide through the dust scraper 74 slidably arranged on one side of the lower cleaning scraper 53, and the dust scraper 74 will clean the wiping belt 73, remove the dust and dirt collected by the wiping belt 73 during the cleaning process, and make the dust and dirt fall into the dust collecting box 4, and be cleaned by the dust scraper 74, so as to maintain the cleanliness of the wiping belt 73 and improve its cleaning efficiency and service life.

[0071] The adjusting screw 741 which is rotatably arranged on the lower cleaning scraper 53 through the bracket is turned, and the adjusting screw 741 will force the scraper plate 74 to move up and down on the lower cleaning scraper 53 through threaded cooperation, and the scraper plate 74 will pull the wiping belt 73 to move synchronously, so that the wiping belt 73 is tightened or loosened, thereby adjusting the contact pressure between the wiping belt 73 and the scraper plate 74. By maintaining appropriate contact pressure between the wiping belt 73 and the scraper plate 74, the dirt on the wiping belt 73 can be effectively removed without causing excessive wear to the wiping belt 73. At the same time, the tightening and loosening of the wiping belt 73 will have different cleaning effects on the sunroof glass 3. That is, the tighter the wiping belt 73 is, the more closely it fits the surface of the sunroof glass 3, thereby providing a more uniform and consistent cleaning effect.

[0072] A cleaning box 75 is provided on one side of the lower cleaning scraper 53, and cleaning liquid is injected into the cleaning box 75. A plurality of rotating shafts 751 are rotatably provided in the cleaning box 75. During the movement of the wiping belt 73, the wiping belt 73 slides through the cleaning box 75 and contacts with the upper surface of the cleaning belt 76. The wiping belt 73 will rub against the cleaning belt 76 sleeved between the plurality of rotating shafts 751, so that the cleaning belt 76 is transmitted between the plurality of rotating shafts 751. The cleaning belt 76 will wipe the surface of the wiping belt 73. After the scraper plate 74 removes dust and dirt, the wiping belt 73 is further cleaned.

[0073] At the same time, the cleaning liquid in the cleaning box 75 will clean the cleaning belt 76, and the cleaning liquid will be attached to the wiping belt 73 through the cleaning belt 76. The cleaning liquid can improve the cleaning effect and help dissolve and remove dirt, grease and water stains on the glass surface.

[0074] Cleaning support plates 77 located above the wiping belt 73 are slidably arranged on both sides of the cleaning box 75. The return spring 78 arranged between the upper end of the cleaning support plate 77 and the cleaning box 75 will push the cleaning support plate 77. The cleaning support plates 77 on both sides will drive the roller 771 rotatingly arranged between the two cleaning support plates 77 to press on the wiping belt 73 and rotate with the transmission of the wiping belt 73, thereby ensuring that the wiping belt 73 is always in contact with the cleaning belt 76, thereby improving the cleaning effect of the cleaning belt 76 on the wiping belt 73.

[0075] Among them, when the upper cleaning scraper 54 moves upward, the transmission shaft 55 will drive the lower cleaning scraper 53 to deflect at a certain angle, so that the lower cleaning scraper 53 is out of contact with the lower surface of the sunroof glass 3, until it moves to the other side of the sunroof glass 3, the lower cleaning scraper 53 will drive the entire wiping member 7 to deflect at a certain angle, so that the wiping belt 73 is out of contact with the sunroof glass 3.

[0076] When the upper cleaning scraper 54 moves downward, the transmission shaft 55 will drive the lower cleaning scraper 53 to rotate back to the initial middle state, and the lower cleaning scraper 53 will also drive the wiping member 7 to the initial middle state, so that the wiping belt 73 contacts the sunroof glass 3.

[0077] The implementation principle of the present invention is:

[0078] (1): When the sunroof motor drives the sunroof glass 3 to move and open, the upper end surface of the lower cleaning scraper 53 contacts the lower end surface of the sunroof glass 3. As the glass slides, the lower cleaning scraper 53 slides in the slide rail 1 to clean the lower end surface of the sunroof glass 3 and remove dust, dirt and moisture on the glass surface. At the same time, the lower end surface of the upper cleaning scraper 54 contacts the upper end surface of the sunroof glass 3. The upper cleaning scraper 54 slides in the slide rail 1 to clean the upper end surface of the sunroof glass 3 and also remove dust, dirt and moisture on the glass surface.

[0079] (2): The driving system in the automobile drives the driving shaft 58 to rotate. The rotating driving shaft 58 drives the connecting block 561 slidingly arranged in the connecting groove 56 to drive the upper cleaning scraper 54 to move to the other side of the sunroof glass 3. The upper cleaning scraper 54 and the lower cleaning scraper 53 are both out of contact with the sunroof glass 3 until they move to the other side of the sunroof glass 3. Then, the driving system of the automobile drives the two driving shafts 58 to reverse. The rotating driving shaft 58 will drive the connecting block 561 slidingly arranged in the connecting groove 56 through a threaded connection to drive the upper cleaning scraper 54 to move to one side of the sunroof glass 3.

[0080] (3): In the process of the upper cleaning scraper 54 and the lower cleaning scraper 53 moving to one end of the sunroof glass 3, the protrusion 64 will enter the guide groove 1 61 from the guide groove 2 62. At this time, the protrusion 64 will force the upper cleaning scraper 54 to move downward, and the upper cleaning scraper 54 will contact the upper surface of the sunroof glass 3 until the upper cleaning scraper 54 moves to the initial position on one side of the sunroof glass 3. In the process of the upper cleaning scraper 54 and the lower cleaning scraper 53 both contacting the sunroof glass 3 until they move to the initial position on one side of the sunroof glass 3, the upper cleaning scraper 54 and the lower cleaning scraper 53 will scrape off the dust and dirt on the sunroof glass 3.

[0081] (4): When the upper cleaning scraper 54 and the lower cleaning scraper 53 move to perform passive cleaning on the automobile sunroof glass 3, and the upper cleaning scraper 54 and the lower cleaning scraper 53 move to perform active cleaning, the wiping belt 73 contacts the lower surface of the sunroof glass 3, and the wiping belt 73 drives the transmission to wipe the sunroof glass 3.

[0082] (5): During the movement of the wiping belt 73, the wiping belt 73 will rub against the cleaning belt 76 sleeved between the multiple rotating shafts 751, so that the cleaning belt 76 is transmitted between the multiple rotating shafts 751. The cleaning belt 76 will wipe the surface of the wiping belt 73. After the scraper plate 74 removes dust and dirt, the wiping belt 73 is further cleaned.

[0083] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
