Description

Technical Field

[0001] The present application relates to the technical field of automobile sunroofs, and in particular to an automobile sunroof guide rail assembly with a drainage function. Background Art

[0002] A car sunroof is a glass or transparent plastic panel structure installed on the top of the vehicle to increase the light inside the car and improve ventilation. The car sunroof rail is a device installed on the roof of the car to control the opening and closing of the roof sunroof. It is a key component in the sunroof assembly and has an important impact on the normal operation and lifespan of the sunroof.

[0003] When the existing automobile sunroof guide rail is in use, the pulley slides inside the sliding groove of the guide rail frame to drive the sunroof glass module to move and realize the opening and closing of the sunroof. However, when the sunroof is opened, external impurities may enter the sliding groove, such as stones, sand and other impurities. When there are impurities inside the sliding groove, the friction between the pulley and the inner wall of the sliding groove will increase, and even large foreign objects will be directly stuck between the pulley and the sliding groove, thereby affecting the normal opening and closing of the sunroof. In addition, for some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., they may be squeezed or cut by the inner wall of the sliding groove under the push of the pulley, causing the inner wall of the sliding groove to be scratched, thereby shortening the service life of the entire guide rail.

[0004] In response to the above technical problems, the patent with patent number CN112193036B discloses a sunroof guide rail with high stability, including a guide rail frame, a sliding groove, a fixed frame structure, a lubrication structure, a buffer structure and a dust removal structure. Sliding grooves are symmetrically arranged on the frame bodies on both sides of the guide rail frame. A fixed frame structure that can move parallel to the sliding groove is slidably installed inside the sliding groove. The inner wall of the middle position of the sliding groove is provided with a lubrication structure that can export lubricating oil. In this patent, when the slider slides to the lubrication structure, the stop block is squeezed into the second sliding hole, the oil guide hole contacts the oil outlet hole, and the oil in the oil chamber flows into the sliding groove, which can play a good lubrication role and help the sunroof slide smoothly. When the slider slides to the end of the sliding groove, it is squeezed and contacted with the buffer block. The elastic force provided by the second spring plays a good buffering role. At the same time, the brush on the fixed block can scrape and remove dust from the outer surface of the glass when the fixed frame structure moves.

[0005] However, the above technical solution has the following defects:

[0006] (1) When the sunroof is open, external impurities such as stones and sand may enter the sliding groove. When there are impurities inside the sliding groove, the friction between the pulley and the inner wall of the sliding groove will increase, and even large foreign objects may be directly stuck between the pulley and the sliding groove, thereby affecting the normal opening and closing of the sunroof. In addition, for some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., they may be squeezed or cut by the inner wall of the sliding groove under the push of the pulley, causing the inner wall of the sliding groove to be scratched, thereby shortening the service life of the entire guide rail.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] (1) Using the intermittent push-type scraping mechanism and the self-dumping collection mechanism, during the closing process of the skylight, the scraper moves forward and pushes the impurities in the sliding groove, and uses the bristles to clean the dust. When the skylight is completely closed, the scraper also moves to the front of the sliding groove, and the impurities can be pushed into the collection box for collection, so that the impurities inside the sliding groove can be cleaned, avoiding the impurities increasing the friction between the pulley and the inner wall of the sliding groove, and even large pieces of foreign matter are directly stuck between the pulley and the sliding groove, ensuring the normal opening and closing of the skylight. In addition, during the movement of the scraper, the bonding plate will cut into When the impurities are in contact with the inner wall of the sliding groove, the impurities in contact with the inner walls of the two sides of the sliding groove are shoveled between the two scraper plates 2 to separate the impurities from the inner walls of the two sides of the sliding groove. Then, the impurities are pushed by the scraper plate 1, which can prevent some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., from being squeezed or cut against the inner wall of the sliding groove when being pushed, causing the inner wall of the sliding groove to be scratched, thereby shortening the service life of the entire guide rail. In addition, when the cross bar moves, it will intermittently pass through a plurality of protrusions, which make the slider intermittently rise, so that the connecting rods 3 on both sides can rotate in different directions at the same time to drive the The scrapers slide in different directions and approach each other at the same time, so as to push the impurities further away from the inner wall of the sliding groove, and prevent the impurities from being scratched by the inner wall of the sliding groove due to the end of the impurities still being in contact with the inner wall of the sliding groove after being scooped up by the bonding plate due to being too long. In addition, when the two scrapers approach each other, the bonding plate will always be in contact with the inner wall of the sliding groove under the action of the spring two, and the impurities will not enter between the scrapers and the inner wall of the sliding groove when the two scrapers approach each other. When the impurities are all in the collection box and have accumulated to a certain amount, the skylight can be opened again. At this time, the connecting rods one and two are driven to rotate. , so that the collecting box rises, and drives the collecting box to rotate, so that the collecting box always remains straight, and drives the cover plate to rotate to cover the top of the collecting box to prevent the collected impurities from accidentally falling into the car. When the collecting box rises to a certain height, the rotating block is driven to rotate again, so that the collecting box is located outside the roof of the car, and the collecting box is driven to rotate by motor 2 again, so that the impurities collected in the collecting box can be poured out, thereby realizing self-cleaning of the impurities collected in the collecting box, ensuring the subsequent use effect of the collecting box, and eliminating the process of manual cleaning of the impurities inside the collecting box, which is more convenient.

[0021] (2) When it rains, the sunroof is closed. However, there is still a gap between the sunroof and the roof, and rainwater may still flow into the sliding groove. In order to avoid the adverse effects caused by water accumulation in the sliding groove, when rainwater is in the sliding groove, it will flow into the drainage pipe inside the car through the drain port and filter 1, and then be discharged outside the car, thereby achieving the drainage effect, avoiding the situation where water is retained in the sliding groove and then seeping into the car, causing the interior to get damp and moldy, and even affecting the normal operation of the vehicle's electrical system. In addition, filter 2 and filter 1 can be used to filter impurities in the sliding groove, avoiding the situation where impurities block the drain port and the drainage pipe inside the car, thereby ensuring the normal drainage work.

[0052] Specifically, a car sunroof is a glass or transparent plastic plate structure installed on the top of a vehicle to increase the light inside the car and improve the ventilation effect, and a car sunroof guide rail is a device installed on the roof of the car to control the opening and closing of the roof sunroof. It is a key component in the sunroof assembly and has an important impact on the normal operation and life of the sunroof. When the existing car sunroof guide rail is in use, the pulley 20 slides inside the sliding groove 2 of the guide rail frame 1 to drive the sunroof glass module to move and realize the opening and closing of the sunroof. However, when the sunroof is opened, external impurities Impurities such as stones and sand may enter the sliding groove 2. When there are impurities inside the sliding groove 2, the friction between the pulley 20 and the inner wall of the sliding groove 2 will increase, and even large foreign objects may be directly stuck between the pulley 20 and the sliding groove 2, thereby affecting the normal opening and closing of the skylight. In addition, for some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., they may be squeezed or cut against the inner wall of the sliding groove 2 under the push of the pulley 20, causing the inner wall of the sliding groove 2 to be scratched, thereby shortening the service life of the entire guide rail.

[0053] Therefore, in order to solve the above problems, when this embodiment is used, the guide rail frame 1 is installed on the top of the car by using the multiple mounting holes on the guide rail frame 1, and the sunroof module is installed on the cross bars 3 on both sides by using the threaded hole 1 4 and the threaded hole 2 5. The sunroof module can be driven to move by the driving device. The driving device is an existing device that can cooperate with the guide rail assembly and there is no need to elaborate on it. At the same time, the pulley 20 slides inside the sliding groove 2 to realize the opening and closing of the sunroof.

[0054] Due to the shielding effect of the skylight, when the skylight is opened, impurities such as stones will only be concentrated on the front side of the sliding groove 2, and will not be between the pulleys 20 on the front and rear sides. Therefore, when the skylight is opened and causes impurities such as stones and sand to accumulate in the sliding groove 2, the skylight is driven to close. When the skylight is closed, the cross bar 3 moves forward, and the scraper 24 is used to push the impurities in the sliding groove 2, and the bristles 25 are used to clean the dust. After the skylight is completely closed, the scraper 24 also moves to the front of the sliding groove 2, and the impurities can be pushed into the collection box 12 for collection, thereby realizing the cleaning of the impurities inside the sliding groove 2, avoiding the impurities increasing the friction between the pulley 20 and the inner wall of the sliding groove 2, and even avoiding the situation where large foreign objects are directly stuck between the pulley 20 and the sliding groove 2, thereby ensuring the normal opening and closing of the skylight.

[0055] In addition, in order to prevent the impurities from scratching the inner wall of the sliding groove 2 when being pushed by the scraper 1 24, when the scraper 1 24 moves, since the scraper 2 30 and the bonding plate 31 are bonded to the inner wall of the sliding groove 2, the bonding plate 31 will cut into the bonding point between the impurities and the inner wall of the sliding groove 2 to shovel the impurities bonded to the inner walls on both sides of the sliding groove 2 into between the two scraper 2 30, so that the impurities are separated from the inner walls on both sides of the sliding groove 2. Then the impurities are pushed by the scraper 1 24 again, which can prevent some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., from being squeezed or cut against the inner wall of the sliding groove 2 when being pushed, causing the inner wall of the sliding groove 2 to be scratched, thereby shortening the service life of the entire guide rail. In addition, although the bonding plate 31 can separate the impurities from the inner walls on both sides of the sliding groove 2, if the impurities are long, such as branches, their ends may still contact the inner walls on both sides of the sliding groove 2, and the inner wall of the sliding groove 2 may still be scratched. After the lifting block 22 passes the protrusion 7, it will be restored under the action of the spring 1 26, so that the impurities can be pushed many times.

[0056] When the impurities are all in the collecting box 12 and have accumulated to a certain amount, the sunroof can be opened again. At this time, the connecting rod 1 8 and the connecting rod 2 10 are no longer blocked, and then the motor 3 13 is used to drive the connecting rod 1 8 to rotate, and the motor 1 9 drives the connecting rod 2 10 to rotate, so that the collecting box 12 rises, and the motor 2 11 is used to drive the collecting box 12 to rotate, so that the collecting box 12 always remains straight, and the motor 5 19 is used to drive the cover plate 18 to rotate to cover the top of the collecting box 12 to prevent the collected impurities from accidentally falling into the car. When the collecting box 12 rises to a certain height, the motor 4 15 is used again to drive the rotating block 14 to rotate ninety degrees, so that the collecting box 12 is located outside the roof of the car, and the motor 2 11 is used again to drive the collecting box 12 to rotate, so that the impurities collected in the collecting box 12 can be dumped out, thereby realizing self-cleaning of the impurities collected in the collecting box 12, ensuring the subsequent use effect of the collecting box 12, and also eliminating the need for personnel to manually clean the impurities in the collecting box 12, which is more convenient.

[0057] Thus, by utilizing the intermittent push-type scraping mechanism and the self-dumping type collecting mechanism, during the closing process of the skylight, the scraper 24 moves forward and pushes the impurities in the sliding groove 2, and uses the bristles 25 to clean the dust. After the skylight is completely closed, the scraper 24 also moves to the front of the sliding groove 2, and the impurities can be pushed into the collecting box 12 for collection, thereby realizing the cleaning of the impurities inside the sliding groove 2, avoiding the impurities increasing the friction between the pulley 20 and the inner wall of the sliding groove 2, and even preventing large foreign objects from being directly stuck between the pulley 20 and the sliding groove 2, thereby ensuring the normal opening and closing of the skylight. In addition, during the movement of the scraper 24, the bonding plate 31 will cut into the impurities. The impurities that are in contact with the inner walls of the sliding groove 2 are shoveled between the two scraper plates 2 30 to separate the impurities from the inner walls of the sliding groove 2. Then, the impurities are pushed by the scraper plates 24, which can prevent some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., from squeezing or cutting the inner wall of the sliding groove 2 when being pushed, causing the inner wall of the sliding groove 2 to be scratched, thereby shortening the service life of the entire guide rail. In addition, when the cross bar 3 moves, it will intermittently pass through multiple protrusions 7, and the protrusions 7 will make the slider 28 rise intermittently, so that the connecting rods 3 29 on both sides can rotate in different directions at the same time, so as to drive the scraper plates 2 30 on both sides to move non-stop at the same time. By sliding in the same direction and approaching each other, the impurities can be pushed further away from the inner wall of the sliding groove 2, so as to prevent the impurities from being too long and being scooped up by the bonding plate 31, and the end of the impurities still being in contact with the inner wall of the sliding groove 2, thereby scratching the inner wall of the sliding groove 2. In addition, when the two scrapers 30 are close to each other, the bonding plate 31 will always be in contact with the inner wall of the sliding groove 2 under the action of the spring 2 32, and the impurities will not enter between the scrapers 30 and the inner wall of the sliding groove 2 when the two scrapers 30 are close to each other. When the impurities are all behind the collection box 12 and have accumulated to a certain amount, the skylight can be opened again. At this time, the connecting rod 1 8 and the connecting rod 2 10 are driven to rotate, so that the collection box 1 2 rises, and drives the collection box 12 to rotate, so that the collection box 12 always remains straight, and drives the cover plate 18 to rotate to cover the top of the collection box 12 to prevent the collected impurities from accidentally falling into the car. When the collection box 12 rises to a certain height, the rotating block 14 is driven to rotate again, so that the collection box 12 is located outside the roof of the car, and the collection box 12 is driven to rotate by the motor 2 11 again, so that the impurities collected in the collection box 12 can be dumped out, thereby realizing the self-cleaning of the impurities collected in the collection box 12, ensuring the subsequent use effect of the collection box 12, and also eliminating the process of manual cleaning of the impurities in the collection box 12 by personnel, which is more convenient.

[0058] like Fig.11As shown, in this embodiment, a filter screen 2 33 is provided on the drain outlet 34, and a filter screen 17 is provided at the bottom of the collection box 12. After the water in the sliding groove 2 passes through the filter screen 17 and the drain outlet 34, it will flow into the drainage pipe inside the car and be discharged outside the car.

[0059] Specifically, when it rains, the sunroof is in a closed state, but there is still a gap between the sunroof and the roof, and rainwater may still flow into the sliding groove 2. In order to avoid the adverse effects caused by water accumulation in the sliding groove 2, when the rainwater is in the sliding groove 2, it will flow into the drainage pipe inside the car through the drain port 34 and the filter screen 17, and be discharged outside the car, thereby achieving the drainage effect, avoiding the accumulation of water in the sliding groove 2 and then seeping into the car, causing the interior to become damp and moldy, and even affecting the normal operation of the vehicle's electrical system. In addition, the filter screen 2 33 and the filter screen 17 can be used to filter impurities in the sliding groove 2, avoiding the situation where impurities block the drain port 34 and the drainage pipe inside the car, thereby ensuring the normal drainage work.

[0060] The working principle of the present application is as follows: the guide rail frame is mounted on the top of the car by using a plurality of mounting holes on the guide rail frame, and the sunroof module is mounted on the cross bars on both sides by using threaded hole 1 and threaded hole 2, and the sunroof module can be driven to move by a driving device, and the driving device is an existing device that can cooperate with the guide rail assembly, and there is no need to elaborate on it. At the same time, the pulley slides inside the sliding groove to realize the opening and closing of the sunroof; when it rains, the sunroof is in a closed state, but there is still a gap between the sunroof and the roof, and rainwater may still flow into the sliding groove. In order to avoid adverse effects caused by accumulated water being retained in the sliding groove, when rainwater is in the sliding groove, it will flow into the drainage pipe inside the car through the drain port and the filter screen 1, and be discharged outside the car, thereby achieving a drainage effect, avoiding the situation where accumulated water is retained inside the sliding groove and then seeping into the car, causing the interior to be damp and moldy, and even affecting the normal operation of the vehicle's electrical system, and, The filter screen 2 and the filter screen 1 can filter the impurities inside the sliding groove to avoid the situation that the impurities block the drain outlet and the drainage pipe inside the car, thereby ensuring the normal drainage work; due to the shielding effect of the sunroof, when the sunroof is opened, impurities such as stones will only be concentrated on the front side of the sliding groove, and will not be between the pulleys on the front and rear sides. Therefore, when the sunroof is opened and causes the accumulation of impurities such as stones and sand in the sliding groove, the sunroof is driven to close. When the sunroof is closed, the cross bar moves forward, and the scraper 1 is used to push the impurities in the sliding groove, and the dust is cleaned with the bristles. After the sunroof is completely closed, the scraper 1 also moves to the front of the sliding groove, and the impurities can be pushed into the collection box for collection, thereby realizing the cleaning of the impurities inside the sliding groove, avoiding the impurities increasing the friction between the pulley and the inner wall of the sliding groove, and even the situation that large foreign objects are directly stuck between the pulley and the sliding groove, thereby ensuring the normal opening and closing of the sunroof;Furthermore, in order to prevent the impurities from scratching the inner wall of the sliding groove when being pushed by the scraper one, when the scraper one moves, since the scraper two and the bonding plate are bonded to the inner wall of the sliding groove, the bonding plate will cut into the bonding point between the impurities and the inner wall of the sliding groove to shovel the impurities bonded to the inner walls on both sides of the sliding groove into between the two scraper twos, so that the impurities are separated from the inner walls on both sides of the sliding groove. Then the impurities are pushed by the scraper one again, which can prevent some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., from being squeezed or cut against the inner wall of the sliding groove when being pushed, causing the inner wall of the sliding groove to be scratched, thereby shortening the service life of the entire guide rail. Moreover, although the laminating plate can separate the impurities from the inner walls on both sides of the sliding groove, if the impurities are long, such as branches, their ends may still contact the inner walls on both sides of the sliding groove, and the inner walls of the sliding groove may be scratched. Therefore, when the cross bar moves, it will intermittently pass through multiple protrusions, and the lifting block will come into contact with the protrusions. The lifting block rises with the rise and fall of the protrusions, the sliding bar slides, and the sliding block rises, so that the connecting rods on both sides can rotate in different directions at the same time, so as to drive the scrapers on both sides to slide in different directions at the same time and approach each other, so as to push the impurities and make them further away from the inner wall of the sliding groove, so as to prevent the impurities from being laminating due to being too long. After the plate is scooped up, its end portion still fits the inner wall of the sliding groove and scratches the inner wall of the sliding groove. Moreover, when the two scraper plates 2 are close to each other, the fitting plate will always fit the inner wall of the sliding groove under the action of the spring 2, and the impurities will not enter between the scraper plates 2 and the inner wall of the sliding groove when the two scraper plates 2 are close to each other. When the lifting block passes the convex block, it will be restored under the action of the spring 1, so that the impurities can be pushed multiple times. When the impurities are all behind the collection box and accumulate to a certain amount, the skylight can be opened again. At this time, the connecting rod 1 and the connecting rod 2 are no longer blocked, and then the motor 3 is used to drive the connecting rod 1 to rotate, and the motor 1 drives the connecting rod 2 to rotate, so that the collection box The collecting box rises, and the collecting box is driven to rotate by the second motor, so that the collecting box always remains straight, and the cover plate is driven to rotate by the fifth motor to cover the top of the collecting box to prevent the collected impurities from accidentally falling into the car. When the collecting box rises to a certain height, the rotating block is driven to rotate 90 degrees by the fourth motor again, so that the collecting box is located outside the roof of the car, and the collecting box is driven to rotate by the second motor again, so that the impurities collected in the collecting box can be dumped out, thereby realizing the self-cleaning of the impurities collected in the collecting box, ensuring the subsequent use effect of the collecting box, and also eliminating the process of manual cleaning of the impurities in the collecting box by personnel, which is more convenient.Therefore, by utilizing the intermittent push-type scraping mechanism and the self-dumping type collecting mechanism, during the closing process of the skylight, the scraper 1 moves forward and pushes the impurities in the sliding groove, and uses the bristles to clean the dust. When the skylight is completely closed, the scraper 1 also moves to the front of the sliding groove, and can push the impurities into the collecting box for collection, thereby realizing the cleaning of the impurities inside the sliding groove, avoiding the impurities increasing the friction between the pulley and the inner wall of the sliding groove, and even preventing large foreign objects from being directly stuck between the pulley and the sliding groove, thereby ensuring the normal opening and closing of the skylight. In addition, during the movement of the scraper 1, the bonding plate will cut into The impurities that fit with the inner walls of the sliding groove are shoveled between the two scraper plates 2 to separate the impurities from the inner walls of the sliding groove. Then, the impurities are pushed by the scraper plate 1, which can prevent some materials with sharp edges or high hardness, such as pebbles, metal fragments, etc., from squeezing or cutting the inner wall of the sliding groove when being pushed, causing the inner wall of the sliding groove to be scratched, thereby shortening the service life of the entire guide rail. In addition, when the cross bar moves, it will intermittently pass through multiple protrusions, which make the slider rise intermittently, so that the connecting rods 3 on both sides can rotate in different directions at the same time to drive the scrapers on both sides. The two plates slide in different directions and approach each other at the same time, so as to push the impurities further away from the inner wall of the sliding groove, thereby preventing the impurities from being scratched by the inner wall of the sliding groove due to their too long length and the end of the impurities still adhering to the inner wall of the sliding groove after being scooped up by the bonding plate. In addition, when the two scraper plates approach each other, the bonding plate will always be in contact with the inner wall of the sliding groove under the action of the spring two, and the impurities will not enter between the scraper plates and the inner wall of the sliding groove when the two scraper plates approach each other. When the impurities are all in the collection box and have accumulated to a certain amount, the skylight can be opened again. At this time, the connecting rods one and two are driven to rotate. The collection box is raised and driven to rotate, so that the collection box always remains straight, and the cover is driven to rotate to cover the top of the collection box to prevent the collected impurities from accidentally falling into the car. When the collection box rises to a certain height, the rotating block is driven to rotate again, so that the collection box is located outside the roof of the car, and the collection box is driven to rotate by the second motor again, so that the impurities collected in the collection box can be dumped out, thereby realizing the self-cleaning of the impurities collected in the collection box, ensuring the subsequent use effect of the collection box, and also eliminating the process of manual cleaning of the impurities in the collection box by personnel, which is more convenient. ;
