Description

Technical Field

[0001] The present invention relates to the technical field of automotive interior sealing, and particularly to a sealing structure for an automotive interior ceiling. Background Art

[0002] The so-called automotive interior mainly refers to automotive products used for internal modification of automobiles, covering all aspects inside the automobile. Among them, the automotive interior ceiling is an important part of the entire automotive interior. It covers the roof sheet metal, reduces and lowers the noise and heat conduction inside and outside the automobile, and provides a certain degree of safety protection for the heads of the driver and passengers.

[0003] Patent Publication No. CN212709254U discloses a sealing structure for an automotive interior ceiling, including an interior ceiling, a sealing structure is installed on the outer wall surface of the interior ceiling, a roof structure is installed on the upper wall surface of the sealing structure, and a screw structure is installed on the inner wall surface of the interior ceiling; the sealing structure includes: a sealing outer wall, a sealing strip, and a sealing inner wall; the sealing outer wall is installed on the outer wall surface of the interior ceiling, the sealing strip is installed on the inner wall surface of the sealing outer wall, and the sealing inner wall is installed on the inner wall surface of the sealing strip. Compared with the traditional automotive interior ceiling, by adding a sealing structure on the outer wall surface of the automotive interior ceiling, the sealing strip can prevent water or dust from entering the gap between the interior ceiling and the roof, which can reduce the wear of the automobile, improve the reliability of the automobile, reduce potential safety hazards, reduce the number of repairs and repair costs. At the same time, the structure is simple, easy to manufacture and install, and has a low cost, and has a wide range of applications.

[0004] The sealing structure in the above device realizes the functions of waterproofing and dust prevention, but its overall sealing structure is relatively simple, and the sealing protection is carried out through the set sealing strip. However, on this basis, the interior ceiling and the roof are only connected and fixed by screws. Such a fixing method cannot ensure that each position of the sealing strip can maintain good fit with the roof. Especially as the sealing strip ages, if the distance between the fixing position of the sealing strip and the screw is far, there is a high possibility that the contact surface between the sealing strip and the roof is separated, resulting in a decrease in sealing performance. Therefore, a sealing structure for an automotive interior ceiling is proposed here to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned problems, the present invention provides a sealing structure for an automotive interior ceiling.

[0006] The sealing structure for an automotive interior ceiling provided by the present invention adopts the following technical solutions:

[0007] A sealing structure for an automotive interior ceiling, comprising a vehicle roof and an interior ceiling panel. The interior ceiling panel is disposed at the bottom of the vehicle roof. An insertion plate is integrally formed at the bottom of the vehicle roof. An insertion slot is formed at the top of the interior ceiling panel. The insertion plate extends into the interior of the insertion slot and matches the insertion slot. A sealing mechanism is provided on the interior ceiling panel;

[0008] The sealing mechanism includes a sealing strip. The sealing strip is disposed inside the insertion slot and matches the insertion slot. The sealing strip is in contact with the bottom of the insertion plate. Four long plates are provided on the inner side of the interior ceiling panel. A fixing plate is integrally formed on one side of the long plate. The fixing plate extends into the interior of the insertion slot. A fixing groove is formed on the insertion plate. The fixing plate extends into the interior of the fixing groove and matches the fixing groove.

[0009] By adopting the above technical solution, when splicing the vehicle roof and the interior ceiling panel, the insertion plate on the vehicle roof enters the interior of the insertion slot and abuts against the sealing strip after entering, thereby ensuring the sealing performance at the joint after the two are installed. On this basis, after controlling the movement of the long plate, the fixing plate on one side of the long plate is inserted into the fixing groove on the insertion plate. By fixing the insertion plate through multiple fixing plates, different positions of the insertion plate can be stably attached to the sealing strip, thereby ensuring the sealing quality and the durability of the sealing performance.

[0010] Preferably, the four long plates are symmetrically distributed in a rectangular shape on the inner side of the interior ceiling panel, and the fixing plates are arranged at equal intervals on one side of the long plate.

[0011] By adopting the above technical solution, after the long plates are symmetrically distributed in a rectangular shape on the inner side of the interior ceiling panel, the four side walls of the insertion plate can be limited, and multiple fixing plates can ensure that different areas and positions of the insertion plate are closely attached to the sealing strip.

[0012] Preferably, a limiting plate is fixedly connected to the inner side wall of the interior ceiling panel. The limiting plate penetrates the long plate, and a first spring piece is fixedly connected to the long plate.

[0013] By adopting the above technical solution, the limiting plate limits the long plate to ensure stable horizontal movement of the long plate.

[0014] Preferably, the first spring piece is disposed inside the limiting plate and is fixedly connected to the limiting plate.

[0015] By adopting the above technical solution, the first spring piece exerts an elastic force on the long plate, and this elastic force can push the long plate away from the insertion plate.

[0016] Preferably, the sealing mechanism includes a control component. The control component includes a trapezoidal control plate. Two limit telescopic rods are fixedly connected to the bottom of the trapezoidal control plate. One end of each of the two limit telescopic rods is fixedly connected to the inner side of the interior ceiling board. A trapezoidal groove is formed inside the long board. A threaded adjusting rod is rotatably connected to the bottom of the trapezoidal control plate. A groove is formed in the bottom of the interior ceiling board. The threaded adjusting rod extends into the groove. The threaded adjusting rod is threadedly connected to the interior ceiling board. A frame plate is fixedly connected to the bottom of the interior ceiling board. The frame plate is arranged on one side of the groove. A sealing cover is arranged at the bottom of the interior ceiling board. The sealing cover extends into the groove and matches the groove.

[0017] By adopting the above technical solution, the limit telescopic rods vertically limit the trapezoidal control plate to ensure that the trapezoidal control plate moves vertically up and down without deviation. The trapezoidal control plate can move up and down inside the trapezoidal groove and squeeze the inclined walls inside the trapezoidal groove during the movement to form a pushing effect.

[0018] Preferably, the threaded adjusting rod is arranged between the two limit telescopic rods, and the trapezoidal control plate is in contact with the inner side of the trapezoidal groove.

[0019] By adopting the above technical solution, after the threaded adjusting rod rotates, it can drive the trapezoidal control plate to move up and down.

[0020] Preferably, a cross groove is formed in the bottom of the threaded adjusting rod. A cross inserting plate is integrally formed on the sealing cover. The cross inserting plate extends into the cross groove and matches the cross groove. A strip plate is integrally formed on the bottom of the sealing cover.

[0021] By adopting the above technical solution, when the sealing cover is closed inside the groove, after the cross inserting plate on the sealing cover is inserted into the cross groove at the bottom of the threaded adjusting rod, rotating the sealing cover can control the threaded adjusting rod to rotate. The strip plate is provided for the user to hold and manipulate.

[0022] Preferably, an extension plate is slidably connected to the inner side of the frame plate. The extension plate extends out of the frame plate. A limiting groove is formed in the sealing cover. The extension plate extends into the limiting groove and matches the limiting groove. A second spring piece is fixedly connected to the inside of the frame plate. The second spring piece is fixedly connected to one side of the extension plate.

[0023] By adopting the above technical solution, after the extension plate enters the limiting groove, it limits the sealing cover. The sealed cover after being limited cannot rotate, so as to improve the stability of the sealing cover inserted into the groove. The second spring piece has an elastic force on the extension plate to push the extension plate out of the frame plate.

[0024] Preferably, an auxiliary plate is fixedly connected to the bottom of the extension plate, and anti-slip grooves are formed in the auxiliary plate and are arranged at equal intervals on the auxiliary plate.

[0025] By adopting the above technical solution, the staff can control the movement of the extension plate by pushing the auxiliary plate, and the anti-slip grooves on the extension plate can play an anti-slip role to improve the stability during the pushing process.

[0026] In summary, the present invention includes the following beneficial technical effects:

[0027] 1. A sealing structure for an automobile interior ceiling. Through the design of the sealing mechanism, when splicing the vehicle roof and the interior ceiling board, the plug-in board on the vehicle roof enters the plug-in groove and abuts against the sealing strip after entering, so as to ensure the sealing performance at the joint after the two are installed. On this basis, after controlling the movement of the long board, the fixing plate on one side of the long board is inserted into the fixing groove on the plug-in board, and the plug-in board is fixed by a plurality of fixing plates, so as to ensure that different positions of the plug-in board can be stably attached to the sealing strip, thereby ensuring the sealing quality and the durability of the sealing performance.

[0028] 2. A sealing structure for an automobile interior ceiling. Through the design of the control component, the purpose of controlling the movement of the long board can be achieved by rotating the threaded adjusting rod. And on this basis, the setting of the sealing cover can provide external protection for the threaded adjusting rod to prevent external oil, sewage, stains and other impurities from rusting the threaded adjusting rod, so as to ensure the service life of the threaded adjusting rod. Secondly, the threaded adjusting rod can also be directly rotated through the sealing cover, thereby reducing the operation threshold. Compared with the need to rely on tools for installation, the operation is more flexible and convenient.

[0029] 3. A sealing structure for an automobile interior ceiling realizes the convenient installation of the automobile interior ceiling board and ensures the stability of the sealing performance after installation. On the basis of realizing the above functions, its structure design is simple, which is more conducive to production and manufacturing and cost control, and is more suitable for popularization and use.

Detailed implementation manners

[0041] The following further describes the present invention in detail with reference to the attached Figure 1 - attached Figure 10 drawings.

[0042] The present invention discloses a sealing structure for an interior ceiling of an automobile. Referring to Figures 1 - 10 , it includes a car roof 1 and an interior ceiling panel 2. The interior ceiling panel 2 is arranged at the bottom of the car roof 1. A plug-in board 3 is integrally formed at the bottom of the car roof 1. A plug-in slot 4 is opened at the top of the interior ceiling panel 2. The plug-in board 3 extends into the interior of the plug-in slot 4 and matches the plug-in slot 4. A sealing mechanism 5 is arranged on the interior ceiling panel 2;

[0043] The sealing mechanism 5 includes a sealing strip 51. The sealing strip 51 is arranged inside the insertion slot 4 and matches the insertion slot 4. The sealing strip 51 is in contact with the bottom of the insertion plate 3. Four long plates 52 are arranged on the inner side of the interior ceiling panel 2. A fixing plate 53 is integrally formed on one side of the long plate 52. The fixing plate 53 extends into the insertion slot 4. A fixing groove 54 is formed on the insertion plate 3. The fixing plate 53 extends into the fixing groove 54 and matches the fixing groove 54. When splicing the vehicle roof 1 and the interior ceiling panel 2, the insertion plate 3 on the vehicle roof 1 enters the insertion slot 4 and abuts against the sealing strip 51 after entering, so as to ensure the sealing performance at the joint after the two are installed. On this basis, after controlling the movement of the long plate 52, the fixing plate 53 on one side of the long plate 52 is inserted into the fixing groove 54 on the insertion plate 3. By fixing the insertion plate 3 with multiple fixing plates 53, different positions of the insertion plate 3 can be kept in stable contact with the sealing strip 51, so as to ensure the sealing quality and the durability of the sealing performance.

[0044] The four long plates 52 are symmetrically distributed in a rectangular shape on the inner side of the interior ceiling panel 2. The fixing plates 53 are arranged at equal intervals on one side of the long plate 52. After the long plates 52 are symmetrically distributed in a rectangular shape on the inner side of the interior ceiling panel 2, the four side walls of the insertion plate 3 can be limited. The multiple fixing plates 53 can make different area positions of the insertion plate 3 keep close contact with the sealing strip 51. A limiting plate 55 is fixedly connected to the inner side wall of the interior ceiling panel 2. The limiting plate 55 penetrates the long plate 52. A first spring piece 56 is fixedly connected to the long plate 52. The limiting plate 55 limits the long plate 52 to ensure the stable horizontal movement of the long plate 52. The first spring piece 56 is arranged inside the limiting plate 55 and is fixedly connected to the limiting plate 55. The first spring piece 56 has an elastic force on the long plate 52, and this elastic force can push the long plate 52 in the direction away from the insertion plate 3.

[0045] The sealing mechanism 5 includes a control component. The control component includes a trapezoidal control board 57. Two limit telescopic rods 58 are fixedly connected to the bottom of the trapezoidal control board 57. One end of each of the two limit telescopic rods 58 is fixedly connected to the inner side of the interior ceiling board 2. A trapezoidal groove 59 is formed inside the long board 52. A threaded adjustment rod 591 is rotatably connected to the bottom of the trapezoidal control board 57. A groove 593 is formed at the bottom of the interior ceiling board 2. The threaded adjustment rod 591 extends into the groove 593. The threaded adjustment rod 591 is threadedly connected to the interior ceiling board 2. A frame board 592 is fixedly connected to the bottom of the interior ceiling board 2. The frame board 592 is arranged on one side of the groove 593. A sealing cover 594 is arranged at the bottom of the interior ceiling board 2. The sealing cover 594 extends into the groove 593 and matches the groove 593. The limit telescopic rods 58 vertically limit the trapezoidal control board 57 to ensure that the trapezoidal control board 57 moves vertically up and down without deviation. The trapezoidal control board 57 can move up and down inside the trapezoidal groove 59 and squeeze the inclined walls inside the trapezoidal groove 59 during the movement to form a pushing effect;

[0046] The threaded adjustment rod 591 is arranged between the two limit telescopic rods 58. The trapezoidal control board 57 is in contact with the inner side of the trapezoidal groove 59. After the threaded adjustment rod 591 rotates, it can drive the trapezoidal control board 57 to move up and down. A cross groove 595 is formed at the bottom of the threaded adjustment rod 591. A cross insertion plate 596 is integrally formed on the sealing cover 594. The cross insertion plate 596 extends into the cross groove 595 and matches the cross groove 595. A strip plate is integrally formed at the bottom of the sealing cover 594. When the sealing cover 594 covers the groove 593, after the cross insertion plate 596 on the sealing cover 594 is inserted into the cross groove 595 at the bottom of the threaded adjustment rod 591, rotating the sealing cover 594 can control the rotation of the threaded adjustment rod 591. The strip plate is provided for the user to hold and control.

[0047] An extension plate 597 is slidably connected to the inner side of the frame plate 592. The extension plate 597 extends outside the frame plate 592. A limiting groove 598 is formed in the sealing cover 594. The extension plate 597 extends into the limiting groove 598 and matches the limiting groove 598. A second spring piece 599 is fixedly connected inside the frame plate 592. The second spring piece 599 is fixedly connected to one side of the extension plate 597. After the extension plate 597 enters the limiting groove 598, the sealing cover 594 is limited, and the sealed cover 594 after being limited cannot rotate, so as to improve the stability after the sealing cover 594 is inserted into the groove 593. The second spring piece 599 has an elastic force on the extension plate 597, so as to push the extension plate 597 out of the frame plate 592. An auxiliary plate 581 is fixedly connected to the bottom of the extension plate 597. Anti-slip grooves are formed in the auxiliary plate 581. The anti-slip grooves are arranged at equal intervals on the auxiliary plate 581. The staff can control the movement of the extension plate 597 by pushing the auxiliary plate 581. The anti-slip grooves on the extension plate 597 can play an anti-slip role to improve the stability during the pushing process.

[0048] During the actual operation process, when it is necessary to assemble and join the vehicle roof 1 and the interior ceiling board 2, directly align the insertion slot 4 on the interior ceiling board 2 with the insertion board 3 and then insert and join them. At this time, the insertion board 3 enters the insertion slot 4. The elastic force of the first spring piece 56 on the long board 52 can push the long board 52 in the direction away from the insertion slot 4, so as to prevent the fixing plate 53 from obstructing the insertion of the insertion board 3 when it is inside the insertion slot 4. When the insertion board 3 is tightly inserted into the insertion slot 4, at this time, the insertion board 3 presses the sealing strip 51 tightly inside the insertion slot 4, so as to ensure the sealing performance after the connection between the vehicle roof 1 and the interior ceiling board 2;

[0049] After the vehicle roof 1 and the interior ceiling board 2 are spliced as above, the cross insertion board 596 on the sealing cover 594 can be inserted into the cross slot 595, and then the sealing cover 594 is rotated. The sealing cover 594 drives the threaded adjustment rod 591 to rotate. After the threaded adjustment rod 591 rotates, it moves up and down. After the threaded adjustment rod 591 moves, it drives the trapezoidal control plate 57 to move. After the trapezoidal control plate 57 moves, it presses against the inclined side wall of the trapezoidal groove 59. During the continuous rising process, an extrusion and pushing effect on the long board 52 is formed. The long board 52 drives the fixing plate 53 to move until the fixing plate 53 is completely inserted into the fixing slot 54, and a locking effect on the insertion board 3 is formed. At this time, the interior ceiling board 2 is stably installed on the vehicle roof 1;

[0050] Before rotating the control threaded adjusting rod 591, pull the extension plate 597 on one side of the threaded adjusting rod 591 to the inside of the frame plate 592 to avoid obstruction of the installation of the threaded adjusting rod 591 by the extension plate 597. When the threaded adjusting rod is fully screwed in, insert the sealing cover 594 into the groove 593. During the insertion process, ensure that the cross insertion plate 596 is aligned with the cross groove 595 and inserted therein. Subsequently, after the sealing cover 594 is installed, the limiting groove 598 on the sealing cover 594 is aligned with one side of the extension plate 597. At this time, stop pulling the extension plate 597, and the elastic force of the second reed 599 pushes the extension plate 597 out to be inserted into the limiting groove 598. There is friction between the extension plate 597 and the inner side of the limiting groove 598, which can further improve the stability after the installation of the sealing cover 594. Moreover, the extension plate 597 can also prevent the sealing cover 594 from rotating due to external factors, thereby causing the threaded adjusting rod 591 to rotate and the fixing plate 53 to leave the fixing groove 54, resulting in loosening of the installation of the interior ceiling panel 2, effectively improving the stability after installation.

[0051] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
