Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a roof interior canopy connection assembly for a commercial vehicle. Background Technology

[0002] Existing methods for connecting automotive interior headliners to the roof mostly use clips. However, this method is not suitable for headliner materials that are soft or thick. To address this issue, Chinese utility model patent application number 202420797350.4 discloses a connecting assembly for the interior headliner of a commercial vehicle. This assembly uses a connecting mechanism that works with mating holes in the roof to secure the interior headliner. However, this connecting mechanism includes pressing components, spring components, clips, and other parts, resulting in a complex and cumbersome design. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the aforementioned background technology by providing a commercial vehicle roof interior canopy connection assembly that is simple in structure, stable in connection, and convenient and efficient in disassembly and assembly.

[0004] To achieve the above objectives, this utility model provides a roof interior canopy connection assembly for a commercial vehicle, which adopts the following technical solution:

[0005] A roof lining connection assembly for a commercial vehicle is disclosed, used to connect the interior roof lining to the roof of the commercial vehicle. The assembly includes a connector passing through the interior roof lining. The connector includes a cylindrical fixing member with a cuboid protrusion on its upper surface and a groove on its lower surface. A fixing groove communicating with the groove is provided on the outer wall of the fixing member. A limiting plate is provided at the fixing groove, with its upper end rotatably connected to the upper part of the fixing groove. An adjusting plate is provided within the groove to abut against the limiting plate and cause it to expand outwards. The lower end of the adjusting plate is connected to a cover plate via a connecting rod. A surrounding plate is provided on the periphery of the cover plate, with threads on the lower part of the surrounding plate and the fixing member. The surrounding plate is screwed to the lower part of the fixing member. The fixing member also passes through a pressure plate, with the upper end of the surrounding plate abutting against the pressure plate.

[0006] A further improvement of this utility model to the roof interior canopy connection assembly of a commercial vehicle is that the adjustment plate includes a frustum-shaped adjustment part that gradually increases in size from top to bottom.

[0007] A further improvement of this utility model to the roof interior canopy connection assembly of a commercial vehicle is that the fixing groove and the limiting plate are provided in four sets, which are evenly distributed.

[0008] A further improvement of this utility model to the roof interior canopy connection assembly of a commercial vehicle is that a pull wire is connected below the limiting plate.

[0009] A further improvement of this utility model regarding the connection assembly of the interior roof of a commercial vehicle is that the protruding part is cubic in shape and is used to fit the mating holes arranged on the roof. The lower end face of the mating hole is provided with a horizontally arranged ring plate, the fixing member passes through the ring plate, and the limiting plate protrudes and abuts against the ring plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model simplifies the connection structure. The limiting plate can be moved outward by adjusting the plate, and then the limiting and fixing can be achieved by cooperating with the mating hole. At the same time, the connection structure of the adjusting plate also limits the pressure plate, thereby ensuring the connection stability of the interior headliner. The structure is simple, easy to disassemble and assemble, and has good connection stability. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 3 As shown, a commercial vehicle roof interior canopy connection assembly is used to connect the interior canopy to the roof of the commercial vehicle. It includes a connector that passes through the interior canopy. The connector includes a cylindrical fixing member 1. The upper end face of the fixing member has a cuboid protrusion 2. The lower end face of the fixing member has an upward-facing groove. The outer side wall of the fixing member has a fixing groove 3 that communicates with the groove. A limiting plate 4 is provided at the fixing groove. The upper end of the limiting plate is rotatably connected to the upper part of the fixing groove. An adjusting plate 5 is provided in the groove to abut against the limiting plate and cause it to open outward. The lower end of the adjusting plate is connected to a cover plate 7 through a connecting rod 6. A surrounding plate 8 is provided on the periphery of the cover plate. The surrounding plate and the lower part of the fixing member are threaded. The surrounding plate is screwed to the lower part of the fixing member. The fixing member also passes through a pressure plate 9. The upper end of the surrounding plate abuts against the pressure plate. The pressure plate is used to press the interior canopy tightly.

[0018] The adjusting plate includes a frustum-shaped adjusting part 10 that gradually increases in size from top to bottom. This allows the limiting plate to protrude from the fixing member and engage with the mating hole on the roof. Preferably, four sets of fixing grooves and limiting plates are provided, evenly distributed.

[0019] Furthermore, a pull wire is connected to the bottom of the limiting plate. This allows the limiting plate to move inward, thereby disengaging from the mating hole.

[0020] Furthermore, the protrusion is cubic in shape and is used to fit into the mating holes arranged on the roof. Specifically, the top wall of the mating hole is recessed with a square embedding groove, the protrusion is inserted into the limiting groove, and the lower end face of the mating hole is provided with a horizontally arranged ring plate. The fastener passes through the ring plate, and the limiting plate protrudes and abuts against the ring plate.

[0021] The working principle of this utility model is as follows: the fixing component passes through the interior roof and is inserted into the mating hole of the roof. At this time, the protrusion is inserted into the embedding groove. Then, the pressure plate is set, and then the adjusting plate extends into the groove. The surrounding plate is screwed to the fixing component. The surrounding plate abuts against the pressure plate, and the pressure plate abuts against the interior roof. At this time, the adjusting part of the adjusting component limits the limiting plate, so that it expands outward and is limited to the ring plate of the mating hole, thereby realizing the fixed connection of the interior roof. When disassembling, the surrounding plate rotates in the opposite direction to disengage from the fixing component. Pulling the pull line causes the limiting plate to retract inward, thereby disengaging from the mating hole.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
