[0002] With the growing popularity of comfortable, clean, and lightweight interiors and finishes, comfortable, clean, and aesthetically pleasing interiors have become an important trend in the design of fuel-powered three-wheeled cargo motorcycles. However, traditional interior systems in the industry often use bolts with exposed screws, and the upper stop and water-cutting strip are not directly connected, resulting in an unsightly appearance, easy detachment of the water-cutting strip, and easy deformation during assembly.

[0003] Currently, utility model patent CN219133822U discloses a door panel assembly and a vehicle having the same, comprising a door panel body and a water-cutting strip. The door panel body includes a flanged portion that folds towards the window glass. The water-cutting strip is disposed between the door panel body and the window glass and contacts the window glass. The water-cutting strip is snap-fitted into the door panel body. The flanged portion covers the upper part of the water-cutting strip, and at least a portion of the water-cutting strip overlaps with the flanged portion. The water-cutting strip snaps into the door panel body, and the entire assembly is supplied after the water-cutting strip is assembled on it. This reduces the number of assembly steps on the OEM assembly line, reduces assembly tolerances, and improves assembly efficiency. Furthermore, the flanged portion folding towards the window glass on the door panel body can cover the water-cutting strip, improving the overall aesthetics of the door panel assembly and preventing direct sunlight from hitting the water-cutting strip, thereby reducing its aging rate and extending its service life.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN219133822U improves the overall aesthetics of the vehicle by setting the above-mentioned door panel assembly, and can reduce the installation process on the OEM assembly line and improve vehicle assembly efficiency. However, this patent requires adding a skeleton inside a whole water-cutting strip, which increases production costs. At the same time, the water-cutting strip cannot be used to assemble the water-cutting strip, the inner panel of the door sheet metal and the upper edge of the door guard plate, and cannot solve the problem of too many screws. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a fixing structure for the water-cutting strip of a semi-enclosed cab door. This structure can solve the problems of not being able to fix the water-cutting strip after fixing the interior door panel and the water-cutting strip being easily deformed.

[0006] To achieve the above objectives, this utility model is applicable to the fixing structure of the water-cutting strip of a semi-enclosed cab door, including an inner water-cutting strip. The top of the inner sheet metal panel and the door guard panel are attached together. The top of the buckle plate is connected to the top of the rear retaining piece through a bending part to form a rear retaining groove. After the buckle plate passes through the buckle mounting hole, it fixes the inner sheet metal panel and the door guard panel through the rear retaining groove. The lower part of the rear retaining piece is connected to the front retaining piece through a bending part to form a water-cutting strip mounting groove. The inner water-cutting strip fixing part of the inner water-cutting strip is inserted into the water-cutting strip mounting groove, and the rear part of the inner water-cutting strip overlaps the upper edge of the door guard panel.

[0007] In addition, the fixing structure for the water-cutting strip of a semi-enclosed cab door proposed in the above embodiments of this utility model may also have the following additional technical features: As a further improvement of this utility model, the inner water-cutting strip protrudes outward from the side facing the inner panel of the car door sheet metal.

[0008] As a further improvement of this utility model, the upper part of the front retaining plate is bent forward, and the lower part of the retaining plate is bent backward.

[0009] As a further improvement of this utility model, the buckle is made of engineering plastic or spring plate.

[0010] As a further improvement of this utility model, the surfaces of the front and rear retaining pieces are hollowed out.

[0011] By means of the above solution, this utility model has at least the following advantages: Compared with conventional screw fixing, by adding buckles, the upper edge of the inner panel of the car door sheet metal and the door guard plate can be concealed and fixed together. At the same time, by using the buckle to fix the water cutter strip mounting groove, the problem of not being able to fix the car door water cutter strip after fixing the interior door panel and the water cutter strip being easy to deform can be solved. This can effectively improve the aesthetics of the car door and prevent the water cutter strip from loosening. Attached Figure Description

[0013] The following description, in conjunction with the accompanying drawings, describes the fixing structure of the water-cutting strip for a semi-enclosed cab door according to this utility model.

[0014] In Embodiment 1 of this application, as Figures 1 to 4 As shown, this invention (hereinafter referred to as "the invention") is applicable to the fixing structure of the water-cutting strip for a semi-enclosed cab door. It includes an inner water-cutting strip 1, a door sheet metal inner panel 3, and a door guard panel 4. The tops of the door sheet metal inner panel 3 and the door guard panel 4 are fitted together. The top of the clip 23 of the clip 2 is connected to the top of the rear retaining piece 22 through a bend to form a rear retaining groove. The clip 23 passes through the clip mounting hole 41 and then fixes the door sheet metal inner panel 3 and the door guard panel 4 through the rear retaining groove. The lower part of the rear retaining piece 22 is connected to the front retaining piece 21 through a bend to form a water-cutting strip mounting groove. The inner water-cutting strip fixing part 11 of the inner water-cutting strip 1 is inserted into the water-cutting strip mounting groove, and the rear part of the inner water-cutting strip 1 overlaps the upper edge of the door guard panel 4. The inner water-cutting strip 1 protrudes outwards from the side facing the door sheet metal inner panel 3.

[0015] The utility model patent CN219133822U describes a door panel assembly and a vehicle having the same assembly (hereinafter referred to as "the patent"). By setting up the aforementioned door panel assembly, the overall aesthetics of the vehicle are improved, and the assembly process on the OEM assembly line can be reduced, thus improving vehicle assembly efficiency. However, the patent requires adding a skeleton within a single water-cutting strip, increasing production costs. Furthermore, the water-cutting strip cannot be used to assemble the water-cutting strip, the inner panel of the door sheet metal, and the upper edge of the door guard plate, and it does not solve the problem of excessive screw connections. In contrast, the present invention adds a buckle 2, which allows the upper edges of the inner panel of the door sheet metal 3 and the door guard plate 4 to be concealed and fixed together. At the same time, the water-cutting strip 1 is fixed by the water-cutting strip mounting groove of the buckle 2, which solves the problems of not being able to fix the water-cutting strip after fixing the interior door panel and the water-cutting strip being prone to deformation. This effectively improves the aesthetics of the door and prevents the water-cutting strip from loosening.

[0016] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 4 As shown, to make assembly easier for workers, the upper part of the front clamp 21 is bent forward, and the lower part of the clamping plate 23 is bent backward.

[0017] To further optimize the working efficiency of this application, the buckle 2 is made of engineering plastic or spring plate. The surfaces of the front retaining piece 21 and the rear retaining piece 22 are hollowed out.

[0018] This design is suitable for installing the water-cutting strip on the semi-enclosed cab door. The pre-designed clip 2's clip plate 23 is embedded into the pre-drilled clip mounting hole 41 on the door panel 4 and the sheet metal mating area. After locking, the inner water-cutting strip fixing part 11 of the inner water-cutting strip 1 is inserted into the water-cutting strip mounting groove, covering the inner sheet metal panel 3 and the door panel 4, ensuring it is properly engaged and securely locked. The interface effectively connects to the upper edge of the interior door panel, resulting in a neat, aesthetically pleasing, and integrated appearance. When the door panel needs repair, simply remove the adhesive strip, disassemble clip 2, and then disassemble and reassemble the door panel normally. This design solves the common problems of misalignment, unsightly gaps, and ineffective installation of water-cutting strips and door panels. Compared to traditional structures, the removal of reinforcing ribs at the door panel stop and the elimination of the internal steel strip in the inner water-cutting strip reduce costs.

[0019] In summary, the fixing structure of the water-cutting strip for the semi-enclosed cab door of this utility model embodiment, by adding buckle 2, allows the upper edge of the inner sheet metal panel 3 and the door guard panel 4 to be concealed together. At the same time, by fixing the inner water-cutting strip 1 with the water-cutting strip mounting groove of buckle 2, the problems of not being able to fix the door water-cutting strip after fixing the interior door panel and the water-cutting strip being easily deformed can be solved. This can effectively improve the aesthetics of the door and prevent the water-cutting strip from loosening.
