[0006] Furthermore, the door panel assembly includes a door panel body, and the buckle includes a first connecting part, a second connecting part, a vertical part, a horizontal part, and a latching plate;

[0007] The door panel body forms a receiving cavity with the vehicle door, and the inner water baffle and the buckle are both located in the receiving cavity. The door panel body is sealed to the vehicle door by the inner water baffle. The top of the first connecting part is fixedly connected to the side of the door panel body near the vehicle door, and the bottom of the first connecting part is connected to one end of the second connecting part. The other end of the second connecting part extends away from the vehicle door and connects to the top of the vertical part. The bottom of the vertical part is connected to one end of the horizontal part. The other end of the horizontal part extends towards the vehicle door and is fixedly connected to the top of the clamping plate. The bottom of the clamping plate is engaged with the side of the inner water baffle away from the vehicle door. The inner water baffle is also engaged with the support strip on the vehicle door. The support strip is located in the receiving cavity and below the buckle.

[0008] Furthermore, the vertical cross-section of the first connecting part is arc-shaped.

[0009] Furthermore, the angle between the second connecting portion and the vertical portion is an obtuse angle.

[0010] Furthermore, the inner water baffle includes a frame, and the frame is provided with a first sealing strip, a second sealing strip and a third sealing strip at intervals from top to bottom on the side near the door;

[0011] The first sealing strip is used to form a seal between the door panel body and the door, and the second and third sealing strips seal the inner side of the door glass; a hook is provided below the buckle on the side of the frame away from the door, and the buckle plate engages with the hook.

[0012] Furthermore, the bottom of the first sealing strip is connected to the top of the frame near the door, the top of the first sealing strip extends to the bottom of the top of the door panel body, the bottom of the second sealing strip is connected to the middle of the frame near the door, the top of the second sealing strip extends toward the top of the door panel body, and there is a gap between the second sealing strip and the first sealing strip.

[0013] The bottom of the third sealing strip is connected to the bottom of the frame on the side near the door, and the top of the third sealing strip extends toward the top of the door panel body. There is a gap between the third sealing strip and the second sealing strip.

[0014] Furthermore, the sides of the first sealing strip, the second sealing strip, and the third sealing strip near the door are covered with a fleece layer.

[0015] Furthermore, the skeleton is provided with a slot, the support bar is inserted into the slot, and a positioning tooth is provided on one side wall of the slot.

[0016] Furthermore, the hook includes a horizontally arranged connecting plate, which is perpendicular to the locking plate.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," "longitudinal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0030] This invention provides an automotive door panel structure that adopts an assembly structure layout perpendicular to the door direction (Y-direction), making installation simpler and improving the reliability of the snap-fit. It solves the problems of difficult installation of automotive door panels in the prior art, weak strength of the Y-direction snap-fit ​​position of the inner water-retaining strip leading to easy flipping, and exposed seams between the inner water-retaining strip skirt and the door panel, resulting in poor visual quality.

[0031] like Figure 1 As shown, an automotive door panel structure includes a door panel assembly 1, such as... Figure 2 As shown, the top of the door panel assembly 1 is provided with a buckle 2, and the door panel assembly 1 is fixed to the inner water baffle 3 and the door 4 by the buckle 2 along the direction perpendicular to the door 4 (Y direction).

[0032] In this embodiment of the invention, the door guard panel assembly 1 is assembled onto the inner water baffle 3 and the door 4 via a snap fastener 2 in a direction perpendicular to the door 4 (Y direction), reducing assembly difficulties.

[0033] like Figure 2 As shown, for example, the door panel assembly 1 includes a door panel body 6, and the buckle 2 includes a first connecting part 7, a second connecting part 8, a vertical part 9, a horizontal part 10, and a latch plate 11.

[0034] The door panel body 6 has a curved vertical cross section, and a cavity is formed between the door panel body 6 and the door 4. The inner water deflector 3 and the buckle 2 are both located in the cavity. The door panel body 6 is sealed to the door 4 through the inner water deflector 3. The inner water deflector 3 and the outer water deflector (not shown in the figure) work together to seal the glass of the door 4.

[0035] The top of the first connecting part 7 is fixedly connected to the side of the door panel body 6 near the door 4, and the bottom of the first connecting part 7 is connected to one end of the second connecting part 8. For example, the vertical cross section of the first connecting part 7 is arc-shaped to reduce stress concentration. The arc-shaped design can disperse stress and reduce the possibility of stress concentration, thereby reducing the risk of breakage between the first connecting part 7 and the door panel body 6 and improving the reliability and service life of the connection.

[0036] The other end of the second connecting part 8 extends away from the door 4 and connects to the top of the vertical part 9. The bottom of the vertical part 9 is connected to one end of the horizontal part 10. The other end of the horizontal part 10 extends towards the door 4 and is fixedly connected to the top of the latch plate 11. The bottom of the latch plate 11 is engaged with the side of the inner water baffle 3 away from the door 4. The inner water baffle 3 is also engaged with the support strip 12 on the door 4. The support strip 12 is located in the receiving cavity and below the buckle 2. The support strip 12 is a sheet metal part made of the same material as the door 4. For example, the horizontal part 10 is also provided with a protrusion above the latch plate 11.

[0037] For example, the angle between the second connecting part 8 and the vertical part 9 is an obtuse angle. After the snap-fit, the second connecting part 8 decomposes the horizontal force into a horizontal and a vertically downward force, making the snap-fit ​​plate 11 and the inner water baffle 3 more tightly snap-fit ​​and improving the snap-fit ​​reliability.

[0038] The buckle 2 of this invention is connected to the door panel body 6 by setting a first connecting part 7, a second connecting part 8, a vertical part 9, and a horizontal part 10. The thickness or length of the first connecting part 7, the second connecting part 8, the vertical part 9, and the horizontal part 10 can be adjusted as needed to improve the strength of the buckle 2, thereby improving the snapping strength of the door panel assembly 1 in the direction perpendicular to the door 4 (Y direction) and improving the snapping reliability performance.

[0039] like Figure 2 As shown, for example, the inner water deflector 3 includes a frame 13. The frame 13 is provided with a first sealing strip 20, a second sealing strip 21 and a third sealing strip 22 spaced from top to bottom on the side near the door 4. The first sealing strip 20 is used to form a seal between the door panel body 6 and the door 4. The second sealing strip 21 and the third sealing strip 22 seal the inner side of the door 4 glass. The outer water deflector seals the outer side of the door 4 glass.

[0040] On the side of the frame 13 away from the door 4, a hook 14 is provided below the buckle 2. The clip plate 11 and the hook 14 are engaged to fix the door guard panel assembly 1 and the inner water baffle strip.

[0041] For example, the bottom of the first sealing strip 20 is connected to the top of the side of the frame 13 near the door 4, the top of the first sealing strip 20 extends to the bottom of the top of the door panel body 6, the bottom of the second sealing strip 21 is connected to the middle of the side of the frame 13 near the door 4, the top of the second sealing strip 21 extends towards the top of the door panel body 6, and there is a gap between the second sealing strip 21 and the first sealing strip 20.

[0042] The bottom of the third sealing strip 22 is connected to the bottom of the frame 13 near the door 4, and the top of the third sealing strip 22 extends toward the top of the door panel body 6. There is a gap between the third sealing strip 22 and the second sealing strip 21.

[0043] In this embodiment of the invention, the skirts of the first sealing strip 20, the second sealing strip 21, and the third sealing strip 22 are all located inside the door panel body 6, which solves the problem of exposed seams between the inner water-blocking strip 3 and the door panel, resulting in poor sensory quality.

[0044] like Figure 2 As shown in the figure, the first sealing strip 20, the second sealing strip 21, and the third sealing strip 22 are shown in the schematic diagram before and after deformation. After deformation, the first sealing strip 20 is located inside the door panel body 6. After deformation, the second sealing strip 21 is located in the gap between the first sealing strip 20 and the second sealing strip 21. After deformation, the third sealing strip 22 is located in the gap between the second sealing strip 21 and the third sealing strip 22. It can be seen that after deformation, the sealing strips are all located inside the door panel body 6, and the inner water-blocking strip 3 skirt will not be exposed.

[0045] For example, the first sealing strip 20, the second sealing strip 21, and the third sealing strip 22 are covered with a fleece layer on the sides near the car door 4. This fleece layer adheres tightly to the car glass during use. The fleece layer has a low coefficient of friction, thus exhibiting excellent wear resistance. When the car door 4 glass moves, it prevents damage to the soft sealing strip caused by the movement of the glass, effectively protecting the soft sealing strip and extending its service life. Furthermore, the dense fibers of the fleece layer provide excellent waterproofing and dust-proofing properties.

[0046] like Figure 2 As shown, for example, the frame 13 is provided with a slot 15, the support strip 12 is inserted into the slot 15, and a positioning tooth 16 is provided on one side wall of the slot 15. The positioning tooth 16 is made of elastic material, and the top of the positioning tooth 16 contacts the support strip 12 to realize the engagement and support of the inner water baffle 3 and the support strip 12.

[0047] For example, the hook 14 includes a horizontally arranged connecting plate 17, which is perpendicular to the locking plate 11. The connecting plate 17 has a boss 18 on the side away from the frame 13. A groove is formed between the boss 18, the connecting plate 17 and the frame 13. The vertical side of the locking plate 11 away from the frame 13 abuts against the vertical side of the boss 18 near the frame 13, thereby realizing the locking of the hook 14 and the locking plate 11.

[0048] For example, the side of the boss 18 away from the frame 13 is an arc surface 19. The arc surface 19 acts as a guide. When the door panel assembly 1 is installed, the bottom of the retaining plate 11 slides along the arc surface 19, is guided into the groove, and abuts against the boss 18. The height of the boss 18 can be set as needed, such as... Figure 2 As shown, for example, the distance B between the highest point of the boss 18 and the connecting plate 17 is 1.45 mm.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
