DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second" etc. in the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged in appropriate circumstances, so that the embodiments of the present application described here. In the present application, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" etc. are based on the orientation or positional relationship shown in the accompanying drawings.

[0030] The embodiment of the present invention provides a car door guard plate structure, which adopts an assembly structure functional layout perpendicular to the door direction (Y direction), so that the installation is simple and the clamping reliability is higher. It solves the problems of the prior art that the car door guard plate is difficult to install, the Y-direction clamping position of the inner water retaining strip of the door guard plate is weak and easy to flip, the inner water retaining strip skirt and the assembly seam of the door guard plate are exposed, and the sensory quality is poor.

[0031] like Figure 1 As shown, a vehicle door guard plate structure includes a door guard plate assembly 1, as shown in Figure 2 As shown, a buckle 2 is provided on the top of the door guard plate assembly 1, and the door guard plate assembly 1 is fixed to the inner water retaining strip 3 and the vehicle door 4 by the buckle 2 along a direction perpendicular to the vehicle door 4 (Y direction).

[0032] The door guard plate assembly 1 of the embodiment of the present invention is assembled to the inner water retaining strip 3 and the vehicle door 4 in a direction perpendicular to the vehicle door 4 (Y direction) by means of the buckle 2, thereby reducing assembly difficulties.

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

[0034] Among them, the vertical cross-section of the door guard plate body 6 is curved, and a accommodating cavity is formed between the door guard plate body 6 and the vehicle door 4. The inner water retaining strip 3 and the buckle 2 are both located in the accommodating cavity. The door guard plate body 6 is sealed with the vehicle door 4 through the inner water retaining strip 3, and the inner water retaining strip 3 and the outer water retaining strip (not shown in the figure) work together to achieve the sealing of the glass of the vehicle door 4.

[0035] The top of the first connection part 7 is fixedly connected to the side of the door guard plate body 6 close to the vehicle door 4, and the bottom of the first connection part 7 is connected to one end of the second connection part 8. For example, the vertical cross-section of the first connection 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 fracture between the first connection part 7 and the door guard plate body 6 and improving the reliability and service life of the connection.

[0036] The other end of the second connecting portion 8 extends away from the vehicle door 4 and is connected to the top of the vertical portion 9, the bottom of the vertical portion 9 is connected to one end of the horizontal portion 10, the other end of the horizontal portion 10 extends toward the vehicle door 4 and is fixedly connected to the top of the card plate 11, the bottom of the card plate 11 is clamped with the side of the inner water retaining strip 3 away from the vehicle door 4, the inner water retaining strip 3 is also clamped with the support strip 12 on the vehicle door 4, the support strip 12 is located in the accommodating cavity and below the buckle 2, wherein the support strip 12 is a sheet metal part made of the same material as the vehicle door 4, for example, the horizontal portion 10 is also provided with a protrusion above the card plate 11.

[0037] For example, the angle between the second connection part 8 and the vertical part 9 is an obtuse angle. After being clamped, the second connection part 8 decomposes the horizontal force into horizontal force and vertical downward force, so that the clamping plate 11 and the inner water retaining strip 3 are clamped more tightly, thereby improving the clamping reliability.

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

[0039] like Figure 2 As shown, for example, the inner water retaining strip 3 includes a frame 13, and 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 a side close to the vehicle door 4, wherein the first sealing strip 20 is used to form a seal between the door guard plate body 6 and the vehicle door 4, the second sealing strip 21 and the third sealing strip 22 are sealed to the inner side surface of the glass of the vehicle door 4, and the outer water retaining strip is sealed to the outer side surface of the glass of the vehicle door 4.

[0040] A hook 14 is provided below the buckle 2 on the side of the frame 13 away from the vehicle door 4 , and the clamping plate 11 is clamped with the hook 14 to fix the door guard assembly 1 and the inner water strip.

[0041] For example, the bottom of the first sealing strip 20 is connected to the top of the side of the frame 13 close to the vehicle door 4, and the top of the first sealing strip 20 extends to below the top of the door guard plate body 6. The bottom of the second sealing strip 21 is connected to the middle of the side of the frame 13 close to the vehicle door 4, and the top of the second sealing strip 21 extends toward the top direction of the door guard plate body 6. 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 on one side close to the door 4 , and the top of the third sealing strip 22 extends toward the top of the door guard plate body 6 . There is a gap between the third sealing strip 22 and the second sealing strip 21 .

[0043] The skirts of the first sealing strip 20, the second sealing strip 21 and the third sealing strip 22 of the embodiment of the present invention are all located inside the door guard plate body 6, which solves the problem of exposed assembly seams between the skirt of the inner water retaining strip 3 and the door guard plate, resulting in poor visual quality.

[0044] like Figure 2 As shown in the figure, a schematic diagram of the states of the first sealing strip 20, the second sealing strip 21 and the third sealing strip 22 before and after deformation is shown. After deformation, the first sealing strip 20 is located inside the door guard plate 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, and 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 also located inside the door guard plate body 6, and the skirt of the inner water retaining strip 3 will not be exposed.

[0045] For example, the side of the first sealing strip 20, the second sealing strip 21 and the third sealing strip 22 close to the vehicle door 4 is coated with a fluff layer. By providing the fluff layer, the fluff layer is closely attached to the automobile glass during use. The fluff layer has a small friction coefficient and thus has good wear resistance. When the glass of the vehicle door 4 moves, the movement of the glass of the vehicle door 4 can prevent the soft sealing strip from being damaged, and can effectively protect the soft sealing strip and increase its service life. The fluff layer has dense wool yarns and can effectively play a role in waterproofing and blocking dust.

[0046] like Figure 2 As shown, for example, a slot 15 is provided on the frame 13, and the support bar 12 is inserted into the slot 15. A positioning tooth 16 is provided on the side wall of one side of the slot 15. The positioning tooth 16 is made of elastic material, and the top of the positioning tooth 16 is in contact with the support bar 12, so as to realize the connection and support between the inner water retaining bar 3 and the support bar 12.

[0047] For example, the hook 14 includes a horizontally arranged connecting plate 17, which is perpendicular to the card plate 11. The connecting plate 17 is provided with 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 surface of the card plate 11 away from the frame 13 abuts against the vertical side surface of the boss 18 close to the frame 13, thereby realizing the clamping connection between the hook 14 and the card plate 11.

[0048] For example, the side of the boss 18 away from the frame 13 is an arc surface 19, which plays a guiding role. When the door guard assembly 1 is installed, the bottom of the clamping 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
