Description

Technical Field

[0001] The utility model relates to the technical field of vehicle interior decoration assembly, in particular to a D-pillar upper guard plate connection structure and a vehicle. Background Art

[0002] Currently, the D-pillar upper guard plate of a sedan, when assembled onto the body-in-white (BW), suffers from poor boundary stability, prone to deformation, and uneven clearance with the black strip of the windshield. This is because the connecting structure between the D-pillar upper guard plate and the BW requires high stability and is large in size. However, due to the narrow space between the D-pillar upper guard plate and the BW, the connecting structure cannot be located close to the D-pillar upper guard plate's boundary. Consequently, the existing connecting structure has limited control over the D-pillar upper guard plate's boundary, making it prone to deformation and reducing the overall vehicle's quality.

[0003] Existing D-pillar upper guard plate boundary connection structures, such as the D-pillar upper guard plate boundary fixing structure involved in CN212921703U, fix the boundary by adding metal clips between the D-pillar upper guard plate and the body-in-white sheet metal. However, the metal clips are easy to fall off, and the installation structure is relatively complex and the assembly is cumbersome. High requirements are placed on the installation accuracy. Once the installation is not in place, the control force on the boundary cannot be guaranteed. Utility Model Content

[0042] Example 1

[0043] See also Figure 1-4 As shown, an embodiment of the present application provides a D-pillar upper guard plate connection structure, comprising:

[0044] A first clamping structure 1, the upper end of which is arranged in the middle of the D-pillar upper guard plate 5 and the lower end of which is clamped to the body-in-white;

[0045] A second clamping structure 2, the upper end of which is arranged at the boundary of the D-pillar upper guard plate 5, and the lower end of which is clamped to the flange of the body-in-white;

[0046] A reinforcing rib is connected to the side of the second clamping structure 2 away from the first clamping structure 1 .

[0047] The D-pillar upper guard plate connection structure incorporates a second clipping structure 2 in addition to the first clipping structure 1. The first clipping structure 1 ensures the connection strength between the D-pillar upper guard plate 5 and the entire body-in-white (BIW). The second clipping structure 2, positioned at the edge of the D-pillar upper guard plate 5, ensures the stability of the D-pillar upper guard plate's boundary. Reinforcing ribs are attached to the side of the second clipping structure facing away from the first clipping structure 1, giving it greater strength and further ensuring stability when clipped to the BIW flange. Its simple structure reduces assembly difficulty and overall cost.

[0048] See also Figure 1 、 2 As shown in FIG. 4 , the second clamping structure 2 includes:

[0049] A first connecting plate 21, the upper end of which is mounted on the lower end surface boundary of the D-pillar upper guard plate 5;

[0050] The second connecting plate 22 has its upper end mounted on the lower edge of the D-pillar upper guard plate 5, its side end connected to the side end of the first connecting plate 21, and its lower end engaged with the body-in-white flange;

[0051] The upper end of the reinforcing rib is set at the lower end surface boundary of the D-pillar upper guard plate 5, the left end of the reinforcing rib is connected to the side surface of the upper end of the second connecting plate 22 close to the boundary of the D-pillar upper guard plate 5, and the right end extends outside the boundary of the D-pillar upper guard plate 5.

[0052] The first connecting plate 21 and the second connecting plate 22 are connected to each other and are both connected to the boundary of the lower end surface of the D-pillar upper guard plate 5, which enhances the stability of the second connecting plate 22 when subjected to force. The reinforcing ribs are connected to the side of the second connecting plate 22 close to the boundary of the D-pillar upper guard plate 5 and extend outside the boundary of the D-pillar upper guard plate 5, making it difficult for the second connecting mechanism 2 to bend, ensuring the stability of the lower end of the second connecting plate 22 when it is clamped with the white body flange. The second clamping structure 2 can achieve higher strength with a smaller size.

[0053] See also Figure 2 As shown, it also includes a first reinforcing plate 3 , the left end of the first reinforcing plate 3 is connected to the first clamping structure 1 , and the right end of the first reinforcing plate 3 is connected to the side of the second connecting plate 22 away from the first connecting plate 21 .

[0054] The first reinforcing plate 3 increases the strength of the second connecting plate 22 and the first clamping structure 1 , thereby preventing the second connecting plate 22 from bending toward the direction of the first clamping structure 1 due to excessive force.

[0055] See also Figure 2 As shown, it also includes a second reinforcing plate 4, the upper end of which is installed at the lower end surface boundary of the D-pillar upper guard plate 5, and the side end of the second reinforcing plate 4 is connected to the side of the first connecting plate 21 away from the second connecting plate 22.

[0056] The second reinforcing plate 4 increases the strength of the first connecting plate 21 , preventing the first connecting plate 21 from bending in a direction away from the second connecting plate 22 due to excessive force.

[0057] See also Figure 1 、 2 As shown in FIG4 , a felt layer 221 is provided on the lower end of the second connecting plate 22 , and the lower end of the second connecting plate 22 is connected to the flange of the body in white through the felt layer 221 .

[0058] Since the first connecting plate 21 is made of plastic and the body-in-white flange is made of sheet metal, direct connection between the two can easily cause friction and produce abnormal noise during vehicle operation. The felt layer 221 is provided to prevent the occurrence of abnormal noise. When the felt layer 221 is 1 mm thick, it has a better performance.

[0059] See also Figure 1 、 2 As shown in FIG. 3 , the first clamping structure 1 includes:

[0060] Support base 11, the upper end of the support base 11 is installed in the middle of the lower end surface of the D-pillar upper guard plate, and the lower end of the support base 11 is provided with a card interface 111-1;

[0061] The clamping head 12 has an upper end installed in the clamping interface 111 - 1 and a lower end clamped with the body-in-white.

[0062] The upper end of the clamping head 12 is installed in the support base 11 through the clamping interface 111 - 1 , and the clamping head 12 is then clamped and fixed to the body-in-white, with high connection stability.

[0063] See also Figure 1 、 2 As shown in FIG. 3 , the support base 11 includes:

[0064] A base plate 111, on which a card interface 111-1 is provided;

[0065] The side panel 112 has an upper end mounted on the middle portion of the lower end surface of the D-pillar upper guard plate 5 , and a lower end edge of the side panel 112 is matched and connected with an edge of the bottom plate 111 . The inner side of the side panel 112 is provided with transverse support ribs and vertical support ribs.

[0066] The inner side of the side wall 112 is provided with transverse support ribs and vertical support ribs, so that the support base 11 has high stability and structural strength, and the space enclosed by the side wall 112 can accommodate the upper end of the card head at the card interface 111-1.

[0067] See also Figure 1 、 2 As shown in FIG. 3 , the cross section of the side panel 112 is U-shaped, and a notch is provided on the side of the card interface 111 - 1 facing the U-shaped opening of the side panel 112 , and the card head 12 is installed in the card interface 111 - 1 through the notch.

[0068] The cross section of the side panel 112 is U-shaped and the card interface 111 - 1 is provided with a notch, so that the card head 12 can be installed on the support seat 11 through the notch, which is convenient for assembly.

[0069] See also Figure 1 、 2 As shown, a conical connecting piece is further provided at the lower end of the bottom plate 111 .

[0070] The conical connector can play an auxiliary positioning role. The conical connector is relatively long. Before the clamping head 12 is clamped into the white body, a part of the conical connector is first inserted into the preset positioning hole in the white body, and then the clamping head 12 is clamped into the white body, which ensures accurate positioning and makes the assembly of the clamping head 12 more convenient.

[0071] Furthermore, a bending portion is provided at the lower end of the second connecting plate 22, and the angle between the two sides of the bending portion is 135°. The part below the bending portion is vertically inserted into the white body flange by 3.4 mm. The bottom of the lower end of the second connecting plate 22 (excluding the felt layer) is 3.5 mm away from the rear windshield. The thickness of the plate of the second connecting plate 22 vertically inserted into the white body flange is 3.7 mm.

[0072] Example 2

[0073] An embodiment of the present application provides an automobile, comprising the above-mentioned D-pillar upper guard plate connection structure.

[0074] The working principle of this utility model is:

[0075] During installation, the D-pillar upper guard plate is first connected to the white body through the first clamping structure 1, and then the boundary of the D-pillar upper guard plate is connected to the white body flange through the second clamping structure 2. Since the second clamping structure 2 includes a first connecting plate 21 and a second connecting plate 22, the upper end of the second connecting plate 22 is connected with a reinforcing rib, and the first connecting plate 21 and the second connecting plate 22 are respectively connected with a reinforcing plate. The second clamping structure 2 occupies a small volume and has a high structural strength. It can be installed in the narrow space formed between the boundary of the D-pillar upper guard plate and the white body flange, and the design of a felt layer sheathed on the outside of the lower end of the second connecting plate 22 can effectively solve the abnormal noise problem.
