Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, and in particular relates to a double-layer plate side skirt structure and a vehicle. Background Art

[0002] With the development of technology and people's increasing requirements for quality, the current automotive industry not only has higher and higher requirements for functionality but also has stricter requirements for appearance quality. Conventional side skirt guards mostly use a single-layer plate structure. This structure can well ensure the installation accuracy but is very prone to poor appearance shrinkage. The traditional approach is to use leather grain technology to slightly cover up this defect.

[0003] However, in order to achieve a better appearance, the styling is generally upgraded to spray painting, especially high-gloss spray painting. This process can improve the visual appearance, but it further increases the requirements for the single piece, because spray painting has an amplifying effect on the appearance reduction, so the appearance of the side skirt is very challenging. Another challenge for the single-layer structure of products above 2000mm such as side skirts is: the degree of conformity between product size and data. In theory, it is very difficult to control the size deviation of a part within one thousandth, but even if it is controlled to one thousandth, it cannot meet the quality requirements of people at this stage. One thousandth of 2000mm is 2mm, which will cause a gap in the matching position with the car body, and even interference when the door is opened and closed.

[0004] It is hoped to provide an improved double-layer plate side skirt structure, especially how to solve the appearance problems caused by traditional side skirts while ensuring assembly accuracy, so as to qualitatively improve the quality of the side skirts. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a double-layer plate side skirt structure, the purpose of which is to improve the quality of the side skirt while ensuring assembly accuracy.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a double-layer side skirt structure, including an outer panel and an inner panel, the outer panel is connected to the inner panel through a mounting mechanism, the inner panel is configured to be connected to the vehicle body, and the outer panel is located on the outside of the inner panel.

[0007] The mounting mechanism comprises a boss arranged on the inner plate, and the boss is connected to the outer plate by welding.

[0008] The boss is arranged at the upper end of the inner plate, and the boss is connected to the upper end of the outer plate.

[0010] The outer plate is provided with an anti-dropping reverse stop for limiting the single-sided buckle.

[0011] The anti-slip backstop is located above the single-side buckle.

[0012] The single-side buckle is arranged at the lower edge of the outer plate, and the clamping seat is provided with a receiving groove for the lower end of the outer plate to be inserted.

[0013] The mounting mechanism comprises a positioning plug-in sheet arranged on the outer plate, and a positioning hole for inserting the positioning plug-in sheet is arranged on the inner plate.

[0039] Example

[0040] First, as Figures 1 to 6 As shown, an embodiment of the present invention provides a double-layer side skirt structure, including an outer panel 3 and an inner panel 4, the outer panel 3 is connected to the inner panel 4 through a mounting mechanism, the inner panel 4 is configured to be connected to the body of a vehicle, the outer panel 3 is located on the outside of the inner panel 4, and the inner panel 4 is located between the body and the outer panel 3.

[0041] Specifically, the embodiment of the present invention provides a double-layer side skirt structure, which can solve the appearance problems caused by traditional side skirts while ensuring the assembly accuracy, so that the quality of the side skirts is qualitatively improved. The general structure of the double-layer side skirt structure is to disassemble the side skirt into an inner panel 4 and an outer panel 3, and the inner panel 4 is connected to the outer panel by designing a square positioning hole in the outer panel 3 / a counter-block of the single-sided buckle 5 of the outer panel 3 / a square outer panel 3 buckle seat 6 / a square outer panel 3 welding boss 8. The through-style decorative panel buckle seat 2 / positioning column is designed to be connected to the sheet metal. The outer panel 3 is designed with a folded edge positioning insert 9 / a folded edge single-sided buckle 5 to be connected to the inner panel 4. It is possible to avoid the appearance problem of poor shrinkage due to the back mounting structure (especially spray-painted parts) while ensuring good positioning accuracy of the inner and outer panels 3, the side skirt assembly and the sheet metal accuracy.

[0042] like Figure 7 The figure shows the existing side skirt guard plate structure and the locations where problems may occur. The existing side skirt guard plate adopts an integrated structure. Although the structure has been optimized to avoid poor appearance, such as Figure 7The decorative panel buckle seats 2 are arranged at the rounded corners of the outer panel 3 and the buckle seats 6 are thinned, but this structure still requires the mold to be core-pulled (the blank area where A / B is located in the figure). Due to the core-pulling movement and the characteristics of the plastic part molding process, the poor appearance cannot be solved.

[0043] Existing side skirt guard plate products are generally around 2000mm. Even if the size is controlled to one thousandth, the product will still have unacceptable appearance problems such as visible wave distortion of the product (especially intermittent holes will appear at the joint between the upper edge of the side skirt and the sheet metal), and even affect the function such as interference with door opening.

[0044] like Figures 1 to 6 As shown, the mounting mechanism includes a boss 8 disposed on the inner plate 4, and the boss 8 is welded to the outer plate 3. The boss 8 is disposed at the upper end of the inner plate 4, the boss 8 is connected to the upper end of the outer plate 3, and the boss 8 is located between the outer plate 3 and the inner plate 4.

[0045] Preferably, the boss 8 and the inner plate 4 are integrally formed, which is convenient for processing.

[0046] like Figures 1 to 6 As shown, the installation mechanism includes a unilateral buckle 5 arranged on the outer panel 3 and a buckle seat 6 arranged on the inner panel 4, and the unilateral buckle 5 and the buckle seat 6 are connected by a snap connection. The unilateral buckle 5 is arranged at the lower edge of the outer panel 3, and the unilateral buckle 5 has a certain elasticity to ensure that the necessary clamping force and installation convenience can be provided during the snap connection process. A slot for inserting the unilateral buckle 5 is provided on the buckle seat 6. Multiple unilateral buckles 5 are provided, and all unilateral buckles 5 are arranged in sequence along the length direction of the outer panel 3 and are equidistantly distributed. The number of buckle seats 6 is the same as the number of unilateral buckles 5, and each unilateral buckle 5 is matched with a buckle seat 6. This design ensures the accuracy and reliability of the connection.

[0047] like Figures 1 to 6As shown, as preferably, in an embodiment of the present invention, an anti-slipping stopper 7 for limiting the unilateral buckle 5 is provided on the outer plate 3. The anti-slipping stopper 7 is located above the unilateral buckle 5. The anti-slipping stopper 7 is tilted, the upper end of the anti-slipping stopper 7 is fixedly connected to the outer plate 3, and the lower end of the anti-slipping stopper 7 is used to contact the top surface of the unilateral buckle 5, which can limit the unilateral buckle 5, prevent the unilateral buckle 5 from separating from the buckle seat 6, and lock the outer plate 3. This tilted design of the anti-slipping stopper 7 not only helps the smooth insertion of the unilateral buckle 5, but also provides additional locking force after the buckle is in place. When the unilateral buckle 5 is fully inserted into the slot of the buckle seat 6, the lower end of the anti-slipping stopper 7 will contact the top surface of the unilateral buckle 5. This contact not only limits the movement of the unilateral buckle 5 in the vertical direction, but also prevents the accidental separation between the unilateral buckle 5 and the buckle seat 6 by friction or physical blocking. The anti-dropping backstop 7 can effectively lock the outer panel 3 to prevent it from loosening or falling off when subjected to external force, which is very important for improving the stability and reliability of the entire side skirt structure.

[0048] Preferably, the unilateral buckle 5 and the anti-slipping stop 7 are integrally formed with the outer plate 3, and the buckle seat 6 is integrally formed with the inner plate 4, which is convenient for processing. The number of unilateral buckles 5 and anti-slipping stop 7 is the same, and each anti-slipping stop 7 is used to limit a unilateral buckle 5.

[0049] like Figures 1 to 6 As shown, the mounting mechanism includes a positioning plug 9 provided on the outer panel 3, and a positioning hole for inserting the positioning plug 9 is provided on the inner panel 4. The positioning plug 9 extends toward the outer side of the outer panel 3, and the positioning hole is a through hole provided on the inner panel 4 along the thickness direction. The matching design of the positioning plug 9 and the positioning hole ensures that the inner panel 4 and the outer panel 3 can be accurately aligned during installation, avoiding the problem of misalignment or offset, and effectively ensuring the installation accuracy of the inner panel 4 and the outer panel 3. Once the positioning plug 9 is inserted into the positioning hole, the tight fit between them will provide additional stability and help maintain the integrity of the entire structure. Since errors and adjustment time are reduced during the installation process, it helps to reduce production costs.

[0050] Preferably, the positioning insert 9 is arranged at the upper bending portion 10 of the outer plate 3, and the positioning insert 9 and the outer plate 3 are integrally formed, which is convenient for processing. A plurality of positioning inserts 9 are provided, and all positioning inserts 9 are arranged in sequence along the length direction of the outer plate 3 and are equidistantly distributed. The number of positioning inserts 9 is the same as the number of positioning holes, and each positioning insert 9 is matched with a positioning hole.

The connection between the first outer wall 11 and the second outer wall 12 forms an upper bending part 10, the connection between the third outer wall 13 and the fourth outer wall 14 forms a lower bending part, the single-sided buckle 5 is fixedly connected to the lower edge of the fourth outer wall 14 (i.e., the lower edge of the outer panel 3), and the lower edge of the fourth outer wall 14 is inserted into the receiving groove. On the outer panel 3, the positioning insert 9 and the single-sided buckle 5 are both designed at the folding edge of the side skirt, so there will be no shrinkage defects in the appearance, maintaining the beauty and neatness of the side skirt.

[0053] like Figures 4 to 6 As shown, the inner plate 4 includes a first inner wall 15, a second inner wall 16, a third inner wall 17 and a fourth inner wall 18 connected in sequence, the boss 8 is fixedly connected to the first inner wall 15, the first inner wall 15 is located on the inner side of the first outer wall 11, the lower end of the first inner wall 15 is fixedly connected to one end of the second inner wall 16, the first inner wall 15 and the second inner wall 16 have an angle and the angle is an obtuse angle, the second inner wall 16 is located below the second outer wall 12, and the second inner wall 16 is The other end is fixedly connected to the upper end of the third inner side wall 17, there is an angle between the second inner side wall 16 and the third inner side wall 17, and the angle is an acute angle, the third inner side wall 17 is located on the inner side of the third outer side wall 13, the lower end of the third inner side wall 17 is fixedly connected to the upper end of the snap seat 6, the lower end of the snap seat 6 is fixedly connected to the upper end of the fourth inner side wall 18, the fourth inner side wall 18 is located below the outer panel 3, the first inner side wall 15, the second inner side wall 16 and the snap seat 6 are located on the same side of the third inner side wall 17.
