Abstract
Description
Technical Field
[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a double-layer side skirt structure and a vehicle. Background Technology
[0002] With the development of technology and people's increasing demands for quality, the automotive industry today not only has higher and higher requirements for functionality, but also for appearance quality. Conventional side skirts mostly use a single-layer plate structure. This structure can ensure installation accuracy well, but it is very easy to have poor appearance shrinkage. The traditional approach is to use a leather texture process to slightly cover up this defect.
[0003] However, nowadays, to achieve a better aesthetic appearance, the styling is generally upgraded to spray painting, especially high-gloss spray painting. While this process improves the visual appearance, it further increases the requirements for individual parts because spray painting has a magnifying effect on the appearance of the print. Therefore, the appearance of the side skirt is very challenging. For products like side skirts with a diameter of over 2000mm and a single-layer panel structure, another challenge is the degree of conformity between the product dimensions and the data. Theoretically, controlling the dimensional deviation of a single part to one-thousandth is considered acceptable and very difficult. However, even controlling it to one-thousandth cannot meet the current quality requirements. One-thousandth of 2000mm is 2mm, which will create gaps at the matching position with the car body and may even cause interference when the door is opened and closed.
[0004] The aim is to provide an improved double-layer side skirt structure, particularly regarding how to solve the appearance problems caused by traditional side skirts while ensuring assembly accuracy, thereby significantly improving the quality of the side skirts. Summary of the Invention

[0010] The outer plate is provided with an anti-detachment and anti-reverse stop for limiting the single-sided buckle.
[0011] The anti-detachment buckle is located above the single-sided buckle.
[0012] The single-sided buckle is located at the lower edge of the outer panel, and the snap-fit seat is provided with a receiving groove for inserting the lower end of the outer panel.
[0013] The mounting mechanism includes a positioning insert on the outer plate and a positioning hole on the inner plate for inserting the positioning insert.

[0036] The installation mechanism includes a positioning insert 9 disposed on the outer plate 3, and a positioning hole is provided on the inner plate 4 for inserting the positioning insert 9.
[0037] The positioning insert 9 is disposed on the upper bending portion 10 of the outer plate 3.
[0038] The present invention also provides a vehicle including the aforementioned double-layer panel side skirt structure.
[0039] Example
[0040] Firstly, such as Figures 1 to 6 As shown, an embodiment of the present invention provides a double-layer panel 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 an installation mechanism. The inner panel 4 is configured to be connected to the vehicle body. The outer panel 3 is located outside the inner panel 4, and the inner panel 4 is located between the vehicle body and the outer panel 3.
[0041] Specifically, this invention provides a double-layer panel side skirt structure that solves the appearance problems caused by traditional side skirts while ensuring assembly accuracy, thus significantly improving the quality of the side skirt. The general structure of this double-layer panel side skirt is that the side skirt is divided into an inner panel 4 and an outer panel 3. The inner panel 4 is connected to the outer panel 3 via a square positioning hole, a single-sided buckle 5, a square buckle seat 6, and a welding boss 8. A through-type decorative panel buckle 2 and a positioning post are designed to connect with the sheet metal. The outer panel 3 is designed with a folded edge positioning insert 9 and a folded edge single-sided buckle 5 to connect with the inner panel 4. This structure can avoid appearance defects caused by shrinkage due to the back-mounted structure (especially for painted parts) while ensuring good positioning accuracy of the inner and outer panels 3 and the accuracy of the side skirt assembly and sheet metal.
[0042] like Figure 7 The diagram illustrates the existing side skirt panel structure and potential problem areas. The existing side skirt panels use a one-piece structure. Although the structural layout has been optimized to avoid aesthetic issues, such as… Figure 7The two decorative panel fasteners are located at the rounded corners of the outer panel 3, and the fastener 6 has been thinned. However, this structure still requires core pulling in the mold (the blank area where A / B is in the figure). Due to the characteristics of plastic part molding process, the poor appearance caused by the core pulling movement cannot be solved.
[0043] Existing side skirt panels are generally around 2000mm. Even with a size control of one-thousandth, unacceptable appearance problems still exist, such as visible wavy distortion (especially intermittent holes at the joint between the upper edge of the side skirt and the sheet metal), and even affect functionality, such as door opening interference.
[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, and the boss 8 is connected to the upper end of the outer plate 3. 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 single-sided latch 5 on the outer panel 3 and a latch seat 6 on the inner panel 4. The single-sided latch 5 and the latch seat 6 are connected by a snap-fit mechanism. The single-sided latch 5 is located at the lower edge of the outer panel 3 and has a certain degree of elasticity to ensure that it can provide the necessary clamping force and ease of installation during the snap-fit process. The latch seat 6 has a slot for inserting the single-sided latch 5. Multiple single-sided latches 5 are provided, and all single-sided latches 5 are arranged sequentially and equidistantly along the length of the outer panel 3. The number of latch seats 6 is the same as the number of single-sided latches 5, and each single-sided latch 5 mates with one latch seat 6. This design ensures the accuracy and reliability of the connection.
[0047] like Figures 1 to 6As shown, in a preferred embodiment of the invention, the outer plate 3 is provided with an anti-detachment stop 7 for limiting the single-sided buckle 5. The anti-detachment stop 7 is located above the single-sided buckle 5. The anti-detachment stop 7 is inclined, with its upper end fixedly connected to the outer plate 3 and its lower end contacting the top surface of the single-sided buckle 5, thus limiting the single-sided buckle 5, preventing it from separating from the buckle seat 6, and locking the outer plate 3 securely. This inclined design of the anti-detachment stop 7 not only facilitates the smooth insertion of the single-sided buckle 5 but also provides additional locking force after the buckle is in place. When the single-sided buckle 5 is fully inserted into the slot of the buckle seat 6, the lower end of the anti-detachment stop 7 will contact the top surface of the single-sided buckle 5. This contact not only restricts the vertical movement of the single-sided buckle 5 but also prevents accidental separation between the single-sided buckle 5 and the buckle seat 6 through friction or physical obstruction. The anti-detachment retainer 7 effectively locks the outer panel 3, preventing it from loosening or falling off when subjected to external forces. This is crucial for improving the stability and reliability of the entire side skirt structure.
[0048] Preferably, the single-sided buckle 5 and the anti-detachment 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 single-sided buckles 5 and anti-detachment stops 7 is the same, and each anti-detachment stop 7 is used to limit the position of one single-sided buckle 5.
[0049] like Figures 1 to 6 As shown, the mounting mechanism includes a positioning insert 9 on the outer panel 3 and a positioning hole on the inner panel 4 for inserting the positioning insert 9. The positioning insert 9 extends outward from the outer panel 3, and the positioning hole is a through hole extending along the thickness direction of the inner panel 4. The mating design of the positioning insert 9 and the positioning hole ensures that the inner panel 4 and the outer panel 3 are precisely aligned during installation, avoiding misalignment or offset, and effectively guaranteeing the installation accuracy of the inner panel 4 and the outer panel 3. Once the positioning insert 9 is inserted into the positioning hole, their tight fit provides additional stability and helps maintain the integrity of the entire structure. This reduces errors and adjustment time during installation, thus helping to lower production costs.
[0050] Preferably, the positioning insert 9 is disposed on the upper bending portion 10 of the outer plate 3. The positioning insert 9 and the outer plate 3 are integrally formed, which is convenient for processing. Multiple positioning inserts 9 are provided. All positioning inserts 9 are arranged sequentially 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 one positioning hole.
[0051] like Figure 2 As shown, the card holder is provided with a receiving groove for inserting the lower end of the outer plate 3. The receiving groove is a groove provided on the surface of the card holder facing the outer plate 3.
[0052] like Figures 4 to 6As shown, the outer panel 3 includes a first outer side wall 11, a second outer side wall 12, a third outer side wall 13, and a fourth outer side wall 14 connected in sequence. The boss 8 is welded to the first outer side wall 11. The lower end of the first outer side wall 11 is fixedly connected to one end of the second outer side wall 12. The first outer side wall 11 and the second outer side wall 12 have an included angle, which is an obtuse angle. The other end of the second outer side wall 12 is fixedly connected to the upper end of the third outer side wall 13. The second outer side wall 12 and the third outer side wall 13 have an included angle, which is an acute angle. The lower end of the third outer side wall 13 is fixedly connected to the upper end of the fourth outer side wall 14. The first outer side wall 11, the second outer side wall 12, and the fourth outer side wall 14 are located on the same side of the third outer side wall 13. The connection between the first outer side wall 11 and the second outer side wall 12 forms an upward bend 10, and the connection between the third outer side wall 13 and the fourth outer side wall 14 forms a downward bend. A single-sided buckle 5 is fixedly connected to the lower edge of the fourth outer side wall 14 (i.e., the lower edge of the outer panel 3), and the lower edge of the fourth outer side wall 14 is inserted into the receiving groove. On the outer panel 3, both the positioning insert 9 and the single-sided buckle 5 are designed at the side skirt fold, so there will be no shrinkage defects in the appearance, maintaining the aesthetics and neatness of the side skirt.
[0053] like Figures 4 to 6 As shown, the inner plate 4 includes a first inner sidewall 15, a second inner sidewall 16, a third inner sidewall 17, and a fourth inner sidewall 18 connected in sequence. A boss 8 is fixedly connected to the first inner sidewall 15. The first inner sidewall 15 is located inside the first outer sidewall 11. The lower end of the first inner sidewall 15 is fixedly connected to one end of the second inner sidewall 16. An obtuse angle exists between the first inner sidewall 15 and the second inner sidewall 16. The second inner sidewall 16 is located below the second outer sidewall 12. The second inner sidewall 16... The other end is fixedly connected to the upper end of the third inner sidewall 17. The second inner sidewall 16 and the third inner sidewall 17 have an angle between them, and the angle is acute. The third inner sidewall 17 is located inside the third outer sidewall 13. The lower end of the third inner sidewall 17 is fixedly connected to the upper end of the buckle seat 6. The lower end of the buckle seat 6 is fixedly connected to the upper end of the fourth inner sidewall 18. The fourth inner sidewall 18 is located below the outer plate 3. The first inner sidewall 15, the second inner sidewall 16 and the buckle seat 6 are located on the same side of the third inner sidewall 17.
[0054] like Figures 4 to 6 As shown, the inner panel 4 also includes a fifth inner sidewall 19 and a sixth inner sidewall 20 connected in sequence. The lower end of the fourth inner sidewall 18 is fixedly connected to the lower end of the fifth inner sidewall 19, and the upper end of the fifth inner sidewall 19 is fixedly connected to the upper end of the sixth inner sidewall 20. The sixth inner sidewall 20 is used to connect with the vehicle body. The fifth inner sidewall 19 and the sixth inner sidewall 20 are located on the same side of the fourth inner sidewall 18.
[0055] like Figures 1 to 5As shown, a trim panel fastener 2 is provided on the inner panel 4, and an upper clip 1 is installed on the trim panel fastener 2. The trim panel fastener 2 has a mounting hole for inserting the upper clip 1. The upper clip 1 is used to fix the inner panel 4 to the body, and the upper clip 1 is connected to the body by snap-fit. There are multiple trim panel fasteners 2, and all trim panel fasteners 2 are arranged sequentially along the length of the inner panel 4. Each trim panel fastener 2 has one upper clip 1. A positioning post is provided on the trim panel fastener 2, and a positioning hole is provided on the body for inserting the positioning post. The positioning post and the trim panel fastener 2 are designed as an integral part, so that a high assembly accuracy can be ensured when the side skirt is assembled with the body.
[0056] like Figures 1 to 5 As shown, the decorative panel fastener 2 is disposed on the first inner sidewall 15. The decorative panel fastener 2 adopts a through-hole structure (the mold does not need a core-pulling mechanism), which has good reliability and economy. This structure eliminates the need for a core-pulling mechanism during the mold manufacturing process, thereby simplifying the mold design and manufacturing process.
[0057] In this embodiment of the invention, the side skirt adopts a double-layer board structure composed of inner board 4 and outer board 3. In the product size inspection report, the dimensional accuracy has been improved to within 0.05%, which can be said to be a leap forward. Ensuring dimensional accuracy solves the functional problems of outer board defects and door opening and closing interference.
[0058] Secondly, embodiments of the present invention also provide a vehicle including the double-layer panel side skirt structure described above. The specific structure of this double-layer panel side skirt structure can be found in [reference needed]. Figures 1 to 6 Further details will not be elaborated here.
