[0049] The following is combined with Figure 1-6 This application is described in further detail.

[0050] The present application embodiment provides a luggage compartment side trim panel, such as Figure 1 and Figure 2 As shown, it includes a side trim body 10, one side of the side trim body 10 is recessed outward to form a receiving groove 13 for receiving items to be stored, and the outward here refers to the direction toward the automobile sheet metal.

[0051] In order to form a receiving groove 13 with a larger space (a receiving groove 13 with a larger space refers to a receiving groove 13 with a groove depth greater than 200 mm), the side trim body 10 in this embodiment is composed of a PET bottom felt layer 11 and a carpet surface layer 12. The PET material has a strong tensile strength, and the carpet surface layer 12 is a needle-punched carpet surface. At the same time, the side wall of the receiving groove 13 is specially designed with a first arc surface 111 and a second arc surface 112 connected. Among them, the first arc surface 111 is closer to the center of the side trim body 10, while the second arc surface 112 is relatively far away. In particular, the arc radius of the second arc surface 112 is controlled between 20cm and 40cm. It is matched with the PET material of the side trim body 10. Under the double-layer combination of its process and material, the side trim body 10 is not easy to be torn when forming a receiving groove 13 with a larger stretching distance, so that a side trim with better quality can be formed and a receiving groove 13 with a larger space can be formed.

[0052] Reference Figure 3 and Figure 4The luggage compartment side trim also includes a sealing plate 20, a cushioning airbag 30 and an airbag air supply device 40. The sealing plate 20 is rotatably connected to the groove wall of the receiving groove 13, and the sealing plate 20 can enclose the groove wall of the receiving groove 13 to form a closed space 50 to ensure the isolation and protection of the internal items. The cushioning airbag 30 is arranged in the closed space 50, and a storage cavity 31 is provided in the center thereof for directly storing items to be stored, such as ceramics, wine bottles, medicine bottles, etc. The airbag air supply device 40 is arranged in the receiving groove 13 and is connected to the sealing plate 20 and the cushioning airbag 30. When the sealing plate 20 rotates back and forth under the action of external force, the cushioning airbag 30 can be inflated through the airbag air supply device 40, thereby adjusting the size of the storage cavity 31 to meet the storage needs of different items.

[0053] Figure 1 What is shown separately in the figure is a schematic diagram of the luggage compartment side trim, in which the cushion airbag 30 and the airbag air supply device 40 appear to be suspended in the air. In fact, after the luggage compartment side trim is assembled with the automobile sheet metal, the automobile sheet metal will form a bottom plate under the cushion airbag 30 and the airbag air supply device 40, and the cushion airbag 30 and the airbag air supply device 40 are supported by the bottom plate.

[0054] Reference Figure 3 and Figure 4 In this embodiment, the sealing plate 20 is composed of a first sealing plate 21 and a second sealing plate 22. The first sealing plate 21 is rotatably connected to the groove wall of the receiving groove 13 through a rotating shaft 421, and the other side of the first sealing plate 21 away from the rotating shaft 421 is hinged to the second sealing plate 22 through a hinge or other means, so that the two can be folded or unfolded relative to each other. When the first sealing plate 21 and the second sealing plate 22 are in a closed state, their peripheral sides can be tightly abutted against the groove wall of the receiving groove 13, thereby forming a complete closed space 50.

[0055] In order to enhance the sealing effect, the sealing plate 20 is also provided with filling cotton 23 around its side, which can effectively fill possible gaps and prevent the intrusion of external air or moisture. In addition, after the closed space 50 is formed, the upper surface of the second sealing plate 22 can also support items, thereby further making full use of the space.

[0056] Specifically, the airbag air supply device 40 further includes a cylinder piston structure 41 and a transmission assembly 42. The cylinder piston structure 41 is installed in the receiving groove 13, and its function is to provide a one-way inflation function to the cushion airbag 30. The cylinder piston structure 41 is a common cylinder piston structure 41 on the market, and its structural principle is not described here.

[0057] Reference Figure 3 and Figure 5The transmission assembly 42 is arranged between the sealing plate 20 and the cylinder piston structure 41, and is composed of a rotating shaft 421, a lever 422 and a transmission rod 423. The rotating shaft 421 is installed at the connection between the sealing plate 20 and the wall of the receiving groove 13, so that the sealing plate 20 can rotate with the shaft as a fulcrum. The lever 422 is connected to one end of the rotating shaft 421 and is eccentrically arranged with the rotating shaft 421, so that when the rotating shaft 421 reciprocates, the lever 422 can produce a reciprocating swinging motion. Figure 4 and Figure 5 The transmission rods 423 are fixed at the input end of the cylinder piston structure 41, and at least two are provided to ensure the stability of the transmission. The lever 422 and the opposite side wall of the adjacent transmission rod 423 are in sliding contact, so that the rotation of the sealing plate 20 can be converted into the linear reciprocating motion of the transmission rod 423 through the lever 422, thereby driving the cylinder piston structure 41 to perform the inflation operation.

[0058] Reference Figure 4 In addition, a cushioning cotton 24 is also provided on the inner side of the second sealing plate 22 facing the enclosed space 50. This layer of cushioning cotton 24 can provide additional shock-absorbing protection for the items stored in the cushioning airbag 30, preventing the items from being damaged due to bumps during transportation.

[0059] Reference Figure 3 and Figure 4 At the same time, a limiting plate 60 is also arranged between the first sealing plate 21 and the buffer airbag 30, and the limiting plate 60 is fixedly connected to the groove wall of the receiving groove 13. The main function of the limiting plate 60 is to limit the movement range of the buffer airbag 30 during the inflation process, ensure the stability of its position, thereby ensuring the effective formation of the storage cavity 31 and the safe storage of articles.

[0060] In addition, the present embodiment further adds a partition 70 in the receiving groove 13. The main function of the partition 70 is to physically separate the airbag air supply device 40 from the cushion airbag 30. The airbag air supply device 40 and the cushion airbag 30 are connected by an air pipe, and the air pipe runs through the partition 70 to ensure that the two work normally in their own independent spaces.

[0061] At the same time, the side of the partition 70 is designed with an abutment structure that matches the surface of the sealing plate 20. When the sealing plate 20 is closed, the side of the partition 70 can fit tightly with the surface of the sealing plate 20, thereby forming an independent closed space 50 between the partition 70, the sealing plate 20 and the groove wall of the receiving groove 13. This design not only improves the sealing performance of the overall structure, but also effectively isolates the noise and heat that may be generated by the airbag air supply device 40, providing a quieter and more stable storage environment for the items stored in the cushioning airbag 30.

[0062] In addition, the structure of the cushioning airbag 30 is also optimized. In particular, the cushioning airbag 30 can expand and extend along its height direction and along the center direction of the storage cavity 31 when inflated. The principle of this is that the shape of the cushioning airbag 30 is pre-designed and determined at the beginning of production, so that it can expand in a predetermined direction when inflated. This multi-directional expansion capability allows the cushioning airbag 30 to more flexibly adapt to objects of different shapes and sizes, thereby providing a wider range of applicability.

[0063] In addition, the cushioning airbag 30 is also equipped with a deflation valve 80. When it is necessary to quickly deflate the air to adjust the size of the storage cavity 31 or take out items, the operator only needs to lightly turn the deflation valve 80 to quickly discharge the gas in the cushioning airbag 30, which greatly improves the convenience of use.

[0064] The implementation principle of this embodiment is that by comprehensively using the sealing plate 20, the cushioning airbag 30 and the airbag air supply device 40 and other components, the items stored in the luggage compartment are effectively fixed, shock-absorbed and sealed. This design not only solves the problem of the single function of the traditional luggage compartment side trim, but also significantly improves the safety and protection of the items during transportation. At the same time, by adding a partition 70 and optimizing the structure of the cushioning airbag 30, the sealing of the overall structure and the convenience of use are further enhanced, meeting the diverse needs of users for the luggage compartment storage environment.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
