Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, specifically to a corrosion-resistant synthetic leather for automotive interiors. Background Technology

[0002] Car trunks require a partition for decoration. If synthetic leather is directly bonded to the trunk's base material, it becomes inconvenient to replace or clean it when the surface is worn or has residual impurities, making it less convenient to use. If flexible materials are used to lay the car trunk, the edges may not adhere completely. Utility Model Content

[0003] Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, this utility model provides a corrosion-resistant synthetic leather for automotive interiors.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant synthetic leather for automotive interiors, comprising a composite layer, wherein the composite layer includes a wear-resistant layer, a base layer, and a bottom layer, wherein the wear-resistant layer, the base layer, and the bottom layer are connected sequentially from top to bottom, and further comprising:

[0007] The composite layer is further provided with an edge banding.

[0008] A support assembly includes a carrier bag, a sealing sheet, and a filling layer. The carrier bag is disposed below the bottom layer. The back side and both ends of the carrier bag are sewn to the bottom layer. The carrier bag and the bottom layer form a filling cavity with an opening on the front. The filling layer is adapted to the filling cavity. A sealing sheet is also disposed below the bottom layer to close the filling cavity.

[0009] To facilitate the opening and closing of the filling cavity, this utility model is improved by having the front of the sealing sheet connected to the bottom layer, a first Velcro fastener provided on the upper back side of the sealing sheet, and a second Velcro fastener provided on the lower front of the carrier bag, which is fitted with the first Velcro fastener.

[0010] Preferably, the front side of the sealing sheet is also provided with a pull ring.

[0011] Preferably, the wear-resistant layer is made of PU material.

[0012] To ensure the stability of the edge binding, this utility model is improved by providing several sets of friction blocks below the edge binding.

[0013] Preferably, the pull ring is made of silicone.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a corrosion-resistant synthetic leather for automotive interiors, which has the following beneficial effects:

[0016] The car interior uses corrosion-resistant synthetic leather. The composite layer consists of a wear-resistant layer, a base layer, and a bottom layer. When the wear-resistant layer is worn or has residual impurities, the entire composite layer can be replaced, avoiding the problem of directly bonded synthetic leather being difficult to replace and clean.

[0017] The edge banding prevents the composite layer edges from lifting, and the friction block under the edge banding increases the friction with the trunk edge, ensuring the stability of the edge banding and avoiding incomplete edge adhesion. Compared with flexible material laying, it can better guarantee the adhesion effect.

[0018] The support bag in the support assembly, together with the bottom layer, forms a filling cavity, which can be filled with different filling layers as needed to adjust the thickness and comfort of the diaphragm. The closure sheet is connected to the support bag via a first and a second Velcro strap, facilitating the opening and closing of the filling cavity and making it easy to replace or adjust the filling layer.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4A corrosion-resistant synthetic leather for automotive interiors includes a composite layer comprising a wear-resistant layer 1, a base layer 2, and a bottom layer 3, wherein the wear-resistant layer 1, the base layer 2, and the bottom layer 3 are connected sequentially from top to bottom, and further includes:

[0026] Edge banding 4, the periphery of the composite layer is also provided with edge banding 4;

[0027] The support assembly includes a carrier bag 5, a sealing sheet 6, and a filling layer 7. The carrier bag 5 is disposed below the bottom layer 3. The back side and both ends of the carrier bag 5 are sewn to the bottom layer 3. The carrier bag 5 and the bottom layer 3 form a filling cavity with an opening on the front. The filling layer 7 is adapted to the filling cavity. The sealing sheet 6 is also disposed below the bottom layer 3 to close the filling cavity.

[0028] The composite layer consists of a wear-resistant layer 1, a base layer 2, and a bottom layer 3 connected sequentially from top to bottom. The wear-resistant layer 1 is made of PU material, which, thanks to its excellent wear resistance and corrosion resistance, effectively resists friction from items inside the car trunk and the erosion of various stains and chemicals. When wear or residual impurities appear on the surface of the wear-resistant layer 1, because the composite layer is not directly bonded to the trunk substrate but rather contacts the trunk through a support component, it can be easily replaced as a whole, solving the problem of difficulty in replacing and cleaning directly bonded synthetic leather.

[0029] The back and two ends of the support bag 5 below the bottom layer 3 are sewn together with the bottom layer 3 to form a filling cavity with an opening on the front. Different filling layers 7 can be selected and placed into the filling cavity according to actual needs. The filling layers 7 can be materials with different hardness and elasticity. By filling different filling layers 7, the thickness and comfort of the spacer can be adjusted to meet the user's needs in different situations.

[0030] The front of the sealing sheet 6 is connected to the bottom layer 3, and the first Velcro 8 on the upper back side cooperates with the second Velcro 9 on the lower front of the carrier bag 5. When it is necessary to open the filling cavity to put in or take out the filling layer 7, pull the pull ring 12 on the front of the sealing sheet 6 (made of silicone material, comfortable to the touch and easy to pull) to separate the first Velcro 8 and the second Velcro 9, thus opening the filling cavity; after the filling layer 7 is placed, cover the filling cavity with the sealing sheet 6, so that the first Velcro 8 and the second Velcro 9 are attached, thereby closing the filling cavity and fixing and protecting the filling layer 7.

[0031] In actual use, the front of the sealing sheet 6 is also provided with a pull ring 12, which is made of silicone material. The pull ring 12 makes it easy to lift the composite layer with the support component.

[0032] The edging around the composite layer wraps around its edges, preventing them from lifting. Several sets of friction blocks beneath the edging increase the friction between the edging and the edge of the car's trunk. When the synthetic leather is laid in the trunk, the edging adheres tightly to the trunk edge via the friction blocks, ensuring stable edging placement and avoiding the incomplete edge adhesion that often occurs when using flexible materials. This allows the synthetic leather to be better secured inside the trunk.
