Description

Technical Field

[0001] This utility model belongs to the field of automotive interior parts manufacturing technology, and specifically relates to a fully covered soft armrest grip structure. Background Technology

[0002] In the automotive interior parts manufacturing industry, soft armrests such as door armrests and center armrests are key components that drivers and passengers frequently come into contact with. The current mainstream manufacturing process is as follows: first, a rigid skeleton of the handle is formed by injection molding, then a soft layer is formed by one-piece foaming on the skeleton, and finally decorative parts such as water transfer printing, electroplating, and painting are installed by snap-fit ​​or adhesive to achieve partial coverage and beautification. However, this traditional process has many obvious defects and shortcomings: in addition to the injection mold, it is also necessary to develop a one-piece foaming mold and a decorative part mold, resulting in huge upfront equipment investment and high mold costs; decorative parts usually require additional secondary processing such as painting and electroplating, which are complicated and costly. At the same time, the overflow generated during the foaming process needs to be manually polished and cleaned, further increasing labor costs; when installing the cover, it generally relies on glue bonding, which introduces volatile organic compounds, negatively affecting the air quality inside the car, resulting in poor product odor performance and affecting the health of drivers and passengers; and due to the limitations of the process itself, the traditional structure can usually only achieve "half-coverage" or partial coverage, and cannot achieve a full coverage effect for the entire grip, resulting in poor product texture and a significant decrease in perceived quality.

[0009] Preferably, the full-coverage cover is made of soft material and has no seams on its outer surface; the inner diameter of the full-coverage cover is the same as the outer diameter of the grip assembly, and it is directly fitted onto the outer surface of the soft foam layer through an elastic interference fit.

[0010] Preferably, the soft material is leather, fabric, or synthetic leather.

[0011] The beneficial effects of this utility model are: the fully enclosed soft armrest grip structure provided by this utility model improves the durability of the product by optimizing the product hierarchy and connection method. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the fully covered soft armrest grip structure described in this utility model. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0014] like Figure 1 As shown, this utility model provides a fully enclosed soft armrest grip structure, comprising: a grip assembly, which includes: a frame 110, which serves as the load-bearing foundation for the fully enclosed soft armrest grip structure; the frame 110 is a profile formed by injection molding in one step; the material of the frame 110 is PP, ABS, or PA. In this embodiment, the frame 110 is made of ABS material. An adhesive backing layer 120 is disposed on the outer surface of the frame 110; the adhesive backing layer 120 is made of acrylic pressure-sensitive adhesive or hot melt adhesive. A soft foam layer 130 is directly adhered and fixed to the outer surface of the frame 110 through the adhesive backing layer 120; the soft foam layer 130 is made of PU foam or XPE.

[0015] The full-coverage cover 140, whose shape matches the outer profile of the grip assembly, is directly fitted onto the outer surface of the soft foam layer 130 via an elastic interference fit, achieving 360° full coverage of the grip. The full-coverage cover 140 is made of soft material and has no seams on its outer surface; the inner diameter of the full-coverage cover 140 is the same as the outer diameter of the grip assembly. The soft material can be leather, fabric, synthetic leather, or microfiber leather. Due to the elasticity and precise stitching of the full-coverage cover 140, it can tightly wrap around the outer surface of the grip assembly without any glue, forming a soft, comfortable, and aesthetically pleasing high-end armrest grip.

[0016] The manufacturing process of the fully enclosed soft armrest grip structure provided by the utility model is as follows: Step 1: According to the design requirements, ABS material is selected, and an integral rigid frame 110 is injection molded using an injection molding machine; Step 2: The soft foam layer 130 is cut according to the shape of the frame 110; pressure-sensitive adhesive or hot melt adhesive is applied to one side of the cut soft foam layer 130; the side of the soft foam layer 130 coated with the backing layer 120 is aligned with the outer surface of the frame 110, and pressed firmly to form the grip assembly; Step 3: The fully enclosed cover 140 is sewn according to the shape of the grip assembly; the pre-sewn, elastic fully enclosed cover 140, whose inner cavity shape matches the shape of the grip assembly, is directly put on the outer surface of the grip assembly like "wearing socks," creating a soft, comfortable, and aesthetically pleasing high-end armrest grip.

[0017] This utility model provides a fully enclosed soft armrest grip structure that improves product durability by optimizing product layers and connection methods; simplifies the production process, eliminating expensive dedicated molds and secondary processing steps, achieving environmentally friendly production, while comprehensively improving the product's texture and aesthetics; eliminates complex integrated foaming molds and decorative part molds, saving significant upfront mold investment; eliminates the post-foaming overflow sanding process, reducing labor costs; the fully enclosed cover is directly fitted and fixed to the outside of the grip assembly via an elastic interference fit, eliminating the need for glue bonding, saving glue costs and the time and equipment costs of glue spraying; eliminating the use of glue reduces VOC emissions in the vehicle from the source, significantly improving the product's odor, making it more environmentally friendly and healthy, and meeting the environmental protection standards for automotive interiors. Regulations require that a seamless, fully enclosed cover be used for 360° coverage, providing a soft, uniform feel throughout the grip, enhancing its overall aesthetics and premium feel, and significantly improving the product's quality to meet consumers' high-end demands for automotive interior materials. The complex processes of traditional manufacturing, including foaming, polishing, adhesive application, and snap-fitting, are simplified to three main steps: injection molding of the frame, application of the soft foam layer, and assembly of the full-coverage cover. This greatly simplifies the production process, significantly shortens the production cycle, and improves production efficiency and product quality stability. The soft foam layer is tightly bonded to the injection-molded frame with adhesive, and the full-coverage cover uses an elastic interference fit to ensure a secure connection between all components, preventing issues such as detachment, loosening, or wrinkling during long-term use, thus extending its lifespan.

[0018] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
