Description

Technical Field

[0001] The utility model relates to the field of automobile accessories production, in particular to an integrated foaming structure of an automobile interior door armrest. Background Art

[0002] At present, most handrails are vacuum compounded or manually coated. The surface is made of PVC leather, PU, ​​genuine leather, etc., and the frame is injection molded ABS. There is a foaming layer between the surface and the frame to improve the soft touch. The surface is compounded on the foamed frame by spraying glue. The process is as follows: put the injection molded ABS frame into the foaming machine for foaming. After foaming, automatically or manually spray glue on the surface of the product, and also spray glue on the surface. Finally, the surface is bonded to the foamed frame by vacuum compounding or manual compounding, and finally the edge is automatically or manually wrapped.

[0003] However, the above process requires spraying a large amount of glue for compounding, which wastes a lot of glue, generates unnecessary waste, pollutes the environment, and is harmful to the human body. Utility Model Content

[0004] In order to solve the technical problems raised in the background technology, the utility model proposes an integrated foaming structure for automobile interior door armrests which eliminates the glue spraying process and the coating process, reduces costs, reduces environmental pollution and reduces harm to the human body.

[0005] The technical solution of the utility model is an integrated foaming structure of an automobile interior door armrest, comprising a skin, a foaming layer and a frame; the frame is connected to the skin and an injection cavity is formed between the skin, and the frame has a feed port connected to the injection cavity; the foaming layer is filled in the injection cavity through the feed port.

[0006] Preferably, the injection cavity thickness is 5 mm.

[0007] Preferably, the epidermis has a snap-fit ​​portion, and the frame has an undercut portion snap-fitted to the snap-fit ​​portion.

[0008] Preferably, the surface of the skin facing the frame is a bonding surface.

[0009] Preferably, the surface layer is made of TPE material and the foaming layer is made of polyurethane material.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model eliminates the glue spraying process and the coating process, reduces the cost, reduces environmental pollution, and reduces the harm to the human body. After the frame and the skin are assembled together, the assembled structure is placed in a foaming machine for foaming, and the polyurethane foam material enters the injection cavity through the feed port until the injection cavity is filled, completing the production of the entire handrail.

[0014] In the figure: 1, skin; 11, buckle part; 2, foaming layer; 3, skeleton; 31, undercut part. DETAILED DESCRIPTION

[0015] like Figure 1 and Figure 2 As shown, the utility model provides an integrated foam structure for an automobile interior door armrest, comprising a surface skin 1, a foam layer 2 and a frame 3.

[0016] The skeleton 3 is connected to the skin 1, and an injection cavity is formed between the skeleton 3 and the skin 1. The thickness of the injection cavity is 5 mm, which is the thickness of the final foaming layer 2. The skeleton 3 has a feed port connected to the injection cavity. The skeleton 3 and the skin 1 are pre-assembled together.

[0017] The foaming layer 2 is filled into the injection cavity through the feed port, and the foaming layer 2 is made of polyurethane.

[0018] The skin 1 is made of TPE material, and the surface of the skin 1 facing the frame 3 is the bonding surface. The bonding surface of the skin 1 needs to be flame treated to increase the surface tension of the TPE skin so that the skin 1 and the foaming material can be bonded. The skin 1 has a buckle portion 11, and multiple buckle portions 11 are arranged along the edge of the skin 1. The frame 3 has an undercut portion 31 that is buckled with the buckle portion 11, and multiple undercut portions 31 are correspondingly arranged along the edge of the frame 3. Through the buckle connection between the buckle portion 11 and the undercut portion 31, the skin 1 and the frame 3 can be firmly connected to ensure the sealing of the assembly structure and prevent the foaming material from overflowing when the foaming material is injected.

[0019] The utility model eliminates the glue spraying process and the coating process, reduces the cost, reduces environmental pollution, and reduces the harm to the human body. After the frame 3 and the skin 1 are assembled together, the assembled structure is placed in a foaming machine for foaming, and the polyurethane foam material enters the injection cavity through the feed port until the injection cavity is filled, completing the production of the entire handrail.

[0020] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
