SUMMARY

[0003] The utility model aims at providing a kind of automobile armrest framework foaming structure, and the technical problems of poor sealing effect, face cover and framework easy to fall off and complex operation in prior art are solved.

[0004] The utility model relates to a kind of automobile armrest framework foaming structure, including framework, face cover, foaming layer, foaming layer is arranged between framework and face cover;

[0005] The left side, front side and rear side of framework are respectively provided with framework bending section, the lower side of framework bending section is provided with recess, the left side, front side and rear side of face cover are respectively provided with one face cover bending section, any one face cover bending section is respectively sewn with one rubber strip, face cover bending section and rubber strip are inserted into the recess of framework, rubber strip is composed of a thin strip and a thick strip, thick strip is located inside thin strip, and the width of thick strip is greater than thin strip, the upper side of thin strip is sewn with the lower side of face cover bending section, buckle is provided on the lower side of recess outside thick strip, and buckle is connected with the lower part of thick strip;

[0006] The right side of framework is provided with first sealing edge, and the right side of face cover is provided with second sealing edge, and the upper side of first sealing edge is matched with the lower side of second sealing edge.

[0007] Further, one end of the thin strip is connected to the middle of one end surface of the thick strip.

[0008] Compared with existing technologies, this invention offers positive and significant advantages. By improving the sealing method, this invention employs different sealing styles depending on the location of the product structure. After the faceplate and rubber strip are sewn together, it is inserted into the groove of the skeleton. The clips in the skeleton groove hold the rubber strip in place, while the silicone strip compresses the faceplate, achieving a good seal between the faceplate and the skeleton. Furthermore, the rubber strip is not completely sealed to the skeleton, allowing gas generated during the foaming process to escape between them, ensuring both minimal leakage and good venting. The rubber strip is sewn together and directly inserted into the skeleton, simplifying the operation, providing a more stable structure, preventing the faceplate from easily detaching from the skeleton, reducing the need for manual operation, and improving production efficiency.

[0019] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0020] like Figures 1-10 As shown, the present invention provides a car armrest frame foam structure, including a frame 1, a cover 2, and a foam layer 3, wherein the foam layer 3 is disposed between the frame 1 and the cover 2.

[0021] The left, front, and rear sides of the skeleton 1 are respectively provided with skeleton bending sections 4, and the lower side of the skeleton bending section 4 is provided with a groove 5. The left, front, and rear sides of the mask 2 are respectively provided with a mask bending section 6. Each mask bending section 6 is sewn with a rubber strip 7. The mask bending section 6 and the rubber strip 7 extend into the groove 5 of the skeleton 1. The rubber strip 7 is composed of a thin strip 8 and a thick strip 9. The thick strip 9 is located inside the thin strip 8 and the width of the thick strip 9 is greater than that of the thin strip 8. The upper side of the thin strip 8 is sewn to the lower side of the mask bending section 6. The lower side of the groove 5 is provided with a buckle 10 outside the thick strip 9, and the buckle 10 is engaged with the lower part of the thick strip 9.

[0022] The right side of the frame 1 is provided with a first sealing edge 11, and the right side of the faceplate 2 is provided with a second sealing edge 12. The upper side of the first sealing edge 11 and the lower side of the second sealing edge 12 are engaged.

[0023] Furthermore, one end of the thin strip 8 is connected to the middle of one end face of the thick strip 9.

[0024] Specifically, in this embodiment, the skeleton 1, the faceplate 2, the foam layer 3, the rubber strip 7, the buckle 10, etc., all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0025] The molding process of this utility model is as follows: The bent section 6 of the face cover is sewn together with the rubber strip 7. The bent section 6 of the face cover and the rubber strip 7 are inserted into the groove 5 of the skeleton 1. The rubber strip 7 seals the left, front and back sides of the face cover 2 and the skeleton 1. The silicone strip 15 is inserted into the fixed mold 13. The face cover 2 and the skeleton 1 are placed in the mold. The compressibility of the silicone strip 15 makes the face cover 2 and the skeleton 1 fit tightly to achieve the right side sealing effect. The moving mold 14 and the fixed mold 13 are closed. The raw material is injected into the foaming material through the sprue sleeve 16 on the moving mold 14 or the fixed mold 13. After curing, the foaming layer 3 is formed, and the product is obtained.

[0026] The utility model discloses an improved sealing mode, and different sealing styles are adopted according to different positions of product structure. After the face cover 2 is sewn with the rubber strip 7, the face cover 2 is inserted into the recess 5 of the framework 1, the buckle 10 in the recess 5 of the framework 1 buckles the rubber strip 7, and meanwhile the silica gel strip 15 extrudes the face cover 2, so that better sealing effect is achieved between the face cover 2 and the framework 1, and the rubber strip 7 and the framework 1 are not completely sealed, and the gas generated in the foaming process can be discharged from the rubber strip 7 and the framework 1, so that the production efficiency is improved.
