[0019] The edges of the inner side and the outer side of the skeleton plate 2 are provided with a protruding structure 4, which is integrally connected with the skeleton plate 2 and is integrally injection molded, thereby ensuring the stability and integrity of the structure. In this embodiment, the protruding structure 4 on the inner side of the skeleton plate 2 is distributed along the edge of the inner side of the skeleton plate 2, and the protruding structure 4 on the outer side of the skeleton plate 2 is distributed along the edge of the outer side of the skeleton plate 2.

[0020] The outer side of the protruding structure 4 is flush with the corresponding edge side of the skeleton plate 2.

[0021] The protruding structure 4 on the outer side of the skeleton plate 2 forms a mounting groove, and the protruding structure 4 on the inner side of the skeleton plate 2 forms a recess.

[0022] The 3D MESH layer 3 is arranged in the mounting groove, and the protruding structure 4 on the inner side of the skeleton plate 2 corresponds to the edge protrusion of the glove box inner plate 5, which is used to enhance the structural strength of the entire skeleton structure, thereby improving the structural strength of the entire glove box outer plate.

[0023] The protruding structure 4 on the inner side of the skeleton plate 2 and the edge protrusion of the glove box inner plate 5 can form a gap for the skin 1 to pass through.

[0024] The thickness of the 3D MESH layer 3 is greater than the depth of the mounting groove, and the difference between the thickness of the 3D MESH layer 3 and the depth of the mounting groove is 0.05mm-0.15mm, preferably 0.1mm.

[0025] In this embodiment, the depth of the mounting groove is 2.9mm, and the thickness of the 3D MESH layer 3 is 3mm.

[0026] It can be understood that those skilled in the art can determine the thickness of the 3D MESH layer 3 and the depth of the mounting groove according to the soft touch position requirements, which can be determined by using the existing technology, and will not be described in detail here.

[0027] After the 3D MESH layer 3 is fixed into the mounting groove, it, together with the skeleton plate 2 and the protruding structure 4 integrally arranged on the skeleton plate 2, forms a skeleton structure, and the outer side of the skeleton structure is covered with the skin 1.

[0028] In this embodiment, the skin 1 is made of PVC or PU, and the thickness of the skin 1 is 0.5-1.5mm, preferably 1mm. Such thickness can ensure the strength of the skin 1, and avoid the gap between the edge of the glove box outer plate and the surrounding structure not meeting the requirements due to excessive thickness.

[0029] It can be understood that the thickness of the skin 1 can be set by those skilled in the art according to actual needs, which is not described in detail here.

[0030] The skin 1 covers the outer surface of the 3D MESH layer 3 and the outer surface of the protruding structure 4 on the outer side of the skeleton plate 2, and the edge of the skin 1 is provided with a bending towards the inner side, wherein the bending includes a first bending part, a second bending part and a third bending part.

[0031] The first bending part covers the edge of the outer side of the skeleton structure, the second bending part covers the outer surface of the protruding structure on the inner side of the skeleton plate 2, and the third bending part covers the edge of the bottom surface of the groove formed by the protruding structure 4 on the inner side of the skeleton plate 2.

[0032] The second bending part passes through the gap between the protruding structure 4 on the inner side of the skeleton plate 2 and the edge protrusion of the glove box inner plate 5.

[0033] In this embodiment, the skin 1 is bonded and fixed with the skeleton structure, and the protruding structure 4 on the inner side of the skeleton plate 2 increases the structural strength of the skeleton structure and increases the bonding area of the skin 1 and the skeleton structure, thereby increasing the fixing strength of the skin 1 and the skeleton structure.

[0034] The glove box outer plate of this embodiment is used for the edge side of the instrument panel, only covered with the skin 1 without the foaming layer, the compression amount of the skin 1 is easy to control, the consistency is easy to ensure, thereby the overall contour of the glove box outer plate is not easy to exceed the tolerance, which is convenient for subsequent assembly with the surrounding instrument panel parts, improves the matching qualification rate of the overall glove box outer plate, and through the setting of the 3D MESH layer 3, the soft touch of the appearance of the glove box is ensured, and the user's experience is improved.

[0035] Embodiment 2 The embodiment provides a manufacturing method of the glove box outer plate of embodiment 1, which comprises the following steps: Step 1: integrally injection molding the skeleton plate 2 and the protruding structure 4 on the edge of the inner side and the outer side, which can use the prior art injection molding process, and the specific method is not described in detail here. The injection molding parameters such as temperature, pressure and time need to be strictly controlled to ensure the quality and dimensional accuracy of the skeleton plate 2 and the protruding structure 4.

[0036] Step 2: Cut the 3D MESH material according to the size of the installation groove formed on the outer side of the skeleton plate 2 to obtain a 3D MESH layer 3 matching the size of the installation groove. During the cutting process, attention should be paid to keeping the edges of the 3D MESH layer 3 smooth to avoid burrs or deformation.

[0037] Step 3: Spray glue on the side and bottom surfaces of the installation groove, and spray glue on the surface of the 3D MESH layer 3 used to cooperate with the installation groove.

[0038] In this embodiment, the glue spraying thickness is 0.05mm-0.15mm, preferably 0.1mm. It can be understood that the person skilled in the art can set the glue spraying thickness according to the actual needs, which will not be described in detail here.

[0039] The glue spraying needs to uniformly cover the entire surface to avoid missing spraying or uneven thickness.

[0040] Step 4: Place the 3D MESH layer 3 into the installation groove and bond and fix the 3D MESH layer 3 with the side and bottom surfaces of the installation groove to form the entire skeleton structure.

[0041] During the installation of the 3D MESH layer 3, attention should be paid to avoid wrinkles or displacement of the 3D MESH layer 3 to ensure its flatness and fixing strength.

[0042] Step 5: Spray glue on the surface of the skin 1 used to paste the skeleton structure, and spray glue on the skin covering surface of the skeleton structure.

[0043] In the skeleton structure, the covering surface of the skin 1 includes the outer side of the 3D MESH layer 3, the top surface of the outer side protruding structure 4 of the skeleton plate 2, the edge side of the skeleton structure, the surface of the inner side protruding structure 4 of the skeleton plate 2, and the bottom surface edge of the groove used to cooperate with the skin 1.

[0044] The glue spraying thickness is 0.05mm-0.15mm, preferably 0.1mm. It can be understood that the person skilled in the art can set the glue spraying thickness according to the actual needs, which will not be described in detail here.

[0045] Step 6: Bond and fix the skin 1 with the outer side of the 3D MESH layer 3, fold the edges of the skin 1 to form a first bending part, a second bending part and a third bending part, wherein the first bending part is bonded and fixed with the outer side of the edge of the skeleton structure, the second bending part is bonded and fixed with the surface of the protruding structure 4 of the inner side of the skeleton plate 2, and the third bending part is bonded and fixed with the bottom surface edge part of the groove.

[0046] After the skin 1 is firmly bonded on the skeleton structure, the entire glove box outer plate is completed.

[0047] In this embodiment, the third bending part of the skin 1 is only bonded and fixed with the edge part of the groove, and the third bending part of the skin 1 is fixed with the edge part of the groove, so that the skin 1 does not affect the assembly and fixation between the inner plate 5 and the outer plate of the glove box. When the glove box outer plate of this embodiment is used, the inner plate of the glove box and the remaining structure do not need to be changed, the improvement is convenient, and the improvement cost is low.
