Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automotive interior parts, in particular to a starry sky roof accessory pre-embedding process. BACKGROUND

[0002] The automobile roof is a commonly used interior part of the automobile. With the increasing demand for the quality, shape and aesthetic appearance of the automobile interior part, the starry sky roof has emerged as the times require. In the production process of the automobile roof, the starry sky roof is provided as an option for customers to choose. In order to further improve the overall aesthetic appearance of the starry sky roof, the accessories on the roof, such as the light-emitting module and the control module on the starry sky roof, need to be designed as hidden as possible to avoid being exposed.

[0003] The existing starry sky roof forming process is to first form the base material and the fabric, and then assemble the accessories on the back of the roof. A series of processes such as punching, threading and trimming of the base material are required, which is complicated to operate and affects the overall strength of the roof. In addition, this back mounting structure is easy to damage the accessories when the roof is installed and disassembled, affecting the service life. SUMMARY

[0004] Based on the above problems, the purpose of the present application is to provide a starry sky roof accessory pre-embedding process, which changes the mounting form of the accessories on the roof, realizes the pre-embedding installation of the accessories, and improves the appearance and strength of the roof.

[0005] To achieve the above purpose, the following technical solutions are adopted:

[0006] A starry sky roof accessory pre-embedding process, comprising the steps of:

[0007] 1) designing a roof mold, and opening an empty slot on the mold corresponding to the accessory mounting position;

[0008] 2) placing the roof base material and the fabric into the mold for molding, and making the fabric at the accessory mounting position not adhere to the base material to form a pre-embedded interlayer;

[0009] 3) placing the accessories in the pre-embedded interlayer for assembly and installation;

[0010] 4) injecting glue into the pre-embedded interlayer to adhere the fabric and the base material again.

[0011] In particular, in step 1), the empty slot extends inward from the edge of the mold.

[0012] In particular, in step 1), the empty slot is formed on the upper mold and / or the lower mold of the mold.

[0013] In particular, in step 3), the accessories are fixed on the base material, and a window for light transmission or operation is opened on the fabric.

[0014] In particular, in step 4), the fabric and the base material of the pre-embedded interlayer are pressed by avoiding the two mold blocks of the accessory, respectively acting on the surface of the fabric and the base material.

[0015] In summary, the starry sky top accessory pre-embedding process has the advantages that compared with the prior art, the starry sky top accessory pre-embedding process forms a pre-embedded interlayer between the base material and the fabric from the perspective of modifying the mold, so as to change the installation form of the accessory on the top, and improve the appearance and strength of the top. BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 1 FIG. 1 is a schematic view of a mold with an empty slot opened on the mold in a starry sky top accessory pre-embedding process provided by an embodiment of the present application. DETAILED DESCRIPTION

[0017] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar numerals indicate the same or similar components throughout the drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0018] In the description of the present application, unless explicitly defined and limited otherwise, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, can be detachable connection, can be mechanical connection, can be electrical connection, can be direct connection, can be indirect connection through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0019] In the description of the present application, unless explicitly defined and limited otherwise, the first feature "on" or "below" the second feature can include that the first feature and the second feature are in direct contact, or that the first feature and the second feature are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0020] The technical solutions of the present application are further illustrated below in conjunction with the drawings and through specific embodiments.

[0021] The preferred embodiment provides a starry sky top accessory pre-embedding process, taking the pre-embedding of a switch variable button on a starry sky top as an example, which specifically includes the following steps:

[0022] Step 1) design a ceiling mold, and open a clearance groove 1 on the mold corresponding to the accessory installation position.

[0023] The clearance groove 1 here extends inward from the edge of the mold, and the specific position is as shown in Figure 1 The clearance groove 1 here corresponds to the button installation position on the ceiling product, and the clearance groove 1 can be formed on the upper mold or the lower mold or the upper and lower molds, which is convenient for modifying the existing mold and has low modification cost.

[0024] Step 2) place the ceiling base material and the fabric into the mold for molding, and make the fabric and the base material at the accessory installation position not fit, forming a pre-embedded interlayer.

[0025] Step 3) place the accessory in the pre-embedded interlayer and perform assembly and installation.

[0026] After assembly, the accessory is fixed on the base material to ensure reliable connection, and a window for light transmission or operation is opened on the fabric to meet the functional requirements of the accessory.

[0027] Step 4) inject glue into the pre-embedded interlayer to make the fabric and the base material fit again.

[0028] Through the two molding blocks that avoid the accessory, the fabric and the base material of the pre-embedded interlayer are pressed together, and the overall molding of the ceiling product is completed.

[0029] In summary, the above-mentioned starry sky ceiling accessory pre-embedding process forms a pre-embedded interlayer between the base material and the fabric from the perspective of modifying the mold, so as to facilitate subsequent accessory pre-embedding installation, changes the installation form of the accessories on the ceiling, and improves the appearance and strength of the ceiling.

[0030] The above examples only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above examples. Without departing from the spirit and scope of the present application, various changes and modifications can be made, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
