Moreover, there are many parts in the glass lifting system, and the installation and debugging are time-consuming and cumbersome. Specifically, the slider guide rails of the glass lifting system are generally made of metal, and the inner panel of the door needs to provide it with a mounting structure and corresponding fasteners; the seat plate / fixing frame of the motor of the glass lifting system is an independent structure, and the inner panel of the door also needs to provide it with a fixing point and corresponding fasteners. In particular, the general double-track glass lifting system has a flexible wire drawing connection between the double rails, and there is no stable integrated connection structure. Similarly, the system composed of multiple parts has a long dimensional chain for the installation of parts, which will increase the assembly error generated during the product installation and matching process. The installation and debugging will also be cumbersome and complicated, time-consuming and labor-intensive.

[0004] In addition, in a traffic accident, once a traditional sheet metal door is damaged, it is very difficult to repair or the entire door must be replaced, resulting in high repair costs for consumers. This is contrary to the important development direction of lightweight, simplified assembly, and rapid maintenance of the entire vehicle. Therefore, how to make the glass lifting system lightweight, simple assembly, rapid maintenance, and reduce product costs while meeting the normal glass lifting function is an urgent problem to be solved.

[0026] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0027] like Figure 1 As shown, an integrated composite side door system according to a preferred embodiment of the present invention comprises a composite door inner panel 1 and a window regulator 2, wherein the window regulator 2 is mounted on the composite door inner panel 1 to provide a glass lifting and window regulator system.

[0028] like Figure 2 As shown, the composite door inner panel 1 is formed by integral insert injection molding, and includes a body 10 and two guide rails 11, four guide wheel mounting points 12 and a motor seat fixing bracket (i.e., motor seat / fixing bracket) 13 integrated thereon, and the window lifting mechanism 2 is installed on the composite door inner panel 1 through the guide rail mounting points 11, the guide wheel mounting points 12 and the motor seat fixing bracket 13. Compared with the independent guide rails, guide wheel mounting points and motor seat fixing brackets connected to the metal door inner panel by fasteners in the traditional glass lifting system, the present invention integrates the guide rails 11, the guide wheel mounting points 12 and the motor seat fixing bracket 13 on the body 10 to form a composite door inner panel 1 as a complete part, without the need for an independent motor bracket, which reduces the number of parts and the use of fasteners, and at the same time contributes to the weight and cost of the product.

[0029] like Figure 3As shown, the window lifting mechanism 2 includes two glass lifting sliders 21, four guide wheels 22, a wire drawing 23 and a motor 24, wherein the glass lifting slider 21 is installed on the guide rail 11 (see Figure 2 ) and can slide along the guide rail 11, and the guide wheel 22 is rotatably mounted on the guide wheel mounting point 12 (see Figure 2 ), the wire drawing 23 is mounted on the guide wheel 22 to be guided by the guide wheel 22, and the motor 24 is mounted on the motor seat plate fixing bracket 13 (see Figure 2 ) and connected to the glass lifting slider 21 through the wire drawing 23, so that the glass lifting slider 21 is driven by the motor 24 to promote the lifting of the window glass. Since the guide rail 11, the guide wheel mounting point 12 and the motor seat plate fixing bracket 13 have been integrated on the composite material door inner panel 1, the present invention can form a new glass lifting system after the glass lifting slider 21, the guide wheel 22, the wire drawing 23 and the motor 24 are installed, providing and ensuring the lifting function of the glass in the composite material side door system.

[0030] like Figure 4 and Figure 5 As shown, an L-shaped sheet metal insert 111 is embedded in the guide rail 11 of the composite door inner panel 1. It should be understood that the sheet metal insert 111 is embedded in the composite door inner panel 1 through an integral insert injection molding process, thereby improving the rigidity of the guide rail 11 and preventing the guide rail 11 from deforming. Figure 6 As shown, the glass lifting slider 21 is installed on the guide rail 11 to provide guidance through the guide rail 11. The integrated guide rail 11 of the present invention is innovatively designed to contain a sheet metal insert 111 to enhance the rigidity and strength of the guide rail 11 and prevent the guide rail 11 from being deformed and stuck due to the weight of the glass when the glass lifting slider 21 is matched with the guide rail 11. In particular, back to Figure 4 The body 10 of the composite door inner panel 1 has a notch (also called an insert process positioning point) 10a formed in the guide rail 11 area, and the sheet metal insert 111 extends in the notch 10a to form a positioning position of the sheet metal insert 111 in the mold. In other words, each guide rail 11 is embedded with an "L"-shaped sheet metal insert 111, and each sheet metal insert 111 has two insert process positioning points 10a in the mold to ensure the accurate position of the sheet metal insert 111 during the integral injection molding.

[0031] like Figure 7 As shown, the main body 10 of the composite door inner panel 1 forms an annular flange 10b in the guide wheel mounting point 12 area, and the guide wheel 22 is rotatably mounted on the annular flange 10b through a locking rivet 22a. The wire drawing 23 is mounted in the outer groove of the guide wheel 22 and slides, thereby providing guidance for the wire drawing 23 through the guide wheel 22.

[0032] like Figure 8-Figure 9As shown, the motor seat fixing bracket 13 of the composite door inner panel 1 includes a motor mounting point 131 and a wire drawing slot 132, wherein the motor 24 is mounted on the composite door inner panel 1 through the motor mounting point 131, and the opposite ends of the wire drawing 23 are mounted through the wire drawing slot 132 to drive the movement of the wire drawing 23 through the motor 24. In addition, the motor seat fixing bracket 13 also includes a gear seat in the window lifting mechanism. The present invention fully integrates the functions of the motor seat / fixing bracket in the traditional window lifting mechanism into the composite door inner panel 1, which not only reduces the number of parts of the window lifting machine assembly, but also reduces the weight and cost of the door assembly.

[0033] The assembly state of the integrated composite material side door system according to this embodiment is described in detail below:

[0034] First, the sheet metal insert 111 and the guide rail 11 are integrated into the main body 10 of the composite door inner panel 1 by means of one-piece insert injection molding; similar to the injection molding of the composite door inner panel 1, the guide wheel mounting point 12 and the motor seat fixing bracket 13 in the window regulator are also integrated into the main body 10 of the composite door inner panel 1 by one-piece injection molding.

[0035] Next, the motor 24 is fixed to the motor base plate fixing bracket 13 , the glass lifting slider 21 is matched to the guide rail 11 , and the guide wheel 22 is rotatably mounted to the composite door inner panel 1 through the locking rivet 22 a .

[0036] Finally, the wire drawing 23 is completely arranged on the composite material vehicle door inner panel 1, and a complete glass lifting and window regulator system for the composite material side door system is formed. The final matching position and matching effect can be fine-tuned and corrected in detail after the door glass is installed, thereby providing a solution for the glass lifting in the composite material side door system.

[0037] The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The above embodiment of the present invention can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the description of the present invention fall within the scope of protection of the claims of the present invention. The contents not described in detail in the present invention are all conventional technical contents.
