[0029] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0030] like Figure 1 As shown, a composite door convenient for repair and maintenance according to a preferred embodiment of the present invention comprises a composite door inner panel assembly 1 and a composite door outer panel assembly 2, wherein the composite door outer panel assembly 2 is detachably mounted and fixed on the composite door inner panel assembly 1, so as to facilitate later repair and maintenance. Figure 1 In the figure, the composite door outer panel assembly 2 is made transparent so that the structure of the covered part can be seen clearly.

[0031] Figure 2 yes Figure 1 The composite door inner panel assembly 1 is shown as an assembly diagram, wherein the composite door inner panel substrate 11 and the metal sheet metal insert assembly 12 are formed into the composite door inner panel assembly 1 by means of an integral mold insert injection molding. In other words, the composite door inner panel assembly 1 is a composite door inner panel with a metal insert formed by means of a composite insert injection molding process. The present invention completely replaces the traditional metal material door inner panel with a composite door inner panel assembly 1, and enhances the overall rigidity and strength of the door through the structural design of the inner panel substrate and the metal inserts in the necessary areas, thereby improving the load-bearing performance requirements of the door throughout the life cycle of the door, such as the weight of the door assembly system itself and the sagging of the door.

[0032] Among them, the composite door inner panel substrate 11 includes an integrally formed door inner panel lower side main body structure 111 and a door inner panel window frame structure 112. The exposed inner panel appearance surface of the integrally formed composite door inner panel substrate 11 of the present invention is no longer limited to the color of the whole vehicle like a sheet metal door or an aluminum alloy door, but can be completely independent of the whole vehicle painting process, and the color of the exposed inner panel appearance surface of the composite door inner panel substrate 11 can be customized and the appearance surface treatment can be performed as needed, for example, customizing the spraying of high-end colors different from the vehicle body color, and for example, performing leather grain paint and leather grain surface treatment. In addition, the integrally formed composite door inner panel substrate 11 of the present invention can also eliminate the appearance of welds and weld spots of the door inner panel in the window frame and the door inner panel body area, and also greatly improves the corrosion protection of the door inner panel caused by welding or paint cracking.

[0033] Figure 3 yes Figure 2Assembly schematic diagram of the metal sheet metal insert assembly 12, wherein, the door hinge area sheet metal insert 121, the door inner water cut sill (inner trim panel upper mounting skeleton area) sheet metal insert 122, the door lock B-pillar side sheet metal insert 123, the door sill sheet metal insert 124 and the window frame sheet metal insert 125 are assembled and welded to form the metal sheet metal insert assembly 12 which is integrally similar to the Chinese character "日" in shape. Combining Figure 2 , the lower parts of the door hinge area sheet metal insert 121, the door inner water cut sill sheet metal insert 122, the door lock B-pillar side sheet metal insert 123 and the door sill sheet metal insert 124 are embedded in the periphery of the main structure 111 on the lower side of the door inner panel of the composite material door inner panel substrate 11, and the upper part of the door lock B-pillar side sheet metal insert 123 and the window frame sheet metal insert 125 are embedded in the door inner panel window frame structure 112 of the composite material door inner panel substrate 11. The profiles of each independent sheet metal insert 121, 122, 123, 124, 125 of the segmented type of the present invention are completely matched with the profile of the composite material door inner panel substrate 11. In particular, the sheet metal inserts 121, 122, 123, 124, 125 with uneven or bent cross-sections having a certain strength are distributed in the door sealing surface area. This segmented sheet metal insert design can save more cost and reduce the generation of sheet metal waste compared with the integral design. In addition, this regional sheet metal insert design is more flexible, different grade metal inserts can be used in different regions, and different sheet metal insert material thicknesses can also be designed for the key performance of the necessary regions. For example, for the door hinge area sheet metal insert 121 as the key performance area, it can be strengthened as required. Figure 4 is Figure 3 Assembly schematic diagram of the door hinge area sheet metal insert 121, wherein, the hinge reinforcement plate 1212 and the limiter reinforcement plate 1213 are respectively fixedly connected to the corresponding areas of the insert substrate 1211 to form the door hinge area sheet metal insert 121. The material thickness of the insert substrate 1211 is basically the same as that of the other sheet metal inserts 122, 123, 124, 125, all being 0.7 mm, while the basic material thicknesses of the hinge reinforcement plate 1212 and the limiter reinforcement plate 1213 for local strengthening to improve the overall load-bearing requirement of the door are 2.0 mm respectively.

[0034] As Figure 5As shown, the composite door convenient for maintenance according to this embodiment also includes a door anti-collision beam 3, wherein the door anti-collision beam 3 related to safety is screwed or riveted to the corresponding position of the composite door inner panel assembly 1 by screwing or riveting, so as to provide safety protection for the composite door during static extrusion and side collision, and provide protection for the members in the car. The composite door convenient for maintenance according to this embodiment also includes a door window frame sealing plate 4 and a B-pillar trim 5, wherein the door window frame sealing plate 4 and the B-pillar trim 5 for providing the appearance surface are both bonded to the composite door inner panel assembly 1 by a bonding process. After bonding the door window frame sealing plate 4 and the B-pillar trim 5, the door window frame forms a closed cavity in the A-pillar area and the B-pillar area respectively, and the rigidity of the window frame area is improved by this structure and the installation scheme of parts, and the strength of the window frame area of ​​the door assembly under all working conditions is improved to meet the performance requirements of the door. In addition, the composite door convenient for maintenance according to this embodiment also includes a window glass guide rail 6. In this embodiment, four guide rail mounting points 11a are integrated on the composite material door inner panel substrate 11, the upper and lower ends of the front glass guide rail 6 are installed on two guide rail mounting points 11a by screws, and the upper and lower ends of the rear glass guide rail 6 are installed on the other two guide rail mounting points 11a by screws, so as to meet the installation requirements of the window glass guide rail 6 and improve the stability of the glass lifting and the door sound quality of the door glass lifting.

[0035] like Figure 6 As shown, a door accessory area 1a is formed in the middle of the composite door inner panel assembly 1, and the edge of the area is shown by a dotted frame. Compared with a traditional sheet metal door or aluminum alloy door, the door accessory area 1a is completely closed, and the closed door accessory area 1a integrates a door accessory mounting point structure, such as the front guide rail and rear guide rail in the window lifter assembly, the seat plate of the motor pulley, and the mounting point structure of the four pulleys, such as Figure 5The guide rail mounting point 11a is shown in the figure. The technical solution of the integrated door accessory mounting point structure of the door accessory area 1a complements the composite door inner panel substrate 11 and is integrally injection molded with the composite door inner panel assembly 1. In other words, the composite door inner panel assembly 1 of the present invention is different from the solution of the sheet metal door, in which the glass lifter is installed on the metal door inner panel, which requires the sheet metal door inner panel to open installation, debugging and maintenance process holes; it is also different from the door inner panel door module solution in recent years, in which the glass lifter assembly is integrated on the split plastic mounting plate. The composite door inner panel assembly 1 of the present invention reduces the number of parts in the door assembly, and at the same time has great contributions and advantages to the lightweighting and cost reduction of the entire vehicle. Specifically, the door accessory area 1a of the composite door inner panel assembly 1 of the present invention is an integrated and completely enclosed structure, without any installation and maintenance process holes on the composite door inner panel. This design provides a strong guarantee for the sealing and waterproofness of the composite door assembly system; it also innovates the maintenance strategy of the composite door system, ensuring that the inner panel of the composite door is closed and has no process holes for installation and maintenance, that is, the door accessories inside the door, such as the glass lifting module and other systems, can be maintained normally and conveniently.

[0036] Figure 7 yes Figure 1 The composite door outer panel assembly 2 includes a composite door outer panel 21, a composite door outer panel bracket 22 and a door outer water-cut window sill beam 23, wherein the composite door outer panel bracket 22 and the door outer water-cut window sill beam 23 can be made of bonding glue 8 (see Fig.10 and Fig.12 ) is bonded to the composite door outer panel 21, and the composite door outer panel bracket 22 and the door outer water-cut window sill beam 23 can also be assembled to the composite door outer panel 21 by welding to form a composite door outer panel assembly 2.

[0037] like Figure 8 As shown, the composite door inner panel assembly 1 and the composite door outer panel assembly 2 have a main structure 111 along the lower side of the door inner panel (see Figure 2 ) are arranged at twelve installation points on the periphery, and these twelve installation points include four screw installation points 1b1, 1b2, 1b3, 1b4 and eight clamping installation points 1c.

[0038] Fig. 9 is a cross-sectional view of the first screw mounting point 1b1, Fig.10 is a cross-sectional view of the second and third screw mounting points 1b2, 1b3, Fig.11This is a cross-sectional view of the fourth screw installation point 1b4. The screw installation points 1b1, 1b2, 1b3, and 1b4 can ensure the firmness of the connection between the composite door inner panel assembly 1 and the composite door outer panel assembly 2, and can also prevent the composite door outer panel assembly 2 from falling off, and also have an anti-theft effect. Fig. 9 In the door hinge area sheet metal insert 121 (see Figure 2 and Figure 3 ) is embedded in the composite door inner panel substrate 11, and the anti-theft screw 7 penetrates the composite door inner panel substrate 11, the door hinge area sheet metal insert 121 and the door outer water-cut window sill beam 23 to fasten the composite door outer panel assembly 2 to the composite door inner panel assembly 1. Fig.10 In the embodiment, the composite door outer panel bracket 22 is bonded to the composite door outer panel 21 by bonding glue 8, the door sill sheet metal insert 124 is embedded in the composite door inner panel substrate 11, and the anti-theft screw 7 is set through the composite door inner panel substrate 11, the door sill sheet metal insert 124 and the composite door outer panel bracket 22 to fasten the composite door outer panel assembly 2 to the composite door inner panel assembly 1. Fig.11 In the door lock B-pillar side sheet metal insert 123 (see Figure 2 and Figure 3 ) is embedded in the composite door inner panel substrate 11, and the anti-theft screw 7 is arranged through the composite door inner panel substrate 11, the door lock B-pillar side sheet metal insert 123 and the door outer water-cut window sill beam 23 to fasten the composite door outer panel assembly 2 to the composite door inner panel assembly 1.

[0039] Fig.12 It is a cross-sectional view of the clamping installation point 1c. The composite door outer panel bracket 22 is bonded to the composite door outer panel 21 by bonding glue 8. The composite door outer panel bracket 22 has an adaptive and detachable mushroom nail buckle 9 extending toward the composite door inner panel assembly 1. The metal sheet metal insert assembly 12 is embedded in the composite door inner panel substrate 11. The mushroom nail buckle 9 is clamped and installed with the composite door inner panel substrate 11. In addition, the composite door outer panel bracket 22 can also have a cross positioning pin with a guide structure at the top to facilitate the positioning and normal assembly of the composite door outer panel bracket 22 and the composite door outer panel assembly 2 on the composite door inner panel assembly 1.

[0040] like Figure 9-12As shown, the edge regions of the composite door inner panel assembly 1 and the composite door outer panel assembly 2 are provided with sealing rubber cotton 10, which is adhered to the edge of the composite door outer panel assembly 2. When the composite door outer panel assembly 2 is assembled to the composite door inner panel assembly 1, the sealing rubber cotton 10 adhered to the composite door outer panel assembly 2 is solidified to form a semicircular sealing foam with certain elasticity and viscosity. At the same time, as the assembly force of the composite door inner panel assembly 1 is applied by screwing and clamping, the semicircular sealing rubber cotton 10 will be compressed into a long flat oval shape, and while being compressed, it is also adhered to the edge of the composite door inner panel assembly 1, so as to achieve the effect of sealing and firmly connecting the composite door inner and outer panels.

[0041] The following describes the assembly process of the composite door according to this embodiment:

[0042] First, a composite door inner panel assembly 1 and a composite door outer panel assembly 2 are provided respectively. The composite door inner panel assembly 1 is injection molded by a one-piece mold insert from a composite door inner panel substrate 11 and a metal sheet metal insert assembly 12. In particular, the injection molded composite door inner panel assembly 1 has a completely enclosed door accessory area 1a (without any debugging and maintenance process holes), and the door accessory area 1a is integrated with a door accessory mounting point structure, such as the front guide rail and rear guide rail of the glass lift assembly, the seat plate of the motor pulley, and the mounting point structure of four pulleys. The composite door outer panel bracket 32 ​​and the door outer water-cut window sill beam 33 are installed on the composite door outer panel 21 to form a composite door outer panel assembly 2.

[0043] Then, the window glass guide rail 6 is screwed to the guide rail mounting point 11a of the door accessory area 1a of the composite door inner panel assembly 1, and the door anti-collision beam 3 is screwed to the composite door inner panel assembly 1. In addition, the door accessories such as the door hinge, the stopper, the motor, the pulley, the lifting sliding bracket, the winding wheel accessories in the glass lifter, the glass sealing strip, the glass, the door lock, the wiring harness, etc. are installed on the composite door inner panel assembly 1 through the integrated mounting point structure.

[0044] Finally, the composite door outer panel assembly 2 is clamped to the composite door inner panel assembly 1 by eight mushroom nail clips 9 through the clamping installation point 1c, and then four anti-theft screws 7 are screwed to the composite door inner panel assembly 1 through the screw installation points 1b1, 1b2, 1b3, and 1b4. The edge matching area of ​​the composite door outer panel assembly 2 and the composite door inner panel assembly 1 is sealed with sealing cotton 10 to achieve the overall sealing performance of the composite door, thereby forming a complete composite door that is easy to repair and maintain.

[0045] When the composite door with convenient maintenance according to the present invention is debugged and calibrated before leaving the factory, or when the door is damaged by a collision when used by the final end customer and needs maintenance, it is only necessary to remove the four anti-theft screws 7, separate the clamping structure of the eight mushroom nail buckles 9, and slightly process the sealing cotton 10 that adheres the composite door outer panel assembly 2 to the composite door inner panel assembly 1, so that the door accessories on the inside of the door system can be conveniently maintained. Similarly, if the composite door outer panel assembly 2 is damaged to the point of being unusable, the composite door outer panel assembly 2 can be directly replaced, which completely avoids the pain point of expensive maintenance costs caused by the need to directly replace the entire door assembly for traditional metal doors, and provides a more complete solution for the user's car experience and car maintenance costs.
