[0028] See also Figures 1 to 4 Now, a composite material vehicle door inner panel subassembly provided by the utility model is described. A composite material vehicle door inner panel subassembly comprises a vehicle door inner panel 100, a hinge reinforcement plate 300 and a lock mounting plate 400. The upper portion of the vehicle door inner panel 100 is provided with a window structure 110. The inner side of the vehicle door inner panel 100 is provided with an upper window frame 200 having a hollow chamber. The upper window frame 200 is arranged around the circumference of the window structure 110. The hinge reinforcement plate 300 and the lock mounting plate 400 are located at the lower portion of the vehicle door inner panel 100. The hinge reinforcement plate 300 is installed at the inner front end of the vehicle door inner panel 100, and the lock mounting plate 400 is installed at the inner rear end of the vehicle door inner panel 100. The vehicle door inner panel 100 and the upper window frame 200 are made of carbon fiber materials, and the hinge reinforcement plate 300 and the lock mounting plate 400 are made of aluminum alloy materials.

[0029] The utility model provides a composite vehicle door inner panel subassembly. Compared with the prior art, the hinge reinforcement plate 300 and the lock mounting plate 400 are respectively mounted on the inner side of the lower part of the vehicle door inner panel 100, and the upper window frame 200 is arranged on the circumferential inner side of the window structure 110 on the upper part of the vehicle door inner panel 100. The upper window frame 200 has a hollow chamber inside. Among them, the vehicle door inner panel 100 and the upper window frame 200 are made of carbon fiber materials, and the hinge reinforcement plate 300 and the lock mounting plate 400 are made of aluminum alloy materials. The composite vehicle door inner panel subassembly provided by the utility model adopts carbon fiber materials and aluminum alloy materials, and has a lighter overall weight, can effectively reduce the vehicle curb weight, and can significantly improve fuel efficiency.

[0030] Among them, the door inner panel 100 is a main component inside the car door. It not only plays a decorative role, but also bears the functions of protecting the internal structure, providing storage space, installing the door control system and improving riding comfort. The hinge reinforcement plate 300 is a structural member used to strengthen the hinge part of the car door, which is usually made of high-strength steel plate material. The function of the hinge reinforcement plate 300 is to improve the bearing capacity and stability of the door hinge, reduce the deformation and looseness of the door caused by long-term use or impact, so as to ensure the safety and service life of the door. The lock installation plate 400 refers to a plate used to install and fix the door lock inside the car door inner panel 100.

[0031] At the same time, the carbon fiber material itself has the characteristics of high rigidity and high toughness. When the upper window frame 200 with a hollow chamber is arranged around the window structure 110, the carbon fiber is pressed against the mold cavity wall by an inflation bag or a filling foam process around the carbon fiber during laying, and the hollow chamber structure is formed by autoclave curing. The hollow chamber structure forms a stable upper window frame 200, which can further improve the rigidity of the single door inner panel 100. The hollow chamber can also improve the sound insulation ability and effectively reduce the noise of the door. The upper window frame 200 forms a stable frame structure, which can greatly improve the rigidity of the window structure 110. The door inner panel 100 and the upper window frame 200 are bonded to form a door inner panel sub-assembly, which can meet the requirements of the assembly in bending, torsion, corner warping and other working conditions. In the whole vehicle state, it can effectively overcome the reaction force of the sealing strip and the buffer block to cause the door to deform, and can ensure that the appearance surface difference is flat, the appearance is exquisite, and the texture of the whole vehicle is improved.

[0032] When the vehicle shape is more sharp, the requirements of structural molding can be met. Even considering the installation structure of accessories, there is no need to process them separately. The parts have a strong sense of integrity, a refined inner surface, a strong ability to adapt to the shape, and a wide range of molding.

[0033] See also Figure 1 and Figure 3 A first overlapping surface 211 is provided on the lower front side of the inner side surface of the upper window frame 200, and the upper end of the hinge reinforcement plate 300 overlaps the first overlapping surface 211. A second overlapping surface 221 is provided on the lower rear side of the inner side surface of the upper window frame 200, and the upper end of the lock mounting plate 400 overlaps the second overlapping surface 221.

[0034] Specifically, the hinge reinforcement plate 300 is conformably attached to the inner front end of the door inner panel 100 and fixed by riveting, and the lock installation plate 400 is conformably attached to the inner rear end of the door inner panel 100 and fixed by riveting. The upper end of the hinge reinforcement plate 300 is tilted inwardly and finally overlapped on the first overlap surface 211. The upper end of the hinge reinforcement plate 300 and the first overlap surface 211 form mutually adapted overlap planes, which can improve the structural stability of the hinge reinforcement plate 300. At the same time, the upper end of the hinge reinforcement plate 300 and the first overlap surface 211 can be further fixed by welding or riveting to further improve the stability of the hinge reinforcement plate 300. Similarly, the upper end of the lock installation plate 400 is tilted inwardly and finally overlapped on the second overlap surface 221. The upper end of the lock installation plate 400 and the second overlap surface 221 form mutually adapted overlap planes, which can improve the structural stability of the lock installation plate 400. At the same time, the upper end of the lock installation plate 400 and the second overlapping surface 221 can be further fixed for a second time by welding or riveting, so as to further improve the stability of the lock installation plate 400.

[0035] The first connector 210 is disposed at the bottom of the front side of the upper window frame 200, and the front side of the first connector 210 forms a first overlap surface 211. The second connector 220 is disposed at the bottom of the rear side of the upper window frame 200, and the front side of the second connector 220 forms a second overlap surface 221. The first connector 210 and the second connector 220 are both trapezoidal plate structures, and the inner side of the trapezoidal plate structure forms a cavity, and the bottom width is smaller than the top width, and the cavity is connected to the hollow chamber of the upper window frame 200. The inner side of the first connector 210 and the inner side of the second connector 220 respectively form a first overlap surface 211 and a second overlap surface 221, so as to respectively adapt to the upper end of the hinge reinforcement plate 300 and the upper end of the lock mounting plate 400.

[0036] Specifically, the first overlap surface 211 and the second overlap surface 221 are both lower than the inner side surface of the upper window frame 200. The first overlap surface 211 and the inner side surface of the upper window frame 200 form a step structure, and similarly, the second overlap surface 221 and the inner side surface of the upper window frame 200 also form a step structure. When the upper end of the hinge reinforcement plate 300 overlaps the first overlap surface 211, the above-mentioned step structure can limit the hinge reinforcement plate 300 from moving upward, thereby improving the structural stability of the hinge reinforcement plate 300. When the upper end of the lock installation plate 400 overlaps the first overlap surface 211, the above-mentioned step structure can limit the lock installation plate 400 from moving upward, thereby improving the structural stability of the lock installation plate 400.

[0037] Preferably, since the door inner panel 100 is made of carbon fiber material, the door inner panel 100 can be easily manufactured into a structure of unequal thickness, that is, the door inner panel 100 has a local thickening area, and the local thickening area is located in the circumference of the window structure 110, so as to improve the structural strength of the window structure 110 in the circumference, so the upper window frame reinforcement plate can be eliminated, the investment in component molds can be reduced, the manufacturing cost can be reduced, and the overall deadweight can be reduced. In addition, in order to meet the wiring requirements and the connection requirements of interior-related components, a number of process holes will be opened on the door inner panel 100. Similarly, a local thickening area can be set on the periphery of the process hole with a larger aperture to increase the structural strength of the process hole and reduce its tendency to deform.

[0038] See also Figure 1 , Figure 3 and Figure 4 The front side of the upper window frame 200 has a first reinforcing flange 230 extending forward, and the first reinforcing flange 230 is overlapped with the inner side of the front end of the window structure 110. The rear side of the upper window frame 200 has a second reinforcing flange 240 extending backward, and the second reinforcing flange 240 is overlapped with the inner side of the rear end of the window structure 110.

[0039] The first reinforcing flange 230 has a cavity inside, which is interconnected with the hollow chamber of the upper window frame 200. The first reinforcing flange 230 is integrally formed on the front side of the upper window frame 200 and overlapped with the inner side of the front end of the window structure 110, which can increase the contact area between the upper window frame 200 and the front side of the window structure 110, and improve the structural strength of the upper window frame 200 and the front side of the window structure 110. At the same time, the second reinforcing flange 240 has a cavity inside, which is interconnected with the hollow chamber of the upper window frame 200. The second reinforcing flange 240 is integrally formed on the rear side of the upper window frame 200 and overlapped with the inner side of the rear end of the window structure 110, which can increase the contact area between the upper window frame 200 and the rear side of the window structure 110, and improve the structural strength of the upper window frame 200 and the rear side of the window structure 110, thereby improving the structural strength of the upper window frame 200 and the window structure 110 as a whole.

[0040] Specifically, the thickness of the door inner panel 100 is 1.72 mm to 3.0 mm, the wall thickness of the upper window frame 200 is 1.72 mm, the thickness of the hinge reinforcement plate 300 and the reinforcement plate is 1.5 mm to 2.5 mm, and the preferred thickness of the hinge reinforcement plate 300 and the reinforcement plate is 2.0 mm.

[0041] See also Figure 1The inner side of the door inner panel 100 is also provided with a glass guide rail 500, which is longitudinally arranged at the front lower part of the door inner panel 100. The glass guide rail 500 can provide a guide track for the glass window to rise or fall, and guide the smooth movement of the window glass during the opening and closing process. Among them, the glass guide rail 500 is made of aluminum alloy material, which can further reduce the weight of the door inner panel sub-assembly compared with the glass guide rail 500 made of steel plate in the prior art.

[0042] Specifically, the lower end of the glass guide rail 500 is provided with a mounting bracket 510, which is a Z-shaped structure. The mounting bracket 510 of the Z-shaped structure has two mounting surfaces, which are bolted or riveted to the glass guide rail 500 and the door inner panel 100, respectively, so that the lower end of the glass guide rail 500 forms a stable mounting structure. The lower part of the front end of the inner side surface of the upper window frame 200 also has an assembly surface, which is located above the first overlap surface 211. The upper end of the glass guide rail 500 overlaps the assembly surface and is fixed by bonding, riveting or bolting, so that the upper end of the glass guide rail 500 forms a stable mounting structure.

[0043] Based on the same invention, the utility model also provides a vehicle, which uses the above-mentioned composite material door inner panel subassembly, has an overall lighter weight, can effectively reduce the vehicle's curb weight, and can significantly improve the fuel efficiency of the vehicle using the above-mentioned composite material door inner panel subassembly.
