In this way, Figure 2 As can be seen from the figure, the first reinforcing plate 31 and the second reinforcing plate 32 are generally arranged along the X-axis direction, and the third reinforcing plate 33 is generally arranged along the Z-axis direction. Figure 3 As shown in the figure, the structure formed by the first reinforcing plate 31, the second reinforcing plate 32 and the third reinforcing plate 33 is similar to an H shape (the specific connection position of the first reinforcing plate 31 and the door inner panel 2, and the specific connection position of the second reinforcing plate 32 and the door inner panel 2 should be designed according to needs. For example, the first end of the first reinforcing plate 31 and the first end of the second reinforcing plate 32 can also be connected to the same position of the door inner panel 2, then the structure formed by the first reinforcing plate 31, the second reinforcing plate 32 and the third reinforcing plate 33 will be similar to an A shape).

[0029] Combination Figure 2 and Figure 4As shown, a window frame hole 01 is opened on the door inner panel 2, and the door window frame 4 is a frame structure with a similar shape to the window frame hole 01, and is arranged around the window frame hole 01. The door window frame 4 is connected to the side of the door inner panel 2 away from the cockpit (i.e., the side along the positive direction of the Y-axis) by connection methods such as structural adhesive bonding. In this embodiment, the door window frame 4 can be made of carbon fiber material, which can meet the requirements of lightweight and strength of the window frame. The rearview mirror mounting plate 5 is connected to the side of the door window frame 4 close to the door hinge (i.e., the side along the positive direction of the X-axis, in this embodiment, the acute angle of the door window frame 4 along the positive direction of the X-axis) by means of connection methods such as structural adhesive bonding, and the first reinforcement plate 31 is connected to the side of the rearview mirror mounting plate 5 facing away from the cabin (i.e., the side along the negative direction of the Y-axis) by riveting and / or gluing, etc., which not only meets the installation strength of the rearview mirror, but also improves the strength of the first reinforcement plate 31. In this embodiment, the rearview mirror mounting plate 5 can be made of 5182 aluminum alloy (it can also be other types of aluminum alloy), which achieves a lightweight design while meeting the strength requirements. Preferably, the thickness at different positions on the door outer panel 1 can be 2.5mm~3mm, the thickness at different positions on the door inner panel 2 can be 1.7mm~3mm, the thickness at different positions on the first reinforcing plate 31 can be 1mm~1.5mm, the thickness at different positions on the second reinforcing plate 32 can be 1mm~1.5mm, the thickness at different positions on the third reinforcing plate 33 can be 1mm~1.5mm, and the thickness at different positions on the door window frame 4 can be 1.5mm~2mm, so as to better meet the design requirements of lightweight doors and better meet the strength requirements of doors.

[0030] Preferably, the door outer panel 1 and the door inner panel 2 are both made of carbon fiber, and the first reinforcing plate 31, the second reinforcing plate 32, and the third reinforcing plate 33 are all made of 5182 aluminum alloy (or other types of aluminum alloy). By selecting carbon fiber and aluminum alloy materials, the weight of the corresponding position of the door structure can be reduced while meeting the strength requirements of the corresponding position.

[0031] The vehicle door structure of the present invention has the function of strengthening and rebaring the upper and lower parts of the vehicle door structure respectively through the first reinforcing plate 31 and the second reinforcing plate 32. At the same time, the third reinforcing plate 33 is connected between the first reinforcing plate 31 and the second reinforcing plate 32, so that the first reinforcing plate 31, the second reinforcing plate 32 and the third reinforcing plate 33 form an H-shaped or A-shaped structure, which further improves the strengthening and rebaring effect and plays a stronger supporting role for the vehicle door outer panel 1. At the same time, the first reinforcing plate 31 is connected to the rearview mirror mounting plate 5, and the rearview mirror mounting plate 5 is connected to the vehicle door window frame 4, which improves the installation strength of the rearview mirror and the vehicle door strength near the window frame hole 01. The vehicle door window frame 4 and the rearview mirror mounting plate 5 also play a certain supporting and reinforcing role for the first reinforcing plate 31, so that the first reinforcing plate 31 plays a further supporting role for the vehicle door outer panel 1. The vehicle door structure of the present invention can be suitable for lightweight design. After the material of the corresponding structure is replaced with a lightweight material, the strength of the vehicle door structure can still be kept in compliance with the requirements through the design of the reinforcing plate 3, which effectively improves the safety performance of the vehicle.

[0032] Preferably, the vehicle door outer panel 1 includes a first plate 11 and a second plate 12, the first plate 11 is connected to the top of the second plate 12, a first angle is formed between the first plate 11 and the second plate 12, and the vehicle door inner panel 2 is arranged in accordance with the shape of the first plate 11 and the second plate 12.

[0033] Combination Figure 4 As shown, the first plate 11 and the second plate 12 are integrally connected to form the door outer panel 1. The first plate 11 and the second plate 12 can be bent or straightened as required. In this embodiment, the first plate 11 and the second plate 12 are curved panels obtained by bending. The first angle between the first plate 11 and the second plate 12 refers to the angle between the tangent at any position on the first plate 11 and the tangent at any position on the second plate 12. Therefore, the first angles of the tangents at different positions may be unequal. The door inner panel 2 is arranged in accordance with the first plate 11 and the second plate 12. Preferably, the first angle is 135° to 155°.

[0034] In this way, through the first angle design of the door outer panel 1 and the conformal design of the door inner panel 2, the fitting area between the door outer panel 1 and the door inner panel 2 is increased, thereby improving the connection strength between the door outer panel 1 and the door inner panel 2.

[0035] Furthermore, the side of the first reinforcing plate 31 facing away from the cabin is glued to the side of the door outer panel 1 close to the cabin; the side of the second reinforcing plate 32 facing away from the cabin is glued to the side of the door outer panel 1 close to the cabin; the side of the third reinforcing plate 33 facing away from the cabin is glued to the side of the door outer panel 1 close to the cabin.

[0036] Combination Figure 2 and Figure 4 As shown, the first reinforcing plate 31 is coated with structural adhesive on the side away from the cabin (i.e., the side along the positive direction of the Y axis), the second reinforcing plate 32 is coated with structural adhesive on the side away from the cabin (i.e., the side along the positive direction of the Y axis), and the third reinforcing plate 33 is coated with structural adhesive on the side away from the cabin (i.e., the side along the positive direction of the Y axis). The structural adhesive on the first reinforcing plate 31 is mainly arranged on the edge of the first reinforcing plate 31, so as to be bonded with the side of the door outer panel 1 away from the cabin (i.e., the side opposite to the Y axis); the structural adhesive on the second reinforcing plate 32 is arranged at intervals along the extension direction of the second reinforcing plate 32, and can be designed according to the actual size of the second reinforcing plate 32, so as to be bonded with the side of the door outer panel 1 away from the cabin (i.e., the side opposite to the Y axis); the structural adhesive on the third reinforcing plate 33 can refer to the first reinforcing plate 31 and the second reinforcing plate 32, or be arranged as needed, so as to be bonded with the side of the door outer panel 1 away from the cabin (i.e., the side opposite to the Y axis).

[0037] In this way, the first reinforcing plate 31 , the second reinforcing plate 32 and the third reinforcing plate 33 are respectively bonded to the door outer panel 1 , thereby better supporting and reinforcing the door outer panel 1 , further improving the safety performance of the vehicle.

[0038] Furthermore, it also includes a door hinge mounting plate 6, and the reinforcement plate 3 also includes a fourth reinforcement plate 34, the fourth reinforcement plate 34 is glued to the side of the door inner panel 2 close to the door hinge, the door hinge mounting plate 6 is connected to the fourth reinforcement plate 34, and the door hinge mounting plate 6, the fourth reinforcement plate 34 and the door inner panel 2 are connected by fasteners. Figure 2 and Figure 4 As shown, the thickness of the fourth reinforcing plate 34 can be 1.3mm~1.8mm, and there are two door hinge mounting plates 6, which are respectively welded (spot welding can be used) and fixed on the upper part and the lower part of the fourth reinforcing plate 34 (that is, the part of the fourth reinforcing plate 34 close to the positive direction of the Z axis and the part close to the reverse direction of the Z axis). The fourth reinforcing plate 34 is bonded to the door inner panel 2 by structural adhesive (the fourth reinforcing plate 34 is located in the inner cavity between the door outer panel 1 and the door inner panel 2), and the fourth reinforcing plate 34 is located on the side close to the door hinge (that is, the side of the positive direction of the X axis). Through holes are opened on the door hinge mounting plate 6, the fourth reinforcing plate 34 and the door inner panel 2 to allow fasteners to pass through and connect and fix the three. In this embodiment, the fourth reinforcing plate 34 can be made of 590DP dual-phase steel (other types of steel can also be used). The door hinge mounting plate 6 is used to be connected to the door hinge, so as to connect the door structure with the body and realize the rotating opening and closing function of the door structure.

[0039] In this way, the strength of the door structure near the door hinge is strengthened by the fourth reinforcing plate 34, which meets the installation strength of the door hinge and can withstand the weight of the door structure and the door opening and closing torque, thereby avoiding the situation where the structural strength near the door hinge does not meet the requirements after the door is lightweight designed.

[0040] Furthermore, the reinforcing plate 3 further includes a fifth reinforcing plate 35 , and the fifth reinforcing plate 35 is glued to a side of the door inner panel 2 close to the door lock.

[0041] Combination Figure 2 and Figure 4 As shown, the thickness of the fifth reinforcing plate 35 can be 1.7mm~2.2mm. The fifth reinforcing plate 35 is located in the inner cavity between the door outer panel 1 and the door inner panel 2. The fifth reinforcing plate 35 is glued to the side of the door inner panel 2 close to the door lock (i.e., the side opposite to the X-axis in the figure). The door lock is arranged at the position corresponding to the fifth reinforcing plate 35. In this embodiment, the fifth reinforcing plate 35 is made of 5182 aluminum alloy (it can also be other types of aluminum alloy). The fifth reinforcing plate 35 is used to meet the installation strength of the door lock. At the same time, the use of aluminum alloy can reduce the weight of components.

[0042] Furthermore, the first end of the second reinforcing plate 32 is connected to the door inner panel 2 through the fourth reinforcing plate 34 , and the second end of the second reinforcing plate 32 is connected to the door inner panel 2 through the fifth reinforcing plate 35 .

[0043] Combination Figure 2 , Figure 3 and Figure 4 As shown, the first end of the second reinforcing plate 32 (i.e., the end along the positive direction of the X-axis) is bonded to the fourth reinforcing plate 34 by structural adhesive, and the second end of the second reinforcing plate 32 (i.e., the end along the reverse direction of the X-axis) and the fifth reinforcing plate 35 are both provided with through holes. After the rivet passes through the through hole, the second end of the second reinforcing plate 32 and the fifth reinforcing plate 35 are riveted and fixed, which effectively improves the tensile strength and shear strength of the connection between the second reinforcing plate 32 and the fifth reinforcing plate 35. With the help of the strength of the fourth reinforcing plate 34 and the fifth reinforcing plate 35, the second reinforcing plate 32 has a better supporting and reinforcing effect on the door outer panel 1.

[0044] Furthermore, the first end of the first reinforcing plate 31 is connected to the door window frame 4 near the door hinge through the rearview mirror mounting plate 5, and the second end of the first reinforcing plate 31 is connected to the door window frame 4 near the door lock.

[0045] Combination Figure 2 and Figure 4As shown, the first end of the first reinforcing plate 31 (i.e., the end along the positive direction of the X-axis) is glued and riveted to the rearview mirror mounting plate 5, and the rearview mirror mounting plate 5 is connected to the door window frame 4 on the side close to the door hinge (in this embodiment, along the opposite side of the Z-axis and biased to the positive direction of the X-axis, i.e. Figure 2 The first reinforcing plate 31 is glued to the lower left corner of the vehicle door window frame 4, and the second end (i.e., the end in the opposite direction along the X axis) of the first reinforcing plate 31 is glued to the side of the vehicle door window frame 4 close to the vehicle door lock (in this embodiment, in the opposite direction along the Z axis and biased to the opposite side of the X axis, i.e. Figure 2 The lower right corner of the middle door window frame 4).

[0046] In this way, the first reinforcing plate 31 plays a better role in reinforcing the area near the window frame hole 01 and the rearview mirror. At the same time, the door window frame 4 and the rearview mirror mounting plate 5 also provide mounting points for the first reinforcing plate 31 to ensure the reinforcing effect of the first reinforcing plate 31.

[0047] Furthermore, it also includes an anti-collision beam 7 located below the reinforcing plate 3, the anti-collision beam 7 includes a first connecting member 71, a second connecting member 72 and an anti-collision beam body 73, the first end of the anti-collision beam body 73 is connected to the side of the door inner panel 2 close to the door hinge through the first connecting member 71, and the second end of the anti-collision beam body 73 is connected to the side of the door inner panel 2 close to the door lock through the second connecting member 72.

[0048] Combination Figure 2 and Figure 4 As shown, the anti-collision beam body 73 in this embodiment is in the shape of a circular tube (the wall thickness of which can be 2mm~2.5mm), and is made of hot-formed steel. The first connecting member 71 and the second connecting member 72 are made of sheet metal. The first connecting member 71 and the second connecting member 72 are respectively welded (carbon dioxide gas shielded welding can be used) to the first end and the second end of the anti-collision beam body 73. The first connecting member 71 is bonded to the fourth reinforcement plate 34 by structural adhesive, and is also fixed to the door inner panel 2 near the door hinge side by bolts. The second connecting member 72 is glued and fixed to the door inner panel 2 near the door lock side.

[0049] In this way, the anti-collision beam 7 can improve the anti-collision performance of the door structure to meet the vehicle safety collision requirements, and the two ends of the anti-collision beam body 73 are fixed to the door inner panel 2 through the first connecting member 71 and the second connecting member 72, thereby improving the installation strength of the anti-collision beam 7 and thus improving the safety performance of the vehicle.

[0050] Furthermore, the side of the anti-collision beam 7 facing away from the cockpit is glued to the side of the door outer panel 1 close to the cockpit.

[0051] Combination Figure 2 and Figure 4As shown, exemplarily, structural adhesive is coated at intervals along its extension direction on the side of the anti-collision beam body 73 facing away from the cabin (i.e., the side along the positive direction of the Y axis), so as to be glued and fixed to the side of the door outer panel 1 close to the cabin (i.e., the side along the opposite direction of the Y axis).

[0052] In this way, the anti-collision beam 7 supports and reinforces the door outer panel 1, thereby improving the anti-collision performance of the door structure. After the door structure adopts a lightweight design, the safety performance of the vehicle can still be guaranteed to meet the requirements.

[0053] Preferably, a third connecting member 8 is further included, and the side of the anti-collision beam 7 facing away from the cockpit is connected to the third connecting member 8, and the third connecting member 8 is glued to the side of the vehicle door outer panel 1 close to the cockpit.
