[0040] With the popularization of vehicles, people now pay more and more attention to the safety performance of vehicles. Doors are an important part of vehicles. Doors can not only isolate interference from outside the vehicle, but also reduce side impacts and protect passengers.

[0041] Specifically, the vehicle body is provided with passenger entrances, for example, a left front entrance (driver entrance), a right front entrance (co-pilot entrance), a left rear entrance, and a right rear entrance. The vehicle doors are rotatably connected to the passenger entrances of the vehicle body. The vehicle doors have an open state and a closed state. When the vehicle doors are in an open state, the interior of the vehicle is connected with the exterior of the vehicle through the passenger entrances. When the vehicle doors are in a closed state, the interior of the vehicle is isolated from the exterior of the vehicle.

[0042] The vehicle door may include a door outer panel, a door inner panel and a door inner panel assembly 100, which are stacked in sequence, with the door outer panel facing the outside of the vehicle and the door inner panel facing the inside of the vehicle, and the door inner panel assembly 100 located between the door inner panel and the door outer panel.

[0043] In the prior art, when a vehicle door structure is hit from the side, the door is prone to significant deformation, causing the door lock to be damaged, increasing the risk of the door being unable to open in a collision.

[0044] To solve the above technical problems, please refer to Figure 1 and Figure 2 The present application provides a vehicle door inner panel assembly 100 , which includes a vehicle door inner panel 110 and a lower reinforcement panel 120 .

[0045] Specifically, the door inner panel 110 may include a first surface 113 facing the interior of the vehicle, and the door inner panel 110 may include an installation opening 112 and a window opening 111 , wherein the window is installed at the window opening 111 , and the installation opening 112 is used to install a window control device and for wiring.

[0046] The lower reinforcing plate 120 is located at a side of the installation opening 112 away from the vehicle window 111 . The lower reinforcing plate 120 is disposed on the first surface 113 of the door inner panel 110 . The lower reinforcing plate 120 extends along a first direction.

[0047] It can be understood that the X-axis direction of the vehicle coordinate system refers to the front-rear direction of the vehicle, the Y-axis direction of the vehicle coordinate system refers to the left-right direction of the vehicle, and the Z-axis direction of the vehicle coordinate system refers to the up-down direction of the vehicle. The first direction refers to the X-axis direction of the vehicle coordinate system (for example, Figure 1 anteroposterior direction as shown in ).

[0048] Therefore, by setting the lower reinforcement plate 120, the thickness of the side of the door inner panel assembly 100 can be increased, thereby increasing the lateral strength of the door inner panel assembly 100, thereby enhancing the lateral collision resistance of the door, reducing the risk of the door being unable to open during a side collision of the vehicle, and improving the safety of passengers inside the vehicle.

[0049] Among them, it can be understood that the lower reinforcement plate 120 is fixedly connected to the door inner panel 110. Specifically, a first threaded hole 122 is provided on the lower reinforcement plate 120, and a second threaded hole is provided on the door inner panel 110. The first threaded hole 122 and the second threaded hole are penetrated by bolts to realize the fixed connection between the lower reinforcement plate 120 and the door inner panel 110.

[0050] In some other embodiments of the present application, the lower reinforcement plate 120 can be fixedly connected to the door inner panel 110 by welding; or can be fixedly connected by gluing.

[0051] In some embodiments of this application, please continue to refer to Figure 1 The lower reinforcing plate 120 is provided with a reinforcing protrusion 121, which protrudes from the side surface of the lower reinforcing plate 120 away from the door inner panel 110 toward the direction away from the door inner panel 110. In this way, by providing the reinforcing protrusion 121, the thickness of the door inner panel assembly 100 at the side can be further increased, and the lateral strength of the door inner panel assembly 100 can be further enhanced, thereby enhancing the lateral anti-collision capability of the door, reducing the risk of the door being unable to open during a side collision of the vehicle, and improving the safety of passengers inside the vehicle.

[0052] Among them, the reinforcing protrusion 121 can also provide buffering and energy absorption during a side collision, further enhancing the lateral collision resistance of the door.

[0053] In a specific implementation process, there are multiple reinforcing protrusions 121 , and the multiple reinforcing protrusions 121 are arranged at intervals on the lower reinforcing plate 120 .

[0054] In some embodiments of the present application, the lower reinforcing plate 120 is Figure 1 The length of the door inner panel 110 in the front-to-rear direction shown in is a first length, the length of the door inner panel 110 in the extending direction of the lower reinforcing plate 120 is a second length, and the first length is greater than or equal to 1 / 2 of the second length.

[0055] In a specific implementation process, the first length can be 1 / 2, 2 / 3, 3 / 4, 4 / 5, etc. of the second length.

[0056] For example, the second length is 900 mm and the first length is 450 mm.

[0057] In some other embodiments of the present application, the first length may be equal to the second length, so that the length of the lower reinforcing plate 120 is the longest, and the lateral strength of the door inner panel assembly 100 can be enhanced to the greatest extent. It can be understood that the lengthening of the lower reinforcing plate 120 can increase the force-bearing area of ​​the lower reinforcing plate 120, increase the high-strength area of ​​the door inner panel assembly 100, and thus increase the lateral strength of the door inner panel assembly 100.

[0058] In some embodiments of the present application, please refer to Figure 1 The door inner panel assembly 100 may further include an upper reinforcement plate 130, which is located on the side of the mounting opening 112 close to the window 111. Thus, by providing the upper reinforcement plate 130, the strength of the upper portion of the door inner panel assembly 100 is increased, thereby increasing the lateral strength of the door and improving the lateral anti-collision capability of the door.

[0059] In some embodiments of this application, please refer to Figure 1 and Figure 3 The door inner panel assembly 100 may further include an anti-collision beam 140, which is disposed on the door inner panel 110 and between the upper reinforcement plate 130 and the lower reinforcement plate 120. Thus, by arranging the anti-collision beam 140, the strength of the middle portion of the door inner panel assembly 100 may be enhanced, thereby increasing the lateral strength of the door and improving the lateral anti-collision capability of the door.

[0060] In some embodiments of this application, please refer to Figure 3 The anti-collision beam 140 is provided with a first reinforcing rib 141 and a second reinforcing rib 142. The extension direction of the first reinforcing rib 141 is the same as the extension direction of the anti-collision beam 140. The extension direction of the second reinforcing rib 142 is the same as the extension direction of the anti-collision beam 140. The first reinforcing rib 141 and the second reinforcing rib 142 are arranged at intervals in the second direction; wherein the second direction is perpendicular to the extension direction of the anti-collision beam 140.

[0061] That is to say, the cross-sectional shape of the anti-collision beam 140 is "M"-shaped, which can ensure the strength requirement of the anti-collision beam 140 while saving the raw materials of the anti-collision beam 140 and reducing the weight, and further enhance the anti-collision ability of the side of the vehicle door.

[0062] Specifically, the heights of the first reinforcing rib 141 and the second reinforcing rib 142 of the anti-collision beam 140 are both greater than or equal to 40 mm. In this way, if the door space permits, the lateral size of the anti-collision beam 140 can be increased, thereby further increasing the anti-collision capability of the door side.

[0063] In some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The anti-collision beam 140 may include a first end 143 and a second end 144, the first end 143 and the second end 144 are opposite to each other in the extension direction of the anti-collision beam 140, and the first end 143 extends to the edge of the door inner panel 110. Thus, the length of the anti-collision beam 140 is increased, the overall strength of the door is increased, and the anti-side collision capability of the door is increased.

[0064] In some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The second end 144 also extends to the edge of the door inner panel 110, thereby maximizing the length of the anti-collision beam 140, increasing the overall strength of the door, and increasing the anti-side collision capability of the door.

[0065] In some embodiments of this application, please continue to refer to Figure 1 The door inner panel assembly 100 may further include a middle reinforcement plate 150, one end of which is connected to the upper reinforcement plate 130, and the other end of which is connected to the anti-collision beam 140. By providing the middle reinforcement plate 150 to connect the upper reinforcement plate 130 with the anti-collision beam 140, the integrity of the door inner panel assembly 100 is improved. At the same time, the strength of the middle part of the door is increased, thereby increasing the side impact resistance of the door.

[0066] In some embodiments of this application, please continue to refer to Figure 1 The door inner panel assembly 100 may further include a hinge reinforcement plate 160, which is located at the connection between the door and the vehicle body, and is used to enhance the stability of the connection between the door and the vehicle body and reduce the stability of the connection between the door and the vehicle body when the vehicle collides from the side.

[0067] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
