[0029] Please refer to Figures 1 to 8 , and now the door inner panel connection structure and the vehicle provided by the present utility model will be described. The door inner panel connection structure includes a door inner panel 1, a window frame reinforcement plate 2, a door lock reinforcement plate 3, and a hinge reinforcement plate 4. The window frame reinforcement plate 2 is a hollow tubular structure. The window frame reinforcement plate 2 is connected to the side of the door inner panel 1 away from the central axis of the vehicle body. Both the hinge reinforcement plate 4 and the door lock reinforcement plate 3 are connected to the side of the door inner panel 1 away from the central axis of the vehicle body and extend upward to be connected to the outer side wall of the window frame reinforcement plate 2. The hinge reinforcement plate 4 is arranged near the front edge of the door inner panel 1, and the door lock reinforcement plate 3 is arranged near the rear edge of the door inner panel 1.

[0030] Compared with the prior art, for the door inner panel connection structure provided in this embodiment, the window frame reinforcement plate 2 of the door inner panel connection structure provided in this embodiment adopts a hollow tubular structure. The door inner panel 1 is connected to one side of the window frame reinforcement plate 2, and both the hinge reinforcement plate 4 and the door lock reinforcement plate 3 are connected to the other side of the window frame reinforcement plate 2, which is convenient for forming a Y-direction support moment, helps to increase the overall stiffness of the door. At the same time, the window frame reinforcement plate 2 is connected to the hinge reinforcement plate 4 and the door lock reinforcement plate 3, and a force transmission channel from top to bottom can be formed, enhancing the force transmission continuity at the door position and ensuring the overall structural performance of the door.

[0031] In this embodiment, the window frame reinforcing plate 2 adopts a hollow tubular structure. One side is connected to the inner door panel 1, and the other side is connected to the hinge reinforcing plate 4 and the door lock reinforcing plate 3. The lower parts of the hinge reinforcing plate 4 and the door lock reinforcing plate 3 are connected to the inner door panel 1, and the upper parts are connected to the side wall of the window frame reinforcing plate 2, which can form a Y-direction support moment and form a reliable support structure, helping to improve the overall stiffness of the door. The above stiffness refers to parameters such as sag stiffness and extrusion stiffness.

[0032] Specifically, the window frame reinforcing plate 2 can be set as a tubular member extending along the lower edge of the window, or it can be an annular tubular member surrounding the outer periphery of the window. If the window frame reinforcing plate 2 is a tubular member extending along the lower edge of the window, the front and rear ends of the window frame reinforcing plate 2 are respectively connected to the hinge reinforcing plate 4 and the door lock reinforcing plate 3; if the window frame reinforcing plate 2 is an annular tubular member surrounding the outer periphery of the window, the areas near the front and rear sides of the lower part of the window frame reinforcing plate 2 are respectively connected to the hinge reinforcing plate 4 and the door lock reinforcing plate 3, both of which can achieve good structural strengthening effects.

[0033] In order to achieve lightweight design of the structure, the inner door panel 1 and the window frame reinforcing plate 2 can be made of carbon fiber material. The hinge reinforcing plate 4, the door lock reinforcing plate 3, the inner door panel 1 and the window frame reinforcing plate 2 can be bonded by structural adhesive, which has the characteristics of high strength and light weight, improving the overall performance of the vehicle.

[0034] In some possible implementation manners, the above-mentioned window frame reinforcing plate 2 adopts structures such as Figure 1 and Figure 3 as shown. Referring to Figure 1 and Figure 3 , the front part of the window frame reinforcing plate 2 has a front connecting portion 21 extending downward. The inside of the front connecting portion 21 is communicated with the inside of the window frame reinforcing plate 2. One side wall of the front connecting portion 21 is connected to the inner door panel 1, and the other side wall of the front connecting portion 21 is connected to the hinge reinforcing plate 4.

[0035] In this embodiment, in order to facilitate the connection between the window frame reinforcing plate 2 and the hinge reinforcing plate 4, a front connecting portion 21 is provided below the front part of the window frame reinforcing plate 2. The inner cavity of the front connecting portion 21 is also communicated with the inner cavity of the window frame reinforcing plate 2. The front connecting portion 21, the rear connecting portion 22 and the window frame reinforcing plate 2 are integrally formed.

[0036] Similarly, the rear part of the window frame reinforcing plate 2 has a rear connecting portion 22 extending downward. The rear connecting portion 22 connected to the window frame reinforcing plate 2 is also a hollow member. The inside of the rear connecting portion 22 is communicated with the inside of the window frame reinforcing plate 2. One side wall of the rear connecting portion 22 is connected to the inner door panel 1, and the other side wall of the rear connecting portion 22 is connected to the door lock reinforcing plate 3.

[0037] Specifically, the thickness of the rear connecting portion 22 in the left - right direction is less than the thickness of the window frame reinforcing plate 2 in the left - right direction. The side wall of the rear connecting portion 22 adjacent to the door lock reinforcing plate 3 is recessed inward relative to the window frame reinforcing plate 2, which facilitates the connection with the door lock reinforcing plate 3, provides sufficient clearance space, and is convenient for structural layout.

[0038] In some embodiments, the above - mentioned rear connecting portion 22 may adopt a structure as Figure 3 shown. Refer to Figure 3 , the side wall of the front connecting portion 21 away from the door inner panel 1 inclines downward from top to bottom towards the side close to the door inner panel 1, and the cross - section of the front connecting portion 21 is triangular; or the side wall of the rear connecting portion 22 away from the door inner panel 1 inclines downward from top to bottom towards the side close to the door inner panel 1, and the cross - section of the rear connecting portion 22 is triangular; or the side walls of the rear connecting portion 22 and the front connecting portion 21 away from the door inner panel 1 incline downward from top to bottom towards the side close to the door inner panel 1, and the cross - sections of both the front connecting portion 21 and the rear connecting portion 22 are triangular.

[0039] In this embodiment, in order to enhance the Y - direction support performance, that is, the support performance in the left - right direction, the structure of the front connecting portion 21 is taken as an example for description. The side wall of the front connecting portion 21 connected to the door inner panel 1 and the corresponding side wall of the window frame reinforcing plate 2 adopt a flush structure, which is convenient for both of them to form a connecting effect with the door inner panel 1 simultaneously.

[0040] The side wall of the front connecting portion 21 away from the door inner panel 1, that is, the side wall connected to the hinge reinforcing plate 4, gradually inclines downward from top to bottom towards the central axis side of the vehicle body, so that the longitudinal cross - section of the front connecting portion 21 forms a cross - section similar to a triangle, and this triangle is an inverted triangle with a larger upper part and a smaller lower part. The stability of the triangle is used to further improve the overall structural stiffness of the door. Similarly, the rear connecting portion 22 can also adopt the same structure, which can improve the overall performance of the door.

[0041] In some embodiments, the above - mentioned hinge reinforcing plate 4 may adopt a structure as Figure 1 and Figure 4 shown. Refer to Figure 1 and Figure 4 , the upper part of the hinge reinforcing plate 4 is provided with a connecting plate 41 extending backward, and the connecting plate 41 is connected to the side wall of the front connecting portion 21. The setting of the connecting plate 41 facilitates the connection between the hinge reinforcing plate 4 and the front connecting portion 21. The connecting plate 41 extends backward, and the side wall of the connecting plate 41 can be attached and bonded to the outer side wall of the front connecting portion 21, which is convenient for increasing the connection area with the front connecting portion 21 and ensuring the reliability of the connection.

[0042] In some possible implementation manners, the above - mentioned front connecting portion 21 adopts a structure as Figure 3 shown. Refer to Figure 3, the height of the front connecting portion 21 gradually increases from the rear to the front in the vertical direction, and the height of the rear connecting portion 22 gradually increases from the front to the rear in the vertical direction.

[0043] In this embodiment, the result is described by taking the rear connecting portion 22 as an example. The height of the rear connecting portion 22 gradually increases from the front to the rear, so that the portion of the rear connecting portion 22 adjacent to the door lock reinforcement plate 3 has a larger area, which helps to increase the connection area with the door lock reinforcement plate 3 and ensure the reliability of the connection. Similarly, the front connecting portion 21 can also be reliably connected to the connecting plate 41, improving the convenience.

[0044] In some embodiments, the above-mentioned feature, the front connecting portion 21 can adopt a structure as Figure 3 shown. Refer to Figure 3 , the outer side wall of the front connecting portion 21 is concave inward toward the vehicle body central axis side, and the hinge reinforcement plate 4 is connected to the outer side wall of the front connecting portion 21. The side wall of the front connecting portion 21 relative to the window frame reinforcement plate 2 is concave inward toward the vehicle body inner side, providing sufficient installation space for the connecting plate 41 behind the hinge reinforcement plate 4, avoiding the problem of forming an outward protrusion due to their stacked arrangement, and realizing the reasonable layout of the space.

[0045] In some embodiments, the above-mentioned feature, the window frame reinforcement plate 2 can adopt a structure as Figure 1 and Figure 5 shown. Refer to Figure 1 and Figure 5 , a front extension portion 23 connected to the door inner panel 1 is integrally formed on the front side of the window frame reinforcement plate 2, or a rear extension portion connected to the door inner panel 1 is integrally formed on the rear side of the window frame reinforcement plate 2, or a front extension portion 23 is integrally formed on the front side of the window frame reinforcement plate 2 and a rear extension portion is integrally formed on the rear side at the same time. Both the front extension portion 23 and the rear extension portion are located on the side of the door inner panel 1 away from the vehicle body central axis.

[0046] In this embodiment, the front extension portion 23 provided on the front side of the window frame reinforcement plate 2 is also a hollow structure. The front extension portion 23 is integrally formed with the window frame reinforcement plate 2. The thickness of the front extension portion 23 in the left-right direction is smaller than the thickness of the window frame reinforcement plate 2 in the left-right direction. The front extension portion 23 can be connected to the side wall of the door inner panel 1 away from the vehicle body central axis, effectively increasing the connection area.

[0047] It should be noted that according to the actual structural conditions, it is possible to choose to provide the front extension portion 23 on the front side of the window frame reinforcement plate 2, or provide the rear extension portion on the rear side of the window frame reinforcement plate 2, or provide both the front extension portion 23 on the front side of the window frame reinforcement plate 2 and the rear extension portion on the rear side of the window frame reinforcement plate 2, so as to ensure the connection reliability between the window frame reinforcement plate 2 and the door inner panel 1.

[0048] In some possible implementation manners, the above-mentioned feature, the window frame reinforcement plate 2 adopts a structure as Figure 1 andFigure 3 The structure shown. Refer to Figure 1 and Figure 3 , the window frame reinforcing plate 2 is an annular member surrounding the outer periphery of the window frame. A connecting flange 11 bent outwardly toward the vehicle body is provided on the inner door panel 1, and the connecting flange 11 is connected to the window frame reinforcing plate 2.

[0049] In this embodiment, the window frame reinforcing plate 2 surrounds the outer periphery of the window frame to form a closed annular structure, which can synchronously enhance the structure in the circumferential direction of the window frame. The connecting flange 11 provided on the inner door panel 1 extends outwardly toward the vehicle body and can be connected to the peripheral wall of the window frame reinforcing plate 2, which helps to increase the bonding area and ensure the reliability of the connection.

[0050] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, and the vehicle includes an inner door panel connection structure. The window frame reinforcing plate 2 of the above vehicle adopts a hollow tubular structure, the inner door panel 1 is connected to one side of the window frame reinforcing plate 2, and both the hinge reinforcing plate 4 and the door lock reinforcing plate 3 are connected to the other side of the window frame reinforcing plate 2, which is convenient for forming a Y-direction support moment, helps to increase the overall stiffness of the door, forms a force transmission channel from top to bottom, enhances the force transmission continuity at the door position, and ensures the overall structural performance of the door.

[0051] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
