To facilitate understanding of the vehicle door assembly provided in the embodiment of the present application, its application scenario is first described. The vehicle door assembly provided in the embodiment of the present application can be applied to vehicles, and in particular to vehicle doors. In one possible implementation, in order to increase the area of the vehicle door side windows, the triangular area between the vehicle window and the side pillar may be greatly compressed, resulting in the difficulty in further reducing the size of the triangular block of the vehicle door guard plate, making it difficult to install the triangular block of the vehicle door guard plate in the triangular area between the smaller window and the side pillar of some vehicle models. Based on this, the embodiment of the present application provides a vehicle door assembly to improve the problem that the triangular block is difficult to adapt to the triangular area between the smaller window and the side pillar.

For the convenience of understanding the vehicle door assembly provided by the embodiments of the present application, the following embodiments are all based on the vehicle front door as an example. On the vehicle front door, the triangular area between the window and the side pillar is located in front of the vehicle door along the length direction of the vehicle body.

Refer to Figures 1, 2 and 3 together, Figure 1 is a schematic diagram of the door guard plate triangle block in the embodiment of the present application; Figure 2 is a schematic diagram of the clamping connection between the door guard plate triangle block and the extension part in the embodiment of the present application; Figure 3 is a schematic diagram of the extension part in the embodiment of the present application.

The vehicle door assembly provided in the embodiment of the present application includes a vehicle door panel body 1 and a vehicle door panel triangle block 2. The vehicle door panel body 1 refers to the panel portion covering the entire portion below the vehicle window on the inner side of the vehicle door. The vehicle door panel triangle block 2 is located above the vehicle door panel body 1 along the vehicle body height direction, and can be arranged side by side with the vehicle door panel body 1, and the vehicle door panel triangle block 2 is filled in the triangular area between the vehicle window and the side pillar.

In the embodiment of the present application, the door guard panel body 1 and the door guard panel triangle block 2 are integrally formed. The specific molding method may be that the door guard panel body 1 and the door guard panel triangle block 2 are jointly molded and injection molded, etc. Of course, the door guard panel body 1 and the door guard panel triangle block 2 provided in the embodiment of the present application may be injection molded of the same material, or may be made of different materials using a two-color injection molding process.

The door assembly provided in the example of the present application also includes a door sheet metal 3, which is stacked with the door panel body 1 to form a door structure. The door sheet metal 3 has an extension portion 31. As an example, the specific form of the extension portion 31 may be a shape similar to the door panel triangle block 2 as shown in FIG3, but slightly smaller than the door panel triangle block 2. Usually, a small piece of triangular glass is provided on the side of the extension portion 31 away from the door panel triangle block 2, and the triangular glass and the door panel triangle block 2 form a triangular space, and the extension portion 31 is located inside the triangular space. The extension portion 31, which is similar in shape to the door panel triangle block 2, can obtain the largest possible area without being exposed in the triangular space, so as to leave enough space to fix components such as rearview mirrors.

In the vehicle body height direction, the extension part 31 extends at least to the first height of the door panel triangular block 2. The door panel triangular block 2 is fixedly connected with the extension part 31 by clamping. Specifically, the door panel triangular block 2 is connected with the extension part 31 in the vehicle body height direction, and the position where the door panel triangular block 2 is fixedly connected with the extension part 31 is not lower than the second height of the door panel triangular block 2. By setting the clamping fixation of the triangular block 2 and the extension part 31, the displacement of the door panel triangular block 2 in the vehicle body width direction and the vehicle body length direction can be limited. In addition, the clamping form is adopted, and the assembly process is relatively simple, and it is convenient to disassemble for maintenance.

The door panel triangle block 2 is fixedly connected to the extension portion 31 at a second height higher than the door panel triangle block 2, which can effectively reduce the position deviation of the upper end of the door panel triangle block 2 along the vehicle body height direction. The specific fixed connection method between the door panel triangle block 2 and the extension portion 31 provided in the embodiment of the present application can be clamping, riveting, welding, bonding, etc.

The door panel triangle block 2 is fixedly connected, so that the triangle block 2 and the extension 31 can maintain a fixed distance, so as to control the surface difference between the door panel triangle block 2 as a whole and other decorative panels of the car, such as the side pillar decorative panel, and thus improve the sealing of the door panel. As for the door panel triangle block 2 integrally formed with the door panel body 1, the position of the door panel triangle block 2 can be limited by the integrally formed connection mode at the lower side of the vehicle body height direction, that is, close to the side of the door panel body 1. Therefore, the fixing point of the door panel triangle block 2 and the extension 31 is set at or above the second height of the door panel triangle block 2 along the vehicle body height direction, so as to better limit the position of the door panel triangle block 2 away from the side area of the door panel body 1.

For the triangular block 2, its lower end along the vehicle body height direction is integrally formed with the door panel body 1, so the door panel body 1 can limit the position of the lower end of the door panel triangular block 2, while the position of the upper end of the door panel triangular block 2 is maintained, which requires the door panel triangular block 2 to be further fixedly connected with the extension 31. Therefore, the position at the second height should be able to limit the displacement of the door panel triangular block 2 as a whole, especially the part above the connection, along the vehicle body width direction when the extension 31 is fixedly connected with the door panel triangular block 2. Among them, the specific determination of the second height is closely related to the structural strength of the door panel triangular block 2 itself and the size of the door panel triangular block 2, so for the door panel triangular block 2 used in different vehicle models, the absolute value of the second height may also be different.

In order to achieve a fixed connection between the door panel triangle block 2 and the extension portion 31 , the height of the first height at which the extension portion 31 extends should be greater than or equal to the height of the second height at which the extension portion 31 is connected to the door panel triangle block 2 .

As an optional embodiment, the first height of the door panel triangle block 2 and the second height of the door panel triangle block 2 are both at 1/2 of the height of the door panel triangle block 2 along the height direction of the vehicle body. That is, when applied to a specific vehicle model, along the height direction of the vehicle body, the position where the door panel triangle block 2 is fixedly connected to the extension portion 31 is at 1/2 or more of the height of the door panel triangle block 2, and in order to meet the demand for fixed connection, the extension portion 31 also extends to 1/2 or more of the height of the door panel triangle block 2. By setting the position where the door panel triangle block 2 is fixedly connected to the extension portion 31 at 1/2 or more of the height of the door panel triangle block 2, the demand for limiting the movement of the door panel triangle block 2 along the width direction of the vehicle body can be met. Of course, in some other possible embodiments, due to the different sizes of the door panel triangle block 2 and the structural strength of the door panel triangle block 2 itself, the first height and the second height of the embodiment of the present application can also be other values, which will not be repeated here.

Compared with the traditional door panel triangle block 2, the door panel triangle block 2 provided in the embodiment of the present application is integrally formed with the door panel body 1, and the lower end of the door panel triangle block 2 is integrally connected to the door panel body 1, forming a reliable connection between the door panel triangle block 2 and the door panel body 1, and at the same time, the relative upper end of the door panel triangle block 2 is clamped and fixed to the extension part 31 of the door sheet metal 3, so that the door panel triangle block 2 is firmly fixed as a whole, and there is no need to additionally set up a connecting structure between the door panel triangle block 2 and the door panel body 1. Therefore, when designing the door panel triangle block 2, it is only necessary to consider reserving space for connecting other structures such as rearview mirrors, and there is no need to reserve space for additional connecting structures, so that the size of the door panel triangle block 2 can be reduced to match the triangular area between the smaller size of the window glass and the side pillar.

As an optional embodiment, a triangular block reinforcement rib 21 is provided on the door panel triangular block 2. Specifically, the triangular block reinforcement rib 21 is located on the side of the door panel triangular block 2 facing the extension portion. As an example, two parallel triangular block reinforcement ribs 21 are provided on the side of the door panel triangular block 2 facing the extension portion 31 as shown in FIG1 . The triangular block reinforcement rib 21 can effectively strengthen the overall structural rigidity of the door panel triangular block 2, making the door panel triangular block 2 less likely to dent. At the same time, the door panel triangular block 2 with a stronger anti-deformation ability of the triangular block reinforcement rib 21 is also conducive to better maintaining the gap between the door panel triangular block 2 and other trim panels, and improving the sealing of the triangular area between the window and the side pillar.

Of course, the specific form of the triangular block reinforcement ribs 21 is not limited to the one shown in FIG. 1 . In other possible implementations, the number of the triangular block reinforcement ribs 21 may be 3, 4, 5, etc. These triangular block reinforcement ribs 21 may be arranged in parallel or crosswise, or some of the triangular block reinforcement ribs 21 may be arranged in parallel and some of the triangular block reinforcement ribs 21 may be crosswise, etc.

The specific form of the clamping and fixing of the door guard plate triangle block 2 and the extension portion 31 will be described in detail below with reference to the accompanying drawings.

As an optional embodiment, when the door panel triangle block 2 and the extension portion 31 are connected, the door panel triangle block 2 is provided with a clamping plate 22 toward the extension portion 31. The clamping plate 22 can be perpendicular to the height direction of the vehicle body or at a certain angle to the height direction of the vehicle body. As an example, the clamping plate 22 shown in FIG. 1 is arranged perpendicular to the height direction of the vehicle body. The clamping plate 22 can be integrally formed with the door panel triangle block 2, or can be fixedly connected to the door panel triangle block 2 by welding, bonding, etc.

A clamping hole (not marked in the figure) is provided on the clamping plate 22, and the clamping hole is located at the second height of the door guard panel triangle block 2 along the vehicle body height direction, and the extension part 31 is provided with a tongue-shaped plate 311; the tongue-shaped plate 311 is located on the side of the extension part 31 facing the door guard panel triangle block 2; the tongue-shaped plate 311 is clamped in the clamping hole along the vehicle body height direction, thereby completing the clamping and fixing of the door guard panel triangle block 2 and the extension part 31.

Specifically, the depth direction of the clamping hole, i.e., the direction in which the clamping hole and the tongue-shaped plate 311 abut against each other after being clamped, is at a certain angle to the length and width plane of the vehicle body, so as to limit the displacement or deformation of the door panel triangle block 2 on the length and width plane of the vehicle body, thereby limiting the gap between the door panel triangle block 2 and other decorative panels, and improving the sealing of the triangular area between the window and the side pillar. The length and width plane of the vehicle body refers to the plane where the straight line in the length direction of the vehicle body and the straight line in the width direction of the vehicle body are located at the same height position in the height direction of the vehicle body. As an example, the depth direction of the clamping hole shown in FIG. 2 is perpendicular to the length and width plane of the vehicle body.

As an optional embodiment, the clamping plate 22 is integrally formed with the door guard plate triangle block 2. The integrally formed clamping plate 22 has the characteristics of high connection strength and easy preparation.

When the clamping plate 22 is specifically provided, some reinforcing structures may be provided in order to further enhance the connection strength between the clamping plate 22 and the door guard plate triangle block 2 .

As an optional embodiment, a clamping plate reinforcing rib 221 is provided at the connection between the clamping plate 22 and the door guard plate triangle block 2. Specifically, the clamping plate reinforcing rib 221 can be located on the side of the clamping plate 22 facing the door guard plate body 1, and the clamping plate reinforcing rib 221 simultaneously connects the clamping plate 22 and the door guard plate triangle block 2. The clamping plate reinforcing rib 221 has a guide surface 2211, which is an inclined surface. Specifically, the clamping plate 22 can be gradually inclined downward along the vehicle body height direction toward the plate body of the door guard plate triangle block 2. When the tongue-shaped plate 311 is clamped upward into the clamping hole, the guide surface 2211 can guide the tongue-shaped plate 311 to clamp into the clamping hole.

As an example, the clip plate reinforcement ribs 221 shown in FIG. 2 are three parallel clip plate reinforcement ribs 221, and each clip plate reinforcement rib 221 has a guide surface 2211 on the side away from the door guard plate triangular block 2. The three guide surfaces 2211 are parallel and together guide the tongue plate 311. Of course, in other optional embodiments, under the premise of satisfying the connection strength between the clip plate 22 and the door guard plate triangular block 2, the number of the triangular block reinforcement ribs 221 can also be other values, such as 1, 2, 4, 5, etc.

Some possible forms of the tongue-shaped plate 311 are described in detail below.

As an optional embodiment, the tongue-shaped plate 311 includes a snap-fitting portion 3111 and a connecting portion 3112. Specifically, the snap-fitting portion 3111 serves as a functional portion snap-fitted with the snap-fitting plate 22. The snap-fitting portion 3111 extends along the depth direction of the snap-fitting hole and is snap-fitted in the snap-fitting hole. The snap-fitting portion 3111 cooperates with the snap-fitting hole to limit the displacement of the door guard plate triangle block 2 along the width direction and the length direction of the vehicle body. The connecting portion 3112 connects the snap-fitting portion 3111 and the extension portion 31, maintains the snap-fitting portion 3111 in a relative relative position relative to the extension portion 31, and further maintains the door guard plate triangle block 2 and the extension portion 31 in a relatively determined position. Specifically, the snap-fitting portion 3111 and the connecting portion 3112 can be integrally formed, and the integrally formed snap-fitting portion 3111 and the connecting portion 3112 have the characteristics of stable and reliable connection and easy preparation.

As an optional embodiment, referring to FIG. 3 , the tongue-shaped plate 311 is formed by bending the extension part 31 as a whole. Specifically, the tongue-shaped plate 311 can be a strip-shaped portion along the height direction of the vehicle body on the extension part 31, and the width of the strip-shaped portion along the length direction of the vehicle body matches the size of the clamping hole along the length direction of the vehicle body. The strip-shaped portion is bent twice toward the door guard triangular block 2 and toward the depth direction of the clamping hole, forming the tongue-shaped plate 311 as shown in FIG. 3 . The tongue-shaped plate 311 formed as a whole with the extension part 31 can provide a strong connection strength, and no additional process is required to fix the tongue-shaped plate 311 to the extension part 31, which has the characteristics of being easy to produce.

Of course, the connection method between the tongue plate 311 and the extension portion 31 is not limited to the above-mentioned integral molding method.

As another possible implementation, the tongue-shaped plate 311 and the extension portion 31 can be welded and fixed. During welding, the tongue-shaped plate 311 may further include a fixing plate (not shown in the figure) for connecting with the engaging portion 3111, and the fixing plate and the extension portion 31 are attached and welded, so that the tongue-shaped plate 311 and the extension portion can be fixedly connected and have a high connection strength.

In order to further enhance the stability of the connection between the tongue plate 311 and the extension portion 31, some reinforcing structures may be provided between the tongue plate 311 and the extension portion 31. Optionally, a reinforcing rib (not shown in the figure) may be provided between the tongue plate 311 and the extension portion 31, and the reinforcing rib fixes the engaging portion 3111, the connecting portion 3112 and the extension portion 31, thereby reinforcing the fixing of the tongue plate 311 and reducing the risk of loosening of the engaging connection between the door guard plate triangle block 2 and the extension portion 31 due to deformation of the tongue plate 311.

Of course, the above-mentioned snap-fit fixation between the door guard panel triangular block 2 and the tongue-shaped plate 3111 is not the only way to fix the door guard panel triangular block 2 and the tongue-shaped plate. In other possible embodiments, a rivet plate (not shown in the figure) parallel to the snap-fit portion 3111 of the tongue-shaped plate 311 may be fixedly provided on the side of the door guard panel triangular block 2 facing the extension portion 31. The snap-fit portion 3111 of the tongue-shaped plate 311 is riveted and fixed to the rivet plate using rivets, thereby achieving a fixed connection between the door guard panel triangular block 2 and the extension portion 31.

An embodiment of the present application also provides a car, which includes a vehicle body and any one of the above-mentioned door guard plate assemblies arranged on the vehicle body.

The vehicle adopts an integrally formed door panel and a door panel triangle block, and the lower end of the door panel triangle block is integrally connected with the door panel body, so that a reliable connection is formed between the door panel triangle block and the door panel body, and the upper end of the door panel triangle block is clamped and fixed with the door sheet metal, so that the door panel triangle block is firmly fixed as a whole. There is no need to set an additional connection structure at the lower end of the door panel triangle block to connect with the door sheet metal, so there is no need to leave space for the additional connection structure, so that the size of the door panel triangle block can be further reduced to match the smaller triangular area between the window and the side pillar.
