Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a door assembly and a vehicle. Background Art

[0002] SUVs are very popular in the Chinese market due to their large space, strong passability and good vision. In order to ensure the aesthetics of the tailgate sheet metal, a tailgate interior guard plate is usually installed to cover it.

[0040] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0041] like Figure 1 and Figure 2 As shown, the first aspect of the present disclosure provides a vehicle door assembly. The vehicle door assembly includes a main panel 1, a reinforcement panel 2, a trim panel 3, a mounting cavity 4, and a wiper mechanism 5. The vehicle door assembly can be a side door assembly or a rear door assembly of a vehicle. This disclosure is not limited to these.

[0042] like Figure 3 As shown, the main plate 1 includes an upper edge 10, an outer surface 11 and an inner surface 12 arranged opposite to each other. The upper edge 10 is located at the top of the main plate 1. The upper edge 10 is provided with a notch 13 to provide installation space for the wiper mechanism 5. In addition, it is also possible to Figure 3 As can be seen, the inner surface 12 and the outer surface 11 of the main body panel 1 in the present disclosure are both uneven: on the one hand, they can increase the structural strength of the main body panel 1, and on the other hand, they are used to provide installation for other components such as the reinforcement panel 2 and the decorative panel 3.

[0043] Continue to refer Figure 1 and Figure 2, the reinforcing plate 2 is fixedly connected to the outer surface 11. The decorative panel 3 is fixedly connected to the inner surface 12 and the reinforcing plate 2, and at least covers the notch 13, thereby making the interior surface of the tailgate more beautiful. The installation cavity 4 is located between the notch 13, the reinforcing plate 2 and the decorative panel 3. The wiper mechanism 5 is at least partially located in the installation cavity 4 and is fixedly connected to the reinforcing plate 2. Among them, the decorative panel 3 in the present disclosure has a smooth and flat surface and a relatively small thickness. It mainly serves to decorate and beautify the inner side of the door assembly.

[0044] In traditional door assemblies, the trim panel 3 is mounted solely through a fixed connection to the main panel 1. Furthermore, several mounting points between the trim panel 3 and the main panel 1 must avoid the wiper mechanism 5. This results in significant distances between these mounting points, typically exceeding 300mm. During the existing on-vehicle matching process, alignment of one mounting point can lead to a significant gap between the remaining mounting points, increasing the gap between the trim panel 3 and the main panel 1. This can cause the trim panel 3 to wobble after installation, resulting in unusual noise.

[0045] The vehicle door assembly disclosed in the present invention facilitates the installation of the wiper mechanism 5 by adding a reinforcement plate 2 and providing a notch 13 on the main body plate 1. That is, the notch 13 provides a larger installation space for the wiper mechanism 5, and the reinforcement plate 2 is used to be fixedly connected to the wiper mechanism 5. On the other hand, although the reinforcement plate 2 and the decorative plate 3 are respectively located on the inner and outer sides of the main body plate 1, the notch 13 on the main body plate 1 allows the decorative plate 3 and the reinforcement plate 2 to be fixedly connected. In this way, the decorative plate 3, the reinforcement plate 2 and the main body plate 1 are all fixedly connected to each other, thereby forming a whole, thereby enhancing the structural strength of the entire vehicle door assembly. At the same time, the installation point spacing between the reinforcement plate 2 and the decorative plate 3 is small. During the actual vehicle matching process, the installation gap between the decorative plate 3 and the reinforcement plate 2 is also small, and the decorative plate 3 is not prone to shaking after installation.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments, the main panel 1 includes two first mounting structures 14. The two first mounting structures 14 are respectively located on either side of the notch 13 and are close to the notch 13. The trim panel 3 includes two second mounting structures 30 fixedly connected to the first mounting structures 14. In this way, by arranging the first mounting structures 14 close to the notch 13, the distance between the two first mounting structures 14 is reduced, so that the distance between the two first mounting structures 14 is controlled to be between 270 mm and 280 mm, thereby reducing the gap between the main panel 1 and the trim panel 3 during the actual vehicle matching process.

[0047] like Figure 4 and Figure 5As shown, in some embodiments, the reinforcing plate 2 includes at least two third mounting structures 20. The at least two third mounting structures 20 are located between the two sides of the notch 13. The decorative panel 3 includes at least two fourth mounting structures 31 fixedly connected to the third mounting structures 20. In this way, the third mounting structure 20 located between the two sides of the notch 13 on the reinforcing plate 2 is provided, which fully utilizes the gap of the wiper mechanism 5 itself, so that the gap between the two third mounting structures 20 can be controlled between 170 mm and 180 mm, thereby enhancing the stability of the installation of the decorative panel 3.

[0048] On the other hand, the distance between the third mounting structure 20 on the reinforcing plate 2 and the first mounting structure 14 on the nearest main body plate 1 will not exceed 200 mm, further ensuring the stability of the installation of the decorative plate 3.

[0049] In some embodiments, the trim panel 3 includes a first panel body 32 and a first raised portion 33 that rises away from the reinforcing plate 2. Providing the first raised portion 33 on the trim panel 3 not only increases the structural strength of the trim panel 3 but also provides more sufficient installation space for the wiper mechanism 5.

[0050] As an optional embodiment, the second mounting structure 30 is disposed on the first plate body 32 and near the first raised portion 33. The fourth mounting structure 31 is disposed on the first raised portion 33. The second mounting structure 30 and the fourth mounting structure 31 on the decorative panel 3 serve as the main stress-bearing areas of the decorative panel 3. Disposing them on the first raised portion 33 or near the first raised portion 33 can effectively improve the stress-bearing conditions of the decorative panel 3.

[0051] As an optional embodiment, at least two fourth mounting structures 31 and at least two second mounting structures 30 are not collinear. In this way, the stability of the connection between the decorative panel 3, the reinforcing panel 2 and the main body panel 1 can be further increased, and the shaking of the decorative panel 3 can be reduced.

[0052] Continue to refer Figure 3 In some embodiments, the first mounting structure 14 includes a first mounting hole 140 that cooperates with the second mounting structure 30. The third mounting structure 20 includes a second mounting hole 200 that cooperates with the fourth mounting structure 31. The axis of the second mounting hole 200 is parallel to the axis of the first mounting hole 140. The decorative panel 3 in the present disclosure is relatively thin and has an aesthetic effect. It cannot be connected to the main panel 1 and the reinforcement panel 2 by fasteners such as screws. In other words, the decorative panel 3 is mainly connected to the main panel 1 through the first mounting structure 14 and the second mounting structure 30 that are clamped to each other, and is connected to the reinforcement panel 2 through the third mounting structure 20 and the fourth mounting structure 31 that are clamped to each other. In this way, only when the axis of the second mounting hole 200 is parallel to the axis of the first mounting hole 140 can the decorative panel 3 be fixedly connected to the reinforcement panel 2 and the main panel 1 at the same time.

[0053] Continue to refer Figure 4 As an optional embodiment, the fourth mounting structure 31 includes a first mounting portion 310, a clamping portion 311 and a second mounting portion 322. The first mounting portion 310 is arranged on the decorative panel 3. The second mounting portion 322 is used to pass through the second mounting hole 200, and the clamping portion 311 is connected and arranged between the first mounting portion 310 and the second mounting portion 322. The clamping portion 311 is clamped and matched with the second mounting hole 200. Among them, the second mounting portion 322 is a conical structure and has a certain deformation ability, so that the second mounting portion 322 can be easily extended into the second mounting hole 200. At the same time, the diameter of the clamping portion 311 is smaller than the maximum diameter of the first mounting portion 310 and smaller than the maximum diameter of the second mounting portion 322, so that the clamping portion 311 can be clamped and matched with the second mounting hole 200.

[0054] It should be noted that the structures of the second mounting structure 30 and the fourth mounting structure 31 in the present disclosure may be the same or different. It is only necessary to ensure that the first mounting structure 14 and the second mounting structure 30 can be snap-fitted and fixed. The present disclosure does not limit this.

[0055] Continue to refer Figure 3 and Figure 5 In some embodiments, the main panel 1 includes a flange 15 provided on the upper edge 10. The reinforcing plate 2 includes a connecting portion 21 and a second plate body 22 for being fixedly connected to the wiper mechanism 5. The second plate body 22 is fixedly connected to the flange 15. The second plate body 22 includes a first edge 220 and a second edge 221 that are relatively arranged. The first edge 220 is close to the flange 15, and the third mounting structure 20 is provided on the first edge 220. The connecting portion 21 is provided on the second edge 221 and is fixedly connected to the main panel 1. A portion of the reinforcing plate 2 in the present disclosure is fixed to the main area of ​​the main panel 1, and the other portion is fixed to the flange 15 of the main panel 1, thereby forming a stable triangular structure. At the same time, the decorative panel 3 is fixed to the triangular structure through the cooperation of the third mounting structure 20 and the fourth mounting structure 31, which can make the installation of the decorative panel 3 more stable.

[0056] As an optional embodiment, the second plate body 22 includes a first reinforcing portion 222 and a second reinforcing portion 223 forming an L-shaped structure. The second reinforcing portion 223 is connected and arranged between the first reinforcing portion 222 and the connecting portion 21. The first reinforcing portion 222 is fixedly connected to the flange 15 and the wiper mechanism 5. The L-shaped second plate body 22 in the present disclosure can provide more installation space for the wiper mechanism 5 on the one hand, and enhance the structural strength of the reinforcing plate 2 itself on the other hand.

[0057] As an optional embodiment, the second plate body 22 also includes at least three third raised portions 224 provided on the first reinforcement portion 222. The third raised portion 224 rises in a direction away from the wiper mechanism 5. The third mounting structure 20 is provided between two adjacent third raised portions 224. Taking into account various factors such as the installation space, installation position, and installation strength of the door panel assembly, if the raised structure is not provided, the strength of the third mounting structure 20 will be insufficient. If the third mounting structure 20 is provided on the raised structure, the position limitation of the fourth mounting structure 31 will cause the fourth mounting structure 31 to be unable to cooperate with the third mounting structure 20. Therefore, in the present disclosure, by providing three third raised portions 224, the first reinforcement portion 222 becomes an uneven structure, thereby achieving the purpose of enhancing the strength of the third mounting structure 20. At the same time, the third raised portion 224 rises in a direction away from the wiper mechanism 5 in order to avoid the third raised portion 224 from encroaching on the installation space of the wiper mechanism 5.

[0058] Continue to refer Figure 5 In some embodiments, the third mounting structure 20 includes a lug 201. The lug 201 is connected to the first reinforcement portion 222 and to two adjacent third protrusions 224. The second mounting hole 200 is provided on the lug 201. Since it is necessary to ensure that the axis lines of the first mounting hole 140 and the second mounting hole 200 are parallel, in other words, the lug 201 needs to remain parallel to the main area of ​​the main plate 1, the setting angle of the lug 201 is determined, that is, an obtuse angle is formed between the lug 201 and the first reinforcement portion 222. At the same time, the first lug 201 is provided on the first reinforcement portion 222 to ensure that the lug 201 can be connected to the first reinforcement portion 222 and the two adjacent third protrusions 224, thereby ensuring that the lug 201 has sufficient structural strength and will not bend due to excessive force.

[0059] like Figure 6 As shown, in some embodiments, the wiper mechanism 5 includes a mounting plate 50, a motor 51, a gear assembly 54, a connecting rod 52, and a wiper member 53. The mounting plate 50 is fixedly connected to the first reinforcement portion 222. The motor 51 and the gear assembly 54 are mounted on the mounting plate 50. The mounting plate 50, the motor 51, and the gear assembly 54 are located within the mounting cavity 4, while the wiper member 53 is located outside the mounting cavity 4. The connecting rod 52 and the gear assembly 54 are transmission-connected between the motor 51 and the wiper member 53.

[0060] A second aspect of the present disclosure provides a vehicle (not shown). The vehicle includes the above-mentioned door assembly. The vehicle in the present disclosure can be either a passenger vehicle or a cargo vehicle. The present disclosure is not limited to this.
