And to ensure the anti-denting performance of the outer panel in the area between the outer panel reinforcement plate and the bumper beam, a door support plate extending in the front-rear direction of the vehicle is usually arranged between the outer panel reinforcement plate and the door bumper beam, or a plate-shaped member is arranged to replace the door support plate. However, the above door skeleton structure increases the weight of the door more, which does not meet the technical requirements of vehicle lightweighting. Summary of the Utility Model

[0003] In view of this, the utility model aims to provide a door support plate, which is beneficial to realizing the lightweight design of the door.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0010] Furthermore, the cross section of the door support plate is in a "J" shape.

[0011] Further, the multiple side plates include a first side plate, a second side plate and a third side plate which are respectively arranged adjacent to two ends of the first side plate; the first side plate is used for connecting with the door anti-collision beam, and the first side plate extends along the length direction of the door anti-collision beam; the sum of the included angle α between the first side plate and the second side plate and the included angle β between the first side plate and the third side plate is between 170° and 190°.

[0012] Further, the multiple side plates include a fourth side plate and a fifth side plate; the fourth side plate is used for connecting with the outer plate reinforcing plate, and the fourth side plate extends along the front-rear direction of the vehicle; the fifth side plate is connected between the third side plate and the fourth side plate, and the included angle between the third side plate and the door anti-collision beam is smaller than the included angle between the fifth side plate and the door anti-collision beam.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] (1) The door support plate of the utility model can replace the existing outer plate door support plate to strengthen the area of the door that needs to be strengthened. When applied to the door, it can prevent the outer panel of the door from vibrating and making abnormal noises under working conditions such as high-speed driving and slamming the door, and there will be no depression and vibration problems when pressing or knocking on the outer panel of the door. It can also better reduce the weight of the door, meeting the lightweight requirements of the vehicle.

[0025] (6) The aforementioned door support door is applied to the vehicle door, which can effectively reduce the weight of the vehicle door and ensure the rigidity of the door outer panel, so that the door outer panel will not vibrate or make abnormal noise under conditions such as high-speed driving or strong door slamming, and will not dent or vibrate when pressed or knocked by hand.

[0026] (7) The handle mounting portion is provided on the annular plate, which is equivalent to integrating a mounting structure for mounting the handle on the annular plate, thereby eliminating the need for a mounting bracket for mounting the handle, having a good weight reduction effect, and also helping to save working procedures, labor hours and labor costs.

[0027] (8) By limiting the value of the distance a between the front portion of the door anti-collision beam and the lower edge of the door, the stiffness of the area between the front portion of the door anti-collision beam and the front portion of the outer panel reinforcement plate on the door outer panel can be improved.

[0028] (9) The front part of the door anti-collision beam, the hinge reinforcement plate of the door and the inner door panel are welded together to form a three-layer stacked structure, which can better absorb energy when the door is hit, thereby improving the safety factor of the door. At least one of the door support plate, the outer panel reinforcement plate and the door anti-collision beam is connected to the door outer panel by bonding, which is convenient to connect and can better improve the rigidity of the door outer panel. The second groove can play a role in strengthening the structural strength of the outer panel reinforcement plate, and the third groove can play a role in strengthening the structural strength of the door anti-collision beam. At the same time, the second groove and the third groove can also accommodate adhesive, so that the second groove can improve the connection reliability of the outer panel reinforcement plate and the door outer panel, and the third groove can improve the connection reliability of the door anti-collision beam and the door outer panel.

[0029] In addition, another object of the present invention is to provide a vehicle provided with the above-mentioned vehicle door.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] Embodiment 1

[0051] The present embodiment relates to a vehicle door support plate 1, which can strengthen the area of ​​the vehicle door that needs to be strengthened, improve the NVH performance of the entire vehicle, and can effectively reduce the weight of the vehicle door, thereby facilitating the lightweighting of the entire vehicle.

[0052] In terms of overall structure, Figures 1 to 8 As shown, the vehicle door support plate 1 of this embodiment is used to be installed to the inner side of the vehicle door outer panel, and the vehicle door support plate 1 is arranged near the middle and rear part of the vehicle door in the front-rear direction of the vehicle.

[0053] In addition, a first connection portion is provided at the upper portion of the door support plate 1, and the first connection portion is used to connect to the lower side of the outer panel reinforcement plate 2 of the door. A second connection portion is provided at the lower portion of the door support plate 1, and the second connection portion is used to connect to the upper side of the door anti-collision beam 3 of the door. At the same time, an opening 18 is provided on the door support plate 1, so that the door support plate 1 is annular.

[0054] It is worth mentioning that, in the specific implementation, each door of the vehicle is provided with the door support plate 1 of the present embodiment to meet the requirement of weight reduction design of the door, and the general structure of each door is basically the same. In addition to the door support plate 1, each door includes a door inner panel 5, a door outer panel, and an outer panel reinforcement plate 2 and a door anti-collision beam 3 arranged between the door inner panel 5 and the door outer panel.

[0055] Therefore, for the convenience of introducing relevant content, in this embodiment, the left front door of the vehicle is specifically described. Figures 1 to 3 That is the schematic diagram of the left front door. However, it should be noted that, in order to clearly express the internal structure, Figures 1 to 3 the outer door panel is omitted.

[0056] Based on the above overall introduction, in this embodiment, specifically, as a preferred implementation form, as shown in Figure 4 Figure, the door support plate 1 includes a plurality of side plates, and the plurality of side plates are connected end to end in sequence. At the same time, the above-mentioned opening 18 is formed within the area surrounded by the plurality of side plates.

[0057] It can be understood that the door support plate 1 is formed by connecting a plurality of side plates into an annular structure, which can provide more support for a local area of the outer door panel. It can strengthen the stiffness of the area on the outer door panel corresponding to the door support plate 1, and also greatly improve the stiffness of the area on the outer door panel corresponding to the periphery of the door support plate 1. Moreover, on the basis of ensuring its own structural strength and stiffness, it can preferably reduce the self-weight, which is beneficial to reducing the weight of the door.

[0058] As a preferred implementation manner, a first groove 10 is formed on each side plate. The first groove 10 extends along the length direction of the side plate, and the first groove 10 is recessed toward the side away from the outer door panel. Here, setting the first groove 10 can, on the one hand, play a role in strengthening the structural strength of the support plate, and on the other hand, can also play a role in accommodating the adhesive when the door support plate 1 is connected to the outer door panel, thereby improving the connection reliability between the door support plate 1 and the outer door panel.

[0059] Here, the number and arrangement form of the first grooves 10 can be set and adjusted according to the actual bonding requirements between the door support plate 1 and the outer door panel. For example, each side plate is respectively provided with a first groove 10, etc.

[0060] In specific implementation, in this embodiment, as a preferred implementation form, the cross-section of the door support plate 1 is in a "U" shape. Here, making the cross-section of the door support plate 1 in a "U" shape can preferably strengthen the structural strength and stiffness of the door support plate 1 itself, which is beneficial to improving the structural strength and stiffness of the door.

[0061] Of course, the cross-section of the above-mentioned door support plate 1 being in a "U" shape means that the cross-sections of the respective side plates are in a "U" shape, and specifically means that it is approximately in a "U" shape visually, rather than the strict Chinese character "U". Each side plate or the door support plate 1 also forms a shape trend adapted to cooperate with components such as the outer plate reinforcement 2 and the door anti-collision beam 3 in specific implementation.

[0062] And, in this embodiment, as a preferred implementation form, in combination with Figure 4 and Figure 5 As shown, the plurality of side panels include a first side panel 11 , and a second side panel 12 and a third side panel 13 respectively arranged adjacent to two ends of the first side panel 11 .

[0063] The first side plate 11 is used to connect with the door anti-collision beam 3, the first side plate 11 extends along the length direction of the door anti-collision beam 3, the second side plate 12 is connected to the front end of the first side plate 11, and the third side plate 13 is connected to the rear end of the first side plate 11. At the same time, the sum of the angle α between the first side plate 11 and the second side plate 12 and the angle β between the first side plate 11 and the third side plate 13 is between 170° and 190°.

[0064] It can be understood that the larger the value of α+β is, the more support the door support plate 1 provides to the door outer panel. Conversely, the smaller the value of α+β is, the less support the door support plate 1 provides to the door outer panel. Limiting the value of α+β to between 170° and 190° can effectively improve the utilization rate of materials.

[0065] In specific implementation, in order to obtain a relatively good material utilization rate of the door support plate 1, the value of α+β can be preferably 170°, 180° or 190°, etc. At the same time, as a preferred implementation form, the second side plate 12 and the third side plate 13 are gradually inclined upward from front to back to facilitate the formation of an annular structure.

[0066] Secondly, in this embodiment, as a preferred implementation form, the plurality of side panels include a fourth side panel 14 and a fifth side panel 15. The fourth side panel 14 is used to connect with the outer panel reinforcement panel 2, and the fourth side panel 14 extends along the front-rear direction of the vehicle. The fifth side panel 15 is connected between the third side panel 13 and the fourth side panel 14, and the angle between the third side panel 13 and the door anti-collision beam 3 is smaller than the angle between the fifth side panel 15 and the door anti-collision beam 3.

[0067] In this way, by setting a fourth side panel 14 extending along the front-rear direction of the vehicle, it is convenient to connect with the existing outer panel reinforcement plate 2, and the angle between the third side panel 13 and the door anti-collision beam 3 is smaller than the angle between the fifth side panel 15 and the door anti-collision beam 3, which can reduce the coverage area of ​​the door support plate 1 on the door outer panel, thereby achieving the dual requirements of taking into account the structural door outer panel stiffness and reducing the weight of the door support plate 1 itself.

[0068] In the specific structure, the front end of the second side plate 12 of this embodiment is connected to the front end of the first side plate 11, the rear end of the second side plate 12 is connected to the front end of the fourth side plate 14, the front end of the third side plate 13 is connected to the rear end of the first side plate 11, the front end of the fifth side plate 15 is connected to the rear end of the third side plate 13, and the rear end of the fifth side plate 15 is connected to the rear end of the fourth side plate 14.

[0069] It is worth mentioning that welding is preferably used between the fourth side panel 14 and the outer panel reinforcement plate 2, and between the first side panel 11 and the door anti-collision beam 3, and in the specific implementation, a first support plate lap edge 141 for connecting to the outer panel reinforcement plate 2 is formed above the fourth side panel 14, and a first reinforcement plate lap edge 24 connected to the first support plate lap edge 141 is provided below the outer panel reinforcement plate 2.

[0070] A second support plate lap edge 111 for connecting to the door anti-collision beam 3 is provided below the first side plate 11, and a first anti-collision beam lap edge 31 connected to the second support plate lap edge 111 is provided on the door anti-collision beam 3. The first support plate lap edge 141 also constitutes the above-mentioned first connection portion. The second support plate lap edge 111 also constitutes the above-mentioned second connection portion.

[0071] Furthermore, the door support plate 1 of the present embodiment is preferably formed in one piece, and for the convenience of forming, a positioning hole 17 for forming positioning can be provided on the door support plate 1, so as to control the forming quality and realize standardized design and production. If necessary, the door support plate 1 can also be formed with a plurality of holes 17 according to the requirements of the door design or the arrangement of the wiring harness in the door. Figure 4 The harness mounting holes 16 etc. are shown.

[0072] The door support plate 1 of this embodiment can replace the existing outer panel door support plate 1, and strengthen the area of ​​the door that needs to be strengthened. It is applied to the door, so that the outer panel of the door will not vibrate or make abnormal noise under conditions such as high-speed driving and strong door slamming, and there will be no dents or vibrations when the outer panel of the door is pressed or knocked by hand. It can also effectively reduce the weight of the door, thereby meeting the lightweight requirements of the vehicle.

[0073] Embodiment 2

[0074] This embodiment relates to a vehicle door, which comprises a vehicle door inner panel 5 and a vehicle door outer panel which are buckled and connected together. The inner side of the vehicle door outer panel is provided with the vehicle door support plate 1 in the first embodiment.

[0075] Specifically, if Figure 1 and Figure 2 As shown, an outer panel reinforcement plate 2, a door support plate 1 of this embodiment and a front door anti-collision beam 3 are installed from top to bottom between the door outer panel and the door inner panel 5 of this embodiment. A window is provided on both the door outer panel and the door inner panel 5, and the outer panel reinforcement plate 2 is located at the lower side of the window and close to the window.

[0076] Furthermore, in this embodiment, as a preferred implementation form, Figure 6 As shown, the outer panel reinforcement plate 2 includes a horizontal plate 21 extending from front to rear, and an annular plate 22 connected to the rear portion of the horizontal plate 21 , and an inner edge of the annular plate 22 is provided with a mounting portion for mounting a handle.

[0077] Providing a handle mounting portion on the annular plate 22 is equivalent to integrating a mounting structure for mounting the handle on the annular plate 22, which can save the mounting bracket for mounting the handle, has a good weight reduction effect, and is also beneficial to saving processes, saving work hours and labor costs.

[0078] In specific implementation, the outer plate reinforcement plate 2 of this embodiment is integrally formed to improve the molding quality and realize standardized design and production. In order to improve the weight reduction, the outer plate reinforcement plate 2 may also be preferably formed with a plurality of reinforcement plate weight reduction holes 27. At the same time, the mounting portion may preferably be four handle mounting holes 23 arranged at intervals along the inner edge of the annular plate 22 to provide multiple mounting points for the handle or mounting bracket, thereby improving the installation reliability of the handle.

[0079] In addition, in this embodiment, as a preferred implementation form, Figure 3 and Figure 7 As shown, the door anti-collision beam 3 of the vehicle door gradually tilts downward from the front to the rear. The distance a between the front portion of the door anti-collision beam 3 and the lower edge of the vehicle door is between 350mm and 500mm.

[0080] By limiting the value of the distance a between the front of the door anti-collision beam 3 and the lower edge of the door, the stiffness of the area between the front of the door anti-collision beam 3 and the front of the outer panel reinforcement plate 2 on the door outer panel can be improved.

[0081] During the specific setting, the value of the distance a between the front part of the door anti-collision beam 3 and the lower edge of the door can be determined according to the actual dent resistance of the door outer panel. For example, the value of a can be preferably 442mm, and the door anti-collision beam 3 should pass through the dent resistance weak area of ​​the door outer panel as much as possible to facilitate enhancing the rigidity of the door outer panel.

[0082] In addition, in this embodiment, as a preferred implementation form, Figure 2 As shown, the front portion of the door anti-collision beam 3, the door hinge reinforcement plate 4 and the door inner panel 5 are welded together to form a three-layer stacked structure, which can better absorb energy when the door is collided, thereby improving the safety factor of the door.

[0083] In this embodiment, a lower overlap portion 42 may be provided on the hinge reinforcement plate 4 to be welded to the second anti-collision beam overlap edge 32 of the door anti-collision beam 3. If necessary, the hinge reinforcement plate 4 may also be welded to the outer panel reinforcement plate 2. For example, the front end of the outer panel reinforcement plate 2 is provided with a second reinforcement plate overlap edge 25, and the hinge reinforcement plate 4 is provided with an upper overlap portion 41 welded to the second reinforcement plate overlap edge 25. In addition, the outer panel reinforcement plate 2 may also be provided with a third reinforcement plate overlap edge 26 welded to the door inner panel 5.

[0084] At the same time, as a preferred implementation form, at least one of the door support plate 1, the outer plate reinforcement plate 2 and the door anti-collision beam 3 of this embodiment is connected to the door outer panel by bonding, and combined with Figure 6 and Figure 7 As shown, the outer panel reinforcement plate 2 is provided with a plurality of second grooves 20 extending along its length direction, and the door anti-collision beam 3 is provided with a plurality of third grooves 30 extending along its length direction, and each second groove 20 and each third groove 30 are recessed toward the side away from the door outer panel.

[0085] It can be understood that at least one of the door support plate 1, the outer plate reinforcement plate 2 and the door anti-collision beam 3 is connected to the door outer plate by bonding, which not only makes the connection convenient, but also can better improve the rigidity of the door outer plate;

[0086] The second groove 20 provided here can play a role in strengthening the structural strength of the outer panel reinforcement plate 2, and the third groove 30 can play a role in strengthening the structural strength of the door anti-collision beam 3. At the same time, the second groove 20 and the third groove 30 can also accommodate adhesive glue, so that the second groove 20 can improve the connection reliability between the outer panel reinforcement plate 2 and the door outer panel, and the third groove 30 can improve the connection reliability between the door anti-collision beam 3 and the door outer panel.

[0087] Specifically, the outer panel reinforcement plate 2 and the door outer panel, the door support plate 1 and the door outer panel, and the door anti-collision beam 3 and the door outer panel of this embodiment are preferably connected together by bonding. Specifically, shock-absorbing and expanding glue can be used to achieve bonding. After the shock-absorbing and expanding glue is baked, the dent resistance and rigidity of the door outer panel can be enhanced.

[0088] Among them, the positions of the shock-absorbing and expanding glue on the door support plate 1 can preferably be set to five places, and the five shock-absorbing and expanding glues are respectively located in the first grooves 10 on the first side plate 11 to the fifth side plate 15 to ensure the connection stability between the door support plate 1 and the door outer panel.

[0089] Furthermore, the number and arrangement of the second grooves 20 and the third grooves 30 can be set and adjusted according to the actual bonding requirements between the outer panel reinforcement plate 2, the door anti-collision beam 3 and the door outer panel. For example, the horizontal plate 21 in the outer panel reinforcement plate 2 is provided with a plurality of second grooves 20 arranged at intervals along the front and rear directions of the vehicle, and the annular plate 22 is provided with a plurality of second grooves 20 surrounding itself, etc.

[0090] In addition, shock-absorbing and expanding glue may preferably be provided around the mounting portion (i.e., along the extension direction of the annular plate 22). On the one hand, it can support the door outer panel and enhance the rigidity and dent resistance of the door outer panel. On the other hand, it can strengthen the connection between the door support plate 1 and the door outer panel, while also further enhancing the rigidity of the handle mounting point on the outer panel reinforcement plate 2.

[0091] The door support door in the first embodiment is applied to the door of the present embodiment, which can effectively reduce the weight of the door and ensure the rigidity of the door outer panel, so that the door outer panel will not vibrate or make abnormal noise under conditions such as high-speed driving or strong door slamming, and there will be no dents or vibrations when the door outer panel is pressed or knocked by hand.

[0092] In addition, this embodiment also relates to a vehicle, on which the above-mentioned vehicle door is provided.
