[0057] In the following, the utility model is specifically described by exemplary embodiments.However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0058] It should be noted that in the field of automobiles, the vehicle includes a vehicle body and a door assembly, and the door assembly is an important part of the vehicle body, which not only relates to the appearance and comfort of the vehicle, but also directly affects the safety and overall performance of the vehicle.The door assembly usually includes an outer plate and an inner plate, and the outer plate and the inner plate are fixed by edge covering, and the inner plate and the outer plate are edge covered to form an installation cavity in the middle, and the installation cavity is filled with key parts such as first reinforcing plate, second reinforcing plate and anti-collision beam.

[0059] In the prior art, the handle area cavity of the front door outer plate is large, and due to the high frequency of use of the door handle, this area has a risk of deformation, which affects the fine perception of the customer and causes a bad impression on the customer. Moreover, due to the wide door, only three cross beams are supported, and when the vehicle is subjected to side impact, the anti-collision ability of the vehicle is reduced, affecting the safety of the driver.

[0060] Based on this, the application provides a vehicle door assembly and a vehicle. A support plate is arranged in the handle area inside the door, and the support plate is connected in a manner and has a shape that enhances the strength of the outer plate at the handle and the overall strength of the door assembly, thereby solving the problem of deformation of the outer plate caused by high-frequency use of the handle.

[0061] In the following, embodiments of the application will be described in detail with reference to the accompanying drawings.

[0062] As shown in the accompanying Figures 1 to 8 In one illustrative embodiment of the door assembly of the application, the door assembly includes an outer plate 200, which is an external cover of the door and is directly exposed to the external environment, thereby protecting the internal structure of the door and improving the appearance of the vehicle.

[0063] In some embodiments, the door assembly includes an inner plate 100 arranged on one side of the outer plate 200, and a mounting cavity is formed between the outer plate 200 and the inner plate 100. The inner plate 100 is an internal structural member of the door, and the inner plate 100 and the outer plate 200 together form the main structure of the door, providing support and strength.

[0064] In some embodiments, the door assembly includes a window frame 101 located on one side of the inner plate 100; the window frame 101 is used to install the door glass, ensuring the sealing and sound insulation of the door.

[0065] In some embodiments, the door assembly includes a first reinforcing plate 300 arranged in the mounting cavity and close to the window frame 101. The first reinforcing plate 300 is used to improve the structural strength of the part of the door assembly close to the window frame 101, enhance the overall rigidity and stability of the door structure, effectively disperse external impact force, and reduce the risk of deformation of the window frame 101 area.

[0066] In some embodiments, the door assembly includes a door lock reinforcing plate 400 arranged in the mounting cavity. Its main function is to enhance the structural strength of the door lock area of the door, prevent deformation of the door lock part due to vibration or side impact during vehicle driving, ensure the normal function of the door lock and the sealing of the door, and at the same time improve the overall impact resistance of the door, ensuring the safety of the people in the vehicle.

[0067] In some embodiments, the vehicle door assembly comprises a support plate 600, the support plate 600 is arranged in the mounting cavity, and two ends of the support plate 600 are connected with the first reinforcing plate 300 and the door lock reinforcing plate 400 respectively; a containing area is formed between the support plate 600 and the first reinforcing plate 300. The vehicle door assembly further comprises a handle 201, the handle 201 is arranged on the outer plate 200, and the handle 201 is located within the containing area.

[0068] Through the above scheme, a support plate 600 is added to improve the strength of the vehicle door assembly and improve the anti-collision ability of the vehicle when subjected to side collision. The support plate 600 is added at the weak stress point of the handle 201, the cavity in the area of the handle 201 is large, and the risk of deformation of the outer plate 200 caused by high-frequency use of the handle 201 is reduced. Moreover, the added support plate 600 is connected to the first reinforcing plate 300 and the door lock reinforcing plate 400, and the two sides are flat and overlapped, the shape is more flexible, and the overlap position can be adjusted according to the collision level to meet the strain performance requirements of different regional regulations around the world.

[0069] It can be understood that when the vehicle door is installed on the vehicle body, the width direction of the vehicle door assembly is the front-rear direction of the vehicle. Therefore, the width direction of the inner plate 100 and the width direction of the outer plate 200 are the same as the width direction of the vehicle door assembly.

[0070] Please refer to Figures 1 to 4 In some embodiments, the window frame 101 is connected to one side of the top of the inner plate 100, and the window frame 101 and the inner plate 100 are in the same plane. The window frame 101 and the inner plate 100 can be integrally connected or welded.

[0071] Please refer to Figures 2 to 4 In some embodiments, the inner plate 100 and the outer plate 200 are connected to each other on both sides in the width direction. The bottom edges of the inner plate 100 and the outer plate 200 are connected to each other. The connection forms include but are not limited to edge covering, welding, riveting and the like. It can be understood that the central area of the inner plate 100 can be recessed away from the area of the outer plate 200, so as to form a mounting cavity between the inner plate 100 and the outer plate 200. The center of gravity area of the outer plate 200 can be recessed away from the area of the inner plate 100, so as to form a mounting cavity between the inner plate 100 and the outer plate 200.

[0072] In some embodiments, the top of the inner plate 100 and the outer plate 200 is not connected, so that the top of the mounting cavity is in communication with the outside, thereby realizing the installation and movement of the window glass.

[0073] Please refer to Figures 2 to 5In some embodiments, the first reinforcing plate 300 is in a long strip shape, and the length direction of the first reinforcing plate 300 is arranged along the width direction of the door assembly. The first reinforcing plate 300 can better disperse and withstand the impact force from the side, reducing the risk of deformation of the door when subjected to side impact.

[0074] In some embodiments, the first reinforcing plate 300 is in a rectangular plate shape, and the first reinforcing plate 300 is parallel to the inner plate 100. The rectangular plate shape provides a larger support area, enhancing the rigidity and stability of the door and effectively reducing the risk of deformation of the door during use due to external forces.

[0075] In another embodiment, the shape of the first reinforcing plate 300 can be tubular. The tubular structure has high bending and torsional stiffness, which can better disperse the impact force when subjected to side impact, protecting the internal structure of the door and the safety of the occupants. In addition, compared with the traditional plate structure, the tubular structure can provide higher strength under the same material usage, which helps to achieve lightweight design of the door, thereby reducing the overall weight of the vehicle, improving fuel economy and range.

[0076] Please refer to Figures 1 to 4 In some embodiments, the first reinforcing plate 300 is inclined from the direction away from the window frame 101 to the direction of the outer plate 200 and then extends away from the direction of the window frame 101. That is, the first reinforcing plate 300 first extends from top to bottom, then inclines to the direction of the outer plate 200, and then extends downward. Through this design, the support plate 600 is connected to the side of the first reinforcing plate 300 closest to the outer plate 200. This can make the support plate 600 closer to or fit the outer plate 200, thereby further improving the support of the accommodation area where the handle 201 is located, reducing the risk of deformation of the outer plate 200 caused by frequent use of the handle.

[0077] Please refer to Figures 2 to 4 In some embodiments, the edge of the inner plate 100 in the width direction is bent in the direction of the outer plate 200 to form a first flange and a second flange, and the two ends of the length direction of the first reinforcing plate 300 are connected to the first flange and the second flange, respectively. The connection strength is enhanced, and the overall structural stability of the door is improved. And it is convenient for the connection between the inner plate 100 and the outer plate 200 to form a mounting cavity.

[0078] Please refer to Figures 2 to 5 In some embodiments, the door lock reinforcing plate 400 is arranged on one side of the inner width direction of the door plate assembly. It is convenient for the door lock to be connected with the vehicle body after installation.

[0079] In some embodiments, the door lock reinforcing plate 400 is close to the first flange, and the door lock reinforcing plate 400 is connected to the first flange. It is convenient for the connection of the first reinforcing plate 300 and the door lock reinforcing plate 400.

[0080] In some embodiments, the door lock reinforcing plate 400 comprises a first connecting section and a second connecting section perpendicular to each other, the first connecting section is attached to and connected with one side of the inner plate 100 parallel to the outer plate 200, and the second connecting section is attached to and connected with the first flange. The connection strength of the door lock area and the overall structure of the door is enhanced, and the impact resistance and deformation resistance of the door in the door lock area are also improved by dispersing the stress points. At the same time, the bending design can also better adapt to the layout of the internal space of the door, optimize the compactness of the structure, and ensure that the door assembly realizes higher strength and stability in a limited space.

[0081] In some embodiments, one end of the support plate 600 is connected to the second connecting section of the door lock reinforcing plate 400. Specifically, the support plate 600 is connected to the side of the second connecting section away from the first connecting section, thereby completing the connection of the support plate 600 and realizing that the support plate 600 is parallel to the outer plate 200.

[0082] In some embodiments, the door lock reinforcing plate 400 further comprises a third connecting section connected to the side of the second connecting section away from the first connecting section. The third connecting section is parallel to the second connecting section. Specifically, the third connecting section extends in the direction of the interior of the door plate assembly. The support plate 600 is attached to and connected with the third connecting section. In this way, the support plate 600 and the door lock reinforcing plate 400 are stably connected, and this connection method is convenient for manual operation.

[0083] In some embodiments, the door lock reinforcing plate 400 is an integrally formed structure, which can be a plate-shaped structure bent and formed. The structural strength of the door lock reinforcing plate 400 is improved, and the possibility of its fracture is reduced.

[0084] Please refer to Figures 2 to 5 In some embodiments, the support plate 600 is arranged in a curved manner, and the center of the curvature is directed towards the first reinforcing plate 300. Through this arrangement, the support plate 600 can better surround the first reinforcing plate 300 to form an accommodation area. The range of the accommodation area will not be too large, so as to provide better support effect at the handle 201. The curved arrangement of the support plate 600 can effectively disperse external impact force, improve the pressure resistance of the door during side collision, and reduce the risk of deformation. In addition, this design improves the support and protection of the accommodation area, further reducing the risk of deformation of the outer plate 200 caused by high-frequency use of the handle 201.

[0085] In some embodiments, the curvature of the support plate 600 gradually increases from the direction close to the first reinforcing plate 300. The gradually increasing curvature of the support plate 600 from the direction close to the first reinforcing plate 300 can better adapt to the stress condition of the vehicle door, improving the strength and stability of the overall structure. This design not only enhances the anti-deformation ability of the vehicle door, but also optimizes the structural layout of the vehicle door, enabling it to maintain good performance under different collision levels. Moreover, it can better enclose the accommodation area.

[0086] In another embodiment, the curvature of the support plate 600 gradually increases from the direction close to the door lock reinforcing plate 400.

[0087] In some embodiments, the curvature of the support plate 600 can be the same everywhere. That is, the bending direction of the support plate 600 is the circular arc of concentric circles.

[0088] In some embodiments, the support plate 600 has a reinforcing cavity recessed therein, and the length direction of the reinforcing cavity extends along the length direction of the support plate 600. The provision of the reinforcing cavity improves the bending resistance of the support plate 600.

[0089] Specifically, the two sides of the support plate 600 in the width direction are inclined inwardly toward the direction of the inner panel 100, so that a reinforcing cavity is formed in the middle part of the support plate 600. The two sides of the support plate 600 in the width direction are also bent away from each other to have third flanges. The third flanges are attached to and connected with the first reinforcing plate 300, and the third flanges are attached to and connected with the door lock reinforcing plate 400, improving the stability of the connection and facilitating manual welding, riveting or bolt connection, and installation.

[0090] In some embodiments, the side of the support plate 600 facing the outer panel 200 is attached to the outer panel 200. This enhances the dent resistance of the vehicle door, ensuring that the outer panel 200 of the vehicle door can resist local denting and deformation when subjected to external loads. It can better support the outer panel 200 when impacted, improving the anti-collision effect.

[0091] Specifically, the side of the support plate 600 away from the inner panel 100 is attached to the side of the outer panel 200 facing the inner panel 100.

[0092] In some embodiments, the support plate 600 can have a weight-reducing hole. This reduces the weight of the support plate 600 while ensuring the structural strength of the support plate 600, achieving lightweight of the vehicle door assembly.

[0093] In some embodiments, the support plate 600 can have a connecting hole. The connecting hole can be connected to the outer panel 200 or the inner panel 100 to improve the connection strength and stability of the support plate 600 in the vehicle door assembly.

[0094] In another embodiment, the support plate 600 can be connected to other structures in the mounting cavity through the connecting holes, so as to improve the structural strength in the door assembly.

[0095] Please refer to Figures 2 to 5 In some embodiments, a hinge reinforcing plate 500 is arranged in the mounting cavity, the hinge reinforcing plate 500 is connected with the second flange, and the first reinforcing plate 300 is further connected with the hinge reinforcing plate 500 at one end close to the second flange. The door assembly needs to be hinged to the vehicle body, so the hinge reinforcing plate 500 is arranged in the mounting cavity to enhance the strength of the hinge part of the door and improve the durability and safety of the door. This design effectively reduces the risk of damage at the hinge and ensures the stability of the door during long-term use, thereby improving the safety of the vehicle. Through the connection of the hinge reinforcing plate 500 and the first reinforcing plate 300, the connection stability of the first reinforcing plate 300 is further improved.

[0096] Specifically, the hinge reinforcing plate 500 is partially connected to one side of the inner plate 100 parallel to the outer plate 200, and the hinge reinforcing plate 500 is further partially connected to one side of the second flange facing the first flange.

[0097] In some embodiments, the hinge reinforcing plate 500 can also be partially connected to the window frame 101, so as to further improve the connection strength of the hinge reinforcing plate 500 in the door assembly.

[0098] In some embodiments, a second reinforcing plate 700 is further arranged in the mounting cavity, and the second reinforcing plate 700 is located on the side of the support plate 600 away from the first reinforcing plate 300. Through the arrangement of the second reinforcing plate 700, the compression resistance of the door is further improved, and the protection performance of the door in the collision is enhanced. This design optimizes the structural layout of the door, so that the door can maintain good performance under different collision levels and ensure the safety of the passengers.
