Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a door assembly and a vehicle. Background Technology

[0002] In existing technology, door glass is fitted within the door window frame sheet metal and door trim panel, with the outer surface of the glass lower than the sheet metal and trim panel surfaces, creating a stepped surface difference. When the vehicle is traveling at high speeds, vortices are generated at this stepped area, leading to wind noise and increasing the drag coefficient, thus increasing energy consumption. A zero-surface-difference door design creates a continuous, smooth surface between the door and the side of the vehicle body, enhancing the overall sense of unity and refinement, and improving the vehicle's appearance and visual appeal. However, zero-surface-difference doors present challenges in assembly, requiring high precision. Utility Model Content

[0003] In view of this, the present invention provides a door assembly that reduces the assembly difficulty of the door assembly, improves the overall structural strength and rigidity of the door assembly, and enhances the assembly efficiency and quality of the door assembly.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] In a first aspect, this utility model provides a car door assembly, including: an outer door panel, an inner door panel, an upper reinforcing plate on the outer panel and a lower reinforcing plate on the outer panel, wherein the upper reinforcing plate on the outer panel is connected to the outer door panel, the lower reinforcing plate on the outer panel is connected to the inner door panel, the inner door panel is fastened to the outer door panel, and the upper reinforcing plate on the outer panel is connected to the lower reinforcing plate on the outer panel.

[0006] According to the present invention, the inner panel of the door is connected to the upper reinforcing plate and the lower plate of the outer panel to form a module, and the outer panel of the door is connected to the upper reinforcing plate to form a module. In this way, the assembly of the door assembly can be achieved simply by fastening the inner panel and the outer panel of the door together, which reduces the assembly difficulty of the door assembly, improves the overall structural strength and rigidity of the door assembly, and enhances the assembly efficiency and quality of the door assembly.

[0007] In one possible implementation of this utility model, a first connecting portion is formed on the upper reinforcing plate of the outer plate, and a second connecting portion is formed on the lower reinforcing plate of the outer plate. The upper reinforcing plate of the outer plate and the lower reinforcing plate of the outer plate are connected by the first connecting portion and the second connecting portion.

[0008] In this way, the connection between the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate is achieved through the cooperation of the first connecting part and the second connecting part. This allows the upper reinforcing plate on the outer plate to be connected to the lower reinforcing plate on the outer plate more stably, avoiding the situation where the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate separate. At the same time, it facilitates assembly and maintenance, and reduces the assembly and maintenance difficulty of the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate.

[0009] In one possible implementation of this utility model, the first connecting part is formed as a connecting nut, the second connecting part is formed as a connecting hole, and the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate are connected to the connecting nut by fasteners passing through the connecting hole.

[0010] In this way, by fastening the fasteners through the connecting holes and screwing them tightly to the connecting nuts, the connection difficulty between the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate is reduced, the connection steps between the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate are simplified, and the assembly efficiency of the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate is improved.

[0011] In one possible implementation of this utility model, the connecting nuts include a plurality of nuts, which are arranged at intervals in the X direction, and the connecting holes are arranged in a one-to-one correspondence with the connecting nuts.

[0012] In this way, by setting multiple connecting nuts, the connection strength between the upper reinforcing plate on the outer plate and the lower reinforcing plate on the outer plate is improved, the force is distributed, and local stress concentration is prevented. The multiple connecting holes and multiple connecting nuts are arranged one-to-one to ensure assembly accuracy and improve structural stability and reliability.

[0013] In one possible implementation of this utility model, a first flange is formed on the lower edge of the window frame position of the outer panel of the car door, and a second flange is formed on the reinforcing plate of the outer panel, with the first flange and the second flange overlapping and connected.

[0014] Thus, by setting the first and second flanges, the contact area between the outer door panel and the reinforcing plate on the outer panel is increased, improving the connection strength and stability. Furthermore, the first flange increases the local stiffness of the window frame of the outer door panel, preventing deformation of the window frame, while the second flange increases the structural strength of the reinforcing plate on the outer panel.

[0015] In one possible implementation of this utility model, a third connecting portion is formed on the lower plate of the reinforcing plate on the outer plate, and a fourth connecting portion is formed on the inner plate of the door. The upper plate of the reinforcing plate on the outer plate and the inner plate of the door are connected by the third connecting portion and the fourth connecting portion.

[0016] In this way, the connection between the lower reinforcing plate on the outer panel and the inner door panel is achieved through the cooperation of the third and fourth connecting parts. This allows the lower reinforcing plate on the outer panel to be more stably connected to the inner door panel, avoiding the situation where the lower reinforcing plate on the outer panel separates from the inner door panel. At the same time, it facilitates assembly and maintenance and reduces the assembly difficulty between the upper reinforcing plate on the outer panel and the inner door panel.

[0017] In one possible implementation of this utility model, at least one side edge of the inner door panel is formed with a first overlapping portion, and at least one side edge of the outer door panel is correspondingly formed with a second overlapping portion. The inner door panel and the outer door panel are connected by the first overlapping portion and the second overlapping portion.

[0018] Thus, by setting the first overlapping part and the second overlapping part, the snap-fit ​​connection between the inner door panel and the outer door panel is realized, which increases the contact area between the inner door panel and the outer door panel and improves the connection strength and connection stability.

[0019] In one possible implementation of this utility model, an installation port is formed on the inner panel of the car door, and the installation port includes multiple ports, which are arranged in a one-to-one correspondence with the connection hole.

[0020] Thus, by setting an installation port on the inner panel of the door, tools can easily be inserted into the inner panel for tightening or disassembly operations. Fasteners pass through the installation port and enter the connecting hole to be screwed into the connecting nut. The installation port provides assembly space for tools, reduces assembly difficulty, and improves assembly quality and efficiency.

[0021] In one possible implementation of this utility model, the reinforcing plate on the outer panel is connected to the outer panel of the car door by a rolled edge.

[0022] In this way, the reinforcing plate on the outer panel of the door is connected to the outer panel of the door by rolling, which can achieve a high-strength connection without welding, avoiding thermal deformation. The rolling structure embedded in the reinforcing plate on the outer panel improves the local rigidity of the door, enhances its bending and torsional resistance, and improves the aesthetics of the door assembly.

[0023] Secondly, this utility model provides a vehicle including the door assembly provided in any of the embodiments of the first aspect above.

[0024] The vehicle provided in this embodiment of the utility model, since it includes the door assembly provided in any of the first aspects above, has the same technical effect. That is, the inner door panel and the lower reinforcing plate of the outer door are connected to form a module, and the outer door panel and the upper reinforcing plate of the outer door are connected to form a module. In this way, the assembly of the door assembly can be realized by simply fastening the inner door panel and the outer door panel together, which reduces the assembly difficulty of the door assembly, improves the overall structural strength and rigidity of the door assembly, and enhances the assembly efficiency and quality of the door assembly. At the same time, it ensures the overall sense and refinement of the vehicle body, as well as the appearance quality and visual appeal of the vehicle. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the specific technical solutions of this utility model will be further described in detail below with reference to the accompanying drawings of the embodiments of this utility model. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0039] In the embodiments of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0040] Furthermore, in this embodiment of the invention, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0041] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0042] In embodiments of this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0043] In this embodiment of the invention, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

[0044] In traditional car door designs, the door glass is fitted within the door frame sheet metal and door trim panel, with the outer surface of the glass lower than the sheet metal and trim surface, creating a stepped surface difference. When the vehicle is traveling at high speeds, this stepped area creates vortices, leading to wind noise and increasing the drag coefficient, thus increasing energy consumption. Zero-surface-difference door designs create a continuous, smooth surface between the door and the body side, enhancing the overall look and refinement of the vehicle and improving its appearance and visual appeal. However, zero-surface-difference doors present challenges in assembly, requiring high precision.

[0045] In view of this, the present invention provides a door assembly that effectively solves the problem of high assembly difficulty in zero-surface-difference doors.

[0046] It should be noted that the vehicles or automobiles mentioned in this utility model can refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to the vehicle type, the vehicles or automobiles in this utility model can be sedans, off-road vehicles, multi-purpose vehicles (MPVs), or other types of vehicles.

[0047] The following is for reference. Figures 1-6 A door assembly 100 according to an embodiment of the present utility model is described.

[0048] Specifically, the door assembly 100 includes: an outer door panel 1, an inner door panel 2, an upper reinforcing plate 3 on the outer door panel, and a lower reinforcing plate 4 on the outer door panel. The upper reinforcing plate 3 on the outer door panel is connected to the outer door panel 1, and the lower reinforcing plate 4 on the outer door panel is connected to the inner door panel 2. The inner door panel 2 is fastened to the outer door panel 1, and the upper reinforcing plate 3 on the outer door panel is connected to the lower reinforcing plate 4. Thus, the inner door panel 2 and the lower reinforcing plate 4 on the outer door panel are connected to form a module, and the outer door panel 1 and the upper reinforcing plate 3 on the outer door panel are connected to form a module. In this way, the assembly of the door assembly 100 can be achieved simply by fastening the inner door panel 2 to the outer door panel 1, which reduces the assembly difficulty of the door assembly 100, improves the overall structural strength and rigidity of the door assembly 100, and enhances the assembly efficiency and quality of the door assembly 100.

[0049] Understandably, the upper reinforcing plate 3 on the outer panel is connected to the outer door panel 1, the lower reinforcing plate 4 on the outer panel is connected to the inner door panel 2, the upper reinforcing plate 3 on the outer panel is connected to the lower reinforcing plate 4 on the outer panel, the inner door panel 2 is fastened to the outer door panel 1, and the inner door panel 2 and the outer door panel 1 are connected by fastening to form a closed space for accommodating components such as windows and audio equipment. The upper reinforcing plate 3 on the outer panel is also connected to the lower reinforcing plate 4 on the outer panel, together forming a stable overall structure to ensure that the door can effectively protect the passengers inside the vehicle when it is impacted.

[0050] like Figures 1-4 As shown, the upper reinforcing plate 3 on the outer panel is connected to the outer door panel 1. The upper reinforcing plate 3 on the outer panel is located at the lower edge of the window frame position 11 of the outer door panel 1. The upper reinforcing plate 3 on the outer panel and the outer door panel 1 together form the lower edge of the window frame position 11. The lower reinforcing plate 4 on the outer panel is connected to the inner door panel 2. The inner door panel 2 is fastened to the outer door panel 1. The upper reinforcing plate 3 on the outer panel and the lower reinforcing plate 4 on the outer panel are connected. Under the premise of ensuring structural strength, the weight of the door assembly 100 is reduced.

[0051] According to the embodiment of the present utility model, the door assembly 100 is formed by connecting the inner door panel 2 and the outer door upper reinforcing plate and lower plate 4 to form a module, and the outer door panel 1 and the outer door upper reinforcing plate and upper plate 3 to form a module. In this way, the assembly of the door assembly 100 can be realized by simply fastening the inner door panel 2 and the outer door panel 1 together, which reduces the assembly difficulty of the door assembly 100, improves the overall structural strength and rigidity of the door assembly 100, and improves the assembly efficiency and assembly quality of the door assembly 100.

[0052] In some embodiments of this utility model, a first connecting portion is formed on the upper reinforcing plate 3 of the outer plate, and a second connecting portion is formed on the lower reinforcing plate 4 of the outer plate. The upper reinforcing plate 3 and the lower reinforcing plate 4 of the outer plate are connected by the first connecting portion and the second connecting portion. Thus, the connection between the upper reinforcing plate 3 and the lower reinforcing plate 4 of the outer plate is realized through the cooperation of the first connecting portion and the second connecting portion, so that the upper reinforcing plate 3 and the lower reinforcing plate 4 of the outer plate can be connected more stably, avoiding the possibility of separation between the upper reinforcing plate 3 and the lower reinforcing plate 4 of the outer plate. At the same time, it facilitates assembly and maintenance, and reduces the assembly and maintenance difficulty of the upper reinforcing plate 3 and the lower reinforcing plate 4 of the outer plate.

[0053] Reference Figures 4-6 As shown, it can be understood that the first connecting part is formed on the upper reinforcing plate 3 of the outer plate, and the second connecting part is formed on the lower reinforcing plate 4 of the outer plate. The first connecting part and the second connecting part cooperate to connect the upper reinforcing plate 3 of the outer plate and the lower reinforcing plate 4 of the outer plate.

[0054] In some embodiments of this utility model, the first connecting part is formed as a connecting nut 31, and the second connecting part is formed as a connecting hole 41. The upper reinforcing plate 3 and the lower reinforcing plate 4 on the outer plate are connected to the connecting nut 31 by fasteners 5 passing through the connecting hole 41. Therefore, by fastening the fasteners 5 through the connecting hole 41 and the connecting nut 31, the connection difficulty between the upper reinforcing plate 3 and the lower reinforcing plate 4 on the outer plate is reduced, the connection steps between the upper reinforcing plate 3 and the lower reinforcing plate 4 on the outer plate are simplified, and the assembly efficiency of the upper reinforcing plate 3 and the lower reinforcing plate 4 on the outer plate is improved.

[0055] Reference Figure 4 As shown, it can be understood that the connecting nut 31 is formed on the upper plate 3 of the outer plate and the connecting hole 41 is formed on the lower plate 4 of the outer plate. The connecting nut 31 corresponds to the connecting hole 41. The fastener 5 first passes through the connecting hole 41 of the lower plate 4 of the outer plate and then the fastener 5 is connected to the connecting nut 31 so that the upper plate 3 of the outer plate and the lower plate 4 of the outer plate are connected.

[0056] In some embodiments of this utility model, multiple connecting nuts 31 are included, and the multiple connecting nuts 31 are arranged at intervals in the X direction, with connecting holes 41 arranged in a one-to-one correspondence with the connecting nuts 31. Therefore, by providing multiple connecting nuts 31, the connection strength between the upper plate 3 of the outer plate and the lower plate 4 of the outer plate is improved, the stress is distributed, and local stress concentration is prevented. The one-to-one correspondence between the multiple connecting holes 41 and the multiple connecting nuts 31 ensures assembly accuracy and improves structural stability and reliability.

[0057] Reference Figure 5 and Figure 6 As shown, it can be understood that there are four connecting nuts 31, which are arranged at intervals in the X direction (front and back direction). There are also four connecting holes 41, which are arranged at intervals in the X direction (front and back direction). The four connecting nuts 31 and the four connecting holes 41 are arranged in a one-to-one correspondence. Each connecting hole 41 allows a fastener 5 to pass through, and the fastener 5 passes through the connecting hole 41 and is screwed into the corresponding connecting nut 31.

[0058] In some embodiments of this utility model, a mounting opening 21 is formed on the inner door panel 2. Multiple mounting openings 21 are arranged in a one-to-one correspondence with the connecting holes 41. Therefore, by providing mounting openings 21 on the inner door panel 2, tools can easily penetrate the inner door panel 2 for tightening or disassembling operations. Fasteners 5 pass through the mounting openings 21 and enter the connecting holes 41 to be screwed onto the connecting nut 31. The mounting openings 21 provide assembly space for tools, reducing assembly difficulty and improving assembly quality and efficiency.

[0060] In some embodiments of this utility model, a first flange 12 is formed on the lower edge of the window frame position 11 of the outer door panel 1, and a second flange 32 is formed on the upper reinforcing plate 3 of the outer door panel. The first flange 12 and the second flange 32 are overlapped and connected. Thus, by providing the first flange 12 and the second flange 32, the contact area between the outer door panel 1 and the upper reinforcing plate 3 of the outer door panel is increased, improving the connection strength and connection stability. Furthermore, the first flange 12 increases the local stiffness of the window frame portion of the outer door panel 1, preventing deformation of the window frame, and the second flange 32 increases the structural strength of the upper reinforcing plate 3 of the outer door panel.

[0061] Reference Figure 4 As shown, it can be understood that the first flange 12 is formed on the outer panel 1 of the door, and the first flange 12 is located on the lower edge of the window frame position 11. The second flange 32 is formed on the upper edge of the reinforcing plate 3 on the outer panel, and the first flange 12 and the second flange 32 are connected by overlap.

[0062] Furthermore, a groove is formed between the first flange 12 and the outer door panel 1, and the second flange 32 extends into the groove to define the relative positions of the outer door panel 1 and the reinforcing plate 3 on the outer door panel in the vertical direction and the relative positions of the outer door panel 1 and the reinforcing plate 3 on the outer door panel in the horizontal direction.

[0063] In some embodiments of this utility model, a third connecting portion is formed on the lower reinforcing plate 4 of the outer upper panel, and a fourth connecting portion is formed on the inner door panel 2. The upper reinforcing plate 3 of the outer upper panel and the inner door panel 2 are connected by the cooperation of the third connecting portion and the fourth connecting portion. Thus, the connection between the lower reinforcing plate 4 of the outer upper panel and the inner door panel 2 is realized through the cooperation of the third connecting portion and the fourth connecting portion, so that the lower reinforcing plate 4 of the outer upper panel can be more stably connected to the inner door panel 2, avoiding the possibility of the lower reinforcing plate 4 of the outer upper panel and the inner door panel 2 detaching. At the same time, it facilitates assembly and maintenance and reduces the assembly difficulty between the lower reinforcing plate 4 of the outer upper panel and the inner door panel 2.

[0064] Reference Figure 2 As shown, it can be understood that the third connecting part is formed as the first welding surface 42, and the fourth connecting part is formed as the second welding surface. The lower reinforcing plate 4 on the outer upper plate and the inner door panel 2 are welded together through the first welding surface 42 and the second welding surface. The first welding surface 42 and the second welding surface increase the contact area between the lower reinforcing plate 4 on the outer upper plate and the inner door panel 2, thereby improving the connection strength and connection stability between the lower reinforcing plate 4 on the outer upper plate and the inner door panel 2.

[0065] In some embodiments of the present invention, at least one side edge of the inner door panel 2 is formed with a first overlapping portion 22, and at least one side edge of the outer door panel 1 is correspondingly formed with a second overlapping portion. The inner door panel 2 and the outer door panel 1 are connected by the first overlapping portion 22 and the second overlapping portion. It is understood that the first overlapping portion 22 can be formed on one of the front, rear, upper, and lower edges of the inner door panel 2, or the first overlapping portion 22 can be formed on two of the front, rear, upper, and lower edges of the inner door panel 2, or the first overlapping portion 22 can be formed on three of the front, rear, upper, and lower edges of the inner door panel 2, or the first overlapping portion 22 can be formed on all four of the front, rear, upper, and lower edges of the inner door panel 2. A second overlapping portion is formed on the outer door panel 1, and the second overlapping portion is correspondingly provided with the first overlapping portion 22. By providing the first overlapping portion 22 and the second overlapping portion, the snap-fit ​​connection between the inner door panel 2 and the outer door panel 1 is realized, the contact area between the inner door panel 2 and the outer door panel 1 is increased, and the connection strength and connection stability are improved.

[0066] Reference Figure 3 As shown, the front, rear, and lower edges of the inner door panel 2 are each formed with a first overlapping portion 22, and the front, rear, and lower edges of the outer door panel 1 are each formed with a second overlapping portion. The first overlapping portion 22 of the front edge of the inner door panel 2 is connected to the second overlapping portion of the front edge of the outer door panel 1. The first overlapping portion 22 of the rear edge of the inner door panel 2 is connected to the second overlapping portion of the rear edge of the outer door panel 1. The first overlapping portion 22 of the lower edge of the inner door panel 2 is connected to the second overlapping portion of the lower edge of the outer door panel 1.

[0067] In some embodiments of this utility model, the reinforcing plate 3 on the outer panel is connected to the outer door panel 1 by a rolled edge. Thus, the reinforcing plate 3 on the outer door panel 1 is connected to the outer door panel 1 by a rolled edge, achieving a high-strength connection without welding, avoiding thermal deformation. The rolled edge structure embedded in the reinforcing plate 3 on the outer panel improves the local rigidity of the door, enhances its resistance to bending and torsion, and improves the aesthetics of the door assembly 100.

[0068] Secondly, this utility model provides a vehicle including the door assembly 100 provided in any of the embodiments of the first aspect above.

[0069] The vehicle provided in this embodiment of the utility model, since it includes the door assembly 100 provided in any of the embodiments of the first aspect above, has the same technical effect. That is, the inner door panel 2 and the lower reinforcing plate 4 of the outer door are connected to form a module, and the outer door panel 1 and the upper reinforcing plate 3 of the outer door are connected to form a module. In this way, the assembly of the door assembly 100 can be realized by simply fastening the inner door panel 2 and the outer door panel 1 together, which reduces the assembly difficulty of the door assembly 100, improves the overall structural strength and rigidity of the door assembly 100, and improves the assembly efficiency and assembly quality of the door assembly 100. At the same time, it ensures the overall sense and refinement of the vehicle body, as well as the appearance quality and visual appeal of the vehicle.

The first connecting portion is formed as a connecting nut 31, and the second connecting portion is formed as a connecting hole 41. The connecting nut 31 is formed on the upper reinforcing plate 3 of the outer plate, and the connecting hole 41 is formed on the lower reinforcing plate 4 of the outer plate. The connecting nut 31 corresponds to the connecting hole 41. The fastener 5 first passes through the connecting hole 41 of the lower reinforcing plate 4 of the outer plate, and then the fastener 5 is connected to the connecting nut 31 so that the upper reinforcing plate 3 of the outer plate is connected to the lower reinforcing plate 4 of the outer plate.

[0074] Four connecting nuts 31 are arranged at intervals in the X direction (front-to-back direction). Four connecting holes 41 are also arranged at intervals in the X direction (front-to-back direction). Each connecting nut 31 corresponds to one of the four connecting holes 41. Each connecting hole 41 allows a fastener 5 to pass through, and the fastener 5 passes through the connecting hole 41 and is screwed onto the corresponding connecting nut 31.

The third connecting portion forms a first welding surface 42, and the fourth connecting portion forms a second welding surface. The lower reinforcing plate 4 of the outer upper panel and the inner door panel 2 are welded together through the first welding surface 42 and the second welding surface. The first welding surface 42 and the second welding surface increase the contact area between the lower reinforcing plate 4 of the outer upper panel and the inner door panel 2, thereby improving the connection strength and connection stability between the lower reinforcing plate 4 of the outer upper panel and the inner door panel 2. The front, rear, and lower edges of the inner door panel 2 each have a first overlapping portion 22, and the front, rear, and lower edges of the outer door panel 1 each have a second overlapping portion.
