[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] With the continuous development of the automotive industry, people have increasingly higher requirements for the aesthetic appearance of car doors. As one of the most frequently used components by occupants, the door's appearance also faces greater demands. Current car doors typically consist of an outer panel, an inner panel, and structural components located between the outer and inner panels. These structural components are usually welded to the inner panel. This results in a large number of exposed weld points after the door is assembled, thus reducing its aesthetic appeal. Furthermore, the locations of these weld points vary, making it difficult to conceal them using trim panels or rubber strips.

[0041] In view of the above-mentioned technical problems, the first aspect of this utility model provides a car door, which can be referred to Figures 1 to 14 As shown, the car door includes an outer panel 1 and an inner panel 2, forming a receiving cavity 110 between the outer panel 1 and the inner panel 2; the car door also includes an upper hinge reinforcing plate 3, a door lock reinforcing plate 4 and an outer support plate 5 disposed in the receiving cavity 110; the upper hinge reinforcing plate 3 and the door lock reinforcing plate 4 are respectively located on both sides of the receiving cavity 110 and are both connected to the inner panel 2, and the two ends of the outer support plate 5 are respectively connected to the upper hinge reinforcing plate 3 and the door lock reinforcing plate 4, and the connection between the outer support plate 5 and the upper hinge reinforcing plate 3 and the door lock reinforcing plate 4 is located in the receiving cavity 110.

[0042] Through the above technical solution, namely the car door provided by this utility model, the car door changes the connection position of the outer support plate 5. That is, the door lock reinforcing plate 4 and the upper hinge reinforcing plate 3 are both located in the receiving cavity 110 between the outer plate 1 and the inner plate 2. The welding positions of the outer support plate 5 and the upper hinge reinforcing plate 3, as well as the welding positions of the outer support plate 5 and the door lock reinforcing plate 4, are all located in the receiving cavity 110. After the outer plate 1 and the inner plate 2 are fastened together, the welding points connecting the outer support plate 5 and the upper hinge reinforcing plate 3, as well as the welding points connecting the outer support plate 5 and the door lock reinforcing plate 4, will be covered by the outer plate 1 and the inner plate 2. This can reduce the number of welding points exposed on the outside of the outer plate 1 and / or the inner plate 2 of the car door, and improve the aesthetics of the car door.

[0043] It should be noted that in the above embodiments, the present invention mainly changes the connection position of the outer support plate 5. In related technologies, the two ends of the outer support plate 5 are usually directly welded to the inner panel 2 of the car door. After the outer panel 1 and inner panel 2 are fastened together, the weld points between the outer support plate 5 and the inner panel 2 are exposed outside the inner panel 2, thus affecting aesthetics. However, in the present invention, the outer support plate 5 is welded separately to the upper hinge reinforcing plate 3 and the door lock reinforcing plate 4 located within the receiving cavity 110; that is, the weld points after the three are welded are located inside the receiving cavity 110. Thus, after the outer panel 1 and inner panel 2 are fastened together, there is no situation where the weld points between the outer support plate 5 and the inner panel 2 are exposed, affecting aesthetics.

[0044] It can be understood that the main purpose of this utility model is to cover and hide the weld points between the outer support plate 5 and the inner plate 2 of the car door in order to improve the aesthetic performance of the car door.

[0045] Furthermore, by connecting the outer support plate 5 to the upper hinge reinforcement plate 3 and the door lock reinforcement plate 4 respectively, the impact resistance of the door in the upper hinge and door lock areas can be further improved. It can be understood that in related technologies, the upper hinge and door lock areas of a car door are typically areas with relatively weak impact resistance; therefore, it is usually necessary to separately install the upper hinge reinforcement plate 3 and the door lock reinforcement plate 4 to improve the impact resistance of these two areas. The connection method described above, where the outer support plate 5 is connected to the upper hinge reinforcement plate 3, further improves the impact resistance of the upper hinge area of ​​the car door. When the upper hinge area is subjected to external impact, the impact can be jointly borne by a part of the outer support plate 5 and the upper hinge reinforcement plate 3, thereby improving the structural strength of the upper hinge area. Similarly, the connection between the outer support plate 5 and the door lock reinforcement plate 4 can further improve the impact resistance of the door lock area. That is, when the door lock area is subjected to external impact, the impact can also be jointly borne by another part of the outer support plate 5 and the door lock reinforcement plate 4, thereby improving the structural strength of the door lock area.

[0046] It should be further clarified that the aforementioned outer panel 1 refers to the metal panel on the side of the door facing away from the passenger compartment, that is, the outermost protective panel on the side of the vehicle body. When the door is subjected to external impact, the outer panel 1 can provide initial protection as the outermost layer.

[0047] It should be further clarified that the aforementioned inner panel 2 refers to the metal panel on the side of the door facing the passenger compartment, which is the innermost protective panel on the side of the vehicle body. When the door is subjected to external impact, the inner panel 2 can act as the last line of protection to safeguard the safety of the occupants.

[0048] It should be further explained that the aforementioned outer support plate 5 refers to a long strip of metal that can be used to support the outer plate 1 between the outer plate 1 and the inner plate 2. That is to say, when the car door is subjected to external impact, the support of the outer support plate 5 on the outer plate 1 can further reduce the deformation of the outer plate 1 caused by the impact, so as to further improve the protection of the occupants on the inside of the car door.

[0049] To further explain the positional relationship between the upper hinge reinforcing plate 3 and the outer support plate 5 within the receiving cavity 110, please refer to... Figure 5 , Figure 6 , Figure 8 , Figure 11 , Figure 12 and Figure 14 As shown, the upper hinge reinforcing plate 3 has a first flange 310 at the end facing the outer plate 1. The first flange 310 is bent toward the middle of the receiving cavity 110 and is spaced apart from the outer plate 1. The first end of the outer support plate 5 is connected to the first flange 310.

[0050] By setting the aforementioned first flange 310, when the upper hinge reinforcing plate 3 is welded to the outer support plate 5, it can be connected to one end of the outer support plate 5 by bending the first flange 310 towards the center of the receiving cavity 110. Since the first flange 310 is located inside the receiving cavity 110, the connection between the first flange 310 and the outer support plate 5 is also located inside the receiving cavity 110, thus achieving the transfer of the connection between the two towards the inside of the receiving cavity 110. Figure 8 As shown, the first flange 310 bends toward the middle of the receiving cavity 110. Compared with the connection method in the related technology, by adding the first flange 310, the outer support plate 5 no longer needs to be welded to the inner panel 2 of the door, but is instead welded to the first flange 310 of the upper hinge reinforcing plate 3. The weld point is located inside the receiving cavity 110 and is covered by the outer panel 1 and the inner panel 2, which can hide the weld point and improve the aesthetics of the door.

[0051] It should be noted that the first flange 310 mentioned in the above embodiments can be made by rolling and bending the edge of the upper hinge reinforcing plate 3, or by integral casting of the mold, or any suitable manufacturing method. Furthermore, the specific shape of the first flange 310 can also be selected according to the actual layout of the interior of the car door. This embodiment does not make any specific limitation in this regard.

[0052] Based on the above embodiments, to further explain in detail the positional relationship between the door lock reinforcing plate 4 and the outer support plate 5 within the receiving cavity 110, please refer to... Figure 3 , Figure 4 , Figure 9 , Figure 11 , Figure 12 and Figure 13 As shown, the end of the door lock reinforcing plate 4 facing the outer plate 1 is provided with a second flange 410. The second flange 410 is bent toward the middle of the receiving cavity 110 and is spaced apart from the outer plate 1. The second end of the outer support plate 5 is connected to the second flange 410.

[0053] By providing the aforementioned second flange 410, when welding the door lock reinforcing plate 4 to the outer support plate 5, the second flange 410, bent towards the center of the receiving cavity 110, can be connected to the end of the outer support plate 5 away from the first flange 310. Since the second flange 410 is located within the receiving cavity 110, the connection point between the second flange 410 and the outer support plate 5 is also located within the receiving cavity 110, thus shifting the connection point towards the inside of the receiving cavity 110. Figure 9 As shown, the second flange 410 bends toward the middle of the receiving cavity 110. Compared with the connection method in the related technology, by adding the second flange 410, the other end of the outer support plate 5 no longer needs to be welded to the inner panel 2 of the door, but is instead welded to the second flange 410 of the door lock reinforcing plate 4. The welding point here is also located in the receiving cavity 110 and is covered by the outer panel 1 and the inner panel 2, which can hide the welding point and improve the aesthetics of the door.

[0054] Combination Figure 11 As can be seen, the first flange 310 and the second flange 410 are bent in the direction of each other.

[0055] It should be noted that the second flange 410 mentioned in the above embodiment can also be made by rolling and bending the edge of the door lock reinforcing plate 4, or by molding in one piece with a mold, or any suitable manufacturing method. Furthermore, the specific shape of the second flange 410 can be selected according to the actual layout of the interior of the car door, and this embodiment does not impose too many restrictions on this.

[0056] Furthermore, the bending angles of the first flange 310 and the second flange 410 mentioned in the above embodiments can be arbitrarily suitable. For example... Figure 8 , Figure 9 Figure 13 and Figure 14 As shown, the first flange 310 can be bent at 90° relative to the main body of the upper hinge reinforcement plate 3, or the bending angle relative to the main body of the upper hinge reinforcement plate 3 can be either obtuse or acute; similarly, the second flange 410 can also be bent at 90° relative to the main body of the door lock reinforcement plate 4, or the bending angle relative to the main body of the door lock reinforcement plate 4 can be either obtuse or acute.

[0057] In some implementations, reference Figures 3 to 6 , Figure 8 , Figure 9 as well as Figures 11 to 14 As shown, the outer support plate 5 is welded to the upper hinge reinforcement plate 3, and multiple welding points 510 are provided at intervals at the connection between the outer support plate 5 and the upper hinge reinforcement plate 3; and / or, the outer support plate 5 is welded to the door lock reinforcement plate 4, and multiple welding points 510 are provided at intervals at the connection between the outer support plate 5 and the door lock reinforcement plate 4.

[0058] In the above manner, when the outer support plate 5 is connected to the upper hinge reinforcement plate 3 and / or the door lock reinforcement plate 4 respectively, the connection stability with the upper hinge reinforcement plate 3 and / or the door lock reinforcement plate 4 can be improved by welding through multiple weld points 510. This can be referenced... Figure 11 As shown, when the outer support plate 5 is welded to the upper hinge reinforcement plate 3, the outer support plate 5 can be connected and fixed to the upper hinge reinforcement plate 3 through two spaced welding points 510 in the width direction; when the outer support plate 5 is welded to the door lock reinforcement plate 4, the outer support plate 5 can also be connected and fixed to the door lock reinforcement plate 4 through two spaced welding points 510 in the width direction.

[0059] It should be noted that, in the above embodiment, the number of weld points 510 where the outer support plate 5 is welded to the upper hinge reinforcing plate 3 and the door lock reinforcing plate 4 is two, which is exemplary. In other embodiments not shown in the figure, the number of weld points 510 between the outer support plate 5 and the upper hinge reinforcing plate 3 can also be other numbers, such as three, four or more. Similarly, the number of weld points 510 between the outer support plate 5 and the door lock reinforcing plate 4 can also be other numbers, such as three, four or more. This embodiment does not specifically limit this.

[0060] However, it should be noted that the welding points 510 mentioned in the above embodiments all need to be located inside the receiving cavity 110 and can be covered by the outer panel 1 and the inner panel 2, thereby hiding the welding points and improving the aesthetics of the door.

[0061] In some implementations, reference Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 11 and Figure 12 As shown, the outer support plate 5 is formed by bending a sheet material, and the thickness of the outer support plate 5 is in the range of 0.6cm to 0.8cm.

[0062] Through the above method, the outer support plate 5 is formed by bending sheet metal, which simplifies the manufacturing process and improves production efficiency during mass production. Furthermore, the thickness of the outer support plate 5, within the range of 0.6cm to 0.8cm, ensures good support for the outer panel 1 of the car door while also offering the advantage of lightweight design. It should be further noted that the thickness range of 0.6cm to 0.8cm means that after bending, the thickness of each cross-section of the outer support plate 5 remains within the range of 0.6cm and 0.8cm. Under this constraint, the thickness of the outer support plate 5 remains the same or similar in all areas, resulting in consistent overall structural strength and stable support for the outer panel 1. This also ensures consistent impact resistance throughout the outer support plate 5 when the outer panel 1 is deformed by external impact.

[0063] For example, the thickness of the outer support plate 5 can be selected as 0.6cm, 0.62cm, 0.64cm, 0.66cm, 0.68cm, 0.7cm, 0.72cm, 0.74cm, 0.76cm, 0.78cm or 0.8cm, or any value between two values, such as 0.615cm, which is between 0.6cm and 0.62cm.

[0064] Furthermore, the outer support plate mentioned in the above embodiments can be made of any material that can be easily bent and formed, such as carbon steel, aluminum, stainless steel, alloy and other metal materials. Specifically, the appropriate material can be selected for bending and forming based on the actual bending resistance and lightweight requirements of the outer support plate. This embodiment does not make specific limitations in this regard.

[0065] In some implementations, reference Figure 5 , Figure 11 and Figure 12 As shown, one side wall of the outer support plate 5 is attached to the outer plate 1; and / or, the outer support plate 5 is provided with a reinforcing protrusion 520.

[0066] In this way, one side wall of the outer support plate 5, when attached to the outer panel 1, provides good support for the outer panel 1. When the outer panel 1 of the vehicle door is impacted, the outer support plate 5, attached to the outer panel 1, also provides good impact resistance, thereby reducing the deformation of the outer panel 1 under impact and improving the safety of occupants located inside the vehicle door. Furthermore, to further improve the structural strength of the outer support plate 5 itself, such as... Figure 12 As shown, the reinforcing protrusions 520 on the outer support plate 5 can act as reinforcing ribs, thereby reducing the deformation of the outer support plate 5 when the outer panel 1 of the door is impacted, making it less prone to bending and deformation.

[0067] Furthermore, the number, shape, and orientation of the reinforcing protrusions 520 in the above embodiments can be arbitrarily suitable, such as... Figure 12 As shown, the number of reinforcing protrusions 520 can be multiple boss structures arranged at intervals along the length direction of the outer support plate 5, and... Figure 12 In the example, the lengths of the multiple boss structures along the length of the outer support plate 5 can also be different to meet the requirements of varying bending resistance at different locations along the length of the outer support plate 5. The orientation of the multiple reinforcing protrusions 520 is... Figure 12 In the example, all are facing away from the outer plate 1. In this arrangement, the outer support plate 5 can be kept as straight as possible in the direction facing the outer plate 1, so that it can be stably attached to the inner wall of the outer plate 1 to achieve a good support effect, and its own structural strength can be improved by multiple reinforcing protrusions 520 facing away from the outer plate 1.

[0068] In some implementations, reference Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 10 As shown, the door also includes a lower hinge reinforcement plate 6 and a crash beam 7. The lower hinge reinforcement plate 6 is connected to the inner panel 2 and located in the receiving cavity 110. The lower hinge reinforcement plate 6 and the upper hinge reinforcement plate 3 are located on the same side of the receiving cavity 110. The crash beam 7 is located in the receiving cavity 110. One end of the crash beam 7 is connected to the lower hinge reinforcement plate 6, and the other end is connected to the inner panel 2.

[0069] By connecting one end of the anti-collision beam 7 to the lower hinge reinforcement plate 6 in the above manner, both the lower part of the door can be protected against impact, and the structural reinforcement of the lower hinge area of ​​the door can be improved, thereby enhancing the impact resistance of the lower hinge area. (See reference...) Figure 3As shown, the lower hinge area of ​​the car door, like the upper hinge area mentioned in the above embodiments, is a relatively weak area in terms of impact resistance. Therefore, it needs to be reinforced by the lower hinge reinforcement plate 6. Furthermore, by connecting one end of the anti-collision beam 7 to the lower hinge reinforcement plate 6, the impact resistance of the lower hinge area of ​​the car door can be further improved. That is, when the lower hinge area of ​​the car door is subjected to external impact, the structural strength of the lower hinge area can be improved through the combined impact resistance of the anti-collision beam 7 and the lower hinge reinforcement plate 6.

[0070] In some implementations, reference Figure 7 and Figure 10 As shown, the lower hinge reinforcement plate 6 includes a third flange 610, which is bent toward the outside of the receiving cavity 110. The third flange 610 is connected to the anti-collision beam 7 and the inner plate 2.

[0071] The connection relationship between the anti-collision beam 7 and the lower hinge reinforcement plate 6 is further refined through the above method, that is, in Figure 10 In the example, one side of the anti-collision beam 7 is welded to the third flange 610 of the lower hinge reinforcement plate 6, thereby improving the impact resistance of the lower hinge area of ​​the door, and because the third flange 610 bends outward toward the receiving cavity 110. For example Figure 10 As shown, the third flange 610 of the lower hinge reinforcement plate 6 is sandwiched between the anti-collision beam 7 and the inner plate 2. The lower hinge area of ​​the door can be reinforced by the connection between the lower hinge reinforcement plate 6 and the anti-collision beam 7.

[0072] In some implementations, reference Figure 7 As shown, the anti-collision beam 7 is welded to the lower hinge reinforcing plate 6, and multiple welding points 510 are provided at intervals at the connection between the anti-collision beam 7 and the lower hinge reinforcing plate 6; and / or, the anti-collision beam 7 is welded to the inner plate 2, and multiple welding points 510 are provided at intervals at the connection between the anti-collision beam 7 and the inner plate 2.

[0073] In the above manner, one end of the anti-collision beam 7 can be welded to the lower hinge reinforcement plate 6 through multiple welding points 510, and the other end of the anti-collision beam 7 can be welded to the inner plate 2 through multiple welding points 510. The simultaneous connection through multiple welding points 510 further improves the stability of the connection between the anti-collision beam 7 and the lower hinge reinforcement plate 6 and the inner plate 2, thereby improving the impact resistance of the anti-collision beam 7 when the door is subjected to external impacts. It should be noted that the number of welding points 510 connecting the anti-collision beam 7 and the lower hinge reinforcement plate 6 can be the same as or different from the number of welding points 510 connecting the anti-collision beam 7 and the inner plate 2, and the number of welding points 510 can be arbitrarily suitable. For example, the number of welding points 510 connecting the anti-collision beam 7 and the inner plate 2 can be two, three, four, or more. The specific number can be selected according to the actual welding requirements, and this embodiment does not impose further limitations on this.

[0074] For example, in Figure 7 In the example, there can be four weld points between the anti-collision beam 7 and the lower hinge reinforcement plate 6. At the other end of the anti-collision beam 7, there can be six weld points between the anti-collision beam 7 and the inner panel 2 of the door. Furthermore, the multiple weld points connecting the anti-collision beam 7 and the lower hinge reinforcement plate 6 can be arranged at intervals. Similarly, the weld points between the anti-collision beam 7 and the inner panel 2 of the door can also be arranged at intervals. The specific number and arrangement of weld points can be selected based on the specific structure of the anti-collision beam 7, the lower hinge reinforcement plate 6, and the inner panel 2. This embodiment does not impose specific limitations on this.

[0075] A second aspect of this utility model provides a vehicle that includes the door mentioned in the above embodiments and has all the beneficial effects of the specific embodiments described above. The vehicle can be a gasoline-powered car, gasoline-powered truck, etc., in the field of gasoline vehicles; or it can be a pure electric vehicle, plug-in hybrid electric vehicle, or range-extended vehicle, etc., in the field of new energy vehicles. Specifically, it can be any suitable model such as a sedan, SUV, or MPV. Furthermore, the aforementioned door can be applied to the door structure of any of the aforementioned vehicle models; for example, the door can be applied to the driver's side door, passenger side door, or rear door of the vehicle. This embodiment does not impose excessive limitations on this.

[0076] The present invention exemplarily describes the overall beneficial effects of the car door, as detailed below.

[0077] One end of the outer support plate 5 is connected to the first flange 310 of the upper hinge reinforcement plate 3, and the other end is connected to the second flange 410 of the door lock reinforcement plate 4. By connecting to the upper hinge reinforcement plate 3 and the door lock reinforcement plate 4 respectively, the upper hinge area and the door lock area of ​​the car door, which have relatively weak impact resistance, are reinforced by the connection of the outer support plate 5 to improve the impact resistance of these two areas. The first flange 310 and the second flange 410 are both bent towards the middle of the receiving cavity 110. When the outer support plate 5 is welded to the first flange 310 and the second flange 410 respectively, and when the outer plate 1 and the inner plate 2 are fastened together, the weld points 510 connecting the outer support plate 5 to the first flange 310 and the weld points connecting the outer support plate 5 to the second flange 410 will be housed in the receiving cavity 110 and covered by the outer plate 1 and the inner plate 2, thereby reducing the exposure of the weld points and improving the aesthetics of the car door.

[0078] Furthermore, by connecting the anti-collision beam 7 with the lower hinge reinforcement plate 6, the lower hinge area of ​​the door can be reinforced by the anti-collision beam 7 to improve the impact resistance of the lower hinge area.

[0079] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
