[0002] In modern automotive design, the rigidity and sag rigidity of car doors are crucial to the overall performance of the vehicle. Traditional door outer panel support panels typically employ a single planar structure. This design is prone to decreased rigidity and sag after prolonged use, affecting the vehicle's appearance, safety, and ride comfort. Furthermore, while increasing panel width or thickness is a common approach to enhance door rigidity, this not only increases vehicle weight and manufacturing costs but also fails to fundamentally address the insufficient rigidity issue. Additionally, some designs incorporate anti-collision beams connected to the inner door panel, with at least two hollow cavities to disperse and absorb external impacts. However, the connection and support between the anti-collision beam and the outer door panel cannot be guaranteed, thus affecting the door's durability and safety, indicating room for improvement.

[0024] The following is for reference. Figures 1-5According to the embodiment of the present utility model, the inner door panel assembly 100 can provide sufficient support for the inner door panel 1 by providing an outer panel support beam 2 with a reinforcing cavity 21, and the outer panel support plate 22 can provide sufficient support for the outer panel support beam 2 and the outer door panel, thereby satisfying the rigidity and overall anti-sagging ability of the outer door panel and effectively improving the durability and safety of the door.

[0025] like Figures 1-5 As shown, a door inner panel assembly 100 according to an embodiment of the present invention includes: a door inner panel 1 and an outer panel support beam 2.

[0026] The inner panel of the car door 1; the outer panel support beam 2, the outer panel support beam 2 is connected to the outer side of the inner panel of the car door 1 and is adapted to support the inner side of the outer panel of the car door; wherein, the outer panel support beam 2 is constructed as a hollow beam and forms a reinforcing cavity 21, and the outer panel support beam 2 is connected and supported to the outer panel of the car door through at least one outer panel support plate 22.

[0027] Specifically, the inner door panel assembly 100 is the main structure of the door, providing overall rigidity and resistance to deformation. In side collisions or rollover accidents, it effectively disperses impact forces, reduces door deformation, and protects the safety of passengers inside the vehicle. Furthermore, the inner door panel 1 can integrate the installation of core components such as locks, hinges, window regulators, and wiring harnesses, ensuring the stable operation of each system and meeting the performance and user experience requirements of the door.

[0028] The inner door panel 1 is located on the inner side of the door and serves as the door's skeletal structure, maintaining its structural strength and rigidity. The outer panel support beam 2 provides support and reinforcement. Connecting the outer panel support beam 2 to the outer side of the inner door panel 1 allows it to structurally reinforce the inner door panel 1 from the outside. Furthermore, the outer panel support beam 2 can also support the inner side of the outer door panel, thus structurally reinforcing it from the inside. By connecting the outer panel support beam 2 to both the inner and outer sides of the door panel 1, and vice versa, the outer panel support beam 2 effectively connects the inner and outer door panels, reinforcing the overall structure of both panels and enhancing the overall structural strength of the door.

[0029] It should also be noted that the outer panel support beam 2 can be connected to the outer side of the inner panel 1 of the car door by means of bolts, welding, glue, etc., and the outer panel support beam 2 can be connected to the outer panel of the car door by means of bolts, welding, glue, etc.

[0030] Among them, the outer plate support beam 2 is a hollow beam, that is, as shown in the figure. Figure 5As shown, the outer panel support beam 2 has a hollow cavity inside, which can form a reinforcing cavity 21. The reinforcing cavity 21 enhances the structural strength of the outer panel support beam 2. In practical use, the outer panel support beam 2 provides a force transmission path between the inner door panel 1 and the outer door panel. That is, the reinforcing cavity 21 enables force transmission and absorption, thereby improving the structural stability and durability of the outer panel support beam 2, and consequently improving the structural stability and durability of the inner door panel assembly 100. Furthermore, the reinforcing cavity 21 is a hollow cavity; compared to a solid structure, the hollow structure can effectively reduce the structural weight of the outer panel support beam 2, reducing the overall weight of the inner door panel assembly 100, meeting the requirements for lightweight design, and reducing vehicle energy consumption. Additionally, the outer panel support beam 2 can be made of 6082 aluminum alloy, which has reliable structural strength and can reduce vehicle weight and energy consumption. The outer panel support beam 2 can also be made of materials such as steel plates.

[0031] Furthermore, the outer panel support beam 2 is connected and supported to the outer panel of the car door through at least one outer panel support plate 22. That is, the outer panel support beam 2 can be connected to the outer panel of the car door through one outer panel support plate 22, or the outer panel support plate 22 can be connected to the outer panel of the car door through two or more outer panel support plates 22. Both of the above different settings can achieve the outer panel support beam 2 supporting the outer panel of the car door. The settings are diverse and can be set according to the actual installation strength and requirements.

[0032] In other words, the outer panel support plate 22 can be disposed between the outer panel support beam 2 and the outer door panel, that is, the outer panel support plate 22 can be connected to the outer panel support beam 2, and the outer panel support beam 2 is also connected to the outer door panel. Through the outer panel support plate 22, the outer panel support beam 2 and the outer door panel can be connected, and the outer panel support beam 2 is located on the inner side of the outer door panel, that is, the outer panel support plate 22 can be connected to the inner side of the outer door panel. This allows the outer panel support plate 22 to structurally reinforce the outer door panel on the inner side of the outer door panel. In this way, the outer panel support plate 22 can not only connect the outer panel support beam 2 and the outer door panel, but also support and strengthen the structure of the outer door panel to improve the overall rigidity of the outer door panel.

[0033] Thus, during vehicle operation, the door will be subjected to certain external forces. The door inner panel assembly 100 of this application has sufficient structural strength to effectively disperse and absorb external impact forces, thereby improving the structural stability and reliability of the door, as well as enhancing the overall durability and safety of the door.

[0034] Traditional door outer panel support beams 2 often employ a single planar structure. A single planar structure cannot provide sufficient support and stability. The conventional approach is to increase the width or thickness of the panel, but this not only increases the vehicle's weight and manufacturing cost but also fails to fundamentally solve the problem of insufficient rigidity. Furthermore, planar support plates cannot effectively disperse and absorb external impact forces. In contrast, the outer panel support beam 2 of this application is constructed as a hollow beam with a reinforcing cavity 21 inside. This enhances the structural strength of the outer panel support beam 2, providing sufficient support for the inner door panel 1. Furthermore, the outer panel support plate 22 connects the outer panel support beam 2 to the outer door panel, providing sufficient support for the outer door panel. This fundamentally solves the problem of insufficient door rigidity and effectively improves the door's impact resistance and stability.

[0035] According to the embodiment of the present utility model, the door inner panel assembly 100 is configured with an outer panel support beam 2 as a hollow beam, which has a reinforcing cavity 21 inside, forming a box structure to improve the structural strength of the outer panel support beam 2. The outer panel support beam 2 can provide sufficient support for the door inner panel 1, and the outer panel support plate 22 connects the outer panel support beam 2 and the door outer panel to provide sufficient support for the door outer panel. This satisfies the rigidity and overall anti-sagging ability of the door outer panel, effectively improving the durability and safety of the door, and enhancing the appearance quality and ride comfort of the vehicle. At the same time, the hollow beam configuration maintains the lightweight design of the vehicle body, reduces vehicle energy consumption, and enhances practicality.

[0036] In some embodiments, multiple outer panel support plates 22 are provided, and the multiple outer panel support plates 22 are spaced apart along the length direction of the outer panel support beam 2. That is, the multiple outer panel support plates 22 can be connected to multiple positions along the length direction of the outer panel support beam 2, and the outer panel support plates 22 are connected to the outer panel of the car door. In other words, the multiple outer panel support plates 22 can be connected to multiple positions along the outer panel of the car door. In this way, the outer panel support beam 2 can be connected to the outer panel of the car door at multiple positions along its length direction through the multiple outer panel support plates 22, which can improve the connection strength and stability between the outer panel support beam 2 and the outer panel of the car door. Furthermore, the outer panel support beam 2 is connected to the inner panel of the car door 1, which can effectively improve the overall structural strength of the inner panel of the car door 1 and the outer panel of the car door, so as to meet the rigidity and overall anti-sagging ability of the car door.

[0037] Specifically, the outer panel support plates 22 can be set to two, three, four, five, six, seven, eight, etc. Among them, multiple outer panel support plates 22 can be evenly spaced along the length direction of the outer panel support beam 2, so that the spacing between two adjacent outer panel support plates 22 is the same or closer. In this way, multiple outer panel support plates 22 are connected to multiple evenly spaced positions of the car door outer panel, which improves the support stability and reliability of the multiple outer panel support plates 22 for the car door outer panel, thereby improving the connection strength and stability between the outer panel support beam 2 and the car door outer panel.

[0038] In other embodiments, the outer plate support plate 22 is configured as two sets, with the two sets of outer plate support plates 22 spaced apart along the width direction of the outer plate support beam 2, i.e. Figure 2 As shown, the two sets of outer panel support plates 22 can be connected to two positions in the width direction of the outer panel support beam 2, and the outer panel support plates 22 are connected to the outer panel of the car door. This allows the outer panel support beam 2 to be connected to two areas of the outer panel of the car door in its width direction through the two sets of outer panel support plates 22, which can improve the connection strength and stability between the outer panel support beam 2 and the outer panel of the car door. Furthermore, the outer panel support beam 2 is connected to the inner panel 1 of the car door, which can effectively improve the overall structural strength of the inner panel 1 and the outer panel of the car door, thereby improving the rigidity of the car door and its overall anti-sagging ability.

[0039] Specifically, the two sets of outer plate support plates 22 can be distributed on both sides of the width direction of the outer plate support beam 2, or the two sets of outer plate support plates 22 can be distributed at two positions in the width direction of the outer plate support beam 2. The arrangement can be selected according to the actual space and installation requirements. In addition, multiple sets of outer plate support plates 22 can be set.

[0040] In some embodiments, the outer support plate 22 includes a first connecting plate 221 and a second connecting plate 222 that are bent and connected together.

[0041] Specifically, such as Figure 3 As shown, the first connecting plate 221 and the second connecting plate 222 are bent and connected, so that the planes on which the first connecting plate 221 and the second connecting plate 222 are distributed are different. This facilitates the connection of the outer panel support plate 22 with the outer panel support beam 2 and the outer door panel through the first connecting plate 221 and the second connecting plate 222, increasing the possibility of assembling the outer panel support plate 22 with the outer panel support beam 2 and the outer door panel at different angles. The bending angle of the first connecting plate 221 and the second connecting plate 222 can be a right angle or a non-right angle; the setting method is not limited and can be set according to actual space requirements. In this embodiment, the first connecting plate 221 and the second connecting plate 222 are connected perpendicularly, that is, the outer panel support plate 22 can be constructed as an "L" shaped structure.

[0042] Among them, such as Figure 3As shown, the first connecting plate 221 is fitted and connected to the side wall of the outer panel support beam 2 in the width direction, thereby connecting the first connecting plate 221 to the outer panel support beam 2, and thus connecting the outer panel support plate 22 to the outer panel support beam 2. Furthermore, the first connecting plate 221 is connected to the side wall of the outer panel support beam 2 in the width direction, which reduces the size of the first connecting plate 221 protruding from the outer panel support beam 2 near the door outer panel, making the connection between the outer panel support plate 22 and the outer panel support beam 2 more compact. The sidewalls of the outer panel support beam 2 are fitted together in the width direction, which can improve the connection tightness and stability between the first connecting plate 221 and the outer panel support beam 2. The second connecting plate 222 is used to fit and connect with the outer panel of the car door. The outer panel support plate 22 is connected to the outer panel of the car door through the second connecting plate 222. The connection tightness and stability between the second connecting plate 222 and the outer panel of the car door can be improved. In this way, the connection stability between the outer panel support plate 22 and the outer panel of the car door can be improved, thereby improving the connection stability between the outer panel support beam 2 and the outer panel of the car door.

[0043] The first connecting plate 221 can be connected to the side wall of the outer panel support beam 2 in the width direction using FDS (Flow Drill Screw) technology. Compared with traditional welding or screwing methods, FDS technology exhibits superior material compatibility, sealing performance, and strength, improving the tightness of the connection between the first connecting plate 221 and the outer panel support beam 2, while also facilitating disassembly and maintenance. Furthermore, the second connecting plate 222 can be connected to the outer door panel using shock-absorbing expansion adhesive, further enhancing the rigidity of the outer door panel and the overall rigidity of the door in the Z-axis direction, and improving the shock absorption effect between the outer door panel and the inner door panel 1.

[0044] In some embodiments, each group of outer plate support plates 22 includes multiple outer plate support plates 22; wherein, the multiple outer plate support plates 22 of each group are distributed one-to-one along the width direction of the outer plate support beam 2, or the multiple outer plate support plates 22 of each group are staggered along the width direction of the outer plate support beam 2. That is to say, in actual design, one of the above methods can be selected to achieve a reasonable arrangement of the multiple outer plate support plates 22 of each group in the width direction of the outer plate support beam 2. The arrangement is diverse and can be flexibly selected.

[0045] Specifically, multiple outer panel support plates 22 in each group are distributed one-to-one along the width direction of the outer panel support beam 2. That is, the multiple outer panel support plates 22 in each group can be symmetrically distributed along the width direction of the outer panel support beam 2. In this way, the two groups of outer panel support plates 22 are symmetrically distributed on the width of the outer panel support beam 2, which can improve the uniformity of force between the two groups of outer panel support plates 22, the outer panel support beam 2, and the outer panel of the door, thereby improving the connection stability between the two groups of outer panel support plates 22, the outer panel support beam 2, and the outer panel of the door. Alternatively, multiple outer panel support plates 22 in each group can be staggered along the width direction of the outer panel support beam 2. That is, multiple outer panel support plates 22 in one group and multiple outer panel support plates 22 in another group are staggered in sequence. The multiple outer panel support plates 22 in both groups are connected between the outer panel support beam 2 and the outer panel of the door. This allows the multiple connection positions between the multiple outer panel support plates 22 in one group and the outer panel of the door to be staggered in sequence, thereby improving the uniformity and stability of the connection between the multiple outer panel support plates 22 in both groups and different areas of the outer panel of the door.

[0046] In this embodiment, as Figure 2 As shown, each group has five outer plate support plates 22, and the number of outer plate support plates 22 is not limited to five. It can be selected and set according to the actual length of the outer plate support beam 2.

[0047] In some embodiments, the outer plate support beam 2 extends in the front-to-back direction.

[0048] Specifically, the outer panel support beam 2 has a cuboid structure. By extending along the front-rear direction, the outer panel support beam 2 can transmit force in that direction. Furthermore, the outer panel support beam 2 connects the inner door panel 1 and the outer door panel, allowing it to transmit force from either the inner or outer door panel in the front-rear direction. The outer panel support beam 2 also boasts high structural strength, enhancing the effectiveness and stability of force transmission between the inner and outer door panels. The outer panel support beam 2 can extend either along the front-rear direction or at an angle to the front-rear direction; its configuration is flexible and can be chosen flexibly.

[0049] The outer panel support beam 2 is connected at its front end to the front side of the inner door panel 1 and at its rear end to the rear side of the inner door panel 1 via the rear support frame 23. This means that in the longitudinal direction of the vehicle, as shown... Figure 1 As shown, the front end of the outer panel support beam 2 is directly connected to the front side of the inner door panel 1, and the rear end of the outer panel support beam 2 is connected to the rear side of the inner door panel 1 through the rear support frame 23. This enables the connection and fixation between the outer panel support beam 2 and the inner door panel 1, and allows the outer panel support beam 2 to span the front and rear of the inner door panel 1. This enhances the structural reinforcement strength of the outer panel support beam 2 on the inner door panel 1 in the front and rear areas, and also enhances the structural reinforcement strength of the outer panel support beam 2 on the outer door panel in the front and rear areas.

[0050] Furthermore, the front end of the outer panel support beam 2 can be detachably connected to the inner door panel 1 via bolts or other fasteners, and the rear end of the outer panel support frame can be connected to the inner door panel 1 via bolts, welding, or other means.

[0051] In some embodiments, the rear support frame 23 is formed with a receiving groove 231, and at least part of the rear end of the outer plate support beam 2 extends into the receiving groove 231. The outer plate support beam 2 is connected to the inner sidewall of the receiving groove 231. In this way, at least part of the rear end of the outer plate support beam 2 can be inserted and engaged with the rear support frame 23 in the front-rear direction through the receiving groove 231, which can increase the engagement area between the outer plate support beam 2 and the rear support frame 23 in the front-rear direction and improve the connection strength between the outer plate support beam 2 and the rear support frame 23.

[0052] Specifically, the rear support frame 23 can form a receiving groove 231 that opens to the front, so that part of the rear end structure of the outer plate support beam 2 can extend into the receiving groove 231 in the front-back direction, and then connect the outer plate support beam 2 to the receiving groove 231, thereby improving the connection strength and reliability between the two. In this way, by setting the receiving groove 231, it is convenient to connect and disassemble the outer plate support beam 2 and the rear support frame 23.

[0053] In some embodiments, the rear support frame 23 includes a first support plate 232, a second support plate 233, a third support plate 234, and a fourth support plate 235. The first support plate 232 and the second support plate 233 are spaced apart in the inward and outward directions. The first support plate 232, the second support plate 233, the third support plate 234, and the fourth support plate 235 together define a receiving groove 231. The first support plate 232 and the second support plate 233 are respectively attached to the outer panel support beam 2, and the fourth support plate 235 is connected to the inner panel 1 of the door.

[0054] Specifically, the first support plate 232 and the second support plate 233 are spaced apart in the inward and outward directions, so that a certain gap is formed between the first support plate 232 and the second support plate 233, so that the receiving groove 231 can be located between the first support plate 232 and the second support plate 233, and as... Figure 4 As shown, the first support plate 232, the second support plate 233, the third support plate 234, and the fourth support plate 235 together define the receiving groove 231. That is, the first support plate 232, the second support plate 233, the third support plate 234, and the fourth support plate 235 can form the inner sidewall of the receiving groove 231. In this way, at least a portion of the structure at the rear end of the outer plate support beam 2 can be connected to at least one of the first support plate 232, the second support plate 233, the third support plate 234, and the fourth support plate 235 after extending into the receiving groove 231.

[0055] Furthermore, the first support plate 232 and the second support plate 233 are respectively used to be attached and connected to the outer plate support beam 2. That is, by connecting the two support plates to the outer plate support beam 2, the connection strength between the outer plate support beam 2 and the rear support frame 23 can be improved. Moreover, the first support plate 232 and the second support plate 233 are respectively attached and connected to the outer plate support beam 2, which can increase the connection area between the first support plate 232 and the second support plate 233 and the outer plate support beam 2, further improving the connection strength between the outer plate support beam 2 and the rear support frame 23. The first support plate 232 and the second support plate 233 are distributed at intervals along the inside and outside direction, and the outer side and the inner side of the outer plate support beam 2 can be connected to the first support plate 232 and the second support plate 233 respectively.

[0056] The first support plate 232 and the second support plate 233 can be connected to the outer and inner sides of the outer plate support beam 2 respectively through FDS flow drill screw technology. Compared with traditional welding or screwing methods, FDS technology exhibits better material compatibility, sealing performance and strength, which can improve the connection tightness between the first support plate 232 and the second support plate 233 and the outer plate support beam 2, while facilitating disassembly and maintenance.

[0057] Furthermore, the fourth support plate 235 is connected to the inner door panel 1, meaning that the rear support frame 23 can be connected to the inner door panel 1 via the fourth support plate 235, thus achieving the connection between the rear support frame 23 and the inner door panel 1. The fourth support plate 235 can also be connected to the inner door panel 1 by welding or other methods, ensuring the connection strength between the rear support frame 23 and the inner door panel 1, thereby ensuring the reliability of the connection between the outer panel support beam 2 and the inner door panel 1.

[0058] The third support plate 234 is connected between the first support plate 232 and the second support plate 233, and the fourth support plate 235 is connected to the rear edge of the third support plate 234. The first support plate 232, the second support plate 233 and the fourth support plate 235 are all located on the same side of the third support plate 234.

[0059] Specifically, the inner and outer sides of the third support plate 234 are connected to the first support plate 232 and the second support plate 233 respectively, allowing the first support plate 232 and the second support plate 233 to connect. The third support plate 234 can support the first support plate 232 and the second support plate 233 mutually, improving the connection strength between the third support plate 234, the first support plate 232, and the second support plate 233. The fourth support plate 235 is connected to the rear edge of the third support plate 234, and the fourth support plate 235 can be bent and connected to the rear edge of the third support plate 234. Figure 4As shown, the first support plate 232, the second support plate 233, and the fourth support plate 235 are all connected to the same side of the third support plate 234. The inner and outer sides of the fourth support plate 235 are connected to the first support plate 232 and the second support plate 233, respectively. This allows the first support plate 232, the second support plate 233, the third support plate 234, and the fourth support plate 235 to jointly define the receiving groove 231. The entire structure is similar to a box structure, making the structure of the first support plate 232, the second support plate 233, the third support plate 234, and the fourth support plate 235 more stable. Compared with the conventional planar design, this significantly improves the structural strength and stability of the rear support frame 23. Furthermore, the rear support frame 23 is connected to the rear ends of the inner door panel 1 and the outer panel support beam 2, respectively, which can improve the connection strength between the rear end of the outer panel support beam 2 and the inner door panel 1.

[0060] The length of the fourth support plate 235 can be greater than the length of the first support plate 232 and the second support plate 233, so as to facilitate the connection between the fourth support plate 235 and the inner panel 1 of the door. The inner and outer sides of the fourth support plate 235 can be connected to the first support plate 232 and the second support plate 233 respectively by welding, which can ensure the connection strength between the first support plate 232 and the second support plate 233 and the fourth support plate 235.

[0061] In some embodiments, at least one reinforcing rib 211 is provided in the reinforcing cavity 21, and the at least one reinforcing rib 211 is supported and connected to the inner wall of the reinforcing cavity 21 in the inward and outward directions.

[0062] Specifically, the reinforcing rib 211 serves to strengthen the structure. Placing at least one reinforcing rib 211 within the reinforcing cavity 21 enhances the overall strength of the cavity. The reinforcing rib 211 can be one, two, three, four, etc. At least one reinforcing rib 211 can be positioned to support the inner wall of the reinforcing cavity 21 along the inward and outward directions, thus supporting the inner wall of the cavity and improving the structural strength of the outer plate support beam 2. The inward and outward directions refer to the lateral direction of the vehicle, i.e., the Y-direction, with the inward direction being closer to the vehicle's centerline and the outward direction being farther from the centerline. This means that at least one reinforcing rib 211 can extend laterally along the vehicle, with both ends of the rib supporting the inner wall of the cavity 21, allowing for the arrangement and connection of the reinforcing ribs 211 within the cavity 21.

[0063] Thus, by providing at least one reinforcing rib 211 to support and connect to the inner wall of the reinforcing cavity 21 in the inward and outward directions, the reinforcing rib 211 can support the inner wall of the reinforcing cavity 21 in the inward and outward directions, thereby improving the structural strength of the outer panel support beam 2 in the inward and outward directions. Furthermore, the outer panel support beam 2 is connected to the inner side of the car door outer panel, which can improve the support strength of the outer panel support beam 2 on the inner side of the car door outer panel, thereby improving the structural strength of the car door outer panel and the car door inner panel 1 in the inward and outward directions, so as to meet the rigidity and overall anti-sagging ability of the car door outer panel, and thus enable the car door outer panel and the car door inner panel 1 to effectively disperse and absorb the impact force from the outside.

[0064] At least one reinforcing rib 211 divides the reinforcing cavity 21 into at least two reinforcing sub-cavities 212. That is, by connecting at least one reinforcing rib 211 to the inner wall of the reinforcing cavity 21, the reinforcing cavity 21 can be divided into at least two reinforcing sub-cavities 212, thus giving the outer plate support beam 2 at least two reinforcing sub-cavities 212, thereby improving the structural stability of the outer plate support beam 2. The reinforcing cavity 21 can extend along the length direction of the outer plate support beam 2, and the reinforcing sub-cavities 212 can also extend along the length direction of the outer plate support beam 2, so that external forces at the outer plate support beam 2 can be transmitted along the extension directions of the multiple reinforcing sub-cavities 212.

[0065] In this embodiment, the reinforcing cavity 21 is constructed as a square cavity, facilitating the support connection between the reinforcing ribs 211 and the inner wall of the reinforcing cavity 21, thereby ensuring the support stability of the reinforcing ribs 211 and the reinforcing cavity 21. Furthermore, the number of reinforcing sub-cavities 212 corresponds to the number of reinforcing ribs 211. In this embodiment, for example... Figure 5 As shown, there are two reinforcing ribs 211 in the square cavity and three reinforcing sub-cavities 212. Furthermore, the reinforcing ribs 211 can be constructed as strip ribs, which is simple in structure and easy to process.

[0066] In some embodiments, there are multiple reinforcing ribs 211, which are spaced apart and distributed in the reinforcing cavity 21 along the width direction of the outer plate support beam 2.

[0067] Specifically, multiple reinforcing ribs 211 are provided within the reinforcing cavity 21, which effectively enhances the overall strength of the reinforcing cavity 21. These reinforcing ribs 211 are spaced apart along the width direction of the outer panel support beam 2 within the reinforcing cavity 21. They are connected to the inner wall of the reinforcing cavity 21 at intervals along the inward and outward directions, providing support to the inner wall of the reinforcing cavity 21 in both directions. Furthermore, the multiple reinforcing ribs 211 support the inner wall of the reinforcing cavity 21 at multiple locations along the width direction of the outer panel support beam 2, thereby enhancing the structural strength of the outer panel support beam 2 at multiple locations along its width direction. Since the outer panel support beam 2 is connected to the inner side of the door outer panel, this enhances the support strength of the outer panel support beam 2 on the inner side of the door outer panel, thus improving the structural strength of both the door outer panel and the door inner panel 1 in both the inward and outward directions.

[0068] In some embodiments, the door inner panel assembly 100 further includes a crash beam 3 and a crash beam bracket 31. The crash beam 3 and the outer panel support beam 2 are vertically spaced apart between the door inner panel 1 and the door outer panel. The crash beam 3 and the outer panel support beam 2 are both configured to extend downward from front to back. The crash beam bracket 31 is located below the crash beam 3 and extends upward from front to back. The front end of the crash beam bracket 31 is connected to the door inner panel 1, and the rear end of the crash beam bracket 31 is connected to the middle of the crash beam 3.

[0069] Specifically, the crash beam 3 serves to connect, support, and resist external forces. For example... Figure 1 As shown, the anti-collision beam 3 and the outer panel support beam 2 are distributed vertically between the inner door panel 1 and the outer door panel, that is, the anti-collision beam 3 and the outer panel support beam 2 can respectively strengthen the vertical structure of the inner door panel 1 and the outer door panel.

[0070] Furthermore, the outer panel support beam 2 extends downward from front to back, and the anti-collision beam 3 extends downward from front to back. That is, the outer panel support beam 2 and the anti-collision beam 3 can respectively strengthen the structure of the inner panel 1 and the outer panel of the door in the front-rear direction and the structure of the lower rear area. Both the outer panel support beam 2 and the anti-collision beam 3 are set to extend downward from front to back, so that there will be no interference between the outer panel support beam 2 and the anti-collision beam 3. The outer panel support beam 2 and the anti-collision beam 3 can be distributed in parallel or not in parallel.

[0071] The anti-collision beam 3 extends downwards from front to back, leaving space in the lower front area of ​​the anti-collision beam 3 so that the anti-collision beam bracket 31 can be located below the anti-collision beam 3. Specifically, the anti-collision beam bracket 31 can be configured to extend upwards from front to back, with the front end of the anti-collision beam bracket 31 connected to the front side of the inner door panel 1 and the rear end connected to the middle of the anti-collision beam 3. In this way, the middle area of ​​the anti-collision beam 3 can be reinforced by the anti-collision beam bracket 31, and the inner door panel 1 can form two triangles, both of which are almost isosceles triangles. This makes the structure of the anti-collision beam bracket 31, the anti-collision beam 3, and the inner door panel 1 more stable.

[0072] Furthermore, the anti-collision beam bracket 31 extends upwards from front to back, so that the rear side of the anti-collision beam bracket 31 is close to the anti-collision beam 3, facilitating the connection and fixation between the two. The front side of the anti-collision beam 3 is close to the lower front area of ​​the door inner panel 1 and the hinge reinforcement plate, facilitating the connection of the front side of the anti-collision beam 3 to the door inner panel 1 and the hinge reinforcement plate. The outer side of the anti-collision beam bracket 31 can be fitted and connected to the door outer panel. The anti-collision beam bracket 31 can be constructed as a straight plate structure or as an arc-shaped plate structure.

[0073] Meanwhile, the rear side of the anti-collision beam bracket 31 can be connected to the anti-collision beam 3 by means of rivets, bolts, etc., and the front side of the anti-collision beam 3 can be connected to the inner door panel 1 and the hinge reinforcement plate by welding. The outer side of the anti-collision beam bracket 3 can be connected to the outer door panel by means of shock-absorbing rubber. In this way, the connection between the anti-collision beam bracket 31 and the outer door panel can be realized, and the shock absorption effect can be achieved.

[0074] Thus, the anti-collision beam bracket 31 can strengthen the central area of ​​the anti-collision beam 3, and the two triangular structures formed can effectively improve the structural stability of the anti-collision beam bracket 31, the anti-collision beam 3, and the inner door panel 1. Furthermore, the anti-collision beam bracket 31 is connected to the outer door panel, which can improve the structural strength and stability of the anti-collision beam 3, the inner door panel 1, and the outer door panel in the lower front area, further enhancing the rigidity and overall anti-sagging ability of the outer door panel. It can effectively disperse and absorb external impact forces, thereby improving the overall durability and safety of the door.

[0075] This utility model also proposes a vehicle.

[0076] The vehicle according to the present invention includes an outer door panel and an inner door panel assembly 100 of any of the above embodiments, wherein the outer door panel is connected to the outside of the inner door panel 1.

[0077] Specifically, the outer door panel is the external structure of the vehicle door. The outer door panel is located on the outer side of the door and is connected to the outer side of the inner door panel 1. That is, the outer door panel and the inner door panel 1 are distributed along the lateral direction of the vehicle, with the outer door panel distributed away from the center line of the vehicle and the inner door panel 1 distributed closer to the center line. The connection between the outer door panel and the inner door panel 1 allows them to support each other, which can improve the overall structural strength of the door and keep the external structure of the door flat.

[0078] Furthermore, by setting the outer panel support beam 2 as a hollow beam with a reinforcing cavity 21 inside, the structural strength of the outer panel support beam 2 can be improved, providing sufficient support for the inner panel 1 of the door. The outer panel support plate 22 connects the outer panel support beam 2 and the outer panel of the door, providing sufficient support for the outer panel of the door. This satisfies the rigidity and overall anti-sagging ability of the outer panel of the door, effectively improving the durability and safety of the door, enhancing the appearance quality and ride comfort of the vehicle. At the same time, the hollow beam design maintains the lightweight design of the vehicle body, reducing vehicle energy consumption and increasing practicality.
