[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0032] Limited by the structural strength of the door anti-collision beam, the improvement of the vehicle's side impact performance by the door anti-collision beam is relatively limited. In the event of a side collision, the door, including the door anti-collision beam, is still prone to significant deformation and intrusion into the passenger compartment, thereby causing injury to the occupants.

[0033] Based on this, the present invention provides a door anti-collision beam, a door inner panel assembly, a door, and a vehicle. The door anti-collision beam includes a door anti-collision beam body, which is connected to the door inner panel of the vehicle. The door anti-collision beam body and the door inner panel enclose a buffer cavity, thereby buffering and transmitting the collision force during a side collision to prevent the collision from intruding into the passenger compartment and causing injury to the occupants. Simultaneously, along the width direction of the door anti-collision beam body, a reinforcing structure is provided at least at one end of the door anti-collision beam body, located on the side of the door anti-collision beam body away from the door inner panel. This improves the structural strength and load-bearing capacity of the door anti-collision beam, thereby enhancing its anti-collision effect and improving the vehicle's collision safety performance. Furthermore, placing the reinforcing structure on the side of the door anti-collision beam body away from the door inner panel avoids affecting the sealing of the buffer cavity formed between the door anti-collision beam body and the door inner panel.

[0034] The following detailed description, with reference to the accompanying drawings and specific embodiments, illustrates the door anti-collision beam, door inner panel assembly, door, and vehicle provided by this utility model:

[0035] Reference Figures 1 to 3 As shown, this embodiment provides a door anti-collision beam, including a door anti-collision beam body 1.

[0036] The door anti-collision beam body 1 is used to connect to the inner panel 2 of the vehicle door, and the door anti-collision beam body 1 is in its width direction (see details). Figure 2 The cross section in the mm direction shown includes one or more U-shaped structures for enclosing one or more buffer cavities with the inner door panel 2.

[0037] Along the width direction of the door anti-collision beam body 1, at least one end of the door anti-collision beam body 1 is provided with a reinforcing structure 11, and the reinforcing structure 11 is located on the side of the door anti-collision beam body 1 away from the inner door panel 2.

[0038] In practice, the door anti-collision beam body 1 can be connected to the side of the inner door panel 2 near the outer door panel. That is, the door anti-collision beam body 1 is located between the inner door panel 2 and the outer door panel and is connected to the inner door panel 2. This allows it to form a buffer cavity with the inner door panel 2, so that when the vehicle is subjected to a side collision, it can buffer and absorb the energy of the collision, and at the same time transfer the collision force to the vehicle body to decompose the collision force. This can, to a certain extent, prevent the collision from intruding into the passenger compartment and causing injury to the occupants.

[0039] For example, the inner door panel 2 and the door anti-collision beam can be welded together.

[0040] For example, the cross-section of the door anti-collision beam body 1 itself can be as follows: Figure 2 The "W" shaped structure shown. From Figure 2 It is easy to see that the "W"-shaped structure can actually be regarded as including two "U"-shaped structures, and correspondingly, the door anti-collision beam body 1 and the inner door panel 2 can be enclosed to form two buffer cavities, thereby further improving the buffering energy absorption effect. However, it should be understood that the cross-section of the door anti-collision beam body 1 in the embodiments of this application may include more or fewer "U"-shaped structures, and this application does not limit this.

[0041] Along the width direction of the vehicle anti-collision beam body, the door anti-collision beam body 1 has a first end and a second end that are disposed opposite to each other, wherein at least one of the first end and the second end can be provided with a reinforcing structure 11, thereby effectively improving the structural strength of the entire door anti-collision beam, thereby improving the anti-collision effect and energy absorption effect of the door anti-collision beam, so as to improve the safety performance of the door in side collisions.

[0042] For example, the reinforcing structure 11 can be provided only at the first end, or only at the second end, or both at the first and second ends. See the attached document for details. Figure 2 As shown.

[0043] Furthermore, in this embodiment, the reinforcing structure 11 is located on the side of the door anti-collision beam body 1 away from the inner door panel 2. This avoids the welding operation between the inner door panel 2 and the door anti-collision beam body 1, as well as the sealing of the energy-absorbing cavity formed by the enclosing of the inner door panel 2 and the door anti-collision beam body 1, when the reinforcing structure 11 is placed on the side of the door anti-collision beam body 1 close to the inner door panel 2.

[0044] For example, the door anti-collision beam body 1 can be made of high-strength metal by stamping.

[0045] The door anti-collision beam provided in this embodiment includes a door anti-collision beam body 1, which is connected to the inner door panel 2 of the vehicle. The cross-section of the door anti-collision beam body 1 in its width direction may include one or more U-shaped structures to form one or more buffer cavities with the inner door panel 2. This allows for buffering and transferring of collision forces during a side collision, preventing the collision from intruding into the passenger compartment and causing injury to the occupants. Simultaneously, along the width direction of the door anti-collision beam body 1, a reinforcing structure 11 is provided at least at one end of the door anti-collision beam body 1, located on the side of the door anti-collision beam body 1 away from the inner door panel 2. This improves the structural strength and load-bearing capacity of the door anti-collision beam, thereby enhancing its anti-collision effect and improving the vehicle's collision safety performance. In addition, by placing the reinforcing structure 11 on the side of the door anti-collision beam body 1 away from the inner door panel 2, the installation of the reinforcing structure 11 can avoid affecting the sealing of the buffer cavity formed between the door anti-collision beam body 1 and the inner door panel 2.

[0046] Reference Figure 1 and Figure 2 As shown, in some embodiments, the reinforcing structure 11 includes a reinforcing flange 111 extending in a direction away from the inner door panel 2.

[0047] In other words, by providing a reinforcing flange 111 extending in a direction away from the inner panel 2 at at least one end of the door anti-collision beam body 1, the structural strength of the door anti-collision beam body 1 is increased by the reinforcing flange 111, thereby increasing the safety performance of the vehicle in side collisions.

[0048] Furthermore, by providing a reinforcing flange 111 extending in a direction away from the inner door panel 2, that is, extending along the direction from the inner door panel 2 to the outer door panel, that is, along the width direction of the vehicle (see reference). Figure 2 Extending in the yy direction shown, this setting allows the reinforcing flange 111 to extend in the direction of the impact force when the vehicle is subjected to a side collision, so as to more effectively utilize the reinforcing flange 111 to transmit and buffer the impact force.

[0049] For example, in other implementations, the reinforcing structure 11 can also be a reinforcing block or a reinforcing rib.

[0050] Reference Figure 2 As shown, in some embodiments, the reinforcing flange 111 is inclined in the direction away from the door anti-collision beam body 1 along the direction from the inner panel 2 of the door to the door anti-collision beam body 1.

[0051] In practice, the direction from the inner door panel 2 to the door anti-collision beam body 1 can be referenced. Figure 2As shown in the yy direction, the reinforcing flange 111 is inclined in the direction away from the door anti-collision beam body 1 along the yy direction. This can also make the reinforcing flange 111 and the door anti-collision beam body 1 enclose a large cavity, which can also be used to achieve buffering and energy absorption.

[0052] Meanwhile, when the reinforced flange 111 is tilted away from the door anti-collision beam body 1, it can also avoid the formation of a bending point at the transition connection between the reinforced flange 111 and the door anti-collision beam body 1. This avoids the problem of stress concentration at the bending point, which can easily lead to fatigue fracture. This can further improve the structural strength of the door anti-collision beam and improve the safety performance of the vehicle in side collisions.

[0053] In some embodiments, the reinforcing structure 11 can be integrally formed with the door anti-collision beam body 1 to save manufacturing processes and effectively improve the overall structural strength of the door anti-collision beam, thereby improving its collision bearing capacity and ultimately achieving the goal of improving the side collision performance of the vehicle.

[0054] Alternatively, in other implementations, the reinforcing structure 11 and the door anti-collision beam body 1 can be separately formed and then welded together. Furthermore, the material of the reinforcing structure 11 can be the same as the material of the door anti-collision beam body 1.

[0055] Reference Figure 3 As shown, in some embodiments, the door anti-collision beam body 1 is inclined toward the bottom wall of the inner door panel 2 along the length of the vehicle.

[0056] In other words, the door anti-collision beam body 1 is inclined towards the bottom wall of the inner door panel 2, meaning that the door anti-collision beam body 1 can be connected to different sides of the inner door panel 2, for example, referring to... Figure 3 As shown, one end of the door anti-collision beam body 1 is connected to one side of the inner door panel 2, and the other end of the door anti-collision beam body 1 is connected to the bottom wall or the other side of the inner door panel 2. This allows the door anti-collision beam to cover a larger collision area, so as to effectively utilize the door anti-collision beam for buffering and energy absorption and to realize the transmission of collision force.

[0057] For example, the door anti-collision beam body 1 can extend along the diagonal direction of the inner door panel 2, so that the area of ​​the collision area covered by the door anti-collision beam can be larger, so as to further effectively utilize the door anti-collision beam for buffering and energy absorption and to realize the transmission of collision force.

[0058] For example, multiple protruding ribs 12 can be provided on the door anti-collision beam body 1 to further enhance the structural strength of the door anti-collision beam body 1, improve the load-bearing capacity of the door anti-collision beam, and thus improve the anti-collision effect of the door anti-collision beam, thereby improving the collision safety performance of the vehicle. Specifically, the protruding ribs 12 can extend along the length direction of the door anti-collision beam body 1.

[0059] Reference Figures 1 to 3 As shown, this embodiment also provides a door inner panel assembly, including a door inner panel 2 and the aforementioned door anti-collision beam.

[0060] The specific structure and implementation principle of the door anti-collision beam in this embodiment are the same as those of the door anti-collision beam provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here. For details, please refer to the description of the above embodiments.

[0061] Reference Figure 3 As shown, in some embodiments, the door inner panel assembly includes a first additional anti-collision beam 3, which is correspondingly disposed with the bottom wall of the door inner panel 2 and connected to the door inner panel 2.

[0062] When a vehicle is subjected to a side collision, the bottom wall of the inner door panel 2 (i.e., the sill area) is subjected to a large impact and the strength of the bottom wall of the inner door panel 2 is usually weak. Therefore, a first additional anti-collision beam 3 is set at the bottom wall of the inner door panel 2 to effectively improve the structural strength at this location and thus prevent excessive collision intrusion at this location from causing injury to the occupants.

[0063] In the event of a vehicle collision, the collision force can be absorbed simultaneously by the door anti-collision beam body 1 and the first additional anti-collision beam 3 and transferred to the vehicle body for disintegration. This can effectively reduce door deformation and thus reduce the amount and speed of intrusion into the passenger compartment.

[0064] For example, the first additional anti-collision beam 3 can extend along the length of the bottom wall of the inner door panel 2 (refer to...). Figure 3 Extending in the direction shown in the figure, that is, the two are set in parallel, so as to effectively strengthen the structure at all positions of the bottom wall of the inner door panel 2.

[0065] For example, the first additional anti-collision beam 3 can be welded to the inner door panel 2. Alternatively, the first additional anti-collision beam 3 can also be made of a high-strength metal through stamping.

[0066] Reference Figure 3 As shown, in some embodiments, the first additional anti-collision beam 3 is located between the inner door panel 2 and the door anti-collision beam body 1, and the side of the first additional anti-collision beam 3 facing away from the inner door panel 2 is connected to the door anti-collision beam body 1.

[0067] In other words, there is an overlapping area between the first additional anti-collision beam 3, the inner door panel 2, and the door anti-collision beam body 1. One end of the first additional anti-collision beam 3 overlaps with the inner door panel 2 and the two are welded together. One end of the door anti-collision beam body 1 overlaps with the side of the first additional anti-collision beam 3 away from the inner door panel 2 and the two are welded together. This allows for pairwise connections between the inner door panel 2, the first additional anti-collision beam 3, and the door anti-collision beam body 1 at this location. This further enhances the structural strength of the entire inner door panel assembly, thereby improving the vehicle's side collision safety performance.

[0068] Reference Figure 3 As shown, in some embodiments, a reinforcing member 31 is provided on the first additional anti-collision beam 3.

[0069] By installing a reinforcing member 31 on the first additional anti-collision beam 3, the structural strength of the first additional anti-collision beam 3 can be further improved, thereby enhancing its load-bearing capacity during collision and improving its collision safety performance.

[0070] For example, the reinforcement 31 can be integrally formed with the first additional anti-collision beam 3 to save manufacturing steps and effectively improve the overall structural strength of the first additional anti-collision beam 3, thereby improving its collision bearing capacity and ultimately achieving the goal of improving the side collision performance of the vehicle.

[0071] Alternatively, in other implementations, the reinforcing member 31 can be formed separately from the main body of the first additional anti-collision beam 3 and then welded together.

[0072] For example, the material of the reinforcing member 31 can be Usibor 1800.

[0073] Reference Figure 3 As shown, in some embodiments, the reinforcing member 31 is located on the side of the first additional anti-collision beam 3 away from the inner door panel 2, thereby ensuring the reliability of the welded connection between the first additional anti-collision beam 3 and the inner door panel 2, and preventing the presence of the reinforcing member 31 from affecting the reliable fit between the first additional anti-collision beam 3 and the inner door panel 2 when the reinforcing member 31 is placed on the side of the first additional anti-collision beam 3 close to the inner door panel 2, thereby affecting the reliable welding between the two.

[0074] Reference Figure 3 As shown, in some embodiments, the reinforcing member 31 includes a reinforcing rib protruding in a direction away from the first additional anti-collision beam 3, the reinforcing rib extending along the length direction of the first additional anti-collision beam 3.

[0075] By setting reinforcing ribs that extend along the length of the first additional anti-collision beam 3, that is, along... Figure 3The extension in the x-direction shown allows the reinforcing rib to have a longer extension length, which can effectively improve the structural strength of the first additional anti-collision beam 3, thereby improving the safety performance of the vehicle in side collisions.

[0076] In some embodiments, the reinforcement 31 includes a plurality of reinforcements 31 arranged in parallel to further enhance the structural strength of the first additional anti-collision beam 3.

[0077] Reference Figure 3 As shown, in some embodiments, the door inner panel assembly further includes a second additional anti-collision beam 4 and an inner panel reinforcement plate 5. The door inner panel 2 includes two opposing sidewalls, and the inner panel reinforcement plate 5 is connected between the two sidewalls. One end of the second additional anti-collision beam 4 is connected to the inner panel reinforcement plate 5, and the other end of the second additional anti-collision beam 4 is connected to the door inner panel 2.

[0078] In other words, by further installing a second additional anti-collision beam 4 on the inner door panel 2, the structural strength of the inner door panel assembly can be further improved, thereby enhancing its collision load-bearing capacity and improving the vehicle's side collision safety performance.

[0079] In the event of a vehicle collision, the collision force can be absorbed simultaneously by the door anti-collision beam body 1 and the second additional anti-collision beam 4 and transferred to the vehicle body for disintegration. This can effectively reduce door deformation and thus reduce the amount and speed of intrusion into the passenger compartment.

[0080] It should be noted that, traditionally, a support plate is connected between the inner door panel 2 and the inner panel reinforcing plate 5 to prevent door dents. Since the support plate itself only serves a supporting function to prevent the outer door panel from denting, it is usually made of a metal with relatively weak structural strength and cannot provide collision protection. In this embodiment, the original support plate can be considered eliminated, and a second additional anti-collision beam 4, capable of providing collision protection, is installed in the original position of the support plate. Simultaneously, the second additional anti-collision beam 4 itself also provides support.

[0081] For example, the second additional anti-collision beam 4 itself is made of a high-strength metal, specifically a thermoformed metal material, which gives it excellent anti-collision performance.

[0082] Reference Figure 3 As shown, in some embodiments, the inner panel reinforcing plate 5 and the second additional anti-collision beam 4 are both located above the door anti-collision beam body 1, and the second additional anti-collision beam 4 is located between the inner panel reinforcing plate 5 and the door anti-collision beam body 1.

[0083] This configuration allows the second additional anti-collision beam 4 to cover the corresponding collision area above the door anti-collision beam body 1, so that in the event of a side collision, the anti-collision beams at different locations can buffer and absorb energy and transmit the collision force.

[0084] In some embodiments, the second additional anti-collision beam 4 is inclined toward the bottom wall of the inner door panel 2 along the length of the vehicle.

[0085] In other words, in order to enable the second additional anti-collision beam 4 to be connected to the inner panel reinforcement plate 5 and the side wall of the door inner panel 2 respectively, the second additional anti-collision beam 4 can be set along the length of the vehicle (refer to...). Figure 1 The second additional anti-collision beam 4 is tilted towards the bottom wall of the inner door panel 2 (as shown in the x direction) so that it can cover a larger collision area, so as to effectively utilize the second additional anti-collision beam 4 for buffering and energy absorption and to realize the transmission of collision force.

[0086] In some embodiments, the thickness d of the second additional anti-collision beam 4 satisfies: 1.2mm≦d≦1.4mm.

[0087] By reasonably setting the thickness d of the second additional anti-collision beam 4, it can have sufficient structural strength, thereby improving the safety performance of the vehicle in side collisions.

[0088] For example, the thickness d of the second additional anti-collision beam 4 can be 1.2mm, 1.3mm, or 1.4mm.

[0089] In addition, in this embodiment, a plating layer can be provided on the first additional anti-collision beam 3 and the second additional anti-collision beam 4 to achieve rust prevention.

[0090] In summary, the door inner panel assembly provided in this embodiment can absorb and transfer the intrusion energy during a side collision to the vehicle body simultaneously through the door anti-collision beam, the first additional anti-collision beam 3, and the second additional anti-collision beam 4, thereby effectively reducing door deformation and thus reducing the amount and speed of intrusion into the passenger compartment.

[0091] Reference Figures 1 to 3 As shown, this embodiment also provides a car door, including an outer door panel and an inner door panel assembly as described above, wherein the outer door panel is located on the side of the inner door panel 2 near the door anti-collision beam.

They will not be described in detail here, but can be referred to the description of the above embodiments.
