Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a door reinforcement structure and a vehicle. Background Technology

[0002] The smoothness of a car door's opening and closing, as well as its structural stability, directly impacts the overall quality of the vehicle and the user's driving experience. Car doors are typically assembled from components such as the inner door panel, outer door panel, and hinge mounts. In actual use, when a car door is opened, especially when the opening angle exceeds the design rated angle (i.e., over-open), the hinge joints and weak areas of the door must withstand significant lateral tensile and torque forces. This can easily lead to deformation issues such as dents in the inner door panel, bulges in the outer panel, or misalignment of the hinge mounts. These problems not only affect the door's aesthetic integrity but also result in poor smoothness of opening and closing. Utility Model Content

[0003] In view of this, this application aims to propose a door reinforcement structure to improve the smoothness of door opening and closing.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A door reinforcement structure includes an outer panel support plate, a crash beam, and a hinge reinforcement portion disposed between the outer panel and the inner panel of the door; and an outer panel reinforcement plate disposed between the outer panel support plate and the crash beam. The outer panel support plate and the anti-collision beam are both connected between the front end and the rear end of the inner panel of the car door. The outer panel reinforcement plate is located at the front of the outer panel support plate and is connected to the hinge reinforcement.

[0005] Furthermore, the hinge reinforcement includes a first hinge reinforcement plate and a second hinge reinforcement plate disposed on the inner panel of the door; The second hinge reinforcement plate is located below the first hinge reinforcement plate, and the front end of the outer plate reinforcement plate is connected to the second hinge reinforcement plate.

[0006] Furthermore, both the first hinge reinforcement plate and the second hinge reinforcement plate extend along the height direction of the inner panel of the door. The front end of the outer panel support plate is connected to the first hinge reinforcement plate and the inner door panel, and the front end of the anti-collision beam is connected to the second hinge reinforcement plate and the inner door panel.

[0007] Furthermore, a door lock reinforcing plate is provided at the rear end of the inner door panel, and the rear end of the outer panel support plate is connected to the inner door panel through the door lock reinforcing plate.

[0008] Furthermore, the top of the outer reinforcing plate is provided with an upwardly extending first protrusion, which is connected to the outer plate support plate; and / or, The bottom of the reinforcing plate of the outer panel is provided with a second protrusion extending downward, and the second protrusion is connected to the anti-collision beam.

[0009] Furthermore, the outer panel reinforcing plate has a first adhesive groove on the side facing the outer door panel, the first adhesive groove extending along the height direction of the outer panel reinforcing plate and used to fill expanding adhesive; and / or, The outer panel support plate has a second adhesive groove on the side facing the outer door panel. The second adhesive groove extends along the length of the outer panel support plate and is used to fill the expansion adhesive.

[0010] Furthermore, a protruding portion is formed in the middle of the outer support plate; The protruding portion protrudes towards the inner panel of the door, and extends along the length of the outer panel support plate.

[0011] Furthermore, the anti-collision beam is provided with a protruding portion, which protrudes towards the outer panel of the door. The protrusions are a plurality of portions spaced apart along the width direction of the anti-collision beam, and each of the protrusions extends along the length direction of the anti-collision beam.

[0012] Furthermore, from front to back, the anti-collision beam gradually tilts downwards; The distance between the anti-collision beam and the outer plate support plate gradually increases from front to back.

[0013] Compared with related technologies, this application has the following advantages: (1) The door reinforcement structure described in this application, by setting an outer panel support plate, an outer panel reinforcement plate, an anti-collision beam, and a hinge reinforcement part between the outer panel and the inner panel of the door, and connecting the outer panel reinforcement plate with the hinge reinforcement part, can effectively prevent the door from bending inward and causing local dents, thereby enhancing the overall rigidity and dent resistance of the door and improving its long-term durability. At the same time, it can also effectively reduce the deformation at the hinge position, which is beneficial to improving the smoothness of the door opening and closing.

[0014] (2) By including two hinge reinforcement plates in the hinge reinforcement part, it is not only easier to process and manufacture, but also easier to arrange the assembly sequence. Moreover, according to the different functions of the first hinge reinforcement plate and the second hinge reinforcement plate, plates of different materials and thicknesses can be manufactured separately, which can facilitate the lightweight design of the vehicle body while ensuring performance.

[0015] (3) By making the first hinge reinforcement plate and the second hinge reinforcement plate extend along the height direction of the inner panel of the door, the connection area between the hinge reinforcement and the inner panel of the door can be enhanced, which can make the hinge installation area have greater structural strength. At the same time, it can also make the front end of the door have better structural strength, which can effectively prevent the door from sagging too much due to insufficient rigidity when opening, especially when it is over-opened, which is conducive to further improving the stability of the door in the open state.

[0016] (4) Connecting the rear end of the outer panel support plate to the door lock reinforcement plate can not only improve the stability of the outer panel support plate, but also transform the longitudinal support force of the outer panel support plate into a rigid supplement to the rear end, which can further improve the installation strength of the door lock position, thereby effectively preventing deformation of the door lock area and causing abnormal noise due to component misalignment when the door is closed, which is conducive to improving the quietness of the door.

[0017] (5) By setting the first protrusion, the height position of the outer panel support plate can be better matched, which facilitates the connection between the outer panel reinforcement plate and the outer panel support plate, and also facilitates the transmission of force between the outer panel reinforcement plate and the outer panel support plate, thereby facilitating the distribution of external force to the entire door area.

[0018] By setting a second protrusion, not only can the height position of the anti-collision beam be better matched, making it easier to connect the outer panel reinforcement plate and the anti-collision beam, but it can also facilitate the transfer of force between the outer panel reinforcement plate and the anti-collision beam, thereby making it easier to distribute external force to the entire door area.

[0019] (6) By setting the first adhesive groove, after the expanding adhesive cures in the first adhesive groove, the outer panel reinforcing plate and the inner side of the outer door panel will form a tight abutment, increasing the effective connection area between the two. By setting the second adhesive groove, after the expanding adhesive cures in the second adhesive groove, the outer panel support plate and the inner side of the outer door panel will form a tight abutment, increasing the effective connection area between the two.

[0020] (7) By setting the protruding part, the bending and torsional stiffness of the outer plate support plate can be improved, and the bending deformation of the outer plate support plate can be effectively resisted. At the same time, the protruding part is designed to extend along the length direction, which can strengthen the stiffness of the entire length direction of the outer plate support plate, thereby reducing stress concentration caused by insufficient local stiffness.

[0021] (8) By setting multiple protrusions extending along the length of the anti-collision beam, it is equivalent to forming multiple longitudinal reinforcing ribs on the anti-collision beam body, which can significantly improve the torsional stiffness and bending strength of the anti-collision beam itself. At the same time, the protrusions can also form a force transmission path, which can quickly disperse the external force borne by the anti-collision beam to the entire beam body and the inner panel of the door.

[0022] (9) From front to back, the anti-collision beam gradually tilts downward, and the distance between the anti-collision beam and the outer panel support plate gradually increases from front to back. This arrangement allows for a smaller distance between the front end of the anti-collision beam and the outer panel support plate, which increases the stiffness of the hinge reinforcement, i.e., the hinge position. This further suppresses the deformation of the hinge position caused by over-opening or frequent opening and closing, prevents the door from sinking, and helps ensure the stability of the door opening and closing.

[0023] Another object of this application is to provide a vehicle having a door reinforcement structure as described above.

[0024] The vehicle described in this application, by setting the door reinforcement structure as described above, can enhance the overall rigidity and dent resistance of the door, which is beneficial to improve the stability of the door when it is open and reduce the impact noise caused by the misalignment of parts when the door is closed, thus achieving better quality of use.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides a door reinforcement structure to improve the stability of the door when it is open and to reduce abnormal noises when the door is closed.

[0034] In related technologies, the car door, as a key moving component of the vehicle body, directly affects the overall quality of the vehicle and the user's driving experience due to its smooth opening and closing, structural stability, and quiet operation. Car doors are typically assembled from components such as the inner door panel, outer door panel, and hinge mounting brackets. In actual use, when the door is opened, especially when the opening angle exceeds the design rated angle (i.e., over-open state), the hinge connection and weak areas of the door must withstand significant lateral tensile forces and torques.

[0035] At this time, deformation problems such as dents in the inner door panel, bulges in the outer door panel, or misalignment of the hinge mounting seat may occur. This not only affects the integrity of the door's appearance but also makes the door opening and closing less smooth. In addition, when the door is closed, the contact position between the door latch and the lock body may deviate, easily causing knocking noises and other abnormal noises when closing the door, which will greatly reduce the quietness and comfort of the user.

[0036] In view of this, in order to overcome the shortcomings of related technologies, the door reinforcement structure of this embodiment combines... Figures 1 to 4 As shown, the overall design includes an outer panel support plate 1, a crash beam 2, and a hinge reinforcement located between the outer door panel and the inner door panel 7, as well as an outer panel reinforcement plate 3 located between the outer panel support plate 1 and the crash beam 2. The outer panel support plate 1 and the crash beam 2 are both connected between the front and rear ends of the inner door panel 7, and the outer panel reinforcement plate 3 is located at the front of the outer panel support plate 1 and is connected to the hinge reinforcement.

[0037] The door reinforcement structure of this embodiment, by setting an outer panel support plate 1, an anti-collision beam 2, an outer panel reinforcement plate 3, and a hinge reinforcement part between the outer door panel and the inner door panel 7, and connecting the front end of the outer panel reinforcement plate 3 to the hinge reinforcement part, can effectively prevent deformation problems such as inward bending and local dents of the door, enhance the overall rigidity and dent resistance of the door, thereby improving the long-term durability of the door and enhancing its safety for passengers. Furthermore, the outer panel reinforcement plate 3, outer panel support plate 1, anti-collision beam 2, and the hinge reinforcement parts and door lock reinforcement plates 6 at both ends are connected together to form a better force transmission channel. The overall connection ensures more reasonable transmission of collision energy, effectively disperses collision force, reduces door deformation, and protects occupant safety.

[0038] Meanwhile, since the outer panel reinforcement plate 3 is connected to the hinge reinforcement part, the overall strength of the outer panel reinforcement plate 3, the outer panel support plate 1, and the anti-collision beam 2 can effectively reduce the deformation at the hinge position, which is conducive to ensuring the smooth opening and closing of the car door. It can also effectively avoid the increase in opening and closing resistance caused by hinge deformation and door sinking, which is conducive to reducing the impact noise caused by component misalignment when the car door is closed, improving the quietness of the car door and enhancing the driving experience.

[0039] Based on the above overview, specifically, the outer door panel is typically made of thin steel sheet through stamping. Its shape matches the external contour of the door, and its surface is relatively smooth to meet the requirements of the vehicle's exterior styling. Furthermore, when the outer door panel is connected to the inner door panel 7, the edges of the outer panel are usually connected to the inner panel assembly using an edge-wrapping process. The inner door panel 7, as an important support plate, is generally made of thicker thin steel sheet and has multiple raised and recessed structures formed on it for installing accessories such as door locks, window regulator switches, and door handles.

[0040] This embodiment does not involve structural improvements to the outer door panel and the inner door panel 7; specific implementation details can be found in related technologies and will not be elaborated here. Additionally, it should be mentioned that the door reinforcement structure in this embodiment can be installed on the front door or the rear door of the vehicle as needed.

[0041] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the anti-collision beam 2 gradually slopes downwards from front to back, and the distance between the anti-collision beam 2 and the outer panel support plate 1 gradually increases from front to back. This arrangement allows for a smaller distance between the front end of the anti-collision beam 2 and the outer panel support plate 1, which increases the stiffness of the hinge reinforcement, i.e., the hinge position. This further suppresses deformation of the hinge position caused by over-opening or frequent opening and closing, prevents the door from sagging, and helps ensure the stability of the door opening and closing.

[0042] Meanwhile, the gradually increasing distance between the rear end of the anti-collision beam 2 and the outer panel support plate 1 increases the connection area between them and the inner door panel 7, allowing the structural reinforcement to more evenly cover the entire door, further improving the door's torsional resistance. Moreover, during a collision, the outer panel support plate 1 and the anti-collision beam 2 can transfer the collision energy to a larger area of ​​the inner door panel 7 for dissipation and decomposition. This allows for energy decomposition and dissipation through the coordinated deformation of the entire door structure, effectively dispersing the collision force, reducing door deformation, and protecting occupant safety.

[0043] In specific implementation, combined with Figures 1 to 4 As shown in the diagram, in this embodiment, the outer panel support plate 1 extends along the front-to-back direction when the door is closed. Furthermore, the outer panel support plate 1 is positioned near the window frame, approximately at the center of the door's height, to provide good support for the outer door panel, preventing inward deformation and maintaining the overall aesthetics of the door. The front end of the anti-collision beam 2 is close to the front end of the outer panel support plate 1, while its rear end slopes downward and connects approximately to the lower rear corner of the inner door panel 7.

[0044] This design allows the outer panel support plate 1 and the anti-collision beam 2 to not only provide good reinforcement at the hinge position, but also to achieve a large-scale connection with the inner door panel 7. It also gives the outer door panel as a whole good anti-dent stiffness, providing better protection for passengers.

[0045] In some exemplary embodiments, the anti-collision beam 2 has protrusions 201 that protrude towards the outer side of the door panel. Multiple protrusions 201 are spaced apart along the width direction of the anti-collision beam 2, and each protrusion 201 extends along the length direction of the anti-collision beam 2. By providing multiple protrusions 201 extending along their length direction on the anti-collision beam 2, it is equivalent to forming multiple longitudinal reinforcing ribs on the anti-collision beam 2 body, which can significantly improve the torsional stiffness and bending strength of the anti-collision beam 2 itself.

[0046] At the same time, the protruding part 201 can also form a force transmission path, which can quickly disperse the external force borne by the anti-collision beam 2 to the entire beam and the inner panel of the door, further improving the anti-dent performance of the door. It can also facilitate the support of the anti-collision beam 2 on the outer panel of the door, and can have a good support effect on the outer panel of the door, which helps to reduce the dent caused by the loss of support of the outer panel of the door due to the force.

[0047] As a specific embodiment, the material of the anti-collision beam 2 can be any material commonly used in related technologies. Furthermore, in conjunction with... Figure 5 and Figure 6 As shown, the protrusions 201 are two spaced apart along the width direction of the anti-collision beam 2, making the cross-section of the anti-collision beam 2 "m" shaped. Furthermore, to further improve the support effect of the anti-collision beam 2 on the outer door panel, such as... Figure 5 As shown, a third adhesive groove 2011 is provided on each protrusion 201. Furthermore, there are multiple third adhesive grooves 2011 on each protrusion 201 that are spaced apart along the length direction of the anti-collision beam 2, and each third adhesive groove 2011 is an elongated strip extending along the length direction of the anti-collision beam 2.

[0048] This design allows for a larger amount of expanding adhesive to be filled in each third adhesive groove 2011, improving the support effect of the anti-collision beam 2 on the outer door panel. Simultaneously, the multiple third adhesive grooves 2011 provide more support points between the anti-collision beam 2 and the outer door panel, resulting in better support and further reducing the risk of dents in the outer door panel due to loss of support under stress.

[0049] Furthermore, as a further implementation method, such as Figure 5 As shown, the third adhesive grooves 2011 on the two protrusions 201 are staggered along the length of the anti-collision beam 2. This ensures that the anti-collision beam 2 has connection points with the outer door panel along its entire length, further guaranteeing the support effect on the outer door panel.

[0050] It should be noted that the number of protrusions 201 is not limited to... Figure 5 As shown in the figure, there can be three, four, or more, or even just one. The shape and arrangement of the third adhesive tank 2011 are not limited to those shown in the figure; it only needs to be able to fill the expanding adhesive.

[0051] In this embodiment, in some exemplary implementations, a protruding portion 101 is formed in the middle of the outer panel support plate 1. This protruding portion 101 protrudes towards the inner door panel 7 and extends along the length direction of the outer panel support plate 1. The provision of this protruding portion 101 can increase the moment of inertia of the cross-section of the outer panel support plate 1, significantly improving its bending and torsional stiffness, and effectively resisting the bending deformation of the outer panel support plate 1. At the same time, the design of extending the protruding portion 101 along the length direction can strengthen the stiffness of the outer panel support plate 1 along the entire length direction, which helps to ensure that the outer panel support plate 1 is subjected to uniform stress, thereby reducing stress concentration caused by insufficient local stiffness.

[0052] In specific implementation, you can refer to Figure 7 and Figure 8 As shown, the protruding portion 101 is positioned approximately at the center of the outer plate support plate 1 in the width direction. Therefore, when the outer plate support plate 1 is subjected to lateral forces or torques, uneven stress caused by offset can be effectively avoided, further improving the overall balance of bending and torsional resistance of the outer plate support plate 1. Furthermore, to further improve the strength and stiffness of the outer plate support plate 1, such as... Figure 8As shown, the outer panel support plate 1 has flanges that bend toward the inner door panel 7 on both the upper and lower sides, which can effectively resist the lateral deformation of the outer panel support plate 1 in the width direction.

[0053] Furthermore, a plurality of protrusions are provided on the upper side of the protruding portion 101, spaced apart along the length direction of the outer plate support plate 1. These protrusions can provide local reinforcement to the protruding portion 101, effectively preventing local cracking or deformation of the protruding portion 101 due to long-term stress. It can be understood that, in addition to the single protruding portion 101 located in the middle of the outer plate support plate 1, multiple protruding portions 101 can be provided at intervals along the width direction of the outer plate support plate 1, as required by the design.

[0054] In some exemplary embodiments, the outer panel support plate 1 has a second adhesive groove 1011 on the side facing the outer door panel. The second adhesive groove 1011 extends along the length of the outer panel support plate 1 and is used to fill the expanding adhesive. By providing the second adhesive groove 1011, the expanding adhesive that tightly abuts against the outer door panel can be filled, thereby more evenly transmitting the force between the outer door panel and the outer panel support plate 1, which helps to improve the stability and rigidity of the overall door structure. Moreover, the expanding adhesive has a certain deformation capability, and after filling and curing, it can fill the small gaps between the outer panel support plate 1 and the outer door panel caused by manufacturing tolerances, which can further reduce the risk of local dents or deformations of the outer door panel.

[0055] In this embodiment, as Figure 7 As shown, second adhesive grooves 1011 are provided on both the upper and lower sides of the outer panel support plate 1, and multiple second adhesive grooves 1011 on each side are spaced apart along the length of the outer panel support plate 1. This arrangement allows the outer panel support plate 1 to provide multiple support points for the door outer panel, further improving the dent resistance of the door outer panel and the overall durability of the door. Furthermore, as a further embodiment, it is still composed of... Figure 7 As shown, the second adhesive grooves 1011 on the upper and lower sides of the outer panel support plate 1 are alternately arranged along the length of the outer panel support plate 1. This arrangement ensures that the outer panel support plate 1 has connection points to the outer door panel along its entire length, which not only improves the uniformity of reinforcement of the outer door panel but also effectively prevents failure in a single area due to excessive stress.

[0056] In addition, combined Figure 1 and Figure 2 As shown in the diagram, the front end of the outer panel reinforcing plate 3 in this embodiment is approximately flush with the front ends of the outer panel support plate 1 and the anti-collision beam 2. Furthermore, the outer panel reinforcing plate 3 is positioned to fill the gap between the front ends of the outer panel support plate 1 and the anti-collision beam 2. This provides a better reinforcement effect for the front end of the door and effectively improves the structural strength of the hinge position, thus effectively preventing deformation of the hinge position that could lead to difficulty in opening and closing the door.

[0057] Specifically, such as Figure 9 As shown, in this embodiment, the upper edge of the outer panel reinforcing plate 3 is straight, while the lower edge is bent, resulting in the outer panel reinforcing plate 3 comprising a front portion whose width gradually increases from front to back, and a rear portion whose width gradually decreases from front to back. The front portion conforms to the gap between the outer panel support plate 1 and the front end of the anti-collision beam 2, thereby providing better reinforcement to the hinge position at the front of the door.

[0058] Additionally, in some exemplary embodiments, such as Figure 9 As shown, the top of the outer panel reinforcing plate 3 is provided with an upwardly extending first protrusion 301, which is connected to the outer panel support plate 1. By providing the first protrusion 301, on the one hand, it can better adapt to the height position of the outer panel support plate 1, facilitating the connection between the outer panel reinforcing plate 3 and the outer panel support plate 1. On the other hand, the first protrusion 301 can also facilitate the transmission of force between the outer panel reinforcing plate 3 and the outer panel support plate 1, thereby facilitating the distribution of external force throughout the entire door area.

[0059] In some exemplary embodiments, the bottom of the outer panel reinforcing plate 3 is provided with a downwardly extending second protrusion 302, which is connected to the outer panel support plate 1. By providing the second protrusion 302, it can not only better adapt to the height position of the anti-collision beam 2, but also facilitate the connection between the outer panel reinforcing plate 3 and the anti-collision beam 2. On the other hand, the second protrusion 302 can also facilitate the transmission of force between the outer panel reinforcing plate 3 and the anti-collision beam 2, thereby facilitating the distribution of external force to the entire door area.

[0060] In specific implementation, such as Figures 7 to 10 As shown in the figure, in this embodiment, the outer plate reinforcing plate 3 is provided with both a first protrusion 301 and a second protrusion 302. Furthermore, to improve the connection strength between the first protrusion 301 and the outer plate support plate 1, two first protrusions 301 are spaced apart, and each first protrusion 301 is also provided with a boss to improve the structural strength of the first protrusion 301. This effectively improves the connection strength between the first protrusion 301 and the outer plate support plate 1, and effectively prevents tearing at the connection point. It should also be noted that, in addition to the single first protrusion shown in the figure, multiple first protrusions 301 can be spaced apart according to design requirements.

[0061] In addition, such as Figure 9As shown, the second protrusion 302 is located at the connection between the front and rear portions of the outer panel reinforcing plate 3. Furthermore, to improve the connection strength between the second protrusion 302 and the anti-collision beam 2, a boss is also provided on the second protrusion 302 to enhance its structural strength, thereby effectively improving the connection strength between the first protrusion 301 and the anti-collision beam 2. It should also be noted that, in addition to the single second protrusion shown in the figure, multiple second protrusions 302 can be spaced apart according to design requirements.

[0062] In some exemplary embodiments, the outer panel reinforcing plate 3 has a first adhesive groove 303 on the side facing the outer door panel. The first adhesive groove 303 extends along the height direction of the outer panel reinforcing plate 3 and is used to fill the expanding adhesive. Thus, after the expanding adhesive cures in the first adhesive groove 303, it will form a tight contact with the inner side of the outer door panel, increasing the effective connection area between the two. This allows the local pressure borne by the outer door panel to be evenly transmitted to the outer panel reinforcing plate 3 through the expanding adhesive, avoiding loosening of the connection or denting of the outer panel due to excessive force at a single point.

[0063] Especially when the car door is opened too wide, the outer panel reinforcing plate 3 needs to work with the outer panel support plate 1 to withstand lateral tension. The design of the expanding adhesive ensures that there is no relative displacement between the outer door panel and the outer panel reinforcing plate 3, providing a stable force-bearing foundation for the connection point between the first protrusion 301 and the outer panel support plate 1, thereby effectively preventing overall support failure due to outer panel misalignment. Moreover, the first adhesive groove 303 is set along the height direction of the outer door panel, while the second adhesive groove 1011 on the outer panel support plate 1 is set along the length direction of the outer door panel. The expanding adhesive in both can form a grid-like connection structure with the outer door panel, which can improve the support effect of the outer door panel and effectively disperse the external force borne by the outer door panel.

[0064] In this embodiment, during specific implementation, it can be as follows: Figure 9 As shown, multiple first adhesive grooves 303 are spaced apart along the length of the outer plate reinforcing plate 3, and a first adhesive groove 303 is provided at the front end of the outer plate reinforcing plate 3 to further enhance the reinforcement effect on the hinge position and reduce hinge deformation. Additionally, to facilitate the connection between the outer plate reinforcing plate 3 and the hinge reinforcing plate, as shown... Figure 9 As shown, a third protrusion 304 extending forward is provided at the front end of the outer plate reinforcing plate 3. The third protrusion 304 is bent to give it better structural strength, thereby enabling the outer plate reinforcing plate 3 and the hinge reinforcing part to have better connection strength, which can effectively prevent connection failure due to vibration.

[0065] It should be noted that the number of the first protrusion 301 is not limited to... Figure 9 The number of the first adhesive tanks 303 shown in the figure can be adjusted according to design requirements. Furthermore, the number of first adhesive tanks 303 is not limited to that shown in the figure and can be determined according to design requirements.

[0066] In this embodiment, in some exemplary implementations, the hinge reinforcement includes a first hinge reinforcement plate 4 and a second hinge reinforcement plate 5 disposed on the inner door panel 7. The second hinge reinforcement plate 5 is located below the first hinge reinforcement plate 4, and the front end of the outer panel reinforcement plate 3 is connected to the second hinge reinforcement plate 5. Here, by including two hinge reinforcement plates in the hinge reinforcement, not only is manufacturing easier and processing costs reduced, but the assembly sequence is also more easily arranged.

[0067] In addition, during the opening and closing process of the door hinge, an upper torque and a lower supporting force load are generated. The first hinge reinforcement plate 4 can directly bear the installation torque of the upper part of the hinge, and at this time, the first hinge reinforcement plate 4 is allowed to resist the deformation caused by torque through the characteristics of the thick plate. The second hinge reinforcement plate 5 mainly bears the lower supporting force, and through its connection with the outer plate reinforcement plate 3, it transfers part of the load to the outer plate reinforcement plate 3, and then further to the outer plate support plate 1.

[0068] Therefore, by using a first hinge reinforcement plate 4 and a second hinge reinforcement plate 5 separately for the hinge reinforcement part, different materials and thicknesses of the plates can be selected and manufactured separately according to the different functions of the first hinge reinforcement plate 4 and the second hinge reinforcement plate 5. This can ensure performance while facilitating lightweight vehicle body design.

[0069] Combination Figure 1 , Figure 10 and Figure 11 As shown, in some exemplary embodiments, both the first hinge reinforcement plate 4 and the second hinge reinforcement plate 5 extend along the height direction of the inner door panel 7. The front end of the outer panel support plate 1 is connected to the first hinge reinforcement plate 4 and the inner door panel 7, and the front end of the anti-collision beam 2 is connected to the second hinge reinforcement plate 5 and the inner door panel 7.

[0070] By extending both the first hinge reinforcement plate 4 and the second hinge reinforcement plate 5 along the height direction of the inner door panel 7, the connection area between the hinge reinforcement and the inner door panel 7 is increased, resulting in greater structural strength in the hinge mounting area. Simultaneously, the front end of the entire door also exhibits good structural strength, effectively preventing excessive sagging due to insufficient rigidity, especially when opening excessively. Furthermore, by connecting the front end of the outer panel support plate 1 to both the first hinge reinforcement plate 4 and the inner door panel 7, and the front end of the anti-collision beam 2 to both the second hinge reinforcement plate 5 and the inner door panel 7, the overall structural strength of the door is improved.

[0071] This allows the outer panel support plate 1, the first hinge reinforcement plate 4, and the inner door panel 7 to be connected simultaneously, as well as the anti-collision beam 2, the second hinge reinforcement plate 5, and the door itself to be connected simultaneously. Under the action of the outer reinforcement plate, these two components and the inner door panel 7 form a single unit. At this point, the structural strength of each component ensures good strength at the front end of the door, effectively preventing hinge deformation and further improving the stability of the door when opening. It also effectively prevents component misalignment due to hinge deformation, thus avoiding abnormal noise when the door closes.

[0072] In specific implementation, it can be as follows: Figure 2 , Figure 10 and Figure 11 As shown, the second hinge reinforcement plate 5 is longer than the first hinge reinforcement plate 4, and the top of the second hinge reinforcement plate 5 protrudes upwards towards the anti-collision beam 2 to be welded to the outer panel reinforcement plate 3. Furthermore, similar to related technologies, the inner door panel 7 generally includes a main panel portion opposite to the outer door panel, a side panel portion located at the edge of the main panel portion, and a flange portion located at the edge of the side panel portion.

[0073] In addition, to improve the connection strength between the first hinge reinforcement plate 4 and the second hinge reinforcement plate 5 and the inner door panel 7, such as... Figure 11 As shown, the cross-sections of the first hinge reinforcing plate 4 and the second hinge reinforcing plate 5 are both Z-shaped, and include a main plate c attached to the side portion, and a first flange a and a second flange b disposed on both sides of the main plate c. The first flange a is welded to the main plate c portion of the inner door panel 7, and the second flange b is welded to the flange portion of the inner door panel 7. In this embodiment, the outer panel reinforcing plate 3 is specifically welded to the second flange b of the second hinge reinforcing plate 5.

[0074] In some exemplary embodiments, a door lock reinforcing plate 6 is provided at the rear end of the inner door panel 7, and the rear end of the outer panel support plate 1 is connected to the inner door panel 7 via the door lock reinforcing plate 6. Because the door lock needs to withstand the axial force generated by the door impact when closing, long-term use can easily lead to deformation of the door lock mounting base due to insufficient regional rigidity, causing the lock body to loosen, the door to jam, or abnormal noise. By setting the door lock reinforcing plate 6, not only can a localized reinforcement structure be formed in the door lock mounting area, significantly improving the torsional stiffness and deformation resistance of this area, but it can also disperse the concentrated impact force borne by the door lock when closing, transferring the force to a larger area of ​​the inner door panel 7.

[0075] In addition, connecting the rear end of the outer panel support plate 1 to the door lock reinforcing plate 6 not only improves the stability of the outer panel support plate 1, but also transforms the longitudinal support force of the outer panel support plate 1 into a rigid supplement to the rear end. By utilizing the structural strength of the outer panel support plate 1, the installation strength of the door lock position can be further improved, thereby effectively preventing deformation of the door lock area and avoiding abnormal noise caused by component misalignment when the door is closed, which helps to improve the quietness of the door.

[0076] In specific implementation, such as Figure 12 and Figure 13 As shown, the door lock reinforcement plate 6 includes a transverse portion 601 connected to the main board c portion of the inner door panel 7, a longitudinal portion 602 connected to the side panel portion, and a bent portion 603 provided on the longitudinal portion 602, which is connected to the rear end of the outer panel support plate 1. By adopting this structure, the door lock reinforcement plate 6 not only has better structural strength, but also facilitates the connection between the door lock reinforcement plate 6 and the inner door panel 7 and the outer panel support plate 1.

[0077] Based on the above description, in the specific assembly of the door reinforcement structure of this embodiment, the first hinge reinforcement plate 4, the second hinge reinforcement plate 5, and the door lock reinforcement plate 6 can be welded together with the inner door panel 7 to form an inner panel sub-assembly. In addition, the outer panel support plate 1 is welded to the outer panel reinforcement plate 3 to form an outer panel sub-assembly. Then, the anti-collision beam 2 is welded to the inner panel sub-assembly, and then to the outer panel sub-assembly to form the inner panel assembly. Finally, the inner panel assembly is connected to the outer door panel.

[0078] It is worth noting that, regarding the door reinforcement structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 13 As shown, it may include, for example, an outer panel support plate 1, a crash beam 2, and a hinge reinforcement located between the outer panel and the inner panel 7 of the door, as well as an outer panel reinforcement plate 3 located between the outer panel support plate 1 and the crash beam 2. The outer panel support plate 1 and the crash beam 2 are both connected between the front end and the rear end of the inner panel 7 of the door, and the outer panel reinforcement plate 3 is located at the front of the outer panel support plate 1 and is connected to the hinge reinforcement.

[0079] Among them, from front to back, the anti-collision beam 2 gradually tilts downward, and the distance between the anti-collision beam 2 and the outer plate support plate 1 gradually increases from front to back.

[0080] The hinge reinforcement includes a first hinge reinforcement plate 4 and a second hinge reinforcement plate 5 disposed on the inner door panel 7. The front end of the outer panel support plate 1 is connected to the first hinge reinforcement plate 4 and the inner door panel 7 together. The front end of the anti-collision beam 2 is connected to the second hinge reinforcement plate 5 and the inner door panel 7 together. The rear end of the outer panel support plate 1 is connected to the inner door panel 7 through the door lock reinforcement plate 6.

[0081] The outer panel reinforcing plate 3 has a first adhesive groove 303 on the side facing the outer door panel. The first adhesive groove 303 extends along the height direction of the outer panel reinforcing plate 3 and is used to fill the expanding adhesive. The outer panel support plate 1 has a second adhesive groove 1011 on the side facing the outer door panel. The second adhesive groove 1011 extends along the length direction of the outer panel support plate 1 and is used to fill the expanding adhesive.

[0082] In the preferred embodiment of the above door reinforcement structure, the specific setting and arrangement of the outer panel reinforcement plate 3, the outer panel support plate 1 and the anti-collision beam 2, etc., can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the outer panel reinforcement plate 3, the outer panel support plate 1 and the anti-collision beam 2, etc., can also be referred to the description in the above exemplary embodiments.

[0083] The door reinforcement structure in this embodiment, with the design described above, enhances the overall rigidity and dent resistance of the door, thereby improving its long-term durability. Simultaneously, it effectively reduces deformation at the hinge location, improving stability when the door is open and preventing increased opening and closing resistance due to hinge deformation and door sagging. This also helps reduce impact noises caused by component misalignment when the door is closed.

[0084] An embodiment of the second aspect of this application provides a vehicle having the above-described door reinforcement structure.

[0085] The vehicle in this embodiment, by setting the door reinforcement structure as described above, can enhance the overall rigidity and dent resistance of the door, which is beneficial to the smoothness of the door opening and closing, and reduces the impact noise caused by component misalignment when the door is closed, thus achieving better quality of use.

[0086] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations.
