Description

Technical Field

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

[0002] In the modern automotive industry, off-road vehicles not only meet daily travel needs, but also become an important vehicle for consumers to pursue outdoor fun and express their individuality. As a key component of the appearance and function of off-road vehicles, reasonable door modification and reserved structure design has become an important part of meeting the diversified needs of users.

[0003] Currently, the existing technical solution for door modification in the industry is to directly install decorative parts on the exterior sheet metal surface of the door, pre-setting interfaces for later modifications. This technical approach exposes the necessary connecting components directly on the door surface, providing a foundation for subsequent modifications and satisfying some modification needs to a certain extent. This has become the door modification pre-installation method adopted by most automakers at present.

[0004] However, the existing technical solutions have the following drawbacks: the connection structure between the exposed decorative parts and the door sheet metal is prone to vibration transmission during vehicle operation, which damages the original acoustic and vibration characteristics of the door, reduces the vehicle's NVH (vibration, noise, and harshness) performance, and affects the ride comfort of passengers. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a door and a vehicle.

[0007] To achieve the above objectives, in a first aspect, this application provides a vehicle door, comprising: The outer panel has a first side and a second side on its two sides, respectively. A connecting plate is disposed on the first side of the outer plate and is connected to the outer plate; At least one first connecting hole is provided. The first connecting hole is formed on the connecting plate and is used for the connector to pass through to fix the mounting component.

[0008] In the technical solution, the outer panel of the vehicle is not pre-installed with any exposed decorative parts or connecting protrusions when it leaves the factory. Only when installing the additional parts, the connecting holes are opened on the outer panel to ensure that the appearance of the outer panel is simple and flat and consistent with the overall design style of the vehicle. This solves the problem of the appearance being cluttered due to the direct addition of decorative parts to the exterior sheet metal in the existing technology.

[0009] The connecting plate can disperse the vibration stress of the outer panel during driving and prevent the outer panel from vibrating at high frequency due to insufficient rigidity. This solution has no exposed connecting structure, such as the external bracket and protruding buckle of the existing technology, which can reduce the wind noise generated by the airflow impacting the exposed structure during driving, as well as the collision noise between the exposed structure and the outer panel during vibration.

[0010] The first connection hole is located on the connection plate on the first side of the outer panel. The first connection hole can be connected to conventional fasteners such as bolts through a preset thread, or to rivets or expansion screws. It supports different weights and types of add-ons, and the connection method is standardized, reducing the difficulty of operation for users to modify later.

[0011] In some embodiments of this application, the connecting plate includes: A reinforcing section, wherein the reinforcing section is used to increase the strength of the outer panel; The connecting part is integrally formed with the reinforcing part, and the connecting part is located on the side of the connecting plate corresponding to the mounting part; The first connecting hole is formed on the connecting part.

[0012] In the technical solution, the reinforcement section is used to improve the overall strength of the outer panel. It can compensate for the insufficient rigidity of the outer panel itself by covering key stress areas that are not visible on the surface. For the bumpy and impact scenarios often encountered by off-road vehicles, it can reduce the high-frequency deformation of the outer panel caused by vibration and avoid the problem of local dents in the outer panel caused by relying solely on the connecting structure to bear the weight. The connecting part is used to connect the mounting parts. By integrally forming with the reinforcing part, the load of the mounting parts is directly transferred to the reinforcing part, optimizing the force transmission path, avoiding force concentration, and solving the problems of assembly gap and force transmission breakage caused by the separation of the traditional reinforcing parts and connecting parts.

[0013] In some embodiments of this application, the car door further includes: A second connecting hole is formed on the outer plate; An add-on component, wherein the add-on component is disposed on the second side of the outer panel; At least one third connection hole is provided, and the third connection hole is opened on the mounting component; The second connector passes through the third connecting hole, the second connecting hole and the first connecting hole in sequence, and the second connector is connected to the corresponding first connecting hole.

[0014] In the technical solution, the mounting component is located on the second side of the outer panel, which is typically the visible surface. The connecting plate is located on the first side of the outer panel, which is typically a non-visual surface. Both the first connecting component and the first connecting hole are located on the non-visual surface of the outer panel. Only a pre-set second connecting hole needs to be provided on the surface of the outer panel. The second connecting hole can be hidden by process design when not modified, and it can be adapted to the shape and lines of the outer panel.

[0015] The second connector passes through the third connecting hole of the add-on, the second connecting hole of the outer plate, and the first connecting hole of the connecting plate in sequence. Through this through-fixing, the add-on, the outer plate, and the connecting plate can form a rigid whole. Even if the add-on is installed later, there will be no vibration or noise due to loose connection, thus optimizing NVH performance from a structural perspective.

[0016] In some embodiments of this application, the first connecting hole is provided with threads, the second connecting member is a bolt, and the bolt and the first connecting hole are connected by thread engagement.

[0017] In the technical solution, the connecting plate is located on the first side of the outer plate, an area that is typically narrow. If a bare hole design is used, a nut needs to be added to the other side of the connecting plate to secure the bolts. The first connecting hole with an internal thread eliminates the need for an extra nut; the bolts can simply be threaded through the add-on, the outer plate, and the connecting plate from the second side of the outer plate and tightened directly into the threaded connecting hole. No special tools are required, solving the assembly difficulties caused by the narrow space on non-exterior surfaces and lowering the operational threshold for users to perform later modifications.

[0018] In some embodiments of this application, the contact surface at the first connection hole on the connecting plate protrudes to the side away from the outer plate to improve the connection strength.

[0019] In the technical solution, the connecting plate, as the load-bearing area of ​​the modified structure, needs to withstand the weight of the added components and the vibration load during vehicle operation. If the area of ​​the connecting plate corresponding to the first connecting hole is a plane, the stiffness of this area depends only on the thickness of the connecting plate itself, and it is prone to bending or shear deformation under load. The structure protruding away from the outer panel is equivalent to forming a local reinforcing boss at the position of the connecting plate corresponding to the first connector. The boss makes the effective thickness of this area greater than other areas of the connecting plate, thus increasing local stiffness. The reinforced design of the protrusion allows the connecting plate to more stably withstand the tensile and lateral shear forces transmitted by the second connector, preventing the connecting plate from breaking or failing due to insufficient stiffness, and solving the problem of insufficient load-bearing capacity after modification of existing technologies.

[0020] In some embodiments of this application, a first connector is further included, which is disposed on a protrusion of the connecting plate or between the outer plate and the connecting plate.

[0021] In the technical solution, when the first connector is set as the connecting component, the assembly tolerance between the outer plate and the connecting plate can be compensated by the connector between the outer plate and the connecting plate, without the need for high machining accuracy of the connecting plate, thus reducing production costs. When installing the add-on, if the thread of the first connecting hole is damaged due to misoperation, it can be repaired by the first connector on the protrusion, without the need to replace the entire connecting plate, thus reducing the maintenance cost of modification errors.

[0022] In some embodiments of this application, the first connector is provided with a threaded hole for threaded connection with the bolts used to fix the mounting component.

[0023] In this technical solution, during later modifications or repairs, there is no need to customize special connectors. Standard bolts and wrenches can be directly adapted to the threaded holes of the first connector, avoiding the problems of difficult procurement and high cost of special parts. When replacing damaged bolts, the procurement cycle is shortened compared to special connection methods such as clips and rivets. The non-removable nature of welding, the easily damaged parts during disassembly of glued connections, and the need to destroy the hole for rivet disassembly, threaded connections can be disassembled and assembled by rotation without damaging the first connector, connecting plate, and additional parts.

[0024] In some embodiments of this application, the connecting plate is provided with a groove, and the groove is coated with structural adhesive for connection with the outer plate.

[0025] In this technical solution, the recessed structure of the groove allows the structural adhesive to form an embedded bond with the connecting plate. After the adhesive layer fills the groove, the bonding contact area increases compared to single-sided bonding with flat adhesive. The embedded structure resists the peeling forces generated by vibrations during vehicle operation, preventing the adhesive layer from detaching from the connecting plate surface and extending the bond life.

[0026] In some embodiments of this application, the outer panel has a flange at its edge, which is used to snap on the sealing strip and connect to the connecting plate.

[0027] In the technical solution, the sealing strip of the flange snap-fit ​​achieves waterproof and dustproof protection, forming a seal at the connection gap between the flange and the connecting plate. When the flange and the connecting plate are connected, the sealing strip can fill the gap between the two, preventing moisture from seeping in through the connection hole; the elasticity of the sealing strip can buffer the vibration transmission between the flange and the connecting plate, reduce the abnormal noise generated by the rigid metal contact, and reduce the overall vibration noise of the door.

[0028] In a second aspect, this application provides a vehicle, including: a body and a door as described in the first aspect, the door being disposed on the body.

[0029] In this technical solution, the second connection hole is only opened during modification, with no exposed brackets, nuts, or other connecting parts, ensuring that the vehicle's appearance is consistent with the unmodified vehicle and meeting users' demand for a clean, original look. Alternatively, the second connection hole can be pre-drilled in the outer panel and concealed through process design, such as aligning the hole with the fold lines or grooves of the outer panel's stamped shape, making it visually inconspicuous. Alternatively, a removable decorative cover of the same color as the outer panel can be used to cover the hole at the factory. During later modifications, the added parts are fixed to the inner first connecting part via the second connecting part, or the added parts are directly fixed to the first connection hole using bolts or clips. The added parts fit snugly against the outer panel surface, and the head of the second connecting part can be hidden inside the added part, avoiding the problem of exposed modified parts disrupting the overall vehicle design style, as is common in existing technologies.

[0030] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0034] 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. It should be noted that in the automotive field, in the modern automotive industry, off-road vehicles not only meet daily travel needs, but also become an important vehicle for consumers to pursue outdoor fun and realize personalized expression. As a key component of the appearance and function of off-road vehicles, reasonable door modification and reserved structure design has become an important part of meeting the diversified needs of users.

[0035] Currently, the mainstream technical solution for door modification in the industry is to directly install decorative parts on the exterior sheet metal surface of the door, pre-setting interfaces for later modifications. This technical approach exposes the necessary connecting components on the door surface, providing a foundation for subsequent modifications and satisfying some modification needs to a certain extent. This has become the door modification pre-installation method adopted by most automakers at present.

[0036] However, the existing technical solutions have the following drawbacks: First, directly installing decorative parts on the exterior door sheet metal destroys the original simple and elegant appearance of the door, resulting in a mismatch between the door and the overall vehicle design style before modification, affecting the overall aesthetics of the vehicle; Second, the connection structure between the exposed decorative parts and the door sheet metal is prone to vibration transmission during vehicle operation, damaging the original acoustic and vibration characteristics of the door, reducing the vehicle's NVH (vibration, noise, and harshness) performance, and affecting the ride comfort of passengers; Third, due to the lack of reasonable space for modification structure and load-bearing reinforcement design, large-scale adjustments to the door sheet metal are required during later modifications, which not only makes the modification process complex and cumbersome, increasing modification costs and time costs, but also easily leads to insufficient rigidity and strength of the modified door, causing additional vibration and noise problems.

[0037] This application proposes a car door and a vehicle. The car door includes an outer panel and a connecting plate. A second connecting hole is formed in the outer panel. An add-on is disposed on the second side of the outer panel and has a third connecting hole. The connecting plate is disposed on the first side of the outer panel and has a first connecting hole. A first connecting member is fixed to the connecting plate on the side away from the outer panel or on the first side of the outer panel. A second connecting member passes through the third connecting hole, the second connecting hole, and the first connecting hole in sequence and then connects with the first connecting member. This achieves the technical effect of a simple and harmonious appearance of the outer panel before modification, no need for large-scale adjustment of the outer panel sheet metal during modification, and sufficient structural strength and optimized NVH performance after modification. It solves the problems of the prior art where directly installing decorative parts on the outer panel of the car door results in an uncoordinated appearance, exposed connecting structures damage NVH performance, and large-scale processing of the outer panel is required for later modification, resulting in insufficient rigidity after modification.

[0038] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0039] As attached Figures 1 to 5 As shown, in a first aspect, this application provides a vehicle door, including an outer panel 1 and a second connecting hole 11 formed on the outer panel 1. At least one second connecting hole 11 is provided for connection with an add-on component 2. The second connecting hole 11 is not drilled at the vehicle's factory; it is only drilled when the user requires it, ensuring a clean and flat appearance for the outer panel 1, consistent with the overall vehicle design style. This solves the problem of cluttered appearance caused by directly adding decorative parts to the exterior sheet metal in existing technologies.

[0040] In some embodiments, the two sides of the outer panel 1 are respectively the first side and the second side, the second side is usually the exterior surface, and the first side is usually the non-exterior surface. The add-on 2 is disposed on the second side of the outer panel 1, the connecting plate 3 is disposed on the first side of the outer panel 1, and the first connecting member 4 and the first connecting hole 31 are both located on the non-exterior surface of the outer panel 1. The exterior surface of the outer panel 1 when the vehicle leaves the factory has no pre-installed exposed decorative parts. The second connecting hole 11 is only opened when the add-on 2 needs to be installed, so that the appearance of the outer panel 1 is simple and flat, and consistent with the overall vehicle design style.

[0041] In some embodiments, the door further includes a connecting plate 3 and a first connecting hole 31 opened on the connecting plate 3. The connecting plate 3 is disposed on the first side of the outer panel 1 and is fixedly connected to the outer panel 1. The connecting plate 3 can improve the strength of the outer panel 1 and prevent the outer panel 1 from vibrating, thereby improving NVH performance.

[0042] Through the above solution, the connecting plate 3 can disperse the vibration stress of the outer plate 1 during driving and avoid the outer plate 1 from generating high-frequency vibration due to insufficient rigidity. This solution has no exposed connecting structure, such as the external bracket and protrusion 32 buckle of the prior art, which can reduce the wind noise generated by the airflow impacting the exposed structure during driving, as well as the collision noise between the exposed structure and the outer plate 1 during vibration.

[0043] In some embodiments, the first connecting hole 31 is pre-threaded, and when the mounting part 2 is installed later, the mounting part 2 is fixedly connected by bolts engaging with the threads on the first connecting hole 31.

[0044] In some embodiments, the connecting plate 3 includes a reinforcing portion 34, which increases the strength of the outer plate 1. The reinforcing portion 34 enhances the overall strength of the outer plate 1 by covering key stress areas on the non-exterior surfaces of the outer plate 1, thus compensating for insufficient rigidity of the outer plate 1 itself. For off-road vehicles frequently encountering bumps and impacts, it reduces high-frequency deformation of the outer plate 1 caused by vibration, avoiding the problem of localized dents in the outer plate 1 caused by relying solely on the connecting structure for load-bearing.

[0045] In some embodiments, the connecting plate 3 includes a connecting portion 35, which is integrally formed with the reinforcing portion 34. The connecting portion 35 is located on the side of the connecting plate 3 corresponding to the mounting part 2. The first connecting hole 31 is formed on the connecting portion 35. The connecting portion 35 is provided with a first connecting hole 31 corresponding to the mounting part 2 for connecting the mounting part 2. By integrally forming the connecting portion 35 with the reinforcing portion 34, the load of the mounting part 2 is directly transferred to the reinforcing portion 34, optimizing the force transmission path, avoiding force concentration, and solving the problems of assembly gap and force transmission breakage caused by the separation of the traditional reinforcing part and connecting part.

[0046] In some embodiments, the mounting component 2 in the door is located on the second side of the outer panel 1; the mounting component 2 is provided with at least one third connection hole 21, through which the mounting component 2 can be fixed to the outer panel 1.

[0047] In some embodiments, the door further includes a first connector 4 and a second connector 5. The first connector 4 is disposed on the connecting plate 3, or between the connecting plate 3 and the outer plate 1. When it is necessary to fix the add-on 2, the second connector 5 passes through the third connecting hole 21, the second connecting hole 11, and the first connecting hole 31 in sequence, and connects with the first connector 4, thereby fixing the add-on 2 to the outer plate 1. When it is not necessary to fix the add-on 2, the second connector 5 is simply fixed to the vehicle as an accessory. When installing the add-on 2, the through-fixing allows the add-on 2 to form a rigid whole with the outer plate 1 and the connecting plate 3. Even if the add-on 2 is installed later, there will be no vibration or noise due to loose connection, thus optimizing NVH performance structurally.

[0048] In some embodiments, the connecting plate 3 has a pre-set first connecting hole 31 with a thread. The second connecting member 5 is a bolt, and the bolt and the first connecting hole 31 are connected by a threaded engagement, without the need for a connection via the first connecting member 4. The connecting plate 3 is located on the first side of the outer plate 1, an area that is typically narrow. If a bare hole design were used, a nut would need to be added to the other side of the connecting plate 3 to secure the bolt. The threaded first connecting hole 31 eliminates the need for an additional nut; the bolt can simply be passed through the mounting member 2, the outer plate 1, and the connecting plate 3 from the second side of the outer plate 1 and tightened directly into the threaded connecting hole. No special tools are required, solving the assembly difficulties caused by the narrow space on the non-exterior surfaces and lowering the operational threshold for users to perform later modifications.

[0049] In some embodiments, the second connecting hole 11, the third connecting hole 21, and the first connecting hole 31 are coaxially arranged. The coaxial arrangement of the three holes allows the axis of the second connector 5 to coincide with the axis of the three holes, and the connector can smoothly pass through the add-on 2, the outer plate 1, and the connecting plate 3 along the same axis without the need for additional hole alignment adjustments. This reduces the complexity of the modification operation, shortens the assembly time, and solves the problem of complex and cumbersome modification processes in the prior art.

[0050] In some embodiments, the second connecting hole 11 is configured as an oblong hole, which provides position adjustment margin for the installation of the mounting component 2. The second connecting hole 11 is formed on the outer plate 1, and the second connector 5 passes through the outer plate 1 and the connecting plate 3. When the second connecting hole 11 is configured as an oblong hole, the short axis dimension of the oblong hole is adapted to the outer diameter of the second connector 5, ensuring that there is no significant shaking in the short axis direction after the connector is inserted, thus ensuring connection stability. The long axis dimension is larger than the short axis dimension, providing displacement adjustment space along the long axis direction. The long axis direction of the oblong hole can be designed according to the force characteristics of the outer plate 1 and the adjustment requirements of the mounting component 2, without compromising the overall structural strength of the outer plate 1, and can solve installation problems in assembly and modification through adjustment space.

[0051] In some embodiments, the contact surface of the first connecting hole 31 on the connecting plate 3 protrudes 32 on the side away from the outer plate 1 to improve the connection strength. The connecting plate 3 is the load-bearing area of ​​the modified structure and needs to bear the weight of the added component 2 and the vibration load during vehicle operation. If the area of ​​the connecting plate 3 corresponding to the first connecting hole 31 is a plane, the stiffness of this area depends only on the thickness of the connecting plate 3 itself, and it is prone to bending or shear deformation under load. The structure protruding 32 on the side away from the outer plate 1, as described above, is equivalent to forming a local reinforcing boss at the position of the connecting plate 3 corresponding to the first connecting hole 31. The boss makes the effective thickness of this area greater than that of other areas of the connecting plate 3, thereby improving the local stiffness.

[0052] In some embodiments, the first connector is located on the side of the connecting plate away from the outer plate. The first connector 4 is disposed on the protrusion 32 structure. The reinforced design of the protrusion 32 allows the connecting plate 3 to more stably bear the tensile force and lateral shear force transmitted by the second connector 5, avoiding the connection plate 3 from breaking or failing due to insufficient rigidity, and solving the problem of insufficient load-bearing capacity after modification in the prior art.

[0053] In some embodiments, when the first connector 4 is set as a connecting part 35, the assembly tolerance between the outer plate 1 and the connecting plate 3 can be compensated by the connector between the outer plate 1 and the connecting plate 3, without the need for high machining accuracy of the connecting plate 3, thus reducing production costs. When the add-on 2 is installed, if the thread of the first connecting hole 31 is damaged due to misoperation, it can be repaired by the first connector 4 on the protrusion 32, without the need to replace the entire connecting plate 3, thus reducing the maintenance cost of modification errors.

[0054] In some embodiments, the connecting plate 3 is provided with a groove 33, which can improve the strength of the connecting plate 3. The groove is coated with structural adhesive for connection with the outer plate.

[0055] In some embodiments, the groove 33 and the connecting plate 3 are integrally formed, such as by pressing the groove 33 directly onto the connecting plate 3 using a stamping die, without any splicing gaps or connecting welds, ensuring that the groove 33 and the connecting plate 3 form a rigid whole, and that force can be directly transmitted to the main body of the connecting plate 3 through the groove 33, without stress concentration due to loose connection.

[0056] Through the above scheme, the recessed structure of groove 33 enables the structural adhesive to form an embedded bond with the connecting plate 3. After the adhesive layer fills the groove 33, the bonding contact area increases compared to single-sided bonding with flat adhesive. The embedded structure can resist the peeling force generated by vibration during vehicle operation, preventing the adhesive layer from falling off the surface of the connecting plate 3 and extending the bonding life.

[0057] In some embodiments, the grooves 33 are provided in at least two rows, and the first connecting hole 31 is located between the two rows of grooves; through the structural support and force transmission reinforcement effect formed by the grooves 33 on both sides, the stress borne by the first connecting hole 31 can be dispersed, thereby enhancing its connection strength.

[0058] In some embodiments, the outer panel 1 has a flange 12 at its edge, which is used to snap a sealing strip and connect to the connecting plate 3. The sealing strip snapped by the flange 12 provides waterproofing and dustproofing, forming a seal at the connection gap between the flange 12 and the connecting plate 3. When the flange 12 is connected to the connecting plate 3, the sealing strip can fill the gap between them, preventing moisture from seeping in through the connection hole; the elasticity of the sealing strip can buffer the vibration transmission between the flange 12 and the connecting plate 3, reducing abnormal noise generated by rigid metal contact, and reducing the overall vibration noise of the door.

[0059] In some embodiments, the first connector 4 is provided with a threaded hole for threaded connection with the bolts fixing the mounting part 2. During later modifications or repairs, there is no need to customize special connectors; standard bolts and wrenches can be directly adapted to the threaded hole of the first connector 4, avoiding the problems of difficult procurement and high cost of special parts. When replacing damaged bolts, the procurement cycle is shortened compared to special connection methods such as clips and rivets. The non-removable nature of welding, the easily damaged parts during disassembly of glued connections, and the need to destroy holes for rivet disassembly, all benefit from threaded connections, which can be disassembled and assembled simply by rotation without damaging the first connector 4, the connecting plate 3, and the mounting part 2.

[0060] In some embodiments, to prevent loosening of the threaded connection due to vehicle vibration and resulting in poor NVH performance, conventional anti-loosening measures in the automotive field can be adapted at the threaded mating points. The bolts use fine threads to improve thread self-locking, or thread-locking adhesive can be applied; all anti-loosening designs do not add additional protrusions 32 to the outer surface of the outer plate 1, conforming to the design of concealed connections.

[0061] With the above solution, if the additional component 2 needs to be replaced later, the old additional component 2 can be removed simply by unscrewing the bolts from the outside of the additional component 2, without damaging the second connecting hole 11 of the outer plate 1 and the structure of the connecting plate 3. This allows for multiple modifications and reuse of the reserved structure, improving the flexibility of modification and avoiding the limitations of one-time modification in existing technologies.

[0062] In some embodiments, the first connector 4 is configured as two nuts, which are sequentially screwed onto the bolt along the axial direction, and the friction generated by the preload between the two nuts prevents the threads from loosening.

[0063] Through the above solution, the structure of the two nuts forms an anti-loosening structure through the static friction generated by the preload between the nuts. After the two nuts are axially tightened, the static friction of the threaded contact surface is greater than that of a single nut, which can resist the tendency of the threads to rotate relative to each other due to vibration. Even when the vehicle is subjected to high-frequency bumps, the threaded connection between the bolt and the double nuts is not prone to loosening, avoiding the shaking and abnormal noise of the added component 2, improving the NVH performance of the door, and enhancing the comfort of the ride.

[0064] In addition, the contact area of ​​the first nut can distribute the preload pressure and prevent local dents in the connecting plate 3; the double nuts provide more stable axial positioning of the bolts, and there will be no radial offset when the bolts penetrate the three-layer structure, ensuring that the load of the added part 2 is evenly transmitted to the double nuts through the bolts and then distributed to the connecting plate 3. The double nuts and the groove 33 and protrusion 32 structure of the connecting plate 3 can jointly improve the overall connection strength.

[0065] In some embodiments, the first connector 4 is located on the side of the connecting plate 3 away from the outer plate 1. The first connector 4 is located on the back of the connecting plate 3 inside the outer plate 1, not exposed on the second side of the outer plate 1, and does not occupy the fitting space between the outer plate 1 and the connecting plate 3. When the vehicle leaves the factory without modification, only the second connecting hole 11 needs to be reserved on the outer surface of the outer plate 1. The second connecting hole 11 can be hidden through process design, such as to match the shape lines of the outer plate 1, or when decorative parts need to be added. The second side of the outer plate 1 has no connectors or fixing structures with protrusions 32, and the surface of the outer plate 1 is simple and flat, consistent with the overall vehicle design style. When the add-on 2 is installed later, the first connector 4 is hidden inside, and the head of the second connector 5 can be hidden on the surface of the add-on 2, avoiding the problem of exposed connectors damaging the appearance in the prior art.

[0066] In some embodiments, the door also includes a frame that supports the overall structure of the door and has a certain degree of rigidity. The load of the added component 2 is transferred to the connecting plate 3 through the second connector 5, and then distributed by the connecting plate 3 to the reinforcing beam of the frame, rather than just to the outer panel 1, thus preventing the outer panel 1 from denting or deforming due to excessive local stress. Even if heavier components are added, such as the anti-scratch guard plate of an off-road vehicle door, it will not cause abnormal noise when opening and closing the door or structural deformation after long-term use, solving the problem of insufficient door strength after modification in the prior art. When not modified, the second connecting hole 11 can be hidden through process design, or the second connecting hole can only be opened when modification is required, improving the cleanliness of the door's appearance.

[0067] In addition, the rigid system formed by the frame and the connecting plate 3 can absorb some high-frequency vibrations, prevent the outer plate 1 from producing abnormal noises due to vibration, and improve the vehicle's NVH performance and driving comfort.

[0068] A second aspect of this application provides a vehicle, including a body and a door as described in the first aspect, wherein the door is disposed on the body.

[0069] The above solutions involve opening the second connection hole 11 only during modification, without exposing brackets, nuts, or other connecting parts, ensuring that the vehicle's appearance is consistent with the unmodified vehicle and meeting the user's demand for a clean, original look. Alternatively, the second connection hole 11 can be pre-reserved on the outer panel 1 and concealed through process design, such as aligning the hole with the fold lines or grooves of the outer panel 1's stamping shape, making it visually inconspicuous. At the factory, a removable decorative cover of the same color as the outer panel 1 can be used to cover the hole. During later modifications, the add-on 2 is fixed to the inner first connect-on 4 via the second connect-on 5, or the add-on 2 is directly fixed to the first connection hole via bolts or clips. The add-on 2 fits against the surface of the outer panel 1, and the head of the second connect-on 5 can be hidden inside the add-on 2, avoiding the problem of exposed modified parts disrupting the overall vehicle design style, specifically preventing the external roof rack bracket protrusion 32 from causing cluttered body lines.

[0070] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
