[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] In the related art, the installation wiring harness of the vehicle tailgate needs to be arranged between the outer panel and the inner panel of the rear door assembly, and a reinforcement plate is provided on the inner panel to strengthen the overall structure of the rear door assembly. When assembling the tailgate installation wiring harness, a wiring harness assembly part is required. The installation wiring harness is provided on the wiring harness assembly part. The wiring harness assembly part drives the wiring harness through the installation space between the inner and outer panels, but the wiring harness assembly part and the connectors of the installation wiring harness often hang on the edge of the reinforcement plate, causing the wiring harness assembly to become stuck, which brings difficulties to the assembly of the installation wiring harness and seriously affects the assembly efficiency.

[0028] Reference below Figure 1-Figure 2 A rear door panel assembly according to an embodiment of the present invention is described.

[0029] According to the present invention, a rear door panel assembly 100 for a vehicle includes: an inner panel 12, an outer panel 11, a reinforcement plate and a wiring harness assembly 15, wherein the inner panel 12 and the outer panel 11 are respectively arranged on the vehicle body, and an installation space is formed between the inner panel 12 and the outer panel 11; a reinforcement plate, at least a portion of the reinforcement plate is connected to the inner panel 12, the reinforcement plate is accommodated in the installation space, and a protrusion protruding toward the outer panel 11 is formed at the edge of the reinforcement plate; the wiring harness assembly 15 is accommodated in the installation space, a wiring harness installation portion is formed on the wiring harness assembly 15, and an open opening for inserting and installing the wiring harness 14 is formed on the wiring harness installation portion; wherein the height of the protrusion is h1, the height of the open opening is h2, and satisfies: h1>h2.

[0030] In some specific embodiments, the rear door panel assembly 100 is composed of an inner panel 12, an outer panel 11, a reinforcing plate and a wiring harness assembly 15. The inner panel 12 and the outer panel 11 are respectively installed on the vehicle body. At least a portion of the inner panel 12 is spaced from at least a portion of the outer panel 11, and an installation space is formed between the two. At least a portion of the reinforcing plate is connected to the inner panel 12 by welding, and the reinforcing plate is accommodated in the installation space. The reinforcing plate can be used to enhance the overall structural strength and rigidity of the rear door panel assembly 100. A protrusion protruding toward the outer panel 11 is formed at the edge of the reinforcing plate. An opening is provided on the wiring harness assembly 15. Mouth, the installation wire harness 14 is inserted into the wire harness assembly 15 from the open mouth, the wire harness assembly 15 can drive the installation wire harness 14 to move in the installation space, the height of the raised portion is h1, the height of the open mouth is h2, and it satisfies: h1>h2. When the height of the raised portion and the height of the open mouth satisfy the above relationship, it can effectively prevent the wire harness or the wire harness assembly 15 from directly contacting the edge of the reinforcement plate, thereby avoiding the occurrence of jamming and ensuring that the wire harness can smoothly pass through the installation space. The optimized path allows the wire harness to be assembled more easily and quickly, thereby improving the assembly efficiency of the wire harness.

[0031] The rear door panel assembly 100 according to the present invention can effectively prevent the wiring harness or the wiring harness assembly 15 from directly contacting the edge of the reinforcement plate by setting the height h1 of the protruding portion and the height h2 of the opening within the range of h1>h2, thereby avoiding the occurrence of jamming and ensuring that the wiring harness can smoothly pass through the installation space. The optimized path allows the wiring harness to be assembled more easily and quickly, thereby improving the assembly efficiency of the wiring harness.

[0032] According to some embodiments of the present invention, the distance between the edge of the reinforcing plate and the inner plate 12 is L, and satisfies: 3.3mm≤L≤2.8mm. When the distance between the reinforcing plate and the inner plate 12 is set within the above range, it can not only ensure the flow of the electrophoresis liquid during electrophoresis and prevent the problem of poor electrophoresis, but also prevent the wiring harness from being stuck between the reinforcing plate and the inner plate 12 during assembly.

[0033] According to some embodiments of the present invention, the reinforcing plate includes: a reinforcing plate body 21 and a raised portion, one end of the reinforcing plate body 21 is connected to the inner plate 12, and the other end of the reinforcing plate body 21 extends toward the interior of the installation space; the raised portion is connected to the other end of the reinforcing plate body 21, and the raised portion is constructed as a trapezoid.

[0034] In some specific embodiments, the reinforcement plate is composed of a reinforcement plate itself and a raised portion. One end of the reinforcement plate body 21 is connected to the inner panel 12 by welding or other means. This connection ensures the stability and reliability of the reinforcement plate in the entire rear door panel assembly 100. The other end of the reinforcement plate body 21 starts from the inner panel 12 and gradually extends into the installation space. The raised portion is connected to the other end of the reinforcement plate body 21, and its shape is designed to be a trapezoid. The trapezoidal design allows the raised portion to have a certain height and can provide a smoothly transitioned inclined surface. Since the height of the raised portion is greater than the height of the open mouth of the wire harness assembly 15, when the wire harness assembly 15 drives the wire harness through the installation space, they will preferentially contact the inclined surface of the raised portion instead of directly touching the edge of the reinforcement plate, effectively avoiding the wire harness or the wire harness assembly 15 from hanging on the edge of the reinforcement plate, thereby ensuring the smooth assembly of the wire harness.

[0035] According to some embodiments of the present invention, the raised portion includes: a first extension section 22, a second extension section 23 and a third extension section 24, one end of the first extension section 22 is connected to the reinforcing plate body 21, and the first extension section 22 is inclined toward the reinforcing plate extension direction along the direction from the inner plate 12 to the outer plate 11; the second extension section 23 is connected to the other end of the first extension section 22, and the second extension section 23 extends toward the inside of the installation space; the third extension section 24 is arranged at one end of the second extension section 23 away from the first extension section 22, and the third extension section 24 is inclined along the direction from the inner plate 12 to the outer plate 11 The direction of the plate 11 is inclined toward the first extension section 22, and the angle between the first extension section 22 and the inner plate 12 is the same as the angle between the third extension section 24 and the inner plate 12, wherein the angle between the third extension section 24 and the inner plate 12 is α, and satisfies: 25°≤α≤30°, so that when the wire harness assembly 15 drives the wire harness to move, the resistance from the third extension section 24 and the first extension section 22 will not be too large, ensuring that the wire harness can slide smoothly along the first extension section 22 and the third extension section 24 during the assembly process without encountering any obstacles.

[0036] According to some embodiments of the present invention, the second extension section 23 is arranged parallel to the inner plate 12. The second extension section 23 is arranged parallel to the inner plate 12 to provide a flat and continuous surface for the wire harness or wire harness assembly 15, ensuring that they can move smoothly along this surface and reducing the possibility of encountering obstacles. Since the surface is flat, the friction is reduced to a minimum, allowing the wire harness to pass through the installation space more easily and avoiding jamming caused by excessive friction. The parallel setting helps to evenly distribute the pressure generated during the wire harness assembly process on the second extension section 23 to prevent damage caused by excessive local force.

[0037] According to some embodiments of the present invention, at least part of the reinforcing plate body 21 is formed with a reciprocating bending portion, the bending portion refers to a plurality of continuous bends or folds with alternating directions formed in a part of the reinforcing plate body 21, these bends can be regular waves, or can be designed into other irregular shapes according to specific needs, the bending portion does not necessarily cover the entire reinforcing plate body 21, but selectively appears in the part where specific performance needs to be enhanced, the bending portion increases the effective thickness of the reinforcing plate material, so that the reinforcing plate is not easy to be permanently deformed when subjected to external impact or pressure, and the overall mechanical strength is improved, the bending portion can more evenly distribute the force acting on it, avoid local stress concentration, and thus extend the service life, in some cases, the bending portion can also play a role in guiding the wire harness, helping the wire harness to be arranged along a predetermined path, and further reducing the risk of the wire harness being stuck. According to some embodiments of the present invention, the wire harness assembly 15 includes: a body and a hook, the body extending toward the inside of the installation space; the hook is connected to the body, an open mouth is formed on the hook, and the installation wire harness 14 is fixed on the hook.

[0038] In some specific embodiments, the wire harness assembly 15 is composed of a main body and a hook. The main body extends toward the inside of the installation space, which means that it starts from a relatively fixed point and goes deep into the inner space of the rear door panel. The main body plays a supporting and connecting role, providing a stable foundation for the hook and ensuring the correct position of the entire wire harness assembly 15 in the installation space. The hook is connected to the main body, and an open opening is formed on the hook. The installation wire harness 14 is inserted into the hook through the open opening and fixed on the hook, so that the wire harness assembly 15 drives the installation wire harness 14 to move in the installation space. This design of the wire harness assembly 15 makes the installation of the installation wire harness 14 more intuitive and simple, reducing assembly time and complexity.

[0039] According to some embodiments of the present invention, a reinforcing flange 25 is formed at the edge of the reinforcing plate. The reinforcing flange 25 improves the mechanical strength of the edge area of ​​the reinforcing plate by increasing the material thickness and changing the edge shape, thereby enhancing the structural rigidity and structural stability of the entire reinforcing plate and even the rear door panel assembly 100. The reinforcing flange 25 can effectively resist deformation under the action of external forces, ensure the shape accuracy of the reinforcing plate, and further ensure the correct fit between the reinforcing plate and the inner panel 12 or other components. The presence of the reinforcing flange 25 can extend the service life of the reinforcing plate and reduce the risk of damage caused by long-term use or external impact. The reinforcing flange 25 can also prevent the edge of the reinforcing plate from being too sharp during assembly, reducing the risk of injury to personnel, and also helps to protect other internal parts such as the installation harness 14 from damage.

[0040] According to some embodiments of the present invention, the reinforcing flange 25 is arranged parallel to the inner plate 12. The parallel arrangement helps the paint liquid to flow and adhere better during the electrophoretic coating process, prevents the generation of coating dead corners, and ensures the uniformity and integrity of the coating.
