[0028] The embodiments of the present application will be described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application will be described in detail below.

[0029] The embodiments of the present application will be described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application will be described in detail below. Figures 1-5 The tailgate assembly 100 according to the embodiment of the present application is described below with reference to

[0030] Referring to Figures 1-5 , the tailgate assembly 100 according to the embodiment of the present application comprises: a tailgate inner plate 11, a mounting plate 12 and at least three functional accessories 13.

[0031] The rear door inner panel 11 is a part of the interior of the vehicle trunk door, usually made of plastic, metal or composite material, and is installed on the inner side of the rear door of the vehicle. The mounting plate 12 is fixed on the rear door inner panel 11, and at least three functional accessories 13 are arranged at intervals and are fixed on the mounting plate 12. In this way, the plurality of functional accessories 13 are integrated on the same mounting plate 12, compared with the scheme that the plurality of functional accessories 13 are installed on different mounting plates 12, the number of mounting plates 12 to be made is reduced, the part tolerance accumulation can be reduced, the dimension chain is shortened, and the mounting precision of the rear door is improved.

[0032] In addition, the plurality of functional accessories 13 are separately made mounting plates 12, the process is complex, and more molds are required. Only one mounting plate 12 can reduce the manufacturing process, reduce the development cost of molds and tooling, and after the number of parts is reduced, the weight is also reduced, and the lightweight of the rear door assembly 100 is realized.

[0033] Referring to Figures 1-3 As shown in the figure, the at least three functional accessories 13 are arranged in a triangular shape on the mounting plate 12. The triangle is one of the relatively stable geometric shapes, and the triangular layout of the functional accessories 13 can effectively disperse the load, so that each support point bears a certain load without being excessively concentrated on a certain point. In this way, when the functional accessories 13 bear external forces such as torque and vibration, the deformation is small, and the accurate position of the functional accessories 13 can be maintained, and the deformation is better resisted.

[0034] In addition, the functional accessories 13 are arranged in a triangular shape, the space on the mounting plate 12 can be fully utilized, the mutual interference between the plurality of functional accessories 13 is avoided, and the compactness and functionality of the overall layout are improved.

[0035] Therefore, by integrating the plurality of functional accessories 13 on the same mounting plate 12, the part tolerance accumulation can be reduced, the dimension chain is shortened, and the mounting precision of the rear door is improved. At the same time, the manufacturing process is reduced, the development cost of molds and tooling is reduced, and the weight of the rear door assembly 100 is reduced.

[0036] Referring to Figures 1-3 As shown in the figure, the center of gravity lines of the at least three functional accessories 13 form a triangle on the mounting plate 12. In structural mechanics analysis, the triangular layout simplifies calculation and analysis. Due to its fixed angle and constraint condition, the structure of the triangle is convenient for statics analysis, and the transmission and distribution of force can be more clearly analyzed, and the design and process are optimized. In the embodiment of the utility model, the functional accessories 13 are three, the three functional accessories 13 are arranged in a "left-middle-right" triangular shape, preferably, the fixed positions of the three functional accessories 13 are arranged in an acute angle triangular shape, the center of gravity lines of the functional accessories 13 form a triangle on the mounting plate 12, and the stability of the rear door assembly 100 is improved.

[0037] Further, the center of gravity of the mounting plate 12 and the at least three functional accessories 13 is symmetrical about the plane formed by the width direction and the height direction of the vehicle. That is, the center of gravity of the tail door assembly 100 after calculation of the three functional accessories 13 is symmetrical about the left and right of the vehicle body XZ plane, which ensures that the tail door does not deviate from the center of gravity, and makes the opening and closing force of the tail door symmetrical and uniform. Therefore, when the tail door is used for a long time, the shaking of the functional accessories 13 can be reduced, that is, the problem of tail shaking can be avoided, and the NVH mode and stability of the tail door assembly 100 can be ensured.

[0038] It should be noted that the vehicle body XZ plane refers to a plane used in the design and analysis of the vehicle in a three-dimensional coordinate system. In vehicle engineering, the X axis usually represents the front-rear direction of the vehicle along the length, the Y axis usually represents the left-right direction of the vehicle along the width, and the Z axis usually represents the up-down direction of the vehicle along the height. Among them, the XZ plane refers to the plane composed of the X axis and the Z axis, which is perpendicular to the Y axis.

[0039] Referring to Figure 4 As shown in the figure, the mounting plate 12 is provided with at least three first mounting parts, and the functional accessories 13 are provided with second mounting parts 131. The at least three first mounting parts are connected with the second mounting parts 131 of the at least three functional accessories 13, respectively. In this way, the first mounting part and the second mounting part 131 can be used to integrate the multiple functional accessories 13 on the mounting plate 12.

[0040] Among them, the first mounting part includes at least three first mounting holes 121, and the at least three first mounting holes 121 are arranged in a triangular shape. That is, each functional accessory 13 has at least three mounting points on the mounting plate 12. In the embodiment of the utility model, the first mounting part includes three first mounting holes 121, which can ensure that the first mounting part is more stable and avoid shaking of the functional accessories 13 during opening and closing of the tail door, which may cause interference and abnormal noise.

[0041] Further, the mounting plate 12 is arranged on the side of the tail door inner panel 11 facing the vehicle interior, and a cavity is formed between the mounting plate 12 and the tail door inner panel 11. On the one hand, the cavity can act as a sound insulation layer to reduce noise transmitted from other components. The cavity formed between the mounting plate 12 and the tail door inner panel 11 can increase the distance between the mounting plate 12 and the tail door outer panel. The cavity can effectively absorb and isolate the vibration of the tail door, reduce the transmission of vibration to other components of the vehicle body, and reduce the risk of interference and abnormal noise caused by the functional accessories 13.

[0042] On the other hand, through the design of the cavity, a reinforced structure can be formed between the tailgate inner panel 11 and the mounting plate 12, providing better impact and collision resistance, helping to improve the rigidity of the vehicle body, making the tailgate less likely to deform when subjected to external impact, and improving overall safety. Moreover, without sacrificing strength, the use of materials can be reduced, thereby reducing the overall weight of the vehicle. Reducing the weight of the vehicle not only helps to improve the fuel efficiency and performance of the vehicle, but also reduces transportation costs.

[0043] The mounting plate 12 and the tailgate inner panel 11 are welded together. The welding connection can improve the structural strength and rigidity of the mounting plate 12. The welding can ensure that the mounting plate 12 and the tailgate inner panel 11 are tightly combined, avoiding problems such as loosening or deformation at the connection. This can improve the overall rigidity and strength of the tailgate, better protecting the internal structure and personnel safety when the vehicle is subjected to external impact, such as collision, jolt, etc.

[0044] Welding connection makes the combination between the mounting plate 12 and the tailgate inner panel 11 more tightly and stably, reducing the risk of loosening, breaking or structural fatigue. Especially when the vehicle is subjected to long-term use and vibration, welding connection can effectively prevent loosening or falling off at the connection point, thereby ensuring the safety and durability of the vehicle body.

[0045] During manufacturing, welding is a highly automated process that can improve production efficiency and reduce the complexity of manual operations. By welding the mounting plate 12 and the tailgate inner panel 11, the entire production process can be simplified, reducing reliance on other connection methods such as bolts, rivets, etc., reducing assembly time and cost. In addition, welding connection usually has high precision, which can reduce adjustment or rework caused by loose connection, and the welding point usually has long durability, which can reduce maintenance frequency and maintenance cost.

[0046] Moreover, welding connection usually requires less additional material than other methods such as bolt connection or riveting, which not only reduces material cost, but also makes the design more compact and lightweight, helping to improve the fuel efficiency and performance of the vehicle. Compared with bolts or rivets, welding can better hide the connection points, reduce exposed parts, and improve the overall aerodynamic design of the vehicle body.

[0047] In addition, the tailgate assembly 100 can also include a fastener, the mounting plate 12 is provided with a second mounting hole, and the tailgate inner panel 11 is provided with a third mounting hole, and the fastener connects the second mounting hole and the third mounting hole. That is, the tailgate inner panel 11 and the mounting plate 12 can also be fixed by passing the fastener through the second mounting hole and the third mounting hole.

[0048] Fastener connection can be easily disassembled during maintenance or replacement without damaging the connection point, making maintenance more convenient. Fastener connection can also adapt to complex geometries, especially in areas where welding operations are difficult. When using fasteners, engineers can precisely control the fastening force of the connection through a standardized torque tightening tool, ensuring uniformity and firmness of the connection, avoiding over-tightening or loosening, and ensuring the stability and safety of the structure.

[0049] Furthermore, fastener connection can effectively reduce stress concentration by evenly distributing the force of the connection points, helping to improve the durability of the connection site. In the event of external force impact, fastener connection can better disperse stress and avoid local deformation or damage. At the same time, fasteners have lower cost and weight, meeting the lightweighting needs of vehicles. It is suitable for mass production and assembly.

[0050] Among them, the fastener can be a bolt, nut, etc.

[0051] Further, the functional accessory 13 is one or more of an electric curtain motor, a wiper motor, and a shock absorber. The electric curtain motor is used to automatically control the opening and closing of the curtain, so that the opening and closing of the curtain no longer needs to be manually pulled, but is controlled through remote control, switches, or even smart devices. The electric curtain motor mainly consists of a motor body, a speed reducer, a limit switch, a control circuit, and a sensor.

[0052] The wiper motor is the core component of the wiper system, used to drive the wiper arm to keep the windshield clean. It is driven by electricity to remove rain, snow, and dust, ensuring the driver's clear vision in adverse weather conditions. It mainly includes a motor body, brushes, and a commutator.

[0053] The shock absorber, also known as a shock absorber, is an important part of the automobile suspension system, used to absorb and reduce the shock from uneven road surfaces or impacts, ensuring the stability and comfort of vehicle driving. The shock absorber absorbs and dissipates the impact force between the wheels and the ground, reducing the up-and-down movement of the vehicle, making the vehicle body movement more stable. This helps improve comfort during driving, adjusts the spring response, and makes the suspension system better respond to different road conditions, avoiding excessive swinging and body tilting, enhancing vehicle handling, reducing accident risk, prolonging the service life of the vehicle, and improving comfort.

[0054] Specifically, in this embodiment, the electric curtain motor, wiper motor, and shock absorber are integrated on the mounting plate 12. Compared with the separate design of the three components, about 6 to 7 process steps can be reduced, and the tooling development cost of the mold can be reduced by 300 to 400 thousand yuan. This effectively improves the precision of the rear door assembly 100, reduces development costs, achieves lightweighting, and improves vehicle body stability.

[0055] Referring toFigures 2-4 As shown, the mounting plate 12 is provided with a relief hole 14 corresponding to the wiper motor. In the prior art, the reinforcing plate of the wiper motor is designed between the rear door inner panel 11 and the rear door outer panel. On the one hand, in order to match the rear door inner panel 11 and the mounting structure of the wiper motor, the rear door inner panel 11 needs to be provided with a hole in the same direction as the reinforcing plate of the wiper motor, which may cause the rear door inner panel 11 to increase by one or more punching processes, and the development cost of the mold tooling is increased by about 500 to 600 thousand yuan. On the other hand, the rear door inner panel 11 needs to be provided with a corresponding feature rib to match the reinforcing plate of the wiper motor. Because the punching depth of some areas is the highest, the increase of the feature rib causes the plate material to increase the stretching amount, which increases the risk of forming cracking and is not conducive to the formability.

[0056] Therefore, in the embodiment, the mounting plate 12 is designed at the front side of the rear door inner panel 11. By providing the relief hole 14, the wiper motor is avoided, and the mounting points of the electric curtain motor, the wiper motor and the shock absorber can be designed according to the structure itself, without the need to open mounting holes on the rear door inner panel 11, thereby reducing the problem of increasing the punching process of the large rear door inner panel 11, and reducing the development cost of the mold tooling by 500 to 600 thousand yuan. At the same time, the mounting points of the electric curtain motor, the wiper motor and the shock absorber are fixed on the mounting plate 12 by fasteners, and the distance from the rear door outer panel can be adjusted to reduce the risk of interference and abnormal sound.

[0057] On the other hand, the feature rib does not need to be increased, and the risk of forming cracking is reduced.

[0058] In addition, the mounting plate 12 is arranged at the front side of the rear door inner panel 11, which can be designed as a black paint movable component, and can realize integration with the electric curtain motor, the wiper motor and the shock absorber after mounting to form a small assembly unit on the assembly line body, thereby improving the efficiency and production rhythm.
