[0040] In addition, if terms such as "first" and "second" appear, these terms are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] The embodiment of the present application provides an automotive front door trim panel assembly. The automotive front door trim panel assembly is installed on the upper part of the front door sheet metal of the vehicle. The water cut structure 1 of the front door upper trim panel assembly 1a is connected to the back surface of the front door structure skeleton 2 through a first connection assembly 3, and further through the first connection assembly 3 as a connection to improve the connection strength of the front door upper trim panel assembly 1a, and at the same time improve the assembly efficiency.

[0042] See Figures 1 to 6The automobile front door trim assembly includes a water-cutting mechanism, and the water-cutting structure 1 includes a main body section 106 arranged corresponding to one side of the window glass, and a connecting section 107 arranged relatively at the lower edge. It also includes a front door structure frame 2, which is connected to the connecting section 107 of the water-cut structure 1 via a first connecting component 3, and the first connecting component 3 is arranged along the length direction of the water-cut structure 1, and the first connecting component 3 has a first connecting portion 301, and the first connecting portion 301 is suitable for being clamped with the first connecting portion 301, so as to preliminarily locate the installation orientation of the water-cut structure 1 and the first connecting portion 301, and the first connecting component 3 simultaneously extends downward a plurality of second connecting portions 302 suitable for being connected to the front door structure frame 2, the front door structure frame 2 is provided with a skeleton docking portion 201 corresponding to the second connecting portion 302, and the water-cut structure 1 is provided with a water-cut docking portion 101 corresponding to the second connecting portion 302, the second connecting portion 302 is arranged between the skeleton docking portion 201 and the water-cut docking portion 101, and simultaneously penetrates the second connecting portion 302, the skeleton docking portion 201 and the water-cut docking portion 101 via the connecting member 12 to form a fixed connection.

[0043] In addition, sound-absorbing cotton 8 can be arranged between the upper trim assembly 1a and the door sheet metal. The arrangement of the sound-absorbing cotton 8 can absorb the noise from the outside that enters the vehicle compartment through the door during high-speed movement, thereby effectively preventing noise in the vehicle compartment.

[0044] Since the first connecting component 3 is arranged along the length direction of the water-cut structure 1, in order to ensure the structural strength of the first connecting component 3, a plurality of reinforcing ribs are provided on the inner side of the first connecting component 3. The plurality of reinforcing ribs are arranged along the width direction of the first connecting component 3. Furthermore, through the arrangement of the first connecting component 3, the overall structural strength of the first connecting component 3 can be further increased, thereby avoiding the occurrence of adverse situations such as breakage during installation due to the first connecting component 3 being arranged too long.

[0045] Therefore, by rationally designing the structural assembly of the front door upper trim assembly 1a, the water-cut structure 1 is connected to the front door structure frame 2 through the first connecting component 3, and the first connecting component 3 is arranged along the length direction of the water-cut structure 1. This layout helps to evenly disperse the connection stress and ensure the stability and reliability of the overall structural assembly.

[0046] In addition, the structural design can perform installation positioning more efficiently and accurately during installation. The first connecting component 3 is provided with a first connecting part 301 and can be snapped into the corresponding part to achieve the preliminary positioning of the installation orientation of the water-cut structure 1 and the first connecting part 301, which facilitates subsequent precise installation, improves assembly efficiency, and reduces installation deviations.

[0047] Meanwhile, since the first connection component 3 is used as the connecting piece 12 between the water cut-off structure 1 and the front door structure framework 2, the overall structure is more firmly and reliably installed and connected after assembly. Since the first connection component 3 extends downward to form multiple second connection parts 302, which respectively correspond to the framework docking part 201 of the front door structure framework 2 and the water cut-off docking part 101 of the water cut-off structure 1, the connecting piece 12 passes through all three parts to form a fixed connection at the same time. This multi-part and penetrating connection method greatly enhances the connection strength, ensures the firm connection between the water cut-off structure 1 and the front door structure framework 2, is not easy to loosen, and improves the overall structural strength and durability of the front door trim assembly of the vehicle.

[0048] Specifically, the water cut-off structure 1 is provided with a first clamping part 102 corresponding to the first connection part 301. The first connection part 301 is formed as a clamping groove, and the first clamping part 102 is adapted to be inserted into the clamping groove to initially position the water cut-off structure 1. Furthermore, through the cooperation between the clamping groove on the first connection part 301 and the first clamping part 102, the initial installation orientation of the water cut-off structure 1 can be accurately positioned during installation, and the assembly efficiency can be effectively improved.

[0049] More specifically, on the basis of the assembly and positioning of the first clamping part 102 and the clamping groove, a plurality of clamping openings 202 are further formed on the front door structure framework 2. The water cut-off structure 1 is provided with second clamping parts 105 corresponding to the clamping openings 202, and the second clamping parts 105 are adapted to be correspondingly inserted into the clamping openings 202 to further position the installation orientation of the water cut-off structure 1 and the front door structure framework 2. And through the clamping openings 202 formed on the front door structure framework 2 and the arrangement that the water cut-off structure 1 is provided with the second clamping parts 105 to be inserted into the clamping openings 202, in cooperation with the first clamping part 102, it is possible to ensure multi-point clamping to enhance stability; and through the cooperation between the clamping openings 202 and the second clamping parts 105, multi-point clamping fixation is formed between the water cut-off structure 1 and the front door framework, further improving the connection stability, reducing the assembly gap or shaking; and the clamping installation method can effectively improve the installation efficiency, and the clamping structure is convenient for quick alignment, reducing the time for manual adjustment and improving the production efficiency.

[0050] In addition, an end part of the water cut-off structure 1 extends downward to form a bending part 103, and a third clamping part 104 is provided on the bending part 103. The front door structure framework 2 is provided with a docking opening 203 corresponding to the third clamping part 104, and the third clamping part 104 is adapted to be inserted into the docking opening 203 to position the water cut-off structure 1 and the front door structure framework 2. Thus, the design of the bending part 103 enhances the rigidity of the end part of the water cut-off structure 1, and the cooperation between the third clamping part 104 and the docking opening 203 can prevent the end part from warping or deforming; through the cooperative action of the end part (bending part 103) clamping and the main body (unbent part 103) clamping, accurate positioning of the water cut-off structure 1 in multiple directions is realized.

[0051] In one embodiment, the water cut-off structure 1 is further provided with a plurality of mounting parts (not shown in the figure). The front door structure framework 2 is provided with framework docking parts 201 corresponding to the mounting parts. The framework docking parts 201 cover the mounting parts, and the connection parts and the mounting parts are fixed through the penetration of the connecting member 12. Preferably, the plurality of mounting parts and the docking parts are arranged at intervals along the length direction of the door sheet metal. And the water cut-off structure 1 is provided with mounting parts, the front door framework is provided with cover-type docking parts and fixed through the connecting member 12, which can take into account the aesthetics on the premise of ensuring the connection strength; in addition, since the docking parts cover the mounting parts, the connecting member 12 (such as bolts, screws, buckles and other connecting members capable of realizing fixed connection) can be hidden, the appearance cleanliness is improved, and at the same time, the contact area is increased to disperse the load and enhance the connection reliability. At the same time, the modular structure design is more flexible, and the standardized design of the mounting parts and the docking parts is convenient for the generalization and adaptation of the water cut-off structure 1 and other components.

[0052] In one embodiment, the front door trim assembly of the vehicle further includes a left front middle trim 4. The left front middle trim 4 is connected to the front door structure framework 2 via a connecting member 12. A left front middle trim air vent 9 is provided on the left front middle trim 4. An armrest mounting part 401 is further provided on the left front middle trim 4. A left front armrest assembly 5 is provided on the armrest mounting part 401. An installation through hole is provided on the left front armrest assembly 5. A left front emergency grab handle frame 6 is adapted to be arranged in the installation through hole. An installation position is provided on the front door structure framework 2. A left front CMS trim 7 is installed at the installation position and is installed on the front door structure framework 2 via a connecting member 12. In addition, an installation area for installing a left front middle speaker assembly is further provided on the left front middle trim 4. During installation, the left front middle speaker assembly is fixedly connected to the left front middle trim 4 via a connecting member 12. It should be noted that the connecting member 12 designed above can be a fixing connecting member 12 such as a screw or an anti-detachment buckle 202.

[0053] Specifically, the front door trim assembly of the vehicle includes a left front middle trim 4 and is connected via a connecting member 12, and is provided with an air vent. Integrating the air vent on the front middle trim can optimize the air circulation in the vehicle, reduce the cost of separate mold opening, and realize the modular integration and lightweight of functional components; and the fixing method of the connecting member 12 facilitates the quick disassembly and assembly of the middle trim, is convenient for maintenance or air vent cleaning, and improves the assembly convenience.

[0054] More specifically, the armrest mounting part 401 and the left front armrest assembly 5 of the left front middle trim 4 are optimized to improve the comfort and practicality in the vehicle by integrating the armrest assembly and meet the elbow support needs of passengers. At the same time, the structural strength is enhanced. The force of the armrest can be dispersed through the integrated design of the armrest mounting part 401 and the middle trim, avoiding local deformation caused by long-term use.

[0055] Moreover, a left front armrest assembly 5 is provided on an armrest mounting portion 401 provided on the left front middle trim panel 4. An installation through-hole is formed in the left front armrest assembly 5, and a left front emergency grab handle frame 6 is adapted to be disposed in the installation through-hole, so that the emergency grab handle frame and the middle trim panel are designed in coordination to ensure quick operation in case of emergency. At the same time, the compactness of the door interior layout is optimized, and the safety is improved. The connection strength between the grab handle frame and the skeleton is optimized to withstand emergency pulling force and avoid the risk of falling off.

[0056] More specifically, by providing an installation position on the front door structure skeleton 2 and snap-fixing it with the left front CMS trim strip 7, the reliability of the trim strip installation can be improved. The snap-fitting installation method enables quick pre-positioning. The secondary fixing of the connecting piece 12 (such as a screw) can prevent the left front CMS trim strip 7 from loosening or making abnormal noises, taking into account both the assembly efficiency and long-term durability. Moreover, the embedded installation design of the left front CMS trim strip 7 and the skeleton reduces the gap and improves the overall appearance quality of the door.

[0057] In one embodiment, referring to Figures 7 to 9 , the lower trim panel assembly 2a of the front car door includes a left front map pocket lower cover assembly 17 and a left front map pocket upper cover assembly 13. The left front map pocket lower cover assembly 17 and the left front map pocket upper cover assembly 13 enclose to form a map pocket chamber. A left front map pocket baffle 19 is further provided inside the map pocket chamber. The left front map pocket baffle 19 is fixedly installed inside the map pocket chamber via a second connecting component 24. A left front map pocket cushion block 21 is further provided at the bottom of the map pocket chamber. A left front door panel lower plug 22 is further provided at the bottom of the left front map pocket cushion block 21. Through the cooperation of the left front map pocket cushion block 21 and the left front door panel lower plug 22, the bottom of the map pocket chamber can be effectively supported, and at the same time, the bearing capacity of the map pocket is enhanced.

[0058] In addition, the setting of the second connecting component 24 can disperse local stress concentration and improve the anti-dent deformation ability, especially suitable for scenarios of carrying items or bearing lateral forces. In addition, the installation base 241 of the second connecting component 24 is designed to be inclined along the edge of the left front map pocket baffle 19, so as to change the force transmission direction (convert the vertical load into an inclined plane component force), reduce the risk of shear stress concentration at the connection point, and at the same time increase the contact area between the base and the baffle to improve the connection stability. Moreover, the mounting portion on the left front map pocket baffle 19 and the side of the installation base 241 are fixed by a connecting piece to form a lateral restraint structure. This design can effectively resist the torsional moment and prevent the baffle from loosening or displacing under long-term vibration or impact conditions, significantly improving the fatigue strength of the connection node.

[0059] Therefore, the front door lower trim assembly 2a of the automobile adopts a modular design, the left front map pocket lower cover assembly 17 and the left front map pocket upper cover assembly 13 are fixed by buckles and bolts to form a map pocket chamber, and the left front map pocket baffle 19 is preferably made of high-strength alloy material to further improve the structural strength of the left front map pocket baffle 19. At the same time, an anti-collision block 23 can be arranged between the left front map pocket lower cover assembly 17 and the left front map pocket upper cover assembly 13. The arrangement of the anti-collision block 23 can absorb energy through controllable deformation in a side collision, reduce the amount of door intrusion, and protect the integrity of the passenger compartment.

[0060] Specifically, a left front emergency buckle frame 15 is provided on the left front map pocket upper cover assembly 13, and the left front emergency buckle frame 15 is provided on the left front door emergency buckle assembly 14, and a left front armrest trim strip 16 is also provided on the side of the left front map pocket upper cover assembly 13. The lower end of the left front map pocket upper cover assembly 13 is connected to the left front map pocket lower cover assembly 17, so that the left front map pocket upper cover assembly 13 and the left front map pocket lower cover assembly 17 form an encirclement effect, and a left front lower guard plate assembly 18 is provided on its side, and the left front lower guard plate assembly 18 cooperates with the left front armrest trim strip 16 to jointly form a user-side contact protection structure. The left front map pocket upper cover assembly 13 adopts a modular integration solution, and the left front emergency buckle frame 15 is stamped on its surface, and this functional part realizes embedded assembly with the left front door emergency buckle assembly 14. The side wall of the left front map pocket upper cover assembly 13 is provided with a left front armrest trim strip 16 covered with three-dimensional fabric. The lower end is precisely engaged with the left front map pocket lower cover assembly 17 through double-row buckles to form a closed annular protection frame. At the lateral protection level, the left front lower guard plate assembly 18 is connected with the armrest trim strip to form a passenger body contact protection system.

[0061] Specifically, a left front map pocket assembly 20 is further provided inside the map pocket chamber, and the left front map pocket assembly 20 protrudes toward a side away from the map pocket chamber, so that the storage space of the formed map pocket chamber is larger. The left front map pocket assembly 20 is provided on the left front map pocket baffle 19, so that the side edge thereof is fixed by the left front map pocket baffle 19, so that the structural strength of the left front map pocket assembly 20 can be effectively improved.

[0062] In addition, in order to further improve the structural strength of the formed map pocket, the upper connecting end of the map pocket chamber is fixedly connected to the left front map pocket upper cover assembly 13, and the lower connecting end of the map pocket chamber is fixedly connected to the left front map pocket lower cover assembly 17, so as to achieve a comprehensive enhancement of the peripheral structural strength of the formed map pocket chamber.

[0063] In one embodiment, the second connection component 24 includes a mounting base 241 installed on a slope inside the left front map pocket baffle 19, and the map pocket baffle extends upward to form a mounting portion, and the mounting portion is fixedly connected to the side of the mounting base 241 via a connecting member.

[0064] Specifically, the mounting base 241 is adapted to mount the emergency handle assembly 25, and the mounting base 241 is provided with a plurality of alignment guiding structures 243. The emergency handle assembly 25 is provided with connection holes corresponding to the alignment guiding structures 243. The alignment guiding structures 243 are adapted to pass through the respective connection vacancies to position the emergency handle assembly 25. Thus, through the arrangement of the ramp-shaped mounting base 241, since it is provided with the alignment guiding structures 243, the alignment and guiding of the emergency handle assembly 25 provided thereon can be facilitated through the positioning guiding structures. Moreover, a plurality of linking holes are pre-opened on the emergency handle assembly 25, so that the rapid positioning and alignment of the emergency handle assembly 25 can be achieved, and the assembly accuracy of the device can be effectively improved.

[0065] In addition, an assembly connection portion 242 is further opened on the side of the mounting base 241 facing the map pocket cavity. The assembly connection portion 242 is connected to the left front map pocket upper cover assembly 13 via a connecting member. An angle is formed between the assembly connection portion 242 and the mounting base 241, and the angle between the two is set to 90°. And the assembly connection portion 242 is matched with connection bosses formed at different positions on the left front map pocket upper cover assembly 13. Therefore, the assembly connection portion 242 is arranged in a staggered manner to achieve the fixed connection with the left front map pocket upper cover assembly 13. Therefore, through the assembly connection portion 242 provided on the side of the mounting base 241 facing the map pocket chamber, and the assembly connection portion 242 is arranged at an angle of 90° with the mounting base 241, a spatial right-angle connection structure is formed between a single assembly connection portion 242 and the mounting base 241. And the assembly connection portion 242 adopts a staggered station design, and at least two groups of connection holes at different positions are provided thereon, respectively corresponding to the connection bosses provided at different positions on the left front map pocket upper cover assembly 13, so as to form a rigid constraint on the left front map pocket upper cover assembly in a three-dimensional space. And the spatial right-angle structure enables the assembly connection portion 242 to bear the Z-direction load and the Y-direction torque at the same time, and thus the connection stiffness can be effectively improved.

[0066] Moreover, when the assembly connection part 242 and the upper cover plate of the left front map pocket are fixedly connected by a connecting piece, a part of the connecting part extended from the upper trim panel assembly 1a is also arranged between the assembly connection part 242 and the upper cover plate assembly 13 of the left front map pocket. This part of the connecting part is arranged between the upper cover plate assembly of the map pocket and the assembly connection part 242. Furthermore, a connecting piece can penetrate through the above three structural parts, and the upper trim panel assembly 1a, the upper cover plate assembly 13 of the left front map pocket, and the assembly connection part 242 can be connected and fixed simultaneously, so as to realize the fixed connection between the structural parts of the upper trim panel assembly 1a and the lower trim panel assembly 2a, and further improve the overall structural strength of the formed car door.

[0067] During the assembly process, the connecting boss extended from the upper trim panel assembly 1a penetrates between the assembly connection part 242 and the upper cover plate assembly 13 of the left front map pocket, forming a "sandwich" - type laminated structure. A single M6 combination bolt penetrates through the connecting boss extended from the upper trim panel assembly 1a, the upper cover plate assembly 13 of the left front map pocket, and the assembly connection part 242 in sequence to realize the synchronous fastening of the three parts.

[0068] In one embodiment, the upper cover plate assembly 13 of the left front map pocket is arranged along the length direction of the car door, and a first structural fixing part 244 is formed at a section of the upper cover plate assembly 13 of the left front map pocket far from the second connection assembly 24. The first structural fixing part 244 is fixedly connected to a fixing part extended from the upper trim panel assembly 1a towards the lower cover plate assembly 17 of the left front map pocket via a connecting piece. And a fixing part of the upper trim panel assembly 1a continuously extends towards the lower cover plate assembly 17 of the left front map pocket so that the fixing part is fixedly connected to the lower cover plate assembly 17 of the left front map pocket. Among them, the first structural fixing part 244 is used to provide a fixing structural part for the upper cover plate assembly 13 of the left front map pocket at the distal end. Specifically, a fixing part extended from the upper trim panel assembly 1a can straddle the first structural fixing part 244 and extend to the position of the lower cover plate assembly 17 of the left front map pocket at the same time. Furthermore, when connecting, first connect the middle part of the first structural fixing part 244 and a fixing part extended from the upper trim panel assembly 1a, and then connect the lower cover plate assembly 17 of the left front map pocket and the lower part of a fixing part extended from the upper trim panel assembly 1a, so as to realize the fixed connection of the lower cover plate assembly 17 of the left front map pocket, the upper trim panel assembly 1a, and the first structural fixing part 244 at the distal end.

[0069] More specifically, a section of the upper cover assembly 13 of the left front map pocket near the second connection assembly 24 forms a second structure fixing part 245. The second structure fixing part 245 extends towards the lower cover assembly 17 of the left front map pocket and is fixedly connected to the lower cover assembly 17 of the left front map pocket. In addition, a plurality of alignment guiding structures 243 are provided on the second structure fixing part 245, and positioning holes are formed on the upper trim panel assembly 1a corresponding to the alignment guiding structures 243. The alignment guiding structures 243 are adapted to penetrate through the positioning holes to position the installation position of the upper cover assembly 13 of the left front map pocket.

[0070] Thus, through the connection between the first structure fixing part 244 and the second structure fixing part 245 to form a double - fulcrum rigid connection, the upper cover assembly 13 of the left front map pocket and the upper trim panel assembly 1a form a mechanical closed - loop, converting the single - point structure stress into a double - fulcrum bearing structure, so that the local stiffness can be increased by more than 40%, effectively suppressing the deformation amount during the opening and closing of the door and improving the structural strength. In addition, a composite connection method combining bolts and buckles is adopted, which not only ensures the initial assembly accuracy (the gap surface difference is controlled within ±0.3 mm), but also compensates for the difference in thermal expansion coefficients through the pre - tightening force of the buckles, improving the dimensional stability of the structural parts in different temperature environments, and further improving the assembly accuracy of the overall structure.

[0071] In addition, the modular design enables a single connection point failure not to affect the overall structure, and buckle connectors can be used to support rapid disassembly, shortening the after - sales maintenance man - hours by 50%, thereby reducing the full - life - cycle usage cost and improving the convenience of maintenance at the same time.

[0072] This embodiment further provides a vehicle, which adopts the above - mentioned front door trim panel assembly of the vehicle. By reasonably designing the structural assembly of the upper trim panel assembly 1a of the front door, the water cut structure 1 is connected to the front door structure skeleton 2 through the first connection assembly 3, and the first connection assembly 3 is arranged along the length direction of the water cut structure 1. This layout helps to evenly disperse the connection stress and ensure the stability and reliability of the overall structure assembly.

[0073] In addition, this structural design can perform installation positioning more efficiently and accurately during installation. The first connection assembly 3 is provided with a first connection part 301 and can be clamped with the corresponding part to achieve the preliminary positioning of the installation orientation of the water cut structure 1 and the first connection part 301, facilitating subsequent precise installation, improving the assembly efficiency, and reducing the installation deviation.

[0074] Meanwhile, since the first connection component 3 is adopted as the connecting member 12 between the water cut structure 1 and the front door structure framework 2, the overall structure is more firm and reliable after installation and connection. Since the first connection component 3 extends downward to form a plurality of second connection parts 302, which respectively correspond to the framework docking part 201 of the front door structure framework 2 and the water cut docking part 101 of the water cut structure 1, the connecting member 12 passes through the three parts at the same time to form a fixed connection. This multi-part and penetrating connection method greatly enhances the connection strength, ensures the firm connection between the water cut structure 1 and the front door structure framework 2, is not easy to loosen, and improves the overall structural strength and durability of the front door trim assembly of the vehicle.

[0075] Meanwhile, the above-mentioned lower front door trim assembly 2a of the vehicle includes a left front map pocket lower cover assembly 5, a left front map pocket upper cover assembly 1 and a left front map pocket baffle 7 that constitute a map pocket, and a second connection component 12 is provided on the left front map pocket baffle 7. Through the second connection component 12, local stress concentration can be dispersed, and the anti-dent deformation ability can be improved, which is especially suitable for scenarios of carrying items or bearing lateral forces. In addition, the installation base 121 of the second connection component 12 is designed with a slope structure. By changing the direction of force transmission (converting the vertical load into an inclined plane component force), the risk of shear stress concentration at the connection point is reduced, and at the same time, the contact area between the base and the baffle is increased to improve the connection stability. Moreover, the installation part extending from the left front map pocket baffle 7 and the side of the installation base 121 are fixed by a connecting member to form a lateral restraint structure. This design can effectively resist the torsional moment and prevent the baffle from loosening or displacing under long-term vibration or impact conditions, and significantly improve the fatigue strength of the connection node.

[0076] Thus, through the above design, the doors of the vehicle in this application can improve the overall structural strength from three dimensions: overall stiffness, local anti-deformation ability, and connection reliability.
