Description

Technical Field

[0001] This application belongs to the field of vehicle parts technology, and more specifically, relates to a door assembly and a vehicle. Background Technology

[0002] As a key load-bearing and sealing structure of the vehicle body, the door and window frames not only need to meet basic requirements such as assembly precision and sealing performance, but also need to withstand the complex dynamic loads during driving. However, existing vehicle door and window frames have multiple deficiencies in structural strength and vibration resistance, making them prone to abnormal noises on bumpy roads: on the one hand, the main body of the window frame often uses thin-walled profiles or simple splicing structures, lacking targeted reinforcement design, resulting in insufficient overall rigidity and vibration resistance; on the other hand, the cavity structure formed between the inner and outer panels of the window frame can easily become a channel for the transmission and amplification of vibration energy when the vehicle vibrates, exacerbating the overall vibration amplitude of the window frame.

[0003] To address the aforementioned abnormal noise issue, some improvement solutions have been proposed in the existing technology, such as increasing the wall thickness of the window frame profile to improve local stiffness, or adding a reinforcing plate between the inner and outer door panels to increase local strength. However, these solutions still have significant drawbacks and fail to fundamentally solve the problem: increasing the profile wall thickness will increase the vehicle's weight, and while adding a reinforcing plate can improve local stiffness, the reinforcing plate is attached to the inner or outer door panel, which can only increase the strength of the inner or outer panel individually and cannot suppress the vibration amplification effect caused by the cavity structure.

[0004] Therefore, existing solutions have failed to balance structural strength, lightweighting, and vibration resistance, especially neglecting the critical impact of cavity structures on abnormal noise. They cannot fundamentally solve the problem of abnormal noise in door and window frames under off-road dynamic scenarios, and there is an urgent need for a new door and window frame structural design to meet actual usage requirements. Utility Model Content

[0005] The purpose of this application is to provide a door assembly and vehicle, which aims to solve the problem that existing door and window frame structures are prone to abnormal noise after being subjected to vibration, and that existing solutions cannot simultaneously meet the requirements of structural strength and lightweighting.

[0006] In a first aspect, embodiments of this application provide a vehicle door assembly, including: The door inner panel includes an inner panel body and a window frame inner panel located on the upper part of the inner panel body; An outer door panel is disposed outside the inner door panel. The outer door panel includes an outer panel body and a window frame outer panel disposed on the upper part of the outer panel body. A reinforcing cavity is formed between the inner door panel and the outer door panel. A reinforcing mechanism is provided within the reinforcement cavity. The reinforcing mechanism includes a fixing part and a connecting part connected in the vertical direction. The connecting part is filled within the reinforcement cavity to achieve a flexible connection between the inner panel of the window frame and the outer panel of the window frame. The fixing part is used for a rigid connection with the inner panel of the window frame or the outer panel of the door.

[0007] The beneficial effects of the door assembly provided in this application are as follows: Compared with the prior art, by filling the reinforced cavity formed by the inner and outer panels of the door with a reinforcing mechanism, and with the connecting parts of the reinforcing mechanism respectively engaging with the inner and outer window frame panels, a flexible connection between the inner and outer window frame panels is achieved. This effectively fills the cavity between the inner and outer window frame panels, blocking the transmission and amplification path of vibration energy within the reinforced cavity, thus solving the problem of increased vibration caused by the cavity structure of existing door window frames. Simultaneously, the fixing part of the reinforcing mechanism is rigidly connected to the inner window frame panel or the outer door panel, improving the stability of the connection; the connecting part forms a stable load-bearing whole with the inner and outer window frame panels, effectively compensating for the insufficient rigidity of the door window frame caused by the opening of window mounting holes, suppressing the shaking and deformation of the vehicle when driving on bumpy roads, thereby eliminating friction and collision noises caused by vibration and improving the vehicle's NVH performance. This application abandons the existing technology of relying on increasing the wall thickness of the profile or adding reinforcing plates for strengthening. The strengthening mechanism, through the design of filling the reinforcement cavity, can significantly improve the structural strength and vibration resistance performance. At the same time, it can optimize its own structure according to the actual stress requirements and select high-strength lightweight materials, avoiding excessive increase in vehicle weight and balancing structural strength, vibration resistance performance and lightweight.

[0008] In conjunction with the first aspect, in one possible implementation, the outer door panel further includes a window frame reinforcing plate disposed within the reinforcing cavity, the window frame reinforcing plate being connected to the outer window frame panel to increase the local strength of the outer window frame panel.

[0009] In the above technical solution, the window frame reinforcing plate and the reinforcing mechanism within the reinforcement cavity form a synergistic reinforcement structure. The two work together within the reinforcement cavity, both filling the cavity and blocking vibration transmission through the reinforcing mechanism, and enhancing the local strength of the outer window frame panel through the window frame reinforcing plate, thus significantly improving the structural stability of the door window frame area. Furthermore, the position of the window frame reinforcing plate can be strategically placed according to the stress distribution of the outer window frame panel, only installed in areas with high strength requirements. This avoids redundant reinforcement of the overall window frame structure, preventing excessive increase in vehicle weight and balancing structural reliability with lightweight requirements.

[0010] In conjunction with the first aspect, in one possible implementation, the reinforcing mechanism includes: A filler body, filling the reinforced cavity and respectively joining the inner panel and outer panel of the window frame, the filler body forming the joint; and The mounting bracket is connected to the filler and is also fixed to the inner panel of the window frame and / or the reinforcing plate of the window frame, forming the fixing part.

[0011] In the above technical solution, the design of the filling and reinforcement cavity blocks the transmission and amplification path of vibration energy in the cavity from the root. At the same time, the mounting bracket forms a rigid linkage between the filling and the inner plate of the window frame and the reinforcing plate of the window frame, which not only strengthens the overall vibration resistance of the window frame, but also specifically improves the local stiffness and deformation resistance of key stress concentration areas, effectively suppressing abnormal noise caused by vibration.

[0012] In conjunction with the first aspect, in one possible implementation, the filler has a fixing groove, and the mounting bracket is inserted into the fixing groove and engaged with the filler.

[0013] In the above technical solution, the plug-in connection structure achieves the positioning and stable connection of the mounting bracket and the filler, ensuring the accuracy of their assembly positions and enhancing the stability and reliability of the connection, thus preventing separation due to vibration during vehicle operation. Furthermore, compared to traditional fixing methods such as bolt connections, plug-in assembly eliminates the need for additional fasteners, simplifying the assembly process, improving production efficiency, and avoiding the added weight associated with fasteners.

[0014] In conjunction with the first aspect, in one possible implementation, the mounting bracket has a fixed position and a guide position, the guide position being used for insertion and positioning with the inner panel of the window frame and / or the reinforcing plate of the window frame, and the fixed position being used for fixed connection with the inner panel of the window frame and / or the reinforcing plate of the window frame.

[0015] In the above technical solution, the guide is first inserted and positioned with the inner panel of the window frame and / or the reinforcing plate of the window frame to quickly calibrate the position of the mounting bracket. Then, the mounting bracket is fixed to the inner panel of the window frame and / or the reinforcing plate of the window frame through the fixing position. This solution improves assembly efficiency and avoids the reinforcing mechanism from failing to effectively perform its supporting and strengthening functions due to assembly deviations. At the same time, it ensures the reliability of the mounting bracket connection during vehicle operation, prevents relative displacement caused by vibration, and ensures the continuous and effective filling and support of the reinforcing cavity by the reinforcing mechanism. This stabilizes and blocks the transmission of vibration energy, strengthens the rigidity of the window frame structure, and suppresses abnormal noise at its source.

[0016] In conjunction with the first aspect, in one possible implementation, the reinforcing mechanism has a positioning area for insertion and positioning with the inner panel of the window frame.

[0017] In the above technical solution, the insertion and positioning of the positioning area and the inner panel of the window frame improves assembly efficiency and accuracy, ensuring the accurate installation position of the reinforcing mechanism within the reinforcement cavity. This avoids ineffective bonding between the infill and the inner and outer panels of the window frame due to assembly deviations. Simultaneously, the stable fit formed by the insertion and positioning enhances the connection reliability between the reinforcing mechanism and the inner panel of the window frame, preventing relative displacement due to vibration during vehicle operation. This ensures effective filling of the reinforcement cavity by the infill, continuously blocking vibration energy transmission, strengthening the structural rigidity of the window frame, and suppressing abnormal noise. Furthermore, this solution eliminates the need for additional fasteners or complex connection structures, effectively controlling vehicle weight while ensuring assembly stability and structural reinforcement, thus meeting lightweight design requirements.

[0018] In conjunction with the first aspect, in one possible implementation, the reinforcing mechanism has multiple independent weight-reducing grooves, and a reinforcing rib is formed between two adjacent weight-reducing grooves.

[0019] In the above technical solution, multiple independent weight-reduction grooves can remove redundant materials and reduce the weight of the strengthening mechanism itself while ensuring the structural strength of the strengthening mechanism. This meets the overall lightweight requirements of the vehicle body and avoids the problem of increased vehicle weight caused by structural reinforcement. The reinforcing ribs formed between adjacent weight-reduction grooves can ensure the structural rigidity and deformation resistance of the strengthening mechanism. With the distributed arrangement of the weight-reduction grooves, the strengthening mechanism can maintain excellent vibration resistance while achieving lightweighting. This ensures effective filling and support of the reinforcement cavity between the inner and outer panels of the window frame, blocks the transmission of vibration energy, and suppresses the vibration and abnormal noise of the door and window frames.

[0020] In conjunction with the first aspect, in one possible implementation, the inner panel of the window frame has a receiving groove adapted to the reinforcing mechanism, the reinforcing mechanism being disposed within the receiving groove.

[0021] In the above technical solution, the receiving groove provides installation space for the reinforcing mechanism, enabling its installation and positioning. This ensures accurate assembly of the reinforcing mechanism with the inner window frame panel, preventing assembly deviations that could prevent the reinforcing mechanism from fully engaging with the inner and outer window frame panels, thus guaranteeing its effective filling and support of the reinforcement cavity. Simultaneously, the reinforcing mechanism's embedding within the receiving groove enhances the tightness of the connection and the overall structural integrity, improving the synergistic vibration resistance of the reinforcing mechanism and the inner window frame panel. This prevents relative displacement or loosening due to vibration during vehicle operation, thereby continuously blocking vibration energy transmission, strengthening the overall rigidity of the window frame, and effectively suppressing abnormal noise.

[0022] In conjunction with the first aspect, in one possible implementation, the reinforcing mechanism has a first fastening hole, the inner panel of the window frame has a second fastening hole corresponding to the first fastening hole, and the door assembly further includes fasteners inserted into the first fastening hole and the second fastening hole.

[0023] In the above technical solution, the fasteners achieve a stable connection between the reinforcing mechanism and the inner panel of the window frame by passing through the first and second fastening holes. This prevents relative displacement or loosening of the two due to vibration during vehicle operation, ensuring that the reinforcing mechanism always maintains effective filling and support of the reinforcement cavity, continuously blocking the transmission of vibration energy, strengthening the structural rigidity of the window frame, and suppressing abnormal noise at its source. This embodiment features precise positioning and reliable connection, ensuring the assembly accuracy of the reinforcing mechanism and the inner panel of the window frame, ensuring a tight fit between the filler and the inner and outer panels of the window frame, and further improving the vibration resistance and noise reduction effect.

[0024] Secondly, embodiments of this application also provide a vehicle including the aforementioned door assembly.

[0025] The beneficial effects of the vehicle provided in this application are as follows: Compared with the prior art, the aforementioned door assembly, by filling the reinforced cavity formed by the inner and outer door panels with a reinforcing mechanism, and with the connecting parts of the reinforcing mechanism respectively engaging with the inner and outer window frame panels, achieves a flexible connection between the inner and outer window frame panels. This effectively fills the cavity between the inner and outer window frame panels, blocking the transmission and amplification path of vibration energy within the reinforced cavity, thus solving the problem of increased vibration caused by the cavity structure of existing door window frames. Simultaneously, the fixing part of the reinforcing mechanism is rigidly connected to the inner window frame panel or the outer door panel, improving the stability of the connection; the connecting part forms a stable load-bearing whole with the inner and outer window frame panels, effectively compensating for the insufficient rigidity of the door window frame caused by the opening of window mounting holes, suppressing the shaking and deformation of the vehicle when driving on bumpy roads, thereby eliminating friction and collision noises caused by vibration and improving the vehicle's NVH performance. This application abandons the existing technology of relying on increasing the wall thickness of the profile or adding reinforcing plates for strengthening. The strengthening mechanism, through the design of filling the reinforcement cavity, can significantly improve the structural strength and vibration resistance performance. At the same time, it can optimize its own structure according to the actual stress requirements and select high-strength lightweight materials, avoiding excessive increase in vehicle weight and balancing structural strength, vibration resistance performance and lightweight.

[0034] Please refer to the following: Figures 1 to 6 The following describes the door assembly and vehicle provided in this application. The door assembly includes an inner door panel 1, an outer door panel 2, and a reinforcing mechanism 3. The inner door panel 1 includes an inner panel body 101 and a window frame inner panel 102 disposed on the upper part of the inner panel body 101. The outer door panel 2 is disposed on the outer side of the inner door panel 1 and includes an outer panel body 201 and a window frame outer panel 202 disposed on the upper part of the outer panel body 201. A reinforcing cavity is formed between the inner door panel 1 and the outer door panel 2. The reinforcing mechanism 3 is disposed in the reinforcing cavity and includes a fixing part and a connecting part connected in the vertical direction. The connecting part is filled in the reinforcing cavity to achieve a flexible connection between the window frame inner panel 102 and the window frame outer panel 202. The fixing part is used for a rigid connection with the window frame inner panel 102 or the outer door panel.

[0035] Compared with the prior art, the door assembly provided in this application fills the reinforced cavity formed by the inner door panel 1 and the outer door panel 2 with a reinforcing mechanism 3. The connecting part of the reinforcing mechanism 3 is respectively engaged with the inner window frame panel 102 and the outer window frame panel 202, achieving a flexible connection between the inner window frame panel 102 and the outer window frame panel 202. This effectively fills the cavity between the inner window frame panel 102 and the outer window frame panel 202, blocking the transmission and amplification path of vibration energy in the reinforced cavity, and solving the problem of aggravated vibration caused by the cavity structure of existing door window frames. At the same time, the fixing part of the reinforcing mechanism 3 is rigidly connected to the inner window frame panel 102 or the outer door panel 2, improving the stability of the connection; the connecting part forms a stable force-bearing whole with the inner window frame panel 102 and the outer window frame panel 202, effectively compensating for the insufficient rigidity of the door window frame caused by the opening of the window mounting holes, suppressing the shaking and deformation of the vehicle when driving on bumpy roads, thereby eliminating friction and collision noise caused by vibration and improving the NVH performance of the vehicle. This application abandons the existing technology of strengthening by increasing the thickness of the profile wall or adding reinforcing plates. The strengthening mechanism 3, through the design of filling the reinforcement cavity, can significantly improve the structural strength and vibration resistance, while optimizing its own structure according to the actual stress requirements and selecting high-strength lightweight materials, thus avoiding excessive increase in the weight of the vehicle body and balancing structural strength, vibration resistance and lightweight.

[0036] It should be noted that "joining" refers to connecting or attaching two or more components in a specific way to form a stable and coordinated relationship, making each component a unified force-bearing body, and at the same time realizing functions such as force transmission, structural reinforcement or sealing.

[0037] Please see Figure 3 In some embodiments, the outer door panel 2 includes a window frame reinforcing plate 4 disposed in the reinforcement cavity. The window frame reinforcing plate 4 is connected to the outer window frame panel 202 and is used to increase the local strength of the outer window frame panel 202.

[0038] The window frame reinforcing plate 4 forms a stable connection directly with the outer window frame panel 202, compensating for the localized weakness in the outer window frame panel 202 caused by the window mounting holes and thin-walled design. It also disperses external forces acting on the outer window frame panel 202 during driving, preventing deformation or swaying caused by concentrated localized forces. Simultaneously, the window frame reinforcing plate 4 and the reinforcing mechanism 3 within the reinforcement cavity form a synergistic reinforcement structure. Working together within the reinforcement cavity, the reinforcing mechanism 3 fills the cavity and blocks vibration transmission, while the window frame reinforcing plate 4 enhances the localized strength of the outer window frame panel 202, significantly improving the structural stability of the door window frame area. Furthermore, the position of the window frame reinforcing plate 4 can be strategically placed according to the stress distribution of the outer window frame panel 202, only installed in areas with high strength requirements. This avoids redundant reinforcement of the overall window frame structure, preventing excessive weight increase and balancing structural reliability with lightweight requirements.

[0039] Optionally, the window frame reinforcing plate 4 is located at the corner of the outer window frame panel 202, preferably at the lower corner of the outer window frame panel 202. This area is a stress concentration area of ​​the car door window frame, and it is subjected to greater force when the car door is opened or closed, which can easily cause deformation and abnormal noise. Therefore, adding the window frame reinforcing plate 4 in this area can effectively improve the local strength and reduce the probability of deformation and abnormal noise.

[0040] Please see Figures 5 to 6 In some embodiments, the reinforcing mechanism 3 includes a filler 301 and a mounting bracket 302. The filler 301 fills the reinforcing cavity and is respectively joined to the inner panel 102 and the outer panel 202 of the window frame, forming a joint. The mounting bracket 302 is connected to the filler 301 and is also fixed to the inner panel 102 and / or the reinforcing plate 4 of the window frame, forming a fixing part.

[0041] During assembly, the mounting bracket 302 is first fixed to the inner panel 102 of the window frame and / or the reinforcing plate 4 of the window frame to secure the filler 301. After the inner panel 1 and the outer panel 2 of the door are connected, the area of ​​the filler 301 is heated from the outside, causing the filler 301 to expand due to heat, thereby filling the reinforced cavity and joining the inner panel 102 and the outer panel 202 of the window frame. This assembly process not only achieves the fixed-point positioning of the mounting bracket 302, but also provides a reliable assembly benchmark for the filler 301, ensuring the accurate installation position of the filler 301 within the reinforced cavity.

[0042] The filling material 301 fills the reinforced cavity, which fundamentally blocks the transmission and amplification path of vibration energy in the cavity. At the same time, the mounting bracket 302 forms a rigid linkage between the filling material 301 and the inner plate 102 of the window frame and the reinforcing plate 4 of the window frame. This not only strengthens the overall vibration resistance of the window frame, but also specifically improves the local stiffness and deformation resistance of key stress concentration areas, effectively suppressing abnormal noises caused by vibration.

[0043] Optionally, the infill 301 also has a connecting part located between the window frame reinforcing plate 4 and the window frame inner plate 102. The connecting part, the window frame reinforcing plate 4, and the window frame inner plate 102 are rigidly connected, which strengthens the structural integrity of the stress concentration area of ​​the window frame structure, improves the local vibration and deformation resistance, and effectively suppresses the generation of abnormal noise.

[0044] Optionally, the mounting bracket 302 can be connected to the inner panel 102 of the window frame or the reinforcing plate 4 of the window frame by means of screwing, snap-fitting, welding, or riveting.

[0045] Specifically, the filler 301 can be an adhesive, such as structural adhesive or expanding foam. After electrophoresis and baking, the filler 301 expands and hardens. The expanded filler 301 stably supports the inner window frame panel 102 and the outer window frame panel 202, strengthening the rigidity of the window frame structure and effectively reducing abnormal noises generated by the window frame structure during bumps. The mounting bracket 302 is a rigid component, such as a metal component or a plastic component, preferably a metal component.

[0046] Please see Figure 3 and Figure 5 In some embodiments, the filler 301 has a fixing groove, and the mounting bracket 302 is inserted into the fixing groove and engaged with the filler 301.

[0047] The plug-in connection structure enables the mounting bracket 302 and the filler 301 to be positioned and securely connected, ensuring the accuracy of their assembly positions and enhancing the stability and reliability of the connection, preventing separation due to vibration during vehicle operation. Furthermore, compared to traditional fixing methods such as bolt connections, the plug-in assembly eliminates the need for additional fasteners, simplifying the assembly process, improving production efficiency, and avoiding the added weight associated with fasteners.

[0048] It should be noted that "the mounting bracket 302 is connected to the filler 301" means that the mounting bracket 302 and the filler 301 are connected by means of screwing, snapping, riveting, welding, or bonding. The mounting bracket 302 and the filler 301 can be completely fitted and fixed, or they can be partially in contact for fixation. In this embodiment, "the mounting bracket 302 is engaged with the filler 301" means that the mounting bracket 302 and the filler 301 are completely fitted and fixed.

[0049] Optionally, the mounting bracket 302 is a rigid component, such as a metal component or a plastic component, and the filler 301 is one of structural adhesive or foam adhesive. The filler 301 and the mounting bracket 302 are formed into an integral component by plastic coating process.

[0050] Optionally, the fixing groove is coated with adhesive, the mounting bracket 302 is inserted into the fixing groove, and the fixing connection with the filler 301 is achieved by adhesive.

[0051] Please see Figures 5 to 6 In some embodiments, the mounting bracket 302 has a fixed position and a guide position 3021. The guide position 3021 is used for insertion and positioning with the inner panel 102 of the window frame and / or the reinforcing plate 4 of the window frame, and the fixed position is used for fixed connection with the inner panel 102 of the window frame and / or the reinforcing plate 4 of the window frame.

[0052] First, the guide 3021 is inserted and positioned with the inner panel 102 of the window frame and / or the reinforcing plate 4 of the window frame to quickly calibrate the position of the mounting bracket 302. Then, the mounting bracket 302 is fixedly connected to the inner panel 102 of the window frame and / or the reinforcing plate 4 through the fixing position. This solution improves assembly efficiency and avoids the reinforcing mechanism 3 from failing to effectively perform its supporting and strengthening functions due to assembly deviations. At the same time, it ensures the reliability of the mounting bracket 302 connection during vehicle operation, prevents relative displacement caused by vibration, and ensures the continuous and effective filling and support of the reinforcing cavity by the reinforcing mechanism 3. This stabilizes and blocks the transmission of vibration energy, strengthens the rigidity of the window frame structure, and suppresses abnormal noise at its source.

[0053] Please see Figures 5 to 6 In some embodiments, the reinforcing mechanism 3 has a positioning area 303 for insertion and positioning with the inner panel 102 of the window frame.

[0054] The insertion and positioning of the positioning area 303 with the inner window frame panel 102 improves assembly efficiency and accuracy, ensuring the accurate installation position of the reinforcing mechanism 3 within the reinforced cavity. This prevents the filler 301 from failing to effectively connect with the inner window frame panel 102 and the outer window frame panel 202 due to assembly deviations. Simultaneously, the stable fit formed by the insertion and positioning enhances the connection reliability between the reinforcing mechanism 3 and the inner window frame panel 102, preventing relative displacement due to vibration during vehicle operation. This ensures the effective filling effect of the filler 301 into the reinforced cavity, thereby continuously blocking vibration energy transmission, strengthening the window frame structure rigidity, and suppressing abnormal noise. Furthermore, this solution eliminates the need for additional fasteners or complex connection structures, effectively controlling vehicle weight while ensuring assembly stability and structural reinforcement, thus meeting lightweight design requirements.

[0055] Optionally, the reinforcing mechanism 3 has a positioning hole, which forms a positioning area 303.

[0056] Please see Figure 5 In some embodiments, the reinforcing mechanism 3 has multiple independent weight-reducing grooves 3011, and a reinforcing rib is formed between two adjacent weight-reducing grooves 3011.

[0057] Multiple independent weight-reduction grooves 3011 can remove redundant materials and reduce the weight of the reinforcing mechanism 3 itself while ensuring the structural strength of the reinforcing mechanism 3, thereby meeting the overall lightweight requirements of the vehicle body and avoiding the problem of increased vehicle body weight due to structural reinforcement. The reinforcing ribs formed between adjacent weight-reduction grooves 3011 can ensure the structural rigidity and deformation resistance of the reinforcing mechanism 3. With the distributed arrangement of the weight-reduction grooves 3011, the reinforcing mechanism 3 can maintain excellent vibration resistance while being lightweight, ensuring effective filling and support of the reinforcement cavity between the inner panel 102 and the outer panel 202 of the window frame, blocking the transmission of vibration energy, and suppressing the vibration and abnormal noise of the door and window frames.

[0058] Please see Figure 2 In some embodiments, the inner panel 102 of the window frame has a receiving groove adapted to the reinforcing mechanism 3, which is disposed in the receiving groove.

[0059] The receiving groove provides installation space for the reinforcing mechanism 3, enabling its installation and positioning. This ensures accurate assembly of the reinforcing mechanism 3 with the inner window frame panel 102, preventing assembly deviations that could prevent the reinforcing mechanism 3 from fully engaging with the inner window frame panel 102 and the outer window frame panel 202. This guarantees its effective filling and support of the reinforcement cavity. Simultaneously, the embedding of the reinforcing mechanism 3 within the receiving groove enhances the tightness of the connection and the overall structural integrity, improving the synergistic vibration resistance of the reinforcing mechanism 3 and the inner window frame panel 102. This prevents relative displacement or loosening due to vibration during vehicle operation, continuously blocking vibration energy transmission, strengthening the overall rigidity of the window frame, and effectively suppressing abnormal noise.

[0060] Please see Figures 5 to 6 In some embodiments, the reinforcing mechanism 3 has a first fastening hole 304, the inner panel 102 of the window frame has a second fastening hole corresponding to the first fastening hole 304, and the door assembly also includes fasteners inserted into the first fastening hole 304 and the second fastening hole.

[0061] The fasteners, passing through the first and second fastening holes, ensure a stable connection between the reinforcing mechanism 3 and the inner window frame panel 102. This prevents relative displacement or loosening due to vibration during vehicle operation, ensuring that the reinforcing mechanism 3 effectively fills and supports the reinforced cavity, continuously blocking vibration energy transmission, strengthening the rigidity of the window frame structure, and suppressing abnormal noise at its source. This embodiment features precise positioning and reliable connection, guaranteeing the assembly accuracy of the reinforcing mechanism 3 and the inner window frame panel 102, ensuring a tight fit between the filler 301 and the inner window frame panel 102 and the outer window frame panel 202, further enhancing vibration resistance and noise reduction.

[0062] Optionally, the fasteners can be snap-fit ​​or screw-fit.

[0063] Optionally, the reinforcing mechanism 3 also has a reinforcing rib 305, which is located on the outer periphery of the first fastening hole 304 and is used to improve the strength and deformation resistance of the outer periphery of the first fastening hole 304.

[0064] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the aforementioned door assembly.

[0065] The vehicle provided by this utility model adopts the aforementioned door assembly. By filling the reinforced cavity formed by the inner door panel 1 and the outer door panel 2 with a reinforcing mechanism 3, and with the connecting parts of the reinforcing mechanism 3 respectively engaging with the inner window frame panel 102 and the outer window frame panel 202, a flexible connection is achieved between the inner window frame panel 102 and the outer window frame panel 202. This effectively fills the cavity between the inner window frame panel 102 and the outer window frame panel 202, blocking the transmission and amplification path of vibration energy within the reinforced cavity, thus solving the problem of increased vibration caused by the cavity structure of existing door window frames. Simultaneously, the fixing part of the reinforcing mechanism 3 is rigidly connected to the inner window frame panel 102 or the outer door panel 2, improving the stability of the connection. The connecting part forms a stable load-bearing whole with the inner window frame panel 102 and the outer window frame panel 202, effectively compensating for the insufficient rigidity of the door window frame caused by the opening of window mounting holes, suppressing the shaking and deformation of the vehicle when driving on bumpy roads, thereby eliminating friction and collision noises caused by vibration and improving the vehicle's NVH performance. This application abandons the existing technology of strengthening by increasing the thickness of the profile wall or adding reinforcing plates. The strengthening mechanism 3, through the design of filling the reinforcement cavity, can significantly improve the structural strength and vibration resistance, while optimizing its own structure according to the actual stress requirements and selecting high-strength lightweight materials, thus avoiding excessive increase in the weight of the vehicle body and balancing structural strength, vibration resistance and lightweight.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
