Description

Technical Field

[0001] This invention relates to the field of automotive body drainage technology, and more particularly to a door panel drainage structure. Background Technology

[0002] In the current technological system of automotive door interior trim, the inner triangular block of the front door panel and the door panel body are two independent modular components. Their assembly typically involves simple splicing or snap-fit ​​joints. The industry has not designed dedicated water drainage paths and structures to address the need for drainage of residual water during the routine after-sales installation of window tinting. Existing waterproofing designs for automotive door interior trim only focus on blocking rainwater from the outside of the door during rainy days, using drainage holes in the door sheet metal to drain external water. However, they neglect the hidden water ingress path of residual tinting film seeping into the inside of the trim through the gap between the glass and the inner triangular block. In most car models, the joint between the inner triangular block and the main frame of the door panel is only a basic bonding treatment, without any water guiding or blocking structure. Some water or film liquid generated during the film application process will flow down the glass surface and seep into the inside of the door panel through the side gaps between the glass and the inner triangular block. The inside of the door panel contains a dense array of electronic circuits and connectors such as window lift harnesses, door lock control harnesses, and speaker wiring, making it a core area prone to water accumulation and corrosion. Furthermore, the existing door panel main frame does not have a planned continuous water guiding channel, so the seeping water has no fixed drainage path and is prone to accumulating inside the panel. Summary of the Invention

[0021] This invention relates to a waterproof drainage structure design for automotive front door interior trim, specifically an integrated drainage channel structure incorporating a triangular block within the door panel and the door panel's main frame. This structure is primarily used in the front door areas of various passenger and commercial vehicles, enabling efficient collection, directional drainage, and rapid discharge of residual water after window tinting. It fundamentally prevents water from seeping into core components such as electronic circuits and wiring harness connectors inside the door panel, preventing problems such as short circuits, metal corrosion, and malfunctions of onboard electronic functions. Simultaneously, it improves the waterproof durability and reliability of the automotive door interior trim structure, aligning with automotive manufacturing and assembly standards.

[0022] This invention aims to overcome the technical shortcomings of existing automotive door panel structures, such as the lack of a dedicated water drainage path for residual film, easy water leakage leading to electronic malfunctions, and low drainage efficiency. It provides a water drainage channel structure for the inner triangular block and the door panel body. By integrating continuous water drainage channels that interlock on the inner triangular block and the door panel frame, combined with a scientifically designed water flow path control structure, it achieves source collection, directional drainage, and rapid discharge of residual water from the window film. This fundamentally prevents water from seeping into the electronic circuits, wiring harness connectors, and other components inside the door panel, solving problems such as short circuits, corrosion, and electronic malfunctions. Simultaneously, this structure considers ease of assembly and maintenance, adapts to existing automotive door assembly standards, achieves a balance between water drainage function and structural practicality, and improves the waterproof durability and overall performance of automotive door interiors.

[0023] In the existing technology system of automotive door interiors, the inner triangular block 1 of the front door panel, the door panel body 2, and the decorative panel 4 on the door panel are all independent modular components. When assembling the inner triangular block 1, the door panel body 2, and the decorative panel 4 on the door panel, they mostly adopt simple splicing, snap-fit, and plug-in joint structures. In most models, the splicing of the inner triangular block 1 and the decorative panel 4 on the door panel is only basically fitted, without any water guiding or blocking structures. Moreover, after the decorative panel 4 on the door panel and the inner triangular block 1 are assembled, there will be a certain gap between them.

[0024] After purchasing a new car, customers typically apply protective film to the windows. Window tinting offers several benefits: 1. It blocks some heat, saving fuel and electricity. The film blocks a significant amount of sunlight, reducing the interior temperature under direct sunlight. This slows down the temperature rise inside the car, allowing for quicker cooling from parking and less exposure to high temperatures. It also reduces the load on the air conditioning, lowering fuel and electricity consumption, and making long drives more comfortable. 2. It blocks ultraviolet rays, protecting skin and interior materials. High-quality film blocks over 99% of UV rays, protecting passengers from sunburn and preventing tanning. It also prevents fading, cracking, and aging of the leather and plastic on the dashboard, seats, and door panels. Third, privacy protection: When using dark-colored anti-peeping film, it is not clear from outside the car what items or people are inside. After parking, valuables are less likely to be targeted by passersby, increasing a sense of security. Fourth, explosion-proof safety: When the car window glass breaks, the adhesive layer of the film will firmly stick the broken glass, preventing it from flying and injuring people. In the event of a car accident, stone hitting the glass, or falling objects from a height, it can also prevent broken glass from cutting the face, hands, and feet to a certain extent. Fifth, anti-glare: Improve driving safety by blocking strong light, midday sun, and glare from oncoming headlights at night to a certain extent, reducing eye strain and visual fatigue.

[0025] When applying window film, workers spray water onto the glass before applying the film. Although absorbent towels and paper towels are used to dry excess water afterward, due to different workers' techniques, some water may still seep into the door panel through the gap between the decorative panel 4 and the inner triangular block 1. On some models, the joint between the inner triangular block 1 and the decorative panel 4 is only a basic fit, without any water-guiding or blocking structures. A large amount of water or film liquid generated during the application process will flow down the glass surface and seep into the door panel through the side gaps between the decorative panel and the inner triangular block. Because the door panel contains a dense array of electronic circuits and connectors, including window lift wiring harnesses, door lock control wiring harnesses, and speaker wiring, water can seep in through the gap between the decorative panel 4 and the inner triangular block 1 on the door panel. Since the interior of the door is relatively enclosed and poorly ventilated, if the water cannot evaporate for a long time, it will gradually seep into the wiring harness connectors along the gaps, causing short circuits and oxidation of the metal pins of the connectors. This can directly lead to the failure of vehicle electronic functions such as window lift, door lock, and rearview mirror adjustment. In severe cases, it can also cause the wiring harness to age and break, creating potential electrical safety hazards for the vehicle. The interior of the door panel contains a dense array of electronic circuits and connectors, including window lift harnesses, door lock control harnesses, and speaker wiring. This makes it a prime area for water accumulation and corrosion. Furthermore, the seeping water has no fixed drainage path and tends to accumulate inside the door panel. The water can also overflow at the junction of the triangular block inside the door panel and the main frame of the door panel, failing to be directed to the door sheet metal drainage holes. This water will accumulate in the cavity between the door panel and the door sheet metal for a long time, not only soaking the plastic frame and causing parts to age and deform, but also breeding mold and producing odors, affecting the interior environment of the vehicle.

[0026] To improve the overall sealing of the door panels, some models use adhesive bonding at the joint between the inner triangular block and the decorative panel on the door panel. While this can reduce water seepage to some extent, the adhesive sealing layer is easily damaged during disassembly for vehicle repairs. After reassembly, it is difficult to restore the original waterproof effect, leading to a worsening of the water seepage problem. At the same time, the adhesive bonding method also increases the difficulty of replacing parts, increasing the time and cost of after-sales repairs.

[0027] There is a lack of industry-specific requirements for residual water drainage in the routine after-sales installation of car window tinting. Specifically, existing interior triangular blocks and door panel frames lack well-designed water drainage channels to remove water accumulated during tinting. Current waterproofing designs for car door interiors typically focus only on blocking rainwater from the outside of the door during rainy days, draining external water through drainage holes in the door sheet metal. However, they neglect the hidden water ingress path of residual tinting water seeping into the inside of the door panel through the gap between the trim panel and the interior triangular block. Existing door panel structures with simple water drainage features mostly have single, straight drainage channels without slope design or backflow prevention measures. This results in low water drainage efficiency, making water stagnation or backflow prone to occur, failing to meet the actual water drainage needs of use.

[0028] Therefore, in view of the many shortcomings of existing technologies, the industry urgently needs a door panel water channel structure that can efficiently guide and directionally discharge residual water from window tinting film. By optimizing the structure of the triangular block inside the door panel and the door panel body, an integrated water guiding and drainage system is designed to form a complete water flow path from the water source to the drainage end, completely solving the problem of water accumulation inside the door panel, ensuring the normal functioning of in-vehicle electrical components, while also taking into account the ease of assembly and maintenance compatibility of the structure.

[0029] In this embodiment, the present invention provides a door panel drainage structure, including an inner triangular block 1 and a door panel body 2. An upper water guide box 101 is provided on the rear side of the inner triangular block 1, and an upper water guide groove 102 is provided in the upper water guide box 101. A lower water collection box 201 is provided on the door panel body 2 below the upper water guide groove 102, and a lower water collection box 201 is provided in the lower water collection box 201, with a lower water guide groove 202. Water flows out from the lower water guide groove 202 and then flows downwards along the inner sidewall of the door panel body 2 before being discharged. In this embodiment, a set of water guide boxes 101 with upper water guide grooves 102 is designed on the rear side of the inner triangular block 1 to catch the membrane-covered water flowing down from the first drainage gap 10 between the inner triangular block 1 and the decorative panel 4 on the door panel.

[0030] A decorative panel 4 is fixedly connected to the door panel body 2. The front side of the decorative panel 4 has a recessed groove 401 adapted to the inner triangular block 1. A first drainage gap 10 is provided between the rear edge of the recessed groove 401 and the rear sidewall of the inner triangular block 1. The first drainage gap 10 is located above the upper water guide groove 102. Since the inner triangular block 1, the door panel body 2, and the decorative panel 4 are often assembled using simple splicing, snap-fit, or plug-in joints, and in most models, the splicing point between the inner triangular block 1 and the decorative panel 4 is only a basic fit, a certain size first drainage gap 10 will remain between the decorative panel 4 and the inner triangular block 1 after assembly. Water accumulated on the film will flow from this gap into the upper water guide box 101 located on the rear side of the inner triangular block 1. If the first drainage gap 10 is sealed with adhesive, the water seepage problem can be reduced. However, the adhesive sealing layer will be damaged during vehicle maintenance, and it will be difficult to restore the original waterproof effect after reassembly. At the same time, the adhesive assembly method also increases the difficulty of replacing parts, increasing the time and cost of maintenance.

[0031] A second drainage gap 20 is provided between the inner edge of the upper water guide channel 102 and the outer wall of the door panel body 2. The second drainage gap 20 is located above the lower water guide channel 202. In order to smoothly guide the water in the upper water guide box 101 into the lower water collection box 201, a second drainage gap 20 of a certain size needs to be provided between the inner edge of the upper water guide channel 102 and the outer wall of the door panel body 2. The accumulated water flows down through the upper water guide channel 102 of the upper water guide box 101 and falls into the lower water guide channel 202 of the lower water collection box 201 through the second drainage gap 20.

[0032] To limit the flow of water, prevent it from flowing to other areas of the vehicle door, and prevent water from flowing back into other areas when the vehicle is going uphill, a rear water baffle 103 is provided on the rear side of the upper water guide channel 102, and a lower water baffle 104 connected to the rear water baffle 103 is provided at the bottom of the upper water guide channel 102. The opening of the lower water collection box 201 faces upward and is located below the outlet of the lower water baffle 104 so as to catch the water flowing down from the outlet of the upper water guide channel 102.

[0033] To ensure that accumulated water flows smoothly out of the upper water guide channel 102 through the guide structure, the upper water guide channel 102 is provided with a first water guide slope 1021 and a second water guide slope 1022. The first water guide slope 1021 and the second water guide slope 1022 are connected. The first water guide slope 1021 is inclined downwards towards the inside of the vehicle, and the second water guide slope 1022 is inclined downwards towards the rear of the vehicle. That is, both the first water guide slope 1021 and the second water guide slope 1022 extend downwards at an angle. The first water guide slope 1021 is used to guide the accumulated water flowing down from the first drainage gap 10 to the second water guide slope 1022, and the second water guide slope 1022 is used to guide the accumulated water to the lower water collection box 201. The slope of the second water guide slope 1022 can be set to 3-5° to ensure that the water flows automatically to the drain outlet under the action of gravity.

[0034] To allow water to drain from the lower water collection box 201, a third water guiding slope 2021 is provided in the lower water guide channel 202. This third water guiding slope 2021 is inclined downwards towards the inside of the vehicle. The slope of the third water guiding slope 2021 can be set to 3-5° to ensure that water flows automatically to the drain outlet under gravity. A through groove can be opened on the upper front side of the door panel body 2 to form a lower water guide channel 202 with the third water guiding slope 2021, allowing water to drain along the third water guiding slope 2021 and the inner wall of the door panel body 2.

[0035] To facilitate the assembly and fixing of the inner triangular block 1 and the door panel body 2, a first slot 105 is provided at the lower part of the inner triangular block 1, and a first buckle 203 is fixedly provided at the upper front side of the door panel body 2. The first buckle 203 is engaged with the first slot 105 to complete the fixing.

[0036] The inner side of the door panel body 2 is fixedly connected to the door panel trim panel 3. A third drainage gap 30 communicating with the lower water guide channel 202 is provided between the inner wall of the door panel body 2 and the outer wall of the door panel trim panel 3. This gap is used to drain the water flowing out of the lower water guide channel 202. The door panel trim panel 3 serves to conceal and beautify the interior, covering the metal sheet metal, wiring harness, and mechanical structure of the door, thereby enhancing the visual quality and luxury of the interior. The side of the door panel body 2 and the door panel trim panel 3 facing outward can be filled with sound insulation cotton or foam material to effectively shield external noise and reduce vibration, improving the quietness of the ride.

[0037] To facilitate the assembly and fixing of the trim panel 3 in the door panel and the decorative panel 4 on the door panel, the upper part of the trim panel 3 in the door panel is provided with several sets of first connecting holes 301 at intervals, and the side of the decorative panel 4 on the door panel facing outwards is provided with several sets of first connecting protrusions 402 at intervals, the first connecting protrusions 402 passing through the first connecting holes 301. In this embodiment, several sets of protrusions can be provided at the upper end of the trim panel 3 in the door panel, and the first connecting holes 301 are opened on the protrusions; the first connecting protrusions 402 are provided on the side of the decorative panel 4 on the door panel facing outwards. During assembly, the first connecting protrusions 402 are inserted into the first connecting holes 301, and then the trim panel 3 in the door panel and the decorative panel 4 on the door panel are fixed into a whole by ultrasonic welding.

[0038] To facilitate the assembly and fixing of the door panel body 2 and the door panel trim 3, the lower part of the door panel trim 3 is provided with several sets of second connecting protrusions 302 at intervals, and the upper part of the door panel body 2 is provided with second connecting holes 204 at intervals. The second connecting protrusions 302 pass through the second connecting holes 204. In this embodiment, the second connecting protrusions 302 can be provided on the lower part of the door panel trim 3 facing outwards, and the second connecting holes 204 can be opened on the upper part of the door panel body 2 near the edge. During assembly, the second connecting protrusions 302 are inserted into the second connecting holes 204, and then the door panel body 2 and the door panel trim 3 are fixed into a whole by ultrasonic welding.

[0039] To facilitate the support, positioning, and assembly of the decorative panel 4 on the door guard plate, a door guard plate mounting bracket 5 is fixedly connected to the bottom of the decorative panel 4. The bottom of the mounting bracket 5 has several sets of third connecting holes 501 spaced apart. During assembly, the third connecting holes 501 are aligned with the first connecting holes 301. The first connecting protrusions 402 pass through the third connecting holes 501 and the first connecting holes 301 in sequence before being ultrasonically welded. The bottom of the mounting bracket 5 also has several sets of second slots 502 spaced apart, and the bottom of the decorative panel 4 has several sets of second buckles 403 spaced apart. The second buckles 403 are inserted into the second slots 502.

[0040] like Figure 4As shown, the drainage path of the present invention is as follows: accumulated water flows sequentially through the first drainage gap 10, the upper water guide channel 102, the first water guide slope 1021 of the upper water guide channel 102, the second water guide slope 1022 of the upper water guide channel 102, the second drainage gap 20, the lower water guide channel 202, the third water guide slope 2021 of the lower water guide channel 202, and the third drainage gap 30 to the lower part of the car door. Then, excess water can be wiped away. A complete water flow path is formed from the water inlet to the drainage outlet, which completely solves the problem of water accumulation inside the door panel, ensures the normal functioning of electrical components inside the car door, and also takes into account the ease of assembly and maintenance compatibility of the structure.

[0041] Compared with existing technologies, this invention has the following advantages: efficient water drainage; the integrated continuous water channel structure can collect and discharge residual water from the film outside the vehicle, completely eliminating the risk of water accumulation inside the door panel; convenient assembly and maintenance; the modular snap-fit ​​design and detachable sealing structure facilitate production assembly and subsequent maintenance, reducing after-sales costs; high space utilization; the water channel does not occupy extra interior space and does not affect the appearance of the door panel or passenger use; strong versatility; the structure can be adapted to different vehicle front door panel platforms, making it easy to achieve platformization and standardization design.
