Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically to a door corner structure, a door sealing assembly, a door, and a vehicle. Background Technology

[0002] Cars equipped with frameless doors are increasingly popular due to their stylish appearance. A frameless door includes a door corner structure, a glass panel, and corner seals mounted on the corner structure. The corner structure has a lift channel along which the glass can rise or fall. When the glass is raised and the frameless door is closed, the corner seals come into contact with the seals at the bottom of the door frame, thus sealing the corner structure against the door frame. Simultaneously, the glass also contacts the seals at the top of the door frame, achieving a seal between the glass and the door frame. However, because a step is formed between the glass and the upper end of the lift channel, and the seals on the door frame cannot effectively seal this step, water can seep into the car through it.

[0003] In related technologies, to prevent water seeping into the car from dripping onto the floor inside the car, a water-guiding flange is usually installed on the corner structure of the door. The groove formed by the water-guiding flange guides the water that leaks into the car to the gap between the corner seal and the seal at the bottom of the door frame, so that the water seeps down through the gap to the door sill, thereby draining the water and preventing it from dripping into the vehicle.

[0004] However, water stains may remain on the corner seals and the seals at the bottom of the door frame, giving users the visual impression of water leakage when they open the frameless door, thus reducing the user experience. Summary of the Invention

[0005] This invention provides a door corner structure, a door sealing assembly, a door, and a vehicle, to at least solve the technical problem in related technologies where water stains remain on the corner seals and the seals at the bottom of the door frame, thus creating a visual impression of water leakage when the user opens the frameless door, thereby reducing the user experience. The technical solution of this application is as follows:

[0006] According to a first aspect of this application, a door corner structure is provided, including a body, a corner seal, and a water guide. The body has a lifting channel for raising and lowering the vehicle glass. The corner seal is connected to the body and located on the side of the lifting channel away from the vehicle glass. A first sealing channel is formed within the corner seal, which is used for sealing contact with the door frame. The water guide is connected to the body and located on the side of the body closer to the door frame. A water guide channel is formed on the water guide and communicates with the first sealing channel. The water guide channel is used to guide liquid that has seeped between the body and the door frame into the first sealing channel.

[0007] Using the aforementioned technical means, water that seeps into the vehicle can enter the water guiding channel. Since the water guiding channel is connected to the first sealing channel, the water can enter the first sealing channel and then be discharged to the outside of the vehicle. This prevents water from dripping onto the floor inside the vehicle, improving the user experience.

[0008] Because the water drainage process utilizes the sealing channel (first sealing channel) formed inside the vehicle's built-in seals (corner seals), water stains will not be visible on the surfaces of the corner seals and door seals when the car door is opened, thus improving the user's visual experience and further enhancing the user experience.

[0009] In one possible implementation, the main body has a connecting channel, the first end of which is connected to the water guiding channel, and the second end of which is connected to the first sealing channel.

[0010] According to the above-mentioned technical means, by opening a connecting channel on the main body, the water guiding channel and the first sealing channel are connected by the connecting channel, thereby realizing water guiding.

[0011] In one possible implementation, the door corner structure also includes a water guide pipe, the first end of which is connected to a water guide channel, and the second end of which extends into a first sealing channel to guide liquid into the first sealing channel.

[0012] Based on the above technical means, by setting up a water guide pipe, the water guide channel and the first sealing channel are connected by the water guide pipe, thereby realizing water guidance. The position of the water guide pipe can be set arbitrarily, so there is no need to change the shape, thickness, etc. of the body, making it more versatile.

[0013] In one possible implementation, the water guide is provided with a through hole, the first end of the through hole is connected to the water guide channel, and the first end of the water guide pipe extends into the through hole through the second end of the through hole; the door corner structure also includes a sealing part, which is connected to the outer wall of the water guide pipe, and the sealing part is at least partially located in the through hole and makes sealing contact with the inner wall of the through hole.

[0014] According to the above technical means, the first end of the water pipe is connected to the water channel through the through hole, and the water pipe is sealed in the through hole by the sealing part to ensure that water can smoothly enter the water pipe and prevent water from flowing to other places, thereby improving the water guiding performance.

[0015] In one possible implementation, a protrusion is also included, which is connected to the inner wall of the through hole and located between the water guide pipe and the inner wall of the through hole, in a direction from the first end of the through hole to the second end of the through hole. The sealing part and the protrusion are arranged in sequence and in contact.

[0016] Based on the aforementioned technical means, the water pipe can be detachably installed within the through hole using the protrusion, thus facilitating its removal when needed. When installing the water pipe, simply insert the second end of the water pipe into the through hole from the first end, allowing the sealing part to contact the protrusion, thereby achieving installation.

[0017] In one possible implementation, along the extension direction of the through hole, the distance between the side surface of the protrusion near the first end of the through hole and the first end of the through hole is equal to the size of the sealing portion.

[0018] The aforementioned technical means ensure that the end face of the first end of the water guide pipe is flush with the surface of the first end of the through hole in the water guide channel. This allows water to directly enter the water guide pipe through the first end when it converges at the through hole, preventing water from entering the through hole and thus avoiding water seepage into the gap between the sealing part and the inner wall of the through hole. This further improves the sealing performance and prevents water from being guided to other locations.

[0019] In one possible implementation, the sealing portion surrounds the extension direction of the water pipe; and / or, the protrusion surrounds the extension direction of the water pipe.

[0020] Based on the above technical means, the stability of the first end of the water guide pipe set in the through hole is improved, and the sealing performance between the water guide pipe and the inner wall of the through hole is also improved.

[0021] In one possible implementation, the fastener is connected to the first sealing channel, and the fastener has a fixing hole, into which the water pipe extends.

[0022] Based on the above technical means, the water guide pipe can be stably installed in the first sealed channel by using a fixing component, so as to avoid collision between the water guide pipe and the first sealed channel and reduce noise.

[0023] In one possible implementation, the outer peripheral wall of the water guide pipe contacts the inner peripheral wall of the fixing hole.

[0024] The aforementioned technical methods allow the water pipe to be securely held within the fixing hole, thereby further improving the stability of the water pipe installation and reducing noise.

[0025] In one possible implementation, the extension direction of the portion of the water pipe extending into the first sealing channel is consistent with the extension direction of the first sealing channel. The fixing member is rotatable relative to the first sealing channel between a first position and a second position. In the first position, the extension direction of the fixing hole is consistent with the extension direction of the first sealing channel, and the water pipe extends into the fixing hole. In the second position, the extension direction of the fixing hole forms an angle A with the extension direction of the first sealing channel, where 0° < A ≤ 90°.

[0026] Based on the aforementioned technical means, during the processing of the fixing plate, the extension direction of the fixing hole does not need to be considered, which facilitates processing. During the installation stage, when the water guide pipe is inserted into the fixing hole, the extension direction of the fixing hole is aligned with the extension direction of the portion of the water guide pipe extending into the first sealing channel, thus facilitating the insertion of the water guide pipe into the fixing hole.

[0027] In one possible implementation, the water guide includes a water guide flange that extends from the edge of the body toward the vehicle glass to form a water guide channel.

[0028] According to the above technical means, a water-guiding channel with an opening facing the car glass is formed between the water-guiding flange and the main body. The water-guiding flange intercepts the liquid that seeps in from the gap between the main body and the door frame, and then guides the liquid into the first sealed channel, thereby realizing water guidance and drainage.

[0029] According to a second aspect provided in this application, a door sealing assembly is provided, including a door corner structure and a door seal, wherein the door corner structure is the door corner structure described above; a second sealing channel is formed on the door seal, a first sealing channel is connected to a first end of the second sealing channel, and the second sealing channel is used to communicate with the outside of the vehicle.

[0030] The aforementioned technical means enable water in the water pipe within the first sealed channel to enter the second sealed channel, thus making the drainage path more concealed and preventing external noise from entering the vehicle through the drainage path, thereby reducing noise inside the vehicle.

[0031] In one possible implementation, the first end of the second sealing channel extends into the first sealing channel, and the second end of the water guide pipe on the door corner structure extends into the second sealing channel.

[0032] Based on the above technical means, water in the water pipe can directly enter the second sealed channel, avoiding water accumulation at the connection between the first and second sealed channels, thereby improving the drainage effect.

[0033] According to a third aspect provided in this application, a vehicle door is provided, including a door sheet metal assembly, a door sealing assembly, and a vehicle glass, wherein the door sealing assembly is the aforementioned door sealing assembly and is connected to the door sheet metal assembly; the vehicle glass is connected to the door sheet metal assembly.

[0034] Using the aforementioned technical means, the door sealing assembly is installed on the door sheet metal assembly to achieve a seal between the door sheet metal assembly and the door frame.

[0035] According to the fourth aspect provided in this application, a vehicle is provided, including a door.

[0036] The aforementioned technical methods achieve the same beneficial effects as described above, and will not be elaborated upon here.

[0037] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0038] (1) Since the sealing channel (first sealing channel) formed inside the vehicle’s own seal (corner seal) is used during the water diversion process, water stains will not be seen on the surface of the corner seal and the door seal when the car door is opened, thus improving the user experience.

[0039] (2) By opening a connecting channel on the main body, the water guiding channel and the first sealing channel are connected by the connecting channel to achieve water guiding.

[0040] (3) Use a water pipe to connect the water channel and the first sealing channel to achieve water delivery. The position of the water pipe can be set arbitrarily, so there is no need to change the shape, thickness, etc. of the body, making it more versatile.

[0041] (4) Use the through hole to connect the first end of the water pipe to the water channel, and use the sealing part to seal the water pipe in the through hole to ensure that water can smoothly enter the water pipe and prevent water from flowing to other places, so as to improve the water guiding performance.

[0042] (5) Facilitates the installation and disassembly of the water pipe.

[0043] (6) While improving drainage efficiency, further improve sealing performance to prevent water from being guided to other locations.

[0044] (7) Improve the stability of the first end of the water guide pipe in the through hole, and at the same time improve the sealing performance between the water guide pipe and the inner wall of the through hole.

[0045] (8) Fixing components can be used to ensure that the water pipe is stably installed in the first sealed channel, thereby avoiding collision between the water pipe and the first sealed channel and reducing noise.

[0046] (9) This allows the water pipe to be secured within the fixing hole, thereby further improving the stability of the water pipe installation and reducing noise.

[0047] (10) Facilitates the processing of fixing holes and the installation of water pipes.

[0048] (11) A trough-shaped water channel is formed by using the water-guiding flange, and water is collected and guided through the trough opening of the water-guiding channel.

[0049] It should be noted that the technical effects of any of the implementation methods in the second to fourth aspects can be found in the technical effects of the corresponding implementation methods in the first aspect, and will not be repeated here.

Detailed Implementation

[0065] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0066] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0067] As people's living standards improve, cars have become a convenient means of transportation widely used in daily life. People can use cars to go out to work, travel, and so on.

[0068] Based on this, this application provides a vehicle, which may be a sedan, bus, etc. The vehicle includes a door and a door frame, wherein the door frame is formed on the vehicle body, the door is mounted on the door frame, and the door can move relative to the door frame, such as by rotating.

[0069] By installing doors on the vehicle body, users can enter or exit the vehicle body by opening the doors, and close the doors to keep the vehicle in a closed state, thereby ensuring the safety of people or objects inside the vehicle body.

[0070] Based on this, such as Figure 1 As shown, the aforementioned car door 1 mainly includes a door sheet metal assembly 11, a door sealing assembly 12, and a car glass 13. The door sheet metal assembly 11 is connected to the door frame, for example, hinged to the door frame. The door sealing assembly 12 is connected to the door sheet metal assembly 11, for example, mainly connected to the peripheral wall surface of the door sheet metal assembly 11. The car glass 13 is connected to the door sheet metal assembly 11, and the car glass 13 can be raised and lowered relative to the door sheet metal assembly 11.

[0071] With the above configuration, the door sheet metal assembly 11 can support the vehicle glass 13. When the user needs to open the vehicle glass 13, they can lower the vehicle glass 13 to connect the interior and exterior of the vehicle, thereby exchanging the air inside the vehicle. When the user needs to close the vehicle glass 13, they can raise the vehicle glass 13 to isolate the interior and exterior of the vehicle.

[0072] Additionally, when the door 1 is closed, the door sealing assembly 12 seals the door sheet metal assembly 11 to the door frame, improving sealing performance and reducing noise inside the vehicle. Furthermore, the seal between the door sealing assembly 12 and the door frame prevents rainwater from seeping into the vehicle interior during rainy weather.

[0073] In order to ensure the sealing performance of door 1, such as Figure 1 As shown, a door frame sealing strip 2 is also installed on the door frame, so that the door sealing assembly 12 and the door frame sealing strip 2 can be sealed together to ensure the sealing performance of the door 1.

[0074] It is understandable that, in order for the vehicle glass 13 to be raised and lowered relative to the door sheet metal assembly 11, a receiving space for accommodating the vehicle glass 13 can be provided on the door sheet metal assembly 11, and a lifting hole communicating with the receiving space can be provided on the upper part of the door sheet metal assembly 11, so that the vehicle glass 13 can descend through the lifting hole to enter the receiving space, or rise to leave the receiving space. This achieves the raising and lowering of the vehicle glass 13.

[0075] In some embodiments, to prevent external water from seeping into the interior (accommodation space) of the door sheet metal assembly 11 through the gap between the vehicle glass 13 and the inner wall of the lift hole, such as... Figure 1As shown, the vehicle door 1 in this application also includes an outer door clamping strip 14, which is disposed at the edge of the lift hole and located on the outside of the vehicle glass 13. When the vehicle glass 13 is raised, the outer door clamping strip 14 contacts the outer surface of the vehicle glass 13, thereby sealing the gap between the vehicle glass 13 and the inner wall of the lift hole. This prevents water from entering the interior of the door sheet metal assembly 11, thus protecting the internal components of the door sheet metal assembly 11 from damage.

[0076] Meanwhile, the door outer clamp 14 can also provide support for the vehicle glass 13 to prevent the vehicle glass 13 from shaking.

[0077] In related technologies, car doors 1 generally include two types: framed doors and frameless doors. As the name suggests, a framed door refers to a door 1 with a frame at the top. When the car glass 13 is closed, the edge of the car glass 13 can extend into the sealing strip inside the frame. After the car door 1 is closed, the frame seals with the sealing strip on the door frame. Thus, the car glass 13 and the door frame have at least two layers of sealing, which can ensure the sealing performance between the car glass 13 and the door frame, reduce noise inside the vehicle, and prevent water from seeping into the vehicle interior through the gap between the car glass 13 and the door frame.

[0078] Frameless doors refer to doors without a frame above them, which makes the overall appearance of the door 1 look cleaner and more stylish. Therefore, installing frameless doors on the door frame can enhance the overall appearance of the vehicle, and has thus gradually become a popular choice.

[0079] When the door 1 in this application is a frameless door, in order to seal the door sheet metal assembly 11 and the door frame using the door sealing assembly 12, and to seal the glass 13 and the door frame using the door sealing assembly 12, such as Figure 1 , Figure 2 As shown, the door sealing assembly 12 in this application includes a door corner structure 121 and a door seal 122. The door corner structure 121 is connected to the door sheet metal assembly 11 and is located at the junction of the glass 13 and the door sheet metal assembly 11. A lifting channel 12111 is formed on the door corner structure 121. The edge of the glass 13 extending along the lifting direction of the lifting channel 12111 extends into the lifting channel 12111, so that the inner wall of the lifting channel 12111 can seal the edge of the glass 13 extending into it. The door seal 122 is arranged around the circumference of the door sheet metal assembly 11 to seal the door sheet metal assembly 11 and the door frame.

[0080] The sealing between the vehicle glass 13 and the door frame, as well as the sealing between the door sheet metal assembly 11 and the door frame, are achieved by setting the door corner structure 121 and the door seal 122.

[0081] However, as Figure 1 As shown, since the edge of the vehicle glass 13 extending along its lifting direction extends into the lifting channel 12111, a step will be formed on the inner side of the door corner structure 121 when the vehicle glass 13 is raised. Figure 1 (The position of the line within the dashed box at point A) Even if the car glass 13 is sealed on the door frame, the presence of the step will still create a gap at the intersection of the car glass 13, the door frame, and the door corner structure 121. This will allow external water to seep into the vehicle interior through the gap between the door corner structure 121 and the door frame, thus affecting the user experience.

[0082] Based on this, in a related technology, such as Figure 3 As shown, the above problems were not taken into account, and therefore no countermeasures were taken. As a result, water seeped into the vehicle through the gaps and dripped onto the floor inside the vehicle.

[0083] In another related technology, such as Figure 4 As shown, in order to solve the above problem, the door corner structure 121 is close to the door frame ( Figure 4 A water-guiding lip 15 is provided on one side surface of the door frame sealing strip 2. The water-guiding lip 15 bends towards the vehicle glass 13 to form a water-guiding channel. A water-guiding channel is formed from top to bottom on the outer surface of the door corner structure 121. Water that seeps into the space between the door corner structure 121 and the door frame is guided into the water-guiding channel and then guided to the door sill. This prevents water that has seeped into the vehicle interior from dripping further onto the floor inside the vehicle.

[0084] However, since the water channel is located on the outer surface of the door corner structure 121, water stains can still be seen on the door corner structure 121 (at the water channel) after the user opens the door 1. This gives the user a visual feeling of water leakage, which affects the user experience.

[0085] Based on this, such as Figure 2 , Figure 5 As shown, the door corner structure 121 provided in this application includes a body 1211, a corner seal 1212, and a water guide 1213. A lifting channel 12111 is formed on the body 1211 and is used for lifting the vehicle glass 13. The corner seal 1212 is connected to the body 1211 and is located in the lifting channel 12111 away from the vehicle glass 13. Figure 2On one side (not shown), a first sealing channel 12121 is formed within the corner seal 1212, which is used for sealing contact with the door frame. A water guide 1213 is connected to the body 1211 and located on the side of the body 1211 closest to the door frame. A water guide channel 12131 is formed on the water guide 1213, which communicates with the first sealing channel 12121. The first sealing channel 12121 communicates with the first end of the second sealing channel 1221, which communicates with the outside of the vehicle. The water guide channel 12131 is used to guide liquid that has seeped between the body 1211 and the door frame into the first sealing channel 12121.

[0086] With the above configuration, water seeping into the vehicle can enter the water guiding channel 12131. Since the water guiding channel 12131 is connected to the first sealing channel 12121, and the first sealing channel 12121 is connected to the first end of the second sealing channel 1221, water can enter the first sealing channel 12121, then the second sealing channel 1221, and finally be discharged to the outside of the vehicle. This prevents water from dripping onto the floor inside the vehicle, thereby improving the user experience.

[0087] Because the water drainage process utilizes the sealing channels (first sealing channel 12121 and second sealing channel 1221) formed inside the vehicle's built-in seals (corner seal 1212 and door seal 122), water stains will not be visible on the surfaces of the corner seal 1212 and door seal 122 when the door 1 is opened, thus improving the user experience.

[0088] Furthermore, since the first sealing channel 12121 and the second sealing channel 1221 are located on the door sealing assembly 12, and the shape of the door sealing assembly 12 is relatively tortuous, the paths of the first sealing channel 12121 and the second sealing channel 1221 are more enclosed and tortuous. This can prevent external sound from being transmitted to the vehicle interior through the first sealing channel 12121 and the second sealing channel 1221, thereby reducing the noise inside the vehicle.

[0089] In order to connect the second sealing channel 1221 with the outside of the vehicle, a water leakage hole is opened at the position of the door seal 122 near the bottom of the vehicle. This allows water entering the second sealing channel 1221 to flow downward to the water leakage hole, and then flow out through the water leakage hole, and finally flow to the ground.

[0090] Compared to related technologies where water is guided to a water channel on the surface of the corner seal 1212 and then to the door sill, the solution in this application directly guides water to the ground through the drain hole, which can prevent water from accumulating at the door sill. When the user opens the door 1, there will be no problem of a large amount of water accumulating at the door sill, further improving the user experience.

[0091] In order to form water guiding channel 12131, such as Figure 2 As shown, the aforementioned water guide 1213 includes a water guide flange 12132. The edge of the water guide flange 12132, away from the body 1211, extends towards the vehicle glass 13 to form a water guide channel 12131. The water guide flange 12132 and the body form an opening facing the vehicle glass 13, and the water guide flange 12132 intercepts liquid seeping into the gap between the body 1211 and the door frame, thereby guiding the liquid into the first sealed channel 12121, thus achieving water guiding and drainage.

[0092] It is understandable that the water guiding channel 12131 should have a certain length along the width direction of the vehicle glass 13 (perpendicular to the lifting direction of the vehicle glass 13). In this way, even if the water flows a certain distance along the edge formed by the vehicle glass 13 and the body 1211 before moving to the position of the water guiding channel 12131, it can be ensured that the water guiding channel 12131 can intercept the water, thereby better guiding the water into the first sealing channel 12121.

[0093] The water-guiding flange 12132 can be integrally formed with the body 1211, which can improve the overall structural strength of the body 1211 and the water-guiding flange 12132, and also avoid secondary processing and reduce processing steps. Of course, the body 1211 and the water-guiding flange 12132 can also be separate structures, with the body 1211 and the water-guiding flange 12132 processed separately, and then fixed together by any suitable method such as adhesive bonding.

[0094] In some embodiments, such as Figure 2 As shown, the aforementioned door corner structure 121 also includes a baffle plate 1218, which is connected to the body 1211. Along the lifting direction of the car glass 13, the baffle plate 1218 extends from the upper edge of the lifting channel 12111 to the water inlet end of the water guide channel 12131.

[0095] By setting up the baffle plate 1218, water flowing at an angle on the side surface of the body 1211 near the door frame sealing strip 2 can be intercepted. This allows the water to be better poured into the water channel 12131, preventing water droplets from falling onto the floor inside the vehicle.

[0096] Alternatively, the water guide 1213 may also include a pipe, with a water channel 12131 formed inside the pipe, such that one end of the pipe faces the edge formed by the vehicle glass 13 and the body 1211, and the other end of the channel communicates with the first sealing channel 12121. This allows water that has seeped into the vehicle interior to flow into the first sealing channel 12121 through the pipe.

[0097] Understandably, in this case, the size of the opening at the end of the pipe should meet the water guiding requirements, allowing water to enter the pipe through the end.

[0098] In some embodiments, in order to guide water in the water guiding channel 12131 to the first sealing channel 12121, a connecting channel can be formed on the body 1211. The first end of the connecting channel is connected to the water guiding channel 12131, and the second end of the connecting channel is connected to the first sealing channel 12121. In this way, water entering the water guiding channel 12131 can enter the connecting channel, then enter the first sealing channel 12121, and finally be discharged to the outside of the vehicle.

[0099] It is understood that the connection channel can be opened at any suitable location on the main body 1211, and the specific location can be set according to the shape of the main body 1211. In order to facilitate the opening of the connection channel, the main body 1211 should have a certain thickness at the location where the connection channel is opened, so as to meet the opening requirements of the main body 1211.

[0100] In other embodiments, in order to guide water in the water channel 12131 to the first sealing channel 12121, such as Figure 5 As shown, the door corner structure 121 provided in this application also includes a water guide pipe 1214. The first end of the water guide pipe 1214 is connected to the water guide channel 12131, and the second end of the water guide pipe 1214 extends into the first sealing channel 12121 to guide liquid into the first sealing channel 12121. By providing the water guide pipe 1214, water in the water guide channel 12131 is guided into the first sealing channel 12121, thereby achieving water guidance.

[0101] Since the water pipe 1214 is independent of the main body 1211, the setting of the water pipe 1214 does not need to take into account the structure and size of the main body 1211. Thus, the main body 1211 does not need to be modified because of the setting of the water pipe 1214. Modification can be made on the basis of the original main body 1211, which can reduce the difficulty of processing and modification.

[0102] It is understandable that the shape of the water pipe 1214 can be adjusted according to the position of the water channel 12131 and the position of the corner seal 1212.

[0103] The water conduit 1214 can be made of thermoplastic vulcanizate (TPV). TPV material has excellent resilience and compression set, as well as aging resistance. When TPV material is used for the water conduit 1214, it will not break even after prolonged bending, ensuring its service life and reducing the frequency of replacement. Of course, the water conduit 1214 can also be made of any other suitable material.

[0104] Based on this, when opening car door 1, to avoid the water pipe 1214 appearing in the user's field of vision, such as... Figure 5 As shown, when the second end of the water guide pipe 1214 is connected to the first sealing channel 12121, the middle part of the water guide pipe 1214 is located on the side of the corner seal 1212 near the vehicle glass 13. This allows the second end of the water guide pipe 1214 to pass through the side panel of the corner seal 1212 facing the vehicle glass 13 and extend into the first sealing channel 12121. In this way, the water guide pipe 1214 can be covered by the body 1211 and the corner seal 1212, preventing the water guide pipe 1214 from appearing in the user's field of vision when the car door 1 is opened, thereby improving the overall appearance of the car door 1.

[0105] Based on this, in order to connect the first sealing channel 12121 with the second sealing channel 1221, the first end of the second sealing channel 1221 extends into the first sealing channel 12121 and connects with it. This ensures the sealing performance at the connection between the corner seal 1212 and the door seal 122.

[0106] Based on this, since the first end of the second sealing channel 1221 extends into the first sealing channel 12121, and since the channel wall of the second sealing channel 1221 has a certain thickness, a step surface will be formed between the end face of the first end of the second sealing channel 1221 and the inner wall of the first sealing channel 12121. In order to allow the water in the water guide pipe 1214 to flow smoothly into the second sealing channel 1221, the second end of the water guide pipe 1214 extends into the second sealing channel 1221.

[0107] In this way, the water in the water pipe 1214 can flow directly into the second sealing channel 1221, which can prevent water droplets from falling on the step surface formed between the end face of the first end of the second sealing channel 1221 and the inner wall of the first sealing channel 12121, thus enhancing the drainage effect.

[0108] Of course, the second end of the water pipe 1214 can also simply extend into the first sealing channel 12121, so that the water in the water pipe 1214 first flows into the first sealing channel 12121 and then flows into the second sealing channel 1221, thereby achieving drainage.

[0109] In order to connect the first end of the water pipe 1214 with the water channel 12131, such as Figure 6 As shown, a through hole 12133 is provided on the water guide 1213. The first end of the through hole 12133 is connected to the water guide channel 12131, and the first end of the water guide pipe 1214 extends into the through hole 12133 through the second end of the through hole 12133. Figure 7 , Figure 8 As shown, the door corner structure 121 provided in this application also includes a sealing part 1215. The sealing part 1215 is connected to the outer wall of the water guide pipe 1214. The sealing part 1215 is at least partially located in the through hole 12133 and is in sealing contact with the inner wall of the through hole 12133.

[0110] By opening a through hole 12133 in the water guide 1213, and since the first end of the through hole 12133 is connected to the water guide channel 12131, and the first end of the water guide pipe 1214 is located inside the through hole 12133, water in the water guide channel 12131 can flow through the through hole 12133 to the first end of the water guide pipe 1214, and then flow through the water guide pipe 1214 to the first sealed channel 12121. This achieves drainage.

[0111] Meanwhile, since the sealing part 1215 is in sealed contact with the inner wall of the through hole 12133, the presence of the sealing part 1215 can prevent water from flowing away through the gap between the water guide pipe 1214 and the inner wall of the through hole 12133. This prevents water from flowing to other places and enhances the drainage effect.

[0112] In order to ensure that the water in the water guiding channel 12131 flows smoothly to the through hole 12133, the through hole 12133 should be located at the lowest point of the water guiding channel 12131. Since water flows to lower places, setting the through hole 12133 at the lowest point can make the water quickly gather at the through hole 12133, thereby improving the drainage efficiency.

[0113] Furthermore, the sealing part 1215 can surround the extension direction of the water guide pipe 1214, thus sealing one circumference of the water guide pipe 1214. This provides a better sealing effect, allowing water to flow only through the water guide pipe 1214 into the first sealing channel 12121.

[0114] Alternatively, the sealing part 1215 may not wrap around the extension direction of the water pipe 1214.

[0115] In some embodiments, to stably position the first end of the water guide pipe 1214 within the through hole 12133, the first end of the water guide pipe 1214 can be fixedly connected to the inner wall of the through hole 12133, thereby ensuring the stability of the water guide pipe 1214. Thus, even if the vehicle shakes during operation, the first end of the water guide pipe 1214 can remain stably positioned within the through hole 12133, preventing the first end of the water guide pipe 1214 from shaking and ensuring that water can smoothly enter the water guide pipe 1214.

[0116] Or, such as Figure 9 , Figure 10 As shown, the door corner structure 121 provided in this application also includes a protrusion 1216. The protrusion 1216 is connected to the inner wall of the through hole 12133 and is located between the water guide pipe 1214 and the inner wall of the through hole 12133. The direction is from the first end of the through hole 12133 to the second end of the through hole 12133. The sealing part 1215 and the protrusion 1216 are arranged in sequence and are in contact.

[0117] By providing a protrusion 1216 on the inner wall of the through hole 12133, the sealing part 1215 can be detachably installed in the through hole 12133 using the protrusion 1216. Thus, when needed, such as when the water pipe 1214 is damaged and needs to be replaced, the water pipe 1214 can be removed, which facilitates the replacement of the water pipe 1214.

[0118] Specifically, when it is necessary to remove the water guide pipe 1214, the water guide pipe 1214 is removed from the through hole 12133 in the direction from the second end of the through hole 12133 to the first end of the through hole 12133. When installing the water guide pipe 1214 into the through hole 12133, the water guide pipe 1214 is inserted into the through hole 12133 in the direction from the first end of the through hole 12133 to the second end of the through hole 12133, so that the sealing part 1215 contacts the protrusion 1216, thereby realizing the installation of the water guide pipe 1214.

[0119] The protrusion 1216 can be arranged around the extension direction of the water guide pipe 1214, thus providing support for the sealing part 1215 along the circumference of the water guide pipe 1214, thereby allowing the water guide pipe 1214 to be more stably installed in the through hole 12133. Of course, the protrusion 1216 may not be arranged around the extension direction of the water guide pipe 1214.

[0120] For example, the protrusion 1216 includes a plurality of sub-protrusions, which are spaced around the water pipe 1214 so that the sealing part 1215 contacts the plurality of sub-protrusions to provide support for the sealing part 1215 using the plurality of sub-protrusions.

[0121] In some embodiments, the protrusion 1216 surrounds the extension direction of the water guide pipe 1214, and the sealing portion 1215 also surrounds the extension direction of the water guide pipe 1214. This not only allows the protrusion 1216 to more stably position the water guide pipe 1214 within the through hole 12133, but also allows the sealing portion 1215 to better seal the water guide pipe 1214 and the inner wall of the through hole 12133. This improves the water guiding efficiency of the water guide pipe 1214.

[0122] To further improve the sealing performance between the water pipe 1214 and the through hole 12133, the sealing part 1215 and the protrusion 1216 are made into a sealing contact. This way, even if water leaks through the gap between the sealing part 1215 and the inner wall of the through hole 12133, the seal between the protrusion 1216 and the sealing part 1215 can prevent further water flow. This further improves the sealing performance between the water pipe 1214 and the through hole 12133.

[0123] In order to allow water in the water channel 12131 to smoothly enter the water pipe 1214 through the first end of the water pipe 1214, along the extension direction of the through hole 12133, the distance between the side surface of the protrusion 1216 near the first end of the through hole 12133 and the first end of the through hole 12133 is equal to the size of the sealing part 1215.

[0124] With the above configuration, the end face of the first end of the water guide pipe 1214 is flush with the inner wall of the water guide channel 12131. This allows water, after converging at the through hole 12133, to directly enter the water guide pipe 1214 through the first end, preventing water from entering the through hole 12133 and thus preventing water from seeping into the gap between the sealing part 1215 and the inner wall of the through hole 12133. This further improves the sealing performance, preventing water from being guided to other locations and increasing water guiding efficiency.

[0125] During vehicle operation, shaking may occur. To prevent the water pipe 1214 from shaking within the first sealed channel 12121, such as... Figure 11 , Figure 12 As shown, the door corner structure 121 provided in this application also includes a fixing member 1217. The fixing member 1217 is connected in the first sealing channel 12121. A fixing hole 12171 is provided on the fixing member 1217, and the water guide pipe 1214 extends into the fixing hole 12171.

[0126] By setting a fixing member 1217 in the first sealed channel 12121 and opening a fixing hole 12171 on the fixing member 1217, the water pipe 1214 is stably set in the first sealed channel 12121 using the fixing hole 12171, thereby preventing the water pipe 1214 from shaking during vehicle operation, reducing noise inside the vehicle, and improving user experience.

[0127] Alternatively, the water pipe 1214 can be directly fixed inside the first sealing channel 12121 by means of screw fastening.

[0128] To further improve the stability of the water guide pipe 1214, the outer peripheral wall of the water guide pipe 1214 is made to contact the inner peripheral wall of the fixing hole 12171. In this way, when the water guide pipe 1214 is inserted into the fixing hole 12171, the fixing hole 12171 can firmly lock the water guide pipe 1214 inside, thereby further improving the stability of the water guide pipe 1214. This avoids collision between the water guide pipe 1214 and the first sealing channel 12121, reduces noise, and prevents water inside the water guide pipe 1214 from splashing everywhere.

[0129] Of course, the water guide pipe 1214 can also simply be located inside the water guide pipe 1214, with a certain gap between the outer peripheral wall of the water guide pipe 1214 and the inner peripheral wall of the fixing hole 12171.

[0130] To facilitate the insertion of the water pipe 1214 into the fixing hole 12171, such as Figure 11 , Figure 12 As shown, the extension direction of the portion of the water pipe 1214 extending into the first sealing channel 12121 is consistent with the extension direction of the first sealing channel 12121. The aforementioned fixing member 1217 is rotatable relative to the first sealing channel 12121 between a first position and a second position. In the first position, the extension direction of the fixing hole 12171 is consistent with the extension direction of the first sealing channel 12121. In the second position, the extension direction of the fixing hole 12171 forms an angle A with the extension direction of the first sealing channel 12121, where 0° < A ≤ 90°.

[0131] With the above configuration, when machining the fixing member 1217 and the fixing hole 12171, the extension direction of the fixing hole 12171 does not need to be considered, which facilitates machining and reduces machining difficulty. When it is necessary to insert the water guide pipe 1214 into the fixing hole 12171, first rotate the fixing member 1217 so that the extension direction of the fixing hole 12171 is consistent with the extension direction of the first sealing channel 12121. Since the extension direction of the part of the water guide pipe 1214 that extends into the first sealing channel 12121 is consistent with the extension direction of the first sealing channel 12121, the extension direction of the part of the water guide pipe 1214 that extends into the first sealing channel 12121 is consistent with the extension direction of the fixing hole 12171, which makes it easy to insert the water guide pipe 1214 into the fixing hole 12171.

[0132] The fastener 1217 and the body 1211 can be processed into an integral structure, which can not only increase the overall structural strength of the body 1211 and the fastener 1217, but also reduce the number of processing steps.

[0133] Alternatively, the fastener 1217 and the body 1211 can be processed into separate structures, with the body 1211 and the fastener 1217 processed separately, and then the two can be connected together by fastening methods such as adhesive bonding.

[0134] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
