Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a door sealing device. This application also relates to a door and a vehicle using this door sealing device. Background Technology

[0002] In automobiles, glass channels are functional components used to seal car doors. They are mainly made of composite materials such as rubber and polyurethane, and their core function is to achieve sealing, fixing, buffering, and guiding between the door glass and the mounting frame.

[0003] The existing glass channel in the triangular area of ​​the front door, after being installed on the door sheet metal, poses a risk of rainwater entering the vehicle from the outside during rainy days due to the structural design of the glass channel. Utility Model Content

[0004] In view of this, the present application aims to provide a door sealing device to prevent rainwater from entering the vehicle interior through the glass groove.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A door sealing device includes a glass groove that can be installed on a door; The glass groove has a groove on the side facing the door glass that allows the door glass to be inserted. The inner wall of the groove is provided with a first lip that abuts against the door glass. The upper part of the first lip is arranged vertically along the vertical direction of the whole vehicle.

[0006] Furthermore, the side of the glass groove facing the vehicle interior is provided with a sealing surface for the door frame sealing strip to abut against, the side of the sealing surface near the door glass is provided with a drainage structure, and the side of the sealing surface away from the door glass is provided with a water-blocking structure.

[0007] Furthermore, the water-blocking structure is a water-blocking boss that protrudes from the sealing surface onto the side inside the vehicle.

[0008] Furthermore, the side of the glass trough facing the interior of the vehicle is provided with a protrusion that extends into the interior of the vehicle; The groove is located on one side of the protrusion in the longitudinal direction of the vehicle. The drainage structure includes a drainage groove located on the other side of the protrusion in the front-rear direction of the vehicle, and a drainage hole located below the drainage groove.

[0009] Furthermore, a groove is provided on the side of the sealing surface near the drainage groove. The groove is recessed towards the outside of the vehicle along the left-right direction of the whole vehicle and extends with the drainage direction of the drainage groove.

[0010] Furthermore, the upper part of the drainage channel gradually slopes away from the door glass from the lower part.

[0011] Furthermore, the drainage hole is arranged through the glass groove along the left-right direction of the vehicle, and the bottom wall of the drainage hole gradually slopes downward from one end facing the inside of the vehicle to the other end.

[0012] Furthermore, a limiting part is provided on the side of the glass channel facing outwards from the vehicle. When the glass channel is installed on the door sheet metal, the limiting part can be inserted into the limiting hole on the door sheet metal, thereby limiting the installation position of the glass channel on the door sheet metal.

[0013] Compared with related technologies, this application has the following advantages: (1) The door sealing device described in this application limits the upper part of the first lip to be arranged vertically along the vertical direction of the whole vehicle, so that the step difference between the upper part of the first lip and the window glass is small, thereby making the gap between the glass groove and the door glass sealing strip and the window frame sealing strip smaller, which can better prevent water leakage from the upper part of the sealing groove of the vehicle, thereby improving the sealing performance of the glass groove.

[0014] (2) By setting a sealing surface on the door glass groove, and setting a drainage structure and a water-blocking structure on both sides of the sealing surface, the water-blocking structure can form the first line of defense, which can effectively prevent rainwater from entering the area where the sealing surface is located, while the drainage structure can serve as the second line of defense, so that a small amount of water entering the sealing surface area can be discharged through the drainage structure, thereby effectively preventing rainwater from entering the vehicle.

[0015] (3) By setting the water-blocking structure as a water-blocking protrusion, the interference between the glass groove and the door glass can be increased, so that the water-blocking protrusion can better prevent rainwater from entering the sealing surface area.

[0016] (4) A protrusion is provided in the door glass groove to facilitate the arrangement of the drainage structure. By setting the drainage structure as a drainage groove and a drainage hole, the drainage groove can better guide the water flow into the sealing surface area to the drainage hole for discharge, thereby better preventing the water flow into the sealing surface area from entering the vehicle.

[0017] (5) By setting a groove on the side of the sealing surface near the drainage groove, and limiting the concave direction and extension direction of the groove, the water flow can be better guided by the drainage groove and the groove, and the water flow entering the sealing surface area can be better discharged through the drainage structure, thereby effectively reducing the risk of rainwater entering the vehicle.

[0018] (6) The drainage channel is tilted and the drainage channel is limited to gradually tilting away from the door glass from the top to the bottom, which can change the direction of water flow and effectively reduce the risk of rainwater entering the car.

[0019] (7) The drainage hole runs through the glass groove along the left and right direction of the whole vehicle, while limiting the inclination direction of the bottom wall of the drainage hole, so that the water flow can be guided to the outside of the vehicle through the drainage hole, effectively preventing rainwater from entering the vehicle.

[0020] (8) The limiting part provided on the door glass groove is beneficial to improving the assembly efficiency of the glass groove when the door glass is installed on the door sheet metal, and at the same time, it is beneficial to improve the installation accuracy of the glass groove on the door sheet metal.

[0021] Another objective of this application is to provide a car door, which is a frameless car door, and the frameless car door is provided with the car door sealing device as described above.

[0022] The vehicle door described in this application, by applying the above-mentioned door sealing device, can effectively prevent rainwater from entering the vehicle through the glass groove in rainy weather, thereby improving the sealing performance and quality of the door.

[0023] Another object of this application is to provide a vehicle having doors as described above.

[0033] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0034] An embodiment of the first aspect of this application provides a glass trough, which improves the leakage problem in the glass trough area by improving the shape and structure of the glass trough itself, thereby improving the sealing performance between the glass trough and the glass and the door frame.

[0035] In related technologies, in automobiles, glass grooves are functional accessories used to seal car doors. They are mainly made of composite materials such as rubber and polyurethane, and their core function is to achieve sealing, fixing, buffering, and guiding between the door glass and the mounting frame.

[0036] The existing glass channel in the triangular area of ​​the front door, after being installed on the door sheet metal, poses a risk of rainwater entering the vehicle from the outside during rainy days due to the structural design of the glass channel.

[0037] After numerous experiments and analyses, the inventors discovered a risk of water leakage at the interface between the glass channel and the door glass. Specifically, on frameless doors, water is prone to entering the upper part of the interface between the door glass and the glass channel.

[0038] In the triangular area of ​​the front door of a frameless car door, there is a mating part between the door glass and the glass channel because the door glass needs to be embedded in the channel. To prevent water from entering the mating part, the glass channel has a lip on both the inner and outer side walls of the window glass.

[0039] Specifically, the upper part of the lip on the inner wall curves slightly downward and backward, resulting in a step difference between the upper part of the lip on the inner wall and the transition position of the door glass. When this step difference is matched with the glass sealing strip and the door frame sealing strip, there is an unavoidable gap. Therefore, in rainy weather, rainwater may enter the car through this gap, resulting in the risk of water leakage.

[0040] Furthermore, existing car doors, especially frameless doors, have a first triangular hole structure at the junction of the glass groove, the door glass seal, and the glass, which can cause water to seep in. A second triangular hole structure can also be formed at the junction of the door frame seal, the glass groove, and the glass. Since the two triangular hole structures are on the same water flow path, this structural design allows water that has seeped between the first and second seals to seep into the interior of the cabin, affecting the customer's user experience.

[0041] In view of this, in order to overcome the shortcomings of the related technology, in this embodiment, the door sealing structure is preferably applicable to frameless car door models, especially to the front door. Moreover, this embodiment mainly uses the application of the door sealing structure to the front door of a frameless car door model as an example to introduce the relevant content.

[0042] In the sealing groove of this embodiment, combined with Figure 1 , Figure 2 and Figure 6 As shown, the overall design includes a glass groove 1 that can be installed on the door. The side of the glass groove 1 facing the door glass has a groove 101 into which the door glass can be inserted. The inner sidewall 1011 of the groove 101 is provided with a first lip 1013 that abuts against the door glass. The upper part of the first lip 1013 is arranged vertically along the vertical direction of the whole vehicle.

[0043] It should be noted that the glass groove 1 in this embodiment is the glass groove 1 in the front triangular area of ​​the front door of the vehicle. The attached figure is a schematic diagram of the glass groove 1 in the front triangular area of ​​the left front door of the vehicle. The structure of the glass groove 1 will be described in detail below with reference to the attached figure. The glass groove 1 of the right front door of the vehicle and the glass groove 1 of the left front door of the vehicle are symmetrical about the center line of the left and right direction of the vehicle, and will not be described in detail here.

[0044] The structural diagram of the car door glass is not shown. To better understand the glass groove 1 in this embodiment, please refer to... Figures 2 to 5As shown, the glass groove 1 faces the door glass on the side, that is, the rear side of the glass groove 1 in the front-rear direction of the whole vehicle.

[0045] The channel 101 is arranged vertically along the vertical direction of the vehicle. The front edge of the door glass in the front-rear direction of the vehicle is also arranged vertically along the vertical direction of the vehicle. The front edge of the door glass is embedded in the channel 101, so that the channel 101 can clamp and support the door glass. The channel 101 can improve the stability of the door glass lifting and lowering, as well as improve the sealing of the glass channel 1 and the glass overlap part.

[0046] It should be noted that any structural parts not mentioned in the door sealing structure of this embodiment can be referred to from various structures in the vehicle body structure known to those skilled in the art. For example, in related technologies, the side wall end of the vehicle body (the area corresponding to the door opening) is usually provided with a door glass sealing strip to form the first seal, the door opening of the vehicle body is usually provided with a door frame sealing strip to form the second seal, and the front corner area of ​​the door is usually provided with a glass groove 1.

[0047] In detail, still refer to Figures 2 to 5 As shown, in the left-right direction of the vehicle, the trough 101 has an inner wall 1011 located inside the door glass and an outer wall 1012 located outside the door glass.

[0048] The inner wall 1011 is provided with a first lip 1013, which abuts against the inner wall of the door glass on the outside side of the vehicle along the left-right direction of the whole vehicle. The outer wall 1012 is provided with a second lip 1014, which abuts against the outer wall of the door glass on the inside side of the vehicle along the left-right direction of the whole vehicle.

[0049] In the above implementation, the door sealing device limits the upper part of the first lip 1013 to be arranged vertically along the vertical direction of the whole vehicle, so that the step difference between the upper part of the first lip 1013 and the window glass is small, and the gap between the glass groove 1 and the door glass sealing strip and the window frame sealing strip is small, which can better prevent water leakage from the upper part of the sealing groove of the vehicle, thereby improving the sealing performance of the glass groove 1.

[0050] More specifically, along the front-rear direction of the vehicle, the top wall of the door glass gradually slopes downwards. Here, "top wall" refers to the upward-facing side wall of the door glass in the vertical direction of the vehicle. Figure 2 The glass groove 1 shown here slopes downwards from back to front along the front-rear direction of the vehicle. Here, the top wall of the glass groove 1 refers to the upward-facing side wall of the glass groove 1 in the vertical direction of the vehicle.

[0051] In a preferred embodiment, the top wall of the door glass and the top wall of the glass groove 1 have the same inclination angle. This arrangement can further reduce the step difference between the upper part of the first lip 1013 and the door glass, thereby reducing the gap between the glass groove and the mating part of the door glass sealing strip and the window frame sealing strip, and further preventing water leakage from the upper part of the vehicle's sealing groove.

[0052] In a preferred embodiment, the interference between the first lip 1013 and the door glass is, for example, between 0.4mm and 1.7mm, such as 0.4mm, 0.6mm, 1.0mm, 1.3mm, 1.7mm, etc., and the interference between the second lip 1014 and the door glass is, for example, between 1mm and 3.2mm, such as 1mm, 1.6mm, 2.1mm, 2.7mm, 3.2mm, etc.

[0053] It should be understood that limiting the interference between the first lip 1013 and the door glass, as well as the interference between the second lip 1014 and the door glass, can better prevent water leakage at the part of the groove 101 that clamps the door glass, and help ensure the sealing effect between the groove 101 and the door glass.

[0054] It should be noted that the top wall of the door glass and the top wall of the glass groove 1 need to be sealed with the door glass sealing strip (not shown in the figure), and the specific structure can be referred to in the prior art.

[0055] In some exemplary embodiments, the glass groove 1 has a sealing surface 102 on the side facing the vehicle interior for the door frame sealing strip to abut against, a drainage structure 103 on the side of the sealing surface 102 near the door glass, and a water-blocking structure 104 on the side of the sealing surface 102 away from the door glass.

[0056] In a preferred embodiment, reference is still made to Figure 2 As shown, the sealing surface 102 has a certain width, and along the front-rear direction of the vehicle, the sealing surface 102 gradually slopes downwards. This provides a good waterproof sealing effect.

[0057] It should be noted that the door frame sealing strip is not shown in the diagram. It is installed on the door frame, and its structure can refer to existing structures. The door frame sealing strip has a sealing lip that abuts against the sealing surface 102. Along the front-rear direction of the vehicle, the sealing lip of the door frame sealing strip gradually slopes downwards from back to front, and the slope direction of the sealing lip of the door frame sealing strip is consistent with the slope direction of the sealing surface 102. This ensures that when the door is closed, the sealing lip of the door frame sealing strip is precisely against the sealing surface 102 area, thereby achieving a better sealing effect.

[0058] In the above implementation, a sealing surface 102 is provided on the door glass groove 1, and a drainage structure 103 and a water-blocking structure 104 are respectively provided on both sides of the sealing surface 102. The water-blocking structure 104 can form a first line of defense, which can effectively prevent rainwater from entering the area where the sealing surface 102 is located, while the drainage structure 103 can serve as a second line of defense, allowing a small amount of water entering the area of ​​the sealing surface 102 to be discharged through the drainage structure 103, thereby effectively preventing rainwater from entering the vehicle.

[0059] In addition, the sealing surface 102, which presses against the window frame sealing strip, can also serve as a line of defense to prevent rainwater from entering the vehicle. The water-blocking structure 104 and the drainage structure 103 are placed on both sides of the sealing surface 102. The various lines of defense work together to form a multi-layered waterproof structure, which can better prevent rainwater from entering the vehicle during rainy weather.

[0060] Still refer to Figures 2 to 4 As shown, in some exemplary embodiments, the water-blocking structure 104 is a water-blocking boss that protrudes from the sealing surface 102 toward the interior side of the vehicle. Here, by setting the water-blocking structure 104 as a water-blocking boss, the interference between the glass groove 1 and the door glass can be increased, thereby enabling the water-blocking boss to better prevent rainwater from entering the sealing surface 102 area.

[0061] In one exemplary embodiment, the protrusion height of the water-retaining boss is at least 1 mm, such as 1 mm, 1.1 mm, 1.2 mm, etc., which has a good waterproof sealing effect. It should be understood that it is also feasible to set the protrusion height of the water-retaining boss to other values, such as 0.8 mm or 0.9 mm, but this will weaken the waterproof sealing effect of the water-retaining boss.

[0062] It should be noted that, in one exemplary embodiment, the water-blocking protrusion gradually slopes downward from rear to front along the front-rear direction of the vehicle, and the water-blocking protrusion extends along the curvature direction of the sealing surface 102, which can effectively prevent rainwater from entering the sealing surface 102 area and achieve a good waterproof sealing effect.

[0063] Continue to refer to Figures 2 to 4 As shown, in some exemplary embodiments, the glass channel 1 has a protrusion 105 protruding into the vehicle interior on the side facing the vehicle interior. The aforementioned groove 101 into which the front edge of the door glass is embedded is located on one side of the protrusion 105, and the drainage structure 103 includes a drainage groove 1031 located on the other side of the protrusion 105, and a drainage hole 1032 provided below the drainage groove 1031.

[0064] The drainage channel 1031 extends from top to bottom along a preset drainage path, so that the drainage channel 1031 can direct the water entering the sealed area to the drainage hole 1032 according to the preset drainage path.

[0065] It should be noted that the protrusion 105 and the water-blocking boss together form a sealing groove structure with the sealing surface 102. The upper opening of the sealing groove faces the rear side of the vehicle. In this embodiment, the drainage structure 103 is located at the bottom of the sealing groove, so that the water flowing into the sealing groove from the upper opening can be guided out by the drainage structure 103.

[0066] In one example, a drainage groove 1031 is provided at the intersection of the sealing surface 102 and the protrusion 105. A protrusion 1051 is provided on the side of the protrusion 105 facing away from the door glass. The protrusion 1051 and the sealing surface 102 form the aforementioned drainage groove 1031.

[0067] This design allows water to flow along the intersection of the sealing surface 102 and the protrusion 105 without affecting the sealing area of ​​the sealing surface 102 and the door frame sealing strip, facilitating the overall layout.

[0068] In the above embodiment, a protrusion 105 is provided in the door glass groove 1 to facilitate the arrangement of the drainage structure 103. By setting the drainage structure 103 as a drainage groove 1031 and a drainage hole 1032, the drainage groove 1031 can better guide the water flow entering the sealing surface 102 area to the drainage hole 1032 for discharge, thereby better preventing the water flow entering the sealing surface 102 area from entering the vehicle.

[0069] It should be understood that, in the above embodiment, the drainage groove 1031 is located at the intersection of the sealing surface 102 and the protrusion 105. The intersection of the sealing surface 102 and the protrusion 105 constitutes the preset drainage path of the drainage groove 1031. However, the preset drainage path can be located at other locations as needed, such as the drainage structure 103 and the water-blocking structure 104 being located on the same side of the sealing surface 102.

[0070] In some exemplary embodiments, a groove 1021 is provided on the side of the sealing surface 102 near the drain groove 1031. The groove 1021 is recessed towards the outside of the vehicle in the left-right direction of the whole vehicle and extends along the drainage direction of the drain groove 1031. That is, the groove 1021 extends along the intersection of the sealing surface 102 and the protrusion 105.

[0071] Specifically, in this embodiment, the sidewall of the protrusion 105 facing the sealing surface 102 is called the front sidewall. The intersection of the sealing surface 102 and the protrusion 105 extends to the intersection of the front sidewall and the sealing surface 102. In the front-rear direction of the vehicle, the front sidewall gradually slopes downward. Since the groove 1021 extends along the intersection of the sealing surface 102 and the protrusion 105, the groove 1021 also gradually slopes downward in the front-rear direction of the vehicle.

[0072] By providing a groove 1021 on the side of the sealing surface 102 near the drainage groove 1031, and defining the concave direction and extension direction of the groove 1021, the structure of the part of the sealing surface 102 near the protrusion 105 is relatively flat, so that the water flow can be better guided by the drainage groove 1031 and the groove 1021, and the water flow entering the sealing surface 102 area can be better discharged through the drainage structure 103, thereby effectively reducing the risk of rainwater entering the vehicle.

[0073] In a preferred embodiment, the cross-section of the groove 1021 is an arc, and the radius of the arc is at least 15 mm. It can be 15 mm, 16 mm, 16.5 mm, 18 mm, etc., which provides a better effect of guiding water flow along the drainage channel 1031. It should be understood that setting the radius of the arc to other values ​​is also feasible, such as 12 mm, 14 mm, etc.

[0074] In some exemplary embodiments, the upper part of the drainage channel 1031 gradually slopes away from the door glass from top to bottom. Here, by tilting the drainage channel 1031 and defining its slope from top to bottom as gradually away from the door glass, the direction of water flow can be changed, thereby effectively reducing the risk of rainwater entering the vehicle.

[0075] With this configuration, the drainage groove 1031 is actually located at the intersection of the front side wall of the protrusion 105 and the sealing surface 102. Due to the setting of the groove 1021, and the fact that the inclination direction of the drainage groove 1031 is consistent with the inclination direction of the groove 1021, a water-holding area with a large cross-section can be formed. Furthermore, water entering the sealing surface 102 area can more easily flow into the drainage groove 1031 along the groove 1021. This allows the water entering the sealing surface 102 area to smoothly enter the drainage groove 1031, thereby guiding this water flow to be discharged outside the vehicle as quickly as possible, thus improving the reliability of preventing water from entering the vehicle.

[0076] Depend on Figure 2 Combination Figure 7 and Figure 8 As shown, in some exemplary embodiments, the drain hole 1032 is disposed through the glass groove 1 in the left-right direction of the vehicle, from one end of the drain hole 1032 facing the inside of the vehicle to the other end, which is also the end of the drain hole 1032 facing the outside of the vehicle, the bottom wall of the drain hole 1032 gradually slopes downward.

[0077] In this embodiment, the drain hole 1032 extends through the glass groove 1 along the left-right direction of the vehicle, while the inclination direction of the bottom wall of the drain hole 1032 is limited, so that water can be guided to the outside of the vehicle through the drain hole 1032, effectively preventing rainwater from entering the vehicle.

[0078] It should be noted that the drain hole 1032 is connected to the cavity inside the door described below. The bottom of the cavity is provided with a water leakage hole, so that the water discharged through the drain hole 1032 can be discharged to the outside of the vehicle through the water leakage hole at the bottom of the cavity. These structures can refer to the implementation forms in the prior art, and will not be described in detail here.

[0079] Reference Figure 7 and Figure 8 As shown, in order to facilitate the installation of the glass channel 1 onto the car door, in some exemplary embodiments, a limiting part 106 is provided on the side of the glass channel 1 facing outwards. When the glass channel 1 is installed on the car door sheet metal, the limiting part 106 can be inserted into the limiting hole on the car door sheet metal, thereby limiting the installation position of the glass channel 1 on the car door sheet metal.

[0080] It should be noted that, referring to Figure 4 and combined Figure 7 As shown, the glass groove 1 is provided with an insertion hole, and the upper part of the door sheet metal of the car door is provided with an insertion part that can be inserted into the insertion groove 107. By inserting the insertion part into the insertion groove 107, the glass groove 1 can be stably installed on the door sheet metal, and the insertion part can support the glass groove 1, thereby improving the structural strength of the glass groove 1.

[0081] In detail, the structure of the door sheet metal can be referred to as described below, which includes the inner door panel and the outer door panel, which will be described in detail below. The insert on the door sheet metal is roughly triangular in shape, and its shape is consistent with the shape of the insert groove 107 in the glass groove 1, and the insert is made of metal.

[0082] With this configuration, the insert on the door sheet metal is inserted into the insert groove 107 of the glass groove 1, which can better ensure the structural strength of the glass groove 1 and improve the sealing performance of the glass groove 1.

[0083] In the above embodiment, the limiting part 106 provided on the glass groove 1 can block the edge of the limiting hole on one side when the door glass is installed on the door sheet metal, thereby limiting the insertion depth of the insert part on the door sheet metal in the insert groove 107 in the glass groove 1. This is beneficial to improving the assembly efficiency of the glass groove 1 and also to improving the installation accuracy of the glass groove 1 on the door sheet metal.

[0084] In one exemplary embodiment, the limiting part 106 is a limiting protrusion provided on the side wall of the glass groove 1 facing the outside of the vehicle, extending from the inside to the outside along the left-right direction of the whole vehicle, and the limiting protrusion protrudes outward while tilting downward.

[0085] The door sheet metal insert is provided with a limiting hole. During the process of inserting the insert into the insert groove 107, the limiting protrusion can be inserted into the limiting hole, and the edge of the limiting hole can abut against the outer peripheral wall of the limiting protrusion, thereby limiting the insertion depth of the insert in the insert groove 107.

[0086] In a preferred example, still refer to Figure 7 and Figure 8 As shown, the limiting protrusion is cylindrical, and the aforementioned drain hole 1032 penetrates the part of the glass groove 1 where the limiting protrusion is provided, making the part where the drain hole 1032 is provided thicker in the left and right direction of the whole vehicle. This allows the water flow to be better guided to the middle position in the left and right direction of the door cavity, which is conducive to the smooth drainage of water and is less likely to wash away the side walls of the door cavity along the left and right directions of the whole vehicle, thus better ensuring the service life of the door.

[0087] It is worth noting that, regarding the door sealing structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 8 As shown, it may include, for example, a glass groove 1 that can be installed on a car door.

[0088] The glass groove 1 has a groove 101 on the side facing the door glass, which can be inserted into the door glass. The inner sidewall 1011 of the groove 101 is provided with a first lip 1013 that abuts against the door glass. The upper part of the first lip 1013 is arranged vertically along the vertical direction of the whole vehicle.

[0089] The glass channel 1 has a sealing surface 102 on the side facing the interior of the vehicle for the door frame sealing strip to abut. A drainage structure 103 is provided on the side of the sealing surface 102 closest to the door glass, and a water-blocking structure 104 is provided on the side of the sealing surface 102 furthest from the door glass. A groove 1021 is provided on the side of the sealing surface 102 closest to the drainage structure 103. The groove 1021 is recessed towards the exterior of the vehicle along the left-right direction and extends along the preset drainage path of the drainage structure 103.

[0090] In this embodiment, the door sealing device limits the upper part of the first lip 1013 to be arranged vertically along the vertical direction of the whole vehicle, so that the step difference between the upper part of the first lip 1013 and the window glass is small. This results in a smaller gap between the glass groove 1 and the mating part of the door glass sealing strip and the window frame sealing strip, which can better prevent water leakage from the upper part of the sealing groove of the vehicle, thereby improving the sealing performance of the glass groove 1.

[0091] In the preferred embodiment of the sealing structure described above, the specific configuration and arrangement of the drainage structure 103, the water-blocking structure 104, the limiting part 106, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the drainage structure 103, the water-blocking structure 104, the limiting part 106, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0092] The second aspect of this application relates to a car door, which is a frameless car door, and the frameless car door is provided with a car door sealing device as described in the above embodiment.

[0093] The vehicle door described in this application, by applying the aforementioned door sealing device, can solve the problem of water leakage in the glass groove 1 area. In rainy weather, it can effectively prevent rainwater from entering the vehicle interior, thereby improving the door's sealing performance and quality. The beneficial effects of the aforementioned door sealing device compared to related technologies can still be referred to in the above embodiments, and will not be repeated here.

[0094] In a preferred embodiment, the frameless door of this embodiment has a cavity that is connected to the aforementioned drainage structure 103. Specifically, the cavity inside the frameless door is connected to the drainage hole 1032 in the drainage structure 103, and a water leakage hole is provided at the bottom of the cavity. The water leakage hole is connected to the outside space of the vehicle and faces the ground.

[0095] In specific implementation, any structural parts of the car door not mentioned in this embodiment can refer to car door structures well known to those skilled in the art, especially the various structures in frameless car doors. For example, it may include an inner door panel and an outer door panel, with the cavity located within the area enclosed by the inner door panel and the outer door panel.

[0096] In this embodiment, by providing a cavity inside the car door that communicates with the drainage structure 103, and by providing a drain hole at the bottom of the cavity, water flowing into the cavity through the drainage structure 103 can be discharged outside the vehicle through the drain hole at the bottom of the cavity. This can prevent water from entering the vehicle and improve the overall sealing performance, especially for vehicles with frameless doors. It can also better prevent water accumulation inside the door from causing corrosion of the door sheet metal and extend the service life of the door.

[0097] An embodiment of the third aspect of this application relates to a vehicle having doors as described above.

[0098] The vehicle described in this application, by using the aforementioned doors, can improve vehicle quality and customer satisfaction due to the excellent waterproof and sealing performance of the doors themselves, thereby enhancing the vehicle's market competitiveness.

[0099] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations.
