[0049] Further, the main plate body in the application is provided with a flow guide mechanism, and the provision of the flow guide mechanism in the application has a good flow guiding effect, so that the water on the corner body 101 can be drained out through the flow guide mechanism, thereby avoiding the accumulation of water on the corner body 101.

[0050] Specifically, in this invention, the flow guiding mechanism is provided with a flow guiding lip 3 and a flow guiding groove 4 on the main body plate; the flow guiding lip 3 is distributed at the edge of the flow guiding groove 4; the flow guiding groove 4 is mainly used for water discharge, while the flow guiding lip 3 plays a role in limiting and converging the flow. The flow guiding lip 3 is arranged at an upward angle, which plays a good role in blocking and limiting the flow.

[0051] Meanwhile, in this invention, the flow guiding mechanism extends from the first inner connecting plate 1-11 to the second inner connecting plate 1-21; this facilitates the subsequent flow of water to the edge of the sealed circular pipe 5, and facilitates the subsequent discharge of water.

[0052] Furthermore, the main body plate described in this invention is also provided with a drainage mechanism; the drainage mechanism plays a good role in drainage, preventing water from flowing to the inner panel 10 of the car door.

[0053] The drainage mechanism described in this invention includes a corner cape 7; one end of the corner cape 7 is connected to the first outer connecting plate 1-12 and / or the second outer connecting plate 1-22, and the other end extends toward the side away from the inner door panel 10; in this invention, the corner cape 7 includes a horizontal plate and a vertical plate, the vertical plate is connected to the first outer connecting plate 1-12 and the second outer connecting plate 1-22 through the horizontal plate, and the end of the vertical plate away from the horizontal plate is provided with a drainage edge to better drain the water, so that the water flows toward the side closer to the outer door panel.

[0054] Furthermore, in this invention, the edges of the first outer connecting plate 1-12 are transitioned by an arc surface 1-13. Based on the above design, this invention makes the first outer connecting plate 1-12 without an edge structure, so that in subsequent use, the first outer connecting plate 1-12 can form a flexible transition area at the edge; weakening the strength of the straight rib structure, preventing the straight rib part from contacting the glass during glass lifting and forming a hard point contact, causing abnormal noise.

[0055] A car door assembly includes a door inner panel 10, on which a door inner water-blocking corner structure is provided; the door inner water-blocking corner structure is sleeved on the upper edge of the door inner panel 10; this arrangement ensures the sealing of the connection between the door glass and the door inner panel 10.

[0056] specific:

[0057] The corner joint structure disclosed in this invention is mainly used to solve the sealing and waterproofing problems at the joint between the frameless door glass and the inner water-blocking ends, as well as the self-fixing problem of the corner joint structure, while avoiding friction noise during the glass lifting process.

[0058] The corner joint structure disclosed in this invention mainly includes a corner joint head, wherein the corner joint head includes a corner joint body 101; the corner joint body 101 includes a main plate.

[0059] In the application, the main plate body is provided with a flow guide groove 4 on the side of the inner door panel 10; a flow guide lip 3 is arranged on the lower side of the flow guide groove 4; the purpose is to collect and guide the accumulated water in the corner joint position into the passenger compartment.

[0060] In the application, the straight connection section plate body 1-1 and the transition section plate body 1-2 are distributed in a staggered manner; the straight connection section plate body 1-1 is close to one side of the roof and has a height difference with the transition section plate body 1-2 close to one side of the roof; based on the height difference design, a height difference waterproof structure is formed.

[0061] In addition, in the application, the straight connection section plate body 1-1 and the transition section plate body 1-2 are made into an L-shaped cross-section structure, the side surface is wrapped around the glass, and a coating is sprayed on the bonding surface and the contact area to improve the wear resistance.

[0062] The lower end of the inner water-blocking corner joint structure cooperates with the sheet metal of the inner door panel 10, and the corner joint body 101 is partially designed in an n or h structure, which facilitates clamping on the sheet metal of the inner door panel 10 during subsequent use and guiding water.

[0063] In addition, in the application, a circular arc surface 1-13 is used to transition at the corner of the first outer connection plate 1-12 at the position of the glass bonding surface, and a large circular arc structure is generally used for transition to prevent abnormal noise caused by lifting friction.

[0064] In the application, the corner joint body 101 is provided with a fixed buckle 6; the fixed buckle 6 is connected with the corner joint body 101 through injection molding, and the purpose is to pre-bury the special-shaped buckle in the corner joint body 101 and fix it on the sheet metal of the inner door panel 10 by using the imitating pine burr structure of the fixed buckle 6.

[0065] In the application, the sealing circular pipe 5 wraps down the door frame strip 9 and is sealed with the side wall and the sheet metal.

[0066] As described above, the preventive measures for sealing and waterproofing are flexibly applied to the corner joint structure to improve the waterproof effect, achieve overall sealing, improve wear resistance, and reduce abnormal noise caused by lifting.

[0067] Specifically, the inner side of the corner joint structure is combined with the straight section of the inner water-blocking sealing strip (i.e., the straight section waterproof strip) and is fixedly connected to the sheet metal stop of the inner door panel; the outer side of the corner joint structure is made into a sealing circular pipe 5, which wraps the door frame sealing strip downward and cooperates with the body and accessories upward to achieve sealing; the upper end of the corner joint structure wraps the glass end and is bonded with the large surface of the glass; the lower end cooperates with the door sheet metal to form an "h" structure clamped on the side door sheet metal; the outer side uses the buckle structure to firmly fix itself on the sheet metal. The inner water-blocking corner joint structure is used as a transition to form a complete waterproof structure with the door frame strip 9, the inner water-blocking sealing strip, and the side wall accessories 8. Specific embodiments:

[0069] One end of the corner structure is connected to the straight section of the inner water-blocking sealing strip, and the other end wraps around the door frame strip 9. In the corner structure, the first outer connecting plate 1-12 and the second outer connecting plate 1-22 are bonded to the glass, and the inner side is the sealing bonding surface of the door opening strip. The upper edge of the straight connecting plate 1-1 is the first sealing ridge 1; the upper edge of the transition plate 1-2 is the second sealing ridge 2; a fixing buckle 6 is provided on the corner body 101, and the corner body 101 can be fixed to the inner panel 10 of the car door by the fixing buckle 6.

[0070] The side panel accessory 8, which is sealed in conjunction with the corner structure, forms the first sealing ring structure of the door.

[0071] Furthermore, the first sealing ridge 1 is higher than the second sealing ridge 2 at the corner, and the cliff-like structure formed by the two is outside the sealing surface. The purpose is that when rain falls, the water flow will collect along the outer edge of the glass and finally concentrate at the corner to form water accumulation. If it cannot be guided away in time, the water will spread horizontally along the first sealing ridge 1 on the corner structure and seep forward through the gap between the sealing surface and the ridge, entering the passenger compartment. Therefore, the present invention, by designing the first sealing ridge 1 to be higher than the second sealing ridge 2 at the corner, forms a height difference to prevent water accumulation from spreading to the sealing surface, thereby forming a height difference waterproofing.

[0072] In addition, the flow guiding mechanism in this invention allows for the following: when the glass seal of the frameless door fails, if water accidentally seeps into the passenger compartment, the water is absorbed at the joint between the door opening strip and the sealing surface and flows downwards. When the accumulated water flows to the corner structure, it is blocked by the flow guiding lip 3 and guided into the flow guiding groove, thus facilitating the subsequent drainage of water.

[0073] In this invention, the corners of the first outer connecting plate 1-12 are transitioned with a rounded surface to form a flexible transition area, which weakens the strength of the straight rib structure and prevents the straight rib part from contacting the glass during glass lifting and lowering, thus preventing hard point contact and abnormal noise.

[0074] The fixing buckle 6 of this invention is made of plastic and adopts a large base structure. It is then attached to the sheet metal fixing surface of the inner door panel 10, so that the corner structure is firmly attached to the inner door panel 10. In addition, the fixing buckle 6 is made of waterproof lip structure during injection molding to improve its waterproofness. Furthermore, the straight column of the fixing buckle 6 is made of imitation loose structure to further improve its firmness.

[0075] In this invention, the drainage mechanism mainly includes a corner cape 7, which is an extension of the inner water-blocking straight section n-shaped structure in the corner area and also serves as the boundary between the dry and wet areas.

[0076] The corner cape 7 has an overall cross-section in the shape of an "h". Since the cape end is in a wet area, water will accumulate and flow onto the surface. Therefore, it is required to extend downwards for a certain distance and to make a brim structure at the end for waterproofing, guiding the accumulated water away from the side door sheet metal.

[0077] The sealing round pipe 5 not only wraps the door frame strip 9, but also replaces the function of the corner area door frame, so that the door frame strip 9 structure extends to the corner structure, forms a closed loop sealing ring on the side door structure, and simulates the compression deformation state of the door frame bubble pipe, and makes a deformation avoiding space on the corner structure to meet the over-compression requirement.

[0078] Obviously, the specific implementation of the present application is not limited by the above-mentioned manner, and various non-essential improvements made by adopting the method concept and technical scheme of the present application are within the protection scope of the present application.
