[0044] Based on the above design, the straight section plate body 1-1 and the transition section plate body 1-2 disclosed in the present invention are equivalent to a double-layer plate structure, which is convenient for subsequent use and can be sleeved on the door inner panel 10.

[0045] Furthermore, in the present invention, the main plate body also includes an overlapping section plate body 1-3; the overlapping section plate body 1-3 includes an overlapping plate body 1-31, and the first inner connecting plate 1-11 is connected to the overlapping plate body 1-31 through the second inner connecting plate 1-21; the setting of the overlapping plate body 1-31 is equivalent to increasing the contact surface between the corner body 101 and the door inner panel 10, which can better ensure the fitting area between the corner head and the door inner panel 10, thereby ensuring the stability of the connection between the corner head and the door inner panel 10.

[0046] In addition, in the present invention, a fastening mechanism is provided on the main plate body; the fastening mechanism includes a fixing buckle 6 arranged on the main plate body; the setting of the fastening mechanism facilitates the installation and fixation of the corner body 101 on the door inner panel 10, and at the same time, the fixing buckle 6 is arranged on the first inner connecting plate 1-11, the second inner connecting plate 1-21 and the lap plate body 1-31. In actual production, the fixing buckle 6 is integrally formed with the main plate body.

[0047] Furthermore, in the present invention, the corner body 101 also includes a sealing circular tube 5 arranged on the main plate; the interior of the sealing circular tube 5 is hollow to form a sleeve cavity; the sealing circular tube 5 is sleeved on the door frame strip 9 through the sleeve cavity; in the present invention, one function of the sealing circular tube 5 is to ensure the main structure of the corner body 101, so that the sealing circular tube 5 acts as a reinforcement. In addition, the sealing circular tube 5 can also be sleeved on the door frame strip 9, which can not only squeeze and limit the door frame strip 9, but also ensure the accuracy and stability of the installation of the corner body 101 on the vehicle door inner panel 10.

[0048] Furthermore, in the present invention, the sealing circular tube 5 is arranged on the second inner connecting plate 1-21 of the main plate body, and an avoidance notch 51 is provided at one end of the second inner connecting plate 1-21 close to the door frame strip 9, and the avoidance notch 51 is connected with the sleeve cavity on the sealing circular tube 5; the present invention plays a good avoidance role through the setting of the avoidance notch 51, which facilitates the sleeve installation of the sealing circular tube 5 on the door frame strip 9.

[0049] Furthermore, a guide mechanism is provided on the main plate of the present invention. The setting of the guide mechanism of the present invention plays a good drainage and guiding role, which facilitates the water flowing out of the window glass to the corner body 101 to be drained out through the guide mechanism, thereby avoiding the accumulation of water on the corner body 101.

[0050] Specifically, in the present invention, the guide mechanism is provided with a guide lip 3 on the main plate body and a guide groove 4 on the main plate body; the guide lip 3 is distributed at the edge of the guide groove 4; the guide groove 4 is mainly used for water discharge, and the guide lip 3 plays a role of limiting and converging, and the guide lip 3 is arranged obliquely upward, and such a setting plays a good blocking and limiting role.

[0051] At the same time, in the present invention, the guide mechanism extends from the first inner connecting plate 1-11 to the second inner connecting plate 1-21, so that the subsequent water liquid is conveniently guided to the edge of the sealing circular tube 5, and the subsequent water liquid discharge operation is convenient.

[0052] Furthermore, in the present invention, a drainage mechanism is also provided on the main body plate; the drainage mechanism plays a good drainage role to prevent water from flowing to the door inner panel 10.

[0053] In the present invention, the drainage mechanism includes a corner cloak 7; one end of the corner cloak 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 door inner panel 10; in the present invention, the corner cloak 7 includes a transverse plate and a longitudinal plate, and the longitudinal plate is connected to the first outer connecting plate 1-12 and the second outer connecting plate 1-22 through the transverse plate, and the longitudinal plate is provided with a drainage warp at one end away from the transverse plate to better drain the water so that the water flows to the side close to the door outer panel.

[0054] Furthermore, in the present invention, an arc surface 1-13 is used for transition at the edge of the first outer connecting plate 1-12; in the present invention, based on the above design, the first outer connecting plate 1-12 does not have an edge structure, and in subsequent use, the first outer connecting plate 1-12 can form a flexible transition area at the edge; the strength of the straight rib structure is weakened to prevent the straight rib part from contacting the glass to form a hard point contact when the glass is raised or lowered, causing abnormal noise.

[0055] A vehicle door assembly includes a vehicle door inner panel 10, on which the vehicle door inner panel 10 is provided the vehicle door inner water retaining angle connection structure; the vehicle door inner water retaining angle connection structure is sleeved on the upper edge of the vehicle door inner panel 10; such an arrangement ensures the sealing of the connection between the vehicle door glass and the vehicle door inner panel 10.

[0056] specific:

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

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

[0059] In the present invention, a main body plate is provided with a guide groove 4 on one side of the door inner plate 10; a guide lip 3 is provided at the lower edge of the guide groove 4; the purpose is to collect and guide the accumulated water accidentally infiltrated at the corner position out of the passenger compartment.

[0060] In the present invention, the direct-connection section plate 1-1 and the transition section plate 1-2 are staggered; the direct-connection section plate 1-1 close to the roof side and the transition section plate 1-2 close to the roof side have a height difference; based on the height difference design, a height difference waterproof structure is formed.

[0061] In addition, in the present invention, the straight section plate body 1-1 and the transition section plate body 1-2 are made into an L-shaped cross-sectional structure, the side is wrapped with 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 retaining corner structure cooperates with the door inner panel 10 sheet metal. The corner body 101 of the present invention is partially designed to be an n or h structure, which is convenient for subsequent use to be stuck on the door inner panel 10 sheet metal for structural water conduction.

[0063] In addition, in the present invention, at the position where the first outer connecting plate 1-12 and the glass bonding surface are located, an arc surface 1-13 is used for transition at the corner, and a large arc structure is generally used for transition to prevent abnormal noise caused by lifting and lowering friction.

[0064] In the present invention, a fixing buckle 6 is provided on the corner body 101; the fixing buckle 6 is connected to the corner body 101 by injection molding, the purpose of which is to pre-embed the special-shaped buckle in the corner body 101 and fix it on the door inner panel 10 sheet metal by using the imitation loose barb structure of the fixing buckle 6.

[0065] In the present invention, the sealing round tube 5 wraps the door frame strip 9 downwards, and the sides are sealed with the side enclosure attachment 8 and the sheet metal.

[0066] In summary, the present invention flexibly applies the preventive measures of sealing and waterproofing to the corner structure to improve the waterproofing effect, while achieving overall sealing, improving wear resistance, and reducing abnormal noise during lifting.

[0067] Specifically, the inner side of the corner structure is combined with the straight section of the inner water retaining seal strip (that is, the straight section waterproof strip), and is fixedly connected to the sheet metal stop of the inner door panel; a sealing round tube 5 is made on the outer side of the corner structure, which wraps the door frame seal strip downwards and seals with the vehicle body and accessories upwards; the upper end of the corner structure wraps the end of the glass and fits with the large surface of the glass; the lower end cooperates with the door sheet metal to make an "h" structure that is stuck on the side door sheet metal; the outer side uses a buckle structure to firmly fix itself on the sheet metal. The inner water retaining corner structure is used as a transition to form a complete and closed waterproof structure with the door frame strip 9, the inner water retaining seal strip and the side enclosure accessories 8. Specific embodiment:

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

[0070] The side enclosure attachment 8, which is in sealing cooperation with the corner structure, forms the first sealing ring structure of the vehicle door.

[0071] Furthermore, the first sealing edge 1 is higher than the second sealing edge 2 at the corner, and the cliff-like structure formed by the two is outside the sealing surface; the purpose is that when it rains, the water will gather along the outer edge of the glass and finally gather at the corner to form water accumulation. If it cannot be guided away in time, the accumulated water will spread horizontally along the first sealing edge 1 on the corner structure, penetrate forward through the gap between the sealing surface and the edge, and enter the passenger compartment. Therefore, the present invention forms a height difference by designing the first sealing edge 1 to be higher than the second sealing edge 2 at the corner, thereby preventing the accumulated water from spreading to the sealing surface position, thereby forming height difference waterproofing.

[0072] In addition, with the arrangement of the guide mechanism in the present invention, when the glass seal of the frameless door fails, such as water accidentally seeping into the passenger compartment, the water will be adsorbed at the joint between the door opening strip and the sealing surface and gathered downward. When the accumulated water flows to the corner structure, it will be blocked by the guide lip 3 and guided into the guide groove, thereby facilitating the subsequent water discharge operation.

[0073] In the present invention, the first outer connecting plate 1-12 adopts arc surface transition at the corner 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 to form hard point contact when the glass is raised or lowered, thereby causing abnormal noise.

[0074] The fixing buckle 6 of the present invention is made of plastic material, and the fixing buckle 6 adopts a large base structure, which is subsequently fitted to the sheet metal fixing surface of the door inner panel 10, so that the corner structure is fitted to the door inner panel 10 as a whole and is firmly fixed. In addition, in the present invention, a waterproof lip variable structure is made during injection molding of the fixing buckle 6 to improve its own waterproofness. In addition, the straight column of the fixing buckle 6 is made into an imitation loose structure to further improve the firmness.

[0075] In the present invention, the drainage mechanism mainly includes the corner cloak 7, which is an extension of the inner water retaining straight section n-type structure in the corner area and is also the dividing line between the dry and wet areas.

[0076] The overall cross-section of the corner cloak 7 is "h"-shaped. Since the end of the cloak is in a wet area, water will fall onto the surface and flow, so it is required to extend downward for a distance and make a brim structure waterproof at the end to guide the accumulated water away from the side door sheet metal.

[0077] The sealing circular tube 5 not only wraps the door frame strip 9, but also replaces the function of the door frame in the corner area, so that the door frame strip 9 structure extends to the corner structure, forming a closed-loop sealing ring on the side door structure, and at the same time simulates the compression stress deformation state of the door frame bubble tube, and makes deformation avoidance space on the corner structure to meet the over-compression requirements.

[0078] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
