[0029] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] An embodiment of the present invention provides a vehicle door outer water cut installation assembly. Figures 1 to 7As shown, the door outer water cut installation assembly includes a door outer panel 1, an outer water cut 2 and an outer waistline reinforcement plate 3. Among them, the door outer panel 1 and the door glass 4 arranged on the inner side of the door outer panel 1 (with the vehicle itself as a reference) form a gap 5 to be sealed. The outer water cut 2 is arranged at the opening of the gap 5 to be sealed, and is used to seal the gap 5 to be sealed to prevent water on the door glass 4 and other rainwater and impurities from entering the inner cavity of the door. Structurally, the outer water cut 2 has an outer water cut body 21 overlapped on the door outer panel 1, and a sealing groove body 22 connected to the water cut body 21. After installation, the sealing groove body 22 extends into the gap 5 to be sealed. The outer waistline reinforcement plate 3 is arranged on the inner side of the door outer panel 1 and is located in the gap 5 to be sealed. The outer waistline reinforcement plate 3 has a first connecting section 31 extending toward the opening of the gap 5 to be sealed. The first connecting section 31 is configured with a self-wrapped edge 32 for adaptively inserting into the groove of the sealing groove body 22 of the outer water cut 2 for sealed connection.

[0031] Since the outer water cut 2 is an injection molded part, the sealing groove body 22 structure thereon has a relatively large width. By providing a self-wrapping 32 on the first connecting section 31, the thickness of the groove inserted into the sealing groove body 22 can be effectively adjusted to form a stable sealing fit with the sealing groove body 22. In addition, the setting of the self-wrapping 32 does not require the outer waistline reinforcement plate 3 to be thickened as a whole, which helps to achieve the lightweight of the outer waistline reinforcement plate 3, and then achieve the lightweight of the door and the vehicle. In a specific embodiment, the thickness of the outer waistline reinforcement plate 3 is 0.8 mm. After using a self-wrapping 32 once, the thickness of the outer waistline reinforcement plate 3 in the self-wrapping 32 section is 1.6 mm. This width satisfies the groove fitting connection with the sealing groove body 22, ensuring a certain friction force. It can be understood that the thickness of the self-wrapped edge 32 can be set as needed. For example, by folding the outer waistline reinforcement plate 3 once, the thickness of the self-wrapped edge 32 area can be twice that of other areas of the outer waistline reinforcement plate 3, and by folding it twice, it can form a three-fold thickness, which is used for adjusting the groove of the adaptive sealing groove body 22.

[0032] Preferably, a plurality of first sealing lips 23 are provided on the inner wall of the groove on the outer side of the sealing groove body 22. A step surface 33 located on the first connecting section 31 is formed at the self-wrapping 32, and the step surface 33 is located on the outer side of the first connecting section 31. The first sealing lips 23 are abutted on the first connecting section 31 at both ends of the step surface 33, that is, the first sealing lips 23 are abutted on the part of the first connecting section 31 at the end of the step surface 33 away from the opening of the gap 5 to be sealed, or on the part of the first connecting section 31 at the end of the step surface 33 close to the opening of the gap 5 to be sealed. Therefore, the first sealing lip 23 abutting on the thicker section of the self-wrapping 32 is greatly deformed due to the existence of the self-wrapping 32, and a stable clamping can be formed. The first sealing lip 23 abutting against the non-self-wrapped edge 32 or the segment with fewer layers of self-wrapped edge 32 has relatively small deformation, which helps to provide friction and achieve clamping. Especially when the first connecting segment 31 has a tendency to be pulled out from the sealing groove body 22, these first sealing lips 23 can be clamped with the step surface 33, effectively preventing the first connecting segment 31 from falling out of the sealing groove body 22. In addition, a plurality of sealing protrusions 27 are provided on the inner wall of the groove on the inner side of the sealing groove body 22, which are used to abut against the inner side of the first connecting segment 31, so as to further ensure the connection stability between the sealing groove body 22 and the outer waistline reinforcement plate 3.

[0033] The outer waistline reinforcement plate 3 also includes a second connecting section 34 and a third connecting section 35 which are connected in sequence and are away from the opening of the gap 5 to be sealed. The third connecting section 35 is used to be connected to the door outer panel 1 in a flat manner. The second connecting section 34 is arranged between the first connecting section 31 and the third connecting section 35. The second connecting section 34 and the first connecting section 31 form a first inner gap 51 with the door outer panel 1 to accommodate the outer groove wall of the sealing groove body 22. According to the present application, the width of the first inner gap 51 (the dimension of the first inner gap 51 in the inner and outer directions) is 4.5-5.5 mm, for example, 5 mm. This setting can ensure that the outer groove wall of the sealing groove body 22 is accommodated in the first inner gap 51, and the size is suitable, which helps to ensure the appearance effect. At the same time, the width of the first inner gap 51 helps to ensure that the sealing groove body 22 is smoothly installed, and ensures that good friction can be formed between the door outer panel 1, thereby improving the sealing requirements. In addition, a second sealing lip 24 is arranged on the outer groove wall of the outer side of the sealing groove body 22. The second sealing lip 24 is used to abut against the inner side of the door outer panel 1 to ensure sealing and increase the friction between the outer water cut 2 and the door outer panel 1, which helps to maintain the stability of the installation position of the outer water cut 2. It can be seen from the figure that the sealing gap 5 also includes a second inner gap 52, which is formed between the outer waistline reinforcement plate 3 and the door glass 4, and is mainly used to accommodate the inner groove wall of the groove wall of the sealing groove body 22.

[0034] A spring groove 11 is provided on the door outer panel 1 and the outer waistline reinforcement plate 3. The spring groove 11 extends from the open end of the gap 5 to be sealed to the position of the third connecting section 35. A spring 12 for clamping the door outer panel 1 and the outer waistline reinforcement plate 3 is provided at the spring groove 11. In other words, the door outer panel 1 is connected to the outer waistline reinforcement plate 3 by the spring 12. Preferably, a plurality of spring grooves 11 are provided in the through-length direction of the door outer panel 1 and the outer waistline reinforcement plate 3 (consistent with the extension direction of the door, for example, if the door is a side door of the vehicle, the through-length direction is consistent with the front-rear direction of the vehicle), and adjacent spring grooves 11 are spaced 200-250 mm apart. It can be understood that the spring 12 matches the spring groove 11 in number and position.

[0035] In order to improve the connection reliability between the door outer panel 1 and the outer waistline reinforcement plate 3, the two are also connected by bonding. Specifically, an adhesive tape 36 is provided on the third connection section 35 of the outer waistline reinforcement plate 3. It can be understood that the adhesive tape 36 can be provided on the surface other than the retaining spring groove 11 or the retaining tongue 37 mentioned later. In actual production, structural adhesive is pre-coated in the welding workshop, and the glue coating and baking are carried out in the welding workshop to obtain a better connection effect. Bonding and the connection with the retaining spring 12 effectively ensure the reliable connection between the door outer panel 1 and the outer waistline reinforcement plate 3, thereby making the installation and matching of each component in the door outer water-cut installation assembly more stable.

[0036] A latch tongue 37 is provided on the second connecting section 34. The fixed end of the latch tongue 37 is close to the opening of the gap 5 to be sealed, while the free end is away from the opening of the gap 5 to be sealed, and the free end protrudes inwardly relative to the fixed end. A hook 25 is provided on the groove wall on the inner side of the sealing groove body 22. The buckle 25 is provided at the opening end of the latch tongue 37 away from the gap 5 to be sealed, so as to form a snap-fit ​​match with the latch tongue 37. By providing the latch tongue 37 and the hook 25, the outer water cut 2 can be prevented from warping during use, and its own structure can be ensured, especially, the outer water cut 2 can be prevented from being disassembled by mistake. Preferably, the latch tongue 37 is formed by shearing and punching the outer waistline reinforcement plate 3. In the through-length direction of the second connecting section 34, a plurality of latch tongues 37 are provided. For example, adjacent latch tongues 37 are spaced 200-250 mm apart. In addition, it should be noted that the latch tongue 37 and the spring groove 11 are staggered, for example, adjacent 30-50 mm, to facilitate processing and layout. The arrangement of the latch tongue 37 and the retaining spring groove 11 can ensure the effectiveness and firmness of the connection between the door outer panel 1 and the outer waistline reinforcement plate 3, and can also optimize the amount of glue applied while taking into account economy.

[0037] A friction tooth 26 is protrudingly provided on the inner wall of the inner side of the sealing groove body 22. The friction tooth 26 is used to abut against the latch tongue 37 to increase friction and ensure the connection stability between the outer water cut 2 and the door outer panel 1 and the outer waistline reinforcement plate 3.

[0038] Snap-on holes 38 are provided at both ends of the outer waistline reinforcement plate 3 in the longitudinal direction. The outer water cut 2 includes water cut corner connection mechanisms (not shown in the figure) provided at both ends of the entire length. A snap-on protrusion (not shown in the figure) for inserting into the snap-on hole 38 is provided on each water cut corner connection mechanism. In other words, the outer waistline reinforcement plate 3 and the outer water cut 2 are connected at the ends of the entire length by snap connection. This arrangement can ensure that the end face of the outer water cut 2 is firmly installed, prevents warping, and helps to ensure the stable installation of the various components of the outer water cut installation assembly of the vehicle door.

[0039] The vehicle door outer water cut installation assembly of the present application has a simple structure, low cost, can provide sufficient friction for the outer water cut 2, and is firmly matched. In addition, the vehicle door outer water cut installation assembly of the present application has a beautiful appearance, and customers perceive high quality.

[0040] The present application also relates to a vehicle door, including the above-mentioned vehicle door outer water cut installation assembly and a vehicle door glass 4. The vehicle door glass 4 is arranged in an interval manner on the inner side of the vehicle door outer panel 1 to form a gap 5 to be sealed with the vehicle door outer panel 1. A third sealing lip 28 is arranged on the inner groove wall of the groove wall of the sealing groove body 22 of the outer water cut 2, so as to seal against the vehicle door glass 4 to form a sealed connection. The present application also relates to a vehicle, including a vehicle door.

[0041] In addition, in the present application, it should be noted that, unless otherwise specified, "plurality" means two or more. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] The above are only the principles and preferred embodiments of the present invention.
