Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to an integrally formed outer water cut at the end of a frameless vehicle door. Background Art
[0002] The outer water cut is the main structure on the vehicle door. It is the intermediate structure between the door sheet metal and the window glass. It can play the role of waterproofing, dustproofing, and noise reduction. In addition, it can also decorate the appearance of the vehicle and improve the quality of the vehicle.
[0003] Currently, existing frameless door exterior watertight fittings on the market, such as the semi-hidden exterior watertight fitting installation structure and door disclosed in patent CN117719314A, feature a semi-hidden exterior watertight fitting between the door outer panel and the door inner panel. The holes between the semi-hidden exterior watertight fitting and the ends of the door outer panel and the door inner panel are partially blocked by the hidden watertight fitting end caps, while the remaining holes are blocked by internal water retaining corners. Furthermore, the main structure of the semi-hidden exterior watertight fitting is made of rubber, and the main body of the semi-hidden exterior watertight fitting is provided with a U-shaped cavity. The U-shaped cavity is provided with multiple inner lips. The top of the door sheet metal is inserted into the U-shaped cavity and restrained by the inner lips, enabling the exterior watertight fitting to be installed on the door. Furthermore, the semi-hidden exterior watertight fitting is provided with multiple functional tongues that tightly abut the sidewalls of the vehicle window glass. The functional tongues contact the window glass, achieving waterproof, dustproof, and noise reduction. Although the above structure can already meet the use requirements of external water-cutting on frameless car doors, during processing, it is usually adopted to process the external water-cutting main body first, and then squeeze the water-cut end cover from the end of the main body into the cavity of the main body, and fix the water-cut end cover on the main body by means of blocks, glue, etc. In addition, in order to improve the connection reliability, the overall length of the water-cut end cover is longer so that there are more connection parts between the water-cut end cover and the main body. In addition, in order to facilitate the subsequent extrusion and insertion operation, the water-cut end cover is larger in size, and a larger cavity needs to be reserved on a smaller main body for installation, and more inner lips need to be set in the cavity of the main body, which increases the difficulty of processing. In addition, the existing water-cut end covers on the market are usually made of hard materials, which are different from the rubber used in the main body. If deformation occurs during later use, gaps are likely to appear between the water-cut end cover and the main body, affecting the performance. Summary of the Invention
[0004] In response to the above-mentioned problems existing in the prior art, the present invention aims to provide an integrally molded external water-cut end portion of a frameless door, so that the water-cut end cover is made of the same material as the water-cut main body, and the water-cut end cover and the water-cut main body are an integral injection molding structure, which can not only avoid the problem of a long length required for extrusion insertion connection, but also effectively simplify the structure of the part where the water-cut end cover is connected to the water-cut main body, making processing more convenient.

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 7 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.
[0027] Figure 1 This is a schematic installation diagram from one perspective of an embodiment of the utility model of a frameless vehicle door end integrally formed with an outer water cut; Figure 2 This is a schematic installation diagram of another perspective of an embodiment of the frameless door end integrally formed outer water cut of the present invention. Figure 1 and Figure 2 As shown, the one-piece outer water-cut portion of the frameless door end provided in this embodiment includes: a water-cut main body 2 , a water-cut end cover 3 and a bright strip 4 .
[0028] Figure 3 for Figure 1 The cross-sectional view along line AA. Figure 1 、 Figure 2 as well as Figure 3As shown, the water-cut main body 2 and the water-cut end cap 3 are both made of rubber, so that the water-cut main body 2 and the water-cut end cap 3 are made of the same material. When the water-cut main body 2 and the water-cut end cap 3 are integrally injection-molded, when deformation occurs during use, the problem of different deformation amounts caused by the different materials of the two will not occur, thereby avoiding the problem of a gap between the two due to different deformation amounts. In addition, the inner cavity 21 of the water-cut main body 2 extends through the end. At this time, the water-cut end cap 3 is set at one end of the water-cut main body 2, and one end of the water-cut end cap 3 is inserted into the inner cavity 21 of the water-cut main body 2. A connection portion is formed between the water-cut end cap 3 and the end inserted into the inner cavity 21 of the water-cut main body 2 and the water-cut main body 2, further increasing the stability of the connection between the two. Furthermore, the water-cut end cap 3 and the water-cut main body 2 are an integral injection-molded structure, which not only avoids the problem of poor firmness when the water-cut end cap 3 is installed by extrusion, insertion, bonding, etc. in the later stage, but also reduces the length of the water-cut end cap 3 inserted into the inner cavity 21 of the water-cut main body 2, simplifies the structure of the joint between the water-cut end cap 3 and the water-cut main body 2, and facilitates processing and manufacturing. In addition, a bright strip 4 is arranged along the length direction of the water-cut main body 2 and covers the outer surface of the water-cut main body 2, and the bright strip 4 increases the appearance of the appearance. In addition, an end cover plate 41 extending toward the inner side of the water-cut main body 2 is provided at the end of one end of the bright strip 4, and after the water-cut end cap 3 and the water-cut main body 2 are formed, the end cover plate 41 of the bright strip 4 covers the outside of the water-cut end cap 3, so that the bright strip 4 includes the side of the water-cut main body 2 while also wrapping the end of the water-cut end cap 3, so that the outer surface of the outer water-cut is better in integrity and more beautiful.
[0029] Specifically, the end cover plate 41 at the end of the bright strip 4 is formed by bending the end of the bright strip 4 to one side, so that the end cover plate 41 and the bright strip 4 are an integrated bending structure, which improves the connection strength between the end cover plate 41 and the bright strip 4, further improves the integrity of the outer surface of the outer water cut, and increases the aesthetics.
[0030] Figure 4 for Figure 1 The cross-sectional view along line BB. Figure 1 and Figure 4 As shown, one end of the water-cut end cover 3 inserted into the inner cavity 21 of the water-cut main body 2 is arranged in an inverted triangle shape. At this time, the large head end of the water-cut end cover 3 at one end of the triangular arrangement is inserted into the deepest part of the inner cavity 21 of the water-cut main body 2. Preferably, the end cavity opening of the inner cavity 21 of the water-cut main body 2 is arranged in an inward-contracted manner, so that after one end of the water-cut end cover 3 is inserted into the inner cavity 21 of the water-cut main body 2, it can be blocked by the end of the water-cut end cover 3 arranged in an inverted triangle shape and the inner wall of the constriction of the inner cavity 21 to prevent the water-cut end cover 3 from falling out in the reverse direction, thereby further improving the stability and reliability of the water-cut end cover 3 after being connected to the water-cut main body 2.
[0031] More specifically, an end sealing structure 31 is provided below the end of the water-cut end cover 3 exposed from the water-cut main body 2. At this time, the end sealing structure 31 is extended into the gap of the door sheet metal 1, and the gap on the door sheet metal 1 is covered by the end sealing structure 31. Since the water-cut end cover 3 and the water-cut main body 2 are an integrated injection molding structure, the end sealing structure 31 provided below the water-cut end cover 3 can also serve as a part of the external water-cut, which can not only meet the sealing of the gap of the door sheet metal 1, and play the role of waterproofing, dustproofing and noise reduction, but also improve the integrity of the door appearance, and further improve the appearance of the vehicle.
[0032] Figure 5 for Figure 1 Cross-sectional view along CC line; Figure 6 for Figure 1 Cross-sectional view along line DD; Figure 7 for Figure 2 The enlarged view of part E in the figure. Figure 1 、 Figure 5 as well as Figure 6 and Figure 7 As shown, a embedding groove 311 is further provided below the end sealing structure 31. When the end sealing structure 31 is covered on the notch of the vehicle door sheet metal 1, the edge of the notch of the vehicle door sheet metal 1 is inserted into the embedding groove 311, so that the two sides of the end sealing structure 31 can respectively cover and abut against the two sides of the edge of the notch of the vehicle door sheet metal 1, thereby realizing a plug-in connection between the two, which not only improves the connection strength and stability of the two, but also increases the contact area of the connection part of the two, thereby improving the sealing performance.
[0033] More specifically, a connection portion is provided between the end sealing structure 31 and the water-cut end cap 3. In this case, one end of the connection portion is connected to the lower portion of the water-cut end cap 3, and the other end of the connection portion is connected to one side of the end sealing structure 31. In other words, the water-cut end cap 3 and the end sealing structure 31 are connected as a whole via the connection portion. Furthermore, the end sealing structure 31, the water-cut end cap 3, and the connection portion are made of the same material, thus unifying the materials of the three. Furthermore, the three are an integral injection-molded structure, further enhancing their integrity. This also avoids gaps caused by deformation and the occurrence of separate parts falling off, resulting in better integrity and a more aesthetically pleasing appearance.
[0034] More specifically, a snap-in groove 22 is provided on both sides of the outer side of the water-cutting main body 2. At this time, the two sides of the bright strip 4 are bent to form snap-in edges 42. When the bright strip 4 is installed on the water-cutting main body 2, the snap-in edges 42 of the bright strip 4 are respectively snapped into the two snap-in grooves 22, thereby achieving snap-in installation of the bright strip 4 on the water-cutting main body 2, making disassembly and assembly more convenient and facilitating later maintenance and replacement. Furthermore, a pre-tightening lip 23 is provided on the outer side of the water-cutting main body 2. During installation, the pre-tightening lip 23 is pressed against the side of the bright strip 4 close to the water-cutting main body 2. The pre-tightening lip 23 provides a reverse thrust for the bright strip 4, allowing the bright strip 4 to receive the thrust from the side away from the water-cutting main body 2, thereby allowing the snap-in edges 42 of the bright strip 4 to fit more closely into the snap-in grooves 22, thereby preventing the bright strip 4 from loosening and other problems.
[0035] More specifically, a shielding groove 24 is provided at the bottom of the inner side surface of the water-cut main body 2. When the outer water-cut is installed on the door sheet metal 1, the top injection-molded corner 6 of the inner water-cut installed on the door sheet metal 1 is inserted into the shielding groove 24. That is, the shielding groove 24 on the water-cut main body 2 provides conditions for the coordination of the outer water-cut and the inner water-cut, thereby realizing the hidden installation between the inner water-cut and the outer water-cut. At the same time, both sides of the top injection-molded corner 6 of the inner water-cut are wrapped and covered, thereby enhancing the stability of the connection between the two, and increasing the contact area at the connection between the two, and the connection reliability is higher.
[0036] More specifically, a functional tongue 25 is provided on the inner side of the water-cut body 2. After the formed outer water-cut is installed on the vehicle door sheet metal 1, a velvet tape 251 is provided on one side of the functional tongue 25 and abuts against the vehicle window glass. The velvet tape 251 on the functional tongue 25 contacts the vehicle window glass, which not only meets the requirements of sealing, waterproofing, dustproofing, and noise reduction, but also prevents scratches on the glass, making the structural design more reasonable. At the same time, the bottom of the functional tongue 25 is protruded downward to form an inner water-cut shielding portion 252. A gap is provided between the inner water-cut shielding portion 252 formed by the downward protrusion and the inner side of the water-cut body 2. This gap constitutes a shielding groove 24 for cooperating with the top injection-molded corner 6 of the inner water-cut, which can realize the structural utilization of the functional tongue 25, has a simple structure, and is easy to manufacture.
[0037] More specifically, a metal frame 5 is embedded in the water-cut body 2 , which increases the structural strength of the water-cut body 2 and maintains shape stability, thereby ensuring that the formed external water-cut is more stable after being installed on the door sheet metal 1 .
[0038] The frameless door end provided in this embodiment has an integrally formed external water-cut, including a water-cut main body 2, a water-cut end cover 3 and a bright strip 4; by arranging a water-cut end cover 3 of the same material in the inner cavity 21 at one end of the water-cut main body 2, the material of the water-cut end cover 3 and the water-cut main body 2 is consistent, and the water-cut end cover 3 and the water-cut main body 2 are an integrated injection molding structure, which is not only convenient to process, but also can shorten the length of the water-cut end cover 3 inserted into the inner cavity 21 of the water-cut main body 2 while ensuring the connection strength, simplify the structure of the connection between the water-cut end cover 3 and the water-cut main body 2, and facilitate processing and manufacturing. In addition, the water-cut main body 2 and the water-cut end cover 3 of the same material can prevent the problem of gaps due to deformation during later use, thereby ensuring the performance of the external water-cut and adapting to the use environment of the frameless door.
[0039] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
