Of course, the described embodiments are only a part of the embodiments of the present invention, and are not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without any creative efforts fall within the scope of protection of the present invention.

[0019] In describing the present invention, it should be understood that the orientations or positional relationships indicated by the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. are based on the drawings and are merely intended to facilitate explanation of the present invention and simplify the description, and do not expressly or imply that the devices or elements described necessarily have a specific orientation or are configured or operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0020] Example 1 As shown in FIG. 2 , this stepless vehicle door system mainly includes a vehicle door glass assembly, a glass guide rail 100, a door sheet metal 200, and a door pillar 300. The vehicle door glass assembly further includes a vehicle door glass 400, a vehicle door glass slider 500, and a glass run sealing strip 600. The door pillar 300 is riveted to the door sheet metal 200 by a metal fastener 700. The door pillar is directly assembled to the door sheet metal 200 from the X direction. The guide rail is fixed to the door sheet metal 200 by a fixing part 800. However, the fixing is not limited to rivet fixing, and may be replaced with a bolt, a fastener, a tapping screw, a snap, etc. The glass guide rail 100 is formed with a mounting cavity 101 and an insertion portion 102 that can be inserted into the lower opening of the arch portion 601 and fitted thereto. The door pillar 300 is attached to one side of the door sheet metal 200 and pressed against the pressing lip 602. The pressing lip 602 is covered by the vehicle door glass slider 500, so as to maintain a good appearance effect. After compression, the lip edge comes into contact with the vehicle door glass slider 500, so as to ensure good sealing and compression load. The left side of the glass run sealing strip 600 has a lateral limiting groove 603, into which the door sheet metal 200 is inserted. The right side of the glass run sealing strip 600 has a right-hand groove attached to the glass guide rail 100. The glass run sealing strip 600 has a side lip 604, and a pressing lip 602 is formed on the glass run sealing strip 600. The pressing lip 602 is located between the lower edge of the vehicle door glass 400, the door pillar and the vehicle door glass slider 500, and is pressed against the vehicle door glass slider 500 from above, thereby further ensuring the operating position of the door slider. The glass run sealing strip 600 has a first abutting lip edge 605 and a second abutting lip edge 606. The first abutting lip edge 605 is bonded to the bottom of the vehicle door glass 400, and the second abutting lip edge 606 is bonded to the vehicle door glass slider 500, thereby ensuring the smooth sliding of the vehicle door glass slider 500. Here, the right lip 604 is a deformable lip edge.The glass guide rail 100 and the glass run sealing strip 600 can accommodate tolerances, provide clamping force, and maintain stability after assembly of the glass run sealing strip 600. The pressing lip 602, the first abutting lip edge 605, and the second abutting lip edge 606 play a major sealing role. The pressing lip 602 is designed with a "7"-shaped lip edge. After compression, the turning back lip edge comes into contact with the vehicle door glass slider 500 and maintains good sealing force with the vehicle door glass 400. In addition to performing a sealing role, the first abutting lip edge 605 and the second abutting lip edge 606 also exert a reaction force against the vehicle door glass 500 to keep the vehicle door glass 500 in a reasonable position for stable operation. The glass run sealing strip under the door pillar is formed with a third adhesive lip edge 608, which ensures a seal with the door pillar 300. The sealing plastic foam 900 on the glass guide rail 100 can ensure the glass guide rail 100's installation position in the vehicle door system to prevent water from entering the driver's compartment. As shown in FIG. 3 , the glass guide rail 100 can be an integrated or separate guide rail, with the glass guide rail 100 sliced ​​above its waistline to form a mounting cavity 101 for the vehicle door glass assembly together with the door pillar 300. In this embodiment, an integrated guide rail is used because it avoids the relative positional deviation that occurs when the upper and lower guide rails are installed separately and avoids the problem of inserting grooves into the ends of the upper and lower guide rails of the vehicle door glass 400, thereby simplifying the structure and reducing the number of components and ensuring more stable operation of the glass. The guide rail is made of aluminum alloy to ensure overall rigidity.

[0021] In use, the vehicle door glass assembly is mounted in the mounting cavity 101 to restrict movement in the X and Y directions, and the vehicle door glass slider 500 drives the vehicle door glass 400 to move so that the surface of the vehicle door glass 400 and the surface of the door pillar 300 are at the same level, i.e., the surface of the vehicle door glass 400 is flush with the door pillar 300, thereby improving the appearance of the finished vehicle, reducing air resistance when the vehicle is traveling, improving vehicle comfort, realizing stable lifting and lowering of the vehicle door glass, and ensuring the mounting position.

[0022] This patent is mainly realized by the mutual cooperation of the vehicle door glass slider 500, the glass lant sealing strip 600 and the glass guide rail 100. Specifically, as shown in Figures 4 and 5, the vehicle door glass slider 500 is connected and fixed to the vehicle door glass 400 and cooperates with the glass lant sealing strip 600. The vehicle door glass slider 500 includes an extended first member 501 and a second member 502, and the underside of the first member 501 is formed with two lower opening fitting structures that fit with the glass lant sealing strip 600. Here, the lower opening fitting structure is a U-shaped groove 5011. Specifically, a U-shaped groove 5011 is formed at the front end and rear end of the underside of the first member 501, respectively. A reinforcing structure is provided near the U-shaped groove 5011, and a certain gap is maintained between the glass run sealing strip 600 and other positions, thereby restricting the position of the vehicle door glass 400 and avoiding any influence on the locking of the vehicle door glass 400 during operation or the lifting and lowering speed of the vehicle door glass 400. The U-shaped groove 5011 has guide arc openings 5012 at both ends, which can be used to guide the vehicle door glass 400. When assembling the vehicle door glass slider 500, it can be ensured that the vehicle door glass slider 500 smoothly enters the groove, and the edge of the vehicle door glass slider 500 is prevented from contacting and wearing down the glass run sealing strip 600 when the vehicle door glass 400 is raised or lowered. The upper surface of the second member 502 is connected to and fixed on the vehicle door glass 400, and the vehicle door glass slider 400 is held in a limited position by the lower opening fitting structure, and slides to drive the vehicle door glass 400 to operate, so that the surface of the vehicle door glass 400 and the surface of the gate pillar are at the same level.

[0023] To achieve the installation of the vehicle door glass 400, the upper surface of the second member 502 has an adhesive groove 5021, and positioning protrusions 5022 are provided at intervals on both sides of the adhesive groove 5021. The adhesive groove 5021 can prevent the adhesive from spilling out and affecting the appearance. The positioning protrusions 5022 can ensure the reference position of the vehicle door glass 400 and the vehicle door glass slider 500 and can also accommodate tolerances in other positions to ensure the position of the vehicle door glass slider 500. The adhesive position has a guide bevel transition, which can distribute the local force at the adhesive position when the vehicle door glass 400 is in operation.

[0024] The vehicle door glass 400 is raised and lowered by the driving of the vehicle door glass slider 500, so it is necessary to ensure the mounting position of the vehicle door glass slider 500 in the X and Y directions. If the vehicle door glass slider 500 is limited to a specific mounting position in the X and Y directions, this is equivalent to ensuring that the vehicle door glass 400 and the door pillar 300 are at the same level, i.e., ensuring the gap and surface difference. As shown in FIG. 6, a Y-direction limiting protrusion 5013 is formed on the back surface of the first member 501, and the vehicle door glass assembly includes a vehicle door glass 400, a vehicle door glass slider 500, and a glass lant sealing strip 600, the glass lant sealing strip 600 having a movable cavity 607 into which the vehicle door glass slider 500 is incorporated, the vehicle door glass 400 is adhered to the vehicle door glass slider 500 by an adhesive, and the vehicle door glass slider 500 is incorporated into the movable cavity 607.

[0025] The glass run sealing strip 600 is formed with a square-shaped arch portion 601 that matches the U-shaped groove 5011, and has lateral limiting protrusions 6011 on both sides of the arch portion 601. The lateral limiting protrusions 6011 are abutted against the two inner sides of the U-shaped grooves 5011 to limit the position of the vehicle door glass slider 500 in the X direction, so that the boundary position of the vehicle door glass 400 in the X direction can be effectively guaranteed, and the glass run sealing strip The door glass slider 600 is formed with a lower boss 6012 that cooperates with the Y-direction limiting protrusion 5013, and an upper boss 5011a that abuts the bottom of the U-shaped groove 5011 is formed on the upper side of the arch portion 601. The cooperation between the Y-direction limiting protrusion 5013 and the lower boss 6012 and the engagement between the upper boss 5011a and the bottom of the U-shaped groove 5011 collectively limit the Y-direction position of the vehicle door glass slider 500, thereby effectively ensuring the Y-direction position of the glass.

[0026] <Example 2>

[0046] The second embodiment is similar to the first embodiment except for the structure of the vehicle door glass slider 500. Specifically, the position of the U-shaped groove 5011 is different. As shown in Figures 7, 8 and 9, the vehicle door glass slider 500 includes an extended first member 501 and a second member 502. The front and rear ends of the underside of the second member 502 are respectively formed with U-shaped grooves 5011. That is, the mounting position of the vehicle door glass 400 is located on the same part as the U-shaped groove 5011. The U-shaped groove 5011 has guide arc-shaped openings 5012 at both ends. The upper surface of the second member 502 has an adhesive groove 5021. Positioning protrusions 5022 are spaced apart from each other on both sides of the adhesive groove 5021. The adhesive groove 5021 can prevent adhesive from spilling out and affecting the appearance. In addition, the positioning protrusion edge 5022 ensures the reference position of the vehicle door glass 400 and the vehicle door glass slider 500 and can also absorb tolerances in other positions, thereby ensuring the position of the vehicle door glass slider 500. In addition, the adhesive position has a guide bevel transition that can distribute the local force at the adhesive position when the vehicle door glass 400 is in operation, and the U-shaped groove 5011 is located between the first abutting lip edge 605 and the second abutting lip edge 606.
