[0026] In FIG. 1 to FIG. 9, a zero-step vehicle door structure provided in this embodiment includes: a vehicle door body and a glass body 1 installed on the vehicle door body.

[0027] A window frame is arranged on the door body, and sliding grooves 3 are arranged on both sides of the window frame along the vertical direction. The glass body 1 is flush with the door body. One side of the glass body 1 is a concave surface, and the other side is a convex surface. The two edges of the glass body 1 that slide along the sliding groove 3 are provided with guide pieces 2, and the guide pieces 2 are arranged along the glass body 1. The edges of the glass body 1 are continuously arranged, and the guide piece 2 is slidably installed in the sliding groove 3.

[0028] The side of the guide piece 2 in the same direction as the concave surface is provided with an arc-shaped limiting member 4. The concave surface of the arc-shaped limiting member 4 faces the guide piece 2, and the convex surface of the arc-shaped limiting member 4 is in sliding contact within the sliding groove 3. The side of the guide piece 2 that is in the same direction as the raised surface is provided with a bump limiter 5, and the bump limiter 5 is in sliding contact within the sliding groove 3.

[0029] In order to facilitate the forming of the arc-shaped limiting member 4, a groove is formed on the side of the guide piece 2 away from the glass body 1, the end of the arc-shaped limiting member 4 is fixedly connected with the groove wall of the groove, and the convex-shaped bump limiter 5. They are arranged in pairs. The paired bump limiters 5 are arranged along the extending direction of the guide piece 2, and the grooves are provided between the pair of bump limiters 5. The guide piece 2 is also provided with an auxiliary bump 6 and an auxiliary arc-shaped member 7. The auxiliary bumps 6 are arranged on the guide piece 2 in pairs, and the auxiliary bumps 6 arranged in pairs are arranged on both sides of the groove; the end of the auxiliary arc-shaped member 7 is fixedly connected with the groove wall of the groove. In this embodiment, the auxiliary bump 6 is disposed on the side of the guide piece 2 away from the glass body 1, and the auxiliary arc-shaped member 7 is disposed on the side of the guide piece 2 facing the glass body 1. The connecting line between the paired auxiliary bumps 6 and the auxiliary arc-shaped members 7 is perpendicular to the connecting line between the paired bump limiters 5 and the arc-shaped limiting member 4. The guide piece 2 and the glass body 1 are connected by a connecting member, and the connecting member is inclined toward the concave surface of the glass body 1. The cross section of the guide piece 2 is rectangular, and the connecting member is connected to one edge of the guide piece 2. FIG. 1 is a schematic structural diagram of a guide piece installed on the B-pillar side of the glass body 1, and FIG. 2 is a structural schematic diagram of a guide piece installed on the A-pillar side of the glass body 1. The grooves on the two ends of the guide on one side of the B-pillar are provided with an arc-shaped limiting member 4, a bump limiter 5, an auxiliary bump 6 and an auxiliary arc-shaped member 7, which are in the middle of the guide on the B-pillar side. Only the arc-shaped limiting member 4 and the bump limiter 5 can be provided at the groove of the A-pillar and the groove on the guide on the side of the A-pillar.

[0030] A sealing member is installed in the sliding groove 3, the sealing member is continuously arranged along the extending direction of the sliding groove 3, and is laid on the inner wall of the sliding groove 3. The seal includes an abutting portion 8, a fitting portion 9, a sealing lip 10 and a hooking part 11. The abutting portion 8 is in contact with the side wall of the glass body 1. The fitting portion 9 is smoothly connected with the abutting portion 8, and the fitting portion 9 is fitted to the inner wall of the sliding groove 3 to define a corresponding channel of the sealing member. The arc-shaped limiting member 4 is in sliding contact with the channel of the sealing member, and the bump limiter 5 is in sliding contact with the channel of the sealing member. The sealing lip 10 is arranged on the side of the door body close to the glass body 1, and the sealing lip 10 is in contact with the glass body 1. The inner side of the door body is sequentially connected with an inner plate body 12 and a reinforcing plate 13, and the sliding groove 3 is enclosed by the reinforcing plate 13. The hooking part 11 is provided at the ends of the reinforcing plate 13 and the inner plate body 12 to wrap and seal the end portions of the reinforcing plate 13 and the inner plate body 12.

[0031] The door body includes a fixing plate 14 and a cover plate 15. The side of the fixing plate 14 facing the guide piece 2 is provided with a clamping end. The sealing lip 10 is clamped and installed in the clamping end, and the clamping end at least partially shields the sliding groove 3. The cover plate 15 is disposed outside the fixing plate 14, and the outer surface of the cover plate 15 is coplanar with the outer surface of the glass body 1.

[0032] As shown in FIGS. 5 to 9, when producing the vehicle door structure provided in this embodiment, the inner plate body 12, the reinforcing plate 13, the sealing lip 10, the glass body 1 with the guide piece 2, the fixing plate 14 and the cover plate 15 are prepared and formed according to the preset shapes. When assembling, the installer installs the reinforcing plate 13 in the corresponding groove body on the inner plate body 12, then lays the sealing lip 10 in the sliding groove 3 enclosed by the reinforcing plate 13, and then installs the guide on the glass body 1. Slide and install in the sliding groove 3 according to the preset direction, and finally cover the fixing plate 14 and the cover plate 15 on the inner plate body 12 in sequence to complete the assembly.

[0033] In the daily use process of the door structure, since the door body and the glass body 1 are not flat structures, the door body part and the glass body 1 are both smooth and have transitional arc surfaces. The pressure on the guide piece 2 on the side facing the glass body 1 is greater than the pressure on the guide piece 2 on the side facing the other surface of the glass body 1. The pressure on the side of the guide piece 2 away from the glass body 1 is greater than that on the side of the guide piece 2 facing the glass body 1. The pressure on the side of the door will cause the guide piece 2 to deform after the glass body 1 is lifted several times, causing dislocation and gaps between the glass body 1 and the door body, resulting in poor sealing and sound insulation of the glass body 1. The limit component on the guide piece 2 on the side of the concave surface and the limit component on the side of the guide piece 2 toward the glass body 1 is an arc-shaped limiting member 4. The guide piece 2 on the convex surface side and the guide piece 2 on the side facing away from the glass body 1 is set as a bump limiter 5. Since the bump limiter 5 is a solid structure, the inner side of the arc-shaped limiting member 4 is hollowed out, and is located on the glass body 1. During the lifting process, the bump limiter 5 can resist greater pressure than the arc-shaped limiting member 4, which can effectively avoid the deformation of the guide piece 2 caused by the different forces on both sides of the guide piece 2, and prevent deformation of the door body and the glass body 1. No dislocation occurs between the glass body 1 to ensure that the door body and the glass body 1 can still maintain good sealing during long-term use.

[0034] As an alternative embodiment, the guide piece 2 is not provided with a groove, and the guide piece 2 is formed between the convex bump limiter 5 and the arc-shaped limiting member 4.

[0035] The present invention also provides a vehicle door, which includes the zero-step difference vehicle door structure described in Embodiment 1. The reinforcing plate 13 is used to form a sliding groove 3, and the guide piece fixedly connected with the glass body 1 extends into the sliding groove 3. When the glass lifter drives the glass body 1 to move up and down, the glass body 1 can move in the sliding groove 3. It is ensured that the outer surface of the glass body 1 and the outer surface of the door body are coplanar; that is, there is no step difference between the glass body 1 and the door body. When viewing the window from the outside of the door, the outer surface of the glass body 1 and the outer surface of the door body are located at the same face. Through the arrangement of the sealing member, the gap between the door body and the glass body 1 can be effectively sealed, avoiding air leakage or water leakage at the connection or the gap, thereby ensuring the sealing effect of the zero-step door structure and improving the quietness in the car. The limit component on the guide piece on the side of the concave surface and the limit component on the side of the guide piece toward the glass body 1 is an arc limit component. The limit component on the guide piece on the convex surface side and the limit component on the side of the guide piece away from the glass body is set as a bump limiter 5. Since the bump limiter 5 is a solid structure, the inner side of the arc-shaped limiting member 4 is hollowed out, and the bump limiter 5 can be compared to the glass body 1 during the lifting process. The arc-shaped limiting member 4 resists greater pressure, which can effectively avoid the deformation of the guide piece 2 due to the different forces on both sides of the guide piece 2, prevent the dislocation between the door body and the glass body 1, and ensure good sealing between the door body and the glass body during long-term use.

[0036] Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. It is unnecessary and impossible to enumerate all embodiments here. The obvious changes or variations derived therefrom are still within the scope of protection of the present invention.
