Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and in particular, to a vehicle sliding door assembly and a vehicle. Background Art

[0002] The side rear doors of MPV models or light bus models are generally relatively large, and the width for passengers to enter and exit after opening the door is also relatively wide, so as to form a good and comfortable access passage. At the same time, in order to solve the problem of limited lateral opening space of the side rear door, the side rear doors of most MPV models or light bus models are generally designed as track-sliding doors, and the sliding rear side door realizes sliding through the cooperation of the installed sliding hinge and the slide rail on the vehicle body side wall. The door body of the sliding side rear door of traditional MPV models or light bus models is generally divided into two parts: an outer door panel and an inner door panel assembly. Among them, the outer door panel is usually made of steel sheet by stamping thin plates. The inner door panel sheet metal assembly is usually in the form of welding of steel sheet stamping thin plate parts. The inner door panel assembly generally includes an inner door panel body and various sheet metal reinforcement plates welded thereto to achieve local reinforcement through each sheet metal reinforcement plate. Usually, it also includes a bumper beam structure for supporting the outer door panel.

[0003] Since there are multiple reinforcement plates and a bumper beam installed on the inner door panel body, the overall weight of the inner door panel assembly is large. Because each component needs to be produced separately, it involves multiple sets of molds. After each component is formed, welding equipment, welding jigs and other equipment are also required. Not only are the processes numerous, the flow is complex, the manufacturing error control accuracy is high, but the investment manufacturing cost is also relatively high.

[0004] In addition, since the sliding side rear doors of traditional MPV models or light bus models are relatively heavy, a fixed glass form is generally adopted instead of a lift glass system with higher comfort and more friendly use experience. The main reasons are as follows: First, due to the influence of each reinforcement plate and the bumper beam between the inner and outer door panels, it is very difficult to arrange the space for the glass lift drive device for driving the glass to lift; and there may also be interference problems between the glass and the reinforcement plate and the bumper beam when the glass is lifted. Second, due to the relatively large weight of the traditional sliding rear side door, higher strength requirements are put forward for the slide rail system, the sliding hinge system, and the strength of the vehicle body side wall. In order to reduce the total weight of the assembly and prevent the door from sagging and the opening from failing after long-term use, it is often necessary to abandon the lift glass system with large weight and complex structure and directly adopt fixed glass. Summary of the Invention

[0005] The present invention aims to solve at least one of the above technical problems.

[0006] To solve the above problems, the present invention provides a vehicle sliding door assembly, which includes an outer door panel and an inner door panel assembly. The inner door panel assembly includes a bumper beam, a lift glass system, and an inner door panel body with an integrated structure.

At least part of the lift glass system in the door height direction is located between the bumper beam and the inner door panel body.

[0007] In the present invention, the outer door panel of the vehicle sliding door assembly and the inner door panel body enclose a door inner cavity, and a bumper beam is also installed on the side of the inner door panel body facing the outer door panel. However, the inner door panel body has an integrated structure, and the rigidity and strength of its local positions do not need to be enhanced by separately welding additional reinforcing plates, eliminating the production molds, welding molds, etc. of each reinforcing plate in the traditional inner door panel assembly, reducing the production processes of the inner door panel assembly, simplifying the production process, and also avoiding manufacturing errors during the production of the reinforcing plate welding and processing errors during welding. The investment manufacturing cost will also be relatively low. Moreover, it can prevent the existence of traditional individual reinforcing plates from interfering with the installation and movement of the lift glass system.

[0035] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] Moreover, in the accompanying drawings, the Z-axis represents the vertical direction, that is, the up and down direction, and the positive direction of the Z-axis represents up, and the negative direction of the Z-axis represents down; the Y-axis represents the horizontal direction, that is, the left and right direction, and the positive direction of the Y-axis represents left, and the negative direction of the Y-axis represents right; the X-axis represents the longitudinal direction, that is, the front and back direction, and the positive direction of the X-axis represents front, and the negative direction of the X-axis represents back. At the same time, it should be noted that the above-mentioned meanings represented by the Z-axis, Y-axis and X-axis are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. At the same time, the coordinate axis directions described in the present invention have nothing to do with the vehicle's overall coordinate system, and are only for the convenience of describing the present invention and simplifying the description.

[0038] Among them, Figures 1-10 In the middle, the shown orientations are all schematically represented by the vehicle sliding door assembly on the left side of the vehicle. At this time, the outer door panel is located on the left side of the inner door panel assembly.

[0039] See Figures 1-3 , a vehicle sliding door assembly according to an embodiment of the present invention includes an outer door panel 4 and an inner door panel assembly. The inner door panel assembly includes a bumper beam 2, a lift glass system, and an inner door panel body 1 with an integral structure. The inner door panel body 1 and the outer door panel 4 enclose to form a door cavity. The inner door panel body 1 is provided with a first boss assembly in the direction towards the outer door panel 4. The two ends of the bumper beam 2 in its length direction are respectively installed at corresponding first bosses 11 in the first boss assembly, and one side of the bumper beam 2 away from the inner door panel body 1 is in contact with the outer door panel 4. At least part of the lift glass system in the door height direction is located between the bumper beam 2 and the inner door panel body 1.

[0040] In the vehicle sliding door assembly of this embodiment, like the prior art, the outer door panel 4 and the inner door panel body 1 enclose to form a door cavity, and a bumper beam 2 is also installed on one side of the inner door panel body 1 facing the outer door panel 4. However, the difference from the prior art is at least that the inner door panel body 1 has an integral structure, and the rigidity and strength of its local position do not need to be enhanced by separately welding additional reinforcing plates, eliminating the production molds, welding molds, etc. of each reinforcing plate in the traditional inner door panel assembly, reducing the production processes of the inner door panel assembly, simplifying the production process, and also avoiding manufacturing errors during the production of the reinforcing plates, processing errors during welding, etc., and the investment manufacturing cost will also be correspondingly reduced; moreover, it can also prevent the existence of traditional individual reinforcing plates from interfering with the installation and movement of the lift glass system.

[0041] In addition, while the bumper beam 2 supports the outer door panel 4, it does not completely occupy the door cavity in the door thickness direction. Since the two ends of the bumper beam 2 are connected to the corresponding first bosses 11 of the inner door panel body 1, in other words, only the two ends of the bumper beam 2 are in contact with the first bosses 11 of the inner door panel body 1, and most of the positions of the bumper beam 2 in the length direction except for the ends are not in contact with the inner door panel body 1. Thus, at least part of the lift glass system in the door height direction can be located between the bumper beam 2 and the inner door panel body 1, avoiding the interference of the bumper beam 2 with the installation and movement of the lift glass system.

[0042] In addition, the setting of the first boss 11 can not only ensure that there is a gap between most positions between the two ends of the bumper beam 2 and the inner door panel body 1, enabling the lift glass system to be arranged; but also strengthen the rigidity and strength of the inner door panel body 1 at the first boss 11, thereby strengthening the stability after the bumper beam 2 is fixed to the inner door panel body 1. Among them, the ends of the bumper beam 2 can be fixed to the corresponding first bosses 11 by bolts.

[0043] See Figures 1-5 And Figure 9, an outer door panel 4 is provided with an outer panel window 41, and an inner door panel body 1 is provided with an inner panel window 184 corresponding to the outer panel window 41. The lift glass system can adopt the lift glass systems of other existing non-sliding side rear doors, which includes a glass front guide rail 321, a glass rear guide rail 322, a glass upper guide rail 323, a lift glass 31 and a glass driving device 33 provided on the inner door panel body 1. The glass front guide rail 321 is fixed to the front side edge of the inner panel window 184 and extends along the height direction of the door. The glass rear guide rail 322 is fixed to the rear side edge of the inner panel window 184 and extends along the height direction of the door. The glass upper guide rail 323 is fixed to the upper side edge of the inner panel window 184 and extends along the length direction of the door (X-axis direction). The front and rear side edges of the lift glass 31 are respectively slidably connected to the glass front guide rail 321 and the glass rear guide rail 322, and the glass driving device 33 is fixed to the lower side of the inner panel window 184. The glass driving device 33 is used to drive the lift glass 31 to move up and down. The lift glass 31 moves up to the highest position where its top side edge moves into the glass upper guide rail 323. At this time, the inner panel window 184 and the outer panel window 41 are completely closed by the lift glass 31. Among them, a fourth boss 187 can also be provided on the inner door panel body 1. The fourth boss provides an installation point for the fixation of the glass driving device 33. Among them, the glass driving device can be an electric glass driving device.

[0044] See Figures 3-4 , the aforementioned "at least part of the lift glass system in the height direction of the door is located between the anti-collision beam 2 and the inner door panel body 1" means that: the bottom ends of the glass front guide rail 321, the glass rear guide rail 322, and part of the glass driving device 33 are located between the anti-collision beam 2 and the inner door panel body 1; moreover, when the lift glass 31 descends to the lowest position, at least part of the lift glass 31 will also move between the anti-collision beam 2 and the inner door panel body 1.

[0045] Optionally, the material of the outer door panel 4 is a thermosetting carbon fiber reinforced resin material, the material of the inner door panel body 1 is a magnesium alloy material, and the material of the anti-collision beam 2 is an ultra-high strength hot stamping steel material;

[0046] And / or, the inner door panel body 1 has an inner panel basic thickness area and an inner panel thickening area, and the thickness of the inner panel basic thickness area is less than the thickness of the inner panel thickening area; the outer door panel 4 has an outer panel basic thickness area and an outer panel thickening area, and the thickness of the outer panel basic thickness area is less than the thickness of the outer panel thickening area.

[0047] The material of the existing outer door panel 4 is generally steel plate, and it is formed by stamping thin steel plates; similarly, the inner door panel body 1 and each reinforcing plate in the inner door panel assembly in the prior art are also made of steel plate, and are respectively formed by stamping thin steel plates and then welded together. In this embodiment, the outer door panel 4 is made of thermosetting carbon fiber reinforced resin material, and the average thickness of the outer door panel 4 made of thermosetting carbon fiber reinforced resin material is the same as the sheet metal thickness of the original outer door panel. In addition, in this outer door panel 4, the non-linear unequal thickness structure design technology can be adopted in different parts, that is, the outer door panel 4 has an outer panel basic thickness area and an outer panel thickening area, and the thickness of the outer panel basic thickness area is less than that of the outer panel thickening area, so as to increase the local strength and anti-dent effect. On the basis of ensuring the mechanical properties and dimensional accuracy of the sheet metal structure of the original outer door panel, the weight is reduced by 50%, achieving the effect of lightweighting.

[0048] Among them, for the unequal thickness design of the outer door panel 4, refer to Figure 1 , for example, the lower side of the outer panel window can be thickened, that is, the lower side of the outer panel window is the outer panel thickening area. This position belongs to the waistline position of the vehicle sliding door assembly. By setting the outer panel thickening area here, the overall strength of the waistline of the vehicle sliding door assembly can be improved. In this way, it is not necessary to weld the outer panel upper support plate at the lower side of the inner panel window 184 of the inner door panel body 1 to support the outer door panel 4 at the waistline as in the prior art. Since there is no need to weld the outer panel upper support plate at the lower side of the inner panel window 184, it can further ensure that the movement of the lifting glass 31 will not be interfered by it. Among them, the average thickness of the outer panel basic thickness area of the outer door panel 4 is 0.9 mm, and the average thickness of the outer panel thickening area is 1 - 1.2 mm.

[0049] Among them, a third boss 186 can be provided near the lower side of the inner panel window 184. The third boss 186 has different protruding height areas along the front-rear direction of the vehicle to improve the strength of the lower side of the inner panel window 184. Of course, the third boss 186 will not affect the movement of the lifting glass 31.

[0050] In this embodiment, the carbon fiber reinforced resin material (CFRP) of the outer door panel 4 is a new composite material with synthetic resin as the matrix and carbon fiber as the reinforcement. It has properties such as high strength, high modulus, and low density. Its tensile strength is generally above 3500 MPa, which is 7 - 9 times that of ordinary steel. Therefore, the specific strength of the carbon fiber reinforced resin matrix composite material can exceed 2000 MPa / (g / cm 3 ), far higher than 59 MPa / (g / cm 3);The specific modulus is also higher than that of steel. This means that the outer door panel 4 of this embodiment has higher stiffness, strength and lower mass than the outer door panel made of steel with the same specifications.

[0051] In this embodiment, the material of the inner door panel body 1 is magnesium alloy material, which is integrally formed based on the magnesium alloy semi-solid integrated die-casting process. According to the CAE simulation analysis and optimization design technology, the non-linear unequal thickness structure design technology is adopted in different parts, that is, the inner door panel body 1 has an inner plate basic thickness area and an inner plate thickening area, and the thickness of the inner plate basic thickness area is less than that of the inner plate thickening area. Furthermore, the inner plate thickening area can replace the multi-layer and multiple reinforcing plate welding structures in the original inner door panel assembly. On the basis of ensuring that the mechanical properties and dimensional accuracy of the reinforcing plates are not reduced, the integrated structure of the inner door panel body 1 is realized through the magnesium alloy integral die-casting forming process, eliminating the original reinforcing plates, greatly simplifying the process flow and reducing the investment cost. At the same time, using magnesium alloy material to replace steel material, the weight of the whole assembly is reduced by 40%, achieving the effect of lightweight. Among them, the average thickness of the inner plate basic thickness area of the inner door panel body 1 is 2 mm to meet the minimum thickness requirement of the magnesium alloy die-casting forming process, and the average thickness of the inner plate thickening area is 2-4 mm.

[0052] In this embodiment, two anti-collision beams 2 can be provided, and the two anti-collision beams 2 are made of ultra-high-strength hot-formed steel and can be made by hot stamping. Compared with the traditional single ordinary high-strength steel anti-collision beam with a larger thickness, it not only reduces the weight but also ensures the strength at the same time. At the same time, it also provides space for the installation of the lift glass system. The arrangement quantity and position of the anti-collision beams 2 ensure the strength and stiffness of the whole assembly under extreme collision conditions to a greater extent and ensure the safety of the second-row occupants of the vehicle. Among them, the plate thickness of the anti-collision beam 2 made of hot-formed ultra-high-strength steel is 1.2 mm.

[0053] In this embodiment, the outer door panel 4 is made of a thermosetting carbon fiber reinforced resin material, the inner door panel body 1 is made of a magnesium alloy material, and the anti-collision beam 2 is made of an ultra-high strength hot stamping steel material; while the front glass guide rail 321, the rear glass guide rail 322, and the upper glass guide rail 323 can be ordinary steel plate rolled guide rails. Different connection methods are adopted between dissimilar materials. A resin bonding method is used between the steel plate rolled guide rail and the carbon fiber outer door panel 4, and the connection mechanical strength requirements are achieved after high-temperature curing (the upper parts of the upper glass guide rail 323, the front glass guide rail 321, and the rear glass guide rail 322 are bonded to the outer door panel 4; the lower parts of the front glass guide rail 321 and the rear glass guide rail 322 do not contact the outer door panel 4); a method of resin adhesive bonding plus bolt connection is used between the steel plate rolled guide rail and the inner door panel body 1 made of magnesium alloy material, and the connection mechanical strength requirements are achieved after high-temperature curing; a method of resin adhesive bonding plus bolt connection is used between the anti-collision beam 2 made of high-strength steel material and the inner door panel body 1 made of magnesium alloy material, and the connection mechanical strength requirements are achieved after high-temperature curing; a resin adhesive bonding method is used between the carbon fiber outer door panel 4 and the inner door panel body 1 made of magnesium alloy material, and the connection mechanical strength requirements are achieved after high-temperature curing.

[0054] In this embodiment, for the inner door panel body 1, only one or a set of special magnesium alloy die-casting molds need to be developed for forming the inner door panel body 1. Later, general machining equipment is used for size trimming, and one set of assembly inspection fixtures is developed to meet the product use standards, greatly reducing the investment cost and also reducing the control difficulty of manufacturing errors caused by the existence of the original reinforcement plate. In this embodiment, for the outer door panel 4, only one or a set of special carbon fiber part forming molds need to be developed for forming the outer door panel 4. Other equipment uses general autoclaves and machining equipment. One set of inner and outer panel bonding fixtures is developed, and one set of assembly inspection fixtures is developed to meet the product use standards, greatly reducing the investment cost.

[0055] Optionally, referring to Figures 4-5 and Figure 8 , at least one end of the anti-collision beam 2 is provided with a beam boss 21 corresponding to the first boss 11 in the direction of the inner door panel body 1, and the anti-collision beam 2 is connected to the corresponding first boss 11 through the beam boss 21;

[0056] And / or, the first boss assembly includes four first bosses 11, and two anti-collision beams 2 are provided. Each anti-collision beam 2 is connected to two corresponding first bosses 11 at both ends in its length direction, and the two anti-collision beams 2 are arranged in sequence along the door height direction;

[0057] And / or, a beam reinforcing rib 22 is protrudingly provided in the middle of the anti-collision beam 2 in its width direction, and the beam reinforcing rib 22 extends along the length direction of the anti-collision beam 2;

[0058] And / or, at both ends of the anti-collision beam 2 in its width direction, first beam flanges 23 bent towards the vehicle outer door panel 4 are respectively provided, the first beam flanges 23 are provided with bent second beam flanges 24, and the second beam flanges 24 are bonded to the vehicle outer door panel 4;

[0059] And / or, the anti-collision beam 2 is inclined, and the front end of the anti-collision beam 2 is lower than the rear end.

[0060] In this embodiment, referring to Figures 4-5 and Figure 8 , at least one end of the anti-collision beam 2 in the length direction is provided with a beam boss 21 towards the direction of the inner door panel body 1, and the anti-collision beam 2 is connected to the corresponding first boss 11 through the beam boss 21. In this way, on the one hand, the interval space between most positions between the two ends of the anti-collision beam 2 and the inner door panel body 1 can be further increased, and thus sufficient interval space on the Y axis can be provided for installing the lift glass system; on the second hand, by providing the beam boss 21 at at least one end of the anti-collision beam 2, the structural strength of the anti-collision beam 2 in the door thickness direction (i.e., the Y axis direction) is further improved, and the lateral anti-collision effect of the vehicle is better; on the third hand, it can be ensured that the protruding height of the first boss 11 on the inner door panel body 1 does not need to be too high, so as to ensure that there is sufficient space for arranging the lift glass system and prevent the situation that the protruding height of the first boss 11 is too high and the rigidity is not ideal; on the fourth hand, since the protruding height of the first boss 11 does not need to be designed too high, it is convenient for die casting.

[0061] In this embodiment, referring to Figures 4-5 and Figure 8 , since two anti-collision beams 2 are provided and the two anti-collision beams 2 are arranged one above the other, the vehicle outer door panel 4 can be supported at different heights, the anti-vibration effect on the vehicle outer door panel 4 is better, for the entire vehicle sliding door assembly, the lateral anti-collision effect of the vehicle is better and the occupant safety is higher. On the basis of having two anti-collision beams 2, the first boss assembly specifically includes four first bosses 11, and the end parts of each anti-collision beam 2 are respectively connected and fixed to the corresponding first bosses 11.

[0062] In this embodiment, referring to Figure 8 , most positions between the two ends of the anti-collision beam 2 are provided with beam stiffeners 22, and the beam stiffeners 22 extend along the length direction of the anti-collision beam 2. Through the arrangement of the beam stiffeners 22, the structural strength of the anti-collision beam 2 is higher. On this basis, a weight reduction hole can also be provided at the position of the beam stiffeners 22 to further reduce the weight of the vehicle sliding door assembly.

[0063] In this embodiment, referring to Figure 8, at both ends of the anti-collision beam 2 in its width direction, there are respectively first beam flanges 23 bent towards the vehicle outer panel 4. The first beam flange 23 is provided with a bent second beam flange 24. A uniform gap is maintained between the second beam flange 24 and the vehicle outer panel 4, and anti-vibration glue can be filled in the gap to bond the second beam flange 24 and the vehicle outer panel 4. Among them, the cross-section of the anti-collision beam 2 perpendicular to its length direction is in a "ji" shape. On the one hand, it can improve the rigidity and strength of the anti-collision beam 2 in the door thickness direction; on the other hand, by maintaining a uniform gap between the second beam flange 24 and the vehicle outer panel 4 and filling anti-vibration glue in the gap, the contact area and force-bearing area between the anti-collision beam 2 and the vehicle outer panel 4 can be increased; on the third hand, due to the existence of the second beam flange 24, a glue groove can be provided at the second beam flange 24 to fill anti-vibration glue in the glue groove. The anti-vibration glue in the glue groove can be bonded and fixed to the vehicle outer panel 4, and the high-frequency vibration generated by the vehicle outer panel 4 during vehicle driving can be eliminated.

[0064] In this embodiment, the anti-collision beam 2 is inclined, that is, it is arranged at an angle with the horizontal plane, and the front end of the anti-collision beam 2 is lower than the rear end. In this way, the front ends of the two anti-collision beams 2 and the corresponding first bosses 11 are all close to the lower front part of the inner door panel body 1 to strengthen the strength of the lower front part of the inner door panel body 1 and provide strength for installing the front lower sliding hinge at the lower front part of the inner door panel. In addition, as a sliding side rear door, after the vehicle sliding door assembly is closed, the middle and lower position at the rear of the vehicle sliding door assembly roughly corresponds to the H point of the second-row passenger seat (roughly at the pelvic position of the second-row passenger). The rear end of the anti-collision beam 2 can be roughly located at this position, providing a better collision protection effect for the occupants.

[0065] Optionally, refer to Figures 3-4 , when there are two anti-collision beams 2, the inclination angles of the two anti-collision beams 2 are different, and the angle between the anti-collision beam 2 located below and the horizontal plane is less than or greater than the angle between the other anti-collision beam 2 and the horizontal plane.

[0066] In this embodiment, when there are two anti-collision beams 2, not only the rear end of each anti-collision beam 2 is higher than the front end, but also the inclination angles of the two anti-collision beams 2 are different. The angle between the anti-collision beam 2 located below and the horizontal plane is less than or greater than the angle between the other anti-collision beam 2 and the horizontal plane. In this way, in the front-to-back direction, the distance between the two anti-collision beams 2 gradually decreases, and then the rear ends of the two anti-collision beams 2 are in a relatively close position, jointly providing a better collision protection effect for the occupants.

[0067] Optionally, refer to Figures 5-6, a second boss 12 facing the vehicle outer door panel 4 is provided at the front lower part of the inner door panel body 1. A first boss post 13 is provided on the second boss 12. A first boss post hole axially penetrating through the first boss post 13 is provided inside the first boss post 13. And a first boss post rib 131 is radially provided on the circumferential side surface of the first boss post 13. Wherein, the second boss 12 is used to install a front lower sliding hinge (not shown in the figure) through the first boss post 13.

[0068] In this embodiment, the protruding structure integrally formed on the inner door panel body 1, in addition to including the aforementioned first boss 11, further includes a second boss 12. The second boss 12 is provided at the front lower part of the inner door panel body 1 (the part of the inner door panel body 1 close to the positive direction of the X axis and close to the negative direction of the Z axis). And a first boss post 13 is provided on the second boss 12. A first boss post hole axially penetrating through the first boss post 13 is provided inside the first boss post 13. Thus, the second boss 12 can be used as an installation area for installing the front lower sliding hinge. It can be understood that, since the second boss 12 protrudes in the direction facing the vehicle outer door panel 4, correspondingly, a corresponding second recessed part will be formed on the side of the inner door panel body 1 away from the vehicle outer door panel 4 (the side in the negative direction of the Y axis).

[0069] When specifically installing the front lower sliding hinge, one end of the front lower sliding hinge is installed on the sliding guide rail of the vehicle side wall door frame, and the other end of the front lower sliding hinge is arranged at the second recessed part and is fixedly connected to the first boss post hole of the first boss post 13 through a bolt. A threaded sleeve made of steel (which can be a standard part) can be embedded in the first boss post hole of the first boss post 13. The bolt can connect the lower sliding hinge to the threaded sleeve in the first boss post hole, and the connection effect is stable. A first boss post rib 131 is radially provided on the circumferential side surface of the first boss post 13 to strengthen the structural strength here and ensure the strength and stability after the front lower sliding hinge is installed.

[0070] See Figure 6 , the first boss 11 corresponding to the front end of the lower anti-collision beam 2 among the two anti-collision beams 2 can be connected to the second boss 12, and further improve the strength and stability after the front lower sliding hinge is installed through this first boss 11 beside the second boss 12.

[0071] Optionally, see Figures 9-10, one of the first bosses 11 in the first boss assembly is a set first boss 14, and the set first boss 14 is located at the middle position of the rear part of the inner door panel body 1 (the part of the inner door panel body 1 close to the negative direction of the X-axis and located at the middle position in the Z-axis direction), and the inner door panel body 1 is provided with a second boss 15 around the set first boss 14 toward the door outer panel 4, and the second boss 15 is provided with a second boss hole extending through the axial direction thereof, and the peripheral side surface of the second boss 15 is provided with a second boss rib 151 along the radial direction thereof, wherein the second boss 15 is used to install a rear sliding hinge (not shown in the figure).

[0072] In the present embodiment, the first boss 11 corresponding to the rear end of the upper anti-collision beam 2 of the two anti-collision beams 2 is set as the first boss 14, and the first boss 14 is set to be located approximately in the middle position of the rear part of the inner door panel body 1. Therefore, the first boss 14 can also be used as an area for installing the rear sliding hinge, and a second boss 15 is set around the first boss 14. For example, a second boss 15 is set near the upper and lower sides of the first boss 14, and a second boss hole is axially penetrated inside the second boss 15. It can be understood that since the first boss 14 is set to protrude toward the direction of the vehicle door outer panel 4, correspondingly, a side of the inner door panel body 1 away from the vehicle door outer panel 4 (the side in the negative direction of the Y-axis) will form a corresponding set first recessed portion at the set first boss 14.

[0073] When installing the rear sliding hinge, one end of the rear sliding hinge is installed on the sliding guide rail of the vehicle side door frame, and at least part of the other end of the rear sliding hinge is arranged in the set first recessed portion, and is connected and fixed to the second boss hole of the nearby second boss 15 by bolts. Among them, the second boss hole of the second boss 15 can be embedded with a steel threaded sleeve (which can be a standard part), and the rear sliding hinge can be connected to the threaded sleeve in the second boss hole by bolts, and the connection effect is stable. Among them, the peripheral side surface of the second boss 15 is provided with a second boss rib 151 along its radial direction to strengthen the structural strength here and ensure the strength and stability of the rear sliding hinge after installation. See. Figure 10 The bottom end of the glass rear guide rail 322 extends to the location where the first boss 14 is set, so as to further improve the strength and stability of the rear sliding hinge after installation.

[0074] Alternatively, see Figure 5 , Figure 7 and Figures 9-10 The inner door panel body 1 includes an inner door panel body and an inner panel enclosure side wall arranged at the edge of the inner door panel body, and a corner reinforcement rib 16 is arranged between the inner panel enclosure side wall and the inner door panel body.

[0075] Similar to the traditional inner door panel body 1, the inner door panel body 1 in this embodiment also has an inner panel enclosing side wall. The inner door panel body 1 is connected to the outer door panel 4 through the inner panel enclosing side wall to enclose a door inner cavity. Among them, an "L"-shaped corner reinforcing rib 16 is provided between the inner panel enclosing side wall and the inner door panel main body to enhance the rigidity and strength between the inner door panel main body and the inner panel enclosing side wall. Herein, the inner door panel main body refers to the part of the inner door panel body 1 excluding the inner panel enclosing side wall.

[0076] Optionally, referring to Figure 5 and Figure 7 , the inner panel enclosing side wall includes an upper enclosing side wall 171. A first convex block 181 is provided at the front position between the upper enclosing side wall 171 and the inner door panel main body. A first convex block hole penetrating in the thickness direction of the upper enclosing side wall 171 is provided inside the first convex block 181. The first convex block 181 is used for installing a front upper sliding hinge (not shown in the figure).

[0077] In this embodiment, not only the corner reinforcing rib 16 is provided between the upper enclosing side wall 171 and the inner door panel main body, but also a first convex block 181 is provided at the front position between the upper enclosing side wall 171 and the inner door panel main body. Thus, the convex block is used to provide an installation point for the front upper sliding hinge. When specifically installing the front upper sliding hinge, one end of the front upper sliding hinge can be first installed on the sliding guide rail of the vehicle side wall door frame, and the other end of the front upper sliding hinge is placed on the upper side of the upper enclosing side wall 171 and can be connected and fixed to the first convex block hole of the first convex block 181 through a bolt.

[0078] Optionally, referring to Figures 6-7 , the inner panel enclosing side wall includes a front enclosing side wall 172. A second convex block 182 is provided at the upper position between the front enclosing side wall 172 and the inner door panel main body. A second convex block hole penetrating in the thickness direction of the front enclosing side wall 172 is provided inside the second convex block 182. The second convex block 182 is used for installing a door upper positioning block (not shown in the figure); a third convex block 183 is provided at the lower position between the front enclosing side wall 172 and the inner door panel main body. A third convex block hole penetrating in the thickness direction of the front enclosing side wall 172 is provided inside the third convex block 183. The third convex block 183 is used for installing a door lower positioning block (not shown in the figure).

[0079] In this embodiment, not only is the corner reinforcing rib 16 provided between the front enclosure side wall 172 and the inner door panel main body, but also a second bump 182 is provided at the upper position between the front enclosure side wall 172 and the inner door panel main body, and a third bump 183 is provided at the lower position between the front enclosure side wall 172 and the inner door panel main body. In this way, the second bump 182 can provide an installation point for the positioning block on the door, and the third bump 183 provides an installation point for the lower positioning block on the door. When specifically installing the upper positioning block on the door, the upper positioning block on the door is first placed on the front side of the front enclosure side wall 172, and then the upper positioning block on the door is connected and fixed to the second bump hole of the second bump 182 by bolts; when specifically installing the lower positioning block on the door, the lower positioning block on the door is first placed on the front side of the front enclosure side wall 172, and then the lower positioning block on the door is connected and fixed to the third bump hole of the third bump 183 by bolts. It can be understood that when the vehicle sliding door assembly slides forward to the maximum open position, the upper positioning block on the door and the lower positioning block on the door are in contact with and limited by the corresponding structures on the vehicle side wall.

[0080] Among them, steel threaded sleeves can be embedded in the first bump hole of the first bump 181, the second bump hole of the second bump 182, and the third bump hole of the third bump 183, so as to respectively improve the connection strength and stability of the front upper sliding hinge, the upper positioning block on the door, and the lower positioning block on the door.
