Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a sliding door guide rail mounting plate and a vehicle including the sliding door guide rail mounting plate. Background Technology

[0002] Some car models feature sliding door structures, where guide rails are installed at both the top and bottom of the door on the vehicle body. The door connects to these rails and slides along them to open and close. Typically, the guide rails are first welded to connecting brackets, and then the two are welded to a mounting plate. The mounting plate also needs to be connected to a reinforcing plate before these assembled components are installed onto the vehicle body. This ensures the structural strength of the guide rail mounting area and prevents deformation that could cause the guide rails to shift, resulting in problems such as incomplete closure or uneven sliding. However, these components are numerous, occupy a large amount of space, have long dimensional chains, and significant cumulative tolerances. It is difficult to control the gap difference between the guide rail connecting brackets and the mounting plate, resulting in high installation requirements and a complex installation structure.

[0005] Both the first protrusion and the second protrusion are used to fit and connect with the outer panel of the vehicle body side wall, so that a space is formed between the fixing part and the outer panel to accommodate the guide rail.

[0006] In one possible implementation, the mounting plate includes multiple plates integrally connected together, and local sections of the multiple plates together constitute a main body area and a widening area arranged along the length direction of the fixing part.

[0007] The main body area is used to connect the straight section of the guide rail, and the widening area is used to connect the arc section of the guide rail and fix the hinge of the guide rail.

[0008] In one possible implementation, the plurality of plates includes a base plate, a first folding plate, a second folding plate, and a third folding plate;

[0009] The base plate is connected to the guide rail, and the base plate includes a straight plate segment and a curved plate segment along the first direction;

[0011] In one possible implementation, the widening area further includes a vertical plate disposed on the second folding plate and spaced apart from the end of the curved plate segment;

[0012] The vertical plate includes a plurality of plates connected at an angle in sequence. Both ends of the plurality of plates are connected to the sidewall of the first protrusion. One plate and the curved plate segment clamp the rotating arm of the hinge, and the other plate abuts against the side of the hinge seat of the hinge and is connected to the hinge seat.

[0013] In one possible implementation, the top of the vertical plate has a connecting lug, the top of one end of the guide rail is connected to the connecting lug, and the lower part is supported by the rotating arm; the end of the straight plate segment is provided with a boss, and the other end of the guide rail is connected to the boss.

[0015] The mating surfaces of the first protrusion and the second protrusion each include multiple plate surfaces connected at an angle to each other, so as to fit and mate with the plate surfaces of the outer plate.

[0016] In one possible implementation, a connecting wing plate is provided on the side of the first protrusion away from the fixing part. The connecting wing plate is arranged along a first direction and surrounds the side wall of the first protrusion to form a second docking groove for the B-pillar to be embedded, so that the groove wall of the second docking groove is in close contact with the side wall of the B-pillar.

The fixing part can directly connect to and fix the guide rail. With this design, the guide rail can be fixed and assembled onto the vehicle body using a single integrated mounting plate. That is, the guide rail can be directly fixed using a single integrated mounting plate, eliminating the need for multiple components. This not only reduces installation space requirements and facilitates installation, but also ensures a secure and close connection with the vehicle body. Furthermore, it shortens the dimensional chain, reduces accumulated tolerances, and makes it easier to meet the surface difference between the guide rail and the mounting plate, thus improving the quality of guide rail installation. Simultaneously, the mounting plate is a single cast component, which, compared to multiple spliced ​​components, provides a more stable and stronger overall structure, improving NVH performance such as modal frequency and stiffness. It also offers advantages such as reduced weight and simplified production. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please refer to the attached document. Figures 1-6 This application provides a sliding door guide rail 8 mounting plate. The structure includes a mounting plate, a guide rail 8, and a hinge 10. The mounting plate is an integral structure, a single component, such as a casting, specifically a cast aluminum part. The mounting plate extends along a first direction (the length direction of the vehicle body, the same below) and has a fixing portion 110 and a first protrusion 120 and a second protrusion 130 located at both ends of the fixing portion 110 in the first direction. The first protrusion 120 and the protrusions 130 protrude outward relative to the fixing portion 110, and both the first protrusion 120 and the second protrusion 130 are used to fit and connect with the outer panel of the vehicle body side panel; specifically, the outer panel of the side panel forming the top frame of the door frame (one side for the roof, the other side for the door). That is, the mounting plate of this integral component integrates two protrusions directly connected to the vehicle body, and a fixing portion 110 located between the two protrusions. The two protrusions are higher than the fixing part 110, while the fixing part 110 is recessed relative to the two protrusions. When the two protrusions are directly connected to the outer body panel, a space for accommodating the guide rail 8 is formed between the recessed fixing part 110 and the opposite outer body panel. In other words, the mounting plate and the outer panel of the top frame enclose the space for accommodating the guide rail 8, and the fixing part 110 can directly connect to and fix the guide rail 8. The fixing part 110 of the mounting plate is used to fix the guide rail 8 and the hinge 10 connected to the end of the guide rail 8 on the side facing the outer panel. The top of the sliding door extends into this space and can be directly connected to the guide rail 8.

[0032] As can be seen, the sliding door guide rail 8 mounting plate provided in this application can fix and assemble the guide rail 8 to the vehicle body through a single integrated mounting plate. That is, the guide rail 8 can be directly fixed by a single integrated mounting plate. For example, the guide rail 8 can be directly connected to the fixing part 110 of the mounting plate by bolts, and the two protrusions of the mounting plate can be directly welded to the vehicle body to complete the assembly. With this design, on the one hand, there is no need to combine and install multiple components, which not only reduces the installation space requirement and makes it easier to install and fit securely to the vehicle body, but also shortens the dimensional chain, reduces cumulative tolerances, and makes it easier to meet the gap surface difference between the guide rail 8 and the mounting plate, thus improving the installation quality of the guide rail 8. On the other hand, the mounting plate is a one-piece casting, which, compared with multiple spliced ​​components, provides a more stable and stronger overall structure, which is beneficial for improving NVH performance such as modal frequency (effectively attenuating vibration transmission), stiffness, and durability. It also has the advantages of reduced weight and simplified production.

[0033] In some specific embodiments, the mounting plate is a one-piece cast aluminum component. One side of the mounting plate is connected to the guide rail 8 and the hinge 10 and is used to fit and connect with the outer plate of the top frame. The other side of the mounting plate is provided with reinforcing ribs 150, which include multiple ribs arranged horizontally and vertically. With this configuration, the one-piece mounting plate has high structural strength and rigidity, which can more stably fix the guide rail 8 and ensure the durability and anti-misalignment of the guide rail 8.

[0034] The fixing part 110 extends along the first direction and has an upper flange 1 and a lower flange 6 on both sides in the second direction (the height direction of the vehicle body, the same below); the upper flange 1 is used to connect with the outer panel of the top frame, specifically by welding it to the edge of the outer panel near the roof; the lower flange 6 is used to connect with the interior panel of the vehicle body at the top frame.

[0035] The mounting plate consists of multiple integrally connected plates (distinguished by different plate angles; a plate area with a unique plate angle is referred to as a plate body). These multiple plates are integrally formed into the mounting plate through methods such as casting. Each plate body represents a region of the mounting plate.

[0036] Multiple plates together form an mounting plate. In other words, along the length direction, a portion of the plate at the first end of the multiple plates forms a first protrusion 120, a portion of the plate at the other end forms a second protrusion 130, and the plate between the two forms a fixing portion 110.

[0037] Meanwhile, to adapt to the shape of commonly used guide rails 8, the fixing part 110 is divided into a main body area 111 and a widening area 112 along the first direction, i.e., the length direction. The main body area 111 is used to connect the straight section of the guide rail 8, and the widening area 112 is used to connect the arc-shaped section of the guide rail 8. The widening area 112 is also used to accommodate and fix the hinge 10 connected to the end of the guide rail 8. With this configuration, the integrally formed fixing part 110 adapts to the shape of the guide rail 8. Divided into the main body area 111 and the widening area 112 according to the shape of the guide rail 8, it can not only accommodate and connect the straight section of the guide rail 8, but also accommodate and fix the arc-shaped section of the guide rail 8 that is deflected to one side relative to the straight section, and accommodate and fix the hinge 10 connected to the arc-shaped section. It can be seen that the entire guide rail 8 and the hinge 10 can be stably connected to the fixing part 110, and the connection is stable without the need for other brackets or plates for auxiliary fixation.

[0038] The multiple plates include a base plate 2 forming a fixing part 110, a first folding plate 3, a third folding plate 5, and a second folding plate 4; the first folding plate 3 and the second folding plate 4 are arranged along a first direction and are located between the base plate 2 and the third folding plate 5.

[0039] Specifically, the guide rail 8 is connected to the base plate 2. The base plate 2 along the first direction includes a straight plate segment 21 adapted to the straight section of the guide rail 8 and a curved plate segment 22 adapted to the arc section of the guide rail 8. The main body sections of the straight plate segment 21, the first folded plate 3, and the third folded plate 5 are connected at an angle along the second direction to form the main body area 111. The end sections of the curved plate segment 22, the second folded plate 4, and the third folded plate 5 are connected along the second direction to form the widening area 112. The hinge 10 is disposed on the second folded plate 4 and supported by the second folded plate 4.

[0040] With this configuration, the included angle between the base plate 2, the first folding plate 3, and the third folding plate 5 is an obtuse angle (in terms of the angle of the plate surface facing the guide rail 8). The overall curvature of the main body area 111 of the mounting plate is relatively small, and there are no near-right angles between the plates, which is more conducive to reducing space occupation and improving overall rigidity.

[0041] The upper flange 1 is located on the side of the base plate 2 away from the first folding plate 3, and the lower flange 6 is located on the side of the third folding plate 5 away from the first folding plate 3. That is, in the main body area 111 of the fixing part 110, the upper flange 1, the base plate 2, the first folding plate 3, the third folding plate 5 and the lower flange 6 are arranged sequentially along the second direction; in the widening area 112, the upper flange 1, the base plate 2, the second folding plate 4, the third folding plate 5 and the lower flange 6 are arranged sequentially along the second direction.

[0042] The fixing part 110 is also provided with a first docking groove 201 for the roof crossbeam to be inserted. The first docking groove 201 may have one or two arranged along a first direction. The number of first docking grooves 201 may be determined according to the number of roof crossbeams. Specifically, the first docking groove 201 is formed on the top of the base plate 2.

[0043] The widening area 112 also includes a vertical plate 7 disposed on the second folding plate 4 and spaced apart from the end of the curved plate segment 22; the vertical plate 7 includes a plurality of plates connected at an angle in sequence, the two ends of the plurality of plates being connected to the side wall of the first protrusion 120, and one of the plates being directly opposite the curved plate segment 22 and used to clamp the rotating arm of the hinge 10 with the curved plate segment 22, and the other plate abutting against the side of the hinge seat of the hinge 10 and connected to the hinge seat. With this arrangement, the shape of one side of the vertical plate 7 and the hinge 10 matches, which can stably connect and push the hinge 10, and the vertical plate 7 and the base plate 2 clamp the hinge 10, making the hinge 10 more stable.

[0044] like Figure 3 and Figure 4 As shown, a connecting lug 71 extends from the top of the vertical plate 7. The top of one end of the guide rail 8 is connected to the connecting lug 71 by bolts, and the lower part accommodates a pulley on the rotating arm and is supported by the rotating arm. A boss 23 is provided at the end of the straight plate segment 21. The other end of the guide rail 8 is connected to the platform of the boss 23 facing away from the base plate 2 by a connecting bracket 9. The connecting bracket 9 is fastened to the boss 23 by bolts. In this way, the guide rail 8 can be stably connected, and it is convenient to realize the spacing between the guide rail 8 and the base plate 2, and it is also convenient to reduce the gap difference between the guide rail 8 and the base plate 2.

[0045] Both the first protrusion 120 and the second protrusion 130 are block-shaped. Both include a mating end face extending along a second direction and sidewalls located on either side of the mating end face in a first direction. The first protrusion 120 is located at the widened region 112 end of the fixing part 110. The end of the widened region 112 is connected to the sidewall of the first protrusion 120; that is, one end of the base plate 2, the second folded plate 4, and the third folded section are all connected to the sidewall of the first protrusion 120. Both ends of the U-shaped vertical plate 7 are also connected to the sidewall of the first protrusion 120, and the first protrusion 120 closes the U-shaped opening. Thus, the structure of the widened region 112 is stable, enhancing the support and fixation of the hinge 10.

[0046] The second protrusion 130 is formed at the end of the main body region 111. The second protrusion 130 has a small volume and is formed on the main body region 111. The edge of the end of the main body region 111 is located on the outer periphery of the second protrusion 130. The outer periphery of the second protrusion 130 has a plate, which can also enhance the structural strength of this end.

[0047] In the second direction, the outer panel of the top frame is not a straight plate structure, but a curved plate with multiple bending angles or multiple sequentially connected plate surfaces; in order to enhance the fit and mating area with the outer panel, the mating end faces of the first protrusion 120 and the second protrusion 130, namely the first mating end face 121 and the second mating end face 131 shown in the figure, each include multiple plate surfaces connected in a series at an included angle, so as to fit and mate with the shape of the outer panel of the top frame.

[0048] A connecting wing plate 140 is also provided on the side of the first protrusion 120 away from the fixing part 110. The connecting wing plate 140 is arranged along the first direction and surrounds the side wall of the first protrusion 120 to form a second mating groove 141 for the B-pillar to be inserted, so that the groove wall of the second mating groove 141 is in close contact with the side wall of the B-pillar. In this way, the mounting plate extends to be in close contact with the B-pillar, with a large overall length, which not only has high structural strength and overall rigidity, but also provides a stable connection with the vehicle body, strong fixation to the guide rail, and high stability.

[0049] An embodiment of this application also provides a vehicle, which includes a body and a sliding door guide rail 8 mounting plate as described in any of the above embodiments is provided on the body.
